[0042] To make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Terms such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end" used in the present application to represent spatial relative positions are used to describe the relationship of a unit or feature relative to another unit or feature as shown in the accompanying drawings for the purpose of convenience of explanation. Terms of spatial relative position may be intended to include different orientations of the device in use or work other than the orientation shown in the figure. For example, if the device in the figure is turned over, the unit described as being "below" or "below" other units or features will be located "above" other units or features. Therefore, the exemplary term "below" can encompass both the above and below orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptive words used in this article are interpreted accordingly.

[0043] In addition, the terms "installed", "set", "provided with", "connected", "slidingly connected", "fixed", and "sleeved" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in this application are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0045] See attached Figure 1 To Attachment Figure 6As shown, an electroplating fixture 10 provided in an embodiment of the present application includes a first clamp arm 101 and a second clamp arm 102, and the first clamp arm 101 and the second clamp arm 102 are movably connected via a linkage assembly, and the linkage assembly is installed on an adjusting rod 103; at least part of the first clamp arm 101 and the second clamp arm 102 are conductive and form a conductive area 122; in a working state, the adjusting rod 103 drives the linkage assembly to move axially, so that the first clamp arm 101 and the second clamp arm 102 are close to or away from each other, and when the first clamp arm 101 and the second clamp arm 102 are close to each other, the conductive area 122 is in electrical contact with the contacted part 20. In this way, the first clamp arm 101 and the second clamp arm 102 are repeatedly moved closer or farther away to realize the opening and closing of the first clamp arm 101 and the second clamp arm 102. When the first clamp arm 101 and the second clamp arm 102 are farther away from each other and in an open state, the contact member 20 can enter between the first clamp arm 101 and the second clamp arm 102. When the first clamp arm 101 and the second clamp arm 102 are closer to each other and in a closed state, the contact member 20 is clamped by the first clamp arm 101 and the second clamp arm 102. In addition, the contact member 20 can be a battery cell or a conductive material. When the contact member 20 is a battery cell, the battery cell can directly obtain the negative current transmitted by the first clamp arm 101 and the second clamp arm 102 through the conductive area 122. When the contact member 20 is a conductive material, the conductive material transmits the obtained negative current to the battery cell, so that the battery cell can become a cathode during the electroplating process.

[0046] In one possible implementation, see the attached Figure 1 To Attachment Figure 3 As shown, both ends of the first clamp arm 101 and the second clamp arm 102 are a clamping end and a control end respectively, and the control end is coupled to the adjustment rod 103; the first clamp arm 101 and the second clamp arm 102 both have a lever fulcrum to support the first clamp arm 101 and the second clamp arm 102; in the working state, the adjustment rod 103 moves along its own axial direction, driving the first clamp arm 101 and the second clamp arm 102 to rotate around its own lever fulcrum, so that the two clamping ends are closed or opened.

[0047] In this embodiment, one specific structure is shown in the attached Figure 1 As shown, the linkage assembly includes two connecting rods and a hinge shaft 106. The first rotating rod 104 is rotatably provided on the control ends of the first clamp arm 101 and the second clamp arm 102. The two first rotating rods 104 are respectively connected to one end of the two connecting rods, and the other end of the connecting rod is hinged to the hinge shaft 106. In the working state, the adjusting rod 103 drives the connecting rod to rotate, so that the first clamp arm 101 and the second clamp arm 102 are closer to or farther from each other. Specifically, when the adjusting rod 103 moves along its own axial direction, the two hinge shafts 106 rotate under the drive of the adjusting rod 103, and respectively drive the first clamp arm 101 and the second clamp arm 102 to move.

[0048] Furthermore, the electroplating fixture 10 further includes a support seat 107, and the adjustment rod 103 penetrates the support seat 107; the first clamp arm 101 and the second clamp arm 102 are both rotatably provided with a second rotating rod 105 on the lever fulcrum, and the second rotating rod 105 is connected to one end of a fixed rod 108, and the other end of the fixed rod 108 is fixedly connected to the support seat 107. The adjustment rod 103 can move along a first direction 30 and a second direction 40, and the first direction 30 and the second direction 40 are two opposite directions extending along the axial direction of the adjustment rod 103. When the adjustment rod 103 moves toward the second direction 40, the first clamp arm 101 and the second clamp arm 102 are converted from an open state to a closed state. Specifically, when the adjusting rod 103 moves in the second direction 40, the end of the hinge shaft 106 connected to the adjusting rod 103 moves in the second direction 40, and the hinge shaft 106 rotates clockwise. At this time, the hinge shaft 106 provides a thrust to the first rotating rod 104. Since the fixed rod 108 is connected to the lever fulcrum, the two hinge shafts 106 respectively drive the first clamp arm 101 and the second clamp arm 102 to approach each other, thereby clamping the contact member 20 to be contacted; when the adjusting rod 103 moves in the first direction 30, the end of the hinge shaft 106 connected to the adjusting rod 103 moves in the first direction 30, and the hinge shaft 106 rotates counterclockwise. At this time, the hinge shaft 106 provides a pulling force to the first rotating rod 104. Since the fixed rod 108 is connected to the lever fulcrum, the two hinge shafts 106 respectively drive the first clamp arm 101 and the second clamp arm 102 to move away from each other.

