[0002] In the cookware manufacturing industry, the welding and assembly of cookware handles is a crucial process for ensuring product structural reliability, directly affecting the safety and lifespan of the cookware. Currently, cookware handle welding is generally carried out using semi-automated equipment assisted by manual labor, which has many shortcomings in actual production: Firstly, the connection between various processes such as adjusting the posture of the cookware, aligning the handle, welding, and post-weld processing relies on manual operation, which results in high labor intensity for workers, slow production pace, and difficulty in achieving large-scale continuous production. Secondly, the handle docking mechanism has limited adjustment freedom, making it difficult to accurately match the welding position and angle of the cookware's outer wall, and the fitting accuracy is difficult to guarantee; at the same time, the laser welding head cannot operate continuously along the weld seam in the circumferential direction, resulting in poor weld seam uniformity and consistency, and unstable product yield. Third, welding fume purification and post-weld cooling are mostly independent external devices, welding exhaust gas cannot be collected and purified in time, the working environment is poor, natural cooling after welding takes a long time, and switching between single-handle and double-handle products requires repeated clamping, resulting in insufficient production flexibility.

A cookware positioning mechanism 2 and a handle docking mechanism 3 are installed on the top of the body 1. An auxiliary mechanism 4 is arranged at the discharge end of the first feeder 101. The cookware positioning mechanism 2 and the auxiliary mechanism 4 cooperate to turn the cookware into an inverted state and transfer it to the top of the middle of the body 1. The handle docking mechanism 3 is used to attach the handle to the outer wall of the cookware. A welding mechanism 5 and a multi-functional mechanism 6 are installed on the back of the body 1. The multi-functional mechanism 6 purifies the gas generated at the welding point of the cookware and handle and air-cools the welding point.

[0020] Example 2

[0021] Please refer to Figure 3 As shown, the cookware positioning mechanism 2 includes a first motor 201 and a rotating rod 203. The first motor 201 is fixedly installed on the top wall of the machine body 1. The rotating rod 203 is rotatably connected to the middle of the top of the machine body 1. A first driven gear 204 is fixedly connected to the outer wall of the rotating rod 203. A first drive gear 202 that meshes with the first driven gear 204 is fixedly installed at the output end of the first motor 201. A first linear drive rail 205 is fixedly connected to the top of the rotating rod 203.

[0022] Please refer to Figure 4 As shown, the first linear drive rail 205 is used to drive the first moving plate 206 to reciprocate along its top wall. The top of the first moving plate 206 is fixedly mounted with a second motor 207. The output end of the second motor 207 is fixedly mounted with a second drive gear 208. The top of the first moving plate 206 is also rotatably connected with a first electric push rod 209. The outer wall of the first electric push rod 209 is fixedly mounted with a second driven gear 210. The second drive gear 208 meshes with the second driven gear 210. The output end of the first electric push rod 209 is fixedly connected with a second linear drive rail 211. The second linear drive rail 211 is used to drive the two sets of second moving plates 212 to move closer or further apart. The outer wall of the second moving plate 212 is provided with a third motor 213. The output end of the third motor 213 is fixedly connected to the first clamping member 214.

[0023] Those skilled in the art will understand that by driving the output end of the first motor 201 to rotate, the first drive gear 202 rotates, which in turn drives the first driven gear 204 and the rotating rod 203 to rotate as a whole, thereby causing the first linear drive rail 205, the first moving plate 206, the second linear drive rail 211 and the two sets of first clamping members 214 located at the top of the rotating rod 203 to rotate as a whole around the center of the rotating rod 203; By driving the first linear drive rail 205 to work, the first moving plate 206 can reciprocate along the top wall of the first linear drive rail 205, thereby driving the second linear drive rail 211 and the two sets of first clamping members 214 to move along with the first moving plate 206. Furthermore, by driving the output end of the second motor 207 to drive the second drive gear 208 to rotate, the second driven gear 210 and the first electric push rod 209 rotate as a whole, thereby driving the second linear drive rail 211 and the two sets of first clamping members 214 to rotate as a whole, so that the two sets of first clamping members 214 can be kept in the left and right sides or in the front and back sides respectively; by driving the output end of the first electric push rod 209 to extend or retract, the second linear drive rail 211 and the two sets of first clamping members 214 can be driven to move upward or downward as a whole; In addition, in this embodiment, the two sets of first clamping members 214 can be used to clamp the inner walls of the pot in an internal support manner or to clamp the outer walls of the pot in an external clamp manner. The two sets of first clamping members 214 are driven to rotate by the output ends of the two sets of third motors 213 respectively, and the tilt angle of the first clamping members 214 is adjusted. Since the tilt angle of the straight line connecting the top edge point and the corresponding bottom edge point of the pot is different for different sizes of pots, this method can be well applied to clamping pots of different sizes in an internal support manner or in an external clamp manner.

