Description

Technical Field

[0001] The present invention relates to the technical field of palletizing devices, and more specifically to an intelligent auxiliary palletizing device for material transportation. Background Art

[0002] Auxiliary palletizing devices for material transportation are usually called palletizing robots or palletizers. Their components and workflow are crucial to achieving efficient and accurate material palletizing. Common palletizing devices are mainly composed of gripper mechanisms, positioning devices, lifting mechanisms, power supply devices, and control systems. The specific process of material transportation by the palletizing device is as follows: under the action of the power supply device and the control system, the lifting mechanism drives the gripper mechanism to grab the material, and the next step is to transport the material under the action of the lifting mechanism and the control system; In actual operation, we found that the gripper mechanism cannot adapt to materials of various specifications. The main reasons for the above are: many mechanical gripper mechanisms are special grippers designed for specific products or production lines. When the size, shape and other parameters of the transported object change, the special gripper mechanism may not be able to adapt to such changes well. This leads to the need to replace or adjust the mechanical gripper when changing products or adjusting the production process on the production line, thus increasing production costs and complexity; Therefore, we are in urgent need of an intelligent auxiliary stacking device for material transportation to solve the above-mentioned technical problems. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an intelligent auxiliary stacking device for material transportation to solve the problems existing in the above-mentioned background technology.

[0004] The present invention provides the following technical solution: an intelligent auxiliary palletizing device for material transportation, comprising: A working platform, wherein a control system is provided inside the working platform; Auxiliary stacking device, used for stacking materials, wherein the auxiliary stacking device is installed on one side of the upper surface of the working platform, and an escalator is installed on the side of the auxiliary stacking device for the staff to maintain and repair it, and a lifting mechanism is installed at the bottom of the auxiliary stacking device away from the escalator, and a connecting bracket is installed at the output end of the lifting structure; The transport mechanism is used for transporting materials, wherein the transport mechanism is installed on the upper surface of the working platform and is also installed at the bottom of the lifting mechanism and the connecting bracket to facilitate the stacking and transportation of materials; A main mounting plate is vertically mounted at the bottom of the connecting bracket, and a data acquisition device is mounted at the geometric center of the bottom surface of the main mounting plate, wherein the data acquisition device is connected to the control system, and the data acquisition device collects two-dimensional image data of the material in a top-down manner and transmits it to the control system for monitoring the length and width data of the material and detecting the transportation status of the material.

[0005] Furthermore, cross beams are fixedly installed on both sides of the bottom surface of the main mounting plate, and the installation positions of the two groups of cross beams are symmetrically distributed with the center line of the main mounting plate, auxiliary mounting plates are installed on the bottom surfaces of the two groups of cross beams, and the number of auxiliary mounting plates is two groups, wherein the center lines of the two groups of auxiliary mounting plates coincide with the center line of the main mounting plate, power mechanisms are installed on the sides of the upper surfaces of the two groups of auxiliary mounting plates, and a transmission mechanism is installed on the output end of the power mechanism for transmitting the power generated by the power mechanism, wherein the transmission mechanism moves through the interior of the auxiliary mounting plate.

[0006] Furthermore, protective plates are installed on the outer walls of both sides of the two groups of auxiliary mounting plates, and limiting plates are installed on both sides of the bottom surfaces of the auxiliary mounting plates, wherein the installation positions of the two groups of limiting plates are close to the protective plates adjacent to them, and the installation positions of the two groups of limiting plates are symmetrically distributed with the center lines of the auxiliary mounting plates. The center positions of the two groups of limiting plates are movably sleeved with transmission plates, and the outer wall of the center position of the transmission plate is fixedly installed inside one end of the transmission mechanism away from the power mechanism position. The power mechanism inputs a stable working current to generate a corresponding power source, and the transmission plate is driven to rotate inside the limiting plate through the transmission of the transmission mechanism.

[0007] Furthermore, the transmission plate is provided with a first mounting plate on the bottom side surface near the geometric center points of the two groups of auxiliary mounting plates, and two groups of slide grooves are provided on the inner wall of the first mounting plate, and the two groups of slide grooves are symmetrically distributed with respect to the center line of the first mounting plate, and a slider matching it is sleeved inside each group of slide grooves, wherein the number of sliders is multiple, and a connecting rod assembly is installed on the side surface of each slider near the slide groove position to form an overall synchronous movement system, and a first transmission screw is movably sleeved on the center position of a slider away from the center line position of the first mounting plate, and placement holes are provided at the center positions of the remaining sliders, wherein the geometric center points of the first transmission screw and the placement holes are on the same straight line, and the inner diameter length of the first transmission screw is smaller than the inner diameter length of the input hole, thereby ensuring that the movement trajectory of the remaining sliders is not affected during the rotation operation of the first transmission screw.

