[0039] The present invention is further described below in conjunction with specific embodiments:

[0040] A wire stripping device is used in a wiring device, which 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 a bracket 1. The conveying component 2 is provided with a plurality of toolings 3, on which 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.

[0041] like Figure 1As shown, the wire stripping device 5 includes a wire stripping frame 51, a wire stripping knife group 52 and a wire stripping drive assembly 53. The wire management frame 41 is used to be fixed outside the turntable for support; the wire stripping knife group 52 is connected to a knife head drive member 521 for driving the opening and closing of the wire stripping knife group 52, and the wire stripping knife group 52 is merged onto the wire 31 through the knife head drive member 521; the wire stripping drive assembly 53 is arranged on the wire stripping frame 51, and is used to drive the wire stripping knife group 52 to the wire 31, and after the wire stripping knife group 52 is merged onto the wire 31, it drives the wire stripping knife group 52 to move to strip the insulation layer on the wire 31.

[0042] Specific as Figure 3 As shown, the wire stripping drive assembly 53 includes a first wire stripping fixed plate 531, a second wire stripping fixed plate 532 and a lifting wire stripping drive member 533. The first wire stripping fixed plate 531 and the second wire stripping fixed plate 532 are respectively arranged up and down. A support arm connected to both sides of the first wire stripping fixed plate 531 is provided on the wire stripping frame 51. In order to facilitate the structure of the first ten wire stripping drive assemblies 53, this patent hides the support arm structure in the figure. In this embodiment, a guide rail is provided at the bottom of the first wire stripping fixed plate 531, and a second wire stripping fixed plate 532 is slidably provided through the guide rail; in this patent, two guide rails are provided on the first wire stripping fixed plate 531, and are respectively horizontally arranged at both ends of the first wire stripping fixed plate 531. A slider corresponding to the guide rail is provided on the second wire stripping fixed plate 532, and the second wire stripping fixed plate 532 can slide left and right on the first wire stripping fixed plate 531 through the slider and the guide rail structure. The lifting wire stripping drive member 533 is arranged on the second wire stripping fixed plate 532, as shown in FIG. Figure 3 As shown, the lifting wire stripping drive member 533 is a cylinder fixed on the second wire stripping fixing plate 532, the cylinder is vertically arranged, and its piston is arranged downwardly for extending downwardly; at the same time, guide sleeves are arranged on both sides of the cylinder, and guide rods arranged downwardly are arranged in the guide sleeves, and the guide rods and the pistons of the cylinder are simultaneously connected to the wire stripping knife group 52 located below the second wire stripping fixing plate 532. The first wire stripping fixing plate 531 and the second wire stripping fixing plate 532 arranged up and down can effectively simplify the overall frame structure, and a clearance hole 5311 is opened on the first wire stripping plate, and the lifting wire stripping drive member 533 is fixed above the second wire stripping plate and passes through the clearance hole 5311, so that the overall structure is more compact.

[0043] The wire stripping knife set 52 is used to strip the insulation layer outside the wire 31, and the wire stripping knife set 52 is connected to a knife head driving member 521 for driving the opening and closing of the wire stripping knife set 52. Figure 3As shown, the cutter head driving member 521 is connected to the cylinder on the second wire stripping fixing plate 532, and the cutter head driving member 521 includes a module base plate 5211 connected to the cylinder, a guide rail is provided on the module base plate 5211, and a screw bracket 5212 is provided on the front and rear ends of the module base plate 5211, a synchronous screw 5213 and two screw sliders 5214 fixed on the synchronous screw 5213 are fixed through the screw bracket 5212, and the two screw sliders 5214 are used to install the wire stripping knife group 52, and a driving motor is provided on the screw bracket 5212 on one side, and the synchronous screw 5213 is driven by the driving motor to rotate, so as to drive the two screw sliders 5214 to open and close synchronously, so as to make the wire stripping knife group 52 open and close.

[0044] like Figure 5 As shown, the wire stripping knife group 52 includes a cutting knife 522, a wire stripping knife 523, and a positioning knife. The cutting knife 522, the wire stripping knife 523 and the positioning knife are arranged in sequence up and down, and are driven to open and close by the knife head driving member 521. The cutting knife 522 is used to cut the wire 31 when merging, the wire stripping knife 523 is used to strip the insulation layer outside the wire 31 when merging, and the positioning knife is used to position the wire 31 when merging.

