Vibration feeding tray screening structure

The present invention relates to a technical field of a vibrating feeder, and more particularly to a screening structure of a vibration feeding tray capable of improving the efficiency of screening work.

According to the general disc type vibrating feeder, an array vibration mechanism (such as a piezoelectric element) and a spring piece are arranged between the base and the feeding disc, so that when the vibrating mechanism vibrates, the feeding disc can be driven to approach the reciprocating The motion of rotation.

The structure of the feeding disc is generally a shape in which the central portion is slightly swelled and extends obliquely to the periphery, and then extends obliquely upwards to the periphery, that is, the cross section of the feeding disc is slightly W-shaped, and A spirally rising feed track is recessed along the inner wall of the feed disc near the lowest point of the feed disc so that the part is conveyed along the feed track under the vibration of the feed disc.

Please refer to the new patent for the component reversing device of the vibrating feeder No. M279623 and the new patent for the conveying structure of the vibrating feeder No. M325319. It can be found from the illustrations of the two novel patents that this type of vibrating feeder for screening electronic parts usually only has a single spiral feeding track in the feeding disc, and the length of the feeding track is extended to Even more than two laps, it is convenient to arrange multiple parts screening structures in a feeding track of sufficient length to achieve effective screening of parts.

However, the materials to be screened (electronic parts) are successively advanced along a single feed track and are divided during the process of being transported forward. The segments are screened so that the materials (electronic parts) that are finally sent out by the feeding track are transported at intervals. Such object screening efficiency is obviously insufficient in today's high efficiency, and there is further improvement. necessary.

In view of this, the main purpose of the present invention is to solve the above problems and provide a screening structure for vibrating feed trays, which is provided with two or more sorting paths and guiding paths along the circumference of the feeding disc, and respectively set steering grooves and The discharge port is used to separately screen the objects, and the objects after the screening of the paths are collected and unified, thereby achieving the purpose of improving the efficiency of the screening work.

In order to achieve the above purpose, the present invention mainly forms a feeding path along the periphery of the vibrating feeding tray for conveying the object, and a screening structure is arranged in the feeding path for screening the object, the screening structure is at least filtered by a diversion section. The segment is composed of an output segment; the split segment has two or more divided paths, so that the object is divided into multiple columns; the screening segment respectively has a guiding path corresponding to each of the divided paths of the splitting segment, and each guiding One end of the guiding path is respectively connected to each of the divided paths, and at least one steering groove is disposed at a portion relatively far from the separated path; the output segment is located at a portion of the screening segment away from the center of the vibration feeding tray to connect the respective steerings The trough outputs the object, and the output section extends beyond the screening section, and the output section is provided with a plurality of discharge openings for discharging the object with poor posture.

Since the multi-column sorting path in the screening structure of the present invention can divide the objects into multiple columns and carry them forward at the same time, the transportation efficiency can be improved, and each guiding path is respectively provided with a steering groove to respectively convert the arrangement of the objects. Direction, when the objects are turned, they are respectively transferred into the conveying path, and are separately screened by the respective discharging ports, and finally collected and sent out, thereby achieving the purpose of improving the screening work efficiency.
