Description

Technical Field

[0001] This utility model relates to the field of automated testing technology, specifically to an island-type automatic aging device. Background Technology

[0002] In the manufacturing of electronic components and modules (especially power-load products such as high-power power modules and core components of charging piles), aging testing is a critical process to ensure product reliability. It involves simulating long-term operating environments to screen for products that fail early. The efficiency of the material handling process and the connection between the testing phase directly affects the capacity and stability of the entire production line. Currently, in the industry, for aging testing of power-load products, manual wiring is a necessary operation in the existing production model because the products need to be electrically connected to the testing system. However, existing aging testing equipment and related technologies have significant limitations in integrating material handling functions and ensuring seamless process connection after wiring, making it difficult to improve overall efficiency.

[0003] The structural characteristics of the source carrier product dictate that it needs to be equipped with multiple power connection ports (including main power interface, signal feedback interface, communication interface, etc.), and the positions are not on the same side. Automated production cannot achieve direct automated docking between the source carrier product and the aging test storage location through a stacker crane. It is necessary to first electrically connect the source carrier product to the sub-fixture corresponding to the aging test storage location, and then achieve automated docking with the aging storage location through the sub-fixture.

[0004] While manual wiring is a necessary step, existing aging test equipment lacks an integrated loading and unloading solution adapted to this operation. On the one hand, the loading and unloading stations are independent of the aging test chamber. Operators must complete the wiring of the source product and sub-rig in a separate loading area, and then manually move the sub-rig with the product to the entrance of the aging test chamber. After testing, the sub-rig must be moved from the chamber exit to a separate unloading area for disconnection and product unloading. Throughout the process, the transfer of sub-rigs relies entirely on manual labor, which is not only labor-intensive but also difficult to match with the testing efficiency of the aging test chamber. This can easily lead to a backlog of sub-rigs waiting to be tested at the chamber entrance or a delay at the exit, creating a bottleneck between processes. On the other hand, existing equipment does not have a unified conveying mechanism connecting the loading and unloading stations and the aging test chamber. Sub-rigs cannot be automatically transferred, and there are risks of sub-rig collisions and positional shifts during manual transfer, which may affect the accurate docking with the test chamber and increase test preparation time.

[0005] The applicant's previously published patent (publication number: CN223495357U), "A Double-Sided Testing Machine," while solving the problem of transfer efficiency during double-sided product testing through the collaborative design of dual test lines and dual robotic arms, and achieving efficient posture switching and transport of the product to be tested between different test sections, focuses its core design on "parallelization of the testing process and transfer of the product within the testing section," without integrating the loading and unloading stations with the testing process. The loading and unloading operations of this patent still need to be independent of the testing and conveying system. It lacks dedicated loading and unloading stations adapted for manual wiring of the source product, and also lacks a conveying mechanism that can drive the transfer of sub-fixtures, making it impossible to achieve a seamless process of "loading and wiring - testing - unloading and disconnecting." When dealing with source products requiring manual wiring, the automated conveying advantage of this double-sided testing machine cannot extend to the loading and unloading stages, still requiring manual transfer of sub-fixtures, resulting in a break in the overall automation level of the process and failing to fully utilize the equipment's testing efficiency.

[0006] Further analysis of existing technologies reveals that while some aging test equipment attempts to set up simple loading and unloading areas, it fails to form a closed-loop layout of "loading station - conveyor mechanism - aging test chamber - unloading station." The movement of sub-fixtures between loading / unloading and the test chamber still requires manual intervention, and empty fixtures cannot be automatically returned to the loading station. Operators must manually retrieve and organize them before reuse, further increasing manual labor and process time. In mass production scenarios, this decentralized, manually dependent loading and unloading mode not only slows down the overall production pace but also makes the process stability susceptible to the randomness of manual operations, failing to meet the demands of large-scale production for efficient and orderly aging testing.

