Description

Technical Field

[0001] This disclosure relates to the field of cleaning machinery technology, and in particular to an automatic cleaning device and a fermentation device. Background Technology

[0002] In fermentation equipment, such as disc koji-making devices, production equipment such as loosening and discharging equipment are prone to material sticking. Throughout the production process, the sticky material gradually accumulates and may cause caking. Once the material caking on these production equipment, it will reduce the effect of loosening and discharging, thereby reducing production quality and efficiency.

[0003] To address these issues, currently, after a batch of products is produced, manual cleaning using handheld high-pressure water guns or high-pressure air guns is employed to blow away any adhering materials from the production equipment. However, this cleaning method is time-consuming, labor-intensive, and increases production costs. Furthermore, manual cleaning is inherently random and cannot guarantee that the blowing airflow will evenly and comprehensively cover the surface of the production equipment to be cleaned.

[0051] In the following description, the so-called first direction A corresponds to Figure 1 and Figure 2 The up and down directions, the second direction B corresponds to Figure 1 The left and right directions, the third direction C corresponds to Figure 2 The left and right directions.

[0052] like Figures 1 to 4 As shown, this disclosure provides an automatic cleaning device. The automatic cleaning device is used to spray a blowing airflow onto a device 100 to be cleaned, and includes a blowing device 2 and a driving device. The blowing device 2 includes an air outlet 2a, through which the blowing airflow flows to the device 100 to be cleaned. The driving device includes a first driving part and a second driving part that are independent of each other. The blowing device 2 is disposed on the first driving part. The first driving part is drivenly connected to the blowing device 2 and configured to drive the blowing device 2 to reciprocate relative to the first driving part along a first direction A. The first driving part is disposed on the second driving part. The second driving part is drivenly connected to the first driving part and configured to drive the first driving part to reciprocate relative to the second driving part along a second direction B perpendicular to the first direction A.

[0053] The automatic cleaning device provided in this disclosure includes a blowing device 2 and a driving device. The blowing airflow flows through the air outlet 2a of the blowing device 2 to the device 100 to be cleaned. The driving device includes a first driving part and a second driving part that are independent of each other. The blowing device 2 is disposed on the first driving part, and the first driving part is drivenly connected to the blowing device 2 to drive the blowing device 2 to reciprocate relative to the first driving part along a first direction A. The first driving part is disposed on the second driving part, and the second driving part is drivenly connected to the first driving part and configured to drive the first driving part to reciprocate relative to the second driving part along a second direction B perpendicular to the first direction A. Compared with manual cleaning, the automatic cleaning device's driving device drives the blowing device 2 to reciprocate along both the first direction A and the second direction B, which helps ensure that the blowing airflow evenly and comprehensively cleans all positions of the device 100 to be cleaned, ensuring effective cleaning. This automatic cleaning device facilitates automatic cleaning and improves cleaning efficiency.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, the first drive unit includes a first actuator 37, a first moving device 31, and a first transmission device 32. The purging device 2 is connected to the first moving device 31. The first actuator 37 is driven connected to the first transmission device 32 and configured to provide driving force to the first transmission device 32. The first transmission device 32 is driven connected to the first moving device 31 and configured to drive the first moving device 31 to reciprocate along a first direction A. The second drive unit includes a second actuator 38, a second moving device 33, and a second transmission device 34. The second moving device 33 is driven connected to the first drive unit. The second actuator 38 is driven connected to the second transmission device 34 and configured to provide driving force to the second transmission device 34. The second transmission device 34 is driven connected to the second moving device 33 and configured to drive the first drive unit to reciprocate along a second direction B by driving the second moving device 33 to reciprocate along a second direction B.

[0055] The first actuator 37 is driven and connected to the first transmission device 32, and the second actuator 38 is driven and connected to the second transmission device 34. This makes it easier to make the control of the movement of the blowing device 2 along the first direction A and along the second direction B independent and non-interfering with each other, which helps to improve the accuracy of the drive and allows the blowing device 2 to reach the position that needs to be cleaned more accurately, thereby improving the cleaning efficiency.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the first transmission device 32 and the second transmission device 34 include a transmission chain. In embodiments not shown, the first transmission device 32 and the second transmission device 34 may also include a transmission belt.

