Description

Technical Field

[0001] The utility model relates to a medical syringe needle directional feeding device. Background Art

[0002] Medical needles are indispensable medical devices in modern medicine. The needles inserted into the human body vary in various aspects such as length, thickness, etc., which leads to a wide variety of medical needles. Moreover, medical needles have high requirements for safety and hygiene, and require professional dust-free and sterile packaging and assembly, which greatly improves the production requirements for manufacturers. During the production process, feeding and assembling syringe needles with different diameters and specifications is a complex operation process, and the existing equipment cannot meet the usage requirements during the production process.

[0003] In the prior art, when the upper needle device feeds materials, the syringe needles are all stacked at the feeding port. When feeding, if the lifting feeding method is adopted, the situations of disordered needles and skipped needles will inevitably occur, and the feeding difficulty is great. Summary of the Invention

[0004] The purpose of the utility model is to solve the above-mentioned deficiencies of the prior art, and provide a medical syringe needle directional feeding device. What this application solves is that when feeding materials, the syringe needles are all stacked at the feeding port, and when the lifting feeding method is adopted, the situations of disordered needles and skipped needles will occur, and the feeding difficulty is great.

[0005] A medical syringe needle directional feeding device includes a bracket. A material supporting seat is arranged on the bracket. A material placing groove is formed on the upper surface of the material supporting seat. A guiding through hole is formed at the bottom of the material placing groove. A thimble plate that penetrates through the guiding through hole and can reciprocate up and down is arranged below the material supporting seat. A baffle is connected to the side wall of the material supporting seat. Both side walls of the material placing groove have a first inclined surface and a second inclined surface that extend obliquely upward from bottom to top, and the first inclined surface and the second inclined surface are connected to each other. The first inclined surface and the second inclined surface are symmetrically arranged with the guiding through hole as the center. The inclination degree of the first inclined surface is greater than that of the second inclined surface. Guide blocks connected to the side wall of the baffle are arranged above the joints of the first inclined surface and the second inclined surface respectively.

[0006] The first inclined surface and the second inclined surface can both guide and support the syringe needles, and control the running trajectories of all the syringe needles to run from top to bottom along the second inclined surface and the first inclined surface to the bottom of the material discharging groove. The syringe needles are stacked inside the material discharging groove. Each time the ejector plate rises, it can drive one syringe needle to rise, realizing intelligent automatic feeding. The ejector plate makes reciprocating up and down movements inside the guiding through hole. The included angle between the two first inclined surfaces is smaller than the included angle between the two second inclined surfaces. Using different included angles can control the running speed of the syringe needles differently, and at the same time, make the syringe needles inside the material discharging groove move closer to the center. The space inside the material discharging groove is divided into two parts. One part is the area waiting for feeding, where the syringe needles wait for the ejector plate to lift them for feeding. The other part is the preparation area, where the syringe needles in the preparation area wait to enter the area waiting for feeding. This makes the number of stacked syringe needles in the area waiting for feeding limited and less than the number of stacked syringe needles in the preparation area, avoiding the phenomenon of the syringe needles being in a disorderly state due to a large number of stacked syringe needles, facilitating the ejector plate to lift the syringe needles one by one, ensuring the requirement that the ejector plate can only lift one syringe needle during a single operation, realizing continuous cyclic feeding, meeting the production needs, and effectively avoiding needle jamming and needle skipping.

[0007] The rotatable and adjustable baffle can adjust the distance between the guiding block and the side wall of the material discharging groove, meeting the feeding requirements of syringe needles with different diameters. During the feeding process, a small number of syringe needles are stacked in the area waiting for feeding, and most of the syringe needles are stacked in the preparation area, which can effectively prevent too many syringe needles from being stacked in the area waiting for feeding and causing the syringe needles to be disorderly during the feeding process. In addition, the adjustment function of the guiding block can better adapt to the feeding of syringe needles with different lengths and diameters, achieving the effects of convenient feeding and simple adjustment, and greatly improving the practicability.

[0008] Furthermore, optical fiber mounting plates for installing optical fiber detection devices are provided at both ends of the material supporting seat.

