[0045] Each placement groove 711 of the welding jig 71 can be arranged according to actual conditions, the thorn sheet 101 is carried into the placement groove 711 by the first robot 41, and the round steel 102 is moved to the welding jig 71 by the second robot 42, so that the feeding operation is realized without manual carrying, the production efficiency of the thorn wire can be effectively improved, the placement position of the thorn sheet 101 can be accurately and stably ensured, and the problems of large error and poor stability of product quality caused by manual operation can be avoided. The round steel 102 and the thorn sheet 101 are welded by the welding robot 44, manual welding is not required, the welding efficiency is high, the stability of the welding quality can be ensured, and then the stability of the final product quality can be ensured.

[0046] As shown in Figure 4 The punching device 1 includes a coiling machine 12, a roller 13 and a punching machine 11, the coiling machine 12 is coiled with the steel sheet 14, the roller 13 is located between the coiling machine 12 and the punching machine 11, one end of the steel sheet 14 passes through the roller 13 and can move to one side of the punching machine 11 under the driving action of the roller 13, the punching machine 11 is provided with a punching die 111, the punching machine 11 can cut the steel sheet 14 with a preset length, and punch the cut steel sheet 14 to form the thorn sheet 101 with the bending triangular structure 1011 at both ends and the arc-shaped structure 1012 in the middle as shown in Figure 1 and Figure 2

[0047] ​With the driving of the roller 13, the steel sheet 14 wound to the coiling machine 12 rotates and releases the steel sheet 14, so that the end of the steel sheet 14 moves to the punching machine 11, and the specific structure of the coiling machine 12 is not limited, which can be set as a rotating wheel, and the steel sheet 14 is wound to the outer periphery of the rotating wheel, that is, during the punching process, the steel sheet 14 does not need to be manually transported, and through the driving of the roller 13 and the cooperation of the punching machine 11, the automatic punching forming of the barb sheet 101 can be realized without manual operation, thereby effectively improving the production efficiency while avoiding the unstable quality of the barb sheet 101 due to manual operation errors or mistakes.

[0048] In this embodiment, the specification of the steel sheet 14 can be set according to the demand of the barb sheet 101 of the actual barb wire, such as a steel sheet 14 with a width of 12 mm and a thickness of 1 mm can be punched, of course, the specific structure and size of the barb sheet 101 can be set according to actual needs, which is not limited here.

[0049] And in this embodiment, the punching equipment 1 is not limited, such as the punching equipment 1 can directly cut and punch the steel sheet 14 to form the bent triangular structure 1011, the arch structure 1012 and the welding hole 1013, or the punching equipment 1 includes two or more punching stations, such as the first punching station is closest to the roller 13, the first punching station is used to cut the steel sheet 14 with a predetermined length, the second punching station is used to punch the cut steel sheet 14 to form a bent triangular structure, and the third punching station is used to punch the arch structure 1012 and the welding hole 1013. The second punching station can be located between the first and third punching stations, or the third punching station can be located between the first and second punching stations, and the movement of the steel sheet 14 in the punching station can be moved by a robot or pushed by a pusher 10. The degree of automation is high, no manual operation is required, the production efficiency is effectively improved, and the product quality stability is ensured.

[0050] The production of the barb sheet 101 is continuous, and each punching station can work simultaneously to punch different steel sheets 14 to ensure production efficiency. The finally formed barb sheet 101 can be moved to the discharging area of the punching equipment 1 by a robot or a pusher 10 and moved to the visual detection equipment 2.

[0051] The punching die 111 is a special composite die, and the punching machine 11 is controlled by an automatic punching machine to realize the integrated forming process of the barb sheet 101 from the coiled material to the finished product, and the cutting and punching are performed simultaneously, and the automatic process of feeding and discharging is realized by the roller 13 and the pusher 10.

[0052] For example, Figure 3As shown, a buffer device 3 is further arranged on the downstream side of the visual inspection device 2, and is used to store the thorn pieces 101 that pass the visual inspection device 2. The first robot 41 is specifically used to move the thorn pieces 101 in the buffer device 3 to the placement slot 711 of the welding jig 71. Of course, in the present embodiment, the buffer device 3 can also not be arranged, and when the visual inspection device 2 detects that the thorn piece 101 is qualified, the first robot 41 can directly move the qualified thorn piece 101 to the welding jig 71. The arrangement of the buffer device 3 can store or call the excess thorn pieces 101, so that when the upstream thorn piece 101 production is greater than or less than the downstream thorn piece 101 usage, the excess thorn pieces 101 can be buffered and placed or extracted for use, so as to integrate the production rhythm, ensure the continuity of production, and further ensure the production efficiency.

