[0006] Furthermore, the vertical vibrating feeder has a four-channel feeder plate above it and a vertical feeding vibrator below it. The feeder plate of the vertical vibrating feeder is connected to the transfer frame for feeding, and the linear module is mounted above the transfer frame.

[0007] Furthermore, the rear side of the transfer frame is a positioning platform with a positioning cavity. The positioning platform is connected to the material channel plate of the direct vibration feeding frame for material storage. The middle section of the transfer frame is a transfer platform. On both sides above the transfer platform, there are shaping clamps that open and close left and right, driven by shaping cylinders. There is an adhesive tank above the front end of the transfer frame and an adhesive applicator below the front end of the transfer frame.

[0008] Furthermore, the glue-dipping cylinder of the glue-applying frame is fixedly installed below the front end of the transfer frame, and a glue-applying clamp that opens and closes to the left and right is installed above the glue-dipping cylinder.

During the initial loading, the linear module drives the picking rack to slide until the picking cylinder on the rear side of the picking rack is above the positioning platform of the transfer rack. The lifting cylinder of the lifting frame drives the picking rack to descend. The picking cylinder on the rear side of the picking rack is activated, extending the picking rod out of the release sleeve. The picking rod inserts into the material on the positioning platform to tighten and pick up the material. The lifting frame drives the picking rack to rise, and the material tightened by the picking rod is released from the positioning platform.

The dipping cylinder starts to rise, driving the glue applicator clamping strip to disengage from the glue tank and the two sides of the material tightened by the picking rod of the picking cylinder on the front side of the picking frame. The glue applicator cylinder starts to drive the glue applicator clamping strip to clamp and adhere the bottom side wall of the material tightened by the picking rod of the picking cylinder on the front side of the picking frame. After applying glue, it resets. The dipping cylinder pulls back the glue applicator clamping strip and soaks it back into the glue tank. After the glue application is completed, the linear module drives the picking frame to slide forward until the picking cylinder on the front side of the picking frame slides to above the material support frame. The material support frame's material support cylinder... The cylinder drives the material support platform to rise and support the assembled materials. The lifting cylinder of the lifting frame drives the material picking frame to fall.
