AI Technical Summary
Traditional single-sided display panel devices bear a heavy load during the glass substrate flattening process, making it difficult to flatten stably. This results in uneven glass substrates on the conveyor belt, making them fragile and causing thermal stress due to temperature changes, which poses a safety hazard.
A bidirectional flattening device is used, in which the plate is connected by the first and second cylinders to flatten it in both directions. A temperature control unit controls the temperature of the glass substrate during the flattening process, and a suction cup is used to adsorb the glass substrate for uniform flattening and temperature regulation.
This method achieves uniform stress distribution on the glass substrate during the flattening process, preventing glass substrate breakage, improving the shape stability and optical performance of the glass substrate, and controlling temperature changes to ensure the flatness and safety of the glass substrate.

[0002] In the production and manufacturing process of liquid crystal substrate glass, the cut glass and the glass taken from the conveying belt need to be flattened, so as to prevent the glass from being twisted and broken.
[0003] The conventional flattening device flattens the glass through one-side flattening, and the action end of the one-side flattening has a large load. The flattening device cannot be flattened to the set position, so that the glass substrate is not flat when being hung on the conveying belt, is easily broken when being transported on the conveying belt, and the temperature of the glass substrate itself is greatly different from the temperature of the outside during the flattening process, which can cause thermal stress in the glass substrate due to the rapid temperature change during the flattening process. In a serious case, the glass can be broken during the flattening process, which can cause safety hazards. SUMMARY
[0004] To solve the technical problems in the background art, the present application provides a glass substrate bidirectional flattening device.
[0005] To achieve the above object, the present application provides the following technical scheme.

[0010] a temperature control unit, the temperature control unit being installed on a third plane of the mounting frame, the first plane, the second plane and the third plane being parallel to each other;
[0011] When the plurality of first suction cups and the plurality of second suction cups adsorb the first wall of the glass substrate, the first plate body and the second plate body move in the extension direction of the glass in the opposite direction to flatten the glass substrate, and the temperature control unit generates hot gas to keep the temperature of the glass substrate constant during the flattening process. After the flattening is completed, the temperature control unit generates cold gas to cool the glass substrate.
[0012] Preferably, the temperature control unit further comprises a third plate body connected with the third plane of the mounting frame, and the temperature control unit is arranged in the third plate body; and a plurality of air jet ports coplanar with and parallel to the third plane.

[0014] Preferably, the temperature control unit further comprises a third plate body connected with the third plane of the mounting frame, and the temperature control unit is arranged in the third plate body; and a plurality of air jet ports coplanar with and parallel to the third plane.
[0015] Preferably, the first and second plate bodies have a rectangular cross section of 40mm*40mm in the extension direction thereof.
[0016] Compared with the prior art, the present application has the following advantages:
[0017] Compared with the prior art, the glass substrate can be more evenly stressed in the extension direction of the first wall during the two-way flattening process, thereby avoiding excessive stress concentration and increasing the risk of glass substrate breakage.

