Description

Technical Field

[0001] This invention relates to an appearance inspection mechanism for insulin injectors, belonging to the field of appearance inspection technology. Background Technology

[0002] Insulin injectors are essential medical devices for daily medication use by diabetic patients, and their appearance quality directly affects medication safety.

[0003] Existing methods for inspecting the appearance of insulin syringes often involve using industrial cameras to take pictures of the syringes at a fixed angle and then using image recognition algorithms to identify defects. However, since the camera positions of existing insulin syringe appearance inspection agencies are usually fixed, a single shot can only cover one side of the syringe and cannot inspect the circumferential outer surface of the syringe body, resulting in low inspection accuracy for insulin syringes.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an appearance inspection mechanism for insulin syringes, which solves the problem that the camera position of existing insulin syringe appearance inspection mechanisms is usually fixed, and a single shot can only cover one side of the syringe, making it impossible to inspect the circumferential outer surface of the syringe body, resulting in low detection accuracy of insulin syringes.

[0006] The technical problem to be solved by the present invention is achieved by the following technical solution: an appearance inspection mechanism for an insulin injector, including a base, a mounting frame fixedly mounted on the base, a fixing plate 1 fixedly mounted on the mounting frame, a first stabilizing groove through the fixing plate 1, a support block slidably connected in the first stabilizing groove, a cylinder 2 fixedly mounted on the mounting frame, the telescopic end of the cylinder 2 fixedly connected to the support block, a fixing plate 2 fixedly connected to the support block, a mounting plate 2 provided on the fixing plate 2, two rotating shafts rotatably connected on the mounting plate, a pulley 2 and a pulley 1 respectively rotatably mounted on the two rotating shafts, a driving assembly provided on the fixing plate 2, the driving assembly being able to drive the pulley 2 and the pulley 1 to rotate; An installation box is fixedly mounted on the base, and a supplementary lighting component is provided on the base; A mounting base is fixedly installed on the mounting plate. Two rotating grooves are provided on the side of the mounting base away from the mounting plate. A rotating groove is provided on the side of the mounting base away from the rotating groove. A rotating shaft is rotatably connected in each of the two rotating grooves. A rotating disk is fixedly connected to one end of the rotating shaft. The other ends of the two rotating shafts are fixedly connected to the two rotating shafts respectively. The rotating disk is slidably connected to the rotating groove. An injection needle assembly is provided on the rotating disk, and a limiting mechanism is provided on the rotating disk to limit the position of the injection needle assembly. The base is equipped with a cleaning component that can clean the injection needle assembly.

[0007] The present invention is further configured such that: the drive assembly includes a motor, the motor is fixedly mounted on a mounting plate, the output shaft of the motor is poweredly connected to a third pulley, a fourth pulley is fixedly connected to the rotating shaft on which the second pulley is mounted, and synchronous belts are rotatably connected between the fourth pulley and the third pulley, and between the second pulley and the first pulley.

[0008] By adopting the above technical solution, the starting motor can drive pulley three to rotate. Because pulley three and the fourth pulley are connected by a synchronous belt, the rotation of pulley three can drive the fourth pulley and pulley two to rotate. The rotation of pulley two synchronously drives pulley one to rotate. The rotation of pulley one and pulley two drives two rotating shafts to rotate. The rotation of the rotating shaft synchronously drives the rotating shaft to rotate. The rotation of the rotating shaft synchronously drives the rotating disc to rotate.

[0009] The present invention is further configured such that: a camera is fixedly installed inside the installation box, and the injection needle assembly includes a first positioning block and a needle body, the first positioning block is fixedly sleeved on the injection needle assembly, and the needle body is disposed inside the injection needle assembly.

[0010] The invention is further configured such that: a cylinder three is fixedly installed on the fixed plate two, a connecting block is fixedly connected to the telescopic end of the cylinder three, a second stabilizing groove is provided through the fixed plate two, the connecting block is slidably connected to the second stabilizing groove, and the connecting block is fixedly connected to the mounting plate.

