[0036] The full-automatic glasses cleaning machine and method have the following beneficial effects:

[0037] The controller monitors and promotes the operation of the cleaning device, the temperature control device and the air drying device in real time, realizes full automation of the cleaning process from one-key starting, directly puts the dirty glasses, and can wear clean and bright glasses after a little waiting.

[0038] The elastic pressure piece and support bracket, as key components of the fixed bracket, create a wide angle of view in the initial static state, allowing the operator to easily place the opened glasses onto the fixed bracket within the cleaning chamber using either two or one hand, and then activate the fully automatic glasses cleaning machine of the present invention. Once the fully automatic glasses cleaning machine begins operation, the elastic pressure piece of the fixed bracket rotates downward, flexibly securing the glasses and driving them to move. A warm cleaning solution is then used to clean the glasses in all directions, removing dust and dirt from the surface and ensuring a thorough cleaning of the lenses, particularly the temples that contact the ear canals.

[0039] After cleaning, the glasses enter fully automatic air drying, with a high-volume blower for rapid response. The air volume reaches its peak within 5 seconds, rapidly drying and removing any remaining water droplets from the glasses' surface, avoiding the discomfort of manual drying or the waste of paper towels. Each air outlet zone of the air knife outputs different airflow intensities, tailored to the airflow requirements of different parts of the glasses to be dried. Each outlet zone generates a downward-directed airflow that covers water droplets at different locations on the lens and temples, shifting the droplets downward, roughly in line with gravity. By increasing the airflow output of each outlet zone, the increased wind speed creates a strong thrust, preventing water droplets from flowing upwards. Larger droplets are accelerated downward along the lens surface, converging while smaller droplets are dried, resulting in faster drying and saving time. When the glasses are placed diagonally below the air knife, the airflow from the air knife outlet avoids obstruction by the frame, covering the entire surface of the glasses and accelerating drying.

[0040] The temperature control device controls the cleaning fluid to be in a temperature range of 21°C to 45°C, which is beneficial for cleaning dust and dirt, and avoids the risk of lens film cracking when the cleaning fluid temperature is higher than 50°C.

[0041] When the glasses are opened, they lie flat on the support bracket, with the nose bridge resting on the nose support of the support bracket, and the two temples resting on the temple supports, located below the elastic member. The elastic pressure member is driven by a transmission unit to control the rotation of the elastic pressure member. When the elastic pressure member rotates to the first position, people can quickly take and put the glasses. When the elastic pressure member rotates to the second position, it pushes the temples from top to bottom, achieving fast and flexible fixation of the glasses, avoiding wear and tear during cleaning, reducing manual operation, and improving the convenience and comfort of automated glasses cleaning. The three-point support and two-point elastic compression method can avoid damage to the glasses caused by sudden torque during single-point fixation. The two-point elastic compression ensures that the multiple support points between the glasses and the support bracket are evenly stressed, which can better stabilize the glasses and keep them stable under the influence of external forces during cleaning and drying.

[0042] The elastic pressing piece driving unit, the fixed support driving unit outside the humid environment and the fixed support inside the humid environment are connected by the connecting piece, the transmission unit is arranged inside the connecting piece, the electronic elements such as the driving unit are prevented from being affected by the humid environment during the glasses cleaning, and the operation safety and the service life of the device are improved.

DETAILED DESCRIPTION

[0051] The present application will be further described in detail below in combination with embodiments and with reference to the accompanying drawings.

[0052] An embodiment of the present application is a kind of full-automatic glasses cleaning machine, such as Figure 1 and Figure 2As shown, the device includes a cleaning chamber, a fixing support, a fixing support driving unit, a cleaning device, a drying device, and a controller.

[0053] The glasses are cleaned and dried in the cleaning chamber. The fixing support, located in the cleaning chamber, fixes the glasses. The fixing support driving unit, located outside the cleaning chamber, drives the fixing support to reciprocate or rotate upon receiving a moving instruction from the controller.

[0054] The fixing support includes a supporting support, an elastic pressing piece, a connecting piece, an elastic pressing piece driving unit, and a transmission unit, as shown. Figures 3 to 5 The supporting support includes a nose bridge support and a temple support. The nose bridge support is used to support the nose bridge of the glasses. The temple support is used to support the two temples of the glasses in an open state. The nose bridge support and the temple support support the glasses through three contact points (one nose bridge contact point and two temple contact points), forming a stable supporting structure. The elastic pressing piece and the supporting support are located inside the cleaning chamber and are connected to the cleaning chamber through the connecting piece.

[0055] The connecting piece is a hollow pipe that is closed to the outside to prevent water, cleaning liquid, or moisture from entering.

