Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of insulin needle processing, and specifically relates to a fully automatic insulin built-in needle assembly device. Background Art
[0002] Insulin is a protein hormone secreted by pancreatic islet β cells in the pancreas stimulated by endogenous or exogenous substances such as glucose, lactose, ribose, arginine, glucagon, etc. As a drug for treating diabetes, insulin is mainly administered by subcutaneous injection to enable patients to absorb it quickly for treatment purposes. When injecting insulin, an insulin needle is required, and insulin needles are disposable items. Therefore, during production, fully automatic assembly equipment is often used. When the insulin built-in needle is fully automatically assembled on the production line, it usually includes various steps such as part preparation, needle seat feeding, needle tip picking and insertion, pusher installation, spring installation, oil immersion lubrication, testing, and packaging. Among them, the process of oil immersion lubrication for the insulin built-in needle is very important during assembly, which is an important step to reduce friction and protect the needle tip during subsequent use of the insulin built-in needle.
[0003] However, when the existing built-in needle assembly equipment performs oil immersion treatment, the needle tip is often immersed in an open oil storage tank and then removed from the oil tank after oil immersion. At this time, a certain amount of excess oil will adhere to the surface of the needle tip. Some light mineral oils or synthetic oils with low viscosity have good fluidity and are prone to dripping from the oil-immersed needle tip under the action of gravity. Moreover, when the assembly equipment transfers the needle tip, the speed is often relatively fast, making it easier to occur dripping and splashing phenomena. Therefore, during a large amount of long-term production, the dripping and splashing oil will cause certain pollution to the processing environment and also result in waste of oil.
[0004] Therefore, we propose a fully automatic insulin built-in needle assembly device to solve the above-mentioned problems. Summary of the Invention
[0005] Aiming at the problem that when the existing built-in needle assembly equipment performs oil immersion treatment, the needle tip is often immersed in an open oil storage tank and then removed from the oil tank after oil immersion. At this time, a certain amount of excess oil will adhere to the surface of the needle tip. Some light mineral oils or synthetic oils with low viscosity have good fluidity and are prone to dripping from the oil-immersed needle tip under the action of gravity. Moreover, when the assembly equipment transfers the needle tip, the speed is often relatively fast, making it easier to occur dripping and splashing phenomena. Therefore, during a large amount of long-term production, the dripping and splashing oil will cause certain pollution to the processing environment and also result in waste of oil, the purpose of the present invention is to provide a fully automatic insulin built-in needle assembly device.
[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: a fully automatic insulin built-in needle assembly device, including a working frame and a push-pull mechanism. On one side above the working frame, a second push cylinder is installed, and a single chuck is installed on the lower side of the output end of the second push cylinder. On one side below the second push cylinder, a third push cylinder is provided, and an oil immersion tank is installed at the upper end of the third push cylinder. The push-pull mechanism for vibrating and removing oil is arranged on both sides inside the oil immersion tank. The push-pull mechanism includes a driving gear installed in the middle of the lower part inside the oil immersion tank. On both sides below the driving gear, driven gears are connected, and a screw rod is fixed on the other side of the driven gear. A sliding block is arranged in the middle of the screw rod, and a connecting rotating rod is installed above the sliding block. At the top of the connecting rotating rod, a first piston disk is installed, and a first piston cylinder is arranged outside the first piston disk. In the middle of the upper part of the first piston cylinder, a solenoid valve is installed, and an installation joint is connected above the solenoid valve. On one side above the installation joint, a second piston cylinder is connected, and a piston push rod is arranged at the front end inside the second piston cylinder. At the front end of the piston push rod, a pressure head is installed, and an ultrasonic vibration head is installed in the middle of the inner side of the pressure head.
[0007] Further, a feeding turntable is installed on the other side above the working frame, and receiving sockets are annularly distributed outside the feeding turntable. A first push cylinder is installed in the middle above the working frame.
[0008] Further, a lifting frame is arranged at the top of the first push cylinder, and a rotating seat is installed in the middle of the front end of the lifting frame. A double chuck is installed at the front end of the rotating seat, and a needle is clamped at the end of the double chuck.
