[0041] The utility model is further described below in conjunction with specific embodiments:

[0042] A wire twisting device used in a wiring device, such as Figure 2 As shown, the wiring device includes a base 1, a conveying component 2, a wire management device 4, a wire stripping device 5, and a wire twisting device 6. The conveying component 2 is fixed on the bracket 1. The conveying component 2 is provided with a plurality of toolings 3, on which the products to be processed are placed and the wires 31 on the products to be processed are positioned. The wire management device 4 is used to smooth the wires 31 exposed on the toolings 3, the wire stripping device 5 is used to strip the insulation layer outside the wires 31, and the wire twisting device 6 is used to wind the cores of the multi-strand wires 31 positioned on the toolings 3 to achieve wiring. The wire management device 4, the wire stripping device 5, and the wire twisting device 6 are sequentially arranged on the conveying component 2, and are used to drive the products to be processed through the wire management device 4, the wire stripping device 5, and the wire twisting device 6 through the conveying component 2.

[0043] like Figure 1As shown, the wire twisting device 6 includes a wire twisting frame 61, a wire twisting head 62 and a wire twisting drive assembly 63. The wire twisting frame 61 is arranged outside the turntable to support the wire twisting head 62 and the wire twisting drive assembly 63.

[0044] The wire twisting head 62 is rotatably arranged in the wire twisting machine frame 61, and a wire twisting limit opening 621 is provided in the wire twisting head 62, and the wire twisting limit opening 621 is non-circular; the wire twisting limit opening 621 has a first accommodating portion 6211 and a second accommodating portion 6212 located on both sides of the rotation center of the wire twisting head 62, and the first accommodating portion 6211 and the second accommodating portion 6212 are respectively used to accommodate part of the wire core in the wire 31; the wire twisting drive assembly 63 is arranged on the wire twisting machine frame 61, and is used to drive the wire twisting head 62 to move so that the wire core in the wire 31 is located in the first accommodating portion 6211 and the second accommodating portion 6212; when the wire twisting head 62 rotates, the inner walls of the first accommodating portion 6211 and the second accommodating portion 6212 respectively push the wire core located therein to wrap around the rotation center of the wire twisting head 62.

[0045] like Figure 3 As shown, the wire twisting drive assembly 63 in this patent includes a wire twisting slide rail 66 and a wire twisting slide plate 67 fixed on the wire twisting frame 61. The wire twisting slide plate 67 can be slidably arranged on the wire twisting slide plate 67. A motor or a cylinder driving the wire twisting slide plate 67 to slide is connected to one side of the wire twisting slide plate 67. Figure 1 , 6 As shown, the wire twisting machine frame 61 includes two vertical wire twisting support plates 611 arranged on the left and right, and a wire twisting slide rail 66 is provided on the top of the wire twisting support plate 611. The wire twisting slide plate 67 is fixed on the wire twisting slide rail 66 on the top of the wire twisting support plate 611.

[0046] The thread twisting head 62 is fixed in the thread twisting slide plate 67. Figure 3As shown, in order to save installation space, a wire twisting installation opening 671 is opened in the wire twisting slide plate 67, and the wire twisting drive assembly 63 also includes a lifting cylinder 626 arranged in the wire twisting installation opening 671, and the wire twisting head 62 installation plate is driven by the lifting cylinder 626, and the wire twisting head 62 is installed on the wire twisting head 62 installation plate. The thread twisting head 62 is cylindrical as a whole, and is connected to a thread twisting motor 625 for driving it to rotate. The thread twisting motor 625 is fixed on the mounting plate of the thread twisting head 62, and the output shaft of the thread twisting motor 625 passes through the mounting plate of the thread twisting head 62, and the thread twisting head 62 is provided on the output shaft of the thread twisting motor 625; the thread twisting head 62 mounting plate is moved to the tooling 3 where the product to be processed is installed by the thread twisting slide rail 66 and the thread twisting slide plate 67, and then the thread twisting head 62 is driven to descend and approach the tooling 3 by the lifting cylinder 626, so that the wire core of the wire 31 of the product to be processed is inserted into the thread twisting cavity 622 of the thread twisting head 62 for thread twisting.

[0047] like Figure 5 , 6 As shown, the wire twisting cavity 622 in this embodiment has a flat wire twisting limit opening 621, which is specifically rhombus-shaped, and the first accommodating portion 6211 and the second accommodating portion 6212 are formed on both sides of the rhombus; during the descending process of the wire twisting head 62, the wire core on the coil 34 and the wire core on the capacitor 35 will be located in the first accommodating portion 6211 and the second accommodating portion 6212. Due to the limited size of the entire wire twisting limit opening 621, the wire core on the coil 34 and the wire core on the capacitor 35 will not be squeezed in the first accommodating portion 6211 and the second accommodating portion 6212 at the same time. 6212, instead, part of the wire core on the coil 34 and part of the wire core on the capacitor 35 are left in the first accommodating portion 6211 and the second accommodating portion 6212 respectively, and the thread twisting head 62 is rotated under the drive of the thread twisting motor 625; since the first accommodating portion 6211 and the second accommodating portion 6212 are flat, the thread twisting head 62 will simultaneously drive the wire cores located in the first accommodating portion 6211 and the second accommodating portion 6212 to move during the rotation process, so that the wire cores are wound around the rotation center of the thread twisting head 62 to achieve a guided connection.

