Detailed Implementation

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 9 :

[0042] A fully automated tire loading and inflation device for the front wheel of an electric vehicle includes a wheel hub assembly device 1, an automatic tire feeding device 2, an automatic pressing and inflation device 3, and an automatic clamping device 4.

[0043] The hub assembly device 1 includes a hub input roller mechanism 11 and a hub output roller mechanism 12 located below the hub grabbing truss 10. A hub conveying mechanism 13 is provided on one side of the hub grabbing truss 10, and a hub positioning and moving mechanism 14 is provided at the end of the hub conveying mechanism 13.

[0044] The automatic tire feeding device 2 includes a tire input roller mechanism 21 and a tire output roller mechanism 22 located below the tire gripping truss 20. A tire conveying mechanism 23 is provided on one side of the tire gripping truss 20, facing the hub conveying mechanism 13. A tire flipping mechanism 24 is provided at the end of the tire conveying mechanism 23.

[0045] The automatic press-fit inflation device 3 includes a turntable 30, on which a plurality of clamp groups 31 for fixing the wheel hub are evenly distributed in the circumferential direction, and an inflation mechanism 32 is arranged in the longitudinal direction on the turntable 30.

[0046] The automatic gripping device 4 includes an assembly frame 40 and a dual-station moving gripping mechanism 41 for gripping tire assemblies on the turntable 30.

[0047] like Figure 1 As shown, when the equipment is in operation, the wheel hub assembly device 1 continuously feeds the wheel hubs, and at the same time, the disc brake disc is effectively installed during the feeding process, and finally the wheel hub with the disc brake disc installed is placed on the turntable 30.

[0048] During synchronous operation, the automatic tire feeding device 2 continuously clamps the tires and flips them in the correct direction, so that the tires falling onto the turntable 30 can be correctly assembled.

[0049] Furthermore, the turntable 3 in the automatic pressing and inflation device 3 can rotate. Pressing is performed, and after pressing, the inflation mechanism 32 is used for effective inflation to complete the tire assembly.

[0050] After final assembly, the tire assembly is picked up by the automatic gripping device 4 and sent to the assembly rack 40, thus completing the entire automated assembly production.

[0051] Preferably, the hub input roller mechanism 11 includes several horizontally placed parallel input rollers 110, and the two sides of the input rollers 110 are driven by drive motors driving sprockets. An input tray 111 is slidably arranged above the input rollers 110, and several layers of hub groups are stacked on the input tray 111. A partition is arranged between each hub group. The hub output roller mechanism 12 at the top of the input tray 111 includes an output roller 120 parallel to the input rollers 110 in the hub input roller mechanism 11. An output tray 121 is slidably arranged on the output roller 120, and the partition is stacked on the output tray 121.

[0052] Preferably, the hub gripping gantry 10 includes a three-way sliding hub robotic arm 100, with a hub gripper 101 at the bottom of the hub robotic arm 100. The hub conveying mechanism 13 includes two sets of synchronous conveyor belts 130 driven by servo motors. The hub positioning and moving mechanism 14 includes a hub positioning frame 140 located at the ends of the two sets of synchronous conveyor belts 130. A hub clamp 141 that slides relatively on the hub positioning frame 140 is provided on the hub positioning frame 140. A hub straightening clamp 142 located between the two hub clamps 141 is provided on the hub positioning frame 140. An industrial camera for detection is provided on one side of the hub straightening clamp 142. A disc brake assembly turntable 15 is provided on one side of the hub positioning and moving mechanism 14.

[0053] like Figure 2 and Figure 3 As shown, the above structure is the main component of the wheel hub assembly device 1. The input roller is used for transporting and adjusting the position of the input pallet. The input roller 110 adopts the width of two sets of input pallets and forms an opening at the entrance of the input roller to facilitate manual loading or AGV loading. Located on the output roller side, it is mainly used for stacking the partitions for placing wheel hubs.

[0054] The wheel hub robotic arm further clamps the wheel hub and transports it via conveyor mechanism 13. The wheel hub positioning and moving mechanism determines and corrects the wheel hub's orientation. Simultaneously, before tire assembly, the valve stem position on the wheel hub needs to be located for accurate tire assembly. An industrial camera is used to determine the valve stem position, and after determination, the disc brake disc is effectively assembled in the disc brake assembly frame 15, thus completing the installation of the wheel hub assembly.

[0055] In the above structure, the disc brake assembly frame 15 includes a designated turntable on one side, on which disc brake discs are placed circumferentially, approximately 200 in number, which can be placed manually or by a feeding machine; it further includes a locking mechanism on one side, which bolts the output disc brake discs to the continuously feeding wheel hubs on the designated turntables. During the locking process, an industrial camera is used for effective identification, so that the disc brake discs can be accurately installed at the end of the wheel hub.

[0056] Preferably, both the tire input roller mechanism 21 and the tire output roller mechanism 22 include several parallel idlers. The automatic tire feeding device 2 includes a tire gripping truss 20. A three-way sliding tire robotic arm is provided on the tire conveying truss 230, and an internally supported tire gripping mechanism 25 is provided at the bottom of the tire robotic arm.

[0057] like Figure 4 As shown, in the above structure, the tire conveying truss 230 is equipped with corresponding slide rails, which enable the tire robotic arm to be effectively driven by a motor.

