Description

Technical Field

[0001] This utility model relates to the field of electronic product testing equipment technology, specifically an adjustable temperature aging rack. Background Technology

[0002] In the product manufacturing industry, aging testing is a crucial step in ensuring product quality. As an important piece of equipment for aging testing, the aging rack has undergone several stages of development. Early aging racks had relatively simple structures and single functions. With the development of the manufacturing industry and the increasing demands for aging testing, aging racks have gradually diversified. Currently, there are various types of aging racks on the market, the simplest of which is the Simple Rack, which is generally constructed from aluminum profiles and partitions. During aging testing, staff install and secure the power cords and other necessary components on the rack, and after connecting the power, the Burnin burn-in test can begin.

[0003] However, existing aging racks still have many shortcomings in practical use: First, they lack a heat dissipation system. Products generate heat during aging tests, and without a heat dissipation system, the temperature can affect the product's performance, leading to defects. Second, they lack a temperature monitoring system. Temperature is crucial to testing, but existing aging racks cannot monitor product temperature in real time during testing. Third, they cannot accurately position and limit the product. Different products vary in size and appearance; if the product shakes during testing, it may cause defects. Existing aging racks cannot accurately fix, position, and limit the product according to its actual appearance and size. Fourth, the power supply system is unsafe. When multiple products are tested simultaneously, the power load increases, posing risks of overload and short circuits.

[0004] For example, Chinese patent application number CN201820880501.7 discloses an aging rack for PCBA board aging testing, relating to the field of aging racks, used for aging tests of PCBA boards. It includes a frame, a support plate, a power supply component, a clamping component, and a heat dissipation component. The frame is placed on the ground, the support plate is horizontally positioned to support the PCBA board, multiple support plates are spaced vertically and assembled with the frame, the power supply component is assembled on the support plate, the clamping component is assembled on the support plate to clamp the PCBA board so that the PCBA board is perpendicular to the support plate, and the heat dissipation component is assembled on the frame. Although this utility model includes a heat dissipation component and a power supply component, it lacks a temperature monitoring system, resulting in the cooling fan constantly running, which wastes energy and fails to ensure that the aging rack is at a suitable temperature for burn-in testing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable temperature aging rack that can monitor temperature changes in real time during burn-in testing, thereby ensuring that the burn-in test is conducted at a suitable temperature and improving the accuracy of test results. This solves the problem of not being able to monitor temperature changes in real time during burn-in testing.

[0006] To achieve the above-mentioned goal of real-time monitoring of temperature changes during burn-in testing, thereby ensuring that the burn-in test is conducted at a suitable temperature and improving the accuracy of test results, this utility model provides the following technical solution: an adjustable temperature aging rack, including a rack body, wherein the interior of the rack body is divided into a first cavity and a second cavity by vertical partitions, and at the same time, horizontally distributed multi-layer planar plates spatially divide each cavity into layers, forming a three-dimensional storage architecture.

[0007] Multiple cooling fans are evenly distributed on both sides of the frame. Each cooling fan is connected to an independent controller, which can be used to adjust the fan speed.

[0008] Temperature monitors are fixedly installed on the partition above each floor plan.

[0009] A support member, which is equidistantly mounted above the flat plate;

[0010] The electrical control box is installed at the bottom of the frame. The electrical control box independently controls the power supply of each layer of the support frame and is equipped with a circuit breaker protection device.

[0011] Preferably, the first cavity and the second cavity are each provided with four horizontally distributed planar plates. The planar plates are evenly spaced and separate the first cavity from the second cavity from top to bottom, forming a five-layer three-dimensional spatial structure.

[0012] Preferably, sixteen cooling fans are evenly distributed on both sides of the frame, and two fans are symmetrically arranged at each layer where a load-bearing component is installed.

[0013] Preferably, the bottom of the support member is fixedly mounted on the flat plate by two positioning pins.

[0014] Preferably, a baffle is provided on the outside of the electrical control box.

[0015] Preferably, casters are installed at all four corners of the bottom of the frame.

[0016] Preferably, each of the casters is equipped with a fixing plate on its side.

[0017] Compared with the prior art, this utility model provides an adjustable temperature aging rack, which has the following beneficial effects:

[0018] This temperature-adjustable aging rack features scientifically arranged cooling fans on its side walls, allowing for targeted heat dissipation and rapid temperature regulation. Temperature monitors are securely installed on the partitions above each layer of the rack, providing real-time and accurate temperature data for each layer. Evenly spaced support members on the flat panels provide stable support for the items being tested. The electrical control box at the bottom of the rack serves as the core control unit, capable of independently controlling the power supply to each layer. It not only flexibly adjusts the working status of each layer but also incorporates a built-in circuit breaker to effectively prevent overload, short circuits, and other abnormal conditions, ensuring comprehensive equipment safety.

[0025] 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.

[0026] like Figures 1-5As shown, an adjustable temperature aging rack includes a frame body 1. The frame body 1 adopts a frame structure, and its interior is precisely divided into independent first chambers 21 and second chambers 22 by vertical partitions 2. At the same time, horizontally distributed multi-layer planar plates 3 spatially layer each chamber, forming a regular three-dimensional storage architecture. Cooling fans 8 are scientifically arranged on the side walls of the frame body 1. Each cooling fan 8 is connected to an independent controller. The controller can adjust the wind speed of the cooling fan 8, and can directionally dissipate heat from the chamber as needed to achieve rapid temperature regulation. In this embodiment, the controller and sensors, etc., are all commercially available components.

