Specifically, the present embodiment will be explained specifically by taking the connector 5 as an example of a fastening screw. As shown in fig. 4, a sinking groove 22 is formed in the moving member 2, a first mounting hole 21 is formed in the sinking groove 22, and after a fastening screw passes through the second mounting hole 31 and the first mounting hole 21 to connect the first clamping member 3 and the moving member 2 together, a nut of the fastening screw is embedded in the sinking groove 22 of the moving member 2, and a surface of the nut is lower than a surface of the moving member 2.

Alternatively, referring to fig. 1 and 5, the moving element 2 is a shaft rod, and the shaft rod is rotatably connected with the fixed carrier plate 1; the first clamping piece 3 comprises a carrier 32, a cantilever 33 and a probe 34, one end of the cantilever is fixedly connected with the carrier 32, and the other end of the cantilever is fixedly connected with the probe 34; the probes 34 are perpendicular to the carrier 32 and the cantilever 33, respectively; the carrier 32 is provided with the second mounting hole 31, and the first mounting hole 21 and the second mounting hole 31 detachably connect the shaft with the carrier 32 through a connector 5.

Specifically, as shown in fig. 1 and 5, the shaft rod is rotatably connected to the fixing carrier plate 1, and the rotation of the shaft rod drives the first clamping member 3 to move relative to the second clamping member 4, so as to clamp and loosen the solar cell. The first clamping member 3 comprises a carrier 32, a cantilever 33 and a probe 34, wherein one end of the cantilever 33 is fixedly connected with the carrier 32, and the other end is fixedly connected with the probe 34, so that the carrier 32, the cantilever 33 and the probe 34 are integrated into a whole structure. The carrier 32 is provided with a second mounting hole 31, and the connecting piece 5 detachably connects the shaft and the carrier 32 together by means of the first mounting hole 21 and the second mounting hole 31, so that the connecting position of the carrier 32 on the shaft can be adjusted, and the adjustment of the clamping position of the first clamping piece 3 is realized. When the solar cell is clamped for electroplating, the probe 34 contacts the solar cell, and current can be used for electroplating the solar cell through the probe 34.

In one embodiment, the cantilever 33 and the probe 34 are integrally connected, for example, welded together, and the two are not detachable, and the first clamping members 3 with different specifications correspond to the cantilever 33 and the probe 34 with different specifications, so that the assembling process of the cantilever 33 and the probe 34 can be omitted, the production cost can be effectively reduced, and if the first clamping members 3 are misaligned, the cantilever 33 and the probe 34 can be adjusted simultaneously. In another embodiment, the cantilever 33 and the probe 34 are separately connected, for example, connected together by a screw, the cantilever 33 and the probe 34 can be matched together by a screw, and the two can be detached, in this way, if the first clamping member 3 has a misaligned condition, the probe 34 can be detached separately for adjustment, the adjustment precision is higher, and the replacement of the probe 34 is simpler and more convenient. The embodiment is not limited with respect to the specific connection manner of the cantilever 33 and the probe 34.

Similarly, the structure of the second clamping member 4 may be the same as that of the first clamping member 3, and the second clamping member 4 may include a carrier, a cantilever and a probe, one end of the cantilever is fixedly connected with the carrier, and the other end is fixedly connected with the probe. The carrier is provided with a fourth mounting hole, and the connecting piece 5 detachably connects the fixing carrier plate 1 and the carrier together by means of the third mounting hole and the fourth mounting hole, so that the connecting position of the carrier on the fixing carrier plate can be adjusted, and the clamping position of the second clamping piece 4 can be adjusted.

Alternatively, referring to fig. 7, the cantilever 33 is connected to a side of the shaft close to the fixed carrier 1.

Specifically, as shown in fig. 7, to solve the problems in the previous embodiments, a cantilever 33 may be connected to a side of the shaft rod close to the fixed carrier plate 1. Similarly, the end of the cantilever 33 connected to the probe 34 receives the force transmitted by the probe 34 along the direction of the probe 34 and away from the solar cell 7, and the end of the cantilever 33 connected to the shaft initially drives the cantilever 33 to rotate to a position parallel to the solar cell 7, so that the probe 34 can contact the solar cell 7, after a long time use, due to the forced slippage of the probe 34, after the cantilever 33 rotates to a position parallel to the solar cell 7, the shaft needs to continue to rotate clockwise to ensure that the probe 34 contacts the solar cell 7, and at this time, the cantilever 33 receives the tensile force applied by the shaft along the direction of the cantilever 33 and away from the probe 34, so as to reduce the degree of the cantilever 33 bending, even avoid the cantilever 33 bending, thereby reducing the slippage degree of the probe 34, so that the probe 34 vertically contacts the solar cell 7 for clamping, and effectively prolonging the service lives of the cantilever 33 and the probe 34.