[0049] Furthermore, the electroplating fixture further includes a power piece 125, which has two pieces, one end of which is connected to the first rotating rod 104 of the control end of the first clamp arm 101 and the second clamp arm 102, and the other end is connected to the adjustment rod 103. When the adjustment rod 103 moves in the second direction 40, the power piece 125 provides a driving force to the control end, so that the first clamp arm 101 and the second clamp arm 102 can be further closed under the driving force of the power piece 125. Specifically, the power piece 125 can be a workpiece such as a spring, a driving rod, etc. that can provide a driving force for the first clamp arm 101 and the second clamp arm 102 when the adjustment rod 103 moves in the second direction 40. The power piece 125 can also be other workpieces, and the present application does not limit this.

[0050] Another structure in this embodiment is shown in the attached Figure 2 and attached Figure 3As shown, the electroplating fixture 10 also includes a support seat 107, and the adjustment rod 103 passes through the support seat 107; the linkage assembly includes three hinge shafts 106, the first hinge shaft 1061 is arranged at the control end of the first clamp arm 101 and the second clamp arm 102, and passes through the first clamp arm 101, the second clamp arm 102 and the adjustment rod 103, and a first through hole 1011 and a second through hole 1021 are formed on the first clamp arm 101 and the second clamp arm 102 respectively, the second hinge shaft 1062 is arranged at the lever fulcrum of the first clamp arm 101, and passes through the first clamp arm 101 and the support seat 107, and a third through hole 1012 is formed on the first clamp arm 101, and the third hinge shaft 1063 is arranged at the lever fulcrum of the second clamp arm 102, passes through the second clamp arm 102 and the support seat 10 7, and a fourth through hole 1022 is formed on the second clamping arm 102; wherein, the first through hole 1011 and the second through hole 1021 are waist holes to provide a certain movement space for the first clamping arm 101 and the second clamping arm 102, or the third through hole 1012 and the fourth through hole 1022 are waist holes to provide a certain movement space for the first clamping arm 101 and the second clamping arm 102; in the working state, the first through hole 1011 and the second through hole 1021 at least partially overlap, the third through hole 1012 and the first through hole 1011 are respectively arranged on both sides of the first clamping arm 101, the fourth through hole 1022 and the second through hole 1021 are respectively arranged on both sides of the second clamping arm 102, and the adjusting rod 103 drives the hinge shaft 106 to move, so that the first clamping arm 101 and the second clamping arm 102 are closer to or farther away from each other. Specifically, the adjusting rod 103 can move along the first direction 30 and the second direction 40, and the first direction 30 and the second direction 40 are two opposite directions extending axially along the adjusting rod 103. During the movement of the adjusting rod 103, the first through hole 1011 and the second through hole 1021 rotate around the first hinge axis 1061 and can slide with the first hinge axis 1061, or the first through hole 1011 and the second through hole 1021 rotate around the first hinge axis 1061, the third through hole 1012 rotates around the second hinge axis 1062 and can slide with each other, and the fourth through hole 1022 rotates around the third hinge axis 1063 and can slide with each other, so that the electroplating fixture 10 is in an open state or a closed state.

[0051] See attached Figure 3 As shown in Figure a, the first through hole 1011 and the second through hole 1021 are formed as waist holes with their long axes in the left-right direction, the third through hole 1012 can only rotate around the second hinge axis 1062, and the fourth through hole 1022 can only rotate around the third hinge axis 1063. The first through hole 1011 and the second through hole 1021 can respectively move relative to the first hinge axis 1061, and the adjustment rod 103 drives the first clamping arm 101 and the second clamping arm 102 to rotate around the hinge axis 106, and the first hinge axis 1061 moves toward the edge of the first through hole 1011 and the second through hole 1021, so that the electroplating fixture 10 forms an attachment Figure 3The state shown in Figure d in the figure prevents the first clamping arm 101 and the second clamping arm 102 from being unable to switch between the loose state and the clamping state relative to each other.

[0052] See attached Figure 3 As shown in Figure b, the diameters of the first through hole 1011 and the second through hole 1021 are both larger than the diameter of the first hinge shaft 1061, the third through hole 1012 can only rotate around the second hinge shaft 1062, and the fourth through hole 1022 can only rotate around the third hinge shaft 1063. The first through hole 1011 and the second through hole 1021 can respectively move relative to the first hinge shaft 1061, and the adjustment rod 103 drives the first clamping arm 101 and the second clamping arm 102 to rotate around the hinge shaft 106, and the first hinge shaft 1061 moves toward the edge of the first through hole 1011 and the second through hole 1021, so that the electroplating fixture 10 forms an attachment. Figure 3 The state shown in Figure e in the figure avoids the first clamping arm 101 and the second clamping arm 102 from being unable to switch between the loose state and the clamping state relative to each other.