[0011] The present invention is further configured such that: the supplementary lighting component includes a rotating illumination lamp, the rotating illumination lamp is fixedly installed on the base, a supplementary lighting chamber is fixedly installed on the base, a supplementary lighting lamp is installed in the supplementary lighting chamber, and a through groove is provided through the supplementary lighting chamber.

[0012] By adopting the above technical solution, the starting cylinder three can drive the connecting block to move. The movement of the connecting block synchronously drives the mounting plate to move, and the movement of the mounting plate synchronously drives the fixed seat, rotating shaft, motor, pulley three, pulley two, pulley one, etc. to move synchronously. This allows the position of the two rotating shafts and the rotating disk to be adjusted, so that the rotating disk can drive the injection needle assembly to align with the camera during the movement. The camera takes pictures of the injection needle assembly on the rotating disk through the through slot, thereby performing appearance inspection of the injection needle assembly without manual inspection, saving manpower. When an injection needle assembly is aligned with the camera, the starting motor can drive the rotating disk to rotate. The rotation of the rotating disk synchronously drives the injection needle assembly to rotate, and the camera takes pictures of the rotating injection needle assembly, thereby increasing the shooting range of the injection needle assembly and making the inspection range of the injection needle assembly more comprehensive, improving the inspection quality of the appearance of the insulin syringe. The lights in the supplementary lighting chamber illuminate the needle body and injection needle assembly to provide supplementary lighting, making the camera image clearer, thereby ensuring the stability of the inspection.

[0013] By adopting the above technical solution, when an injection needle assembly is aligned with the camera, the starter motor drives the rotating disk to rotate, and the rotating disk synchronously drives the injection needle assembly to rotate. The camera captures the rotating injection needle assembly, thereby increasing the shooting range of the injection needle assembly and making the detection range of the injection needle assembly more comprehensive. This improves the detection quality of the appearance of the insulin syringe. The lights in the supplementary lighting chamber illuminate the needle body and injection needle assembly to provide supplementary lighting, making the camera capture clearer and ensuring the stability of the detection.

[0014] The present invention is further configured such that: the cleaning component includes a cleaning tank, a cylinder is fixedly installed on the base, the telescopic end of the cylinder is fixedly connected to the cleaning tank, a limiting cylinder is fixedly connected to one side of the cleaning tank, a guide bucket is fixedly connected to the lower side of the limiting cylinder, a sealing ring is fixedly connected to the side of the limiting cylinder away from the cleaning tank, a connecting pipe is fixedly connected to the lower side of the guide bucket, the connecting pipe communicates with the inside of the guide bucket, a filter box is fixedly connected to the end of the connecting pipe away from the guide bucket, and filter cotton is fixedly connected inside the filter box.

[0015] The present invention is further configured such that: the cleaning assembly also includes a pump body one and a pump body two, the pump body one and the pump body two are fixedly installed in the cleaning tank, an air pipe is fixedly installed on the limiting cylinder, the end of the air pipe away from the limiting cylinder is fixedly connected to the upper surface of the cleaning tank, a liquid pipe one is fixedly connected to the limiting cylinder, the end of the liquid pipe one away from the limiting cylinder passes through the cleaning tank and is fixedly connected to the output end of the pump body one, and a liquid pipe two is fixedly connected to the lower side of the filter box, the end of the liquid pipe two away from the filter box passes through the cleaning tank and is fixedly connected to the input end of the pump body two.

