Description

Technical Field

[0001] This invention belongs to the field of light inspection machine technology, and more specifically, relates to a fully automatic light inspection machine for cartridge bottles. Background Technology

[0002] Cartridge vials are a new type of pharmaceutical packaging container made of borosilicate glass or medical-grade plastic. They typically consist of a vial body, a rubber piston, and an aluminum cap. Their core design allows for precise dosage delivery of medications when used with specialized injection pens. As an important form of modern pharmaceutical packaging, cartridge vials are widely used in the fields of biologics, insulin, vaccines, and ophthalmic medications due to their excellent sealing properties, corrosion resistance, and portability.

[0003] Currently, the light inspection of cartridge vials is a crucial step in pharmaceutical quality control. Its core objective is to detect the presence of visible foreign objects, bottle cracks, sealing defects, and other issues. A typical light inspection process includes: first, manually placing the vials into the inspection station to ensure a stable inspection posture; then, using a high-brightness LED light source to illuminate the bottle from the side or bottom, creating a light scattering effect to facilitate the identification of foreign objects; next, using an industrial camera to capture images of the bottle's interior from multiple angles, and combining this with algorithms to identify the shape, size, and location of any foreign objects; finally, based on the inspection results, qualified and unqualified vials are separated and transported separately, with the unqualified vials proceeding to a rejection mechanism.

[0004] However, some medications contained in existing cartridge vials, such as insulin suspensions and traditional Chinese medicine injections, are prone to precipitation. Precipitates and foreign objects are visually very similar, making it difficult for traditional detection methods to distinguish them effectively. In addition, cartridge vials are prone to generating air bubbles during transport due to shaking and collisions. These air bubbles can obstruct the field of view or be misjudged as foreign objects, interfering with the accuracy of the detection and making it difficult to guarantee the stability of the detection results. Summary of the Invention

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A fully automatic light inspection machine for cartridge bottles is provided, comprising a machine body, and a bottle feeding assembly and a quality inspection assembly sequentially arranged on the machine body; the bottle feeding assembly is used to convey cartridge bottles in a vertical position, and the quality inspection assembly is used to inspect the cartridge bottles; the fully automatic light inspection machine further includes: A pre-rotation assembly is disposed on the machine body and located between the bottle inlet assembly and the quality inspection assembly; the pre-rotation assembly is used to receive multiple vertically positioned cartridge bottles conveyed by the bottle inlet assembly and to drive each cartridge bottle to rotate at high speed to eliminate sedimentation and air bubbles in the liquid inside the cartridge bottle; and A transition conveying mechanism is disposed between the pre-swirl assembly and the quality inspection assembly, for conveying the cartridge bottle, after the pre-swirl assembly has eliminated sediment and air bubbles, to the quality inspection assembly, thereby facilitating the quality inspection assembly to inspect the liquid inside the cartridge bottle.

[0013] In one possible implementation, the rotary inspection mechanism includes: The quality inspection turntable is vertically connected to the machine body and is driven by a sixth motor to rotate the quality inspection turntable. Multiple second spin members are circumferentially spaced on the quality inspection turntable. These second spin members receive cartridge bottles after inspection by the accessory inspection mechanism, thereby causing the cartridge bottles to rotate around their own axes. Multiple light inspection units surround the outer periphery of the quality inspection turntable, each used to inspect the appearance and contents of the cartridges on each of the second spin components.

[0014] In one possible implementation, the second spin member includes: The second rotating seat is rotatably connected to the quality inspection turntable in a vertical direction, and is driven by a seventh motor to rotate the second rotating seat; the second rotating seat is used to connect with the lower end of the cartridge bottle; and The second clamping seat is located on the upper side of the second rotating seat and is coaxially arranged with the second rotating seat; the second clamping seat is slidably connected to the quality inspection turntable in the vertical direction, and a second pressing member is provided between the second clamping seat and the quality inspection turntable.

The outer circumference of the second detection star wheel has multiple spaced-apart second detection grooves, each used to receive a cartridge bottle after it has been inspected by the rotary inspection mechanism. The second detection star wheel is driven by an eighth motor to rotate it. The second detection unit is located outside the second detection star wheel and is used to detect the bottom of the cartridge bottle in each of the second detection grooves.

