Description

Technical Field

[0001] This invention relates to the field of automated equipment, and more specifically to an inner shell inspection and transfer device. Background Technology

[0002] As a core product in the CGM (Continuous Glucose Monitoring) industry, the demand for blood glucose monitoring sensors is rapidly increasing with the growing health management needs of diabetic patients, placing higher demands on the product's production capacity and efficiency.

[0003] Currently, the assembly process of blood glucose monitoring sensors is still mainly manual, with the inspection of the inner shell being a crucial step to ensure the smooth assembly and quality of the final product. The core steps of inner shell inspection include loading, positioning, inspection, transfer, and unloading of the sensor inner shell. Manual assembly not only suffers from high labor costs and low production efficiency, but is also prone to insufficient assembly precision and increased appearance defects due to human error, making it difficult to meet the consistency and stability requirements of large-scale production. Furthermore, the lack of continuity in manual operation prevents 24-hour uninterrupted production, hindering further capacity increases and failing to meet surging market demand.

[0004] To address the production capacity gap following the launch of new products, reduce labor costs, and improve the level of automated assembly, some semi-automated equipment has emerged on the market. However, these existing semi-automated equipment often suffer from limited functionality and poor process integration. For example, some equipment can only perform simple feeding or inspection functions and cannot complete the integrated operation from automatic feeding, accurate receiving, cyclic transfer, visual inspection to qualified unloading and NG material diversion. Although semi-automation has been achieved, the demand for human intervention is still relatively high, the efficiency still cannot meet the actual needs, and it cannot achieve efficient docking with subsequent assembly stations, thus limiting the overall automation upgrade of the production line.

[0005] Therefore, developing a highly efficient inner shell inspection and transfer device that can cover the entire process of automatic feeding, receiving, transfer, inspection, unloading, and NG diversion has become an important issue that urgently needs to be addressed by those skilled in the art.

[0017] Compared with the prior art, the beneficial effects of the present invention are: The inner shell inspection and transfer device provided in this case achieves a fully automated closed-loop process for inner shell inspection, covering the entire process of feeding, receiving, transfer, inspection, qualified material unloading, NG material diversion, and material supply to the next process, significantly improving production capacity and efficiency while reducing labor costs. Specifically, the automatic feeding machine realizes automatic material feeding, the receiving and feeding mechanism realizes automatic material receiving and feeding, and the material transfer mechanism achieves precise connection between each process, ensuring the consistency of material transportation. The high-precision judgment of the vision inspection mechanism overcomes the error of human judgment. The Z-axis linear mold 5 drives the unloading and receiving platform to move back and forth, accurately picking up qualified materials and simultaneously providing precise material supply for subsequent inner and outer shell assembly processes, improving the compatibility of the equipment with the production line.

[0023] The following examples further illustrate the features and other related characteristics of the present invention in detail, to facilitate understanding by those skilled in the art: For ease of description and understanding, please refer to the attached diagram for descriptions related to positional relationships such as front, back, top, bottom, left, right, outside, and inside, as well as descriptions related to X, Y, and Z axis directions.

[0024] The core of a continuous glucose monitor (CGM) consists of signal acquisition, processing and transmission, power supply and protection, and fixed auxiliary components. Specifically, it includes a flexible probe integrating working and reference electrodes, a signal conditioning chip, a microcontroller (MCU), a low-power wireless communication module (Bluetooth / NFC), a micro battery, an inner shell and an outer shell, biocompatible adhesive, and auxiliary components such as a temperature compensation sensor, sealing gaskets, and activation switches, which work together to achieve continuous acquisition, processing, transmission and accurate monitoring of blood glucose signals.

[0025] Reference Figures 1-5 As shown, the inner shell inspection and transfer device provided in this case generally performs appearance inspection on material 500 (inner shell) to ensure that it meets the assembly requirements of the next process and the outer shell, and transfers it to the next process for assembly with the outer shell.