Furthermore, since the cantilever 33 in this embodiment is connected to the side of the shaft close to the fixed carrier 1, when the cantilever 33 and the probe 34 are cleaned, the cantilever 33 is shielded by the shaft and is difficult to clean, so that a shaft seat can be provided to support the shaft. The height of the shaft seat can be set according to the height of the probe 34 in the first clamping piece 3, so that a gap is formed between the shaft rod supported by the shaft seat and the fixed carrier plate 1, the height of the gap is slightly larger than the sum of the heights of the first clamping piece 3 and the second clamping piece 4, the first clamping piece 3 and the second clamping piece 4 can effectively clamp the solar cell, the first clamping piece 3 and the second clamping piece 4 can be sufficiently cleaned under the separated condition, and the first clamping piece 3 is prevented from being corroded by residual electroplating solution.

Optionally, referring to fig. 5, the electroplating carrier further includes a cushion block 6, one surface of the cushion block 6 is welded to the carrier 32, and the other surface is fixedly connected to the shaft rod; the cushion block 6 is provided with a fifth mounting hole, the shape and the size of the fifth mounting hole are the same as those of the second mounting hole 31, and the shaft lever and the cushion block 6 are detachably connected through a connecting piece 5 by the first mounting hole 21, the second mounting hole 31 and the fifth mounting hole.

Specifically, if the shaft and the carrier 32 are directly connected, it can be seen from the foregoing embodiment that the insulating anticorrosive glue is filled in the connecting portion between the shaft and the carrier 32, the cantilever 33 is easily deformed during the continuous electroplating operation, and the deformation force generated after the deformation is applied to the shaft and the insulating anticorrosive glue at the connecting portion through the carrier 32, which may cause the insulating anticorrosive glue at the connecting portion to crack and fall off, so that the connecting portion between the shaft and the carrier 32 is corroded by the electroplating solution, even loses the insulating effect, and a leakage phenomenon occurs, thereby causing a safety accident. In view of this, as shown in fig. 5, a cushion block 6 is provided for the electroplating carrier, one surface of the cushion block 6 and the carrier 32 are welded into an integral structure, a fifth mounting hole is provided on the cushion block 6, the shape and the size of the fifth mounting hole are the same as those of the second mounting hole 31 on the carrier 32, and the shaft rod and the cushion block 6 are detachably connected together by the connecting piece 5 through the first mounting hole 21, the second mounting hole 31 and the fifth mounting hole, so that the carrier 32 and the shaft rod are connected through the cushion block 6. The carrier 32 is connected with the shaft rod through the cushion block 6, so that on one hand, the deformation force generated by the carrier 32 can be absorbed and buffered to a certain extent, and the deformation force is prevented from causing the fragmentation of the insulating anti-corrosion glue, thereby protecting the connecting part of the shaft rod and the carrier 32 from being corroded by electroplating liquid and improving the reliability of the connecting part. On the other hand, the plating solution can be prevented from accumulating between the carrier 32 and the shaft, and corrosion of the joint portion can be prevented.

Optionally, referring to fig. 5, a dovetail groove 61 is formed in an edge of the cushion block 6, and the dovetail groove 61 is filled with an insulating anticorrosive adhesive.

Specifically, as shown in fig. 5, a dovetail groove 61 is formed in the edge of the cushion block 6, and an insulating anticorrosive adhesive is filled in the dovetail groove 61, so that the corrosion resistance of the cushion block 6 can be improved, the connection relationship between the cushion block 6 and the shaft rod is strengthened, and the cushion block 6 and the shaft rod are more reliably connected, thereby preventing the cantilever 33 welded to the cushion block 6 from shaking when driving the probe 34 to clamp the solar cell, and ensuring the stability of the clamping force.

Optionally, referring to fig. 7, the electroplating carrier further includes a limiting and lifting mechanism 8, and the limiting and lifting mechanism 8 is connected to the cantilever 33 and is used for adjusting the cantilever 33 and the probe 34 to maintain a vertical state.

