[0002] Currently, touch panels are used in electronic devices, remote controls, and home appliances. These touch panels all have push-buttons, and the outer surface of these push-buttons is marked with text, numbers, or symbols. The outer surface layer is made of PET roll material. In the existing technology, the printed PET roll material is cut into individual sheets, and the double-sided tape is also punched into individual sheets. Then, the holes of the double-sided tape are manually cleaned to remove waste. Then, the release paper on the single double-sided tape sheet with the waste is peeled off, and then it is manually aligned and pasted with the PET sheet with the printed pattern. This process requires multiple manual steps to complete, which is not only cumbersome and inefficient, but also results in poor alignment accuracy. Summary of the Invention

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Reference Figures 1 to 12As shown, this embodiment of the invention provides a CCD bonding machine, including a mounting platform 1, a double-sided adhesive feeding rack 2, a bonding machine body 3, a bonding assembly 4, and an alignment assembly 5. The double-sided adhesive feeding rack 2 is located beside the mounting platform 1 and is used for feeding roll double-sided adhesive. The bonding machine body 3 is horizontally arranged and is used for feeding, aligning, and discharging roll double-sided adhesive. A waste collection roller 38 is provided above the bonding machine body 3. The bonding assembly 4 is located beside the bonding machine body 3 and is used to adsorb and move PET sheets onto the bonding machine body 3 to achieve PET sheet feeding. The alignment assembly 5 is located beside the bonding assembly 4. Located beside the discharge end of the bonding machine body 3, the alignment component 5 includes an alignment platform 51, an alignment moving structure 52, and a downward pressure de-bubbling structure 53. The alignment platform 51 is horizontally arranged on the top of the mounting platform 1. The alignment moving structure 52 is located on the alignment platform 51. The alignment moving structure 52 is provided with a moving calibration structure 54, which faces the bonding machine body 3. The downward pressure de-bubbling structure 53 is located beside the moving calibration structure 54 and is used to remove bubbles when bonding PET sheets. A CCD die-cutting machine 7 is also provided beside the bonding machine body 3 to enable die-cutting after bonding is completed.

[0039] In use, the double-sided adhesive roll is unwound and fed by the double-sided adhesive unloading rack 2. The double-sided adhesive roll passes through the feeding conveyor roller 33 on the main body 3 of the bonding machine. The release paper on the double-sided adhesive roll is wound up by the waste collection roller 38. Then, the double-sided adhesive roll is conveyed forward by the automatic feeding conveyor belt 31. During the conveying process, the double-sided adhesive roll is detected by the digital color mark sensor 37.

[0040] The PET sheet is then picked up and moved onto the roll double-sided adhesive by the main body 3 of the applicator. The main body 3 then aligns and calibrates the PET sheet and the roll double-sided adhesive to ensure they are aligned. The PET sheet is then applied to the roll double-sided adhesive, thus achieving automatic applicator operation. After the PET sheet and roll double-sided adhesive are aligned and bonded, the roll is fed into the CCD die-cutting machine 7. The CCD die-cutting machine 7 automatically punches out the shape of the bonded roll and then cuts it into individual finished products by the slicing mechanism at the rear of the CCD die-cutting machine 7. The entire set of equipment can realize the integrated operation of feeding, applicator, and die-cutting, improving work efficiency.

[0041] Specifically, refer to Figure 4As shown, the main body 3 of the adhesive tape applicator includes a horizontally arranged automatic feeding conveyor belt 31, which can drive the double-sided adhesive tape to move forward. The feeding end of the automatic feeding conveyor belt 31 is provided with a feeding rack 32, and a feeding conveying roller 33 is provided on the side of the feeding rack 32. The waste collection roller 38 is located above the feeding rack 32. The discharging end of the automatic feeding conveyor belt 31 is also provided with a discharging roller group 34. The automatic feeding conveyor belt 31 is also provided with a photoelectric sensor frame 35, and the photoelectric sensor frame 35 is provided with a photoelectric sensor slider 36. The photoelectric sensor slider 36 is provided with a digital color mark sensor 37.

