Description

[0001] This invention relates to the field of tire mold defect detection, and in particular to a multi-size adjustable tire mold detection device. Background Technology

[0002] During the tire vulcanization process, tire molds inevitably accumulate contaminants, requiring regular disassembly and cleaning. After cleaning and reassembly, bumps or assembly defects are inevitable. Furthermore, the characters in the tire molds are mirror images, making character defects difficult to detect. Typically, tire mold inspection devices are used to photograph and inspect the tire molds for defects.

[0003] Currently, in the process of tire mold defect detection, due to the wide variety of tire mold models and sizes, tire molds can only be inspected using tire mold inspection devices that correspond to their size. Furthermore, during tire production, it is necessary to inspect tire molds of different sizes for defects, making the inspection process complex and cumbersome. It is impossible for a single inspection device to meet the defect inspection needs of different tire mold models. The technical problems of current tire mold inspection devices include: inability to adapt to the inspection needs of tire molds of different sizes, unstable operation, and large size, making it difficult to meet the ever-increasing demand.

[0004] To overcome these problems, the present invention provides a multi-size adjustable tire mold inspection device, which has the advantages of adjustable size, stable operation, and modular structural design. Summary of the Invention

The lead screw I and lead screw II are threadedly connected to the lead screw nut. The flange ring of the lead screw nut is fixedly connected to the slider I by bolts. The threads of the lead screw I and lead screw II have opposite directions of rotation, respectively driving the two sliders I to reciprocate in opposite directions. The slider I is fixedly connected to the slider II. The side end of the slider I is fixedly connected to the tension wheel connector by bolts. The tension wheel connector and the rubber-coated tension wheel are statically connected via a positioning wheel shaft, driving the rubber-coated tension wheel to reciprocate in reciprocating motion.

[0009] Preferably, the rotating module includes: a rotating base, a cylindrical gear I, a motor bracket II, a reducer, a rotary motor, a connecting ring, a cylindrical gear ring, an H-groove bearing, and a bearing bracket; the rotary motor and the reducer are connected via a flange, the reducer and the motor bracket II are fixedly connected via bolts, the reducer and the cylindrical gear I are connected circumferentially via a key, and axially positioned via a shaft end retaining ring and screws, driving the cylindrical gear I to rotate; the cylindrical gear I internally meshes with the cylindrical gear ring, the cylindrical gear ring is positioned by the H-groove bearing, the H-groove bearing and the bearing bracket are connected via a bearing mounting shaft, the bearing mounting shaft and the bearing bracket are fixedly connected via bolts, the top end of the cylindrical gear ring is fixedly connected to the connecting ring via bolts, and the connecting ring and the rotating base are fixedly connected via a bolt group, thereby driving the rotating base to rotate.

Each set of the rotating roller and the roller shaft are connected by a deep groove ball bearing, and there are four sets in total. The roller shaft and the rotating base are fixedly connected by bolts. When the rotating base rotates, the rotating roller contacts the annular surface of the tire mold base. As the rotating base rotates, the rotating roller rolls on the annular surface of the tire mold base, thereby increasing stability.

[0011] Preferably, the lifting column module includes: a lead screw bearing housing, a lead screw III, a trapezoidal nut, a coupling II, a lifting motor, a limit block II, a slider III, a column, and a column support; the lifting motor is connected to the lead screw III via the coupling II, the bottom end of the lead screw III is connected to the lead screw bearing housing via a thrust ball bearing, the lead screw bearing housing is fixedly connected to the column by bolts, the column is fixedly connected to the column support and the limit block II by bolts, the slider III is fixedly connected to the trapezoidal nut by bolts, the trapezoidal nut is threadedly connected to the lead screw III, and the trapezoidal nut is fixedly connected to the detection length adjustment module by bolts; the lifting motor drives the lead screw III to rotate, thereby driving the trapezoidal nut and the detection length adjustment module to rise and fall.