[0057] The transmission chain or transmission belt is inexpensive and easy to set up, which is conducive to driving the purging device 2 to move back and forth along the first direction A or the second direction B.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the drive device further includes a first guide rail 61 extending along a first direction A. A second drive unit is drivenly connected to the first guide rail 61. A first moving device 31 includes a first guide engagement portion mounted on the first guide rail 61. The first guide engagement portion is configured to roll engage with the first guide rail 61. The drive device further includes a second guide rail 62 extending along a second direction B. A second moving device 33 includes a second guide engagement portion mounted on the second guide rail 62. The second guide engagement portion is configured to roll engage with the second guide rail 62. For example, an automatic cleaning device may include a support device fixed relative to the ground and including two vertical support surfaces spaced apart along the second direction B, with both ends of the second guide rail 62 fixedly connected to the two vertical support surfaces, thereby extending along the second direction B.

[0059] The rolling engagement between the first guide fitting part and the first guide rail 61 facilitates the rapid and stable movement of the first moving device 31 along the first direction A. The rolling engagement between the second guide fitting part and the second guide rail 62 facilitates the rapid and stable movement of the second moving device 33 along the second direction B. The rolling engagement helps to reduce the friction between the first moving device 31 and the second moving device 33 during their movement, which helps to reduce the obstruction of the air outlet 2a during the cleaning process of the automatic cleaning equipment, and facilitates the smooth change of the blowing position of the blowing airflow, thereby improving the cleaning effect.

[0060] In some embodiments, the first guide engagement portion is slidably engaged with the first guide rail 61. The second guide engagement portion is slidably engaged with the second guide rail 62.

[0061] The sliding engagement between the first guide fitting part and the first guide rail 61 facilitates the precise movement of the first moving device 31 along the direction of extension of the first guide rail 61, and the sliding engagement between the second guide fitting part and the second guide rail 62 facilitates the precise movement of the second moving device 33 along the direction of extension of the second guide rail 62, thereby improving the cleaning effect.

[0062] In some embodiments, at least one of the first guide mating portion and the second guide mating portion includes a roller 300 and / or a slider and / or a sleeve. For example... Figure 1 and Figure 2 As shown, the first guide mating part and the second guide mating part include rollers 300. The rollers 300 are configured to roll into a first guide rail 61 that mates with the first guide mating part or to roll into a second guide rail 62 that mates with the second guide mating part.

[0063] The roller 300 rolls with the first guide rail 61 or the second guide rail 62, which helps to reduce resistance during movement, reduces wear between the first guide engagement part and the first guide rail 61, and between the second guide engagement part and the second guide rail 62, thereby helping to extend the service life of the automatic cleaning equipment.

[0064] like Figures 1 to 3 As shown, in some embodiments, the outer walls of the first guide rail 61 and the second guide rail 62 are cylindrical surfaces. The wheel surfaces of the roller 300 that rolls with the first guide rail 61 and the roller 300 that rolls with the second guide rail 62 have at least a portion of circular arcs in the axial section through the roller 300, thereby ensuring good fit with the first guide rail 61 and the second guide rail 62 and preventing them from easily disengaging.

[0065] In some embodiments, at least one of the first guide mating portion and the second guide mating portion includes a slider. The slider is configured to slide into a first guide rail 61 that mates with the first guide mating portion or a second guide rail 62 that mates with the second guide mating portion.

[0066] The slider slides into the first guide rail 61 or the second guide rail 62, which helps to increase the contact area of ​​the mating surfaces and thus improves the reliability of the fit.

[0067] In some embodiments, at least one of the first guide mating portion and the second guide mating portion includes a sleeve. The sleeve is configured to slide into a first guide rail 61 that mates with the first guide mating portion or to slide into a second guide rail 62 that mates with the second guide mating portion.

[0068] The sleeve has a simple structure, and after assembly, the sleeve and guide rail are positioned accurately and stably.

