[0002] PCBA (Printed Circuit Board Assembly Module) is a circuit board module formed by mounting electronic components onto a printed circuit board using specific assembly processes, followed by soldering, testing, and other procedures. As a core component of a remote control, the PCBA receives user input via buttons, converts these commands into electrical signals for transmission, and thus enables remote control of the device.
[0003] In the PCBA production process, to ensure its performance and quality, the assembled PCBA board usually needs to undergo functional tests such as power and frequency. Existing PCBA testing mechanisms typically include a conveying component and a testing component. The conveying component includes a suction cup for adsorbing the PCBA board. The suction cup is connected to a loading drive component, which can drive the suction cup to approach the testing component to adsorb the PCBA board to the testing component and perform functional tests.
[0004] However, with the transport components constantly traveling back and forth to deliver different batches of PCBAs to the testing components, the testing process of PCBAs is difficult to maintain continuity, and the testing efficiency of PCBA testing institutions is affected.

The unloading adsorption component and the loading adsorption component can respectively load or unload PCBAs onto the test fixture and the buffer fixture. The buffer component buffers PCBAs during the testing of the test components to ensure continuous testing of different batches of PCBAs, thereby improving testing efficiency.
[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects:
[0007] This utility model provides an automated PCBA testing mechanism, including a frame with a moving path. The frame has a test fixture for testing the PCBA and a buffer fixture for buffering the PCBA, both mounted on the moving path. A testing component tests the PCBA at the test fixture. A buffer component is slidably mounted on the frame along the moving path; during testing, the buffer component adsorbs the PCBA within the buffer fixture. A feeding component includes a discharge adsorption component and a loading adsorption component, the discharge adsorption component corresponding to the test fixture, and the loading adsorption component corresponding to the buffer fixture.
[0008] In some implementations, the test component includes a test box mounted on the rack, with both the test fixture and the buffer fixture mounted on the test box; and a pressing member slidably mounted on the rack along the moving path, wherein during testing, the pressing member presses down on the PCBA inside the test fixture.
[0009] In some implementations, the pressing member includes a test seat slidably disposed on the frame along the movement path; a pressing plate slidably connected to the test seat, the pressing plate being driven by a first lifting drive for driving the pressing plate to move up or down to approach or move away from the test fixture; and a first sliding drive for driving the test seat to approach or move away from the test fixture along the movement path.
[0010] In some implementations, the test box includes a box body and a panel, wherein the test fixture and the buffer fixture are both disposed on the panel, and a mounting base is disposed on the frame, the mounting base being detachably connected to the panel.
[0011] In some implementations, the cache component includes a cache base, which is driven by a second sliding drive member for driving the cache base to move along the movement path; and a cache adsorption member, which is slidably connected to the cache base, and is driven by a second lifting drive member for driving the cache adsorption member to move up and down to approach or move away from the cache fixture.
[0012] In some implementations, the second sliding drive member includes a second drive wheel, a second rotary drive member for driving the second drive wheel to rotate is connected to it; a second driven wheel is disposed on one side of the second drive wheel; and a second transmission belt is sleeved on the outside of the second drive wheel and the second driven wheel, the second drive wheel drives the second driven wheel to rotate via the second transmission belt, and the buffer seat is connected to the second transmission belt.
[0013] In some implementations, multiple buffer fixtures are provided, and the multiple buffer fixtures are arranged on the frame along the moving route; the buffer seats are arranged corresponding to the buffer fixtures, and the multiple buffer seats are connected to the second transmission belt for transmission, and the second transmission belt drives the multiple buffer seats to move synchronously.
[0014] In some implementations, an installation strip is slidably disposed on the buffer seat, the installation strip is connected to the output end of the second lifting drive component, and the buffer adsorption component is detachably connected to the installation strip.
[0015] In some implementations, the mounting strip has an adjustment hole, and the buffer adsorption component is detachably connected to the mounting strip at the adjustment hole to adjust the position of the PCBA.
[0016] In some implementations, the rack is provided with a buffer rail, and the buffer holder is slidably connected to the buffer rail.
