Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elastic body size inspection device for measuring dimensions of an elastic body such as an outer diameter, an inner diameter and a height (or thickness) of the annular elastic body.

[0002]

[Prior art]

 Although elastic bodies such as rubber products, such as annular elastic bodies, are used in various devices, they are required to be manufactured with high precision, and from the viewpoint of quality assurance, they can be measured with high accuracy. There is a need to. The manufacturing accuracy of the elastic body is required to have an accuracy of, for example, about 0.05 mm, and for that purpose, it is necessary for the measuring device to measure about 0.01 mm. Conventionally, calipers, CCD imaging type inspection equipment, and three-dimensional measuring machines have been used as measuring devices or measuring instruments for measuring the outer diameter, inner diameter, and height of the annular elastic body.

[0003]

[Problems to be solved by the device]

 The caliper is used by the measurer in direct contact with the ring-shaped elastic body, so the measurement results vary depending on the measurement operation. In addition, there are variations in measurement due to individual differences among measurers. In consideration of such variations, the measurement is usually performed multiple times, and there is a problem that the measurement time is long. Furthermore, since many measurement results are manually calculated or input to a computer for statistical processing, there is a problem that a complicated work of manually calculating or inputting to a computer is required. Like a caliper, a three-dimensional measuring machine is also used in contact with an annular elastic body, so the same problems as described above when using a caliper are encountered.

As a CCD image pickup type inspection apparatus, for example, a method of measuring the size of an annular elastic body using an area sensor takes into consideration that the number of pixels of a normal CCD camera is about 30 pixels. When measuring the dimensions of the annular elastic body, the accuracy is only about 0.1 mm, which does not satisfy the above-mentioned measurement accuracy. To improve the measurement accuracy, it is necessary to increase the resolution of the CCD camera, but there is a problem that the price becomes very high. It may be possible to improve the measurement accuracy by using a CCD imaging type inspection device or by measuring the annular elastic body partially rather than the whole, but the device configuration becomes complicated and the processing of the measurement results is complicated. It becomes a high-priced device.

As described above, the annular elastic body is exemplified as the elastic body, and the problem in the dimension measurement thereof is described. However, the same problem as described above is also encountered in the dimension measurement of the elastic body other than the annular elastic body. In this way, conventionally used devices and measuring instruments for measuring the dimensions of elastic bodies have problems in terms of measurement accuracy and workability. Therefore, the present invention solves the above-mentioned problems, has good workability, and can measure the dimensions of an elastic body, such as the outer diameter, inner diameter and height of an annular elastic body in a short time and with high accuracy. An object of the present invention is to provide a possible elastic body size inspection device.

[0006]

[Means for Solving the Problems]

Measurement control calculation means (200, 300, 500) for calculating the size of the elastic body (800) based on the detection signal of the laser receiver (2) that has worked and detected the laser light emitted from the laser projector (1) ) And.

The annular elastic body (800) is positioned so that its surface is orthogonal to the optical path formed between the laser projector (1) and the laser receiver (2). The measurement control calculation means (200, 300, 500) determines the outer diameter and the inner diameter of the annular elastic body (800) based on the detection signal of the laser receiver (2) when the annular elastic body (800) is in the positioning state. calculate.

Further, the dimension measurement of the elastic body includes the height (thickness) of the annular elastic body. In this case, the measurement target drive means (700, 400, 500, 900) is the annular elastic body (800). The annular elastic body (800) is positioned so that its flat surface is parallel to the optical path formed between the laser projector (1) and the laser receiver (2). The measurement control calculation means (200, 300, 500) determines the height or thickness of the annular elastic body (800) based on the detection signal of the laser receiver (2) when the annular elastic body (800) is in the positioning state. calculate. After the outer diameter and inner diameter of the annular elastic body are measured, the thickness of the annular elastic body can be continuously measured. Alternatively, after measuring the thickness of the annular elastic body, its outer diameter and inner diameter can be continuously measured.

