Description

Technical Field

[0001] This invention relates to the technical field of valve core assembly, and in particular to a fully automatic valve core assembly machine. Background Technology

[0002] The valve core is a key component used in pneumatic tires, mainly for controlling tire inflation and deflation and preventing air leakage; assembly machines are used in the production and assembly of valve cores.

[0003] In the existing assembly machine, the setting of the first assembly mechanism and the second assembly mechanism changes the phenomenon that the traditional valve core assembly equipment can only perform a single assembly operation and cannot perform two different assembly operations at the same time.

[0029] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0030] This invention discloses a fully automatic valve core assembly machine. (Refer to...) Figures 1-8 A fully automatic valve core assembly machine includes a housing 1, a fixed cylinder 2 fixedly connected to the middle of the housing 1, a storage structure set on the housing 1 around the fixed cylinder 2, a plurality of storage cylinders 10 set on the fixed cylinder 2 by a lifting structure, and an assembly structure set on the side of the fixed cylinder 2 near the top.

[0031] The lifting structure includes a screw 5 that is inserted into the fixed cylinder 2. A first motor 3 is installed at the top of the fixed cylinder 2. The bottom end of the output shaft of the first motor 3 is connected to the screw 5. A lifting plate 6 is set inside the fixed cylinder 2. A threaded groove for the screw 5 to pass through is opened on the axis of the lifting plate 6. Multiple guide grooves 4 are opened at equal angles on the side circumference of the fixed cylinder 2. A connecting block 7 is set at each guide groove 4 on the side of the lifting plate 6. A lifting ring 8 is movably sleeved in the middle of the outer side of the fixed cylinder 2. The connecting block 7 is connected to the lifting ring 8. A lifting plate 9 is fixedly sleeved on the outer side of the lifting ring 8. The lifting plate 9 is an annular plate. Multiple third grooves 41 are opened at equal angles on the side circumference of the lifting plate 9. A storage cylinder 10 is set in each third groove 41 through a flipping structure. A clamping structure is set on each storage cylinder 10.

[0032] The assembly structure includes a first assembly plate 11 fixedly sleeved on the top of the side of the fixed cylinder 2. A core assembly mechanism is provided under the first assembly plate 11 corresponding to each third groove 41. Multiple connecting rods 12 are connected to the side of the first assembly plate 11. One end of the connecting rod 12 is connected to the second assembly plate 13. A core spring assembly mechanism is provided on the inner side of the second assembly plate 13 corresponding to each third groove 41.

[0033] The clamping structure includes an electric telescopic rod 18 installed in the middle of the inner wall of the flipping frame 17. One end of the output shaft of the electric telescopic rod 18 is connected to a drive block 19. Two first rotating rods 21 are rotatably connected to the flipping frame 17. Two flip handles 16 are fixedly sleeved on each first rotating rod 21. Two clamping holes 14 are opened on the storage cylinder 10. A clamping strip 15 is set at one end of the flip handle 16 inserted into the clamping hole 14. A first gear 22 is fixedly sleeved in the middle of the first rotating rod 21. Drive strips 20 are set on both the upper and lower sides of the drive block 19. The drive strips 20 are provided with teeth that mesh with the first gear 22. The lifting plate 9 is located in the middle of the fixed cylinder 2. When the storage cylinder 10 is in a horizontal state, the assembled core seat, sealing gasket and core rod are loaded into the storage cylinder 10. The electric telescopic rod 18 is activated to drive the drive block 19 and drive strips 20 to move away from the storage cylinder 10. The first rotating rod 21 is rotated through the first gear 22. This causes the clamping bar 15 at one end of the flip handle 16 to clamp and fix the assembled core seat in the storage cylinder 10. Then, the first motor 3 is started to drive the screw 5 to rotate, and the lifting plate 6 moves upward on the rotating screw 5. Through the connecting block 7, the lifting ring 8 and the lifting plate 9 move upward on the fixed cylinder 2 as a whole. When the lifting plate 9 moves the core seat on the storage cylinder 10 to the first assembly plate 11, the core assembly mechanism on the first assembly plate 11 simultaneously performs core assembly work on the core seats of multiple storage cylinders 10. After assembly, the first motor 3 drives the screw 5 to move in the opposite direction, and the lifting plate 9 moves the storage cylinder 10 down to the second assembly plate 13. Through the core spring assembly mechanism on the second assembly plate 13, the core spring assembly work of multiple valve cores is performed simultaneously. Finally, the first motor 3 continues to drive the screw 5 to rotate, and the lifting plate 9 moves the assembled valve core down to the unloading position, and the clamping bar 15 is released to perform the unloading work.

[0034] See Figures 4-6 The flipping structure includes a second rotating rod 23 rotatably connected to the wall of the third groove 41, a flipping frame 17 fixedly sleeved on the second rotating rod 23, a storage cylinder 10 fixedly installed in the middle of the flipping frame 17, and a driving structure between the second rotating rod 23 and the fixed cylinder 2.

