[0011] In an optional embodiment, the boss abuts against two opposite side walls of the cavity so as to be suitable for dividing the cavity into a first cavity, a second cavity and a third cavity. The first cavity and the second cavity are respectively located on both sides of the boss, and the third cavity is located above the boss and communicates with the first cavity and the second cavity.

[0012] Beneficial effects: The boss divides the cavity into a first cavity, a second cavity, and a third cavity, so that the boss occupies a part of the volume of the cavity, thereby reducing the volume of liquid required for a single cleaning, which is beneficial to reducing liquid consumption and saving costs.

[0021] In an alternative embodiment, a liquid drainage mechanism is provided at the bottom of the cavity. The liquid drainage mechanism has a first state of preventing the liquid in the cavity from being discharged and a second state of allowing the liquid in the cavity to be discharged.

[0022] Beneficial effects: By means of the liquid drainage mechanism, the solution in the cavity is prevented from being discharged during the cleaning process, and the solution in the cavity is allowed to be discharged after a single cleaning is completed, so that there is no need to manually pour the solution into the cavity and empty the solution in the cavity, thereby reducing the possibility of the operator getting stained with the solution.

Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0037] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] Currently, during the use of the nozzle of APCVD, it needs to be cleaned and maintained every 24 hours of operation. In the industry, professional cleaning equipment is usually used for periodic and large-scale cleaning operations. Due to the high cost and large floor area of professional cleaning equipment, companies that do not specialize in device cleaning generally do not configure such equipment. Therefore, when professional cleaning equipment is not available, manual acid soaking cleaning is usually chosen, that is, the operator needs to manually prepare hydrofluoric acid with a concentration of 10% using a measuring cup, wear protective equipment, and manually soak and clean the nozzle in sequence. Hydrofluoric acid has extremely strong corrosiveness and strong permeability, which can damage both the skin and internal organs. Although professional protective equipment needs to be worn during manual acid soaking cleaning, safety accidents may still occur with a slight carelessness. This method is highly dangerous and has low efficiency.

[0039] The following will be combined with Figures 1 to 3, describe embodiments of the present utility model.

[0040] According to an embodiment of the present utility model, a cleaning device is provided, including:

[0041] A container 1, which has a cavity 10 inside. An opening communicating with the cavity 10 is provided at the top of the container 1. The cavity 10 is adapted to accommodate the workpiece to be cleaned 3.

[0042] At least one set of scale lines 8, which are arranged on the side wall of the cavity 10 and are spaced apart along the height direction.

[0043] A liquid injection pipeline 2, whose outlet end is located inside the cavity 10 and is fixedly connected to the inner wall of the cavity 10. The liquid injection pipeline 2 at least includes a first liquid injection pipeline 21 and a second liquid injection pipeline 22, so as to be adapted to inject different types of liquids into the cavity 10 respectively.

[0044] For the cleaning device provided in this embodiment, referring to the scale lines 8, different types of liquids are successively injected into the cavity 10 through the liquid injection pipeline 2 according to the volume ratio, so as to form a solution with the required concentration for cleaning the workpiece to be cleaned 3, thereby avoiding the operator accidentally getting contaminated by the corrosive and permeable liquid during the process of configuring a solution with a specific concentration using a measuring cup, and further improving the operation safety.

[0045] Specifically, the container 1 is in the shape of a box with an open top. The operator places the workpiece to be cleaned 3 into the cavity 10 of the container 1 through the opening. The scale lines 8 are horizontally arranged along the side wall of the cavity 10. Each set of scale lines 8 is composed of a shorter scale line 8, a medium-length scale line 8, and a longer scale line 8. As a feasible implementation form, according to the size and volume of the cavity 10, a shorter scale line 8 is set every 100 ml, a medium-length scale line 8 is set every 500 ml, and a longer scale line 8 is set every 1000 ml.

[0046] The liquid injection pipeline 2 includes multiple pipelines (such as 2 - 5 pipelines, two pipelines are adopted in this embodiment, for example: the first liquid injection pipeline 21 and the second liquid injection pipeline 22). The outlet ends of the multiple pipelines are located inside the cavity 10, and the inlet ends of the multiple pipelines respectively lead to multiple liquid storage containers storing different kinds of liquids. According to the required solution concentration, with the scale line 8 as a reference, in accordance with the volume ratio of different kinds of liquids, different kinds of liquids are successively injected into the cavity 10 through the multiple pipelines, thereby forming a solution with the required concentration, avoiding the operator accidentally getting stained with the liquid during the process of preparing the solution using a measuring cup, thus improving the safety of liquid preparation. And by setting at least one group of scale lines 8, it is beneficial for the operator to conveniently and quickly prepare a solution with the required concentration, thereby improving the efficiency of liquid preparation. Additionally, scale numbers are also provided on the side wall of the cavity 10 corresponding to the scale line 8. So that when the operator successively injects different kinds of liquids into the cavity 10 through the liquid injection pipeline 2, the volume of the injected liquid can be intuitively known through the scale numbers.

