Description

Technical Field

[0001] This invention relates to an automatic gripping and corner-cutting device, specifically an automatic gripping and corner-cutting device for the outer body of a motorcycle fuel tank. Background Technology

[0002] Existing motorcycle fuel tanks are made by welding two symmetrical outer bodies together and then rolling them with the inner body around the perimeter. The existing inner and outer bodies are formed by stretching them using a hydraulic press mold, followed by trimming and punching in subsequent processes. In existing technology, an automatic feeding device for stretching the inner and outer steel plates of the fuel tank includes a material distribution assembly, a material gripping assembly (robot), and an automatic positioning and oiling assembly for the inner and outer steel plates, all arranged separately on a base plate. In use, stacked sheets are placed on the material distribution assembly. The material gripping assembly picks up one sheet at a time and transfers it to the automatic positioning and oiling assembly for positioning and oiling. After oiling, the material gripping assembly transfers the sheet to the hydraulic press mold for molding.

[0003] The drawbacks of the above structure are as follows: First, the material distribution assembly can only handle single-piece material handling at a time, while the mold of the hydraulic press can hold two pieces of material at a time. This requires multiple material handling and feeding by the material handling assembly (robot). Moreover, the spacing or placement angle between the two pieces of material varies during the hydraulic press molding process for different models of motorcycle fuel tanks. Therefore, this material distribution assembly requires the robot to handle the material multiple times, which not only prolongs the overall molding time and makes the production efficiency slower and relatively lagging, but also makes the material distribution device of this structure less versatile and unable to be used for the preliminary work of molding various different models of fuel tanks.

[0004] Secondly, some models of fuel tanks require corner cutting before the outer body is formed to reduce tensile resistance within the mold. The aforementioned structure cannot perform this corner cutting. Therefore, additional processing is needed for the compression molding of certain fuel tank models. The conventional corner cutting method involves manual cutting, followed by compression molding of the cut material in a hydraulic press. Since the two outer pieces weigh 9 kg each, and the inner piece approximately 5 kg, and with a daily production of 850 sets, one person producing the outer body needs to handle 7.65 tons of material per day. This is extremely labor-intensive, time-consuming, and inefficient. Therefore, it is necessary to design a cutting device that can replace manual labor and automatically cut the corners. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic gripping and corner cutting device for the outer body of an oil tank that can complete the dual-piece material picking in one go, improve material picking efficiency, is applicable to the preliminary work of molding various types of oil tanks, and can automatically position and cut the inner and outer body pieces of the oil tank, saving time and effort and achieving high production efficiency.

[0041] The positive effects of this invention are: After adopting the automatic gripping and corner-cutting device for the outer body of the fuel tank according to this invention, since this invention includes a double-sheet material distribution assembly, a double-station gripping assembly, and a double-station corner-cutting assembly arranged separately on the base plate,

[0042] The dual-station corner-cutting assembly includes a frame, and a material positioning mechanism, a cutting mechanism, and a waste recycling mechanism mounted on the frame.

[0045] In use, the dual-station material gripping assembly grips two material sheets from the dual-sheet dispensing assembly and transfers them to the dual stations on the frame. Each material sheet at each station is positioned by a corresponding material positioning mechanism to prevent displacement or shaking during corner cutting. Then, the X, Y, and Z-axis adjustment units are used to adjust the laser cutting head. The laser cutting head then cuts the corners of the material sheets. The cut waste falls into a waste recycling mechanism for unified collection, avoiding environmental pollution. After corner cutting, the material sheets are again placed into the mold of the hydraulic press by the dual-station material gripping assembly for molding. Furthermore, the corner-cut material sheets effectively reduce tensile resistance within the mold during molding.

[0046] This invention can complete the dual-piece material handling in one go, improving material handling efficiency. It is applicable to the preliminary work of molding various types of fuel tanks and can automatically position and cut the inner and outer body pieces of the fuel tank. Compared with the manual corner cutting method in the prior art, it not only has high production efficiency, but also reduces the labor intensity of workers and eliminates the need for the development of edge cutting molds. It can cut different sizes of different types and specifications of material pieces, making it more time-saving and labor-saving. Attached Figure Description

[0061] The present invention will be further described below with reference to the accompanying drawings and the given embodiments, but is not limited thereto.

