Description
Technical Field
[0001] This invention relates to the field of PCBA testing equipment technology, specifically a fully automated testing device for PCBA production lines. Background Technology
[0002] The fully automated PCBA testing device for production lines is a piece of equipment used for automated testing of circuit boards in factories. It mainly includes a display screen, a carrier plate, a pressure plate, and a control handle. The carrier plate holds the PCBA circuit board under test, and the pressure plate integrates test probes at its bottom. The handle is linked to the pressure plate. During operation, pressing down on the handle moves the pressure plate, causing the probes to contact the test points on the PCBA board. The built-in control module automatically completes the electrical performance test, and the test results are displayed on the screen in real time. This device aims to improve testing efficiency and accuracy.
[0003] In existing technologies, to ensure precise alignment between test probes and test points on the PCBA board, a placement groove is typically created on the surface of the carrier board. This groove is slightly larger than the PCBA board and uses its sidewalls to physically restrain the board, thus preventing displacement during testing. This design ensures the alignment accuracy between the probe and the test point through mechanical constraints, thereby maintaining the reliability of the test results. However, in actual testing, the PCBA board must first be placed in the placement slot, and then the handle must be pressed to move the pressure plate downwards. Due to differences in the manual force applied by different operators, the PCBA board may slightly shift or wobble within the placement slot, affecting the contact accuracy between the probe and the test point and reducing testing accuracy. Furthermore, current placement slots are mostly recessed structures, requiring manual removal of the PCBA board after testing, which is inconvenient and limits the ease of operation of the device. Therefore, this invention proposes a fully automated PCBA testing device for production lines to solve the above problems. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1 to 11This invention provides a technical solution: a fully automatic PCBA testing device for a production line, comprising: a support box 1, a computer board for the testing device installed inside the support box 1, indicator lights and a switch button installed on the upper surface of the support box 1, the support box 1 serving as the foundation of the entire device, thus providing stable support for the entire device, one side of the upper surface of the support box 1 being fixedly connected to the bottom of a support frame 2, a pressing component being provided on one side of the top of the support frame 2, the support frame 2 supporting the pressing component, a detection component being installed below the pressing component, and the detection component being driven to test the PCBA board by operating the pressing component, a carrier plate 3 being fixedly installed on one side of the bottom of the support frame 2, a placement groove 4 being formed on the upper surface of the carrier plate 3, the carrier plate 3 supporting the PCBA board, and the placement groove 4 being U-shaped to facilitate the PCBA board sliding onto the carrier plate 3 from one side. This also facilitates the removal of the board from the open side after the board is tested, improving convenience. Pressure frames 5 are provided on opposite sides of the placement slot 4, and pressure blocks 6 are provided at the four corners of the placement slot 4, each rotatably facing inwards. Anti-slip pads 7 are fixedly installed on the top of both the pressure frames 5 and the top of the pressure blocks 6. The pressure frames 5 press and fix the middle of both ends of the PCBA board, and the pressure blocks 6 press and fix the sides of both ends of the PCBA board, thus ensuring the stability of the PCBA board during testing. A drive assembly is connected to the bottom of both the pressure frames 5 and the pressure blocks 6. The drive assembly is used to drive the pressure frames 5 to rise and fall and to drive the pressure blocks 6 to rotate. A display screen 8 is fixedly installed on the other side of the top of the support frame 2, allowing the test results to be viewed, thus facilitating subsequent processing by the operator.
[0020] In use, turn on the switch button on the support box 1, and insert the PCBA board to be tested into the U-shaped placement slot 4 through one side opening, allowing it to slide into the slot 4. The placement slot 4 provides initial positioning of the PCBA board. Then, to ensure a more stable and accurate docking of the PCBA board with the probe, the drive assembly moves the pressure frame 5 downward, pressing it towards the center of the upper surface edge of the PCBA board. At the same time, the drive assembly also drives the pressure block 6 to rotate, causing it to rotate towards both sides of the upper surface edge of the PCBA board. Thus, with the cooperation of the pressure frame 5 and the pressure block 6, the anti-slip pad 7 fixedly connected to the top of the pressure frame 5 and the pressure block 6 presses against the PCB. The edges of the A board are pressed tightly, and the anti-slip pads 7 increase friction while protecting the edges of the PCBA board to prevent damage. This also limits and fixes the PCBA board, preventing slight displacement or shaking of the PCBA board within the placement slot 4 due to differences in manual force applied by different operators when operating the pressing component. This would affect the contact accuracy between the probe and the test point and reduce the accuracy of the test. After the PCBA board is fixed in place, the pressing component is operated to move the test component closer to the PCBA board, thereby burning and testing the PCBA board. The test results are displayed on the screen 8, which is convenient for the operator to view and perform subsequent operations.
