Description

Technical Field

[0001] This utility model relates to the technical field of circuit board positioning devices, specifically a positioning device for printed circuit board processing. Background Technology

[0002] When processing circuit boards, positioning devices are needed to fix them in place to facilitate processing.

[0003] Chinese patent disclosure (CN220292269U) discloses a positioning device for printed circuit board processing. The device includes a base on which two sets of first clamping plates and two sets of second clamping plates are slidably mounted. The first clamping plates and the second clamping plates move towards each other, with their directions of movement perpendicular. Through the design of the two sets of first clamping plates, the two sets of second clamping plates, and two sets of driving mechanisms, one driving mechanism drives the two sets of first clamping plates to move towards each other, and the other driving mechanism drives the two sets of second clamping plates to move towards each other. This allows the space enclosed by the two sets of first and second clamping plates to continuously change, and can be adjusted arbitrarily according to the size of the circuit board, making it more versatile and capable of positioning and processing circuit boards of various sizes. Furthermore, this device only requires rotating two screws to achieve circuit board positioning, making operation simple and convenient, thereby improving the processing efficiency of circuit boards.

[0004] However, it still has the following drawbacks: the device clamps the circuit board through the first and second drive mechanisms, but it is not convenient to flip the circuit board or process the back side of the circuit board. Therefore, we propose a positioning device for printed circuit board processing to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for printed circuit board processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for printed circuit board processing, comprising a mounting base, wherein a positioning device is provided on the mounting base, and the positioning device includes a clamping part;

[0007] The clamping part includes a first motor, a support plate and a second motor. The bottom surface of the first motor is fixedly connected to the top surface of the support plate on the left side, and a bracket is fixedly connected to the bottom surface of the second motor.

[0008] A support is provided above the mounting base;

[0009] The support includes a limiting rod, the outer surface of which has a sliding groove, and an mounting plate is slidably sleeved on the outer surface of the limiting rod.

[0010] A further improvement is that the clamping part further includes a first gear, a rack, a slide rod, a slider, a second gear, a third gear, a clamping plate, a rotating shaft, a limiting cylinder, and a connecting rod. The outer surface of the rotating shaft is rotatably connected to the outer surface of the support plate through a bearing seat. The outer surface of the rotating shaft is fixedly connected to the outer surface of the clamping plate. A through groove is provided on the top surface of the mounting base. The outer surface of the slide rod is fixedly connected to the inner wall of the mounting base. The slider is slidably sleeved on the outer surface of the slide rod. The bottom surface of the support plate is fixedly connected to the top surface of the slider. By setting the support rod, rotating shaft, clamping plate, slide rod, and slider, the clamping plate is used to clamp the circuit board.

[0011] A further improvement is that the first gear is fixedly sleeved on the outer surface of the output shaft of the second motor, the top surfaces of the two racks are respectively fixedly connected to the bottom surfaces of the two sliders, and the outer surface of the bracket is fixedly connected to the inner wall of the mounting base. By setting the second motor, the first gear and the racks, after the second motor is started, it drives the two racks to move, so that the two sliders move closer to each other, and the clamping plate clamps the circuit board.

[0012] A further improvement is that the third gear is fixedly sleeved on the outer surface of the first motor output shaft, and the second gear is fixedly sleeved on the outer surface of the left rotating shaft. By setting the first motor, the second gear, and the third gear, after the first motor is started, the clamping plate and the circuit board are driven to flip, which facilitates the processing of the other side of the circuit board.

[0013] A further improvement is that the limiting cylinder is slidably sleeved on the outer surface of the connecting rod, and the outer surface of the limiting cylinder and the outer surface of the connecting rod are respectively fixedly connected to the outer surfaces of the two clamping plates. By setting the limiting cylinder and the connecting rod, the two clamping plates can rotate simultaneously, so that the inner walls of the two clamping plates always correspond to each other, which facilitates the clamping and flipping of the circuit board.

[0014] A further improvement is that the support part also includes a hydraulic rod, a pad, and an elastic element. The top surface of the middle mounting plate is fixedly connected to the bottom surface of the pad, the outer surface of the elastic element is fixedly connected to the outer surface of the mounting plate, and the outer surface of the outer mounting plate is pressed against the outer surface of the support plate. By setting the elastic element, the mounting plate, and the pad, the mounting plate is arranged in a dispersed manner using elastic clamps, and the pad is used to support the circuit board.

[0015] A further improvement is that the outer surface of the bottom end of the hydraulic rod is fixedly inserted through the top surface of the mounting base and extends into the interior of the mounting base. The output rod of the hydraulic rod is fixedly sleeved on the outer surface of the limiting rod. By setting the hydraulic rod, it is convenient to control the up and down movement of the limiting rod, the mounting plate and the pad, to support the circuit board, and to facilitate the flipping of the circuit board.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This positioning device for printed circuit board processing, by setting up a first motor, a bracket, a second motor, a first gear, a rack, a slide bar, a slider, a support plate, a second gear, a third gear, a clamping plate, and a rotating shaft, can drive the two clamping plates to move closer together, thereby clamping the circuit board. Activating the first motor drives the left rotating shaft to rotate, thus controlling the circuit board to flip, facilitating processing on both sides of the circuit board. By setting up a limiting cylinder and a connecting rod, the left clamping plate can drive the right clamping plate to flip together, ensuring that the inner walls of the two clamping plates always correspond, facilitating the clamping of the circuit board. By setting up a hydraulic rod, a limiting rod, a pad, a mounting plate, and an elastic element, the extension of the hydraulic rod can be controlled, allowing the pad to support the circuit board upwards. The elastic element allows multiple mounting plates to be distributed, improving the support effect on the circuit board. Attached Figure Description