[0045] like Figure 5 As shown, the cutting knife 522 and the wire stripping knife 523 are both fixed on two lead screw sliders 5214; in fact, a plurality of groups of opposite blades are fixed on the two lead screw sliders 5214, and the cutting function or wire stripping function is achieved by adjusting the spacing or the upper and lower position relationship of the blades when they are combined; the cutting knife 522 can be obtained by staggering the upper and lower positions of the blades, and making the end faces of one side of the two blades touch each other when the blades are combined, or by making the two blades leave a gap for accommodating the wire core when the blades are combined, so as to obtain the wire stripping knife 523. The positioning knife is located below the cutting knife 522 and the wire stripping knife 523. The positioning knife is not a blade fixed on the lead screw slider 5214, but two opposite material receiving plates 524, which are positioned by clamping the guide when they are combined to facilitate better wire stripping. During operation, the blade drive 521 drives the wire stripping knife group 52 to clamp on the end of the wire 31, and trims the end of the wire 31 through the cutting knife 522, so that each wire 31 passing through the wire stripping device 5 is trimmed to the same length for easy twisting; the wire stripping knife 523 cuts off the insulation layer outside the wire 31 when closed, and drives the wire stripping knife group 52 to move upward through the wire stripping drive assembly 53 to achieve wire stripping.

[0046] Furthermore, a plurality of notches 5241 are formed on the opposite ends of the receiving plate 524. When the two receiving plates 524 are combined, the two receiving plates 524 are combined to form a receiving groove 525. The two notches 5241 are combined to form a positioning hole located in the receiving groove 525. The positioning hole is used to accommodate the wire 31. Figure 5 As shown, the positioning plate is in an "L" shape, and the two positioning plates are combined to form a "U"-shaped receiving groove 525; the stripped insulation layer will fall on the receiving groove 525. If the receiving groove 525 is not provided, the insulation layer will be scattered on the tooling 3, and the fine insulation layer may be stuck in the equipment, thereby affecting the normal operation of the equipment.

[0047] In this embodiment, a waste box is provided on one side of the receiving slot 525. By providing a blowing assembly 54 facing the receiving slot 525 on the wire stripping frame 51, air is blown toward an opening on one side of the receiving slot 525 to blow the stripped insulation layer into the waste box for collection, thereby preventing the stripped insulation layer from scattering outward. Figure 4 As shown, a slide 56 is provided between the waste box and the receiving trough 525 , and the blown-off insulation layer will fall into the waste box along the slide 56 .

[0048] In summary, this patent realizes guided automatic stripping and trimming through the wire stripping knife group 52, and increases the stability of wire stripping by setting a positioning knife; at the same time, the material receiving groove 525 structure in the positioning knife is used to effectively collect the stripped insulation layer to prevent the insulation layer from scattering and affecting the normal operation of the equipment.

[0049] Furthermore, it also includes a wire stripping positioning assembly 55, which is fixed on the wire stripping frame 51, including two opposing wire stripping positioning plates 551, and the wire stripping positioning plates 551 are connected to a linear driving member that drives them to slide, so that the two wire stripping positioning plates 551 are closed or opened; a wire stripping positioning clamping strip 552 is fixed on the wire stripping positioning plate 551, and the two opposing wire stripping positioning clamping strips 552 are staggered, so that when the two wire stripping positioning plates 551 are closed, a wire stripping positioning gap for accommodating the wire 31 is formed between the two wire stripping positioning clamping strips 552.

[0050] The wire stripping positioning assembly 55 includes a wire stripping positioning frame arranged below the wire stripping driving assembly 53. Two wire stripping positioning frames are provided, which are respectively arranged front and back between the two support arms and located in front and back of the tooling 3. The linear driving member used to drive the wire stripping positioning plate 551 to slide is fixed on the wire stripping positioning frame, which is specifically a cylinder. The wire stripping positioning clip 552 is fixed to the wire stripping positioning plate 551 by fasteners.

[0051] like Figure 1 , 3As shown, the two stripping positioning plates 551 are located on the front and rear sides of the wire 31. When the linear motion part is working, the two stripping positioning plates 551 are closed to limit the exposed wire 31 front and back. At the same time, the two staggered stripping positioning clips 552 are limited on both sides of the wire 31 to the left and right, so that the wire 31 is confined in the stripping positioning gap to achieve positioning.

[0052] Furthermore, one end of the two positioning strips is provided with a wire stripping guide slope 553 facing between the two wire stripping positioning strips 552. The wire 31 may be offset to the left and right sides thereof during installation, and the wire stripping guide slope 553 is used to first contact with the offset wire stripping guide slope 553 when the wire stripping positioning plate 551 is closed, and guide the offset wire 31 to move toward the wire stripping positioning gap between the two wire stripping and wiring clips 552 during the gradual closing of the wire stripping positioning plate 551, thereby achieving the straightening of the wire 31.

[0053] 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.