[0069] like Figures 1 to 3As shown, in some embodiments, the first guide mating part includes at least one first roller group, which includes two rollers 300. The two rollers 300 of the first roller group are respectively located on opposite sides of the first guide rail 61. For example, the axis of the rollers 300 of the first roller group extends along the second direction B, and the two rollers 300 of the first roller group are respectively located on both sides of the first guide rail 61 along a third direction C perpendicular to the first direction A and the second direction B, and aligned along the first direction A. In embodiments not shown, the two rollers 300 may also be staggered along the first direction A.

[0070] The two rollers 300 of the first roller group form a space between their surfaces that can accommodate the first guide rail 61. The two rollers 300 are located on opposite sides of the first guide rail 61, which helps to lock the first guide rail 61 between the two rollers 300 of the first roller group. This helps to resist the risk of the first moving device 31 tipping over or deviating from the first guide rail 61 during movement, and helps to ensure the smooth operation of the first moving device 31.

[0071] like Figures 1 to 3 As shown, in some embodiments, the automatic cleaning device includes two first guide rails 61 spaced apart along a second direction B. The first guide mating portion includes at least two first roller groups, with each first guide rail 61 corresponding to at least one first roller group. For example, the first guide mating portion may also include two first roller groups, with each roller group corresponding one-to-one with a first guide rail 61. The two first roller groups may be arranged opposite each other along the second direction B, or staggered along the first direction A. As another example, the first guide mating portion may also include two or more first roller groups, and the number of first roller groups corresponding to the two first guide rails 61 may be the same or different. Having the same number of first roller groups corresponding to the two first guide rails 61 helps to evenly distribute the load on the two first guide rails 61, which helps to improve the load-bearing capacity of the first guide rails 61, thereby helping to extend the service life of the first guide rails 61.

[0072] Setting up two first guide rails 61 helps to provide more stable support for the first moving device 31, and helps to reduce swaying or deviation caused by uneven force on a single guide rail, thereby improving the stability of the purging airflow ejected by the purging device 2.

[0073] like Figure 1 and Figure 2As shown, in some embodiments, the second guide mating portion includes at least one second roller group. The second roller group includes at least two rollers 300. At least one roller 300 of the second roller group and the other rollers 300 of the second roller group are respectively located on opposite sides of the second guide rail 62. For example, the axis of the rollers 300 of the second roller group extends along a third direction C, and two or more rollers 300 of the second roller group are respectively located on both sides of the second guide rail 62 along a first direction A.

[0074] The rollers 300 are distributed on opposite sides of the second guide rail 62. This design helps to reduce movement deviation caused by uneven wear of the rollers 300 or uneven surface of the second guide rail 62, and helps to make the rollers 300 move stably in a straight line on the second guide rail 62, thereby improving the smoothness of movement of the second moving device 33.

[0075] like Figure 1 and Figure 2 As shown, in some embodiments, the automatic cleaning device includes two second guide rails 62 spaced apart along a third direction C. The second guide mating part includes two second roller assemblies. The two second roller assemblies are arranged in a one-to-one correspondence with the two second guide rails 62.

[0076] Setting up two second guide rails 62 helps to provide more stable support for the second moving device 33 and improves the stability of the purging airflow ejected by the purging device 2.

[0077] like Figure 1 As shown, in some embodiments, the second roller group includes three rollers 300, which are respectively located on opposite sides of the corresponding second guide rail 62 along the first direction A.

[0078] The three rollers 300 of the second roller group are located on opposite sides of the corresponding second guide rail 62, forming a triangular structure. The triangular structure has strong structural stability, which helps to ensure the stable movement of the second roller group on the second guide rail 62. It also helps to improve the load capacity of the second moving device 33, thereby helping the second moving device 33 to stably drive the first guide rail 61, the first driving part and the purging device 2 to move synchronously along the second direction B.

[0079] like Figure 1 and Figure 2 As shown, in some embodiments, the automatic cleaning equipment further includes an air supply device 1. The air supply device 1 includes an air source and a connecting pipe. The first guide rail 61 has a hollow portion, and the connecting pipe is connected to the first guide rail 61 to form an air supply pipeline together with the first guide rail 61 that connects the air source and the air outlet 2a of the purging device 2.

