Description

Technical Field

[0001] This utility model belongs to the field of laminating machine technology, and in particular relates to an automatic laminating machine. Background Technology

[0002] Lamination is widely used in electronic products, packaging products, and decorative materials. In current set-top box surface treatment processes, the purpose is to cover the outer surface of the set-top box with a protective or decorative film to improve the product's wear resistance, scratch resistance, or aesthetics. Most existing lamination equipment still relies on manual assistance for film handling, positioning, and cutting. For example, the roll of film is manually pulled out and initially positioned on the product surface, then laminated by a pressing mechanism. This method is not only inefficient and labor-intensive, but also prone to wrinkles or misalignment due to misalignment, affecting lamination quality. While some automated equipment has basic film conveying and cutting functions, its overall structure is loose, and the coordination between components is poor. The film is prone to deviation or stretching deformation during feeding, tensioning, cutting, and transfer. In particular, it lacks a precise limiting and rapid cutting integrated design for the film, resulting in low film utilization and unstable lamination accuracy. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0023] In one embodiment of this utility model, an automatic laminating machine is used to cover the surface of a product with an adhesive film, characterized in that it includes a base 100. A conveying assembly 200, mounted on a base 100, is used to convey products. The feeding assembly 300 is vertically mounted on the base 100 and located on one side of the conveying assembly 200 for conveying the adhesive film; The worktable 110 and the feeding assembly 300 include a support plate 310. The support plate 310 has a worktable 110 and a limiting unit 400 arranged along the Y-axis on one side. The limiting unit 400 is located on the worktable 110 and is used to limit the adhesive film on the worktable 110. The film-taking mechanism 500 includes a clamping component 510, a cutting component 520, and a translation component 530. The translation component 530 is mounted on the support plate 310, and the output end of the translation component 530 is provided with the clamping component 510 to drive the clamping component 510 to move back and forth along the X-axis. The output end of the clamping component 510 is disposed opposite to the limiting unit 400 to clamp the adhesive film on the limiting unit 400. The cutting component 520 is also provided below the worktable 110. The cutting component 520 moves back and forth along the Y-axis to cut the adhesive film clamped by the clamping component 510. The pressing component 600 is mounted on the base 100, and its driving end is connected to an adsorption unit 630 for adsorbing the cut adhesive film, so as to drive it to rise or press down.

[0024] Specifically, 1. First, the film roll is placed on the feeding assembly 300, and the end of the film is precisely fixed on the worktable 110 by the limiting unit 400. Then, the film taking mechanism 500 starts working: the translation assembly 530 drives the clamping assembly 510 to move along the X-axis to above the worktable 110, so that the output end of the clamping assembly 510 is aligned with the end of the film on the limiting unit 400. 2. Next, the clamping assembly 510 moves to firmly clamp the end of the film; then, the translation assembly 530 drives the clamping assembly 510 to move in the opposite direction along the X-axis, pulling the film out of the roll and laying it flat for a predetermined length to cover the conveying assembly 200. 3. When the film is pulled out to the set length, the pressing assembly 600 starts to move, and the adsorption unit 630 (usually a plate with a vacuum suction cup) at its driving end descends to contact the upper surface of the cut film and firmly picks it up through vacuum adsorption. 4. Next, the cutting component 520 starts, moving along the Y-axis from below the worktable 110, cutting the flat adhesive film from the roll like scissors. 5. Simultaneously, the conveying component 200 has transported the product to be coated to the precise position directly below the section of adhesive film. 6. The pressing component 600 then drives the adsorption unit 630 to move downwards a second time, carrying the adhesive film, precisely pressing it onto the surface of the positioned product. Finally, the adsorption unit 630 breaks the vacuum, releases the adhesive film, and returns to its initial position, ready for the next cycle. The coated product is then conveyed out by the conveying component 200, thus completing a full automated coating process.

[0025] Furthermore, the conveying assembly 200 includes a conveyor frame 210, a conveyor motor 220, and a conveyor belt 230. The conveyor frame 210 is mounted on the base 100. Both the conveyor motor 220 and the conveyor belt 230 are mounted on rollers 240 of the conveyor frame 210. The drive end of the conveyor motor 220 is connected to the rollers 240 to drive the conveyor belt 230 to rotate. Specifically, the conveyor motor 220 starts upon receiving a command from the control system, driving the rollers 240 connected to it to rotate via its drive end. The rotation of the rollers 240, in turn, drives the conveyor belt 230, which is wrapped around the conveyor frame 210, to circulate. Products placed on the conveyor belt 230 are precisely conveyed to the laminating station, directly below the film, as the conveyor belt 230 moves. When the product reaches the predetermined position, the conveyor motor 220 stops or remains in standby mode to ensure that the product remains stationary during the laminating process. After the lamination process is completed, the conveyor motor 220 is restarted to smoothly deliver the laminated product and simultaneously feed in the next product to be processed, achieving continuous operation. Specifically, the conveyor frame 210 includes a first positioning frame 211, a movable frame 213, and a second positioning frame 212. The first positioning frame 211 and the second positioning frame 212 are both arranged on the base 100 along the Y-axis direction. A fixed arm 214 is connected between the first positioning frame 211 and the second positioning frame 212. The fixed arm 214 is equipped with a movable movable frame 213. A threaded handle 215 includes a threaded part 216 and a handle 217 fixedly connected thereto. The threaded part 216 passes through the first positioning frame 211, the movable frame 213, and the second positioning frame 212 in sequence. The threaded handle 215 drives the movable frame 213 to move back and forth along the Y-axis direction. A conveyor baffle 218 is provided between the movable frame 213 and the second positioning frame 212. Specifically, the threaded handle 215 drives the moving frame 213 to move precisely along the Y-axis between the first positioning frame 211 and the second positioning frame 212 along the guide of the fixed arm 214, thereby changing the relative distance between the moving frame 213 and the second positioning frame 212, making the width between the two conveying baffles 218 adjustable, and ensuring that the product will not fall off when entering the coating station.

