Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

Therefore, they should not be construed as limitations on this application.

[0089] It should be understood that the term "and / or" as used in this application specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0090] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0091] This application provides a coating device to solve the technical problem of low coating efficiency.

[0092] In the embodiments of this application, such as Figure 1 , Figure 2 , Figure 6 and Figure 10As shown, the laminating equipment includes a machine base 1, a frame 2, a first heating component 3, a conveying mechanism 4, a film pulling mechanism 5, a cutter 6, a first cavity 7, a first driving component 9, a second cavity 8, and a second heating component 10. The frame 2, the first heating component 3, the conveying mechanism 4, and the first cavity 7 are all disposed on the machine base 1. The film pulling mechanism 5 and the first driving component 9 are both disposed on the frame 2, with the film pulling mechanism 5 located above the conveying mechanism 4. The cutter 6 is disposed on the film pulling mechanism 5. The first cavity 7 and the first heating component 3 are spaced apart along a first direction. The second cavity 8 is disposed at the output end of the first driving component 9, and the second cavity 8 is located directly above the first cavity 7. The first driving component 9 is used to drive the second cavity 8 closer to the first cavity 7 so that the first cavity 7 and the second cavity 8 cover each other to form a sealed cavity. The second heating component 10 is disposed on the first cavity 7.

[0093] The conveying mechanism 4 is used to convey the jig assembly 200 from the heating position of the first heating component 3 to the lower part of the film stretching mechanism 5; the film stretching mechanism 5 is used to stretch the film onto the upper surface of the jig assembly 200; the cutter 6 is used to cut the film; the conveying mechanism 4 is also used to convey the jig assembly 200 to the first cavity 7; the jig assembly 200 is used to fix the product; the first direction is perpendicular to the up and down direction.

[0094] like Figure 1 As shown, the first direction is parallel to the Y-axis, the second direction is parallel to the X-axis, and the up-down direction is parallel to the Z-axis.

[0095] In this embodiment, the first heating component 3 heats the fixture assembly 200. After heating the fixture assembly 200 to a preset temperature, the conveying mechanism 4 removes the fixture assembly 200 from the heating position of the first heating component 3 and then conveys the fixture assembly 200 to the area below the film stretching mechanism 5. The film stretching mechanism 5 then stretches the film from one end of the fixture assembly 200 to the other end to cover the upper surface of the fixture assembly 200. After the film is covered on the upper surface of the fixture assembly 200, the cutter 6 cuts the film. After the cutter 6 cuts the film, the conveying mechanism 4 conveys the fixture assembly 200 to the first cavity 7. Then, the first driving component 9 drives the second... The cavity 8 descends to bring the second cavity 8 closer to the first cavity 7, so that the second cavity 8 and the first cavity 7 cover each other to form a sealed cavity. Then, the second heating component 10 heats the fixture assembly 200 in the sealed cavity to cover the product with a film on the upper surface of the fixture assembly 200. Since the fixture assembly 200 has been preheated by the first heating component 3 when the second heating component 10 heats the fixture assembly 200 in the sealed cavity, the fixture assembly 200 has a certain temperature when the conveying mechanism 4 conveys the fixture assembly 200 to the first cavity 7. This reduces the time it takes for the second heating component 10 to heat the fixture assembly 200 to the film coating temperature and improves the film coating efficiency of the product.

[0096] In one embodiment, such as Figure 1 , Figure 2 and Figure 8 As shown, the conveying mechanism 4 includes a rotating assembly 41 and a transport assembly 42. The rotating assembly 41 is disposed on the machine base 1, and the film stretching mechanism 5 is located above the rotating assembly 41. The rotating assembly 41 is disposed between the first cavity 7 and the first heating assembly 3. The transport assembly 42 is disposed on the machine base 1 and is used to transport the fixture assembly 200 from the heating position of the first heating assembly 3 to the rotating assembly 41. When the rotating assembly 41 rotates, it is used to transport the fixture assembly 200 to the first cavity 7.

