Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, and more specifically, to an automatic material feeding device with magnetic positioning. Background Technology

[0002] In the field of automated assembly of electronic components, the double-sided PCB board mounting process requires the feeding device to ensure that materials with distinct front and back sides are accurately conveyed in a uniform orientation. Traditional vibratory feeder systems generally use mechanical stops, optical inspection, or centrifugal screening to correct the material posture.

[0003] The closest existing technology is disclosed in patent announcement number CN211687088U, "Automatic Feeding Device for Inductor Bodies," which includes a base, a material tray, a vibration motor installed below the material tray, a spiral feeding track and a discharge track located in the middle of the material tray. The discharge track includes two parallel track belts with a material clamping gap between them. The width of the material clamping gap is greater than the upper width of the inductor and less than the lower width of the inductor. The discharge track is provided with a first adjustment part and a second adjustment part in sequence. The first adjustment part includes an arc-shaped track belt and an air blowing pipe arranged in parallel. The second adjustment part includes a baffle connected to the outer end of the discharge track, an air blowing pipe located at the front end of the baffle, and a track notch located in the baffle. The length of the track notch is greater than the width of the inductor. The inner side of the baffle is provided with a slot.

[0004] Existing feeding devices still rely on purely mechanical / pneumatic correction, resulting in low feeding accuracy and failing to solve the problem of random material flipping.

[0005] In view of this, the present invention proposes an automatic material feeding device with magnetic positioning that is not prone to jamming. Utility Model Content