[0008] Further, a servo motor is installed at one end of the first transmission screw away from the position of the slider, and the servo motor is installed on the inner walls of both sides of the first mounting plate, and a gripper is installed on the side of the slider away from the position of the linkage rod assembly, and a telescopic plate is installed on the inner wall of the first mounting plate close to the gripper, and the inner wall of the telescopic plate is installed on both sides of the slider; The inner wall of the protective plate is provided with a slide groove, which runs from one side of the protective plate to the other side thereof, and the inner wall of the slide groove is movably sleeved with an auxiliary slider matched therewith, and a group of electric-controlled lifting devices are installed at the bottom of the auxiliary slider, and a second transmission screw is threadedly connected to the inner wall of the auxiliary slider, and a motor is installed at the end of the second transmission screw away from the auxiliary slider, and the motor is installed on the inner wall of one side of the protective plate, and another group of electric-controlled lifting devices is installed at the bottom of the other side of the protective plate, and a protective net is installed at the bottom of each group of electric-controlled lifting devices.

[0009] Furthermore, the motor inputs a stable current to drive the second transmission screw to rotate, driving a group of auxiliary sliders to move toward the installation position of the motor. At this time, the protective net is in a stretched state. Driven by each group of electric-controlled lifting devices, the protective net in the stretched state moves to the bottom of the two groups of grippers.

[0010] Furthermore, the control system includes an adjustment module, a protection module and an early warning module. After the adjustment module receives the two-dimensional image data of the material collected by the data acquisition device in a bird's-eye view, it analyzes the length of the material. After the analysis is completed, the adjustment module uploads the analyzed data to the control system. The control system drives the servo motor to input corresponding current to adjust the distance between each gripper to a distance suitable for the material.

[0011] Furthermore, when the protection module simulates the material in a normal placement state, the data acquisition device generates simulated two-dimensional image data, and the protection module compares the real-time two-dimensional image data with the simulated two-dimensional image data. When the deviation between the two exceeds 20%, it is judged that the material is in a position offset or tilted state on the gripper surface. The control system drives the electric-controlled lifting device and the motor to input a stable working current to play a temporary protective role. The early warning module sends an early warning message to the on-site staff to remind them to check.

[0012] Technical effects and advantages of the present invention: 1. The present invention uses a control system to analyze the specific length data of the material based on the two-dimensional image data collected by the data acquisition device. After the analysis is completed, the control system starts each group of servo motors to input a stable working current. Each group of servo motors drives the first transmission screw to rotate, drives a slider to move to the position of the servo motor, and at the same time, under the action of the linkage rod assembly, drives the remaining sliders to move synchronously, thereby driving the distance between each gripper to change. After the grasping range generated by each gripper is adapted to the material, the servo motor stops inputting a stable working current, thereby solving the problem that the conventional gripper device cannot adapt to materials of different specifications, and reducing the cost of material transportation to a certain extent.

[0013] 2. The present invention can determine through the control system that when the material is in an inclined sliding state, the motor inputs a stable current to drive the second transmission screw to rotate, and drives a group of auxiliary slide blocks to move toward the installation position of the motor. At this time, the protective net is in a stretched state. Under the drive of each group of electric control lifting devices, the protective net in a stretched state moves to the bottom of the two groups of grippers, playing a temporary protective role, preventing the material from falling directly onto the surface of the working area, thereby causing certain harm to the on-site workers.

The intelligent auxiliary stacking device for material transportation according to claim 7, characterized in that: When the protection module simulates that the material is in a normal placement state, the data acquisition device (6) generates simulated two-dimensional image data. The protection module compares the real-time two-dimensional image data with the simulated two-dimensional image data. When the deviation between the two exceeds 20%, it is determined that the material is in a positional offset or tilted state on the surface of the gripper (410). The control system drives the electric-controlled lifting device (501) and the motor (503) to input a stable working current to play a temporary protective role. The warning module sends a warning message to the on-site staff to remind them to check.