[0017] In summary, this utility model has at least the following advantages:
[0018] The PCBA automated testing mechanism provided by this utility model allows for continuous functional testing of PCBAs. The first batch of PCBAs to be tested is placed in the test fixture, while the second batch of PCBAs to be tested is placed in the buffer fixture. Before testing, the buffer component moves along the moving route to the buffer fixture and adsorbs the PCBAs in the buffer fixture. The testing component can then perform functional testing on the PCBAs in the test fixture.
[0019] After the first batch of PCBAs is tested, the unloading suction unit picks up the PCBAs in the test fixture for unloading. At the same time, the loading suction unit picks up the third batch of PCBAs for testing and loads them into the buffer fixture. The unloading operation of the unloading suction unit and the loading operation of the loading suction unit are performed simultaneously. At this time, the second batch of PCBAs buffered at the buffer component is conveyed to the test fixture along the moving route. Subsequently, the buffer component returns to the buffer fixture to pick up the third batch of PCBAs for testing, and the test component can perform the second batch of testing.
[0020] The feeding component enables simultaneous loading and unloading of PCBAs from different test batches, while the buffer component and buffer fixture can buffer the loaded PCBAs. The testing component can perform tests on different batches of PCBAs in an orderly manner, which is conducive to the PCBA automated testing organization to achieve continuous functional testing and ensure testing and production efficiency.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, not all embodiments.
[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0033] Example 1:
[0034] Please see the appendix Figure 1 and Figure 2 The PCBA automated testing mechanism of this invention can realize continuous feeding and testing of workpieces. In particular, it can improve testing and production efficiency when used in functional testing of PCBA5, such as power and frequency testing.
[0035] Please see the appendix Figure 1 The PCBA automated testing mechanism of this utility model includes a frame 1, a moving route 11 is provided on the frame 1, and a test fixture 12 for placing and testing PCBA5 and a buffer fixture 13 for buffering PCBA5 are provided on the moving route 11 on the frame 1. As shown in some specific embodiments, the test fixture 12 and the buffer fixture 13 are arranged side by side.
[0036] A test assembly 2 for testing PCBA5 at test fixture 12 is provided on the frame 1. In a preferred embodiment, the test assembly 2 includes a test box 21, which is mounted on the frame 1. As shown in some specific embodiments, the test box 21 includes a housing 211 and a panel 212. The test fixture 12 and the buffer fixture 13 are both mounted on the panel 212. A fixing seat 14 is provided between the panel 212 and the frame 1. The fixing seat 14 is mounted on the frame 1 and detachably connected to the panel 212. Specifically, the fixing seat 14 and the panel 212 can be assembled with bolts. When different models of PCBA5 need to be tested, the test box 21 can be removed from the fixing seat 14. By replacing the test box 21 with the corresponding model, the PCBA automated testing mechanism can perform functional tests on different models of PCBA5, providing flexible operation. At the same time, compared with traditional testing equipment, the fixing seat 14 fixes the panel 212, which reduces the direct placement of the test fixture 12 on the testing equipment, thereby reducing errors.
[0037] A pressing component 22 is provided on one side of the test box 21. The pressing component 22 is slidably mounted on the frame 1 along the moving path 11. During testing, the pressing component 22 presses the PCBA5 inside the test fixture 12 to perform functional testing.
[0038] A buffer assembly 3 is slidably mounted on the rack 1. The buffer assembly 3 can move closer to or further away from the buffer fixture 13 along the movement path 11 and reciprocate between the buffer fixture 13 and the test fixture 12. The buffer assembly 3 is located on one side of the test piece along the movement direction. When the test assembly 2 performs functional testing on the PCBA5 in the test fixture 12, the buffer assembly 3 can move along the movement path 11 to the buffer fixture 13 and attract the PCBA5 buffered in the buffer fixture 13. After the PCBA5 in the test fixture 12 has completed the test, the attracted buffer PCBA5 is placed back into the test fixture 12 for the next round of functional testing to ensure the continuity of testing.
[0039] Please refer to the appendix. Figure 2A feeding assembly 4 is provided on one side of the frame 1. The feeding assembly 4 includes a discharge adsorption component and a loading adsorption component 41. The discharge adsorption component is correspondingly arranged with the test fixture 12, and the loading adsorption component 41 is correspondingly arranged with the buffer fixture 13. In a preferred embodiment, both the discharge adsorption component and the loading adsorption component 41 can be suction cups to vacuum adsorb the PCBA5.
