Description

Technical Field

[0001] This application relates to the field of wire stripping equipment technology, and in particular to a wire clamping claw and wire stripping device. Background Technology

[0002] An electric wire is a conductor that carries electric current.

[0003] The wire clamping module of a wire stripping machine is responsible for clamping the wires, and its performance affects the efficiency of the equipment and the quality of the processing. However, existing modules often have problems such as getting stuck on the wire sheath, which leads to the wire not being able to be clamped, the wire slipping and falling off, resulting in equipment downtime, waste, and the production of defective products.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

In practical applications, the first direction X, the second direction Y, and the third direction Z can point to any direction in space, as long as the intersection relationship between the two is maintained.

[0017] In some examples, the first direction X is the direction in which the clamping claws open and close, the second direction Y is the width direction of the clamping claws, and the third direction Z is the direction of wire transport.

[0018] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0019] An electric wire is a conductor that carries electric current. It consists of one or more flexible conductors, with the inner conductor responsible for carrying electricity and an outer soft sheath for corrosion and static electricity prevention. The accompanying wire stripping machine's main function is to separate the plastic sheath from the metal core of the wire, facilitating subsequent processing or connection.

[0020] The wire clamping module of the wire stripping machine is responsible for clamping the wire, and its performance affects the efficiency of the equipment and the processing quality. However, the existing wire clamping module consists of eight blades, with four blades on each of the two mating clamping sides. It often suffers from problems such as the wire sheath getting stuck and the wire clamping blocks wearing out, which leads to the wire not being able to be clamped properly, the wire slipping and easily falling off, resulting in equipment downtime and waste, the production of defective products, and the need for frequent replacement of parts, resulting in high maintenance costs.

[0021] According to the first aspect of this application, please refer to Figure 1 , Figure 2 and Figure 5This application provides a wire clamping claw for clamping an electrical wire 400. It should be noted that the wire clamping claw includes a first clamping claw 100, a second clamping claw 200, and a driving mechanism 300. The first clamping claw 100 and the second clamping claw 200 are arranged opposite each other along a first direction X. The first clamping claw 100 and the second clamping claw 200 open and close in the first direction X. When the first clamping claw 100 and the second clamping claw 200 are in the open state, the electrical wire 400 can pass through between the first clamping claw 100 and the second clamping claw 200. When the first clamping claw 100 and the second clamping claw 200 are in the closed state, the electrical wire 400 is clamped by the first clamping claw 100 and the second clamping claw 200.

[0022] The first clamp 100 includes a first clamping block 110, and the first clamping block 110 has a first clamping groove 120 on the side facing the second clamp 200. The second clamp 200 includes a second clamping block 210, and the second clamping block 210 has a second clamping groove 220 on the side facing the first clamping block 110. When the first clamp 100 and the second clamp 200 are in the open state, the wire 400 can pass through the first clamping groove 120 and the second clamping groove 220; when the first clamp 100 and the second clamp 200 are in the closed state, the wire 400 is accommodated in the first clamping groove 120 and the second clamping groove 220, and abuts against a portion of the groove wall of the first clamping groove 120 and the second clamping groove 220, respectively.

[0023] The drive mechanism 300 is connected to the first gripper 100 and the second gripper 200 respectively. The drive mechanism 300 can drive the first gripper 100 and the second gripper 200 to move closer to each other so that the first wire clamping groove 120 and the second wire clamping groove 220 form a wire clamping space 500 for accommodating the wire 400. At least part of the sidewall of the wire clamping space 500 is adapted to the shape of the wire 400. The drive mechanism 300 can also drive the first gripper 100 and the second gripper 200 to move away from each other to provide sufficient space for the wire 400 to be threaded through.

[0024] As can be seen from the above technical solution, the provided wire clamping claw is more targeted and reasonable in structural design compared to the existing wire clamping module composed of eight blades. First, the first wire clamping groove 120 of the first clamping claw 100 and the second wire clamping groove 220 of the second clamping claw 200 cooperate to form a wire clamping space 500 for accommodating the wire 400. At least part of the sidewall of the wire clamping space 500 is adapted to the shape of the wire 400, which can effectively avoid the problem of wire sheathing jamming caused by the small contact area and uneven force of the traditional blade-type wire clamping module. Second, compared with the easily worn blade structure, the combined design of the wire clamping block and the wire clamping groove distributes the force more evenly during the clamping process, which can significantly reduce the wear rate of the wire clamping claw and reduce failures such as failure to clamp the wire or wire slippage caused by the wear of the first wire clamping block 110 and / or the second wire clamping block 210, thereby greatly reducing the number of equipment downtimes and reducing the defective product rate.

