Description

Technical Field

[0001] The utility model relates to the field of vacuum coating machines, in particular to a coating liquid recovery device of a vacuum coating machine. Background Art

[0002] Vacuum coating refers to a method of heating metal or non-metallic materials under high vacuum conditions to evaporate and condense them on the surface of the coated object (metal, semiconductor or insulator) to form a thin film. There are many methods of vacuum coating, such as vacuum evaporation, cathode sputtering, chemical vapor deposition and ion plating.

[0003] During the vacuum coating process, a certain amount of coating liquid often remains inside the energy-saving vacuum coating machine. Therefore, a recovery device is installed at the bottom of the vacuum coating machine to collect and process the coating liquid. During the use of the vacuum coating machine, due to its constant opening and closing, a small amount of impurities are attached to the inner wall. To address this problem, the existing recovery device, when in use, mostly filters and recovers the coating liquid through the built-in filter net. The problems it has are:

[0004] First, during the recovery process, the coating liquid is directly collected and discharged through the collection structure, and then recovered through filtration. In the initial recovery step, it is difficult to spray and discharge the recovered coating liquid, which leads to the subsequent filtration step being prone to filter clogging. At the same time, in the subsequent filtration recovery step, the built-in filter needs to be manually disassembled to complete the cleaning, which makes it difficult to achieve quick cleaning operations, reducing the practicality of the recovery device.

[0005] Therefore, the utility model proposes a coating liquid recovery device for a vacuum coating machine. Utility Model Content

[0028] like Figure 3 As shown, the pump body assembly 7 includes a sleeve 12, a liquid pump body 11 and a delivery pipe 13 connected in sequence from top to bottom, the filter assembly 10 includes a fixedly connected mounting base 17 and a filter screen 18, and the filter assembly 10 is located directly above the recovery box 2 at the same time. The mounting base 17 is arranged in a trapezoidal shape as a whole, and two groups are arranged relatively to each other, which are arranged to fit the inner surface of the main bracket 1, and the inner surface of the main bracket 1 is provided with an "L"-shaped support platform corresponding to the mounting base 17. The filter screen 18 is arranged in a horizontal manner as a whole, and the mounting base 17 is used to facilitate the support and installation of the filter screen 18 on the inner side of the main bracket 1, and the filter screen 18 is used to filter the coating liquid sprayed and discharged after recovery.

[0029] like Figure 1-2 As shown, the recovery tray 4 is configured as a conical tray, the bottom end of which is centrally located and connected to the sleeve 12, a disc-shaped filter plate is embedded in the inner side of the recovery tray 4, the sealing ring 5 is configured as a rubber ring, which is sleeved on the outer side of the recovery tray 4, and the holder 6 is configured as an "L" shape and horizontally arranged, and its inner side is clamped with the outer side of the recovery tray 4, so that the recovery tray 4 with the built-in filter plate can filter the initially recovered coating liquid, and the sealing ring 5 can facilitate the recovery tray 4 to fit the external vacuum coating equipment to recover the coating liquid, and the holder 6 can support and limit the recovery tray 4.

[0030] The external coating liquid is first concentrated through the recovery tray 4, and the filter plate in the recovery tray 4 performs preliminary filtration and removal of impurity particles in the coating liquid. Then the coating liquid enters the pump body assembly 7 from the connection between the recovery tray 4 and the sleeve 12. When the recovery tray 4 is subsequently cleaned, the user can directly separate the recovery tray 4 and the card seat 6.

[0031] like Figure 3 As shown, the liquid pump body 11 is arranged vertically through the adjustment plate 8, and its bottom end is connected to the spray box 9 through the delivery pipe 13. The sleeve 12 is set as a rubber corrugated sleeve. The liquid pump body 11 cooperates with the sleeve 12 to achieve the effect of collecting the coating liquid recovered in the recovery tray 4, and the delivery pipe 13 is used to achieve the effect of delivering the coating liquid to the spray box 9. At the same time, the sleeve 12 is set as a rubber corrugated sleeve, which is convenient for adaptive extension adjustment according to the flipping degree of the adjustment plate 8.

[0032] The adjustment plate 8 and the spray box 9 are both horizontally arranged on the inner side of the main bracket 1. The two ends of the adjustment plate 8 are connected to the main bracket 1 through a shaft, and a driving motor is provided on the outside of one end of the adjustment plate 8. The spray box 9 is hollow and has multiple sets of adjustable nozzles on the inner bottom surface.

[0033] like Figure 4 As shown, the bristle layer 16 is evenly distributed in multiple groups along the bottom surface of the spray box 9, and is also evenly distributed between the multiple groups of mist nozzles inside the spray box 9. The adjustment plate 8 is used to drive the spray box 9 as a whole to flip and adjust inside the main bracket 1, and the spray box 9 is used to spray and guide the recovered coating liquid. The bristle layer 16 is used to dredge and clean the filter assembly 10, and at the same time, the sprayed coating liquid is assisted to be filtered.

[0034] like Figure 3 As shown, the guide rods 14 are distributed on both sides of the conveying pipe 13, the top of which is movable through the adjustment plate 8, and the bottom is fixedly connected to the surface of the spray box 9. Two groups of telescopic rods 15 are provided, which are located outside the guide rods 14. The telescopic rods 15 are fixedly connected to the adjustment plate 8 and the spray box 9 at the same time. The telescopic rods 15 are used to control the lifting and lowering of the spray box 9 as a whole on the inside of the main bracket 1, and the guide rods 14 are used to ensure the lifting stability of the spray box 9.

[0035] The initially recovered coating liquid is transported to the liquid pump body 11 through the sleeve 12, and the liquid pump body 11 transports it to the spray box 9 through the delivery pipe 13. The nozzle built into the spray box 9 divides the coating liquid into multiple beams and sprays them outward to contact the filter 18, so as to enhance the filtering treatment of the filter 18. The filtered coating liquid is recovered and concentrated in the recovery box 2. When the filter 18 needs to be cleaned, the user can directly remove the entire filter assembly 10 for cleaning, or drive the spray box 9 down by the telescopic rod 15 so that the brush layer 16 contacts the filter 18 to dredge its filter holes.

[0036] When the nozzle built into the spray box 9 divides the coating liquid into multiple beams and sprays them outward, the brush layer 16 can simultaneously filter and intercept a part of the impurity particles in the sprayed coating liquid, ensuring that the entire device effectively recovers the coating liquid. When it is necessary to clean the spray box 9 or the brush layer 16, the driving motor provided at the outer end of the adjustment plate 8 controls the adjustment plate 8 to flip, and then drives the spray box 9 to flip outward as a whole, so that the user can clean the nozzle built into the spray box 9 and the brush layer 16.

[0037] The working principle of the present utility model is as follows: when the device is in use, the pump body assembly 7 cooperates with the spray box 9 to enable the recovered coating liquid to be sprayed outward, and cooperates with the filter assembly 10 to achieve effective filtration processing. The filtered coating liquid is concentrated in the recovery box 2, and when the filter assembly 10 needs to be cleaned, the cleaning operation of the filter screen 18 can be completed by the spray box 9 that can be raised and lowered and adjusted in cooperation with the brush layer 16. When the spray box 9 and the brush layer 16 need to be cleaned and replaced, the adjustment plate 8 is flipped over so that the spray box 9 is flipped outward to facilitate the user to clean it.

[0038] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
