Description

Technical Field

[0001] This utility model relates to the field of photovoltaic modules, and in particular to a busbar stack welding device. Background Technology

[0002] Photovoltaic modules can save costs by reducing the thickness of the busbar without affecting conversion efficiency. However, the busbar in the area where it is electrically connected to the junction box is prone to overheating due to excessive current. Therefore, the busbar in the above area is thickened. The common method is to weld two busbars of different lengths together.

[0003] In the existing technology, the typesetting equipment is equipped with a carrier tape stage. The tape is first made twice by the tape making mechanism, and the tape transporter also transports the two busbars twice to stack them on the carrier tape stage. Then, the two busbars are welded together by the welding mechanism to form a whole. During this process, the tape transporter cannot transport the next set of busbars to the carrier tape stage, and the tape making mechanism also needs to pause tape making, which affects the welding efficiency of photovoltaic modules.

[0030] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0031] It should be noted that when a component is said to be "set on" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] like Figures 1 to 10 As shown, this application discloses a busbar stack welding device, which includes a base 110, a rotary drive 200, a first belt carrier mechanism, a second belt carrier mechanism, a third belt carrier mechanism 400, a first lifting drive 500, a heating element 600, and a translation drive 120. The first belt carrier mechanism, the second belt carrier mechanism, and the third belt carrier mechanism 400 are all used to support the busbar. The heating element 600 can be a magnetic core welding component, a heating rod, etc., and this application does not impose any restrictions on its use. The rotary drive 200 can be a servo motor, a rotary cylinder, a rotary hydraulic cylinder, etc., and this application does not impose any restrictions on its use. The translation drive 120 can be an electric cylinder, a servo motor, and a rack or lead screw combination, etc., and this application does not impose any restrictions on its use.

[0034] Specifically, the translation drive 120 is disposed on the base 110, and the first carrier belt mechanism and the second carrier belt mechanism are disposed opposite to each other on the drive end of the rotary drive 200. The first and second carrier belt mechanisms can be symmetrically disposed opposite to each other on the drive end of the rotary drive 200, or they can be asymmetrically disposed opposite to each other on the drive end of the rotary drive 200; this application does not impose any limitations on this. When the first lifting drive 500 is disposed on the base 110, the rotary drive 200 is disposed on the drive end of the first lifting drive 500, and the third carrier belt mechanism 400 and the heating element 600 are disposed adjacent to each other on the drive end of the translation drive 120; when the first lifting drive 500 is disposed on the drive end of the translation drive 120, the rotary drive 200 is disposed on the base 110, and the third carrier belt mechanism 400 and the heating element 600 are disposed adjacent to each other on the drive end of the first lifting drive 500.

[0035] With the first lifting drive 500 mounted on the drive end of the translation drive 120, and one of the first and second carrier belt mechanisms carrying the stacked first and second busbars while the other is unloaded, the rotation drive 200 drives the first and second carrier belt mechanisms to rotate, causing either the first or second carrier belt mechanism carrying the first and second busbars to face downwards. The translation drive 120 first drives the first lifting drive 500 to move, and the heating element 600 moves accordingly to be opposite the assembly of the first and second busbars. The first lifting drive 500 then drives the third carrier belt mechanism 400 and the heating element 600. The heating element 600 moves and contacts the combination of the first and second busbars, heating the first and second busbars to form an integrated structure. Then, the first lifting drive 500 drives the heating element 600 away, and the first lifting drive 500 moves the translation drive 120. The third carrier mechanism 400 moves to be opposite the combination of the first and second busbars. The first lifting drive 500 drives the third carrier mechanism 400 to move closer to the combination of the first and second busbars and complete the receiving. At the same time, the other one, which is in an unloaded state, can carry the transporter to transport the next set of the first and second busbars.

