Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical packaging testing equipment, specifically to a fully automatic double-channel blister testing machine. Background Technology

[0002] Blister packaging is widely used in the pharmaceutical industry due to its excellent sealing, portability, and intuitive display of medicines. However, during the production process, blister packaging is prone to various defects, such as missing or broken tablets, discoloration, capsule cap separation, poor blister formation (e.g., poor blister pressing or blowing), holes in the aluminum foil seal, die-cutting deviations, burrs on the blister pack surface, and missing or incorrect batch numbers. These defects directly affect the safety of the medicine and the user experience; therefore, rigorous quality inspection of blister packaging before shipment is crucial.

[0003] Currently, machine vision technology is widely used in the industry for automated inspection. However, existing blister pack inspection equipment still has many shortcomings: 1. Incomplete detection: Many devices use single-channel inspection or single-light source solutions, which are difficult to cover all types of defects. For example, cameras that inspect from above cannot effectively detect tiny holes at the bottom of aluminum foil; a single lighting method cannot highlight certain specific defects (such as missing R-corners on the edge of a tablet), resulting in blind spots in the inspection and a high rate of missed detection.

[0004] 2. Poor operational stability: During high-speed conveying, blister packs are prone to displacement, jumping, or falling, leading to blurred imaging or inaccurate positioning, affecting detection accuracy. Some equipment uses mechanical clamping or pressing methods, which pose a risk of damaging the packaging or pharmaceuticals.

[0005] 3. Difficulty in cleaning and maintenance: The pharmaceutical industry has extremely high requirements for equipment cleanliness (GMP standards). Existing equipment has a complex structure, is inconvenient to disassemble and assemble, has many blind spots for cleaning, and the powder generated by the direct friction between the belt and the metal parts may contaminate the product. Cleaning is time-consuming and labor-intensive.

[0006] 4. Unreliable rejection process: When using air blowing to reject defective products, the blister packs are prone to flipping and falling in the air due to their thinness, which may lead to rejection failure or blockage of the channel, affecting the overall efficiency of the production line.

[0007] 5. Poor equipment adaptability: The fixed discharge structure is difficult to be compatible with subsequent production lines of different heights and interface specifications, which limits the application range of the equipment.

[0008] Therefore, developing a fully automated blister testing machine that can achieve blind-spot-free operation, high precision, high stability, easy cleaning, and strong adaptability has become an urgent technical problem to be solved in this field. Utility Model Content

[0020] Compared with the prior art, the fully automatic double-channel blister testing machine provided by this utility model has the following significant advantages: 1. Achieved comprehensive, multi-angle, and blind-spot-free precision detection: Dual-station collaboration: Utilizing two inspection stations—a suction belt (with overhead lighting) and a transparent belt (with backlighting)—optimizes for different defects. The suction station effectively detects various defects on the front of the blister pack (such as missing tablets, damaged tablets, blister formation, batch numbers, etc.), while the transparent belt station, using backlight transmission, can extremely accurately detect bottom defects such as holes in the aluminum foil and foreign objects, completely eliminating the blind spots of single-inspection methods.

[0021] Multi-light source combination: Integrating multiple light sources such as bowl light, coaxial light, ring light, and backlight at different workstations, different types of defect features can be highlighted through different lighting angles and imaging principles, which greatly improves the accuracy of image processing and defect recognition rate.

[0022] 2. Extremely stable operation, ensuring detection accuracy and reliability: Negative pressure adsorption conveying: The suction belt station uses negative pressure to firmly adsorb the blister packs onto the belt, effectively preventing displacement, jumping and falling during high-speed operation, ensuring that the image captured by the camera is consistently in the same position, and laying a solid foundation for high-precision detection.

[0023] Wear-resistant design: The wear-resistant strips on the suction chamber separate the belt from the metal suction plate, significantly reducing wear and dust generation. This protects the belt's lifespan and prevents product contamination, meeting GMP requirements.

[0024] Transparent belt non-contact backlight: The backlight source and the transparent belt remain in a non-contact state, avoiding scratches or wear on the backlight panel caused by friction, and ensuring long-term stable lighting quality.

[0025] 3. The rejection process is precise and reliable: A baffle was added above the entrance of the rejection channel, which effectively restricted the flight attitude and flipping space of the blister packs that were rejected by air blowing, ensuring that the non-conforming products could enter the rejection channel smoothly in a stable posture, greatly reducing the risk of accidental rejection or blockage.