[0009] In this application, the optical fiber detection device is used to detect whether the syringe needle is ejected by the ejector plate. The optical fiber detection device can convert the information detected during the operation of the optical fiber into regular electrical signals for output. It has the characteristics of being sensitive, small, easy to install, strong adaptability, and low cost, meeting the needs of large-scale or a large number of detections. After the optical fiber detection device detects that there is a syringe needle on the ejector plate, the grasping component runs through the stroke slot rail to the upper part of the ejector plate to grasp the syringe needle, and then continues to run to the next station. When the detection data of the optical fiber detection device shows that there is no syringe needle on the ejector plate, the grasping component does not perform the grasping operation until the optical fiber detection device detects that there is a syringe needle on the ejector plate and then performs the grasping operation, which can effectively avoid the occurrence of ineffective strokes, ensure the operation efficiency and accuracy, and at the same time ensure the accuracy of the production data automatically generated after the equipment runs and the production volume after the equipment runs.

[0010] Further, a detection notch is provided on the upper surface of the thimble plate, which penetrates the optical fiber emitted by the optical fiber detection device.

[0011] In this application, the position of the optical fiber emitted by the optical fiber detection device remains unchanged. During the upward movement of the thimble plate, if there is a syringe needle on the thimble plate, the data information of the optical fiber will change during the upward movement of the thimble plate. If there is no syringe needle on the thimble plate, the optical fiber will not generate data information change during the upward movement of the thimble plate. Due to the excellent detection effect of the optical fiber detection device and the perception effect of small changes, it can effectively meet the detection requirements, improve the accuracy of the detection process, and cooperate with the grasping component to achieve 100% effective feeding and grasping, avoiding the situation of grasping an empty needle and improving the operation efficiency of the equipment.

[0012] Further, a thimble groove that can only accommodate one syringe needle is provided on the upper surface of the thimble plate, and the bottom of the thimble groove is arc-shaped.

[0013] In this application, the thimble groove can only accommodate one needle, which can meet the usage requirements during the feeding process, with a simple structure, convenient disassembly, installation and use.

[0014] Further, the lower end of the thimble plate is detachably connected to the driving device fixed on the bracket.

[0015] In this application, the driving device can be a cylinder lifting device or a lead screw lifting device. During the lifting process of the thimble plate, it is necessary to ensure that it moves vertically up and down. The thimble plate is set at 90 degrees to the bottom plate seat and cannot be tilted to avoid the syringe needle falling during the lifting process and ensure the stability during the feeding process. The detection result is more accurate when cooperating with the optical fiber detection device. Using the cylinder lifting and the lead screw lifting to drive the thimble plate can meet the stability requirements of production feeding. During the operation process, the vibration amplitude is small and the stability is high.

[0016] Further, the side wall of the guide block opposite to the second inclined surface has a third inclined surface with an inclined design.

[0017] In this application, there is an adjustable gap between the guide block and the second inclined surface, which enables the syringe needle to pass through the gap, thus achieving the effect that the syringe needle slides from the left and right sides of the preparation area to the center of the area to be fed. The setting of the third inclined surface can achieve a better guiding effect. The third inclined surface and the second inclined surface cooperate to better ensure that the syringe needle passes through the gap, making the feeding process smoother and avoiding problems such as material jamming.

[0018] Further, the groove width of the material placing groove gradually decreases from top to bottom.

[0019] In the present application, the wide-mouthed discharge groove can play a guiding role, gather the needle tube inward, and limit the position through the guide block, so that the needle tube slides from both sides to the center, making it convenient for the staff to put in materials without stopping the machine for adding materials. The structure is simple, the convenience is high, and the production efficiency is improved.

[0020] Furthermore, the baffle is provided with a travel groove for the grabbing component to run through.

[0021] In the present application, the travel groove rail limits the travel position and trajectory of the grabbing component, thereby reducing the space occupied during the operation of the equipment and shortening the lifting and lowering stroke of the ejector plate, achieving efficient feeding, and making the grabbing trajectory more intuitive. In actual use, it is convenient for staff to observe and avoid accidentally blocking or assembling the equipment due to unclear operation trajectory, which may cause damage to the equipment or injury to personnel, thereby greatly improving safety.

