Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for vacuum coating machines, in particular to an automatic feeding device for vacuum coating. Background Art

[0002] Vacuum coating refers to a method of heating metal or non-metallic materials under high vacuum conditions to evaporate and condense on the surface of the coated part to form a thin film. For example, vacuum aluminum coating, vacuum chromium coating, etc. In the coating process, a coating machine is needed.

[0003] At present, when the existing vacuum coating machine is used, it is necessary to prepare coating materials such as ceramic particles in advance, and then the staff can manually add them into the hopper of the coating machine. Since the addition process of the coating material is manually controlled, it cannot be guaranteed that the coating material can be added in a quantitative amount every time. Therefore, the staff needs to use tools such as measuring cups during the addition process. The whole addition process is rather cumbersome. For this reason, we propose a vacuum coating automatic feeding device to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an automatic feeding device for vacuum coating.

[0007] In this device, by providing a rotating shaft and a partition, when in use, the coating material can fall into the gap between the two groups of partitions for temporary storage. By starting the motor, the material inside the gap between the two groups of partitions can automatically fall into the interior of the vacuum coating machine, thereby completing the quantitative addition of the coating material.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 , an automatic feeding device for vacuum coating, including a vacuum coating machine 1, a feeding hopper 2 is connected to the top of the vacuum coating machine 1, and a motor 3 is installed on the back of the feeding hopper 2, the output end of the motor 3 extends to the inside of the feeding hopper 2 to connect to the rotating shaft 4, and the front of the rotating shaft 4 is connected to the inner wall of the feeding hopper 2 through a bearing, and the outer side of the rotating shaft 4 is equidistantly connected to the partition 5, the motor 3 is a prior art, and its speed can be adjusted automatically. In actual use, each time the motor 3 is started, a feeding operation is completed. In addition, the capacity of the ceramic particles between the partitions 5 is the amount required for the workpiece inside the vacuum coating machine 1, so that normal coating of the workpiece can be completed. A transparent observation window is provided on the front of the feeding hopper 2, which is not shown in the figure, so that the staff can check the feeding amount inside the feeding hopper 2.

[0025] Further, see Figure 3 and Figure 4 It can be known that the inside of the feeding hopper 2 is connected with a filter screen 6, and the filter screen 6 is located above the partition 5. When in use, the filter screen 6 can be set to block larger particles of ceramic particles to ensure the coating efficiency and coating quality.

[0026] Further, see Figure 3 and Figure 4 It can be known that an impact block 10 is arranged under the filter 6, and the impact block 10 is arranged as a cylindrical structure. When the partition 5 rotates, it will collide with the cylindrical impact block 10, so that the impact force can be transmitted to the filter 6 to make it resonate, thereby preventing the filter 6 from being blocked inside.

[0027] Further, see Figure 2 and Figure 4 It can be known that the front and back sides of the upper side of the filter 6 are symmetrically connected with extrusion plates 12, and the front and back positions of the feeding hopper 2 corresponding to the extrusion plates 12 are respectively installed with cylinders 11, and the ends of the cylinders 11 extend to the interior of the feeding hopper 2 and are connected to the extrusion plates 12. The cylinders 11 are prior art, and their specific telescopic principles are prior art, which will not be elaborated here. By setting two groups of cylinders 11, the extrusion and crushing of larger ceramic particles can be achieved.

[0028] Further, see Figure 5It can be known that a brush 13 is glued to the bottom end of the extrusion plate 12, and the lower side of the brush 13 is in contact with the filter 6. The brush 13 arranged below the extrusion plate 12 can clean the filter 6 while the extrusion plate 12 moves, so as to further prevent the filter 6 from being blocked.

[0029] Further, see Figure 3 It can be known that the upper side of the hopper 2 is symmetrically connected with a guide rod 14, and the interior of the extrusion plate 12 is provided with an insertion groove adapted to the guide rod 14. The guiding work of the extrusion plate 12 can be achieved through the mutual cooperation of the guide rod 14 and the insertion groove.

[0030] Further, see Figure 4 and Figure 5 It can be known that the lower side of the filter 6 is symmetrically connected with the socket rod 7, and the inside of the socket rod 7 is vertically connected with the buffer spring 8, the bottom end of the buffer spring 8 is connected with the insertion rod 9 through the linkage block 15, and the bottom end of the insertion rod 9 is connected through the impact block 10. When the partition 5 hits the impact block 10, the impact block 10 can push the insertion rod 9 to move inside the socket rod 7 under force. Combined with the buffer spring 8 arranged inside the socket rod 7, the impact force received by the buffer spring 8 can be buffered, thereby realizing the protection of the impact block 10.

[0031] Working principle: When the utility model is in use, the staff can first place the device at a suitable position, and then place the workpieces to be coated in turn inside the vacuum coating machine 1. After placing them, the staff can pour a certain amount of ceramic particles into the feeding hopper 2. After pouring, larger particles of ceramic particles can be retained above the filter 6, and then the staff can start the two groups of cylinders 11 to push the two groups of extrusion plates 12 towards each other to achieve the crushing of the ceramic particles. Then the ceramic particles can pass through the filter 6 and enter the gap between the two groups of partitions 5. Then the staff can start the motor 3 to drive the rotation of the shaft 4. At this time, the ceramic particles stored between the partitions 5 can fall into the interior of the vacuum coating machine 1. Since the spacing between the partitions 5 is the same, the quantitative falling of the ceramic particles can be achieved. The above is the entire working principle of the utility model.

[0032] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0033] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
