Abstract
Description
Technical Field
[0001] This utility model relates to the field of touch screen composites, specifically a rigid touch screen composite device. Background Technology
[0002] A touchscreen is a device that controls circuits by sensing changes in electrical signals generated when a person touches or approaches it. Based on their working principle, they are mainly divided into two categories: capacitive sensing and resistive sensing. Based on their material, they are divided into flexible touchscreens and rigid touchscreens. The main difference lies in the material of the panel. Rigid touchscreens primarily use acrylic or glass panels, with a conductive film laminated onto the rigid panel. The rigid panel has corresponding switch patterns, and the conductive film has circuits corresponding to the switches. When a finger presses a switch on the rigid panel, it controls whether the circuit on the conductive film is conducting, thereby controlling the various functions of the appliance to turn on or off.
[0003] In traditional rigid touch screen manufacturing, the conductive film is laminated onto the rigid panel manually, one sheet at a time. This manual lamination process is inaccurate and requires manual alignment of the circuitry on the conductive film with the patterns on the rigid panel, resulting in low production efficiency for rigid touch screens.

[0032] The clamping assembly 2 includes two symmetrically arranged conveying mechanisms. The two conveying mechanisms are used to clamp the rigid panel and can simultaneously convey and position the rigid panel. The distance between the two conveying mechanisms is adjustable.

[0037] The clamping assembly 2 has two symmetrical support seats 11 on both the front and rear sides. Two movable blocks 27 are arranged between the support seats 11 on both the front and rear sides. The four movable blocks 27 are fixed to the lower end faces of the two horizontal rods 20 respectively. The support seats 11 on both the front and rear sides are rotatably connected by a screw 12 that passes through the movable blocks 27. The screw 12 is threadedly connected to the movable blocks 27. The screws on the front and rear sides of the movable blocks 27 have opposite directions of rotation. A first guide rod 13 is arranged on the lower side of the screw 12 that passes through the movable blocks 27. The first guide rod 13 is slidably connected to the movable blocks 27. The first guide rod 13 is arranged parallel to the screw 12 and perpendicular to the horizontal rods 20.
[0038] The first extension block 31 has guide strips 37 fixed on both its left and right sides, and the second extension block 32 has a guide groove 36 on the side near the guide strips 37. The guide strips 37 and the guide grooves 36 are slidably connected.
[0039] The rotating roller includes two symmetrical support rods 42. Both ends of the side plate 30 are fixed with pneumatic cylinders 41. The pneumatic cylinders 41 pass through the support rods 42 and are rotatably connected to the support rods 42. On the side of the support rods 42 on the front and rear sides that are close to each other, multiple brackets 40 are fixed around the pneumatic cylinders 41. The brackets 40 on the two support rods 42 are staggered and are slidably connected to each other.
[0040] A second guide rod 33 is fixed on the side plate 30 where the second extension block 32 is fixed, passing through the first extension block 31. The second guide rod 33 is slidably connected to the first extension block 31.
[0041] A fixing seat 43 is provided on the upper side of the pressing component 3. A connecting plate 44 is fixed on the upper end face of the fixing seat 43. Positioning plates 34 are provided on both the left and right sides of the fixing seat 43.

[0043] In use, the unwinding device unfolds the rolled plastic film, and the plastic film passes under the pressing assembly 3 and is then wound up by the winding device.
[0044] The conductive film moves to the underside of the pressing assembly along with the plastic film.
[0045] At the same time, the motor 23 starts, causing the axle 25 to rotate, which in turn drives the pulley 26 to rotate, thereby causing the conveyor belt 21 to rotate. The rigid panel coated with glue is then inserted into the conveyor groove 22 on the front and rear sides of the conveyor belt 21. As the conveyor belt 21 rotates, the rigid panel is conveyed to the area directly below the pressing assembly 3. At this point, the unwinding device and the winding device stop rotating, and the motor 23 is turned off.
[0046] At this time, the pneumatic cylinder 41 extends, and the pressing component 3 presses down on the plastic film, thereby pressing the conductive film onto the rigid panel. The adhesion between the conductive film and the rigid panel is greater than that between the conductive film and the plastic film. Then the pneumatic cylinder 41 shortens, and the pressing component 3 rises accordingly, so that the film moves away from the conductive film. At this time, the composite of the conductive film and the rigid panel is completed.
[0047] Then, restart the unwinding device, the winding device, and the motor 23, and repeat the above process to improve the composite efficiency of the rigid touch screen.
[0048] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
