Description

Technical Field

[0001] The utility model relates to the technical field of solar cell production, in particular to a roller type sintering furnace impurity removal device. Background Art

[0002] With the continuous innovation and technological progress of the photovoltaic industry, the equipment in the solar cell manufacturing process is also constantly updated and developed. The sintering furnace equipment of the screen printing process is no longer monopolized by the traditional chain sintering technology, but is replaced by the sintering technology with ceramic rollers as the sintering transmission mode. The ceramic roller sintering furnace is used by many photovoltaic companies because of its strong energy consumption advantage. However, since the roller is in a positioning rotation mode, some organic residues in the cell accumulate on the roller rings at both ends of the ceramic roller for a long time to form sticky crystals, and then the grid lines at the edge of the cell are adhered, causing the grid lines to fall off, affecting the A-grade rate, and the adhered cell will appear oblique displacement, causing the sintering furnace to block the cell, affecting the production capacity and fragmentation rate.

[0003] At present, the main way to remove the adhesive on the roller ring is to stop the machine for cooling, and manually use sandpaper to polish and clean the roller ring one by one. Because the roller sintering furnace has good thermal insulation, the cooling speed is also slow, so the cooling time is longer than that of the chain sintering furnace. At the same time, the number of ceramic rollers is mostly more than 100, so the cleaning takes longer time, and the heat dissipation rate of the ceramic rollers themselves is slow. Therefore, personnel usually wear high-temperature resistant gloves for cleaning, which is inconvenient to operate and takes longer to clean, thus causing greater losses to production capacity and labor costs. At the same time, due to the fragile nature of ceramics, ceramic rollers are frequently damaged during the manual cleaning process, increasing the cost of spare parts, and manual cleaning is not thorough, and the quality of the next production is still affected to a certain extent. Based on the above reasons, it is urgent to find other cleaning methods to replace manual operations. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art to a certain extent at least. To this end, one purpose of the utility model is to provide a roller type sintering furnace impurity removal device. The device can effectively remove the adhesive on the roller ring, solve the problem of the roller or roller ring being damaged during the manual cleaning process, and the roller ring cleaning efficiency is high and the cleaning is thorough, which can significantly reduce labor costs and production costs and improve production efficiency.

[0005] In one aspect of the utility model, the utility model discloses a roller type sintering furnace impurity removal device. According to an embodiment of the utility model, the device comprises:

The cleaning plates are respectively arranged on the two side surfaces of the device body, and the cleaning plates are attached to the surfaces of the roller rings at both ends of the roller. Since the device body itself has a certain weight and the cleaning plates are attached to the surfaces of the roller rings, friction will be generated in the contact parts between the cleaning plates and the roller rings. The roller and the roller rings maintain a transmission state. Relative to the roller and the roller rings, the device body and the cleaning plates maintain a stationary state, and the contact position of the roller ring and the cleaning plate will change continuously. Under the action of the friction between the cleaning plate and the roller ring, the adhesive on the roller ring is cleaned off, thereby realizing the grinding and cleaning of the roller ring. The device does not need to be operated by artificial external force, and relies on the friction generated by its own gravity and the rotation of the roller ring to do work on the adhesive. The friction is constant, thereby avoiding damage to the roller or the roller ring, and the cleaning efficiency is high and the cleaning is thorough. Therefore, the device can effectively remove the adhesive on the roller ring, solve the problem of damage to the roller or roller ring during manual cleaning, and the roller ring cleaning efficiency is high and thorough, which can significantly reduce labor costs and production costs and improve production efficiency.

[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] In one aspect of the utility model, the utility model discloses a roller type sintering furnace impurity removal device. According to an embodiment of the utility model, referring to Figure 1-3 The device includes: a device body 100 and a cleaning plate 200.

[0031] According to the embodiment of the present utility model, referring to Figure 4 , some organic matter residues in the cell accumulate on the roller rings 20 at both ends of the roller 10 for a long time to form sticky crystals, and then the grid lines at the edge of the cell are adhered and cause the grid lines to fall off. Figure 1 and Figure 5The device body 100 is in an inverted trapezoidal shape, and the short bottom side 110 of the inverted trapezoidal structure is extended and arranged above the roller shaft 10 along the transmission direction of the roller shaft 10 perpendicular to the sintering furnace. The cleaning plates 200 are respectively arranged on the two sides of the device body 100. The cleaning plates 200 are attached to the surfaces of the roller rings 20 at both ends of the roller shaft 10. Since the device body 100 itself has a certain weight and the cleaning plates 200 are attached to the surfaces of the roller rings 20, the contact parts of the cleaning plates 200 and the roller rings 20 will generate friction, and the roller shaft 10 and the roller rings 20 maintain a transmission state. The roller ring 20, the device body 100 and the cleaning plate 200 remain stationary, and the contact position between the roller ring 20 and the cleaning plate 200 will change continuously. Under the action of the friction between the cleaning plate 200 and the roller ring 20, the adhesive on the roller ring 20 is cleaned off, thereby achieving the grinding and cleaning of the roller ring 20. The device does not require manual application of external force to operate, and relies on its own gravity and the friction generated by the rotation of the roller ring 20 to do work on the adhesive. The friction force is constant, which avoids damage to the roller 10 or the roller ring 20, and the cleaning efficiency is high and the cleaning is thorough. It should be noted that the connection method between the cleaning plate 200 and the device body 100 is a conventional method in the art, such as a threaded connection, that is, threads are respectively provided on the two side walls of the device body 100, and the sinking screws match the above threads, and then the cleaning plate 200 is fixed to the two side walls of the device body 100 by the sinking screws.

