Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire stripping device technology, specifically a mechanism for stripping the insulation from the same side of a U-shaped conductor. Background Technology
[0002] As an important component of automobiles, brake sensors contain wires as raw materials. The wires need to be cut at a certain distance, stripped of insulation at the ends, and riveted with terminals before they can proceed to the next processing step. The conventional processing method is to strip the insulation of one end of the wire, rivet the terminal, cut off the other end, and then repeat the above stripping and riveting steps. Although this process does not take long, it will consume a lot of time when there are too many products to process, thus affecting the overall production efficiency.
[0003] Therefore, designing a device that can simultaneously peel off the insulation from both ends to improve processing efficiency is the problem that the inventors wanted to solve. Utility Model Content

Detailed Implementation
[0020] The present invention will be further described below with reference to specific embodiments. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0021] See Figures 1 to 3 This utility model provides schematic diagrams of the conductor gripping station 3, the wire stripping station, and the wire stripping cutter. It describes a U-shaped conductor 3 side-mounted wire stripping mechanism, comprising a main frame 1, a wire feeding device 2 mounted on the main frame 1, which can precisely feed the conductor 3 as needed, a first mounting bracket 4 connected to the end face of the main frame 1, a guide tube 5 mounted on the side wall of the main frame 1 and at the output end of the wire feeding device 2, and a support frame 10 mounted at the end of the guide tube 5. The conductor 3 passes through the guide tube 5, and a through hole is opened on the end face of the support frame 10. The conductor 3 passes sequentially through the guide tube 5 and the through hole.
[0022] The first mounting bracket 4 is equipped with a transmission structure 7, which includes a housing. Inside the housing, there are two meshing drive gears and driven gears. The output end of the transmission structure 7 is fixedly connected to a blade 9 via a fly knife shaft 8. The input end of the transmission structure 7 is connected to a fly knife motor 6. The drive gear is fixedly connected to the output end of the fly knife motor 6, and the driven gear is fixedly connected to the fly knife shaft 8. The movement trajectory of the blade 9 passes through the inside of the support frame 10 and does not contact the support frame 10. When the fly knife motor 6 drives the blade 9 to rotate, it can easily cut the wire 3.
[0023] A second mounting bracket 11 is mounted on the first mounting bracket 4. A torque motor 12 is mounted on the upper end of the second mounting bracket 11. The output end of the torque motor 12 passes through the second mounting bracket 11 and is connected to a rotating plate 14. A pneumatic two-finger gripper 13 is connected to the lower end face of the rotating plate 14. The starting position of the rotating plate 14 is parallel to the vertical direction and located on the side of the torque motor 12 away from the fly knife motor 6. The rotation angle of the rotating plate 14 is 180° and the rotation range is within a 180° clockwise rotation from the starting position. When rotated 180°, the two grippers of the pneumatic two-finger gripper 13 are respectively set on both sides of the circular hole opened on the support frame 10 and do not contact the support frame 10. After the blade 9 cuts the wire 3, the torque motor 12 drives the rotating plate 14 to rotate, thereby driving the pneumatic two-finger gripper 13 to reach the side of the support frame 10 to start and clamp the end of the wire 3. After clamping the end of the wire 3, the torque motor 12 rotates in the opposite direction, carrying the end of the wire 3 to draw an arc trajectory to reach below the starting position of the rotating plate 14, so that the wire 3 bends into a U shape.
