Description

Technical Field

[0001] This utility model relates to the field of testing technology, and more specifically, to a PCB panel testing device. Background Technology

[0002] PCB panelization involves combining multiple individual boards (boards without interconnections) into a single board for simultaneous production. This allows for the production of multiple boards at once, resulting in high speed. After panelization, the PCBs need to be inspected to prevent defective boards from entering the market. During testing, workers typically manually place the PCBs onto the testing platform of a testing device, where a pressure plate above the platform presses the boards down. Because the pressure plate is located directly above the testing platform, workers are prone to accidentally pressing down on their hands when placing the PCBs.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PCB panel inspection device that solves the problem of accidentally pressing on the hand during the inspection of existing PCB panels.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The embodiments of this application provide a PCB panel inspection device, including a frame, a worktable on the frame, an inspection groove on the worktable, a probe in the inspection groove, pins around the inspection groove, a pressing component above the inspection groove, the pressing component being slidably connected to the worktable, and a first driving component on the frame capable of driving the pressing component to move along the Y-axis. The pressing component includes a pressure plate and a second driving component driving the pressure plate to move up and down along the Z-axis.

[0006] In one embodiment, slide rails are provided on the worktables on both sides of the detection groove, and the pressing component includes two sliders, which are slidably connected to the two slide rails respectively.

[0007] In one embodiment, the first drive assembly includes a first electric cylinder, a first fixing plate is disposed on the frame, one end of the first electric cylinder is fixedly connected to the fixing plate, a second fixing plate is disposed on one of the sliders, and the other end of the first electric cylinder is fixedly connected to the second fixing plate.

[0008] In one embodiment, the second drive assembly includes a second electric cylinder, a connecting rod fixedly connected to the slider, the connecting rod extending upward along the Z-axis, a third fixing plate fixedly connected to the upper part of the connecting rod, a fixing tube fixedly connected to the upper part of the third fixing plate, a moving rod slidably connected inside the fixing tube, the lower part of the moving rod fixedly connected to the pressure plate, the second electric cylinder fixedly connected to the third fixing plate, and the output end of the second electric cylinder fixedly connected to the pressure plate.

[0009] In one embodiment, each probe has a plurality of conical blocks at its top, the plurality of conical blocks being arranged in an array at intervals along the outer periphery of the probe, and the plurality of conical blocks together forming a groove.

[0010] In summary, this utility model has the following beneficial effects: By setting a detection groove on the workbench and setting pins around the detection groove, the pins can position the PCB panel around its perimeter, ensuring that the detection points on the PCB panel correspond to the probes. A pressing component that can move along the Y-axis is also provided, allowing the pressing component to be moved away from directly above the panel during PCB panel placement, preventing accidental pressure and injury to workers. After the PCB panel is placed, the pressing component is moved to directly above the PCB panel, and then the pressure plate is driven to press down on the PCB panel. By placing the probe 1111 below the PCB panel, pressing down on the PCB panel ensures contact between the PCB panel and the probe. The pressure plate and the PCB panel have the same shape, guaranteeing good contact between the PCB panel and the probe 1111. This avoids the problem of poor contact when the PCB panel is uneven when the probe is placed above it. Multiple conical blocks are set on the probe, providing multiple contact points between the probe and the PCB panel, ensuring good contact. Attached Figure Description

[0017] 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.

[0018] like Figures 1 to 5 As shown, an embodiment of this application provides a PCB panel inspection device, including a frame 1, a worktable 11 on the frame 1, an inspection groove 111 on the worktable 11, a probe 1111 inside the inspection groove 111, pins 112 around the inspection groove 111, a pressing component 2 above the inspection groove 111, the pressing component 2 being slidably connected to the worktable 11, and a first driving component on the frame 1 capable of driving the pressing component 2 to move along the Y-axis, the pressing component 2 including a pressure plate 21 and a second driving component driving the pressure plate 21 to move up and down along the Z-axis.

