Description

Technical Field

[0001] The utility model belongs to the technical field of coating machines, in particular to a conveying mechanism of a vacuum coating machine. Background Art

[0002] Vacuum coating machine is a kind of equipment that uses vacuum technology for surface treatment, mainly used to form a thin film or coating on the surface of an object. Vacuum coating machine evaporates or sputters metal or compound materials in a vacuum environment, deposits them on the surface of the object to form a thin film or coating, thereby improving the surface performance, appearance or function of the object. Vacuum coating technology is widely used in various industries, such as optics, electronics, automobiles, medical, etc., to produce products with special functions or appearances, such as reflectors, anti-reflective coatings, anti-corrosion coatings, etc. The development and application of vacuum coating machines provide an important technical means to improve product quality and performance.

[0003] In the field of optoelectronics, evaporation coating machines are commonly used. Evaporation coating machines can achieve high-quality optical thin film coatings, such as anti-reflective coatings, anti-reflective coatings, reflective coatings, etc. By heating the solid coating material, evaporating it and depositing it on the lens surface, the optical transmittance can be increased, the reflection loss can be reduced, and the optical performance can be improved. Most of the existing vacuum coating machines are single-chamber structures, so a conveying mechanism is required to assist in loading and unloading. The existing coating machine conveying mechanism is prone to deviation and warping when conveying the jig carrying the material, which affects the loading and unloading speed and also affects the coating efficiency.

[0004] The patent with publication number CN215665771U discloses a horizontal conveying device for a vacuum coating machine that prevents deviation. The conveying plate is stabilized by setting a bearing group to prevent the conveying plate from deflecting. However, the bearing group of this design can only prevent the conveying plate from deflecting up and down, and it will still deflect in the left and right directions. At the same time, this design adopts a gear rack transmission method, and the gear rack is prone to vibration during operation, which makes the conveying plate prone to deflection.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example

[0027] A conveying mechanism of a vacuum coating machine, such as Figures 1 to 3 As shown, it includes a bottom plate 1, a positioning seat 12, a conveying plate 9 and a chain conveyor 2; the positioning seat 12 is fixedly connected to the bottom plate 1, the conveying plate 9 is connected to the positioning seat 12, the chain conveyor 2 is connected to the bottom plate 1 and the chain conveyor 2 is connected to the conveying plate 9;

[0028] A positioning slide rail 6 is also fixedly connected to the bottom plate 1, and a supporting positioning rod 7 is fixedly connected to one side of the conveying plate 9. The bottom of the supporting positioning rod 7 is rotatably connected to a positioning pulley 8, and the positioning pulley 8 is connected to the positioning slide rail 6 in cooperation; the positioning rod is used to support the conveying plate 9, and the cooperation between the positioning pulley 8 and the positioning slide rail 6 is used to ensure the stability of the conveying plate 9 during movement and prevent the conveying plate 9 from deflecting.

[0029] The positioning seat 12 is provided with a positioning groove 11, in which a first positioning roller group 10 is rotatably connected, and two rows of second positioning roller groups 18 are also rotatably connected on one side of the positioning seat 12 close to the conveying plate 9; the two rows of second roller groups and the first positioning roller group 10 constitute an activity space, and the side of the conveying plate 9 is arranged in the activity space, and the top surface and the bottom surface of the conveying plate 9 are respectively in contact with the second positioning roller group 18, and the side surface of the conveying plate 9 is in contact with the first positioning roller group 10. Among them, the activity space is used to limit the position of the conveying plate 9 to prevent the conveying plate 9 from being offset. At the same time, the design of the rollers can facilitate the movement of the conveying plate 9.

[0030] Specifically, when in use, the material to be coated is placed on the conveyor plate 9 through the coating jig, and the chain conveyor 2 is started, and the chain conveyor 2 drives the conveyor plate 9 to move. During the movement of the conveyor plate 9, the conveyor plate 9 needs to pass through the activity space. The first positioning roller group 10 on both sides will limit the conveyor plate 9 to prevent the conveyor plate 9 from deflecting on the horizontal plane. At the same time, the second positioning roller group 18 can clamp the conveyor plate 9, and during the movement of the conveyor plate 9, the conveyor plate 9 can be prevented from tilting to one side. Through the joint action of the first roller group and the second roller group, the position of the conveyor plate 9 can be effectively limited, and the conveyor plate 9 can be effectively prevented from being deflected or tilted, thereby ensuring the stability of the material on the conveyor plate 9. Since the activity space is composed of the first positioning roller group 10 and the second positioning roller group 18, the conveyor plate 9 is not easy to shake during the movement, thereby reducing the possibility of the conveyor plate 9 being deflected and improving the stability of the conveyor plate 9 during movement.

[0031] In addition, the power device adopted by the utility model is a chain conveyor 2, which has a compact structure and the advantage of smooth transmission, fundamentally guarantees the stability of the conveying plate 9 and can effectively prevent the conveying plate 9 from shaking or deflecting.

