Description

Technical Field

[0001] The present invention relates to the technical field of stamping processing, and particularly to a stamping production line. Background Art

[0002] With the continuous development of society and the continuous progress of technology, mechanized, automated, and standardized production has gradually become the development trend, and the traditional manual production method can no longer meet the development requirements of the times.

[0003] Generally, stamped parts need to go through multiple different stamping processes to obtain finished products. The traditional operation method is to place the stamped parts on one of the workstations for stamping, and then transfer the semi-finished stamped parts to another workstation for stamping through a semi-automatic method of manually operating the transfer equipment. During the process of transferring the semi-finished stamped parts by semi-automatic manual means and then stamping them, a large amount of time is consumed, which not only reduces the production efficiency, but also the product accuracy cannot be well guaranteed. Especially for the transfer of large stamped parts (such as automotive panel parts), the manpower and material resources consumed will be greater, and it is more difficult to guarantee the stamping accuracy.

[0004] During the process of developing the mechanization, automation, and standardization of sheet material production equipment, equipment developers need to consider how to achieve automated stamping processing operations for large stamped parts, so as to improve production efficiency.

[0036] For ease of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present invention can be understood more thoroughly and comprehensively.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0039] As Figure 1 shown, it is a structural diagram of a stamping production line 10 according to an embodiment of the present invention.

[0040] A stamping production line 10 includes: a stamping part loading mechanism 100, a positioning and centering table mechanism 200 and a stamping device 300. The positioning and centering table mechanism 200 is arranged between the stamping part loading mechanism 100 and the stamping device 300. There are multiple stamping devices 300, and a hanging transfer manipulator 400 is installed between two adjacent stamping devices 300.

[0041] Furthermore, the hanging transfer manipulator 400 is also installed on the first stamping device 300 and the last stamping device 300 to complete the loading and unloading operations of the stamping parts.

[0042] AsFigure 2 As shown in the figure, the stamping part feeding mechanism 100 includes a stamping part feeding manipulator 110 and a stamping part conveying table 120. The stamping part conveying table 120 is slidably arranged below the stamping part feeding manipulator 110.

[0043] Combined with Figure 3 and Figure 4 As shown in the figure, the stamping part feeding manipulator 110 includes: a feeding frame 111, a feeding sliding plate 112 slidably installed on the feeding frame 111, a feeding driving part 113 drivingly connected to the feeding sliding plate 112, a feeding lifting sliding plate 114 slidably installed on the feeding sliding plate 112, and a feeding lifting driving part 115 drivingly connected to the feeding lifting sliding plate 114. A plurality of feeding suction cup assemblies 116 are installed on the feeding lifting sliding plate 114.

[0044] As Figure 5 shown, the feeding driving part 113 includes: a guiding slide rail 113a, a feeding transmission rack 113b, a feeding transmission gear 113c, and a feeding transmission motor 113d. The guiding slide rail 113a and the feeding transmission rack 113b are installed on the feeding frame 111. The feeding transmission motor 113d is installed on the feeding sliding plate 112 and drivingly connected to the feeding transmission gear 113c. The feeding transmission gear 113c meshes with the feeding transmission rack 113b. The feeding sliding plate 112 is slidably installed on the guiding slide rail 113a.

[0045] It should be noted that the feeding transmission motor 113d drives the feeding transmission gear 113c to rotate, thereby driving the feeding sliding plate 112 to reciprocate on the guiding slide rail 113a, thus realizing the sliding operation of the feeding sliding plate 112 on the feeding frame 111. By adopting the transmission structure of a gear and a rack, the moving accuracy of the feeding sliding plate 112 can be guaranteed, thereby improving the working accuracy of the stamping part feeding manipulator 110.

[0046] Similarly, the feeding lifting driving part 115 adopts a transmission structure similar to that of the feeding driving part 113, which is a gear and a rack, to drive the feeding lifting sliding plate 114 to lift, so that the lifting movement accuracy of the feeding lifting sliding plate 114 is higher.