[0058] Preferably, the internal support tire gripping mechanism 25 includes an internal support panel 250. A plurality of wide pneumatic grippers 251 are fixed to the bottom of the internal support panel 250, and each wide pneumatic gripper 251 has a strut seat 252 at both ends. An internal strut 253 is fixed to the bottom of the strut seat 252. A connecting plate 254 is fixed to the top of the internal support panel 250. A sliding plate 255 is slidably mounted above the connecting plate 254 via a plurality of guide rods. A standard cylinder is fixed on the sliding plate 255 to drive the sliding plate 255 to move up and down toward the connecting plate 254. The sliding plate 255 and... An adjusting plate 256 is provided between the connecting plates 254, which slides up and down along several guide rods. The bottom of the adjusting plate 256 is fixed with a pressure plate 257 corresponding to several wide pneumatic grippers 251. The bottom of the sliding plate 255 is fixed with a swing fixing seat 258. The bottom of the swing fixing seat 258 is hinged with a swing rod 2580. Both ends of the swing rod 2580 are provided with swing bearings. The bottom of the adjusting plate 256 and the top of the connecting plate 254 are respectively fixed with an upper bearing guide rail groove and a lower bearing guide rail groove that are adapted to the swing bearings at both ends of the swing rod 2580.

[0059] Preferably, a lead screw is provided in the middle of the inner support panel 250, and the two ends of the lead screw are respectively provided with mounting threads in different directions. There are three sets of wide air grippers 251. The top of the middle wide air gripper is sleeved in the middle of the lead screw, and the tops of the two wide air grippers are threaded to the mounting threads on both sides of the lead screw through screw holes. A hand-tightening wheel coaxial with the lead screw is provided on the side wall of the inner support panel 250. When the hand-tightening wheel is driven to rotate, the two outer wide air grippers move towards or away from each other.

[0060] like Figure 5 and Figure 6 As shown, in the above structure, tires are typically stacked, one tire at a time. During the gripping process, individual tires need to be gripped for loading. The output end of the standard cylinder drives the connecting plate up and down. When the connecting plate moves downward, the wide grippers drive the inner support rods on both sides to clamp the stacked tires in an internal support manner. The standard cylinder drives the connecting plate to move upward, which in turn raises the bottom of the swing rod. The upper end of the swing rod then moves downward, further driving the adjusting plate 256 to move downward, ultimately causing the pressure plate to move downward. During the downward pressure, the clamped tires may fall off. The tires squeezed out by the pressure plate will eventually be clamped onto a single tire, completing the transportation of an individual tire.

[0061] Furthermore, a three-clamp structure is adopted to improve assembly efficiency; and a hand-twisting wheel is used for adjustment, so as to adapt to tires with different gears for internal support clamping operations.

[0062] Preferably, the tire flipping mechanism 24 includes a tire flipping frame 240, on which an industrial identification camera and a tire flipping clamp 241 composed of a vertical cylinder and a swing cylinder are mounted.

[0063] like Figure 7 As shown, the tire has a front and a back side. During transportation, an industrial identification camera identifies the tire sidewall. After identification, a vertical cylinder drives the tire flipping clamp 241 downward to clamp the tire, and then a swing cylinder flips it over, facilitating subsequent tire installation.

[0064] Preferably, the clamp assembly 31 includes a plurality of hub fixing frames 310 fixed on the turntable 30, a tire side frame 311 located on one side of the hub fixing frame 310 fixed on the turntable 30, and a pressing mechanism 33 located on one side of the inflation mechanism 32 is provided on the turntable 30.

[0065] The wheel hub mounting brackets 310 consist of six sets, evenly distributed circumferentially on the upper surface of the turntable. A ring frame is located in the center of the turntable, and the tire sidewall brackets 311 are inserted into the ring frame. The tire sidewall brackets 311 consist of two inclined tire positioning rods, on which the tire rests. The pressing mechanism 33 is used to press the tire against the wheel hub and perform the pressing assembly. The tire is further inflated by the inflation mechanism.

[0066] The inflation mechanism uses an inflation hood for inflation, which is efficient and uniform.

[0067] Preferably, the assembly frame 40 includes an assembly stand 400, one side of which is provided with a plurality of inclined assembly slots 401, and the other side of which is provided with a plurality of inlet ports 402 communicating with the assembly slots 401. The assembly stand 400 is equipped with an assembly gripper 403 for gripping the tire assembly.

[0068] like Figure 8 and Figure 9 As shown, the assembly stand 400 is equipped with assembly grippers 403 for gripping the tire assembly. The tire assembly is placed into the slot 402 and stacked in an inclined assembly slot. To achieve the inclination setting or adjustment of the inclination of the assembly slot, cylinders with lifting functions are installed at the ends of several assembly slots.

[0069] Preferably, the dual-station moving gripping mechanism 41 includes two sets of parallel gripping slide rails 411 fixed on the gripping base plate 410. An assembly support frame 412 is slidably mounted on the gripping slide rails 411. The gripping base plate 410 has symmetrical side sliding grooves 413 located on both sides of the two gripping slide rails 411. A sliding clamp 414 that slides back and forth is provided on the assembly support frame 412. When the assembly support frame 412 slides along the gripping slide rails 411, the sliding clamp 414 swings along the sliding groove direction of the side sliding groove 413.

[0070] Furthermore, the two sets of assembly slots mentioned above, in conjunction with the dual-station moving gripping mechanism 41, enable the separate assembly of the two sets of assembly slots. In actual operation, the assembly stand's assembly grippers grasp the tire assembly on the turntable and place it on the two sliding clamps 414 respectively.

[0071] The above embodiments are merely 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.