[0016] In this embodiment, the bottle feeding assembly transports multiple vertically positioned cartridge bottles to the corresponding station of the pre-spinning assembly in an orderly manner according to a preset rhythm, ensuring the stability of the cartridge bottles and providing a foundation for subsequent processing. After receiving the cartridge bottles, the pre-spinning assembly fixes the bottle body using a clamping or positioning mechanism, driving each cartridge bottle to rotate at high speed. Centrifugal force is used to evenly disperse the precipitate in the liquid within the bottle, while simultaneously quickly dispersing air bubbles to the surface of the liquid or the top space of the bottle, completely eliminating interference from precipitate and air bubbles for subsequent testing. The transition conveying mechanism steadily transports the pre-spinned cartridge bottles, maintaining their vertical orientation, to the quality inspection assembly. A low-vibration design is used during transport to prevent the liquid from shaking and generating air bubbles again, ensuring the stability of the liquid. The quality inspection assembly performs multi-dimensional inspection on the pre-spinned cartridge bottles.

At the same time, the fully automated connection of the entire process improves the detection efficiency compared with traditional equipment, adapting to the needs of large-scale production. Each link maintains the vertical posture of the cartridge bottle and adopts a low-vibration conveying design, effectively avoiding the generation of air bubbles again due to liquid shaking, ensuring the stability of the detection results. Moreover, the modular structure allows for flexible adjustment of parameters, compatible with the detection needs of different specifications of cartridge bottles and various types of liquids, making it more widely applicable.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Please refer to the following: Figures 1 to 6The fully automatic light inspection machine for cartridge bottles provided in this application will now be described. The fully automatic light inspection machine for cartridge bottles includes a machine body 1, a bottle feeding assembly 4 for conveying cartridge bottles in a vertical position, and a quality inspection assembly for inspecting the cartridge bottles; the fully automatic light inspection machine also includes a pre-rotation assembly and a transition conveying mechanism 5.

[0025] The pre-rotation component is installed on the machine body 1 and is located between the bottle inlet component 4 and the quality inspection component. The pre-rotation component is used to receive multiple vertically positioned cartridge bottles conveyed by the bottle inlet component 4 and drive each cartridge bottle to rotate at high speed to eliminate sedimentation and air bubbles in the liquid inside the cartridge bottle.

[0026] The transition conveying mechanism 5 is located between the pre-swirl assembly and the quality inspection assembly. It is used to convey the cartridge bottle, which has been depreciated and bubble-free by the pre-swirl assembly, to the quality inspection assembly, so that the quality inspection assembly can test the liquid inside the cartridge bottle.

[0027] Bottle feeding assembly 4 transports vertically positioned cartridge bottles in batches to the inlet of the pre-rotation assembly; the pre-rotation assembly receives the cartridge bottles and drives them to rotate at high speed to eliminate drug sedimentation and air bubbles; the transition conveying mechanism 5 smoothly transports the pre-rotated cartridge bottles to the quality inspection assembly station; the quality inspection assembly conducts a comprehensive inspection of the appearance and contents of the cartridge bottles, completing the light inspection process.

[0028] By adding a pre-rotation component at the bottle entry and quality inspection stages, the centrifugal force and fluid disturbance of the high-speed rotation of the cartridge bottle are used to break the static equilibrium of the drug solution precipitation, so that the precipitate is uniformly suspended and the bubbles rise quickly; the transition conveying mechanism 5 serves as a buffer connection unit to prevent the cartridge bottle from generating precipitation or bubbles again due to the bumps during transportation, ensuring that the drug solution is in a uniform and stable state during quality inspection, thereby reducing detection errors from the source.

[0029] In this embodiment, the bottle feeding assembly 4 transports multiple vertically positioned cartridge bottles to the corresponding station of the pre-spinning assembly in an orderly manner according to a preset rhythm, ensuring the stability of the cartridge bottles and providing a foundation for subsequent processing. After receiving the cartridge bottles, the pre-spinning assembly fixes the bottle body through a clamping or positioning mechanism, driving each cartridge bottle to rotate at high speed. Centrifugal force is used to evenly disperse the precipitate in the liquid into the liquid, while simultaneously quickly driving air bubbles away to the surface of the liquid or the top space of the bottle, completely eliminating the interference of precipitate and air bubbles on subsequent testing. The transition conveying mechanism 5 steadily transports the pre-spinned cartridge bottles to the quality inspection assembly while maintaining a vertical posture. A low-vibration design is used during the transport process to prevent the liquid from shaking and generating air bubbles again, ensuring the stability of the liquid. The quality inspection assembly performs multi-dimensional testing on the pre-spinned cartridge bottles. At this point, the precipitate in the liquid is evenly dispersed, and the air bubbles have been removed, allowing for clear identification of visible foreign objects, bottle cracks, sealing defects, and other problems, achieving accurate testing.

