Description

Technical Field

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

[0002] The PCB board, namely the printed circuit board, also known as the printed wiring board, is the provider of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantages of using a circuit board are to greatly reduce wiring and assembly errors, improve the automation level and production labor rate. During the PCB board processing, before processing, it is necessary to support the non-processing surface of the PCB board. Currently, the PCB board is generally supported by a fixture.

[0003] In the prior art, most of the existing fixtures for PCB board processing are fixedly installed, and can only position a single PCB board, and cannot adapt to the placement of multi-specification PCB boards, so there are certain limitations. At the same time, after some fixtures for PCB board processing position the PCB board, it is easy for some parts to block the PCB board, thus affecting operations such as soldering on its surface. Therefore, it needs to be solved. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art: most of the existing fixtures for PCB board processing are fixedly installed, and can only position a single PCB board, and cannot adapt to the placement of multi-specification PCB boards, so there are certain limitations. At the same time, after some fixtures for PCB board processing position the PCB board, it is easy for some parts to block the PCB board, thus affecting operations such as soldering on its surface.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a fixture for PCB board processing, including: a support base, and a plurality of anti-slip feet provided at the four corners of one side surface of the support base; further including:

[0006] Two slots are opened symmetrically on the surface of the support base, and a first threaded rod is arranged inside the two slots;

[0007] Two moving blocks are threadedly sleeved on the outer surfaces of the two first threaded rods, and a guide rod is movably embedded inside the two moving blocks.

[0008] Preferably, the two guide rods are fixedly arranged on the inner walls of the two slots, and long slots are opened on the surfaces of the two moving blocks away from the anti-slip feet.

[0009] The technical effect of adopting the above further solution is that the guide rod inside the notch limits the movement block, and at the same time, a long groove is provided on the surface of the movement block to facilitate the installation and positioning of internal parts.

[0010] Preferably, a second threaded rod is arranged inside the two long grooves, and sliders are sleeved on the outer surfaces of the two second threaded rods in a threaded manner.

[0011] The technical effect of adopting the above further solution is that when the second threaded rod inside the long groove is rotated, the slider on the outer surface is driven to adjust its position.

[0012] Preferably, the two sliders are slidably embedded inside the long grooves, and mounting plates are installed on the surfaces of the two sliders through bolts.

[0013] The technical effect of adopting the above further solution is that the long grooves limit the sliders, and at the same time, the mounting plates on the surfaces of the sliders can be replaced.

[0014] Preferably, positioning posts are arranged on one side surface of the two mounting plates, and a load-bearing plate is arranged on the surface of the support base away from the center of the anti-slip feet.

[0015] The technical effect of adopting the above further solution is that the positioning posts on the surface of the mounting plate are embedded inside the round holes on the surface of the PCB board for positioning, and at the same time, the load-bearing plate on the surface of the support base facilitates the placement of the PCB board.

[0016] Preferably, a limiting groove is opened on one side surface of the load-bearing plate, and a bidirectional lead screw is arranged inside the limiting groove.

[0017] The technical effect of adopting the above further solution is that the bidirectional lead screw is positioned through the limiting groove opened on the surface of the load-bearing plate.

[0018] Preferably, limit blocks are sleeved on the surfaces of the symmetric parts of the bidirectional lead screw in a threaded manner, and the two limit blocks are slidably embedded inside the limiting groove.

[0019] The technical effect of adopting the above further solution is that when the bidirectional lead screw is rotated, the limit blocks on the surface perform a centering movement inside the limiting groove, thereby positioning PCB boards of different sizes.

[0020] Preferably, positioning plates are arranged on one side surfaces of the two limit blocks, and protective pads are arranged on one side surfaces of the two positioning plates.

[0021] The technical effect of adopting the above further solution is that when the limit blocks move, the positioning plates on the surfaces are driven to move, and together with the protective pads, a protective effect is provided for the PCB board.

[0022] Compared with the prior art, the advantages and positive effects of the present utility model are as follows

[0023] 1. In the present utility model, according to PCB boards of different specifications, the first threaded rod is adjusted to drive the moving block to move horizontally along the guide rod, and then the second threaded rod is rotated to drive the slider provided with the threaded sleeve on the surface to move longitudinally inside the long groove.

At the same time, it can be adjusted according to PCB boards of different sizes, improving the applicability of the device.

In the present utility model, after initially positioning the PCB board on the surface of the load-bearing plate, by rotating the bidirectional lead screw, the limiting block is driven to perform a centering movement inside the limiting groove, and at the same time, a limiting function is provided. The positioning plate is driven to assist in positioning both sides of the PCB board. The protective pads on the surface provide a protective function for the PCB board, completing the overall positioning work of the PCB board. At the same time, the surface of the PCB board is not blocked, facilitating processing at any position on its surface, and the operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS
