As shown in fig. 1-9, the plating carrier includes: an outer frame 10; the outer frame 10 comprises two end frames 11 arranged in parallel and two side frames 12 positioned between the two end frames 11; and a carrier unit 20; the bearing unit 20 is positioned in the outer frame 10 and is arranged between the two end frames 11; the carrying unit 20 includes: two rotating shafts 21 arranged in parallel; two ends of the rotating shaft 21 are respectively supported on the end frames 11 of the outer frame 10; at least two cell sheet carrying frames 22; the battery piece bearing frame 22 is arranged at intervals along the axial direction of the rotating shaft 21, the battery piece bearing frame 22 is provided with a clamping area 220 for clamping a battery piece, the battery piece bearing frame 22 comprises two sub side frames 221 opposite to each other along the axial direction of the rotating shaft 21, shaft seats 23 and fixed probe rows 24 are fixed on the two sub side frames 221, the shaft seats 23 are respectively and rotatably connected with the corresponding rotating shaft 21, and the fixed probe rows 24 extend into the clamping area 220 of the battery piece bearing frame 22 and are used for abutting against corresponding edges of the battery piece; the movable probe bank 25 is fixed on the rotating shaft 21 and is arranged corresponding to the fixed probe bank 24; the movable probe row 25 moves away from or close to the fixed probe row 24 as the rotating shaft 21 rotates, so as to unload or clamp the battery piece on the carrying unit 20.

In the embodiment of the present invention, because the two rotating shafts 21 are arranged in parallel, and two ends of each rotating shaft 21 are respectively supported on the end frames 11 of the outer frame 10, the shaft seats 23 and the fixed probe rows 24 are fixed on the two sub-side frames 221 of the battery piece carrying frame 22, and the shaft seats 23 are respectively rotatably connected with the corresponding rotating shafts 21, during the rotation of one rotating shaft 21, the rotating shaft 21 may have a tendency of driving the shaft seats 23 to rotate, and drive one sub-side frame 221 of the battery piece carrying frame 22 to rotate, so that the other sub-side frame 221 rotates, but the other rotating shaft 21 is supported on the two end frames 11 and fixed on the other sub-side frame 221 through the shaft seats 23, so that the other sub-side frame 221 can be fixed, so that the two sub-side frames 221 cannot rotate along with the rotating shaft 21 of the rotating shaft 21, so that the rotating shaft 21 can rotate relative to the shaft seats 23, that during the rotation of the rotating shaft 21, the wafer carrier frame 22 does not rotate and the fixed probe array 24 does not rotate. Since the movable probe bank 25 is fixed on the shaft seat 23 and is arranged corresponding to the fixed probe bank 24, during the rotation of the rotating shaft 21, the movable probe bank 25 moves away from or approaches the fixed probe bank 24 along with the rotation of the rotating shaft 21 to unload or clamp the battery piece. Specifically, when the battery piece is electroplated, the movable probe row 25 can be close to the fixed probe row 24 to clamp the battery piece, and after the electroplating of the battery piece is finished, the movable probe row 25 can be far away from the fixed probe row 24 to unload the battery piece. In the embodiment of the present invention, the battery plate carrying frame 22 is connected to the rotating shaft 21 through the shaft seat 23, so that the structure of the electroplating carrier is relatively simple, and the amount of liquid carried by the electroplating carrier is less when the battery plate is electroplated.

It should be noted that, in the embodiment of the present invention, as shown in fig. 4, the fixed probe row 24 may include a plurality of fixed cantilevers 241 and a plurality of fixed probes 242, the plurality of fixed cantilevers 241 are disposed on the cell sheet carrying frame 22 at intervals, each of the fixed cantilevers 241 includes two opposite ends, one end of the fixed cantilever 241 is connected to the cell sheet carrying frame 22, and the other end of the fixed cantilever 241 is connected to one end of the fixed probe 242.

