[0002] Circuit board processing is a batch manufacturing process, when the circuit board completes all processing in a process, it is usually temporarily placed on the stacking device, and after the batch of circuit boards are processed or the stacking device is loaded, the circuit boards on the stacking device are sent to the next station for processing.

[0003] The Chinese patent with publication number CN220974965U discloses a PCB printed circuit board stacking device, which comprises a placing frame, the inner wall bottom of the placing frame is fixedly connected with guide rods on both sides, the guide rods are slidingly connected with a supporting plate, a placing groove is formed on the surface of the placing frame, the bottom of the supporting plate is fixedly connected with a limiting device, the supporting plate is connected with the guide rods through the limiting device, the bottom of the supporting plate is provided with a pull ring, the bottom of the placing frame is provided with the guide rods to install the supporting plate, the supporting plate slides with the guide rods to improve the motion stability of the supporting plate, the bottom of the supporting plate is provided with the limiting device, the limiting device is connected with the guide rods to fix the position of the supporting plate, when the position of the supporting plate needs to be adjusted, the pull ring below the supporting plate is pulled down to move, the limiting device is pulled through the traction rope to adjust the limiting device, which is convenient for the staff to adjust.

[0004] However, in actual use, when the limiting device is released from the limiting of the supporting plate by pulling the pull ring, one hand needs to pull the pull ring and the other hand needs to hold the supporting plate, otherwise, the supporting plate will tend to drop due to its own weight, and the drop of the supporting plate will shorten the distance between the supporting plate and the pull ring, causing the straight traction rope to become loose, and the loosening of the traction rope will cause the limiting device to be inserted into the card slot driven by the spring, thereby causing the supporting plate to be stuck, resulting in incorrect adjustment of the position of the supporting plate.

[0012] 2. The installation of the control unit enables the user to control the position of the limiting plate by the control unit when the height of the supporting plate needs to be reduced, so as to avoid the automatic insertion of the limiting plate into the slot due to the driving of the spring, and after the height is adjusted to the position, the control unit is released to limit the limiting plate, so that the limiting plate can be automatically inserted into the corresponding slot, which is simple and convenient to use and saves manpower.

[0019] The utility model further sets up: the end of control panel side wall is made into inclined plane.

[0020] The principle and effect of the technical scheme are as follows: the setting of the inclined plane enables the limiting plate to trend away from the control panel by abutting and pressing the inclined plane, thereby spontaneously giving way to the limiting plate, thereby saving manpower, enabling the control unit to be completed without manpower control when limiting the limiting unit, simplifying the operation and improving the efficiency.

[0021] The utility model further sets up: the bottom surface of the supporting plate is fixed with the U-shaped guide slide frame, and the limiting plate is slidingly fitted in the guide slide frame.

[0022] The principle and effect of the technical scheme are as follows: the setting of the guide slide frame can guide and limit the sliding of the limiting plate, and share the gravity borne by the limiting plate in the vertical direction, thereby reducing the pressure borne by the connecting plate.

[0023] The utility model further sets up: the periphery of the bottom of the placing frame is provided with universal wheels.

[0024] The principle and effect of the technical scheme are as follows: the setting of the universal wheels enables the placing frame to be moved to the next processing procedure by the pushing mode without carrying, thereby being more flexible to use. BRIEF DESCRIPTION OF DRAWINGS