[0040] As shown in some specific embodiments, the feeding assembly 4 also includes a feeding rack 43, and the unloading adsorption component and the loading adsorption component 41 are slidably disposed on the feeding rack 43. Specifically, the feeding rack 43 can be connected to a robotic arm, which can drive the unloading adsorption component and the loading adsorption component 41 to approach or move away from the frame 1 via the feeding rack 43.
[0041] Furthermore, a feeding drive 411 is provided between the feeding rack 43 and the feeding adsorption component 41. The feeding drive 411 is mounted on the feeding rack 43. Specifically, the feeding drive 411 is preferably, but not limited to, a feeding cylinder. The output end of the feeding drive 411 is connected to a feeding slide 412. The feeding adsorption component 41 is mounted on the feeding slide 412. Specifically, the feeding slide 412 can be slidably connected to the outer shell of the feeding drive 411 to guide the lifting and lowering movements of the feeding slide 412 and the feeding adsorption component 41. During the feeding process, the feeding drive 411 drives the feeding adsorption component 41 to descend via the feeding slide 412, so that the feeding adsorption component 41 approaches the buffer fixture 13. The feeding adsorption component 41 releases the PCBA5, and the PCBA5 falls into the buffer fixture 13 for feeding.
[0042] A feeding drive 421 is provided between the feeding rack 43 and the feeding adsorption component. The feeding drive 421 is mounted on the feeding rack 43. Specifically, the feeding drive 421 is preferably, but not limited to, a feeding cylinder. The output end of the feeding drive 421 is connected to a feeding slide 422. The feeding adsorption component is mounted on the feeding slide 422. Specifically, the feeding slide 422 can be slidably connected to the outer shell of the feeding drive 421 to guide the lifting and lowering movement of the feeding slide 422 and the feeding adsorption component. During the feeding process, the feeding drive 421 drives the feeding adsorption component to descend via the feeding slide 422, so that the feeding adsorption component approaches the test fixture 12. The feeding adsorption component adsorbs the PCBA5, and the PCBA5 leaves the test fixture 12 to be fed. Understandably, when the PCBA automated testing organization is working for the first time, the loading and unloading suction components 41 and 41 can perform loading operations simultaneously. That is, the unloading suction component loads the first batch of PCBA5 into the test fixture 12 for the first batch of testing, while the loading suction component 41 loads the second batch of PCBA5 into the buffer fixture 13 for buffering. In subsequent continuous functional tests, the loading and unloading suction components 41 and 41 will load or unload PCBA5 separately to achieve overall automation of the PCBA5 testing process.
[0043] In a preferred embodiment, positioning plates are provided between the feeding slide 412 and the feeding adsorption member 41, and between the unloading slide 422 and the unloading adsorption member. The positioning plates have waist-shaped holes. The feeding adsorption member 41 or the unloading adsorption member is detachably connected to the positioning plate at the waist-shaped hole. The feeding adsorption member 41 and the unloading adsorption member can adjust the position of adsorbing PCBA5 to adapt to PCBA5 of different sizes.
[0044] In the continuous testing of PCBA5, the first batch of PCBA5 is placed in test fixture 12, and the second batch of PCBA5 is placed in buffer fixture 13. It is understood that the specific batch numbers (first batch, second batch, etc.) are only relative to the testing order of each PCBA5. Before testing, buffer component 3 moves along movement path 11 and approaches buffer fixture 13. Buffer component 3 attracts the second batch of PCBA5 within buffer fixture 13, and then pulls the second batch of PCBA5 away from buffer fixture 13. The pressing component moves along movement path 11 to test fixture 12 and presses down on the PCBA5 within test fixture 12. The first batch of PCBA5 completes its functional test.
[0045] Subsequently, the pressing component moves away from the test fixture 12 along the moving path 11 to release the first batch of PCBA5. The feeding rack 43 drives the loading and unloading suction components 41 and 42 to approach the test box 21. The loading suction component 41 has a third batch of PCBA5 adsorbed at its position. The loading drive component 411 drives the loading suction component 41 to descend to the buffer fixture 13, where it releases the third batch of PCBA5 and places it into the buffer fixture 13 for buffering. The unloading drive component 421 drives the unloading suction component to descend to the test fixture 12, where it adsorbs the PCBA5 in the test fixture 12 to unload the first batch of PCBA5. The loading and unloading suction components operate simultaneously, one picking up and one putting down. The feeding component 4 synchronously realizes loading and unloading, which helps to shorten the testing time and thus improve overall efficiency and production capacity.
