Description

Technical Field

[0001] This utility model relates to the field of component testing technology, specifically to a component aging test fixture. Background Technology

[0002] In the production process of electronic components, aging testing is a crucial step. Its purpose is to accelerate the aging process of components by simulating stress under actual working conditions, thereby discovering potential defects and early failures in advance, and improving the reliability and stability of the products.

[0003] A search revealed a utility model with Chinese patent publication number CN217385567U, which discloses a fixture for testing the aging performance of electronic components. The fixture includes a base, with support strips on the front and back sides of the top two sides of the base. Coarse adjustment guide rods are movably connected to the top and middle of each support strip. A movable clamping plate is fixedly connected to one side of each of the two coarse adjustment guide rods. A coarse adjustment screw is positioned between the two guide rods, with its middle section threaded to the top of the support strips. One end of the screw is movably connected to one side of the movable clamping plate. An X-shaped fork is provided on one side of the top of the movable clamping plate. The X-shaped fork includes a fixed clamping plate and a movable clamping plate. Multiple anti-slip strips are fixedly connected to the top of one side of the fixed clamping plate and the bottom of one side of the movable clamping plate. This utility model uses the two movable clamping plates to bring the X-shaped fork close together, clamping the electronic components on both sides. The multiple anti-slip strips prevent the electronic components from loosening during the aging performance testing process.

[0004] While this device securely clamps electronic components to prevent them from loosening, it has poor versatility for components of different specifications and types. Often, special tooling needs to be designed for specific components, which not only increases production costs but also reduces testing efficiency. In addition, the tooling has poor heat dissipation performance. During long-term aging tests, the heat generated by the components cannot be dissipated in time, which may lead to overheating and damage to the components, further affecting the reliability of the test. Utility Model Content

[0005] The purpose of this utility model is to provide a component aging test fixture in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model employs the following technical solution: a component aging test fixture, comprising: a test chamber; a lifting plate, the lifting plate being slidably installed between the two sides of the inner wall of the test chamber, and a lifting assembly for raising and lowering the height of the lifting plate being installed inside the test chamber; a mounting ring, the mounting ring being fixedly installed on the top of the lifting plate, and multiple movable plates being slidably installed in an array on the top of the mounting ring, and a movable assembly for moving one end of the multiple movable plates closer to or further away from each other being installed on the mounting ring; multiple clamping plates, each of which is detachably installed on one end of the multiple movable plates; and a heat dissipation assembly, the heat dissipation assembly being installed on the mounting ring for dissipating heat from the tested component.

[0007] Furthermore, the lifting assembly includes a drive motor fixedly installed at the bottom of the inner wall of the test chamber. A bidirectional threaded rod is fixedly installed at the output end of the drive motor, one end of which is rotatably connected to one side of the inner wall of the test chamber. Two sliding plates are symmetrically distributed and slidably installed at the bottom of the inner wall of the test chamber. A rotating plate is rotatably installed between the top of each of the two sliding plates and the bottom of the lifting plate.

[0008] Furthermore, the movable component includes an internal gear ring rotatably mounted on the top of the mounting ring, and multiple gears are rotatably mounted in an array on the top of the mounting ring. All of the multiple gears mesh with the internal gear ring. Multiple teeth are fixedly mounted in an array on one side of each of the multiple movable plates. The multiple gears mesh with the multiple teeth on the multiple movable plates respectively. A rotary motor for driving one of the gears to rotate is fixedly inserted on the mounting ring.

[0009] Furthermore, a positioning frame is installed on the top of each of the multiple movable plates, and a clamping plate is fixedly installed on one side of the clamping plate, the clamping plate being inserted into the positioning frame.

[0010] Furthermore, the heat dissipation assembly includes a fixing ring that is detachably mounted on the mounting ring, a filter plate is fixedly mounted on the top of the fixing ring, and a cooling fan is fixedly mounted on the inner wall of the fixing ring.

[0011] Furthermore, a threaded ring is fixedly installed at the bottom of the mounting ring, and the bottom end of the fixing ring is threadedly connected to the threaded ring.

[0012] Furthermore, a placement frame is fixedly installed on the top of the lifting plate.

[0013] Furthermore, two slidable closed plates are symmetrically distributed on the top of the test box, and a magnet is fixedly installed on one side of one of the closed plates, the magnet being magnetically connected to one side of the other closed plate.