[0016] By adopting the above technical solution, when cleaning the needle body, the first cylinder is activated to move the cleaning box. During the movement of the cleaning box, the limiting cylinder is moved so that the side of the limiting cylinder away from the cleaning box is inserted into the rotating groove, causing the sealing ring to abut against the inner wall of the rotating groove away from the cleaning box. During this process, the limiting cylinder is covered inside the injection needle assembly. As the cleaning box continues to move, the sealing ring is squeezed to seal the limiting cylinder. At this time, the first pump body is activated. At this time, the solenoid valve on the second liquid pipe closes to seal the second liquid pipe, the solenoid valve on the first liquid pipe opens, and the solenoid valve on the connecting pipe closes, thus cleaning the contents of the cleaning box. The cleaning solution is delivered to the limiting cylinder through the cleaning tank. At this time, the air in the limiting cylinder is squeezed out through the air tube and sent into the cleaning tank. When an appropriate amount of cleaning solution is injected into the limiting cylinder, the cleaning solution submerges the injection needle assembly and needle body. At this time, the motor is started, which drives the injection needle assembly and needle body to rotate. During the rotation of the injection needle assembly and needle body, the cleaning solution cleans the injection needle assembly and needle body, removing burrs and dirt adhering to the surface of the needle body. This results in higher quality and greater accuracy of the external inspection of the needle body and injection needle assembly, thereby improving the inspection quality of the insulin injector appearance inspection mechanism.

[0017] The present invention is further configured such that: the limiting mechanism includes a limiting groove, the limiting groove is opened on the side of the rotating disk away from the rotating shaft, the inner wall of the limiting groove near the rotating shaft is provided with a slot, one end of the injection needle assembly can be inserted into the slot, a slider is fixedly connected to the outer side of the injection needle assembly, a sliding groove is opened on the inner wall of the slot, and the slider can be inserted into the sliding groove.

[0018] The present invention is further configured such that: the limiting mechanism includes a plurality of insertion holes opened on the outer side of the rotating disk, a limiting rod is slidably connected in the insertion hole, a positioning groove is opened in the insertion hole, a second positioning block is fixedly connected to the limiting rod, the second positioning block is slidably connected in the positioning groove, a positioning spring is fixedly connected to the side of the second positioning block away from the slot, the end of the positioning spring away from the second positioning block is fixedly connected to the inner wall of the positioning groove, the positioning spring is slidably sleeved in the limiting rod, and the side of the limiting rod away from the first positioning block is inclined and extends out of the outer side of the rotating disk.

[0019] By adopting the above technical solution, in the initial state, the end of the limiting rod near the slot is located inside the insertion hole, and the friction between the limiting groove and the first positioning block, and between the slider and the slide groove, is relatively strong. When installing the injection needle assembly, one end of the injection needle assembly is inserted into the slot and the slider is inserted into the slide groove. At this time, the first positioning block is inserted into the limiting groove and abuts against the inner wall of the rotating groove away from the cleaning tank. When the starting cylinder drives the limiting cylinder to insert into the rotating groove, during this process, the inclined surface of the limiting cylinder abuts against the limiting rod and pushes the limiting rod. Moving towards the slot, the second positioning block stretches the positioning spring, causing it to deform. At this point, the end of the limiting rod near the slot extends into the limiting groove and abuts against the side of the first positioning block away from the rotating shaft. The limiting rod then fixes the first positioning block, preventing it from being pulled out of the limiting groove. This, in turn, fixes the injection needle assembly, preventing it from coming out of the slot during cleaning. This ensures the safety and stability of the cleaning process and improves the practicality of the appearance inspection mechanism for insulin syringes.

[0020] The present invention is further configured such that: a plurality of limiting blocks are fixedly installed on the side of the second fixing plate near the first fixing plate, the limiting blocks are C-shaped, and a slide rail is fixedly connected to the side of the first fixing plate near the second fixing plate, the slide rail being slidably connected to the limiting blocks.

[0021] By adopting the above technical solution, cylinder two is activated, which drives the support block to move. The support block drives the fixed plate two to move, and the fixed plate two simultaneously drives the mounting plate and motor to move. The movement of the fixed plate two can effectively increase the range of movement of the mounting plate, thereby improving the practicality and flexibility of the appearance inspection mechanism for insulin syringes.

