Description

Technical Field

[0001] This invention relates to the field of aging testing technology, and more specifically, to an online aging testing device and testing method. Background Technology

[0002] Aging testing is a method for testing product stability. It can be achieved by testing its functionality or by operating the equipment in extreme or unusual environments. Another aspect of aging testing involves placing the equipment in extreme or unusual environments or exceeding its specifications. As long as the equipment's performance remains stable under these conditions, it will function normally under normal conditions. Aging testing simulates the aging process caused by various factors encountered in real-world use. Common aging tests include light aging, damp heat aging, hot air aging, salt spray testing, vibration testing, and high and low temperature testing. The intensity of these tests is much greater than that of actual environmental parameters, thus shortening the testing time. A short testing period can reveal the aging status of a product after many years of use.

[0003] Aging tests are primarily used for plastic / rubber products (including PP, PVC, natural rubber, etc., especially plastic casings, plastic fasteners, etc.) and coatings / adhesives (industrial coatings, architectural coatings, especially outdoor coatings). In addition, aging tests are also used for other products containing the aforementioned materials or structures, such as electronic devices (mobile phones, circuit boards, etc., especially outdoor electrical equipment, such as photovoltaic inverters and other outdoor products), automotive parts, medical devices, building materials, and other various products.

[0004] Traditional aging tests mainly involve manually transporting the samples to the aging test equipment (such as high-temperature chambers, low-temperature chambers, and light-exposed chambers) for testing. After the test, if the product passes, it is manually transported back to the production line. This results in insufficient product flow and low production efficiency. Therefore, existing technologies employ automated online aging test equipment. This involves using a corresponding conveyor structure to place the aging test equipment on the production line and connecting the conveyor structure to the production line to achieve automatic transfer and transport of the product to the aging test equipment for aging testing.

[0005] In order to facilitate the transport and support of the product, pallets that are easy to transport and corresponding tooling fixtures are needed to support and transport the product under test, so as to provide stable support for the product.

[0006] For some products, comprehensive aging tests are required to test the working capacity of their internal structure and the aging resistance of their external casing under different environments. For example, outdoor photovoltaic inverters need to be tested for their internal circuit system, as well as the quality of their external casing and coating during aging tests. In order to improve testing efficiency, the above-mentioned tests need to be carried out simultaneously.

[0007] However, for test products that are large in size and weight, a stable and comprehensive support system is required during actual transport and testing. Therefore, the contact surface between the fixture and the product is relatively large. During actual testing, connecting cables and other equipment are needed to connect to the product's ports, supply power, and connect to the product's internal circuitry. As a result, the product's posture is relatively fixed during actual testing, making it difficult to change the contact surface with the fixture by controlling the product's rotation. Consequently, the fixture covers a large area of ​​the product during actual testing, reducing the impact of simulated environmental parameters on the product (for example, during high and low temperature tests, the fixture's obstruction can affect the temperature transfer at the corresponding location on the product; during light exposure tests, it can block light from the corresponding area). This affects the comprehensive evaluation of the product's aging resistance performance and is not conducive to subsequent product improvement and further research and development. Summary of the Invention

[0008] The present invention provides an online aging test device and test method, which aims to solve the problem that: in existing test devices, the contact surface between the fixture and the product is large, and the obstruction area of ​​the product is large, thereby reducing the effect of simulated environmental parameters on the product, affecting the comprehensive evaluation of the product's aging resistance performance, and hindering subsequent product improvement and further research and development.

The positioning components include a fixed frame, a positioning plate is provided above the fixed frame, the fixed frame is fixedly installed below the test conveyor, the positioning plate is connected to the fixed frame through a lifting driver, the lifting driver is used to drive the positioning plate to move up and down, the top of the positioning plate is provided with a positioning pin, and the bottom of the support plate is provided with a positioning hole for inserting into the positioning pin.

