Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tire quality detection, especially relates to a tire quality detection device. BACKGROUND

[0002] Tires are assembled on various vehicles or machines in the form of circular elastic rubber products, which mainly realize the normal driving of vehicles through the contact with the ground. The tires are usually installed on metal rims, which not only can support the weight of the vehicle body and effectively buffer various impacts from the outside, but also are an important basis for ensuring the driving performance of the vehicle.

[0003] Before the tire is delivered, its quality needs to be detected, and the staff needs to conduct a circumferential detection on the surface of the tire, which aims to timely detect and prevent the occurrence of adverse conditions such as damage. However, in the traditional detection mode, the usual operation process is that the staff first properly fixes the tire, and then manually rotates the tire to check each part of the tire. This method has many drawbacks. If the detection state is to be maintained continuously, the staff must continuously rotate the tire, which undoubtedly increases the work intensity of the staff and makes them prone to fatigue during the long detection process. At the same time, the way of fixing the tire is often complicated and requires the staff to spend more time and effort. Considering the above factors, the work efficiency is ultimately reduced. SUMMARY

[0004] The utility model aims at solving the technical problem that the staff needs to continuously rotate the tire in the detection state, which increases the work intensity of the staff. The utility model provides a tire quality detection device, the clamping table can rotate relative to the operation table with the gravity direction as the axial direction, and the automatic rotation process replaces the complicated operation of manually rotating the tire by the staff in the traditional detection mode, thereby reducing the labor intensity of the staff.

[0005] To solve the above technical problems, the embodiment of the utility model discloses a tire quality detection device, which comprises:

[0006] An operation table;

[0007] A clamping table is arranged on the operation table, and the clamping table can rotate relative to the operation table with the gravity direction as the axial direction. The clamping table comprises:

[0008] An annular part is arranged on the outer surface of the clamping table in the circumferential direction, and the annular part is movably connected with the inner wall of the operation table.

[0009] A plurality of first clamping portions are protruded from the clamping table along the gravity direction, and are arranged at intervals along the circumferential direction, and are used for fixing the outer wall of the tire;

[0010] A fixing seat is arranged at intervals with the first clamping portion along the horizontal direction to form a tire placing cavity;

[0011] A second clamping portion is protruded from the fixing seat, and is used for fixing the inner wall of the tire.

[0012] According to the above technical scheme, before the tire detection work is performed, the staff first places the tire to be detected in the tire placing cavity. At this time, the plurality of first clamping portions fix the outer wall of the tire, and the second clamping portion fixes the inner wall of the tire. Through the cooperative cooperation of the first clamping portion and the second clamping portion, the pressure applied by the two can be offset in the radial direction of the tire, avoiding the occurrence of the adverse situation that the tire is locally stressed unevenly and deformed due to the large thrust applied by one clamping portion alone.

[0013] When the tire is fixed, the clamping table starts to rotate relative to the operation table along the gravity direction as the axis. This automatic rotation process replaces the tedious operation of manually rotating the tire in the traditional detection mode, thereby reducing the labor intensity of the staff.

[0014] In addition, the clamping table is movably connected with the operation table through the annular member on the outer surface, so as to limit the clamping table in the gravity direction, prevent unnecessary deviation, shaking or other unstable motion state of the clamping table during rotation, and improve the stability of the clamping table during rotation.

[0015] According to another specific embodiment of the present application, each of the first clamping portions comprises:

[0016] A fixing member is protruded from the clamping table;

[0017] A first driving member is threadedly connected with the fixing member;

[0018] A first push block is connected with the first driving member at one end, and the other end of the first push block is located in the tire placing cavity, and the other end of the first push block is used for contacting the outer wall of the tire.

[0019] According to the technical scheme, before tire detection, a worker rotates the first driving member in a forward direction to move the first push block in a horizontal direction relative to the fixed member, gradually approaches the tire placed in the tire placing cavity, and stops the rotation of the first driving member until the first push block contacts the outer wall of the tire.

[0020] Similarly, when the tire detection is completed and the tire needs to be removed, the worker rotates the first driving member in a reverse direction to move the first push block in a horizontal direction relative to the fixed member, changes the first push block from contacting the outer wall of the tire to not contacting the outer wall of the tire, and gradually moves away from the tire. When the first push block moves a distance (for example, 16 cm), the tire is in a completely loosened and easy-to-operate state. In this way, the worker can easily remove the detected tire from the tire placing cavity, and then place a new tire to be detected in the tire placing cavity to start a new tire detection process.

