Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

At present, in the production process of solar cells, bus bars need to be welded on the cell plates so as to fix the cell plates. The bus bar is generally a strip-shaped structure wound on the carrier tray, and when the bus bar is welded, the bus bar needs to be cut to a predetermined length and then transported to a fixed position for welding. Therefore, a bus bar welding apparatus for performing automatic cutting and welding of a bus bar has been proposed.

As shown in fig. 1, the present embodiment provides a bus bar welding apparatus including a first rack 100, a conveying device 200, and a transverse preparing device 300. Wherein, conveyor 200 sets up on first support body 100, and conveyor 200 is used for carrying horizontal busbar 1000 and vertical busbar 2000 to next station to realize the automatic transport of horizontal busbar 1000 and vertical busbar 2000 between different stations, be favorable to improving the work efficiency of busbar welding equipment. The transverse bus bar 1000 extends in the X direction (first direction), the vertical bus bar 2000 extends in the Y direction (second direction), the transverse preparing apparatus 300 is disposed on the first rack 100, and the transverse preparing apparatus 300 is used to prepare the transverse bus bar 1000 and transfer it onto the conveying apparatus 200. The transverse preparation device 300 can realize automatic preparation of the transverse bus bar 1000, and is beneficial to improving the working efficiency of bus bar welding equipment. Illustratively, the X-direction and the Y-direction are perpendicular to each other according to the relative positions of the lateral bus bar 1000 and the vertical bus bar 2000 to which the battery assembly is welded.

The bus bar welding equipment is compact in structure, the conveying device 200 penetrates through the whole bus bar welding equipment and only moves through the conveying device 200, communication of all processes is achieved, and the structure is simplified.

As shown in fig. 2 and 3, specifically, the transverse bus bar 1000 and the vertical bus bar 2000 are integrally a bus bar body, and the transverse bus bar 1000 in the bus bar body is plural according to the requirement. Illustratively, the transverse bus bars 1000 may include three or four, which the operator selectively sets as desired.

With reference to fig. 1, in order to improve the efficiency of manufacturing the transverse bus bar 1000, the transverse manufacturing devices 300 include two sets of the transverse manufacturing devices 300, which are disposed opposite to each other, so that the two transverse bus bar 1000 can be manufactured at the same time, thereby improving the work efficiency of the bus bar welding apparatus.

As shown in fig. 1, in operation, if four lateral bus bars 1000 are required, two lateral preparing apparatuses 300 respectively prepare two lateral bus bars 1000, so as to reduce half the time between the preparation of the lateral bus bars 1000, thereby greatly improving the working efficiency. Of course, if three transverse bus bars 1000 are required, one transverse preparation device 300 prepares one transverse bus bar and the other transverse preparation device 300 prepares two transverse bus bars 1000, which is beneficial to reduce the preparation practice by one third and can also achieve the purpose of improving the efficiency of preparing the transverse bus bars 1000.

With continued reference to fig. 1, further, the lateral preparation device 300 includes a lateral preparation mechanism 310 and a first transfer mechanism 320. Wherein the transverse preparing mechanism 310 is used for preparing the transverse bus bar 1000, the first transferring mechanism 320 can transfer the transverse bus bar 1000 prepared by the transverse preparing mechanism 310 onto the conveying device 200, so as to automatically prepare and transfer the transverse bus bar 1000.

The detailed structure of the first transfer mechanism 320 will now be described with reference to fig. 4.

As shown in fig. 4, the first transfer mechanism 320 includes a seventh frame 321, a fourth driving member 322, and a third grabbing assembly 323. The seventh frame body 321 is disposed on the first frame body 100, the fourth driving member 322 is disposed on the seventh frame body 321, the third grabbing assembly 323 is disposed at an output end of the fourth driving member 322, and the fourth driving member 322 can drive the third grabbing assembly 323 to move in a direction approaching to the transverse bus bar 1000 or away from the transverse bus bar 1000, so as to achieve the purpose of grabbing the transverse bus bar 1000.

