Description

Smart multifunctional whiteboard cleaning assistant equipment

The present invention relates to an intelligent multifunctional whiteboard cleaning assistant device, especially a function setting that can switch between large and small wiping rollers and control the movement of the stroke, and can determine whether to activate a large-area wiping roller or a small-area wiping roller according to the wiping area. Whiteboard auto-wipe technology for wiping whiteboards.

Press, the blackboard or whiteboard is the writing board used by various academic institutions for teaching purposes at present, so in addition to writing, teachers must also wipe off the teaching information written on the blackboard or whiteboard, so as to ensure enough to express the teaching Information writing area. Furthermore, in the usual class, every time a teacher writes on the blackboard or whiteboard, he has to wipe the blackboard or whiteboard, which not only wastes precious time in class, but also causes chalk dust to float everywhere. This problem seriously affects the teaching and learning quality of teachers and students. In order to change the aforementioned deficiencies, the relevant technical field has developed the following patent cases for automatic blackboard erasing machines:

1. The Invention Bulletin No. I329077 "Automatic Blackboard Erasing Machine" includes a gear set, which is arranged on the left and right ends of the top side of the writing board for driving and sliding to the board surface area to be wiped, And between the left and right ends of the writing board, there is a slide rail for sliding to the board surface blocks; a belt is set on the gear set on the left and right ends of the top side of the writing board to match the gear set act as a drive and perform a displacement action on the slide rail; a plurality of position sensors are arranged on the slide rail and electrically connected to the boundary of the board surface block to sense whether the trigger is received or not. board block The position at the boundary triggers a signal and feeds back the signal to a single chip to control whether the motor is driven or not; a moving slider is assembled on the slide rail between the belt and the gear set; a telescopic neck, the top of which is It is pivotally connected to the bottom end of the moving slider, and has two-stage telescopic parts, respectively a first telescopic part and a second telescopic part, which are used to make the plate surface block from the bottom end of the moving slider. vertical extension; a wiping member pivotally connected to the second telescopic portion of the telescopic neck, and properly abutting on the board surface of the writing board for erasing the handwriting on the board surface block; a The dust collecting part is pivotally connected around the wiping part, and is used for absorbing the dust that has been wiped off; when reaching the area of the board surface to be wiped, the wiping part can be driven by the retractable neck to wipe the writing board The writing on it, and the dust suction is performed by the vacuuming component synchronously. Although the patent has the functions of block division and small area wiping, but the structure of the wiping part driven by the retractable neck does not effectively complete the wiping part during the wiping process due to the length of the retractable neck being stretched too long. The lack of sticking to the blackboard occurs, resulting in unstable wiping, which results in poor wiping effect of the blackboard.

2. New Announcement No. M500690 "Orbital Telescopic Automatic Plate Eraser", which includes a rail, which is arranged on the upper end of the blackboard; There is a wiper at the end of the rod, so that the telescopic rod can move left and right on the track, and can be extended and retracted upwards and downwards, so that the wiper at the end of the rod can be driven by the driving device. It can move up, down, left and right on the surface of the blackboard to wipe all corners of the entire blackboard; and at least one eraser, which is installed under the two sides of the blackboard; The drive of the device enables the eraser to wipe all corners of the entire blackboard. At the same time, the eraser can also be moved to the top of the eraser, and the eraser can be lifted to make the wiping surface of the eraser contact the eraser, and the negative pressure suction of the eraser can be used to absorb the eraser. Wipe the chalk dust off the face. Although the patent has a block Divide and block small-area wiping function; however, the structure of the board wiper driven by the telescopic rod will indeed cause the board wiper to be unable to be effectively attached to the blackboard due to the extension of the extended rod during the wiping process. Unstable incidents occur, resulting in incidents that cause the blackboard cleaning effect to be poor.

3. New Announcement No. M555296 "Automatic Blackboard Vacuuming System", which includes a camera unit, which is used to shoot the actual use of the blackboard at an appropriate shooting angle, and sends out continuous images corresponding to the actual use of the blackboard; an image recognition unit, It is electrically connected with the photographing unit to receive the continuous image, and when the image of the blackboard wiping action appears in the continuous image, a vacuuming signal is sent; a plurality of blackboard vacuuming units are arranged at appropriate positions relative to the blackboard , which is electrically connected to the image recognition unit for receiving the cleaning signal, and when receiving the cleaning signal, starts cleaning the blackboard for a preset time; although this patent has an image recognition blackboard with a blackboard-wiping action Wipe function; however, the image recognition technology has to spend more system processing resources and computing time and other costs, resulting in the delay of the blackboard wiping.

The intelligent multifunctional whiteboard cleaning assistant device as claimed in claim 3, wherein the two sets of vertical plates are pivotally pivoted with the two side plates of the machine base at the bottom near the middle section respectively; A fixed rod near the top between the assembly plates and a linear actuating group set on the machine base, the linear actuating group has an actuating rod with multi-stage telescopic actuating functions, and the end of the actuating rod abuts against the fixed rod. In the middle position, when the actuating lever is in the retracted position, the two sets of vertical plates rotate clockwise with the pivoting position as the pivot point, so that the main wiping roller abuts against the whiteboard; when the actuating lever is in the middle position , the two sets of vertical plates rotate counterclockwise with the pivot position as the pivot point, so that neither the main wiping roller nor the auxiliary wiping roller can interfere with the whiteboard; when the actuating lever is in the extended position, the two The assembly plate rotates counterclockwise with the pivot position as the pivot point, so that the pair of wiping rollers abuts against the whiteboard. The intelligent multifunctional whiteboard cleaning assistant device as claimed in claim 1, wherein the signal processing module divides the whiteboard into a plurality of wiping blocks, and sets each wiping block to include a set of moving stroke control parameters and An action control parameter, each group of movement control parameters and the action control parameter corresponds to a wipe command. When the manipulation module generates a wipe command, after being interpreted by the signal processing module, a wipe command corresponding to the set is generated. Movement stroke control parameters and the The motion control parameter corresponds to a movement stroke control parameter and an action control parameter, and the linear drive unit, the rotation drive mechanism and the switching drive mechanism are driven and controlled by the control command. The intelligent multifunctional whiteboard cleaning assistant device as claimed in claim 1, further comprising an image capture device, the image capture device is used for continuously capturing the writing images of the whiteboard to form a writing image, and passing the short distance The wireless communication system is transmitted to the smart phone; the wiping control interface display further includes an image overlay input interface, when the user touches the image overlay input interface, the writing image is overlaid on the rectangular frame input interface, To assist the user to select and click the block to be wiped and removed.