[0030] The fully automatic light inspection machine for cartridge bottles provided in this application, compared with the prior art, fundamentally solves the industry pain points of difficulty in distinguishing between sediment and foreign matter in cartridge bottle liquids and interference from air bubbles through the pre-spinning component, significantly improving the detection accuracy. At the same time, the fully automated connection of the entire process improves the detection efficiency compared with traditional equipment, adapting to the needs of large-scale production. Each link maintains the vertical posture of the cartridge bottle and adopts a low-vibration conveying design, effectively avoiding the generation of air bubbles again due to liquid shaking, ensuring the stability of the detection results. Moreover, the modular structure allows for flexible adjustment of parameters, compatible with the detection needs of different specifications of cartridge bottles and various types of liquids, making it more widely applicable.

[0031] Further, please refer to Figures 1 to 6 As a specific embodiment of the fully automatic light inspection machine for cartridge bottles provided by the present invention, the pre-spinning assembly includes a pre-spinning working turntable 2 and a plurality of first optional components.

[0032] The pre-rotating turntable 2 is vertically connected to the machine body 1, and the pre-rotating turntable 2 is driven by a first motor to rotate.

[0033] Multiple first spin components 3 are arranged at circumferential intervals on the pre-spinning working turntable 2. The first spin components 3 are used to receive the vertically positioned cartridge bottles conveyed by the bottle feeding assembly 4, so as to drive the cartridge bottles to rotate around their own axis, thereby eliminating sediment and air bubbles inside the cartridge bottles.

[0034] The first motor drives the pre-spinning turntable 2 to rotate at a constant speed, causing the circumferentially distributed first spin member 3 to move cyclically; the first spin member 3 moves to the bottle inlet station to receive the cartridge bottles conveyed by the bottle inlet assembly 4; the first spin member 3 drives the cartridge bottles to rotate at high speed for a preset time to eliminate drug sedimentation and air bubbles; the pre-spinning turntable 2 conveys the pre-spinned cartridge bottles to the transition station, while the next spin member receives the new bottles, realizing continuous batch processing.

[0035] The system employs a combined revolution and rotation motion mode: the revolution of the pre-rotating working turntable 2 enables the circulation of the cartridge bottles, ensuring batch processing efficiency; each first spin component 3 independently drives the rotation of the cartridge bottle, precisely controlling the rotation speed and time to ensure consistent homogenization of the liquid in each bottle.

[0036] By adopting the above technical solutions, the rotary table can achieve continuous pre-rotation in a cyclical operation, which can be adapted to high-speed production lines. The independent rotation control can ensure that the homogenization effect of each bottle of medicine is consistent, and the circumferential layout can make full use of space, resulting in a small equipment footprint.

[0037] Further, please refer to Figures 1 to 6 As a specific embodiment of the fully automatic light inspection machine for cartridge bottles provided by the present invention, the first spin member 3 includes a first rotating seat 31 and a first pressing seat 32.

[0038] The first rotating seat 31 is rotatably connected to the pre-rotating working turntable 2 in the vertical direction, and is driven by a second motor to drive the first rotating seat 31 to rotate; the first rotating seat 31 is used to connect with the lower end of the cartridge bottle.

[0039] The first pressing seat 32 is located on the upper side of the first rotating seat 31 and is coaxially arranged with the first rotating seat 31. The first pressing seat 32 is slidably connected to the pre-rotating working turntable 2 in the vertical direction, and a first pressing member 33 is provided between the first pressing seat 32 and the pre-rotating working turntable 2. The power output end of the first pressing member 33 is rotatably connected to the first pressing seat 32 to drive the first pressing seat 32 to move toward or away from the first rotating seat 31. The first pressing seat 32 is used to connect with the upper end of the cartridge bottle.

