Description

Technical Field

[0001] The utility model belongs to the technical field related to remote control PCB board processing, in particular to a clamping device for remote control PCB board detection. Background Art

[0002] During the production of remote control PCB boards, after various electronic components are soldered on the surface, the PCB needs to be statically inspected to learn about the operation of the remote control PCB board circuit and the performance of the board. The static method refers to not running the program being tested itself, but only checking the correctness of the program by analyzing or checking the syntax, structure, process, interface, etc. of the source program. The static test results can be used for further error checking and provide guidance for the selection of test cases. During static testing, a clamping device is needed to fix the PCB. Existing clamping devices, such as the clamping device of a PCB board static tester disclosed in patent application number 201821050876.7, clamp the PCB board with two load-bearing clamping arms, which makes the middle and both ends easily warped, affecting the fixing effect. In addition, the output interface 21 (such as the output interface 21 provided at the bottom of the PCB board) needs to be fixed to the structure in the later stage. Figure 1 As shown in FIG, each detection port is manually connected in sequence through a detection connection line. After the detection is completed, each detection connection line needs to be removed, which ultimately affects the detection efficiency. Therefore, improvement is needed. Utility Model Content

Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 2-6 As shown, the present embodiment discloses a clamping device for detecting a remote control PCB board, comprising a detection box 1 and a push-pull quick clamp 2, wherein the detection box 1 is provided with a work surface 101, and the work surface 101 is provided with a supporting platform 3 and a back plate 4, the upper surface of the supporting platform 3 is provided with two rows of boss groups distributed front and back, and each row of boss groups includes one or more positioning bosses 5 arranged at intervals, a fixing bracket 23 is fixed on the back plate 4, a push-pull quick clamp 2 is fixed above the fixing bracket 23, a pressing plate 6 is fixed below the push rod on the push-pull quick clamp 2, and two rows of positioning pin groups distributed front and back are provided below the pressing plate 6, and each row of positioning pin groups includes one or more positioning pins arranged at intervals. Pin 7, the work surface 101 is also provided with a detection pin assembly located on the side of the supporting platform 3 and close to the output interface 21 of the remote control PCB board, the detection pin assembly includes a push-pull quick clamp 28, a sliding plate 9 and a detection pin seat 10, the push-pull quick clamp 28 is fixed on the mounting seat 17, the mounting seat 17 is set on the work surface 101, the push rod of the push-pull quick clamp 28 is connected to the sliding plate 9, and the other end of the sliding plate 9 is connected to the detection pin seat 10, and the detection pin seat 10 is provided with one or more detection probes 11, and the detection probes 11 can be electrically connected to the output interface 21 of the remote control PCB board after the sliding plate 9 moves.

[0030] Preferably, in order to facilitate fixation, a slider three 12 is provided at the bottom of the sliding plate 9, and the slider three 12 is slidably connected to a slide seat 13, and the slide seat 13 is provided on the work table 101. The above structure can achieve a guiding role when the sliding plate 9 moves.

[0031] Preferably, in order to realize the guiding effect when moving up and down, two guide rods 24 are fixed on the left and right sides of the fixed bracket 23, and the lower part of the guide rods 24 is fixed on the work table 101. A flange bearing 25 is provided on the left and right sides of the pressure plate 6, and each guide rod 24 is movably inserted into a corresponding flange bearing 25. By adding the guide rods 24, the pressure plate 6 can play a guiding role when moving up and down.

[0032] Preferably, in order to clean the upper surface of the remote control PCB board, one or more blowing joints 26 are provided at the rear of the supporting platform 3, and one or more blowing holes 27 are provided on the upper surface of the supporting platform 3. One end of the blowing joint 26 is connected to a corresponding blowing hole 27. Through the above-mentioned structural setting, the various blowing joints 26 are connected together in the later stage, and then connected to an air supply device. The air supply device is used to blow air into the blowing holes 27, so as to achieve high-pressure blowing on the side of the remote control PCB board containing the buttons, thereby cleaning the upper surface of the remote control PCB board.

[0033] The working principle of this structure is as follows: First, the ends of each detection probe 11 away from the detection probe 11 are connected to the detection interface of the existing static detection equipment through connecting wires. Once connected, they can be wirelessly disassembled later. Only when no detection is performed, the connecting wires are removed. Compared with the existing detection method, it is not necessary to remove the wires and connect them every time a remote control PCB board is detected. The operation is convenient and simple, and the efficiency is improved. At the same time, it will not affect the detection efficiency. Then, the remote control PCB board that needs to be statically detected (such as Figure 1 When placing it, place the side with the button downward and the side with the output interface 21 upward, and align it with the detection pin assembly. Manually bend the push-pull quick clamp 2, and the push rod of the push-pull quick clamp 2 moves downward to drive the pressure plate 6 to move downward until the positioning pressure pin 7 is pressed against the remote control PCB board, so that the remote control PCB board is clamped under the action of the positioning pressure pin 7 and the positioning boss 5. Then bend the push-pull quick clamp 2 8 to drive the sliding plate 9 to move back and forth until the detection probe 11 can be inserted into the output interface 21 of the remote control PCB board to achieve quick connection. Therefore, through this structural setting, since the remote control PCB board is clamped using multiple positioning pressure pins 7 in conjunction with multiple positioning bosses 5 for cooperation and compression, it is guaranteed that the pressing is more uniform and more stable, and there will be no problem of warping at both ends.

An adjusting screw 19 is threadedly connected to the side of the detection box 1. The rod of the adjusting screw 19 is inserted into the slide rail 14 and rotatably connected to the slider 18. The above-mentioned structural arrangement can horizontally adjust the position of the detection pin seat 10, so that it can detect remote control PCB boards of different lengths, thereby improving applicability. During operation, the position of the detection pin seat 10 is adjusted by rotating the adjusting screw 19 and then driving the slider 18 to move horizontally along the slide rail 2 15.
