[0053] As Figures 1 to 10 As shown, an embodiment of the present application provides a vehicle longitudinal beam carrier 100, which is applied to a vehicle assembly system (not shown), and includes: a lifting mechanism 1, a transfer mechanism 2, a lifting mechanism 3, and a flipping mechanism 4. Among them, the lifting mechanism 1 is relatively arranged at a first designated position of the transfer track 5 of the vehicle assembly system. Each lifting mechanism 1 contacts the end of the longitudinal beam 6 when the longitudinal beam 6 reaches the first designated position, so as to lift the longitudinal beam 6 from the previous station to a designated height. The lifting mechanism 3 is arranged on the transfer mechanism 2 and moves to the side of the lifting mechanism 1 along with the transfer mechanism 2 through the transfer track 5. The flipping mechanism 4 is arranged on the lifting mechanism 3 and is lifted to a designated height by the lifting mechanism 3. After the flipping mechanism 4 obtains the longitudinal beam 6 at the designated height, it descends to the initial position along with the lifting mechanism 3 and moves to the next station at the second designated position along with the transfer mechanism 2. The structures of each device and the connection relationships between them will be specifically described below, as follows:

[0054] In the embodiment of the present application, two lifting mechanisms 1 are provided. One of the lifting mechanisms 1 is used to contact one end of the longitudinal beam 6, and the other lifting mechanism 1 is used to contact the other end of the longitudinal beam 6 to lift or lower the longitudinal beam 6. Hereinafter, one lifting mechanism 1 will be used for explanation. The lifting mechanism 1 includes a fixed seat 11, a first driving motor 12, a guiding assembly 13, a lifting frame 14, and a first switch assembly 15. Among them, the fixed seat 11 is arranged along the transfer track 5 at a first designated position, which is the position where the longitudinal beam 6 is handed over to the lifting mechanism 1 after being produced and transported at the previous station. The transfer track 5 connects all stations of the vehicle assembly system in series. The fixed seat 11 is integrally U-shaped, including a horizontal base 111 and vertical side arms 112. The horizontal base 111 has a square structure, which can stably mount the fixed seat 11 at the first position of the transfer track 5. The vertical side arms 112 are oppositely arranged on both sides of the horizontal base 111. The fixed end of the first driving motor 12 is fixed to the fixed seat 11, and specifically, it is arranged on the mounting bracket of the horizontal base 111 of the fixed seat 11 for supporting and installing the first driving motor 12. The driving end of the first driving motor 12 is connected to the lifting frame 14 to drive the lifting and lowering actions of the lifting frame 14. The driving end of the first driving motor 12 includes a cam structure 121 connected to the output shaft of the first driving motor 12. The lifting frame 14 includes vertical side frame arms 141, a connecting component 142 connected to the driving end of the first driving motor 12, and a transverse support arm 143 for carrying the longitudinal beam 6. The vertical side frame arms 141 are located on both sides of the lifting frame 14 and are opposite to the vertical side arms 112 of the fixed seat 11. The connecting component 142 connected to the driving end of the first driving motor 12 is at the middle position of the lifting frame 14. The connecting component 142 includes a connecting rod 1421 and a protective shell 1422. The connecting rod 1421 is horizontally arranged and is arranged on an inner wall of the protective shell 1422. The cam structure 121 abuts against the connecting rod 1421 to realize the lifting and lowering actions of the lifting frame 14. The transverse support arm 143 connects the oppositely arranged vertical side frame arms 141. The upper end surface of the transverse support arm 143 has a shape for carrying the longitudinal beam 6 and is used to carry the longitudinal beam 6. Setting the lifting frame 14 as a frame structure can reduce the weight of the lifting frame 14 and facilitate the driving of the first driving motor 12.

