[0015] Compared with the prior art, this utility model provides a soldering device for the acquisition line of a battery cell module, which has the following beneficial effects:

[0016] (1) This utility model adopts a mounting shell and an unwinding assembly on the support frame. By placing the welding wire roll on the central column of the mounting shell, the solder wire on the welding wire roll extends out from the wire outlet and extends between the upper guide wheel and the lower guide wheel inside the unwinding assembly. As the hand crank drives the upper guide wheel to rotate, the lower guide wheel rotates with the upper guide wheel, realizing the unwinding of the welding wire roll until the solder wire extends out from the end of the guide tube. Combined with the use of the electric arc iron, it is easy to perform soldering operations on the battery cell module acquisition line.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a soldering device for a battery cell module acquisition line according to an embodiment of the present invention includes a support frame 1. A mounting shell 2 is fixed to the top surface of the support frame 1, and a central column 3 is welded inside the mounting shell 2. A wire coil 4 is sleeved on the surface of the central column 3. An unwinding assembly 5 is installed on the left side of the top surface of the support frame 1, and a height adjustment frame 6 is installed at the left edge of the support frame 1. An upper guide wheel 10 and a lower guide wheel 11 are rotatably mounted inside the unwinding assembly 5 from top to bottom. A connecting sleeve 13 is fixed at the axle of the upper guide wheel 10. A hand crank 14 is inserted and fixed into the square notch of the connecting sleeve 13. A wire guide 7 is attached to one end of the unwinding assembly 5 facing the height adjustment frame 6, and one end of the wire guide 7 extends to the inside of the height adjustment frame 6. The solder wire on the solder wire roll 4 passes through the mounting shell 2 and extends to the inside of the unwinding assembly 5. In order to facilitate the welding of the battery cell module acquisition line, an electric arc iron is also provided so that the solder wire can be heated and melted by the electric arc iron.

[0028] In one embodiment, a threaded rod 16 is inserted and installed on the top of the height adjustment frame 6, and the bottom of the threaded rod 16 is fixedly connected to the wire guide cylinder 7. A wing nut 17 threadedly connected to the threaded rod 16 is provided on the top surface of the height adjustment frame 6, and guide rods 19 are welded to both sides of the inside of the height adjustment frame 6. A guide ear 18 is welded to the left and right sides of the wire guide cylinder 7, and the guide ear 18 is sleeved with the guide rod 19. With this structure, the height of the solder wire in the wire guide cylinder 7 can be adjusted, thereby meeting the welding requirements of battery cell modules of different sizes.

[0029] In one embodiment, the housing 2 is a cylindrical structure, and several cylinders 8 are welded around the open end of the housing 2. Each cylinder 8 has a stop bar 9 rotatably mounted on its surface. This structure facilitates the positioning of the welding wire coil 4. The surface of the cylinder 8 has an annular groove corresponding to the stop bar 9. The stop bar 9 is connected to the annular groove of the cylinder 8, and a rubber ring is used to prevent the stop bar 9 from rotating.

[0030] In one embodiment, a flared horn 15 is welded to one end of the wire guide drum 7 facing the unwinding assembly 5, and an upward-opening elbow is provided at the other end of the wire guide drum 7 facing away from the unwinding assembly 5. The flared horn 15 is used to prevent the solder wire from contacting the port of the wire guide drum 7 during the height adjustment stage, thus preventing breakage.

[0031] In one embodiment, a square plug is provided at one end of the hand crank 14, and the square plug is inserted into the square notch of the connecting sleeve 13. This structure makes it easy to install and remove the hand crank 14.

[0034] Working principle: First, the welding wire coil 4 is placed on the central column 3 of the housing 2. Then, the abutment bar 9 on the surface of the cylinder 8 is rotated so that the abutment bar 9 contacts the side of the welding wire coil 4, limiting the welding wire coil 4. Then, the solder wire on the welding wire coil 4 extends out from the wire outlet 20 and extends between the upper guide wheel 10 and the lower guide wheel inside the unwinding assembly 5. As the hand crank 14 drives the upper guide wheel 10 to rotate, the lower guide wheel 11 rotates with the upper guide wheel 10, realizing the unwinding of the welding wire coil 4 until... Solder wire extends from the end of the wire guide tube 7 and reaches the solder joint of the battery cell module acquisition line. In conjunction with the use of the galvanizing iron, the battery cell module acquisition line is soldered. At the same time, since the threaded rod 16 installed on the height adjustment frame 6 is connected to the wire guide tube 7, by rotating the wing nut 17 threaded to the threaded rod 16, the threaded rod 16 is raised during the upward process, so that the height of the solder wire in the wire guide tube 7 can be adjusted, thereby meeting the welding requirements of battery cell modules of different sizes.