[0053] See attached Figure 3 As shown in Figure c, the first through hole 1011 and the second through hole 1021 can only rotate around the first hinge axis 1061, the third through hole 1012 is formed as a waist hole with the long axis direction in the left and right direction, the third through hole 1012 can move left and right with the second hinge axis 1062, the fourth through hole 1022 can move relative to the third hinge axis 1063, the adjustment rod 103 drives the first clamping arm 101 and the second clamping arm 102 to rotate around the hinge axis 106, the second hinge axis 1062 moves toward the edge of the third through hole 1012, and the third hinge axis 1063 moves toward the edge of the fourth through hole 1022, so that the electroplating fixture 10 forms an attachment Figure 3 The state shown in Figure f prevents the first clamping arm 101 and the second clamping arm 102 from being unable to switch between the loose state and the clamping state relative to each other.

[0054] It should be noted that, while ensuring that the first through hole 1011 and the second through hole 1021, or the third through hole 1012 and the fourth through hole 1022 have a certain movement space for the first clamp arm 101 and the second clamp arm 102 to move relative to each other, the through holes can also adopt other shapes, and the present application does not limit this.

[0055] Different from the above method, in another achievable implementation, see the attached Figure 4As shown, the electroplating fixture 10 also includes a support seat 107, on which two slide grooves are provided, and the two slide grooves are horizontally arranged at both ends of the support seat 107, and the first clamp arm 101 and the second clamp arm 102 are slidably connected to the two slide grooves respectively; the linkage assembly includes a first extension rod 109, a second extension rod 110 and a hinge shaft 106, the first clamp arm 101 and the second clamp arm 102 are hinged to one end of the first extension rod 109 and the second extension rod 110 respectively, and the other ends of the first extension rod 109 and the second extension rod 110 are hinged to the adjustment rod 103 through the hinge shaft 106, and the first extension rod 109 and the second extension rod 110 both pass through the support seat 107; in the working state, the adjustment rod 103 drives the hinge shaft 106 to move, so that the first clamp arm 101 and the second clamp arm 102 are close to or away from each other along the length of the slide groove. The first extension rod 109 and the second extension rod 110 both penetrate the support seat 107, and can drive the first clamp arm 101 and the second clamp arm 102 to move under the drive of the adjustment rod 103. The support seat 107 is also provided with an adjustment port, which is arranged on the support seat with a spacing between the adjustment port and the slide slot, and the first extension rod 109 and the second extension rod 110 both pass through the adjustment port. When the adjustment rod 103 moves along the axial direction, the first extension rod 109 and the second extension rod 110 both move in the adjustment port. In addition, the adjustment rod 103 can move along the first direction 30 and the second direction 40, which are respectively arranged at two different ends of the axial direction of the adjustment rod 103. When the adjustment rod 103 moves from the first direction 30 to the second direction 40, the first clamp arm 101 and the second clamp arm 102 are converted from an open state to a closed state. For the convenience of description, the first extension rod 109 and the second extension rod 110 are collectively referred to as extension rods below.

[0056] Specifically, when the adjusting rod 103 moves in the first direction 30, the end of the extension rod connected to the adjusting rod 103 moves in the first direction 30, and the two extension rods provide thrust to the first clamp arm 101 and the second clamp arm 102 respectively, so that the first clamp arm 101 and the second clamp arm 102 respectively slide horizontally along the length of the two slide grooves, and move away from each other under the push of the extension rods, thereby achieving the opening of the electroplating fixture 10; when the adjusting rod 103 moves in the second direction 40, the end of the extension rod connected to the adjusting rod 103 moves in the second direction 40, and the two extension rods provide pulling force to the first clamp arm 101 and the second clamp arm 102 respectively, so that the first clamp arm 101 and the second clamp arm 102 respectively slide along the length of the two slide grooves, and move closer to each other under the pulling of the extension rods, thereby achieving the closing of the electroplating fixture 10.

[0057] Furthermore, the support seat 107 also has limit seats located on both sides of the adjustment rod 103, or limit seats located on both sides of the adjustment rod 103 are also arranged on the support seat 107. By setting the limit seats, the adjustment rod 103 is restricted in the horizontal direction, so that the adjustment rod 103 can only move axially, thereby preventing the adjustment rod 103 from being unable to provide an opening or closing force to the first clamp arm 101 and the second clamp arm 102.

[0058] Different from the above method, in another achievable implementation, see the attached Figure 5 As shown, the electroplating fixture 10 also includes a support seat 107, a slide groove is provided on the support seat 107, the first clamp arm 101 is slidably connected with the slide groove, the second clamp arm 102 is arranged on the support seat 107, and the first clamp arm 101 and the second clamp arm 102 are respectively arranged at both ends of the support seat 107; the linkage assembly includes a first extension rod 109 and a hinge shaft 106, the first clamp arm 101 is hinged to one end of the first extension rod 109, the other end of the first extension rod 109 is hinged to the adjustment rod 103 through the hinge shaft 106, and the first extension rod 109 passes through the support seat 107; in the working state, the adjustment rod 103 drives the hinge shaft 106 to move, so that the first clamp arm 101 is close to or away from the second clamp arm 102 along the length of the slide groove. Among them, the first extension rod 109 passes through the support seat 107, and can drive the first clamp arm 101 to move under the drive of the adjustment rod 103. The support seat 107 is also provided with an adjustment port, which is spaced apart from the slide slot on the support seat, and the first extension rod 109 passes through the adjustment port. When the adjustment rod 103 moves along the axial direction, the first extension rod 109 moves in the adjustment port. In addition, the adjustment rod 103 can move along the first direction 30 and the second direction 40. The first direction 30 and the second direction 40 are respectively arranged at two different ends of the axial direction of the adjustment rod 103. When the adjustment rod 103 moves from the first direction 30 to the second direction 40, the first clamp arm 101 and the second clamp arm 102 are converted from an open state to a closed state.