[0022] The beneficial effects of this invention are as follows: when an injection needle assembly is aligned with the camera, the starter motor can drive the rotating disk to rotate, and the rotating disk synchronously drives the injection needle assembly to rotate. The camera captures the rotating injection needle assembly, thereby increasing the shooting range of the injection needle assembly, making the detection range of the injection needle assembly more comprehensive, and improving the detection quality of the appearance of the insulin injector.

[0025] To facilitate a clear understanding of the technical means, inventive features, objectives, and effects of this invention, the following detailed description is provided. Figure 1-12 The invention will be further illustrated as shown.

[0026] like Figures 1 to 11As shown, the present invention is an appearance inspection mechanism for an insulin injector, including a base 1, a mounting bracket 25 fixedly mounted on the base 1, a fixing plate 2 fixedly mounted on the mounting bracket 25, a first stabilizing groove 45 extending through the fixing plate 2, a support block 47 slidably connected within the first stabilizing groove 45, the support block 47 extending through the first stabilizing groove 45, a cylinder 44 fixedly mounted on the mounting bracket 25, the telescopic end of the cylinder 44 fixedly connected to the support block 47, a fixing plate 3 fixedly connected to the support block 47, a mounting plate 4 provided on the fixing plate 3, two rotating shafts rotatably connected to the mounting plate 4, each of the two rotating shafts having a pulley 28 and a pulley 27 rotatably mounted on it respectively, and a driving assembly provided on the fixing plate 3, the driving assembly being able to drive the pulley 28 and the pulley 27 to rotate; An installation box 7 is fixedly installed on the base 1, and a supplementary lighting component is provided on the base 1; A mounting base 10 is fixedly installed on the mounting plate 4. Two rotating grooves 11 are opened on the side of the mounting base 10 away from the mounting plate 2. A rotating groove 24 is opened on the side of the mounting base 10 away from the rotating groove 11. The rotating groove 24 communicates with the rotating groove 11. A rotating shaft 17 is rotatably connected to each of the two rotating grooves 24 through bearings. A rotating disk 12 is fixedly connected to one end of the rotating shaft 17. The other ends of the two rotating shafts 17 extend out of the outer side of the mounting base 10 through the rotating grooves 24 and are fixedly connected to the two rotating shafts respectively. The rotating disk 12 is slidably connected to the rotating groove 11. An injection needle assembly 14 is provided on the rotating disk 12. A limiting mechanism that can limit the injection needle assembly 14 is provided on the rotating disk 12. The base 1 is equipped with a cleaning component that can clean the injection needle assembly 14.

[0027] like Figures 1 to 8 As shown, the drive assembly includes a motor 31, which is fixedly mounted on the mounting plate 4. The output shaft of the motor 31 is poweredly connected to a pulley 3 29. A fourth pulley 55 is fixedly connected to the rotating shaft on which the second pulley 28 is mounted. A synchronous belt 30 is rotatably connected between the fourth pulley 55 and the third pulley 29, and between the second pulley 28 and the first pulley 27.

[0028] In this scheme, the fourth pulley 55, pulley three 29, pulley two 28 and pulley one 27 are all synchronous pulleys.

[0029] In use, the starting motor 31 can drive pulley 3 29 to rotate. Because pulley 3 29 and the fourth pulley 55 are connected by a synchronous belt 30, the rotation of pulley 3 29 can drive the fourth pulley 55 and pulley 2 28 to rotate. The rotation of pulley 2 28 synchronously drives pulley 1 27 to rotate. The rotation of pulley 1 27 and pulley 2 28 drives two rotating shafts to rotate. The rotation of the rotating shafts synchronously drives the rotating shaft 17 to rotate. The rotation of the rotating shaft 17 synchronously drives the rotating disk 12 to rotate.

[0030] like Figures 1 to 7 As shown, a camera 42 is fixedly installed inside the mounting box 7. The injection needle assembly 14 includes a first positioning block 16 and a needle body 13. The first positioning block 16 is fixedly sleeved on the injection needle assembly 14, and the needle body 13 is disposed inside the injection needle assembly 14. The injection needle assembly 14 and the needle body 13 are both existing technologies of existing pen insulin injectors, and will not be described in detail here.