Specifically, as shown in fig. 6, when the solar cell 7 is clamped by the first clamping member 3 and the second clamping member 4 for electroplating, one end of the probe 34 of the first clamping member 3 is in contact with the solar cell 7, a clamping force is applied to the solar cell 7, and a reaction force generated by the solar cell 7 in the direction of the probe 34 is received. Since the other end of the probe 34 is fixedly connected to the cantilever 33, the force applied to the probe 34 is transmitted to the cantilever 33, and a force is applied to the cantilever 33 along the direction of the probe 34 and away from the solar cell 7. The other end of the cantilever 33 is connected to a side of the shaft rod away from the fixed carrier plate 1, initially, the shaft rod drives the cantilever 33 to rotate to a position parallel to the solar cell 7, and the probe 34 can contact the solar cell 7, however, after a long time use, due to the forced slippage of the probe 34, after the cantilever 33 rotates to a position parallel to the solar cell 7, the shaft rod needs to continue to rotate clockwise to ensure that the probe 34 contacts the solar cell 7, at this time, the cantilever 33 is subject to the extrusion force applied by the shaft rod along the cantilever 33 and towards the direction of the probe 34, so that the cantilever 33 bends towards the direction close to the solar cell 7, the cantilever 33 and the probe 34 are no longer perpendicular, and the situation that the clamping of the probe 34 is unstable or the cantilever 33 is damaged is easily caused.

To solve this problem, a lift mechanism 8 for limiting the position of the plating carrier is provided and connected to the arm 33, as shown in fig. 7. In one embodiment, during the rotation of the probe 34 and before the probe 34 contacts the solar cell 7, the limit lifting mechanism 8 lifts the cantilever 33 until the probe 34 contacts the solar cell 7, and the limit lifting mechanism 8 is removed. This approach can relieve the bending stress of cantilever 33 in advance, so that cantilever 33 and probe 34 are always perpendicular during rotation. In another embodiment, when the probe 34 does not start to rotate, the cantilever 33 is pulled reversely by the limit lifting mechanism 8 to make the cantilever 33 bend and deform reversely, and then during the rotation of the cantilever 33 and the probe 34, the forward bending stress applied to the cantilever 33 can be counteracted with the previous reverse bending stress, so that the cantilever 33 returns to the horizontal state and the probe 34 keeps vertical. In this embodiment, the reverse bending deformation refers to bending deformation in a direction away from the fixing carrier plate 1, and the forward bending deformation refers to bending deformation in a direction close to the fixing carrier plate 1. The two embodiments can reduce the sliding degree of the probe 34, so that the probe 34 vertically contacts with the solar cell 7 for clamping, and the service lives of the cantilever 33 and the probe 34 are effectively prolonged.

In addition, the other end of the limiting lifting mechanism 8 may be connected to the shaft rod, may also be connected to the fixed carrier plate 1, and may also be freely connected to other mechanisms, only the adjusting function of the cantilever 33 needs to be provided, and the specific connection mode is not limited in this embodiment.

Specifically, each of the plurality of clamping areas of the fixed carrier plate 1 can clamp one solar cell, each of the clamping areas is independent of each other and does not interfere with each other, the number of the clamping areas can be freely set as required, and the specific number is not limited in this embodiment.

Similarly, the total length of each second clamping member 4 is the same as the length of each clamping area corresponding to the second clamping member 4, the number of the cantilevers and the probes on each second clamping member 4 is determined according to the total length of the carrier, and when the second clamping members 4 are installed on two sides of each clamping area, the second clamping members can be installed only by assembling the fixed carrier plate 1 and the carrier, so that the installation time is effectively saved.

The design of the split shaft lever and the design of the integrated structure of the first clamping part 3 and the second clamping part 4 in the embodiment can enable each clamping area in the fixed carrier plate 1 to work independently without mutual interference, if a solar cell is electroplated, only two split shaft levers are needed to drive two sets of first clamping parts 3 to rotate, the split shaft levers are matched with two sets of corresponding second clamping parts 4 in one clamping area, other split shaft levers and clamping parts do not need to work, resource waste is avoided, abrasion between the first clamping part 3 and the second clamping part 4 is effectively reduced, and the service life of the whole electroplating carrier is prolonged. In addition, if the electroplating carrier in the embodiment is damaged, the local module can be integrally replaced and maintained, the operation is simple and convenient, and the maintenance difficulty is reduced.
