Description

Technical Field

[0001] This utility model relates to the field of circuit board testing technology, and in particular to a testing device for identifying circuit board patterns. Background Technology

[0002] Circuit boards, as a core component of modern electronic devices, bear the crucial responsibility of connecting electronic components to form a complete circuit. Their substrates are typically made of non-conductive materials, such as plastic or fiberglass, while their surfaces are covered with conductive materials, primarily copper, to conduct current in the circuit. However, during the manufacturing process, especially after soldering various electronic components, unevenness often occurs on the surface and at the solder joints of the circuit board. This is because during soldering, the solder, after melting and cooling, solidifies, forming irregular shapes. This uneven surface not only affects the aesthetics of the circuit board but, more importantly, it brings significant difficulties to the inspection process. Traditional inspection methods... While testing equipment can detect most defects on circuit boards, it often struggles to accurately inspect uneven surfaces and solder joints. Therefore, current circuit board inspection still relies on manual spot checks. Although this method compensates for the shortcomings of automated testing equipment, it has several drawbacks. First, manual inspection consumes significant manpower and time, resulting in low efficiency. Second, manual inspection requires manual handling of the circuit board, and the results are influenced by the experience and skill level of the inspectors, easily leading to misjudgments or missed detections, thus reducing accuracy. Therefore, further improvements are needed. Utility Model Content

[0003] The main objective of this invention is to provide a detection device for identifying circuit board patterns, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A detection device for circuit board pattern recognition includes a workbench. A control keyboard is fixedly connected to the upper front end of the workbench. A base plate is fixedly connected to the upper end of the control keyboard. Clamping structures are fixedly connected to the upper left and upper right ends of the base plate, and the two clamping structures are distributed in a left-right mirror image. A push handle is fixedly connected to the middle right end of the workbench. Support legs are fixedly connected to the four corners of the lower end of the workbench, and casters are fixedly connected to the lower ends of the four support legs. A load-bearing frame is fixedly connected to the upper left and upper right ends of the workbench. A circuit board detection device is fixedly connected to the upper right end of the load-bearing frame.

[0006] The detection circuit board device includes a driver, which is fixedly connected to the right end of the load-bearing frame. The output end of the driver passes through the upper right end of the load-bearing frame and is fixedly connected to a screw rod. The left end of the screw rod is movably connected to the load-bearing frame via a bearing. A fixing block is movably connected to the outer surface of the screw rod via a thread. Limit plates are fixedly connected to both the front and rear parts of the outer surface of the fixing block. An optical sensor is fixedly connected to the lower end of the fixing block. Three high-definition cameras are fixedly connected to the outer surface of the optical sensor.

[0007] Preferably, the ends of the two limiting plates furthest from the fixed block are slidably connected to the inner upper wall of the load-bearing frame.

[0008] By adopting the above technical solution, the fixed block can be used to support the optical sensor and the high-definition camera and move with the rotation of the screw rod. The two limiting plates can ensure that the fixed block slides along the limiting groove opened on the upper wall of the load-bearing frame, which increases the stability of the movement of the fixed block.

[0009] Preferably, the three high-definition cameras are arranged in a circular array.

[0010] By adopting the above technical solution, three high-definition cameras can simultaneously capture images of the circuit board from multiple different angles, obtaining more comprehensive and three-dimensional image information of the circuit board.

[0011] Preferably, the clamping structure includes a frame, which is fixedly connected to the upper end of the base plate. The inner front wall and inner rear wall of the frame are both provided with limit grooves. A threaded push post is threadedly connected to the middle of the upper end of the frame. A pressing component is slidably connected in both limit grooves.

[0012] By adopting the above technical solution: the frame provides support and installation foundation for the entire clamping structure, the limiting groove ensures the accuracy and reliability of the clamping action, and the rotating threaded push column can push the clamping component to move up and down, thereby adjusting and controlling the clamping force.

[0013] Preferably, the clamping assembly includes a limiting block, with T-shaped grooves on the front right and rear right sides of the limiting block. Three springs are fixedly connected to the lower right side of the limiting block, and a pressure frame is fixedly connected to the ends of the three springs away from the limiting block. The inner front wall and inner rear wall of the pressure frame slide within two T-shaped grooves, respectively, and a protective pad is fixedly connected to the lower end of the pressure frame.

