[0045] refer to Figures 1-14 This embodiment provides an automatic processing production line for cylindrical can bodies, wherein a storage device 1, a loading device 2, a conveying device 3, a rolling device 4, and a discharging device 5 are sequentially arranged along the transportation route of the sheet metal part 11. At least one cutting device is arranged on the conveying route of the conveying device 3, and a clamp assembly 8, a welding device 9, and a visual inspection device 10 are arranged at the rolling device 4 to cooperate with the rolling device 4, thereby realizing a series of functions from material storage, transportation, caching, secondary shearing, rolling welding inspection, etc.

[0046] refer to Figure 3 The material storage device 1 provided in this embodiment includes a material rack 101 and a material retrieving trolley 104. The material rack 101 adopts a stereoscopic warehouse structure, and is stored in the form of plate stacks through the stereoscopic warehouse. The stereoscopic warehouse is composed of square tube columns, pallets 102, and five layers of goods through angle steel connectors and screws. The material retrieving trolley 104 is composed of an automatic material retrieving machine 105 and an AGV trolley 106.

[0047] refer to Figure 4 The automatic material reclaimer 105 is provided with a material reclaiming fork 107. The material rack 101 is provided with five layers of pallets 102. The material reclaiming fork 107 can be lifted up and down and extended forward and backward under the drive of the automatic material reclaimer 105. The sheet metal part 11 is a plate. In order to facilitate the material reclaiming fork 107 to obtain the sheet metal part 11 on the pallet 102, the pallet 102 is bent downward and provided with two first long grooves 103. The first long grooves 103 are used to make way for the material reclaiming fork 107. When reclaiming, the material reclaiming fork 107 extends into the first long groove 103, and after lifting the sheet metal part 11 upward to separate from the pallet 102, the material reclaiming fork 107 withdraws from the first long groove 103 and is transported to the loading device 2 by the AGV trolley 106 for loading.

[0048] refer to Figure 2 The feeding device 2 provided in this embodiment includes a material storage platform 201, a vacuum adsorption fixture 203 and a three-axis driving device 204. The material storage platform 201 is arranged below the vacuum adsorption fixture 203, and a conveying device 3 is arranged on one side of the material storage platform 201. Figure 5, the three-axis drive device 204 includes an X-axis translation 205, a Y-axis translation 206, a Z-axis translation 207, and a rotating base 208 mounted on a fixed base in the Y-axis direction. The rotating base 208 is used to mount a vacuum adsorption fixture 203. The vacuum adsorption fixture 203 can rotate circumferentially under the action of the rotating base 208. The vacuum adsorption fixture 203 is driven by the three-axis drive device 204 to obtain the sheet metal part 11 on the storage table 201 and transport it to the conveying device 3.

[0049] The structure of the tray 102 for storing the sheet metal part 11 on the storage table 201 is the same as that of the tray 102 of the rack 101. It is also provided with a second long slot 202 for the feeding movement of the feeding fork 107 to make way. At the same time, a positioning and guiding sheet metal is added to the tray 102 structure of the storage table 201 for positioning the sheet metal part 11.

[0050] The vacuum adsorption fixture 203 has a number of suction cups. The suction cups are used to suck the sheet metal part 11 placed on the storage table 201 and perform the feeding process to the conveying device 3 through the three-axis drive device 204. In the three-axis drive device 204, the movement direction of the X-axis uses a helical gear and rack module, the movement of the Y-axis adopts a movement mechanism of a lead screw module, and the movement of the Z-axis is driven by a lead screw module to perform a linear motion. Since the picking trolley 104 picks up materials from the rack 101 and places them on the storage table 201, it is impossible to ensure whether there will be a slight deviation of the sheet metal part 11. Therefore, the design method is to add a servo motor in the Y-axis direction to drive the rotating base 208 to rotate. The motor can rotate a specific angle through the compilation of the encoder, which is used to correct the deviation error generated by the sheet metal part 11 and ensure the position accuracy of feeding to the conveying device 3.

[0051] Reference Figures 6-7 , the conveying device 3 provided in this embodiment includes a first conveyor belt 301, a second conveyor belt 302, and a third conveyor belt 303. A third conveyor belt 303 is provided between the first conveyor belt 301 and the second conveyor belt 302. The first conveyor belt 301 is connected to the feeding device 2, the second conveyor belt 302 is connected to the curling device 4. A first cutting device 6 is provided at the connection of the first conveyor belt 301 and the third conveyor belt 303, and a second cutting device 7 is provided at the connection of the third conveyor belt 303 and the second conveyor belt 302. The first cutting device 6 performs a horizontal cutting, and the second cutting device 7 performs a vertical cutting. Through secondary cutting, it is ensured that the sheet metal reaches the final size before the can body is curled, and then curling is performed.