[0009]

[Action]

 An elastic body, for example, an annular elastic body (800) is placed on the measurement target drive means (700, 400, 500, 900). When measuring the outer diameter and the inner diameter of the annular elastic body (800), the measurement target drive means (700, 400, 500, 900) is such that the flat surface of the annular elastic body (800) is the laser projector (1). The annular elastic body (800) is positioned so as to be orthogonal to the optical path formed between the laser receiver (2). Then, the measurement control calculation means (200, 300, 500) calculates the outer diameter and the inner diameter of the annular elastic body (800) from the detection light of the laser receiver (2) when the annular elastic body (800) is in the positioning state. . Further, when measuring the height of the annular elastic body (800, the driving means (700, 400, 500, 900) to be measured has a flat surface of the annular elastic body (800) as the laser projector (1).

FIG. 9 shows the entire operation of the annular elastic body size inspection device. The ring-shaped elastic body dimension inspection device is equipped with "measurement preparation operation (stage)", "measurement operation 1", "measurement operation 2", "measurement operation 3", "measurement operation 4", "judgment operation", and "result output operation". Then, the outer diameter D1, the inner diameter D2 and the height H of the annular elastic body 800 are measured. When the annular elastic body size inspection device is initialized, a preparatory operation is performed, and when the measurer presses the start PB35, the signal is output to the personal computer 300 via the measurement table controller 500. As a result, the automatic measurement operation of the annular elastic body dimension inspection device starts. This automatic measurement operation is a state in which the flat surface of the annular elastic body 800 is positioned so as to be orthogonal to the laser light L from the laser projector 1 as shown in FIGS. 3 and 7A in the measurement operation 1. Then, the outer diameter and inner diameter of the annular elastic body 800 are measured by moving the grip cylinder 8 from the return end to the discharge end, and then, in the measuring operation 2, conversely, the grip cylinder 8 is moved from the discharge end to the return end. Then, the outer diameter and the inner diameter of the annular elastic body 800 are measured again. Then, in the measurement operation 3, as shown in FIGS. 4 and 7B, the measurement table 700 positions the flat surface of the annular elastic body 800 so as to be parallel to the laser light L from the laser projector 1. In this state, the height of the annular elastic body 800 is measured by moving the grip cylinder 8 from the return end to the discharge end, and then, in the measuring operation 4, conversely, the grip cylinder 8 is moved from the discharge end to the return end. The height of the annular elastic body 800 is measured again. After that, the personal computer 300 judges the quality of the measurement result based on the standard dimension data, and outputs the result. The detailed operation example will be described below.

Preparation Operation for Measurement When measuring the dimensions of the annular elastic body 800, preparation operation for measurement is performed. When initially driven, the personal computer 300 inputs the product number of the annular elastic body 800 from the keyboard, searches the database for the standard size data of the corresponding product, and stores it. After that, the personal computer 300 outputs the measurement condition and the calculation condition to the measurement controller 200. The measurement table controller 500 drives the solenoid valve 400 and the measurement table section 700 to hold the annular elastic body 800 set on the measurement table section 700. The measurement controller 200 sets measurement conditions and calculation conditions according to the conditions supported by the personal computer 300. It should be noted that, instead of the personal computer 300 searching the database for the standard size data, the measurer may input the standard size data into the personal computer 300, but this is done to simplify the work and prevent input errors. In the example, the standard dimension data is retrieved from the database. Further, when the annular elastic body 800 is set on the rotary table 7 in the measurement table section 700, it is set so as to be positioned substantially at the center with the marking line 36 of the rotary table 7 shown in FIG. 6 as a guide.

