[0001] This application relates to the technical field of PCB board quality inspection devices, and in particular to a PCB control board quality inspection device. Background Technology

[0002] In the rapid development of the electronics manufacturing industry, PCB (printed circuit board) is a basic component of electronic devices, and its quality control has become an indispensable part of the production process. The flatness of the PCB board is one of the key indicators for measuring its manufacturing quality. It is directly related to the performance stability, signal transmission efficiency and overall reliability of electronic products. Uneven PCB boards may lead to problems such as poor installation of electronic components, soldering defects and short circuits, which in turn affect the function and lifespan of the product.

[0003] Traditional methods for inspecting the flatness of PCB boards typically rely on manual operation using measuring tools such as vernier calipers. This method is not only inefficient but also susceptible to human error, leading to inaccurate measurement results.

[0004] Therefore, those skilled in the art have provided a PCB control board quality inspection device to solve the problems mentioned in the background art. Utility Model Content

The fixing assembly includes a first mounting plate. A mounting block is fixedly connected to the upper center of the first mounting plate. A threaded rod is threadedly connected to both ends of the mounting block. A clamping bar is rotatably connected to the rear end of the threaded rod. Another clamping bar is fixedly connected to the upper rear end of the first mounting plate. The two clamping bars are symmetrically arranged. A plurality of first mounting cavities are centrally formed on the inner side of the clamping bar. A square block is slidably connected to the inner side of the first mounting cavity. A spring is installed between the square block and the first mounting cavity. A connecting rod is fixedly connected to the side wall of the square block.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] like Figure 1-3 As shown, this application discloses a PCB control board quality inspection device, including a fixing component 1. A detection component 2 is fixedly connected to the rear end of the fixing component 1. The fixing component 1 includes a first mounting plate 101. A mounting block 102 is mounted on the upper end of the first mounting plate 101, positioned towards the front. A threaded rod 103 is mounted through both ends of the mounting block 102. A clamping strip 105 is mounted on the rear end of the threaded rod 103. Another clamping strip 105 is mounted on the upper end of the first mounting plate 101, towards the rear. The two clamping strips 105... 05 Symmetrical arrangement, a plurality of first mounting cavities 106 are centrally opened on the inner side of the clamping bar 105, a square block 108 is installed on the inner side of the first mounting cavity 106, a spring 112 is installed between the square block 108 and the first mounting cavity 106, a connecting rod 109 is installed on the side wall of the square block 108, a clamping plate 110 is installed at the end of the connecting rod 109, a plurality of protrusions 111 are provided on the side wall of the clamping plate 110, and a second mounting cavity 107 is opened between the clamping bar 105 and the clamping plate 110;

[0021] The PCB board is placed on the first mounting plate 101. Rotating the threaded rod 103, in conjunction with the mounting block 102, moves the front clamping bar 105 closer to the rear clamping bar 105. The two clamping bars 105 clamp and fix the PCB board. During clamping, the spring 112 pushes the square block 108, connecting rod 109, and clamping plate 110 to contact the edge of the PCB board. The protrusions 111 on the clamping plate 110 increase the friction against the edge of the PCB board. This prevents the dial indicator 205 from contacting the PCB board during measurement, which could cause deformation and affect the accuracy of the measurement.

[0022] like Figure 1 As shown, the detection component 2 includes a second mounting plate 201. The front end of the second mounting plate 201 is fixedly connected to the first mounting plate 101. A crossbar 202 is fixedly connected to the upper end of the second mounting plate 201. A sliding sleeve 203 is installed on the outer side of the crossbar 202. A mounting bracket 204 is installed on the sliding sleeve 203. A dial indicator 205 is installed at the end of the mounting bracket 204. The mounting bracket 204 can adjust the position of the dial indicator 205. By moving the sliding sleeve 203 along the direction of the crossbar 202, the dial indicator 205, which is in contact with the upper surface of the PCB board, can be moved. The flatness of the PCB board can be measured by referring to the reading of the dial indicator 205.

[0023] like Figure 1-2As shown, T-shaped movable blocks 113 are installed at the bottom and on both sides of the clamping bar 105. Two T-shaped mounting slots 114 are provided on the first mounting plate 101. The movable blocks 113 are installed in the mounting slots 114. By setting the movable blocks 113 to work with the mounting slots 114, the clamping bar 105 can be limited.

[0024] like Figure 1-2 As shown, handles 104 are installed on both sides of the threaded rod 103 near the front end. By installing handles 104 on the threaded rod 103, the threaded rod 103 can be rotated by the handles 104.

[0025] like Figure 1 As shown, vertical surfaces are provided on the front and rear side walls of the crossbar 202. Several balls are installed on the inner side of the sliding sleeve 203. The balls are in contact with the crossbar 202. By providing vertical surfaces on the crossbar 202, the sliding sleeve 203 can be limited. The balls inside the sliding sleeve 203 can improve the smoothness of the movement of the sliding sleeve 203.

[0026] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] The implementation principle of a PCB control board quality inspection device according to an embodiment of this application is as follows:

[0029] In use, the PCB board is placed between the two clamping bars 105 on the first mounting plate 101. Holding the handle 104, the threaded rod 103 is rotated clockwise. The threaded rod 103 is threadedly connected to the mounting block 102. The displacement of the threaded rod 103 causes the clamping bar 105 to move closer to the other clamping bar 105. The moving block 113 at the bottom of the clamping bar 105 moves within the mounting groove 114, ensuring the stability of the clamping bar 105's movement and clamping the PCB board. When clamping the PCB board, the PCB board contacts the clamping plate 110, squeezing the clamping plate 110 into the second mounting cavity 107. The square block 108, in conjunction with the connecting rod 109 and the spring 112, ensures tight contact between the clamping plate 110 and the PCB board, while preventing damage. Excessive pressure on the PCB board causes deformation. The protrusions 111 on the clamping plate 110 contact the side wall of the PCB board to increase the friction on the edge of the PCB board, ensuring that the PCB board will not shift between the two clamping bars 105 during measurement. Before measurement, the position of the dial indicator 205 is adjusted by the mounting bracket 204, and the dial indicator 205 is calibrated using a test block. During measurement, the sliding sleeve 203 is pushed to move along the direction of the crossbar 202, and the dial indicator 205 contacts the upper end of the PCB board. The position of the pointer on the dial indicator 205 is used to determine whether the curvature is qualified. After the test is completed, the sliding sleeve 203 is pushed to the end of the crossbar 202, and the sliding sleeve 203 is rotated in the opposite direction to release the PCB board. This operation is repeated.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.

The scope of protection of this utility model is defined by the appended claims and their equivalents.
