DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In the present invention, for the convenience of description, the description of the relative position relationship of each component is described according to the layout of the drawings in the specification, such as: the position relationship of front, back, up, down, left, right, etc. is determined according to the layout direction of the description.

[0021] See also Figure 1-5, the present invention provides the following technical solutions: A linear inclined lifting and positioning mechanism, comprising a base 1 and a lifting bottom plate 2. At the top of the base 1, support columns 11 distributed in a rectangle are fixedly connected. The other end of the support column 11 is fixedly connected to the lifting bottom plate 2. On the left side of the top of the base 1, a blocking cylinder 12 is fixedly connected. The blocking cylinder 12 is pneumatically connected to an external air source. At the output end of the blocking cylinder 12, a stopper 121 is fixedly connected. At the lower end face of the lifting bottom plate 2, a lifting cylinder 21 is fixedly connected. The lifting cylinder 21 is pneumatically connected to an external air source. At the output end of the lifting cylinder 21, a connecting rod 211 is fixedly connected. The connecting rod 211 extends upward through the lifting bottom plate 2 to the outside of the lifting bottom plate 2. Above the lifting bottom plate 2, a positioning plate 3 is provided. Inside the positioning plate 3, a rotating shaft 33 is rotatably connected. Both ends of the rotating shaft 33 penetrate through the positioning plate 3 and extend to the outside of the positioning plate 3. On the left and right sides of the upper end face of the lifting bottom plate 2, linear bearings 22 are fixedly connected respectively. Both ends of the rotating shaft 33 are respectively engaged with the two linear bearings 22. Inside one side wall of the positioning plate 3, two symmetrically distributed connecting blocks 34 are fixedly connected. On the upper end face of the lifting bottom plate 2, two springs 24 are fixedly connected. The two springs 24 are respectively located directly below the two connecting blocks 34. At the top of the spring 24, a spring cover 241 is fixedly connected. At the top of the spring cover 241, a guide post 242 is fixedly connected. The guide post 242 is rotatably connected to the connecting block 34. On both the left and right sides of the positioning plate 3, two limiting grooves 35 are opened. The limiting grooves 35 are located at the connection between the rotating shaft 33 and the positioning plate 3. On both sides of the outer walls of both ends of the rotating shaft 33, rotating limit pins 331 are fixedly connected. The rotating limit pins 331 are located inside the limiting grooves 35.

[0022] In this embodiment, the base 1 and the lifting bottom plate 2 are connected by four support columns 11 to improve the stability of the structure. When the carrier is transported, the carrier flows to the lifting position through the assembly line, and the in-place sensor 23 works to sense the carrier. The in-place sensor 23 is a contact sensor. When the carrier touches the travel switch during movement, its internal contact will move to complete the control. The model of the in-place sensor 23 is D5C. After the in-place sensor 23 senses that the carrier is in place, the blocking cylinder 12 pushes the block 121 upward. The block 121 moves upward to a position higher than the positioning plate 3. The carrier is blocked by the block 121 to prevent the carrier from moving too much. The block 121 After blocking, the lifting cylinder 21 pushes the connecting rod 211 upward, and the top end of the connecting rod 211 is fixed inside the through hole 333 inside the rotating shaft 33. The connecting rod 211 pushes the positioning plate 3 upward, and the positioning plate 3 lifts the carrier upward. The positioning pins 31 at both ends of the positioning plate 3 are used to position the carrier. The linear bearings 22 at both ends of the positioning plate 3 guide the positioning plate 3 during the upward movement, so that the positioning plate 3 keeps rising linearly. Two connecting blocks 34 are provided on the other side of the positioning plate 3. The connecting block 34 is internally rotatably connected with a guide column 242. The other end of the guide column 242 is connected to a spring cover 241, which is fixed on the spring 24. The rising of the connecting rod 211 drives the positioning plate When the positioning plate 3 rises, the positioning plate 3 is pushed up by the connecting rod 211, and the spring 24 is stretched upward. The guide column 242 at the top of the spring 24 will pull the positioning plate 3 when the positioning plate 3 rises. The positioning plate 3 will tilt outside the rotating shaft 33 under the pulling of the guide column 242. After the positioning plate 3 tilts, the spring 24 will rebound. The guide column 242 pulls the positioning plate 3 downward to tilt at a certain angle. The spring 24 is guided by the spring cover 241 when stretching and rebounding, so as to avoid the spring 24 from tilting at different angles when stretching or rebounding, which affects the normal operation of the device. When the carrier is rotated during the transportation process, the carrier is blocked by pushing the stopper 121 upward by the blocking cylinder 12, and the lifting gas The cylinder 21 pushes the positioning plate 3 upward to lift the carrier. When the positioning plate 3 rises, the guide column 242 pulls the positioning plate 3 downward, and the positioning plate 3 rotates a certain angle outside the rotating shaft 33, so that the carrier does not need to be stopped and positioned before rotating during the transportation process, thereby improving the transportation efficiency. When the positioning plate 3 rotates, the limit grooves 35 at both ends of the positioning plate 3 rotate accordingly, and the limit grooves 35 rotate outside the rotation limit pin 331. The positioning plate 3 stops rotating after the bottom of the limit groove 35 contacts the rotation limit pin 331. The angle is limited by the limit groove 35 to achieve the purpose of rotating and tilting the carrier. The device structure is completely installed on the base 1, the structure is compact, space is saved, and the complexity of the mechanism is reduced.

