Description

Technical Field

[0001] This utility model relates to the technical field of flat wire forming equipment, and in particular to a flat wire supply and conveying device. Background Technology

[0002] With the booming development of new energy vehicles, the demand for motors is increasing. Traditional round copper wire motors were once popular due to their convenient assembly. However, with the development of technology, higher requirements are being placed on motors. As a result, flat copper wire (hereinafter referred to as flat wire) hairpin motors have emerged. Compared with the former, flat wire hairpin motors are superior to round flat wire motors in terms of power, stability, and electrical efficiency under the same volume conditions.

[0003] Currently, the main function of hair clip forming machines is to remove the paint from flat wire, bend and shape it, ultimately folding it into a fixed hair clip shape. The process of hair clip forming machines mainly includes unwinding, peeling, fixed-length cutting, and hair clip forming. The unwinding stage involves two methods: active unwinding and passive unwinding, ensuring appropriate tension to keep the flat wire straight. Traditional wire feeding devices are used to feed the flat wire into the cutting device for cutting. The wire feeding device conveys the flat wire along its extension direction. Because the wire feeding device lacks a support structure to support the flat wire, when the flat wire is too long, its middle section is easily affected by gravity and bends, causing the flat wire to bend and deform, affecting the forming effect. Utility Model Content

[0004] The purpose of this utility model is to provide a flat wire feeding and conveying device to solve the technical problem in the prior art that the flat wire conveying lacks support, resulting in the flat wire bending and deformation and poor forming effect.

[0013] In some embodiments, both the pull-down pressing assembly and the outlet pressing assembly include guide posts for guiding the lifting and lowering movement of the pressing block, and the pressing block has guide holes that cooperate with the guide posts for guidance.

[0014] In some embodiments, the cable drive includes a base, a movable seat movably mounted in the base in a first direction and connected to the cable drive, and a drive member capable of moving the movable seat.

[0022] like Figure 1 and Figure 2 As shown, the flat wire feeding and conveying device 100 provided in this embodiment includes: a wire pulling device 10 for clamping a flat wire (not shown); a wire pulling drive device 20 for driving the wire pulling device 10 to move along a first direction D1 (the direction D1 is shown in the figure, and is referred to as the first direction D1 below); a wire output device 30 for clamping the flat wire, the wire output device 30 and the wire pulling device 10 being arranged at intervals along the first direction D1; and a linkage device 40, including at least one support base 41 for supporting the flat wire and a linkage mechanism 42 disposed between the wire pulling device 10 and the wire output device 30 and causing at least one support base 41 to move together along the first direction D1 when the wire pulling device 10 moves.

[0023] The aforementioned flat wire feeding and conveying device 100 includes a wire pulling device 10 for clamping the flat wire, a wire pulling drive device 20, a wire exiting device 30 for clamping the flat wire, and a linkage device 40. The linkage device 40 includes a support base 41 disposed between the wire pulling device 10 and the wire exiting device 30 for supporting the flat wire, and a linkage mechanism 42 disposed between the wire pulling device 10 and the wire exiting device 30 for moving the support base 41 together with the flat wire in the first direction D1 when the wire pulling device 10 pulls the flat wire. In this way, by providing the support base 41 between the wire pulling device 10 and the wire exiting device 30 to support the flat wire, bending deformation during flat wire conveying can be avoided, thus ensuring the flat wire forming effect.

[0024] See Figure 1 and Figure 2 The flat wire feeding and conveying device 100 provided in this embodiment is located in the front section of the flat wire forming equipment, and is set between the straightening device (not shown) and the cutting device (not shown). The flat wire feeding and conveying device 100 is mainly used to feed the straightened flat wire into the cutting device at a predetermined length for cutting, thereby obtaining the flat wire of the predetermined length.

[0025] The flat wire feeding and conveying device 100 provided in this embodiment includes a wire pulling device 10 for clamping the flat wire, a wire pulling drive device 20, a wire exiting device 30 for clamping the flat wire, and a linkage device 40. The wire pulling device 10 and the wire exiting device 30 are arranged at intervals along a first direction D1 (the first direction D1 is parallel to the extension direction of the flat wire). The wire pulling device 10 is connected to a straightening device, and the wire exiting device 30 is connected to a wire cutting device. The wire pulling device 10 is connected to the wire pulling drive device 20 and can move along the first direction D1 under the drive of the wire pulling drive device 20. The movement of the wire exiting device 30 can be understood as follows: after the wire cutting device cuts the flat wire, the wire exiting device 30 releases its grip on the flat wire. The wire pulling device 10 clamps the flat wire and, driven by the wire pulling drive device 20, moves from the leftmost position (left end in the figure) along the first direction D1 toward the wire exiting device 30 to feed the pulled flat wire into the wire exiting device 30. After the wire pulling device 10 reaches the rightmost end (right end in the figure), the wire exiting device 30 clamps the flat wire, and the wire pulling device 10 moves to the left to reset, thereby realizing the conveying of the flat wire of the predetermined length.