[0080] The connection pipe and the first guide rail 61 together form an air supply pipeline, which helps to extend the length of the air supply pipeline, thereby ensuring the flow rate of the purging airflow ejected by the purging device 2. In addition, this arrangement helps to avoid setting up additional pipeline structures to provide purging airflow, and helps to reduce the size of the automatic cleaning equipment.

[0081] like Figure 1 and Figure 3 As shown, in some embodiments, the first drive unit further includes a connecting rod 35. The first end of the connecting rod 35 is rotatably connected to the transmission chain (or belt) of the first transmission device 32. For example, the first end of the connecting rod 35 can be rotatably connected to the transmission chain of the first transmission device 32 via a connecting chain buckle 36. The first moving device 31 may also include a first moving main body 310, with rollers 300 of the first guide engagement portion connected to both sides of the first moving main body 310 along the second direction B. The second end of the connecting rod 35 is hinged to the side of the first moving main body 310 along the first direction A near the second drive unit, thereby the connecting rod 35 transmits the driving force of the first transmission device 32 to the first moving main body 310, and the first guide engagement portion causes the first moving main body 310 to reciprocate in a direction consistent with the direction in which the first guide rail 61 extends.

[0082] The first transmission device 32 and the first moving device 31 are drivenly connected by a connecting rod 35. The first end of the connecting rod 35 rotates continuously in the same direction as the transmission chain and reverses direction at the extreme position along the first direction A of the transmission chain's rotation path, thereby driving the first moving device 31 to reciprocate along the first direction A. This arrangement is simple and compact, easy to assemble, and can drive the first moving device 31 to reciprocate without reversing the direction of the output structure (e.g., output shaft) of the first actuating device 4. This helps to extend the service life of the first actuating device 4 and improve the smoothness of the drive.

[0083] like Figure 1 As shown, in some embodiments, the automatic cleaning device further includes a first detection unit (not shown) and a second detection unit. The first detection unit is configured to detect the position of the air outlet 2a along a first direction A. A first drive unit is coupled to the first detection unit and configured to drive the cleaning device 2 to reciprocate along the first direction A based on the detection result of the first detection unit. The second detection unit is configured to detect the position of the air outlet 2a along a second direction B. The second drive unit is coupled to the second detection unit and configured to drive the first drive unit to reciprocate along the second direction B based on the detection result of the second detection unit. The first and second detection units may, for example, include position sensors, proximity switches, etc.

[0084] Setting up a first detection unit and a second detection unit helps to accurately locate the operating position of the air outlet 2a during the cleaning process, improves the accuracy of the operating position, and allows the air outlet 2a to flexibly adjust its movement route according to a preset path or the actual environment to cover all areas that need to be cleaned, thereby improving the cleaning effect and enhancing the automation level of the automatic cleaning equipment.

[0085] In some embodiments, the second detection unit may also include a counting disk, which is configured to detect the position of the second moving device 33 along the second direction B by detecting the output of the second actuator 38 of the second drive unit (e.g., the second actuator 38 is a motor, and the counting disk detects the number of rotations of the output shaft of the second actuator 38).

[0086] The second detection unit includes a counting disc, which facilitates the automatic cleaning equipment to clean multiple devices 100 that are equidistant from each other along the second direction B, thereby improving cleaning efficiency. In addition, the counting disc is simple to set up, which helps to reduce costs.

[0087] like Figure 2 and Figure 4 As shown, the purging device 2 also includes an air nozzle 20 and an air nozzle drive unit. The air nozzle 20 includes an air outlet 2a. The air nozzle drive unit is driven connected to the air nozzle 20 and is configured to drive the air nozzle 20 to reciprocate along a third direction C perpendicular to the first direction A and the second direction B.

[0088] The ability of the air nozzle 20 to reciprocate along the third direction C allows the air outlet 2a to be closer to the device 100 to be cleaned for cleaning, which is beneficial for cleaning the gaps or other hard-to-clean areas of the device 100.

