FIG. 1 is a side view of a junction box welding robot in an embodiment of the invention; fig. 3 is a schematic view of a terminal box welding manipulator in a use state according to an embodiment of the invention. As shown in fig. 1 and 3, the present embodiment provides a terminal box welding manipulator, including: a body 1; wherein, the body 1 may be a plate-shaped structure, the heating structure may be disposed on one of the plate surfaces of the body 1, and the heating structure is at least partially located at the bottom end of the body 1, and is suitable for heating the transmission member in the junction box 13 to be welded; the transmission member is an electrode 16 on the junction box and a tin block 18 covered on the surface of the electrode 16. Upon heating, the tin bump 18 on the surface of the electrode 16 may be melted.
The pressing structure may be disposed on another plate surface of the body 1, capable of moving relative to the body 1, and at least partially capable of extending to one end of the body 1 opposite to the heating structure portion, and applies pressure to the lead-out member on the solar cell module, so that the lead-out member is in close contact with the transmission member. The drawing member is a bus bar 15 on the solar cell module. After the tin block 18 cools and the busbar 15 and the electrode 16 are bonded together, the pressing structure returns to the initial position and the busbar 15 is stopped from being pressed.
According to the junction box welding manipulator provided by the invention, the pressing structure is arranged on the body 1, when the heating structure heats the transmission piece, the pressing structure is used for applying pressure to the extraction piece, so that the extraction piece is in close contact with the transmission piece, and after the tin block 18 in the transmission piece is completely melted, the heating structure is evacuated. During the cooling of the tin block 18, the pressing structure keeps pressing the drawing member until the tin block 18 is cooled and solidified, and the pressing structure returns to the initial position to stop applying pressure to the drawing member. So set up, after heating structure withdraws, the push-down structure still keeps pushing down to the drawing member, prevents to draw member when upwarping and the separation of uncooled tin 18 caused the rosin joint, is favorable to improving the welding quality of product.
The pressing structure comprises a fixed seat 2, a pressing needle 4 and a first driving piece 3; the fixing base 2 may be an annular structure, and the fixing base 2 is fixedly connected to the body 1, for example, may be welded on a side surface of the body 1. The first driving element 3 may be an air cylinder, the cylinder body of the air cylinder is inserted into the annular fixing seat 2, and the cylinder body of the air cylinder may be fixed on the fixing seat 2 through bolts. The telescopic head of cylinder is outwards extended for the cylinder, and the terminal box is located the below of cylinder for when the telescopic head of cylinder outwards stretches out, can drive pressure needle 4 to stretch to the drawing-out piece, presses the drawing-out piece on the terminal box. The pressing needle 4 can be connected with a screw or welded on a telescopic head of the air cylinder. Wherein, the pressing needle 4 can be in a cylindrical structure. In use, the first driving member 3 can drive the pressing needle 4 to make telescopic movement, so that the pressing needle 4 presses the bus bar 15 or is retracted to be separated from pressing the bus bar 15.
In this embodiment, in order to prevent the tin block 18 from adhering to the pressing needle 4, the ceramic block 5 may be installed at the end of the pressing needle 4 far away from the first driving member 3, and the ceramic block 5 may entirely cover the end surface of the pressing needle 4, when the pressing needle 4 presses the lead-out member, the ceramic block 5 is not easy to adsorb the tin block 18, so that adhesion or loss of the tin block 18 may be avoided, and meanwhile, the phenomenon of rough and unsmooth welding surface is avoided, so as to improve welding quality and welding aesthetic degree.
Wherein, heating structure includes soldering bit 8, heater 7 and second driving piece 6, and second driving piece 6 also can be the cylinder, and the cylinder body of cylinder can direct welding be on body 1, and the telescopic head spiro union of heater 7 one end and cylinder, the other end and soldering bit 8 contact connection. The soldering bit 8 is arranged at one end of the heater 7 far away from the body 1, and under the action of the second driving piece 6, the soldering bit 8 can be moved to a target position in the extending direction parallel to the body 1 to heat the transmission piece. When in use, the heater 7 can be driven to move up and down through the second driving piece 6, so as to drive the soldering bit 8 connected with the heater 7 to move up and down. When the tin block 18 on the junction box 13 needs to be heated, the soldering bit 8 descends and contacts with the tin block 18, meanwhile, the pressing needle 4 stretches out to press the converging strip 15, after the tin block 18 is completely melted, the soldering bit 8 ascends, the pressing needle 4 continuously presses the converging strip 15 until the tin block 18 is completely cooled and solidified, and the pressing needle 4 is retracted.
As shown in fig. 3, during welding, the junction box 13 is located on the surface of the solar cell module 14, the top of the junction box 13 is of an open structure, the bottom in the box body of the junction box 13 is provided with a diode 17, an anode and a cathode (one of which is the electrode 16 shown in fig. 3), one side of the diode 17 is connected with the anode, and the other side is connected with the cathode. The two bus bars 15 of the solar cell module 14 are respectively connected with the anode and the cathode of the cell sheet forming the solar cell module 14, and then extend upwards into the box body of the junction box 13 through the bottom reserved hole of the junction box 13, and each bus bar 15 corresponds to one electrode 16. The positive electrode and the negative electrode of the junction box 13 are relatively close, the surfaces of the junction box are respectively wrapped with a tin block 18, and the bus bar 15 at least partially extends to be located above the tin blocks 18. During welding, the soldering bit 8 presses the busbar 15 to enable the busbar 15 to be in contact with the tin block 18, meanwhile, the pressing needle 4 synchronously presses the busbar 15, after the tin block 18 melts, the soldering bit 8 rises, and the pressing needle 4 continues to press the busbar 15 until the tin block 18 cools.