[0027] Temperature monitors 4 are securely installed on the partitions 2 above each layer of the planar panel 3, enabling real-time and accurate monitoring of temperature data for each layer. Bearing members 5 are evenly spaced on the planar panel 3 to provide stable support for the items being tested. The electrical control box 6 at the bottom of the frame 1 serves as the core control unit, capable of independently controlling the power supply to each layer of the support frame. It not only flexibly adjusts the working status of each layer but also has a built-in circuit breaker protection device to effectively prevent circuit overload, short circuits, and other abnormal situations, ensuring comprehensive equipment operational safety.

[0028] like Figure 1 and Figure 2 As shown, in this embodiment, four horizontally distributed planar plates 3 are provided inside the first cavity 21 and the second cavity 22. The planar plates 3 are evenly spaced and separate the first cavity 21 and the second cavity 22 from top to bottom, forming a five-layer three-dimensional space structure. This can fully meet the diverse needs of layered use and provide independent and sufficient placement areas for aging tests of different items.

[0029] In this embodiment, sixteen cooling fans 8 are evenly distributed on both side walls of the frame 1, and two fans are symmetrically arranged at each position where the load-bearing component 5 is installed on each layer. This layout ensures that each layer where the test item is placed can obtain a balanced and efficient heat dissipation effect, which can quickly remove the heat generated during the aging process, maintain the temperature stability inside the frame 1, and effectively improve the efficiency and reliability of the aging test.

[0030] like Figure 5 As shown, in this embodiment, the bottom of the carrier 5 is fixedly installed on the flat plate 3 by two positioning pins 51; after the positioning pins 51 pass through the reserved holes of the carrier 5, they are tightly embedded in the corresponding positioning holes of the flat plate 3 to form a reliable mechanical connection structure, which can not only ensure the accuracy of the installation position of the carrier 5, but also provide stable support force, effectively preventing the carrier 5 from shifting or shaking during use, and ensuring the stability and safety of the aging test process.

[0031] like Figure 1As shown, in this embodiment, a baffle 61 is provided on the outside of the electrical control box 6. The baffle 61 is made of a sturdy and durable material and is installed in close contact with the outer contour of the electrical control box 6. It can not only effectively prevent external dust and debris from entering the electrical control box 6, reducing the risk of circuit failure caused by foreign objects, but also provide physical protection for the electrical control box 6, avoiding damage to internal precision components from external collisions. At the same time, the design of the baffle 61 can also play a certain role in electromagnetic shielding, ensuring the stable operation of the electrical control box 6 and extending its service life.

[0032] like Figure 1 Figure 2 and Figure 3 As shown, in this embodiment, casters 7 are installed at all four corners of the bottom of the frame 1. These casters 7 are equipped with a flexible steering mechanism and a locking device, allowing for 360-degree free rotation. This facilitates easy movement of the aging frame by operators to adjust its position and optimize its spatial layout. Once the aging frame is moved to the designated position, the locking device quickly secures the casters 7, ensuring the frame 1 remains stable and does not shift. This satisfies the need for flexible movement of the equipment while also ensuring its stability and safety during operation.

[0033] Furthermore, each of the casters 7 is equipped with a fixing plate 71 on its side. The fixing plate 71 is made of high-strength alloy material and is linked to the casters 7 through a precision mechanical structure. When it is necessary to fix the aging rack, simply step on or turn the control component, and the fixing plate 71 can quickly press down and fit tightly against the ground. With its strong friction and grip, it can firmly lock the casters 7, effectively preventing the frame 1 from shifting due to external force or load. When unlocking, the fixing plate 71 can quickly spring back to its original position, allowing the casters 7 to immediately regain their flexible rotation performance, achieving an efficient switch between the aging rack's ease of movement and its fixed stability.

[0034] Working Principle: Assembly of the Aging Rack: First, assemble the rack 1 according to the design requirements, ensuring a stable frame structure. Then, install flat panels 3 on each layer of rack 1, accurately installing positioning pins 51 in their respective positions according to the design of the flat panels 3. Next, install cooling fans 8 on both sides of rack 1 and connect the controller wiring. Install temperature monitors 4 on each layer partition 2 and connect them to the control system. Finally, install the electrical control box 6 at the bottom of rack 1, connecting the power supply lines to each layer flat panel 3, ensuring the circuit breaker protection device functions properly.

[0035] Product testing operation procedure: During product aging testing, the operator first places the product in the groove 52 of the support 5 and secures it using the support 5 and positioning pins 51. Then, the product is connected to the power supply via the electrical control box 6 for testing. During the test, the temperature monitor 4 monitors the temperature of each layer of the flat panel 3 in real time and feeds the temperature information back to the control system. If the temperature exceeds the set range (e.g., 19-21℃), the control system will automatically adjust the speed of the cooling fan 8 to enhance or reduce heat dissipation to maintain the temperature within a suitable range. Simultaneously, the operator can easily move the aging rack and adjust its position using the casters 7.

[0036] In summary, this temperature-adjustable aging rack, through the scientific arrangement of cooling fans 8 on the side wall of the rack body 1, can directionally expel heat from the cavity according to needs, achieving rapid temperature adjustment; temperature monitors 4 are firmly installed on the partitions 2 above each layer of flat plate 3, enabling real-time and accurate monitoring of temperature data for each layer; bearing members 5 are set on the flat plate 3 at equal intervals to provide stable support for the items to be tested; and the electrical control box 6 at the bottom of the rack body 1, as the core control unit, has the ability to independently control the power supply of each layer of the bearing rack, not only flexibly adjusting the working status of each layer, but also having a built-in circuit breaker protection device to effectively prevent abnormal situations such as circuit overload and short circuit, ensuring the safe operation of the equipment in all aspects.
