[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-10 , the embodiment of the present invention includes:

[0029] A high-speed string welding machine welding conveying line consists of two lines A and B. The structures of production line A and production line B are symmetrical. The two lines weld synchronously, and the production efficiency is doubled. The structure consists of a welding platform and a paddle-type conveying device.

[0030] An infrared temperature sensor 20 is arranged below the welding platform to monitor the temperature of the back side of the battery cell.

[0031] A welding ribbon guide plate 19, a battery cell adsorption plate 12, a high-temperature welding platform 16 and a rear plate 22 are arranged on the welding platform. The welding ribbon guide plate 19, the battery cell adsorption plate 12, the high-temperature welding platform 16 and the rear plate 22 are all provided with a guide groove for accommodating the lower welding ribbon 601b to ensure that the lower welding ribbon 601b does not deviate during the welding process. The guide groove is a groove-shaped structure.

[0032] The soldering ribbon 600 is clamped by the clamping claws and enters the battery cell adsorption plate 12 from the soldering ribbon guide plate 19. Both the soldering ribbon guide plate 19 and the battery cell adsorption plate 12 are provided with guide grooves for accommodating the soldering ribbon 600. Except for the clamping length of the head, the rear half 601b of the soldering ribbon is always kept in the guide groove. The battery cell is placed on the battery cell adsorption plate 12 by the robotic arm. The battery cell adsorption plate 12 is connected with a vacuum to adsorb and fix the battery cell. After placing another soldering ribbon 600 on the upper surface of the battery cell, the robotic claws place the soldering ribbon pressing block 66 on the upper soldering ribbon and the battery cell. The pressing block pressing needle 101 on the soldering ribbon pressing block 66 presses down the upper soldering ribbon 601a to make it close to the battery cell.

[0033] The welding strip below the battery cell is the front welding strip 601a, and the welding strip above the battery cell is the rear welding strip 601b.

[0034] The rear half 601b of the front solder strip is placed in the guide groove of the battery cell adsorption plate 12, the battery cell is placed above the battery cell adsorption plate 12, the front half 601a of the rear solder strip is placed on the battery cell, and the solder strip pressing block 66 is placed on the solder strip and the battery cell. A pressing pin 101 and a magnet 102 are provided on the solder strip pressing block 66. The pressing pin 101 presses the upper solder strip. When the solder strip pressing block 66 is placed on the conveying line, the magnet 102 is adsorbed and fixed at the gap position between the inner adsorption plate 13 and the outer adsorption plate 14.

[0035] The paddle-type transport device includes a transport paddle 21 and a paddle-type transport mechanism 11. The paddle-type transport mechanism 11 includes a transport guide rail 111, a paddle mechanism 112, a translation screw servo mechanism 113 and a lifting screw servo mechanism 114. When the translation motor is activated, the transport mechanism is driven to translate one or two battery cell spacings.

[0036] Adjacent transport paddles 21 are connected by a contraction joint mechanism 211 , and the contraction joint mechanism 211 includes a floating connection piece 2111 , a connection bottom piece 2112 and equal height screws 2113 .

[0037] The paddle mechanism includes a lifting guide rail 1121, a push guide rail 1122, a slider fixing plate 1123, a rocker rod 1124, a connecting plate 1125, a push plate 1126 and a lifting plate 1127. The lifting screw servo mechanism 114 is connected to the slider fixing plate 1123. When the lifting motor is activated, the push plate 1126 moves horizontally along the push guide rail 1122, and the lifting plate 1127 is driven to move up and down along the lifting guide rail 1121 through the rocker rod 1124.

[0038] When the lifting motor is activated, the lifting plate 1127 and the transport paddle 21 fixed thereto are lifted together, the battery cell and the solder strip pressing block 66 placed on the battery cell adsorption plate 12 rise, and the magnet 102 detaches from the inner adsorption plate 13 and the outer adsorption plate 14 and is instead adsorbed on the transport paddle 21.

[0039] After the battery cell is lifted to a certain height, the translation motor starts to operate, and the transport paddle 21 and all the battery cells and the solder ribbon pressing block 66 thereon move forward together, and move along the transport guide rail 111 by one or two battery cell spacings; after reaching the position, the transport paddle 21 descends, and the battery cell is placed on the battery cell adsorption plate 12 again, and the solder ribbon pressing block 66 is adsorbed and fixed on the inner adsorption plate 13 and the outer adsorption plate 14 again, and the transport paddle 21 is separated from the magnet 102.

[0040] Preferably, the magnets 102 are respectively disposed at both ends of the welding strip pressing block 66 , and are located between the gap between the inner adsorption plate and the outer adsorption plate.

[0041] After the transport paddle 21 reaches the lowermost position, the translation motor moves in the reverse direction, and the transport paddle 21 returns to the original position, and the battery cell and the soldering ribbon pressing block 66 remain on the battery cell adsorption plate 12 or 16 high-temperature soldering table.

[0042] A pressing needle lifting mechanism 15 is arranged below the high temperature welding platform 16. After the battery cell and the soldering strip pressing block 66 reach the set position of the high temperature welding platform 16, the pressing needle lifting mechanism 15 is actuated to push the lower pressing needle 191 to push the lower soldering strip 601b upwards to ensure that the lower soldering strip 601b fits the battery cell. The soldering strip pressing block 66 above the battery cell presses the upper soldering strip 601a downwards to make it fit the battery, and then the upper infrared lamp heats and welds it.

[0043] A preheating plate 18 is provided at the bottom of the battery cell adsorption plate 12 , and a high-temperature heating plate 17 is provided at the bottom of the high-temperature welding station 16 . The battery cell and the welding ribbon pressing block 66 are gradually heated during the process of moving from the battery cell adsorption plate 12 to the high-temperature welding station 16 .

[0044] The welded battery cells and the solder ribbon pressing blocks 66 are transported to the rear placement plate 22, and the solder ribbon pressing blocks 66 are taken away by a robot for reflow, and the battery cells welded into a string are then processed by subsequent processes.

[0045] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