[0026] 4. Modular and user-friendly design for easy cleaning and maintenance: Each functional device (such as the suction chamber and belt tensioning mechanism) adopts a modular design, which is easy to disassemble and assemble, has no hidden dead corners, and facilitates quick cleaning and maintenance by operators, thus reducing operation and maintenance costs.

[0027] 5. High flexibility and adaptability: The finished product discharge channel device can be adjusted by rotating up and down and moving back and forth, so that its discharge height and interface width can be flexibly matched with different models of downstream collection equipment or packaging machines, thereby enhancing the versatility and integration capability of the whole machine in the production line.

[0028] 6. High degree of automation and intelligence: The entire process, from detection, judgment, rejection to counting and discharging, is fully automated without human intervention. It integrates counting fiber optics, which facilitates production management and data statistics, effectively improving production efficiency. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0048] A fully automatic double-channel blister pack inspection machine includes: a frame 1, a control console 2, an inspection device 3, a rejection device 4, and a finished product discharge channel device 5.

[0049] In one embodiment, the detection device includes a suction belt 301 detection station 30 and a transparent belt 310 detection station 31; the suction belt 301 detection station 30 is used for the first defect detection of the blister packs, and the transparent belt 310 detection station 31 is used for the second defect detection of the blister packs; the rejecting device 4 is used to reject unqualified blister packs, and the finished product discharge channel device 5 is used to output qualified blister packs; The control console 2 is electrically connected to and controls the detection device 3, the rejection device 4, and the finished product discharge channel device 5.

[0050] Specifically, such as Figures 1 to 2As shown, when the blister packs are conveyed forward, the suction belt 301 uses negative pressure from the fan to suction the blister packs onto the belt through the suction chamber 302. A small hole in the middle of the suction chamber 302 prevents the blister packs from falling off during forward conveying. Upon passing the trigger fiber 32, a signal is transmitted to the industrial control computer. When the blister packs reach the first camera 34, the ring light 35 and coaxial light 36 begin to operate, starting blister pack inspection. This mainly detects defects in the blister pack (displacement during punching, bright stripes, burrs on the surface), foreign objects on the surface, unclear mesh patterns, blister pack defects (poor blowing, compressed bubbles, etc.), missing tablets, tablet defects, discoloration, broken particles inside the blister pack, foreign objects in the capsule, discoloration of the capsule cap, absence of batch numbers, foreign objects in the batch number, and missing batch number characters. When the blister packs reach the second camera 34, the ring light 37 begins to operate, starting blister pack inspection. This mainly uses different light sources... To demonstrate different imaging effects, it detects the presence or absence of batch numbers, missing batch number characters, damaged or broken tablet edges, and blister pack compression. After inspection, it is conveyed forward. Since there is no negative pressure at the connection between the upper and lower ends, the blister pack automatically falls to the inspection station 31 of the transparent belt 310. It is then conveyed forward by the transparent belt 310. After being triggered by photoelectric sensors, the signal is transmitted to the industrial control computer. When the blister pack reaches the third camera 38, the backlight and plane light start working to start inspecting the blister pack. This mainly detects holes in the aluminum foil, missing trademark information, and foreign objects on the aluminum foil surface. After all the blister packs have been inspected, they are conveyed forward again. If there are defects in the blister packs, the industrial control computer will issue an instruction to the solenoid valve. The defective blister packs are removed through the waste gas nozzle 42 and collected in the waste removal channel 40. Qualified blister packs will fall onto the finished product discharge belt, where a counting fiber optic cable 53 passes by for easy counting and collection.

[0051] In one embodiment, the suction belt 301 inspection station 30 is provided with two sets and includes: suction belt 301, suction cavity 302, suction pipe 303 and driven tension wheel 523 device 6; the two sets of suction belt 301 inspection stations 30 are synchronously connected through drive wheel device 7; The driven tension wheel 523 device 6 and the driving wheel device 7 are mounted on the back plate of the frame 1, and the two ends of the suction belt 301 are respectively sleeved with the driven tension wheel 523 device 6 and the driving wheel device 7 so that the driving wheel device 7 drives the driven tension wheel 523 device 6 to rotate through the suction belt 301. The suction cavity 302 is located inside the suction belt 301 and between the driven tension wheel 523 device 6 and the driving wheel device 7.

