Description

Technical Field

[0001] This utility model relates to the field of electronic product testing equipment technology, specifically a suspension fixture for aging tests of electronic products. Background Technology

[0002] Aging tests for electronic products expose the products to simulated extreme environments such as high temperature and humidity, accelerating the exposure of potential defects such as soldering and material defects, thereby predicting service life, reducing market failure rate, screening for early failure components, reducing after-sales maintenance costs, and verifying the rationality of the design, such as the stability of circuits at high temperatures or the weather resistance of materials.

[0003] Aging chambers are commonly used equipment for testing the aging of electronic products. They use clamping or hanging fixtures to secure the products. However, during use, the weight of the products themselves, combined with the aging process caused by the test, can easily lead to products falling and being damaged. Aging chambers themselves lack protective functions for the tested products. Application number CN202322768544.X discloses an electronic product aging test device to prevent damage from falling objects. This device uses a fixing frame installed in the middle section of the inner wall of the chamber to support the electronic equipment or structural components being clamped and tested. This structure aims to protect the tested material from structural damage if it falls. However, this fixed shelf structure is not flexible enough for testing products of different sizes, requiring the fixing frame to be disassembled to adjust the internal space. Furthermore, the clamping operation inside the aging chamber is cramped and inconvenient. Utility Model Content

[0004] The technical problem this invention aims to solve is that when testing electronic products, the mounting bracket has limitations on the size of the product, making it impossible to make reasonable use of the internal testing space, adjust the protective position according to the product's hanging size, and the internal operating space is cramped and inconvenient.

[0005] To solve the above technical problems, the present invention provides the following technical solution: The present invention proposes a suspension fixture for aging tests of electronic products, including a base, the base having multiple sets of slots for air circulation at equal intervals along the width direction, a recessed platform on the base, a slide seat slidably disposed in the recessed platform, and two sets of suspension structures symmetrically disposed on the slide seat.

[0006] The suspension structure includes a turntable rotatably mounted on a slide block and a support column vertically mounted on the turntable. The support column has a sliding cavity inside and also includes an adjusting column with its lower end slidably mounted in the sliding cavity. The top of the adjusting column has a top plate and a suspension hook on the side wall of the top plate. A protective net plate for receiving and protecting products from falling is slidably mounted on the support column.

[0007] Preferred technical solution 1: The suspension hook is Z-shaped, and one end is magnetically inserted into the side wall of the top plate. The suspension end of the suspension hook is wavy.

[0008] Preferred technical solution 2: The supporting upright is provided with multiple sets of positioning holes at equal intervals along the height direction, the bottom side wall of the adjusting column is provided with a spring pin corresponding to the positioning hole, and the protective mesh plate is also provided with a process port.

[0009] Preferred technical solution 3: The support pole is provided with guide grooves on both sides, and the bottom of the protective mesh plate is provided with a slider. The slider is slidably disposed in the guide groove for guiding the lifting and lowering of the protective mesh plate. Multiple sets of positioning holes are provided at equal intervals along the height direction on the support pole. Positioning holes one and positioning holes two are located on both sides of the support pole. The slider is also provided with spring pin two corresponding to the positioning holes two.

[0010] Preferred technical solution four: A sign corresponding to the suspension hook is provided on one side of the top plate.

[0011] Preferred technical solution five: The slide is provided in multiple sets, and the multiple sets of slides make the maximum use of the internal space of the aging chamber according to the product hanging size.

[0012] Preferred technical solution six: Four sets of support legs are evenly distributed at the four corners of the bottom of the base, and handles are provided on both sides of the base.

[0013] The present invention proposes a suspension fixture for aging tests of electronic products. The beneficial effects achieved by adopting the above structure are as follows:

[0014] (1) Multi-dimensional adjustment improves space utilization: Through the three-dimensional space adjustment capability of horizontal sliding of the slide block, vertical lifting of the adjustment column and linkage adjustment of the protective mesh plate, it can be used to suspend electronic products of different sizes, effectively prevent the products from falling, and improve the internal space utilization of the aging chamber.

[0015] (2) Magnetic quick-release optimizes operation efficiency: The Z-type wave suspension hook adopts a magnetic plug-in structure, which allows the product hanging operation to be completed outside the equipment and then pushed into the aging box as a whole. The time for a single product change is shortened, and the efficiency is improved compared with the traditional method. In addition, the wave-shaped hook body realizes the natural separation of cables and avoids tangling.

[0016] (3) Modular expansion enhances practicality: The multi-slide layout forms a matrix-style suspension station, supporting simultaneous testing of multiple product groups; the ergonomic design of the bottom support legs and handles reduces the weight of a single person handling the equipment to a minimum, and the label ensures that batch test data is traceable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0025] Example 1

[0026] like Figures 1-4As shown, the technical solution adopted by this utility model is as follows: a suspension fixture for aging test of electronic products, including a base 1, the base 1 is provided with multiple sets of slots 2 for air circulation at equal intervals along the width direction, the base 1 is provided with a recess, a slide seat 3 is slidably provided in the recess, and two sets of suspension structures 4 are symmetrically provided on the slide seat 3.

