[0037] As mentioned in the above background technology, the glass substrate is an important component of the flat panel display, and the cleanliness of the glass substrate is one of the important guarantees to ensure the quality of the flat panel display. For this reason, the glass substrate needs to be cleaned by the sponge roller of the glass cleaning equipment during the production process. For the newly purchased sponge roller, according to the requirements of the process, it needs to be soaked in the soaking tank before it can be installed on the cleaning equipment for use. Usually, multiple sponge rollers need to be soaked in the soaking tank at the same time. In the soaking process, in order to avoid the sponge rollers from squeezing each other and affecting their use effect, it is necessary to place multiple brackets in the soaking tank to support multiple sponge rollers. Since multiple brackets are arranged up and down, there will inevitably be a problem of affecting the placement of the sponge roller on the lower bracket due to the obstruction of the upper bracket. Based on this, the inventor of the present application provides a sponge roller soaking tank for a glass substrate cleaning machine in one or more embodiments, which is rotatably arranged on the inner wall of the box body through a cross bar, thereby avoiding the problem of the upper bracket obstructing and affecting the placement of the sponge roller on the lower bracket, and solving one or more problems in the prior art.

[0038] In view of the above-mentioned technical problems, the utility model provides a sponge roller soaking tank for a glass substrate cleaning machine, such as Figure 1 and Figure 2As shown, it includes: a box body 1, an opening is provided on the upper part of the box body 1, and the box body 1 includes two opposite inner walls 11; at least one upper bracket 2, the upper bracket 2 is arranged in the box body 1, and each upper bracket 2 includes two cross bars 21 for respectively supporting the two ends of the sponge roller shaft 6, the two cross bars 21 are arranged in parallel at the same height, the cross bar 21 includes a front end and a bottom end, and the bottom ends of the two cross bars 21 can be rotatably connected to the same inner wall 11 around the axis in the vertical direction, so that the front ends of the two cross bars 21 are away from or close to the inner wall 11; at least one bottom bracket 3, the bottom bracket 3 is arranged in the box body 1 and below the upper bracket 2, and each bottom bracket 3 includes two support rods 31 for supporting the two ends of the sponge roller shaft 6, the two support rods 31 are arranged in parallel at the same height, one end of the support rod 31 is connected to one inner wall 11, and the other end is connected to the other inner wall 11.

[0039] Specifically, when placing the sponge roller 6 on the bottom bracket 3, first rotate the cross bar 21 of the upper bracket 2 so that the front end of the cross bar 21 is attached to the inner wall 11 of the box body 1, so that the cross bar 21 is in an empty position, that is, the empty position is that the cross bar 21 is parallel to the inner wall 11 of the box body 1, and then place the sponge roller 6 on the bottom bracket 3, and then rotate the cross bar 21 so that the front end of the cross bar 21 is away from the inner wall 11 of the box body 1, so as to rotate the cross bar 21 to the placement position, that is, the placement position is that the cross bar 21 is perpendicular to the inner wall 11 of the box body 1, and then place the sponge roller 6 on the upper bracket 2. After the sponge roller 6 is placed in the box body 1, water is injected into the box body 1 to soak the sponge roller 6; after the sponge roller 6 is soaked, first take out the sponge roller 6 placed on the upper bracket 2, and then rotate the cross bar 21 to make it turn to the empty position, and then take out the sponge roller 6 on the bottom bracket 3. It should be understood that although the embodiments of the present application are described by taking a specific number and a specific position of the upper bracket 2 and the bottom bracket 3 as an example, the present application is not limited thereto. For example, as needed, a plurality of upper brackets 2 and a plurality of bottom brackets 3 can be arranged in the box body 1. The plurality of upper brackets 2 can be arranged on the same horizontal plane or staggered up and down. The spacing between the two cross bars 21 in each upper bracket 2 can be different to achieve support for sponge rollers 6 of different lengths. The two support rods 31 of each lower bracket cooperate to achieve support for sponge rollers 6 of different lengths, thereby achieving the technical effect of the present application. Furthermore, the material of the cross bar 21 and the support rod 31 is not limited, as long as it is ensured to have sufficient strength. Since the cross bar 21 and the support rod 31 are immersed in water for a long time, preferably, the cross bar 21 and the support rod 31 are made of stainless steel. Furthermore, if Figure 1 and Fig.10 As shown, the box body 1 can also be placed on the support frame 4 to facilitate the operation of the staff.

