Description

Technical Field

[0001] This utility model relates to the field of circuit board testing technology, and specifically to a domain controller circuit board testing device. Background Technology

[0002] In today's era of rapid technological advancement, the electronics manufacturing industry, as a crucial pillar of the global economy, is experiencing vigorous growth. From consumer electronics devices such as smartphones and tablets to high-end fields like industrial automation and aerospace, market demand for various electronic products continues to grow. Circuit boards, as core components of electronic products, directly determine the overall quality and stability of these products. As consumers demand increasingly higher levels of functionality, performance, and reliability from electronic products, electronics manufacturers face immense pressure to improve product quality, shorten production cycles, and reduce production costs.

[0003] Currently, there are some automatic testing equipment for circuit boards on the market, but the degree of automation of some equipment is not high enough. During the loading, unloading and testing of circuit boards, a lot of manual intervention is still required, which fails to achieve truly fully automated production. The testing efficiency is low, and the equipment has problems such as single function and poor compatibility. Some equipment cannot adapt to the testing needs of circuit boards of different specifications and functions. Utility Model Content

[0004] The purpose of this invention is to provide a domain controller circuit board testing device that is highly automated, improves testing efficiency and reliability, and has good compatibility and scalability.

[0005] A domain controller circuit board testing device includes a lower frame with several panels mounted on it. The panels are characterized by housing a robot device, several sets of tooling testing devices, an NG tray assembly, and a tray transfer device. The lower frame contains several sets of testing instruments, a blister pack hopper, and two parallel blister pack lifting devices installed within the blister pack hopper. The tray transfer device is located above the blister pack hopper. The robot device is used to transport the circuit board. The tooling testing devices are used to quickly fix and test the circuit board. The testing instruments are electrically connected to the tooling testing devices via cables. The tooling testing device includes a mounting base plate, a tooling testing interlocking mechanism, and a tooling positioning mechanism. The mounting base plate is mounted on the panel, and the tooling testing interlocking mechanism and the tooling positioning mechanism are mounted on the mounting base plate. The tooling positioning mechanism is used to position and fix the circuit board, and the tooling testing interlocking mechanism is used to test the interface of the circuit board.

[0006] In the above scheme, a robotic device transports the circuit board to be tested onto the tooling testing device. The tooling positioning mechanism can accurately position and fix the circuit board, ensuring its stable position throughout the testing process. This allows the tooling testing interlocking mechanism to accurately connect to the circuit board's interface, guaranteeing accurate transmission of test signals and improving the accuracy and reliability of the test results. The testing instrument sends various test commands to the tooling testing device via cables. The tooling testing device performs a series of basic functional tests on the circuit board according to these commands, such as detecting circuit continuity, voltage, and current parameters. It also feeds back the electrical signals generated during the testing process to the testing instrument in real time. The testing instrument then evaluates the circuit board against preset pass / fail standards. The overall performance of the circuit board is evaluated, and the test results are obtained to determine whether the circuit board is qualified. Qualified circuit boards are placed in the blister box at the blister box lifting device position, and unqualified circuit boards are placed in the blister box at the NG tray assembly position. Two sets of blister box lifting devices respectively carry empty blister boxes and blister boxes filled with circuit boards. The blister box lifting devices, blister box hoppers and tray transfer devices work together to realize the automatic unloading of circuit boards. The entire testing process is highly automated. From the loading of circuit boards, testing to unloading and classification, each link is closely connected without frequent manual intervention. The rapid handling of the robotic device and the efficient testing of the tooling testing device greatly shorten the testing time of a single circuit board and increase the testing output per unit time.

[0007] Furthermore, the tooling testing device includes a mounting base plate, a tooling testing mating mechanism, and a tooling positioning mechanism. The mounting base plate is mounted on the panel, and the tooling testing mating mechanism and the tooling positioning mechanism are mounted on the mounting base plate. The tooling positioning mechanism is used to position and fix the circuit board, and the tooling testing mating mechanism is used to test the interface of the circuit board.

