Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0027] Please also read Figures 1 to 6, the substrate coating mechanism provided by the utility model is now described. The substrate coating mechanism includes a platform 1, a film rolling roller 2, a film clamping assembly 3, an auxiliary assembly 4, a traction assembly 5 and a film pressing assembly 6. The platform 1 is provided with a support tray 7 for supporting the substrate and two first slide rails 11 respectively located on both sides of the support tray 7. The film rolling roller 2 is rotatably connected to the top of the platform 1 and located at the outer end of the first slide rail 11. The film clamping assembly 3 is arranged on the platform 1 and located on the discharge side of the film rolling roller 2. The auxiliary assembly 4 and the traction assembly 5 are sequentially slidably connected to the discharge side of the film clamping assembly 3, respectively used to clamp the front and rear side edges of the film material and drive the film material to move to the side of the support tray 7. The discharge side of the film clamping assembly 3 is slidably connected with a cutting knife 36 for cutting the film material.

[0028] Compared with the prior art, the substrate coating mechanism provided in the present embodiment is that the film material on the film winding roller 2 passes through the film clamping assembly 3 and is pulled forward to a fixed length by the traction assembly 5, and then the rear side edge is clamped by the auxiliary assembly 4, and the film material is cut with the help of the cutting knife 36. While the film clamping assembly 3 clamps the rear side film material, the cut film material is synchronously moved to the top of the substrate, and the film material is attached to the top of the substrate by the pressure roller assembly, which ensures the dimensional accuracy of the film material, enables precise positioning between the film material and the substrate, improves the dimensional accuracy of the coating, and ensures the coating quality of the substrate.

[0029] In this embodiment, for the sake of ease of description, the direction from the film rolling roller 2 to the traction component 5 is defined as the front, that is, the direction of movement of the film material, and the direction opposite to the front is defined as the rear. The traction component 5 is used to clamp the front side edge of the cut film material, and the auxiliary component 4 is used to clamp the rear side edge of the cut film material.

[0030] In one possible implementation, please also refer to Figures 1 to 6 The film clamping assembly 3 includes a mounting frame 37 arranged on the platform 1 and a first clamping nozzle 31 and a second clamping nozzle 32 respectively arranged on the mounting frame 37. The extension directions of the first clamping nozzle 31 and the second clamping nozzle 32 are respectively parallel to the axial direction of the film rolling roller 2, and the second clamping nozzle 32 is located on the side of the first clamping nozzle 31 away from the film rolling roller 2.

[0031] In this embodiment, the film clamping assembly 3 adopts a structure combining a first clamping nozzle 31 and a second clamping nozzle 32, which can be independently controlled to be opened or closed, and the film material can be pulled, cut and transferred through the cooperation of the two.

[0032] When in use, the film material passes through the first clamping nozzle 31 and the second clamping nozzle 32 from back to front in sequence and is reliably clamped by the first clamping nozzle 31 and the second clamping nozzle 32. When the traction component 5 moves backward to the position of the second clamping nozzle 32, the auxiliary component 4 and the second clamping nozzle 32 are both in an open state, and the first clamping nozzle 31 clamps the film material to ensure the stability of the front side edge of the film material and the position accuracy of the subsequent clamping of the traction component 5.

[0033] After the traction component 5 passes through the auxiliary component 4 and the second clamping nozzle 32 backward, it clamps the front side edge of the film material from the front side of the first clamping nozzle 31. After that, the traction component 5 pulls the film material forward to a fixed length, and the auxiliary component 4 and the first clamping nozzle 31 clamp the rear part of the film material respectively. The cutting knife 36 moves horizontally to cut the film material, and the cut film material is synchronously sent to the top of the substrate in the tray 7 by the traction component 5 and the auxiliary component 4. Finally, the film pressing component 6 moves downward horizontally to roll the top surface of the film material so that the film material is reliably attached to the top surface of the substrate.

[0034] In some embodiments, please refer to Figures 1 to 6 The first clamping nozzle 31 and the second clamping nozzle 32 respectively include an upper clamping bar 33, a lower clamping bar 34 and a lifting drive member 35. The upper clamping bar 33 and the lifting drive member 35 are respectively connected to the mounting frame 37. The lower clamping bar 34 is slidably connected to the mounting frame 37 along the up and down directions. The lower clamping bar 34 is located below the upper clamping bar 33 and is connected to the lifting drive member 35. The lower clamping bar 34 can move upward under the drive of the lifting drive member 35 to cooperate with the upper clamping bar 33 to clamp the film material.

[0035] In this embodiment, the plate surfaces of the upper clamping bar 33 and the lower clamping bar 34 are respectively arranged in the horizontal direction, and the extension direction of the two is arranged parallel to the axial direction of the film winding roller 2. When the first clamping nozzle 31 or the second clamping nozzle 32 is required to clamp the film material, the lifting drive member 35 can drive the lower clamping bar 34 to move up to abut against the upper clamping bar 33, so that the film material is stably located between the upper clamping bar 33 and the lower clamping bar 34, ensuring the stability of clamping, so that the position of the film material is effectively limited.

