[0035] To facilitate the description of the advantages of the vehicle positioning device in the embodiments of this application, at the beginning of the detailed description of the technical solutions in the embodiments of this application, an overview of the relevant content of the prior art is first given:

[0036] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a vehicle positioning device in the prior art. Figure 1 In , when the blocking mechanism 90 stops the vehicle 70, the vehicle 70 will rebound, resulting in inaccurate induction of the sensor 100; at the same time, due to the high-frequency collision between the vehicle 70 and the blocking mechanism 90, the sensor 100 is prone to looseness, resulting in inaccurate induction or even being damaged by the collision of the sensor 100; in addition, the lifting mechanism lifts the vehicle 70 to the working position, and there is a gap between the vehicle 70 and the positioning cover plate at the working position and they cannot be in full contact, resulting in inaccurate positioning of the small components in the vehicle 70 and unable to complete high-quality assembly operations.

[0037] In view of the deficiencies of the prior art, the vehicle positioning device of the present application is provided with a buffer assembly to absorb the kinetic energy of the vehicle and stop the vehicle, which is beneficial to solving the problem of vehicle rebound. At the same time, a telescopic mechanism is provided to indirectly transmit the position information of the vehicle, and a position sensor with a fixed direction different from the movement direction of the vehicle is provided to sense the position information of the positioning member from the side, which is beneficial to solving the problems of easy loosening and inaccurate sensing of the position sensor.

[0038] The following introduces the technical solutions in the embodiments of the present application with reference to the accompanying drawings.

[0039] Please refer to Figures 2 to 4 , in the embodiment of the present application, the vehicle positioning device includes a streamline fixed platform 10, and also includes a blocking base 20, a position sensor 30, a telescopic mechanism 40 and a buffer assembly 50. The position sensor 30 is electrically connected to the streamline controller; the blocking base 20 is fixedly arranged on the streamline fixed platform 10, and a sensor fixing hole 21 is arranged on the blocking base 20. The position sensor 30 matches the sensor fixing hole 21, and the axial direction of the sensor fixing hole 21 is different from the movement direction of the streamline 60; the telescopic mechanism 40 is slidably connected to the blocking base 20, and the sliding direction of the telescopic mechanism 40 is the same as the movement direction of the streamline 60; one end of the telescopic mechanism 40 is provided with a vehicle abutting end 41, and the end of the telescopic mechanism 40 away from the vehicle abutting end 41 is provided with a positioning member 42. During the sliding process of the telescopic mechanism 40, the positioning member 42 enters or exits the position sensing area of the position sensor 30; the buffer assembly 50 is fixedly arranged on the blocking base 20, and one end of the buffer assembly 50 facing the vehicle 70 is provided with a vehicle buffer end 51, and the compression direction of the vehicle buffer end 51 is the same as the movement direction of the streamline 60.

[0040] In the embodiment of the present application, the position sensor 30 is fixedly connected to the blocking base 20 through the sensor fixing hole 21. Specifically, the position sensor 30 and the blocking base 20 can be fixedly connected by fasteners, and the fixed connection methods can include but are not limited to screwing or clamping, etc.

[0041] In one embodiment, the sensor fixing hole 21 is provided with internal threads, the outer periphery of the position sensor 30 is provided with external threads, the internal threads of the sensor fixing hole 21 and the external threads of the position sensor 30 are screwed and fixed. At the same time, first nuts are locked on both sides of the position sensor 30 relative to the sensor fixing hole 21, so as to further fix the position sensor 30.

[0042] In the embodiment of the present application, the axial direction of the sensor fixing hole 21 is different from the movement direction of the vehicle 70. The position sensor 30 is used to sense the position information of the positioning member 42 from the side and transmit the position information of the positioning member 42 to the streamline controller. Since the vehicle 70 impacts the vehicle buffer end 51 frequently, it is extremely easy to cause the position sensor 30 to loosen. Thus, it is beneficial to solve the problems of easy loosening and inaccurate sensing of the position sensor 30.

[0043] In the embodiment of the present application, a sliding through hole 24 is provided on the blocking base 20. The sliding through hole 24 is matched with the telescopic mechanism 40, and the telescopic mechanism 40 is slidably connected to the blocking base 20 through the sliding through hole 24.

[0044] Furthermore, the sliding direction of the telescopic mechanism 40 is consistent with the moving direction of the vehicle 70, and the telescopic mechanism 40 is used to transmit the position information of the vehicle 70 to the position sensor 30.

[0045] Specifically, both ends of the telescopic mechanism 40 along the moving direction of the vehicle 70 protrude from the blocking base 20. A vehicle abutting end 41 is provided at one end of the telescopic mechanism 40 close to the vehicle 70, and a positioning member 42 is provided at one end of the telescopic mechanism 40 close to the position sensor 30.

[0046] In one embodiment, the positioning member 42 is an L-shaped iron positioning member, which can enter or leave the position sensing area of the position sensor 30.

[0047] In another embodiment, the positioning member 42 is an aluminum positioning member, which can enter or leave the position sensing area of the position sensor 30.

[0048] In another embodiment, the positioning member 42 is a plastic positioning member, which can enter or leave the position sensing area of the position sensor 30.

[0049] In the embodiment of the present application, a buffer assembly positioning hole 23 is provided on the blocking base 20. The buffer assembly positioning hole 23 is matched with the buffer assembly 50, and the buffer assembly 50 is fixedly connected to the blocking base 20 through the buffer assembly positioning hole 23. Specifically, the buffer assembly 50 and the blocking base 20 can be fixedly connected by fasteners, and the fixed connection methods can include but are not limited to screwing or clamping.

