[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0028] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] like Figures 1 to 7 As shown, the wire stripping device of the embodiment of the present invention includes a first pliers body 1, a second pliers body 2, a support member and a wire stripping knife 3, one end of the first pliers body 1 and the second pliers body 2 being hinged is a hinged end 4, the support member includes a wire stripping seat 5 and a limit block 6, the wire stripping seat 5 is arranged on the side of the first pliers body 1 facing the second pliers body 2, and the wire stripping seat 5 is provided with a receiving groove 51 on the side of the second pliers body 2 facing the first pliers body 1, the wire stripping knife 3 is arranged on the side of the second pliers body 2 facing the first pliers body 1, and the wire stripping knife 3 is located above the notch of the receiving groove 51, the wire stripping knife 3 has an inclined cutting portion, the cutting portion is inclined from an end adjacent to the second pliers body 2 toward an end away from the second pliers body 2 and toward a direction away from the center of the receiving groove 51, the cutting portion can cut the outer skin of the wire exposed outside the receiving groove 51, the limit block 6 is arranged on the wire stripping seat 5, and the second pliers body 2 is provided with a limiting groove 21 at a position relative to the limiting block 6, and the limiting block 6 is inserted into the limiting groove 21.

[0032] It can be understood that compared to cutting the wire directly, which may cause the force to be concentrated at a certain point or in a certain direction of the cutting part, which may easily cause damage to the cutting part or material rupture, the wire stripping device tilts the cutting part of the wire stripping knife 3. The tilt angle helps to disperse the force in multiple directions, which can make the cutting force of the cutting part on the wire sheath more evenly distributed, make the cutting of the sheath more stable and smooth, and reduce the pressure on the material; through the coordinated setting of the limit block 6 and the limit groove 21, the stability and guidance of the relative movement of the first clamp body 1 and the second clamp body 2 can be effectively improved, thereby ensuring the movement guidance and stability of the cutting part, the cutting position has high accuracy, and effectively ensures the flatness of the cutting surface of the wire sheath, and ensures the production quality of wire stripping.

[0033] Furthermore, if Figure 1 and Figure 3 As shown, the support member also includes a mounting seat 7, which is detachably arranged on the side of the first clamp body 1 facing the second clamp body 2, and the length of the first clamp body 1 extends along the first direction (the first direction is the X direction shown in the figure), and the limit block 6 is arranged on the side of the mounting seat 7 away from the hinge end 4 along the first direction, and the mounting seat 7 is penetrated by at least two wire holes 71 along the second direction (the second direction is the Y direction shown in the figure), and the side of the mounting seat 7 away from the first clamp body 1 is provided with a connecting port 72 relative to each wire hole 71, and the connecting port 72 is communicated with the wire hole 71, and a crimping head 8 is provided on the second clamp body 2 relative to each connecting port 72, and the crimping head 8 can pass through the connecting port 72 to crimp the wires in the wire hole 71, and the first direction is arranged perpendicular to the second direction. By setting the mounting seat 7 and the crimping head 8, the stripped wire can be inserted into the wire hole 71, and the first clamp body 1 and the second clamp body 2 are crimped, so that the crimping head 8 can pass through the connecting port 72 to crimp the ends of the two wires in the wire hole 71, thereby enriching the use function of the wire stripping device and improving the practicability of the wire stripping device.

[0034] Of course, the connection port 72 is provided to facilitate the pressing head 8 to pass through the connection port 72 and be inserted into the wire hole 71 . On the other hand, the connection port 72 can effectively guide the pressing head 8 and improve the pressing accuracy of the pressing head 8 .

