Description

Technical Field

[0055] The clamping device is moved, the second guide structure is activated, and the clamping device is controlled by the second guide structure to move along the second direction to move the watch glass to the first position.

[0056] Hot air is blown through the hot air duct, releasing gas with a humidity of less than 5% and a temperature of 80℃~90℃ into the glass casing. When the blowing time is t1, the hot air in the hot air duct is turned off.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0077] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0078] like Figures 1 to 6 As shown, some embodiments of the present invention provide a watch case glass cleaning machine, which is mainly used to clean the watch case glass to avoid damage to the watch case glass during the cleaning process and improve the cleaning quality and efficiency of the watch case glass surface.

[0079] The watch case glass cleaning machine includes a frame 100, a first guide structure 200, a second guide structure 300, a drive device 400, a clamping device 500, and a cleaning device 600. It should be noted that the drive device 400 is a drive motor, which drives the clamping device 500 to rotate.

[0080] Specifically, the cleaning device includes a hot air duct 610, a cold air duct 620, a vacuum head 630, and a connecting base 640. The hot air duct 610, the cold air duct 620, and the vacuum head 630 are all connected to the connecting base 640 to improve their stability on the connecting base 640. It is understood that the hot air duct 610 enables hot air cleaning of the watch case glass, the cold air duct 620 enables cold air cleaning of the watch case glass, and the vacuum head 630 enables vacuum cleaning of the watch case glass, thereby improving the cleaning quality and efficiency of the watch case glass.

[0081] It should be noted that the hot air duct 610 can be connected to a hot air generator. The hot air generator can adjust the temperature of the hot air to ensure that the humidity of the hot air blown out through the hot air duct 610 is less than 5%, the pressure is 0.1-0.5 MPa, and the temperature is 80-90°C. This allows moisture and some organic matter on the surface of the watch glass to evaporate quickly, while also blowing away dust and other inorganic matter from the watch glass. This not only prevents excessive temperature from affecting the watch glass but also improves the cleaning quality of the watch glass surface. It is understood that the blowing time during the hot air cleaning process of the watch glass through the hot air duct 610 can be set according to the actual situation.

[0082] In addition, the cold air duct 620 can be connected to a cold air generator. In this embodiment, the gas blown out of the cold air duct 620 is the gas formed after the sublimation of dry ice, and the watch glass is cleaned by the cold air through this gas. It should be noted that, since the residue on the watch glass after being cleaned by hot air drops rapidly from 80°C to 90°C to tens of degrees below zero, it will shrink and harden, causing the residue to loosen or detach directly. During the cleaning process through the cold air duct 620, the sweat stains and organic films remaining on the surface of the watch glass can harden, loosen or detach, thereby further improving the cleaning efficiency of the watch glass.

[0083] Furthermore, the vacuum head 630 can be connected to a vacuum pipe. Since the residual sweat stains and organic film on the surface of the watch glass have hardened and loosened after being treated by hot and cold air and have lost their stickiness, the vacuum suction force of the vacuum head 630 can adsorb the residual impurities on the watch glass onto the vacuum head 630, thereby further improving the cleaning quality of the watch glass surface.

[0084] In this embodiment, the first guide structure 200 is disposed on one side of the frame 100. Specifically, the first guide structure 200 is disposed on the top of the frame 100, and the output end of the first guide structure 200 is connected to the connecting seat 640 so as to drive the connecting seat 640 to move along the first direction through the first guide structure 200, thereby driving the cold air pipe 620, the hot air pipe 610 and the vacuum cleaner head 630 to move synchronously through the connecting seat 640.

[0085] It should be noted that the first direction refers to the direction perpendicular to the horizontal plane, that is, the vertical direction.

[0086] It is understandable that by adjusting the connecting seat 640 to move along the first direction, the distance between the cold air duct 620, the hot air duct 610, and the vacuum head 630 and the watch glass can be adjusted, thereby improving the cleaning efficiency and quality of the cleaning device 600 on the watch glass.

[0087] In addition, the clamping device 500 is connected to the output end of the second guide structure 300, and the clamping device 500 is driven to move in the second direction through the second guide structure 300, so that the clamping device 500 can be directly facing the cleaning device during the movement, so that the cleaning device can clean the watch case glass placed in the clamping device 500.

