Vibratory Weld Nut Automatic Screw Bowl Feeder Machine

Vibratory Weld Nut Automatic Screw Bowl Feeder Machine

Product Introduction:

The nut conveyor's technical foundation relies on vibratory feeding and precise guidance systems. Its operational process follows a meticulously coordinated mechanical sequence: “sorting, orienting, separating, conveying, and positioning.” Initially, bulk nuts are organized into orderly arrangements, with posture alignment accomplished via specialized spiral tracks inside the vibrating bowl. They are then transported smoothly by a linear vibratory feeder. Finally, individual nuts are separated from the track and accurately delivered—using either high-pressure air jets or mechanical pick-and-place mechanisms—directly above the workpiece’s threaded hole, where they await the tightening operation by the actuator.

Transportation Pipeline: It is usually a flexible hose made of polyurethane or nylon material, with quick couplings at both ends. As an exclusive track connecting the host and the workstation. After the separated individual nuts enter the pipeline, they will be pushed by compressed air (blowing type) or mechanical mechanism (pushing type) that opens instantly, flying at high speed inside the pipeline and reaching the feeding nozzle at the end. Its flexibility ensures that it can bend freely with the robotic arm or moving mechanism.

Vibration disk/Hopper: It is a bowl shaped container with a spiral ascending track inside. By using electromagnetic force or motor drive to generate high-frequency micro amplitude vibration, the stacked nuts are used to climb in an orderly manner along a spiral track. During this process, the nuts will be oriented through specific track structures (such as notches, stops, blow holes, etc.) to ensure that all nuts enter the next stage in a uniform posture (such as threaded holes facing up/down). It is like the "heart" of the system, providing stable and orderly "blood" (nut) for subsequent processes.

Direct Vibration Feeder: A linear vibration track, usually separated from but tightly connected to the vibration disc base. It serves as a 'buffer and acceleration channel'. Receive the directional nut gushing out from the outlet of the vibrating disc, and through its own linear vibration, smoothly and continuously transport the nut to the next stage - the separation mechanism. It can effectively eliminate congestion at the outlet of the vibrating disc and provide stable and uniform nut flow for separation.

Pneumatic System: Including gas source interface, filter, pressure reducing valve, oil mist device (triple piece), and solenoid valve. The 'power muscles' that make up the device. Provide clean, dry, and pressure stable compressed air. This airflow is both the "power source" that drives the nut to move at high speed inside the pipeline, and may also be the "driver" that drives the cylinder type separation mechanism.

Supporting Point Projection Welding Machines:

The nut conveyor and fixed spot welding machine are typically connected in series within automated production lines, forming an efficient nut welding unit. Their collaborative process is as follows: First, the nut conveyor uses a vibratory bowl for orientation and alignment, precisely blowing nuts through pneumatic tubes onto the positioning pins of the welding gun electrode head. Next, the spot welding machine drives the upper electrode to descend, ensuring the workpiece and nut are tightly pressed together, while the internal clamping device of the conveyor supports the nut from the rear to prevent displacement. Finally, the spot welding machine applies a high instantaneous current, causing the nut's welding protrusion and the workpiece contact surface to melt instantly, forming a weld nugget and achieving permanent fixation. The entire process is coordinated via PLC signals, enabling seamless integration of automatic nut feeding, precise positioning, and high-strength welding, significantly improving production cycle time and welding quality consistency.