[0040] When the cartridge bottle is conveyed between the first rotating seat 31 and the first pressing seat 32, the first pressing member 33 is adapted to drive the first pressing seat 32 to move toward the first rotating seat 31 to clamp the cartridge bottle; when the first rotating seat 31 rotates, it is adapted to drive the cartridge bottle to rotate around its own axis.

[0041] The first pressing component 33 can adopt a cam structure, an eccentric wheel structure, or a telescopic cylinder to drive the first pressing seat 32 to move upward or downward.

[0042] The stability of the rotation is ensured by coaxial upper and lower clamping and active rotation: the first rotating seat 31 and the first pressing seat 32 are coaxially set to avoid eccentric shaking when the cartridge bottle rotates; the first pressing component 33 provides adjustable clamping force, which ensures sufficient friction to drive the rotation without damaging the bottle body; the second motor directly drives the first rotating seat 31, which has high power transmission efficiency and precise controllable speed.

[0043] By adopting the above technical solutions, coaxial clamping is used to avoid eccentricity, which can ensure that the medicine liquid is uniformly homogenized; the clamping force can be adjusted and the clamping head can be replaced to adapt to multiple bottle sizes; automated and precise control reduces human intervention and lowers the risk of bottle damage.

[0044] Further, please refer to Figures 1 to 6 As a specific embodiment of the fully automatic light inspection machine for cartridge bottles provided by the present invention, the bottle feeding assembly 4 includes multiple conveying rollers 41, a bottle feeding screw 42, and a bottle feeding star wheel 43.

[0045] Multiple parallel conveyor rollers 41 are spaced apart on the upper side of the machine body 1; a mesh belt 44 connected end to end is fitted around the outer periphery of the multiple conveyor rollers 41, and one of the conveyor rollers 41 is connected to a third motor; when the third motor drives the conveyor roller 41 to rotate, it can drive the mesh belt 44 to move around the outer periphery of the multiple conveyor rollers 41; the mesh belt 44 is used to store and convey multiple cartridge bottles.

[0046] The bottle inlet screw 42 is rotatably connected to the machine body 1, and the axial direction of the bottle inlet screw 42 is parallel to the axial direction of the conveying roller 41; part of the bottle inlet screw 42 is located at the output port of the mesh belt 44 to receive several card bottles conveyed by the mesh belt 44, and the bottle inlet screw 42 can convey several card bottles in sequence at a certain pitch.

[0047] The bottle inlet star wheel 43 is rotatably connected to the machine body 1 in a vertical direction. The outer periphery of the bottle inlet star wheel 43 is provided with a plurality of spaced bottle inlet grooves 431. Each bottle inlet groove 431 is used to receive the cartridge bottle conveyed by the bottle inlet screw 42. The bottle inlet star wheel 43 is drivenly connected to the first motor to drive the bottle inlet star wheel 43 to rotate. The rotation direction of the bottle inlet star wheel 43 is opposite to the rotation direction of the pre-rotation working turntable.

[0048] When the bottle inlet star wheel 43 rotates, the bottle inlet groove 431 is adapted to correspond to one of the first spin members 3, so that the cartridge bottle in each bottle inlet groove 431 is transferred to the first spin member 3.

[0049] The mesh belt 44 carries multiple cartridge bottles. The third motor drives the conveyor roller 41 to move the mesh belt 44 horizontally, conveying the bottles to the bottle inlet screw 42. The bottle inlet screw 42 rotates, separating the dense cartridge bottles into single bottles according to a preset pitch. The bottle inlet star wheel 43 rotates, and the bottle inlet groove 431 receives the separated cartridge bottles and transfers them to the spin component station of the pre-spinning assembly.

[0050] It adopts a three-level mode of batch storage, fixed-distance bottle separation and precise positioning: the mesh belt 44 realizes large-capacity continuous conveying, the bottle inlet screw 42 controls the bottle separation distance through the spiral groove pitch to avoid congestion; the bottle inlet groove 431 of the bottle inlet star wheel 43 is precisely aligned with the pre-rotation station to ensure smooth transfer of the bottle body and realize the automation and orderliness of the bottle inlet process.

