Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire detection, and more specifically, to a tire side plate character detection device. Background Art
[0002] At present, tire factories need to manually replace the tire side panel character blocks in the early stage of vulcanization, and the engraved characters are reverse characters, which are easy to confuse. Even if the finished tires can be manually inspected in the later stage, the side panels have been loaded into the vulcanizer and a considerable period of time has passed. Therefore, a more accurate and stable automatic detection technology is needed to assist manual inspection. However, because the side panels are too large and heavy, loading and unloading the side panels and controlling the position stability are both difficult. Using an assembly line will take up a lot of space and the transportation safety is difficult to control. If the side panels are placed directly on the ground for inspection, the detection accuracy of the equipment is difficult to guarantee. Traditional 2D photography cannot rely on stable brightness to distinguish the characters and dirt and rust on the side panels. The field of view of structured light is inversely proportional to the resolution. Stitching and imaging are inefficient and cumbersome. The accuracy of overall imaging is difficult to meet the requirements. Utility Model Content

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] like Figures 1 to 6 As shown, the utility model provides a tire side plate character detection device, comprising:
[0029] A housing 1, a top plate 3 is fixedly mounted on the upper side of the housing 1, and a wheel 10 is fixedly mounted on the lower side of the housing 1;
[0030] A scanning mechanism, which is arranged below the top plate 3;
[0031] A placing mechanism, which is arranged inside the housing 1;
[0032] Wherein, the scanning mechanism includes a robot 8;
[0033] A crossbeam 4 is fixedly installed below the top plate 3, a mounting seat 5 is fixedly installed below the crossbeam 4, a base 6 is fixedly installed below the mounting seat 5, a rotation sensor 7 is fixedly sleeved on the outer side of the base 6, a robot 8 is fixedly installed below the base 6, and a scanner 9 is fixedly installed below the robot 8.
[0034] The frames of the cart 26, the platform 11 and the clamping block 16 are staggered and complementary to each other, so that the side plate 28 can be stably controlled inside the equipment, as well as the subsequent clamping and centering, which not only supports efficient transportation but also ensures the accuracy of detection; the clamping block 16 controls the movement speed and stop of the motor 17 through the contact photoelectric sensor 1 23 and the contact photoelectric sensor 2 24. The contact photoelectric sensor 2 24 determines the initial contact between the fixed roller and the mold to prepare for deceleration. The contact photoelectric sensor 1 23 determines the degree of clamping according to the extrusion of the deformation spring 22, and automatically and accurately fixes the side plate 28 in the center from the outside to the inside; to deal with molds of different sizes, the system can guide the action according to the real-time contour image feedback from the rotation sensor 7, and automatically filter out useless edges and platform 11 images, and accurately locate the content area of the side plate 28.
[0035] With minimal hardware cost and space occupied, the large-mass side panels 28 can be easily transported and inspected, and the loss of the conveying tool has little impact on the overall use, and it is easy to replace. Multiple carts 26 can be used alternately to improve efficiency; the loading method of the inspection station is simple, and it can adapt to the centering of side panels 28 of different sizes, with safe operation and high efficiency; the collaborative robot 8 is used with a 3D line laser sensor for scanning, and the operation process is simple and efficient, and a sufficiently high acquisition accuracy is guaranteed.
[0036] Wherein, the placement mechanism includes a carrier 11;
[0037] The carrier 11 is movably connected to the inside of the shell 1, and a motor 14 is fixedly installed on the inner side of both ends of the shell 1. A lifting rod 15 extending to the outside of the carrier 11 is fixedly installed below the motor 14, and balls 12 are evenly fixedly installed above the carrier 11.
[0038] In order to achieve safe connection of the side panel 28 between the trolley 26 and the platform 11, a staggered frame structure can be designed so that the trolley 26 can be completely embedded in the equipment, and then the motor 14 is driven to lift the platform 11 to lift the side panel 28 away from the surface of the trolley 26. At this time, the influence of the trolley 26 on the accuracy of the mechanism is zero.
