Description

Technical Field

[0001] This invention relates to the field of SMT processing fixture cleaning technology, and in particular to a three-layer nozzle cleaning machine. Background Technology

[0002] After SMT placement, the nozzles that hold the PCB board in place need to be cleaned to prevent clogging and ensure suction power. Currently, the cleaning process involves placing the nozzle holder in a cleaning chamber for rinsing and then air-drying.

[0003] However, in practice, the nozzles are manually placed into the cleaning tank, soaked for a period of time, and then removed from the tank and dried. This manual operation is time-consuming, labor-intensive, inefficient, and results in high labor costs. Currently, mechanized cleaning equipment is available on the market. Traditional cleaning equipment is designed with a two-section or flat three-section structure. During the drying process, water droplets splash everywhere, making it difficult to effectively blow away the water droplets from the nozzles. This leads to inaccurate detection during subsequent drying, resulting in misjudgments that the nozzles are not clean enough, requiring repeated cleaning and reducing efficiency. Furthermore, the water droplets splashing onto the worktable create a constantly damp working environment, making the equipment prone to rust, leading to high maintenance costs and affecting the equipment's lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide a three-layer nozzle cleaning machine to solve the problems of time-consuming and labor-intensive nozzle cleaning operations, low efficiency, and high labor costs in related technologies. Furthermore, traditional drying mechanisms cause water droplets to splash everywhere during the drying process, failing to effectively blow away the water droplets from the nozzles. This leads to inaccurate detection during subsequent drying tests, misjudging that the nozzles are not clean enough, and requiring repeated cleaning, thus reducing efficiency. By setting up a vertical three-layer cleaning and drying mechanism, the water droplets on the nozzles can be blown away more effectively without interfering with the subsequent testing steps. Additionally, the water droplets on the nozzles are blown off by the air knife assembly into a sealed drying tunnel to maintain a dry working environment.

[0012] In a preferred embodiment of the present invention, a three-section lifting assembly is used to transfer a cleaning tray to be cleaned. The three-section lifting assembly is provided with several vertical slide bars, horizontal plates A and B sliding down the several vertical slide bars, and a horizontal plate C located at the bottom of the vertical slide bars, and a first telescopic drive source and a second telescopic drive source respectively driving the horizontal plates A and B to move up and down.

[0013] In a preferred embodiment of the present invention, the sealed air-drying tunnel has a feed inlet, and air knife groups are arranged on the upper and lower sides of the feed inlet. The air direction of the air knife groups is towards the length direction of the sealed air-drying tunnel. The sealed air-drying tunnel is provided with a feeding push assembly for receiving the cleaning tray to be air-dried and sending the cleaning tray into the sealed air-drying tunnel.

[0014] In a preferred embodiment of the present invention, the feeding and pushing assembly is provided with horizontal guide rods and horizontal sliding cylinders respectively located on both sides of the sealed air-drying tunnel. The horizontal guide rods are provided with linear bearings. The feeding and pushing assembly is also provided with a material-bearing feeding plate. The two sides of the material-bearing feeding plate are respectively connected to the slide seat of the horizontal sliding cylinder and the linear bearing. The material-bearing feeding plate is driven by the horizontal sliding cylinder to drive the cleaning tray to be air-dried into the sealed air-drying tunnel through the feed port.

[0016] In a preferred embodiment of the present invention, a return water tank is provided at the bottom of the sealed air-drying tunnel, and a split adapter is provided at the bottom of the return water tank. The split adapter is connected to the cleaning water tank through a water pipe.

[0017] In a preferred embodiment of the present invention, a positioning correction component is provided between the first vision detection component and the size detection component.

[0018] In a preferred embodiment of the present invention, the first visual detection component includes a first camera, a prism, and a first light source, and the second visual detection component includes a second camera and a second light source.