[0051] By adopting the above technical solution, the mesh belt 44 batch conveyor, combined with the screw bottle separator, achieves high-speed continuous bottle feeding; the pitch control of the bottle feeding screw 42 ensures uniform spacing between bottles and avoids congestion and misalignment; no manual intervention is required throughout the process, reducing human error.

[0052] Further, please refer to Figures 1 to 6 As a specific embodiment of the fully automatic light inspection machine for cartridge bottles provided by the present invention, the transition conveying mechanism 5 includes a receiving star wheel 51 and a transition screw 52.

[0053] The receiving star wheel 51 is rotatably connected to the machine body 1 in a vertical direction. The outer periphery of the receiving star wheel 51 is provided with a plurality of spaced receiving grooves 511. Each receiving groove 511 is used to receive the cartridge bottle after it has been rotated by the first spin member 3. The receiving star wheel 51 is driven by a fourth motor to drive the receiving star wheel 51 to rotate.

[0054] The transition screw 52 is rotatably connected to the machine body 1 in the horizontal direction. One end of the transition screw 52 is used to receive the cartridge bottle in the receiving groove 511 and to transport the cartridge bottle to the other end of the transition screw 52 in the axial direction.

[0055] A smooth transition is achieved through a combination of receiving star wheel 51 and transition screw 52: receiving star wheel 51 precisely connects to the pre-rotation station to avoid bottle jolting and fluctuations in the state of the liquid; transition screw 52 ensures uniform bottle spacing and matches the testing rhythm of the quality inspection components.

[0056] By adopting the above technical solutions, stable delivery can be achieved: avoiding bottle jolting and maintaining a uniform state of the liquid; the delivery speed of the transition screw 52 is adjustable, dynamically adapting to the rhythm of the pre-spinning and quality inspection processes; and the non-rigid contact delivery can reduce the risk of bottle wear.

[0057] Further, please refer to Figures 1 to 6 As a specific embodiment of the fully automatic light inspection machine for cartridge bottles provided by the present invention, the quality inspection component includes an accessory inspection mechanism 6, a rotary inspection mechanism, and a bottle bottom inspection mechanism a1.

[0058] The accessory inspection mechanism 6 is installed on the machine body 1. It can receive the cartridge bottles conveyed by the transition screw 52 and is used to inspect the top and side caps of the cartridge bottles.

[0059] The rotating inspection mechanism is installed on the machine body 1. It can receive the cartridge bottles after they have been inspected by the accessory inspection mechanism 6 and is used to perform rotating inspection on the appearance and contents of the cartridge bottles.

[0060] The bottle bottom detection mechanism a1 is installed on the machine body 1. It can receive the cartridge bottles after they have been detected by the rotary detection mechanism and is used to detect the bottom of the cartridge bottles.

[0061] Multiple channel star wheels a2 are rotatably connected to the machine body 1 in the vertical direction, and the multiple channel star wheels a2 are spaced apart; each channel star wheel a2 has multiple channel grooves a21 spaced apart on its outer periphery, and each channel groove a21 is used to connect with the tested cartridge bottle to transport the cartridge bottle to different positions.

[0062] Among them, after the cartridge bottles are inspected by the accessory inspection mechanism 6, the rotating inspection mechanism and the bottle bottom inspection mechanism a1, defective cartridge bottles are suitable to be transported to the non-conforming product collection container through the dividing star wheel a2, and non-defective cartridge bottles are suitable to be transported to the conforming product collection container through the dividing star wheel a2.

[0063] The cartridge bottle enters the accessory inspection mechanism 6 to check the sealing of the top cap and the integrity of the side cap; the bottle body that has completed the accessory inspection enters the rotating inspection mechanism to check for appearance cracks and impurities in the contents; the bottle body after rotating inspection enters the bottle bottom inspection mechanism a1 to check for bottle bottom damage and dents; the dividing star wheel a2 transports qualified and unqualified products to the corresponding collection containers according to the inspection results.

[0064] It adopts a multi-stage progressive inspection and intelligent classification mode: accessory, screw inspection, and bottle bottom inspection cover all key parts of the cartridge bottle; each stage independently completes specific inspection tasks to avoid error accumulation; the dividing star wheel A2 automatically diverts the flow according to the inspection signal to ensure that only qualified bottles enter the subsequent process.