[0088] In this embodiment, the clamping device 500 can clamp and fix the watch case glass to improve the stability of the watch case glass in the clamping device 500.

[0089] It should be noted that the first direction is perpendicular to the second direction.

[0090] Furthermore, the output shaft of the drive device 400 is connected to the clamping device 500. Specifically, the drive device 400 is located on the side of the clamping device 500 opposite to the cleaning device 600, so that the clamping device 500 can be driven to rotate along an axis parallel to the first direction. This allows the cleaning device 600 to clean the watch case glass placed in the clamping device 500. By activating the drive device 400, the clamping device 500 rotates synchronously with the output shaft of the drive device 400, thereby causing the watch case glass to rotate synchronously. This ensures that the cleaning device 600 can evenly clean all areas of the watch case glass surface, avoiding blind spots and improving the cleaning quality and efficiency.

[0091] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the hot air duct 610 and the cold air duct 620 are respectively disposed on two opposite sides of the connecting seat 640, and the vacuum cleaner head 630 is disposed between the hot air duct 610 and the cold air duct 620.

[0092] Preferably, the inlets of the cold air duct 620 and the hot air duct 610 are symmetrically arranged on two opposite sides of the connecting seat 640, and the axis of the vacuum head 630 is parallel to the first direction. The inlets of the cold air duct 620 and the hot air duct 610 are both facing the axis of the vacuum head 630. This ensures that when the cleaning device 600 is facing the watch glass on the clamping device 500, the inlets of the cold air duct 620, the hot air duct 610, and the vacuum head 630 can be facing the watch glass, thereby improving the precision and quality of cleaning the watch glass.

[0093] It should be noted that, along the first direction, the inlets of the hot air pipe 610, the cold air pipe 620, and the vacuum head 630 all face the same end point. This allows the connecting seat 640 to effectively adjust the cleaning point position as it moves along the first direction, adapting to watch cases of different sizes, thereby improving the utilization rate of the cleaning device 600 and the cleaning range of the watch case.

[0094] Specifically, since the second guide mechanism can drive the clamping device 500 to move in the second direction, the inlets of the hot air pipe 610, the cold air pipe 620, and the vacuum cleaner head 630 all face the second guide mechanism. This allows the clamping device 500 to be directly aligned with the inlets of the hot air pipe 610, the cold air pipe 620, and the vacuum cleaner head 630 during its movement, thereby enabling the cleaning device 600 to clean the watch glass on the clamping device 500.

[0095] like Figure 1 and Figure 4 As shown, in some embodiments of the present invention, the first guide structure 200 includes a first drive motor 210 and a first slider 220. Specifically, along the first direction, the first drive motor 210 is disposed on the top of the frame 100.

[0096] The output end of the first drive motor 210 is connected to the first slider 220 so that the first drive motor 210 drives the first slider 220 to reciprocate along the first direction.

[0097] Meanwhile, the first slider 220 is connected to the connecting seat 640 through an elastic connector, so that the connecting seat 640 can rotate relative to the first slider 220. In addition, the elastic connector can keep the vacuum head 630 on the connecting seat 640 always in the first direction, so as to clean the relatively flat glass surface of the watch case.

[0098] Specifically, the elastic connector includes a spring 230 and a pivot pin 240. The connecting seat 640 is rotatably connected to the first slider 220 via the pivot pin 240. This allows the cleaning device 600 to be rotated relative to the first slider 220 by rotating the pivot pin 240. It should be noted that the pivot pin 240 and the first slider 220 can rotate relative to each other, so that the operator can rotate the pivot pin 240 to rotate the cleaning device 600 by a certain angle, thereby adjusting the cleaning angle of the cleaning device 600. This facilitates the cleaning of watch case glass with curved surfaces, meeting the requirements for cleaning the surfaces of watch case glass of different shapes, thereby improving the cleaning quality of different watch case glass.

[0099] In this embodiment, by placing the spring 230 between the first slider 220 and the connecting seat 640, it should be noted that the spring 230 is in a compressed state, so that the spring 230 always stores elastic potential energy. That is, the spring 230 has an elastic force on both the connecting seat 640 and the first slider 220. As the cleaning device 600 moves along the second direction, the elastic force of the spring 230 on the connecting seat 640 can keep the connecting seat 640 in a vertical state. That is, the inlets of the hot air pipe 610, the cold air pipe 620, and the vacuum head 630 can always remain vertically downward, thereby improving the stability of the cleaning device 600.