[0039] Among them, a motor 17 is fixedly installed at the bottom of the platform 11, a rotating shaft 18 is rotatably installed at the left end of the platform 11, the rotating shaft 18 is connected to the motor 17 through a track 19, a placement block 21 is fixedly installed above the platform 11, a long shaft 20 is fixedly installed on the inner side of the rotating shaft 18, and the long shaft 20 is fixedly connected to the outer side of the placement block 21.
[0040] The motor 17 rotates to drive the rotating shaft 18 to rotate through the crawler belt 19, so that the platform 13 moves inward around the long axis 20 for clamping.
[0041] Among them, the outer side of the long axis 20 is movably sleeved with a platform 13, the bottom of the platform 13 is fixedly installed with a vertical block 25, the inner sides of the vertical block 25 are elastically installed with a deformation spring 22, and the lower part of the platform 13 is fixedly installed with a contact photoelectric sensor 23 located on the outer side of the deformation spring 22.
[0042] The side plates 28 are large or small, and the distance that the motor 17 moves each time is not fixed. In order to prevent the baffle 27 from being over-extruded and causing failure, an automatic stop mechanism is required. By adding a deformation spring 22 at the clamping position, the extrusion force can be inferred, and the action will only stop when both ends are clamped at the same time. In order to improve the efficiency of the action, a contact photoelectric sensor 23 can be used as a judgment mark for the slowing of the clamping speed.
[0043] The trolley 26 is also included. A plastic pad 29 is evenly fixedly installed on the top of the trolley 26 . A baffle 27 is fixedly installed on the top of the plastic pad 29 . A brake pedal 30 is fixedly installed on the bottom of the trolley 26 .
[0044] It is more convenient to use an independent movable cart 26. A plastic pad 29 is laid on the cart 26 to prevent the side panels 28 from being damaged during loading and unloading. A circle of baffles 27 are designed on the periphery to prevent the side panels 28 from falling. A brake pedal 30 is provided underneath to prevent the cart from slipping when stationary.
[0045] The trolley 26 further includes a side panel 28 , which is located above the trolley 26 and corresponds to the baffle 27 .
[0046] The center of the side plate 28 and the rotation center of the upper robot 8 should remain vertical, that is, the side plate 28 needs to be centered each time.
[0047] A contact photoelectric sensor 24 is fixedly installed below the platform 13 , and a clamping block 16 is evenly fixedly installed above the platform 13 .
[0048] Ball bearings need to be laid on the carrier 11 so that the side plate 28 can be easily pushed. In order to ensure the accuracy of the center position, using a motor will be more accurate than a cylinder.
[0049] A double-opening window door 2 is movably mounted on the outer side of the housing 1 , and a handle 31 is fixedly mounted on the outer side of the double-opening window door 2 .
[0050] There are potential safety hazards during the rotation of the robot 8, so a protective device needs to be designed. In order to isolate external dust and facilitate internal maintenance at the same time, it is most appropriate to use a double-opening window door equipped with safety photoelectrics.
[0051] The working principle and use process of this utility model:
[0052] The frames of the cart 26, the platform 11 and the clamping block 16 are staggered and complementary to each other, so that the side plate 28 can be stably controlled inside the equipment, as well as the subsequent clamping and centering, which not only supports efficient transportation but also ensures the accuracy of detection; the clamping block 16 controls the movement speed and stop of the motor 17 through the contact photoelectric sensor 1 23 and the contact photoelectric sensor 2 24. The contact photoelectric sensor 2 24 determines the initial contact between the fixed roller and the mold to prepare for deceleration. The contact photoelectric sensor 1 23 determines the degree of clamping according to the extrusion of the deformation spring 22, and automatically and accurately fixes the side plate 28 in the center from the outside to the inside; to deal with molds of different sizes, the system can guide the action according to the real-time contour image feedback from the rotation sensor 7, and automatically filter out useless edges and platform 11 images, and accurately locate the content area of the side plate 28.