[0021] The support box 1 contains a computer board for the testing device. The test probe 17 is electrically connected to the computer board, and the computer board is electrically connected to the display screen 8. The pressing assembly includes a fixing plate 9, which is fixedly installed on the top of the support frame 2. A limiting sleeve 10 is fixedly connected to the bottom of the fixing plate 9. A pressure rod 11 is slidably fitted inside the limiting sleeve 10. The limiting sleeve 10 limits the pressure rod 11 to ensure the sliding stability of the pressure rod 11. The bottom of the pressure rod 11 is fixedly connected to the pressure plate 12. The top of the pressure rod 11 is rotatably connected to one end of the connecting plate 14 through a limiting pin 13. The other end of the connecting plate 14 is rotatably connected to one side of the bottom of the handle rod 15 through a limiting pin 13. The other side of the bottom of the handle rod 15 is rotatably connected to the fixing plate 9 through a limiting pin 13. There are two connecting plates 14, which are symmetrically arranged about the top of the pressure rod 11.
[0022] After the PCAB board to be tested is placed, press down on the handle rod 15. The upper side of one end of the handle rod 15 rotates and presses down under the limit pin 13 on the fixed plate 9. The lower side of one end of the handle rod 15 drives its upper limit pin 13 to move downward, thereby causing the connecting plate 14 to rotate under the rotational connection of its top and bottom limit pins 13. The connecting plate 14 then applies pressure to the pressure rod 11, causing the pressure rod 11 to slide downward under the limit sleeve 10. The pressure rod 11 then drives the pressure plate 12 to move downward synchronously, which facilitates the subsequent testing of the testing components. After the test is completed, the test probe 17 can be moved in the opposite direction by pulling the handle rod 15 in the opposite direction.
[0023] The testing assembly includes a probe plate 16, the upper surface of which is fixedly connected to a pressure plate 12 to facilitate synchronous movement with the pressure plate 12. Several test probes 17 are fixedly mounted on the probe plate 16, and the positions of the test probes 17 correspond to the contact points of the PCBA board. The two ends of the probe plate 16 adjacent to the support frame 2 are slidably sleeved on a large guide rod 18. The large guide rod 18 guides the probe plate 16 during its movement, thereby improving the docking accuracy of the test probes 17. The upper and lower ends of the large guide rod 18 are respectively fixedly installed in a fixed seat provided on the support frame 2, and the fixed seat limits and fixes the large guide rod 18. Several guide sleeves 19 are fixedly provided around the periphery of the probe plate 16, and a buffer 20 is coaxially connected to the bottom of each guide sleeve 19. The buffer 20 is fixedly installed on the upper surface of the support box 1.
[0024] As the pressure plate 12 moves the probe plate 16 downwards, the probe plate 16 slides downwards through the guide limit of the large guide rod 18. This guide rod 18 improves the accuracy of the contact point between the test probe 17 and the PCBA board. To prevent excessive force during the downward pressure of the probe plate 16, which could damage the test probe 17 or the PCBA board, a guide sleeve 19 is provided around the probe plate 16. Before the test probe 17 contacts the PCBA board, the guide sleeve 19 slides against the buffer 20, thus pressing the buffer 20. The reverse elastic force of the buffer 20 buffers the downward pressure of the probe plate 16, further improving the accuracy of the test probe 17's contact and preventing damage to the test probe 17 and the PCBA board, thus enhancing safety during use.
[0025] The drive assembly includes a U-shaped plate 21, with both sides of the U-shaped plate 21 slidably fitted onto a central guide rod 22. The central guide rod 22 guides the U-shaped plate 21, ensuring that the U-shaped plate 21 can slide stably along its axial direction. The bottom of the central guide rod 22 is fixedly connected to the upper surface of the support box 1. Both ends of the U-shaped plate 21 are fixed to the middle position of the bottom of the drive frame 23. The drive frame 23 is slidably installed inside one side of the support shell 24. The bottom of the support shell 24 is fixedly connected to the upper surface of the support box 1. A driven frame 25 is slidably installed inside the other side of the support shell 24. A groove is provided inside the support shell 24 to facilitate the sliding of the drive frame 23 and the driven frame 25, thereby limiting the movement of the drive frame 23 and the driven frame 25 during sliding. A compression spring 26 is fixedly connected between the upper bottom of the driven frame 25 and the lower bottom of the drive frame 23. A tension spring 27 is fixedly connected between the bottom side and the inner wall of the support shell 24. A limit block 28 is fixedly installed on one side wall inside the support shell 24. The top of the driven frame 25 is fixedly connected to the bottom of the pressure frame 5. The limit block 28 is installed on the support shell 24 near the bottom of the drive frame 23, thereby limiting the drive frame 23. A fixing pin 29 is provided on the upper side of the limit block 28. One end of the fixing pin 29 is rotatably connected to the middle of the connecting block 30, and the other end of the fixing pin 29 is fixedly sleeved inside the support shell 24. The fixing pin 29 limits the connecting block 30, thereby allowing it to rotate inside the support shell 24. Arc-shaped holes 31 are opened at both ends of the connecting block 30. One of the arc-shaped holes 31 is slidably connected to the sliding pin 32 fixedly installed on the drive frame 23, and the other arc-shaped hole 31 is slidably connected to the sliding pin 32 fixedly installed on the driven frame 25.