[0024] A fourth mounting bracket 27 is connected to the end face of the main frame 1. A fifth mounting bracket 32 is mounted on the fourth mounting bracket 27. A lower blade holder 31 is located at the edge of the fourth mounting bracket 27, and a lower cutter 34 is mounted on the lower blade holder 31. A second cylinder 28 is located on the upper end face of the fifth mounting bracket 32. The output end of the second cylinder 28 passes through the fifth mounting bracket 32 and is connected to a connecting plate 29. An upper blade holder 30 is located at the lower end of the connecting plate 29. An upper cutter 33 is mounted on the upper blade holder 30. Two symmetrically distributed upper cutters 33 are mounted on the upper blade holder 30 by bolts. The upper cutters 33 have right-angle cutting edges. Opposite to the lower cutter holder 31, two symmetrically distributed lower cutters 34 are bolted onto the lower cutter holder 31. The lower cutters 34 and the upper cutter 33 have the same structure and are positioned opposite each other. The lower cutters 34 and the upper cutter 33 are positioned opposite each other and are staggered in the vertical direction. When the upper cutter holder 30 is pressed down, the blades on the aligned upper cutter 33 and the lower cutter 34 approach each other and close to cut the wire sheath of the wire 3 inside. When the second cylinder 28 reaches its maximum extension distance, the blade of the upper cutter 33 does not contact the wire core of the wire 3. The upper cutter 33 and the lower cutter 34 just cut into the inside of the wire sheath without damaging the wire core.
[0025] A sliding frame 23 is provided on the side of the main frame 1. A pair of symmetrically distributed guide rods 21 are fixed to the inner side of the sliding frame 23 by nuts. A lead screw 24 is provided between the two guide rods 21. The end of the lead screw 24 passes through the side wall of the sliding frame 23 and is connected to a translation motor 22. A slide groove is provided on the left side wall of the sliding frame 23. A third mounting plate 17 is provided inside the slide groove. Two symmetrically distributed slide rails 18 are provided on the third mounting plate 17. A slider 16 is slidably provided on the outer side of the slide rails 18. The upper ends of the two sliders 16 are connected by a base plate. Two symmetrically distributed pneumatic cable clamps 15 are provided at both ends of the upper surface of the base plate. A first cylinder 20 is connected to the lower edge of the base plate by a connector 19. The first cylinder 20 is fixed to the third mounting frame by a fixing member. The right end of the third mounting plate 17 is provided with Located below the slide rod, the third mounting plate 17 is provided with four symmetrically distributed sliding sleeves 25. A threaded sleeve 26 is provided between the four sliding sleeves 25. The four sliding sleeves 25 are slidably connected to the two slide rods respectively. The threaded sleeve 26 is threadedly connected to the lead screw 24. The pneumatic cable clamp 15 includes two flip-up clamping blocks. The clamping blocks are connected to the base through a pin. The end of the base is hinged to a reversing cylinder through a pin. The reversing cylinder is hinged to the base through a pin. The action of the translation motor 22 can drive the third mounting plate 17 to slide along the axial direction of the lead screw 24. The action of the first cylinder 20 can drive the base plate to slide along the slide rail 18, thereby driving the pneumatic cable clamp 15 to slide along the axis of the first cylinder 20. The height of the slider 16 is relatively high, supporting the base plate so that the wire 3 will not be hooked to the first cylinder 20.
[0026] When the pneumatic cable clamp 15 moves along the axis of the lead screw 24, the first cylinder 20 is in a retracted state and at its minimum stroke. When the pneumatic cable clamp 15 is about to clamp the wire 3, the axes of the two pneumatic cable clamps 15 are aligned with the center lines of the guide tube 5 and the pneumatic two-finger gripper 13, respectively, and the first cylinder 20 is in an extended state and at its maximum stroke. When the pneumatic cable clamp 15 sends the wire 3 into the stripping station, the first cylinder 20 is in an extended state and at its maximum stroke. The center distance between the two upper cutters 33 is the same as the center distance between the two pneumatic cable clamps 15. When the upper cutter 33 and the lower cutter 34 close alternately, the first cylinder 20 retracts, causing the wire 3 to leave the range of the cutter and stripping the insulation from both ends at once.
[0027] This utility model uses a torque motor 12 to drive a pneumatic two-finger gripper 13 to flip the wire end of the wire 3 and bend the wire 3 into a U-shape. The bent wire 3 is then displaced by a movable and adjustable pneumatic cable clamp 15, and both ends of the wire 3 are simultaneously fed into the cutting blade for stripping. This achieves the function of stripping the wire insulation from both ends at the same time, thus improving processing efficiency.
