Description

Technical Field

[0001] The present invention relates to the field of easy-open lid processing, and in particular to a punching machine for precisely riveting and cutting a pull ring and a lid. Background Art

[0002] Riveting the tab of an easy-open lid involves connecting the tab to the edge of the lid using rivets. Specifically, the tab is riveted to the edge of the lid. This design allows the lid to be opened safely along the pre-scored score line while maintaining a secure hold on the tab.

[0003] For example, the invention patent with application number CN201810809567.1 discloses a box cover pull ring riveting machine, including a main frame, an easy-open cover feeding mechanism, an easy-open cover shaping and positioning mechanism, a pull ring feeding mechanism, a pull ring picking device, a riveting device, a finished product unloading device, a finished product conveying device, and a finished product stacking device.

[0004] In the prior art, in the process of punching and riveting the pull ring of the easy-open lid, it is necessary to first place the easy-open lid and the pull ring on a conveying device, and then transport the easy-open lid and the pull ring to the riveting device through the conveying device. During the transportation of the easy-open lid, the easy-open lid is easily shaken by mechanical vibration, causing the easy-open lid to shift on the conveying device, thereby causing the riveting position to shift, resulting in reduced processing accuracy.

[0005] To this end, the present invention proposes a punching machine for precise riveting and cutting of a pull ring and a cover to solve the above problems. Summary of the Invention

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a punching machine for precise riveting and cutting of pull rings and lids, comprising:

[0007] A machine tool, wherein a conveying plate is slidably connected in the machine tool, an array of grooves is provided on the top surface of the conveying plate, a limiting disk is rotatably connected in the groove, and the limiting disk is used to limit the easy-open cover;

[0008] A positioning plate, wherein an L-shaped bracket is symmetrically fixedly connected to the outer side of the positioning plate, and the L-shaped bracket is slidably connected to the inner wall of the machine tool. The positioning plate is located above the conveying plate, and two arc-shaped slide grooves are symmetrically provided on the top of the positioning plate. An arc-shaped slider is slidably connected in the arc-shaped slide groove, and the bottom end of the slider is fixedly connected to an arc-shaped push block adapted to the front end surface of the pull ring;

[0009] a first pushing assembly, the first pushing assembly being used to push the positioning plate to move the positioning plate downward, so that the arc-shaped pushing block moves to the top of the easy-open lid;

[0010] The second pushing component is used to push the arc-shaped pushing block so that the arc-shaped pushing block moves along the arc-shaped sliding groove.

[0011] Specifically, first, the assembled pop-top lids are placed one by one into the limit discs on the conveying plate by means of a robotic arm or manually. Then, the conveying plate is moved by an external transmission device so that the pop-top lids are conveyed one by one to the mounting seat for stamping and riveting.

[0012] During the process of the conveying plate conveying the pop-top lids, the pop-top lid first moves to directly below the positioning disc. Subsequently, through the first pushing component, the positioning disc moves downward, causing the arc-shaped pushing block to move downward to the top of the pop-top lid.

[0013] Then, through the second pushing component, the arc-shaped slider drives the arc-shaped pushing block to move along the arc-shaped sliding groove, causing the two arc-shaped pushing blocks to approach each other. If the rivets on the pop-top lid are not in the accurate position, during the process of the two arc-shaped pushing blocks approaching each other, the two arc-shaped pushing blocks will push the front end face of the pull ring, and by pushing the pull ring, the pop-top lid rotates to push the riveting to the specified position, which is beneficial to improving the processing accuracy.

[0014] After the adjustment is completed, the conveying plate continues to convey. During the conveying process of the conveying plate, the position of the rivet is detected by a laser sensor.

[0061] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0062] As Figures 1 to 12A kind of precision riveting and cutting integrated punching machine for pull rings and covers shown in the figure includes:

[0063] A machine tool 1, a conveying plate 2 is slidably connected inside the machine tool 1. A plurality of grooves are arranged in an array on the top surface of the conveying plate 2. A limiting disk 3 is rotatably connected inside the groove. The limiting disk 3 is used to limit the easy-open lid 4; A positioning disk 5, symmetrically fixed with L-shaped brackets 6 on the outside of the positioning disk 5. The L-shaped brackets 6 are slidably connected to the inner wall of the machine tool 1. The positioning disk 5 is located above the conveying plate 2. Two arc-shaped chutes 7 are symmetrically arranged at the top end of the positioning disk 5. An arc-shaped slider 8 is slidably connected inside the arc-shaped chute 7. The bottom end of the slider is fixedly connected with an arc-shaped pushing block 9 adapted to the front surface of the pull ring 401; A first pushing component, the first pushing component is used to push the positioning disk 5 to move the positioning disk 5 downward so that the arc-shaped pushing block 9 moves to the top of the easy-open lid 4; A second pushing component, the second pushing component is used to push the arc-shaped pushing block 9 to move the arc-shaped pushing block 9 along the arc-shaped chute 7.

