Description

Technical Field

[0001] The present invention relates to the technical field of wire harness manufacturing, and in particular to a wire harness tape winding device. Background Art

[0002] The wires on the wiring harness of electric drive vehicles are generally made of multi-strand copper wires, with PVC attached to the outer surface as an insulation layer. Such automotive wiring harnesses need to have good physical properties such as high temperature resistance, oil resistance, waterproofness and flame retardancy. However, under external shear conditions, the peak load of the electric drive automotive wiring harness is still significantly higher than the failure load. Therefore, the winding tape on the surface of the high-voltage wiring harness is still an essential key process in the automotive wiring harness processing. However, when using tape to wind the automotive wiring harness, the following problems exist:

[0003] (1) When the adhesive tape itself has a large adhesion force, such as cloth-based tape, in the initial stage of the adhesion and winding of the cloth-based tape and the automotive wiring harness, since the cloth-based tape requires a large unwinding force, the unwinding force acting on the cloth-based tape will react on the automotive wiring harness, and the automotive wiring harness will produce a large torsion. However, the torsion angle of the automotive wiring harness is generally required to be less than 180°, so it does not meet production needs.

[0004] (2) During the winding process of the tape and the automotive wiring harness, since the automotive wiring harness is a flexible material, when the rotating winding mechanism acts on the surface of the automotive wiring harness, the automotive wiring harness will produce huge disturbances, and then the tape will be offset during the winding process with the automotive wiring harness. However, conventional rigid clamping will cause certain damage to the automotive wiring harness. Summary of the Invention

[0049] The balancing weight 312 is clamped by the finger cylinder 309 in conjunction with the clamping piece 311, and then the balancing weight 312 is detachably connected to both ends of the rotating bar 208, so that the balancing weight 312 and the rotating bar 208 are combined into a circular ring structure with uniform mass distribution;

[0052] In this embodiment, the balancing mechanism 30 also includes a rodless cylinder 301 and a guide bar 306. The rodless cylinder 301 is mounted on the front half of the slide 1 202 in a front-to-back direction, and is horizontally connected to the slide 302 on its pneumatic component. The top of the slide 302 is horizontally connected to a hinge plate 303, and a hinge frame 305 is parallelly hinged above the hinge plate 303 through two pairs of hinge bars 304. The guide bar 306 is an inverted L-shaped structure and is vertically mounted on the slide 1 202. In the front half of the hinge 305, the guide bar 306 is provided with an inverted L-shaped guide groove 306a. The hinge frame 305 is a T-shaped structure with a guide post 307 vertically connected to its lower end. The guide post 307 slides into the guide groove 306a. The finger cylinder 1 309 is mounted horizontally and rearwardly on the hinge frame 305 via a fixing plate 1 308. The pneumatic fingers of the clamping arm 1 310 are connected to the clamping arm 1 310, and the clamping piece 1 311 is fixed to the overhanging end of the clamping arm 1 310. The clamped balance weight 312 is driven by the rodless cylinder 3 301 to first rise and then move backward until the balance weight 312 is inserted into both ends of the rotating bar 208. The finger cylinder 1 309 then deploys its pneumatic fingers and releases the balance weight 312.

[0053] In this embodiment, T-shaped insertion slots 208a are provided at both ends of the rotating bar 208, and an insertion hole 208b is provided in the center of the bottom of the insertion slot 208a. The balance weight 312 includes an installation frame 3121. T-shaped insertion strips 3122 are symmetrically provided on the upper and lower sides of the installation frame 3121. The insertion strips 3122 are in sliding fit with the insertion slots 208a. A pair of installation strips 3123 are symmetrically and slidably connected in the installation frame 3121. Two sets of upper and lower hinge pieces 3124 are hinged between the pair of installation strips 3123. Each set of hinge pieces 3124 is vertically hinged with an insertion column 3125. The insertion column 3125 is slidably connected with the installation frame 3121, and the insertion column 3125 is slidably connected with the insertion hole 208b. Two pairs of compression springs 3126 are centrally connected between the pair of installation strips 3123. The balance weight 312 is inserted into both ends of the rotating bar 208 under the action of the rodless cylinder three 301, and the insertion strips 3122 are inserted into the insertion slots 208a. After the finger cylinder one 309 releases the balance weight 312, the distance between the left and right installation strips 3123 will expand under the action of the compression springs 3126, and the upper and lower insertion columns 3125 will be pushed to extend out of the installation frame 3121 under the transmission of the two sets of hinge pieces 3124 until the upper and lower insertion columns 3125 are correspondingly inserted into the insertion holes 208b at both ends of the rotating bar 208, thereby quickly and reliably installing the balance weight 312 on the rotating bar 208.

