Description

Technical Field

[0001] This utility model relates to the field of high-precision cable processing, specifically to a high-precision double-head ultraviolet wire stripping machine with adjustable vertical position, which is particularly suitable for ultra-fine wire diameter, high-precision insulation layer stripping and sensitive material processing (such as fluoropolymers, polyimide, etc.). Background Technology

[0002] Laser cutting uses an invisible laser beam instead of a traditional mechanical blade, offering advantages such as high precision, fast cutting speed, no limitation on cutting patterns, automatic layout for material savings, smooth cuts, and low processing costs. It is gradually improving upon or replacing traditional metal cutting equipment. However, current laser wire stripping machines are generally single-head machines, using only one laser head for wire stripping, resulting in very low efficiency. Furthermore, when using a blade to strip the aluminum foil, residual aluminum foil in the width direction of the wire is not completely removed, ultimately affecting the product transmission rate.

[0003] Therefore, it is necessary to develop a dual-head laser wire stripping machine to improve work efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-precision, vertically adjustable dual-head ultraviolet wire stripper. Based on the traditional laser wire stripper, it has been optimized for the characteristics of ultraviolet laser.

[0005] The purpose of this utility model is achieved through the following technical solution: This high-precision, vertically adjustable dual-head UV wire stripper includes a cabinet and a first handwheel and a second handwheel located on the top of the cabinet. Two lead screws are vertically arranged inside the cabinet. One lead screw is movably connected to an upper movable plate via a lead screw nut and is driven by the first handwheel. The other lead screw is movably connected to a lower movable plate via a lead screw nut and is driven by the second handwheel. A laser is fixed to the surface of both the upper and lower movable plates. The front of each laser extends out of the cabinet and is mounted with a galvanometer via a galvanometer connecting cylinder. Focusing lenses are arranged on opposite sides of the two galvanometers, ensuring that the centers of the two focusing lenses are collinear. Vertical adjustment is achieved by rotating the first handwheel and / or the second handwheel.

[0006] As a further technical solution, a locking block is installed on the cabinet at the position corresponding to the first and second handwheels.

[0007] As a further technical solution, the cabinet is made of aluminum alloy.

[0008] As a further technical solution, several guide rods are installed vertically inside the cabinet, with each guide rod passing through the upper and lower movable plates in sequence.

[0009] As a further technical solution, guide sleeves are installed at the corresponding positions of the upper and lower movable plates and each guide rod.

[0010] As a further technical solution, a control knob is installed on the front of the cabinet. The control knob is electrically connected to the two lasers and is used to control the two lasers to work simultaneously or one of them to work.

[0011] As a further technical solution, a dust cover is installed at the point where each laser exits the cabinet.

[0012] As a further technical solution, the focusing lens is mounted on the galvanometer via an adapter ring.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The up and down position adjustment is controlled by a lead screw, eliminating the need for an external power mechanism and saving energy;

[0015] 2. The lead screw adopts a trapezoidal lead screw, which can self-lock in the absence of power to prevent the load from slipping. At the same time, it is used with a locking block for double locking, which further improves stability and reliability.

[0016] 3. The meshing transmission clearance between the lead screw and nut is small, the lead error is controllable, and high repeatability of motion can be achieved with a low error rate;

[0017] 4. The cabinet adopts an all-aluminum alloy design, forming a Faraday cage effect through an integrated metal structure, shielding external electromagnetic interference and internal radiation leakage, and protecting sensitive equipment; moreover, it can be integrated with the equipment grounding system to eliminate the risk of static electricity accumulation, making it highly integrated and lightweight.

[0018] 5. It adopts a double-head stripping method to process both ends of the cable at the same time, or to operate different cables independently, thereby improving efficiency. The power and frequency of the two heads can be adjusted independently to meet the needs of different materials or wire diameters. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings:

[0025] Example: As attached Figures 1-4 As shown, this high-precision, vertically adjustable double-head UV wire stripper includes a first handwheel 1, a second handwheel 2, a locking block 3, a cabinet 4, a guide rod 5, a lead screw 6, a lead screw nut 7, a guide sleeve 8, an upper movable plate 9, a lower movable plate 10, a laser 11, a galvanometer connecting cylinder 12, a galvanometer 13, an adapter ring 14, a focusing lens 15, a dust cover 16, and a control knob 17.

[0026] Reference Appendix Figure 1 , 3 A first handwheel 1 and a second handwheel 2 are installed at the top of the cabinet 4. Two lead screws 6 are vertically installed inside the cabinet 4. The first lead screw 6 is movably connected to the upper movable plate 9 via a lead screw nut 7 and is driven by the first handwheel 1. The second lead screw 6 is movably connected to the lower movable plate 10 via a lead screw nut 7 and is driven by the second handwheel 2. Figure 2 As shown, a laser 11 is fixed on the surface of both the upper movable plate 9 and the lower movable plate 10. The front of each laser 11 extends out of the cabinet 4 and is mounted with a galvanometer 13 via a galvanometer connecting tube 12. A focusing lens 15 is set on one side of each of the two galvanometers 13 facing each other, so that the centers of the two focusing lenses 15 are collinear. In use, the vertical position of the focusing lens 15 (laser 11) can be adjusted by rotating the first handwheel 1 and / or the second handwheel 2.

[0027] like Figure 1 , 3 As shown, a locking block 3 is installed on the cabinet 4 at the position corresponding to the first handwheel 1 and the second handwheel 2, forming a double locking with the self-locking of the trapezoidal screw, which further improves stability and reliability.

