Description

Technical Field

[0001] This utility model relates to the field of silicone pad testing technology, specifically a testing device for the production of thermally conductive silicone pads. Background Technology

[0002] In the heat dissipation system of electronic devices, the performance parameters of thermal conductive silicone pads directly determine the heat dissipation efficiency. If the thermal conductivity is not up to standard, it will hinder the heat dissipation of the chip; if the thickness deviation is too large, it may result in an excessively large heat dissipation gap; if there are bubbles or impurities on the surface, it will disrupt the heat conduction path. The testing equipment consists of a multi-parameter testing unit, an automatic conveying system, a defect identification module, a data storage and analysis system, and a sorting mechanism. The silicone pad is conveyed to the testing area by the conveying system. The laser thickness gauge and thermal conductivity meter simultaneously collect the core parameters. The industrial camera captures the appearance image and the AI ​​algorithm identifies the defects. The system compares the results with preset standards to determine the level of defects. Finally, the sorting mechanism classifies and outputs the results.

[0003] However, the above-mentioned equipment has obvious shortcomings in use. Traditional testing equipment mostly uses single-point cylinder pressure, resulting in uneven pressure distribution and large deviations in silicone pad deformation data, which cannot truly reflect the product's pressure performance. Some equipment lacks pressure buffering, making the silicone pad easily damaged and rendering the test data invalid. In view of this, we propose a testing equipment for the production of thermal conductive silicone pads. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for the production of thermally conductive silicone pads, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A testing device for producing thermally conductive silicone pads includes a testing unit. A transparent outer shell is fixedly mounted on the testing unit. A cabinet door is hinged to the transparent outer shell. A handle is hinged to the testing unit. A testing assembly is provided on the testing unit, and the testing assembly includes: Mounting bracket, the detection device is fixedly mounted on the mounting bracket, the mounting bracket is fixedly mounted on the mounting bracket, the piston end of the hydraulic device is fixedly mounted on the pressing plate, and one end of the limit rod is fixedly mounted on the pressing plate; A limiting cylinder is fixedly installed on the mounting bracket, a limiting plate is fixedly installed on the other end of the limiting rod, a slide rail is fixedly installed on the detection device, and a slider is slidably installed on the slide rail; A movable plate is fixedly mounted on the slider. The movable plate has a placement groove, a detection sensor is fixedly mounted on the movable plate, and a support pad is fixedly mounted on the bottom of the movable plate.

[0006] In a further embodiment, multiple sets of the limiting rod, limiting cylinder, limiting plate, slide rail, and slider are provided.

[0007] In a further embodiment, a silicone pad body is placed in the placement slot on the movable plate, and the detection sensor is located below the silicone pad body.

[0008] In a further embodiment, the pressing plate is positioned above the movable plate, the placement groove, and the silicone pad body.

[0009] In a further embodiment, the limiting rod slides inside the limiting cylinder, and the limiting plate is positioned above the limiting cylinder.

[0010] In a further embodiment, the detection device is provided with an auxiliary component, which includes a baffle. The baffle is fixedly installed on the detection device, a sliding box is fixedly installed on the detection device, a straight rod is fixedly installed on the sliding box, and a block is fixedly installed at the bottom of the support pad, with a limit groove fixedly installed on the block.

[0011] In a further embodiment, the baffle is positioned in front of the movable plate, the block slides inside the sliding box, and the straight rod passes through the limiting groove on the block.

[0012] Compared with the prior art, this utility model provides a testing device for the production of thermally conductive silicone pads, which has the following beneficial effects: 1. This testing equipment for the production of thermally conductive silicone pads, in order to meet the requirements of efficient screening of product performance in mass production, is equipped with a testing component. This component, in conjunction with a hydraulic device, pushes the pressing plate to descend at a uniform speed, applying uniform pressure to the silicone pad body in the slot where the moving plate is placed. The limiting rod slides along the limiting cylinder, and the limiting plate prevents the pressing plate from descending excessively and damaging the silicone pad. The detection sensor under the moving plate collects the deformation data, thermal conductivity and other parameters of the silicone pad after being compressed in real time to determine whether the product meets the standard.

[0013] 2. The testing equipment for the production of thermal conductive silicone pads includes an auxiliary component to ensure the reliability and consistency of the test results. When the moving plate moves the silicone pad, the block at the bottom of the support pad slides along the slide box. The straight rod passes through the limiting groove of the block to form a guide, ensuring that the moving plate always moves in a straight line and avoiding uneven force on the pressing plate due to the silicone pad shifting. When the moving plate reaches the testing position, the baffle stops the moving plate from moving forward and controls the alignment of the silicone pad and the pressing plate.