[0012] Preferably, the detection length adjustment module includes a synchronous belt drive pulley, a detection length adjustment module motor, a motor bracket III, a slider IV, a slider V, a detection length adjustment module intermediate moving plate, a pulley mounting plate, a synchronous belt driven pulley, a belt clamp I, a detection length adjustment module moving plate, a synchronous belt, a belt clamp II, and a detection length adjustment module base; the top of the slider IV is fixedly connected to the detection length adjustment module intermediate moving plate by bolts, and the detection length adjustment module intermediate moving plate is fixedly connected to the motor bracket III, the pulley mounting plate, and the guide rail by bolts. Frame III is bolted to the detection length adjustment module motor. The detection length adjustment module motor is keyed to the synchronous belt drive pulley, driving the synchronous belt drive pulley to rotate. The synchronous belt drive pulley engages the synchronous belt, and the other end of the synchronous belt engages the synchronous belt driven pulley, causing the synchronous belt driven pulley to rotate. The synchronous belt driven pulley is connected to the pulley mounting plate via an inertial wheel axle. Slider V is bolted to the detection length adjustment module moving plate. The detection length adjustment module moving plate is fixedly connected to the belt clamp II. Clamp II is fixedly connected to the synchronous belt. The synchronous belt drives the belt clamp II and the detection length adjustment module moving plate to move. The synchronous belt is fixedly connected to the belt clamp I, and the belt clamp I is fixedly connected to the detection length adjustment module base by bolts. During the synchronous belt transmission, the belt clamp II and the upper belt are transmitted back and forth. Since the belt clamp I is fixedly connected to the detection length adjustment module base, the lower belt of the synchronous belt cannot be transmitted back and forth. When the upper belt of the synchronous belt is transmitted forward, the tension force generated by the synchronous belt drives the synchronous belt drive wheel to move horizontally forward, thereby driving the detection length adjustment module motor and the detection length adjustment module intermediate moving plate to move horizontally forward. The movement stroke of the detection length adjustment module intermediate moving plate is half of the movement stroke of the detection length adjustment module moving plate. When the upper belt of the synchronous belt is transmitted backward, the tension force generated by the synchronous belt drives the synchronous belt driven wheel to move horizontally backward, thereby driving the detection length adjustment module motor and the detection length adjustment module intermediate moving plate to move horizontally backward.

[0014] Compared with existing tire mold inspection devices, the present invention provides a multi-size adjustable tire mold inspection device, which has the following advantages:

[0015] 1. This invention includes a tensioning module. The tire mold base has a ring-shaped structure. By controlling a telescopic motor, the position of the rubber-coated tensioning wheel can be automatically adjusted to ensure it is in fixed contact with the inner tangential surface of the tire mold base ring, thus providing positioning and fixation. The rubber-coated tensioning wheel has good elasticity and shock absorption properties, effectively absorbing vibrations and impacts generated during operation. This prevents vibrations during the operation of the tire mold inspection device, thereby making the device more stable.

[0016] 2. This invention is provided with lead screws I and II of the same specifications but with opposite thread directions. The worm gear is fixedly connected to the lead screws I and II with opposite threads on both sides by flanges. The rotation of the worm gear drives the lead screws I and II to rotate, which can drive the two sliders I and the tensioning wheel connecting parts to reciprocate and extend by the same stroke, which can make the movement of the tensioning module more stable and reduce impact and vibration.

[0017] 3. The present invention is provided with an H-groove bearing. The bearing inside the groove of the H-groove bearing is in close contact with the outer wall of the cylindrical gear ring. The bearing groove clamps and squeezes the outer end face of the cylindrical gear ring, which plays a limiting role in the cylindrical gear ring, thereby ensuring the stable rotation of the cylindrical gear ring and the rotating module.

[0018] 4. This invention is equipped with a rotating module, with four sets of rotating rollers and roller shafts deployed around the rotating base. The rotating rollers are in contact with the upper end face of the tire mold base ring, which can play a supporting role. The rotation of the rotating module can make the rotating base drive the rotating rollers to roll smoothly on the upper end face of the tire mold base ring, thereby making the lifting column module and the detection length adjustment module fixed on the rotating module more stable when rotating, ensuring the stability of the camera module rotation, and thus improving the detection accuracy of the tire mold.

[0019] 5. This invention is equipped with a lifting column module and a detection length adjustment module. A motor drives a ball screw to rotate, which in turn raises and lowers the screw nut and the detection length adjustment module. This controls the height of the detection length adjustment module. Simultaneously, the detection length adjustment module, driven by a motor and a synchronous belt, moves its moving plate and its fixedly connected camera module horizontally. Through lifting and horizontal movement, the camera module's posture can be precisely adjusted, allowing for flexible control to meet the detection posture requirements of tire molds of different sizes. This enables the tire mold detection device to be size adjustable, satisfying the defect detection needs of different tire mold models.

[0020] 6. The detection length adjustment module of the present invention fixes the upper and lower belt clamps of the timing belt to the detection length adjustment module moving plate and the detection length adjustment module base respectively, and the detection length adjustment module motor is fixedly connected to the detection length adjustment module middle moving plate. This allows the detection length adjustment module to move horizontally while the detection length adjustment module moving plate moves horizontally, thereby realizing dual-stroke detection length adjustment of the camera module. This can meet the detection needs of some large-sized tire molds, and the dual-stroke detection length adjustment structure can reduce the volume of the tire mold detection device.

