Description

Technical Field

[0001] This invention relates to the field of glass cleaning machines, and more specifically to a curved glass cleaning machine. Background Technology

[0002] Currently, glass cleaning machines include a glass plate conveying device and a glass plate cleaning device. The glass plate conveying device drives the glass plate to move horizontally via a conveyor belt. The glass plate cleaning device includes upper and lower brush rollers. The glass plate conveying device has a gap so that the lower brush roller can contact the bottom of the glass plate. When the glass plate passes between the upper and lower brush rollers, water is sprayed onto the glass plate, thus cleaning both the upper and lower surfaces of the glass plate. However, some glass plates are curved. For example, the outer wall of a curved glass plate is a cylindrical part. Since the existing brush rollers rotate on a fixed axis, they cannot reach the concave parts of the curved glass plate. Some manufacturers have lengthened the bristles of the brush rollers so that they can reach into the concave parts of the curved glass plate. However, because the rigidity of the bristles is greatly reduced, the bottom of the concave part of the curved glass plate is less scrubbed, while the two ends of the concave part are more scrubbed. This results in uneven cleaning of the inner wall of the curved glass plate, and the outer wall of the curved glass plate also encounters the same problem. Therefore, it is necessary to improve the existing cleaning machines for curved glass plates. Summary of the Invention

[0006] Preferably, the glass plate conveying device includes two conveyor belt assemblies, with a gap between the two conveyor belt assemblies for the lower brush roller to pass through; it also includes a movable bridge device for supporting the lower end of the curved glass plate so that the curved glass plate passes through the gap, the movable bridge device including a left bridge plate and a right bridge plate, the movable bridge device including a bridge plate translation drive assembly, the left bridge plate and the right bridge plate being driven to move left and right respectively by the corresponding bridge plate translation drive assembly, the right end of the left bridge plate being able to abut against the left end of the right bridge plate.

Detailed Implementation

[0030] The present invention will now be further described with reference to the accompanying drawings.

[0031] The curved glass washing machine of the present invention, such as Figures 1 to 3 As shown, the curved glass washing machine of the present invention includes a glass plate conveying device 1 for moving the curved glass plate 99 in the left-right direction, and also includes a washing device 3, such as... Figure 3 and Figure 12 As shown, the cleaning device 3 includes an upper brush roller 31 for cleaning the upper surface of the curved glass plate 99 and a lower brush roller 32 for cleaning the lower surface of the curved glass plate 99, as... Figure 13 As shown, the cleaning device 3 includes a brush roller rotation drive assembly 33 (it should be noted that only...) Figure 13The diagram schematically illustrates the brush roller rotation drive assembly 33. The upper brush roller 31 and lower brush roller 32 are driven to rotate by their respective brush roller rotation drive assemblies 33. Figure 12 As shown, the cleaning device 3 includes a brush roller lifting drive assembly 30. The upper brush roller 31 and the lower brush roller 32 are driven to rise and fall by the corresponding brush roller lifting drive assembly 30, so the upper brush roller 31 and the lower brush roller 32 can move independently.

[0032] like Figure 3 As shown, a curved glass plate 99 is placed on a glass plate conveying device 1 with its inner surface facing down (i.e., its concave side facing down), ensuring the curved glass plate 99 is stably positioned on the glass plate conveying device 1. The glass plate conveying device 1 then transports the curved glass plate 99 to the corresponding position on the cleaning device 3. For example, the curved glass plate 99 moves from left to right. The up-and-down movement of the upper brush roller 31, combined with the horizontal movement of the curved glass plate 99, allows the upper brush roller 31 to brush along the top (i.e., the outside) of the curved glass plate 99, resulting in a uniform brushing effect and effectively cleaning the top of the curved glass plate 99. Similarly, due to the lower brush roller 32... The vertical movement of the upper and lower brush rollers, combined with the horizontal movement of the curved glass plate 99, allows the lower brush roller 32 to brush the lower surface (inner surface) of the curved glass plate 99. Specifically, the lower brush roller 32 is driven to rotate by the corresponding brush roller rotation drive assembly 33. When the lower brush roller 32 rotates, the bristles on the lower brush roller 32 brush the inner surface of the curved glass plate 99. This avoids the need for the lower brush roller 32 and the upper brush roller 31 to have long bristles, and can effectively brush both the upper and lower surfaces of the curved glass plate 99. This gives the bristles a suitable rigidity, which is beneficial for applying a large brushing force to the curved glass plate 99, thus facilitating the cleaning of the curved glass plate 99. During this process, water is sprayed onto both the upper and lower surfaces of the curved glass plate 99. As can be seen from the above, the curved glass cleaning machine of the present invention is beneficial for achieving a uniform and effective cleaning effect on both the inner and outer surfaces of the curved glass plate.

