Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a finishing method for removing burrs of a fiber-reinforced synthetic resin (hereinafter referred to as FRP) joined part and an apparatus used therefor.

[0002]

2. Description of the Related Art Conventionally, when there is a burr on an FRP joint component, it is necessary to remove the burr as a finishing process because it protrudes outward at the joint. In addition, when joining hollow bodies, an adhesive is placed on the joint end surface of the half-divided body, but they are butt-joined and joined together. Although it is proposed to provide an extra flange portion on the outer periphery of the joint portion, it is necessary to cut this flange portion after joining. In such a case, it is recommended to use a water jet as the cutting means, but it is necessary to polish and finish the rough burr portion remaining after cutting, which is performed in a separate process.

[0003]

By the way, in order to save labor, it is proposed to carry out the finishing process in a continuous process by using a robot. However, when the robot is used to operate a water jet and a polishing machine. , It is necessary to teach each robot in advance to the jig for setting the work, and there is a problem in maintaining accuracy. Therefore,
The present invention uses a robot to perform both cutting and polishing operations.
An object of the present invention is to provide a finishing method that can be performed in order in steps and an apparatus used for the finishing method.

[0004]

According to the present invention, a receiving jig for setting a work on a turntable is fixed, and the work is sequentially moved and positioned by stopping the rotation of the turntable. It was made paying attention to the fact that it is easy to control, including teaching, and that it is possible to automatically finish the work by setting the work once in the jig. And a step of setting a work on a receiving jig on a turntable, rotating the turntable by a predetermined angle, sending the jig to a water jet station, and operating the water by a controlled robot. Roughly cutting the work with a jet, and further rotating the turntable by a predetermined angle to finish the polishing Sent to ® down, by grinding machine operated by a robot in finishing method become more FRP bonding part and a step of polishing the rough cuts. The above method includes a turntable that rotates / stops at a predetermined angle, a receiving jig for setting a workpiece fixed on the turntable, and a first rotation stop position of the turntable that is controlled. And a water jet station including a water jet operated by the robot, and a polishing finishing station including a controlled robot and a polishing machine operated by the robot at a second rotation stop position of the turntable. And an FR which is configured to rotate the turntable and stop and sequentially move the work on the receiving jig.
It can be efficiently carried out by a finishing device for P-bonded parts. In the present invention, in order to control the robot, not only the method of teaching based on the dimension of the jig but also the method of controlling by sensing and feeding back the wall surface of the product can be adopted. Here, F to which the method of the present invention is applied
A typical example of the RP product is a hollow body such as an automobile spoiler generally manufactured by SMC molding.

[0005]

In the present invention, the work is set on the receiving jig on the turntable, and the turntable is rotated by a predetermined angle.
When stopped, the robot is positioned at a preset cutting and polishing work position, and a predetermined cutting and polishing work can be sequentially performed by a robot controlled such that the jig is previously taught.

The present invention will be described in detail below with reference to specific examples shown in the accompanying drawings.

1 and 2 are plan views showing the entire upper half body and lower half body of an automobile spoiler S to which the present invention is applied, in which a flange portion 11 of the upper half body 1 has a central portion thereof. Positioning recesses 12 are provided on both sides of the section. On the other hand, the lower half-split body 2 is formed with a flange portion 21 on the entire circumference of the end face abutting against the upper half-split body 1, and positioning recesses 22 are provided on the central portion and both sides thereof.

FIG. 4 is a cross-sectional view of an adhesive jig for joining the upper and lower half halves of FIGS. 1 and 2, which shows an upper and lower heating block 4 for sandwiching the upper and lower flange portions 11 and 21 and pressing the peripheral edge of the flange portion. It is formed from 4 '. FIG. 3 is a partial cross-sectional view of the hollow body joined by the bonding jig of FIG. 5 as shown in FIG. 1. The upper and lower halves 1 and 2 are 2 mm thick flange portions horizontally projected from the abutting surface and the outer periphery thereof. 11 and 21 are abutted and adhered to each other via the adhesive layer 3.
On the rear surface of the flange portion 21 of the lower half-split body 2, a width of 0.8 mm extending along the outer edge corresponding to a cutting line L2 set at an interval of 1 to 1.5 mm from the finishing line L1 and a bottom portion of about 0.5R. V-shaped groove 24 is formed. In the FRP product thus joined by using the flange portions 11 and 21, the flange portions 11 and 21 are cut by the finishing device described below, and the remaining rough burrs are removed by polishing.

As shown in FIG. 5, the finishing apparatus according to the present invention includes a turntable 5 which can be rotated and stopped every 120 degrees. The turntable 5 is divided into three at 120 degrees, and a receiving jig 6 is fixed to each section so that a work can be set. This receiving jig 6 is, as shown in FIG.
The support legs 61 are arranged along the outer shape of the above, and as shown in FIG. 7, the upper half-split body 1 is sucked and fixed downward by the suction pad 62 at the center portion.

The first rotation stop position of the turntable is the water jet section 7 formed by the water jet.
And is composed of a pair of robots 71 and 72 that are taught based on the dimensions of the receiving jig 6 and a water jet 73 with a diameter of 0.1 to 0.4 mm that is operated by the robots. The left and right halves of the formed work W are in charge of each, and the flange portions 11 and 21 are cut along the cutting line L2 as shown in FIG. 3 (see FIG. 8). The robot may also perform distance measurement at all times by light irradiation from the sensor S, and the arithmetic unit M may feedback-control a robot arm (not shown) that operates the water jet 73.

The second rotation stop position of the turntable is the polishing finishing station 8, and a pair of robots 81 are set based on the size of the receiving jig 5.
82 and a polishing machine 83 operated by the robot, which are in charge of the left and right halves of the symmetrical work W, respectively, and are arranged along the finishing line L1 as shown in FIG.
The remaining rough burrs 23 of 1 and 21 are removed by polishing. Specifically, as shown in FIG. 9, a polishing machine 83
Is composed of a polishing paper 87 which is stretched between a main roller 85 having a sponge which is rotated by an air motor 84 wound around the surface thereof and an auxiliary roller 86 which is confrontably contracted via an air cylinder 88, and is rougher than the paper 87. Bali 23
