Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation films, and in particular to a heat dissipation film laminating device and process. Background Art

[0002] Heat dissipation film is a structural component used under the mobile phone screen. Due to the market's increasing requirements for the display functions and functions of mobile phone screens, the heat dissipation film structure changes with market demand. SUS heat dissipation film is a heat dissipation film that not only handles heat dissipation but also has a strong supporting structure. Because the thickness of SUS is 0.1mm and the hardness reaches 380HV, there will be serious burrs and burrs (above 0.2mm) when the equipment cuts SUS. The burrs will cause the screen to pierce, so the die-cutting process and equipment cannot meet the process requirements of SUS heat dissipation film products. New processes and equipment are needed to meet the product structure and market demand.

[0003] The existing technology has the following problems in the processing of SUS heat dissipation film:

[0004] During the die-cutting process, the hardness of 0.1mm SUS reaches 380HV, and the die blade of the die-cutting process is relatively fragile. Even if the hardness of the imported steel is only HRC65 after heat treatment, a die will be damaged after processing thousands of pieces. In addition, the cost is expensive. Combined with the complex die-cutting process, the cost of frequent die replacement and machine adjustment is very high.

[0005] In the manual assembly process, the SUS is etched, the other layers are processed by die-cutting, and finally the parts are assembled manually using jigs. Because the product requires high assembly precision, the manual assembly efficiency of multiple people is less than 100 PCS per hour, and the defective assembly rate caused by manual labor is high.

[0059] The present invention provides a heat dissipation film 400 bonding device. In the prior art, due to the high precision requirements for the assembly and bonding of the heat dissipation film 400, a lot of manual bonding is used, which is inefficient. In order to solve the above technical problems, the present invention optimizes the equipment, reduces manual bonding, and improves the accuracy of bonding, thereby achieving the purpose of improving bonding efficiency and quality.

[0060] As shown in the figure, the heat dissipation film 400 provided by the present invention includes a copper foil graphite layer 410, a SUS steel sheet 420 layer and a protective film 430 layer and is bonded from bottom to top, wherein the copper foil graphite layer 410 is composed of integrated foam glue, PET single-sided tape, graphite, double-sided tape, and copper foil bonded from bottom to top; the protective film 430 is composed of marking tape and protective film 430 bonded together.

[0061] The copper foil graphite layer 410 , the protective film 430 and the SUS steel sheet 420 are all prepared by different die-cutting and laminating processes and then laminated by laminating equipment to form the heat dissipation film 400 .

[0062] The heat dissipation film 400 laminating equipment mainly includes a first conveying mechanism 100, a second conveying mechanism 300 and a transport mechanism 200, wherein the transport mechanism 200 is used to transport the material from the second conveying mechanism 300 to the first conveying mechanism 100 for lamination. Figure 1-3 As shown in the figure, there are two second conveying mechanisms 300, which are independent of each other, so that there are also two matching transport mechanisms 200. As shown in the figure, the first conveying mechanism 100, the second conveying mechanism 300 and the transport mechanism 200 are all set on a bracket, and a workbench is set on the bracket to install the mechanism.

[0063] The structure of the first conveying mechanism 100 is now described in detail;

[0064] The first conveying mechanism 100 mainly includes a traction belt 001, which is driven by a traction motor. Specifically, a traction roller is provided on the output shaft sleeve of the traction motor, and the traction belt 001 is arranged between the traction rollers so that the traction belt 001 can be continuously conveyed forward.

