Description

Technical Field

[0001] This invention relates to the field of medical device manufacturing technology, and in particular to an insulin pen manufacturing system. Background Technology

[0002] A pen-type insulin injector is a product that combines the injectable medication and the syringe into one unit. It typically consists of a pen cap, pen barrel, dosage unit knob, injection button, medication cartridge, and injection needle. Compared to traditional glass syringes, it eliminates the cumbersome process of drawing insulin. Because of its accurate dosage setting, simpler, more flexible, and discreet injection operation, it is suitable for home use and convenient portability. The injection needle is thinner and shorter, causing very little pain during injection, and it avoids the risk of accidentally breaking the syringe when using a glass syringe. Therefore, it is widely used in the field of insulin therapy for diabetic patients.

[0003] However, in the current technology, the existing assembly method for insulin pens is manual assembly, which is inefficient and prone to damage to parts or missing parts, resulting in a high defect rate after assembly. Summary of the Invention

[0004] The main objective of this invention is to propose an insulin pen manufacturing system designed to improve production efficiency.

[0005] To achieve the above objectives, the present invention proposes an insulin pen manufacturing system, comprising:

[0006] A conveyor line includes a conveyor belt and multiple hoppers, the conveyor belt being capable of conveying the hoppers, the hoppers being used to hold assemblies or finished products of insulin injection pens;

[0007] Multiple assembly devices are arranged in a preset order along the extension direction of the conveyor belt, and these multiple assembly devices are capable of assembling the insulin pen in a preset order; and

[0008] A finished product testing device is located downstream of the plurality of assembly devices. The finished product testing device includes an operating platform, a first fixing mechanism, a propulsion accuracy testing mechanism, and a torque testing mechanism disposed on the operating platform. The propulsion accuracy testing mechanism and the torque testing mechanism are disposed on opposite sides of the first fixing mechanism. The first fixing mechanism is used to fix the assembled insulin pen. The propulsion accuracy testing mechanism is used to test the propulsion accuracy of the screw in the insulin pen. The torque testing mechanism is used to detect the operating torque of the insulin pen.

[0009] In one embodiment, the first fixing mechanism includes a fixing seat and a pressing structure. The fixing seat is provided with a first limiting groove for placing the insulin pen, and the pressing structure presses the insulin pen into the first limiting groove.

[0010] In one embodiment, the pressing structure includes a first mounting base mounted on the operating platform and a first mounting frame slidably mounted on the first mounting base. A pressing block is elastically mounted on the first mounting frame, and the pressing block is provided with a second limiting groove. The first mounting frame drives the pressing block to move toward the first limiting groove so that the insulin pen is inserted into the second limiting groove, so that the first limiting groove and the second limiting groove together press the insulin pen.

[0011] The fixing seat includes a fixed base and two protrusions spaced apart. The first limiting groove is provided on the two protrusions, and the two protrusions are misaligned with the pressing block.

[0012] In one embodiment, the torque testing mechanism includes a camera module, a display module, a clamping structure, and a torque force detection element disposed on the clamping structure. The clamping structure can clamp the injection knob of the insulin pen and drive the injection knob to rotate spirally a preset distance. The camera module can record the rotation process of the clamping structure, and the display module is used to display the image captured by the camera module. The torque force detection element can detect and record the torque force of the clamping structure during rotation, and the torque force detection element is electrically connected to the display module to display the change in torque force of the clamping structure during rotation.

[0013] In one embodiment, the torque testing mechanism further includes a second mounting base slidably mounted on the operating platform, a second mounting frame slidably mounted on the second mounting base, and a pushing mechanism. The pushing mechanism and the clamping structure are both disposed on the second mounting frame. The sliding directions of the second mounting base and the second mounting frame are set at an angle, and the second mounting base drives the second mounting frame to slide so that the pushing mechanism is opposite to the insulin pen. The second mounting frame drives the pushing mechanism to move in a closer direction so that the pushing mechanism pushes the injection button of the insulin pen to move a preset distance.

[0014] In one embodiment, the propulsion accuracy testing mechanism includes a third mounting base installed on the testing platform and a third mounting frame slidably installed on the third mounting base. The third mounting frame is slidably mounted with an abutment member, and the abutment member is connected to a displacement detection member and a counterweight member. The abutment member is used to abut against the injection screw of the insulin pen. During the process of the pushing mechanism pushing the injection button of the insulin pen to move, the injection screw pushes the abutment member to move against the resistance of the counterweight member. The displacement detection member can detect the moving distance of the abutment member.

