Technical Field

[0002] An LED (Light Emitting Diode) is a semiconductor device that converts electrical energy into light. It boasts high luminous efficiency, low energy consumption, long lifespan, energy-saving features, and fast response times, making it widely used in various applications. An LED lamp consists of two wiring harnesses and LED lamp beads. The two wiring harnesses connect to the positive and negative terminals of the LED beads, respectively. The end of the wiring harness away from the LED beads can be connected to components such as circuit boards.

[0003] In the prior art, LED lamp beads and wiring harnesses are usually welded using a welding machine. During welding, the lamp beads and wiring harness need to be manually docked together, and then welded together using welding parts. This has technical problems such as low welding efficiency and low degree of automation.

[0004] In addition, when multiple LED lamps are used together, a wire cutting mechanism needs to be set up at the front station of the welding machine. Although the wire cutting mechanism can remove multiple parallel wire harnesses at a time, the lengths of the multiple wire harnesses removed by the existing wire cutting mechanism are equal; and the end of the wire harness away from the LED lamp beads is connected to the circuit board wire harness at a different position. When the equal-length wire harness is connected to the circuit board, the wire stripping needs to be done again, resulting in a technical problem of inconvenient operation in the connection between the wire harness and the circuit board.

[0026] Among them, the wire twisting drive member 261, the first drive member 266 and the second drive member 267 all include but are not limited to pneumatic cylinders, hydraulic cylinders and linear motors; the upper wire twisting rod 264 and the lower wire twisting rod 265 are provided with multiple twisting teeth distributed at intervals. After the upper wire twisting rod 264 and the lower wire twisting rod 265 approach each other, the first end wire core of the free wire harness 200 is twisted tightly by the twisting teeth, so that the first end wire core of the free wire harness 200 is entangled together, avoiding the first end wire core of the free wire harness 200 from being scattered, thereby facilitating the welding work of the first end wire core of the free wire harness 200.

[0027] Specifically, the cutting and stripping assembly 25 cuts and strips the baseline 100, the first upper wire stripping knife 252 and the first lower wire stripping knife 255 are in a state close to each other, and the second upper wire stripping knife 254 and the second lower wire stripping knife 257 are in a state close to each other; the first driving member 266 drives the upper wire twisting rod 264 to move downward, and the second driving member 267 drives the lower wire twisting rod 265 to move upward, and the upper wire twisting rod 264 and the lower wire twisting rod 265 are close to each other to clamp the head end of the free wire harness 200, and the wire twisting drive The movable member 261 drives the connecting rod 262 to move back and forth up and down, and the connecting rod 262 drives the upper thread-rubbing rod 264 and the lower thread-rubbing rod 265 to move back and forth left and right through the rocker 263; since the head end outer skin of the free wire harness 200 is in a free state, the upper thread-rubbing rod 264 and the lower thread-rubbing rod 265 clamp the free end outer skin of the free wire harness 200, and the left and right reciprocating movement of the upper thread-rubbing rod 264 and the lower thread-rubbing rod 265 can make the head end wire cores inside the free end outer skin be entangled together.

[0028] In this embodiment, the design of the wire twisting assembly 26 can allow the wire cores at the head end of the free wire harness 200 to be twisted together, which facilitates the welding of the wire cores at the head end of the free wire harness 200.

[0029] In one embodiment, if Figure 4 As shown, the cutting mechanism 2 further includes a receiving box 27 mounted on the lower support block 24; the receiving box 27 is located below the first lower wire stripping knife 255, the lower cutting knife 256 and the second lower wire stripping knife 257, and is used to receive the outer skin peeled off the free wire harness 200; The cutting and stripping assembly 25 further includes a wire pressing drive 258 mounted on the upper support block 23 . The output end of the wire pressing drive 258 is connected to the pressing block 251 . The wire pressing drive 258 is used to drive the pressing block 251 to move up and down.

[0030] The wire pressing drive component 258 includes but is not limited to a pneumatic cylinder, a hydraulic cylinder, and a linear motor; the pressing block 251 can be slidably mounted on the upper support block through a guide rail slider assembly, a guide rod sleeve assembly, and the like.

In addition, the wire pressing drive 258 can drive the pressing block 251 to move up and down, thereby adjusting the depth of the protrusion 2511 of the pressing block 251 inserted into the groove, thereby adjusting the length of the free wire harness 200 to be bent.

[0032] In one embodiment, if Figure 2 and Figure 7As shown, the wire cutting device also includes a wire pulling mechanism 3; the wire pulling mechanism 3 includes a wire pulling drive 31 and a wire pulling clamp 32 installed on the wire pulling drive 31; the wire pulling clamp 32 is used to clamp the tail end of the baseline 100; the wire pulling drive 31 is used to lengthen the baseline 100 through the wire pulling clamp 32.

[0033] The wire driving component 31 includes but is not limited to a pneumatic cylinder, a hydraulic cylinder, a linear motor, a screw nut assembly, etc.

[0034] Specifically, after the wire pulling clamp 32 clamps the tail end of the baseline 100, the wire pulling drive 31 drives the wire pulling clamp 32 to move in the direction away from the cutting mechanism 2. After the wire pulling mechanism 3 stretches the baseline 100 to a preset length, the cutting and stripping assembly 25 bends, cuts and strips the baseline 100. The wire pulling mechanism 3 drives the free wire harness 200 that comes down after cutting to move, so that the peeled outer skin of the free wire harness 200 can fall off; the wire stripping drive 22 then drives the upper support block and the lower support block away from each other.

[0035] In this embodiment, the design of the wire pulling mechanism 3 can cut the free wire harness 200 of a required length from the baseline 100, further improving the degree of automation of the wire cutting device.

[0037] Each of the wire drums 412 is wound with a coil of baseline 100 ; the first straightening wheel 422 can rotate in a horizontal direction, and the second straightening wheel 423 can rotate in a vertical direction.

[0038] In the process of the wire pulling mechanism 3 stretching the baseline 100 , the wire drum 412 will release the baseline 100 ; in the process of the pressing block 251 bending part of the baseline 100 , the corresponding wire drum 412 will also release the baseline 100 .

[0039] In this embodiment, when the baseline 100 moves in the vertical straightening groove, the first straightening wheel 422 can roll the baseline 100 straight from the up and down directions; when the baseline 100 moves in the horizontal straightening groove, the second straightening wheel 423 can roll the baseline 100 straight from the left and right directions, thereby ensuring the verticality of the free wire harness 200 cut by the wire cutting device.
