[0002] In many industrial fields such as electronics, medical, and automotive, silicone rubber is widely used in the manufacture of key components such as seals, shock absorbers, and insulation due to its excellent elasticity, aging resistance, insulation, and chemical stability. Especially in applications with extremely high precision requirements, such as the packaging of precision electronic components and the sealing connection of medical equipment, the coating and molding process of silicone rubber must achieve extremely high precision to ensure the performance and reliability of the product.

[0003] As an important auxiliary tool, bonding jigs have gradually received widespread attention and application. The main function of bonding jigs is to provide stable support and positioning during the silicone rubber coating process, ensuring that the material can be accurately molded according to the predetermined shape and size. However, existing bonding jigs for precise molding of silicone rubber coating suffer from problems such as deformation and displacement of the silicone rubber material during the coating process due to its inherent flexibility. This makes it difficult to guarantee the dimensional accuracy of the product, which in turn affects the precise fit with other components. At the same time, the device lacks effective positioning and fixing in the bonding stage, causing deviations in the bonding position of the silicone rubber material and resulting in unstable bonding strength. Consequently, quality problems such as delamination and cracking occur during product use, reducing the reliability and service life of the product. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-5 As shown, an adhesive jig for precise molding of silicone rubber coating includes a base 1 and two sets of limiting plates 2. The two sets of limiting plates 2 are respectively fixed on both sides of the base 1. Several sets of positioning blocks 3 are fixed on the top of the base 1. The base 1 serves as the basic support structure of the entire jig, providing installation positions for other components, ensuring the overall stability and reliability of the jig, and bearing various forces during the entire jig and silicone rubber coating molding process. The limiting plates 2 provide tracks for the installation and movement of the pressure plate 7, restricting the movement direction of the pressure plate 7 so that it can only move up and down along the inner wall of the limiting plates 2, thereby achieving effective pressing and positioning of the silicone rubber coated part on the base plate 4. The positioning blocks 3 are inserted into the inner wall of the base plate 4 for preliminary positioning of the base plate 4, ensuring the accurate position of the base plate 4 on the base 1, and providing a reference for subsequent snap-fit ​​fixing and silicone rubber coating molding.

[0024] The base plate 4 is positioned above the base 1, and its inner wall is inserted into the outer side of the positioning block 3. A first gasket 5 is provided on the top of the base plate 4. The base 1 has a locking mechanism 6 for fixing the base plate 4 inside. The base plate 4 serves as a support platform for silicone rubber coating, used to place the silicone rubber material to be coated. Its inner wall is inserted into the positioning block 3, and its bottom is fixed to the base 1 by the locking mechanism 6. The first gasket 5 is provided on the top to protect the silicone rubber material and ensure the flatness of the coating surface. The first gasket 5 is located on the top of the base plate 4 to buffer and protect the silicone rubber material, preventing direct contact between the silicone rubber material and the base plate 4 and causing damage. At the same time, it ensures the flatness of the silicone rubber coating surface and improves the coating quality. The locking mechanism 6 can lock the base plate 4 through its internal structure, thereby fixing the base plate 4.

[0025] The pressure plate 7 is located on the inner wall of the limiting plate 2, and the pressure plate 7 and the base plate 4 are designed symmetrically. A second gasket 8 is provided at the bottom of the pressure plate 7. A moving mechanism 9 is provided on the other side of the limiting plate 2 to move the pressure plate 7. The pressure plate 7 and the base plate 4 are designed symmetrically. Under the drive of the moving mechanism 9, the pressure plate 7 moves downward to press the silicone rubber material placed on the base plate 4, ensuring that the silicone rubber material remains stable during the coating process and preventing displacement or deformation, thus ensuring the accuracy and quality of the coating. The second gasket 8 is located at the bottom of the pressure plate 7, which serves to buffer and protect the silicone rubber material, preventing the pressure plate 7 from directly contacting the silicone rubber material and causing damage. At the same time, it ensures the flatness of the pressing surface and makes the silicone rubber material bear force evenly. The moving mechanism 9 can drive the pressure plate 7 to move downward through its internal structure, thereby pressing the silicone rubber material placed on the base plate 4.