[0050] In one embodiment, the buffer assembly positioning hole 23 is provided with internal threads, the outer periphery of the buffer assembly 50 is provided with external threads, and the internal threads of the buffer assembly positioning hole 23 are screwed with the external threads of the buffer assembly 50 for fixation. At the same time, second nuts are locked on both sides of the buffer assembly 50 relative to the buffer assembly positioning hole 23, so as to further fix the buffer assembly 50.

[0051] In the embodiment of the present application, the compression direction of the vehicle buffer end 51 is consistent with the moving direction of the vehicle 70, and the vehicle buffer end 51 is used to abut against the vehicle 70. The vehicle 70 abuts against and compresses the buffer assembly 50, so that the buffer assembly 50 absorbs the kinetic energy of the vehicle 70 to smoothly stop the vehicle 70, which is beneficial to solving the problem of the vehicle 70 rebounding.

[0052] In one embodiment, the telescopic mechanism 40 is disposed at the central position of the blocking base 20. The vehicle positioning device includes two buffer components 50. Correspondingly, two buffer component positioning holes 23 are provided on the blocking base 20. Specifically, the buffer components 50 are symmetrically disposed on both sides of the telescopic mechanism 40.

[0053] Preferably, the buffer component 50 includes a hydraulic buffer.

[0054] In one embodiment, the weight of the vehicle 70 is 5 KG, and the maximum speed of the vehicle 70 is 700 mm / s. Thus, the maximum kinetic energy of the vehicle 70 can be calculated as 1.23 N·M. Correspondingly, two hydraulic buffers with a maximum energy absorption of 2 N·M can be selected.

[0055] In the embodiment of the present application, when there is a gap between the vehicle 70 and the vehicle abutting end 41, the positioning member 42 is away from the position sensing area of the position sensor 30; when the vehicle 70 is smoothly blocked by the buffer component 50, the positioning member 42 enters the position sensing area of the position sensor 30.

[0056] Specifically, the position sensor 30 may include, but is not limited to, a proximity switch.

[0057] Specifically, the streamline 60 includes a conveyor belt 61. The vehicle 70 is carried above the conveyor belt 61. The conveyor belt 61 moves under the drive of the streamline drive mechanism. The vehicle 70 moves synchronously with the conveyor belt 61. When the vehicle 70 moves to the lower area of the target working position, the vehicle 70 abuts against and compresses the vehicle buffer end 51. The buffer component 50 absorbs the kinetic energy of the vehicle 70 and smoothly blocks the vehicle 70; meanwhile, the vehicle 70 abuts against and pushes the vehicle abutting end 41. Thus, the telescopic mechanism 40 drives the positioning member 42 to slide along the sliding through hole 24, and the positioning member 42 enters the position sensing area of the position sensor 30; at this time, the position sensor 30 senses the position information of the positioning member 42 and sends the position information of the positioning member 42 to the streamline controller. This position information indicates that the vehicle 70 has been smoothly blocked at the target position.

[0058] In the embodiment of the present application, the vehicle positioning device is provided with the buffer component 50 to absorb the kinetic energy of the vehicle 70 to smoothly block the vehicle 70, which is beneficial to solving the problem of vehicle 70 rebound; at the same time, the telescopic mechanism 40 is provided to indirectly transmit the position information of the vehicle 70, and the position sensor 30 with a fixed direction different from the movement direction of the vehicle 70 senses the position information of the positioning member 42 from the side, which is beneficial to solving the problems of easy loosening and inaccurate sensing of the position sensor 30.

[0059] In the embodiment of the present application, please refer to Figure 5 and Figure 6, the vehicle positioning device further includes a jacking mechanism 80, and the jacking mechanism 80 is electrically connected to the streamline controller; the jacking mechanism 80 includes a fixedly connected jacking transmission assembly 81 and a jacking plate 82. The jacking transmission assembly 81 is fixedly connected to the streamline fixed platform 10. On the side of the jacking plate 82 facing the vehicle 70, there is a jacking plate positioning portion 821, and the jacking plate positioning portion 821 is in clearance fit with the first vehicle positioning portion on the vehicle 70.

[0060] In the embodiment of the present application, the jacking plate 82 is used to position and carry the vehicle 70.

[0061] In one embodiment, the jacking plate positioning portion 821 protrudes from the jacking plate 82. Correspondingly, the first vehicle positioning portion includes a vehicle positioning hole, and the vehicle positioning hole is in clearance fit with the jacking plate positioning portion 821. In this way, the vehicle 70 is positioned to the jacking plate 82.

[0062] In another embodiment, the jacking plate positioning portion 821 includes a jacking plate positioning hole. Correspondingly, the first vehicle positioning portion protrudes downward on the side of the vehicle 70 close to the jacking plate 82, and the jacking plate positioning hole is in clearance fit with the first vehicle positioning portion. In this way, the vehicle 70 is positioned to the jacking plate 82.

[0063] In one embodiment, there are 2 jacking plate positioning portions 821 provided on the jacking plate 82. Preferably, the jacking plate positioning portions 821 are arranged along the diagonal of the jacking plate 82.

[0064] In one embodiment, there are 4 jacking plate positioning portions 821 provided on the jacking plate 82. Preferably, the jacking plate positioning portions 821 are arranged at the four corners of the jacking plate 82.

[0065] In the embodiment of the present application, after receiving the position information of the positioning member 42 transmitted by the position sensor 30, the streamline controller controls the jacking transmission assembly 81 to perform a jacking movement. At the same time, the jacking plate 82 carries the vehicle 70 and moves towards the target working position, so that the vehicle 70 moves to the target working position.

[0066] In one embodiment, there is a positioning cover plate 120 provided at the target working position. There is a cover plate fixing position on the positioning cover plate 120. A second vehicle positioning portion is provided on the side of the vehicle 70 close to the positioning cover plate 120. The cover plate fixing position is in clearance fit with the second vehicle positioning portion. In this way, the fine positioning of the vehicle 70 is realized, which is convenient for high-quality assembly operations.

