Description

Technical Field

[0001] This application relates to the field of testing machine technology, and in particular to a needle tip qualification test device. Background Technology

[0002] As a core component of medical devices (such as syringes and infusion sets), the quality of needles directly affects patient safety and treatment outcomes. Therefore, various safety tests are conducted on needles before use.

[0003] A Chinese patent, titled "A Medical Microneedle Detection Device," publication number CN 215179774U, published on 2021-12-14, describes a medical microneedle detection device comprising a base. Support columns are fixedly connected to the four corners of the lower end of the base. A telescopic controller is fixedly connected to the middle of the upper end of a horizontal plate. The output end of the telescopic controller passes through the horizontal plate and is fixedly connected to a push plate. A comparison device is fixedly connected to the front end of the push plate. A base plate is fixedly connected to the middle of the upper end of the base. A stabilizing plate is fixedly connected to the left end of the base plate. A pushing device is fixedly connected to the left end of the stabilizing plate. A fixing device is fixedly connected to the upper end of the pushing device. Sliding grooves are formed at the front and rear of the upper end of the base plate. A control screen is fixedly connected to the right side of the upper end of the base. This medical microneedle detection device, by incorporating a comparison device throughout the device, can detect whether the medical needle tip is complete, thereby determining whether the needle tip angle is qualified, thus improving the accuracy of microneedle detection.

[0004] Although the device pushes the needle to the comparison device for comparison to detect whether the needle is qualified, only one needle can be tested at a time. Only after testing one needle can the next needle be placed on the fixing device for testing. When testing a large number of needles, the staff needs to compare each needle individually, which increases the workload of the staff and reduces the working efficiency of the device. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a needle qualification test device, which solves the problem of increased workload for workers and reduced device efficiency when testing large batches of needles.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: a needle thread testing device, comprising a control box and a detection module fixedly installed on the top surface of the control box. The detection module includes a conveying component, a lifting component, a transverse sliding component, and a base. The transverse sliding component is fixedly installed on one side of the base. The lifting component is slidably connected to the transverse sliding component and perpendicular to each other. A testing component is fixedly installed on the side of the lifting component away from the transverse component. Two clamping components are fixedly installed on the side of the lifting component away from the transverse component, respectively symmetrical to both sides of the testing component. A first fixing block and a second fixing block are fixedly installed on the top surface of the base. Two fixed blocks are located below the clamping assembly. One end of the conveying assembly is connected to a material box, and the other end of the conveying assembly is fixedly connected to one side of the first fixed block. A slot is opened on the top surface of the first fixed block, and a sensor is fixedly installed on the top surface of the first fixed block. A controller is fixedly installed on one side of the transverse sliding assembly. The testing assembly includes a fixed plate fixedly installed on the lifting assembly and a telescopic plate fixedly installed on the side of the fixed plate away from the lifting assembly. A pin sleeve is fixedly installed on the bottom surface of the telescopic plate. The opening of the pin sleeve faces downward, and a needle detection mold is inserted into the pin sleeve. The controller is electrically connected to the conveying assembly, the lifting assembly, the transverse sliding assembly, the clamping assembly, the testing assembly, and the sensor.

[0007] Furthermore, a U-shaped fixing frame is fixedly installed on the top surface of the base, and a conveying pipe is fixedly installed between the two sides of the U-shaped fixing frame. The U-shaped fixing frame and the first fixing block are symmetrically distributed on both sides of the second fixing block. Arc-shaped sliding grooves are opened on the opposite sides of the U-shaped fixing frame, and screws are fixedly installed on the opposite sides of the conveying pipe. The screws are slidably connected to the arc-shaped sliding grooves, and a bolt is spirally connected to the end of the screw away from the conveying pipe.

[0008] Furthermore, a recycling bin is placed on the top surface of the base, located between the first fixing block and the second fixing block. Two limiting blocks are fixedly installed on the top surface of the base, with one side of each limiting block abutting the opposite side of the recycling bin.