[0025] Meanwhile, due to the reduced wear rate, there is no need to frequently replace the components in the wire clamping jaws, which not only reduces spare parts procurement costs but also saves on labor maintenance costs and equipment downtime costs associated with replacing parts. Furthermore, the drive mechanism 300 drives the first clamping jaw 100 and the second clamping jaw 200 to open and close. When open, this provides sufficient space for threading wires 400 of different diameters, improving the equipment's adaptability to different wire types 400. When closed, the clamping space 500 enables positioning, ensuring the wire 400 maintains a stable posture during clamping, thus guaranteeing subsequent wire stripping processing and further improving the overall processing efficiency and quality of the wire stripping machine.

[0026] In some examples, please refer to Figure 3 (For clarity, only a portion of the mounting base 321 is shown.) The first gripper 100 includes a first body 150 extending in the third direction Z. A first clamping block 110 is connected to the first body 150 and is located on the side of the first body 150 facing the second gripper 200, extending towards the second gripper 200. It should be noted that the connection method between the first clamping block 110 and the first body 150 is not specifically limited in this embodiment; any connection between the first body 150 and the first clamping block 110 is acceptable.

[0027] The second gripper 200 includes a second body 250, which is disposed opposite to the first body 150 in the first direction X. A second clamping block 210 is connected to the second body 250, and the second clamping block 210 is disposed on the side of the second body 250 facing the first gripper 100, extending towards the first gripper 100. It should be noted that the connection method between the second clamping block 210 and the second body 250 is not specifically limited in this embodiment; any method that enables the connection between the second body 250 and the second clamping block 210 is acceptable.

[0028] In some embodiments, such as Figure 2As shown, to further optimize the wire clamping positioning effect, the first wire clamping block 110 has a first arc-shaped surface 130 on the side facing the second clamping claw 200. The first arc-shaped surface 130 is recessed in the direction away from the second clamping claw 200 to form a first wire clamping groove 120. When the first wire clamping groove 120 and the second wire clamping groove 220 cooperate to form the wire clamping space 500, the wire 400 can be stably clamped. However, in practical applications, there is still a possibility that the position of the wire 400 may be offset, making it difficult to accurately match the reference position required for the subsequent wire stripping process, thus affecting the wire stripping accuracy. The arc-shaped structure of the first arc-shaped surface 130 has a guiding function. During the clamping process, the wire 400 can be guided towards the center of the wire clamping space 500 through the guiding effect of the first arc-shaped surface 130, so that the final position of the wire 400 is closer to the preset reference position for the subsequent wire stripping process.

[0029] In some embodiments, such as Figure 2 As shown, to further improve the wire stripping accuracy, a second arc-shaped surface 230 is provided on the side of the second clamping block 210 facing the first arc-shaped surface 130. The second arc-shaped surface 230 is recessed in the direction away from the first clamping claw 100 to form a second clamping groove 220. That is, the first arc-shaped surface 130 and the second arc-shaped surface 230 cooperate to guide the wire 400 towards the center of the clamping space 500. This is equivalent to the wire 400 being subjected to a guiding force towards the center of the clamping space 500 on both sides in the first direction X. The positional deviation of the wire 400 is greatly reduced, and it can more stably conform to the reference position required by the subsequent wire stripping process.

[0030] In some examples, the second arc-shaped surface 230 may be provided only on the side of the second clamping block 210 facing the first arc-shaped surface 130. The arc-shaped structure of the second arc-shaped surface 230 has a guiding function. During the clamping process, the wire 400 can be guided towards the center of the clamping space 500 through the guiding effect of the second arc-shaped surface 230, so that the final position of the wire 400 is closer to the preset reference position for subsequent wire stripping processing.