[0059] Specifically, when the adjusting rod 103 moves in the first direction 30, the first extension rod 109 connected to the adjusting rod 103 at one end moves in the first direction 30, and the first extension rod 109 provides a thrust to the first clamp arm 101, so that the first clamp arm 101 slides horizontally along the length of the slide slot. Since the position of the second clamp arm 102 is fixed, when the first clamp arm 101 moves away from the second clamp arm 102, the electroplating fixture 10 can be opened; when the adjusting rod 103 moves in the second direction 40, the first extension rod 109 connected to the adjusting rod 103 at one end moves in the second direction 40, and the first extension rod 109 provides a pulling force to the first clamp arm 101, so that the first clamp arm 101 slides horizontally along the length of the slide slot. Since the position of the second clamp arm 102 is fixed, when the first clamp arm 101 moves closer to the second clamp arm 102, the electroplating fixture 10 can be closed.

[0060] Furthermore, the support seat 107 also has limit seats located on both sides of the adjustment rod 103, or limit seats located on both sides of the adjustment rod 103 are also arranged on the support seat 107. By setting the limit seats, the adjustment rod 103 is restricted in the horizontal direction, so that the adjustment rod 103 can only move axially, thereby preventing the adjustment rod 103 from being unable to provide an opening or closing force to the first clamp arm 101 and the second clamp arm 102.

[0061] Different from the above method, in another achievable implementation, see the attached Figure 6 As shown, the linkage assembly includes an elastic member 111 and a hinge shaft 106, and the hinge shaft 106 is installed on the adjustment rod 103. The electroplating fixture 10 also includes a support seat 107. The elastic member 111 has two ends, one end of which is respectively connected to the first clamp arm 101 and the second clamp arm 102, and the other end is respectively connected to the two sides of the support seat 107; in the working state, the adjustment rod 103 drives the hinge shaft 106 to move, so that the first clamp arm 101 and the second clamp arm 102 are driven by the elastic member 111 to move closer to or farther from each other. In this embodiment, the adjustment rod 103 can move along the first direction 30 and the second direction 40, and the first direction 30 and the second direction 40 are respectively arranged at two different ends of the axial direction of the adjustment rod 103. When the adjustment rod 103 moves from the first direction 30 to the second direction 40, the first clamp arm 101 and the second clamp arm 102 are converted from the open state to the closed state.

[0062] Specifically, when the adjusting rod 103 moves in the second direction 40, the ends of the first clamp arm 101 and the second clamp arm 102 connected to the adjusting rod 103 move in the second direction 40, and the ends of the first clamp arm 101 and the second clamp arm 102 away from the adjusting rod 103 rotate in the first direction 30, that is, when one end of the hinge shaft 106 rotates clockwise, the other end must also rotate clockwise. At this time, the first clamp arm 101 and the second clamp arm 102 are close to each other, the elastic member 111 is in a stretched state, and provides the first clamp arm 101 and the second clamp arm 102 with a spring force. The outward elastic force puts the electroplating fixture 10 in a closed state; when the adjusting rod 103 moves in the first direction 30, the first clamp arm 101 and the second clamp arm 102 move in the first direction 30 at one end connected to the adjusting rod 103, and the first clamp arm 101 and the second clamp arm 102 rotate in the second direction 40 at one end away from the adjusting rod 103, that is, when one end of the hinge shaft 106 rotates counterclockwise, the other end must also rotate counterclockwise. At this time, the first clamp arm 101 and the second clamp arm 102 move away from each other, so that the electroplating fixture 10 is in an open state.

[0063] In an achievable implementation, the electroplating fixture 10 further includes an elastic member 114 so that the first clamping arm 101 and the second clamping arm 102 are in a clamping state. The structure of the electroplating fixture 10 can be any one of the following:

[0064] (1) See Appendix Figure 2 As shown, the electroplating fixture 10 further includes a locking member 112, which is disposed on the adjusting rod 103, and an elastic member 114 is sleeved on the adjusting rod 103, with one end thereof abutting against the locking member 112 and the other end abutting against the supporting seat 107;

[0065] (2) See Appendix Figure 6 As shown, the adjustment rod 103 has a step structure 113 , and the elastic member 114 is sleeved on the adjustment rod 103 , with one end thereof abutting against the step structure 113 , and the other end abutting against the support seat 107 .

[0066] That is to say, when the adjusting rod 103 moves in the second direction 40, the elastic member 114 is in a stretched state, and when one end abuts against the support seat 107, there is no longer any stretching space, and the other end will provide an outward elastic force to the locking member 112 or the step structure 113, so that the adjusting rod 103 moves further in the second direction 40, thereby shortening the distance between the first clamping arm 101 and the second clamping arm 102 to increase the clamping force of the electroplating fixture 10.

