Description

Technical Field

[0001] This utility model relates to the technical field of aging test equipment, and in particular discloses an automatic feeding multi-layer aging rack. Background Technology

[0002] Currently, aging tests are generally required for electronic products before they leave the factory to ensure their performance stability and quality reliability. Traditional aging equipment is usually a single-layer structure, requiring frequent manual loading and unloading, occupying a large area, being inefficient, and prone to errors, and cannot meet the needs of rapid aging of large-volume products. Especially in high-capacity factories, problems such as lengthy testing times, uneven aging, and data deviations caused by manual operation seriously restrict production efficiency and quality consistency.

[0003] Furthermore, most existing aging equipment is unidirectional transmission and single-station testing, lacking the ability to automatically lift and connect the aging station, resulting in unstable test contact and affecting test results. To address these issues, there is an urgent need for an aging rack system with a compact structure, capable of multi-layer arrangement, automated feeding, and stable electrical connection capabilities, in order to improve the intelligence and efficiency of aging testing. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an automatic feeding multi-layer aging rack that realizes automatic transmission, positioning, power connection and aging of test workpieces, and supports multi-layer arrangement.

[0005] To achieve the above objectives, this utility model discloses an automatic feeding multi-layer aging rack, comprising a frame and an aging line mounted on the frame. The aging line includes an aging station, an aging fixture, a transmission mechanism, a lifting assembly, and a drive motor. The frame has an interface for electrical connection to an external power source at the aging station. The aging fixture carries the test workpiece and performs aging tests on it. The transmission mechanism, mounted on the frame, transports the aging fixture to the aging station. The output shaft of the drive motor is connected to the transmission mechanism to provide power. The transmission mechanism drives the aging fixture, moving the test workpiece to the aging station. The lifting assembly lifts the aging fixture, detaching it from the transmission mechanism, and allows the test workpiece to electrically connect to the interface for aging testing. This fully automates the entire process from loading the test workpiece to aging and electrical connection testing, significantly reducing manual intervention and improving work efficiency and test consistency. Compared to traditional manual handling and plug-and-play aging methods, this structure integrates transmission, positioning, electrical connection, and testing, improving the automation level and test reliability of the equipment. It is particularly suitable for the rapid aging of large batches of electronic products.

[0006] Specifically, the lifting assembly includes a lifting motor mounted on the frame and a push plate connected to the output shaft of the lifting motor. The lifting motor drives the push plate to push the aging fixture. The aging fixture is smoothly lifted via electric control, ensuring reliable contact with the interface after disconnection from the transmission track and guaranteeing power stability. Traditional methods typically use manual insertion / removal or pneumatic lifting, which suffers from large errors or high maintenance costs. This invention uses a motor-driven lifting method, which offers fast response, high precision, and a compact structure, making it suitable for multi-layer aging environments.

[0007] Specifically, the lifting assembly consists of two sets, located at opposite ends of the aging fixture. This ensures that both ends of the aging fixture are subjected to synchronous force during the lifting process, preventing tilting or skew. It also facilitates stable connection between the electrical port and the power interface. Traditional aging devices often suffer from poor contact or structural misalignment due to single-point lifting, while this design improves lifting balance and connection stability through a dual-point arrangement, making it suitable for precision testing applications.

[0008] Specifically, the aging fixture is equipped with an output port and an input port. The test workpiece is placed on the aging fixture and connected to the output port, while the input port is electrically connected to the interface. This ensures that the test workpiece can be quickly inserted into the fixture to form a complete circuit loop, and also facilitates the quick replacement and maintenance of the electrical fixture. Traditional methods often use separate electrical components, resulting in low workpiece insertion and removal efficiency, numerous contact points, and poor reliability. This structure integrates the input and output ports through an integrated fixture design, achieving standardized connection and strong tooling versatility.

[0009] Specifically, the aging fixture is provided in multiple sets, which are equally spaced along the length of the conveyor mechanism. This allows for parallel aging of multiple workpieces on the same conveyor line, improving the aging capacity per unit time. Unlike the traditional single-station, single-workpiece model, this structure, through modular arrangement, facilitates expansion and maintenance, making it particularly suitable for continuous assembly line operations and improving equipment utilization.

