Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module manufacturing equipment technology, specifically to a lamination medium circulation device for a multi-layer, multi-cavity precision laminator. Background Technology
[0002] Photovoltaic modules are the core components of photovoltaic power generation systems that enable the direct conversion of light energy into electrical energy. They convert solar radiation energy into direct current electrical energy through the semiconductor photovoltaic effect. After being processed by inverters, controllers and other supporting equipment, they form electricity that can be used directly or connected to the grid. The laminator is the core equipment for photovoltaic module encapsulation. It uses high temperature and high pressure to composite materials such as solar cells, EVA film, and backsheet. During the lamination process, a heating function is required, which is usually achieved through a circulating medium.
[0003] Currently, most heat transfer media use heat transfer oil for heat transfer. During long-term high-temperature circulation, heat transfer oil is prone to producing impurities such as sludge. When these impurities enter the laminator plates of the laminator, they are prone to accumulation and blockage. In this case, the heat transfer efficiency will be reduced or even the equipment will be damaged, resulting in poor circulation effect. Utility Model Content

The heating device 2 is an electric heating tube assembly, and the heating medium is heat transfer oil. The heating tubes are made of stainless steel and have a nickel-plated surface, which is corrosion-resistant and has high thermal conductivity. It also includes: a conveying pipe 3, which connects the input end and the output end set on the lamination plate 1 and the heating device 2. The conveying pipe 3 is made of stainless steel and the pipe body is fixed by pipe clamps. It is connected to the lamination plate 1, the heating device 2 and the mounting cylinder 41 by flange sealing. A fluororubber ring is provided at the flange. A filter mechanism 4 is set on the conveying pipe 3 and is close to the heating device. At the output end of 2, when the heating device 2 is conveying the heated medium, the filtration mechanism 4 intercepts impurities in the medium; the filtration mechanism 4 includes: an installation cylinder 41, which is connected to the conveying pipe 3. The installation cylinder 41 is made of stainless steel and is welded and fixed perpendicularly to the conveying pipe 3. The weld is inspected for defects and is perpendicular to the conveying pipe 3; a filter bucket 42, which is inserted inside the installation cylinder 41. The filter bucket 42 is made of stainless steel and has a stainless steel sintered mesh at the filter opening. The filter opening of the filter bucket 42 is aligned with the conveying direction of the conveying pipe 3. When impurities are intercepted, they are located inside the filter bucket 42; and a sealing cover 43, which is threaded at the bottom end of the installation cylinder 41. The sealing cover 43 is made of stainless steel and has threads on its inner surface. It is threaded with the bottom end of the installation cylinder 41, and the sealing performance is reliable.
[0019] It also includes: a servo cylinder 5, fixedly mounted on the top of the mounting cylinder 41. The servo cylinder 5 is model EC-60 and is fixed to the top of the mounting cylinder 41 by a bracket. The bracket is made of stainless steel and welded, with high strength and good stability. The telescopic end of the servo cylinder 5 penetrates through the top surface of the mounting cylinder 41 to the inside; a cleaning disc 6, fixedly mounted on the telescopic end of the servo cylinder 5. The cleaning disc 6 is made of stainless steel and has a silicone scraper wrapped on its outer surface. The scraper fits tightly against the inner surface of the filter hopper 42, leaving no residual impurities during cleaning. The cleaning disc 6 has a threaded hole in the center and is fixed to the telescopic end of the servo cylinder 5 by bolts, making disassembly convenient. The outer surface of the cleaning disc 6 slides against the inner surface of the filter hopper 42. When the servo cylinder 5 is set to run, the cleaning disc 6 moves axially along the filter hopper 42 to push the impurities attached to the filter port of the filter hopper 42 into the filter hopper 42 for collection; and a cleaning auxiliary mechanism, set on the conveying pipe 3. The cleaning auxiliary mechanism is located on both sides of the filter mechanism 4. When the cleaning auxiliary mechanism is set to run, the medium in the area of the filter mechanism 4 in the conveying pipe 3 flows in reverse.
[0020] The cleaning auxiliary mechanism includes: a first auxiliary cylinder 7, connected to the conveying pipe 3; both the first auxiliary cylinder 7 and the second auxiliary cylinder 8 are made of stainless steel and welded to the conveying pipe 3; the weld is free of pores and cracks; the first auxiliary cylinder 7 is located on the side of the mounting cylinder 41 away from the heating device 2; the second auxiliary cylinder 8, connected to the conveying pipe 3, is located on the side of the mounting cylinder 41 closer to the heating device 2; a liquid pushing plate 10, slidably disposed inside the first auxiliary cylinder 7; a sealing plate 11, slidably disposed inside the second auxiliary cylinder 8; and a liquid pushing electric cylinder 9, fixedly disposed on the first auxiliary cylinder 7. At the top of cylinder 7, the pusher cylinder 9, model EC-40, is fixed to the top of the first auxiliary cylinder 7 via a bracket. The telescopic end of the pusher cylinder 9 is fixedly set to the surface of the pusher plate 10. When the pusher cylinder 9 is set to run, the pusher plate 10 moves downward along the first auxiliary cylinder 7, and the medium flows in the opposite direction and fills the interior of the second auxiliary cylinder 8. This ensures that when the cleaning disc 6 cleans the filter hopper 42, impurities will not clog the filter port on the filter hopper 42 due to the cleaning disc 6. Both the pusher plate 10 and the sealing plate 11 are made of stainless steel, and the outer surface is provided with an O-ring rubber ring to ensure good sealing and no medium leakage during sliding.
