Description

Technical Field

[0001] This utility model relates to a nail feeding device, and more particularly to a rotary automatic nail feeding device. Background Technology

[0002] In recent years, with the rapid development of the new energy vehicle industry, lightweighting has become a focus for automakers, and corresponding automotive sheet metal joining processes have also developed rapidly. Currently, FDS (Fused Self-Tapping Screw) technology is one of the most frequently used processes in automotive sheet metal joining. FDS products have advantages such as light weight, ease of use, high connection strength, and reliable mechanical properties, meeting the lightweighting needs of automakers. Traditional manual screw handling is prone to errors and inefficient. In the current FDS process, a single screw feeder can only deliver one type of screw to complete the screwing process with the auxiliary mechanism, which is not only slow but also inefficient. To meet the need for simultaneous screwing of multiple screw types, multiple screw feeders are required, which not only takes up a lot of space but also increases subsequent maintenance costs.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] See Figure 1 This utility model discloses a rotary automatic nail feeding device, comprising a nail feeding mechanism 1, a nail picking mechanism 2, and an electrical control box 3. The nail feeding mechanism 1 and the nail picking mechanism 2 are both electrically connected to the electrical control box 3. The nail feeding mechanism 1 includes a nail distribution mechanism 1-1, a rotary feeding mechanism 1-2, a nail suction tube feeding mechanism 1-3, a support rod 1-4, and a base 1-5. The nail distribution mechanism 1-1 is disposed above the rotary feeding mechanism 1-2. The rotary feeding mechanism 1-2 and the nail suction tube feeding mechanism 1-3 are both fixed on the base 1-5. The nail suction tube feeding mechanism 1-3 is located above one side of the rotary feeding mechanism 1-2. Four support rods 1-4 are provided and fixed at intervals on both sides of the base 1-5. The nail distribution mechanism 1-1 is fixed to the top of the support rod 1-4. The nail picking mechanism 2 is fixed on the base 1-5.

[0022] See Figure 2 and Figure 3 The nail feeding and distribution mechanism 1-1 includes a vibratory feeder 1-1-1, a straight material channel nail feeding mechanism 1-1-2, a nail feeding tube distribution plate 1-1-3, and a nail feeding tube 1-1-4. The straight material channel nail feeding mechanism 1-1-2 is rectangular and includes a nail feeding channel 1-1-21 and a fixed outward flange 1-1-22. The nail feeding channel 1-1-21 is configured as… The fixed outer flange 1-1-22 is provided in two forms, respectively fixed to the top two sides of the nail feeding channel and extending beyond the side wall of the nail feeding channel. One end of the straight material channel nail feeding mechanism 1-1-2 passes through the side wall of the vibrating plate 1-1-1 and is fixed thereto. A T-shaped baffle 1-1-5 is provided at the end of the insertion end to prevent the screw from falling back into the vibrating plate from this end. A nail inlet 1-1-6 is provided on one side of the insertion end. The screw in the vibrating plate vibrates and enters the nail feeding channel, and the nail head is stuck in the " The upper end of the straight material feeding mechanism 1-1-2 is shaped with the nail head facing downwards. The other end of the straight material feeding mechanism 1-1-2 is embedded in the nail feeding tube distribution plate 1-1-3. The fixed outer flange 1-1-22 is located above the nail feeding tube distribution plate. The nail feeding tube distribution plate is fixed to the base by the support rod 1-4. The nail feeding tube 1-1-4 is vertically arranged, and its top end passes through the nail feeding tube distribution plate 1-1-3 and is located at the nail outlet end of the straight material feeding mechanism 1-1-2. The screw falls into the nail feeding tube from the nail outlet end. The straight material feeding mechanism 1-1-2 is equipped with a full material sensor 1-1-7 and a material arrival sensor 1-1-8 located outside the vibrating plate and above the nail outlet end, respectively. Material sensors 1-1-8 are fixed on the full material sensor base 1-1-9 and the incoming material sensor base 1-1-10, respectively. Both the full material sensor base 1-1-9 and the incoming material sensor base 1-1-10 are fixed on the outer flange of the top of the straight material feeding mechanism 1-1-2. The bottom end of the feeding tube 1-1-4 is located above the turntable feeding mechanism 1-2. Four sets of vibrating discs, straight material feeding mechanisms, and feeding tubes are simultaneously installed on one feeding tube distribution plate 1-1-3. Each set is equipped with a turntable feeding mechanism 1-2, a suction tube feeding mechanism 1-3, and a nail-picking mechanism 2. The four feeding devices can be configured with different specifications to simultaneously feed four different types of screws.