[0036] With the first lifting drive 500 mounted on the base 110, and one of the first and second carrier belt mechanisms carrying the stacked first and second busbars while the other is unloaded, the rotation drive 200 drives the first and second carrier belt mechanisms to rotate, causing either the first or second carrier belt mechanism carrying the first and second busbars to face downwards. The translation drive 120 then drives the heating element 600 to move relative to the assembly of the first and second busbars. The first lifting drive 500 then drives the rotation drive 200 to descend, causing the first and second carrier belt mechanisms to move accordingly, and the heating element... 600, the heating element 600 heats the first and second busbars to form an integrated structure. Then, the first lifting drive 500 drives the first and second carrier mechanisms away from the heating element 600. The translation drive 120 drives the third carrier mechanism 400 to move relative to the combination of the first and second busbars. The first lifting drive 500 drives the first and second carrier mechanisms to move closer to the third carrier mechanism 400, so that the third carrier mechanism 400 can receive the combination of the first and second busbars. At the same time, the other one, which is in an unloaded state, can carry the carrier to move the next set of the first and second busbars.

[0037] The above structure utilizes a first and a second belt carrier mechanism, which are positioned opposite each other on the drive end of the rotary drive 200. One of these mechanisms carries the stacked first and second busbars and heats them to form an integrated structure. While the other mechanism, which is in an unloaded state, can carry the next set of first and second busbars, the structure avoids the stagnation of the belt carrier and belt-making mechanism in related technologies, ensuring the rhythm of their operation and thus guaranteeing the welding efficiency of the photovoltaic modules.

[0038] Of course, the first lifting drive component 500 can be a telescopic cylinder, electric cylinder, servo motor and rack or lead screw combination, etc., and this application does not impose any restrictions on it.

[0039] To prevent the stacked first and second busbars from falling off during rotation, either the first or second busbar carrier mechanism can be bonded together before loading. Alternatively, either the first or second busbar carrier mechanism can be equipped with a clamping assembly that clamps the first and second busbars on both sides along their length. In another alternative, either the first or second busbar carrier mechanism can include a pressing member 310, a second lifting drive member 320, and a first busbar carrier platform 330. Specifically, the first busbar carrier platform 330 is used to carry the stacked first and second busbars. The first busbar carrier platform 330 is located on the drive end of the rotary drive member 200, and the second lifting drive member 320 is located on the first busbar carrier platform 330. One end of the pressing member 310 is hinged to the drive end of the second lifting drive member 320, and the middle part of the pressing member 310 is hinged to the first busbar carrier platform 330.

[0040] When the first carrier platform 330 carries the first busbar, the rotary drive 200 drives the first carrier platform 330 to rotate so that it is opposite to the third carrier mechanism 400. The second lifting drive 320 drives the pressing member 310 to rotate around the first carrier platform 330 and press the stacked first busbar and second busbar, thereby preventing at least one of the stacked first busbar and second busbar from falling or becoming skewed. Of course, when the third carrier mechanism 400 receives the combination of the first busbar and the second busbar, the second lifting drive 320 drives the pressing member 310 to rotate around the first carrier platform 330 and move away from the first busbar and the second busbar.

[0041] Of course, the second lifting drive component 320 can be a telescopic cylinder, electric cylinder, servo motor and rack or lead screw combination, etc., and this application does not impose any restrictions on it.

[0042] In a further technical solution, either the first carrier belt mechanism or the second carrier belt mechanism may further include a third lifting drive 340 and a cooling pressure needle 360. Specifically, the third lifting drive 340 is disposed on the driving end of the rotary drive 200, and the cooling pressure needle 360 ​​is disposed on the driving end of the third lifting drive 340. The pressing end of the cooling pressure needle 360 ​​extends into the first through hole of the first carrier belt stage 330.

[0043] When the first carrier platform 330 carries the first busbar, the rotary drive 200 drives the first carrier platform 330 to rotate to be opposite the third carrier mechanism 400. The first lifting drive 500 can drive the third carrier mechanism 400 to move closer, so that the first busbar and the second busbar come into contact and overlap. The heating element 600 heats the first busbar and the second busbar. The third lifting drive 340 drives the cooling pressure needle 360 ​​to move and press the first busbar and the second busbar onto the heating element 600 so that they are in full contact. After the heating element 600 heats the first busbar and the second busbar, the cooling pressure needle 360 ​​can release cooling gas to cool the first busbar and the second busbar.

[0044] Of course, the third lifting drive component 340 can be a telescopic cylinder, electric cylinder, servo motor and rack or lead screw combination, etc., and this application does not impose any restrictions on it.