[0067] Optionally, the elastic member 114 is a workpiece with elastic force such as a spring, a rubber member, a silicone member, etc., and the locking member 112 is an object such as a nut, a clamp, a clip, etc. that can be fixed on the adjustment rod 103. In this embodiment, the elastic member 114 is a spring and the locking member 112 is a nut. The adjustment rod 103 is formed with threads, the locking member 112 is a nut that is screwed with the adjustment rod 103, and the elastic member 114 is a spring, one end of the spring abuts against the support seat 107, and the other end abuts against the nut. When the adjustment rod 103 moves from the first direction 30 to the second direction 40, the compression state of the spring is changed to the tension state, and the elastic thrust of the spring that expands outward pushes the nut to move with the adjustment rod 103 in the second direction 40, thereby further making the first clamping arm 101 and the second clamping arm 102 in a clamped state. The adjusting rod 103 is a stepped shaft (a thin shaft at the top and a thick shaft at the bottom), a spring is sleeved on the thin shaft of the stepped shaft, and one end of the spring abuts against the shaft shoulder (the junction of the thin shaft and the thick shaft), and the other end abuts against the support seat 107. When the adjusting rod 103 moves from the first direction 30 toward the second direction 40, the compression state of the spring is changed to the tension state, and its outward expansion elastic thrust pushes the adjusting rod 103 to move in the second direction 40, thereby further making the first clamping arm 101 and the second clamping arm 102 in a clamped state.

[0068] Furthermore, the locking member 112 is movable on the adjusting rod 103 to be fixed to the adjusting rod 103 at different positions of the adjusting rod 103. By adjusting the position of the locking member 112 on the adjusting rod 103, the clamping force between the first clamping arm 101 and the second clamping arm 102 can be adjusted so that the clamping force is adapted to the force that the object to be contacted can withstand.

[0069] For examples, see the attached Figure 2 As shown, the electroplating fixture 10 includes a support seat 107, an adjustment rod 103, a first clamp arm 101 and a second clamp arm 102, the adjustment rod 103 passes through the support seat 107, and there are three hinge shafts 106. The first hinge shaft 1061 passes through the first clamp arm 101, the second clamp arm 102 and the adjustment rod 103, and a first through hole 1011 and a second through hole 1021 are formed on the first clamp arm 101 and the second clamp arm 102, respectively, forming a first hinge point, and the second hinge shaft 1062 passes through the first clamp arm 101 and the support seat 107. 07, and a third through hole 1012 is formed on the first clamp arm 101 to constitute a second hinge point, the third hinge axis 1063 passes through the second clamp arm 102 and the support seat 107, and a fourth through hole 1022 is formed on the second clamp arm 102 to constitute a third hinge point; wherein, the first through hole 1011 and the second through hole 1021 are waist holes, and the second hinge point and the third hinge point are respectively located on both sides of the first hinge point; and, a spring and a nut are provided on the adjusting rod 103, and both ends of the spring are respectively abutted against the nut and the support seat 107. In the working state, the adjusting rod 103 can move along the first direction 30 and the second direction 40. The first direction 30 and the second direction 40 are respectively arranged at two different ends of the adjusting rod 103 in the axial direction. When the adjusting rod 103 moves in the second direction 40, the spring is in a stretched state, and one end of the spring abuts against the support seat 107, and the other end releases elastic force to the nut to further move the adjusting rod 103 in the second direction 40. At this time, the first hinge shaft 1061 moves in the second direction 40 driven by the adjusting rod 103. Since the waist hole provides a certain moving space, the first clamping arm 101 is connected to the second hinge shaft 1061 in the third through hole 1012. 2, the first through hole 1011 and other parts of the first clamping arm 101 are driven by the first hinge shaft 1061 to move clockwise in the second direction 40. Correspondingly, when the fourth through hole 1022 of the second clamping arm 102 is fixed by the third hinge shaft 1063, the second through hole 1021 and other parts of the second clamping arm 102 are driven by the first hinge shaft 1061 to move counterclockwise in the second direction 40. In this way, when the first clamping arm 101 and the second clamping arm 102 rotate in opposite directions respectively, the first clamping arm 101 and the second clamping arm 102 can be brought close to each other, so that the electroplating fixture 10 is in a closed state.

[0070] In an achievable implementation, the electroplating fixture 10 further includes a clamp arm support assembly to support the first clamp arm 101 and the second clamp arm 102. The structure of the electroplating fixture 10 can be any one of the following:

[0071] (1) See Appendix Figure 7As shown, the clamp arm support assembly includes a set support rod, and the first set 115 and the second set 116 are respectively provided at both ends of the set support rod. The first set 115 is sleeved on the first clamp arm 101 with a first predetermined gap between the two, and the second set 116 is sleeved on the second clamp arm 102 with a second predetermined gap between the two; specifically, the first clamp arm 101 and the second clamp arm 102 are both provided with a limiter 126, and the first clamp arm 101 has two limiters 126, which are respectively provided at the upper and lower ends of the first set 115 to limit the position of the first set 115, and the second clamp arm 102 has two limiters 126, which are respectively provided at the upper and lower ends of the second set 116 to limit the position of the second set 116. Among them, the first set 115 and the second set 116 can be an annular body or a rectangular parallelepiped with a middle portion passing through, and the present application does not limit this.