[0023] See Figure 4 The turntable feeding mechanism 1-2 includes a turntable 1-2-1 and a first synchronous motor 1-2-2. The center of the turntable 1-2-1 is fixedly connected to the first transmission shaft 1-2-3 on the first synchronous motor 1-2-2. The first synchronous motor 1-2-2 is vertically fixed on the base 1-5. The turntable 1-2-1 is horizontally arranged, and its surface is evenly spaced with several recessed positioning holes 1-2-4. The diameter of the recessed positioning holes 1-2-4 gradually decreases from top to bottom. The nail feeding tube 1-1-4 is located directly above the turntable. When the turntable rotates and the recessed positioning holes on it are aligned with the nail feeding tube, the screw falls into the recessed positioning hole. The screw is pre-positioned through the recessed positioning hole, so that the screw is in the correct position.

[0024] See Figure 5The nail suction tube feeding mechanism 1-3 includes a nail suction tube assembly 1-3-1, a second synchronous motor 1-3-2, and a mounting base 1-3-3. The nail suction tube assembly 1-3-1 includes a nail suction tube 1-3-11 and a conveyor belt transmission mechanism 1-3-12. Several nail suction tubes 1-3-11 are provided and are evenly spaced on the conveyor belt of the conveyor belt transmission mechanism 1-3-12. The nail suction tube 1-3-11 is a hollow round tube with a branch pipe. The branch pipe is connected to a vacuum generator through a suction pipe. The second synchronous motor 1-3-2 is connected to the conveyor belt transmission mechanism 1-3-12 through a second transmission shaft. The second synchronous motor 1-3-2 is fixed to the upper end of the mounting base 1-3-3, and the mounting base 1-3-3 is fixed to the base 1-5. The second synchronous motor drives the conveyor belt transmission mechanism to rotate, and at the same time drives the nail suction tube on the conveyor belt to move. When an empty nail suction tube at the end is directly above the sinking positioning hole on the turntable, vacuum suction is applied, sucking the screw in the sinking positioning hole into the nail suction tube. The first and second synchronous motors rotate synchronously, and the nail suction tube that sucks the screw moves upward under the drive of the second synchronous motor. At the same time, the first synchronous motor rotates, driving the turntable to rotate, and the next adjacent sinking positioning hole moves to below the new empty nail suction tube, and the nail suction action is repeated.

[0025] See Figure 6 The rivet removal mechanism 2 includes a laser beam sensor 2-1, a sensing base 2-2, and a cylinder gripper 2-3. There are two sensing bases 2-2 arranged opposite each other, and each sensing base 2-2 is equipped with a laser beam sensor 2-1. The two laser beam sensors 2-1 are arranged facing each other. The gripping opening size of the gripper on the cylinder gripper 2-3 matches the size of the rivet. The cylinder gripper 2-3 is controlled and operated by an external robot.

[0026] Working process: Four different or identical screws are placed in four vibrating discs. Under the vibration of the vibrating discs, the screws enter the screw feeding mechanism of the straight material channel and fall into the sinking positioning hole on the turntable for pre-positioning by the screw feeding tube. The first synchronous motor rotates to perform the screw feeding action. When the turntable rotates to below the screw suction tube assembly, the vacuum generator is activated to suck the screw in the sinking positioning hole into the screw suction tube. The screw suction tube assembly is driven by the second synchronous motor to perform further screw feeding action. When the screw reaches between the two laser beam sensors of the screw picking mechanism, the laser beam sensors detect the screw and transmit the signal to the external robot controller. The robot controller controls the cylinder gripper to move to the screw position to perform the screw picking action, and then moves to the loading position. Finally, the auxiliary equipment drives the screw to rotate to realize the subsequent connection of the board.