[0026] The snap-fit ​​mechanism 6 includes four sets of springs 61 fixed to the inner wall of the base 1. The four sets of springs 61 are designed symmetrically from left to right. A movable plate 62 is fixed to one end of each spring 61. A hook 63 is fixed to the top of the movable plate 62. The outer side of the hook 63 snaps into the inner wall of the base plate 4. The springs 61 provide elastic force to the movable plate 62, enabling the movable plate 62 to automatically reset. When the pull rod 13 is pulled, the spring 61 is compressed. When the pull rod 13 is released, the spring 61 pushes the movable plate 62 to reset, causing the hook 63 to snap into the inner wall of the base plate 4. The movable plate 62 moves left and right under the action of the springs 61, driving the hook 63 to move, thereby achieving snap-fit ​​or separation from the base plate 4, thus completing the fixing or release of the base plate 4. The hook 63 snaps into the inner wall of the base plate 4, fixing the base plate 4 to the base 1, preventing the base plate 4 from moving during the silicone rubber coating process, and ensuring the accuracy and stability of the coating.

[0027] The moving mechanism 9 includes a threaded rod 91 vertically arranged on the outside of the limiting plate 2. A movable block 92 is slidably connected to the inner wall of the limiting plate 2, and the inner wall of the movable block 92 is threadedly connected to the outside of the threaded rod 91. One side of the movable block 92 is fixedly connected to the outside of the pressure plate 7. A turntable 93 is fixed to the top of the threaded rod 91. The threaded rod 91 is vertically arranged on the outside of the limiting plate 2 and threadedly connected to the inner wall of the movable block 92. By rotating the threaded rod 91, the movable block 92 can be driven to move up and down along the inner wall of the limiting plate 2. The movable block 92 is slidably connected to the inner wall of the limiting plate 2 and fixedly connected to the outside of the pressure plate 7. Under the rotation of the threaded rod 91, the rotational motion is converted into linear motion, which drives the pressure plate 7 to move up and down, thereby realizing the pressing or releasing of the silicone rubber material. The turntable 93 is fixed to the top of the threaded rod 91, which makes it easy for the operator to rotate the threaded rod 91, thereby controlling the movement of the pressure plate 7.

[0028] A vertically arranged support plate 10 is fixed to the inner wall of the base 1. Two sets of sliding rods 11 are fixed to both sides of the support plate 10, and the outer sides of the sliding rods 11 are slidably connected to the inner wall of the movable plate 62. Mounting blocks 12 are fixed to both sides of the movable plate 62, and pull rods 13 are fixed to the outer sides of the mounting blocks 12. Fixing seats 14 are fixed to both sides of the mounting blocks 12. A first fixing bolt 15 is fixed to one side of the fixing seat 14, and a snap-fit ​​plate 16 is slidably connected to the outer side of the first fixing bolt 15. Sliding rods 16 are provided on both sides of the mounting blocks 12. The slide rail 17 is slidably connected to the inner wall of the locking plate 16. The support plate 10 is fixed to the inner wall of the base 1, providing an installation position for the slide rod 11 and enhancing the structural stability of the entire locking mechanism 6. The slide rod 11 is slidably connected to the inner wall of the movable plate 62, guiding the movement of the movable plate 62 and ensuring that the movable plate 62 can move smoothly and accurately left and right, making the locking of the hook 63 and the base plate 4 more reliable. The mounting block 12 is fixed on both sides of the movable plate 62, providing support for components such as the pull rod 13 and the fixed seat 14. The installation position allows the operator to control the movement of the movable plate 62 by pulling the lever 13. The lever 13 is fixed to the outside of the mounting block 12. The operator can pull the lever 13 to overcome the elastic force of the spring 61, causing the movable plate 62 to move outward, thereby separating the hook 63 from the base plate 4, facilitating the disassembly and replacement of the base plate 4. The fixing seat 14 is fixed to both sides of the mounting block 12, providing an installation position for the first fixing bolt 15. A snap-fit ​​plate 16 is slidably connected to the outside of the first fixing bolt 15 to restrict the snap-fit ​​plate 16. The direction of movement is such that it can only slide along the axial direction of the first fixing bolt 15. Under the action of the slide rail 17, the snap-fit ​​plate 16 can slide along both sides of the mounting block 12. When the pull rod 13 is pulled to separate the hook 63 from the base plate 4, the snap-fit ​​plate 16 can be slid to the pull rod 13 to lock the pull rod 13, so that the movable plate 62 is kept in the separated state. The slide rail 17 is set on both sides of the mounting block 12 and is slidably connected to the inner wall of the snap-fit ​​plate 16. It plays a guiding role in the sliding of the snap-fit ​​plate 16, ensuring that the snap-fit ​​plate 16 can slide smoothly and accurately.