[0064] A mounting seat 35, the bottom end of the mounting seat 35 is fixedly connected to the top end of the machine tool 1. A fixed seat 36 is fixedly connected inside the mounting seat 35. A hydraulic cylinder 37 is arranged inside the fixed seat 36. The bottom end of the hydraulic cylinder 37 is fixedly connected with a pressing block 38.

[0065] A laser sensor 39, the laser sensor 39 is arranged at the bottom end of the fixed seat 36 and is used to obtain the position of the rivet 402.

[0066] Specifically, in the prior art, during the process of stamping and riveting the pull ring 401 of the easy-open lid 4, it is necessary to first place the easy-open lid 4 and the pull ring 401 on the conveying device, and convey the easy-open lid 4 and the pull ring 401 to the riveting device through the conveying device. During the process of conveying the easy-open lid 4, affected by mechanical vibration, the easy-open lid 4 is likely to shake, causing the easy-open lid 4 to shift on the conveying device, resulting in the shift of the riveting position and the reduction of processing accuracy. This technical solution can solve the above problems. The specific operation is as follows. First, place the assembled easy-open lids 4 one by one into the limiting disks 3 on the conveying plate 2 by means of a robotic arm or manually. Then, move the conveying plate 2 through an external transmission device to convey the easy-open lids 4 one by one to the mounting seat 35 for stamping and riveting.

[0067] During the process of the conveying plate 2 conveying the easy-open lid 4, the easy-open lid 4 first moves to directly below the positioning disk 5, and then through the first pushing component, the positioning disk 5 moves downward, so that the arc-shaped pushing block 9 moves downward to the top of the easy-open lid 4.

[0068] Next, through the second pushing component, the arc-shaped slider 8 drives the arc-shaped pushing block 9 to move along the arc-shaped chute 7, causing the two arc-shaped pushing blocks 9 to approach each other. If the rivet 402 on the easy-open lid 4 is not in the accurate position, during the process of the two arc-shaped pushing blocks 9 approaching each other, the two arc-shaped pushing blocks 9 will push the front face of the pull ring 401, and by pushing the pull ring 401, the easy-open lid 4 is rotated to push the rivet to the designated position, which is beneficial to improving the processing accuracy.

[0069] After the adjustment is completed, the conveying plate 2 continues to convey. During the conveying process of the conveying plate 2, the position of the rivet 402 is detected by the laser sensor 39. When the rivet 402 moves to directly below the pressing block 38, the conveying plate 2 stops moving. On the one hand, it is beneficial to move the rivet 402 to the accurate position and improve the processing accuracy. On the other hand, it makes the previous easy-open lid 4 accurately move to directly below the positioning disk 5, which is beneficial to adjusting the rivet 402 to the designated position.

[0070] Finally, by starting the hydraulic cylinder 37, the telescopic rod of the hydraulic cylinder 37 moves downward, and the rivet 402 is punched through the pressing block 38, thus completing the riveting process of the pull ring 401 and the easy-open lid 4.

[0071] As an optional implementation manner of the first pushing component, the first pushing component includes:

[0072] A cylinder 12, the cylinder 12 is fixedly connected to the top end of the machine tool 1, the telescopic rod of the cylinder 12 penetrates through the bottom end of the machine tool 1 and is fixedly connected to a first spring 13, and the bottom end of the first spring 13 is fixedly connected to the top end of the positioning disk 5.

[0073] As an optional implementation manner of the second pushing component, the second pushing component includes:

[0074] Two driving frames 14, the two driving frames 14 are symmetrically rotatably connected to the inner top end of the machine tool 1. Straight grooves are provided at the top ends of the two driving frames 14, a driving block 15 is slidably connected in the straight grooves, a sleeve 16 is rotatably connected in the driving block 15, and the top end of the rotating shaft of the rotating frame 10 is slidably inserted into the sleeve 16.

[0075] A first gear 17, the first gear 17 is coaxially fixed to the driving frame 14.

[0076] A U-shaped rack frame 18, the U-shaped rack frame 18 is slidably connected to the inner top end of the machine tool 1, and the U-shaped rack frame 18 meshes with the first gear 17.

[0077] A driving plate 19, the driving plate 19 is fixedly connected to the top end of the U-shaped rack frame 18. A driving groove 20 is provided on the side wall of the driving plate 19, and the driving groove 20 has a driving vertical groove and a driving inclined groove.

