[0031] The utility model is further described in detail below in conjunction with specific embodiments.

[0032] Example:

[0033] like Figure 1 As shown, a photovoltaic module EVA small block loading machine 100 of the utility model comprises a conveying unit 1, a detection unit 2, a first loading unit 3a, a second loading unit 3b and a plurality of material trays 4. The conveying unit 1 conveys the photovoltaic module 200 along the X direction, and the first loading unit 3a and the second loading unit 3b are arranged on both sides of the Y direction of the conveying unit 1. The X direction and the Y direction are both located in the horizontal plane and are perpendicular to each other.

[0034] The conveying unit 1 is used to convey the photovoltaic module 200 to the assembly area and to center and position it. The material tray 4 is used to convey the EVA small pieces 300 to the corresponding loading units in batches. The first loading unit 3a and the second loading unit 3b place the EVA small pieces 300 from both sides of the photovoltaic module 200 to the installation area of ​​the photovoltaic module 200 respectively. The EVA small piece 300 is a thin sheet material with a hole in the middle, and the hollow part is passed upward by the lead 201 on the photovoltaic module 200 to complete the placement. The conveying unit 1, the detection unit 2, the first loading unit 3a, and the second loading unit 3b are all modular designs, which are easier to replace parts and debug than the whole machine structure.

[0035] like Figure 2 As shown, the conveying unit 1 includes a synchronous conveyor belt 11 whose conveying direction is along the X direction, a plurality of X-direction alignment mechanisms 12 arranged on both sides of the synchronous conveyor belt 11 in the X direction, a plurality of Y-direction centering mechanisms 13 arranged on both sides of the Y direction of the synchronous conveyor belt 11, and a plurality of auxiliary rollers 14 whose conveying direction is along the X direction are also arranged in the middle of the Y direction of the synchronous conveyor belt 11.

[0036] The synchronous conveyor belt 11 is used to move the photovoltaic module 200. It has two strip-shaped load-bearing positions at a relatively long distance on the bottom of the photovoltaic module 200. The main part of the photovoltaic module 200 is fragile glass, so the auxiliary roller 14 is used to support the middle part of the photovoltaic module 200 to prevent the middle part from being overhanging too much and deforming to cause glass breakage. When the photovoltaic module 200 is located in the middle of the synchronous conveyor belt 11, it is necessary to use the X-direction alignment mechanism 12 and the Y-direction centering mechanism 13 to clamp the sides from all sides, so that the photovoltaic module 200 can maintain its position when the EVA small block 300 is placed.

[0037] like Figure 3 and Figure 6 As shown, the detection unit 2 includes a detection bracket 21 straddling the conveying unit 1 and a plurality of detection components 22 arranged side by side on the detection bracket 21 in the Y direction. The detection bracket 21 includes a crossbeam 211 for adjusting and fixing the position of the detection component 22 in the Y direction. The detection component 22 includes a fixed frame 221 connected to the detection bracket 21, a swing frame 222 adjustably connected to the fixed frame 221 rotatably along the Y axis, and a camera 223 and a light source module 224 arranged on the swing frame 222.

[0038] The light source module 224 provides stable external lighting conditions for the camera 223. Because the EVA block 300 needs to be placed on the lead 201 from top to bottom, the camera 223 always obliquely photographs the photovoltaic module 200. The Y-axis position of the camera 223 is controlled by the relative position of the fixed frame 221 and the beam 211, and the oblique angle is controlled by the angle between the fixed frame 221 and the swing frame 222.

[0039] like Figure 4 As shown, the material tray 4 includes a rectangular bottom plate 41, a pair of handles 411 arranged on both sides of the wide side of the bottom plate 41, a plurality of baffles 42 arranged at intervals on the upper surface of the bottom plate 41, and a plurality of fixing needles 43 located on the side of the baffle 42. The baffle 42 includes blocking portions 421 corresponding one by one to the EVA blocks 300, and each fixing needle 43 is located on one side of a blocking portion 421.

[0040] The handle 411 is used to facilitate the operator to carry the tray 4. The tray 4 allows the EVA small pieces 300 to be positioned in batches on the first loading unit 3a or the second loading unit 3b, thereby facilitating the material removal component to remove the material. The baffle 42 is used to separate the EVA small pieces 300 and allow the EVA small pieces 300 to be inserted on the fixing needle 43 at the same angle.

