Description

Intelligent packaging machine structure and method

The present invention relates to a structure and method of an intelligent packaging machine that can automatically identify the status of electronic parts placed on a material belt and automatically perform focus correction on a camera element.

The manufacturing chain of electronic products usually separates parts from assembly. Parts manufacturers produce a large number of tiny electronic parts, package them, and then ship them to assembly plants for assembly. In the packaging process, taking the work tray as an example, the electronic parts are packaged in the work tray using a packaging machine, which can effectively achieve the purpose of packaging and storage, and is also convenient for transportation to other manufacturers. However, although this work tray method can achieve the purpose of transportation, the overall volume is relatively large. When the number of electronic parts packaged is relatively large, it will cause insufficient storage space.

Barcodes are often used in the packaging process of electronic components. Barcodes can be used to obtain information such as the model or manufacturer of the electronic components. However, with the current general barcode reading, it is impossible to know whether the direction of the electronic components in the material strip is correct, or whether the font is dirty, different, the electronic components are not placed, or whether the angle of the font printing is normal.

In addition, when the camera element of the aforementioned packaging machine loses focus, the user may not be able to find it immediately, which may cause the electronic parts in the package to be placed in the wrong direction, the fonts to be misaligned, etc., which may lead to the situation of missing due to the camera element losing focus.

Therefore, how to solve the above-mentioned problems and deficiencies in usage is the direction that the applicant of this invention and related manufacturers engaged in this industry are eager to study and improve.

The main purpose of the subject of this invention is to provide a method for automatically identifying the status of electronic components placed on a tape by using the imaging element of the imaging device in combination with the storage module and the electronic component status judgment module in the processing device.

Another main purpose of the present invention is to provide a method that enables the imaging element to have the advantage of automatically performing focus correction through a focus self-calibration module.

The structure of the present invention capable of achieving the above-mentioned main purposes includes a packaging platform device, wherein a first reel for placing a material tape is provided at one end of the packaging platform device, and a second reel for accommodating the material tape is provided at the other end. A camera device is provided on the packaging platform device, and the camera device includes a camera element, and the camera element is used to shoot the material tape provided by the first reel, and the camera element has a focus self-calibration module that can automatically adjust the focus of the camera element. , and a packaging device is provided between the camera device and the second reel. In addition, a processing device is provided on one side of the camera device. The processing device includes a storage module for storing the status information of the electronic component, an electronic component status judgment module information-linked to the storage module, and a stop module information-linked to the electronic component status judgment module. In addition, a reading unit is provided on the electronic component. The reading unit is information-linked to a history module for storing the production information of the electronic component.

When you want to package electronic parts, you can follow the steps below:

(a) Place a material tape on a first reel;

(b) Activate a packaging platform device and use a self-focus calibration module to perform focus calibration on the imaging element of the imaging device installed on the packaging platform device;

(c) When the material belt passes through the packaging platform device, at least one electronic component is placed into the material belt;

(d) When the material belt moves to the bottom of the imaging element, the imaging element takes pictures;

(e) The photos captured by the imaging element are judged by an electronic component status judgment module in a processing device. The electronic component status judgment module is compared with status information in a storage module. If the comparison is consistent, the operation continues and step (f) is executed. If it is inconsistent, a stop message is transmitted to a stop module to stop the operation;

(f) The material tape containing the electronic components is sealed and packaged by a packaging device, and then received by a second tape reel disposed at one end of the packaging platform device.

In addition, when the user wants to view the history of an electronic component, he can use a reader to scan the reading unit on the electronic component to display the history information of the electronic component.

By using the above technology, the problems existing in conventional packaging machines, such as the inability to know whether the direction of the electronic components in the material belt is correct, the inability to know whether the font is dirty, different, or whether the angle of the font printing and the situation where the electronic components are not placed are normal, and the inability to immediately know whether the camera element is out of focus, can be overcome to achieve the practical progress of the above advantages of the present invention.

