Description

Technical Field

[0001] This invention relates to the technical field of production lines for fully automated pad printing, inspection, and bagging of plastic parts, and in particular to a high-efficiency automatic bagging equipment and a fully automated production line. Background Technology

[0002] Traditional pad printing processes rely heavily on manual operation, resulting in low production efficiency, high labor intensity, and unstable printing quality due to human factors. With the development of industrial technology, the market often finds that automated pad printing equipment has insufficient integration, limited automation, and difficulty in meeting the flexibility requirements of multi-variety, small-batch production.

[0003] Therefore, it is necessary to study a fully automated pad printing production line that, through highly integrated automated control, enables unmanned operation of the entire process from loading to unloading of pad printing products, thereby improving production efficiency, reducing production costs, and ensuring printing accuracy and consistency, thus meeting the requirements of modern industrial production for high efficiency, high quality, and flexibility.

[0004] After printing, for some delicate products or products with high appearance requirements, bagging is necessary to prevent scratches during transportation. This involves placing the product in a PET plastic inner bag to prevent damage. Currently, most companies in the market still use manual bagging, which is inefficient. While some automatic bagging machines have emerged, their complex structures and overall bagging speed do not meet the production requirements of high-speed pad printing production lines.

[0005] For example, CN116552913A discloses a bag opening and bagging machine, including a frame, a conveyor line inside the frame, a shaping mechanism at the front end of the conveyor line, a bag picking mechanism, a bag opening mechanism, a bagging mechanism, and a bag opening sorting mechanism at the rear of the conveyor line, and a belt pressing mechanism at the end of the conveyor line. The shaping mechanism includes a material support frame, with a pusher plate and a positioning plate on both sides of the material support frame. The bag picking mechanism includes a tray device, with a suction cup installed at the front end of the tray device to pick up the packaging bag. The bag opening mechanism includes a bag opening arm, with jaws on the bag opening arm to open the packaging bag. The bagging mechanism includes a lifting device and a bagging device. The lifting device lifts the PCB board, and the bagging device performs bagging through a clamping bracket. The bag opening sorting mechanism includes a bag stretching arm, which stretches the packaging bag. The belt pressing mechanism includes a pressure strip, which presses down the opening of the packaging bag for conveying.

[0006] Therefore, it is necessary to study a high-efficiency automatic bagging device that can meet the requirements of rapid pad printing in a fully automated pad printing production line and improve the overall production efficiency of the line. Summary of the Invention

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0043] Please see Figures 1 to 9 In this embodiment of the invention, a high-efficiency automatic bagging device includes:

[0044] The combined conveyor belt 10 is composed of multiple material conveyor belts 11 arranged side by side. The ends of each material conveyor belt 11 are spaced a certain distance apart along its conveying direction, and each material conveyor belt 11 is provided with a barrier strip 12 at its end to keep the material at the end of each material conveyor belt 11.

[0045] The bag supply device 20 is equipped with a bag supply box 21 and multiple sets of bag supply suction cups 22. The bag supply suction cups 22 pick up multiple plastic inner bags from the bag supply box 21 and move them to the bag-supporting station.

[0046] The bag-supporting device 40 is equipped with multiple sets of support rod assemblies 41, which are installed at the bag-supporting station to open the plastic inner bag and keep the plastic inner bag in an open state.

[0047] The clamping device 60 is equipped with multiple clamping arms, which can simultaneously clamp multiple material parts placed on the material conveyor belt 11 and insert the material parts into the plastic inner bag opened by the corresponding support rod assembly 41 to complete the bagging operation of the material parts.

[0048] The unloading conveyor belt 13 is used to receive the materials after the clamping device 60 has completed bagging and to perform the unloading operation; and

[0049] The main beam frame 14 is equipped with a main slide rail 15 and a main drive component. The bag supply device 20 and the clamping device 60 are slidably connected to the main slide rail 15 and form a transmission connection with the main drive component.

[0050] Specifically, to improve the operating efficiency of the bagging equipment, it is preferable to set up three material conveyor belts 11, so that three pad-printed materials can be simultaneously transported into the bagging equipment. Understandably, a corresponding photoelectric sensor can be set at the beginning of the combined conveyor belt 10 to detect the material being conveyed in. When the material is conveyed to the end of the material conveyor belt 11 and blocked by the blocking bar 12, it is preferable to automatically control the conveyor belt to stop operating, waiting for the clamping device 60 to clamp the material.

