[0001] The utility model relates to the technical field of tire tread detection, in particular to a tire tread detection device for tire embryo pattern grooving. Background Art

[0002] Before grooving the tire embryo, it is necessary to detect the tread of the tire embryo. During the tire production process, various defects such as uneven tread, cracks or burns may occur on the tread. The quality of the tire tread has a great impact on the overall quality of the tire, which may cause vehicle driving noise and even pose a risk of tire explosion in severe cases.

[0003] The existing patent CN 220525667 U is a tire surface detection device. By inserting the hub on the tire body into the gap between the limit blocks, the limiting effect on the tire body is achieved. By screwing the cover plate to the surface of the limit blocks, the clamping and fixing effect on the tire body is achieved. By driving the rotating shaft by the motor, the rotating plate drives the tire body to rotate in front of the image collector. The surface of the tire body can be evenly irradiated and collected by the image collector, enabling personnel not to always watch and operate beside the detection device, thus reducing the working intensity of the staff.

[0004] However, during the use of the existing patent tire surface detection device, the device fixes the tire by positioning the hub on the tire through the limit blocks. However, for a tire embryo without a mounted hub, it cannot be positioned. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a tire tread detection device for tire embryo pattern grooving, which solves the problem that the aforementioned device fixes the tire by positioning the hub on the tire through the limit blocks, but for a tire embryo without a mounted hub, it cannot be positioned.

[0006] To achieve the above purpose, the utility model provides a tire tread detection device for tire embryo pattern grooving, including a detection base, a mounting frame and an image collector. The mounting frame is fixedly installed on the detection base, and the image collector is fixedly installed on the mounting frame. It further includes a positioning device. The positioning device includes a positioning mounting plate, a fixing rod, a positioning rod, a rotating ring and a locking component. There is an installation groove on one side of the detection base, and a receiving groove is also provided on the side of the detection base close to the installation groove. The receiving groove penetrates the installation groove. The positioning mounting plate is rotatably installed on the detection base and is located in the receiving groove. The fixing rod is fixedly installed on the positioning mounting plate. The rotating ring is rotatably installed on the fixing rod. The positioning rod is fixedly installed on the rotating ring. The locking component is installed on the fixing rod.

[0008] Among them, the positioning device further includes a positioning block. The positioning block is fixedly installed on the positioning rod and is located at one end of the positioning rod away from the rotating ring.

[0009] Among them, the positioning device further includes a rotating component. The rotating component includes a rotating shaft, a first gear, and a driving member. The rotating shaft is rotatably installed on the detection base and is located in the installation groove. At the same time, the rotating shaft is fixedly connected to the positioning mounting plate; the first gear is fixedly installed on the rotating shaft; the driving member drives the first gear to rotate.

[0010] Among them, the driving member includes a second gear and a motor. The motor is fixedly installed on the detection base and is located in the installation groove; the second gear is fixedly installed on the motor and meshes with the first gear.

[0011] When using a tire tread detection device for embryo pattern grooving of the present utility model, place the embryo on the detection base and make the fixed rod pass through the embryo. Then rotate the positioning rod so that the positioning rod rotates around the fixed rod under the rotational cooperation of the rotating ring and the fixed rod until the end of the positioning rod abuts against the inner wall of the embryo. Then rotate the rotating rod to drive the locking ring to rotate, so that the locking ring moves downward along the fixed rod through the threaded cooperation with the fixed rod until the locking ring abuts against the rotating ring and fixes the rotating ring. At this time, the positioning rod is also fixed, and under the action of the three groups of positioning rods, the embryo is fixed.

[0018] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model.

[0019] The first embodiment of this application is as follows:

[0020] Please refer to Figures 1-3 , Figure 1 It is a schematic diagram of the overall structure of a tire tread detection device for embryo pattern grooving according to the first embodiment of the present utility model, Figure 2 It is a schematic connection diagram of the detection base and the positioning mounting plate in the first embodiment of the present utility model, Figure 3 It is a schematic connection diagram of the fixed rod and the rotating ring in the first embodiment of the present utility model.

[0021] The present utility model provides a tire tread detection device for embryo pattern grooving: including a detection base 101, a mounting frame 102 and an image acquisition device 103, and further including a positioning device. The positioning device includes a positioning mounting plate 104, a fixed rod 105, a positioning rod 106, a rotating ring 107 and a locking component. The locking component includes a locking ring 110 and a rotating rod 111. The positioning device further includes a positioning block 112. Through the foregoing solution, the problem that the previous device fixed the tire by positioning the hub on the tire through a limiting block, but for an embryo without a mounted hub, it could not be positioned, is solved. It can be understood that this solution can also be used to solve the problem of the automatic rotation of the positioning mounting plate.