[0065] The second conveying mechanism 300 for conveying the SUS steel sheet 420 mainly includes a traction belt 001. A traction roller is provided at the bottom of the traction belt 001. The traction roller is driven by a traction motor to convey the traction belt 001. Under the action of the traction belt 001, the SUS steel sheet 420 can be conveyed synchronously with the traction belt 001. The SUS steel sheet 420 is a Z-shaped belt and is placed at one end of the traction belt 001. In the process of conveying the SUS steel sheet 420, two stripping knives 003 are also provided to peel off the upper cover film and the bottom film of the SUS steel sheet 420 respectively, wherein the upper cover film is wound by a winding shaft provided above the traction belt 001. 002 is wound up, and the upper cover film is peeled off by the first peeling knife 003. After peeling, the SUS steel sheet 420 continues to be transported, and the SUS steel sheet 420 is sucked to a certain height by the suction cup 210 of the conveying mechanism 200. At this time, the bottom film is peeled off by the second peeling knife 003. Specifically, a return cylinder is provided on the frame. The operation is that the return cylinder drives the second peeling knife 003 to move toward the bottom of the SUS steel sheet 420 and peel off the bottom film. After peeling, it returns to its original position, and the peeled bottom film is wound up by the waste collection shaft 004, and the steel sheet continues to stay on the suction cup 210 for the next operation. The specific operation is performed by the conveying mechanism 200.

[0066] As shown in the figure, the second conveying mechanism 300 for conveying the protective film 430 and the second conveying mechanism 300 for conveying the SUS steel sheet 420 are symmetrically installed on the side of the first conveying mechanism 100. In addition to the above installation method, the two second conveying mechanisms 300 can also be installed in parallel. After parallel installation, they are perpendicular to the first conveying mechanism 100. The specific installation position can be designed according to actual conditions. No excessive restrictions are made here. This application takes the symmetrical installation method in the figure as an example for explanation.

[0067] The second conveying mechanism 300 for conveying the protective film 430 layer mainly includes a traction belt 001, a traction roller is provided at the bottom of the traction belt 001, and the traction roller is driven by a traction motor to convey the traction belt 001. Under the action of the traction belt 001, the protective film 430 layer can be conveyed synchronously with the traction belt 001. The protective film 430 layer is initially placed on the unwinding shaft 006 and placed on one end of the traction belt 001. In the process of conveying the protective film 430 layer, two peeling knives 003 are also provided to peel off the upper cover film and the bottom film of the protective film 430 layer respectively, wherein the upper cover film is peeled off by setting it above the traction belt 001. The reel 002 is reeled in, and the upper cover film is peeled off by the first peeling knife 003. After peeling, the protective film 430 layer continues to be transported, and the protective film 430 layer is sucked to a certain height by the suction cup 210 of the conveying mechanism 200. At this time, the bottom film is peeled off by the second peeling knife 003. Specifically, a return cylinder is provided on the frame. The operation is that the return cylinder drives the second peeling knife 003 to move toward the bottom of the protective film 430 layer and peel off the bottom film. After peeling, it returns to its original position, and the peeled bottom film is reeled in by the waste collecting shaft 004, and the steel sheet continues to remain on the suction cup 210 for the next operation. The specific operation is performed by the conveying mechanism 200.

[0068] The main material conveyed by the first conveying mechanism 100 is the copper foil graphite layer 410. Specifically, a reeling shaft 006 with a copper foil graphite layer 410 coil is provided on the bracket. Under the action of the traction material belt 001, the copper foil graphite layer 410 can be conveyed forward synchronously with the traction hopper. During the conveying process, a top cover film for peeling off the copper foil graphite layer 410 is also provided on the workbench. The top cover film is wound by the reeling shaft 002, and the peeling of the top cover film is performed by a peeling knife.

[0069] The traction belt 001, unwinding shaft 006, rewinding shaft 002 and waste collection shaft 004 of the above-mentioned first conveying mechanism 100 and second conveying mechanism 300 are all independent structures, and each mechanism corresponds to a set, so that it can perform operations such as peeling and rewinding the cover film of different materials.

[0070] The transporting mechanism 200 for transporting the SUS steel sheet 420 mainly includes a longitudinal moving fixed frame 221 arranged on the bracket, and a slide rail 222 is provided on the longitudinal moving fixed frame 221, and a longitudinal moving slider 223 is slidably fitted on the slide rail 222. The driving cylinder 224 is connected to the side wall of the longitudinal moving slider 223, and the telescopic end of the driving cylinder 224 is connected to the suction cup 210. The longitudinal moving slider 223 enables the suction cup 210 to move in the longitudinal direction. Under the telescopic action of the driving cylinder 224, the suction cup 210 can move in the vertical direction. The telescopic action of the driving cylinder 224 enables the suction cup 210 to absorb the SUS steel sheet 420. The longitudinal moving slider 223 enables the suction cup 210 to drive the SUS steel sheet 420 to be transported in the direction of the first conveying mechanism 100. The power of the longitudinal moving slider 223 comes from the driving motor, and the driving motor drives the longitudinal moving slider 223 to move in the slide rail 222.

