[0002] As the level of automotive intelligence continues to increase, the application of automotive touch panels is becoming more and more widespread. Automotive touch panels are typically composed of components such as cover glass and touch sensor glass bonded together. Currently, there are many problems in the bonding process of automotive touch panels.

[0003] The current bonding process is as follows: First, the sensor is manually placed on a positioning fixture, then the panel is placed in another fixture, the bonding equipment is started, and the bonding position is visually inspected. The same process is then repeated to bond the diffuser sheet, foam, frame adhesive, and LCD to the panel. This requires both machine and manpower for bonding each component. The numerous bonding steps and long process result in more scratches and scrap. Furthermore, the equipment lacks visual alignment, leading to low bonding accuracy, large cumulative tolerances, and significant fluctuations in product quality.

[0034] Working principle: In this embodiment, the present invention also proposes a method for using a fully automatic bonding system for automotive touch panels, including the following steps:

[0035] Step 1: First, power on the device, then turn on the first motor 5, the first electric push rod 12, the second electric push rod 14, the second motor 19, the third motor 20, the first cylinder 26, the fourth motor 30, the linear motor 37, the fifth motor 41, the sixth motor 45, and the third cylinder 60 respectively.

[0036] Step 2: The first motor 5 inside the base 1 operates, driving the turntable 2 to rotate around the center. The support ring 6 helps maintain the rotational stability of the turntable 2, so that multiple positioning molds 3 are sequentially transferred to each work station. The positioning molds 3 are used to carry the relevant components of the automotive touch panel. The positioning groove 7 of the contour pressing mechanism is initially adapted to the shape of the component, and the subsequent contour pressing action can further fix it accurately.

[0037] Step 3, taking a material conveying mechanism as an example, the fourth motor 30 drives the take-up roller 31 to rotate, which, together with the unwind roller 32, realizes the unwinding of materials (such as film materials to be laminated). The first guide roller 34, the second guide roller 35, and the third guide roller 36 work together to adjust the material direction and tension to ensure that the material is conveyed flat. The linear motor 37 of the linear module 29 drives the lifting plate 38 and the pressure plate 39 to move, which can assist in pressing and positioning the material. At the same time, the vision system (which, combined with the position layout of the mechanism, can realize the identification of material feature points) collects the position information of the components on the positioning mold 3 and the conveyed material, providing coordinate reference for subsequent lamination and compensating for mechanical errors.

[0038] Step four: The first electric push rod 12 extends and retracts, and through the hinge structure of the first auxiliary plate 9 and the second auxiliary plate 11, it drives the sealing plate 10 to finely adjust the angle; the second electric push rod 14 extends and retracts, and through the linkage of the first connecting rod 15 and the second connecting rod 16, it controls the lifting and lowering of the sealing plate 10 and the mold 13. The mold 13 is adapted to the positioning groove 7 to perform contour pre-pressing on the placed parts to ensure the accurate posture and position of the parts before bonding. The second motor 19 and the third motor 20 drive the first lead screw 21 and the second lead screw 22 to rotate respectively. The first mounting block 23 (fixed to the second mounting plate 18) and the second mounting block 25 move along the lead screw. The guide plate 24 cooperates with the guide groove to ensure smooth movement. The first cylinder 26 extends and retracts, driving the U-shaped positioning frame and the pressure roller 27 to press down. The pressure roller 27 can roll along the set trajectory to apply force evenly to the bonding surface and strengthen the bonding firmness.

[0039] Step 5: The fifth motor 41 drives the third lead screw 42 to rotate, causing the third mounting block 43 to move along the guide rod 40. This drives the third mounting plate 44, the sixth motor 45, and the lower film-tearing assembly, LCD patch assembly, and positioning camera 47 to move synchronously, achieving multi-station operation coverage. The second cylinder 48 extends and retracts to adjust the height of the film-tearing assembly. The seventh motor 49 drives the fourth lead screw 50 to rotate, causing the lifting block 54 to rise and fall along the mounting cylinder 51. Through the linkage of the third connecting rod 52 and the fourth connecting rod 53, the opening and closing of the third auxiliary plate 55 and the clamping needle 56 are controlled. The clamping needle 56 grips the edge of the film material, and the inclined section of the push block 57 assists in separating the film material from the edge. At the same time, the suction cup 59 reaches above the TRAY plate 65. At this time, the sixth motor 45 drives the fourth mounting plate 46 to rotate, changing the position of the film peeling assembly and the LCD patch assembly. At this time, the film peeling assembly is located directly above the waste trough 61, and the waste falls into the waste trough 61 below. The air pump 58 draws air to generate negative pressure in the suction cup 59. The third cylinder 60 extends and retracts to control the suction cup 59 to pick up the LCD material conveyed by the material bin 62 through the TRAY plate 65, the I-shaped guide rail 63, and the slider 64. According to the precise coordinates fed back by the positioning camera 47, the LCD is attached to the corresponding position of the touch panel. After all the attachments are completed, the power is turned off.