[0100] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the second guide structure 300 includes a second drive motor 310, a second slider (not shown in the figure), a support plate 330, a first guide rail 340, a second guide rail 350, and a third slider 360.

[0101] Specifically, along the first direction, the second drive motor 310 is located at the middle position of the frame 100, and the axis of the output shaft of the second drive motor 310 is perpendicular to the first direction.

[0102] The first guide rail 340 and the second guide rail 350 are arranged at intervals on the frame 100 and are both parallel to the second direction. Preferably, the first guide rail 340 and the second guide rail 350 are respectively arranged on two opposite sides of the axis of the output shaft of the first drive motor 210.

[0103] Simultaneously, the second slider is slidably connected to the first guide rail 340, and the third slider 360 is slidably connected to the second guide rail 350. Furthermore, to improve the stability and smoothness of the second slider during its sliding along the first guide rail 340, there are two first guide rails 340, both of which pass through the second slider, thereby limiting the movement of the second slider and preventing it from rotating.

[0104] In addition, the second drive motor 310 is disposed at one end of the first guide rail 340, and the output end of the second drive motor 310 is connected to the second slider, so as to drive the second slider to slide along the first guide rail 340 through the second drive motor 310.

[0105] Specifically, the second slider and the third slider 360 are connected by the support plate 330, so that as the second slider slides along the first guide rail 340, the support plate 330 drives the third slider 360 to slide synchronously along the second guide rail 350.

[0106] It should be noted that in this embodiment, the clamping device 500 is connected to the support plate 330, and the clamping device 500 is disposed on the side of the support plate 330 away from the first guide rail 340 and the second guide rail 350, so that the clamping device 500 can move synchronously in the second direction when the support plate 330 moves in the second direction.

[0107] In this embodiment, to prevent the third slider 360 from falling off the second slide rail, guide rail seats are installed at both ends of the second slide rail to limit the third slider 360.

[0108] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of the present invention, a limiting component 700 is provided on one side of the frame 100 so as to limit the movement of the clamping device 500 in the second direction.

[0109] Specifically, the limiting component 700 is disposed on the side of the second guide rail 350 away from the first guide rail 340, and at the same time, a blocking member 800 is provided on the side of the third slider 360 facing the limiting component 700, that is, the blocking member 800 can form a corresponding limiting structure with the limiting component 700.

[0110] It should be noted that the limiting component 700 is electrically connected to the second drive motor 310 so that when the limiting component 700 corresponds to the blocking member 800, the second drive motor 310 can be stopped, thereby achieving the limiting effect on the clamping device 500 during the movement process.

[0111] Specifically, the second drive motor 310 operates, driving the second slider to slide along the first guide rail 340. Simultaneously, the support plate 330 drives the third slider 360 to slide synchronously along the second guide rail 350. During the sliding of the third slider 360 along the second guide rail 350, when the blocking member 800 corresponds to the limiting component 700, the limiting component 700 can limit the blocking member 800 and stop the second drive motor 310, so that the third slider 360 stops at the first position or the second position.

[0112] In this embodiment, the first position is the cleaning position, and the second position is the loading / unloading position. As the name suggests, when the clamping device 500 moves to the first position along the second direction, the clamping device 500 is directly opposite the cleaning device 600, meaning that the watch case glass in the clamping device 500 can be cleaned by the cleaning device 600. When the clamping device 500 moves to the second position along the second direction, the clamping device 500 is away from the cleaning device 600, and the operator can remove the cleaned watch case glass from the clamping device 500.

[0113] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the limiting component 700 includes a first photoelectric sensor 710 and a second photoelectric sensor 720.

[0114] A photoelectric sensor is a device that converts light signals into electrical signals.

