Description

Technical Field

[0001] The present application relates to the field of testing equipment, and in particular to an automatic light inspection machine for BFS products. Background Art

[0002] The Blow Fill Seal (BFS) machine can realize the steps of blowing, filling and sealing the ampoule bottles under aseptic conditions. It is widely used in the packaging production of various liquid medicines and cosmetics.

[0003] In the related technology, after the row of ampoules is produced by the BFS machine, it needs to undergo a series of tests to ensure the integrity of the row of ampoules and the cleanliness of the liquid inside. At present, the inspection of row of ampoules is mainly carried out by manual sampling. During the specific inspection, the row of ampoules to be inspected are stood up and placed under the light board for visual inspection.

[0004] Regarding the above-mentioned related technologies, on the one hand, manual sampling is usually prone to missed inspections or wrong inspections, and the detection efficiency is low; on the other hand, since some impurity particles are easily precipitated at the bottom of the row of ampoules, when the row of ampoules is stood up and placed on the light board for inspection, it is generally impossible to observe the specific situation of the liquid in this area. It is usually necessary to manually adjust the position of the ampoule or shake the ampoule repeatedly before the liquid situation inside the ampoule can be confirmed. The overall operation is relatively cumbersome, and therefore, there is room for improvement. Summary of the invention

[0005] In order to improve the inspection efficiency of row ampoules and facilitate complete and thorough inspection of row ampoules, the present application provides a BFS product automatic light inspection machine.

[0006] The present application provides a BFS product automatic light inspection machine, which adopts the following technical solution: An automatic light inspection machine for BFS products, comprising a control module, a feeding conveying mechanism, an inverted conveying mechanism, an inclined conveying mechanism, an upright conveying mechanism and a discharging conveying mechanism; The feeding and conveying mechanism is used to convey the inverted row of ampoule bottles; The inverted conveying mechanism is connected to the feeding conveying mechanism and is used to convey the inverted row of ampoule bottles; The inclined conveying mechanism is docked with the inverted conveying mechanism to convey the row of ampoules and flip the row of ampoules from inverted to inclined; The upright conveying mechanism is docked with the inclined conveying mechanism to convey the row of ampoules and flip the row of ampoules from inclined to upright; The discharging conveying mechanism is connected to the upright conveying mechanism, and is used to convey the row of ampoule bottles and flip the installed bottles from upright to horizontal; The inverted conveying mechanism, the inclined conveying mechanism and the upright conveying mechanism are all provided with an image acquisition component, and the image acquisition component is arranged close to the conveying path of the row of ampoule bottles; the discharging conveying mechanism is also provided with a material removal component, and the image acquisition component and the material removal component are both electrically connected to the control module, and the image acquisition component is used to acquire the image of the row of ampoule bottles and feed it back to the control module, and the control module determines whether the row of ampoule bottles is qualified according to the feedback image, and controls the material removal component to remove unqualified row of ampoule bottles from the discharging conveying mechanism.

[0007] By adopting the above technical solution, the row of ampoule bottles to be inspected and in an inverted state are introduced into the BFS product automatic light inspection machine through the feeding conveying mechanism, and are successively conveyed through the inverted conveying mechanism, the inclined conveying mechanism, the flipping conveying mechanism and the upright conveying mechanism, and finally discharged through the discharging conveying mechanism. Under the action of the inverted conveying mechanism, the inclined conveying mechanism, the flipping conveying mechanism and the upright conveying mechanism, the row of ampoule bottles gradually transition from an inverted state to an inclined state and an upright state. During this period, the images of the row of ampoule bottles in "inverted", "inclined" and "upright" are successively acquired by the image acquisition components at various locations of the inverted conveying mechanism, the inclined conveying mechanism and the upright conveying mechanism, and the images are fed back to the control module. Then, the control module controls the rejecting component at the discharging conveyor belt according to the feedback image situation to automatically reject the unqualified row of ampoule bottles, thereby completing the inspection of the row of ampoule bottles and the automatic rejection of unqualified products. Compared with the traditional manual inspection method, it is easier to obtain the specific conditions inside and outside the row of ampoules in a more comprehensive and thorough manner; at the same time, the inspection process does not require manual intervention, which is conducive to improving the overall inspection efficiency of the row of ampoules.