[0062] like Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14, an automatic gripping and corner-cutting device for an oil tank body includes a double-piece material distribution assembly 1 for distributing materials, a double-station gripping assembly 2 for gripping materials, and a double-station corner-cutting assembly 3 for cutting corners of the material pieces, all arranged separately on a base plate 4. A hydraulic press is provided on the base plate and on one side of the double-station gripping assembly 2, and a protective railing is provided around the outer perimeter of the base plate to improve processing safety.

[0063] The dual-station corner cutting assembly 3 includes a frame 31, and a material positioning mechanism 32, a cutting mechanism 33, and a waste recycling mechanism 34 mounted on the frame 31. The frame 31 has two stations, and each station is equipped with a material positioning mechanism 32 for rotating and positioning the material sheet.

[0064] The cutting mechanism 33 includes a laser cutting head 331, an X-axis adjustment unit 332 for adjusting the laser cutting head in the X direction, a Y-axis adjustment unit 333 for adjusting the laser cutting head in the Y direction, and a Z-axis adjustment unit 334 for adjusting the laser cutting head in the Z direction.

[0065] The waste recycling mechanism 34 is located at the bottom of the frame 31 and is used to load the waste generated after the sheet cutting.

[0066] The dual-station material gripping assembly grips two material sheets from the dual-sheet material distribution assembly and transfers them to the dual stations on the frame 31. The material sheets at each station on the frame 31 are positioned by the corresponding material positioning mechanism 32. The X-axis adjustment unit 332, Y-axis adjustment unit 333, and Z-axis adjustment unit 334 adjust the laser cutting head 331 in the X, Y, and Z directions, respectively, and then perform corner cutting on the material sheets positioned by the material positioning mechanism 32. The cut waste falls into the waste recycling mechanism 34 for unified recycling.

[0067] like Figure 9 , 10 As shown in Figures 11, 12, 13, and 14, in order to be applicable to the processing of various specifications of external bodies, the material positioning mechanism 32 includes a drive motor 321, a rotating platform 322, a reference positioning component 323, and an adjustable positioning component 324 suitable for positioning different specifications of material pieces. The drive motor 321 is mounted on the frame 31, and the power output shaft of the drive motor 321 is connected to the rotating platform 322 to drive the rotation of the rotating platform 322 to achieve angular offset. The rotating platform 322 is provided with two reference positioning components 323 and two adjustable positioning components 324. One reference positioning component 323 and one adjustable positioning component 324 are connected to each other. The components 324 are arranged opposite each other, and another reference positioning component 323 is arranged opposite to another adjustable positioning component 324. Specifically, according to the specifications of the outer body of the oil tank that needs to be processed, and according to the placement position of the material piece in the mold, the drive motor 321 on each station of the frame 31 is pre-driven. The drive motor 321 drives the rotating table 322 to rotate at a certain angle. Then, the material piece is placed on the rotating table 322, and two sides of the material piece are pre-fitted close to the corresponding reference positioning component 323. Then, the remaining two sides of the material piece are abutted and positioned by the adjustable positioning component 324, thereby completing the precise positioning of the material piece.

[0068] The rotating platform 322 described in this invention has an irregular shape, which also facilitates the waste generated after the corners are cut into the waste recycling mechanism 34.

