Description

Technical Field

[0001] The utility model relates to the field of sewing processing equipment, in particular to a multi-station template sewing production line. Background Art

[0002] A template machine, also known as a template sewing machine, refers to a sewing processing equipment that uses a computer-controlled machine with a higher degree of automation to replace the original manual operation. It solves the problems of labor shortage and skill defects of industrial workers, and fully automatically completes garment sewing, promoting the streamline of the garment template process.

[0003] However, most of the existing template machines still complete the loading and unloading operations of the template manually. Since the loading and unloading positions of most template machines are at two different positions on the workbench of the template machine, the template machine needs to be equipped with a worker to be responsible for operating the machine and the loading and unloading operations of the template. However, when using this template machine usage mode to carry out the production and processing of garments, it will result in a relatively high labor cost; if the number of workers configured for the template machine production in the factory is small, when using multiple template machines for large-scale garment production and processing, there will be a situation where a worker operates multiple template machines alone and the worker will move during the loading and unloading operations. This will undoubtedly pose a huge challenge to the operation difficulty and physical labor of the worker. Moreover, too many manual operations during the production process of the template machine will have a certain impact on the production speed and quality of the template machine. The progress of the template machine towards streamline and intelligent development is still slow. Summary of the Utility Model

Detailed implementation mode

[0035] The utility model discloses a multi-station template sewing production line. As Figures 1 - 3 shown in combination, the production line includes two template units 1. The template unit 1 includes two processing mechanisms 2 and a workbench 3. The two processing mechanisms 2 are respectively arranged on both sides of the workbench 3. A positioning device 4 is arranged on the workbench 3 between the two processing mechanisms 2. Positioning areas 5 are arranged on the surfaces of the workbench 3 outside both sides of the positioning device 4. First transfer tracks 6 are arranged on the surfaces of the workbench 3 outside the longitudinal and transverse directions of the positioning area 5. A second transfer track 7 is arranged on the surface of the workbench 3 in the longitudinal direction where the first transfer track 6 is not located. The moving paths of all the first transfer tracks 6, the second transfer track 7, and the feeding device 8 in the processing mechanism 2 in the transverse direction together form a circular transfer path 9 on the surface of the workbench 3. Transfer mechanisms 10 are arranged in the workbench 3 below the first transfer track 6 and the second transfer track 7. A material placing mechanism 11 is arranged between the two template units 1. The material placing mechanism 11 includes a material placing table 12, a robotic arm 13 outside the material placing table 12, and a material picking device 14. The material picking device 14 is connected to the output end of the robotic arm 13 and moves towards the positioning area 5 and the material placing table 12 under the drive of the robotic arm 13.

[0036] The pipeline includes two template units 1, and there are also two processing mechanisms 2 capable of sewing processing in the template units 1, and the sewing processes between these workstations do not affect each other; the moving paths of the two first transfer tracks 6, the second transfer track 7, and the feeding device 8 in the lateral direction are docked with each other at the positions where the longitudinal and lateral directions of the transfer path 9 are converted.

[0037] When the pipeline is working: The worker operates at a certain position outside the material placing table 12, and places the new cut pieces into the template on the material placing table 12. Subsequently, the material taking device 14 is driven by the robotic arm 13 with multiple direction and position adjustment functions to transfer the template with the new cut pieces placed at the rear end of the material placing table 12 to the positioning area 5 on the two template units 1, which not only realizes the automatic feeding operation of the template, but also can achieve the purpose of delivering the template to different workstations through the structure of the robotic arm 13 cooperating with the material taking device 14. After receiving the template, the workstation can perform the transfer of the template.