[0019] The beneficial effects of the three-layer nozzle cleaning machine provided in this application embodiment are as follows: Compared with the prior art, the nozzle clamping plate containing the nozzles is installed on the quick-release clamp. The moving truss drives the second vision detection component and the flow detection gripping component to move above the quick-release clamp. The second vision detection component scans the QR code of the nozzles on the quick-release clamp to distinguish the nozzle model. At the same time, the second vision detection component takes a picture of the nozzles on the nozzle clamping plate and feeds the picture back to the PLC control device. The PLC control device determines the position of the nozzles on the nozzle clamping plate and whether there is blockage or accumulation of debris in the nozzle vents. The flow detection gripping component grabs and moves the nozzles on the nozzle clamping plate to the size detection component to detect the height and diameter of the nozzles, so as to place nozzles of different sizes on the cleaning tray. After the detection is completed, the flow detection gripping component places the nozzles on the cleaning tray, and the three-stage lifting component moves the cleaning tray down into the cleaning water tank for cleaning. After cleaning, the cleaning tray is moved to the sealed drying tunnel by the three-section lifting assembly. The feeding push assembly on the sealed drying tunnel pushes the cleaning tray into the tunnel. The air knife assembly blows air along the length of the sealed drying tunnel to blow away the water droplets on the suction cups and dry the nozzles. After drying, the cleaning tray exits the sealed drying tunnel and is moved back to the origin by the three-section lifting assembly. The moving truss drives the flow detection gripping assembly to move down, allowing it to grab the nozzles. The flow detection gripping assembly blows air onto the nozzles and detects the flow rate. Because the air gripper has a sealing groove, it can better detect the flow rate of the nozzles. After detection, the flow detection gripping assembly moves to the first vision detection assembly, which takes a picture of the nozzles and sends the picture to the PLC control device. The PLC control device determines whether there is any blockage or accumulation of debris at the nozzle air outlet. If it passes the test, the nozzles are placed on the nozzle clamping plate.

[0020] The invention features a simple structure. Compared to the flat three-section type, the vertical three-layer cleaning and drying mechanism significantly saves operating space and reduces machine size, thereby saving equipment space. It can also more effectively blow away water droplets on the suction nozzle without interfering with the next step of detection. Furthermore, the water droplets on the suction nozzle are blown off by the air knife group into the sealed drying tunnel to maintain a dry working environment.

[0021] The three-layer nozzle cleaning machine of this invention can realize automated cleaning and drying of nozzles, eliminating manual operation steps, saving time and effort, increasing efficiency, and reducing labor costs. Attached Figure Description

[0032] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 This embodiment provides a three-layer nozzle cleaning machine, including a chassis 10, a nozzle clamping tray quick-assembly and detection mechanism 20, a barcode scanning and transfer detection mechanism 30, and a vertical three-layer cleaning and drying mechanism 40, all housed within the chassis 10. A PLC control device 50 is located on the lower inner side of the chassis 10 to control the operation of the nozzle clamping tray quick-assembly and detection mechanism 20, the barcode scanning and transfer detection mechanism 30, and the vertical three-layer cleaning and drying mechanism 40. The PLC control device 50 has a display screen.

[0034] The nozzle clamp quick-release and inspection mechanism 20 is mainly used for clamping the nozzle clamp 211 and inspecting the cleaned nozzles. The mechanism includes a quick-release clamp 21, a first vision inspection component 22 located to the side of the quick-release clamp 21 for detecting whether the cleaned nozzles are clogged and feeding the inspection information back to the PLC control device 50, and a size inspection component 23 arranged alongside the first vision inspection component 22 for detecting nozzle dimensions and electrically connected to the PLC control device 50. An air column 24 is located to the side of the first vision inspection component, fixed to the worktable inside the chassis 10. An air pipe connected to the air source processor is installed at the bottom of the air column 24. The air column 24 is used for secondary drying of the cleaned nozzles. The quick-release clamp 21 includes a fixing base 210 and a nozzle clamp 211 clamped to the fixing base 210. A restraint mechanism for the nozzle clamp 211 is located on the front side of the fixing base 210. The clamping block moves along the front side of the fixed base 210. The front side of the suction cup 211 is provided with a limiting block that cooperates with the fixed block to limit the movement. The limiting block is inserted into the fixed block. By pressing down the suction cup 211 or rotating the rotatable buckle 212 provided on the rear side of the fixed base 210, the buckle 212 is fastened to the suction cup 211, limiting the suction cup 211 on the fixed base 210, thereby realizing the quick installation of the suction cup 211. In addition, the first vision inspection component 22 includes a first camera 220 horizontally set on the worktable of the chassis 10. A prism is provided on the outside of the lens of the first camera 220 to refract light onto the lens. A first light source 221 is installed above the prism. The first light source 221 increases the light, so that the light refracted by the prism can clearly illuminate the suction cup, improve the clarity of the camera, facilitate the processing and analysis of the PLC control device 50, and ensure that the suction cup is clean.