[0015] In one embodiment, the plurality of assembly devices include a pen cap assembly device, which includes a pen body fixture and a pen cap mounting structure. The pen body fixture includes a fixing groove and a spring positioning assembly. The pen body of the insulin injection pen is fixed in the fixing groove. The spring positioning assembly clamps a spring member fixed to the tail of the pen body. The pen cap mounting structure further includes a pen cap retrieving member and a guide member disposed on one side of the pen cap retrieving member. The pen cap retrieving member can attract the pen cap and move it toward the pen body fixture to fix it to the spring member to install the pen cap. The guide member slides against one side of the pen body fixture.

[0016] In one embodiment, the insulin pen manufacturing system further includes a pen cap testing device, which includes a second fixing structure and a pressing structure. The second fixing structure can fix the insulin pen, and the pressing structure can press the pen cap a preset number of times.

[0017] In one embodiment, the assembly device further includes a jig and a pressing structure. The insulin pen includes a first assembly part and a second assembly part. The jig is provided with a third limiting groove adapted to the first assembly part. The pressing structure can assemble and press the second assembly part onto the first assembly part.

[0018] In one embodiment, the insulin pen production system further includes a component inspection station located upstream of the plurality of assembly devices. The component inspection station is equipped with an inspection fixture, which has an inspection slot, allowing the insulin pen to be inserted into the inspection slot for inspection.

[0019] The technical solution of this invention involves setting up a conveyor line, which includes a conveyor belt and multiple material boxes. The conveyor belt transports the material boxes, which are used to hold assembled components or finished products of insulin injection pens. This allows the material boxes to move between multiple assembly devices and testing devices, facilitating easy access by manual labor or robotic arms and improving system automation. Multiple assembly devices are arranged in a preset order along the extension direction of the conveyor belt, assembling the insulin injection pens in this order. This layout ensures that the assembly process of the insulin injection pen proceeds in an orderly manner. Each assembly device has a specific function and task, assembling different components of the injection pen together. For example, the pen cap assembly device is responsible for accurately installing the pen cap onto the pen body, and the screw assembly device is used to assemble the screw. The various assembly devices cooperate and work together, greatly improving production efficiency and assembly quality. The finished product testing device is located downstream of the multiple assembly units. This device includes an operating platform, a first fixing mechanism, a propulsion accuracy testing mechanism, and a torque testing mechanism, all mounted on the operating platform. The propulsion accuracy testing mechanism and the torque testing mechanism are located on opposite sides of the first fixing mechanism. The first fixing mechanism is used to fix the assembled insulin pen, the propulsion accuracy testing mechanism is used to test the propulsion accuracy of the screw in the insulin pen, and the torque testing mechanism is used to test the operating torque of the insulin pen. Only insulin pens that pass the rigorous testing by the finished product testing device can proceed to the next stage of packaging and sales, ensuring that every pen leaving the factory meets finished product standards. Furthermore, this method of directly integrating the finished product testing process into the entire production system makes the production process more compact and efficient, reduces intermediate handling and storage, and lowers production costs and quality risks.

[0043] This invention proposes an insulin pen manufacturing system.

[0044] Please see Figures 1 to 8 In one embodiment of the present invention, the insulin pen production system includes:

[0045] The conveyor line includes a conveyor belt 101 and a plurality of material boxes 102, the conveyor belt 101 being able to convey the material boxes 102, the material boxes 102 being used to hold assemblies or finished products of insulin pen 200.

[0046] Multiple assembly devices 1 are arranged in a preset order along the extension direction of the conveyor belt 101, and the multiple assembly devices 1 are capable of assembling the insulin pen 200 in a preset order; and

[0047] The finished product testing device 2 is located downstream of the plurality of assembly devices 1. The finished product testing device 2 includes an operating platform 21, a first fixing mechanism 22, a propulsion accuracy testing mechanism 23, and a torque testing mechanism 24 disposed on the operating platform 21. The propulsion accuracy testing mechanism 23 and the torque testing mechanism 24 are respectively disposed on opposite sides of the first fixing mechanism 22. The first fixing mechanism 22 is used to fix the assembled insulin pen 200. The propulsion accuracy testing mechanism 23 is used to test the propulsion accuracy of the screw in the insulin pen 200. The torque testing mechanism 24 is used to detect the operating torque of the insulin pen 200.

[0048] Specifically, the conveyor line, as a fundamental component of the insulin pen production system, plays a crucial role in material transportation. The conveyor belt 101 operates at a stable and uniform speed, ensuring that the cartridges 102 are accurately transported to each assembly unit 1 and testing station. This allows the cartridges 102 to move between multiple assembly units 1 and testing stations, facilitating easy access by manual labor or robotic arms and enhancing system automation. The cartridge 102 is ingeniously designed, providing excellent protection and positioning for the assembled or finished insulin pen 200 components, preventing collisions or displacement during transport.