In addition, in the embodiment of the present invention, when the shaft seat 23 is fixed on the sub-side frame 221 of the battery sheet carrying frame 22, the number of the shaft seats 23 may be set according to actual requirements, for example, two shaft seats 23 may be fixed on the sub-side frame 221 of one battery sheet carrying frame 22, and three shaft seats 23 may be fixed on one battery sheet carrying frame 22. The number of the shaft seats 23 is not limited herein.

In addition, the fixed probe 242 and the fixed cantilever 241 may be formed as an integral structure, and the fixed probe 242 may be welded to the fixed cantilever 241. The embodiments of the present invention are not limited herein.

In addition, in the embodiment of the present invention, in order to ensure the strength of the rotating shaft 21, the diameter of the rotating shaft 21 may be larger than a preset threshold, wherein the preset threshold may be set according to actual needs. For example, the preset threshold may be 8 mm, and in this case, the diameter of the rotating shaft 21 needs to be larger than 8 mm, and the diameter of the rotating shaft 21 may be 10 mm. The embodiment of the present invention is not limited herein with respect to the specific value of the diameter of the rotating shaft 21.

In addition, in some embodiments, as shown in fig. 1, 4 and 6, one end of the two end frames 11 is used for connecting with a hanger, the movable probe bank 25 includes a substrate 251, a plurality of cantilevers 252 extending from the substrate 251, and probes 253 fixed to the ends of the corresponding cantilevers 252, the substrate 251 is fixed on the rotating shaft 21, and the cantilevers 252 are arranged at intervals. The length of the probes 253 in different active probe rows 25 increases gradually in the direction from one end frame 11 to the other end frame 11, and the length of the probes 253 in the same active probe row 25 is the same.

When the rotating shaft 21 rotates, the movable probe bank 25 moves along with the rotation of the rotating shaft 21, and the cell sheet bearing frame 22 is kept still. However, because the cantilevers 252 extend from the substrate 251 and the probes 253 are fixed at the ends of the cantilevers 252, the substrate 251 is fixed on the rotating shaft 21, and two ends of the rotating shaft 21 are respectively supported on the two end frames 11, so that, in the process of rotating the rotating shaft 21, when the rotating shaft 21 is in a direction from one end frame 11, i.e. the end frame 11 hooked with the hanger, to the other end frame 11, the torque transmitted by the rotating shaft 21 is reduced, so that the distance between the movable probe row 25 and the fixed probe row 24 is gradually reduced along with the rotation of the rotating shaft 21, i.e. after the rotating shaft 21 rotates by a preset angle, in a direction from one end frame 11 to the other end frame 11, the distance between the movable probe row 25 and the fixed probe row 24 is gradually increased, so that the distance between the movable probe row 25 and the fixed probe row 24 may not reach the set distance, i.e. the effective distance for clamping the battery pieces, thereby affecting the clamping effect of the movable probe row 25 and the fixed probe row 24 for clamping the battery pieces, thereby affecting the electroplating effect of the battery piece.

When the fixed probe bank 24 includes the fixed cantilever 241 and the fixed probe 242, and the movable probe bank 25 includes the substrate 251, the cantilever 252 and the probe 253, at this time, the distance between the movable probe bank 25 and the fixed probe bank 24 is: the distance between the clamping end of probe 253 and the clamping end of fixed probe 242, the clamping end of movable probe 253 refers to the end of probe 253 that is not connected to cantilever 252, and the clamping end of fixed probe 242 refers to the end of fixed probe 242 that is not connected to fixed cantilever 241.

In the embodiment of the utility model, in the direction from one end frame 11 to the other end frame 11, the lengths of the probes 253 in different movable probe banks 25 are gradually increased in the direction from one end frame 11 to the other end frame 11, and the lengths of the probes 253 in the same movable probe bank 25 are the same, so that when the rotating shaft 21 rotates to enable the movable probe bank 25 to be close to the fixed probe bank 24 to clamp the battery piece, the distance between the movable probe bank 25 and the fixed probe bank 24 can be kept consistent, that is, the distance between the probes 253 and the fixed probes 242 of the fixed probe bank 24 can be kept consistent, so that the probes 253 and the fixed probes 242 can better clamp the battery piece, and the electroplating effect on the battery piece is improved.

