Description

Technical Field

[0001] This application relates to the field of wire harness processing, and in particular to an automated wire stripping device. Background Technology

[0002] During the processing of electronic wire harnesses, the cut electronic wire harnesses need to be stripped at the ends to remove the outer sheath, making it easier to install terminals at the ends of the electronic wire harnesses later.

[0003] Existing automated wire stripping devices typically perform cutting and stripping at the same station, usually using a continuous wire harness conveyor system. This conveying primarily relies on rollers for clamping and transporting the wire harness. Some wire cutting devices incorporate limit switches on the rollers to restrict the wire harness movement and improve conveying stability.

[0004] However, when using rollers to hold and transport wire harnesses, the harnesses are prone to shifting during transport, which can affect the accuracy of wire stripping to some extent. While setting limiting parts on the rollers can limit the shift, it is not applicable to wire harnesses of different diameters, affecting the flexibility of the wire stripping device. Utility Model Content

[0005] In order to enable the wire stripping device to be applicable to wire harnesses of different diameters while maintaining the accuracy of the wire stripping device, this application provides an automated wire stripping device.

[0006] The automated wire stripping device provided in this application adopts the following technical solution: An automated wire stripping device includes a frame, a conveyor belt, a mounting block, a drive unit, a clamping assembly, and a stripping assembly. The conveyor belt is mounted on the frame, the mounting block is fixed to the conveyor belt, and both the clamping assembly and the drive unit are mounted on the mounting block. The clamping assembly is used to clamp a wire harness, and the drive unit is used to drive the clamping assembly to move along the width direction of the conveyor belt. The stripping assembly is located on one side of the conveyor belt and is used to strip the insulation from the ends of the wire harness.

[0007] By adopting the above technical solution, the mounting block is moved by the conveyor belt, the clamping component on the mounting block can clamp wire harnesses of different diameters, the driving component can drive the clamping component to move in the width direction of the conveyor belt, which is convenient for adjusting the position of the wire harness, and the wire stripping component can strip the wire harness ends, thereby ensuring the accuracy of the wire stripping process, and also making this device suitable for wire harnesses of different diameters.

[0008] Optionally, the clamping assembly includes a first clamping block and a second clamping block; the first clamping block includes a first force-receiving part and a first clamping part, and the second clamping block includes a second force-receiving part and a second clamping part; the first force-receiving part and the second force-receiving part are connected by a cylinder jaw; the first clamping part and the second clamping part are used to cooperate in clamping the wire harness.

[0009] By adopting the above technical solution, a torsion spring is used to connect the first force-bearing part and the second force-bearing part. When the torsion spring is in its original shape, the first clamping part and the second clamping part abut against each other, thereby achieving elastic clamping of wire harnesses of different diameters, preventing the wire harnesses from shifting during the transportation process, improving the accuracy of wire stripping, and enhancing the flexibility of the wire stripping device.

[0010] Optionally, the first clamping part has a receiving groove, and the second clamping part has a protruding abutting part. The receiving groove and the abutting part are disposed opposite to each other, and the abutting part extends into the receiving groove.

[0011] By adopting the above technical solution, the receiving groove is used to hold the wire harness, and the abutting part is used to abut the wire harness, thereby forming an effective clamp for wire harnesses of different diameters and reducing the possibility of the wire harness shaking after being clamped.

[0012] Optionally, the mounting block is provided with a first partition, and the clamping assembly is provided with a second partition; the second partition is located between the first partition and the conveyor belt, and a buffer spring is provided between the second partition and the first partition.

[0013] By adopting the above technical solution, a buffer spring is provided between the first partition of the mounting block and the second partition of the clamping assembly, which can buffer the clamping assembly, reduce the impact of vibration and impact on clamping and wire stripping operations, and improve the stability of the device and the wire stripping effect.

