Description
Technical Field
[0001] This utility model belongs to the field of packaging and printing technology, and relates to an automatic alignment device for packaging and printed materials. Background Technology
[0002] Packaging printing refers to printed products using packaging materials or containers as carriers, and it is an important link in the circulation, protection, and display of goods. It uses printing technology to attach text, patterns, logos, and other information to the surface of packaging, combining functionality and promotional value. It is widely used in industries such as food, daily chemicals, pharmaceuticals, and electronics. Through stamping, cutting, and printing processes, cardboard is processed and then transformed into various gift boxes, etc.
[0003] When using the above technology, the following technical problems were found in the existing technology: When stamping and cutting cardboard, the cardboard needs to be aligned with the mold. However, in some existing alignment processes, manual alignment is required. Manual alignment depends on the operator's experience and skill, and it is difficult to ensure the consistency of positioning each time. For example, slight hand tremors or visual deviations of the operator may cause the relative position of the cardboard and the mold to shift, resulting in inaccurate cutting size. At the same time, manual alignment requires repeated adjustment of the cardboard position, which is cumbersome and inefficient. Therefore, there is an urgent need for a multi-functional integrated, compact decompression device with multimodal feedback. Utility Model Content
[0004] The technical problem this utility model aims to solve is that when stamping and cutting cardboard, the cardboard needs to be aligned with the mold. However, some existing alignment methods require manual alignment, which relies on the operator's experience and skill, making it difficult to guarantee the consistency of positioning each time. For example, slight hand tremors or visual deviations may cause the relative position of the cardboard and the mold to shift, resulting in inaccurate cutting dimensions. At the same time, manual alignment requires repeated adjustments to the cardboard position, which is cumbersome and inefficient.
[0005] The present invention discloses an automatic alignment device for printed packaging, comprising a bottom support frame, a sliding frame mounted at the top center of the bottom support frame, a first horizontal drive module and a second horizontal drive module slidably connected to the sliding frame, an alignment component mounted on the first horizontal drive module, a stamping equipment body connected to the bottom of the second horizontal drive module, a placement component mounted on the top of the sliding frame, and a conveyor belt mounted on the bottom support frame.
[0006] The bottom of the second horizontal drive module is equipped with the main body of the stamping equipment. The alignment component includes a connecting plate. The top of the connecting plate is connected to the first horizontal drive module. Cylinder telescopic rods are installed at the four corners of the bottom of the connecting plate. The bottom of the four cylinder telescopic rods is equipped with the same mounting plate.
[0007] The alignment component also includes a mounting box, with the top center of the mounting box bolted to the mounting box. Two mounting brackets are symmetrically mounted on the bottom of the mounting box, and the same high-frame vision sensor is mounted at the center of the connection between the two mounting brackets. A drive screw is rotatably connected to the center of the inner side of the mounting bracket, and a threaded drive block is threaded onto the drive screw. An adjustment plate is mounted at the bottom of the threaded drive block, and four electric telescopic rods are mounted in an array on the adjustment plate. Vacuum suction cups are mounted at the bottom of the electric telescopic rods. Sliding blocks are provided at both ends of the adjustment plate, and sliding rods are slidably connected to the sliding blocks. The two ends of the sliding rods are mounted on the inner side of the mounting bracket. A drive component is provided at one end of the mounting bracket, and a buffer component is provided at the inner end of the mounting bracket.
[0008] The drive unit includes a fixed housing, which is mounted on one end of a mounting frame. A servo motor is installed inside the fixed housing. A worm gear is connected to the output shaft of the servo motor. The worm gear is rotatably connected to the mounting housing. A worm wheel is meshed with the bottom of the worm gear. The worm wheel is mounted on the end of the drive screw that passes through the mounting frame.
[0009] The buffer component includes a support rod with both ends mounted on the inner side of the mounting frame. Multiple buffer rods are slidably connected in an array on the support rod. A buffer pad is installed at the bottom of each buffer rod, and a buffer spring is sleeved on each buffer rod. The two ends of the buffer spring are respectively connected to the bottom of the support rod and the top of the buffer pad.
[0010] The placement component includes a workbench, the bottom of which is mounted on a bottom support frame. The workbench is provided with multiple negative pressure adsorption holes, and a template mounting groove is provided at the center of the top of the workbench.