[0007] In summary, existing technologies for aging tests of source-load products requiring manual wiring suffer from several problems: dispersed loading / unloading stations and test chambers lack integrated layout; and the applicant's existing double-sided testing machine does not cover the loading / unloading process and cannot automate the transfer of sub-fixtures. Therefore, there is an urgent need for an aging test device that integrates loading / unloading stations and a conveying mechanism to achieve efficient connection between the sub-fixtures and the aging test chamber after manual wiring, while simultaneously enabling automatic return of empty fixtures, thus overcoming the efficiency bottleneck of the current dispersed loading / unloading process and reliance on manual transfer.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-8 In this embodiment of the utility model, an island-type automatic aging device is described: I. Overall Equipment Structure This utility model discloses an island-type automatic aging device, which consists of two core parts: a loading / unloading platform 10 and an aging test chamber 80. Through integrated design, it achieves a closed-loop process of "loading and wiring - testing - unloading and disconnecting - empty fixture return". The loading / unloading platform 10, as the core of the integrated system, integrates a conveyor mechanism 30, a loading station 40, and an unloading station 50. These three work together to complete the conveying of the workpiece to be tested, the retrieval of the test workpiece, and the recycling of the empty fixture. The aging test chamber 80 can adopt the test chamber form of the applicant's previous patent (such as CN223495357U double-sided testing machine, or a similar multi-layer three-dimensional storage structure). It has multiple testing stations inside to simulate the long-term working environment of the source product. After receiving the workpiece to be tested from the conveyor mechanism 30 and completing the test, it returns the workpiece to the conveyor mechanism 30, thus forming an island-type testing process.

[0025] II. Configuration of Conveying Mechanism 30 and Fixture Plate 20 The conveying mechanism 30 is the key carrier for realizing the workpiece flow. It is equipped with several fixture plates 20 (i.e., sub-fixtures mentioned in the background art) that can move along the conveying direction. The structure of the fixture plates 20 is adapted to the shape and power connection requirements of the source carrier products (such as high-power power modules, core components of charging piles, etc.) to stably support the workpieces to be tested or the workpieces that have completed testing. Driven by the power of the conveying mechanism 30, the fixture plates 20 can achieve multi-path movement: accurately conveying the workpieces to be tested that have been wired at the loading station 40 to the entrance of the aging test chamber 80; after the test is completed, the fixture plate 20 carrying the tested workpieces is conveyed from the exit of the aging test chamber 80 to the unloading station 50; after the workpieces are unwired and unloaded, the conveying mechanism 30 continues to drive the empty fixture plates 20 back to the loading station 40, completing the recycling of the fixture plates 20 without the need for manual intervention in the recovery and transfer of empty fixtures.

[0026] III. Specific Structure of Loading and Unloading Platform 10 The loading and unloading platform 10 includes a counter 101, and the conveying mechanism 30 forms a roughly island-shaped layout based on the counter 101. Specifically, it consists of an infeed X-axis conveyor line 301, an outfeed X-axis conveyor line 302, and a Y-axis conveyor line 303. The infeed X-axis conveyor line 301 is located on one side of the counter 101, with one end connected to the entrance of the aging test chamber 80 and the other end connected to one end of the Y-axis conveyor line 303. The outfeed X-axis conveyor line 302 is located on the other side of the counter 101, with one end connected to the exit of the aging test chamber 80 and the other end connected to the other end of the Y-axis conveyor line 303, forming a complete closed-loop conveying path. Meanwhile, the feeding X-axis conveyor line 301 integrates an electrical testing assembly 3011, which is used to perform pre-detection of electrical connections before the workpiece enters the aging test chamber 80 to ensure the accuracy of the test; the discharging X-axis conveyor line 302 integrates an elevator assembly 3021, which is used to adapt to the conveying of workpieces at different heights in the aging test chamber 80, and to achieve the height connection of the fixture plate 20 between the conveyor line and the test chamber.