[0067] In the embodiment of the present application, an elastic support member 822 protrudes from the side of the jacking plate 82 facing the vehicle 70.

[0068] In the embodiment of the present application, please refer to Figure 7, the elastic support member 822 is used to support the carrier 70. When the carrier 70 is lifted to contact the positioning cover plate 120, the elastic support member 822 can be partially compressed so that the carrier 70 and the positioning cover plate 120 are in full contact. In this way, the problem of poor contact between the carrier 70 and the positioning cover plate 120 caused by the poor flatness of the lifting plate 82, the carrier 70, and the positioning cover plate 120 can be solved, thereby improving the positioning accuracy of the carrier 70.

[0069] In one embodiment, eight elastic support members 822 are provided on the plate surface of the lifting plate 82, and the elastic support members 822 are cylindrical support members. Specifically, the protruding height of the elastic support member 822 can be 0.5 mm, and the hardness of the elastic support member 822 can be A80.

[0070] In another embodiment, four elastic support members 822 are provided on the plate surface of the lifting plate 82, and the elastic support members 822 are rectangular parallelepiped support members. Specifically, the protruding height of the elastic support member 822 can be 0.5 mm, and the hardness of the elastic support member 822 can be A80.

[0071] Specifically, the elastic support member 822 can include, but is not limited to, a polyurethane flexible boss.

[0072] In the embodiment of the present application, please refer to Figure 7 , a receiving groove 823 is provided on the side of the lifting plate 82 facing the carrier 70.

[0073] In the embodiment of the present application, the carrier 70 is used to carry micro-components, and the micro-components include, but are not limited to, small components on a mobile phone. The receiving groove 823 can receive the micro-components that accidentally fall from the carrier 70 onto the lifting plate 82, and can also receive other foreign objects that fall onto the lifting plate 82. In this way, the influence of the micro-components and other foreign objects that accidentally fall from the carrier 70 onto the lifting plate 82 on the positioning accuracy of the carrier 70 can be avoided to the greatest extent.

[0074] Specifically, the receiving groove 823 is a special-shaped receiving groove.

[0075] Preferably, a guiding inclined surface is provided on the plate surface of the lifting plate 82 around the receiving groove 823. In this way, it is convenient for the micro-components and other foreign objects that accidentally fall from the carrier 70 onto the lifting plate 82 to slide along the guiding inclined angle into the receiving groove 823.

[0076] In the embodiment of the present application, the telescopic mechanism 40 includes a telescopic rod 43. The telescopic rod 43 is slidably connected to the blocking base 20, and the carrier abutting end 41 is provided on the telescopic rod 43.

[0077] In the embodiment of the present application, the telescopic rod 43 is slidably connected to the blocking base 20 through a sliding through hole 24, and the sliding direction of the telescopic rod 43 is the same as the moving direction of the carrier 70.

[0078] Furthermore, both ends of the telescopic rod 43 protruding along the moving direction of the vehicle 70 are disposed on the blocking base 20. One end of the telescopic rod 43 is provided with a vehicle abutting end 41, and the other end of the telescopic rod 43 is fixedly connected to the positioning member 42. Specifically, the positioning member 42 and the telescopic rod 43 can be fixedly connected by fasteners, and the fixed connection method can include but is not limited to screwing or clamping, etc.

[0079] In one embodiment, a positioning flat is provided at the end of the telescopic rod 43 away from the vehicle 70, and a flat hole is provided on the positioning member 42. The positioning flat and the flat hole are matched. At the same time, a setscrew 130 is provided to fix the positioning member 42, so as to realize the positioning and fixing of the positioning member 42.

[0080] In the embodiment of the present application, a strengthening structure 411 is provided on the vehicle abutting end 41.

[0081] Specifically, the strengthening structure 411 can be made of wear-resistant and impact-resistant materials, so as to extend the service life of the telescopic rod 43 and improve the accuracy of the position sensor 30 sensing.

[0082] In the embodiment of the present application, either the blocking base 20 or the telescopic rod 43 is provided with a limiting groove, and the other is provided with a limiting sliding part that cooperates with the limiting groove, and the limiting sliding part moves relative to the limiting groove.

[0083] In the embodiment of the present application, the limiting groove and the limiting sliding part cooperate to limit the extreme movement position of the telescopic rod 43 and limit the rotation of the telescopic rod 43. Specifically, the dimension of the limiting groove along the moving direction of the vehicle 70 is adapted to the compression amount of the vehicle 70 on the telescopic rod 43.

[0084] It should be noted that during the sliding process of the telescopic rod 43 in the sliding through hole 24, due to the cooperation and constraint of the limiting groove and the limiting sliding part, the telescopic rod 43 can only perform corresponding translational motion. During this period, there is no relative rotation between the telescopic rod 43 and the blocking base 20.

[0085] In one embodiment, a limiting groove 431 is provided on the telescopic rod 43, and a limiting sliding part 22 that matches the limiting groove 431 is provided on the blocking base 20. The limiting groove 431 and the limiting sliding part 22 can perform relative sliding. Specifically, the limiting sliding part 22 is a first pin shaft fixedly connected to the blocking base 20.

[0086] In another embodiment, a limiting sliding part is provided on the telescopic rod 43, and a limiting groove that matches the limiting sliding part is provided on the blocking base 20. The limiting groove and the limiting sliding part can perform relative sliding. Specifically, the limiting sliding part is a second pin shaft fixedly connected to the telescopic rod 43.

[0087] In the embodiment of the present application, the telescopic mechanism 40 further includes an elastic member 44, and the elastic member 44 is disposed between the telescopic rod 43 and the blocking base 20; the elastic member 44 is sleeved on the telescopic rod 43, and the elastic force direction of the elastic member 44 is coaxial with the sliding direction of the telescopic rod 43.

