Description

Technical Field

[0001] This application relates to the field of photovoltaic cell technology, specifically to a device for treating film residue of photosensitive adhesive film for solar cells. Background Technology

[0002] In the production process of photovoltaic cells, photosensitive emulsion is an essential key material, mainly used for mask protection before electroplating copper grids. After electroplating, the photosensitive emulsion film needs to be completely removed during the film removal and etching process, which generates a large amount of film residue. This residue has a high water content and extremely strong adhesion.

[0003] Traditional membrane sludge treatment equipment uses a screw extrusion dewatering method. After membrane removal is completed in the decoction unit, the sludge is collected through a screen and preliminarily filtered. Then, a pneumatic pump draws the sludge into a dewatering machine, where the screw blades compress the sludge to achieve dewatering. However, this method has several drawbacks. First, the moisture content of the sludge after screw extrusion remains high, typically between 60% and 70%, making it highly viscous and difficult to process further. Second, the extruded sludge easily clumps together, further increasing the difficulty of transport and drying. Third, the highly viscous sludge tends to accumulate in pipelines or inside the equipment during operation, causing blockages, downtime, and increased maintenance costs. Utility Model Content

[0035] The embodiments of the present application provide a film residue treatment device for a battery piece photosensitive adhesive film, Figure 1 A schematic diagram of the film residue treatment device for a battery piece photosensitive adhesive film provided by the embodiments of the present application is shown, Figure 2 A top view of the film residue treatment device for a battery piece photosensitive adhesive film provided by the embodiments of the present application is shown, Figure 1 And Figure 2 As shown in the drawings, the film residue treatment device for a battery piece photosensitive adhesive film provided by the embodiments of the present application comprises:

[0036] A rotating cavity 100, which is connected with a rotating driving mechanism 500, so that the rotating cavity 100 can be driven to rotate by the rotating driving mechanism 500, and then the rotating cavity 100 can generate centrifugal force by rotation to make the membrane sludge in the rotating cavity 100 adhere to the cavity wall of the rotating cavity 100 under the action of centrifugal force. A transmission mechanism 200, which is arranged in the rotating cavity 100 and connected with the rotating driving mechanism 500, the transmission mechanism 200 is provided with a plurality of cutting blades 240, the cutting blades 240 are used to rotate with the transmission mechanism 200 to cut the membrane sludge in the rotating cavity 100. A microwave heating cavity 300, which is wrapped around the rotating cavity 100 and connected with a microwave generator (not shown), is used to heat the cavity wall of the rotating cavity 100 by microwave, so as to evaporate the water in the membrane sludge on the cavity wall of the rotating cavity 100. A rotating cavity cover 400 Figure 2 (not shown), which is detachably connected with the microwave heating cavity 300, is used to close the top opening of the rotating cavity 100, and the rotating cavity cover 400 is closed by being connected with the microwave heating cavity 400, which has no direct connection with the rotating cavity 100, so the rotating cavity cover 400 will not rotate with the rotating cavity 100. The rotating cavity cover 400 is provided with a feeding port 430 and an exhaust passage 410, the feeding port 430 is used to receive the membrane sludge and discharge the membrane sludge into the rotating cavity 100, and the exhaust passage 410 is used to exhaust the water vapor in the rotating cavity 100, so that the water in the membrane sludge on the cavity wall can be quickly discharged from the rotating cavity 100 after being evaporated, specifically, the exhaust passage 410 will be connected with an external exhaust device through an exhaust pipe, so as to exhaust the water vapor from the rotating cavity 100.