[0008] In the above scheme, the tooling positioning mechanism can accurately position and fix the circuit board. During the test, the circuit board always maintains a stable position, so that the tooling test mating mechanism can accurately plug into the interface of the circuit board, ensuring the accurate transmission of test signals, thereby improving the accuracy and reliability of test results. The coordinated work of the tooling positioning mechanism and the tooling test mating mechanism realizes the rapid positioning, fixing and test connection of the circuit board. With the cooperation of the robot device, the loading, testing and unloading process of the circuit board can be completed quickly, which can shorten the testing time of a single circuit board and thus increase the test output per unit time.

[0009] Furthermore, the tooling test mating mechanism includes a first support component, a push cylinder, a connecting component, and several probe components. The first support component is mounted on the mounting base plate, the push cylinder is mounted on the first support component, the connecting component is connected to the push cylinder, and several probe components are mounted horizontally on the connecting component.

[0010] In the above scheme, the push cylinder provides stable and controllable power for the movement of the probe assembly. By precisely controlling the stroke and thrust of the push cylinder, it can be ensured that the probe assembly can be accurately and smoothly inserted into the interface of the circuit board, avoiding problems such as poor contact caused by uneven insertion force or inaccurate insertion position. The coordinated work of the tooling test insertion mechanism with other components such as the robot device and tooling positioning mechanism realizes the automation and continuity of the circuit board testing process. The close connection of each link reduces manual intervention and operation time, thereby improving testing efficiency and reliability.

[0011] Furthermore, the tooling positioning mechanism includes a second support component, a positioning component, and a lateral clamping component. The positioning component includes a placement plate, a limiting block, and a positioning block. The placement plate is mounted on the second support component. The limiting block is located on one side of the placement plate. The two positioning blocks are arranged adjacent to the two ends of the other side of the placement plate. The positioning blocks are elastically slidably connected to the second support component. The lateral clamping component is used to limit the lateral displacement of the circuit board.

[0012] In the above scheme, the limiting block and the positioning block can restrict the vertical position of the circuit board. The elastic sliding characteristic of the positioning block allows it to adaptively adjust according to the actual size and placement position of the circuit board, ensuring that the circuit board can be accurately placed in the predetermined test position. The lateral clamping component applies a force from the lateral direction of the circuit board, restricting the displacement of the circuit board in the lateral direction. The positioning component and the lateral clamping component work together to keep the circuit board stable during the test, avoiding positional movement due to external forces or vibrations during the test, ensuring that the interface of the circuit board can accurately mate with the probe component of the tooling test mating mechanism, and ensuring the reliability of the test.

[0013] Furthermore, the lateral clamping assembly includes a telescopic cylinder, a connecting block, and a clamping block. The connecting block is connected to the telescopic cylinder, and the clamping block is connected to the connecting block. The support base plate on the second support assembly has a slot corresponding to the position of the connecting block.

[0014] In the above solution, the telescopic cylinder can precisely control the extension and retraction length of the piston rod, thereby precisely controlling the moving distance of the clamping block and the applied clamping force. This allows the clamping block to accurately contact the circuit board and apply appropriate clamping force according to the actual needs of the circuit board. This ensures that the circuit board will not undergo lateral displacement during testing, nor will it be damaged due to excessive clamping force. The slot on the support base plate cleverly utilizes the existing structural space, enabling the clamping block to effectively contact the circuit board within a limited space without increasing the overall volume of the device.

[0015] Furthermore, the robot device includes a transport robot and a material handling mechanism. The material handling mechanism includes a connecting frame and a connecting base plate. The connecting frame is connected to the execution end of the transport robot, and the connecting base plate is connected to the connecting frame. Multiple first vacuum suction cups are movably mounted on the connecting base plate.

