Appearance defects (such as surface scratches and structural deformations) and functional abnormalities (such as poor pressing and uneven spraying) of the medicine sprayers can lead to deviation in medicine dosage control or ineffective use. There are many deficiencies in existing detection technologies: on the one hand, manual detection relies on visual observation and manual pressing tests, with low detection efficiency, high labor intensity, and being easily affected by subjective factors, resulting in large errors in detection results; on the other hand, automated detection devices mostly adopt independent operations of single functional modules, such as only detecting the appearance through machine vision or testing the pressing function through simple mechanical structures, lacking an integrated design of clamping, detection, and sorting, and it is difficult to meet the multi-dimensional detection requirements of medicine sprayers. In addition, the compatibility of existing devices with sprayers of different specifications is poor, the clamping structure cannot be adjusted adaptively, and the flexibility of the sorting link is insufficient, unable to accurately match diverse production scenarios, resulting in a long detection process and low device versatility, seriously restricting the quality control and efficiency improvement of medicine sprayer production.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] In order to solve the problems in the background technology in the field of drug nozzle production and manufacturing, the quality of finished products is directly related to the safety and effectiveness of drug use. Appearance defects (such as surface scratches and structural deformation) and functional abnormalities (such as poor pressing and uneven spraying) can lead to drug dosage control deviation or use failure. There are many deficiencies in the existing detection technologies: on the one hand, manual detection relies on visual observation and manual pressing tests, with low detection efficiency, high labor intensity, and is easily affected by subjective factors, resulting in large errors in detection results; on the other hand, automated detection equipment mostly uses single-function modules to operate independently, such as only detecting the appearance through machine vision or testing the pressing function through a simple mechanical structure, lacking an integrated design of clamping, detection, and sorting, and it is difficult to meet the multi-dimensional detection requirements of drug nozzles. In addition, the compatibility of existing equipment with different specifications of nozzles is poor, the clamping structure cannot be adjusted adaptively, and the flexibility of the sorting link is insufficient, unable to accurately match diverse production scenarios, resulting in a long detection process and low equipment versatility, seriously restricting the quality control and efficiency improvement of drug nozzle production, the present invention provides, as Figures 1 - 9 shown, a rapid detection and screening device for defects in drug nozzle finished products, including a main body 1. A box body 2 is arranged in the inner cavity of the main body 1. A first servo motor 21 is connected to the inner cavity of the box body 2 by bolts. A rotating rod 22 is fixedly connected to the power output end of the first servo motor 21. A sleeve 24 is slidably arranged on the top of the rotating rod 22. A clamping mechanism is arranged inside the sleeve 24. A turbine 23 is rotatably connected to the inner cavity of the box body 2. A cam 231 is arranged on the outer side wall of the turbine 23. A circular plate 232 is arranged on the side of the cam 231 away from the turbine 23. A thread 221 is arranged on the outer side wall of the rotating rod 22. The thread 221 is engaged with the turbine 23. By starting the first servo motor 21, the first servo motor 21 rotates to drive the rotating rod 22 to rotate. During the rotation of the rotating rod 22, the thread 221 is driven to rotate. During the rotation of the thread 221, the turbine 23 is driven to rotate;

[0035] The sleeve 24 is connected to a support plate 25 through a bearing. During the rotation of the turbine 23, the cam 231 is driven to rotate, thereby driving the support plate 25 to move up and down. Slide bars 251 are uniformly fixedly connected to the outer side wall of the support plate 25. Limiting grooves 201 are uniformly dug in the inner cavity of the box body 2. The slide bars 251 are slidably connected in the limiting grooves 201. The position of the support plate 25 is limited by the cooperation of the slide bars 251 and the limiting grooves 201. During the limiting of the support plate 25, the position of the rotating rod 22 is limited. A connecting rod 252 is arranged at the bottom of the support plate 25. A roller 253 is rotatably connected to the bottom of the connecting rod 252. The roller 253 is located on the top of the cam 231. Through the cooperation of the roller 253 and the cam 231, the cam 231 rotates to drive the roller 253 to move up and down. The setting of the circular plate 232 facilitates the limiting of the roller 253. A lifting clamping assembly is arranged on the top of the main body 1.

