Description

Technical Field

[0001] The utility model relates to the technical field of PCBA boards, and specifically relates to a transfer device for PCBA boards. Background Art

[0002] During the production and processing of circuit boards, after a certain production process is completed, it is necessary to batch-transfer the circuit boards to the next process. The existing processing method is to place the batch of circuit boards on a transfer cart. Usually, the circuit boards are stacked layer by layer. In this way, the horizontally stacked circuit boards are mutually extruded, which has an adverse effect on the quality of the circuit boards. Although there are some circuit board placement racks on the market, the vertical placement stability of the circuit boards is poor, and it is easy to have bumping phenomena. The circuit boards cannot be effectively protected. In addition, the gap between the circuit boards is small, and it is very difficult for workers to reach into the gap between the circuit boards, which increases the working difficulty.

[0003] According to a transfer device for circuit board production disclosed in Chinese Patent with the publication number "CN213705512U", it effectively solves the problems of inconvenient circuit board picking and placing, poor stability effect, and easy damage to the performance of the circuit board. It includes a base. A plurality of parallel through grooves are provided on the upper surface of the base. Baffles are fixed on the left and right sides of the upper surface of the base. Card slots are provided on the baffles in the groove length parallel direction of the parallel through grooves. A plurality of rotating shafts arranged in the front-rear direction are rotatably connected in the base. A horizontally arranged worm is rotatably connected to the front end of the base. A worm gear meshing with the worm is coaxially fixed on the rotating shaft. A cam and a disc are coaxially fixed on the rotating shaft. The cam and the disc are alternately arranged in sequence directly below the plurality of parallel through grooves. An arc groove is provided on the outer edge surface of the cam. The arc groove includes a semi-circular arc groove and a convex arc groove. An arc groove is provided on the outer edge surface of the disc. The structure of the utility model is ingenious, with low cost, good stability effect, and high safety factor.

[0004] However: Although this device can transfer the circuit boards inside the box, there is no anti-collision structure on the front of this device. Therefore, during the transfer process of this device, when it collides with other obstacles, the vibration generated by the collision may damage the circuit boards. Therefore, the safety of this device needs to be improved. Therefore, a transfer device for PCBA boards is proposed to solve the above-mentioned problems. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a transfer device for PCBA boards in view of the above-mentioned deficiencies in the prior art.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A transfer device for PCBA boards includes a box body, and a protection mechanism is arranged on the front surface of the box body;

[0008] The protection mechanism includes a horizontal sliding groove, a horizontal sliding block, a protection plate, a sliding rod, a fixing block, a damper, a sliding sleeve, a connecting rod, and a spring;

[0009] The horizontal sliding grooves are opened on the inner walls of the left and right sides of the box body. The horizontal sliding blocks are slidably connected inside the horizontal sliding grooves. The left and right sides of the protection plate are respectively fixedly connected to the two horizontal sliding blocks. The left and right ends of the sliding rod are respectively fixedly connected to the inner walls of the left and right sides of the box body. The fixing block is fixedly connected to the back surface of the protection plate. The front end of the damper is fixedly connected to the fixing block, and the rear end of the damper is fixedly connected to the middle of the sliding rod. By setting the horizontal sliding grooves, the forward and backward movement of the horizontal sliding blocks is limited.

[0010] Preferably, the sliding sleeve is slidably connected to the middle of the sliding rod, and the sliding sleeve is hinged to the fixing block through a connecting rod. By setting the sliding rod, the left and right movement of the sliding sleeve is limited.

[0011] Preferably, one end of the spring is fixedly connected to the sliding sleeve, and the other end of the spring far from the sliding sleeve is fixedly connected to the inner wall of the box body.

[0012] Preferably, a lifting mechanism is arranged inside the box body. The lifting mechanism includes five groups of vertical sliding grooves. The vertical sliding grooves are opened on the left and right sides of the inner wall of the box body. A support plate is slidably connected inside the vertical sliding grooves through sliders. By setting the support plate, the circuit board is supported.

[0013] Preferably, a motor is fixedly connected to the outer wall of the back surface of the box body. The front output end of the motor penetrates into the inside of the box body and is fixedly connected to a transmission shaft. Five cams are fixedly connected to the middle of the transmission shaft. The five cams are respectively slidably connected to the lower surfaces of the five support plates. By rotating the cams, the support plates are lifted.

[0014] Preferably, support legs are fixedly connected to the four corners of the bottom of the box body. Universal wheels are fixedly connected to the bottom ends of the support legs. A push handle is fixedly connected to the back surface of the box body.

[0015] Adopting the above technical solution, the utility model can bring the following beneficial effects:

[0016] 1. When a collision occurs on the front surface of the device, the protection plate will bear this impact first. Subsequently, the impact force generated by the impact drives the fixing block to move backward. The backward movement of the fixing block compresses the damper through cooperation with the sliding rod. During the compression of the damper, the impact force generated by the collision is dampened, thereby improving the safety of the device during the transportation of the circuit board.

[0017] 2. Start the motor to drive the transmission shaft to rotate. The rotation of the transmission shaft drives the simultaneous rotation of five cams, and simultaneously lifts five support plates. The upward movement of the five support plates drives the simultaneous upward movement of five circuit boards to the outside of the box, facilitating the staff to take the circuit boards.