[0016] In the above scheme, the connecting frame of the picking and placing mechanism is connected to the execution end of the handling robot and moves synchronously with the movement of the handling robot. The connecting base plate is installed on the connecting frame and will also reach the corresponding position. The handling robot has high-precision motion control capability and can quickly and accurately carry out the handling of the circuit board according to the preset precise path. The first vacuum suction cup can be adjusted to be installed on the connecting base plate according to the structure of the circuit board to ensure that the circuit board is stably adsorbed.

[0017] Furthermore, a CCD device is also provided in the lower frame. The CCD device is electrically connected to the tooling testing device. The CCD device includes several sets of CCD components, a support frame, and a display. The CCD components are installed at one end of the support frame, and the display is located at the other end of the support frame.

[0018] In the above scheme, the CCD device can work with the testing instrument to test the display function of the circuit board. The high-resolution imaging of the CCD device and the precise comparison and analysis capabilities of the testing instrument can detect extremely small defects on the display screen, thereby accurately determining whether the display function of the circuit board is normal. This high-precision testing can effectively screen out circuit boards with quality problems, prevent defective products from entering the market, and improve the overall quality and reliability of the products.

[0019] Furthermore, the blister box hopper includes a first accommodating space and a second accommodating space. The bottom of both the first accommodating space and the second accommodating space is provided with a conveying mechanism. The conveying mechanism includes a rotary drive component, a transmission assembly, a first synchronous pulley assembly, and a second synchronous pulley assembly. The rotary drive component is connected to the transmission assembly. The transmission assembly is used to connect the first synchronous pulley assembly and the rotary drive component. The first synchronous pulley assembly is connected to the second synchronous pulley assembly through a transmission rod.

[0020] In the above scheme, the transmission component receives the power output from the rotary drive component and transmits it to the first synchronous pulley assembly. The transmission component can be a belt, chain, or gear transmission method. The first synchronous pulley assembly begins to rotate after receiving the power from the transmission component. Since the first synchronous pulley assembly is connected to the second synchronous pulley assembly via a transmission rod, the rotation of the first synchronous pulley assembly drives the transmission rod to rotate, which in turn causes the second synchronous pulley assembly to rotate as well. The first and second synchronous pulley assemblies operate synchronously, providing power for the conveying of the blister pack.

[0021] Furthermore, the two sets of blister box lifting devices are respectively located in the first accommodating space and the second accommodating space. The blister box lifting device includes a linear motor module and a lifting plate. The lifting plate is connected to the linear motor module. The panel is provided with a connecting port above the lifting plate. The lifting plate can drive the blister box through the connecting port.

[0022] In the above scheme, the blister box is placed on the lifting plate. The lifting plate is driven to rise and fall by a linear motor module, thereby driving the blister box to rise and fall. The connection port allows the blister box to rise and fall freely on the panel. The blister box lifting device in the first accommodating space is used to drive the lifting of empty blister boxes, and the blister box lifting device in the second accommodating space is used to drive the lifting of blister boxes filled with circuit boards. When the top blister box on the lifting plate in the second accommodating space is filled with circuit boards, the linear motor module drives the lifting plate to fall by the height of one blister box. Then, the tray transfer device moves the empty blister box to the blister box filled with circuit boards, and the lifting plate in the second accommodating space rises by the height of one blister box to facilitate the next transfer.

[0023] Furthermore, the testing instrument device includes a mounting bracket, a power supply assembly, a multimeter, an Ethernet converter assembly, and an industrial control computer, all of which are mounted on the mounting bracket.

[0024] In the above scheme, the testing instrument has multiple functions such as data acquisition, transmission, analysis and processing. The power supply component provides stable power support for the multimeter, Ethernet converter component and industrial control computer. The multimeter can measure various electrical parameters, the Ethernet converter component ensures efficient data transmission, and the industrial control computer can perform in-depth analysis and processing of data. Through the collaborative work of these components, the test object can be tested and evaluated comprehensively and accurately, meeting different types of testing needs. The power supply component, multimeter, Ethernet converter component and industrial control computer are integrated and installed on the mounting rack, realizing the integrated design of the testing instrument. This integrated design makes the whole device compact, occupies little space, and is easy to install and transport. At the same time, the connection between the various components is tighter, reducing external interference and improving the stability and reliability of the device.