It should be noted that, in the embodiment of the present invention, as shown in fig. 4, the probe 253 and the cantilever 252 may be an integrated structure, and of course, the movable probe 253 may also be welded on the movable cantilever 252, which is not limited herein.

In addition, in the embodiment of the present invention, the substrate 251 may be fixed to the rotating shaft 21 by: the substrate 251 may be coupled to the rotation shaft 21 by a screw, i.e., the substrate 251 may be detachably coupled to the rotation shaft 21. Of course, the substrate 251 may also be welded to the rotating shaft 21, so that the substrate 251 is fixedly connected to the rotating shaft 21, and the embodiment of the present invention is not limited herein.

In addition, in the embodiment of the present invention, the rotating shaft 21 may be rotated by a mechanical device, so that the rotating shaft 21 rotates, wherein a first end of the rotating shaft 21 may be supported on the two end frames 11, and the first end of the rotating shaft 21 is connected to the mechanical device, so that the mechanical device drives the rotating shaft 21 to rotate. In particular, the mechanical device may be an electric motor.

In addition, in some embodiments, the length of the probes 253 in the same active probe row 25 is increased, or the length of the probes 253 in the active probe row 25 near one end frame 11, i.e., near the end frame 11 connected to the hanger, is constant, and the length of the probes 253 in the active probe row 25 near the second end of the other end frame 11 is increased. That is, in the direction along one end frame 11, i.e., the end frame 11 connected to the hanger, toward the other end frame 11, one movable probe bank 25 may be used as a small unit, the length of the probes 253 in each movable probe bank 25 may be kept uniform, or the length of the probes 253 in each movable probe bank 25 may be increased. The embodiments of the present invention are not limited thereto.

Additionally, in some embodiments, the difference in length between the longest length probe 253 and the shortest length probe 253 is 0.5 millimeters.

When the difference between the length of the probe 253 having the longest length and the length of the probe 253 having the shortest length is 0.5 mm, it is ensured that the distance between the movable probe row 25 and the fixed probe row 24 is kept uniform even if the torque transmitted by the rotating shaft 21 becomes smaller when the rotating shaft 21 transmits the torque by itself in the direction from the first end to the second end of the outer frame 10.

Additionally, in some embodiments, as shown in fig. 4, shaft seat 23 may include a seat 231 and a connector 232. The base 231 is connected with the connecting piece 232, a rotating groove is formed in the connecting piece 232, the rotating shaft 21 is embedded in the rotating groove, and the base 231 is fixed on two sides of the battery piece bearing frame 22.

When the shaft seat 23 includes the base 231 and the connecting member 232, the base 231 is connected to the connecting member 232, and the connecting member 232 is provided with a rotating groove, at this time, the rotating shaft 21 can be embedded in the rotating groove, so that the rotating shaft 21 can rotate in the rotating groove, and in the rotating process of the rotating shaft 21, the connecting member 232 cannot move along with the rotation of the rotating shaft 21. In addition, the base 231 can be fixed on both sides of the battery piece carrying frame 22, and at this time, when the rotating shaft 21 rotates in the rotating groove, both the connecting member 232 and the base 231 are kept stationary, so that the battery piece carrying frame 22 is kept stationary, and thus, the effect that the battery piece carrying frame 22 is kept stationary in the rotating process of the rotating shaft 21 is achieved.

It should be noted that the connecting member 232 and the base 231 may be integrated through a die-casting process, and of course, the connecting member 232 may also be connected with the base 231 through a welding method, which is not limited herein. In addition, in the embodiment of the present invention, the base 231 may be detachably connected to the battery sheet carrying frame 22, specifically, the base 231 may be connected to the battery sheet carrying frame 22 by a screw, and of course, the base 231 may also be welded to the battery sheet carrying frame 22, which is not limited herein.