[0036] In one possible implementation, please also refer to Figures 1 to 6 The auxiliary component 4 includes a first slide 41, an auxiliary upper clamp 42, an auxiliary lifting roller 43 and a first lifting member 44. The first slide 41 is slidably connected to the first slide rail 11, the auxiliary upper clamp 42 is connected to the first slide 41, the auxiliary lifting roller 43 is slidably connected to the first slide 41 along the up and down directions and is located below the auxiliary upper clamp 42. The first lifting member 44 is connected to the first slide 41 and extends upward to be connected to the auxiliary lifting roller 43. The auxiliary lifting roller 43 can move upward under the drive of the first lifting member 44 to cooperate with the auxiliary upper clamp 42 to clamp the film material.

[0037] In this embodiment, the auxiliary upper clamping strip 42 is a strip-shaped plate-shaped member. When the film material is pulled by the pulling assembly 5, it is close to the bottom surface of the auxiliary upper clamping strip 42. When the film material needs to be clamped, the first lifting member 44 drives the auxiliary lifting roller 43 to move upward to cooperate with the auxiliary upper clamping strip 42 to clamp the film material, so as to facilitate the movement of the film material in cooperation with the pulling assembly 5. The auxiliary assembly 4 has a simple structure and precise action, which is convenient for the position accuracy of the clamping part.

[0038] In some embodiments, please refer to Figures 1 to 6The traction assembly 5 includes a second slide 51, an upper traction clamp 52, a traction lifting roller 53 and a second lifting member 54. The second slide 51 is slidably connected to the first slide rail 11, the upper traction clamp 52 is connected to the second slide 51, the traction lifting roller 53 is slidably connected to the second slide 51 along the up and down directions, and is located below the upper traction clamp 52. The second lifting member 54 is connected to the second slide 51 and extends upward to be connected to the traction lifting roller 53. It can be moved upward under the drive of the second lifting member 54 to cooperate with the auxiliary upper clamp 42 to clamp the film material.

[0039] In this embodiment, the structure of the traction component 5 is similar to that of the auxiliary component 4. The second lifting member 54 can be used to drive the auxiliary lifting roller 43 to move upward to cooperate with the traction upper clamping strip 52 to clamp the film material, and the front side edge of the film material can be effectively clamped and pulled.

[0040] Specifically, the first slide 41 and the second slide 51 are respectively connected to translation driving members for driving the translation thereof to meet the requirements of traction and movement of the film material.

[0041] In some embodiments, please refer to Figures 1 to 6 A first outrigger 55 and a second outrigger 56 are provided on one side of the second slide 51 adjacent to the auxiliary component 4, the traction upper clamp 52 is arranged on the first outrigger 55, the second outrigger 56 is slidably connected to the second slide 51, the traction lifting roller 53 is arranged on the second outrigger 56, the second lifting member 54 is connected to the second slide 51 and is located below the second outrigger 56, the second lifting member 54 extends upward to be connected to the second outrigger 56, and is used to drive the second outrigger 56 and the traction lifting roller 53 to move up and down.

[0042] In this embodiment, the first outrigger 55 and the second outrigger 56 are used to install the traction upper clamping strip 52 and the traction lifting roller 53. The first outrigger 55 and the second outrigger 56 extend toward the rear side of the second slide seat 51, so as to facilitate reaching into the auxiliary component 4 and the second clamping nozzle 32 to clamp the front side edge of the film material from the first clamping nozzle 31, thereby avoiding position interference between components and improving the rationality of the structural layout.

[0043] In some embodiments, please refer to Figures 1 to 6 The side of the second slide 51 is provided with a guide rail 57 extending in the up-down direction, and the second outrigger 56 is provided with a guide seat 58, which is slidably connected to the guide rail 57. Through the sliding cooperation between the guide rail 57 and the guide seat 58, the lifting action of the second outrigger 56 is effectively guided, the accuracy of the lifting action is ensured, and the traction assembly 5 is ensured to effectively clamp the film material, meeting the traction requirements.

[0044] Specifically, flexible layers may be provided on the peripheries of the auxiliary lifting roller 43 and the traction lifting roller 53 respectively to ensure the stability of the clamping force and achieve reliable clamping of the edge of the film material.

[0045] In one possible implementation, please also refer to Figures 1 to 6 The platform 1 is also provided with two second slide rails 12 which are respectively arranged perpendicular to the first slide rails 11. A rotating seat 13 is slidably connected to the second slide rails 12. The rotating seat 13 is supported under the support tray 7 and is used to drive the support tray 7 to rotate circumferentially or move horizontally along the second slide rails 12.

[0046] In this embodiment, orderly loading of the substrate on the support tray 7 can be achieved by setting the second slide rail 12. The rotating seat 13 has a rotating driving end that can drive the support tray 7 to rotate. When the support seat position angle deviates, the rotating driving end of the rotating seat 13 can drive the support tray 7 to rotate and adjust, thereby ensuring the accuracy of the initial position of the substrate.