[0049] Multiple assembly devices 1 are arranged in a predetermined order along the extension direction of the conveyor belt 101. This layout allows the assembly process of the insulin pen 200 to proceed smoothly. Each assembly device 1 has its specific function and task, thereby assembling different components of the pen together. For example, the pen cap assembly device 11 is responsible for accurately installing the pen cap onto the pen body, and the screw assembly device 1 is used to assemble the screw. The various assembly devices 1 cooperate and work together, greatly improving production efficiency and assembly quality. Generally, the insulin pen 200 often includes many assembly components, therefore there are multiple assembly devices 1, and each assembly device 1 can assemble at least one component. Moreover, the assembly device 1 can realize the automatic assembly of the insulin pen 200. Only an operator or a robotic arm needs to place the component to be assembled in the preset position, thereby improving the automation level of the insulin pen 200, thus improving the automation level of the insulin pen production system, and improving the production accuracy and efficiency of the insulin pen 200.

[0050] The finished product inspection device 2 is located downstream of the multiple assembly devices 1, serving as the final line of defense to ensure the quality of the insulin pen 200. The operating platform 21 provides a stable working environment for each inspection mechanism. The first fixing mechanism 22 securely holds the assembled insulin pen 200, ensuring accurate testing by the propulsion accuracy testing mechanism 23 and the torque testing mechanism 24. The propulsion accuracy testing mechanism 23 accurately detects the propulsion accuracy of the screw in the insulin pen 200 to determine if it meets design requirements; the torque testing mechanism 24 detects the operating torque of the insulin pen 200 to ensure smooth and stable operation. Only insulin pens 200 that pass the rigorous inspection of the finished product inspection device 2 can proceed to the next stage of packaging and sales, ensuring that every pen leaving the factory meets finished product standards. Furthermore, this method of directly integrating the finished product inspection process into the entire production system makes the production process more compact and efficient, reducing intermediate handling and storage, and lowering production costs and quality risks. Meanwhile, rigorous testing of each insulin pen 200 allows for the timely detection and elimination of potential quality issues, improving product reliability and safety and enhancing user trust. Throughout the insulin pen production system, all components work closely together. Conveyor lines continuously transport assemblies and finished products to their designated locations, multiple assembly units 1 complete assembly tasks sequentially according to a preset order, and the finished product testing unit 2 rigorously inspects the assembled insulin pens 200. This highly automated and intelligent production method not only improves production efficiency and reduces labor costs but also significantly enhances the production quality and stability of the insulin pens 200, providing diabetic patients with more reliable medical products.

[0051] In actual production, to further improve production efficiency and quality, the insulin pen production system can be optimized and improved. For example, advanced sensors and control systems can be introduced to achieve real-time monitoring and automatic adjustment of the conveyor line, assembly unit 1, and testing device, ensuring stable operation of each link. Furthermore, intelligent data analysis and management systems can be adopted to collect, analyze, and process data during the production process, enabling timely identification of problems and optimization points, and providing strong support for production decisions.

[0052] Furthermore, to improve the flexibility and adaptability of the insulin pen production system, a modular design for the assembly unit 1 can be considered. This way, when different models or specifications of insulin pens 200 need to be produced, only the corresponding assembly modules need to be replaced, allowing for rapid adjustment of the production system configuration to meet diverse production needs. Simultaneously, the modular design facilitates the maintenance and upgrades of the assembly unit 1, reducing equipment maintenance costs and downtime.

[0053] See Figure 5 and Figure 7 In an embodiment of the present invention, the first fixing mechanism 22 includes a fixing base 221 and a pressing structure 222. The fixing base 221 is provided with a first limiting groove 2211 for placing the insulin pen 200, and the pressing structure 222 presses the insulin pen 200 into the first limiting groove 2211. Specifically, the fixing base 221 provides a stable foundation for placing the insulin pen 200, and the design of the first limiting groove 2211 can accurately position the insulin pen 200, preventing it from shifting during the testing process and ensuring the accuracy of the test. The pressing structure 222 further enhances the stability of the insulin pen 200 on the fixing base 221. By firmly pressing it into the first limiting groove 2211, it prevents the insulin pen 200 from shaking or shifting due to external forces when the precision testing mechanism 23 and the torque testing mechanism 24 are working, thereby affecting the reliability of the test results.

[0054] In practical applications, the fixing base 221 can be made of high-strength, wear-resistant materials to ensure that it will not deform or be damaged during long-term use. The clamping structure 222 can be pneumatic or electric to achieve fast and stable clamping operation, improving detection efficiency. Simultaneously, buffer material can be placed within the first limiting groove 2211 to further reduce friction and collision between the insulin pen 200 and the fixing base 221, protecting the pen's appearance and performance.