[0055] In the embodiment of the present application, in order to enable the lifting frame 14 to move stably on the fixed seat 11, the guiding component 13 is arranged between the lifting frame 14 and the fixed seat 11, so that the lifting frame 14 moves on the fixed seat 11 through the guiding component 13. The guiding component 13 is arranged in two, and each guiding component 13 is correspondingly arranged between the vertical side frame arm 141 of the lifting frame 14 and the vertical side arm 112 of the fixed seat 11. Among them, the guiding component 13 includes a limiting guide rail 131, a moving guiding wheel 132, a limiting guiding wheel 133 and a guiding seat 134. The limiting guide rail 131 is arranged on the vertical side arm 112 of the fixed seat 11, and the guiding seat 134 is arranged on the vertical side frame arm 141 of the lifting frame 14. The vertical side frame arm 141 and the vertical side arm 112 of the fixed seat 11 are arranged opposite to each other. The moving guiding wheel 132 is arranged opposite to the limiting guide rail 131. The circumferential wheel surface of the moving guiding wheel 132 can contact the first rail surface of the limiting guide rail 131 and roll on the first rail surface of the limiting guide rail 131. The limiting guiding wheels 133 are arranged on both sides of the moving guiding wheel 132 relatively. The distance between the limiting guiding wheel 133 and the limiting guide rail 131 is smaller than the distance between the moving guiding wheel 132 and the limiting guide rail 131, that is, the limiting guiding wheel 133 is closer to the limiting guide rail 131 than the moving guiding wheel 132. The limiting guide rail 131 is located between the relatively arranged limiting guiding wheels 133. The circumferential wheel surface of the limiting guiding wheel 133 is perpendicular to the circumferential wheel surface of the moving guiding wheel 132. The circumferential wheel surface of the limiting guiding wheel 133 contacts the second rail surface of the limiting guide rail 131. The second rail surface of the limiting guide rail 131 is perpendicular to the first rail surface. The second rail surface of the limiting guide rail 131 is the two side surfaces of the limiting guide rail 131. The movement of the lifting frame 14 on the fixed seat 11 is realized through the cooperation of the moving guiding wheel 132 and the limiting guiding wheel 133 with the limiting guide rail 131.

[0056] In the embodiment of the present application, the first switch assembly 15 is disposed between the lifting frame 14 and the fixed seat 11, and executes the lifting / lowering instruction according to the positional relationship between the lifting frame 14 and the fixed seat 11. Specifically, the first switch assembly 15 includes a first switch 151 and a first signal plate 152. The first switch 151 is disposed on the fixed seat 11 at a preset height. The first signal plate 152 is disposed on the lifting frame 14 and has a first positional relationship and a second positional relationship with the first switch 151. When in the first positional relationship, the first switch 151 and the first signal plate 152 generate a lifting instruction. When in the second positional relationship, the first switch 151 and the first signal plate 152 generate a lowering instruction. Specifically, when the longitudinal beam 6 reaches the first designated position, the initial positional relationship between the first signal plate 152 and the first switch 151 is the first positional relationship. When in the first positional relationship, the first switch 151 and the first signal plate 152 generate a lifting instruction and send the lifting instruction to the first driving motor 12. The first driving motor 12 lifts the lifting frame 14 according to the lifting instruction. When the lifting frame 14 is moved to the designated height, the first signal plate 152 rises a corresponding distance along with the lifting frame 14. This distance causes the positional relationship between the position where the first signal plate 152 is located and the first switch 151 to change to the second positional relationship. When in the second positional relationship, the first switch 151 and the first signal plate 152 generate a lowering instruction and send the lowering instruction to the first driving motor 12. The first driving motor 12 lowers the lifting frame 14 according to the lowering instruction.

[0057] The above is the specific structural components and connection methods of the lifting mechanism 1. When the longitudinal beam 6 reaches the first designated position, the first switch assembly 15 sends a lifting or lowering instruction to the first driving motor 12. The first driving motor 12 drives the lifting frame 14 to lift or lower along the guiding assembly 13 to achieve the transportation of the longitudinal beam 6.