[0014] Optionally, the wire stripping assembly includes a mounting base, a blade base, a movable blade, a drive cylinder, and a drive motor; the mounting base is mounted on the frame, the blade base is rotatably connected to the mounting base, the drive motor is mounted on the mounting base, and the drive motor is used to drive the blade base to rotate relative to the mounting base; the drive cylinder is mounted on the blade base, and the drive cylinder is used to drive the blade to move radially along the blade base.

[0015] By adopting the above technical solution, the blade base is driven by the drive motor to rotate relative to the mounting base, and the blade is driven by the drive cylinder to move radially along the blade base. This allows the blade to perform flexible and precise stripping of the ends of the electronic wire harness, avoiding the problem of wire harness offset affecting the stripping accuracy when using rollers to clamp and transmit the wire harness.

[0016] Optionally, the blade has a "V" shaped cutting edge.

[0017] Optionally, the wire stripping assembly further includes a fixing clamp disposed between the blade and the conveyor belt, the fixing clamp being used to clamp the wire harness.

[0018] By adopting the above technical solution, when stripping the wire harness, the wire harness is clamped a second time using a fixed clamp to further correct the position of the wire harness; in addition, after stripping is completed, the clamping assembly is moved a distance closer to the conveyor belt by the drive component, and the outer shell part of the wire harness to be stripped is clamped by the fixed clamp. Then, the clamping assembly is reset to the direction of the conveyor belt by the drive component, so that the outer shell of the wire harness that has been cut off is stripped by the fixed clamp.

[0019] Optionally, a container is provided below the wire stripping assembly for holding the stripped outer shell of the wire harness.

[0020] By adopting the above technical solution, the automated wire stripping device uses a conveyor belt to transport the wire harness, the drive unit drives the clamping assembly to move, the wire stripping assembly strips the insulation from the ends of the wire harness, and a container is set below the wire stripping assembly to hold the stripped outer shell of the wire harness, preventing the outer shell from scattering randomly and affecting the working environment and equipment operation.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a drive unit and a clamping assembly on the conveyor belt, the clamping assembly is used to clamp the wire harness to ensure the precise positioning of the wire harness. At the same time, the wire cutting device is suitable for wire harnesses of different diameters. The drive unit drives the clamping assembly to move the cutting point of the wire harness to below the wire stripping assembly, thereby automating the wire stripping device. 2. By setting a first partition and a second partition, and setting a buffer spring between the first partition and the second partition, the clamping assembly is buffered and protected during the start and stop of the drive component; 3. The wire stripping assembly includes a mounting base, a blade base, a movable blade, a drive cylinder, and a drive motor. The drive motor drives the blade base to rotate, and the drive cylinder drives the blade to move radially along the blade base. The blade edge is "V" shaped, which allows it to cut into the outer sheath of the wire harness more effectively, thus improving the efficiency and effect of wire stripping.

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] This application discloses an automated wire stripping device.

[0031] Reference Figures 1 to 6 An automated wire stripping device includes a frame 1, a conveyor belt 2, a mounting block 3, a drive unit 4, a clamping assembly 5, and a wire stripping assembly 6.

[0032] The conveyor belt 2 is mounted on the frame 1, and the mounting block 3 is fixed to the conveyor belt 2. The clamping component 5 and the driving component 4 are both mounted on the mounting block 3. The clamping component 5 is used to clamp the wire harness, and the driving component 4 is used to drive the clamping component 5 to move along the width direction of the conveyor belt 2. The wire stripping component 6 is located on one side of the conveyor belt 2 and is used to strip the end of the wire harness. This achieves the effect of stable wire harness conveying and precise wire stripping. The cooperation between the conveyor belt 2 and the clamping component 5 avoids the problem of wire harness deviation when the roller clamps the wire harness. At the same time, the clamping component 5 can clamp wire harnesses of different diameters, ensuring the flexibility of the wire stripping device.