[0051] Once all three material conveyor belts 11 have materials at their ends, the clamping drive assembly 17 operates, moving the clamping arms to the rear of the materials. Then, the clamping vertical movement cylinder 65 drives the clamping plate 66 downwards, causing the clamping arms to clamp the materials. Subsequently, the first cylinder 68 and the second cylinder 610 operate respectively, driving the first clamping arm 61 and the second clamping arm 62 to move, thus arranging the three clamping arms in a row along the direction of the bag-supporting device 40. This facilitates the simultaneous insertion of the three materials into the three opened plastic inner bags.

[0052] The bag supply box 21 contains stacked plastic inner bags. Driven by the bag supply drive assembly 16, the bag supply suction cup 22 can move to the top of the starting end of the empty box output conveyor belt 31. A bag supply box 21 containing plastic inner bags is fixed here. Then, the bag supply vertical movement module 24 drives the bag supply suction cup 22 to move downward, so that the bag supply suction cup 22 can pick up the plastic inner bags inside the bag supply box 21 and move to the front end of the bag supporting device 40, waiting for the bag supporting device 40 to be inserted into the plastic inner bags.

[0053] like Figure 7As shown, since the initial state of the plastic inner bag is flat, a bag support strip 44 is inserted to form an opening. Preferably, an opening suction nozzle 47 is also provided on the side of the feeding conveyor belt 13 near the bag support device 40. The bag supply suction cup 22 moves the absorbed plastic inner bag downward, so that its lower side is close to the feeding conveyor belt 13 and is attracted by the opening suction nozzle 47. Then, the bag supply suction cup 22 moves upward a certain distance, so that the plastic inner bag forms a certain opening.

[0054] Subsequently, driven by the insertion cylinder 45, the support rod assembly 41 moves along the insertion slide rail 46 towards the open plastic inner bag, thereby inserting the support strips 44 on the first vertical plate 42 and the second vertical plate 43 into the interior of the plastic inner bag. Then, the support rod motor 52 drives the support rod synchronous belt 53 to rotate at a certain angle, thereby separating the first vertical plate 42 and the second vertical plate 43 by a certain distance, thus opening the plastic inner bag and keeping it in an open state. Driven by the clamping drive assembly 17, the clamping device 60 moves towards the open plastic inner bag, inserting the material into the plastic inner bag. It then continues to move a certain distance towards the feeding conveyor belt 13 and places the material into the plastic inner bag onto the feeding conveyor belt 13 for feeding. Finally, each device, mechanism, or component returns to its original position, ready for the next bagging operation.

[0055] Secondly, the main drive unit includes a bag feeding drive assembly 16 and a material clamping drive assembly 17. The bag feeding drive assembly 16 is driven to the bag feeding device 20 and drives the bag feeding device 20 to move back and forth along the main slide rail 15, thereby completing the corresponding movement operation. The material clamping drive assembly 17 is driven to the material clamping device 60 and drives the material clamping device 60 to move back and forth along the main slide rail 15, thereby completing the corresponding movement operation. Each set of support rod assemblies 41 is set at the material position at the end of each material conveyor belt 11 and performs an opening operation on the plastic inner bag, while stably keeping the plastic inner bag in an open state that can be bagged.

[0056] Secondly, it can significantly improve production efficiency. Automated operation reduces manual intervention and greatly increases production speed. It can also reduce production costs, decrease manpower requirements, reduce labor intensity, and improve material utilization. Furthermore, it can ensure printing quality. High-precision positioning and stable pad printing processes ensure consistent and stable printing quality. Simultaneously, it enhances the level of intelligence by using an intelligent control system to achieve real-time monitoring and analysis of production data, optimizing the production process. After printing, the system automatically moves the products to the unloading area and uses a machine vision system to perform quality inspection, identifying and rejecting defective products to ensure the quality of the final product. Integrating PLC, touch screen, and industrial-grade computing systems, it realizes automated control, data recording and analysis, fault alarms, and remote diagnostics for the entire production line, improving the level of intelligent production management.

[0057] like Figure 4 and Figure 5 As shown, preferably, the clamping device 60 is further provided with a clamping beam 64, a clamping vertical movement cylinder 65, and a clamping plate 66. The two ends of the clamping beam 64 are slidably connected to the main slide rail 15 of the main beam frame 14, the clamping vertical movement cylinder 65 is installed on the clamping beam 64, the clamping plate 66 is fixed to the piston end of the clamping vertical movement cylinder 65, and the plurality of clamping arms are respectively installed on the clamping plate 66.

[0058] Specifically, in order to improve the stability of the clamping device 60, it is preferable to set the main beam frame 14 as two supports arranged in parallel, and set two main slide rails 15 respectively, so that the clamping beam 64 can straddle the main beam frame 14 respectively.