[0115] Along the second direction, there is a gap between the first photoelectric sensor 710 and the second photoelectric sensor 720, and both are electrically connected to the second drive motor 310. Specifically, as the third slider 360 slides along the second guide rail 350 towards the first photoelectric sensor 710, when the blocking member 800 moves to block the first photoelectric sensor 710, the first photoelectric sensor 710 is triggered and sends a control signal to the second drive motor 310 to stop the second drive motor 310, thereby stopping the clamping device 500 in the first position. Additionally, as the third slider 360 slides along the second guide rail 350 towards the second photoelectric sensor 720, when the blocking member 800 moves to block the second photoelectric sensor 720, the second photoelectric sensor 720 is triggered and sends a control signal to the second drive motor 310 to stop the second drive motor, thereby stopping the clamping device 500 in the second position.

[0116] Specifically, the output ends of the first photoelectric sensor 710 and the second photoelectric sensor 720 are oriented toward the second guide rail 350, so that when the third slider 360 slides along the second guide rail 350, the blocking member 800 can trigger the first photoelectric sensor 710 and the second photoelectric sensor 720, thereby stopping the second driving device 400 and causing the clamping device 500 to stop at the first position or the second position.

[0117] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the clamping device 500 includes a bidirectional cylinder 510, a pad 520, a fixing plate 540, and a support cylinder 550.

[0118] The bidirectional cylinder 510 is disposed on the side of the fixed plate 540 away from the driving device 400. The support cylinder 550 is sleeved on the bidirectional cylinder 510 and is spaced apart from the bidirectional cylinder 510. The pad 520 is disposed on the side of the support cylinder 550 away from the fixed plate 540 to provide support for the watch case glass. At the same time, the pad 520, the fixed plate 540 and the support cylinder 550 are connected and defined to form a receiving cavity. The bidirectional cylinder 510 is disposed in the receiving cavity to improve the simplicity of the appearance of the clamping device 500.

[0119] Specifically, a connecting block 560 is provided at each of the two output ends of the bidirectional cylinder 510, so that when the bidirectional cylinder 510 is started, the connecting block 560 can be driven to move synchronously in opposite directions through the two output ends. At the same time, a clamping block 570 is provided on each of the two opposite sides of the two connecting blocks 560, and the two clamping blocks 570 are arranged opposite each other to clamp the watch case glass.

[0120] Understandably, when the bidirectional cylinder 510 is activated, it drives the two clamping blocks 570 to move closer together, clamping the watch case glass placed on the pad 520. Once the watch case glass is clamped by the two clamping blocks 570, the bidirectional cylinder 510 stops operating, keeping the two clamping blocks 570 relatively stationary. This improves the stability of the watch case glass on the pad 520, facilitating cleaning by the cleaning device 600. After cleaning, the bidirectional cylinder 510 is activated, driving the two clamping blocks 570 away from each other, thus releasing the cleaned watch case glass so that the worker can remove it from the pad 520.

[0121] like Figure 2 and Figure 6 As shown, in some embodiments of the present invention, the clamping device 500 further includes a connecting platform 530, which is disposed on the side of the fixing plate 540 away from the bidirectional cylinder 510, so as to provide support and fixation for the clamping device 500 through the connecting platform 530, thereby improving the stability of the clamping device 500.

[0122] like Figure 2 As shown, in some embodiments of the present invention, a transmission assembly 900 is provided between the driving device 400 and the clamping device 500, so that the driving device 400 drives the clamping device 500 to rotate through the transmission assembly 900.

[0123] Specifically, the transmission assembly 900 includes a coupling 910, a bearing housing 920, a main shaft 930, a bearing 940, and a sealing seat 950. One end of the main shaft 930 is connected to the output shaft of the drive device 400 via the coupling 910. The axis of the main shaft 930, the axis of the coupling 910, and the axis of the output shaft of the drive device 400 coincide and are all parallel to the first direction, so that when the drive motor starts, the output shaft of the drive motor drives the main shaft 930 to rotate synchronously via the coupling 910.

[0124] The bearing seat 920 is disposed between the first guide rail 340 and the second guide rail 350. The bearing seat 920 is connected to the support plate 330 so that the support plate 330 can drive the bearing seat 920 to move synchronously when it moves along the second direction.

[0125] Meanwhile, the sealing seat 950 is positioned on the side of the bearing seat 920 away from the support plate 330, so that the bearing seat 920 can move synchronously with the support plate 330 as it moves along the second direction.