[0009] Furthermore, a collection box is fixedly installed on the side of the base away from the conveying assembly, and the collection box is located directly below the lower end of the conveying pipe.

[0010] Furthermore, a support plate is fixedly installed at the bottom of the conveying assembly, and the material box is placed on the top surface of the support plate.

[0011] Furthermore, four telescopic support columns are fixedly installed on the bottom surface of the support plate, and are arranged in a rectangular array on the bottom surface of the support plate.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] When using the device, the needles to be tested are placed in the material box. The conveying component, consisting of a motor and belt, is activated by the operator. The conveying component is then started, sending the needles to be tested into the slots on the surface of the first fixed block. The sensor then sends a signal to the controller, stopping the conveying component. The controller then activates the lifting and sliding components, causing the clamping and testing components to move up and down and slide left and right. The clamping component holds one needle to be tested and places it on the top surface of the second fixed block. When the needle is removed, the conveying component starts, sending the next needle into the slot. The needle to be tested is then inserted into a specific needle detection mold on the testing component to check if it is qualified. If qualified, one of the clamping components removes it for collection; if not qualified, the other clamping component removes it for recycling. This cycle allows the device to perform batch testing without requiring manual testing, effectively improving the device's efficiency.

[0014] When collecting qualified needles, the screw can be slid in the arc-shaped groove to adjust the delivery tube to a suitable tilt angle, preventing the needles from falling onto the delivery tube and causing damage, thus effectively improving the practicality of the device.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Example, refer to Figure 1 as well as Figure 2A needle thread testing device includes a control box 1 and a detection module 2 fixedly installed on the top surface of the control box 1. The detection module 2 includes a conveying component 21, a lifting component 22, a transverse sliding component 23, and a base 25. The transverse sliding component 23 is fixedly installed on one side of the base 25. The lifting component 22 is slidably connected to the transverse sliding component 23 and is perpendicular to it. A test component 24 is fixedly installed on the side of the lifting component 22 away from the transverse component. Two clamping components 26 are fixedly installed on the side of the lifting component 22 away from the transverse component, respectively symmetrical to both sides of the test component 24. A first fixing block 212 and a second fixing block 259 are fixedly installed on the top surface of the base 25. The first fixing block 212 and the second fixing block 259 are located below the clamping components 26. One end of the conveying component 21... The material box 211 is connected, and the other end of the conveying component 21 is fixedly connected to one side of the first fixed block 212. The top surface of the first fixed block 212 is provided with a slot 213. The top surface of the first fixed block 212 is fixedly installed with a sensor 214. The side of the transverse sliding component 23 is fixedly installed with a controller 231. The test component 24 includes a fixed plate 241 fixedly installed on the lifting component 22 and a telescopic plate 242 fixedly installed on the side of the fixed plate 241 away from the lifting side. The bottom surface of the telescopic plate 242 is fixedly installed with a pin sleeve 243. The opening of the pin sleeve 243 faces downward. A needle detection mold 244 is inserted into the pin sleeve 243. The controller 231 is electrically connected to the conveying component 21, the lifting component 22, the transverse sliding component 23, the clamping component 26, the test component 24, and the sensor 214. When using the device, the needle to be tested is placed in the material box 211, and the operator starts the control box 1. The conveying component 21, consisting of a motor and a belt, is then activated to transport the needle to be tested to the slot 213 on the surface of the first fixed block 212. The sensor 214 then sends a signal to the controller 231, and the conveying component 21 stops running. The controller 231 then activates the lifting component 22 and the lateral sliding component 23, which drive the clamping component 26 and the testing component 24 to move up and down and slide left and right. The clamping component 26 clamps the needle to be tested and places it on top of the second fixed block 259. When a needle is clamped away, the conveying component 21 is activated to deliver the next needle to the slot 213. Then, the needle to be tested is inserted into the needle detection mold 244 on the testing component 24 to test whether the needle is qualified. If it is qualified, one of the clamping components 26 clamps it away for collection. If it is unqualified, the other clamping component 26 clamps it away for recycling. This device enables batch testing without the need for manual testing one by one. If it is necessary to test needles of other testing standards, other needle detection molds 244 can be replaced and clamped into the needle insertion sleeve 243, which effectively improves the working efficiency of the device.