[0026] See Figure 1 and Figure 2The linkage device 40 provided in this embodiment includes a support base 41 disposed between the wire pulling device 10 and the wire output device 30 for supporting the flat wire, and a linkage mechanism 42 disposed between the wire pulling device 10 and the wire output device 30 for moving the support base 41 together along the first direction D1 when the wire pulling device 10 pulls the flat wire. In this embodiment, the number of support bases 41 is not limited to two. The two support bases 41 are arranged at intervals along the first direction D1 and are both connected to the linkage mechanism 42. When the wire pulling device 10 and the wire output device 30 move relative to each other, the linkage mechanism 42 will move relatively telescopically, and drive the support bases 41 to move along the first direction D1. In this way, by setting the support base 41 between the wire pulling device 10 and the wire output device 30 to support the flat wire, the deformation caused by gravity due to the excessive length of the flat wire can be avoided, which would affect the forming effect.

[0027] See Figure 1 and Figure 2 The linkage mechanism 42 provided in this embodiment includes a first-end linkage unit 421 hinged to the pull-wire device 10, a last-end linkage unit 422 hinged to the lead-out device 30, and an intermediate linkage unit 423 hinged between the first-end linkage unit 421 and the last-end linkage unit 422. A support base 41 is disposed on the intermediate linkage unit 423. In this embodiment, a pull-wire connecting block 43 is provided on the pull-wire support frame 11 of the pull-wire device 10, which is connected to the first-end linkage unit 421 through a hinge shaft 44. A lead-out connecting block 45 is provided on the lead-out support frame of the lead-out device 30, which is connected to the last-end linkage unit 422 through a hinge shaft 44. The number of intermediate linkage units 423 is not limited to two. The two intermediate linkage units 423 correspond one-to-one with the two support bases 41. Each support base 41 is installed in the middle position of the corresponding intermediate linkage unit 423. Unit 421, two intermediate connecting rod units 423, and tail connecting rod unit 422 are connected in sequence. In this way, when the cable pulling device 10 moves relative to the cable output device 30, it will push or pull the connecting rod mechanism 42 to extend or retract. This causes relative rotation and deformation between the first connecting rod unit 421 and the intermediate connecting rod unit 423, between the two intermediate connecting rod units 423, and between the intermediate connecting rod unit 423 and the tail connecting rod unit 422, so as to drive the support base 41 that supports the deformation to move together with the cable pulling device 10 between the cable pulling device 10 and the cable output device 30.

[0028] See Figure 1 and Figure 2The first-end connecting rod unit 421 provided in this embodiment includes a first-end connecting rod 421a and a second-end connecting rod 421b, one end of which is respectively hinged to the wire pulling device 10; the tail-end connecting rod unit 422 includes a first tail-end connecting rod 422a and a second tail-end connecting rod 422b, one end of which is respectively hinged to the wire exiting device 30; the intermediate connecting rod unit 423 includes a first intermediate connecting rod 423a, a second intermediate connecting rod 423b and a rotating shaft 423c, the middle part of the first intermediate connecting rod 423a and the middle part of the second intermediate connecting rod 423b are connected by the rotating shaft 423c, and the support base 41 is installed on the end of the rotating shaft 423c; the first-end connecting rod 421a, the first intermediate connecting rod 423a and the first-end connecting rod 421a are connected in sequence, and the second-end connecting rod 421b, the second intermediate connecting rod 423b and the second-end connecting rod 421b are connected in sequence. In this embodiment, each unit consists of two connecting rods. The first-end connecting rod unit 421 includes a first-end connecting rod 421a and a second-end connecting rod 421b. One end of the first-end connecting rod 421a and one end of the second-end connecting rod 421b are connected to the pull-wire connecting block 43 via a hinge shaft 44. The other end of the first-end connecting rod 421a is connected to the first intermediate connecting rod 423a, and the other end of the second-end connecting rod 421b is connected to the second intermediate connecting rod 423b. The tail-end connecting rod unit 422 includes a first tail-end connecting rod 422a and a second tail-end connecting rod 422b. One end of the first tail-end connecting rod 422a and one end of the second tail-end connecting rod 422b are connected to the outgoing wire connecting block 45 via a hinge shaft 44. The other end of the first tail-end connecting rod 422a is connected to the first intermediate connecting rod 423a, and the other end of the second tail-end connecting rod 422b is connected to the second intermediate connecting rod 423b. Understandably, each linkage unit adopts a double linkage structure, and the linkage mechanism 42 has higher connection strength and a more stable structure.

