Abstract

A laser drilling and inspection machine allowing for automatic flipping. A flipping device (2000) is located in a flipping station area and is used for carrying out flipping processing on at least some target objects reaching the flipping station area, so that the target objects in a back side up state appear in a front side up state; a drilling device (3000) is located in a drilling station area and is used for carrying out drilling processing on target objects reaching the drilling station area. According to the laser drilling and inspection machine allowing for automatic flipping and a drilling method, although target objects appear in both the front side up state and the back side up state when supplied to an initial station area, after a conveying device conveys all the target objects to the flipping station area, the flipping device (2000) will recognize the target objects in the back side up state and specifically carry out flipping processing on the target objects in the back side up state, so as to make preparation for drilling processing. After all the target objects are conveyed to the drilling station area, the drilling device (3000) can directly carry out drilling processing on the target objects, thereby improving the drilling efficiency for the target objects.

Description

Automatic flip laser punching inspection machine and punching method Technical Field

[0001] The present application relates to the field of pharmaceutical technology, and in particular to an automatic sheet-turning laser punching inspection machine and a punching method. Background Art

[0002] Osmotic pump tablets can be manufactured using the osmotic principle to deliver slow-release oral medications, evenly releasing drugs in the body over a long period of time. These tablets are encased in a semipermeable membrane with small laser-perforated holes. After oral administration, water in the body enters the tablet through the membrane, dissolving the drug or osmotic pressure generator and generating osmotic pressure, which continuously releases the drug. These tablets are also known as osmotic pump tablets. There are several types of osmotic pump tablets, including single-chamber and dual-chamber osmotic pump tablets.

[0003] The osmotic pressure generator of a single-chamber osmotic pump tablet is mixed with the drug, and there is no need to distinguish the tablets by the front and back sides. A small hole is punched on both sides of the tablet so that the drug can be released. A dual-chamber osmotic pump tablet has a two-layer structure, with one layer being a drug reservoir and the other layer being an osmotic pressure generator. The osmotic pressure generator absorbs water and swells, generating a driving force that pushes the drug out of the small hole. Therefore, for this type of controlled-release tablet, a small hole must be punched on the coating layer side of the drug reservoir, otherwise the drug cannot be released. The current punching efficiency of the punching device for dual-chamber osmotic pump tablets is low, which cannot meet the needs of industrial production and the demand for drug release. Therefore, improving the punching efficiency of dual-chamber osmotic pump tablets has become a technical problem that needs to be solved urgently in this area.

[0059] The present application provides an automatic flip laser drilling inspection machine. Referring to Figures 1 to 4 , the automatic flip laser drilling inspection machine may include a transport device 1000, a flipping device 2000, and a drilling device 3000. Furthermore, the automatic flip laser drilling inspection machine may also be equipped with a return device 4000 and one or more screening devices 5000, as needed. This automatic flip laser drilling inspection machine can be used for drilling targets such as dual-chamber osmotic pump tablets. As can be seen, dual-chamber osmotic pump tablets have a two-layer structure. As shown in Figure 2 , the dual-chamber osmotic pump tablet includes one shaded area and one unshaded area, representing one layer of the dual-chamber osmotic pump tablet containing a drug reservoir and the other layer containing an osmotic pressure generator. The holes are to be drilled in the coating layer of the drug reservoir. Therefore, for ease of describing the technical solution, the front-side-up state of the target object refers to the drug reservoir side of the dual-chamber osmotic pump tablet, represented by the unshaded side, and the reverse-side-up state refers to the drug reservoir side of the dual-chamber osmotic pump tablet, represented by the shaded side. In addition, those skilled in the art can also apply the automatic flip laser drilling inspection machine to other drilling scenarios according to needs, which is not limited here.

