Description

Technical Field

[0001] This invention relates to the field of paper box manufacturing technology, and in particular to a three-axis decorative box assembly equipment. Background Technology

[0002] Decorative boxes are often made of materials such as cardboard, wood, and plastic. The assembly process of decorative boxes often uses a three-axis assembly machine, which is driven by cylinders. One cylinder completes the movement of one axis. By assembling the three cylinders, a three-degree-of-freedom Cartesian coordinate system assembly machine is formed to complete the movement of the X, Y, and Z axes, thereby accurately assembling the box body and frame of the decorative box.

[0003] The assembly and molding equipment in the prior art CN202110534621.8 includes a bottom support device. One end of the bottom support device is equipped with an outer box feeding device. A damping rod is movably connected to the inner wall of the outer shell stamping part. An outer box gluing device is provided between the outer box feeding device and the drying device. The outer box gluing device includes an outer box handling robot and a gluing robot. The other end of the bottom support device is equipped with an inner and outer box assembly and molding device.

[0004] The aforementioned structure autonomously assembles the inner and outer boxes of the packaging box and outputs the completed packaging box to the unloading device. However, during the assembly process, due to inaccurate control of the air intake volume or intake speed of the cylinder, the speed is too fast when placing the box, resulting in excessive impact between the lid and the box body. This causes excessive pressure on the box body, leading to phenomena such as the box body shifting off-center due to impact, the lid denting, or the box body deforming. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a three-axis decorative box assembly device to solve the problem that during assembly, the impact of the box lid on the box body is too great, resulting in the box body shifting off-center due to impact, the box lid denting, or the box body deforming.

[0006] To achieve the above objectives, the present invention provides a three-axis decorative box assembly device, including a machine body and a conveyor table installed on one side of the machine body. A side plate is fixedly installed on one side of the machine body, a longitudinal beam is fixedly installed on the top of the side plate, and a conveyor belt is provided on one side of the longitudinal beam. The conveyor belt is driven by a motor fixedly installed on one side of the side plate. A linear bearing module is slidably installed on the conveyor belt, and a vertical beam and an assembly cylinder are simultaneously installed on the linear bearing module.

[0007] The output end of the assembly cylinder is connected to a guide rail, and the end of the guide rail is connected to a crossbeam. The two ends of the crossbeam are respectively equipped with a gripper cylinder and a suction cup cylinder. The gripper cylinder is used to assemble the decorative box. The end of the suction cup cylinder is provided with a connector, which includes a vacuum suction cup and is used to adsorb the decorative box.

[0008] The vertical beam is slidably mounted on top of the longitudinal beam, and a control module electrically connected to the connector is provided between the vertical beam and the longitudinal beam. The control module is used to change the force of the connector on the decorative box.

[0009] Preferably, the connector further includes a pressure plate fixedly connected to the output end of the suction cup cylinder. Multiple sets of upper bolts are fixedly installed on the pressure plate. A vacuum rod passes through the inside of each upper bolt. A lower bolt is fixedly connected to the bottom end of the vacuum rod. A vacuum suction cup is installed at the bottom end of the lower bolt.

[0010] Preferably, an electromagnet is installed inside the upper bolt, and an aluminum core is installed inside the vacuum rod.

[0011] Preferably, a spring is sleeved on the outside of the vacuum rod, with one end of the spring fixed to the upper bolt and the other end fixed to the outside of the vacuum rod.

[0012] Preferably, the control module includes a housing mounted at the bottom of the vertical beam, a sliding rheostat fixedly installed inside the housing, the sliding rheostat being electrically connected to an electromagnet, a connecting rod sleeved on the outside of the sliding rheostat, a telescopic spring sleeved on the outside of the connecting rod, and the connecting rod extending through the bottom of the housing into the longitudinal beam;

[0013] The longitudinal beam has deep holes and shallow holes corresponding to the connecting rod.

[0014] Preferably, the deep hole corresponds to the suction cup cylinder, and the shallow hole corresponds to the gripper cylinder.

[0015] Preferably, the bottom end of the stick is semi-circular, and the bottom end of the stick slides along the top of the longitudinal beam.

[0016] Preferably, the inner walls of the grippers are provided with rubber pads, and the width between the gripper cylinder and the decorative box is matched.

[0017] The beneficial effects of this invention are as follows: By assembling the cylinder to drive the guide rail downward, the guide rail and the gripper cylinders and suction cup cylinders at both ends are moved downward to above the box cover and box body to be assembled. After reaching the designated position, the gripper cylinder and suction cup cylinder are clamped and adsorbed by the connecting parts at the bottom of the gripper cylinder and suction cup cylinder respectively. After adsorption, the box returns. When the box cover moves above the box body, the control module reduces the force of the connecting parts and vacuum suction cup on the box cover to avoid excessive impact during adsorption and placement, which would cause damage to the whole. This effectively prevents the box body from deviating due to impact, the box cover from being dented, or the box body from being deformed. Finally, the box cover and box body are assembled. The whole process is efficient and fast. The cantilever three-axis assembly device is used to assemble the decorative box. The cantilever three-axis device has accurate positioning and can achieve precise gripping with high efficiency. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a three-axis decorative box assembly equipment includes a body 1 and a conveyor 23 installed on one side of the body 1. A side plate 2 is fixedly installed on one side of the body 1, and a longitudinal beam 3 is fixedly installed on the top of the side plate 2. A conveyor belt 14 is provided on one side of the longitudinal beam 3. The conveyor belt 14 is driven by a motor 8 fixedly installed on one side of the side plate 2. A linear bearing module 11 is slidably installed on the conveyor belt 14. A vertical beam 4 and an assembly cylinder 16 are also installed on the linear bearing module 11.