[0040] Compared with the prior art, the sponge roller soaking tank for a glass substrate cleaning machine of the present application is rotatably arranged on the inner wall 11 of the box body 1 through a cross bar 21, thereby avoiding the problem of the upper bracket 2 blocking and affecting the placement of the sponge roller 6 on the lower bracket.

[0041] In some embodiments, Figure 3 As shown, the bottom end of the cross bar 21 is rotatably connected to the inner wall 11 through a connecting piece, and the connecting piece includes a sleeve 22 and a rotating shaft 23. The sleeve 22 is arranged on the inner wall 11 along the vertical direction, and the rotating shaft 23 is rotatably arranged in the sleeve 22 around the AA axis and its upper and lower ends extend out of the sleeve 22. The upper and lower ends of the bottom of the cross bar 21 are respectively connected to the upper and lower ends of the rotating shaft 23. The rotation of the cross bar 21 is achieved by the connecting piece. Specifically, the sleeve 22 and the rotating shaft 23 can also be made of stainless steel. The sleeve 22 can be connected to the inner wall 11 of the box body 1 by welding. In order to ensure the connection strength of the two, full welding is required. The upper and lower ends of the bottom end of the cross bar 21 can be connected to the upper and lower ends of the rotating shaft 23 by bolts. In order to ensure the connection strength of the two, high-strength bolts can be used for connection. Furthermore, since the cross bar 21 is a cantilever structure supported at one point, a cable (not shown in the figure) can be provided on the cross bar 21 to increase the structural strength and stability of the upper bracket 2. One end of the cable is connected to the front end of the cross bar 21, and the other end is rotatably connected to the inner wall 11 of the box body 1 above the bottom end of the cross bar 21. Preferably, the cable is made of stainless steel cable.

[0042] In some embodiments, Figure 3 As shown, a first locking mechanism 24 for locking the cross bar 21 in a preset position is provided on the rotating shaft 23. The cross bar 21 can be locked in the preset position by the first locking mechanism 24, thereby avoiding the problem that the cross bar 21 rotates by itself and causes the sponge roller 6 placed thereon to fall off or affects the placement and removal of the sponge roller 6 placed on the bottom bracket 3. Specifically, when the sponge roller 6 is placed on the upper bracket 2, the preset position is the placement position, and the first locking mechanism 24 locks the cross bar 21 in the placement position; when the sponge roller 6 is placed and removed on the lower bracket, the preset position is the vacant position, and the first locking mechanism 24 locks the cross bar 21 in the vacant position. Further, as Figure 4 and Figure 5 As shown, the first locking mechanism 24 includes a pin 241, a horizontal through hole 231 is opened at the end of the rotating shaft 23, and a bottom groove 111 is opened on the inner wall 11 of the box body 1 at the same height as the horizontal through hole 231. The pin 241 passes through the horizontal through hole 231 and is inserted into the bottom groove 111, thereby locking the cross bar 21 at a preset position.

[0043] In some embodiments, Figure 6As shown, a first groove 25 for fixing the end of the sponge roller 6 is provided at the top of the cross bar 21 along its width direction, and a plurality of first grooves 25 are provided for fixing the ends of a plurality of sponge rollers 6. The sponge roller 6 can be fixed to the cross bar 21 through the first grooves 25, thereby preventing the sponge roller 6 from rolling on the cross bar 21 and falling off.

