DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Figure 1This is a schematic diagram of the wiring harness structure with exposed battery cells at both ends produced by this stripping device.

[0033] like Figure 2 As shown, the present invention provides a technical solution: a wire stripping device, comprising a chassis 1, a panel 3, a touch operation screen 2, a cutout piece 4, a traction piece 5, a transition piece 6 and a clamp 7, wherein the touch operation screen 2 is mounted on the chassis 1 for numerically controlling the device, the panel 3 is mounted on one side of the chassis 1 through a connecting bolt 301, the cutout piece 4, the traction piece 5 and the transition piece 6 are all mounted on one side of the panel 3, and a control mechanism for driving the traction piece 5 is arranged inside the chassis 1 and is mounted on the other side of the panel 3, wherein the clamp 7 is mounted on one end of the chassis 1, and the clamp 7 is the feed end of the peeling device, and the end of the chassis 1 away from the clamp 7 is the unloading end of the peeling device. The wire harness enters the chassis 1 after passing through the limit of the clamp 7. There are at least four traction members 5, and every two traction members 5 are set as a group and are symmetrically arranged up and down. A gap is set between the upper and lower traction members 5 for the wire harness to pass through. One group is set near the feed end of the chassis 1, and the other group is set near the unloading end of the chassis 1. The cutout member 4 is installed between the two groups of traction members 5, and the transition member 6 is set on one side of the cutout member 4 and installed on the panel 3.

[0034] The wire harness enters the chassis 1 after being limited by the clamp 7. The wire harness is limited at the chassis 1 between the upper and lower traction members 5. The traction members 5 limit and pull the wire harness. The stripping device is used to produce wires with exposed ends. After being pulled by a group of traction members 5 near the feed end, one end of the wire harness is cut with a cutting member 4. After the cutting is completed, the epidermis at the cut is removed. During this process, a transition member 6 is installed on one side of the cutting member 4 to provide certain support to the wire harness in the middle. Then the wire harness continues to be guided to the unloading end under the traction of the traction member 5, and the wire harness is cut off through the cutting member 4 after reaching the required length. After the cutting is completed, the cut wire harness is retracted a section through the traction member 5 and cut again through the cutting member 4. After the cutting is completed, the wire harness continues to be transported to the unloading end and the epidermis at the tail end of the wire harness is peeled off.

[0035] The details are as follows: Figure 2 and Figure 3 As shown, the clamp 7 includes a cross bar 1 701 fixed at the feed end of the chassis 1, and a cross bar 2 702 is arranged above the cross bar 1 701. The cross bar 1 701 is connected to one side of the cross bar 2 702 through a CNC cylinder 703, and the spacing between the cross bar 1 701 and the cross bar 2 702 is adjusted by the CNC cylinder 703. A plurality of limiting wheels 704 are rotatably installed on the other sides of the cross bar 1 701 and the cross bar 2 702. The wire harness enters the chassis 1 from the clamp 7 for epidermal peeling. The spacing between the cross bar 1 701 and the cross bar 2 702 can be adjusted to accommodate wire harnesses of various diameters, and the wire harness can be clamped so that the wire harness cannot be pulled forward any further.

[0036] like Figure 4 and Figure 5 As shown, each traction member 5 includes a driving wheel 501 rotatably mounted on one side of the panel 3, the axes of the two driving wheels 501 are horizontally arranged and located at the same height, the driving wheels 501 are connected by a traction belt 502, and the wire harness is pulled by the friction between the upper and lower traction belts 502. In order to increase the friction between the wire harness and improve the traction stability, the middle part of each driving wheel 501 is concave, and two shaft hoops 503 are rotatably mounted in the concave part, and the surfaces of the two shaft hoops 503 are fixed with support rods 504, and the ends of the support rods 504 are rotatably mounted There is a pressure wheel 506, and an angle is formed between the two support rods 504. The pressure wheels 506 at the ends of the two support rods 504 roll on the inner side of the bottom of the traction belt 502 and the inner side of the top of the traction belt 502 respectively. An elastic sheet 505 is arranged between the two support rods 504. The elastic sheet 505 always keeps the two support rods 504 in a separated state and allows the bottom pressure wheel 506 to press on the traction belt 502, which can make the traction belt 502 produce a certain deformation and thus produce a clamping force on the wire harness, thereby increasing the clamping force of the traction belt 502 on the wire harness and improving the traction stability.

[0037] like Figure 6 and Figure 7 As shown, the cutting member 4 includes two carrier blocks 401, which move relative to each other and move vertically on the panel 3. A cutter 402 is installed on each of the carrier blocks 401, and the cutter 402 performs cutting and cutting on the wire harness. Two vertical slots 19 are provided on the panel 3, and the carrier blocks 401 slide in the vertical slots 19. A connecting block 18 fixed to the carrier blocks 401 is provided on the other side of the panel 3. A telescopic member 17 installed on the panel 3 is provided between the two connecting blocks 18. The telescopic member 17 is a driving device such as a bidirectional screw telescopic arm or a bidirectional cylinder that can realize synchronous telescopic movement of both ends. The two cutters 402 are in an arc shape and are as compatible as possible with the curvature of the wiring harness surface. The two cutters 402 are attached to each other on one side. When the wiring harness is cut, the two cutters 402 are staggered to increase the incision depth until the wiring harness is cut. However, when the incision is performed, in order to reduce the risk of the cutter 402 damaging the internal wire core, the incision depth is limited. After cutting, there may still be adhesion at the incision. The skin at the incision is peeled off from the wiring harness body through the friction of the traction member 5.

