DETAILED DESCRIPTION

[0020] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0021] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] like Figure 1 As shown, an automatic positioning and punching device includes a stand (not shown). A feeding drive seat 1 is installed in the middle of the stand, and a table 2 is slidably connected to the feeding drive seat 1, and a plurality of linearly arranged adaptive support frames 6 are installed on the table 2. A lifting mechanism 4 is installed on each side of the feeding drive seat 1, and a rotary clamping mechanism 3 is installed at the output end of each lifting mechanism 4. The two sets of rotary clamping mechanisms 3 are arranged opposite to each other, and a driving component connected to the driving of one of the rotary clamping mechanisms 3 is provided on one side. A truss 7 is arranged above the two sets of rotary clamping mechanisms 3, and a laser punching mechanism 5 is slidably connected to the truss 7.

[0023] like Figure 2 As shown, the feeding drive seat 1 includes a base frame 8. The base frame 8 is fixedly mounted on the table surface of the table frame, and a lead screw 11 is mounted in the middle of the base frame 8 through a bearing seat, and a nut seat 4 fixed to the table plate 2 is arranged on the lead screw 11. A guide rod 10 is mounted on each side of the lead screw 11, and a slide seat fixed to the table plate 2 is arranged on the guide rod 10, and a servo motor 9 fixedly connected to the lead screw 11 is mounted at one end of the base frame 8.

[0024] The anilox roller is placed on the adaptive support frame 6. When the servo motor 9 is started, it drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the nut seat 4 matched with it to move linearly. The linear movement of the nut seat 4 drives the table 2 fixedly connected to it to move along the guide rod 10, thereby realizing the loading and unloading of the anilox roller. Fig.13As shown, a sensor 3 60 is installed at one end of the base frame toward one of the adaptive support frames 6. During the movement of the platform 2, the sensor 3 60 continuously detects the position of the adaptive support frame 6. If the adaptive support frame 6 is in place, the sensor 3 60 will send a signal to the control system, and the control system determines whether to continue moving the platform 2 or perform the next operation based on the signal.

[0025] like Figure 3-5 As shown, each adaptive support frame 6 includes a cover plate 12, a base body 13, a clamping arm 14 and a bottom block 15. The cover plate 12 is buckled on one side of the base body 13, and a movable groove 17 is provided on the side of the base body 13 facing the cover plate 12, and a movable cavity is formed between the movable groove 17 and the cover plate 12. The clamping arm 14 is arc-shaped, and there are two groups in total. The two groups of clamping arms 14 are distributed in a V shape and are rotatably installed inside the movable cavity. A half gear 20 is provided at the lower end of the clamping arm 14, and a rotating shaft 21 is provided on both sides of the half gear 20, and a rotating shaft hole 24 for accommodating the rotating shaft 21 is provided in the movable cavity. The two sides of the movable groove 17 are arc surfaces adapted to the outer contour of the clamping arm 14, and the groove depth of the movable groove 17 (the width of the active cavity) is consistent with the thickness of the clamping arm 14.

[0026] A support block 18 is provided in the middle of the two groups of clamp arms 14, a sliding column 19 passing through the support block 18 is provided at the bottom of the bottom block 15, and a groove 22 adapted to the bottom block 15 is provided at the top of the support block 18. The sliding column 19 is located between the two groups of half gears 20, and a plurality of groups of tooth grooves 25 meshing with the half gears 20 on both sides are provided on the sliding column 19. A clamp block 16 is hingedly connected to one side of the clamp arm 14 facing the bottom block 15, and a spring 23 is provided on the sliding column 19, and the spring 23 abuts between the bottom block 15 and the support block 18.

[0027] When the adaptive support frame 6 is placed in the anilox roller, the weight of the anilox roller causes the bottom block 15 to be pressed downward, causing the sliding column 19 to move downward. Since the half gear 20 at the lower end of the clamping arm 14 is meshed with the tooth groove 25 on the sliding column 19, the clamping arm 14 begins to rotate around the rotating shaft 21, and the distance between the two groups of clamping arms 14 gradually decreases until the clamping block 16 clamps the anilox roller.

[0028] like Fig.13 As shown, on one of the adaptive support frames 6, a sensor four 61 is provided on one side of the seat body 13 for real-time monitoring whether the anilox roller is placed in or removed from the adaptive support frame 6. The control system determines whether to proceed to the next operation based on the signal of the sensor four 61.

[0029] like Figure 6-7As shown, the two sets of rotary clamping mechanisms 3 both include a rotary drive seat and a chuck 28, and the chuck 28 is a pneumatic chuck to achieve automatic clamping. The rotary drive seat includes a mounting seat 33 and a base 26 mounted on the stand, and a bearing stand 29 is fixed on the mounting seat 33, and the chuck 28 is rotatably mounted on one side of the bearing stand 29. Side vertical plates 27 are provided on both sides of the base 26, and a lead screw 2 35 is installed between the two sets of side vertical plates 27, and a servo motor 3 32 connected to the lead screw 2 35 is fixed on one side of one side vertical plate 27, and a nut seat 1 34 fixed to the mounting seat 33 is provided on the lead screw 2 35. A guide rail 1 36 is provided on each side of the lead screw 2 35, and a slider 1 37 fixed to the mounting seat 33 is provided on the guide rail 1 36.