[0089] like Figure 1 As shown, the air blowing device 2 includes a protective cover 22. The protective cover 22 is fitted over the outside of the air blowing nozzle drive unit.

[0090] The protective cover 22 helps protect the inside of the air nozzle drive unit from contamination and corrosion by the material on the equipment to be cleaned 100 that is stirred up by the blowing airflow, and helps extend the service life of the air nozzle drive unit.

[0091] like Figure 4 As shown, the automatic cleaning device also includes a third detection unit. The third detection unit is configured to detect the position of the air outlet 2a along a third direction C. A first drive unit is coupled to the third detection unit and is configured to drive the cleaning device 2 to move or stop moving along a first direction A based on the detection result of the third detection unit. The third detection unit may include, for example, a position sensor, a proximity switch, etc.

[0092] This setting facilitates automatic obstacle avoidance, preventing the air outlet 2a from interfering with the cleaning device 100 during its movement along the first direction A after it extends into the space formed by the inward recess of the outer wall of the device to be cleaned. This improves cleaning efficiency.

[0093] In some embodiments, the automatic cleaning device may also include a control device. The control device is signal-connected to the first detection unit, the second detection unit, the third detection unit, the first actuator 37, the second actuator 38, and the air nozzle drive unit, and is configured to control the first actuator 37, the second actuator 38, and the air nozzle drive unit according to the detection results of the first detection unit, the second detection unit, and the third detection unit, thereby controlling the blowing position of the air outlet 2a.

[0094] The control device automatically receives signals and helps to accurately control the purging position of the air outlet 2a, further improving the level of automation.

[0095] The control device may be implemented as a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic device, discrete hardware component, or any suitable combination thereof for performing the functions described in this disclosure.

[0097] The fermentation equipment of this disclosure has the advantages of the automatic cleaning equipment of this disclosure. The automatic cleaning equipment can clean independently along the first direction A and the second direction B, which is beneficial for switching the cleaning direction according to the setting direction of the machine body of the equipment to be cleaned.

[0098] The following combination Figures 1 to 4 The automatic cleaning device according to embodiments of this disclosure will be described in detail. In the following description, "up" and "down" correspond to the first direction A, "left" and "right" correspond to the second direction B, and "front" and "rear" correspond to the third direction C. The arrows inside the connecting pipes indicate the flow direction of the purging airflow.

[0099] like Figures 1 to 4As shown, the automatic cleaning device is used to spray a blowing airflow onto devices 100 to be cleaned at intervals in the left-right direction. The automatic cleaning device includes an air supply device 1, a blowing device 2, a drive device, a first detection unit, a second detection unit, and a third detection unit. The air supply device 1 is configured to provide a blowing airflow. The drive device includes a first drive unit and a second drive unit. The blowing device is disposed on the first drive unit.

The first drive unit is disposed on the second drive unit, and the second drive unit is driven connected to the first drive unit and is configured to drive the first drive unit to move left-right relative to the second drive unit. The first detection unit is configured to detect the vertical position of the air outlet 2a. The blowing device 2 includes an air nozzle 20 and an air nozzle drive unit. The air nozzle 20 includes an air outlet 2a, and the air nozzle drive unit is driven connected to the air nozzle 20 and is configured to drive the air nozzle 20 to move back and forth. The air nozzle drive unit is coupled to the first detection unit and configured to drive the air nozzle 20 to move back and forth based on the detection result of the first detection unit. The second detection unit is configured to detect the position of the air outlet 2a in the left-right direction. The second drive unit is coupled to the second detection unit and configured to drive the first drive unit to move left and right based on the detection result of the second detection unit, thereby causing the purging device 2 mounted on the first drive unit to move left and right as well. The third detection unit is configured to detect the position of the air outlet 2a in the front-back direction. The first drive unit is coupled to the third detection unit and configured to drive the purging device 2 to move up and down or stop moving based on the detection result of the third detection unit.