[0025] Furthermore, the material tray transfer device includes a transverse motor module, a transfer connecting frame, a horizontal plate, and two connecting plates. The transfer connecting frame is connected to the transverse motor module, and a lifting drive component is installed at the end of the transfer connecting frame. The horizontal plate is connected to the lifting drive component, and the two connecting plates are respectively installed at both ends of the horizontal plate. Several second vacuum suction cups are installed on the connecting plates.

[0026] In the above solution, the horizontal moving motor module drives the transfer connecting frame to move horizontally, thereby driving the horizontal plate and connecting plate to move horizontally. The lifting drive can drive the horizontal plate and connecting plate to move back and forth in the vertical direction, thereby ensuring that the second vacuum suction cup can stably and accurately transport the blister tray.

[0027] This utility model provides a domain controller circuit board testing device with the advantages of high automation, improved testing efficiency and reliability, good compatibility and scalability. The circuit board to be tested is transported to the tooling testing device by a robotic device. The tooling positioning mechanism can accurately position and fix the circuit board. During the testing process, the circuit board maintains a stable position, allowing the tooling testing interlocking mechanism to accurately plug into the interface of the circuit board, ensuring accurate transmission of test signals, thereby improving the accuracy and reliability of the test results. The testing instrument sends various test commands to the tooling testing device via cables. The tooling testing device performs a series of basic functional tests on the circuit board according to the commands, such as detecting parameters like circuit continuity, voltage, and current, and feeds back the electrical signals generated during the test to the testing instrument in real time. The testing instrument evaluates the overall performance of the circuit board according to preset pass / fail standards, and finally obtains the test results to determine whether the circuit board is qualified. Qualified circuit boards are placed in the blister box at the blister box lifting device position, and unqualified circuit boards are placed in the blister box at the NG material tray assembly position. Two sets of blister box lifting devices respectively carry empty blister boxes and blister boxes full of circuit boards. The blister box lifting devices, blister box hoppers, and material tray transfer devices work together to realize the automatic unloading of circuit boards. Attached Figure Description

[0040] The present invention provides a domain controller circuit board testing device in further detail below with reference to specific embodiments and accompanying drawings.

[0041] like Figure 1 and Figure 2As shown in a preferred embodiment, a domain controller circuit board testing device of the present invention includes a lower frame 1, on which several panels 2 are mounted. On the panels 2 are mounted a robot device 3, several sets of tooling testing devices 4, an NG tray assembly 5, and a tray transfer device 6. The lower frame 1 contains several sets of CCD devices 7, several sets of testing instrument devices 8, a blister pack hopper 9, and two parallel blister pack lifting devices 10 installed within the blister pack hopper 9. The tray transfer device 6 is located above the blister pack hopper 9. The robot device 3 is used to transport the circuit board. The tooling testing devices 4 are used to quickly fix and test the circuit board. The testing instrument devices 8 are electrically connected to the tooling testing devices 4 via cables.

[0042] In this embodiment, the circuit board to be tested is transported to the tooling testing device 4 by the robot device 3. The tooling testing device 4 can quickly fix the circuit board for testing. The testing instrument device 8 sends various test commands to the tooling testing device 4 through cables. The tooling testing device 4 performs a series of basic functional tests on the circuit board according to the commands, such as the detection of parameters such as circuit continuity, voltage, and current, and feeds back the electrical signals generated during the test to the testing instrument device 8 in real time. The testing instrument device 8 evaluates the overall performance of the circuit board according to the preset pass criteria and finally obtains the test results to determine whether the circuit board is qualified. Qualified circuit boards are placed in the blister box at the position of the blister box lifting device 10, and unqualified circuit boards are placed in the blister box at the position of the NG material tray assembly 5. The two sets of blister box lifting devices 10 respectively carry empty blister boxes and blister boxes full of circuit boards. The blister box lifting device 10, the blister box hopper 9, and the material tray transfer device 6 work together to realize the automatic unloading of circuit boards.

