If the specific posture changes, the directional indications will also change accordingly.

[0029] Due to reasons such as installation errors, the parallel relationship referred to in the embodiments of the present utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0030] The present utility model provides an automatic assembling device for an intelligent tire sensor and a rubber sleeve, which is applicable to the installation between a sensor 34 and a rubber sleeve 24 in a connection similar to a plunger type. In this embodiment, referring to Figure 8 as shown, the sensor 34 has a cylindrical block structure, and a corresponding cylindrical installation groove is provided on the rubber sleeve 24. The inner diameter of the installation groove is slightly smaller than the outer diameter of the sensor 34. The sensor 34 is installed into the installation groove in a squeezing form, and the fastening of the two is achieved through interference fit.

[0031] Referring to Figure 1 , the automatic assembling device includes a frame 1. Column-shaped guide rails 11 are vertically arranged on the frame 1 and are respectively located on the left and right sides. A rubber sleeve action component, a flaring component, and a sensor action component are respectively arranged on the column-shaped guide rails 11 from top to bottom.

[0032] Referring to Figure 4 and Figure 5 , the rubber sleeve action component includes a rubber sleeve positioning plate 21. The two ends of the rubber sleeve positioning plate 21 are respectively sleeved on the two column-shaped guide rails 11 and are connected to be slidable relative to the length direction of the column-shaped guide rails 11, so that the rubber sleeve positioning plate 21 can move up and down along the column-shaped guide rails 11. The bottom surface of the rubber sleeve positioning plate 21 is used to install the rubber sleeve 24. In this embodiment, the rubber sleeve 24 is arranged as a whole plate, and a plurality of rubber sleeves 24 are distributed in a multi-row array on a template 241. After the assembling operation is completed, they can be separated and removed from the template 241 one by one. A fixture 23 for clamping and fixing the template 241 is arranged on the rubber sleeve positioning plate 21. After the template 241 is installed on the rubber sleeve positioning plate 21, the installation groove of the rubber sleeve 24 is arranged downward.

[0033] One end of the fixture 23 is fixedly connected to the rubber sleeve positioning plate 21 by bolts, and the other end is located below the rubber sleeve positioning plate 21, forming a gap with a set thickness between it and the lower surface of the rubber sleeve positioning plate 21. The set thickness is slightly greater than the thickness of the template 241, and one end of the gap is open, enabling the template 241 to be inserted horizontally into the gap. After the template 241 is inserted into the gap, the fixture 23 supports the lower part of the template 241 to form a support. Multiple fixtures 23 can be provided to ensure the stability after the template 241 is installed. After the sensor 34 and the rubber sleeve 24 are installed, the entire template 241 can be withdrawn horizontally.

[0034] A first cylinder 22 is arranged above the rubber sleeve positioning plate 21. The first cylinder 22 is fixedly arranged at the top of the frame 1, and the telescopic shaft of the first cylinder 22 is connected downward to the rubber sleeve positioning plate 21 to drive the lifting action of the rubber sleeve positioning plate 21.

[0035] The sensor action assembly includes a sensor positioning plate 31. A plurality of positioning posts 33 are arranged on the sensor positioning plate 31. The positioning posts 33 are all arranged vertically. The number of the positioning posts 33 corresponds to the number of the rubber sleeves 24 on the template 241, and a plurality of positioning posts 33 are respectively located directly below a plurality of rubber sleeves 24 one by one. A slot for installing the sensor 34 is arranged at the top of the positioning post 33, and the sensors 34 corresponding to the number of the rubber sleeves 24 are respectively arranged at the tops of the positioning posts 33.

[0036] Both ends of the sensor positioning plate 31 are respectively sleeved on two cylindrical guide rails 11 and are connected to the cylindrical guide rails 11 in an axially relatively slidable manner, enabling the sensor positioning plate 31 to move up and down along the cylindrical guide rails 11.

[0037] A second cylinder 32 is arranged below the sensor positioning plate 31. The second cylinder 32 is fixedly arranged at the bottom of the frame 1, and the telescopic shaft of the second cylinder 32 is connected upward to the sensor positioning plate 31 to drive the lifting action of the sensor positioning plate 31.

[0038] Refer to Figure 6 , the flaring assembly includes a fixing plate 43. The fixing plate 43 is fixedly connected to the cylindrical guide rail 11 or the frame 1. A plurality of through holes 42 are formed in the fixing plate 43. The number of the through holes 42 is the same as the number of the positioning posts 33, and a plurality of through holes 42 are respectively located directly above a plurality of positioning posts 33 one by one for the positioning posts 33 and the sensors 34 thereon to pass through vertically.

[0039] Above the through hole 42, a guiding tube spring 4 is provided. The guiding tube spring 4 is composed of a plurality of elastic sheets 41 in a thin sheet structure. The plurality of elastic sheets 41 are arranged in an array on the outer periphery of the through hole 42 to enclose a tapered structure that converges upward from bottom to top. A through channel is vertically provided inside the guiding tube spring 4. The inner diameter of the bottom opening of the channel is larger than the diameter of the through hole 42, and the outer diameter of the top opening of the channel is smaller than the inner diameter of the mounting groove.

