[0022] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: a rapid continuous resistance welding device for battery caps, which includes a support frame 1. A gantry 3 is fixedly connected to the top of the support frame 1. A resistance welder 4 is arranged at the inner bottom of the gantry 3. A motor 2 is fixedly connected to the bottom of the support frame 1; a rotating assembly 5 is arranged on the top of the support frame 1. The rotating assembly 5 includes a turntable 501. A rotating rod 509 is fixedly connected to the bottom of the turntable 501. The bottom of the rotating rod 509 is fixedly connected to the output end of the motor 2. A plurality of placing blocks 506 are fixedly connected to the top of the turntable 501 at equal intervals near the edge. A supporting plate 507 is fixedly connected to the inner surface of each of the plurality of placing blocks 506. A hollow block 503 is fixedly connected to the center of the top of the turntable 501. A plurality of tubes 505 are arranged on the outer surface of the hollow block 503 at equal intervals. The tubes 505 are in communication with the hollow block 503. The outer surfaces of the plurality of tubes 505 respectively penetrate through the outer surfaces of the plurality of placing blocks 506 at positions far from the hollow block 503. A vacuum generator 504 is arranged on the top of the hollow block 503. The hollow block 503 is in communication with the vacuum generator 504; an installation assembly 6 is fixedly connected to the top of the support frame 1. The installation assembly 6 includes an installation plate 601.

[0024] As Figure 1 and Figure 5 shown, a plurality of support columns 602 are fixedly connected to the bottom of the installation plate 601 at equal intervals. The bottoms of the plurality of support columns 602 are fixedly connected to the top of the support frame 1, which is convenient to fixedly connect the installation plate 601 to the top of the support frame 1 through the plurality of support columns 602.

[0025] As Figure 3 shown, a plurality of air holes 508 are opened at equal intervals on the top of the supporting plate 507. The supporting plate 507 is located at the middle position of the placing block 506, which is convenient to adsorb and fix the upper battery cap through the plurality of air holes 508 when the negative pressure in the lower cavity of the placing block 506 acts on the upper battery cap when the battery cap is placed above the supporting plate 507.

[0026] As Figures 1-3 -4 shown, a plurality of touch rods 502 are fixedly connected to the bottom of the turntable 501 at equal intervals near the edge. A travel switch 603 is fixedly connected to the top of the installation plate 601 near the edge. The travel switch 603 is set in a matching manner with the touch rods 502. When the plurality of touch rods 502 sequentially toggle the travel switch 603, the travel switch 603 sends an instruction to the motor 2 to make it stop driving briefly, which is convenient for the plurality of placing blocks 506 to stay below the resistance welder 4 in sequence.

[0027] As Figure 1 and Figure 5As shown, a circular groove 604 is formed near the edge at the top of the mounting disc 601. A plurality of contact rods 502 are all located inside the circular groove 604. When the turntable 501 rotates, the plurality of contact rods 502 fixedly connected to the bottom thereof move synchronously in the circular groove 604, preventing the plurality of contact rods 502 from colliding with the top of the lower mounting disc 601 when the turntable 501 rotates.

[0028] As Figures 1-2 and Figure 4 shown, the output end of the motor 2 rotates through the outer surface of the support frame 1, and the outer surface of the rotating rod 509 is rotatably connected to the inner surface of the mounting disc 601. When the motor 2 drives the rotating rod 509, the outer surface of the rotating rod 509 rotates synchronously inside the mounting disc 601, driving the turntable 501 above it to rotate synchronously.

[0029] As Figures 1-2 shown, the turntable 501 is located above the mounting disc 601, and the spot welder 4 is located near one edge above the turntable 501. The spot welder 4 is matched with the position of the placing block 506. When the turntable 501 rotates, it stays briefly below the spot welder 4 in turn, and the spot welder 4 performs spot welding operations on the battery caps in the lower placing block 506.

[0030] Usage method and working principle of this device: During the resistance welding operation of the battery cap, first manually place the battery caps to be resistance welded into the placing blocks 506 one by one in the part of the turntable 501 close to the left side. Subsequently, two robotic arms symmetrically arranged at the top of the support frame 1, one of which is a loading robotic arm, adsorbs and grabs the battery caps turned over by the external vibrating bowl and sends them into the adjacent placing blocks 506. Then start the vacuum generator 504. The vacuum generator 504 quickly discharges the gas in the hollow block 503. The hollow block 503 is respectively connected to a plurality of placing blocks 506 through a plurality of pipe bodies 505, so that a negative pressure is generated in the lower layer cavity of the placing block 506, and the battery caps on the top of the supporting plate 507 are adsorbed and fixed through a plurality of air holes 508. Start the motor 2. The output end of the motor 2 rotates clockwise. When the turntable 501 is driven to rotate clockwise above the support frame 1 through the rotating rod 509, a plurality of contact rods 502 fixedly connected to the bottom of the turntable 501 move synchronously inside the annular groove 604 and sequentially toggle the lever of the travel switch 603. After the lever of the travel switch 603 is triggered, it sends an instruction to the motor 2 to pause driving. At this time, the placing block 506 containing the battery cap is located below the resistance welder 4. The resistance welder 4 utilizes the short pause time of the turntable 501 to quickly perform the resistance welding operation on the battery cap below. Then the motor 2 resumes driving and drives the turntable 501 to continue rotating clockwise. The other unloading robotic arm takes out the resistance-welded battery caps. In this way, the process is repeated. A plurality of placing blocks 506 containing battery caps stay below the gantry 3 in turn, and the resistance welder 4 performs continuous resistance welding operations, improving the resistance welding efficiency of the battery caps. It solves the problem in the background technology that during the process of taking and placing the battery caps, the resistance welder is in an idle state, resulting in a long waiting time for taking and placing materials and inability to continuously and quickly perform the resistance welding operation on the battery caps, affecting the resistance welding efficiency of the battery caps.