[0031] like Figure 11 As shown, a cylinder 46 is fixedly installed on the fixed plate 2 3. A connecting block 48 is fixedly connected to the telescopic end of the cylinder 46. A second stabilizing groove 49 is opened through the fixed plate 2 3. The connecting block 48 passes through the second stabilizing groove 49 and is slidably connected to the second stabilizing groove 49. The connecting block 48 is fixedly connected to the mounting plate 4.

[0032] The starting cylinder 46 can drive the connecting block 48 to move. The movement of the connecting block 48 synchronously drives the mounting plate 4 to move. The movement of the mounting plate 4 synchronously drives the fixed seat 10, the rotating shaft 17, the motor 31, the pulley 29, the pulley 28, the pulley 27, etc. to move synchronously. This allows the positions of the two rotating shafts 17 and the rotating disk 12 to be adjusted. During the movement of the rotating disk 12, the injection needle assembly 14 can be aligned with the camera 42. The camera 42 takes pictures of the injection needle assembly 14 on the rotating disk 12 through the through slot 52, thereby performing an appearance inspection of the injection needle assembly 14 without manual inspection, saving manpower.

[0033] like Figures 1 to 7 As shown, the supplementary lighting assembly includes a rotating illumination lamp 26, which is fixedly mounted on a base 1. A supplementary lighting chamber 6 is fixedly mounted on the base 1, and a supplementary light is installed inside the supplementary lighting chamber 6. A through slot 52 is provided through the supplementary lighting chamber 6, and the supplementary light inside the supplementary lighting chamber 6 faces the injection needle assembly 14.

[0034] When an injection needle assembly 14 is aligned with the camera 42, the starter motor 31 drives the rotating disk 12 to rotate. The rotation of the rotating disk 12 synchronously drives the injection needle assembly 14 to rotate. The camera 42 captures images of the rotating injection needle assembly 14, thereby increasing the shooting range of the injection needle assembly 14 and making the detection range of the injection needle assembly 14 more comprehensive. This improves the detection quality of the appearance of the insulin syringe. The lights in the supplementary lighting chamber 6 illuminate the needle body 13 and the injection needle assembly 14 to provide supplementary lighting, making the images captured by the camera 42 clearer and ensuring the stability of the detection.

[0035] like Figures 1 to 10As shown, the cleaning assembly includes a cleaning tank 8, a cylinder 9 fixedly mounted on a base 1, the telescopic end of the cylinder 9 being fixedly connected to the cleaning tank 8, the cleaning tank 8 being hollow inside, a limiting cylinder 37 fixedly connected to one side of the cleaning tank 8, a guide bucket 39 fixedly connected to the lower side of the limiting cylinder 37, a sealing ring 38 fixedly connected to the side of the limiting cylinder 37 away from the cleaning tank 8, the inner wall of the guide bucket 39 being inclined, the inclined surface of the bottom wall of the guide bucket 39 being inclined downward from the limiting cylinder 37 to the cleaning tank 8, a connecting pipe 51 fixedly connected to the lower side of the guide bucket 39, the connecting pipe 51 communicating with the inside of the guide bucket 39, a filter box 40 fixedly connected to the end of the connecting pipe 51 away from the guide bucket 39, and a filter cotton 41 fixedly connected inside the filter box 40.

