Description

Technical Field

[0001] The utility model relates to the technical field of PCB board production, in particular to a positioning detection device for PCB boards. Background Art

[0002] A PCB is a fundamental component used to support and connect electronic components. It's typically made of insulating material, covered with conductive copper foil and printed with circuit wiring patterns. It serves a dual purpose in electronic devices, both as a mechanical support and an electrical connection. It provides a reliable platform for connecting electronic components like resistors, capacitors, and integrated circuits to form complex circuit functions. During PCB fabrication, various process steps like etching and plating require accurate position information to ensure each process step is correctly applied to the intended location. Positioning detection devices ensure that each PCB is positioned correctly for each processing step on the automated assembly line, playing a crucial role in PCB fabrication.

[0003] Traditional positioning devices usually consist of a mechanical structure and a sensor system. The mechanical structure includes a fixture, fixed table or mobile platform to support and position the PCB board, and the sensor system includes an optical sensor, mechanical switch or contact sensor to detect the positioning marks or features on the PCB board.

[0004] However, the structure of traditional positioning devices is relatively simple. They can often only position PCB boards of specific sizes and shapes, and cannot adapt to PCB boards of different shapes and sizes. As a result, when processing PCB boards of different sizes, the clamping system of the positioning device needs to be adjusted. This process is relatively cumbersome and affects processing efficiency. Therefore, a positioning detection device for PCB boards is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment of a positioning detection device for a PCB board, comprising an adjusting seat 1 and a base plate 14, wherein the top of the adjusting seat 1 is fixedly connected to a fixing frame 2, the top of the fixing frame 2 is fixedly connected to a positioning seat 3, the inside of the fixing frame 2 is fixedly connected to a motor 4, the output end of the motor 4 is fixedly connected to a rotating rod 5, the inside of the fixing frame 2 is fixedly connected to a first slide rail 6, the outer wall of the first slide rail 6 is slidably connected to a first clamping block 7, one side of the first clamping block 7 is fixedly connected to a first connecting block 8, one side of the rotating rod 5 is rotatably connected to the outer wall of the first connecting block 8, the inside of the fixing frame 2 is fixedly connected to a second slide rail 9, the outer wall of the second slide rail 9 is slidably connected to a slider 10, one side of the slider 10 is fixedly connected to the second connecting block 11, the other side of the rotating rod 5 is rotatably connected to the outer wall of the second connecting block 11, one side of the slider 10 is fixedly connected to the second clamping block 12, the top of the positioning seat 3 is fixedly connected to a stopper 13, and a support assembly is provided on the top of the base plate 14, which is used to support the adjusting seat 1 for rotation.

[0033] Specifically, when testing a PCB, the PCB is first placed above the positioning seat 3. Subsequently, the motor 4 drives the rotating rod 5 to rotate through its output end. The movement of the rotating rod 5 guides the movement of the second connecting block 11 connected to one side. The second connecting block 11 then pushes the connected slider 10 to slide on the outer wall of the second slide rail 9. The movement of the slider 10 further drives the second clamping block 12 connected to one side to slide within the fixed frame 2. At the same time, the movement of the rotating rod 5 also causes the first clamping block 7 connected to the other side to move on the outer wall of the first slide rail 6. Through the coordinated movement of the second clamping block 12 and the first clamping block 7, the PCB is clamped and fixed above the positioning seat 3, thereby achieving rapid and precise positioning of PCBs of different sizes, ensuring that they remain stable and in the correct position during the testing process, thereby ensuring the accuracy and reliability of the test results.

[0034] Reference Figure 1 and Figure 4 A support frame 15 is fixedly connected to the top of the base plate 14, and a threaded column 16 is rotatably connected inside the support frame 15. One end of the threaded column 16 is fixedly connected to a crank 17. The outer wall of the threaded column 16 is threadedly connected to a transmission block 18, and the side wall of the transmission block 18 is fixedly connected to a sliding column 19. A slide groove 20 is opened inside the support frame 15, and the sliding column 19 is slidably connected inside the slide groove 20.

[0035] Specifically, when conducting PCB board inspection, if its angular position needs to be adjusted, it can be achieved by turning the crank 17. When the crank 17 is turned, it is forced to drive the threaded column 16 to rotate inside the transmission block 18. Using the threaded relationship between them, the transmission block 18 moves accordingly. The movement of the transmission block 18 then drives the sliding column 19 connected to the side wall to slide inside the slide groove 20, achieving the effect of motion transmission.

[0036] Reference Figure 1 and Figure 4 The support assembly includes a support plate 24 and a support column 25. The support plate 24 is fixedly connected to the top of the base plate 14, the support column 25 is fixedly connected to the inside of the support plate 24, the adjustment seat 1 is rotatably connected to the outer wall of the support column 25, the outer wall of the sliding column 19 is rotatably connected to the connecting rod 21, the inside of the connecting rod 21 is rotatably connected to the connecting column 22, the outer wall of the connecting column 22 is fixedly connected to the connecting plate 23, and the top of the connecting plate 23 is fixedly connected to the bottom of the adjustment seat 1.

[0037] Specifically, the sliding column 19 pushes the connecting rod 21 connected to the outer wall to move, and the movement force of the connecting rod 21 is transmitted to the connecting column 22 connected to the inside. The connecting column 22 moves the connecting plate 23 connected to the outer wall. The movement of the connecting plate 23 affects the adjustment seat 1 connected to the top. One side of the adjustment seat 1 rotates on the outer wall of the support column 25. At the same time, the adjustment seat 1 drives the positioning assembly connected to the top, so that it can accurately adjust the angular position of the PCB board, ensuring that the angle of the PCB board can be flexibly and accurately adjusted during the detection process, ensuring the accuracy and reliability of the detection results.

[0038] Working principle: When inspecting the PCB board, first place the PCB board on top of the positioning seat 3, then drive the rotating rod 5 to rotate through the output end of the motor 4, and the rotating rod 5 is driven by the force to drive the second connecting block 11 connected on one side to move, and the second connecting block 11 is driven by the force to drive the slider 10 connected on one side to slide on the outer wall of the second slide rail 9, and the slider 10 is driven by the force to drive the second clamping block 12 connected on one side to slide inside the fixed frame 2, and at the same time, the rotating rod 5 will also drive the first clamping block 7 connected on the other side to move on the outer wall of the first slide rail 6, and the PCB board above the positioning seat 3 is clamped and fixed through the movement of the second clamping block 12 and the first clamping block 7, thereby achieving the effect of quickly positioning PCB boards of different sizes. During the inspection process, the angular position of the PCB board needs to be adjusted During the process of cutting, the crank 17 can be turned so that the threaded column 16 is driven by force to rotate inside the transmission block 18. The transmission block 18 moves through the threaded relationship between the threaded column 16 and the transmission block 18. The transmission block 18 is driven by force to drive the sliding column 19 connected to the side wall to slide inside the slide groove 20. The sliding column 19 is driven by force to drive the connecting rod 21 connected to the outer wall to move. The connecting rod 21 is driven by force to drive the internally connected connecting column 22 to move. The connecting column 22 is driven by force to drive the connecting plate 23 connected to the outer wall to move. The connecting plate 23 is driven by force to drive the adjusting seat 1 connected to the top to move, so that one side of the adjusting seat 1 is driven by force to rotate on the outer wall of the support column 25. At the same time, the adjusting seat 1 drives the positioning assembly connected to the top to move, thereby achieving the effect of adjusting the detection angle of the PCB board.