[0044] In some embodiments, Figure 7 As shown, a fixing piece for fixing the end of the sponge roller shaft 6 is arranged on the top of the cross bar 21, and the fixing piece includes a plurality of ends for fixing a plurality of sponge roller shafts 6. The fixing piece includes a bottom plate 26 and two vertical plates 27. The bottom plate 26 is slidably arranged on the top of the cross bar 21 along the length direction of the cross bar 21, and the two vertical plates 27 are respectively arranged on the two ends of the bottom plate 26 and a clamping space 28 for clamping the end of the sponge roller shaft 6 is formed between the two. The sponge roller shaft 6 can be fixed on the cross bar 21 by the fixing piece, so as to avoid the problem of the sponge roller shaft 6 rolling on the cross bar 21 and falling. In addition, the spacing between the fixing pieces can be adjusted by sliding the bottom plate 26, so as to avoid the problem of mutual squeezing caused by placing sponge roller shafts 6 of different diameters on the cross bar 21. Specifically, the bottom plate 26 and the vertical plates 27 can be made of stainless steel, and the cross section of the clamping space 28 can be a trapezoid with a large top and a small bottom, so as to facilitate the taking and placing of the sponge roller shaft 6.

[0045] In some embodiments, Figure 8 and Fig. 9 As shown, a second groove 29 is provided on the top of the cross bar 21 along its length direction, and a convex strip 261 is provided on the bottom of the bottom plate 26, and the convex strip 261 is slidably disposed in the second groove 29. The second groove 29 and the convex strip 261 enable the fixing member to slide on the cross bar 21. Specifically, the second groove 29 and the convex strip 261 are both inverted T-shaped in cross section, which enables the fixing member to slide while avoiding the problem of the fixing member slipping off the cross bar 21.

[0046] In some embodiments, Figure 8 and Fig. 9 As shown, a second locking mechanism 262 is provided on the bottom plate 26 to lock the fixing member on the cross bar 21. The fixing member can be locked on the cross bar 21 by the second locking mechanism 262, thereby avoiding the problem of the fixing member sliding by itself. Specifically, the second locking mechanism 262 includes a screw 263, and a vertical threaded through hole 264 is provided on the end of the bottom plate 26. One end of the screw 263 passes through the vertical threaded through hole 264 and abuts against the cross bar 21, thereby pressing the fixing member on the cross bar 21.

[0047] In some embodiments, Figure 1As shown, the upper and lower ends of the side wall of the box body 1 are respectively provided with a water injection port 12 and a water discharge port 13. In order to ensure the cleanliness of the sponge roller 6 during the soaking process, the soaking water in the box body 1 needs to be replaced after being used for a period of time and becoming dirty. The dirty water in the box body 1 can be discharged through the water discharge port 13, and then clean water can be injected into the box body 1 through the water injection port 12. Specifically, valves are provided on the water injection port 12 and the water discharge port 13 to control the opening and closing of the water injection port 12 and the water discharge port 13.

[0048] In some embodiments, the sponge roller soaking tank further includes a filtering device (not shown in the figure), the water inlet of the filtering device is connected to the water outlet 13, and the water outlet is connected to the water injection port 12. The sewage discharged from the housing 1 can be filtered and purified by the filtering device and then discharged into the housing 1 for reuse, thereby realizing the reuse of water resources. Specifically, the water filtering device is a prior art and will not be described in detail here.

[0049] In some embodiments, Figure 1 As shown, a box cover 5 is provided on the opening of the box body 1. The box cover 5 can seal the opening, thereby preventing dust and sundries in the environment from falling into the box body 1 and polluting the soaking water in the box body 1.

[0050] In summary, compared with the prior art, the present invention provides a sponge roller soaking tank for a glass substrate cleaning machine, which is rotatably arranged on the inner wall 11 of the box body 1 through the cross bar 21, thereby avoiding the problem of the upper bracket 2 blocking and affecting the placement of the sponge roller 6 on the lower bracket; the rotation of the cross bar 21 is realized by the connecting piece; the problem of the cross bar 21 rotating on its own is avoided by the first locking mechanism 24; the problem of the sponge roller 6 slipping off the cross bar 21 is avoided by the first groove 25 and the fixing piece; the problem of sponge rollers 6 of different diameters being squeezed against each other when placed on the cross bar 21 is avoided by the sliding of the bottom plate 26 on the cross bar 21; the problem of the fixing piece sliding on its own is avoided by the second locking mechanism 262; and the reuse of water resources is achieved by the filtering device.
