Technical Field

[0001] This utility model relates to the field of PCBA boards, and in particular to a PCBA board appearance inspection device. Background Technology

[0002] PCBA boards refer to printed circuit boards that have already completed component assembly (soldering). The main function of using optical inspection instruments is to use imaging, scanning and identification components to identify appearance defects and problems of PCBA boards, thereby ensuring product quality and production efficiency.

[0003] Existing technologies, such as the utility model patent with publication number CN216792064U, disclose a high-efficiency PCBA board appearance inspection device. This patent adopts an appearance inspection structure, which includes a first conveyor belt, a second conveyor belt, a machine body, an infrared scanning device, a first push plate, and a first cylinder. The first and second conveyor belts are each equipped with a machine body, and the infrared scanning device is installed inside the machine body. A first push plate is installed on one side of the machine body, and a first cylinder is installed on the outside of the machine body. One end of the first cylinder is embedded in the machine body and connected to the first push plate. This device replaces manual inspection with machine inspection, and the inspection is more detailed and efficient than manual inspection.

[0004] The inventors discovered the following problems in their daily work when using the optical inspection instrument: when inspecting multiple plates, it is inconvenient and time-consuming for the user to change the plates to be inspected, resulting in low efficiency of plate appearance inspection. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the cumbersome and inefficient process of directly replacing the test board.

[0006] To solve the above-mentioned technical problems, this utility model provides a PCBA board appearance inspection device, including: a body, two boards, an adjustment structure, and an auxiliary structure. An imager is installed on the upper surface of the body, and a worktable is installed on the upper surface of the body. An adjustment structure is provided on the upper surface of the body corresponding to the worktable. The adjustment structure includes two support frames, which are fixedly connected to the body by means of the auxiliary structure. A bidirectional screw is rotatably connected to the inner wall of one support frame, and a round rod is fixedly connected to the inner wall of the other support frame. Two moving frames are threadedly connected to the arc surface of the bidirectional screw, and the two moving frames are slidably connected to the arc surface of the round rod. Mounting frames are slidably connected to the inner walls of both moving frames. The side of the two mounting frames that is close to each other abuts against the board. Two sliding rods are fixedly connected to the side of the two mounting frames that is far from each other. The arc surface of the sliding rods is slidably connected to the moving frames. A positioning plate is fixedly connected to one side of one mounting frame, and a positioning rod is fixedly connected to the other mounting frame at the position corresponding to the positioning plate. The arc surface of the positioning rod is slidably connected to the positioning plate.

[0007] The effect achieved by the above components is that the plate can be alternately inspected using the two slots on the mounting frame, and the distance between the two mounting frames can be easily adjusted to improve inspection efficiency.

[0008] Preferably, a scale is provided on the inner wall of the support frame at the position corresponding to the bidirectional screw.

[0009] The effect achieved by the above components is: by referring to the scale, users can easily and intuitively judge the distance between the two moving frames and the mounting frame.

[0010] Preferably, anti-slip strips are fixedly connected to the sides of the two mounting frames that are close to each other, and the anti-slip strips are rubber strips.

[0011] The effect achieved by the above components is to increase the friction of the inner wall of the mounting frame by using anti-slip strips, making the plate more stable when it is located between two mounting frames.

[0012] Preferably, a limiting rod is fixedly connected to the surface of one of the mounting frames, and a limiting disc is threadedly connected to the arc surface of the limiting rod.

[0013] The effect achieved by the above components is as follows: when the limiting plate is rotated, the limiting plate approaches and presses against the moving frame along the limiting rod by means of the thread, thus temporarily limiting the position of the mounting frame.

[0014] Preferably, both ends of the bidirectional screw are fixedly connected with a plurality of anti-slip protrusions, and the plurality of anti-slip protrusions are evenly distributed on the bidirectional screw.

[0015] The effect achieved by the above components is to increase the friction at both ends of the bidirectional screw through the anti-slip protrusions, making it easier for the user to rotate the bidirectional screw.

