[0002] In the field of tire production and related testing, visual acquisition of tires is of paramount importance. It can accurately acquire various characteristic information of tires, providing key data support for subsequent production, quality inspection and marking processes. To ensure the accuracy and efficiency of acquisition, it is usually necessary to use a robotic arm equipped with a camera for shooting and positioning.

[0003] Traditional tire vision acquisition equipment often has many shortcomings. Traditional tire vision acquisition robotic arms are usually equipped with only a single camera, which cannot simultaneously meet the needs of large-area positioning and high-precision positioning. Moreover, due to the influence of the working environment, the camera is easily contaminated with dust and other impurities, affecting the shooting effect and data accuracy. Therefore, a tire vision acquisition robotic arm is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a tire vision acquisition robotic arm for cleaning acquisition lenses in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A tire vision acquisition robotic arm includes a base and an articulated arm mounted on the base. One end of the articulated arm is rotatably mounted with a deflection seat, and a camera box is mounted on the deflection seat.

[0007] It also includes:

[0008] A switching motor is mounted on the camera housing;

[0009] A camera assembly, which is slidably mounted in a camera housing and moved by switching motors;

[0010] An air pump is installed in the camera housing. When the camera assembly is moved, the air pump is used to release air and clean the camera assembly.

[0011] As a further optimization of this utility model, the camera assembly includes two sliding seats. The sliding seats are slidably disposed in the camera box. Each sliding seat is provided with a hanging ear. A connecting rod is provided between the sliding seats. A first camera and a second camera are respectively disposed on the two sliding seats.

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1 - Figure 4 As shown, the tire vision acquisition robotic arm includes a base 1 and an articulated arm 2 mounted on the base 1. The articulated arm 2 provides the necessary flexibility and range of motion. One end of the articulated arm 2 is rotatably mounted with a deflector 3, and a camera box 4 is mounted on the deflector 3.

[0027] It also includes:

[0028] Switch motor 8, which is located on camera box 4;

[0029] Camera group 5 is slidably set in camera box 4. Camera group 5 is moved by switching motor 8. Camera box 4 is the mounting and moving platform of camera group 5.

[0030] Air pump 6 is located in camera box 4. When camera assembly 5 moves, air pump 6 is used to vent air and clean camera assembly 5.

[0031] The camera assembly 5 includes two sliding seats 51. The sliding seats 51 are slidably mounted in the camera housing 4. The sliding seats 51 are provided with hanging ears. A connecting rod 511 is provided between the sliding seats 51. The cameras are kept in a stable relative position by means of the connecting rod 511. A first camera 52 and a second camera 53 are respectively provided on the two sliding seats 51. A spring 54 is provided between the first camera 52 and the second camera 53 and the sliding seat 51. A protruding rod 55 is provided on both sides of the first camera 52 and the second camera 53.

[0032] The camera box 4 has V-shaped grooves 42 on both sides, and the protruding rods 55 are slidably disposed in the V-shaped grooves 42. The camera box 4 has a movable groove 41 on one side, and the hanging ear on the sliding seat 51 is slidably disposed in the movable groove 41. The camera has protruding rods 55 on both sides, so that the first camera 52 and the second camera 53 can slide in the V-shaped grooves 42 of the camera box, ensuring the stability of the camera movement.

[0033] The camera box 4 has brush plates 7 on both sides of its lower surface, and brush bristles 71 on the brush plates 7. The brush bristles 71 can contact the first camera 52 and the second camera 53.

[0034] Pistons 61 are provided on opposite sides of the two sliding seats 51. Pistons 61 can be embedded in air cylinders 6. Air nozzles 62 are provided on the brush plate 7. A conduit 63 is provided between the air nozzles 62 and the air cylinders 6.

[0035] The output end of the switching motor 8 is equipped with a lead screw 81, and the lug on the sliding seat 51 is threadedly connected to the lead screw 81. Therefore, when the motor rotates, the sliding seat 51 will slide in the camera box 4 to realize the switching of cameras.

[0036] It should be noted that when tire vision acquisition is required, the first camera 52 moves to the middle of the camera box 4 and uses its wide field of view shooting function to locate the marking frame. Then, the first camera 52 moves to the middle of the camera box 4 and executes the marking frame positioning program. After the approximate position of the marking frame is determined, the robot drives the articulated arm 2 to move the second camera 53 above the marking frame. The second camera 53 executes the marking frame precise positioning program, thereby completing the marking frame positioning work in the tire vision acquisition process.

[0037] During the switching process between the first camera 52 and the second camera 53, the switching motor 8 is activated, causing the lead screw 81 at its output end to rotate. Since the lugs on the sliding seats 51 in the camera assembly 5 are threadedly connected to the lead screw 81, the sliding seats 51 slide within the camera housing 4. The sliding seats 51 maintain a stable relative position through the connecting rods 511, and the protruding rods 55 on both sides slide within the V-grooves 42 of the camera housing 4. This causes the first camera 52 or the second camera 53 to shift downwards when it is in the middle position of the camera housing 4, preventing the brush plate 7 from obstructing the view. The lugs slide within the movable grooves 41, ensuring smooth movement. Simultaneously, the piston 61 on the opposite side of the sliding seat 51 is embedded in the air cylinder 6. The air cylinder 6 exhausts gas, which is ejected through the conduit 63 from the jet nozzle 62 on the brush plate 7. This cleans the first camera 52 and the second camera 53, which are respectively mounted on the two sliding seats 51. Furthermore, the bristles 71 on the brush plate 7 can also contact the cameras for further cleaning as the first camera 52 and the second camera 53 move.

[0038] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