[0078] The bottom end of the telescopic rod of the cylinder 12 is fixedly connected with a driving rod 21, and the end of the driving rod 21 is slidably connected in the driving groove 20;

[0079] Specifically, after the easy-open lid 4 moves to directly below the positioning disk 5, the cylinder 12 is started, so that the telescopic rod of the cylinder 12 moves downward. Through the connection of the first spring 13, the positioning disk 5 drives the L-shaped bracket 6 to move downward, so that the arc-shaped pushing block 9 approaches the top of the easy-open lid 4. At this time, the driving rod 21 moves along the driving vertical groove, and the U-shaped rack frame 18 does not move;

[0080] Subsequently, the bottom end of the L-shaped bracket 6 moves to the bottom end inside the machine tool 1, and the arc-shaped pushing block 9 moves to the top of the easy-open lid 4 and contacts it. Then, the telescopic rod of the cylinder 12 continues to move, compressing the first spring 13. During the compression of the first spring 13, the driving rod 21 moves along the driving inclined groove. Driven by the driving inclined groove, the driving plate 19 drives the U-shaped rack frame 18 to move, so that the first gear 17 rotates, the driving frame 14 rotates, and the arc-shaped slider 8 moves along the arc-shaped chute 7, so that the two arc-shaped pushing blocks 9 approach each other, and the easy-open lid 4 is rotated by pushing the pull ring 401, so as to push the riveting to the specified position, which is beneficial to improving the processing accuracy.

[0081] As a further embodiment of the present invention, it further includes:

[0082] A rotating frame 10, one end of the rotating frame 10 is rotatably connected to the side wall of the arc-shaped pushing block 9, and the other end extends close to the rear end face of the pull ring 401. A pushing wheel 11 is rotatably connected to the end of the rotating frame 10 away from the arc-shaped pushing block 9;

[0083] A flipping drive assembly for driving the rotating frame 10 to rotate, so that the two rotating frames 10 approach each other to push the pull ring 401 to a specified position;

[0084] Specifically, during the transportation process, the pull ring 401 is also prone to deflection due to the shaking generated during transportation. Therefore, by providing the rotating frame 10 and the pushing wheel 11, during the process of the two arc-shaped pushing blocks 9 approaching each other, the flipping drive assembly drives the rotating frame 10 to rotate, so that the two rotating frames 10 approach each other, so that the two pushing wheels 11 approach each other. During the approach of the two pushing wheels 11, the pull ring 401 will be pushed to be straightened, so that the position of the pull ring 401 is adjusted to an accurate position, thereby further improving the processing accuracy.

[0085] As an optional implementation manner of the flipping drive assembly, the flipping drive assembly includes:

[0086] An arc-shaped rack plate 22, which is fixedly connected to the top end of the positioning disk 5;

[0087] The second gear 23 is coaxially fixed to the rotating frame 10, and a torsion spring 24 is fixedly connected between the rotating frame 10 and the arc-shaped slider 8;

[0088] Specifically, during the process of the two arc-shaped sliders 8 moving along the arc-shaped chute 7, the second gear 23 will pass by the arc-shaped rack plate 22, and the arc-shaped rack plate 22 drives the second gear 23 to rotate, so that the rotating frame 10 rotates, making the two rotating frames 10 approach each other, and thus making the two pushing wheels 11 approach each other. During the process of the two pushing wheels 11 approaching, they will push the pull ring 401 to be straightened, so as to adjust the position of the pull ring 401 to an accurate position, thereby further improving the processing accuracy.

[0089] As a further embodiment of the present invention, it further includes:

[0090] Two arc-shaped damping plates 25 are symmetrically and slidably connected in the conveying plate 2. A pushing inclined groove 26 is provided at the end of the arc-shaped damping plate 25, and a second spring 27 is fixedly connected between the arc-shaped damping plate 25 and the conveying plate 2;

[0091] Two first push rods 28 are symmetrically and fixedly connected to the side wall of the L-shaped bracket 6;

[0092] Specifically, by setting the arc-shaped damping plate 25 and the first push rod 28, during the process of the L-shaped bracket 6 moving downward, the first push rod 28 moves downward into the pushing inclined groove 26. Driven by the pushing inclined groove 26, the arc-shaped damping plate 25 moves away from the axis of the limit disk 3, thereby releasing the limiting effect on the limit disk 3. At this time, the second spring 27 is compressed. Subsequently, the pull tab 4 is adjusted through the above operations, so that the limit disk 3 rotates synchronously during the adjustment of the pull tab 4. After the adjustment is completed, the L-shaped bracket 6 moves upward, and the first push rod 28 moves upward, so that the arc-shaped damping plate 25 resets, thereby re-limiting the limit disk 3, and then limiting the pull tab 4, which is beneficial to avoiding the problem that the pull tab 4 shakes during the subsequent transportation process, resulting in the deviation of the position of the rivet 402.