[0126] In this embodiment, the axis of the main shaft 930 coincides with the axis of the output shaft of the drive device 400, and both are parallel to the first direction.

[0127] In addition, the other end of the main shaft 930 is passed through the bearing seat 920 and the sealing seat 950 to connect with the connecting platform 530. It should be noted that the bearing seat 920 and the sealing seat 950 are rotatably connected to the main shaft 930, that is, the main shaft 930 can rotate relative to the sealing seat 950 and the bearing seat 920.

[0128] Specifically, the end of the spindle 930 furthest from the drive device 400 is inserted into the connecting platform 530. The spindle 930 is fixedly connected to the connecting platform 530 so that the spindle 930 can drive the connecting platform 530 to rotate during rotation, and the connecting platform 530 can drive the clamping device 500 to rotate synchronously, thereby causing the watch case glass placed in the clamping device 500 to rotate. In this embodiment, there is a gap between the connecting platform 530 and the sealing seat 950 to avoid friction between the connecting platform 530 and the sealing seat 950 during synchronous rotation with the spindle 930, thereby maintaining the stability and smoothness of the connecting platform 530 and the clamping device 500 during rotation.

[0129] like Figure 1 , Figure 2 and Figure 6As shown, in some embodiments of the present invention, the interior of the main shaft 930 defines a first airflow channel 931 and a second airflow channel 932 spaced apart, wherein the axis of the first airflow channel 931 and the axis of the second airflow channel 932 are both parallel to the axis of the main shaft 930, and the first airflow channel 931 and the second airflow channel 932 are symmetrically arranged on two opposite sides of the axis of the main shaft 930.

[0130] The first airflow channel 931 is connected to the first air port of the bidirectional cylinder 510, so that external gas can be connected to the first air port through the first airflow channel 931, and gas in the bidirectional cylinder 510 can be discharged from the first airflow channel 931 through the first air port. At the same time, the second airflow channel 932 is connected to the second air port of the bidirectional cylinder 510, so that external gas can be connected to the second air port through the second airflow channel 932, and gas in the bidirectional cylinder 510 can be discharged from the second airflow channel 932 through the second air port. This controls the movement of the output ends at both ends of the bidirectional cylinder 510, thereby controlling the clamping block 570 to clamp or release the watch case glass through the bidirectional cylinder 510.

[0131] In addition, a first annular groove 933 and a second annular groove 934 are provided at intervals on the side wall of the main shaft 930, and the axis of the first annular groove 933 and the axis of the second annular groove 934 both coincide with the axis of the main shaft 930.

[0132] Meanwhile, the first annular groove 933 is connected to the first airflow channel 931 through the first connecting hole. It can be understood that the first connecting hole is located on the side of the first annular groove 933 facing the first airflow channel 931, so as to connect the first annular groove 933 and the first airflow channel 931 through the first connecting hole.

[0133] In addition, the second annular groove 934 is connected to the second airflow channel 932 through the second connecting hole. It can be understood that the second connecting hole is located on the side of the second annular groove 934 facing the second airflow channel 932, so as to connect the second annular groove 934 and the second airflow channel 932 through the second connecting hole.

[0134] Furthermore, a first air pipe connector 1000 and a second air pipe connector 1100 spaced apart are provided on the side wall of the sealing seat 950. The first air pipe connector 1000 passes through the sealing seat 950 and communicates with the first annular groove 933, and there is a gap between the first air pipe connector 1000 and the main shaft 930. At the same time, the second air pipe connector 1100 passes through the sealing seat 950 and communicates with the second annular groove 934, and there is a gap between the second air pipe connector 1100 and the main shaft 930, so as to avoid friction between the main shaft 930 and the first air pipe connector 1000 and the second air pipe connector 1100 during the rotation, thereby enabling the main shaft 930 to maintain smooth rotation.

[0135] This allows the first air pipe connector 1000 to connect with the first airflow channel 931 through the first annular groove 933 and the first connecting hole during the rotation of the main shaft 930, and the second air pipe connector 1100 to connect with the second airflow channel 932 through the second annular groove 934 and the second connecting hole. That is, during the synchronous rotation of the clamping device 500 and the connecting platform 530 with the main shaft 930, external gas can be kept in communication with the bidirectional cylinder 510 through the first air pipe connector 1000 and the second air pipe connector 1100. This enables the bidirectional cylinder 510 to control the clamping block 570 to maintain a stable clamping state on the watch case glass, thereby improving the stability and cleaning quality of the watch case glass during the cleaning process.