[0059] like Figure 5 As shown, preferably, the clamping device 60 is further provided with a first clamping arm 61, a second clamping arm 62, and a third clamping arm 63. The clamping plate 66 is Z-shaped, with a first slide rail 67 and a first cylinder 68 at one end, and a second slide rail 69 and a second cylinder 610 at the other end. The first clamping arm 61 is slidably connected to the first slide rail 67 and forms a transmission connection with the piston end of the first cylinder 68. The second clamping arm 62 is slidably connected to the second slide rail 69 and forms a transmission connection with the piston end of the second cylinder 610. The third clamping arm 63 is fixed to the middle section of the clamping plate 66.

[0060] Specifically, the first clamping arm 61, the third clamping arm 63, and the second clamping arm 62 are arranged at a certain distance along the conveying direction of the material conveyor belt 11, and correspond to the ends of the three material conveyor belts 11 arranged side by side and at a certain distance, so that the corresponding clamping arms can clamp the material parked at the corresponding position.

[0061] Secondly, since the plastic inner bags opened by the bag-supporting device 40 are on the same parallel line, in order to insert the three materials into the three plastic inner bags at the same time, it is preferable to set a cylinder 610 at the first clamping arm 61 and the second clamping arm 62, so as to drive the first clamping arm 61 and the second clamping arm 62 to move to the part that is on the same parallel line as the third clamping arm 63.

[0062] like Figure 5 and Figure 8As shown, preferably, the bag supply device 20 is further provided with a bag supply beam 23, a bag supply vertical movement module 24, a bag supply motor 25, and a bag supply main plate 26. The two ends of the bag supply beam 23 are slidably connected to the main slide rail 15 of the main beam frame 14. The bag supply vertical movement module 24 and the bag supply motor 25 are respectively installed on the bag supply beam 23, and the bag supply vertical movement module 24 is drivenly connected to the bag supply motor 25. The bag supply main plate 26 is fixed to one end of the bag supply vertical movement module 24 and is provided with multiple sets of bag supply suction cups 22.

[0063] Specifically, similarly, the bag supply beam 23 also straddles the main slide rail 15 of the main beam frame 14. The bag supply motor 25 is preferably a stepper motor or a geared motor, and the bag supply vertical movement module 24 can be a KNK5008 linear module, so that under the drive of the bag supply motor 25, the bag supply vertical movement module 24 can drive the bag supply plate 26 to move linearly in the vertical direction.

[0064] like Figure 8 and Figure 9 As shown, preferably, the bag supply device 20 is further provided with a box input conveyor belt 30, an empty box output conveyor belt 31, a box lateral movement mechanism 34, and a box stabilizing cylinder 32. The box input conveyor belt 30 is used to transport the bag supply box 21 filled with plastic inner bags to the box lateral movement mechanism 34. The box lateral movement mechanism 34 moves the bag supply box 21 to the starting end of the empty box output conveyor belt 31. Two sets of box stabilizing cylinders 32 are respectively installed on both sides of the empty box output conveyor belt 31 and fix the bag supply box 21 at the starting end of the empty box output conveyor belt 31.

[0065] Specifically, the housing stabilizing cylinder 32 allows the bag supply suction cup 22 to easily adsorb the plastic inner bag inside the bag supply box 21. The piston end of the housing stabilizing cylinder 32 is also equipped with a right-angle fork 33, which, driven by the housing stabilizing cylinder 32, can fork the corner of the bag supply box 21, thereby limiting the bag supply box 21 and making it stably stop at the starting end of the empty box output conveyor belt 31.

[0066] Secondly, after all the plastic inner bags inside the bag supply box 21 have been grabbed and removed, the box stabilizing cylinder 32 can retract the right-angle fork 33, releasing the limiting effect on the bag supply box 21. This allows the remaining empty boxes to move a certain distance to the output end of the empty box output conveyor belt 31 under the drive of the empty box output conveyor belt 31, thereby freeing up the starting position of the empty box output conveyor belt 31. This allows the box lateral movement mechanism 34 to move another bag supply box 21 filled with plastic inner bags to this position for the supply of plastic inner bags.

[0067] Furthermore, corresponding sensors (not shown in the figure) can be set at appropriate positions at the beginning of the empty box output conveyor belt 31 to detect whether all the plastic inner bags inside the bag supply box 21 have been grabbed and removed, thereby feeding back corresponding signals to the control device (not shown in the figure), so that the control device can operate to release the empty box and move a fully loaded bag supply box 21 to the corresponding position.