[0047] As Figure 6 shown, the feeding suction cup assembly 116 includes: a feeding suction rod 116a, a feeding suction nozzle 116b, and a feeding buffer spring 116c. The feeding suction nozzle 116b is installed at one end of the feeding suction rod 116a. The feeding buffer spring 116c is connected between the feeding suction rod 116a and the feeding suction nozzle 116b.

[0048] It should be noted that the loading suction cup assembly 116 is installed on the loading lifting slide plate 114. Through the movement of the loading sliding plate 112 and the loading lifting slide plate 114, the loading suction cup assembly 116 comes above the stamping part conveying table 120 and sucks the stamping parts. By setting the loading buffer spring 116c, damage to the stamping parts can be prevented when sucking the stamping parts. After the loading suction cup assembly 116 sucks the stamping parts, the stamping parts are loaded onto the positioning and centering table mechanism 200 through the movement of the loading sliding plate 112 and the loading lifting slide plate 114 for centering operation.

[0049] As Figure 7 shown, the stamping part conveying table 120 includes: a sliding conveying base 121, a stamping part limiting and rotating assembly 122 and a magnetic force separating assembly 123. There are multiple stamping part limiting and rotating assemblies 122 and they are installed on the outside of the sliding conveying base 121, and the magnetic force separating assembly 123 is installed on the stamping part limiting and rotating assembly 122.

[0050] Furthermore, the stamping part limiting and rotating member 122 includes: a first rotating shaft 122a, a first rotating adjustment block 122b rotatably installed on the first rotating shaft 122a, a second rotating shaft 122c installed at one end of the first rotating adjustment block 122b, and a second rotating adjustment block 122d rotatably installed on the second rotating shaft 122c. The magnetic force separating assembly 123 is installed on the second rotating adjustment block 122d.

[0051] In this embodiment, the magnetic force separating assembly 123 includes: a limiting mounting seat 123a, a limiting guide plate 123b and a limiting driving part 123c. The limiting mounting seat 123a is rotatably installed on the second rotating adjustment block 122d, and the limiting driving part 123c drives the limiting guide plate 123b to perform telescopic movement on the limiting mounting seat.

[0052] Furthermore, a separating magnetic strip 123d is provided on the limiting guide plate 123b, and the limiting driving part 123c is a limiting driving cylinder. By setting the separating magnetic strip 123d, the stacked stamping parts can be contacted. The separating magnetic strip 123d makes two adjacent stamping parts become the same pole, and the two stamping parts with the same pole repel each other, thereby separating the two stamping parts. Ensure that the stamping part loading manipulator 110 performs the loading operation on a single stamping part. Solve the problem of overlapping loading of stamping parts.

[0053] It should be noted that the sliding conveying base 121 is used to place the stamping parts, and the stamping parts are stacked on the sliding conveying base 121. After the stamping parts are placed, the positions of the stamping part limiting and rotating assembly 122 and the magnetic force separating assembly 123 need to be adjusted to limit the placement position of the stamping parts and prevent their position from shifting during the conveying process.

[0054] Specifically, by rotating to adjust the first rotation adjustment block 122b and the second rotation adjustment block 122d, the position of the magnetic force separating component 123 is adjusted. After the position of the magnetic force separating component 123 is completed, the limit drive part 123c drives the limit guide plate 123b to perform telescopic movement, so as to clamp or loosen the overlapping stamped parts, thereby adapting to the operation of the stamped part loading manipulator 110 to pick up the stamped parts.

[0055] By providing the first rotation shaft 122a and the second rotation shaft 122c, the adjustment range of the magnetic force separating component 123 can be made wider, thereby adapting to the operations of stamped parts of different specifications. Rotation locking blocks 122e are installed on both the first rotation shaft 122a and the second rotation shaft 122c. After the first rotation adjustment block 122b and the second rotation adjustment block 122d are adjusted, they are locked and fixed by the rotation locking blocks 122e.

