[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1 to 4The present invention provides the following technical solution: like Figure 1 As shown, a return flow assembly line structure with a lifting function includes a support beam 1 and a mounting frame 2. The support beam 1 and the mounting frame 2 form a support frame, and a transport component for transporting workpieces is mounted on the top of the support beam 1. Figure 1 and Figure 4 As shown, there are two supporting beams 1, which are arranged vertically. There are two mounting frames 2, which are located at the two ends of the two supporting beams 1 and are arranged at an angle. A lifting assembly is installed inside the mounting frame 2. The lifting assembly includes a guide groove 3 fixedly connected inside the mounting frame 2. Two support rods 5 are slidably connected inside the guide groove 3. A lifting tray 4 is fixedly connected to the top of the support rods 5. The support rods 5 are arranged vertically, and the lifting tray 4 is arranged vertically at the top of the support rods 5.

[0021] like Figure 2 and Figure 3 As shown, two guide rods 9 are fixedly connected inside the guide groove 3 and are symmetrically distributed along its length. The lower end of the support rod 5 is slidably connected to the outside of the guide rod 9. A lifting cylinder 10 is fixedly connected in the middle of the upper end of the guide groove 3 and is distributed along its length. The telescopic end of the lifting cylinder 10 extends into the guide groove 3 and is fixedly connected in the middle of the two support rods 5.

[0022] like Figure 3 and Figure 4 As shown, the inner side of the lifting tray 4 is rotatably connected with equally spaced driven rollers 6. The side of the lifting tray 4 away from the supporting beam 1 is fixedly connected with two symmetrically distributed baffles 7, and a detector 8 is provided in the middle of the baffles 7. The outer sides of the two mounting brackets 2 are fixedly connected with ejector cylinders 11. The two ejector cylinders 11 are respectively aligned with the ends of the two transport components, and the two ejector cylinders 11 are distributed vertically.

[0023] The support beam 1 and the mounting frame 2 constitute a stable support frame. The transport assembly installed on the top of the support beam 1 is used for horizontal transport of the workpiece. When the workpiece needs to be lifted or lowered from one level to another, the lifting assembly starts to work.

[0024] The guide groove 3 inside the mounting bracket 2 provides a sliding track. Symmetrically distributed guide rods 9 are fixed inside the guide groove 3. The lower end of the support rod 5 is slidably connected to the outside of the guide rod 9, allowing the support rod 5 to move linearly along the guide rod 9. The lifting cylinder 10 is fixed to the middle of the upper end of the guide groove 3, and its telescopic end extends into the guide groove 3 and is fixedly connected to the middle of the two support rods 5. When the lifting cylinder 10 extends, it pushes the middle part of the two support rods 5. Because the support rods 5 are constrained by the guide rods 9, they slide upwards along the guide groove 3, thereby driving the lifting tray 4 fixed to the top of the support rods 5 to move upwards. Conversely, when the lifting cylinder 10 retracts, the support rods 5 slide downwards, and the lifting tray 4 lowers accordingly.

[0025] The driven roller 6, which is rotatably connected to the inner side of the lifting tray 4, rotates freely when the workpiece contacts it, so that the workpiece can roll on the lifting tray 4 to reduce friction. The baffle 7 is fixed to one side of the lifting tray 4 to limit the position of the workpiece. The detector 8 in the middle can detect whether the workpiece has reached the predetermined position. When the detector 8 senses the workpiece, it can trigger the lifting cylinder 10 to act or the ejection cylinder 11 to work. The ejection cylinder 11 is fixed to the outside of the mounting frame 2 and aligned with the end of the transport component. When the workpiece is lifted or lowered to the target level, the ejection cylinder 11 extends and pushes the workpiece from the lifting tray 4 to the adjacent transport component to complete the horizontal transfer.

[0026] Example 2: Based on Example 1, please refer to... Figure 5 and Figure 6 The following structure was also disclosed: like Figure 5 As shown, the transport assembly includes a mounting frame 12 fixedly connected to the top of the support beam 1. Forming rollers 13 are rotatably connected to the four corners of the inner side of the mounting frame 12. A transport belt 15 is sleeved on the outer side of the four forming rollers 13. The plane at the top of the transport belt 15 is aligned with the plane at the top of the driven roller 6. Support rollers 14 are rotatably connected to the inner side of the mounting frame 12 at equal intervals. The support rollers 14 are in contact with the top inner side of the transport belt 15.

[0027] like Figure 5 and Figure 6 As shown, three sets of drive components are provided inside the mounting frame 12. Each set of drive components consists of three equally spaced drive rollers 16. Both ends of the drive rollers 16 are fixedly connected to synchronous gears 17. The synchronous gears 17 installed at both ends of adjacent drive rollers 16 mesh with each other. The conveyor belt 15 passes through the three drive rollers 16 to form a Z-shaped structure.

[0028] like Figure 6 As shown, the synchronizing gear 17 extends through the inner side of the mounting frame 12 to both sides of the mounting frame 12. The synchronizing rod 19 is rotatably connected inside the mounting frame 12 via a bearing seat. One end of the synchronizing gear 17, which is located in the middle of the drive assembly, is fixedly connected to the driven bevel gear 18. The outer side of the synchronizing rod 19 is fixedly connected to the equidistantly distributed synchronizing bevel gears 20. The synchronizing bevel gears 20 mesh with the driven bevel gears 18. The side of the synchronizing bevel gears 20 away from the driven bevel gears 18 meshes with the power bevel gear 21, which is driven by a geared motor.

[0029] The transport assembly includes a mounting frame 12 fixed to the top of the support beam 1. The forming rollers 13 at the four corners of the inner side of the mounting frame 12 are used to support and guide the transport belt 15. The equidistant support rollers 14 are in contact with the inner top of the transport belt 15 to prevent the transport belt 15 from sagging and keep it flat. Each drive assembly includes three equidistant drive rollers 16. The synchronous gears 17 at both ends of the drive rollers 16 mesh with each other, so that the three drive rollers 16 in the same group rotate synchronously. The transport belt 15 passes between the three drive rollers 16 to form a Z-shaped structure to increase the friction contact area and improve the drive efficiency.

[0030] Synchronous gear 17 extends into the interior of both sides of mounting frame 12 and is linked with synchronous bevel gear 20 on synchronous rod 19; one end of synchronous gear 17 of the intermediate drive roller 16 of the drive assembly is fixedly connected to driven bevel gear 18, and synchronous rod 19 is rotatably connected to the interior of mounting frame 12 through bearing seat, with synchronous bevel gear 20 fixed on its outer side, and synchronous bevel gear 20 meshing with driven bevel gear 18; when the geared motor drives power bevel gear 21 to rotate, power bevel gear 21 meshes with synchronous bevel gear 20, driving synchronous rod 19 to rotate, and then driving driven bevel gear 18 to rotate through synchronous bevel gear 20, so that drive roller 16 rotates. Due to the meshing relationship of synchronous gear 17, all drive rollers 16 move synchronously, pulling conveyor belt 15 to run in a cycle.
