## Abstract

A cap rotation device includes a cap rotator, a liquid transferring device and an optical detecting device. The liquid transferring device is disposed near the cap rotator, and the optical detecting device is disposed between the cap rotator and the liquid transferring device. The optical detecting device is used to detect a position of a sealing cap of a chemical drum to guide the cap rotator aligning with the sealing cap. Therefore, the sealing cap is opened by the cap rotator, and then the chemical liquid is transferred by the liquid transferring device.

## Claims

### Claim 1

A cap rotation device, comprising:
a cap rotator;
a liquid transferring device disposed near the cap rotator;
an optical detecting device disposed between the cap rotator and the liquid transferring device, wherein the optical detecting device detects a position of a sealing cap of a chemical drum to guide the cap rotator aligning with the sealing cap, the cap rotator opens the sealing cap and the liquid transferring device transfers a chemical liquid;
a fixing plate;
two vertical moving devices respectively connected between the fixing plate and the cap rotator, and the fixing plate and the liquid transferring device to vertically move the cap rotator and the liquid transferring device respectively; and
two horizontal moving devices connected to the fixing plate to horizontally move the fixing plate.

### Claim 2 (depends on 1)

The cap rotation device of claim 1, wherein the liquid transferring device comprises a liquid extractor to extract the chemical liquid from the chemical drum.

### Claim 3 (depends on 1)

The cap rotation device of claim 1, wherein the liquid transferring device comprises a liquid reflux device to flow the chemical liquid back to the chemical drum.

### Claim 4 (depends on 1)

The cap rotation device of claim 1, further comprising:
an isolating plate; and
two elastic isolating shields connected to the isolating plate and the fixing plate to isolate an evaporated chemical gas of the chemical drum.

### Claim 5 (depends on 4)

The cap rotation device of claim 4, further comprising:
a first motor driving the liquid transferring device to couple the liquid transferring device to an opening of the chemical drum.

### Claim 6 (depends on 5)

The cap rotation device of claim 5, further comprising:
a second motor driving the cap rotator to open or close the sealing cap from the opening of the chemical drum with the cap rotator.

### Claim 7 (depends on 6)

The cap rotation device of claim 6, wherein the first motor and the second motor comprise torque motors.

### Claim 8 (depends on 7)

The cap rotation device of claim 7, further comprising:
a liquid transferring pipe connected to the liquid transferring device to directly transfer the chemical liquid through the opening of the chemical drum.

### Claim 9 (depends on 8)

The cap rotation device of claim 8, wherein each of the vertical moving devices comprises an air cylinder and a position detecting device to detect a working position of the air cylinder, and the cap rotator and the liquid transferring device adopt corresponding cap opening connectors to engage with the sealing cap according to a type of the sealing cap of the chemical drum.