[0069] like Figure 10As shown, in order to position and press the sheet material to prevent it from shaking and affecting the cutting angle, one of the reference positioning components 323 is provided with a sheet material pressing mechanism 325 to press the sheet material to prevent shaking. The sheet material pressing mechanism 325 includes a pressing cylinder 3251, a pressing block 3252, a pressing connecting block 3253, a guide block 3254, and a cylinder seat 3255. The pressing cylinder 3251 is connected to the reference positioning component 323 through the cylinder seat 3255, and the push rod of the pressing cylinder 3251 is rotatably connected to the pressing block 3252 through a connector. The pressing connecting block 3253 is rotatably connected to the cylinder seat 3255, and the pressing block 3252 is rotatably connected to the pressing connecting block 3253. Guide blocks 3254 are provided on both sides of the pressing connecting block 3253, and the guide blocks 3254 are mounted on the reference positioning component 323. Specifically, after the sheet material is accurately positioned by the reference positioning component 323 and the adjustable positioning component 324, the clamping cylinder 3251 is driven, and the push rod drives the clamping block 3252 to press on the end face of the sheet material, thus completing the clamping action of the sheet material.

[0070] like Figure 10 As shown, in order to make the structure more reasonable and to achieve accurate positioning of the material, the reference positioning component 323 includes a positioning block connecting seat 3231 and a reference positioning block 3232. The reference positioning block 3232 is mounted on the rotary table 322 through the positioning block connecting seat 3231.

[0071] The adjustable positioning component 324 includes a slide rail base 3241, a slide rail 3242, a slider 3243, a positioning cylinder 3244, and a positioning plate 3245. The slide rail base 3241 is provided with two parallel slide rails 3242. The positioning cylinder 3244 is mounted on the slider 3243, and the slider 3243 slides in cooperation with the slide rail 3242. The positioning plate 3245 is fixed on the top rod of the positioning cylinder 3244. Specifically, the sheet is positioned along its length and width directions with its adjacent sides respectively using reference positioning blocks 3232. The remaining adjacent sides of the sheet are supported on the slide rail 3242. According to the actual specifications of the sheet, the slider 3243 slides along the slide rail 3242 and moves closer to one side of the sheet. At this time, the positioning cylinder 3244 on the slider 3243 is driven, and the top rod of the cylinder drives the positioning plate 3245 to position the sheet.

[0072] like Figure 10As shown, in order to support the material sheet and detect its presence, and to support material sheets with different cutting angles to ensure stable cutting, a reference positioning component 323 and an adjustable positioning component 324 arranged opposite to each other on the rotary table 322 are respectively provided with detection support components 326 for supporting and detecting the presence of material sheets. The detection support component 326 includes a connecting rod 3261, a rotating rod 3262 and a first proximity switch 3263. The reference positioning component 323 and the adjustable positioning component 324 are provided with connecting rods 3261 on both sides. The free end of the connecting rod 3261 is hinged to one end of the rotating rod 3262, and the other end of the rotating rod 3262 is provided with the first proximity switch 3263. Specifically: Adjust the rotating rod 3262 according to the size of the cutting angle, and the proximity switch 3263 is supported on the rotating platform 322. The material sheet is supported on the rotating rod 3262, and the proximity switch 3263 can play two roles: First, the cutting angle action can be further carried out only when the material sheet is detected on the rotating rod 3262; otherwise, the machine is stopped. Second, after the material sheet is cut, the first proximity switch 3263 detects that the cut waste material has completely fallen off, and only then can the gripping device (robot) grab the material and put it into the mold of the hydraulic press. This is to prevent waste material from entering the mold and causing damage to the material sheet inside the mold.

[0073] like Figure 11 As shown, to expand the functionality of the device, it can not only chamfer the outer body of the oil tank, but also apply oil to the inner body of the oil tank before molding. Similarly, to reduce the tensile resistance in the mold, a material sheet oiling mechanism 35 is provided on the frame 31 and located on the outer periphery of the material positioning mechanism 32. The material sheet oiling mechanism 35 includes a brush X-axis moving unit, a brush Y-axis moving unit, and a brush clamping and immersion oiling unit.

[0074] The brush X-axis moving unit includes a first motor 351 and an X-axis linear guide rail 352.

[0075] The brush Y-axis moving unit includes a second motor 353, a Y-axis linear guide rail 354, and a brush Y-axis moving slider 355. The frame 31 has Y-axis linear guide rails 354 on both sides of the dual-station along its width, and the two Y-axis linear guide rails 354 are connected by a linkage rod. The two ends of the X-axis linear guide rail are slidably engaged with the corresponding Y-axis linear guide rail 354 via the brush Y-axis moving slider 355. The motor shaft of the second motor 353 is connected to the X-axis linear guide rail 352.

