Description

Technical Field

[0001] The present invention relates to the field of glass substrate packaging, and in particular to a glass substrate pressing device suitable for UV glue packaging. Background Art

[0002] In the packaging process of the panel industry, in order to effectively block water and oxygen from the product, UV glue is used to seal the product frame. That is, the UV glue is sprayed on the glass cover in a set pattern or track, and then pressed with the circuit substrate for curing. UV glue must be irradiated by a UV lamp before it can be cured. Currently, there are two main types of UV glue: instant curing and delayed curing. Instant curing means that the glue material is completely cured during the UV lamp irradiation process, and delayed curing means that curing begins after a short period of time after the UV lamp irradiation. Different UV glues are used, and the corresponding pressing equipment cannot be universal. Summary of the Invention

[0021] like Figure 1-4 As shown, the present invention is a glass substrate pressing device suitable for UV glue packaging, which includes a base 1, a stage 2, an upper base module 3 and a lower base module 4;

[0022] A UV LED lamp 5 is fixed to the upper end surface of the base 1 , and the light-emitting surface of the UV LED lamp 5 is arranged upward.

[0023] The loading platform 2 is mounted directly above the UV LED lamp 5. It is equipped with a trough 21, with two adjacent sides of the trough 21 each equipped with a positioning block 22 (the positioning block 22 is molded from rubber and provides a cushioning effect to prevent damage to the glass cover). Each positioning block 22 is driven by a telescopic actuator. The loading platform 2 receives the circuit board and glass cover from the robot and calibrates their positions. During the pressing process, the loading platform 2 supports the glass cover on all sides. In the center of the loading platform is a stepped trough 21. To facilitate smooth transfer of the glass cover into the trough 21 by the robot, the trough 21 is designed to be slightly wider than the size of the glass cover. With one long side and one short side of the trough 21 serving as reference edges, a positioning block 22 is installed on each of the opposite sides. Once the glass cover is transferred to the trough 21 by the robot, the telescopic actuator extends the positioning block 22, pushing the glass cover toward the reference edge to achieve alignment.

[0024] The upper base module 3 includes a lifting drive mechanism 31 and an upper base 32. The upper base 32 is located just above the stage 2 and is driven by the lifting drive mechanism 31 to perform lifting movements. A plurality of tracheal branches 33 are movably connected to the upper base 32. The tops of the tracheal branches 33 converge and are connected to a main air pipe 34. The main air pipe 34 is connected to a tracheal hose 36. The tracheal hose 36 is connected to a vacuum pumping device. The bottoms of the respective tracheal branches 33 are fixedly connected to vacuum suction cups 37. A retaining ring 38 is fixed on the rod body of the vacuum suction cup 37. The retaining ring 38 is located in the cavity inside the upper base 32. A spring 39 is provided between the retaining ring 38 and the top wall of the cavity of the upper base 32. The vacuum suction cup 37 is in a natural state. The lower portion is straightened to the maximum extent and extends out of the bottom surface of the upper base 32. In this embodiment, there are 8 vacuum suction cups 37, and the rod lengths of the vacuum suction cups 37 are not exactly the same. When the vacuum suction cups 37 are pulled to the maximum, the rod body of the middle vacuum suction cup 37 is longer, and the rod length gradually decreases toward both sides, so that the circuit substrate presents a small arc with the middle lower and the two sides higher. In order to prevent a large error in the relative position with the glass substrate due to excessive arc, the length difference between the longest rod and the shortest rod is 2-3mm; during the pressing process, the middle position of the circuit substrate first contacts and fits with the glass cover plate, and then the two sides slowly descend until the vacuum suction cups 37 are pressed into the groove body 21, and the circuit substrate and the glass cover plate are completely fitted together. In this way, the gas between the circuit substrate and the glass cover plate can be fully discharged, and the pressing is more complete.

