Description

Technical Field

[0001] This application relates to the field of coating technology, and in particular to a support device for a three-dimensional continuous line coating cavity. Background Technology

[0002] With the rapid development of TGV glass substrate technology, the mainstream glass substrate size in the market has been standardized at 510*515*0.5mm. As the thickness continues to decrease, the requirements for stability during the coating process become increasingly stringent. In the production scenario of a vertical continuous coating machine, such as... Figure 1 As shown, the distance between the support and guide rollers inside the coating cavity and the outlet of the coating cavity is usually large, which makes it easy for the carrier carrying the glass substrate to vibrate when passing through this area. This vibration is directly transmitted to the glass substrate it is carrying. During continuous movement, the thin glass substrate, due to its weak rigidity, is unable to withstand this kind of vibration and impact, and is very prone to breakage or cracking, which seriously affects product yield and production efficiency.

[0003] The existing coating cavity design lacks precise positioning and vibration reduction design at the connection between the support and transmission guide wheel and the coating cavity outlet. It cannot effectively adapt to the transportation requirements of thin glass substrates and is difficult to solve the problem of vibration transmission during the transition stage of the carrier. There is an urgent need for a solution that can optimize the support stability of thin glass substrates and reduce vibration impact. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this application provides a support device for a three-dimensional continuous coating cavity. When this support device is applied between the support and transmission guide wheel and the outlet of the coating cavity, it can solve the problem of vibration transmission during the transition phase of the carrier.

[0005] To achieve the above objectives, this application employs the following technical solution: This application provides a support device for a three-dimensional continuous line coating cavity, including... The guide wheel includes a circular wheel body with a first through hole through the center of the circular wheel body along the axis. The outer circumferential surface of the circular wheel body is recessed to form an arc-shaped groove. The two sides of the arc-shaped groove are correspondingly raised to form symmetrical annular protrusions. The outer surface of the annular protrusions is a smooth arc surface and its height is higher than the bottom of the arc-shaped groove. It is used to support and guide the carrier carrying the glass substrate. A rotating shaft passing through a first through hole in the guide wheel; A rotating shaft mounting assembly includes two symmetrically arranged rotating shaft clamps for supporting and clamping both ends of the rotating shaft; A fixing component, mechanically connected to the rotating shaft mounting assembly, is used to fix the rotating shaft mounting assembly onto the cavity of the coating equipment and to adjust the position of the guide wheel.

[0006] As a further improvement of this application, the fixing component includes a first nut assembly. The two symmetrically arranged rotating shaft clamping seats are respectively provided with first threaded holes. The first nut assembly is divided into two groups. Each group of the first nut assembly passes through the first threaded hole of the corresponding rotating shaft clamping seat and abuts against the opposite side walls of the coating equipment cavity to fix the rotating shaft mounting seat assembly to the side wall of the coating equipment cavity.

[0007] As a further improvement of this application, the two sets of the first nut assemblies are arranged symmetrically.

[0008] As a further improvement of this application, the fixing component further includes a horizontally arranged main support plate and two parallel and symmetrical side plates vertically fixed to both sides of the main support plate; the rotating shaft mounting seat assembly is fixedly installed on the main support plate, and the two side plates are respectively provided with second threaded holes.

Each group of first nut assemblies passes through the second threaded holes of the corresponding side plates and abuts against the opposite side walls of the coating equipment cavity, so as to fix the rotating shaft mounting seat assembly and the fixing component together to the side wall of the coating equipment cavity.

[0009] As a further improvement of this application, the side plate and the main support plate are integrally formed.

[0012] As a further improvement of this application, the support assembly is a second nut assembly, and the main support plate is provided with a third threaded hole. The second nut assembly passes through the third threaded hole and abuts against the bottom of the coating equipment cavity.

[0013] As a further improvement of this application, the second nut assembly includes at least two second nuts.

[0014] As a further improvement of this application, the two second nuts are distributed along the diagonal of the main support plate.

[0015] The beneficial effects of this application are as follows: This application provides a support device, including guide wheels for supporting and guiding a glass substrate carrier, a rotating shaft for the guide wheels, a rotating shaft mounting assembly with two symmetrical rotating shaft clamps, and a fixing assembly mechanically connected to the rotating shaft mounting assembly; the fixing assembly can fix the rotating shaft mounting assembly to the coating equipment cavity, while simultaneously adjusting the position of the guide wheels.

[0028] The technical solution of this application will be clearly and completely described below with reference to the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to specific embodiments.

[0030] In a specific implementation plan, such as Figure 2 As shown, this application provides a support device for a three-dimensional continuous line coating cavity 2, including a guide wheel 31, a rotating shaft 32, a rotating shaft 32 mounting base assembly, a fixing assembly, and a support assembly.