[0021] In addition, in actual working conditions, the area of the first push block contacting the outer wall of the tire is small, for example, 8 cm 2 Therefore, the worker can observe the range of the outer wall of the tire contacting the first push block by naked eyes.

[0022] According to another specific embodiment of the utility model, the first driving member comprises:

[0023] A first handle;

[0024] A first screw rod, one end of the first screw rod is located in the clamping table and connected with the first push block, the other end of the first screw rod is located outside the clamping table and connected with the first handle, and the outer surface of the first screw rod is threadedly connected with the fixed member.

[0025] According to another specific embodiment of the utility model,

[0026] The fixed seat comprises:

[0027] A first fixed frame, the first fixed frame is a hollow structure, and is arranged in a horizontal direction and spaced from the side wall of the clamping table;

[0028] A second fixed frame, the second fixed frame is arranged in the first fixed frame, the second fixed frame is a hollow structure, and the first fixed frame and the second fixed frame define a containing cavity;

[0029] The second clamping part comprises:

[0030] A second driving member extends along the direction of gravity, one end of the second driving member is arranged in the second fixing frame, and the other end of the second driving member passes through the first fixing frame and extends out of the first fixing frame;

[0031] A transmission gear is connected with one end of the second driving member;

[0032] A plurality of driven gears are arranged in the second fixing frame at intervals along the circumference, and the plurality of driven gears are engaged with the transmission gear;

[0033] A plurality of clamping members, one end of each of the clamping members is arranged in the second fixing frame and connected with the corresponding driven gear, the other end of each of the clamping members passes through the first fixing frame and extends out of the first fixing frame, and the other end of each of the clamping members is used to contact the inner wall of the tire in the external environment; wherein,

[0034] The transmission gear can rotate in the direction of gravity as an axis to drive the plurality of driven gears to rotate in the horizontal direction as an axis, so as to drive the plurality of clamping members to move in the horizontal direction relative to the fixing seat.

[0035] According to the technical scheme, before tire detection work is performed, a worker rotates the second driving member in a forward direction, thereby driving the transmission gear to rotate in the direction of gravity as an axis in a forward direction, driving the plurality of driven gears to rotate in the horizontal direction as an axis in a forward direction, and driving the plurality of clamping members to move in the horizontal direction relative to the fixing seat, gradually approaching the tire placed in the tire placing cavity, until the clamping members contact the inner wall of the tire, and then the worker can stop rotating the second driving member in the forward direction.

[0036] Similarly, when the tire detection work is completed and the tire needs to be removed, the worker rotates the second driving member in a reverse direction, thereby driving the transmission gear to rotate in the direction of gravity as an axis in a reverse direction, driving the plurality of driven gears to rotate in the horizontal direction as an axis in a reverse direction, and driving the plurality of clamping members to move in the horizontal direction relative to the fixing seat. The plurality of clamping members are changed from contacting the inner wall of the tire to not contacting the inner wall of the tire, and gradually move away from the tire. When the plurality of clamping members move a distance (for example, 13 cm), the tire is in a completely loosened state and is convenient to operate. In this way, the worker can easily remove the detected tire from the tire placing cavity, and then place a new tire to be detected in the tire placing cavity, and start a new tire detection work process.

[0037] According to another specific embodiment of the present application, the second driving member comprises:

[0038] A second handle;

[0039] A first connecting rod extends in the direction of gravity, one end of the first connecting rod extends out of the first fixed frame and is connected with the second handle, and the other end of the first connecting rod is connected with the transmission gear to drive the transmission gear to rotate in the direction of gravity as the axial direction.

[0040] According to another specific embodiment of the present application, each of the clamping members comprises:

[0041] A second screw rod, one end of the second screw rod is located in the second fixed frame and is connected with the corresponding driven gear;

[0042] A second connecting rod, one end of the second connecting rod is located in the accommodating cavity, the other end of the second connecting rod passes through the first fixed frame and extends out of the first fixed frame, one end of the second connecting rod is threadedly connected with the second screw rod, and one end of the second connecting rod is provided with a limiting member configured to contact the inner wall of the first fixed frame;

[0043] A second push block, the second push block is located outside the first fixed frame, the second push block is connected with the other end of the second connecting rod, and the second push block is configured to contact the inner wall of the tire.

