For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1 The figure shows a specific embodiment of the automatic wire guiding, cutting and sucking device of the utility model, which comprises: a wire sucking body 10 for sucking and discharging waste wires, a wire cutting part 20 fixed on the wire sucking body 10, and a wire guiding part 30 spaced apart from the wire cutting part 20 in the initial state. The wire sucking body 10 has a vacuum generator 16 embedded therein, and the vacuum generator 16 is provided with a waste wire suction port 10a and a waste wire discharge port 10b; specifically, as shown in FIG. Figure 4 As shown, the vacuum generator 16 is embedded in the L-shaped wire suction body 10 through a fastener. The wire guide portion 30 includes a wire guide area 31 suitable for the wire to extend into, and the wire cutting portion 20 includes a wire cutting knife 21; the wire guide portion 30 switches from the first position to the second position under the drive of the first linear drive portion 40 and then returns to the position, and the first linear drive portion 40 is fixed on the wire suction body 10; when the wire guide portion 30 switches from the first position to the second position, the wire guide area 31 of the wire guide portion 30 approaches the wire cutting knife 21 of the wire cutting portion 20 to cut the wire, and the cut wire enters the wire suction body 10 along the waste wire suction port 10a and is discharged through the waste wire discharge port 10b.

[0027] The above-mentioned automatic wire guiding, cutting and sucking device integrates the first linear driving part 40 for controlling the movement of the wire guiding part 30, the vacuum generator 16 for sucking wires and the wire cutting part 20 on the wire sucking body 10, so that the device can realize multiple functions of wire guiding, wire cutting, wire sucking and automatic return, with a compact structure and high integration.

[0028] Specifically, Figure 2 As shown, the wire guide unit 30 includes a wire guide plate, one side of which is provided with a plurality of wire guide slots arranged along a first direction to form a wire guide area 31, and a plurality of wires extending along the longitudinal direction are respectively inserted into the wire guide slots. The first linear drive unit 40 is a cylinder, such as Figure 3As shown, the cylinder includes an inner cylinder body 41, an outer cylinder body 42, a front end cover 43, a rear end cover 44 and a piston rod 45. The front end cover 43 is connected to the inner cylinder body 41 and the outer cylinder body 42 respectively, and the rear end cover 44 is connected to the outer cylinder body 42 and has a gap with the inner cylinder body 41; the piston rod 45 extends out of the front end cover 43, and its end is fixedly connected to the wire guide part 30, and the front end cover 43 is provided with a cylinder air inlet 40a. When the gas source supplies air to the cylinder, the pressurized gas enters along the cylinder air inlet 40a on the front cover 43, causing the piston rod 45 to move toward the rodless chamber of the cylinder. The piston rod 45 drives the wire guide portion 30 to move toward the area close to the wire cutting portion 20 until the wire cutting knife 21 cuts the wire on the wire guide area 31 of the wire guide portion 30. At this time, the gas source continues to supply gas. When the gas pressure in the rodless chamber is equal to the rod chamber pressure, after the air pressure reaches instantaneous equilibrium, the piston area of ​​the rodless chamber is larger than the piston area of ​​the rod chamber. Under different thrusts, the piston rod 45 can be pushed outward, so that the wire guide portion 30 is separated from the wire cutting portion 20 until it automatically returns to the initial position, realizing a one-time wire cutting action. The first linear drive portion uses a cylinder as an actuator, and can realize the wire guiding, wire cutting, and automatic return functions only by a single gas source. No other sensors or control valves are required for control, and the control cost is low.

[0029] Specifically, in an optional implementation manner, Figure 2 As shown, the slicing unit 20 includes a slicing support plate 22, the slicing support plate 22 is fixed to the bottom surface of the slicing suction body 10, and the slicing knife 21 is fixed to the slicing support plate 22 through a connecting plate 23. More specifically, the connecting plate 23, the slicing knife 21 and the slicing support plate 22 are respectively provided with connecting holes, and the slicing knife 21 can be fixed between the connecting plate 23 and the slicing support plate 22 by fastening bolts passing through the connecting holes, and the three are simultaneously installed on the slicing suction body 10.

[0030] More specifically, if Figure 2 As shown, the wire suction body 10 is integrally formed into a polygonal block structure, the waste wire suction port 10a is located on the first vertical side of the wire suction body 10, and the wire cutting support plate 22 and a partial area of ​​the wire cutting knife 21 extend outward from the first vertical side of the wire suction body 10. More specifically, the waste wire suction port 10a is located on the upper side of the wire cutting knife 21. Since the wire is relatively light, the above arrangement is conducive to quickly sucking the wire cut by the wire cutting knife 21 into the wire suction body 10.

[0031] Specifically, in an optional embodiment, a portion of the plate surface of the wire cutting support plate 22 located in the outer area of ​​the wire suction body 10 has a notch, and a portion of the wire cutting knife 21 is located in the notch, and forms a wire cutting space suitable for cutting the wire together with the side wall of the notch. More specifically, the wire cutting knife 21 forms a triangular wire cutting space with the side wall of the notch. The blade of the wire cutting knife 21 is located on the side of the wire cutting space. The wire of the wire guiding area 31 is opposite to the wire cutting space, and when the wire guiding part 30 moves toward the wire cutting part 20, the wire of the wire guiding part 30 is quickly cut by the wire cutting knife 21.

[0032] Specifically, Figure 4 As shown, the main air inlet 10c is provided on the wire suction body 10, and the vacuum generator 16 embedded in the wire suction body 10 is provided with a vacuum generating gas path, which includes a first gas path 11 connecting the waste wire suction port 10a and the waste wire discharge port 10b and extending in a first direction, and a second gas path 12 vertically connected to the first gas path 11 and connected to the main air inlet 10c. More specifically, the first gas path 11 extends in the horizontal direction, and the second gas path 12 extends in the vertical direction, and the two form a T-shaped gas path. After the pressure gas of the gas source enters the second gas path 12 along the main air inlet 10c, a negative pressure is generated on the side of the first gas path 11 close to the waste wire suction port 10a, so that the silk thread located outside the waste wire suction port 10a is sucked in and discharged through the first gas path 11 in the vacuum generator 16 to the waste wire discharge port 10b.

[0033] In order to allow the pressurized gas from the air source to supply air to the vacuum generator 16 and the cylinder 40 through the main air inlet 10c on the wire suction body 10, the wire suction body 10 also includes a third air path 13 and a fourth air path 14 that are interconnected. The third air path 13 is used to connect the main air inlet 10c with the second air path 12, and the fourth air path 14 is used to connect the main air inlet 10c with the cylinder air inlet 40a.

[0034] Among them, Figure 4 As shown, the third gas circuit 13 includes a horizontal section and a vertical section, and the vertical section of the third gas circuit 13 extends in the same direction as the second gas circuit 12. A needle valve 15 is provided on the third gas circuit 13, and the needle valve 15 is located at the intersection of the horizontal section and the vertical section of the third gas circuit 13, and is used to adjust the air intake of the second gas circuit 12. Figure 3 As shown, the fourth air path 14 extends in the vertical direction and directly faces the cylinder air intake port 40a.

[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