[0029] To ensure the smooth movement of the support 41, see [reference needed]. Figure 1 and Figure 2 The linkage device 40 provided in this embodiment also includes a guide rail 46 extending along the first direction D1. The number of guide rails 46 is not limited to two, and they are located on both sides of the pull wire device 10. The support base 41 is connected to the rotation shaft 423c of the intermediate linkage unit 423 through the guide plate 47. The guide plate 47 is movably mounted on the guide rail 46 along the first direction D1 by a slider. In this way, the support base 41 moves more stably under the cooperation and sliding of the guide plate 47 and the guide rail 46.

[0030] See Figure 1 and Figure 2 In this embodiment, a wire block 48 is provided on the support base 41. The wire block 48 has a wire groove 481 for the flat wire to move and extends along the first direction D1. In this way, the flat wire can be moved by the wire groove 481 to ensure the straightness of the flat wire.

[0031] See Figures 1 to 4 The wire pulling device 10 and the wire exiting device 30 provided in this embodiment may have the same or different structures. The wire pulling device 10 includes a wire pulling support frame 11 connected to the wire pulling drive device 20, a wire pulling base plate 12 disposed on the wire pulling support frame 11 for moving the flat wire, and a wire pulling pressing assembly 13 for pressing the flat wire onto the wire pulling base plate 12; the wire exiting device 30 includes a wire exiting support frame 31, a wire exiting base plate 32 disposed on the wire exiting support frame 31 for moving the flat wire, and a wire exiting pressing assembly 33 for pressing the flat wire onto the wire exiting base plate 32. In this embodiment, the wire pulling device 10 and the wire exiting device 30 have basically the same structure. The wire pulling device 10 includes a wire pulling support frame 11, a wire pulling base plate 12, and a wire pulling down pressing assembly 13. The wire exiting device 30 includes a wire exiting support frame 31, a wire exiting base plate 32, and a wire exiting down pressing assembly 33. The wire pulling support frame 11 is connected to the wire pulling drive device 20 and can move relative to the wire exiting device 30 along the first direction D1 under the drive of the wire pulling drive device 20. The wire exiting support frame 31 is mounted on the fixed frame 50. It can be understood that the wire cutting device will exit the wire. After the flat wire on the outside of the device 30 is cut, the pulling down pressing component 13 of the pulling device 10 is activated and presses the flat wire against the pulling base plate 12, thereby fixing the flat wire on the pulling device 10. At the same time, the wire exiting device 30 is separated from the flat wire, and the pulling drive device 20 causes the pulling device 10 to move. After the pulling device 10 moves to the wire exiting device 30, the wire exit pressing component 33 is activated and presses the flat wire against the wire exiting base plate 32, thereby fixing the flat wire on the wire exiting device 30. At this time, the pulling device 10 is separated from the flat wire and resets.

[0032] See Figure 3 and Figure 4 In this embodiment, both the wire drawing substrate 12 and the wire output substrate 32 are provided with a wire guide wheel structure 14. The wire guide wheel structure 14 forms a wire guide channel to guide the movement of the flat wire.

[0033] To avoid slippage when pulling the cable, see Figures 1 to 3 In this embodiment, the number of pull-down pressing components 13 is, but not limited to, two. The two pull-down pressing components 13 are arranged at intervals along the first direction D1. In this way, by using two pull-down pressing components 13 to press down the flat wire, the phenomenon of flat wire slippage due to excessive acceleration during wire pulling can be avoided, ensuring the wire pulling and feeding effect, and ensuring the forming effect.

[0034] See Figure 3 and Figure 4In this embodiment, both the pull-down pressing assembly 13 and the outlet pressing assembly 33 include a pressing block 131 for pressing the wire and a pressing power component 132 for raising and lowering the pressing block 131. The pressing power component 132 is, but is not limited to, a cylinder. The pressing power component 132 of the pull-down pressing assembly 13 is mounted on the pull-down support frame 11, and the pressing power component 132 of the outlet pressing assembly 33 is mounted on the outlet support frame 31.

[0035] See Figure 3 and Figure 4 In this embodiment, both the pull-down pressing assembly 13 and the output pressing assembly 33 include guide posts 15 for guiding the lifting and lowering movement of the pressing block 131. The pressing block 131 is provided with guide holes (not shown) that cooperate with the guide posts 15 for guidance. The guide posts 15 of the pull-down pressing assembly 13 are mounted on the pull-down base plate 12, and the guide posts 15 of the output pressing assembly 33 are mounted on the output base plate 32. In this way, the smoothness of the movement of the pressing block 131 can be improved by the cooperation of the guide posts 15 and the guide holes, thus ensuring the pressing effect.

[0036] See Figure 1 and Figure 2 In this embodiment, the cable pulling drive device 20 includes a base 21, a movable seat 22 that is movably installed in the base 21 along the first direction D1 and connected to the cable pulling device 10, and a drive member 23 that enables the movable seat 22 to move. The cable outlet device 30 is located on one side of the base 21. The drive member 23 is, but is not limited to, a motor, and is connected to a lead screw (not shown). The movable seat 22 is mounted on the lead screw.