[0024] Example 3

[0025] Please refer to Figure 10 As shown, the auxiliary mechanism 4 includes a third electric push rod 402. Support plates 401 are welded to both sides of the discharge end of the first feeder 101. The third electric push rod 402 is provided with two sets of support plates 401 that are rotatably connected to the two sets of support plates 401 respectively. A third clamping member 403 is fixedly installed at the output end of the third electric push rod 402. A fourth driven gear 404 is fixedly connected to the outer wall of one set of third electric push rods 402. A drive motor is provided on the outer wall of one set of support plates 401. A fifth drive gear 405 is fixedly installed at the output end of the drive motor. The fifth drive gear 405 meshes with the fourth driven gear 404.

[0026] Those skilled in the art will understand that by driving the output ends of the two sets of third electric push rods 402 to extend or retract synchronously, the two sets of third clamping members 403 are driven to move closer or further apart; and when the two sets of third clamping members 403 move closer together, they clamp the two sides of the outer wall of the pot. By driving the output end of the drive motor to rotate, the fifth drive gear 405 is rotated, thereby driving the pot in the clamped state to flip over.

[0027] Example 4

[0028] Please refer to Figure 3 and Figure 5 As shown, the handle docking mechanism 3 includes a fourth motor 301 and a first rotating gear ring 303. The fourth motor 301 is fixedly installed on the back of the body 1. The output end of the fourth motor 301 is fixedly connected to the third drive gear 302. The first rotating gear ring 303 is rotatably connected to the top of the body 1. The third drive gear 302 meshes with the first rotating gear ring 303. A third linear drive rail 304 is fixedly connected to the top of the first rotating gear ring 303. The third linear drive rail 304 is used to drive the third moving plate 305 to reciprocate along its top wall.

[0029] Please refer to Figure 5 As shown, a second electric push rod 308 is rotatably connected to the top of the third moving plate 305. The output end of the second electric push rod 308 is fixedly connected to the mounting plate 310. A third driven gear 309 is fixedly installed on the outer wall of the second electric push rod 308. A fifth motor 306 is fixedly connected to the top of the third moving plate 305. A fourth drive gear 307 that meshes with the third driven gear 309 is fixedly connected to the output end of the fifth motor 306. A sixth motor 311 is provided on the bottom wall of the mounting plate 310. The output end of the sixth motor 311 passes through the bottom wall of the mounting plate 310 and is fixedly connected to the mounting frame 312. A rotating component 313 is rotatably connected inside the mounting frame 312. A seventh motor 314 that drives the rotating component 313 to rotate is provided on the outer wall of the mounting frame 312. A dual-shaft cylinder 315 is fixedly installed on the outer end of the rotating component 313. A second clamping component 316 is fixedly connected to both output ends of the dual-shaft cylinder 315.