[0028] Preferably, the cabinet 4 is made of aluminum alloy material, and the integrated metal structure forms a Faraday cage effect to shield external electromagnetic interference (EMI) and internal radiation leakage, protecting sensitive equipment; moreover, it can be integrated with the equipment grounding system to eliminate the risk of static electricity accumulation.

[0029] Reference Appendix Figure 3Four guide rods 5 are vertically arranged inside the cabinet 4, and each guide rod 5 passes through the upper movable plate 9 and the lower movable plate 10 in sequence. Preferably, the four guide rods 5 are located at the four corners of the upper movable plate 9 and the lower movable plate 10, respectively. A guide sleeve 8 (flange type linear bearing) is installed at the corresponding position of each guide rod 5 on the upper movable plate 9 and the lower movable plate 10.

[0030] Furthermore, such as Figure 1 , 2 As shown, a control knob 17 is installed on the front side of the cabinet 4. The control knob 17 is electrically connected to two lasers 11 and is used to control the two lasers 11 to work simultaneously or one of them to work independently, so as to adjust the power and frequency to meet the requirements of different materials or wire diameters. A dust cover 16 is installed at the position where each laser 11 protrudes from the cabinet 4 to prevent dust from entering the cabinet 4.

[0031] like Figure 4 As shown, the focusing lens 15 is mounted on the galvanometer 13 via an adapter ring 14.

[0032] The working process of this utility model:

[0033] Before stripping the wire, first rotate the first handwheel 1 and the second handwheel 2 to adjust the relative positions of the upper and lower focusing lenses 15 (laser 11). After adjustment, double locking is achieved using the self-locking of the trapezoidal lead screw and the locking block 3. Then, control the operation of the upper and lower lasers 11 by controlling the knob 17, which can cut simultaneously or individually to ensure accuracy and consistency.

[0034] The working principle of this utility model:

[0035] I. Principle of Ultraviolet Laser Wire Stripping

[0036] 1. Characteristics of ultraviolet lasers

[0037] - Short wavelengths (e.g., 355nm): High photon energy can directly break the chemical bonds of materials ("cold processing"), rather than thermal ablation, reducing the heat-affected zone (HAZ) and avoiding damage to conductors or surrounding insulation layers.

[0038] - High-precision focusing: The shorter the wavelength, the smaller the focused spot (up to the micrometer level), which is suitable for the layer-by-layer stripping of ultra-fine cables (such as 0.02mm²) or multi-layer insulation structures.

[0039] 2. Material compatibility

[0040] - Polymer materials: such as PVC, TPU, PI (polyimide), PTFE (Teflon), etc., ultraviolet lasers decompose the materials through photochemical action, resulting in neater edges.

[0041] - Metal protection: Ultraviolet lasers have high reflectivity to conductors such as copper and aluminum, which can prevent the conductor surface from being ablated.

[0042] 3. Dual-head collaborative mode

[0043] - Parallel processing: Simultaneously process both ends of the cable, or operate different cables independently, improving efficiency.

[0044] - Differentiated parameters: The dual heads can independently adjust the power and frequency to meet the needs of different materials or wire diameters (such as stripping the insulation layer at one end of the cable and stripping the shielding layer at the other end).

[0045] II. Rack Characteristics

[0046] The cabinet adopts an all-aluminum alloy design, forming a Faraday cage effect through an integrated metal structure to shield external electromagnetic interference (EMI) and internal radiation leakage, protecting sensitive equipment; it can also be integrated with the equipment grounding system to eliminate the risk of static electricity accumulation.

[0047] III. Lifting Mechanism

[0048] 1. High-precision positioning

[0049] The lead screw and nut have a small meshing transmission clearance, controllable lead error, and can achieve highly repeatable motion with a low error rate.

[0050] 2. High load capacity

[0051] Rigid structure: The material and heat treatment process (quenching and grinding) of the lead screw give it high compressive strength, and a single lead screw can withstand a vertical load of several tons.

[0052] Uniform load distribution: The load is distributed along the axial direction of the lead screw, avoiding local stress concentration, which is suitable for equipment lifting.

[0053] 3. Self-locking function

[0054] Trapezoidal lead screw self-locking: The lead screw can self-lock in the absence of power to prevent the load from slipping.

[0055] External locking: It can be locked using a specially designed locking block.

[0056] 4. Compact structure and modular design

[0057] High space utilization: The screw mechanism is small in size and suitable for installation in confined spaces.

[0058] Standardization: Easy component integration, supports quick replacement and expansion.

[0059] IV. Laser Section

[0060] 1. Ultraviolet laser generator

[0061] - Solid-state ultraviolet lasers: typically employ Nd:YAG crystals with frequency triplet technology (355nm), and the pulse width is adjustable (nanosecond / picosecond level).

[0062] - High stability requirement: constant temperature control to ensure stable output energy.

[0063] 2. Ultraviolet optical system

[0064] - Specially coated lenses: High transmittance in the ultraviolet band (such as fused silica lenses), reducing energy loss.

[0065] - Beam shaping and focusing: Beam expanders, scanning galvanometers and focusing lenses achieve micron-level processing accuracy.

[0066] - Dual-head design: Independent light source enables simultaneous / independent output from both heads.

[0067] This utility model features an adjustable vertical position. An aluminum alloy handwheel is located on the top of the device, connected to an internal trapezoidal lead screw. Rotating the handwheel drives the lead screw, allowing for quick adjustment of the lens height. This enables simultaneous cutting of aluminum foil on both sides of the product at the same station, ensuring precision and consistency while saving space. It offers the following advantages: clean and consistent cutting surface for wire aluminum foil; adjustable cutting size (via program); high efficiency with dual heads; extended lifespan of traditional aluminum foil cutting tools; and good versatility, adaptable to different sizes within the same product series.

[0068] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