[0076] The brush clamping and oiling unit includes a brush X-axis moving slider 356, a brush lifting cylinder 357, a brush 358, and an oiling box 359. The X-axis linear guide rail 352 is provided with two brush X-axis moving sliders 356 that slide with it and a limiting block 350 for limiting the movement of the brush 358. The two brush X-axis moving sliders 356 are detachably connected by a connecting plate. The first motor 351 drives one of the brush X-axis moving sliders 356. Each brush X-axis moving slider 356 is provided with a brush lifting cylinder 357. The top rod of the brush lifting cylinder 357 is equipped with two brushes 358 that can apply oil to the material sheet in the X and Y directions at one station. The frame 31 is provided with two separately arranged oiling boxes 359, and each oiling box 359 is provided with an oil scraper 3591 for scraping oil from the brush 358.

[0077] The specific oiling process inside the oil tank is as follows: When the push rod of the brush lifting cylinder 357 is extended, it causes the brush 358 to be immersed in the oil immersion box 359. Then, through the reciprocating motion of the push rod of the brush lifting cylinder 357, the excess oil on the brush 358 is scraped off by the oil scraper 3591.

[0078] According to the oiling trajectory, the second motor 353 is driven to operate. The two ends of the X-axis linear guide 352 slide back and forth along the corresponding Y-axis linear guide 354 via the brush Y-axis moving slider 355. An oiling brush 358 on the top rod of the brush lifting cylinder 357 applies Y-axis oiling to the material sheet.

[0079] The first motor 351 is driven to operate, the brush X-axis moving slider 356 slides back and forth along the X-axis linear guide rail 352, and another brush 358 on the top rod of the brush lifting cylinder 357 applies X-axis oil to the material sheet, finally completing the surface oiling of the material sheet.

[0080] like Figure 13 , 14 As shown, in order to achieve three-way adjustment of the laser cutting head, the X-axis adjustment unit 332 includes an X-axis slide rail 3321, an X-axis slider 3322, and a third motor 3323. The frame 31 is provided with X-axis slide rails 3321 on both sides along its length.

[0081] The Y-axis adjustment unit 333 includes a Y-axis slide rail 3331, a Y-axis slider 3332, and a fourth motor 3333. The Y-axis slide rail 3331 is mounted above the frame 31, and its two ends are slidably engaged with the X-axis slide rail 3321 via corresponding X-axis sliders 3322. The power output shaft of the third motor 3323 is drivenly connected to the X-axis slide rail 3321. The Y-axis slider 3332 is slidably engaged with the Y-axis slide rail 3331. The power output shaft of the fourth motor 3333 is drivenly connected to the Y-axis slide rail 3331.

[0082] The Z-axis adjustment unit 334 includes a Z-axis slide rail 3341, a Z-axis slider 3342, and a fifth motor 3343. The Z-axis slide rail 3341 is mounted on the Y-axis slider 3332, and the Z-axis slider 3342 is slidably engaged with the Z-axis slide rail 3341. The power output shaft of the fifth motor 3343 is connected to the Z-axis slide rail 3341. The laser cutting head 331 is mounted on the Z-axis slider 342.

[0083] Specifically, the third motor 3323 is driven to operate, and the Y-axis slide rail 3331 slides along the X-axis slide rail 3321 via the X-axis slider 3322, thereby realizing the X-axis movement of the Y-axis slide rail 3331.

[0084] The fourth motor 3333 is driven to operate, and the Z-axis slide rail 3341 slides along the Y-axis slide rail 3331 via the Y-axis slider 3332, thereby realizing the Y-axis movement of the Z-axis slide rail 3341.

[0085] The fifth motor 3343 is driven to operate, and the laser cutting head 331 slides along the Z-axis slide rail 3341 via the Z-axis slider 3342, thereby realizing the Z-axis movement of the Z-axis slide rail.