[0027] like Figures 1-2 As shown, the suspension structure 4 includes a turntable 5 rotatably mounted on the slide block 3, and a support rod 6 vertically mounted on the turntable 5. The support rod 6 has a sliding cavity inside, and also includes an adjusting column 7 with its lower end slidably mounted in the sliding cavity. The top of the adjusting column 7 is provided with a top plate 8, and a suspension hook 9 is provided on the side wall of the top plate 8. A protective net plate 10 for receiving and protecting the product from falling is slidably mounted on the support rod 6. The protective net plate 10 and the adjusting column 7 both slide up and down, matching each other, and are suitable for suspending and fixing products of different sizes. The slide block 3 is provided with multiple sets, and the multiple sets of slide blocks 3 make the maximum use of the internal space of the aging chamber according to the product suspension size.

[0028] like Figure 3 As shown, the support pole 6 is provided with multiple sets of positioning holes 11 at equal intervals along the height direction, the bottom side wall of the adjusting column 7 is provided with spring pins 12 corresponding to the positioning holes 11, and the protective net plate 10 is also provided with a process port to avoid the spring pins 12 when lifting and lowering.

[0029] like Figure 4 As shown, the support pole 6 has guide grooves 13 on both sides, and the bottom of the protective mesh plate 10 has a slider 14. The slider 14 is slidably disposed in the guide groove 13 for guiding the lifting and lowering of the protective mesh plate 10. The support pole 6 has multiple sets of positioning holes 15 equidistantly arranged along the height direction. Positioning hole 11 and positioning hole 15 are located on both sides of the support pole 6. The slider 14 is also provided with spring pins 16 corresponding to the positioning holes 15. By moving the spring pins 16, the slider 14 can be flexibly raised and lowered, thereby adjusting the protective mesh plate 10 to adapt to the product size.

[0030] Example 2

[0031] Based on Example 1, such as Figure 1 and Figure 3 As shown, the suspension hook 9 is Z-shaped, with one end magnetically attached to the side wall of the top plate 8. The hanging end of the suspension hook 9 has a wavy design, facilitating the spacing of multiple products via cables. The magnetic attachment allows for easy disassembly and installation, enabling external hanging and providing greater operational space. A label 17 corresponding to the suspension hook 9 is located on one side of the top plate 8 for recording product information. Four sets of support legs 18 are evenly distributed at the four corners of the base 1, and handles 19 are located on both sides of the base 1 for overall handling.

[0032] The tooling is moved into the aging chamber using the handles 19 on both sides of the base 1, with the four sets of support legs 18 at the bottom ensuring stable placement. Observe the internal spatial layout of the aging chamber. According to the size requirements of the product to be tested, slide multiple sets of slide blocks 3 laterally along the recessed platform of the base 1 to make the spacing between adjacent slide blocks adapt to the product width. If it is necessary to expand the testing capacity, the number of slide blocks 3 can be increased in the recessed platform of the base 1 to form a matrix suspension array. Pull the adjusting column 7 upward to raise the top plate 8 and the suspension hook 9 to the target height. When the spring pin 12 at the bottom of the adjusting column 7 is aligned with the positioning hole 11 on the support column 6, the spring pin automatically pops out and locks. The protective mesh plate 10 is adjusted synchronously: manually pull the spring pin 16 on the slider 14 and slide the protective mesh plate 10 along the guide grooves 13 on both sides of the support column 6 to keep its height at a set distance from the adjusting column 7. The protective mesh plate is 20-50mm below the product. Release the spring pin 16 to embed it into the positioning hole 15 to complete the fixation. Observe the position of the spring pin 12 through the process port to ensure that there is no interference when the protective mesh plate 10 is raised or lowered.

[0033] The Z-shaped wave suspension hook 9 is magnetically attached to the side wall of the top plate 8, corresponding to technical solution one. If the hook type needs to be changed, the old suspension hook is pulled out and replaced with a new one. The electronic product cables are hung on the wave-shaped end of the suspension hook 9 outside the aging chamber, and the cables are separated by the wave intervals. The main body of the product is suspended directly above the protective mesh plate 10. The slide 3 is pushed into the recessed platform of the base 1 to make slight adjustments to ensure that the spacing between adjacent products is uniform and the base slot 2 forms an air circulation channel. The product number, test time and other information are recorded on the identification plate 17 on the side wall of the top plate 8, corresponding to technical solution four. The magnetic suspension hook 9 is disassembled for cleaning and maintenance. The tooling is removed by the handle 19, and the dust accumulated in the base slot 2 is cleaned to ensure smooth airflow for the next test.