[0014] The beneficial effects of this utility model are as follows: This invention uses a moving component to move multiple moving plates closer to or further away from the center of the mounting ring, allowing one end of each plate to move radially synchronously. This enables the clamping plates, which are detachably mounted on the ends of the multiple moving plates, to adaptively clamp components of different sizes and shapes, greatly improving the versatility of clamping different components. Furthermore, the heat dissipation component forces the heat accumulated on the surface of the components to be expelled, preventing excessive temperature rise that could lead to component parameter drift or permanent thermal damage. This significantly improves the compatibility and testing efficiency of the tooling for multiple specifications and types of components, avoiding the problems of high cost, poor heat dissipation, and low reliability associated with dedicated tooling.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figure 1-4 As shown, an embodiment of this utility model provides a component aging test fixture, comprising: a test chamber 1; The lifting plate 2 is slidably installed between the two sides of the inner wall of the test chamber 1. The interior of the test chamber 1 is equipped with a lifting assembly 3 for raising and lowering the height of the lifting plate 2. The top of the lifting plate 2 is provided with testing instruments.

[0019] Mounting ring 4 is fixedly mounted on the top of the lifting plate 2. Multiple movable plates 5 are slidably mounted on the top of the mounting ring 4 in an array. Movable components 6 are mounted on the mounting ring 4 to drive one end of the multiple movable plates 5 to move closer or further away from each other. Clamping plates 7, in multiple quantities, are detachably mounted on one end of multiple movable plates 5; Heat dissipation component 8 is mounted on the mounting ring 4 and is used to dissipate heat from the tested components.

[0020] The working principle of this component aging test fixture is as follows: The test chamber 1 serves as the overall load-bearing and protective structure. The lifting plate 2, which is slidably installed between the two sides of its inner wall, can move precisely in the vertical direction under the drive of the lifting assembly 3. This allows the mounting ring 4, its moving plates 5, the moving assembly 6, and the clamping plate 7 to be removed from the test chamber 1, facilitating the clamping and fixing of the components for aging testing. The multiple moving plates 5, which are arranged in an array on the top of the mounting ring 4, can move synchronously radially at their ends, either near or away from the center of the mounting ring 4, driven by the moving assembly 6. This allows the clamping plates, which are detachably installed at the ends of the multiple moving plates 5, to be detachably mounted. 7 can adaptively clamp components of different sizes, shapes, and pin arrangements. The clamping plate 7 can be made of high-temperature resistant silicone, polyimide, or metal spring material, and its versatility can be further improved by replacing the modular chuck with different curvatures or toothed contact surfaces. During the test, the heat dissipation component 8 set on the mounting ring 4 continuously forces the heat accumulated on the surface of the component to be discharged, avoiding excessive temperature rise that could cause component parameter drift or permanent thermal damage. This significantly improves the compatibility and testing efficiency of the fixture for multiple specifications and types of components, and avoids the problems of high cost, poor heat dissipation, and low reliability caused by dedicated fixtures.

[0021] like Figure 2 As shown, in some embodiments, the lifting assembly 3 includes a drive motor 31 fixedly installed at the bottom of the inner wall of the test chamber 1. A bidirectional threaded rod 32 is fixedly installed at the output end of the drive motor 31, one end of which is rotatably connected to one side of the inner wall of the test chamber 1. Two sliding plates 33 are symmetrically distributed and slidably installed at the bottom of the inner wall of the test chamber 1. A rotating plate 34 is rotatably installed between the top of each of the two sliding plates 33 and the bottom of the lifting plate 2.

[0022] When the drive motor 31, which is fixedly installed at the bottom of the inner wall of the test chamber 1, is powered on, it outputs rotational power, which drives the bidirectional threaded rod 32 fixed at its output end to rotate synchronously. The other end of the bidirectional threaded rod 32 is rotatably connected to one side of the inner wall of the test chamber 1 through a bearing to maintain coaxiality and stability. The surface of the bidirectional threaded rod 32 has two external threads with opposite directions of rotation, which form a helical transmission pair with two sliding plates 33 that are symmetrically slidably installed at the bottom of the inner wall of the test chamber 1. When the drive motor 31 rotates forward, the two sliding plates 33 are restricted by the guide rail or slide groove and can only move away from each other in the horizontal direction, so that the rotating plate 34 gradually changes from inclined to vertical, and its vertical force increases, lifting the lifting plate 2 and the mounting ring 4 above it and the component under test to the required test height. Conversely, when the drive motor 31 rotates in reverse, the two sliding plates 33 move closer to each other, and the lifting plate 2 descends smoothly, which facilitates the use and storage of the clamping structure.