[0072] When the first clamp arm 101 and the second clamp arm 102 switch from a closed state to an open state, the first clamp arm 101 moves within a first predetermined gap range, and the second clamp arm 102 moves within a second predetermined gap range, that is, the opening distance of the first clamp arm 101 and the second clamp arm 102 is within the predetermined range; when the first clamp arm 101 and the second clamp arm 102 switch from an open state to a closed state, the first clamp arm 101 moves within the first predetermined gap range, and the second clamp arm 102 moves within the second predetermined gap range, that is, the closing distance of the first clamp arm 101 and the second clamp arm 102 is within the predetermined range.

[0073] (2) See Appendix Figure 8 As shown, the clamp arm support assembly includes a first support rod and a second support rod, one end of the first support rod is fixedly arranged, and the other end is provided with a third kit 117, the third kit 117 is sleeved on the first clamp arm 101 and a third predetermined gap is provided therebetween, one end of the second support rod is fixedly arranged, and the other end is provided with a fourth kit 118, the fourth kit 118 is sleeved on the second clamp arm 102 and a fourth predetermined gap is provided therebetween, and the third kit 117 and the fourth kit 118 are connected by a kit support rod; specifically, one end of the first support rod and the second support rod are both fixedly arranged and connected to the support seat 107, and the first support rod and the second support rod support the third kit 117 and the fourth kit 118, so that the first clamp arm 101 and the second clamp arm 102 can move within the first predetermined gap range and the second predetermined gap range, respectively.

[0074] In other words, the opening and closing degree of the electroplating fixture 10 will be limited. In practical applications, in order to achieve the clamping of the electroplating fixture 10 on the contact member 20 , it is necessary to ensure that the distance between the first clamping arm 101 and the second clamping arm 102 is greater than the thickness of the contact member 20 .

[0075] In one possible implementation, see the attached Fig. 9, Attachment Fig.10 As shown, the first clamping arm 101 has a first clamping end 119, and the second clamping arm 102 has a second clamping end 120. The first clamping end 119 and the second clamping end 120 are both located at an end away from the hinge axis 106. At least one clamping area 121 is provided on the first clamping end 119 and the second clamping end 120, and any one of the clamping areas 121 is a conductive area 122.

[0076] When the electroplating jig 10 is in an open state, the first clamping end 119 and the second clamping end 120 are spaced apart from each other, and the spacing distance is greater than or equal to the thickness of the contacted member 20, so that the contacted member 20 can penetrate between the first clamping end 119 and the second clamping end 120; when the electroplating jig 10 is in a closed state, the first clamping end 119 and the second clamping end 120 abut against each other, so that the contacted member 20 can be clamped between the first clamping end 119 and the second clamping end 120. Optionally, the first clamping end 119 is a detachable structure and is detachably disposed on the first clamping arm 101, and the second clamping end 120 is a detachable structure and is detachably disposed on the second clamping arm 102, so that after the electroplating jig 10 is used for a period of time, the first clamping end 119 and the second clamping end 120 can be conveniently replaced.

[0077] The clamping area 121 of at least one of the first clamping end 119 and the second clamping end 120 is made of conductive material. When the electroplating fixture 10 is in a closed state, the first clamping end 119 and the second clamping end 120 abut against each other, the contacted part 20 can be clamped and conductively connected thereto.

[0078] Preferably, a plurality of clamping areas 121 are arranged at intervals on the first clamping end 119 along its length extension direction, and correspondingly, a plurality of clamping areas 121 are arranged at intervals on the second clamping end 120 along its length extension direction. The number of clamping areas 121 on the first clamping end 119 and the second clamping end 120 are equal and their positions correspond to each other one by one, so that when the electroplating fixture 10 is in a closed state, the plurality of clamping areas 121 on the first clamping end 119 and the plurality of clamping areas 121 on the second clamping end 120 abut against each other one by one, so that a plurality of parts to be contacted 20 can be clamped at the same time.

[0079] Among them, the two clamping areas 121 that are located correspondingly and respectively on the first clamping end 119 and the second clamping end 120 can together constitute a conductive clamping area 121. When the conductive clamping area 121 clamps the contact piece 20, it is only necessary to ensure that at least one clamping area 121 that is in contact with the contact piece 20 is in a conductive state, that is, a conductive connection with the contact piece 20 can be achieved.