[0038] Then, the positioning device 4 can position the template transferred by the robotic arm 13 to the positioning area 5 to ensure that the template in the positioning area 5 does not have a position deviation, so that it can be accurately taken away from the positioning area 5 by the transfer mechanism 10 provided in the first transfer track 6 outside the longitudinal direction of the positioning area 5, thereby accurately transferring the template to the feeding device 8; at the same time, the transfer mechanism 10 provided in the first transfer track 6 outside the longitudinal direction of the positioning area 5 moves its working end towards the positioning area 5 and forms a traction with the template in the positioning area 5. After the working end of the positioning device 4 disengages from the template in the positioning area 5, the transfer mechanism 10 provided in the first transfer track 6 outside the longitudinal direction of the positioning area 5 pulls the template and moves along the first transfer track 6 on the surface outside the longitudinal direction of the positioning area 5 to deliver the template to the position of the workbench 3 near the end of the feeding device 8; then, after the feeding device 8 presses the template, it drives the template to move in the lateral direction of the workbench 3, that is, to move in the lateral direction of the transfer path 9. After reaching the position in a straight line with the sewing machine head in the processing mechanism 2, the template is moved under the sewing machine head in the processing mechanism 2, and the sewing machine head sews the material in the template. After processing the material, the template will be driven back onto the transfer path 9 again, and the feeding device 8 continues to drive the template to move in the lateral direction of the transfer path 9 until it reaches the end of the second transfer track 7 docked with the feeding device 8. The transfer mechanism 10 on the second transfer track 7 transfers the template to the end of the first transfer track 6 outside the transverse direction of the positioning area 5, and the template transferred to the end of the first transfer track 6 will be transferred to the positioning area 5 by the transfer mechanism 10 provided at the first transfer track 6 outside the transverse direction of the positioning area 5, completing the automatic transfer of the template before and after sewing processing.

[0039] Finally, the template with the sewn material in the positioning area 5 is pulled out of the positioning area 5 by the material taking device 14 and finally transferred to the front of the worker through the material placing table 12, thus realizing the automatic blanking operation of the template; similarly, through the structure of the robot arm 13 cooperating with the material taking device 14, the templates in the positioning areas 5 at multiple workstations can be transferred to the material placing table 12, and the templates with the sewn material in the positioning area 5 can be removed in time for the next cycle of sewing processing.

[0040] To sum up, this production line can achieve independent sewing processing at multiple workstations. The normal operation of one processing unit is not affected even if another processing unit fails, which improves the ability of the template machine to meet the requirements of large - batch processing production and can meet the usage requirements of different production scales. It can also fully automatically realize the feeding of the template, the transmission of the template before and after sewing processing, and the blanking operation of the template. Workers only need to place materials at the position outside the material placing mechanism 11 without moving around. One worker can complete the processing operations of the template machine production line with multiple processing workstations at the same time. The degree of automation is high, which can maximize the reduction of workers and save production costs.

[0041] Specifically, as Figure 4 shown, the positioning device 4 includes a first bracket 15 and a positioning component 16. The bottom end of the first bracket 15 is connected to the workbench 3 outside the positioning area 5. The positioning component 16 is arranged on both sides of the top end of the first bracket 15 and above the positioning area 5. The positioning component 16 includes a first cylinder 17, a positioning plate 18 and a first convex column 19. The first cylinder 17 is fixedly connected to both sides of the top end of the first bracket 15 through a connecting frame 20. The output end of the first cylinder 17 is fixedly connected with a positioning plate 18. The bottom surfaces at both ends in the length direction of the positioning plate 18 are connected with first convex columns 19.

[0042] Among them, the first cylinder 17 drives the positioning plate 18 to move up and down, and the first convex columns 19 on the positioning plate 18 will also move up and down with the positioning plate 18. After the positioning plate 18 moves down and presses on the surface of the template, the first convex columns 19 will also insert into the holes on the edge of the template, so as to position the template in the positioning area 5 and prevent the displacement of the template when the transmission mechanism 10 arranged in the first transmission track 6 outside the longitudinal direction of the positioning area 5 pulls the template, which may cause problems.

