Description

Technical Field

[0001] This utility model belongs to the field of cable lamp processing technology, specifically relating to a cable stripping device for cable lamp processing. Background Technology

[0002] Cord lamps are a common type of decorative lighting fixture. For example, as shown in CN202223470421.X, a cord lamp typically uses a three-wire cable arranged in parallel. The cable is stripped at equal intervals, and then LED beads are installed at the stripped locations. The LED beads are then connected to the conductive wires within the cable to achieve conductivity. This requires stripping the wire using a wire stripper or laser stripping before soldering the LED beads. While this method satisfies the need for wire stripping, laser stripping is expensive, and the melted insulation can easily adhere to the conductive wires, increasing the failure rate of subsequent LED bead soldering. This results in material waste, reduced processing efficiency, and higher maintenance costs, thus limiting its applicability. Summary of the Invention

[0003] The purpose of this invention is to provide a cable stripping device for processing fiber lamps with a reasonable structural design that helps reduce costs.

[0004] The technical solution to achieve the purpose of this utility model is a cable stripping device for processing a wire lamp, including a guide rail fixed on a processing table.

The lower part of the mounting block is mounted on the guide rail, and the support frame is fixed on the mounting block; The conductor seat is fixed on the support frame, and the top surface of the conductor seat is provided with a conductor groove. The depth of the conductor groove is less than the thickness of the cable, and when the cable is in the conductor groove, the upper surface of the cable protrudes from the top surface of the conductor seat. The first wire clamping structure is fixed at the inlet end of the conductor seat and is used to clamp and limit the cable. The second wire clamping structure is fixed on the support frame and located at the outlet end of the conductor seat, used to clamp and limit the cable. The wire upper sheath stripping structure is installed on the wire seat and is used to strip the upper sheath of the cable that needs to be cut out in the wire groove. The lower sheath removal structure is fixed on the support frame and is located between the upper sheath cutting structure and the second pressing structure. It is used to press down on the cable with the upper sheath cut off to remove the corresponding lower sheath. The translation adjustment structure is fixed at one end of the bottom of the conductor seat and connected to the upper sheath cutting structure of the wire, and is used for reciprocating translation control of the upper sheath cutting structure of the wire.

[0006] A further preferred embodiment is that the upper sheath cutting structure of the wire includes a support frame, a lifting control cylinder, a tool holder, and an inclined tool; The wire seat has a translation guide groove on its symmetrical side, and a translation guide slider is provided on the symmetrical inner wall of the support frame.

[0007] A further preferred embodiment is that the translation adjustment structure is a translation adjustment cylinder.

[0008] A further preferred embodiment is that the wire lower sheath removal structure includes a lifting cylinder, a removal blade holder, and an n-shaped blade. The lifting cylinder body is vertically fixed on the support frame, the top removal tool holder is fixed on the piston shaft of the lifting cylinder body, and the n-shaped tool body is fixed on the bottom surface of the top removal tool holder; A hollow chip removal channel is provided on the bottom wall of the wire groove, and the chip removal channel is located directly below the n-shaped cutter body; The width of the recessed area of ​​the n-shaped blade is the same as the diameter of the conductive part in the middle of the cable; The n-shaped blade moves downward, and the two vertical rods move downward from the adjacent conductive part of the cable and remove the corresponding lower skin that has been stripped of the upper skin.

[0009] A further preferred embodiment is that the first wire pressing structure includes a wire pressing support, a lifting and adjusting cylinder, a wire pressing block, and a wire pressing head; The bottom of the wire pressing support is fixed to the side of the wire inlet end of the wire seat, the lifting and adjusting cylinder is fixed on the wire pressing support, the wire pressing block is fixed on the piston shaft of the lifting and adjusting cylinder, and the wire pressing head is located on the wire pressing block.

[0010] A further preferred embodiment is that the second wire pressing structure includes a wire pressing finger cylinder and two wire pressing components; The extension and retraction of the pressing finger cylinder causes the two pressing parts to clamp or loosen.

[0011] A further preferred embodiment includes a PLC controller that connects to and drives the wire stripping and insulation removal structures. The PLC controller is a conventional structure found in existing technology, simply applied to achieve evenly spaced insulation removal on the cable.

[0012] Its working principle is briefly described as follows: the cable moves horizontally in the conductor groove under the traction of the external traction structure. When it passes the stripping cutting structure, the first finger cylinder is activated and clamps and positions the cable. At this time, the second finger cylinder is activated, causing the upper and lower cutting blades to move and cut the top and bottom surfaces of the cable. The first and second finger cylinders are then reset. When the cable is moved into the stripping and sheathing structure, the first clamping structure is activated to clamp and position the cable. At this time, the cable is in the conductor groove and the upper sheath of the cable protrudes from the top surface of the conductor groove. The translation adjustment structure drives the upper sheath stripping structure to move and removes the protruding upper surface of the cable through the inclined cutter. After the removal, the first clamping structure loosens, and the cable moves to the lower sheath removal structure under the action of the traction structure. At this time, the second clamping structure is activated to clamp and limit the cable. The lower sheath of the cable is removed by moving the structure downwards and passing through the cable between adjacent conductive cores via an n-shaped blade. Since the upper sheath of the cable has already been removed and there are cuts at both ends, the remaining lower sheath will be pushed away from the conductive cores of the cable as the n-shaped blade descends and discharged from the chip removal channel, thus completing the equal-spaced removal of the cable's outer sheath.

[0013] This invention has several advantages: its structure is rationally designed, enabling efficient and rapid sequential cutting, removal of the upper and lower sheaths of the cable, thus improving processing effectiveness and stability. Furthermore, the overall structure eliminates the need for laser components, reducing overall cost. It also avoids damage to the cable, enhancing the sheathing effect and efficiency, facilitating subsequent LED welding, increasing yield, reducing processing costs, and demonstrating strong applicability.
