DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0027] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] like Figures 1 to 6 As shown, the present application discloses a battery string carrying platform, which includes a base 100, a first reference member 210, a second reference member 220 and a telescopic table mechanism 300, wherein the base 100 can provide an installation foundation for the first reference member 210, the second reference member 220 and the telescopic table mechanism 300, and the first reference member 210, the second reference member 220 and the telescopic table mechanism 300 can form a bearing surface, and the bearing surface is used to carry the battery string.

[0030] Specifically, the first reference member 210 and the second reference member 220 are spaced apart on the base 100. No matter how long the battery string is, the two battery strings are spaced apart along the length direction of the string during layout, and then the two battery strings are arranged in sequence along the width direction of the string, and the spacing between the two battery strings is basically fixed. Therefore, the spacing between the first reference member 210 and the second reference member 220 can be the same as the above spacing, thereby ensuring the layout accuracy of the battery string. At the same time, there are two telescopic table mechanisms 300, and the two telescopic table mechanisms 300 are movably arranged on the base 100. The first reference member 210 and the second reference member 220 are located between the two telescopic table mechanisms 300.

[0031] During the use of the battery string carrying platform, if it is necessary to replace battery strings of different string lengths and specifications, the two telescopic platform mechanisms 300 can be moved relative to the base 100, and one of the two telescopic platform mechanisms 300 adjacent to the first reference member 210 can be moved relative to the first reference member 210 to get closer to or away from the first reference member 210. Of course, the other of the two telescopic platform mechanisms 300 adjacent to the second reference member 220 can be moved relative to the second reference member 220 to get closer to or away from the second reference member 220, ensuring that the welding strip of the battery string is exposed outside the battery string carrying platform, so that the battery string carrying platform can be compatible with the layout of battery strings of different string lengths and specifications, avoiding the need to replace the battery string carrying platform, which is beneficial to reducing the cost of manual replacement and maintenance.

[0032] Compared with manually adjusting the two telescopic table mechanisms 300, in the embodiment of the present application, any one of the two telescopic table mechanisms 300 may include a driving assembly 310 and a support plate 320. Specifically, the driving assembly 310 is disposed on the base 100, and the support plates 320 are both slidably connected to the base 100. The driving assembly 310 is connected to the support plates 320, and the support plates 320 can be driven to move by the driving assembly 310. Compared with manual adjustment, the driving assembly 310 can improve the movement accuracy of the support plates 320, and is also convenient for simultaneous adjustment, so that the support plates 320 adjacent to the first reference member 210 can approach or move away from the first reference member 210, and the support plates 320 adjacent to the first reference member 210 can approach or move away from the first reference member 210.

[0033] In an optional solution, the support plate 320 may be multiple, and the driving assembly 310 may include a first driving member 311 and a scissor-type telescopic assembly 312. Specifically, the scissor-type telescopic assembly 312 includes multiple articulated shafts and multiple articulated parallelograms. The multiple articulated parallelograms are sequentially articulated in series through multiple articulated shafts. The multiple support plates 320, the first reference member 210 or the second reference member 220 are connected to the multiple articulated shafts in a one-to-one correspondence. Any one of the multiple support plates 320 is connected to the first driving member 311. When any one of the multiple support plates 320 is driven to move, the hinge shaft connected to the support plate 320 will move accordingly, while the hinge shaft connected to the first reference member 210 or the second reference member 220 will be fixed. Since the multiple articulated parallelepiped rods are sequentially hinged and connected in series through the multiple articulated shafts, the multiple articulated parallelepiped rods will rotate and fold relative to each other to make the remaining articulated shafts approach or move away from each other by the same distance in one direction, so that the multiple support plates 320 can approach or move away from the first reference member 210 or the second reference member 220 synchronously and equidistantly.

[0034] The above structure not only increases the number of support plates 320 to be compatible with the layout of battery strings with larger string length specifications, but also does not require high installation accuracy for the connection and coordination between the scissor-type telescopic assembly 312 and the multiple support plates 320, thereby facilitating installation and maintenance.