[0026] The inner shell inspection and transfer device provided in this case includes an automatic feeder 100 and an inner shell inspection and transfer machine 200 connected to the right side of the automatic feeder 100 to receive materials from the upper end of the automatic feeder 100. The automatic feeder 100 continuously provides materials 500 for subsequent processes, replacing manual feeding operations, avoiding the problems of low efficiency and messy material placement caused by manual feeding, ensuring continuous feeding, and laying the foundation for subsequent processes. The inner shell inspection and transfer machine 200 is used for the transfer, inspection, and unloading of the inner shell. Specifically, the inner shell inspection and transfer machine 200 includes a receiving and feeding mechanism 1 connected to the automatic feeder 100, a material transfer mechanism 2 connected to the right side of the receiving and feeding mechanism 1, a vision inspection mechanism 3 connected to the front of the material transfer mechanism 2, an unloading receiving platform 4 set on the right side of the material transfer mechanism 2, a Z-axis linear module 5 connected to the lower end of the unloading receiving platform 4 for driving the movement of the unloading receiving platform 4, and an NG unloading station 6 connected to the rear end of the material transfer mechanism 2. The material receiving and feeding mechanism 1 connects the automatic feeder 100 and the material transfer mechanism 2, enabling a smooth transition of material 500 from the supply end to the transfer end, while simultaneously completing the initial positioning of the material. This solves the problem of material 500 easily falling or shifting during transfer between equipment, ensuring the accuracy of material 500 transfer and guaranteeing the stability of subsequent inspection and clamping. The material transfer mechanism 2 drives material 500 sequentially through each workstation, achieving orderly connection of multiple processes, replacing manual handling and workstation switching, ensuring the positioning accuracy of each process, improving transfer efficiency, and forming a closed-loop process. Specifically, the material transfer mechanism 2 connects to the material receiving and feeding mechanism 1 on the left, corresponds to the vision inspection mechanism 3 in front, connects to the unloading and receiving platform 4 on the right, and connects to the NG unloading station 6 at the rear, linking and matching with each mechanism and connecting all processes in series. The visual inspection mechanism 3 is used to inspect the material 500 transferred from the material transfer mechanism 2. It checks the appearance defects (damage, burrs, etc.), orientation, and dimensional consistency of the inner shell transferred to the inspection station, outputting a pass or fail signal. This replaces manual visual inspection, improving inspection accuracy and efficiency, avoiding human error, and ensuring consistent product quality. The unloading and receiving platform 4 specifically receives the material 500 that has passed the visual inspection mechanism 3. The Z-axis linear module 5 drives the unloading and receiving platform 4 to move forward to receive materials and backward to transport materials, thus supplying materials for the next inner and outer shell assembly process. The combined operation of the unloading and receiving platform 4 and the Z-axis linear module 5 achieves precise receiving and directional transport of the passed material 500, adapting to subsequent assembly needs (such as robotic gripping) and improving the efficiency of docking with the next process. The fail unloading station 6 is used for the unqualified material 500 transferred from the material transfer mechanism 2 that has been inspected by the visual inspection mechanism 3, to separate qualified and fail materials, avoid mixing, and facilitate centralized processing of fail materials. The inner shell inspection and transfer machine 200 also includes a loading and unloading pushing mechanism 7 disposed on the upper end of the material transfer mechanism 2 and an NG pushing mechanism 8 connected to the upper end of the loading and unloading pushing mechanism 7.The loading and unloading pushing mechanism 7 can simultaneously perform loading and unloading operations on the material transfer mechanism 2, simplifying the equipment structure, reducing manufacturing costs, minimizing redundant actions, and improving production efficiency. The NG pushing mechanism 8 is used to transfer NG materials from the material transfer mechanism 2 to the NG unloading station 6. When the NG pushing mechanism 8 receives an NG signal, it pushes the non-conforming materials into the NG unloading station 6, achieving automatic diversion without manual intervention and improving screening efficiency. The inner shell detection and transfer device provided in this case has a compact structure and reasonable layout. The components work together to achieve full automation of the material process from automatic loading to final unloading, greatly improving detection accuracy and production efficiency.