[0088] In the embodiment of the present application, the elastic member 44 is used for the reset of the telescopic rod 43. While the carrier 70 pushes the telescopic rod 43 to move, the elastic member 44 is compressed. When the carrier 70 is lifted by the lifting mechanism 80 and moves away from the telescopic rod 43, the telescopic rod 43 returns to the initial position under the action of the resilience of the elastic member 44.

[0089] Specifically, the elastic member 44 may include, but is not limited to, a compression spring.

[0090] In the embodiment of the present application, when a limiting groove 431 is provided on the telescopic rod 43 and a limiting sliding portion 22 is provided on the blocking base 20, the limiting sliding portion 22 protrudes from the limiting groove 431. One end of the elastic member 44 abuts against the telescopic rod 43, and the other end of the elastic member 44 abuts against the limiting sliding portion 22.

[0091] In one embodiment, the limiting sliding portion 22 is a first pin shaft, and the first pin shaft protrudes from the limiting groove 431. The end of the elastic member 44 away from the carrier 70 abuts against the first pin shaft. In this way, the structural complexity of the carrier positioning device can be reduced.

[0092] In the embodiment of the present application, the axial direction of the inductor fixing hole 21 is perpendicular to the movement direction of the streamline 60. There is a high-frequency impact between the carrier 70 and the carrier buffer end 51. In this way, the phenomenon that the position inductor 30 becomes loose due to the high-frequency impact can be minimized, thereby preventing the position inductor 30 from being damaged and improving the sensing accuracy of the position inductor 30.

[0093] In the embodiment of the present application, in the movement direction of the carrier 70, there is a first gap between the end of the position inductor 30 protruding from the blocking base 20 and the blocking base 20. Preferably, the first gap can be 7.5 mm.

[0094] In the embodiment of the present application, when the positioning member 42 enters the position sensing area of the position inductor 30, there is a gap between the positioning member 42 and the position inductor 30. In this way, the position inductor 30 can be prevented from being damaged by collision.

[0095] Further, after the positioning member 42 enters the position sensing area of the position inductor 30 and reaches the movement limit position of the positioning member 42, there is a gap between the positioning member 42 and the position inductor 30.

[0096] Specifically, in the direction perpendicular to the movement direction of the carrier 70, there is a second gap between the positioning member 42 and the position inductor 30. Preferably, the second gap can be 1 mm.

[0097] In the implementation of this application, please refer to Figure 5 , the streamline drive mechanism drives the conveyor belt 61 to move. The carrier 70 is carried on the conveyor belt 61 and moves synchronously with the conveyor belt 61. When the carrier 70 moves to the lower area of the target working position, the carrier 70 abuts against and compresses the carrier buffer end 51, and the buffer assembly 50 absorbs the kinetic energy of the carrier 70, so that the carrier 70 is smoothly blocked; at the same time, the carrier 70 abuts against and pushes the carrier abutting end 41. Thus, the telescopic rod 43 drives the positioning member 42 to perform translational motion along the sliding through hole 24, and the positioning member 42 enters the position sensing area of the position sensor 30; at this time, the position sensor 30 senses the position information of the positioning member 42 and sends the position information of the positioning member 42 to the streamline controller. This position information indicates that the carrier 70 has been smoothly blocked at the target position; furthermore, the streamline controller controls the lifting transmission assembly 81 to perform a lifting motion. At the same time, the lifting plate 82 carries the carrier 70 towards the target working position, so that the carrier 70 moves to the target working position. Please refer to Figure 5 ; at this time, since the carrier 70 is away from the carrier abutting end 41, the telescopic rod 43 returns to the initial position under the action of the resilience of the elastic member 44. Please refer to Figure 6 .

[0098] In the embodiment of this application, the carrier positioning device is provided with a buffer assembly 50 to absorb the kinetic energy of the carrier 70 to smoothly block the carrier 70, which is beneficial to solving the problem of the carrier 70 rebounding; at the same time, a telescopic mechanism 40 is provided to indirectly transmit the position information of the carrier 70, and a position sensor 30 with a fixed direction perpendicular to the movement direction of the carrier 70 is provided to sense the position information of the positioning member 42 from the front side, which is beneficial to solving the problems that the position sensor 30 is easy to loosen and the sensing is inaccurate.

[0099] In addition, an elastic support member 822 is protrudingly provided on the lifting plate 82, which is beneficial to solving the problem of inaccurate positioning of the carrier 70 caused by incomplete contact between the carrier 70 and the positioning cover plate 120; a receiving groove 823 is provided on the lifting plate 82, which can maximize the avoidance of the influence of small parts and other foreign objects accidentally falling from the carrier 70 onto the lifting plate 82 on the positioning accuracy of the carrier 70, thereby improving the positioning accuracy of the carrier 70.

[0100] The following introduces the specific embodiments of this application based on the above technical solutions.

[0101] Embodiment 1

[0102] Please refer to Figures 2 to 7, Embodiment 1 provides a vehicle positioning device, including a streamlined fixed platform 10, and further including a blocking base 20, a position sensor 30, a telescopic mechanism 40 and a buffer assembly 50. The position sensor 30 is electrically connected to a streamline controller; the blocking base 20 is fixedly arranged on the streamlined fixed platform 10. An inductor fixing hole 21 is arranged on the blocking base 20, and the position sensor 30 matches the inductor fixing hole 21. The axial direction of the inductor fixing hole 21 is not in the same direction as the movement direction of the streamline 60; the telescopic mechanism 40 is slidably connected to the blocking base 20, and the sliding direction of the telescopic mechanism 40 is the same as the movement direction of the streamline 60; one end of the telescopic mechanism 40 is provided with a vehicle abutting end 41, and the end of the telescopic mechanism 40 away from the vehicle abutting end 41 is provided with a positioning member 42. During the sliding process of the telescopic mechanism 40, the positioning member 42 enters or exits the position sensing area of the position sensor 30; the buffer assembly 50 is fixedly arranged on the blocking base 20, and one end of the buffer assembly 50 facing the vehicle 70 is provided with a vehicle buffer end 51. The compression direction of the vehicle buffer end 51 is the same as the movement direction of the streamline 60.