[0009] Further, guide rods are fixed on both sides in the middle of the sliding block, and the driving gear is rotationally connected to the screw rod through the driven gear. The sliding block is slidably connected to the inner wall of the oil immersion tank through the screw rod and the guide rods. The first piston disk is slidably connected to the first piston cylinder through the sliding block and the connecting rotating rod.
[0010] Further, a pressure relief valve is connected behind the second piston cylinder, and the pressure relief valve, the second piston cylinder, the installation joint and the solenoid valve are connected and communicated. The solenoid valve is connected and communicated with the first piston cylinder. An air inlet valve is connected above one side outside the first piston cylinder.
[0011] Further, an oil immersion mechanism for replaceable oil immersion is arranged in the middle inside the oil immersion tank. The oil immersion mechanism includes a third piston cylinder communicated with the outside of the middle of the first piston cylinder, and an air guide pipe is connected below one side of the third piston cylinder.
[0012] Further, the other side above the air guide pipe is communicated with a fourth piston cylinder, and a second piston disk is arranged below the inside of the fourth piston cylinder. The fourth piston cylinder, the air guide pipe and the third piston cylinder are connected and communicated.
[0013] Further, a manifold pipe is connected above the middle part of the air duct, and an air charging bag is arranged on one side above the manifold pipe. The manifold pipe is communicated with the air duct.
[0014] Further, a liquid inlet valve is installed on one side outside the upper part of the fourth piston cylinder, a liquid guide pipe is connected above the liquid inlet valve, and an oil storage cavity is arranged at the top of the liquid guide pipe.
[0015] Further, an oil outlet valve is installed on one side below the outside of the fourth piston cylinder, a lower oil pipe is connected below the oil outlet valve, and an oil collection cavity is connected below the lower oil pipe.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By the upward movement of the first piston disc, the clamping of the needle head by the pressing head can be finally achieved, and the high-frequency vibration of the ultrasonic vibration head in the pressing head on the needle head after the needle head is immersed in oil can make the excess oil liquid on the surface of the needle head vibrate rapidly to separate from the needle head, avoiding the problem that the oil liquid is likely to drip from the immersed needle head under the action of gravity, and the problem of dripping and splashing that is likely to occur when the assembly equipment quickly transfers the needle head, which is beneficial to ensuring the cleanliness of the processing environment and avoiding the waste of oil liquid. Moreover, under the action of high-frequency mechanical force, the adhesion between the oil liquid and the needle head and the internal cohesion of the oil liquid itself are destroyed, making the oil liquid easier to separate into small oil droplets from the surface of the needle head, thereby improving the thoroughness of oil removal.
[0017] 2. By the up and down movement of the first piston disc, the left and right movement of the gas in the third piston cylinder is finally caused to drive the up and down movement of the second piston disc, so that the fourth piston cylinder can finally realize the reciprocating oil filling and oil discharging process, thereby realizing the automatic replacement of the oil liquid during oil immersion, avoiding the problem that the oil liquid will gradually mix with pollutants such as impurities and metal chips during the oil immersion process and affect the subsequent use of the needle head. At the same time, the replaced oil liquid can ensure that each needle head is immersed in new oil liquid, avoiding the problem that the oil liquid in the large oil immersion tank will deteriorate due to long-term unused, and at the same time, there is no need for manual regular replacement of the oil liquid, avoiding the equipment shutdown caused by the replacement of the oil liquid, enabling the oil immersion operation to be carried out continuously, improving the utilization rate of the production equipment, and further enhancing the overall production efficiency.
[0018] 3. Through the up-and-down movement of the first piston disc within the first piston cylinder, and by utilizing the transmission of air pressure, the present invention can ultimately achieve the functions of synchronously immersing the needle in oil, changing the oil, and vibrating to remove excess oil. This can enhance the continuity and synchronism of the equipment, significantly improving production efficiency. The continuous and collaborative operation mode helps ensure that each needle undergoes consistent processing conditions during the oil immersion and oil removal processes, reducing the differences caused by different equipment or different operation steps, thereby enhancing the stability and consistency of product quality. In the production of insulin pen needles, this helps ensure that the performance and quality of each needle meet high standards and reduces the defective rate. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode
[0021] The present invention will be further described below in conjunction with specific embodiments.