[0031] In some embodiments, please refer to Figure 4To further optimize the guiding effect and clamping stability of the first arc surface 130 and the second arc surface 230 on the wire 400, in the second direction Y, the size of the first arc surface 130 is L1, and the size of the first clamping block 110 is L2, satisfying 0.5≤L1 / L2<1; the size of the second arc surface 230 is L3, and the size of the second clamping block 210 is L4, satisfying 0.5≤L3 / L4<1. In other words, L1 / L2 can be any value from 0.5, 0.6, 0.7, 0.8, 0.9, 0.91, 0.92, 0.93, 0.94, 0.95, 0.96, 0.97, 0.98, 0.99, or a range between any two values; L3 / L4 can be any value from 0.5, 0.6, 0.7, 0.8, 0.9, 0.91, 0.92, 0.93, 0.94, 0.95, 0.96, 0.97, 0.98, 0.99, or a range between any two values. This dimensional ratio was not chosen arbitrarily, but rather determined after multiple tests based on actual wire clamping requirements and structural stability. Taking the first arc-shaped surface 130 as an example, if the ratio of L1 / L2 is too small (less than 0.5), the area occupied by the first arc-shaped surface 130 on the first wire clamping block 110 is relatively narrow. In this case, the guiding effect of the first arc-shaped surface 130 on the wire 400 is weak. At the same time, the narrower first arc-shaped surface 130 will also reduce the contact area with the wire 400. When the ratio of L1 / L2 approaches 1, the first arc-shaped surface 130 occupies one side of the first wire clamping block 110 in the second direction Y, so the contact area between the first wire clamping block 110 and the second wire clamping block 210 is too small, which is not conducive to the docking of the first wire clamping block 110 and the second wire clamping block 210. The second arc-shaped surface 230 similarly has the same function as the first arc-shaped surface 130.

[0032] It should be noted that the dimensions of the first arc-shaped surface 130 are the same as those of the second arc-shaped surface 230. That is, L1=L3 and L2=L4. In other words, the first wire clamping block 110 and the second wire clamping block 210 form a symmetrical structure, and they can be produced using the same set of processing molds and processes. There is no need to design molds for the two types of wire clamping blocks separately, which reduces mold development costs and lowers the complexity of the production process.

[0033] In some embodiments, such as Figure 2As shown, the first gripper 100 has a first guide groove 140 on the side away from the drive mechanism 300, and the first guide groove 140 communicates with the first wire clamping groove 120. The second gripper 200 has a second guide groove 240 on the side away from the drive mechanism 300, and the second guide groove 240 communicates with the second wire clamping groove 220. When the drive mechanism 300 drives the first gripper 100 and the second gripper 200 to approach each other, the first guide groove 140 and the second guide groove 240 form a guide space, which can better guide the wire 400 into the wire clamping space 500. Specifically, during the process of the drive mechanism 300 driving the first gripper 100 and the second gripper 200 to approach each other, the first guide groove 140 and the second guide groove 240 will simultaneously engage to form the guide space. Compared to the wire clamping space 500, the entrance end of the guide space (the end away from the drive mechanism 300) can be set to a wider open shape, which can effectively expand the capture range of the wire 400. Even if there is a certain deviation in the initial placement of the wire 400, the position can be gradually corrected by the guidance of the groove wall of the guide space.

[0034] In some embodiments, such as Figure 3 As shown, the drive mechanism 300 includes a drive cylinder 310 and a connecting rod assembly 320. The output shaft of the drive cylinder 310 extends along a third direction Z. The connecting rod assembly 320 is connected to the output shaft of the drive cylinder 310, the first gripper 100, and the second gripper 200. It should be noted that the drive cylinder 310, as a power source, has its output shaft extending along a third direction Z. This orientation forms a reasonable spatial layout with the first direction X of the clamping jaws' opening and closing, avoiding spatial interference between components and allowing for the conversion of the power direction via the connecting rod assembly 320. The connecting rod assembly 320 transmits power evenly and synchronously to the first gripper 100 and the second gripper 200. Specifically, the connecting rod assembly 320 is rotatably connected to the first body 150 and the second body 250.

[0035] In some embodiments, such as Figure 3 As shown, the linkage assembly 320, as a component in the drive mechanism 300 that realizes power transmission and motion conversion, includes a mounting base 321, a connecting block 322, a first transmission block 323, a second transmission block 324, a first connecting shaft 325, and a second connecting shaft 326.

[0036] The mounting base 321, serving as the support structure for the connecting rod assembly 320, is located on the side of the drive cylinder 310 facing the first gripper 100. It has an internal accommodating space within which the output shaft of the drive mechanism 300 is situated. The mounting base 321 also provides a mounting platform for other transmission components. The connecting block 322 is rigidly connected to the output shaft of the drive cylinder 310. The connecting block 322 can move synchronously with the output shaft of the drive cylinder 310 along the third direction Z, directly transmitting the driving force of the drive cylinder 310 to subsequent transmission components.

[0037] The first transmission block 323 and the second transmission block 324 are arranged symmetrically. One end of the first transmission block 323 is rotatably connected to one side of the connecting block 322 via a movable connector, and the other end is also movably connected to the first gripper 100. One end of the second transmission block 324 is movably connected to the other side of the connecting block 322 away from the first transmission block 323, and the other end is movably connected to the second gripper 200. This symmetrical design ensures that the driving force can be evenly distributed to the first gripper 100 and the second gripper 200.