[0103] Furthermore, the vehicle positioning device includes 2 buffer assemblies 50. The buffer assemblies 50 are symmetrically arranged on both sides of the telescopic mechanism 40. Correspondingly, 2 buffer assembly positioning holes 23 are arranged on the blocking base 20.

[0104] Specifically, the weight of the vehicle 70 is 5KG, and the maximum speed of the vehicle 70 is 700mm / s. Correspondingly, the buffer assembly 50 selects an oil buffer with the model SAC-0806-C.

[0105] Furthermore, the compression direction of the vehicle buffer end 51 is the same as the movement direction of the vehicle 70. The vehicle buffer end 51 is used to abut against the vehicle 70. The vehicle 70 abuts against and compresses the buffer assembly 50, so that the buffer assembly 50 absorbs the kinetic energy of the vehicle 70 to smoothly stop the vehicle 70, which is beneficial to solving the problem of the vehicle 70 rebounding.

[0106] The buffer assembly positioning hole 23 is provided with internal threads, and the outer periphery of the buffer assembly 50 is provided with external threads. The internal threads of the buffer assembly positioning hole 23 are screwed and fixed with the external threads of the buffer assembly 50. At the same time, second nuts are locked on both sides of the buffer assembly 50 relative to the buffer assembly positioning hole 23, so as to further fix the buffer assembly 50.

[0107] Furthermore, a sliding through hole 24 is arranged on the blocking base 20. The sliding through hole 24 matches the telescopic rod 43. The telescopic rod 43 is slidably connected to the blocking base 20 through the sliding through hole 24, and the sliding direction of the telescopic rod 43 is the same as the movement direction of the vehicle 70.

[0108] Further, both ends of the telescopic rod 43 in the moving direction of the vehicle 70 protrude from the blocking base 20. One end of the telescopic rod 43 is provided with a vehicle abutting end 41, and the other end of the telescopic rod 43 is fixedly connected to the positioning member 42.

[0109] Further, a strengthening structure 411 is provided on the vehicle abutting end 41. The strengthening structure 411 is wear-resistant and impact-resistant. In this way, the service life of the telescopic rod 43 can be extended and the accuracy of the position sensor 30 can be improved.

[0110] Further, a positioning flat is provided at one end of the telescopic rod 43 away from the vehicle 70, and a flat hole is provided on the positioning member 42. The positioning flat and the flat hole are matched. At the same time, a set screw 130 is provided to fix the positioning member 42. In this way, the positioning and fixing of the positioning member 42 are realized.

[0111] Specifically, the positioning member 42 is an L-shaped iron positioning member and can enter or leave the position sensing area of the position sensor 30.

[0112] Further, a limiting groove 431 is provided on the telescopic rod 43, and a limiting sliding part 22 matching the limiting groove 431 is provided on the blocking base 20. The limiting groove 431 and the limiting sliding part 22 can slide relatively.

[0113] Specifically, the limiting groove 431 and the limiting sliding part 22 cooperate to limit the extreme movement position of the telescopic rod 43 and limit the rotation of the telescopic rod 43. Specifically, the dimension of the limiting groove 431 in the moving direction of the vehicle 70 is adapted to the compression amount of the vehicle 70 on the telescopic rod 43.

[0114] It should be noted that during the sliding process of the telescopic rod 43 in the sliding through hole 24, due to the cooperation and constraint of the limiting groove 431 and the limiting sliding part 22, the telescopic rod 43 can only perform corresponding translational motion. During this period, there is no relative rotation between the telescopic rod 43 and the blocking base 20.

[0115] Further, the limiting sliding part 22 protrudes from the limiting groove 431.

[0116] Further, the telescopic mechanism 40 further includes an elastic member 44. The elastic member 44 is sleeved on the telescopic rod 43. One end of the elastic member 44 abuts against the telescopic rod 43, and the other end of the elastic member 44 abuts against the limiting sliding part 22. In this way, the structural complexity of the vehicle positioning device can be reduced.

[0117] Specifically, the limiting sliding part 22 is a first pin shaft, and the elastic member 44 is a compression spring.

[0118] Specifically, the compression spring is used for the reset of the telescopic rod 43. When the vehicle 70 pushes the telescopic rod 43 to move, the compression spring is compressed. When the vehicle 70 is lifted by the lifting mechanism 80 and moves away from the telescopic rod 43, the telescopic rod 43 returns to its initial position under the action of the resilience of the compression spring.

[0119] Furthermore, the axial direction of the sensor fixing hole 21 is perpendicular to the movement direction of the streamline 60. There is a high-frequency impact between the vehicle 70 and the vehicle buffer end 51. In this way, the phenomenon of loosening of the position sensor 30 caused by the high-frequency impact can be minimized, thereby preventing the position sensor 30 from being damaged and improving the accuracy of the position sensor 30 sensing.

[0120] Furthermore, in the movement direction of the vehicle 70, the first gap between the end of the position sensor 30 extending out of the blocking base 20 and the blocking base 20 is 7.5 mm.

[0121] Furthermore, in the direction perpendicular to the movement direction of the vehicle 70, the second gap between the positioning member 42 and the position sensor 30 is 1 mm. In this way, the position sensor 30 can be prevented from being damaged by collision.

