[0027] The clamping mechanism 4 comprises a placing table 401, a limiting frame 402 and a sliding block 403, the placing table 401 is fixed on the first linear motor 3, the limiting frame 402 is symmetrically arranged on the upper end face of the placing table 401, the lower end of the limiting frame 402 is fixed with the sliding block 403, the sliding block 403 is in sliding connection with the placing table 401, and the limiting frame 402 is locked with the placing table 401 through bolts; the pay-off mechanism 12 comprises a rotating shaft 1201, a wire coil 1202, a locking nut 1203, a tin wire 1204, a first motor 1205, a feeding wheel 1206 and a gear 1207, the rotating shaft 1201 is bearing connected on the movable table 1106, the wire coil 1202 is nested on the rotating shaft 1201, and the wire coil 1202 is locked with the rotating shaft 1201 through the locking nut 1203; the tin wire 1204 is connected on the wire coil 1202, and the tin wire 1204 is in sliding connection with the lead pipe 1108; the first motor 1205 is fixed on the movable table 1106, the output end of the first motor 1205 is fixed with the feeding wheel 1206, the feeding wheel 1206 is bearing connected on the movable table 1106, the surface of the feeding wheel 1206 is rough structure, the feeding wheel 1206 is in contact with the tin wire 1204; the feeding wheel 1206 is further fixed with the gear 1207, and the two gears 1207 are in meshing connection;

[0028] When the lithium battery protection plate tin soldering device is used, as Figures 1-7As shown, first, the lithium battery protection plate to be processed is placed on the placement table 401, and the sliding guide action between the sliding block 403 and the placement table 401 can adjust the position of the limiting frame 402, until the limiting frame 402 contacts the lithium battery protection plate, and the limiting action of the lithium battery protection plate can be realized, and finally the limiting frame 402 and the placement table 401 are locked by bolts, and when processing, the front and rear positions of the lithium battery protection plate can be adjusted by the first linear motor 3, and the left and right positions of the soldering head 10 can be adjusted by cooperating with the second linear motor 6, and the up and down positions of the soldering head 10 can be adjusted by cooperating with the cylinder 8, so as to ensure the normal progress of the soldering process. After the lithium battery protection plate is fixed, when processing, the soldering head 10 is moved to the position above the lithium battery protection plate by the action of the first linear motor 3 and the second linear motor 6, and then the cylinder 8 is controlled to extend, thereby driving the mounting plate 9, the soldering head 10 and the adjusting mechanism 11 to move downward. When the vertical rod 1103 contacts the lithium battery protection plate, the vertical rod 1103 and the movable ring 1101 are forced to move upward relative to the mounting plate 9, and the spring 1104 is forced to contract, until the movable ring 1101 contacts the limiting plate 1102 to realize positioning. Since the distance between the lower end surface of the vertical rod 1103 and the lower end surface of the soldering head 10 is 1mm-2mm larger than the distance between the movable ring 1101 and the limiting plate 1102, the distance between the soldering head 10 and the processing position of the lithium battery protection plate is 1mm-2mm at this time, which ensures the normal progress of soldering. When the movable ring 1101 slides upward, the movable table 1106 and the pay-off mechanism 12 move to the right under the transmission action of the connecting rod 1105, and the sliding guide action between the cross rod 1107 and the vertical plate 901 can ensure the stability of the movement of the movable table 1106 and the pay-off mechanism 12. When the movable ring 1101 contacts the limiting plate 1102 to realize positioning, the end of the solder wire 1204 contacts the soldering head 10 at this time, so as to facilitate subsequent soldering. When welding, the first motor 1205 drives the feed wheel 1206 to rotate, and the synchronous rotation of the two feed wheels 1206 is realized under the meshing transmission action between the two gears 1207, and the automatic feeding action of the solder wire 1204 can be realized under the rough structure on the surface of the feed wheel 1206, which ensures the normal progress of the soldering process. Moreover, according to the above principle, when the soldering is completed, the vertical rod 1103 is separated from the lithium battery protection plate under the action of the cylinder 8, at this time, the movable table 1106 and the pay-off mechanism 12 are reset under the action of the spring 1104, so that the end of the solder wire 1204 is separated from the soldering head 10, realizing the avoiding action, avoiding that too much solder is adhered to the soldering head 10 to affect the quality of subsequent soldering;

[0029] The soot blowing mechanism 13 includes a fixed cylinder 1301, a one-way inlet valve 1302, a one-way outlet valve 1303, a nozzle 1304, a fixed rod 1305, a piston 1306, and a connecting frame 1307. The fixed cylinder 1301 is fixed on the mounting plate 9, and the one-way inlet valve 1302 is installed on the upper end face of the fixed cylinder 1301. The one-way outlet valve 1303 is installed on the left side of the fixed cylinder 1301. The one-way outlet valve 1303 is connected to the nozzle 1304 through a conduit. The nozzle 1304 is installed at an angle on the side of the solder head 10, and the lower end face of the nozzle 1304 is higher than the lower end face of the solder head 10. The nozzle 1304 is fixed to the mounting plate 9 by the fixing rod 1305. A piston 1306 is slidably connected inside the fixing cylinder 1301, and the piston 1306 is slidably connected to the mounting plate 9. A connecting frame 1307 is fixed to the lower end of the piston 1306, and the connecting frame 1307 is connected to the vertical rod 1103.

[0030] During the processing, such as Figures 1-7 As shown, when the vertical rod 1103 moves upward relative to the mounting plate 9, it synchronously drives the connecting frame 1307 to move upward, thereby driving the piston 1306 to slide upward in the fixed cylinder 1301. With the action of the one-way air inlet valve 1302 and the one-way air outlet valve 1303, the gas in the fixed cylinder 1301 enters the nozzle 1304 through the one-way air outlet valve 1303 and the conduit and is ejected. The high-speed airflow ejected by the nozzle 1304 can perform soot blowing treatment on the soldering position of the lithium battery protection board before the solder head 10 reaches the predetermined position, ensuring the surface of the lithium battery protection board is clean, thereby ensuring the soldering quality. Moreover, since the soot blowing treatment is performed before the solder head 10 reaches the predetermined position, it can effectively avoid the airflow affecting the solder during soldering, ensuring the normal progress of the soldering process. This is the working principle of the lithium battery protection board soldering device.