[0027] The Y-axis conveyor line 303 serves as a crucial channel connecting the infeed X-axis conveyor line 301 and the discharge X-axis conveyor line 302. Along its conveying direction, it is sequentially equipped with a discharge station 50 and a loading station 40, and a discharge conveyor station 60 is located at the junction of the Y-axis conveyor line 303 and the discharge X-axis conveyor line 302. To optimize throughput efficiency, the Y-axis conveyor line 303 is further divided into a first Y-axis conveyor branch line 3031 and a second Y-axis conveyor branch line 3032. The first Y-axis conveyor branch line 3031 corresponds to the infeed X-axis conveyor line 301, and the loading station 40 is located on this branch line. The second Y-axis conveyor branch line 3032 corresponds to the discharge X-axis conveyor line 302, and both the discharge conveyor station 60 and the discharge station 50 are located on this branch line. This branch line design achieves spatial separation between the loading and unloading processes, preventing interference between the fixture plate 20 and the loading / unloading process due to path intersections.

[0028] IV. Detailed Structure of Loading Station 40 The loading station 40 includes a first loading lifting station 401 and a second loading lifting station 402, both of which are installed on the conveying frame of the Y-axis conveyor line 303 to carry the jig plate 20 (sub-jig). By lifting, the jig plate 20 is relatively isolated, making it easier for operators to perform wiring operations on the source product.

[0029] 1) First loading and lifting station 401: It is set at the junction of Y-axis conveyor line 303 and feeding X-axis conveyor line 301. Its structure includes first fixed seat 4011, first X-axis synchronous belt lifting mechanism 4012 and first loading and lifting mechanism 4013. The first fixed base 4011 is fixedly connected to the conveyor frame of the Y-axis conveyor line 303, providing the installation foundation for the entire mechanism. The first X-axis synchronous belt lifting mechanism 4012 is installed on the first fixed base 4011, specifically composed of a first lifting cylinder 40121, a first movable plate 40122, and a first X-axis synchronous belt assembly 40123. The first lifting cylinder 40121 is poweredly connected to the first fixed base 4011, that is, the movable end of the first lifting cylinder 40121 is connected to the first fixed base 4011 and can move relative to the first fixed base 4011. The first movable plate 40122 is fixedly connected to the first lifting cylinder 40121, that is, the first movable plate 40122 is fixedly connected to the body of the first lifting cylinder 40121 and can move with the first lifting cylinder 40121. The first X-axis synchronous belt assembly 40123 is installed on... On the first movable plate 40122, driven by the extension and retraction of the first lifting cylinder 40121, the first X-axis synchronous belt lifting mechanism 4012 can move up and down relative to the first fixed seat 4011 to achieve high docking with the feeding X-axis conveyor line 301; the first loading lifting mechanism 4013 is installed on the first X-axis synchronous belt lifting mechanism 4012, including a second lifting cylinder 40131 fixedly connected to the first movable plate 40122, and a first loading connecting plate 40132 poweredly connected to the movable end of the second lifting cylinder 40131. The first loading connecting plate 40132 is used to support the fixture plate 20. By extending and retracting the second lifting cylinder 40131, the fixture plate 20 can be moved up and down, making the fixture plate 20 relatively isolated, which makes it convenient for the operator to place the workpiece to be tested on the fixture plate 20 and complete the wiring operation of each electrical port.

[0030] 2) Second loading and lifting station 402: Located on the side of the first loading and lifting station 401 near the unloading station 50, its structure includes a fourth fixed base 4021, a sixth lifting cylinder 4022, and a second loading connecting plate 4023. The fourth fixed base 4021 is fixedly connected to the conveying frame of the Y-axis conveyor line 303, the sixth lifting cylinder 4022 is fixedly connected to the fourth fixed base 4021, and the second loading connecting plate 4023 is poweredly connected to the movable end of the sixth lifting cylinder 4022, used to support the empty jig plate 20 or the jig plate 20 to be wired. The height of the jig plate 20 is adjusted by the extension and retraction of the sixth lifting cylinder 4022, making the jig plate 20 relatively isolated, providing a comfortable wiring operation height for the operator, and realizing the temporary storage and transfer connection of the jig plate 20 on the Y-axis conveyor line 303.