[0023] like Figure 3 As shown, in some embodiments, the moving component 6 includes an internal gear ring 61 rotatably mounted on the top of the mounting ring 4. A plurality of gears 62 are rotatably mounted in an array on the top of the mounting ring 4, and all of the gears 62 mesh with the internal gear ring 61. A plurality of teeth 63 are fixedly mounted in an array on one side of each of the plurality of moving plates 5. The plurality of gears 62 mesh with the plurality of teeth 63 on the plurality of moving plates 5 respectively. A rotary motor 64 for driving one of the gears 62 to rotate is fixedly inserted into the mounting ring 4.

[0024] When the rotating motor 64, which is fixedly inserted on the mounting ring 4, is powered on, it drives one of the gears 62, which is fixedly connected to its output shaft, to rotate. This gear 62 acts as the driving wheel, driving the internal gear ring 61, which meshes with it, to rotate coaxially at the top of the mounting ring 4. The rotation of the internal gear ring 61 simultaneously meshes with all the other gears 62 distributed in a ring array along the top of the mounting ring 4, so that all gears 62 rotate synchronously and in the same direction. Each gear 62 meshes with the teeth 63 distributed in an array on the side edge of the corresponding moving plate 5, converting the circular motion into linear motion, thereby pushing all moving plates 5 to slide synchronously in the radial direction. When the rotating motor 64 rotates clockwise, each moving plate 5 synchronously converges towards the center of the mounting ring 4, and the clamping plate 7 installed at its end tightens accordingly to adapt to and securely clamp small-sized components. Conversely, when the rotating motor 64 rotates counterclockwise, the moving plates 5 synchronously move outward, and the clamping plate 7 opens to release or adapt to large-sized components.

[0025] like Figure 2 As shown, in some embodiments, a positioning frame 9 is installed on the top of each of the multiple movable plates 5, and a clamping plate 10 is fixedly installed on one side of the clamping plate 7, with the clamping plate 10 inserted into the positioning frame 9.

[0026] The clamping plate 10 on one side of the clamping plate 7 is inserted vertically into the positioning frame 9 at the top of the corresponding moving plate 5 to form a gapless lock. This ensures zero movement of the clamping plate 7 under radial clamping force and allows it to be quickly pulled out by hand when different specifications of clamping surfaces need to be replaced, thus enabling the quick replacement of the clamping plate 7.

[0027] like Figure 4 As shown, in some embodiments, the heat dissipation assembly 8 includes a fixing ring 81 detachably mounted on the mounting ring 4, a filter plate 82 fixedly mounted on the top of the fixing ring 81, and a cooling fan 83 fixedly mounted on the inner wall of the fixing ring 81.

[0028] The fixing ring 81, which can be detachably installed on the mounting ring 4, provides rigid support for the cooling fan 83. The filter plate 82 fixed on its top forms a three-dimensional filter barrier at the front end of the airflow channel to prevent solder debris and other debris from falling off during the aging test from entering the cooling fan 83. The cooling fan 83 embedded in the inner wall of the fixing ring 81 rotates at high speed after being powered on, forcibly dissipating the heat accumulated on the surface of the components and inside the test chamber 1 along the axial direction.

[0029] like Figure 4 As shown, in some embodiments, a threaded ring 11 is fixedly installed at the bottom of the mounting ring 4, and the bottom end of the fixing ring 81 is threadedly connected to the threaded ring 11.

[0030] The threaded ring 11, which extends coaxially from the bottom of the mounting ring 4, provides precise thread guidance. The bottom of the retaining ring 81 is correspondingly provided with an internal thread. The two can be rigidly connected by a single turn of screwing.

[0031] like Figure 2 As shown, in some embodiments, a placement frame 12 is fixedly installed on the top of the lifting plate 2.

[0032] The placement frame 12 is used to place clamping plates 7 of different sizes and types.

[0033] like Figure 1 As shown, in some embodiments, two slidable closed plates 13 are symmetrically distributed on the top of the test box 1, and a magnet 14 is fixedly installed on one side of one of the closed plates 13, and the magnet 14 is magnetically connected to one side of the other closed plate 13.

[0034] When not performing aging tests, the two sealing plates 13 can be combined to seal the test chamber 1 and prevent dust from entering. The sealing plates 13 are made of iron and are magnetically connected to the magnet 14.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
