Description

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) joining part and an apparatus used for the finishing method.

[0002]

2. Description of the Related Art Conventionally, when there is a burr on an FRP joint part, 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 body to butt them together, but at that time it is necessary to hold them with a jig and to position them when setting the jig. 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 a 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 perform the finishing process in a continuous process using a robot. However, the robot is used to operate the water jet and the polishing machine. In this case, 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, it is an object of the present invention to provide a finishing method and a device used therefor, which can perform both cutting and polishing operations in a single step in order using a robot.

[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. Fiber reinforced synthetic resin parts with burrs 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 stay. 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. According to the method, a turntable for rotating and stopping at a predetermined angle, a receiving jig for setting a workpiece fixed on the turntable, and a first rotation stop position of the turntable are controlled. And a rough cutting station consisting of a robot and a water jet operated by the robot,
The turntable is located at the second rotation stop position, and has a controlled robot and a polishing station including a polishing machine operated by the robot. The turntable is rotated to sequentially move the workpieces on the receiving jig. It can be efficiently carried out by the finishing device for the FRP joint component which is configured so as to stop moving and be positioned. In the present invention, in order to control the robot, not only the method of teaching based on the dimensions of the jig but also the method of controlling by sensing and feeding back the wall surface of the product can be adopted. Here, as a typical example of the FRP product to which the method of the present invention is applied, there 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 the predetermined cutting and polishing work can be sequentially performed by a robot controlled such that the jig is taught in advance.
