Description

Technical Field

[0001] This invention relates to the field of mobile platform technology, and more particularly to a precisely positionable cross-slot gantry mobile platform. Background Technology

[0002] Single-slot truss mobile platforms are commonly found in automated surface treatment production lines such as electroplating, anodizing, pickling, coating, or cleaning. They are automatic actuators that stand above a single process tank, use a truss structure as their travel track, and can reciprocate along the length of the tank. They are often used to carry workpiece booms, spraying devices, agitators, or inspection probes.

[0003] In electroplating production lines, existing mobile platforms often lack effective positioning measures, which can cause the lifting mechanism on the mobile platform to be unable to accurately lift and lower the stainless steel plates in the electrolytic cell, resulting in the stainless steel plates falling off the lifting mechanism or failing to effectively fix the stainless steel plates on the lifting mechanism.

[0018] Figure 9 for Figure 1 A magnified view of a portion of the image. Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] The present invention discloses a cross-slot gantry mobile platform that can be precisely positioned, which is mainly applied to scenarios where existing mobile platforms often lack effective positioning measures.

[0021] Reference Figures 1-9 A precisely positioned cross-slot truss mobile platform includes a road panel 1, which is matrix-planned with multiple square working areas 11. Each square working area 11 includes a buffer working area 111 and an electrolytic cell working area 112. The road panel 1 is provided with first road guide rails 12 on its front and rear edges, and second road guide rails 13 are provided on the left and right sides of each square working area. The first road guide rails 12 and the second road guide rails 13 are vertically connected. It includes several side transfer carts 14, which are used to carry the anode sheet extraction device 15 to move in the left and right direction on the first road guide rail 12. When the side transfer cart 14 is aligned with one of the square working areas 11, the anode sheet extraction device 15 docks with the corresponding second road guide rail 13 to enter the corresponding square working area 11 or moves away from the square working area 11 from the second road guide rail 13 to enter the side transfer cart 14. The anode sheet extraction device 15 is provided with a lifting mechanism 4. The lifting mechanism 4 is used to grab and lift the anode copper plate 10 in the working area 112 of the electrolytic cell.

[0022] In this embodiment, by setting up the second road surface guide rail 13 and the first road surface guide rail 12, and simultaneously setting up the side transfer trolley, it can move left and right on the first road surface guide rail 12 and move back and forth on the second road surface guide rail 13, thereby driving the corresponding anode sheet extraction device 15 to each electrolytic cell working area 112. This changes the traditional requirement of having multiple anode sheet extraction devices corresponding to each row of electrolytic cells working areas, thereby reducing the number of anode sheet extraction devices and enabling the anode sheet extraction device to move to any electrolytic cell to work.

[0023] Furthermore, a positioning and anti-deviation module 8 is provided on the outside of the lifting mechanism 4, and a locking module 9 is provided on the outside of the anode sheet extraction device 3.

A three-dimensional vision camera 813 is bolted to the bottom of the lifting mechanism 4.

[0024] Specifically, the device utilizes the positioning anti-deviation module 8 to enable rapid positioning of the electrolytic cell working area 112 and the stainless steel plate 6 during operation, thereby improving the smoothness of the device's operation and significantly reducing the impact of device deviation on positioning capability. This allows the lifting mechanism 4 to accurately grasp the stainless steel plate 6, greatly improving the device's operating efficiency and positioning capability.

