Description

Technical Field

[0001] The utility model relates to the technical field of wheel detection, in particular to a tire lifting and rotating mechanism. Background Art

[0002] With the widespread promotion and use of electric vehicles, the demand for electric vehicles has increased significantly. In the process of mass production of electric vehicles, there is a link in the assembly process that requires the detection of brand logos. This link requires the tire to be transported to a specified location and rotated to find the logo on the tire.

[0003] Since the markings on each tire are not uniformly placed during production and storage, the marking positions on batches of tires vary, and there is no ready-made equipment for easy identification. Currently, most processes in the industry use manual handling and manual rotation of tires to find the markings on the tires. However, this method requires a large external force to be applied to the tire. Even if the tire is rotated manually or with a robot clamp, it is necessary to continuously clamp and apply force to the tire to achieve rotation, which is laborious and inefficient. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a tire lifting and rotating mechanism with a reasonable structure, which limits the position of the detection part to remain unchanged. The tire can be driven to rotate when placed horizontally, and then the identification position can be detected, which makes the operation simpler and more efficient.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A tire lifting and rotating mechanism comprises a frame, on which a tire conveying line and a tire rotation detection station are sequentially arranged, and a limit position component and a sensor are arranged on the side of the tire rotation detection mechanism;

[0007] The tire rotation detection mechanism includes:

[0008] Motor, mounted on the frame,

[0009] The gear pair is driven by the motor.

[0010] The rotating bearing plate is driven by the output end of the gear pair; the tire to be tested is placed on the rotating bearing plate, limited by the limit assembly, and detected by the sensor.

[0011] As a further improvement of the above technical solution:

[0012] A positioning wheel is arranged on one side of the rotating bearing plate in the feeding direction, and a movable limiting wheel is arranged on the other side of the rotating bearing plate. The movable limiting wheel and the positioning wheel clamp and limit the tire to be detected.

[0013] The movable limiting wheel is driven by a push wheel cylinder installed on the frame, and the moving path of the movable limiting wheel is perpendicular to the conveying path of the tire to be tested.

[0014] The movable limiting wheels and the positioning wheels are symmetrically arranged on both sides of the tire rotation detection station, and the spacing between the movable limiting wheels and the positioning wheels on the same side is less than or equal to the diameter of the tire to be detected.

[0015] Flanges mounted on a frame are provided on both sides of the tire rotation detection station, and sensors are symmetrically mounted on the flanges; a rotational spacing is reserved between the tire to be detected and the flanges.

[0016] The tire conveying line comprises in sequence: a tire conveyor belt and a tire lifting mechanism. A tire pushing mechanism is correspondingly arranged above the tire lifting mechanism, and the tire pushing mechanism pushes the tire to be tested on the tire lifting mechanism forward.

[0017] The tire lifting mechanism comprises a lifting cylinder installed on a frame and a lifting bearing plate pushed by the lifting cylinder; the tire to be tested on the tire conveyor belt is lifted up when it moves to the lifting bearing plate.

[0018] The tire lifting mechanism is lifted upward to be coplanar with the rotating bearing plate of the tire rotation detection mechanism.

[0019] The tire pushing mechanism comprises a pushing cylinder and a pushing handle connected to the cylinder piston rod, the pushing handle is in contact with the tire to be tested; and the movement path of the pushing handle is higher than the lifting height of the tire lifting mechanism.

[0020] The tire pushing mechanism and the tire rotation detection station are arranged in a colinear manner and are arranged at an angle with the tire conveyor belt.

[0021] The beneficial effects of the utility model are as follows:

[0022] The tire lifting and rotating mechanism provided by the utility model can realize the automatic transmission and automatic rotation of the tire, replace the original operator, and solve the problems of manual error and backward production process. At the same time, the utility model is used in combination with other mechanisms and equipment, such as sensors and visual cameras, etc. The application scenarios are very wide and varied.

[0023] The tire conveying and rotating functions provided by the utility model are not limited to tire production lines, and can be applied to any rough surface parts in the shape of tires as long as they can have friction with the rotating carrier plate. It can also be applied to various production lines to achieve the functions of automatic conveying and rotation.

[0024] The utility model fully utilizes the advantageous characteristics of friction and can realize the requirements of product rotation at high speed, high efficiency and high stability.

[0025] In the specific structure, the utility model also arranges the two conveying structures on mutually perpendicular paths, thereby reducing the length space occupied by the equipment.

[0026] The two sets of wheels of the limiting assembly, since one set is a movable wheel, the spacing between adjacent wheels is set to be smaller than the diameter of the tire to be tested. The movable path of the movable limiting wheel can be used to clamp and limit tires of different sizes to be tested, preventing inertial displacement caused by lack of limit on the tire circumference, thereby further ensuring the accuracy of the test results.

[0038] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0039] like Figure 1-Figure 5As shown, the tire lifting and rotating mechanism of this embodiment includes a frame 1, on which a tire conveying line and a tire rotation detection station 5 are sequentially arranged, and a limit assembly 7 and a sensor 6 are arranged on the side of the tire rotation detection mechanism;

[0040] The tire rotation detection mechanism includes:

[0041] Motor 501 is mounted on frame 1.

[0042] Gear pair 502 is driven by motor 501.

[0043] The rotating carrier plate 503 is driven by the output end of the gear pair 502 ; the tire 8 to be tested is placed on the rotating carrier plate 503 , limited by the limiting assembly 7 , and detected by the sensor 6 .

[0044] A positioning wheel 701 is provided on one side of the rotating carrier plate 503 in the feeding direction, and a movable limiting wheel 702 is provided on the other side of the rotating carrier plate 503. The movable limiting wheel 702 and the positioning wheel 701 clamp and limit the tire 8 to be inspected.

