Traditional conveyor systems often suffer from issues such as inaccurate positioning and unstable lifting and lowering, which not only impacts production efficiency but can also damage products. These issues are particularly prominent in applications requiring precise control of product position and height, such as precision machining and electronics assembly. However, some companies still rely on manual product handling, which can lead to injuries to products or workers due to fatigue or improper handling, resulting in inefficient production.

It can be seen that the conveyor line assembly 1 supports and limits the lifting assembly 2 and the product pallet, and the conveyor line assembly 1 plays a role in carrying the product pallet. The product pallet is transported by the conveyor line assembly 1 and limited and matched with the lifting assembly 2, and the lifting assembly 3 plays a role in lifting and lowering the conveyor line assembly 1, the lifting assembly 2 and the product pallet, making it convenient for the next workstation to grab it.

[0022] like Figure 2 and Figure 3 In the present embodiment, the conveyor line assembly 1 includes a conveyor line frame 10, a servo motor 11 and a roller 12. The conveyor line frame 10 is limited and matched with an external device. The rear end of the conveyor line frame 10 slides with the lifting assembly 2. The servo motor 11 is installed on one side of the conveyor line frame 10. A roller 12 is provided on the front end of the conveyor line frame 10. The working end of the servo motor 11 is connected and matched with the roller 12. The servo motor 11 drives the two ends of the roller 12 to rotate and match on the conveyor line frame 10. The product tray slides with the conveyor line frame 10 through the roller 12. It can be seen that the front end of the conveyor line frame 10 supports and limits the servo motor 11 and the roller 12. At the same time, the rear end of the conveyor line frame 10 connects with the lifting assembly 3. The servo motor 11 provides power to the roller 12 to transport the product tray to the top of the lifting assembly 2 or to the outside of the conveyor line frame 10.

[0023] like Figure 4In this embodiment, the lifting assembly 2 includes an adjustable lifting frame 20 and a lifting cylinder 21. The adjustable lifting frame 20 is provided with a plurality of support blocks 22 and positioning components. The two ends of the adjustable lifting frame 20 are limited and matched inside the conveyor line assembly 1. The lifting cylinder 21 is installed at the lower end of the adjustable lifting frame 20. The support block 22 and the positioning component are both installed on the top surface of the adjustable lifting frame 20. The support block 22 and the positioning component are both limited and matched with the product tray. The movable end of the lifting cylinder 21 passes through the adjustable lifting frame 20 and matches with the product tray. It can be seen that the adjustable lifting frame 20 supports and fixes the lifting cylinder 21, the support block 22 and the positioning component. The lifting cylinder 21 drives the movable plate on the adjustable lifting frame 20 to lift the product tray. The support block 22 and the positioning component both limit and position the product tray.

[0024] like Figure 5 In the present embodiment, the lifting assembly 3 includes a lifting fixed plate 30, a lifting cylinder 31, a pair of slide rails 32 and a lifting limit component. The pair of slide rails 32, the lifting cylinder 31 and the lifting limit component are all mounted on the lifting fixed plate 30. The slide rails 32 are in sliding cooperation with the conveyor line assembly 1, and the movable end of the lifting cylinder 31 is connected and cooperated with the conveyor line assembly 1. It can be seen that the lifting fixed plate 30 supports and limits the lifting cylinder 31, the pair of slide rails 32 and the lifting limit component. The slide rails 32 help the conveyor line assembly 1 to slide and guide on the lifting fixed plate 30. At the same time, the slide rails 32 also help the conveyor line assembly 1 to limit left and right. The lifting limit component helps the conveyor line assembly 1 to limit up and down when the lifting fixed plate 30 slides.

[0025] like Figure 1 As mentioned above, in this embodiment, a drag chain 9 is provided between the conveyor line assembly 1 and the lifting assembly 3. The two ends of the drag chain 9 are mounted on the conveyor line assembly 1 and the lifting assembly 3. The drag chain 9 cooperates with the position limits of several pipeline lines. Thus, it can be seen that the conveyor line assembly 1 and the lifting assembly 3 both support and fix the drag chain 9. The drag chain 9 also serves as a position limiter and protector for the line channels and other components on the conveyor line lifting and positioning mechanism, preventing cables, pipelines, etc. from being damaged due to movement or friction when the mechanical equipment is in operation.

[0026] like Figure 2 and Figure 3In this embodiment, the conveyor line frame 10 is provided with a sensor 13 and a stop block 14. The sensor 13 is inductively matched with the product pallet. The stop block 14 is fixedly matched with the rear end of the conveyor line frame 10. The stop block 14 is inductively matched with the product pallet that is slidably matched on the conveyor line frame 10. It can be seen that the conveyor line frame 10 supports and limits the sensor 13 and the stop block 14. The sensor 13 detects the position of the product pallet and detects whether the product pallet is transported by the conveyor line frame 10 to the lifting assembly 2. The stop block 14 limits the product pallet transported by the conveyor line frame 10, so that the product pallet stays above the lifting assembly 2 and waits for the lifting assembly 2 to limit the position.

