Description

Technical Field

[0001] This utility model relates to the field of wire and cable production technology, and in particular to a wire joint detection device and a cutting device having the same. Background Technology

[0002] In the production process of wires / cables, since the length of the conductor (usually copper wire) of a single wire / cable is limited, adjacent conductors need to be connected together by a joint, and then the insulation coating is extruded to cover the conductor to ensure that the wire / cable can be made long enough.

[0003] However, these wires and cables need to have their joints removed to prevent them from affecting the conductivity of the wires and cables. Currently, there is a lack of suitable detection equipment to quickly and easily detect the location of these joints, thus affecting the efficiency of wire / cable cutting. Utility Model Content

[0013] The wire connector detection device according to the embodiment of this utility model has at least the following technical effects:

[0014] The detection device can determine the joint position of the wire by detecting changes in the magnetic field in the detection hole, which is all that is needed to guide the wire through the detection hole.

Therefore, they should not be construed as limitations on this utility model.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0028] The following is for reference. Figure 1 and Figure 2 This invention describes a wire connector detection device according to an embodiment of the present invention.

[0029] like Figure 1 and Figure 2 As shown, the wire connector detection device according to an embodiment of the present invention includes a detection device 100 and a lead wire device 200.

[0030] Reference Figure 2 , Figure 3 The detection device 100 is used to detect the joint position of the wire 400. The detection device 100 is provided with a detection hole 111. The detection device 100 contains a magnetic induction coil 120 and a receiver 121. The magnetic induction coil 120 surrounds the outside of the hole wall of the detection hole 111. The receiver 121 can detect the magnetic field change of the detection hole 111. The lead wire device 200 is used to guide the wire 400 through the detection hole 111 from front to back.

[0031] For example, such as Figure 1 and Figure 2 As shown, the detection device 100 is used to detect the location of the connector on the wire 400. The detection device 100 remains relatively stationary during the detection process. (Refer to...) Figure 2 , Figure 3The detection device 100 is provided with a detection hole 111. The detection device 100 contains a magnetic induction coil 120 and a receiver 121. The magnetic induction coil 120 surrounds the outer wall of the detection hole 111, and the receiver 121 can detect changes in the magnetic field of the detection hole 111. The magnetic induction coil 120 is used to sense the connection position of the wire 400. The lead wire device 200 is used to guide the wire 400 through the detection hole 111 from front to back.

[0032] In actual operation, the lead-lead device 200 guides the wire 400 continuously through the detection hole 111 from front to back for detection of the wire 400. Simultaneously, the magnetic induction coil 120 is energized to generate an alternating electromagnetic field. As the wire 400 continuously passes through the detection hole 111, eddy currents are formed in the conductor inside the wire 400. These eddy currents generate a secondary electromagnetic field different from the original electromagnetic field, creating an initial magnetic field change within the detection hole 111.

[0033] As the wire 400 continuously passes through the detection hole 111, the receiver 121 continuously detects the aforementioned initial magnetic field change. Since the conductor dimensions, conductivity, and other parameters of the wire 400 are relatively stable, the aforementioned initial magnetic field change is also relatively stable.

[0034] Once the connector of the wire 400 passes through the detection hole 111, a secondary magnetic field change is formed in the detection hole 111 due to the difference in conductivity between the connector and the conductor. This secondary magnetic field change is detected by the receiver 121, which is equivalent to determining the connector position of the wire 400 for subsequent processing.

[0035] In the above process, since the initial magnetic field change is relatively fixed, it is only necessary to set the detection range of the secondary magnetic field change to ensure that the detection device detects 100 connectors without detecting other impurities such as iron slag, thus avoiding misoperation.

[0036] In some embodiments of this utility model, reference is made to Figure 3 The receiver 121 is a receiving coil, which is also surrounded on the outside of the hole wall of the detection hole 111. The receiving coil senses the changes in the magnetic field in the detection hole 111.

[0037] In some embodiments of this invention, the detection device 100 further includes a circuit board 130 and a signal relay 140, with the magnetic induction coil 120 and the signal relay 140 electrically connected to the circuit board 130. After the receiver 121 detects a change in the magnetic field, it receives and judges the information through the circuit board 130. Then, the circuit board 130 controls the energization of the signal relay 140 to generate a magnetic field. The contacts of the signal relay 140 then perform a closing / opening action, effectively allowing the signal relay 140 to send a signal for control of subsequent processes.

[0038] In some embodiments of this invention, the detection device 100 further includes a battery 150, which is electrically connected to the circuit board 130. The battery 150 supplies power to the detection device 100, enabling the detection device 100 to operate without an external power source.

[0039] In some embodiments of this utility model, the detection device 100 can be connected to an external DC 9V power supply.