[0060] The transport device 1000 is a device for transporting target objects. The transport device 1000 may be pre-defined with a clear transport trajectory 1000a, which may include at least an initial work area, a flipping work area, a punching work area, and a finished product work area. The transport device 1000 is configured to transport the target objects along the transport trajectory 1000a, allowing the target objects located in the initial work area to be actively transported by the transport device 1000 and sequentially passed through the flipping work area, the punching work area, and the finished product work area, with each work area providing the target objects with different targeted processing operations. Therefore, the transport track 1000a is pre-fixed on the transport device 1000, and the multiple workstations such as the initial workstation, flipping workstation, punching workstation and finished product workstation are also fixed in position on the transport track 1000a. The function of the transport device 1000 is to drive the target object along the transport track 1000a so that the target object moves relative to multiple different workstations, thereby passing through the initial workstation, flipping workstation, punching workstation and finished product workstation in turn.

[0061] The transport device 1000 may include a transport platform 1100, which may include a plurality of receiving slots 1100a. The receiving slots 1100a are used to receive target objects, so that the target objects can be regularly arranged on the transport platform 1100 based on a preset distribution rule of the receiving slots 1100a. The receiving slots 1100a include interconnected receiving hole sections 1120a and airflow hole sections 1110a. The aperture size of the airflow hole section 1110a is larger than the aperture size of the receiving hole section 1120a, so that the aperture size of the receiving hole section 1120a allows the target object to enter, while the aperture size of the airflow hole section 1110a prohibits the target object from entering, thereby confining the target object within the receiving hole section 1120a. Therefore, the receiving slot 1100a can primarily receive the target object through the space of the receiving hole section 1120a.

[0062] In one embodiment, the transport platform 1100 may further include a base platform 1110 and a moving platform 1120, the accommodating hole section 1120a is opened on the moving platform 1120, the air flow hole section 1110a is opened on the base platform 1110, and the driving device 1200 is arranged on the base platform 1110, and the driving device 1200 is used to drive the moving platform 1120 to rotate relative to the base platform 1110, so that different accommodating hole sections 1120a can be connected to different air flow hole sections 1110a in sequence.

[0063] For example, during the rotation of the moving platform 1120, the accommodating hole segment 1120a on the moving platform 1120 will also rotate accordingly. When one or some of the accommodating hole segments 1120a pass through multiple work areas such as the initial work area, the flipping work area, the return work area, the punching work area, the screening work area and the finished product work area, the accommodating hole segment 1120a will form an upper and lower position correspondence with the accommodating hole segments 1120a located in different work areas among the initial work area, the flipping work area, the return work area, the punching work area, the screening work area and the finished product work area, thereby forming corresponding mutual connections.

[0064] Therefore, as the moving platform 1120 in the transport platform 1100 rotates relative to the base platform 1110, each receiving hole segment 1120a can sequentially pass through the initial work area, the flipping work area, the return work area, the punching work area, the screening work area, and the finished product work area along the transport track 1000a, thereby moving the target object within the receiving hole segment 1120a along the transport track 1000a. The moving platform 1120 can be provided with two or more receiving hole segments 1120a in a direction perpendicular to the transport track 1000a, and the base platform 1110 can also be provided with two or more corresponding airflow hole segments 1110a in a direction perpendicular to the transport track 1000a. This allows two or more receiving hole segments 1120a to pass through various work areas simultaneously, allowing two or more target objects to be processed simultaneously in different work areas.

[0065] In one embodiment, the transport track 1000a may adopt a circular track having a central axis, and the driving device 1200 is used to drive the motion platform 1120 to rotate along the central axis. For example, the driving device 1200 is a rotating motor, and the rotating motor drives the motion platform 1120 to rotate along the central axis. The transport platform 1100 may be circular or non-circular, as long as it can drive the target object to move along the circular track. In this way, each accommodating hole section 1120a can pass through the initial work area, the flipping work area, the return work area, the punching work area, the screening work area and the finished product work area in sequence along the transport track 1000a, and after a week, it can also cycle through multiple work areas such as the initial work area, the flipping work area, the return work area, the punching work area, the screening work area and the finished product work area again.