[0068] like Figure 8 As shown, preferably, the box body transverse movement mechanism 34 includes a box body transverse movement module 35, a box body motor 36, a box body cylinder 37, and a box body gripper 38. The box body gripper 38 is fixedly connected to the piston end of the box body cylinder 37. The box body cylinder 37 is slidably connected to the box body transverse movement module 35. The box body transverse movement module 35 is drivenly connected to the box body motor 36. The box body gripper 38 is also provided with a box body suction cup 39, which is used to adsorb the supply bag box 21.

[0069] Specifically, firstly, the suction cup 39 of the box body adsorbs the side wall of the bag supply box 21. Then, the box body cylinder 37 pushes the adsorbed bag supply box 21 outward a certain distance to facilitate its lateral movement. Then, the box body motor 36 operates, driving the box body lateral movement module 35 to operate, which in turn drives the box body gripper 38 to move the bag supply box 21 laterally, thereby moving the bag supply box 21 fully loaded with plastic inner bags to the starting end of the empty box output conveyor belt 31.

[0070] like Figure 7 As shown, preferably, the bag-supporting device 40 is further provided with a bag-inserting cylinder 45, a bag-inserting slide rail 46, and a support rod plate 50. The support rod plate 50 is slidably connected to the bag-inserting slide rail 46 and forms a transmission connection with the piston end of the bag-inserting cylinder 45. Multiple sets of support rod assemblies 41 are respectively installed on the support rod plate 50.

[0071] Specifically, when the bag insertion cylinder 45 operates, it can drive the support rod plate 50 to move along the bag insertion slide rail 46, thereby inserting it in the direction of the plastic inner bag picked up by the bag suction cup 22, and causing the bag support strip 44 to be inserted into the inside of the plastic inner bag and to open it up.

[0072] like Figure 7 As shown, preferably, the bag-supporting device 40 is further provided with a support rod slide rail 51, a support rod motor 52, and a support rod timing belt 53. The support rod slide rail 51 and the support rod motor 52 are respectively fixed to the support rod assembly plate 50. One end of the support rod timing belt 53 is rotatably connected to the support rod assembly plate 50, and the other end is drively connected to the support rod motor 52. The support rod assembly 41 is provided with a first vertical plate 42 and a second vertical plate 43. One end of the first vertical plate 42 is fixed to the first belt 54 of the support rod timing belt 53, and one end of the second vertical plate 43 is fixed to the second belt 55 of the support rod timing belt 53.

[0073] Specifically, when the strut synchronous belt 53 is mounted on the synchronous pulley and the drive end of the strut motor 52 and rotates, it can form a first belt 54 located above and a second belt 55 located below. The vertical plate of the strut assembly 41 can also form a first vertical plate 42 located on the left and a second vertical plate 43 located on the right. Therefore, the first vertical plate 42 can be fixed to the first belt 54 and the second vertical plate 43 can be fixed to the second belt 55, or the first vertical plate 42 can be fixed to the second belt 55 and the second vertical plate 43 can be fixed to the first belt 54. As long as the two vertical plates are fixed to different belts on the upper and lower sides respectively, the strut synchronous belt 53 can be driven to rotate when the strut motor 52 is running, so that the first belt 54 and the second belt 55 will move towards each other, and then the first vertical plate 42 and the second vertical plate 43 will move towards each other synchronously along the strut slide rail 51, forming two movement modes of separation or closure, realizing two operations of opening and closing the plastic inner bag.

[0074] like Figure 7 As shown, preferably, the first vertical plate 42 and the second vertical plate 43 are respectively provided with a bag support strip 44 at the end away from the support rod synchronous belt 53. The bag support strip 44 is provided with two strips spaced at a certain distance in the vertical direction, so that after the plastic inner bag is opened, an opening with a certain width and height is formed.

[0075] Specifically, the opening of the plastic inner bag faces the clamping device 60, allowing the clamping arms of the clamping device 60 to grip the material and insert it into the plastic inner bag through the opening. The bag-supporting strip 44 is preferably made of a material with a certain degree of elasticity and flexibility, so that it will not cause the inner bag to tear when it is opened.

[0076] like Figures 1 to 4 As shown, in another embodiment, the present invention also provides a fully automated production line, including a feeding device, a transfer device 71, a transfer device 80, and a pad printing device 90 arranged along a main conveyor belt 70. The feeding device is used to move the workpieces to be printed and place them on the transfer device 71. The transfer device 71 is used for temporary storage and transfer of the workpieces to be printed. The pad printing device 90 is used for performing a preset pad printing operation on the workpieces to be printed. The transfer device 80 is used to move the workpieces to be printed on the transfer device 71 to the pad printing device 90, or to move the workpieces that have been pad printed on the pad printing device 90 to the main conveyor belt 70. The main conveyor belt 70 then conveys the workpieces to an automatic bagging device for bagging, and then performs an unloading operation.