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.

It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0018] Please see Figures 1-5 This utility model provides a technical solution: A testing device for producing thermally conductive silicone pads includes a testing device 1, a transparent outer shell 2 fixedly mounted on the testing device 1, a cabinet door 3 hinged to the transparent outer shell 2, and a handle 4 hinged to the testing device 1.

[0019] In one embodiment of this utility model, a detection component 5 is provided on the detection device 1. The detection component 5 includes a mounting frame 51. The mounting frame 51 is fixedly mounted on the detection device 1. A hydraulic device 52 is fixedly mounted on the mounting frame 51. A pressing plate 53 is fixedly mounted on the piston end of the hydraulic device 52. One end of a limit rod 54 is fixedly mounted on the pressing plate 53. A limit cylinder 55 is fixedly mounted on the mounting frame 51. A limit plate 56 is fixedly mounted on the other end of the limit rod 54. A slide rail 57 is fixedly mounted on the detection device 1. A slider 58 is slidably mounted on the slide rail 57. A movable plate is fixedly mounted on the slider 58. 59. A placement groove 510 is provided on the movable plate 59. A detection sensor 511 is fixedly installed on the movable plate 59. A support pad 512 is fixedly installed at the bottom of the movable plate 59. Multiple sets of limiting rods 54, limiting cylinders 55, limiting plates 56, slide rails 57 and sliders 58 are provided. A silicone pad body 6 is placed in the placement groove 510 on the movable plate 59. The detection sensor 511 is located below the silicone pad body 6. The pressing plate 53 is located above the movable plate 59, the placement groove 510 and the silicone pad body 6. The limiting rod 54 slides inside the limiting cylinder 55. The limiting plate 56 is located above the limiting cylinder 55.

[0020] In this embodiment, before testing, the cabinet door 3 of the transparent outer shell 2 is opened, and the silicone pad body 6 is placed into the placement slot 510 of the moving plate 59. The moving plate 59 is pushed, and the slider 58 at its bottom slides along the slide rail 57 of the testing device 1, conveying the silicone pad body 6 directly below the pressing plate 53. At the same time, the support pad 512 at the bottom of the moving plate 59 can buffer the contact pressure between the moving plate 59 and the testing device 1 to avoid wear on the parts. The hydraulic device 52 on the mounting bracket 51 is activated, and its piston end pushes the pressing plate. The pressing plate 53 descends at a constant speed, applying uniform pressure to the silicone pad body 6. During the descent of the pressing plate 53, the limiting rod 54 slides along the limiting cylinder 55 of the mounting frame 51 to ensure that the pressing plate 53 applies pressure vertically. When the limiting plate 56 touches the limiting cylinder 55, it restricts the pressing plate 53 from continuing to descend, avoiding excessive pressure that could damage the silicone pad body 6. At the same time, the detection sensor 511 on the moving plate 59 collects key parameters such as the deformation data and thermal conductivity of the silicone pad body 6 after being compressed in real time, and feeds the data back to the detection system.

[0021] In one embodiment of this utility model, the detection device 1 is provided with an auxiliary component 7, which includes a baffle 71. The baffle 71 is fixedly installed on the detection device 1, and a sliding box 72 is fixedly installed on the detection device 1. A straight rod 73 is fixedly installed on the sliding box 72. A block 74 is fixedly installed at the bottom of the support pad 512. A limiting groove 75 is fixedly installed on the block 74. The baffle 71 is located in front of the moving plate 59. The block 74 slides inside the sliding box 72, and the straight rod 73 passes through the limiting groove 75 on the block 74.

[0022] In this embodiment, during the movement of the moving plate 59 and the silicone pad body 6, the block 74 at the bottom of the support pad 512 slides along the slide box 72 of the detection device 1. At the same time, the straight rod 73 passes through the limiting groove 75 of the block 74, forming a double guide structure. This strictly limits the movement direction of the moving plate 59, preventing the silicone pad body 6 from shifting and causing uneven force on the pressing plate 53, which would affect the accuracy of the detection data. When the moving plate 59 moves to the detection position, its front end abuts against the baffle 71 of the detection device 1. The baffle 71 prevents the moving plate 59 from moving forward, controlling the alignment of the silicone pad body 6 and the pressing plate 53, and ensuring that the pressing position and pressing angle are consistent during each detection.

[0023] In this application, all electrical components are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the detection device 1, the hydraulic device 52, and the detection sensor 511. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. In addition, the standard parts are all conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art.

[0024] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that each electrical appliance can work normally. The components are all general standard parts or components known to those skilled in the art.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
