Description

Technical Field

[0001] This utility model relates to the technical field of robotic grinding workstations, specifically an automatic sandpaper changing device. Background Technology

[0002] In the field of robotic automated sanding and polishing, sandpaper, as a consumable, needs frequent replacement. Traditional manual sandpaper replacement methods have several drawbacks: firstly, manual replacement makes it difficult to ensure consistency each time, potentially affecting sanding quality; secondly, operators are exposed to harsh environments such as dust and noise for extended periods, threatening their health; furthermore, manual replacement is inefficient, increasing labor costs and failing to meet the demands of large-scale automated production. While some existing sandpaper replacement devices exist, most are complex in structure, poorly adaptable, and cannot simultaneously handle the automatic replacement of both round and square sandpaper sheets. Furthermore, the collection of waste sandpaper and the adhesion of new sandpaper are not stable enough, affecting the sanding cycle time. Therefore, there is an urgent need for a sandpaper replacement device that is simple in structure, highly adaptable, and capable of fully automated, unmanned operation. Utility Model Content

[0018] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0019] refer to Figure 1 and Figure 2This utility model discloses an automatic sandpaper replacement device, comprising a sandpaper storage bin 1, a waste sandpaper detachment module 2, a waste sandpaper collection cylinder 3, and a cabinet 4; the sandpaper storage bin 1 is installed on the cabinet 4 for storing sandpaper; the waste sandpaper detachment module 2 is installed on the cabinet 4 for separating waste sandpaper from the adhesive tray; a waste sandpaper collection cylinder 3 is provided on one side of the cabinet 4 below the waste sandpaper collection cylinder 3 for collecting detached waste sandpaper.

[0020] The sandpaper storage chamber 1 in this embodiment includes a pressure plate 1-1, a tray 1-2, an optical axis 1-3, a base plate 1-4, a tray guide shaft 1-5, a buffer pad 1-6, a linear bearing 1-7, a cylinder 1-8, and a pressure plate guide shaft 1-9.

[0021] The base plate 1-4 is fixedly installed in a designated position inside the cabinet 4 by bolts; a tray 1-2 is set above the base plate 1-4; a cylinder 1-8 is fixed to the base plate 1-4 by a cylinder mounting seat, and the piston rod of the cylinder is connected to the tray 1-2 by a nut; a tray guide shaft 1-5 is fixed to the back of the tray 1-2 by screws; a linear bearing 1-7 is installed on the base plate 1-4; the tray guide shaft 1-5 moves along the linear bearing 1-7, and the cylinder 1-8 drives the tray 1-2 to move up and down linearly under the action of the tray guide shaft 1-5; a pressure plate 1-1 is located above the tray 1-2, and sandpaper is located between the tray 1-2 and the pressure plate 1-1; a pressure plate guide shaft 1-9 is fixed to the back of the pressure plate 1-1 by screws; the pressure plate guide shaft 1-9 moves along the linear bearing 1-7.

[0022] An optical axis 1-3 and a buffer pad 1-6 are also mounted on the base plate 1-4. The buffer pad is used to buffer the movement of the pressure plate 1-1. The pressure plate in this embodiment includes a pair of arc-shaped plates, and arc-shaped slots matching the optical axis are provided on the inner side of the arc-shaped plates.

[0023] Multiple sandpaper storage compartments 1 are set on cabinet 4.

[0024] The waste sandpaper shedding module 2 includes an adjustment limit plate 2-1, a base plate 2-2, a vertical plate 2-3, and a sandpaper tearing board 2-4;

[0025] The base plate 2-2 is installed on the cabinet 4; an adjustment limit plate 2-1 is set above the base plate 2-2; the adjustment limit plate 2-1 is installed on the base plate 2-2 around the perimeter via vertical plates 2-3; a sandpaper drop opening is provided on the adjustment limit plate 2-1; a sandpaper tearing board 2-4 is set above the sandpaper drop opening; a shim is set between the sandpaper tearing board 2-4 and the adjustment limit plate 2-1, so that there is a height difference between the sandpaper tearing board 2-4 and the adjustment limit plate 2-1.

[0026] The waste sandpaper collection bin is an external structure, making it easy to remove and replace.

[0027] Cabinet 4 is equipped with a unified input / output interface 5 for interacting with the robot.

[0028] Working principle: When new sandpaper needs to be replaced, the robot moves the dip plate to the sandpaper storage compartment 1. Cylinder 1-8 is activated, causing tray 1-2 to move under the action of tray guide shaft 1-5, delivering the sandpaper on tray 1-2 to the designated position. Pressure plate 1-1, guided by pressure plate guide shaft 1-9, flattens the curled sandpaper. The cylinder continues to drive tray 1-2, ensuring the sandpaper makes full contact with and adheres to the dip plate.

[0029] When it is necessary to replace the waste sandpaper, the robot moves the dip plate to the waste sandpaper removal module 2. The dip plate slides on the sandpaper tearing board 2-4. Due to the height difference between the sandpaper tearing board 2-4 and the limiting plate 2-1, the sandpaper tearing board 2-4 is inserted between the sandpaper and the dip plate, tearing off the waste sandpaper. The waste sandpaper falls into the waste sandpaper collection cylinder 3.

[0030] Throughout the entire operation, the unified input / output interface 5 enables signal and power interaction between the device and the robot, ensuring precise motion control. The external waste sandpaper collection tube 3 can be easily removed for cleaning or replacement without affecting the normal operation of the device.
