Description

Technical Field

[0002] The vertical rotation motion device is a device that realizes the combination of vertical motion and rotational motion. This device is mainly used in the medical industry and the 3C industry, such as the bottling and sealing of pills, the placement of electronic components, and product assembly. It is particularly widely used in situations where the sucked material needs to be moved up and down and rotated.

[0003] The first type of existing vertical rotation motion device uses a non-standard design combination of two motors with splines and synchronous pulleys. This method has the following disadvantages: 1. The non-standard design is relatively wide and not compact; 2. It lacks a housing and cannot be used in applications requiring protection or sealing; 3. The air pipes are exposed, and there are many cable harnesses, making wiring inconvenient; 4. The products are not highly interchangeable and cannot be replaced by each other in different industries. The second method uses an integrated method that uses a linear motor for vertical motion and a servo motor for rotation. This method has the following disadvantages: 1. The linear motor process is relatively complex and requires an unencapsulated encoder for position feedback, which results in high overall cost; 2. The assembly process is complex.
