Description

Technical Field

[0001] This utility model relates to the field of vacuum coating machine technology, and in particular to a limiting structure for a vacuum coating machine. Background Technology

[0002] A vacuum coating machine is a device that operates under high vacuum conditions. It is mainly used to deposit thin film materials on the surface of various substrates. Vacuum coating machines usually require a limiting structure to fix the substrate on the machine cover to ensure the stability of the coating process.

[0003] Current desktop evaporative vacuum coating machines typically have a circular placement tray under the machine cover, with four fixing clips installed on the tray. The substrate is fixed to the tray by locking the four fixing clips. However, since the positions of the four fixing clips are all fixed, it is difficult to effectively match substrates of various sizes. In addition, the fixing method of the clips will cover part of the substrate surface, thus affecting the integrity of the coating. At the same time, the placement tray is usually directly welded to the output shaft of the motor, making it inconvenient to disassemble and replace the limiting structure later. Therefore, a limiting structure that can be adjusted according to the size of the substrate and is easy to disassemble and replace is designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a limiting structure for a vacuum coating machine. This invention adjusts the positions of four arc-shaped limiting plates by adjusting four sliding components, allowing for adjustments based on the size of the substrate. Simultaneously, the snap-fit ​​seat above the limiting plate and the positioning seat below the machine cover can be quickly connected via positioning components, facilitating rapid disassembly and replacement of the limiting structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A limiting structure for a vacuum coating machine includes: a machine cover and a limiting plate. A positioning seat is connected to the bottom of the machine cover via a transmission rod. The positioning seat contains a positioning component, which includes two counter-moving convex locking blocks. A locking seat is integrally connected to the top of the limiting plate. The convex locking blocks are inserted into square locking grooves on both sides of the locking seat. The bottom of the limiting plate has four movable grooves distributed in a ring at equal intervals. Each movable groove is equipped with a sliding component, which includes a linearly moving first slider. An arc-shaped limiting plate is fixed below each first slider. The four arc-shaped limiting plates move towards the center to limit and fix the substrate.

[0007] The present invention is further configured such that a motor is fixedly installed on the top of the cover, and the output end of the motor passes through the cover and is connected to the transmission rod.

[0008] The present invention is further configured as follows: the positioning component includes: a bidirectional lead screw, which is rotatably connected inside the positioning seat; a second slider, which is slidably connected inside the positioning seat, and there are two second sliders, each threadedly connected to the outside of the bidirectional lead screw; and a second adjusting knob, which is rotatably connected to one side of the positioning seat and fixed to one end of the bidirectional lead screw.

[0009] The present invention is further configured such that the convex snap-fit ​​blocks are all fixed at the bottom of the second slider, and the convex snap-fit ​​blocks all abut against the inner wall of the snap-fit ​​seat.

[0010] The present invention is further configured such that the protruding parts of the convex snap-fit ​​block can be fitted into the square snap-fit ​​groove, and the square snap-fit ​​groove passes through both sides of the snap-fit ​​base.

[0011] The present invention is further configured as follows: the sliding assembly includes: a one-way lead screw, which is rotatably connected inside the movable groove; the first slider is threadedly connected to the outside of the one-way lead screw; and an adjustment knob, which is rotatably connected to the periphery of the limiting plate and fixed to one end of the one-way lead screw.

[0012] The present invention is further provided with a high-temperature resistant silicone pad on the surface of the arc-shaped limiting plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The limiting structure of this vacuum coating machine allows the substrate to be placed on the limiting plate. Then, by rotating the first adjustment knob, the first slider moves linearly, which in turn causes the arc-shaped limiting plate fixed to the first slider to move linearly. The four arc-shaped limiting plates move towards the center to clamp and fix the sides of the substrate. This method can be adjusted within a certain range according to the size of the substrate, and will not cover the surface of the substrate, thus ensuring the integrity of the coating.

[0015] 2. The limiting structure of this vacuum coating machine has a positioning seat under the machine cover and a concave snap-fit ​​seat above the limiting plate. By rotating the No. 2 adjustment knob, the two No. 2 sliders move in opposite directions, which in turn drives the two convex snap-fit ​​blocks to move in opposite directions. The two convex snap-fit ​​blocks fit into the square snap-fit ​​grooves on both sides of the snap-fit ​​seat, so that the snap-fit ​​seat and the positioning seat can be quickly connected, and the limiting plate can be quickly installed. At the same time, it is convenient for subsequent disassembly and replacement. Attached Figure Description

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0025] Reference Figure 1-4A limiting structure for a vacuum coating machine includes: a machine cover 1 and a limiting plate 2. A motor 9 is fixedly installed at the upper center of the machine cover 1. The output end of the motor 9 passes through the machine cover 1 and is fixedly connected to a transmission rod 10. A positioning seat 11 is integrally connected to the lower part of the transmission rod 10. The positioning seat 11 has a built-in positioning component. A snap-fit ​​seat 12 is connected to the upper part of the limiting plate 2. The positioning seat 11 and the snap-fit ​​seat 12 can be quickly docked through the positioning component.