[0136] like Figure 2 and Figure 6 As shown, in some embodiments of the present invention, a plurality of spaced-apart sealing rings 1200 are provided between the sealing seat 950 and the main shaft 930. It can be understood that the number of sealing rings 1200 can be two or more arbitrary numbers.

[0137] In this embodiment, there are three sealing rings 1200. The first sealing ring 1200 is located on the side of the first annular groove 933 away from the second annular groove 934. The second sealing ring 1200 is located between the first annular groove 933 and the second annular groove 934. The third sealing ring 1200 is located on the side of the second annular groove 934 away from the first annular groove 933. Each sealing ring 1200 is embedded in the inner wall of the sealing seat 950 and abuts against the main shaft 930. This prevents gas in the first airflow channel 931 and the second airflow channel 932 from escaping from the gap between the main shaft 930 and the sealing seat 950 during the rotation of the main shaft 930, thereby improving the sealing quality of the sealing seat 950, improving the stability of the bidirectional cylinder 510 during operation, and thus improving the stability of clamping the watch case glass.

[0138] The sealing ring 1200 is spaced from the first annular groove 933, and the sealing ring 1200 is spaced from the second annular groove 934.

[0139] like Figure 2 and Figure 6 As shown, in some embodiments of the present invention, a third air pipe connector 1300 and a fourth air pipe connector 1400 are respectively provided on two opposite sides of the connecting platform 530. The third air pipe connector 1300 passes through the connecting platform 530 and communicates with the first airflow channel 931, so that external gas can enter the first airflow channel 931 through the third air pipe connector 1300, and gas in the first airflow channel 931 can also be discharged through the third air pipe connector 1300. At the same time, the second air pipe connector 1100 passes through the connecting platform 530 and communicates with the second airflow channel 932, so that external gas can enter the second airflow channel 932 through the fourth air pipe connector 1400, and gas in the second airflow channel 932 can also be discharged through the third air pipe connector 1300, thereby adjusting the distance between the output ends of the two ends of the bidirectional cylinder 510, thereby adjusting the tension of the clamping block 570 in clamping the watch case glass.

[0140] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments of the present invention, both the third air pipe connector 1300 and the fourth air pipe connector 1400 are fitted with sealing sleeves 1500. The sealing sleeves 1500 are embedded in the connecting platform 530 to improve the sealing quality between the third air pipe connector 1300 and the fourth air pipe structure and the connecting platform 530, so as to prevent the gas in the first airflow channel 931 and the second airflow channel 932 from escaping from the gap between the third air pipe connector 1300 and the fourth air pipe structure and the connecting seat 640.

[0141] In addition, a sealing ring 1600 is provided between the sealing sleeve 1500 and the main shaft 930. The sealing ring 1600 abuts against the inner walls of the main shaft 930 and the connecting platform 530 respectively, so as to improve the sealing quality between the third air pipe joint 1300 and the connecting platform 530, and at the same time, improve the sealing quality between the fourth air pipe joint 1400 and the connecting platform 530, thereby ensuring the stability of the bidirectional cylinder 510 during operation, and thus ensuring the stability of the watch glass between the two clamps 570.

[0142] like Figure 7 As shown, some embodiments of the present invention also provide a cleaning method, including the watch case glass cleaning machine described in any of the above embodiments, the cleaning method comprising the following steps:

[0143] Step S100: Loading and clamping. The watch case glass to be cleaned is passed through the clamping device 500 and clamped by the clamping device 500.

[0144] Specifically, the watch case glass is placed on the watch case glass pad 520, and the bidirectional cylinder 510 is activated. The clamping blocks 570 at both ends of the bidirectional cylinder 510 are brought closer to each other and clamp the watch case glass.

[0145] In step S200, the clamping device 500 is moved, the second guide structure 300 is activated, and the clamping device 500 is moved along the second direction by the second guide structure 300 to move the watch case glass to the first position. The first guide structure 200 is activated to control the cleaning device 600 to move along the first direction to the preset position.

