Description

Technical Field

[0001] The present invention relates to the fields of automotive electronics, electronic component aging testing, and in particular to an automotive electronic ECU aging device. Background Art

[0002] As a key component in automobiles, automotive electronic control units (ECUs) must undergo effective testing in simulated real-world environments before leaving the factory. This testing requires powering the product while maintaining high-temperature performance. The previous method, where personnel placed the product in a box-type aging furnace, suffered from limited throughput, time-consuming labor, and low efficiency. Furthermore, this method could not be integrated into production lines, making it difficult to meet growing production capacity demands. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, the present invention aims to solve the problems of backward aging process, low production efficiency and poor reliability of automotive electronic ECUs. By inventing automated equipment, the workload of personnel is reduced, efficiency is improved, and the reliability of product testing is enhanced.

[0004] To achieve the above object, the present invention provides the following technical solutions: This automotive electronic ECU aging equipment primarily consists of an incoming material conveyor, loading and unloading units, a preheating and cooling unit, a high-temperature aging unit, and a discharge conveyor. The incoming material conveyor transports automotive electronic ECUs to be aged; the loading and unloading units handle product loading and unloading; the preheating and cooling units preheat and cool the products; the high-temperature aging unit performs high-temperature aging testing; and the discharge conveyor discharges products that have completed aging testing.

[0005] The high-temperature aging unit includes a aging roller line. This line features a cylinder, balancer, shaft, chain, and conductive rollers. When the cylinder is lifted, the balancer ensures a stable and balanced lift. The shaft rotates, driving the chain and, in turn, the trolley. The conductive rollers maintain contact with the conductive strips at the bottom of the trolley, ensuring continuous power to the trolley.

[0006] More preferably, the loading and unloading unit consists of a trolley and a conveyor roller line. The trolley runs on the conveyor roller line, with operators stationed at the front and rear of the trolley to perform loading and unloading operations. The conveyor roller line provides a track for the trolley, facilitating smooth movement of the trolley within the loading and unloading area, allowing operators to efficiently complete loading and unloading tasks.

[0007] More preferably, the preheating and cooling unit is divided into left and right sides, one side is provided with a mesh channel for preheating the trolley after loading, and the other side is provided with a mesh channel for cooling the products after aging. The mesh channels on both sides are operated independently.

[0008] Furthermore, the preheating and cooling unit is equipped with multiple sets of fans and heating units, which work together to accurately control the furnace temperature in the range of 36-95 degrees, providing a stable and suitable temperature environment for the preheating and cooling process of automotive electronic ECUs.

[0009] Furthermore, the high-temperature aging unit is preferably equipped with a product test control power supply, which continuously supplies power to the automotive electronic ECU on the moving trolley through the circuit on the conveyor roller side. In this way, even when the product is in a moving state during the high-temperature aging process, it can maintain uninterrupted power-on testing, truly recreating the power-on state in actual use scenarios, ensuring that the test results are more reliable and effective. Furthermore, the equipment's circulating roller system is preferably composed of a trolley, a preheating roller line, a cooling roller line, and an aging roller line. This system allows the trolley to circulate between the roller lines, sequentially entering different functional areas such as the preheating and cooling unit and the high-temperature aging unit. This enables the automated flow of automotive electronic ECUs between various testing stages, eliminating the need for frequent manual intervention and significantly improving the consistency and production efficiency of the aging test process.

[0010] Further optimization, the cylinder is responsible for the jacking action. During its operation, the balancer works closely with it to ensure that the trolley always remains stable when rising and falling, avoiding tilting, shaking, etc., providing reliable guarantee for the stable operation of the trolley on the aging roller line.

[0011] Furthermore, the rotation of the shaft drives the chain, which in turn drives the trolley to move smoothly on the aging roller line. At the same time, the conductive roller always maintains contact with the conductive strip at the bottom of the trolley, ensuring that the trolley is continuously powered during the entire movement process, providing stable power supply conditions for product aging testing and meeting the requirements for product power supply status during testing.

[0012] Furthermore, the high-temperature aging unit preferably includes an aging furnace body with a rolling shutter door on the outside. During the high-temperature aging test of the automotive electronic ECU, the rolling shutter door is closed, thereby effectively isolating the high-temperature environment inside the furnace from the outside world, reducing heat loss, maintaining a stable temperature inside the furnace, and providing stable high-temperature aging test conditions for the product.

[0013] The present invention has the following beneficial effects: The present invention uses a circulating line composed of a circulating roller and a chain line to realize the automatic flow of automotive electronic ECUs between various test units, without the need for frequent manual handling. Compared with the original operation method of manually placing them into a box-type aging furnace, more products can be processed at a time and the operating time of personnel is reduced. It can be effectively embedded in the production line to achieve uninterrupted operation, greatly improving production efficiency and meeting the growing production capacity demand.