[0014] In a preferred embodiment, the movable partial positioning assembly further includes a moving drive assembly for driving the movable frame to move. The moving drive assembly includes a docking frame, and multiple docking frames are provided. The docking frames are slidably mounted on the positioning plate. The movable frame extends downward through the support plate. A connector is fixedly connected to the bottom of the movable frame. Each docking frame is provided corresponding to the movable frame. The docking frame is provided with a slot for interlocking with the connector. A moving driver for driving the docking frame to move is installed on the positioning plate.

[0015] In a preferred embodiment, the movable frame includes a roller-type bonding member rotatably mounted on the movable frame. The circumferential surface of the roller-type bonding member contacts the surface of the product to be tested, and the roller-type bonding member rolls relative to the surface of the product to be tested when the movable frame moves.

[0016] In a preferred embodiment, the bonding component includes a track-type bonding component, which includes multiple track plates that are sequentially hinged to form a track structure. The track-type bonding component also includes a track frame and track wheels. The track frame is fixedly mounted on a movable frame, and two sets of track wheels are provided. The track wheels are rotatably mounted on the track frame, and the track structure composed of track plates is fitted onto the two sets of track wheels.

[0017] In a preferred embodiment, the surface of the track plate is provided with an anti-friction plate, which is connected to the track plate by a movable pin. The track plate has a circular hole with a diameter larger than that of the movable pin, and the anti-friction plate moves in contact with the track plate under the connection of the movable pin.

[0018] In a preferred embodiment, a nozzle is provided at the top of the movable frame corresponding to the surface of the mating part, an air passage communicating with the nozzle is provided inside the movable frame, an air supply system is provided on the positioning plate, and the air passage is connected to the air supply system when the plug-in part is mated with the mating frame.

[0019] In a preferred embodiment, a protective shell is fixedly installed on the positioning plate, a docking frame is slidably installed on the protective shell, and the bottom of the docking frame extends into the protective shell. The air supply system includes an air pump, the suction pipe of the air pump is exposed outside the positioning plate, the blowing pipe of the air pump extends into the protective shell, and a baffle plate is fixedly connected to the docking frame at the position corresponding to the opening on the protective shell. The baffle plate is used to block the opening on the protective shell.

[0020] In a preferred embodiment, at least two sets of test conveyors are provided. A return conveyor is provided at the bottom of the test conveyor for transporting empty pallets in the reverse direction. The production line transfer assembly includes a pallet lifter and a multi-directional conveyor. The pallet lifter is used to drive the pallets to rise and fall. The multi-directional conveyor is a double-layer conveying structure corresponding to the test conveyor and the return conveyor, and is located at the end of all test conveyors. The pallet lifter includes a support conveyor frame and a lifting drive. A conveying drive structure is provided on the support conveyor frame for collecting and outputting pallets. The support conveyor frame is used to drive the lifting drive to move up and down between the upper and lower layers of the multi-directional conveyor.

[0021] An online aging test method includes the following steps:

[0022] Step 1: Transport the product to be tested from the production line to an empty pallet on the input multi-directional conveyor.

[0023] Step 2: The multi-directional conveyor distributes the pallets containing the products to be tested to the idle test conveyors, and the test conveyors transport the pallets.

[0024] Step 3: The product to be tested is transported to the first test chamber by the test conveyor and subjected to high-temperature aging test for 30 minutes. During the test, the drive frame and bonding component move along the surface of the corresponding product to be tested.

[0025] Step 4: Transport the product to be tested to the transition zone using the test conveyor and let it stand for 30 minutes;

[0026] Step 5: Transport the product to be tested to the second test chamber via the test conveyor for low-temperature aging test for 30 minutes. During the test, drive the movable frame and the bonding component to move along the surface of the corresponding product to be tested.

[0027] Step 6: Transport the product to be tested, along with the pallet, to the multi-directional conveyor at the output end via the test conveyor. After testing, inspect the product. If it passes, transfer it to the production line for further processing. If it fails, transfer it to the non-conforming area.

