[0021] Embodiment 1

[0022] like Figure 1 and Figure 2 As shown, a battery terminal welding device proposed in this embodiment includes a frame 1, a high-frequency induction heating device 2, a heating column assembly and a lifting mechanism.

[0023] The frame 1 is provided with a conveying mechanism 10 for horizontally conveying the batteries, and the terminals are pre-placed on the poles at the top of the batteries.

[0024] The high frequency induction heating device 2 is arranged on the frame 1, and the output end of the high frequency induction heating device 2 is connected to a heating coil 3, and the heating coil 3 has two heating stations. There are two heating stations, through which two heating columns 6 pass respectively, so as to heat the ends of the two heating columns 6.

[0025] The heating column assembly includes two heating columns 6 arranged side by side, and the two heating columns 6 can weld two poles and terminals on the battery at the same time.

[0026] The lifting mechanism is arranged on the frame 1, and can drive the end of the heating column 6 to move up to the heating position, and move down to the position of welding the battery pole and terminal. The lifting mechanism includes a mounting frame 5 for vertically mounting the heating column 6 and an electric cylinder 4 for driving the mounting frame 5 to move up and down. The electric cylinder 4 is arranged on the frame 1, and the electric cylinder 4 can drive the mounting frame 5 to move in the vertical direction. The mounting frame 5 drives the heating column 6 to move up and down, thereby moving the heating column 6 to the heating position or the welding position. When the heating column 6 moves up to the heating position, it is heated by the heating coil 3; when the heating column 6 moves down to the welding position, it can melt the battery pole to weld the pole and the terminal together.

[0027] This embodiment has no open flame for heating, is safer, more environmentally friendly, has a stable heating temperature, a fast heating speed and high welding efficiency. The heating coil 3 is heated by the high-frequency induction heating device 2, and then the heating coil 3 is used to heat the heating column 6, and the heating column 6 heats up quickly. After the battery is transported to the welding station by the conveying mechanism 10, the conveying is stopped, and the heating column 6 is driven downward by the lifting mechanism. The high-temperature heating column 6 abuts against the top pole of the battery to melt the lead pole, thereby welding with the terminal. There is no open flame in the entire welding process, the heating temperature of the heating column 6 is stable, and the assembly line welding operation is carried out, which effectively improves the welding efficiency.

[0028] Embodiment 2

[0029] like Figure 1 and Figure 2 As shown, a battery terminal welding device proposed in this embodiment, compared with the first embodiment, in this embodiment, a photoelectric sensing probe 7 is arranged on the frame 1, and the photoelectric sensing probe 7 is located in front of the heating column 6. When the conveying mechanism 10 conveys the battery, the photoelectric sensing probe 7 can detect the battery position and transmit the detection signal to the central control of the entire welding device. The central control controls when the electric cylinder 4 moves and when the conveying mechanism 10 stops conveying the battery, so as to align the heating column 6 with the pole on the top of the battery. The pole is made of lead and melts when heated to weld the battery pole and the terminal together.

[0030] The frame 1 is provided with a horizontally distributed mobile drive mechanism 9, and the output end of the mobile drive mechanism 9 is connected to a positioning frame 8. The positioning frame 8 is a U-shaped structure and the inner sides of both ends of the U-shape are chamfered, which is convenient for introducing the battery into the inner side for horizontal pushing. The mobile drive mechanism 9 is a cylinder or a hydraulic cylinder or an electric push rod. The mobile drive mechanism 9 is controlled by the central control. The mobile drive mechanism 9 can drive the positioning frame 8 to move, and the positioning frame 8 pushes the battery to locate the battery position, so that the heating column 6 can be aligned with the battery pole for heating, and the accuracy of the welding process can be ensured.

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