[0086] In this way, the laser cutting head 331 can move in the X, Y, and Z directions according to its running trajectory, and stop at a suitable position according to the processing requirements to achieve the corner cutting of the material.

[0087] like Figure 2 , 3 As shown in Figures 4, 5, and 6, in order to enable dual-piece material handling in one operation, not only is the overall molding time shortened and the production cycle reduced, but it also has strong versatility and can be applied to the material handling action before molding various different specifications of oil tanks. The dual-piece material distribution assembly 1 includes a base 11, a first piece bearing unit 12, and a second piece bearing unit 13.

[0088] The first sheet support unit 12 and the second sheet support unit 13 are arranged side by side on the base 11. The first sheet support unit 12 is fixed on the base 11, and the second sheet support unit 12 is slidably engaged with the base 11.

[0089] The first sheet support unit 12 includes a sheet fixing platform 121, a first sheet rotating platform 122, and a first dispensing component. The sheet fixing platform 121 is fixed on the base 11, and the first sheet rotating platform 122 is rotatably connected to the sheet fixing platform 121. The first dispensing component is provided on the sheet fixing platform 121 and on the outer periphery of the first sheet rotating platform 122. It can adjust the cage angle according to the sheet specifications and prevent the sheets from being difficult to separate due to stacking.

[0090] The second sheet support unit 13 includes a sheet slide 131, a second sheet rotary table 132, and a second dispensing assembly with the same structure as the first dispensing assembly. The sheet slide 131 is slidably engaged with the base 11, and the second sheet rotary table 132 is rotatably connected to the sheet slide 131. The base 11, located on the outer periphery of the second sheet rotary table 132, is provided with a second dispensing assembly that can adjust the cage angle according to the sheet specifications and prevent the sheets from being difficult to separate due to stacking.

[0091] The sheet slide 131 of the second sheet support unit 12 is slidably engaged with the base 11 via a sliding mechanism 16, used to adjust the distance between it and the first sheet support unit 12. The rotation angle of the first sheet rotating platform 122 relative to the sheet fixing platform 121 is symmetrical and consistent with the rotation angle of the second sheet rotating platform 132 relative to the sheet slide 131.

[0092] To facilitate the sliding of the sheet slide, the sliding mechanism 16 includes a linear slide rail 161, a slide block 162, and a rotary handwheel 163. The sheet slide 131 is detachably connected to the slide block 162, and the slide block 162 is drivenly connected to the linear slide rail 161. The rotary handwheel 163 is located at the end of the linear slide rail 161 and is drivenly connected to it. By rotating the handwheel 163, the sheet slide 131 moves linearly along the base 11 via the linear slide rail 161 under the action of the slide block 162. To make the sheet slide slide smoother and to provide a sliding guide, the linear slide rail 161 is located in the middle of the bottom of the sheet slide 131, and guide rail pairs 164 that slide and engage with the base 11 are respectively provided on both sides of the sheet slide 131.

[0093] To allow adjustment of the cage angle according to the sheet specifications and prevent difficulty in separation due to sheet stacking, both the first and second material separating components include a column 171, a magnetic sheet separator 173, and multi-stage adjustment plates 172. The column 171 is equipped with two sets of multi-stage rotatably connected adjustment plates 172, and each of the two sets of adjustment plates 172 at their free ends is equipped with a magnetic sheet separator 173. The column 171 of the first material separating component is mounted on the sheet fixing table 121, and the two sets of multi-stage adjustment plates 172 of the first material separating component respectively enclose the first sheet rotating table 121. Along its length and width, the column 171 of the second material distribution assembly is mounted on the base 11. Two sets of multi-stage adjustment plates 172 of the second material distribution assembly respectively enclose the second sheet rotating table 132 along its length and width. In use, the multi-stage adjustment plates 172 can be rotated and adjusted according to the actual specifications of the sheet to ensure they are enclosed on both sides of the rotating table. The two magnetic separators 173 can separate the top two sheets for easy material handling.

