Description

Technical Field

[0001] This utility model belongs to the field of glass acid etching. Specifically, this utility model relates to a structure for preventing the set frame trolley from falling back. Background Technology

[0002] To provide customers with high-quality flat panel display screens, the fine processing services for TFT optoelectronic glass thinning, surface polishing, and optical coating are showing a development trend. These products are mainly used in mobile smart terminals such as smartphones and tablets. With the development of technology, spray thinning equipment has also emerged. Because spray thinning has better quality and is more efficient than immersion thinning, spray setting rack trolleys are more widely used. However, the setting rack trolley is prone to backing up during acid etching, which affects the acid etching effect and product quality.

[0003] To address the aforementioned problems, patent document CN 216584749U discloses an acid etching and thinning device that can improve the appearance of glass, comprising an acid tank, a trolley, a setting frame, and a foaming tube. The inner wall of the acid tank is fixedly connected to a limiting groove, the bottom of the acid tank has a drain port, the inside of the acid tank is equipped with a foaming tube, a conveying pipe is provided on one side of the acid tank, the top of the trolley is fixedly connected to the bottom of a lifting structure, the bottom of the trolley is fixedly connected to a hook, and the top of the lifting structure is fixedly connected to the bottom of a crossbeam. However, this device cannot solve the aforementioned problems. Utility Model Content

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0021] Figure 1 This is a schematic diagram of the anti-reverse structure of the trolley in an embodiment of this utility model; Figure 2 This is a schematic diagram of the anti-reverse structure of the trolley in the rear view of an embodiment of this utility model; Figure 3 This is a schematic diagram of the limiting plate in an embodiment of this utility model.

[0022] like Figure 1 , Figure 2 as well as Figure 3 As shown, the anti-reverse structure of the setting rack trolley provided by this utility model is installed on the rear baffle of the setting rack trolley. The anti-reverse structure of the setting rack trolley includes a fixed plate 10 and a limiting plate 20 installed on the fixed plate 10. The limiting plate 20 is movably connected to the fixed plate 10. The limiting plate 20 can support the setting rack trolley during the acid etching process and prevent the setting rack trolley from reversing, thereby improving product quality. At the same time, the limiting plate 20 can be flipped to remove the limitation on the setting rack trolley, making it convenient for the setting rack trolley to move to the next process, thus improving the reliability of the structure.

[0023] The fixing plate 10 includes a first fixing plate 11 and a second fixing plate 12. The first fixing plate 11 and the second fixing plate 12 are respectively disposed on both sides of the limiting plate 20. The first fixing plate 11 and the second fixing plate 12 are arranged parallel to each other. The first fixing plate 11 is provided with a first mounting hole 111, and the second fixing plate 12 is provided with a second mounting hole 121. Bolts are inserted into the first mounting hole 111 and the second mounting hole 121, so that the first fixing plate 11 and the second fixing plate 12 are installed on the rear baffle of the setting frame trolley by bolts. This allows for easy disassembly and replacement, and at the same time, it can prevent the loss of the anti-backward structure of the setting frame trolley, thus improving the reliability of the structure.

[0024] The first fixing plate 11 has a first through hole 112, and the second fixing plate 12 has a second through hole 122 that matches the first through hole 112. The position of the second through hole 122 corresponds to the position of the first through hole 112. A rotating shaft 30 is inserted into the first through hole 112 and the second through hole 122. The two ends of the rotating shaft 30 are respectively set in the first through hole 112 and the second through hole 122. One end of the rotating shaft 30 is connected to the first through hole 112 by an interference fit, and the other end of the rotating shaft 30 is connected to the second through hole 122 by an interference fit, thereby fixing the rotating shaft 30 through the first fixing plate 11 and the second fixing plate 12.

[0025] The limiting plate 20 is provided with a flip hole 21 adapted to the rotating shaft 30. The limiting plate 20 is sleeved on the rotating shaft 30 through the flip hole 21, and the flip hole 21 and the rotating shaft 30 are connected by a clearance fit. This allows the limiting plate 20 to be flipped between the first fixed plate 11 and the second fixed plate 12. By flipping the limiting plate 20, it can abut against the setting frame trolley, thereby limiting the setting frame trolley and preventing it from rolling back, ensuring the normal operation of the acid etching process and improving product quality. Flipping the limiting plate 20 removes the limitation on the setting frame trolley, facilitating the movement of the setting frame trolley to the next process and improving the reliability of the structure.
