Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an automatic feeding device. Background Art

[0002] A syringe is a common medical tool. In the medical system, disposable syringes have been widely used. The reason is that when using a disposable syringe, no disinfection treatment is required. The user only needs to tear open the outer package, which has the advantages of convenient use, safety and hygiene. Syringes can not only be used as medical tools, but also for pharmaceutical research and development. For example, some scientific instruments in chromatography inject through a rubber diaphragm. Therefore, the market demand for syringes is huge.

[0003] A syringe includes a barrel. A cavity is provided inside the barrel for containing the liquid to be injected. A finger hanging part is provided on the outer edge of the upper part of the barrel, which is convenient for fixing the barrel with fingers during injection.

[0004] During the assembly process of the syringe, the feeding of the barrel is involved. In order to improve the assembly efficiency, the equipment must have the ability to batch-feed the barrels. Therefore, it is necessary to design an automatic feeding device to solve the above problems. Summary of the Invention

[0005] To overcome the above disadvantages, the purpose of the present invention is to provide an automatic feeding device that automatically batch-feeds barrels and improves the processing efficiency of subsequent syringe assembly.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: an automatic feeding device, including a frame, including a feeding mechanism, a material taking mechanism and a material taking fixture located on the frame; the feeding mechanism includes a feeding tray and a receiving member corresponding to the position of the feeding tray. The feeding tray rotates to sequentially move the barrels to the receiving member within the material taking range of the material taking mechanism. The material taking mechanism includes a fixing device and a material taking lifting assembly for driving the fixing device to move. The barrels are batch-placed in the material taking fixture located below the material taking mechanism through the material taking mechanism, and the material taking fixture clamps and fixes a plurality of barrels located inside it.

[0007] Preferably, a plurality of first card slots for accommodating barrels are provided on the feeding tray, and a plurality of second card slots for receiving the barrels located in the first card slots are provided on the receiving member. Each groove wall of the second card slot is in a straight tooth shape, and each groove wall of the first card slot is in an inclined tooth shape. The groove wall of the first card slot inclines towards the rotation direction of the feeding tray. When the feeding tray rotates, it is convenient to sequentially convey the materials to be conveyed to the receiving member and successively snap them into the second card slots.

[0008] Preferably, the receiving member moves in a direction close to or away from the loading tray, and the movement trajectory of the receiving member is a straight line. The distance between any two adjacent first card slots on the loading tray is equal to the distance between any two second card slots of the receiving member, which can ensure that each material to be conveyed on the first card slot is successively and orderly clamped into the second card slot.

[0009] Preferably, the loading mechanism further includes a translation component and a telescopic component. The translation component includes a translation motor, a sliding seat, and a first slide rail arranged along the width direction of the frame. The receiving member is connected to the lead screw through the sliding seat. The translation motor drives the lead screw to rotate, so that the receiving member moves back and forth along the first slide rail. The telescopic component includes a telescopic cylinder and a second slide rail located on the sliding seat. The telescopic cylinder drives the receiving member to move in a direction close to or away from the material taking mechanism. The translation component drives the receiving member to move horizontally along the width direction of the frame, so that the receiving member moves in a straight line. On the one hand, it enables the syringes to be batch-fed into the second card slots on the receiving member in sequence. On the other hand, it can move the receiving member with the syringes onto the pushing component for subsequent feeding; the position distance between the receiving member and the loading tray is adjusted through the telescopic component, and the position distance between the receiving member and the loading tray is adjusted, and at the same time, it is ensured that when the receiving member is reset, there will be no collision with the loading tray.

