Description

Technical Field

[0001] This invention relates to the field of battery testing equipment technology, and more specifically to an automatic battery testing process. Background Technology

[0002] After the battery is manufactured, leakage detection is required to ensure its safety and stability.

[0003] In existing battery testing equipment, one method is to test each battery individually, which results in extremely low testing efficiency. Another method involves batch testing of batteries first, followed by individual retesting of the failed batches. This retesting requires another round of testing in the battery testing equipment, which also prolongs the testing time and reduces testing efficiency. Summary of the Invention

[0004] The first objective of this invention is to address the technical problem of low efficiency in the prior art by providing an automated battery testing process that enables a compact production cycle and improves process efficiency.

[0005] To achieve the above objectives, the present invention provides a battery testing process, including an automatic battery testing system. The battery testing system includes a full testing device and a retesting device. The full testing device includes a full testing transport mechanism, and a feeding conveyor, a transfer mechanism, a full testing buffer mechanism, a full testing test mechanism, a full testing unloading mechanism, and a full testing NG (Not Yet Tested) unloading mechanism arranged along the movement path of the full testing transport mechanism. The retesting device includes a retesting transport mechanism, and a retesting test mechanism, a retesting unloading mechanism, and a retest NG unloading mechanism arranged along the movement path of the retesting transport mechanism. The workpiece of the full testing device is transported to the retesting device through the full testing NG unloading mechanism. The automatic battery testing system implements the following steps:

[0006] S1. Loading: The loading conveyor feeds the workpieces to the testing equipment. The loading conveyor unloads the workpieces to the transfer mechanism via a robotic arm. The workpieces on the transfer mechanism are evenly arranged to form a workpiece group.

[0007] S2. Handling: The workpiece group stored in the transfer mechanism is moved to the test buffer mechanism or the test mechanism through the test handling mechanism; if the test mechanism is fully loaded, the workpiece group in the transfer mechanism is moved to the test buffer mechanism for storage through the test handling mechanism; if the test mechanism is empty, the workpiece group in the transfer mechanism is moved to the test mechanism for testing through the test handling mechanism.

[0008] S3. Complete Testing: The complete testing mechanism tests the workpiece group placed in the testing chamber. If the test is qualified, the complete testing and handling mechanism will transfer the qualified workpiece group to the complete testing and unloading mechanism for unloading. If the test is unqualified, the complete testing and handling mechanism will transfer the unqualified workpiece group to the complete testing and NG test-taking mechanism of the retesting equipment.

[0009] S4. Retesting: The retesting and transporting mechanism transports the workpiece group on the NG test mechanism to the retesting and testing mechanism as individual workpieces. The workpieces that pass the test are transported to the retesting and unloading mechanism, and the workpieces that fail the test are transported to the retesting and unloading mechanism.

[0010] This solution arranges the various mechanisms of the overall testing equipment along the movement path of the overall testing and transport mechanism, and the various mechanisms of the retesting equipment along the movement path of the retesting and transport mechanism. This makes the workpiece movement station within the automatic battery testing system compact and the movement and transport efficiency high. Furthermore, the overall testing equipment first performs batch testing on the workpiece group, and then the retesting equipment retests the unqualified workpiece group. During the retesting, the retesting will not interfere with the testing of the overall testing equipment, thus improving the workpiece testing efficiency.

[0011] The second aspect of this invention aims to solve the technical problem that the transfer mechanism cannot simultaneously perform loading and unloading. Preferably, the transfer mechanism includes two positioning trays and a conveying assembly. The positioning trays include multiple positioning parts, which position and distribute the workpieces on the trays. The positioning trays are staggered, and the conveying assembly is used for the alternating movement of the two positioning trays. Since the transfer mechanism needs to cooperate with the robotic arm of the loading conveyor and the overall transport mechanism, to avoid stagnation in the transfer mechanism, the two positioning trays, which are staggered in height, alternately reciprocate on the conveying assembly. The two positioning trays can simultaneously satisfy the requirements of the robotic arm of the loading conveyor placing workpieces sequentially onto the transfer mechanism, and the overall transport mechanism transporting the workpiece group from the transfer mechanism to the subsequent process.

