[0002] Photovoltaic brackets are supporting components for photovoltaic power generation, and their usage is increasing. The frames of existing photovoltaic brackets are mainly made of C or U-shaped steel. The existing production process of C or U-shaped steel for photovoltaic brackets generally purchases unprocessed coiled steel raw materials from suppliers, and then performs a series of processing processes such as uncoiling, forming, punching, cutting and stacking.

[0003] The existing steel stacking equipment usually has the following problems: (1) When the steel delivered from the previous process is marked steel scrap, it is usually removed from the conveyor line manually, which is not only time-consuming and labor-intensive, but also unsafe. (2) The flipping assembly of the existing stacking equipment is usually driven by a telescopic cylinder (cylinder) to rotate the flip plate, so that the steel follows the flip plate to rotate and flip: on the one hand, the flip plate, as a supporting platform, provides support during the flipping process of the steel. During the flipping process, the steel is not clamped, so the steel is prone to displacement (position offset or front and back tilt) during or after the flipping process, which is not convenient for the robot to pick up the parts, affecting the stacking efficiency; on the other hand, the flip plate is driven by a cylinder, and the performance of the cylinder in terms of control accuracy, response speed, stability and reliability is slightly inferior, which will also affect the stacking efficiency. (3) The walking mechanism and lifting mechanism on the stacking device of the existing stacking equipment usually adopt linear guides or chain drives to achieve walking or lifting, and the positioning accuracy and stability are not high enough.

The second turning rod assembly 16-1 and the third turning rod assembly 16-2 have the same structure, both of which include a turning rod seat 161, a material blocking rod 162 and a second turning rod cylinder 163; the turning rod seat 161 of the second turning rod assembly 16-1 is slidably disposed on the lifting plate 13, the turning rod seat 161 of the third turning rod assembly 16-2 is slidably disposed on the slide rail of the unloading bracket 11, the material blocking rod 162 is hinged on the turning rod seat 161, the cylinder seat of the second turning rod cylinder 163 is connected to the turning rod seat 161, and the piston rod is connected to the material blocking rod 162, and the second turning rod cylinder 163 can drive the material blocking rod 162 to stand up or turn down. Figure 7 As shown, on the unloading trolley 12, push plates 19 are respectively extended toward the two third tipping rod assemblies 16-2, and the push plates 19 serve as mechanical limiters and play a limiting role. During palletizing, the unloading trolley 12 moves horizontally to the stacking position, and the lifting plate 13 rises to a position higher than the unloading trolley 12. The flip rod 152 of the first tipping rod assembly 15, the second tipping rod assembly 16-1, and the material blocking rod 162 of the third tipping rod assembly 16-2 stand up, and the stacking device 200 starts to stack the steel. After a bundle of materials is stacked, the clamping cylinder 18 drives the third tipping rod assembly 16-2 to move and clamp the material pile, and the lifting plate 13 drops to a position lower than the unloading trolley 12. The material pile is placed on the unloading trolley 12, and the material blocking rod 162 of the second tipping rod assembly 16-1 on the lifting plate 13 flips down, and the lateral movement cylinder 20 drives the unloading trolley 12 and the third tipping rod assembly 16-2 to move the material pile from the stacking position. The stacking position is sent to the packaging area. After the material pile is moved out of the stacking position, the lifting plate 13 rises again, and the blocking rod 162 of the second tilting rod assembly 16-1 on the lifting plate 13 stands up again, and the stacking device 200 continues to stack the material. When the unloading trolley 12 moves the material pile horizontally to the packaging area, the third tilting rod assembly 16-2 that moves horizontally with the unloading trolley 12 flips down its blocking rod 162, and then the horizontal cylinder 20 moves the unloading trolley 12 and the two third tilting rod assemblies 16-2 back to the stacking position. After returning to the position, the blocking rods 162 of the two third tilting rod assemblies 16-2 stand up, and prepare for the delivery of the next bundle of material pile according to the above steps, and so on and so forth until the stacking work of all profiles is completed. While the unloading device 300 moves a bundle of material pile in the packaging area, the stacking work of the next bundle of material pile is also carried out at the same time, which saves the waiting time between feeding and stacking and improves the stacking efficiency.
