DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0035] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] In this embodiment, the technical solution of the present application is described in detail by taking the film to be cleaned as a roll film after laser transfer in the photovoltaic industry as an example.

[0037] The surface of the film used for laser transfer has grooves. After use, silver paste is deposited on the surface of the film and in the grooves. In order to make the film recyclable for secondary use, the film needs to be ultrasonically cleaned in a cleaning tank 1 filled with a cleaning agent to clean off the silver paste on the surface of the film and in the grooves.

[0038] The present application provides a thin film cleaning tank, such as Figure 1-4 As shown, the cleaning tank body 1 is filled with cleaning agent, and an ultrasonic generating component is installed in the cleaning tank body 1. A plurality of conveying rollers 2 and a plurality of first quick-release components 3 are arranged in the cleaning tank body 1. Each of the conveying rollers 2 immersed in the cleaning agent is installed on the inner wall of the cleaning tank body 1 through the first quick-release component 3. When the conveying roller 2 immersed in the cleaning agent needs to be replaced, the conveying roller 2 immersed in the cleaning agent is removed from the inner wall of the cleaning tank body 1 through the first quick-release component 3.

[0039] Usually, the roll film to be cleaned is unwound by the unwinding mechanism, and then the film is ultrasonically cleaned in the cleaning tank 1 under the action of the conveying roller 2, and the cleaned film is conveyed to the rewinding mechanism for rewinding.

[0040] The unwinding mechanism and the rewinding mechanism are both prior art and will not be described in detail here.

[0041] During the cleaning process, the conveyor roller 2 soaked in the cleaning agent for a long time is prone to damage to its surface, resulting in damage to the film during the cleaning process, so the conveyor roller 2 needs to be replaced regularly. In the present application, the conveyor roller 2 is installed on the inner wall of the cleaning tank body 1 through the first quick-release component 3. When the conveyor roller 2 needs to be replaced, the conveyor roller 2 can be quickly removed from the inner wall of the cleaning tank body 1 through the first quick-release component 3 for replacement, thereby improving the cleaning efficiency of the film.

[0042] Further, such as Figure 5-6 As shown, a cleaning port is provided on the side wall of the cleaning trough body 1 near the bottom of the cleaning trough body 1, and a side sealing assembly 4 and a second quick-release assembly 5 for sealing the cleaning port are provided corresponding to the cleaning port. The side sealing assembly 4 is installed on the cleaning trough body 1 through the second quick-release assembly 5. When the cleaning port needs to be opened, the side sealing assembly 4 is removed from the cleaning trough body 1 through the second quick-release assembly 5.

[0043] The silver paste on the film surface and in the grooves is separated from the film under the action of the cleaning agent and ultrasound. Part of the silver paste will dissolve in the cleaning agent, and the other part of the silver paste will be deposited at the bottom of the cleaning tank 1. After a certain period of time, the silver paste deposited at the bottom of the cleaning tank 1 needs to be collected.

[0044] During the film cleaning process, the side sealing assembly 4 is installed on the side wall of the cleaning tank body 1 through the second quick-release assembly 5, so that the cleaning port is in a sealed state; when it is necessary to clean and collect the silver paste deposited at the bottom of the cleaning tank body 1, firstly, the cleaning agent in the cleaning tank body 1 is extracted through the solvent pump, and after the cleaning agent is completely extracted, the side sealing assembly 4 is removed from the side wall of the cleaning tank body 1 through the second quick-release assembly 5, so that the cleaning port is opened, and then manual or silver paste collecting devices can be inserted into the cleaning tank body 1 through the cleaning port, so as to collect the silver paste deposited at the bottom of the cleaning tank body 1, or clean the bottom of the cleaning tank body 1. The present application can quickly remove the side sealing assembly 4 from the side wall of the cleaning tank body 1, the whole process is simple to operate, and the efficiency of silver paste collection and cleaning the tank body 1 is high.

[0045] like Figure 2-4 As shown, the conveying roller 2 includes a rotating shaft 21, a rubber coating 22 and a sleeve 23, wherein the rubber coating 22 covers the outer side of the rotating shaft 21, and one end of the rotating shaft 21 passes through the sleeve 23 and is rotatably connected to the sleeve 23;

[0046] The film cleaning tank body of this embodiment also includes a mounting plate 6 and a first positioning member 7. The mounting plate 6 is mounted on the inner wall of the cleaning tank body 1. A first positioning hole is opened on the mounting plate 6. One end of the first positioning member 7 is fixedly mounted on the shaft sleeve 23, and the other end is inserted into the first positioning hole.