[0010] Specifically, the automatic feeding multi-compartment aging rack also includes control equipment, which is electrically connected to the drive motor, lifting components, and interfaces. This enables unified control of the entire machine, automatically determining the aging process status and precisely executing each action, thus improving automation and intelligence. Compared to traditional decentralized control or manually operated equipment, this control system integrates the automatic coordination of all key action nodes, avoiding errors caused by operational mistakes or information delays, and improving the overall system efficiency.

[0011] Specifically, the aging line is provided in multiple sets, with these sets evenly spaced along the height of the frame. By vertically stacking multiple aging stations, space utilization is effectively improved, achieving more aging treatment channels per unit area. Traditional aging racks are mostly single-layer structures, occupying a large area and having low utilization. This design, through vertical multi-layer arrangement, breaks through the limitations of traditional horizontal layout and significantly improves the aging capacity per unit of equipment.

[0012] Specifically, the aging line also includes a resistor assembly, which comprises a mounting plate mounted on a frame and resistors mounted on the mounting plate. The resistors simulate actual loads, subjecting the test workpiece to realistic working conditions, thereby accurately testing its aging parameters under load. By simulating actual current / voltage load conditions, the aging test more closely resembles real-world operating conditions, improving the reliability and engineering adaptability of the test data. Traditional aging tests only involve powering on the components without considering the impact of load conditions, resulting in low reference value of the test data. This structure introduces resistors to simulate loads, enabling early identification of potential faults such as thermal instability and overload in components, thus optimizing the product selection mechanism.

[0013] Specifically, the automatic feeding multi-layer aging rack also includes a lifting and distributing mechanism. This mechanism comprises a support frame, a conveying assembly, a transmission assembly, and a lifting motor. The lifting motor is mounted on the support frame. The transmission assembly includes a first roller, a second roller, and a transmission belt connecting the first and second rollers. The output shaft of the lifting motor is connected to the first roller. The first and second rollers are located at opposite ends of the support frame and are rotatably connected to it. The transmission belt is connected to the conveying assembly. The lifting motor drives the first roller to rotate, which in turn moves the transmission belt. The moving transmission belt causes the conveying assembly to move closer to or away from the aging line. This design achieves automatic distribution of test workpieces between multiple layers, improving the equipment's flexibility and adapting to the feeding needs of different aging levels. Traditional multi-layer aging devices require manual handling for feeding, which is labor-intensive and inefficient. This design, by integrating a lifting and distributing structure, achieves automatic transfer between different floors, improving the efficiency of upper and lower layer coordination.

[0014] Specifically, the conveying assembly includes a base, a conveyor roller, a conveyor belt, and a conveyor motor. The base is connected to the conveyor belt, the conveyor roller is rotatably connected to the base, the conveyor belt is drive-connected to the conveyor roller, and the output shaft of the conveyor motor is connected to the conveyor roller. The test workpiece is placed on the conveyor belt, and the drive motor drives the conveyor roller to rotate, thereby moving the conveyor belt. The moving conveyor belt transports the test workpiece to the aging line. This achieves automatic conveying of the test workpiece, avoiding manual handling and stacking, improving equipment efficiency, and ensuring the continuity of material flow. Compared to the traditional method of manually moving workpieces up and down, this structure uses an electric drive transmission device combined with a lifting platform to achieve automatic positioning, docking, and material transfer, effectively reducing labor costs and improving equipment continuity and automation.

[0015] The beneficial effects of this utility model are:

[0016] This invention automates the entire process of testing workpieces from loading to aging and electrical connection testing by setting up a lifting component. This significantly reduces manual intervention, improves work efficiency and test consistency. Compared with the traditional manual handling and plug-and-play aging method, this structure integrates transmission, positioning, electrical connection and testing into one, improving the automation level and test reliability of the equipment. It is especially suitable for the rapid aging of large batches of electronic products.

[0017] By vertically stacking multiple aging stations, the space utilization rate is effectively improved, and more aging treatment channels are realized within a unit area. Traditional aging racks are mostly single-layer structures, which occupy a large area and have low utilization rate. This design breaks through the limitations of traditional horizontal layout by vertically arranging multiple layers, which significantly improves the aging capacity of a unit of equipment.