[0031] Furthermore, considering that the wiring of the source product requires connection to multiple power ports in different locations, the operation process is complex and time-consuming, while the unloading and wire disconnection only requires disconnecting the existing connection, which is simpler and less time-consuming. There is a significant efficiency difference between the two. Moreover, the empty fixture plate 20 after unloading needs to be returned to the loading end for recycling. Therefore, a second loading lifting station 402 is set up with a corresponding buffer conveyor section 70 (no lifting required, only used for buffering the flow of fixture plate 20): After the empty fixture plate 20 is disconnected in the unloading process, it is directly conveyed to the buffer conveyor section 70 through the conveyor mechanism 30. The material is temporarily stored at section 70 and then transferred to the second loading and lifting station 402. Operators can then perform wiring operations on the fixture plates 20 at the second loading and lifting station 402 and the first loading and lifting station 401 (i.e., disconnecting wires at one station and wiring at both stations). This eliminates the need to wait for the empty fixture plates 20 to return, avoids supply interruptions at the loading end due to long wiring times, and allows the return of empty fixture plates 20 and the loading wiring to form a parallel process, ensuring the continuity of the loading process. This, in turn, matches the testing efficiency of the aging test chamber 80 and improves the overall production line turnover rate.

[0032] V. Detailed Structure of Material Cutting Stations (a) Material unloading station 50 The unloading station 50 is installed on the conveyor frame of the Y-axis conveyor line 303. Its structure includes a third fixed base 501 and a second unloading lifting mechanism 502. The third fixed base 501 is fixedly connected to the conveyor frame of the Y-axis conveyor line 303. The second unloading lifting mechanism 502 includes a fifth lifting cylinder 5021 fixedly connected to the third fixed base 501, and a second unloading connecting plate 5022 powered by the fifth lifting cylinder 5021. The second unloading connecting plate 5022 is used to carry the fixture plate 20 (sub-fixture) corresponding to the workpiece after testing. Through the extension and retraction drive of the fifth lifting cylinder 5021, the second unloading connecting plate 5022 can drive the fixture plate 20 to move up and down, making the fixture plate 20 relatively isolated, which facilitates the operator to perform wire disconnection and workpiece unloading operations. The empty fixture plate 20 after unloading remains on the second unloading connecting plate 5022, waiting for the conveyor mechanism 30 to drive it back to the loading station 40.

[0033] (ii) Material unloading and conveying station 60 The unloading conveying station 60 is located at the junction of the Y-axis conveyor line 303 and the discharge X-axis conveyor line 302, and is located on the side of the unloading station 50 away from the loading station 40. Its structure includes a second fixed base 601, a second X-axis synchronous belt lifting mechanism 602, a first unloading lifting mechanism 603, and a rotating mechanism 604.

[0034] The second X-axis synchronous belt lifting mechanism 602 is mounted on the second fixed base 601 and consists of a third lifting cylinder 6021, a second movable plate 6022, and a second X-axis synchronous belt assembly 6023. The third lifting cylinder 6021 is poweredly connected to the second fixed base 601, meaning its movable end is connected to the second fixed base 601 and can move relative to it. The second movable plate 6022 is fixedly connected to the third lifting cylinder 6021, meaning it is fixedly connected to the main body of the third lifting cylinder 6021 and can move with it. The second X-axis synchronous belt assembly 6023 is mounted on the second movable plate 6022. This mechanism can drive the first unloading lifting mechanism 603 and the rotating mechanism 604 to lift or lower together, achieving a high-level connection with the discharge X-axis conveyor line 302.

[0035] The first unloading lifting mechanism 603 is mounted on the second X-axis synchronous belt lifting mechanism 602. It includes a fourth lifting cylinder 6031 fixedly connected to the second movable plate 6022, and a first unloading connecting plate 6032 powered by the fourth lifting cylinder 6031. This mechanism can be raised and lowered under the drive of the second X-axis synchronous belt lifting mechanism 602, and can also drive the rotating mechanism 604 to lift itself.

