Description

Technical Field

[0001] This invention relates to the field of coating technology, and in particular to a coating machine for the production of display modules. Background Technology

[0002] As people's living standards continue to improve, electronic devices have become indispensable products in people's daily lives and work. The display screen of electronic devices is made by bonding the display module and the cover plate together with adhesive. After the display module is manufactured, a protective film is applied to the surface of the display module using a laminating machine to protect it.

[0003] Compared with existing technologies in related fields, it can be seen that when laminating, most laminating machines cut off the excess protective film with a cutter after lamination. The cutting process requires high precision, and cutting deviations can easily damage the display module. Furthermore, the cutting process can easily cause the edges of the protective film to wrinkle due to stress, affecting the quality of lamination. Summary of the Invention

[0004] The purpose of this invention is to provide a laminating machine for the production of display modules in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A laminating machine for display module production includes a laminating table, on which are provided a cutting unit for cutting protective film, a film feeding mechanism for conveying protective film, a base and a support. The base is equipped with a clamping unit for fixing materials and a feeding mechanism for conveying materials. The support is equipped with a displacement unit for adjusting position, a lifting unit for adjusting height, and a laminating unit for installing protective film. The coating unit includes a mounting base, which is mounted on a lifting unit. A bidirectional adjustment assembly is mounted on the mounting base, and two first sliders are mounted on the bidirectional adjustment assembly. Each of the two first sliders is equipped with a blower pipe. The bidirectional adjustment assembly includes a bidirectional screw and a first motor. The first motor is mounted on the mounting base, and the bidirectional screw is rotatably mounted on the mounting base. The bidirectional screw is connected to the output shaft of the first motor. The two ends of the bidirectional screw have opposite thread directions, and the two ends of the bidirectional screw are respectively threaded to the first sliders. The first sliders are slidably connected to the mounting base. The lower surfaces of both ends of the mounting base are provided with second air holes. The mounting base is provided with a first connecting valve and a second connecting valve. The first connecting valve is connected to the second air hole. The blower pipe is provided with first air holes at equal intervals, and the blower pipe is connected to the second connecting valve. The cutting unit on the laminating table includes a lifting drive mechanism, which is installed on the lower surface of the laminating table. A placement frame is installed on the lifting drive mechanism, which corresponds to the film placement mechanism. A second hydraulic cylinder is installed at an equal angle on the placement frame, and a cutter is installed on the telescopic end of the second hydraulic cylinder. The displacement unit on the bracket includes a second motor and a lead screw. The second motor is mounted on the bracket, and the lead screw is rotatably connected to the bracket. The lead screw is connected to the output shaft of the second motor, and a second slider is threaded onto the lead screw. The second slider is slidably connected to the bracket and to the lifting unit.

[0006] Furthermore, the lifting unit includes a support frame, which is mounted on the second slider. A first hydraulic cylinder is mounted on the support frame, and a fixing plate is mounted on the telescopic end of the first hydraulic cylinder. The fixing plate is connected to the mounting base.

[0007] Furthermore, the clamping unit on the base includes a third hydraulic cylinder, which is installed on both sides of the base. A material-lifting assembly is installed on the telescopic end of the third hydraulic cylinder, and the material-lifting assembly is slidably connected to the material conveying mechanism.

[0008] Furthermore, the top-loading assembly on the third hydraulic cylinder includes a receiving seat, which is installed on the telescopic end of the third hydraulic cylinder. Bolts are installed on the receiving seat, and a stop bar is slidably installed on the receiving seat. The stop bar is L-shaped and connected by bolts.

[0009] Furthermore, the base has grooves on both sides inside, and a guide rod is rotatably connected to the end of the storage seat away from the stop bar, with the guide rod slidably connected to the groove.

[0010] Furthermore, a photoelectric sensor is installed on the stop lever.

[0011] Furthermore, protective pads are installed on the storage base, stop bar, and guide rod.

[0012] Furthermore, distance sensors are installed on both sides of the lower surface of the mounting base.