[0028] The beneficial effects of this invention are as follows: When the product under test is subjected to aging tests, the invention continuously drives the movable frame and the bonding component to move, thereby changing the actual support position between the bonding component and the product under test. This avoids the support and limiting structures from being in contact with the fixed position of the product under test for a long time, thus preventing obstruction. Especially in high and low temperature tests, the continuous movement of the movable frame and the bonding component allows all surfaces of the product under test to effectively contact the air environment inside the test chamber, achieving comprehensive testing of all surfaces of the product under test, improving the test effect of the product, and reducing the impact of local obstruction on the product test results.

[0040] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0041] Refer to the instruction manual appendix Figures 1 to 9 An online aging test device includes a test chamber 1 and a test conveyor 2. The test chamber 1 is equipped with a first test box 11 and a second test box 12. A transition zone 13 is provided between the first test box 11 and the second test box 12. The first test box 11 is a high-temperature test box, the second test box 12 is a low-temperature test box, and the transition zone 13 is a normal temperature zone. The test conveyor 2 runs through the first test box 11, the transition zone 13, and the second test box 12. A tray 21 is provided on the test conveyor 2. The tray 21 is used to carry the product to be tested. Production line transfer components 3 are provided at both ends of the test conveyor 2. The production line transfer components 3 are connected to the product production line. The production line transfer components 3 are used to transfer the product to be tested from the product production line to the tray 21 on the test conveyor 2. The test conveyor 2 then transports the tray 21, so that the tray 21 carrying the product to be tested passes through the first test box 11, the transition zone 13, and the second test box 12 in sequence.

[0042] It should be noted that this embodiment only uses high temperature testing and low temperature testing as examples of aging tests. Therefore, only the first test chamber 11 and the second test chamber 12 are mentioned. In actual use, other test chambers, such as light exposure test chambers, can be set in the test chamber 1 according to the aging test requirements. The size of the corresponding test instruments and equipment can be selected according to the product production line. The test chamber 1 can be reasonably arranged in the product production line factory. Then, the test conveyor 2 can be set up to make it pass through each test chamber in sequence, thereby forming a production line test, replacing the traditional manual sequential transfer test.

[0043] In the above embodiments, in order to reduce the obstruction of the product surface, this embodiment also provides the following technical solutions, specifically referring to the appendix to the specification. Figure 4 and Figure 6 Movable local positioning components 5 are provided on the tray 21 at positions corresponding to the bottom and sides of the product to be tested. Multiple sets of movable local positioning components 5 are provided on the tray 21 at positions corresponding to the bottom of the product to be tested. The movable local positioning components 5 at the bottom of the product to be tested provide support for the product to be tested, while the movable local positioning components 5 at the sides of the product to be tested provide positioning for the product to be tested to prevent the product from falling off. The movable local positioning components 5 include a movable frame 51, which is movably mounted on the tray 21. The movable frame 51 is provided with a bonding member 52, which is bonded to the surface of the product to be tested. The movable local positioning components 5 also include a moving drive component for driving the movable frame 51 to move. The movable frame 51 and the bonding member 52 move along the surface of their respective products to be tested.

[0044] In the above embodiments, a corresponding linear actuator, such as a cylinder or linear motor, can be installed inside the tray 21. A corresponding air or power supply device can be installed at the position where the tray 21 needs to stop, and connected to the linear actuator. This allows the movable frame 51 and the bonding component 52 to be continuously moved during aging tests in the first test chamber 11 or the second test chamber 12, thereby changing the actual support position of the bonding component 52 and the product under test. This avoids the support and limiting structures from being in prolonged contact with the fixed position of the product under test, thus preventing obstruction. Especially in high and low temperature tests, the continuous movement of the movable frame 51 and the bonding component 52 allows all surfaces of the product under test to effectively contact the air environment inside the test chamber, achieving comprehensive testing of all surfaces. If light testing is involved, auxiliary lighting equipment can be added to the tray 21 or its bottom to fully illuminate the product under test, improving the testing effect and reducing the impact of local obstruction on the test results.