Please refer to Figures 1 to 8 at the same time, which are the three-dimensional perspective diagrams to the action schematic diagram 5 of the preferred embodiment of the present invention. It can be clearly seen from the diagrams that the main steps include:

(a) Installing the tape: placing a tape A on a first tape reel 2;

(b) Autofocus: Start a packaging platform device 1 and use a self-focusing module 411 to perform focus correction on the imaging element 41 disposed on the packaging platform device 1;

(c) Placing electronic components: When the material belt A passes through the packaging platform device 1, at least one electronic component B is placed in the material belt A;

(d) Photographing and capturing: When the material belt A moves below the imaging element 41, the imaging element 41 takes photos and captures them;

(e) Comparison and judgment: The photo captured by the imaging element 41 is judged by an electronic component status judgment module 62 disposed in a processing device 6. The electronic component status judgment module 62 is compared with status information disposed in a storage module 61. If the comparison is consistent, the operation continues and step (f) is executed. If it is inconsistent, a stop message is transmitted to a stop module 63 to stop the operation;

(f) Packaging film: The material tape A containing the electronic component B is packaged with a film by a packaging device 5, and is received by a second reel 3 disposed at one end of the packaging platform device 1.

The above steps are described in detail as follows:

Regarding step (a), when the user wants to package the electronic component B, the material belt A can be combined with the packaging platform device 1 first, so that the material belt A can be moved under the guidance of the packaging platform device 1.

Regarding step (b), after the installation is completed, the packaging platform device 1 is started to move the material belt A (the system of the packaging platform device 1 driving the material belt A to move is a commonly used roll-to-roll packaging machine structure, so it is not repeated here), and the camera element 41 can automatically focus through the focus self-calibration module 411. For example, when the focus self-calibration module 411 of the camera element 41 is out of focus due to a malfunction and cannot automatically focus, the longitudinal bracket drive 421 can be used to drive the longitudinal bracket assembly 42 to move and adjust the longitudinal height in a driving manner of a pneumatic cylinder, and the front and rear bracket drive 431 can drive The front and rear bracket assembly 43 is used to adjust the front and rear positions, and the transverse bracket driving member 441 can drive the transverse bracket assembly 44 to adjust the transverse position. This allows the imaging element 41 to achieve the advantage of multi-axis movement adjustment. In other words, even if the self-focusing module 411 fails, the user can also use manual adjustment to focus the imaging element 41, achieving the advantage of diversification. If the self-focusing module 411 is not faulty, a fully automatic design can be achieved. The user does not need to make additional manual adjustments, and can directly complete the automatic focusing purpose through the self-focusing module 411, which is convenient, fast, and accurate. (See the second and fifth figures)

Regarding step (c), while the packaging platform device 1 drives the material belt A to move, the electronic component B can be placed in the slot A1 of the material belt A and placed according to the direction defined by the manufacturer (see Figure 4).

Regarding step (d), when the packaging platform device 1 drives the material belt A to move under the imaging element 41, the imaging element 41 will take a picture of the electronic component B and generate a photo (see Figure 5).

In step (e), the aforementioned photo will be transmitted to the electronic component status judgment module 62 for judgment. The electronic component status judgment module 62 will compare the photo with the data stored in the storage module 61. For example, the electronic component B has an IC model, and the storage module 61 stores the IC model and correct direction information of the electronic component B. The photo taken by the camera element 41 shows that the IC model is present. At this time, the electronic component status judgment module 62 will This photo is compared with the information in the storage module 61. When the comparison result shows that the position of the IC model is opposite, it means that the placement angle of the electronic component B is incorrect. At this time, the electronic component state judgment module 62 immediately sends an error message to the stop module 63. The stop module 63 drives the packaging platform device 1 to stop the operation of the material belt A. Thereafter, the electronic component B with the wrong direction can be placed correctly, and then the packaging platform device 1 is started to perform subsequent operations. If the electronic component status judgment module 62 compares the status information such as dirty fonts, incorrect font appearance, font printing angle deviation, no electronic components, etc., it will still notify the stop module 63 to control the packaging platform device 1 to pause, and at the same time drive the warning device 8 to light or sound, effectively reminding the user of the on-site situation, so as to facilitate immediate replacement or diversion (see Figures 1, 6, and 7).

