[0002] When repairing circuit boards on CNC machine tools, they must be placed on a conveyor and transported to the machine's frame, where a robotic arm can remove and install the chip. However, before the robotic arm removes the circuit board, a clamping plate is designed to secure the CNC machine tray. The bottom of the conveyor also provides support. However, the elasticity of the conveyor belt can affect the stability and accuracy of the support.

[0003] After searching, a Chinese patent document (application publication number CN108788896A) describes a CNC machine tool tray support device, comprising a base, a housing fixed to the upper surface of the base, a maintenance device mounted on the top inner wall of the housing, an infrared transmitter disposed on one side of the lower surface of the maintenance device, a control box mounted on one side wall of the base, brackets symmetrically disposed on both sides of the upper surface of the base, a conveyor belt connected between the two brackets, a tray placed on the conveyor belt, an infrared receiver mounted on one side of the upper surface of the tray, two mounting plates welded to the upper surface of the base, and the two mounting plates are located on both sides of the conveyor belt, a fixed plate is fixed between the two mounting plates, and a first rotating shaft is rotatably mounted between the two mounting plates. The present invention has a simple structure and novel design. It uses a motor to support and clamp the tray, greatly improving the accuracy of the robot arm during operation. Before the robot arm removes the circuit board, a clamping plate is designed to clamp and fix the CNC machine tool tray, and then the bottom is also supported under the conveyor. However, the elasticity of the conveyor belt affects the stability and accuracy of the support. Utility Model Content