[0047] Taking the cleaning of the nozzle for APCVD as an example, the part to be cleaned 3 is configured as a nozzle. The nozzle needs to be placed in a 10% hydrofluoric acid solution for pickling cleaning. One of the first liquid injection pipeline 21 and the second liquid injection pipeline 22 is suitable for injecting pure water into the cavity 10, and the other is suitable for injecting hydrofluoric acid into the cavity 10. According to the volume ratio of hydrofluoric acid to pure water being 1:9, pure water and hydrofluoric acid are respectively injected into the cavity 10 through the liquid injection pipeline 2, thereby forming a hydrofluoric acid solution with the required concentration. Since hydrofluoric acid has extremely strong corrosiveness and strong permeability, which can not only damage the skin but also injure the internal organs, using the cleaning device of this embodiment can avoid the safety risks threatening the operator during the process of preparing the hydrofluoric acid solution using a measuring cup. And by injecting the hydrofluoric acid and water separately, after the pickling cleaning of the nozzle is completed and the solution in the cavity 10 is emptied, only pure water can be injected into the cavity 10, thereby completing the deacidification action of pure water after the hydrofluoric acid corrosion cleaning of the nozzle, which is beneficial to improving the cleaning efficiency.

[0048] In some embodiments, in combination with Figures 1 to 3 As shown, a boss 4 is provided at the bottom of the cavity 10, and the part to be cleaned 3 is placed on the boss 4 to be suitable for the boss 4 to support the part to be cleaned 3.

[0049] The cleaning device provided in this embodiment provides a placement support for the part to be cleaned 3 by providing a boss 4 inside the cavity 10.

[0050] Specifically, when the part to be cleaned 3 is placed on the convex platform 4, the highest point of the part to be cleaned 3 is lower than the liquid level in the cavity 10 during the cleaning operation, so that the part to be cleaned 3 can be immersed in the liquid in the cavity 10, thereby ensuring the cleaning effect of the part to be cleaned 3. The convex platform 4 is fixedly connected to the inner wall of the cavity 10. A groove 31 is formed on one side of the part to be cleaned 3 facing the convex platform 4. At least a part of the convex platform 4 is located in the groove 31 and abuts against the inner wall of the groove 31, so that the convex platform 4 forms a placement support for the part to be cleaned 3. Taking the nozzle of the APCVD equipment as an example, in combination with Figure 2 and Figure 3 As shown, the nozzle has a special appearance structure in the shape of a "concave" character with a groove 31 structure on one side. Therefore, a convex platform 4 in the shape of a "convex" block adapted to the "concave" character structure is provided at the bottom of the cavity 10, and the nozzle is buckled on the convex platform 4 through the groove 31, so that the convex platform 4 can provide a placement support for the nozzle.

[0051] In some embodiments, in combination with Figures 1 to 3 As shown, the convex platform 4 abuts against two opposite side walls of the cavity 10, so as to be suitable for dividing the cavity 10 into a first cavity 101, a second cavity 102 and a third cavity 103. The first cavity 101 and the second cavity 102 are respectively located on both sides of the convex platform 4, and the third cavity 103 is located above the convex platform 4 and communicates with the first cavity 101 and the second cavity 102.

[0052] For the cleaning device provided in this embodiment, the convex platform 4 divides the cavity 10 into a first cavity 101, a second cavity 102 and a third cavity 103, so that the convex platform 4 occupies a part of the volume of the cavity 10, thereby reducing the volume of liquid required for a single cleaning, which is beneficial to reducing liquid consumption and saving costs.

[0053] In some embodiments, in combination with Figures 1 to 3 As shown, a gap groove 7 is formed through the bottom of the convex platform 4, and the gap groove 7 is suitable for communicating the bottom of the first cavity 101 and the bottom of the second cavity 102.

[0054] For the cleaning device provided in this embodiment, by providing the gap groove 7 that communicates the bottoms of the first cavity 101 and the second cavity 102, it is convenient to ensure the liquid level balance between the first cavity 101 and the second cavity 102.

[0055] Specifically, the gap groove 7 is opened at the bottom of the convex platform 4 and penetrates the convex platform 4 along the direction from the first cavity 101 to the second cavity 102. Preferably, the bottom surface of the gap groove 7 coincides with the bottom wall surface of the cavity 10. The number of the gap grooves 7 includes at least one, and the gap groove 7 is suitable for communicating the bottom of the first cavity 101 and the bottom of the second cavity 102, thereby realizing the liquid level balance between the first cavity 101 and the second cavity 102 located on both sides of the convex platform 4.