[0047] In this embodiment, under the action of the material receiving mechanism, the film is continuously unwound from the unwinding mechanism and then conveyed between the conveying rollers 2 in the cleaning tank 1. During the conveying process of the film, the rotating shaft 21 is driven to rotate relative to the shaft sleeve 23.

[0048] In the process of fixing the conveyor roller 2 on the inner wall of the cleaning tank 1, the first positioning member 7 is first inserted into the first positioning hole to position the position between the conveyor roller 2 and the mounting plate 6, and then the conveyor roller 2 is fixed to the mounting plate 6 through the first quick-release assembly 3.

[0049] like Figure 3 As shown, the first quick-release assembly 3 includes a first mounting seat 31 and a first quick-release clip 32. The first mounting seat 31 is mounted on the mounting plate 6. A first avoidance groove 33 is formed on the first mounting seat 31.

[0050] The first quick-release clamp 32 includes a first connecting rod 321, a second connecting rod 322 and a first movable rod 323. The first connecting rod 321 has a first connecting end 3211 and a first free end 3212. The second connecting rod 322 has a second connecting end 3221 and a first pressing end 3222. The first connecting end 3211 is movably connected to the second connecting end 3221. The first connecting end 3211 is also movably connected to the first mounting seat 31 through the first movable rod 323. The second connecting end 3221 is also movably connected to the first mounting seat 31.

[0051] When the first free end 3212 and the first pressing end 3222 are close to each other, the movable connection point between the first connecting end 3211 and the second connecting end 3221 is located in the first avoiding groove 33;

[0052] When the first free end 3212 and the first pressing end 3222 are away from each other so that the first connecting rod 321 and the second connecting rod 322 are located on the same horizontal line, the first pressing end 3222 is pressed against the shaft sleeve 23 .

[0053] When installing the conveying roller 2 on the inner wall of the cleaning tank body 1, first insert the first positioning member 7 into the first positioning hole, and then press down the first free end 3212 of the first connecting rod 321, so that the first free end 3212 and the first clamping end 3222 are separated from each other until the first connecting rod 321 and the second connecting rod 322 are located on the same horizontal line. At this time, the first clamping end 3222 is pressed on the shaft sleeve 23, thereby locking the conveying roller 2 on the inner wall of the cleaning tank body 1.

[0054] When the conveying roller 2 needs to be replaced, first lift the first free end 3212 so that the first free end 3212 and the first clamping end 3222 are close to each other until the movable connection point between the first connecting end 3211 and the second connecting end 3221 is located in the first avoidance groove 33. At this time, the conveying roller 2 and the cleaning tank body 1 are movably connected only by the first positioning member 7. The conveying roller 2 can be removed from the inner wall of the cleaning tank body 1 by separating the first positioning member 7 from the first positioning hole.

[0055] In the present application, a first avoidance groove 33 is provided on the first mounting seat 31 , so that the movement of the first connecting rod 321 and the second connecting rod 322 will not be hindered by the first mounting seat 31 .

[0056] In this embodiment, a plurality of conveyor rollers 2 are arranged in the cleaning tank body 1, and some of the conveyor rollers 2 are not immersed in the cleaning agent. Therefore, the present application can be designed as follows: the conveyor rollers 2 immersed in the cleaning agent are installed on the inner wall of the cleaning tank body 1 through the first quick-release assembly 3, and the conveyor rollers 2 not immersed in the cleaning agent are fixedly installed on the inner wall of the cleaning tank body 1 using the existing traditional method.

[0057] When only one conveying roller 2 is rotatably mounted on the shaft sleeve 23, the conveying roller 2 is fixed to the mounting plate 6 by two first quick-release clamps 32. Specifically, after the conveying roller 2 is fixed to the mounting plate 6, the first clamping ends 3222 of the two first quick-release clamps 32 are respectively located at the two ends of the shaft sleeve 23, and the conveying roller 2 is located between the two first clamping ends 3222.