[0044] With the above technical solution, before the tire detection work is performed, the staff will move the second push block along the horizontal direction relative to the first fixed frame, and gradually approach the inner wall of the tire. When the second push block moves the maximum distance (for example, 15 cm), if there is no limiting mechanism formed by the limiting member contacting the inner wall of the first fixed frame, the end of the second connecting rod connected with the second screw rod may be separated, and the second push block may fall outside the fixed seat, so that the inner wall of the tire fails to be fixed.

[0045] In addition, in actual working conditions, the area of the second push block contacting the inner wall of the tire is small, for example, 8 cm 2 Therefore, the range of the inner wall of the tire contacting the second push block can be observed by the staff through the naked eye.

[0046] According to another specific embodiment of the present application, the transmission gear is a transmission bevel gear, and the driven gear is a driven bevel gear.

For those skilled in the art, the specific meaning of the above terms in the embodiments can be understood according to the specific circumstances.

[0083] In order to make the purpose, technical scheme and advantages of the utility model clearer, the embodiments of the utility model will be further described in detail below with reference to the drawings.

[0084] Reference Figure 1 And Figure 2 The embodiments of the present application provide a tire quality detection device, which comprises an operation table 10, a clamping table 20, a fixed seat 30, three first clamping parts 40 and second clamping parts 50.

[0085] The clamping table 20 is arranged on the operation table 10, and the clamping table 20 can rotate relative to the operation table 10 with the gravity direction G as the axial direction. The clamping table 20 comprises a ring-shaped part 21, which is arranged on the outer surface of the clamping table 20 in the circumferential direction, and the ring-shaped part 21 is movably connected with the inner wall of the operation table 10.

[0086] In the gravity direction G, the three first clamping parts 40 are protruded on the clamping table 20, and the three first clamping parts 40 are arranged at intervals in the circumferential direction, and the first clamping part 40 is used for fixing the outer wall of the tire 100 in the external environment. The second clamping part 50 is protruded on the fixed seat 30, and the second clamping part 50 is used for fixing the inner wall of the tire 100 in the external environment. In the horizontal direction, the fixed seat 30 is arranged at intervals with the first clamping part 40 to form a tire placing cavity 60.

[0087] By adopting the above technical scheme, before the tire 100 detection work is carried out, the staff first places the tire 100 to be detected in the tire placing cavity 60. At this time, the three first clamping parts 40 will fix the outer wall of the tire 100, and the second clamping part 50 will fix the inner wall of the tire 100. Through the cooperative cooperation of the first clamping part 40 and the second clamping part 50, the pressure applied by the two can be offset in the radial direction of the tire 100, avoiding the occurrence of the adverse conditions that the tire 100 is locally stressed unevenly and deformed due to the large force applied by one of the clamping parts.

[0088] When the tire 100 is fixed, the clamping table 20 starts to rotate relative to the operation table 10 with the gravity direction G as the axial direction. This automatic rotation process replaces the cumbersome operation of manually rotating the tire 100 by the staff in the traditional detection mode, thereby reducing the labor intensity of the staff.

[0089] In addition, the clamping table 20 is movably connected to the operation table 10 through the annular part 21 on the outer surface, so as to limit the clamping table 20 in the gravity direction G, prevent unnecessary deviation, shaking or other unstable motion state during rotation, and improve the stability of the clamping table 20 during rotation.

[0090] It should be noted that the number of the first clamping parts 40 is not specifically limited in the embodiments of the present application. For example, in other possible embodiments, the number of the first clamping parts 40 can be four, five, etc.

[0091] In some possible embodiments, referring to Figure 1 and Figure 2 Each first clamping part 40 includes a fixing part 41, a first driving part 42 and a first push block 43. The fixing part 41 is a cuboid, the fixing part 41 is protruded on the clamping table 20, and the first driving part 42 is threadedly connected with the fixing part 41. The first push block 43 is arc-shaped, one end of the first push block 43 is connected with the first driving part 42, and the other end of the first push block 43 is located in the tire placing cavity 60, and the other end of the first push block 43 is used to contact with the outer wall of the tire 100 outside the tire placing cavity 60.