[0013] The advantages compared to existing technologies are as follows: 1. The protective film is cut to the same size as the display module by a lifting drive mechanism, a second hydraulic cylinder, and a cutter. An external air extraction device adsorbs and fixes the cut protective film through a first connecting valve and a second air hole. The second motor, lead screw, and second slider drive the mounting base and the protective film to move. The protective film is adhered to the display module through a blower pipe and a first air hole. The protective film is cut before being applied, thus protecting the display module during the application process and preventing collision damage caused by cutting after application. The flexible pressing of the air jet through the first air hole presses and fixes the protective film on the display module, preventing wrinkles at the edges of the protective film, improving the quality of the application, and effectively preventing damage to the display module during the application process.

[0014] 2. The conveyed display module is guided by the guide rod, and the display module is positioned and clamped by the third hydraulic cylinder, the storage seat and the stop bar, which effectively prevents the display module from moving during the film coating process, so as to better perform the film coating and improve the quality of film coating.

The support 14 is equipped with a displacement unit 5 for adjusting position, a lifting unit 3 for adjusting height, and a laminating unit 2 for installing the protective film. The film feeding mechanism 13 and the conveying mechanism 12 employ existing technologies during operation, such as... Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, the display module is conveyed to the film coating position by the feeding mechanism 12, the display module is clamped and fixed by the clamping unit, the protective film is placed on the film roll by the film feeding mechanism 13, the protective film is cut into the same size as the display module by the cutting unit, the displacement unit 5 moves the cut protective film to the top of the display module by the film coating unit 2, and the protective film is attached to the display module by the film coating unit 2 to complete the film coating of the display module; The coating unit 2 includes a mounting base 21, which is mounted on the lifting unit 3.

The first connecting valve 28 connects to an external air extraction device, and the second connecting valve 29 connects to an external air supply device. Figure 1 , Figure 5As shown, the lifting unit 3 drives the mounting base 21 to move, so that the mounting base 21 is attached to the cut protective film. The external air extraction device adsorbs and fixes the protective film through the first connecting valve 28 and the second air hole 26, thereby adsorbing the cut protective film onto the mounting base 21. The displacement component moves the mounting base 21 and the protective film above the display module through the lifting unit 3. The lifting unit 3 drives the mounting base 21 and the protective film to move close to the display module. The external air supply device blows air into the blower pipe 24 through the second connecting valve 29 and sprays it out through the first air hole 25. The sprayed gas blows the protective film on the mounting base 21, so that the protective film is attached to the display module, avoiding air bubbles during the film application. The gentle pressing of the air jet effectively avoids damage to the display module during the film application process. The bidirectional adjustment component drives the blower pipe 24 to move, thereby blowing air onto the entire protective film, so that the protective film is completely attached to the display module. The cutting unit on the laminating table 1 includes a lifting drive mechanism 41, which is mounted on the lower surface of the laminating table 1. A placement frame 42 is mounted on the lifting drive mechanism 41, corresponding to the film placement mechanism 13. A second hydraulic cylinder 43 is mounted at equal angles on the placement frame 42, and a cutter 44 is mounted on the telescopic end of the second hydraulic cylinder 43. The lifting drive mechanism 41 and the second hydraulic cylinder 43 are electrically connected to an external controller. The operation of the lifting drive mechanism 41 and the second hydraulic cylinder 43 utilizes existing technology. During operation, such as... Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, the second hydraulic cylinder 43 drives the cutter 44 to move, thereby moving the cutter 44 to different positions on the placement frame 42, so as to adjust the cutting size of the protective film according to the size of the display module. After the cutter 44 is adjusted, the lifting drive mechanism 41 drives the cutter 44 to move through the placement frame 42, and the cutter 44 cuts the protective film to the same size as the display module.

The first sliders 23 are slidably connected to the mounting base 21. The first sliders 23 at both ends of the bidirectional screw 22 are connected to the blower pipe 24. The first motor 27 is electrically connected to an external controller. The first motor 27 operates using existing technology. During operation, such as... Figure 1As shown, the first motor 27 drives the bidirectional screw 22 to rotate, the bidirectional screw 22 drives the first slider 23 to move, and the first slider 23 drives the blower pipe 24 to move, thereby adjusting the position of the blower pipe 24 so that the blower pipe 24 blows and flattens the protective film at different positions on the display module.