[0055] Furthermore, the pressing structure 222 includes a first mounting base 2221 mounted on the operating platform 21 and a first mounting frame 2222 slidably mounted on the first mounting base 2221. The pressing block 2223 is elastically mounted on the first mounting frame 2222, and the pressing block 2223 is provided with a second limiting groove 2224. The first mounting frame 2222 drives the pressing block 2223 to move towards the first limiting groove 2211, so that the insulin pen 200 is inserted into the second limiting groove 2224, so that the first limiting groove 2211 and the second limiting groove 2224 jointly press the insulin pen 200. The fixing base 221 includes a fixing base and two protrusions 2212 spaced apart. The first limiting groove 2211 is provided on the two protrusions 2212, and the two protrusions 2212 are offset from the pressing block 2223. Specifically, the first mounting base 2221 provides support and guidance for the sliding of the first mounting bracket 2222, enabling the first mounting bracket 2222 to move accurately along a preset trajectory, thereby causing the pressing block 2223 to move closer to or away from the first limiting groove 2211. The pressing block 2223 is elastically mounted on the first mounting bracket 2222. This design allows the pressing block 2223 to undergo a certain elastic deformation when in contact with the insulin pen 200, thus ensuring the clamping force while avoiding excessive compression and damage to the pen. The second limiting groove 2224 further enhances the positioning and fixing effect of the insulin pen 200, cooperating with the first limiting groove 2211 to constrain the pen from different directions, ensuring its stability during the testing process.

[0056] The fixing base of the fixing seat 221 provides a stable foundation for the overall structure. Two protrusions 2212, spaced apart, not only form the first limiting groove 2211 but are also offset from the pressing block 2223. This offset arrangement avoids interference during pressing, allowing the pressing structure 222 to smoothly press the insulin pen 200. Simultaneously, the design of the two protrusions 2212 increases the contact area with the pen, improving the reliability of the fixation.

[0057] In the actual finished product testing operation, the operator first places the assembled insulin pen 200 into the first limiting groove 2211 of the fixing base 221. At this time, the pen is initially positioned by the action of the first limiting groove 2211. Then, by controlling the sliding of the first mounting bracket 2222, it drives the pressing block 2223 to move towards the first limiting groove 2211. When the pressing block 2223 approaches the pen, due to its elastic mounting characteristics, it gradually contacts the pen and applies a certain pressure, eventually causing the pen to be engaged in the second limiting groove 2224. At this time, the first limiting groove 2211 and the second limiting groove 2224 work together to firmly press the insulin pen 200 onto the fixing base 221.

[0058] The first mounting base 2221 can also be slidably mounted on the operating platform 21, allowing operators to easily adjust its position to meet the testing requirements of different models or specifications of insulin pens 200. This slidable design increases the flexibility and versatility of the first fixing mechanism 22, enabling the insulin pen production system to better handle diverse production and testing tasks. When adjusting the position of the first mounting base 2221, smooth sliding can be achieved via guide rails and sliders on the operating platform 21. The first mounting bracket 2222 can also be smoothly slidably mounted via guide rails and sliders. The pressing block 2223 can be slidably mounted on the first mounting bracket 2222 via a connecting post, and an elastic element is provided between the connecting post and / or the pressing block 2223 and the first mounting bracket 2222 to achieve elastic mounting of the pressing block 2223.

[0059] To ensure the convenience and accuracy of the operating torque of the insulin pen 200, in one embodiment, see [reference needed]. Figure 5 and Figure 6 The torque testing mechanism 24 includes a camera module 241, a display module 242, a clamping structure 243, and a torque force detection element disposed on the clamping structure 243. The clamping structure 243 can clamp the injection knob 201 of the insulin pen 200 and drive the injection knob 201 to rotate spirally a preset distance. The camera module 241 can record the rotation process of the clamping structure 243, and the display module 242 is used to display the image captured by the camera module 241. The torque force detection element can detect and record the torque force of the clamping structure 243 during the rotation process, and the torque force detection element is electrically connected to the display module 242 to display the change in torque force of the clamping structure 243 during the rotation process. Specifically, the camera module 241 provides an intuitive record of the torque testing process, and it can clearly capture the entire process of the clamping structure 243 driving the injection knob 201 to rotate spirally a preset distance. Operators can view the captured footage at any time through the display module 242, closely observe the rotation process, and determine if there are any abnormalities, such as jamming or uneven rotation. The display module 242 not only displays the camera footage but is also electrically connected to the torque force detection element, displaying the real-time torque force changes of the clamping structure 243 during rotation. This allows operators to promptly grasp the dynamic situation of the torque force and intuitively understand whether the operating torque of the insulin pen 200 is stable within a reasonable range.

