Description

A bubble-removing device for SUS and double-sided tape Technical Field

[0001] This utility model relates to the technical field of bubble removal equipment, specifically a bubble removal device for SUS and double-sided tape. Background Technology

[0002] In the die-cutting industry, the bonding of SUS stainless steel sheets with adhesive backing is a critical process, and its quality and efficiency directly affect the performance and reliability of downstream products in electronics, automobiles, and medical devices. In the field of electronic equipment manufacturing, with the rapid development of 5G and IoT technologies, devices such as smartphones and tablets are becoming increasingly thinner and more integrated. SUS stainless steel sheets, as a core material for components such as casings and shielding covers, need to be tightly bonded with double-sided adhesive to achieve functions such as waterproofing, dustproofing, and electromagnetic shielding.

[0003] Traditionally, stainless steel sheets are mostly formed by stamping or etching before being bonded with adhesive using a laminating machine. However, air bubbles between the double-sided adhesive and the stainless steel sheet cannot be completely avoided during this process, resulting in a low yield. Therefore, those skilled in the art have provided an air bubble elimination device for SUS and double-sided adhesive to solve the problems mentioned in the background art. Summary of the Invention

Slider is connected to the other side of both the hard anilox roller and the elastic rubber roller.

[0008] As a further embodiment of this utility model: a first guide rod is fixedly connected inside the work frame, and the slider is slidably connected to the first guide rod. An electric push rod is fixedly connected to the top of the work frame and to the side of the hard anilox roller away from the first guide roller, and a contact sensor is fixedly connected to the bottom of the electric push rod.

[0009] As a further embodiment of this utility model: a third guide roller is provided inside the work frame and on the side away from the second guide roller from the electric push rod, and a traction roller is provided inside the work frame and on the side away from the electric push rod from the third guide roller.

[0010] As a further embodiment of this utility model: the steel plate fixing structure includes a positioning platform, a stainless steel plate, a first threaded rod, a second guide rod, a second threaded sleeve, a clamping block, and a second motor. The positioning platform is fixedly connected to the bottom of the work frame on the side of the elastic rubber roller away from the second guide roller. The first threaded rods are rotatably connected to both sides of the positioning platform, and the threads of the two first threaded rods are opposite. The second motor is fixedly connected to the top of the work frame on the side of the two first threaded rods away from each other, and the output end of the second motor is fixedly connected to the first threaded rod.

[0011] As a further embodiment of this utility model: a second guide rod is fixedly connected to both sides of the positioning platform, and a second threaded sleeve is threadedly connected to the first threaded rod. The second threaded sleeve is L-shaped, and a clamping block is fixedly connected to one end of each of the two second threaded sleeves that are close to each other. A stainless steel plate is placed on the top of the positioning platform, and the clamping block is in contact with the stainless steel plate.

[0012] As a further embodiment of this utility model: the bubble elimination structure includes a fixed box, a third motor, a second threaded rod, a third guide rod, a third threaded sleeve, and a rubber bonding roller. The fixed box is fixedly connected inside the work frame and above the positioning platform. The third motor is fixedly connected inside the fixed box. The second threaded rod is rotatably connected to one side of the fixed box and is fixedly connected to the output end of the third motor. The third guide rod is fixedly connected to one side of the fixed box. The third threaded sleeve is threadedly connected to the second threaded rod, and the rubber bonding roller is rotatably connected inside the third threaded sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This device completes the mesh forming operation of double-sided adhesive by setting a mesh forming structure. The first motor drives the positive and negative lead screws to rotate, which drives the two first threaded sleeves to move closer to each other. The two first threaded sleeves drive the hard mesh roller and the elastic rubber roller connected to them to move. When the hard mesh roller and the elastic rubber roller move to the appropriate position, they squeeze the conveyed mesh release film and double-sided adhesive in the middle. Under the pressure of the two rollers, the mesh pattern on the surface of the mesh release film is imprinted onto the double-sided adhesive, completing the mesh forming, so that the die-cut double-sided adhesive forms a surface texture before bonding.

[0015] 2. This device uses a steel plate fixing structure to fix the stainless steel plate. The second motor drives the first threaded rod to rotate, which in turn drives the two second threaded sleeves to move closer or further apart. The second threaded sleeves drive the clamping block connected to them to gradually move closer to the stainless steel plate until the stainless steel plate is firmly clamped on the positioning platform, ensuring that the stainless steel plate remains stable and does not shift during the subsequent bonding process.

[0016] 3. This device eliminates air bubbles between the double-sided adhesive and the stainless steel plate through an air bubble elimination structure. A third motor drives the second threaded rod to rotate, which in turn moves the third threaded sleeve, causing the rubber bonding roller to roll from one end of the stainless steel plate to the other. During the rolling process, the rubber bonding roller uses its own elasticity to evenly press the textured double-sided adhesive onto the stainless steel plate. Because the texture on the surface of the double-sided adhesive forms air channels, air bubbles between the double-sided adhesive and the stainless steel plate are squeezed out along the textured air channels under the pressure of the rubber bonding roller. After the rubber bonding roller rolls to the other end of the stainless steel plate, it can be rolled in the opposite direction as needed to further ensure that the air bubbles are completely eliminated, achieving a tight, bubble-free, high-quality bond between the SUS and the double-sided adhesive.