[0011] The placement assembly also includes a connecting pipe connected to the workbench. A vacuum pump is connected to the end of the connecting pipe away from the workbench. A fixing plate is connected to the bottom of the vacuum pump, and the fixing plate is mounted on the bottom support frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by scanning the feature points of the cardboard edge with a high-frame vision sensor and comparing them with the stamping points of the stamping equipment, the drive component drives the drive screw to rotate, causing the threaded drive block to move the adjustment plate and the adsorbed cardboard along the Y-axis. Combined with the first horizontal drive module driving the alignment component to move along the X-axis, the cardboard is automatically aligned in the XY-axis direction. Compared with the traditional manual alignment that relies on the operator's experience and skill, this design avoids the relative positional deviation between the cardboard and the mold caused by the operator's slight hand tremors or visual deviations, ensuring the consistency of each positioning and improving the accuracy of the stamping and cutting dimensions.
[0013] For excessively long cardboard, the adjusting plates on the two drive screws can be used to fix and adjust the position at both ends. This multi-dimensional and multi-point adjustment method can better adapt to cardboard of different sizes and shapes, further improving the accuracy of alignment. Attached Figure Description

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0028] Example 1
[0029] like Figures 1-8 As shown, an automatic alignment device for printed packaging includes a bottom support frame 1, a sliding frame 2 installed at the top center of the bottom support frame 1, a first horizontal drive module 3 and a second horizontal drive module 4 slidably connected to the sliding frame 2, an alignment component installed on the first horizontal drive module 3, a stamping equipment body 5 connected to the bottom of the second horizontal drive module 4, a placement component installed on the top of the sliding frame 2, and a conveyor belt 31 installed on the bottom support frame 1.
[0030] After the first horizontal drive module 3 drives the alignment component to position the cardboard, the second horizontal drive module 4 drives the main body 5 of the stamping equipment to move above the cardboard for stamping and cutting. Through the operation of the first horizontal drive module 3 in conjunction with the alignment component, the device can automate the alignment process quickly and efficiently, eliminating the need for operators to repeatedly adjust the position of the cardboard, greatly shortening the alignment time and improving the overall work efficiency.
[0031] The second horizontal drive module 4 has a stamping equipment body 5 installed at its bottom. The alignment component includes a connecting plate 6, the top of which is connected to the first horizontal drive module 3. Cylinder telescopic rods 7 are installed at the four corners of the bottom of the connecting plate 6. The bottom of the four cylinder telescopic rods 7 is fitted with the same mounting plate 8. The alignment component also includes a mounting box 9, the top center of which is bolted to the mounting box 9. Two mounting brackets 10 are symmetrically installed at the bottom of the mounting box 9. A high-frame vision sensor 32 is installed at the center of the connection between the two mounting brackets 10. The inner side of the mounting bracket 10... A drive screw 11 is rotatably connected in the middle. A threaded drive block 12 is threadedly connected to the drive screw 11. An adjustment plate 13 is installed at the bottom of the threaded drive block 12. Four electric telescopic rods 14 are installed in an array on the adjustment plate 13. A vacuum suction cup 15 is installed at the bottom of the electric telescopic rods 14. Sliding blocks 16 are provided at both ends of the adjustment plate 13. Sliding rods 17 are slidably connected to the sliding blocks 16. Both ends of the sliding rods 17 are installed inside the mounting frame 10. A drive component is provided at one end of the mounting frame 10. A buffer component is provided at the inner end of the mounting frame 10.
[0032] During operation, the conveyor belt 31 transports the external cardboard to below the alignment component. Then, the four cylinder extension rods 7 on the alignment component drive the internal vacuum suction cup 15 downwards, bringing it into contact with the top surface of the cardboard. Negative pressure then causes the vacuum suction cup 15 to hold the cardboard in place. After suction, the cylinder extension rods 7 reset the cardboard. The first horizontal drive module 3 then drives the vacuum suction cup 15 on the alignment component to move horizontally along the X-axis while holding the cardboard. The first horizontal drive module 3 moves the cardboard on the alignment component above the placement component. The vacuum suction cup 15 on the placement component places the cardboard on the placement component. A high-frame-rate vision sensor 32 scans the cardboard, extracting edge feature points and comparing them with the stamping points of the stamping equipment. If there is a misalignment, the high-frame-rate vision sensor 32 sends the parameters to the industrial control computer. The industrial control computer then controls the suction cup's movement, causing the electric extension rods on the adjusting plate 13 to extend... The retractor 14 drives the vacuum suction cup 15 downward, thereby adsorbing the cardboard placed on the middle component. The driving component drives the drive screw 11 to rotate, and the drive screw 11 drives the threaded drive block 12 connected to it to move horizontally along the Y-axis. The threaded drive block 12 drives the adjusting plate 13 connected to it to move. The sliding blocks 16 at both ends of the adjusting plate 13 slide synchronously on the sliding rod 17, so that the electric telescopic rod 14 connected to the adjusting plate 13 and the adsorbed cardboard move horizontally along the Y-axis. The first horizontal drive module 3 drives the alignment component to move horizontally along the X-axis. By moving in the X and Y directions, the position of the cardboard is adjusted so that the cardboard can be aligned and placed on the stamping point of the stamping equipment, realizing automatic alignment without manual positioning. If the cardboard is too long, the adjusting plates 13 on the two drive screws 11 can be used to fix the two ends for adjustment.
