[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0028] Example 1
[0029] Please refer to Figure 1 , Figure 2 and Figure 3 A multi-station lifting device includes a mounting frame 1, with a connecting frame 2 inside the mounting frame 1. The connecting frame 2 is slidably connected to the interior of the mounting frame 1. A telescopic component 3 drives the connecting frame 2 and the placement roller table 5 to move up and down. The telescopic component 3 is located on one side of the connecting frame 2, and a pulling component 4 is located on the other side of the connecting frame 2. The pulling component 4 is used to cooperate with the telescopic component 3 to drive the connecting frame 2 to move up and down more stably. The top of the connecting frame 2 is provided with a placement roller table 5, which is used to place workpieces. Both sides of the top of the placement roller table 5 are provided with protective components 8, which are used to guide the workpieces to the middle above the placement roller table 5. The interior of the placement roller table 5 is provided with two lifting components 6, which are used to drive a rotating component 7 to move up and down, thereby blocking the workpieces moving on the placement roller table 5. The top of the lifting component 6 is provided with a rotating component 7.
[0030] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the roller placement table 5 includes two connecting plates 51 fixed to the top of the connecting frame 2. A plurality of conveying rollers 52 are rotatably arranged between the two connecting plates 51. When the workpiece moves to the plurality of conveying rollers 52 through the conveying equipment on the production line, the workpiece slides on the plurality of conveying rollers 52 through the rotational connection of the conveying rollers 52 and is blocked by the rotating component 7.
[0031] Furthermore, such as Figure 3 and Figure 4As shown, the lifting component 6 is fixed to the fixing plate 62 at the bottom of the two connecting plates 51. The two fixing plates 62 are respectively fixed to the front and rear sides of the bottom of the connecting plates 51. The bottom of the fixing plate 62 is fixed with a second cylinder 61. When the second cylinder 61 is activated, it drives the rotating component 7 to move up and down. The top of the fixing plate 62 is provided with a mounting plate 64, which is used to connect with the rotating component 7. The output end of the second cylinder 61 passes through the fixing plate 62 and is fixedly connected to the mounting plate 64. Both sides of the second cylinder 61 are provided with sliding rods 63. The top of the sliding rods 63 passes through the fixing plate 62 and is fixedly connected to the mounting plate 64. When the second cylinder 61 is activated, it drives the rotating component 7 to move up and down, causing the sliding rods 63 to slide on the fixing plate 62, thereby increasing the stability of the rotating component 7 when it moves up and down.
[0032] When the workpiece moves from the front, the second cylinder 61 located at the rear is activated to raise the rotating component 7 located at the rear; the reverse is true when the workpiece moves from the rear.
[0033] Furthermore, such as Figure 3 and Figure 4 As shown, the rotating assembly 7 includes a second support plate 74 fixed to one side of the mounting plate 64, and a first support plate 73 fixed to the other side of the mounting plate 64. A motor 71 is fixed to the side of the first support plate 73 away from the mounting plate 64. By starting the motor 71, the transmission roller 72 is driven to rotate. The transmission roller 72, located above the mounting plate 64, is rotatably positioned between the second support plate 74 and the first support plate 73. The transmission roller 72 is located in the gap between the conveying rollers 52. When the second cylinder 61 is started, the transmission roller 72 is driven to rise, thereby exceeding the height of the conveying rollers 52, so as to block the workpiece moving on the conveying rollers 52. When the transmission roller 72 rotates, it drives the workpiece on the conveying rollers 52 to move, so that it is removed from the top of the placement roller table 5. The output end of the motor 71 passes through the first support plate 73 and is fixedly connected to the transmission roller 72.
[0034] Example 2
[0035] The multi-station lifting device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 and Figure 2 As shown, the telescopic assembly 3 includes a first cylinder 31 fixed inside the mounting frame 1 at the bottom end located on one side of the connecting frame 2. A connecting rod 32 is fixedly provided at the output end of the first cylinder 31. When the first cylinder 31 is activated, it drives the connecting rod 32 to move up and down. The front and rear ends of the connecting rod 32 are both provided with first synchronous pulleys 33. Two first synchronous belts 34 are fixedly provided on one side of the connecting frame 2. The ends of the first synchronous belts 34 pass around the first synchronous pulleys 33 and are fixedly connected to the bottom end inside the mounting frame 1. When the connecting rod 32 moves up and down, the first synchronous pulleys 33 are rotated through the first synchronous belts 34, thereby driving the connecting frame 2 and the placement roller table 5 to move up and down.