[0097] After the first heating component 3 heats the fixture assembly 200 to a preset temperature, the transport component 42 removes the fixture assembly 200 from the heating position of the first heating component 3. Then, the transport component 42 conveys the fixture assembly 200 to the rotating component 41. Next, the film stretching mechanism 5 stretches the film from one end of the fixture assembly 200 to the other end, covering the upper surface of the fixture assembly 200, and then cuts the film using the cutter 6. Subsequently, the rotating component 41 rotates a certain angle to position the fixture assembly 200 directly above the first cavity 7, and then conveys the fixture assembly 200 to the first cavity 7. By conveying the fixture assembly 200 to the rotating component 41 via the transport component 42, the film stretching mechanism 5 can easily stretch the film.

[0098] In one embodiment, such as Figures 1 to 3 As shown, the conveying assembly 42 includes a first slide rail 421, a first driver, and a second driver 422. The first slide rail 421 is disposed on the machine base 1, and its extension direction is parallel to a first direction. The first driver is disposed on the machine base 1 or the first slide rail 421. The second driver 422 is slidably disposed on the first slide rail 421 and is connected to the output end of the first driver. The first driver is used to drive the second driver 422 to slide on the first slide rail 421, and the output end of the second driver 422 is used to drive the jig assembly 200 to rise and fall. The first heating assembly 3 is arranged side by side with the first slide rail 421 along a second direction. The second direction is perpendicular to both the first direction and the vertical direction.

[0099] The extension direction of the first slide rail 421 is parallel to the first direction. Therefore, the first driver drives the second driver 422 to slide on the first slide rail 421, allowing the second driver 422 to approach the rotating assembly 41. The output end of the second driver 422 moves in the vertical direction, thus the second driver 422 can drive the fixture assembly 200 to rise and fall. Since the first heating assembly 3 and the first slide rail 421 are arranged side by side along the second direction, the first driver can drive the second driver 422 to slide on the first slide rail 421 until it is parallel to the first heating assembly 3.

[0100] The second driver 422 can lower the fixture assembly 200 so that its bottom contacts the first heating assembly 3, thereby heating the fixture assembly 200. After the first heating assembly 3 heats the fixture assembly 200 to a preset temperature, the second driver 422 can lift the fixture assembly 200 so that the first driver drives the second driver 422 to transport the fixture assembly 200 to the rotating assembly 41.

[0101] Optionally, a positioning pin may be provided at the output end of the second driver 422 so that the jig assembly 200 can be quickly positioned at the output end of the second driver 422, thereby improving the conveying accuracy of the conveying assembly 42.

[0102] In one embodiment, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, the rotating assembly 41 includes a third driver 411, a rotating arm 412, a rotating blade 413, and a fourth driver 414. The third driver 411 is disposed on the machine base 1, located between the first cavity 7 and the first heating assembly 3. The rotating arm 412 is disposed at the output end of the third driver 411, and the third driver 411 drives the rotating arm 412 to rotate. Two rotating blades 413 are respectively disposed at both ends of the rotating arm 412, and the length direction of the rotating blades 413 is perpendicular to the length direction of the rotating arm 412. The fourth driver 414 is disposed on the rotating blades 413, and the extension direction of the output end of the fourth driver 414 is parallel to the length direction of the rotating arm 412. The film-stretching mechanism 5 is located above the space between the two rotating blades 413, and the film-stretching direction of the film-stretching mechanism 5 is parallel to the second direction.

[0103] As the transport assembly 42 conveys the jig assembly 200 above the space between the two rotating blades 413, such that the height of the jig assembly 200 is greater than the height of the output end of the fourth actuator 414, the output end of the fourth actuator 414 extends along the length of the rotating arm 412, protruding from the rotating blade 413. Then, the transport assembly 42 descends, so that the output end of the fourth actuator 414 lifts the jig assembly 200. Then, the film-pulling mechanism 5 pulls the film from one end of the jig assembly 200 to the other along the second direction, covering the upper surface of the jig assembly 200. Then, the third actuator 411 drives the rotating arm 412 to rotate, which in turn drives the rotating blade 413 to rotate, which in turn drives the jig assembly 200 to rotate. When the jig assembly 200 is rotated above the first cavity 7, the output end of the fourth actuator 414 retracts, placing the jig assembly 200 inside the first cavity 7.