[0014] The present invention adopts an automated loading and unloading and cyclic testing process, which reduces the frequency of manual handling and operation. Operators only need to perform loading and unloading operations at fixed positions, which reduces labor intensity and also reduces the error rate caused by manual operation fatigue; through the independent circulation preheating and cooling units, the preheating and cooling parameters can be accurately controlled respectively to ensure the performance stability of the product before and after testing; the high-temperature aging unit can accurately control the furnace temperature in the range of 36-95 degrees, and ensure that the product is tested without interruption during the movement process, truly simulating the actual use environment, comprehensively testing product performance, effectively improving the reliability and accuracy of product testing, and thus improving the product quality of automotive electronic ECUs.

[0022] The present invention will be further described below with reference to the accompanying drawings and related knowledge, and described clearly and completely. Obviously, the described applications are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figures 1-6 As shown, an automotive electronic ECU aging device of the present invention is mainly composed of an incoming material conveyor belt 100, a loading and unloading unit 200, a preheating and cooling unit 300, a high-temperature aging unit 400, and a unloading material conveyor belt 500.

[0024] Incoming material conveyor belt 100: Its function is to convey the automotive electronic ECU to be tested for aging to the loading and unloading unit 200 of the equipment, playing the role of material input and providing initial materials for the subsequent aging test process.

[0025] The loading and unloading unit 200 comprises a trolley 201 and a conveying roller line 203. The trolley 201 moves on the conveying roller line 203, with two operators positioned at the front and rear of the trolley to perform loading and unloading operations. This design allows operators to efficiently load and unload materials from a relatively fixed position, reducing time wasted by moving around and carrying materials over long distances. This improves loading and unloading efficiency and ensures material stability and accuracy during the loading and unloading process.

[0026] Preheating and Cooling Unit 300: This unit is divided into two sides. One side features a preheating mesh 301 for preheating the loading trolley; the other side features a cooling mesh 301 for cooling products after high-temperature aging. Each mesh 301 operates independently. This independent circulation design allows precise control of preheating and cooling process parameters such as temperature, time, and air speed, preventing interference between the preheating and cooling processes. This provides a stable and reliable preheating and cooling environment for the product, improving product performance stability and the accuracy of test results across different testing stages. Multiple Fans 305 and Heating Units 306: The furnace body is composed of multiple fans and heating units. By precisely adjusting the fan speed and heating unit power, the furnace temperature can be stably controlled within a range of 36-95 degrees Celsius. This simulates the high-temperature environments that automotive electronic ECUs may encounter under different actual operating conditions, allowing for comprehensive testing of product performance and reliability under varying temperature conditions.

[0027] High-temperature aging unit 400: aging roller line 402 and aging furnace body 403: The aging furnace body is provided with a rolling shutter door 401. During the high-temperature aging process, the rolling shutter door is closed to isolate the high-temperature environment in the furnace from the outside world, reduce heat loss, maintain the temperature in the furnace stable, and ensure that the product is aged in a stable high-temperature environment; the rolling shutter door is opened only when the trolley enters and exits the aging furnace body, so that the trolley can smoothly enter and exit the aging furnace body, and realize the automatic cycle test of the product in the aging furnace body.

[0028] Product test control power supply 404: The product test control power supply 404 supplies power to the automotive electronic ECU on the moving trolley through the circuit on the conveyor roller side, ensuring that the product is continuously powered on during the high-temperature aging test, truly simulating the power-on state of the product in actual use, so that the test results can better reflect the performance of the product under actual working conditions, and improve the reliability and effectiveness of the test results.

[0029] Unloading conveyor belt 500: Its function is to convey the products that have completed the aging test out of the equipment for subsequent quality inspection, packaging and other processes, so as to achieve smooth output of the products after the aging test.

[0030] The circulating drum process of the present invention is as follows: the circulating drum is composed of a trolley 201, a preheating drum line 302, a cooling drum line 303, and an aging drum line 402. Its working process is as follows: after the trolley 201 completes loading and unloading on the transporting drum line 203, it enters the preheating drum line 302 for preheating. After preheating is completed, it enters the aging drum line 402 to perform a high-temperature aging test in the high-temperature aging unit 400. After the aging test is completed, it enters the cooling drum line 303 for cooling, and finally unloads the material through the unloading conveyor belt 500. Through this cyclic transportation method, the trolley can enter each unit in turn to perform the corresponding test, realizing an automated cyclic process for automotive electronic ECU aging testing, eliminating the need for frequent manual handling, improving production efficiency, and ensuring the consistency and stability of the testing process.

[0031] The operating principle of the burn-in roller line 402 of the present invention is as follows: Burn-in roller line 402 comprises a cylinder 40203, a balancer 40201, a shaft 40204, a chain 40202, and a conductive roller 40205. When cylinder 40203 is lifted, balancer 40201 effectively ensures balanced lifting, preventing the trolley from tilting during the lifting process and ensuring smooth ascent and descent of the trolley. Shaft 40204 rotates, driving chain 40202, which in turn drives the trolley to translate, achieving smooth movement of the trolley on the burn-in roller line. Conductive roller 40205 maintains contact with the conductive strips underneath the trolley, ensuring that the trolley remains energized during movement, meeting the power requirements of product burn-in testing and ensuring that product performance can be continuously tested during the burn-in test.

