[0047] As attached Figure 1 -Attached Figure 8 As shown, the present invention provides a coil cutting and separating device, comprising four rods, namely an upper left rod 1, a lower left rod 2, an upper right rod 3 and a lower right rod 4, which can be arranged in the upper left, lower left, upper right and lower right directions to form a separable rectangular assembly, with reference to Figure 3-Figure 5 It is the state of separable rectangular combination; reference Figure 1 and Figure 2 , the left upper rod 1 and the right upper rod 3 can be combined separately to form an upper assembly 22, and the left lower rod 2 and the right lower rod 4 can be combined separately to form a lower assembly 23; Figure 6 and Figure 7 , the left upper rod 1 and the left lower rod 2 can be combined separately to form a left assembly 24, and the right upper rod 3 and the right lower rod 4 can be combined separately to form a right assembly 25; Figure 8 , the left upper rod 1, the left lower rod 2, the right upper rod 3 and the right lower rod 4 can be separated into independent rods;

[0048] The detachable rectangular assembly has a total of four mating surfaces, namely a first mating surface 5 between the upper left rod 1 and the lower left rod 2, a second mating surface 6 between the upper right rod 3 and the lower right rod 4, a third mating surface 7 between the upper left rod 1 and the upper right rod 3, and a fourth mating surface 8 between the lower left rod 2 and the lower right rod 4. The four mating surfaces are all detachably matched with each other by magnetic attraction, that is, the four rods are provided with magnetic materials on the mating surfaces for magnetic detachable matching, so as to realize the combination and separation of the detachable rectangular assembly, the upper assembly 22, the lower assembly 23, the left assembly 24 and the right assembly 25. In a preferred embodiment, the magnetic attraction is achieved by a controllable electromagnet, and the electromagnet is turned on and off by a controller or a button provided on the rod, so as to greatly simplify the operation difficulty;

[0049] The left upper rod 1 and / or the right upper rod 3 are close to the third matching surface 7 and are provided with a cutter 9 facing downwards. The left lower rod 2 and / or the right lower rod 4 are close to the fourth matching surface 8 and are provided with a knife groove 10 for fitting the cutter 9. Figure 2-Figure 4 In a preferred embodiment, the cutter 9 is arranged at the lower right corner of the left upper rod 1, and steps are provided on the opposite sides of the left lower rod 2 and the right lower rod 4 to form a knife groove 10.

[0050] The coil cutting and separation device provided by the present invention can implement the following coil cutting and separation method:

[0051] S1, reference Figure 1 and Figure 2 , control the upper left rod 1 and the upper right rod 3 to be magnetically coupled on the third mating surface 7 to form an upper assembly 22; control the lower left rod 2 and the lower right rod 4 to be magnetically coupled on the fourth mating surface 8 to form a lower assembly 23;

[0052] S2, placing the upper assembly 22 and the lower assembly 23 on both sides of the coil 26 and aligning them;

[0053] S3, reference Figure 3-Figure 5 , controlling the first mating surface 5 and the second mating surface 6 of the upper assembly 22 and the lower assembly 23 to magnetically mate to form a separable rectangular assembly;

[0054] At this time, the cutter 9 is inserted into the knife groove 10 to complete the cutting of the coil 26, and the cut side of the coil 26 is fixed to the left combination 24 formed by the left upper rod 1 and the left lower rod 2, and the cut side of the coil 26 is fixed to the right combination 25 formed by the right upper rod 3 and the right lower rod 4;

[0055] In this step, on the one hand, the upper assembly 22 and the lower assembly 23 can complete the cutting and fixing of the coil 26 almost simultaneously during the magnetic attraction process, so that the original tension of the coil 26 can be basically maintained before and after cutting, so that the coil 26 maintains its original working state; on the other hand, since after cutting the coil 26, the left assembly 24 and the right assembly 25 respectively fix the two ends of the cut coil 26, and the fixing method is to limit the position along the entire width direction of the coil 26, so it will not cause the curling or folding of the coil 26, and the flatness of the entire width direction of the coil 26 can be well maintained. In addition, since the left assembly 24 and the right assembly 25 are still in the mutual magnetic attraction state (that is, the detachable rectangular assembly state) at this time, the cut coil 26 is indirectly connected to each other through the detachable rectangular assembly, which does not affect the working state of the original coil 26, and can leave enough operating time for the separation operation of the coil 26.