[0058] When two conveying rollers 2 are rotatably mounted on the shaft sleeve 23, the conveying rollers 2 are fixed to the mounting plate 6 by a first quick release clamp 32. Specifically, when the conveying rollers 2 are fixed to the mounting plate 6, the first pressing end 3222 of the first quick release clamp 32 is located between the two conveying rollers 2.

[0059] like Figure 5-6 As shown, the side sealing assembly 4 includes a sealing plate 41 and a sealing ring 42, and the sealing ring 42 is arranged on the inner side of the sealing plate 41;

[0060] The size of the sealing plate 41 is larger than the cleaning port. When the sealing plate 41 is pressed on the cleaning tank body 1 around the cleaning port, the sealing ring 42 is pressed against the cleaning tank body 1, so that the cleaning port is in a sealed state during the cleaning process.

[0061] Furthermore, a handle 43 is installed on the outer side of the sealing plate 41 to facilitate removing the sealing portion 41 from the side wall of the cleaning tank body 1 after the second quick-release assembly 5 is released.

[0062] It can be understood that the two opposite sides of the sealing plate 41 are fixed to the cleaning tank body 1 through the second quick-release assembly 5, which can achieve a better sealing effect of the cleaning port.

[0063] Furthermore, second positioning members 8 are provided on opposite sides of the sealing plate 41 corresponding to the second quick-release assembly 5, and a second positioning hole is provided on the cleaning tank body 1. When the sealing plate 41 is pressed on the cleaning tank body 1, the second positioning member 8 is inserted into the second positioning hole.

[0064] In the process of fixing the sealing plate 41 on the side wall of the cleaning tank body 1, the second positioning member 8 is first inserted into the second positioning hole to position the position between the sealing plate 41 and the cleaning tank body 1, and then the sealing plate 41 is fixed to the cleaning tank body 1 through the second quick-release assembly 5.

[0065] Continue to refer Figure 5-6 The second quick-release assembly 5 includes a second mounting seat 51 and a second quick-release clip 52. The second mounting seat 51 is mounted on the cleaning tank body 1. A second avoidance groove 53 is formed on the second mounting seat 51.

[0066] The second quick-release clamp 52 includes a third connecting rod 521, a fourth connecting rod 522 and a second movable rod 523. The third connecting rod 521 has a third connecting end 5211 and a second free end 5212. The fourth connecting rod 522 has a fourth connecting end 5221 and a second pressing end 5222. The third connecting end 5211 is movably connected to the fourth connecting end 5221. The third connecting end 5211 is also movably connected to the second mounting seat 51 through the second movable rod 523. The fourth connecting end 5221 is also movably connected to the second mounting seat 51.

[0067] When the second free end 5212 and the second pressing end 5222 are close to each other, the movable connection point between the third connection end 5211 and the fourth connection end 5221 is located in the second avoidance groove 53;

[0068] When the second free end 5212 and the second pressing end 5222 are away from each other so that the third connecting rod 521 and the fourth connecting rod 522 are located on the same horizontal line, the second pressing end 5222 is pressed against the sealing plate 41 .

[0069] When installing the sealing plate 41 on the side wall of the cleaning tank body 1, first insert the second positioning piece 8 into the second positioning hole, and then press down the second free end 5212 of the third connecting rod 521, so that the second free end 5212 and the second clamping end 5222 are moved away from each other until the third connecting rod 521 and the fourth connecting rod 522 are located on the same horizontal line. At this time, the second clamping end 5222 is pressed on the sealing plate 41, thereby locking the sealing plate 41 on the side wall of the cleaning tank body 1.

[0070] When it is necessary to clean or collect the silver paste deposited at the bottom of the cleaning tank body 1, after the cleaning agent in the cleaning tank body 1 is completely extracted, first lift the second free end 5212 so that the second free end 5212 and the second clamping end 5222 are close to each other until the movable connection point between the third connection end 5211 and the fourth connection end 5221 is located in the second avoidance groove 53. At this time, the sealing plate 41 and the cleaning tank body 1 are movably connected only by the second positioning member 8. The second positioning member 8 can be separated from the second positioning hole to remove the sealing plate 41 from the side wall of the cleaning tank body 1, thereby opening the cleaning port for cleaning or collection.

[0071] In the present application, a second avoidance groove 53 is provided on the second mounting seat 51 , so that the movement of the third connecting rod 521 and the fourth connecting rod 522 will not be hindered by the second mounting seat 51 .