[0014] By adopting the above technical solution: the spring plays the role of buffering and providing elastic pressure, so that the pressure frame has a certain elastic adaptability when clamping the circuit board, avoiding rigid compression that could damage the circuit board; the protective pad prevents the pressure frame from directly contacting the circuit board and causing scratches or damage, thus protecting the circuit board.

[0015] Preferably, the front left portion and rear left portion of the limiting block slide within two limiting grooves respectively.

[0016] By adopting the above technical solution, the limiting block and the limiting groove cooperate to ensure that the entire clamping assembly moves in the limited direction, making the clamping action more reliable and accurate, and avoiding shaking or deviation.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this utility model, through the coordinated use of the driver, screw rod, fixed block and limiting plate, the driver and screw rod can accurately drive the fixed block to move smoothly, so that the fixed block can move stably along the screw rod, avoiding shaking and deviation, and ensuring the stability of the detection. The optical sensor can effectively obtain relevant information of the circuit board. The three high-definition cameras are arranged in a ring array, which can shoot from different angles to obtain more comprehensive and detailed circuit board pattern information, improve the accuracy and reliability of the detection, further enhance the adaptability and flexibility of the device, and can meet the detection needs of different types and specifications of circuit boards, and reduce the possibility of false detection and missed detection.

[0019] 2. In this utility model, by manually rotating the threaded push column, it can be moved threadedly on the frame, which can push the limiting block to slide up and down along the limiting groove. In addition, the T-shaped sliding groove on the limiting block cooperates with the pressure frame, allowing the pressure frame to slide relative to the limiting block. At the same time, three springs connect the limiting block and the pressure frame. When the limiting block is pushed, the springs apply pressure to the pressure frame. The pressure frame moves downward under the limitation of the T-shaped sliding groove, so that the pressure frame can contact the circuit board with a large area, ensuring the firmness of the clamping. The protective pad can prevent scratches and other damage to the surface of the circuit board, thus playing a protective role. Therefore, it realizes convenient and flexible clamping and fixing of the circuit board. Attached Figure Description

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A detection device for identifying circuit board patterns includes a workbench 1. A control keyboard 4 is fixedly connected to the upper front end of the workbench 1. A base plate 8 is fixedly connected to the upper end of the control keyboard 4. A clamping structure 9 is fixedly connected to the upper left and upper right ends of the base plate 8. The two clamping structures 9 are distributed in a left-right mirror image. A push handle 5 is fixedly connected to the middle right end of the workbench 1. Support legs 2 are fixedly connected to the four corners of the lower end of the workbench 1. A moving wheel 3 is fixedly connected to the lower end of each of the four support legs 2. A load-bearing frame 6 is fixedly connected to the upper left and upper right ends of the workbench 1. A circuit board detection device 7 is fixedly connected to the upper right end of the load-bearing frame 6.

[0030] In this embodiment, the circuit board detection device 7 includes a driver 71, which is fixedly connected to the right end of the load-bearing frame 6. The output end of the driver 71 passes through the upper right end of the load-bearing frame 6 and is fixedly connected to a screw rod 72. The left end of the screw rod 72 is movably connected to the load-bearing frame 6 through a bearing. A fixing block 73 is movably connected to the outer surface of the screw rod 72 by a thread. Limiting plates 74 are fixedly connected to both the front and rear parts of the outer surface of the fixing block 73. An optical sensor 75 is fixedly connected to the lower end of the fixing block 73. Three high-definition cameras 76 are fixedly connected to the outer surface of the optical sensor 75. The ends of the two limiting plates 74 away from the fixing block 73 are slidably connected to the inner upper wall of the load-bearing frame 6. The three high-definition cameras 76 are arranged in a ring array.

