Description

Equipment for rapidly counting chip scattered components

Technical Field

The utility model relates to an electron dress allies oneself with the field, in particular to an equipment that is used for scattered components and parts of piece formula to check fast.

Background

The counting and counting of components are the necessary steps before the production of materials, and especially for the outsourcing task, the complete and accurate preparation of the materials is a necessary guarantee for the effective implementation of the production. In combination with the actual production, the counting of the chip scattered devices is a bottleneck which seriously affects the efficiency of the production in the current electric fitting industry, especially for military electronic products, the used chip devices must be subjected to secondary screening by a specified mechanism, and all the chip devices originally packaged in a standard way are in a scattered state. In the aspect of storage, materials are packed randomly and are not orderly arranged, so that the number cannot be counted quickly and effectively in the warehousing process, manual repeated checking is required, manual waste is caused, and the warehousing accuracy cannot be guaranteed. In the aspect of production, all the sheet-shaped devices are subjected to quota material distribution in the production process of the electric device and are distributed by the single plates in a refined mode, and quantity counting errors often occur in the verification process due to the scattered material states, so that electric device personnel need to spend a large amount of time on verifying the quantity after finding more materials or less materials in the mounting process. In combination with the fact that the chip scattered device bodies are combined, the single chip of the chip device is light in weight and small in production quantity, and the using requirements of related braiders cannot be met in use, so that operations such as weighing, braiding counting, material sending and the like cannot be effectively implemented.

According to relevant data and research, although some inventions are created for counting and counting materials at present, the inventions are not suitable for bulk materials. Chinese utility model patent (CN 204191087U, an SMD point feeder): the material belt cutting device mainly utilizes a support, a material disc device, a driving counting device, a material disc guiding device and the like, ensures that an effective gap between a pressing roller and a driving wheel is beneficial to clamping of a material belt under the action of a linear sliding rail, and utilizes local convex teeth to position a material belt through hole so as to facilitate cutting, thereby realizing the functions of material counting and material belt cutting. Although the method avoids the problems of material counting and manual material shearing of the materials; however, the method is mainly used for counting and dividing the materials of the disk belt and cannot be used for counting and counting bulk material chip devices of on-board products. Chinese utility model patent (CN 205500395U, an intelligent material ordering and separating device): the device mainly utilizes an automatic mechanical mode to count, divide and seal and protect the coiled and belted materials; however, this design is still directed to the tape-winding method and cannot be applied to all bulk materials. Chinese utility model patent (CN 206991364U, an X-ray equipment for full-automatic electronic component material ordering) and chinese utility model patent (CN 205175934U, an X-ray equipment for electronic component material ordering): the device is checked by a conical penetrating X-ray emitted by an X-ray light pipe arranged in the device, and data is automatically stored. The method counts by using the non-contact mode of X-ray, and has the advantages of strong projection and accurate counting; but the method is still suitable for the disc belt material, and the X-ray has the harm of human radiation and large occupied area. Chinese utility model patent (CN 206411710U, a full-automatic quick material point equipment of SMD charging tray clout): the method mainly comprises the steps of utilizing an industrial camera to shoot to obtain specification information and size information of a material tray, obtaining data through image measurement and analysis, and counting the number of surplus materials of the material tray through calculation. The method utilizes the image recognition operation of an industrial camera to realize counting and automatic labeling in scientific research, but the method has larger constraint conditions for removing the material discs which do not accord with the counting, and simultaneously the method is not suitable for bulk material operation because the residual materials which are targeted at the material discs are counted.