[0033] By scanning the feature points of the cardboard edge with a high-frame vision sensor 32 and comparing them with the stamping points of the stamping equipment, the drive screw 11 is rotated by the drive component, which causes the threaded drive block 12 to move the adjustment plate 13 and the adsorbed cardboard along the Y-axis. Combined with the first horizontal drive module 3, the alignment component moves along the X-axis, realizing the automatic alignment of the cardboard in the XY-axis direction. Compared with the traditional manual alignment that relies on the operator's experience and skill, this design avoids the relative positional deviation between the cardboard and the mold caused by the operator's slight hand tremors or visual deviations, ensuring the consistency of each positioning and improving the accuracy of the stamping and cutting dimensions.
[0034] Example 2
[0035] like Figures 1-6 As shown, the driving component includes a fixed housing 21, which is mounted on one end of the mounting frame 10. A servo motor 20 is installed inside the fixed housing 21, and a worm gear 19 is connected to the output shaft of the servo motor 20. The worm gear 19 is rotatably connected to the mounting housing 9, and a worm wheel 18 is meshed with the bottom of the worm gear 19. The worm wheel 18 is mounted on one end of the drive screw 11 that passes through the mounting frame 10. During operation, the servo motor 20 inside the mounting housing 9 drives the worm gear 19 to rotate inside the mounting housing 9. In turn, the worm gear 19 drives the worm wheel 18, which is meshed with it, to rotate. The worm wheel 18 drives the drive screw 11, which is connected to it, to rotate. In turn, the drive screw 11 drives the cardboard to adjust its position through the threaded drive block 12. The meshing between the worm gear 19 and the worm wheel 18 has a self-locking characteristic. When the drive screw 11 does not need to rotate, it can prevent it from rotating due to external forces or its own factors, ensuring that the position of the cardboard remains stable and improving the reliability of the entire system.
[0036] The buffer component includes a support rod 22, with both ends of the support rod 22 mounted on the inner side of the mounting frame 10. Multiple buffer rods 23 are slidably connected in an array on the support rod 22. A buffer pad 25 is installed at the bottom of the buffer rod 23, and a buffer spring 24 is sleeved on the buffer rod 23. The two ends of the buffer spring 24 are connected to the bottom of the support rod 22 and the top of the buffer pad 25, respectively. During operation, when the alignment component places the cardboard that has been adsorbed by the cylinder telescopic rod 7, the buffer pad 25 contacts the placement component, causing the buffer rod 23 to slide on the adjusting rod. The buffer spring 24 uses its elastic characteristics to provide buffering.
[0037] Example 3
[0038] like Figure 1 , Figure 7 and Figure 8As shown, the placement component includes a workbench 26, the bottom of which is mounted on a bottom support frame 1. The workbench 26 is provided with multiple negative pressure adsorption holes 27. A template mounting groove 261 is opened in the middle of the top of the workbench 26. The placement component also includes a connecting pipe 28, which is connected to the workbench 26. The end of the connecting pipe 28 away from the workbench 26 is connected to a vacuum pump 29. The bottom of the vacuum pump 29 is connected to a fixing plate 30, which is mounted on the bottom support frame 1.
[0039] During operation, the template mounting slot 261 in the middle of the workbench 26 can be used to install the stamping die. After the stamping die is installed, the alignment component places the cardboard on the workbench 26. By adjusting the alignment component, the cardboard is positioned. Then, the negative pressure pump uses the connecting pipe 28 to evacuate the negative pressure adsorption hole 27, so that the edge of the cardboard is adsorbed by negative pressure, making the cardboard more stable during stamping.