[0058] After the lifting mechanism 1 lifts the longitudinal beam 6 to a specified height, the transfer mechanism 2 moves to the side of the lifting mechanism 1 through the transfer track 5. In the embodiment of the present application, the transfer mechanism 2 includes a transfer bracket 21, a second drive motor 22, a driving wheel set 24, and a driven wheel set 25. Among them, the overall shape of the transfer bracket 21 is a cubic frame structure, which can support the loading and unloading lifting mechanism 3 and the flipping mechanism 4 while reducing the weight of the transfer bracket 21, thereby improving the transfer efficiency of the transfer bracket 21. The fixed end of the second drive motor 22 is fixedly arranged on the transfer bracket 21, and specifically, the fixed end of the second drive motor 22 is fixed on the side end face of a support arm of the transfer bracket 21 to fix the second drive motor 22 on the transfer bracket 21. The connection end 23 of the second drive motor 22 is connected to the driving wheel set 24. Specifically, the connection end 23 of the second drive motor 22 includes a first drive shaft 231 and a first connecting rotating shaft 232. The first drive shaft 231 is connected to the driving wheel set 24, and the first connecting rotating shaft 232 is connected between the first drive shafts 231. The first connecting rotating shaft 232 rotates synchronously with the first drive shaft 231. Further, in this embodiment, three first drive shafts 231 are provided. Two of the first drive shafts 231 are arranged at both ends of the output end of the second drive motor 22. Specifically, one first drive shaft 231 is connected to the driving wheel set 24, and the other first drive shaft 231 is connected to one end of the first connecting rotating shaft 232. The other end of the first connecting rotating shaft 232 is connected to the driving wheel set 24 through the third first drive shaft 231. The second drive motor 22 drives the first drive shaft 231 to drive the first connecting rotating shaft 232 to make the driving wheel set 24 rotate.

[0059] In the embodiment of the present application, the driving wheel set 24 is arranged on the first side of the traveling support 21, and the driven wheel set 25 is arranged on the second side of the traveling support 21, and the first side and the second side are opposite. Specifically, based on the fact that the traveling support 21 has a cubic structure and has four corners, each corner corresponds to a protective housing 26. The first side of the traveling support 21 includes two of the corners, and the two corners are on the same side of the traveling support 21. The second side of the traveling support 21 includes the other two corners, and the other two corners are on the same side of the traveling support 21. The driving wheel set 24 is correspondingly arranged in the protective housings 26 of the two corners on the first side of the traveling support 21, and the driven wheel set 25 is correspondingly arranged in the protective housings 26 of the two corners on the second side of the traveling support 21. Among them, the driving wheel set 24 includes a first driving gear 241 and a driving wheel 242, and the driven wheel set 25 includes a driven wheel 251. The first driving gear 241 and the driving wheel 242 are coaxially arranged on the first driving shaft 231. The first driving gear 241 meshes with the gear track 51 of the traveling track 5, and the driving wheel 242 travels on the horizontal track 52 of the traveling track 5. The driven wheel 251 and the driving wheel 242 are arranged on the same straight line, and the driven wheel 251 travels on the horizontal track 52 of the traveling track 5. The second driving motor 22 drives the driving wheel set 24 to drive the driven wheel set 25 to rotate, so that the traveling support 21 can move on the traveling track 5.

[0060] In the embodiment of the present application, in order to accurately move the traveling mechanism 2 to the first position, a second switch assembly (not marked) is further provided. The second switch assembly is arranged between the traveling support 21 and the traveling track 5, and executes a forward / backward instruction according to the positional relationship between the traveling support 21 and the traveling track 5. Specifically, the second switch assembly includes a second switch and a second signal sending board. The second switch is arranged on the traveling track 5 with a preset length, and the second signal sending board is arranged on the traveling support 21 and has a first positional relationship and a second positional relationship with the second switch. When in the first positional relationship, the second switch and the second signal sending board generate a forward instruction; when in the second positional relationship, the second switch and the second signal sending board generate a backward instruction. Specifically, when the longitudinal beam 6 reaches the first designated position, the initial positional relationship between the second signal sending board and the second switch is the first positional relationship. When in the first positional relationship, the second switch and the second signal sending board generate a forward instruction and send a forward instruction to the second driving motor 22. The second driving motor 22 moves the traveling support 21 to the first designated position according to the forward instruction. When the traveling support 21 is moved to the first designated position, the second signal sending board moves a corresponding distance relative to the initial position along with the traveling support 21, and this distance changes the positional relationship between the position where the second signal sending board is located and the second switch to the second positional relationship. When in the second positional relationship, the second switch and the second signal sending board generate a backward instruction and send a backward instruction to the second driving motor 22. The second driving motor 22 drives the traveling support 21 to move to the initial position according to the backward instruction.

