Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting device for high-speed cable processing. Background Technology

[0002] High-speed cables are key components in modern communication, data transmission, and power transmission. They are characterized by high transmission rates, low signal loss, and strong anti-interference capabilities, and are widely used in 5G communication, data centers, automotive electronics, and industrial automation.

[0003] High-speed cables have a complex structure, including multiple layers of materials such as multi-strand conductors, insulation layers, shielding layers, and outer sheaths. They need to be stripped before use. Laser cutting technology has the advantages of high precision and high efficiency and is often used for cutting and stripping high-speed cables.

[0004] The core purpose of laser cutting and stripping is to peel off the outer sheath or insulation layer of high-speed cables to expose the internal conductors. Since high-speed cables are usually processed in multiple bundles (such as 8 cores, 12 cores or more), in order to ensure that the spacing between each core is consistent and to avoid signal crosstalk or assembly difficulties caused by uneven spacing, multiple bundles of cores are usually arranged side by side and fixed with tape to maintain the relative position between the cores. After cutting, the tape is peeled off one by one. This process takes a lot of time. The application and removal of tape becomes the bottleneck of the entire processing flow, significantly reducing production efficiency and making it difficult to meet the needs of large-scale production. Summary of the Invention

[0005] In view of this, the present invention provides a laser cutting device for high-speed cable processing, which can overcome the disadvantages of using tape to fix the wire cores in order to maintain the relative position between the wire cores, and then tearing off the tape one by one after the cutting is completed. This process consumes a lot of time, significantly reduces production efficiency, and makes it difficult to meet the needs of large-scale production.

A torsion spring is connected between the support plates and the rotating blocks. Two vertical plates are connected to the top of the slide plate, and two push plates are connected to each vertical plate. The push plates are used to push the rotating blocks, causing the rotating blocks to rotate. The rotating blocks drive the stripping plates to rotate, and the stripping plates clamp the insulation layer cut off from the wire core.

[0011] Furthermore, it also includes an air intake mechanism, which includes a housing, an air pipe, and a purification component. The mounting plate has an installation port in the middle, and the housing is connected inside the installation port.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0031] refer to Figures 1-5 A laser cutting device for high-speed cable processing includes a mounting box 1, a mounting plate 2, an electric guide rail 3, a connecting frame 4, a laser cutter 5, a lead screw motor 6, a sliding plate 7, a notched ring 8, a rotating plate 9, a clamping mechanism, and a flipping mechanism. The mounting box 1 is bolted to the top of the mounting plate 2. The electric guide rail 3 is bolted to the top right side of the top of the mounting plate 2. The top of the slider of the electric guide rail 3 is bolted to the connecting frame 4. The laser cutter 5 is bolted to the upper part of the connecting frame 4. The lead screw motor 6 is mounted on both the front and rear sides of the top of the mounting plate 2. The lead screw of the lead screw motor 6 is rotatably connected to the left side of the electric guide rail 3. The sliding plate 7 is slidably connected to the top middle of the mounting plate 2. The lead screw of the lead screw motor 6 and the sliding plate 7 are threaded together. The notched ring 8 is rotatably connected to the left middle of the sliding plate 7. The rotating plate 9 is connected to the bottom of the notched ring 8. The rotating plate 9 has evenly spaced dividing grooves 10 on its top. The clamping mechanism is used to clamp the core of the high-speed cable, and the flipping mechanism is used to flip the core of the high-speed cable.

[0032] refer to Figure 3 and Figure 4The clamping mechanism includes a clamping plate 111 and a first motor 113. The top of the rotating plate 9 is rotatably connected to the clamping plate 111. The bottom of the clamping plate 111 is evenly spaced with receiving grooves 112. The inside of the receiving grooves 112 and the inside of the partition grooves 10 are both lined with a layer of silicone to prevent the rotating plate 9 and the clamping plate 111 from damaging the core of the high-speed cable. The first motor 113 is bolted to the right side of the rotating plate 9. The output shaft of the first motor 113 is connected to the clamping plate 111.

[0033] refer to Figure 5 The flipping mechanism includes an arc-shaped rack 121, a second motor 122, and a gear 123. The arc-shaped rack 121 is installed at the bottom of the notch ring 8. The second motor 122 is installed on the front left side of the slide plate 7 by bolts. The output shaft of the second motor 122 is connected to the gear 123 by a key. The gear 123 meshes with the arc-shaped rack 121.

[0034] refer to Figure 6 It also includes a cleaning mechanism, which includes a mounting frame 131, a cleaning brush 132, and a third motor 133. The mounting frame 131 is bolted to the right side of the rotating plate 9. The cleaning brush 132 is rotatably connected to both the upper and lower parts of the mounting frame 131. The third motor 133 is bolted to both the upper and lower parts of the mounting frame 131. The output shaft of the third motor 133 is connected to the front end of the cleaning brush 132 via a coupling.

[0035] refer to Figure 7 and Figure 8 It also includes a peeling mechanism, which comprises a support plate 141, a rotating shaft 142, a peeling plate 143, a rotating block 144, a torsion spring 145, a vertical plate 146, and a push plate 147. Two support plates 141 are bolted to the top right side of the mounting plate 2. The two support plates 141 are arranged opposite each other front to back. Two rotating shafts 142 are rotatably connected to the two support plates 141. The two rotating shafts 142 are arranged vertically opposite each other, and a peeling plate is connected to the middle of each rotating shaft 142. 143, Rotating blocks 144 are connected to both ends of the rotating shaft 142. Torsion springs 145 are fitted on both the front and rear of the rotating shaft 142. The two ends of the torsion springs 145 are connected to the support plate 141 and the rotating block 144 respectively. Vertical plates 146 are bolted to both the front and rear sides of the top right side of the slide plate 7. Two push plates 147 are bolted to the side of the two vertical plates 146 that are close to each other. The two push plates 147 on the same vertical plate 146 are arranged vertically opposite each other.