With continued reference to fig. 4, in particular, the third grabbing assembly 323 comprises a grabbing bracket 3231 and a grabbing piece 3232, the grabbing bracket 3231 is connected with the output end of the fourth driving piece 322, and the grabbing piece 3232 is disposed on the grabbing bracket 3231 for grabbing the transverse bus bar 1000. Specifically, the grasping member 3232 is communicated with a vacuum generating device, and grasps the transverse bus bar 1000 by a vacuum adsorption method, thereby being advantageous to ensure stability in grasping the bus bar.

With continued reference to fig. 4, the first transfer mechanism 320 further includes a fifth driving member 324 and a fourth guiding assembly 325. The fifth driving member 324 is disposed on the first frame 100, the third wire guiding assembly is disposed between the first frame 100 and the seventh frame 321, and the seventh frame 321 is disposed at an output end of the fifth driving member 324, so that the fifth driving member 324 can drive the seventh frame 321 to reciprocate along a direction in which the transverse preparation mechanism 310 moves toward the conveying device 200, and thus the prepared transverse bus bar 1000 can be transferred to the conveying device 200.

Referring to fig. 4, specifically, the fourth guiding assembly 325 includes a third guiding rail and a third sliding block, the third guiding rail is disposed along the Y direction, the third sliding block is slidably connected to the third guiding rail, the third guiding rail is disposed on the first frame 100, and the third sliding block is disposed on the seventh frame 321, so as to improve the stability of the movement of the seventh frame 321 along the Y direction and avoid the occurrence of jamming.

It can be understood that, since the two sets of the transverse preparation mechanisms 310 are provided, in order to ensure the transfer efficiency, the two sets of the first transfer mechanisms 320 are also provided, and the two sets of the first transfer mechanisms 320 simultaneously transfer the transverse bus bars 1000 prepared by the two transverse preparation mechanisms 310, which is beneficial to improving the working efficiency.

As shown in fig. 2 to 4, in addition, in the conventional battery module, it is generally necessary to weld three or more lateral bus bars 1000. In order to further improve the transferring efficiency, two sets of first transferring mechanisms 320 are correspondingly arranged on each set of transverse preparation mechanisms 310. When four transverse bus bars 1000 are needed, two transverse bus bars 1000 are prepared by each group of transverse preparation mechanisms 310, and after the transverse preparation mechanisms 310 complete two transverse bus bars 1000, the two first transfer mechanisms 320 can transfer the transverse bus bars simultaneously, so that the transfer efficiency is further improved. It is understood that when three transverse bus bars 1000 are to be prepared, one of the transverse preparation mechanisms 310 is prepared in two, the other transverse preparation mechanism 310 is prepared in one, and then the transverse bus bars 1000 are transferred, one of the two first transfer mechanisms 320 of one set is operated simultaneously, and only one of the two first transfer mechanisms 320 of the other set is required to be operated. This first transfer mechanism 320 work is nimble, and the suitability is strong, and is favorable to improving work efficiency.

As shown in fig. 5 to 6, the lateral preparing apparatus 300 further includes a transfer platform 330. The detailed structure of the centering stage 330 will now be described with reference to fig. 5 to 6.

As shown in fig. 5, the transfer platform 330 is disposed between the transverse preparation mechanism 310 and the conveying device 200, and the transfer platform 330 is used for carrying the transverse bus bars 1000 prepared by the transverse preparation mechanism 310, so as to wait for the transverse preparation mechanism 310 to prepare other transverse bus bars 1000, and then the first transfer mechanism 320 picks all the transverse bus bars 1000 from the transfer platform 330, so that when the first transfer mechanism 320 transfers the transverse bus bars 1000, the transverse preparation mechanism 310 can still prepare the transverse bus bars 1000, so that the preparation work of the transverse preparation mechanism 310 and the transfer action of the first transfer mechanism 320 are performed simultaneously, which is beneficial to improving the work efficiency.

As shown in fig. 5 to 6, specifically, the transfer platform 330 includes a first mounting frame 331 and a plurality of first loading frames 332. The first mounting frame 331 is disposed on the first frame 100, and the plurality of first loading frames 332 are disposed in parallel and at intervals so as to be convenient for loading the plurality of transverse bus bars 1000, so that the first transfer mechanism 320 can transfer the transverse bus bars, thereby reducing the waiting time of the transverse preparation mechanism 310 or the conveying device 200. Illustratively, after the lateral preparation mechanism 310 prepares one lateral bus bar 1000, the first transfer mechanism 320 places it on the transfer platform 330, and then may proceed to prepare the next. At this time, the first transfer mechanism 320 may sequentially transfer the lateral bus bars 1000.