[0008] Preferably, the image acquisition component includes a light source board and a camera, and the camera and the light source board are respectively supported on opposite sides of the conveying path of the row of ampoule bottles. The camera is connected to the control module to capture the image of the row of ampoule bottles and feed it back to the control module.

[0009] By adopting the above technical solution, when the row of ampoule bottles is conveyed to a position opposite to the camera, the camera is used to capture an image of the row of ampoule bottles and the image is fed back to the control module to complete the acquisition of the image of the row of ampoule bottles; by respectively supporting the camera and the light source board on opposite sides of the row of ampoule bottle conveying path, the light source board is used to provide sufficient light source for the camera, which is conducive to enabling the camera to capture the internal and external details of the row of ampoule bottles more clearly.

[0010] Preferably, the inverted conveying mechanism includes two inverted conveyor belts; the input ends of the two inverted conveyor belts extend to the output end of the feeding conveying mechanism, and a conveying gap for clamping and conveying the tails of the row of ampoule bottles is formed between the two inverted conveyor belts.

[0011] By adopting the above technical solution, the conveying gap formed by the two inverted conveyor belts is used to clamp and convey the bottle tails of the row of ampoule bottles transmitted by the feed conveyor belt, so that the bottle bodies of the row of ampoule bottles are better exposed, which is conducive to the image acquisition device at the inverted conveying mechanism to more completely acquire the image of the row of ampoule bottles when they are in an inverted state.

[0012] Preferably, the inclined conveying mechanism comprises a transition conveying portion and an inclined conveying portion; The transition conveying part is connected to the output end of the inverted conveying mechanism, and is used to convey the row of ampoules and flip the row of ampoules from an inverted state to an inclined state; The inclined conveying part is butted with the transition conveying part; the inclined conveying part comprises two inclined conveying belts, and a conveying gap for clamping and conveying the tails of the inclined row of ampoule bottles is formed between the two inclined conveying belts.

[0013] By adopting the above technical scheme, after the transition conveying part is used to smoothly transition the row of ampoule bottles from an inverted state to an inclined state, the tail of the row of ampoule bottles in the inclined state is clamped through the conveying gap between the two inclined conveyor belts and the row of ampoule bottles is continued to be conveyed. On the one hand, the bottle body of the row of ampoule bottles can remain exposed, which is convenient for the image acquisition component to better capture the details of the row of ampoule bottles in the inclined state. On the other hand, when there are floating foreign matter and precipitated foreign matter in the row of ampoule bottles, by tilting the row of ampoule bottles, it is convenient to make the precipitated foreign matter and floating foreign matter at the bottom of the liquid in the row of ampoule bottles flow better, which is beneficial for the control module to better judge the specific situation of the liquid in the row of ampoule bottles through the image feedback from the image acquisition device at the inclined conveying mechanism, which is beneficial to improve the accuracy of the control module's judgment on the row of ampoule bottles.

[0014] Preferably, the upright conveying mechanism comprises an overturning conveying component and an upright conveying component; The overturning conveying assembly is docked with the inclined conveying part, and is used to convey the row of ampoules and overturn the row of ampoules from an inclined position to an upright position; The upright conveying assembly includes a first upright conveying portion and a second upright conveying portion; The first upright conveying part is connected to the flip conveying assembly, and the first upright conveying part includes two first upright conveying belts, and the two first upright conveying belts form a conveying gap for clamping and conveying the bottle heads of the upright row of ampoule bottles; The second upright conveying part is connected to the first upright conveying part, and the second upright conveying part includes two second upright conveying belts, and the two second upright conveying belts form a conveying gap for clamping and conveying the tails of the upright row of ampoule bottles.