[0043] The entire testing process is highly automated. From the loading and testing of circuit boards to the unloading and sorting, each step is closely connected without frequent human intervention. The rapid handling by the robot device 3 and the efficient testing by the tooling testing device 4 greatly shorten the testing time for a single circuit board and increase the testing output per unit time. The equipment is equipped with several sets of tooling testing devices 4 and CCD devices 7, which can test multiple circuit boards simultaneously, improving the overall testing efficiency and meeting the needs of large-scale production. Multiple sets of tooling testing devices 4 are equipped with independent testing instrument devices 8 and CCD devices 7, which can be customized and adjusted according to specific product specifications.

[0044] like Figures 3 to 5As shown, in some embodiments, the tooling testing device 4 includes a mounting base plate 41, a tooling testing mating mechanism 43, and a tooling positioning mechanism 42. The mounting base plate 41 is mounted on the panel 2, and the tooling testing mating mechanism 43 and the tooling positioning mechanism 42 are mounted on the mounting base plate 41. The tooling positioning mechanism 42 is used to position and fix the circuit board, and the tooling testing mating mechanism 43 is used to test the interface of the circuit board. The robot device 3 transports the circuit board to be tested onto the mounting base plate 41 of the tooling testing device 4. The tooling positioning mechanism 42 starts working, accurately positioning the circuit board at the designated position on the mounting base plate 41 using a preset positioning method, and firmly fixing the circuit board to ensure that it will not shift during subsequent testing, thus ensuring the accuracy and stability of the test.

[0045] The tooling positioning mechanism 42 can accurately position and fix the circuit board. During the test, the circuit board always maintains a stable position, allowing the tooling test mating mechanism 43 to accurately plug into the interface of the circuit board, ensuring accurate transmission of test signals, thereby improving the accuracy and reliability of the test results. The tooling test mating mechanism 43 transmits these test instructions to the circuit board, and at the same time receives the electrical signals fed back from the circuit board, and transmits these signals back to the test instrument device 8. The test instrument device 8 evaluates the various functions of the circuit board based on the received signals and in conjunction with the preset pass standards, and determines whether it is qualified. The coordinated work of the tooling positioning mechanism 42 and the tooling test mating mechanism 43 realizes the rapid positioning, fixing and test connection of the circuit board. With the cooperation of the robot device 3, the loading, testing and unloading process of the circuit board can be completed quickly, which can shorten the testing time of a single circuit board, thereby increasing the test output per unit time.

[0046] like Figures 3 to 5 As shown, in some embodiments, the tooling test mating mechanism 43 includes a first support component 431, a push cylinder 432, a connecting component 433, and several probe components 434. The first support component 431 is mounted on the mounting base plate 41, the push cylinder 432 is mounted on the first support component 431, the connecting component 433 is connected to the push cylinder 432, and the several probe components 434 are horizontally mounted on the connecting component 433. The push cylinder 432 provides stable and controllable power for the movement of the probe components 434. By precisely controlling the stroke and thrust of the push cylinder 432, it can be ensured that the probe components 434 can be accurately and smoothly inserted into the interface of the circuit board, avoiding problems such as poor contact caused by uneven insertion force or inaccurate insertion position. The tooling test mating mechanism 43, together with the robot device 3, the tooling positioning mechanism 42, and other components, realizes the automation and continuity of the circuit board testing process. The close connection of each link reduces manual intervention and operation time, thereby improving testing efficiency and reliability.

