Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment testing, and in particular to automatic testing equipment for PCBA board components and an application method thereof. Background Art

[0002] In the electronics manufacturing industry, quality control of printed circuit board assemblies (PCBAs) is critical. As electronic products rapidly develop toward miniaturization, multifunctionality, and high reliability, the number of components on PCBA boards continues to increase, the density is increasing, the pin pitch is getting smaller, and the complexity of its design and manufacturing has also increased significantly.

[0003] Traditional PCBA board testing mainly relies on manual operation of test instruments. This method has many disadvantages, which seriously affects the test efficiency and accuracy. First of all, manual testing requires testers to frequently connect and disassemble test probes and components on the PCBA board, which is cumbersome and time-consuming. For example, for a medium-complexity PCBA board, it may contain hundreds of components. Testers need to locate the components one by one, connect probes and record test data. This process may take hours or even longer, which is far from meeting the rapid turnover requirements of modern mass production.

[0004] Furthermore, as the speed of electronic product replacement continues to accelerate, the R&D cycle of new products is getting shorter and shorter, and traditional manual testing methods are difficult to quickly adapt to frequent product changes. Whenever the design of the PCBA board changes, testers need to re-familiarize themselves with the test process and standards and adjust the parameter settings of the test equipment, which undoubtedly further prolongs the time to market for the product and weakens the company's advantage in market competition.

[0005] In addition, the labor cost of manual testing is high. In today's increasingly tight labor market, companies need to invest a lot of human resources in PCBA board testing, which not only increases the company's direct labor costs, but also increases indirect costs such as training costs and management costs. Moreover, the low efficiency of manual testing limits the expansion of the company's production scale and is not conducive to the long-term development of the company.

[0006] In summary, in order to overcome the problems of low efficiency, poor accuracy, weak adaptability and high cost in the traditional manual testing methods in PCBA board component testing, it is urgent to develop a PCBA board component automatic testing equipment and its application method to achieve efficient, accurate and flexible automated testing, improve the production efficiency and product quality of electronic manufacturing enterprises, and enhance the competitiveness of enterprises in the market. Summary of the invention

[0007] In order to improve the detection efficiency of PCBA board components, the present application provides a PCBA board component automatic testing device and an application method thereof.

[0008] The PCBA board component automatic testing equipment and its application method provided in this application adopt the following technical solutions: The invention discloses an automatic testing device for components of a PCBA board and an application method thereof, comprising a frame, a control system being arranged on one side of the frame, a test platform being arranged on the frame, and a positioning block for positioning the PCBA board being arranged on the test platform, an electrical test module electrically connected to the control system being lifted and lowered above the test platform, a detection assembly cooperating with components of the PCBA board being arranged at the bottom of the electrical test module, and a connector being arranged between the electrical test module and the detection assembly, the detection assembly comprising a detection frame and a plurality of probes arranged on the detection frame according to the positions of the components, a guide rod being arranged for docking between the detection frame and the test platform, and the top ends of the plurality of probes being arranged through and extending to the top wall of the detection frame and the bottom ends being arranged through and extending to the bottom wall of the detection frame.

[0009] By adopting the above technical solution, the equipment ensures that each PCBA board can be accurately positioned and fixed through the control system on the rack and the positioning block on the test platform, thereby avoiding test errors caused by position deviation; and can flexibly configure the fixing plate and the detection component according to different types of PCBA boards, and use the connector to achieve accurate and rapid installation between the detection component and the electrical test module, so that the detection component can accurately contact the components on the PCBA board, improving the reliability and consistency of the test; the probe layout on the detection frame is customized according to the position of the components, ensuring that each component can be effectively tested, further improving the comprehensiveness and accuracy of the test; in addition, the design of the guide rod ensures that the detection component remains stable during the up and down movement, reducing the impact of mechanical vibration on the test results. Therefore, the equipment significantly improves the efficiency and accuracy of PCBA board component testing and reduces the uncertainty and error rate caused by human factors.

[0010] Optionally, a fixing plate is provided on the test platform, and an avoidance groove is provided on the fixing plate to protect the protruding part of the bottom of the PCBA board. A plurality of guide pillars vertically plugged into the test platform are arranged at the bottom of the fixing plate. The guide pillars are arranged to avoid the avoidance groove, and each of the guide pillars is provided with an elastic member that abuts between the fixing plate and the test platform.