[0015] By adopting the above technical solution, the first flip conveyor and the second flip conveyor cooperate to smoothly transition the row of ampoules from an inclined state to an upright state, which is conducive to further improving the fluidity of floating foreign matter and precipitated foreign matter in the row of ampoules, and facilitating the image acquisition component at the subsequent upright conveying mechanism to better capture the internal and external details of the row of ampoules. The row of ampoules is transported by the first upright conveyor and the second upright conveyor, so that the head and the tail of the row of ampoules can leak out alternately, which is conducive to the image acquisition device at the upright conveying mechanism to more completely acquire the image of the row of ampoules.

[0016] Preferably, the discharging conveying mechanism comprises a discharging conveying belt; the material-removing assembly comprises a material-removing limiting rod and a material-removing air knife, the material-removing limiting rod is supported above the input end of the discharging conveying belt and the input end of the material-removing limiting rod extends to the output end of the second upright conveying part, for the upright row of ampoule bottle heads to be placed; the material-removing air knife is located at one side of the discharging conveying belt, and the material-removing air knife faces the gap between the material-removing limiting rod and the conveying surface of the discharging conveying belt; the material-removing air knife is connected to a control module; When the unqualified row of ampoule bottles is transported by the unqualified unqualified unqualified unqualified row of ampoule bottles to the ejection air knife, the control module controls the ejection air knife to blow the unqualified row of ampoule bottles away from the unqualified unqualified unqualified unqualified unqualified row of ampoule bottles ...loading conveyor belt.

[0017] By adopting the above technical scheme, after the upright conveying mechanism transfers the upright row of ampoule bottles to the discharge conveyor belt, the row of ampoule bottles overlap on the rejecting limit rod to maintain an upright state during the transmission of the row of ampoule bottles on the discharge conveyor belt; when the unqualified row of ampoule bottles moves to be opposite to the rejecting air knife, the control module controls the rejecting air knife to blow compressed air toward the unqualified row of ampoule bottles to make the unqualified row of ampoule bottles topple and slide out of the discharge conveyor belt, thereby realizing the automatic rejection of the unqualified row of ampoule bottles.

[0018] Preferably, the output end of the discharge conveyor belt is connected to the rear-end packaging equipment used in conjunction with the BFS product automatic light inspection machine, and a transition plate is also supported at the output end of the discharge conveyor belt, and the transition plate extends to the conveying plane of the discharge conveyor belt and is arranged flush with the conveying plane of the discharge conveyor belt.

[0019] By adopting the above technical solution, the setting of the transition plate is conducive to better connection between the output end of the discharge conveyor belt and the rear-end packaging equipment.

[0020] Preferably, an auxiliary conveyor belt is supported above the transition plate, and a conveying gap for clamping and conveying horizontally arranged ampoule bottles is formed between the auxiliary conveyor belt and the transition plate.

[0021] By adopting the above technical solution, since the transition plate area is a non-powered area, during the subsequent conveying process, the row of ampoules is easily accumulated on the transition plate and causes jamming. By supporting an auxiliary conveyor belt above the transition plate, the row of ampoules conveyed to the transition plate by the discharge conveyor belt can be better conveyed out of the transition plate through the auxiliary conveyor belt.

[0022] Preferably, both the input end of the inverted conveying mechanism and the input end of the upright conveying mechanism are provided with a defoaming part, and the defoaming part includes a defoaming cylinder, and the defoaming cylinder is arranged toward the conveying path of the row of ampoule bottles, and the piston rod of the defoaming cylinder is connected to a defoaming rod.

[0023] By adopting the above technical scheme, bubbles are easily generated in the internal liquid of the row of ampoule bottles due to transportation and overturning, which may easily interfere with the judgment of the subsequent control module on the image. Through the setting of the defoaming part, when the row of ampoule bottles are transported to the opposite side of the defoaming cylinder, the defoaming cylinder is used to drive the defoaming rod to knock the row of ampoule bottles to eliminate the bubbles in the liquid inside the row of ampoule bottles and reduce the interference of bubbles on the subsequent control module.

[0024] Preferably, the input end of the inverted conveying mechanism is also provided with an electrostatic elimination unit, and the electrostatic elimination unit includes two negative ion fans, which are respectively supported at the bottom of the two inverted conveyor belts and are arranged toward the conveying path of the row of ampoules.

