At the same time, the structural dimensions and position information of the spring and the wedge can be collected at any time during the operation of the industrial robot (1300), which is convenient for positioning and controlling the industrial robot;

[0054] 3. The industrial robot uses a six-axis industrial robot, which can design corresponding disassembly and assembly paths for pillow spring groups and wedges of different positions and sizes of different models of bogies, reducing the labor intensity on site and the potential safety hazards of on-site operations;

[0055] 4. In order to assist the disassembly and assembly of the inclined wedge of the industrial robot (1300), an inclined wedge bearing tooling is designed, which includes an F-shaped support plate, a rotating support shaft, a rolling bearing, a bidirectional swing cylinder, a load mounting seat and a load mounting plate; the two ends of the rotating support shaft are respectively connected to a rolling bearing, one end is connected to the F-shaped support plate, and the other end is connected to the bidirectional swing cylinder. The rotating support shaft and the two rolling bearings are installed together inside the load mounting seat so that the rotation of the F-shaped support plate can be controlled under the drive of the bidirectional swing cylinder. The structure is simple and compact, and the inclined wedge can be lifted, supported and moved before the pillow spring group is disassembled and installed;

[0056] 5. The six-axis industrial robot and the three-degree-of-freedom module use the industrial robot mounting base and the module mounting base respectively, and the mounting bases are fastened to each other, so that the industrial robot for automatic disassembly and assembly of the pillow spring and inclined wedge and the three-degree-of-freedom module unit for auxiliary disassembly and assembly of the inclined wedge are more stable and firm during the operation, which is convenient for the handling, positioning, care and maintenance of the equipment.

Installing the third row of pillow springs: the industrial robot (1300) moves to the designated position according to the motion command of the controller, controls the current on and off of the coil of the disassembly and assembly fixture (1100) and the movement of the cylinder, and sequentially takes out the third row of pillow springs from the preparation area and places them at the designated position in the side frame; after completing the installation of the third row of pillow springs, the mechanical arm of the industrial robot (1300) returns to the designated position; T3, Installation of the second row of wedges and pillow springs T31, machine vision sensor (1200) scanning: the end of the industrial robot (1300) moves to the front end of the pillow spring and the inclined wedge in the material preparation area, and the machine vision sensor (1200) scans the size and position information of the pillow spring and the inclined wedge, identifies the size and position information of the pillow spring and the inclined wedge by analyzing the point cloud data, and transmits the information to the host computer; T32, data transmission and data processing: the host computer obtains the size and position information of the parts for data processing, and sends the size and position information of the pillow spring and the inclined wedge to the industrial robot (1300) controller through the network port; the industrial robot (1300) controller assigns and calculates the motion instructions and parameters according to the size and position information of the pillow spring, and appropriately adjusts and optimizes the spatial point coordinate values ​​and motion instruction parameters of the default path to meet the installation operation of the second row of inclined wedges and pillow springs; T33. Install the second row of left-side bevel wedges and pillow springs: The host computer drives the three-degree-of-freedom module (2200) to move to the specified position based on the size and position information of the pillow spring and the bevel wedge, and rotates the F-shaped support plate (2101) of the bevel wedge bearing fixture (2100) counterclockwise by 90° to make it horizontal; then, the industrial robot (1300) moves to the specified position according to the motion instructions of the controller, controls the current on and off of the coil of the disassembly and assembly fixture (1100) and the action of the cylinder, and places the left-side bevel wedge from the preparation area to the F-shaped support plate (2101); then, the host computer drives the three-degree-of-freedom module (2200) based on the size and position information of the bevel wedge. The group (2200) and its load end move the inclined wedge to the inside of the bolster and the side frame and lift it up to a certain height, and then rotate the F-shaped support plate (2101) of the inclined wedge bearing tooling (2100) clockwise by 90°; at the same time, the industrial robot (1300) moves to the specified position according to the motion command of the controller, controls the current on and off of the coil of the disassembly and assembly fixture (1100) and the cylinder action, takes out the second row of left-side bolster springs from the preparation area and places them at the specified position on the left side of the side frame; finally, the host computer and the industrial robot (1300) controller drive the three-degree-of-freedom module (2200) and the auxiliary inclined wedge disassembly and assembly unit (2) to move to the specified position; T34. Install the right-side wedge and pillow spring of the second row: refer to the installation steps of the left-side wedge and pillow spring to install the right-side wedge and pillow spring; T35. Install the middle pillow spring of the second row: the industrial robot (1300) moves to the designated position according to the motion instruction of the controller, controls the current on and off of the coil of the disassembly and assembly fixture (1100) and the action of the cylinder, takes out the middle pillow spring of the second row from the preparation area and places it at the designated position in the side frame; after completing the installation of the middle pillow spring of the second row, the mechanical arm of the industrial robot (1300) returns to the designated position; T4, first row of pillow spring installation T41. The end of the industrial robot (1300) moves to the front end of the pillow spring in the material preparation area, and the machine vision sensor (1200) scans the size and position information of the pillow spring, identifies the size and position information of the pillow spring by analyzing the point cloud data, and transmits the information to the host computer; T42, the host computer processes the acquired component size and position information, and sends the size and position information of the pillow spring to the industrial robot (1300) controller through the network port; the industrial robot (1300) controller assigns and calculates the motion instructions and parameters according to the acquired pillow spring size and position information, and appropriately adjusts and optimizes the spatial point coordinate values ​​and motion instruction parameters of the default path to meet the installation operation of the first row of pillow springs; T43. Installing the first row of pillow springs: the industrial robot (1300) moves to the designated position according to the motion command of the controller, controls the current on and off of the coil of the disassembly and assembly fixture (1100) and the movement of the cylinder, and takes out the first row of pillow springs from the preparation area in sequence and places them at the designated position in the side frame; after completing the installation of the first row of pillow springs, the industrial robot (1300) mechanical arm returns to the designated position; T5, bogie rotation action: the industrial robot (1300) and the three-degree-of-freedom module (2200) return to their initial positions, and the rotating mechanism of the hoisting line drives the bogie to rotate 180°; T6, loop operation: repeat steps T1-T4.