[0033] Specifically, the clamping assembly 5 includes a first clamping block 51 and a second clamping block 52. The first clamping block 51 includes a first force-receiving part 512 and a first clamping part 511, and the second clamping block 52 includes a second force-receiving part 522 and a second clamping part 521. The first force-receiving part 512 and the second force-receiving part 522 are connected by a cylinder gripper. Under normal conditions, the first clamping part 511 and the second clamping part 521 abut against each other, and the first clamping part 511 and the second clamping part 521 are used to clamp the wire harness.

[0034] The first clamping part 511 is typically a block structure, and its material can be a high-hardness plastic or metal, such as aluminum alloy, to ensure that it will not easily deform when clamping the wire harness. The first force-bearing part 512 and the first clamping part 511 can be integrally molded to ensure structural stability. The second clamping block 52 is similar to the first clamping block 51; the second force-bearing part 522 and the second clamping part 521 can also be integrally molded, and the material can also be aluminum alloy. The torsion spring serves to keep the first clamping part 511 and the second clamping part 521 in abutting state. When an external force is applied to the first force-bearing part 512 and the second force-bearing part 522, the torsion spring will deform, causing the first clamping part 511 and the second clamping part 521 to separate, facilitating the insertion or removal of the wire harness.

[0035] When the first clamping part 511 and the second clamping part 521 cooperate to clamp the wire harness, the clamping force is provided by the elastic force of the torsion spring, which can adapt to wire harnesses of different diameters. When the wire harness diameter is small, the deformation of the torsion spring is small, but it can still provide sufficient clamping force; when the wire harness diameter is large, the torsion spring will deform further, causing the first clamping part 511 and the second clamping part 521 to separate at a certain angle, while still being able to stably clamp the wire harness. This structure makes the clamping assembly 5 highly versatile and improves the flexibility of the wire stripping device.

[0036] Furthermore, the first clamping part 511 has a receiving groove 513, and the second clamping part 521 has a protruding abutment part 523, with the receiving groove 513 and the abutment part 523 positioned opposite each other. Thus, the receiving groove 513 accommodates the wire harness, and the abutment part 523 effectively limits the wire harness, ensuring clamping stability without damaging it. The groove walls of the receiving groove 513 and the abutment part 523 can be provided with anti-slip textures, such as fine serrated textures, to enhance friction and prevent the wire harness from slipping during clamping. These anti-slip textures can also be replaced with rubber pads, which have good elasticity and friction, and also provide an anti-slip effect.

[0037] Furthermore, the mounting block 3 is provided with a first partition 31, and the clamping assembly 5 is provided with a second partition 32. The second partition 32 is located between the first partition 31 and the conveyor belt 2, and a buffer spring 33 is provided between the second partition 32 and the first partition 31. The first partition 31 is usually a protruding block structure on the mounting block 3, and its material can be metal, such as carbon steel, to ensure sufficient strength. The second partition 32 can be an extension on the clamping assembly 5, and its material can also be carbon steel. The function of the buffer spring 33 is to buffer the clamping assembly 5 when it is subjected to external impact, protecting the clamping assembly 5 and the wire harness. The elastic coefficient of the buffer spring 33 needs to be selected according to the actual use to achieve the best buffering effect. The buffer spring 33 can also be replaced by a rubber buffer block, which has good buffering performance and is easy to install.

[0038] Specifically, the wire stripping assembly 6 includes a mounting base 61, a blade base 62, a movable blade 63, a drive cylinder 64, and a drive motor 65. The mounting base 61 is mounted on the frame 1, the blade base 62 is rotatably connected to the mounting base 61, and the drive motor 65 is mounted on the mounting base 61. The drive motor 65 is used to drive the blade base 62 to rotate relative to the mounting base 61.

[0039] A drive cylinder 64 is mounted on the blade base 62 and is used to drive the blade to move radially along the blade base 62. The mounting base 61 is typically a plate-like structure, and its material can be cast iron to ensure sufficient stability and load-bearing capacity. The blade base 62 is generally a disc-like structure, and its material can be stainless steel, which has good corrosion resistance and strength. The movable blade 63 can be made of high-speed steel, which has high hardness and good wear resistance.

