Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board transfer, and in particular relates to a circuit board transfer box. Background Art

[0002] Printed circuit boards are important electronic components and are the carriers of electrical connections for electronic components. In circuit board processing, in order to facilitate the flow of circuit boards between various processes, transfer boxes are usually used to centrally store and transport circuit boards.

[0003] Chinese patent publication number CN218908176U discloses a circuit board transfer device, comprising a box and circuit boards. The box is provided with multiple layers of plug-in boards, which are embedded in the box. The top of the plug-in boards is provided with multiple equidistant and parallel slots for inserting circuit boards. The slots are used to insert circuit boards. Side ears are connected to the opposite side walls of the plug-in boards. The side walls of the box are provided with sliding openings corresponding to the side ears. The edges of the sliding openings are provided with limit assemblies. The circuit boards to be transferred are inserted into the slots on the plug-in boards one by one. When the plug-in boards are fully inserted, the plug-in boards are placed into the box. Multiple plug-in boards can be placed in the same box, allowing more circuit boards to be transferred at a time. The plug-in boards can also be removed through the side ears in the sliding openings, avoiding the situation where there are no gaps inside the box and it is difficult to remove the boards. The stopper lever is rotated, and the stopper lever blocks the edge of the sliding opening, limiting the side ears and preventing them from sliding out of the sliding opening. The provision of a damping shaft prevents the stopper lever from rotating at will.

[0004] However, in actual use, when multiple plug-in boards are stacked on each other and placed in the box, the upper plug-in boards are directly pressed against the circuit boards of the lower plug-in boards, and the circuit boards on the bottom layer need to bear the overall weight of the upper body, which may cause the circuit boards to be crushed. Although the setting of the baffle can prevent the plug-in boards from leaving the box, it cannot fix the position of the plug-in boards. The plug-in boards can move up and down without leaving the box. That is, when transferring circuit boards, encountering bumps may cause some plug-in boards to shake and jump in the box, thereby causing damage to the circuit boards. In summary, the transfer box is prone to damage to the circuit boards when in use. Utility Model Content

[0005] The utility model is intended to provide a circuit board transfer box to solve the problem mentioned above that the prior art easily causes damage to the circuit board during use.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions: a circuit board transfer box, comprising

[0007] The box body has limit slots on both sides;

[0008] There are multiple plug-in boards, which are vertically placed in the box in sequence. The plug-in boards are spaced apart and have multiple slots, in which circuit boards are inserted;

[0009] The sliding mechanism includes two sliding units symmetrical about the plug-in plate. The sliding unit includes a slider, a baffle, an elastic component, a brake plate and a driving component. The slider is fixed on the side wall of the plug-in plate, and the slider slides in cooperation with the limit groove. The baffle is fixed on the side of the slider away from the plug-in plate. The brake plate is slidably mounted on the slider, and the brake plate abuts against the outer wall of the box body. The elastic component is installed on the baffle, and the movable end of the elastic component is connected to the brake plate. The driving component is installed on the baffle and is used to drive the brake plate to slide along the slider.

[0010] The principle and effect of this technical solution:

[0011] 1. The arrangement of the box, plug-in boards, and slots allows multiple circuit boards to be inserted into the plug-in boards and placed in the box. The plug-in boards are limited by a sliding stop mechanism, so that the plug-in boards are subjected to a clamping force after being placed in the box. This clamping force supports the weight of the plug-in boards, thereby preventing the upper plug-in boards and circuit boards from crushing the circuits on the lower layer, and preventing the plug-in boards and circuit boards on the plug-in boards from jumping due to bumps during box transportation.

[0012] 2. By sliding the slider within the limit slot, the plugboard can only slide up and down after being placed in the box. Through the arrangement of the baffle, elastic component and brake plate, the brake plate can spontaneously press against the outer wall of the box under the elastic force of the elastic component, thereby providing vertical friction. After the plugboard is placed in the box, the weight of the plugboard can be distributed by this friction, thereby reducing or even eliminating the pressure of the upper plugboard on the lower circuit board. This friction also limits the plugboard from moving up and down along the box, thereby ensuring that the box remains stable even when encountering bumps during transit and transportation, and preventing damage to the circuit boards.