[0104] The structure consisting of the rotating arm 412 and the rotating blade 413 has a shape similar to the "I" shape, so as to support the jig assembly 200. Understandably, a fourth driver 414 can be provided on each of the two rotating blades 413 to support both ends of the jig assembly 200 through the output end of the fourth driver 414, thereby improving the stability of supporting the jig assembly 200.

[0105] In one embodiment, such as Figure 2 and Figure 5 As shown, the rotating assembly 41 also includes a fifth driver 415, which is disposed on the rotating blade 413. The extension and retraction direction of the output end of the fifth driver 415 is parallel to the length direction of the rotating arm 412, and the output end of the fifth driver 415 is located below the output end of the fourth driver 414.

[0106] The output end of the fifth actuator 415 can extend along the length of the rotating arm 412 so that the output end of the fifth actuator 415 protrudes from the rotating wing 413, so that the output end of the fifth actuator 415 can support the jig assembly 200. Since the height of the output end of the fifth actuator 415 is lower than the height of the output end of the fourth actuator 414, the fifth actuator 415 can also support the jig assembly 200.

[0107] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, the fixture assembly 200 includes a fixture plate 2002, a fixture body 2003, and a covering plate 2001; the covering plate 2001 is disposed above the fixture plate 2002, and a positioning hole 20011 is provided on the covering plate 2001; the fixture body 2003 is disposed on the fixture plate 2002, and the fixture body 2003 protrudes from the positioning hole 20011. The output end of the fourth driver 414 is used to support the covering plate 2001, and the output end of the fifth driver 415 is used to support the fixture plate 2002.

[0108] When the fourth driver 414 lifts the coating plate 2001 at its output end, the conveying assembly 42 can transport the fixture plate 2002 to the heating position of the first heating assembly 3 for heating, so that the temperature of the fixture body 2003 set on the fixture plate 2002 is maintained at a preset temperature. This further reduces the heat loss of the fixture body 2003 and improves the coating efficiency of the product.

[0109] In one embodiment, such as Figure 1 , Figure 2 and Figure 5As shown, a fourth driver 414 and a fifth driver 415 are provided at both ends of the rotating blade 413 to form two workstations at both ends of the rotating blade 413. When the film is pulled at the workstation close to the first heating component 3, the loading and unloading fixture assembly 200 is used at the workstation away from the first heating component 3 to perform alternating film pulling at the two workstations, thereby improving the film coating efficiency.

[0110] In one embodiment, such as Figure 1 , Figure 2 and Figure 5 As shown, the conveying mechanism 4 also includes a sixth drive 43, which is disposed on the machine base 1. The output end of the sixth drive 43 is used to lift the jig assembly 200 on the conveying assembly 42 above the output end of the fourth drive 414. When the conveying assembly 42 conveys the jig assembly 200 to below the space between the two rotating blades 413, the output end of the sixth drive 43 is lifted to raise the height of the jig assembly 200 above the space between the two rotating blades 413, so as to facilitate the fourth drive 414 to extend and lift the jig assembly 200.

[0111] Specifically, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the output of the sixth driver 43 is used to lift the film-coating plate 2001 to raise its height, so that the output of the fourth driver 414 can extend to support the film-coating plate 2001. After the cutter 6 cuts the film, the transport assembly 42, i.e., the second driver 422, is used to lift the fixture plate 2002, so that the output of the fifth driver 415 can extend to support the fixture plate 2002.

[0112] In one embodiment, such as Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, the conveying mechanism 4 also includes a seventh driver 44, which is disposed on the machine base 1. The output end of the seventh driver 44 is used to receive the jig assembly 200 on the rotating assembly 41, and the output end of the seventh driver 44 moves in the vertical direction. The seventh driver 44 is disposed close to the first cavity 7 relative to the sixth driver 43. After the rotating assembly 41 drives the jig assembly 200 to rotate, that is, after the third driver 411 indirectly drives the jig assembly 200 to rotate through the rotating arm 412, the output end of the seventh driver 44 is lifted to support the jig assembly 200 lowered by the rotating assembly 41 and to convey the jig assembly 200 to the first cavity 7.

