Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment, specifically an etching box for rapid switching between multiple glass sizes. Background Technology

[0002] Glass etching, a key process in the manufacturing of precision optical components such as display panels and semiconductor devices, requires the use of chemical solutions to etch glass surfaces to meet specific precision requirements. With the diversification of end products, the sizes and specifications of glass substrates are becoming increasingly diverse (such as different models of mobile phone screens and flat panel glass). To improve equipment utilization and production flexibility, a single etching machine must have the ability to quickly switch between multiple sizes of glass substrates.

[0003] Currently, the existing technology for etching multi-size glass involves using adjustable-width etching equipment. This type of equipment typically adjusts the lateral width of the processing area by moving side guide posts to accommodate the loading and transport requirements of different glass sizes. However, to reduce chemical consumption and ensure etching uniformity, the immersion tank of the etching chamber is generally designed as a low-positioned fixed structure, located at the bottom of the chamber, making it difficult to adjust. When it is necessary to expand or reduce the processing width by moving the side guide post bases, the movement path of the side guide post bases is prone to mechanical interference with the fixed structures integrated above the immersion tank, such as guide wheels, guide wheel rods, spray oscillation devices, and side baffles. Tools and hands are difficult to insert, especially since the etching solution is corrosive; prolonged operation can also cause harm to the human body.

[0004] The method of disassembling one by one is cumbersome and time-consuming, with a single adjustment usually taking more than 12 hours, resulting in long-term equipment downtime and seriously affecting production cycle and equipment utilization. At the same time, frequent disassembly and reassembly increase labor costs and maintenance complexity, further driving up production costs. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: an etching box for rapid switching of multi-size glass, including a box body 1, a nozzle structure 2 and a guide wheel structure 3, wherein the nozzle structure 2 is disposed at the upper end of the box body 1 and the guide wheel structure 3 is disposed below the nozzle structure 2. The guide wheel structure 2 is provided with a side guide wheel structure 4 below it; The nozzle structure 2 includes multiple branch pipes 21 arranged in parallel side by side, and multiple nozzles 22 are provided below the branch pipes 21. The guide wheel structure 3 includes multiple guide wheel shafts 31 arranged in parallel side by side, and guide wheels 32 are provided on the guide wheel shafts 31. The side guide wheel structure 4 includes two symmetrically arranged sets. The side guide wheel structure 4 includes a guide wheel seat 41 and a side guide wheel 42. The guide wheel seat 41 is arranged perpendicularly to the guide wheel shaft 31. The side guide wheel 42 is arranged vertically on the guide wheel seat 41. Sliding structures 43 are provided on both sides of the guide wheel seat 41. The sliding structure 43 is connected to the side plate of the housing 1 and can assist the guide wheel seat 41 in sliding to adjust the distance between the guide wheel seats 41.

[0023] The chamber 1 is the main body for containing the etching reaction; the nozzle structure 2 is located at the top of the chamber and is responsible for spraying the etching solution; the guide wheel structure 3 is located below the nozzle structure and is responsible for glass transmission and guidance; the side guide wheel structure 4 is located below the guide wheel structure 3, with two sets arranged symmetrically, for limiting the side of the glass and adapting the width.

[0024] The nozzle structure 2 provides etching solution spraying to achieve chemical corrosion of the glass surface.

[0025] The guide wheel structure 3 drives the glass forward by rotating the guide wheel, while simultaneously constraining the longitudinal position of the glass.

[0026] The side guide wheel structure 4 constrains the lateral position of the glass by means of adjustable spacing side guide wheels, adapting to glass of different widths and avoiding interference with traditional fixed structures.

[0027] In this embodiment, the box 1 is connected to the side of the conveying structure of the previous process and has a feed inlet. The height of the feed inlet is 2mm-3mm higher than the highest point of the guide wheel 32.

[0028] The chamber 1 serves as the main container for the etching reaction; the inlet prevents the glass from colliding with the guide wheel 32 when it enters the chamber, while ensuring that the glass transport path is precisely aligned with the contact platform of the guide wheel 32.

[0029] In this embodiment, the nozzle structure 2 further includes a main pipe 23, which is connected to the outside via a tee connector.