[0022] In the present application, the directional feeding device can meet the coordination needs of production lines of different heights, and at the same time can meet the feeding needs of needle tubes of different specifications, and can detect them during the feeding process, combining detection and feeding into one, thereby improving the practicality of the directional feeding device, reducing the occupied space, shortening the detection and feeding time, and greatly improving production efficiency.

[0023] Beneficial effects:

[0024] The angle between the two first inclined surfaces set in the present application is greater than the angle between the two second inclined surfaces. Each time the ejector plate rises, a needle tube is driven up. The first inclined surface and the second inclined surface can guide and support the needle tube, and the running trajectories of all needle tubes are controlled to run from top to bottom along the second inclined surface and the first inclined surface to the bottom of the discharge groove. The needle tubes are accumulated in the center of the discharge groove. Different angles can be used to control the speed of the needle tube operation. At the same time, the needle tubes inside the discharge groove are brought closer to the center. The space inside the discharge groove is divided into two parts, one part is the area to be fed, and the needle tubes are in the area to be fed. The needle tubes are waiting to be fed in the preparation area, and the number of needle tubes piled in the feeding area is limited and smaller than that in the preparation area, so as to avoid the phenomenon that the needle tubes are piled up in a disorderly manner due to a large number of needle tubes. It is convenient for the needle plate to lift the needle tubes one by one, and ensure that the needle plate can only lift one needle tube in a single operation, so as to realize continuous feeding in a cycle, meet the production needs, effectively avoid disordered needles and skipped needles, and the guide block limits the guiding position of the needle tube, so that it will not be piled up in the middle position of the entire discharge groove, thereby realizing the effect of feeding without stopping the machine during the feeding process, and the feeding is convenient, and the structure is simple and easy to use.

[0025] This application provides an optical fiber detection device, which uses the optical fiber emitted by the optical fiber detection device to determine whether the ejector plate ejects the syringe needle. During the upward movement of the ejector plate, if there is a syringe needle on the ejector plate, then data information changes will occur in the optical fiber during the upward movement of the ejector plate. If there is no syringe needle on the ejector plate, then no data information changes will occur in the optical fiber during the upward movement of the ejector plate. The detection is convenient, with a high degree of intelligence, fast detection speed and high efficiency. In addition, since the optical fiber detection device can sense small changes, it can effectively improve the accuracy of the detection work. Cooperating with the grasping component can achieve 100% effective feeding and grasping, avoid the situation of grasping an empty needle, and improve the operation efficiency, production speed and efficiency of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] To deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The embodiments are only used to explain the present utility model and do not limit the protection scope of the present utility model.

[0033] Embodiment 1

[0034] As Figures 1 to 5 shown as a specific embodiment of the present utility model, a medical syringe needle directional feeding device includes a support 1, a material supporting seat 2, an ejector plate 3, a baffle 4, a material placing groove 5, a first inclined surface 6, a second inclined surface 7, a guiding through hole 8, an optical fiber mounting plate 9, an optical fiber detection device 10, a third inclined surface 11, an ejector pin groove 12, a guiding block 13, a detection notch 14, and a stroke groove rail 15.

