Description

Technical Field

[0001] The utility model relates to the technical field of tire cord fabric forming detection, and more specifically to a cord fabric forming detection device of a tire carcass high-efficiency forming machine. Background Art

[0002] High-efficiency forming machine cord fabric forming test refers to the process of forming and quality testing the cord fabric using a high-efficiency forming machine during the cord fabric production process. Test items: Test items include peeling force, flame retardancy, oil resistance, composition, color fastness, wire break analysis, air content, aging resistance, tear strength, light transmittance, adhesion, etc. Through testing, the quality of the cord fabric can be ensured, the quality of tire manufacturing can be improved, and the operating reliability of the machine can be guaranteed.

[0003] However, during the inspection process of tire cord molding on domestic high-efficiency molding machines, most of the operators rely on the naked eye to identify the fit of the air-tight layer, cord and buffer layer on the tire molding cylinder, and manual identification is far from meeting the high-quality requirements of existing tire factories. It is difficult to identify molding problems such as tire molding, missing adhesion, unconnected air-tight layer / cord joints, flash seams, folded joints, and large and small joints. In addition, manual inspection is inefficient and uncontrollable, which can easily cause defective products to flow into the next process. In addition, when there is no need for daily inspection, the camera's inspection probe is easily exposed to the outside world for a long time, which easily accumulates a lot of dust, affecting the clarity of the inspection image, resulting in the need to clean the inspection probe during each inspection. Therefore, this scheme proposes a tire carcass high-efficiency molding machine cord molding inspection device. Utility Model Content

[0004] Technical issues to be solved:

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a tire carcass efficient forming machine cord forming detection device, which uses camera detection instead of manual visual identification to avoid problems such as airtight layer / cord joints not being connected, flash seams, folded joints, missing joints, and joint oversizes during the tire forming process. After an abnormality is detected, the equipment automatically shuts down to reduce manual operation. At the same time, when no inspection is needed on a daily basis, the two cameras can be stored. While protecting the camera probe, the surface of the machine head can also be protected to avoid dust adhesion.

[0006] Technical solution:

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A tire carcass high-efficiency forming machine cord forming detection device comprises a carcass drum main unit, the output end of which is fixedly connected to a drum main shaft, the outer end of which is sleeved with a forming cylinder, a support seat is provided at the bottom side of the drum main shaft, and a 3D point cloud image forming component is installed at the upper end of the support seat, wherein;

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0032] See also Figure 1-4 , a tire carcass high-efficiency forming machine cord forming detection device, comprising a carcass drum main unit 1, the output end of the carcass drum main unit 1 is fixedly connected to a drum main shaft 2, the outer end of the drum main shaft 2 is sleeved with a forming cylinder 3, the bottom side of the drum main shaft 2 is provided with a support seat 4, and the upper end of the support seat 4 is installed with a 3D point cloud image forming component 5, wherein;

[0033] The 3D point cloud image forming component 5 includes a box body 51 fixedly connected to the upper end of the support seat 4, an integrated camera 1 52 is movably installed between the inner walls of one side of the box body 51, and an integrated camera 2 53 is fixedly connected between the inner walls of the other side of the box body 51.

[0034] During use, the present solution aims at the problems of missing stickers, airtight layer / cord joints not being connected, flashing seams, joint folding, joint size differences, etc., which are difficult to be identified by human eyes in the prior art. In the present embodiment, camera detection is used to replace human eyes to identify, thereby avoiding the problems of airtight layer / cord joints not being connected, flashing seams, joint folding, missing stickers, joint size differences, etc., which occur during the tire molding process. After detecting an abnormality, the equipment automatically stops, thereby reducing manual operation.