[0040] In some embodiments of this utility model, the detection device 100 further includes a protective shell 110. The magnetic induction coil 120, circuit board 130, and signal relay 140 are all located inside the protective shell 110. The detection hole 111 is located on the protective shell 110 and extends through both the front and rear sides of the protective shell 110. The protective shell 110 is made of nylon or acrylic material. When the wire 400 is cut or loosened, the end of the wire 400 can easily hit the detection device 100. The protective shell 110 can protect the components inside the detection device 100. Nylon and acrylic materials are strong and drop-resistant enough to be suitable as materials for the protective shell 110.

[0041] In some embodiments of this utility model, reference is made to Figure 2 The detection device 100 has a fixed bracket 160 on its lower side, a fixed rod 162 on its lower side, and a fixed groove 161 on its upper side. The detection device 100 is inserted into the fixed groove 161 on its lower side for easy fixed installation. In this way, the detection device 100 can be disassembled and replaced as needed.

[0042] In some embodiments of this invention, an elastic member 163 is provided between the fixed bracket 160 and the fixed rod 162. In this way, the elastic member 163 can act as a buffer when the detection device 100 is hit by an external force (such as an electric wire).

[0043] In some embodiments of this utility model, the elastic component 163 adopts a spring structure.

[0044] In some embodiments of this utility model, reference is made to Figure 1 The wire guiding device 200 includes a guide wheel 210 and a straightening wheel assembly 220. The guide wheel 210 is located at the front of the detection device 100, and the straightening wheel assembly 220 is located at the rear of the detection device 100. The guide wheel 210 at the front of the detection device 100 guides the wire 400 through the detection hole 111. The straightening wheel assembly 220 at the rear of the detection device 100 straightens the wire 400 after it has passed through the detection hole 111.

[0045] In some embodiments of this utility model, the straightening roller assembly 220 includes a horizontal straightening roller 221 and a vertical straightening roller 222. The axis of the horizontal straightening roller 221 extends along the left-right direction, and the axis of the vertical straightening roller 222 extends along the up-down direction. This means that the horizontal straightening roller 221 presses down on the upper and lower sides of the wire 400, and the vertical straightening roller 222 presses down on the left and right sides of the wire 400, ensuring the straightening effect of the wire 400. The axis of the horizontal straightening roller 221 extends along the left-right direction... Figure 2 The left and right directions of the detection device 100 are the same, and the vertical direction of the axis of the vertical pressure roller 222 is the same. Figure 2 The vertical direction of the detection device 100 is the same.

[0046] In some embodiments of this utility model, the lead wire device 200 further includes a tensioning wheel 230, which is used to keep the wire 400 taut during transmission and prevent the wire 400 from coming loose.

[0047] In some embodiments of this utility model, a cutting device includes the aforementioned wire joint detection device. The cutting device further includes a wire cutting device 300, which comprises a wire cutting cylinder 320 and a wire cutting blade 310. The wire cutting cylinder 320 controls the wire cutting blade 310 to move up and down, and the wire cutting blade 310 is used to cut the joint of the wire 400. Thus, after the wire joint detection device detects the joint of the wire 400, it can promptly cut it using the wire cutting blade 310.

[0048] In some embodiments of this utility model, the cutting device further includes a clamping device 330. The clamping device 330 includes an upper clamping block 331 and a lower clamping drive pulley 333. A clamping cylinder 332 is connected to the upper side of the clamping block 331, and the clamping block 331 is controlled to move up and down by the clamping cylinder 332. The clamping cylinder 332 drives the clamping block 331 to descend, and the clamping block 331, in conjunction with the clamping drive pulley 333, clamps the wire, ensuring that the wire cutter 310 cuts the wire 400 more accurately.

[0049] According to the present invention, the cutting device adopts the above-mentioned wire connector detection device, which reduces the time for the cutting device to detect the connector position, facilitates the design of a quick cutting process, and saves manpower in the detection process, thus reducing the workload.

[0050] Other configurations and operations of the cutting device according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0054] The lead wire device 200 includes a lead wire pulley 210, a straightening pulley group 220, and a tensioning pulley 230. The straightening pulley group 220 includes a horizontal straightening pulley 221 and a vertical straightening pulley 222.

[0055] The wire cutting device 300 includes a wire cutting blade 310, a wire cutting cylinder 320, and a clamping device 330. The clamping device 330 includes a clamping block 331, a clamping cylinder 332, and a clamping drive pulley 333.

[0056] According to the wire connector detection device of this utility model embodiment, by setting it up in this way, at least the following effects can be achieved: as long as the wire 400 continues to pass through the detection hole 111, the detection device 100 can determine the connector position of the wire 400 by detecting the change in the magnetic field in the detection hole 111, so as to carry out subsequent processing.