[0030] The design features 21 parallel channels with multiple branch pipes, which, together with 22 nozzles, ensures uniform distribution of the etching solution across the cross-section of the chamber, guaranteeing consistent etching performance for glass of different sizes.

[0031] The main pipe 23 is connected to the outside via a tee joint, which simplifies the layout of the liquid supply pipeline and reduces the trouble of disassembling pipelines due to structural adjustments of traditional multi-size equipment.

[0032] In this embodiment, the guide wheel 32 is provided with a protruding contact platform, which drives the glass to move through friction. The guide wheel seat 41 is provided with a clearance groove, which is used to avoid the guide wheel 32.

[0033] The contact platform of the guide wheel 32 increases the friction with the glass, guiding and driving the glass to move along the transmission direction.

[0034] The clearance groove of the guide wheel seat 41 ensures that there is no spatial interference between the side guide wheel structure 4 and the guide wheel 32 when the side guide wheel structure 4 is adjusted.

[0035] In this embodiment, the side guide wheel 42 includes a support ring and a guide wheel ring. The support ring is located below the guide wheel ring, and the side guide wheel 42 is mounted on the guide wheel seat 41 by bolts.

[0036] The guide wheel seat 41 slides along the side wall of the box through the sliding structure 43, adjusting the distance between the two sets of guide wheel seats to accommodate glass of different widths.

[0037] The support ring and guide ring structure of the side guide wheel 42 not only conforms to the side of the glass to provide guidance, but also prevents the glass edge from directly colliding with the cabinet.

[0038] In this embodiment, the sliding structure 43 includes a sliding rail 431, a sliding table 432, and a connecting rod 433. The sliding rail 431 is installed on the outer side wall of the housing 1. The sliding table 432 is slidably connected to the sliding rail 431. One end of the connecting rod 433 is connected to the sliding table 432, and the other end is connected to the guide wheel seat 41.

[0039] The lower end of the sliding table 432 is provided with a fastening screw 434. When the fastening screw 434 is tightened, the guide wheel seat 41 is fixed by the friction between the screw and the sliding rail 431.

[0040] It includes a sliding rail 431, a sliding table 432, and a connecting rod 433; the sliding rail is installed on the outer side wall of the box, the sliding table is slidably connected to the sliding rail, one end of the connecting rod is connected to the sliding table, and the other end is connected to the guide wheel seat 41; a fastening screw 434 is provided at the lower end of the sliding table, and the guide wheel seat 43 is fixed by friction when fastened.

[0041] The guide rail pair design of the sliding rail 431 and the sliding table 432 ensures that the adjustment process of the guide wheel seat 41 is smooth and without jamming.

[0042] The fastening screw 434 fixes the position of the sliding table by friction, and quickly locks it in place after adjustment.

[0043] Furthermore, the connecting rod 433 is located above the side wall of the housing 1, so that the adjustment of the guide seat 41 does not need to go deeper into the bottom of the housing 1, thus avoiding the influence of the structure and the damage of the etching solution, and the adjustment of the guide seat 41 can be achieved from the outside.

[0044] Working principle: 1. The previous process conveying structure feeds the glass into the box from the feed port. The bottom surface of the glass contacts the contact table of the guide wheel 32. The guide wheel 32 rotates and drives the glass to move forward longitudinally.

[0045] 2. According to the width of the glass, the sliding table of the manual sliding structure 43 moves along the sliding rail, adjusts the distance between the two sets of guide wheel seats 41, so that the side guide wheel 42 fits against the side of the glass, and locks the position by fastening screw 434.

[0046] 3. The main pipe 23 of the nozzle structure 2 is filled with etching solution, which is sprayed onto the glass surface through the nozzle 22 via the branch pipe 21 and reacts chemically with the glass. Under the joint constraint of the guide wheel 32 and the side guide wheel 42, the glass passes through the etching area at a uniform speed to complete the surface etching.

[0047] Based on the above, the side guide wheel structure of this solution is independently adjustable through a sliding structure, without mechanical interference with the nozzle structure or guide wheel structure. The guide wheel seat clearance groove avoids the guide wheel, and the sliding rail is set on the outer facade of the side wall of the housing, without occupying the internal core area.

[0048] The sliding table of the sliding structure can be pushed manually directly. After adjustment, tighten the fastening screws without disassembling any fixing bolts or pipes.

[0049] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
