TECHNICAL FIELD

[0001] The utility model relates to MINI LED display product production equipment field, specifically a kind of cleaning device connected with magnetic coupling. BACKGROUND

[0002] In existing MINI LED cleaning equipment, the main rotating motor and the load shaft are usually directly connected by mechanical coupling. Such rigid connection has the following defects when running at high speed:

[0003] Vibration and noise: mechanical contact produces friction and impact, resulting in significant vibration and noise of the whole equipment, affecting the production environment and equipment life.

[0004] Sensitive to shaft deviation: low tolerance to axial, radial or angular deviation, prone to transmission failure due to installation error or thermal expansion.

[0005] High maintenance cost: contact type connection requires frequent lubrication and replacement of worn parts, increasing operation and maintenance cost.

[0006] Although magnetic transmission technology has been applied in some fields, it has not been optimized for the high-speed and high-precision requirements of MINI LED cleaning equipment. SUMMARY

[0007] To solve the above problems of the prior art, the utility model solves the technical problem by providing a cleaning device connected by magnetic coupling, to reduce vibration and noise of the equipment when rotating at high speed, and to realize stable production.

[0008] To solve the above technical problems, the utility model provides the following technical scheme:

[0012] A load turntable fixed to the end of the upper load shaft, used for placing MINI LED products to be cleaned;

[0013] A magnetic coupling B fixed to the end of the lower motor shaft;

[0014] A magnetic coupling A fixed to the end of the upper load shaft;

[0015] The magnetic coupling A and the magnetic coupling B are coaxially arranged in a non-contact mode and transmit rotating power through magnetic field coupling.

[0016] Preferably, the magnetic coupling A and the magnetic coupling B are permanent magnet structures.

[0017] Preferably, the axial distance between the motor lower rotating shaft and the load upper rotating shaft is 5.5 mm.

[0018] Preferably, the magnetic coupling A and the magnetic coupling B allow a certain axial, radial or angular deviation between the shafts.

[0019] Preferably, the cleaning device is used for MINI LED display product cleaning equipment after cutting.

[0020] Compared with the prior art, the cleaning device has the following beneficial effects:

[0021] The non-contact transmission reduces equipment vibration and noise, improves the production environment and equipment life, allows deviation between the shafts, adapts to installation errors and thermal expansion in automatic production, has compact structure, convenient installation, strong universality, and is suitable for MINI LED cleaning equipment.

[0027] As Figure 1 , Figure 2 ,

[0028] A cleaning device connected with a magnetic coupling, comprising:

[0029] Mechanism fixing base 1;

[0030] Motor 3 is installed on mechanism fixing base 1, and the output end of motor 3 is connected with motor lower rotating shaft 5.

[0031] Load rotating disc 2 is fixed at the end of load upper rotating shaft 4.

[0032] Magnetic coupling B7 is fixed at the end of motor lower rotating shaft 5.

[0033] Magnetic coupling A6 is fixed at the end of load upper rotating shaft 4.

[0034] The magnetic coupling A6 and the magnetic coupling B7 are coaxially opposite in a non-contact mode and transmit rotating power through magnetic field coupling.

[0035] The magnetic coupling A6 and the magnetic coupling B7 are permanent magnet structures.

[0036] The axial distance between the motor lower rotating shaft 5 and the load upper rotating shaft 4 is 5.5 mm.

[0037] The magnetic coupling A6 and the magnetic coupling B7 allow certain axial, radial or angular deviation between the shafts.

[0038] The cleaning device is used for cleaning MINI LED display products after cutting.

[0039] The motor 3 and the motor lower rotating shaft 5 are fixed on the mechanism fixing base 1. The magnetic coupling B7 is installed at the end of the motor lower rotating shaft 5. The load rotating disc 2 is connected to the magnetic coupling A6 through the load upper rotating shaft 4. The coaxiality of the magnetic coupling A6 and the magnetic coupling B7 is adjusted to ensure the non-contact magnetic coupling. The motor 3 is started to drive the load rotating disc 2 to rotate at high speed through magnetic transmission. Specifically, the motor 3 drives the motor lower rotating shaft 5 to rotate, which drives the magnetic coupling B7 to rotate. The magnetic coupling B7 drives the magnetic coupling A6 through magnetic field action, so that the load upper rotating shaft 4 and the load rotating disc 2 rotate at high speed synchronously. The load rotating disc 2 drives the MINI LED product to complete cleaning.
