[0042] Example one:

[0043] Please refer to Figures 1-10 The embodiment is a kind of packing equipment 100, a kind of packing equipment 100 includes and is arranged side by side several feeding units 1, the front end of each feeding unit 1 is provided with carrying unit 2, each feeding unit 1 with each carrying unit 2 between being provided with second banding unit 4, the front end of several carrying units 2 is left and right movably provided with alignment conveying unit 3, the discharge side of alignment conveying unit 3 is provided with first banding unit 6, alignment conveying unit 3 is driven by drive unit 5 It can be moved left and right to sequentially receive the material on several carrying units 2, then alignment conveying unit 3 is conveyed to first banding unit 6 on the material received and carries out second banding operation.

[0044] The feeding unit 1 comprises a feeding trolley 11, the photovoltaic modules are vertically stacked and the whole stack is obliquely arranged on one side of the feeding trolley 11, and the height of the photovoltaic modules is higher than the height of the feeding trolley, so that the second banding unit 4 can perform the banding operation on the outer periphery of the upper end of the photovoltaic modules. The conveying unit 2 comprises a lifting mechanism 21 and a two-way telescopic fork 22 driven by the lifting mechanism 21 to perform lifting movement. The correcting conveying unit 3 comprises a first conveying line 31 and a correcting mechanism 32 arranged above the first conveying line 31 and capable of correcting the photovoltaic modules in the inclined state to the vertical state, the correcting mechanism 32 can correct the material from the A attitude on the feeding trolley 11 to the B attitude, that is, the A attitude of the material on the feeding trolley 11 is vertically stacked and the whole stack is obliquely arranged on one side of the feeding trolley 11, and the B attitude of the material after being corrected by the correcting mechanism 32 is in the vertical state and the whole stack is vertically stacked. In the embodiment, the material is a photovoltaic module, and in other embodiments, it can be a plate-shaped material similar to the photovoltaic module, and the shape and structure of the material are not limited herein.

[0045] The photovoltaic modules are vertically stacked on the pallet, and the pallet and the photovoltaic modules are placed on the feeding trolley 11 together, so that the pallet and the photovoltaic modules are both obliquely arranged on one side of the feeding trolley 11. The feeding trolley 11 comprises a bearing table 111 in an inclined state and a fence 112 arranged on both sides of the bearing table 111, a first limiting plate 114 is arranged on the side of the bearing table 111 in a low position, and a plurality of second limiting plates 113 for the photovoltaic modules to abut against are arranged on the upper end of the fence 112 above the first limiting plate 114. The first limiting plate 114 limits the bottom of the pallet and the photovoltaic modules, and the second limiting plate 113 limits the upper end of the photovoltaic modules, which can prevent the photovoltaic modules from sliding out from the side of the bearing table 111 in a low position.

[0046] Since the photovoltaic modules are obliquely stacked on the feeding trolley 11, the second banding unit 4 also needs to be correspondingly arranged obliquely when performing the banding, and the inclination angle between the second banding unit 4 and the material bearing surface is consistent, the inclination angle between the second banding unit 4 and the horizontal plane is also θ, and the range of the inclination angle θ is consistent with the above, 0 < θ ≤ 3.9°, on the one hand, the inclination angle between the second banding unit 4 and the material bearing surface is consistent, which can ensure that the banding is completely perpendicular to the photovoltaic modules to ensure the accuracy and stability of the banding; on the other hand, 0 < θ ≤ 3.9°, the inclination angle is small, which can ensure the stability and service life of the second banding unit 4, thereby improving the accuracy of the banding. Preferably, the inclination angle θ is 2°-3°, which is the best.

[0047] Specifically, the second strapping unit 4 comprises a second gantry 41, a second strapping mechanism 42 movably arranged on the second gantry 41 and cantilevered, and a second lifting driving module 43 arranged on the second gantry 41 and driving the second strapping mechanism 42 to move up and down, and the second gantry 41 and the second strapping mechanism 42 are both arranged obliquely. The second strapping mechanism 42 is in the shape of a "mouth" and has a material belt guide bin on each side, which can simultaneously perform strapping operations on the four sides of the photovoltaic module. The material belt of the "mouth" shape is wrapped around the outer periphery of the upper end of the photovoltaic module, firmly binding the photovoltaic module, and avoiding the problem of position deviation or falling of the bidirectional telescopic material fork 22 when transporting the photovoltaic module. The second strapping mechanism 42 is a prior art, which can be designed according to the prior art, and is not limited here.

[0056] Embodiment two:

[0057] In the embodiment, the multi-station feeding device can improve the feeding efficiency and meet the requirement of high production rate, and when the production rate is low, the single-station feeding device can be used, and the single-station feeding device is provided in the embodiment two, like Figure 11As shown, a feeding unit 1, a second strapping unit 4, a carrying unit 2, a straightening conveying unit 3 and a first strapping unit 6 are arranged, and the feeding unit 1, the second strapping unit 4, the carrying unit 2 and the straightening conveying unit 3 are arranged in sequence to form a single-station feeding device. The structures of the feeding unit 1, the second strapping unit 4, the carrying unit 2, the straightening conveying unit 3 and the first strapping unit 6 are consistent with those of Embodiment One, and will not be described here again. The feeding trolley 11 is manually pushed into the feeding space 13. When the first sensor 14 detects that the photovoltaic module is placed in the feeding space 13, the second strapping unit 4 performs the strapping operation on the photovoltaic module. The "mouth"-shaped strapping sleeve is sleeved on the upper end of the photovoltaic module to firmly bundle the photovoltaic module. The bidirectional telescopic fork 22 is first extended to one side of the feeding trolley 11 to lift the pallet and the photovoltaic module on the pallet, and then is retracted to the middle position opposite the first lifting module 211 and the second lifting module 212. When the second sensor 216 detects that the bidirectional telescopic fork 22 is placed with the material, the first lifting module 211 and the second lifting module 212 drive the lifting frame 213 to make the photovoltaic module be at the set height, and then extend to one side of the first conveying line 31 to place the pallet and the photovoltaic module on the pallet on the first conveying line 31.

The multiple layers of straightening components 321 act at the same time. The lowermost straightening mechanism 32 performs the straightening action on the pallet, and the multiple layers of straightening mechanisms 32 above simultaneously perform the straightening action on the photovoltaic module to straighten the photovoltaic module into a vertical state. Then the straightened photovoltaic module and the pallet are conveyed to the second conveying line 61. The push cylinder 63 can drive the push plate 64 to straighten the material on the second conveying line 61. Then the first lifting drive module 65 drives the first walking belt mechanism 62 to descend to perform the strapping operation on the bottom of the photovoltaic module.
