Description

Technical Field

[0001] The invention relates to the technical field of screw dividing, and in particular to a projection welding screw dividing device. Background Art

[0002] In the current design of metal structural parts for automobiles and household appliances, metal parts or nuts and screws are directly projected onto another part. This method has been widely used, especially in the design of automobile frame structural parts, to improve production efficiency.

[0003] There are two major categories of convex welding screws, including welding points below the big head and welding points above the big head. Different material distribution mechanisms are used to distribute the materials one by one for the welding points below the big head and welding points above the big head according to their characteristics. Most of the existing material distribution mechanisms have to be connected to the track outside the vibration plate, which is generally inclined by 45° to 60° to facilitate the sliding of the screws. According to Chinese patent CN215158659U, a screw feeder is disclosed. During the sliding process, the device will have a large head of the nut, which will accumulate and jam the material, and the screw will not slide smoothly. During use, the screw will stay on the track, and the working rhythm will be affected. It must be manually removed before it can continue to be used. Secondly, the screw slides to the bottom and the permanent magnet absorbs the screw. If the large head surface of the screw is not flat, the small head of the screw will not be perpendicular to the surface of the upper cover, and the screw foot will be tilted. When the horizontal push cylinder is extended, the screw will be stuck in the inner vertical plate, causing the screw to be unable to be sent out.

[0004] Therefore, it is necessary to develop a projection welding screw material dividing device to solve the above problems. Utility Model Content

The feeding channel can receive the projection welding screws dropped through the feeding port, and then move toward the blowing pipe and the discharging pipe. The two ends of the feeding channel are respectively connected to the blowing pipe and the discharging pipe.

[0009] Furthermore, the feeding part includes a supporting plate, which extends into the feeding channel to receive the projection welding screws dropped through the feeding port, and when moving toward the blowing pipe and the discharge pipe, the supporting plate gradually moves downward.

[0010] Furthermore, the support plate is recessed inward from the top to form a material receiving groove, and the material receiving groove is located in the material conveying channel and is used to receive the projection welding screws.

[0011] Furthermore, the frame has a guide groove, and a guide rod is provided at the bottom of the supporting plate. The guide rod extends into the guide groove, and the supporting plate is located in the material conveying channel through the guide rod.

[0012] Furthermore, one end of the guide groove is located below the feed port, and the other end extends horizontally for a distance and then extends obliquely downward to below the blowing pipe and the discharge pipe.