[0032] In a preferred embodiment, if Figures 1 to 3As shown, the cross section of the positioning seat 12 is an L-shaped structure, and a reinforcing rib 13 is provided at the corner of the positioning seat 12. The cross section of the positioning seat 12 is an L-shaped structure in order to ensure the stability of the positioning seat 12 while reducing the volume of the positioning seat 12. Since the volume of the positioning seat 12 is reduced, it is necessary to adaptively provide the reinforcing rib 13 to ensure the stability of the positioning seat 12.

[0033] In a preferred embodiment, if Figures 1 to 3 As shown, connecting parts 17 are provided on both sides of the conveying plate 9, and the connecting parts 17 are movably connected in the activity space. Specifically, the connecting parts 17 on both sides of the conveying plate 9 protrude outward and are located in the activity space. Through this design, the side wall of the conveying plate 9 is restricted by the second positioning roller group 18, thereby preventing the conveying plate 9 from deflecting.

[0034] In a preferred embodiment, if Figures 1 to 3 As shown, the chain conveyor 2 includes a mounting shell 3, a drive motor 4 and a conveying chain 5, wherein the mounting shell 3 is fixedly connected to the bottom plate 1, the conveying chain 5 is rotatably connected in the mounting shell 3, the drive motor 4 is fixedly connected to the mounting shell, a drive wheel is fixedly connected to the output shaft of the drive motor 4, and the drive motor 4 drives the conveying chain 5 to rotate via the drive wheel; a connecting seat is fixedly connected to the conveying chain 5, and the conveying chain 5 is connected to the conveying plate 9 via the connecting seat. It should be noted that the conveying plate 9 is located above the chain conveyor 2, and a connecting seat is fixedly connected to the chain of the chain conveyor 2, that is, Figure 1 The conveyor chains 5 of the chain conveyors 2 shown at the front and rear sides are each provided with a connecting seat. The conveyor plate 9 is fixedly connected to the connecting seat. The stroke of the chain conveyor is controlled to ensure that the connecting seat can only move on one side of the top of the conveyor chain 5. This design is to prevent the conveyor chain 5 from causing the connecting seat to flip, because the connecting seat will interfere with the conveyor plate 9 when flipping.

[0035] In a preferred embodiment, if Figure 2 As shown, the cross section of the positioning pulley 8 is a T-shaped structure. This structure enables the positioning pulley 8 to be stuck between the positioning slide rails 6, thereby ensuring the stability of the conveying plate 9 and preventing the conveying plate 9 from deflecting when moving.

[0036] In a preferred embodiment, the bottom plate 1 is also provided with an in-position auxiliary device, which includes a mounting frame 16 and a limiting roller 14; the two limiting rollers 14 are rotatably connected to the mounting frame 16, and a limiting space is formed between the two limiting rollers 14; a position block 15 is fixedly connected to the position on the support positioning rod 7 opposite to the limiting space. In order to prevent the conveying plate 9 from stopping suddenly after it is in position, so that the material on the conveying plate 9 moves due to inertia, a set of in-position auxiliary devices is designed to buffer and decelerate the conveying plate 9. When the conveying plate 9 is about to be in position, the in-position block 15 on the support positioning rod 7 enters the limiting space, and the in-position block 15 is gradually clamped by the limiting roller 14 to be decelerated. In addition, this design allows the conveying plate 9 to be restricted to a certain extent after it is in position, so that the conveying plate 9 will not move, thereby ensuring the stability of the conveying plate 9.

[0037] In a preferred embodiment, if Figure 3 As shown, the cross section of the positioning block 15 is a triangular structure. The limiting roller 14 can be gradually clamped to the positioning block 15 by setting and designing.

[0038] In a preferred embodiment, if Figure 4 As shown, the mounting frame 16 is provided with a mounting groove 23, and the two side walls in the mounting groove 23 are provided with a limiting groove 22, and the mounting groove 23 is slidably connected with an auxiliary block 21, and the two sides of the auxiliary block 21 are fixedly connected with the limiting blocks, and the limiting blocks are slidably connected in the limiting groove 22; the mounting groove 23 is also provided with a mounting spring 20, and the two ends of the mounting spring 20 are respectively connected with the auxiliary block 21 and the mounting frame 16; the two sides of the limiting roller 14 are fixedly connected with the mounting rod 19, and the limiting roller 14 is connected with the auxiliary block 21 through the mounting rod 19. Through this design, when the in-place block 15 contacts the limiting roller 14, the limiting rollers 14 on both sides will be squeezed to move, and when the limiting roller 14 moves, the mounting spring 20 will be compressed by the auxiliary block 21, thereby gradually increasing the force between the in-place block 15 and the in-place block 15, so that the in-place block 15 is gradually clamped, and slow deceleration is achieved.