[0066] The automatic flip laser drilling inspection machine produces smoke and dust during operation, so it needs to be cleaned at the end of the work. Since the light source, camera, laser transmitter, solenoid valve and turntable in the automatic flip laser drilling inspection machine cannot be completely disassembled and cleaned, conventional cleaning is not thorough. Continuing to refer to FIG5 , in one embodiment, the transport device may include a lifting platform 1130 and a lifting mechanism 1130a. The side of the lifting platform 1130 has a circular recess 1130b. The moving platform is a circular platform. The circular platform and the circular recess 1130b are interlocked, and the moving platform 1120 can also rotate relative to the lifting platform 1130. The lifting mechanism 1130a is arranged on the base platform. The lifting mechanism 1130a is connected to the lifting platform 1130 for driving the lifting platform 1130 to rise or fall relative to the base platform.

[0067] During operation, the lifting mechanism 1130a controls the lifting platform 1130 to a height parallel to the motion platform 1120, allowing the circular platform to interlock with the circular recess 1130b. When the operation is completed, the lifting mechanism 1130a controls the lifting platform 1130 to rise above the motion platform 1120. The motion platform 1120 can then be removed and cleaned separately. The area in the automatic flip laser drilling inspection machine where the most dust accumulates is the receiving slot 1100a that holds the target object, making it a key cleaning location.

[0068] Continuing to refer to Figures 1 and 2, the flipping device 2000 is located in the flipping station area. The function of the flipping device 2000 is to flip the target objects that arrive at the flipping station area. More precisely, it flips the target objects that are in the reverse side up state, thereby making the target objects that are in the reverse side up state appear to be in the right side up state. Because when the transport device 1000 transports the target objects from the initial station area to the flipping station area, all the target objects that arrive at the flipping station area will include target objects in the reverse side up state and target objects in the right side up state. The target objects in the right side up state can be directly punched, so there is no need for flipping. Therefore, the flipping device 2000 is mainly used to flip the target objects that are in the reverse side up state.

[0069] Whether the target object is facing up or down can be identified by an identification device 6000 provided in the automatic flip laser drilling inspection machine. The identification device 6000 is configured to identify the orientation information, drilling status information, etc. of the target object as required, thereby guiding the corresponding operation of the automatic flip laser drilling inspection machine based on the acquired information. The identification device 6000 may employ a device such as a camera capable of acquiring image data to acquire the required information. For example, the identification device 6000 may include a first information acquisition device 6100, which may be a camera. The first information acquisition device 6100 is located in the flipping station area and is configured to acquire the orientation information of the target object arriving at the flipping station area. The orientation information of the target object can be used to identify whether the target object is facing up or down. The flipping device 2000 then identifies the target object arriving at the flipping station area based on the orientation information acquired by the first information acquisition device 6100 and performs flipping on the target object that is facing up.

[0070] The punching device 3000 is located in the punching station area. Its function is to perform a punching process on target objects that arrive at the punching station area. The punching device 3000 can perform a punching process on the target objects in a variety of ways. For example, the punching device 3000 can use a laser machine, such as a water-cooled 100W CO2 laser machine, as needed. This laser machine operates stably, has adjustable and displayable output power, and can meet high-volume production needs. It can also be set to automatically delay the laser machine start-up for 5 minutes after power-on, effectively protecting the laser machine and extending its service life. Because the flipping device 2000 has already flipped the target objects that are facing upside down during the process of transporting the target objects from the initial station area to the flipping station area by the transport device 1000, when the target objects that have passed through the flipping station area are transported to the punching station area, the target objects that are facing upside down are flipped to the front side up, thereby preparing them for punching.

[0071] In the above process, although the target objects are delivered to the initial working area in some states, such as the front side facing up and the back side facing up, when the transport device 1000 transports all the target objects to the flipping working area, the flipping device 2000 will identify the target objects with the back side facing up and specifically flip the target objects with the back side facing up, thus preparing for the punching process. After all the target objects have been transported to the punching working area, the punching device 3000 can directly punch the target objects, greatly improving the punching efficiency of the target objects and meeting industrial requirements.