[0056] The elastic pressing piece driving unit is arranged outside the cleaning chamber, for example, on the top of the cleaning chamber, to avoid the humid cleaning environment. The elastic pressing piece driving unit is connected to the elastic pressing piece through the transmission unit and drives the elastic pressing piece to rotate around the rotation axis, switching the elastic pressing piece between the first position and the second position relative to the temple support. When the elastic pressing piece is in the first position, the elastic pressing piece is separated from the glasses on the supporting support, facilitating the taking and placing of the glasses. When the elastic pressing piece is in the second position, the elastic pressing piece presses against the temples of the glasses on the supporting support, achieving quick and flexible fixing of the glasses, avoiding wear caused by shaking of the glasses during cleaning, reducing manual operation, and improving the convenience and comfort of automatic cleaning of the glasses. Preferably, the driving unit is an electric motor.

[0057] The transmission unit is arranged inside the connecting piece and transmits the output of the elastic pressing piece driving unit to the elastic pressing piece, driving the elastic pressing piece to switch between the first position and the second position relative to the temple support. The output shaft of the transmission unit serves as the rotation axis of the elastic pressing piece.

[0058] Preferably, the transmission unit includes a worm and a worm wheel, and the worm wheel is engaged with the worm, as shown. Figure 5The connecting member comprises a horizontal hollow tube and a vertical hollow tube, which are perpendicular and internally connected. The worm gear is arranged in the horizontal hollow tube, and the worm shaft is arranged along the center line of the worm gear as the output shaft of the transmission unit, i.e., the rotating shaft of the elastic pressing member, which is sealed in the horizontal hollow tube, for example, the two sides of the worm gear are connected with the sealing covers, which play the roles of limiting and waterproofing. In this embodiment, the worm gear and the worm shaft are integrally formed. The worm is arranged in the vertical hollow tube, one end of the worm is connected with the output shaft of the driving unit, and the other end is engaged with the worm gear through the worm gear teeth. The vertical hollow tube is internally provided with a step, which plays the roles of supporting and axially limiting the worm. The worm is rotated under the driving of the driving unit, drives the worm gear to rotate around the worm shaft in the horizontal hollow tube, and thus drives the elastic pressing member to switch between the first position and the second position.

[0059] It can be understood that in the glasses fixing structure of the present application, the transmission unit can also be a sprocket and a chain arranged in the connecting member, or a gear and a rack arranged in the connecting member.

[0060] When the glasses are cleaned and air-dried, the fixing support reciprocally or rotationally moves under the driving of the fixing support driving unit, and the glasses supported thereon are cleaned and air-dried.

[0061] The cleaning device comprises a spray head arranged in the cleaning chamber. The cleaning liquid (generally in the form of a fan) sprayed through the spray head forms a cleaning area to flush the glasses. Preferably, at least two spray heads are arranged in the cleaning chamber, including a spray head higher than the glasses for spraying and washing the outer surface, top surface and side surface of the glasses, and a spray head lower than the glasses for spraying and washing the inner surface, bottom surface and side surface of the glasses. In another embodiment, the cleaning device further comprises a water tank, a water pump and a pipeline. The cleaning liquid stored in the water tank is pumped out by the water pump and then delivered to the spray head through the pipeline for spraying.

[0062] The air-drying device comprises an air blower and an air knife. The airflow is accelerated after entering the air blower and then blown out from the air knife to form an air-drying area to air-dry the glasses fixed on the fixing support.

[0063] In the present application, an air knife with a strong and weak air area design is adopted to be suitable for glasses. Specifically, as shown in Figure 6As shown, the air knife includes an air inlet part, a hollow air pipe and an air outlet part; one end of the air inlet part is connected to a fan placed outside the cleaning chamber, and the other end is communicated with one end of the hollow air pipe; the other end of the hollow air pipe is communicated with the air outlet part; the airflow output by the fan enters the hollow air pipe from the air inlet part, is guided by the air outlet part, and sends the airflow obliquely downward to the glasses; a plurality of guide plates are arranged in the air outlet part, forming air outlet areas with different airflow intensities, and the airflow output by each air outlet area is sent to different parts of the glasses. For example, the guide plates are four, and from top to bottom, they are a first guide plate, a second guide plate, a third guide plate and a fourth guide plate, forming five air outlet areas, which are a first air outlet area, a second air outlet area, a third air outlet area, a fourth air outlet area and a fifth air outlet area. Among them, the airflow output by the first air outlet area covers the upper edge of the frame of the glasses to be air dried, the airflow output by the second air outlet area covers the upper part of the surface of the glasses and the temples of the glasses, the airflow output by the third air outlet area covers the middle part of the glasses, the airflow output by the fourth air outlet area covers the lower part of the glasses or the lower edge of part of the glasses, and the airflow output by the fifth air outlet area covers the bottom edge of the glasses. According to the needs of different parts of the glasses to be air dried for the air drying airflow, the angles of the guide plates are adjusted, so that the air outlet part forms air outlet areas with different airflow intensities, and the airflow obliquely downward covers the water droplets at different positions on the surface of the glasses and the temples, so that the moving direction of the water droplets is generally consistent with the direction of gravity and moves downward. The enhanced air outlet area is provided, the airflow is accelerated to generate a strong thrust, so that the water droplets on the surface of the glasses do not flow upward, the larger water droplets move downward along the surface of the glasses, and the small water droplets are blown dry, the air drying speed is fast, and the air drying time is saved.

