Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please refer to Figure 1 , Figure 2 and Figure 7A fully automatic release paper cleaning and laminating device is disclosed, which first cleans the base paper and then laminates the coating and base paper to form a complete release paper. It includes a support box 1 and a front and back cleaning mechanism 2, a transfer mechanism 3, and a laminating mechanism 130 arranged sequentially along the length of the support box 1. The support box 1 houses the device's control electrical components. The front and back cleaning mechanism 2 cleans both sides of a single sheet of base paper at a time. The transfer mechanism 3 transfers the cleaned base paper to the laminating mechanism 130 or the defective product area 150. Structure 130 includes at least one film-applying unit 140. Each film-applying unit 140 includes a film-coating and paper-storage assembly 141, a film-applying and adsorption assembly 142, and two flattening assemblies 143. The flattening assembly 143 includes a cutting structure 1433 disposed on the side for cutting after flattening and adsorption of the film. The two flattening assemblies 143 can move along the same U-shaped trajectory to alternately apply a pulling force to the end of the film. The film-applying and adsorption assembly 142 is used to adsorb the backing paper onto the flattening assembly 143 closer to the end of the film, thereby achieving adhesion with the film.

[0043] The entire system employs a structure with two interconnected tracks to sequentially adsorb the lower and upper surfaces of the release paper. This allows for rapid cleaning of both surfaces via a blowing assembly. Simultaneously, two flattening components 143, moving along the same trajectory, alternately cut the release paper and horizontally pull the coating during adsorption. Furthermore, a film-adsorption component 142 adheres the base paper and the cut coating, and rapidly adsorbs and transfers the adhered release paper. The ingenious design of the overall equipment enables fully automated cleaning of used base paper and automatic adhesion of the coating and base paper. The smooth workflow between each process significantly improves the efficiency of batch cleaning, adhesion, and cutting of release paper.

[0044] Please refer to Figure 2The front and back cleaning mechanism 2 includes a first support platform 10, a release paper fixing tray 20, and an upper moving track 30 and a lower moving track 40 arranged horizontally along the length of the support box 1. The lower moving track 40 can drive the release paper fixing tray 20 to reciprocate along the feeding direction. The lower moving track 40 and the upper moving track 30 are spliced ​​end to end and partially overlapped so that the moving adsorption component 50 can quickly grab a single release paper on the release paper fixing tray 20, which is also located at an extreme position, to improve the overall cleaning efficiency. A moving adsorption component 50 is movably arranged on the upper moving track 30 to realize the back-and-forth transfer of release paper between the upper moving track 30 and the lower moving track 40. A first blowing component 60 is mounted above the lower moving track 40 with the air outlet facing downward. A second blowing component 70 is arranged below the upper moving track 30 with the air outlet facing upward.

[0045] Please refer to Figure 3 and Figure 4 The mobile adsorption assembly 50 includes a driving component 51 and an adsorption component 52. The driving component 51 uses a conventional driving method, such as an electric moving module or a lead screw 14331 group, to control its lateral movement. The adsorption component 52 includes a connecting plate 521, a first pushing cylinder 522, an adsorption plate 523, and several guide columns 524. The connecting plate 521 is fixed to the driving component 51 to drive the adsorption component 52. The first pushing cylinder 522 is fixed to the connecting plate 521, and its push rod is fixedly connected to the adsorption plate 523 located directly below the connecting plate 521 to drive the adsorption plate 523 to rise and fall. The adsorption plate 523 has several evenly arranged ventilation holes and is connected to an external air source through an air pipe. There are four guide columns 524, which are fixedly arranged between the connecting plate 521 and the adsorption plate 523 to guide the adsorption plate 523 when it rises and falls when the first pushing cylinder 522 is working.

[0046] The adsorption component 52 further includes several pressing mechanisms 53. Each pressing mechanism 53 includes a second pushing cylinder 531, a connecting block 532, and a pressing wheel 533. There are four pressing mechanisms 53, which are located at the four corners of the adsorption plate 523. The pushing direction of the second pushing cylinder 531 is horizontal and outward. The pressing wheel 533 is connected to the connecting plate 521 so that its position is below the adsorption plate 523. The connecting plate 521 includes a first connecting member 5321 and a second connecting member 5322. A guide rail is provided on the first connecting member 5321 to cooperate with the second pushing cylinder 531 to realize the reciprocating movement of the second connecting member 5322 on the guide rail. The pressing wheel 533 is fixed below the second connecting member 5322 and is further pressed by the second pushing cylinder 531 after the release paper is adsorbed, so as to prevent it from falling downward.