[0036] Furthermore, such as Figure 1 and Figure 2 As shown, the pulling assembly 4 includes two second-order synchronous belts 44 fixed to the bottom of the connecting frame 2 near the first cylinder 31. Two second-order synchronous pulleys 41 are rotatably provided inside the bottom of the mounting frame 1 near the first cylinder 31. Two third-order synchronous pulleys 42 are rotatably provided inside the bottom of the mounting frame 1 on the other side of the connecting frame 2. Two fourth-order synchronous pulleys 43 are rotatably provided inside the top of the mounting frame 1 on the other side of the connecting frame 2. The second-order synchronous pulleys 41, 3, and 43 are used to drive the other side of the connecting frame 2 to move up and down through the second-order synchronous belts 44 when the connecting frame 2 moves. The end of the second-order synchronous belt 44 passes around the second-order synchronous pulleys 41, 3, and 43 in sequence and is fixedly connected to the other side of the top of the connecting frame 2. When the first cylinder 31 is started, one side of the connecting frame 2 is pulled through the first-order synchronous belt 34, causing the connecting frame 2 to move and drive the second-order synchronous belt 44 to pull the other side of the connecting frame 2.
[0037] Example 3
[0038] The multi-station lifting device provided in Embodiments 1 and 2 has been further optimized, such as... Figure 4 As shown, the rotating assembly 7 also includes a buffer pad 75 fixed to the outside of the transmission roller 72. When it is necessary to block the workpiece moving from the front, the second cylinder 61 located at the rear is activated to raise the transmission roller 72 at its top. The workpiece is buffered by the buffer pad 75 and blocked. At this time, it is driven to rise by the telescopic assembly 3 and the pulling assembly 4. Activating the second cylinder 61 located at the front can drive the transmission roller 72 to rise, lifting the front side of the workpiece and causing the front of the workpiece to tilt up. The rear of the workpiece is blocked by the transmission roller 72 that originally blocked its movement, so that the center of gravity of the workpiece is moved to the rear, thereby preventing the workpiece from moving back and forth and preventing the workpiece from falling off the placement roller table 5.
[0039] Furthermore, such as Figure 1 and Figure 3 As shown, the protective component 8 includes a mounting base 81 fixed to the top of the connecting plate 51. A guide plate 82 is fixedly provided on the side of the mounting base 81 near the conveying roller 52. The front and rear ends of the guide plate 82 are provided with inclined surfaces near the conveying roller 52. When the workpiece moves onto the conveying roller 52, it is guided to the middle position by contacting the inclined surfaces of the guide plate 82, thereby calibrating its position. At the same time, it blocks the two sides of the workpiece to play a protective role.
[0040] The multi-station lifting device provided by this utility model is used as follows:
[0041] When a workpiece needs to be placed on the placement roller table 5, the workpiece is conveyed from the front to several conveyor rollers 52 by the production line's conveying equipment. The second cylinder 61 located at the rear is activated to raise the mounting plate 64 and the rotating assembly 7. The workpiece's inertia drives the conveyor rollers 52 to rotate, causing the workpiece to slide on the several conveyor rollers 52. When the workpiece moves a certain distance on the placement roller table 5, it is blocked by the rear transmission roller 72, and the impact force of the workpiece movement is buffered by the buffer pad 75, causing the workpiece to stop. Then, the second cylinder 61 located at the front is activated to raise the rotating assembly 7 a certain distance, tilting the front of the workpiece up, and the rear is blocked by the rear rotating assembly 7, thereby restricting the workpiece and preventing it from shifting on the placement roller table 5.
[0042] When it is necessary to move the workpiece on the placement roller table 5 upward so that the placement roller table 5 can be connected to the conveying equipment located above in the production line, the first cylinder 31 is activated, which causes the first synchronous belt 34 to move one side of the connecting frame 2 upward through the connecting rod 32 and the first synchronous pulley 33. At the same time, the connecting frame 2 moves upward through the second synchronous belt 44, so that the two sides of the connecting frame 2 can be stably stressed and rise, thereby driving the workpiece on the placement roller table 5 to rise.
[0043] When it is necessary to move the workpiece away from the placement roller table 5, the second cylinder 61 is started to move the rotating component 7 downward so that the tilted workpiece is in a flat position. At the same time, one of the buffer pads 75 can contact the bottom of the workpiece. Then the motor 71 is started to work with several conveying rollers 52 to move the workpiece away from the placement roller table 5.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