[0060] The clamping structure 243 is a key component in torque testing. It precisely clamps onto the injection knob 201 of the insulin pen 200, ensuring the stability and reliability of the testing mechanism during the testing process and preventing loosening or slippage when rotating the injection knob 201. The operation of rotating the injection knob 201 a preset distance simulates the user's actions when actually using the insulin pen 200, thus accurately detecting the operating torque of the pen. The clamping structure 243 includes two clamping members that can move closer or further apart, and the clamping members are equipped with buffers to ensure clamping force while reducing the possibility of wear on the insulin pen 200.

[0061] The torque force detection device can detect and record the torque force data of the clamping structure 243 during rotation in real time and accurately. By analyzing the changes in torque force, the smoothness and stability of the injection pen operation can be evaluated. If the torque force fluctuates too much or exceeds the specified range, it indicates that there may be a quality problem with the injection pen, requiring further inspection and adjustment.

[0062] In actual testing, after the operator fixes the insulin pen 200 to the first fixing mechanism 22, the torque testing mechanism 24 is activated. The clamping structure 243 quickly and accurately clamps the injection knob 201, and then drives it to rotate a preset distance according to a preset program. During this process, the camera module 241 continuously records the rotation, and the torque force detection device synchronously detects and records the changes in torque force. These data and images are transmitted to the display module 242 in real time, allowing the operator to evaluate and judge based on the displayed information.

[0063] Furthermore, the torque testing mechanism 24 also includes a second mounting base 244 slidably mounted on the operating platform 21, a second mounting bracket 245 slidably mounted on the second mounting base 244, and a pushing mechanism 246. The pushing mechanism 246 and the clamping structure 243 are both located on the second mounting bracket 245. The sliding directions of the second mounting base 244 and the second mounting bracket 245 are set at an angle, and the second mounting base 244 drives the second mounting bracket 245 to slide, so that the pushing mechanism 246 is opposite to the insulin pen 200. The second mounting bracket 245 drives the pushing mechanism 246 to move closer, so that the pushing mechanism 246 pushes the injection button 202 of the insulin pen 200 to move a preset distance. Specifically, the design of the second mounting base 244 and the second mounting bracket 245 allows the pushing mechanism 246 to flexibly adjust its position and direction of movement. The second mounting bracket 245 can move relative to the second mounting base 244, thereby enabling the second mounting bracket 245 to drive the pushing mechanism 246 to push the injection button 202. The sliding directions of the second mounting base 244 and the second mounting bracket 245 are set at an angle, and the second mounting base 244 can drive the second mounting bracket 245 to slide as a whole, thereby switching between the clamping mechanism and the pushing mechanism 246. This facilitates switching between torque testing and screw advance accuracy detection, improving testing efficiency and the overall practicality of the system. In actual operation, when torque testing is required, the second mounting base 244 drives the second mounting bracket 245 to slide to a suitable position, aligning the clamping structure 243 with the injection knob 201 of the insulin pen 200 for torque testing. When screw advance accuracy detection is required, the second mounting base 244 again drives the second mounting bracket 245 to slide, switching to a position where the pushing mechanism 246 is opposite to the insulin pen 200. The second mounting bracket 245 drives the pushing mechanism 246 to approach and push the injection button 202 to move a preset distance to complete the screw advance accuracy detection.

[0064] The function of the actuating mechanism 246 is to simulate the action of a user pressing the injection button 202 of the insulin pen 200. When the second mounting bracket 245 drives the actuating mechanism 246 to move closer to the insulin pen 200, the actuating mechanism 246 pushes the injection button 202 a preset distance. This preset distance is set according to the design requirements of the insulin pen 200 and actual usage conditions. By simulating a real injection operation, the performance of the pen in actual use can be tested. During the process of the actuating mechanism 246 pushing the injection button 202, other testing methods can be combined to further evaluate the performance of the insulin pen 200. For example, the pressing force of the injection button 202, the smoothness of pushing, and whether it can be accurately pushed to the preset position can be tested. These test data can be combined with the torque force data detected by the torque testing mechanism 24 to comprehensively evaluate the quality and performance of the insulin pen 200.

