After the strip passes through the cleaning device, the liquid removal assembly removes residual cleaning liquid from the strip surface. The strip cleaning device provided by this invention can clean base strips and other strip materials to ensure surface cleanliness.

[0027] The following is combined with Figures 1-3 This invention describes a strip cleaning device.

[0028] An embodiment of this utility model provides a strip cleaning device, including a strip guiding and conveying assembly, a lifting and cleaning assembly, and a liquid removal assembly.

[0029] The strip guiding and conveying assembly includes two sets of guide rollers, which are arranged in layers. Each set of guide rollers includes multiple guide rollers 100 spaced apart in the horizontal direction, and the guide rollers 100 in the upper layer and the guide rollers 100 in the lower layer are staggered vertically.

[0030] For example, the upper guide roller group includes two guide rollers 100, both extending in the front-to-back direction and distributed in the left-to-right direction. The lower guide roller group includes three guide rollers 100, all extending in the front-to-back direction and distributed in the left-to-right direction. The two guide roller groups together comprise five guide rollers 100, which can be arranged in an M-shape.

[0031] In addition, an inlet guide roller is provided on the upper left of the strip guide and conveyor assembly, and an outlet guide roller is provided on the upper right of the strip guide and conveyor assembly. The strip at the front end of the conveyor path extends downward and to the right from the top of the inlet guide roller to the bottom of the lower and left guide roller 100. After passing the guide roller 100, it extends upward and to the right, passing the top of the upper and left guide roller 100. Then it extends downward and to the right to the bottom of the lower and middle guide roller 100. Then it extends upward and to the right, passing the top of the upper and right guide roller 100. Then it extends downward and to the right, passing the bottom of the lower and right guide roller 100. Then it extends upward and to the right, and finally passes the top of the outlet guide roller, forming an M shape.

[0032] The lifting cleaning assembly includes a cleaner 310 and a lifting mechanism. The cleaner 310 is used to hold cleaning fluid and provide space for cleaning the strip. The lifting mechanism is used to control the cleaner 310 to move in the up and down direction.

[0033] Specifically, the cleaner 310 is located below the strip guide and conveyor assembly, and the top of the cleaner 310 is open so that the strip guide and conveyor assembly can enter the cleaner 310 when the cleaner 310 moves up and down.

[0034] The lifting mechanism is connected to the washer 310 for driving the washer 310 to move vertically to a first position or a second position. When the washer 310 moves upward to the first position, the upper guide roller 100 of the strip guiding and conveying assembly is located inside the washer 310, thus ensuring that the entire strip guiding and conveying assembly is located inside the washer 310. When the washer 310 moves downward to the second position, the lower guide roller 100 of the strip guiding and conveying assembly is located above the washer 310, thus ensuring that the entire strip guiding and conveying assembly is located outside the washer 310.

[0035] The liquid removal assembly is used to remove cleaning liquid from the surface of the strip by setting it on both sides of the downstream end of the strip. Specifically, it can be set at the upstream end of the strip near the exit guide roller.

[0036] During use, the lifting mechanism first moves the cleaner 310 downward to the second position, so that all the strip guiding and conveying components are above the cleaner 310. At this time, the strip passes around the inlet guide roller and then passes around multiple guide rollers 100 in an M shape, and finally is led out through the outlet guide roller.

[0037] Then, cleaning fluid is added into the cleaner 310. After the fluid is added, the lifting mechanism drives the cleaner 310 to move upward to the first position. During the conveying of the strip, the cleaner 310 completes the cleaning of the strip.

[0038] After the strip moves to the outside of the cleaner 310, it will pass through the liquid removal component. The liquid removal component removes the cleaning liquid from the surface of the strip and dries it before it continues to the next process.

[0039] In some embodiments, the strip cleaning device further includes a frame 200, on which the strip guiding and conveying assembly, the lifting and cleaning assembly, and the liquid removal assembly are all integrated. Thus, the strip cleaning device can be assembled as a module onto a strip processing equipment.

[0040] In some embodiments, the cleaner 310 is further provided with a cleaning fluid inlet 311 and a cleaning fluid outlet 312, both of which are equipped with valves. The cleaning fluid inlet 311 can be located near the top of the cleaner 310 and can be connected to a cleaning fluid supply device. After opening the valve, cleaning fluid can be added into the cleaner 310. The cleaning fluid outlet 312 can be located near the bottom of the cleaner 310 and can be connected to a waste liquid collection container. After opening the valve, waste liquid in the cleaner 310 can be discharged.

[0041] In some embodiments, the lifting mechanism includes a linear drive 320 and a sliding component.

[0042] The sliding assembly may include a slide rail 331 and a sliding frame 332. The slide rail 331 is mounted on the frame 200, and the sliding frame 332 is slidably connected to the slide rail 331, with the sliding direction being vertical.

[0043] The fixed part of the linear drive device 320 is connected to the frame 200, the moving end of the linear drive device 320 is connected to the sliding frame 332, and the moving direction of the moving end of the linear drive device 320 is vertical.

[0044] The cleaner 310 is mounted on the sliding frame 332. When the linear drive device 320 drives the sliding frame 332 to move, the cleaner 310 can move synchronously with the sliding frame 332.

[0045] Specifically, the aforementioned linear drive device 320 includes at least an electric actuator, a cylinder, or a lead screw and nut mechanism.

[0046] In some embodiments, the above-mentioned liquid removal assembly includes at least a pair of air knives 400. The air knives 400 are connected to the frame 200. The two air knives 400 in each pair are respectively disposed on both sides of the strip, with their air outlet plane facing the surface of the strip and cleaning towards the upstream side near the conveying direction of the strip. In this way, the cleaning liquid remaining on the strip can be blown towards the upstream side of the conveying direction of the strip and finally flow back into the cleaner 310.

[0047] In some embodiments, the cleaner 310 described above may be an ultrasonic cleaner.

[0048] The embodiments of this utility model also provide a strip processing equipment, such as a flexible photovoltaic base strip processing equipment. Since it is equipped with the strip cleaning device described above, it has the same advantages as described above, which will not be repeated here.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
