Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing technology, specifically to POM positioning screen. Background Technology
[0002] As electronic devices become increasingly integrated and miniaturized, heat sinks are being used more and more widely in electronic components. To improve the heat dissipation performance of electronic devices, thermal adhesive is typically printed onto the surface of the heat sink. The process of printing thermal adhesive is crucial to ensuring the performance and reliability of electronic devices.
[0003] The conventional solution is to use a stainless steel stencil for printing thermal adhesive, but this traditional method requires manual alignment for each job. Frequent manual alignment not only increases preparation time but also reduces overall production efficiency. Manual alignment requires operators to repeatedly adjust the stencil, increasing labor intensity, potentially causing operator fatigue, and also increasing the risk of operational errors. Positional deviations during manual alignment can lead to low printing accuracy, affecting the uniform distribution of the thermal adhesive and its heat dissipation effect, ultimately impacting the heat dissipation performance and lifespan of electronic devices.
[0004] Therefore, a POM positioning mesh plate is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a POM positioning mesh plate to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] The POM positioning mesh includes a base plate, a fixing frame is fixedly connected to the rear side of the top surface of the base plate, a mounting shell is fixedly connected to the top of the fixing frame, a centering placement component for lateral positioning of the heat sink is provided on the surface of the mounting shell, a longitudinal placement component for longitudinal positioning of the heat sink is installed on the surface of the base plate, and a mesh assembly is provided on the front side of the mounting shell.
[0008] Furthermore, the mesh assembly includes an aluminum alloy frame, in which a POM block is embedded in the middle, and the bottom shape and specifications of the POM block are adapted to the heat sink, and a steel mesh is embedded on the surface of the POM block.
[0009] Furthermore, the centering and placement assembly includes a first motor, which is fixedly installed on the inner wall of the mounting housing. A double-ended screw is fixedly connected to the output end of the first motor. A connecting rod is threadedly connected to the surface of the double-ended screw. A first sliding groove is formed through the bottom surface of the mounting housing, and the inner wall of the first sliding groove is slidably connected to the surface of the connecting rod. A push plate is fixedly connected to the end of the connecting rod.
[0010] Furthermore, the longitudinal placement assembly includes a second motor, which is fixedly mounted on the back of the substrate. The output end of the second motor is fixedly connected to a threaded post, and a U-shaped bracket is threadedly connected to the surface of the threaded post. A second sliding groove is formed through the top surface of the substrate, and the inner wall of the second sliding groove is slidably connected to the surface of the U-shaped bracket. Mounting plates are fixedly connected to the front of the fixing frame and the end of the U-shaped bracket, and rollers are rotatably connected to the surface of the mounting plates.
[0011] Furthermore, electric push rods are fixedly connected to both the left and right ends of the mounting shell, and connecting columns are fixedly connected to the telescopic ends of the electric push rods, with the ends of the connecting columns fixedly connected to the aluminum alloy frame.
[0012] Furthermore, the lateral length of the U-shaped bracket is less than the length of the heat sink.
[0013] The beneficial effects of this utility model are as follows:
[0014] The heat sink is placed on the top surface of the substrate. The vertical position of the heat sink is adjusted by the vertical placement component, and then the heat sink is centered and aligned by the centering placement component.

[0025] like Figures 1 to 4 As shown, the POM positioning mesh includes a base plate 1. A fixing frame 2 is fixedly connected to the rear side of the top surface of the base plate 1. A mounting shell 3 is fixedly connected to the top of the fixing frame 2. A centering and placement component 5 for lateral positioning of the heat sink is provided on the surface of the mounting shell 3. A longitudinal placement component 6 for longitudinal positioning of the heat sink is installed on the surface of the base plate 1. A mesh assembly 4 is provided on the front side of the mounting shell 3. More specifically, the heat sink is placed on the top surface of the base plate 1, and the longitudinal position of the heat sink is adjusted by the longitudinal placement component 6. Then, the heat sink is centered and aligned by the centering and placement component 5. After adjustment, the mesh assembly 4 is pressed onto the top of the heat sink to position it, and then thermal adhesive can be applied to the surface of the heat sink.
