Description

Technical Field

[0001] This utility model belongs to the field of coated bandage technology, specifically relating to an adjustable coated bandage. Background Technology

[0002] A coating tensioner is a device used in vacuum coating processes for fixing and tensioning. It is primarily used to keep flexible or thin substrates (such as plastic films, metal foils, and glass sheets) in a flat and stable position during the coating process. This tensioner typically consists of a high-rigidity frame and an adjustable tensioning mechanism. It effectively prevents warping, wrinkling, or displacement of the substrate due to temperature changes or the vacuum environment, thereby ensuring uniform film thickness, strong adhesion, and excellent surface quality. It is an important tooling component for achieving high-precision thin film deposition.

[0003] Traditional coating tensioning frames use screws to lock the upper and lower clamps, and then adjust the tension of the diaphragm by rotating the adjusting ring. Because the upper and lower clamps use four hexagonal screws and are operated entirely by hand, the efficiency is extremely low. The adjusting ring protrudes from the lower clamp, so there is a risk of accidental activation after tension adjustment, which can lead to changes in the diaphragm tension and result in poor stability and reliability.

[0004] To address the aforementioned issues, this application proposes an adjustable coated tensioner. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides an adjustable coating clamping frame, which features fast and stable clamping.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable coating tensioner, comprising a lower clamp and an upper clamp, wherein a quick-clamping mechanism is provided between the lower clamp and the upper clamp, the quick-clamping mechanism comprising a U-shaped through groove opened on the side of the lower clamp, wherein a rotating long screw is provided in the U-shaped through groove, wherein a spring and a spring plate are sleeved on the outside of the long screw and are held in place by a nut, the quick-clamping mechanism comprising a first U-shaped groove and a second U-shaped groove opened on the side of the upper clamp, wherein the elasticity of the spring presses the spring plate into the first U-shaped groove, thereby pressing the lower clamp and the adjusting ring together.

[0007] As a preferred embodiment of this utility model, the width of the second U-shaped groove is greater than the diameter of the long screw and less than the outer diameter of the spring piece, and the width of the first U-shaped groove is less than the outer diameter of the spring piece.

[0008] As a preferred technical solution of this utility model, the quick clamping mechanism has several groups evenly distributed around the circumference.

[0009] As a preferred embodiment of this utility model, the opening of the first U-shaped groove is formed with a rounded corner.

[0010] As a preferred embodiment of this utility model, the outer side of the lower clamp has a plane perpendicular to the top surface.

[0011] As a preferred embodiment of this utility model, the lower clamp has an annular groove formed on its top, and the upper clamp has a positioning ring formed on its bottom that cooperates with the annular groove.

[0012] As a preferred embodiment of this utility model, the lower clamp is threadedly connected to an adjusting ring, the upper end of which is lower than the top surface of the lower clamp and the lower end is higher than the bottom surface of the lower clamp.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model replaces the traditional screw structure by using the cooperation between a long screw, nut, spring, and spring plate, saving screw tightening time and greatly improving production efficiency. Moreover, the thread structure of the long screw and nut can also adjust the clamping pressure and clamping position, which has significant flexibility.

[0015] This invention places the adjustment ring inside the lower clamp to prevent changes in diaphragm tension due to accidental contact, which could ultimately lead to product defects and improve product yield. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1 - Figure 4 The present invention provides the following technical solution: an adjustable coating tensioner, including a lower clamp 1 and an upper clamp 3, with a quick clamping mechanism between the lower clamp 1 and the upper clamp 3. The quick clamping mechanism includes a U-shaped through groove 11 opened on the side of the lower clamp 1, with a rotating long screw 4 in the U-shaped through groove 11. The U-shaped through groove 11 and the long screw 4 can be hinged by a pin, thereby realizing the rotation of the long screw 4 in the U-shaped through groove 11. A spring 6 and a spring piece 7 are sleeved on the outside of the long screw 4 and are held in place by a nut 5. The quick clamping mechanism includes a first U-shaped groove 31 and a second U-shaped groove 32 opened on the side of the upper clamp 3. The elasticity of the spring 6 presses the spring piece 7 into the first U-shaped groove 31, thereby pressing the lower clamp 1 and the adjusting ring 2 together.

[0025] Furthermore, the width of the second U-shaped groove 32 is greater than the diameter of the long screw 4 and less than the outer diameter of the spring piece 7, while the width of the first U-shaped groove 31 is less than the outer diameter of the spring piece 7, so that the long screw 4 can enter the second U-shaped groove 32 and ensure that the spring piece 7 can be stably pressed on the first U-shaped groove 31.

[0026] Furthermore, in order to ensure stable clamping of the lower clamp 1 and the upper clamp 3, the quick clamping mechanism is provided with several sets of clamps evenly distributed around the circumference.

[0027] Furthermore, such as Figure 2 As shown, the opening of the first U-shaped groove 31 has a rounded corner, and the outer side of the lower clamp 1 has a plane perpendicular to the top surface. Through the cooperation of the vertical plane and the rounded corner, even without moving the spring 7, the quick clamping mechanism can quickly clamp and release through the rotation of the long screw 4 and the elastic force of the spring 6.

[0028] Furthermore, in order to ensure accurate docking of the lower clamp 1 and the upper clamp 3, the lower clamp 1 is formed with an annular groove 12 at the top, and the upper clamp 3 is formed with a positioning ring 33 at the bottom to cooperate with the annular groove 12. By axially inserting the positioning ring 33 into the annular groove 12, the lower clamp 1 and the upper clamp 3 are radially limited.

[0029] Specifically, to avoid accidental activation caused by the protruding adjusting ring 2, an adjusting ring 2 is threadedly connected to the inner side of the lower clamp 1. The upper end of the adjusting ring 2 is lower than the top surface of the lower clamp 1, and the lower end is higher than the bottom surface of the lower clamp 1. This improves the stability of the adjusting ring 2 after adjustment inside the lower clamp 1, ensuring product yield.

[0030] The working principle and usage process of this utility model are as follows: Figure 2 The diagram shows the open state of the clamp. The diaphragm is placed in the adjusting ring 2, the upper clamp 3 is aligned with the lower clamp 1, and the positioning ring 33 engages with the ring groove 12 for positioning. Rotating the long screw 4 upwards compresses the spring 6, causing the spring piece 7 to slide along the outer wall of the lower clamp 1 into the first U-shaped groove 31. Under the action of the spring 6, the spring piece 7 is pressed firmly into the first U-shaped groove 31, resulting in the final clamping state. Figure 1 As shown.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