[0040] When the elastic sheet 41 is subjected to a force in a set direction, that is, a force applied along the radial direction of the channel, the elastic sheet 41 will undergo a bending deformation along the radial direction. Therefore, when the positioning post 33 and the sensor 34 enter from below through the through hole 42 and pass through the channel from bottom to top, the sensor 34 or the positioning post 33 will abut against the inner side wall of the elastic sheet 41 to generate a radial force, thereby causing the top of the guiding tube spring 4 to gradually expand outward in the radial direction, so that the sensor 34 and the positioning post 33 can finally completely pass through the channel.

[0041] During the installation process of the rubber sleeve 24 and the sensor 34, first, the rubber sleeve 24 is arranged on the rubber sleeve positioning plate 21, and the corresponding number of sensors 34 are arranged on the positioning post 33. The first cylinder 22 drives the rubber sleeve positioning plate 21 to move down quickly, so that the top of the guiding tube spring 4 is inserted into the mounting groove of the rubber sleeve 24, referring to Figure 2 and Figure 7 the state shown in. And the first cylinder 22 maintains a set driving force at this position to maintain the relative position of the rubber sleeve 24 and the guiding tube spring 4; at this time, the second cylinder 32 is simultaneously driven at a slow speed to drive the sensor positioning plate 31 and the positioning post 33 to move upward. Before the sensor 34 enters the through hole 42, the rubber sleeve 24 and the guiding tube spring 4 have already moved relative to each other in place. The sensor 34 passes through the through hole 42 and enters the channel. During the upward movement, it gradually pushes open the guiding tube spring 4, causing its upper end opening to expand outward and further expanding the inner diameter of the mounting groove. The positioning post 33 continues to rise to completely push the sensor 34 into the expanded mounting groove. At this time, the first cylinder 22 still maintains the set driving force to counteract the second cylinder 32, and maintains the position of the rubber sleeve 24 and the guiding tube spring 4 before ensuring that the sensor 34 can be fully pushed into the mounting groove.

[0042] In this embodiment, the driving force of the second cylinder 32 is greater than the driving force of the first cylinder 22. After the sensor 34 is pushed into the mounting groove in place, the continuous pushing of the second cylinder 32 causes the positioning post 33 to push the sensor 34 and the rubber sleeve 24 to continue to move upward, causing the guiding tube spring 4 to gradually withdraw from the mounting groove. After being completely withdrawn, the rubber sleeve 24 is no longer subjected to the expansion force, so that the inner wall of the mounting groove retracts inward and clings to the sensor 34, realizing the installation between the rubber sleeve 24 and the sensor 34, referring to Figure 3 the state shown in.

[0043] When the rubber sleeve 24 is disengaged from the guide tube spring 4, the back pressure generated between the rubber sleeve 24 and the guide tube spring 4 with respect to the second cylinder 32 disappears, resulting in an excessive instantaneous change in the driving force received by the rubber sleeve positioning plate 21. Correspondingly, the rubber sleeve positioning plate 21 will move quickly. To avoid this movement and damage to the first cylinder 22, in this embodiment, an adjustable damper 12 is further provided at the top of the frame 1. The model of the adjustable damper 12 is preferably an oil buffer AD2550 according to the propulsion force. The telescopic end of the adjustable damper 12 abuts against the rubber sleeve positioning plate 21. Therefore, when the back pressure disappears, the instantaneous excessive change in the driving force can be effectively dissipated through the adjustable damper 12, thereby ensuring a stable stroke of the rubber sleeve positioning plate 21.

[0044] Furthermore, a stroke valve 51 is provided. The stroke valve 51 can be fixedly arranged on the frame 1 or on one side of the fixing plate 43. After the rubber sleeve 24 and the sensor 34 are installed, further pushing of the second cylinder 32 will cause the sensor positioning plate 31 to contact and abut against the stroke valve 51, triggering the stroke valve 51. Then, the first cylinder 22 and the second cylinder 32 are reset, and the rubber sleeve positioning plate 21 and the sensor positioning plate 31 are reset.

[0045] In this embodiment, an air circuit control system is further provided for precise action control and propulsion force adjustment of the first cylinder 22 and the second cylinder 32. The air circuit control system further includes a filter, a two-position five-way pneumatic control valve, a stroke valve 51, and a foot valve 52. The main input air circuit is divided into three paths after passing through the filter. One path is connected to the two-position five-way pneumatic control valve, one path is connected to the stroke valve 51, and one path is connected to the foot valve 52. The other ends of the stroke valve 51 and the foot valve 52 are respectively connected to the upper port and the lower port of the two-position five-way pneumatic control valve. The right port of the two-position five-way pneumatic control valve is connected to the lower port of the first cylinder 22 and the upper port of the second cylinder 32, and the other port is connected to the upper port of the first cylinder 22 and the lower port of the second cylinder 32. Throttle valves are respectively added to the above four air paths to adjust the size of the air.

[0046] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