[0047] like Figures 3 to 5 As shown, in some embodiments, the tooling positioning mechanism 42 includes a second support component 421, a positioning component 422, and a lateral clamping component 423. The positioning component 422 includes a placement plate 4221, a limiting block 4222, and a positioning block 4223. The placement plate 4221 is mounted on the second support component 421. The limiting block 4222 is disposed on one side of the placement plate 4221. The two positioning blocks 4223 are disposed adjacent to the two ends on the other side of the placement plate 4221. The positioning blocks 4223 are elastically slidably connected to the second support component 421. The lateral clamping component 423 is used to limit the lateral displacement of the circuit board. Limiting block 4222 and positioning block 4223 can limit the vertical position of the circuit board. The elastic sliding characteristic of positioning block 4223 allows it to adaptively adjust according to the actual size and placement position of the circuit board, ensuring that the circuit board can be accurately placed in the predetermined test position. Lateral clamping component 423 applies force from the lateral direction of the circuit board, limiting the displacement of the circuit board in the lateral direction. The positioning component 422 and the lateral clamping component 423 cooperate to keep the circuit board stable during the test, avoiding positional movement due to external forces or vibrations during the test, ensuring that the interface of the circuit board can accurately dock with the probe component 434 of the tooling test mating mechanism 43, and ensuring the reliability of the test.

[0048] like Figures 3 to 5 As shown, in some embodiments, the lateral clamping assembly 423 includes a telescopic cylinder 4231, a connecting block 4232, and a clamping block 4233. The connecting block 4232 is connected to the telescopic cylinder 4231, and the clamping block 4233 is connected to the connecting block 4232. The support base plate 4211 on the second support assembly 421 has a slot 4212 corresponding to the position of the connecting block 4232. The telescopic cylinder 4231 can precisely control the extension and retraction length of the piston rod, thereby precisely controlling the moving distance and applied clamping force of the clamping block 4233. This allows the clamping block 4233 to accurately abut against the circuit board and apply an appropriate clamping force according to the actual needs of the circuit board. This ensures that the circuit board will not undergo lateral displacement during testing, and will not be damaged due to excessive clamping force. The slot 4212 on the support base plate 4211 cleverly utilizes the existing structural space, enabling the clamping block 4233 to effectively abut against the circuit board within a limited space without increasing the overall volume of the device.

[0049] like Figure 6As shown, in some embodiments, the robot device 3 includes a handling robot 31 and a picking and placing mechanism 32. The picking and placing mechanism 32 includes a connecting frame 321 and a connecting base plate 322. The connecting frame 321 is connected to the execution end of the handling robot 31, and the connecting base plate 322 is connected to the connecting frame 321. Multiple first vacuum suction cups 323 are movably mounted on the connecting base plate 322. The connecting frame 321 of the picking and placing mechanism 32 is connected to the execution end of the handling robot 31 and moves synchronously with the movement of the handling robot 31. The connecting base plate 322 is mounted on the connecting frame 321 and will also reach the corresponding position. The handling robot 31 has high-precision motion control capabilities and can quickly and accurately transport the circuit board according to a preset precise path. The first vacuum suction cups 323 can be adjusted in position on the connecting base plate 322 according to the structure of the circuit board to ensure stable adsorption of the circuit board.

[0050] Specifically, when a circuit board picking operation is required, the handling robot 31 receives an instruction from the control system and moves the picking and placing mechanism 32 above the circuit board to be picked according to the preset program and path. The connecting frame 321 of the picking and placing mechanism 32 is connected to the execution end of the handling robot 31 and moves synchronously with the movement of the handling robot 31. The connecting base plate 322 is installed on the connecting frame 321 and will also reach the corresponding position. When the picking and placing mechanism 32 reaches the appropriate position above the circuit board, the control system controls the first vacuum suction cup 323 to start working, so that the first vacuum suction cup 323 generates negative pressure and adsorbs the circuit board. Since multiple first vacuum suction cups 323 are movably installed on the connecting base plate 322, they can make certain adaptive adjustments according to the surface shape and position of the circuit board to ensure stable adsorption of the circuit board.

