[0002] Stud welding is a method of contacting one end of the stud with the surface of the plate (or pipe), energizing the arc, and after the contact surface melts, applying a certain pressure to the stud to complete the welding. Stud welding is a type of arc welding, which is mainly divided into two forms. One is the drawn arc stud welding machine, in which the arc is generated by the lifting action of the welding gun and the pilot current; the other is the capacitor energy storage stud welding machine, also known as the tip discharge stud welding machine, in which the arc is generated by the instantaneous melting of the special welding tip of the welding stud by a large current.

[0003] When welding sheet metal parts of electric control cabinets, studs are usually welded to sheet metal parts with thin plate shapes. Sheet metal parts with thin plate structures are not only easy to deform during transportation, but also easy to cause scratches to personnel, making manual loading and unloading inconvenient and affecting welding efficiency.

[0035] Example 1

[0036] See also Figure 1-4 The present invention provides a technical solution: an automatic welding and assembly device for sheet metal parts of an electric control cabinet, comprising:

[0037] The welding machine body 1 comprises a machine table 11, a Y-axis mover 12, a support frame 13, an X-axis mover 14, a mounting seat 15 and a stud welder 16. An insulating platform 111 is provided on the surface of the machine table 11, the Y-axis mover 12 is provided on one opposite side of the machine table 11, the support frame 13 is fixedly mounted on the moving seat of the Y-axis mover 12, the X-axis mover 14 is fixedly mounted on the support frame 13, the mounting seat 15 is fixedly mounted on the moving seat of the X-axis mover 14, and the stud welder 16 is fixedly mounted on the mounting seat 15;

[0038] The adsorption module includes a sliding seat 2, a Z-axis driving cylinder 3, a rotating motor 4 and an adsorption plate 5. The sliding seat 2 is slidably connected to the mounting seat 15, the Z-axis driving cylinder 3 is fixedly installed on the mounting seat 15, the output end of the Z-axis driving cylinder 3 is connected to the sliding seat 2, the rotating motor 4 is fixedly installed on the sliding seat 2, the output end of the rotating motor 4 is connected to the rotating rod 41, the bottom of the rotating rod 41 is connected to the adsorption plate 5, and a plurality of suction cups 51 are arranged on the adsorption plate 5.

[0039] The insulating platform 111 is a bakelite board. Specifically, the insulating platform 111 is a bakelite board with a plurality of "T"-shaped grooves on the surface to ensure the insulating effect.

[0040] Working principle: When welding the sheet metal parts of the electric control cabinet, the sheet metal parts in the shape of metal sheets are placed on the insulating platform 111, and then stud welding is performed by the stud welding machine 16. The stud welding machine 16 realizes Y-axis and X-axis movement through the Y-axis mover 12 and the X-axis mover 14 to perform multi-point welding. The adsorption module moves synchronously with the stud welding machine 16 on the mounting seat 15, so that after the stud welding machine 16 finishes welding the sheet metal parts of the electric control cabinet, the position of the adsorption module corresponds to the sheet metal parts of the electric control cabinet. Afterwards, the adsorption plate 5 rotates 180 degrees driven by the rotating rod 41 at the output end of the rotating motor 4, and then the Z-axis driving cylinder 3 drives the sliding seat 2 and the rotating motor 4 thereon to move downward, so that the suction cup 51 of the adsorption plate 5 adsorbs the sheet metal parts of the electric control cabinet, and rotates 180 degrees in the opposite direction, so that the sheet metal parts of the electric control cabinet are transferred to the back side of the support frame 13, and the unloading of thin plate structure products is realized.

[0041] On the one hand, the adsorption module can realize the unloading of thin plate structure products. On the other hand, the electric control cabinet sheet metal parts can be transferred to the rear side of the support frame 13 during unloading, which does not affect the loading of the electric control cabinet sheet metal parts to be welded on the front side of the support frame 13. The loading and unloading efficiency is high, and the welding efficiency is effectively improved.

[0042] Example 2

[0043] Based on the above embodiments, this embodiment further makes the following improved technical solutions: a first slide rail 52 is provided on the adsorption plate 5, the bottom of the rotating rod 41 is slidably connected to the first slide rail 52, the electric push rod 6 is fixedly installed on the adsorption plate 5, and the end of the piston rod 61 of the electric push rod 6 is connected to the rotating rod 41.

[0044] The end of the piston rod 61 is fixed to the rotating rod 41, so that the rotating rod 41 can adjust the distance between it and the electric push rod 6, that is, the rotating rod 41 can adjust its position on the adsorption plate 5, so that when the sheet metal parts of the electric control cabinet are welded and unloaded, the rotation center of the adsorption plate 5 is different, and the adsorption position of the suction cup 51 is adjusted to cope with the adsorption and unloading requirements of sheet metal parts of electric control cabinets of different sizes.

[0045] Example 3

[0046] This embodiment further provides the following improved technical solution based on the above embodiment: a plurality of mounting holes 53 arranged in an array are provided on the adsorption plate 5 , and the suction cup 51 is provided in the mounting hole 53 .

[0047] The plurality of mounting holes 53 arranged in an array on the adsorption plate 5 allow the number of suction cups 51 to be flexibly adjusted according to demand to meet the demand for adsorption and unloading.

[0048] Example 4

[0049] Based on the above embodiments, this embodiment further provides the following improved technical solutions: a second slide rail 131 is provided on the support frame 13, the reinforcement seat 7 is slidably connected to the second slide rail 131, a bearing 71 is provided on the reinforcement seat 7, and the rotating rod 41 is passed through the bearing 71.

[0050] The bearing 71 sleeved on the rotating rod 41 can effectively support and position the rotating rod 41 to ensure the smooth rotation of the adsorption plate 5, and the sliding of the reinforcement seat 7 on the support frame 13 can be used to always maintain the support and positioning of the rotating rod 41.

[0051] Symmetrically arranged reinforcement rods 72 are provided on both sides of the bearing 71 , one end of the reinforcement rod 72 is fixedly mounted on the outer ring of the bearing 71 , and the other end opposite to the reinforcement rod 72 is fixedly mounted on the reinforcement seat 7 , so as to effectively support and position the rotating rod 41 .

[0052] Example 5

[0053] This embodiment further provides the following improved technical solution based on the above embodiment: symmetrically arranged distance sensors 8 are provided at both ends of the second slide rail 131 .

[0054] The distance sensor 8 is used to monitor the distance between the bearing 71 and the machine table 11. When the distance is less than the set installation distance, the rotating motor 4 is prohibited from driving the adsorption plate 5 to rotate and adsorb the sheet metal of the electric control cabinet to avoid collision damage during the rotation of the sheet metal of the electric control cabinet. Instead, the Y-axis mover 12 is used to drive the support frame 13 to move so that the adsorption plate 5 is aligned with the sheet metal of the electric control cabinet to achieve adsorption and unloading.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