[0100] The first and second drive units operate independently, facilitating the separate control of the air outlet 2a of the blowing device 2 to move vertically or horizontally. The second drive unit cooperates with the second guide rail 62, ensuring stable left-right movement of the air outlet 2a of the blowing device 2. Through the first, second, and third detection units, this automatic cleaning device facilitates automatic cleaning of multiple devices 100 to be cleaned, ensures comprehensive coverage of the cleaning area of ​​each device 100 by the blowing airflow, and enables automatic obstacle avoidance, preventing interference between the blowing device 2 and the devices 100 during movement, thereby improving cleaning efficiency and effectiveness.

[0101] like Figure 1 and Figure 2As shown, the first drive unit includes a first actuator 37, a first moving device 31, a first transmission device 32, two first guide rails 61, and a retainer. The retainer includes an upper retainer 391 and a lower retainer 392. The upper retainer 391 is connected to the upper part of the two first guide rails 61 via two upper retainer connecting parts 3911 located on the left and right sides of the upper retainer 391. The lower retainer 392 is connected to the lower part of the two first guide rails 61 via two lower retainer connecting parts 3921 located on the left and right sides of the lower retainer 392. The upper retainer 391 and the lower retainer 392 are spaced apart in the vertical direction. The upper retainer 391, the lower retainer 392, and the two first guide rails 61 are fixedly connected, thereby facilitating the formation of a stable support structure.

[0102] The first actuator 37 is fixedly connected to the rear side of the upper retainer 391. The first transmission device 32 includes a transmission chain. The two transmission wheels of the first transmission device 32 are spaced vertically apart. The upper transmission wheel is fixedly connected to the upper retainer 391 and located in front of the upper retainer 391, and the lower transmission wheel is fixedly connected to the lower retainer 392 and located in front of the lower retainer 392. The first actuator 37 is drivenly connected to the upper transmission wheel of the first transmission device 32 to provide driving force for the first transmission device 32. The first transmission device 32 is drivenly connected to the first moving device 31 to drive the first moving device 31 to reciprocate along the first direction A, thereby causing the purging device 2, which is drivenly connected to the first moving device 31, to reciprocate along the first direction A.

[0103] like Figure 3 As shown, the first moving device 31 includes a first moving main body 310 and a first guiding engagement part. The first moving main body 310 is located between two first guide rails 61. The cross-section of the first moving main body 310 perpendicular to the third direction C is square. The first guiding engagement part is in rolling engagement with the first guide rails 61 and includes four first roller groups. The four first roller groups are respectively connected to the four corners of the first moving main body 310. Each first roller group includes two rollers 300, which are located on the front and rear sides of the rolling engagement first guide rail 61, respectively. Belt drive is used between the two first roller groups that are in rolling engagement with the same first guide rail 61. This arrangement helps to ensure synchronous movement between the various first roller groups, thereby facilitating the stable movement of the first moving device 31.

[0104] like Figure 3 As shown, the first drive unit also includes a connecting rod 35 and a connecting chain buckle 36. The first end of the connecting rod 35 is rotatably connected to the transmission chain of the first transmission device 32 via the connecting chain buckle 36, and moves along the trajectory of the transmission chain. The second end of the connecting rod 35 is rotatably connected to the upper part of the first moving main body 310.

[0105] like Figure 1 and Figure 2 As shown, the blowing device 2 is fixedly connected to the front side of the first moving main body 310, so that the air blowing port 2a is opened towards the equipment 100 to be cleaned.

[0106] The first actuator 37 drives the upper transmission wheel of the first transmission device 32 to rotate, thereby driving the transmission chain to transmit power. The connecting rod 35 moves along the trajectory of the transmission chain and drives the first moving main body 310 and the first guide mating part to move up and down along the first guide rail 61, thereby driving the purging device 2 connected to the first moving main body 310 to move up and down.

