Description

Technical Field

[0001] This utility model relates to the field of aging test cabinets, specifically a pressure-resistant aging test cabinet. Background Technology

[0002] An aging test cabinet (also known as an aging chamber or burn-in cabinet) is a device that simulates the aging process of a product under long-term use or specific environmental conditions by controlling environmental factors such as temperature, humidity, light, and gas composition to evaluate its performance and lifespan. The aging test cabinet improves product reliability by removing defective components through burn-in. It shortens the testing cycle by simulating extreme environments such as high temperature, low temperature, high humidity, low humidity, and ultraviolet radiation. It can measure changes in product parameters during the aging process, such as lifespan, capacity decay, and internal resistance changes. Its working principle is as follows: Environmental Simulation: Temperature, humidity, and light conditions inside the cabinet are precisely controlled through a heating system, humidification / dehumidification device, and ultraviolet light source. Charge / Discharge Cycles: Batteries and other products are subjected to cyclic charging and discharging to simulate changes in electrical performance during actual use. Data Acquisition: Environmental parameters (such as temperature and humidity) and product performance data are monitored and recorded in real time for subsequent analysis. It is mainly used to test the weather resistance and stability of electronic components, circuit boards, and integrated circuits. It is also used to evaluate the performance of consumer electronics products such as mobile phones and computers under extreme environments.

[0003] Traditional aging test cabinets typically employ a fixed sample rack structure, testing samples through static placement. These devices generally suffer from two major technical bottlenecks: First, sample transport relies heavily on manual loading of each sample, hindering continuous testing processes, resulting in low efficiency and the risk of human error. Second, existing technologies utilize conveyor belt structures with fixed spacing. When dealing with samples of different sizes, frequent changes to the internal conveyor mechanism or the use of different aging test cabinet sizes for single testing are necessary. When transporting small samples, they are prone to falling and accumulating inside the cabinet, or getting stuck in the gaps of the conveyor belt, causing jams or transport failures and frequent shutdowns. Conversely, when transporting large samples, the fixed spacing of the conveyor belt prevents adjustment of the belt spacing, hindering the transport of large samples. Therefore, these aging test cabinets cannot adapt to different sample sizes, cannot quickly adjust the testing distance to accommodate different sizes, and are inconvenient for continuous, offset-free sample transport, resulting in poor equipment flexibility.

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.

[0021] The following is combined Figures 1-4 A detailed description of a pressure aging test cabinet according to this utility model is provided below:

[0022] A pressure aging test cabinet includes a body 1, inside which a pressure testing assembly 2 and a conveying assembly are arranged. A control panel 8 is arranged on the surface of the body 1, and a partition 12 is arranged inside the body 1. The conveying assembly includes several fixed seats 16 fixedly mounted on the surface of the partition 12, two guide rails 9, a conveyor belt 26 disposed inside the guide rails 9, and a rotating motor 20. A base plate 17 is arranged between two adjacent fixed seats 16. Two side plates 18 are arranged on the top of the base plate 17, and a slide rail 14 is arranged between the two side plates 18. One end of the slide rail 14 is fitted with a rotatable thread. The lead screw 15 has both ends passing through the side plate 18 and being rotatably connected to the side plate 18. One end of the lead screw 15 is provided with a fixed tooth 21, and a chain 13 is provided between adjacent fixed teeth 21. Adjacent fixed teeth 21 are connected by the chain 13. The bottom of the guide rail 9 extends outward to form a limiting part 23. The limiting part 23 is fitted with a rotating roller 22. Both ends of the rotating roller 22 pass through the limiting part 23 and are rotatably connected to the limiting part 23. Several fixed rollers 25 are provided inside both guide rails 9. The several fixed rollers 25 are connected by a conveyor belt 26.

[0023] The machine body 1 is also provided with a cabinet 34, the surface of which is provided with double doors 3 and handles 4. The surface of the double doors 3 is also provided with a flip-up cover 5, the surface of which is provided with a U-shaped handle 6. The surface of the partition 12 is provided with several fastening seats. The two ends of the rotating roller 22 pass through the fastening seats and are rotatably connected to the fastening seats. A connecting belt 19 is provided between the rotating motor 20 and the rotating roller 22. The rotating roller 22 is connected by a connecting belt 19. The belt 19 and the rotating motor 20 are connected for transmission. One end of the slide rail 14 is provided with a positioning plate 24. The rotating roller 22 passes through the positioning plate 24 and is rotatably connected to the positioning plate 24. A fixing clamp 10 is fixedly provided on the side of the guide rail 9. A photoelectric sensor 11 is provided at one end of the fixing clamp 10. A rotatable handle 7 is provided on the surface of the machine body 1. One end of the handle 7 passes through the machine body 1 and extends into the interior of the machine body 1. One end of the handle 7 is connected to the lead screw 15.

