Description

Technical Field

[0001] This invention relates to the field of integrated processing of sheet metal, and in particular to an automatic sheet metal cutting, punching, and bending device. Background Technology

[0002] Sheet metal production typically involves large areas, and in actual production applications, the sheets require a series of processes including cutting, punching, and bending. In existing technologies, cutting, punching, and bending are done on three separate machines. Sheet cutting requires manual assistance, and the cut sheets need to be manually transported. Punching also requires manual assistance, and the punched sheets need to be manually transported. Bending also requires manual assistance and manual transport and collection. Overall, a large amount of manpower is required, which is very inefficient and prone to errors when cutting, punching, and bending sheets in batches.

[0003] The existing published patent application, CN105710615A, is entitled "A Fully Automated Production Line for Sheet Cutting, Punching, and Bending." It discloses that a shearing robot 13 uses its suction cups to pick up sheet metal 19 and place it on a positioning worktable 2. The positioning worktable 2 first performs positioning in two planar dimensions. After positioning, the shearing robot 13 pushes the sheet metal 19 under a shearing machine 5, where it is sheared. However, using the shearing robot 13 to pick up and push the sheet metal makes it easy for it to fall off, and the accuracy of the sheet metal movement distance is insufficient. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cutting, punching, and bending device for sheet metal, which solves the problem of poor accuracy in sheet metal cutting distance.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention provides an automated sheet metal cutting, punching, and bending device, comprising a first robotic arm, a second robotic arm, a third robotic arm, a cutting machine, a punching machine, a bending machine, and a transfer rack. The cutting machine is equipped with a feeding mechanism at its feed end. The feeding mechanism includes a feeding table, a clamp, and a feeding cylinder. The first robotic arm is used to pick up the board and place it on the feeding table. The feeding cylinder is located on the feeding table, and the clamp is located at the drive end of the feeding cylinder. The clamp is used to hold the board. The feeding mechanism is configured such that when the first robotic arm delivers a sheet material above the feeding table, the feeding cylinder drives the clamp to a set position and pauses. Then, the clamp holds the sheet material, at which point the first robotic arm releases the sheet material, and most of the sheet material falls onto the feeding table. The feeding cylinder indirectly drives the sheet material to move a set distance until the sheet material moves to the cutting area of ​​the cutting machine, which is used to cut the sheet material. The second and third robotic arms are configured such that: the first robotic arm is used to adsorb the cut sheet material onto the transfer rack, the transfer rack and the punching machine are located within the adsorption range of the second robotic arm, the punching machine and the bending machine are located within the adsorption range of the third robotic arm, the second robotic arm is used to adsorb the cut sheet material into the punching area of ​​the punching machine, and the third robotic arm is used to adsorb the punched sheet material into the bending area of ​​the bending machine, and adsorb the bent sheet material into the stacking area.

[0006] To prevent the sheet material from touching the cutting area of ​​the cutting machine, the feeding table must be higher than the cutting area of ​​the cutting machine.

[0007] To enable the cut material to move, a receiving platform is further provided between the cutting machine and the transfer frame. The cutting machine is located between the receiving platform and the feeding platform. The receiving platform is used to collect the cut material and is lower than the cutting area of ​​the cutting machine.

[0008] To facilitate the alignment of the sheet metal, the system further includes a first alignment platform, a second alignment platform, and a third alignment platform. The first alignment platform, the second alignment platform, and the third alignment platform have the same structure. The first alignment platform is located within the adsorption range of the first robotic arm, the second alignment platform is located within the adsorption range of the second robotic arm, and the third alignment platform is located within the adsorption range of the third robotic arm.

[0009] To further illustrate the structure of the first alignment platform, the first alignment platform includes a support, a base plate, a first side plate, and a second side plate. The base plate is inclinedly disposed on the support, and the first side plate and the second side plate are disposed on the base plate. The base plate has a apex angle at its highest position and a bottom angle at its lowest position. The ends of the first side plate and the second side plate intersect at the bottom angle, and the position of the apex angle is higher than the position of the bottom angle.