[0025] By adopting the above technical scheme, the bottle bodies of the row ampoule bottles are easily adsorbed with dust due to static electricity, which causes interference in the control module's judgment of the internal and external conditions of the row ampoule bottles. By setting up the static electricity elimination unit, two negative ion fans are used to blow negative ion wind to the row ampoule bottles during the transmission process, and the negative ions generated by the negative ion fans are combined with the positive ions in the air, thereby effectively neutralizing and removing the static electricity on the surface of the row ampoule bottles, reducing the interference of statically adhered dust on the subsequent control modules.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. During the process of conveying the row of ampoules to be inspected through the inverted conveying mechanism, the inclined conveying mechanism, the flipped conveying mechanism and the upright conveying mechanism, the posture of the row of ampoules to be inspected changes from inverted to inclined and finally to upright. During this period, the image acquisition components at the inverted conveying mechanism, the inclined conveying mechanism, the flipped conveying mechanism and the upright conveying mechanism acquire images of the row of ampoules in inverted, inclined and upright positions and feed them back to the control module. The control module determines whether the row of ampoules is qualified according to the feedback image, and controls the rejecting component on the discharging conveying mechanism to reject the unqualified row of ampoules from the discharging conveying mechanism; the detection of the row of ampoules and the automatic rejection of defective products are realized, which is conducive to improving the overall detection efficiency of the row of ampoules.

[0027] 2. Through the arrangement of the first vertical conveying part and the second vertical conveying part, the two first vertical conveying belts of the first vertical conveying part and the two second vertical conveying belts of the second vertical conveying part are used to clamp and convey the bottle heads and bottle tails of the vertical row of ampoule bottles respectively, so that the image acquisition device at the vertical conveying mechanism can more completely acquire the image of the row of ampoule bottles.

[0028] 3. Through the setting of the defoaming part, when the row of ampoules is conveyed to the defoaming place, the defoaming cylinder can drive the defoaming rod to hit the row of ampoules to eliminate the bubbles in the row of ampoules and reduce the interference of bubbles on the subsequent control module in judging the image.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-10 This application is described in further detail.

[0041] like Figure 1 The inner cavity of the bottle head of the row ampoule bottle is connected with the inner cavity of the bottle body, and the cavity opening at the top of the bottle head is larger than the cavity opening at the top of the bottle body.

[0042] The present application embodiment discloses a BFS product automatic light inspection machine, referring to Figure 2 and Figure 3 , including a control module, a feeding conveying mechanism 1, an inverted conveying mechanism 2, an inclined conveying mechanism 3, an upright conveying mechanism 4 and a discharging conveying mechanism 5. The feeding conveying mechanism 1 and the inverted conveying mechanism 2 are both used to convey inverted row ampoule bottles. The inclined conveying mechanism 3 is used to convey row ampoule bottles and flip the row ampoule bottles from inverted to inclined; the upright conveying mechanism 4 is used to convey row ampoule bottles and flip the row ampoule bottles from inclined to upright; the discharging conveying mechanism 5 is used to convey row ampoule bottles and flip the row ampoule bottles from upright to lying. The inverted conveying mechanism 2, the inclined conveying mechanism 3 and the upright conveying mechanism 4 are all provided with an image acquisition component 6, which is arranged close to the conveying path of the row ampoule bottles; the image acquisition component 6 is electrically connected to the control module, and is used to acquire images of the row ampoule bottles and feed them back to the control module.

[0043] The image acquisition component 6 includes a camera 61 and a light source board, which are respectively located on opposite sides of the conveying path of the row of ampoules and both face the conveying path facilities of the row of ampoules. The camera 61 is electrically connected to the control module, and is used to capture the image of the row of ampoules and feed it back to the control module so that the control module can determine whether the row of ampoules is qualified. The light source board provides a light source for the camera 61, so that the camera 61 can better capture the image of the row of ampoules. In this embodiment, the shooting of the camera 61 is completed by the control module in conjunction with the sensor.