[0036] like Figures 9 to 10 As shown, the cleaning assembly also includes a pump body 36 and a pump body 54. Pump body 36 and pump body 54 are fixedly installed inside the cleaning tank 8. An air pipe 33 is fixedly installed on the limiting cylinder 37. The limiting cylinder 37 and the air pipe 33 are connected internally. The end of the air pipe 33 away from the limiting cylinder 37 is fixedly connected to the upper surface of the cleaning tank 8. The air pipe 33 is connected to the cleaning tank 8. A liquid pipe 34 is fixedly connected to the limiting cylinder 37. The end of the liquid pipe 34 away from the limiting cylinder 37 passes through the cleaning tank 8 and is fixedly connected to the output end of the pump body 36. A liquid pipe 35 is fixedly connected to the lower side of the filter box 40. The end of the liquid pipe 35 away from the filter box 40 passes through the cleaning tank 8 and is fixedly connected to the input end of the pump body 54. The filter box 40 is connected to the liquid pipe 35, and the liquid pipe 34 is connected to the limiting cylinder 37.

[0037] In this scheme, solenoid valves are installed on liquid pipe 34, connecting pipe 51 and liquid pipe 35, and a PLC controller is installed on the base 1. The solenoid valves are all electrically connected to the PLC controller.

[0038] When cleaning the needle body 13, the cylinder 9 is activated to move the cleaning tank 8. During this movement, the limiting cylinder 37 moves, causing the side of the limiting cylinder 37 furthest from the cleaning tank 8 to insert into the rotating groove 11. This causes the sealing ring 38 to abut against the inner wall of the rotating groove 11 furthest from the cleaning tank 8. During this process, the limiting cylinder 37 is encased within the injection needle assembly 14. As the cleaning tank 8 continues to move, the sealing ring 38 is compressed, sealing the limiting cylinder 37. At this time, the pump body 36 is activated. The solenoid valve on the liquid pipe 35 closes, sealing the liquid pipe 35. The solenoid valve on the liquid pipe 34 opens, and the solenoid valve on the connecting pipe 51 closes, releasing the cleaning solution from the cleaning tank 8. The cleaning fluid is transported to the limiting cylinder 37 through the cleaning tank 8. At this time, the air in the limiting cylinder 37 is squeezed and discharged into the cleaning tank 8 through the air pipe 33. When an appropriate amount of cleaning fluid is injected into the limiting cylinder 37, the cleaning fluid submerges the injection needle assembly 14 and the needle body 13. At this time, the starting motor 31 is started, which can drive the injection needle assembly 14 and the needle body 13 to rotate. During the rotation of the injection needle assembly 14 and the needle body 13, the cleaning fluid cleans the injection needle assembly 14 and the needle body 13, cleaning the burrs and dirt adhering to the surface of the needle body 13. This makes the external inspection quality of the needle body 13 and the injection needle assembly 14 higher and the accuracy stronger, thereby improving the inspection quality of the appearance inspection mechanism of the insulin injector. After cleaning, pump body 2 54 is restarted. At this time, the solenoid valve on the connecting pipe 51 is opened, and pump body 2 54 draws the cleaning fluid in the limiting cylinder 37 into the filter box 40 through the connecting pipe 51. After impurities are filtered by the filter cotton 41, the fluid is discharged into the cleaning tank 8 through the liquid pipe 2 35, realizing the recycling and reuse of the cleaning fluid. The guide bucket 39 can guide the cleaning fluid in the limiting cylinder 37 to prevent the cleaning fluid from remaining in the limiting cylinder 37. When the cleaning fluid in the limiting cylinder 37 is drawn into the filter box 40, the cleaning work of the needle body 13 and the injection needle assembly 14 is completed. The cylinder 9 can be activated to move the cleaning tank 8 away from the injection needle assembly 14, thereby moving the limiting cylinder 37 away from the injection needle assembly 14 and releasing the cover on the injection needle assembly 14. At this time, the cylinder 46 can be activated to move the motor 31, pulley 29, pulley 28, pulley 27, fixed seat 10, rotating shaft 17 and the injection needle assembly 14 positioned on the rotating shaft 17, so that the injection needle assembly 14 is aligned with the camera 42 for detection.