[0047] Please refer to Figure 5 The release paper fixing tray 20 is fixedly connected to an electric moving module via a connector. The release paper fixing tray 20 is provided with a plurality of adsorption through holes evenly distributed on it for adsorbing the bottom paper of a single release paper. A limit switch is further provided below the release paper fixing tray 20 to control the release paper fixing tray 20 to stop moving at the extreme position.

[0048] Please refer to Figure 2 The lower moving track 40 and the upper moving track 30 are arranged sequentially along the length of the support box 1, and the end of the lower moving track 40 overlaps with the head of the upper moving track 30 in the vertical projection direction.

[0049] The structure in which the lower moving track 40 is positioned in front of the upper moving track 30 can effectively grab the release paper onto the release paper fixing tray 20 through the gripper outside the mechanism. Then, the release paper on the tray can be smoothly removed by the moving adsorption component 50 on the upper moving track 30 in conjunction with the overlapping setting position. The whole process is designed to be smooth and can maximize the turnover efficiency of the release paper.

[0050] Please refer to Figure 5 The fully automatic release paper automatic cleaning and film application equipment is further provided with a first light source assembly 80 and a first camera group 90. The first light source assembly 80 is mounted above the lower moving track 40 and is located behind the first blowing assembly 60 along the length direction of the support box 1. The first camera group 90 is located directly above the first light source assembly 80.

[0051] Because the cleanliness requirements for the release paper are very high, the surface of the release paper needs to be illuminated by the first light source assembly 80 before it can be accurately and clearly photographed by the first shooting unit.

[0052] Furthermore, the first light source assembly 80 is an arched linear light source to generate a strong light source at a linear position. The first light source assembly 80 illuminates the light source downwards to illuminate the release paper passing through the lower moving track 40. The housing of the first light source assembly 80 is provided with a strip-shaped hole for allowing the first shooting camera group 90 to take pictures. The first shooting camera group 90 also acquires images of each linear position through continuous and rapid shooting and finally stitches them together to form the final complete picture of the release paper.

[0053] Similarly, please refer to Figure 2 and Figure 3 The fully automatic release paper automatic cleaning and film application equipment is further provided with a second light source assembly 100 and a second camera group 110. The second light source assembly 100 is located below the upper moving track 30 and is located behind the second blowing assembly 70 along the length direction of the support box 1. The second camera group 110 is located directly below the second light source assembly 100.

[0054] The second light source assembly 100 is an arched line light source. The second light source assembly 100 illuminates the light source upward to illuminate the release paper passing through the upper moving track 30. The housing of the second light source assembly 100 has a strip hole for making way for the second shooting camera group 110 to take pictures.

[0055] Please refer to Figure 3 and Figure 5 The first blowing assembly 60 and the second blowing assembly 70 have the same structure. The first blowing assembly 60 includes a non-contact cyclone cleaning system 61 and a support frame 62. The support frame 62 has a limiting hole for the air duct of the non-contact cyclone cleaning system 61 to pass through. This structure can effectively achieve stable fixation of the cleaning system and ensure that the fixation will not be unstable due to vibration during the blowing dust removal process.

[0056] Please refer to Figure 1 and 6 The automatic release paper cleaning and film application equipment further includes at least one bottom paper feeding station 4 located at the head of the equipment and on the side of the release paper fixing tray 20. A movable feeding mechanism 5 is provided above the bottom paper feeding station 4 to transfer the bottom paper of the bottom paper feeding station 4 to the release paper fixing tray 20. Preferably, there are two bottom paper feeding stations 4, located on the left and right sides of the release paper fixing tray 20 respectively.

[0057] The first support platform 10 is further provided with several fixed beams 120 to cooperate in fixing the mobile feeding mechanism 5, the upper moving track 30, the support frame 62, the first shooting camera group 90 and the first blowing assembly 60, etc., so as to achieve stable fixation of the overall mechanism and ensure smooth overall workflow.