[0035] The driving structure includes multiple first grooves 27 on the inner side of the lifting plate 9. The first grooves 27 are positioned corresponding to the third grooves 41. A through strip 24 moves through the groove wall of the first groove 27. One end of the through strip 24 is inserted into the third groove 41 and connected to the driving frame 25. A second gear 26 is fixedly sleeved in the middle of the second rotating rod 23. The lower inner wall of the driving frame 25 has teeth that mesh with the second gear 26. A second groove 28 is opened at the other end of the through strip 24. A fixing plate 29 passes through the first groove 27. Both ends of the fixing plate 29 are fixedly connected to the fixing cylinder 2. A vertical groove 31 is opened on the fixing plate 29. A first driving groove 32 is opened on the fixing plate 29 and connects to the top of the vertical groove 31. A second driving groove 33 is opened on the fixing plate 29 and connects to the top of the first driving groove 32. The other end of the through strip 24 is fixedly passed through the driving rod 30. The driving rod 30 moves through the vertical groove 31.

[0036] A third driving groove 34 is provided on the fixed plate 29, which connects to the bottom end of the vertical groove 31. When the lifting plate 9 moves upward, it drives the driving rod 30 at one end of the through bar 24 to slide in the second driving groove 33, thereby driving the driving frame 25 at one end of the through bar 24 to move away from the fixed cylinder 2. Through the second gear 26, it drives the flipping frame 17 and the storage cylinder 10 to flip as a whole to a vertical state, so that the core assembly work can be carried out smoothly. When the lifting plate 9 moves downward, the driving rod 30 slides in the first driving groove 32. The drive frame 25 is pulled to move closer to the fixed cylinder 2, thereby causing the storage cylinder 10 to flip to an inclined state close to the second assembly plate 13, so as to smoothly carry out the core spring assembly work. When the lifting plate 9 moves the assembled valve core downward, the drive rod 30 slides in the third drive groove 34 to move the drive frame 25 to continue moving closer to the fixed cylinder 2, causing the storage cylinder 10 to flip to a vertical downward state. In this way, as the lifting plate 9 continues to move downward, the assembled valve core can be smoothly inserted into the storage structure for storage.

[0037] See Figures 1-3 The storage structure includes a fixing ring 35 fixedly installed on the chassis 1, a storage ring 36 rotatably set at the top of the fixing ring 35, and multiple storage slots 37 are opened at equal angles around the inner wall of the storage ring 36. A drive structure is set on the chassis 1.

[0038] The drive structure includes a second motor 39 mounted on the chassis 1 near the fixed ring 35. A fourth gear 40 is sleeved on the top of the output shaft of the second motor 39. A third gear 38 is fixedly sleeved on the side of the storage ring 36. The fourth gear 40 and the third gear 38 are meshed together. After the lifting plate 9 drives the assembled valve core into the storage slot 37 on the storage ring 36, the electric telescopic rod 18 is activated to drive the driving block 19 to move towards the flip frame 17, thereby releasing the valve core in the storage cylinder 10, so that the valve core can be smoothly inserted into the storage slot 37 for storage. After the lifting plate 9 moves up and resets, the second motor 39 is activated, and the storage ring 36 is rotated through the third gear 38 and the fourth gear 40, switching the upper and lower storage slots 37 of the storage ring 36 to the unloading position to continue receiving and storing the assembled valve core. This makes the valve core storage more organized and easier to retrieve.

[0039] The implementation principle of a fully automatic valve core assembly machine according to an embodiment of the present invention is as follows: First, the assembled valve core seat, sealing gasket, and valve core rod are loaded into the storage cylinder 10. The electric telescopic rod 18 is activated, causing the driving block 19 and driving strip 20 to move away from the storage cylinder 10. The first gear 22 drives the first rotating rod 21 to rotate, thereby causing the clamping strip 15 at one end of the flip handle 16 to clamp and fix the assembled valve core seat in the storage cylinder 10. Next, the first motor 3 is activated, driving the screw 5 to rotate. The lifting plate 6 moves upward on the rotating screw 5, through… The connecting block 7 drives the lifting ring 8 and the lifting plate 9 to move upward on the fixed cylinder 2. When the lifting plate 9 moves the core seat on the storage cylinder 10 to the first assembly plate 11, the driving rod 30 at one end of the through bar 24 slides in the second driving groove 33, which drives the driving frame 25 at one end of the through bar 24 to move away from the fixed cylinder 2. The second gear 26 drives the flipping frame 17 and the storage cylinder 10 to flip to a vertical position. Through the core assembly mechanism on the first assembly plate 11, the cores are simultaneously assembled on the core seats of multiple storage cylinders 10. In the assembly process, after assembly, the first motor 3 drives the screw 5 to move in the opposite direction, and the lifting plate 9 moves the storage cylinder 10 down to the second assembly plate 13. The driving rod 30 slides in the first driving groove 32, pulling the driving frame 25 towards the fixed cylinder 2, thereby causing the storage cylinder 10 to flip to an inclined state close to the second assembly plate 13. Through the core spring assembly mechanism on the second assembly plate 13, the core spring assembly work of multiple valve cores is performed simultaneously. Finally, the first motor 3 continues to drive the screw 5 to rotate, and the lifting plate 9 moves the assembled valve cores into the storage cylinder. After the valve core is placed in the storage slot 37 on the storage ring 36, the electric telescopic rod 18 is activated to drive the driving block 19 to move towards the flip frame 17, thereby releasing the valve core in the storage cylinder 10, so that the valve core can be smoothly inserted into the storage slot 37 for storage. After the lifting plate 9 moves up and resets, the second motor 39 is activated, which drives the storage ring 36 to rotate through the third gear 38 and the fourth gear 40, switching the storage ring 36 to the next storage slot 37 to the unloading position, and continuing to receive and store the assembled valve core. This makes the valve core storage more organized and easier to retrieve.

[0040] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
