Description

Technical Field

[0001] The utility model relates to the field of shielding plating steam, in particular to a baffle assembly applied to evaporation coating. Background Technique

[0002] The evaporation coating equipment is a device that gathers the steam coating on the workpiece to be coated. For example, the patent number is 201520375704.7, and the name is a new type of high-efficiency aluminizing equipment.

[0003] Considering that aluminum undergoes a process from solid state to gaseous state in the evaporation coating equipment, a transparent window is required to observe the aluminizing state inside the evaporation coating equipment through the window, so as to ensure that the process parameters can be adjusted in time when unexpected situations occur, and to ensure the production efficiency and product quality.

[0004] However, during aluminizing, the steam coating will be deposited on the entire evaporation area of the evaporation coating equipment. Therefore, this steam coating will also be deposited on the window glass, resulting in the visual image observed from the outside of the window becoming blurred or even invisible. In the case of a blurred or invisible visual image, it will affect the timeliness of parameter adjustment. Content of the Utility Model

[0005] To solve the above problems, the utility model provides a baffle assembly applied to evaporation coating. As a movable part, it can block the steam coating from gathering towards the window glass during the non-observation stage, ensuring that the image observed through the window is clear during use.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a baffle assembly applied to evaporation coating, which is arranged in the evaporation chamber of the evaporation coating equipment. The cavity in the evaporation chamber is closed by the baffle assembly to block the steam coating from gathering on the visual window in the cavity. Its characteristics are that the baffle assembly is located in the cavity, the baffle assembly includes a baffle that flips in the cavity, and a driving mechanism that drives the above-mentioned baffle to flip. After the baffle and the driving mechanism are in contact with the inner peripheral surface of the cavity all around, the steam coating is blocked from gathering on the visual window.

[0007] Furthermore, the driving mechanism is located on both sides inside the cavity. The baffle is connected to the driving mechanisms located on both sides inside the cavity. The baffle flips through the driving mechanism and abuts against a pair of inner surfaces of the cavity and the inner side surfaces of the driving mechanisms to block the steam coating from gathering into the cavity.

[0008] Further, the driving mechanism includes a second housing, and a driving cylinder, a rack, a gear and a coupling member located inside the second housing. The gear is arranged on the coupling member. The driving cylinder is connected to the connection area on the rack through a piston rod. The meshing surface provided on the rack meshes with the above-mentioned gear. The baffle connected to the coupling member flips in the cavity when the rack is driven by the driving cylinder to move reciprocally, so as to block the steam coating from gathering into the cavity. Among them, the baffle blocks the steam coating from gathering onto the viewing window by contacting the inner side surface of the second housing.

[0009] Further, it further includes a guide wheel, and the rolling surface of the guide wheel supports the rack.

[0010] Further, the coupling member is a rotating shaft, and the peripheral surface of the rotating shaft is connected to the baffle.

[0011] Further, it further includes a flash screen rotating roller and a rotating motor. The flash screen rotating roller is close to the baffle. The inside of the flash screen rotating roller is hollow, and a plurality of second openings are provided on its peripheral surface. The rotating motor drives the flash screen rotating roller to rotate.

[0012] Further, it further includes a transparent housing. The transparent housing is arranged in the evaporation chamber. The flash screen rotating roller is arranged in the transparent housing and is rotatably connected to the inner surface of the transparent housing.

[0013] Advantages of the present utility model:

[0014] The baffle assembly used in the present utility model can fit for use in the cavity in the evaporation chamber, play a sealing effect on the cavity, isolate the steam coating outside the cavity. During the non-observation stage, the baffle keeps the cavity in a normally closed state, so that the steam coating generated in the evaporation chamber cannot gather on the viewing window. Therefore, the viewing window under normal conditions can be kept free from being polluted by the steam coating, and the picture observed through the viewing window is clear.

[0023] Figure 1 This is a schematic view of a cavity formed on the outer shell.