[0045] Furthermore, when the number of products to be tested is large, the space of the first test chamber 11 and the second test chamber 12 can be increased, and the number of test conveyors 2 can be increased to improve the testing efficiency of the products to be tested. Refer to the appendix of the instruction manual. Figures 1 to 3 At least two sets of test conveyors 2 are provided. A return conveyor 22 is provided at the bottom of the test conveyor 2. The return conveyor 22 is used to transport empty pallets 21 in the reverse direction. The production line transfer assembly 3 includes a pallet lifter 31 and a multi-directional conveyor 32. The pallet lifter 31 is used to drive the pallets 21 to rise and fall, that is, the pallet lifter 31 is used to drive the pallets 21 to be transported between the test conveyor 2 and the return conveyor 22, so as to realize the recycling of empty pallets 21 and their reuse. Specifically, the multi-directional conveyor 32 is a double-layer conveying structure corresponding to the test conveyor 2 and the return conveyor 22. The multi-directional conveyor 32 is located at the end of all test conveyors 2. The multi-directional conveyor 32 has multi-directional conveying capability (e.g., ball bearing conveyor belt). Through the test conveyor 2, the pallets 21 can be transported between each set of test conveyors 2, while the pallet lifter 31 transfers the pallets 21 between the upper and lower layers of the multi-directional conveyor 32.

[0046] The pallet lifter 31 includes a support conveyor frame 311 and a lifting driver 312. The support conveyor frame 311 is provided with a conveying drive structure, which is used to collect and output pallets 21. The support conveyor frame 311 is used to drive the lifting driver 312 to move up and down between the upper and lower conveying structures of the multi-directional conveyor 32.

[0047] In actual use, the products to be tested output from the production line are transferred by other conveying structures or robotic arms to pallets 21 on the upper conveying structure of the multi-directional conveyor 32. The multi-directional conveyor 32 then transports the pallets 21 containing the products to be tested to idle test conveyors 2, and then drives the pallets 21 to move to the corresponding test conveyors 2 for conveying and testing. After testing, the products to be tested arrive at the output end of the multi-directional conveyor 32, where other conveying structures or robotic arms remove the products and return them to the production line. Meanwhile, the empty... The pallet 21 is conveyed by the multi-directional conveyor 32 at the output end to the pallet lifter 31 at the output end. The pallet lifter 31 drives the empty pallet 21 to descend, and then the lower conveying structure of the multi-directional conveyor 32 at the output end distributes it to the idle return conveyor 22. The return conveyor 22 then conveys it in reverse to the multi-directional conveyor 32 at the input end. The pallet lifter 31 at the input end then conveys the pallet 21 back to the upper conveying structure of the multi-directional conveyor 32. This allows multiple sets of products to be tested to be tested simultaneously, improving testing efficiency.

[0048] It should be noted that the test conveyor 2, pallet 21, return conveyor 22, pallet lifter 31, and multi-directional conveyor 32 used above are all commonly used conveying equipment in industrial production. This embodiment mainly improves the pallet 21 in the traditional solution. Therefore, this embodiment will not explain the various conveying and transfer equipment in detail. Among them, the various structures located in the first test box 11 and the second test box 12 are mainly metal structures with strong aging resistance. They can maintain good performance during long-term testing.