[0030] Those skilled in the art will understand that by driving the output of the fourth motor 301 to drive the third drive gear 302 to rotate, the first rotating gear ring 303 rotates on the top of the machine body 1, causing the third linear drive rail 304, mounting plate 310, mounting frame 312 and the two sets of second clamping members 316 to rotate as a whole around the center of the first rotating gear ring 303 (the center of the rotating rod 203). It is worth noting here that the height of the third linear drive rail 304 is lower than the height of the first linear drive rail 205, and the two will not interfere with each other when they both rotate around the center of the rotating rod 203. The output of the fifth motor 306 drives the fourth drive gear 307 to rotate, causing the third driven gear 309 and the second electric push rod 308 to rotate as a whole. This causes the mounting plate 310, mounting frame 312, and the two sets of second clamping members 316 to rotate around the center of the third driven gear 309. Furthermore, by extending or retracting the output of the second electric push rod 308, the mounting plate 310, mounting frame 312, and the two sets of second clamping members 316 can be moved upward or downward as a whole. Furthermore, by rotating the output end of the sixth motor 311, the mounting frame 312 and the two sets of second clamping members 316 are rotated as a whole, which can keep the two sets of second clamping members 316 in a state on the left and right sides or in a state on the front and back sides respectively; and by rotating the output end of the seventh motor 314, the rotating member 313, the dual-axis cylinder 315 and the two sets of second clamping members 316 are rotated, which changes the tilt angle of the two sets of second clamping members 316; and by driving the two output ends of the dual-axis cylinder 315 to extend or retract synchronously, the two sets of second clamping members 316 are moved away from or closer to each other.

[0031] Example 6

A seventh drive gear 512 that meshes with the second rotating gear ring 513 is fixedly connected to the output end of the ninth motor 511.

[0034] Those skilled in the art will understand that by driving the fourth linear drive rail 502 to work, the fourth moving plate 503 is made to move horizontally back and forth, thereby enabling the fourth electric push rod 504, the lifting plate 505, the mounting block 510, the second rotating gear ring 513, the laser welding head 514, and the multi-functional mechanism 6 to move horizontally back and forth as a whole; by driving the output end of the fourth electric push rod 504 to extend or retract, the lifting plate 505, the mounting block 510, the second rotating gear ring 513, the laser welding head 514, and the multi-functional mechanism 6 to move upward or downward as a whole; Furthermore, by extending or retracting the output end of the fifth electric push rod 508, the mounting block 510, the second rotating gear ring 513, and the laser welding head 514 are moved forward or backward as a whole.

In addition, by driving the output end of the ninth motor 511 to rotate, the seventh drive gear 512 is rotated, thereby driving the second rotating gear ring 513 and the laser welding head 514 to rotate around the mounting block 510. A limit groove and a limit slider structure are provided between the second rotating gear ring 513 and the mounting block 510, which improves the stability of the second rotating gear ring 513 rotating within the mounting block 510.

[0038] Those skilled in the art will understand that by extending or retracting the output end of the sixth electric push rod 602, the lifting block 603, the seventh electric push rod 606, and the nozzle 608 can move downward or upward as a whole; by driving the output end of the tenth motor 604 to rotate the eighth drive gear 605, the sixth driven gear 607, the seventh electric push rod 606, and the nozzle 608 can rotate as a whole, thus changing the tilt angle of the nozzle 608; Furthermore, by starting the purifier 609, the nozzle 608 is drawn in air. When the air pump 610 and the cooler 611 are started, the external air source is cooled by the cooler 611 and then delivered to the nozzle 608 for spraying.

