Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent cardboard gluing, and particularly relates to an intelligent cardboard gluing device. Background Art

[0002] An intelligent cardboard gluing device is an automated equipment integrating mechatronic control technology. Its core function is to achieve precise coating of glue through a multi-degree-of-freedom motion system. This device uses a multi-motor system for coordinated driving, combines motion control algorithms to perform trajectory planning on the end effector of the robotic arm, and can complete high-precision gluing operations in three-dimensional space.

[0003] However, there are some problems with the current intelligent cardboard gluing device when gluing cardboard: In the production workshop, due to reasons such as paper cutting and handling, the air may contain a large amount of dust. When the cardboard is being glued, the intelligent cardboard gluing device is in a high-dust environment. At this time, in the multi-motor system, when the motors are running, turbulence and eddy currents will form around them. When multiple motors are close to each other, these turbulence and eddy currents will interact with each other. The interaction between airflows may cause changes in the direction and speed of the airflows, resulting in unstable and interfering airflows. This may cause dust to spread more easily between the motors and electrical components. The airflow may carry dust to various parts of the motor, including areas that are not easily cleaned. In view of this, an intelligent cardboard gluing device is proposed, which can optimize the problems brought by the multi-motor system while ensuring precise coating of glue through multi-degree-of-freedom motion.

Specific embodiments

[0028] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific embodiments, structures, features and their effects of the present invention.

[0029] Please refer to Figure 1 - Figure 6As shown in the figure, this embodiment provides an intelligent cardboard gluing device, which includes an intelligent control system, a support part 1, a planetary gear part 2, a U-shaped rotating part 3, an electric drive swinging part 4, an L-shaped sliding part 5, a driving part 6, a bevel gear set 7, a conical sliding part 8 and a gluing part 9. The planetary gear part 2, the U-shaped rotating part 3, the electric drive swinging part 4 and the L-shaped sliding part 5 are all arranged on the support part 1. The driving end of the driving part 6 is connected to the sun gear 22 of the planetary gear part 2 through a first rotating shaft 12. One bevel gear shaft of the bevel gear set 7 is connected to one vertical rod end of the U-shaped rotating part 3, and the other bevel gear shaft of the bevel gear set 7 is connected to one end of the cross bar of the U-shaped rotating part 3. Both ends of the conical sliding part 8 are switchably fitted between the sun gear 22 and the other end of the cross bar of the U-shaped rotating part 3, and are linked with the electric drive swinging part 4 through the L-shaped sliding part 5. The gluing part 9 is connected to the output end of the bevel gear set 7. The driving part 6 cooperates with the electric drive swinging part 4 through the intelligent control system to enable multi-degree-of-freedom motion switching of the gluing part 9.

[0030] It should be noted that when the electric drive swinging part 4 drives the L-shaped sliding part 5 to slide horizontally along the support part 1, the L-shaped sliding part 5 drives the conical sliding part 8 to slide and cooperate with the sun gear 22 of the planetary gear part 2 as a whole. The main shaft of the driving part 6 rotates to drive the conical sliding part 8 to rotate, the conical sliding part 8 drives the sun gear 22 of the planetary gear part 2 to rotate, the sun gear 22 of the planetary gear part 2 drives the planetary gear 23 of the planetary gear part 2 to rotate, the planetary gear 23 drives the U-shaped rotating part 3 to revolve around the main shaft, and the U-shaped rotating part 3 drives the bevel gear set 7 and the gluing part 9 to rotate synchronously, so that the gluing part 9 applies glue along the X and Y axis trajectories in the cardboard plane; when the electric drive swinging part 4 drives the L-shaped sliding part 5 to slide in the reverse direction, the conical sliding part 8 and the end of the cross bar of the U-shaped rotating part 3 are fitted as a whole. The main shaft of the driving part 6 rotates to drive the cross bar of the U-shaped rotating part 3 to rotate. The cross bar of the U-shaped rotating part 3 drives the bevel gear set 7 for orthogonal transmission, and the bevel gear set 7 drives the gluing part 9 to rotate around its own axis, so that the gluing part 9 realizes glue application along the Z-axis three-dimensional trajectory. In this way, multi-degree-of-freedom motion switching of the gluing part 9 is realized through a single motor.

