DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] The present invention provides a sensor automatic assembly test machine, such as Figures 1 to 4 As shown, it includes a frame 1, on which a loading component, an assembly and testing component, and a unloading component are arranged; The feeding assembly includes a vibration plate 2, a connecting block 3, a conveying rail 4, an O-ring 5, a fixing seat 6, a mounting groove and an adjustment mechanism. The vibration plate 2 is fixedly installed on the frame 1, one end of the connecting block 3 is fixedly connected to the vibration plate 2, and the other end of the connecting block 3 is fixedly connected to the conveying rail 4. The bottom of the conveying rail 4 is fixedly installed with a fixing seat 6, and the bottom of the fixing seat 6 is fixedly installed with the frame 1. An O-ring 5 is provided in the middle of the connecting block 3 and the conveying rail 4. Mounting grooves are provided on the inner walls on both sides of the conveying rail 4, and an adjustment mechanism is provided inside the mounting groove.

[0019] The feeding assembly facilitates automatic loading of sensor components and then screening and diversion into designated workstations. The assembly and testing assembly first assembles them and then tests their electrical and sealing properties. After assembly is completed, the finished products are collected by the unloading workstation on a plate and screened and packaged to separate them from good products. When the O-ring 5 is loaded through the feeding mechanism, the O-ring 5 is transported to the connecting block 3 and the conveying track 4 by starting the vibration plate 2, and the conveying track 4 is supported by the fixed seat 6 to improve the stability of the conveying track 4 during transmission. The conveying track 4 transports the O-ring 5 to the designated workstation for assembly and testing. When dust is generated on the conveying track 4, the adjustment mechanism is started to clean and protect the conveying track 4 to prevent the rubber O-ring 5 from rubbing against the track to generate electrostatic adsorption, and the O-ring 5 is deformed due to frictional heat, resulting in track jamming, and can prevent dust and metal debris from adhering to the surface of the O-ring 5, affecting the assembly effect.

[0020] like Figures 3 to 6 As shown, the adjustment mechanism includes a first motor 7, a rotating rod 8, a moving block 9, a rotating structure, a first fixed block 10, a second fixed block 11, a cleaning structure and a protective structure; The first motor 7 is fixedly installed on the inner wall of the mounting groove, one end of the rotating rod 8 is fixedly connected to the output end of the first motor 7, and the other end of the rotating rod 8 is rotatably connected to the inner wall of the mounting groove. The middle part of the moving block 9 is threadedly connected to the rotating rod 8, and the upper and lower sides of the moving block 9 are slidably connected to the inner wall of the mounting groove. The moving block 9 is provided with a rotating structure near the O-ring 5 side, and a first fixed block 10 and a second fixed block 11 are provided on the rotating structure. A cleaning structure and a protective structure are respectively provided inside the first fixed block 10 and the second fixed block 11. A movable opening 12 is opened at the end of the transmission track 4 away from the vibration disk 2, and the first fixed block 10 and the second fixed block 11 are both located at the movable opening 12. The first fixed block 10 and the second fixed block 11 are arranged vertically, and movable grooves are opened at the bottom ends of the first fixed block 10 and the second fixed block 11. The cleaning structure and the protective structure are respectively located in the movable grooves, and the first fixed block 10 and the second fixed block 11 are symmetrically arranged with the center of the transmission track 4.

[0021] The cleaning structure includes a blower 13 and a cleaning tube 14. The blower 13 is fixedly installed on the movable groove of the first fixed block 10. The cleaning tube 14 is fixedly installed on the bottom of the blower 13. One end of the cleaning tube 14 passes through the movable groove and extends to the bottom of the first fixed block 10.

[0022] The movable opening 12 facilitates the rotation structure to drive the first fixed block 10 and the second fixed block 11 to rotate, so that after the cleaning structure in the first fixed block 10 is cleaned, the protection structure in the second fixed block 11 can be used to protect the conveying track 4. The symmetrically arranged first fixed block 10 and the second fixed block 11 can correspond to the inner walls on both sides of the conveying track 4, thereby improving the cleaning and protection effects. When it is necessary to clean and protect the conveying track 4, first stop the vibration plate 2 to convey the O-ring 5, and expose the inner wall of the conveying track 4. The first fixed block 10 is rotated to the inner wall of the conveying track 4 through the rotation structure, and keeps it perpendicular to the conveying track 4, while the second fixed block 11 is rotated into the installation groove and keeps it parallel to the conveying track 4. The first motor 7 is started to drive the rotating rod 8 to rotate along the installation groove. The upper and lower sides of block 9 are slidably connected to the inner wall of the installation groove, so that the moving block 9 will not rotate when the rotating rod 8 rotates. The moving block 9 drives the rotating structure, the first fixed block 10 and the second fixed block 11 to move back and forth along the rotating rod 8 in the installation groove, and the hair dryer 13 is started at the same time. When the first fixed block 10 moves, it drives the hair dryer 13 and the cleaning tube 14 to move back and forth along the inner wall of the conveying track 4, so that the cleaning tube 14 blows away the dust and debris on the conveying track 4 to remove the dust. After the cleaning is completed, the first fixed block 10 and the second fixed block 11 are rotated to their original position through the rotating structure, and then the protective structure in the second fixed block 11 is started, and dry lubricant is applied to the inner wall of the conveying track 4 to reduce the friction between the O-ring 5 and the conveying track 4, prevent the conveying track 4 from getting stuck, thereby improving the efficiency of the conveying and facilitating assembly and testing.