[0054] In this embodiment, the finger cylinder two 402 is horizontally and inwardly installed on the workbench 10 through a C-shaped fixing plate two 401. A clamping arm two 403 is connected to the pneumatic finger of the finger cylinder two 402, and a clamping piece two 404 is fixed to the overhanging end of the clamping arm two 403. By closing the fingers of the finger cylinder two 402 and clamping the end of the wire harness 70, it is avoided that manual workers hold both ends of the wire harness 70.

[0055] In this embodiment, L-shaped extension strips 605 are connected to the sides of the pair of clamping arms three 403, and a glue-breaking scissors 606 is hinged between the pair of extension strips 605. By expanding the fingers of the finger cylinder two 402 and closing the glue-breaking scissors 606, it is avoided that manual workers cut the tape short.

[0056] In this embodiment, a "U"-shaped positioning plate 405 is connected to the upper side of the fixing plate one 401. The opening size of the positioning plate 405 is smaller than the cross-sectional size of the wire harness terminal 80. By clamping the wire harness terminal at the end of the wire harness through the positioning plate 405, it is avoided that manual workers straighten the wire harness 70.

[0057] This embodiment also includes a limiting mechanism 50, comprising a finger cylinder 3 502 and a limiting wheel 504. The finger cylinder 3 502 is mounted on the slide 1 202 via a T-shaped fixing plate 3 501. The pneumatic fingers of the finger cylinder 3 502 are connected to a clamping arm 3 503, and the limiting wheel 504 is rotatably connected to the overhanging end of the clamping arm 3 503. The finger cylinder 3 502 closes its fingers and drives the upper and lower limiting wheels 504 to surround the wire harness 70, thereby limiting the range of movement of the wire harness 70 during tape winding.

[0058] This embodiment also includes a gluing mechanism 60, which includes a dual-axis cylinder 602 and a gluing block 603. The dual-axis cylinder 602 is mounted to the mounting plate 207 via an L-shaped side mounting plate 601. The dual-axis cylinder 602 is horizontally positioned forward, with the gluing block 603 mounted on the end of its piston rod. The front side of the gluing block 603 is provided with a semi-cylindrical gluing port 603a, and suction ports 603b are evenly distributed on the wall surface of the gluing port 603a. The gluing block 603 is hollow internally and connected to a suction pipe 604 at its top. The extension of the piston rod of the dual-axis cylinder 602 drives the gluing block 603 forward. When the suction ports 603b on the gluing block 603 attract the released tape, the gluing block 603 moves forward synchronously with the tape. When the tape contacts the stretched wire harness, the free end of the tape is firmly adhered to the surface of the wire harness 70, eliminating the need for manual tape application.

[0059] The working principle of this wire harness tape winding equipment:

[0060] S1: Manually straighten the wire harness 70 with wire harness terminals 80 crimped at both ends, and place the left and right terminals 80 correspondingly on the outside of the positioning plates 405 on both sides, and then close the fingers of the finger cylinders 402 on both sides to clamp the two ends of the wire harness 70;

[0061] S2: The rodless cylinder 1 201 and the rodless cylinder 2 203 jointly drive the rotating bar 208 to move in the plane and approach the left end of the wiring harness 70. At this time, the rotating bar 208 and the wiring harness 70 are coaxially distributed. Then, the rotating cylinder 205 drives the rotating bar 208 to deflect counterclockwise by a certain angle.

[0062] S3: The clamped balance block 312 is driven by the rodless cylinder 301 to first rise and then move backward until the balance block 312 is inserted into both ends of the rotating bar 208, and then the finger cylinder 1 309 expands its pneumatic fingers and releases the balance block 312;

[0063] S4: The piston rod of the dual-axis cylinder 602 extends, driving the adhesive block 603 to move forward. When the suction port 603b on the adhesive block 603 absorbs the released adhesive tape, it moves forward synchronously with the adhesive tape until the free end of the adhesive tape is firmly attached to the surface of the wiring harness 70.

[0064] S5: The motor 211 drives the rotating bar 208 to rotate and wind the tape on the tape roll 214 onto the wiring harness 70. At the same time, the rodless cylinder 201 moves the rotating bar 208 to the right, thereby spirally wrapping a layer of tape around the entire surface of the wiring harness 70. During the wrapping process, the finger cylinder 502 closes its fingers and drives the upper and lower limiting wheels 504 to surround the wiring harness 70, thereby limiting the movement range of the wiring harness 70 when winding the tape.

[0065] S6: The pneumatic fingers of the finger cylinder 1 309 are closed to clamp the balance weight 312, and the clamped balance weight 312 is driven forward and downward by the rodless cylinder 3 301;

[0066] S7: The finger cylinder 2 402 is used to unfold its fingers and close the glue-cutting shears 606, and finally the glue-wrapped wire harness 70 is taken away.

[0067] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