[0010] To further reduce friction on the sides of the sheet metal, multiple first side wheels are rotatably mounted on the first side plate, and multiple second side wheels are rotatably mounted on the second side plate. Both the first side wheels and the second side wheels are located at the edge of the base plate.

[0011] To further reduce friction on the bottom surface of the sheet metal, multiple top posts and multiple top brushes are provided on the bottom plate. The top brushes are higher than the top posts and are used to support the galvanized layer on the sheet metal.

[0012] To temporarily store the cut boards, a temporary storage mechanism is provided below the transfer frame. The temporary storage mechanism includes a storage rack and a base. The storage rack is mounted on the base in a rotating and lifting manner.

[0013] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The automatic cutting, punching, and bending sheet metal device of the present invention, after the first robotic arm picks up the sheet metal and places it above the feeding table, the feeding cylinder drives the clamp to move a set distance, and then the clamp holds the sheet metal. The first robotic arm rotates and resets, and the feeding cylinder continues to drive the clamp to move until the clamp pushes the sheet metal into the cutting area of ​​the cutting machine. The feeding cylinder indirectly drives the sheet metal to move a precise distance, which is beneficial for the cutting machine. Furthermore, there is no concern about the sheet metal falling off during cutting, thus solving the problem of poor accuracy in sheet metal cutting distance. Attached Figure Description

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] like Figure 1 and Figure 2 and Figure 3 As shown, an automatic cutting, punching, and bending sheet metal device includes a first robotic arm 1, a second robotic arm 2, a third robotic arm 3, a cutting machine 4, a punching machine 5, a bending machine 6, and a transfer frame 7.

[0020] The feeding end of the cutting machine 4 is equipped with a feeding mechanism 8, which includes a feeding table 81, a clamp 82, and a feeding cylinder 83. The first robotic arm 1 is used to pick up the board and place it above the feeding table 81. The feeding table 81 is located on the feeding side of the cutting machine 4. The feeding cylinder 83 is located on the feeding table 81 and is fixed to the feeding table 81 by bolts. The clamp 82 is located on the driving end of the feeding cylinder 83 and is used to clamp the board.

[0021] The feeding mechanism 8 is configured such that when the first robotic arm 1 delivers a sheet material above the feeding table 81, the feeding cylinder 83 drives the clamp 82 to a set position and pauses. The clamp 82 holds the sheet material, at which point the first robotic arm 1 releases the sheet material, and most of the sheet material falls onto the feeding table 81. The feeding cylinder 83 indirectly drives the sheet material to move a set distance until the sheet material moves to the cutting area of ​​the cutting machine 4, where the cutting machine 4 is used to cut the sheet material.

[0022] After the last cut by the cutting machine 4, the clamp 82 releases the board, and the feeding cylinder 83 drives the clamp 82 to reset, and the remaining board falls below the cutting machine 4.

[0023] The second robotic arm 2 and the third robotic arm 3 are configured as follows: the first robotic arm 1 is used to adsorb the cut sheet material onto the transfer frame 7. The transfer frame 7 and the punching machine 5 are located within the adsorption range of the second robotic arm 2, and the punching machine 5 and the bending machine 6 are located within the adsorption range of the third robotic arm 3. The second robotic arm 2 is used to adsorb the cut sheet material into the punching area of ​​the punching machine 5, and the punching machine 5 punches holes in the cut sheet material. The third robotic arm 3 is used to adsorb the punched sheet material into the bending area of ​​the bending machine 6, and adsorb the bent sheet material into the stacking area. When the bending machine 6 bends the punched sheet material, the sheet material is adsorbed by the bending machine 6 during the bending process.

[0024] The feeding table 81 should be higher than the cutting area of ​​the cutting machine 4, so that when the feeding cylinder 83 indirectly drives the board, the end of the board will not abut against the outer wall of the cutting area of ​​the cutting machine 4, which is beneficial to the movement of the board.

