[0031] When the device shown in the present invention welds the steam oven inner pot 1, precise clamping and positioning are performed through the pot wall clamping mechanism 2 and the pot bottom clamping mechanism 3, and precise welding is performed at the welding position through the welding robot. The device can adapt to steam oven inner pots 1 products of different sizes, and the pot wall clamping mechanism 2 can clamp the inner pot walls 11 of different sizes, and the pot bottom clamping mechanism 3 can clamp the outer side walls of the inner pot bottom 12 of different sizes, thereby improving the applicability of the device, and the pot wall clamping mechanism 2 and the pot bottom clamping mechanism 3 shown in the device cooperate with the automatic feeding mechanism to realize automatic feeding operation, reduce manual labor intensity, and improve production efficiency.

[0032] It is worth mentioning that the automatic feeding mechanism includes a first transmission belt, a second conveyor belt, a lifting mechanism and an adsorption mechanism.

[0034] The second conveyor belt is used to realize the transmission process of the inner liner bottom 12. The lifting mechanism is installed on the first conveyor belt, and the adsorption mechanism is installed on the second conveyor belt. When the inner liner wall 11 is automatically loaded, the inner liner wall 11 is transmitted to the top of the lifting mechanism through the first conveyor belt, and the lifting mechanism outputs to lift the inner liner wall 11 upward, and the steering robot 4 drives the liner wall clamping mechanism 2 to rotate into place, and pushes the first clamping component 22 forward through the first linear drive component 25, and inserts the first clamping component 22 into the inner liner wall 11. At this time, the first clamping component 22 is in a contracted state, and the lifting mechanism is reset. The first expansion and contraction component 23 output drives the first clamping component 22 to expand outward. At this time, the first clamping component 22 expands outward to clamp the inner side wall of the inner liner wall 11, and the outer wall clamping component 24 outputs to clamp the outer side wall of the inner liner wall 11, thereby realizing the precise positioning and clamping function of the inner liner wall 11. At this time, the steering robot The robot 4 and the first linear drive component 25 are reset, and the inner pot wall 11 is carried to the welding station; the second conveyor belt drives the inner pot bottom 12 to move to the loading station, and the adsorption mechanism adsorbs the inner wall of the inner pot bottom 12 and rotates it to a vertical state. The steering robot 4 drives the pot bottom clamping mechanism 3 to rotate into place, and the second linear drive component 34 outputs to push the second mounting frame 31 outward. At this time, the second expansion and contraction component 33 outputs to synchronously shrink the four clamping plates 32 inward to clamp the four outer walls of the inner pot bottom 12 to achieve precise clamping of the inner pot bottom 12. The steering robot 4 is reset, and the second linear drive component 34 drives the second mounting frame 31 to move outward, and the inner pot bottom 12 clamped in the clamping plate 32 is pressed against the end of the inner pot wall 11 to achieve the connection between the inner pot wall 11 and the inner pot bottom 12, and the inner pot bottom 12 is carried to the welding station. Finally, the welding robot is used to realize the automated welding operation of the steam oven inner pot 1.

The center rod 221 is horizontally fixedly installed at the center of the first mounting frame 21. Four inner wall resistance plates 222 are provided. The four inner wall resistance plates 222 are distributed in a rectangular shape around the center rod 221. The length direction of the inner wall resistance plate 222 is consistent with the length direction of the center rod 221. One end of the inner wall resistance plate 222 is slidably set with the first mounting frame 21. The first mounting frame 21 is provided with a guide groove 211 for the inner wall resistance plate 222 to slide. The end of the inner wall resistance plate 222 away from the first mounting frame 21 is connected to the center rod 221 through the first telescopic plate 223. The first expansion and contraction assembly 23 is transmission-connected with the inner wall resistance plate 222.

[0036] The first clamping assembly 22 also includes a second telescopic plate 224 and a corner contact plate 225. There are four corner contact plates 225, which are respectively located at the four ends of the rectangle formed by the four inner wall contact plates 222. The length direction of the corner contact plate 225 is consistent with the length direction of the inner wall contact plate 222. The two ends of the corner contact plate 225 are respectively connected to the adjacent inner wall contact plate 222 through the second telescopic plate 224.

[0037] When the first expansion and contraction component 23 is driven, the four inner wall contact plates 222 are close to or away from each other to achieve the function of contraction or expansion. The outer wall of the inner wall contact plate 222 can contact the inner wall of the inner liner wall 11. The inner wall contact plate 222 can be driven by the first expansion and contraction component 23 to control the function of contacting or relaxing the inner wall of the inner liner wall 11. The center rod 221 is used to install the first clamping component 22 on the first mounting frame 21. The first telescopic plate 223 and the guide The groove 211 is used to guide and limit the sliding of the inner wall contact plate 222, and the second telescopic plate 224 is used to install the corner contact plate 225 on the side of the inner wall contact plate 222, and to guide and limit the position of the corner contact plate 225. When the inner wall contact plate 222 moves into place, the position of the corner contact plate 225 located at the angle between the two inner wall contact plates 222 is fixed, and the corner contact plate 225 can bear the corner of the inner wall of the inner liner wall 11.

[0038] The first expansion and contraction component 23 includes a first linear driver 231, a transmission plate 232, a sliding cylinder 233 and a first hinged rod 234. The first linear driver 231 is horizontally fixedly installed on the first mounting frame 21. The sliding cylinder 233 is sleeved on the center rod 221. The sliding cylinder 233 and the center rod 221 are slidably arranged. The transmission plate 232 is fixedly connected to the sliding cylinder 233. The output end of the first linear driver 231 is fixedly connected to the sliding cylinder 233. A plurality of first hinged rods 234 are provided. Each inner wall contact plate 222 is hingedly installed with a first hinged rod 234 at both ends along the length direction. The other end of the first hinged rod 234 is hinged to the outer wall of the sliding cylinder 233.

[0039] When the first expansion and contraction component 23 is working, the output of the first linear driver 231 pushes the transmission plate 232, which pushes the sliding cylinder 233 to slide on the center rod 221 through the transmission plate 232. When the sliding cylinder 233 slides, it drives the first hinged rod 234 to deflect. The deflection of the first hinged rod 234 drives the inner wall resistance plate 222 hinged thereto to expand outward or contract inward synchronously, thereby realizing the driving function of the inner wall resistance plate 222, that is, realizing the clamping driving function of the inner liner wall 11.

[0040] The outer wall clamping assembly 24 includes a second linear drive 241, a sliding frame 242, a sliding plate 243, a second hinged rod 244, an outer wall contact plate 245, a limiting rod 246, a telescopic rod 247 and a first spring 248.

[0041] When the outer wall clamping assembly 24 is working, the sliding plate 243 is driven to move forward through the output of the second linear drive 241. When the sliding plate 243 is not in contact with the inner liner wall 11, the sliding frame 242 moves forward synchronously with the sliding plate 243 under the elastic force of the first spring 248 until the sliding frame 242 moves to the maximum displacement. At this time, the sliding plate 243 continues to move forward, and displacement occurs between the sliding plate 243 and the sliding frame 242. The sliding plate 243 approaches the sliding frame 242, and the second hinged rod 244 is deviated under the drive of the sliding frame 242, thereby driving the outer wall contact plate 245 to move in the direction close to the inner liner wall 11.
