It should be understood that the specific embodiments described herein are only intended to explain the present application and not to limit the present application.

[0029] With reference to Figures 1 to 4 The wire quick cutting device provided by the embodiments of the present application is mainly used for cutting the coiled wire 40 into a preset length and stripping the ends of the cut wire 40, so as to facilitate welding with the wires 40 of the front and rear lamp panels when assembling into a lamp strip.

[0030] The wire quick cutting device comprises a pay-off reel for winding and unwinding the wire 40, a wire pulling device 10 arranged opposite to the pay-off reel and used for clamping the end of the wire 40 to move and pull the wire 40, a wire pressing device 20 arranged opposite to the wire pulling device 10, a cutting assembly 30 arranged between the wire pulling device 10 and the wire pressing device 20 and used for cutting the wire 40, the cutting assembly 30 comprising a first support 31, a lower cutter assembly 32 arranged on the first support 31, and an upper cutter assembly 33 arranged opposite to the lower cutter assembly 32 and movable up and down along the first support 31, the upper cutter assembly 33 comprising an upper cutter close to one side of the pay-off reel, and a wire clamping device 34 close to one side of the wire pulling device 10, the upper cutter comprising two upper stripping cutters 331 and an upper cutting cutter 332 located between the two upper stripping cutters 331, and the cutting edge position of the upper cutting cutter 332 is lower than the cutting edge positions of the two upper stripping cutters 331.

[0031] In the embodiments, the wire 40 is wound on the pay-off reel, one end of the wire 40 is pulled out by the wire pulling device 10, and the cutting assembly 30 is located between the wire pulling device 10 and the wire pressing device 20. During cutting, the two ends of the wire 40 are fixed by the wire pulling device 10 and the wire pressing device 20 respectively. Since the cutting edge position of the upper cutting cutter 332 is lower than the cutting edge positions of the two upper stripping cutters 331, when the upper cutter assembly 33 drives the upper cutting cutter 332 and the two upper stripping cutters 331 to move downward at the same time, the upper cutting cutter 332 cuts deeper, cuts the wire 40, and the two stripping cutters strip the ends of the front wire 40 and the first end of the rear wire 40, so that the internal conductive part is exposed, facilitating subsequent welding. The above structure is simple, all automatic, high in production efficiency and low in cost.

[0032] Further, with reference to Figure 4The bottom of the upper cutting knife 332 is provided with a plurality of upper cutting knife edges, the bottom of the two upper stripping knives 331 is provided with a plurality of upper stripping knife edges, the lower cutting knife assembly 32 includes two lower stripping knives 321 and a lower cutting knife 322 located between the two lower stripping knives 321, the top of the lower cutting knife 322 is provided with a plurality of lower cutting knife edges, the top of the two lower stripping knives 321 is provided with a plurality of lower stripping knife edges, the upper cutting knife edges are arranged opposite to the lower cutting knife edges, and the upper stripping knife edges are arranged opposite to the lower stripping knife edges. In this way, the upper cutting knife edges and the lower cutting knife edges can complete the cutting action at the same time, and the upper stripping knife edges and the lower stripping knife edges can also strip the top side wall and the bottom side wall of the wire 40 respectively. Moreover, the plurality of knife edges arranged at the same time can simultaneously cut and strip a plurality of wires 40, further improving the work efficiency.

[0033] In the embodiment, the first support 31 includes two columns 311 arranged opposite to each other and a horizontal plate 312 connected to the top of the two columns 311. As can be seen from the figure, the first support 31 further includes a support platform 313 located between the two columns 311. Of course, when the entire wire rapid cutting device is placed on the workbench, the support platform can also be omitted. The first driving part 35 is vertically arranged on the horizontal plate 312, and the first driving part 35 is a pneumatic cylinder. The output end of the pneumatic cylinder penetrates through the horizontal plate 312 and is connected with the upper cutting knife assembly 33. Specifically, the upper cutting knife assembly 33 includes a connecting plate 333, an upper cutting knife 332 and two upper stripping knives 331 installed on the bottom of the connecting plate 333. The output end of the pneumatic cylinder drives the upper cutting knife 332 and the two upper stripping knives 331 to move up and down through the connecting plate 333. In order to further improve the balance of the moving process of the upper cutting knife assembly 33, a sliding guide device 36 is arranged between the two ends of the upper cutting knife assembly 33 and the two columns 311.

[0034] Specifically, the sliding guide device 36 includes a sliding rail 361 arranged on the inner side of the column 311 and a sliding block 362 arranged on the sliding rail 361, and the two ends of the upper cutting knife assembly 33 are fixedly connected with the two sliding blocks 362 respectively.