[0026] To prevent the PCBA board from shifting or deviating within the placement slot 4 due to shaking during the movement of the handle 15 and probe plate 16, the U-shaped plate 21 is first pressed down, causing it to slide downwards under the guidance and limitation of the guide rod 22. This causes the U-shaped plate 21 to drive the drive frame 23, which is fixedly connected to its end, to move synchronously. The drive frame 23 slides downwards under the limitation of the support shell 24, and then slides within the arc-shaped hole 31 at one end of the connecting block 30 through the sliding pin 32 installed on it. This then presses the connecting block 30 to rotate under the limitation of the fixing pin 29, causing the arc-shaped hole 31 at the other end of the connecting block 30 to pass through the driven... The sliding pins 32 installed on the frame 25 slide together, causing the driven frame 25 to slide upward under the limit of the support shell 24, thereby realizing the opposite movement between the drive frame 23 and the driven frame 25. Under the action of the opposite movement of the drive frame 23 and the driven frame 25, the compression spring 26 is compressed, while the tension spring 27 is stretched by the driven frame 25, so that the compression spring 26 and the tension spring 27 both generate opposite elastic force until the drive frame 23 abuts against the limit block 28. At this time, the pressure on the U-shaped plate 21 stops. As the driven frame 25 moves upward, it will drive the pressure frame 5 to move upward, thereby moving it away from the carrier plate 3, which facilitates the placement of the PCBA board.
[0027] The two sides of the bottom of the drive frame 23 are fixedly connected to one end of the connecting frame 33, thus facilitating the movement of the connecting frame 33. The other end of the connecting frame 33 passes through a through hole in the support base 34 and is fixedly connected to the upper surface of the connecting rod 35. The through hole in the support base 34 limits the movement of the connecting frame 33, thereby improving its stability. The support base 34 is fixedly connected between the upper surface of the support box 1 and the lower surface of the bearing plate 3, providing stable support through the support base 34 and the bearing plate 3. The connecting frame 33 is slidably mounted on a small guide rod 41 fixedly mounted on the upper surface of the support box 1, guiding the connecting frame 33 further. To improve its stability during movement along the axis of the small guide rod 41, both ends of the connecting rod 35 are rotatably connected to one end of the short rod 36 via connecting pins. The other end of the short rod 36 is fixedly connected to the middle of the triangular plate 37 via connecting pins. The bottom of the triangular plate 37 is fixedly connected to the lower limit seat 38 via connecting pins. The lower limit seat 38 is fixedly installed on the support seat 34. The top of the triangular plate 37 is rotatably connected to one end of the long rod 39 via connecting pins. The other end of the long rod 39 is rotatably connected to one side of the bottom of the pressure block 6 via connecting pins. The other side of the bottom of the pressure block 6 is rotatably connected to the upper limit seat 40 fixedly installed on the side wall of the bearing plate 3 via connecting pins.
[0028] As the drive frame 23 moves downward, it drives the connecting frame 33 to move under the limiting guidance of the small guide rod 41 and the through hole. This causes the connecting frame 33 to drive the connecting rod 35 downward. The connecting rod 35 then drives one end of the short rod 36, which is rotatably connected at both ends, to move downward through the connecting pin. The other end of the short rod 36 pulls the triangular plate 37 downward through the connecting pin. The bottom of the triangular plate 37 is rotatably connected to the lower limit seat 38 through the connecting pin, causing the triangular plate 37 to rotate downward. This causes the triangular plate 37 to drive the long rod 39 to move through the connecting pin at its top. The long rod 39 then pulls one end of the bottom of the pressure block 6 downward through the connecting pin. The other side of the bottom of the pressure block 6 is rotatably connected to the upper limit seat 40 through the connecting pin, causing the pressure block 6 to rotate away from the bearing plate 3. Finally, the pressure block 6 rotates away from the bearing plate 3. With the pressure block 6 and pressure frame 5 both far from the placement slot 4, the PCBA board can be slid into the placement slot 4 on the support plate 3. After placement, the U-shaped plate 21 is released. Under the reverse elastic force of the compression spring 26 and the tension spring 27, the drive frame 23 and the driven frame 25 move in opposite directions, causing the pressure frame 5 to move downward and the connecting frame 33 to move upward. This causes the connecting rod 35 to indirectly drive the pressure block 6 to move closer to the placement slot 4 until the anti-slip pads 7 installed on the pressure frame 5 and pressure block 6 are tightly abutted against the two sides of the upper surface edge of the PCBA board, thus fixing the PCBA board and preventing it from shaking or shifting. After the test is completed, simply press the U-shaped plate 21 again to release the pressure frame 5 and pressure block 6 from limiting the PCBA board, making it easy to remove the board.
