[0001] This utility model relates to the field of automated assembly technology of photovoltaic modules, and in particular to a welding strip placement fixture and welding strip making mechanism. Background Technology

[0002] Solar energy, as a renewable energy source, is abundant, can be used for free, requires no transportation, and causes no pollution to the environment. It creates a new way of life for mankind and ushers society and humanity into an era of energy conservation and pollution reduction.

[0003] Solar cells are the core component of a solar power generation system and also the most valuable part of the system.

[0004] In the existing battery cell assembly process, adhesive tape is usually used to bond the welding strip and the battery cell. If the welding strip and the film strip do not make close contact during the bonding process, a complex handling hand is required to move the welding strip and the film strip at the same time, which will affect the subsequent bonding.

[0005] Therefore, there is an urgent need for a welding strip placement fixture and welding strip making mechanism that can ensure a tight connection between the film strip and the welding strip, simplify the structure of the handling hand, and improve the bonding efficiency. Utility Model Content

[0006] The purpose of this invention is to solve the problem of poor contact between the welding strip and the film strip, and to provide a welding strip placement fixture and welding strip making mechanism, which can ensure a tight connection between the film strip and the welding strip, simplify the structure of the handling hand, and improve the bonding efficiency.

[0007] To solve the above-mentioned technical problems, as one aspect of this utility model, a welding strip placement fixture is provided, including: a placement platform, grippers and a film strip connecting device;

[0008] The placement platform is used to place the welding strip assembly;

[0009] The grippers are located at the ends of the welding strip and are used to hold the welding strip assembly.

[0010] The membrane strip connecting device is located below the welding strip assembly and is used to reinforce the connection between the membrane strip and the welding strip.

[0011] According to an example embodiment of the present invention, there are two grippers, which are respectively disposed at both ends of the welding strip.

[0012] According to an exemplary embodiment of the present invention, the welding strip placement fixture further includes a first cutting blade, which is disposed between two grippers and is perpendicular to the length direction of the welding strip.

[0013] According to an exemplary embodiment of the present invention, the first cutting blade is disposed in the middle of the two grippers.

[0014] According to an exemplary embodiment of the present invention, there are multiple membrane tape connecting devices, of which at least two are disposed near the end of the welding tape.

[0015] According to an exemplary embodiment of the present invention, the length direction of the membrane tape connecting device is perpendicular to the length direction of the welding strip.

[0016] According to an exemplary embodiment of the present invention, the membrane tape connecting device includes a heating device and a cooling device.

[0017] According to an exemplary embodiment of the present invention, the heating device is an electromagnetic induction heating device.

[0018] According to an example embodiment of the present invention, the heating temperature of the heating device is 70-100 degrees Celsius.

[0019] As a second aspect of this utility model, a welding strip making mechanism is provided, including multiple welding strip placement fixtures, multiple second cutting blades, a strip puller, and a welding strip roll;

[0020] The welding strip coils are used to supply welding strip sets;

[0021] Multiple welding strip placement fixtures are set up side by side, and a second cutting blade is set between every two welding strip placement fixtures;

[0022] The pull handle is located on one side of the welding strip placement fixture and is used to lay the welding strip in the welding strip roll onto the placement platform of the welding strip placement fixture.

[0023] The beneficial effects of this utility model are:

[0024] This invention heats the welding strip, and after the membrane strip is adsorbed, it moves the membrane strip above the welding strip and then lowers it, so that the welding strip and the membrane strip come into contact. The heat of the welding strip itself causes the membrane strip and the welding strip to melt at the contact point. Then the welding strip and the membrane strip are cooled, and the welding strip and the membrane strip adhere to form a whole. The membrane strip transporter only needs to adsorb to move the membrane strip and the welding strip at the same time, which simplifies the structure of the membrane strip transporter and facilitates the maintenance of the membrane strip transporter.