[0036] During specific use, first, the main body 1 is fixed to the corresponding position by bolts. By starting the first servo motor 21, the first servo motor 21 rotates to drive the rotating rod 22 to rotate. During the rotation of the rotating rod 22, the thread 221 is driven to rotate. During the rotation of the thread 221, the turbine 23 is driven to rotate. During the rotation of the turbine 23, the cam 231 is driven to rotate, thereby driving the support plate 25 to move up and down. The position of the support plate 25 is limited by the cooperation of the sliding rod 251 and the limiting groove 201. During the limiting process of the support plate 25, the position of the rotating rod 22 is limited. During the up and down movement of the support plate 25, the sleeve 24 is driven to move up and down.

[0037] Furthermore, a spring 222 is arranged in the inner cavity of the rotating rod 22. A limiting disc 223 is arranged at the top of the spring 222. An acting rod 248 is fixedly arranged at the top of the limiting disc 223. A sliding groove 224 is dug in the inner cavity of the rotating rod 22. A sliding block 241 is arranged on the outer side wall of the sleeve 24. The sliding block 241 is located in the inner cavity of the sliding groove 224. Through the cooperation between the sliding block 241 and the sliding groove 224, the sleeve 24 can move up and down during rotation. Connecting grooves 242 are dug on both sides of the top of the sleeve 24. A rotating shaft 243 is rotatably connected in the inner cavity of the connecting groove 242. When the V-shaped elastic rod 244 moves up and down, the friction is reduced through the setting of the rotating shaft 243. The clamping mechanism includes the V-shaped elastic rod 244. The V-shaped elastic rod 244 is located in the inner cavity of the sleeve 24. The V-shaped elastic rod 244 is located on the opposite side of the two rotating shafts 243. The top of the acting rod 248 penetrates through the sleeve 24 and is connected to the bottom of the V-shaped elastic rod 244. T-shaped connecting blocks 245 are arranged on both sides of the top of the V-shaped elastic rod 244. An arc-shaped clamping head 246 is connected to the top of the T-shaped connecting block 245. The arc-shaped clamping head 246 is made of transparent glass material or transparent polyethylene material. A T-shaped sliding groove matching the T-shaped connecting block 245 is dug at the bottom of the arc-shaped clamping head 246. The settings of the T-shaped connecting block 245 and the T-shaped sliding groove facilitate the disassembly of the arc-shaped clamping head 246. A fastening bolt 247 is arranged on the outer side wall of the arc-shaped clamping head 246. The setting of the fastening bolt 247 facilitates the fixing of the arc-shaped clamping head 246. A wide-angle camera 11 and a turntable 12 are respectively arranged at the top of the inner cavity of the main body 1. The turntable 12 and the sleeve 24 are located on the same horizontal plane.

[0038] During operation, the sleeve 24 is driven to move up and down by the support plate 25 moving up and down. The sleeve 24 drives the V-shaped elastic rod 244 to move upward during the rising process. The V-shaped elastic rod 244 drives the limit plate 223 to move upward during the upward movement. Under the pulling force of the spring 222, the V-shaped elastic rod 244 is forced to move toward the inside of the sleeve 24, so that the elastic rods on both sides of the V-shaped elastic rod 244 are closed inward, driving the two sets of arc-shaped clamps 246 to close inward to clamp the finished drug spray head and move upward. After being clamped, the finished drug spray head rotates and moves upward. When the finished drug nozzle continues to move upward and collides with the turntable 12, the pressing nozzle on the finished drug nozzle shrinks. When the support plate 25 moves downward, the pressing nozzle on the finished drug nozzle shrinks, and the wide-angle camera 11 quickly detects and analyzes the finished drug nozzle that moves upward and downward. When the sleeve 24 descends, the V-shaped elastic rod 244 is driven to move downward. When the V-shaped elastic rod 244 descends to a certain position, under the thrust of the spring 222 and the limit plate 223, the V-shaped elastic rod 244 is drawn out of the sleeve 24, and the two groups of arc-shaped clamps 246 open outward.