[0021] It also includes: a limiting ring 12, which is fixedly installed inside the first auxiliary cylinder 7 and the second auxiliary cylinder 8. The limiting ring 12 is made of stainless steel and is integrally formed with the first auxiliary cylinder 7 and the second auxiliary cylinder 8. It plays a limiting role to prevent the push plate 10 and the sealing plate 11 from moving down excessively. The limiting ring 12 is located near the lower edge of the first auxiliary cylinder 7 and the second auxiliary cylinder 8; a fixing cylinder 13, which is fixedly installed inside the second auxiliary cylinder 8. The telescopic end of the fixing cylinder 13 abuts against the surface of the sealing plate 11. The fixing cylinder 13 is a thin cylinder and is fixed to the top of the second auxiliary cylinder 8 through a bracket. The bracket is made of stainless steel and is corrosion resistant. The telescopic end of the fixing cylinder 13 is equipped with a rubber buffer pad to avoid hard collision with the sealing plate 11.
[0022] It also includes: a drain pipe 14, which is fixedly connected to the bottom of the filter bucket 42. The drain pipe 14 is made of stainless steel and is welded to the bottom of the filter bucket 42 with a good seal at the weld; a connecting pipe 15, which is connected to the bottom of the sealing cover 43. The bottom of the drain pipe 14 is inserted into the connecting pipe 15. The connecting pipe 15 is made of stainless steel and is welded to the bottom of the sealing cover 43 to ensure a reliable seal after insertion; and a sealing cap 16, which is threaded onto the bottom of the connecting pipe 15.
[0023] It also includes: a guide groove 44, which is a rectangular groove and is symmetrically opened on both sides of the outer surface of the filter bucket 42; a guide strip 45, which is fixedly set on the inner surface of the mounting cylinder 41, and the outer surface of the guide strip 45 is slidably set with the inner surface of the guide groove 44. The guide strip 45 is made of stainless steel and is fixed to the inner surface of the mounting cylinder 41 by welding to ensure that the filter bucket 42 slides axially without circumferential rotation when inserted, and the filter port is precisely aligned with the conveying direction of the conveying pipe 3.
[0024] It also includes: a pressure spring 17, which is fixedly installed inside the sealing cover 43. The pressure spring 17 is a stainless steel spring, which ensures that the top of the filter bucket 42 fits tightly with the top surface inside the mounting cylinder 41 without gaps. The other end of the pressure spring 17 abuts against the bottom end of the filter bucket 42; and a sealing ring 18, which is fixedly installed inside the sealing cover 43. The sealing ring 18 is made of fluororubber and is installed in the annular groove inside the sealing cover 43 to enhance the sealing performance between the sealing cover 43 and the mounting cylinder 41.
[0025] This utility model provides a lamination medium circulation device for a multi-layer, multi-cavity precision laminator, the specific working principle of which is as follows: Before use, install all components of the device according to the assembly requirements, ensuring that the connection of the conveying pipe 3 is firm and the seal is reliable. Inject an appropriate amount of heat transfer oil medium into the heating device 2 and the conveying pipe 3. When the laminator is started, the heating device 2 is powered on to heat the heat transfer oil. The heat transfer oil is conveyed to the laminator plate 1 through the conveying pipe 3. When it flows through the filter mechanism 4, the stainless steel sintered mesh of the filter hopper 42 intercepts sludge, metal impurities and other contaminants generated in the heat transfer oil due to high temperature, preventing impurities from flowing into the heat exchange channel of the laminator plate 1 and causing blockage, thus ensuring smooth circulation of the medium. After the filter bucket 42 has been used for a period of time, impurities will adhere to the surface of the sintered mesh at the filter port, affecting the efficiency of media flow. At this time, the cleaning procedure is started: First, the telescopic end of the fixed cylinder 13 retracts, releasing the resistance to the sealing plate 11; then, the liquid-pushing electric cylinder 9 is activated, and the telescopic end extends to push the liquid-pushing plate 10 downward along the first auxiliary cylinder 7, squeezing the media in the delivery pipe 3 to flow in the opposite direction. The media flowing in the opposite direction pushes the sealing plate 11 upward along the second auxiliary cylinder 8, filling the interior of the second auxiliary cylinder 8. At the same time, the reverse airflow washes the filter port of the filter bucket 42, loosening the attached impurities; then, the servo electric cylinder 5 is activated, and the telescopic end extends to drive the cleaning disc 6 to move downward along the axial direction of the filter bucket 42. The silicone scraper pushes the impurities attached to the filter port and the bucket wall into the interior of the filter bucket 42 for collection. Because the media flows in the opposite direction, the impurities will not clog the filter port due to the pushing of the cleaning disc 6, and the cleaning effect is more thorough. After cleaning, the retraction end of the servo cylinder 5 retracts, causing the cleaning disc 6 to reset, and the retraction end of the liquid-pushing cylinder 9 retracts, causing the liquid-pushing plate 10 to reset. The reverse-flowing medium flows back to its original conveying direction, and the extension end of the fixing cylinder 13 extends and again contacts the fixing sealing plate 11, restoring the device to normal medium circulation. When there are many impurities collected inside the filter hopper 42, the sealing cap 16 is unscrewed, and the impurities are discharged through the drain pipe 14 and the connecting pipe 15 under gravity. After discharge, the sealing cap 16 is tightened. There is no need to disassemble the filter hopper 42, making the operation convenient and efficient.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