[0035] In this embodiment, the two ends of the lower cutter assembly 32 are fixed between the two vertical columns 311, that is, the lower cutter assembly 32 remains stationary during the cutting process. The wire clamping device 34 includes a lower clamping rod 341 and an upper clamping rod 342. The two ends of the lower clamping rod 341 are arranged on the side of the lower cutter assembly 32 facing the wire pulling device 10, so that the lower clamping rod 341 is also in a stationary state. The two ends of the upper clamping rod 342 are fixed on the two sliders 362 respectively, and the upper clamping rod 342 can move up and down with the sliders 362 to open or close the clamp relative to the lower clamping rod 341. That is, when the slider 362 drives the upper cutter assembly 33 to move downward to complete the cutting and stripping, the upper clamping rod 341 also moves downward under the action of the slider 362 to close the clamp with the lower clamping rod 341 to clamp the end of the cut previous section of wire 40. Since the leading end of the previous section of wire 40 is clamped by the wire pulling device 10, the cut previous section of wire 40 is fixed by the wire pulling device 10 and the wire clamping device 34.

[0036] Referring to Figure 3 In order to collect the stripped wire skin, in this embodiment, a material guiding device 50 for collecting waste is also arranged below the lower cutter assembly 32. The material guiding device 50 is arranged obliquely downward towards the wire pulling device 10. The stripped wire skin 40 slides through the material guiding device 50 and falls into the collecting device at the bottom.

[0037] In this embodiment, after the cutting and stripping action is completed, the leading end of the next section of wire 40 is pressed by the wire pressing device 20, and the trailing end is still on the wire reel. The wire pressing device 20 includes a first horizontal moving platform 21 that can move close to or away from the cutting assembly 30, and a wire pressing plate 22 arranged on the first horizontal moving platform 21. The end of the wire pressing plate 22 away from the cutting assembly 30 is provided with a wire inlet hole (not labeled in the figure) for the wire 40 to pass through. The end of the wire pressing plate 22 close to the cutting assembly 30 is provided with a wire outlet hole for the wire 40 to extend out. The end of the wire pressing plate 22 close to the cutting assembly 30 is in a tapered structure. The wire pressing plate 22 is arranged on the first horizontal moving platform 21, and the wire pressing plate 22 can move horizontally under the action of the first horizontal moving platform 21 to facilitate wire feeding to the wire pulling device 10.

[0038] In this embodiment, in order to better release the wire 40 during the cutting and stripping process, a guide wheel device 60 is arranged between the wire pressing device 20 and the wire reel. The guide wheel device 60 includes a second support 61, two roller shafts 62 arranged on the second support 61, and a plurality of upper guide wheels 63 and lower guide wheels 64 arranged on the two roller shafts 62. The upper guide wheels 63 and the lower guide wheels 64 are arranged opposite to each other, and a plurality of wires 40 are arranged between the upper guide wheels 63 and the lower guide wheels 64.

[0039] In the embodiment, the pulling device 10 comprises a second horizontal moving device 11 which can move close to or away from the cutting assembly 30, and two wire clamping plates 12 which are arranged on the second horizontal moving device 11 and can be opened and closed. Before cutting and stripping, the two wire clamping plates 12 are closed to clamp the leading end of the wire 40, and when the wire 40 needs to be taken away, the two wire clamping plates 12 are opened.

[0040] Further, in the embodiment, the transfer of the wire 40 is also automatically completed. A mechanical arm 70 is arranged beside the pulling device 10 and is used to transfer the wire 40 after cutting and stripping to the next station. When the mechanical arm 70 transfers the wire 40, the two wire clamping plates of the pulling device 10 release the leading end of the wire 40, the upper cutter assembly 33 moves upward under the action of the sliding block 362, and the wire clamping device 34 releases the trailing end of the wire 40, and the mechanical arm picks up the wire 40 to the next station.

[0041] The working process of the wire rapid cutting device in the embodiment is as follows: first, the leading end of the wire 40 (wherein the leading end has been stripped) is inserted through the wire inlet hole of the wire pressing device 20, the wire outlet hole, and the lower cutter assembly 32 and the upper wire clamping rod 342 from above to the pulling device 10, and is clamped by the two wire clamping plates 12 of the pulling device 10. At this time, the upper cutting knife edge moves downward under the action of the sliding block 362, and the upper cutting knife edge cooperates with the lower cutting knife edge to complete the cutting. The upper stripping knife edge on the left cooperates with the lower stripping knife edge to strip the trailing end of the wire 40 that has been cut off, and the upper stripping knife edge on the right cooperates with the lower stripping knife edge to strip the leading end of the wire 40. The upper cutter assembly 33 moves upward, the wire clamping device 34 releases the trailing end of the wire 40, and the two wire clamping plates 12 of the pulling device 10 also release the leading end of the wire 40. The mechanical arm 70 picks up and transfers the wire 40. The second horizontal moving device 11 of the pulling device 10 drives the two wire clamping plates 12 to move towards the cutting assembly 30. At this time, the wire pressing device 20 also moves towards the cutting assembly 30 under the action of the first horizontal moving device 21. The two wire clamping plates 12 clamp the wire 40 that protrudes from the wire pressing device 20 and move reversely under the action of the second horizontal moving device 11 to return to the original position. At this time, the cutting assembly 30 performs the next cutting action, and the above actions are repeated to continuously complete the rapid cutting and stripping of the wire 40.

[0042] In summary, the wire rapid cutting device provided by the embodiment of the application has the advantages of simple structure, realization of rapid cutting, stripping and transfer of the wire, improvement of production efficiency, and reduction of labor cost.

[0043] The above merely provides the preferred embodiments of the application and is not used to limit the application. Any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