A fixing ring 807 is bolted to the end of the coil spring 806 away from the arc-shaped contact arm 801. The fixing ring 807 is bolted to the opposite side of the outside of the rectangular block 804 on the same side. The bottom of the lifting mechanism 4 is bolted to two symmetrical hydraulic rods 811. The output ends of the two hydraulic rods 811 are bolted to the outside of the mounting base 802. Connection; Two symmetrical sliding grooves are provided on the side of the mounting base 802 away from the hydraulic rod 811. Limiting rods 810 are slidably connected within each groove. The upper side of the limiting rods 810 is bolted to the bottom of the lifting plate mechanism 4. Multiple symmetrical laser rangefinders 12 are installed on the anode sheet extraction device 3. Multiple symmetrical protrusions are bolted to the outside of the electrolytic cell working area 112. Positioning elements 11 are installed on each protrusion. The positioning elements 11 and the laser rangefinders 12 on the same side are located on the same plane. Two symmetrical hydraulic rods 812 are bolted to the outside of the mounting base 802. The output ends of the two hydraulic rods 812 are bolted to the outside of the rectangular block 804 on the same side. The electrode extraction device 3 has two symmetrical extension plates 13 bolted to its exterior. The upper sides of each extension plate 13 are bolted to the bottom of a V-shaped groove 816 on the same side. The V-shaped groove 816 has multiple symmetrical inclined grooves 820 on its exterior. Each V-shaped groove 816 has a cutting groove on its upper side, and each cutting groove contains an oil delivery pipe 821. Multiple equally spaced nozzles 822 are installed outside the oil delivery pipes 821, and the nozzles 822 on the same side are surrounded by a common sealing plate 823. The exterior of the sealing plate 823 is bolted to the inner wall of the cutting groove. The upper sides of each extension plate 13 have two symmetrical uprights bolted to their exteriors.

One end of the threaded rod 818 is bolted to the outside of the extrusion block 817 on the same side, and a double nut 819 is installed on the outside of the threaded rod 818.Both fixed plates 814 have circular holes, and each hole contains a lead screw 815. The upper sides of both extension plates 13 are bolted to two symmetrical bosses, each boss having a circular opening. The inner wall of each opening is rotatably connected to the outer side of the lead screw 815 on the same side via bearings. Furthermore, the upper sides of both extension plates 13 are bolted to a rotary motor 14, the output end of which is connected to one end of the lead screw 815 on the same side via a coupling.

[0026] In specific application scenarios, the positioning anti-deviation module 8 is mainly used in the positioning anti-deviation stage of the positioning anti-deviation process. That is, the positioning anti-deviation module 8 can significantly improve the smoothness of the movement of the lifting mechanism 4 on the moving platform 3 by using the V-shaped slide 816, the fixed plate 814, the inclined groove 820, the oil pipe 821, and the nozzle 822, and significantly reduce the friction and vibration of the lifting mechanism 4 on the moving platform 3 during operation, thereby greatly reducing the movement deviation of the lifting mechanism 4 during operation. By using the stacked rotating motor 14 and the lead screw 815, the transmission gap can be eliminated, preventing the crossbeam from tilting due to the cumulative error on both sides, and ensuring the repeatability of positioning accuracy in the dedicated running direction. With the help of the three-dimensional vision camera 813, the arc-shaped contact arm 801, the contact sensor 809, the coil spring 806, and the angle sensor 805, the relative position of the stainless steel plate 6 and the lifting mechanism 4 can be precisely controlled, thereby completing the alignment of the lifting mechanism 4 and the stainless steel plate 6, significantly increasing the gripping accuracy of the lifting mechanism 4 and reducing errors.

[0027] Reference Figure 7 and Figure 8 In a preferred embodiment, the locking module 9 includes an outer frame 901, which is disposed outside one of the extension plates 13. The outer frame 901 is bolted to the upper side of the lifting mechanism 4, and a controller 902 is bolted to the outer frame 901. Two symmetrical small holes are formed on the bottom inner wall of the outer frame 901, and a movable frame 905 is slidably connected to the two holes. A friction plate 904 is bolted to the upper side of the movable frame 905, and a friction pad 905 is bolted to the bottom of the extension plate 13 on the same side as the movable frame 905. 03. The upper side of the friction plate 904 is attached to the bottom of the friction piece 903; the bottom of the outer frame 901 is connected to the magnetic shielding coating 910 by bolts, the bottom of the magnetic shielding coating 910 is connected to the electromagnet 907 by bolts, and the bottom of the movable frame 905 is connected to the connecting plate 908 by bolts, the upper side of the connecting plate 908 is connected to the magnet piece 909 by bolts, the upper side of the magnet piece 909 is attached to the bottom of the electromagnet 907; the inner wall of the bottom of the outer frame 901 is connected to the spring 906 by bolts, and the other end of the spring 906 is connected to the outside of the movable frame 905 by bolts.

