[0039] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0040] like Figure 1-4 As shown, a busbar welding probe welding device includes a connecting base 1; it also includes: a fixed mounting component 3, which is fixedly installed to one side of the bottom of the connecting base 1; a plurality of movable mounting components 4 that can be detached from the connecting base 1 are provided on one side of the fixed mounting component 3, and the plurality of movable mounting components 4 are slidably installed to the bottom of the connecting base 1 to adjust the spacing between adjacent movable mounting components 4 and the spacing between the movable mounting components 4 and the fixed mounting component 3; an elastic clamping mechanism, which is installed on the connecting base 1, and the height of the top end of the elastic clamping mechanism is greater than the height of the top surface of the connecting base 1; the bottom end of the elastic clamping mechanism is in contact with the top end of the movable mounting components 4; and probes 2, which are installed on the fixed mounting component 3 and the plurality of movable mounting components 4, and the probes 2 are vertically arranged.

[0041] like Figure 1-3As shown, the fixing mounting component 3 includes a fixing base 301 and a fixing strip 302. The fixing strip 302 is fixedly connected to the bottom surface of the connecting base 1, and the bottom end of the fixing strip 302 is fixedly connected to the top surface of the fixing base 301.

[0042] The movable mounting component 4 includes a movable base 401 and a movable strip 402; the bottom end of the movable strip 402 is fixedly connected to the top surface of the movable base 401.

[0043] The probe 2 is provided with a pressure head 201 at its bottom end, and the top end of the probe 2 is connected to the fixed seat 301 of the fixed mounting component 3 and the movable seat 401 of the movable mounting component 4.

[0044] The fixed mounting part 3 is fixed to one side of the bottom of the connecting seat 1, while the movable mounting part 4 is designed to slide along the length of the connecting seat 1, so as to adjust the distance between adjacent movable mounting parts 4, as well as the distance between the movable mounting part 4 and the fixed mounting part 3; thereby realizing the adjustment of the distance between the probes 2.

[0045] The movable mounting part 4 can be removed and reinstalled after removal, thereby adjusting the number of probes 2 on the entire device.

[0046] By adjusting the number and spacing of probes 2 as described above, the welding requirements of solar cells with different grid numbers can be met.

[0047] During welding, probe 2 presses the welding strip and busbar with pressure head 201 below it.

[0048] like Figure 1 and Figure 3 As shown, a plurality of horizontally arranged guide posts 5 are fixedly installed on the side of the fixed strip 302, and a guide hole 403 is provided on the movable strip 402, and the guide post 5 is connected to the guide hole 403.

[0049] By setting the guide post 5 and the guide hole 403, the movable strip 402 can slide on the guide post 5. At the same time, the end of the guide post 5 away from the fixed strip 302 is designed to be unobstructed, so the movable strip 402 can be detached from the guide post 5 away from the fixed strip 302 and reinstalled. This realizes the removal and reinstallation of the movable mounting part 4 to adjust the number of probes 2.

[0050] like Figure 1 , Figure 3 as well as Figure 4The elastic pressing mechanism includes an elastic pressing member 6 and a pressing plate 7; the bottom surface of the pressing plate 7 abuts against the top surface of the movable strip 402, and a plurality of equally spaced positioning inserts 701 are fixedly installed on the top surface of the pressing plate 7. A plurality of positioning holes 103 are opened on the bottom surface of the connecting seat 1, and the bottom end of the positioning hole 103 is connected to the positioning insert 701. There are multiple elastic pressing members 6, and the multiple elastic pressing members 6 abut against the top surface of the multiple positioning inserts 701 respectively.

[0051] The elastic pressure member 6 includes a straight tube 601 and a pressure plate 602; a plurality of recessed holes 102 are provided on the top surface of the connecting seat 1, the diameter of the recessed holes 102 is equal to the diameter of the pressure plate 602, and the recessed holes 102 are located below the pressure plate 602. The straight tube 601 is fixedly connected to the bottom of the pressure plate 602. A guide groove 104 is provided between the recessed holes 102 and the positioning holes 103, and the recessed holes 102 and the positioning holes 103 are connected through the guide groove 104. The straight tube 601 is connected to the guide groove 104. A retaining ring 604 is fixedly installed on the outer edge of the bottom end of the straight tube 601. The outer ring wall of the retaining ring 604 is connected to the positioning hole 103. A spring 603 in a compressed state is provided inside the straight tube 601.

[0052] The two ends of the spring 603 abut against the bottom surface of the pressure plate 602 and the top surface of the positioning insert 701, respectively.

[0053] The diameter of the recessed hole 102 and the diameter of the positioning hole 103 are both larger than the diameter of the guide groove 104.

[0054] The connector 1 has four mounting holes 101, and the four mounting holes 101 are located at the four corners of the connector 1.

[0055] The elastic clamping mechanism is used to clamp the movable strip 402 to achieve clamping and positioning of the movable mounting part 4 after adjustment. The elastic clamping mechanism does not require active operation. During the process of fixing the connecting seat 1 to the external mounting surface, the elastic clamping part 6 of the elastic clamping mechanism is squeezed by the mounting surface to compress and achieve clamping and positioning.

[0056] like Figure 1 and Figure 3As shown, the entire device is in a disassembled state at this time. The top of the pressure plate 602 and the straight tube 601 of the elastic pressure member 6 are both located above the top surface of the connecting seat 1. Screws or bolts are inserted through the mounting hole 101 to install the connecting seat 1 on the mounting surface. The top surface of the connecting seat 1 is in contact with the mounting surface. During the above installation process, the mounting surface pushes the pressure plate 602 and the straight tube 601. The pressure plate 602 enters the recessed hole 102, and the straight tube 601 moves downward, compressing the spring 603. The spring 603 is fully compressed. Through the compression force, the positioning recess 701 is pressed, so that the pressing plate 7 is pressed against the top surface of the movable strip 402 to achieve pressing and positioning.

[0057] Disassemble connector 1, remove the entire device, and then adjust the number and spacing of probes 2 on the entire device. After the entire device is disassembled, the top surface of pressure plate 602 loses pressure, and the spring force of spring 603 causes pressure plate 602 and straight tube 601 to reset, reducing the compression of spring 603 and restoring it to its original state. Figure 3-4 This reduces the pressure on the top surface of the movable strip 402, thus losing its clamping and positioning function.

[0058] It should be noted that, in such cases Figure 3-4 In the state shown, the spring 603 is also in a compressed state, but its compression is much less than that of the fully compressed state. The spring force of the compression makes the pressure plate 7 and the top surface of the movable bar 402 fit together, and the two maintain a certain pressure, which increases the friction. After the probe 2 is adjusted, the possibility of non-human movement of the probe 2 due to vibration is reduced.

[0059] The straight tube 601 and the guide groove 104 cooperate to guide the vertical movement of the straight tube 601; the positioning insert 701 cooperates with the positioning hole 103 to provide positioning for the clamping plate 7.

[0060] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