[0020] The displacement unit 5 on the bracket 14 includes a second motor 51 and a lead screw 52. The second motor 51 is mounted on the bracket 14, and the lead screw 52 is rotatably connected to the bracket 14. The lead screw 52 is connected to the output shaft of the second motor 51, and a second slider 53 is threaded onto the lead screw 52. The second slider 53 is slidably connected to the bracket 14 and connected to the lifting unit 3. The second motor 51 is electrically connected to an external controller. The second motor 51 operates using existing technology, such as... Figure 2 , Figure 6 , Figure 7 As shown, the second motor 51 drives the lead screw 52 to rotate, and the lead screw 52 drives the lifting unit 3 to move through the second slider 53, thereby moving the cut protective film to the film covering position.

[0021] The lifting unit 3 includes a support frame 31, which is mounted on the second slider 53. A first hydraulic cylinder 32 is mounted on the support frame 31. A fixing plate 33 is mounted on the telescopic end of the first hydraulic cylinder 32. The fixing plate 33 is connected to the mounting base 21. The first hydraulic cylinder 32 is electrically connected to an external controller. The first hydraulic cylinder 32 operates using existing technology, such as... Figure 2 , Figures 5-7 As shown, the mounting base 21 is installed and fixed by the fixing plate 33. During operation, the first hydraulic cylinder 32 drives the mounting base 21 to move through the fixing plate 33, thereby adjusting the height of the mounting base 21, which facilitates the coating of the display module.

[0022] The clamping unit on the base 11 includes a third hydraulic cylinder 61, which is mounted on both sides of the base 11. A material-lifting assembly 62 is mounted on the telescopic end of the third hydraulic cylinder 61. The material-lifting assembly 62 is slidably connected to the conveying mechanism 12. The third hydraulic cylinder 61 is electrically connected to an external controller. The operation of the third hydraulic cylinder 61 utilizes existing technology, such as... Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, the third hydraulic cylinder 61 drives the top material assembly 62 to clamp and fix the display module on the conveying mechanism 12, thereby enabling better film coating of the display module, avoiding film coating failure caused by movement of the display module during the film coating process, and improving the quality of film coating.

[0023] The top-loading assembly 62 on the third hydraulic cylinder 61 includes a receiving seat 6201, which is mounted on the telescopic end of the third hydraulic cylinder 61. Bolts 6203 are installed on the receiving seat 6201, and a stop rod 6202 is slidably mounted on the receiving seat 6201. The stop rod 6202 is L-shaped and connected to the bolts 6203. Figure 3 , Figure 6 As shown, the connection length between the storage base 6201 and the stop bar 6202 is adjusted according to the size of the display module, so that after the stop bar 6202 blocks the display module, the center position of the display module corresponds to the center position of the mounting base 21, thereby better positioning and coating the display module. The stop bar 6202 is L-shaped, which can block and clamp the coated display module. After the storage base 6201 and the stop bar 6202 are adjusted, the storage base 6201 and the stop bar 6202 are locked and fixed by bolts 6203, which improves the firmness and stability of the connection between the storage base 6201 and the stop bar 6202, improves the accuracy of positioning the display module, and thus better coating the display module.

[0024] The base 11 has sliding grooves 7 on both sides inside. A guide rod 8 is rotatably connected to the end of the storage base 6201 away from the stop bar 6202. The guide rod 8 is slidably connected to the sliding grooves 7. Figure 3 As shown, when the storage base 6201 clamps the display module, the storage base 6201 can drive the guide rod 8 to slide in the slide groove 7, thereby avoiding affecting the movement of the storage base 6201. The slide groove 7 and the storage base 6201 limit and guide the guide rod 8, and the guide rod 8 guides the display module on the conveying mechanism 12, avoiding the display module from deflecting during the conveying process, and facilitating the positioning and clamping of the conveyed display module.

[0025] A photoelectric sensor 10 is installed on the stop lever 6202. The photoelectric sensor 10 is electrically connected to an external controller. During operation, such as... Figure 3 As shown, the photoelectric sensor 10 detects whether the baffle 6202 is blocking the display module. When the photoelectric sensor 10 detects the display module, the baffle 6202 can clamp and fix the display module.

