Therefore, they should not be construed as limitations on this invention.

[0033] Example 1:

[0034] like Figure 1-10 As shown, the adsorption clamping type production line provided by the present invention includes: a control cabinet, a feeding device 2, a cookware conveying device 4, a discharging device 7, and several clamps 3; the feeding device 2 includes a feeding conveyor line 201, a centering mechanism, a feeding swing mechanism, and a feeding clamping mechanism.

[0035] Each clamp 3 is installed at intervals on the cookware conveying device 4 for negative pressure adsorption onto the bottom of the cookware 1; the centering mechanism is installed on the unloading end of the feeding conveyor line 201 for positioning and centering the cookware 1, and the feeding conveyor motor of the feeding conveyor line 201 is electrically connected to the controller through the feeding conveyor circuit; the clamping drive unit is installed on the feeding swing mechanism, which drives the clamping drive unit to swing horizontally, and the feeding clamping mechanism is used to clamp the cookware 1 at the centering mechanism and release the cookware 1 onto the clamp 3; the cookware conveying device 4 is used to move each clamp 3 and the cookware 1; the unloading device 7 is used to unload the cookware 1 from each clamp 3; a controller is installed in the control cabinet; the feeding device 2, the cookware conveying device 4, the unloading device 7 and several clamps 3 are all driven and controlled by the controller; a button panel 102 and a display screen 101 electrically connected to the controller are installed on the control cabinet.

[0036] The loading device 2 loads the cookware 1 onto each clamp 3. When applied to a non-stick pan production line, the cookware conveying device 4 transports the clamps 3 to the next process, such as painting or drying. Finally, the unloading device 7 unloads the cookware 1, realizing automatic transportation and loading / unloading of the cookware 1 without manual clamping, reducing manual involvement and labor intensity, and is applicable to different non-stick pan processing processes.

[0037] Furthermore, the centering mechanism includes a centering drive unit and two centering inclined rods 207; the centering drive unit includes a centering adjusting tube, a centering adjusting screw, and two centering adjusting seats 205; the centering adjusting tube is fixed parallel to the unloading side edge of the feeding conveyor line 201; a centering elongated hole is provided along the length of the centering adjusting tube facing the feeding side of the feeding conveyor line 201; both centering adjusting seats 205 are slidably installed on the centering adjusting tube and extend out of the centering elongated hole; the centering adjusting screw is coaxially rotatably installed inside the centering adjusting tube, and its two sides are threaded through it. Two centering adjustment seats 205 are inserted; a centering hand-tightening handle 204 with its end fixed to the centering adjustment screw is rotatably installed on one end of the centering adjustment tube; the thread pitch of the centering adjustment screw is the same on both sides, but the rotation direction is opposite; two centering diagonal rods 207 are respectively horizontally fixed on the extended ends of the two centering adjustment seats 205, and the distance between the fixed ends of the two centering diagonal rods 207 is smaller than the distance between the two non-fixed ends; anti-scratch elongated holes are provided along the length direction on the centering diagonal rods 207; multiple anti-scratch rollers 206 with vertical axes are rotatably installed at intervals on the anti-scratch elongated holes.

[0038] The centering mechanism centers the cookware 1 at the unloading end of the feeding conveyor line 201, ensuring that the cookware 1 arriving at the unloading end of the feeding conveyor line 201 is in the same position. The centering adjusting screw, in conjunction with the two centering adjusting seats 205, allows the spacing between the two centering inclined rods 207 to be adjustable according to the diameter of the cookware 1, ensuring that the centers of cookware 1 of different diameters are in the same position, facilitating gripping by the feeding clamping mechanism. Turning the centering hand-tightening handle 204 drives the centering adjusting screw to rotate, causing the opposing threads on both sides of the screw to move the two centering adjusting seats 205 closer or further apart, thus adjusting the position of the two centering inclined rods 207. Anti-scratch rollers 206 block the cookware 1 during the operation of the feeding conveyor line 201, preventing scratches on the surface of the cookware 1.

[0039] Furthermore, the feeding swing mechanism includes a feeding swing base tube 208, a feeding swing drive unit, and a feeding swing rod 209; the feeding swing drive unit includes a swing drive motor 210 and a feeding gear transmission pair; a feeding base plate is provided on the lower end of the feeding swing base tube 208; the lower end of the feeding swing rod 209 is rotatably mounted on the upper end of the feeding swing base tube 208, and a feeding clamping mechanism is mounted on the upper end of the feeding swing rod 209; the swing drive motor 210 drives the feeding swing rod 209 to rotate through the feeding gear drive pair, and is electrically connected to the controller through the swing drive circuit.

