Technical Field

[0001] The utility model belongs to the technical field of injection pen detection equipment, and in particular relates to automatic function testing equipment based on the injection pen. Background Art

[0002] Pen-type injectors are suitable for drugs that require high precision in injection dosage, such as insulin, growth hormone, follicle stimulating hormone, parathyroid hormone, interferon, etc. In recent years, the incidence of diabetes has been increasing year by year. Pen-type injectors represented by insulin injection pens have been widely used. They are favored by patients due to their advantages such as accurate injection dosage, simple operation, and convenient portability. However, at present, there is no unified product standard for domestic injection systems, and the needles and medicine bottles are different. In particular, the indicators and test methods of dosage accuracy are different.

[0003] In the Chinese patent application publication number CN219224166U, a smart insulin injection pen function test device is disclosed, specifically a smart insulin injection pen function test device with accurate testing, reliable results, high testing efficiency, easy operation and low testing cost is disclosed, including a control box assembly, a weight box assembly and a test assembly, which measures the injection action, injection measurement and distance of the smart insulin injection pen, and realizes the test of whether the circuit board and motor of the smart insulin injection pen are operating normally and whether the control measurement function is qualified; in this device, although the mechanical performance test of the injection pen is realized, there is a lack of effective experiments.

[0004] Moreover, the structural components of each injection pen are different, so when conducting structural testing, the structure of each product needs to be customized. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide an automatic function testing device based on an injection pen, which solves the above-mentioned technical problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0008] The cap removal detection mechanism is used to perform a cap removal tension test on the injection pen.

[0009] The injection detection mechanism includes a pressure correction component, an injection platform, a weighing component, and a second transport component. The second transport component transports the injection pen to the pressure correction component for pressure correction, and then transports the injection pen to the injection platform. The second transport component applies downward pressure to inject the liquid medicine in the injection pen into the weighing component at the bottom through the injection platform, and the weight of the injected liquid medicine is measured by the weighing component.

[0010] The damage detection mechanism includes a third transport component and a damage base. After the third transport component clamps the injection pen, it is transported to the damage base and a downward pressure is applied to form a rebound force damage to the shell of the injection pen in the vertical direction.

[0011] The needle detection mechanism includes a fourth transport component and a needle detection component. The fourth transport component transports the damaged injection pen to the needle detection component, and the needle detection component detects the needle tip of the injection pen.

[0015] Furthermore, the cap removal detection mechanism comprises a first moving assembly, a first tension clamping jaw, and a bottom clamping assembly. The first tension clamping jaw moves to the carrying station through the first moving assembly arranged transversely, clamps the transmitted injection pen to the bottom clamping assembly, and clamps the pen cap at the bottom of the injection pen through the bottom clamping assembly. The first tension clamping jaw pulls the injection pen in a vertical direction until the pen cap is separated from the injection pen body, and the tension sensor located on the first tension clamping jaw tests the tension.

[0016] A recovery hole is arranged just below the bottom clamping assembly, so that the detached pen cap can fall off from the recovery hole and be recovered in a centralized manner.

[0017] Furthermore, an optical fiber detection component is provided at the side where the bottom clamping component is located, and whether the pen cap is clamped in place is detected by the optical fiber detection component.

[0018] Furthermore, the injection detection mechanism is provided with a first camera assembly and a reflective panel. The shooting direction of the first camera assembly extends along the direction of the groove opened on the upper surface of the injection platform. At the same time, a reflective panel is provided on the other side of the shooting direction of the first camera assembly to monitor the protruding length of the needle tip of the injection pen through the first camera assembly.

[0019] Furthermore, a through hole is provided at the middle position of the destruction base, for the needle tip of the injection pen to pass through, so that the upper surface of the destruction base forms a support for the injection pen housing.

[0020] Furthermore, the needle detection assembly includes a detection seat, a carrying cylinder, a rotating motor, and a second camera assembly. The two ends of the upper surface of the detection seat are respectively provided with a carrying cylinder and a rotating motor. At the same time, a through hole for the needle tip to penetrate is opened at the bottom of the carrying cylinder, and the rotating motor drives the carrying cylinder to rotate around the center as the axis.

