Technical Field

[0001] The present invention relates to the technical field of tire detection, and particularly to a fully automatic tire pressure detection device for electric bicycle tires. Background Art

[0002] Tires are an important part of the driving mechanism of electric bicycles. As important supporting and walking components, tires not only bear the entire mass of the electric bicycle, but also provide propulsion force for the electric bicycle to move forward, and at the same time play a role in buffering ground impacts.

[0003] In existing tire assembly plants, only a small number of finished tires are sent to the general assembly plant directly for the assembly of electric bicycles after the tires are inflated and assembled. Most of the other tires are sent to the finished product warehouse or the freight transfer warehouse for storage. After the tires are left standing for a period of time, the tires may leak air and cause insufficient tire pressure, so it is necessary to detect the tire pressure. When the existing tire pressure detection equipment detects the tire pressure, it is necessary to align and connect the detection joint with the tire valve nozzle, and this operation is aligned manually, resulting in a low degree of automation and low detection efficiency of the tire pressure detection equipment.

Detailed Description of the Invention

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Embodiment: This embodiment discloses a fully automatic tire pressure detection device for an electric bicycle tire, as Figures 1-6As shown in the figure, it includes a base 1, a clamping mechanism 2, a lifting mechanism 4 and a detection mechanism 5. A rotating disk 3 is rotatably connected to the base 1. The rotating disk 3 is used to place the electric bicycle tire. The clamping mechanism 2 clamps and positions the tire. The lifting mechanism 4 is used to drive the detection mechanism 5 to lift and lower. The lifting mechanism 4 uses a cylinder. The detection mechanism 5 is used to align and connect with the tire valve to detect the tire pressure. After the detection, the lifting mechanism 4 drives the detection mechanism 5 to rise, which does not affect the taking and placing of the tire.

[0026] As Figures 2-3 shown, the detection mechanism 5 includes: a connecting seat 51, the connecting seat 51 is fixedly connected to the lifting mechanism 4. A positioning plate 52 is connected below the connecting seat 51. A positioning groove 515 that cooperates with the tire valve is provided at the lower end of the positioning plate 52. The lower end of the positioning groove 515 is trumpet-shaped, and the width of the positioning groove 515 is the same as the diameter of the valve. A stop block 516 is fixedly connected above the positioning groove 515. When the valve is stuck in the positioning groove 515 and contacts the stop block 516, the position of the steel pipe of the detection joint 53 is aligned with the position of the valve. A sliding frame 511 that is slidably connected to the positioning plate 52 is fixedly connected to the connecting seat 51. An elastic member 510 is fixedly connected between the connecting seat 51 and the positioning plate 52. The elastic member 510 uses a spring. A horizontally arranged guide frame 55 is perpendicularly and fixedly connected to the positioning plate 52. A moving seat 56 is slidably connected to the guide frame 55. The moving seat 56 is fixedly connected to a fixing plate 57. A detection joint 53 that cooperates with the tire valve is connected to the fixing plate 57. A detector 518, the detector 518 uses an electronic display instrument. The detector 518 is connected to the detection joint 53 through an air pipe 519. The air pipe 519 uses a flexible pipe to facilitate the lowering of the connecting seat 51. Among them, a lead screw 58 is rotatably connected inside the guide frame 55. The moving seat 56 is threadedly connected to the lead screw 58. One end of the lead screw 58 is fixedly connected to a first gear 59. A rack 513 that meshes with the first gear 59 is fixedly connected to the connecting seat 51. Specifically, during implementation: when the lifting mechanism 4 drives the detection mechanism 5 to lower, the connecting seat 51 and the positioning plate 52 descend as a whole. The valve is stuck in the positioning groove 515, thereby fixing the position of the valve. When the detection mechanism 5 continues to lower, the positioning plate 52 does not move, and the connecting seat 51 descends. The rack 513 drives the first gear 59 and the lead screw 58 to rotate, driving the moving seat 56 and the detection joint 53 to move towards the valve to wait for the detection joint 53 to connect with the valve.

[0027] Preferably, a rotating rod 514 is rotatably connected to the positioning plate 52. The rotating rod 514 is arranged below the lead screw 58. One end of the rotating rod 514 is fixedly connected to a second gear 512 that meshes with the rack 513. The second gear 512 and the first gear 59 are arranged on the same side of the positioning plate 52. A locking disc 54 is slidably connected to the rotating rod 514 for connecting the detection joint 53 to the tire valve. When the rotating rod 514 rotates, it drives the locking disc 54 to rotate together; a sliding sleeve 543 is fixedly connected to the locking disc 54. The sliding sleeve 543 is rotatably connected to the fixing plate 57 and is slidably connected to the rotating rod 514. A sliding strip is arranged on the surface of the rotating rod 514. When the moving seat 56 moves, it drives the locking disc 54 to move together.