[0039] The working principle of this device is as follows: S1. The first feeder 101 has two sets of conveyor belts with a gap between them. The first feeder 101 conveys the pot to the position behind it and determines whether the pot is upside down. The upside-down state is when the opening of the pot is facing down. If the pot is inverted, the output of the first motor 201 is rotated, causing the first linear drive rail 205 to rotate toward the first feeder 101. Then, the output of the second motor 207 is rotated, keeping the two sets of first clamping members 214 positioned on the front and rear sides respectively. Next, the first linear drive rail 205 operates, driving the second linear drive rail 211 and the two sets of first clamping members 214 to move directly beneath the pot. Finally, the outputs of the two third motors 213 are driven to rotate, moving the first clamping members 214... The tilt angle of 14 is adjusted to match the tilt angle of the inner wall of the pot. Then, the output end of the first electric push rod 209 is extended, which drives the second linear drive rail 211 and the two sets of first clamping members 214 to move upward as a whole. The two sets of first clamping members 214 enter the pot. Then, by driving the second linear drive rail 211, the two sets of first clamping members 214 are moved away from each other and clamp and fix the two sides of the inner wall of the pot. Finally, driven by the first linear drive rail 205, the clamped pot is moved to the top center of the machine body 1. If the cookware is not in an inverted position, adjust the tilt angle of the two sets of first clamping members 214 to match the tilt angle of the outer wall of the cookware. Use the two sets of first clamping members 214 to clamp the two sides of the outer wall of the cookware. Then, extend the output end of the first electric push rod 209 to move the cookware in the external clamping state upward, so that the top of the cookware is between the two sets of third clamping members 403. Simultaneously extend the output ends of the two sets of third electric push rods 402, so that the two sets of third clamping members 403 move closer to each other and support the top of the cookware. The two sides of the pot are clamped and fixed. The two sets of first clamping members 214 are reset to the bottom of the first feeder 101, and the output end of the drive motor is driven to rotate, so that the fifth drive gear 405 rotates and drives the pot in the clamped state to flip so that the opening of the pot faces down. The above operation is repeated, and the two sets of third clamping members 403 are still used to clamp the inner wall of the pot in an internal support manner. Finally, under the drive of the first linear drive rail 205, the clamped pot is also driven to the top center of the machine body 1. S2. The second feeder 102 also has two sets of conveyor belts with a gap between them. The two sets of conveyor belts transport the longitudinally placed handles. When the second feeder 102 transports the handles to its right side, the output of the fourth motor 301 drives the third drive gear 302 to rotate, causing the third linear drive rail 304 to rotate to a position facing the second feeder 102. Then, the output of the fifth motor 306 drives the fourth drive gear 307 to rotate, causing the mounting plate 310, mounting frame 312, and two sets of second clamping members 316 to also face the second feeder 102. The feeder 102 then starts working by activating the third linear drive rail 304, so that the two sets of second clamping members 316 are located directly below the handle. Then, the output end of the sixth motor 311 is driven to rotate, so that the two sets of second clamping members 316 are kept on the left and right sides respectively. Then, the output end of the second electric push rod 308 is driven to extend, causing the two sets of second clamping members 316 to move upward and be located on the left and right sides of the handle respectively. Then, the two output ends of the dual-axis cylinder 315 are driven to retract synchronously, so that the two sets of second clamping members 316 are brought closer to each other and clamped and fixed to the handle. S3. By driving the output of the first motor 201 to rotate, the clamped pot rotates, causing the handle to be connected to be positioned on the right side of the pot. Simultaneously, under the action of the output of the fourth motor 301, the clamped handle also rotates to the right side of the pot. The output of the sixth motor 311 is driven to rotate, causing the clamped handle to rotate again and align the welding end of the handle with the pot. Then, the output of the seventh motor 314 is driven to rotate, causing the clamped handle to tilt. The output of the second electric push rod 308 is driven to extend or retract, so that the height of the welding end of the handle matches the height of the handle to be connected to the pot. Finally, the third linear drive rail 304 is driven to move the clamped handle toward the pot and align it with the position of the handle to be connected to the pot. S4. Under the combined action of the fourth linear drive rail 502, the output end of the fourth electric actuator 504, the output end of the eighth motor 506, and the output end of the fifth electric actuator 508, the mounting block 510 is kept in a certain tilted state, and the welding position of the handle is located inside the second rotating gear ring 513. Then, under the combined action of the output end of the sixth electric actuator 602, the output end of the tenth motor 604, and the seventh electric actuator 606, the nozzle 608 is adjusted to a tilted state and aligned with the welding position of the handle. This is achieved by driving the ninth electric actuator... The output end of the machine 511 rotates, causing the laser welding head 514 to rotate around the mounting block 510. The laser emitted by the laser welding head 514 welds the handle and the pot at the contact point. During welding, the purifier 609 is activated, causing the nozzle 608 to draw in and purify the gas generated during welding. After welding is completed, the air pump 610 and the cooler 611 are activated. The external air source is cooled by the cooler 611 and then delivered to the nozzle 608 for air cooling of the welded area. The device in this invention can not only perform the welding of single-handle cookware as described above, but also weld a handle to the other side of the outer wall of the cookware to form a double-handle cookware. This can be achieved by rotating the cookware under the action of the output end of the first motor 201, adjusting the position of the handle to be connected on the other side of the cookware to be located on the right side of the cookware, and repeating the above operation to weld the other handle. The entire process is automated, convenient and fast.

Both of these are existing technologies and will not be elaborated on in this invention.