[0024] The cabinet 34 allows for temporary storage of test samples. The double doors 3 and handles 4 allow for easy opening of the cabinet 34, facilitating the placement of test samples inside. The flip-up cover 5 and handle 6 allow for easy inspection of the internal testing conditions of the machine body 1. The cover 5 can be flipped to a 90° position, providing unobstructed access for maintenance and reducing equipment downtime. Several rotating rollers 22 are distributed and supported to disperse the stress on the conveyor belt 26, preventing wear caused by stress concentration at a single point. The fixing clamp 10 uses conventional fixing clamps from existing technology. The fixed clamp 10 can clamp and fix the test sample. The photoelectric sensor 11 can sense the position of the test sample. The photoelectric sensor 11 detects the position of the sample in real time and triggers the pneumatic clamping action of the fixed clamp 10 to achieve precise positioning. By rotating the handle 7, the lead screw 15 can be rotated, so that the slide rail 14 slides along the base plate 17. This can move the slide rail 14 closer to or away from the positioning plate 24, and can convert the rotational motion into linear motion, so that the guide rail 9 moves closer to or away from the positioning plate 24, thereby adjusting the distance between the guide rails 9. This allows for quick adjustment of the test distance and adaptability to samples of different sizes.

[0025] The main control circuit board is also located inside the main unit 1. The control panel 8 is electrically connected to the main control circuit board via wires. The control panel 8 is equipped with several control buttons, a display screen, and switches. The main unit 1 also houses an environmental control module and an electrical testing module. The environmental control module includes a temperature and humidity sensor, a heater, a refrigeration unit, a humidity generator, and a circulating fan. The temperature and humidity sensor monitors the temperature (-40℃~150℃) and humidity (10%~95%RH) inside the main unit 1 in real time, using a PT100 high-precision probe. The heater and refrigeration unit use a PTC ceramic heating element combined with a semiconductor cooling chip (TEC) to achieve rapid temperature changes (±10℃ / min). The humidity generator combines an ultrasonic atomizer and a drying fan to precisely control humidity fluctuations (±3%RH). The circulating fan is a multi-axis centrifugal fan that ensures uniform temperature and humidity distribution in the main unit 1 (uniformity ≤±1℃ / ±5%RH). The electrical testing module includes: a programmable power supply, a matrix switch, and a data acquisition card. The programmable power supply is a programmable DC power supply (0-60V / 0-20A) that simulates power supply fluctuations on the circuit board. The matrix switch is a high-voltage relay matrix (256 channels) that switches test points and supports four-wire resistance measurement. The data acquisition card is a 16-bit ADC that simultaneously acquires voltage, current, and temperature signals (sampling rate 1MHz). The main control circuit board and core electronic components inside the main unit 1 all use conventional existing electronic components. The electric cylinder 28, rotating motor 20, and fixing fixture 10 of the aging test cabinet also use conventional existing technologies, which will not be described in detail here.

[0026] The pressure testing assembly 2 includes a fastening plate 27 fixedly installed inside the body 1 and an electric cylinder 28 installed at the bottom of the fastening plate 27. The output end of the electric cylinder 28 is provided with a retractable push rod 33. One end of the push rod 33 is provided with a pressing plate 32. One end of the electric cylinder 28 is provided with a mounting plate. The surface of the mounting plate is provided with a plurality of connecting rods 29, which are symmetrically arranged between adjacent connecting rods 29. One end of the connecting rod 29 is fixedly connected to the fastening plate 27. The surface of the mounting plate is fixedly provided with a plurality of bushings 30, which are symmetrically arranged between adjacent bushings 30. The surface of the mounting plate is provided with a plurality of fixed shafts 31, which are symmetrically arranged between adjacent fixed shafts 31. One end of the fixed shaft 31 extends to the outside of the mounting plate and is connected to the pressing plate 32. The fixed shaft 31 is movably connected to the bushings 30. The fixed shaft 31 does not contact or connect with the fastening plate 27.

[0027] The electric cylinder 28 drives the pressing plate 32 via the push rod 33, supporting dynamic loading of pressure from 0-10MPa. It can simulate combined vibration, impact, and static pressure conditions in real environments, achieving multi-dimensional pressure simulation. In practical use, the test sample to be tested is placed at one end of the guide rail 9. The throttle 7 on the outside of the machine body 1 is manually adjusted to rotate the lead screw 15, causing the slide rail 14 to slide along the base plate 17. This allows the slide rail 14 to move closer to or away from the positioning plate 24, converting rotational motion into linear motion. This allows the guide rail 9 to move closer to or away from the positioning plate 24, adjusting the distance between the guide rails 9. This enables quick adjustment of the test distance to suit the test sample. Once the appropriate distance is reached... The control panel 8 controls the rotating motor 20, which drives the connecting belt 19 and rotating roller 22 to rotate, causing the conveyor belt 26 and fixed roller 25 to rotate. The conveyor belt 26 transports the test sample to be tested into the machine body 1. When it is in the appropriate position, the photoelectric sensor 11 senses the position of the test sample and clamps it with the fixed clamp 10. After clamping, the electric cylinder 28 drives the push rod 33 and the pressing plate 32 to approach the test sample and simulate the vibration, impact, static pressure and other working conditions in the real environment to achieve multi-dimensional pressure simulation. After the pressure test, the aging test is carried out inside the machine body 1. The principle and working process of the aging test will not be described in detail here.

[0028] This embodiment of a pressure aging test cabinet includes a conveying assembly comprising a guide rail 9, a conveyor belt 26, a rotating roller 22, a lead screw 15, a chain 13, and a limiting part 23. The structure of the lead screw 15 and the chain 13 being linked together with the slide rail 14 for positioning supports rapid adjustment of the test distance, adapts to samples of different sizes, and enables continuous transport of test samples without deviation, thus enhancing the flexibility of the equipment.