[0049] In the above embodiments, for some electrical products, power supply and connection to various ports required for testing are also necessary during actual testing. Therefore, the product under test needs to be kept stable when it arrives inside the first test box 11 or the second test box 12 to facilitate the connection of various connectors. Thus, the tray 21 needs to be accurately positioned at the corresponding locations in the first test box 11 and the second test box 12. For this purpose, please refer to the appendix to the instruction manual. Figure 3 , Figure 5 and Figure 6 The bottom of the test conveyor 2 is equipped with positioning components 4 at corresponding positions in the first test box 11, the transition section 13, and the second test box 12. The positioning components 4 include a fixed frame 41 and a positioning plate 42 on the top of the fixed frame 41. The fixed frame 41 is fixedly installed below the test conveyor 2. The positioning plate 42 is connected to the fixed frame 41 through a lifting driver 411. The lifting driver 411 is used to drive the positioning plate 42 to move up and down. The top of the positioning plate 42 is equipped with a positioning pin 421. The bottom of the pallet 21 is equipped with a positioning hole for inserting into the positioning pin 421. Then, after the pallet 21 reaches the corresponding position, the positioning plate 42 is driven to move up and down, so that the positioning pin 421 is inserted into the positioning hole of the pallet 21, thereby positioning the pallet 21 and the product to be tested on its top.

[0050] Further, please refer to the appendix to the instruction manual. Figure 3 Both the first test chamber 11 and the second test chamber 12 are equipped with interface connection components 14. The interface connection components 14 include docking connectors for plugging into the ports of the product under test, and a drive structure for driving the movement of the above-mentioned structures. For example, a moving plate can be set up, and each connector can be installed on the moving plate. When the tray 21 reaches the designated position and is positioned by the positioning component 4, the moving plate is driven to drive each connector to dock with the port on the product under test to achieve the corresponding electrical connection. For cases with complex port distribution, a robotic arm can be used for automatic operation. Some drive components and cable structures are made of aging-resistant materials (such as polytetrafluoroethylene, fluororubber and carbon fiber composite materials), or a corresponding aging-resistant material protective layer is set to ensure that they can operate stably in the first test chamber 11 and the second test chamber 12.

[0051] In the above embodiments, since the pallet 21 is a reusable moving part, it is not easy to install a drive device that requires energy. Therefore, for the movement drive of the movable frame 51, this embodiment also provides the following technical solution, specifically referring to the appendix to the specification. Figure 6 and Figure 7 The moving drive assembly includes docking frames 53, with multiple sets of docking frames 53. The docking frames 53 are slidably mounted on the positioning plate 42. Movable frames 51 extend downward through the support plate 21. A connector 511 is fixedly connected to the bottom of the movable frame 51. Each docking frame 53 is respectively set corresponding to the movable frame 51. The docking frame 53 is provided with a slot for interlocking with the connector 511. The positioning plate 42 is equipped with a moving drive 54 (such as a linear motor, cylinder, etc.) for driving the docking frames 53 to move. When the positioning plate 42 rises, each docking frame 53 is interlocked with the connector 511. At this time, it can replace the positioning pin 421 to position the support plate 21. Then, the moving drive 54 drives the docking frame 53 to move, which can drive the corresponding movable frame 51 to move. This transfers the drive source to the positioning assembly 4, making it more convenient to provide power. Since there are many movable frames 51, for those with the same direction of movement, a connecting frame can be used to connect the corresponding docking frames 53 and drive them using the same set of moving drives 54.

[0052] In the above embodiment, since the bonding member 52 needs to move continuously relative to the surface of the product to be tested, in order to avoid friction, the movable frame 51 can use a roller bonding member 521. The roller bonding member 521 is rotatably mounted on the movable frame 51, and the circumferential surface of the roller bonding member 521 contacts the surface of the product to be tested. When the movable frame 51 moves, the roller bonding member 521 rolls relative to the surface of the product to be tested, thereby effectively avoiding friction and preventing damage to the surface of the product to be tested.