[0025] A receiving platform 10 is provided between the cutting machine 4 and the transfer frame 7. The cutting machine 4 is located between the receiving platform 10 and the feeding platform 81. The receiving platform 10 is used to collect the cut boards. The receiving platform 10 is lower than the cutting area of ​​the cutting machine 4. The receiving platform 10 is located on the side of the output end of the cutting machine 4. When the feeding cylinder 83 indirectly drives the board to move, the board moves to the receiving platform 10. After the cutting machine 4 cuts the board, the cut board falls onto the receiving platform 10.

[0026] It also includes a first alignment platform 11, a second alignment platform 12, and a third alignment platform 13. The first alignment platform 11, second alignment platform 12, and third alignment platform 13 have identical structures. The first alignment platform 11 is located within the adsorption range of the first robotic arm 1, the second alignment platform 12 is located within the adsorption range of the second robotic arm 2, and the third alignment platform 13 is located within the adsorption range of the third robotic arm 3. In the initial state, the first robotic arm 1 adsorbs the sheet material onto the first alignment platform 11 for alignment. Then, the first robotic arm 1 adsorbs the aligned sheet material above the feeding table 81, so that the sheet material... Keeping the material horizontal, the second robot 2 picks up the cut sheet from the transfer rack 7 and places it onto the second alignment platform 12, aligning the cut sheet. The second robot 2 then picks up the cut sheet onto the punching area of ​​the punching machine 5. After the sheet is punched, the third robot 3 picks up the punched sheet onto the third alignment platform 13 for alignment. The third robot 3 then picks up the aligned sheet onto the bending area of ​​the bending machine 6. After bending, the third robot 3 picks up the bent sheet onto the stacking area.

[0027] A temporary storage mechanism 9 is provided below the transfer rack 7. The transfer rack 7 has a gap 70. The temporary storage mechanism 9 includes a storage rack 91 and a base 92. The storage rack 91 is mounted on the base 92 in a rotating and lifting manner. The temporary storage mechanism 9 is located below the gap 70. When the cut board needs to be temporarily stored, the storage rack 91 rises up to lift the cut board. Then the storage rack 91 rotates 90°. Finally, the storage rack 91 retracts back below the gap 70. Alternatively, the first robotic arm 1 can directly place the cut board on the storage rack 91.

[0028] like Figure 4 and Figure 5 As shown, the first alignment platform 11 includes a bracket 111, a base plate 112, a first side plate 113, and a second side plate 114. The base plate 112 is inclinedly mounted on the bracket 111 and is fixed to the bracket 111 by bolts. The first side plate 113 and the second side plate 114 are mounted on the base plate 112 and are fixed to the base plate 112 by bolts. The base plate 112 has a apex angle 115 at its highest position and a bottom angle 116 at its lowest position. The ends of the first side plate 113 and the second side plate 114 intersect at the bottom angle 116. The position of the apex angle 115 is higher than the position of the bottom angle 116. The first side plate 113 and the second side plate 114 are used to align the two edges of the plate, so that the plate can be positioned through alignment.

[0029] Multiple first side wheels 117 are rotatably arranged on the first side plate 113, and multiple second side wheels 118 are rotatably arranged on the second side plate 114. The first side wheels 117 and the second side wheels 118 are both located at the edge of the bottom plate 112. When the first robot arm 1 picks up the plate and puts it into the bottom plate 112, the two adjacent sides of the plate abut against the first side wheels 117 and the second side wheels 118 respectively, and the lower end of the plate abuts against the intersection of the ends of the first side plate 113 and the second side plate 114.

[0030] Multiple top posts 119 and multiple top brushes 110 are provided on the base plate 112. The multiple top posts 119 and multiple top brushes 110 are evenly arranged and fixed to the base plate 112 by bolts. The top brushes 110 are higher than the top posts 119. The top brushes are used to support the galvanized layer on the plate. In this example, the plate is a galvanized plate. The first robot 1 places the plate on the multiple evenly arranged top brushes 110. At the same time, the plate moves downward on the top brushes 110. The top brushes 110 can reduce the wear on the zinc layer on the plate. The plate bends the top brushes 110 during the movement. Finally, the plate overlaps the multiple top posts 119. At this time, the lower end of the plate abuts against the intersection of the ends of the first side plate 113 and the second side plate 114.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