[0056] S4, the magnetic attraction between the third mating surface 7 and the fourth mating surface 8 is cancelled, the left assembly 24 and the right assembly 25 can be separated from each other, and the two ends of the coil 26 are processed in the next step respectively.

[0057] In this step, since the cut coil 26 is fixed by the left assembly 24 and the right assembly 25 instead of the staff holding the coil 26 at its two corners, it can be ensured that the width direction of the coil 26 can be flat during the entire movement process, avoiding damage to the coil 26.

[0058] The coil cutting and separating device provided by the present invention is suitable for coil coating equipment, coil film coating equipment, and coil production equipment. The coil 26 can be various fabrics, such as conductive fabric, electromagnetic shielding fabric, etc. The coil cutting and separating device can complete the cutting of the coil 26 while maintaining the tension in the longitudinal direction of the coil 26. The cut coils 26 are indirectly connected to each other through the separable rectangular assembly, which does not affect the working state of the original coil 26 and can leave sufficient operating time for the separation operation of the coil 26. In addition, during the separation process of the coil 26, the coil 26 is fixed by the left assembly 24 and the right assembly 25, which can ensure that the width direction of the coil 26 can be flat during the entire movement process, avoiding damage to the coil 26 and facilitating connection to the next process. At the same time, the coil 26 is cut in a straight line, which can ensure the quality of the cut portion of the coil 26, so that the cut portion of the coil 26 can be used normally and improve utilization.

[0059] In one embodiment, the first mating surface 5 and the second mating surface 6 are in the same plane after the separable rectangular assembly is assembled, that is, after the upper assembly 22 and the lower assembly 23 are mated, the first mating surface 5 and the second mating surface 6 will not be misaligned when clamping the coil 26, so that the two ends of the cut coil 26 are also in the same plane, maintaining the state of the coil 26 before cutting.

[0060] In one embodiment, the left upper rod 1 or the right upper rod 3 is provided with a first positioning ridge 11 on the side close to the third mating surface 7, and the right upper rod 3 or the left upper rod 1 is provided with a first positioning groove 12 that cooperates with the first positioning ridge 11 on the side close to the third mating surface 7. Figure 4 In a preferred embodiment, the first positioning ridge 11 is provided on the right upper rod 3, and the first positioning groove 12 is provided on the left upper rod 1;

[0061] The left lower rod 2 or the right lower rod 4 is provided with a second positioning ridge 13 on the side close to the fourth matching surface 8, and the right lower rod 4 or the left lower rod 2 is provided with a second positioning groove 14 that cooperates with the second positioning ridge 13 on the side close to the fourth matching surface 8. Figure 4 In a preferred embodiment, a second positioning ridge 13 is provided on the right lower rod 4, and a second positioning groove 14 is provided on the left lower rod 2. By providing the positioning ridge and the positioning groove, the upper left rod 1 or the upper right rod 3, and the lower left rod 2 or the lower right rod 4 can be positioned during magnetic engagement, thereby ensuring that the first engagement surface 5 and the second engagement surface 6 are in the same plane, simplifying the magnetic engagement process.

[0062] In one embodiment, the first positioning ridge 11 and the second positioning ridge 13 are trapezoidal in structure, so that the positioning boss is easy to insert into the positioning groove, and high-precision positioning can be achieved after insertion. In addition, it is also easy to separate the positioning ridge and the positioning groove to improve the coplanarity of the first mating surface 5 and the second mating surface 6.

[0063] In one embodiment, the end faces of the first positioning ridge 11 and the second positioning ridge 13 are provided with electromagnets, and the bottoms of the first positioning groove 12 and the second positioning groove 14 are provided with magnetic structures. Such a configuration can improve the magnetic attraction stability and convenience of the upper left rod 1 or the upper right rod 3, the lower left rod 2 or the lower right rod 4. The electromagnet can be used to conveniently control and cancel the magnetic attraction. The magnetic structure is preferably a magnetic material plate provided at the bottom of the groove, which can react with the electromagnet.