[0040] The feeding swing mechanism drives the feeding clamping mechanism to swing horizontally, so that after the feeding clamping mechanism picks up the pot 1, it can move the pot 1 horizontally to above the movement line of the clamp 3. After reaching below the pot 1, the feeding clamping mechanism releases the pot 1, and the feeding swing mechanism drives the feeding clamping mechanism to reset. The swing drive motor 210 drives the feeding swing rod 209 to rotate through the feeding gear transmission pair under the control of the controller, thereby realizing the horizontal swing drive of the feeding clamping mechanism.

[0041] Furthermore, the feeding clamping mechanism includes a feeding horizontal tube 212, a clamping drive unit, and two feeding clamping rods 215; the clamping drive unit includes a clamping drive motor 211 and a clamping drive screw 213; the feeding horizontal tube 212 is horizontally fixed to the upper end of the feeding swing rod 209; a clamping elongated hole 214 is provided along the length direction on the feeding horizontal tube 212; a clamping sliding seat is fixed to one end of each of the two feeding clamping rods 215; the two clamping sliding seats extend into the feeding horizontal tube 212 through the clamping elongated hole 214 and slide along the clamping elongated hole 214; the clamping drive screw 213 is coaxially rotatably installed in the feeding horizontal tube 212, and its two sides are threaded through the two clamping sliding seats respectively; the two sides of the clamping drive screw 213 are threaded The screws have the same pitch but opposite directions of rotation. The clamping drive motor 211 drives the clamping drive screw 213 to rotate and is electrically connected to the controller through the clamping drive circuit. Flexible clamping sleeves 216 are provided on both feeding clamping rods 215. Irregular strips 217 are integrally provided on the opposite side edges of the two flexible clamping sleeves 216. The two irregular strips 217 are used to deform when clamping the pot 1, so that the pot 1 moves upward away from the feeding conveyor line 201. A third position sensor 218, which is electrically connected to the controller, is provided on the opposite side of the feeding horizontal tube 212 and the clamping elongated hole 214. When the third position sensor 218 detects that the clamp 3 has passed by, the controller controls the feeding clamping mechanism to release the pot 1 so that the clamp 3 can clamp the bottom center of the pot 1.

[0042] The clamping drive motor 211, under the control of the controller, drives the clamping drive screw 213 to rotate, causing the two clamping sliding seats to move the two feeding clamping rods 215 closer or further apart, thereby clamping or releasing the cookware 1. The flexible clamping sleeve 216 prevents the surface of the cookware 1 from being scratched due to clamping, and at the same time plays a role in stabilizing the grip and preventing slippage, thus improving the clamping stability. The deformation generated by the irregular strip 217 realizes a small up-and-down drive of the cookware 1, so that the cookware 1 can move upward and get away from the feeding conveyor line 201, and can swing without being disturbed by the centering mechanism.

[0051] The vent 309 connects the negative pressure pipe 306 and the clamp support pipe 301, allowing the negative pressure air pump 317 to simultaneously draw air from both pipes. When the bottom of the cookware 1 is completely covered and adheres to the adsorption sealing ring 304, it is adsorbed by negative pressure, thus gripping the cookware 1. The adsorption sealing ring also provides cushioning, preventing damage from contact between the cookware 1 and the clamping plate 302. The installation method and position of the release rod 305 allow it to be pushed upwards at its lower end, causing the upper end to lift the cookware 1, releasing it from the adsorption sealing ring 304. The positioning cantilever 319 facilitates the placement of the clamp 3... Installed on the production line, the fixture support tube 301 is installed in a way that allows the pot 1 to rotate; the bullseye wheel 316 reduces the friction at the lower end of the release rod 305 to prevent wear, allowing the release rod 305 to move upward stably; the cooperation between the piston 314, the sliding ring groove 312 and the fixture return spring 313 allows the release rod 305 to move downward and return to its original position after the fixture 3 releases the pot 1, and ensures that the upper end of the release rod 305 is always within the adsorption groove 303 when the fixture 3 adsorbs and holds the pot 1; the sliding contact line 326 and the current collector provide mobile power to the negative pressure air pump 317, ensuring that the negative pressure air pump 317 is always in working condition and ensuring the negative pressure adsorption effect at the top of the clamping unit.
