The X-ray component counting mechanism includes a second frame, a second tray conveyor belt, an X-ray component counter, and a first tray positioning member. The second tray conveyor belt and the X-ray component counter are both installed within the second frame. The first tray positioning member is installed on the second tray conveyor belt, and the X-ray component counter is located above the second tray conveyor belt. The X-ray component counter is used for component counting; a discharging and labeling component. After adopting the above technical solution, this utility model can save labor and improve efficiency.

[0003] In the prior art including the above patent, in the process of component counting production, the existing tray needs to be placed on the transmission device, and then the tray is clamped by a mechanical gripper to the labeling area and labeled on the end face of the tray. Before labeling, the labeling area of the tray needs to be cleaned. The existing labeling method usually conducts centralized cleaning. In a semi-closed production workshop, it is inevitable that dust and other impurities adhere to the labeling area of the tray during the transfer process. The dust and other impurities will block the key information on the label, making it difficult for the barcode scanning device or manual identification, reducing work efficiency, and even potentially causing production accidents due to incorrect information reading. Moreover, if dust enters the interior of the component counter, it will adhere to key components such as sensors and lenses, affecting the accuracy and stability of the device, and further affecting the accuracy of the component counting result. Summary of the Invention

[0010] Preferably, a reciprocating activity hole matching the plug rod is formed on each socket. A square through hole matching the square guide block is formed on each square guide seat.

[0011] Preferably, each guide rail groove includes an inclined groove formed on the blocking ring. An arc-shaped groove is arranged on one side of the inclined groove. The plurality of sponge cleaning blocks are distributed in a circular array.

[0012] S1: First, by starting the transfer device body, the gripper body installed at the bottom of the electric clamping mechanism moves towards the tray body and clamps the tray body. S2: During the movement of the fixed partition, the bottom of the blocking ring contacts the top of the tray body.

The automated cleaning process does not require manual operation, avoiding the problem of incomplete cleaning caused by human negligence, improving the production efficiency at the same time. By directly driving the sponge cleaning blocks to rotate with the downward force of the transfer device, there is no need to additionally set up a motor or a transmission device, simplifying the device structure, reducing the manufacturing cost. At the same time, the downward force of the transfer device is usually controlled by a precision mechanical structure. After being converted into a rotational force, the rotation speed and strength of the cleaning blocks are more stable. BRIEF DESCRIPTION OF THE DRAWINGS
