Abstract
Description
Technical Field
[0001] This utility model relates to the field of flipping machine technology, specifically to an anti-static flipping machine spacer. Background Technology
[0002] A flipping machine is a device used to automatically flip objects, commonly found in SMT production lines. It is mainly used to flip PCBs (printed circuit boards) 180 degrees to support double-sided processing or inspection. The working principle of the flipping machine is to use an electric motor or pneumatic device to push the object in the flipping direction, ensuring safety and efficiency in the flipping process.
[0003] During the production of PCB boards, static electricity is easily generated due to friction between the boards and external conveying equipment and the flipping structure in the flipping machine. This leads to static discharge during subsequent processing. Static discharge refers to the sudden release of static charge, which usually occurs when two objects come into contact or come into close proximity. It can damage electronic equipment. Therefore, static protection is particularly important in the production and use of electronic products. To address this, we propose an anti-static flipping machine spacer. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an anti-static flipping machine partition sleeve. This partition sleeve can effectively release the frictional static electricity generated during the conveying and flipping of PCB boards, avoid the electrostatic breakdown effect in the subsequent processing of PCB boards, and thus ensure the safety of PCB board production. It can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a partition for an anti-static flipping machine, including a fixed base, the fixed base being a cylindrical structure open at both ends, the outer ring surface of the fixed base having mounting grooves arranged in a circumferential array, and a conductive plate being fixedly connected inside the mounting grooves, the outer surface of the conductive plate having contacts fixedly connected in a linear array, the outer ring side of the fixed base being wrapped with insulating rubber, and the outer surface of the insulating rubber having through holes corresponding to the contacts set on the surface of the conductive plate, a support base being fixedly connected inside the fixed base, and a connecting seat corresponding to the external flipping shaft being fixedly connected inside the support base, and a ring-shaped limiting seat being fixedly connected inside the fixed base, and an overcurrent slip ring being slidably connected to the outer ring side of the limiting seat;
[0006] Specifically, the upper end of the inner ring of the slip ring is in contact with the end face of the conductive plate, and the output end of the slip ring is connected to the input end of the external ground wire.
[0007] Furthermore, the conductive plate is made of brass, and the contact surface of the conductive plate is electroplated with a nickel-based alloy wear-resistant coating, while the remaining parts of the conductive plate are sprayed with a silicon carbide anti-corrosion layer. The brass conductive plate can prevent charge accumulation, and the coating on the contact surface can effectively prevent wear of the conductive plate contacts. At the same time, the silicon carbide anti-corrosion layer can prevent the conductive plate from oxidizing and affecting its normal use, thus making the use of the spacer safer and more convenient.
[0008] Furthermore, the insulating rubber is KV insulating rubber, and both ends of the insulating rubber are rounded. A shock-absorbing layer is attached to the inner surface of the insulating rubber. The insulating rubber can effectively prevent the equipment from leaking electricity and causing damage to the PCB board, thereby making the use of the flipping machine safer.
[0009] Furthermore, the support base has a star-shaped structure and is made of elastic material, with reinforcing ribs embedded inside. The star-shaped support base can effectively distribute the force, and the elastic material can alleviate the pressure during flipping, preventing excessive squeezing force on the PCB board and thus making the flipping machine safer to use.
[0010] Furthermore, the surface of the connector is electroplated with a nickel-based alloy wear-resistant coating, and wedge-shaped grooves are respectively opened on the upper and lower sides of the inner ring surface of the connector to engage with the external insert; the wedge-shaped grooves can make the connector more stable and prevent the spacer from slipping and affecting its normal use.
[0011] Furthermore, the overcurrent slip ring is an empty round slip ring, meaning the slip ring is installed on a rotating shaft for use, and the output end of the overcurrent slip ring has a quick-connect structure; the quick-connect structure overcurrent slip ring is convenient to use, and the empty round slip ring has high stability, thus making the flipping machine more stable in use.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This antistatic flipping machine spacer has the following advantages:
[0013] 1. This spacer can effectively release the static electricity generated during the conveying and flipping of the PCB board, avoiding electrostatic breakdown during subsequent processing of the PCB board, thereby ensuring the safety of the PCB board production process.
[0014] 2. The star-shaped support base can effectively distribute the force, and the elastic material can relieve the pressure during the flipping process, avoiding excessive pressure on the PCB board and thus making the flipping machine safer to use.
[0015] 3. The wedge-shaped groove makes the connector more stable to install. At the same time, the brass conductive plate can avoid charge accumulation, and the plating on the contact surface can effectively prevent wear of the conductive plate contacts. In addition, the silicon carbide anti-corrosion layer can prevent the conductive plate from oxidizing and affecting its normal use, thus making the use of the spacer safer and more convenient.