[0024] The present utility model is a baffle assembly, which is arranged in the evaporation chamber of the evaporation equipment and is used to block the steam coating from gathering into the cavity 1a. The cavity 1a is formed by a part of the first outer shell 1 of the evaporation equipment protruding outward. The inner surface of the protruding part of the first outer shell 1 forms the above-mentioned cavity 1a. The outermost side surface of the protruding part of the first outer shell 1 is the viewing window 1b. The baffle assembly is located in the cavity 1a and includes a baffle 2 and a driving mechanism. The driving mechanism is located on both sides in the cavity 1a. The baffle 2 is connected to the driving mechanisms located on both sides inside the cavity 1a (as Figures 2 - 5 shown). The driving mechanism is the power source, and its output end is connected to the baffle 2 to drive the baffle 2 to make a flipping motion. The upper edge of the baffle 2 is in contact with the inner top surface of the cavity 1a. The baffle 2 has two states. One is that the lower edge 2a extending along the long direction of the upper edge of the baffle 2 is in contact with the inner bottom surface 1a' of the cavity 1a to block the steam coating from entering the cavity 1a. The other is that the lower edge 2a extending along the long direction of the upper edge of the baffle 2 is separated from the inner bottom surface 1a' of the cavity 1a for observing the aluminizing process inside the evaporation equipment.

[0025] It is not difficult to see that the closure of the cavity 1a is achieved by the combination of the driving mechanism and the baffle 2. The baffle 2 serves as a switch for observing the inside of the evaporation chamber. When blocking the steam coating from gathering into the cavity 1a, the baffle 2 is in contact with the inner side surface of the driving mechanism, the inner top surface and the inner bottom surface 1a' of the cavity 1a.

[0026] The driving mechanism includes a second outer shell 3. The baffle 2 is in contact with the inner side surface of the second outer shell 3 to block the steam coating.

[0027] This kind of driving mechanism located in the cavity has the following preferred methods:

[0028] It includes a driving part and a driven part 11. The driving part and the driven part 11 are independent and are respectively located on both sides inside the cavity 1a. The driving part includes a driving cylinder 4, a rack 5, a gear 6 and a connecting member 7. The gear 6 is arranged on the connecting member 7. The driving cylinder 4 is connected to the connection area 51 on the rack 5 through a piston rod. The meshing surface 52 provided on the rack 5 meshes with the above-mentioned gear 6. The baffle 2 connected to the connecting member 7 flips inside the cavity 1a when the rack 5 is driven by the driving cylinder 4 to reciprocate, so as to block the steam coating from gathering inside the cavity 1a.

[0029] The driven part 11 is for assisting the rotation of the connecting member 7. In the embodiment, one end of the connecting member 7 is connected to the above-mentioned gear 6, and the other end is connected to the rotating end of the driven part 11.

[0030] The driven part 11 is an existing driven rotating mechanism, so its structure will not be specifically elaborated here.

[0031] The driving mode of the gear 6 and the rack 5 has the characteristic of high precision. When closing the cavity 1a, the characteristic of high precision can ensure the airtightness of the cavity 1a after being closed. In addition, this meshing transmission structure has the advantage of small volume and can be applied in the small-space cavity 1a.

[0032] In the driving mechanism, a guide wheel 8 is also included. The rolling surface of the guide wheel 8 supports the rack 5. Specifically, the rolling surface supports the bottom surface of the rack 5. The guiding direction of the guide wheel 8 is the same as the direction of the reciprocating motion of the rack 5 in the driving cylinder 4. The purpose of using the guide wheel 8 is to replace sliding friction with rolling friction. In this way, the smoothness of the movement of the rack 5 can be improved and the wear of the rack 5 can be reduced.

[0033] The connecting member 7 is a rotating shaft, and the peripheral surface of the rotating shaft is connected to the baffle 2 and fixed by screws.

[0034] Such as Figures 6 - 8As shown, since the aluminum is heated by electricity in the evaporation chamber, the internal evaporation temperature is as high as 1300°. Therefore, there is strong light in the evaporation chamber, which cannot be seen directly by the naked eye. Therefore, the utility model also includes a transparent shell 9, a flash screen rotating roller 10 and a rotating motor 12 arranged in the evaporation chamber. The transparent shell 9 is arranged in the shell 1, and the flash screen rotating roller 10 is arranged in the transparent shell 9 and is rotatably connected to the inner surface of the transparent shell 9. The flash screen rotating roller 10 is close to the baffle 2. The flash screen rotating roller 10 is hollow inside and has a plurality of second openings 10a on its circumference. The rotating motor 12 drives the flash screen rotating roller 10 to rotate. The above scheme is designed based on the visual retention effect of the human body. The purpose of the flash screen rotating roller 10 and the second opening 10a is to highlight the switching back and forth between blocking the internal picture and displaying the internal picture. When the flash screen rotating roller 10 reaches a certain rotation speed, the naked eye can see the situation inside the evaporation chamber.

[0035] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