[0053] However, since the contact between the roller-type bonding component 521 and the product under test is actually a line contact, when the product under test is heavy and the space at the bottom of the product is limited, making it impossible to use a large number of movable local positioning components 5, the single roller-type bonding component 521 located below the product bears a large weight, which may cause extrusion damage to the product surface. Therefore, this embodiment also provides another bonding component 52, as shown in the attached specification. Figure 8In particular, for the bonding component 52 at the bottom of the product under test, the bonding component 52 is a tracked bonding component 522. The tracked bonding component 522 includes multiple track plates 5221, which are hinged in sequence to form a track structure. The tracked bonding component 522 also includes a track frame 5222 and track wheels 5223. The track frame 5222 is fixedly installed on the movable frame 51. Two sets of track wheels 5223 are provided. The track wheels 5223 are rotatably installed on the track frame 5222. The track structure composed of track plates 5221 is fitted on the two sets of track wheels 5223, thereby forming a tracked contact, increasing the contact area between a single bonding component 52 and the product under test. When the bonding component 52 moves, the track structure formed by the track plates 5221 moves on the surface of the product under test, changing the support position. This can also avoid long-term obstruction of the fixed area, and at the same time, it also improves the protection performance of the product.

[0054] In the above embodiments, when the tracked bonding component 522 moves relative to the surface of the product to be tested, each individual track plate 5221 moves in an arc shape on the surface of the track wheel 5223. Therefore, relative displacement may occur during the process of gradually bonding with the product surface. To address this, this embodiment also provides the following solution, as shown in the appendix to the specification. Figure 9 Each track plate 5221 has an anti-friction plate 5224 on its surface. The anti-friction plate 5224 is connected to the track plate 5221 by a movable pin 5225. The track plate 5221 has a circular hole with a diameter larger than that of the movable pin 5225. Under the connection of the movable pin 5225, the anti-friction plate 5224 moves in close contact with the track plate 5221. In actual use, the anti-friction plate 5224 can generate a certain displacement relative to the track plate 5221, and the displacement direction can be multi-directional. As the anti-friction plate 5224 gradually contacts the surface of the product to be tested, it can generate adaptive movement, thereby avoiding minor damage to the surface of the product to be tested.

[0055] It should be noted that the roller-type bonding component 521 and the track-type bonding component 522 provided in this embodiment can also be used in combination. The specific choice can be made freely according to various factors such as the bottom shape of the product on the production line and the bottom space.

[0056] In the above embodiments, since the pallet 21 needs to be reused multiple times, and in actual testing, some defective products inevitably experience aging, i.e., surface structure damage or protective coating peeling off, forming debris that adheres to the surface of the bonding component 52 (both roller-type bonding component 521 and track-type bonding component 522 may adhere to this debris). If not removed in time, during subsequent use, the debris will be squeezed by the bonding component 52 and the product under test, affecting the support accuracy of the product under test, and may also cause squeezing damage to normal products. Therefore, this embodiment also provides the following technical solutions, specifically referring to the appendix to the instruction manual. Figures 6 to 8A nozzle 513 is provided on the top of the movable frame 51 corresponding to the surface of the bonding component 52. An air passage 512 communicating with the nozzle 513 is provided inside the movable frame 51. An air supply system is provided on the positioning plate 42. When the plug 511 is connected to the docking frame 53, the air passage 512 is connected to the air supply system, thereby causing the nozzle 513 to blow air onto the surface of the bonding component 52, so as to blow away the debris generated during the test in time and prevent it from adhering to the bonding component 52 and affecting subsequent tests.