[0027] Specifically, refer to Figures 1-2 As shown, the automatic feeding machine 100 of this invention includes a feeding hopper 101 and a vibrating plate 102 disposed below the feeding hopper 101. In specific implementation, from... Figure 1 , Figure 2 As can be seen, the feeding hopper 101 in this case is designed to be relatively large to accommodate more material and avoid frequent manual material addition. The vibratory feeder 102 includes a vibratory feeder body 103, a hopper 104 installed above the vibratory feeder body 103, a spiral track 105 extending upward along the wall of the hopper 104, a linear guide rail 106 connected to the end of the spiral track 105, a linear feeder 107 connected to the lower end of the linear guide rail 106, and a first sensor 108 suspended above the hopper 104. The right end of the linear guide rail 106 is connected to the receiving and feeding mechanism 1. Through the vibration of the vibratory feeder body 103, the material in the hopper 104 is driven to rise orderly along the spiral track 105, and the material is sorted to ensure its uniform direction. This replaces manual material sorting, realizes automatic sorting and directional conveying of materials, solves the problem of feeding jams caused by messy materials, and improves the continuity and regularity of feeding. In specific implementation, the linear guide 106 is a long, grooved guide rail that connects to the end of the spiral track 105, with its right end connected to the material receiving and feeding mechanism 1. The inner wall of the track is smooth to ensure the stability of the material during conveying. The linear feeder 107 is installed at the lower end of the linear guide 106 and is specifically an electromagnetic vibrating feeding structure with an adjustable vibration frequency. Through continuous vibration, it provides forward driving force for the material in the linear guide 106, preventing the material from getting stuck and accumulating in the linear guide 106, ensuring continuous conveying of the material in the linear guide 106, and adapting to the feeding speed of the vibrating plate 102. The feeding hopper 101 includes a feeding guide 1011 set above the hopper 104, through which the material is smoothly introduced into the hopper 104 of the vibrating plate 102. In specific implementation, the first sensor 108 is used to detect whether there is material in the hopper 104, the amount of material, and whether there is jamming or blockage, to ensure the stability of material conveying.

[0028] Reference Figure 1-4As shown, the material receiving and feeding mechanism 1 provided in this case includes a receiving platform 11 connected to the right end of the automatic feeder 100, a second sensor 12 suspended on the receiving platform 11, and a first cylinder 13 connected to the receiving platform 11. The first cylinder 13 is used to lift the receiving platform 11 to facilitate feeding the material transfer mechanism 2. The receiving platform 11 is used to receive materials conveyed by the automatic feeder 100. The first sensor 12 detects in real time whether the receiving platform 11 has received materials and accurately reached the feeding position, while simultaneously feeding back corresponding sensing signals. If the materials are accurately in place, the first cylinder 13 is triggered, realizing automatic detection of material arrival and avoiding the cylinder operating idly when there is no material or failing to feed in time when there is material, ensuring that the feeding rhythm matches the cyclic rhythm of the material transfer mechanism 2. When the first cylinder 13 receives the material arrival signal from the second sensor 12, it actuates to lift the receiving platform 11, making the receiving guide 15 level with the fixture of the material transfer mechanism 2, facilitating material feeding by the loading and unloading pushing mechanism 7. After feeding is completed, the receiving platform 11 is driven to reset to receive the next batch of material. The lifting action of the first cylinder achieves height matching between the receiving platform 11 and the material transfer mechanism 2, solving the material jamming problem that may occur during horizontal docking and improving the smoothness and accuracy of feeding. Baffles 14 are provided on the front and rear sides of the receiving platform 11, and the receiving guide 15 is formed between the two baffles 14. The baffles 14 limit the movement range of the material and prevent the material from scattering. The receiving guide 15 guides the material to accurately enter the material transfer mechanism, ensuring the alignment accuracy, stability and accuracy of the material and the material transfer mechanism 2. In other words, in specific implementation, the receiving guide 15 is flush with the linear guide 106, while the material transfer mechanism 2 is one reference position lower than the linear guide 106. When the second sensor 12 senses that the material on the receiving platform 11 has arrived, the first cylinder 13 lifts the receiving platform 11 to align the material with the material transfer mechanism 2, facilitating material supply to the material transfer mechanism 2. Simultaneously, the first cylinder 13 lifts the receiving platform 11 and blocks the incoming material on the linear guide 106, thereby achieving material cutting and preventing material accumulation or disorder on the receiving platform 11, ensuring the accuracy and orderliness of material supply. The receiving and feeding mechanism 1 in this case achieves automated material cutting and supply, improving production efficiency.