[0093] As a further embodiment of the present invention, it further includes:

[0094] A camera 29 is fixedly connected in the machine tool 1, and the camera 29 is used to obtain the position information of the pull ring 401;

[0095] A mounting frame 30 is fixedly connected to the side wall of the L-shaped bracket 6, and a second push rod 31 is fixedly connected to the side wall of the mounting frame 30;

[0096] A rotation driving mechanism is used to drive the limit disk 3 to rotate;

[0097] The rotation drive mechanism includes:

[0098] A drive motor 32, with a first electromagnet 33 fixedly connected to the top end of the drive motor 32;

[0099] A second electromagnet 34, with the second electromagnet 34 fixedly connected to the bottom end of the rotating shaft of the limit disk 3;

[0100] Specifically, before the pull tab can 4 moves to the positioning disk 5, the pull tab can 4 will first move to the position of the camera. When the L-shaped bracket 6 moves downward, it will drive the mounting addition and the second push rod 31 to move downward, so that the second push rod 31 enters the push chute 26. Driven by the push chute 26, the arc damping plate 25 moves away from the axis of the positioning disk 5, releasing the limiting effect on the limit disk 3. Then, the position information of the pull ring 401 is obtained by taking a picture with the camera. If the position of the pull ring 401 exceeds the adjusted position, the drive motor 32 is started, and the output shaft of the drive motor 32 rotates. Under the attraction of the first electromagnet 33 and the second electromagnet 34, the positioning disk 5 rotates, thereby driving the pull tab can 4 to rotate, so as to adjust the pull ring 401 to a position where it can be pushed and adjusted by the two arc-shaped push blocks 9;

[0101] After the adjustment is completed, the first electromagnet 33 is turned off, so that the first electromagnet 33 and the second electromagnet 34 are disconnected. At the same time, the L-shaped bracket 6 moves upward, so that the arc damping plate 25 resets, thereby re-limiting the limit disk 3, and then limiting the pull tab can 4, which is beneficial to avoiding the problem that the pull tab can 4 shakes during the next transportation process, causing the position of the rivet 402 to shift;

[0102] Finally, the conveyor plate 2 moves, moving the pull tab can 4 to the lower part of the limit disk 3, and then adjusting the position of the pull tab can 4 further according to the above operation, so that the rivet 402 and the pull ring 401 move to the accurate positions, improving the processing accuracy.

[0103] The working principle of the present invention:

[0104] First, the assembled pull tab cans 4 are placed one by one into the limit disk 3 on the conveyor plate 2 by means of a robotic arm or manually. Then, the conveyor plate 2 is moved through an external transmission device, so that the pull tab cans 4 are conveyed one by one to the mounting seat 35 for stamping and riveting;

[0105] During the process of the conveyor plate 2 conveying the pull tab cans 4, the pull tab cans 4 first move to directly below the positioning disk 5. Subsequently, through the first pushing assembly, the positioning disk 5 moves downward, so that the arc-shaped push block 9 moves downward to the top of the pull tab can 4;

[0106] Subsequently, through the second driving component, the arc-shaped slider 8 drives the arc-shaped pushing block 9 to move along the arc-shaped sliding groove 7, causing the two arc-shaped pushing blocks 9 to approach each other. If the rivet 402 on the easy-open lid 4 is not in the accurate position, during the process of the two arc-shaped pushing blocks 9 approaching each other, the two arc-shaped pushing blocks 9 will push the front face of the pull ring 401, and by pushing the pull ring 401, the easy-open lid 4 is rotated to push the rivet to the designated position, which is beneficial to improving the processing accuracy.

[0107] After the adjustment is completed, the conveying plate 2 continues to convey. During the conveying process of the conveying plate 2, the position of the rivet 402 is detected by the laser sensor 39. When the rivet 402 moves to directly below the pressing block 38, the conveying plate 2 stops moving. On the one hand, it is beneficial to move the rivet 402 to the accurate position and improve the processing accuracy. On the other hand, it enables the previous easy-open lid 4 to be accurately moved to directly below the positioning disk 5, which is beneficial to adjusting the rivet 402 to the designated position.

[0108] Finally, by starting the hydraulic cylinder 37, the telescopic rod of the hydraulic cylinder 37 moves downward, and the rivet 402 is punched by the pressing block 38, thereby completing the riveting process of the pull ring 401 and the easy-open lid 4.

[0109] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