The tensioning module 1 is tightened and secured to the tire mold, serving a positioning and clamping function to ensure the overall stability of the device. The rotating module 2 is fixedly connected to the protective cover 3, which prevents dust, sand, and other fine particles from entering the machine. The rotating module 2 is fixedly connected to the lifting column module 4 by bolts, and rotating the rotating module 2 drives the lifting column module 4 to rotate. The lifting column module 4 is connected to the inspection length adjustment module 5 by bolts, enabling the inspection length adjustment module 5 to move up and down. The inspection length adjustment module 5 is fixedly connected to the camera module 6 by bolts. The rotating module 2 drives the lifting column module 4 to rotate, the lifting column module 4 drives the inspection length adjustment module 5 to move up and down, and the inspection length adjustment module 5 drives the camera module 6 to move horizontally, allowing the camera module 6 to take pictures.

[0033] like Figure 2As shown, the tensioning module 1 includes: tensioning motor 11, coupling I 12, worm gear 13, worm wheel 14, slider I 15, lead screw I 16, limit block I 17, slider II 18, rubber-coated tensioning wheel 19, tensioning module base 110, tensioning wheel connector 111, lead screw nut 112, lead screw II 113, and motor bracket I 114. The tensioning motor 11 is fixedly connected to the motor bracket I 114 by bolts, and the motor bracket I 114 is fixedly connected to the tensioning module base 110 by bolts; the tensioning motor 11 is connected to the coupling I 12 by a key, and the coupling I 12 is circumferentially connected to the worm gear 13 by a key, and the tensioning motor 11 drives the worm gear 13; the worm gear 13 is connected to the bearing housing by a deep groove ball bearing, and the bearing housing is fixedly connected to the tensioning module base 110 by bolts, and the worm gear 13 meshes with the worm wheel 14; the worm wheel 14 is positioned by the limit block I 17 to ensure that the position of the worm wheel 14 does not shift when rotating; the two sides of the worm wheel 14 are fixedly connected to the lead screw I 16 and the lead screw II 113 by flanges, driving the lead screw I 16 and the lead screw II 113 to rotate; the lead screw I 16 and lead screw II 113 are connected to lead screw nut 112 by threads. The flange ring of lead screw nut 112 is fixedly connected to slider I 15 by bolts. The threads of lead screw I 16 and lead screw II 113 have opposite directions of rotation, which respectively drive the two sliders I 15 to reciprocate in opposite directions. Slider I 15 is fixedly connected to slider II 18. The side end of slider I 15 is fixedly connected to the tension wheel connector 111 by bolts. The tension wheel connector 111 and the rubber-coated tension wheel 19 are statically connected through the positioning wheel shaft, which drives the rubber-coated tension wheel 19 to reciprocate in reciprocating movement, so that the rubber-coated tension wheel 19 is tightly fitted with the annular sectional surface of the tire mold base plate, preventing the tire mold detection device from shaking during operation and ensuring the stability of the tire mold detection device.

[0034] like Figure 3 , Figure 4 and Figure 5As shown, the rotating module 2 includes: a rotating base 21, a cylindrical gear I 22, a motor bracket II 23, a reducer 24, a rotary motor 25, a connecting ring 26, a cylindrical gear ring 27, an H-groove bearing 28, and a bearing bracket 29. The rotating base 21 includes rotating rollers 211 and roller shafts 212. Each set of rotating rollers 211 and roller shafts 212 is connected by a deep groove ball bearing, with a total of four sets. The roller shafts 212 and rotating base 21 are fixedly connected by bolts. When the rotating base 21 rotates, the rotating rollers 211 contact the upper end face of the tire mold base ring. As the rotating base 21 rotates, the rotating rollers 211 roll on the upper end face of the tire mold base ring, thereby increasing stability. The rotary motor 25 and reducer 24 are connected by a flange. The reducer 24 and motor bracket II 23 are fixedly connected by bolts. The reducer 25 and cylindrical gear ring 26 are connected by a connecting ring 27, a cylindrical gear ring 28, an H-groove bearing 29. Wheel I 22 is connected circumferentially by a key and axially positioned by a retaining ring and screws at the shaft end, driving the cylindrical gear I 22 to rotate. The cylindrical gear I 22 meshes with the cylindrical gear ring 27. The cylindrical gear ring 27 is positioned by an H-groove bearing 28, which prevents the cylindrical gear ring 27 from shifting position during rotation, ensuring stable rotation. The H-groove bearing 28 is connected to the bearing bracket 29 by a bearing mounting shaft, which is bolted to the bearing bracket 29. The top of the cylindrical gear ring 27 is bolted to the connecting ring 26. The connecting ring 26 is bolted to the rotating base 21. The rotating base 21 is bolted to the protective cover 3. The rotary motor 25 drives the cylindrical gear I 22 to rotate, which in turn drives the cylindrical gear ring 27 to rotate, thereby driving the connecting ring 26 and the rotating base 21 to rotate, enabling the lifting column module 4, which is fixedly connected to the rotating base 21, to rotate stably.