[0043] It should be further noted that, as Figure 4 and Figure 5As shown in combination, the first bracket 15 includes a first connecting column 21 and a top beam 22. The top beam 22 is connected to the top end of the first connecting column 21. The ends in the length direction of the top beam 22 are located above the positioning area 5. The first cylinder 17 is fixedly connected to the end in the length direction of the top beam 22 through a connecting frame 20. At least two corners at the bottom and top ends of the first connecting column 21 are connected to a first connecting member 23. The first connecting member 23 is provided with at least one first waist-shaped hole 24 in both the horizontal and vertical directions. The surface of the first connecting column 21, the surface of the workbench 3, and the bottom surface of the top beam 22 are all provided with first connecting grooves 25. Both ends in the length direction of the top beam 22 are provided with second connecting members 26. The second connecting members 26 are connected to the first connecting grooves 25 located on the top beam 22. The second connecting members 26 are provided with at least one second waist-shaped hole 27 in both the horizontal and vertical directions. One end of the connecting frame 20 is connected through the second waist-shaped hole 27 of the second connecting member 26, and the first cylinder 17 is connected to the other end of the connecting frame 20.

[0044] Among them, both ends in the length direction of the top beam 22 are located above the positioning area 5. By adjusting the first cylinders 17 connected to both ends in the length direction of the top beam 22, the number of first cylinders 17 on the template unit 1 can be adjusted, and the production scale of the template unit 1 for single-station work or double-station work can be realized, so as to meet the sewing processing requirements of different scales.

[0045] Secondly, by introducing connecting components into the first waist-shaped holes 24 in the horizontal and vertical directions on the first connecting member 23 at the bottom end of the first connecting column 21 respectively, the connection between the first positioning connection and the bottom end of the first connecting column 21 can be realized, and the connection between the first connecting column 21 and the workbench 3 can be realized; the design of the first waist-shaped hole 24 can adjust the connection position of the bottom end of the first connecting column 21 on the first connecting member 23, so as to adjust the height position of the first connecting column 21 relative to the surface of the workbench 3, and further adjust the positions of the first convex column 19 and the positioning plate 18 above the positioning area 5 to meet the positioning requirements of templates with different thickness specifications; the position adjustment of the first connecting column 21 in the horizontal direction of the bracket can make the positions of the first convex column 19 and the positioning plate 18 be adjusted adaptively when the positioning device 4 fixes templates with different width specifications.

[0046] Similarly, by introducing a connecting component into the first kidney-shaped hole 24 of the second connecting member 26 located at the top of the first connecting column 21, the connection between the second connecting member 26 and the top of the first connecting column 21 and the connection between the first connecting column 21 and the top beam 22 can be achieved; by changing the connection position of the connecting member on the first connection groove 25 of the top beam 22, the lengths of the top beams 22 on both sides of the top of the first connecting column 21 can be adjusted, thereby changing the positions of the first convex column 19 and the positioning plate 18 above the positioning area 5 to meet the positioning requirements of templates with different width specifications; when the second connecting member 26 is connected to the top of the first connecting column 21, by adjusting the connection position of the second connecting member 26 on the top of the first connecting column 21, the height position of the top beam 22 can be adjusted, and further the positions of the first convex column 19 and the positioning plate 18 above the positioning area 5 can be adjusted to meet the positioning requirements of templates with different thickness specifications.

[0047] In addition, by introducing a connecting component into the second kidney-shaped hole 27 in the horizontal part of the second connecting member 26 and connecting it to the first connection groove 25 located at the end of the top beam 22 in the length direction outside the second kidney-shaped hole 27, the connection between the second connecting member 26 and the top beam 22 is achieved, and at the same time, the second connecting member 26 provides a position for the detachable connection of the connecting frame 20.

[0048] It should be further noted that, as Figures 5 - 7 shown in combination, the connecting frame 20 is composed of a first connecting plate 28, an L-shaped second connecting plate 29, and a third connecting plate 30. The two ends of the first connecting plate 28 in the length direction are respectively provided with a first mating hole 31 and a second mating hole 32. The first mating hole 31 is opposite to the second kidney-shaped hole 27 in the vertical direction of the second connecting member 26. The second connecting plate 29 is connected to the other end of the first connecting plate 28 in the length direction. One end of the second connecting plate 29 is provided with a plurality of third kidney-shaped holes 33 opposite to the second mating hole 32. The middle of the other end of the second connecting plate 29 is provided with a plurality of fourth kidney-shaped holes 34. Third mating holes 35 are provided at the four corners of the end of the second connecting plate 29 where the fourth kidney-shaped holes 34 are located. The middle of the third connecting plate 30 is provided with a plurality of fourth mating holes 36 opposite to the fourth kidney-shaped holes 34. The non-output end part of the first air cylinder 17 is connected outside the fourth mating hole 36. Fifth kidney-shaped holes 37 opposite to the third mating holes 35 are provided at the four corners of the third connecting plate 30.

