The invention provides an integrated circuit anti-reverse go-no go gauge which is internally provided with a rectangular slideway and a rectangular chute. A notch is formed in the right side of the rectangular sliding way and communicated with the left side of the rectangular sliding groove, and openings are formed in the left side and the right side of the rectangular sliding groove. The height of the rectangular slide way is larger than the thickness of the plastic package body, the height of the rectangular sliding groove is smaller than the thickness of the plastic package body, and the height of the rectangular sliding groove is larger than the thickness of the frame body. The rectangular slide way and the slide groove can be in multi-stage sleeving connection and are formed by matching and connecting the backer and the limiting rod. According to the invention, the reverse direction of the lead frame packaging structural member can be effectively prevented, and the defective rate is reduced; the transmission device is suitable for transmission of lead frame packaging structural members of various different specifications; and static electricity generated by the plastic package body can be eliminated, and a packaged chip is effectively protected.
This utility model discloses a vibrating screen device for battery cathode materials, comprising: a housing with a cavity inside suitable for accommodating materials, the housing also being provided with a screening assembly having a screening port communicating with the cavity; a vibration assembly adapted to drive at least a portion of the materials in the cavity through the screening port; and an antistatic assembly adapted to eliminate the charge carried by the materials in the cavity. The vibrating screen device for battery cathode materials designed according to this utility model includes an antistatic assembly, which can eliminate static electricity on the surface of the materials, thereby improving the screening efficiency of the vibrating screen device and the production capacity of cathode materials.