[0045] In a further technical solution, either the first carrier belt mechanism or the second carrier belt mechanism may further include an adsorption member 350. Specifically, the adsorption member 350 is disposed on the driving end of the rotary drive member 200, and the adsorption end of the adsorption member 350 extends into the second through hole of the first carrier belt stage 330, and the end face of the adsorption end is flush with the bearing surface of the first carrier belt stage 330. The first through hole and the second through hole are spaced apart. When the first carrier belt stage 330 carries the first busbar, the adsorption member 350 adsorbs the first busbar and cooperates with the pressing member 310 to fix the first busbar.

[0046] In this embodiment, multiple bearing protrusions can be arrayed on the bearing end face of the first carrier stage 330. The multiple bearing protrusions can form line contact or small area surface contact with the busbar, thereby avoiding excessive adhesion between the combination of the first busbar and the second busbar and the first carrier stage 330 after the heating element 600 is heated.

[0047] In this embodiment of the application, the third carrier mechanism 400 may include a second carrier stage 410 and a lifting component 420. Specifically, the lifting component 420 is disposed on the second carrier stage 410, and the second carrier stage 410 is disposed on the driving end of the translation drive member 120 or the driving end of the first lifting drive member 500.

[0048] When the first lifting drive 500 drives the third carrier mechanism 400 to move closer to and receive the combination of the first busbar and the second busbar, the end face of the drive end of the lifting component 420 is raised and moved to be flush with the end face of the bearing end of the second carrier table 410, so that the combination of the first busbar and the second busbar can be fully received.

[0049] In a further technical solution, the lifting assembly 420 may include a telescopic drive member 421 and a receiving plate 422. Specifically, the telescopic drive member 421 is disposed on the second carrier platform 410, and the receiving plate 422 is disposed on the drive end of the telescopic drive member 421. The telescopic drive member 421 can drive the receiving plate 422 to rise and fall, which can not only support the combination of the first and second busbars, but also avoid interference with the rotation of the pressing member 310.

[0050] In a further technical solution, the third carrier mechanism 400 may also include a bending component 430, which is disposed on the receiving plate 422. The bending component 430 is used to bend the combination of the first busbar and the second busbar when the third carrier mechanism 400 receives it, so as to meet the requirements for subsequent electrical connection with the junction box.

[0051] In another technical solution, the bending assembly 430 may include a pressure belt drive 431, a bending block 432 and a fourth lifting drive 433. Specifically, the fourth lifting drive 433 and the pressure belt drive 431 are disposed on the receiving plate 422, and the bending block 432 is disposed on the driving end of the fourth lifting drive 433.

[0052] When the combination of the first and second busbars is received by the third carrier mechanism 400, the telescopic drive 421 first drives the receiving plate 422 to move, so that the receiving surface of the receiving plate 422 is flush with the end face of the bearing end of the second carrier platform 410. Then the pressing drive 431 presses the combination of the first and second busbars. Finally, the fourth lifting drive 433 drives the bending block 432 to lift and contact the combination, and bend it.

[0053] Of course, the fourth lifting drive component 433 can be a telescopic cylinder, electric cylinder, servo motor and rack or lead screw combination, etc., and this application does not impose any restrictions on it.

[0054] Alternatively, the pressure belt drive 431 can be a rotary cylinder, with its drive end having two degrees of freedom: rotation and lifting, capable of pressing or moving away from the assembly; or, the pressure belt drive 431 can include a telescopic cylinder and a pressure block disposed at the drive end of the telescopic cylinder, the telescopic cylinder driving the pressure block to press or move away from the assembly. This application does not impose any limitations on this.

[0055] Of course, there can be multiple pressure belt drivers 431, and multiple pressure belt drivers 431 can be respectively set on both sides of the bending block 432.

[0056] In this embodiment, the heating element 600 may include a mounting base 610, an electromagnetic core 620, and a heat sink 630. Specifically, the mounting base 610 is disposed on the driving end of the translation drive 120 or the driving end of the first lifting drive 500. The mounting base has a non-communicating mounting groove A and a heat sink B. The electromagnetic core 620 is disposed in the mounting groove A. The heat sink 630 is covered on the heat sink B. The heat sink 630 has a plurality of arrayed heat dissipation protrusions. The heat dissipation protrusions can increase the contact area between the heat sink 630 and the air, thereby improving the heat dissipation efficiency.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
