[0028] See Figures 1 to 8This utility model provides a multi-line photovoltaic welding ribbon dual-station take-up mechanism, including a bracket 1 and multiple sets of take-up mechanisms arranged in the bracket 1. Each set of take-up mechanisms cooperates with the front-end tin plating mechanism to take up the wire independently. Each take-up mechanism includes a workbench 2 and a turntable 3 rotatably installed in the workbench 2. Rotatable I-beam wheels 4 are symmetrically installed on the turntable 3. The turntable 3 and the I-beam wheels 4 are driven to rotate by internal motors. The workbench 2 is provided with an adjustment mechanism on one side of the turntable 3. The adjustment mechanism is provided with a first adjustment wheel 5 that can be raised and lowered. The workbench 2 is also provided with a wire feeding wheel 6 and a wire-tapping rod 7. The turntable 3 drives the I-beam wheels 4 to move to one side of the first adjustment wheel 5. At this time, the first adjustment wheel 5 descends and drives the photovoltaic welding ribbon to the I-beam wheels 4 through the wire feeding wheel 6 and the first adjustment wheel 5. The wire-tapping rod 7 flips down and presses down on the photovoltaic welding ribbon, and then the I-beam wheels 4 rotate to take up the wire.

[0029] In some embodiments, such as Figure 2 As shown, the adjustment mechanism also includes a slide table 8, a sliding block 9, and a cable bow 10. The sliding block 9 is jacking up and down on the slide table 8, the cable bow 10 is fixed on the sliding block 9, the first adjusting wheel 5 is mounted on the cable bow 10, and a second adjusting wheel 26 is mounted on one side of the sliding block 9. Both the second adjusting wheel 26 and the first adjusting wheel 5 are driven to rise and fall by the sliding block 9. Specifically, a tensioning wheel 24 is provided between the feed wheel 6 and the adjustment mechanism to provide tension. The cable bow 10 is arc-shaped and has an arc-shaped groove 11. The first adjusting wheel 5 is adjustable and installed in the arc-shaped groove 11, and is engaged by a bolt at the other end. Positioning installation allows control of the relative position and height of the first adjusting wheel 5. Both ends of the bow 10 are equipped with connection parts 12, and a push line 13 is installed between the connection parts 12. When the bow 10 descends with the sliding block 9, the push line 13 will contact the photovoltaic welding strip guided by the first adjusting wheel 5, thereby pressing it down and pushing it closer to the take-up point of the I-beam 4. A wire-tapping cylinder 25 is installed on the workbench 2, and the wire-tapping rod 7 is flipped and installed on the wire-tapping cylinder 25. After the push line 13 is pushed in, the wire-tapping cylinder 25 drives the wire-tapping rod 7 to flip and press the photovoltaic welding strip onto one side of the I-beam 4. When the I-beam 4 rotates, the wire can be taken up.

[0030] In some embodiments, such as Figures 5-8As shown, the turntable 3 is equipped with a blade 14, and the I-beam wheel 4 can extend and retract along the turntable 3. A wire-attaching mechanism is also provided on one side of the turntable 3. The wire-attaching mechanism includes a wire-attaching wheel 15, a fixed guide frame 16, and a movable guide frame 17. The movable guide frame 17 is located on one side of the I-beam wheel 4. The wire-attaching strip 18 on the wire-attaching wheel 15 is attached to the photovoltaic welding strip of the I-beam wheel 4 via the fixed guide frame 16 and the movable guide frame 17. Specifically, the fixed guide frame 16 is equipped with a drive motor 19, and the drive gear 20 on the drive motor 19 meshes with a rack 21 on one side of the movable guide frame 17. The fixed guide frame 16 is also equipped with a lifting cylinder 22, and a cutter 23 is vertically mounted at the bottom of the lifting cylinder 22. The cutter 23 is located above the wire-attaching strip 18. The turntable 3 drives the I-beam wheel 4, which has finished taking in the wire, to move to the side of the wire-attaching mechanism. The drive motor 15... 9. The drive gear 20 pulls the rack 21, causing the movable guide frame 17 to pull out the wire-attaching tape 18 and attach it to the I-beam 4 to fix the photovoltaic welding tape. When the I-beam 4 at one station reaches the required wire length, a command is issued, and the wire take-up device at the other I-beam 4 is activated. The wire guide bow 10 starts to move and rises to a position that does not interfere with the I-beam 4. Then the turntable 3 starts to rotate clockwise, and the I-beam 4 at the two stations exchange positions. The wire passes through the wire-blocking roller, at which point the wire is tangent to the bottom diameter of the wire-blocking roller and the I-beam 4. Then the wire guide bow 10 descends to the appropriate position, and the wire-attaching rod 7 starts to move, stripping the wire to the I-beam position. After the internal wire clamp holds the wire, the rotation of the I-beam 4 pulls the wire to the cutter 23 for cutting, realizing the automatic shaft changing action.

[0031] This utility model provides a multi-line photovoltaic welding ribbon dual-station take-up mechanism. A turntable is rotatably mounted on the worktable, and the turntable is symmetrically equipped with retractable and self-rotating I-beams. It can be divided into two stations to sequentially process the take-up of the two I-beams, eliminating the need for frequent replacement of the I-beams and thus improving take-up efficiency. The worktable is equipped with an adjustment mechanism and a wire-tapping rod that match the turntable, which can automatically guide the photovoltaic welding ribbon to the other take-up wheel after the take-up of one I-beam is completed, achieving fully automated take-up.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