[0022] To solve the problem that the needle head is prone to dripping and splashing after oil immersion, as Figure 1 - Figure 8 shown: Fully automatic insulin built-in needle assembly equipment, including a working frame 1 and two sets of push-pull mechanisms 13 symmetrically arranged below the inside of the immersion oil tank 12. On one side above the working frame 1, a second push cylinder 9 is installed using a bracket, and a single chuck 10 is installed on the lower side of the output end of the second push cylinder 9. The single chuck 10 is composed of an existing clamping cylinder and a soft chuck. On one side below the second push cylinder 9, a third push cylinder 11 is arranged, and an immersion oil tank 12 is installed at the upper end of the third push cylinder 11. On the other side above the working frame 1, a feeding turntable 2 is installed. The feeding turntable 2 is an existing feeding tray driven by a servo motor, and receiving sockets 3 are annularly distributed on the outside of the feeding turntable 2. The receiving sockets 3 are used to vertically insert the needles 8. In the middle above the working frame 1 and located between the feeding turntable 2 and the second push cylinder 9, a first push cylinder 4 is installed. A lifting frame 5 is arranged at the top of the first push cylinder 4, and a rotating seat 6 is installed in the middle of the front end of the lifting frame 5. A double chuck 7 is installed at the front end of the rotating seat 6. The double chuck 7 is composed of two chucks that are the same as the single chuck 10 and are arranged vertically and oppositely. The needles 8 are clamped at the ends of the double chuck 7. The needles 8 inserted on the receiving sockets 3 are conveyed to the station of the double chuck 7 by the feeding turntable 2. The needles 8 are clamped by the double chuck 7. With the upward movement of the first push cylinder 4 and the horizontal flipping of the rotating seat 6, the tips of the needles 8 are vertically transferred downward to the station of the single chuck 10. The second push cylinder 9 is used to push the single chuck 10 to clamp the needles 8. After clamping, the needles 8 are directly above the immersion oil tank 12 and perpendicular to the center of the immersion oil tank 12. The third push cylinder 11 drives the immersion oil tank 12 to move upward, so that the needles 8 are inserted into the immersion oil tank 12, facilitating subsequent oil immersion of the needles 8 and removal of excess oil; The push-pull mechanism 13 includes a driving gear 1301 installed in the middle of the lower part inside the immersion oil tank 12. On both sides below the driving gear 1301, there are meshed driven gears 1302, and on the other side of the driven gear 1302, there is an integrated screw rod 1303. In the middle of the screw rod 1303, there is a threaded connection with a sliding block 1304. On both sides in the middle of the sliding block 1304, there are fixed guide rods 1306. And the driving gear 1301 is rotationally connected to the screw rod 1303 through the driven gear 1302. The sliding block 1304 is slidably connected to the inner wall of the immersion oil tank 12 through the screw rod 1303 and the guide rods 1306. The guide rods 1306 can limit the movement of the sliding block 1304. And above the sliding block 1304, there is a rotationally connected connecting rod 1305. At the top of the connecting rod 1305, there is a rotationally installed first piston disc 1307. And outside the first piston disc 1307, there is a first piston cylinder 1308. The first piston disc 1307 is slidably connected to the first piston cylinder 1308 through the sliding block 1304 and the connecting rod 1305. By the driving gear 1301 driven by a reduction motor, the driven gear 1302 and the screw rod 1303 can be driven to rotate forward and backward, so that the sliding block 1304 slides left and right on the screw rod 1303. When the sliding block 1304 moves left and right, the connecting rod 1305 will cause the first piston disc 1307 to slide up and down in the first piston cylinder 1308, thereby providing power for subsequent clamping vibration and oil replacement; Above the left and right two groups of first piston cylinders 1308, there are both connected and installed solenoid valves 1309. And above the solenoid valves 1309, there is a connection with a mounting joint 1310. On one side above the mounting joint 1310, there is a connection with a second piston cylinder 1311. And at the front end inside the second piston cylinder 1311, there is a piston push rod 1312. At the front end of the piston push rod 1312, there is a pressure head 1313. And in the middle of the inner side of the pressure head 1313, there is an ultrasonic vibration head 1315. Behind the second piston cylinder 1311, there is