[0010] Preferably, the loading tray includes at least two disk bodies arranged in parallel and a loading track. The two disk bodies are concentrically arranged, and the first card slots of the two disk bodies are arranged opposite to each other. A feeding component is also arranged at a position corresponding to the loading tray. The feeding component includes a fixed feeding block one and a feeding block two. The feeding block one is located at the edge of the loading tray close to the receiving member, and the feeding block two is located on the side of the loading tray close to the loading track. A squeezing groove body for the syringe to pass through is formed between the feeding surface one on the feeding block one and the feeding surface two on the feeding block two. By arranging at least two disk bodies, the two ends of the syringe are respectively clamped into the first card slots of the two disk bodies, and two upper and lower clamping points are formed for the syringe to ensure the smoothness of the material conveying process.

[0011] Preferably, it further includes a pushing component and a material blocking component. The pushing component includes a pushing cylinder and a pushing plate located below the receiving member. The piston rod of the pushing cylinder extends to drive the pushing plate to move upward, pushing the syringe out of the second card slot on the receiving member. The material blocking component includes a material blocking cylinder and a material blocking plate arranged close to the receiving member. When the syringe in the second card slot on the receiving member is pushed upward by the pushing plate in batches, the material blocking plate is located on the side close to the second card slot on the receiving member, which can effectively prevent the material from falling off the second card slot when it is lifted.

[0012] Preferably, the material taking and lifting assembly includes a lifting guide rod, a lifting bracket located on the frame and reciprocating along the length direction of the frame, and a lifting cylinder. The lifting cylinder drives the fixing device to move up and down along the lifting guide rod. The fixing device includes a fixing plate, a first fixing component located on the fixing plate, and second fixing components located at both ends of the fixing plate in the length direction. The second fixing component includes a pneumatic gripper telescopic plate and two telescopic plates arranged in parallel along the length direction of the fixing plate. The pneumatic gripper drives the two telescopic rods to move relatively towards or away from the hooking part on the syringe barrel, and clamps and fixes the lower surface of the hooking part of the syringe barrel through the telescopic plates, ensuring that the syringe barrel does not fall during the batch transportation of the syringe barrel.

[0013] Preferably, the first fixing component includes a plurality of fixing rods and a first spring. Each fixing rod is movably connected to the fixing plate through a fixing ring. A convex part matching the inner diameter of the cavity of the syringe barrel is arranged at the bottom of the fixing rod. The first spring is sleeved on the fixing rod, with one end abutted against the bottom of the fixing ring and the other end abutted against the upper surface of the positioning ring on the fixing rod. When the first spring is in a compressed state, the fixing rod moves up and down along the fixing ring. By providing the convex part 3213, on the one hand, when clamping the syringe barrel 4, the convex part 3213 first inserts into the cavity of the syringe barrel 4 to position the syringe barrel 4, so that the first fixing component 321 and the second fixing component 323 can clamp the syringe barrel 4; on the other hand, by inserting the convex part 3213 into the cavity 41, during the process of clamping and transferring the syringe barrel 4, it can play a role in fixing the syringe barrel 4 and prevent the syringe barrel 4 from shaking during the movement.

[0014] Preferably, the material taking fixture includes a vertical plate and a driving device. A plurality of material placing grooves for placing the syringe barrels are formed on the vertical plate. The driving device includes a material pushing plate, a moving plate, and a driving member for driving the moving plate to move along the length direction of the vertical plate. The material pushing plate is located in the material placing groove and can reciprocate along the length direction of the material placing groove. A plurality of material pushing pins corresponding to the positions of the material pushing plate are arranged on the moving plate. When the driving member drives the moving plate to move, the material pushing pins push the corresponding material pushing plates to move in the direction of clamping or loosening the syringe barrel.

[0015] Preferably, the material pushing plate is connected to a fixing block in the moving plate through a moving rod. A part of the moving rod between the fixing block and the material pushing plate is covered with a second spring. The material pushing plate and a side wall in the material placing groove form a clamping cavity for clamping the syringe barrel. The material pushing plate reciprocates in the material placing groove to clamp and loosen the syringe barrel, and at the same time, the second spring provides power for the reset of the material pushing plate.

