DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 7 As shown:

[0023] Embodiment 1: The utility model provides a welding engineering device based on new energy technology, comprising: a guide frame mechanism 1, comprising a guide frame assembly 11, and a battery arrangement frame 12 slidably arranged on the front side of the guide frame assembly 11; a welding mechanism 2, comprising a lifting assembly 21 installed on the guide frame assembly 11, a welding assembly 22 slidably embedded in the front side of the lifting assembly 21, and a limit assembly 23 arranged at the bottom of the lifting assembly 21;

[0024] Among them, a number of batteries 3 are placed in the battery arrangement rack 12, and then the aluminum strip is placed on the upper side of the batteries. During operation, the lifting component 21 is controlled to drive the welding component 22 to move downward, so that the aluminum strip is spot-welded and fixed on the battery 3. By pushing the battery arrangement rack 12, the several batteries 3 and the aluminum strip can be moved together, so that it is convenient for the staff to perform spot welding in sequence. When the welding is completed, the welding component 22 can be pushed to move it close to the lifting component 21. The movement of the welding component 22 will be stuck in the limiting component 23 and thus be fixed. At this time, spot welding can be performed again to form a second row of welding points on the aluminum strip to avoid the situation of false welding during one spot welding. When the welding is completed, pulling the limiting component 23 downward can reset the welding component 22, so as to facilitate the switching of the spot welding position.

[0025] Specifically, the guide frame assembly 11 includes a guide rod 111 , the lower end of the guide rod 111 is fixedly connected to a U-shaped guide frame 112 , the upper end of the guide rod 111 is fixedly connected to a mounting plate 113 , and the battery arrangement frame 12 is arranged on the front side of the U-shaped guide frame 112 .

[0026] Specifically, the lifting assembly 21 includes a cylinder 211, the bottom of the cylinder 211 is fixedly connected to an L-shaped slider 212, the front side of the L-shaped slider 212 is fixedly connected to a group of guide rods 213, and the outer side of the guide rods 213 is sleeved with a spring 214; the welding assembly 22 includes a T-shaped slider 221 and a welding pen 222, and the bottom of the T-shaped slider 221 is fixedly connected to an extension plate 223.

[0027] Specifically, the welding pen 222 is fixedly installed on the T-shaped slider 221 after being penetrated by the screw rod, the T-shaped slider 221 is limited and slidably embedded in the L-shaped slider 212, the welding pen 222 is limited and slidably embedded in the guide rod 213, and the spring 214 drives the welding pen 222 away from the L-shaped slider 212.

[0028] As can be seen from the above, a number of batteries 3 are placed in the battery arrangement rack 12. When the battery arrangement rack 12 slides on the front side of the U-shaped guide rack 112, it can play a guiding role, thereby facilitating the staff to perform spot welding operations. The control cylinder 211 can make the L-shaped slider 212 drive the T-shaped slider 221 and the welding pen 222 to descend. The descent of the welding pen 222 can enable the welding needle clamped on the welding pen 222 to spot weld the surface of the aluminum strip.

[0029] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the bottom of the L-shaped slider 212 is also fixedly connected to a guide rod 215, and a spring 216 is sleeved on the outer side of the guide rod 215; the limiting assembly 23 includes a connecting rod 231, the upper end of the connecting rod 231 is fixedly connected to an L-shaped guide block 232, the lower end of the connecting rod 231 is fixedly connected to a pressure plate 233, and the L-shaped guide block 232 is also fixedly connected to a trapezoidal positioning block 234.

[0030] Specifically, the L-shaped guide block 232 is limitedly slidably embedded on the second guide rod 215 , the second spring 216 drives the L-shaped guide block 232 to approach the L-shaped slider 212 , and the trapezoidal positioning block 234 can limit the extension plate 223 .

[0031] As can be seen from the above, pushing the soldering pen 222 causes the T-shaped slider 221 to slide on the L-shaped slider 212. At the same time, the soldering pen 222 will slide on the guide rod 1 213, causing the spring 1 214 to be compressed on the L-shaped slider 212. When the extension plate 223 moves, the trapezoidal positioning block 234 will drive the L-shaped guide block 232 to move downward, and the spring 216 will be compressed on the guide rod 215. When the extension plate 223 passes over the trapezoidal positioning block 234, the spring 216 will reset, causing the extension plate 223 to be pressed by the trapezoidal positioning block 234. The positioning block 234 is limited, thereby playing a positioning role. After the extension plate 223 is positioned, the position of the welding pen 222 will also be fixed, so that the staff can perform secondary spot welding operations conveniently. After the spot welding is completed, pulling down the pressure plate 233 will cause the connecting rod 231 to drive the L-shaped guide block 232 to move downward. The downward movement of the L-shaped guide block 232 will cause the trapezoidal positioning block 234 to break away from the limit on the extension plate 223. The welding pen 222 will move away from the L-shaped slider 212 under the reset drive of the spring 1 214, which is convenient for the next spot welding operation.