[0064] In one embodiment, the left upper rod 1 or the left lower rod 2 is provided with a first hinge seat 15 at one end, and the left lower rod 2 or the left upper rod 1 is provided with a first hinge rod 16. The first hinge rod 16 and the first hinge seat 15 are detachably hinged to each other. Figure 6 and Figure 8In a preferred embodiment, the first hinge seat 15 is provided on the left upper rod 1, and the first hinge rod 16 is provided on the left lower rod 2;

[0065] The upper right rod 3 and the lower right rod 4 are provided with a second hinge seat 17 at one end, and the lower right rod 4 or the upper right rod 3 is provided with a second hinge rod 18. The second hinge rod 18 and the second hinge seat 17 are detachably hinged and matched. Figure 6 and Figure 8 In a preferred embodiment, the second hinge seat 17 is provided on the upper right rod 3, and the second hinge rod 18 is provided on the lower right rod 4. In this embodiment, the upper left rod 1 or the lower left rod 2 is hinged at one end, and the lower right rod 4 or the upper right rod 3 is also hinged at the same end. When the upper left rod 1 and the upper right rod 3 are magnetically attracted, and the lower left rod 2 and the lower right rod 4 are also magnetically attracted, the upper assembly 22 and the lower assembly 23 are hinged. In this way, the alignment step of the upper assembly 22 and the lower assembly 23 can be omitted during step S2. During step S3, one end of the upper assembly 22 and the lower assembly 23 gradually move closer, so that the cutter 9 gradually cuts the coil 26 at an angle, thereby improving the success and smoothness of the cutting (similar to the principle of scissors). In addition, at this time, since the coil 26 is gradually cut from one end to the other end in the width direction of the coil 26, before it is completely cut, at least a portion of the coil 26 is in a connected state, and the other portion is fixed by the left assembly 24 and the right assembly 25, thereby ensuring the success rate of fixing the coil 26.

[0066] In one embodiment, a limiting structure is provided on the first hinge rod 16 and the first hinge seat 15, and after limiting, the upper left rod 1 and the lower left rod 2 are aligned left and right;

[0067] The second hinge rod 18 and the second hinge seat 17 are provided with a limit structure, and after the limit, the right upper rod 3 and the right lower rod 4 are aligned left and right. That is, when the hinge rod is fully inserted into the hinge seat, the third mating surface 7 and the fourth mating surface 8 are aligned, achieving magnetic attraction and positioning of the left upper rod 1 and the left lower rod 2, and the right upper rod 3 and the right lower rod 4.

[0068] In one embodiment, a first handle 19 is arranged on the first hinged rod 16 or the first hinged seat 15 along the length of the rod; a second handle 20 is arranged on the second hinged rod 18 or the second hinged seat 17 along the length of the rod. In a preferred embodiment, the first handle 19 is arranged on the first hinged rod 16, and the second handle 20 is arranged on the second hinged rod 18. The first handle 19 and the second handle 20 facilitate the operator to operate one end of the coil cutting and separating device.

[0069] A third handle 21 is arranged at the other end of the four rods along the length direction of the rods. The third handle 21 is provided to facilitate the staff to operate the other end of the coil cutting and separating device.

[0070] In one embodiment, a gasket is provided on the side of the upper left rod 1 and the lower left rod 2 close to the first mating surface 5; an electromagnet is provided on the upper left rod 1 or the lower left rod 2 close to the inner wall of the first mating surface 5, and a magnetic structure is provided on the inner wall of the lower left rod 2 or the upper left rod 1 close to the first mating surface 5.

[0071] A gasket is provided on the side of the upper right rod 3 and the lower right rod 4 near the second mating surface 6; an electromagnet is provided on the inner wall of the upper right rod 3 or the lower right rod 4 near the second mating surface 6, and a magnetic structure is provided on the inner wall of the lower right rod 4 or the upper right rod 3 near the first mating surface 5. In this embodiment, the provision of the gasket can prevent the first mating surface 5 and the second mating surface 6 from crushing the coil 26. The provision of the electromagnet facilitates the control and cancellation of magnetic attraction. The magnetic structure is preferably a magnetic material plate provided at the bottom of the groove, capable of reacting with the electromagnet.

[0074] S2, placing the upper assembly 22 and the lower assembly 23 on both sides of the coil 26 and aligning them; in the embodiment with a hinge seat and a hinge rod, the upper assembly 22 and the lower assembly 23 are aligned after the hinge seat and the hinge rod are hinged together;

[0075] S3, controlling the first mating surface 5 and the second mating surface 6 of the upper assembly 22 and the lower assembly 23 to magnetically engage with each other to form a separable rectangular assembly;

[0076] At this time, the cutter 9 is inserted into the knife groove 10 to complete the cutting of the coil 26. The cut side of the coil 26 is fixed to the left assembly 24 formed by the left upper rod 1 and the left lower rod 2, and the cut side of the coil 26 is fixed to the right assembly 25 formed by the right upper rod 3 and the right lower rod 4.