[0019] Specifically, the PCB panel has four positioning holes, and the shape of the pressure plate 21 is the same as that of the PCB panel.

[0020] During operation, the worker aligns the positioning holes on the PCB panel with the pins 112. The pins 112 around the detection slot 111 position the PCB panel so that it is above the detection slot 111. Then, the first drive component drives the pressing component 2 to move above the PCB panel, and the second drive component drives the pressure plate 21 to descend and press down the PCB panel so that the detection points on the PCB panel come into contact with the probes 1111 to detect the PCB panel.

[0021] The above structure is configured by setting a detection groove 111 on the workbench 11 and setting pins 112 around the detection groove 111, so that the pins 112 can position the PCB panel around the perimeter, so that the detection points on the PCB panel correspond to the probes 1111. A pressing component 2 that can move along the Y-axis is set so that when placing the PCB panel, the pressing component 2 can be moved away from the top of the PCB panel to prevent the pressure plate 21 from accidentally pressing down and causing injury to the staff. After the PCB panel is placed, the pressing component 2 is moved to the top of the PCB panel, and then the pressure plate 21 is driven to press down the PCB panel. By setting the probes 1111 below the PCB panel, pressing down the PCB panel will make the PCB panel contact the probes 1111. The pressure plate and the PCB panel have the same shape, which can ensure good contact between the PCB panel and the probes 1111 and avoid the problem of poor contact when the PCB panel is not placed evenly when the probes 1111 are set above the PCB panel.

[0022] In this embodiment, slide rails 113 are provided on the worktables 11 on both sides of the detection groove 111, and the pressing component 2 includes two sliders 22, which are slidably connected to the two slide rails 113 respectively.

[0023] In this embodiment, the first driving component includes a first electric cylinder 3, a first fixing plate 12 is provided on the frame 1, one end of the first electric cylinder 3 is fixedly connected to the fixing plate, a second fixing plate 221 is provided on one of the sliders 22, and the other end of the first electric cylinder 3 is fixedly connected to the second fixing plate 221.

[0024] Specifically, the output end of the first electric cylinder 3 can extend and retract along the Y-axis. The output end of the first electric cylinder 3 is fixedly connected to the second fixed plate 221. When the output end of the first electric cylinder 3 moves, it drives the second fixed plate 221 to move along the Y-axis. The second fixed plate 221 is fixedly connected to one of the sliders 22, so that the slider 22 moves along the slide rail 113, and the pressing component 2 moves along the Y-axis.

[0025] In this embodiment, the second driving component includes a second electric cylinder 2234. A connecting rod 222 is fixedly connected to the slider 22. The connecting rod 222 extends upward along the Z-axis. A third fixing plate 223 is fixedly connected to the upper part of the connecting rod 222. A fixing tube 2233 is fixedly connected to the upper part of the third fixing plate 223. A moving rod 2232 is slidably connected inside the fixing tube 2233. The lower part of the moving rod 2232 is fixedly connected to the pressure plate 21. The second electric cylinder 2234 is fixedly connected to the third fixing plate 223. The output end of the second electric cylinder 2234 is fixedly connected to the pressure plate 21.

[0026] When working, when the output end of the second electric cylinder 2234 extends and retracts, it moves the pressure plate 21 up and down. When the pressure plate 21 moves downward, it can press the PCB panel tightly.

[0027] In this embodiment, each probe 1111 has a plurality of conical blocks 11111 on its top. The plurality of conical blocks 11111 are arranged in an array at intervals along the outer periphery of the probe 1111, and the plurality of conical blocks 11111 together form a groove.

[0028] Specifically, the plurality of conical blocks 11111 form a shape similar to a permanent tooth.

[0029] The above structure, by setting multiple conical blocks 11111 on the probe 1111, makes the probe 1111 have multiple contact points with the PCB panel, thus making the contact between the probe 1111 and the PCB panel better.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
