[0002] In the electric vehicle manufacturing industry, the motor wheel is one of the core components, and its production efficiency and assembly precision directly affect the performance and quality of the entire vehicle.

[0003] The motor wheel is equipped with an air inlet for inflation. During automated assembly, the motor wheel needs to be placed in the correct position, meaning the air inlet needs to be positioned appropriately to facilitate subsequent assembly operations. However, traditionally, the handling and clamping of the motor wheel usually relies on manual operation or semi-automated equipment, resulting in inaccurate placement of the motor wheel and affecting production quality. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic conveying device for motor wheels, which can automatically identify and accurately grasp the air inlet of the motor wheel, facilitating subsequent motor wheel assembly.

[0005] The purpose of this utility model is achieved as follows:

[0006] An automatic conveying device for a motor wheel includes, in sequence, a flipping mechanism for keeping the motor wheel horizontal, a conveying mechanism for moving the motor wheel laterally, and a clamping mechanism.

[0007] The clamping mechanism includes a clamping bracket, on which a clamping conveyor belt and a straightening fixture located on both sides of the clamping conveyor belt are fixed. A clamping upright is fixed on the clamping bracket, and a transverse slide is fixed on the clamping upright. A clamping slide plate is slidably mounted on the transverse slide plate. A rotary fixture driven by a longitudinal cylinder and an industrial camera are respectively fixed on the clamping slide plate.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 4 :

[0032] An automatic conveying device for motor wheels includes, in sequence, a flipping mechanism 1 for keeping the motor wheels horizontal, a conveying mechanism 2 for moving the motor wheels laterally, and a clamping mechanism 3.

[0033] The clamping mechanism 3 includes a clamping bracket 30, on which a clamping conveyor belt 31 and a straightening fixture 32 located on both sides of the clamping conveyor belt 31 are fixed. A clamping stand 33 is fixed on the clamping bracket 30, and a transverse slide 34 is fixed on the clamping stand 33. A clamping slide plate 340 is slidably mounted on the transverse slide 34. A rotating fixture 35 driven by a longitudinal cylinder and an industrial camera 36 are respectively fixed on the clamping slide plate 340. When the clamping slide plate 340 slides to one end of the transverse slide 34, the industrial camera 36 is located above the middle of the straightening fixture 32.

[0034] like Figure 5 As shown in the figure, this figure shows the position of the air inlet 40 on the motor wheel 4.

[0035] During implementation, the motor wheel is placed in the flipping mechanism, which horizontally positions it. The horizontally positioned motor wheel is then conveyed by the conveyor mechanism 2 until it reaches the clamping conveyor belt 31 in the clamping mechanism. An industrial camera 36 photographs and identifies the position of the motor wheel's air inlet. After obtaining the signal, the rotating fixture 35 is rotated to the required angle to clamp the motor wheel. The final placement of the clamped motor wheel meets the requirements for subsequent processing, significantly improving production and assembly efficiency.

[0036] Preferably, the rotary clamp 35 includes a clamping connecting plate 350 fixed to the output end of the longitudinal cylinder, a longitudinally arranged rotary cylinder 351 fixed on the clamping connecting plate 350, a rotary clamping seat 352 fixed on the output end of the rotary cylinder 351, and a plurality of clamping arms 353 driven by the cylinder fixed at the bottom of the rotary clamping seat 352.

[0037] The rotary clamp 35 moves up and down via a longitudinal cylinder. During industrial camera recognition, the rotary clamp 35 remains at the top. After recognition, it moves upward above the motor wheel via a transverse slide 34 and then downward via a longitudinal cylinder. The bottom of the rotary clamp 352 opens several clamping arms 353 via cylinder drive, thus gripping the motor wheel. The rotary clamp 35 has a simple overall structure, is easy to drive with cylinders, and improves gripping efficiency.

[0038] Preferably, a camera mount 360 is fixed to one end of the clamping slide 340, and the industrial camera 36 is located in the middle of the camera mount 360. The industrial camera 36 is placed vertically and positioned in the middle of the camera mount 360. The camera mount 360 has a plate-like structure, and a shooting hole for the industrial camera 366 is provided in the middle of the camera mount 360. The independent fixed camera mount 360 allows for detachable connection of the industrial camera, facilitating the placement of cameras of different sizes and providing better stability.

[0039] Preferably, the correction clamp 32 includes a support plate 320 slidably mounted on the clamping bracket 30, and two sets of opposing nylon pads 321 are fixed at the inner end of the support plate 320, and the inner side of the nylon pads 321 is provided with a guide surface 322 that abuts against the outer wall of the motor wheel.

[0040] In the above structure, the two sets of nylon pads 321 on each set of support plates 320 are detachable, and the detachment method is a plug-in structure. The guide surfaces 322 of the two sets of nylon pads form a certain included angle, which clamps the side wall of the motor wheel, thereby firmly fixing the motor wheel and enabling the industrial camera to accurately identify it, providing accuracy for subsequent clamping.

[0041] Preferably, a synchronous rack 323 is fixed to the rear end of the support plate 320, and a synchronous gear is provided between the two synchronous racks 323. When the synchronous gear rotates, the two support plates 320 move closer or further apart.

[0042] During implementation, the two synchronous racks 323 are arranged vertically, and the synchronous gears rotate between the two synchronous gears to move the support plates 320 at both ends closer or further apart. This synchronous movement allows the motor wheel to avoid being pushed in the opposite direction by a support plate on one side, thus enabling a larger displacement range.

[0043] Preferably, the end of the clamping conveyor belt 31 is provided with a positioning support rod 37 fixed to the clamping bracket 30.

[0044] During the process of clamping the conveyor belt 31 and conveying the motor wheel, the positioning support rod 37 can prevent excessive movement to the end, allowing the positioning support rod 37 to clamp accurately and ensuring normal clamping operation.

[0045] Preferably, the flipping mechanism 1 includes a flipping platform 10, a gripper cylinder mounting plate 11 is movably hinged on the flipping platform 10, a motor wheel clamping plate assembly 12 driven by a cylinder is provided on the gripper cylinder mounting plate 11, a flipping cylinder 13 is hinged on the flipping platform 10, and the output end of the flipping cylinder 13 drives the gripper cylinder mounting plate 11 to rotate hingedly along the hinge point.

[0046] It is worth mentioning that the flipping mechanism 1 is not only for placing the motor wheel horizontally, but also for determining the orientation of the motor wheel by checking whether the motor wheel clamping plate assembly 12 is clamped. After normal clamping, the flipping cylinder 13 drives the rotation of the gripper cylinder mounting plate 11, allowing the motor wheel to be transported to the conveying mechanism in a horizontal state.

[0047] Preferably, the conveying mechanism 2 includes a conveying support 20 located between the flipping mechanism 1 and the clamping mechanism 3. A conveyor belt 21 extending along the length of the conveying support 20 is provided on the conveying support 20, and conveying baffles 22 located on both sides above the conveyor belt 21 are provided on both sides of the conveying support 20. The conveying baffles 22 can prevent the motor wheels from falling off the side due to accumulation.

[0048] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