[0029] Continue to refer to Figure 1-4As shown, the material transfer mechanism 2 of this case includes a first base 21, a first motor 22 mounted on the first base 21, a turntable 23 mounted on the first motor 22 and rotatable under the drive of the first motor 22, and a fence 24 surrounding the turntable 23. At least four material clamps 25 are equidistantly installed on the turntable 23 in a circumferential direction. The first base 21 serves to support the first motor 22, the turntable 23, and the fence 24, providing a stable support foundation and absorbing operational vibrations. In specific implementation, the first motor 22 is a stepper motor. The first motor 22 drives the turntable 23 to rotate intermittently at a preset angle, causing the material clamps 25 to sequentially pass through the receiving, inspection, unloading, and NG unloading stations in a continuous cycle, ensuring the indexing accuracy and rotational stability of the turntable 23. The intermittent rotation adapts to the working time of each station, achieving orderly connection of multiple processes. The first motor 22 provides power to the turntable 23, and the turntable 23 provides a mounting carrier for the material clamps 25. The two move synchronously, and their rotation rhythm is linked with the preceding and following process mechanisms. The enclosure 24 includes notches 241 corresponding to the positions of the material receiving and loading mechanism 1, the material unloading platform 4, and the NG unloading station 6. It should be noted that the enclosure 24 is fixedly installed on the first base 21, separate from the turntable 23, and does not rotate with the turntable 23. The enclosure 24 not only provides safety protection but also resists the centrifugal force generated when the turntable 23 rotates, preventing materials from flying out during transfer. Simultaneously, it connects with the material receiving and loading mechanism 1, the material unloading platform 4, and the NG unloading station 6 through the notches 241, enabling smooth material flow. The material clamp 25 includes a first clamp base 251 and spring pieces 252 symmetrically arranged on both sides of the first clamp base 251. The spring pieces 252 on both sides provide the material clamp with a certain degree of elasticity when holding materials, ensuring the stability and reliability of the clamping. The open-type clamp is equipped with a clamping spring, which can hold the material tightly, improve the transfer accuracy and the material detection accuracy of subsequent stations. It does not require an additional drive mechanism, realizes the self-adaptive clamping of the material, has a simple structure, high clamping efficiency, and the elastic clamping can avoid damage to the material surface.

[0030] Reference Figures 1-3As shown, the visual inspection mechanism 3 of this invention includes a support rod 31, an adjustable base 32 mounted on the support rod 31, an industrial camera 33 mounted on the adjustable base 32, a micrometer 34 mounted on the side of the adjustable base 32, and a visual light source 35 mounted on the support rod 31. The visual light source 35 is mounted below the industrial camera 33 and includes a transparent portion 351. In specific implementations, the visual light source 35 is a bowl-shaped light source, and the transparent portion 351 facilitates illumination by the industrial camera 33. The industrial camera 33 in this invention is preferably a 10-megapixel industrial camera. In practical applications, the industrial camera 33 is fixed at the corresponding position on the support rod 31 and connected to the micrometer 34 via the adjustable base 32. Users can flexibly adjust the position and angle of the industrial camera according to actual inspection needs to ensure that the industrial camera 33 can capture and inspect materials from the best perspective. The micrometer 34 further improves the adjustment accuracy, making the position adjustment of the industrial camera 33 more precise and meeting the requirements of high-precision inspection. After the visual inspection agency 3 of this application completes the inspection of the material, it will provide the inspection results to provide corresponding instructions for the subsequent loading / unloading and pushing mechanism 7 and NG pushing mechanism 8 to perform corresponding operations.