[0027] The output end of the assembly cylinder 16 is connected to the guide rail 15, and the end of the guide rail 15 is connected to the crossbeam 5. The two ends of the crossbeam 5 are respectively equipped with a gripper cylinder 9 and a suction cup cylinder 10. The gripper cylinder 9 is used to assemble the decorative box, and the end of the suction cup cylinder 10 is provided with a connector, which includes a vacuum suction cup 7. The connector is used to adsorb the decorative box.

[0028] The vertical beam 4 is slidably mounted on the top of the longitudinal beam 3. A control module electrically connected to the connector is provided between the vertical beam 4 and the longitudinal beam 3. The control module is used to change the force of the connector on the decorative box.

[0029] In this embodiment, the machine body 1 is equipped with multiple sets of box bodies 12 and box covers 13. Driven by the motor 8, the linear bearing module 11 moves to the left on the conveyor belt 14, thereby driving the entire device to move to the left. Then, the assembly cylinder 16 drives the guide rail 15 to move downward, driving the guide rail 15 and the gripper cylinders 9 and suction cup cylinders 10 at both ends to move downward above the box cover 13 and box body 12 to be assembled. After reaching the designated position, the gripper cylinder 9 and suction cup cylinder 10 are clamped and adsorbed respectively by the connecting parts at the bottom of the suction cup cylinder 10. After adsorption, the box cover 13 is moved to the top of the box body 12 and placed. At this time, the control module reduces the force of the connecting parts on the box cover 13 to avoid excessive impact during adsorption and placement, which may cause damage to the whole. Finally, the box cover 13 and box body 12 are assembled. After the assembly is completed, the gripper cylinder 9 drives the gripper 6 again, driving the entire decorative box to be clamped onto the conveyor table 23.

[0030] As one implementation method, such as Figure 3 , Figure 4 As shown, the connector also includes a pressure plate 24 fixedly connected to the output end of the suction cylinder 10. Multiple sets of upper bolts 20 are fixedly installed on the pressure plate 24. A vacuum rod 18 passes through the inside of the upper bolt 20. A lower bolt 19 is fixedly connected to the bottom end of the vacuum rod 18. A vacuum suction cup 7 is installed at the bottom end of the lower bolt 19.

[0031] In this embodiment, the lid 13 needs to be suctioned twice during the assembly process. The first time is when it is transferred to the assembly position. At this time, after the suction cylinder 10 drives the pressure plate 24 downward, when the suction cup 7 contacts the lid 13, the vacuum rod 18 is subjected to an upward elastic force, so that the vacuum suction cup 7 is suctioned to the lid 13. The second time is when it is assembled with the box body 12. During operation, when the suction cup 7 contacts the lid 13 and retracts, it is subjected to an upward elastic force due to the influence of the spring inside the upper bolt 20, thereby pushing the vacuum rod 18 to move upward within the bolt 25. This can avoid the lid 13 falling off or the assembly being incomplete during the assembly process.

[0032] As one implementation method, such as Figure 3 , Figure 4As shown, an electromagnet 21 is installed inside the upper bolt 20, and an aluminum core 22 is installed inside the vacuum rod 18.

[0033] In this embodiment, the current generated by the electromagnet 21 acts on the aluminum core 22 in the vacuum rod 18 to form electromagnetic damping. When the suction cup 7 contacts the lid 13, the upward elastic force on the vacuum rod 18 is reduced, making the vacuum suction cup 7 more stably attached to the lid 13.

[0034] As one implementation method, such as Figure 2 , Figure 4 As shown, a spring is sleeved on the outside of the vacuum rod 18. One end of the spring is fixed to the upper bolt 20, and the other end is fixed to the outside of the vacuum rod 18.

[0035] In this embodiment, a spring is provided in the suction cup structure. This spring plays a shock-absorbing and buffering role. In order to prevent the suction cup from having too much impact force when it retracts after contacting the cover 13 due to excessive air intake during the adsorption process, which may damage the equipment, the addition of the spring can greatly reduce this impact force and effectively protect the entire adsorption process and the equipment.

[0036] As one implementation method, such as Figure 5 As shown, the control module includes a housing 41 installed at the bottom of the vertical beam 4. A sliding rheostat 44 is fixedly installed inside the housing 41. The sliding rheostat 44 is electrically connected to the electromagnet 21. A stick 42 is sleeved on the outside of the sliding rheostat 44. A telescopic spring 43 is sleeved on the outside of the stick 42. The stick 42 extends through the bottom of the housing 41 into the longitudinal beam 3.