[0044] Reference Figure 2 and Figure 3 The feeding conveying mechanism 1 comprises a feeding conveying belt 11, a manifold block 12 is supported on the input end of the feeding conveying belt 11, a main channel 121 and two auxiliary channels 122 are formed on the manifold block 12 for the inverted row of ampoules to pass through, the input ends of the two auxiliary channels 122 are connected to the blow-fill-seal integrated machine used with the BFS product automatic light inspection machine, and the output ends of the two auxiliary channels 122 are evenly connected to the main channel 121; the two auxiliary channels 122 are close to the main channel 121. A section near the main flow channel 121 is provided with a material blocking cylinder 123, and the piston rods of the material blocking cylinders 123 are connected to material blocking blocks. When a row of ampoules are introduced into the main flow channel 121 at one side flow channel 122, the material blocking cylinder 123 at another side flow channel 122 drives the material blocking block to block the output end of the side flow channel 122, so as to avoid the situation that the row of ampoules at two side flow channels 122 flow into the main flow channel 121 at the same time, causing the main flow channel 121 to be blocked. In this embodiment, the material blocking cylinder 123 is electrically connected to the control module. The switching of the state of the material blocking cylinder 123 is completed by the control module in conjunction with the sensor.

[0045] An interception assembly 13 is also provided on the feed conveyor belt 11, and the interception assembly 13 includes an interception air knife 132, an interception limit rod 131 and an interception collection box 133; the interception limit rod 131 is supported above the feed conveyor belt 11, and the input end of the interception limit rod 131 extends to the output end of the main channel 121, and the interception limit rod 131 is used for overlapping the tail ends of the inverted row of ampoule bottles to keep the row of ampoule bottles in an inverted state; the interception air knife 132 and the interception collection box 133 are respectively supported on opposite sides of the feed conveyor belt 11, and the interception air knife 132 is set towards the gap between the interception limit rod 131 and the feed conveyor belt 11.

[0046] When the inverted conveying mechanism 2, the inclined conveying mechanism 3, the upright conveying mechanism 4 and the discharging conveying mechanism 5 fail to convey the row of ampoules, the control module controls the interception air knife 132 to blow the inverted row of ampoules from the main channel 121 out of the feeding conveyor belt 11 to limit the continued input of the row of ampoules. In this embodiment, the interception air knife 132 is electrically connected to the control module; the opening and closing of the interception air knife 132 is completed by the control module in conjunction with the sensor.

[0047] The feed conveyor belt 11 is also supported with a first guide member 111, the input end of the feed guide member extends to the interception limit rod 131, and the output end of the feed guide member extends to the output end of the feed conveyor belt 11. The first guide member 111 includes two first guide plates, and the two first guide plates form a conveying gap for the inverted row of ampoule bottles to pass through. The first guide member 111 is used to assist in limiting the inverted row of ampoule bottles on the feed conveyor belt 11, so that the row of ampoule bottles can better maintain an inverted state.

[0048] Reference Figure 2 and Figure 4 The inverted conveying mechanism 2 includes two inverted conveying belts 21, which cooperate to form a conveying gap for clamping and conveying the tail of the inverted row of ampoule bottles; the input end and the output end of the inverted conveying belt 21 are both arranged vertically, and the input ends of the two inverted conveying belts 21 extend above the output end of the feed conveyor belt 11, so that the tail of the inverted row of ampoule bottles subsequently transmitted through the feed conveyor belt 11 can smoothly enter the conveying gap of the two inverted conveyor belts 21. The tail of the row of ampoule bottles is clamped and conveyed by the two inverted conveyor belts 21, so that the body of the row of ampoule bottles can be better exposed, which is conducive to the camera 61 at the inverted conveying mechanism 2 to better obtain the internal and external conditions of the row of ampoule bottles.

[0049] The input ends of the two inverted conveyor belts 21 are provided with static elimination parts, which include two negative ion fans 22, which are respectively supported at the bottom of the input ends of the two inverted conveyor belts 21, and are both arranged toward the conveying path of the row of ampoules; the negative ion fans 22 are electrically connected to the control module, and when the row of ampoules is delivered to the negative ion fans 22, the negative ion airflow is blown toward the row of ampoules through the control module to eliminate static electricity on the periphery of the row of ampoules and dust adhered to the periphery of the row of ampoules due to static electricity, so as to reduce the interference of dust adhered to the periphery of the row of ampoules due to static electricity on the subsequent control module's judgment on whether the ampoules are qualified. In this embodiment, the opening and closing of the negative ion fans 22 is realized by the control module in conjunction with the sensor.

