By starting the third electric guide rail 24, the first clamping cylinder 27 is driven to move upward. When the finished drug nozzle is separated from the conveying device, by starting the first flipping cylinder 25, the first clamping cylinder 27 is driven to rotate 360 degrees. Then, it is detected by the detection device. After the first clamping cylinder 27 drives the finished drug nozzle to complete the detection, the position of the first clamping cylinder 27 is adjusted by the third electric guide rail 24, so that the second clamping cylinder 31 clamps the connection part between the finished drug nozzle and the bottle cap. After the second clamping cylinder 31 completes the clamping, the first clamping cylinder 27 moves upward. By the second flipping cylinder 3, the second clamping cylinder 31 is driven to rotate 360 degrees for re-detection by the detection device. After the detection is completed, the first clamping cylinder 27 is closed. The first clamping cylinder 27 is driven to move up and down by the third electric guide rail 24, so that the second chuck 29 presses down on the drug nozzle. The detection device detects whether the drug nozzle will reset after being pressed down. By the first electric guide rail 201, the fixed plate 2 is driven to move horizontally, and the input end of the finished drug nozzle can be placed into the liquid. By the third electric guide rail 24, the first clamping cylinder 27 is driven to move up and down multiple times to detect the spraying condition of the medicine mist nozzle; Further, the first clamping mechanism includes a first flipping cylinder 25, the first flipping cylinder 25 is connected to the top of the mounting plate 26, the power output end of the first flipping cylinder 25 penetrates through the mounting plate 26 and is connected with a first clamping cylinder 27, the power output end of the first clamping cylinder 27 is provided with a first chuck 28, and the outer side wall of the first chuck 28 is provided with a second chuck 29; During specific operation, for the first clamping mechanism: according to the posture of the finished product of the drug nozzle, the first flipping cylinder 25 is ventilated to drive the first clamping cylinder 27 to perform angular flipping and adjust to a suitable clamping angle. Subsequently, the first clamping cylinder 27 is ventilated to start, and its power output end pushes the first chuck 28 and the second chuck 29 to move relatively, closing to clamp a certain part of the finished product of the drug nozzle. For example, when the finished product of the drug nozzle is in an inclined state, the first flipping cylinder 25 can flip the first clamping cylinder 27 to an angle perpendicular to the surface of the finished product of the drug nozzle and then perform clamping; The second clamping mechanism includes a second flipping cylinder 3, the second flipping cylinder 3 is connected to the outer side wall of the fixing plate 2, the power output end of the second flipping cylinder 3 penetrates through the fixing plate 2 and is connected with a second clamping cylinder 31, the power output end of the second clamping cylinder 31 is connected with a chuck arm 32, a plug-in slot 321 is drilled in the inner cavity of the chuck arm 32, a plug-in rod 331 is connected to the inner cavity of the plug-in slot 321, the end of the plug-in rod 331 far away from the plug-in slot 321 is connected with a third chuck 33, a mounting hole is drilled in the outer side wall of the chuck arm 32, a threaded hole is drilled in the inner cavity of the plug-in rod 331, and the mounting hole and the threaded hole are connected by bolts; During specific operation, for the second clamping mechanism: according to the detection requirement, the second flipping cylinder 3 is ventilated to drive the second clamping cylinder 31 to perform angular flipping and adjust the clamping posture. Then, the second clamping cylinder 31 is ventilated to work, and its power output end pushes the chuck arm 32 and the connected third chuck 33 to act and clamp another part of the finished product of the drug nozzle. If the specification of the finished product of the drug nozzle changes, the bolt between the chuck arm 32 and the plug-in rod 331 can be disassembled to replace the adapted third chuck 33; Working principle: Device installation: The mounting base 13 at the bottom of the support arm 1 is firmly installed on a flat and sufficiently load-bearing working ground through the connection holes at the four corners using bolts and other connecting parts, ensuring that the support arm 1 is perpendicular to the ground to provide stable basic support for the entire device; Electrical connection: Connect the servo motor 11, first electric guide rail 201, second electric guide rail 22, third electric guide rail 24, first flip cylinder 25, first clamping cylinder 27, second flip cylinder 3, second clamping cylinder 31 and other electrical components to the supporting electrical control cabinet or power supply system according to their respective electrical interfaces and specifications, and take safety measures such as grounding. At the same time, connect the detection equipment such as high-definition industrial cameras and sensors used to detect defects in the finished drug nozzle and the line between the control system to ensure normal signal transmission; Parameter setting: On the control system operation interface such as a touch screen or an industrial computer operation interface, according to the specifications and model of the finished drug spray nozzle to be tested, pre-set the parameters such as the rotation speed and angle range of the servo motor 11, the moving stroke and speed of each electric guide rail, and the clamping force of the clamping mechanism; 2. Inspection of finished drug spray nozzles Automatic loading: The finished drug spray nozzles to be tested are transported to the vicinity of the device through a vibrating plate; The first clamping cylinder 27 drives the first clamping head 28 to grab the finished drug spray head, and the first clamping