[0035] In addition, the size detection component 23 includes a side light source 230 at the same level as the first light source 221. A side camera 231 is provided in the direct direction of the light from the side light source 230. The side camera 231 is fixed on the workbench of the chassis 10 and electrically connected to the PLC control device 50. The barcode scanning and transfer detection mechanism 30 moves the gripped nozzle from the nozzle clamp 211 between the side camera 231 and the side light source 230. The side camera 231 takes a picture and transmits the picture to the PLC control device 50. The PLC control device 50 determines the size of the nozzle. The size detection facilitates the placement of nozzles of different sizes and models on the cleaning tray 60 of the vertical three-layer cleaning and drying mechanism 40 with different aperture areas, preventing the nozzles from falling off the cleaning tray 60 during cleaning.

[0036] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7Specifically, the barcode scanning transplanting detection mechanism 30 is used to scan QR codes to identify the model of the suction nozzle, detect whether the suction nozzle is blocked, position the suction nozzle, and move the suction nozzle. The barcode scanning transplanting detection mechanism 30 is equipped with a movable truss 31, a flow detection gripping component 32 located on the movable truss 31 for gripping the suction nozzle on the suction nozzle clamp 211 and for blowing air and detecting the flow of the suction nozzle, and a second vision detection component 33 located on the flow detection gripping component 32 for scanning QR codes and detecting suction nozzle blockage and feeding the information back to the PLC control device 50. The flow detection gripping component 32 has a pneumatic gripper 320 with a sealing groove 321.

[0037] The movable truss 31 includes a Y-axis moving mechanism 310, an X-axis moving mechanism 311 mounted on the Y-axis moving mechanism 310, and a Z-axis moving mechanism 312 mounted on the X-axis moving mechanism 311. The first vision detection component 22 and the pneumatic gripper 320 are mounted on the Z-axis moving mechanism 312. The Y-axis moving mechanism 310, X-axis moving mechanism 311, and Z-axis moving mechanism 312 are all driven by motors. The Y-axis moving mechanism 310, X-axis moving mechanism 311, and Z-axis moving mechanism 312 can be configured as lead screws, belts, or chains. In this embodiment, the Y-axis moving mechanism 310, X-axis moving mechanism 311, and Z-axis moving mechanism 312 are configured as lead screws that cooperate with motors for transmission. Furthermore, the Y-axis moving mechanism 310, X-axis moving mechanism 311, and Z-axis moving mechanism 312 are all controlled by a PLC control device 50, reducing manual intervention, automating operation, and improving the working efficiency of the equipment.