[0045] The movable limiting wheel 702 is driven by a wheel pushing cylinder 703 installed on the frame 1, and the moving path of the movable limiting wheel 702 is perpendicular to the conveying path of the tire 8 to be tested.

[0046] The movable limiting wheels 702 and the positioning wheels 701 are symmetrically arranged on both sides of the tire rotation detection station 5, and the distance between the movable limiting wheels 702 and the positioning wheels 701 on the same side is less than or equal to the diameter of the tire 8 to be detected.

[0047] The tire rotation detection station 5 is provided with flanges 101 mounted on the frame 1 on both sides, and the sensor 6 is symmetrically mounted on the flanges 101 ; a rotational spacing is reserved between the tire 8 to be detected and the flanges 101 .

[0048] The tire conveying line includes in sequence: a tire conveyor belt 2, a tire lifting mechanism 3, a tire pushing mechanism 4 is correspondingly arranged above the tire lifting mechanism 3, and the tire pushing mechanism 4 pushes the tire 8 to be tested on the tire lifting mechanism 3 forward.

[0049] The tire lifting mechanism 3 includes a lifting cylinder 301 installed on the frame 1 and a lifting bearing plate 302 pushed by the lifting cylinder 301 ; the tire 8 to be tested on the tire conveyor belt 2 is lifted up when it moves onto the lifting bearing plate 302 .

[0050] The tire lifting mechanism 3 is lifted upward to be coplanar with the rotating bearing plate 503 of the tire rotation detection mechanism.

[0051] The tire pushing mechanism 4 includes a pushing cylinder 401 and a pushing handle 402 connected to the cylinder piston rod. The pushing handle 402 is in contact with the tire 8 to be tested. The movement path of the pushing handle 402 is higher than the lifting height of the tire lifting mechanism 3 .

[0052] The tire pushing mechanism 4 and the tire rotation detection station 5 are arranged in a colinear manner and are arranged at an angle with the tire conveyor belt 2 .

[0053] The specific structure and working principle of the utility model are as follows:

[0054] like Figure 1 The figure shows the overall structure of the utility model. The whole mechanism includes a tire conveyor belt 2 and a tire lifting mechanism 3 located at the output end of the tire conveyor belt 2. A tire pushing mechanism 4 is arranged directly above the tire lifting mechanism 3, and the pushing direction of the tire pushing mechanism 4 is perpendicular to the conveying direction on the tire conveyor belt 2. This turning design structure can reduce the space required for the equipment. A tire rotation detection station 5 is arranged on one side of the pushing direction of the tire pushing mechanism 4. The plane of the tire rotation detection station 5 is at the same height as the plane of the tire lifting mechanism 3 after lifting.

[0055] The tire conveyor belt 2 adopts a conventional conveyor belt, which only needs to be able to output the tire forward in a straight line.

[0056] like Figure 3 The figure shows a bottom view of the tire lifting mechanism 3 of the utility model. The tire lifting mechanism 3 includes a lifting cylinder 301 mounted on the frame 1, and the piston rod of the lifting cylinder 301 points vertically upward and is connected to a lifting bearing plate 302. In the initial state, the lifting bearing plate 302 is at the same height as the tire conveyor belt 2; when the tire needs to be lifted, the piston rod of the lifting cylinder 301 extends to lift the lifting bearing plate 302 carrying the tire 8 to be tested, and the tire is pushed to the tire rotation detection station 5 by the tire pushing device.

[0057] The tire pushing device includes a pushing cylinder 401 installed on the frame 1, and a pushing handle 402 is connected to the piston rod of the pushing cylinder 401. The side of the pushing handle 402 facing the tire 8 to be tested is a concave arc, so as to increase the contact area with the tire 8 to be tested and improve the pushing stability.

[0058] Combined with reference Figure 2 and Figure 4 A motor 501 is arranged below the tire rotation detection station 5, which drives a gear pair 502. The output end of the gear pair 502 is connected to a rotating bearing plate 503, and the tire 8 to be detected is placed on the rotating bearing plate 503.

[0059] In order to facilitate the positioning of the tire 8 to be tested, angle steel positioning and positioning components 7 are arranged around the rotating bearing plate 503. The angle steel is fixedly installed on the side of the tire rotation detection station 5 away from the push handle 402.

[0060] A positioning wheel 701 and a movable limiting wheel 702 are symmetrically arranged on both sides of the rotating bearing plate 503. The positioning wheel 701 and the movable limiting wheel 702 are both rotatable wheels, and the positioning wheel 701 is fixedly connected to the frame 1. The power source of the movable limiting wheel 702: the wheel pushing cylinder 703 is fixed on the frame 1, and pushes the movable limiting wheel 702 to reciprocate in a direction perpendicular to the tire output, allowing the tire 8 to be detected to pass through, or limiting the tire 8 to be detected.

[0061] When detection is required, the bottom motor 501 rotates, driving the gear pair 502, and the gear pair 502 drives the rotating bearing plate 503. There is friction between the rotating bearing plate 503 and the tire 8 to be detected, so the tire 8 to be detected rotates with the rotating bearing plate 503, and is limited by the limiting component 7 to ensure that displacement deviation is not likely to occur during the rotation process. The sensor 6 detects the mark during the rotation process.

[0062] The greatest advantage of the present invention is that, during the detection process, there is no need to introduce a large clamping force to drive the tire 8 to be detected to rotate, which reduces the intervention of equipment and makes the detection process more stable and accurate.

[0063] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