[0065] For further details, please refer to [link / reference]. Figure 5 , Figure 6 and Figure 8 The propulsion accuracy testing mechanism 23 includes a third mounting base 231 mounted on the testing platform and a third mounting frame 232 slidably mounted on the third mounting base 231. The third mounting frame 232 has a slidingly mounted abutment 233, which is connected to a displacement detection element 234 and a counterweight 235. The abutment 233 abuts against the injection screw of the insulin pen 200. During the process of the pushing mechanism 246 pushing the injection button 202 of the insulin pen 200 to move, the injection screw pushes the abutment 233 to overcome the resistance of the counterweight 235. The displacement detection element 234 can detect the movement distance of the abutment 233. Specifically,

[0066] The third mounting base 231 provides stable support and guidance for the sliding of the third mounting bracket 232, enabling the third mounting bracket 232 to move smoothly along a preset path. The abutment 233 is slidably mounted on the third mounting bracket 232, a design that ensures that the abutment 233 can flexibly contact and separate from the injection screw. When the pushing mechanism 246 pushes the injection button 202, and the injection screw moves forward, it pushes the abutment 233 to overcome the resistance of the counterweight 235 and move.

[0067] The placement of the counterweight 235 is crucial, as it simulates the resistance encountered during insulin injection, making the testing process more closely resemble actual usage. The displacement sensor 234 accurately measures the movement distance of the contact member 233, reflecting the advancement accuracy of the injection screw. If the advancement accuracy of the injection screw is inaccurate, the movement distance of the contact member 233 will deviate from the preset value.

[0068] In actual testing, after the operator secures the insulin pen 200, they activate the pushing mechanism 246 and push the injection button 202. The injection screw then moves the abutment member 233, and the displacement detection member 234 records the movement data of the abutment member 233 in real time. By analyzing this data, it can be determined whether the advancement accuracy of the insulin pen 200 meets the standard. If the advancement accuracy does not meet the requirements, it indicates that the pen may have a manufacturing defect and needs adjustment or further inspection.

[0069] To improve the accuracy and stability of the propulsion accuracy testing mechanism 23, the third mounting base 231 and the third mounting bracket 232 can be installed using a high-precision screw drive to ensure the precise movement trajectory of the contact member 233. Similarly, the second mounting bracket 245 and the second mounting base 244 can also be installed using a high-precision screw drive to ensure transmission accuracy. Meanwhile, the displacement detection member 234 can be equipped with a high-precision sensor to ensure the accuracy of the measurement data. Furthermore, the weight of the counterweight 235 can be precisely calibrated to accurately simulate resistance under different usage scenarios, further improving the reliability of the test. Through these optimization measures, the propulsion accuracy testing mechanism 23 can more effectively test the performance of the insulin pen 200, providing a strong guarantee for the production of high-quality medical products.

[0070] See Figure 9 and Figure 10 In an embodiment of the present invention, the plurality of assembly devices 1 include a pen cap assembly device 11, which includes a pen body fixture 111 and a pen cap mounting structure 112. The pen body fixture 111 includes a fixing groove 1111 and a spring positioning assembly 1112. The pen body of the insulin injection pen 200 is fixed in the fixing groove 1111. The spring positioning assembly 1112 clamps and fixes a spring member fixed to the tail of the pen body. The pen cap mounting structure 112 also includes a pen cap taking member 1121 and a guide member provided on one side of the pen cap taking member 1121. The pen cap taking member 1121 can adsorb the pen cap and move towards the pen body fixture 111 to fix it to the spring member to install the pen cap. The guide member slides against one side of the pen body fixture 111.

[0071] Specifically, the fixing groove 1111 of the pen body fixture 111 provides a stable placement space for the pen body of the insulin pen 200, ensuring that the pen body will not shake or shift during assembly. The spring positioning component 1112 precisely clamps and fixes the spring component at the tail of the pen body, ensuring the accuracy of the spring component's position during assembly and laying a good foundation for the subsequent installation of the pen cap. The pen cap taking component 1121 picks up the pen cap through adsorption, which makes it convenient and quick to grasp the pen cap, improving assembly efficiency. After adsorbing the pen cap, the pen cap taking component 1121 moves towards the pen body fixture 111, accurately fixing the pen cap to the spring component. Then, it continues to move towards the pen body fixture 111, thereby further pressing the pen cap onto the pen body, thus completing the installation of the pen cap. At this time, the guide component slides against one side of the pen body fixture 111, playing an important guiding role. It ensures the accurate trajectory of the pen cap removal component 1121 during movement, allowing the pen cap to accurately align with the pen body and spring component, avoiding assembly failures or quality issues caused by positional deviations. The presence of the guide component also reduces friction during assembly to some extent, making pen cap installation smoother.

