Detailed Implementation

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Example 1

[0026] An automatic feeding device for welding sheets on the heating plate of an electric rice cooker, such as Figure 1-4 As shown, the system includes a loading assembly, which includes a workbench 1. A second rotary motor 27 is bolted to the top outer wall of the workbench 1. A second rotary shaft 28 is connected to the top of the second rotary motor 27. A mounting frame 9 is mounted on the top of the second rotary shaft 28. An electric telescopic rod 10 is bolted to one side outer wall of the mounting frame 9. The output end of the electric telescopic rod 10 can slide through the mounting frame 9. A fixing frame 7 is mounted at the end of the electric telescopic rod 10. An electric lifting rod 8 is bolted to the top outer wall of the fixing frame 7. The output end of the electric lifting rod 8 can slide through the fixing frame 7. A connecting frame 22 is mounted at the bottom of the electric lifting rod 8. Multiple sets of vacuum pumps 6 are mounted on the top of the connecting frame 22. Multiple sets of suction cups 21 are mounted at the bottom of the connecting frame 22. Each set of suction cups 21 is connected to a corresponding vacuum pump 6. A feeding assembly for conveying welding sheets and a conveying assembly for conveying heating plates are provided on one side of the workbench 1.

[0027] In use, the second rotating motor 27 controls the rotation of the second rotating shaft 28, which in turn controls the rotation of the mounting bracket 9 to adjust the direction of the suction cup 21. The electric telescopic rod 10 can adjust the position of the suction cup 21, and the electric lifting rod 8 can adjust the height of the suction cup 21. By adjusting these parameters, the suction cup 21 can be moved to the feeding assembly to contact the stacked welding pieces. The vacuum pump 6 removes the air from the suction cup 21, causing it to hold the welding pieces and move. After holding the welding pieces, the position, direction, and height of the suction cup 21 are adjusted to move it to the heating plate on the conveying assembly. Once the welding pieces are moved to the welding point and contact the suction cup 21 to fix them, the welding pieces are accurately loaded, thereby effectively increasing the welding efficiency.

[0028] The feeding assembly includes a first rotary motor 24, which is fixed to the top outer wall of the workbench 1 by bolts. A first rotary shaft 23 is connected to the top of the first rotary motor 24, and a rotary disk 4 is installed on the top of the first rotary shaft 23. Multiple stacking racks 5 are installed on the top of the rotary disk 4.

[0029] In use, the welding sheets can be stacked and placed in multiple stacking racks 5. The suction cup 21 can be moved to the stacking rack 5 to grab the placed welding sheets. The first rotating shaft 23 and the rotating disk 4 can be rotated by the first rotating motor 24 to switch between different stacking racks 5 for feeding, so that the feeding can be cyclical, which is convenient for replenishing welding sheets and avoids affecting the gripping of welding sheets when replenishing.

[0030] The conveying assembly includes a support frame 13, which has two sets and is fixed to the top outer wall of the workbench 1 by bolts. A drive motor 14 is installed on one side of the support frame 13. There are two sets of drive motors 14. One end of the drive motor 14 is connected to a transmission shaft 25. One end of the transmission shaft 25 is rotatably inserted through the support frame 13. A pulley 26 is installed on one end of the transmission shaft 25. A conveyor belt 12 is installed through the pulley 26. A driven wheel is rotatably installed on one side of the support frame 13. The driven wheel is adapted to the conveyor belt 12.

[0031] In use, the driven wheel is located in the center of the conveyor belt 12. The drive motor 14 starts and controls the drive shaft 25 to rotate. The drive shaft 25 controls the pulley 26 to rotate, which drives the conveyor belt 12. The rotating conveyor belt 12 can place the heating plate for conveying and transporting it to a suitable position for loading welding pieces. The conveying operation can be carried out in a cycle, thereby increasing the processing efficiency. The driven wheel can support the conveyor belt 12 to prevent it from collapsing in the center during conveying.

[0032] To support the device, such as Figure 2 , 4 As shown, two sets of support legs 15 are fixed to the bottom outer wall of the workbench 1 by bolts, and foot pads 16 are installed at the bottom of the support legs 15.

[0033] During use, the device can be supported by the support legs 15 and the foot pads 16, thereby maintaining the stability of the device;

[0034] To secure the heating plate during the loading of solder pads, such as Figure 1 , 3 As shown, a fixing block 19 is fixedly installed on the top outer wall of the support frame 13 by bolts. There are two sets of fixing blocks 19. An electric push rod 11 is installed on one side of the fixing block 19. The output end of the electric push rod 11 can slide through the fixing block 19. A clamping frame 20 is installed on one end of the electric push rod 11. A protective pad is installed on one side of the clamping frame 20. The protective pad is made of rubber.

[0035] In use, the two sets of fixing blocks 19 are symmetrically installed on the two sets of support frames 13. The movement of the clamping frame 20 can be controlled by the electric push rod 11. The clamping frame 20 can be moved to clamp and fix the heating plate when it is transported to the filling position and the transport stops, so as to facilitate the filling of the welding sheet. The rubber protective pad can prevent the heating plate from slipping while clamping it and can also play a buffering and protective role.

[0036] For ease of observation after welding, such as Figure 1 As shown, a lamp holder 2 is fixed to the top outer wall of the workbench 1 by bolts, and a lighting lamp 3 is installed on one side of the lamp holder 2;

[0037] When in use, the lighting lamp 3 can be turned on to provide illumination, which makes it easy to observe the completed heating plate and check for any defects.

[0038] To prevent the device from sliding, such as Figure 4 As shown, a pad 17 is provided at the bottom of the foot pad 16. The pad 17 is made of rubber and has annular patterns at the bottom.

[0039] When in use, the rubber pad 17, in conjunction with the annular pattern on its bottom, increases the friction when in contact with the ground, thereby increasing anti-slip properties and preventing the device from sliding or shifting.