[0056] In some embodiments, in combination with Figures 1 to 3 As shown, the direction in which the first cavity 101 faces the second cavity 102 is defined as the length direction of the cavity 10. When at least three parts to be cleaned 3 are placed side by side on the boss 4, along the length direction, the length of the cavity 10 is greater than or equal to the length of any one of the parts to be cleaned 3. The sum of the widths of the multiple parts to be cleaned 3 is S, and it satisfies:

[0057]

[0058] where k is the number of parts to be cleaned 3, and M k is the width of the k-th part to be cleaned 3. The width of the cavity 10 is S0, and it satisfies: S0 ≥ S.

[0059] For the cleaning device provided in this embodiment, by making the size of the cavity 10 satisfy that at least three parts to be cleaned 3 can be placed simultaneously, multiple parts to be cleaned 3 can be cleaned simultaneously, which is beneficial to improving the cleaning efficiency.

[0060] Specifically, since a single APCVD device has three nozzles, and each time of cleaning, all three nozzles need to be cleaned. Therefore, the cavity 10 is made to be able to accommodate at least three parts to be cleaned 3 to facilitate improving the cleaning efficiency.

[0061] In some embodiments, in combination with Figures 1 to 3 As shown, the cleaning device further includes a lifting frame 5. A partial area of the lifting frame 5 is adapted to abut against the side surface of the part to be cleaned 3 facing the boss 4, and a partial area is above the liquid level in the cavity 10, so as to be suitable for an operator to lift and shake the part to be cleaned 3 through the lifting frame 5.

[0062] For the cleaning device provided in this embodiment, the operator lifts and shakes the lifting frame 5 to drive the part to be cleaned 3 to shake in the solution, so as to perform a deeper cleaning on the part to be cleaned 3.

[0063] Preferably, the lifting frame 5 includes a rectangular frame 51 arranged in the horizontal direction. The rectangular frame 51 is located between the inner wall of the groove 31 of the part to be cleaned 3 and the upper surface of the boss 4. The lifting frame 5 further includes at least one lifting rod 52 extending in the vertical direction. The lower end of the lifting rod 52 is fixedly connected to the rectangular frame 51, and the upper end of the lifting rod 52 is above the liquid level in the cavity 10. The operator is suitable to lift and shake the rectangular frame 51 through the lifting rod 52, and further make the part to be cleaned 3 shake in the liquid, so as to perform a deeper cleaning on the part to be cleaned 3, improve the cleaning ability and efficiency. When it is not necessary to use the lifting frame 5 to lift and shake the part to be cleaned 3, the lifting frame 5 can be directly placed on the boss 4.

[0064] In some embodiments, in combination with Figures 1 to 3As shown, a liquid discharging mechanism is provided at the bottom of the cavity 10. The liquid discharging mechanism has a first state that prevents the liquid in the cavity 10 from being discharged, and a second state that allows the liquid in the cavity 10 to be discharged.

[0065] The cleaning device provided in this embodiment realizes preventing the solution in the cavity 10 from being discharged during the cleaning process through the liquid discharging mechanism, and allows the solution in the cavity 10 to be discharged after a single cleaning is completed. Thus, it is not necessary to manually pour the solution into the cavity 10 and empty the solution in the cavity 10 by pouring, thereby reducing the possibility of the operator getting contaminated by the solution.

[0066] Specifically, the liquid discharging mechanism is set to the first state to facilitate injecting different types of liquids into the cavity 10 through the liquid injection pipeline 2 to prepare the solution; after a single pickling cleaning of the workpiece 3 to be cleaned is completed, the liquid discharging mechanism is switched to the second state to discharge the solution in the cavity 10; the liquid discharging mechanism is switched to the first state again to inject only pure water into the cavity 10 through the liquid injection pipeline 2, thereby performing a pure water de-acidification operation on the workpiece 3 to be cleaned; after a single pure water de-acidification operation is completed, the liquid discharging mechanism is switched to the first state to discharge the liquid in the cavity 10. Through the cooperation of the liquid injection pipeline 2 and the liquid discharging mechanism, it is beneficial to greatly improve the working efficiency and eliminate all potential risks that may threaten the safety of the operator during the solution preparation process.

[0067] In some embodiments, as shown in Figures 1 to 3 the liquid discharging mechanism includes a liquid discharging hole 6 and a baffle 9. The liquid discharging hole 6 penetrates the bottom wall of the cavity 10. The baffle 9 is rotatably connected to the bottom wall of the cavity 10 and has a closed state that covers the liquid discharging hole 6 to prevent the liquid in the cavity 10 from being discharged, and an open state that exposes the liquid discharging hole 6 to allow the liquid in the cavity 10 to be discharged.