[0029] Two sets of symmetrically designed limiting rods 18 are fixed on one side of the movable block 92, and the outer side of the limiting rod 18 is slidably connected to the inner wall of the limiting plate 2. A second fixing bolt 19 is fixed to one end of the limiting rod 18. The limiting rod 18 is fixed to one side of the movable block 92, is symmetrically designed, and is slidably connected to the inner wall of the limiting plate 2. It guides and limits the movement of the movable block 92, prevents the movable block 92 from deflecting or shaking during the movement, and ensures that the pressure plate 7 can move smoothly and accurately. The second fixing bolt 19 is fixed to one end of the limiting rod 18 and can be used to limit the movement range of the limiting rod 18 to prevent the movable block 92 from moving excessively and detaching from the limiting plate 2.

[0030] Working principle: When coating the silicone rubber material, the base plate 4 is first placed on top of the base 1, so that the inner wall of the base plate 4 is inserted into the outer side of the positioning block 3, achieving initial positioning of the base plate 4. At this time, the spring 61 in the locking mechanism 6 is in its natural state. Under the elastic force of the spring 61, the movable plate 62 keeps the hook 63 in the appropriate position. After the base plate 4 is in place, the elastic force of the spring 61 pushes the movable plate 62 to move, causing the hook 63 to engage with the inner wall of the base plate 4, thereby fixing the base plate 4 to the base 1. Above, the sliding rods 11 on both sides of the support plate 10 are slidably connected to the inner wall of the movable plate 62, guiding the movement of the movable plate 62 and ensuring that the hook 63 can accurately and smoothly engage with the base plate 4. Then, the silicone rubber material to be coated is placed above the base plate 4. After that, the turntable 93 in the moving mechanism 9 is rotated, and the turntable 93 drives the threaded rod 91 to rotate. Since the inner wall of the movable block 92 is threadedly connected to the outer side of the threaded rod 91, and the movable block 92 slides on the inner wall of the limiting plate 2, while the limiting rod 18 slides on the inner wall of the limiting plate 2 to guide and limit, the rotation of the threaded rod 91 will cause the movable block 92 to move downward along the inner wall of the limiting plate 2. The downward movement of the movable block 92 drives the pressure plate 7 fixedly connected to it to move downward until the second pad 8 at the bottom of the pressure plate 7 engages with the first pad 5 at the top of the base plate 4, pressing the silicone rubber material placed on the base plate 4 to ensure that the silicone rubber material remains stable during the coating process and to prevent displacement or deformation. When it is necessary to remove the base plate 4, simply pull the outer side of the mounting block 12. The pull rod 13 on the side overcomes the elastic force of the spring 61, causing the movable plate 62 to move outward, which in turn causes the hook 63 to separate from the inner wall of the base plate 4. At the same time, the snap-fit ​​plate 16 slides along the slide rail 17 to the pull rod 13, snapping the pull rod 13 and keeping the movable plate 62 in the separated state. At this time, the base plate 4 can be easily removed from the base 1. Then, the operation is reversed. The snap-fit ​​plate 16 is removed, and the elastic force of the spring 61 will cause the movable plate 62 to return to its original position. The hook 63 is once again in the snap-fit ​​position, preparing for the next installation of the base plate 4.
