Description

Technical Field

[0001] The utility model belongs to the technical field of locking screws, and in particular relates to a blowing, sucking and screwing mechanism for screws with a small aspect ratio. Background Art

[0002] Screws with small aspect ratios are prone to jamming when fed using traditional blow-nail feeding mechanisms, making it impossible to feed screws normally. In addition, some products have deep holes, and traditional blow-nail feeding mechanisms are unable to deliver the screws to the screw-locking position. The traditional method of sucking the screws and then locking them requires a long time for the fixture to move, affecting the screw-locking rhythm.

[0003] When using the traditional blow-nail feeding mechanism for small-diameter pen screws, the screws are easily stuck in the nail feed channel, resulting in a high failure rate during the locking process, affecting equipment efficiency. In addition, the fixture movement route is long and the movement time is long during the process of sucking the screws and then locking the screws, which affects the rhythm of locking the screws and leads to low equipment production efficiency.

[0004] In response to the existing problems, we propose a blowing, sucking and screwing mechanism for screws with a small aspect ratio. Utility Model Content

[0055] The nail feeding machine blows the screws into the nail feeding tube 14, and the air cylinder 11 transports the first tube 12 to the bottom of the second tube 13. The first sensor senses that the first tube 12 has reached the bottom of the second tube 13. The nail feeding machine blows air into the nail feeding tube 14 for a specific time. The screws in the nail feeding tube 14 pass the chamfered position and enter the channel 34 of the clamping mechanism. The first tube 12 and the nail feeding tube 14 retract under the action of the first power component 11 until the first tube 12 reaches the top of the second tube 13. After the second sensor senses it, the first power component 11 stops moving. Driven by the third power component 24, the guide rod 25 descends and sucks the screw under the action of the nail suction cylinder 5 and compressed air. After sucking the screw, the screwdriver rod 23 descends to the screw locking position. Driven by the second power component 22, the screwdriver rod 23 and the electric screwdriver head tighten the screw.

[0056] The next time you lock the screw, repeat the above process.