[0050] There are two image acquisition components 6 located at the inverted conveying mechanism 2, and the cameras 61 of the two image acquisition components 6 are respectively located on the opposite sides of the two inverted conveyor belts 21, so as to more completely acquire the image of the row of ampoule bottles.

[0051] Specifically, the camera 61 located at the inverted conveying mechanism 2 is used to capture the image of the row of ampoule bottles in an inverted state and feed it back to the control module so that the control module can determine whether there are defects in the ampoule bottle body and bottle head, whether there are floating impurity particles in the row of ampoule bottle body, and whether the liquid level in the row of ampoule bottle body is qualified.

[0052] The feeding conveying mechanism 1 cooperates with the inverted conveying mechanism 2 to first convey the row of ampoules in an inverted manner, which is beneficial to reducing the situation where part of the liquid remains in the bottle head of the row of ampoules when the row of ampoules are first conveyed upright, causing an error in the liquid level in the bottle body of the row of ampoules.

[0053] Reference Figure 2 and Figure 5 The inclined conveying mechanism 3 includes a transition conveying part 31 and an inclined conveying part 32; the transition conveying part 31 is used to convey the row of ampoules and flip the row of ampoules from inverted to inclined.

[0054] The transition conveying part 31 includes two twisting conveying belts 311; the two twisting conveying belts 311 form a conveying gap for clamping and conveying the ampoule bottles in a row. The input ends of the two twisting conveying belts 311 extend above the output ends of the two inverted conveying belts 21, respectively, and the input ends of the two twisting conveying belts 311 are axially arranged vertically to achieve the docking of the transition conveying part 31 and the inverted conveying mechanism 2; the output ends of the two twisting conveying belts 311 are axially inclined.

[0055] The inclined conveying part 32 includes two inclined conveying belts 321, and the two inclined conveying belts 321 form a conveying gap for clamping and conveying the tails of the inclined row of ampoule bottles.

The input ends of the two inclined conveying belts 321 extend above the output ends of the two twisting conveying belts 311, respectively, to achieve the docking of the inclined conveying part 32 and the transition conveying part 31.

[0056] There are two image acquisition components 6 located at the inclined conveying mechanism 3. The cameras 61 of the two image acquisition components 6 are respectively located at two sides of the inclined conveying belts 321 away from each other and are both arranged toward the conveying path of the row of ampoule bottles.

[0057] Specifically, the camera 61 located on the inclined conveying mechanism 3 is used to capture the image of the row of ampoule bottles in an inclined state and feed it back to the control module so that the control module can determine whether there are defects in the ampoule bottle body and bottle head, and whether there are floating impurity particles and precipitated impurities in the row of ampoule bottle body.

[0058] The transition conveying part 31 cooperates with the inclined conveying part 32 to transition the row of ampoule bottles in an inverted state to an inclined state, and then the inclined conveying part 32 clamps the tail of the inclined row of ampoule bottles and conveys them. When there are precipitated impurity particles in the row of ampoule bottles, it is helpful to improve the fluidity of the precipitated impurity particles and floating impurity particles in the row of ampoule bottles, which is beneficial for the camera 61 at the inclined conveying mechanism 3 to better capture the details inside and outside the row of ampoule bottles.

The input ends of the two first vertical conveying belts 421 extend respectively to the second flip output ends 4122 close to the two second flip conveying belts 412.

[0065] The second upright conveying part includes two second upright conveying belts 422, and the two second upright conveying belts 422 form a conveying gap for clamping and conveying the tails of the upright row of ampoule bottles. The input end and the output end of the second upright conveying belt 422 are both axially arranged vertically. The input sections of the two second upright conveying belts 422 extend to the bottom of the output ends of the two first upright conveying belts 421, respectively, to achieve the docking of the first upright conveying part and the second upright conveying part.