[0038] Furthermore, the flow detection gripping component 32 is fixed on the Z-axis moving mechanism 312, which drives the flow detection gripping component 32 to move up and down. The flow detection gripping component 32 is equipped with a clamping air blowing block 322 fixed on the pneumatic gripper 320. The clamping air blowing block 322 is equipped with an air blowing shaft 323, which is inserted into the air inlet of the suction nozzle. The clamping air blowing block 322 is also equipped with a three-pronged air pipe connector that communicates with the air blowing shaft 323. The three-pronged air pipe connector is connected to a vacuum generator and an air source processor respectively through air pipes. The vacuum generator and the air source processor... The device is installed on the outer wall of the chassis 10. It should be noted that when the gripper 320 grabs the nozzle to be cleaned, the air blowing shaft 323 is not ventilated to avoid debris splashing. When the gripper 320 grabs the cleaned and dried nozzle, the air blowing shaft 323 is inserted into the nozzle's air inlet, the air source processor is activated, the air blowing shaft 323 blows air to detect the nozzle's flow rate, determines the size of the nozzle's airflow, and thus detects whether the nozzle is blocked. After the detection is completed, the air source processor is turned off, the vacuum generator is activated, the air blowing shaft 323 draws air, and the nozzle pressure value is detected to detect the nozzle's suction force. In addition, the pneumatic gripper 320 is a finger gripper 320. Several clamps are installed at the output end of the finger gripper 320. The clamps are provided with sealing grooves 321. The finger gripper 320 drives the clamps to grasp the suction nozzle. The edge of the suction nozzle is inserted into the sealing groove 321. When the air blowing shaft 323 blows or sucks air, it can prevent gas from flowing out from the connection between the suction nozzle and the clamp, thereby improving the accuracy of detecting the flow rate and pressure value of the suction nozzle, and at the same time saving air source.

[0039] Furthermore, the second vision detection component 33 is connected to the Z-axis moving mechanism 312 via a fixed plate, and the flow detection gripping component 32 is also connected to the Z-axis moving mechanism 312 via a fixed plate. The Z-axis moving mechanism 312 drives the fixed plate to move up and down, thereby driving the second vision detection component 33 and the flow detection gripping component 32 to move up and down. The second vision detection component 33 is located on the side of the pneumatic gripper 320. The second vision detection component 33 is equipped with a vertically arranged second camera 330. A second light source 331 is located below the second camera 330. The second camera 330 takes pictures of the nozzle to be cleaned and scans the QR code. The second camera 330 feeds the signal back to the PLC control device 50. The PLC control device 50 analyzes the signal to determine the nozzle model and detects whether the nozzle is blocked or has residue.

[0040] When the barcode scanning transplanting detection mechanism 30 is working, when it is necessary to move the nozzles on the nozzle clamp 211, the Y-axis moving mechanism 310 drives the second vision detection component 33 and the flow detection gripping component 32 to move back and forth onto the nozzle clamp 211 of the quick-release clamp 21. The second camera 330 takes pictures of the nozzle clamp 211 and scans the QR code to identify the nozzle model. The PLC control device 50 determines whether the nozzle is blocked or has residue, and determines the position of the nozzle. The X-axis moving mechanism 311 drives the flow detection gripping component 32 to move left and right above the nozzle where residue or blockage is determined. Then, the Z-axis moving mechanism 312 drives the flow detection and gripping component 32 to move downwards, and the gripper 320 grips the nozzle. In conjunction with the Y-axis moving mechanism 310, the X-axis moving mechanism 311, and the Z-axis moving mechanism 312, the nozzle gripped by the gripper 320 is moved between the side camera 231 and the side light source 230. The side camera 231 takes a picture and transmits the image to the PLC control device 50. The PLC control device 50 determines the size of the nozzle. This size detection facilitates the placement of nozzles of different sizes onto the cleaning tray 60 of the vertical three-layer cleaning and drying mechanism 40, where different apertures are present. The area is designated as the cleaning plate 60. When it needs to be moved to a cleaned nozzle, the Y-axis moving mechanism 310 drives the second vision detection component 33 and the flow detection gripping component 32 to move back and forth above the cleaning plate 60. The second vision detection component 33 takes pictures of the nozzles on the cleaning plate 60 to detect whether the nozzles on the cleaning plate 60 are clean or have water droplets remaining. After the detection is completed, the X-axis moving mechanism 311 and the Z-axis moving mechanism 312 move together to make the gripper 320 grasp the nozzle. At this time, the air blowing shaft 323 is inserted into the air outlet of the nozzle, the air source processor is activated, and the air blowing shaft 323 blows air to detect the flow rate of the nozzle. The air source processor is turned off, the vacuum generator is started, and the air blowing shaft 323 draws in air to detect the air pressure value of the nozzle and thus detect the suction force of the nozzle. After the detection is completed, the Y-axis moving mechanism 310 is driven and the X-axis moving mechanism 311 moves to move the nozzle on the air gripper 320 to the air blowing column 24, where the air blowing column 24 dries the nozzle a second time. After drying, the Y-axis moving mechanism 310 is driven and the X-axis moving mechanism 311 moves to place the cleaned nozzle on the nozzle clamp 211.