[0031] The above scheme works as follows: by activating the driver 71, the output of the driver 71 can drive the screw rod 72 to rotate. The screw rod 72 is connected to the fixed block 73 by a thread, so that when the screw rod 72 rotates, the fixed block 73 can move left and right along the screw rod 72. Since the limiting plates 74 fixed at the front and rear of the outer surface of the fixed block 73 are slidably connected to the inner upper wall of the load-bearing frame 6, they can play a limiting and guiding role, ensuring that the fixed block 73 can move smoothly in a straight line. An optical sensor 75 is fixed at the lower end of the fixed block 73. The optical sensor 75 can be used to sense circuit board information. Three high-definition cameras 76 arranged in a ring array are used to photograph the circuit board. They all move with the fixed block 73, so that images of the circuit board can be obtained from different positions and angles for pattern recognition and detection. This structural design realizes the function of multi-directional image acquisition and detection of the circuit board.

[0032] In this embodiment, the clamping structure 9 includes a frame 91, which is fixedly connected to the upper end of the base plate 8. The inner front wall and inner rear wall of the frame 91 are both provided with limiting grooves 92. A threaded push post 93 is threadedly connected to the middle of the upper end of the frame 91. A pressing assembly 94 is slidably connected in the two limiting grooves 92. The pressing assembly 94 includes a limiting block 941. The front right part and rear right part of the limiting block 941 are both provided with T-shaped sliding grooves 942. Three springs 943 are fixedly connected to the lower right part of the limiting block 941. The ends of the three springs 943 away from the limiting block 941 are fixedly connected to a pressure frame 944. The inner front wall and inner rear wall of the pressure frame 944 slide in the two T-shaped sliding grooves 942 respectively. A protective pad 945 is fixedly connected to the lower end of the pressure frame 944. The front left part and rear left part of the limiting block 941 slide in the two limiting grooves 92 respectively.

[0033] With the above scheme: the frame 91 is fixed to the upper end of the base plate 8, providing support for the entire clamping structure 9. By rotating the threaded push post 93, it moves threadedly on the frame 91, pushing the limiting block 941 to slide up and down along the limiting groove 92. The T-shaped slide groove 942 on the limiting block 941 cooperates with the pressure frame 944, allowing the pressure frame 944 to slide relative to the limiting block 941. At the same time, three springs 943 connect the limiting block 941 and the pressure frame 944. When the limiting block 941 is pushed, the springs 943 apply pressure to the pressure frame 944. The pressure frame 944 moves downward under the limitation of the T-shaped slide groove 942, and clamps the circuit board by pressing it with the protective pad 945. Thus, the circuit board can be detected and fixed at the same time, and the circuit board can be well protected without causing pressure damage or indentation on the surface of the circuit board.

[0034] It should be noted that this utility model is a detection device for circuit board pattern recognition. During use, firstly, four support legs 2 are fixed to the lower end of the workbench 1, and each of the four support legs 2 is fixed with a movable wheel 3 equipped with a brake function, allowing personnel to easily move the entire device to a suitable position. Simultaneously, the position can be adjusted by pushing the device using the push handle 5. The control keyboard 4 can be used to input operation commands and parameters. Then, the circuit board is placed on the base plate 8, and the left and right mirror-distributed clamping structures 9 can clamp and fix the circuit board. Specifically, the operator manually rotates the threaded push column 93 to push the limiting block 941 downwards along the limiting groove 92. Simultaneously, the spring 943 applies pressure to the pressure frame 944, causing the pressure frame 944 to pass through the protective pad 945. The circuit board is pressed firmly, and then the driver 71 is activated. The driver 71 drives the screw rod 72 to rotate. Due to the limitation of the sliding connection between the limit plate 74 and the upper inner wall of the load-bearing frame 6, the fixed block 73 can move stably left and right along the screw rod 72. The optical sensor 75 and three high-definition cameras 76 arranged in a circular array at the lower end of the fixed block 73 move accordingly. During the movement, the high-definition cameras 76 can take pictures of the circuit board from different angles, and the optical sensor 75 can sense the information of the circuit board. The acquired images and information are transmitted to the control system for pattern recognition and analysis. Therefore, the entire device can achieve efficient detection of the circuit board, which provides convenience for the inspection work of the inspection personnel and further improves the inspection efficiency of the circuit board.

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 illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