[0021] The second camera assembly is located at the bottom of the detection seat. The rotation of the carrying tube drives the injection pen carried on the upper part to rotate synchronously, and the second camera assembly is used to shoot and record the state of the extended needle tip.

[0022] Furthermore, the needle cap transport component includes a moving track member at the bottom and a placement box at the top. The upper surface of the placement box is provided with a plurality of slots distributed in a row. A silicone body is contained in the slots. The needle tip of the injection pen is inserted into the silicone body of the placement box through the fifth transport component to protect the needle tip of the injection pen, and then the needle tip is transferred out and thrown into the recovery channel on the side.

[0023] The bottom of the placement box is slidably arranged along the transmission direction of the moving track member, so that the entire box can be easily replaced.

[0024] Furthermore, the bearing seat includes a bearing platform and clamping claws arranged on both sides of the bearing platform. The bearing groove in the middle of the bearing platform is used to support the front end of the injection pen, and the clamping claws clamp and fix the injection pen in the vertical direction.

[0025] Furthermore, the testing method of the automatic functional testing device based on the injection pen,

[0031] Beneficial effects of the utility model:

[0032] 1. The cap removal detection mechanism, liquid injection detection mechanism, damage detection mechanism, needle detection mechanism, and needle cap assembly mechanism used in this device cooperate with each other to test the injection pens transported on the carrying station one by one at the same time, greatly improving the test efficiency.

[0033] 2. The side of the liquid injection detection mechanism used in this device is provided with a first camera assembly, that is, while measuring the amount of liquid in the injection pen, the length of the needle tip extending therefrom can also be measured, thus achieving the efficiency of two functions in one station.

[0034] 3. The needle detection mechanism used in this device can use a rotating motor to drive the detection seat to produce self-rotation, that is, it simultaneously drives the injection pen located inside to produce self-rotation. At this time, the needle protruding from the tip is photographed through the second camera assembly. When there is an inclined surface, it means that the needle is normal, which greatly improves the detection efficiency.

[0035] 4. The needle cap assembly mechanism used in this device wraps the tip of the needle by inserting the tested injection pen into the silicone body, effectively protecting the testing environment from the influence of the exposed needle tip. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] like Figure 1 , Figure 2 As shown, an embodiment of the utility model provides an automatic function testing device based on an injection pen, including a cap removal detection mechanism 1, a liquid injection detection mechanism 2, a damage detection mechanism 3, a needle detection mechanism 4, a needle cap assembly mechanism 5, and a carrying station 6. This injection pen generally includes two structures: a pen cap and an injection pen body.

[0051] like Fig.11 , Fig.12 As shown, before loading at the loading station 6, each injection pen is scanned, identified and recorded by a barcode scanning component 101 provided on the side. Each injection pen is provided with a unique and designated QR code, and the performance of the tested injection pen can be fed back to the testing center for record by scanning the barcode scanning component 101.

[0052] The carrying station 6 includes a rotating platform 61 in the middle and multiple groups of bearing seats 62 arranged at evenly spaced positions on the upper surface of the rotating platform 61. The bearing seats 62 clamp the injection pen so that the cap end of the injection pen is placed at the lower end and the body end is placed at the upper end. As the rotating platform 61 rotates, the injection pen in the clamped state is successively transferred to each mechanism for station operation. The bearing seat 62 includes a bearing platform 621 and a clamping claw 622 arranged on both sides of the bearing platform 621. The bearing groove in the middle of the bearing platform 621 is used to support the front end of the injection pen. At the same time, the clamping claw 622 clamps and fixes the position of the injection pen in the vertical direction. This fixing method can clamp the side of the injection pen without generating a squeezing force in the vertical direction, which affects the rebound force of the tip of the injection pen.

