[0031] An embodiment of the present invention provides an inflatable cabinet welding system, including a welding room 1, a welding robot arm 2, a support base 3, a first positioning mechanism 4 and a second positioning mechanism 5. The welding robot arm 2 and the support base 3 are both arranged in the welding room 1, the support base 3 is used to place the inflatable cabinet 100, two first positioning mechanisms 4 and two second positioning mechanisms 5 are both arranged on the support base 3, the two first positioning mechanisms 4 are respectively used to abut against two opposite side walls of the inflatable cabinet 100, and the two second positioning mechanisms 5 are respectively used to abut against the other two opposite side walls of the inflatable cabinet 100.

[0032] In this optional embodiment, if Figure 1 and Figure 2As shown, by setting the first positioning mechanism 4 and the second positioning mechanism 5, it can be ensured that the position of the inflatable cabinet 100 on the support seat 3 is accurately fixed, thereby improving the accuracy during welding and ensuring the welding quality. The inflatable cabinet 100 is abutted against the support seat 3 through two first positioning mechanisms 4 and two second positioning mechanisms 5, thereby improving the stability of the inflatable cabinet 100 during welding and reducing welding defects caused by vibration or movement during welding. Since the first positioning mechanism 4 and the second positioning mechanism 5 are respectively used to abut two pairs of opposite side walls of the inflatable cabinet 100, the welding system can adapt to inflatable cabinets 100 of different sizes. The welding robot arm 2 is arranged in the welding room 1, which improves welding efficiency and safety.

[0033] Furthermore, two support seats 3 are provided, and the first positioning mechanism 4 and the second positioning mechanism 5 are provided on the two support seats 3 , and the welding robot arm 2 is provided between the two support seats 3 .

[0034] In this optional embodiment, combined with Figure 2 As shown, welding operations at two workstations can be implemented through two support bases 3, that is, after the welding of the inflatable cabinet 100 on the first support base 3 is completed, the welding robot arm 2 turns to the second support base 3, welds the inflatable cabinet 100 on the second support base 3, and then lifts away the inflatable cabinet 100 welded on the first support base 3, and then lifts the inflatable cabinet 100 to be welded to the first support base 3 again, thereby realizing continuous and uninterrupted welding operations.

[0035] Optionally, the first positioning mechanism 4 and the second positioning mechanism 5 have the same structure.

[0036] Furthermore, the first positioning mechanism 4 includes an L-shaped rod 41 and a driving device 45. The L-shaped rod 41 has a horizontal portion and a vertical portion. The horizontal portion is slidably connected to the upper surface of the support seat 3. The driving device 45 is drivingly connected to the horizontal portion so that the vertical portion moves toward the corresponding side wall of the inflatable cabinet 100. The first positioning mechanism 4 also includes a cross bar 44. Two L-shaped rods 41 are provided. Both ends of the cross bar 44 are connected between the two L-shaped rods 41. The driving device 45 is drivingly connected to the cross bar 44 so that the two L-shaped rods 41 move synchronously toward the corresponding side walls of the inflatable cabinet 100.

[0037] Specifically, the driving device 45 can be a hydraulic cylinder, the output end of the hydraulic cylinder is connected to the cross bar 44, and the cross bar 44 is pushed to move by starting the hydraulic cylinder, thereby driving the horizontal parts of the two L-shaped rods 41 to move along the upper surface of the support seat 3 until the vertical part of the L-shaped rod 41 abuts against the corresponding side wall of the inflatable cabinet 100. It should be noted that the horizontal part of the L-shaped rod 41 is the part along the X-axis direction, and the vertical part of the L-shaped rod 41 is the part along the Z-axis direction.

[0038] Furthermore, the first positioning mechanism 4 further includes an oblique support rod 42, and both ends of the oblique support rod 42 are connected between the horizontal portion and the vertical portion.