[0052] The first conveyor belt 301 is used to transport the sheet metal parts 11 to be cut. The transport area of its conveyor belt should be larger than that of the second conveyor belt 302 and the third conveyor belt 303. The large conveyor belt is responsible for the transverse shearing of the sheet material. After shearing, the sheet material is transported to the small conveyor belt by the conveyor belt for longitudinal shearing to obtain the final size. In terms of design, the first conveyor belt 301 is composed of two sets of belt conveyor belts spliced together. The first conveyor belt 301 can be installed more easily by using two racks and two drums for splicing. And a speed control motor and sensors are arranged on the first conveyor belt 301; several sensors are distributed at intervals on the transmission route of the first conveyor belt 301. By using the sensors to identify the position and adding the adjustment of the speed of the first conveyor belt 301 by the speed control motor, the shearing position of the guillotine shear can be accurately positioned.

[0053] Since the position of the sheet metal parts 11 may shift when they fall onto the second conveyor belt 302 and the third conveyor belt 303 after cutting, drainage channels 304 are provided on both the second conveyor belt 302 and the third conveyor belt 303. Refer to Figure 8 , the drainage channel 304 is composed of two opposite partitions. The width of the drainage channel 304 gradually decreases along the transport direction. The inlet of the drainage channel 304 forms a flared opening, and the width at the outlet of the drainage channel 304 is adapted to the cutting width of the sheet metal parts 11, so as to adjust the position of the sheet metal parts 11 on the conveyor belt to the correct position and realize the correct positioning for entering the next link.

[0054] During the process of the third conveyor belt 303 feeding the sheet metal parts 11 to the second cutting device 7 and the second conveyor belt 302 feeding the sheet metal parts 11 to the curling device 4, after the sheet metal parts 11 leave the belt by half of the distance on the small conveyor belt, it is easy to fall due to the center of gravity being outside. By adding a clamping device 305 on the existing conveyor belt, the clamping function can be realized, so that the sheet metal parts 11 can enter the second cutting device 7 or the curling device 4 smoothly at the correct position when entering.

[0055] The clamping device 305 includes a first roller 306 and a second roller 307; the first roller 306 is a driving roller at the end of the conveyor belt, and the second roller 307 is vertically arranged above the first roller 306 by a drum, which can realize the clamping function.

[0056] The first cutting device 6 and the second cutting device 7 provided in this embodiment are both guillotine shears. The guillotine shear includes a clamping mechanism and a cutting tool. The cutting tool is composed of three sections of blades. The clamping mechanism is used to clamp and fix the workpiece to be sheared. The tool of the guillotine shear is composed of three small sections. If it becomes dull after a long time, the dull part can be replaced, which is convenient for setting and maintenance.

[0057] Refer to Figure 11, the curling device 4 provided in this embodiment is a plate rolling machine for bending the sheet metal part 11. The power source of the plate rolling machine is a three-phase asynchronous motor connected to a worm and worm gear reducer to provide powerful power. The sheet metal part 11 transported by the conveyor belt is clamped by the upper roller and the lower roller and curled into the desired curvature by the side roller.

[0058] Reference Figure 11 , in this embodiment, a welding device 9 and a vision detection device 10 are added on the basis of the plate rolling machine. Reference Figure 12 , the welding device 9 includes a TIG welding torch 901, a cylinder 902 and a lead screw module 903. The welding object is a straight seam of the barrel body. The lead screw module 903 drives the TIG welding torch 901 to move horizontally to complete the linear movement of wire feeding. At the same time, to avoid interference between the welding torch and the plate part, the cylinder 902 drives the TIG welding torch 901 to move up and down. The cylinder 902 drives the TIG welding torch 901 to move down to the corresponding position, and the position is adjustable, so that it can accurately reach the target position and realize wire feeding for welding.

[0059] Two groups of vision detection devices 10 are installed on the cross beam of the plate rolling machine; Reference Figure 13 , the vision detection device 10 includes a detection camera 1001, an angle adjustment device 1002 and a slide table assembly 1003. The detection camera 1001 is fixed on the slide table assembly 1003, and the slide table assembly 1003 is connected to the angle adjustment device 1002. The detection camera 1001 adjusts the angle through the angle adjustment device 1002 and adjusts the position of the camera through the slide table assembly 1003. The parts detected by the detection camera 1001 are whether the weld seam and the barrel body are qualified. By adjusting the position and angle through the angle adjustment device 1002 and the slide table assembly 1003, the comprehensive detection of the weld seam and the barrel body can be realized. The weld seam can be detected after the welding torch automatically completes the welding. Since the barrel body is a cylinder, it needs to be rotated to be completely detected.

[0060] In order to cooperate with the plate rolling machine for the curling of the sheet metal part 11 and the rotation detection requirement of the detection camera 1001, a fixture assembly 8 is set up. Reference Figure 9 , the fixture assembly 8 includes a six-axis drive member 801 and a roller fixture 802. The roller fixture 802 is internally provided with a through electromagnet for adsorbing the bent sheet metal part 11. The six-axis drive member 801 can adopt a six-axis robotic arm to drive the roller fixture 802 to obtain the bent sheet metal part 11 and wind it into a cylindrical structure, and cooperate with the welding device 9 to perform edge sealing welding on the cylindrical structure to form a cylindrical tank body 1103. After the welding is completed, the six-axis drive member 801 continues to drive the roller fixture 802 to rotate the cylindrical tank body 1103 in place, and cooperate with the vision detection device 10 to detect the deformation conditions and weld seam welding conditions of each position of the formed cylindrical tank body 1103.

