Description

Technical Field

[0001] The present invention mainly relates to the technical field of teaching platforms, and specifically to a smart teaching platform and an application method thereof. Background Art

[0002] With the development of science and technology, teaching is becoming more and more advanced. Various intelligent teaching devices have emerged to replace the traditional teaching method of teachers writing on the blackboard. For example, the projection method requires teachers to prepare PPT in advance and then project and explain it. However, making PPT also consumes a lot of teachers' time and energy. There are also some devices in the existing technology that can collect content from books and directly project them on the screen, but these devices have certain defects.

[0003] This type of device can only collect data on the two sides of the book that are currently unfolded. If it is facing the entire book, it cannot automatically turn the pages when collecting content. The teacher can only turn on the device after collecting one page, turn the page, and then collect again. In addition, when explaining, if you want to turn the page back, it cannot be done and needs to be turned manually. Summary of the invention

[0047] The working principle of the present invention is as follows: unfold the book 120 to the page that needs to be explained, place the book 120 on the display stand 104, with the spine located on the vertical groove of the display stand 104, pull the transparent pressing blocks 135 on both sides to clamp the two sides of the book 120, and then operate on the display touch screen 101. At this time, it is necessary to scan and start the scanning motor 105 to drive the scanning shaft 122 to rotate, and the scanning shaft 122 drives the scanning rod 121 to rotate, and use multiple cameras 153 to capture the content of the page to the display screen for projection. When the current page is captured, it is necessary to turn the page, that is, the page on the right side of the book 120 needs to be turned to the left.

[0048] At this time, click the page turning function on the display touch screen 101, choose to turn from the right to the left, start the moving motor 107 to drive the main lower connecting rod 108 to rotate, the main lower connecting rod 108 drives the horizontal rod 109 and the main upper connecting rod 110 to rotate, and under the action of the auxiliary lower connecting rod 106 and the auxiliary upper connecting rod 113, the moving frame 112 is finally pushed to slide in the arc-shaped slide groove 111, and the moving platform 114 is moved to the right, and the moving motor 107 is stopped; then the inner adjustment motor 107 is started again. 17 drives the first inner adjustment rod 115 and the second inner adjustment rod 119 to rotate, so that the front end plate clamping shaft 128 on the right side of the page turning front end plate 118 is clamped into the clamping arc groove 125 on the right side of the moving platform 114, and the rubber wheel 154 on the left side of the page turning front end plate 118 contacts the page of the book 120, stops the inner adjustment motor 117, starts the clamping cylinder 123 to drive the clamping long shaft 126 to slide, so that the clamping frame 124 on the right side of the clamping long shaft 126 clamps the front end plate clamping shaft 128, as shown in FIG. Figure 3 shown.

[0049] After being ready, the lifting motor 144 is started to drive the threaded rod 143 to rotate, so that the threaded slider 146 slides. The threaded slider 146 is sliding up at this time, and when sliding up, it drives the lifting gear 142 to rotate counterclockwise, and then drives the slip ring rack 139 to descend. The slip ring rack 139 descends with the long slip ring 140, and the bending rod 138 tilts one end and pulls the transparent pressure block 135 at the other end to loosen the fixation of the page of the book 120. At the same time, the page turning motor 133 is started to drive the page turning pinion 132 to rotate, and the friction rotating rod 129 is driven to rotate under the action of the page turning pulley 130 and the page turning transmission belt 131. The rubber wheel 154 is used to push up the paper, and then during the continuous rotation of the friction rotating rod 129, the cross bar at the other end of the friction rotating rod 129 will be inserted between the rolled page and the page below, that is, the cross bar passes over the current page and reaches the bottom of the current page. At this time, the paper is located above the friction rotating rod 129.

[0050] Then stop the friction rod 129, start the moving motor 107 to reverse, drive the moving frame 112, the moving platform 114, and the page turning front end plate 118 to move from the right side to the left side, and the friction rod 129 will carry the page from the right side to the left side to realize page turning. When the page is turned over, the transparent pressure block 135 on the left side opens and presses the page coming over, and start the lifting motor 144 to reverse, so that the threaded slider 146 descends. The threaded slider 146 descends to press the combined special-shaped ring 148 to descend, and the combined special-shaped ring 148 drives one end of the angle connecting rod 147 to tilt, and the other end pulls the transparent pressure block 135 to loosen the fixation on the book 120.

[0051] When the page is turned over, the lifting motor 144 is started to drive the threaded slider 146 to rise, thereby closing the transparent pressing block 135, and the transparent pressing block 135 clamps and fixes the page to realize the page turning operation; after turning the page, the scanning rod 121 is used to scan and project; if it is necessary to explain the content back, that is, turn the page from the left to the right, the above operation can be achieved by performing it in reverse.

[0052] Embodiment 2: A method for applying a smart teaching platform, using the above-mentioned smart teaching platform, comprises the following steps:

[0053] Step 1: unfold the book 120 and place it on the display stand 104, manually pull the transparent pressing blocks 135 on both sides, and use the transparent pressing blocks 135 to press both sides of the book 120, so that the current page can be scanned and projected;

[0054] Step 2: When it is necessary to turn the page, operate on the display touch screen 101 to start the moving motor 107 to drive the moving frame 112 to slide on the large support 102, so that the moving platform 114 and the page turning front end plate 118 arrive at one side of the bending rod 138 on the large support 102; adjust the overall direction of the page turning;

[0055] Step 3: Start the inner adjustment motor 117 to drive the page turning front end plate 118 to rotate, so that the front end plate clamping shaft 128 on the page turning front end plate 118 away from the page turning motor 133 contacts the clamping arc groove 125 on the right side of the moving platform 114, and then start the clamping cylinder 123 to drive the clamping frame 124 on the right side to clamp the front end plate clamping shaft 128, and adjust the angle of the page turning front end plate 118, so that the rubber wheel 154 on the left side of the page turning front end plate 118 contacts the book 120; adjust the angle and orientation of the page turning front end plate 118 to make page turning smoother;

[0056] Step 4: Start the threaded assembly to drive the threaded slider 146 to slide upward, so that the bending rod 138 descends, and the bending rod 138 drives the pressure plate on the side of the bending rod 138 to release the pressure on the book 120; the pressure on the page is released in advance, so that the page can be rolled up;

[0057] Step 5: Start the page turning motor 133, and drive the friction rotating rod 129 to rotate under the action of the belt assembly, so that the rubber wheel 154 rolls up the page on the book 120, and the other end of the friction rotating rod 129 is inserted into the page, and the page turning motor 133 is stopped, and the moving motor 107 is started to move the moving platform 114 and the page turning front end plate 118, and the page of the book 120 is turned to the left; the automatic page turning operation is realized as a whole;

[0058] Step six, at the same time as step five, use the threaded assembly to drive the threaded slider 146 to descend, so that the angle link 147 descends, and open the pressure plate on the side of the angle link 147. When the page is turned over, the pressure plate will press the page again. When the page is turned over, the pressure plate will be opened at the same time to leave space to receive the page, and the page will be pressed immediately after it comes over.

[0059] Any matters not described in the present invention are applicable to the prior art.