[0065] By adopting the above technical solutions, all key parts and contents of the cartridge bottle are covered in multiple stages to ensure product quality; the intelligent sorting of multiple sorting star wheels a2 avoids errors in manual sorting; and defect traceability can help the continuous improvement of the production process.

[0066] Further, please refer to Figures 1 to 6 As a specific embodiment of the fully automatic light inspection machine for cartridge bottles provided by the present invention, the accessory inspection mechanism 6 includes a first inspection star wheel 61 and a first inspection unit 62.

[0067] The first detection star wheel 61 is rotatably connected to the machine body 1 in a vertical direction. The outer periphery of the first detection star wheel 61 is provided with a plurality of spaced first detection grooves 611. Each first detection groove 611 is used to receive the cartridge bottle conveyed by the transition screw 52. The first detection star wheel 61 is driven by a fifth motor to drive the first detection star wheel 61 to rotate.

[0068] The first detection unit 62 is located outside the first detection star wheel 61 and is used to detect the top and side caps of the cartridge bottles in each first detection groove 611.

[0069] The first detection star wheel 61 rotates, and the groove receives the cartridge bottle conveyed by the transition screw 52; the first detection star wheel 61 drives the bottle body to rotate, and the first detection unit 62 detects the sealing performance of the top cap and the integrity of the side cap from multiple angles; after the detection is completed, the first detection star wheel 61 conveys the bottle body to the rotating detection mechanism, and at the same time transmits the detection signal to the control system.

[0070] The first detection star wheel 61 rotates to achieve full-circumference inspection of accessories: the first detection star wheel 61 drives the bottle to rotate, so that the side cap is exposed in the field of view of the detection unit, avoiding blind spots in the inspection; the first detection unit 62 uses vision, pressure sensors and other methods to accurately identify defects such as loose top cap and deformed side cap.

[0071] By adopting the above technical solution, the rotation of the first detection star wheel 61 can eliminate the blind zone of the side cover detection; the special sensor is designed for the characteristics of the accessory, and the results are reliable.

[0072] Further, please refer to Figures 1 to 6 As a specific embodiment of the fully automatic light inspection machine for cartridge bottles provided by the present invention, the rotating inspection mechanism includes a quality inspection turntable 7, multiple second rotating components 8 and multiple light inspection units 9.

[0073] The quality inspection turntable 7 is vertically connected to the machine body 1 and is driven by a sixth motor to rotate the quality inspection turntable 7.

[0074] Multiple second spin components 8 are arranged at circumferential intervals on the quality inspection turntable 7. The second spin components 8 are used to receive the cartridge bottles after they have been inspected by the accessory inspection mechanism 6, so as to drive the cartridge bottles to rotate around their own axis.

[0075] Multiple light inspection units 9 surround the outer periphery of the quality inspection turntable 7, and are used to inspect the appearance and contents of the cartridges on each second spin member 8.

[0076] The sixth motor drives the quality inspection turntable 7 to rotate, which in turn drives the second spin component 8 to move in a cycle. The second spin component 8 receives the cartridge bottle after the accessory inspection. The second spin component 8 drives the bottle to rotate at high speed, and multiple light inspection units 9 inspect the appearance and contents from multiple angles. After the inspection is completed, the quality inspection turntable 7 transports the bottle to the bottle bottom inspection mechanism a1.

[0077] The system employs a combination of revolution, rotation, and multi-directional light inspection: the quality inspection turntable 7 revolutionizes to achieve batch inspection, the second rotating component 8 drives the bottle to rotate to eliminate blind spots in appearance inspection, and the multi-directional light inspection unit 9 provides sufficient illumination to ensure clear identification of bottle cracks and liquid impurities.

[0078] By adopting the above technical solutions, the self-rotating cartridge bottle can be combined with multi-directional light inspection to cover all external surfaces of the bottle and the internal liquid; spectral analysis can identify trace impurities and minor defects; and the rotary table cyclic operation is adapted to the needs of high-speed production lines.

[0079] Further, please refer to Figures 1 to 6 As a specific embodiment of the fully automatic light inspection machine for cartridge bottles provided by the present invention, the second spin member 8 includes a second rotating seat 81 and a second pressing seat 82.

