DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0030] The bus bar of the traditional stacking welding machine intersects with the moving track of the battery string, which causes the stacking welding machine to perform more moving steps, in order to solve the problem, the utility model provides a bus bar multi-line different moving transportation module, which can be used as the welding backing plate 1 of the bus bar and the battery string, and can also move the bus bar to avoid the moving track of the battery string.

[0031] In the present document, the X-axis and the Y-axis are both horizontal directions, the X-axis is perpendicular to the Y-axis, and the Z-axis is a vertical direction.

[0032] Reference Figure 1 The bus bar multi-line different moving transportation module comprises at least one welding backing plate 1 extending along the X-axis in the length direction, and a Y-axis driver 2 driving the welding backing plate 1 to move along the Y-axis direction.

[0033] In the stacking welding machine to which the embodiment belongs, the length direction of the bus bar is arranged along the X-axis, the battery string is moved along the Z-axis by a battery string carrying device, the bus bar is moved along the Y-axis and the Z-axis by a bus bar cross-intersection carrying module, and the bus bar multi-line different moving transportation module drives the bus bar to move along the Y-axis direction.

[0034] In the present embodiment, the stacking welding machine comprises three welding backing plates 1 and three Y-axis drivers 2, so as to transport three groups of bus bars at the two ends and the middle of the solar cell respectively, only two welding backing plates 1 and two Y-axis drivers 2 are shown in the figure, and the remaining one welding backing plate 1 and one Y-axis driver 2 are not shown in the figure.

[0035] The working process of the bus bar multi-line different moving transportation module comprises the following steps.

[0036] Step one, after the bus bar is punched and bent, the bus bar cross-intersection carrying module moves the bus bar to the welding backing plate 1.

[0037] Step two, the Y-axis driver 2 drives the welding backing plate 1 to move to both sides along the Y-axis, so that the welding backing plate 1 carrying the bus bar avoids the directly above of the battery string.

[0038] Step three, the execution part of the battery string carrying device moves downward, adsorbs the battery string, and then drives the battery string to move upward along the Z-axis, so that the battery string moves from the lower side of the welding backing plate 1 to the upper side of the welding backing plate 1.

[0039] Step four, the Y-axis driver 2 drives the welding backing plate 1 to move to the middle along the Y-axis, so that the welding backing plate 1 carrying the bus bar moves to the welding position of the battery string.

[0040] Step five, the battery string carrying device drives the battery string to move downward along the Z-axis, so that the battery string, the bus bar and the welding backing plate 1 are converged, and then the welding machine welds the battery string and the bus bar.

[0041] Preferably, the Y-axis driver 2 adopts a synchronous belt sliding table, which has high precision and speed, and can meet the requirements of driving the welding pad plate 1 to avoid the battery string in time and driving the welding pad plate 1 to accurately reach the welding position.

[0042] Specifically, referring to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 , the specific structure of the welding pad plate 1 includes a cross beam 11, a plurality of pad modules 12 and a plurality of suction cups 3.

[0043] The two ends of the cross beam 11 are respectively connected to the execution parts of the two Y-axis drivers 2, so that the cross beam 11 can move stably.

[0044] The plurality of pad modules 12 are installed on the top of the cross beam 11 along the X-axis at equal intervals, and the pad modules 12 are detachably connected to the cross beam 11, so as to form a stable and easy-to-maintain welding plane above the cross beam 11.

[0045] The suction cups 3 and the vacuum pipe groups connecting each suction cup 3 are installed inside the cross beam 11, the air inlets of the suction cups 3 are arranged above the pad modules 12 through the pad modules 12, and the air inlets of the suction cups 3 are flexible.

[0046] When the busbar is placed on the pad module 12, the air inlets of the suction cups 3 are pressed down to the height of the bottom wall parallel to the pad module 12, the vacuum pump sucks air through the vacuum pipe group, so that the suction cups 3 generate suction force to the bottom wall of the busbar, so that the Y-axis driver 2 can stably transport the busbar when driving the cross beam 11 to move.

[0047] Specifically, referring to Figure 5 , the air outlet of each suction cup 3 is connected to a four-way valve 4, the four-way valve 4 has a first end 41 and a second end 42 arranged vertically, and a third end 43 and a fourth end 44 arranged horizontally, the first end 41 of the four-way valve 4 is connected to each suction cup 3, and the other end of the four-way valve 4 is connected to the vacuum pipe group and the adjacent suction cup 3, so as to balance and stabilize the suction force of each suction cup 3.

[0048] Among them, the vacuum pipe group includes a first vacuum pipe 5 and a second vacuum pipe 6.

[0049] The first vacuum pipe 5 has a relatively thick pipe diameter, and is arranged away from the suction cup 3, the first vacuum pipe 5 has an air inlet corresponding to each suction cup 3 and an air outlet connected to the vacuum pump, the air inlet of the first vacuum pipe 5 is connected to the second end 42 of the four-way valve 4 through a hose (not shown in the figure), and the first vacuum pipe 5 is mainly used to suck air from the suction cup 3 to realize the negative pressure adsorption function of the suction cup 3.

[0050] The second vacuum pipe 6 has a relatively thin pipe diameter, is arranged close to the suction disc 3, is connected to a third end 43 of one four-way pipe 4 and a fourth end 44 of an adjacent other four-way pipe 4, thereby sequentially connecting each four-way pipe 4, and is mainly used for balancing the air pressure difference between adjacent suction discs 3, so that the suction force of each suction disc 3 is substantially the same.

[0051] Further, after the busbar is integrally welded with the battery string and the vacuum pump stops working, there is still a certain suction force between the suction disc 3 and the busbar, and since the battery string is thin and structurally fragile, the battery string cannot be moved upward by the battery string carrying device to drive the busbar to move upward, thereby separating the busbar from the suction disc 3, otherwise the battery string is easily deformed or broken. In order to solve this problem, the backing plate module 12 has the function of lifting the busbar upward when the suction disc 3 is not working.

[0052] Specifically, referring to Figure 3 , Figure 4 and Figure 7 , the top of the backing plate module 12 is embeddedly installed with a top rod 13, the top rod 13 can move along the Z axis, and an elastic element 14 is installed between the top rod 13 and the cross beam 11, the elastic element 14 has an internal force of elongating itself to lift the top rod 13 upward.

[0053] Specifically, referring to Figure 7 , the top of the backing plate module 12 is provided with a through guide hole 121, the top end of the guide hole 121 has an inwardly extending upper edge 122, the bottom of the top rod 13 is provided with an outwardly extending lower edge 131, the lower edge 131 is in sliding cooperation with the guide hole 121, and the upper edge 122 is used to prevent the top rod 13 from passing upward through the guide hole 121, thereby limiting the maximum upward movement stroke of the top rod 13.

[0054] In addition, referring to Figure 4 , the elastic element 14 adopts a tower spring, the spring force gradually increases when the tower spring is pressed, and vice versa, the spring force gradually decreases when the tower spring is elongated, so that the tower spring has a larger internal force when it is compressed, thereby being sufficient to drive the top rod 13 to rise to separate the busbar from the suction disc 3, and after the busbar is separated from the suction disc 3, the tower spring has a smaller internal force, thereby preventing the busbar from being excessively lifted upward.

[0055] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application, the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the embodiments of the present application.