[0072] In addition, in one embodiment, the automatic flipping laser drilling inspection machine also includes a return device 4000. Therefore, the transport track 1000a may include a return station area, located between the flipping station area and the punching station area. The return device 4000 is located in the return station area and functions to return objects that arrive at the return station area. After the transport device 1000 transports the objects from the initial station area to the flipping station area, the flipping device 2000 will flip the objects that are facing up. However, given the flipping success rate of the flipping device 2000, some objects may be transported to the punching station area without being flipped or without being successfully flipped. Therefore, a return station area is constructed between the flipping station area and the punching station area, and the return device 4000 is used to re-inspect all objects that arrive at the return station area.

[0073] Regarding the review of the target object, it can be identified through the identification device 6000 set in the automatic flip laser drilling inspection machine. The function of the identification device 6000 is to identify the orientation status information, drilling status information, etc. of the target object according to needs, so as to guide the corresponding operation of the automatic flip laser drilling inspection machine based on the acquired information. Among them, the recognition device 6000 can use a device such as a camera that can obtain image data to obtain the required information. For example, the recognition device 6000 includes a second information acquisition device 6200. The second information acquisition device 6200 can use a camera. The second information acquisition device 6200 is located in the return work area and is used to obtain the orientation status information of the target object arriving at the return work area. The orientation status information of the target object will identify the reverse-facing state and the front-facing state of the target object. At this time, the return device 4000 will re-identify the target object arriving at the return work area based on the orientation status information obtained by the second information acquisition device 6200. If a target object is found to be in a reverse-facing state, it will be returned for processing, so that the target object in a reverse-facing state is returned to the initial work area, and is transported again by the transportation device 1000, and moves again from the initial work area along the transportation track 1000a, and repeats the above steps.

[0074] In addition, in one embodiment, the automatic flip laser perforation inspection machine further includes at least one screening device 5000, and the transport track 1000a includes at least one screening station. For example, if there is only one screening station, it can be located between the punching station and the finished product station, and the screening device 5000 is located in the screening station. If there are two or more screening stations, multiple screening stations can also be located between the punching station and the finished product station, and the multiple screening stations are also arranged in sequence along the transport track 1000a, so that the target object can pass through each screening station in sequence.

[0075] The screening devices 5000 can be matched with the same number according to the number of screening workstations set up, so that multiple screening devices 5000 can be located in different screening workstations. The function of the screening device 5000 is to perform screening processing on the target objects that arrive at the screening workstation. Because when the transport device 1000 transports the target objects from the initial workstation to the flipping workstation and the punching workstation in sequence, and punches each target object, it is necessary to collect the punched target objects and output them as finished products in the finished product workstation. The finished product storage device 8000 can be used to receive and store the target objects that arrive at the finished product workstation.

[0076] However, due to the limited punching pass rate of the punching device 3000, not all target objects may be punched, or the punched target objects may not fully meet the punching standards. Therefore, a screening station can be constructed between the punching station and the finished product station, and the screening device 5000 can be used to review all target objects that arrive at the screening station.

[0077] The target objects can be reviewed using an identification device 6000 provided in the automatic flip laser drilling inspection machine. The identification device 6000 is configured to identify the target object's orientation status information, drilling status information, and other information as needed, thereby guiding the automatic flip laser drilling inspection machine's corresponding operations based on the acquired information. The identification device 6000 can acquire the required information using a device such as a camera capable of acquiring image data. For example, the identification device 6000 includes a third information acquisition device 6300, which can be a camera. The third information acquisition device 6300 is located in the screening station area and is used to acquire drilling status information of the target objects that arrive at the screening station area. The drilling status information of the target objects can indicate whether the target object has been drilled, whether the size of the drilling meets the standard, whether the drilling position is offset from the center, and so on. This information can be compared with the drilling standard to screen out unqualified target objects that do not meet the drilling standard.

[0078] At this time, the screening device 5000 will re-identify the target objects arriving at the screening station area based on the punching status information obtained by the third information acquisition device 6300. If unqualified target objects that do not meet the punching standards are found, they will be screened out.

