Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The following describes embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 1-7, embodiments of the present application provide a clamping assembly 100 that may be used to clamp a workpiece 500. The workpiece 500 may be a workpiece to be plated, including a metal plating member, a solar cell, a PCB flexible board, or a rectangular thin plate-like workpiece, etc., and the clamping assembly 100 is used to clamp the workpiece to be plated, so as to perform an electroplating process on the workpiece. In addition, the clamping assembly 100 can be applied to other situations and working conditions, which are not limited by the present application. Preferably, the clamping assembly of the embodiment is more suitable for being applied to the photovoltaic field, such as in the manufacturing process of a solar cell, and the solar cell is electroplated on a solar cell, and the solar cell has the characteristic of being fragile. The description of the specific technical scheme is provided below.

As shown in fig. 1-7, in some embodiments, the clamping assembly 100 includes a connector 110, a first conductive member 120, a second conductive member 130, and an elastic member 140.

The first conductive member 120 and the second conductive member 130 are respectively used for contacting with the workpiece 500, so that on one hand, two opposite sides of the workpiece 500 can be clamped to ensure that the workpiece 500 is stationary, and on the other hand, electric energy can be transmitted to the workpiece 500, thereby being convenient for electroplating treatment or other process treatment on the workpiece 500.

The first conductive member 120 is provided with a first clamping end 121, and the first clamping end 121 is used for contacting with the workpiece 500 and clamping the workpiece 500; accordingly, the second conductive member 130 is provided with a second clamping end 131, and the second clamping end 131 is used for contacting the workpiece 500 and clamping the workpiece 500. In the embodiment of the present application, the second clamping end 131 is opposite to the first clamping end 121, so that the same positions on two opposite sides of the workpiece 500 can be clamped, so as to ensure the clamping firmness and stability and prevent the workpiece 500 from moving randomly. Here, the above-mentioned relative arrangement may specifically include: the end surface of the first clamping end 121 and the end surface of the second clamping end 131 completely overlap, but may overlap in part.

The first conductive element 120 is connected to the connecting element 110, based on which the first conductive element 120 and the connecting element 110 can be moved synchronously, so as to adjust the position of the first conductive element 120 relative to the workpiece 500, and of course, the first conductive element 120 can be stationary synchronously, so as to ensure the stability of the first conductive element 120.

The first conductive element 120 may be fixed to the connecting element 110, for example, may be connected by welding, bonding, riveting, or the like, so as to ensure the connection firmness; the first conductive element 120 may also be detachably connected to the connecting element 110, for example, by fastening, screwing, sleeving, etc. to facilitate assembly and disassembly.

In addition, the connecting member 110 and the second conductive member 130 can move relatively, so that the first conductive member 120 can move relatively with the connecting member 110 and the second conductive member 130, and thus, the workpiece 500 can be clamped or released by the relative movement of the first conductive member 120 and the second conductive member 130, so as to facilitate the process, such as electroplating, on the workpiece 500. It should be understood that the connecting member 110 and the second conductive member 130 may be movable (movable) relatively, and there may be three ways, for example, the connecting member 110 is kept stationary and the second conductive member 130 moves, or the second conductive member 130 is kept stationary and the connecting member 110 moves, or both the connecting member 110 and the second conductive member 130 move. In this embodiment, the second conductive member 130 is fixedly connected to the fixing frame 200, and the connecting member 110 moves, and the connecting member 110 can drive the first conductive member 120 to move along with the connecting member 110 while moving, so that the first conductive member 120 moves relatively to the second conductive member 130, and the effect of clamping a workpiece such as a battery piece or releasing the battery piece is achieved, i.e. the effect of opening or closing the clamping point.