[0031] The visual inspection mechanism 3 of this application achieves high-precision automated visual inspection of the inner shell through the coordinated operation of a support rod 31, an adjustable base 32, an industrial camera 33, a micrometer 34, and a vision light source 35. The support rod 31 provides stable support for the entire mechanism, effectively resisting the impact of equipment vibration on imaging accuracy. The adjustable base 32, combined with the 0.01mm-level high-precision fine adjustment of the micrometer 34, can accurately calibrate the camera's inspection field of view, ensuring the consistency and accuracy of inspection. The industrial camera 33 is a 10-megapixel high-definition model, which can clearly capture minute defects on the material surface, providing reliable image data for inspection and judgment. The vision light source 35 adopts a bowl-shaped light source design with a transparent part 351 at the bottom, which can output 360° uniform and soft light, eliminating reflections and shadows on the material surface, significantly improving image contrast and detail clarity, and helping the visual analysis system accurately determine whether the material is qualified. The components are compactly installed and smoothly linked, and the overall structure is easy to adjust and highly adaptable, further ensuring the accuracy and efficiency of the fully automated inspection process and reducing the product defect rate.

[0032] Reference Figure 1-3 , Figure 5As shown, the material receiving platform 4 in this case includes a second base 41, a second clamping seat 42 mounted on the second base 41, a second cylinder 43 mounted on the second base 41 and connected to the lower part of the second clamping seat 42, a third sensor 44 correspondingly disposed on the right side of the second clamping seat 42, and a baffle plate 45 disposed at the front end of the second clamping seat 42. The second cylinder 43 is specifically used to lift the second clamping seat 42 to receive the material conveyed by the material transfer mechanism 2. The third sensor 44 and the baffle plate 45 are both mounted on the second base 41. In specific implementation, the baffle plate 45 is used to block the notch 241 of the fence 24 corresponding to the position of the material receiving platform 4 when the material receiving platform 4 moves to receive materials, to prevent materials from accidentally falling out of the material transfer mechanism 2. After moving to the second clamping seat 42, the second cylinder 43 lifts the second clamping seat 42 so that its height is aligned with the first clamping seat 251 on the material transfer mechanism 2. Then, the loading and unloading pushing mechanism 7 operates to push the materials on the material transfer mechanism 2 onto the second clamping seat 42. After receiving the materials, it moves to the next processing step via the Z-axis linear module 5. In specific implementation, the second cylinder 43 is connected to the second clamping seat 42 through a connecting plate and a push rod. The push rod passes through the second base and is connected to the second clamping seat 42. In this embodiment, three sets of the second clamping seat 42 and the third sensor 44 are provided to meet actual production needs. Of course, users can also set an appropriate number of sets according to their needs, and this is not a limitation. It should be noted that when adding or reducing the number of corresponding second clamp seats 42 and third sensors 44, the number of baffle plates 45 needs to be increased or decreased simultaneously, and the installation position of the baffle plates 45 also needs to be adapted.