[0094] The rotation angle of the two material positioning mechanisms 32 on the dual-station frame 31 is consistent with the rotation angle of the first material sheet rotary table 122 and the second material sheet rotary table 132. The dual-station material gripping assembly simultaneously grips the material sheets from the first material sheet rotary table 122 and the second material sheet rotary table 132, and places the two material sheets on the two material positioning mechanisms 32 on the dual-station frame 31 respectively.

[0095] like Figure 5 , 6 As shown, in order to perform reference positioning of the sheet and to facilitate the rotation of the sheet rotary table, the first sheet rotary table 122 is provided with a first sheet positioning rod 123 along its length and width, and the second sheet rotary table 132 is provided with a second sheet positioning rod 133 along its length and width. The sheet rotary table can be rotated directly by manipulating the sheet positioning rods to offset and rotate it.

[0096] In order to detect whether there are still pieces on the rotating table, and to provide an alarm reminder for the equipment, the robot will not perform the next action if there are no pieces. The first rotating table 22 and the second rotating table 32 are each equipped with a second proximity switch 14 for detecting whether there are pieces on the rotating table, and a switch base 141 for installing the proximity switch. The second proximity switch 14 is assembled and connected to the corresponding switch base 141.

[0097] like Figure 4 As shown, to make the structure more reasonable and facilitate the rotation of the two rotating platforms relative to the fixed platform and the sliding platform respectively, the material sheet fixing platform 121 has a first rotating groove 1211. The bottom of the first material sheet rotating platform 122 is provided with ball bearings, which rotate along the first rotating groove 1211, causing the first material sheet rotating platform 122 to rotate and shift relative to the material sheet fixing platform 121. The material sheet sliding platform 131 has a second rotating groove 1311, and the bottom of the second material sheet rotating platform 132 is provided with ball bearings, which rotate along the second rotating groove 1311, causing the second material sheet rotating platform 132 to rotate and shift relative to the material sheet sliding platform 131.

[0098] To further accurately determine whether the rotation angles of the two sheet rotating platforms are symmetrical, the sheet fixing platform 121 and the sheet slide 131 are respectively provided with scales for measuring the rotation angle of the sheet. The first sheet rotating platform 122 and the second sheet rotating platform 132 are respectively provided with scale display slots 15 corresponding to the scales. After confirming that the angles are consistent, the middle part of the two sheet rotating platforms is provided with waist-shaped holes. Bolts are inserted into the corresponding waist-shaped holes and screwed into the screw holes of the fixing platform or the sheet slide, so that the sheet fixing platform 122 is fixed to the first sheet rotating platform 121 by bolts, and the sheet slide 132 is fixed to the second sheet rotating platform 131 by bolts.

[0099] like Figure 7 , 8 As shown, in order to achieve the gripping of two pieces of material, the dual-station gripping assembly 2 includes a lever arm 21, a gripping support connecting rod 22, a gripping unit 23, and a six-axis robot 24.

[0100] The lever arm 21 and the gripping support connecting rod 22 are arranged perpendicularly to each other. One end of the lever arm 21 is fixedly connected to the gripping support connecting rod 22, and the other end is drivenly connected to the transmission arm of the six-axis robot 24. The gripping support connecting rod 22 is provided with multiple gripping units 23 arranged in pairs and capable of gripping two pieces of material simultaneously.

[0101] The two gripping units 23 on each pair of gripping support connecting rods 22 are arranged in opposite directions. Each gripping unit 23 includes a gripping support 231, a suction cup holder 232, and a suction cup 233. One end of the gripping support 231 is fitted onto and detachably connected to the gripping support connecting rod 22, and the other end is provided with a suction cup holder 232. The suction cup 233 is mounted on the suction cup holder 232. Specifically, two pieces of material can be adsorbed by the suction cup 233, and the material can be gripped by the movement of the six-axis robot 24.

[0102] like Figure 13 As shown, dust is generated during the laser cutting of the sheet material. In order to prevent environmental pollution and even contamination of equipment components, the frame 31 has a dust suction pipe 36 connected to a fan along its width direction for sucking up the dust generated during cutting. The dust suction pipe 36 has dust suction holes along its length direction.

