The welding strip clamping mechanism comprises a mounting seat, a push plate, a translation driving part and a plurality of clamping jaw assemblies. The clamping jaw assemblies are arranged on the mounting base at intervals, each clamping jaw assembly comprises a first clamping jaw, a second clamping jaw and a spring, and the middle of each first clamping jaw and the middle of each second clamping jaw are rotationally connected to the mounting base. The push plate is slidably connected to the mounting base, and a pressing groove is formed in the push plate. When the translation driving part drives the push plate to move towards the clamping jaw assembly, the pressing grooves extrude the first ends of the first clamping jaws and the first ends of the corresponding second clamping jaws, so that the second ends of the first clamping jaws and the second ends of the corresponding second clamping jaws are opened. When the translation driving part drives the push plate to move away from the clamping jaw assembly, the pressing grooves release the first ends of the first clamping jaws and the first ends of the corresponding second clamping jaws, and the springs lose pressure and rebound so that the first clamping jaws can be clamped with the second ends of the corresponding second clamping jaws. According to the welding strip clamping mechanism, all the clamping jaw assemblies are driven by the push plate in a unified mode, and the structure of the welding strip clamping mechanism is simplified.

Description

Technical Field

[0001] The present application relates to the field of photovoltaic cell assembly production equipment, and specifically to a welding ribbon clamping mechanism and a welding ribbon shearing device. Background Art

[0002] When there is a defective cell in the battery string that needs to be replaced, the connecting solder strip between the defective cell and its adjacent cell needs to be cut off, and then the defective cell is removed from the battery string. The replacement cell with the solder strip is placed in the position vacated after the defective cell is removed, and the solder strip on the replacement cell is overlapped with the solder strip on the adjacent cell.

[0003] Depending on the location of the defective cell in the string (beginning, middle, or end of the string), the corresponding replacement cells are categorized as head replacement cells, middle replacement cells, and end replacement cells. The lengths of the solder ribbons extending from the cells may vary among the three types of replacement cells.

[0004] The solder ribbons on the upper and lower surfaces of pre-prepared cells extend out of the cell at the same length. Therefore, if the extended length of the solder ribbons on both sides of the cell does not meet the required length of the replacement cell, the solder ribbons on the cell must be cut to obtain a replacement cell of the desired type, and then the replacement cell must be loaded into the rework location.

[0005] When cutting the solder ribbons on a cell, the ribbon clamping mechanism first controls the ends of the ribbon, and then the ribbon cutting mechanism cuts the clamped ribbon. Existing ribbon clamping mechanisms each have a separate actuator for opening and closing the clamp assembly corresponding to each ribbon. This excessive number of actuators makes the clamping mechanism complex and expensive. Utility Model Content

[0006] In order to solve the above technical problems, the present application provides a welding ribbon clamping mechanism, which adopts the following technical solutions:

[0010] When the translation drive unit drives the push plate toward the plurality of clamping jaw assemblies to a first position, the pressure groove squeezes the first end of each first clamping jaw and the corresponding second clamping jaw, so that the second end of each first clamping jaw and the second end of the corresponding second clamping jaw open, and the spring is compressed;

[0011] When the translation drive unit drives the push plate away from the plurality of clamping jaw assemblies to move to the second position, the pressure groove releases the first end of the first clamping jaw and the corresponding second clamping jaw, and the spring loses pressure and rebounds, so that the second end of each first clamping jaw is clamped with the second end of the corresponding second clamping jaw to clamp the welding strip.

[0012] The solder ribbon clamping mechanism provided in the present application has all the clamping jaw assemblies thereon uniformly driven by a driving mechanism consisting of a translational driving part and a push plate. There is no need to configure a driving mechanism separately for each clamping jaw assembly, thereby reducing the structural complexity of the solder ribbon clamping mechanism and reducing the cost of the solder ribbon clamping mechanism.

[0013] In some embodiments, there is one pressing groove, which extends along the first direction and spans across all the clamping jaw assemblies; or, there are several pressing grooves along the first direction, each of which corresponds to a clamping jaw assembly.

[0014] There is only one pressing groove on the push plate, and the push plate drives all the clamping jaws through the pressing groove, which reduces the difficulty of making the pressing groove.

[0016] The first and second jaws of each clamping assembly are rotatably connected to the mounting base via a unified shaft, further simplifying the structural complexity and cost of the ribbon clamping mechanism provided by this application. The first and second jaws of each clamping assembly are connected to the mounting base via independent shafts, facilitating maintenance and replacement of each clamping assembly.

The mounting base is configured as a split structure consisting of a base and a jaw mounting base, which facilitates installation and maintenance of the jaw assemblies and push plate.

