Description

Technical Field

[0001] The utility model relates to the technical field of coating machine workpiece disk installation, in particular to a mounting mechanism for an optical coating machine workpiece disk. Background Art

[0002] Depending on the type of workpiece to be coated, the workpiece fixtures used in optical coating machines also have a variety of different structural forms, including arched workpiece discs, rotary workpieces, and other types of fixtures.

[0003] Chinese Patent Publication No. CN213772213U proposes an installation mechanism for a workpiece tray of an optical coating machine. The utility model proposes the problem that "the existing workpiece tray needs to be lifted manually during the installation process, which greatly increases the workload and is very easy to be damaged by the workpiece tray", and proposes the following technical scheme: "Through the set cylinder, slide bar, second base, pulley, hydraulic cylinder, placement plate, rubber pad, connecting rod and protective cover, when in use, first place the workpiece tray on the placement plate, and then turn on the cylinder through the control switch. The cylinder drives the slide bar to move to the right, so that the second base moves to the right. When it moves to the installation position, the cylinder is closed again, and then the hydraulic cylinder is turned on. The hydraulic cylinder drives the placement plate to move upward, thereby lifting the workpiece tray, which is convenient for workers to install and greatly reduces the workload". However, in this technical scheme, there is a lack of a positioning method for the workpiece tray. In the process of the placement plate driving the workpiece tray to move upward, the workpiece tray is easily to fall off the placement plate due to vibration, which may cause damage to the workpiece tray or even hit the installer.

[0023] 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.

[0024] See also Figure 1-3 A mounting mechanism for a workpiece disk of an optical coating machine comprises a mounting block 1 and a cylinder 2 fixed on the upper surface of the mounting block 1, and an auxiliary structure for facilitating the installation of the workpiece disk is provided at the top end of the piston rod of the cylinder 2.

[0025] like Figure 1 As shown, the auxiliary structure includes a placing table 3 fixedly connected to the top of the piston rod of the cylinder 2, a bracket 4 respectively fixed to the left and right sides of the placing table 3, two support plates 5 fixed to the inner top wall of the bracket 4, a slide plate 6 slidably connected between the opposite sides of the two support plates 5, a slider 7 respectively fixed to the left and right sides of the slide plate 6, a driving component arranged on the upper surface of the slide plate 6, and a pressing component arranged at the bottom of the slide plate 6;

[0026] A displacement assembly is provided at the bottom of the mounting block 1 .

[0027] It should be noted that the driving assembly includes a threaded rod 8 rotatably connected to the upper surface of the slide plate 6, a threaded tube 9 threadedly connected to the outside of the threaded rod 8, and a twist cap 10 fixed to the top of the threaded rod 8. The upper surface of the bracket 4 is provided with a through hole compatible with the threaded tube 9, and the threaded tube 9 is fixed on the inner side of the through hole. The two support plates 5 are respectively fixed on the left side and the right side of the inner top wall of the corresponding bracket 4, and the right side wall of the support plate 5 on the left side of the inner top wall and the left side wall of the support plate 5 on the right side of the inner top wall are both provided with sliding grooves compatible with the slider 7.

[0028] The clamping assembly includes a telescopic rod 11 fixed to the bottom of the slide plate 6, a spring 12 arranged on the outside of the telescopic rod 11, and a clamping plate 13 fixed to the bottom end of the piston rod of the telescopic rod 11. The top end of the spring 12 is fixedly connected to the bottom of the slide plate 6, and the bottom end of the spring 12 is fixedly connected to the upper surface of the clamping plate 13. The clamping plate 13 corresponds to the placement table 3 up and down. The displacement assembly includes a base 14 attached to the bottom of the mounting block 1 and a sliding rod 15 fixed between the left inner wall and the right inner wall of the base 14. The sliding rod 15 is slidably connected to the inner side of the mounting block 1.

[0029] In addition, when the telescopic rod 11 and the spring 12 are used together, the elasticity of the spring 12 and the length adjustability of the telescopic rod 11 enable it to adapt to objects of various shapes and sizes, thereby improving the stability of the clamping. Specifically, when the shape of the clamped object is irregular or the size does not match the clamp, the elasticity of the spring 12 can make the clamping plate 13 better adapt to the shape and size of the object, and the length adjustability of the telescopic rod 11 can further adjust the clamping range of the clamping plate 13 to ensure the stability and reliability of the clamping. In addition, the use of the telescopic rod 11 and the spring 12 can also improve the rigidity and accuracy of the clamping. Since the telescopic rod 11 and the spring 12 usually have higher rigidity, they can provide a more stable clamping force to ensure the position accuracy and posture stability of the clamped object.

[0030] The working principle of the above embodiment is:

[0031] Place the workpiece disc on the placement table 3, then turn the twist cap 10 to drive the threaded rod 8 to rotate, and the threaded rod 8 then moves downward on the inner side of the threaded tube 9, and the threaded rod 8 then drives the slide plate 6 to move downward, and at the same time, the slide plate 6 passes through the slider 7 to make the downward movement process more stable, and then the slide plate 6 drives the telescopic rod 11 and the spring 12 to move downward, and the telescopic rod 11 then drives the clamping plate 13 to clamp the workpiece disc, and then start the cylinder 2 to drive the placement table 3 to move upward. Since the workpiece disc is clamped, the workpiece disc will not fall off the placement table 3 due to vibration during the rising process.

[0032] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
