Description
Technical Field
[0001] This utility model relates to the field of PCB circuit board testing technology, specifically a PCB circuit board fixing clamp device. Background Technology
[0002] A PCB, also known as a printed circuit board, is a base used for the electrical connection and mechanical support of electronic components. It forms conductive copper foil lines on an insulating substrate through processes such as printing and etching, realizing the electrical connection between electronic components and providing mechanical fixation and heat dissipation functions. When testing a PCB, a clamping device is required to fix the PCB. When fixing and testing a double-sided PCB, the double-sided PCB needs to be flipped over to facilitate testing on both sides.
[0003] A search revealed that patent application number 202320695611.7 discloses a clamping device for PCB circuit board testing, including a fixed base. The fixed base has two columns on its top, and each column is equipped with a flipping clamping mechanism. The flipping clamping mechanism includes a rotating shaft, one end of which is fixedly connected to a clamping seat. A support plate is fixedly connected to the bottom of one side surface of the clamping seat. A groove is formed on one side surface of the clamping seat, and a clamping screw is rotatably connected inside the groove. A clamping knob is fixedly connected to the top of the clamping screw, and a clamping nut seat is threaded onto the clamping screw.
[0004] Although the PCB board inspection fixture can flip the PCB board that is clamped and pressed against the fixed plate by rotating the rotating shaft, the PCB board will be subjected to torque when the rotating shaft of the PCB board inspection fixture rotates, which can easily lead to damage to the PCB board.
[0005] Therefore, we propose a PCB board fixing fixture device. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a PCB circuit board fixing clamp device, which solves the problem that the PCB circuit board is subjected to torque during rotation when the rotating shaft of the existing device rotates, which can easily lead to damage to the PCB circuit board.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a PCB circuit board fixing clamp device, including a base plate, wherein upright plates are fixedly installed on both the left and right sides of the top surface of the base plate;
[0008] The top of the upright plate is provided with a flipping assembly, and the flipping assembly is provided with two clamping assemblies for clamping the PCB circuit board. The flipping assembly is also provided with a spacing adjustment assembly for adjusting the distance between the two clamping assemblies.
[0009] The flipping assembly includes two connecting plates and two connecting rods. The two connecting plates are rotatably mounted on adjacent sides of the top surfaces of the two upright plates via bearing rings. The two ends of the two connecting rods are fixedly mounted on the side walls of adjacent sides of the two connecting plates. A first motor is fixedly mounted on the side wall at the top of the upright plate on the right side. The output end of the first motor passes through the side wall of the upright plate and is fixedly mounted in the middle of the side wall of the connecting plate on the right side.
[0010] Preferably, the spacing adjustment assembly includes two hydraulic rods, which are respectively fixedly installed in the middle of adjacent sides of two connecting plates. The output ends of the two hydraulic rods are fixedly mounted with slides. The middle of adjacent sides of the two slides is provided with a sliding groove. The interior of the two sliding grooves is provided with a clamping assembly. The clamping assembly and the clamping assembly can be moved by the hydraulic rods.
[0011] Preferably, limit rods are fixedly installed on the front and rear side walls of both slides. A limit collar that slides on the outer surface of the connecting rod is fixedly installed on the end of the limit rod away from the slide. The movement of the slide and the clamping assembly can be limited by the sliding of the limit collar on the surface of the connecting rod, so as to prevent the slide and the clamping assembly from shifting their positions during movement.
[0012] Preferably, the clamping assembly includes a second motor fixedly installed in the middle of the top surface of the slide block. The output end of the second motor is fixedly connected to a bidirectional threaded rod through the top surface of the slide block. The bottom end of the bidirectional threaded rod is rotatably installed on the bottom surface of the slide groove through a bearing ring. The second motor can drive the bidirectional threaded rod to rotate.
[0013] Preferably, both ends of the outer surface of the bidirectional threaded rod are threaded with sliders that are slidably fitted inside the groove. A clamping plate is fixedly installed on the side wall of the slider. When the bidirectional threaded rod rotates, it can drive the slider and the clamping plate to move along the inner wall of the groove, thereby clamping and fixing the PCB circuit board through the clamping plate.
[0014] Preferably, a control panel is fixedly installed on the side wall of the upright plate. The first motor, hydraulic rod and clamping assembly are all electrically connected to the control panel. The operation of the first motor, hydraulic rod and clamping assembly can be controlled through the control panel. This is prior art and will not be described in detail here.
[0015] This utility model provides a PCB circuit board fixing clamp device. It has the following beneficial effects:
[0016] 1. This PCB circuit board fixing clamp device can clamp and fix the PCB circuit board by the cooperation of the spacing adjustment component and the clamping component. Then, the first motor drives the right connecting plate to rotate 180°, which can simultaneously drive the connecting rod and the left connecting plate to rotate together, thereby flipping the PCB circuit board. It is simple and convenient to use. The connecting rod can avoid the PCB circuit board being subjected to torque during the flipping process, which can prevent the PCB circuit board from being damaged during the flipping process. It is beneficial to protect the PCB circuit board and solves the problem that the PCB circuit board is subjected to torque during the rotation of the rotating shaft of the existing device, which can easily lead to damage to the PCB circuit board.

The output end of the first motor 33 passes through the side wall of the upright plate 2 and is fixedly installed in the middle of the side wall of the connecting plate 31 on the right side. The PCB circuit board can be clamped and fixed by the cooperation of the spacing adjustment component 4 and the clamping component 45.

It is simple and convenient to use. The connecting rod 32 can avoid the PCB circuit board from being subjected to torque during the flipping process, which can avoid damage to the PCB circuit board during the flipping process and is beneficial to the protection of the PCB circuit board.
[0026] Example 2:
[0027] like Figure 1-4 As shown: Limiting rods 43 are fixedly installed on the front and rear side walls of the two slides 42. A limiting collar 44, which is slidably fitted on the outer surface of the connecting rod 32, is fixedly installed on the end of the limiting rod 43 away from the slide 42. The clamping assembly 45 includes a second motor 451 fixedly installed in the middle of the top surface of the slide 42. The output end of the second motor 451 passes through the top surface of the slide 42 and is fixedly connected to a bidirectional threaded rod 452. The bottom end of the bidirectional threaded rod 452 is rotatably installed on the bottom surface of the slide groove 421 through a bearing ring. Both ends of the outer surface of the bidirectional threaded rod 452 are threadedly fitted with sliders 453, which are slidably fitted inside the slide groove 421. A clamping plate 454 is fixedly installed on the side wall of the slider 453. The distance between the two clamping assemblies 45 can be adjusted by the distance adjustment assembly 4.

[0030] The working principle and usage process of this utility model: When using this PCB circuit board fixing clamp device, the PCB circuit board is placed between two slide blocks 42. Then, the hydraulic rod 41 is activated to push the two slide blocks 42 to move towards the side closer to the PCB circuit board until the two slide blocks 42 move to both sides of the PCB circuit board. Then, the second motor 451 is activated to drive the bidirectional threaded rod 452 to rotate. Subsequently, the slider 453 and the clamping plate 454 move along the inner wall of the slide groove 421. Then, the clamping plate 454 clamps and fixes the PCB circuit board, so that the top surface of the PCB circuit board can be inspected. When it is necessary to flip the PCB circuit board, the first motor 33 is activated to drive the right connecting plate 31 to rotate. Then, the right connecting plate 31 drives the two connecting rods 32 and the left connecting plate 31 to rotate 180° together. This can flip the spacing adjustment component 4, the clamping component 45 and the PCB circuit board, so that the PCB circuit board can be flipped.