a connection with a pressure relief valve 1314. And the pressure relief valve 1314, the second piston cylinder 1311, the mounting joint 1310 and the solenoid valve 1309 are connected and communicated. And the solenoid valve 1309 is connected and communicated with the first piston cylinder 1308. Above one side of the outside of the first piston cylinder 1308, there is a connection with an intake valve 15; Through the solenoid valve 1309, which opens when the first piston disk 1307 moves upward within the first piston cylinder 1308. At this time, the air inside the first piston cylinder 1308 will be squeezed upward, and the air pressure will push the piston push rod 1312 inside the second piston cylinder 1311 forward along the mounting joint 1310, causing the piston push rod 1312 to push the pressure head 1313 forward. At this time, the two symmetrically arranged pressure heads 1313 will clamp the mounting end part of the needle 8 inserted into the oil immersion tank 12. After clamping, the solenoid valve 1309 closes to prevent the second piston cylinder 1311 from leaking air. Through the ultrasonic vibration head 1315 inside the pressure head 1313, after the needle 8 is immersed in oil, the pressure head 1313 can be used to perform high-frequency vibration on the needle 8, causing vibration separation on the surface of the needle 8. Through the pressure relief valve 1314, the excess pressure received by the second piston cylinder 1311 can be discharged to prevent the pressure head 1313 from exerting excessive pressure and damaging the needle 8. By opening the air inlet valve 15 into the first piston cylinder 1308, the first piston cylinder 1308 can be re-inflated when the first piston disk 1307 moves downward; The clamping of the needle 8 by the pressure head 1313 finally achieved by the upward movement of the first piston disk 1307, and the high-frequency vibration of the ultrasonic vibration head 1315 inside the pressure head 1313 on the needle 8 after the needle 8 is immersed in oil, can cause the excess oil on the surface of the needle 8 to vibrate rapidly and separate from the needle 8. Moreover, under the action of the high-frequency mechanical force, the adhesion between the oil and the needle 8 and the internal cohesion of the oil itself are destroyed, making it easier for the oil to separate into small oil droplets from the surface of the needle 8, thereby improving the thoroughness of oil removal.
[0023] To solve the problem that the exposed oil immersion tank is prone to pollution and deterioration after long-term use, as Figure 4 、 Figure 5 、 Figure 9 and Figure 10 shown: An oil immersion mechanism 14 is provided in the middle of the inner side of the oil immersion tank 12. The oil immersion mechanism 14 includes a third piston cylinder 1401 connected to the outer side of the middle of the first piston cylinder 1308. A gas guide pipe 1402 is connected to the lower side of one side of the third piston cylinder 1401. The other side of the gas guide pipe 1402 is connected to a fourth piston cylinder 1403. A second piston disk 1404 is provided below the inside of the fourth piston cylinder 1403. The fourth piston cylinder 1403, the gas guide pipe 1402, and the third piston cylinder 1401 are connected and communicate with each other. Through the third piston cylinder 1401, a piston piece is provided on the side close to the first piston cylinder 1308 inside it, which can move toward the fourth piston cylinder 1403 side when the first piston disk 1307 moves upward to transmit air pressure, causing the gas to be pressed into the fourth piston cylinder 1403 through the gas guide pipe 1402. At this time, the second piston disk 1404 inside the fourth piston cylinder 1403 moves upward under the air pressure; Above the middle of the air duct 1402, an air distribution pipe 1405 is connected. On one side above the air distribution pipe 1405, an air charging balloon 1406 is arranged. The air distribution pipe 1405 is communicated with the air duct 1402. Through the air distribution pipe 1405, part of the gas in the air duct 1402 can be filled into the air charging balloon 1406, so that the hollow annular air charging balloon 1406 expands to wrap and squeeze the needle 8, and seal the needle 8 and the top of the fourth piston cylinder 1403 to prevent the oil from splashing when soaking in oil. On the outer side of the upper part of the fourth piston cylinder 1403, a liquid inlet valve 1407 is installed. Above the liquid inlet valve 1407, a liquid guide pipe 1408 is connected. At the top of the liquid guide pipe 1408, an oil storage cavity 1409 is arranged. On the outer side of the lower part of the fourth piston cylinder 1403, an oil outlet valve 1410 is installed. Below the oil outlet valve 1410, a lower oil pipe 1411 is connected. Below the lower