[0033] As described above, the material receiving platform 4 of this application enables batch, precise, and safe receiving and directional feeding of qualified materials. The second base 41 provides a stable mounting foundation for each component, ensuring the stability of synchronous movement and the material receiving process. The second clamping seat 42 corresponds to an independent second cylinder 43, which achieves precise lifting and lowering via a connecting plate and a push rod. It can synchronously align with the height of the first clamping seat 251 of the material transfer mechanism 2, preventing material jamming or falling during receiving and improving receiving efficiency and accuracy. The baffle plate 45 is correspondingly set to the second clamping seat 42, and can simultaneously block the gap 241 of the fence 24 during receiving, effectively preventing materials from accidentally detaching due to centrifugal force or pushing impact, improving the stability and safety of receiving. The third sensor 44 independently detects the material arrival status of the corresponding second clamping seat 42, triggering the action of the Z-axis linear module 5, effectively avoiding malfunctions caused by no material running or unstable material placement. Through collaboration with the Z-axis linear module 5, it achieves efficient feeding of qualified materials to subsequent inner and outer shell assembly processes while receiving them, improving production efficiency.

[0034] Continue to refer to Figure 1-3 , Figure 5As shown, the Z-axis linear module 5 includes a support base 51, a linear module body 52 mounted on the support base 51, a second motor 53 connected to the linear module body 52, and a guide rail 54 mounted on the left side of the linear module body 52. ​​The support base 51 is used to support the linear module body 52, the second motor 53, and other core components, fixing the Z-axis linear module 5 to the equipment frame, offsetting vibration and stress during operation, ensuring the overall installation stability of the module, and preventing the movement accuracy of the unloading and receiving platform 4 from being affected by shaking during movement. In this case, the specific structure of the linear module body 52 adopts a synchronous belt type linear module. The synchronous belt type linear module includes a belt, linear guide rail, metal profile base and housing, coupling, motor, etc. Therefore, other specific structures of the linear module body not mentioned in this case can be implemented with reference to the synchronous belt type linear module in the prior art. In specific implementation, the second motor 53 is a servo motor to provide power to the linear module body 52. The linear module body 52 converts the rotational motion of the second motor 53 into the linear motion of the slide block 55 via a synchronous belt drive, driving the unloading and receiving platform 4 to move back and forth. Synchronous belt drive offers advantages such as high speed, low noise, long stroke, and reliable operation. The unloading and receiving platform 4 is slidably connected to the guide rail 54 on its right side, and its upper end is slidably connected to the top of the linear module body 52 via the slide block 55. The guide rail 54 provides additional guiding support for the unloading and receiving platform 4, while the slide block 55 transmits power from the linear module body 52, ensuring that the unloading and receiving platform 4 slides smoothly along a preset trajectory. The dual-guide structure of the guide rail 54 and the slide block 55 improves the smoothness of movement, preventing the unloading and receiving platform 4 from tilting or jamming due to multiple material loads, thus ensuring movement accuracy. A photoelectric switch 56 is also installed on the main body 52 of the linear module. The photoelectric switch 56 detects the movement position of the unloading and receiving platform 4 and feeds back the corresponding signal to control the start and stop of the second motor 53. This achieves precise positioning and overtravel protection for the unloading and receiving platform 4, resulting in higher positioning accuracy and avoiding positioning deviations. No manual monitoring is required, preventing excessive movement that could lead to equipment collisions. It also ensures that the unloading and receiving platform 4 accurately reaches the preset position each time it receives or feeds material, meeting the gripping requirements of the robotic arm in subsequent assembly processes. The Z-axis linear module 5 provided in this case significantly improves the docking efficiency with subsequent inner and outer shell assembly processes, has low operating costs, and is suitable for the high-frequency operation requirements of large-scale production.

