[0025] The following further describes the present utility model with reference to the accompanying drawings and specific embodiments.

[0026] Embodiment

[0027] As Figure 1 shown, a wire take-up mechanism for ultra-high-strength stainless steel micro-wires used in photovoltaic cell screen printing of this embodiment includes a vertical plate 1, several guide rollers 2 and a wire take-up module 3.

[0028] The vertical plate 1 is fixed at the end of the workbench, and a plurality of the guide rollers 2 are horizontally and rotatably arranged on the vertical plate 1.

[0029] In this embodiment, as Figure 2 shown, among all the guide rollers 2, the end of the guide roller closest to the wire drawing module 2 is connected with a first motor 4. The first motor 4 is located on the back of the vertical plate 1 and is used to drive the connected guide roller to rotate, playing a role in auxiliary traction.

[0030] As Figure 3 shown, the wire winding module includes a base 5, a lead screw 6, a lead screw driving motor 7, a support frame 8, a wire winding motor 9 and a spool support 10; the lead screw 6 is horizontally and rotatably arranged on the base 5; the lead screw driving motor 7 is used to drive the lead screw 6 to rotate; the support frame 8 is threadedly sleeved on the lead screw 6; the wire winding motor 9 is installed on the support frame 8, and the output shaft of the wire winding motor 9 remains horizontal; the spool support 10 is fixed on the output shaft of the wire winding motor 9 and shares the same axis with the output shaft of the wire winding motor 9.

[0031] In this embodiment, a plurality of slide rails 11 are provided on the base 5. The slide rails 11 penetrate through both ends of the base 5, and the support frame 8 is slidably arranged on the slide rails 11, playing a role in limiting and guiding, ensuring the stability of the support frame 8 when moving on the lead screw 6 and avoiding its shaking.

[0032] In this embodiment, machine tool bellows protective covers 12 are sleeved on both sides of the support frame 8 on the base 5. The machine tool bellows protective covers 12 cover the lead screw 6 and play a role in protecting the lead screw 6.

[0033] As Figure 2 shown, a tension adjusting device is provided at the lower part of the front surface of the vertical plate 1. The tension adjusting device includes a connecting rod 13, a pulley 14 and a torsion spring (not shown in the figure); one end of the connecting rod 13 is rotatably arranged at the lower part of the front surface of the vertical plate 1, and the torsion spring is sleeved at the connection between the connecting rod 13 and the vertical plate 1; the pulley 14 is rotatably arranged at the end of the connecting rod 13 far from the torsion spring; thus arranged, the stainless steel micro wire after passing through the guide roller is wound around the pulley 14 for several turns and then is drawn to the spool for wire winding; when the tension is too large, the connecting rod 13 is lifted by the stainless steel micro wire, playing a role in adjusting the tension; when the tension is too small, under the action of the torsion spring, the connecting rod 13 will move downward to the equilibrium position.

[0034] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