[0035] In addition, the detachable setting of the mounting seat 7 facilitates the production and disassembly of the wire stripping device, and the mounting seat 7 can be replaced later to maintain the wire stripping device, thereby reducing maintenance costs. For example, a fixing groove is provided on the first clamp body 1, and through holes are provided on both side surfaces of the first clamp body 1 along the second direction, the mounting seat 7 is inserted into the fixing groove, and threaded holes are provided on both side surfaces of the mounting seat 7 along the second direction at positions relative to the through holes, and bolts are passed through the through holes and screwed into the threaded holes to achieve connection between the mounting seat 7 and the first clamp body 1, and the threaded connection is convenient and stable.

[0036] Optionally, the centers of all the wire holes 71 are located on the same straight line extending along the first direction, and the apertures of each wire hole 71 are different. By providing wire holes 71 with different apertures, wires of different wire diameters can be placed in corresponding wire holes 71 for crimping, thereby ensuring the stability and reliability of crimping of wires of different wire diameters.

[0037] Furthermore, if Figure 1 and Figure 2As shown, a mounting groove 22 is provided on one side of the second pliers body 2 along the second direction. The length of the mounting groove 22 extends around the rotation direction of the second pliers body 2. The pressing head 8 is slidably connected in the mounting groove 22 via a first latch. The second clamp body 2 rotates around the intersection point, and the crimping head 8 extends in the vertical direction. Therefore, in order to enable the crimping head 8 to be accurately inserted into the threading hole through the connecting port 72, an arc-shaped installation groove 22 is set. In the natural state, the crimping head 8 hangs at the bottom of the installation groove 22 due to its own gravity. During the movement of the second clamp body 2 relative to the first clamp body 1, the crimping head 8 is inserted in the connecting port 72. With the continuous movement of the second clamp body 2, the connecting port 72 limits the crimping head 8, and the crimping head 8 abuts against the wire to push the end of the crimping head 8 away from the wire in the opposite direction to slide along the installation groove 22 until it slides to the top of the installation groove 22, so that the second clamp body 2 pushes the crimping head 8 to crimp the wire on the mounting seat 7 of the first clamp body 1. The structure is simple, and the crimping stability and crimping accuracy of the crimping head 8 are ensured.

[0038] Preferably, if Figure 1 and Figure 4 As shown, the mounting seat 7 is also provided with a clamping strip 9 on both sides along the second direction, the length of the clamping strip 9 is along the first direction, and the clamping strip 9 and the wire stripping seat 5 are spaced apart along the third direction (the third direction is the vertical direction, i.e. the Z direction shown in the figure), the clamping strip 9 is provided with a clamping groove 91 relative to the accommodating groove 51, the groove bottom of the accommodating groove 51 and the groove bottom of the clamping groove 91 are spaced apart to form a clamping groove for clamping the wire, and the first direction and the second direction are both arranged at an angle to the third direction. By providing the clamping groove 91 on the clamping strip 9, the side of the wire away from the groove bottom of the accommodating groove 51 is limited, so that the wire can be stably limited in the clamping groove formed by the groove bottom of the accommodating groove 51 and the groove bottom of the clamping groove 91, thereby ensuring the placement stability of the wire, thereby ensuring the stability of subsequent wire stripping of the battery cell.

[0039] Furthermore, the limit block 6 can be slidably arranged along the third direction on the side of the wire stripping seat 5 away from the hinged end 4, and the limit block 6 can be selectively fixed to the wire stripping seat 5. By adjusting the height of the limit block 6, the pressing depth of the second pliers 2 is limited, and the cutting of the outer skins of different wires with different thicknesses can be achieved, avoiding the damage to the wire conductor caused by the cutting part of the wire stripping knife 3 being pressed too deep, thereby improving the stripping compatibility of the wire stripping device. For example, a threaded hole is provided on the side of the wire stripping seat 5 away from the hinged end 4, and a strip hole is provided on the limit block 6, and the strip hole extends along the third direction. After adjusting the position of the limit block 6, the bolt is passed through the strip hole and screwed into the threaded hole, so that the head of the bolt is pressed against the limit block 6, thereby realizing the connection between the limit block 6 and the wire stripping seat 5.