[0041] like Figure 5 and Figure 6 As shown, the first loading unit 3a and the second loading unit 3b have similar structures, both of which include a base 31, a mechanical arm 32 disposed on the upper part of the base 31, and a material picking assembly disposed at the free end of the mechanical arm 32. The material picking assembly includes a material picking rack 331 connected to the mechanical arm 32, a plurality of elastic suction nozzles 332 disposed in pairs at the lower part of the material picking rack 331, and a sensor 333 for detecting the height of each pair of elastic suction nozzles 332 relative to the material picking rack 331. The upper part of the base 31 has a platform 311 for positioning and placing the material tray 4, and the lower part has double-track wheels 312. In the embodiment, the material picking assembly on the first loading unit 3a is a first material picking assembly 33a, which is provided with two pairs of elastic suction nozzles 332 and two sensors 333, and the material picking assembly on the second loading unit 3b is a second material picking assembly 33b, which is provided with a sensor 333.

[0042] The first loading unit 3a and the second loading unit 3b both use elastic suction nozzles 332 to suck the EVA small pieces 300. The two elastic suction nozzles 332 are adsorbed on both sides of the small holes of the EVA small pieces 300, avoiding the hollow position, and then moved to the lead 201 for placement. The sensor 333 is used to determine whether the elastic suction nozzle 332 has contacted the EVA small pieces 300. Initially, the highest point of the elastic suction nozzle 332 is located below the sensing path of the sensor 333. Because no matter whether the EVA small pieces 300 are located on the material tray 4 or on the photovoltaic assembly 200, they will rise relative to the material taking frame 331 due to the force, and thus be detected by the sensor 333, so it can be determined whether the elastic suction nozzle 332 has completed the action of taking or placing the material. In this embodiment, a total of three EVA small pieces 300 are to be placed, so one of the two loading units has two elastic suction nozzles 332, and the other has one elastic suction nozzle 332. The total number of elastic suction nozzles 332 on the two material taking components is equal to the total number of EVA small pieces 300. Considering the maximization of work efficiency, the workload should be evenly distributed to the two material taking components, so the number of elastic suction nozzles 332 on each side is as close to half of the total number of EVA blocks 300 as possible, and the difference in the number of pairs of elastic suction nozzles 332 on both sides does not exceed 1, that is, they can be the same or one side can have one more pair than the other side. The double-track wheel 312 enables the loading unit 3a to move freely when it is not fixed to the ground, and can more quickly find the relative position with the conveying unit 1.

[0043] The use process of the photovoltaic module EVA small block feeder 100 is as follows:

[0044] The photovoltaic module 200 runs to the synchronous conveyor belt 11 of the equipment through the front-end assembly line, and the X-direction alignment mechanism 12 and the Y-direction centering mechanism 13 align the four sides of the photovoltaic module 200; multiple groups of EVA small blocks 300 are manually placed in the material tray 4, and then placed on the platform 311 of the first loading unit 3a or the second loading unit 3b; driven by the corresponding mechanical arm 32, the first material picking component 33a and the second material picking component 33b each run to the top of the nearest material tray 4, and then rely on a group of two elastic suction nozzles 332 to suck the EVA small blocks 300, and the first material picking component 33a sucks two EVA small blocks 300, The second picking component 33b sucks up a small EVA block 300; the sensor 333 detects that the elastic suction nozzle 332 is in place, and then the first picking component 33a and the second picking component 33b each move the small EVA block 300 to the top of the photovoltaic component 200, and under the detection of the camera 223, the small EVA blocks 300 are placed on the respective leads 201 of the photovoltaic component 200 in turn, so that the small EVA blocks 300 are passed through by the leads 201, and the discharge is completed; the photovoltaic component 200 that has completed the discharge is released by the X-direction straightening mechanism 12 and the Y-direction centering mechanism 13, and the synchronous conveyor belt 11 moves it along the X-direction to the next station outside the equipment.

[0045] The device can automatically place the EVA small block 300 at the lead 201 position of the photovoltaic module 200, thus realizing the automation of the work.

[0046] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