[0042] In this embodiment, the roll double-sided adhesive is conveyed forward through the feed rack 32 to the feed conveyor roller 33, and then conveyed to the area below the photoelectric sensor frame 35 by the feed conveyor belt. The position of the digital color mark sensor 37 can be moved by moving the photoelectric sensor slider 36 to detect the printing material of the roll double-sided adhesive, so as to ensure the accurate alignment and bonding of the PET sheet and the roll double-sided adhesive.

[0043] Specifically, refer to Figure 5 As shown, the bonding component 4 includes a sheet feeding structure 41 and a sheet moving structure 42. The sheet feeding structure 41 is located beside the mounting platform 1, and the sheet moving structure 42 is located above the automatic feeding conveyor belt 31. The sheet moving structure 42 is connected to the sheet feeding structure 41.

[0044] Specifically, refer to Figure 6 and Figure 7 As shown, the sheet feeding structure 41 includes a feeding motor 412, a feeding screw 413, a feeding frame 414, and a feeding moving frame 415. The feeding frame 414 is vertically arranged, the feeding motor 412 is located on the feeding frame 414, the bottom of the feeding screw 413 is rotatably connected to the feeding frame 414, and the feeding motor 412 is drive-connected to the feeding screw 413. The feeding moving frame 415 is threadedly connected to the feeding screw 413 and moves up and down on the feeding frame 414. The feeding moving frame 415 is located in the hopper for stacking PET sheets, and the feeding moving frame 415 can stack PET sheets one by one on the feeding moving frame 415 for subsequent use.

[0045] In this embodiment, when feeding PET sheets, the PET sheets are stacked on top of the feeding moving frame 415. Then, the feeding motor 412 drives the feeding screw 413 to rotate on the feeding rack 414, which causes the position of the feeding moving frame 415 to move upward. When a PET sheet is picked up by the sheet moving structure 42, the feeding moving frame 415 will move upward to move the next PET sheet upward to below the alignment suction cup 424 for picking up. The sheet feeding structure 41 can realize the automatic feeding operation of PET sheets.

[0046] Specifically, refer to Figure 8 As shown, the sheet moving structure 42 includes a horizontal moving slide 421, a lifting cylinder 422, a slide block 423, and a positioning suction cup 424. The horizontal moving slide 421 is mounted above the automatic feeding conveyor belt 31. The slide block 423 is connected to the moving end of the horizontal moving slide 421. The lifting cylinder 422 is located on the slide block 423. The positioning suction cup 424 is located on the telescopic end of the lifting cylinder 422.

[0047] In this embodiment, when the PET sheet is being picked up and moved, the horizontal moving slide 421 moves the position of the slide block 423 above the feeding moving frame 415. Then, the lifting cylinder 422 moves the alignment suction cup 424 above the PET sheet to pick up the PET sheet. After that, the horizontal moving slide 421 moves the position of the slide block 423 above the automatic feeding conveyor belt 31. The lifting cylinder 422 moves the alignment suction cup 424 downward to place the picked-up suction cup above the material support plate 6. This enables automatic feeding of the PET sheet.

[0048] The PET sheet is placed on the support plate 6 such that most of the PET sheet is placed horizontally on the support plate 6, and a smaller portion of the PET sheet is placed loosely on the support plate 6 to facilitate subsequent adjustment of the PET sheet's position.

[0049] Specifically, the movable calibration structure 54 includes a support frame 541, a bidirectional lead screw slide 542, two vertical slides 543, and two CCD cameras 544. The support frame 541 is horizontally mounted on the mounting platform 1. The bidirectional lead screw slide 542 is horizontally mounted on top of the support frame 541. The two vertical slides 543 are respectively connected to the two moving ends of the bidirectional lead screw slide 542, and the two CCD cameras 544 are respectively connected to the moving ends of the two vertical slides 543. The alignment movable structure 52 includes a horizontal electric movable slide 521. A movable frame 522 is provided on the horizontal electric movable slide 521. Two clamping cylinders 523 are provided on the movable frame 522. The telescopic ends of the two clamping cylinders 523 are equipped with... A horizontally positioned lower pressure plate 524 has a non-stick bottom. The lower pressure de-aeration structure 53 includes a connecting frame 531, a lower pressure cylinder 532, and a de-aeration cylinder 533. The connecting frame 531 is horizontally positioned on the side wall of the support frame 541. A lower pressure frame 534 is slidably fitted on the connecting frame 531. The lower pressure cylinder 532 is vertically positioned on the top of the connecting frame 531, and its telescopic end is connected to the lower pressure frame 534. The de-aeration cylinder 533 is horizontally positioned on the lower pressure frame 534. A movable frame 535 is slidably fitted on the lower pressure frame 534. The movable frame 535 is connected to the telescopic end of the de-aeration cylinder 533. A movable roller 536 is rotatably connected to the movable frame 535.