[0072] In the actual pen cap assembly operation, the operator first places the body of the insulin pen 200 into the fixing groove 1111 of the pen body fixture 111. The spring positioning component 1112 automatically clamps and fixes the spring component at the tail of the pen body. Then, the pen cap take-up component 1121 adsorbs the pen cap and moves it closer to the pen body fixture 111. Guided by the guide component, the pen cap is further pressed against the pen body. The whole process is efficient and accurate, greatly improving the assembly quality and efficiency of the insulin pen 200. To further improve the performance and stability of the pen cap assembly device 11, the pen cap take-up component 1121 can adopt advanced adsorption technology, such as vacuum adsorption or magnetic adsorption, to ensure that the pen cap will not fall off during the picking and moving process.

[0073] For further details, please refer to [link / reference]. Figure 11 and Figure 12 The insulin pen manufacturing system also includes a pen cap testing device 3. The pen cap testing device 3 includes a second fixing structure 31 and a pressing structure 32. The second fixing structure 31 can fix the insulin pen 200, and the pressing structure 32 can press the pen cap a preset number of times. Specifically, the second fixing structure 31 provides a stable fixing method for the insulin pen 200, ensuring that it will not shake or shift during testing, thereby ensuring the accuracy of the test results. It can take various forms, such as clamps or slots, and can be designed according to the shape and structural characteristics of the insulin pen 200 to achieve a secure fixation.

[0074] The pressing mechanism 32 simulates the action of a user pressing the pen cap during actual use. It can press the pen cap a preset number of times, which is usually determined based on the designed lifespan of the insulin pen 200 and actual usage. During the pressing process, the pressing mechanism 32 can precisely control the pressing force and frequency to ensure the standardization and consistency of the test.

[0075] To ensure the stability and accuracy of the pressing structure 32, it can be installed using high-precision guide rails and sliders, ensuring linear movement during pressing and preventing deviation or wobbling. Simultaneously, the pressing structure 32 can be equipped with a pressure sensor to monitor the pressing pressure in real time and feed the data back to the control system. If the pressure exceeds the preset range, the control system can promptly issue an alarm, prompting the operator to make adjustments.

[0076] In actual testing, the operator first fixes the insulin pen 200 to the second fixing structure 31, then activates the pressing structure 32 to press the pen cap a preset number of times. During the pressing process, the pressure sensor records the pressure data in real time, and the appearance changes of the pen cap after multiple presses can be observed, such as whether deformation or cracks occur. By analyzing these data and appearance changes, it can be determined whether the quality and durability of the pen cap meet the standards. If the pen cap exhibits quality problems during the test, such as failing to reset properly after pressing, or showing obvious deformation or damage, it indicates that the pen cap may have a manufacturing defect, requiring adjustments to the manufacturing process or replacement of the pen cap. Through the detection of the pen cap testing device 3, quality problems of the pen cap can be detected in a timely manner, improving the overall quality and reliability of the insulin pen 200 and ensuring safe use by patients.

[0077] Furthermore, the pen cap testing device 3 can be connected to a data management system to store and analyze data from each test. By statistically analyzing a large amount of test data, trends in pen cap quality can be summarized, providing a basis for improving production processes and optimizing products. Simultaneously, this data can also serve as an important basis for product quality traceability, facilitating tracing and identifying the root cause of quality problems.

[0078] See Figures 13 to 15 In embodiments of the present invention, the assembly device 1 further includes a fixture 12 and a pressing structure 13. The insulin pen 200 includes a first assembly part and a second assembly part. The fixture 12 is provided with a third limiting groove 121 adapted to the first assembly part. The pressing structure 13 can assemble and press the second assembly part onto the first assembly part. Specifically, the third limiting groove 121 of the fixture 12 provides precise positioning and stable support for the first assembly part, ensuring that the first assembly part is in the correct position during the pressing process and will not shift or shake. This ensures the accuracy and consistency of the assembly, so that the assembly quality of each insulin pen 200 can reach a high standard. The pressing structure 13 undertakes the important task of accurately and firmly assembling the second assembly part onto the first assembly part. It applies appropriate pressure to tightly bond the two assembly parts together.

[0079] In this solution, the assembly of different components is achieved by using a groove or fixing structure on the fixture 12 that is compatible with one of the components for stable fixation. Then, the components are brought closer together and further pressed together by the pressing structure 13. The structure of the fixture 12 can be specifically designed according to the shape or structure of the actual components. The pressing structure 13 can directly grip another component to be assembled, or it can be fixed to the component by manual labor or a robotic arm. Pre-installation can be performed manually or by a robotic arm, followed by pressing and fixing by the pressing structure 13. Furthermore, to improve flexibility, the fixture 12 can be slidably mounted on the operating table. This allows the fixture 12 to move flexibly during different assembly processes, facilitating position adjustments to accommodate different pressing operations.