[0018] By setting up a lifting and distributing mechanism, the test workpieces can be automatically distributed between multiple layers, improving the flexibility of the equipment and adapting to the feeding needs of aging stations at different heights. Traditional multi-layer aging devices require manual handling for feeding, which is labor-intensive and inefficient. This design integrates a lifting and distributing structure to achieve automatic transfer between different floors, improving the efficiency of upper and lower layer coordination.

[0027] Please see Figures 1 to 5 As shown, this utility model discloses an automatic feeding multi-layer aging rack, including a frame 1 and an aging line 2 mounted on the frame 1.

The frame 1 has an interface 7 at the aging station that is electrically connected to an external power source. The aging fixture 3 is used to carry the test workpiece and perform aging tests on it. The transmission mechanism 4 is mounted on the frame 1 to transmit the aging fixture 3 to the aging station. The output shaft of the drive motor 6 is connected to the transmission mechanism 4 to provide power to the transmission mechanism 4. The transmission mechanism 4 drives the aging fixture 3 to transport the test workpiece to the aging station. The lifting assembly 5 lifts the aging fixture 3, causing it to detach from the transmission mechanism 4, and the test workpiece is electrically connected to the interface 7 for aging testing. This system automates the entire process of testing workpieces, from loading to aging and electrical connection testing, significantly reducing manual intervention and improving work efficiency and test consistency. Compared to the traditional manual handling and plug-and-play aging method, this structure integrates transmission, positioning, electrical connection, and testing, improving the automation level and test reliability of the equipment. It is particularly suitable for the rapid aging of large batches of electronic products.

[0028] The lifting assembly 5 includes a lifting motor 8 mounted on the frame 1 and a push plate 9 connected to the output shaft of the lifting motor 8. The lifting motor 8 drives the push plate 9 to push the aging fixture 3. The aging fixture 3 is lifted smoothly by electric control, ensuring reliable contact with the interface 7 after disconnection from the transmission track, thus guaranteeing power stability. Traditional methods usually use manual insertion or pneumatic lifting, which have problems such as large errors or high maintenance costs. This utility model adopts a motor-driven lifting method, which has fast response, high precision, and compact structure, and is suitable for multi-layer aging environments.

[0029] The lifting assembly 5 consists of two sets, located at opposite ends of the aging fixture 3. This ensures that both ends of the aging fixture 3 are subjected to synchronous force during the lifting process, preventing tilting or skewness. It also facilitates stable connection between the power connection port and the power interface 7. Traditional aging devices often suffer from poor contact or structural misalignment due to single-point lifting, while this design improves lifting balance and connection stability through a dual-point arrangement, making it suitable for precision testing applications.

[0030] The aging fixture 3 is equipped with an output port 10 and an input port 11. The test workpiece is placed on the aging fixture 3 and connected to the output port 10, while the input port 11 is electrically connected to the interface 7. This ensures that the test workpiece can be quickly inserted into the fixture to form a complete circuit loop, and also facilitates the quick replacement and maintenance of the electrical fixture. Traditional methods often use separate electrical components, which result in low workpiece insertion and removal efficiency, numerous contact points, and poor reliability. This structure integrates the input and output ports through an integrated fixture design, achieving standardized connection and strong tooling versatility.

[0031] The aging fixture 3 is provided in multiple sets, and the multiple sets of aging fixtures 3 are arranged at equal intervals along the length of the conveyor mechanism 4. This allows for parallel aging of multiple workpieces on the same conveyor line, improving the aging processing capacity per unit time. Unlike the traditional single-station, single-workpiece mode, this structure, through modular arrangement, facilitates expansion and maintenance, making it particularly suitable for continuous assembly line operations and improving equipment utilization.

[0032] The automatic feeding multi-compartment aging rack also includes a control device 12, which is electrically connected to the drive motor 6, the lifting component 5, and the interface 7. This enables unified control of the entire machine, automatically determining the aging process status and precisely executing each action, thus improving automation and intelligence. Compared to traditional decentralized control or manually operated equipment, this control system integrates the automatic coordination of all key action nodes, avoiding errors caused by operational mistakes or information delays, and improving the overall system efficiency.

