Description

Technical Field

[0001] This invention relates to the field of string welding machine technology, specifically to a string welding machine strip feeding assembly and its usage method. Background Technology

[0002] A string welding machine is a device used for welding solar panels. It mainly consists of a ribbon feeding assembly, a welding assembly, a solar cell feeding assembly, a unloading assembly, and a control system. The ribbon feeding assembly is mainly used to supply ribbon to the string welding machine and generally has functions such as ribbon tension adjustment, ribbon cutting, and ribbon guiding.

[0003] While existing welding strip feeding assemblies for string welding machines can stably and accurately deliver welding strips to the welding assembly position of the string welding machine for welding operations, improving welding efficiency, reducing the error rate of manual operation, and ensuring the consistency of welding quality, they do not reduce the friction between the welding strip and the transmission rod during the feeding process. This may cause surface scratches, wear, or deformation of the welding strip during the feeding process, thereby affecting the conductivity and welding quality of the welding strip in later use. This reduces both the effectiveness and efficiency of the welding strip feeding assembly.

[0016] A method for using a wire feeding assembly for a string welding machine includes the following steps:

[0017] S1. When welding strip feeding is required, the welding strip is first unwound from the corresponding reel by using the controller, the first motor, the semi-circular groove, the bearing, the fixed seat, the rotating shaft, and the fixed ring. Then, one end of the welding strip is installed on the welding strip feeding assembly until one end of the welding strip passes between the outer surfaces of the two drive rollers. Next, the tension of the welding strip is adjusted by using the worktable, the controller, the second electric push rod, the U-shaped frame, and the second drive rod. Then, the tension of one end of the welding strip is moved by using the controller, the second motor, the mounting frame, and the drive rollers.

[0018] S2. Next, the concave block, lubricant, and first transmission rod are used to coat the surface of the welding strip with lubricant. Then, the rubber ring is used to scrape off almost all the lubricant from the surface of the welding strip. Finally, the remaining lubricant, the first transmission rod, the connecting block, the second transmission rod, the U-shaped frame, the second electric push rod, and the worktable are used to ensure stable feeding and transmission of the welding strip.

[0019] S3. When the welding strip with residual lubricant reaches the other groove of the double groove block, the controller, fan, four-way pipe, multi-hole pipe, water and the other groove of the double groove block are used to stir the water in the other groove of the double groove block. Then the shaking water is used to clean the residual lubricant on the surface of the welding strip. Then the two sealing rings are used to scrape away almost all the water on the surface of the welding strip.

[0020] S4. Then, by using the controller, processing box, box cover, resistance wire, temperature sensor, connecting pipe, round pipe, mounting hole and one of the grooves of the double slot block, the residual moisture on the surface of the solder strip is dried. Then, by using the controller, auxiliary board, hollow block, connecting plate, first electric push rod, fixing block and cutter, the solder strip that needs to be cut after being moved to the appropriate position is cut.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By setting up auxiliary mechanisms, the friction between the welding strip and the transmission rod during the conveying process can be reduced, thus avoiding surface scratches, wear, or deformation of the welding strip during the feeding process. This ensures the conductivity and welding quality of the welding strip in later use, improving both the performance and efficiency of the welding strip feeding assembly. When the welding strip is being fed, the surface of the welding strip can be coated with lubricant through the cooperation of the concave block, lubricant, and the first transmission rod. Then, the rubber ring can be used to scrape off almost all of the lubricant from the surface of the welding strip.

[0023] 2. By utilizing the controller, fan, four-way pipe, multi-hole pipe, water, and another groove of the double-groove block, the residual lubricant on the surface of the welding strip can be cleaned by agitating the water with gas. Then, by utilizing the cooperation of two sealing rings, almost all the clean water on the surface of the welding strip can be scraped off. After that, by utilizing the controller, processing box, box cover, resistance wire, temperature sensor, connecting pipe, round pipe, mounting hole, and one groove of the double-groove block, the residual moisture on the surface of the welding strip can be dried and removed. Then, by utilizing the cooperation of the other two sealing rings, the processed welding strip can be moved out of the interior of one groove of the double-groove block.