[0113] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 9 and Figure 10 As shown, the second heating assembly 10 includes a thirteenth driver 101 and a second heating plate 102, with the second heating plate 102 disposed at the output end of the thirteenth driver 101. After the rotating assembly 41 rotates 180 degrees, the output end of the seventh driver 44 rises, and the output end of the fourth driver 414 retracts, to lift the coating plate 2001 through the output end of the seventh driver 44. Simultaneously, the thirteenth driver 101 drives the second heating plate 102 to rise, and the output end of the fifth driver 415 retracts, to lift the fixture plate 2002 through the second heating plate 102. Then, the thirteenth driver 101 drives the second heating plate 102 to descend, to lift the fixture plate 2002 into the first cavity 7 through the second heating plate 102. Subsequently, the output end of the seventh driver 44 also descends, to place the coating plate 2001 at the opening of the first cavity 7, thereby realizing the conveying of the fixture assembly 200.

[0114] Optionally, such as Figure 1 , Figure 2 , Figure 5 , Figure 9 and Figure 10 As shown, after the rotating assembly 41 rotates 180 degrees, the output end of the seventh driver 44 rises, and the output end of the fifth driver 415 retracts, so as to lift the jig plate 2002 through the output end of the seventh driver 44. Then, the thirteenth driver 101 drives the second heating plate 102 to rise, so as to lift the jig plate 2002 through the second heating plate 102; then the output end of the seventh driver 44 descends, and the thirteenth driver 101 drives the second heating plate 102 to descend subsequently, so as to lift the jig plate 2002 into the first cavity 7 through the second heating plate 102. Then the output end of the seventh driver 44 rises again, and the output end of the fourth driver 414 retracts subsequently, so as to lift the coating plate 2001 through the output end of the seventh driver 44; then the output end of the seventh driver 44 descends, so as to place the coating plate 2001 at the opening of the first cavity 7, thereby realizing the conveying of the jig assembly 200.

[0115] In one embodiment, such as Figure 1 , Figure 2 and Figure 6 As shown, the film stretching mechanism 5 includes a second slide rail 51, an eighth driver, a sliding bracket 52, and a gripper 53. The second slide rail 51 is mounted on the frame 2, located above the conveying mechanism 4, and its extension direction is parallel to the second direction. The eighth driver is mounted on either the frame 2 or the second slide rail 51. The sliding bracket 52 is slidably mounted on the second slide rail 51 and is connected to the output end of the eighth driver. The eighth driver drives the sliding bracket 52 to slide on the second slide rail 51. A cutter 6 is mounted on the sliding bracket 52. The gripper 53 is mounted on the sliding bracket 52 and is used to clamp the film.

[0116] The sliding bracket 52 is slidably mounted on the second slide rail 51, and the gripper 53 is mounted on the sliding bracket 52. After the gripper 53 clamps the film, the eighth driver drives the sliding bracket 52 to slide on the second slide rail 51 to pull the film from one end of the fixture assembly 200 to the other end along the second direction. Then, the film is cut by the cutter 6 mounted on the sliding bracket 52 to cover the fixture assembly 200.

[0117] In one embodiment, such as Figure 7 As shown, the gripper 53 includes a fourteenth actuator 531, a clamping block 532, and a pressure block 533. Both the fourteenth actuator 531 and the clamping block 532 are mounted on the sliding bracket 52. The pressure block 533 is located at the output end of the fourteenth actuator 531. The fourteenth actuator 531 drives the pressure block 533 to move closer to or further away from the clamping block 532 in the vertical direction to clamp or release the film. When the fourteenth actuator 531 drives the pressure block 533 to press the film onto the clamping block 532, the eighth actuator can drive the sliding bracket 52 to slide, thereby achieving film stretching.

[0118] In one embodiment, such as Figure 6 As shown, there are two grippers 53, which are spaced apart along the first direction to clamp the two sides of the film respectively.

[0119] In one embodiment, such as Figure 6 and Figure 7 As shown, the film stretching mechanism 5 also includes an adjusting block 54, which is disposed on the sliding bracket 52. A gripper 53 is disposed on the adjusting block 54, and the position of the gripper 53 relative to the adjusting block 54 can be adjusted along a first direction. By adjusting the position of the gripper 53 relative to the adjusting block 54 along the first direction, the gripper 53 can clamp films of different widths, thereby improving the compatibility of the film stretching mechanism 5.