[0031] The following example describes the welding strip placement fixture and welding strip making mechanism of this utility model. This example is only a part of the embodiments of this utility model, but the protection scope of this utility model is not limited thereto. All other embodiments obtained by those skilled in the art without creative effort should be covered within the protection scope of this utility model.

[0032] As the first embodiment of this utility model, a welding strip making mechanism is provided, such as... Figure 1 As shown, it includes a welding strip placement fixture 1, multiple second cutting blades 3, and a strap pulling handle ( Figure 1 (not shown in the image), solder strip rolls ( Figure 1 (Not shown in the image).

[0033] The welding strip roll is used to supply welding strip sets. The strip puller is located on one side of the welding strip placement fixture 1 and is used to lay the welding strip in the welding strip roll onto the placement platform 11 of the welding strip placement fixture 1.

[0034] Multiple welding strip placement fixtures 1 are arranged side by side, and a second cutting blade 3 is placed between every two welding strip placement fixtures 1. The second cutting blade 3 is used to cut the welding strip group.

[0035] like Figure 2As shown, the welding strip placement fixture 1 includes: a placement platform 11, a gripper 12, a film strip connecting device 13, and a first cutting blade 14.

[0036] The placement platform 11 is used to place the welding strip assembly.

[0037] The gripper 12 is located at the end of the welding strip 2 and is used to hold the welding strip assembly. There are two grippers 12, which are respectively located at both ends of the welding strip 2. The gripper 12 can extend and retract vertically. After the puller places the welding strip assembly on the placement platform 11, the gripper 12 extends upward and holds the welding strip assembly to prevent the welding strip assembly from moving during cutting.

[0038] A first cutting blade 14 is disposed between two grippers 12, and the first cutting blade 14 is perpendicular to the length direction of the solder strip 2. In a preferred embodiment, the first cutting blade 14 is disposed exactly in the middle of the two grippers 12. The first cutting blade 14 is used to cut the solder strip group, dividing the solder strip group into two equal groups.

[0039] The membrane strip connecting device 13 is positioned below the welding strip assembly to reinforce the connection between the membrane strip and the welding strip 2. Multiple membrane strip connecting devices 13 are present, with at least two positioned near the end of the welding strip 2, enabling better reinforcement of the membrane strip and welding strip 2. Figure 1 As shown, the film strip connecting device 13 is elongated, with its length direction perpendicular to the length direction of the solder strip 2, to reinforce each solder strip in the entire solder strip assembly. The film strip connecting device 13 includes a heating device and a cooling device. Its principle is as follows: the heating device heats the solder strip 2, causing the film strip bonded to the solder strip 2 to melt; the cooling device cools the melted film strip that forms a whole with the solder strip 2, improving the stability of the connection between the film strip and the solder strip 2. The heating device is an electromagnetic induction heating device. The heating temperature of the heating device is 70-100 degrees Celsius. The solder strip 2 is made of tin-coated copper, which has high thermal conductivity; when multiple points are heated, it is equivalent to heating the entire solder strip 2. By heating the solder strip, after the film strip has absorbed the heat, the film strip is moved above the solder strip 2 and then lowered, causing the solder strip 2 to contact the film strip. Through the heat of the solder strip 2 itself, the contact point between the film strip and the solder strip 2 melts. Then, the solder strip 2 and the film strip are cooled, and the solder strip 2 and the film strip adhere to form a whole.

[0040] like Figure 3 As shown, the membrane strip transporter includes a membrane strip adsorption plate 41 and a telescopic structure 42. The membrane strip adsorption plate 41 is fixed below the telescopic structure 42 and is used to adsorb membrane strips or adsorb membrane strips that are bonded together as a whole. After the welding strip placement fixture 1 of this solution is adopted, the membrane strip transporter 4 only needs to adsorb to transport the membrane strip and welding strip 2 at the same time, so as to achieve the effect of transporting the membrane strip and welding strip 2 at the same time, simplifying the structure of the membrane strip transporter 4 and facilitating the maintenance of the membrane strip transporter 4.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
