At present, in order to ensure the welding quality between the bus bar and the junction box in the photovoltaic module, a tin-adding welding mode is generally adopted, namely, a welding head is heated during welding, so that tin wires adhered on the bottom end face of the welding head are thermally fused for welding. However, in the soldering process, the terminal box is easily inclined or swayed, resulting in an inability to ensure the final soldering quality.

For this reason, a terminal block soldering machine for soldering a bus bar to a terminal block is proposed in the present embodiment; as shown in fig. 1-5, the terminal box tin-adding welder comprises a welding head 1, a transformation component and a centralizing component 4; the welding head 1 can move on the X axis, the Y axis and the Z axis, so that the welding head 1 can accurately move to a welding position on the junction box, and tin wires are adhered to the bottom end surface of the welding head 1; the welding head 1 is electrically connected with the transformer component, and the transformer component is used for heating the welding head 1 so as to enable tin wires on the welding head 1 to be melted; the welding head 1 is provided with a centralizing component 4 on two opposite sides, the centralizing component 4 can move along with the movement of the welding head 1, and the centralizing component 4 is used for horizontally pressing the top end face of the junction box before the welding head 1 is welded. In this embodiment, the bus bar is welded to the junction box by a common assembly method of the photovoltaic module in the prior art, and therefore, a detailed description of the welding principle between the bus bar and the junction box is omitted here. Wherein the X-axis, Y-axis and Z-axis are specifically shown by the arrows in fig. 1 and 2.

The welding head 1 is moved on the X axis, the Y axis and the Z axis so that the welding head 1 can accurately move to the welding position on the junction box and cover the welding position, tin wires are adhered to the bottom end surface of the welding head 1, the voltage transformation assembly is used for heating the welding head 1 so that the tin wires on the welding head 1 at the welding position are hot melted, then the heating is stopped and the welding head 1 is cooled so that the tin wires after the hot melting at the welding position are solidified, and therefore the tin adding welding between the bus bar and the junction box is completed.

Simultaneously, through all setting up righting subassembly 4 in the relative both sides of welding head 1, and righting subassembly 4 can follow the welding head 1 motion and move to make righting subassembly 4 can compress tightly on the terminal surface of terminal box horizontally before welding head 1 welds, make welding head 1 follow the Z axle decline and cover the welding position and carry out above-mentioned welding work again, thereby can avoid the terminal box in whole welding process to appear the problem of slope or rocking, and then can guarantee the welding quality between busbar and the terminal box.

Further, as shown in fig. 2-5, the welding head 1 can also rotate around the Z axis, the terminal box tin-adding welding machine further comprises a first connecting plate 5, and the first connecting plate 5 can drive the welding head 1 to move on the X axis, the Y axis and the Z axis and rotate around the Z axis, namely, the first connecting plate 5 is synchronous with the movement of the welding head 1; the righting component 4 comprises a guide pillar 41, an elastic piece 42, a fixed block 44 and a pressing plate 43, wherein the fixed block 44 is fixedly connected to the first connecting plate 5 and located on one side of the welding head 1, one end of the guide pillar 41 is fixedly connected to the fixed block 44, one end of the pressing plate 43 is slidably connected with the other end of the guide pillar 41, the other end of the pressing plate 43 can extend towards the welding head 1, the elastic piece 42 is sleeved on the guide pillar 41 and located between the fixed block 44 and the pressing plate 43, and the bottom end surface of the pressing plate 43 is lower than the bottom end surface of the welding head 1, so that the pressing plate 43 can be horizontally and elastically pressed on the top end surface of the junction box before the welding head 1.

Specifically, when the first connecting plate 5 drives the welding head 1 and the centralizing component 4 to move to the welding position, the welding head 1 and the centralizing component 4 continue to move downwards along the Z axis, and when the pressing plate 43 in the centralizing component 4 moves horizontally and is elastically pressed on the top end surface of the junction box, the welding head 1 does not completely cover the welding position at this time; and then the welding head 1 and the righting component 4 continue to move downwards along the Z axis until the welding head 1 completely covers the welding position, in the process, the pressing plate 43 can move upwards along the Z axis on the guide post 41 under the abutting action of the junction box so as to compress the elastic piece 42, so that the pressing plate 43 can be pressed on the top end surface of the junction box under the action of the elastic force of the elastic piece 42, and further the elastic pressing of the junction box is realized, so that the junction box can be well protected. In this embodiment, the elastic member 42 may be a compression spring.

It should be noted that, after the welding is completed, the first connecting plate 5 drives the welding head 1 and the righting component 4 to move upwards along the Z axis, and the welding head 1 breaks away from the junction box first step relative to the pressing plate 43, that is, in the whole process that the welding head 1 moves upwards along the Z axis to break away from the junction box, the pressing plate 43 can be always pressed against the junction box, so that the junction box can be prevented from being upwards carried up under the action force of the welding head 1 moving upwards along the Z axis, and further, the problem that the junction box is not deflected or rocked after the welding is completed can be ensured.