[0019] In some embodiments, a plurality of limiting grooves corresponding to the clamping jaw assemblies are arranged on the clamping jaw mounting seat at intervals along the first direction, and the middle portion of each clamping jaw assembly is located in the corresponding limiting groove.

[0020] Each clamping jaw assembly is located in a corresponding limiting groove, thereby limiting the clamping jaw assembly and preventing the clamping jaw assembly from being offset in the first direction.

[0021] In some embodiments, the jaw assembly further comprises a block, which is located between the first jaw and the second jaw and close to the second ends of the first jaw and the second jaw; the block is arranged on the inner wall of the first jaw or the second jaw, or the block is arranged on the mounting seat.

[0022] For welding strips of different thicknesses, the thickness of the blocking block can be adaptively set, so that the first clamping jaw and the second end of the second clamping jaw of the clamping jaw assembly can effectively clamp the welding strip when clamped together, and the welding strip will not be flattened and deformed due to excessive clamping force.

[0023] In some embodiments, a first pressure-bearing surface is formed on the upper surface of the first end of the first clamping jaw, and a second pressure-bearing surface is formed on the lower surface of the first end of the second clamping jaw. A first arc-shaped extrusion surface and a second arc-shaped extrusion surface are respectively formed at the notch of the pressure groove. The first arc-shaped extrusion surface is used to extrude the first pressure-bearing surface, and the first arc-shaped extrusion surface is used to extrude the second pressure-bearing surface; the first pressure-bearing surface is an inclined surface inclined upward along the forward direction of the push plate, and the second pressure-bearing surface is an inclined surface inclined downward along the forward direction of the push plate.

[0024] By implementing the above-mentioned settings on the first ends of the first clamping jaw and the second clamping jaw and the notch of the pressing groove, it can be ensured that the first ends of the first clamping jaw and the second clamping jaw slide smoothly along the first arc-shaped extrusion surface and the second arc-shaped extrusion surface of the pressing groove respectively, preventing jamming and reducing wear.

[0025] In some embodiments, the jaw assembly includes two springs disposed side by side along the second direction between the first end of the first jaw and the first end of the second jaw.

[0026] There are two springs, which can increase the clamping force of the clamping jaw assembly on the welding strip.

[0052] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0053] like Figures 1 to 6 As shown, the solder ribbon clamping mechanism 10 in the embodiment of the present application includes a mounting base 1, a push plate 2, a translation drive portion 3 and a plurality of (for example, 16 in the figure) clamping jaw assemblies 4.

[0054] A plurality of clamping jaw assemblies 4 are arranged on the mounting base 1 at intervals along a first direction (such as the X-axis direction), and each clamping jaw assembly 4 is used to clamp a welding strip. The clamping jaw assembly 4 includes a first clamping jaw 41, a second clamping jaw 42 and a spring 43, wherein the middle part of the first clamping jaw 41 and the middle part of the second clamping jaw 42 are both rotatably connected to the mounting base 1, and the spring 43 abuts between the first end of the first clamping jaw 41 and the first end of the second clamping jaw 42, and the second end of the first clamping jaw 41 and the second end of the second clamping jaw 42 are clamping ends.

[0055] The push plate 2 is slidably connected to the mounting base 1 and is connected to a translation drive unit 3 provided on the mounting base 1. The translation drive unit 3 is used to drive the push plate 2 to move toward or away from a number of clamping jaw assemblies 4 along a second direction (such as the Y-axis direction). A pressing groove 21 is provided on the push plate 2, which is open toward the number of clamping jaw assemblies 4. The second direction is perpendicular to the first direction.

[0056] When the translation drive unit 3 drives the push plate 2 to move toward the plurality of clamping jaw assemblies 4 to the first position, the pressure groove 21 squeezes the first end of each first clamping jaw 41 and the corresponding second clamping jaw 42, so that the second end of each first clamping jaw 41 and the second end of the corresponding second clamping jaw 42 are opened, and the spring 43 is compressed.

[0057] When the translation drive unit 3 drives the push plate 2 to move away from the plurality of clamping jaw assemblies 4 to the second position, the pressure groove 21 releases the first end of the first clamping jaw 41 and the corresponding second clamping jaw 42, and the spring 43 loses pressure and rebounds, so that the second end of each first clamping jaw 41 is clamped with the second end of the corresponding second clamping jaw 42 to clamp the welding strip.