[0023] Specifically, an in-place sensor 23 is fixedly connected to the upper end surface of the jacking base plate 2, and the in-place sensor 23 is electrically connected to an external power supply. The in-place sensor 23 is located between the stop block 121 and the positioning plate 3; after the assembly line transports the carrier to the jacking position, an in-place sensor 23 is arranged between the stop block 121 and the positioning plate 3. After the in-place sensor 23 senses that the carrier is in place, the blocking cylinder 12 pushes the stop block 121 upward to block the carrier, so as to facilitate the positioning of the carrier during the transportation of the carrier and avoid excessive movement of the carrier to affect normal operation.

[0024] Specifically, grooves 332 are provided at the bottom of both ends of the rotating shaft 33, and the width of the grooves 332 is greater than the width of the top of the linear bearing 22, and the grooves 332 are engaged and connected with the linear bearing 22; the top of the linear bearing 22 is stuck in the groove 332, so that the rotating shaft 33 and the two linear bearings 22 can be connected, and when the positioning plate 3 moves upward, it is guided by the linear bearing 22, so that the positioning plate 3 maintains a linear upward state during the movement, thereby improving the stability of the movement of the positioning plate 3.

[0025] Specifically, two symmetrically distributed positioning pins 31 are fixedly connected to the upper end surface of the positioning plate 3 ; when the positioning plate 3 lifts the carrier upward, the positioning pins 31 on both sides are used to position the carrier.

[0026] Specifically, a through hole 333 is opened in the middle of the rotating shaft 33, and the top end of the connecting rod 211 is fixedly connected to the inside of the through hole 333; the connecting rod 211 is located inside the through hole 333, and the jacking cylinder 21 and the positioning plate 3 are connected together through the connecting rod 211, and the positioning plate 3 is lifted upward by the jacking cylinder 21 during operation.

[0027] Specifically, four magnets 32 are fixedly connected to the top of the positioning plate 3, and the four magnets 32 are respectively located at the four corners of the positioning plate 3; when the lifting cylinder 21 lifts the positioning plate 3 upward, the magnets 32 can adsorb the carrier on the positioning plate 3, and when the positioning plate 3 rotates, the carrier can be firmly adsorbed on the positioning plate 3, thereby preventing the carrier from sliding down after the positioning plate 3 rotates and tilts, thereby improving the stability of the carrier when rotating.

[0028] The working principle and use process of the present invention are as follows: when the carrier is being transported, the carrier flows to the lifting position through the assembly line. After the in-place sensor 23 senses that the carrier is in place, the blocking cylinder 12 pushes the block 121 upward, and the block 121 moves upward to a position higher than the positioning plate 3 to block the carrier to prevent the carrier from moving too much. After the block 121 blocks the carrier, the lifting cylinder 21 pushes the connecting rod 211 upward to rise, and the connecting rod 211 lifts the positioning plate 3 upward, and the positioning plate 3 lifts the carrier upward. The positioning pins 31 at both ends of the positioning plate 3 position the carrier, and the magnets 32 on the top of the positioning plate 3 adsorb the carrier to improve the stability of the carrier when it rotates. During the upward movement of the positioning plate 3, it is guided by the linear bearings 22 at both ends to keep the positioning plate 3 rising in a straight line. When the connecting rod 211 is pushed upward, the spring 24 is stretched upward, and the guide column 242 at the top of the spring 24 will pull the positioning plate 3 when the positioning plate 3 rises. The positioning plate 3 will tilt outside the rotating shaft 33 under the pull of the guide column 242. After the positioning plate 3 tilts, the spring 24 rebounds, and the guide column 242 pulls the positioning plate 3 downward to tilt a certain angle. When the positioning plate 3 rotates, the limit grooves 35 at both ends of the positioning plate 3 rotate outside the rotation limit pin 331. After the bottom of the limit groove 35 contacts the rotation limit pin 331, the positioning plate 3 stops rotating. The rotation angle is limited by the limit groove 35 to achieve the purpose of rotating and tilting the carrier. The carrier can be rotated during the carrier transportation process, and there is no need to stop the carrier for positioning before rotating, thereby improving the transportation efficiency.