[0025] The lower base module 4 is arranged between the UV LED lamp 5 and the worktable 2. The lower base module 4 includes a horizontal transverse driving mechanism 41, a transverse slide 42, a lifting driver 43 and a support plate 44. The transverse slide 42 is connected to the horizontal transverse driving mechanism 41 and is driven by the horizontal transverse driving mechanism 41 to perform transverse movement. The lifting driver 43 is fixed on the transverse slide 42. The support plate 44 is fixed on the push rod end of the lifting driver 43, and the lifting driver 43 drives the support plate 44 to perform lifting movement. The function of the lower base module 4 is to support the glass cover during the pressing process and to move away after the first pressing stage is completed so that the UVLED lamp 5 does not block the irradiation of the glass cover. When the pressing action is required, the support plate 44 moves to the right below the stage 2, and the lifting drive 43 extends to align the support plate 44 with the bottom surface of the groove body 21 of the stage 2, and jointly support the glass cover during the pressing action. After the first pressing stage is completed, the lifting drive 43 retracts with the support plate 44, and after retracting into place, the horizontal traverse drive mechanism 41 will support Plate 44 moves to the other side; due to the withdrawal of the support plate 44, the pressed glass composite plate will produce a downward deformation under the action of gravity, and the circuit substrate and the glass cover plate have different deformation amounts. A slight deformation difference may increase the gap between the circuit substrate and the glass cover plate and affect the pressing effect. At this time, the vacuum suction cup 37 applies a downward force to the circuit substrate and the glass cover plate under the elastic force of the spring 39, and reduces the deformation difference between the circuit substrate and the glass cover plate by increasing the deformation amount of the circuit substrate and the glass cover plate, thereby achieving the purpose of reducing the gap between the circuit substrate and the glass cover plate.

[0026] In the present invention, the telescopic actuator is a telescopic cylinder. The lifting actuator 43 is a lifting cylinder. The lifting drive mechanism 31 and the horizontal traverse drive mechanism 41 are screw-nut pairs driven by servo motors.

[0027] The workflow for instant-curing UV glue packaging is as follows: first, the circuit substrate is roughly aligned by the robot and then transferred to the slot 21 of the stage 2 with the front side facing down (the circuit and organic material are on the front side). The alignment top block 22 pushes the circuit substrate toward the reference edge. The upper base module 3 slowly descends under the drive of the lifting drive mechanism 31. The vacuum suction cup 37 in the middle of the upper base module 3 first contacts the circuit substrate. The upper base module 3 continues to slowly descend until all the vacuum suction cups 37 are in contact with the circuit substrate. The suction of the vacuum suction cup 37 is turned on, the alignment top block 22 contracts, and the upper base module 3 begins to rise and during the rising process Due to the elastic force of the spring 39 and the gravity of the circuit substrate itself, the vacuum suction cup 37 is stretched to the maximum extent, and the circuit substrate presents a slight curvature with a low center and high sides; after the glass cover is roughly aligned by the robot, it is transferred into the groove body 21 of the loading platform 2 with the front side facing up, and the alignment top block 22 is also extended to make it fit with the reference edge to achieve the effect of precise alignment; then the lower base module 4 starts to operate to move the support plate 44 to align with the groove body 21, supporting the glass cover, the alignment top block 22 shrinks, and the upper base module 3 descends to enter the pressing stage. The first stage of pressing is to fully press the substrate and the cover. After the end, the lower base module 4 is moved away, the UV LED lamp 5 is turned on, and the glass plywood begins to cure after receiving the UV light; after the curing is completed, the upper base module 3 rises, and the glass plywood can be directly taken away by the robot. The whole process can be controlled by program signals without manual operation.

[0028] If delayed-curing UV glue is used for packaging, the difference between the packaging process and the instant-curing UV glue is as follows: After the circuit substrate and the glass cover are both transferred into the device using the instant-curing UV glue packaging operation mode, they are first irradiated with UVLED before pressing to make the UV glue react and cure, and then pressing begins. The lower base is evacuated after the curing is completed. The entire process can also be automatically operated.

The above-mentioned specific implementation methods are illustrative rather than limiting the present invention.