[0026] Furthermore, the feeding assembly 300 includes a movable roller 320 and several traction rollers 330. The movable roller 320 and traction rollers 330 are mounted on the support plate 310. The film roll is sleeved on the movable roller 320. A section of film is pulled out of the film roll, passes around the several traction rollers 330, and reaches the limiting unit 400. The limiting unit 400 includes a limiting cylinder 410 mounted on the support plate 310. The driving end of the limiting cylinder 410 is connected to the limiting member 420 to drive the limiting member 420 to perform lifting and lowering movements. The limiting member 420 presses the film flat onto the worktable 110. The base 100 is provided with a guide rod 340, which is provided with a screw 350 and a handle 360 ​​on its top. The support plate 310 is connected to the screw 350. Rotating the handle 360 ​​causes the support plate 310 to move along the direction of the guide rod 340. The translation assembly 530 includes a translation cylinder 531 mounted on the back of the support plate 310. The drive end of the translation cylinder 531 is connected to the translation plate 532, driving the translation plate 532 to move back and forth along the X-axis. Specifically, the film roll is sleeved on the movable roller 320. The operator or robot pulls out the film head, allowing it to pass around several traction rollers 330, forming a specific path before reaching the worktable 110 and being initially fixed by the limiting unit 400. During the feeding process, the traction rollers 330 guide and maintain the tension of the film. When it is necessary to fix the film for retrieval, the limiting cylinder 410 actuates, driving the limiting member 420 at its drive end to descend, pressing the end of the film flat against the surface of the worktable 110, providing a stable clamping point for the clamping assembly 510. The height adjustment of the entire feeding assembly 300 is achieved by manually rotating the handle 360 ​​on the base 100. The handle 360 ​​drives the screw 350 to rotate. Since the support plate 310 is connected to the screw 350 and is restricted to moving up and down by the guide rod 340, the rotational movement of the screw 350 is converted into the precise lifting and lowering of the support plate 310.

[0027] Furthermore, the clamping assembly 510 includes a clamping cylinder 511, which is mounted on the translation plate 532. The drive end of the clamping cylinder 511 is connected to the clamping part 512 to control the opening and closing of the clamping part 512 for clamping the adhesive film. The cutting assembly 520 includes a cutting cylinder 521 mounted below the worktable 110. The drive end of the cutting cylinder 521 is connected to the cutting member 522 to drive the cutting member 522 to move back and forth along the Y-axis. When film removal is required, the translation assembly 530 has already transported the clamping assembly 510 to the position above the worktable 110 corresponding to the end of the adhesive film. Then, the clamping cylinder 511 actuates, driving the clamping part 512 (such as a gripper) at its output end to close, thereby firmly clamping the end of the adhesive film pressed onto the worktable 110 by the limiting member 420. After clamping is completed, the translation assembly 530 moves the clamping assembly 510 to pull out the adhesive film. When cutting is required, the cutting cylinder 521 located below the worktable 110 is activated, driving the cutting component 522 (such as a blade) connected to its output end to quickly and smoothly pass through the entire width of the adhesive film along the Y-axis, thereby completing the cutting. It should be noted that a certain distance is maintained between the cutting component 522 and the limiting component 420, so that a section of the adhesive film end protrudes outward after each cut, so that the clamping part 512 can grasp it.

[0028] Furthermore, the pressing assembly 600 includes a column 610 mounted on the base 100, a horizontal plate 611 mounted on the column 610, and a double-stroke cylinder 620 mounted on the horizontal plate 611. The drive end of the double-stroke cylinder 620 is connected to the adsorption unit 630 to drive the adsorption unit 630 to press down to the first point where the adhesive film is about to be cut, and to the second point where it is pressed down to the surface of the product. The adsorption unit 630 includes an adsorption plate 632 and adsorption disks 631 arranged around it. The adsorption disks 631 are used to pick up the adhesive film. Specifically, initially, the drive end of the cylinder is at the initial point. After the adhesive film is cut, the first stroke of the double-stroke cylinder 620 is activated, driving the adsorption unit 630 to descend to a preset "first point". This position is the height at which the adsorption disks 631 on the adsorption unit 630 can just contact and pick up the flat adhesive film without causing it to deform significantly. The adsorption disks 631 (usually connected to a vacuum system) generate negative pressure, firmly adsorbing the adhesive film onto the adsorption plate 632. Subsequently, the second stroke of the dual-stroke cylinder 620 is initiated, driving the adsorption unit 630, which has already adhered to the adhesive film, to continue descending to the "second position," i.e., the product surface, completely pressing the adhesive film onto the product. After completion, the vacuum is released, and the cylinder drives the adsorption unit 630 back to its original position.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