[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] Example 1: Referring to Figures 1-2, this example provides a bubble elimination device for SUS and double-sided adhesive, including a work frame 1, a textured forming structure, a steel plate fixing structure, and a bubble elimination structure. The work frame 1 is characterized by the following features: a textured release film unwinding roller 2 is rotatably connected inside the work frame 1; several first guide rollers 3 are rotatably connected inside the work frame 1 and on one side of the textured release film unwinding roller 2; a double-sided adhesive unwinding roller 4 is rotatably connected inside the work frame 1 and directly below the textured release film unwinding roller 2; several second guide rollers 5 are rotatably connected inside the work frame 1 and on one side of the double-sided adhesive unwinding roller 4; a textured forming structure is provided inside the work frame 1 on the side of the second guide rollers 5 away from the double-sided adhesive unwinding roller 4; a steel plate fixing structure is provided at the bottom of the work frame 1 on the side of the textured forming structure away from the second guide rollers 5; and a bubble elimination structure is provided inside the work frame 1 and above the steel plate fixing structure.

[0024] The anilox forming structure includes a first motor 6, a forward and reverse lead screw 7, a first threaded sleeve 8, a first guide rod 9, a slider 10, a rigid anilox roller 11, an elastic rubber roller 12, an electric push rod 13, and a contact sensor 14. The first motor 6 is fixedly connected to the bottom of the work frame 1. The forward and reverse lead screw 7 is rotatably connected to the top of the work frame 1, and two first threaded sleeves 8 are threadedly connected to the forward and reverse lead screw 7. The rigid anilox roller 11 is rotatably connected to one side of one first threaded sleeve 8, and the elastic rubber roller 12 is rotatably connected to one side of the other first threaded sleeve 8. The slider 10 is connected to the other side of both the rigid anilox roller 11 and the elastic rubber roller 12. The first guide rod 9 is fixedly connected to the inside of the work frame 1, and the slider 10 is slidably connected to the first guide rod 9. The electric push rod 13 is fixedly connected to the top of the inside of the work frame 1, on the side of the rigid anilox roller 11 away from the first guide roller 3, and the contact sensor 14 is fixedly connected to the bottom of the electric push rod 13.

[0025] A third guide roller 15 is provided inside the work frame 1 and on the side of the electric push rod 13 away from the second guide roller 5. A traction roller 16 is provided inside the work frame 1 and on the side of the third guide roller 15 away from the electric push rod 13.

[0026] The textured release film unwinding roller 2, the double-sided adhesive unwinding roller 4, and the traction roller 16 are all connected to an external drive motor.

[0027] In this implementation, the textured release film is mounted on the textured release film unwinding roller 2, and the die-cut double-sided adhesive is mounted on the double-sided adhesive unwinding roller. Then, an external drive motor drives the textured release film unwinding roller 2 and the double-sided adhesive unwinding roller 4 to rotate respectively. The textured release film is released from the unwinding roller 2 and, guided by the first guide roller 3, moves smoothly along a fixed path. The die-cut double-sided adhesive is released from the unwinding roller 4 and guided by the second guide roller 5, maintaining parallel and synchronous transport with the textured release film. Both move together toward the textured forming structure. During this process, several guide rollers play a role in limiting and stabilizing the transport path. The diameter ensures that the material does not shift or wrinkle. Then, the first motor 6 is started to drive the positive and negative lead screws 7 to rotate. Since there are two first threaded sleeves 8 connected to the positive and negative lead screws 7 with opposite thread directions, the two first threaded sleeves 8 will move towards or in opposite directions on the positive and negative lead screws 7. When the first threaded sleeves 8 move, they respectively drive the hard anilox roller 11 and the elastic rubber roller 12 connected to them to move. At the same time, the slider 10 slides on the first guide rod 9 to provide guidance and stable support for the movement of the hard anilox roller 11 and the elastic rubber roller 12, preventing them from shifting. When the hard anilox roller 11 and the elastic rubber roller 12 move, the slider 10 slides on the first guide rod 9 to provide guidance and stable support for the movement of the hard anilox roller 11 and the elastic rubber roller 12, preventing them from shifting. The elastic rubber roller 12 moves to a suitable position, bringing the two rollers close together and pressing the conveyed textured release film and double-sided adhesive together. Under the pressure of the two rollers, the textured surface of the release film is imprinted onto the double-sided adhesive, completing the texture forming. This creates a surface texture on the die-cut double-sided adhesive before lamination. After texture forming, the electric push rod 13 is activated, pushing the contact sensor 14, which is fixedly connected to the bottom, to descend and contact the textured surface of the double-sided adhesive. The contact sensor 14 can detect parameters such as the depth and flatness of the texture on the double-sided adhesive and feed the data back to the equipment control system. If the detected parameters meet the preset standards, the electric push rod 13 retracts, driving the contact sensor 14 to rise and reset, and the equipment continues to operate. If the standards are not met, the control system issues a command, the first motor 6 reverses, causing the rigid anilox roller 11 and the elastic rubber roller 12 to separate. After adjusting the pressure or spacing, the anilox forming and detection are performed again until the anilox meets the requirements. Then, the traction roller 16 is driven by an external drive motor to pull the double-sided adhesive and anilox release film assembly that has completed the anilox forming from the rigid anilox roller 11 and the elastic rubber roller 12, and continue to transport it to the subsequent process.

