Description

Technical Field

[0001] The utility model relates to a screw driving device, in particular to a relay automatic screw driving device. Background Art

[0002] With the continuous improvement of the degree of automation in modern industry, especially in the electronic equipment manufacturing industry, the requirements for production efficiency, product quality and cost control are becoming increasingly stringent. As a widely used electrical control component, the assembly process of relays in the production process, especially the screw tightening process, has an important impact on the performance stability and service life of the product.

[0003] However, traditional manual or semi-automatic screw driving methods have many limitations, such as low production efficiency, difficult to ensure assembly accuracy, and poor process consistency. In automated production, due to loading reasons, only one screw can be driven in at a time, resulting in low production efficiency. Utility Model Content

The vertical cylinder drives the vertical push block to move along the vertical track. The parallel cylinder drives the parallel push block to move along the parallel track. The parallel track has a first grabbing position and a second grabbing position. The first grabbing position is located at the intersection with the vertical track, and the second grabbing position is located at the other end of the parallel track relative to the first grabbing position. The mounting part grabs the screws located at the first grabbing position and the second grabbing position and installs them on the relay. A rotating mechanism can also be provided to screw the screws into the relay to complete the installation. The screws are placed before the relay is placed in the relay moving mechanism.

[0006] By adopting the above technical solution, during processing, the relay is placed on the relay moving mechanism, and then the relay is moved to the screw feeding mechanism. At this time, the vibration plate transmits the screw to the feeding track until the screw moves to the end of the feeding track and enters the vertical track. The vertical cylinder drives the vertical push block to push the screw to the second grasping position, and then the parallel cylinder drives the parallel push block to push the screw to the first grasping position. After the next screw enters the vertical track, it is moved to the first grasping position by the vertical push block. At this time, there are screws at the first grasping position and the second grasping position. The mounting part grabs the two screws and installs them at the corresponding relay. After installation, the installed relay is removed through the unloading mechanism. Through the above actions, multiple screws can be grabbed at the same time to improve work efficiency.

[0008] By adopting the above technical solution, when the relay is placed in the conveyor belt, the conveyor belt moves the relay to a position relative to the left side of the track, and then the push-pull member pushes the relay into the left side of the track and moves it to the track connection part, and then the push member pushes the relay to the screw feeding mechanism to install the screws, and then moves it to the right side of the track through the push member, and the push-pull member pushes the relay back to the conveyor belt.