[0103] like Figure 13 , 14 As shown, to further extend the functionality of the device, a support frame 37 for cutting precast slabs is provided on the frame 31 and located on the outside of one workstation. This invention utilizes a cutting mechanism to cut precast slabs. The support frame 37 has multiple support bars, and each support bar has a support block, which can be used to prevent movement of the precast slabs during the cutting process.

[0104] like Figure 12 As shown, for convenient unified recycling, the waste recycling mechanism 34 includes multiple identical waste recycling trolleys 341. These trolleys are arranged side-by-side at the bottom of the frame 31 and below the dual workstations. Each trolley 341 also has a handle 342 on one side for easy pulling out. In use, the waste recycling trolley 341 catches the cutting material falling from above. Once full, the handle 42 is used to pull the trolley 341 directly out from the bottom of the frame 1 for unified processing.

[0105] The working process of this invention:

[0106] Material distribution: Based on the required specifications of the oil tank and the spacing and placement angle between the two material plates inside the hydraulic press, the distance between the first and second material plate bearing units is adjusted using a sliding mechanism. This is achieved by rotating the handwheel 163. Under the action of the slide block 162, the material plate slide table 131 moves linearly along the base 1 via the linear slide rail 161.

[0107] Adjust the rotation angles of the first and second sheet rotating platforms and maintain symmetry. This is achieved by manipulating the first sheet positioning rod 123, causing the ball bearings at the bottom of the first sheet rotating platform 122 to rotate along the first rotating groove 1211, thus causing the first sheet rotating platform 122 to rotate and shift relative to the sheet fixing platform 121.

[0108] Manipulating the second sheet positioning rod 133 causes the ball bearings at the bottom of the second sheet rotating platform 132 to rotate along the second rotating groove 1311, causing the second sheet rotating platform 132 to rotate and shift relative to the sheet slide 131. Based on the scales on the sheet fixing platform 121 and the sheet slide 131 used to measure the sheet rotation angle, it is precisely determined whether the rotation angles of the two sheet rotating platforms are consistent.

[0109] Material sheets are placed on the first material sheet rotating table 122 and the second material sheet rotating table 132 respectively. The multi-stage adjustment plate 172 can be rotated and adjusted according to the actual specifications of the material sheets to ensure that they can be wrapped around the other side of the rotating table along its length direction and the other side along its width direction. The two magnetic separators 173 can separate the top two material sheets. The robot can pick up the two material sheets at the same time. At the same time, the magnetic separators 173 of the first and second material separation components of the present invention can separate the top material sheets of the two stacks of material sheets to prevent them from sticking together after being stacked and making them difficult to pick up. It also avoids the possibility of picking up too many materials at once.

[0110] Material handling: Drive the six-axis robot 24 to pick up the material pieces on the first material piece rotary table 122 and the second material piece rotary table 132 through the suction cup 233, and place the material pieces on the material positioning mechanism 32 after the material picking is completed.

[0111] For machining the interior of the fuel tank, only oiling is required. For machining the exterior, the corners are generally chamfered. Of course, there may be specific technical requirements that necessitate both chamfering and oiling the exterior. Specifically:

[0112] Positioning: Based on the specifications of the outer body of the oil tank to be processed and the placement position of the material pieces inside the mold, the drive motors 321 on each station of the frame 31 are pre-driven. The drive motors 321 drive the rotating table 322 to rotate at a certain angle. The rotation angle of the rotating table 322 is consistent with the rotation angle of the two material piece rotating tables. The rotating rod 3262 is pre-adjusted according to the cutting angle, and the proximity switch 3263 is supported on the rotating table 322.