[0035] In another optional scheme, there can be multiple support plates 320, and the driving assembly 310 can include a first driving member 311 and a meshing telescopic arm group 313. Specifically, the meshing telescopic arm group 313 includes multiple telescopic arms, and the multiple telescopic arms are all provided with synchronous belts. The multiple telescopic arms are sequentially sleeved, and the multiple telescopic arms are sequentially meshed and connected in series through multiple synchronous belts. The multiple support plates 320 are connected to the multiple telescopic arms one by one, and one of the multiple telescopic arms is connected to the first driving member 311.

[0036] Among them, the above-mentioned structure adopts a synchronous belt. Since the synchronous belt is a gear and a belt meshing together, the transmission accuracy is high. Multiple telescopic arms are meshed in series in sequence through multiple synchronous belts, so that the multiple telescopic arms are meshed and matched with the belts of multiple synchronous belts in sequence. When the first driving member 311 drives one of the multiple telescopic arms to move, the synchronous belt of one of the multiple telescopic arms will also rotate accordingly. The synchronous belt can drive the telescopic arm meshing with it to move, and so on. The remaining multiple telescopic arms will all move, thereby facilitating the control of the moving distance of the multiple support plates 320, thereby better ensuring the adaptability to battery strings with different string length specifications.

[0037] In an embodiment of the present application, the disclosed battery string supporting platform may further include a pneumatic control component. Specifically, the support plate 320, the first reference member 210 and the second reference member 220 are all provided with connected air holes and adsorption holes. The adsorption holes are provided at the supporting ends of the support plate 320, the first reference member 210 and the second reference member 220. Multiple pipelines of the pneumatic control component are connected to the air holes of the support plate 320, the first reference member 210 and the second reference member 220 in a one-to-one correspondence. When the supporting surface formed by the support plate 320, the first reference member 210 and the second reference member 220 carries the battery string, the pneumatic control component controls the multiple passages formed by the multiple pipelines and the multiple air holes to be negative pressure, so that the multiple adsorption holes can exert adsorption force on the battery string, thereby avoiding deflection or misalignment of the battery string after typesetting.

[0038] In the embodiment of the present application, the first reference member 210 and the second reference member 220 are movably arranged on the base 100, so as to facilitate the first reference member 210 and the second reference member 220 to flexibly adjust the spacing. The first reference member 210 and the second reference member 220 are both provided with self-locking members that cooperate with their threads. The self-locking members can cooperate with the base 100 in a limited position, so as to facilitate the relative fixation of the first reference member 210 and the second reference member 220 relative to the base 100 after the spacing is flexibly adjusted.

[0039] In the embodiment of the present application, the first reference member 210, the second reference member 220 and the support plate 320 can all be provided with an avoidance groove A. In order to avoid the battery string carrying platform from being too large and interfering with other components, only a portion of the battery strings required for the photovoltaic modules can be arranged. In order to integrate the number of battery strings required for the photovoltaic modules, it may be necessary to move the arranged battery strings multiple times. During the transportation process, in addition to grabbing a portion of the arranged battery strings, it is also necessary to grab multiple arranged battery strings placed on the battery string carrying platform. The avoidance groove A can prevent the grabbed portion of the arranged battery strings from contacting the battery string carrying platform, thereby preventing the battery cells constituting the battery string from colliding and being damaged.

[0040] like Figure 7 As shown, the present application also discloses a welding device, which includes a battery string gripper 400, a welding head 500, a string lifting mechanism and the above-mentioned battery string carrying platform. Specifically, the gripper can grab the battery string and arrange it on the battery string carrying platform. There are two welding heads 500, and the two welding heads 500 are respectively arranged on both sides of the battery string carrying platform, so that the busbars can be welded to the multiple battery strings that have been arranged. The string lifting mechanism is used to grab the multiple battery strings that have been arranged, so as to facilitate the busbar welding of the next process.

[0041] In the embodiment of the present application, the disclosed welding equipment may further include a second driving member 600. Specifically, there are two second driving members 600, which are arranged on both sides of the battery string carrying platform. The two second driving members 600 are connected to the two welding heads 500 in a one-to-one correspondence. The two driving members can drive the two welding heads 500 to approach or move away from the battery string carrying platform in a one-to-one correspondence, so that the two welding heads 500 can be compatible with the busbar welding of battery strings with different string length specifications. The above structure can avoid manual adjustment of the two welding heads 500, and is also conducive to the automated design of the movement of the welding heads 500.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