[0035] Reference Figures 1-4As shown, the NG unloading station 6 in this case includes a unloading guide 61 connected to the lower end of the material transfer mechanism 2 and a fourth sensor 62 installed on the unloading guide 61. The fourth sensor 62 is used to sense and detect whether NG material is present and whether it is accurately NG-edged from the material transfer mechanism 2, preventing NG material from being accidentally transferred to the next receiving and loading mechanism 1, thus avoiding conflicts with the next round of loading. In specific implementation, the unloading guide 61 adopts an inclined trough structure, which can guide the NG material to slide naturally under gravity. A waste bin can be placed at the lower end of the unloading guide 61 to collect the NG material. The unloading guide 61 does not require an additional drive mechanism, has a simple structure, and ensures smooth conveying, preventing NG material from scattering or accumulating, and ensuring a clean production environment. The fourth sensor 62 is installed at the entrance of the feeding guide 61 to sense and confirm that the material has entered the feeding guide 61. This effectively prevents NG material from continuing to transfer with the turntable 23 due to incomplete material pushing, avoids unqualified material from being mixed into subsequent processes, and prevents material jamming alarms. This greatly improves the reliability and accuracy of product screening.

[0036] Reference Figures 1-4As shown, the loading / unloading pushing mechanism 7 of this invention includes a third base 71, a third cylinder 72 mounted on the third base 71, a pull rod 73 connected to the third cylinder 72 and extending to the left, and a first pushing plate 74 connected to the right side of the third cylinder 72. The pull rod 73 and the first pushing plate 74 can move synchronously with the movement of the third cylinder 72. It should be noted that, in specific implementation, there is a round hole in the middle of the turntable 23, and the third base 71 passes downward through the turntable 23 and is fixedly connected to the first base 21. There is a gap between its bottom and the turntable 24, and it does not rotate with the rotation of the turntable 23. In specific implementation, the pull rod 73 is used to pull the material lifted by the automatic receiving and loading mechanism 1 into the material transfer mechanism 2, and the first pushing plate 74 is used to push the qualified material from the material transfer mechanism 2 into the unloading receiving platform 4. The synchronous operation of loading and unloading is achieved through the third cylinder 72, saving parts, reducing installation space, thereby reducing the size of the equipment, saving the manufacturing cost of the equipment, and improving efficiency. The material pulling rod 73 includes a straight plate 731 and a pull plate 732 vertically connected to the left end of the straight plate 731. The pull plate 732 extends and hangs above the material receiving and feeding mechanism 1. In specific implementation, the pull plate is a smooth plate. When the third cylinder 72 extends, the pull plate 732 moves to the left with the straight plate 731, pulling the material lifted on the receiving platform 11 into the first clamp seat 251 of the material transfer mechanism 2. The first push plate 74 is set facing the unloading receiving platform 4. The first push plate 74 includes a first push block 741 and a first pressure plate 742. Specifically, when the third cylinder 72 extends, the first pressure plate 742 first presses down on the material to prevent deviation, and simultaneously the first push block 741 pushes the material from the clamp into the second clamp seat 42 of the unloading receiving platform 4, ensuring stable and accurate unloading and avoiding material overturning or jamming during pushing. This design of simultaneous loading and unloading greatly improves the working efficiency of the entire device. Compared with the traditional mechanism that performs loading and unloading operations separately, it reduces intermediate waiting time and allows materials to flow more quickly between different processes. Moreover, by using a third cylinder 72 to achieve simultaneous loading and unloading, the number of parts used is reduced, the manufacturing cost of the equipment is lowered, and the potential failure points caused by the coordinated operation of multiple power components are also reduced, thus improving the overall stability and reliability of the device.

[0037] Continue to refer to Figures 1-4As shown, the NG pushing mechanism 8 of this case includes a fourth base 81 mounted on the upper end of the loading / unloading pushing mechanism 7, a fourth cylinder 82 mounted on the fourth base 81, and a second pushing plate 83 connected to the rear end of the fourth cylinder 82 and positioned towards the NG unloading station 6. The NG pushing mechanism 8 is stacked on top of the loading / unloading pushing mechanism 7, simplifying the installation structure, reducing assembly difficulty, and minimizing installation space, thereby reducing the equipment size. When the fourth cylinder 82 receives a signal, it drives the second pushing plate 83 to extend and retract towards the NG unloading station 6, realizing the pushing and diversion of non-conforming materials. The second pushing plate 83 includes a second pushing block 831 and a second pressure plate 832. The structure and function of the second pushing plate 83 are the same as those of the first pushing plate 74; please refer to the description of the first pushing plate 74 in this case.