[0113] The sheet is positioned along its length and width directions, with adjacent sides positioned by reference positioning blocks 3232. The sheet is supported on a rotating rod 3262, and the remaining adjacent sides are supported on a slide rail 3242. According to the actual specifications of the sheet, the slider 3243 slides along the slide rail 3242 and approaches one side of the sheet. At this time, the positioning cylinder 3244 on the slider 3243 is driven, and the top rod of the cylinder drives the positioning plate 3245 to position the sheet. After the sheet is accurately positioned by the reference positioning component 323 and the adjustable positioning component 324, the clamping cylinder 3251 is driven, and the top rod drives the clamping block 3252 to press against the end face of the sheet, completing the clamping action of the sheet. The next step can only be performed when the proximity switch 3263 detects the presence of the sheet.

[0114] Internal process (oiling): When the push rod of the brush lifting cylinder 357 is pushed out, it drives the brush 358 to be immersed in the oil immersion box 359. Then, through the reciprocating motion of the push rod of the brush lifting cylinder 357, the excess oil on the brush 358 is scraped off by the scraper plate 3591.

[0115] According to the oiling trajectory, the second motor 353 is driven to operate. The two ends of the X-axis linear guide 352 slide back and forth along the corresponding Y-axis linear guide 354 via the brush Y-axis moving slider 355. An oiling brush 358 on the top rod of the brush lifting cylinder 357 applies Y-axis oiling to the material sheet.

[0116] The first motor 351 is driven to move, and the brush X-axis moving slider 356 slides back and forth along the X-axis linear guide rail 352. Another brush 358 on the top rod of the brush lifting cylinder 357 applies X-axis oil to the material sheet. Finally, the surface of the material sheet is oiled. The oiled material sheet is then placed in the mold of the hydraulic press by the material gripping device and molded.

[0117] External body process (corner cutting): The third motor 3323 is driven to operate, and the Y-axis slide rail 3331 slides along the X-axis slide rail 3321 via the X-axis slider 3322, thereby realizing the X-axis movement of the Y-axis slide rail 3331.

[0118] The fourth motor 3333 is driven to operate, and the Z-axis slide rail 3341 slides along the Y-axis slide rail 3331 via the Y-axis slider 3332, thereby realizing the Y-axis movement of the Z-axis slide rail 3341.

[0119] The fifth motor 3343 is driven to operate, and the laser cutting head 331 slides along the Z-axis slide rail 3341 via the Z-axis slider 3342, thereby realizing the Z-axis movement of the Z-axis slide rail.

[0120] In this way, the laser cutting head 331 can move in the X, Y, and Z directions according to its running trajectory, and stop at a suitable position according to the processing requirements to achieve the corner cutting of the material sheet. The oiled material sheet is then placed in the mold of the hydraulic press by the material gripping device to be molded. The waste recycling trolley 341 catches the cutting material falling from above. After it is full of cutting material, the waste recycling trolley 341 is directly pulled out from the bottom of the frame 31 by the handle 342 for unified processing.

[0121] The dual-piece material distribution assembly of this invention enables the material gripping assembly to complete the picking of two pieces at once, and can directly adjust the spacing and / or rotation angle between the two pieces, making it highly versatile and applicable to the preliminary work of molding various types of fuel tanks. It not only shortens the overall molding time and production cycle, but also has strong versatility and can be used for the material picking action before molding various specifications of fuel tanks.

[0122] This invention eliminates the development costs of the outer steel plate corner cutting mold and the need for manual mold maintenance. The corner cutting dimensions can be adjusted through program programming, thereby achieving the optimal stretched appearance of the outer body.

[0123] This invention enables automatic cutting of sheet metal. Compared to the existing technology of manually feeding sheet metal into a punch press for corner cutting and manually feeding the cut sheet metal into a hydraulic press for stretching and forming, this invention replaces manual operation, reducing the need for two people for corner cutting and manual feeding and stretching. This not only improves production efficiency but also reduces the labor intensity of workers, making it more time-saving and labor-saving. At the same time, this invention can also automatically apply oil to the sheet metal. Thus, different sizes of corners or oil can be cut or applied to the inner and outer bodies of oil tanks of different models and specifications on one machine, and the machines can be automatically transferred, improving the efficiency of molding.

[0124] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