[0026] Protective pads 9 are installed on the storage base 6201, the stop bar 6202, and the guide rod 8. The protective pads 9 are extensible, allowing them to completely cover the storage base 6201, the stop bar 6202, and the guide rod 8 during operation. Figure 3 As shown, the protective pad 9 protects the storage base 6201, the stop bar 6202, and the guide rod 8 to prevent damage from hard contact collisions during the conveying of the display module on the conveying mechanism 12, thus ensuring the integrity of the display module during conveying. Distance sensors 15 are provided on both sides of the lower surface of the mounting base 21. The distance sensors 15 are electrically connected to an external controller. The distance sensors 15 operate using existing technology, such as... Figure 1 As shown, during the lamination process, the distance between the mounting base 21 and the display module is measured by the distance sensor 15 to prevent the mounting base 21 from colliding with the display module and causing damage to the display module, thereby protecting the display module.

[0027] Working principle: such as Figure 3 , Figure 6 As shown, the connection length between the storage base 6201 and the stop bar 6202 is adjusted according to the size of the display module so that after the stop bar 6202 blocks the display module, the center position of the display module corresponds to the center position of the mounting base 21. The storage base 6201 and the stop bar 6202 are locked and fixed by bolts 6203. like Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, the display module is conveyed by the conveying mechanism 12. During the conveying process of the display module, as... Figure 3 As shown, the display module on the conveying mechanism 12 is guided and conveyed by the guide rod 8, and the display module on the conveying mechanism 12 is blocked by the stop rod 6202; like Figure 3 As shown, when the photoelectric sensor 10 detects that the display module is blocked by the stop lever 6202, as Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, the third hydraulic cylinder 61 drives the storage base 6201 and the stop lever 6202 to move, thereby clamping and fixing the display module. Figure 3 As shown, the display module is buffered and protected by the protective pad 9; like Figure 2 , Figure 6 , Figure 7 As shown, the second motor 51 drives the lead screw 52 to rotate, and the lead screw 52 drives the support frame 31 and the first hydraulic cylinder 32 to move through the second slider 53. The first hydraulic cylinder 32 drives the mounting base 21 to move above the placement frame 42. like Figure 2 , Figures 5-7 As shown, the first hydraulic cylinder 32 drives the mounting base 21 to move via the fixed plate 33, causing the mounting base 21 to move above the protective film, as shown. Figure 1 , Figure 5 As shown, the external air extraction device adsorbs and fixes the protective film through the first connecting valve 28 and the second air hole 26. like Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, the second hydraulic cylinder 43 drives the cutter 44 to move, adjusting the cutter 44 to a suitable position. The lifting drive mechanism 41 drives the cutter 44 to move via the placement frame 42, and the cutter 44 cuts the protective film adsorbed on the mounting base 21; as shown. Figure 2 , Figure 6 , Figure 7 As shown, the second motor 51 drives the lead screw 52 to rotate in the opposite direction, so that the mounting base 21 moves above the display module; like Figure 2 , Figure 6 , Figure 7 As shown, the first hydraulic cylinder 32 drives the mounting base 21 to move via the fixed plate 33, causing the mounting base 21 and the protective film to move closer to the display module. During the movement of the mounting base 21, as... Figure 1 As shown, the distance between the mounting base 21 and the display module is measured by the distance sensor 15 to avoid collision between the mounting base 21 and the display module during film application; Figure 1 , Figure 5 As shown, the external air supply device blows air into the blower pipe 24 through the second connecting valve 29 and sprays it out through the first air hole 25. The sprayed air blows the protective film on the mounting base 21, so that the protective film adheres to the display module. like Figure 1 As shown, the first motor 27 drives the bidirectional screw 22 to rotate, the bidirectional screw 22 drives the first slider 23 to move, and the first slider 23 drives the blower pipe 24 to move, thereby adjusting the position of the blower pipe 24 so that the blower pipe 24 blows and flattens the protective film at different positions on the display module, thus completing the film coating of the display module.
