Description

Technical Field

[0001] The utility model relates to the field of tantalum oxide production, in particular to a tantalum oxide blank pressing device for coating. Background Art

[0002] Tantalum oxide is a commonly used high-refractive-index material with important applications in optical coatings. Tantalum oxide is a tantalum oxide with a high refractive index, high melting point, good chemical stability, and excellent electrical insulation properties. Its refractive index is typically around 2.1, making it an ideal material for high-refractive-index optical coatings. Its melting point is very high, around 1800°C, making it stable even in high-temperature environments. Tantalum oxide is also non-reactive with other chemicals, resulting in excellent corrosion resistance. In addition to its high refractive index, it also exhibits excellent optical transparency and UV resistance. The coating process begins with blank preparation, where tantalum oxide and other powders are selected, mixed and pressed into blocks according to a specific weight ratio, and then dried to form the blank. Currently, the batching and pressing process can only be performed individually, resulting in low manufacturing efficiency.

[0003] In summary, in order to solve the deficiencies in the prior art, it is necessary to design a tantalum oxide blank pressing device with a simple structure for coating. Utility Model Content

[0019] Below with reference to the embodiment and the attached Figures 1 to 4 , the technical solution of the utility model is further elaborated.

[0020] Example 1

[0021] A tantalum oxide blank pressing device for coating, comprising: a press platform 1, a pressing mechanism 2, a bottom plate 3, a push rod 4 and a drive assembly 5, wherein the press platform 1 is provided with a press material through hole 11 at intervals in the middle, and a powder material unloading area 12 is provided on both sides of the press platform, the bottom plate 3 is slidably arranged at the lower end of the press platform 1, the pressing mechanism 2 is arranged above the press platform 1, the pressing mechanism 2 includes a pressure head 21 matching the press material through hole 11, the push rod 4 is arranged at the upper end of the press platform 1, and the drive assembly 5 includes a bottom slide rail 51, a long slider 52, The short slider 53, the fixed block 54, the connecting rod 1 55, the connecting rod 2 56 and the motor 57, the long slider 52 is slidably set on the bottom slide rail 51, the short slider 53 is slidably set on the long slider 52, the fixed block 54 is symmetrically fixed on the long slider 52 and is located on both sides of the short slider 53, the lower end of the pushing rod 4 is connected to the long slider 52, the right side of the connecting rod 1 55 is rotated to connect the lower end of the short slider 53, the left end of the connecting rod 2 56 is rotated to connect the left end of the connecting rod 1 55, and the motor 57 is connected to the right end of the connecting rod 2 56.

[0022] like Figures 1 to 3 As shown, the working principle of the present invention is as follows: the motor 57 realizes the sliding of the short slider 53 on the long slider 52 through the connecting rod 1 55 and the connecting rod 2 56. When the push rod 4 moves from the right powder material discharge area 12 to the left, the powder is pushed into the press material through hole 11 until it moves to the left powder material discharge area 12. At this time, the state is as follows: Figure 1, the short slider 53 is located at the extreme left position on the long slider 52, the connecting rod 1 55 and the connecting rod 2 56 are in a parallel state, and then the connecting rod 2 56 continues to rotate counterclockwise under the drive of the motor 57, and the connecting rod 1 55 is pushed to the right to drive the short slider 53 to move right on the long slider 52. At this time, the long slider 52 does not move, and the push rod 4 also stops moving intermittently. At this time, the multiple pressing heads 21 move downward in this interval to press the powder in the pressing through hole 11 at one time until the short slider 53 hits the fixed block 54 on the right and The long slider 52 is driven to move right on the bottom slide rail 51, and the push rod 4 is driven to move right from the powder unloading area 12 on the left to carry out secondary unloading of the powder in the pressing through hole 11, until the push rod 4 stops in the gap in the powder unloading area 12 on the right, and multiple pressing heads 21 move downward in this interval to compress the powder in the pressing through hole 11 for the second time, and this cycle is repeated. After the powder in the pressing through hole 11 is intermittently pressed down multiple times until the blank of the specified thickness is formed, the bottom plate 3 slides open and unloads the material. The operation is simple and the pressing speed is fast.

[0023] As a further preferred embodiment, a base 6 is provided at the lower end of the bottom plate 3, and the bottom plate 3 is slidably disposed within the base 6. A cylinder 31 is provided at the side end of the bottom plate 3. When the pressing mechanism 2 is driven downward to press the pressing head 21 to press the powder in the pressing through hole 11, the bottom plate 3 can play a supporting role. When unloading is required, the cylinder 31 drives the bottom plate 3 to move out and open the pressing through hole 11.

[0024] As a further preferred embodiment, the array of the pressing through holes 11 is provided with nine groups, and the pressing mechanism 2 further includes a cylinder 22, the lower end of which is provided with a fixed connecting plate 23, and the pressing head 21 is fixed to the lower end of the fixed connecting plate 23. Nine blanks can be pressed at a time, further improving the pressing efficiency.

[0025] As a further preferred embodiment, guide surfaces 41 are provided on both sides of the upper end of the push rod 4. The guide surfaces 41 on both sides allow the push rod 4 to easily enter the tantalum oxide powder in the powder discharge area 12, so that more powder can be pushed when the powder is pushed in the reverse direction.

[0026] As a further preferred embodiment, baffles 13 are provided on both ends of the upper end of the press platform 1, and the baffles 13 are located outside the powder unloading area 12. The baffles 13 can prevent the tantalum oxide powder from falling.

[0027] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
