Description

Technical Field

[0001] This invention relates to a testing device, specifically a tire character 3D testing device. Background Technology

[0002] In current tire production, tires are pressed using different molds. The characters on the tire are also generated simultaneously during the pressing process using the molds, and the characters imprinted by different molds are not exactly the same. The characters on a tire mainly consist of several parts: tire brand, tire specifications, technical parameters, production date and certification marks, as well as other special markings. For manufacturers, the specification number is an important parameter for production and quality management; for vehicle assembly plants, it is an important criterion for determining whether tires have been incorrectly shipped or installed; and for users, it is an important reference for tire selection. Therefore, ensuring the accuracy of the characters on the tire surface is of great significance in both production and assembly. Currently, character inspection in tire production mainly relies on manual visual confirmation, which is not only inefficient but also prone to errors due to operator fatigue.

The top of the support platform 2 has a rotatable turntable 4, and the bottom of the support platform 2 has a first drive mechanism 5 that drives the turntable 4 to rotate. Above the turntable 4 is a worktable 6 connected to it. Specifically, the turntable 4 and the worktable 6 are connected by multiple vertical rods 7. The worktable 6 has multiple movable slots 8 and multiple clamping rods 9 evenly distributed on it. Each clamping rod 9 corresponds to a movable slot 8 and is located within it. Below the worktable 6 is a second drive mechanism 10 that drives the multiple clamping rods 9 to clamp or open synchronously. The top of the housing 1 has a 3D laser sensor 11 that can move back and forth and rise and fall.

[0023] Reference Figure 3 and Figure 4 The first driving mechanism 5 includes a drive motor 51, a reducer 52, a main gear 53, and a driven gear 54. The reducer 52 is connected to the bottom of the support platform 2. The output shaft of the drive motor 51 is connected to the input end of the reducer 52. The output shaft of the reducer 52 passes through the top of the support platform 2 and connects to the main gear 53. The main gear 53 and the driven gear 54 mesh. The main gear 53 is connected to the bottom of the turntable 4. The drive motor 51 is a servo motor. The drive motor 51 drives the main gear 53 to rotate through the reducer 52. The main gear 53 then drives the turntable 4 and the worktable 6 to rotate through the driven gear 54.

[0024] Reference Figure 4 The bottom of the support platform 2 is connected to a support base 12, and a first bearing seat 13 is connected to the support base 12. A bearing 14 is connected to the top of the first bearing seat 13. A rotating shaft 15 is connected to the middle of the bottom surface of the driven gear 54. The first bearing seat 13 has a shaft hole (not shown in the figure) communicating with the bearing 14. The lower part of the rotating shaft 15 passes through the bearing 14 and then enters the shaft hole (not shown in the figure). The rotating shaft 15 is designed so that the driven gear 54 can rotate around the rotating shaft 15 when rotating, ensuring that the driven gear 54 rotates more smoothly.

[0025] Refer to 4 to Figure 6The second drive mechanism 10 includes an electric push rod 16, three connecting blocks 17, three connecting rods 18, and a triangular linkage plate 19. The three connecting blocks 17 are arranged in a triangle and each corresponds to one corner of the triangular linkage plate 19. The three connecting rods 18 are also arranged in a triangle and each is located on one side of the triangular linkage plate 19. The electric push rod 16 is connected to one of the connecting blocks 17. One end of each connecting rod 18 corresponds to one corner of the triangular linkage plate 19 and is hinged to that corner. The other end of each connecting rod 18 corresponds to a connecting block 17 and is hinged to the top of one end of that connecting block 17. The bottom of the worktable 6 is connected to three slide rails 20. Each slide rail 20 corresponds to one connecting block 17. The top of the other end of each connecting block 17 is connected to a slider 21. The slider 21 slides with the slide rail 20. There are three clamping rods 9. Each clamping rod 9 corresponds to one connecting block 17 and is connected to the center of the top surface of the connecting block 17. There are three corresponding movable through slots 8.

