As shown in fig. 1-4, embodiments of the present disclosure provide a glass panel washer comprising: a turntable mechanism, comprising: the device comprises a bracket 1, a lower turntable 2, an upper turntable 3 and a turntable motor 8; wherein, the lower turntable 2 and the upper turntable 3 are oppositely arranged along the up-down direction and are rotatably arranged on the bracket 1; a rotary mounting position for mounting and rotating the glass panel 24 is formed between the lower turntable 2 and the upper turntable 3, and a plurality of rotary mounting positions are circumferentially arranged; at least one of the lower turntable 2 and the upper turntable 3 is in driving connection with a turntable motor 8; and a cleaning mechanism for cleaning each glass panel 24 rotated to its station by the turntable mechanism, and comprising: a brushroll 18 and a brushroll motor 22; the brush roller 18 is used for cleaning the glass panel 24, and the brush roller motor 22 is used for driving the brush roller 18 to rotate in a plane perpendicular to the up-down direction so as to clean the glass panel 24.

In this embodiment, there are two ways of implementing the cleaning of the glass panel 24 in this disclosure, one way is that when the cleaning mechanism cannot move, after the cleaning mechanism finishes cleaning the surface (i.e. the front surface) of the glass panel 24 moving to the station where the cleaning mechanism is located, the turntable mechanism drives the next glass panel 24 to the cleaning mechanism to clean the front surface of the glass panel 24 through the brush roller 18, and the surface of the glass panel 24 where the front surface has been cleaned is rotated by 180 ° by rotating the plane where the rotating installation position rotates to rotate vertically, so that the front and back surfaces of the glass panel 24 are reversed. The other is that the cleaning mechanism can make a reciprocating motion close to or far from the turntable mechanism, or that the positional relationship between the cleaning mechanism and the turntable mechanism satisfies that the glass panel 24 can be immediately rotated to enable the back surface to be cleaned after the front surface is cleaned, then the glass panel 24 is cleaned one by one in sequence, that is, when the front surface of one glass panel 24 is cleaned, the rotating installation position immediately rotates the front surface by 180 degrees to enable the back surface to be continuously cleaned. Thus, in a specific application, the cleaning mode of the present disclosure is practical.

Specifically, as shown in fig. 1, the bracket 1 includes: go up the splice plate, lower splice plate and connecting plate, go up splice plate and lower splice plate and set up relatively and locate the homonymy of connecting plate, lower carousel 2 rotates through lower carousel connecting rod 6 and lower carousel bearing 7 and installs at lower splice plate, go up carousel 3 and rotate through last carousel connecting rod 4 and last carousel bearing 5 and install last splice plate, lower carousel connecting rod 6 is connected with carousel motor 8 drive, carousel motor 8 installs at lower bearing plate, and be equipped with the backup pad that connects gradually around the lower surface of lower bearing plate, these backup pads enclose to establish and form an installation cavity in order to hold carousel motor 8.

The turntable motor 8 can be directly connected with the lower turntable connecting rod 6, and can also be in driving connection through a transmission mechanism. Of course, in other embodiments, the turntable motor 8 may be in driving connection with only the upper turntable connecting rod 4. When the turntable motor 8 is in transmission connection with the upper turntable connecting rod 4 and the lower turntable connecting rod 6, the upper turntable connecting rod 4 and the lower turntable connecting rod 6 are one turntable connecting rod, or the upper turntable connecting rod 4 and the lower turntable connecting rod 6 are respectively in driving connection with the turntable motor 8, but the two turntable motors 8 need to be synchronously driven to rotate so as to realize synchronous rotation of the lower turntable 2 and the upper turntable 3, and further realize that the glass panels 24 are brought to the stations where the cleaning mechanism is located for cleaning. In other embodiments, the turntable mechanism may include only one turntable or more than two turntables, and when it includes only one turntable, the rotational mounting provided thereon may enable fixation and self-rotation of the glass panel 24 during cleaning. When it comprises a plurality of turntables, the fixing and self-rotation of the glass panel 24 can be achieved by two turntables; it is also possible to achieve a multilayer arrangement of the glass panels 24 in the height direction, thereby improving the single cleaning thereof.