[0026] For details, please refer to Figure 4 The positioning assembly includes a second adjustment knob 14, a bidirectional lead screw 15, and a second slider 16. The bidirectional lead screw 15 is rotatably connected to the inner side of the positioning seat 11. Two second sliders 16 are threadedly connected to the outside of the bidirectional lead screw 15. One end of the bidirectional lead screw 15 is fixed to the second adjustment knob 14.

[0027] In this embodiment, rotating the second adjustment knob 14 drives the bidirectional lead screw 15 to rotate, causing the two second sliders 16 outside the bidirectional lead screw 15 to move in opposite directions around the center of the bidirectional lead screw 15.

[0028] Furthermore, a convex snap-fit ​​block 13 is fixed below each of the second sliders 16.

[0029] Meanwhile, the card holder 12 is concave, and square card slots 17 are provided through both sides of the card holder 12.

[0030] In this embodiment, as Figure 1 As shown, two convex snap-fit ​​blocks 13 can be placed inside the snap-fit ​​seat 12. When the two second sliders 16 move in opposite directions, they can drive the two convex snap-fit ​​blocks 13 to move to both sides. Then, the protruding part of the convex snap-fit ​​block 13 is inserted into the square snap-fit ​​groove 17, thereby completing the quick docking of the positioning seat 11 and the snap-fit ​​seat 12.

[0031] This design allows for quick assembly and disassembly of the cover 1 and the limiting plate 2.

[0032] For details, please refer to Figure 2-3 The bottom of the limiting plate 2 has four movable grooves 3, which are arranged in a ring and are equidistant. Each of the four movable grooves 3 has a sliding component.

[0033] Specifically, the sliding assembly includes a one-way lead screw 4, an adjustment knob 5, and a slider 6. The one-way lead screw 4 is rotatably connected in the movable groove 3, the adjustment knob 5 is rotatably located around the limit plate 2, and the slider 6 is threadedly connected to the outside of the one-way lead screw 4.

[0034] In this embodiment, rotating the first adjustment knob 5 causes the one-way lead screw 4 to rotate, thereby causing the first slider 6, which is externally threaded to the one-way lead screw 4, to move linearly.

[0035] Furthermore, an arc-shaped limiting plate 7 is connected below the first slider 6, such as... Figure 2-3 As shown, the substrate can be placed on the surface of the limiting plate 2. The sides of the substrate can be clamped and fixed by adjusting the positions of the four arc-shaped limiting plates 7. The size of the substrate can be adjusted according to the size of the substrate without obstructing the substrate.

[0036] Meanwhile, a high-temperature resistant silicone pad 8 is provided on the surface of the arc-shaped limiting plate 7. The high-temperature resistant silicone pad 8 is in direct contact with the substrate and can provide elastic protection, reducing clamping wear on the substrate. The high-temperature resistant silicone pad 8 can be used in the furnace environment.

[0037] Working principle: When using this utility model, rotating the second adjustment knob 14 drives the bidirectional lead screw 15 to rotate, causing the two second sliders 16 outside the bidirectional lead screw 15 to move in opposite directions around the center of the bidirectional lead screw 15, placing the two convex locking blocks 13 inside the locking seat 12. When the two second sliders 16 move in opposite directions, they can drive the two convex locking blocks 13 to move to both sides, and then the protruding parts of the convex locking blocks 13 are inserted into the square locking grooves 17, thereby completing the quick docking of the positioning seat 11 and the locking seat 12, so that the machine cover 1 and the limiting plate 2 can be quickly disassembled and assembled. The substrate can be placed on the limiting plate 2, and then rotating the first adjustment knob 5 causes the first slider 6 to move linearly, thereby causing the arc-shaped limiting plate 7 fixed to the first slider 6 to move linearly, bringing the four arc-shaped limiting plates 7 together to the center to clamp and fix the side of the substrate. This method can be adjusted within a certain range according to the size of the substrate, and will not cover the surface of the substrate, ensuring the integrity of the coating.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