[0039] like Figures 1 to 6 As shown, the limiting mechanism includes a limiting groove 43, which is located on the side of the rotating disk 12 away from the rotating shaft 17. A slot 53 is provided on the inner wall of the limiting groove 43 near the rotating shaft 17. One end of the injection needle assembly 14 can be inserted into the slot 53. A slider 19 is fixedly connected to the outer side of the injection needle assembly 14. A sliding groove 18 is provided on the inner wall of the slot 53. The slider 19 can be inserted into the sliding groove 18. The first positioning block 16 is inserted into the limiting groove 43.

[0040] like Figures 1 to 6 As shown, the limiting mechanism also includes multiple insertion holes 23 opened on the outside of the rotating disk 12. A limiting rod 15 is slidably connected in the insertion hole 23. The insertion hole 23 is connected to the limiting groove 43. A positioning groove 20 is opened in the insertion hole 23 and is connected to the insertion hole 23. A second positioning block 21 is fixedly connected to the limiting rod 15. The second positioning block 21 is slidably connected in the positioning groove 20. A positioning spring 22 is fixedly connected to the side of the second positioning block 21 away from the slot 53. The end of the positioning spring 22 away from the second positioning block 21 is fixedly connected to the inner wall of the positioning groove 20. The positioning spring 22 is slidably sleeved in the limiting rod 15. The side of the limiting rod 15 away from the first positioning block 16 is inclined and extends out of the outside of the rotating disk 12.

[0041] In the initial state, the end of the limiting rod 15 near the slot 53 is located inside the insertion hole 23, and the friction between the limiting groove 43 and the first positioning block 16, and between the slider 19 and the slide groove 18, is relatively strong. When installing the injection needle assembly 14, one end of the injection needle assembly 14 is inserted into the slot 53 and the slider 19 is inserted into the slide groove 18. At this time, the first positioning block 16 is inserted into the limiting groove 43 and abuts against the inner wall of the rotating groove 11 on the side away from the cleaning tank 8. When the starting cylinder 9 drives the limiting cylinder 37 to insert into the rotating groove 11, during this process, the limiting cylinder 37 abuts against the inclined surface of the limiting rod 15 and pushes the limiting rod 15 towards... When the slot 53 moves, the second positioning block 21 stretches the positioning spring 22, causing the positioning spring 22 to deform. At this time, the end of the limiting rod 15 near the slot 53 extends into the limiting groove 43 and abuts against the side of the first positioning block 16 away from the rotating shaft 17. The limiting rod 15 fixes the first positioning block 16 so that the first positioning block 16 cannot be pulled out of the limiting groove 43, thereby fixing the injection needle assembly 14 and preventing the injection needle assembly 14 from coming out of the slot 53 when cleaning the injection needle assembly 14 and the needle body 13. This ensures the safety and stability of cleaning and improves the practicality of the appearance inspection mechanism for insulin syringes.

[0042] When the limiting cylinder 37 moves out of the rotating groove 11, the second positioning block 21 and the limiting rod 15 are reset under the action of the release force of the positioning spring 22, releasing the fixation of the first positioning block 16 and the injection needle assembly 14. The injection needle assembly 14 does not need to be fixed manually, saving manpower.

[0043] like Figure 12As shown, multiple limiting blocks 50 are fixedly installed on the side of the second fixed plate 3 near the first fixed plate 2. The limiting blocks 50 are C-shaped. A slide rail rod 32 is fixedly connected to the side of the first fixed plate 2 near the second fixed plate 3. The slide rail rod 32 is slidably connected to the limiting blocks 50 and passes through the limiting blocks 50. The slidable connection between the limiting blocks 50 and the slide rail rod 32 can improve the stability of the movement of the second fixed plate 3.

[0044] When cylinder 44 is activated, it can move support block 47, which in turn moves fixed plate 3. Fixed plate 3 then moves mounting plate 4 and motor 31, among other things. The movement of fixed plate 3 effectively increases the range of motion of mounting plate 4, thereby improving the practicality and flexibility of the appearance inspection mechanism for insulin injectors.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