[0035] During the rapid rotation of the forming cylinder, the tire cord installed on its surface rotates synchronously. At this time, after two cameras are installed at different angles, the tire cord is scanned under the angle detection formed by the two ray surfaces to generate a 3D point cloud image. At this time, the 3D point cloud image generates different colors according to the fitting status of the airtight layer / cord layer / buffer layer of the cord. Finally, it is compared with the color of the finished cord product according to the existing standard to identify whether the tire cord has problems such as the airtight layer / cord joint not connected, flash seams, folded joints, missing joints, large and small joints, etc., so as to eliminate the above-mentioned undesirable phenomena generated during the tire carcass forming process.

[0036] In this embodiment, when a camera is used to detect the rotation speed of the forming cylinder, an encoder is also provided inside the drum main shaft 2 and is associated with the camera.

[0037] See also Figure 2-4 An arc groove 54 is provided at the side end of the box body 51, and a transmission shaft 55 is slidably connected between the inner walls of the arc groove 54, and one end of the transmission shaft 55 is fixedly connected to the top side of the integrated camera 52. A motor 56 is also installed at the side end of the box body 51, and the motor 56 is located directly below the arc groove 54. The output end of the motor 56 passes through the inside of the box body 51 and is fixedly connected to the center side of the integrated camera 52. The other side end of the box body 51 is rotatably connected to a cover plate 531, and the cover plate 531 is located on one side of the integrated camera 53.

[0038] More specifically, a plurality of evenly distributed angle marking lines 57 are engraved on the side of the box body 51 . The angle marking lines 57 are located on the upper side of the arc groove 54 , and the angle between each scale is set to 10°.

[0039] During use of this solution, the detection angle of the integrated camera 52 can be finely adjusted according to the different sizes of the forming tube 3. When the outer diameter of the forming tube 3 is large or small, the output end thereof can be driven to rotate by controlling the motor 56. Since the bottom side of the integrated camera 52 is connected with a transmission shaft 55, and the transmission shaft 55 is located inside the arc groove 54, the flipping position of the integrated camera 52 is limited, thereby controlling the integrated camera 52 connected thereto to rotate at an angle.

[0040] Meanwhile, in the present embodiment, the driving system of the motor 56 is uniformly controlled by the PLC program, so that the flip angle of the integrated camera 52 controlled by the motor 56 can be accurately controlled, and under the setting of the angle marking line 57, the deflection angle of the integrated camera 52 can be automatically determined according to the position of the transmission shaft 55, so that the rays detected by the integrated camera 52 can be accurately projected onto the surface of the forming tube 3, which is conducive to timely fine-tuning;

[0041] In addition, in the present embodiment, the internal structure of the integrated camera 52 is provided with a telescopic device. During the detection process, the probe of the integrated camera 52 can be telescoped to above the top surface of the box body 51 to increase the detection range.

[0042] See also Figure 3-4 A detection port 511 is provided at the upper end of the box body 51, a storage groove 512 is provided on the rear side wall of the detection port 511, and a cover plate 513 is slidably connected between the inner walls of the storage groove 512.

[0043] More specifically, a second detection port 514 is provided at the front end of the box body 51 , a second storage slot 515 is provided on the side wall of the second detection port 514 , and a third cover plate 516 is slidably connected between the inner walls of the second storage slot 515 .

[0044] During the use of this solution, when there is no need to perform detection operations, the integrated camera 1 52 can be reset to the initial state, and the cover plate 2 513 can be pulled out from the inside of the storage slot 1 512 to completely close the top surface of the box body 51, and the cover plate 3 516 can be pulled out from the inside of the storage slot 2 515 to close the front side of the box body 51 to prevent a large amount of dust from floating into the box body 51 when not in use, and from adhering to the surface of the probe of the integrated camera 1 52 to cause unclearness. The integrated camera 2 53 on the other side can be covered by flipping the cover plate 1 531, so that the integrated camera 1 52 and the integrated camera 2 53 can be protected when not in use in daily life;

[0045] Subsequently, according to the rotation direction of the integrated camera 1 52 , the corresponding sliding cover plate 2 513 and cover plate 3 516 can be used to form a phenomenon of storing on one side and closing on the other side, thereby reducing the intake of dust while not affecting the detection range of the integrated camera 1 52 .

[0046] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
