This application claims the benefit of the filing date under 35 U.S.C. ยง 119(a)-(d) of Chinese Patent Application No. 201711011254.3, filed on Oct. 25, 2017.
The present invention relates to an unloading system and, more particularly, to an unloading system for a rotatable table.
An assembly process of a product usually includes a number of steps and, in order to improve assembly efficiency, the product may be positioned on a rotatable table. The rotatable table rotates the product loaded on it to various assembly stations to complete the assembly of the product. After the product is assembled, the assembled product is rotated by the rotatable table to an unloading station where an operator unloads the assembled product from the rotatable table and visually checks whether the quality of the assembled product meets a qualification standard.
It is, however, inefficient to manually unload the assembled product from the rotatable table. Furthermore, visually inspecting the product for quality of assembly is not only inefficient but is also unreliable.
An unloading system comprises a rotatable table configured to be rotatable about a vertical axis parallel to a vertical direction, a plurality of fixing devices mounted on the rotatable table around a periphery of rotatable table and separated from each other, and a manipulator adapted to grip a product fixed on each of the fixing devices and move the gripped product to a predetermined position. The rotatable table is adapted to rotate the plurality of fixing devices mounted thereon into a work area of the manipulator one by one and the manipulator is adapted to unload the product from each of the fixing devices one by one.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
An unloading system according to an embodiment is shown in
The rotatable table 100, shown in
The manipulator 300, shown in
The unloading system, as shown in
The product 10 to be detected may comprise a connector including a housing and a contact inserted into the housing. In an embodiment, the sensor 400 is a non-contact distance sensor for detecting whether a depth of insertion of the contact into the housing is equal to a predetermined depth. In an embodiment, a plurality of contacts are inserted into the housing, and the manipulator 300 is adapted to move the plurality of contacts one by one to a position below the sensor 400, so as to detect whether the depth of each contact inserted into the housing is equal to the predetermined depth.
In another embodiment, the sensor 400 is a visual sensor for detecting whether an external appearance of the product 10 meets a predetermined requirement. For example, the sensor 400 may comprise a camera. The product 10 may have a plurality of external appearance areas to be detected, and the manipulator 300 is adapted to move the plurality of external appearance areas of the product 10 one by one to a position below the sensor 400, so as to detect whether each external appearance area of the product 10 meets the predetermined requirement.