[0012] Preferably, the overall testing buffer mechanism includes a placement component, a pallet handling component, and a pallet conveying component. The placement component is used to place the overall testing pallet. The pallet handling component is drivenly connected to the pallet conveying component. The two ends of the movement path of the pallet conveying component are a first temporary storage station and a second temporary storage station, respectively. When the pallet handling component is located at the first temporary storage station, it cooperates with the placement component. When the pallet handling component is located at the second temporary storage station, it cooperates with the overall testing transport mechanism. And / or, the overall testing equipment includes two overall testing buffer mechanisms. The two overall testing buffer mechanisms are respectively a pallet temporary storage module for placing empty overall testing pallets and a workpiece temporary storage module for placing pallets containing workpiece groups. This solution allows the pallet handling component to adjust its position between the working positions of the placement component and the overall testing transport mechanism through the pallet conveying component. Furthermore, by setting the two overall testing buffer mechanisms as a pallet temporary storage module and a workpiece temporary storage module, empty overall testing pallets and overall testing pallets containing workpiece groups are stored separately, preventing confusion in the use of overall testing pallets during actual operation.

[0013] The fourth aspect of this invention aims to solve the technical problem of cumbersome switching caused by the need for different clamps to transport pallets and workpieces. Further, the measurement and transport mechanism includes a first motion component and two measurement and execution clamps. The two measurement and execution clamps move linearly on the first motion component. Each measurement and execution clamp includes a pallet clamping part and a workpiece clamping part. The pallet clamping part is used to transport the measurement pallet, and the workpiece clamping part is used to clamp the workpiece. The workpiece clamping part includes multiple workpiece connectors, which respectively act on the measurement pallet to place various workpieces.

[0014] The retesting and handling mechanism includes a second motion component, a pallet handling fixture, and a retesting execution fixture. The pallet handling fixture and the retesting execution fixture move linearly on the second motion component. The retesting execution fixture includes a pallet clamping part and a workpiece clamping part. The pallet clamping part is used to handle the retesting pallet, and the workpiece clamping part is used to clamp the workpiece. The workpiece clamping part includes a workpiece connector, which acts to handle a single workpiece.

[0015] This solution integrates the pallet clamping part and the workpiece clamping part to address the operational positions of the overall measurement and re-measurement handling mechanism. This allows the same overall measurement and re-measurement handling mechanism to quickly switch between workpiece handling and pallet handling modes and perform clamping quickly.

[0016] Preferably, the overall testing mechanism includes a test conveying component, an overall testing moving component, and an overall testing positioning component. The two ends of the conveying path of the test conveying component are a test receiving station and a test working station, respectively. The test working station is located below the overall testing positioning component, and the test receiving station is located within the working range of the overall testing conveying mechanism. The test conveying component is used to drive the overall testing moving component to reciprocate between the test receiving station and the test working station. The overall testing mechanism is equipped with a test lifting module, which drives the overall testing mechanism to move up and down. The overall testing moving component and the overall testing positioning component are sealed to form an overall testing chamber. The overall testing mechanism also includes a gas control component and a leak detection module located on the overall testing positioning component. The leak detection module is used to detect whether the workpiece group in the overall testing chamber has leaked.

[0017] Preferred, The The feeding and conveying mechanism takes 15-20 seconds to distribute materials to the temporary storage and positioning tray of the transfer mechanism via a robotic arm. The testing and measurement moving component of the whole-testing mechanism takes 20-25 seconds to perform testing at the testing work station. The reciprocating motion of the whole-testing moving component between the testing receiving station and the testing work station takes 5-10 seconds. The whole-testing execution fixture used for feeding waits in the transfer mechanism when it is not in operation. When the whole-testing mechanism completes its testing, if the positioning tray of the transfer mechanism is not fully replenished, the material distribution sensor of the transfer mechanism will detect that the positioning tray is fully placed and it will still need to wait for more than 8 seconds. The whole-testing execution fixture used for feeding will then transport the workpiece temporary storage module of the whole-testing buffer mechanism and move the workpiece temporary storage module to the whole-testing mechanism. If the material distribution sensor of the transfer mechanism detects that the positioning tray is fully placed and it will still need to wait for no more than 8 seconds, the whole-testing execution fixture used for feeding will wait for the positioning tray on the transfer mechanism to be fully placed before directly moving the workpiece group on the positioning tray to the whole-testing mechanism.