[0064] By placing the glasses obliquely below the air knife, the airflow at the outlet of the air knife can avoid the obstruction of the frame of the glasses, cover the surface of the glasses, and dry the glasses quickly.

[0065] The cleaning area and the air drying area are both located in the cleaning chamber. The cleaning chamber is provided with a liquid discharge port and an air discharge port, and the inner wall of the cleaning chamber is a smooth curve to facilitate the rapid flow of cleaning liquid and gas. The cleaning chamber is provided with a hatch, which is opened or closed according to the instructions of the controller, and the glasses can be put in or taken out through the hatch. During the cleaning and air drying process, the hatch is in a closed state, and after the cleaning is completed, the hatch is opened.

[0066] The controller controls the fixed support, the fixed support driving unit, the cleaning device and the air drying device to complete the cleaning step and the air drying step according to the set time or the number of rotations.

[0067] Preferably, the cleaning area and the air-drying area are at different positions in the cleaning chamber to avoid the influence of the humid environment after cleaning on the air-drying effect. At this time, in the cleaning step, the controller sends a moving fixed support instruction to the fixed support driving unit, the fixed support driving unit drives the fixed support to move to the cleaning area, and reciprocates or rotates in the cleaning area; the controller sends a cleaning instruction to the cleaning device, and the spray head sprays the cleaning liquid; after the cleaning step is completed according to the set time or rotation number, the controller sends a stop cleaning instruction to the cleaning device, and the spray head stops spraying the cleaning liquid. In the air-drying step, the controller sends a moving fixed support instruction to the fixed support driving unit, the fixed support driving unit drives the fixed support to carry the glasses to the air-drying area, and reciprocates or rotates in the air-drying area under the driving of the fixed support driving unit; the controller sends an air-drying instruction to the air-drying device, the air knife sprays air flow to the inner and outer surfaces of the glasses to blow off the water droplets on the surface of the glasses; after the air-drying step is completed according to the set time or rotation number, the controller sends a stop blowing instruction to the air-drying device, and the air knife stops blowing air.

[0068] The cleaning chamber is provided with a hatch, and the hatch is opened or closed according to the instruction of the controller.

[0069] The cleaning chamber is further provided with a hatch button, and the hatch button comprises an opening button; when the opening button is triggered, an opening signal is generated and sent to the controller, the controller sends an opening hatch instruction to the hatch, and the hatch is opened, so that the glasses can be put into or taken out of the hatch. The opening button can be a press trigger button or an induction trigger button, such as an induction trigger button arranged in a touch screen.

[0070] The hatch button further comprises a closing button; when the closing button is triggered, a closing signal is generated and sent to the controller, the controller sends a closing hatch instruction to the hatch, and the hatch is closed. The closing button can be a press trigger button or an induction trigger button, such as an induction trigger button arranged in a touch screen. The opening button and the closing button can be the same button.

[0071] Preferably, the full-automatic glasses cleaning machine of the application further comprises a temperature control device to stabilize the temperature of the cleaning liquid in a set temperature range. The lower the temperature of the cleaning liquid, the weaker the activity, and the worse the cleaning effect. However, if the temperature of the cleaning liquid is too high (for example, higher than 50℃), it will cause the risk of film cracking of the lens film layer. Preferably, the temperature of the glasses cleaning liquid is stabilized at 21℃ to 45℃, which is beneficial to cleaning dust and dirt, and avoids the risk of film cracking of the lens film layer due to too high temperature of the cleaning liquid. The temperature control device comprises a heating unit and a temperature controller, when the temperature controller detects that the temperature of the cleaning liquid reaches the lower limit of the temperature range (21℃), the heating unit is controlled to start heating, and when the upper limit of the temperature range (45℃) is reached, the heating unit stops heating.