[0061] In the embodiment of the present application, when the transfer mechanism 2 transfers to the first designated position, in order to obtain the longitudinal beam 6 at the designated height of the lifting mechanism 1, a lifting mechanism 3 is further provided. The lifting mechanism 3 is arranged on the transfer mechanism 2 and moves to the side of the lifting mechanism 1 along with the transfer mechanism 2 through the transfer track 5 and is lifted to the designated height. Among them, the lifting mechanism 3 includes a third driving motor 31, a belt 33, a first connecting bracket 34, a second connecting bracket 35, a cross bar 36 and a telescopic rod 37. Specifically, the first connecting bracket 34 is connected to the second connecting bracket 35 through the cross bar 36, the telescopic rod 37 is arranged and telescoped between the first connecting bracket 34 and the second connecting bracket 35, and the first connecting bracket 34 is fixedly connected to the transfer bracket 21 to move synchronously with the transfer bracket 21. The fixed end of the third driving motor 31 is fixedly connected to the first connecting bracket 34, one end of the belt 33 is connected to the output shaft 32 of the third driving motor 31, and the other end is connected to the cross bar 36. The third driving motor 31 drives the belt 33 to drive the cross bar 36 to deform so that the second connecting bracket 35 moves away from or approaches the first connecting bracket 34. When the second connecting bracket 35 moves away from the first connecting bracket 34, the cross bar 36 is in a crossed state and the telescopic rod 37 is extended and elongated; when the second connecting bracket 35 approaches the first connecting bracket 34, the cross bar 36 returns to its original position and the telescopic rod 37 is compressed.

[0062] After the third driving motor 31 lifts the second connecting bracket 35, it is necessary to remove the longitudinal beam 6 at the designated height from the lifting mechanism 1 through the flipping mechanism 4. Among them, the flipping mechanism 4 is arranged on the lifting mechanism 3, and specifically is arranged on the second connecting bracket 35 of the lifting mechanism 3 and is lifted to the designated height by the lifting mechanism 3. After the flipping mechanism 4 obtains the longitudinal beam 6 at the designated height, it descends to the initial position along with the lifting mechanism 3 and moves to the second designated position along with the transfer mechanism 2. Specifically, in the embodiment of the present application, the flipping mechanism 4 includes a support frame 41, a fourth driving motor 42, an angle flipping assembly 43 and a clamping arm 48. Among them, the support frame 41 is fixedly connected to the second connecting bracket 35 to arrange the flipping mechanism 4 on the lifting mechanism 3. The fixed end of the fourth driving motor 42 is fixedly connected to the support frame 41, the output end of the fourth driving motor 42 is connected to the clamping arm 48 through the angle flipping assembly 43, and the clamping arms 48 are oppositely arranged at the opposite ends of the support frame 41. The fourth driving motor 42 drives the angle flipping assembly 43 to rotate the clamping arm 48, and the clamping arm 48 is used to clamp the longitudinal beam 6.

[0063] Further, in the embodiment of the present application, the angle flipping assembly 43 includes a second driving gear 44, a sector gear 45, a rotating shaft 46, and a second connecting rotating shaft 47. Among them, the rotating shaft 46 is fixedly connected to the oppositely arranged clamping arms 48 respectively, the second connecting rotating shaft 47 is arranged between the rotating shafts 46, and the second connecting rotating shaft 47 rotates synchronously with the rotating shaft 46. The second driving gear 44 is connected to the output end of the fourth driving motor 42, the sector gear 45 is fixedly connected to the rotating shaft 46, the rack of the sector gear 45 meshes with the second driving gear 44, and the output end of the fourth driving motor 42 drives the second driving gear 44, so that the sector gear 45 drives the rotating shaft 46 to rotate, thereby causing the clamping arms 48 to rotate.

[0064] In the embodiment of the present application, in order to accurately control the rotation angle of the clamping arm 48 so that the clamping arm 48 obtains the longitudinal beam 6 at a specified height, the angle flipping assembly 43 further includes an angle detector 49. The angle detector 49 is square and is arranged on the rotating shaft 46 at a preset angle to rotate synchronously with the rotating shaft 46. When the lifting mechanism 3 is lifted to the specified height, the angle detector 49 rotates 90 degrees (clockwise) with the rotating shaft 46, so that the clamping arm 48 clamps and obtains the longitudinal beam 6 on the lifting mechanism 1 at a rotation angle of 90 degrees. Then, the flipping mechanism 4 descends to the initial position with the lifting mechanism 3 and moves to the next working station at the second specified position with the traveling mechanism 2. At the same time, the lifting frame 14 of the lifting mechanism 1 descends. After waiting for the next longitudinal beam 6 to arrive, the first driving motor 12 of the lifting mechanism 1 drives the lifting frame 14 to rise again and lift the longitudinal beam 6 to the specified height. At the second specified position, the longitudinal beam 6 is taken to the next working station where the second specified position is located. At this time, the angle detector 49 of the flipping mechanism 4 rotates 90 degrees (counterclockwise) with the rotating shaft 46, so that the clamping arm 48 rotates to the initial position at a rotation angle of 90 degrees. Then, the traveling mechanism 2 drives the lifting mechanism 3 and the flipping mechanism 4 to move to the side of the lifting mechanism 1 again, and the flipping mechanism 4 is lifted to the specified height again by the lifting mechanism 3. After the flipping mechanism 4 obtains the next longitudinal beam 6 at the specified height, it descends to the initial position with the lifting mechanism 3 and moves to the next working station at the second specified position with the traveling mechanism 2 again. It should be noted that the transported longitudinal beam 6 can be a single longitudinal beam 6 or a group of longitudinal beams 6, and a group of longitudinal beams 6 includes multiple longitudinal beams 6.