[0018] Preferably, step S3 further includes the following step:

[0019] S31. The unused test assembly moves to the test receiving station via the test transport assembly, and the test transport mechanism transports the workpiece group into the tray of the test assembly.

[0020] S32. The test moving component moves to the test work station through the test conveying component, so that the test moving component is aligned with the test positioning component. The test moving component moves upward under the action of the test lifting module, so that the test moving component and the test positioning component form a sealed test chamber.

[0021] S33. Activate the gas control component and use the negative pressure module to put the entire test chamber into a negative pressure state. The leakage detection module in the entire test chamber will detect whether there is a leak in the workpiece group in the entire test chamber.

[0022] S34. After the test is completed, the positive pressure module puts the entire test chamber under positive pressure. The test lifting module moves the entire test movable component downward, removing the entire test movable component from the sealed state. The test conveying component then transfers the entire test movable component back to the test receiving station.

[0023] S35. The overall testing and handling mechanism, in conjunction with the test results of the leakage detection module, moves the workpiece group from the test receiving station.

[0024] The third aspect of this invention aims to solve the technical problem that contamination of the tray after workpiece leakage affects the detection effect of the overall testing mechanism. Preferably, in step S35, different transport parts need to be selected according to different test results. When the leakage detection module detects that the workpiece group of the overall testing mechanism has not leaked, the overall testing transport mechanism transports the workpiece group placed on the tray of the overall testing movable component to the overall testing unloading mechanism through the workpiece clamping part; if the leakage detection module detects that the workpiece group of the overall testing mechanism has leaked, the overall testing transport mechanism transports the workpiece group placed on the tray of the overall testing movable component to the overall testing NG test-taking mechanism through the tray clamping part. This solution realizes the transport of different objects through the workpiece clamping part and the tray clamping part set in the overall testing transport mechanism. When the leakage detection module detects that the corresponding workpiece group has leaked, it will cause the tray to be contaminated. The leaking workpiece group, along with the tray, is moved out of the overall testing mechanism. Then, the tray clamping part of the overall testing transport mechanism transports a clean tray to the tray temporary storage module and places it back on the overall testing movable component of the overall testing mechanism, ensuring the accuracy of the test results.

[0025] Preferably, step S4 further includes the following step:

[0026] S41. A test pallet containing a group of defective workpieces is placed on the NG test-to-be-tested mechanism. The material conveying component transports the test pallet to the working range of the retesting and handling mechanism through the NG test-to-be-tested conveying component. The retesting and handling mechanism moves to the retesting and receiving station through the retesting and handling component. The workpiece is placed on the retesting and handling component by the workpiece clamping part of the retesting and handling mechanism using a single-piece clamping method.

[0027] S42. The retesting active component moves to the retesting work station through the retesting transport component. The retesting active component moves upward through the retesting lifting module, so that the retesting active component and the retesting positioning component form a sealed retesting chamber.

[0028] S43. Activate the gas control component of the retesting mechanism to perform vacuum treatment on the retesting chamber, and the leak detection module detects whether there is a leak in the workpiece inside the retesting chamber.

[0029] S44. After the leak detection module completes the test, the gas control component applies positive pressure. The retesting active component moves downward through the retesting lifting module, causing the retesting active component to leave the sealed state. The retesting active component is then transferred back to the retesting receiving station by the retesting conveying component.

[0030] S45. The retesting and handling mechanism, based on the test results of the leakage detection module, handles the workpiece at the retesting receiving station. If the retesting leakage detection module detects no leakage, the workpiece clamping part of the retesting execution fixture handles the workpiece to the retesting unloading mechanism. If the retesting leakage detection module detects leakage, the pallet clamping part of the retesting execution fixture handles the retesting pallet containing the workpiece to the retesting unloading mechanism.