[0041] Preferably, in order to prevent the suction nozzle gripped by the pneumatic gripper 320 from tilting or shifting, a positioning correction component 11 is provided on the worktable between the first light source 221 and the side light source 230. The positioning correction component 11 is provided with a correction fixing block. The correction fixing block is provided with a correction block. The pneumatic gripper 320 moves the suction nozzle to the correction block. The PLC control device 50 controls the pneumatic gripper 320 to release the suction nozzle, place the suction nozzle on the correction block, and straighten the position of the suction nozzle. The pneumatic gripper 320 grips the suction nozzle again to ensure that the suction nozzle can be quickly and accurately placed on the suction nozzle chuck 211 or the cleaning tray 60.

[0042] Please see Figure 8 , Figure 9 , Figure 10 The vertical three-layer cleaning and drying mechanism 40 is the main component of the equipment. Located to the side of the first visual inspection component 22, the vertical three-layer cleaning and drying mechanism 40 has a slot on the workbench for its movement, used for cleaning and drying the nozzles. The vertical three-layer cleaning and drying mechanism 40 includes a three-section lifting assembly 41 for moving the cleaning tray 60 up and down, a cleaning water tank 42 located to the side of the three-section lifting assembly 41 for cleaning the nozzles, and a sealed drying tunnel 43 located above the cleaning water tank 42 for drying the nozzles and containing an air knife assembly 430. The three-section lifting assembly 41 is used to move the cleaning tray 60 to be cleaned. The three-section lifting assembly 41 includes several vertical slide bars 410, horizontal plates A411 and B412 sliding down the vertical slide bars 410, and a... The vertical slide bar 410 has a horizontal plate C413 at the bottom, a first telescopic drive source 414 and a second telescopic drive source 415 that drive the horizontal plates A411 and B412 to move up and down respectively. The top of the horizontal plate A411 is provided with a material receiving frame 4110, which is equipped with an electric self-locking plate controlled by a PLC control device 50. The cleaning tray 60 is locked on the material receiving frame 4110. The horizontal plate C413 is provided with a slot for the first telescopic drive source 414 to move. The output end of the first telescopic drive source 414 is connected to the bottom of the horizontal plate A411 and is fixed to the horizontal plate B412 to drive the horizontal plate A411 to rise and fall. The second telescopic drive source 415 is fixed to the horizontal plate C413 and is connected to the bottom of the horizontal plate B412 to drive the horizontal plate B412 to rise and fall. It should be noted that the first telescopic drive source 414 and the second telescopic drive source 415 can be lifting cylinders, electric cylinders or other types of cylinders, or other telescopic drive source components.

[0043] A left and right side correction component 12 and a rear side correction component 13 are symmetrically arranged on the left and right sides of the workbench. The left and right side correction components 12 and the rear side correction component 13 are used to correct the position of the cleaning tray 60. Each of the left and right side correction components 12 is equipped with a first telescopic cylinder fixed on the workbench and whose output end extends and retracts towards the workbench. The output end of the first telescopic cylinder has two guide positioning posts. The two first telescopic cylinders extend towards the workbench so that the guide positioning posts abut against the left and right sides of the cleaning tray 60 to prevent the cleaning tray 60 from moving left and right. The rear side correction component 13 is equipped with two second telescopic cylinders whose output ends extend and retract towards the workbench. The output end of each of the two second telescopic cylinders is equipped with a limit plate. The two second telescopic cylinders extend towards the workbench so that the limit plate abuts against the rear side of the cleaning tray 60 to prevent the cleaning tray 60 from retracting.

[0044] The cleaning water tank 42 is fixed on the casing 10. It should be noted that the cleaning water tank 42 can be cleaned by ultrasonic cleaning, high-pressure spray gun cleaning, or existing rinsing technology, which will not be described in detail in this application.