[0016] Advantages of the present invention:

[0017] Through the mutual cooperation of the feeding mechanism, the material taking mechanism and the material taking fixture, the feeding tray in the feeding mechanism rotates to transfer the syringe barrels on the feeding tray to the receiving member, realizing the rapid and neat arrangement of the syringe barrels, which is convenient for the subsequent material taking mechanism to perform batch feeding; the material taking lifting assembly in the material taking mechanism transfers the fixing device to above the receiving member, and by setting the fixing device, the neatly arranged syringe barrels on the receiving member are clamped and taken; after the material taking mechanism batch-clamps the syringe barrels, the syringe barrels are transferred to the material taking fixture, and the syringe barrels placed therein are clamped and positioned by the material taking fixture, which is convenient for the syringe barrels to enter the next assembly process in batches and improves the processing efficiency of the subsequent syringe assembly.

Detailed implementation manners

[0030] The following elaborates on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0031] See the attached Figures 1 to 11 As shown, an automatic loading device in this embodiment includes a frame 1, and a loading mechanism 2, a material picking mechanism 3, and a material picking fixture 5 located on the frame 1; the loading mechanism 2 includes a loading tray 21 and a receiver 23 corresponding to the position of the loading tray 21. The loading tray 21 rotates to sequentially move the syringe 4 onto the receiver 23 within the material picking range of the material picking mechanism 3. The loading tray 21 can be driven by a loading motor (not shown in the figure), and the loading motor is arranged at a certain distance from the loading tray 21. When the loading motor drives the loading tray 21 to rotate, the syringes in the first card slots 22 on the loading tray 21 sequentially enter the second card slots 24 on the linearly moving receiver 23, realizing the rapid and neat arrangement of the syringes, which is convenient for subsequent material picking at the next station;

[0032] The material taking mechanism 3 includes a fixing device 32 and a material taking lifting assembly 31 for driving the fixing device 32 to move. The syringe barrels 4 are placed in batches in the material taking fixture 5 located below the material taking mechanism 3 through the material taking mechanism 3. The fixing device 32 is used for clamping and fixing the syringe barrels 4 in batches, and the material taking lifting assembly 31 is used for driving the fixing device 32 to move up and down to pick up the syringe barrels on the receiving part 23; the material taking fixture 5 clamps and fixes several syringe barrels 4 located inside it.

[0033] The feeding motor arranged at the bottom of the frame 1 drives the feeding disk 21 to rotate, and the syringe barrels are fed onto the feeding turntable 21 in sequence through the feeding track 212. When the feeding disk 21 rotates (see Figure 2 the indicated rotation direction of the feeding disk in the figure), the receiving part 23 moves away from the feeding disk 21. Since the positions of the feeding disk 21 and the receiving part 23 correspond to each other, the syringe barrels will be sequentially moved onto the receiving part 23 under the rotation of the feeding disk 21. The material taking mechanism 3 moves along the moving slide rail on the frame 1 to above the receiving part, picks up the syringe barrels on the receiving part 23 through the fixing device 32, and resets after picking up the materials. At this time, the reset material taking mechanism 3 corresponds to the position of the material taking fixture 5. The piston rod of the material taking lifting assembly 31 extends to drive the clamped syringe barrels to move downward and put them into the material taking fixture 5, realizing the automatic feeding of the syringe barrels.

[0034] See the appendix Figures 2 to 3 , a plurality of first card slots 22 for accommodating the syringe barrels 4 are formed on the feeding disk 21, and a plurality of second card slots 24 for receiving the syringe barrels 4 located in the first card slots 22 are formed on the receiving part 23. Each groove wall of the second card slot 24 is in a straight tooth shape, and each groove wall of the first card slot 22 is in an inclined tooth shape. The groove wall of the first card slot 22 inclines towards the rotation direction of the feeding disk 21. When the feeding disk 21 rotates, it is convenient to convey the materials to be transported one by one to the receiving part 23 and sequentially snap them into the second card slots 24, and make the syringe barrels 4 arranged neatly.