[0049] Among them, a connecting component is introduced into the second waist-shaped hole 27 in the horizontal direction of the second connecting member 26 and connected to the first connecting groove 25 at the end of the top beam 22 in the length direction through the connecting component, so as to realize the connection between the second connecting member 26 and the top beam 22; the connecting component is respectively introduced into the first through hole and the second waist-shaped hole 27 in the vertical direction of the second connecting member 26 to realize the connection between the first connecting plate 28 and the second connecting member 26. When the first connecting plate 28 is at different positions on the second waist-shaped hole 27 in the vertical direction of the second connecting member 26, the height position of the first connecting plate 28 will also be different, and the overall height of the connecting frame 20 above the positioning area 5 is variable, so as to realize the position adjustment of the first convex column 19 and the positioning plate 18 above the positioning area 5, so as to meet the positioning needs of templates with different thickness specifications.

[0050] Then, a connecting component is introduced into the third waist-shaped hole 33 and the second through hole of the second connecting plate 29, and the connection between the second connecting plate 29 and the first connecting plate 28 can be realized; and the positions where the connecting component is connected to the third waist-shaped hole 33 are different, and the height positions of the second connecting plate 29 will also be different. When the position where the connecting component is connected to the third waist-shaped hole 33 changes, the positions of the first convex column 19 and the positioning plate 18 above the positioning area 5 will also change, further adapting to the positioning needs of templates with different thickness specifications.

[0051] In addition, a connecting component is respectively loaded into the fourth waist-shaped hole 34 and the fourth through hole, and the third through hole and the fifth waist-shaped hole 37, and the connection between the second connecting plate 29, the third connecting plate 30 and the first air cylinder 17 can be realized. By changing the connection positions of the connecting component in the fourth waist-shaped hole 34 and the fifth waist-shaped hole 37, the positions of the first convex column 19 and the positioning plate 18 above the loading area can be changed, specifically, the position adjustment in the direction parallel to the horizontal plane, so as to meet the requirements when positioning templates with different width specifications.

[0052] Specifically, as Figures 8 - 10 As shown in combination, the transmission mechanism 10 includes an electric guide rail 38, a fixing plate 39 and a second air cylinder 40. The electric guide rail 38 is fixed on the workbench 3 below the transmission track. The fixing plate 39 is fixedly connected to the output end of the electric guide rail 38. The second air cylinder 40 is fixedly connected to the end of the fixing plate 39. The output end of the second air cylinder 40 is connected with a positioning member 41. The cross-sectional shape of the fixing plate 39 is V-shaped. The non-bifurcated end of the fixing plate 39 is fixedly connected to the output end of the electric guide rail 38. Second air cylinders 40 are fixedly connected to both sides of the bifurcated end of the fixing plate 39.

[0053] When the template with the newly cut piece is moved to the positioning area 5 and pressed by the positioning device 4, the positioning member 41 carried by the conveying mechanism 10 provided on the first conveying track 6 outside the longitudinal direction of the positioning area 5 will penetrate into the holes on the surface of the template to form a connection with the template. Then, the electric guide rail 38 in the conveying mechanism 10 is activated, and the template is driven by the positioning member 41 to move on the first conveying track 6 outside the longitudinal direction of the positioning area 5 until the template moves to one end of the length direction of the feeding device 8. Then, the second cylinder 40 carried by the conveying mechanism 10 on the first conveying track 6 outside the longitudinal direction of the positioning area 5 drives the positioning member 41 to move downward, causing the positioning member 41 to disengage from the template. After the positioning member 41 disengages from the template, the conveying mechanism 10 provided in the first conveying track 6 in the longitudinal direction of the workbench 3, which is equipped with the second cylinder 40 and the positioning member 41, resets;