[0058] The working process of the soldering ribbon clamping mechanism 10 in the embodiment of the present application is as follows:

[0059] First, the translation drive unit 3 is controlled to drive the push plate 2 to move toward the plurality of jaw assemblies 4 to the first position, so that the pressure groove 21 squeezes the first end of the first jaw 41 and the second jaw 42 of each jaw assembly 3, thereby making the second end of the first jaw 41 and the second jaw 42 of each jaw assembly 4 open. At the same time, the spring 43 in each jaw assembly 3 is compressed.

[0060] Subsequently, the mounting base 1 is controlled to move toward the welding ribbon group to be clamped until each welding ribbon in the welding ribbon group enters between the second ends of the first clamping jaw 41 and the second clamping jaw 42 of one clamping jaw assembly 4 in a one-to-one correspondence.

[0061] Finally, the translation drive unit 3 is controlled to drive the push plate 2 to move away from the plurality of clamping jaw assemblies 4 to the second position, so that the pressure groove 21 releases the first end of the first clamping jaw 41 and the second clamping jaw 42 of each clamping jaw assembly 4. At the same time, the spring 43 loses pressure and rebounds, pushing the second end of the first clamping jaw 41 and the second clamping jaw 42 of each clamping jaw assembly 4 to clamp together to clamp the corresponding welding strip.

[0062] It can be seen that in the solder ribbon clamping mechanism 10 provided in the embodiment of the present application, all the clamping jaw assemblies 4 thereon are uniformly driven by the driving mechanism composed of the translation driving part 3 and the push plate 2, and there is no need to configure a separate driving mechanism for each clamping jaw assembly, thereby simplifying the structural complexity of the solder ribbon clamping mechanism 10 and reducing the cost of the solder ribbon clamping mechanism 10.

[0063] like Figure 6As shown, optionally, a single pressing groove 21 is provided, extending along the first direction and spanning all the clamping jaw assemblies 4. Only one pressing groove 21 is provided on the push plate 2, and the push plate 2 implements a unified drive for all the clamping jaw assemblies 4 via the single pressing groove 21 thereon, thereby simplifying the difficulty of manufacturing the pressing groove 21.

[0064] Of course, the plurality of pressing grooves 21 may be provided along the first direction, with each pressing groove 21 corresponding to a clamping jaw assembly 4. The push plate 2 drives the second ends of the plurality of clamping jaw assemblies 4 to open or close in a one-to-one correspondence via the plurality of pressing grooves 21 thereon, thereby making the control of each clamping jaw assembly 4 more targeted.

[0065] Optionally, a rotating shaft 5 extending along a first direction is provided on the mounting base 1, and the middle portion of the first clamping jaw 41 and the middle portion of the second clamping jaw 42 of each clamping jaw assembly 4 are both rotatably connected to the mounting base 1 via the rotating shaft 5. The first clamping jaw 41 and the second clamping jaw 42 of each clamping jaw assembly 4 are rotatably connected to the mounting base 1 via the unified rotating shaft 5, further simplifying the structural complexity and cost of the welding ribbon clamping mechanism in the embodiment of the present application.

[0066] Of course, each jaw assembly 4 includes an independent rotating shaft 5, which is arranged on the mounting base 1 along the first direction. The middle portion of the first jaw 41 and the middle portion of the second jaw 42 of each jaw assembly 4 are rotatably connected to the corresponding rotating shaft 5. The first jaw 41 and the second jaw 42 of each jaw assembly 4 are respectively connected to the mounting base 1 via the independent rotating shaft 5, which facilitates maintenance and replacement of each jaw assembly 4.

[0067] like Figures 1 to 2 As shown, optionally, the mounting base 1 includes a base 11 and a clamping jaw mounting base 12, wherein the clamping jaw mounting base 12 is mounted on the edge of the base 11 along a first direction, and the plurality of clamping jaw assemblies 4 are disposed on the clamping jaw mounting base 12. A guide rail 13 extending along a second direction is disposed on the base 11, and the push plate 2 is slidably connected to the guide rail 13 and is connected to the translation drive unit 3 mounted on the base 11.

[0068] The translation drive unit 3 drives the push plate 2 to translate along the guide rail 13 toward or away from each clamping jaw assembly 4, thereby ensuring the translation stability of the push plate 2 and preventing the push plate 2 from deviating. The mounting base 1 is set as a split structure including a base 11 and a clamping jaw mounting base 12, which facilitates the installation and maintenance of the clamping jaw assembly 4 and the push plate 2.

[0069] like Figure 1 and Figure 3 As shown, optionally, a plurality of limiting grooves 14 corresponding to the clamping jaw assemblies 4 are provided on the clamping jaw mounting base 12 at intervals along the first direction, and the middle portion of each clamping jaw assembly 4 is located in the corresponding limiting groove 14. The limiting groove 14 limits the corresponding clamping jaw assembly 4 and prevents the clamping jaw assembly 4 from being offset in the first direction.