[0022] In this embodiment, the fixed effect on the embryo is achieved by the abutment of the ends of the three groups of the positioning rods 106 against the inner walls of each orientation of the embryo.

[0023] Among them, an installation groove 108 is provided on one side of the detection base 101, and a receiving groove 109 is further provided on the side of the detection base 101 close to the installation groove 108. The receiving groove 109 penetrates through the installation groove 108. The positioning and installation plate 104 is rotatably installed on the detection base 101 and is located in the receiving groove 109. The fixing rod 105 is fixedly installed on the positioning and installation plate 104. The rotating ring 107 is rotatably installed on the fixing rod 105. The positioning rod 106 is fixedly installed on the rotating ring 107. The locking component is installed on the fixing rod 105. The image acquisition device 103 is communicatively connected to the image processing system. When the image processing system receives the image collected by the image acquisition device 103 and analyzes and compares the image, it can quickly detect the defects on the surface of the tire embryo. The installation groove 108 is square-shaped, the receiving groove 109 is circular-shaped, the positioning and installation plate 104 is in a disc-shaped structure. The number of the fixing rods 105 is three groups, and they are annularly distributed on the upper surface of the positioning and installation plate 104. Each group of the fixing rods 105 is provided with a group of the positioning rods 106, a group of the rotating rings 107 and a group of the locking components. The positioning rod 106 is welded to the rotating ring 107. During use, rotate the three groups of the positioning rods 106, so that the positioning rods 106 rotate around the fixing rods 105 under the rotational cooperation of the rotating rings 107 and the fixing rods 105, and the ends of the positioning rods 106 are abutted against the inner wall of the tire embryo. Then, lock the positions of the positioning rods 106 through the locking components. Thus, through the abutment of the ends of the three groups of the positioning rods 106 against the inner walls of all directions of the tire embryo, the fixing effect on the tire embryo is realized.

[0024] Secondly, the locking ring 110 is threadedly connected to the fixing rod 105; the rotating rod 111 is fixedly installed on the locking ring 110. The locking ring 110 is in a ring-shaped structure, and the inner wall of the locking ring 110 is provided with threads. Three groups of the rotating rods 111 are annularly distributed on the outer wall of each group of the locking rings 110. The end of the rotating rod 111 is in a spherical structure, and the rotating rod 111 is welded to the locking ring 110. During use, rotate the rotating rod 111 to drive the locking ring 110 to rotate. The locking ring 110 moves downward along the fixing rod 105 through the threaded cooperation with the fixing rod 105 until it abuts against the rotating ring 107, so that the rotating ring 107 is fixed, and further the positioning rod 106 is fixed, thereby realizing the locking of the positioning rod 106.

[0025] Again, the positioning block 112 is fixedly installed on the positioning rod 106 and is located at one end of the positioning rod 106 away from the rotating ring 107. The number of the positioning blocks 112 is three groups, and they are distributed at the end positions of each group of the positioning rods 106. The positioning block 112 is made of rubber material, which can prevent the positioning rod 106 from damaging the embryo during fixation.

[0026] In this embodiment, during use, place the embryo on the detection base 101, and make the fixing rod 105 pass through the embryo. Then rotate the positioning rod 106, so that the positioning rod 106 rotates around the fixing rod 105 under the rotational cooperation of the rotating ring 107 and the fixing rod 105 until the end of the positioning rod 106 abuts against the inner wall of the embryo. Then rotate the rotating rod 111 to drive the locking ring 110 to rotate, so that the locking ring 110 moves downward along the fixing rod 105 through the threaded cooperation with the fixing rod 105 until the locking ring 110 abuts against the rotating ring 107 and fixes the rotating ring 107. At this time, the positioning rod 106 is also fixed. Under the action of the three groups of positioning rods 106, the embryo is fixed. Then, through the rotational cooperation between the positioning mounting plate 104 and the detection base 101, drive the embryo to rotate, so that the image acquisition device 103 performs a full - range detection on the tread of the embryo. Thus, through the abutment of the ends of the three groups of positioning rods 106 against the inner walls of all directions of the embryo, the fixing effect of the embryo is realized.

[0030] Among them, the rotating shaft 201 is rotatably installed on the detection base 101 and is located in the installation groove 108. At the same time, the rotating shaft 201 is fixedly connected to the positioning and installation plate 104; the first gear 202 is fixedly installed on the rotating shaft 201; the driving member drives the first gear 202 to rotate.

The second gear 203 drives the first gear 202 to rotate through meshing with the first gear 202, thereby realizing the rotation effect of the first gear 202.

[0032] In this embodiment, during use, the motor 204 is started to drive the second gear 203 to rotate.