[0031] One further point to be added is that the control of the electric control system involved in the above text includes motion mode switching control and dust suppression collaborative control. In the motion mode switching control, the intelligent control system receives the glue application trajectory instruction, such as planar glue application or three-dimensional edge wrapping. Through the preset algorithm, it is parsed into a motion mode signal. In the X / Y axis mode or Z axis mode, the control system real-time monitors the displacement sensor signal of the L-shaped sliding part 5 to ensure that the conical sliding part 8 is engaged with the sun gear 22 in place. If a deviation is detected, the deviation correction program is triggered to fine-tune the pulse number of the stepping motor of the electric drive swing part 4; in the Z axis three-dimensional glue application mode, the control system feedbacks the rotation angle of the glue application part 9 through the encoder and dynamically adjusts the spindle speed to ensure the uniformity of the Z axis glue application thickness; in the dust suppression collaborative control, during the gap when the glue application part 9 switches the motion mode, the intelligent control system reduces the spindle speed of the drive part 6 to reduce the air flow impact generated by the movement of mechanical components. At the same time, it starts the negative pressure dust suction module built in the support part 1 to adsorb suspended dust. An optical fiber dust sensor is installed at the meshing interface between the conical sliding part 8 and the planet gear 23 / cross bar to real-time monitor the dust concentration. If it exceeds the standard, the following actions are triggered: increasing the power of the negative pressure dust suction module to the maximum value, pausing the glue application operation and starting the self-cleaning program, and the L-shaped sliding part 5 reciprocates multiple times to remove the dust attached to the meshing surface by mechanical friction. Except for the above description, the parts not described in the above control logic are the prior art parts. The data settings in the control system here need to be set according to the specific size, shape and other specific characteristics of the cardboard during actual operation.

[0032] Since there are some problems in the current intelligent cardboard glue application device when applying glue to cardboard. For example, in the production workshop, due to reasons such as paper cutting and handling, the air may contain a large amount of dust. When the cardboard is being glued, the intelligent cardboard glue application device is in a high-dust environment. At this time, in the multi-motor system, when the motor is running, turbulence and eddy currents will be formed around it. When multiple motors are close to each other, these turbulence and eddy currents will interact with each other. The interaction between airflows may cause changes in the airflow direction and speed, resulting in unstable and interfering airflows. This may cause dust to spread more easily between the motors and electrical components. The airflow may carry the dust to various parts of the motor, including areas that are not easily cleaned.

[0033] To solve the above problems, in this embodiment, by adopting the power transmission of a single driving part 6 in cooperation with the planetary gear part 2, the bevel gear set 7 and the conical sliding part 8, the traditional multi-motor separate control mode is replaced, fundamentally eliminating the turbulent superposition effect generated during the operation of multiple motors, reducing the carrying effect of air flow disorder on dust, and making it difficult for dust to form a diffusion path around the motor; the movement mode of the gluing part 9 is switched through the mechanical linkage between the conical sliding part 8 and the L-shaped sliding part 5, the plane X / Y axis and the three-dimensional Z axis, avoiding local air flow disturbance caused by frequent start and stop of multiple motors, while reducing the number of electrical interfaces and the risk of dust intrusion into sensitive areas such as motor bearings and circuit boards; the intelligent control system dynamically adjusts the action frequency of the electric drive swing part 4 based on the gluing trajectory requirement, making the mechanical movement coordinated with the air flow change, further suppressing dust dispersion. The single-motor drive and the mechanical structure coordinated switching design solve the problem of dust diffusion caused by air flow interference in the multi-motor system in a high-dust environment.

[0034] Since it is for gluing cardboard, the current intelligent cardboard gluing device realizes multi-degree-of-freedom movement through the coordinated drive of a multi-motor system for precise coating. Therefore, in the design, not only the multi-degree-of-freedom movement but also the precise coating need to be considered. In an embodiment, the planetary gear part 2 includes a gear ring 21 fixedly arranged on the support part 1, a sun gear 22 arranged at the center of the gear ring 21, and planetary gears 23. The planetary gears 23 are respectively meshed with the sun gear 22 and the gear ring 21, and the diameters of the sun gear 22 and the planetary gears 23 are equal. Since the diameters of the sun gear 22 and the planetary gears 23 are equal, this enables the planetary gears 23 to mesh more precisely with the sun gear 22 and the gear ring 21, thereby reducing the clearance and friction during the transmission process. In addition, in the planetary gear system, the planetary gears 23 are evenly distributed around the sun gear 22, and the diameters of the sun gear 22 and the planetary gears 23 are equal. The planetary gears 23 are evenly distributed and embedded in the gear ring 21 to form a semi-closed structure, reducing the probability of dust entering the meshing area.

