Description

Technical Field

[0001] This utility model relates to the field of perpendicularity detection technology, and in particular to a device for detecting the perpendicularity of syringe needle tips. Background Technology

[0002] In the syringe manufacturing process, needle tip perpendicularity is a key indicator affecting syringe quality and safety. Therefore, efficient and reliable testing equipment is needed to test needle tip perpendicularity. Existing technologies may have the following shortcomings: traditional testing equipment may require workers to manually operate the clamping components to move or adjust the needle position, which is labor-intensive and has low testing efficiency; existing equipment may rely on multiple independent power sources to drive the clamping components to move and rotate, making it difficult to achieve multi-angle rotation of the needle during the testing process, resulting in complex structure, high cost, and difficult maintenance.

[0003] To address the aforementioned issues, this invention provides a syringe needle tip perpendicularity detection device with a simple structure and a high degree of automation. By using a motor to drive a rotating wheel and the meshing transmission of gears, bevel gears, and other gears, the device integrates the movement and rotation functions of the clamping components, enabling needle tip transfer and multi-angle detection without the need for an additional power source. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a device for detecting the perpendicularity of syringe needle tips. The device includes a motor-driven rotating wheel with teeth on one-quarter side surface, which drives a gear to rotate. This rotation of the rotating roller causes the conveyor belt to move, moving the clamping component to the detection area where it stops for testing. This facilitates the installation of the next needle to be tested. The device also allows the second bevel gear to mesh with the first bevel gear. When the teeth are not meshing with the gear, they continue to drive the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate, which in turn drives the clamping component to rotate. This allows the needle to rotate in front of the detection component, facilitating thorough needle testing. No additional power source is required. After testing, the teeth, no longer meshing with the bevel gear, will re-mesh with the gear, moving the clamping component. The device has a simple and easy-to-use structure, requiring no manual operation by staff, thus reducing labor intensity.

[0005] This utility model also provides a device for detecting the perpendicularity of syringe needle tips, comprising: a base, a light shield fixedly connected to the upper surface of the base, a light emitter and a light receiver fixedly connected to the upper surface of the base, a motor fixedly connected to the front of the base, a rotating wheel fixedly connected to the output end of the motor, gear teeth fixedly connected to the side surface of the rotating wheel, a gear meshing with the gear teeth, a rotating roller fixedly connected to the side surface of the gear, a conveyor belt drivingly connected to the side surface of the rotating roller, and a first bevel gear rotatably connected to the upper surface of the base; a support plate, a clamping seat rotatably connected to the upper surface of the support plate, a second bevel gear fixedly connected to the side surface of the clamping seat, a clamping plate slidably connected to the inner side wall of the clamping seat, a spring fixedly connected to the side surface of the clamping plate, and a pull rod fixedly connected to the side surface of the clamping plate. The above components include a motor-driven rotating wheel with teeth on one-quarter side surface. These teeth drive a gear, which in turn rotates a roller, causing the conveyor belt to move. This moves the clamping component to the detection area, where it stops for inspection. This facilitates the installation of the next needle to be tested. The system also allows the second and first bevel gears to mesh. When the teeth are not meshing with the gears, they continue to drive the first bevel gear, which in turn drives the second bevel gear. This, in turn, drives the clamping component, allowing the needle to rotate in front of the detection component for thorough testing. No additional power source is required. After testing, the teeth, which were not meshing with the bevel gears, will re-engage with them, moving the clamping component. The device is simple and easy to use, requiring no manual operation and reducing worker workload.

[0006] According to the present invention, a device for detecting the perpendicularity of a syringe needle tip is provided, wherein the light emitter and the light receiver are located on both sides of a conveyor belt, and both the light emitter and the light receiver face the conveyor belt. These components enable the light emitter to emit light onto the syringe needle tip, and the light receiver to detect the shape of the needle tip.

[0007] According to the present invention, a device for detecting the perpendicularity of a syringe tip is provided, wherein the rotating wheel is rotatably connected to the inner wall of the base, and the wheel teeth are a plurality of teeth arranged in an array on a quarter-side surface of the rotating wheel. These components enable the rotating wheel to rotate normally, allowing the wheel teeth to move the syringe and then stop for testing, before continuing to test the next syringe.

[0008] According to the present invention, a device for detecting the perpendicularity of a syringe needle tip is provided, wherein the rotating roller and gear are rotatably connected to the inner wall of the base, and the conveyor belt is movably connected to the upper surface of the base. These components enable the rotating roller, gear, and conveyor belt to operate normally.

[0009] According to the present invention, a device for detecting the perpendicularity of a syringe needle tip is provided, wherein the gear teeth mesh with the side surface of a first bevel gear, and the lower surface of the support plate is fixedly connected to the upper surface of the conveyor belt. These components enable the gear teeth to drive the first bevel gear to rotate, providing support for the support plate and facilitating the movement of the syringe.

[0010] According to the present invention, a device for detecting the perpendicularity of syringe needle tips is provided, wherein the support plate has several components arranged in an array on the upper surface of the conveyor belt, and the side surface of the second bevel gear meshes with the side surface of the first bevel gear. These components facilitate automated testing of syringes, requiring only a single power source to control the movement and rotation of the syringe.

[0011] According to the present invention, a device for detecting the perpendicularity of a syringe needle tip is provided, comprising two clamping plates located on both sides of a clamping seat, wherein the end of a spring away from the clamping plates is fixedly connected to the inner wall of the clamping seat. These components facilitate stable clamping of the syringe, allowing the spring to drive the clamping plates to return to their original position and hold the syringe securely.

[0012] According to the present invention, a device for detecting the perpendicularity of a syringe tip is provided on the inner wall of the clamping plate, and the syringe is located between a light emitter and a light receiver. These components facilitate the detection of the syringe tip.