[0046] After the loading and adsorption component 41 loads the third batch of PCBA5, the buffer component 3 conveys the adsorbed second batch of PCBA5 along the moving path 11 to the test fixture 12, then returns to the buffer fixture 13 and adsorbs the third batch of PCBA5 within the buffer fixture 13. The third batch of PCBA5 then leaves the buffer fixture 13. The pressing component then moves again along the moving path 11 to the test fixture 12 and presses down to test the second batch of PCBA5. The second PCBA5 completes the functional test. By repeating the above operation, continuous functional testing can be achieved, which helps to improve testing efficiency.
[0047] Example 2:
[0048] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the test component 2 and the cache component 3 of this utility model. Please refer to [link / reference]. Figure 3 .
[0049] In this embodiment, the pressing component 22 includes a test base 221, which is slidably mounted on the frame 1 along the moving path 11. A pressing plate 222 is slidably mounted on the test base 221. The pressing plate 222 can move up and down relative to the test base 221. The pressing plate 222 is connected to a first lifting drive component 223. Specifically, the first lifting drive component 223 is preferably, but not limited to, a first lifting cylinder. The output end of the first lifting drive component 223 is connected to the pressing plate 222 to drive the pressing plate 222 to press down the PCBA5 in the test fixture 12 for functional testing.
[0050] As shown in some specific embodiments, the test seat 221 is provided with a first guide seat 2231, and a first guide rod 2232 passes through the first guide seat 2231. The first guide rod 2232 is slidably connected to the first guide seat 2231. Specifically, one end of the first guide rod 2232 along the axial direction is connected to the lower pressure plate 222, and the other end is connected to the output end of the first lifting drive 223. The first lifting drive 223 can drive the lower pressure plate 222 to move up and down via the first guide rod 2232. The first guide rod 2232 and the first guide seat 2231 cooperate with each other to play a guiding role in the lifting and lowering movement of the lower pressure plate 222.
[0051] The test stand 221 is connected to a first sliding drive 224 for moving the test stand 221 along the movement path 11 to approach or move away from the test fixture 12. During testing, the first sliding drive 224 drives the test stand 221 to move along the movement path 11 to the test fixture 12, where the lower pressure plate 222 is located above the test fixture 12. The first lifting drive 223 drives the lower pressure plate 222 to descend via the first guide rod 2232 and presses down on the PCBA5 inside the test fixture 12. The test box 21 and the lower pressure plate 222 perform functional testing on the PCBA5. After the test is completed, the first lifting drive 223 drives the lower pressure plate 222 to rise and return to its original position via the first guide rod 2232, and the first sliding drive 224 drives the lower pressure plate 222 to move away from the test fixture 12 along the movement path 11. The buffer assembly 3 can place the adsorbed PCBA5 inside the test fixture 12 to await the next batch of tests by the test assembly 2.
[0052] In a preferred embodiment, the buffer assembly 3 includes a buffer base 31, which is slidably disposed on the frame 1 along the moving path 11. A buffer adsorption component 33 is slidably disposed on the buffer base 31. Specifically, the buffer adsorption component 33 is preferably, but not limited to, a buffer suction cup. The buffer suction cup can vacuum adsorb the PCBA5 to adsorb the PCBA5 in the buffer fixture 13 during testing, thereby reducing the influence of the PCBA5 in the buffer fixture 13 on the test results at the test fixture 12.
[0053] The buffer adsorption component 33 is connected to a second lifting drive component 34. Specifically, the second lifting drive component 34 is preferably, but not limited to, a second lifting cylinder. The second lifting drive component 34 can be set on the buffer seat 31, and its output end is driven to the buffer adsorption component 33 to drive the buffer adsorption component 33 to move up and down relative to the buffer seat 31.
[0054] As shown in some specific embodiments, a second guide seat 341 is provided on the buffer seat 31, and a second guide rod 342 is passed through the second guide seat 341. The second guide rod 342 is slidably connected to the second guide seat 341. Specifically, one end of the second guide rod 342 is connected to the second lifting drive member 34, and the other end is connected to the buffer adsorption member 33. The second guide rod 342 and the second guide seat 341 play a guiding role in the lifting and lowering movement of the buffer adsorption member 33.