Measurement operation 1: outer diameter / inner diameter data measurement (1) The personal computer 300 outputs a start signal to the measuring machine controller 200 and the measuring table controller 500, and the operation of the measuring machine controller 200 and the measuring table controller 500. To start. The measurement table controller 500 drives the measurement table unit 700 to lower it to the return end of the grip cylinder 8 and causes the spring 5 to grip the annular elastic body 800. The other cylinders also return to the return end and are located at the origin. The personal computer 300 transmits the measurement condition and the calculation condition to the measuring machine controller 200. The measuring machine controller 200 energizes the laser projector 1 to emit laser light toward the laser receiver 2, and operates under the measurement conditions and calculation conditions described later. During the measurement operation 1 to the measurement operation 4, the measuring machine controller 200 may continuously energize the laser projector 1 or may perform energization for each measuring operation. In this embodiment, an example in which the laser projector 1 is operated continuously will be described in consideration of the operational stability of the laser projector 1. The measurement table controller 500 drives the measurement table unit 700 to move the annular elastic body 800 from the return end of the gripping cylinder 8 to the output end thereof. The laser receiver 2 receives the laser light affected by the shape of the annular elastic body 800 held by the measurement table 700, and responds to the laser light shown in FIGS. 8 (A) and 8 (B). And outputs a detection signal to the measurement controller 200. The measurement controller 200 calculates the outer diameter and the inner diameter of the annular elastic body 800 from the detection signal from the laser receiver 2. The measuring machine controller 200 calculates the maximum value MAX of the calculated outer diameter and inner diameter and outputs it to the personal computer 300. The personal computer 300 stores the maximum value MAX.

The measurement conditions will be described in detail. As shown in FIG. 8A, when the annular elastic body 800, the grip plate 3 and the rotary table 7 on which the laser light from the laser projector 1 moves are interrupted, the laser receiver 2 interrupts the laser light. No light is received. One segment is one segment. The light-transmitting segment L3 at the center of the annular elastic body 800 indicates the inner diameter D2 of the annular elastic body 800, and the light-transmitting segment L3 and the segment portions NL2 and NL4 blocked by the contour of the annular elastic body 800 are added. The outer diameter of the annular elastic body 800 is D1. This measurement condition is also applied to measurement operation 2 to measurement operation 4. Next, the calculation conditions will be described in detail. Since the ring-shaped elastic body 800 is only placed almost in the center of the rotary table 7, there is no guarantee that the laser beam L from the laser projector 1 scans the accurate center of the ring-shaped elastic body 800. Therefore, the fried table 6 is moved in parallel to detect the maximum value MAX of the signal detected by the moving laser receiver 2 as shown in FIG. And ask. For example, when the slide cylinder 9 strokes at 10 mm / sec and the measurement controller 200 inputs the detection result of the laser receiver 2 at a cycle of 0.1 seconds, one stroke of the slide cylinder 9 makes 10 measurements. The maximum measured value in this measurement is the outer diameter and the inner diameter of the annular elastic body 800. This calculation condition is also applied to measurement operation 2 to measurement operation 4. The measurement value thus obtained is output from the measuring machine controller 200 to the personal computer 300 and stored in the personal computer 300.

Measuring operation 2: outer diameter / inner diameter data measurement (2) When the above operation is completed, the personal computer 300 outputs a start signal again to the measuring machine controller 200 and the measuring table controller 500, and these measuring machines The automatic operation of the controller 200 and the measurement table controller 500 is started. The measurement table controller 500 rotates the rotary table 7 by 90 degrees with the rotary cylinder 12, and moves the annular elastic body 800 at the output end of the gripping cylinder 8 in the measurement operation 1 in the direction opposite to the measurement operation 1 and at the return end. Move towards. The measuring machine controller 200 inputs the detection signal of the laser receiver 2 and detects the maximum value MAX of the measurement segment in the course of this movement, and uses it as the second outer diameter and inner diameter measurement data. The measuring machine controller 200 operates in the same manner as the measuring operation 1 according to the above-mentioned measurement conditions and calculation conditions, calculates the maximum values of the outer diameter and the inner diameter based on the detection signal from the laser receiver 2, and then the personal computer 300 Output to. The personal computer 300 stores the value.

