Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for vacuum coating machines, and relates to an auxiliary loading cart for a PVD vacuum coating machine. Background Art

[0002] The PVD vacuum coating process is a physical vapor reaction growth method. The atomic deposition process on the surface of the coated part is carried out in a vacuum or low-pressure gas discharge condition, that is, in a low-temperature plasma. The material source of the coating is a solid or gaseous substance. After "evaporation or sputtering", a new solid substance coating with completely different properties from the base material is formed on the surface of the part, improving the performance of the coated part.

[0003] Since the PVD coating process requires the coated part to rotate 360° in the chamber to deposit a uniformly covered film, the coated parts need to be arranged and suspended on a rotatable part rack. The weight of multiple groups of coated parts is relatively large, and an auxiliary loading cart is required to smoothly transport the part rack into the chamber.

[0004] Patent CN209481785U discloses a loading and unloading trolley for a rotatable rack of a vacuum coating machine. By installing a positioning device above the rack body, the rotatable rack of the vacuum coating machine is moved above the rack body and limited. The guide rail on the trolley is docked with the guide rail inside the coating machine cavity through the guiding and positioning device on the rack body, realizing the replacement of the rotatable rack of the coating machine in and out.

[0005] However, the chamber heights of different PVD vacuum coating machines are different. When the auxiliary loading cart equipped with the vacuum coating machine is damaged and cannot work, the coating work cannot be carried out due to the mismatch between the auxiliary loading cart and the chamber height, resulting in the inability to assist in loading. In the prior art, the height of the loading cart is usually increased by adjusting the screws at the bottom of the auxiliary loading cart, but the adjustment process is time-consuming and laborious, and it is extremely easy to cause the surface of the loading cart to be uneven, thus affecting the loading and greatly affecting the work efficiency and progress.

[0041] Working principle:

[0042] When the auxiliary loading cart is assisting in loading different PVD vacuum coating machine chambers, due to the different heights of the chambers of the PVD vacuum coating machine, it is necessary to adjust the height of the auxiliary loading cart. When adjusting the height, move the T-shaped sliders 507 of the two fixing plates 506 from the lower step of the step groove 105 to the upper step, so that the lifting mechanism 5 resumes rotation. Rotate the two lifting handles 501 to the horizontal position, pull out the arc-shaped pin 504, so that the upper frame 1 and the lower frame 2 resume sliding. By aligning the height fixing hole 103 with the height adjusting holes 202 at different heights, lift the upper frame 1 to the required height. Insert the arc-shaped pin 504 back into the corresponding height adjusting hole 202 and height fixing hole 103, and then move the T-shaped sliders 507 of the two fixing plates 506 from the upper step of the step groove 105 to the lower step to fix the lifting mechanism 5. The lifting mechanism 5 fixes the upper frame 1 and the lower frame 2, completing the height adjustment of the auxiliary loading cart.

[0043] When it is necessary to perform check limit on the material, rotate the turning handle 404 to the position corresponding to the limit block 406. At this time, the eccentric shaft 403 jacks up the check block 401, thereby performing check limit on the material. After the material limit is completed, slide the turning handle 404 so that the turning handle 404 is clamped between the limit blocks 406 to prevent the eccentric shaft 403 from rotating when the auxiliary loading cart moves, resulting in the check block 401 falling and unable to perform check limit on the material.
