In order to enable those in the art to better understand the solution of the present application, the technical solutions in the specific embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Figures 1 and 2 show a preparation equipment 100 for photovoltaic cells 200. The preparation equipment 100 is used to connect the photovoltaic cells 200 and the conductive connector 300. The preparation equipment 100 includes an equipment body 11 , a first mechanism 12 and a second mechanism 13 . The first mechanism 12 is at least partially disposed on the device body 11. The first mechanism 12 is used for loading the photovoltaic cell sheets 200, loading the adhesive parts 400, heating the photovoltaic cell sheets 200 and the conductive connectors 300, and the conductive connectors 300. and heating of the adhesive member 400, cutting of the conductive connecting member 300, and lowering of the photovoltaic cell sheet 200. The second mechanism 13 is used to carry the photovoltaic cell sheet 200, the conductive connector 300 and the adhesive member 400, connect the photovoltaic cell sheet 200 to the conductive connector 300, connect the conductive connector 300 to the adhesive member 400, and pass through the first mechanism 12 Complete the loading of the photovoltaic cell sheets 200, the loading of the adhesive parts 400, the heating of the photovoltaic cells 200 and the conductive connectors 300, the heating of the conductive connectors 300 and the adhesive members 400, the cutting of the conductive connectors 300 and the photovoltaic cells in sequence. The next piece of film 200.

As an optional implementation method, the photovoltaic cell sheet 200 can be made of silicon material; the conductive connecting member 300 can be a soldering tape; and the adhesive member 400 can be a hot melt adhesive film or other materials that become sticky after being heated. Specifically, the conductive connecting member 300 may be configured as an aluminum wire welding strip, and the conductive connecting member 300 may be configured as a special-shaped welding strip. Among them, special-shaped welding ribbons include triangular welding ribbons, diamond-shaped welding ribbons, rectangular welding ribbons, etc. It should be noted that the conductive connector 300 can also be configured as a conventional circular soldering strip.

In order to clearly illustrate the technical solution of the present application, the front side, back side, left side, right side, upper side, and lower side as shown in Figure 1 are also defined to represent the front side, back side, left side, and right side of the preparation device 100. Side, upper side, lower side.

As an implementation manner, the first mechanism 12 includes an upper piece assembly 121, a processing assembly 122 and a lower piece assembly (not shown). The upper sheet assembly 121 is used to place the photovoltaic cell sheet 200 and the adhesive member 400 on the second mechanism 13; the processing assembly 122 is used to heat the photovoltaic cell sheet 200 and the conductive connector 300, and heat the conductive connector 300 and the adhesive member 400. Heating is performed, and then the conductive connecting member 300 is cut; the lower piece assembly is used to remove the photovoltaic cell sheet 200 from the second mechanism 13 . Through the above arrangement, the upper sheet area, the processing area and the lower sheet area are formed at corresponding positions of the upper sheet assembly 121, the processing assembly 122 and the lower sheet assembly. In one embodiment, the upper sheet assembly 121 , the processing assembly 122 and the lower sheet assembly are all located above the second mechanism 13 , thereby facilitating the execution of corresponding operations on the second mechanism 13 . It can be understood that the arrangement of the upper sheet component 121, the processing component 122 and the lower sheet component can be adjusted according to changes in the connection process of the photovoltaic cell sheet 200 and the conductive connector 300, as long as the upper sheet area and the processing area are formed at different positions. And the next area is enough.

As shown in Figures 2 and 3, specifically, the second mechanism 13 includes at least one carrier body 131. The carrier body 131 is used to carry the photovoltaic cell sheet 200, the conductive connecting member 300 and the adhesive member 400. After the connecting member 300 and the adhesive member 400 are placed on the carrier body 131, the photovoltaic cell sheet 200, the conductive connecting member 300 and the adhesive member 400 can be heated by the processing assembly 122, so that the photovoltaic cell sheet 200 and the conductive connecting member 300 are connected, and the The adhesive part 400 and the conductive connection part 300 are connected. The connection between the photovoltaic cell sheet 200 and the conductive connector 300 may be by welding; the connection between the adhesive member 400 and the conductive connector 300 may be by bonding.