[0058] Please refer to Figure 7 and Figure 8 The film applicator further includes a second support platform 144 and three film applicator moving modules 145 disposed on the second support platform 144. Each film applicator moving module 145 includes an electric slide rail for horizontal reciprocating motion and an electric cylinder for vertical reciprocating motion, to respectively realize the translation and lifting of the film applicator adsorption component 142 and the two flattening components 143. The film applicator moving module 145 used to fix the film applicator adsorption component 142 is fixed to a suspension bracket located on the second support platform 144, allowing the film applicator adsorption component 142 to move above the flattening components 143. The film applicator moving module 145 further includes multiple adsorption suction cups for adsorbing the base paper. The other two film applicator moving modules 145 used to drive the flattening components 143 are directly disposed on the second support platform 144, and are arranged parallel to each other.

[0059] In addition, there are two film-applying units 140 arranged side by side to simultaneously bond two sets of release paper, improving overall work efficiency. Each film-applying unit 140 further includes a release paper storage assembly 146 for the film-applying adsorption assembly 142 to store the complete release paper in it for centralized storage. A base paper feeding assembly 147 is provided on the side of the two release paper storage stations away from the film-coating storage assembly 141. The base paper feeding assembly 147 includes an electric slide rail and a feeding tray movably arranged on the electric slide rail. The feeding tray is used to hold the cleaned base paper. The base paper feeding assembly 147 is arranged perpendicularly to the film-applying moving module 145 to enable the film-applying moving module 145 to quickly grasp and transfer the film.

[0060] Please refer to Figure 10 and Figure 12 The flattening assembly 143 further includes a support plate 1431 and a first positioning structure 14311 disposed on the support plate 1431 and capable of reciprocating along the plane of the support plate 1431; the support plate 1431 is further provided with a second positioning structure 14314 opposite to the first positioning structure 14311 for fixing the first side of the release paper, the first positioning structure 14311 for fixing the second side of the release paper opposite to the first side, and flattening the release paper under the movement of the first positioning structure 14311.

[0061] When in use, the flattening component 143 provides pulling power in front to pull the coating roll fixed on the roller, so that the coating roll moves forward to move above the support plate 1431. Under the pulling force, the coating is easily stretched in the pulling direction, resulting in its width being narrowed. Therefore, a first positioning structure 14311 that can pull the coating to move perpendicular to the pulling direction is adopted to counteract the pulling force on the coating in the pulling direction, so as to achieve flattening of coatings of different sizes. Its structure is ingeniously designed and easy to use.

[0062] Please refer to Figure 10 The support plate 1431 has a T-shaped groove for accommodating the first positioning structure 14311. The first positioning structure 14311 includes a strip-shaped adsorption plate 14312 and a first cylinder 14313. The T-shaped groove includes a strip-shaped groove portion for accommodating the strip-shaped adsorption plate 14312 and a square groove portion for accommodating the first cylinder 14313. The strip-shaped adsorption plate 14312 has several evenly distributed air extraction holes, specifically two rows of air extraction holes. The width of the strip-shaped adsorption plate 14312 is smaller than the width of the strip-shaped groove portion to reserve space for the movement of the strip-shaped adsorption plate 14312.

[0063] The T-slot structure can effectively limit and fix the first positioning structure 14311, ensuring that there is enough space to meet the movement of the strip adsorption plate 14312, so as to realize the action of horizontal flattening of the coating; at the same time, the way the strip adsorption plate 14312 adsorbs the coating is less likely to damage the coating surface.

[0064] Furthermore, the upper surface of the strip-shaped adsorption plate 14312 is flush with the upper surface of the support plate 1431 to further avoid damage to the coating surface and ensure the best adsorption effect.

[0065] Furthermore, the second positioning structure 14314 consists of several rows of air extraction holes on the support plate 1431, specifically two rows of air extraction holes. The arrangement direction of the air extraction holes is parallel to the length direction of the strip adsorption plate 14312, so as to cooperate with the first positioning structure 14311 to achieve stable adsorption on both sides of the coating film and to achieve flattening of the coating film.

[0066] Please refer to Figure 10 The support plate 1431 is further provided with a third positioning structure 14315, which is located between the first positioning structure 14311 and the second positioning structure 14314. The third positioning structure 14315 consists of several rows of air extraction holes, specifically ten to fifteen rows. The third positioning structure 14315 can effectively adsorb the main body of the coating film, ensuring that the coating film is stably adsorbed on the support plate 1431, thereby ensuring the fixation strength during subsequent cutting and preventing it from being torn away during cutting.