[0024] 3. By setting up a feeding mechanism, the welding strip can be conveyed to the welding position of the welding machine. When the welding strip feeding operation is required, the controller, the first motor, the semi-circular groove, the bearing, the fixed seat, the rotating shaft and the fixed ring are used to enable the two winding drums to unwind the welding strip simultaneously. Then, the controller, the second motor, the mounting frame and the transmission roller are used to enable the transmission and conveying operation of one end of the welding strip. Next, the connecting block and the first transmission rod are used to enable the stable feeding operation of the welding strip. At the same time, the worktable, the controller, the second electric push rod, the U-shaped frame and the second transmission rod are used to enable the tension during the welding strip feeding transmission. Finally, the controller, the auxiliary plate, the hollow block, the connecting plate, the first electric push rod, the fixed block and the cutter are used to enable the stable cutting operation of the welding strip.

Two symmetrical mounting slots 213 are opened at the bottom of the processing box 212 and the bottom of the top plate 222. A resistance wire 214 is set between the four mounting slots 213. The box cover 215 is installed on the top of the double slot block 204. A temperature sensor 216 is installed on the top of the box cover 215. A connecting pipe 217 is installed at the air outlet end of the processing box 212. Mounting holes 218 are opened on the rear surface of one of the grooves of the double slot block 204 near the top. A round tube 219 is fixedly sleeved inside one of the mounting holes 218. Two rectangular holes 220 are opened on the inner wall of one of the grooves of the double slot block 204 near the top on both sides. A sealing ring 221 is fixedly sleeved inside each rectangular hole 220.

[0039] according to Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, two of the outlets of the four-way pipe 208 are connected to the inlets of two porous pipes 210, and each outlet of the two porous pipes 210 is located inside another groove of the double-groove block 204. The other outlet of the four-way pipe 208 is connected to the inlet of the processing box 212. The detection end of the temperature sensor 216 extends into the inside of the box cover 215. The inlet of the round pipe 219 is connected to the outlet of the connecting pipe 217, so that the heated gas inside the space formed by the processing box 212 and the box cover 215 can be transported to one of the grooves of the double-groove block 204 with the cooperation of the connecting pipe 217 and the round pipe 219.

[0040] according to Figures 1-6As shown, the feeding mechanism 1 includes a workbench 101, a concave block 201 fixed inside one of the grooves of the workbench 101, a double groove block 204 fixed inside the other groove of the workbench 101, a rectangular groove 205 opened on the front surface of the workbench 101, support columns 102 fixed at the four corners of the bottom of the workbench 101, two symmetrical semi-circular grooves 103 opened near the edge of the top of the workbench 101, and two symmetrical fixed seats 105 installed near the edge of the top of the workbench 101. With the cooperation of the fixed seats 105, the semi-circular grooves 103 and the bearings, the first motor 106 can drive the rotating shaft 104 to perform stable rotation operation.

[0041] according to Figure 1 , Figure 2 and Figure 5 As shown, the shaft 104 is rotatably connected between the interior of the two semi-circular grooves 103 and the interior of the two fixed seats 105 via bearings. The first motor 106 is installed near the edge of the front surface of the worktable 101. The output end of the first motor 106 is installed with one end of the shaft 104. Two tape reel 107 are provided on the outer surface of the shaft 104. A fixing ring 108 is installed on the outer surface of the shaft 104. Three connecting blocks 109 are installed on the inner walls of the two grooves of the worktable 101. The cooperation between the connecting blocks 109 and the first transmission rod 110 ensures that no angular deviation occurs when the welding strip is fed.

[0042] according to Figure 1 , Figure 2 and Figure 5 As shown, the six connecting blocks 109 are divided into two groups. In each group, two connecting blocks 109 are rotatably connected to two first transmission rods 110. The four first transmission rods 110 are divided into two groups. One end of each first transmission rod 110 in each group moves through the surface of the other connecting block 109 in each group. The bottom of the worktable 101 moves through the U-shaped frame 111, which allows the tension of the welding strip during material feeding to be adjusted with the cooperation of the U-shaped frame 111, the second electric push rod 122, the worktable 101 and the two second transmission rods 112.