[0080] Furthermore, the multiple conductive clamping areas 121 located on the electroplating fixture 10 are insulated from each other and may have different conductive states. For example, assuming that the electroplating fixture 10 has two conductive clamping areas 121, namely, a first conductive clamping area 121 and a second conductive clamping area 121, the first conductive clamping area 121 has a first group of first clamping areas 121 and a first group of second clamping areas 121, and the second conductive clamping area 121 has a second group of first clamping areas 121 and a second group of second clamping areas 121, then the conductive structures of the first conductive clamping area 121 and the second conductive clamping area 121 adopt any of the following structures:

[0081] (1) The first group of first clamping regions 121 and the second group of first clamping regions 121 are both in a conductive state, and the first group of second clamping regions 121 and the second group of second clamping regions 121 are both in an insulating state;

[0082] (2) The first group of first clamping regions 121 and the second group of second clamping regions 121 are both in a conductive state, and the first group of second clamping regions 121 and the second group of first clamping regions 121 are both in an insulating state;

[0083] (3) The first group of second clamping regions 121 and the second group of second clamping regions 121 are both in a conductive state, and the first group of first clamping regions 121 and the second group of first clamping regions 121 are both in an insulating state;

[0084] (4) The first group of second clamping regions 121 and the second group of first clamping regions 121 are both in a conductive state, and the first group of first clamping regions 121 and the second group of second clamping regions 121 are both in an insulating state;

[0085] (5) The first group of first clamping regions 121, the first group of second clamping regions 121, the second group of first clamping regions 121, and the second group of second clamping regions 121 are all in a conductive state;

[0086] (6) The first group of first clamping regions 121, the first group of second clamping regions 121, and the second group of first clamping regions 121 are in a conductive state, and the second group of second clamping regions 121 are in an insulating state;

[0087] (7) The first group of first clamping regions 121, the first group of second clamping regions 121, and the second group of second clamping regions 121 are in a conductive state, and the second group of first clamping regions 121 are in an insulating state;

[0088] (8) The second group of first clamping regions 121, the second group of second clamping regions 121, and the first group of first clamping regions 121 are in a conductive state, and the first group of second clamping regions 121 are in an insulating state;

[0089] (9) The second group of first clamping regions 121 , the second group of second clamping regions 121 , and the first group of second clamping regions 121 are in a conductive state, and the first group of first clamping regions 121 are in an insulating state.

[0090] In this way, it can be ensured that at least one clamping area 121 can be in electrical contact with the contact-to-be-contacted part 20 .

[0091] In an achievable implementation, a clamping member 123 is disposed on both the first clamping end 119 and the second clamping end 120. The clamping member 123 may be disposed in the clamping area 121 or between two adjacent clamping areas 121. The structure of the clamping member 123 may be any one of the following:

[0092] (1) The clamping member 123 is a serrated structure, and the serrated structure at the first clamping end 119 matches the serrated structure at the second clamping end 120; when clamping the object to be contacted, the serrated structure of the first clamping end 119 and the serrated structure of the second clamping end 120 are meshed with each other and act together on the object to be contacted, so that the object to be contacted is tightly connected with the first clamping end 119 and the second clamping end 120, thereby preventing the object to be contacted from being separated from the electroplating fixture 10.

[0093] (2) The clamping member 123 is a concave-convex structure, and the concave-convex structure located at the first clamping end 119 matches the concave-convex structure located at the second clamping end 120; for example, the clamping surface of the first clamping end 119 is formed with a protrusion, and the clamping surface of the second clamping end 120 is formed with a pit that wraps the protrusion. When clamping the object to be contacted, the protrusion can carry the object to be contacted into the pit, so that the object to be contacted is tightly connected with the first clamping end 119 and the second clamping end 120, thereby preventing the object to be contacted from being separated from the electroplating fixture 10.

[0094] (3) The clamping member 123 is a magnetic structure, and the magnetic structure at the first clamping end 119 and the magnetic structure at the second clamping end 120 have opposite magnetic properties; for example, a first magnet is provided on the first clamping end 119, and a second magnet is provided on the second clamping end 120, and the magnetic properties of the first magnet and the second magnet are opposite. By providing the magnet, the time for the first clamping arm 101 and the second clamping arm 102 to change from an open state (the first clamping arm 101 and the second clamping arm 102 are separated from each other) to a closed state (the first clamping arm 101 and the second clamping arm 102 are close to each other) can be shortened, and the clamping force of the first clamping end 119 and the second clamping end 120 can be increased by the magnetic attraction of the magnet, so as to avoid the first clamping end 119 and the second clamping end 120 from loosening during the process of clamping the object to be contacted, thereby preventing the object to be contacted from falling off. Of course, a magnet can also be provided on the first clamping end 119, and the material on the second clamping end 120 is a metal material that can be attracted by the magnet.

[0095] In an achievable implementation, a rolling member 124 is provided at one end of the adjusting rod 103 away from the hinge shaft 106. The rolling member 124 is provided at one end of the adjusting rod 103 away from the hinge shaft 106, and the rolling member 124 can be a roller or other rolling parts, and the axis of the rolling member 124 is perpendicular to the axis of the adjusting rod 103.

[0096] In an achievable embodiment, the electroplating fixture 10 further includes a first connecting wire and a second connecting wire. The first connecting wire is connected between the first clamping end 119 and the negative electrode of the power supply, and / or the second connecting wire is connected between the second clamping end 120 and the negative electrode of the power supply, and the first clamping end 119 and the negative electrode of the power supply are connected at both ends of the first connecting wire, thereby realizing conduction between the negative electrode of the power supply and the first clamping end 119, and the second clamping end 120 and the negative electrode of the power supply are connected at both ends of the second connecting wire, thereby realizing conduction between the negative electrode of the power supply and the second clamping end 120, and when clamping the object to be contacted, conduction between the negative electrode of the power supply and the object to be contacted can be realized.