[0031] The beneficial effects of this invention are as follows: by arranging the various mechanisms of the overall testing equipment along the movement path of the overall testing and conveying mechanism, and the various mechanisms of the retesting equipment along the movement path of the retesting and conveying mechanism, the workpieces move in a compact manner within the automatic battery testing system, resulting in high movement and conveying efficiency. Furthermore, the overall testing equipment first performs batch testing on the workpiece groups, and then the retesting equipment retests the unqualified workpiece groups. During the retesting process, the overall testing equipment is not interfered with, thus improving the workpiece testing efficiency. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0037] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components.

[0038] Example 1

[0039] like Figure 1 As shown, this embodiment provides a battery testing process, including an automatic battery testing system. The battery testing system includes a full testing device and a retesting device. The full testing device includes a full testing transport mechanism 1, and a feeding conveying mechanism 2, a transfer mechanism 3, a full testing buffer mechanism 4, a full testing testing mechanism 5, a full testing unloading mechanism 101, and a full testing NG (Not Yet Tested) waiting mechanism 6 arranged along the movement path of the full testing transport mechanism 1. The retesting device includes a retesting transport mechanism 7, and a retesting testing mechanism, a retesting unloading mechanism 102, and a retesting NG unloading mechanism 9 arranged along the movement path of the retesting transport mechanism 7. The workpiece of the full testing device is transported to the retesting device through the full testing NG waiting mechanism 6. The automatic battery testing system implements the following steps:

[0040] S1. Loading: The loading conveyor 2 loads the workpieces into the testing equipment. The loading conveyor 2 unloads the conveyed workpieces to the transfer mechanism 3 through the robotic arm 21. The workpieces on the transfer mechanism 3 are evenly arranged to form a workpiece group.

[0041] S2. Handling: The workpiece group stored in the transfer mechanism 3 is moved to the test buffer mechanism 4 or the test mechanism 5 through the test handling mechanism 1; if the test mechanism 5 is fully loaded, the workpiece group in the transfer mechanism 3 is moved to the test buffer mechanism 4 for storage through the test handling mechanism 1; if the test mechanism 5 is empty, the workpiece group in the transfer mechanism 3 is moved to the test mechanism 5 for testing through the test handling mechanism 1.

[0042] S3, Overall Testing: The overall testing mechanism 5 tests the workpiece group placed in the testing chamber. If the test is qualified, the overall testing and handling mechanism 1 transfers the qualified workpiece group to the overall testing and unloading mechanism 101 for unloading. If the test is unqualified, the overall testing and handling mechanism 1 transfers the unqualified workpiece group to the overall testing and NG testing mechanism 6 of the retesting equipment.

[0043] S4. Retesting: The retesting and transporting mechanism 7 transports the workpiece group on the whole test NG test mechanism 6 to the retesting and testing mechanism as individual workpieces. The single workpieces that pass the test are transported to the retesting and unloading mechanism 102, and the single workpieces that fail the test are transported to the retesting and unloading mechanism 9.

[0044] The various mechanisms of the overall testing equipment are arranged along the movement path of the overall testing and transport mechanism 1, and the various mechanisms of the retesting equipment are arranged along the movement path of the retesting and transport mechanism 7. This makes the workpiece movement station within the battery automatic testing system compact and the movement and transport efficiency high. Furthermore, the overall testing equipment first performs batch testing on the workpiece group, and then the retesting equipment retests the unqualified workpiece group, thereby improving the workpiece testing efficiency.

[0045] To address the technical problem that the transfer mechanism 3 cannot simultaneously perform loading and unloading, the transfer mechanism 3 in this embodiment includes two positioning trays 31 and a conveying assembly. Each positioning tray 31 includes multiple positioning parts, which position and distribute the workpieces on the trays. The positioning trays 31 are staggered, and the conveying assembly is used for the alternating movement of the two positioning trays 31. Since the transfer mechanism 3 needs to cooperate with the robotic arm 21 of the loading conveying mechanism 2 and the overall measurement and handling mechanism 1, to avoid stagnation, the two staggered positioning trays 31 alternately reciprocate on the conveying assembly. The two positioning trays 31 can simultaneously satisfy the requirements of the robotic arm 21 of the loading conveying mechanism 2 placing workpieces sequentially onto the transfer mechanism 3, and the overall measurement and handling mechanism 1 transporting the workpiece group from the transfer mechanism 3 to subsequent processes.