[0120] In one embodiment, such as Figure 6 and Figure 7 As shown, the film stretching mechanism 5 also includes a positioning element. The adjusting block 54 is provided with a sliding groove 541, the gripper 53 slides in the sliding groove 541, and the positioning element passes through the gripper 53 to position the gripper 53 within the sliding groove 541. The positioning element can be a screw.

[0121] In one embodiment, such as Figure 1 , Figure 6 and Figure 7As shown, the laminating equipment also includes a rolling shaft 300, which is mounted on the sliding support 52. A protective film is placed below the film, and the rolling shaft 300 is used to tension the film and the protective film. After the film and the protective film are wound around the rolling shaft 300, the protective film is retracted, and the film is clamped by the grippers 53, so that the film and the protective film are separated after being tensioned by the rolling shaft 300, thereby reducing dust contamination on the film. This avoids the problem of dust contamination on the film caused by the film and protective film separating at the beginning of the film stretching position. The rolling shaft 300 and the grippers 53 are arranged sequentially along the film stretching direction of the film stretching mechanism 5.

[0122] Specifically, after the film and protective film are wound around the rolling shaft 300, the gripper 53 clamps the film. The end of the protective film separates from the end of the film and is wound around the take-up roller 903. Since the rolling shaft 300 and the gripper 53 are arranged sequentially along the film pulling direction of the film pulling mechanism 5, when the eighth driver drives the sliding bracket 52 to slide in the second direction so that the gripper 53 pulls the film from one end of the fixture assembly 200 to the other end, the protective film under the film is also pulled to the other end of the fixture assembly 200 under the action of the rolling shaft 300. Then the gripper 53 releases the film, and the eighth driver drives the sliding bracket 52 to slide in the opposite direction. That is, during the process of the sliding bracket 52 returning to the film pulling starting position, the take-up roller 903 simultaneously winds up the film so that the film separates from the protective film under the film near the rolling shaft 300 position, thereby avoiding the problem of the film being contaminated with more dust at the film pulling starting position. Once the film is pulled into place, it will adhere to the film-coating plate 2001, or the film will be pressed onto the film-coating plate 2001 by the pressure plate 50, so that the take-up roller 903 can recycle the protective film, so that the film and the protective film can be separated during the retraction of the sliding bracket 52.

[0123] In one embodiment, such as Figure 6 and Figure 7 As shown, the laminating device also includes a ninth driver 20 and a tenth driver 30. The ninth driver 20 is disposed on the sliding bracket 52. The tenth driver 30 is disposed at the output end of the ninth driver 20, and the ninth driver 20 is used to drive the tenth driver 30 to move up and down; the cutter 6 is disposed at the output end of the tenth driver 30, and the tenth driver 30 is used to drive the cutter 6 to move along a first direction.

[0124] After the eighth driver drives the sliding bracket 52 to slide, so as to move the cutter 6 along the second direction to the position to be cut on the film, the ninth driver 20 drives the tenth driver 30 to descend, so that the height of the cutter 6 set at the output end of the tenth driver 30 is lower than the height of the gripper 53. Then the tenth driver 30 drives the cutter 6 to move along the first direction, so as to cut the film by the cutter 6.

[0125] In one embodiment, such as Figure 1 and Figure 2 As shown, the laminating equipment also includes an eleventh driver 40 and a pressure plate 50; the eleventh driver 40 is mounted on the frame 2; the pressure plate 50 is located at the output end of the eleventh driver 40, and the eleventh driver 40 drives the pressure plate 50 to move up and down. The pressure plate 50 is located above the conveying mechanism 4. After the film pulling mechanism 5 pulls the film from one end of the fixture assembly 200 to the other end, the eleventh driver 40 drives the pressure plate 50 to descend, so as to press the film firmly onto the fixture assembly 200 through the pressure plate 50, and then the film is cut by the cutter 6. This avoids displacement of the film relative to the fixture assembly 200 when the cutter 6 cuts the film, which would affect the cutting accuracy of the cutter 6.

[0126] In one embodiment, multiple eleventh actuators 40 and pressure plates 50 can be provided to drive the pressure plates 50 to press the film at different positions through the eleventh actuator 40, thereby further improving the cutting accuracy of the cutter 6.