[0035] It is worth mentioning that when gluing the cardboard, a single driving part 6 is used to achieve power transmission, replacing the traditional multi-motor separate control mode. Generally, it involves multiple link components. However, when gluing the cardboard in batch operation, when any action is performed by the multiple link components, they need to be linked together, which exacerbates the wear of the link components. To reduce unnecessary linkage, in an embodiment, both ends of the conical sliding part 8 are switchably fitted between the sun gear 22 and the other end of the cross bar of the U-shaped rotating part 3, and are linked with the electric drive swing part 4 through the L-shaped sliding part 5. The conical sliding part 8 includes two conical connection blocks 81, and the two conical connection blocks 81 are connected by a second rotating shaft 82. Conical sleeves 10 are provided on both the sun gear 22 and the other end of the cross bar of the U-shaped rotating part 3. The two conical connection blocks 81 are tightly pressed and fitted with one of the conical sleeves. The conical sleeve 10 and the conical connection block 81 are both made of carbon fiber reinforced composite material with a high friction coefficient. The second rotating shaft 82 between the two conical connection blocks 81 is made of tungsten carbide with a low friction coefficient. When the conical sleeve 10 and the conical connection block 81 are tightly pressed and fitted, it is necessary to ensure that the first rotating shaft 12 can drive the conical sleeve 10 and the conical connection block 81 to rotate together, and at the same time, the stiffness needs to be ensured. Therefore, the conical sleeve 10 and the conical connection block 81 are both made of carbon fiber reinforced composite material with a high friction coefficient. The second rotating shaft 82 between the two conical connection blocks 81 not only needs to cooperate with the arc-shaped clamping ring 53 mentioned below to stably support, but also needs to ensure that when the second rotating shaft 82 rotates synchronously with the two conical connection blocks 81, it will not interfere with the arc-shaped clamping ring 53. Therefore, the second rotating shaft 82 between the two conical connection blocks 81 is made of tungsten carbide with a low friction coefficient. The carbon fiber reinforced composite material with a high friction coefficient has excellent wear resistance and can maintain stable performance in high-load and friction environments. Tungsten carbide, as a material with a low friction coefficient, has high hardness and good wear resistance and is suitable for use as a rotating shaft.

[0036] To ensure that the L-shaped sliding part 5 can only slide in the horizontal direction, the L-shaped sliding part 5 can not only drive the two ends of the conical sliding part 8 to be switchably fitted between the sun gear 22 and the other end of the cross bar of the U-shaped rotating part 3, but also provide a support for the conical sliding part 8 and avoid interference between the two motions. In this regard, in one embodiment, the L-shaped sliding part 5 includes an L-shaped rod 51 and a movable rod 52 vertically arranged at the corner of the L-shaped rod 51. The movable rod 52 penetrates through the corner of the L-shaped rod 51. The cross bar of the L-shaped rod 51 horizontally slides through the support part 1. The end of the vertical rod of the L-shaped rod 51 is rotatably connected to the second rotating shaft 82 through an arc-shaped snap ring 53. The design of the L-shaped sliding part 5 allows for more flexible and stable lateral and longitudinal movements. The connection between the arc-shaped snap ring 53 and the second rotating shaft 82 provides stable support and avoids jitter and displacement during movement, thus ensuring the accuracy of glue application. The second rotating shaft 82 and the first rotating shaft 12 are connected as a whole. The sun gear 22 of the planetary gear part 2 is rotatably connected to the first rotating shaft 12. The design of connecting the second rotating shaft 82 and the first rotating shaft 12 as a whole simplifies the structure and reduces possible fault points.

[0037] To ensure that precise coating of the rubber material can be achieved through multi-degree-of-freedom motion while also avoiding loss of precision, in one embodiment, the electric drive swing part 4 includes an electric telescopic rod, a swing telescopic rod 41, a connecting rod 42, and a guide block 43. The electric telescopic rod is horizontally arranged on the support part 1. The two ends of the connecting rod 42 are respectively connected to one end of the swing telescopic rod 41 and the guide block 43. One end of the swing telescopic rod 41 is perpendicular and fixedly connected to the connecting rod 42. The other end of the swing telescopic rod 41 is hinged to the output end of the electric telescopic rod. A guide groove 431 is provided on the guide block 43, and the movable rod 52 is movably arranged in the guide groove 431. The electric telescopic rod drives the swing telescopic rod 41 to swing through the hinge; among them, the electric telescopic rod is not drawn in the figure because the position of the electric telescopic rod here can be set according to the actual situation, as long as it can drive the swing telescopic rod 41 to rotate.