[0035] The receiving part 23 moves towards or away from the feeding disk 21, and the moving track of the receiving part 23 is a straight line. The distance between any two adjacent first card slots 22 on the feeding disk 21 is equal to the distance between any two second card slots 24 on the receiving part 23, which can ensure that each of the syringe barrels to be transported on the first card slot 22 is snapped into the second card slot 24 one by one and orderly.

[0036] The feeding mechanism 2 further includes a translation component 25 and a telescopic component 26. The translation component 25 includes a translation motor 251, a sliding seat 253, and a first slide rail 252 arranged along the width direction of the frame 1. The receiving member 23 is connected to the lead screw 254 through the sliding seat 253. The translation motor 251 drives the lead screw 254 to rotate, so that the receiving member 23 moves back and forth along the first slide rail 252. The telescopic component 26 includes a telescopic cylinder 261 and a second slide rail 262 located on the sliding seat 253. The telescopic cylinder 261 drives the receiving member 23 to move in a direction close to or away from the material taking mechanism 3. The translation component 25 drives the receiving member 23 to move horizontally along the width direction of the frame 1, so that the receiving member 23 makes a linear motion. On the one hand, it enables the syringes 4 to be batch-fed into the second card slots 24 on the receiving member 23 in sequence. On the other hand, it can move the receiving member 23 loaded with the syringes 4 onto the pushing component 27 for subsequent feeding. The telescopic component 26 adjusts the position distance between the receiving member 23 and the feeding tray 21, coordinates the position distance between the receiving member 23 and the feeding tray 21, and also ensures that there is no collision between the receiving member 23 and the feeding tray 21 when the receiving member 23 resets.

[0037] The feeding tray 21 includes at least two disk bodies 211 arranged in parallel with each other and a feeding track 212. The two disk bodies 211 are concentrically arranged, and the first card slots 22 of the two disk bodies 211 are arranged opposite to each other. A dialing component 29 is also arranged at a position corresponding to the feeding tray 21. The dialing component 29 includes a fixedly arranged first dialing block 291 and a second dialing block 292. The first dialing block 291 is located at the edge of the feeding tray 21 close to the receiving member 23, and the second dialing block 292 is located on one side of the feeding tray 21 close to the feeding track 212. A squeezing chute body for the syringe 4 to pass through is formed between the first dialing surface 293 on the first dialing block 291 and the second dialing surface 294 on the second dialing block 292. By arranging at least two disk bodies 211, the two ends of the syringe 4 are respectively clamped into the first card slots 22 of the two disk bodies 211, and by forming two upper and lower clamping points for the syringe 4, the smoothness of the material conveying process is ensured.

[0038] It further includes a pushing component 27 and a material blocking component 28. The pushing component 27 includes a pushing cylinder 271 and a pushing plate 272 located below the receiving part 23. When the piston rod of the pushing cylinder 271 extends, it drives the pushing plate 272 to move upward, pushing the syringe 4 out of the second card slot 24 on the receiving part 23. The material blocking component includes a material blocking cylinder 281 and a material blocking plate 282 disposed close to the receiving part 23. The syringes 4 located in the second card slot 24 on the receiving part 23 are pushed upward in batches by the pushing plate 272, facilitating subsequent processing. During the process of the syringes 4 being pushed upward out of the receiving part 23, the material blocking plate 282 is located on one side close to the second card slot 24 on the receiving part 23, effectively preventing the materials from falling off from the second card slot 24 when being lifted.