[0057] Furthermore, a protective shell 422 is fixedly installed on the positioning plate 42, and a docking frame 53 is slidably installed on the protective shell 422, with the bottom of the docking frame 53 extending into the protective shell 422. The air supply system includes an air pump 43, which is fixedly installed on the bottom of the positioning plate 42. The suction pipe 431 of the air pump 43 is exposed outside the positioning plate 42, and the blowing pipe 432 of the air pump 43 extends into the protective shell 422. A baffle plate 531 is fixedly connected to the docking frame 53 at the position corresponding to the opening on the protective shell 422. The baffle plate 531 is used to block the opening on the protective shell 422 (the opening is used to accommodate the sliding of the docking frame 53), thereby achieving a relative seal of the protective shell 422. The docking frame 53 is provided with a through hole communicating with the air passage 512, so that air can be blown into the protective shell 422 by the air pump 43 to supply air to each nozzle 513. At the same time, since the suction pipe 431 is exposed... Since the product is exposed to the elements, the air pump 43 supplies ambient air from its vicinity. Therefore, while the nozzle 513 blows air, it can quickly replenish the area between the product and the tray 21 with the surrounding air, thereby making the environment around the product as similar as possible. For example, when the tray 21 enters the high-temperature test chamber for monitoring, the air pump 43 can quickly deliver the surrounding high-temperature gas to the narrow space between the bottom of the product and the tray 21, making the air contacted by the bottom of the product as similar as possible to the overall air supply in the high-temperature test chamber. Especially during the transition from the high-temperature test to the low-temperature test chamber, when the tray 21 moves into the transition zone 13, the air pump 43 supplies air to effectively cool the workpiece and prevent the temperature difference from changing too quickly when the workpiece enters the low-temperature test chamber.

[0058] Meanwhile, each mobile driver 54 is placed in a protective shell 422, which shields the mobile driver 54. Additionally, heat-insulating protective material is provided on the outside of the mobile driver 54 to improve the protection effect.

[0059] Refer to the instruction manual appendix Figure 10 The present invention also provides an online aging test method, comprising the following steps:

[0060] Step 1: Transport the product to be tested from the production line to the idle pallet 21 on the input multi-directional conveyor 32;

[0061] Step 2: The multi-directional conveyor 32 distributes the pallet 21 containing the product to be tested to the idle test conveyor 2, and the test conveyor 2 transports the pallet 21.

[0062] Step 3: The product to be tested is transported to the first test chamber 11 by the test conveyor 2 for high temperature aging test for 30 minutes. During the test, the drive frame 51 and the bonding part 52 move along the surface of the product to be tested, so as to form support and positioning while avoiding long-term blocking of the same area.

[0063] Step 4: Transport the product to be tested to the transition zone 13 via test conveyor 2 and let it stand for 30 minutes;

[0064] Step 5: The product to be tested is transported to the second test chamber 12 via the test conveyor 2 for low-temperature aging test for 30 minutes. During the test, the drive frame 51 and the bonding part 52 move along the surface of their corresponding product to be tested.

[0065] Step 6: The product to be tested, along with the pallet 21, is transported to the multi-directional conveyor 32 at the output end via the test conveyor 2. The tested product is then inspected. If it passes the test, it is transferred to the production line for further processing. If it fails the test, it is transferred to the non-conforming area.

[0066] Step 7: The empty pallet 21 is transported to the pallet lifter 31 at the output end via the multi-directional conveyor 32. The pallet lifter 31 then transports the empty pallet 21 to the return conveyor 22 at the bottom, and then to the pallet lifter 31 at the input end. The pallet lifter 31 at the input end lifts the blank pallet 21 above the multi-directional conveyor 32 at the initial end for cyclic detection.

[0067] In summary, the online aging test equipment provided by this invention provides fully automated online aging testing, reducing handling operations on the production line. It uses a pallet 21 as a carrier for overall aging and testing. The height and length can be customized, and a matching production line can be made. The input and output ends can be equipped with ATE high-voltage and electrical testing equipment and aging carts, allowing ATE testing instruments to be placed on the production line for easy maintenance, reduced footprint, and to replace traditional automated aging methods. This saves on handling labor, ensures smooth product flow on the production line, and improves production efficiency. Furthermore, the pallet 21 can be automatically returned and reused indefinitely within the equipment. The equipment can also employ a motion controller for network cascading. It also allows for precise setting of aging time, charging time, and testing of aging curves.

[0068] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