[0013] 3. By setting up the drive assembly, the position of the brake plate can be controlled by the drive assembly, thereby making it convenient for workers to insert the plug-in plate into the box or remove the plug-in plate from the box.

[0014] The utility model is further configured as follows: the elastic component includes a telescopic rod and a spring, a accommodating groove is opened on the side wall of the baffle, the telescopic rod is fixed in the accommodating groove, the movable end of the telescopic rod is fixed to the side of the brake plate away from the box body, the spring is sleeved on the telescopic rod and is located between the baffle and the brake plate.

[0015] The principle and effect of this technical solution: the setting of the telescopic rod and the spring enables the brake plate to slide stably along the slider while being spontaneously pressed against the outer wall of the box by the rebound force of the spring, thereby clamping and limiting the plug plate through the friction force with the box, and when the brake plate is driven away from the box by the driving component, the sliding of the brake plate can be made to give way by compressing the spring and the telescopic rod, thereby releasing the friction between the brake plate and the box, making the plug plate easy to disassemble and assemble, and the telescopic rod can not only guide and limit the brake plate, but also limit the spring, thereby ensuring the stable operation of the elastic component.

[0016] The utility model is further configured as follows: the driving assembly includes a driving plate, a driving rod and a rotating shaft. The driving plate has an inverted U-shape. The driving plate is slidably mounted on the end of the baffle away from the box body. The rotating shaft is fixed on the slider, and the middle part of the driving rod is rotatably mounted on the rotating shaft. One end of the driving rod is slidably hinged to the driving plate, and the other end of the driving rod is slidably hinged to the brake plate.

[0017] The principle and effect of this technical solution: through the arrangement of the driving rod, the rotating shaft and the driving plate, a crank slider mechanism is formed between the driving plate, the rotating shaft driving rod and the brake plate. By controlling the driving plate to approach the baffle, the driving rod can be rotated around the rotating shaft to drive the brake plate away from the outer wall of the box body, thereby releasing the pressure of the brake plate on the box body, and after releasing the external force, the brake plate can spontaneously approach the box body under the action of the rebound force of the spring, thereby driving the driving rod and the rotating shaft to reset.

[0018] The utility model is further configured as follows: an inserting rod is fixed on the side wall of the driving plate, and a clearance hole corresponding to the inserting rod is coaxially opened on the baffle plate and the sliding block.

[0019] The principle and effect of this technical solution: The setting of the insertion rod can guide and limit the driving plate, so that when the worker presses the driving plate, the driving plate can stably approach and move away from the baffle.

[0020] The utility model is further configured as follows: two driving rods are rotatably sleeved on the rotating shaft, and the two driving rods are symmetrical with respect to the sliding block.

[0021] The principle and effect of this technical solution: the two symmetrically arranged driving rods can make the driving force exerted on the brake plate more uniform, thereby making the movement of the brake plate more stable.

[0022] The utility model is further configured as follows: both sides of the bottom of the box body are provided with anti-slip protrusions.

[0023] The principle and effect of this technical solution: the setting of the anti-slip protrusions makes the box more stable during placement and transportation.

[0024] The utility model is further configured such that: the projection of the anti-slip protrusion on the horizontal plane is located on the inner side of the projection of the inner wall of the box on the horizontal plane.

[0025] The principle and effect of this technical solution: by arranging the anti-slip protrusion on the inner side of the inner wall of the box, when multiple boxes are stacked, the upper anti-slip protrusion can be inserted into the inside of the lower box, and the abutment between the anti-slip protrusion and the inner wall of the box can play a certain anti-dumping effect, thereby improving the stability of multiple boxes when stacked.