[0045] The sealed air-drying tunnel 43 is fixed to the casing 10. The sealed air-drying tunnel 43 has a feed inlet, and air knife assemblies 430 are located on the upper and lower sides of the feed inlet. The airflow direction of the air knife assemblies 430 is along the length of the sealed air-drying tunnel 43. The sealed air-drying tunnel 43 is equipped with a feeding push assembly 431 for receiving the drying and cleaning trays 60 and feeding the trays 60 into the sealed air-drying tunnel 43. The feeding push assembly 431 has horizontal guide rods 432 and horizontal sliding cylinders 433 respectively located on both sides of the sealed air-drying tunnel 43. The horizontal guide rods 432 are equipped with linear bearings. The feeding push assembly 431 also... A material-bearing feed plate 434 is provided, with its two sides connected to the slide seats and linear bearings of a horizontal sliding cylinder 433, respectively. The horizontal sliding cylinder 433 drives the material-bearing feed plate 434 to move the cleaning tray 60 to be dried into the sealed drying tunnel 43 through the feed inlet. An air-blowing feed plate 435 is provided at the end of the material-bearing feed plate 434. Slide grooves 436 are provided on the left and right sides of the sealed drying tunnel 43. The air-blowing feed plate 435 slides in cooperation with the slide grooves 436. The air-blowing feed plate 435 is provided, and guided by the slide grooves 436, the material-bearing feed plate 434 can be quickly moved. The cleaning tray 60, awaiting drying, enters the sealed air-drying tunnel 43. The first telescopic drive source 414 drives the horizontal plate A411 to move the cleaning tray 60, containing the suction nozzle to be cleaned, downwards into the cleaning water tank 42. The cleaning tank 42 then rinses and soaks the tray. After cleaning, the second telescopic drive source 415 drives the horizontal plate B412 upwards, causing the horizontal plate A411 to transport the cleaned tray 60 to the feeding push assembly 431. The electric self-locking plate, controlled by the PLC control device 50, unlocks, and the feeding push assembly 431 pushes the cleaning tray 60 into the sealed air-drying tunnel 43. The air-drying tunnel 43 dries the suction nozzle on the cleaning tray 60 and the cleaning tray 60. After drying, the feeding push assembly 431 pushes the cleaning tray 60 out of the sealed air-drying tunnel 43. Then, the first telescopic drive source 414 drives the horizontal plate A411 to move the dried cleaning tray 60 upward. By setting the sealed air-drying tunnel 43, water droplets can be prevented from splashing when the air knife assembly 430 blows air, so that water droplets can only splash inside the tunnel. At the same time, the air direction of the air knife assembly 430 blows in the direction of the length of the sealed air-drying tunnel 43, which can prevent the splashed water droplets from splashing onto the suction nozzle that is dried in front.

[0046] Furthermore, a return water tank 437 is provided at the bottom of the sealed drying tunnel 43. A connector is located at the bottom of the return water tank 437, which connects to the cleaning water tank 42 via a water pipe. Water resources can be recycled through the return water tank 437, reducing water waste. Even further, a water exchange port is provided at the bottom of the cleaning water tank 42, through which wastewater can be replaced and residue accumulated in the cleaning water tank 42 can be discharged.

[0047] The working principle of this application is as follows: The nozzle to be cleaned is placed on the nozzle clamp 211, which is installed on the quick-release clamp 21. When it is necessary to move the nozzle on the nozzle clamp 211, the Y-axis moving mechanism 310 drives the second vision detection component 33 and the flow detection grasping component 32 to move back and forth onto the nozzle clamp 211 of the quick-release clamp 21. The second camera 330 takes pictures of the nozzle clamp 211 and scans the QR code to identify the nozzle model. The PLC control device 50 determines whether the nozzle is blocked or has residue, and determines the position of the nozzle. The X-axis moving mechanism 311 drives the flow detection grasping component 32 to move left and right to determine the position. Above the nozzle with residue or blockage, the flow detection gripping component 32 is driven down by the Z-axis moving mechanism 312. The nozzle is gripped by the pneumatic gripper 320 and moved in conjunction with the Y-axis moving mechanism 310, X-axis moving mechanism 311 and Z-axis moving mechanism 312 to move the nozzle to the calibration block for calibration. After calibration, the nozzle gripped by the pneumatic gripper 320 is moved between the side camera 231 and the side light source 230. The side camera 231 takes a picture and transmits the picture to the PLC control device 50. The PLC control device 50 determines the size of the nozzle. The size detection makes it convenient to place nozzles of different sizes and models on the cleaning tray 60 in areas with different apertures.