[0038] It should be noted that the second clamping seat 42 in this case has the same structure as the first clamping seat 251, and both are adapted to the inner shell structure to facilitate stable engagement of the inner shell and ensure stability during the inner shell's transport process. The cylinders mentioned in this case are preferably slide cylinders, but are not limited to this.

[0039] Finally, the working principle of this case is described in the full text: Materials are manually placed into the feeding hopper. After the equipment is started, the feeding hopper 101 of the automatic feeder 100 replenishes the material to the hopper 104 of the vibratory feeder 102 through the feeding guide 1011. The first sensor 108 monitors the material quantity in the hopper in real time to achieve on-demand replenishment and detect the material transportation status. The vibratory feeder body 103 vibrates, causing the material to rise in a sorted manner along the spiral track 105. The material is then conveyed to the receiving platform 11 of the receiving and feeding mechanism 1 via the linear guide 106 and the linear feeder 107. The baffle 14 of the receiving platform 11 and the receiving guide 15 constrain the material trajectory. After the second sensor 12 detects that the material has arrived, it triggers the first cylinder 13 to lift the receiving platform 11, aligning it with the empty material clamp 25 on the turntable 23 of the material transfer mechanism 2. Simultaneously, the first motor 22 of the material transfer mechanism 2 drives the turntable 23 to rotate intermittently. When it reaches the receiving position, the third cylinder 72 of the loading / unloading pushing mechanism 7 extends, and the pull plate 732 of the left pull rod 73 pulls the material from the receiving platform 11 into the first clamp seat 251. The first pressure plate 742 of the right first push plate 74 cooperates with the first push block 741 to push the turntable 23... Qualified materials in the first fixture seat 251 of the unloading station are pushed into the unloading receiving platform 4. When the material rotates with the turntable 23 to the inspection station, the industrial camera 33 of the vision inspection mechanism 3 captures an image of the material with the assistance of the vision light source 35 and outputs a qualified / NG signal. If it is qualified material, the turntable 23 rotates to the unloading station, the Z-axis linear module 5 drives the unloading receiving platform 4 to move forward, the baffle plate 45 blocks the gap 241 of the fence 24, the second cylinder 43 lifts the second fixture seat 42 to align with the first fixture seat 251, and the third sensor 44 detects the material after it is pushed in. When the material arrives, the Z-axis linear module 5 is triggered to move the unloading and receiving platform 4 backward to the next process for material supply. If it is NG material, the turntable continues to rotate to the NG unloading station, triggering the extension of the fourth cylinder 82 of the NG pushing mechanism 8. The second pushing plate 83 pushes the material into the unloading guide 61 of the NG unloading station 6. After the fourth sensor 62 confirms that the material has entered the unloading guide 61, the turntable 23 continues to rotate to enter the next cycle. The entire process realizes the fully automated closed-loop operation of material from automatic feeding, accurate receiving, detection and judgment to qualified feeding and NG diversion.

[0040] This project achieves high efficiency and accuracy in the transport of the blood glucose monitor's inner shell through a fully automated design that includes automatic feeding, precise receiving, cyclic transfer, high-definition visual inspection, synchronous loading and unloading, directional conveying of qualified materials, and automatic diversion of NG materials. Its compact structure and rational layout reduce equipment size and manufacturing costs, and minimize manual intervention and potential failure points through single-cylinder synchronous loading and unloading and stacked installation. Visual inspection replaces manual inspection, improving inspection accuracy and product consistency. Smooth linkage between various mechanisms significantly shortens material flow time, adapts to the needs of large-scale production, and effectively ensures the efficiency of subsequent inner and outer shell assembly processes and product quality.

[0041] As stated above, this case protects an internal shell detection and transfer device, and all technical solutions that are the same as or similar to this case should be considered to fall within the protection scope of this case.
