Automatic screw-in device for screws

Abstract

The invention relates to an automatic screw-in device for screws. The automatic screw-in device (1) for the screws comprises a screw conveying mechanism (10) used for conveying the screws (50) one by one, a screw keeping mechanism (20), a workpiece table (30) carrying a workpiece (60), and a screw screw-in mechanism (40). The screw keeping mechanism (20) contains the screws (50) output from an outlet (101) of the screw conveying mechanism (10) and keeps the postures of the screws (50). The screw screw-in mechanism (40) is used for screwing the screws (50) in the workpiece (60). The screws (50) are moved to the screw-in position (A) on the workpiece (60) from the outlet (101) of the screw conveying mechanism (10) in the state that the postures of the screws (50) are kept by the screw keeping mechanism (20) and the screws (50) are connected with the screw screw-in mechanism (40) in an abutting manner, and then the screws (50) are screwed into the workpiece (60) by the screw screw-in mechanism (40) in the state that the screws (50) are not kept by the screw keeping mechanism (20).

Description

technical field [0001] The invention relates to an automatic screw screwing device. Background technique [0002] Conventionally, the following two types of automatic screw-in devices have been adopted. That is, if figure 1 As shown, blow the screw along the screw pipe to the screw chuck by blowing through the pipeline, and then tighten the screw with the screwdriver. Additionally, if figure 2 As shown, the screw is sucked by vacuum suction, and then the screw is tightened by the bit. [0003] However, in the way of blowing through the pipeline, because the screw may be stuck or even turned over in the pipeline, the supply of screws with very short threads cannot be realized. In the vacuum adsorption mode, the vacuum suction rod structure is generally set on the elastic mechanism on the batch nozzle, which has limitations, so the screw screwing stroke cannot be too deep. In addition, in the vacuum suction method, the bottom of the screw is not supported, so the screw i...

Problems solved by technology

[0003] However, in the pipeline blowing method, because the screw will be stuck or even turned over in the pipeline, it is impossible to supply screws with very short threads

In the vacuum adsorption mode, the vacuum suction rod structure is generally set on the elastic mechanism on the batch nozzle, which has limitations, so the screw screwing stroke cannot be too deep

In addition, in the vacuum suction method, the bottom of the screw is not supported, so it is easy to deflect the screw due to vibration during the process

[0004] In this way, in the existing automatic screw screwing device, because the screws all have lost the state of precise positioning, an unstable posture will be generated, which has a great impact on the stability of the automation equipment, and this has a great influence on the stability of many automation equipment. The design of the scheme has brought great limitations