cylinder 27 is driven to move upward by starting the third electric guide rail 24. When the finished drug spray head leaves the conveying device, the first flipping cylinder 25 is started to drive the first clamping cylinder 27 to rotate 360 degrees, and then it is inspected by the inspection equipment. After the first clamping cylinder 27 drives the finished drug spray head to complete the inspection, the position of the first clamping cylinder 27 is adjusted by the third electric guide rail 24, so that the second clamping cylinder 31 clamps the finished drug spray head and the bottle cover. After the second clamping cylinder 31 completes the clamping, the first clamping cylinder 27 moves upward, and the second flipping cylinder 3 drives the second clamping cylinder 27 to rotate 360 degrees. The cylinder 31 rotates 360 degrees and is tested again by the detection equipment. After the test is completed, the first clamping cylinder 27 is closed and the first clamping cylinder 27 is driven to move up and down by the third electric guide rail 24, so that the second clamping head 29 presses down on the medicine spray nozzle. The second clamping head 29 is made of rubber and plays a buffering role for the medicine spray nozzle when pressing down. The detection equipment detects whether the medicine spray nozzle will reset after being pressed down. The first electric guide rail 201 drives the fixed plate 2 to move horizontally, so that the finished product input end of the medicine spray nozzle can be placed in the liquid. The third electric guide rail 24 drives the first clamping cylinder 27 to move up and down multiple times to detect the spraying situation of the medicine mist spray nozzle. 3. Testing process Rotation of the rotating frame: The device is started, the servo motor 11 is powered on, and its power output end drives the rotating frame 12 to rotate around the central axis of the top of the support arm 1. The rotation speed and angle are based on pre-set parameters, for example, 360 degrees clockwise at a speed of 5 rpm; Electric guide rail adjustment position: The first motorized guide rail 201 moves along the radial direction of the rotating frame 12 on the first slide rail 122 according to a preset program or inspection requirements, driving the fixed plate 2 to move closer to or away from the finished drug spray nozzle product. For example, when inspecting parts of different diameters of the finished drug spray nozzle product, the first motorized guide rail 201 can accurately adjust the distance to bring the inspection component closer to the target grasping area; The second electric guide rail 22 and the third electric guide rail 24 work in coordination. The second electric guide rail 22 enables the third electric guide rail 24 to move along the second slide rail 23, further accurately adjusting the inspection position. For example, when inspecting the side details of a finished drug spray nozzle, the cooperation of these two electric guide rails can move the first clamping mechanism and related inspection components to the appropriate height and horizontal position. Clamping mechanism action: First clamping mechanism: The first turning cylinder 25 drives the first clamping cylinder 27 to turn the angle according to the posture of the finished drug spray nozzle, adjusting it to a suitable clamping angle. Subsequently, the first clamping cylinder 27 is ventilated and activated, and its power output end pushes the first clamping head 28 and the second clamping head 29 to move relative to each other, closing and clamping a certain part of the finished drug spray nozzle. For example, when the finished drug spray nozzle is in a tilted state, the first turning cylinder 25 can turn the first clamping cylinder 27 to an angle perpendicular to the surface of the finished drug spray nozzle, and then clamp it; Second clamping mechanism: The second turning cylinder 3 is ventilated to drive the second clamping cylinder 31 to rotate the angle according to the detection requirements to adjust the clamping posture. Then, the second clamping cylinder 31 is ventilated to work, and its power output end pushes the clamping arm 32 and the connected third clamping head 33 to move and clamp another part of the finished drug spray nozzle. If the specifications of the finished drug spray nozzle are changed, the bolts between the clamping arm 32 and the plug rod 331 can be removed to replace the appropriate third clamping head 33; Defect detection: After the clamping mechanism clamps the finished drug nozzle, the device drives the finished drug nozzle to rotate and move. At the same time, detection equipment installed in a suitable position, such as a high-definition industrial camera, takes photos of the finished drug nozzle appearance. Sensors detect parameters such as nozzle aperture and nozzle shape to conduct a comprehensive defect screening of the finished drug nozzle. The detection equipment transmits the collected data to the control system in real time. The control system analyzes and processes the data using preset algorithms and standards to determine whether the finished drug nozzle has defects, such as surface scratches, aperture deviation, nozzle blockage, etc. 4. Test result processing Qualified product processing: If the test results determine that the finished drug spray nozzle is qualified, the clamping mechanism of the device is released, and the finished drug spray nozzle is moved to the qualified product storage area by manual or automatic unloading robot arm; Treatment of non-conforming products: If the test result determines that there are defects in the finished product of the drug nozzle, the device will automatically trigger an alarm prompt such as a buzzer alarm and an indicator light flashing. At the same time, the control system records the relevant information of the non-conforming product, such as the defect type, location, and detection time. Then, the clamping mechanism transports the non-conforming product to the storage area for non-conforming products for subsequent rework or scrapping.
