Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a clamp for circuit board processing. Background Art

[0002] With the rapid development of electronic products, people's demand for electronic products is also increasing. In the production process of electronic products, the main technology lies in the processing of circuit boards. The names of circuit boards are: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. In the process of processing and production, circuit boards need to be processed in different processes, so special fixtures are needed to fix the circuit boards for easy work;

[0003] Most of the existing circuit board processing fixtures use cylinders to drive clamping plates to clamp the circuit boards. Since the stroke parameters of the cylinders are mostly set as fixed parameters, when the sizes of the circuit boards are different, if the cylinder parameters are not adjusted in time, the clamping plates may easily squeeze and damage the circuit boards. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a clamp for processing a circuit board.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamp for processing a circuit board, comprising a processing table and a PCB board body, a base is fixedly arranged on the processing table, a positioning frame is fixedly arranged on the upper end of the base, the PCB board body is placed on the base, and one end of the PCB board body is limited by the positioning frame, a positioning plate is fixedly arranged on the upper end of the base, a fixing seat is fixedly arranged in the middle part of the positioning plate, and positioning seats are fixedly arranged at both ends of the positioning plate, a spring is arranged inside the positioning seat, a support rod is fixedly arranged at one end of the spring, a clamping block for limiting the other end of the PCB board body is arranged at one end of the support rod, a screw is arranged on the fixing seat, the screw is threadedly connected to the fixing seat, and an anti-slip seat contacting the clamping block is arranged at one end of the screw.

[0008] Furthermore, the improvement of the utility model is that the positioning plate is fixed to the upper end of the base by screws.

[0009] In order to facilitate the operation of the screw rod, the utility model has the following improvements: a toggle block is provided at the outer end of the screw rod.

[0010] In order to improve the stability of the screw rod when in use, the utility model has the following improvements: a limiting sleeve penetrated by the screw rod is provided on one side of the base, a plurality of damping blocks are provided on the inner wall of the limiting sleeve, and the damping blocks contact the screw rod.

[0011] Furthermore, the present invention is improved in that the damping block is made of rubber.

[0012] Furthermore, the present invention is improved in that the anti-slip seat is provided with a plurality of anti-slip grooves.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a clamp for processing a circuit board, which has the following beneficial effects:

[0015] The circuit board processing fixture presses the other end of the PCB body. Since the upper end of the clamping block is an inclined surface and the bottom end of the clamping block is an arc, the clamping block can drive the support rod to compress the spring. At this time, the elastic force of the spring can enable the clamping block to provide a clamping and positioning effect for the PCB body, so that the PCB body can be easily loaded.

[0016] By rotating the screw, the anti-slip seat can contact the clamping block through the action of the threaded structure. As the screw continues to exert force, the friction between the clamping block and the PCB board body can firmly clamp the PCB board body on the base. When the sizes of the circuit boards are different, it is not easy for the clamping plate to squeeze and damage the PCB board body, which can reduce the limitations of this structure when used.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In this embodiment, the PCB body 4 is taken (the PCB body 4 in the attached figure is of the maximum size, that is, the width of the PCB body 4 will not be larger than the internal size of the positioning frame 3), one end of the PCB body 4 is made to contact the positioning frame 3, and then the other end of the PCB body 4 is pressed. Since the upper end of the clamping block 5 is an inclined surface and the bottom end of the clamping block 5 is an arc, the clamping block 5 can drive the support rod 9 to compress the spring. At this time, the elastic force of the spring can enable the clamping block 5 to provide a clamping and positioning effect for the PCB body 4. Further rotation of the screw rod 10 can make the anti-slip seat 12 contact the clamping block 5 through the effect of the threaded structure. As the screw rod 10 continues to exert force, the friction between the clamping block 5 and the PCB body 4 can firmly clamp the PCB body 4 on the base 2. When the sizes of the circuit boards are different, it is not easy for the clamping plate to squeeze and damage the PCB body 4, which can reduce the limitations of this structure when used.

[0026] In this embodiment, the positioning plate 7 is fixed to the upper end of the base 2 by screws, and the screw fixing method has the advantage of convenient assembly.

[0027] In this embodiment, a toggle block is provided at the outer end of the screw rod 10 .

[0028] In this embodiment, a limiting sleeve 13 penetrated by the screw 10 is provided on one side of the base 2, and a plurality of damping blocks 6 are provided on the inner wall of the limiting sleeve 13. The damping blocks 6 contact the screw 10, and the damping blocks 6 are made of rubber. The plurality of damping blocks 6 can prevent the screw 10 from rotating easily after being subjected to force, thereby improving the stability of the screw 10 during use.

[0029] Furthermore, the anti-slip seat 12 is provided with a plurality of anti-slip grooves, which can increase the friction between the anti-slip seat 12 and the clamping block 5, and can further improve the stability of the screw rod 10 when in use.