As shown in fig. 5 to 6, the first bearing frame 332 further includes a first bearing main body 3321 and a plurality of first position-limiting members 3322. The first bearing main body 3321 is disposed on the first mounting block 331, the plurality of first limiting members 3322 are divided into a plurality of groups, each group of first limiting members 3322 includes two, two first limiting members 3322 are disposed on the first bearing main body 3321 at intervals, the plurality of groups of first limiting members 3322 are disposed in parallel and at intervals, and the transverse bus bar 1000 can pass through the interval of each group of first limiting members 3322, so that the transverse bus bar 1000 is prevented from falling off from the first bearing frame 332, and stability and safety of a transfer process are improved. Illustratively, the bus bar is a copper strip, the copper strip is a flat strip-shaped structure, and the prepared transverse bus bar 1000 may be flatly placed between the two first retaining members 3322, and the two side positions thereof are restrained by the two first retaining members 3322 so as to extend along the X direction.

As shown in fig. 6, in order to improve the stability of fixing the transverse bus bar 1000, the first frame 332 is provided with a plurality of first absorption holes 3323, the plurality of first absorption holes 3323 are disposed along the extending direction of the first frame 332, and the first absorption holes 3323 can be communicated with the vacuum generating device, so as to absorb the transverse bus bar 1000, increase the stability of fixing the transverse bus bar 1000, and avoid falling.

Of course, the lateral preparing apparatus 300 further includes a discharging mechanism (not shown) for discharging the loaded lateral bus bar 1000 to the lateral preparing mechanism 310. In order to reduce the occupied space, the discharging mechanism of the lateral preparation device 300 may be disposed outside the bus bar welding apparatus, which is advantageous to save space. In order to further improve the stability of the lateral preparation apparatus 300, two discharging mechanisms may be provided for each lateral preparation mechanism 310, one discharging mechanism is disposed below the left side, and the other discharging mechanism is disposed on the right side, so as to save the occupied space of the discharging mechanisms. And when one emptying mechanism breaks down, the other emptying mechanism can ensure that the equipment runs smoothly. Illustratively, the driving piece of the discharging mechanism is preferably a stepping motor driving piece, and the stepping motor driving piece has better accuracy and is beneficial to improving the accuracy of the discharging size.

Because the bus bar is a long strip-shaped copper strip, the bus bar is easy to thin or break under the stretching of a preparation mechanism. In this embodiment, the lateral preparing apparatus 300 further includes a buffer mechanism 340, and the buffer mechanism 340 is disposed between the material placing mechanism and the preparation of the lateral bus bar 1000, and is used for buffering the bus bar with a preset length. The detailed structure of the buffer mechanism 340 will now be described with reference to fig. 7.

As shown in fig. 7, the buffer mechanism 340 includes a fourth frame 341, a first fixed wheel 343, and two movable wheels 342 disposed at an interval. The two driving wheels 342 can move along the Z direction (third direction), the moving directions of the two driving wheels 342 are the same, the first fixed wheel 343 is disposed between the two driving wheels 342, and the transverse bus bar 1000 bypasses one driving wheel 342, the first fixed wheel 343 and the other driving wheel 342 at a time. The buffer mechanism 340 buffers the transverse bus bar 1000 by using four distances, namely, the distance between the two driving wheels 342 and the first fixed wheel 343, the distance between the input end of the transverse bus bar 1000 of the buffer mechanism 340 and the first driving wheel 342, and the distance between the second driving wheel 342 and the output end of the transverse bus bar 1000 of the buffer mechanism 340, so that the speed difference between the input speed and the output speed of the transverse bus bar 1000 at the two ends of the buffer mechanism 340 is adjusted, and the transverse bus bar 1000 is prevented from being thinned or broken due to over-tension of the output end. Meanwhile, the buffer mechanism 340 has four distances for buffering the transverse bus bars 1000, and the buffer length is increased under the condition of the same size, so that the occupied space of the buffer mechanism 340 is saved, and the application range is expanded. The buffer mechanism 340 also has the function of straightening the transverse bus bar 1000.