[0033] Since the curved glass plate 99 is placed on the glass plate conveying device 1, and both ends of the curved glass plate 99 must be supported simultaneously, otherwise the curved glass plate 99 will tip over, the support for the curved glass plate 99 needs to be continuous during the conveying process. If the glass plate conveying device 1 is set to continuously support the curved glass plate 99, it will cause the lower brush roller 32 to interfere with the glass plate conveying device 1. A feasible solution is that the glass plate conveying device 1 supports the front and rear edges of the curved glass plate 99, while the lower brush roller 32 is located within the front and rear edges of the curved glass plate 99, so that the lower brush roller 32 avoids the glass plate conveying device 1. However, this will prevent the front and rear edges of the curved glass plate 99 from being brushed.

[0034] Furthermore, such as Figure 4 As shown, the glass plate conveying device 1 includes two conveyor belt assemblies 11, with a gap 110 between the two conveyor belt assemblies 11 for the lower brush roller 32 to pass through; Figures 1 to 3 As shown, the curved glass washing machine of the present invention also includes a movable bridge device 2 for supporting the lower end of the curved glass plate 99 so that the curved glass plate 99 passes over the gap 110, such as... Figure 6 As shown, the movable bridge device 2 includes a left bridge plate 21 and a right bridge plate 22. The movable bridge device 2 also includes a bridge plate translation drive assembly 20. The left bridge plate 21 and the right bridge plate 22 are driven to move left and right respectively by the corresponding bridge plate translation drive assembly 20. The right end of the left bridge plate 21 can abut against the left end of the right bridge plate 22, so that the left bridge plate 21 and the right bridge plate 22 combine to form a bridge structure supporting the curved glass plate 99 across the gap 110. When the left bridge plate 21 and the right bridge plate 22 are relatively separated, the lower brush roller 32 can pass upward or downward through the gap 110 (also passing between the left bridge plate 21 and the right bridge plate 22). More specifically, as... Figure 6 As described above, when the right end of the curved glass plate 99 detaches from the conveyor belt assembly 11 located on the left, but the right end of the curved glass plate 99 is supported by the left bridge plate 21, it is prevented from falling downwards into the gap 110. That is to say, the upper end of the left bridge plate 21 is flush with the conveying surface of the conveyor belt assembly 11, because at this time the right end of the left bridge plate 21 is abutting against the left end of the connecting right bridge plate 22, while the conveyor belt assembly 11 located on the left still drives the left end of the curved glass plate 99. Then the right end of the curved glass plate 99 moves onto the left end of the right bridge plate 22, as... Figure 7 As shown, after the right end of the curved glass plate 99 moves onto the right bridge plate 22, the right bridge plate 22 can be driven to the right by the corresponding bridge plate translation drive assembly 20. At the same time, the left bridge plate 21 is also driven to the left by the corresponding bridge plate translation drive assembly 20. Thus, the movable bridge formed by the right bridge plate 22 and the left bridge plate 21 is disengaged, as... Figure 7 As shown, the lower brush roller 32 can be driven upward by the corresponding brush roller lifting drive assembly 30, and the lower brush roller 32 begins to brush the inner surface of the lower right end of the curved glass plate 99; then, as... Figure 8 As shown, since the lower brush roller 32 has already passed upward through the gap 110, the lower brush roller 32 moves to the left relative to the curved glass plate 99 above the movable bridge. During this process, the lower brush roller 32 moves up and down to match the arc shape of the inner surface of the curved glass plate 99; then, as... Figure 9As shown, the left end of the curved glass plate 99 leaves the conveyor belt assembly 11 located on the left, but the right end of the curved glass plate 99 continues to move to the right due to the conveyor belt assembly 11 located on the right. At this time, the lower brush roller 32 moves to the lower left position of the curved glass plate 99, and the lower brush roller 32 can now detach downwards from the curved glass plate 99. Therefore, the left bridge plate 21 moves to the right, and the right bridge plate 22 moves to the left simultaneously. The lower brush roller 32 then passes downwards through the gap 110, as... Figure 10 As shown, the left bridge plate 21 and the right bridge plate 22 are spliced ​​together again to form a bridge, allowing the left end of the curved glass plate 99 to move from the left bridge plate 21 to the right bridge plate 22. The curved glass plate 99 is then completely transferred to the conveyor belt assembly 11 on the right side. As the curved glass plate 99 crosses the gap 110, the upper brush roller 31 simultaneously cleans the top surface of the curved glass plate 99. As explained above, by setting the movable bridge device 2, the lower brush roller 32 can pass through the gap 110, but the curved glass plate 99 is prevented from falling into the gap 110. This also allows the brush bristles of the lower brush roller 32 to be set to be wider in the front-to-back direction (i.e., in the direction of the rotation axis of the lower brush roller 32) than the front-to-back width of the curved glass plate 99, ensuring that the entire inner surface (bottom surface) of the curved glass plate 99 receives effective cleaning.

