Description

Technical Field

[0001] This application relates to the field of flying needle testing technology, and in particular to a horizontal flying needle testing device. Background Technology

[0002] Flying probe testing is one of the methods for checking the electrical functions of a PCB board. It uses probes instead of bed-of-pin testing and is an upgrade of bed-of-pin testing. It uses multiple motor-driven electrical probes that can move quickly to contact the pins of the device and perform electrical measurements.

[0003] Currently, PCB design and manufacturing, as well as small-batch and single-piece production, have become the mainstream in the industry. Products are becoming increasingly diversified, personalized, and miniaturized, with a clear trend towards component density, leading to smaller pad diameters. In the market, flying probe testing mainly includes vertical and horizontal flying probe testing machines. Vertical flying probe testing machines can only use manual loading, affecting testing efficiency. Furthermore, vertical flying probe testing machines are slow for single- and double-sided thin PCBs, impacting not only testing speed but also machine efficiency and test results. In addition, for large-scale PCB testing using general-purpose machine tools, the high density of some test points necessitates sophisticated testing molds with high manufacturing costs, making it difficult for some machines to achieve production. Summary of the Invention

[0004] To address the issues of low testing efficiency and difficulties in mass production of PCB testing machines, this application provides a horizontal flying probe testing device.

[0005] This application provides a horizontal flying probe testing device, which adopts the following technical solution:

[0006] A horizontal flying needle detection device includes a feeding mechanism, a first detection mechanism, a flipping mechanism, a second detection mechanism, and a discharging mechanism;

[0007] The loading mechanism is used to load the PCB board to be inspected and transfer it to the first inspection mechanism. The loading mechanism includes a frame, a transport cart, a loading platform, a robot arm, a suction cup, and a transmission component. The transmission component is mounted on the frame, and the loading platform is slidably mounted on the transmission component to carry the PCB board to be inspected. The transport cart is used to transport the loading platform to the transmission component.

[0008] The first inspection mechanism is used to inspect the front side of the PCB board conveyed by the feeding mechanism.

[0009] The flipping mechanism is used to flip the PCB board after it has been inspected by the first inspection mechanism.

[0010] The second inspection mechanism is used to inspect the flipped PCB board, i.e., the reverse side of the PCB board;

[0011] The unloading mechanism is used to unload the PCB boards that have completed inspection.

[0012] By adopting the above technical solution, when testing is required, the PCB board to be tested is first transported to the first testing mechanism via the loading mechanism for electrical testing of the front side of the PCB board. Then, the first testing mechanism continues to convey the tested PCB board to the flipping mechanism, which flips the front side of the PCB board 180 degrees to obtain the back side PCB board. Then, it is transported to the second testing mechanism for electrical testing of the back side PCB board. Finally, the unloading mechanism unloads and stores the PCB board that has been tested on both sides, and continues to conduct subsequent PCB board testing. This realizes the horizontal testing design of PCB boards and double-sided testing of PCB boards. The automated operation not only improves testing efficiency but also reduces manual intervention, lowers labor intensity and labor costs, and improves machine utilization efficiency to enhance testing results. In addition, it can also realize the testing of batch PCB boards, which has great practical value.

[0013] In the loading process, the material transport cart is first pushed to one side of the transmission component, and the loading platform is placed on the cart. The cart is then transported to the previous process stage to receive the materials to be tested. Next, the cart, now full of materials, is pushed to the transmission component, and the loading platform and PCB boards are all pushed onto it. A positioning component limits the loading platform to prevent slippage. Then, a robotic arm uses suction cups to adaptively vacuum-adhere the PCB boards, transferring them to the first testing unit for subsequent testing. This automated loading process improves efficiency, reduces manual intervention, and lowers the workload and labor costs for testing personnel.

[0014] Preferably, the conveying component includes a first roller and a mounting frame, the mounting frame being disposed on the frame, and the first roller and the mounting frame being rotatably connected; the feeding mechanism further includes a storage component, the storage component including a bracket and a second roller, the bracket being located on one side of the frame, and the second roller being rotatably connected to the bracket.

[0015] By adopting the above technical solution, the first roller can both support the material carrier and slide against it, reducing friction during the material carrier's pushing process. The second roller is designed to both support and transport the PCB board. This multi-functional design enhances practicality.

[0016] Preferably, the frame is further provided with a locking assembly, which is used to lock the material conveyor.

