[0002] Existing placement stages are typically planar structures. During the dispensing or sealing process of glass substrates, the adhesive used often overflows from the edges of the glass substrate and drips onto the surface of the placement stage or inside the equipment due to its high fluidity. This affects subsequent processing and is also inconvenient to clean. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a glass substrate placement stage to solve the technical problem in the prior art where the adhesive has strong fluidity and easily drips from the edge of the glass substrate onto the placement stage.

[0004] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a glass substrate placement stage, including: a base and a negative pressure generating device.

[0005] In some embodiments, the upper surface of the pedestal is further formed with a chute, the higher side of the chute being connected to the placement surface and the lower side of the chute being connected to the collection trough.

[0006] In some embodiments, the bottom surface of the collection tank has a highest point and a lowest point, and the height of the bottom surface of the collection tank continuously decreases from the highest point to the lowest point; a guide channel is also formed on the upper surface of the pedestal, the guide channel connecting the lowest point of the collection tank and extending to the outside of the pedestal.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] To address the technical problem that adhesive with high fluidity easily drips from the edge of the glass substrate onto the placement stage, this invention provides a glass substrate placement stage capable of collecting adhesive dripping from the edge of the glass substrate.

[0018] Please see Figure 1 and Figure 2 , Figure 1 This is a top view of the glass substrate placement stage provided in this embodiment of the utility model; Figure 2 yes Figure 1 A cross-sectional view of section AA. The glass substrate placement stage includes a base 1 and a negative pressure generating device 2.

[0019] The upper surface of the pedestal 1 has a placement surface 11 and a collection groove 12 arranged around the placement surface. A negative pressure air chamber 13 is also formed inside the pedestal 1. The placement surface 11 has at least one air hole 111 that communicates with the negative pressure air chamber 13.

[0020] The negative pressure generating device 2 is connected to the negative pressure air chamber 13, which generates negative pressure at the air hole 111 to adsorb the glass substrate 9 onto the placement surface 11, thereby fixing it. In a preferred embodiment, a special clamping device can also be provided to clamp and fix the glass substrate 9.

[0021] A glass substrate 9 is placed on the placement surface 11 and fixed using negative pressure. Then, an external dispensing device applies adhesive to the upper surface of the glass substrate 9. Some adhesive may drip from the edge of the glass substrate 9 and fall into the collection tank 12. This does not contaminate the placement surface 11 or affect subsequent processing of the glass substrate 9; at the same time, the adhesive collected in the collection tank 12 facilitates centralized cleaning.

[0022] In some embodiments, a chute 14 is also formed on the upper surface of the platform 1. The higher side of the chute 14 is connected to the placement surface 11, and the lower side of the chute 14 is connected to the collection tank 12. The chute 14 allows the glass substrate placement platform to accommodate glass substrates 9 of different sizes. As long as the edge of the glass substrate 9 is directly above the chute 14, the adhesive can drip onto the chute 14 and flow into the collection tank 12.

[0023] In some embodiments, the bottom surface of the collecting tank 12 has a highest point and a lowest point, and the height of the bottom surface of the collecting tank 12 continuously decreases from the highest point to the lowest point. This allows the adhesive dripping into the collecting tank 12 to flow along the collecting tank 12 to the lowest point under the action of gravity. A guide channel 15 is also formed on the upper surface of the platform 1, which connects to the lowest point of the collecting tank 12 and extends outside the platform 1. The guide channel 15 is used to discharge the adhesive.

[0024] In some embodiments, the glass substrate placement stage further includes a collection container 3, which is disposed below the outlet of the guide channel 15 to collect the adhesive flowing out of the guide channel 15.

[0025] In some embodiments, a mounting hole communicating with a negative pressure air chamber 13 is formed on the placement surface 11 of the pedestal 1. The glass substrate placement stage also includes an adsorption plate 4, which is detachably installed at the mounting hole. The adsorption plate 4 has air holes 111. By replacing different adsorption plates 4, glass substrates 9 of different sizes, thicknesses, and weights can be adapted to achieve better adsorption and fixation.

[0026] Based on the above embodiments, the pores 111 are evenly distributed on the adsorption plate 4.

[0027] In some embodiments, the negative pressure chamber 13 has an air outlet located on the side of the base 1, and the negative pressure generating device 2 is a fan disposed in the negative pressure chamber 13. The fan blows air toward the air outlet, driving the airflow to be drawn in from the air hole 111 and discharged from the air outlet, thereby generating negative pressure at the air hole 111 and sucking in the glass substrate 9.

[0028] In some embodiments, the glass substrate placement stage further includes a constant-temperature heating device 5, which is disposed below the collection tank 12 and the chute 14 to heat the collection tank 12 and the chute 14 to prevent the adhesive from solidifying. It is readily understood that whether to provide the constant-temperature heating device 5, whether to use the constant-temperature heating device 5, and at what temperature to set the constant-temperature heating device 5, are all determined based on the adhesive. The function of the constant-temperature heating device 5 is to maintain the fluidity of the adhesive, allowing it to flow smoothly into the collection container 3 and preventing it from solidifying in the collection tank 12 or the chute 14.

[0029] In some embodiments, the glass substrate placement stage further includes a negative pressure pausing device 6. The negative pressure pausing device 6 includes a drive mechanism (not shown) and a baffle 61. The drive mechanism is tractively connected to the baffle 61 and can drive the baffle 61 to move into the negative pressure chamber 13 to block the negative pressure generating device 2 and the air hole 111, thereby reducing or even eliminating the negative pressure at the air hole 111. It is easy to understand that the negative pressure pausing device 6 does not need to completely eliminate the negative pressure at the air hole 111; it only needs to reduce the negative pressure at the air hole 111 to a level that makes it easy to remove the glass substrate 9.

[0030] In some embodiments, the baffle 61 is a circular plate with a solid portion and a hollow portion. The driving mechanism is a motor, which can drive the baffle 61 to rotate, so that the solid portion and the hollow portion alternately enter the negative pressure air chamber 13, causing the negative pressure at the air hole 111 to be generated and disappear periodically. When the solid portion enters the negative pressure air chamber 13, it blocks the negative pressure air chamber 13, and the negative pressure at the air hole 111 decreases. When the hollow portion enters the negative pressure air chamber 13, the negative pressure air chamber 13 is connected, and the negative pressure at the air hole 111 is restored.

[0031] In other embodiments, other structural forms may also be adopted, such as a telescopic drive component like a cylinder, which drives the baffle 61 to make linear reciprocating motion. By manually controlling the telescopic drive component, the negative pressure at the air hole 111 can be controlled to achieve the adsorption and release of the glass substrate 9.

[0032] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
