Description

Technical Field

[0001] The utility model relates to, but is not limited to, the technical field of intelligent manufacturing test equipment, and in particular to a circuit unit test equipment. Background Art

[0002] With the rapid development of technology, intelligent devices have become an integral part of modern life. These devices generally rely on integrated circuit boards (PCBs) to realize their diverse functions. As core components in electronic devices, the stability and reliability of PCBs directly impact the performance of the entire device and the user experience. Therefore, rigorous testing and quality control of PCBs are particularly important.

[0003] During the integrated circuit board (IC) production process, both blank boards and finished boards with integrated circuits soldered on require continuity testing (i.e., IC functionality testing) to ensure the connectivity of all wiring and the overall performance of the circuit board. However, most production lines currently still rely on manual testing. This method requires workers to manually place the circuit board on a jig on a testing platform, position it using pins, and then manually press it together for testing. After the test is complete, workers must visually determine whether the circuit board has passed the test based on the test results. While manual testing can meet production needs to a certain extent, it has significant drawbacks. First, manual testing requires workers to work continuously, which is extremely physically and mentally demanding and can easily lead to fatigue and misjudgment. Second, manual testing is inefficient and cannot meet the efficiency and automation requirements of modern intelligent production lines. Furthermore, manual testing suffers from poor consistency and high costs, hindering the long-term development of enterprises. Summary of the Invention

[0025] During the integrated circuit board (IC) production process, both blank boards and finished boards with integrated circuits soldered on require continuity testing (i.e., IC functionality testing) to ensure the connectivity of all wiring and the overall performance of the circuit board. However, most production lines currently still rely on manual testing. This method requires workers to manually place the circuit board on a jig on a testing platform, position it using pins, and then manually press it together for testing. After the test is complete, workers must visually determine whether the circuit board has passed the test based on the test results. While manual testing can meet production needs to a certain extent, it has significant drawbacks. First, manual testing requires workers to work continuously, which is extremely physically and mentally demanding and can easily lead to fatigue and misjudgment. Second, manual testing is inefficient and cannot meet the efficiency and automation requirements of modern intelligent production lines. Furthermore, manual testing suffers from poor consistency and high costs, hindering the long-term development of enterprises.

[0026] In view of this, the utility model provides a circuit unit testing device that integrates a loading unit, a scanning unit, a testing unit and a unloading unit, and the loading unit, the scanning unit, the testing unit and the unloading unit are installed on the machine base in sequence. By performing automated loading, scanning, testing and unloading processes on the machine base of the device, the waiting time and operation time of manual operation are greatly reduced, thereby significantly improving the testing efficiency of the circuit board and reducing labor costs. Secondly, since the reliance on manual operation is reduced, the test accuracy can be improved and production safety can be enhanced. In addition, the utility model adopts advanced scanning and testing technology, which can accurately obtain the information of the circuit board and perform precise testing. Compared with manual detection, the consistency and accuracy of the equipment test are higher, which can reduce the error rate and improve product quality. In summary, the utility model significantly improves test efficiency, reduces labor costs, improves test accuracy, enhances production safety, and has a high degree of flexibility through automated and intelligent design, thereby meeting the needs of modern intelligent production lines for efficient and automated circuit board testing equipment.

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of the circuit unit testing equipment provided by the present invention. The circuit unit testing equipment includes a loading unit 110, a scanning unit 120, a testing unit 130, a unloading unit 140 and a machine base 150. The loading unit 110, the scanning unit 120, the testing unit 130 and the unloading unit 140 are sequentially mounted on the machine base 150, forming a complete set of automated testing systems. Among them, the loading unit 110 can store and transport the circuit board to be tested; the scanning unit 120 can accurately scan and identify the relevant information of the circuit board; the testing unit 130 can perform a qualification test on the circuit board to be tested based on the relevant information and obtain the test results; the unloading unit 140 can unload the circuit board to be tested based on the test results. Through the automated loading, scanning, testing and unloading processes, not only the waiting time and actual operation time of manual operation are greatly reduced, but also the testing efficiency of the circuit board is significantly improved, while also effectively reducing labor costs.

[0029] In a feasible embodiment, the loading unit 110 includes a first conveying assembly, which includes a first conveying track and a second conveying track. The first conveying track and the second conveying track are parallel and arranged along the left and right directions of the machine base 150, ensuring that the circuit board to be tested can be stably and efficiently transferred to the designated position (such as the scanning unit 120, the testing unit 130 and the unloading unit 140), thereby improving the working efficiency and reliability of the loading unit 110.

[0030] In a possible embodiment, if Figure 2 As shown, the loading unit 110 also integrates a first lifting structure 210, a first stacking tray structure 220 and a dropping tray structure 230. Among them, the first lifting structure 210 is installed at the bottom of the loading unit 110, the first stacking tray structure 220 is arranged on the first lifting structure 210, and the dropping tray structure 230 is located at the input end of the first conveying assembly. Specifically, the first lifting structure 210 can eject the loading tray from the first stacking tray structure 220 through a lifting action, so that it corresponds to the position of the dropping tray structure 230, preparing for the transportation of the circuit board to be tested. The first stacking tray structure 220 can be used to store multiple loading trays, which can be used to place the circuit boards to be tested. It can be understood that the first stacking tray structure 220 allows the circuit boards to be tested to remain orderly during storage, ensuring the orderliness and manageability of the circuit boards to be tested before testing, and facilitating subsequent processing and transportation. When a circuit board needs to be tested, the first lifting structure 210 ejects the carrier from the first stacking structure 220. The carrier then moves precisely to a position corresponding to the drop tray structure 230. The drop tray structure 230 then stably places the carrier at the input of the first conveyor assembly, ensuring smooth delivery of the test circuit boards and subsequent operations. This process automates the storage, preparation, and delivery of circuit boards, significantly reducing waiting time and operation time associated with manual operation, thereby significantly improving circuit board testing efficiency and reducing labor costs.