[0066] There are three image acquisition components 6 located at the flip conveying mechanism, two of which are located at the first upright conveying part, and one is located at the second upright conveying part. The cameras 61 of the two image acquisition components 6 located at the first upright conveying part are respectively located on the side of the two first upright conveying belts 421 that are away from each other and are both set toward the conveying path of the row of ampoule bottles. The image acquisition component 6 located at the second upright conveying part is located on one side of the second upright conveying belt 422 and the camera 61 of the image acquisition component 6 there is set toward the conveying path of the row of ampoule bottles.

[0067] Specifically, the camera 61 located at the first upright conveying part is used to capture the image of the upright row of ampoule bottles and feed it back to the control module so that the control module can determine whether there are defects in the body and tail of the ampoule bottle, and whether there are floating impurity particles and precipitated impurities in the liquid in the body of the row of ampoule bottles.

[0068] The camera 61 located at the second upright conveying part is used to capture the image of the upright row of ampoule bottles and feed it back to the control module so that the control module can determine whether there are defects in the ampoule bottle body and bottle head, and whether there are floating impurity particles and precipitated impurities in the liquid in the row of ampoule bottles.

[0069] The tilted stacked ampoule bottles are flipped to an upright state by the flipping conveying assembly 41. When there are foreign particles in the stacked ampoule bottles, the fluidity of the foreign particles in the liquid in the stacked ampoule bottles is improved, so that they can be better captured by the image acquisition assembly 6. The first upright conveying part and the second upright conveying part clamp and convey the bottle head and bottle tail of the stacked ampoule bottles respectively, so that the bottle head and bottle tail of the stacked ampoule bottles can leak out alternately, so that the corresponding image acquisition assembly 6 can more completely acquire the image of the stacked ampoule bottles.

[0070] The overturning conveying mechanism also includes a supporting conveyor belt 43, which is used to support and convey the upright row of ampoule bottles. The input end of the supporting conveyor belt 43 extends to the bottom of the output ends of the two second overturning conveyor belts 412, and the output end of the supporting conveyor belt 43 extends to the bottom of the input ends of the two first upright conveyor belts 421. The use of the supporting conveyor belt 43 to assist in conveying the upright row of ampoule bottles is conducive to better connecting the unpowered area between the second overturning conveying part and the first upright conveying part, thereby facilitating the upright row of ampoule bottles output by the second overturning conveying part to be better transferred to the first upright conveying part.

[0071] Reference Figure 8 and Fig. 9 The discharging conveying mechanism 5 includes a discharging conveying belt 51; the input end of the discharging conveying belt 51 extends to the bottom of the output end of the two second upright conveying belts 422. A material-removing assembly 50 is provided at the input end of the discharging conveying belt 51, and the material-removing assembly 50 includes a material-removing limiting rod 501, a material-removing air knife 502 and a material-removing collection box 503. The material-removing limiting rod 501 is supported above the discharging conveying belt 51 and leaves a gap with the conveying surface of the discharging conveying belt 51. The inlet end of the material-removing limiting rod 501 extends to the output end of the second upright conveying part, and is used for overlapping the bottle heads of the upright row of ampoule bottles output by the second upright conveying part. The material-removing air knife 502 and the material-removing collection box 503 are respectively located on opposite sides of the discharging conveying belt 51, and the material-removing air knife 502 is arranged toward the gap between the material-removing limiting rod 501 and the discharging conveying belt 51. The material-removing air knife 502 is electrically connected to the control module.

[0072] The control module determines the qualified status of the row of ampoule bottles according to the image acquisition components 6 at each location. When the unqualified row of ampoule bottles is transmitted to the rejecting limit rod 501, the control module controls the rejecting air knife 502 to blow the unqualified row of ampoule bottles into the rejecting collection box 503, so as to automatically reject the unqualified row of ampoule bottles. In this embodiment, the opening and closing of the rejecting air knife 502 is completed by the control module in conjunction with the sensor.