[0097] An embodiment disclosed in the present application further provides an electroplating device, which includes the electroplating fixture 10 in the above embodiment. The electroplating device is used to electroplate a cell so that a metal film is attached to the entire area or a part of the area on the surface of the cell.

[0098] In this embodiment, see the attached Fig.11 As shown, the electroplating equipment also includes a transmission device and a switching device. The transmission device is used to transmit the electroplating fixture 10 along the transmission path, and the switching device is arranged on the transmission path of the electroplating fixture 10 to drive the adjustment rod 103 to move so that the first clamping arm 101 and the second clamping arm 102 repeatedly approach or move away from each other.

[0099] Specifically, the switching device includes a switching member 50 extending along the transmission path, the switching member 50 having a first mating portion 501 and a second mating portion 502, and the first mating portion 501 and the second mating portion 502 have a height difference, so that when the electroplating fixture 10 repeatedly contacts the first mating portion 501 and the second mating portion 502, the electroplating fixture 10 switches between a closed state and an open state.

[0100] In the working state, the adjusting rod 103 is abutted against the switching member 50 through the rolling member 124 and can move along the switching member 50. In actual application, the first matching portion 501 is a plane, and the second matching portion 502 is an inclined surface that gradually recesses away from the first matching portion 501. That is to say, there is a height difference between the farthest ends of the first matching portion 501 and the second matching portion 502, and the height difference gradually increases from the connection between the first matching portion 501 and the second matching portion 502 to the farthest end of the second matching portion 502.

[0101] During the electroplating process of the electroplating equipment on the battery cell, the support seat 107 of the electroplating fixture 10 is driven by the transmission device to move along the transmission direction, and the adjusting rod 103 is moved on the switching member 50 through the rolling member 124. Specifically, during the transmission of the support seat 107, the adjusting rod 103 is driven by the support seat 107 to move along the transmission direction. Since the rolling member 124 of the adjusting rod 103 is located on the switching member 50, when the rolling member 124 moves to the first matching portion 501 via the second matching portion 502, the adjusting rod 103 will move in the first direction 30 under the height difference between the first matching portion 501 and the second matching portion 502, so that The first clamping arm 101 and the second clamping arm 102 rotate relative to the support seat 107 respectively, and the first clamping end 119 and the second clamping end 120 are relatively opened, that is, the electroplating fixture 10 remains in an open state; when the electroplating fixture 10 gradually approaches the position of the contacted part 20, the rolling part 124 moves to the second matching part 502 through the first matching part 501. At this time, under the action of the height difference and the elastic component 114, the adjusting rod 103 moves toward the second direction 40, and the first clamping end 119 and the second clamping end rotate relative to the support seat 107 respectively, and the first clamping end 119 and the second clamping end 120 are relatively closed, so that the electroplating fixture 10 is converted to a closed state.

[0102] In practical applications, it should be ensured that the switching state of the electroplating fixture 10 corresponds to the setting position of the contacted part 20, that is, the electroplating fixture 10 is in a closed state when it moves to the position of the contacted part 20, and can be in an open state at other times. Specifically, since the electroplating fixture 10 is in an open state when it moves to the first matching part 501, and is in a closed state when it moves to the second matching part 502, when the switching part 50 arranges the positions of the first matching part 501 and the second matching part 502, it is necessary to ensure that the second matching part 502 is located below the conductive line. Since the second mating portion 502 is an inclined structure, the rolling element 124 will gradually close when it moves from the first mating portion 501 to the second mating portion 502. To avoid the situation where the electroplating fixture 10 cannot clamp the part to be contacted 20, the position of the part to be contacted 20 should be located at the lowest point of the second mating portion 502 or other pre-test point (the pre-test point is the position where the first clamping end 119 and the second clamping end 120 are close to each other and can clamp the part to be contacted 20 during the movement of the electroplating fixture 10 along the second mating portion 502).

[0103] In order to ensure continuous and stable electrical conduction of the battery cells being transmitted during the electroplating process, the switching element 50 can also be electrically connected to the negative pole of the power supply. The rolling element 124 is made of a conductive material. When the rolling element 124 contacts the switching element 50, the electrical energy it obtains can be transmitted to the contacted element 20 via the conductive wire.

[0104] It can be seen that the electroplating fixture 10 provided in the present application realizes the opening and closing of the electroplating fixture 10 by axially moving the adjusting rod 103 so that the first clamping arm 101 and the second clamping arm 102 move closer or farther away under the drive of the linkage component. Since the axial movement is easier to control, the electroplating fixture 10 can achieve higher precision and stability by axial opening and closing than by lateral opening and closing, which is conducive to accurate and stable clamping. In addition, when the electroplating fixture 10 clamps the contact part 20, it can also realize electrical conduction to it to improve the stability of electrical conduction.

[0105] The present application also provides an electroplating device including an electroplating fixture 10, which can open and close the electroplating fixture 10 through a switching device, thereby automating the use of the electroplating fixture 10 and improving the electroplating efficiency.

[0106] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