[0054] Then, the output end of the feeding device 8 presses the template and drives the template to move in the transverse direction of the workbench 3. After the template is driven by the feeding device 8 to move to a position in the same straight line direction as the sewing head, it then moves in the longitudinal direction of the workbench 3 to the position below the sewing head. The sewing head sews the material in the template. After the sewing process is completed, the template moves to a position away from the sewing head through longitudinal movement, and then continues to move in the transverse direction of the workbench 3 under the drive of the feeding device 8;

[0055] When the template moves to the other end of the length direction of the feeding device 8, the positioning member 41 carried by the conveying mechanism 10 provided on the second conveying track 7 penetrates into the holes on its surface to connect the template. The output end on the feeding device 8 disengages from the template and moves back to the end of the length direction of the feeding device 8 away from the template side; the electric guide rail 38 carried by the conveying mechanism 10 on the second conveying track 7 starts to work, and the template is driven by the positioning member 41 to move on the second conveying track 7, and the template is transported to one end of the first conveying track 6 outside the transverse direction of the positioning area 5. The second cylinder 40 carried by the conveying mechanism 10 on the second conveying track 7 drives the positioning member 41 to move downward to disengage from the template, and the conveying mechanism 10 on the second conveying track 7 drives the second cylinder 40 and the positioning member 41 to move back to a position close to the end of the length direction of the feeding device 8 to reset;

[0056] Finally, the transfer mechanism 10 provided on the first transfer track 6 outside the lateral direction of the positioning area 5 drives the template to move by the second cylinder 40 it is equipped with. The second cylinder 40 drives the positioning member 41 to move upward, so that the positioning member 41 penetrates into the through-hole on the template to realize the connection with the template. The transfer mechanism 10 of the first transfer track 6 provided outside the lateral direction of the positioning area 5 drives the template to move, and moves the template from one end of the first transfer track 6 outside the lateral direction of the positioning area 5 to the positioning area 5, thus completing the automatic transfer of the template along the transfer path 9.

[0057] Moreover, the fixing plates 39 used for fixing the second cylinders 40 in both the transfer mechanism 10 on the first transfer track 6 outside the longitudinal direction of the positioning area 5 and the transfer mechanism 10 on the second transfer track 7 are both V-shaped. The second cylinders 40 on both sides of the forked end of the fixing plate 39 can drive the positioning member 41 to move up and down, so as to realize the operation of inserting the positioning member 41 into or removing it from the through-hole on the template, and further realize the connection or disconnection between the transfer mechanism 10 and the template. By inserting the positioning members 41 connected to the second cylinders 40 into the through-holes on the template, the position of the template can be kept more stable when being pulled by these two transfer mechanisms 10 on the surface of the workbench 3, avoiding the situation that the material cannot be processed or transferred normally due to the position deviation of the template.

[0058] It should be further noted that, as Figures 8 - 10 shown in combination, the positioning member 41 includes a positioning pin 42, and the positioning pin 42 is fixedly connected to the output end of the second cylinder 40. The number of positioning pins 42 connected to the output end of the second cylinder 40 is at least one.

[0059] In the transfer mechanism 10 on the first transfer track 6 outside the longitudinal direction of the positioning area 5 and the transfer mechanism 10 on the second transfer track 7, when the positioning pins 42 connected to the two second cylinders 40 penetrate into the holes on the template, the position of the template can be kept more stable when being pulled by the transfer mechanism 10 and moving on the first transfer track 6 or the second transfer track 7 outside the longitudinal direction of the positioning area 5;