[0053] Specifically, in the present embodiment, the specific structure of the buffer device 3 is not limited, for example, the buffer device 3 is provided with at least two buffer portions, and the buffer portions are provided with through accommodating grooves in the length direction, the accommodating grooves are used to accommodate a plurality of thorn pieces 101, and the buffer portions can move between the feeding side and the discharging side of the buffer device 3. The feeding side refers to the side facing the visual inspection device 2, and the discharging side refers to the side facing the welding jig 71. Specifically, in the production state, the buffer portion in which the thorn pieces 101 are placed moves to the discharging side, and the thorn pieces 101 in the buffer portion are moved to the welding jig 71 by the first robot 41. At the same time, another buffer portion is located on the feeding side, and is used to receive the thorn pieces 101 that pass the visual inspection device 2.

[0054] The at least two buffer portions store the thorn pieces 101 in batches, so as to temporarily store the excess products or call the temporarily stored products, and buffer and control the production rhythm.

[0055] The buffer device 3 is further provided with a driving portion, and the driving portion is used to drive the buffer portions to move between the feeding side and the discharging side. Figure 5 As shown, the buffer device 3 further includes a guide rail 31, a grouping cylinder 32 and a second laser sensor 33. When the buffer portion moves to the discharging side, and the thorn pieces 101 in the buffer portion trigger the second laser sensor 33, the piston rod of the grouping cylinder 32 can accelerate the preset number of thorn pieces 101 in the buffer portion to the end of the buffer device 3 along the direction of the guide rail 31, and trigger the inductive switch of the feeding opening, and transmit a signal to the first robot 41, so as to facilitate the first robot 41 to grasp the thorn pieces 101 according to the signal. That is, the grouping cylinder 32 can push out the preset number of thorn pieces 101, so as to facilitate the first robot 41 to grasp, and the whole process does not need manual operation, and the efficiency is high.

[0056] The first robot 41 is equipped with multiple suction cups for adsorbing and fixing the barbed pieces 101. After a preset number of suction cups adsorb each barbed piece 101 from the end of the buffer device, each suction cup can move the barbed pieces 101 and rearrange them so that the barbed pieces 101 are arranged sequentially at intervals with the same spacing as the barbed pieces 101 of the barbed line. Then, the first robot 41 places each barbed piece 101 into the placement slot 711 of the welding fixture 71. In other words, the first robot 41 moves the required barbed pieces 101 to the welding fixture 71 simultaneously using multiple suction cups, which significantly improves production efficiency compared to placing each barbed piece 101 into the welding fixture 71 one by one. Specifically, the first robot 41 can use commercially available robots to achieve sequential arrangement of each plate according to a preset position, which will not be elaborated here.

[0057] The number of suction cups on the first robot 41 is not required. The number of suction cups can be exactly the number of barbed pieces 101 needed for one barbed wire, or the number of suction cups can be greater than the number of barbed pieces 101 needed for one barbed wire. Excess suction cups can be used as spares to improve applicability and flexibility. Alternatively, the number of suction cups can be less than the number of barbed pieces 101 needed for one barbed wire. If the number of barbed pieces 101 needed for one barbed wire is an integer multiple of the number of suction cups, it can be handled in two or more passes. The preset number can be exactly the number of barbed pieces 101 needed for one barbed wire, or the number of barbed pieces 101 needed for one barbed wire can be an integer multiple of the preset number.

[0058] When the first robot 41 moves the barbed pieces 101 to the welding fixture 71 a preset number of times (specifically, once, twice, or more), the first robot 41 has moved the number of barbed pieces 101 required for one barbed line to the welding fixture 71, and then the second robot 42 moves the round steel 102 to the welding fixture 71.