[0127] In one embodiment, such as Figures 1 to 3 As shown, the first heating assembly 3 includes a twelfth driver 31 and a first heating plate 32. The twelfth driver 31 is mounted on the machine base 1. The first heating plate 32 is located at the output end of the twelfth driver 31. The twelfth driver 31 drives the first heating plate 32 to move up and down. The twelfth driver 31 can drive the first heating plate 32 to rise so that the first heating plate 32 contacts the bottom of the fixture assembly 200 conveyed by the conveying mechanism 4, thereby heating the fixture assembly 200 through the first heating plate 32. After the first heating plate 32 heats the fixture assembly 200 to a preset temperature, the twelfth driver 31 then drives the first heating plate 32 to fall, so as to facilitate the conveying mechanism 4 to convey the fixture assembly 200.

[0128] Specifically, while the second driver 422 of the conveying component 42 drives the fixture component 200 to descend, the twelfth driver 31 drives the first heating plate 32 to rise, so that the first heating plate 32 can quickly contact the fixture component 200, thereby improving the heating efficiency of the first heating plate 32 on the fixture component 200.

[0129] In one embodiment, such as Figure 10 As shown, the coating equipment also includes a third heating component 60, which is disposed in the second cavity 8. By heating the fixture assembly 200 through the third heating component 60 disposed in the second cavity 8, the heating efficiency and uniformity of the fixture assembly 200 can be improved, thereby improving the consistency of the coating.

[0130] Specifically, such as Figure 3 and Figure 10As shown, the third heating component 60 is used to heat the film on the film-coated plate 2001, and the second heating component 10 is used to heat the fixture plate 2002.

[0131] In one embodiment, such as Figure 2 and Figure 3 As shown, the fixture assembly 200 includes a fixture plate 2002, a fixture body 2003, and a covering plate 2001. The fixture body 2003 is disposed on the fixture plate 2002 and is used to place the product. The covering plate 2001 is provided with a positioning hole 20011 and is disposed above the fixture plate 2002. The fixture body 2003 protrudes from the positioning hole 20011.

[0132] Because the fixture body 2003 protrudes from the positioning hole 20011, the side wall of the fixture body 2003 abuts against the wall of the positioning hole 20011, thereby limiting the coating plate 2001 by the side wall of the fixture body 2003. Since the coating plate 2001 is positioned above the fixture plate 2002, the film on the coating plate 2001 can be heated by the third heating component 60, and the fixture plate 2002 can be heated by the second heating component 10, so that the film is coated onto the product on the fixture body 2003. This improves the uniformity of heating and enhances the consistency of the coating.

[0133] In one embodiment, mounting holes can be provided on the fixture plate 2002 to house the fixture body 2003, thereby facilitating direct heating of the fixture body 2003 from below and improving the heating efficiency of the fixture body 2003.

[0134] In one embodiment, such as Figure 3 as well as Figures 8 to 10 As shown, the second heating assembly 10 includes a thirteenth driver 101 and a second heating plate 102. The thirteenth driver 101 is disposed in the first cavity 7 or the machine base 1. The second heating plate 102 is disposed at the output end of the thirteenth driver 101. The thirteenth driver 101 is used to drive the second heating plate 102 to rise and fall within the first cavity 7. After heating the film on the fixture plate 2002 and the coating plate 2001 to the coating temperature, the thirteenth driver 101 drives the second heating plate 102 to rise, so that the fixture body 2003 protrudes from the positioning hole 20011 on the coating plate 2001, so that the film on the coating plate 2001 is stretched and adhered to the product, so that the film is coated on the product.

[0135] Specifically, the thirteenth driver 101 drives the second heating plate 102 to rise, which can lift the fixture plate 2002 when the conveying mechanism 4 releases it, so that the fixture plate 2002 can be lifted into the first cavity 7 by the thirteenth driver 101.