[0056] Please refer to again Figure 7 , a guide slide rail 121a is installed on the outside of the sliding transport base 121, and the stamped part limit rotation assembly 122 is installed on the guide slide rail 121a. By providing the guide slide rail 121a, the position of the stamped part limit rotation assembly 122 can be adjusted, thereby adapting to the operations of stamped parts of different specifications.

[0057] Furthermore, a plurality of limit grooves 121b are provided on the sliding transport base 121, and scale lines (not shown in the figure) are provided on the limit grooves 121b. The provision of the limit grooves 121b can, on the one hand, increase the friction on the sliding transport base 121 to prevent the stamped parts from sliding on the sliding transport base 121, and on the other hand, the scale lines provided on the limit grooves 121b can make the position adjustment of the stamped part limit rotation assembly 122 more accurate.

[0058] Please refer to again Figure 2 , a positioning and centering table mechanism 200 includes a magnetic force conveying device 210 and a centering and positioning device 220, and the magnetic force conveying device 210 and the centering and positioning device 220 are connected to each other.

[0059] As Figure 8As shown in the figure, the magnetic conveying device 210 includes: a magnetic conveying base 211, a magnetic conveying rotating rod 212 rotatably mounted on the magnetic conveying base, a plurality of magnetic conveying guiding blocks 213 mounted on the magnetic conveying rotating rod 212, and a magnetic conveying driving motor 214 drivingly connected to the magnetic conveying rotating rod 212. The magnetic conveying guiding blocks 213 are mounted on the magnetic conveying base 211 and are rotatably connected to the magnetic conveying rotating rod 212 at one end. A plurality of magnetic conveying magnets 215 are mounted on the magnetic conveying guiding blocks 213, and a magnetic conveying belt 216 is mounted on the magnetic conveying guiding blocks 213. The magnetic conveying magnets 215 are disposed between the magnetic conveying belt 216 and the magnetic conveying guiding blocks 213.

[0060] Furthermore, magnetic guiding slide rods 217 are mounted on both sides of the magnetic conveying guiding blocks 213, and a plurality of magnetic guiding rollers 218 are mounted on the magnetic guiding slide rods 217.

[0061] In this embodiment, a rotating gear is mounted on the magnetic conveying rotating rod 212, and the magnetic conveying driving motor 214 is drivingly connected to the rotating gear through a synchronous belt. Thus, the magnetic conveying rotating rod 212 is rotated by the driving of the magnetic conveying driving motor 214, thereby driving the magnetic conveying belt 216 on the magnetic conveying guiding blocks 213 to perform a conveying movement.

[0062] It should be noted that after the stamping part loading manipulator 110 grabs and places the stamping part on the magnetic conveying device 210, the magnetic conveying belt 216 on the magnetic conveying guiding blocks 213 is moved by the driving of the magnetic conveying driving motor 214, so that the stamping part is conveyed from the magnetic conveying device 210 to the centering and positioning device 220 for centering and positioning processing.

[0063] Since the position of a large stamping part (such as an automobile sheet metal part) is likely to shift during transmission, the magnetic conveying magnets 215 can be provided to suck and fix the stamping part, preventing the stamping part from shifting in position during transmission. At the same time, by mounting the magnetic guiding slide rods 217 and the magnetic guiding rollers 218 on both sides of the magnetic conveying guiding blocks 213, a guiding and lubricating effect can be achieved, making the transmission process of the stamping part smoother and more stable.

[0064] As Figure 9 shown in the figure, the centering and positioning device 220 includes: a centering base 221, a first conveying part 222 and a second conveying part 223. The first conveying part 222 and the second conveying part 223 have the same structure and are symmetrically arranged and mounted on the centering base 221. Positioning and centering parts 224 are movably mounted on both the first conveying part 222 and the second conveying part 223.