[0033] The aging line 2 is provided in multiple sets, and the multiple sets of aging lines 2 are arranged at equal intervals along the height direction of the frame 1. By vertically stacking multiple aging stations, the space utilization rate is effectively improved, and more aging treatment channels are realized within a unit area. Traditional aging racks are mostly single-layer structures, which occupy a large area and have low utilization rate. This design breaks through the limitations of traditional horizontal layout by vertically arranging multiple layers, which significantly improves the aging capacity of a unit of equipment.

[0034] The aging line 2 also includes a resistor assembly 13, which includes a mounting plate 14 mounted on the frame 1 and resistors 15 mounted on the mounting plate 14. The resistors 15 simulate actual loads, subjecting the test workpiece to real working conditions, thereby accurately testing its aging parameters under load. By simulating actual current / voltage load conditions, the aging test is made closer to actual working conditions, improving the reliability and engineering adaptability of the test data. Traditional aging tests only involve powering on the components without considering the influence of load conditions, resulting in low reference value of the test data. This structure introduces resistors to simulate loads, which can identify potential faults such as thermal instability and overload in components in advance, optimizing the product selection mechanism.

[0035] The automatic feeding multi-layer aging rack also includes a lifting and distributing mechanism 16. The lifting and distributing mechanism 16 includes a support 17, a conveying assembly 18, a transmission assembly 19, and a lifting motor 20. The lifting motor 20 is mounted on the support 17. The transmission assembly 19 includes a first roller 21, a second roller 22, and a transmission belt 23 connecting the first roller 21 and the second roller 22. The output shaft of the lifting motor 20 is connected to the first roller 21. The first roller 21 and the second roller 22 are located at opposite ends of the support 17 and are rotatably connected to the support 17. The transmission belt 23 is connected to the conveying assembly 18. The lifting motor 20 drives the first roller 21 to rotate, causing the transmission belt 23 to move. The moving transmission belt 23 causes the conveying assembly 18 to move closer to or away from the aging line 2. This design achieves automatic distribution of test workpieces between multiple layers, improving the flexibility of the equipment and adapting to the feeding needs of different aging levels. Traditional multi-layer aging devices require manual handling for feeding, which is labor-intensive and inefficient. This design, by integrating a lifting and distributing structure, achieves automatic transfer between different floors, improving the efficiency of upper and lower layer coordination.

[0036] The conveying assembly 18 includes a base 24, a conveyor roller 25, a conveyor belt 26, and a conveyor motor 27. The base 24 is connected to the transmission belt 23, the conveyor roller 25 is rotatably connected to the base 24, the conveyor belt 26 is drive-connected to the conveyor roller 25, and the output shaft of the conveyor motor 27 is connected to the conveyor roller 25. The test workpiece is placed on the conveyor belt 26, and the transmission motor drives the conveyor roller 25 to rotate, thereby moving the conveyor belt 26. The moving conveyor belt 26 transports the test workpiece to the aging line 2. This achieves automatic conveying of the test workpiece, avoiding manual handling and stacking, improving equipment efficiency, and ensuring the continuity of material flow. Compared with the traditional method of manually moving workpieces up and down, this structure uses an electric drive transmission device combined with a lifting platform to achieve automatic positioning, docking, and material flow, effectively reducing labor costs and improving equipment continuity and automation.

[0037] In practice, on the conveyor belt 26 of the conveyor assembly 18, a person or a robot places the workpiece to be tested. The lifting motor 20 starts, driving the transmission belt 23 to lift the conveyor assembly 18 to the target height layer. The conveyor assembly 18 is aligned with the transmission mechanism 4 of the aging line 2 of the target layer to achieve docking preparation. After the lifting mechanism stops, the transmission motor 27 drives the conveyor belt 26 to move and smoothly send the workpiece into the aging fixture 3 of the aging line 2 of that layer. The drive motor 6 starts and controls the aging fixture 3 to move along the transmission mechanism 4 to the preset aging position. After the aging fixture 3 is in place, the lifting motor 8 starts and drives the push plate 9 to push the aging fixture 3 upward. The aging fixture 3 is lifted from the transmission track and electrically connected to the interface 7 provided on the frame 1 to complete the closed-loop power connection. The system starts timing aging. The control device 12 starts the aging process according to the set program and applies voltage, current and simulated load to the workpiece.
