Description

Technical Field

[0001] This utility model relates to the field of vacuum coating production technology, and in particular to a transmission and guiding structure for a vacuum coating carrier plate. Background Technology

[0002] In existing technologies, the carrier plate collides with the guide wheel during transmission to correct the direction of transmission. The positioning shaft that fixes the guide wheel is usually locked to the guide wheel fixing rod with a single nut. At the same time, the vacuum coating process is usually accompanied by a high temperature environment of over 150°C. In the high temperature environment, the metal material undergoes thermal expansion, which causes the locking nut to loosen and fall off during repeated collisions between the guide wheel and the carrier plate. This can lead to the guide wheel breaking or falling off, thus preventing the guide wheel from playing its role in direction correction. As a result, the carrier plate may get stuck or blocked during transmission. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a transmission and guiding structure for vacuum coating carrier plates to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a transmission and guiding structure for a vacuum coating carrier plate, comprising:

[0005] A fixing rod, one end of which is provided with a mounting groove;

[0006] The bearing is fitted inside the mounting slot;

[0007] A guide wheel, one end of which is provided with a positioning shaft, the positioning shaft being inserted into the inner ring of the bearing;

[0008] The bolt, one end of which passes through the guide wheel, positioning shaft and fixing rod, is equipped with a locking and anti-loosening component.

[0009] Preferably, it also includes a magnetic fluid, and the end of the fixing rod away from the mounting groove is detachably connected to the magnetic fluid.

[0010] Preferably, the magnetic fluid is provided with a slot, the fixing rod is inserted into the slot, the inner bottom of the slot is provided with at least two mounting holes, the fixing rod is provided with at least two locking waist holes, each of the locking waist holes is provided with an adjusting nut, and each adjusting nut cooperates with the mounting hole to lock the fixing rod onto the magnetic fluid.

[0011] Preferably, a retaining ring with a hole is installed between the guide wheel and the bearing.

[0012] Preferably, the locking and anti-detachment assembly includes:

[0013] A double-layer self-locking washer is provided on the side of the fixing rod away from the guide wheel, and the double-layer self-locking washer is sleeved on the bolt;

[0014] Two locking nuts are located on the side of the double-layer self-locking washer away from the fixing rod. The two locking nuts are stacked and fitted onto the bolt and threaded together.

[0015] The beneficial effects of this utility model are:

[0016] (1) The guide wheel is fixed to the fixed rod by bolts, which reduces the equipment manufacturing cost and makes replacement more convenient;

[0017] (2) By setting double-layer locking gaskets and two locking nuts, the interlocking effect of the two nuts prevents the locking nuts from falling off when the guide wheel collides repeatedly with the carrier plate, thus preventing the carrier plate from jamming or blocking.