[0072] As Figure 7As shown, the full-automatic glasses cleaning machine of the present application adopts the following full-automatic glasses cleaning method:

[0073] (Optional) Door opening step before cleaning:

[0074] Before starting cleaning, press the door opening button. After the controller receives the door opening signal, it sends an opening door instruction to the door to control the door to open. After the glasses are placed on the fixed support in the cleaning chamber, press the door closing button. After the controller receives the door closing signal, it starts the fixing step. Alternatively, after the door is opened for a set time or after detecting that the glasses have been placed on the fixed support (for example, by image detection processing), the controller sends a closing door instruction to the door to control the door to automatically close and start the fixing step.

[0075] Fixing step:

[0076] The controller sends a glasses fixing instruction to the elastic pressing part driving unit to fix the glasses placed on the support support on the support support.

[0077] Cleaning step:

[0078] The controller sends a fixed support moving instruction to the fixed support driving unit to drive the fixed support to move reciprocally or rotationally; the controller sends a cleaning instruction to the cleaning device to start the spray head to spray cleaning liquid to the inner and outer surfaces of the glasses, including the lens and the temple, to remove dust and dirt on the surface of the frame and the lens, and the sewage is collected or discharged at the bottom of the cleaning chamber; after the fixed support and the cleaning device complete the cleaning step according to the set cleaning time or rotation number, the controller sends a stop cleaning instruction to the cleaning device.

[0079] Air drying step:

[0080] The controller sends a fixed support moving instruction to the fixed support driving unit to drive the fixed support to move reciprocally or rotationally; the controller sends an air drying instruction to the air drying device, and the air knife sprays air flow to the inner and outer surfaces of the glasses to dry the water droplets on the surface of the glasses; after a set air drying time, the controller sends a stop blowing instruction to the air drying device, and the air knife stops blowing.

[0081] Separation step:

[0082] The controller sends a glasses separation instruction to the elastic pressing part driving unit to drive the elastic pressing part to separate from the glasses.

[0083] Preferably, when the cleaning area and the air drying area are at different positions in the cleaning chamber, the cleaning step further includes the fixed support driving unit driving the fixed support to move to the cleaning area carrying the glasses; the air drying step further includes the fixed support driving unit driving the fixed support to move to the air drying area carrying the glasses; and the separation step further includes the fixed support driving unit driving the fixed support to move to the initial position carrying the glasses.

[0084] (Optionally) after cleaning, open the door step:

[0085] After cleaning and drying, the controller sends an open door command to the door to control the door to open. After the glasses are taken out, the door is closed, and the controller receives the door closing signal to end. Alternatively, it can also end when the door is detected to be closed, for example, the controller receives the door closing signal from the sensor arranged on the door. Alternatively, after the glasses are taken out, the controller sends a close door command to the door to control the door to automatically close when it receives the door closing signal generated by pressing the door closing button, or after a set time, or when it detects that the glasses have been taken off the fixed support.

[0086] In this embodiment, the controller receives the signal generated by the user pressing the door opening button or the door closing button. Alternatively, the controller can also receive the signal from the door position sensor, temperature sensor, etc. in the fully automatic glasses cleaning machine, or the signal received from the input device such as a touch screen or a remote device such as a host computer. The controller transmits corresponding instructions to the cleaning device, temperature control device, and drying device respectively and receives feedback to realize human-computer interaction and intelligent control.

[0087] The fully automatic glasses cleaning machine, glasses cleaning device, and method of the present application control the operation of the cleaning device, temperature control device, and drying device in real time and promote the operation of the cleaning device, temperature control device, and drying device. From one-key start, the cleaning process is fully automatic, and dirty glasses can be directly put in and worn again after waiting for a while.

[0088] The elastic pressing piece and the supporting bracket, as important components of the fixed support, form a wide angle in the initial static state, so that the operator can easily put the glasses in the open state into the fixed support in the cleaning bin with both hands or one hand and start the fully automatic glasses cleaning machine of the present application. After the fully automatic glasses cleaning machine starts to work, the elastic pressing piece of the fixed support rotates downward to flexibly fix the glasses and moves the glasses to clean the glasses in all directions with the warm cleaning liquid to clean all parts of the glasses and remove the dust and dirt on the surface, so that the lens, especially the leg part between the ears, can be fully cleaned.

[0089] After cleaning, enter the full-automatic air-drying, large air volume fan can quickly respond. The air volume reaches the maximum peak area within 5 seconds, quickly blows and removes the residual water droplets on the surface of the glasses, avoids the discomfort of manual wiping or the waste of paper towel resources. According to the different parts of the glasses to be air-dried, the air flow output intensity of each air outlet area of the air knife is different, the air flow produced by each air outlet area covers the water droplets on the surface of the glasses and the glasses legs in different positions respectively, and the moving direction of the water droplets is basically consistent with the direction of gravity, moving downward.