[0017] The vehicle locking assembly includes a guide wheel, an elastic element, a first connecting member, a locking member, and a cylinder. The first connecting member is mounted on the frame. The guide wheel, elastic element, locking member, and cylinder are all mounted on the first connecting member. The elastic element is connected to the first connecting member via a spring. The locking member includes a swing arm hook and a fixed arm. The fixed arm is fixedly mounted on the lower surface of the first connecting member. The swing arm hook is rotatably connected to the first connecting member. The swing arm hook and the elastic element are used to fix the fixing rod of the material transport vehicle. The end of the swing arm hook away from the fixed arm is connected to the cylinder via a second connecting member.

[0018] By adopting the above technical solution, during loading, the guide wheel restricts the material to a suitable position. The fixed rod pushes open the swing arm hook and enters between the swing arm hook and the fixed arm. Due to the connection between the elastic element and the spring, when the fixed rod enters, it compresses the spring, and the elastic element presses the fixed rod tightly in that position. After the conveying is completed, the cylinder drives the second connecting piece to move, thereby causing the swing arm hook to rotate. The fixed rod of the material transport vehicle is pushed out under the action of the spring. This achieves the locking mechanism to lock the material transport vehicle, thereby improving the stability of loading.

[0019] Preferably, the feeding mechanism further includes a positioning component, which includes a fixing plate and a positioning rod. The fixing plate is disposed on one side of the transmission component, and the positioning rod is rotatably connected to the fixing plate to limit the loading platform on the transmission component.

[0020] By adopting the above technical solution, after the material carrier is pushed onto the transmission component, the positioning rod is moved to hold the rear of the material carrier in place to prevent it from slipping, thereby improving the stability of subsequent adsorption and transfer.

[0021] Preferably, the first detection mechanism includes a guide assembly, a worktable, a conveyor belt, an XY-axis guide rail, a detection component, and a motor. The guide assembly is disposed between the transmission assembly and the worktable for guiding the transmission of the PCB board. The motor and the conveyor belt are both disposed on the worktable, and the motor drives the conveyor belt. A support plate is disposed between the two conveyor belts, and the support plate is fixedly connected to the worktable. The XY-axis guide rail is fixedly disposed on the worktable, and the detection component is disposed on the XY-axis guide rail. Guide plates are also disposed on both sides of the worktable for guiding the transmission of the PCB board.

[0022] By adopting the above technical solution, when the PCB board is conveyed to the first inspection mechanism, it is first received by the guide component and guided in the direction of conveying. The PCB board enters the conveyor belt, and the conveyor belt transports it to the appropriate position. The inspection component performs comprehensive electrical inspection on the PCB board through the XY axis guide rail. The guide plate is set to ensure that the PCB board is located on the conveyor belt track and will not affect the subsequent conveying and inspection, thereby realizing the process of front-side inspection of the PCB board.

[0023] Preferably, the guiding assembly includes a guide bracket, a receiving component, a guide rod, and a driving component. The guide rod is disposed on the guide bracket, the receiving component passes through the guide rod, and the driving component is disposed on the guide bracket for driving the receiving component to slide on the guide rod.

[0024] By adopting the above technical solution, after the PCB board is transferred by the storage component, it is received by the receiving component. The driving component can adjust the position of the receiving component on the guide rod to adapt to PCB boards of different sizes.

[0025] Preferably, the receiving component includes a receiving plate and a limiting plate. The receiving plate is fixedly mounted on the guide rod. The receiving plate has an inclined surface on the side near the feeding mechanism. The limiting plate is connected to the driving component and is used to limit the PCB board located on the receiving plate.

[0026] By adopting the above technical solution, the receiving plate is used to support the PCB board. The PCB board is first moved from one side of the inclined plane to the plane of the receiving plate, which also plays a guiding role in the movement of the PCB board. The setting of the limiting plate can adapt to PCB boards of different sizes and limit and guide the PCB board located on the receiving plate.

[0027] Preferably, the limiting plate includes a fixed limiting plate and a movable limiting plate. The fixed limiting plate is fixedly mounted on the guide rod, and the movable limiting plate is connected to the driving component. The driving component includes a driving motor and a limiting conveyor belt. The limiting conveyor belt is fixedly connected to the movable limiting plate, and the driving motor is used to drive the limiting conveyor belt.

[0028] By adopting the above technical solution, when adjusting the position between the fixed limiting plate and the moving limiting plate, the fixed limiting plate remains stationary, and the limiting conveyor belt is driven by the drive motor to move the moving limiting plate, thereby controlling the distance between the fixed limiting plate and the moving limiting plate.

[0029] Preferably, the flipping mechanism includes a flipping bracket, a flipping wheel assembly, and a flipping motor. The flipping wheel assembly is rotatably disposed within the flipping bracket and is configured in two layers for flipping the PCB board to obtain the reverse side of the PCB board. The flipping motor is used to drive the flipping wheel assembly to flip.