It should be noted that, in the whole welding process, the welding head 1 needs to be cooled twice, and the first cooling is that when the welding head 1 is adhered with tin wires, namely after the welding head 1 is heated for the first time, the insert 9 clamped at the bottom end surface of the welding head 1 can be heated to adhere the tin wires with melted surfaces, and then the welding head 1 is cooled rapidly for the first time, so that the insert 9 and the tin wires are solidified into a whole, and further the tin wires are adhered on the bottom end surface of the welding head 1; the second cooling is performed when the welding head 1 is welded, that is, when the welding head 1 is lowered to completely cover the welding position along the Z axis, the welding head 1 is heated for the second time, so that the tin wire on the insert 9 is quickly melted and overflowed to the welding position, and then the welding head 1 is quickly cooled for the second time, so that the tin wire at the welding position can be quickly solidified, and the welding work is completed.

Specifically, the vision assembly 19 includes a high-precision CCD camera fixedly connected to the third connection plate 13 and located at one side of the soldering head 1, and the CCD camera obtains a final detection result by photographing the soldering position, the tin wire and the soldering point on the junction box and comparing the images.

The specific welding process of the terminal box tin-adding welding machine in the embodiment is as follows:

firstly, after a tin wire is placed, a CCD camera is used for detecting the specific position of the tin wire and feeding back the specific position to a second driving piece 12, a fourth driving piece 16 and a fifth driving piece 18, so that the second driving piece 12, the fourth driving piece 16 and the fifth driving piece 18 sequentially drive a welding head 1 to move above the tin wire in all directions; then the second driving piece 12 drives the welding head 1 to move downwards along the Z axis to cover the tin wire; while the transformer assembly is first heated to the soldering joint 1, the tin wire is melted and adhered to the insert 9 on the soldering joint 1, and then the heating is stopped. Here, the heating temperature of the butt joint 1 is sufficient to ensure melting of the surface of the tin wire.

And then, the water cooling piece and the air cooling piece 8 are used for simultaneously cooling the welding joint 1 for the first time, so that the tin wire is solidified into an integrated structure with the insert 9 after being rapidly cooled, and then the welding joint 1 is moved upwards along the Z-axis to be lifted, thereby completing the adhesion of the tin wire.

Then, the CCD camera detects the specific welding position and feeds back the specific welding position to the second driving piece 12, the fourth driving piece 16 and the fifth driving piece 18, so that the second driving piece 12, the fourth driving piece 16 and the fifth driving piece 18 sequentially drive the welding head 1 to move in all directions; meanwhile, the third driving member 14 is used for driving the welding head 1 to perform position correction on the Y axis, and the first driving member 10 is used for driving the welding head 1 to perform rotation position correction around the Z axis, so that the welding head 1 can be ensured to be accurately moved to the position above the welding position.

Then, the second driving member 12 drives the welding head 1 to further descend along the Z axis, at this time, the pressing plate 43 of the centering assembly 4 also descends along the Z axis along with the welding head 1, and during the descending process, the pressing plate 43 contacts the junction box before the welding head 1; the pressing plate 43 can be pressed upwards by the abutting action of the junction box to compress the elastic piece 42, so that the pressing plate 43 can be horizontally and elastically pressed on the top end surface of the junction box under the elastic action of the elastic piece 42; the welding head 1 can be lowered to completely cover the welding position, the pressure transformation assembly is subjected to secondary heating to weld the welding head 1 so as to melt tin wires at the welding position, then the heating is stopped, the welding head 1 is subjected to secondary cooling, and the welding head 1 is rapidly cooled to solidification of the tin wires at the welding position through the water cooling piece and the air cooling piece 8.

Then, after the welding is completed, the welding head 1 is lifted upwards along the Z axial direction, and the pressure transformation assembly is used for heating the welding head 1 for the third time, so that the contact surface between the insert 9 of the welding head 1 and the welding position is hot-melted, and the welding head 1 is favorably separated from the welding point smoothly; in addition, in the process of rising upwards, the pressing plate 43 of the righting assembly 4 can be separated from the junction box after the welding head 1 is separated from the junction box upwards, namely, after the welding head 1 is separated from the junction box upwards, the pressing plate 43 is pressed against the top end surface of the junction box at the moment, so that the junction box is prevented from being carried up by the upward acting force of the welding head 1 after the welding is finished.

Finally, each driving piece drives the welding head 1 to move back to the upper part of the tin wire, and the steps of taking the tin wire and welding are repeated to carry out the next welding work; meanwhile, the CCD camera is used for detecting welding spots at the welding position so as to ensure the welding effect between the junction box and the bus bar.

The above process requires three heats, the first heat is low, i.e. the heating temperature of the butt joint 1 is low, so that the surface of the tin wire can be melted to facilitate the adhesion of the insert 9; the second heating is high, namely the heating temperature of the butt joint 1 is higher, so that the tin wire can be quickly melted for welding; the third heating is also low so that the welding head 1 can be detached from the welding spot relatively easily.

The foregoing is merely exemplary of the present utility model, and those skilled in the art should not be considered as limiting the utility model, since modifications may be made in the specific embodiments and application scope of the utility model in light of the teachings of the present utility model.
