After a while, this creation can hold the sandpaper firmly by moving the clamping plate closer to the shell, so that when the robot arm moves away from this creation, it can tear the sandpaper against it almost vertically to ensure each time When the robot arm replaces the sandpaper, it can completely replace the sandpaper.

Description

Sandpaper replacement device

This creation relates to a device for replacing consumables of a grinder, especially a device for replacing sandpaper on a robot arm.

Grinding metal plates is a very common machining process in the field of machining. Among them, in order to improve the efficiency of grinding, the processing methods of the prior art are mostly performed by using a robot arm; more precisely, a mechanical arm With respect to the abrasive part rotating relative to the robotic arm, sandpaper is detachably connected to the end of the abrasive part. When the abrasive part starts to rotate, the sandpaper will rotate with the abrasive part, and then the robotic arm will move the sanding paper close to the object to be ground. Surface, so as to achieve the effect of grinding the surface of the object; and because the sandpaper is a consumable item, after using it for a period of time, it will gradually lose the sanding effect, so users need to replace it with a new sandpaper Can continue to use.

Please refer to FIG. 9. In the prior art sandpaper replacement device, the sandpaper replacement operation on the robot arm is performed through a clamp head 91 that can be opened and closed. More precisely, when the robot arm needs to be replaced When the sandpaper 92 is moved to the periphery of the gripping head 91, the sandpaper 92 mounted on the abrasive member 93 is brought close to the gripping head 91, and then the gripping head 91 is closed up and down and the sandpaper 92 is protruded from the grinding The part of the part 93, then the robot arm is far away from the gripping head 91. Since the sandpaper 92 is clamped in the gripping head 91, the sandpaper 92 will be separated from the robot arm while the robotic arm is away from the gripping head 91.

However, in the prior art, such a sandpaper changing device using a clamping head 91, the clamping head 91 clamps the sandpaper 92 by means of upper and lower clamping, which results in insufficient stability; more precisely, the sandpaper 92 is subject to After clamping, when the robotic arm starts to move away from the gripping head 91 and separates the sandpaper 92 from the abrasive member 93 by pulling force, the gripping head 91 will not hold the sandpaper 92 firmly, so that the sandpaper 92 will be held by the gripper. The head 91 is loosened, causing the replacement of the sandpaper 92 to be incomplete and not being able to be separated from the abrasive member 93. The user must manually remove the sandpaper 92 from the abrasive member 93 before the subsequent processing process can be performed. Therefore, the prior art sandpaper replacement device has its defects.

In view of the shortcomings and deficiencies of the prior art, the present invention provides a sandpaper replacement device, which achieves a more stable clamping purpose through a clamping plate disposed vertically.

On one side, the power device can drive the clamping plate to move horizontally with respect to the power device, so that an inner side surface of the clamping plate and a side wall surface of the housing are selectively brought closer or farther apart.

The advantage of this creation is that the holding plate for holding the sandpaper is arranged on the housing in a vertical manner. Therefore, when the robotic arm is close to the work to replace the sandpaper, it will tear the direction of the sandpaper. During the tearing process, the sandpaper is almost parallel to the moving direction of the robot arm, thereby achieving the maximum tearing force. Compared with the prior art, the sandpaper is held horizontally, and the robot arm is tilted upward. In the state where the sandpaper and the robot arm are not completely separated due to the tearing of the moving method, the tearing direction of this creation can ensure that each time the robot arm tears the sandpaper, the sandpaper and the robot arm can be completely separated, thereby achieving the effective replacement of the sandpaper. purpose.
