[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-7 This utility model provides a technical solution: a gluing and curing mechanism, including a frame 10. A conveyor belt 20 for conveying a glass substrate is provided at the center of the top of the frame 10. The width of the glass substrate is greater than the width of the conveyor belt 20. Two symmetrical gluing components 30 are provided on both sides of the conveyor belt 20 at the top of the frame 10. The gluing components 30 are used to apply glue to both sides of the glass substrate. The two gluing components 30 can move along the X-axis direction on the frame 10, thereby adjusting the distance between the two gluing components 30. The distance between the two gluing components 30 when they move to the farthest position in the X-axis direction is greater than the width of the glass substrate, ensuring that the gluing components 30 on both sides can apply glue to both sides of the glass substrate.

[0025] Specifically, the glass substrate is conveyed by the conveyor belt 20. After the glass substrate is transported between the two adhesive application components 30, the position of the glass substrate is fixed by the heating plate 38. Then, the adhesive application components 30 apply adhesive to both sides of the glass substrate and cure it. The adhesive is applied and cured at the same time, and the adhesive can quickly penetrate into the gaps on the side of the glass, ensuring the depth of adhesive penetration into the gaps on the side of the glass, ensuring uniform adhesive application, improving production efficiency and product qualification rate.

[0026] The adhesive application assembly 30 includes a base plate 31 slidably mounted on the top of the frame 10. A first X-axis electric slide rail 32 is provided on one side of the top of the frame 10 near the base plate 31. A first electric slide block 33 that cooperates with the first X-axis electric slide rail 32 is provided on the lower surface of one end of the base plate 31. The base plate 31 is slidably mounted on the top of the frame 10 through the cooperation of the first electric slide block 33 and the first X-axis electric slide rail 32. A first track 34 is provided on one side of the top of the frame 10 near the other end of the base plate 31. A first slider 35 that cooperates with the first track 34 is provided on the lower surface of the other end of the base plate 31.

[0027] The base plate 31 is slidably mounted on the frame 10 by the first slider 35 cooperating with the first track 34. The base plate 31 can be driven to slide in the X-axis direction by the first X-axis electric slide rail 32 cooperating with the first electric slide block 33, thereby adjusting the position of the glue application component 30 in the X-axis direction.

[0028] After the glass substrate is positioned on the conveyor belt 20, the base plate 31 is driven to slide in the X-axis direction by the cooperation of the first X-axis electric slide rail 32 and the first electric slide block 33, so that the adhesive application assembly 30 is close to the side of the glass substrate, thereby applying adhesive to the side of the glass substrate.

[0029] The base plate 31 has a Y-axis electric slide rail 40 on its upper surface. A support plate 41 is slidably mounted on the Y-axis electric slide rail 40. A first cylinder 42 is mounted on the support plate 41. An mounting plate is slidably mounted on the first cylinder 42. The Y-axis electric slide rail 40 can drive the support plate 41 to move in the Y-axis direction, and the first cylinder 42 can drive the mounting plate to move in the X-axis direction.

[0030] The mounting plate has a first Z-axis electric slide rail 43 on one side, and a dispensing valve 44 is slidably mounted on the first Z-axis electric slide rail 43. The dispensing valve 44 has a dispensing needle 45 at its output end. The first Z-axis electric slide rail 43 can drive the dispensing valve 44 to move in the opposite direction of the Z-axis. The input end of the dispensing valve 44 is connected to a UV glue pump through a pipe. The UV glue pump delivers UV glue to the dispensing valve 44. The dispensing valve 44 controls the glue flow rate and the dispensing needle 45 coats the UV glue onto the side of the glass substrate.

[0031] The mounting plate has a second cylinder 47 at its bottom side, and an L-shaped support frame 46 is slidably mounted on the second cylinder 47. A side wheel 48 that mates with the side of the glass substrate is rotatably mounted on the lower surface of one side of the L-shaped support frame 46. Two pressure rollers 49 are rotatably mounted on the other side of the L-shaped support frame 46. After the glass substrate is positioned on the conveyor belt 20, the base plate 31 is driven to move closer to the glass substrate by the cooperation of the first X-axis electric slide rail 32 and the first electric slide block 33, so that the glue application assembly 30 is close to the glass substrate. Then, the first cylinder 42 drives the dispensing valve 44, the side wheel 48 and the pressure roller 49 to move closer to the side of the glass substrate. At the same time, the second cylinder 42 drives the side wheel 48 and the pressure roller 49 to move downward, so that the side wheel 48 mates with the side of the glass substrate. To prevent deviation of the glass substrate, the pressure roller 49 is pressed down to press against the upper edge of the side of the glass substrate, preventing the glass substrate from arching when heated. At the same time, the dispensing valve 44 and dispensing needle 45 are driven downward by the first Z-axis electric slide rail 43 to ensure that the port of the dispensing needle 45 is aligned with the center of the side of the glass substrate, ensuring that the dispensing needle 45 can accurately apply UV glue to the center of the side of the glass substrate. Then, all the structures on the support plate 41 are driven to move along the Y-axis direction by the Y-axis electric slide rail 40 (the glass substrate is a regular directional plate), thereby driving the side roller 48 to roll forward along the side of the glass substrate, the pressure roller 49 to roll forward along the upper edge of the side of the glass substrate, and the dispensing needle 45 to apply UV glue forward along the center of the side of the glass substrate.