[0079] The flipping process of the flipping device 2000, the return process of the return device 4000, and the screening process of the screening device 5000 can all be implemented in a variety of ways, such as robotic arm grasping, fluid impact, and other feasible methods. In one embodiment, the flipping device 2000, the return device 4000, and the screening device 5000 of the present application can all implement corresponding processes based on pneumatic principles. As shown in Figure 2, in one embodiment, each receiving slot 1100a can include an air flow hole section 1110a and a receiving hole section 1120a. When the transport platform 1100 is designed as a detachable structure including a base platform 1110 and a moving platform 1120, the receiving hole section 1120a is opened on the moving platform 1120, and the air flow hole section 1110a is opened on the base platform 1110. The shape of the air flow hole section 1110a is not limited, as long as it ensures that the air flow can pass through stably and that the target object does not fall from the air flow hole section 1110a.

[0080] Based on the airflow hole segment 1110a, airflow can be applied to the target object, causing the target object to be reversed or shifted. For example, in one embodiment, the flipping device 2000 includes a first fluid control device 2100. The first fluid control device 2100 is used to apply positive pressure driving gas or negative pressure driving gas to the target object located in the receiving slot 1100a through the airflow hole segment 1110a. Depending on the position and angle of application, the target object is turned from a reverse-side-up state to a right-side-up state in the receiving slot 1100a. For example, during the flipping process, applying positive pressure driving gas or negative pressure driving gas to the target object can cooperate with the centrifugal force during the movement of the target object. When the transport trajectory 1000a adopts a circular trajectory, the transport device 1000 will drive the target object to rotate along the circular trajectory. In this process, the target object can generate outward centrifugal force and forward impulse along the circular trajectory. At this time, the first fluid control device 2100 can apply positive pressure driving gas or negative pressure driving gas to the target object located in the receiving slot 110a through the air flow hole section 1110a. By setting the positive pressure driving gas or negative pressure driving gas to be applied at a certain time, a certain angle, and a certain size, the target object can be quickly and accurately flipped over, and the flipping success rate is also high. Parameters such as the application force of the positive pressure driving gas or the negative pressure driving gas can be controlled by a solenoid valve and a logic controller. Those skilled in the art can set it according to actual needs and are not limited here.

[0081] Continuing with FIG. 3 , in one embodiment, the return device 4000 includes a return pipe 4100 and a second fluid control device 4200. The input pipe opening of the return pipe 4100 communicates with the return workstation, while the output pipe opening of the return pipe 4100 communicates with the initial workstation. One or more return pipes 4100 can be provided, and as needed, the input pipe openings of the return pipe 4100 can be fixedly aligned with positions through which the receiving slot 1100a can pass. This ensures that when the transport device 1000 transports a target object within the receiving slot 1100a, the input pipe opening of the return pipe 4100 is precisely connected to the receiving slot 1100a. When the corresponding target object needs to be returned, the second fluid control device 4200 can be used to apply positive pressure driving gas to the target object located in the accommodating slot 1100a through the air flow hole section 1110a. The positive pressure driving force can force the target object to leave the accommodating slot 1100a, and then move along the return pipe 4100, so that the target object returns to the initial work station area through the return pipe 4100.

[0082] Continuing with FIG. 3 , in one embodiment, the screening device 5000 includes a screening conduit 5100 and a third fluid control device 5200 . The input conduit port of the screening conduit 5100 communicates with the screening station area, and the output conduit port of the screening conduit 5100 communicates with the screening storage bin. One or more screening conduits 5100 can be provided, and the input conduit ports of the screening conduits 5100 can be fixedly aligned with positions where the storage slot 1100a can pass, as needed. This ensures that when the transport device 1000 transports a target object within the storage slot 1100a, the input conduit port of the screening conduit 5100 can be precisely connected to the storage slot 1100a. When the corresponding target object needs to be screened, the third fluid control device 5200 can be used to apply positive pressure driving gas to the target object located in the accommodating slot 1100a through the air flow hole section 1110a. The positive pressure driving force can force the target object to leave the accommodating slot 1100a, and then move along the screening pipe 5100, so that the target object enters the screening accommodating bin through the screening pipe 5100.

