Description

Technical Field

[0001] The utility model relates to the technical field of patch feeding, in particular to a visual auxiliary feeding device. Background Art

[0002] SMD technology is one of the mainstream technologies and processes in current electronic technology. Small electronic devices are attached to circuit boards through SMD machines, making circuit boards more precise, smaller and lighter. Most SMDs are carried and transported by placing them in a carrier tape. There is a carrier tape position that is suitable for the SMD. The SMD is placed in the SMD carrier tape position and is used by sucking the SMD in the carrier tape position. Therefore, the loading process of the carrier tape is also an indispensable part of the SMD process. In the prior art, loading is generally done by sucking the bulk SMD materials through a suction nozzle and moving them to the designated carrier tape position for placement. When it comes to some SMDs that are not regular rectangular in shape, especially L-shaped materials, it is difficult for the existing suction nozzle to accurately load such SMDs, especially when the SMD has the characteristics of two surfaces, the conductive surface and the non-conductive surface, and the conductive surface needs to be placed on the carrier tape position when placed. When the non-conductive surface is set upright, the traditional suction nozzle loading becomes very difficult, and it is impossible to ensure that each material can be placed as required. The traditional suction nozzle cannot guarantee the efficiency and quality of material feeding. Utility Model Content

[0003] Therefore, the utility model proposes a visually assisted feeding device. For materials with different features on two sides, the device judges the features of the two sides of the material when it is fed into the feeding belt by setting a visually assisted device, and absorbs the material by matching the shape of the material through a special L-shaped suction nozzle. The suction nozzle is also provided with a rotating motor for rotating the patch surface. Through the auxiliary judgment of the camera, the direction of the patch is rotated and changed so that the entire patch meets the absorption requirements. When placing the material, an auxiliary inclined surface is also provided on the carrier belt to assist in placement, so that the conductive surface of the material can be placed on the carrier belt position, and the non-conductive surface is set vertically. With respect to the feeding of materials, the utility model can improve the feeding efficiency and feeding quality.