[0026] Refer to 4 to Figure 6 The triangular linkage plate 19 includes an upper triangular plate 191 and a lower triangular plate 192. The triangles of the upper triangular plate 191 and the lower triangular plate 192 are connected by a pin 193. One end of each connecting rod 18 is located between a corner of the upper triangular plate 191 and a corner of the lower triangular plate 192 and is hinged to the pin 193. A second bearing seat 194 is connected between the middle of the upper triangular plate 191 and the middle of the lower triangular plate 192. A planar pressure bearing 195 is provided between the top surface of the second bearing seat 194 and the bottom surface of the worktable 6. Two symmetrical self-aligning roller bearings 196 are provided inside the second bearing seat 194. A central shaft 22 is connected to the middle of the worktable 6. The central shaft 22 passes through the planar pressure bearing 195 and the two self-aligning roller bearings 196. A locking nut 23 is provided at the bottom of the central shaft 22.

[0027] Refer to 4 to Figure 6 The electric push rod 16 is used to move one of the connecting blocks 17. When the electric push rod 16 extends, one of the connecting blocks 17 moves outward. At the same time, driven by the three connecting rods 18, the triangular linkage plate 19 rotates clockwise and the other two connecting blocks 17 also move outward, ultimately causing the three clamping rods 9 to open synchronously. Conversely, when the electric push rod 16 retracts, one of the connecting blocks 17 moves inward. At the same time, driven by the three connecting rods 18, the triangular linkage plate 19 rotates counterclockwise and the other two connecting blocks 17 also move inward, ultimately causing the three clamping rods 9 to clamp synchronously. The planar pressure bearing 195 bears the axial load of the worktable 6, and the two self-aligning roller bearings 196 bear the radial load of the worktable 6.

[0028] Reference Figure 3The top of the workbench 6 is evenly distributed with multiple support rods 24. Each support rod 24 has two sets of placement slots 25 along its length. Each set of placement slots 25 consists of multiple spaced placement slots 25, and each placement slot 25 is equipped with a bullseye caster 26. The multiple support rods 24 are used to place tires. The bullseye caster 26 ensures that the tires are aligned when clamped. Because tires have high friction, without the bullseye caster 26, even if the tires are deformed when clamped, they will not be aligned. At the same time, the bullseye caster 26 can also reduce the friction between the tires and the multiple support rods 24 when clamped. Specifically, there are six support rods 24.

[0029] Reference Figure 1 , Figure 2 and Figure 7 The top of the housing 1 is provided with a mounting opening 27, and a mounting plate 28 is connected to the mounting opening 27. The mounting plate 28 has a strip-shaped movable hole 29. A first linear slide module 30 is horizontally arranged on the bottom surface of the mounting plate 28 along the front-back direction. The slide of the first linear slide module 30 is located at the bottom of the first linear slide module 30. The slide of the first linear slide module 30 is connected to a first mounting bracket 31. A second linear slide module 32 is vertically arranged on the left side of the first mounting bracket 31. The slide of the second linear slide module 32 is located on the left side of the second linear slide module 32. The slide of the second linear slide module 32 is connected to a second mounting bracket 33. The 3D laser sensor 11 is connected to the bottom of the second mounting bracket 33. The second linear slide module 32 is located in the strip-shaped movable hole 29. A cover 34 is provided on the top surface of the mounting plate 28. The first linear slide module 30 is used to drive the second linear slide module 32 and the 3D laser sensor 11 to move back and forth. The second linear slide module 32 is used to drive the 3D laser sensor 11 to move up and down. The first linear slide module 30 and the second linear slide module 32 are existing structures, and their specific structures will not be described in detail here. A display device 35 is connected to one side of the housing 1. The display device 35 is used to display the detection results of the tire characters.

[0030] Reference Figures 1 to 7The design principle of this invention is as follows: A tire is placed on multiple support rods 24 of the workbench 6. The second drive mechanism 10 drives three clamping rods 9 to clamp the tire. The 3D laser sensor 11 moves forward to above the side of the tire and descends to prepare for scanning and image acquisition. Then, the first drive mechanism 5 drives the turntable 4 and the workbench 6 to rotate. The 3D laser sensor 11 acquires the image as the tire rotates. After the tire completes one rotation, the 3D laser sensor 11 finishes acquiring the image. After the 3D laser sensor 11 has acquired the image, it can transmit the image to the recognition device for automatic recognition. After the recognition device completes the recognition, it transmits the recognition result to the display device 35. The communication between the 3D laser sensor 11 and the display device 35 and the recognition device is existing technology and will not be described in detail here. The recognition device is only used to assist in describing the working principle of this invention and is not within the scope of the description of the structure of this invention. The recognition method of the recognition device is a conventional technical means in this field and will not be described in detail here.

[0031] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