[0048] After the cleaning tray 60 is filled, the first telescopic drive source 414 drives the horizontal plate A411 to move the cleaning tray 60 containing the suction nozzles to be cleaned downwards into the cleaning water tank 42, where it is rinsed and soaked. After cleaning, the second telescopic drive source 415 drives the horizontal plate B412 upwards, causing the horizontal plate A411 to transport the cleaned cleaning tray 60 to the feeding push assembly 431. The electric self-locking plate controlled by the PLC control device 50 unlocks, and the feeding push assembly 431 pushes the cleaning tray 60 into the sealed air drying tunnel 43, where the sealed air drying tunnel 43 cleans the cleaning tray 60. The suction nozzle and cleaning disc 60 on the 0 are dried. By setting a sealed air drying tunnel 43, when the air knife group 430 blows air, water droplets can be prevented from splashing. Water droplets can only splash inside the tunnel. At the same time, the air direction of the air knife group 430 is blown in the length direction of the sealed air drying tunnel 43 to prevent the splashed water droplets from splashing back onto the suction nozzle that is being dried in front. After drying is completed, the feeding push component 431 pushes the cleaning disc 60 out of the sealed air drying tunnel 43. Then, the first telescopic drive source 414 drives the horizontal plate A411 to move the dried cleaning disc 60 upward, so that the cleaning disc 60 rises to its original position.

[0049] When it is necessary to move to the cleaned nozzle, the Y-axis moving mechanism 310 drives the second vision detection component 33 and the flow detection gripping component 32 to move back and forth above the cleaning tray 60. The second vision detection component 33 takes pictures of the nozzles on the cleaning tray 60 to detect whether the nozzles on the cleaning tray 60 are clean or have water droplets remaining. After the detection is completed, the X-axis moving mechanism 311 and the Z-axis moving mechanism 312 move together to make the gripper 320 grasp the nozzle. The gripper 320 will not grasp the nozzle if it is not clean or has water droplets. At this time, when the gripper 320 grasps the nozzle, the air blowing shaft 323 is inserted into the air outlet of the nozzle, the air source processor is activated, and the air blowing shaft 323 blows air. The flow rate of the suction nozzle is detected to determine the size of the airflow and thus detect whether the nozzle is blocked. After the detection is completed, the air source processor is turned off, the vacuum generator is started, the air blowing shaft 323 draws in air, and the pressure value of the suction nozzle is detected to detect the suction force of the suction nozzle. After the detection is completed, the Y-axis moving mechanism 310 is driven and the X-axis moving mechanism 311 moves again to move the suction nozzle on the air gripper 320 to the air blowing column 24, where the air blowing column 24 dries the suction nozzle a second time. After drying, the Y-axis moving mechanism 310 is driven and the X-axis moving mechanism 311 and Z-axis moving mechanism 312 move again to place the cleaned suction nozzle on the suction nozzle clamp 211.

[0050] This invention features a simple structure. Compared to a flat, three-section design, the vertical, three-layer cleaning and drying mechanism 40 significantly saves operating space, reduces machine size, and thus conserves equipment space. It also more effectively blows away water droplets from the nozzles without interfering with subsequent inspection steps. Furthermore, water droplets on the nozzles are blown off by the air knife assembly into a sealed drying tunnel, maintaining a dry working environment. This three-layer nozzle cleaning machine automates nozzle cleaning and drying, eliminating manual steps, saving time and labor, increasing efficiency, and reducing labor costs.
