Pick and place device for mouse roller module

The present invention relates to an automated assembly device, in particular to a pick and place device for a mouse wheel module, which can be arranged in a mouse automatic assembly production device for picking up a roller module having a torsion spring.

Known automated assembly equipment, typically comprising a plurality of automated assembly workstations arranged along the product assembly line, and carriers that can be moved along the product assembly line to carry the product, using these automated assembly workstations to separate different products The components are automatically assembled on the passing vehicles in order. In order to have the capability of Flexible Manufacturing System (FMS) to be used for automated assembly of different types of products, a common method is to computerize The combination of industrial control systems and robotic arms or automated assembly robots enables automated assembly of different types of products, as robotic or automated assembly robots often have multi-joint or multi-degree of freedom (eg multiple The axis robot), therefore, when the product type is replaced, the automatic assembly of the robot can be controlled by the updated control program, and the automatic assembly of the new product can be performed by the updated control program, but the cost of the automatic assembly device is still partial. high.

For example, the mouse used in a personal computer (PC), due to the brand and type of the mouse, most of the mouse components do not have uniform specifications and sizes, the mouse shape and sliding of each manufacturer's design The assembly method or structural characteristics of the mouse components (such as the mouse wheel module) are also not identical. Therefore, the final assembly steps in the current mouse production process are still manual assembly, manual assembly. In addition to the need to employ a large amount of labor, the production capacity is also limited by the number of manpower. Although increasing manpower can increase production capacity, it will also increase the cost of production. Compared with other high-priced electronic products, the unit price of the mouse is relatively Very low, for the mouse manufacturers whose production cost is not easy to reduce and the production capacity is difficult to improve, how to automatically assemble the mouse by using automated assembly equipment, thereby reducing production costs and increasing production capacity has been one of the goals of the industry.

In practice, one of the technical problems to be overcome in the automated assembly of the mouse wheel module is that the structure of the different types of mouse wheel modules is usually not the same, and the mouse wheel is known to be scrollable. In addition, there are usually button functions, especially many roller modules are also designed with a torsion spring. The roller based on the roller module is easy to rotate due to external force in the normal state, and the torsion spring is assembled to the position on the other hand (usually assembled in The mouse base is also in a state of free movement. Therefore, when using the automated assembly equipment to pick up and place the roller module, how to accurately clamp the roller module and keep the roller and torsion spring in it, it needs to be overcome. One of the technical problems; in addition, for different types of roller modules that have torsion springs, how to design a fixture or tool that is low-cost and can elastically change the pick-and-place device is another need to overcome The problem.