[0026] The stencil assembly 4 includes an aluminum alloy frame 401, with a POM block 402 embedded in the center of the frame. The bottom shape and specifications of the POM block 402 are adapted to the heat sink, and a steel mesh 403 is embedded on the surface of the POM block 402. It should be noted that when the heat sink is aligned, the POM block 402 is pressed onto the top of the heat sink. The bottom of the POM block 402 is cut out according to the shape of the heat sink to hold it in place, achieving positioning. The position of the steel mesh 403 can then be used to print thermal adhesive.
[0027] The centering assembly 5 includes a first motor 501, which is fixedly mounted on the inner wall of the mounting housing 3. A double-ended screw 502 is fixedly connected to the output end of the first motor 501. A connecting rod 503 is threaded onto the surface of the double-ended screw 502. A first sliding groove 504 is formed through the bottom surface of the mounting housing 3, and the inner wall of the first sliding groove 504 is slidably connected to the surface of the connecting rod 503. A push plate 505 is fixedly connected to the end of the connecting rod 503. More specifically, the operation of the first motor 501 drives the double-ended screw 502 to rotate, thereby causing the connecting rod 503 to move along the inner wall of the first sliding groove 504, which in turn moves the push plate 505. The two push plates 505 then center and align the radiator.
[0028] The vertically placed component 6 includes a second motor 601, which is fixedly mounted on the back of the substrate 1. The output end of the second motor 601 is fixedly connected to a threaded post 602. A U-shaped bracket 603 is threadedly connected to the surface of the threaded post 602. A second sliding groove 606 is opened through the top surface of the substrate 1, and the inner wall of the second sliding groove 606 is slidably connected to the surface of the U-shaped bracket 603. Mounting plates 604 are fixedly connected to the front of the fixing frame 2 and the end of the U-shaped bracket 603. A roller 605 is rotatably connected to the surface of the mounting plate 604. It should be noted that the heat sink is placed on top of the base plate 1 and between the front and rear mounting plates 604. The second motor 601 drives the threaded column 602 to rotate. Under the action of the thread, the U-shaped bracket 603 slides along the inner wall of the second slide groove 606, thereby moving the mounting plate 604. This allows the front and rear sides of the heat sink to finally fit against the surfaces of the front and rear rollers 605, thus initially limiting the longitudinal position of the rollers 605. By setting the rollers 605, it is easier for the push plate 505 to push the heat sink to move.
[0029] Electric push rods 7 are fixedly connected to both ends of the mounting shell 3. The telescopic ends of the electric push rods 7 are fixedly connected to connecting posts 8, and the ends of the connecting posts 8 are fixedly connected to the aluminum alloy frame 401. More specifically, by operating the electric push rods 7, their telescopic ends are extended, which can drive the connecting posts 8 and the mesh plate assembly 4 to move, so that the mesh plate assembly 4 can fit against the top of the radiator, thereby facilitating the application of adhesive to the radiator.
[0030] The lateral length of the U-shaped bracket 603 is less than the length of the heatsink. It should be noted that because the U-shaped bracket 603 is relatively short, it will not obstruct the heatsink when the push plate 505 is used to clamp the two sides of the heatsink.
[0031] In summary: The heat sink is placed on the top surface of the substrate 1, and its vertical position is adjusted by the vertical placement component 6. Then, the heat sink is centered and aligned by the centering placement component 5. After adjustment, the stencil component 4 is pressed onto the top of the heat sink to position it. Then, thermal adhesive can be applied to the surface of the heat sink. In use, the heat sink is automatically aligned and positioned without the need for manual adjustment. This makes the operation more convenient and ensures the accuracy of subsequent thermal adhesive printing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