[0016] Preferably, auxiliary structures are provided on both sides of the machine body at positions corresponding to the support frame. The auxiliary structures include two auxiliary slots, which are formed on the machine body. An auxiliary block is slidably connected to the inner wall of the auxiliary slot. The upper surface of the auxiliary block is fixedly connected to the support frame. An auxiliary rod is slidably connected to both sides of the machine body at positions corresponding to the auxiliary slots. A spring is fixedly connected to the end of the auxiliary rod away from the auxiliary slot. The end of the spring away from the auxiliary rod is fixedly connected to the machine body. An auxiliary hole is formed on the surface of the auxiliary block. The inner wall of the auxiliary hole is slidably connected to the auxiliary rod.

[0017] The above-mentioned components achieve the following effects: the operating auxiliary rod releases the limit on the auxiliary block, allowing for convenient installation and removal of the support frame, facilitating subsequent maintenance, and providing high flexibility.

[0018] Preferably, a lever plate is fixedly connected to the surface of the auxiliary rod, and the lever plate is a rectangular plate.

[0019] The effect achieved by the above components is that the operating lever moves the auxiliary rod, making it easier for the user to move the lever.

[0020] Compared with related technologies, the PCBA board appearance inspection device provided by this utility model has the following beneficial effects:

[0021] By setting an adjustment structure, the positions of the two mounting frames can be adjusted along the moving frame. Several boards can be alternately inspected using the two slots on the mounting frames. When inspecting a board, the board to be inspected can be disassembled and assembled, improving the efficiency of board inspection. The distance between the two mounting frames can be easily adjusted according to the width of the boards in the same batch, making it highly practical.

[0022] By setting up an auxiliary structure and operating the auxiliary rod to release the limit on the auxiliary block, the support frame can be easily installed and removed, facilitating subsequent maintenance and offering high flexibility. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 4 The present invention provides a PCBA board appearance inspection device, comprising: a body 1, two boards 4, an adjustment structure 5 and an auxiliary structure 6. An imager 2 is installed on the upper surface of the body 1, a worktable 3 is installed on the upper surface of the body 1, an adjustment structure 5 is provided on the upper surface of the body 1 corresponding to the position of the worktable 3, and auxiliary structures 6 are provided on both sides of the body 1 corresponding to the positions of the support frame 501.

[0032] In the embodiments of this utility model, please refer to Figure 1 and Figure 4The adjustment structure 5 includes two support frames 501, which are fixedly connected to the body 1 via an auxiliary structure 6. A bidirectional screw 502 is rotatably connected to the inner wall of one support frame 501. Round rods 504 are fixedly connected to the inner walls of both support frames 501. Two movable frames 503 are threadedly connected to the arc surface of the bidirectional screw 502. The two movable frames 503 are slidably connected to the arc surface of the round rods 504. Mounting frames 506 are slidably connected to the inner walls of both movable frames 503. The two mounting frames 506 are close to each other. The two mounting frames 506 abut against the plate 4. Two sliding rods 507 are fixedly connected to the opposite sides of each mounting frame 506. The arc surface of the sliding rod 507 is slidably connected to the moving frame 503. A positioning plate 509 is fixedly connected to one side of one mounting frame 506, and a positioning rod 510 is fixedly connected to the other mounting frame 506 at the position corresponding to the positioning plate 509. The arc surface of the positioning rod 510 is slidably connected to the positioning plate 509. The plate 4 is alternately inspected using two slots on the mounting frame 506. The distance between the two mounting frames 506 can be... To facilitate easy adjustments and improve testing efficiency, a scale 505 is provided on the inner wall of the support frame 501 at the position corresponding to the bidirectional screw 502. Referring to the scale 505, users can easily and intuitively judge the distance between the two moving frames 503 and the mounting frame 506. Anti-slip strips 508 are fixedly connected to the sides of the two mounting frames 506 that are close to each other. The anti-slip strips 508 are rubber strips that increase the friction on the inner wall of the mounting frame 506, making the plate 4 more stable when positioned between the two mounting frames 506. One of the mounting frames 503... The surface of the 06 is fixedly connected to a limiting rod 511. The arc surface of the limiting rod 511 is threadedly connected to a limiting disc 512. When the limiting disc 512 is rotated, the limiting disc 512 moves closer to and presses against the moving frame 503 along the limiting rod 511 by means of the thread, thus temporarily limiting the position of the mounting frame 506. Both ends of the bidirectional screw 502 are fixedly connected to several anti-slip protrusions. The several anti-slip protrusions are evenly distributed on the bidirectional screw 502. The anti-slip protrusions increase the friction at both ends of the bidirectional screw 502, making it easier for the user to rotate the bidirectional screw 502.