[0039] Furthermore, the lifting and clamping assembly includes a fixing plate 3, which is connected to the top of the body 1. The inner cavity of the fixing plate 3 is connected to the cylinder 31 by bolts, so that the cylinder 31 is fixed. The power output end of the cylinder 31 is connected to the action plate 32. The inner cavity of the action plate 32 is provided with a lifting rod 33. The inner cavity of the action plate 32 is connected to the lifting rod 33 through a bearing, so as to ensure that the lifting rod 33 can rotate during the up and down movement. The bottom of the lifting rod 33 is provided with an electric claw 34. The setting of the electric claw 34 facilitates the clamping of the finished drug spray head. The fixing plate 3 The inner cavity is rotatably connected to the first gear 35, and the inner cavity of the first gear 35 is grooved with a circular through hole, the lifting rod 33 is located in the circular through hole, and limited connection grooves are grooved on both sides of the circular through hole. The outer wall of the lifting rod 33 is provided with a limit connecting block, and the limit connecting groove is adapted to the limit connecting block. The inner cavity of the fixed plate 3 is connected to the second servo motor 36 by bolts, and the power output end of the second servo motor 36 is connected to the second gear 37, and the second gear 37 is matched with the first gear 35, so that the electric claw 34 can not only move up and down, but also can realize 360 ​​degree rotation to adjust the position.

[0040] During specific use, by starting the cylinder 31, the cylinder 31 drives the action plate 32 to move up and down. During the up and down movement of the action plate 32, the lifting rod 33 is driven to move up and down. By starting the second servo motor 36, during the rotation of the second servo motor 36, the second gear 37 is driven to rotate. During the rotation of the second gear 37, the first gear 35 is driven to rotate. During the rotation of the first gear 35, the lifting rod 33 is driven to rotate. During the rotation of the lifting rod 33, the electric claw 34 is driven to not only move up and down, but also rotate 360 degrees to adjust the position.

[0041] Working principle: After the equipment is started, first, the main body 1 is firmly installed at the specified position through bolts. The first servo motor 21 is started, and its power output drives the rotating rod 22 to rotate. The thread 221 on the surface of the rotating rod 22 meshes with the turbine 23, transmitting the rotational motion to the turbine 23. When the turbine 23 rotates, the cam 231 on it rotates accordingly. By contacting the roller 253 at the bottom of the support plate 25, the support plate 25 is pushed to move up and down linearly along the limit groove 201 in the inner cavity of the box body 2. The cooperation between the sliding rod 251 and the limit groove 201 not only restricts the movement track of the support plate 25, but also plays a limiting role on the rotating rod 22 through the support plate 25, ensuring the transmission stability. The up and down movement of the support plate 25 drives the sleeve 24 connected to it to move synchronously. When the sleeve 24 rises, the V-shaped elastic rod 244 inside it moves upward accordingly. The V-shaped elastic rod 244 pushes the limit disk 223 to compress the spring 222 in the rotating rod 22. As it rises, under the pulling force of the spring 222, the V-shaped elastic rod 244 contracts into the sleeve 24, and the elastic rods on both sides drive the arc-shaped clamping head 246 to close inward, precisely clamping the finished product of the drug spray head. After clamping the spray head, the rotation of the rotating rod 22 drives the spray head to move upward and rotate. When the spray head touches the turntable 12, the pressing spray head is triggered to contract. At this time, the wide-angle camera 11 performs all-round image acquisition on the spray head during the rotation and rising and falling processes in the high-speed continuous shooting mode to analyze the appearance and pressing function defects. After the detection is completed, the sleeve 24 descends, the V-shaped elastic rod 244 loses the support of the limit disk 223, and slides out of the sleeve 24 under the thrust of the spring 222, and the arc-shaped clamping head 246 opens outward to release the spray head. At the same time, the cylinder 31 is started to drive the action plate 32 to move up and down, thereby driving the lifting rod 33 to move vertically; the second servo motor 36 is started, and through the meshing transmission of the second gear 37 and the first gear 35, the lifting rod 33 drives the electric claw 34 to rotate 360 degrees. The electric claw 34 flexibly adjusts the position to grab the spray head according to the detection result, sorting the qualified products and unqualified products into different areas, and completing the entire detection and screening process.