[0055] Furthermore, an installation strip 311 is provided between the buffer adsorption component 33 and the second guide rod 342. Specifically, the installation strip 311 is located on the corresponding end of the second guide rod 342, and the installation strip 311 is detachably connected to the buffer adsorption component 33. An adjustment hole 3111 is provided through the installation strip 3111. This adjustment hole 3111 is specifically an oblong hole. The buffer adsorption component 33 can be assembled with the installation strip 3111 at the adjustment hole 3111 by bolts. The setting of the adjustment hole 3111 allows the buffer adsorption component 33 to be adjusted to the position on the installation strip 311 according to the size of the PCBA5, and the buffer adsorption component 33 stably adsorbs the PCBA5.
[0056] The buffer seat 31 is connected to a second sliding drive member 32, which drives the buffer seat 31 to move along the moving path 11.
[0057] Before testing the first batch of PCBA5, the second sliding drive 32 drives the buffer seat 31 to move along the movement path 11 towards the buffer fixture 13. When the buffer seat 31 moves to the buffer fixture 13, the second lifting drive 34 drives the mounting strip 311 and the buffer suction member 33 to descend, and the buffer suction member 33 suctions the second batch of PCBA5 inside the buffer fixture 13. The first sliding drive 224 then drives the test seat 221 to move along the movement path 11 towards the test fixture 12. When the test seat 221 moves to the test fixture 12, the first lifting drive 223 drives the lower pressure plate 222 to descend and press the first batch of PCBA5. The test box 21 tests the first batch of PCBA5. After the test is completed, the test assembly 2 exits.
[0058] The feeding assembly 4 performs loading and unloading operations. The unloading adsorption unit adsorbs the first batch of PCBA5s into the test fixture 12 for unloading, while the loading adsorption unit 41 loads the third batch of PCBA5s into the buffer fixture 13. The second sliding drive unit 32 drives the buffer seat 31 to move along the moving path 11 to the test fixture 12. The second lifting drive unit 34 drives the buffer adsorption unit 33 to descend and place the second batch of PCBA5s into the test fixture 12. The first sliding drive unit 224 then drives the test seat 221 to move along the moving path 11 to the test fixture 12 to test the second batch of PCBA5s.
[0059] Test component 2 and cache component 3 work together to perform continuous testing on each batch of PCBA5, ensuring the orderliness and smoothness of the testing process and shortening the testing time.
[0060] Example 3:
[0061] The difference between this embodiment and the above embodiments is that, please refer to [link / reference needed]. Figure 3 and Figure 4 In this embodiment, multiple cache fixtures 13 and test fixtures 12 are provided.
[0062] As shown in some specific embodiments, two cache fixtures 13 and two test fixtures 12 are provided. It is understood that this is not a specific limitation on the number of cache fixtures 13 and test fixtures 12, and those skilled in the art can adjust the number according to actual production needs. The two cache fixtures 13 are located between the two test fixtures 12 to facilitate the orderly movement of the test component 2 and the cache component 3.
[0063] Specifically, there are two loading adsorption components 41 and two unloading adsorption components. The loading adsorption component 41 is set to correspond with the buffer fixture 13, and the unloading adsorption component is set to correspond with the test fixture 12.
[0064] Similarly, the buffer seat 31 is correspondingly set with the buffer fixture 13. That is, there are two buffer seats 31 in this embodiment. In a preferred embodiment, the second sliding drive member 32 includes a second drive wheel 321. The second drive wheel 321 is driven by a second rotary drive member 322 for driving the second drive wheel 321 to rotate. Specifically, the second rotary drive member 322 is preferably, but not limited to, a second motor. The second rotary drive member 322 can be set on the frame 1.
[0065] A second driven wheel 323 is provided at one end of the second drive wheel 321 along the movement path 11. The second driven wheel 323 is rotatably connected to the frame 1. A second transmission belt 324 is fitted on the second driven wheel 323 and the second drive wheel 321. The second drive wheel 321 drives the second driven wheel 323 to rotate via the second transmission belt 324. Specifically, the two buffer seats 31 are respectively connected to the second transmission belt 324 so that when the second rotary drive member 322 drives the second drive wheel 321 to rotate, the second drive wheel 321 drives the second driven wheel 323 to rotate via the second transmission belt 324. When the second transmission belt 324 rotates and conveys, it drives the two buffer seats 31 to move closer or further away from each other, which can realize the synchronous movement of the two buffer seats 31. The second sliding drive member 32 is driven by a single drive source, which is beneficial to cost saving.
