The T-shaped slider can squeeze the telescopic spring when sliding, so that the position of the connecting block and the pulley can be automatically adjusted according to the tensioning force of the photovoltaic welding ribbon, so that the tensioning force of the photovoltaic welding ribbon can always be ensured to be in a suitable range, thereby avoiding the possibility of the photovoltaic welding ribbon being torn off. When the tensioning force of the photovoltaic welding ribbon is too small, the squeezing force of the telescopic spring will be released, thereby ensuring that the tensioning force of the photovoltaic welding ribbon is in a suitable range.

When the connecting block moves upward, the inner wall of the piston cylinder contacts the outer wall of the piston plate, and the piston plate pushes the gas in the piston cylinder, thereby squeezing the gas in the piston cylinder and blowing it onto the soft brush, so that the debris adsorbed on the soft brush after cleaning can be blown off, and the debris blown off falls into the collecting box through the collecting groove, so that the accumulation of debris can be avoided, thereby preventing excessive accumulation of debris from falling onto the pulley again, ensuring that the photovoltaic welding ribbon can move smoothly on the pulley.

[0013] A method for winding a circular photovoltaic ribbon winding device comprises the following steps:

[0014] S1: When in use, first insert the photovoltaic welding ribbon roll into the square rod one, then unscrew the threaded cover, insert the winding roller into the square rod two, put the winding roller in place and then tighten the threaded cover;

[0015] S2: Before starting the driving motor, first pass the photovoltaic welding ribbon on the photovoltaic welding ribbon roll around the pulley and wind it on the winding roller, and then start the driving motor, and the driving motor drives the second disc to rotate;

[0016] S3: When the tension of the photovoltaic welding ribbon is too large, the connecting block is squeezed, and the connecting block is squeezed, which in turn squeezes the connecting strip, thereby forcing the T-shaped slider to slide in the T-shaped slide groove and automatically adjust according to the change in tension.

[0017] The present invention has the following beneficial effects:

[0018] The present invention aims to solve the problem that when the moving block drives the photovoltaic welding ribbon to move back and forth up and down, the tensioning force of the photovoltaic welding ribbon will produce a certain change. When the tensioning force of the photovoltaic welding ribbon is too large, the connecting block is squeezed, and after the connecting block is squeezed, the connecting strip is squeezed, thereby forcing the T-shaped slider to slide in the T-shaped slide groove. The T-shaped slider can squeeze the telescopic spring when sliding, so that the positions of the connecting block and the pulley can be automatically adjusted according to the tensioning force of the photovoltaic welding ribbon, so that the tensioning force of the photovoltaic welding ribbon can always be ensured to be in a suitable range, thereby avoiding the possibility of the photovoltaic welding ribbon being torn off; when the tensioning force of the photovoltaic welding ribbon is too small, the squeezing force of the telescopic spring will be released accordingly, thereby ensuring that the tensioning force of the photovoltaic welding ribbon is in a suitable range.

[0019] When the rotating shaft 2 rotates, the present invention can drive the transmission gear 1 to rotate, and the transmission gear 1 is meshed with the transmission gear 2. After the transmission gear 1 rotates, it drives the transmission gear 2 to rotate, thereby providing power for the rotation of the reciprocating screw. After the reciprocating screw rotates, it can drive the moving block to move back and forth up and down. The moving block will produce a certain amount of shaking when moving. The stabilizing rod can position the moving block when it moves, thereby ensuring that the moving block will not shake when moving, thereby improving the stability of the moving block when moving. After the moving block completes the stable up and down movement, the photovoltaic welding strip can be more smoothly wound on the winding roller, thereby preventing the welding strip from curling or folding during the winding process.

[0020] The present invention utilizes the force of the photovoltaic welding ribbon when it is rolled up to drive the pulley to rotate. After the pulley rotates, it contacts the soft brush to clean up the fine debris that falls from the photovoltaic welding ribbon. After the fine debris is cleaned, the photovoltaic welding ribbon can be ensured to move smoothly on the pulley surface. When the connecting block moves upward, the inner wall of the piston cylinder contacts the outer wall of the piston plate, and the piston plate pushes the gas in the piston cylinder, so that the gas in the piston cylinder is squeezed and blown onto the soft brush, which can blow off the debris adsorbed on the soft brush after cleaning, and the debris blown off falls into the collection box through the collecting groove, which can avoid the accumulation of debris, thereby preventing too much debris from accumulating and falling onto the pulley again, thereby ensuring that the photovoltaic welding ribbon can move smoothly on the pulley.

