Description

Technical Field

[0001] The present application relates to the technical field of cable cutting equipment, and in particular to an aluminum foil laser cutting device. Background Art

[0002] The wire harness is a key connector used to connect various components in the machine. During the processing, it generally goes through processes such as cutting, peeling, terminal crimping, and packaging.

[0003] At present, our company has developed and produced a multi-core power cord peeling device with patent announcement number CN219535453U, which includes: a base; a positioning assembly placed on the base, a driving mechanism positioning assembly including a wire slot for placing the power cord and a positioning block arranged at the end of the wire slot; a clamping assembly placed on the base, the driving mechanism clamping assembly is used to clamp a separate core wire, a stripping assembly; a driving mechanism, the driving mechanism is used to drive the stripping assembly to reciprocate along the length direction of the power cord.

[0004] The above peeling device is a mechanical cutting device, and the aluminum foil itself is of high hardness, which causes the blade of the above cutter to be easily worn, resulting in the subsequent aluminum foil being unable to be cut neatly. Therefore, our company's current processing method is to first use the above peeling device to remove the outer plastic soft skin, and then perform laser cutting on the exposed aluminum foil to complete the peeling step.

[0005] At present, the traditional laser cutting is to fix the wire, and the upper and lower laser heads cut two lines, so that the aluminum foil is cut. However, when the diameter of the wire increases, the depth increases, which makes it impossible for the laser to focus effectively and cut the aluminum foil uniformly. If the power is increased, the internal wire core may be accidentally cut. Utility Model Content

[0006] In order to solve the above technical problems, the present application provides an aluminum foil laser cutting device, which has the advantages of ensuring that a large volume of aluminum foil can be cut evenly and ensuring product quality.

[0007] In order to achieve the above object, the technical solution of the utility model is as follows:

[0008] An aluminum foil laser cutting device comprises a bottom plate, a laser cutting head is arranged on the bottom plate, a fixing component for positioning a wire harness and a clamping and rotating mechanism for clamping and rotating a wire harness end are arranged below the laser cutting head;

[0009] The clamping and rotating mechanism comprises a positioning clamping component for clamping the wiring harness terminal and a moving driving component for driving the clamping component to move horizontally and rotate.

[0010] To implement the above technical solution, the wire harness is first fixed by a fixing assembly, and then the end of the wire harness is clamped by a clamping and rotating mechanism and rotated, thereby driving the wire harness terminal to rotate. That is, when the laser cutting head is cutting, the wire harness terminal can be driven to rotate by the clamping and rotating mechanism, so that the circumferential side of the aluminum foil on the wire harness can be cut uniformly in the circumferential direction by the same laser cutting head, thereby ensuring that a large volume of aluminum foil can be cut uniformly, and the number of laser heads can be saved, thereby reducing manufacturing costs; the fixing assembly fixes the wire harness to prevent the wire harness from rotating as a whole, resulting in the occurrence of rear end winding.

[0011] As a preferred solution of the present application, the positioning clamping assembly includes a thumb cylinder, two output ends of the thumb cylinder are provided with V-shaped claws arranged opposite to each other, and the thumb cylinder is provided with an abutment positioning plate for the end of the wire harness to abut.

[0012] To implement the above technical solution, the end of the wire harness is abutted against the abutment positioning plate to position the wire harness in the axial direction, thereby ensuring the length of the laser-cut aluminum foil, and then the two V-shaped claws are driven by the thumb cylinder to approach each other to clamp the wire harness, thereby completing the clamping and fixing of the peripheral side of the wire harness terminal.

[0013] As a preferred solution of the present application, two pairs of V-shaped claws are provided.

[0014] The above technical solution is implemented to prevent the end of the wire harness from being unable to rotate when the mobile driving member drives the rotation.

[0015] As a preferred solution of the present application, two positioning and clamping assemblies are provided.