[0050] In this embodiment, the double-sided tape is a pre-punched roll, and the printed PET is a PET sheet. The roll of double-sided tape is fed through an independent double-sided tape feeding rack, and then, through the main body of the laminating machine, the release paper on the double-sided tape is peeled off by the waste collection roller 38, exposing the adhesive surface of the double-sided tape. Two CCD cameras 544 take the first photograph of the double-sided tape. Simultaneously, the entire stack of printed PET sheets is separated into individual sheets by the laminating assembly, and then moved to the material support plate 5. Two clamping cylinders 523 move downwards simultaneously, causing the lower pressure plate 524 to move downwards, pressing and fixing the PET sheets. Since the PET sheets are above the double-sided tape and have a 10mm diameter... Due to the height difference of approximately m, the CCD camera 544 needs to be raised by 10mm. This is achieved by moving the positions of the two vertical slides 543 upwards by 10mm, which in turn moves the CCD camera 544 upwards by 10mm. Then, the two CCD cameras 544 take a second picture of the PET sheet. After the first and second pictures of the double-sided adhesive are taken, CCD calculations are performed, and the alignment platform 51 drives the alignment moving structure 52 to align and calibrate the PET sheet and the roll double-sided adhesive, ensuring that the printing material on the PET sheet and the holes on the roll double-sided adhesive are aligned.

[0051] After that, the pressing cylinder 532 works to drive the pressing frame 534 to move downward on the connecting frame 531, moving the position of the pressing frame 534 to the PET sheet on the material support plate 6, so that the moving roller 36 abuts against the top of the PET sheet.

[0052] Then, the horizontal moving slide 421 drives the moving frame 522 to move. The direction of movement is to move one distance in the downward material direction. During the movement, firstly, it can remove air bubbles from the PET sheet and roll double-sided tape that are stuck together, and secondly, it can make the PET sheet and roll double-sided tape stick together more firmly.

[0053] While the lower pressure plate 524 moves, the de-bubble cylinder 533 operates, causing the moving frame 535 to move horizontally. The horizontal movement of the moving frame 535 causes the moving roller 36 to rotate. As the moving roller 36 rotates, the automatic feeding conveyor belt 31 operates, moving the roll double-sided adhesive forward, thus moving the PET sheet onto the forward-moving roll double-sided adhesive. The rotation of the moving roller 36 serves two purposes: firstly, it removes air bubbles from the mutually adhered PET sheet and roll double-sided adhesive; secondly, it moves the PET sheet forward, allowing the PET sheet and roll double-sided adhesive to be fully bonded. During the bonding process, the two clamping cylinders 523 operate simultaneously, causing the lower pressure plate 524 to move upward, providing space for the movement of the PET sheet and roll double-sided adhesive.

[0054] This device enables the calibration and movement of the PET sheet position during the bonding process of PET sheets to roll double-sided adhesive, ensuring precise bonding of the PET sheet onto the roll double-sided adhesive. It also removes air bubbles generated during the bonding process, improving the quality of PET sheet bonding.

[0055] Specifically, a material support plate 6 is provided on the automatic feeding conveyor belt 31 and below the lower pressure frame 534. After the PET sheet is moved over by the sheet moving structure 42, one end of the PET sheet is placed on the material support plate 6 and the other end is placed on the roll double-sided adhesive. The bottom of the material support plate 6 is an anti-sticking layer, so that the roll double-sided adhesive will not stick to the bottom of the material support plate 6.

[0056] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
