Description

An intelligent self-locking device for the feeder material tray of a closed type anti-error placement machine on an SMT production line Technical Field

[0001] The present invention relates to the field of SMT technology, and in particular to an intelligent self-locking device for a material tray of a closed-type error-proof placement machine FEEDER on an SMT production line. Background Art

[0002] The intelligent self-locking device of the material tray of the SMT production line's intelligent closed-type error-proofing placement machine FEEDER needs to intelligently lock material trays of different specifications. During the material connection and replacement process, it can intelligently open and close the lock and perform identification according to the instructions issued by the error-proofing system. When the number of the material being replaced is consistent with the material number on the placement machine FEEDER, the intelligent self-locking system of the placement machine FEEDER material tray will automatically unlock the material tray. When the number of the material being replaced is inconsistent with the material number on the placement machine FEEDER, the intelligent self-locking device of the placement machine FEEDER material tray can neither unlock the material tray nor close it when disconnected, and can promptly feed back the information to the error-proofing system to issue an error alarm. To complete the above functions, the intelligent self-locking system of the placement machine FEEDER material tray must meet the following technical conditions:

[0003] 1. During the SMT production line, machine models are often switched based on production and customer needs. To completely prevent material errors, all materials and material trays on the SMT feeder must be cleared each time the machine model is switched. However, material errors may still occur due to incomplete clearance. To avoid this, the intelligent self-locking device of the feeder material tray must be able to automatically detect whether there is a material tray on the feeder.

[0004] 2. The material tray thickness of the SMT production line usually has various specifications such as 8mm, 12mm, 24mm, 36mm, 44mm, 72mm, 88mm, etc. The intelligent self-locking device of the FEEDER material tray of the placement machine must be able to quickly and intelligently merge and split the stations by extracting or inserting station partitions according to the thickness of the material tray in production to meet the needs of different material tray thicknesses.

[0005] 3. The diameter of SMT material trays has various specifications such as 7 inches, 13 inches, and 15 inches. The intelligent self-locking device of the FEEDER material tray of the placement machine must be able to meet the storage and locking needs of material trays of all different diameters at the same time, and also realize the convenient and quick storage and removal of material trays in a limited space.

[0006] 4. The intelligent self-locking system of the FEEDER material tray of the placement machine must be able to intelligently open and close the lock according to the instructions issued by the anti-wrong material system, and promptly identify the correct and incorrect materials.

[0007] In order to achieve the above technical conditions, the present invention proposes an intelligent self-locking device for the material tray of a closed-type anti-error placement machine FEEDER in an SMT production line. Technical issues