[0053] like Figure 3 As shown, the capping detection mechanism 1 is used for performing a capping tension test on an injection pen, and comprises a first moving assembly 11, a first tension clamping jaw 12, and a bottom clamping assembly 13. When in use, the first tension clamping jaw 12 is moved to the carrying station 6 through the transversely arranged first moving assembly 11 (the first moving assembly 11 and the first tension clamping jaw 12 together constitute a first transport assembly), the transported injection pen is clamped onto the bottom clamping assembly 13, and the pen cap at the bottom of the injection pen is clamped by the bottom clamping assembly 13, the first tension clamping jaw 12 pulls the injection pen in a vertical direction (that is, the pen shaft where the injection pen is located extends in a vertical direction) until the pen cap is separated from the injection pen body, and at the same time, the tension sensor 121 located on the first tension clamping jaw 12 tests the tension during pulling, and a recovery hole 131 is provided directly below the bottom clamping assembly 13, and the bottom clamping assembly 13 is opened to allow the detached pen cap to fall off from the recovery hole 131 and be recovered in a centralized manner. In addition, an optical fiber detection component 132 is provided on the side where the bottom clamping component 13 is located. The optical fiber detection component 132 detects whether the pen cap is clamped in place (i.e., whether the bottom clamping component 13 effectively clamps the pen cap) to prevent the injection pen from falling off directly when being pulled out.

[0054] This test method can test the minimum force required to pull out the pen cap in the vertical direction of the entire test pen, and the detection measurement accuracy can be controlled within 0.2N.

[0055] like Figure 4As shown, the injection detection mechanism 2 includes a pressure correction component 21, an injection platform 22, a weighing component 23, and a second transport component 24. The second transport component 24 transports the injection pen from the carrying station 6 to the pressure correction component 21 for pressure correction (to ensure that the pressure applied is consistent with the pressure measurement result of the sensor, thereby ensuring the accuracy of the measurement result), and then transports the injection pen to the injection platform 22 (at this time, the needle of the injection pen passes through the upper surface of the injection platform 22 and is injected into the weighing component 23 at the lower end). The second transport component 24 applies downward pressure to the injection pen to inject the liquid medicine in the injection pen into the weighing component 23 at the bottom through the injection platform 22, and then measures the weight of the injected liquid medicine through the weighing component 23 until the liquid medicine in the injection pen is completely injected (at this time, the weighed weight of the liquid medicine is the weight of the liquid medicine injected from the injection pen), and simultaneously records the constant pressure used by the second transport component 24 during the pressure injection process and the total duration from the start to the end of the injection.

[0056] At the same time, the injection detection mechanism 2 is provided with a first camera assembly 25 (located on the side of the injection platform 22) and a reflective panel 251. The shooting direction of the first camera assembly 25 extends along the direction of the groove opened on the upper surface of the injection platform 22 (this groove can form a barrier to the injection pen housing, and the needle tip located in the middle can pass through the depth of the groove and be placed in the weighing assembly 23). The reflective panel 251 is arranged on the other side of the shooting direction of the first camera assembly 25 (to reduce the reflection of the first camera assembly 25 during the shooting process). The first camera assembly 25 is used to monitor the extended length of the injection pen needle tip, that is, whether the length of the injection pen needle tip at this time meets the actual production requirements when photographed by the first camera assembly 25.

[0057] like Figure 5 As shown, the destruction detection mechanism 3 includes a third transport component 31 and a destruction base 32. After the third transport component 31 clamps the injection pen, it is transported to the destruction base 32 (a through hole is provided in the middle position of the destruction base 32 for the needle tip of the injection pen to pass through, and the upper surface of the destruction base 32 forms a support for the injection pen shell). When pressure is applied, the shell of the injection pen is destroyed by the rebound force in the vertical direction until the rebound structural component between the outer shell and the inner shell of the injection pen is destroyed, and the needle tip located in the middle is a through hole that penetrates the middle part, so it will not be affected, and the third transport component is used to maintain a lasting time when pressed down, so as to determine how long the holding force of the injection pen can last.