[0083] Continuing with reference to FIG. 1 and FIG. 6 , in one embodiment, the automatic flip laser perforation inspection machine includes a loading device 7000 , which includes a feed bin 7100 , which has a feed cavity inside and an open window at the bottom thereof that communicates with the feed cavity. The feed bin 7100 can position the open window opposite the transport platform 1100 of the transport device 1000 , and the open window can cover the initial workstation area, which can cover the entire initial workstation area or at least a portion of the initial workstation area. The loading device 7000 can be equipped with a pushing mechanism for introducing the target object into the receiving slot 1100 a , for example, the pushing mechanism includes a brush that can sweep the target object. In addition, those skilled in the art can also provide a similar mechanism capable of pushing the target object, as long as it can actively introduce the target object into the receiving slot 1100 a , and this is not limited here.

[0084] Therefore, after the target object falls into the feed bin 7100, the equipped pushing mechanism can actively guide the target object into the receiving slot 1100a, ensuring that the target object is accurately positioned in each fixed receiving slot 1100a after being introduced into the receiving slot 1100a, and then moved to the flipping station area. The target object is positioned in each fixed receiving slot 1100a, which facilitates subsequent flipping, return processing, punching processing, and screening processing.

[0085] Referring to Figure 6, the loading device 7000 may also include a storage hopper 7200 and a weight sensor 7200a. The storage hopper 7200 is used to store the target object and apply the target object to the supply bin 7100, so the storage hopper 7200 needs to be connected to the supply bin 7100. For example, the storage hopper 7200 is located above the supply bin 7100, and automatically applies the target object to the supply bin 7100 through gravity, or actively transports the target object to the supply bin 7100 through other mechanical structures. This is not limited here.

[0086] The storage hopper 7200 can be assembled and fixed via a support frame 7200b. An assembly element 7200c can be provided on the storage hopper 7200, and the storage hopper 7200 is assembled to the support frame 7200b via the assembly element 7200c. A weight sensor 7200a is provided on the storage hopper 7200 and is used to detect the weight of the target objects within the storage hopper 7200. Therefore, when the number of target objects within the storage hopper 7200 changes, the gravity sensor detects a change in the total weight of the target objects. When the weight is less than a preset value, target objects can be automatically added to the storage hopper 7200 using an adapted filling device, or target objects can be added manually, without limitation herein.

[0087] The present application provides a punching method, which includes the following steps: transporting a target object along a transport track 1000a, wherein the transport track 1000a includes at least an initial work station area, a flipping work station area, a return work station area, a punching work station area, a screening work station area, and a finished product work station area, so that the target object located in the initial work station area passes through the flipping work station area, the return work station area, the punching work station area, the screening work station area, and the finished product work station area in sequence.

[0088] At least a portion of the target objects arriving at the flipping station area are flipped over so that the target objects in the reverse side facing up state are presented in the front side facing up state, and then the target objects arriving at the punching station area are punched; wherein, if the target objects arriving at the return station area are in the reverse side facing up state, they are returned so that the target objects in the reverse side facing up state are returned to the initial station area, and if the target objects arriving at the screening station area do not meet the punching standards, they are screened out.

[0089] In the aforementioned punching method, although the target objects are delivered to the initial workstation in both front-side-up and back-side-up states, once the transport device 1000 has transported all the target objects to the flipping workstation, the flipping device 2000 identifies the target objects with the back-side-up state and specifically flips them over, thereby preparing them for punching. Once all the target objects have been transported to the punching workstation, the punching device 3000 can directly punch the target objects, significantly improving the punching efficiency and meeting industrial requirements. Furthermore, before punching, the target objects are reviewed to prevent punching of target objects with the back-side-up state. At least one review is also conducted before collecting the finished target objects to prevent collection of those that do not meet the punching standards. This method ensures a 100% yield and effectively improves the punching efficiency of the target objects.

[0090] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