[0032] In the present invention, the circulating roller structure realizes the automatic circulation of the trolley in each unit, with a high degree of automation. The unique components of the aging roller line cooperate to ensure the smooth movement of the trolley and continuous power supply, ensuring the smooth progress of the aging test. The overall equipment solves the problems of low efficiency and poor reliability of traditional aging tests through the coordination of various parts. The present invention utilizes circulating rollers and chain lines to form a circulating line body. The product is placed on the trolley, passes through the loading area and preheating area, and arrives at the aging area for high-temperature aging. After completion, it passes through the cooling area and unloading area for unloading. It can be effectively embedded in the production line to achieve uninterrupted operation, improve production efficiency, and ensure reliability.

[0033] Example 1, an automotive electronic ECU aging device, consists of an incoming material conveyor belt 100, a loading and unloading unit 200, a preheating and cooling unit 300, a high-temperature aging unit 400, a discharge material conveyor belt 500, etc.

[0034] The loading and unloading unit 200, the trolley 201 moves on the conveying roller line 203, and two operators are respectively responsible for loading and unloading on the front and back sides.

[0035] The preheating and cooling unit 300 is divided into two sides, one for preheating the loaded trolley and the other for cooling the aged products. Each side has an independent network channel 301 for circulation.

[0036] In the aging unit 400, a trolley moves on an aging roller line 402. The aging furnace is equipped with a rolling shutter 401, which closes during the high-temperature aging process and opens only when the trolley enters or exits. The furnace is equipped with multiple fans and heating units to control the temperature between 36 and 95 degrees Celsius. The product test control power supply 404 is supplied to the moving trolley via a circuit on the conveyor roller side, ensuring uninterrupted power during testing.

[0037] The circulating roller chain motion unit is composed of a trolley 201, a preheating roller line 302, a cooling roller line 303, an aging roller chain line 402, etc. The trolley can be circulated to enter each unit for corresponding testing.

[0038] The aging roller line 402 is provided with a lifting and transverse movement unit. Specifically, when the cylinder 4023 is lifted, the balancer 40201 can effectively ensure the lifting balance, the shaft 40204 rotates, driving the chain 40202 to rotate, driving the trolley to move horizontally, and the conductive roller 40205 can always contact the conductive bar under the trolley to ensure that the trolley is always powered.

[0039] This invention overcomes the limitations of traditional box-type aging furnaces, which have limited single operations and high labor reliance, by creatively employing circulating rollers and chain lines to construct a circulating line. By organically integrating the trolley with the incoming material conveyor, loading and unloading units, preheating and cooling units, high-temperature aging units, and unloading conveyor, it achieves a fully automated cycle for the entire automotive electronic ECU process, from feeding, preheating, high-temperature aging, cooling, to discharging.

[0040] The efficient loading and unloading unit features an innovative layout: In the loading and unloading unit, a trolley moves along a conveyor roller line, with operators positioned at the front and rear of the trolley to perform loading and unloading. This layout reduces unnecessary movement for operators, making loading and unloading operations more compact and efficient. Compared to traditional single-operator or random layout methods, it significantly shortens loading and unloading times and improves overall production cycle time.

[0041] The preheating and cooling units feature independent circulation innovations: The preheating and cooling units utilize a mesh design with independent circulation channels on both sides, with one side responsible for preheating and the other for cooling. This independent circulation system allows for precise control of parameters such as temperature, time, and air speed during both the preheating and cooling processes, preventing cross-process interference. This provides a more stable and practical pre- and post-processing environment for the product, significantly improving performance stability before and after testing.

[0042] Intelligent temperature control and power supply of the high-temperature aging unit: The aging furnace is equipped with a rolling shutter door, which is closed during the high-temperature aging process and only opened when the trolley is entering or exiting, effectively reducing heat loss and maintaining a stable temperature in the furnace; multiple sets of fans and heating units work together to achieve precise temperature control in the range of 36-95 degrees, which can simulate a variety of complex actual working conditions; the product test control power supply continuously supplies power to the ECU on the moving trolley through the conveyor roller side circuit, so that the product remains in a powered test state during the dynamic aging process, truly restoring the actual usage scenario, which is difficult to achieve in traditional aging equipment.

[0043] The aging roller line features precise transmission and power supply: The aging roller line utilizes a combination of cylinders, balancers, shafts, chains, and conductive rollers. The balancer ensures balanced lifting during cylinder lifting, preventing the trolley from tilting. The shaft and chain transmission structure ensures smooth translation of the trolley. The conductive rollers maintain constant contact with the trolley's conductive strips, ensuring the trolley remains powered throughout its motion. This solves the challenges of unstable power supply and transmission in traditional equipment, providing reliable support for precise aging testing.

[0044] The technical principles of the present invention have been described above in conjunction with specific embodiments, which are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention fall within the scope of protection of the present invention. Those skilled in the art will be able to conceive of other specific embodiments of the present invention without inventive effort, and such methods will fall within the scope of protection of the present invention.