[0035] Furthermore, such as Figure 1 and Figure 6 As shown, the curved glass washing machine of the present invention also includes a frame 5, and a bridge plate translation drive assembly 20 including a bridge plate motor assembly 201, a gear and rack transmission assembly 203, a crossbeam 204, and a drive shaft 205. The crossbeam 204 is slidably connected to the frame 5, and the drive shaft 205 is rotatably connected to the crossbeam 204, that is, the axis of the drive shaft 205 and the crossbeam 204 move synchronously. Figure 11 As shown, the front and rear ends of the drive shaft 205 are connected to the frame 5 via corresponding gear and rack transmission assemblies 203. Specifically, the gear and rack transmission assembly 203 includes gears and racks. The rack is mounted on the frame 5, and the gears are respectively mounted on the front and rear ends of the drive shaft 205 via flat keys. The gears mesh with the corresponding racks. The bridge plate motor assembly 201 drives the drive shaft 205 to rotate, that is, the bridge plate motor assembly 201 can drive the gears to rotate. Figure 11 As shown, the left bridge plate 21 and the right bridge plate 22 are arranged laterally on the corresponding crossbeams 204, which helps to improve the stability of the lower end of the support for the curved glass plate 99. Since the front and rear ends of the drive shaft 205 are connected to the frame 5 through the corresponding gear and rack transmission assembly 203, when the drive shaft 205 rotates, the gears on both ends of the drive shaft 205 rotate synchronously, which helps to enable the front and rear ends of the crossbeam 204 to move synchronously, so that the left bridge plate 21 and the right bridge plate 22 can move stably and reliably.

[0036] Furthermore, such as Figure 6 and Figure 11 As shown, the bridge plate translation drive assembly 20 includes a slide plate 206, a crossbeam 204, and a bridge plate motor assembly 201 mounted on the slide plate 206. That is, the crossbeam 204 is slidably connected to the frame 5 via the slide plate 206. Specifically, the bottom of the slide plate 206 is connected to the frame 5 via a corresponding linear guide rail. Since the bridge plate motor assembly 201 is mounted on the slide plate 206, it can move with the crossbeam 204. The bridge plate motor assembly 201 is driven by the bridge plate transmission belt 202 to connect to the drive shaft 205. The bridge motor assembly 201 includes a servo motor and a reducer. The bridge drive belt 202 is a synchronous belt. Since the right end of the left bridge 21 needs to be close to the left end of the right bridge 22, the right end of the left bridge 21 may slightly collide with the left end of the right bridge 22. By setting the bridge drive belt 202 to be a relatively flexible transmission structure, when the right end of the left bridge 21 contacts the left end of the right bridge 22, the bridge drive belt 202 can slightly elastically extend to buffer the collision and avoid the reducer of the bridge motor assembly 201 being easily damaged by the impact.

[0037] Furthermore, such as Figure 6 As shown, the drive shaft 205 passes through the corresponding crossbeam 204, that is, the crossbeam 204 is fitted over the drive shaft 205, which helps to make the combined structure of the drive shaft 205 and the crossbeam 204 compact. The front and rear ends of the drive shaft 205 protrude from the crossbeam 204 respectively. Specifically, the crossbeam 204 can be made of aluminum profile as the base, and the two ends of the aluminum profile are covered with steel end plates. The drive shaft 205 is connected to the end plates mentioned above through bearings.