[0122] Furthermore, the sensor fixing hole 21 is provided with internal threads, the outer periphery of the position sensor 30 is provided with external threads, and the internal threads of the sensor fixing hole 21 and the external threads of the position sensor 30 are screwed and fixed. At the same time, first nuts are locked on both sides of the position sensor 30 relative to the sensor fixing hole 21, so as to further fix the position sensor 30.

[0123] Furthermore, when there is a gap between the vehicle 70 and the vehicle abutting end 41, the positioning member 42 is away from the position sensing area of the position sensor 30; when the vehicle 70 is smoothly blocked and stopped by the buffer assembly 50, the positioning member 42 enters the position sensing area of the position sensor 30.

[0124] Specifically, the position sensor 30 is a proximity switch.

[0125] Furthermore, the vehicle positioning device further includes a lifting mechanism 80, and the lifting mechanism 80 is electrically connected to the streamline controller; the lifting mechanism 80 includes a lifting transmission component 81 and a lifting plate 82 fixedly connected. The lifting transmission component 81 is fixedly connected to the streamline fixing table 10. A lifting plate positioning portion 821 protrudes from the side of the lifting plate 82 facing the vehicle 70. Correspondingly, the first vehicle positioning portion includes a vehicle positioning hole, and the vehicle positioning hole is in clearance fit with the lifting plate positioning portion 821, so as to position the vehicle 70 to the lifting plate 82.

[0126] Furthermore, the lifting plate 82 is used to position and carry the vehicle 70.

[0127] Further, two jacking plate positioning portions 821 are provided on the jacking plate 82, and the jacking plate positioning portions 821 are arranged along the diagonal of the jacking plate 82.

[0128] Further, eight elastic support members 822 protrude from one side plate surface of the jacking plate 82 facing the carrier 70. The elastic support members 822 are used to support the carrier 70. When the carrier 70 is jacked up and contacts the positioning cover plate 120, the elastic support members 822 can be partially compressed so that the carrier 70 and the positioning cover plate 120 are in full contact. In this way, the problem of poor contact between the carrier 70 and the positioning cover plate 120 caused by the poor flatness of the jacking plate 82, the carrier 70, and the positioning cover plate 120 can be solved, thereby improving the positioning accuracy of the carrier 70.

[0129] Specifically, the elastic support member 822 is a cylindrical support member. The protruding height of the elastic support member 822 can be 0.5 mm, and the hardness of the elastic support member 822 can be A80.

[0130] Further, a special-shaped storage groove 823 is provided on one side of the jacking plate 82 facing the carrier 70. The storage groove 823 can store the tiny parts that accidentally fall from the carrier 70 onto the jacking plate 82, and can also store other foreign objects that fall onto the jacking plate 82. In this way, the influence of the tiny parts and other foreign objects that accidentally fall from the carrier 70 onto the jacking plate 82 on the positioning accuracy of the carrier 70 can be avoided to the greatest extent.

[0131] Specifically, a guiding chamfer is provided on the storage groove 823, so that it is convenient for the tiny parts and other foreign objects that accidentally fall from the carrier 70 onto the jacking plate 82 to slide into the storage groove 823 along the guiding chamfer.

[0132] In Embodiment 1, the streamline driving mechanism drives the conveyor belt 61 to move. The carrier 70 is carried on the conveyor belt 61 and moves synchronously with the conveyor belt 61. When the carrier 70 moves to the lower area of the target working position, the carrier 70 abuts against and compresses the carrier buffer end 51, and the buffer assembly 50 absorbs the kinetic energy of the carrier 70, so that the carrier 70 is smoothly blocked; at the same time, the carrier 70 abuts against and pushes the carrier abutting end 41. Thus, the telescopic rod 43 drives the positioning member 42 to perform a translational motion along the sliding through hole 24, and the positioning member 42 enters the position sensing area of the position sensor 30; at this time, the position sensor 30 senses the position information of the positioning member 42 and sends the position information of the positioning member 42 to the streamline controller. This position information indicates that the carrier 70 has been smoothly blocked at the target position; furthermore, the streamline controller controls the jacking transmission assembly 81 to perform a jacking motion. At the same time, the jacking plate 82 carries the carrier 70 and moves towards the target working position, so that the carrier 70 moves to the target working position; at this time, since the carrier 70 is far from the carrier abutting end 41, the telescopic rod 43 returns to the initial position under the action of the resilience of the elastic member 44.

[0133] The vehicle positioning device in Embodiment 1 is provided with a buffer assembly 50 to absorb the kinetic energy of the vehicle 70 and smoothly stop the vehicle 70, which is beneficial to solving the problem of vehicle 70 rebounding. At the same time, a telescopic mechanism 40 is provided to indirectly transmit the position information of the vehicle 70, and a position sensor 30 with a fixed direction perpendicular to the moving direction of the vehicle 70 is provided to sense the position information of the positioning member 42 from the front side, which is beneficial to solving the problems of easy loosening and inaccurate sensing of the position sensor 30.

[0134] In addition, an elastic support member 822 is protrudingly provided on the lifting plate 82, which is beneficial to solving the problem of inaccurate positioning of the vehicle 70 caused by incomplete contact between the vehicle 70 and the positioning cover plate 120. A receiving groove 823 is provided on the lifting plate 82, which can maximize the avoidance of the influence of small parts and other foreign objects accidentally falling from the vehicle 70 onto the lifting plate 82 on the positioning accuracy of the vehicle 70, thereby improving the positioning accuracy of the vehicle 70.