[0030] The two sets of rotary clamping mechanisms 3 execute commands synchronously during operation, but the rotation directions of the two sets of servo motors 3 32 are opposite. The servo motor 3 32 drives the lead screw 2 35 to rotate, and since the nut seat 1 34 is fixed on the mounting seat 33, the chuck 28 will slide along the guide rail 1 36, so that the two sets of chucks 28 are synchronously close to or away from the anilox roller.

[0031] like Fig.12 As shown, a sensor 58 facing the position of the anilox roller is installed on one side of the bearing stand 29. In the initial state, the claws on the chuck 28 are in the maximum open state, ready to clamp the anilox roller. When the sensor 3 60 detects that the adaptive support frame 6 is in place, it indicates that the anilox roller is in place. The control system sends a command to the servo motor 3 32 to drive it to start rotating. Driven by the servo motor 3 32, the chuck 28 approaches the anilox roller until the in-place signal of the sensor 58 is triggered, indicating that the chuck 28 has moved to the correct position, and then the claws of the chuck 28 begin to close and clamp the anilox roller.

[0032] One side of the rotary clamping mechanism 3 is provided with a driving assembly connected to the driving mechanism, and the driving assembly includes a servo motor 2 31. A support seat 30 is installed on the mounting seat 33 of the rotary clamping mechanism 3, and the servo motor 2 31 is fixed on one side of the support seat 30. The output shaft of the servo motor 2 31 is fixedly connected to the corresponding chuck 28 through a connecting piece to realize the transmission of power. Under the action of the control system, the servo motor 2 31 will rotate at a predetermined speed and direction. The rotational motion is transmitted to the chuck 28 through the connecting piece, so that the chuck 28 also rotates at the same speed and direction. The rotation of the chuck 28 will drive the anilox roller clamped thereon to rotate together, thereby performing the processing operation.

[0033] like Figure 8-10As shown, the laser drilling mechanism 5 includes a mounting plate 40 and a laser head 45, and the laser head 45 is fixed to one side of the mounting plate 40 through a laser driving seat. The laser driving seat includes a fixing plate 44 and two sets of guide rails 3 50 fixed to one side of the mounting plate 40, and each guide rail 3 50 is provided with a slider 2 47 mounted to the fixing plate 44. A lead screw 3 48 is installed between the two sets of guide rails 3 50, and a nut seat 2 49 mounted to the fixing plate 44 is provided on the lead screw 3 48. A servo motor 5 46 fixedly connected to the lead screw 3 48 is fixed to one side of the mounting plate 40. The servo motor 5 46 drives the lead screw 3 48 to rotate, so that the laser head 45 moves in the vertical direction.

[0034] A rack 41 is fixed to the top of the truss 7, a servo motor 439 is installed on the top of the mounting plate 40, and a gear 51 meshing with the rack 41 is fixed to the output end of the servo motor 439. Multiple sets of guide rails 238 are provided on the truss 7, and a slider 3 52 fixed to the mounting plate 40 is provided on the guide rails 238. When the servo motor 439 receives the command from the control system and starts to rotate, the gear 51 at its output end will mesh with the rack 41, thereby driving the laser head to move in the horizontal direction.

[0035] Locking pieces 43 are provided on both sides of the fixing plate 44, and tension springs 42 are hooked on the locking pieces 43, and one end of the tension spring 42 is hooked on the upper end of one side of the mounting plate 40. When the servo motor 5 46 drives the fixing plate 44 to move downward, the tension spring 42 will give the fixing plate 44 an upward force, which helps to reduce the impact and vibration caused by sudden stopping or starting, and protect the laser head 45 and other precision parts from damage.

[0036] like Fig.11 As shown, the lifting mechanism 4 includes a support plate 57 and a stand 53 mounted on the platform, and the rotary clamping mechanism 3 is fixed to the support plate 57. A lead screw 4 54 is installed on one side of the stand 53, and a servo motor 6 55 connected to the lead screw 4 54 is fixed on the top of the stand 53. A nut seat 3 fixed to the support plate 57 is provided on the lead screw 4 54, and a guide rail 4 56 is installed on each side of the lead screw 4 54, and a slider 4 fixed to the support plate 57 is provided on the guide rail 4 56.

[0037] The lifting mechanism 4 can automatically adjust the height according to the diameter of the inserted anilox roller, and is suitable for workpieces with different diameters. Fig.12As shown, a sensor 2 59 facing the base 26 is provided on one side of the stand 53 to realize real-time detection of the height of the base 26 (the height of the chuck 28 is reflected by detecting the height of the base 26). When the diameters of the anilox rollers placed in front and behind the adaptive support frame 6 are different, the distance detected by the sensor 4 61 will also change. The control system calculates the distance difference and then controls the height of the servo motor 6 55 to raise or lower. After the anilox roller is clamped, the lifting mechanism 4 drives the rotary clamping mechanism 3 to rise until the laser processing height of the sensor 2 59 is triggered.

[0038] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention.