[0107] like Figure 1 As shown, the second drive unit includes a second actuator 38, a second moving device 33, and a second transmission device 34. The second transmission device 34 includes a transmission chain. The two transmission wheels of the second transmission device 34 are spaced apart. The second actuator 38 is driven to the left-side transmission wheel of the second transmission device 34, providing driving force to the second transmission device 34. The second transmission device 34 is driven to the second moving device 33, driving the second moving device 33 to move left and right, thereby causing the first drive unit, which is driven to the second moving device 33, to move left and right, and thus driving the purging device 2 of the first moving main body 310 connected to the first drive unit to move left and right.

[0108] like Figure 2 As shown, the second moving device 33 includes a second moving main body 330 and a second guide engagement part. The second guide engagement part includes two second roller groups. Each second roller group includes three rollers 300 and a triangular connecting plate, with the three rollers 300 respectively connected to the three corners of the triangular connecting plate. The second driving part includes two second guide rails 62, which extend in the left-right direction and are spaced apart front-back. The three rollers 300 of the second roller groups are in rolling engagement with one second guide rail 61, with two rollers 300 located above the second guide rail 62 and the other roller 300 located below the second guide rail 62. The rollers 300 of the two second roller groups located at the same position in the second roller groups are connected by a connecting rod extending in the third direction C. The second moving main body 330 includes three connecting rods. The second moving main body 330 also includes a support rod extending in the vertical direction. An upper retainer 391 is connected to the lower part of the support rod, thereby allowing the second moving main body 330 to move left and right and drive the first driving part to move left and right.

[0109] The second drive unit also includes two transmission chain baffles 340 and a baffle connecting rod fixedly connected to the rear of each transmission chain baffle 340. The rear end of the baffle connecting rod is fixedly connected to a support rod. The transmission chain baffles 340 are located in front of the transmission chain of the second transmission device 34 to prevent the transmission chain from deviating along the third direction C.

[0110] The second movable main body 330 also includes a connecting chain buckle mounting plate (not shown) connected between the two connecting rods located above. The second drive unit also includes a connecting chain buckle 36. The connecting chain buckle 36 of the second drive unit is mounted below the connecting chain buckle mounting plate. The second transmission device 34 drives the second movable main body 330 to move left and right via the connecting chain buckle 36.

[0111] like Figure 1 and Figure 2 As shown, the air supply device 1 includes an air source and a connecting pipe. The air source is configured to provide a purge airflow. The first guide rail 61 has a hollow portion. The first drive unit also includes a transverse connecting pipe connected between the bottoms of the two first guide rails 61. The connecting pipe is connected to the first guide rails 61 to form an air supply pipeline together with the first guide rails 61 and the transverse connecting pipe, connecting the air source and the air outlet 2a, so as to guide the purge airflow from the air source to the air outlet 2a and finally spray it from the air outlet 2a onto the device 100 to be cleaned.

[0112] The connecting pipes include a first pipe 11 and a second pipe 12. The first pipe 11 extends in a third direction C, with its first end connected to an air source and its second end connected to the upper part of the first guide rail 61 on the left. The second pipe 12 is located behind the first drive unit. The first end of the second pipe 12 is connected to the upper part of the first guide rail 61 on the right, and its second end is connected to the air outlet 2a of the purging device 2. The second pipe 12 is a flexible hose, which facilitates the movement of the purging device 2. The air nozzle drive unit and the air nozzle 20 of the purging device 2 are located in front of the first drive unit. The purging airflow flows from the first pipe 11 into the first guide rail 61 on the left, then through the transverse connecting pipe into the first guide rail 61 on the right, then into the second pipe 12, and finally from the second pipe 12 to the air outlet 2a.

[0113] The purging device 2 includes a bent pipe 21, a protective cover 22, an air nozzle 20, and an air nozzle drive unit. The bent pipe 21 includes two transverse pipe sections extending in a third direction C and a vertical pipe section connecting the two transverse pipe sections. The two transverse pipe sections are arranged one after the other, with the rear end of the rear transverse pipe section connected to the second end of the second pipe 12. The air nozzle 20 extends in a third direction C, with its first end connected to the front end of the bent pipe 21, and the port of its second end forming an air outlet 2a. The air nozzle drive unit is driven to the air nozzle 20 and is configured to drive the air nozzle 20 to reciprocate in a third direction C.