[0051] like Figure 7 As shown, in some embodiments, a CCD device 7 is also provided in the lower frame 1. The CCD device 7 is electrically connected to the tooling testing device 4. The CCD device 7 includes several sets of CCD components 71, a support frame 72, and a display 73. The CCD components 71 are installed at one end of the support frame 72, and the display 73 is located at the other end of the support frame 72. The CCD device 7 can cooperate with the testing instrument device 8 to detect the display function of the circuit board. The high-resolution imaging of the CCD device 7 and the precise comparison and analysis capability of the testing instrument device 8 can detect extremely small defects on the screen of the display 73, thereby accurately determining whether the display function of the circuit board is normal. This high-precision detection can effectively screen out circuit boards with quality problems, prevent defective products from entering the market, and improve the overall quality and reliability of the products.

[0052] In the above embodiment, when the circuit board and the display 73 are connected and the testing phase begins, the CCD device 7 receives a start signal and begins to work. Several sets of CCD components 71 installed at one end of the support frame 72 take high-resolution pictures of the display 73 screen. The charge-coupled devices in the CCD components 71 can convert the light signals emitted by the display 73 screen into electrical signals and then into digital image information. Since there are multiple sets of CCD components 71, the screen can be photographed from different angles or areas to ensure that the entire display 73 screen display information can be captured comprehensively and clearly, including all corners and details of the screen. After the captured image information is converted into electrical signals inside the CCD components 71, it is transmitted to the testing instrument device 8 through a data cable or wireless transmission.

[0053] like Figure 2 and Figure 8 As shown, in some embodiments, the blister pack hopper 9 includes a first accommodating space 91 and a second accommodating space 92. Both the first accommodating space 91 and the bottom of the second accommodating space 92 are provided with a conveying mechanism 93. The conveying mechanism 93 includes a rotary drive component 931, a transmission assembly 932, a first synchronous pulley assembly 933, and a second synchronous pulley assembly 934. The rotary drive component 931 is driveably connected to the transmission assembly 932. The transmission assembly 932 connects the first synchronous pulley assembly 933 and the rotary drive component 931. The first synchronous pulley assembly 933 is connected to the second synchronous pulley assembly 934 via a transmission rod 935. The transmission assembly 932 receives the power output from the rotary drive component 931 and transmits it to the first synchronous pulley assembly. The transmission assembly 932 can be a belt, chain, or gear transmission method. The first synchronous pulley assembly 933 begins to rotate after receiving the power transmitted by the transmission assembly 932. Since the first synchronous pulley assembly 933 is connected to the second synchronous pulley assembly 934 via the transmission rod 935, the rotation of the first synchronous pulley assembly 933 will drive the transmission rod 935 to rotate, thereby causing the second synchronous pulley assembly 934 to rotate as well. The first synchronous pulley assembly 933 and the second synchronous pulley assembly 934 operate synchronously, providing power for the conveying of the blister pack.

[0054] like Figure 2 , Figure 8 and Figure 9As shown, in some embodiments, two sets of blister box lifting devices 10 are respectively located in the first accommodating space 91 and the second accommodating space 92. The blister box lifting device 10 includes a linear motor module 101 and a lifting plate 102. The lifting plate 102 is connected to the linear motor module 101. The panel 2 is provided with a connecting port above the lifting plate 102. The lifting plate 102 can drive the blister box through the connecting port. The blister pack is mounted on the lifting plate 102. The lifting plate 102 is driven to rise and fall by the linear motor module 101, thereby driving the blister pack to rise and fall. The connection port allows the blister pack to rise and fall freely on the panel 2. The blister pack lifting device 10 in the first accommodating space 91 is used to drive the lifting of empty blister packs. The blister pack lifting device 10 in the second accommodating space 92 is used to drive the lifting of blister packs filled with circuit boards. When the uppermost blister pack on the lifting plate 102 in the second accommodating space 92 is filled with circuit boards, the linear motor module 101 drives the lifting plate 102 to fall by the height of one blister pack. Then, the tray transfer device 6 moves the empty blister pack to the blister pack filled with circuit boards. The lifting plate 102 in the second accommodating space 92 rises by the height of one blister pack to facilitate the next transfer.