[0077] Specifically, the feeding equipment is equipped with a feeding robotic arm 78 and a feeding suction cup 79 to pick up the materials inside the outer box and move them to the transfer equipment 71. The transfer equipment 71 is equipped with a transfer fixture 72 and a fixture turntable 73. Multiple transfer fixtures 72 are evenly distributed on the fixture turntable 73, which can be rotated by a motor to rotate the transfer fixtures 72 in different directions, facilitating the receiving or supply of materials. The pad printing equipment 90 is equipped with a corresponding pad printing head and a pad printing mechanism. The pad printing head picks up the ink pattern to be transferred from the pad printing mechanism and then transfers it to the corresponding part of the material. When multiple patterns need to be transferred onto the material, multiple pad printing heads can be set up to perform different pattern transfer operations on different positions.

[0078] Secondly, the pad printing equipment 90 is also provided with a pad printing turntable 91, and multiple pad printing fixtures 92 are evenly distributed on the outer periphery of the pad printing turntable 91, so as to transport the material between the loading station 95, the pad printing station 96 and the unloading station 97.

[0079] Furthermore, in order to improve the overall pad printing efficiency of the pad printing production line, multiple sets of feeding equipment, transfer equipment 71, transfer equipment 80 and pad printing equipment 90 can be set up so that multiple materials can be pad printed simultaneously on both sides of the main conveyor belt 70.

[0080] like Figure 2 and Figure 3 As shown, preferably, the material transfer device 80 includes a material transfer robotic arm 81, a material transfer bracket 82, a material transfer nozzle 83, a nozzle cylinder 84, a material transfer finger 85, and a finger cylinder 86. The material transfer bracket 82 is fixed to the wrist movement end of the material transfer robotic arm 81, the nozzle cylinder 84 is fixed to one end of the material transfer bracket 82, and the material transfer nozzle 83 is fixed to the piston end of the nozzle cylinder 84. The finger cylinder 86 is fixed to the other end of the material transfer bracket 82, and the material transfer finger 85 is fixed to the piston end of the finger cylinder 86.

[0081] Specifically, the transfer nozzle 83 and the transfer finger 85 are set at a certain distance from each other and correspond to the loading station 95 and unloading station 97 on the pad printing equipment 90. That is, the transfer nozzle 83 picks up a piece to be transferred from the transfer device 71, and then moves it to the pad printing fixture 92 of the loading station 95 under the drive of the transfer robotic arm 81. Then, the transfer robotic arm 81 drives the transfer bracket 82 to move downward, so that the transfer nozzle 83 places the piece to be transferred on the pad printing fixture 92 of the loading station 95. At the same time, the transfer finger 85 at the other end of the transfer bracket 82 is also driven to move downward synchronously and is located on both sides of the pad printing fixture 92 of the unloading station 97, so that the finger cylinder 86 operates and drives the transfer finger 85 to clamp the piece to be removed placed on the pad printing fixture 92 of the unloading station 97. Subsequently, the transfer robotic arm 81 drives the transfer bracket 82 to move upward and moves the gripped material towards the main conveyor belt 70, so that the transfer fingers 85 place the gripped material on the main conveyor belt 70 for conveying.

[0082] Secondly, on both sides of the pad printing fixture 92 at the loading station 95, there are also limiting push plates 93 and limiting cylinders 94. The limiting push plates 93 are fixed to the piston end of the limiting cylinders 94, so that the pad printing fixture 92 at the loading station 95 is clamped under the operation drive of the limiting cylinders 94, and is limited to a preset position, so that the material suction nozzle 83 can place the sucked material onto the pad printing fixture 92.

[0083] like Figure 1 and Figure 4 As shown, preferably, a vision inspection device 74 is also provided between the main conveyor belt 70 and the automatic bagging equipment. The vision inspection device 74 is equipped with a vision robotic arm 75, a vision lens 76, and a vision suction cup 77. The vision lens 76 performs visual inspection on the materials and determines whether the pad printing effect on the materials meets the production requirements. The vision suction cup 77 can pick up the materials, and then the vision robotic arm 75 moves the qualified materials to the material conveyor belt 11 of the automatic bagging equipment. Alternatively, the unqualified materials can be moved to the defective product recycling station (not shown in the figure) for defective product recycling.

[0084] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