[0065] Further, the first conveying part 222 includes a centering conveying rotating rod 222a and a centering conveying assembly 222b mounted on the centering conveying rotating rod 222a. A centering conveying belt 222c is mounted on the centering conveying assembly 222b.

[0066] The centering conveying assembly 222b includes: a centering conveying guide seat 222e, a first centering transmission gear 222f and a second centering transmission gear 222g mounted at both ends of the centering conveying guide seat 222e. The first centering transmission gear 222f is rotatably mounted on the centering conveying rotating rod 222a. The centering conveying belt 222c is respectively meshed with the first centering transmission gear 222f and the second centering transmission gear 222g. A centering driving gear 222h is mounted on the centering conveying rotating rod 222a. The centering positioning device 220 further includes a centering conveying driving part 225. The centering conveying driving part 225 is drivingly connected to the centering driving gear 222h through a conveyor belt (not shown in the figure). Thus, the centering driving gear 222h is rotated by the drive of the centering conveying driving part 225, thereby driving the centering conveying rotating rod 222a to rotate, so that the first centering transmission gear 222f rotates, and the centering conveying belt 222c performs related conveying movements.

[0067] In this embodiment, the centering conveying driving part 225 is a motor. A plurality of centering conveying assemblies 222b are provided and are mounted on the centering conveying rotating rod 222a in parallel.

[0068] It should be noted that when the magnetic conveying device 210 is conveyed to the centering positioning device 220, the first conveying part 222 conveys the stamping part to the second conveying part 223 through the transmission structure of the centering conveying rotating rod 222a and the centering conveying assembly 222b. The second conveying part 223 performs a conveying operation on the stamping part through the same transmission principle. While the stamping part is being conveyed, the centering and positioning part 224 works to perform a centering operation on the stamping.

[0069] As Figure 10 shown, the centering and positioning part 224 includes: a centering fixing plate 224a, a centering sliding plate 224b slidably mounted on the centering fixing plate, a centering lifting assembly 224c mounted on the centering sliding plate 224b, and a centering lifting guide rod 224d drivingly connected to the centering lifting assembly 224c. The centering fixing plate 224b is mounted below the first conveying part 222 or the second conveying part 223. The centering lifting assembly 224c drives the centering lifting guide rod 224d to movably pass through the first conveying part 222 or the second conveying part 223.

[0070] In this embodiment, the centering lifting assembly 224c is a lifting cylinder. The centering lifting guide rod 224d is driven by the lifting cylinder to rise onto the first conveying part 222 or the second conveying part 223.

[0071] Furthermore, the centering lifting guide rod 224d includes a centering lifting bottom plate 224e, a first centering limit post 224f, and a second centering limit post 224g. The first centering limit post 224f and the second centering limit post 224g are installed at both ends of the centering lifting bottom plate 224e. The centering conveying assembly 222b is disposed between the first centering limit post 224f and the second centering limit post 224g. The centering lifting bottom plate 224e is drivingly connected to the centering lifting assembly 224c.

[0072] It should be noted that a positioning centering part 224 is provided below each centering conveying assembly 222b. When the stamping part is conveyed through the first conveying part 222 and the second conveying part 223, the centering sliding plate 224b reaches the set position. The centering lifting guide rod 224d moves upward under the drive of the centering lifting assembly 224c, so that the first centering limit post 224f and the second centering limit post 224g come into contact with the stamping part, thereby restricting the position of the stamping part. By providing the positioning centering part 224 on both the first conveying part 222 and the second conveying part 223, both ends of the stamping part are clamped by the first centering limit post 224f and the second centering limit post 224g, so as to achieve the functions of position limitation and centering, which is convenient for the suspended conveying manipulator 400 to pick up the stamping part and feed it to the stamping equipment 300 for stamping operation, making the feeding accuracy higher and effectively improving the stamping accuracy.