[0039] The working principle of the feeding mechanism: The syringes 4 are sequentially conveyed to the first card slots 22 on the feeding tray 21 through the feeding track 212. As the receiving part 23 moves forward driven by the translation component 25 and the feeding motor drives the rotation of the feeding tray 21, the syringes 4 located in each first card slot 22 are sequentially conveyed to the second card slots 24 of the receiving part 23. After the second card slots 24 on the receiving part 23 are all filled with syringes 4, the receiving part 23 moves to the position of the pushing component 27. The pushing plate 282 pushes each syringe 4 upward by a certain height under the action of the pushing cylinder 271, facilitating the removal of the syringes 4. Subsequently, the telescopic component 28 starts to work. The piston rod of the telescopic cylinder 261 retracts, driving the receiving part 23 to retreat. The receiving part 23 returns to a position close to the feeding tray 21 under the action of the translation component 25. Since the receiving part 23 has retreated driven by the telescopic cylinder 261, it can avoid the collision of the receiving part 4 against the materials located on the feeding tray 3 when returning to the starting point. After the receiving part 23 returns to the starting point, the telescopic cylinder 261 pushes the receiving part 23 to move towards the side close to the feeding tray 21 again and receives the syringes transmitted from the feeding tray 21 once again. In this way, cyclic operation realizes the batch alignment of the syringes, facilitating the subsequent feeding of the syringes 4.

[0040] See the appendix Figures 4 to 8 As shown in the figure, the material taking and lifting component 31 includes a lifting guide rod 312, a lifting bracket 313 located on the frame 1 and reciprocating along the length direction of the frame 1, and a lifting cylinder 311. The lifting cylinder 311 drives the fixing device 32 to move up and down along the lifting guide rod 312, facilitating the stable up and down movement of the fixing device 32 to realize the material taking of the syringe 4.

[0041] The fixing device 32 includes a fixing plate 322, a first fixing component 321 located on the fixing plate 322, and second fixing components 323 located at both ends in the length direction of the fixing plate 322. The second fixing component 323 includes a pneumatic gripper 3231 and two telescopic plates 3232 arranged in parallel along the length direction of the fixing plate 322. The pneumatic gripper 3231 drives the two telescopic rods to move relatively towards or away from the hooking portion 42 on the syringe barrel 4, and clamps and fixes the lower surface of the hooking portion 42 of the syringe barrel 4 through the telescopic plate 3232, ensuring that the syringe barrel 4 does not fall during the batch transportation of the syringe barrel 4.

[0042] The first fixing component 321 includes a plurality of fixing rods 3211 and a first spring 3214. Each fixing rod 3211 is movably connected to the fixing plate 322 through a fixing ring 3212. A retaining piece that hooks on the top of the fixing ring 3212 is provided at the top of the fixing rod 3211, so that the fixing rod 3211 does not fall when moving up and down within the fixing ring 3212;

[0043] See Appendix Figures 6 to 7 , a protruding portion 3213 that matches the inner diameter of the cavity 41 of the syringe barrel 4 is provided at the bottom of the fixing rod 3211. By providing the protruding portion 3213, on the one hand, when the syringe barrel 4 is clamped and taken, the protruding portion 3213 first inserts into the cavity of the syringe barrel 4 to position the syringe barrel 4, so that the first fixing component 321 and the second fixing component 323 can clamp and take the syringe barrel 4; on the other hand, by inserting the protruding portion 3213 into the cavity 41, during the process of clamping and transferring the syringe barrel 4, the syringe barrel 4 can be fixed to prevent the syringe barrel 4 from shaking during movement;

[0044] The first spring 3214 is sleeved on the fixing rod 3211, and one end abuts against the bottom of the fixing ring 3212, and the other end abuts against the upper surface of the positioning ring 3215 on the fixing rod 3211. When the first spring 3214 is in a compressed state, that is, at this time the material taking and lifting component 31 drives the fixing device 32 to move downward, the protruding portion 3213 at the bottom of the fixing rod 3211 inserts into the cavity 41 of the syringe barrel 4, and the fixing rod 3211 moves upward along the fixing ring 3212. When the hooking portion 42 of the syringe barrel 4 is higher than the telescopic plate 3232 on the second fixing component 323, the pneumatic gripper 3231 drives the telescopic plate 3232 to move towards the syringe barrel 4 to clamp the syringe barrel 4. At this time, the upper surface of the telescopic plate 3232 abuts against the lower end surface of the hooking portion 42.