[0030] By adopting the above technical solution, the PCB board output by the first detection mechanism enters the flipping wheel group. The two layers of flipping wheel group play a role in pressing and positioning the PCB board. Then, the flipping motor drives the flipping wheel group to rotate 180 degrees, thus obtaining the reverse side of the PCB board.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. By connecting multiple machines in a line, automated PCB board inspection is achieved, featuring a horizontal inspection design and double-sided inspection of PCBs. Automation not only improves inspection efficiency but also reduces manual intervention, lowering labor intensity and costs, and enhancing machine utilization to improve testing results. Furthermore, the horizontal inspection design enables batch inspection of PCBs, making it highly practical. The automated feeding design also reduces the workload and costs for inspection personnel. The adaptive vacuum suction cups improve the stability and transport efficiency of the robotic arm during gripping and transfer. Other component designs embody the concept of multi-purpose functionality, enhancing practicality.

[0033] 2. During loading, the guide wheel restricts the material to a suitable position, the fixing rod pushes the swing arm hook open, and then the swing arm hook and elastic element are fixed. After the transfer is completed, the cylinder drives the swing arm hook to rotate through the second connecting part, and the fixing rod of the material transport vehicle is pushed out under the action of the spring, thereby realizing the locking mechanism to lock the material transport vehicle and improving the stability of loading.

[0043] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0044] This application discloses a horizontal flying needle detection device. (Refer to...) Figure 1 It includes a feeding mechanism 1, a first inspection mechanism 2, a tilting mechanism 3, a second inspection mechanism 4, and a discharging mechanism 5.

[0045] Reference Figure 2The loading mechanism 1 is used to load the PCB board to be inspected and transfer it to the first inspection mechanism 2. The loading mechanism 1 includes a frame 11, a transport cart 12, a loading platform 13, a robot arm 14, a suction cup 15 and a transmission component 16. The transmission component 16 is set on the frame 11, and the loading platform 13 is slidably set on the transmission component 16 to carry the PCB board to be inspected. The transport cart 12 is used to transport the loading platform 13 and the PCB board to the transmission component 16.

[0046] The first inspection unit 2 is used to inspect the front side of the PCB board conveyed by the feeding unit 1.

[0047] The flipping mechanism 3 is used to flip the PCB board after it has been inspected by the first inspection mechanism 2;

[0048] The second inspection unit 4 is used to inspect the flipped PCB board, i.e., the reverse side of the PCB board;

[0049] The unloading mechanism 5 is used to unload the PCB boards that have completed inspection.

[0050] When flying probe testing is required, the PCB board to be tested is first automatically fed by the feeding mechanism 1. Then, the PCB board is transferred to the first testing mechanism 2 for electrical testing. Next, the flipping mechanism 3 flips the PCB board to obtain the reverse side of the PCB board. The second testing mechanism 4 performs electrical testing on the reverse side of the PCB board. Finally, the unloading mechanism 5 unloads and stores the tested PCB board, thus realizing the automated testing process of horizontal flying probe testing, improving testing efficiency, reducing manual intervention, and lowering labor intensity and costs. In the PCB board loading process, the material transport cart 12 is first pushed onto the transmission component 16 by a person, and the material carrier 13 is placed on the material transport cart 12. Then, the material transport cart 12 is pushed to the previous process to receive the material to be tested. The material transport cart 12 is then transported to the transport component, and the material carrier 13 and the PCB board are pushed onto the transmission component 16 and limited by the positioning component 18. Then, the robot arm 14 drives the suction cup 15 to perform adaptive vacuum adsorption on the PCB board to be tested and transfer the PCB board to the first testing mechanism 2 for the next operation process.

[0051] Specifically, refer to Figure 2 The transmission assembly 16 includes a first roller 161 and a mounting frame 162. The mounting frame 162 is fixedly mounted on the frame 11. The first roller 161 and the mounting frame 162 are rotatably connected. There are several first rollers 161, and the transmission assembly 16 has two sets. The feeding mechanism 1 also includes a positioning assembly 18. The positioning assembly 18 includes a fixing plate 181 and a positioning rod 182. The fixing plate 181 is disposed on one side of the mounting frame 162, and the positioning rod 182 is rotatably connected to the fixing plate 181.

[0052] When the loading platform 13 is idle, it can be placed on one of the first rollers 161 and positioned by the positioning rod 182 to prevent it from slipping. When the transport vehicle 12 transports the loading platform 13 filled with the material to be tested, it is received by the first rollers 161 of another set and moved to a suitable position. Then, the positioning rod 182 is rotated to the rear of the loading platform 13 to position it and prevent it from slipping, thereby improving the stability of subsequent gripping.