With reference to fig. 7, further, the buffer mechanism 340 further includes a first guiding assembly 344 disposed between the driving wheel 342 and the fourth frame 341, and the first guiding assembly 344 can provide a guide for the driving wheel 342 to move along the third direction, so as to improve the stability of the driving wheel 342 moving along the Z direction and prevent the transverse bus bar 1000 from being deformed or broken due to the shaking of the driving wheel 342 during the movement process.

With reference to fig. 7, in detail, the first guiding assembly 344 includes a first guiding rail 3441 and a first sliding block 3442, the first guiding rail 3441 is disposed on the fourth frame 341 along the Z direction, the first sliding block 3442 is slidably connected to the first guiding rail 3441, two driving wheels 342 are disposed on the first sliding block 3442, and the two driving wheels 342 can rotate relative to the first sliding block 3442. At this time, the two driving wheels 342 are both disposed on the first slider 3442, so that the two driving wheels 342 can move along the Z direction at the same time, and the linkage acting force of the transverse bus bar 1000 between the two driving wheels 342 is reduced, which is beneficial to further ensuring the quality of the transverse bus bar 1000 and avoiding damage.

In other embodiments, the first guide assembly 344 includes two first guide rails 3441 and two first sliders 3442. The two first guide rails 3441 are disposed in parallel and spaced, the first guide rails 3441 are disposed on the fourth frame body 341 along the Z direction, the two first sliding blocks 3442 are slidably connected to the two first guide rails 3441, the two driving wheels 342 and the two first sliding blocks 3442 are disposed in a one-to-one correspondence manner, the driving wheels 342 are rotatably disposed on the first sliding blocks 3442, and the first guiding assembly 344 is simple in structure and convenient for an operator to assemble and maintain. And the two driving wheels 342 can move upwards or downwards along the Z direction independently, so that the effect of releasing the cache is achieved.

As an alternative, as shown in fig. 7, the initial position of the movable wheels 342 is located at the middle of the range of motion of the movable wheels 342 in the Z direction, so that both the movable wheels 342 have a space to move up or down in the Z direction. Of course, in other embodiments, the initial position of the traction wheel 342 may be at the lowermost end.

When the bus bar stretching speed downstream of the buffer mechanism 340 (i.e. the transverse preparation mechanism 310) is greater than the bus bar releasing speed upstream of the buffer mechanism 340 (i.e. the drop mechanism), the two fixed wheels can move upwards along the Z direction at the same time to release the bus bars on the buffer mechanism 340, so that the bus bar length required by the bus bar preparation mechanism stretching can be sufficiently supplied, and the transverse bus bar 1000 damage caused by too large speed difference can be avoided.

Of course, when the bus bar stretching speed downstream of the buffer mechanism 340 (i.e. the transverse preparation mechanism 310) is greater than the bus bar releasing speed upstream of the buffer mechanism 340 (i.e. the drop mechanism), the two fixed wheels can simultaneously move in the negative direction of the third direction to release the bus bars on the buffer mechanism 340. That is, the buffer mechanism 340 can adjust the buffer length by adjusting the position of the fixed wheel in the Z direction, so that the length released by the material discharging mechanism can be absorbed, and the effect of ensuring the stable operation of the transverse preparation device 300 is achieved.

As shown in fig. 7, as an alternative, the buffer mechanism 340 further includes a second fixed wheel 345 disposed on the fourth frame body 341, and the first fixed wheel 343 is rotatably connected with the fourth frame body 341, and the bus bars are led from the second fixed wheel 345 to the driving wheels 342, thereby improving the stability of leading the transverse bus bars 1000 to the driving wheels 342. Meanwhile, the second fixed wheel 345 also has an effect of redirecting the drawing direction.

With continued reference to fig. 7, it can be understood that the buffer mechanism 340 further includes a third fixed wheel 346 disposed on the fourth frame 341, and the third fixed wheel 346 is rotatably connected to the fourth frame 341, and the bus bar passes through the two movable wheels 342 and then is led out from the second fixed wheel 345, so as to improve the stability of the output of the transverse bus bar 1000 from the movable wheels 342. Meanwhile, the third fixed wheel 346 also has the effect of redirecting the output direction.