[0080] Taking the assembly of the transmission structure between the screw and the injection pusher as an example, the transmission structure includes a transmission body 203 and a snap ring. The transmission body 203 is snapped and fixed in the third limiting groove 121. The pressing structure 13 correspondingly snaps the snap ring into the transmission body 203 and further presses the snap ring into the transmission body 203 to ensure that the installation is in place.

[0081] In the actual assembly operation, the operator first places the first assembly part into the third limiting groove 121 of the fixture 12. Since the third limiting groove 121 is compatible with the first assembly part, the first assembly part can be naturally and accurately positioned in the groove. Then, the operator activates the pressing structure 13, which applies pressure to the second assembly part according to a preset program and force, slowly pressing it towards the first assembly part. During the pressing process, the pressing structure 13 continuously monitors the magnitude of the pressure and the depth of the pressing to ensure that the two assembly parts can be perfectly joined together.

[0082] To further improve assembly quality and efficiency, the crimping structure 13 can be equipped with a pressure sensor and a displacement sensor. The pressure sensor can monitor pressure changes in real time during the crimping process, ensuring that the pressure remains within a suitable range. Excessive pressure may damage the assembly part; insufficient pressure may result in an insecure assembly. The displacement sensor can accurately measure the crimping depth, ensuring that the second assembly part can be accurately fitted onto the first assembly part, achieving the designed position.

[0083] Meanwhile, the surfaces of the fixture 12 and the pressing structure 13 can be specially treated, such as polishing or applying a wear-resistant coating. This reduces friction, lowers resistance during assembly, and makes the pressing process smoother. Moreover, the wear-resistant coating can also extend the service life of the fixture 12 and the pressing structure 13, reducing the problem of decreased accuracy due to wear.

[0084] Additionally, see Figures 1 to 2The system can be configured with component inspection stations 5 downstream of each assembly process. After the crimping assembly is completed, a preliminary inspection of the assembled insulin pen 200 can be performed. The inspection includes checking the tightness of the connection between the two assembly parts and whether there are scratches or damage on the surface. If any defective products are found, rework or adjustments can be made promptly to ensure the quality of the final product. Through the effective cooperation of the fixture 12 and the crimping structure 13, the assembly process of the insulin pen 200 is more efficient and precise, providing a strong guarantee for producing high-quality insulin pens 200. Alternatively, only components requiring high assembly precision can be inspected. For example, after the screw is initially installed, the torque of the screw can be preliminarily tested to identify and address potential installation problems early. This avoids discovering problems in subsequent processes, reducing unnecessary waste and cost increases. For products that pass the preliminary inspection, subsequent assembly processes can continue, such as installing the outer shell and adding markings. Multiple component inspection stations 5 can be configured to continuously inspect multiple aspects and parts of the insulin pen 200. In other embodiments, multiple tests can be performed consecutively after multiple assembly processes are completed, and designers can design accordingly based on actual needs.

[0085] See Figure 3 and Figure 16 In an embodiment of the present invention, the insulin pen production system further includes a component inspection station 4, located upstream of multiple assembly devices 1. The component inspection station 4 is equipped with an inspection fixture 41, within which is an inspection groove 42. The insulin pen 200 can be inserted into the inspection groove 42 for inspection. Specifically, the size and shape of the inspection groove 42 are precisely designed based on the shape and structural characteristics of the components of the insulin pen 200, enabling a tight and precise fit with the insulin pen 200. Operators can determine whether the dimensions of a component meet the requirements based on whether it can be smoothly inserted into the inspection groove 42; alternatively, after the component is inserted into the inspection groove 42, its qualification can be determined by accurately measuring parameters such as the length, diameter, position, and spacing of each component.

[0086] By setting up component inspection stations 4 upstream of multiple assembly units 1, problems with the components of the insulin pen 200 can be detected early in the production process, preventing unqualified components from flowing into subsequent assembly processes, thereby improving the efficiency and product quality of the entire production system. Simultaneously, the large amount of inspection data collected by the inspection fixtures 41 can provide important evidence for improving and optimizing the production process, helping to continuously improve the production quality and performance of the insulin pen 200. Furthermore, this solution integrates the pre-production inspection of components, the assembly and inspection of components, and the final finished product inspection onto the same production line, achieving full-process quality control of the insulin pen 200 production process. After inspection at the component inspection station 4, qualified components can directly enter the subsequent assembly unit 1 for assembly, reducing transportation and transfer links and improving production efficiency. At the same time, data from each inspection stage can be correlated and shared, facilitating comprehensive quality monitoring and traceability of the entire production process.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the protection scope of the present invention.