[0040] When stripping the wire, first start the drive cylinder 64 to make the movable blade 63 cut one side of the wire harness sheath, then start the drive motor 65 to drive the blade base 62 to rotate, and cut off the wire harness sheath by circumferential cutting.

[0041] The movable blade 63, under the combined action of the drive motor 65 and the drive cylinder 64, can flexibly adjust its position and angle to strip wire harnesses of different specifications and orientations. By rotating the blade base 62, the movable blade 63 can approach the wire harness from different directions; by driving the movable blade 63 radially with the drive cylinder 64, the depth to which the blade cuts into the wire harness sheath can be controlled, thereby improving the accuracy and efficiency of wire stripping.

[0042] Furthermore, the movable blade 63 has a "V"-shaped cutting edge. This "V"-shaped design makes it easier for the movable blade 63 to cut into the wire harness sheath, reducing cutting resistance. The tip of the "V"-shaped blade can more precisely align with the wire harness sheath, improving cutting accuracy. Simultaneously, the "V"-shaped blade can separate the sheath to both sides during cutting, facilitating peeling. The "V"-shaped blade can also be replaced with a "U"-shaped blade, which achieves similarly good cutting and peeling results, but differs in the cutting method and the distribution of cutting force.

[0043] When the movable blade 63 strips the wire harness, the "V"-shaped blade can quickly cut into the outer sheath of the wire harness, and then gradually peel off the outer sheath as the blade rotates and moves. This blade shape improves the efficiency and quality of wire stripping and reduces damage to the internal conductors of the wire harness.

[0044] Furthermore, the wire stripping assembly 6 also includes a retaining clamp 66, which is disposed between the blade and the conveyor belt 2. The retaining clamp 66 is used to clamp the wire harness. The retaining clamp 66 is typically a pair of clamping plates, and the material can be plastic or metal, such as copper alloy. The retaining clamp 66 can be fixed to the wire stripping assembly 6 by bolts or other connectors.

[0045] During wire stripping, the fixing clamp 66 first clamps the wire harness to maintain its stable position. This prevents the wire harness from moving or shaking during stripping, improving stripping accuracy. The clamping force of the fixing clamp 66 can be controlled by adjusting the tightness of the bolts to accommodate wire harnesses of different diameters. The fixing clamp 66 can also be replaced by a pneumatic gripper, which allows for easier and faster clamping and releasing.

[0046] Below the wire stripping assembly 6 is a holding box 7, which is used to hold the stripped outer shell of the wire harness. The holding box 7 is typically a box-shaped structure, and the material can be plastic or metal, such as galvanized steel sheet. The holding box 7 can be mounted on the rack 1 via slide rails or other means for easy disassembly and cleaning.

[0047] When the outer sheath of the wire harness is stripped, it falls into the collection box 7. The collection box 7 collects the stripped sheath, preventing it from scattering on the workbench or floor and maintaining a clean working environment. Regularly cleaning the collection box 7 ensures the continuous operation of wire stripping.

[0048] The implementation principle of an automated wire stripping device is as follows: This automated wire stripping device transports wire harnesses via a conveyor belt 2, avoiding the problem of wire harness misalignment during traditional roller clamping and transport, thus improving the stability of wire harness transport. The clamping assembly 5 uses a first clamping block 51 and a second clamping block 52 connected by torsion springs, which can adapt to wire harnesses of different diameters, improving the flexibility of the device. The wire stripping assembly 6 controls the rotation and radial movement of the movable blade 63 through a drive motor 65 and a drive cylinder 64, and in conjunction with the "V"-shaped blade, can accurately strip wire harnesses of different specifications. The fixed clamping component 66 ensures the stability of the wire harness during the stripping process, while the container 7 maintains a clean working environment. The entire device has a reasonable structure, is easy to operate, and effectively improves the accuracy and efficiency of wire stripping.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