[0020] Reference Figure 1A U-shaped fixing frame 251 is fixedly installed on the top surface of the base 25. A conveying pipe 252 is fixedly installed between the two sides of the U-shaped fixing frame 251. The U-shaped fixing frame 251 and the first fixing block 212 are symmetrically distributed on both sides of the second fixing block 259. Arc-shaped grooves 253 are respectively opened on the opposite sides of the U-shaped fixing frame 251. Screws 254 are fixedly installed on the opposite sides of the conveying pipe 252. The screws 254 are slidably connected to the arc-shaped grooves 253. A bolt 255 is screwed to the end of the screws 254 away from the conveying pipe 252. When collecting qualified needles, the conveying pipe 252 can be adjusted to a suitable tilt angle by sliding the screws 254 in the arc-shaped grooves 253, preventing the needles from falling onto the conveying pipe 252 and causing damage, thus effectively improving the practicality of the device.

[0021] Reference Figure 1 A recycling bin 256 is placed on the top surface of the base 25, located between the first fixing block 212 and the second fixing block 259. Two limiting blocks 257 are fixedly installed on the top surface of the base 25, with one side of each limiting block 257 abutting against the opposite side of the recycling bin 256. When removing defective needles, they can be clamped into the recycling bin 256 by the clamping assembly 26 for recycling, effectively improving the environmental friendliness of the device.

[0022] Reference Figure 1 A collection box 258 is fixedly installed on the side of the base 25 away from the conveying assembly 21, and the collection box 258 is located directly below the lower end of the conveying tube 252. When collecting qualified needles, the clamping assembly 26 clamps them into the conveying tube 252, and then the needles slide down into the collection box 258 through the conveying tube 252, which effectively improves the working efficiency of the device.

[0023] Reference Figure 1 A support plate 215 is fixedly installed at the bottom of the conveying assembly 21, and the material box 211 is placed on the top surface of the support plate 215. When using the device, the operation of the conveying assembly 21 may cause slight vibration of the device. The support plate 215 provides support and stability, effectively improving the stability of the device.

[0024] Reference Figure 1 Four telescopic support columns 11 are fixedly installed on the bottom surface of the support plate 215, and are arranged in a rectangular array on the bottom surface of the support plate 215. When it is necessary to adjust the height of the material, the height of the material box 211 and the conveying assembly 21 can be adjusted by adjusting the telescopic support columns 11 through their telescopic nature, which effectively improves the convenience of the device.

[0025] Working principle:

[0026] When using the device, first, the screw 254 is slid within the arc-shaped groove 253 to adjust the conveying tube 252 to a suitable tilt angle. Then, the needle to be tested is placed in the material box 211, and the conveying assembly 21 is started to deliver the needle to be tested to the slot 213 on the surface of the first fixing block 212. The sensor 214 then sends a signal to the controller 231, and the conveying assembly 21 stops operating. The controller 231 then starts the lifting assembly 22 and the lateral sliding assembly 23, causing the clamping assembly 26 and the testing assembly 24 to move up and down and slide left and right. The clamping assembly 26 clamps the needle to be tested and places it in the second... When a needle is clamped, the top surface of the fixing block 259 activates the conveying component 21 to transport the next needle into the slot 213. Then, the needle is passed through a specific needle detection mold 244 on the testing component 24. The testing component 24 slides down and inserts the needle to be tested into the needle detection mold 244 to check whether the needle is qualified. If it is qualified, one of the clamping components 26 clamps it and places it in the collection box 258 for collection. If it is unqualified, the other clamping component 26 clamps it and places it in the recycling box 256 for recycling. This cycle allows the device to perform batch testing without the need for manual testing, effectively improving the working efficiency of the device.

[0027] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