[0048] Therefore, the present invention only realizes the tightening of the wire 31 by rotating the wire twisting stopper 621. Compared with the existing method of clamping and rotating by the clamping claw, the tightening method in the present invention is simpler in structure, and the wire 31 is not easy to fall off from the wire twisting stopper 621, making the overall wire twisting structure more stable. The wire twisting stopper 621 can be elliptical, and the diamond shape is easy to drive the wire core to move, which is helpful for tightening the wire core.

[0049] Furthermore, the wire twisting limit opening 621 is provided with a wire twisting cavity 622 whose size gradually shrinks from the outside to the inside; Figure 6As shown, the four edges on the wire twisting limit opening 621 shrink inwards at the same time, forming a wire twisting cavity 622 on a quadrangular pyramid. After entering the wire twisting limit opening 621, the wire core shrinks toward the wire twisting cavity 622, which helps tighten the wire core.

[0050] Furthermore, one end of the thread twisting head 62 is provided with a contraction groove 623, and the center of the contraction groove 623 is provided with the thread twisting cavity 622. Figure 6 As shown, the shrinkage groove 623 is arranged at the bottom of the wire twisting head 62 , and the end of the wire core will be guided to the center by the shrinkage groove 623 after contacting with the shrinkage groove 623 , so as to better enable the wire core to enter the wire twisting limit opening 621 .

[0051] Furthermore, the wire twisting device 6 is also provided with a wire cap feeding assembly 64 and a wire cap grabbing assembly 65. The wire cap feeding assembly 64 is arranged on one side of the wire twisting frame 61 and is used to convey the wire caps to the side of the wire twisting head 62; the wire cap grabbing assembly 65 is used to grab the wire caps onto the wound wire core. Figure 1 As shown, the wire cap feeding assembly 64 includes a vibrating plate, which is connected to a feeding slide. The end of the feeding slide is provided with a wire cap loading seat close to the wire twisting head 62. The wire caps are gradually fed to the wire cap loading seat through the vibrating plate to be grabbed by the wire cap grabbing assembly 65.

[0052] The wire cap grabbing assembly 65 is specifically a manipulator, which is located in the wire twisting installation port 671 of the wire twisting support plate 611 through a lifting guide rail. The wire cap grabbing assembly 65 is synchronously driven by the wire twisting drive assembly 63, so that the wire twisting head 62 and the wire cap grabbing assembly 65 are located on the same motion trajectory. During operation, the wire twisting drive assembly 63 drives the wire twisting head 62 to twist the wire, and then the wire cap is grabbed by the wire cap grabbing assembly 65 and then directly placed on the tightened wire 31 assembly. By arranging both the wire cap grabbing assembly 65 and the wire twisting head 62 on the wire twisting drive assembly 63, the wire cap grabbing assembly 65 and the wire twisting head 62 can be operated successively only by the wire twisting drive assembly 63. If the driving structures are independently arranged, it is easy to cause the respective driving structures to interfere with each other, affecting their normal operation.

[0053] Furthermore, it also includes a wire twisting plate 68, which is used to press on the wire clamping assembly 33 to which the wire 31 is fixed. A guide bar 681 is provided on one side of the wire twisting plate 68. The guide bar 681 is used to make the wire 31 on the wire clamping assembly 33 move along the guide bar 681 to the front of the wire twisting plate 68 when the wire clamping assembly 33 moves. The wire twisting plate 68 is connected to the bottom of the wire twisting slide rail 66 by a vertical slide bar. The guide bar 681 is arc-shaped, which corresponds to the turntable in this patent. When the turntable rotates, it will drive the tooling 3 to move in an arc, so that the wire 31 on the tooling 3 moves along the guide bar 681, preventing the guide bar 681 from deviating to one side and accurately positioning it in front of the wire twisting plate 68. There are also wire twisting positioning blocks 69 before and after the wire twisting plate 68. The two front and rear wire twisting positioning blocks 69 are driven by a cylinder to squeeze each other to position the column wire 31, so as to facilitate the twisting of the wire 31.

[0054] In fact, after the wire twisting is completed, the turntable will send the tool 3 to the wire cap device 8. The wire cap device 8 has a wire cap frame 81, and the wire cap frame 81 has a wire cap pressing plate 82. There are two wire cap pressing plates 82, which are respectively located on the front and rear sides of the tool 3. They are driven by a cylinder or a motor to press the front and rear sides to press the wire caps and fix them. At the same time, the wire cap device 8 will be provided with a guide bar 681 structure similar to that in the wire twisting device 6, so that the turntable can normally send the tool 3 to the wire cap device 8.

[0055] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