[0073] The discharge conveyor belt 51 is also supported by a second guide member 52, and the input end of the second guide member 52 extends to the output end of the material removal limit rod 501. There is a gap between the output end of the second guide member 52 and the output end of the discharge conveyor belt 51. The second guide member 52 includes two second guide plates arranged in parallel, and the two second guide plates form a conveying gap for the upright row of ampoule bottles to pass through. The subsequent qualified upright row of ampoule bottles enter the conveying gap between the two second guide plates through the material removal limit rod 501 under the conveyance of the discharge conveyor belt 51, and then automatically swing down to transition to a horizontal state after being transmitted through the two second guide plates.

[0074] Reference Figure 8 and Fig.10The output end of the discharge conveyor belt 51 is connected with the rear-end packaging equipment used in conjunction with the BFS product automatic light inspection machine. A transition plate 8 is supported at the output end of the discharge conveyor belt 51. The transition plate 8 extends to the conveying plane of the discharge conveyor belt 51 and the transition plate 8 is arranged flush with the conveying plane of the discharge conveyor belt 51. The arrangement of the transition plate 8 facilitates the row of ampoules on the discharge conveyor belt 51 to be better output to the output end of the discharge conveyor belt 51.

[0075] An auxiliary conveyor belt 81 is also supported on the output end of the discharge conveyor belt 51. One end of the auxiliary conveyor belt 81 extends above the transition plate 8. The auxiliary conveyor belt 81 and the transition plate 8 form a conveying gap for clamping and conveying the row of ampoule bottles. The auxiliary conveyor belt 81 is arranged to facilitate better conveying the row of ampoule bottles conveyed to the transition plate 8 by the discharge conveyor belt 51 to the outside of the transition plate 8, thereby reducing the accumulation of the row of ampoule bottles in the unpowered area of ​​the transition plate 8, which causes the accumulation of materials at the output end of the discharge conveyor belt 51.

[0076] The input end of the inverted conveying mechanism 2 and the input end of the first upright conveying part are both supported with a defoaming part, the defoaming part is located on one side of the conveying path of the row of ampoule bottles, and the defoaming part includes a defoaming cylinder 7, the defoaming cylinder 7 is arranged toward the conveying path of the row of ampoule bottles, and the piston rod of the defoaming cylinder 7 is coaxially connected with a defoaming rod 71. The defoaming cylinder 7 is electrically connected to the control module.

[0077] When the row of ampoules is delivered to the defoaming cylinder 7, the control module controls the defoaming cylinder 7 to drive the defoaming rod 71 to hit the row of ampoules back and forth to eliminate bubbles in the ampoules and reduce the interference of bubbles in the subsequent control module in judging whether the ampoules are qualified.

[0078] The implementation principle of the embodiment of the present application is that after the inverted row of ampoule bottles are introduced into the BFS light inspection machine through the feeding conveying structure, the row of ampoule bottles are transported through the inverted conveying mechanism 2, the inclined conveying mechanism 3 and the upright conveying mechanism 4, and the row of ampoule bottles in the inverted state are gradually transitioned to the inclined state and the upright state; preferably, they are transmitted through the discharging conveying mechanism 5. During this period, the camera 61 at each of the inverted conveying mechanism 2, the inclined conveying mechanism 3 and the upright conveying mechanism 4 takes the image of the row of ampoule bottles in the corresponding posture and feeds it back to the control module, and the control module determines whether the row of ampoule bottles is qualified according to the feedback image; when the unqualified row of ampoule bottles are output to the rejecting air knife 502 through the discharging conveying belt 51, the rejecting air knife 502 blows it out from the discharging conveying belt 51, so as to realize the automatic rejection of the unqualified row of ampoule bottles.

[0079] The inverted conveying mechanism 2, the inclined conveying mechanism 3 and the upright conveying mechanism 4 are used to gradually transition the row of ampoules from an inverted state to an inclined state and an upright state, so that the camera 61 at the image acquisition component 6 can more clearly and completely see the inside and outside conditions of the row of ampoules, which is beneficial for the subsequent control module to better judge whether the row of ampoules is qualified.

[0080] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
