Description

Technical Field

[0001] The utility model relates to a shelf, in particular to a SMT material tray horizontal shelf, belonging to the technical field of SMT intelligent warehousing. Background Art

[0002] SMT electronic assembly technology achieves high-density assembly of components by directly mounting electronic components with no pins or short pins on the surface of printed circuit boards (PCBs), greatly reducing the volume and weight of circuit boards. It is an indispensable part of modern electronic manufacturing and is widely used in the manufacturing process of various electronic products. SMT technology has significant advantages, including high reliability, high efficiency, and low cost. SMT smart warehousing achieves efficient management of materials through intelligent means, including precise positioning of materials, fast picking, and real-time monitoring. It uses the Internet of Things technology to connect hardware devices such as smart shelves, AGV carts, and RFID readers with existing ERP, MES and other systems to achieve real-time interaction and sharing of information.

[0003] Existing SMT smart shelf designs mostly adopt the method of placing SMT trays vertically, and are equipped with smart LED lights and QR codes under the shelves to identify the presence of trays. However, due to the large spacing between tray slots (usually 20 mm or more) and the thin thickness of SMT trays (8-11 mm), the trays on the shelves are not always completely vertical, and sometimes they may be tilted. This tilted state may cause adjacent SMT trays to cross each other. Further, due to the effect of gravity, the two attached edges of the vertical SMT trays will be stretched apart, causing trouble for subsequent manual or automatic pick-and-place operations. For this reason, a horizontal shelf for SMT trays is proposed. Utility Model Content

[0004] In view of this, the utility model provides a horizontal shelf for SMT trays to solve or alleviate one of the technical problems existing in the prior art and at least provide a beneficial choice.

[0006] An internal support assembly is arranged inside the main body assembly. The internal support assembly includes internal support cross beams, internal support main beams, and internal support auxiliary beams. Four internal support main beams are symmetrically and fixedly connected to the inner side wall of the internal support cross beam, and four internal support auxiliary beams are symmetrically and fixedly connected to the inner side wall of the internal support cross beam.

[0007] Further preferably: The internal support cross beam is detachably and fixedly connected to one side of the positioning rod.