[0065] The present application provides the following scenario embodiments. Specifically, when the longitudinal beam 6 is transported to the first position by a transport device (generally a transport chain capable of carrying the longitudinal beam), the lifting mechanism 1 drives the lifting frame 14 to lift the longitudinal beam 6 from the transport device through the first drive motor 12, so that the longitudinal beam 6 is separated from the transport device. At the same time, the transfer mechanism 2 drives the lifting mechanism 3 and the flipping mechanism 4 to move to the side of the lifting mechanism 1 through the transfer track 5. The lifting mechanism 3 lifts the flipping mechanism 4 to a certain height, so that the flipping mechanism 4 can take out the longitudinal beam 6 on the lifting frame 14. Then, the transfer mechanism 2 drives the lifting mechanism 3 and the flipping mechanism 4 to move to the second designated position through the transfer track 5. The second designated position is the position where the suspension chain hook moves in real time. The transfer mechanism 2 can obtain the position information of the movement of the suspension chain hook in real time and adjust the self-transfer speed of the transfer mechanism 2 accordingly to move to the lower part of the suspension chain hook. At this time, the lifting mechanism 3 lifts the flipping mechanism 4 to a certain height, so that the flipping mechanism 4 can transfer the longitudinal beam 6 to the suspension chain hook by flipping and rotating an angle. The suspension chain hook transports the longitudinal beam 6 to the designated position, and the transfer mechanism 2 continues to drive the lifting mechanism 3 and the flipping mechanism 4 to move to the side of the lifting mechanism 1 through the transfer track 5. The lifting mechanism 3 lifts the flipping mechanism 4 to a certain height, so that the flipping mechanism 4 can take out the next longitudinal beam 6 on the lifting frame 14.

[0066] An embodiment of the present application provides a vehicle longitudinal beam carrying device 100, including: a lifting mechanism 1, a transfer mechanism 2, a lifting mechanism 3 and a flipping mechanism 4; the lifting mechanism 1 is oppositely arranged at the first designated position of the transfer track 5 of the vehicle assembly system, and each lifting mechanism 1 contacts the end of the longitudinal beam 6 when the longitudinal beam 6 reaches the first designated position to lift the longitudinal beam 6 from the previous work station to the designated height; the lifting mechanism 3 is arranged on the transfer mechanism 2 and moves to the side of the lifting mechanism 1 through the transfer track 5 along with the transfer mechanism 2. The flipping mechanism 4 is arranged on the lifting mechanism 3 and is lifted to the designated height by the lifting mechanism 3. After the flipping mechanism 4 obtains the longitudinal beam 6 at the designated height, it descends to the initial position along with the lifting mechanism 3 and moves to the next work station at the second designated position along with the transfer mechanism 2.

[0067] In the embodiment of the present application, the lifting mechanism 1 lifts the longitudinal beam 6 from the previous work station to the designated height, and the transfer mechanism 2 drives the lifting mechanism 3 and the flipping mechanism 4 to move to the side of the lifting mechanism 1. Then, the lifting mechanism 3 and the flipping mechanism 4 take the longitudinal beam 6 at the designated height to the flipping mechanism 4 and then move to the next work station at the second designated position along with the transfer mechanism 2. The process of transporting the longitudinal beam 6 is all carried out in an automated manner, thereby reducing the labor intensity of the staff while also improving the transportation efficiency of the vehicle longitudinal beam 6.