Due to the compact design of the junction box 13, the electrode 16 and the busbar 15 of the junction box 13 are smaller in size and smaller in area design for welding. Therefore, the position matching requirements for the soldering bit 8, the leading-out piece and the transmission piece are higher, the requirement for quick and full melting of the tin block below the soldering bit 8 after the soldering bit 8 contacts with the converging belt 15 is met on the converging belt 15 with limited contact area, and meanwhile, the contact degree between the pressing needle 4 and the converging belt 15 in the welding process is met and the converging belt 15 cannot tilt upwards after the welding is finished. That is, the contact points of the soldering bit 8 and the bus bar 15, and the contact points of the pressing pins 4 and the bus bar 15 are distributed and matched at different positions on the bus bar 15, which puts high demands on the positions of the soldering bit 8 and the pressing pins 4 of the soldering manipulator. Ensure that the soldering bit 8 contacts with the bus bar 15 and the tin block 18, when the tin block 18 is heated, the pressing needle 4 can extend out to effectively press the bus bar 15, and meanwhile, the movement or the heating effect of the soldering bit 8 cannot be interfered because of the existence of the pressing needle 4. The welding head 8 and the pressing needle 4 can be matched with each other to realize welding work, and the welding head can return to the initial position to prepare the next welding work after the respective work is completed. Therefore, in this embodiment, besides the pressing needle 4 and the soldering bit 8 are located on different sides of the body 1, a certain inclination angle can be formed between the first driving member 3 and the body 1, so that the pressing needle 4 can be more close to the center position of the converging belt 15 and the tin block 18 after extending out, the pressing effect is improved, and the movement of the soldering bit 8 is not disturbed. Wherein the angle of inclination may be in the range of 15 deg. -45 deg., for example, the angle of inclination may be 30 deg..
Fig. 2 is a front view of a welding manipulator for a junction box according to an embodiment of the present invention, as shown in fig. 2, in which, a tin-collecting groove 11 is disposed at an end of the soldering iron tip 8 away from the heater 7, the tin-collecting groove 11 is located on a side wall of the soldering iron tip 8 facing the press pin 4, for example, the tin-collecting groove 11 may be located at a middle position of the side wall, and the tin-collecting groove 11 extends to a bottom edge of the soldering iron tip 8 along a length direction of the soldering iron tip 8. The depth of the concave portion of the tin-gathering groove 11 toward the soldering bit 8 can be designed according to the size of a transmission piece, the width of the tin-gathering groove 11 can be between the width of the converging belt 15 and the width of the soldering bit 8, so that when the soldering bit 8 contacts with the transmission piece, the transmission piece is integrally positioned in the tin-gathering groove 11, after the tin block 18 melts, the tin cannot flow around under the limitation of the groove wall of the tin-gathering groove 11, so that tin outflow is prevented, the tin storage amount on the surface of the converging belt 15 after welding is increased, the welding strength is improved, the welding yield is improved, and an area for pressing the contact point of the needle 4 and the converging belt 15 can be reserved on the surface of the converging belt 15.
The slot wall of the tin-gathering slot 11 facing the surface of the pressing needle 4 is an inclined plane, and the inclined plane is parallel to the straight line where the pressing needle 4 is positioned. When the push pin 4 needs to press the lead-out member, the push pin 4 is inserted into the tin bath 11 and presses the lead-out member. At this time, the contact point of the pressing needle 4 and the drawing member is closer to the center position of the drawing member, so that the pressing force of the pressing needle 4 on the drawing member is more uniform, and the pressing effect is improved.
In this embodiment, the heating structure further includes a temperature sensor 9 disposed on the soldering bit 8, and the temperature sensor 9 may be connected to the controller of the heater 7 through a signal transmission line 12. The temperature sensor 9 collects real-time temperature values of the soldering bit 8 and feeds the temperature values back to the controller of the heater 7, and the controller can adjust heating power of the heater 7 according to the fed-back temperature values, so that the temperature of the soldering bit 8 is adjusted, and the temperature of the soldering bit 8 is kept stable. Wherein, the heater 7 may be an electric heater 7, and the controller may change the power of the electric heater 7 by adjusting the operation current of the electric heater 7.
In this embodiment, the welding manipulator for a junction box further includes an air-cooled pipeline 10, for example, the air-cooled pipeline 10 may be disposed on the body 1, an air inlet end of the air-cooled pipeline 10 is connected to an air source, and an air outlet end of the air-cooled pipeline 10 is disposed towards the pressing structure, so that the electrode 16 and the tin block 18 on the junction box are accelerated to be cooled when the pressing structure is in the first state. The air cooling pipeline 10 and the pressing needle 4 can be located on the same side of the body 1. After the soldering bit 8 is lifted upwards, the air cooling pipeline 10 starts to blow air, the cooling of the tin block 18 at the welding position is accelerated, and after the tin block 18 is cooled and solidified, air supply is stopped.
In this embodiment, the relative positions of the soldering bit 8 and the pressing pin 4 can be adaptively adjusted for the terminal boxes with different specifications. Meanwhile, since the junction box is provided with the positive electrode and the negative electrode which correspond to the anode and the cathode of the battery assembly respectively, the number of the soldering tips 8 and the pressing pins 4 can be designed according to the numbers of the bus bars 15 and the tin blocks 18, that is, for the junction box comprising the positive electrode and the negative electrode, two welding manipulators can be arranged side by side, and thus the tin blocks 18 on the surfaces of the corresponding electrodes 16 are heated respectively through the two soldering tips 8 respectively. Similarly, two pressing needles 4 arranged side by side can respectively press the corresponding bus belts 15; the two air-cooled lines 10 arranged side by side can cool the respective corresponding tin blocks 18. Therefore, the welding manipulator can finish all operations related to welding of the anode and the cathode in one junction box in one pressing and heating process, and the working efficiency is improved.