[0028] In specific application scenarios, the locking module 9 is mainly used in the locking process. That is, the locking module 9 uses electromagnet 907, magnet 909, movable frame 905, friction plate 903 and friction plate 904 to move the lifting mechanism 4 to the target position for grasping, and locks the position of the lifting mechanism 4. The holding torque of the rotating motor 14 is converted into mechanical hard locking, eliminating the slight drift caused by power failure or external disturbance, and reducing the impact of the slight error caused by drift on the positioning capability of the device.

[0029] Working principle: When the lifting mechanism 4 needs to grab the stainless steel plate 6 in the electrolytic cell working area 112, the moving platform 3 will move towards the electrolytic cell working area 112 on the second road guide rail 13. When the laser emitted by the laser rangefinder 12 on the moving platform 3 first contacts the positioning component 11 on the electrolytic cell working area 112, the moving platform 3 will decelerate, thereby accurately aligning the laser rangefinder 12 on the moving platform 3 with the positioning component 11, completing the synchronization of the position of the moving platform 3 and the electrolytic cell working area 112. The rotating motor 14 is then started, which drives the lead screw 815 to rotate, causing the fixed plate 814 to slide on the V-shaped slide groove 816, thus moving the lifting mechanism 4 towards the stainless steel plate 6 to be grabbed. After the contact sensor 809 on the arc-shaped contact arm 801 moves to contact one side of the stainless steel plate 6, the rotating motor 14 decelerates. Under the influence of torque, the arc-shaped contact arm 801 rotates against the torque of the coil spring 806. The angle sensor 805 records the rotation angle of the arc-shaped contact arm 801. After reaching the preset value, the lifting mechanism 4 and the stainless steel plate 6 to be grasped are on the same plane. The lifting mechanism 4 is activated to grasp the stainless steel plate 6. When it is necessary to go around multiple stainless steel plates 6 to grasp the stainless steel plate 6 behind, the three-dimensional vision camera 813 is activated to observe the position of the stainless steel plate 6 to be grasped. The hydraulic rods 1 and 2 are activated to retract the mounting base 802 and the rectangular block 804 upwards, thereby making the arc-shaped contact arm 801 rotate. The reach arm 801 can pass over the stainless steel plate 6 that does not need to be grasped. Before reaching the position of the stainless steel plate 6 that needs to be grasped, it unfolds again. After the fixed plate 814 moves from one end of the moving platform 3 to the other, the squeezing block 817 squeezes the airbag 824, thereby delivering the air in the airbag 824 to the upper part of the oil tank 827, increasing the air pressure in the oil tank 827, pumping the lubricating oil in the oil tank 827 into the oil delivery pipe 821 and discharging it through the nozzle 822. The lubricating oil is distributed along the inclined groove 820 to the surface of the V-shaped slide groove 816. During the movement of the fixed plate 814, the lubricating oil is evenly coated through the contact surface between the V-shaped slide groove 816 and the fixed plate 814. When the lifting mechanism 4 moves to the stainless steel plate that needs to be grasped... After the plate 6 is aligned above the ground, the controller 902 de-energizes the electromagnet 907, thus eliminating the repulsive force generated by the electromagnet 907. Under the pull of the spring 906, the movable frame 905 moves upward, tightly adhering the friction plate 904 to the friction pad 903, locking the position of the lifting mechanism 4 and the moving platform 3. At this time, the controller 902 de-energizes the rotary motor 14. After the lifting mechanism 4 completes the gripping of the stainless steel plate 6, the controller 902 energizes the electromagnet 907 again, causing the electromagnet 907 to repel the magnet 909 downward, driving the movable frame 905 to move downward against the elastic force of the spring 906, contacting the friction pad 903 and adhering to the friction plate 904. The rotary motor 14 is energized again, driving the lifting mechanism 4 to move.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