[0027] like Figure 2 and Figure 3 In this embodiment, the left and right sides of the lower surface of the conveyor line frame 10 are provided with reinforcing ribs 15, and a connecting shaft 16 is provided between a pair of the reinforcing ribs 15 near the front end of the conveyor line frame 10. The two ends of the connecting shaft 16 are respectively limited by the pair of reinforcing ribs 15. It can be seen that the conveyor line frame 10 supports and fixes the reinforcing ribs 15 and the connecting shaft 16. The reinforcing ribs 15 increase the strength and rigidity of the structure of the conveyor line frame 10, so that the conveyor line frame 10 can support the lifting assembly 2. The connecting shaft 16 connects the pair of reinforcing ribs 15, so that the ends of the pair of reinforcing ribs 15 away from the lifting assembly 3 can be connected to each other, thereby increasing the stability and support strength of the overall structure, and preventing the end of the pair of reinforcing ribs 15 away from the lifting assembly 3 from being unable to be limitedly constrained, resulting in low overall structural stability and causing the product tray to fall.

[0028] like Figure 4In this embodiment, the adjustable jacking frame 20 includes a jacking fixed plate 200, a jacking movable plate 201, a plurality of guide columns 202, a plurality of linear bearings 203 and a pair of connecting plates 204, and the connecting plate 204 is provided with a plurality of adjustable limit blocks 205 and a plurality of high-strength rubber buffer blocks 206. One end of the guide column 202 is fixed on the jacking movable plate 201, and the other ends of the two guide columns 202 are connected and cooperated with the high-strength rubber buffer blocks 206. A plurality of linear bearings 203 are fixed on the jacking fixed plate 200, and the linear bearings 203 are slidably cooperated with the guide columns 202. The adjustable limit block column 205 is limitedly cooperated with the lower surface of the jacking fixed plate 200. It can be seen from this that the jacking fixed plate 200 supports and fixes the several linear bearings 203, the linear bearings 203 guide the guide columns 202, the guide columns 202 connect the jacking movable plate 201 and a pair of connecting plates 204, the connecting plates 204 connect the adjacent guide columns 202 on one side, so that the guide columns 202 on one side can be lifted and lowered together, and the connecting plates 204 also support and fix the several adjustable limit stops 205, and the adjustable limit stops 205 limit the downwardly moving jacking movable plate 201. At the same time, the height of the limit stops 205 can be adjusted to adapt to product pallets of different heights, and the rubber buffer block 206 provides a buffering effect for the guide columns 202 to avoid damage to product pallets or components due to collision.

[0029] like Figure 5 In this embodiment, the lifting and limiting components include a pair of lifting stop posts 33 and a plurality of stop screws 34. The pair of lifting stop posts 33 are installed at the upper and lower ends of the lifting fixed plate 30, and the plurality of stop screws 34 are respectively provided at the two ends of the pair of slide rails 32. The lifting stop posts 33 are limited in position with the conveyor line assembly 1, and the stop screws 34 are limited in position with the slide rails 32. It can be seen that the lifting fixed plate 30 supports and fixes the pair of lifting stop posts 33 and the plurality of stop screws 34, and the pair of lifting stop posts 33 serve as upper and lower limiters for the conveyor line assembly 1 that slides up and down, and the plurality of stop screws 34 serve as upper and lower limiters for the conveyor line assembly 1 that slides on the slide rails 32.

[0030] like Figure 3 and Figure 4In this embodiment, the positioning components include a cylindrical pin 23 and a diamond-shaped pin 24, each mounted on the lifting plate 201. Both the cylindrical pin 23 and the diamond-shaped pin 24 cooperate with the product tray to limit its position. Thus, the lifting plate 201 supports and secures the cylindrical pin 23 and the diamond-shaped pin 24, while the cylindrical pin 23 and the diamond-shaped pin 24 provide positioning, vertical movement, and rotational control for the product tray.

[0031] In this embodiment, the working principle of the utility model is as follows:

[0032] like Figures 1 to 5 As shown, the conveyor line lifting and positioning mechanism is started, the servo motor 11 drives the roller 12 to rotate, and the product tray is driven by the roller 12 to flow into the top of the lifting component 2, and the lifting cylinder 21 lifts the adjustable lifting frame 20, and the cylindrical pin 23 and the diamond pin 24 position the product. The grasping robot grasps the product and lifts the product to a safe position, and the empty product tray is driven to descend by the lifting cylinder 31, and the lifting cylinder 21 descends the adjustable lifting frame 20, and the servo motor 11 drives the roller 12 to rotate in the opposite direction, and the empty product tray is driven by the roller 12 to flow into the next station.