[0035] In this embodiment, the directional feeding device includes a bracket 1. A material supporting seat 2 is provided on the bracket 1. A material placing groove 5 is formed on the upper surface of the material supporting seat 2. A guiding through hole 8 is formed at the bottom of the material placing groove 5. Below the material supporting seat 2, there is a thimble plate 3 that penetrates through the guiding through hole 8 and can move up and down reciprocally. A baffle 4 is connected to the side wall of the material supporting seat 2. Both side walls of the material placing groove 5 have a first inclined surface 6 and a second inclined surface 7 that extend obliquely upward from bottom to top, and the first inclined surface 6 and the second inclined surface 7 are connected to each other. The first inclined surface 6 and the second inclined surface 7 are symmetrically arranged with the guiding through hole 8 as the center. The inclination of the first inclined surface 6 is greater than that of the second inclined surface 7. The first inclined surface 6 and the second inclined surface 7 can both guide and support the syringe needles, and control the running trajectories of all syringe needles to run from top to bottom along the second inclined surface 7 and the first inclined surface 6 to the bottom of the material placing groove 5. The syringe needles are stacked inside the material placing groove 5. Each time the thimble plate 3 rises, it can drive one syringe needle to rise, realizing intelligent automatic feeding. The thimble plate 3 moves up and down reciprocally inside the guiding through hole 8. The included angle between the two first inclined surfaces 6 is greater than the included angle between the two second inclined surfaces 7. Using different included angles can control the running speed of the syringe needles differently, and at the same time, move the syringe needles inside the material placing groove 5 towards the center. The space inside the material placing groove 5 is divided into two parts. One part is the area to be fed. The syringe needles in the area to be fed wait for the thimble plate 3 to lift the syringe needles for feeding. The other part is the preparation area. The syringe needles in the preparation area wait to enter the area to be fed. This makes the number of stacked syringe needles in the area to be fed limited and less than the number of stacked syringe needles in the preparation area, avoiding the phenomenon of the syringe needles being in a mess due to a large number of stacked syringe needles, facilitating the thimble plate 3 to lift the syringe needles one by one, ensuring the requirement that the thimble plate 3 can only lift one syringe needle during a single operation, realizing continuous cyclic feeding, meeting the production needs, and effectively avoiding needle jamming and skipping needles.

[0036] Above the connection of the first inclined surface 6 and the second inclined surface 7, guiding blocks 13 that are rotatably connected to the side wall of the baffle 4 are provided. The rotatable baffle 4 can adjust the distance between the guiding block 13 and the side wall of the material placing groove 5, meeting the feeding requirements of syringe needles with different diameters. During the feeding process, a small number of syringe needles are stacked in the area to be fed, and most of the syringe needles are stacked in the preparation area, which can effectively prevent too many syringe needles from being stacked in the area to be fed and causing the syringe needles to be messy during the feeding process. In addition, the adjustment function of the guiding block 13 can better adapt to the feeding of syringe needles with different lengths and diameters, achieving the effects of convenient feeding and simple adjustment, and greatly improving the practicability.

[0037] Both ends of the stock support 2 are provided with optical fiber mounting plates 9 for mounting the optical fiber detection device 10. The optical fiber detection device 10 can be installed at any height position on the optical fiber mounting plate 9, which can better adapt to the detection of the ejector pin plate 3 at different lifting heights. The optical fiber detection device 10 is used to detect whether the needle tube is ejected by the ejector pin plate 3. The optical fiber detection device 10 can convert the information detected during the operation of the optical fiber into a regular electrical signal output. It has the characteristics of sensitivity, small size, convenient installation, strong adaptability, low cost, and good accuracy, meeting the needs of large-scale or mass detection. After the optical fiber detection device 10 detects a needle tube on the ejector pin plate 3, the grasping component runs through the stroke slot rail 15 to the upper part of the ejector pin plate 3 to grasp the needle tube, and then continues to run to the next station. When the detection data of the optical fiber detection device 10 shows that there is no needle tube on the ejector pin plate 3, the grasping component does not perform the grasping operation until the optical fiber detection device 10 detects a needle tube on the ejector pin plate 3 to perform the grasping operation, which can effectively avoid the occurrence of ineffective strokes, ensure the operation efficiency and accuracy, and at the same time ensure the accuracy of the production data automatically generated after the equipment runs and the production volume after the equipment runs.

[0038] A detection notch 14 for passing through the optical fiber emitted by the optical fiber detection device 10 is opened on the upper surface of the ejector pin plate 3. During the upward movement of the ejector pin plate 3, the optical fiber passes horizontally from top to bottom through the detection notch 14. During this process, if there is a regular abnormal change in the optical fiber, it means that there is a needle tube on the ejector pin plate 3. If there is no change in the optical fiber, it means that there is no needle tube on the ejector pin plate 3. That is to say, the position of the optical fiber emitted by the optical fiber detection device 10 remains unchanged. During the upward movement of the ejector pin plate 3, if there is a needle tube on the ejector pin plate 3, then data information changes will occur to the optical fiber during the upward movement of the ejector pin plate 3. If there is no needle tube on the ejector pin plate 3, then no data information changes will occur to the optical fiber during the upward movement of the ejector pin plate 3. Due to the excellent detection effect of the optical fiber detection device 10 and the perception effect of small changes, it can effectively meet the detection requirements, improve the accuracy during the detection process, and cooperate with the grasping component to achieve 100% effective feeding and grasping, avoid the situation of grasping empty needles, and improve the operation efficiency of the equipment.

