Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a spray thinning device for glass etching lines. Background Technology

[0002] In the glass processing industry, especially in industries with extremely high requirements for glass thickness accuracy and surface quality, such as electronic displays and optical instruments, the spray thinning device for glass etching lines is a key piece of equipment for achieving precise glass thinning. Its core principle is to spray the etching solution evenly onto the glass surface through a nozzle, and use chemical etching to achieve glass thinning to meet the product's demand for lightness, thinness and high optical performance.

[0003] However, in existing technologies, when glass enters the spray thinning device for processing, it often relies on manual feeding and positioning. Due to the lack of specialized feeding guides and positioning structures, it is difficult for workers to accurately and stably place the glass in the area directly below the nozzle. This positioning deviation will directly cause the etching solution sprayed from the nozzle to not evenly cover the glass surface. Some areas will have too much etching solution sprayed, while other areas will have too little, resulting in uneven glass thinning and seriously affecting the processing accuracy and product quality of the glass.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: when workers use the spray device to process glass, they cannot accurately place the glass in the appropriate position, resulting in the nozzle not being able to spray the etching solution evenly onto the glass surface, causing a reduction in the processing accuracy of the glass. Utility Model Content

[0005] The technical problem to be solved by this utility model is that in the prior art, when workers use the spray device to process glass, they cannot accurately place the glass in the appropriate position, which results in the nozzle not being able to spray the etching solution evenly onto the glass surface, causing a reduction in the processing accuracy of the glass. To address this, we propose a spray thinning device for glass etching lines.

[0006] To achieve the above objectives, this application adopts the following technical solution: a spray thinning device for glass etching lines, comprising a spray device body, a liquid storage tank installed on the surface of the spray device body, three nozzles installed on the inner wall of the spray device body, a feeding device provided on the surface of the spray device body, the feeding device comprising a U-shaped plate, the U-shaped plate being fixedly connected to the surface of the spray device body, two sliding grooves being formed on the surface of the U-shaped plate, a feeding plate being slidably connected to the surfaces of the two sliding grooves, and a handle being fixedly connected to the surface of the feeding plate.

[0007] Preferably, two connecting rods are fixedly connected to the surface of the U-shaped plate, one end of the connecting rod is fixedly connected to a connecting plate, a limiting rod is slidably inserted into the connecting plate, and two limiting grooves are opened on the surface of the feeding plate.

[0008] Preferably, the connecting rod is rotatably connected to a baffle plate on its arc surface, and the baffle plate has a baffle groove on its surface.

[0009] Preferably, a torsion spring is fitted on the arc surface of the connecting rod, and the two ends of the torsion spring are fixedly connected to the connecting plate and the blocking plate respectively. Two blocking blocks are fixedly connected to the surface of the U-shaped plate.

[0010] Preferably, the surface of the spray device body is provided with a protective device, which includes two square rods. Both square rods are fixedly connected to the surface of the spray device body. A rotating rod is rotatably connected to the side of the two square rods that are close to each other. A protective plate is fixedly connected to the arc surface of the rotating rod.

[0011] Preferably, one end of the square rod is fixedly connected to a fixing rod, the arc surface of the fixing rod is slidably connected to an operating plate, the surface of the operating plate is fixedly connected to a plug rod, and the surface of the protective plate has two slots.

[0012] Preferably, a spring is fitted onto the arc surface of the fixing rod, and the two ends of the spring are fixedly connected to the square rod and the operating plate, respectively.

[0013] The technical effects and advantages of this utility model are as follows: In this invention, a feeding device is installed to precisely position the glass directly below the nozzle. The U-shaped plate in the feeding device forms a stable sliding fit structure with the feeding plate. The operator can push the feeding plate along the chute to move it precisely, ensuring that the glass can be accurately delivered to the preset processing position directly below the nozzle. This precise positioning effectively avoids the problem of uneven etching solution spraying caused by positional deviation when manually placing the glass, thus ensuring the uniformity of etching solution coverage in all areas of the glass surface from the source.

[0014] In this invention, by setting a protective device, the button of the spray device body can be protected. The protective plate in the protective device can rotate around the square rod under the drive of the rotating rod to cover the button of the spray device body, forming a physical barrier. This barrier can isolate the button from the external environment, preventing the operator from accidentally touching the button during operation, providing reliable protection for the button, and thus ensuring that the amount of etching liquid sprayed from the nozzle is always within a suitable range, providing stable process conditions for glass processing.

Detailed Implementation

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] Reference Figure 1As shown, this utility model provides a technical solution: a spray thinning device for a glass etching line, including a spray device body 1, a liquid storage tank 4 installed on the surface of the spray device body 1, three nozzles 5 installed on the inner wall of the spray device body 1, and a feeding device 2 provided on the surface of the spray device body 1. By setting the feeding device 2, the glass can be placed directly below the nozzles 5, avoiding the situation where the operator cannot accurately place the glass in the appropriate position when using the spray device body 1 to process the glass, resulting in the nozzles 5 not being able to spray the etching liquid evenly on the glass surface, thus reducing the processing accuracy of the glass. The surface of the spray device body 1 is provided with a protective device 3, which can protect the buttons of the spray device body 1, preventing the operator from accidentally touching the buttons of the spray device body 1 when processing the glass, which would change the operating parameters of the spray device body 1, increase or decrease the amount of etching liquid sprayed by the nozzles 5, and cause the glass processing quality to be unqualified.