[0038] Furthermore, in one embodiment, the U-shaped rotating part 3 is connected to the support part 1 through a support frame 11. The support frame 11 and the U-shaped rotating part 3 are rotatably connected. The end of the cross bar of the L-shaped rod 51 slidably penetrates through the support frame 11. The rotational connection between the U-shaped rotating part 3 and the support frame 11 increases the reliability of the connection and is also convenient for maintenance and replacement.

[0039] Furthermore, in an embodiment, a spring 31 for assisting the reset of the conical connection block 81 is arranged between the crossbar end of the L-shaped rod 51 and the side wall of the support frame 11. The two ends of the spring 31 are respectively connected to the side wall of the support frame 11 and the crossbar end of the L-shaped rod 51. The spring 31 is arranged between the crossbar end of the L-shaped rod 51 and the side wall of the support frame 11 to assist the reset of the conical connection block 81, which not only simplifies the operation but also reduces manual intervention during the operation and improves the automation degree of the equipment.

[0040] The working process and principle of the present invention:

[0041] Through the mechanical linkage of the single driving part 6, the planetary gear part 2, the bevel gear set 7 and the conical sliding part 8, the precise switching of the multi-degree-of-freedom movement of the gluing part 9 is realized. Under the X / Y-axis trajectory of the planar gluing mode, the electric drive swinging part 4 drives the L-shaped sliding part 5 to slide horizontally, driving the conical sliding part 8 to mesh with the sun gear 22 of the planetary gear part 2. At this time, the main shaft of the driving part 6 drives the conical sliding part 8 to rotate through the first rotating shaft 12, and the sun gear 22 drives the planetary gear 23 to revolve around the ring gear 21 accordingly. The planetary gear 23 drives the U-shaped rotating part 3 to rotate around the main shaft, and then synchronously drives the gluing part 9 to perform a composite circular motion in the cardboard plane through the bevel gear set 7 to form X / Y-axis trajectory gluing. When switching to the three-dimensional gluing mode Z-axis trajectory, the electric drive swinging part 4 reversely drives the L-shaped sliding part 5 to disengage the conical sliding part 8 from the sun gear 22 and tightly engage it with the conical sleeve 10 at the end of the crossbar of the U-shaped rotating part 3. At this time, the main shaft of the driving part 6 directly drives the U-shaped crossbar to rotate through the second rotating shaft 82, and the bevel gear set 7 orthogonally transmits the power to the gluing part 9 to drive it to rotate at a high speed around its own axis, and combines with the lifting mechanism to realize spiral three-dimensional edge gluing;

[0042] The intelligent control system monitors the position of the L-shaped sliding part 5 in real time through a displacement sensor, and dynamically adjusts the stepping pulse of the electric drive swinging part 4 to ensure the precise meshing of the conical sliding part 8; the encoder feedbacks the rotation angle of the gluing part 9, and the main shaft speed is closed-loop controlled to maintain the uniformity of the Z-axis gluing thickness. In terms of dust suppression, the main shaft speed is reduced during the mode switching interval to reduce air flow disturbance, and the negative pressure dust suction module is synchronously started to adsorb suspended dust; when the fiber optic sensor detects that the concentration of the meshing surface exceeds the standard, the self-cleaning program is triggered to make the L-shaped sliding part 5 perform high-frequency reciprocating motion, and the mechanical friction of the carbon fiber conical block is used to remove dust;

[0043] The semi-closed structure in which the planet gear 23 meshes with the sun gear 22 with equal diameters reduces dust intrusion. The combination of the carbon fiber conical connecting block 81 and the tungsten carbide rotating shaft takes into account both transmission reliability and low wear. The integrated design of the arc-shaped clamping ring 53 at three points of the L-shaped sliding part 5 and the second rotating shaft ensures the movement stability. The spring 31 at the end of the cross bar assists in resetting, which improves the degree of automation. The single-motor drive combined with mechanical linkage switching eliminates the airflow interference of multiple motors. At the same time, through material optimization and intelligent collaborative control, it ensures high gluing accuracy and dust suppression rate in a high-dust environment.

[0044] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