[0028] Example 2: Referring to Figures 1 and 3, this example is based on the previous example, but differs in that the steel plate fixing structure includes a positioning platform 17, a stainless steel plate 18, a first threaded rod 19, a second guide rod 20, a second threaded sleeve 21, a clamping block 22, and a second motor 23. The positioning platform 17 is fixedly connected to the bottom of the work frame 1 on the side of the elastic rubber roller 12 away from the second guide roller 5. The first threaded rod 19 is rotatably connected to both sides of the positioning platform 17, and the threads of the two first threaded rods 19 are opposite. The second motor 23 is fixedly connected to the top of the work frame 1 on the side of the two first threaded rods 19 away from each other, and the output end of the second motor 23 is fixedly connected to the first threaded rod 19.

[0029] The positioning platform 17 has two guide rods 20 fixedly connected to both side walls, and a second threaded sleeve 21 is threadedly connected to the first threaded rod 19. The second threaded sleeve 21 is L-shaped, and a clamping block 22 is fixedly connected to one end of each of the two second threaded sleeves 21. A stainless steel plate 18 is placed on the top of the positioning platform 17, and the clamping block 22 is in contact with the stainless steel plate 18.

[0030] In this embodiment, the stainless steel plate 18 is placed on the positioning platform 17, and the second motor 23 is started. Its output end drives the first threaded rod 19 to rotate. Because the threads of the two first threaded rods 19 are opposite, the L-shaped second threaded sleeves 21, which are respectively threaded onto the two first threaded rods 19, will move towards each other along the threaded rods. During the movement of the second threaded sleeves 21, the second guide rod 20 plays an auxiliary guiding role to ensure that it moves smoothly and does not deviate. As the second threaded sleeves 21 move, the clamping block 22 connected to it gradually approaches the stainless steel plate 18 until the stainless steel plate 18 is firmly clamped on the positioning platform 17, ensuring that the stainless steel plate 18 remains stable during the subsequent bonding process and does not shift.

[0031] Example 3: Referring to Figures 1 and 4, this example is based on the previous example, but differs in that the bubble elimination structure includes a fixed box 24, a third motor 25, a second threaded rod 26, a third guide rod 27, a third threaded sleeve 28, and a rubber bonding roller 29. The fixed box 24 is fixedly connected inside the work frame 1 and above the positioning platform 17. The third motor 25 is fixedly connected inside the fixed box 24, and the second threaded rod 26 is rotatably connected to one side of the fixed box 24. The second threaded rod 26 is fixedly connected to the output end of the third motor 25. The third guide rod 27 is fixedly connected to one side of the fixed box 24, and the third threaded sleeve 28 is threadedly connected to the second threaded rod 26. The rubber bonding roller 29 is rotatably connected inside the third threaded sleeve 28.

[0032] In this embodiment, the third motor 25 inside the fixed box 24 is activated to drive the second threaded rod 26 to rotate. The third threaded sleeve 28 is threadedly connected to the second threaded rod 26. As the second threaded rod 26 rotates, the third threaded sleeve 28 moves along the second threaded rod 26. At the same time, the third guide rod 27 provides guidance for the movement of the third threaded sleeve 28, ensuring its smooth and accurate movement. When the third threaded sleeve 28 moves, it drives the internally rotatably connected rubber bonding roller 29 to move. The rubber bonding roller 29 starts from one end of the stainless steel plate 18. As it rolls to the other end, the rubber bonding roller 29 uses its own elasticity to evenly press the textured double-sided adhesive onto the stainless steel plate 18. Since the textured surface of the double-sided adhesive forms air channels, under the pressure of the rubber bonding roller 29, the air bubbles between the double-sided adhesive and the stainless steel plate 18 will be squeezed out along the textured air channels. After the rubber bonding roller 29 rolls to the other end of the stainless steel plate 18, it can be rolled in the opposite direction again as needed to further ensure that the air bubbles are completely eliminated, thus achieving a tight, bubble-free, high-quality bond between the SUS and the double-sided adhesive.