In order to ensure that the first conductive element 120 and the second conductive element 130 can stably clamp the workpiece 500, in the embodiment of the application, the elastic element 140 is elastically connected with the second conductive element 130 and the connecting element 110, and under the elastic action of the elastic element 140, the first clamping end 121 and the second clamping end 131 have a relatively close movement trend, so that the first conductive element 120 and the second conductive element 130 can be promoted to clamp the workpiece 500 from two sides, so as to ensure the stability and the firmness of clamping the workpiece 500, on the one hand, the firmness of clamping the workpiece 500 can be ensured, and on the other hand, the elastic element 140 can also play a role of elastic buffering, so as to prevent the workpiece 500 from being damaged due to too tight clamping; and, the electric energy is transferred to the workpiece through at least one of the first conductive member 120 and the second conductive member 130, so as to facilitate the process treatment, such as electroplating, on the workpiece. For example, when the clamping assembly is applied to the field of solar cells, the first conductive member 120 and the second conductive member 130 can transmit electric energy to two sides of a workpiece, that is, the first conductive member 120 and the second conductive member 130 are in contact with the solar cells for conducting electricity, so that double-sided electroplating of the cells is realized. Of course, when the clamping assembly is applied to a PCB flexible board or other workpieces to be plated, one or both of the first conductive member 120 and the second conductive member 130 may be in contact with the workpieces to achieve a single-sided or double-sided electroplating effect on the workpieces.

Based on the above arrangement, the embodiment of the application can realize the elastic clamping of the workpiece, and compared with the way of rigidly fixing the workpiece, the clamping assembly 100 in the application can ensure the firmness of clamping and the integrity of the workpiece.

Compared with a lever type mechanism adopted by a conventional electroplating clamp, the clamp is opened and closed, and the phenomenon that stress at a clamping point is uneven easily and a product to be plated is damaged easily exists. The contact surfaces of the clamping assembly 100 in this embodiment, where the first conductive member 120 and the second conductive member 130 are disposed at the clamping points, are parallel and opposite to each other when the product to be plated is clamped, so that the stress is more uniform, the damage to the product to be plated can be reduced or avoided, the product to be plated can be effectively or firmly clamped, and meanwhile, effective conduction can be realized, so that an excellent electroplating effect is achieved.

In the embodiment of the application, the first conductive element 120 may be provided with a first through hole 122, the connecting element 110 passes through the first through hole 122, and the first conductive element 120 and the connecting element 110 are relatively fixed. Further, the second conductive member 130 may be provided with a second through hole 132, and the connection member 110 passes through the second through hole 132. The connecting member 110 may have a structure with multiple sections of different diameters, for example, the connecting member 110 may include a three-section structure and a limiting end 112 sequentially arranged, wherein the diameter of the first section structure is the smallest and sequentially increases. The first through hole 122 of the first conductive element 120 may be connected to the first section structure of the connecting element 110, where a plane is provided on a side wall of the first section structure, so that the first conductive element 120 is prevented from rotating, and the stability and the firmness of connection are improved; the second through hole 130 of the second conductive element 130 may be connected to a third section structure of the connecting element 110, where a plane is disposed on a side wall of the third section structure, so that the second conductive element 130 is prevented from rotating, and the stability and the firmness of connection are improved.

Alternatively, in other embodiments, the first through hole 122 and the connecting member 110 may be in an interference fit, so as to ensure the connection between the first conductive member 120 and the connecting member 110 is firm and stable. In other embodiments, after the connection member 110 is mated with the first through hole 122, welding, bonding, etc. are performed, so that the connection between the first conductive member 120 and the connection member 110 can be ensured to be firm and stable; in some embodiments, after the first conductive element 120 passes through the first through hole 122, other limiting structures may be added to limit the first conductive element 120 on the connecting element 110, so as to ensure the connection firmness and stability between the first conductive element 120 and the connecting element 110, and further facilitate the disassembly and assembly; of course, the first through hole 122 may also be a threaded hole, and correspondingly, a section of the connecting piece 110 is of a screw structure, in this case, the first conductive piece 120 may be connected with the connecting piece 110 in a threaded manner, which not only can ensure stability and firmness of connection, but also can facilitate disassembly and assembly.

In a more specific embodiment, the side wall of the connecting member 110 may be provided with a first step surface 111, and one side surface of the first conductive member 120 abuts against the first step surface 111, and the clamping assembly 100 further includes a fastener 150, where the fastener 150 is detachably connected to the connecting member 110 and abuts against the other side surface of the first conductive member 120 facing away from the first step surface 111. Based on this kind of setting, can follow the opposite both sides of first electrically conductive piece 120 respectively butt first electrically conductive piece 120 through fastener 150 and first step face 111 to can be with first electrically conductive piece 120 spacing on connecting piece 110, guarantee the fastness and the stability of first electrically conductive piece 120, and make things convenient for the dismouting. In addition, the planar arrangement of the side wall of the first section structure of the connecting member 110 can also prevent the first conductive member 120 from rotating, thereby improving the firmness and stability of the first conductive member 120.

