Liquid tank rotating device

Abstract

A liquid tank rotation device includes: a lifting module, comprising a base plate that is driven to rise and fall by a lifting drive unit, and adapted to insert a liquid tank from the top through a perforation in the base plate when the base plate is lowered; an image recognition module, adapted to acquire an image of the top of the liquid tank by a camera unit located above the base plate, and to determine a rotation angle of the liquid tank based on the image; and a clamping module, comprising a guide rail surrounding the perforation, a plurality of telescopic clamps movably disposed on the guide rail and located below the base plate, the plurality of telescopic clamps being adapted to clamp the liquid tank, and an actuator adapted to actuate the plurality of telescopic clamps to synchronously displace relative to the guide rail according to the rotation angle, so that the liquid tank rotates accordingly.

Claims

1. A liquid tank rotation device, comprising: a lifting module including a base plate and a lifting drive unit, the lifting drive unit being used to drive the base plate to lift and lower, the base plate having a through hole and being adapted to allow a liquid tank to be inserted from the top through the through hole when the base plate is lowered; an image recognition module adapted to acquire an image of the top of the liquid tank by a camera unit located above the base plate, and to determine a rotation angle of the liquid tank based on the image; and a clamping module including a guide rail, a plurality of telescopic clamps and an actuator, the guide rail being circumferentially disposed around the through hole, the plurality of telescopic clamps being movably disposed on the guide rail and located below the base plate, the plurality of telescopic clamps being adapted to jointly clamp the liquid tank, and the actuator being adapted to actuate the plurality of telescopic clamps to synchronously displace relative to the guide rail according to the rotation angle, so that the liquid tank rotates accordingly.

2. The liquid tank rotating device as described in claim 1, wherein, The lifting drive unit includes several linear actuators, the outputs of which are respectively connected to opposite sides of the substrate.

3. The liquid tank rotating device as described in claim 1, wherein, The plurality of telescopic chucks are coupled to at least one arc-shaped rack, which has a sliding portion and a meshing portion. The sliding portion is slidably connected to the guide rail. The actuator includes at least one gear that meshes with the meshing portion of the arc-shaped rack.

4. The liquid tank rotating device as described in claim 3, wherein, The meshing part is located on the outer circumferential surface of the arc-shaped rack.

5. The liquid tank rotating device as described in claim 3, wherein, The free end of the guide rail extends downwards and forms an inverted T-shape for the sliding part of the arc-shaped rack to connect.

6. The liquid tank rotating device as described in claim 1, wherein, Each telescopic chuck is coupled to an arc-shaped rack, which has a sliding part and a meshing part. The sliding part is slidably connected to the guide rail. The actuator includes several gears, each of which meshes with the meshing part of the corresponding arc-shaped rack.

7. The liquid tank rotating device as described in claim 6, wherein, The central angle of the arc-shaped rack is less than or equal to 90 degrees.

8. The liquid tank rotating device as described in claim 1, wherein, The guide rail is fixed to the substrate, and the guide rail forms a closed ring.

9. The liquid tank rotating device as described in claim 1, wherein, The guide rail is fixed to the base plate. The guide rail is configured into several unconnected sections that surround the periphery of the perforation, according to the required travel of the telescopic clamps.

10. The liquid tank rotating device as described in any one of claims 1 to 9, wherein, The camera unit captures images necessary to determine the rotation angle only after the liquid tank is gripped by several telescopic clamps.