[0135] Embodiment 2

[0136] Please refer to Figures 2 to 7 , Embodiment 2 provides a vehicle positioning device, including a streamline fixed platform 10, and further including a blocking base 20, a position sensor 30, a telescopic mechanism 40 and a buffer assembly 50. The position sensor 30 is electrically connected to a streamline controller; the blocking base 20 is fixedly arranged on the streamline fixed platform 10, and a sensor fixing hole 21 is provided on the blocking base 20. The position sensor 30 matches the sensor fixing hole 21, and the axial direction of the sensor fixing hole 21 is not in the same direction as the moving direction of the streamline 60; the telescopic mechanism 40 is slidably connected to the blocking base 20, and the sliding direction of the telescopic mechanism 40 is the same as the moving direction of the streamline 60; one end of the telescopic mechanism 40 is provided with a vehicle abutting end 41, and the end of the telescopic mechanism 40 away from the vehicle abutting end 41 is provided with a positioning member 42. During the sliding process of the telescopic mechanism 40, the positioning member 42 enters or exits the position sensing area of the position sensor 30; the buffer assembly 50 is fixedly arranged on the blocking base 20, and one end of the buffer assembly 50 facing the vehicle 70 is provided with a vehicle buffer end 51, and the compression direction of the vehicle buffer end 51 is the same as the moving direction of the streamline 60.

[0137] Further, the vehicle positioning device includes 2 buffer assemblies 50, and the buffer assemblies 50 are symmetrically arranged on both sides of the telescopic mechanism 40. Correspondingly, 2 buffer assembly positioning holes 23 are provided on the blocking base 20.

[0138] Specifically, the weight of the vehicle 70 is 5KG, and the maximum speed of the vehicle 70 is 700mm / s. Correspondingly, the buffer assembly 50 selects an oil buffer with the model SAC-0806-C.

[0139] Further, the compression direction of the vehicle buffer end 51 is consistent with the moving direction of the vehicle 70, and the vehicle buffer end 51 is used to abut against the vehicle 70. The vehicle 70 abuts against and compresses the buffer assembly 50, enabling the buffer assembly 50 to absorb the kinetic energy of the vehicle 70, so as to stably stop the vehicle 70, which is beneficial to solving the problem of the vehicle 70 rebounding.

[0140] The buffer assembly positioning hole 23 is provided with internal threads, and the outer periphery of the buffer assembly 50 is provided with external threads. The internal threads of the buffer assembly positioning hole 23 are screwed and fixed with the external threads of the buffer assembly 50. At the same time, second nuts are respectively locked on both sides of the buffer assembly 50 relative to the buffer assembly positioning hole 23, so as to further fix the buffer assembly 50.

[0141] Further, a sliding through hole 24 is provided on the blocking base 20. The sliding through hole 24 matches the telescopic rod 43, and the telescopic rod 43 is slidably connected to the blocking base 20 through the sliding through hole 24, and the sliding direction of the telescopic rod 43 is consistent with the moving direction of the vehicle 70.

[0142] Further, both ends of the telescopic rod 43 along the moving direction of the vehicle 70 protrude from the blocking base 20. One end of the telescopic rod 43 is provided with a vehicle abutting end 41, and the other end of the telescopic rod 43 is fixedly connected to the positioning member 42.

[0143] Further, a strengthening structure 411 is provided on the vehicle abutting end 41. The strengthening structure 411 is wear-resistant and impact-resistant, so as to extend the service life of the telescopic rod 43 and improve the accuracy of the position sensor 30 sensing.

[0144] Further, a positioning flat is provided at one end of the telescopic rod 43 away from the vehicle 70, and a flat hole is provided on the positioning member 42. The positioning flat and the flat hole match each other. At the same time, a setscrew 130 is provided to fix the positioning member 42, so as to realize the positioning and fixation of the positioning member 42.

[0145] Specifically, the positioning member 42 is an L-shaped aluminum positioning member, which can enter or leave the position sensing area of the position sensor 30.

[0146] Further, a limiting sliding part is provided on the telescopic rod 43, and a limiting groove matching the limiting sliding part is provided on the blocking base 20. The limiting groove and the limiting sliding part can slide relative to each other.

[0147] Specifically, the limiting groove and the limiting sliding part cooperate to limit the extreme movement position of the telescopic rod 43 and limit the rotation of the telescopic rod 43. Specifically, the dimension of the limiting groove along the moving direction of the vehicle 70 is adapted to the compression amount of the vehicle 70 on the telescopic rod 43.

[0148] It should be noted that during the sliding process of the telescopic rod 43 in the sliding through hole 24, due to the cooperation and restraint of the limiting groove and the limiting sliding part, the telescopic rod 43 can only perform corresponding translational motion. During this period, there is no relative rotation between the telescopic rod 43 and the blocking base 20.

[0149] Furthermore, the limiting sliding part protrudes from the limiting groove 431.

[0150] Furthermore, the telescopic mechanism 40 further includes an elastic member 44. The elastic member 44 is sleeved on the telescopic rod 43. One end of the elastic member 44 abuts against the telescopic rod 43, and the other end of the elastic member 44 abuts against the limiting sliding part. In this way, the structural complexity of the vehicle positioning device can be reduced.

[0151] Specifically, the limiting sliding part is a second pin shaft, and the elastic member 44 is a compression spring.

[0152] Specifically, the compression spring is used for the reset of the telescopic rod 43. When the vehicle 70 pushes the telescopic rod 43 to move, the compression spring is compressed. When the vehicle 70 is lifted by the lifting mechanism 80 and moves away from the telescopic rod 43, the telescopic rod 43 returns to its initial position under the resilience of the compression spring.

[0153] Furthermore, the axial direction of the sensor fixing hole 21 is perpendicular to the movement direction of the streamline 60. There is a high-frequency impact between the vehicle 70 and the vehicle buffer end 51. In this way, the phenomenon of loosening of the position sensor 30 caused by the high-frequency impact can be minimized, thereby preventing the position sensor 30 from being damaged and improving the sensing accuracy of the position sensor 30.