[0039] An ejector pin slot 12 that can only accommodate one needle tube is opened on the upper surface of the ejector pin plate 3, and the bottom of the ejector pin slot 12 is arc-shaped. The ejector pin slot 12 that can only accommodate one needle can meet the use requirements during the feeding process. The structure is simple, and it is convenient for disassembly, installation, and use. The diameter and specification of the ejector pin plate 3 for feeding can be adjusted according to needs. The practicality of the directional feeding device can be enhanced by replacing different ejector pin plates 3, and the use is more extensive.

[0040] The lower end of the thimble plate 3 is detachably connected to the driving device fixed on the bracket 1. The driving device is a cylinder lifting device. During the lifting process of the thimble plate 3, it is necessary to ensure that it moves vertically up and down. The thimble plate 3 is set at 90 degrees to the bottom plate seat without inclination to avoid the needle tube falling during the lifting process, ensure the stability during the feeding process, and make the detection result more accurate after cooperating with the optical fiber detection device 10. Using both cylinder lifting and screw rod lifting to drive the thimble plate 3 can meet the stability requirements of production feeding. During the operation process, the vibration amplitude is small and the stability is high.

[0041] The side wall of the guide block 13 opposite to the second inclined surface 7 has a third inclined surface 11 with an inclined design. There is an adjustable gap between the guide block 13 and the second inclined surface 7, which enables the needle tube to pass through the gap, thus realizing the effect that the needle tube slides from the left and right sides of the preparation area to the center of the area to be fed. The setting of the third inclined surface 11 can play a better guiding effect. The cooperation between the third inclined surface 11 and the second inclined surface 7 can better ensure that the needle tube passes through the gap, making the feeding process smoother and avoiding problems such as material jamming.

[0042] The bracket 1 includes a bottom plate seat. The two ends of the bottom plate seat are respectively connected to the support plates through adjustable struts. The length of the adjustable struts is adjustable. Extending the adjustable struts can drive the bottom plate seat to rise simultaneously, and shortening the adjustable struts can drive the bottom plate seat to fall simultaneously, meeting the lifting use of thimble plates 3 with different lengths. At the same time, it can better cooperate with different production lines or grasping components, meet the use requirements of multiple scenarios and multiple devices, and has strong practicability, which is very suitable for large-scale production.

[0043] The groove width of the lower end groove bottom to the upper end groove opening of the feeding groove 5 gradually increases. The wide-mouth feeding groove 5 can play a guiding role, gather the needle tubes inward, and be limited by the guide block 13, enabling the needle tubes to slide from both sides to the center, facilitating the staff to input materials without stopping the machine for feeding. The structure is simple, the convenience degree is high, and the production efficiency is improved.

[0044] The baffle 4 has a travel groove rail 15 for the grasping component to run through. The travel groove rail 15 limits the travel position and trajectory of the grasping component, reduces the floor space occupied during the operation of the equipment, and at the same time shortens the lifting travel of the thimble plate 3, realizing efficient feeding. The grasping trajectory is more intuitive, which is convenient for the staff to observe during actual use, avoiding accidentally blocking or assembling it due to unclear running trajectories, resulting in equipment damage or personal injury, and greatly improving the safety.

[0045] In this application, the directional feeding device can meet the cooperation requirements of production lines at different heights, and at the same time can meet the feeding requirements of needle tubes of different specifications, and can detect them during the feeding process, combining detection and feeding into one, improving the practicability of the directional feeding device, reducing the occupied space, shortening the time for detection and feeding, and greatly improving the production efficiency.