[0011] By adopting the above technical solution, the avoidance groove on the fixed plate can effectively accommodate the components at the bottom of the PCBA board, avoiding interference between the components and the test platform during the test, and improving the stability and reliability of the test. The combined design of the guide column and the elastic member allows the fixed plate to float freely in the vertical direction, thereby ensuring that the PCBA board is subjected to uniform pressure during the test, enhancing the accuracy and consistency of the test. At the same time, the elastic member can also absorb the vibration generated during the test, reducing the impact on the test results.

[0012] Optionally, the positioning block is arranged on a fixed plate, and a plurality of the positioning blocks are provided. When the PCBA board is placed on the fixed plate, the plurality of positioning blocks surround the PCBA board and fit with the side wall of the PCBA board, and each of the positioning blocks is provided with a chamfer toward the top wall of the PCBA board.

[0013] By adopting the above technical solution, multiple positioning blocks can effectively fix the position of the PCBA board, ensuring that the PCBA board will not shift during the test, thereby improving the stability and accuracy of the test. The chamfer design makes it easier for the positioning blocks to guide the PCBA board into the predetermined position, reducing the test error caused by improper alignment.

[0014] Optionally, the positioning block is slidably arranged on a fixed plate in the direction of the PCBA board, and a support plate is arranged on the side of each positioning block facing away from the PCBA board, the support plate is fixedly arranged on the fixed plate, and a plurality of guide rods are distributed along the length direction of the positioning block toward the side wall of the support plate, and the length direction of the plurality of guide rods is parallel to the sliding direction of the positioning block, and the end of each guide rod is slidably passed through the corresponding support plate, and a plug that contacts the side wall of the support plate is arranged on the end of the guide rod passing through the support plate, and a magnetic block that repel magnets is arranged on the side wall of the support plate opposite to the positioning block.

[0015] By adopting the above technical solution, the structure can effectively ensure the stability and accuracy of the PCBA board during the test process. Specifically, the sliding setting of the positioning block and the magnetically repelling magnetic block enable the positioning block to adjust its position adaptively, thereby better providing a suitable clamping force for the PCBA board. At the same time, the design of the guide rod and the plug ensures that the positioning block will not deviate during the sliding process, thereby improving the positioning accuracy of the PCBA board. Therefore, the error caused by improper manual operation is reduced, and the reliability and repeatability of the test are improved.

[0016] Optionally, a chassis is provided on the top of the frame, a driving cylinder is vertically arranged in the chassis, and the piston rod of the driving cylinder slides through the bottom wall of the chassis, and the end of the piston rod extending out of the chassis is connected to a horizontally arranged connecting plate, the electrical test module is bolted to the bottom of the connecting plate, and the top of the connecting plate is provided with columns on both sides of the driving cylinder piston rod, the top of the column slides through the bottom wall of the chassis and extends into the chassis, and the length of the column exceeds the telescopic range of the driving cylinder piston rod.

[0017] By adopting the above technical solution, under the effective guidance of the column, the driving cylinder can accurately control the lifting and lowering action of the electrical test module, ensuring that the detection component can smoothly and accurately contact the components on the PCBA board, thereby improving the reliability and repeatability of the test.

[0018] Optionally, the connecting member includes a double-rod cylinder arranged on the top of the connecting plate and a fixed clamp block connected to the end of the piston rod of the double-rod cylinder, the fixed clamp block is arranged in a U-shape, and the openings of the fixed clamp block on the two piston rod ends of the double-rod cylinder are arranged opposite to each other, and the side walls on the same side of the electrical test module and the detection frame are jointly limited in the fixed clamp block.

[0019] By adopting the above technical solution, during the installation of the detection assembly, first, the guide rods on the detection frame are inserted and placed in the corresponding holes on the test platform, and the detection frame is now placed stably on the test platform; then the electrical test module is driven down until the detection frame fits the electrical test module; finally, the piston rods at both ends of the double-rod cylinder are driven back until the fixed clamps clamp the side walls on the same side of the electrical test module and the detection frame to limit the position, thereby achieving synchronous movement between the electrical test module and the detection frame. The use of the double-rod cylinder allows the electrical test module and the detection frame to be connected accurately and quickly. This connection method can ensure the stability and accuracy between the electrical test module and the detection frame, improve the efficiency and consistency of the test, and thus avoid test errors caused by vibration or movement during the test process.