[0043] according to Figures 1-3 and Figures 5-7 As shown, two second transmission rods 112 are rotatably connected inside the U-shaped frame 111. A hollow block 113 is installed near the edge of the top of the workbench 101. Two symmetrical cylindrical holes 114 are opened on the top of the inner wall of the hollow block 113. A fixed block 116 is movably passed through the top of the inner wall of the hollow block 113. An auxiliary plate 117 is installed inside the hollow block 113. With the cooperation of the auxiliary plate 117, the hollow block 113, the first electric push rod 121, the connecting plate 115 and the cutter 119, the welding strip cutting operation can be realized.

[0044] according to Figures 1-3 and Figure 7 As shown, two symmetrical first electric push rods 121 are installed on the top of the auxiliary plate 117. The two first electric push rods 121 are respectively movably sleeved inside the two cylindrical holes 114. A connecting plate 115 is installed between the top ends of the telescopic ends of the two first electric push rods 121. The bottom of the connecting plate 115 and the top of the fixing block 116 are installed together by the first screw. This facilitates the stability of the welding strip during cutting by cooperating with the first electric push rods 121, the auxiliary plate 117, the connecting plate 115 and the fixing block 116.

[0045] according to Figures 1-3 and Figures 5-7 As shown, a limiting hole 118 is opened at the top of the hollow block 113. A cutter 119 is movably connected inside the limiting hole 118. The top of the cutter 119 and the bottom of the connecting plate 115 are installed together by a second screw. A controller 120 is installed on the rear surface of the worktable 101. A second electric push rod 122 is installed at the bottom of the worktable 101. With the cooperation of the second electric push rod 122, the U-shaped frame 111 and the worktable 101, the movement of the two second transmission rods 112 can be controlled.

[0046] according to Figures 1-3 , Figures 5-7 and Figure 9 As shown, the bottom of the inner wall of the U-shaped frame 111 is installed at the bottom of the telescopic end of the second electric push rod 122. The first motor 106, the first electric push rod 121, the second electric push rod 122, the fan 207, and the temperature sensor 216 are all electrically connected to the controller 120. Both ends of the resistance wire 214 are electrically connected to the controller 120 through wires. Two symmetrical mounting brackets 123 are installed on the top of the workbench 101. Two transmission rollers 124 are rotatably connected between the opposite sides of the two mounting brackets 123, and the two ends of each transmission roller 124 respectively move through the opposite sides of the two mounting brackets 123. A second motor 125 is installed on the surface of one of the mounting brackets 123. The output end of the second motor 125 is installed with the end of one of the transmission rollers 124 close to the second motor 125, so that one end of the welding strip can be driven by the cooperation of the second motor 125, the mounting bracket 123, and the transmission roller 124.