[0023] like Figures 4 to 9 As shown, the protective structure includes an electric push rod 15, a scraper 16, a connecting plate 17, a first rack 18, a gear 19, a movable rod, a second rack 20, a movable seat 21, a liquid storage tank 22 and a nozzle 23; The top of the electric push rod 15 is fixedly installed with the inner wall of the movable groove of the second fixed block 11, the bottom of the electric push rod 15 is fixedly installed with a scraper 16, the top of the scraper 16 is fixedly installed with a connecting plate 17, one side of the connecting plate 17 is fixedly installed with a first rack 18, one side of the first rack 18 is engaged with a gear 19, a movable rod is fixedly installed in the middle of the gear 19, both ends of the movable rod are rotatably connected to the movable groove, one side of the gear 19 is engaged with a second rack 20, the second rack 20 is fixedly installed with a movable seat 21, and the movable seat 21 is connected to the movable groove. The inner wall of the movable groove is slidably connected, a liquid storage tank 22 is fixedly installed on the top of the movable seat 21, and a nozzle 23 is fixedly installed on the bottom of the liquid storage tank 22. The bottom of the scraper 16 is in contact with the inner wall of the conveying track 4, and the scraper 16 is slidably connected to the inner wall of the movable groove on the side away from the first rack 18. Dry lubricant is provided inside the liquid storage tank 22. One end of the nozzle 23 passes through the movable seat 21 and extends to the bottom of the movable groove. A control valve is fixedly installed on one end of the nozzle 23. There are multiple nozzles 23, and they are distributed in a linear array at the bottom of the movable seat 21.

[0024] When the cleaning is completed, after the second fixed block 11 moves to its original position, the electric push rod 15 is first started to drive the scraper 16 to move into the movable groove. When the scraper 16 moves, it drives the connecting plate 17 and the first rack 18 to move, so that the gear 19 drives the movable rod to rotate along the inner wall of the movable groove. The second rack 20 engaged with the gear 19 drives the movable seat 21 to move downward, so that the liquid storage pipe and the nozzle 23 move toward the inner wall of the conveying track 4. When the scraper 16 moves into the movable groove, one end of the nozzle 23 moves to the bottom of the second fixed block 11, and the control valve is started to make the nozzle 23 on the inner wall of the liquid storage tank 22 spray dry lubricant, and is driven to rotate by the first motor 7. The action of the rod 8 and the moving block 9 enables the rotating structure to drive the second fixed block 11 to move back and forth along the inner wall of the conveying track 4, spraying the dry lubricant on the conveying track 4. After the spraying is completed, the electric push rod 15 drives the scraper 16 to move downward. Under the action of the first rack 18, the gear 19 and the second rack 20, the nozzle 23 moves into the movable groove, and the scraper 16 moves to the inner wall of the conveying track 4. When the second fixed block 11 drives the scraper 16 to move, the dry lubricant can be evenly applied. The dry lubricant is made of polytetrafluoroethylene and can form a film on the inner wall of the conveying track 4, reducing friction and adhesion, thereby improving the effect of assembly and testing.

[0025] like Figures 6 to 8 As shown, mounting openings 24 are provided on the top of the conveying track 4 and the top of the second fixed block 11 , and an elastic telescopic tube 25 is fixedly installed on the top of the liquid storage tank 22 , and the end of the elastic telescopic tube 25 away from the liquid storage tank 22 is located in the mounting opening 24 of the second fixed block 11 .

[0026] The installation port 24 and the elastic telescopic tube 25 facilitate the delivery of dry lubricant to the interior of the liquid storage tank 22. When the liquid storage tank 22 moves downward, the elastic telescopic tube 25 stretches, making it easier for the nozzle 23 to move to the inner wall of the conveying track 4 to spray the dry lubricant, thereby improving the protection effect of the conveying track 4, preventing the conveying track 4 from being damaged, and facilitating the improvement of the efficiency of conveying the O-ring 5.

[0027] like Figures 6 to 9 As shown, the rotating structure includes a mounting plate 26, a second motor 27, a rotating shaft and a fixing plate 28; Two mounting plates 26 are fixedly installed on the side of the moving block 9 close to the second fixed block 11, and a second motor 27 is fixed on one side of the upper mounting plate 26. The output end of the second motor 27 is fixedly connected to a rotating shaft, and the bottom of the rotating shaft is rotatably connected to the top of the mounting plate 26 located below. Fixed plates 28 are fixedly installed on the upper and lower ends of the rotating shaft, and one end of the fixed plate 28 is fixedly installed on the first fixed block 10. The second fixed block 11 is provided with a fixing groove on the side away from the moving block 9, and an electric telescopic rod 30 is fixedly installed in the fixing groove. A baffle 31 is fixedly installed on one end of the electric telescopic rod 30. The two mounting plates 26 are located on the upper and lower sides of the moving block 9, and one side of the two mounting plates 26 is slidably connected to the inner wall of the mounting groove. The fixed plate 28 is located on the upper and lower sides of the second fixed block 11, and elastic buffer pads 29 are fixedly connected on both sides of the first fixed block 10 and the second fixed block 11. The elastic buffer pads 29 are made of polyurethane.