[0033] In the embodiments of this utility model, please refer to Figure 1 and Figure 4The auxiliary structure 6 includes two auxiliary slots 61, which are formed on the body 1. An auxiliary block 62 is slidably connected to the inner wall of the auxiliary slot 61. The upper surface of the auxiliary block 62 is fixedly connected to the support frame 501. An auxiliary rod 63 is slidably connected to both sides of the body 1 at the positions corresponding to the auxiliary slots 61. A spring 64 is fixedly connected to the end of the auxiliary rod 63 away from the auxiliary slot 61. The end of the spring 64 away from the auxiliary rod 63 is fixedly connected to the body 1. An auxiliary hole 65 is formed on the surface of the auxiliary block 62. The inner wall of the auxiliary hole 65 is slidably connected to the auxiliary rod 63. By operating the auxiliary rod 63, the limitation on the auxiliary block 62 can be released, and the support frame 501 can be easily installed and removed, which is convenient for subsequent maintenance and has high flexibility. A lever 66 is fixedly connected to the surface of the auxiliary rod 63. The lever 66 is a rectangular plate. By operating the lever 66, the auxiliary rod 63 can be moved, which is convenient for the user to move the lever 66.

[0034] The working principle of the PCBA board appearance inspection device provided by this utility model is as follows: By setting the adjustment structure 5, the bidirectional screw 502 is first rotated. The bidirectional screw 502 rotates along the inner wall of the support frame 501. The bidirectional screw 502 drives the two moving frames 503 to move synchronously in a direction away from or towards each other through the thread. The moving frames 503 slide along the round rod 504. During this process, the moving frames 503 drive the mounting frames 506 to move, so that the two mounting frames 506 move in a direction closer to or further away from each other. According to the width of the board body 4 to be inspected, the distance between the two mounting frames 506 is adjusted. During the movement of the two mounting frames 506, the positioning rod 510 always slides along the positioning plate 509. Then, the board body 4 is placed between the two mounting frames 506, and the board body 4 is kept close to the bidirectional screw 502. Then, the mounting frames 506 are pushed towards the position directly below the imager 2. The mounting frames 506 cooperate with the sliding rod. 507 slides along the inner wall of the moving frame 503. One of the mounting frames 506 uses the positioning plate 509 and the positioning rod 510 to drive the other mounting frame 506 to move. When the plate 4 is directly below the imager 2 for detection, the user can put the other plate 4 to be tested into the mounting frame 506 from the position near the round rod 504. The plates to be tested are placed alternately. The scale 505 is used to help the user intuitively judge the distance between the two moving frames 503 and the mounting frame 506. The anti-slip strip 508 increases the friction of the inner wall of the mounting frame 506, making the plate 4 more stable when it is between the two mounting frames 506. The limiting plate 512 is rotated. The limiting plate 512 approaches and presses the moving frame 503 along the limiting rod 511 with the help of the thread, temporarily limiting the position of the mounting frame 506. The anti-slip protrusion increases the friction at both ends of the bidirectional screw 502, making it easier for the user to rotate the bidirectional screw 502.

[0035] By setting the auxiliary structure 6, the auxiliary rod 63 is first moved away from the auxiliary groove 61. During this process, the auxiliary rod 63 slides away from the auxiliary hole 65 on the auxiliary block 62, releasing the limit on the auxiliary block 62. The spring 64 is in a compressed state. Similarly, the auxiliary rod 63 on the other side of the machine body 1 is adjusted. Then the support frame 501 can be moved upward. The support frame 501 drives the auxiliary block 62 to slide upward away from the auxiliary groove 61. The operating dial 66 drives the auxiliary rod 63 to move, making it convenient for the user to move the dial 66.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