[0114] The nozzle drive unit includes a third actuator 24, a drive rod 231 extending along a third direction C, and a mounting plate 232 disposed perpendicular to the third direction C. The third actuator 24 is drivenly connected to the drive rod 231 and configured to drive the drive rod 231 to extend and retract back and forth. The mounting plate 232 is lobed and includes a small-diameter section and a large-diameter section. The large-diameter section of the mounting plate 232 is fixedly connected to the front end of the drive rod 231, and the small-diameter section of the mounting plate 232 includes a mounting hole in which the transverse pipe section of the bent pipe 21 located on the front side is installed. The lobed mounting plate 232, in conjunction with the position and shape of the bent pipe 21 and the drive rod 231 of the nozzle drive unit, facilitates the even distribution of stress at the connection points of the mounting plate 232 with the drive rod 231 and the bent pipe 21, respectively, which helps to avoid stress concentration and reduce the risk of connection failure.

[0115] The protective cover 22 is a bellows, which extends in a third direction C, and the front end of the bellows is connected to the rear side of the mounting plate 232. The bellows extends and retracts with the extension and retraction of the drive rod 231.

[0116] The first detection unit is configured to detect the height of the air inlet 2a. The first actuator 37 is coupled to the first detection unit and is configured to drive the transmission wheel of the first transmission device 32 located above to rotate according to the detection result of the first detection unit.

[0117] like Figure 1 As shown, the second detection unit includes a first position sensor, which comprises two first receivers 912 and a first transmitter 911. The first transmitter 911 is mounted above the second moving main body 330, and the center line of the first transmitter 911 extending along the first direction A coincides with the center line of the triangular connecting plate extending along the first direction A. The two first receivers 912 are mounted on a sensor bracket 80 located on top of the automatic cleaning device. The two first receivers 912 are positioned corresponding to two devices 100 to be cleaned, spaced apart along the second direction B. When the first receiver 912 on the left receives a signal, it indicates that the air outlet 2a has moved along the second direction B to the device 100 to be cleaned on the left, at which point the automatic cleaning device can clean the device to be cleaned on the left. When the first receiver 912 on the right receives a signal, it indicates that the air outlet 2a has moved along the second direction B to the device 100 to be cleaned on the right, at which point the automatic cleaning device can clean the device to be cleaned on the right. The first position sensor helps to improve the automation level of the automatic cleaning device, enabling the automatic cleaning device to automatically locate and accurately find the cleaning position, which is beneficial to improving cleaning efficiency.

[0118] like Figure 4As shown, the third detection unit is configured to detect the position of the air outlet 2a along the third direction C. The third detection unit includes a second position sensor, which includes two second receivers 922 and a second transmitter 921. The second transmitter 921 is fixedly connected to the housing of the air outlet drive unit, and the inner wall of the housing forms a hole, through which the drive rod 231 extends and retracts. The two second receivers 922 are mounted on the front transverse pipe section of the bent pipe 21 and are spaced apart along the third direction C. When the second receiver 922 on the front side receives a signal, it indicates that the air outlet 2a is in the maximum contraction position. When the second receiver 922 on the rear side receives a signal, it indicates that the air outlet 2a is in the maximum extension position. The first drive unit is coupled to the second position sensor and is configured to drive the purging device 2 to move or stop moving based on the detection result of the second position sensor. When the air outlet 2a is detected to be in the maximum extension position, the first actuator 37 of the first drive unit stops outputting, causing the purging device 2 to stop moving. When the air inlet 2a is detected to be in its maximum retracted position, the first actuator 37 of the first drive unit is activated, causing the purging device 2 to move up and down. The distance L between the maximum retracted position and the maximum extended position along the third direction C is denoted as L.

[0119] The second position sensor helps to detect the position of the air nozzle 2a relative to the device to be cleaned 100 along the third direction C, thereby helping to avoid interference and collision between the air nozzle 20 and the device to be cleaned 100 when the first drive unit drives the blowing device 2 to move up and down.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and not to limit them; although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this disclosure or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this disclosure.