[0021] The present invention utilizes the force when the connecting block moves downward. When the connecting block moves downward, the baffle contacts the contact block, thereby forcing the baffle to rotate with the supporting block as the midpoint. At this time, the reset spring is squeezed, and a gap exists between the baffle and the collection box after the baffle rotates, thereby moving the debris that falls into the collection box out of the collection box. After the debris is cleaned, the connecting block moves upward. At this time, the contact block is no longer in contact with the baffle, and the squeezing force on the reset spring is released, completing the reset of the baffle, allowing the collection box to continue to collect the debris. The debris is cleaned and collected in time, reducing the impact of the debris on the operation and maintenance of the device, which helps to extend the service life of the device.

[0040] For example 2, please refer to Figure 4 - Figure 8 The present invention is a circular photovoltaic welding tape winding device. On the basis of Example 1, the tensioning mechanism 2 also includes a transmission gear 1 204 fixedly sleeved on the outer wall of the second rotating shaft 109, a transmission gear 205 fixedly sleeved on the outer wall of the reciprocating screw rod 201, and the transmission gear 205 meshes with the transmission gear 1 204. A T-shaped slide groove 206 is provided on the side wall of the moving block 202, and a plurality of T-shaped sliders 207 are slidably connected in the T-shaped slide groove 206. A telescopic spring 208 is fixedly connected to one side of the plurality of T-shaped sliders 207 close to each other. When the moving block 202 drives the photovoltaic welding tape to reciprocate up and down, the tensioning force of the photovoltaic welding tape will produce a certain change. When the tension of the photovoltaic welding tape is When the tightening force is too large, the connecting block 210 is squeezed, and after the connecting block 210 is squeezed, the connecting strip 209 is squeezed, thereby forcing the T-shaped slider 207 to slide in the T-shaped slide groove 206.

When the tensioning force of the photovoltaic welding strip is too small, the squeezing force of the telescopic spring 208 will be released, thereby ensuring that the tensioning force of the photovoltaic welding strip is in a suitable range.

[0041] The tensioning mechanism 2 also includes a connecting strip 209 rotatably connected to the top of the T-shaped slider 207, and the connecting strip 209 is rotatably connected to a connecting block 210 on the side away from the T-shaped slider 207, and the top of the moving block 202 is fixedly connected to a rectangular plate 1 211, and a telescopic rod 212 is fixedly connected to the side wall of the rectangular plate 1 211, and the telescopic rod 212 is fixedly connected to a rectangular plate 2 213 on the side away from the rectangular plate 1 211, and the bottom of the rectangular plate 213 is fixedly connected to the connecting block 210. Under the action of the telescopic rod 212, it can be ensured that the position of the connecting block 210 is always in the center position.

[0042] The dust removal mechanism 3 also includes a piston cylinder 304 fixedly connected to the top of the connecting block 210, the inner wall of the piston cylinder 304 is slidably connected to the outer wall of the piston plate 303, and a movable groove 305 is opened in the connecting block 210. A soft brush 306 is fixedly connected to the side wall of the movable groove 305, and a plurality of pulleys 307 are rotatably connected to the inner wall of the movable groove 305. The pulley 307 is driven to rotate by utilizing the force of the photovoltaic welding ribbon when it is wound.

After cleaning the fine debris, the smooth movement of the photovoltaic welding ribbon on the surface of the pulley 307 can be ensured.

[0043] The dust removal mechanism 3 also includes a collecting groove 308 opened on the inner wall of the bottom of the movable groove 305, a collecting box 309 is fixedly connected to the bottom of the connecting block 210, and two supporting blocks 310 are fixedly connected to the bottom of the collecting box 309.

When the connecting block 210 moves upward, the piston The inner wall of the cylinder 304 contacts the outer wall of the piston plate 303, and the piston plate 303 pushes the gas in the piston cylinder 304, so that the gas in the piston cylinder 304 is squeezed and blown onto the soft brush 306, so that the debris adsorbed on the soft brush 306 after cleaning can be blown off, and the blown debris falls into the collection box 309 through the collection groove 308, so as to avoid the accumulation of debris, thereby preventing too much debris from accumulating and falling onto the pulley 307 again, ensuring that the photovoltaic welding strip can move smoothly on the pulley 307.

[0044] The winding method of the winding device comprises the following steps:

[0045] S1: When in use, first insert the photovoltaic welding ribbon roll 112 into the square rod 111, then unscrew the threaded cover 115, insert the winding roller 114 into the square rod 2 113, put the winding roller 114 in place, and then tighten the threaded cover 115;

[0046] S2: before starting the driving motor 104, the photovoltaic welding ribbon on the photovoltaic welding ribbon roll 112 is first wound around the pulley 307 and wound on the winding roller 114, and then the driving motor 104 is started, and the driving motor 104 drives the disk 2 107 to rotate;

[0047] S3: When the tension of the photovoltaic welding strip is too large, the connecting block 210 is squeezed, and the connecting block 210 squeezes the connecting strip 209 after being squeezed, thereby forcing the T-shaped slider 207 to slide in the T-shaped slide groove 206 and automatically adjust according to the change of the tension.