[0060] The transfer mechanism 10 on the first transfer track 6 located outside the positioning area 5 in the longitudinal direction has at least two positioning pins 42 connected to the output end of the second cylinder 40. When the second cylinder 40 on the transfer mechanism 10 of the first transfer track 6 moves to the positioning area 5 or the blanking position, the positions of the positioning pins 42 are individually corresponding to the positioning pins 42 on the transfer mechanisms 10 on both sides of the workbench 3 in the longitudinal direction of the workbench 3. Thus, after the template reaches the blanking position, the transfer mechanism 10 on the first transfer track 6 outside the longitudinal direction of the positioning area 5 and the two transfer mechanisms 10 on the second transfer track 7, the positioning pins 42 they carry disengage from the template. The transfer mechanism 10 on the first transfer track 6 located outside the longitudinal direction of the positioning area 5, the positions of the positioning pins 42 it carries and the holes on the template are on the same straight line. After the transfer mechanism 10 outside the transverse direction of the positioning area 5 moves to one end of the first transfer track 6 outside the transverse direction of the positioning area 5, the positioning pin 42 can be inserted into the through hole on the template, so that not only can the transfer mechanism 10 outside the transverse direction of the positioning area 5 be connected to the template through the positioning pin 42, but also the transfer of the template from the longitudinal direction to the transverse direction can be realized.

[0061] It should be further noted that, as Figure 8 shown, the positioning member 41 further includes a fixing block 43. One end of the fixing block 43 is connected to the driving end of the second cylinder 40, and the positioning pin 42 is connected to the end of the fixing block 43 away from the second cylinder 40.

[0062] Among them, since the positioning pins 42 carried by the transfer mechanism 10 outside the longitudinal direction of the positioning area 5 need to move to the positioning area 5 and be connected to the template in the positioning area 5, and the fixing plate 39 carried by the transfer mechanism 10 outside the transverse direction of the positioning area 5 is set in a position that will hinder the movement of the second cylinder 40 on the transfer mechanism 10 outside the longitudinal direction of the positioning area 5, making the positioning pins 42 carried by the transfer mechanism 10 outside the longitudinal direction of the positioning area 5 unable to move to the positioning area 5; therefore, the setting of the fixing block 43 can extend the connection part between the second cylinder 40 outside the longitudinal direction of the positioning area 5 and the positioning pins 42, so that the second cylinder 40 outside the longitudinal direction of the positioning area 5 can avoid the position of the fixing plate 39 on the transfer mechanism 10 outside the transverse direction of the positioning area 5 and move its positioning pins 42 to the positioning area 5 to form a connection with the template, avoiding interference between the two transfer mechanisms 10 outside the longitudinal and transverse directions of the positioning area 5.

[0063] Specifically, as Figures 11 - 14As shown in combination, a feeding channel 44 is provided inside the top of the blanking table 12. Two guide rails 45 are provided on the wall surfaces of the blanking table 12 on the left and right sides of the feeding channel 44. The two guide rails 45 on the same side wall surface of the blanking table 12 are distributed at the upper and lower ends of the wall surface of the blanking table 12. The guide rails 45 are fitted with sliders 46. The sliders 46 at the same height inside the feeding channel 44 are connected with a blanking plate 47 through a fourth connecting plate 64. A third air cylinder 48 is provided on the surface in the middle of the feeding channel 44. The output end of the third air cylinder 48 is connected with the blanking plate 47 at the lower position inside the feeding channel 44. Connecting seats 49 are provided on the wall surfaces on the left and right sides of the blanking table 12. A connecting shaft 50 is connected between the two connecting seats 49. A part of the connecting shaft 50 located outside the connecting seat 49 is fitted with a gear 51. A rack 52 meshing with the gear 51 is fixedly connected to the surface of the fourth connecting plate 64 close to the gear 51 side. A second support 53 extending into the space above the blanking table 12 is provided in the middle of the blanking table 12. A plurality of fifth fitting holes 54 are provided at the top end of the second support 53. A hook 55 with its non-hooking end inserted into the fifth fitting hole 54 is connected to the second support 53.

[0064] Among them, the third air cylinder 48 is connected to the blanking plate 47 at the lower position inside the feeding channel 44 through its output end and moves inside the feeding channel 44. At this time, the kinetic energy output by the third air cylinder 48 will be transmitted to the gear 51 through the rack 52 connected to the blanking plate 47 at the lower position inside the feeding channel 44. Since there is a meshing relationship between the gear 51 and the rack 52 connected to the blanking plate 47 at the higher position inside the feeding channel 44, the kinetic energy will be transmitted to the blanking plate 47 at the higher position inside the feeding channel 44 through the gear 51, causing the blanking plate 47 at the higher position inside the feeding channel 44 to move inside the feeding channel 44, achieving the effect of driving the two blanking plates 47 simultaneously; and since the directions of movement of the racks 52 meshing with the upper and lower sides of the gear 51 are opposite when the gear 51 rotates, the moving directions of the two blanking plates 47 at different heights inside the feeding channel 44 are opposite. Through their reciprocating movement inside the feeding channel 44, the effect of continuously conveying the template with the newly placed cut pieces to the picking device 14 and transferring the template taken from the blanking position of the station by the picking device 14 to the position where the worker is located can be achieved.