[0067] Please refer to Figure 11 The support plate 1431 has stepped grooves below the first positioning structure 14311, the second positioning structure 14314, and the third positioning structure 14315. Each stepped groove includes a connected fixing groove and a gas collecting groove. The fixing groove is used to detachably fix the suction plate 1432 by bolts. The suction plate 1432 has a vent hole. Due to the presence of the gas collecting groove, a gap is created between the suction plate 1432 and the suction hole. Since the gas collecting groove is connected to the suction hole, a negative pressure is formed through this gap to ensure a good suction effect. The vent hole is connected to an external air source for suction. Its structural design is simple and easy to manufacture.

[0068] Please refer to Figure 10 and Figure 11 The flattening assembly 143 further includes a cutting structure 1433 disposed on the lower surface of the support plate 1431. The cutting structure 1433 includes a lead screw 14331, a slider 14332 capable of reciprocating on the lead screw 14331, a cutting blade 14333 fixedly disposed on the slider 14332, a motor, and fixing seats 14334 fixing both ends of the lead screw 14331. The cutting blade 14333 is disposed on one side edge of the support plate 1431 for cutting the release paper along the direction perpendicular to the feed direction of the release paper. Using this cutting structure 1433 can effectively achieve rapid cutting of the coating in the flattened release paper.

[0069] Please refer to Figure 10 The flattening assembly 143 further includes a pre-compression structure 1434 disposed on the support plate 1431. The pre-compression structure 1434 includes a third cylinder 14341, a connecting part 14342, and a pre-compression wheel set 14343 disposed on the connecting part 14342. The pre-compression wheel set 14343 includes two rotatable rollers 14344 and a rubber ring 14345 wrapped around the two rollers 14344. The pre-compression wheel set 14343 is disposed on one side of the second positioning structure 14314 and close to the cutting blade 14333.

[0070] The transfer mechanism 3 includes a fixed bracket, an electric slide rail mounted on the fixed bracket, and a transfer gripping assembly. The transfer gripping assembly is located at the end of the upper moving track 30. The defective product area 150 is located on one side of the end of the upper moving track 30 and is used to store the bottom paper that has failed to meet cleaning standards.

[0071] The structure of the pre-pressure wheel set 14343 can effectively ensure that the pre-pressure wheel set 14343 can press the coating on one side before the cutting structure 1433 cuts, through the push of the third cylinder 14341 and the pre-pressure wheel set 14343. This avoids the cutting blade 14333 from directly tearing the coating off during cutting. Its structure is ingenious and easy to use.

[0072] Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 9 A control method for a fully automatic release paper cleaning and laminating equipment, used to control the laminating equipment, includes the following steps:

[0073] S1: The release paper to be cleaned is adsorbed and fixed on the release paper fixing tray 20, and the release paper fixing tray 20 is controlled to move on the lower moving track 40 and pass under the first blowing component 60 to clean the upper surface of the release paper. After cleaning, the first shooting camera group 90 and the first light source component 80 are used to take pictures to detect whether it is clean.

[0074] S2: The movable adsorption component 50 moves along the upper moving track 30 to the end of the lower moving track 40 to adsorb the bottom paper, and suspends the adsorbed bottom paper to pass above the second blowing component 70 to clean the lower surface of the bottom paper. After cleaning, the second shooting camera group 110 and the second light source component 100 take pictures to detect whether it is clean.

[0075] S3: First, pull the end of the coating roll located on the coating and paper storage assembly 141 to the flattening assembly 143 away from the coating and paper storage assembly 141 and adsorb and fix the coating. At the same time, the flattening assembly 143 close to the coating and paper storage assembly 141 adsorbs the coating body.

[0076] S4: The transfer mechanism 3 transfers the cleaned backing paper to the coated paper storage assembly 141 or the defective product area 150, wherein the backing paper transferred to the defective product area 150 is the backing paper that failed the test in steps S1 and S2; the film adsorption assembly 142 adsorbs the backing paper in the coated paper storage assembly 141 onto the coating of the flattening assembly 143, thereby achieving the adhesion of the coating and the backing paper to form a complete release paper;

[0077] S5: After lamination, the cutting structure 1433 of the flattening component 143 at the end of the adsorption coating cuts the release paper and controls the flattening component 143 to not adsorb the release paper so that the film adsorption component 142 can transfer the release paper for storage.

[0078] S6: The flattening component 143 adsorbing the coating body moves horizontally to continue stretching the coating. The flattening component 143, which originally adsorbed the end of the coating, moves downward along a clockwise square-shaped trajectory, then horizontally, and then upward to the position of the coating body to adsorb the coating body.

[0079] S7: Repeat steps S1, S2, and S4~S6 to achieve batch bonding and cutting of release paper.