[0073] Combined with Figure 9 and Figure 11 As shown, a stamping part thickness measuring device 230 is installed between the first conveying part 222 and the second conveying part 223. The stamping part thickness measuring device 230 includes a thickness measuring moving slide plate 231, a thickness measuring lifting cylinder 232 installed on the thickness measuring moving slide plate 231, and a thickness measuring lifting assembly 233 drivingly connected to the thickness measuring lifting cylinder 232.

[0074] The thickness measuring lifting assembly 233 includes a thickness measuring lifting guide rod 233a, a thickness measuring abutting piece 233b movably installed at one end of the thickness measuring lifting guide rod 233a, and a thickness measuring return spring 233c sleeved on the thickness measuring lifting guide rod 233a. One end of the thickness measuring return spring 233c is connected to the thickness measuring abutting piece 233b, so that the thickness measuring abutting piece 233b can perform a reset operation on the thickness measuring lifting guide rod 233a.

[0075] Furthermore, a thickness measuring through hole 233d is formed on the thickness measuring abutting piece 233b, and a thickness detector (not shown in the figure) is installed below the thickness measuring abutting piece 233b. The thickness detector is located below the thickness measuring through hole 233d.

[0076] It should be noted that after the stamping part is centered and positioned on the centering positioning device 220, the thickness measurement moving slide plate 231 moves to the corresponding position, and under the drive of the thickness measurement lifting cylinder 232, the thickness measurement abutting piece 233b abuts against the stamping part, and then the thickness of the stamping part is detected by the thickness detector, so as to determine the number of stamping parts, prevent the stamping parts from being overlapped during feeding under the action of magnetic force, ensure that the stamping parts fed onto the stamping equipment 300 are one piece, so that the stamping work can proceed orderly.

[0077] As Figure 12 shown, a suspended transfer manipulator 400 includes: a suspended mounting frame 410, a transfer sliding block 420 that reciprocates in the horizontal direction of the suspended mounting frame 410, a transfer lifting device 430 mounted on the transfer sliding block 420, a transfer lifting plate 440 that is drivingly connected to the transfer lifting device 430, a transfer telescopic cross bar 450 that reciprocates in the horizontal direction of the transfer lifting plate 440, and a transfer suction nozzle device 460 slidably disposed on the transfer telescopic cross bar 450.

[0078] Furthermore, a transfer rack 411 and a transfer guide rail 412 are mounted on the suspended mounting frame 410, and the transfer sliding block 420 is slidably mounted on the transfer guide rail 412. A transfer driving part 421 is mounted on the transfer sliding block 420, and a transfer gear (not shown in the figure) that meshes with the transfer rack 411 is drivingly mounted on the transfer driving part 421. In this embodiment, the transfer driving part 421 is a driving motor.

[0079] It should be noted that the transfer driving part 421 drives the transfer gear to rotate, so that the transfer gear works on the transfer rack 411, thereby driving the transfer sliding block 420 to slide horizontally on the suspended mounting frame 410, so as to move the transfer suction nozzle device 460 to the corresponding position for feeding or discharging operations.

[0080] Combined Figure 12 with Figure 13 shown, the transfer lifting device 430 includes: a transfer lifting guide plate 431, a transfer lifting motor 432 mounted on the transfer lifting guide plate 431, and a transfer lifting gear (not shown in the figure) that is drivingly connected to the transfer lifting motor 432. A transfer lifting guide rack 433 is mounted on the transfer lifting guide plate 431, and the transfer lifting guide rack 433 meshes with the transfer lifting gear. The transfer lifting plate 440 is mounted on one end of the transfer lifting guide plate 431. The transfer lifting guide plate 431 drives the transfer lifting guide rack 433 and the transfer lifting gear to mesh and move through the transfer lifting motor 432, so as to perform a lifting movement on the transfer sliding block 420, thereby driving the transfer lifting plate 440 to perform a lifting movement. So that the transfer suction nozzle device 460 can complete the lifting movement during feeding or discharging.