[0053] Reference Figure 3 The feeding mechanism 1 also includes a storage component 17, which includes a support 171, a second roller 172, and a sensor 173. The support 171 is located on one side of the frame 11, and the second roller 172 is rotatably connected to the support 171. There are several second rollers 172. The sensor 173 is mounted on the support 171 and located directly above the second roller 172. When the robot arm 14 drives the suction cup 15 to place the PCB board on the second roller 172, the sensor 173 detects that a PCB board has been placed on it. Then, the second roller 172 starts and conveys the PCB board to the first detection mechanism 2 for detection.

[0054] Reference Figure 4 and Figure 5 The frame 11 is also provided with a locking assembly 19 for locking the material transport vehicle 12. The locking assembly 19 includes a guide wheel 191, an elastic element 192, a first connecting member 193, a locking member 194, and a cylinder 195. The first connecting member 193 is mounted on the frame 11. The guide wheel 191, the elastic element 192, the locking member 194, and the cylinder 195 are all mounted on the first connecting member 193. The elastic element 192 is connected to the first connecting member 193 by a spring 198. The locking member 194 includes a swing arm hook 1941 and a fixed arm 1942. The fixed arm 1942 is fixedly mounted on the lower surface of the first connecting member 193. The swing arm hook 1941 is rotatably connected to the first connecting member 193. The swing arm hook 1941 and the elastic element 192 are used to fix the fixing rod 197 of the material transport vehicle 12. The end of the swing arm hook 1941 away from the fixed arm 1942 is connected to the shaft of the cylinder 195 by a second connecting member 196.

[0055] When the material transport vehicle 12 is pushed to one side of the second roller 172, the guide wheel 191 restricts the material transport vehicle 12 from moving forward, causing the material transport vehicle 12 to stop at a suitable position. The fixing rod 197 of the material transport vehicle 12 pushes open the swing arm hook 1941 and enters between the swing arm hook 1941 and the fixing arm 1942. Since the end of the elastic element 192 away from the guide wheel 191 is connected to the spring 198, the spring 198 is compressed after the material transport vehicle 12 enters, so that the fixing rod 197 of the material transport vehicle 12 is pressed at this position. After the conveying is completed, the cylinder 195 drives the swing arm hook 1941 to rotate through the second connecting member 196. The fixing rod 197 of the material transport vehicle 12 is pushed out under the action of the spring 198, thereby realizing the locking effect of the material transport vehicle 12 to improve the stability of the material loading.

[0056] Reference Figure 6 The first testing mechanism 2 includes a guide assembly 21, a worktable 22, a conveyor belt 23, an XY-axis guide rail 24, and a testing component 25. The guide assembly 21 is disposed between the support 171 and the worktable 22, with the worktable 22 located on one side of the guide assembly 21. The conveyor belt 23 is rotatably connected to the worktable 22, and a support plate 27 is disposed between the two conveyor belts 23. The support plate 27 is fixedly connected to the worktable 22. The XY-axis guide rail 24 is disposed on the worktable 22, and the testing component 25 is fixedly disposed on the XY-axis guide rail 24 to perform full-range electrical testing on the PCB board. Guide plates 26 are disposed on both sides of the worktable 22, near the outermost conveyor belt 23, and are inclined.

[0057] When testing is required, the testing component 25 moves in its entirety via the XY axis guide rail 24 to perform testing. The guide plate 26 is designed to guide the PCB board to the correct track if it deviates from the transport track, thereby improving the accuracy of testing and the sustainability and efficiency of transport.

[0058] Specifically, refer to Figure 7The guide assembly 21 includes a guide bracket 211, a receiving component 212, a guide rod 213, and a drive component 214. The receiving component 212 includes a receiving plate 2121 and a limiting plate 2122. The limiting plate 2122 further includes a limiting fixed plate 2123 and a limiting moving plate 2124. The drive component 214 includes a drive motor 2141 and a limiting conveyor belt 2142. The guide bracket 211 is located on one side of the bracket 171. The guide rod 213 and the guide bracket 211 are fixedly connected. 21 is fixed on the guide bracket 211. The receiving plate 2121 has an inclined surface on the side near the bracket 171. The limiting plate 2123 is fixed on the guide bracket 211. The limiting moving plate 2124 slides on the guide bracket 211. The limiting moving plate 2124 and the limiting conveyor belt 2142 are fixedly connected. The receiving plate 2121 is located between the limiting plate 2123 and the limiting moving plate 2124. The drive motor 2141 is set on the guide bracket 211 and is used to drive the limiting conveyor belt 2142.