[0039] In this optional embodiment, combined with Figure 1 and Figure 2 As shown, the diagonal support rod 42 plays a role similar to that of a reinforcing rib, thereby improving the structural strength of the L-shaped rod 41 and further improving the abutment and positioning effect of the L-shaped rod 41 on the side wall of the inflatable cabinet 100.

[0040] Optionally, the first positioning mechanism 4 also includes a buffer unit 43, and multiple buffer units 43 are arranged on a side surface of the vertical part facing the center direction of the support seat 3. The buffer unit 43 includes a moving rod 431, a spring 432 and a rubber block 433. A groove 411 is provided on one side surface of the vertical part facing the center direction of the support seat 3, and a through hole 412 is provided from the bottom surface of the groove 411 to the other side of the vertical part. The rubber block 433 is slidably connected in the groove 411, one end of the moving rod 431 is connected to the rubber block 433, and the other end of the moving rod 431 passes through the through hole 412. The spring 432 is sleeved on the moving rod 431, and the two ends of the spring 432 respectively abut against the opposite surfaces of the rubber block 433 and the groove 411. When the spring 432 is in a natural state, at least part of the rubber block 433 extends out of the groove 411.

[0041] In this optional embodiment, combined with Figure 3 , Figure 4 , Figure 5 and Figure 6 When the spring 432 is in the natural state, at least part of the rubber block 433 extends out of the groove 411, that is, Figure 3 As shown, at this time, the L-shaped rod 41 has not yet abutted against the side wall of the inflatable cabinet 100. When the L-shaped rod 41 moves toward the side wall of the inflatable cabinet 100, the rubber block 433 first abuts against the side wall of the inflatable cabinet 100, and the spring 432 is gradually compressed, and pushes the moving rod 431 to move away from the side wall of the inflatable cabinet 100. During this process, the contact between the rubber block 433 and the side wall of the inflatable cabinet 100 is flexible contact (non-rigid contact), thereby avoiding the instantaneous impact force of the L-shaped rod 41 on the side wall of the inflatable cabinet 100, preventing the thinner side wall of the inflatable cabinet 100 from being pressed into a concave state, avoiding the defect problem of the side wall of the inflatable cabinet 100, and improving the welding quality of the inflatable cabinet 100, until the rubber block 433 is completely retracted into the groove 411. Figure 5 As shown, at this time, the flexible contact is transformed into a rigid positioning of the side wall of the inflatable cabinet 100.

[0042] Optionally, a slot 421 is provided on the diagonal support rod 42 , and when the rubber block 433 is completely in the groove 411 , one end of the moving rod 431 away from the rubber block 433 is inserted into the corresponding slot 421 .

[0043] In this optional embodiment, combined with Figure 5 and Figure 6 When the rubber block 433 is completely in the groove 411, that is, the rubber block 433 is completely retracted into the groove 411, at this time, the vertical portion of the L-shaped rod 41 is rigidly in contact with the side wall of the inflatable cabinet 100, so that the surrounding side walls of the inflatable cabinet 100 are completely positioned. In the process of the rubber block 433 retracting into the groove 411, the moving rod 431 gradually moves away from the inflatable cabinet 100 until the moving rod 431 is inserted into the groove 411, thereby further increasing the structural strength of the diagonal support rod 42 through the moving rod 431, thereby improving the rigid positioning effect of the vertical portion of the L-shaped rod 41 on the side wall of the inflatable cabinet 100.

[0044] The embodiment of the present invention further provides a gas cabinet welding method, based on the above gas cabinet welding system, comprising the following steps:

[0045] S1: hoisting the inflatable cabinet 100 to the upper surface of the support base 3;

[0046] S2: The two first positioning mechanisms 4 are respectively abutted against two opposite side walls of the inflatable cabinet 100, and the two second positioning mechanisms 5 are respectively abutted against the other two opposite side walls of the inflatable cabinet 100;

[0047] S3: The welding robot arm 2 starts welding the inflatable cabinet 100.

[0048] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