[0059] like Figure 5 As shown, the barbed wire production mechanism also includes a connecting bridge 6, a third robot 43, and a pusher 10. The connecting bridge 6 is located between the stamping equipment 1 and the vision inspection equipment 2. The connecting bridge 6 is equipped with a first laser sensor 61. The barbed pieces 101 can be moved from the unloading area of ​​the stamping equipment 1 to the connecting bridge 6 under the action of the pusher 10. The first laser sensor 61 is used to detect whether any barbed pieces 101 have reached a preset position. If so, the third robot 43 moves the barbed piece 101 located at the preset position to the detection position of the vision inspection equipment 2. The vision inspection equipment 2 inspects the barbed piece 101. If it is qualified, the third robot 43 can transfer the barbed piece 101 to the next station, namely the buffer equipment 3. If it is unqualified, the third robot 43 can remove the barbed piece 101 to ensure product quality.

[0060] The third robot 43 can rotate to move the barb 101 between the preset position of the connecting bridge 6, the vision inspection device 2 and the buffer device 3, so as to simplify the overall structure and layout.

[0061] In this embodiment, the specific structure of the visual inspection device 2 is not limited. For example, it can be equipped with a camera and intelligent AI to detect whether the various dimensional data of the formed barb sheet 101 meet the standards and perform intelligent screening to ensure the product qualification rate.

[0062] like Figure 3 As shown, the barbed wire production mechanism also includes a round steel feeding device 5, and a second robot 42 is located between the round steel feeding device 5 and the welding fixture 71. The round steel feeding device 5 is used to provide round steel 102, and the second robot 42 is used to move the round steel 102 provided by the round steel feeding device 5 to the welding fixture 71.

[0063] like Figure 6 As shown, the round steel feeding device 5 includes a first feeding platform 51, a second feeding platform 52, and a push cylinder 53 (such as a pneumatic cylinder or a hydraulic cylinder). The first feeding platform 51 has an inclined first platform surface for feeding round steel bars 102 to the second feeding platform 52. The height of the side of the first platform surface facing the second feeding platform 52 is lower than the height of the side away from the second feeding platform 52. The first feeding platform 51 can hold multiple round steel bars 102, and the round steel bars 102 placed on the first feeding platform 51 can roll along the first platform surface to the side facing the second feeding platform 52. The side of the second feeding platform 52 facing the first feeding platform 51 is also provided with a slot 521, which can only accommodate one round steel bar 102. The push cylinder 53 pushes the round steel bars 102 on the first feeding platform 51 upwards. After being pushed into the slot 521, a round steel bar 102 is stored in the slot 521. Then, the push cylinder 53 can further push the round steel bar 102 in the slot 521 to the second loading platform 52. The second loading platform 52 has an inclined second platform surface. The height of the side of the second platform away from the first loading platform 51 is lower than the height of the side facing the first loading platform 51. The bottom of the second platform surface is also equipped with rollers 522. The round steel bar 102 can move along the second platform surface to the rollers 522. When the round steel bar 102 is driven to the designated position by the rollers 522, the second robot 42 will grab the round steel bar 102 at the designated position and move it to the welding fixture 71, so that the round steel bar 102 fits with the concave wall surface of the arched structure 1012 of each barb 101. Finally, the welding robot 44 performs the welding operation on the round steel bar 102 and the barb 101.

[0064] A first contact sensor 54 may also be set at the designated position. The first contact sensor 54 is used to detect whether the round steel 102 has moved to the designated position. When the round steel 102 moves to the designated position under the action of the roller 83, it can trigger the first contact sensor 54. The first contact sensor 54 can limit the round steel 102 and transmit the signal to the second robot 42. After the second robot 42 receives the signal, it can grab and move the round steel 102 located at the designated position. At the same time, the first contact sensor 54 responds that the designated position is empty, and the push cylinder 53 will push the round steel 102 into the second loading platform 52 again to realize the automatic cyclic loading of the round steel 102.

[0065] The second robot 42 moves the round steel bar 102 from the designated position to the welding fixture 71 and sets the round steel bar 102 down. Simultaneously, it outputs a signal to enable the round steel bar clamping member 712 on the welding fixture 71 to clamp the round steel bar 102. The round steel bar clamping member 712 also includes a conductive fixture, which, while achieving clamping and fixing, also provides electrical conductivity to facilitate welding operations. The welding fixture 71 also has an opening at a position corresponding to the welding hole 1013 to facilitate welding operations.