Alternatively, the fastener 150 may be a nut, and accordingly, the connecting member 110 is provided with a section of screw, so that the fastener 150 and the connecting member 110 may be in threaded engagement, which has a simple structure and is convenient for disassembly and assembly. For example, one end of the connector 110 may be provided with an end screw that may be used to connect with a nut.

In another implementation, two fasteners 150 may be installed on the connecting member 110, where the two fasteners 150 respectively abut against the first conductive member 120 from two opposite sides of the first conductive member 120, so that not only the limitation of the first conductive member 120 can be realized, but also the relative positions of the first conductive member 120 and the connecting member 110 can be conveniently adjusted, so as to adapt to workpieces 500 with different sizes.

In the embodiment of the present application, the electric energy may be transmitted to the workpiece 500 via the first conductive member 120, or the electric energy may be transmitted to the workpiece 500 via the second conductive member 130, or, of course, the electric energy may be transmitted to the workpiece 500 via both the first conductive member 120 and the second conductive member 130, which may be specifically selected according to the actual working condition. For example, when double-sided plating is performed on a solar cell, it is necessary to make both the first conductive member 120 and the second conductive member 130 contact with the cell to conduct electricity.

To facilitate wiring when electrical energy is transferred to the workpiece 500 through the first conductive member 120, the clamping assembly 100 may further include a conductive block 160, the conductive block 160 being disposed on the connector 110 and connected between the fastener 150 and the first conductive member 120. Based on this, the external connection terminal 180 may be connected with the conductive block 160, so that the external connection terminal 180 is connected with the first conductive member 120 through the conductive block 160 to facilitate the transmission of electric power to the first conductive member 120. Specifically, on one hand, the external power source may be connected to the hanging member 400 in the hanger, the hanging member 400 is connected to the fixing frame 200, the fixing frame 200 is connected to the connection terminal 180 through a wire, the connection terminal 180 is connected to the conductive block 160, and the conductive block 160 is connected to the first conductive member 120; thus, the external power source transmits power to the hanger 400, the hanger 400 transmits power to the fixing frame 200, the fixing frame 200 transmits power to the connection terminal 180 through the wire, the connection terminal 180 transmits power to the conductive block 160, the conductive block 160 transmits power to the first conductive member 120, and then the first conductive member 120 transmits power to one side of the battery plate. On the other hand, the external power source is connected with the hanging piece 400 in the hanger, the hanging piece 400 is connected with the fixing frame 200, and the fixing frame 200 is connected with the second conductive piece 130; thus, the external power source transmits power to the hanger 400, the hanger 400 transmits power to the holder 200, the holder 200 transmits power to the second conductive member 130, and then the second conductive member 130 transmits power to the other side of the battery cell.

Alternatively, the side wall of the conductive block 160 may be provided with a fixing hole, and the external connection terminal 180 may be connected in the fixing hole to secure connection and good electrical conductivity. Of course, the external connection terminal may be pressed between the conductive block 160 and the first conductive member 120 by the conductive block 160, and the connection firmness and good conductivity may be ensured as well.

The conductive block 160 may be provided with a hole, the connecting piece 110 passes through the hole, the conductive block 160 is extruded by connecting the fastener 150 and the connecting piece 110, and the first conductive piece 120 is extruded by the conductive block 160, so that the conductive piece is well contacted with the first conductive piece 120, and the first conductive piece 120 is limited, so that the stability and the firmness of the first conductive piece 120 are improved.

In other embodiments, the conductive block 160 may be provided with a threaded hole, and accordingly, the connecting member 110 is provided with a threaded section, so that the conductive block 160 and the connecting member 110 may be screwed, thereby facilitating disassembly.

Thus, the first conductive member 120 is a component directly contacting the workpiece 500, and the conductive block 160 is a component mechanically connected and fastened to the connecting member 110 by the external connection terminal 180, and is also a component participating in fastening the first conductive member 120. The connector 110 presents an interface between the first step and the second step, i.e., the first step surface 111, and a fastener 150, such as a nut, secures the conductive block 160 and the first conductive member 120 between the interface such that they are secured with the connector 110. The fastener 150, such as a nut, the conductive block 160, and the first conductive member 120, may follow the movement of the connection member 110.

