Technical Field

[0001] This application relates to the field of soldering technology and equipment, and in particular to a lithium battery soldering machine. Background Technology

[0002] Lithium-ion batteries are rechargeable batteries that store and release energy by moving lithium ions between positive and negative electrodes. They are the core of modern portable electronic devices and new energy technologies, and their performance and application range continue to expand with technological advancements. Currently, in the production and assembly of lithium-ion batteries, the circuit boards mounted on top of the batteries need to be soldered. Currently, soldering circuit boards typically uses an assembly line process, where lithium-ion batteries are placed one by one on a conveyor belt and transported to a soldering machine for soldering. After soldering, they are transported to the next stage. Regarding the aforementioned related technologies, the inventors believe that using an assembly line for soldering lithium-ion battery circuit boards results in low soldering efficiency, as only one lithium-ion battery can be soldered at a time. Utility Model Content

[0004] The lithium battery soldering machine provided in this application adopts the following technical solution:

[0005] A lithium battery soldering machine includes an installation platform, a feeding conveyor, an output conveyor, at least two soldering devices, and a transfer device for transferring lithium batteries.

[0006] By adopting the above technical solution, when soldering the circuit board above the lithium battery, the operator first places the lithium battery to be soldered on the feeding conveyor. When the lithium battery is transported from the feeding conveyor to the transfer area, the transfer device in the transfer area moves the robotic arm above the lithium battery, and the first clamping member at the end of the robotic arm clamps it. The transfer device then transfers the lithium battery to the soldering base of the soldering device by moving the robotic arm. When the robotic arm moves above the soldering base, the second clamping member at the end of the robotic arm first holds the already soldered circuit board. The lithium battery is clamped and then placed on the soldering stand. Finally, the transfer device uses a moving robotic arm to transfer the soldered lithium battery to the discharge conveyor. Since the soldering stand can move the lithium battery back and forth, the soldering components located above the soldering stand can slide left and right and rise and fall, allowing the soldering device to solder different parts of the circuit board above the lithium battery. By arranging at least two soldering devices, multiple soldering devices can perform soldering operations simultaneously, which helps to improve the soldering efficiency of the lithium battery soldering machine on the circuit board above the lithium battery.

The specific structure of the first driving mechanism is disclosed. By setting the first linear module on the top surface of the mounting platform and installing the mounting plate on the sliding platform of the first linear module, the soldering base can slide back and forth above the mounting platform along the arrangement direction of the first linear module, thereby helping to improve the soldering efficiency of the soldering device on the circuit board in the lithium battery.

By horizontally arranging the second linear module on the side wall of the support beam of the soldering bracket and installing the lifting mechanism on the sliding platform of the second linear module, the lifting mechanism can slide left and right along the arrangement direction of the second linear module on the side wall of the support beam. This helps the soldering device to solder different parts of the lithium battery circuit board, thereby improving the soldering efficiency of the soldering device on the circuit board in the lithium battery.

[0017] Optionally, the lifting mechanism includes a vertically arranged third linear module and a sliding platform mounted on the third linear module and extending downwards, with the soldering assembly mounted on the extension bracket.

[0038] Reference Figure 3 and Figure 4 The first drive mechanism 42 is a first linear module 421 mounted on the top surface of the mounting platform 1 and arranged in the front-to-back direction. The soldering base 41 includes a mounting base plate 411 mounted on the sliding platform of the first linear module 421 and a mounting seat 412 detachably mounted on the mounting base plate 411.

The soldering base 41 is locked to the top of the sliding platform of the first linear module 421, so that the soldering base 41 can slide back and forth below the soldering assembly 44.

[0039] Reference Figure 3 and Figure 4The mounting base 412 has an arrangement groove 413 at its top for arranging lithium batteries. The arrangement groove 413 has a limiting side 4131 for the lithium battery to abut against. The mounting base 412 is equipped with a limiting plate 414 that is slidably arranged in the arrangement groove 413 and used to clamp the lithium battery onto the limiting side 4131.

[0040] Reference Figure 3 The soldering bracket 43 includes a first column 431 located on one side of the soldering base 41, a second column 432 located on the other side of the soldering base 41, and a bracket beam 433 connecting the tops of the first column 431 and the tops of the second column 432. The second drive mechanism 45 is a second linear module 451 mounted on the bracket beam 433 and arranged horizontally.

In this embodiment, both the second linear module 451 and the third linear module 461 are lead screw linear modules.

[0041] The implementation principle of a lithium battery soldering machine according to an embodiment of this application is as follows: When soldering lithium batteries, the operator first places the lithium battery to be soldered at the input end of the feeding conveyor 2. When the lithium battery is transported to the transfer area by the feeding conveyor 2, the transfer device 5 located in the transfer area will transfer the lithium battery to the soldering base 41 of one of the soldering devices 4 by controlling the first clamping member 522 at the end of the robotic arm 51; when the robotic arm 51 moves above the soldering base 41, the second clamping member 523 located at the end of the robotic arm 51 will first clamp the lithium battery that has been soldered, and then place the lithium battery to be soldered on the soldering base 41; finally, the transfer device 5 will transfer the lithium battery to the soldering base 41 by moving the robotic arm 51. The lithium batteries that have been soldered are transferred to the discharge conveyor 3. When the lithium batteries to be soldered are arranged in the arrangement slot 413 of the mounting base 412, the drive cylinder 415 will drive the limiting plate 414 to move forward and cooperate with the limiting side plate to clamp the lithium batteries. Then the soldering component 44 will solder the circuit board on the surface of the lithium batteries. Since the soldering base 41 can drive the lithium batteries to slide back and forth, the soldering component 44 located above the soldering base 41 can slide left and right and rise and fall, so that the soldering device 4 can solder different parts of the circuit board above the lithium batteries. By arranging four soldering devices 4 to perform soldering operations simultaneously, it helps to improve the soldering efficiency of the lithium battery soldering machine on the circuit board above the lithium batteries.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
