Description

Technical Field

[0001] This invention relates to the field of circuit board conveying devices, and more particularly to a conveying and positioning device for circuit board production. Background Technology

[0002] Circuit board conveying devices are core equipment used for automated PCB transfer in electronic manufacturing. Their core function is to achieve precise and efficient transfer of PCBs between various processes on the production line through mechanical structures and control systems.

[0003] A search revealed a utility model patent with application number 202321856562.7, entitled "A Conveying Device for Circuit Board Production That Is Easy to Install." This patented device drives two sets of electric push rods to move push plates in opposite directions, placing the circuit board on a conveyor belt. One end of a first motor drives the conveyor belt, which is fitted onto the outer wall of a pulley, to rotate. Simultaneously, the limiting block at the lower end of the push plate slides inside the limiting groove, allowing for the conveying of circuit boards of different sizes. This avoids the limitation of being only applicable to conveying circuit boards of fixed sizes, thus improving the applicability of circuit board conveying. The structure is simple.

[0004] However, this patented device cannot install components on both sides of the circuit board at once, which greatly increases the number of steps in the circuit board production process and affects the efficiency of the device in circuit board production. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a transfer and positioning device for circuit board production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A conveying and positioning device for circuit board production includes a support frame with slots on both sides. A circular plate is rotatably connected to one end of the inner wall of the circumferential side of the slot. At least two lifting blocks are slidably connected to one side of the circular plate. At least three rotating shafts are rotatably connected to one side of the lifting blocks. Rollers are fixedly connected to the circumferential side of the rotating shafts. A conveyor belt is meshed between the circumferential sides of the rollers. A motor aligned with the rotating shafts is fixedly connected to one side of the lifting blocks. The output shaft of the motor is fixedly connected to one end of the rotating shaft.

[0007] Preferably, a lifting groove 2 is provided on one side of the circular plate, a motor 4 is fixedly connected to the top inner wall of the lifting groove 2, a lead screw 2 is fixedly connected to the output shaft of the motor 4, and the other end of the lead screw 2 is rotatably connected to the bottom inner wall of the lifting groove 2.

[0008] Preferably, the circumferential side of the lead screw two is threaded with at least two movable blocks aligned with the lifting block. The side of the movable block is slidably connected to the side of the lifting groove two, and the other side of the movable block is fixedly connected to one side of the lifting block.

[0009] Preferably, a motor five is fixedly connected to the inner wall of one side of the slot, a rotating shaft three is fixedly connected to the output shaft of the motor five, and the other end of the rotating shaft three is fixedly connected to one side of the circular plate. At least two lifting slots one are provided on one side of the support frame.

[0010] Preferably, at least three motors are uniformly fixedly connected to the inner wall of one side of the lifting trough, and the output shaft of the motor is fixedly connected to a lead screw, the other end of which is rotatably connected to the bottom of the lifting trough.

[0011] Preferably, at least two movable blocks are evenly threaded on the circumferential side of the lead screw, one side of the movable block is slidably connected to the inner wall of the lifting groove, and one side of the movable block is fixedly connected to a lifting plate.

[0012] Preferably, a motor is uniformly and fixedly connected between the two sides of the lifting plate, a rotating shaft is fixedly connected to the output shaft of the motor, a roller is fixedly connected to the circumferential side of the rotating shaft, and a conveyor belt is meshed between the circumferential sides of the roller.

[0013] Compared with the prior art, the present invention provides a conveying and positioning device for circuit board production, which has the following advantages: The device adjusts the distance between conveyor belts 1 and 2 by using a circular plate. Starting motor 3 drives a moving block, which in turn moves a lifting plate, which in turn moves roller 1. This allows the device to accommodate circuit boards of different sizes, expanding its applicability. Starting motor 1 then drives a rotating shaft, which in turn rotates roller 1, which in turn rotates conveyor belt 1. Motor 2 drives shaft 2 to rotate, which in turn drives roller 2 to rotate. Roller 2 drives conveyor belt 2 to rotate, and conveyor belts 1 and 2 move the circuit board to the processing point for processing. When the circuit board is between conveyor belts 2, motor 5 is started, which drives shaft 3 to rotate. Shaft 3 drives a circular plate to rotate, which in turn drives two sets of conveyor belts 2 to rotate. Conveyor belts 2 then drive the circuit board to rotate, allowing the circuit board to complete the installation of components on both sides at once. This helps prevent the inability to install components on both sides of the circuit board at once, which would greatly increase the number of steps in the circuit board production process and affect the efficiency of the equipment in circuit board production.