[0040] In some embodiments, Figure 1 and Figure 2As shown, the wire stripping device further includes a first cutter 10 and a second cutter 11. The wire stripping seat 5 has a support surface 52 away from the first pliers body 1. The first cutter 10 is detachably arranged on the wire stripping seat 5, and the first cutter 10 at least partially protrudes from the support surface 52. The second pliers body 2 is provided with a second cutter 11 at a position relative to the first cutter 10, and the second cutter 11 can abut against the first cutter 10. The part of the wire to be cut is placed between the first cutter 10 and the second cutter 11, and the first pliers body 1 and the second pliers body 2 are pressed together so that the first cutter 10 and the second cutter 11 are close to each other to cut the wire, thereby ensuring the flatness of the end of the wire and facilitating cutting.

[0041] Optionally, the wire stripping device further includes a third cutter 12. The third cutter 12 is arranged at a position of the second pliers body 2 relative to the support surface 52. The distance between the second cutter 11 and the support surface 52 is greater than the distance between the third cutter 12 and the support surface 52. The third cutter 12 can abut against the support surface 52. For some wires with larger wire diameters or higher wire hardness, the method of cutting with two cutters arranged opposite to each other may cause blade damage. Therefore, the wire is placed on the support surface 52, and the support surface 52 supports the wire and cooperates with the third cutter 12 to cut, thereby improving the cutting performance of the wire stripping device. Of course, the hardness of the third cutter 12 should be higher than that of the second blade to ensure the cutting effect of the third cutter 12.

[0042] In other embodiments, Figure 6 and Figure 7As shown, the wire stripping device also includes a locking assembly, which includes a positioning block 13, a connecting block 14, a clamping block 15 and a tension spring 16. A positioning block 13 is provided on the side of the wire stripping seat 5 away from the hinged end 4. A plurality of clamping grooves 131 are provided on the side of the positioning block 13 away from the hinged end 4. All the clamping grooves 131 are arranged at intervals along the third direction. The connecting block 14 includes a mounting portion 141 and a connecting portion 142 arranged at an angle. The mounting portion 141 is detachably connected to the second clamp body 2. The clamping block 15 is rotatably arranged on the connecting portion 142. One end of the clamping block 15 is connected to the mounting portion 141 through the tension spring 16. The end of the clamping block 15 away from the tension spring 16 is the clamping portion 151. The clamping portion 151 can be clamped in the clamping groove 131. The tension spring 16 always has a movement tendency to drive the clamping portion 151 to clamp in the clamping groove 131. During operation, when the crimping head 8 presses the wires, the tension spring 16 will tighten the clamping block 15, so that the clamping portion 151 on the clamping block 15 is clamped into the clamping groove 131 of the positioning block 13, thereby completing the positioning and fixing of the crimping operation, which not only ensures the stability during the crimping process, but also improves the accuracy and convenience of the operation, and can also save grip force during use, so that the user has a sense of assistance. At the same time, when it is necessary to release the fixation, just pull the clamping block 15 slightly to make the clamping portion 151 disengage from the clamping groove 131 to proceed to the next step, which greatly facilitates the use of the user.

[0043] Furthermore, the locking assembly further includes a locking button 17, through which the clamping block 15 is rotatably connected to the connecting portion 142, and the locking button 17 can be selectively fixed to the connecting portion 142. For example, a first locking hole is provided on the clamping block 15, and a second locking hole is provided on the connecting portion 142. The locking button 17 is inserted into the first locking hole and the second locking hole. A locking portion is provided on the locking button 17, and a locking groove is provided at a position corresponding to the locking portion on the inner wall of the first locking hole and the second locking hole. When the locking portion of the locking button 17 is inserted into the locking groove, the clamping block 15 is fixedly connected to the connecting portion 142, ensuring that the clamping block 15 and the connecting portion 142 are firmly combined.