[0055] In this embodiment, after a certain number of blister packs are stacked on the lifting plate 102 in the second accommodating space 92, the linear motor module 101 drives the lifting plate 102 to descend until the blister packs overlap the first synchronous pulley assembly 933 and the second synchronous pulley assembly 934. The blister packs filled with circuit boards are moved to the unloading position through the transmission assembly 932. When the empty blister packs on the lifting plate 102 in the first accommodating space 91 are used up, the linear motor module 101 drives the lifting plate 102 to descend, and the empty blister packs are transferred from the loading position of the lower frame 1 to the lifting plate 102 through the conveying assembly, thereby realizing the automatic loading and unloading of blister packs and circuit boards.

[0056] like Figure 2 and Figure 10As shown, in some embodiments, the test instrument device 8 includes a mounting bracket 81, a power supply assembly 82, a multimeter 83, an Ethernet converter assembly 84, and an industrial computer 85, all of which are mounted on the mounting bracket 81. The testing instrument device 8 has multiple functions such as data acquisition, transmission, analysis, and processing. The power supply component 82 provides stable power support for the multimeter 83, Ethernet converter component 84, and industrial control computer 85. The multimeter 83 can measure various electrical parameters, the Ethernet converter component 84 ensures efficient data transmission, and the industrial control computer 85 can perform in-depth analysis and processing of data. Through the collaborative work of these components, the test object can be tested and evaluated comprehensively and accurately, meeting different types of testing needs. The power supply component 82, multimeter 83, Ethernet converter component 84, and industrial control computer 85 are integrated and installed on the mounting bracket 81, realizing the integrated design of the testing instrument device 8. This integrated design makes the entire device compact, occupies little space, and is easy to install and transport. At the same time, the connection between the various components is tighter, reducing external interference and improving the stability and reliability of the device.

[0057] like Figure 1 and Figure 11 As shown, in some embodiments, the tray transfer device 6 includes a horizontal transfer motor module 61, a transfer connecting frame 62, a horizontal plate 63, and two connecting plates 64. The transfer connecting frame 62 is connected to the horizontal transfer motor module 61, and a lifting drive component 66 is installed at the end of the transfer connecting frame 62. The horizontal plate 63 is connected to the lifting drive component 66, and the two connecting plates 64 are respectively installed at both ends of the horizontal plate 63. A plurality of second vacuum suction cups 65 are installed on the connecting plates 64. The horizontal transfer motor module 61 drives the transfer connecting frame 62 to move horizontally, thereby driving the horizontal plate 63 and the connecting plates 64 to move horizontally. The lifting drive component 66 can drive the horizontal plate 63 and the connecting plates 64 to move back and forth in the vertical direction, thereby ensuring that the second vacuum suction cups 65 can stably and accurately transport the blister tray.

[0058] The working principle and process of this utility model of a domain controller circuit board testing equipment are as follows: The robot device 3 transports the circuit board to be tested onto the tooling testing device 4. The tooling positioning mechanism 42 starts working, which accurately positions the circuit board at the designated position on the mounting base plate 41 through a preset positioning method and firmly fixes the circuit board. The probe assembly 434 of the tooling test mating mechanism 43 is inserted into the interface of the circuit board. The tooling test mating mechanism 43 transmits test commands to the circuit board and receives the electrical signals fed back from the circuit board, and transmits these signals back to the testing instrument device 8. The testing instrument device 8 evaluates the various functions of the circuit board based on the received signals and combined with the preset pass criteria to determine whether it is qualified. The CCD device 7 can cooperate with the testing instrument device 8 to detect the display function of the circuit board. The robot device transports the unqualified circuit board to the NG material tray assembly 5, and the qualified circuit board to the blister box lifting device 10 of the second accommodating space 92.