In addition, in the embodiment of the utility model, when the solar cell is clamped by the movable probe bank 25 and the cell carrying fixed probe bank 24 to plate the cell, the cell is usually placed in a plating solution, and the cell carrying frame 22 is electrified to make the fixed probe bank 24 have electric energy, so that ions in the plating solution can be attached to the surface of the cell to form an electrode on the cell. The battery sheet carrying frame 22 may be powered in different manners, and the following examples are specifically described:

In the axial direction along the rotating shaft 21, the base 231 includes a first connection end 2311 and a second connection end 2312 which are opposite, the first connection end 2311 is connected with the sub-end frame 222 of one cell carrying frame 22 in two adjacent cell carrying frames 22, the second connection end 2312 is connected with the sub-end frame 222 of the other cell carrying frame 22 in two adjacent cell carrying frames 22, the cell carrying frames 22 are conductors, and the two adjacent cell carrying frames 22 are electrically conductive through the shared shaft seat 23.

When the first connecting end 2311 of the base 231 is connected with the sub-end frame 222 of one battery piece carrying frame 22 in two adjacent battery piece carrying frames 22, and the second connecting end 2312 of the base 231 is connected with the other sub-end frame 222 of the two adjacent battery piece carrying frames 22, it is equivalent to that two adjacent battery piece carrying frames 22 share one shaft seat 23. When the shaft seat 23 can conduct electricity, at this time, it is equivalent to that two adjacent battery piece carrying frames 22 realize the electricity conduction through the shaft seat 23, so that the two adjacent battery piece carrying frames 22 can be electrified. In addition, when two adjacent battery piece bearing frames 22 share one shaft seat 23 for conducting, the number of the shaft seats 23 can be saved, and other conducting modes are avoided, so that the two adjacent battery piece bearing frames 22 are electrified, the structure of the electroplating carrier is simpler, and the liquid carrying amount of the electroplating carrier in the electroplating process can be reduced.

In addition, in the embodiment of the present invention, a conductive sheet (not shown) may be further disposed on the base 231. The first connection end 2311 is provided with a first connection hole, a first conductive fastener is arranged in the first connection hole and is in contact with the sub-end frame 222 of one cell piece bearing frame 22 in the two adjacent cell piece bearing frames 22, the second connection end 2312 is provided with a second connection hole, a second conductive fastener is arranged in the second connection hole and is in contact with the sub-end frame 222 of the other cell piece bearing frame 22 in the two adjacent cell piece bearing frames 22, and the conductive sheets are respectively connected with the first conductive fastener and the second conductive fastener.

In addition, the first conductive fastener and the second conductive fastener can fix the conductive sheet, so as to prevent the conductive sheet from being deviated or separated from the base 231.

In addition, in the embodiment of the present invention, as shown in fig. 2, when the shaft seat 23 includes a base 231 and a connecting member 232, at this time, the first connecting end 2311 of the base 231 may be provided with a first connecting hole, the second connecting end 2312 of the base 231 may be provided with a second connecting hole, and the base 231 is provided with a sinking groove, and the first connecting hole and the second connecting hole are located at the bottom of the sinking groove.

Insulating parts such as silica gel can be arranged in the sinking groove, so that the silica gel can shield the first conductive fastening part, the second conductive fastening part and the conductive part, and the conductive part is prevented from contacting with electroplating solution when the battery piece is electroplated, thereby influencing the electroplating effect of the battery piece.

The first conductive fastener and the second conductive fastener may be metal screws, but may also be other types, such as metal pins. The type of the first conductive fastener and the second conductive fastener is not limited herein.

Mode (2): as shown in fig. 8, the sub-frame 221 of one cell carrier frame 22 of the two adjacent cell carrier frames 22 is bent away from the clamping area 220 to extend out of the first conductive connecting member 30, and the sub-frame 221 of the other cell carrier frame 22 is bent out of the second conductive connecting member 40. The first conductive connecting member 30 is inserted into the second conductive connecting member 40 to energize the two adjacent cell carrying frames 22.
