[0019] The following description is only used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.

[0020] [Example 1]

[0021] An automatic welding line, such as Figure 1-Figure 3 , including a bottom cover supply mechanism 1, a robotic arm 2, a center positioning mechanism 3, a liquid storage cylinder supply mechanism, a press-fitting and welding integrated machine 6 and a leak tester 7. The bottom cover supply mechanism 1 is used to supply the bottom cover assembly. The robotic arm 2 transfers the bottom cover assembly to the center positioning mechanism 3 to center the bottom cover assembly. The robotic arm 2 transfers the liquid storage cylinder and the bottom cover assembly to the press-fitting and welding integrated machine 6 for press-fitting and welding operations. After the welding is completed, the robotic arm 2 transfers the product to the leak tester 7 for sealing detection.

[0022] The welding automatic line also includes a transfer rack 8, and the robot arm 2 transfers the completed products to the transfer rack 8, and the transfer rack 8 is used to place the products after the inspection. Figure 3The transfer rack 8 is provided with a plurality of insertion rods 81 , and the products are inserted into the insertion rods 81 and placed. Furthermore, the transfer rack 8 is installed on the steering machine 9 .

[0023] The bottom cover supply mechanism 1 , the center positioning mechanism 3 , the liquid storage cylinder supply mechanism, the press-fit welding seam integrated machine 6 , the leak tester 7 and the sequence transfer rack 8 are arranged around the robotic arm 2 with the robotic arm 2 as the center.

[0024] Specifically, the bottom cover supply mechanism can adopt belt line supply, material basket supply, spiral conveyor and the like. The bottom cover should be in a uniform posture during supply to facilitate grabbing by the robot. The liquid storage cylinder supply mechanism includes a hoist 4 and a transfer platform 5. After the hoist 4 lifts the liquid storage cylinder to the highest height, the liquid storage cylinder rolls to the grabbing position of the robot arm through the inclined surface of the transfer platform 5. Preferably, the liquid storage cylinder supply mechanism also includes a counting device 51, such as a photoelectric sensor or an infrared sensor, such as Figure 4 The center positioning mechanism 3 includes a positioning push block 31 and a positioning drive assembly 32. The positioning push blocks 31 are symmetrically arranged, and the end faces on the opposite sides are V-shaped end faces. The bottom cover assembly is placed between the positioning push blocks 31 for positioning. The positioning drive assembly 32 generally uses a cylinder.

[0025] Optionally, the walls 52 on both sides of the inclined ramp of the transfer platform 5 are connected to the cylinder, and the spacing can be adjusted to adapt to the length of the liquid storage cylinder.

[0026] The working steps are as follows: the bottom cover lifting ring assembly is clamped by the robot arm 2 and placed on the center positioning mechanism 3, the two cylinders of the positioning drive assembly 32 are pushed out, and after the positioning push block 31 clamps the bottom cover, the center of the bottom cover will be positioned at a certain point.

[0027] After the liquid storage cylinder is placed in the lifting machine 4, the liquid storage cylinder is separated individually through the lifting machine and the transfer platform 5 to facilitate the clamping of the mechanical arm 2.

[0028] The press-fit seam welding machine 6 includes a welding mechanism 61 and a press-fit mechanism 62. After the robot arm 2 clamps the liquid storage cylinder, it is placed on the press-fit mechanism 62 station of the press-fit seam welding machine 6, and then goes to the center positioning mechanism 3 to clamp the bottom cover ring assembly, and also places it on the press-fit mechanism 62. The press-fit mechanism 62 is pushed to the working position by the cylinder, and the bottom cover ring assembly is pressed into the liquid storage cylinder by the press, and then the seam welding begins. After completion, the product is clamped out by the robot arm 2 and placed in the leak tester 7 to detect the sealing. After the test, it is placed on the transfer rack 8. When one side of the transfer rack is full, the steering machine 9 rotates the direction to place it on the other side of the transfer rack 8.

[0029] Embodiment 2, based on embodiment 1, the bottom cover supply mechanism 1 includes a sorting machine, which is used to adjust the posture of the bottom cover assembly, such as adjusting the parts to the bottom cover at the bottom and the lifting ring at the top to unify their directions. The sorting machine can use the shape of the bottom cover to adjust the posture, such as setting an image recognition mechanism and a sorting robot mechanism, and placing the bottom cover assembly on a conveyor after adjusting its posture. It can also use a cylinder to lift up a basket of bottom cover lifting ring assemblies one by one according to the shape of the bottom cover. Since the bottom cover and the lifting ring are different in size and volume, there will be a limiter tool equipped with infrared sensing. The lifted part must be the lifting ring and not the bottom cover, thus ensuring the direction of the bottom cover lifting ring, and then the conveyor is used to transmit it for the robot to grab.