To achieve the relative movement of the first conductive element 120 and the second conductive element 130, the second conductive element 130 may be provided with a second through hole 132, and the connection element 110 passes through the second through hole 132 and is movable with respect to the second through hole 132. Based on this arrangement, the connecting member 110 and the first conductive member 120 connected thereto can be moved relative to the second conductive member 130, such that the first conductive member 120 is relatively close to the second conductive member 130 to clamp the workpiece 500, or such that the first conductive member 120 is relatively far from the second conductive member 130 to release the workpiece 500. It should be noted that, the second conductive element 130 may be fixed, for example, the second conductive element 130 may be connected with other fixed structures, and the first conductive element 120 may move along with the connecting element 110, so that the first conductive element 120 approaches or moves away from the second conductive element 130; of course, it is also possible that the connecting member 110 and the first conductive member 120 are fixed, and the second conductive member 130 is connected to other power mechanisms, so that the second conductive member 130 is close to or far from the first conductive member 120; alternatively, both the first conductive member 120 and the second conductive member 130 may be movable to improve efficiency of approaching or separating from each other.

In order to realize the limiting function on the elastic member 140, a limiting end 112 is disposed at one end of the connecting member 110 adjacent to the second conductive member 130, the elastic member 140 is sleeved on the outer side of the connecting member 110, one end of the elastic member 140 is connected with the fixing frame 200, and the other end of the elastic member 140 is connected with the limiting end 112. Based on this arrangement, when the elastic member 140 is in the compressed state, under the elastic force of the elastic member 140, the limiting end 112 can be pushed to drive the connecting member 110 and the first conductive member 120 to approach the second conductive member 130, so as to clamp the workpiece 500. It should be noted that, the elastic force generated by the elastic member 140 is a flexible force, so that the workpiece 500 is not damaged even if the first conductive member 120 and the second conductive member 130 clamp the workpiece 500, and the integrity of the workpiece 500 is ensured.

In other embodiments, the elastic member 140 may be further connected between the first conductive member 120 and the second conductive member 130 to generate a tensile force, and the first conductive member 120 and the second conductive member 130 may be relatively close to each other under the tensile force of the elastic member 140 to clamp the workpiece 500.

Alternatively, the elastic member 140 may be a spring, such as a compression spring, a tension spring, a rubber band, etc., and may have other elastic structures, and the type of the elastic member 140 is not particularly limited in the present application.

In the embodiment of the present application, the clamping assembly 100 may further include a limiting member 170, where the limiting member 170 is disposed on the connecting member 110 and located between the first conductive member 120 and the second conductive member 130, and the limiting member 170 is movable relative to the connecting member 110 in a direction in which the first conductive member 120 and the second conductive member 130 move relative to each other. The elastic member 140 may be limited between the limiting head 112 and the fixing frame 200 by the limiting head 112 and the limiting member 170 of the connecting member 110. The limiting member 170 may be used to control the maximum extent of extension of the elastic member 140, such as a spring, when it is released after being compressed, to ultimately control the distance between the first conductive member 120 and the second conductive member 130 or the degree of compression of the workpiece to be plated.

Through setting up the locating part 170, can carry out the spacing to the relative movement distance of connecting piece 110 for second electrically conductive piece 130 to guarantee that the relative position parameter between first electrically conductive piece 120 and the second electrically conductive piece 130 that has adjusted can not change, and through adjusting the position of locating part 170 on connecting piece 110, can adapt to the relative position relation between first electrically conductive piece 120 and the second electrically conductive piece 130 under the different parameter condition, thereby can adapt to the centre gripping to different sizes work piece 500.

Under the actual working condition, when an external force is applied to the connecting piece 110, the elastic action of the elastic piece 140 can be overcome, so that the connecting piece 110 and the first conductive piece 120 are relatively far away from the second conductive piece 130, and the clamping action on the workpiece 500 is relieved; when the external force is released, under the action of the elastic force of the elastic member 140, the connecting member 110 and the first conductive member 120 are relatively close to the second conductive member 130, so as to clamp the workpiece 500, and the opening and closing degree of the first conductive member 120 and the second conductive member 130 can be changed by adjusting the position of the limiting member 170 on the connecting member 110, so as to adapt to clamping the workpieces 500 with different sizes, and when the position of the limiting member 170 is adjusted, the relative position parameters of the adjusted first conductive member 120 and second conductive member 130 can be prevented from being changed by the limiting member 170.