[0038] To enable the gripper to rotate and open, the first connecting shaft 325 and the second connecting shaft 326 are arranged along the second direction Y. The first connecting shaft 325 passes through the first gripper 100 and is fixedly connected to the mounting base 321, so that the first gripper 100 can rotate flexibly toward or away from the second gripper 200 with the first connecting shaft 325 as a fixed axis of rotation. Similarly, the second connecting shaft 326 passes through the second gripper 200 and is fixed to the mounting base 321, providing the second gripper 200 with a symmetrical axis of rotation, so that it can synchronously achieve the rotational action of moving toward or away from the first gripper 100.

[0039] When the drive cylinder 310 is activated, the output shaft of the drive cylinder 310 extends and retracts along the third direction Z, causing the connecting block 322 to move synchronously. The displacement of the connecting block 322 is converted into a pushing or pulling force on the two grippers (the first gripper 100 and the second gripper 200) through the first transmission block 323 and the second transmission block 324. Since the first gripper 100 and the second gripper 200 are respectively rotated around the first connecting shaft 325 and the second connecting shaft 326, under the action of the corresponding transmission blocks, they will rotate symmetrically around their respective axes. When the connecting block 322 moves closer to the two grippers (first gripper 100 and second gripper 200), the first transmission block 323 and the second transmission block 324 respectively push the first gripper 100 and the second gripper 200 to rotate in opposite directions around the axis, thus closing the grippers. When the connecting block 322 moves away from the two grippers (first gripper 100 and second gripper 200), the first transmission block 323 and the second transmission block 324 respectively pull the first gripper 100 and the second gripper 200 to rotate in opposite directions around the axis, thus opening the grippers. In other words, this can convert the linear motion of the drive cylinder 310 into the rotational opening and closing motion of the two grippers (first gripper 100 and second gripper 200).

[0040] Specifically, the first connecting shaft 325 passes through the first body 150 and is fixedly connected to the mounting base 321, so that the first wire clamping block 110 connected to the first body 150 can rotate about the first connecting shaft 325 as the axis of rotation, and can rotate towards or away from the second wire clamping block 210; similarly, the second connecting shaft 326 passes through the second body 250 and is fixed to the mounting base 321, so that the second wire clamping block 210 connected to the second body 250 can rotate about the second connecting shaft 326 as the axis of rotation, so that the second wire clamping block 210 can synchronously move towards or away from the first wire clamping block 110.

[0041] In some embodiments, please refer to Figure 6 To enhance transmission stability and force balance, the first transmission block 323 is arranged in a symmetrical double-block configuration, with the two first transmission blocks 323 respectively positioned on both sides of the connecting block 322 in the second direction Y. Correspondingly, the second transmission block 324 is also configured in two blocks, located at the end of the connecting block 322 in the first direction X away from the first transmission block 323, and symmetrically distributed on both sides of the connecting block 322 in the second direction Y. This symmetrical double-block layout can disperse the concentrated stress during single-block transmission, prevent deformation of the transmission components due to uneven force, and ensure that the power of the connecting block 322 can be evenly transmitted to the corresponding grippers through the two transmission blocks (first transmission block 323 and second transmission block 324), further improving the synchronicity and smoothness of the opening and closing action of the clamping jaws.

[0042] In some embodiments, the linkage assembly 320 further includes a bearing 327. The bearing 327 is disposed between the first connecting shaft 325 and the first gripper 100, and between the second connecting shaft 326 and the second gripper 200. The bearing 327 effectively reduces the frictional resistance when the first body 150 rotates around the first connecting shaft 325 and the second body 250 rotates around the second connecting shaft 326, making the rotation of the first gripper 100 and the second gripper 200 more flexible and smooth, reducing component wear caused by excessive friction, and extending service life.

[0043] According to a second aspect of this disclosure, a wire stripping device is provided, comprising the wire clamping claw, the wire pressing module, and the wire stripping module as described in any of the above embodiments. The wire pressing module is used to clamp the wire 400, and the wire stripping module is used to strip the insulation from the wire 400. This wire stripping device has all the beneficial effects of the aforementioned wire clamping claw, which will not be elaborated further herein.

[0044] It should be noted that the clamping claws first position and clamp the wire 400, solving the problems of slippage and inaccurate positioning in traditional structures; the wire pressing module assists in pressing the wire 400 during stripping to prevent displacement or rotation and enhance the fixing effect; the wire stripping module is equipped with adjustable blades, which can strip the outer sheath of the wire 400 as needed without damaging the internal conductor. The specific structure of the wire stripping device has been disclosed in the prior art, and will not be described in detail here.

[0045] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