Regarding step (f), when the above problems are eliminated, the material tape A with the electronic components B will be combined with the sealing film C from the film roll element 51 through the packaging element 52, and finally the second roll element 3 will be rotated and stored by a driving element 31 for driving the second roll element 3 (see Figure 8).

Thus, the imaging element 41 can store the photo file in the storage module 61, and the user can use the screen 9 to view it immediately or play it back for viewing later, so as to make a complete picture record, which can be faster and more convenient to clarify the problem in the future.

In addition, it can also be used as a record of yield statistics. For example, when a complete material strip A has 500 slots A1, if the number of stops of the stop module 63 falls to 50, the storage module 61 will record the stop 50 times, and then the yield can be calculated to be 90% and the defective rate to be 10% and recorded. This statistical result is also convenient for users to manage in the future.

Please refer to the ninth figure, which is a schematic diagram of the resume of the preferred embodiment of the present invention. It can be clearly seen from the figure that when the user wants to view the resume of electronic component B, the reader D can be used to read the reading unit B1 on the electronic component B. The reader D can be a smart phone or a barcode reader, etc. After the reader D scans the reading unit B1, it loads the resume information of the electronic component B (production time, model, origin, production factory, or batch number, etc.) according to the link provided by the reading unit B1. The loading source comes from the resume module 7.

Please refer to FIG. 10, which is a schematic diagram of a robot arm of another preferred embodiment of the present invention. It can be clearly seen from the figure that a first robot arm E is provided on the packaging platform device 1 and located between the first belt member 2 and the camera device 4, and a second robot arm F is provided on the packaging platform device 1 and located on one side of the camera device 4. It can be seen that the present invention can be packaged in a fully automatic manner, and the work of the first robot arm E can be to wait for The packaged electronic components are grabbed and carried to the slots of the material belt, and the work of the second robot arm F is to grab the electronic components with problems in the slots after the electronic component status judgment module notifies the stop module to stop. For example, the electronic components with unclear fonts are grabbed and taken to the side for recycling, and then an electronic component is added. The camera element 41 re-photographs and re-compared and judged through the electronic component status judgment module, thus achieving the advantage of full automation.

Please refer to the eleventh figure, which is a schematic diagram of another preferred embodiment of the present invention. It can be clearly seen from the figure that the present embodiment is different from the above embodiments in that the processing device 6 of the present embodiment is a circuit substrate and is disposed on the imaging element 41. In this way, the processing device 6 and the imaging element 4 1 are combined into one, which effectively reduces the overall volume of the intelligent packaging machine of the present case, and does not occupy too much space because of the processing device 6.

Therefore, the structure and method of the intelligent packaging machine of the present invention are the key technologies that can improve usage:

First, the advantage of automatically identifying the status of electronic component B placed on the material strip A can be achieved by using the imaging element 41 of the imaging device 4 in combination with the storage module 61 and the electronic component status judgment module 62 in the processing device 6.

Second, the self-focusing module 411 enables the imaging element 41 to have the advantage of automatically performing focus correction.

Third, this case can make a yield statistics for the production process, so that users can know the yield of this batch of electronic components B and then immediately improve its situation.

Fourth, the camera element 41 can store the photo file in the storage module 61, which can be used by the user to view it immediately or replay it later on the screen 9 to make a complete picture record, which can be faster and more convenient to clarify the problem in the future.

Fifth, through the resume module 7, the user can quickly learn the production time, model, origin, production factory, or batch number of this batch of electronic parts B, and accurately grasp the source.

Sixth, the luminous or audible design of the warning device 8 can effectively remind the user of the on-site situation, making it easier to make immediate changes or changes.

Seventh, through the design of the first robot arm E and the second robot arm F, the advantage of full automation is achieved.

Eighth, through the film roll component 51 and the packaging component 52 of the packaging device 5, the advantage of automated packaging is achieved.

Ninth, this case uses material belt A for storage, which can have better storage space compared with the working tray (Tray). For the same number of slots A1, the volume of the material belt will be smaller than that of the working tray (Tray), making it easier to store.