[0154] Furthermore, in the movement direction of the vehicle 70, the first gap between the end of the position sensor 30 protruding from the blocking base 20 and the blocking base 20 is 7.5 mm.

[0155] Furthermore, in the direction perpendicular to the movement direction of the vehicle 70, the second gap between the positioning member 42 and the position sensor 30 is 1 mm. In this way, the position sensor 30 can be prevented from being damaged by collision.

[0156] Furthermore, the sensor fixing hole 21 is provided with internal threads, and the outer periphery of the position sensor 30 is provided with external threads. The internal threads of the sensor fixing hole 21 and the external threads of the position sensor 30 are screwed and fixed. At the same time, first nuts are locked on both sides of the position sensor 30 relative to the sensor fixing hole 21, so as to further fix the position sensor 30.

[0157] Furthermore, when there is a gap between the vehicle 70 and the vehicle abutting end 41, the positioning member 42 is away from the position sensing area of the position sensor 30; when the vehicle 70 is smoothly blocked and stopped by the buffer assembly 50, the positioning member 42 enters the position sensing area of the position sensor 30.

[0158] Specifically, the position sensor 30 is a proximity switch.

[0159] Furthermore, the vehicle positioning device further includes a jacking mechanism 80, and the jacking mechanism 80 is electrically connected to the streamline controller; the jacking mechanism 80 includes a fixedly connected jacking transmission assembly 81 and a jacking plate 82. The jacking transmission assembly 81 is fixedly connected to the streamline fixed platform 10. A jacking plate positioning portion 821 protrudes from one side of the jacking plate 82 facing the vehicle 70. Correspondingly, the first vehicle positioning portion includes a vehicle positioning hole, and the vehicle positioning hole is in clearance fit with the jacking plate positioning portion 821. In this way, the vehicle 70 is positioned to the jacking plate 82.

[0160] Furthermore, the jacking plate 82 is used to position and carry the vehicle 70.

[0161] Furthermore, there are 4 jacking plate positioning portions 821 provided on the jacking plate 82, and the jacking plate positioning portions 821 are arranged at the four corners of the jacking plate 82.

[0162] Furthermore, 4 elastic support members 822 protrude from one side surface of the jacking plate 82 facing the vehicle 70. The elastic support members 822 are used to support the vehicle 70. When the vehicle 70 is jacked up and contacts the positioning cover plate 120, the elastic support members 822 can be partially compressed so that the vehicle 70 and the positioning cover plate 120 are in full contact. In this way, the problem of poor contact between the vehicle 70 and the positioning cover plate 120 caused by the poor flatness of the jacking plate 82, the vehicle 70, and the positioning cover plate 120 can be solved, thereby improving the positioning accuracy of the vehicle 70.

[0163] Specifically, the elastic support member 822 is a cuboid support member. The protruding height of the elastic support member 822 can be 0.5 mm, and the hardness of the elastic support member 822 can be A80.

[0164] Furthermore, a special-shaped storage groove 823 is provided on one side of the jacking plate 82 facing the vehicle 70. The storage groove 823 can store small parts that accidentally fall from the vehicle 70 onto the jacking plate 82, and can also store other foreign objects that fall onto the jacking plate 82. In this way, the influence of small parts and other foreign objects that accidentally fall from the vehicle 70 onto the jacking plate 82 on the positioning accuracy of the vehicle 70 can be avoided to the greatest extent.

[0165] In Embodiment 2, the streamline driving mechanism drives the conveyor belt 61 to move. The carrier 70 is carried on the conveyor belt 61 and moves synchronously with the conveyor belt 61. When the carrier 70 moves to the lower area of the target working position, the carrier 70 abuts against and compresses the carrier buffer end 51, and the buffer assembly 50 absorbs the kinetic energy of the carrier 70, so that the carrier 70 is smoothly blocked and stopped. At the same time, the carrier 70 abuts against and pushes the carrier abutting end 41. Thus, the telescopic rod 43 drives the positioning member 42 to perform a translational motion along the sliding through hole 24, and the positioning member 42 enters the position sensing area of the position sensor 30. At this time, the position sensor 30 senses the position information of the positioning member 42 and sends the position information of the positioning member 42 to the streamline controller. This position information indicates that the carrier 70 has been smoothly blocked and stopped at the target position. Furthermore, the streamline controller controls the lifting transmission assembly 81 to perform a lifting motion. At the same time, the lifting plate 82 carries the carrier 70 and moves towards the target working position, so that the carrier 70 moves to the target working position. At this time, since the carrier 70 is away from the carrier abutting end 41, the telescopic rod 43 returns to the initial position under the action of the resilience of the elastic member 44.

[0166] The carrier positioning device in Embodiment 2 is provided with a buffer assembly 50 to absorb the kinetic energy of the carrier 70 to smoothly block and stop the carrier 70, which is beneficial to solving the problem of the carrier 70 rebounding. At the same time, a telescopic mechanism 40 is provided to indirectly transmit the position information of the carrier 70, and a position sensor 30 with a fixed direction perpendicular to the movement direction of the carrier 70 senses the position information of the positioning member 42 from the front side, which is beneficial to solving the problems that the position sensor 30 is prone to looseness and inaccurate sensing.

[0167] In addition, an elastic support member 822 is convexly provided on the lifting plate 82, which is beneficial to solving the problem of inaccurate positioning of the carrier 70 caused by incomplete contact between the carrier 70 and the positioning cover plate 120. A storage groove 823 is provided on the lifting plate 82, which can maximally avoid the influence of small parts and other foreign objects accidentally falling from the carrier 70 onto the lifting plate 82 on the positioning accuracy of the carrier 70, thereby improving the positioning accuracy of the carrier 70.

[0168] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