[0046] like Figure 3 As shown, the test buffer mechanism 4 in this embodiment includes a placement component 44, a pallet handling component 45, and a pallet conveying component 43. The placement component 44 is used to place the test pallet. The pallet handling component 45 is connected to the pallet conveying component 43 in a transmission manner. The two ends of the movement path of the pallet conveying component 43 are a first temporary storage station 431 and a second temporary storage station 432, respectively. When the pallet handling component 45 is located at the first temporary storage station 431, it cooperates with the placement component 44. When the pallet handling component 45 is located at the second temporary storage station 432, it cooperates with the test handling mechanism 1.

[0047] The testing equipment includes two testing buffer mechanisms 4. The two buffer mechanisms 4 are respectively a pallet storage module 41 for placing empty testing pallets and a workpiece storage module 42 for placing pallets containing workpiece sets. This solution uses a pallet conveying component 43 to allow the pallet handling component 45 to adjust its position between the placement component 44 and the testing handling mechanism 1. Furthermore, by setting the two testing buffer mechanisms 4 as a pallet storage module 41 and a workpiece storage module 42 respectively, empty testing pallets and testing pallets containing workpiece sets are stored separately, preventing confusion in the use of the testing pallets during actual operation.

[0048] When the whole testing mechanism is working, the pallet handling component 45 of the pallet temporary storage module 41 takes an empty whole testing pallet from the placement component 44 and transports the whole testing pallet to the first temporary storage station 431 through the pallet conveying component 43. The whole testing handling mechanism 1 transports the workpiece group of the transfer mechanism 3 to the pallet handling component 45 through the workpiece clamping part. The pallet handling component 45 of the workpiece temporary storage module 42 is transported to the first temporary storage station 431 through the pallet conveying component 43. The whole testing handling mechanism 1 transports the whole testing pallet with the workpiece group placed on the pallet temporary storage module to the pallet handling component 45 of the workpiece temporary storage module 42 through the pallet conveying component 43.

[0049] The cooperation relationship between the pallet temporary storage module 41 and the workpiece temporary storage module 42 is as follows: the default position when the pallet transport component 45 of both the pallet temporary storage module 41 and the workpiece temporary storage module 42 is not in operation is the first temporary storage station 431. The pallet transport component 45 of the pallet temporary storage module 41 is in standby at the first temporary storage station 431, but it is also in standby with an empty test pallet placed on it. The pallet transport component 45 of the workpiece temporary storage module 42 is in standby at the first temporary storage station 431, but it is not in standby with a test pallet placed on it.

[0050] The workpiece group is transferred from the transfer mechanism 3 to the pallet temporary storage module 41 by the workpiece clamping part. After the material sensor of the pallet temporary storage module 41 detects that the pallet handling component 45 has finished loading, the workpiece handling fixture moves the workpiece group on the pallet temporary storage module 41 to the pallet handling component 45 of the workpiece temporary storage module 42 through the pallet clamping part. The pallet handling component 45 of the workpiece temporary storage module 42 transports the workpiece group to the second temporary storage station 432 through the pallet conveying component 43. The pallet handling component 45 places the workpiece group on the placement component 44 for storage.

[0051] like Figure 3 As shown, in this embodiment, the placement component 44 includes a stacking platform and a support portion disposed on the stacking platform for pallet support. The side of the pallet in this application is provided with an insertion interface. The support portion includes a retractable insertion plate. The insertion plates on both sides of the stacking platform are inserted into the insertion interface of the bottom pallet, thus supporting all the pallets stacked above. The pallet handling mechanism includes a bearing plate and a lifting drive component. The bearing plate moves up and down via the lifting drive component. The pallet handling mechanism retrieves and places pallets into the temporary storage component.

