The present invention realizes the automatic sequential arrangement of battery sheets through the battery arranging module, and realizes the addition and welding of welding tapes through the battery welding module, and can realize the full automation of solar cell string welding.

[0005] In this regard, Chinese Patent Application No.: CN110767847B discloses a battery welding protection assembly, which is used to protect each component on the top cover, including two pole columns or a liquid injection hole, etc., during the welding process of the battery housing and the top cover. The assembly includes: a base cover, which includes two end faces and two side faces. The direction of the line connecting the two end faces is along the direction of the line connecting the two pole columns, and the direction of the line connecting the two side faces is perpendicular to the direction of the line connecting the two pole columns. The base cover is placed between the two pole columns; a plurality of protection sheets, which are elastically connected to the side faces; the protection sheet includes a protection arm extending out of the base cover for covering the surface of the pole column; the two protection arms and the end face enclose the pole column and separate the pole column from the weld seam; when viewed directly from above the top cover of the battery, the outer contour of the battery welding protection assembly is contained within the weld seam. This battery welding protection assembly can simply and conveniently provide effective protection for the pole column during the welding process.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0035] Combined with Figures 1 - 10, New energy vehicle battery pack battery series connection piece automatic assembly machine, including assembly equipment 1. The assembly equipment 1 includes an installation frame body 110. A positioning base 120 is fixedly connected to the bottom end of the installation frame body 110. A metal series connection piece 130 is embedded and connected inside the installation frame body 110. When assembling new energy batteries, the series connection pieces are connected in series to the positive and negative electrodes of the batteries by soldering. By corresponding the positive electrode to the negative electrode in sequence, the series connection of the batteries can be completed. Among them, first, the batteries during processing are limited in position to a certain extent through the installation frame body 110 and the positioning base 120; A cutting assembly 2 is fixedly connected to the upper end of the installation frame body 110. The cutting assembly 2 includes a fixed frame 220. The fixed frame 220 is fixedly connected to the upper end of the installation frame body 110. A driving motor 1 210 is fixedly connected to the upper end of the fixed frame 220. The output end of the driving motor 1 210 is fixedly connected to a plug rod 250. The upper end of the plug rod 250 is fixedly connected to a cutting roller knife 230. The cutting roller knife 230 is horizontally arranged at the top of the metal series connection piece 130. The metal series connection piece 130 is continuously pushed forward by an external conveying device. Among them, the metal series connection piece 130 can drive the rollers through a motor, and utilize the friction force between the rollers and the metal series connection piece 130 to continuously push the metal series connection piece 130 forward. When the metal series connection piece 130 is pushed to the bottom of the cutting roller knife 230 and located at the top of two battery bodies 440, the driving motor 1 210 starts to work, driving the rotation of the plug rod 250. When the plug rod 250 rotates, it drives the cutting roller knife 230 to start rotating. Then, when the blade connected to the upper end of the cutting roller knife 230 touches the metal series connection piece 130, the metal series connection piece 130 is cut, and the cutting causes the metal series connection piece 130 to break. Among them, due to the different rotation speeds of the driving motor 1 210, the cutting length of the metal series connection piece 130 is also different. When the input distance of the metal series connection piece 130 is certain at the same moment, if the rotation speed of the cutting roller knife 230 is fast, the cutting length of the metal series connection piece 130 is reduced; conversely, if the rotation speed is slow, the cutting length is increased.

[0036] There are two sets of metal series-connected sheets 130. One set of metal series-connected sheets 130 is embedded in the bottom end of the positioning cover plate 240, and the other set of metal series-connected sheets 130 passes through the mounting frame 110 and is embedded inside the lifting assembly 4. The position of the metal series-connected sheets 130 can be positioned through the positioning cover plate 240. At the same time, the semi-circular new groove opened at the upper end of the positioning cover plate 240 cooperates with the clamping plate 410 to further limit the position of the battery body 440. The battery body 440 placed inside the clamping plate 410 and the positioning cover plate 240 is position-limited by the positioning cover plate 240 and the clamping plate 410. The limited battery body 440 is also simpler and more convenient in subsequent processing, which also improves work efficiency. The top end of the positioning base 120 is fixedly connected with a lifting assembly 4. The lifting assembly 4 includes an electric push rod 420. The top end of the positioning base 120 is fixedly connected with an electric push rod 420. The upper end of the mounting frame 110 is fixedly connected with a clamping plate 410. The top end of the electric push rod 420 is fixedly connected with a tray 430. A gasket 450 is embedded inside the tray 430. An inlet groove 460 is opened inside the tray 430. One set of metal series-connected sheets 130 is embedded inside the inlet groove 460. The battery body 440 is embedded and connected inside the positioning cover plate 240 and the clamping plate 410. The bottom end of the battery body 440 is connected with a gasket 450. Semi-circular grooves are opened at the upper ends of the clamping plate 410 and the positioning cover plate 240. There are two sets of clamping plates 410. The two sets of clamping plates 410 are respectively located above and on both sides of the positioning cover plate 240. When the battery body 440 is placed on the upper end of the tray 430, the bottom end of the battery body 440 is supported by the tray 430. At the same time, the height of the tray 430 is adjusted by the rising and falling of the electric push rod 420. After the two battery bodies 440 are fixed by the integrating assembly 5, the position of the battery body 440 is fixed again by the positioning cover plate 240 and the clamping plate 410. The two fixings strengthen the stability of the battery body 440 and can also avoid deviation during the connection of the battery series-connected sheets. Among them, the electric push rod 420 drives the rising and falling of the tray 430 and further controls the height of the battery body 440.