[0031] In a feasible embodiment, limit bars 240 are provided on the first conveying track and the second conveying track. These limit bars 240 not only ensure the stability and accuracy of the circuit board to be tested during the conveying process, but also prevent the circuit board to be tested from deflecting or sliding during the transmission process, thereby further improving the reliability and efficiency of the entire testing process.

[0032] In one feasible embodiment, the first conveyor assembly includes a stopper 250 positioned midway between the first and second conveyor tracks. Stopper 250 ensures that the carrier tray carrying the circuit boards to be tested maintains a stable trajectory during transport, effectively preventing damage or delays caused by accidental collisions or collisions, thereby significantly improving the smoothness and safety of the entire testing process.

[0033] In a feasible embodiment, the stopper 250 is typically made of a wear-resistant, high-hardness material, such as stainless steel or engineering plastic, to enhance its wear resistance and durability. Furthermore, the size and shape of the stopper 250 can be designed based on the specific size and shape of the loading tray to ensure that they fit snugly without obstructing the normal movement of the loading tray.

[0034] In a feasible embodiment, the unloading unit 140 includes a gripper assembly 310 and a second conveyor assembly 320, wherein the gripper assembly 310 is located on one side of the second conveyor assembly 320, wherein the gripper assembly 310 can transport qualified circuit boards to the second conveyor assembly 320 according to the test results. Specifically, after the scanning unit 120 scans the circuit boards to be tested on the loading tray and determines the information of the circuit boards (such as the signal line connection status and pin status of the circuit boards), the testing unit 130 can test the circuit boards to be tested based on this information, and classify these circuit boards into qualified products (good products) and defective products according to the test results. Then, the gripper assembly 310 will transport the qualified circuit boards (qualified products) to the second conveyor assembly 320 to ensure that these qualified circuit boards can smoothly enter the packaging process for subsequent distribution and application.

[0035] In one feasible embodiment, the equipment includes an empty tray recovery unit 330, which can be installed on the underside of the unloading unit 140 to efficiently collect the empty trays left behind after the unloading unit 140 completes the circuit board transfer. Specifically, after the gripper assembly 310 transfers qualified circuit boards from the loading tray to the second conveyor assembly 320, the remaining empty trays are transferred to the empty tray recovery unit 330 along with the movement of the first conveyor assembly. The empty tray recovery unit 330 can receive and organize these empty trays, ensuring the continuity of the production process and a clean working environment.

[0036] In one feasible embodiment, the empty tray recovery unit 330 includes a second lifting structure 340 and a second tray stacking structure 350, which is mounted on top of the second lifting structure 340. The two structures work together to efficiently recover empty trays. When an empty tray needs to be recovered, the second lifting structure 340 precisely adjusts the position of the second tray stacking structure 350 to ensure that it precisely aligns with the empty tray, thereby smoothly stacking and recovering the empty trays.

[0037] In a feasible embodiment, guide devices 10 are installed at the four corners of the first stacked disc structure 220 and the second stacked disc structure 350. The guide devices 10 not only play a guiding role, but also provide precise trajectory constraints when the first stacked disc structure 220 or the second stacked disc structure 350 moves, ensuring that the stacked disc structure remains stable and accurate during operation, effectively improving the efficiency and safety of the recovery work.

[0038] In a feasible embodiment, the device is provided with a detection module, which is installed on the loading unit 110 and the unloading unit 140, and is used to detect the position of the first stacking disc structure 220 and the second stacking disc structure 350 in real time, ensuring the accuracy and stability during operation, and further improving the overall operating efficiency and safety of the device. It should be pointed out that the detection module can be an image sensor module, which can detect the height of the first stacking disc structure 220 and the second stacking disc structure 350 in real time, ensuring that the loading tray or empty loading tray on the stacking disc does not exceed the preset safety height during the stacking process, and preventing the loading tray from overturning due to the stacking disc being too high. Once the stacking disc height reaches or exceeds the preset safety threshold, the image sensor module will immediately issue a warning signal to enable the device control system to automatically stop feeding or take other emergency measures to ensure the safety of the equipment and the loading tray.

[0039] In a feasible embodiment, the detection module can also monitor the position status of the first jacking structure 210 and the second jacking structure 340 in real time to ensure that the jacking structures can accurately stop at the set positions when working.

[0040] In a possible embodiment, if Figure 4 As shown, the circuit unit testing device 410 provided by the present invention can be combined in multiple ways, for example, by stacking multiple layers, to achieve simultaneous testing, thereby significantly improving the testing efficiency.

[0041] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