[0052] The lifting drive unit drives the support plate to abut against the bottommost pallet of the stack. At this time, the insertion plate of the support part disengages from the side insertion interface of the whole pallet. The stacked pallets are supported by the pallet handling mechanism. The lifting drive unit moves the stacked pallets down, and the support part extends out of the insertion interface to align with the second to last pallet insertion interface at the bottom and then inserts it. The bottommost pallet of the stack of placement component 44 is then removed.

[0053] The lifting drive unit drives the support plate, which holds a pallet, to abut against the bottom pallet stacked on the stacking platform. The insertion plate of the support part disengages from the side insertion interface of the entire pallet. At this time, the stacked pallets are supported by the pallet handling mechanism. The lifting drive unit moves the stacked pallets upward, and the support part extends its insertion interface to align with the insertion interface of the pallet originally placed on the support plate and then inserts it. The pallet on the support plate is then placed on the placement component 44.

[0054] Example 2

[0055] like Figure 1 As shown, the measurement and handling mechanism 1 of this embodiment includes a first motion component 12 and two measurement execution fixtures 11. The two measurement execution fixtures 11 move linearly on the first motion component 12. Each measurement execution fixture 11 includes a pallet clamping part and a workpiece clamping part. The pallet clamping part is used to transport the measurement pallet, and the workpiece clamping part is used to clamp the workpiece. The workpiece clamping part includes multiple workpiece connectors, and the multiple workpiece connectors respectively act on the measurement pallet to place each workpiece.

[0056] The overall testing and handling mechanism 1 is equipped with two overall testing execution fixtures 11, one for loading and the other for unloading. The fixed path points for the loading execution fixture 11 are the transfer mechanism 3, the first temporary storage stations 431 of the overall testing temporary storage mechanism, and the test receiving stations 531 of the overall testing mechanism 5. The fixed path points for the unloading execution fixture 11 are the test receiving stations 531 of the overall testing mechanism 5, the overall testing NG test-pending mechanism 6, and the overall testing unloading mechanism 101, enabling the loading and unloading execution fixtures to cooperate. Furthermore, the overall testing execution fixture 11 is calibrated at each path point, and a corresponding position sensor is set at each fixed path point. When the overall testing execution fixture 11 moves via the first motion component 12, it can only stop at each fixed path point, and each movement can accurately reach the fixed path point without positioning.

[0057] The retesting and handling mechanism 7 includes a second motion component 73, a pallet handling fixture 71, and a retesting execution fixture 72. The pallet handling fixture 71 and the retesting execution fixture 72 move linearly on the second motion component 73. The retesting execution fixture 72 includes a pallet clamping part and a workpiece clamping part. The pallet clamping part is used to handle the retesting pallet, and the workpiece clamping part is used to clamp the workpiece. The workpiece clamping part includes a workpiece connector, which acts to handle a single workpiece.

[0058] The retesting and handling mechanism 7 is equipped with a pallet handling fixture 71 and a retesting execution fixture 72. The fixed path points operated by the pallet handling fixture 71 are the NG test unit 6 and the NG unloading mechanism 103. The fixed path points operated by the retesting execution fixture 72 are the NG test unit 6, the NG unloading mechanism 9, the various retesting receiving stations 831 of the retesting detection mechanism 8, and the retesting unloading mechanism 102, enabling the pallet handling fixture 71 and the retesting execution fixture 72 to work together. The pallet handling fixture 71 and the retesting execution fixture 72 are calibrated at each path point, and corresponding position sensors are set at each fixed path point. When the pallet handling fixture 71 and the retesting execution fixture 72 move via the first motion component 12, they can only stop at each fixed path point, and each movement can accurately reach the fixed path point without positioning.

