Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 5 As shown, this utility model provides a glue coating machine for touch screen production, including a support structure 1. The support structure 1 includes a support base 11, a limiting seat 12, a first collection box 13, a slide 14, an optical axis 15, a drive motor 16, a lead screw 17, and a moving seat 18. The slide 14 and the optical axis 15 are each provided with two sets. The two sets of slide 14 are opened inside the upper surface of the support base 11 on both sides. The clamping structure 2 includes a support plate 21, a threaded plate 211, and a locking screw 212. Both the threaded plate 211 and the locking screw 212 are provided in two sets. Both ends of the lower surface of the support plate 21 are fixedly connected to the connecting plate 22. The lower ends of the two sets of connecting plates 22 are fixedly connected to the upper surface of the movable seat 18. Both ends of the upper surface of the support plate 21 are provided with connecting grooves 25. Both sets of connecting grooves 25 are provided with slides 29. The upper ends of the two sets of slides 29 are fixedly connected to the clamping plate 28. The bearing in the middle of the lower surface of the support plate 21 is connected to the gear 27. Limit rods 26 are fixedly connected to the surfaces of the two sets of connecting plates 22 on opposite sides. Racks 210 are fixedly connected to the surfaces of the two sets of slides 29 on one side. The adhesive coating structure 3 includes a support base 31, a glue roller 35, and an adhesive coating plate 36. The support base 31 is fixedly connected to the upper surfaces of both sides of the support base 11.

[0019] The limiting seat 12 is fixedly connected to the upper surface of the middle position of the support base 11, and the first collection box 13 is engaged inside the limiting seat 12. The position of the first collection box 13 is perpendicular to the position of the roller 35.

[0020] The first collection box 13 can collect the glue dripping from the glue roller 35. This design can effectively prevent excess glue from adhering to the upper surface of the support base 11. The length of the first collection box 13 is 50-100mm longer than the length of the glue roller 35, ensuring that the glue dripping from both ends of the glue roller 35 can be completely collected.

[0021] Two optical axes 15 are fixedly connected to both sides inside the support base 11, the drive motor 16 is installed on the outer surface of one end of the support base 11, the lead screw 17 is connected to the inside of the support base 11 by a bearing, and the output shaft of the drive motor 16 is fixedly connected to one end of the lead screw 17.

[0022] By starting the drive motor 16, the lead screw 17 can be driven to rotate inside the support base 11. Both ends of the lead screw 17 are provided with bushings, and the bushings are fixedly connected to the inner surface of the support base 11. The bushings can effectively improve the stability of the lead screw 17 during rotation.

[0023] The movable seat 18 is located inside the support base 11. The interior of both ends of the movable seat 18 is slidably connected to two sets of optical axes 15, and the lead screw 17 is threadedly connected to the interior of the movable seat 18 in the middle position.

[0024] The rotation of the lead screw 17 can drive the movable seat 18 to move inside the support base 11. The clearance between the movable seat 18 and the optical axis 15 is 0.02-0.05mm. The sliding surface is coated with lithium-based grease, which is replenished every 500 hours. The two sets of optical axes 15 can limit the movement of the movable seat 18, preventing it from shaking or rotating during movement, and effectively improving the stability of the movable seat 18 during movement.

[0025] Two sets of connecting plates 22 are slidably connected to the inside of two sets of sliding grooves 14, and a fixed seat 23 is fixedly connected to one side of the support plate 21, and a second collection box 24 is provided inside the fixed seat 23.

[0026] The two sets of connecting plates 22 enable the moving base 18 to move synchronously with the clamping structure 2 when it moves. The two sets of sliding grooves 14 can limit the movement of the two sets of connecting plates 22, thereby improving the stability of the two sets of connecting plates 22 when they move. The second collection box 24 can collect excess glue on the surface of the touch screen, and the glue inside can be cleaned by removing the second collection box 24 from the inside of the fixed base 23.

[0027] Among them, two sets of slide blocks 29 are slidably connected to the outer surfaces of two sets of limit rods 26, two sets of racks 210 are respectively meshed with gears 27, two sets of threaded plates 211 are respectively fixedly connected to the two ends of one side surface of a clamping plate 28, two sets of locking screws 212 are respectively threaded to the inside of the two sets of threaded plates 211, and the lower ends of the two sets of locking screws 212 abut against the upper surface of the support plate 21.