[0028] Preferably, as Figures 4-5 shown, a track plate 541 with a gradually increasing thickness is fixedly connected to the surface of the locking disc 54. A guide rail 542 is arranged on the surface of the track plate 541. A limiting plate 532 is fixedly connected to the detection joint 53. A guide rail groove 533 that is cooperatively connected to the guide rail 542 is arranged on the limiting plate 532, so that the track plate 541 and the limiting plate 532 remain connected. When the locking disc 54 rotates, it can drive the detection joint 53 to move back and forth; when the connecting seat 51 continues to descend, the rack 513 is separated from the first gear 59 and meshes with the second gear 512. The rack 513 drives the second gear 512 and the rotating rod 514 to rotate. When the rotating rod 514 rotates, it drives the locking disc 54 to rotate. When the locking disc 54 rotates, it drives the detection joint 53 to move, so that the detection joint 53 is aligned with and pressed against the valve nozzle, ensuring stable connection between the two. The air pressure of the tire is detected by the detector 518.

[0029] Preferably, an installation groove 520 that cooperates with the detection joint 53 is arranged on the fixing plate 57. An arc groove is arranged in the installation groove 520. The detection joint 53 is slidably connected to the installation groove 520, and a strip rail 531 that is slidably matched with the installation groove 520 is arranged on the surface of the detection joint 53. The detection joint 53 can slide back and forth in the installation groove 520.

[0030] As Figure 5As shown in the figure, there are a pair of clamping mechanisms 2, which are symmetrically arranged on both sides of the rotating disk 3. The clamping mechanism 2 includes: a sliding seat 21, and a slide rail 6 is provided on the base 1 and is slidably connected to the sliding seat 21; a clamping seat 23 is fixedly connected to the sliding seat 21. The clamping seat 23 is arc-shaped, and a plurality of positioning wheels 24 are rotatably connected to the clamping seat 23. In this embodiment, the number of positioning wheels 24 is two, which are respectively connected to both ends of the clamping seat 23; a double-headed cylinder 22, the double-headed cylinder 22 is fixedly installed on the base 1, and the piston rod of the double-headed cylinder 22 is fixedly connected to the sliding seat 21; a driving motor 26, which is installed on the clamping seat 23, and a driving wheel 25 is fixedly connected to the rotating shaft of the driving motor 26, which is used to drive the tire to rotate; the double-headed cylinder 22 drives the two sliding seats 21 to slide, the positioning wheels 24 clamp and position the tire, and then the driving motor 26 drives the driving wheel 25 to rotate, driving the tire and the rotating disk 3 to rotate together, and turning the valve stem to a position directly below the detection mechanism 5.

[0031] Preferably, it further includes an identification camera 517 and a control module 27. The identification camera 517 is installed on the positioning plate 52 and is located directly above the positioning groove 515. The identification camera 517 identifies the position of the valve stem through image acquisition. Among them, the identification image features mainly rely on the shape of the valve stem. When the valve stem rotates to a position directly below the identification camera 517, the identification camera 517 sends a signal to the control module 27, and the control module 27 controls the driving motor 26 to stop.

[0032] Working principle: When the electric bicycle tire is conveyed on the assembly line, the electric bicycle tire is placed on the rotating disk 3 by a machine device, and then the clamping mechanism 2 clamps and positions the tire. The driving motor 26 drives the tire and the rotating disk 3 to rotate together. When the valve stem rotates to a position directly below the detection mechanism 5, the control module 27 controls the driving motor 26 to stop; then the lifting mechanism 4 drives the detection mechanism 5 to descend, and the connecting seat 51 and the positioning plate 52 descend simultaneously. The valve stem is stuck in the positioning groove 515, and the stopper 516 limits the valve stem. When the detection mechanism 5 continues to descend, the positioning plate 52 does not move, and the connecting seat 51 descends. The rack 513 drives the first gear 59 and the lead screw 58 to rotate, driving the moving seat 56 to move, driving the detection joint 53 to move towards the valve stem. When the valve stem just contacts the detection joint 53, the rack 513 is separated from the first gear 59. As the connecting seat 51 continues to descend to a specified height, the rack 513 drives the second gear 512 and the rotating rod 514 to rotate. When the rotating rod 514 rotates, it drives the locking disc 54 to rotate, driving the detection joint 53 to move, so that the detection joint 53 is tightly connected to the valve stem. The locking disc 54 also has the effect of pressing and locking the detection joint 53. Then, the tire pressure is automatically detected by the detector 518, and the data is uploaded to the computer, thus completing the full-automatic detection of the tire pressure.

[0033] Finally, it should be noted that in the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