[0059] Example 3

[0060] like Figure 2As shown, the overall testing mechanism 5 in this embodiment includes a test conveying component 53, an overall testing moving component 51, and an overall testing positioning component 52. The two ends of the conveying path of the test conveying component 53 are a test receiving station 531 and a test working station 532, respectively. The test working station 532 is located below the overall testing positioning component 52, and the test receiving station 531 is located within the working range of the overall testing conveying mechanism 1. The test conveying component 53 is used to drive the overall testing moving component 51 to reciprocate between the test receiving station 531 and the test working station 532. The overall testing mechanism is provided with a test lifting module, which drives the overall testing mechanism to move up and down. The overall testing moving component 51 and the overall testing positioning component 52 are sealed to form an overall testing chamber. The overall testing mechanism 5 also includes a gas control component and a leakage detection module disposed on the overall testing positioning component 52. The leakage detection module is used to detect whether the workpiece group in the overall testing chamber has leaked.

[0061] In this embodiment, the feeding and conveying mechanism 2 distributes materials to the temporary storage and positioning tray 31 of the transfer mechanism 3 via the robotic arm 21 for 15-20 seconds. The testing and inspection mechanism's testing and inspection active component 51 performs testing at the testing work station 532 for 20-25 seconds. The testing and inspection active component 51 reciprocates between the testing receiving station 531 and the testing work station 532 for 5-10 seconds. When the loading and unloading execution fixture 11 is not in operation, it waits in the transfer mechanism 3. When the overall testing mechanism completes the test, if the positioning tray 31 of the transfer mechanism 3 is not fully replenished, the material distribution sensor of the transfer mechanism 3 will detect that the positioning tray 31 is fully placed and it will take more than 8 seconds. The loading and unloading execution fixture 11 will then be transported to the workpiece temporary storage module 42 of the overall testing buffer mechanism and the workpiece temporary storage module 42 will be moved to the overall testing mechanism. If the material distribution sensor of the transfer mechanism 3 detects that the positioning tray 31 is fully placed and it will take no more than 8 seconds, the loading and unloading execution fixture 11 will wait for the positioning tray 31 on the transfer mechanism 3 to be fully placed before directly moving the workpiece group on the positioning tray 31 to the overall testing mechanism.

[0062] In this embodiment, the material distribution sensor of the transfer mechanism 3 makes an estimate of the placement time. Both the positioning tray 31 and the full-load tray are structures that can hold 6 workpieces. If there are fewer than 4 workpieces on the positioning tray 31, the material distribution sensor will identify that it will take more than 8 seconds for the positioning tray 31 to be fully placed.

[0063] The retesting mechanism in this embodiment has the same structural composition as the overall testing mechanism. In practical applications, since the retesting tray only needs to hold one workpiece, the volume of the retesting mechanism can be set to be smaller.

[0064] Example 4

[0065] Based on the technology of Embodiment 1, S3 of this embodiment further includes the following steps:

[0066] S31, the unused test assembly 51 is moved to the test receiving station 531 by the test conveying assembly 53, and the test transport mechanism 1 transports the workpiece group into the tray of the test assembly 51.

[0067] S32, the whole test moving component 51 is moved to the test work station 532 through the test conveying component 53, so that the whole test moving component 51 is aligned with the whole test positioning component 52. The whole test moving component 51 moves upward under the action of the test lifting module, so that the whole test moving component 51 and the whole test positioning component 52 form a sealed whole test chamber.

[0068] S33. Activate the gas control component and use the negative pressure module to put the entire test chamber into a negative pressure state. The leakage detection module in the entire test chamber will detect whether there is a leak in the workpiece group in the entire test chamber.

[0069] S34. After the test is completed, the positive pressure module puts the entire test chamber into a positive pressure state, the test lifting module moves the entire test movable component 51 downward, and removes the entire test movable component 51 from the sealed state. The entire test movable component 51 is then transferred back to the test receiving station 531 through the test conveying component 53.

[0070] S35, the whole test and handling mechanism 1, in conjunction with the test results of the leakage detection module, handles the workpiece group at the test receiving station 531.