[0028] Pulling a set of clamping plates 28 can drive a set of slides 29 and racks 210 to move synchronously. When the racks 210 move, they can drive gears 27 to rotate. When gears 27 rotate, they can drive another set of racks 210, slides 29 and clamping plates 28 to move. At this time, the two sets of clamping plates 28 can move closer or further away synchronously, so as to clamp touch screens of different sizes and ensure the centering of the touch screen during positioning. A 2mm thick silicone buffer pad with a hardness of 50 Shore A is pasted on the side of the two sets of clamping plates 28 near the touch screen to prevent scratching the touch screen. When the lower ends of the two sets of locking screws 212 are pressed against the upper surface of the support plate 21, the position of the two sets of clamping plates 28 can be fixed.

[0029] A cylinder 32 is installed in the middle of the upper surface of the support base 31. A connecting ring 33 is fixedly connected to the lower end of the push rod inside the cylinder 32. A connecting rod 34 is fixedly connected to the surfaces of both ends of the connecting ring 33. The two ends of the glue roller 35 are connected to the connecting rod 34 by bearings. The upper end of the glue coating plate 36 is fixedly connected to the lower surface of the connecting ring 33.

[0030] By activating the cylinder 32, the internal push rod can drive the connecting ring 33, connecting rod 34 and glue roller 35 to move vertically downwards simultaneously. When the lowest point of the outer surface of the glue roller 35 is at the same height as the touch screen surface, glue can be applied to the touch screen. The glue application plate 36 is made of silicone material and has a contact pressure of 5-10N with the touch screen. The glue application plate 36 can make the glue on the upper surface of the touch screen more even.

[0031] The glue roller 35 has a glue application hole in the side wall. One end of the upper surface of the cylinder 32 is fixedly connected to a glue storage tank 37. The inside of the glue storage tank 37 is connected to a connecting pipe 38, and one end of the connecting pipe 38 is connected to the inside of the glue roller 35 through the inside of the connecting rod 34.

[0032] The glue storage tank 37 stores the glue, and an internal solenoid valve is installed inside the tank. The solenoid valve is linked to the drive motor 16 via a PLC controller. When the sensor detects that the touch screen has moved directly below the glue roller 35, the solenoid valve opens. A pressure regulating valve is installed at the outlet of the glue storage tank 37, and the glue delivery pressure can be adjusted to 0.2-0.5MPa by turning a knob. The connection between the connecting pipe 38 and the glue roller 35 is sealed with a nitrile rubber sealing ring to prevent glue leakage. After the power is turned on, the glue inside the storage tank 37 will be delivered to the inside of the glue roller 35 through the connecting pipe 38, and then overflow outward through the glue application hole of the glue roller 35. The glue roller 35 and the connecting rod 34 are connected by a deep groove ball bearing, and a fluororubber sealing ring is installed on the outside of the bearing. The diameter of the glue application hole of the glue roller 35 is 0.5-1mm. A 500-mesh stainless steel filter screen is installed at the outlet of the storage tank 37 to prevent impurities from entering the glue application hole.

[0033] The working principle and usage process of this utility model are as follows: First, the touch screen is placed on the upper surface of the support plate 21. Then, the touch screen is clamped and fixed by two sets of clamping plates 28. Then, the two sets of locking screws 212 are rotated so that their lower ends are pressed against the upper surface of the support plate 21. At this time, the position of the two sets of clamping plates 28 can be fixed. Then, the drive motor 16 is started to drive the lead screw 17 to rotate. Then, the lead screw 17 drives the moving seat 18 and the clamping structure 2 to move towards the glue coating structure 3. When the touch screen moves to the lower end of the glue roller 35, the cylinder 32 pushes the glue roller 35 so that its outer surface is in contact with the touch screen. The glue inside the glue tank 37 flows into the glue roller 35 through the connecting pipe 38. Then, as the touch screen moves, it can drive the glue roller 35 to rotate. At this time, the glue can be applied to the surface of the touch screen. Then, the glue coating plate 36 can further apply the glue evenly.