[0058] like Figure 6 , Figure 7As shown, the needle detection mechanism 4 includes a fourth transport component 41 and a needle detection component 42. The fourth transport component 41 transports the damaged injection pen to the needle detection component 42, and the needle tip of the injection pen is detected by the needle detection component 42. The needle detection component 42 includes a detection seat 421, a carrying cylinder 422, a rotating motor 423, and a second camera component 424. The two ends of the upper surface of the detection seat 421 are respectively provided with a carrying cylinder 422 and a rotating motor 423. At the same time, a through hole for the needle tip to pass through is opened at the bottom where the carrying cylinder 422 is located (the middle part of which is used to support the lower part of the injection pen). At this time, the rotating motor 423 drives the carrying cylinder 422 to rotate around the center as the axis. This structure will not cause damage to the tip of the injection pen. By rotating the injection pen, the needle tip bevel of the injection pen tip is found. When the needle tip bevel is complete, the injection pen tip is complete and meets the detection requirements. When the needle tip bevel is incomplete (anisotropic surface or bending surface appears), an alarm message is generated to indicate that the detection is unqualified.

[0059] like Figure 8 As shown, the second camera assembly 424 is located at the bottom position of the detection seat 421, and the rotation of the supporting tube 422 drives the injection pen carried on the upper part to rotate synchronously (at this time, the structure between the inner shell and the outer shell of the injection pen is damaged, so when the fourth transfer assembly 41 rotates, the pen tip exposed at the lower end will also rotate synchronously), and the second camera assembly 424 shoots and records the state of the extended needle tip (at this time, the normal needle tip presents a bevel incision state, and the position of the bevel incision can be effectively found by rotation without manual rotation).

[0060] like Fig. 9 , Fig.10 As shown, after the performance test of the conventional injection pen, the needle tip is exposed. Directly discarding the needle tip may cause secondary harm to the users. The needle cap assembly mechanism 5 includes a fifth transfer component 51 and a needle cap transfer component 52. The fifth transfer component 51 inserts the tip of the injection pen into the needle cap transfer component 52 and then transfers it out.

[0061] The needle cap transport component 52 includes a moving track component 521 at the bottom and a placement box 522 at the top. The upper surface of the placement box 522 is provided with a plurality of groups of slots distributed in an array, and silicone bodies are contained in the slots. The needle tip of the injection pen is inserted into the silicone body of the placement box 522 through the fifth transport component 51 to form a wrapped protection for the needle tip of the injection pen, and then the needle tip is transferred out and thrown into the recovery channel on the side. A group of silicone bodies is inserted into each group of injection pens, and then the placement box 522 is adjusted to the position where the moving track component 521 is pushed forward, thereby reducing the horizontal movement stroke of the fifth transport component 51.

[0062] At the same time, the bottom of the placement box 522 is slidably arranged along the transmission direction of the moving track member 521, which can facilitate the overall replacement.

[0063] When used specifically, the test method of the automatic functional test equipment based on the injection pen is:

[0064] S1. First, the injection pen to be tested is marked and sent to the support seat 62 of the support station 6. Then, through the rotation of the rotating platform 61, the support seat 62 holding the injection pen to be tested is transported to each testing station one by one for testing. After the testing of each station is completed, it is placed back on the support seat 62, and with the rotation of the rotating platform 61, the support seat 62 is synchronously transported to another station without affecting the normal transportation work of the previous station and the next station.

[0065] S2, the capping detection mechanism 1 is used to perform a capping tension test on the injection pen to be tested, and then the injection pen after capping is transferred to the supporting seat 62 again, and then transferred to the liquid injection detection mechanism 2 through the rotation of the rotating platform 61, and the pen cap at the bottom is directly recycled through the recycling device.

[0066] S3, the quantitative injection test of the injection pen is performed through the injection detection mechanism 2. This quantitative injection mechanism does not exist.

[0067] Then it is transferred to the destruction detection mechanism 3;

[0068] S4, performing a shell destruction test on the injection pen through the destruction detection mechanism 3, and then transferring the injection pen to the needle detection mechanism 4;

[0069] S5, the needle tip of the injection pen is inspected by the needle inspection mechanism 4, and then the needle tip is transferred to the needle cap assembly mechanism 5, and the injection pen after the inspection is transferred out.

[0070] The testing process at each workstation is carried out independently, which facilitates the testing of multiple injection pens at the same time and greatly improves the testing efficiency.

[0071] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