[0080] The second rotating seat 81 is rotatably connected to the quality inspection turntable 7 in the vertical direction, and is driven by a seventh motor to drive the second rotating seat 81 to rotate; the second rotating seat 81 is used to connect with the lower end of the cartridge bottle.

[0081] The second pressing seat 82 is located on the upper side of the second rotating seat 81 and is coaxially arranged with the second rotating seat 81; the second pressing seat 82 is slidably connected to the quality inspection work turntable 7 in the vertical direction, and a second pressing member 83 is provided between the second pressing seat 82 and the quality inspection work turntable 7. The power output end of the second pressing member 83 is rotatably connected to the second pressing seat 82 to drive the second pressing seat 82 to move toward or away from the second rotating seat 81; the second pressing seat 82 is used to connect with the upper end of the cartridge bottle.

[0082] When the cartridge bottle is conveyed between the second rotating seat 81 and the second pressing seat 82, the second pressing member 83 is adapted to drive the second pressing seat 82 toward the second rotating seat 81 to clamp the cartridge bottle; when the second rotating seat 81 rotates, it is adapted to drive the cartridge bottle to rotate around its own axis.

[0083] The accessory inspection mechanism 6 transports the cartridge bottle between the second rotating seat 81 and the second pressing seat 82; the second pressing component 83 drives the pressing seat to slide down and coaxially clamps the bottle with the second rotating seat 81; the seventh motor drives the second rotating seat 81 to rotate, causing the bottle to rotate, and the light inspection unit 9 inspects the appearance and contents; after the inspection is completed, the second pressing component 83 drives the second pressing seat 82 to reset, and the quality inspection turntable 7 transports the bottle to the bottle bottom inspection mechanism a1.

[0084] The second pressing component 83 can be a cam structure, an eccentric wheel structure, or a telescopic cylinder, used to drive the second pressing seat 82 to move upward or downward.

[0085] The stability of the rotation is ensured by coaxial upper and lower clamping and active rotation: the second rotating seat 81 and the second pressing seat 82 are coaxially set to avoid eccentric shaking when the cartridge bottle rotates; the second pressing component 83 provides adjustable clamping force, which ensures sufficient friction to drive the rotation without damaging the bottle body; the seventh motor directly drives the second rotating seat 81, which has high power transmission efficiency and precise controllable speed.

[0086] By adopting the above technical solutions, high-precision coaxial clamping avoids bottle shaking and ensures detection accuracy; the clamping force and speed can be adjusted to adapt to different detection needs; and the dust-free clamping design avoids contamination of the medicine.

[0087] Further, please refer to Figures 1 to 6 As a specific embodiment of the fully automatic light inspection machine for cartridge bottles provided by the present invention, the bottle bottom inspection mechanism a1 includes a second inspection star wheel a11 and a second inspection unit a12.

[0088] The second detection star wheel a11 is rotatably connected to the machine body 1 in the vertical direction. The outer periphery of the second detection star wheel a11 is provided with a plurality of spaced second detection grooves a111. Each second detection groove a111 is used to receive the card bottle after being detected by the rotary detection mechanism. The second detection star wheel a11 is driven by an eighth motor to drive the second detection star wheel a11 to rotate.

[0089] The second detection unit a12 is located outside the second detection star wheel a11 and is used to detect the bottom of the cartridge bottle in each second detection groove a111.

[0090] The second detection star wheel a11 rotates, and the second detection groove a111 receives the cartridge bottle after the rotation inspection is completed; the second detection star wheel a11 drives the bottle body to rotate, and the second detection unit a12 detects the bottom damage, dents or thickness uniformity of the bottle; after the inspection is completed, the second detection star wheel a11 transports the bottle body to the channel star wheel a2, and at the same time transmits the detection signal to the control system.

[0091] The second detection star wheel a11 rotates to achieve full circumference detection of the bottle bottom: the second detection star wheel a11 drives the bottle to rotate, so that there is no blind spot in the detection of the bottle bottom edge; the second detection unit a12 can use visual (surface defects), ultrasonic (thickness defects) and other methods to specifically identify bottle bottom problems.

[0092] By adopting the above technical solutions, the star wheel rotation eliminates the blind spot in the detection of the bottle bottom edge; visual, ultrasonic and other detection methods can be selected according to the type of defect; and the detection of bottle bottom defects can prevent damage and leakage during use.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