[0061] Reference Figure 10, the drum fixture 802 is composed of two major parts: a titanium alloy drum frame and an electromagnet. The first circular plate 803 at the front end of the drum frame has the same diameter as the magnet to ensure the flatness of the sheet metal part 11 being rolled in. The second circular plate 804 at the back has a positioning function. The side of the sheet metal part 11 starts to adhere to the second circular plate 804 at the back when it is rolled into the drum, which can effectively prevent the sheet metal from being rolled crookedly.

[0062] Reference Figure 14 , the discharging device 5 provided in this embodiment includes a discharging conveyor belt 501 and a defective product recycling box 502. Through the recognition and feedback of the visual detection device 10, the six-axis driving member 801 drives the drum fixture 802 to place the cylindrical tank body 1103 on the discharging conveyor belt 501 or the defective product recycling box 502. After the visual detection device 10 detects the qualified products, they are placed on the discharging conveyor belt 501, and the defective products are placed in the defective product recycling box 502.

[0063] Reference Figure 1 , an automatic processing production line for a cylindrical tank body 1103 provided in this embodiment. During processing, the sheet metal parts 11 in sheet form are stored on the storage device 1 in the form of a stack. The driving material-taking trolley 104 uses the up-and-down and front-and-back movement of the material-taking fork 107 to obtain a sheet metal part 11 on the storage device 1 and transport it. The material-taking trolley 104 transports the sheet metal part 11 to the storage table 201 of the loading device 2 for storage. The vacuum adsorption fixture 203 of the loading device 2, under the drive of the three-axis driving device 204, obtains the sheet metal part 11, adjusts its position, and then places it on the first conveyor belt 301, which transports it to the first cutting device 6 for the cutting process. The first conveyor belt 301 identifies the transportation position and speed of the sheet metal part 11 under the induction of several sensors. When feeding the first cutting device 6, through the cooperation of the sensors and the speed-regulating motor, it accurately controls the width of the sheet metal part 11 entering the first cutting device 6, and can stop the transportation of the first conveyor belt 301 after reaching the specified width and enter the cutting of the first cutting device 6. The first cutting machine performs horizontal cutting. The cut first-stage sheet metal part 1101 enters the third conveyor belt 303 and continues to be transported. The third conveyor belt 303 adjusts the direction of the first-stage sheet metal part 1101 under the action of the diversion channel 304, so that it is centered and horizontally transported and fed to the second cutting device 7. Since the first-stage sheet metal part 1101 is a small sheet metal part 11 after cutting, it is easy to fall due to the center of gravity being outside when it leaves the third conveyor belt 303 by half the distance. Therefore, the first-stage sheet metal part 1101 is vertically clamped by the clamping device 305 and then enters the second cutting device 7 for vertical cutting. The cut second-stage sheet metal part 1102 is the final size before being processed into a tank body and rolled into a circle.

[0064] The secondary sheet metal part 1102 enters the second conveyor belt 302 for continuous transportation. Under the action of the diversion channel 304, the direction of the secondary sheet metal part 1102 is adjusted so that it is centered and horizontally transported and fed to the curling device 4. The secondary sheet metal part 1102 is curled at the curling device 4 to form the desired curvature. After the secondary sheet metal part 1102 is bent, the roller fixture 802 is driven by the six-axis drive member 801 to obtain the secondary sheet metal part 1102 and rotate in place, and wind it around to form the structure of the cylindrical tank body 1103. The welding device 9 is started to perform side edge sealing welding on the cylindrical tank body 1103. The argon arc welding gun 901 performs straight-line welding under the cooperation of the cylinder 902 and the lead screw module 903. The basic process of the production line for the cylindrical tank body 1103 is completed.

[0065] Before entering the finished product transportation, through the two sets of visual inspection devices 10 provided, the screening of the excellent rate of the finished product is carried out. The inspection camera 1001 is under the cooperation of the angle adjustment device 1002 and the slide table assembly 1003. At the same time, the roller fixture 802 is driven by the six-axis drive member 801 to rotate in place again. The inspection camera 1001 performs a comprehensive inspection of the weld seam and the cylinder body through rotation. After the inspection of the qualified products, they are placed on the discharge conveyor belt 501 under the drive of the six-axis drive member 801, and the defective products are placed in the defective product recycling box 502, so as to realize a series of processing procedures such as material storage, transportation, buffering, secondary shearing, curling welding inspection, etc.

[0066] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, using this concept to make non-substantive changes to the present invention, shall fall within the scope of infringement of the protection of the present invention.
