Technical Field

The invention relates to the technical field of static electricity prevention, in particular to a grounding device for a rotating mechanism.

Background

In the electronics industry, component breakdown damage due to electrostatic breakdown is the most common and serious hazard in the electronics industry, particularly in the manufacture of electronic products. Electrostatic discharge may cause a hard or soft breakdown of the device. Hard breakdown is a permanent failure of a device, such as an open or short circuit between the output and input of the device, at one time. Soft breakdown can degrade the performance of the device and reduce its index parameters, causing potential failure. The soft breakdown can make the circuit good and bad (caused by the reduction of index parameters), and is not easy to be found, thus causing great troubles to the operation and fault finding of the whole machine. The equipment can still work with 'fault' during soft breakdown, the performance is not changed fundamentally, the equipment is likely to pass factory inspection, but the equipment can fail again at any time. Multiple soft punctures can cause hard punctures, so that equipment is not operated normally, thereby not only causing loss to users, but also influencing reputation of manufacturers and sales of products.

At present, the common anti-static method is to reliably ground the components and utilize the static protection monitoring system to perform static monitoring and protection. For a generally static component, static electricity is easily led out through a lead wire through a grounding body, but for a component needing to rotate, if the component needing to rotate and the grounding body are directly connected by using the lead wire, the lead wire can be wound and knotted, and the operation of the component needing to rotate and the service life of the lead wire are influenced.

Disclosure of Invention

The technical problem to be solved by the present invention is to provide a grounding device for a rotating mechanism, which can rapidly conduct away static electricity on the rotating mechanism, and simultaneously avoid winding and knotting of wires, so as to ensure normal operation of the rotating mechanism and no damage to the service life of the wires.

The technical scheme adopted for solving the technical problem is to provide a grounding device for a rotating mechanism, wherein the rotating mechanism is provided with a fixed part and a rotating shaft rotatably mounted on the fixed part, the grounding device comprises a conductive slip ring, a conducting wire and a grounding module, two ends of the conducting wire are respectively connected with the conductive slip ring and the grounding module, the conductive slip ring comprises a stator and a rotor rotatably mounted in the stator, the rotor is fixedly connected with the rotating shaft, and the stator is fixedly connected with the fixed part.

In the above technical solution, after the grounding device is installed on the rotating mechanism, the rotor of the conductive slip ring is fixedly connected to the rotating shaft of the rotating mechanism, so that the rotor can rotate along with the rotating shaft, and the stator of the conductive slip ring is connected to the fixing portion of the rotating mechanism, so that the stator can be in a stationary state relative to the fixing portion. Since the lead wire is connected to the stator, even if the rotating shaft is rotating, the lead wire is not twisted or knotted with the rotation.

As a first improvement of the grounding device of the present invention, the conductive slip ring is a via conductive slip ring. Through the improvement, the via hole conductive slip ring is mainly used for transmitting precise signals, weak current, large current and high voltage, and has the advantages of low torque, low loss, no maintenance, low electric noise and ultra-long service life, so that the overall performance of the grounding device is improved.

As a further improvement of the first improvement, the rotor includes an inner cylinder body with a through center and a pair of fixing members movably connected to a side wall of the inner cylinder body, the inner cylinder body is used for the rotation shaft to pass through, and the pair of fixing members is used for clamping the rotation shaft. Through the improvement, when the grounding device is installed on the rotating mechanism, the rotating shaft penetrates through the inner cylinder body, and the two fixing pieces clamp the rotating shaft together, so that the rotating shaft is stably connected with the stator, and the stator can rotate synchronously with the rotating shaft.

Furthermore, the fixing part is a screw, and the fixing part is in threaded connection with the side wall of the inner cylinder body, penetrates through the inner cylinder body from the outer side of the inner cylinder body and enters the inner side of the inner cylinder body. So, can realize through revolving soon the mounting the rotor with the fastening connection between the rotation axis has convenient operation's advantage.

As a second improvement of the grounding device of the present invention, the grounding device further includes a rotation stopping sheet, one end of the rotation stopping sheet is connected to the stator, and the other end of the rotation stopping sheet is used for being fixedly connected to the fixing portion. Through the improvement, when the grounding device is installed on the rotating mechanism, the other end of the rotation stopping sheet is fixedly connected with the fixing part, so that the fixing part and the stator are kept relatively static, and the conducting wire connected with the stator cannot be wound or knotted along with the rotation of the rotating shaft.

As a third improvement of the grounding device of the present invention, the grounding module is an electrostatic protection monitoring system. Through the improvement, the grounding device not only can rapidly guide away the static carried by the rotating mechanism through the grounding module, but also can comprehensively monitor the static condition of the rotating mechanism.

In summary, compared with the prior art, the grounding device for the rotating mechanism provided by the invention can achieve at least the following beneficial effects:

1. the grounding device can quickly conduct away static electricity on the rotating mechanism, and meanwhile, can avoid the winding, knotting and the like of the wires, and ensure the normal operation of the rotating mechanism and the service life of the wires not to be damaged;