oil pipe 1411, an oil collection cavity 1412 is connected. Through the liquid inlet valve 1407, it can be opened towards the inside of the fourth piston cylinder 1403 under pressure when the second piston disc 1404 moves upward and squeezes, so that the silicone oil in the oil storage cavity 1409 flows into the fourth piston cylinder 1403 along the liquid guide pipe 1408, so as to soak the needle 8. After the oil soaking is completed, when the first piston disc 1307 moves downward, the air flow will flow in the reverse direction. At this time, the liquid inlet valve 1407 will close, and the second piston disc 1404 and the filled oil will move downward. Through the outward-opening oil outlet valve 1410 and the lower oil pipe 1411, the oil after oil soaking can be circulated and recovered into the oil collection cavity 1412. By moving the first piston disc 1307 up and down, the gas in the third piston cylinder 1401 moves left and right to drive the second piston disc 1404 to move up and down, so that the fourth piston cylinder 1403 can finally realize the reciprocating process of filling and discharging oil, so that the automatic replacement of oil can be realized when soaking in oil, avoiding the problem that pollutants such as impurities and metal chips will gradually mix into the oil during the oil soaking process and affect the subsequent use of the needle 8. At the same time, the replaced oil can immerse each needle 8 in new oil, avoiding the problem of deterioration due to the long-term use of a large oil soaking tank and the oil not being used up.
[0024] Working principle: When using this fully automatic insulin built-in needle assembly device, first, the needle inserted on the receiving socket 3 is conveyed to the station of the double chuck 7 through the feeding turntable 2. Then, the double chuck 7 is used to clamp the needle 8. With the upward movement of the first pushing cylinder 4 and the horizontal flipping of the rotating seat 6, the tip of the needle 8 is vertically transferred downward to the station of the single chuck 10. Then, the second pushing cylinder 9 is used to push the single chuck 10 to clamp the needle 8. Then, the third pushing cylinder 11 drives the oil soaking tank 12 to move upward, so that the needle 8 is inserted into the oil soaking tank 12. At this time, the driving gear 1301 driven by the reduction motor can drive the driven gear 1302 and the screw rod 1303 to rotate forward, so that the sliding block 1304 slides leftward on the screw rod 1303. When the sliding block 1304 moves left and right, the connecting rotating rod 1305 will cause the first piston disc 1307 to slide upward in the first piston cylinder 1308. Subsequently, by opening the solenoid valve 1309, the air in the first piston cylinder 1308 will be squeezed upward, and the air pressure will squeeze the piston push rod 1312 in the second piston cylinder 1311 forward along the mounting joint 1310, so that the piston push rod 1312 pushes the pressure head 1313 forward. Subsequently, the pressure heads 1313 on both sides clamp the mounting end part of the needle 8 inserted into the oil immersion tank 12. After clamping, the solenoid valve 1309 is closed. At this time, through the piston piece in the third piston cylinder 1401, the air pressure can be transmitted to the side of the fourth piston cylinder 1403, so that the gas is pressed into the fourth piston cylinder 1403 by the air duct 1402. Then, the second piston disc 1404 in the fourth piston cylinder 1403 moves upward under the air pressure. Through the branch air duct 1405, part of the gas in the air duct 1402 can be filled into the air filling bag 1406, so that the hollow annular air filling bag 1406 expands to wrap and squeeze the needle 8. At this time, the liquid inlet valve 1407 can be opened when the second piston disc 1404 moves upward, so that the silicone oil in the oil storage cavity 1409 flows into the fourth piston cylinder 1403 along the liquid guide pipe 1408 to perform oil immersion treatment on the needle 8; After the oil immersion is completed, the driving gear 1301 rotates reversely to make the first piston disc 1307 move downward. At this time, the liquid inlet valve 1407 is closed, and the second piston disc 1404 and the filled oil move downward. Then, through the oil outlet valve 1410 and the lower oil pipe 1411, the oil after oil immersion is circulated and recovered into the oil collection cavity 1412. Subsequently, through the ultrasonic vibrator head 1315, the pressure head 1313 is used to perform high-frequency vibration on the needle 8, so that the surface of the needle 8 vibrates and separates. Finally, by opening the solenoid valve 1309 and the air inlet valve 15, the pressure head 1313 can be depressurized and the first piston cylinder 1308 can be re-inflated.