[0065] In addition, when a new cut piece is made for the template placed on the stock plate 47 behind the feeding channel 44 or the processed material is taken out, the upper part of the template needs to be turned up. When turning up the frame part of the upper layer of the template, if the frame part of the upper layer of the template is not fixed, the upper part of the template is likely to cover the surface of the lower part of the template again, affecting the operation when making a new cut piece for the template or taking out the processed material. Therefore, when turning up the frame part of the upper layer of the template through the hook 55, the hook 55 can be used to hook the frame part of the upper layer of the template, thereby fixing the position of the frame part of the upper layer of the template, and further facilitating the operation of the worker when making a new cut piece for the template or taking out the processed material. In addition, by fitting the non-hooking end of the hook 55 into the fifth fitting holes 54 at different positions at the top of the bracket, the hook 55 can be adapted to the frame part in the upper layer of templates of different specifications and sizes, so that after being turned up, it can be hooked on the hook 55 for position fixing.

[0066] Specifically, as Figures 14 - 16 As shown in combination, the material taking device 14 includes a mounting frame 56 and a suction cup 58. The mounting frame 56 is arranged at the output end of the robotic arm 13. The bottom end of the mounting frame 56 is several second connecting columns 57 arranged in an array in the same direction. Both ends of the second connecting column 57 in the length direction are connected with a suction cup 58 through a third connecting piece 65. A second connecting groove 59 distributed along the length direction of the second connecting column 57 is arranged on the surface of the second connecting column 57. One end of the third connecting piece 65 is provided with a connecting hole 60 facing the second connecting groove 59, and the suction cup 58 is detachably connected to the other end of the third connecting piece 65.

[0067] Among them, several suction cups 58 are arranged on the mounting frame 56, which can adsorb at multiple positions of the template when pulling the template, thereby increasing the connection tightness of the material taking device 14 to the template and avoiding the situation that the template detaches during the process of the robotic arm 13 driving the material taking device 14 to move. The range of template specifications and sizes that the material taking device 14 can pull can also be adjusted by adjusting the number of the second connecting columns 57 connected to the bottom end of the mounting frame 56, so that the material taking device 14 can meet the requirements for connection tightness when pulling templates of different specifications and sizes.

[0068] In addition, the third connecting piece 65 is connected to the second connecting column 57 by introducing a connecting component into the connecting hole 60 and the second connecting groove 59. By adjusting the position corresponding to the second connecting groove 59 of the connecting hole 60, the position of the third connecting piece 65 connected to the second connecting column 57 in the length direction can be adjusted. After the position of the suction cup 58 changes in the length direction of the second connecting column 57, the range of template specifications and sizes that the material taking device 14 can pull is further expanded.

[0069] It should be further noted that, asFigure 17 As shown, a number of sixth mating holes 61 are arranged in a matrix on the surface of the blanking plate 47. At least two of the sixth mating holes 61 are fitted with second convex posts 62, and the central axes of at least two of the second convex posts 62 are in the same plane.

[0070] Among them, when the template is placed on the surface of the blanking plate 47, the second convex post 62 can penetrate into the holes on the template, thereby fixing the position of the template and preventing the position of the template from shifting when the blanking plate 47 moves, ensuring that the material taking device 14 can accurately connect with the template to pull the template; by fitting the second convex post 62 into the sixth mating holes 61 at different positions on the surface of the blanking plate 47, the second convex post 62 can penetrate into the holes on templates of different sizes and specifications, ensuring that templates of different sizes and specifications can be fixed when placed on the surface of the blanking plate 47.

[0071] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