[0020] Optionally, a calibration hole is provided on the PCBA board, and a calibration rod which slides through the calibration hole is provided on the bottom wall of the detection frame.

[0021] By adopting the above technical solution, the setting of the verification hole and the verification rod can effectively detect the placement direction of the PCBA board, ensure the correct alignment of the PCBA board during the test process, avoid test failure or misjudgment caused by placement error, thereby improving the accuracy and reliability of the test.

[0022] Optionally, a piezoelectric ceramic sheet is disposed on the top of each positioning block, and the piezoelectric ceramic sheet is electrically connected to a control system.

[0023] By adopting the above technical solution, the piezoelectric ceramic sheet can monitor the pressure changes between the probe and the PCBA board components in real time, and convert the pressure changes into electrical signals and transmit them to the control system. The control system can adjust the descent speed or contact pressure of the detection component in real time according to these electrical signals to ensure the contact stability and accuracy between the probe and the components during the test, avoid damage to the components due to excessive pressure, and ensure the reliability and repeatability of the test results.

[0024] The application method of the PCBA board component automatic testing equipment comprises the following steps: S1. Before testing, select and install the corresponding fixing plate and detection assembly according to the type of PCBA board to be tested; S2. The PCBA board to be tested is plugged and placed on the fixing plate. Under the action of magnetic repulsion, multiple positioning blocks jointly fix the PCBA board; S3, observe whether the calibration rod corresponds to the calibration hole, and then start the control system to make the electrical test module drive the detection component to descend to contact the PCBA board; S4, the probe of the detection assembly contacts the components on the top of the PCBA board, and the detection frame contacts the piezoelectric ceramic sheet. Under the support of the elastic member and the fixing plate, the detection assembly continues to press down until the components on the bottom of the PCBA board contact the probe on the test platform, and then the electrical test is performed; S5. After the test is completed, the control system drives the detection component to rise and remove the PCBA board; S6. Record and analyze the test results.

[0025] By adopting the above technical solution, the method replaces the traditional manual test with automated equipment, reduces the uncertainty and error of manual operation, and improves the consistency and repeatability of the test. At the same time, the replaceable design of the fixing plate and the detection component enables the equipment to quickly adapt to PCBA boards of different types and specifications, greatly shortening the test preparation time and product launch cycle. In addition, the magnetic repulsive positioning block design ensures the stable fixation of the PCBA board and avoids test failures caused by movement. The use of the calibration rod further ensures the correct placement direction of the PCBA board and improves the reliability and safety of the test. Finally, by real-time monitoring and adjustment of the descending speed and contact pressure of the detection component, precise control of the test process is achieved, ensuring the accuracy and stability of the test results.

[0026] Optionally, when the probe contacts the PCBA board components for testing, the pressure will be transmitted to the piezoelectric ceramic sheet, causing the piezoelectric ceramic sheet to generate electric charge. The charge gathers to form a feedback signal that is transmitted to the control system. The control system can adjust the descent speed or contact pressure of the detection component in real time based on this feedback signal.

[0027] By adopting the above technical solution, the contact pressure during the PCBA board component testing process can be accurately controlled to avoid component damage due to excessive pressure or inaccurate testing due to insufficient pressure, thereby significantly improving the reliability and accuracy of the test. At the same time, this real-time adjustment function can also effectively reduce the test time and improve the test efficiency.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. Significantly improve test efficiency: Through automated equipment, rapid positioning and testing of PCBA board components are achieved, overcoming the problems of low efficiency, poor accuracy, weak adaptability and high cost in manual testing methods in PCBA board component testing. Especially when dealing with highly complex PCBA boards, the test time is greatly shortened; 2. Improve test accuracy: Use precise positioning blocks and detection components to ensure accurate contact between the probe and PCBA board components, avoid test errors caused by human factors, and improve the reliability and consistency of test results; 3. Quickly adapt to different PCBA board designs: By replacing different fixing plates and detection components, different types of PCBA boards can be quickly responded to without readjusting the test process and standards, which greatly shortens the time to market for new products and enhances the company's market competitiveness.