[0052] In one embodiment, the suction cavity 302 is composed of a cover 314, a suction perforated plate 315, and a wear-resistant strip 316; The suction plate 315 has a plurality of suction holes and is fixedly installed on the cover 314. The wear-resistant strip 316 is installed on the suction plate 315 and the suction plate 315 cooperates with the suction belt 301.

[0053] In one embodiment, the upper part of the detection station 30 of the suction belt 301 is provided with a trigger fiber 32, and the bottom is provided with a first camera 34 and a second camera 34. The first camera 34 is equipped with a bowl light 35 or a coaxial light 36, and the second camera 34 is equipped with a ring light 37. The upper part of the detection station 31 of the transparent belt 310 is provided with a trigger fiber 32 and a third camera 38.

[0054] In one embodiment, the drive wheel device 7 is provided with two sets, one end of which is connected to the two sets of suction belt 301 detection stations 30 or the two sets of transparent belt 310 detection stations 31 respectively, and the other end is connected through the synchronous wheel 76. The drive wheel device 7 includes: a drive shaft 70, a second drum-shaped wheel 71, a bearing seat 72, a nut 73, a coupling 74, and a clamping plate 75; One end of the drive shaft 70 is connected to one end of the synchronous pulley 76 via a coupling 74. The drive shaft 70 is rotatably connected to the bearing housing 72 via a bearing 520. The nut 73 is screwed onto one end of the drive shaft 70 to fix the drive shaft 70 to the bearing housing 72. The second drum-shaped wheel 71 is fixedly sleeved on the outside of the drive shaft 70. The clamping plate 75 is fixedly installed on the second drum-shaped wheel 71 and one end of the drive shaft 70 and is fixed by screws.

[0055] Specifically, such as Figures 3 to 9 As shown, each component is installed on the back plate, and then the suction belt 301 is installed. The screw at the tensioning point of the driven pulley is used to tension the belt through the tensioning plate 65. After adjustment to a runnable state, the synchronous pulley 76 on the drive pulley device 7 is driven by the motor and synchronous belt, so that the drive pulley device 7 starts to run. At the same time, the fan creates a negative pressure state inside the suction chamber 302 through the pipe on the suction chamber 302. There are suction holes on both sides of the suction plate 315 on the suction chamber 302 device. The suction holes here can adsorb the belt onto the wear-resistant strip 316 on the suction plate 315. The wear-resistant strip 316 also has corresponding holes, which can reduce belt jumping during operation. The function of the wear-resistant strip 316 is to better protect the belt from contact with metal, generating powder and contaminating the product. The suction hole in the middle of the suction plate 315 is mainly used to adsorb the blister packs, so that the blister packs are adsorbed on the belt and move forward to perform defect detection at two workstations.

[0056] In one embodiment, the transparent belt 310 detection station 31 is provided with two sets, including: transparent belt 310, front end support plate 311, backlight 312, rear end support plate 313 and driven tension wheel 523 device 6, and the two sets of transparent belt 310 detection station 31 drive wheel device 7 are synchronously connected through drive wheel device 7. The driven tension wheel 523 device 6 and the driving wheel device 7 are mounted on the back plate of the frame 1, and the two ends of the transparent belt 310 are respectively sleeved with the driven tension wheel 523 device 6 and the driving wheel device 7 so that the driving wheel device 7 drives the driven tension wheel 523 device 6 to rotate through the suction belt 301. The front support plate 311, the backlight 312 and the rear support plate 313 are located inside the transparent belt 310 and between the driven tension wheel 523 device 6 and the driving wheel device 7. The backlight 312 is mounted by a bracket between the front support plate 311 and the rear support plate 313.

[0057] Specifically, such as Figures 3 to 10 As shown, each component is installed on the back plate, and then the transparent belt 310 is installed. The screw at the tensioning point of the driven wheel is used to tension the belt through the tensioning plate 65. After adjusting to a runnable state, the synchronous pulley 76 on the drive wheel device 7 is driven by the motor and the synchronous belt, so that the drive wheel device 7 starts to run. At this time, the bubble has fallen from the front suction belt 301 detection station 30 onto the transparent belt 310. Below the belt are the front support plate 311, the backlight 312 bracket and the rear support plate 313. The backlight 312 is installed on the backlight 312 bracket. The belt does not touch the light source to avoid scratching the outer surface of the light source during operation, which would affect the detection.