[0047] In some embodiments, please refer to Figures 1 to 6 A first camera 81 for collecting first image information of the substrate in the tray 7 and a second camera 82 for collecting second image information of the film material are provided on the platform 1. The substrate coating mechanism also includes a controller electrically connected to the first camera 81 and the second camera 82 respectively. The controller is electrically connected to the rotating seat 13. The controller can be used to receive the first image information and the second image information, and send control information to the rotating seat 13.

[0048] In this embodiment, the first camera 81 is installed above the platform 1 through a frame, and can capture images of the substrate in the tray 7 to obtain first image information. The second camera 82 is set on the platform 1, located below the film material, and is used to collect second image information of the cut film material. The first image information and the second image information are sent to the controller for the preset program of the controller to determine whether the position is accurate. When the position is inaccurate, the controller can send a control instruction to the rotating seat 13, and the rotating seat 13 drives the tray 7 to rotate or drives the tray 7 to translate to achieve accurate positioning of the substrate.

[0049] On this basis, the controller can also send control instructions to the first slide 41 and the translation drive of the second slide to achieve effective adjustment of the film position, ensure effective alignment of the film and substrate, and further ensure the subsequent lamination accuracy.

[0050] In one possible implementation, please also refer to Figures 1 to 6The film pressing assembly 6 includes a third slide 61, a flexible pressure roller 62 and a third lifting member 63. The third slide 61 is slidably connected to the first slide rail 11. The flexible pressure roller 62 is slidably connected to the third slide 61 in the up-down direction. The third lifting member 63 is connected to the third slide 61 and extends downward to connect with the flexible pressure roller 62. The flexible pressure roller 62 moves downward to the surface of the film material under the drive of the third lifting member 63 and rolls the film material onto the substrate. The output end of the third lifting member 63 can move downward to press the flexible pressure roller 62 against the top surface of the film material, and then the third slide 61 drives the third lifting member 63 and the flexible pressure roller 62 to move, so that the film material is effectively attached to the top surface of the substrate, ensuring that the film is firmly and reliably coated.

[0051] Specifically, the flexible pressure roller 62 is connected to the bottom of the third lifting member 63 through the pressure roller seat 64. In order to improve the reliability of the lifting action, two guide columns 65 extending upward and penetrating the third slide seat 61 are arranged on the top of the pressure roller seat 64. The two guide columns 65 are respectively located on both sides of the third lifting member 63, which can effectively guide the lifting action of the third lifting member 63.

[0052] In one possible implementation, please also refer to Figures 1 to 6 A film guide roller 21 located below the film winding roller 2 is rotatably connected to the platform 1, and a guide brake frame 22 located below the film guide roller 21 is rotatably connected to the platform 1. The guide brake frame 22 is used to guide the film material into the film clamping assembly 3 or swing vertically to tension and brake the film material.

[0053] In this embodiment, the film guide roller 21 and the guide brake frame 22 on the platform 1 can both guide the film material. After the film material is released from the film winding roller 2, it extends around the peripheral wall of the film guide roller 21 to the roller body position on the front side of the guide brake frame 22. The film guide roller 21 and the guide brake frame 22 can provide a certain tension to the film material to ensure that the film material can move in an orderly manner under the traction action of the traction component 5.

[0054] Specifically, the film material passes under the front roller of the guide brake frame 22, and the film material is in a tensioned state when the roller can press down the film material under the action of its own weight. When the first clamping nozzle 31 clamps the film material for the traction assembly 5 to clamp the front edge of the film material, the roller body on the front side of the guide brake frame 22 swings downward to tension the film material, and the brake wheel at the rear of the guide brake frame 22 can abut against the outer peripheral wall of the roller shaft of the film guide roller 21 to achieve circumferential locking of the roller shaft, avoiding the film material from being loosened due to continued feeding, having a reliable braking effect, and ensuring the subsequent film material feeding accuracy, and then ensuring the subsequent film coating accuracy.

[0055] During use, the film material passes through the first clamping nozzle 31 and the second clamping nozzle 32 from back to front in sequence and is reliably clamped by the first clamping nozzle 31 and the second clamping nozzle 32. When the traction component 5 moves backward to the position of the second clamping nozzle 32, the auxiliary component 4 and the second clamping nozzle 32 are both in an open state, and the first clamping nozzle 31 clamps the film material to ensure the stability of the front side edge of the film material and the position accuracy of the subsequent clamping of the traction component 5.

[0056] After the traction component 5 passes through the auxiliary component 4 and the second clamping nozzle 32 backward, it clamps the front side edge of the film material from the front side of the first clamping nozzle 31. After that, the traction component 5 pulls the film material forward to a fixed length, and the auxiliary component 4 and the first clamping nozzle 31 clamp the rear part of the film material respectively. The cutting knife 36 moves horizontally to cut the film material, and the cut film material is synchronously sent to the top of the substrate in the tray 7 by the traction component 5 and the auxiliary component 4. Finally, the film pressing component 6 moves downward horizontally to roll the top surface of the film material so that the film material is reliably attached to the top surface of the substrate.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
