Description

Technical Field

[0001] This utility model relates to the field of glass substrate equipment technology, and in particular to a sealing buffer device for the side cover of the baking unit of a developing machine. Background Technology

[0002] When the substrate is being placed or removed from the baking unit of the coating and developing machine, the Shutter action is used to control the opening and closing or isolation between the high-temperature chamber and the outside world. The baking process needs to maintain temperature uniformity and good particle quality, so the sealing requirements are high. Therefore, the buffer device integrated assembly of the side cover of the high-temperature chamber needs to have good sealing performance.

[0003] The existing high-temperature cavity side cover sealing ring is composed of 6 spliced ​​segments. These splices are prone to breakage under high-temperature conditions, leading to poor cavity sealing, particle generation, and poor product quality. Repeated reinforcement at the splices fails to achieve long-term sealing. For example... Figure 1 The existing sealing ring cross-section shown consists of a flat fixing plate and an arc-shaped buffer surface. The fixing plate of the sealing ring is fixed to the edge of the side plate at the equipment end by stainless steel pressure strips and screws. When the shutter is closed, the buffer surface is prone to deformation, resulting in poor sealing.

[0004] Therefore, there is an urgent need for a sealing and buffering device for the side cover of the baking unit of a developing machine that is simple in structure, easy to install, and not easily deformed or broken. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a sealing and buffering device for the side cover of the baking unit of a developing machine that is simple in structure, easy to install, and not easily deformed or broken.

[0007] A sealing ring, an integrally molded annular structure, with a cross-section resembling an "Ω" shape, one end of which has an inwardly protruding snap-fit ​​protrusion, and the other end has a T-shaped end with an inverted "T" structure;

[0008] A fixing component comprises a rectangular structure consisting of two long-side fixing members and two short-side fixing members. Each of the long-side and short-side fixing members consists of a base and a pressure strip. The base consists of an integrally formed horizontal plate and a fixing plate. The fixing plate is disposed on one side of the horizontal plate, and a first pressure tongue protrudes outward from one side of the fixing plate. The horizontal plate has several internal through holes along its length, and the fixing plate has several external through holes along its length. A snap-fit ​​recess is provided on the outer side of the fixing plate, which engages with the snap-fit ​​protrusion of the sealing ring. The pressure strip is disposed on the horizontal plate and fixed by bolts passing through the pressure strip and the internal through holes. A second pressure tongue protrudes outward from one side of the pressure strip, and the second pressure tongue and the first pressure tongue are disposed opposite each other and form an inverted T-shaped groove between the second and the first pressure tongue and the horizontal plate. The T-shaped end of the sealing ring is engaged in the inverted T-shaped groove.

[0009] Furthermore, the long side fastener has a plug-in end extending outward from both ends of the pressure strip, and the short side fastener has a notch at both ends of the base, with the plug-in end inserted below the first pressure tongue at the notch at both ends of the base of the short side fastener.

[0010] Furthermore, the outer sides of both ends of the base of the short-side fixing member have an arc-shaped chamfered structure.

[0011] Furthermore, the long-side fastener is formed by splicing together a multi-segment structure.

[0012] The advantages of this utility model are as follows: the one-piece molded sealing ring can prevent breakage when the shutter opening is closed; by setting the sealing ring into an "Ω"-shaped structure, with both ends fixed by fixing components, the sealing performance is enhanced and it is not easily deformed; the fixing components can be used to fasten the sealing ring to the equipment end; this utility model provides a simple structure, easy installation, and non-deformable and non-breakable sealing buffer device for the side cover of the baking unit of a developing machine.