[0059] When the PCB board to be inspected is conveyed, it is slowly conveyed onto the receiving plate 2121 via the inclined surface of the receiving plate 2121. The position of the limiting plate 2123 remains unchanged. The limiting conveyor belt 2142 is driven by the drive motor 2141. The limiting conveyor belt 2142 drives the limiting moving plate 2124 to move closer to or away from the receiving plate 2121 to limit the PCB board. Thus, the limiting effect of PCB boards of different sizes can be achieved by adjusting the position of the limiting moving plate 2124.

[0060] Reference Figure 8 The flipping mechanism 3 includes a flipping bracket 31, a flipping wheel assembly 32, and a flipping motor 33. The flipping bracket 31 is located on one side of the first detection mechanism 2. The flipping wheel assembly 32 is rotatably connected to the flipping bracket 31. The fixing member 34 is set on the flipping wheel assembly 32. The flipping wheel assembly 32 includes two layers. When the PCB board inspected by the first detection mechanism 2 is transported over, it enters between the two layers of the flipping wheel assembly 32. The two layers of the flipping wheel assembly 32 will play a role in pressing and positioning the PCB board. Then, the flipping motor 33 is started to flip the entire flipping wheel assembly 32 180 degrees. Then, the PCB board on the reverse side is transported to the second detection mechanism 4 for inspection.

[0061] The second inspection mechanism 4 has the same structure as the first inspection mechanism 2 and is used to inspect the electrical connections on the reverse side of the PCB board. The unloading mechanism 5 has the same structure as the loading mechanism 1 and is used to unload and collect the PCB boards after the front and back inspections are completed. This completes one PCB board loading / unloading and front and back inspection cycle.

[0062] The implementation principle of a horizontal flying probe testing device in this application embodiment is as follows: When electrical testing of a PCB board is required, the material transport cart 12 is first transported to one side of the frame 11, the material board placed on the first roller 161 is placed on the material transport cart 12, and then the material transport cart 12 is transported to the previous process to prepare to receive the material to be tested.

[0063] Then, the material transport cart 12 filled with the material to be tested is pushed to one side of the first roller 161 of another group. The guide wheel 191 stops the material transport cart 12 in the appropriate position. The fixing rod 197 of the material transport cart 12 pushes open the swing arm hook 1941 and enters between the swing arm hook 1941 and the fixing arm 1942. The spring 198 is compressed. Then the elastic element 192 presses the fixing rod 197 in the position, and the material transport cart 12 is locked. Next, the loading platform 13 together with the PCB board is pushed onto the first roller 161 of another group. The positioning rod 182 is moved to limit the loading platform 13 on the first roller 161 to prevent it from slipping.

[0064] After the loading is completed, the cylinder 195 drives the swing arm hook 1941 to rotate through the second connector 196. The fixed rod 197 of the material transport vehicle 12 is pushed out under the action of the spring 198, and the material transport vehicle 12 can be moved away for the next loading. Then the robot arm 14 drives the suction cup 15 to perform adaptive adsorption and transfer the PCB board to the second roller 172. After the sensor 173 senses that there is a PCB board on the second roller 172, the second roller 172 starts to roll and convey the PCB board.

[0065] Next, the drive motor 2141 drives the limiting conveyor belt 2142 to move, thereby moving the limiting moving plate 2124 and adjusting the distance between the limiting fixed plate 2123 and the limiting moving plate 2124 to a suitable distance. Then, the PCB board conveyed by the second roller 172 gradually moves to the plane of the receiving plate 2121 through the inclined surface of the receiving plate 2121. The limiting fixed plate 2123 and the limiting moving plate 2124 limit the PCB board. The second roller 172 continues to convey, and the PCB board enters the conveyor belt 23 to a suitable position. The detection component 25 realizes the electrical detection of the entire PCB board through the movement of the XY axis guide rail 24. The guide plate 26 on the worktable 22 can also guide the conveying direction of the PCB board.

[0066] Then the PCB board enters between the two layers of flipping wheel sets 32 at the flipping mechanism 3. The flipping motor 33 drives the two layers of flipping wheel sets 32 to rotate 180 degrees to obtain the reverse side of the PCB board. The flipping wheel sets 32 continue to roll to convey the reverse side of the PCB board to the second detection mechanism 4 for electrical testing.

[0067] Finally, the unloading mechanism 5 unloads and stores the inspected PCB boards, thus completing one inspection and unloading process. This process is repeated to perform electrical testing on batches of PCB boards.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
