Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, and in particular to a positioning device for the production of PCB boards for law enforcement recorders. Background Technology

[0002] Positioning devices for law enforcement recorder PCB board production are designed to precisely position and fix PCB boards during the printed circuit board manufacturing process. Such devices are crucial for ensuring the accuracy and consistency of PCB boards in each production step.

[0003] Chinese Patent Publication No. CN211378395U, published on August 28, 2020, discloses a positioning device for the production of PCB boards for dashcams. The device includes a workbench, on which a fixing plate and a fixing frame are fixedly connected from front to back on the upper surface of the workbench. An electric push rod is fixedly connected to the back of the fixing plate, and an adjusting block is fixedly connected to the end of the electric push rod away from the fixing plate. A sliding groove is formed on the upper surface of the adjusting block, and a slider is slidably connected inside the sliding groove. A positioning frame is fixedly connected to the upper surface of the slider, and a PCB board is disposed inside the positioning frame.

[0004] Existing positioning devices for PCB board production, such as those mentioned above, mostly use a drive component to move two sets of clamping plates relative to each other to position the PCB board. However, in practice, it is not easy to accurately control the relative movement distance between the two sets of clamping plates. In addition, the PCB board of the law enforcement recorder is relatively thin, and the clamping method of the two sets of clamping plates can easily cause deformation or even breakage of the PCB board. Therefore, there is an urgent need to propose a corresponding positioning device for the production of law enforcement recorder PCB boards to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning device for the production of PCB boards for law enforcement recorders in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning device for producing a law enforcement recorder PCB board includes two sets of base frames. The top of each set of base frames is integrated with a top frame and a lifting component for fixing the top frame. Each set of top frames is fixedly connected to two sets of top seats. The four sets of top seats are arranged in a rectangular shape. Each set of top seats has a slot and a pressing component integrated on its top.

[0008] Preferably, a vertical bar is fixedly connected to the bottom of the top frame, the vertical bar is inserted into the vertical end of the base frame, and a locking rod is screwed onto the outer wall of the base frame, with the open end of the locking rod abutting against the outer wall of the vertical bar.

[0009] Preferably, a connecting strip is fixedly connected between the two groups of horizontal ends of the chassis, and a strip-shaped slot is formed in the connecting strip.

[0010] Preferably, the pressing assembly comprises a screw rod screw-coupled with an inner wall of a top portion of the top seat, and a pressing block fixedly connected to a top portion of the screw rod.

[0011] Preferably, a rubber pad is fixedly connected to a bottom portion of the pressing block.

[0012] Preferably, a limiting rod is fixedly connected to a top portion of the top seat.

[0013] As described above, the present application has the following advantages:

[0014] 1. In the present application, four groups of top seats are distributed in a rectangular shape, and the gaps at four corners of the PCB board of the law enforcement recorder are matched with the four groups of top seats. After the PCB board of the law enforcement recorder is combined with the four groups of clamping grooves on the four groups of top seats, the four groups of pressing blocks are actuated. During the actuation of the pressing blocks, the screw rods at the bottom portions of the pressing blocks are screw-coupled with the inner walls of the top seats. At the same time, the pressing blocks are axially deflected, and move downward along with the screw rods. When the pressing blocks are placed on the top portion of the PCB board of the law enforcement recorder, the rubber pads at the bottom portions of the pressing blocks abut against the top portion of the PCB board of the law enforcement recorder. In this way, the positioning of the PCB board of the law enforcement recorder is realized. The four groups of top seats which are arranged in a profiled manner are matched with the clamping grooves and the corresponding pressing assemblies, so that the stability and convenience of the positioning of the PCB board of the law enforcement recorder are ensured.

[0015] 2. In the present application, the top frame is lifted to drive the top seats, and the vertical bars at the bottom portion of the top frame are synchronously and slidingly matched with the inner walls of the vertical ends of the chassis. After the top seats are adjusted to appropriate vertical positions, the locking rods are rotated to be screw-coupled with the outer walls of the vertical ends of the chassis. The open ends of the locking rods are in contact with the outer walls of the vertical bars to realize the repositioning of the top frame, so that the positioning height of the PCB board of the law enforcement recorder can be conveniently adjusted according to the use requirements.