[0081] Please refer to again Figure 12 On the transfer lifting plate 440, a telescopic driving part 441 is installed, and a telescopic transfer gear (not shown in the figure) is drivingly installed on the telescopic driving part 441.

[0082] Furthermore, a telescopic rack 451 is installed on the transfer telescopic cross bar 450, and the telescopic rack 451 meshes with the telescopic transfer gear. In this embodiment, the telescopic driving part 441 is a driving motor.

[0083] It should be noted that the telescopic driving part 441 drives the telescopic transfer gear to rotate, so that the telescopic transfer gear cooperates with the telescopic rack 451 to move, thereby driving the transfer telescopic cross bar 450 to slide on the transfer lifting plate 440. Thus, the transfer operation of the stamping parts is completed.

[0084] The transfer sliding block 420, the transfer lifting device 430 and the transfer telescopic cross bar 450 all adopt a gear-rack transmission structure, so that the moving precision is higher and the movement is more stable.

[0085] Combined with Figure 13 and Figure 14 As shown, a plurality of transfer rotating wheels 452 are installed at both ends of the transfer telescopic cross bar 450, and the plurality of transfer rotating wheels 452 are drivingly connected through a transfer synchronous belt (not shown in the figure), and the transfer suction nozzle device 460 and the transfer lifting plate 440 are respectively meshed with the transfer synchronous belt.

[0086] Furthermore, the transfer suction nozzle device 460 includes a suction nozzle transfer slider 461 and a suction nozzle assembly 462 installed on the suction nozzle transfer slider. The suction nozzle transfer slider 461 is slidably installed on the transfer telescopic cross bar 450, and a transmission connection block 463 is installed on a surface of the suction nozzle transfer slider close to the transfer telescopic cross bar 450. The transfer synchronous belt is movably passed between the transmission connection block 463 and the suction nozzle transfer slider 461 and meshes with the transmission connection block 463.

[0087] As Figure 15 shown, a synchronous connection block 442 is fixedly installed on the transfer lifting plate 440, and the transfer synchronous belt is movably passed between the transfer lifting plate 440 and the synchronous connection block 442 and meshes with the synchronous connection block 442.

[0088] It should be noted that both the transmission connection block 463 and the synchronous connection block 442 are provided with rotating tooth structures, which are engaged with the transmission synchronous belt by setting the rotating tooth structures. When the transmission telescopic cross bar 450 slides telescopically on the transmission lifting plate 440, under the action of the transmission connection block 463 and the synchronous connection block 442, the transmission synchronous belt will be driven to rotate, so that the transmission rotating wheels 452 at both ends of the transmission telescopic cross bar 450 rotate, thereby driving the nozzle transmission slider 461 to move synchronously on the transmission telescopic cross bar 450. When the transmission telescopic cross bar 450 moves, the stamping parts on the nozzle assembly 462 also move synchronously, thus shortening the distance between two adjacent stamping devices 300, solving the problem that the traditional manipulator is prone to shaking when the lateral distance is larger, and making the handling and movement of the stamping parts more stable.

[0089] By adopting the matching structure of the transmission synchronous belt, the transmission connection block 463 and the synchronous connection block 442, when the transmission telescopic cross bar 450 moves, the transmission nozzle device 460 can be driven to move synchronously, that is, the lateral distance of the manipulator is shortened, making the transmission more stable, improving the transmission efficiency, and making the stamping production efficiency higher.

[0090] Compared with the prior art, the present invention has the following advantages:

[0091] The stamping production line of the present invention completes the stamping operation of large stamping parts by setting the stamping part feeding mechanism 100, the positioning and centering table mechanism 200, the stamping device 300 and the suspended transmission manipulator 400, thus replacing the traditional semi-automatic stamping method, improving the production efficiency and the stamping accuracy at the same time.

[0092] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