[0016] The above technical solution is implemented so that the two positioning and clamping components can clamp the two ends of the wire harness at the same time, thereby achieving that the aluminum foil at the two ends of the wire harness can be synchronously cut by the laser head at the same time, thereby improving efficiency.

[0017] As a preferred solution of the present application, the mobile driving component includes a horizontal slide rail arranged on a base plate, a bracket slidably arranged on the horizontal slide rail, and a pushing cylinder for pushing the bracket to move back and forth along the horizontal slide rail, the bracket is provided with a rotating shaft corresponding to the positioning clamping assembly one by one, a fixed plate is fixed on the rotating shaft, the positioning clamping assembly is arranged on the fixed plate, and the bracket is provided with a driving motor for driving the rotating shaft to rotate.

[0018] To implement the above technical solution, when the wiring harness is placed on the fixed assembly, the cylinder is pushed to drive the bracket to move toward the fixed part, so that the abutment positioning plate abuts against the end of the wiring harness terminal, and the thumb cylinder drives the V-shaped claws to approach each other, thereby clamping the end of the wiring harness, and then the drive motor is turned on to drive the thumb cylinder to rotate, thereby achieving the effect of driving the end of the wiring harness to rotate.

[0019] As a preferred solution of the present application, the fixing assembly includes a vertically arranged finger cylinder, and two output ends of the finger cylinder are provided with oppositely arranged wire clamping blocks.

[0020] The above technical solution is realized by driving the two wire clamping blocks closer to each other through the finger cylinder, thereby clamping the wire harness.

[0021] As a preferred solution of the present application, two fixing components are provided.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. First, fix the wire harness through the fixing assembly, and then clamp the end of the wire harness through the clamping and rotating mechanism and rotate it, so as to drive the wire harness terminal to rotate. That is, when the laser cutting head is cutting, the wire harness terminal can be driven to rotate through the clamping and rotating mechanism, so that the circumferential side of the aluminum foil on the wire harness can be cut uniformly by the same laser cutting head, thereby ensuring that a large volume of aluminum foil can be cut uniformly, and the number of laser heads can be saved, thereby reducing manufacturing costs;

[0024] 2. Place the end of the wire harness against the abutment positioning plate to position the wire harness in the axial direction, thereby ensuring the length of the laser-cut aluminum foil. Then, use the thumb cylinder to drive the two V-shaped claws closer to each other to clamp the wire harness, thereby completing the clamping and fixing of the peripheral side of the wire harness terminal.

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application embodiment discloses an aluminum foil laser cutting device. Figure 1 The aluminum foil laser cutting device includes a base plate 1, on which a laser cutting head 2 is arranged, and below the laser cutting head 2, a fixing component 3 for positioning the wire harness and a clamping and rotating mechanism 4 for clamping and rotating the end of the wire harness are arranged. That is, after the wire harness is first fixed by the fixing component 3, the end of the wire harness is clamped by the clamping and rotating mechanism 4 and rotated, thereby driving the wire harness terminal to rotate, that is, when the laser cutting head 2 is cutting, the wire harness terminal can be driven to rotate by the clamping and rotating mechanism 4, so that the circumferential side of the aluminum foil on the wire harness can be cut uniformly in the circumferential direction by the same laser cutting head 2, thereby ensuring that a large volume of aluminum foil can be cut uniformly, and the number of laser heads can be saved, thereby reducing manufacturing costs. The fixing component 3 fixes the wire harness to prevent the wire harness from rotating as a whole, resulting in the occurrence of rear end winding.

[0031] The clamping and rotating mechanism 4 comprises a positioning clamping assembly 41 for clamping the wiring harness terminal and a moving driving assembly 42 for driving the clamping assembly to move horizontally and rotate.