[0045] The working principle of the material taking mechanism 3: The piston rod of the lifting cylinder 311 extends to drive the fixing device 2 to move downward along the lifting guide rod 312. When the protruding portion 3213 of the fixing rod 3211 is inserted into the cavity 41 of the syringe 4, the fixing rod 3211 and the syringe 4 move upward relative to the fixing member 3211. When the height of the hooking portion 42 on the syringe 4 is higher than the height of the telescopic plate 3232, the telescopic plate 3232 moves in the direction close to the fixing rod 3211 driven by the pneumatic gripper 3231, so that the upper end surface of the telescopic plate 3232 abuts against the lower surface of the hooking portion 42 of the syringe 4. At this time, the syringe 4 on the receiving member 23 is completely clamped, and the lifting cylinder 311 drives the fixing device 32 to move upward, moving the syringe 4 to the subsequent material taking fixture.

[0046] See the appendix Figures 10 to 11 As shown, the material taking fixture 5 includes a vertical plate 52 and a driving device 51. A plurality of material placing grooves 54 for placing the syringe 4 are formed on the vertical plate 52. The driving device 51 includes a material pushing plate 512, a moving plate 515, and a driving member 511 for driving the moving plate 515 to move along the length direction of the vertical plate 52. The material pushing plate 512 is located in the material placing groove 54 and can move back and forth along the length direction of the material placing groove 54. When the piston rod of the driving member 511 extends, a larger space for the syringe 4 to be placed is formed between the material pushing plate 512 and one side of the material placing groove 54. When the piston rod of the driving member 511 retracts, the material pushing plate 512 moves in the direction of the syringe 4, reducing the space in the material placing groove 54 and clamping the syringe 4 in the material placing groove 54. And two adjacent material pushing plates 512 are located at different heights, effectively reducing the space occupied by the material pushing plate 512 on the vertical plate and enabling the material taking fixture to clamp more syringes 4 at one time;

[0047] A plurality of dial pins 513 corresponding to the positions of the material pushing plates 512 are arranged on the moving plate 515. When the driving member 511 drives the moving plate 515 to move, the dial pins 513 push the corresponding material pushing plates 512 to move in the direction of clamping or loosening the syringe 4. The material pushing plate 512 is connected to a fixed block 518 in the moving plate 515 through a moving rod 516. A second spring 514 is wrapped around the part of the moving rod 516 between the fixed block 518 and the material pushing plate 512. The material pushing plate 512 and one side wall in the material placing groove 54 form a clamping cavity for clamping the syringe 4. The material pushing plate 512 moves back and forth in the material placing groove 54 to realize the clamping and loosening of the syringe 4, and at the same time, the second spring 514 provides power for the reset of the material pushing plate 512.

[0048] The working principle of the material taking fixture: Initially, the telescopic shaft of the driving member 511 extends, driving the moving plate 515 to move linearly, and then driving the pin 513 thereon to move synchronously. During the movement of the pin 513, it abuts against the material pushing plate 512, pushing the material pushing plate 512 to move towards the side away from the syringe barrel 4. At this time, the movement trajectory of the material pushing plate 512 is a straight line. At this time, a space for placing the syringe barrel 4 is formed between the material pushing plate 512 and the side wall of the material placing groove 54, and the second spring 514 is in a compressed state at this time. The distance between the material pushing plate 512 and the corresponding side wall becomes larger, and several syringe barrels 4 are placed in the placing groove 54 under the drive of the material taking mechanism. Then the telescopic shaft of the driving member 511 retracts, driving the moving plate 515 to move linearly in the reverse direction, and then driving the pin 513 to move synchronously. The pin 513 moves to be separated from the material pushing plate 512, and the material pushing plate 512 quickly moves linearly towards the syringe barrel 4 under the action of the compressed second spring 514, clamping the syringe barrel 4 between the corresponding side wall and the material pushing plate 512, realizing the clamping of the syringe barrel 4.