[0136] In one embodiment, the length of the coating plate 2001 is greater than the length of the fixture plate 2002; a placement position is provided at the opening of the first cavity 7 for placing the coating plate 2001; the length of the fixture plate 2002 is less than the opening length of the first cavity 7. Since the length of the coating plate 2001 is greater than the length of the fixture plate 2002, the coating plate 2001 can be directly supported from below the fixture plate 2002. After the thirteenth actuator 101 drives the second heating plate 102 to lift the fixture plate 2002 into the first cavity 7, the conveying mechanism 4 places the coating plate 2001 at the placement position at the opening of the first cavity 7.

[0137] Since the placement position is located at the opening of the first cavity 7, and the length of the fixture plate 2002 is less than the opening length of the first cavity 7, the second heating plate 102 can lift the fixture plate 2002 downward through the opening of the first cavity 7 to lift the fixture plate 2002 into the first cavity 7; while the coating plate 2001 can be placed at the placement position to heat the fixture plate 2002 and the coating plate 2001 separately, so as to prevent the film on the coating plate 2001 from being supported by the fixture body 2003.

[0138] In one embodiment, a first vacuum port is provided on the first cavity 7, and a second vacuum port and an air inlet are provided on the second cavity 8. The first vacuum port allows for vacuuming of the first cavity 7, and the second vacuum port allows for vacuuming of the second cavity 8. After vacuuming the first cavity 7 and the second cavity 8 respectively, the fixture assembly 200 and the film are heated. After heating the fixture assembly 200 and the film to the coating temperature, air is introduced into the second cavity 8 through the air inlet. At this time, the pressure inside the second cavity 8 is greater than the pressure inside the first cavity 7, thereby using the pressure difference to coat the product with the film, reducing the generation of bubbles and wrinkles.

[0139] In one embodiment, such as Figure 3 and Figure 9 As shown, the coating equipment also includes at least two temperature sensors 70, with at least one temperature sensor 70 disposed in the first cavity 7 and at least one temperature sensor 70 disposed in the second cavity 8. The temperature sensors 70 detect whether the temperature of the fixture assembly 200 has been heated to the coating temperature, thereby improving the coating quality. Specifically, the temperature sensors 70 are used to detect the temperature of the fixture plate 2002 and the film.

[0140] In one embodiment, such as Figure 3 and Figure 9As shown, the coating equipment also includes at least two pressure sensors 80, with at least one pressure sensor 80 disposed in the first cavity 7 and at least one pressure sensor 80 disposed in the second cavity 8. By measuring the pressure in the first cavity 7 and the second cavity 8 using the pressure sensors 80, it is easy to determine whether the vacuum has been properly applied, and it is also used to determine whether the pressure difference between the second cavity 8 and the first cavity 7 meets the pressure difference required for coating, thereby improving the coating quality.

[0141] In one embodiment, such as Figure 1 As shown, the laminating equipment also includes an unwinding mechanism 90, which is used to unwind the film so that the film pulling mechanism 5 can clamp the film unwound by the unwinding mechanism 90 and then pull the film along the second direction.

[0142] In one embodiment, the film material on the unwinding mechanism 90 has multiple layers, with the thin film located in the interlayer of the protective film to protect the thin film through the protective film.

[0143] In one embodiment, such as Figure 1 As shown, the unwinding mechanism 90 includes a mounting base 901, an unwinding roller 902, a take-up roller 903, and a tensioning shaft 904. The unwinding roller 902, take-up roller 903, and tensioning shaft 904 are all mounted on the mounting base 901. The unwinding roller 902 is used to hold the wound film material for unwinding; the take-up roller 903 is used to wind the protective film; and the tensioning shaft 904 is used to tension the film and the protective film.

[0144] In one embodiment, the upper protective film can be a light film, the thin film can be an OCA film, and the lower protective film can be a heavy film. The heavy film is wound around the take-up roller 903 after passing over the rolling shaft 300.

[0145] In one embodiment, such as Figure 1 As shown, the coating equipment also includes an ion fan 100 for removing static electricity and dust.

[0146] In one embodiment, such as Figure 1 and Figure 4 As shown, multiple ion fans 100 are provided, with some ion fans 100 mounted on the mounting base 901 and others mounted on the frame 2. The air outlets of the ion fans 100 mounted on the frame 2 face the conveying mechanism 4. Specifically, the air outlets of the ion fans 100 mounted on the frame 2 face the space between the rotating blades 413.