[0036] Rotating mechanism 604: Installed on the first unloading lifting mechanism 603, it consists of a driving component 6041 (such as a servo motor) fixedly connected to the second movable plate 6022 and a rotating plate 6042 rotatably connected to the first unloading connecting plate 6032. The rotating plate 6042 is poweredly connected to the driving component 6041 and is used to support the fixture plate 20. When the workpiece that has completed the test is conveyed to the unloading conveyor station 60 along with the fixture plate 20, the second X-axis synchronous belt lifting mechanism 602 first drives the first unloading lifting mechanism 603 and the rotating mechanism 604 to rise and fall together to connect with the unloading X-axis conveyor line 302. Then, the first unloading lifting mechanism 603 drives the first unloading connecting plate 6032 to rise, causing the fixture plate 20 to detach from the conveying surface of the Y-axis conveyor line 303, making the fixture plate 20 relatively isolated. After that, the driving component 6041 drives the rotating plate 6042 to rotate, realizing the adjustment of the direction of the fixture plate 20 to adapt to the operating angle of the unloading station 50 or the direction requirement of the empty fixture plate 20 returning. After the adjustment is completed, the first unloading lifting mechanism 603 and the second X-axis synchronous belt lifting mechanism 602 are reset in sequence, and the fixture plate 20 falls back to the conveyor mechanism 30 to continue to flow.

[0037] VI. Equipment Workflow Description The aging test process for the workpiece to be tested is as follows: First, the empty fixture plate 20 is returned to the second loading and lifting station 402 or the first loading and lifting station 401 via the conveying mechanism 30. The lifting mechanism isolates the fixture plate 20. The operator places the workpiece to be tested on the fixture plate 20 and completes the wiring operations of each power connection port. After the wiring is completed, the conveying mechanism 30 moves the fixture plate 20 carrying the workpiece to be tested along the Y-axis conveying line 303 to the first loading and lifting station 401. The first X-axis synchronous belt lifting mechanism 4012 adjusts the height so that the fixture plate 20 is connected to the feeding X-axis conveying line 301. Then, the fixture plate 20 enters the aging test chamber 80 via the feeding X-axis conveying line 301. After the pre-test is completed by the power-on test assembly 3011, the workpiece undergoes aging test in the chamber. After the test is completed... The fixture plate 20, carrying the tested workpiece, is moved out of the aging test chamber 80 and transported to the unloading conveyor station 60 via the discharge X-axis conveyor line 302. The lifting assembly 3021 completes the height adaptation. The second X-axis synchronous belt lifting mechanism 602 drives the first unloading lifting mechanism 603 and the rotating mechanism 604 to lift and connect. The first unloading lifting mechanism 603 lifts the fixture plate 20 to isolate it relatively, and the rotating mechanism 604 adjusts the direction of the fixture plate 20 as needed. Then, the conveying mechanism 30 drives the fixture plate 20 to move along the Y-axis conveyor line 303 to the unloading station 50. The second unloading lifting mechanism 502 lifts the fixture plate 20 to isolate it relatively, and the operator performs wire disconnection and workpiece unloading. After unloading, the empty fixture plate 20 is returned to the loading station 40 via the Y-axis conveyor line 303 to enter the next cycle. Throughout the entire process, the jig plate 20 is driven by the conveying mechanism 30, eliminating the need for manual handling and achieving efficient connection between loading / unloading and testing.

[0038] In summary, this utility model integrates the loading and unloading platform 10 with the aging test chamber 80 to construct a closed-loop layout of "loading station 40 - conveying mechanism 30 - aging test chamber 80 - unloading station 50". It achieves automated flow of fixture plate 20 by means of island conveying, eliminating the manual transfer of sub-fixtures, reducing labor intensity and the risk of collision and displacement, and ensuring accurate docking with the test chamber. At the same time, it realizes automatic return and reuse of empty fixture plate 20, effectively solving the bottleneck of waiting between processes, improving the automation level and flow efficiency of the overall process, and meeting the needs of large-scale production for efficient and orderly aging testing.