[0035] like Figure 6 As shown, the lifting column module 4 includes: a lead screw bearing seat 41, a lead screw III 42, a trapezoidal nut 43, a coupling II 44, a lifting motor 45, a limit block II 46, a slider III 47, a column 48, and a column support 49. The lifting motor 45 is connected to the lead screw III 42 via the coupling II 44; the bottom end of the lead screw II 42 is connected to the lead screw bearing seat 41 via a thrust ball bearing; the lead screw bearing seat 41 is fixedly connected to the column 48 by bolts; the column 48 is fixedly connected to the column support 49 and the limit block II 46 by bolts; the slider III 47 is fixedly connected to the trapezoidal nut 43 by bolts; the trapezoidal nut 43 is threadedly connected to the lead screw III 42; and the trapezoidal nut 43 is fixedly connected to the detection length adjustment module 5 by bolts. The lifting motor 45 drives the lead screw III 42 to rotate, thereby raising and lowering the trapezoidal nut 43 and the detection length adjustment module 5, which can control the height of the detection length adjustment module 5 to meet the detection height requirements of tire molds of different sizes and models.

[0036] like Figure 7 and Figure 8 As shown, the detection length adjustment module 5 includes a synchronous belt drive pulley 51, a detection length adjustment module motor 52, a motor bracket Ⅲ 53, a slider Ⅳ 54, a slider Ⅴ 55, a detection length adjustment module intermediate moving plate 56, a pulley mounting plate 57, a synchronous belt driven pulley 58, a belt clamp Ⅰ 59, a detection length adjustment module moving plate 510, a synchronous belt 511, a belt clamp Ⅱ 512, and a detection length adjustment module base 513. The top of slider IV 54 is bolted to the middle moving plate 56 of the detection length adjustment module. The middle moving plate 56 of the detection length adjustment module is bolted to the motor bracket III 53, the pulley mounting plate 57, and the guide rail. The motor bracket III 53 is bolted to the motor 52 of the detection length adjustment module. The motor 52 of the detection length adjustment module is keyed to the synchronous belt drive pulley 51, driving the synchronous belt drive pulley 51 to rotate. The synchronous belt drive pulley 51 engages with the synchronous belt 511, and the other end of the synchronous belt 511 engages with the synchronous belt driven pulley 58, driving the synchronous belt driven pulley 58 to rotate. The moving wheel 58 is connected to the pulley mounting plate 57 via an inertial wheel axle; the slider V 55 is fixedly connected to the detection length adjustment module moving plate 510 via bolts, the detection length adjustment module moving plate 510 is fixedly connected to the belt clamp II 512, the belt clamp II 512 is fixedly connected to the synchronous belt 511, and the synchronous belt 511 drives the belt clamp II 512 and the detection length adjustment module moving plate 510 to move; the synchronous belt 511 is fixedly connected to the belt clamp I 59, and the belt clamp I 59 is fixedly connected to the detection length adjustment module base 513 via bolts; during the synchronous belt transmission process, the belt clamp II 512 and the upper belt are transmitted back and forth, by... The detection length adjustment module base 513 is fixedly connected to belt clamp I 59. The lower synchronous belt cannot transmit forward or backward. When the upper synchronous belt transmits forward, the tension force generated by the synchronous belt drives the synchronous belt drive pulley 51 to move horizontally forward, thereby driving the detection length adjustment module motor 52 and the detection length adjustment module intermediate moving plate 56 to move horizontally forward. The travel distance of the detection length adjustment module intermediate moving plate 56 is half the travel distance of the detection length adjustment module moving plate 510. When the upper synchronous belt transmits backward, the tension force generated by the synchronous belt drives the synchronous belt driven pulley 58 to move horizontally backward. The detection length adjustment module motor 52 and the detection length adjustment module intermediate moving plate 56 move horizontally backward. The moving stroke of the detection length adjustment module intermediate moving plate 56 is half the stroke of the detection length adjustment module moving plate 510. Therefore, only one detection length adjustment module motor 52 is needed to enable the detection length adjustment module moving plate 510 to achieve double the horizontal stroke, realizing dual-stroke detection length adjustment of the camera module. This can meet the detection needs of tire molds of different sizes, and the dual-stroke detection length adjustment structure can reduce the size of the tire mold detection device.

The 3D profilometer 61 and the profilometer mounting plate 67 are fixedly connected by bolts. The industrial camera 62 is connected and secured to the profilometer mounting plate 67 via the camera mounting plate 66. The laser displacement sensor 64 is connected and secured to the profilometer mounting plate 67 via the sensor bracket 65. The position of the camera module 6 can be adjusted according to the result displayed by the laser displacement sensor 64 to verify whether the position of the camera module 6 meets the requirements for tire mold inspection. The light source 63 is fixedly connected to the profilometer mounting plate 67 via bolts and can provide necessary lighting in scenes with low natural light.