The carrier body 131 has a degree of freedom of movement, so that the carrier body 131 moves between the upper sheet assembly 121, the processing assembly 122 and the lower sheet assembly to form the first, second and third work stations. The freedom of movement of the carrier body 131 means that the carrier body 131 can move along the front-rear direction, the up-down direction, and/or the left-right direction of the preparation device 100. More specifically, the carrier body 131 can at least move along the front-rear direction of the preparation device 100, So that the carrier body 131 can move between the first station, the second station and the third station.

It can be understood that the second mechanism 13 may also include several carrier bodies 131, thereby improving the working efficiency of the preparation equipment 100. At this time, in addition to moving along the front and rear directions of the preparation equipment 100 , the carrier body 131 can also move at least along at least one of the up and down directions and the left and right directions of the preparation equipment 100 , thereby preventing the interference between several carrier bodies 131 . Interference to avoid affecting the normal operation of the preparation equipment 100.

In one embodiment, the upper sheet assembly 121 takes the form of a first robot to place the photovoltaic cell sheet 200 and the adhesive member 400 on the carrier body 131 . Furthermore, an adsorption part is provided at the end of the first robot hand. The adsorption part can adsorb the photovoltaic cell sheet 200 and the adhesive member 400 through vacuum adsorption, thereby driving the photovoltaic cell sheet 200 and the adhesive member 400 to move and place them on the carrier body 131 . The processing component 122 can use a laser to heat the photovoltaic cells 200 and the conductive connectors 300, the conductive connectors 300 and the adhesive components 400; the processing component 122 can use a laser or a high-speed motor and a grinding wheel, and the laser or high-speed motor drives the grinding wheel to conductive connections. The parts 300 are cut to obtain conductive connecting parts 300 that are connected to the photovoltaic cells 200 . The unloading assembly takes the form of a second manipulator to grab and unload the photovoltaic cell sheets 200 that have been heated and connected. Among them, the laser cutting of the processing component 122, the placement of the photovoltaic cells 200 and the sticky parts 400 by the first robot, and the lowering of the photovoltaic cells 200 by the second robot all need to cooperate with the vision system, so that the sticky parts 400 or photovoltaic cells can be placed. The position of the sheet 200 is appropriately adjusted. For example, the arrangement direction and arrangement position of the adhesive member 400 and the photovoltaic cell sheet 200 on the carrier body 131 can be adjusted by the first robot hand.

It can be understood that the structures of the first robot arm and the second robot arm can be configured to be consistent, that is, the upper sheet assembly 121 and the lower sheet assembly can be configured to have the same structure. As an implementation method, the upper sheet assembly 121 and the lower sheet assembly can also be configured as the same component, that is, the first work station and the third work station can overlap. When the photovoltaic cell sheet 200 needs to be unloaded, the carrier body 131 moves from the second station to the first station, and uses the first robot to unload the photovoltaic cells 200, thus simplifying the structure of the preparation equipment 100, improving the structural compactness of the preparation equipment 100, and saving the cost of the preparation equipment 100.

Place it on the second operating surface 1312 and adsorb and fix it to the second operating surface 1312 through the second adsorption hole 1314, and then wind the conductive connector 300 around the photovoltaic cell sheet 200 and the adhesive member 400; when the carrier body 131 is in the second During the work station, the processing component 122 heats the photovoltaic cell sheet 200 and the conductive connector 300, the conductive connector 300 and the adhesive member 400, so that the photovoltaic cell sheet 200 and the conductive connector 300 are connected, and the adhesive member 400 and the conductive connector 300 are connected. To connect, the processing component 122 cuts the conductive connector 300 along the junction of the first operating surface 1311 and the second operating surface 1312 to obtain the conductive connector 300 that is connected to the photovoltaic cell sheet 200; when the carrier body 131 is in the third At the work station, the lowering assembly removes the photovoltaic cell sheets 200 processed by the processing assembly 122 .

In this application, the first operating surface 1311 and the second operating surface 1312 are distributed along the winding direction of the conductive connector 300 . As an optional implementation manner, the areas and shapes of the first operation surface 1311 and the second operation surface 1312 can be set to be consistent.
