Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0074] The placement platform 21 is installed on the conveying mechanism and has a mounting port 210 coaxially arranged.

[0075] A rotating platform 22 is rotatably mounted at the mounting port 210;

[0076] The rotary table 22 is radially slidably connected with a plurality of limiting shafts 23, and a storage area for placing the display screen is formed between the limiting shafts.

[0077] When the limiting shaft 23 slides radially, the size of the storage area can be adjusted.

[0078] In this embodiment: the rotary table 22 includes:

[0079] A rotating body 220 is provided at the mounting port 210, and a limiting slider 221 is provided on the circumferential side wall, and a groove 210a for the limiting slider 221 to slide is provided on the inner wall of the mounting port 210.

[0080] A radial groove 222 is provided on the rotating body 220 and extends radially;

[0081] The limiting shaft 23 is slidably disposed in the radial slide groove 222, and a driving part 23a is formed at one end. A limiting spring 225 connecting the limiting shaft 23 and the radial slide groove 222 is installed in the radial slide groove 222.

[0088] In this embodiment, depending on the size of the display screen, the first PLC motor controls the rotation of each pulley and drives each drive wheel to rotate. This causes the different protrusions on the drive wheels to contact the drive part of the limiting shaft, thereby driving the limiting shaft to move. This adjusts the distance between the limiting shaft and the center of the rotating body, thereby reducing or expanding the storage area and thus fixing display screens of different sizes.

[0089] Example 2 differs from Example 1 in that, as Figure 4 As shown, the top of the rotating body is provided with a drive groove 31:

[0104] In this embodiment: the vacuum cleaner 60 includes:

[0105] The main body has a dust suction chamber 63;

[0106] Mounting slots 70 are formed on both sides of the body;

[0107] A connecting cavity 71 is located within the main body and is connected between the dust suction cavity 63 and the mounting groove 70;

[0108] The suction part 72 is slidably disposed in the mounting groove 70, and a return spring 73 connected to the suction part 72 is provided in the mounting groove 70. In this embodiment, the suction part 72 is provided with a first sealing block 72a and a second sealing block 72b. The second sealing block 72b is provided with a through opening 72c. The edge of the suction part 72 is provided with a third sealing block 72d that can close the mounting groove 70. When the suction part 72 is reset by the return spring 73, the third sealing block 72d is in contact with the outer wall of the body, and only the reserved gaps in the mounting groove are used for airflow to enter.

[0109] A dust inlet chamber 74 is formed inside the dust suction section 72, and a dust suction hole 74a connected to the dust inlet chamber 74 is provided at the bottom of the dust suction section 72;

[0110] The sliding rod 75 is connected to the vacuuming part 72 and is movably disposed in the connecting cavity 71;

[0111] An electromagnet 76 is provided inside the main body, and a magnet 76a with opposite magnetic poles to the electromagnet 76 is provided on the dust suction part 72;

[0112] The sliding rod 75 is provided with a chamber 75a that connects the dust suction chamber 63 and the dust inlet chamber 74.

[0113] In this embodiment: the sliding rod 75 includes:

[0114] The rod is mounted on the suction unit 72 and is movable within the connecting cavity 71, and has the cavity 75a;

[0115] The sealing part 75b is installed at one end of the rod body near the suction chamber 63;

[0116] A connection port 75c is formed on the outer wall of the rod and communicates with the connection cavity 71 and the chamber 75a;

[0117] The diameter of the connecting cavity 71 gradually decreases from the direction of airflow.

[0118] In this embodiment: a cleaning chamber 80 is provided on the wall of the mounting groove 70. The cleaning chamber 80 extends into the body and communicates with the dust suction chamber 63. The air inlet of the cleaning chamber 80 is located between the first sealing block 72a and the third sealing block 72d.

[0119] refer to Figures 4-7 The principle of this embodiment is as follows:

[0120] During dust removal, the clamp holding the display screen can be placed on the drive disk, which has a drive groove adapted to the drive disk, such as the clamping mechanism of Embodiment 1.

[0121] Taking the clamping mechanism of Embodiment 1 as an example, during dust removal, the conveying mechanism controls the clamping mechanism to enter the dust removal chamber, the first lifter controls the rotating shaft to rise, and makes the drive disk on the rotating shaft cooperate with the drive groove at the bottom of the rotating table of the clamping mechanism. Therefore, when the rotating shaft rotates, it can drive the rotating table to rotate, thereby driving the display screen to rotate.

[0122] As the display screen rotates, the second lifter controls the suction unit to descend and approach the display screen. Then, the electromagnet is energized and drives the suction unit out of the mounting slot via a magnet (at this time, the first and second sealing blocks seal the gap between the suction unit and the mounting slot, and the first sealing block can also seal the air inlet of the cleaning chamber), so that the suction hole is exposed in the mounting slot. When the vacuuming device is started, dust enters through the suction hole and passes through the dust inlet chamber, the chamber, the connecting chamber, and the suction chamber in sequence, finally completing the vacuuming work. The rotating display screen can improve the suction effect of the suction unit on the display screen and reduce the vacuuming dead corners.

[0123] It is worth mentioning that:

[0124] The suction unit in this embodiment also has a self-cleaning function. That is, when the electromagnet is de-energized, the suction unit is reset by the reset spring, thereby sealing the gap between the mounting groove and the suction unit through the third sealing block, while leaving the gap above the mounting groove intact. Therefore, when the suction device is started, the gas enters from the gap above the mounting groove and enters the mounting groove through the opening provided on the second sealing block, then enters the chamber through the connection port, passes through the dust inlet chamber, and is discharged through the suction hole into the cleaning chamber, and is finally discharged. Therefore, this embodiment can clean the suction hole through the above cleaning, thereby avoiding the clogging of the suction hole due to long-term use.

[0125] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