[0037] The bottom end of the pallet 410 is fixedly connected with an integration component 5. The integration component 5 includes a baffle 510. The upper end of the mounting frame body 110 is fixedly connected with a limiting strip 520. The limiting strip 520 is arranged in an L shape. An electric push rod II 530 is installed inside the limiting strip 520. The upper end of the limiting strip 520 is connected with a first clamping strip 540. The upper end of the baffle 510 is connected with a second clamping strip 550. The second clamping strip 550 and the first clamping strip 540 wrap around the upper end of the battery body 440. The second clamping strip 550 is embedded inside the first clamping strip 540. When the battery body 440 drops onto the upper end of the tray 430, its upper end is fixed by the pallet 410 and the electric push rod I 420, and the bottom end is fixed by the tray 430. Then the middle part is fixed by being embedded inside the first clamping strip 540 and the second clamping strip 550. Through the connection of the first clamping strip 540 and the second clamping strip 550, two battery bodies 440 can be connected together. The specific operation is as follows. When the battery body 440 drops onto the tray 430, the electric push rod II 530 is pushed forward. After being pushed forward, it strikes the first clamping strip 540, causing the second clamping strip 550 to be embedded into the groove inside the first clamping strip 540, completing the connection between the two groups. After the limiting strip 520 moves outwards, the magnet at the upper end of the limiting strip 520 will adsorb the first clamping strip 540 and pull it towards the side close to the moving direction of the limiting strip 520, causing the second clamping strip 550 to separate from the baffle 510. Then, under the gravity of the second clamping strip 550 and the battery body 440, it disengages from the limiting strip 520. The distance between the first clamping strip 540 and the second clamping strip 550 is reduced, and its two ends cannot be placed on the upper ends of the baffle 510 and the limiting strip 520 either. Then the downward movement of the electric push rod I 420 drives the downward movement of the electric push rod II 530. After the downward movement, when the top end of the battery body 440 disengages from the pallet 410 and the positioning cover plate 240, the battery body 440 is pushed to the upper end of the output component 3 through pushing the push rod 370 for transfer out. The metal series connection piece 130 embedded inside the guiding groove 460 is completed through the tin soldering device and the cutting device externally connected to the bottom end.

[0038] The upper end of the mounting frame body 110 is fixedly connected with a pressing component 6. The pressing component 6 includes a driving motor II 610. The output end of the driving motor II 610 is fixedly connected with a gear 630. The bottom end of the positioning cover plate 240 is fixedly connected with a rack bar 620. By the rotation of the driving motor II 610, the rotation of the rack bar 620 is driven, and further the gear 630 can move up and down, further controlling the up and down movement of the positioning cover plate 240. When the positioning cover plate 240 descends, it presses on the upper end of the metal series connection piece 130 more firmly.

[0039] An output component 3 is fixedly connected to the inner side of the mounting frame 110. The output component 3 includes a positioning strip 320. The positioning strip 320 is fixedly connected to the inner side of the mounting frame 110. A column 310 is connected to the inner side of the positioning strip 320. A positioning column 340 is fixedly connected to the top end of the positioning base 120. The top end of the positioning column 340 is connected to an output plate 330. The end of the output plate 330 is connected to a movable shaft 360. The upper end of the movable shaft 360 is connected to a connecting rod 350. A push rod 370 is connected through the interior of the mounting frame 110. Two sets of columns 310 and positioning strips 320 are provided. The two sets of columns 310 and positioning strips 320 are respectively located on both sides of the battery body 440. The output plate 330 is connected to the tray 430 through the connecting rod 350 and the movable shaft 360. The movable shaft 360 is respectively connected to both sides of the connecting rod 350. One side of the connecting rod 350 is connected to the output plate 330 through the movable shaft 360. The other side of the connecting rod 350 is connected to the tray 430 through the movable shaft 360. By pushing with the push rod 370, the battery body 440 is pushed to the upper end of the output plate 330, and then the position of the battery body 440 is restricted by the positioning strip 320 and the column 310, so that the battery body 440 can be conveyed out orderly.
