Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electromagnetic oven heating ring production, in particular to a welding equipment for electromagnetic oven switching heating ring. BACKGROUND

[0002] The electromagnetic oven, also known as the electromagnetic stove, is a product of modern kitchen revolution. It produces heat directly on the bottom of the pot without fire or conduction heating, so the thermal efficiency is greatly improved. It is a kind of high-efficiency energy-saving kitchen utensil, which is completely different from all traditional fire or non-fire conduction heating kitchen utensils.

[0003] The heating ring of the electromagnetic oven is usually composed of pure copper, aluminum-coated copper or pure aluminum, and is in a ring shape. During processing, it usually needs to be bent, and then the two ends of the bent ring pipe are welded together to form an integrated structure. For example, the welding equipment for electromagnetic oven switching heating ring disclosed in Chinese patent (CN218362858U) records this content. In the traditional technology, manual bending is adopted, which is time-consuming and laborious. Later, the bending is performed through a device, but the two ends of the bent ring pipe often do not have the same height, which leads to the subsequent inability to weld, and still needs to be adjusted by the staff. In addition, the heating ring formed after welding is not a perfect ring shape, and there is a "deformation", which is difficult to meet the needs of the staff. SUMMARY

[0066] Those skilled in the art will understand that the fourth lead screw 802 is driven to rotate by the output end of the fourth stepper motor 804, causing the third movable plate 805 to move closer to or further away from the center of the rotating table 105, thereby causing the housing 806 to move closer to or further away from the center of the rotating table 105; and the movable block 811 is driven to move by the output end of the second cylinder 810, causing the first connecting rod 812, the second connecting rod 813, and the half gear 814 to rotate in a coordinated manner, causing the two sets of racks 809 to move closer to or further away from each other, thereby causing the two sets of clamping plates 808 to move closer to or further away from each other; and the drive gear 107 is driven to rotate by the output end of the motor 106, causing the driven gear 108 to rotate, thereby causing the rotating table 105, the spreading mechanism 3, the clamping mechanism 4, the bending mechanism 5, and the welding mechanism 7 to rotate as a whole.

[0067] To describe the working principle of the present invention in detail, we will use... Figure 1 To illustrate from this perspective, the specific steps are as follows:

[0068] S1. The first robotic arm 102 transports the external copper rod material to the space between the front and rear guide wheels 103. The guide wheels 103 rotate, driving the copper rod material to move to the right. The length of the copper rod material extending beyond the right side of the table 101 is controlled according to the production circumference of the heating ring of the induction cooker. The second robotic arm 104 clamps the right end of the copper rod material. Then, it controls the extension of the output end of the first cylinder 204, driving the cutting blade 205 to approach the copper rod material. At the same time, the first drive motor 201 is started, causing the drive gear 202 to rotate, driving the driven gear 203 to rotate. The center of the copper rod material and the center of the driven gear 203 are concentric, so the cutting blade 205 rotates around the center of the copper rod material to achieve cutting.

[0069] S2. The second robotic arm 104 transports the cut copper rod material to the inside of the fixed plate 401. It is worth noting that the middle part of the copper rod material is located inside the fixed plate 401. The output end of the second drive motor 409 drives the first gear 405 to rotate, so that the outer gear 404, the rotating ring 402 and the inner gear 403 rotate as a whole. Then, several sets of second gears 406 rotate synchronously, driving all the clamping parts 407 to move synchronously towards the center of the fixed plate 401 to clamp the outer wall of the middle part of the copper rod material. At this time, the copper rod material is in a horizontal state.

[0070] S3. Adjust the position of the expansion slot 304 according to the production circumference of the heating ring of the induction cooker. Drive the second bevel gear 306 to rotate through the output end of the first stepper motor 307, so that the six sets of first bevel gears 305 and the first lead screw 301 rotate synchronously as a whole, and drive the six sets of first movable plates 303 to move synchronously towards or away from the center position of the rotating table 105, so that the circumference of the "circle" formed by connecting the position points of all the expansion slots 304 is adapted to the production circumference of the heating ring of the induction cooker.

[0071] S4. The output end of the first electric push rod 511 extends, causing the clamping member 512 to move downward, so that the height of the clamping member 512 matches the height of the copper rod material. The output end of the second stepper motor 509 drives the second lead screw 507 to rotate, causing the movable member 510 to move closer to the center of the rotating table 105, thereby causing the clamping member 512 to move closer to the center of the rotating table 105. The copper rod material is located inside the clamping member 512. Then, the output end of the third drive motor 501 rotates counterclockwise, and the output end of the fourth drive motor 504 rotates clockwise, so that the two sets of clamping members 512 rotate from both sides of the first movable plate 303 with clamping mechanism 4 respectively. The copper rod material moves to both sides of the first movable plate 303 with welding mechanism 7. During the rotation, the surface of the copper rod material abuts against the inner wall of the expansion groove 304. It is worth noting that the two ends of the copper rod material are in a "raised" state because they are not subjected to the abutment force, which makes welding impossible. Then, the output end of the third stepper motor 604 drives the third lead screw 602 to rotate, causing the second movable plate 605 to move towards the center of the rotating table 105, which in turn drives the pressure head 606 to move towards the center of the rotating table 105. The pressure head 606 presses down on the two ends of the copper rod material and abuts against the inner wall of the expansion groove 304 on the first movable plate 303 with welding mechanism 7.

[0072] S5. The output end of the drive motor 704 drives one set of drive gears 702 to rotate, causing the rotating gear ring 701 and another set of drive gears 702 to rotate, thereby realizing the continuous rotation of the welding head 703 and welding the two ends of the copper rod material together.

[0073] S6. It is worth mentioning that the heating ring of the induction cooker formed at this time is not a perfect ring shape. Therefore, the present invention is adapted to provide a calibration mechanism 8. The output ends of the two sets of fourth stepper motors 804 synchronously drive the two sets of fourth lead screws 802 to rotate, so that the two sets of housings 806 move synchronously towards the center position of the rotating table 105. The output end of the second cylinder 810 drives the movable block 811 to move, so that the first connecting rod 812, the second connecting rod 813 and the half gear 814 rotate in linkage. This drives the two sets of clamping plates 808 located in the same set of housings 806 to move closer to each other, clamping and fixing the surface of the welded copper rod raw material. Rubber pads are installed on the inner side of the clamping plates 808 to increase the clamping force. Friction forces cause the clamping mechanism 4 to release the copper rod material from its gripping position. The output of the motor 106 drives the drive gear 107 to rotate, causing the driven gear 108 to rotate. This causes the rotating table 105 and all the first movable plates 303 to rotate synchronously. The inner wall of the spreading groove 304 abuts against the outer wall of the copper rod material, so that the outer wall of the fixed copper rod material forms a complete ring under the action of the spreading groove 304. Finally, the second robotic arm 104 clamps the ring-shaped induction furnace heating ring, and all the first movable plates 303 move towards the center of the rotating table 105. The second robotic arm 104 can then remove the ring, which is convenient, fast, and fully automated, meeting the needs of the workers.