Measuring operation 3: Height data measurement (1) When the measuring operation 2 is completed, the personal computer 300 outputs a start signal to the measuring machine controller 200 and the measuring table controller 500 again, and the measuring machine controller 200 And the operation of the measurement table controller 500 is started. The measurement table controller 500 reverses the fried table 6 by 90 degrees by the swing cylinder 21 in the measurement table unit 700, and moves the fried table 6 by the slide cylinder 9 from the return end to the output end. The measuring machine controller 200 inputs the detection signal of the laser receiver 2 and detects the maximum value MAX and the minimum value MIN for the height measurement of the annular elastic body 800, as shown in FIG. This is the height measurement data for the second time. This measurement data is output to the personal computer 300 and stored in the personal computer 300. The measurement conditions and the calculation conditions follow the above-mentioned conditions.

Measuring operation 4: Height data measurement (2) When the measuring operation 3 is completed, the personal computer 300 outputs a start signal to the measuring machine controller 200 and the measuring table controller 500 again, and the measuring machine controller 200 And the operation of the measurement table controller 500 is started. The measuring table controller 500 moves the fried table 6 from the outgoing end to the returning end by the swing cylinder 21 in the measuring table unit 700. The measuring machine controller 200 inputs the detection signal of the laser receiver 2 and calculates the maximum value and the minimum value for the second height measurement of the annular elastic body 800. The personal computer 300 stores the input value.

Judgment Operation The personal computer 300 averages the first and second measurement results for the outer diameter and inner diameter of the annular elastic body 800 calculated by the measuring machine controller 200 as described above. Determine the outer diameter and average inner diameter. Next, the personal computer 300 compares the standard data with the average outer diameter and the average inner diameter to determine whether or not they are within the tolerance. The personal computer 300 determines that the product is a good product (passed product) if it is within the tolerance and a defective product (failed product) if it is not within the tolerance. The personal computer 300 also compares the height measurement value of the annular elastic body 800 with the standard dimensional data to determine whether or not it is within the tolerance. The personal computer 300 stores the determination data. The personal computer 300 horizontally rotates the measurement table unit 700 via the measurement table controller 500, and returns the measurement table unit 700 to the original state. The origin return operation may be performed immediately after the measurement operation 4 is completed. During this return-to-origin operation, the measuring machine controller 200 deactivates the laser projector 1 and stops the laser light emitted from the laser projector 1. Result Output Operation The personal computer 300 outputs the above determination result to a CRT display device, a printer and the like.

As described above, according to the annular elastic body dimension inspection device, the operator simply operates the start PB 35 to automatically make the outer diameter, the inner diameter, and the height dimension of the annular elastic body 800 continuous. Can be measured. Further, the quality of the annular elastic body 800 can be automatically judged. Of course, according to the present invention, it is possible to measure only the outer diameter, the inner diameter, the outer diameter and the inner diameter, or the thickness of the annular elastic body 800. This measurement is performed in a non-contact manner using the laser light emitted from the laser projector 1. For example, an easily deformable elastic body such as a rubber annular elastic body 800 is not deformed during the measurement. Can measure dimensions with high accuracy. This measurement has high reproducibility and there is little measurement variation. Therefore, at most, the measurement operation of reciprocating from the return end to the output end is sufficient, and the annular elastic body 800 can be measured in a short time. In principle, it is only necessary to measure the dimensions during the movement from the return end to the output end, but in this embodiment, in order to improve the accuracy and to return to the origin position for the next measurement operation.

As a method for measuring the dimensions of a ring-shaped elastic body using an area sensor as a CCD image pickup type inspection apparatus, considering that the number of pixels of a normal CCD camera is about 300,000 , When measuring the size of the 50 mm annular elastic body, its accuracy is only about 0.1 mm, which does not satisfy the above-mentioned measurement accuracy. To improve the measurement accuracy, it is necessary to increase the resolution of the CCD camera, but there is a problem that the price becomes very high. It may be possible to improve the measurement accuracy by using a CCD imaging type inspection device or by measuring the annular elastic body partially rather than the whole, but the device configuration becomes complicated and the processing of the measurement results is complicated. It becomes a high-priced device.
