Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to an automatic assembly equipment for steel ball spring assemblies. Background Technology

[0002] Ball bearing spring assemblies are core functional units of low-voltage electrical components. In the manufacturing process of low-voltage electrical components, the assembly of ball bearing spring assemblies, as the core unit for achieving key functions such as switch elastic reset and contact on / off buffering, has long suffered from the following significant drawbacks in terms of efficiency and quality: The small size of the ball bearings and springs means that they are currently mostly assembled manually using tweezers and suction pens, with the assembly time for a single component often exceeding 30% of the total assembly time. This is especially true for multi-contact switches, where multiple sets of ball bearings and springs need to be installed sequentially, making the process lengthy and difficult to perform in parallel, resulting in low assembly efficiency. During manual or semi-automatic pressing, the ball bearings may not fall accurately into the center of the spring end face, causing the spring to bend or be squeezed out laterally after being compressed. Alternatively, repeated collisions between the ball bearings and metal clamps or material channels during assembly can cause scratches or indentations, increasing surface roughness and making it prone to jamming during sliding, resulting in switch reset sticking and inconsistent contact overtravel.

[0003] In view of this, there is an urgent need to design an automatic assembly equipment for steel ball spring assemblies to solve the technical defects in the assembly process of existing steel ball spring assemblies. Utility Model Content