[0037] The longitudinal beam 3 has deep holes 45 and shallow holes 46 corresponding to the attached rod 42.

[0038] In this embodiment, the linear bearing module 11 moves to the left on the conveyor belt 14, thereby driving the entire device to move to the left. At the same time, the vertical beam 4 and the housing 41 move on the longitudinal beam 3, and the sticking rod 42 inside the housing 41 moves on the longitudinal beam 3 until the sticking rod 42 moves into the deep hole 45 or the shallow hole 46. The sliding rheostat 44 exhibits different resistance values, which affect the connecting parts and perform different clamping or adsorption operations.

[0039] As one implementation method, such as Figure 3 As shown, the deep hole 45 corresponds to the position of the suction cup cylinder 10, and the shallow hole 46 corresponds to the position of the gripper cylinder 9.

[0040] In this embodiment, when the vertical beam 4 and the housing 41 move along the longitudinal beam 3 into the deep hole 45, the resistance in the sliding rheostat 44 decreases, and the current flowing through the electromagnet 21 increases. The current generated by the electromagnet 21 acts on the aluminum core 22 in the vacuum rod 18 to form electromagnetic damping. When the suction cup 7 contacts the lid 13, the upward elastic force on the vacuum rod 18 decreases, making the adsorption between the vacuum suction cup 7 and the lid 13 more stable.

[0041] When the vertical beam 4 and the housing 41 move on the longitudinal beam 3 into the shallow hole 46, the resistance in the sliding rheostat 44 increases, the current flowing into the electromagnet 21 decreases, and the current generated by the electromagnet 21 acts on the aluminum core 22 in the vacuum rod 18. When the vacuum suction cup 7 contacts the cover 13 and retracts, it is affected by the spring inside the upper bolt 20 and receives an upward elastic force, so that the upward elastic force of the vacuum rod 18 is different at different positions.

[0042] As one implementation method, such as Figure 3 , Figure 5 As shown, the bottom end of the stick 42 is semi-circular, and the bottom end of the stick 42 slides along the top of the longitudinal beam 3.

[0043] In this embodiment, the vertical beam 4 and the housing 41 move on the longitudinal beam 3, and the sticking rod 42 inside the housing 41 moves on the longitudinal beam 3 until the sticking rod 42 moves to the deep hole 45 or the shallow hole 46 to perform different operations.

[0044] As one implementation method, such as Figure 2 , Figure 3 As shown, the inner walls of the grippers 6 are all provided with rubber pads 17, and the width between the gripper cylinder 9 and the box body 12 is matched.

[0045] In this embodiment, the gripper 6 prevents the box from failing to be gripped if there are items inside the box 12. Furthermore, rubber pads 17 are provided on both sides of the gripper 6 to prevent deformation of the box 12 due to excessive pressure caused by excessive air intake during gripping.

[0046] Working principle: In use, the entire three-axis decorative box assembly equipment is first driven by motor 8. The linear bearing module 11 moves to the left on the conveyor belt 14, thereby driving the entire device to move to the left. Then, the assembly cylinder 16 drives the guide rail 15 to move downward, driving the guide rail 15 and the gripper cylinders 9 and suction cup cylinders 10 at both ends to move downward above the box cover 13 and box body 12 to be assembled. After reaching the designated position, the vertical beam 4 and the shell 41 move on the longitudinal beam 3 to the deep hole 45. In the process, the resistance in the sliding rheostat 44 decreases, the current flowing into the electromagnet 21 increases, and the current generated by the electromagnet 21 acts on the aluminum core 22 in the vacuum rod 18 to form electromagnetic damping. When the vacuum suction cup 7 contacts the box cover 13, the upward elastic force on the vacuum rod 18 decreases, making the vacuum suction cup 7 and the box cover 13 more stable to adhere. The gripper cylinder 9 drives the gripper 6 to clamp the box body 12, and the suction cup cylinder 10 drives the suction cup 7 to adhere to the box cover 13. After clamping and adsorption are completed, the process returns.

[0047] Similar to the above path, after reaching the designated assembly position, the box is placed. After placement, the gripper cylinder 9 is not driven, and the suction cup cylinder 10 picks up the box cover 13 again. After the pick-up is complete, it moves to the left above the box body 12. At this time, the vertical beam 4 and the shell 41 move on the longitudinal beam 3 into the shallow hole 46. The resistance in the sliding rheostat 44 increases, and the current flowing into the electromagnet 21 decreases. The current generated by the electromagnet 21 acts on the aluminum core 22 in the vacuum rod 18. When the vacuum suction cup 7 contacts the box cover 13 and retracts, it is affected by the spring inside the upper bolt 20 and receives an upward elastic force, thereby pushing the vacuum rod 18 to move upward within the upper bolt 20. Finally, the box cover 13 and the box body 12 are assembled. After the assembly is completed, the gripper cylinder 9 drives the gripper 6 again, which drives the entire decorative box to be clamped onto the conveyor table 23.