[0036] The operator controls the output shaft of the first motor 113 to rotate, causing the clamping plate 111 to rotate upwards and open. Then, the high-speed cable core is placed into the separating groove 10, which separates the core. The core is then pushed to the right, moving it between the two cleaning brush rollers 132. The operator then controls the output shaft of the third motor 133 to rotate, causing the cleaning brush rollers 132 to rotate and feed the high-speed cable core to the right, placing it directly below the laser cutter 5. Finally, the operator controls the output shaft of the first motor 113 to rotate in the opposite direction, causing the clamping plate 111 to rotate downwards and clamp the high-speed cable core. No tape is needed for securing the core, and no further fixation is required. Removing the tape saves time and improves production efficiency to meet the needs of large-scale production. The receiving slot 112 can accommodate the core of the high-speed cable. Then, the electric guide rail 3 drives the connecting frame 4 to move back and forth, which in turn drives the laser cutter 5 to move back and forth. The laser cutter 5 laser-cuts the insulation layer on the core. After one side is cut, the output shaft of the second motor 122 is rotated, driving the gear 123 to rotate. The gear 123 drives the arc-shaped rack 121 to rotate, which in turn drives the notched ring 8 to rotate. The notched ring 8 drives the rotating plate 9 to rotate, which in turn drives the core of the high-speed cable to rotate 180 degrees, flipping the core so that the other side can be laser-cut. After cutting on both sides, the control screw motor 6 drives the slide plate 7 to move to the left. The slide plate 7 drives the vertical plate 146 and the push plate 147 to move to the left. The push plate 147 pushes the rotating block 144, causing the rotating block 144 to rotate. The torsion spring 145 deforms, and the rotating block 144 drives the rotating shaft 142 to rotate. The rotating shaft 142 drives the stripping plate 143 to rotate. The two stripping plates 143 rotate towards each other, which can clamp the insulation layer cut off from the wire core. At the same time, the leftward movement of the slide plate 7 can also drive the rotating plate 9 to move to the left, thereby driving the wire core of the high-speed cable to move to the left, so that the stripping plate 143 can peel off the insulation layer cut off from the wire core. The automatic stripping of the cut insulation layer has a higher degree of automation. This improves production efficiency. Then, the output shaft of the first motor 113 is controlled to rotate, causing the clamping plate 111 to rotate upwards, loosening the high-speed cable core. The high-speed cable core is then pulled to the left, removing it from the separator groove 10. During laser cutting, the insulation layer on the core may be excessively ablated, forming carbonized black edges or molten material that adheres to the conductor surface. This debris may affect the conductor's conductivity. Therefore, the output shaft of the third motor 133 is controlled to rotate, causing the cleaning brush roller 132 to rotate. The cleaning brush roller 132 removes the debris from the conductor surface, ensuring the conductor's conductivity and the reliability of the connection. Finally, the lead screw motor 6 is controlled to move the slide plate 7 to the right, which in turn moves the push plate 147 to the right.The push plate 147 and the rotating block 144 disengage. Under the action of the torsion spring 145, the rotating block 144 rotates in the opposite direction. The rotating block 144 drives the stripping plate 143 to rotate in the opposite direction. The two stripping plates 143 rotate in a direction away from each other, loosening the insulation layer cut off from the wire core.

[0037] refer to Figure 9 It also includes an air intake mechanism, which includes a housing 152, an air pipe 153, and a purification component. The mounting plate 2 has an installation port 151 in the middle. The housing 152 is bolted to the left side of the installation port 151. The bottom of the housing 152 is connected to the air pipe 153, which passes through the front side of the mounting box 1. The purification component is used to purify the harmful gases generated by laser cutting.

[0038] refer to Figure 9 The purification component includes a filter element 154 and a connector 155. The front end of the air tube 153 is connected to the filter element 154 by a thread, and the front end of the filter element 154 is connected to the connector 155.

[0039] refer to Figure 10 and Figure 11 It also includes a collection mechanism, which includes a support block 161, a U-shaped plate 162, a collection bag 163 and a sealing plate 165. The support block 161 is bolted to both the front and rear sides of the box body 152. The U-shaped plate 162 is placed on the two support blocks 161. The collection bag 163 is connected to the bottom of the U-shaped plate 162. An opening 164 is opened on the left side of the box body 152. The sealing plate 165 is bolted to the left side of the box body 152.

[0040] Harmful gases are generated during laser cutting. Workers can connect connector 155 to an air pump to draw the harmful gases into the chamber 152. The harmful gases are then discharged through air pipe 153 to prevent them from spreading. Filter element 154 can purify the harmful gases to prevent environmental pollution. Filter element 154 is removable for easy replacement. At the same time, debris cleaned by cleaning brush 132 is also drawn into the chamber 152 and falls into collection bag 163 for collection and subsequent centralized processing. Sealing plate 165 can be opened, and collection bag 163 can be removed through opening 164 to process the debris inside.