[0037] In some embodiments, the phototool film residue processing device provided by the embodiments of the present application is applied to remove the film residue generated by removing the photoresist in the film removal and etching process. In actual application, the film residue is continuously fed into the rotating cavity 100 through the feed port 430 provided on the rotating cavity cover 400. The rotating cavity 100 is driven by the rotating drive mechanism 500 to rotate around the axis, and a corresponding centrifugal force is generated. Under the action of the centrifugal force, part of the film residue that is not clumped moves towards the cavity wall of the rotating cavity 100 and is tightly attached to the cavity wall. There are also some film residues, such as those that are clumped due to high water content or mutual adhesion, which cannot be directly attached to the cavity wall under the action of the centrifugal force. For this kind of film residue, the transmission mechanism 200 provided in the rotating cavity 100 begins to play a key role. The transmission mechanism 200 is driven by the rotating drive mechanism 500 to rotate synchronously, and the plurality of cutting blades 240 provided thereon also rotate at high speed. These sharp and reasonably designed cutting blades 240 will accurately act on the clumped film residue and cut the clumped film residue into smaller pieces by virtue of the strong cutting force. The film residue pieces formed after cutting are also attached to the cavity wall of the rotating cavity 100 under the action of the continuous centrifugal force. The microwave heating cavity 300 is arranged around the rotating cavity 100 and connected with the microwave generator, so as to heat the cavity wall of the rotating cavity 100 by microwaves, evaporate the water in the film residue on the cavity wall of the rotating cavity 100, and finally obtain dry film residue.

[0038] The phototool film residue processing device for battery pieces provided by the present application can effectively reduce the risk of accumulation and blockage of the film residue by designing a rotating cavity and combining the centrifugal force to make the film residue be strongly attached to the cavity wall during rotation. At the same time, the planetary gear transmission mechanism and the cutting blades are provided, and the film residue in the rotating cavity is also cut and broken during rotation, further reducing the possibility of film residue adhesion. The microwave heating cavity surrounds the rotating cavity, evaporates the water in the film residue on the cavity wall by microwaves, and makes the film residue dehydrate rapidly, thereby greatly improving the processing efficiency and reducing the residual water content of the film residue, and avoiding the problem of viscous clumping.

[0039] Further, the phototool film residue processing device for battery pieces provided by the present application can further improve the dehydration efficiency of the film residue by evaporating the water vapor in the film residue through the air extraction channel.

[0040] In some embodiments, as Figure 1 and Figure 2As shown, the film residue treatment device for the battery piece photosensitive adhesive film provided by the embodiment of the present application is provided with a transmission mechanism 200, which is a planetary gear transmission mechanism and includes an epicyclic gear 210, a sun gear 220, and a plurality of planetary gears 230. The planetary gears 230 are engaged with the sun gear 220 and are arranged around the sun gear 220. The planetary gears 230 are installed on the epicyclic gear 210, and a plurality of detachable cutting blades 240 are arranged on each planetary gear 230.

[0041] The planetary gear reducer 250 is connected with the sun gear 220 through the epicyclic gear 210 at one end and connected with the rotary driving mechanism 500 at the other end. The planetary gear reducer 250 is used to control the sun gear 220 to decelerate when the transmission mechanism 200 rotates, so that the sun gear 220 and the planetary gears 230 generate a rotational differential speed. After the sun gear 220 is subjected to the deceleration treatment by the planetary gear reducer 250, the rotational speed of the sun gear 220 and the rotational speed of the planetary gears 230 in the epicyclic gear 210 generate a difference, that is, a differential speed is formed. Because the planetary gears 230 revolve around the sun gear 220 and also rotate by themselves, the cutting blades 240 are connected with the transmission components such as the planetary gears 230, and therefore the differential speed generated after the sun gear decelerates can further drive the cutting blades 240 to cut the film residue in the rotary cavity 100 according to the designed linear speed and angle, thereby improving the cutting efficiency and effect and ensuring that the film residue in the form of clumps or large pieces can be effectively cut.

[0042] It can be understood that the detailed structure of the transmission mechanism 200 is not limited further in the embodiment of the present application. As long as the transmission mechanism 200 can normally drive the cutting blades 240 to move through its rotation and make the sun gear 220 and the planetary gears 230 generate a suitable rotational differential speed in the entire film residue treatment device according to the established functional requirements, the film residue can be effectively cut, and the transmission mechanism 200 has been a well-known prior art in the mechanical engineering field. The purpose of the present application is to solve the specific problem of the film residue treatment of the battery piece photosensitive adhesive film, and not to make a new breakthrough or improvement on the transmission mechanism 200 itself.