[0028] By starting the second motor rotating shaft and the fixed plate 28 to rotate, the first fixed block 10 and the second fixed block 11 respectively rotate the inner wall of the conveying track 4, and the cleaning structure and the protective structure respectively perform cleaning and protection functions. When the O-ring 5 moves to the movable opening 12 of the conveying track 4, the electric telescopic rod 30 is started to drive the baffle 31 to move to the middle of the conveying track 4 to block the O-ring 5. The elastic buffer pad 29 absorbs the impact force during transportation to protect the O-ring 5 from collision damage. When the O-ring 5 on one side of the second fixed plate 28 moves to the end of the conveying track 4 for unloading, the electric telescopic rod 30 is started again to drive the baffle 31 to move into the installation groove, so that the subsequent O-ring 5 continues to move. The intermittent movement of the baffle 31 allows the O-rings 5 ​​to be unloaded one by one at the end of the conveying track 4, thereby preventing the O-rings 5 ​​from accumulating on the conveying track 4, avoiding excessive transportation and affecting the efficiency of assembly and testing.

[0029] Working principle: When in use, start the vibration plate 2 to transport the O-ring 5 to the connecting block 3 and the conveying track 4. When the O-ring 5 moves to the movable opening 12 of the conveying track 4, the electric telescopic rod 30 is started to drive the baffle 31 to move to the middle of the conveying track 4 to block the O-ring 5. The elastic buffer pad 29 absorbs the impact force during transportation to protect the O-ring 5 from collision damage. When the O-ring 5 on the side of the second fixed plate 28 moves to the end of the conveying track 4 for unloading, the electric telescopic rod 30 is started again to drive the baffle 31 to move to the installation groove, so that the subsequent O-rings 5 ​​continue to move to the end of the conveying track 4. The intermittent movement of the baffle 31 allows the O-rings 5 ​​to be unloaded one by one at the end of the conveying track 4, and the O-rings 5 ​​are transported to the designated workstation for assembly and inspection.

[0030] When dust is generated on the conveying track 4, the vibrating plate 2 is stopped from conveying the O-ring 5. When the O-ring 5 on the conveying track 4 is unloaded, the conveying track 4 is emptied, and the second motor 27 is started to drive the rotating shaft and the fixed plate 28 to rotate, so that the first fixed block 10 is rotated to the inner wall of the conveying track 4 and keeps it perpendicular to the conveying track 4, while the second fixed block 11 is rotated to the installation groove and keeps it parallel to the conveying track 4. The first motor 7 is started to drive the rotating rod 8 to rotate along the installation groove. Since the upper and lower sides of the moving block 9 are slidably connected to the inner wall of the installation groove, when the rotating rod 8 rotates The moving block 9 does not rotate. The moving block 9 drives the rotating structure, the first fixed block 10 and the second fixed block 11 to move back and forth along the rotating rod 8 in the installation groove, and starts the blower 13 at the same time. When the first fixed block 10 moves, it drives the blower 13 and the cleaning pipe 14 to move back and forth along the inner wall of the conveying track 4, so that the cleaning pipe 14 blows away the dust and debris on the conveying track 4 to remove the dust. After the cleaning is completed, the first fixed block 10 and the second fixed block 11 are rotated to their original positions through the rotating structure. When the cleaning is completed, after the second fixed block 11 moves to its original position, the electric push is started first. The rod 15 drives the scraper 16 to move into the movable groove. When the scraper 16 moves, it drives the connecting plate 17 and the first rack 18 to move, so that the gear 19 drives the rotating rod 8 to rotate along the inner wall of the movable groove. The second rack 20 engaged with the gear 19 drives the movable seat 21 to move downward, so that the liquid storage pipe and the nozzle 23 move toward the inner wall of the conveying track 4. When the scraper 16 moves into the movable groove, one end of the nozzle 23 moves to the bottom of the second fixed block 11, and the control valve is activated to make the nozzle 23 on the inner wall of the liquid storage tank 22 spray dry lubricant, and the rotating rod 8 and the movable block 9 are driven by the first motor 7. The rotating structure drives the second fixed block 11 to move back and forth along the inner wall of the conveying track 4 to spray the dry lubricant on the conveying track 4. After the spraying is completed, the electric push rod 15 drives the scraper 16 to move downward. Under the action of the first rack 18, the gear 19 and the second rack 20, the nozzle 23 moves into the movable groove, and the scraper 16 moves to the inner wall of the conveying track 4. The second fixed block 11 drives the scraper 16 to move so that the dry lubricant is evenly applied, and then the O-ring 5 is continued to be transported through the vibration plate 2, the connecting block 3 and the conveying track 4 for assembly and testing.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