[0071] In the process of sucking and transferring the SUS steel sheet 420 to the copper foil graphite layer 410 for bonding, in order to ensure the accuracy of bonding, a positioner 230 and a correction component are further set up. The positioner 230 is selected as a positioning CCD camera. There are two positioners 230, which are located on the longitudinal fixed frame 221 and are arranged above the traction belt 001 of the first conveying mechanism 100, specifically above the bonding part, and can take pictures and locate the copper foil graphite layer 410 placed on the traction belt 001, and collect and process its information.

[0072] The correction component is located between the first conveying mechanism 100 and the second conveying mechanism 300. As shown in the figure, the correction component includes two correctors 240, which are correction CCD cameras. The two correction CCD cameras are arranged side by side to take pictures of the SUS steel sheet 420, collect information after taking pictures, and compare it with the information of the positioning CCD camera, so that a more accurate fitting position can be obtained.

[0073] The traction belt 001 of the first conveying mechanism 100 is divided into a conveying part and a bonding part, wherein the conveying part is mainly used to convey the copper foil graphite layer 410. There are two bonding parts, one of which is to bond the SUS steel sheet 420 to the copper foil graphite layer 410 to form a semi-finished product, and the other bonding part is to bond the protective film 430 on the semi-finished product to form a heat dissipation film 400.

[0074] When bonding the SUS steel sheet 420, the bonding component 110 is arranged below the traction belt 001. The bonding component 110 mainly includes a transverse frame 113. An upper cylinder 111 is provided on the transverse frame 113. The telescopic end of the upper cylinder 111 is provided with a bubble-exhausting bonding roller 112. Driven by the upper cylinder 111, the bubble-exhausting bonding roller 112 is brought into contact with and pressed against the traction belt 001, thereby bonding the SUS steel sheet 420 and the copper foil graphite layer 410.

[0075] The bonding equipment also includes a skip-step stop optical fiber. During operation, when the current SUS steel sheet 420 is bonded, the skip step is completed through the skip-step stop optical fiber induction, and the next SUS steel sheet 420 is bonded again, and the cycle continues.

[0076] When laminating the protective film 430, the laminating component 110 is set on the side wall of the suction cup 210. Driven by the lower top cylinder 115, the bubble-exhausting laminating roller 112 is brought into contact with the protective film 430, and then the suction cup 210 is driven by the motor to move in the longitudinal direction, so that the bubble-exhausting laminating roller 112 presses the protective film 430 to complete the laminating.

[0077] This bonding equipment also includes a skip-step stop optical fiber. During operation, when the current protective film 430 is bonded, the skip step is completed through the skip-step stop optical fiber sensing, and the next protective film 430 is bonded again, and the cycle is repeated. The skip-step stop optical fiber belongs to the existing technology, and the skip step can be completed, so it will not be elaborated on here.

[0078] After lamination, the heat dissipation film 400 continues to be transported under the action of the traction belt 001, and the heat dissipation film 400 is rolled up by the roller.

[0079] The present invention is provided with a first conveying mechanism 100 and a second conveying mechanism 300. The first conveying mechanism 100 conveys the copper foil graphite layer 410. There are two second conveying mechanisms 300, one of which conveys the SUS steel sheet 420 and the other conveys the protective film 430. A conveying mechanism 200 is also provided to convey the SUS steel sheet 420 conveyed by the second conveying mechanism 300 to the copper foil graphite layer 410 of the first conveying mechanism 100 and laminate them to form a semi-finished product. The other second conveying mechanism 300 conveys the protective film 430 to the first conveying mechanism 100 and laminates it to the semi-finished product to form a heat dissipation film 400. The first conveying mechanism 100 and the two second conveying mechanisms 300 convey them separately at the same time and laminate them synchronously to obtain the heat dissipation film 400.