[0068] Specifically, the liquid discharging hole 6 is provided on the bottom wall of the cavity 10 and penetrates the bottom wall of the cavity 10 to be suitable for communicating the inside and outside of the cavity 10. As a preferred implementation form, a waste liquid bucket for storing waste liquid is further provided outside the cavity 10. The outlet of the liquid discharging hole 6 is connected to the waste liquid bucket through a conduit. After a single pickling cleaning or pure water de-acidification cleaning is completed, the baffle 9 is switched to the open state, so that the waste liquid in the container 1 flows to the waste liquid bucket through the liquid discharging hole 6 and the conduit, thereby preventing direct discharge and polluting the environment.

[0069] As a feasible implementation form, the baffle 9 is arranged on the inner surface of the bottom wall of the cavity 10. The rotation plane of the baffle 9 can be configured to be parallel to the inner surface of the bottom wall of the cavity 10. At this time, the baffle 9 forms a rotational connection with the inner surface of the bottom wall of the cavity 10 and always maintains surface contact; the rotation plane of the baffle 9 can also be perpendicular to the inner surface of the bottom wall of the cavity 10. At this time, the baffle 9 forms a hinge connection with the inner surface of the bottom wall of the cavity 10. As an additional implementation form, the baffle 9 is arranged on the outer surface of the bottom wall of the cavity 10. The rotation plane of the baffle 9 can be configured to be parallel to the outer surface of the bottom wall of the cavity 10. At this time, the baffle 9 forms a rotational connection with the outer surface of the bottom wall of the cavity 10 and always maintains surface contact; the rotation plane of the baffle 9 can also be perpendicular to the outer surface of the bottom wall of the cavity 10. At this time, the baffle 9 forms a hinge connection with the outer surface of the bottom wall of the cavity 10.

[0070] Additionally, the rotation axis of the baffle 9 and the bottom wall of the cavity 10 is connected to the output shaft of the drive motor. The drive motor is electrically connected to a controller disposed outside the container 1 and is controlled by the controller, so as to facilitate the operator to switch the baffle 9 between the closed state and the open state through the controller. It should be noted that the controller is electrically connected to the drive motor and controls the rotation or stop of the output shaft of the drive motor, as well as forward rotation or reverse rotation, which belongs to conventional technical means and will not be elaborated herein.

[0071] In some embodiments, as shown in Figures 1 to 3 a sealing gasket is fixedly connected to the side of the baffle 9 facing the bottom wall of the cavity 10. The sealing gasket is suitable for sealing the gap between the baffle 9 and the bottom wall of the cavity 10.

[0072] For the cleaning device provided in this embodiment, a sealing gasket is arranged between the baffle 9 and the bottom wall of the cavity 10 to seal the gap between the baffle 9 and the bottom wall of the cavity 10, thereby preventing the solution in the container 1 from leaking at the baffle 9.

[0073] Specifically, at least one layer of sealing gasket is arranged on the side of the baffle 9 facing the bottom wall of the cavity 10, so as to ensure the sealing effect between the baffle 9 and the bottom wall of the cavity 10, thereby preventing the liquid in the cavity 10 from leaking through the gap between the baffle 9 and the bottom wall of the cavity 10 when cleaning the workpiece 3 to be cleaned.

[0074] In some embodiments, as shown in Figures 1 to 3 the inner side surface of the bottom wall of the cavity 10 is arranged at an angle with the horizontal direction, and the drain hole 6 is located at the lowest position of the inner side surface of the bottom wall of the cavity 10.

[0075] For the cleaning device provided in this embodiment, by making the drain hole 6 located at the lowest position of the inner side surface of the bottom wall of the cavity 10, it is convenient for the liquid in the cavity 10 to be smoothly emptied under the action of gravity.

[0076] Specifically, the inner side of the bottom wall of the cavity 10 is arranged at an angle with the horizontal direction, so that the inner side of the bottom wall of the cavity 10 forms a lowest position at a certain location, and the liquid discharge hole 6 is arranged at this lowest position, so that the liquid in the cavity 10 is emptied under the action of gravity. As a feasible implementation form, the above-mentioned lowest position is located in the bottom wall area corresponding to the first cavity 101, the liquid injection pipeline 2 is located in the second cavity 102, one end opening of the gap groove 7 is correspondingly opened at the lowest position of the convex platform 4 facing the side wall of the first cavity 101, and the other end is correspondingly opened at the lowest position of the convex platform 4 facing the side wall of the second cavity 102, and the gap groove 7 extends in a straight line direction, so that the two ends of the gap groove 7 are opened in the bottom areas of the first cavity 101 and the second cavity 102, so as to effectively balance the liquid levels in the first cavity 101 and the second cavity 102, and prevent the liquid from remaining in the second cavity 102 or the gap groove 7 and being unable to be discharged.

[0077] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