[0047] In this invention, when the feeding mechanism 1 is needed for feeding and conveying welding strip, firstly, two tape reels 107 containing welding strip are sequentially installed onto the rotating shaft 104. Then, the two tape reels 107 are pressed and fixed using the fixing seat 105. Next, bearings are installed at both ends of the rotating shaft 104. Then, the rotating shaft 104 is fixed by the cooperation of the two semi-circular grooves 103, the bearings, and the two fixing seats 105. After that, the output end of the first motor 106 is connected to one end of the rotating shaft 104. Then, the first motor 106 is installed on the worktable 101. Finally, one end of each of the two welding strips is manually unwound from the two tape reels 107. After one length of welding strip is unwound from each of the two tape reels 107, the... First, pass one end of each of the two welding strips through the space formed by the concave block 201 and the first connecting rod 202. Then, pass between the outer surfaces of two of the first transmission rods 110, then between the outer surfaces of two of the second transmission rods 112, then between the outer surfaces of the other two first transmission rods 110, then through the inside of the rubber ring 203. After passing through the inside of the rubber ring 203, pass between the outer surfaces of two of the second connecting rods 211 inside another groove of the double groove block 204. Then, pass through the inside of two of the sealing rings 221, and finally pass between the outer surfaces of two of the second connecting rods 211 inside one of the grooves of the double groove block 204. After completing the passing operation, pass through the other two sealing rings 221 in sequence. Between the interior of the two concave blocks and the outer surfaces of the two drive rollers 124, until one end of each welding strip rests on the top of the auxiliary plate 117, when everything is ready, the top plate 222 is installed on the top of the double groove block 204 (i.e., at the opening of one of the grooves in the double groove block 204), then lubricant is poured into the interior of the concave block 201, then the controller 120 is connected to an external power supply, then the controller 120 is turned on and the temperature threshold and operating program are set, and the heating temperature of the resistance wire 214 is set in cooperation with the temperature sensor 216, then the tension of the two welding strips is adjusted by cooperating with the U-shaped frame 111, the two second drive rods 112, the worktable 101 and the second electric push rod 122, and then the other side of the double groove block 204 is adjusted. An appropriate amount of clean water is placed inside the groove. Finally, the first motor 106, the second motor 125, the fan 207, and the resistance wire 214 are started. At this time, the second motor 125, with the cooperation of the two mounting brackets 123 and the two transmission rollers 124, directly drives one end of the two welding strips to perform transmission operation. At the same time, the first motor 106, with the cooperation of the two semi-circular grooves 103, the two fixed seats 105, the rotating shaft 104, the bearing, and the fixing ring 108, drives the two tape reels 107 to perform welding strip unwinding operation. When the two welding strips begin to perform transmission operation, the surface of each welding strip that is transmitted from inside the concave block 201 will be covered with lubricant. Then, each welding strip covered with lubricant will first pass through the inside of the rubber ring 203.When the lubricated welding strips pass through the inside of the rubber ring 203, almost all the lubricant on each welding strip is scraped off and flows back into the concave block 201. The two processed welding strips then pass between the outer surfaces of two of the first drive rods 110. As the welding strips carrying residual lubricant pass between the two first drive rods 110, the lubricant reduces the friction between the welding strips and the outer surfaces of the two first drive rods 110, thus preventing frictional damage during the welding strip feeding process. The welding strips passing between the two first drive rods 110 are then conveyed, followed by passage between the outer surfaces of two second drive rods 112, and then through the other two... Between the outer surfaces of the first transmission rod 110, the gas is then accurately guided and conveyed into the other groove of the double-groove block 204. Simultaneously, the air inlet of the activated fan 207 draws in ambient gas, which is then conveyed into the four-way pipe 208, and subsequently into the two connected porous pipes 210 and the space formed by the processing box 212 and the box cover 215. When the gas is ejected from each outlet of the two porous pipes 210, it agitates the water in the other groove of the double-groove block 204. Simultaneously, the activated resistance wire 214 rapidly heats the gas entering the aforementioned space. The heated gas is then directly conveyed into the connecting pipe 217, and subsequently into the circular... Inside pipe 219, the lubricant is then transported to one of the grooves in the double-groove block 204. When both welding strips with residual lubricant enter the other groove of the double-groove block 204, the agitated water washes away all the residual lubricant from the surfaces of the two welding strips. The lubricant-free welding strips then pass through two sealing rings 221. As they pass through these rings, the sealing rings scrape away almost all the water from their surfaces. The treated welding strips then enter one of the grooves in the double-groove block 204. When both welding strips enter one of the grooves in the double-groove block 204, this... The hot gas entering this space evaporates the residual moisture on the surfaces of the two welding strips. The moisture-laden gas is then ejected from another mounting hole 218 and discharged into the environment. The dried welding strips then enter the interiors of the other two sealing rings 221, pass between the two drive rollers 124, reach the bottom of the fixing block 116, and then move to the cutting range of the cutter 119. This method avoids friction damage to the welding strips during the feeding process. When one end of both welding strips has moved to the appropriate position and cutting is required, the controller 120 simultaneously shuts down the first motor 106 and the second motor 125, and then simultaneously starts the two first electric push rods 121.At this point, the two first electric push rods 121, in conjunction with the auxiliary plate 117 and the two cylindrical holes 114, directly drive the connecting plate 115 downwards. The downward-moving connecting plate 115 then directly moves the cutter 119 and the fixing block 116. When the bottom of the fixing block 116 contacts the tops of the two welding strips, the cutter 119 and fixing block 116 continue to move. When the cutter 119 completes cutting the two welding strips, the bottom of the fixing block 116 undergoes a certain degree of compression deformation. When both welding strips have been cut, the controller 120, in conjunction with the two first electric push rods 121, resets the cutter 119 and fixing block 116 to their initial positions.

[0048] Among them, the first motor 106, the tape reel 107, the controller 120 (PLC controller), the first electric push rod 121, the second electric push rod 122, the transmission roller 124, the second motor 125, the fan 207, the resistance wire 214 and the temperature sensor 216 are all existing technologies and will not be explained in detail here.