[0070] like Figure 3 and Figure 5 As shown, the jaw assembly 4 optionally further includes a spacer block 44, which is located between the first jaw 41 and the second jaw 42 and near the second ends of the first jaw 41 and the second jaw 42. The spacer block 44 is disposed on the inner wall of the first jaw 41 or the second jaw 42. Of course, the spacer block 44 can also be disposed on the mounting base 1.

[0071] For welding strips of different thicknesses, the thickness of the blocking block 44 can be adaptively set so that the welding strip can be effectively clamped when the first clamping jaw 41 and the second end of the second clamping jaw 42 of the clamping jaw assembly 4 are clamped together, and the welding strip will not be flattened and deformed due to excessive clamping force.

[0072] like Figure 5 and Figure 6 As shown, optionally, a first pressure-bearing surface 411 is formed on the upper surface of the first end of the first clamping jaw 41, and a second pressure-bearing surface 412 is formed on the lower surface of the first end of the second clamping jaw 42. Correspondingly, a first arcuate extrusion surface 211 and a second arcuate extrusion surface 212 are formed at the notch of the pressure groove 21, respectively. The first arcuate extrusion surface 211 is used to compress the first pressure-bearing surface 411, and the first arcuate extrusion surface 212 is used to compress the second pressure-bearing surface 412. The first pressure-bearing surface 411 is an inclined surface that tilts upward along the forward direction of the push plate 2, while the second pressure-bearing surface 412 is an inclined surface that tilts downward along the forward direction of the push plate 2.

[0073] By implementing the above-mentioned settings on the first ends of the first clamping jaw 41 and the second clamping jaw 42, and the notch of the pressure groove 21, it can be ensured that the first ends of the first clamping jaw 41 and the second clamping jaw 42 slide smoothly along the first pressure-bearing surface 411 and the second pressure-bearing surface 412 of the pressure groove 21 respectively, preventing jamming and reducing wear.

[0074] like Figure 5 As shown, each clamping jaw assembly 4 optionally includes two springs 43, which are arranged side by side along the second direction between the first end of the first clamping jaw 41 and the first end of the second clamping jaw 42. Providing two springs 43 can increase the clamping force of the clamping jaw assembly 4 on the welding ribbon. Of course, in other embodiments, the number of springs 43 can also be one, three, or more.

[0075] like Figure 7 As shown, optionally, the solder strip clamping mechanism 10 in the embodiment of the present application further includes a driving module 6, and the mounting seat 1 is connected to the driving end of the driving module 6. The driving module 6 is used to drive the mounting seat 1 to translate and lift, so that the solder strip to be clamped can enter the corresponding clamping jaw assembly 4 and be clamped by the corresponding clamping assembly 4.

[0076] Optional, such as Figure 7 As shown, the driving module 6 includes a lifting driving part 61 and a translation driving part 62, wherein the lifting driving part 61 is connected to the movable part of the translation driving part 62, and the mounting base 1 is connected to the movable part of the lifting driving part 61, wherein the translation driving part 62 is used to drive the mounting base 1 to translate, and the lifting driving part 61 is used to drive the mounting base 1 to lift and lower.

[0077] like Figure 7 As shown, the embodiment of the present application further provides a welding ribbon shearing device, which includes a carrier 20, a welding ribbon shearing mechanism 30 and a welding ribbon clamping mechanism 10 provided in any of the above embodiments, wherein:

[0078] The supporting platform 20 is used to support the battery cell 100 to be cut with a first side welding strip connected to the upper surface of the battery cell 100 and extending outward from the first side of the battery cell. The lower surface of the battery cell 100 is connected to a second side welding strip extending outward from the second side of the battery cell 100.

[0079] The solder ribbon clamping mechanism 10 is located on one side of the carrier 20 . The solder ribbon clamping mechanism 10 is used to clamp the end of the first side solder ribbon or the second side solder ribbon on the battery cell 100 close to the solder ribbon clamping mechanism 10 .

[0080] The welding strip shearing mechanism 30 is used to shear the end of the clamped first-side welding strip or the second-side welding strip.

[0081] It can be seen that through the cooperation of the supporting platform 20, the solder ribbon cutting mechanism 30 and the solder ribbon clamping mechanism 10, the solder ribbon cutting device in the embodiment of the present application realizes the cutting of the end of the solder ribbon on the battery cell, thereby preparing the required type of replacement battery cell for battery string repair.

Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and that all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, not by the above description in the embodiments. Furthermore, the embodiments mentioned in the present application are not limited to being implemented individually, and some embodiments can also be implemented in combination.