[0032] The mounting plate has a connecting plate 50 at the tail end, and a UV LED curing lamp 51 at the end of the connecting plate 50. As the support plate 41 moves forward along the Y-axis, the UV LED curing lamp 51 moves synchronously. At the same time, the UV LED curing lamp 51 cures the UV adhesive coated at the center of the side of the glass substrate, achieving edge coating and variable curing.

[0033] The mounting plate has a vertical plate 52 at the bottom and a waste glue collection box 53 on the front of the vertical plate 52. The waste glue collection box 53 is located directly below the glue dispensing needle 45. During the glue application process, the dripping UV glue will fall into the waste glue collection box 53 for collection.

[0034] The base plate 31 has a side plate 36 on its inner side, and a first sliding cylinder 37 on its side. The output end of the first sliding cylinder 37 has a heating plate 38 for heating the side of the glass substrate. The heating plate 38 has a vacuum chamber inside, and vacuum adsorption holes communicating with the vacuum chamber are evenly distributed on its surface. The vacuum chamber is connected to an external vacuum pump via a flexible hose. Specifically, the glass substrate is conveyed by a conveyor belt 20. After the glass substrate is transported between the two coating components 30, the first sliding cylinder 37 pushes the heating plate 38 upward, causing it to approach (and contact) the lower edge of the side of the glass substrate. Then, the external vacuum pump is turned on to extract air from the vacuum chamber and heat the glass substrate. A negative pressure suction is formed on the surface of the heating plate 38, and the glass substrate is then adsorbed and fixed on the heating plate 38 through the vacuum adsorption holes on the surface of the heating plate 38. At the same time, the heating plate 38 heats the edge of the glass substrate. Then, the first X-axis electric slide rail 32 and the first electric slide block 33 cooperate to drive the base plate 31 to move closer to the glass substrate, so that the adhesive application component 30 is close to the glass substrate. The adhesive application component 30 applies coating to the side of the glass substrate, and the heating plate 38 heats the edge of the glass substrate, quickly penetrating the adhesive into the gap on the side of the glass substrate to ensure the depth of adhesive penetration into the gap on the side of the glass substrate. The heating plate 38 is equipped with heating wires, which generate heat to heat the edge of the glass substrate.

[0035] Working principle: In use, the glass substrate is conveyed by the conveyor belt 20. After the glass substrate is delivered between the two coating components 30, the heating plate 38 is pushed upward by the first slide cylinder 37, so that the heating plate 38 approaches (and contacts) the lower edge of the side of the glass substrate. Then, the external vacuum pump is turned on, and the air in the vacuum chamber is extracted by the vacuum pump, forming a negative pressure suction on the surface of the heating plate 38. Then, the glass substrate is adsorbed and fixed on the heating plate 38 through the vacuum adsorption holes on the surface of the heating plate 38. At the same time, the heating plate 38 heats the edge of the glass substrate. Then, the first X-axis electric slide rail 32 and the first electric slide block 33 cooperate to drive the base plate 31 to move closer to the side of the glass substrate, so that the coating component 30 is close to the glass substrate. Then, the first cylinder 42 drives the dispensing valve 44, the side wheel 48 and the pressure roller 49 to move closer to the side of the glass substrate. The second cylinder 42 drives the side wheel 48 and pressure roller 49 to move downwards, bringing the side wheel 48 into contact with the side of the glass substrate to prevent deviation. The pressure roller 49 is pressed down to press against the upper edge of the side of the glass substrate to prevent it from arching when heated. At the same time, the first Z-axis electric slide rail 43 drives the dispensing valve 44 and dispensing needle 45 to move downwards, ensuring that the port of the dispensing needle 45 is aligned with the center of the side of the glass substrate. This ensures that the dispensing needle 45 can accurately apply UV glue to the center of the side of the glass substrate. Then, the Y-axis electric slide rail 40 drives all the structures on the support plate 41 to move along the Y-axis (the glass substrate is a regular directional plate), thereby causing the side wheel 48 to roll forward along the side of the glass substrate, the pressure roller 49 to roll forward along the upper edge of the side of the glass substrate, and the dispensing needle 45 to apply UV glue forward along the center of the side of the glass substrate.