[0038] Furthermore, such as Figure 5 As shown, the conveyor belt assembly 11 includes a conveyor belt support beam 111, on which a conveyor belt is mounted (note that the conveyor belt is not shown in any of the attached drawings). Specifically, the conveyor belt support beam 111 is made of aluminum profile, and conveyor belt pulleys are respectively provided at the left and right ends of the conveyor belt support beam 111. The conveyor belt is fitted over the conveyor belt pulleys and the conveyor belt support beam 111, and the upper part of the conveyor belt is supported by the upper part of the conveyor belt support beam 111. In other words, each conveyor belt support beam 111 has one corresponding conveyor belt. Figure 5As shown, the conveyor belt support beams 111 are arranged in the front-to-back direction, which helps to increase the support range for the lower end of the curved glass plate 99, while avoiding the need to purchase wide conveyor belts. The conveyor belt assembly 11 includes a conveyor belt drive shaft 112 and a conveyor belt motor assembly 113. The conveyor belt motor assembly 113 drives the conveyor belts through the conveyor belt drive shaft 112. Specifically, each of the above-mentioned conveyor belts is connected to a corresponding drive wheel. Each of the above-mentioned drive wheels is mounted on the conveyor belt drive shaft 112 by a flat key. The conveyor belt drive shaft 112 is connected to the hollow shaft of the worm gear reducer of the conveyor belt motor assembly 113 by a corresponding flat key. That is to say, the conveyor belt drive shaft 112 passes through the hollow shaft. Thus, only one conveyor belt motor assembly 113 drives all the conveyor belts of the conveyor belt assembly 11, which helps to simplify the transmission structure.

[0039] like Figure 4 As shown, the two conveyor belt assemblies 11 are arranged symmetrically to each other, which allows the same conveyor belt to be purchased for both conveyor belt assemblies 11, which helps to simplify the manufacturing process of the glass plate conveying device 1.

[0040] Furthermore, such as Figure 12 and Figure 13 As shown, the brush roller lifting drive assembly 30 includes a brush roller lifting motor assembly 301, a lead screw assembly 302, and a lifting plate 303; the curved glass washing machine of the present invention also includes a gantry frame 300 for the passage of the curved glass plate 99. The lifting plate 303 is slidably connected to the gantry frame 300 via corresponding linear guide rails. The brush roller lifting motor assembly 301 drives the lifting plate 303 via the lead screw assembly 302. Specifically, the nut of the lead screw assembly 302 is installed on the lifting plate 303, and the upper end of the lead screw of the lead screw assembly 302 is connected to the worm gear of the corresponding worm gear reducer. The output shaft of the brush roller lifting motor assembly 301 is connected to a horizontally arranged drive shaft. The front and rear ends of the drive shaft are connected to the worm gear of the corresponding worm gear reducer. The output shaft of the brush roller lifting motor assembly 301 drives the drive shaft to rotate, and the drive shaft synchronously drives the front and rear worm gear reducers to rotate, so that the two lead screws rotate synchronously, and the two corresponding lifting plates 303 move up and down synchronously. Figure 12 As shown, the front and rear ends of the upper brush roller 31 are rotatably connected to the corresponding lifting plates 303, and the front and rear ends of the lower brush roller 32 are rotatably connected to the corresponding lifting plates 303. Thus, the upper brush roller 31 and the lower brush roller 32 can achieve synchronous movement of their front and rear ends by being driven by only one corresponding brush roller lifting motor assembly 301, and the upper brush roller 31 and the lower brush roller 32 can move independently. The structure of the brush roller lifting drive assembly 30 is simple and reliable.

[0041] Furthermore, such as Figure 13As shown, the brush roller rotation drive assembly 33 includes a brush roller rotation motor assembly 331 and a brush roller transmission belt 332. The brush roller rotation motor assembly 331 is mounted on the corresponding lifting plate 303, so that the brush roller rotation motor assembly 331 can move with the lifting plate 303. The upper brush roller 31 and the lower brush roller 32 are respectively connected to the corresponding brush roller rotation motor assembly 331 through the corresponding brush roller transmission belt 332, so the upper brush roller 31 and the lower brush roller 32 can rotate independently.

[0042] Furthermore, such as Figure 3 As shown, both the upper brush roller 31 and the lower brush roller 32 are cylindrical in shape. That is to say, the brush area of ​​the upper brush roller 31 is cylindrical, which is beneficial for adapting to the brushing of curved glass plates.

[0043] Furthermore, such as Figure 2 and Figure 3 As shown, the curved glass cleaning machine of the present invention also includes a water receiving tray assembly 4, which is located below the upper brush roller 31 and the lower brush roller 32 to prevent sewage from flowing to the ground. Specifically, the water receiving tray assembly 4 includes three water receiving trays: one is located below the right end of the left conveyor belt assembly 11, one is located below the left end of the right conveyor belt assembly 11, and one is located below the gap 110. This facilitates the large-scale reception of sewage flowing down from the curved glass plate 99.