[0013] Beneficial effects:

[0014] Compared with the prior art, this utility model is equipped with a motor-driven rotating wheel. A quarter-side surface of the wheel has teeth that drive a gear to rotate, which in turn drives a rotating roller, causing the conveyor belt to move. This moves the clamping component to the detection area and stops for testing, facilitating the installation of the next needle to be tested. The second bevel gear meshes with the first bevel gear. When the teeth are not meshing with the gear, they continue to drive the first bevel gear to rotate, which in turn drives the second bevel gear. This allows the second bevel gear to drive the clamping component to rotate, enabling the needle to rotate in front of the detection component for thorough testing. No additional power source is required. After testing, the teeth, which were not meshing with the bevel gear, will re-mesh with the gear, moving the clamping component. The device has a simple and easy-to-use structure, requiring no manual operation and reducing the workload of workers. Attached Figure Description

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model discloses a device for detecting the perpendicularity of syringe needle tips, comprising: a base 1, a light shield 2 fixedly connected to the upper surface of the base 1, a light emitter 3 and a light receiver 4 fixedly connected to the upper surface of the base 1, a motor 5 fixedly connected to the front of the base 1, a rotating wheel 6 fixedly connected to the output end of the motor 5, the rotating wheel 6 being rotatably connected to the inner side wall of the base 1, a gear tooth 7 fixedly connected to the side surface of the rotating wheel 6, the gear tooth 7 having several teeth arranged in an array on a quarter side surface of the rotating wheel 6, a gear 8 meshing with the gear tooth 7, a rotating roller 9 fixedly connected to the side surface of the gear 8, the rotating roller 9 and the gear 8 being rotatably connected to the inner side wall of the base 1, a conveyor belt 10 being drivenly connected to the side surface of the rotating roller 9, the conveyor belt 10 being movably connected to the upper surface of the base 1, the light emitter 3 and the light receiver 4 being located on both sides of the conveyor belt 10, both the light emitter 3 and the light receiver 4 facing the direction of the conveyor belt 10, a first bevel gear 11 rotatably connected to the upper surface of the base 1, and the gear tooth 7 meshing with the side surface of the first bevel gear 11.

[0024] Specifically, the starting motor 5 can rotate the wheel 6, causing the teeth 7 on its side surface to drive the gear 8 to rotate. The gear 8 drives the rotating roller 9 to rotate, causing the conveyor belt 10 to move the clamping components on its surface. Since the teeth 7 are distributed on a quarter of the side surface of the wheel 6, the teeth 7 can drive the first bevel gear 11 to rotate. The first bevel gear 11 can drive the second bevel gear 14 to rotate, thereby driving the clamping components and the syringe 18 inside to rotate. The starting light emitter 3 can emit light to illuminate the needle tip of the syringe 18. The part of the light not blocked by the needle tip shines on the light receiver 4. The received light can obtain the shape of the needle tip through the shadow. Since the needle tip is rotating, the verticality of the needle tip can be known when the shadow changes.

[0025] A support plate 12 is fixedly connected to the upper surface of the conveyor belt 10 on its lower surface. Several support plates 12 are arranged in an array on the upper surface of the conveyor belt 10. A clamping seat 13 is rotatably connected to the upper surface of the support plate 12. A second bevel gear 14 is fixedly connected to the side surface of the clamping seat 13. The side surface of the second bevel gear 14 meshes with the side surface of the first bevel gear 11. A clamping plate 15 is slidably connected to the inner wall of the clamping seat 13. There are two clamping plates 15 located on both sides of the clamping seat 13. An syringe 18 is provided on the inner wall of the clamping plate 15. The syringe 18 is located between the light emitter 3 and the light receiver 4. A spring 16 is fixedly connected to the side surface of the clamping plate 15. The end of the spring 16 away from the clamping plate 15 is fixedly connected to the inner wall of the clamping seat 13. A pull rod 17 is fixedly connected to the side surface of the clamping plate 15.

[0026] Specifically, pulling the lever 17 causes the clamping plate 15 to move against the elastic force of the spring 16, placing the syringe 18 between the clamping plates 15. Releasing the lever 17 allows the clamping plate 15 to hold the syringe 18, enabling the device to detect the syringe 18. At this time, the first bevel gear 11 can drive the second bevel gear 14 to rotate, realizing the rotation of the needle tip to facilitate the detection of perpendicularity.

[0027] Working principle: During use, pulling the lever 17 causes the clamping plate 15 to move against the spring force of the spring 16, placing the syringe 18 between the clamping plates 15. Releasing the lever 17 allows the clamping plates 15 to hold the syringe 18, enabling the device to inspect the syringe 18. At this time, the first bevel gear 11 drives the second bevel gear 14 to rotate, realizing the rotation of the needle tip for easy perpendicularity inspection. Starting the motor 5 rotates the rotating wheel 6, causing the teeth 7 on its side surface to drive the gear 8 to rotate. The gear 8 drives the rotating roller 9 to rotate, causing the conveyor belt 1 to move. 0 drives the clamping components on its surface to move. Since the gear teeth 7 are distributed on the quarter side surface of the rotating wheel 6, the gear teeth 7 can drive the first bevel gear 11 to rotate. The first bevel gear 11 can drive the second bevel gear 14 to rotate, thereby driving the clamping components and the syringe 18 inside to rotate. Activating the light emitter 3 can emit light to illuminate the needle tip of the syringe 18. The part of the light that is not blocked by the needle tip shines on the light receiver 4. The received light can obtain the shape of the needle tip through the shadow. Since the needle tip is rotating, the verticality of the needle tip can be known when the shadow changes.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