[0018] Reference Figure 2 and Figure 3 As shown in this embodiment: the feeding device 2 includes a U-shaped plate 201, which is fixedly connected to the surface of the spraying device body 1. Two grooves 202 are formed on the surface of the U-shaped plate 201, and a feeding plate 203 is slidably connected to the surfaces of the two grooves 202. A handle 204 is fixedly connected to the surface of the feeding plate 203. Two connecting rods 205 are fixedly connected to the surface of the U-shaped plate 201, and a connecting plate 206 is fixedly connected to one end of each connecting rod 205. A limiting rod 207 is slidably inserted into the connecting plate 206. The feeding plate 203 has two limiting grooves, which achieve the effect of fixing the feeding plate 203 and preventing it from sliding on the surface of the U-shaped plate 201. The connecting rods 205... A blocking plate 208 is rotatably connected to the arc surface. The surface of the blocking plate 208 has a blocking groove, which can restrict the movement of the limiting rod 207. This prevents the limiting rod 207 from moving downward under the action of gravity when the operator moves the feeding plate 203, and avoids the limiting rod 207 from colliding with the feeding plate 203 and being damaged. A torsion spring 209 is sleeved on the arc surface of the connecting rod 205. The two ends of the torsion spring 209 are fixedly connected to the connecting plate 206 and the blocking plate 208, respectively. Two blocking blocks 210 are fixedly connected to the surface of the U-shaped plate 201. The torsion force 209 of the torsion spring causes the blocking plate 208 to automatically reset, reducing the number of operation steps for the operator and facilitating the next operation.

[0019] Reference Figure 4 and Figure 5As shown in this embodiment: the protective device 3 includes two square rods 31, both of which are fixedly connected to the surface of the spray device body 1. A rotating rod 32 is rotatably connected to one side of the two square rods 31 that is close to each other. A protective plate 33 is fixedly connected to the arc surface of the rotating rod 32. A fixing rod 34 is fixedly connected to one end of the square rod 31. An operating plate 35 is slidably connected to the arc surface of the fixing rod 34. An insertion rod 36 is fixedly connected to the surface of the operating plate 35. Two slots are provided on the surface of the protective plate 33 to achieve the effect of fixing the protective plate 33 and preventing the protective plate 33 from rotating, which would reduce the protective effect of the protective plate 33. A spring 37 is sleeved on the arc surface of the fixing rod 34. The two ends of the spring 37 are fixedly connected to the square rod 31 and the operating plate 35 respectively. The rebound force of the spring 37 achieves the effect of automatically inserting the insertion rod 36, while restricting the movement of the insertion rod 36 and improving the stability of the insertion rod 36 when fixing the protective plate 33.

[0020] Working principle: When the operator needs to process glass, the limit rod 207 is moved. When the limit rod 207 is completely disengaged from the surface of the limiting groove of the feeding plate 203, the limit rod 207 releases its fixation to the feeding plate 203. The blocking plate 208 is rotated. When the blocking plate 208 is rotated to the appropriate position, the limit rod 207 is located directly above the blocking groove of the blocking plate 208. The limit rod 207 is then inserted into the surface of the blocking groove of the blocking plate 208. The handle 204 is moved, causing the feeding plate 203 to slide on the surface of the slide 202. When the feeding plate 203 moves to the appropriate position, the operator can place the glass to be processed on the slide. Place the material onto the surface of the feeding plate 203. After placement, move the handle 204 to move the feeding plate 203. When the feeding plate 203 returns to its original position, move the limiting rod 207. When the limiting rod 207 completely disengages from the surface of the blocking groove of the blocking plate 208, the torque of the torsion spring 209 causes the blocking plate 208 to rotate. When the surface of the blocking plate 208 contacts the blocking block 210, the blocking plate 208 rotates to the appropriate position. Move the limiting rod 207. When the limiting rod 207 is inserted into the surface of the limiting groove of the feeding plate 203, the limiting rod 207 can fix the feeding plate 203. At this time, the operator can use the spray device body 1 to process the glass.

[0021] When staff need to use the protective plate 33 to protect the buttons on the main body 1 of the spray device, they move the operating plate 35, stretching the spring 37. The operating plate 35 then moves the insert rod 36. Once the insert rod 36 is in the appropriate position, the protective plate 33 is rotated, causing the rotating rod 32 to rotate. After the protective plate 33 effectively protects the buttons on the main body 1 of the spray device, the operating plate 35 is released. The rebound force of the spring 37 causes the operating plate 35 to move, which in turn moves the insert rod 36 until it is inserted into the surface of the slot in the protective plate 33. At this point, the insert rod 36 can fix the protective plate 33 in place. When staff need to use the buttons on the main body 1 of the spray device, they simply open the protective plate 33.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
