Description

Disk type screw pick and place device

The present disclosure relates to a screw pick-and-place device, and more particularly to a disk-type screw pick-and-place device.

Locking the screws on the workpiece is a common way of combining objects. It is often necessary to lock at least three to four screws and dozens of screws in one workpiece. Conventional assembly lines often require manual locking of the screws, which requires a lot of manpower and unstable locking quality. Therefore, an automatic locking screw mechanism has been developed to replace manual work.

Although the locking action of the automatic locking screw mechanism is faster than manual and the quality is better, the automatic locking screw mechanism needs to be returned to the discharge port of the screwing machine again after each screw is locked. One screw, so that its locking efficiency is greatly reduced.

In this regard, there is also a device that automatically feeds the screwdriver bit, which greatly improves the locking efficiency. This type of equipment uses a blown hose to screw the screw from the discharge port of the screw machine to the screwdriver of the screwdriver. head. However, this type of equipment is not suitable for all screws. Screws that are too long or too short are not suitable, and no obstacles are required in certain areas of the keyhole of the workpiece.

However, most of the 3C electronic products are light and thin, and the screws used are short and the parts are dense. Therefore, it is difficult to clean the area of the keyhole of the workpiece for locking the screw, so that the air blowing type automatic feeding cannot be applied. This reduces the efficiency of automatic locking.

Therefore, how to overcome the problems of the above-mentioned prior art has become a problem that is currently being solved.

In view of the above-mentioned various deficiencies of the prior art, the present disclosure provides a disk-type screw pick-and-place device comprising: a screw pan with a connected turntable and a first rotating body, the turntable having a screw placement portion Positioning a screw, the first rotating system rotates the turntable according to the first rotation direction to transfer the screw placed on the screw placement portion to a predetermined take-out position; and the screw pick-and-place mechanism has a connected screw receiving material An arm and a second rotating body, the screw take-up arm grasps a screw that is conveyed to the take-out position, and rotates the screw take-up arm from the second rotating body in a second rotation direction, and the screw is taken out The screw grasped by the arm is transferred to a predetermined working position for use by a screwdriver.

It can be seen from the above that the disk-type screw pick-and-place device of the present disclosure mainly uses the screw pan and the screw pick-and-place mechanism to operate the screw to temporarily supply the screw to the screwdriver, thereby shortening the screw driver to obtain the screw. Time, which in turn increases the efficiency with which the screwdriver locks the screw to the workpiece.