[0066] As shown in some specific embodiments, a buffer guide rail 35 is provided between the buffer base 31 and the frame 1. The buffer guide rail 35 is arranged along the direction of the moving path 11. The buffer base 31 and the buffer guide rail 35 are slidably connected to guide the movement of the buffer base 31.
[0067] In a preferred embodiment, the test seat 221 is correspondingly arranged with the test fixture 12. At this time, the two buffer seats 31 are located between the two test seats 221. Specifically, the test seat 221 is slidably connected to the buffer guide rail 35, and both the test seat 221 and the buffer seat 31 slide along the buffer guide rail 35. As shown in some specific embodiments, the first sliding drive member 224 includes a first drive wheel 2241. The first drive wheel 2241 is driven by a first rotary drive member 2242 for driving the second drive wheel 321 to rotate. Specifically, the first rotary drive member 2242 preferably, but not limited to, uses a first motor, and the first rotary drive member 2242 can be arranged on the frame 1.
[0068] A first driven wheel 2243 is provided at one end of the first drive wheel 2241 along the movement path 11. The first driven wheel 2243 is rotatably connected to the frame 1. A first transmission belt 2244 is sleeved on the first driven wheel 2243 and the first drive wheel 2241. Specifically, the first transmission belt 2244 is arranged parallel to the second transmission belt 324. The first drive wheel 2241 drives the first driven wheel 2243 to rotate via the first transmission belt 2244. Specifically, the two test seats 221 are respectively connected to the first transmission belt 2244 so that when the first rotary drive member 2242 drives the first drive wheel 2241 to rotate, the first drive wheel 2241 drives the first driven wheel 2243 to rotate via the first transmission belt 2244. When the first transmission belt 2244 rotates and conveys, it drives the two buffer seats 31 to move closer or further away from each other, which can realize the synchronous movement of the two test seats 221. The first sliding drive member 224 is driven by a single drive source, which helps to save costs.
[0069] Before testing the first batch of PCBA5, the first batch of PCBA5 is loaded into two test fixtures 12, and the second batch of PCBA5 is loaded into two buffer fixtures 13. The second rotary drive 322 drives the second transmission belt 324 via the second drive wheel 321. The second transmission belt 324 drives the second driven wheel 323 to rotate and drive the two buffer seats 31 to move closer to each other along the movement path 11 to the corresponding buffer fixtures 13, where the buffer assembly 3 holds the second batch of PCBA5. The second rotary drive 322 then reverses, and the second transmission belt 324 drives the two buffer seats 31 to move further apart so that the buffer assembly 3 holds the second batch of PCBA5 away from the buffer fixtures 13.
[0070] The first rotary drive 2242 drives the first transmission belt 2244 via the first drive wheel 2241. The first transmission belt 2244 drives the first driven wheel 2243 to rotate and drive the two test seats 221 to move closer to each other, so that they move along the moving path 11 to the corresponding test fixtures 12. The test assembly 2 performs functional tests on the first batch of PCBA5 in the corresponding test fixtures 12. After the functional test is completed, the first rotary drive 2242 reverses, and the first transmission belt 2244 drives the two test seats 221 to move away from each other, so that they leave the corresponding test fixtures 12. The unloading adsorption component can unload the first batch of PCBA5.
[0071] The first sliding drive 224 drives the test seat 221 to move along the moving path 11 and approach the test fixture 12. When the test seat 221 moves to the test fixture 12, the first lifting drive 223 drives the lower pressure plate 222 to descend and press the first batch of PCBA5. The test box 21 tests the first batch of PCBA5. After the test is completed, the test assembly 2 exits.
[0072] The first sliding drive 224 drives the two test seats 221 to move synchronously, and the second sliding drive 32 drives the two buffer seats 31 to move synchronously, which helps to further improve the testing efficiency. The PCBA5 automated testing mechanism can simultaneously buffer and test multiple PCBA5s.