[0032] According to the embodiment of the present utility model, referring to Figure 6 The device body 100 includes a first block 130 and a second block 140 along the roller transmission direction perpendicular to the sintering furnace. The first block 130 and the second block 140 are connected by a first connecting member 30. The first block 130 and the second block 140 can be moved closer to or farther away from each other through the first connecting member 30. By dividing the device body 100 into two parts, namely the first block 130 and the second block 140, then under the action of the first connecting member 30, the first block 130 and the second block 140 can be moved closer to or farther away from each other along the roller transmission direction perpendicular to the sintering furnace. Specifically, when the roller is longer, the first block 130 and the second block 140 can be moved away from each other through the first connecting member 30. When the roller is shorter, the first block 130 and the second block 140 can be moved closer to each other through the first connecting member 30, so that the device is suitable for cleaning roller rings with different roller lengths.

[0033] According to the embodiment of the present utility model, referring to Figure 6 and Figure 7The first connecting member 30 includes a sliding block 31, which is disposed on the surface of the first block 130 and the second block 140, and the first block 130 and the second block 140 can move along the sliding block 31. Further, the first connecting member 30 also includes a sliding track 32 and a fixing assembly 33, the sliding track 32 is disposed on the sliding block 31, and the fixing assembly 33 moves along the sliding track 32 and fixes the first block 130 and the second block 140. Specifically, a thread groove (not shown) is provided on the first block 130 and the second block 140, and the fixing assembly 33 matches the thread groove (not shown). When the first block 130 and the second block 140 move to a suitable distance along the sliding block 31, the fixing assembly 33 is moved along the sliding track 32. Since the first block 130 and the second block 140 are provided with thread grooves, the fixing assembly 33 matches the thread grooves (not shown). Here, the first block 130 and the second block 140 are fixed by the interaction between the fixing assembly 33 and the thread grooves, so that the device can be applied to the cleaning of roller rings with different roller lengths. It can be understood by those skilled in the art that the position of the thread groove should be on the first block 130 and the second block 140 below the sliding track. For example, the fixing assembly 32 is a screw, and the first block 130 and the second block 140 are fixed by the tightening action of the screw and the thread groove. The distance between adjacent thread grooves or the number of thread grooves, as well as the size and number of the sliding block 31, are not particularly limited in this application, and those skilled in the art can make selections according to actual conditions.

[0034] According to the embodiment of the present utility model, referring to Figure 5 The length of the short bottom side 110 of the device body 100 is 1 cm to 2 cm longer than the length of the roller 10. The inventors found that the length of the short bottom side 110 of the device body 100 is 1 cm to 2 cm longer than the length of the roller 10, which can keep a certain distance between the short bottom side 110 of the device body 100 and the roller 10, avoiding the contact between the device body 100 and the roller 10 and causing the wear of the roller 10, and at the same time effectively removing the adhesive on the roller ring 20.

[0035] According to the embodiment of the present utility model, referring to Figure 5 The cleaning plate 200 is provided with friction lines (not shown) on one side of the surface that is attached to the roller ring 20. By providing the friction lines, the friction between the cleaning plate 200 and the roller ring 20 is increased, thereby improving the cleaning effect of the adhesive on the roller ring 20. It should be noted that the present application does not limit the size, shape, and number of the friction lines. On the premise of ensuring the cleaning effect and the life of the roller ring 20, those skilled in the art can make a selection according to actual conditions.

[0036] According to the embodiment of the present utility model, referring to Figure 7The length d of the device body 100 along the roller transmission direction is 3 to 5 roller radii. Therefore, the device is easy to put above the roller of the sintering furnace, easy to operate and can ensure cleaning efficiency.

[0037] According to the embodiment of the present utility model, referring to Figure 8 The device body 100 includes an upper block 150 and a lower block 160 along the direction from the long bottom side 120 to the short bottom side 110. The lower block 160 is divided into a third block 170 and a fourth block 180 along the roller transmission direction perpendicular to the sintering furnace. The third block 170 and the fourth block 180 are fixedly connected by a second connecting member (not shown). The third block 170 and the fourth block 180 can be moved closer to or farther away from each other through the second connecting member (not shown). For roller rings with different inclination angles, the third block 170 and the fourth block 180 are moved closer to or farther away from each other through the second connecting member (not shown), thereby adjusting the angle of the cleaning plate 200. Specifically, when the third block 170 and the fourth block 180 are moved away from each other, the angle between the cleaning plate 200 and the horizontal plane becomes larger, and when the third block 170 and the fourth block 180 are moved closer to each other, the angle between the cleaning plate 200 and the horizontal plane becomes smaller, so that the device can be used for cleaning roller rings with different angles. It should be noted that the second connecting member is a conventional component in the art, and those skilled in the art may select it according to actual conditions. For example, the components and working principle of the second connecting member are the same as those of the first connecting member.

[0038] According to the embodiment of the present utility model, referring to Figure 7 A traction ring 300 is provided on the side wall of the device body 100 in the opposite direction of the roller transmission direction. By providing the traction ring 300, the device can be fixed by a rope. Specifically, one end of the rope is connected to the traction ring 300, and the other end of the rope is fixed to a fixing member outside the sintering furnace. In this way, when the roller and the roller ring rotate, the rope pulls the device body 100 through the traction ring 300, so the device body 100 is relatively stationary relative to the roller and the roller ring, thereby achieving the purpose of removing the adhesive on the roller ring.