[0092] With the above technical solution, before the tire 100 detection work is performed, the staff rotates the first driving part 42 threadedly connected with the fixing part 41 in the forward direction, so that the first push block 43 moves relative to the fixing part 41 in the horizontal direction, gradually approaches the tire 100 placed in the tire placing cavity 60, and stops rotating the first driving part 42 until the first push block 43 contacts with the outer wall of the tire 100.

[0093] Similarly, when the tire 100 detection work is completed and the detected tire 100 needs to be taken down, the staff rotates the first driving part 42 in the reverse direction, so that the first push block 43 moves relative to the fixing part 41 in the horizontal direction, the first push block 43 changes from contacting with the outer wall of the tire 100 to not contacting with the outer wall of the tire 100, and gradually moves away from the tire 100. When the first push block 43 moves a distance (for example, 16 cm), the tire 100 is in a completely loosened and easy-to-operate state. In this way, the staff can easily take the detected tire 100 from the tire placing cavity 60, and then place a new tire 100 to be detected into the tire placing cavity 60, and start a new tire 100 detection work process.

[0094] In addition, in actual working conditions, the first pushing block 43 contacts with the outer wall of the tire 100 at a small area, for example, 8 cm 2 Therefore, the range of the outer wall of the tire 100 contacting with the first pushing block 43 can be observed by the worker through naked eyes.

[0095] It should be noted that the shape of the fixing member 41 is not limited in the embodiments of the present application, for example, in other possible embodiments, the shape of the fixing member 41 can be a cylinder, a polygonal body, etc.

[0096] In some possible embodiments, referring to Figure 1 and Figure 2 , the first driving member 42 comprises a first handle 421 and a first screw rod 422, and the first handle 421 is circular. One end of the first screw rod 422 is located in the clamping table 20 and connected with the first pushing block 43, and the other end of the first screw rod 422 is located outside the clamping table 20 and connected with the first handle 421, and the outer surface of the first screw rod 422 is threadedly connected with the fixing member 41.

[0097] It should be noted that the shape of the first handle 421 is not limited in the embodiments of the present application, for example, in other possible embodiments, the shape of the first handle 421 can be a square, a triangle, etc.

[0098] In some possible embodiments, referring to Figure 1 , Figure 3 and Figure 4 , the fixed seat 30 comprises a first fixed frame 31 and a second fixed frame 32. The first fixed frame 31 is a hollow cylinder, and the first fixed frame 31 is arranged in a spaced manner with the side wall of the clamping table 20 along the horizontal direction. The second fixed frame 32 is arranged in the first fixed frame 31, and the second fixed frame 32 is a hollow cylinder, and the first fixed frame 31 and the second fixed frame 32 define a containing cavity 33.

[0099] The second clamping part 50 comprises a second driving member 51, a transmission gear 52, three driven gears 53 and three clamping members 54. The second driving member 51 extends along the gravity direction G, one end of the second driving member 51 is arranged in the second fixed frame 32, and the other end of the second driving member 51 passes through the first fixed frame 31 and extends out of the first fixed frame 31. The transmission gear 52 is connected with one end of the second driving member 51, the three driven gears 53 are arranged in the second fixed frame 32 in a spaced manner along the circumferential direction, and the three driven gears 53 are engaged with the transmission gear 52. One end of each clamping member 54 is located in the second fixed frame 32 and connected with the corresponding driven gear 53, and the other end of each clamping member 54 passes through the first fixed frame 31 and extends out of the first fixed frame 31, and the other end of each clamping member 54 is used to contact with the inner wall of the tire 100 in the outside.

[0100] The transmission gear 52 can rotate around the gravity direction G as an axis to drive the three driven gears 53 to rotate around the horizontal direction as an axis to drive the three clamping pieces 54 to move relative to the fixed base 30 along the horizontal direction.

[0101] With the above technical solution, before the tire 100 detection work is performed, the staff rotates the second driving piece 51 in the forward direction, thereby driving the transmission gear 52 to rotate in the forward direction around the gravity direction G, driving the three driven gears 53 to rotate in the forward direction around the horizontal direction as an axis, and driving the three clamping pieces 54 to move relative to the fixed base 30 along the horizontal direction, gradually approaching the tire 100 placed in the tire placing cavity 60, until the clamping pieces 54 contact the inner wall of the tire 100, and then the forward rotation of the second driving piece 51 can be stopped.