[0071] To address the technical issue of workpiece leakage contamination affecting the testing effectiveness of the entire testing mechanism, S35 requires selecting different transport points based on the test results. When the leakage detection module detects no leakage in the workpiece group of the entire testing mechanism 5, the entire testing transport mechanism 1 transports the workpiece group placed on the pallet of the entire testing movable component 51 to the entire testing unloading mechanism 101 via the workpiece clamping part. If the leakage detection module detects a leakage in the workpiece group of the entire testing mechanism 5, the entire testing transport mechanism 1 transports the workpiece group placed on the pallet of the entire testing movable component 51 to the entire testing NG test-taking mechanism 6 via the pallet clamping part. This solution achieves the transport of different objects through the workpiece clamping part and pallet clamping part set in the entire testing transport mechanism 1. When the leakage detection module detects a leakage in the corresponding workpiece group, the pallet will become contaminated. The leaking workpiece group, along with the pallet, is moved out of the entire testing mechanism 5. Then, the pallet clamping part of the entire testing transport mechanism 1 transports a clean pallet to the pallet temporary storage module and places it back on the entire testing movable component 51 of the entire testing mechanism 5, ensuring the accuracy of the test results.

[0072] The structure of the NG test unit 6 is the same as that of the test temporary storage unit, but the placement is different. The placement component of the NG test unit 6 is located within the working range of the test transport mechanism. The test transport mechanism directly stacks the test tray containing the group of workpieces detected as leaking onto the placement component. The tray conveying component of the NG test unit transports the tray transport component to the working range of the retest transport mechanism.

[0073] In addition, the edges of the stacked test trays or retest trays are provided with limiting bosses to prevent the workpieces placed on top from being squeezed when the test trays or retest trays are stacked.

[0074] S4 also includes the following steps:

[0075] S41. A test tray containing a group of defective workpieces is placed on the NG test-to-be-tested mechanism 6. The material conveying component transports the test tray to the working range of the retesting and handling mechanism 7 through the NG test-to-be-tested conveying component. The retesting and handling mechanism moves to the retesting and receiving station 831 through the retesting and handling component. The workpiece is placed on the retesting and handling component 81 by the workpiece clamping part of the retesting and handling mechanism 7 in a single-piece clamping manner.

[0076] S42, the retesting active component 81 moves to the retesting work station 832 through the retesting transport component, and the retesting active component 81 moves upward through the retesting lifting module, so that the retesting active component 81 and the retesting positioning component 82 form a sealed retesting chamber;

[0077] S43. Activate the gas control component of the retesting mechanism to perform vacuum treatment on the retesting chamber, and the leak detection module detects whether there is a leak in the workpiece inside the retesting chamber.

[0078] S44. After the leak detection module completes the test, the gas control component applies positive pressure. The retesting active component 81 moves downward through the retesting lifting module, causing the retesting active component 81 to leave the sealed state. The retesting active component 81 is then transferred back to the retesting receiving station 831 through the retesting conveying component 83.

[0079] S45, the retesting and handling mechanism 7, based on the test results of the leakage detection module, handles the workpiece at the retesting receiving station 831. If the retesting leakage detection module detects no leakage, the workpiece clamping part of the retesting execution fixture 72 handles the workpiece to the retesting unloading mechanism 102. If the retesting leakage detection module detects leakage, the pallet clamping part of the retesting execution fixture 72 handles the retesting pallet containing the workpiece to the retesting unloading mechanism 9.

[0080] The retesting equipment includes two retesting NG unloading mechanisms 9, which are respectively used to place an empty retesting tray and a retesting tray containing a single workpiece.

[0081] Since the workpieces to be retested are stored in the NG test-testing mechanism, after all the workpieces on the test-testing tray of the NG test-testing mechanism are removed, the test-testing tray is directly transported to the test-testing tray unloading mechanism by the tray transport fixture of the retesting transport mechanism.

[0082] Both the overall testing equipment and the retesting equipment are housed in a sealed operating chamber. The overall testing tray unloading mechanism and the retesting NG unloading mechanism 9 are equipped with drawer structures, which can be used to pull out the overall testing tray unloading mechanism and the retesting NG unloading mechanism from the operating chamber for operation. The operator can remove the overall testing tray from the overall testing tray unloading mechanism from outside the operating chamber, and can also pull out the retesting NG unloading mechanism to put in a new retesting tray and remove the retesting tray containing the leaking workpiece.

[0083] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics in the solutions is not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