[0058] In one embodiment, the waste removal device 4 includes: a waste removal channel 40, a first baffle 41, and a waste removal nozzle 42; The first baffle 41 and the waste removal nozzle 42 are fixedly installed on the back plate of the frame 1. The waste removal channel 40 is fixedly installed on the lower side of the back plate of the frame 1 and is located between the outlet of the transparent belt 310 detection station 31 and the inlet of the finished product discharge channel device 5.

[0059] Specifically, such as Figure 11As shown, after all blister packs have been inspected, the computer identifies whether they are qualified products. If a blister pack is defective, the computer sends a signal to the solenoid valve, which, through the waste gas nozzle 42, removes the defective blister pack into the waste removal channel 40 for collection. There is a baffle above this channel. This baffle is used because when the waste gas nozzle 42 is working, there is a chance that the blister pack will flip over when it is being removed, causing instability. The baffle at the top can stabilize the blister pack's posture and not affect subsequent actions. Subsequently, qualified blister packs fall onto the conveyor belt at the finished product outlet and are conveyed forward for collection.

[0060] In one embodiment, the finished product discharge channel device 5 is provided in two sets and includes: an inner side plate 50, an outer side plate 51, a driven wheel device 52, a counting fiber optic cable 53, a second baffle 51, a shifting plate 55, a fixed adjusting plate 56, and a flat belt 57; the two sets of finished product discharge channel devices 5 are synchronously connected through the drive wheel device 7. The inner side plate 50 and the outer side plate 51 are arranged symmetrically, and the driving wheel device 7 is installed at one end of the inner side plate 50 and the outer side plate 51, and the driven wheel device 52 is installed at the other end of the inner side plate 50 and the outer side plate 51. The two ends of the flat belt 57 are respectively sleeved with the driven wheel device 52 and the driving wheel device 7 so that the driving wheel device 7 drives the driven wheel device 52 to rotate through the flat belt 57. The second baffle 51 is located on both sides of the flat belt 57. The counting optical fiber 53 is fixedly installed at one end of the second baffle 51. The shift plate 55 is installed inside the back plate of the frame 1. The fixed adjustment plate 56 is installed on the driving wheel device 7 and connected to the shift plate 55.

[0061] In one embodiment, the driven wheel device 52 includes: a bearing 520, a driven shaft 521, a first driven wheel 522, and a tension wheel 523; The first driven wheel 522 is rotatably mounted on the driven shaft 521 via a bearing 520. The driven shaft 521 has tension threaded holes at both ends. The tension wheel 523 is mounted on both ends of the driven shaft 521 via screws that mate with the tension threaded holes.

[0062] Specifically, such as Figures 12 to 16As shown, each component is installed on the back plate, and then the flat belt 57 is installed. The screws at the tensioning point of the driven wheel are used to tension the belt through the inner and outer side plates 51. After adjustment to a working state, the synchronous pulley 76 on the drive wheel device 7 is driven by the motor and synchronous belt, so that the drive wheel device 7 starts to run. When the blister pack is thrown from the transparent belt 310 detection station 31 onto the flat belt 57 of the finished product discharge device, it is conveyed forward, passes through the counting fiber optic cable 53, and finally enters the finished product box for collection. The finished product discharge device here can be rotated up and down to better accommodate the height of more connecting lines. At the same time, the entire finished product discharge device can be moved back and forth to adjust the width of the rejection gate, so as to better accommodate more unqualified blister packs.

[0063] In one embodiment, the driven tensioning wheel device consists of a second driven wheel 60, a first fixed plate 61, a second fixed plate 62, a spacer 63, a bearing 520, a first drum-shaped wheel 64, a tensioning plate 65, and a tensioning screw 66. The first fixing plate 61 and the second fixing plate 62 are fixedly installed at both ends of the second driven wheel 60. The first drum-shaped wheel 64 is rotatably installed on the second driven wheel 60 through the bearing 520. The spacer 63 is sleeved on both ends of the second driven wheel and is located between the first fixing plate 61 and the first drum-shaped wheel 64. One end of the tensioning plate 65 is fixedly installed on the outside of the first fixing plate 61 and the second fixing plate 62, and the other end is connected to the cover 314 or the front support plate 311 through the tensioning screw 66.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