[0147] like Figures 1 to 10 As shown, the coating process of the preferred embodiment of this application will now be described as follows:

[0148] The second actuator 422 lowers the fixture assembly 200, while the twelfth actuator 31 raises the first heating plate 32 so that it contacts the lower surface of the fixture plate 2002, thereby heating the fixture body 2003 on the fixture plate 2002. After the fixture plate 2002 is heated to a preset temperature, the second actuator 422 raises the fixture assembly 200, while the twelfth actuator 31 lowers the first heating plate 32.

[0149] The first actuator drives the second actuator 422 to slide on the first slide rail 421. When the jig assembly 200 is conveyed to the space below the two rotating blades 413, the output end of the sixth actuator 43 lifts the covering plate 2001 to raise it above the output end of the fourth actuator 414. Then the output end of the fourth actuator 414 extends to hold the covering plate 2001. Then the output end of the sixth actuator 43 descends, and the first actuator drives the second actuator 422 to slide towards the first heating plate 32 to continue heating the jig plate 2002 through the first heating plate 32, thereby keeping the jig body 2003 on the jig plate 2002 warm.

[0150] Simultaneously, the eighth actuator drives the gripper 53 to move to the end of the film via the sliding bracket 52, and the fourteenth actuator 531 drives the pressure block 533 to press the film against the clamping block 532. Then, the eighth actuator again drives the gripper 53 to move along the second direction via the sliding bracket 52 to move away from the unwinding roller 902, that is, to pull the film from one end of the coating plate 2001 to the other end of the coating plate 2001, thereby realizing film pulling.

[0151] After the eleventh driver 40 drives the pressure plate 50 to press the end of the film onto the laminating plate 2001, the eighth driver drives the sliding bracket 52 to move toward the unwinding roller 902, so that the sliding bracket 52 returns to the film-pulling starting position. During the process of the sliding bracket 52 returning to the film-pulling starting position, the take-up roller 903 begins to retract the heavy film, so that the film (i.e., the OCA film) separates from the heavy film near the rolling shaft 300. Simultaneously, the other pressure plates 50 also press the film at corresponding positions.

[0152] After the sliding bracket 52 returns to the film-pulling starting position, it also moves the cutter 6 to the film-cutting position. The ninth actuator 20 drives the tenth actuator 30 to descend. After the cutter 6 presses against the film, the tenth actuator 30 drives the cutter 6 to move along the first direction to cut the film. Then the cutter 6 returns to its original position.

[0153] At the same time, the first driver drives the second driver 422 to transport the jig plate 2002 below the coating plate 2001. The second driver 422 lifts the jig plate 2002 so that the height of the jig plate 2002 is higher than the height of the output end of the fifth driver 415, and then the output end of the fifth driver 415 extends to hold the jig plate 2002.

[0154] The third actuator 411 drives the rotating arm 412 to rotate 180 degrees. The output end of the seventh actuator 44 rises, and after the output end of the fourth actuator 414 retracts, it supports the coating plate 2001. The thirteenth actuator 101 drives the second heating plate 102 to rise, and after the output end of the fifth actuator 415 retracts, it supports the fixture plate 2002. Then, the thirteenth actuator 101 drives the second heating plate 102 to descend, lifting the fixture plate 2002 into the first cavity 7. Then, the seventh actuator 44 drives the coating plate 2001 to descend, placing the coating plate 2001 in the placement position at the opening of the first cavity 7.

[0155] The first drive assembly 9 drives the second cavity 8 to descend, so that the second cavity 8 and the first cavity 7 close together to form a sealed cavity. Vacuum is drawn into the first cavity 7 and the second cavity 8 respectively, and then the fixture plate 2002 is heated by the second heating plate 102, and the film on the coating plate 2001 is heated by the third heating assembly 60.

[0156] After the jig plate 2002 and the film have reached the required temperature, the thirteenth actuator 101 drives the second heating plate 102 to rise, so that the jig plate 2002 fits against the bottom of the film-coating plate 2001, and the jig body 2003 protrudes from the positioning hole 20011. Then, air is injected into the second cavity 8 through the air inlet to cover the product with the film through the pressure difference.

[0157] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
