Description

Technical Field

[0001] The utility model relates to the technical field of wire-taking equipment, and more specifically to a wire-taking equipment for emergency stop when a copper flat wire is broken. Background Art

[0002] Copper flat wire is a conductive material mainly made of pure copper or copper alloy. Its characteristic is that the cross section is flat. Compared with traditional round wires, due to the flat shape, copper flat wire can provide a larger contact area when connected to the contact parts, which helps to reduce contact resistance, improve conductivity, and reduce energy loss and heat generation.

[0003] After the copper flat wire is produced, it needs to be wound onto a reel. The existing wire-breaking sensing mechanism of the wire-breaking equipment needs to be installed separately, which makes the overall space occupied by the wire-breaking equipment larger. Moreover, the wire-breaking reel cannot be stopped suddenly after the wire breaks, resulting in the scattering of the copper flat wire after winding. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] refer to Figure 1-2A wire-breaking emergency stop wire-winding device for a copper flat wire 4 comprises: a wire-winding mechanism 1 for winding the copper flat wire 4; a wire-arranging mechanism 2, which is spaced apart from the wire-winding mechanism 1 and has a threading die 21 that moves back and forth, wherein a threading hole 211 is provided on the threading die 21, a receiving groove 212 is provided below the threading hole 211, and a rotating wheel 213 is installed in the receiving groove 212. The wire breakage sensing guide mechanism 5 is installed in the receiving groove 212 and is located at one or both ends of the rotating wheel 213, and elastically guides the rotating wheel 213 toward the threading hole 211; the wire breakage sensing guide mechanism 5 has a moving contact 51 installed at one end of the rotating wheel 213 and a limit contact 52 located above the moving contact 51 and spaced apart; the copper flat wire 4 is pressed on the rotating wheel 213 so that the moving contact 51 is spaced apart from the limit contact 52, and after the copper flat wire 4 is broken, the rotating wheel 213 rebounds and drives the moving contact 51 to contact the limit contact 52; the braking mechanism is installed on the wire taking-up mechanism 1, and when the moving contact 51 contacts the limit contact 52, the braking mechanism is triggered to brake the wire taking-up mechanism 1. It can be understood that the wire arrangement mechanism 2 swings the copper flat wire 4 back and forth along the axial direction of the wire taking-up mechanism 1, so that the copper flat wire 4 can be evenly taken up. The rotating wheel 213 is elastically guided along the direction of the threading hole 211. The guiding setting can adopt an axial hole guiding matching structure or a slide rail guiding matching structure. The elastic member can be installed on the guiding structure. The elastic member can adopt a spring 55, a metal spring, etc. The moving contact 51 and the limit contact 52 can be understood as a touch switch, and the start and close of the braking mechanism are realized by the contact and separation of the two. In the free state, the rotating wheel 213 is lifted up due to the elastic effect, the moving contact 51 contacts the limit contact 52, and the winding mechanism 1 is in a state of stopping rotation. When winding, the copper flat wire 4 presses down on the rotating wheel 213 due to the tension, so that the moving contact 51 is separated from the limit contact 52, the braking mechanism does not work, and then the winding mechanism 1 starts to wind up. After the copper flat wire 4 breaks, the tension is lost, and the rotating wheel 213 rebounds so that the moving contact 51 contacts the limit contact 52 again, and the braking mechanism starts to brake the winding mechanism 1.

[0026] In some embodiments, the wire-taking mechanism 1 includes a wire-taking frame 11, a wire-taking reel 12 rotatably mounted on the wire-taking frame 11, and a wire-taking driver 13 that drives the wire-taking reel 12 to rotate. Further, the braking mechanism includes: a brake disc and a brake for the brake disc. Further, the wire-arranging mechanism 2 also includes: a wire-arranging frame 22, a screw 23 rotatably mounted on the wire-arranging frame 22, a guide shaft 24 arranged parallel to the screw 23, a transmission member 25 with one end threadedly sleeved on the screw 23 and the other end slidingly sleeved on the guide shaft 24, and a wire-arranging driver 26 that drives the screw 23 to rotate; the threading mold 21 is mounted on the transmission member 25. It can be understood that the wire-taking driver 13 and the wire-arranging driver 26 can be driven by a motor directly or by a transmission member 25 such as a reducer or a transmission gear set. The brake disc can be the output end of the motor, or it can be installed on a rotating member that tightens the wire-taking reel 12. The brake is a prior art and will not be described in detail here. The screw rod 23 is driven to rotate by the wire arrangement driver 26, so that the transmission member 25 threaded on the screw rod 23 moves back and forth along the guide shaft 24. Since the threading mold 21 is installed on the transmission member 25, the copper flat wire 4 is inserted into the threading hole 211 of the threading mold 21, so the copper flat wire 4 can be reciprocated for wire arrangement.

[0027] In some embodiments, an angle bar 3 is installed on the side of the wire rack 22 away from the wire take-up mechanism 1, and the angle bar 3 is lower than the coverage of the threading hole 211. It can be understood that the copper flat wire 4 is wound on the angle bar 3 from the bottom of the angle bar 3 and then inserted into the threading hole 211. This can increase the tension of the copper flat wire 4 and also make the copper flat wire 4 have downward pressure, so that the rotating wheel 213 moves downward. The angle bar 3 can be rotatably installed, and the copper wire is wound around the angle bar 3 to drive the angle bar 3 to rotate. It can also be fixedly installed, and the copper flat wire 4 and the angle bar 3 will rub when the wire is taken up.

[0028] In some embodiments, reference Figure 2-3, the wire break sensing guide mechanism 5 also includes: a guide rod 53, a slider 54 sleeved on the guide rod 53, and a spring 55 sleeved on the guide rod 53 and located below the slider 54; the limit contact 52 is installed on the top of the guide rod 53, and the moving contact 51 is installed on the end of the slider 54 close to the limit contact 52. Further, the rotating wheel 213 includes: a rotating shaft 2131 with both ends installed on the slider 54 and a roller body 2132 rotatably sleeved on the rotating shaft 2131. It can be understood that the spring 55 has an elastic upward push effect on the slider 54, and the limit contact 52 can limit the slider 54 to prevent the slider 54 from completely slipping off the guide rod 53. The slider 54 and the moving contact 51 can also be set as one piece. When winding the wire, the copper flat wire 4 presses down the rotating wheel 213 to make the slider 54 move down along the guide rod 53 and separate from the limit contact 52. After the line is broken, the rotating wheel 213 loses pressure, and the spring 55 lifts the slider 54 to drive the moving contact 51 to move upward and contact the limit contact 52.

[0029] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