DETAILED DESCRIPTION
[0022] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0023] As shown in the drawings, Figs. 1-3 The present embodiment provides a glass substrate bidirectional flattening device, comprising:
[0024] a mounting frame 1;
[0025] a first cylinder 3, the first cylinder 3 is installed on the mounting frame 1, the first cylinder 3 is connected with a first plate body 4, the first plate body 4 is provided with a plurality of first suction cups 41 on a first plane 42 in the extension direction of the first plate body 4;
[0026] a second cylinder 5, the second cylinder 5 is installed on the mounting frame 1 and located on the opposite side of the first cylinder 3, the second cylinder 5 is connected with a second plate body 6, the second plate body 6 is provided with a plurality of second suction cups 61 on a second plane 62 in the extension direction of the second plate body 6, the extension direction of the second plate body 6 is consistent with the extension direction of the first plate body 4;
[0027] a temperature control unit 2, the temperature control unit 2 is installed on a third plane 23 of the mounting frame 1, the first plane 42, the second plane 62 and the third plane 23 are parallel to each other;
[0028] When the plurality of first suction cups 41 and the plurality of second suction cups 61 adsorb the first wall 71 of the glass substrate 7, the first plate body 4 and the second plate body 6 move away along the extension direction of the glass to realize the flattening of the glass substrate 7, and the temperature control unit 2 generates hot gas to keep the temperature of the glass substrate 7 constant during the flattening process. After the flattening is completed, the temperature control unit 2 generates cold gas to realize the cooling treatment of the glass substrate 7.
[0029] Overall, the first wall 71 of the glass substrate 7 is adsorbed by the first suction cup 41 and the second suction cup 61, after the adsorption of the first wall 71 is completed, the first cylinder 3 and the second cylinder 5 are driven to move away along the extension direction of the glass substrate 7 to flatten the glass substrate 7, and in the process of flattening the glass substrate 7, the temperature control unit 2 generates high-temperature gas to keep the temperature of the glass substrate 7 constant during the flattening process. After the flattening of the glass substrate 7 is completed, the temperature control unit 2 generates low-temperature gas and performs cooling treatment on the flattened glass substrate 7.
[0030] When the glass substrate 7 is flattened and cooled, the glass substrate 7 is placed on the conveying belt by the mechanical arm, and the first suction cup 41 and the second suction cup 61 are separated from the glass substrate 7, and then the glass substrate 7 is conveyed by the conveying belt.
[0031] Compared with the prior art, the glass substrate 7 can be more uniformly stressed in the extension direction of the first wall 71 during the two-way flattening process, thereby avoiding excessive stress concentration and increasing the risk of glass substrate 7 breakage. Compared with one-way flattening, two-way flattening can not only improve the shape stability of the glass substrate 7, but also optimize the optical performance of the glass substrate 7. By providing the temperature control unit 2, the temperature of the glass substrate 7 during flattening can be better controlled, thereby avoiding excessive temperature changes that cause thermal stress inside the glass substrate 7, ensuring the stability of the glass substrate 7 during flattening to improve the flatness of the glass, and further improving the optical performance of the glass substrate 7 during flattening.
[0032] As shown in Fig. 1 and Fig. 3 In one embodiment, the temperature control unit 2 further includes a third plate body 22 and a plurality of air injection ports 21. The third plate body 22 is connected to the third plane 23 of the mounting frame 1, and the temperature control unit 2 is disposed in the third plate body 22. The plurality of air injection ports 21 are coplanar and parallel to the third plane 23.
[0033] Specifically, the temperature control unit 2 includes a heating unit and a refrigeration unit. Both the heating unit and the refrigeration unit are disposed in the third plate body 22. After the first suction cup 41 and the second suction cup 61 complete the adsorption of the glass substrate 7, the first cylinder 3 and the second cylinder 5 are driven to move the first plate body 4 and the second plate body 6 away from the glass substrate 7 in the extension direction of the glass substrate 7 to flatten the glass substrate 7. During the flattening process of the glass substrate 7, hot gas generated by the heating unit is injected from the plurality of air injection ports 21 to maintain the temperature of the glass substrate 7 stable during the flattening process. After the glass substrate 7 is flattened, the cold gas generated by the refrigeration unit can cool the glass substrate 7, thereby eliminating the stress generated inside the glass substrate 7 during the flattening process and stabilizing the glass quickly.
[0034] As shown in Fig. 3 In one embodiment, when the glass substrate 7 is flattened, the contact surface of the glass substrate 7 with the first suction cup 41 and the second suction cup 61 is parallel to the coplanar plane formed by the air injection port.
[0035] Specifically, when the glass substrate 7 is completed flattening treatment, the common plane formed by the plurality of air jet ports 21 is parallel to the contact surface of the glass substrate 7 and the first chuck 41 and the second chuck 61, and when the glass substrate 7 is completed flattening treatment, the refrigeration unit starts to work, which can make the temperature of the glass substrate 7 uniformly reduced, effectively improve the product quality and stability of the glass substrate 7, and also effectively improve the optical performance of the glass substrate 7.
[0036] As shown in the figure, in one embodiment, a solenoid valve is further included, and the solenoid valve is electrically connected with the first cylinder 3 and the second cylinder 5. Figs. 1-2
[0037] Specifically, the solenoid valve is electrically connected with the first cylinder 3 and the second cylinder 5, and synchronous driving of the first cylinder 3 and the second cylinder 5 is realized through the solenoid valve, which can make the stress of the glass substrate 7 uniform during flattening, and avoid the breakage of the glass substrate 7 during flattening due to uneven stress.
[0038] As shown in the figure, in one embodiment, the cross-sectional size of the first plate body 4 and the second plate body 6 in the extension direction thereof is a rectangle of 40mm*40mm. Figs. 1-2
[0039] Specifically, the cross-sectional size of the first plate body 4 and the second plate body 6 in the extension direction thereof is a rectangle of 40mm*40mm, and when the first cylinder 3 and the second cylinder 5 respectively drive the first plate body 4 and the second plate body 6 to move away, the first plate body 4 and the second plate body 6 can be uniformly stressed, and compared with irregular figures, the bearing capacity and stability of the first plate body 4 and the second plate body 6 as a whole are improved, and the phenomenon of stress concentration in the local part of the first plate body 4 and the second plate body 6 is avoided.