[0102] Similarly, when the tire 100 detection work is completed and the detected tire 100 needs to be removed, the staff rotates the second driving piece 51 in the reverse direction, thereby driving the transmission gear 52 to rotate in the reverse direction around the gravity direction G, driving the three driven gears 53 to rotate in the reverse direction around the horizontal direction as an axis, and driving the three clamping pieces 54 to move relative to the fixed base 30 along the horizontal direction. The three clamping pieces 54 change from contacting the inner wall of the tire 100 to not contacting the inner wall of the tire 100, and gradually move away from the tire 100. When the three clamping pieces 54 move a distance (for example, 13 cm), the tire 100 is in a completely loosened and easy-to-operate state. In this way, the staff can easily remove the detected tire 100 from the tire placing cavity 60, and then place a new tire 100 to be detected into the tire placing cavity 60, starting a new tire 100 detection work process.

[0103] It should be noted that the shape of the first fixed frame 31 is not specifically limited in the embodiments of the present application, for example, in other possible implementations, the shape of the first fixed frame 31 can be a cuboid, a triangular prism, etc. The shape of the second fixed frame 32 is not specifically limited in the embodiments of the present application, for example, in other possible implementations, the shape of the second fixed frame 32 can be a cuboid, a triangular prism, etc.

[0104] It should be noted that the number of the driven gears 53 is not specifically limited in the embodiments of the present application, for example, in other possible implementations, the number of the driven gears 53 can be four, five, etc. The number of the clamping pieces 54 is not specifically limited in the embodiments of the present application, for example, in other possible implementations, the number of the clamping pieces 54 can be four, five, etc., and the number of the clamping pieces 54 is equal to the number of the driven gears 53.

[0105] In some possible implementations, with reference to Figures 3 to 5The second driving member 51 comprises a second handle 511 and a first connecting rod 512. The second handle 511 is circular. The first connecting rod 512 is a cylinder, which extends along the gravity direction G. One end of the first connecting rod 512 extends out of the first fixed frame 31 and is connected with the second handle 511. The other end of the first connecting rod 512 is connected with the transmission gear 52 to drive the transmission gear 52 to rotate along the gravity direction G.

[0106] It should be noted that the shape of the second handle 511 is not limited in the embodiments of the present application. For example, in other possible embodiments, the shape of the second handle 511 can be square, triangular, or the like. The shape of the first connecting rod 512 is not limited in the embodiments of the present application. For example, in other possible embodiments, the shape of the first connecting rod 512 can be cuboid, triangular prism, or the like.

[0107] In some possible embodiments, referring to Figure 1 、 Figure 4 and Figure 6 each clamping member 54 comprises a second screw rod 541, a second connecting rod 542 and a second push block 543. One end of the second screw rod 541 is located in the second fixed frame 32 and is connected with the corresponding driven gear 53. The surface of the second screw rod 541 is provided with external threads 5411.

[0108] The second connecting rod 542 is a cylinder, one end of which is located in the accommodating cavity 33. One end of the second connecting rod 542 is provided with a limiting member 5421, which is circular and used to contact the inner wall of the first fixed frame 31. The inner part of one end of the second connecting rod 542 is provided with a threaded groove 5422, and the second connecting rod 542 is connected with the external threads 5411 of the second screw rod 541 through the threaded groove 5422.

[0109] The other end of the second connecting rod 542 passes through the first fixed frame 31 and extends out of the first fixed frame 31. The second push block 543 is arc-shaped, which is located outside the first fixed frame 31 and is connected with the other end of the second connecting rod 542. The second push block 543 is used to contact the inner wall of the tire 100 in the external environment.

[0110] With the above technical solutions, before the tire 100 detection work is performed, the staff will make the second push block 543 move along the horizontal direction relative to the first fixed frame 31, gradually close to the inner wall of the tire 100. When the second push block 543 moves the maximum distance (for example, 15 cm), if there is no limiting piece 5421 in contact with the inner wall of the first fixed frame 31 to form a limiting mechanism, the end of the second connecting rod 542 connected with the second screw rod 541 will be separated, and the second push block 543 will fall out of the fixed seat 30, resulting in failure of the inner wall of the tire 100.