[0032] The positioning clamping assembly 41 includes a thumb cylinder 411, and two output ends of the thumb cylinder 411 are provided with V-shaped claws 412 arranged opposite to each other. The thumb cylinder 411 is provided with a butting positioning plate 413 for the end of the wire harness to butt against, that is, the end of the wire harness is butted against the butting positioning plate 413 to position the axial direction of the wire harness, thereby ensuring the length of the laser cutting aluminum foil. Then, the thumb cylinder 411 drives the two V-shaped claws 412 to approach each other to clamp the wire harness, thereby completing the clamping and fixing of the peripheral side of the wire harness terminal. In order to ensure the stability of the clamping, two pairs of V-shaped claws 412 are provided to prevent the end of the wire harness from being unable to rotate when the moving drive member drives the rotation.

[0033] Two positioning and clamping assemblies 41 are provided, so that the two positioning and clamping assemblies 41 can clamp the two ends of the wire harness at the same time, thereby achieving that the aluminum foil at the two ends of the wire harness can be synchronously cut by the laser head at the same time, thereby improving efficiency.

[0034] The mobile driving member includes a horizontal slide rail 421 arranged on the bottom plate 1, a bracket 422 is arranged on the horizontal slide rail 421, and a push cylinder 423 is arranged on the bottom plate 1 for pushing the bracket 422 to move along the horizontal slide rail 421, that is, the bracket 422 is driven to move along the horizontal slide rail 421 by the push cylinder 423, so that the bracket 422 is close to or away from the fixed component 3. The bracket 422 is provided with a rotating shaft 424 corresponding to the positioning clamping component 41, and each rotating shaft 424 is fixed with a fixing plate 425, and the thumb cylinder 411 is fixedly installed on the fixing plate 425, so that the positioning clamping component 41 can rotate with the rotating shaft 424 as a whole, and a driving motor 426 for driving the rotating shaft 424 to rotate is arranged on the bracket 422, and the driving motor 426 drives the rotating shaft 424 to rotate through the gear toothed belt transmission component, and a transmission mechanism 427 for driving the synchronous rotation is arranged between the rotating shafts 424, and the transmission mechanism 427 in this embodiment is a gear toothed belt. That is, when the wire harness is placed on the fixing assembly 3, the push cylinder 423 drives the bracket 422 to move toward the fixing part, so that the abutting positioning plate 413 abuts against the end of the wire harness terminal, and the thumb cylinder 411 drives the V-shaped claws 412 to approach each other, thereby clamping the end of the wire harness. Then, the driving motor 426 is turned on to drive the thumb cylinder 411 to rotate, thereby achieving the effect of driving the end of the wire harness to rotate.

[0035] The fixing assembly 3 and the clamping assembly are arranged one by one to ensure the fixing effect of the wire harness. In this embodiment, two fixing assemblies 3 are arranged. The fixing assembly 3 includes a finger cylinder 31 arranged vertically, and two output ends of the finger cylinder 31 are provided with relatively arranged wire clamping blocks 32. A vertical plate 5 is arranged on the bottom plate 1. The finger cylinder 31 is fixed on the vertical plate 5, that is, the finger cylinder 31 drives the two wire clamping blocks 32 to approach each other, thereby clamping the wire harness. The wire clamping block 32 is set to silicone so that it can be deformed to tightly wrap the wire harness, thereby ensuring the stability of the clamping and preventing the wire harness from being clamped.

[0036] The implementation principle of an aluminum foil laser cutting device in the embodiment of the present application is as follows: first, the wire harness is fixed by the fixing component 3, and then the end of the wire harness is clamped by the clamping rotating mechanism 4 and rotated, thereby driving the wire harness terminal to rotate, that is, when the laser cutting head 2 is cutting, the wire harness terminal can be driven to rotate by the clamping rotating mechanism 4, so that the circumferential side of the aluminum foil on the wire harness can be cut uniformly by the same laser cutting head 2, thereby ensuring that a large volume of aluminum foil can be cut uniformly, and the number of laser heads can be saved, thereby reducing manufacturing costs. The fixing component 3 fixes the wire harness to prevent the wire harness from rotating as a whole, resulting in the occurrence of rear end winding.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