[0146] Specifically, the second drive motor 310 is started, and the clamping device 500 and the watch glass are moved along the second direction towards the side closer to the cleaning device 600 via the support plate 330. When the watch glass moves to the first position, the blocking member 800 triggers the first photoelectric sensor 710 to send a signal and cause the second drive motor 310 to stop running. At this time, the first position is the cleaning position, and the watch glass is directly facing the vacuum head 630 in the cleaning device 600.

[0147] Then, the first drive motor 210 is started, and the first drive motor 210 drives the slider to move the cleaning device 600 along the first direction toward the direction close to the glass of the watch case to the preset position, and then the first drive motor 210 stops running.

[0148] Step S300: Hot air purging. The hot air in the hot air pipe 610 is turned on to release gas with a humidity of less than 5% and a temperature of 80℃~90℃ into the glass of the watch case. When the purging time is t1, the hot air in the hot air pipe 610 is turned off.

[0149] Specifically, the hot air pipe 610 is connected to a hot air generator to blow hot air onto the watch case glass. The pressure of the hot air is 0.1–0.5 MPa. It should be noted that during the hot air blowing process on the watch case glass, the drive device 400 is activated, which in turn drives the clamping device 500 to rotate, thereby rotating the watch case glass. This improves the cleaning efficiency and quality of the watch case glass surface and avoids localized temperature differences.

[0150] The value of time t1 can be set according to the actual situation.

[0151] Step S400: Cold air blowing and rinsing. The cold air in the cold air pipe 620 is turned on to release dry ice gas into the glass of the watch case. When the rinsing time is t2, the cold air in the cold air pipe 620 is turned off.

[0152] It should be noted that dry ice can harden, loosen, or detach residual sweat stains and organic films, and can also remove debris from the watch case glass during the rinsing process. The value of time t2 can be set according to the specific circumstances.

[0153] In step S500, vacuum cleaning is performed. The vacuum in the vacuum head 630 is activated, and the cleaning device 600 moves towards the watch glass until the vacuum head 630 contacts the watch glass. The second guide structure 300 moves back and forth with the first position as the origin and the radius of the watch glass as the distance. At the same time, the drive device 400 is activated and the watch glass is rotated. When the cleaning time is t3, the second guide structure 300 drives the clamping device 500 back to the first position.

[0154] It should be noted that the wiping and vacuuming of the vacuum head 630 effectively removes dirt from the surface of the watch case glass. Specifically, the second drive motor 310 is activated, causing the clamping device 500 to reciprocate along the second direction by a distance equal to the radius of the watch case glass. Simultaneously, the drive device 400 is activated, causing the watch case glass to rotate along the axis of the main shaft 930. This not only saves energy consumption but also further improves the cleaning quality of the watch case glass surface.

[0155] The value of time t3 can be set according to the actual situation.

[0156] When the cleaning time reaches t3, the clamping device 500 is driven back to the first position by the second drive motor 310.

[0157] Step S600: Reset, cleaning device 600 moves up to the set position, vacuum in vacuum head 630 is turned off, drive device 400 stops running, second guide structure 300 drives clamping device 500 to move to the second position, clamping device 500 releases the watch case glass.

[0158] Specifically, the first drive motor 210 controls the cleaning device 600 to move along the first direction to the side away from the clamping device 500 to the set position, the vacuum head 630 is turned off, and the drive device 400 stops running, so as to avoid the glass of the watch case from rotating and save energy consumption.

[0159] The clamping device 500 is controlled by the second drive motor 310 to move away from the cleaning device 600 along the second direction. When the clamping device 500 moves to the second position, the blocking member 800 and the second photoelectric sensor 720 are triggered. The second photoelectric sensor 720 sends a signal to the second drive motor 310 to stop the second drive motor 310 so that the clamping device 500 remains stable in the second position.

[0160] Activate the bidirectional cylinder 510 and move the two clamps 570 away from each other, thereby releasing the watch case glass from the two clamps 570.

[0161] Step S700: Unload the watch case glass from the clamping device 500 to complete the cleaning of the watch case glass.

[0162] The cleaning of the watch case glass is completed by removing it from the pad 520.