[0111] In addition, in actual working conditions, the area of the second push block 543 in contact with the inner wall of the tire 100 is small, for example, 8 cm 2 Therefore, the range of the inner wall of the tire 100 in contact with the second push block 543 can be observed by the staff through the naked eye.

[0112] It should be noted that the shape of the second connecting rod 542 is not limited in the embodiments of the present application, for example, in other possible embodiments, the shape of the second connecting rod 542 can be a cuboid, a triangular prism, etc. The shape of the limiting piece 5421 is not limited in the embodiments of the present application, for example, in other possible embodiments, the shape of the limiting piece 5421 can be a rectangle, a triangle, etc.

[0113] In some possible embodiments, referring to Figure 4 , the transmission gear 52 is a transmission bevel gear, and the driven gear 53 is a driven bevel gear.

[0114] In some possible embodiments, referring to Figure 2 , the tire quality detection device comprises a third driving member 70, which is arranged in the operation table 10 and connected with the bottom of the clamping table 20 along the gravity direction G. The third driving member 70 is used to drive the clamping table 20 to rotate relative to the operation table 10 along the gravity direction G as the axial direction.

[0115] In some possible embodiments, referring to Figure 2 , the third driving member 70 is an electric motor.

[0116] It should be noted that the specific structure of the third driving member 70 is not limited in the embodiments of the present application, for example, in other possible embodiments, the third driving member 70 can be a pneumatic cylinder, a gear, etc.

[0117] Next, referring to Figures 1 to 4 , the working process of the tire quality detection device will be described in detail.

[0118] Before the tire 100 detection work is carried out, the staff first places the tire 100 to be detected in the tire placing cavity 60. Then the staff rotates the first handle 421 in the positive direction, so that the first screw rod 422 drives the first push block 43 to move relative to the fixed part 41 in the horizontal direction, gradually approaches the tire 100 placed in the tire placing cavity 60, until the first push block 43 contacts the outer wall of the tire 100, and the rotation of the first handle 421 can be stopped.

[0119] After the fixing of the outer wall of the tire 100 is completed, the staff rotates the second handle 511 in the positive direction, so that the first connecting rod 512 drives the transmission gear 52 to rotate in the positive direction with the gravity direction G as the axis, drives the three driven gears 53 to rotate in the horizontal direction as the axis. The positive rotation of the driven gear 53 drives the second screw rod 541 to rotate in the horizontal direction as the axis, so that the second connecting rod 542 drives the second push block 543 to move relative to the fixed base 30 in the horizontal direction, gradually approaches the tire 100 placed in the tire placing cavity 60, until the second push block 543 contacts the inner wall of the tire 100, and the rotation of the second handle 511 can be stopped. At this time, through the cooperation of the first push block 43 and the second push block 543, the fixing work of the tire 100 is realized. It should be noted that the fixing work of the outer wall and the inner wall of the tire 100 can be carried out simultaneously or separately, and the specific implementation mode is determined by the site working condition.

[0120] When the tire 100 is fixed, the third driving part 70 drives the clamping table 20 to rotate relative to the operation table 10 with the gravity direction G as the axis, so that the staff can carry out quality detection on the tire 100.

[0121] When the tire 100 detection work is completed, the staff rotates the first handle 421 in the reverse direction, so that the first screw rod 422 drives the first push block 43 to move relative to the fixed part 41 in the horizontal direction, the first push block 43 changes from contacting the outer wall of the tire 100 to not contacting the outer wall of the tire 100, and gradually moves away from the tire 100.

[0122] After the first push block 43 moves away from the tire 100, the staff rotates the second handle 511 in the reverse direction, so that the first connecting rod 512 drives the transmission gear 52 to rotate in the reverse direction with the gravity direction G as the axis, drives the three driven gears 53 to rotate in the horizontal direction as the axis. The reverse rotation of the driven gear 53 drives the second screw rod 541 to rotate in the horizontal direction as the axis, so that the second connecting rod 542 drives the second push block 543 to move relative to the fixed base 30 in the horizontal direction, the second push block 543 changes from contacting the inner wall of the tire 100 to not contacting the inner wall of the tire 100, and gradually moves away from the tire 100.

[0123] At this time, the tire 100 is in a completely loose and easy-to-operate state, and the staff can easily take the detected tire 100 out of the tire placing cavity 60, then place the next tire 100 to be detected into the tire placing cavity 60, and fix it to start a new tire 100 detection work process.