[0031] The guide wheel 31 includes a circular wheel body with a first through hole running through its center along its axis. The outer circumference of the circular wheel body is recessed in the middle to form an arc-shaped groove. Symmetrical annular protrusions are formed on both sides of the arc-shaped groove. The outer surface of each annular protrusion is a smooth arc surface and its height is higher than the bottom of the arc-shaped groove, serving to support and guide the carrier carrying the glass substrate. The rotating shaft 32 passes through the through hole of the guide wheel 31. The rotating shaft 32 mounting assembly includes two symmetrically arranged rotating shaft 32 clamping seats. The rotating shaft 32 clamping seats are generally T-shaped, with the bottom of the T-shape serving as a base. One side of the top of the T-shape has a second through hole 331 for the rotating shaft 32 to pass through, and the other side has a third through hole 332 for mounting fasteners. The rotating shaft 32 mounting assembly as a whole supports and clamps both ends of the rotating shaft 32.

[0032] The fixing assembly includes a horizontally arranged main support plate, two parallel and symmetrical side plates 34 vertically fixed to both sides of the main support plate, and a first nut assembly 35. The first nut assembly 35 consists of eight first nuts, and the side plates 34 are integrally formed with the main support plate. The rotating shaft 32 mounting base assembly is detachably fixed to the main support plate by mounting nuts. Each of the two side plates 34 has four second threaded holes. The first nut assemblies 35 are divided into two groups and arranged symmetrically, with four first nuts in each group. Each group of first nut assemblies 35 passes through the four second threaded holes of the corresponding side plate 34 and abuts against the opposite side walls of the coating equipment cavity, thereby fixing the rotating shaft 32 mounting base assembly and the fixing assembly together to the side walls of the coating equipment cavity.

[0033] The support assembly is a second nut assembly 36, which consists of four second nuts. The main support plate has four third threaded holes. The four second nuts are respectively inserted through the four third threaded holes and abut against the bottom of the coating equipment cavity. They are used to provide auxiliary support for the rotating shaft 32 mounting base assembly, the rotating shaft 32 and the guide wheel 31. The four second nuts are respectively located at the four corners of the diagonal of the main support plate.

[0034] The working principle of the support device for the three-dimensional continuous line coating cavity 2 is as follows: During assembly, the rotating shaft 32 passes through the first through hole of the guide wheel 31, and then both ends of the rotating shaft 32 pass through the second through holes 331 of the corresponding side rotating shaft 32 clamping seats. Fasteners pass through the third through holes 332 of the corresponding side rotating shaft 32 clamping seats, respectively, to lock both ends of the rotating shaft 32 onto the corresponding side rotating shaft 32 clamping seats. Then, the rotating shaft 32 mounting seat assembly is detachably fixed to the main support plate by installing nuts. The main support plate and the two integrally formed side upright plates 34 form the main body of the fixing assembly. Subsequently, the eight first nuts will be assembled... The first nut assembly 35 is divided into two groups (4 nuts in each group) and symmetrically inserted into the four second threaded holes of each of the two side upright plates 34. The extension length of each group of first nuts is adjusted so that they abut against the opposite side walls of the coating equipment cavity and lock in place, achieving stable positioning of the fixing assembly and the mounting base assembly of the rotating shaft 32. Simultaneously, the second nut assembly 36, consisting of four second nuts, is assembled one-to-one through the four third threaded holes on the main support plate, so that the four second nuts distributed diagonally abut against the bottom of the cavity, forming multi-point balanced auxiliary support for the overall structure. Figure 3 As shown, the support device of this application is located between the support and transfer guide wheel 1 and the outlet of the coating cavity 2, and its position can be adjusted according to the actual situation to ensure the smooth transport of the thin glass substrate.

[0035] During operation, the carrier carrying the glass substrate is placed on the guide wheel 31. The guide wheel 31 moves with the carrier and rotates smoothly through the rotating shaft 32. The eight first nuts are fixed at multiple points symmetrically on both sides, ensuring horizontal force balance and preventing the overall structure from shifting to the left or right. The four diagonally distributed second nuts strengthen the load-bearing stability of the main support plate from the bottom and prevent it from warping due to stress. By adjusting the extension of each group of the first nut assembly 35 and the extension of each nut of the second nut assembly 36, the up, down, left, and right positions of the guide wheel 31 can be precisely controlled, so that the carrier can achieve a seamless transition at the cavity connection, effectively reducing vibration transmission, reducing the risk of breakage and cracking of the thin glass substrate, and ensuring the stable operation of the continuous coating process.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