[0048] A specific application of this embodiment is:

[0049] When the photovoltaic welding ribbon needs to be rolled up, first insert the photovoltaic welding ribbon roll 112 into the square rod 111, then unscrew the threaded cover 115, insert the winding roller 114 into the square rod 2 113, put the winding roller 114 in place and tighten the threaded cover 115, before starting the drive motor 104, first wrap the photovoltaic welding ribbon on the photovoltaic welding ribbon roll 112 around the pulley 307 and wrap it around the winding roller 114, then start the drive motor 104, the drive motor 104 drives the disc 2 107 to rotate, and the disc 2 107 rotates and passes through the strip The strip block 108 drives the disk 106 to rotate, and the rotation of the disk 106 drives the rotation of the shaft 105. The rotation of the shaft 105 can drive the photovoltaic welding tape roll 112 to rotate. When the disk 2 107 rotates, the strip block 108 drives the disk 3 110 to rotate synchronously, providing rotation power for the shaft 2 109. The rotation of the shaft 2 109 can drive the winding roller 114 to rotate. The winding roller 114 and the photovoltaic welding tape roll 112 rotate at the same time, so that the photovoltaic welding tape can be rolled on the winding roller 114, thereby completing the winding of the photovoltaic welding tape.

[0050] When the rotating shaft 2 109 rotates, it can drive the transmission gear 1 204 to rotate, and the transmission gear 1 204 is meshed with the transmission gear 2 205. After the transmission gear 1 204 rotates, it drives the transmission gear 2 205 to rotate, thereby providing power for the rotation of the reciprocating screw 201. After the reciprocating screw 201 rotates, it can drive the moving block 202 to move back and forth up and down. The moving block 202 will produce a certain amount of shaking when moving. The stabilizing rod 203 can position the moving block 202 when it moves, thereby ensuring that the moving block 202 will not shake when moving, thereby improving the stability of the moving block 202 when moving. After the moving block 202 completes the stable up and down movement, the photovoltaic welding strip can be more smoothly wound on the winding roller 114, which can prevent the welding strip from curling or folding during the winding process.

[0051] When the moving block 202 drives the photovoltaic welding strip to move up and down, the tensioning force of the photovoltaic welding strip will produce a certain change. When the tensioning force of the photovoltaic welding strip is too large, the connecting block 210 is squeezed. After the connecting block 210 is squeezed, it squeezes the connecting strip 209, thereby forcing the T-shaped slider 207 to slide in the T-shaped slide groove 206. The T-shaped slider 207 can squeeze the telescopic spring 208 when sliding, so that the positions of the connecting block 210 and the pulley 307 can be automatically adjusted according to the tensioning force of the photovoltaic welding strip. In this way, it can always ensure that the tensioning force of the photovoltaic welding strip is in an appropriate range, thereby avoiding the possibility of the photovoltaic welding strip being torn off. When the tensioning force of the photovoltaic welding strip is too small, the squeezing force of the telescopic spring 208 will be released, thereby ensuring that the tensioning force of the photovoltaic welding strip is in an appropriate range.

[0052] The photovoltaic welding ribbon is wound up with force to drive the pulley 307 to rotate. After the pulley 307 rotates, it contacts the soft brush 306 to clean up the small debris that falls from the photovoltaic welding ribbon. After the small debris is cleaned, the photovoltaic welding ribbon can move smoothly on the surface of the pulley 307. When the connecting block 210 moves upward, the inner wall of the piston cylinder 304 contacts the outer wall of the piston plate 303, and the piston plate 303 pushes the gas in the piston cylinder 304, so that the gas in the piston cylinder 304 is squeezed and blown toward The soft brush 306 is mounted on the bristle brush 306, so that the debris adsorbed on the soft brush 306 after cleaning can be blown off, and the blown-off debris falls into the collection box 309 through the collection groove 308. When the connecting block 210 moves downward, the baffle 311 contacts the contact block 313, thereby forcing the baffle 311 to rotate with the support block 310 as the midpoint. At this time, the return spring 312 is squeezed, and there is a gap between the baffle 311 and the collection box 309 after rotation, thereby moving the debris that falls into the collection box 309 out of the collection box 309.