[0066] like Figure 3 As shown, the barbed wire production mechanism includes a welding station 7, which has a loading position 72 and a welding position 73. The welding fixture 71 can reciprocate between the loading position 72 and the welding position 73. The first robot 41 can move the barbed piece 101 to the welding fixture 71 located at the loading position 72. The second robot 42 can move the round steel 102 to the welding fixture 71 located at the loading position 72. Then the welding fixture 71 moves to the welding position 73. The welding robot 44 with a welding gun will weld the connection between the barbed piece 101 and the round steel 102 at the corresponding welding hole 1013 position of the welding fixture 71 according to the set program.

[0067] Specifically, welding station 7 may also be equipped with a drive mechanism 74 for driving welding fixture 71 to switch between loading station 72 and welding station 73. The drive mechanism 74 may be a cylinder, hydraulic cylinder, motor screw assembly, etc. Furthermore, during the welding process, welding robot 44 may automatically move to the location of the next welding hole 1013, or the position of welding robot 44 may remain unchanged. After completing the welding of one barbed piece 101 to round steel 102, the drive mechanism 74 drives welding fixture 71 to move, so that the next barbed piece 101 to be welded can move to welding robot 44.

[0068] Furthermore, to facilitate welding operations, after the welding fixture 71 moves to the welding position 73, it can be flipped so that the barb 101 is above the round steel 102, so that the welding robot 44 can perform welding operations from the welding hole 1013. This embodiment does not limit how the welding fixture 71 is flipped. It can be achieved by the drive mechanism 74 or by a separately set flipping mechanism.

[0069] The welding position 73 may also be equipped with multiple photoelectric switches 75 to control the rotation position of the welding fixture 71, so that the welding robot 44 can select different welding angles according to different welding conditions.

[0070] like Figure 3 As shown, the barbed wire production mechanism also includes an inspection station 8 and a packing station 9 located downstream of the welding station 7. The inspection station 8 is equipped with an inspection device 82, which is used to inspect the welded barbed wire. The packing station 9 is used to pack the barbed wire that has passed the inspection at the inspection station 8.

[0071] After the barbed wire welding is completed, the welding fixture 71 is flipped so that the placement groove 711 faces upwards, and the clamping action of each round steel clamping part 712 is released. The downstream inspection robot 45, equipped with a gripper manipulator, receives the signal, picks up the barbed wire from the welding fixture 71, and transfers it to the downstream inspection station 8. Figure 8 As shown, the inspection station 8 is driven by the conveyor belt 84 to run the roller 83. The starting and ending positions of the inspection station 8 are respectively equipped with second contact sensors 81. When the barbed wire is placed on the inspection station 8, the second contact sensor 81 at the starting position is triggered, and the conveyor belt 84 starts to run, so that the barbed wire runs on the inspection station 8. A photoelectric sensing device is set in the running path to detect the welding qualification rate of the barbed wire. The photoelectric sensing device is used as the detection device 82 to perform product qualification inspection on the barbed piece 101, which makes the product defect detection more accurate and efficient.

[0072] The packing station 9 is located downstream of the inspection station and is equipped with a packing robot 46. When the qualified barbed wire is inspected at the inspection station 8 and moves to the end of the inspection station 8 and triggers the second contact sensor 81 at the termination position, the inspection station 8 will stop running. Then the packing robot 46 can grab the barbed wire and arrange it in the wooden box 91 in an orderly manner according to the program settings to complete the packing operation.

[0073] That is, in the barbed wire production mechanism provided by the embodiment, the stamping of the barbed sheet 101, the visual inspection of the barbed sheet 101, the buffering of the barbed sheet 101, the welding of the barbed sheet 101 and the round steel 102, and the detection and boxing of the product are all automatically implemented without manual operation, which completely changes the complicated mode of close cooperation between multiple production machines and manual operation in the traditional production process, thereby realizing highly unmanned production, greatly simplifying the production process, significantly improving the production efficiency, making the production process more efficient and smooth, reducing manpower and resources, lowering the production cost, avoiding the influence of product quality caused by manual operation errors or mistakes, and further ensuring the stability of product quality. This improvement has important practical significance for improving the competitiveness of production enterprises. Moreover, through precise control and intelligent adjustment, the waste of materials is effectively reduced, and the utilization rate of materials is improved.