[0038] like Figure 7 and Figure 8As shown, the transition piece 6 includes a turntable 602 rotatably mounted on one side of the panel 3, a conduit 601 is fixed on one side of the turntable 602, the wire harness passes through the conduit 601, and provides certain support for the wire harness, and a driving source 16 for driving the turntable 602 is installed on the other side of the panel 3. The turntable 602 is driven to rotate by the driving source 16 so that the angle of the conduit 601 changes. After the wire harness is cut off, it needs to be retracted a section. In order to play a good guiding role, the inner wall diameter of the conduit 601 is slightly larger than the diameter of the wire harness. In order to avoid the cut wire harness being difficult to be inserted back into the conduit 601 in a deformed state due to the soft nature of the wire harness during the retraction process, the turntable 602 is driven to rotate by the driving source 16 to rotate the conduit 601, so that the conduit 601 makes way for the retraction path of the wire harness to avoid obstruction of the retracted wire harness.

[0039] To achieve the above steps and control the traction member 5, Figure 7 and Figure 8 The control mechanism includes gear 1 8, gear 2 9, gear 3 10 and two gear 4s 14, which are all installed on the side of the panel 3 away from the traction member 5. Gear 1 8 is coaxially connected to the driving wheel 501 located above the cutter 402 and close to the discharge end. Gear 2 9 and gear 3 10 are coaxially connected to the driving wheels 501 located on both sides of the cutter 402 and below. The two gear 4s 14 are coaxially connected to the upper and lower driving wheels 501 closer to the feed end. The two gear 4s 14 are meshed and connected. Gear 1 8 is meshed and connected with gear 2 9. A coaxially arranged belt shaft 2 13 is installed on one side of the gear 2 9, and a coaxially arranged belt shaft 1 11 is installed on one side of the gear 3 10. The belt shaft 11 and the belt shaft 2 13 are connected by a transmission belt 12. Through the above-mentioned structural arrangement, the driving wheels 501 in the upper and lower groups of traction members 5 near the discharge end rotate in opposite directions, and the wire harness is pulled by the friction between the two traction belts 502. The adjacent sides of the two groups of traction belts 502 have the same movement direction. For example, when the driving wheel 501 located near the feed end and located above rotates counterclockwise (with a rotation direction of 1 / 200 mm / s), the gear 3 10 rotates counterclockwise (with a rotation direction of 1 / 200 mm / s). Figure 8 As shown in the figure, the bottom of the traction belt 502 located above moves toward the feeding end, and the driving wheel 501 located below will rotate clockwise under the meshing effect, and the top side of the traction belt 502 below moves toward the feeding end, thereby achieving the purpose of entraining the wire harness for traction. Under this effect, gear three 10 and gear two 9 rotate in the same direction, and gear two 9 and gear one 8 move in opposite directions under the meshing effect, so that the two traction members 5 near the discharge end can be moved toward the discharge end with the entrained wire harness. A driving source one 15 is installed on the side of the panel 3 away from the traction member 5. The driving source one 15 is connected to a driving wheel 501 near the discharge end, and is driven by the driving source one 15 to control the movement of the four traction members 5.

[0040] In summary, if Figure 8As shown, the working steps of the device are briefly described as follows:

[0041] The wire harness is loaded from the clamp 7, and the loading is done manually. The wire harness is passed from the clamp 7 to the chassis 1, and then inserted into the guide tube 601 of the transition piece 6 after passing through a set of traction pieces 5. Then, the four traction pieces 5 rotate synchronously to pull the wire harness to the discharge end. After reaching the required position, it is cut by the cutter 402, and the cutter 402 is maintained at the cutting position. At this time, the clamp 7 clamps the wire harness, and then the traction piece 5 continues to guide the wire harness to the discharge end. Since the clamp 7 clamps the wire harness, the wire harness can no longer be pulled to the discharge end by the traction piece 5. The skin at the incision is about to be separated from the main body of the wire harness due to being cut by the cutter 402. When the traction member 5 continues to pull the wire harness toward the discharge end, the wire harness cannot move. The skin at the incision is in frictional contact with the traction belt 502 of the traction member 5, so that the skin that is about to be separated from the wire harness is separated from the main body of the wire harness under the action of friction, completing the skin peeling at one end of the wire harness. Then the clamp 7 is opened, and the wire harness is continued to be transported to the discharge end through the traction member 5. After reaching the required length of the wire harness, the wire harness is cut off. After cutting, the wire harness is retreated a section under the control of the traction member 5 and is pulled forward again. The transition piece 6 is located on the retreat path of the cut wire harness. To prevent the transition piece 6 from blocking the retreat wire harness, the transition piece 6 rotates so that the conduit 601 is no longer horizontal, leaving a distance behind the cutter 402, so that the wire harness is retreated a section under the action of the traction piece 5 and cut by the cutter 402. Although the main body of the wire harness is also forced to retreat a distance, due to its soft nature, the wire harness will not deviate from the traction path and will not affect the traction of the subsequent wire harness. At the same time, the retreat distance of the wire harness does not exceed the length of the conduit 601, so as to prevent the wire harness from being separated Conduit 601, at this time, the cutter 402 stays at the incision, and the traction member 5 continues to transport the cut wire harness to the unloading end, and the skin at the end of the cut wire harness is stuck by the cutter 402 and will be peeled off the wire harness, completing the peeling of the skin at both ends of the wire harness. At this time, the clamp 7 is in a clamping state again, allowing the wire harness body to stay in the current position to prevent the wire harness from contacting the detached wire harness skin during the forward movement. Through the above process, the production of a section of wire harness with exposed skin at both ends is completed, and the above process can be repeated to achieve continuous peeling of the wire harness skin and realize automated production.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