[0046] Working process:

[0047] First, put the syringe into the feeding groove 5. The syringe slides from the gap between the guiding block 13 and the second inclined surface into the area to be fed, that is, it slides from both inner sides of the feeding groove 5 to its center. By using different included angles, different control of the running speed of the syringe can be achieved. At the same time, the syringes inside the feeding groove 5 are moved closer to its center. The space inside the feeding groove 5 is divided into two parts. The installation angle and position of the guiding block 13 can be adjusted according to the specifications and diameters of the syringes to ensure that a small number of syringes enter the area to be fed in sequence, and most of the syringes remain in the preparation area waiting to enter the area to be fed in sequence. The number of syringes in the area to be fed is small, avoiding the phenomenon of syringes being stacked in a disorderly manner, which is convenient for the thimble plate 3 to lift the syringes one by one, ensuring that the thimble plate 3 can only lift one syringe in a single operation, realizing continuous cyclic feeding, meeting the production needs, effectively avoiding needle jamming and skipping. The thimble plate 3 is driven by a driving device to rise and fall. During the rising process, the thimble plate 3 passes through the guiding through-hole 8 and lifts a syringe. Then it continues to rise until it reaches the limit position. During this process, the optical fiber detection device 10 detects whether there is a lack of material. When a syringe is detected, the grasping component is started to grasp the syringe, thus entering the next step. When no syringe is detected, the grasping component is not started, and the driving device continues to drive the thimble plate 3 to perform cyclic needle-taking movements, thereby realizing efficient automatic feeding.

[0048] Embodiment 2

[0049] This is the second driving device mode of the ejector plate 3 in the present application. In this embodiment, other structures are basically the same as those in the first embodiment. The difference is that the driving device is a screw lifting device. The ejector plate 3 must be ensured to be lifted vertically during the lifting process. The ejector plate 3 is set at 90 degrees to the base plate seat and cannot be tilted to avoid the needle tube from falling during the lifting process, thereby ensuring the stability of the feeding process and the detection result after cooperating with the optical fiber detection device 10 is more accurate. The use of a screw lifting drive to drive the ejector plate 3 can meet the stability requirements of production feeding. The vibration amplitude is small and the stability is high during operation. The angle between the two first inclined surfaces 6 is smaller than the angle between the two second inclined surfaces 7. The first inclined surface 6 and the second inclined surface 7 can both guide and support the needle tube, and control the running trajectory of all needle tubes to run from top to bottom along the second inclined surface 7 and the first inclined surface 6 to the bottom of the discharge groove 5. The needle tubes are accumulated inside the discharge groove 5. The rise can drive a needle tube to rise, realizing intelligent automatic feeding, the ejector plate 3 reciprocates up and down inside the guide through hole 8, the angle between the two first inclined surfaces 6 is smaller than the angle between the two second inclined surfaces 7, and different angles can be used to realize the control of different degrees of rapidity and slowness of the needle tube operation, and at the same time, the needle tube inside the discharge groove 5 is brought closer to its center, and the space inside the discharge groove 5 is divided into two parts, one part is the waiting feeding area, and the needle tube waits in the waiting feeding area for the ejector plate 3 to lift the needle tube for feeding, and the other part is the preparation area, and the needle tube in the preparation area waits to enter the waiting feeding area, which makes the number of needle tubes accumulated in the waiting feeding area limited and smaller than the number of needle tubes accumulated in the preparation area, avoiding the phenomenon that the needle tubes are piled up in a disorderly manner due to a large number of needle tubes, making it convenient for the ejector plate 3 to lift the needle tubes one by one, ensuring that the ejector plate 3 can only lift one needle tube in a single operation, realizing cyclic continuous feeding, meeting production needs, and effectively avoiding disordered needles and skipped needles.

[0050] Embodiment 3

[0051] This is the second structure of the ejector plate 3 in the present application. In this embodiment, other structures are basically the same as those in the first embodiment, except that: the length of the ejector groove is equal to the length of the upper surface of the ejector plate. When the length of the needle tube is greater than the length of the ejector groove, the two ends of the needle tube extend from the two ends of the ejector groove to the outside of the ejector plate. At this time, the optical fiber emitted by the optical fiber detection device passes horizontally from the two ends of the ejector groove. By detecting the two ends of the needle tube, the function of detecting whether there is a needle tube in the ejector groove is achieved.
