[0033] The present application is further described in detail below in conjunction with the accompanying drawings.
[0034] See also Figure 1-3As shown, a positioning welding mechanism is shown, including a welding seat 1, a welder 2 which can be lifted and lowered on the welding seat 1, a driving module 3 for driving the welder 2 to lift and lower, and a positioning column 4 which is arranged at the bottom of the welder 2, and the positioning column 4 is arranged to be retractable along the vertical direction. Among them, the welder 2 is an electromagnetic welder 2, and a welding head 10 is arranged at the bottom of the welder 2. There are two positioning columns 4, and the two positioning columns 4 are respectively located on both sides of the welding head 10, and the positioning columns 4 and the welding head 10 are both located at the bottom of the side of the welder 2 away from the welding seat 1. When the welder 2 descends and welds the insulating strips and the busbars, the two positioning columns 4 can resist the insulating strips, effectively avoiding the relative offset between the insulating strips and the busbars, and improving the welding accuracy of the insulating strips.
[0035] In this embodiment, combined with Figure 2 As shown, two guide cylinders 5 corresponding to the two positioning columns 4 are also provided at the bottom of the welding machine 2. A spring (not shown in the figure) is provided in the guide cylinder 5. Each positioning column 4 is slidably inserted in the corresponding guide cylinder 5 along its axial direction and its upper end is connected to the spring. When the welding machine 2 descends, the positioning column 4 can slide upward in the guide cylinder 5 and squeeze the spring to prevent the positioning column 4 from interfering with the descent of the welding machine 2; and when welding, the positioning column 4 can be pressed against the insulating strip under the dual pressure of the welding machine 2 and the spring, effectively improving its positioning effect on the insulating strip.
[0036] In this embodiment, if Figure 1-2 As shown, the bottom of the welding machine 2 is also provided with a mounting groove 6, in which a fixing block 7 is embedded, and the fixing block 7 is connected to the welding machine 2 by bolts, and a first limiting groove 8 is provided on the fixing block 7, and a second limiting groove 9 is provided on the groove wall of the mounting groove 6, and the first limiting groove 8 and the second limiting groove 9 are both semi-circular arc-shaped, and the first limiting groove 8 and the second limiting groove 9 enclose a cylindrical limiting cavity, and the guide cylinder 5 is accommodated in the limiting cavity. In this way, by limiting the guide cylinder 5 through the limiting cavity, the installation strength of the guide cylinder 5 on the welding machine 2 can be effectively improved, and the guide cylinder 5 can be prevented from deflecting during the extension and retraction process of the positioning column 4, thereby improving the positioning effect of the positioning column 4 on the insulating strip.
[0037] In this embodiment, if Figure 2-3 As shown, the driving module 3 is a cylinder arranged on the welding seat 1, and a liftable slide 11 is arranged on the cylinder body of the cylinder, and the welding machine 2 is installed on the slide 11. The piston rod of the cylinder is telescopically arranged at the upper end of the cylinder body along the vertical direction, and a connecting seat 20 is arranged at the upper end of the slide 11, and the connecting seat 20 is connected to the piston rod of the cylinder. The slide 11 is driven to rise and fall by the cylinder, and the slide 11 drives the welding machine 2 to rise and fall.
[0038] Combination Figure 2As shown, a first guide groove 12 is opened along the vertical direction on the slide seat 11, and a first guide column 13 extending along the vertical direction is arranged on the cylinder body of the cylinder. The first guide column 13 includes two columns arranged side by side. The first guide column 13 is accommodated in the first guide groove 12 and is slidably connected to the first guide groove 12.
[0039] Two second guide columns 14 extending in the vertical direction are also provided in the first guide groove 12. The two second guide columns 14 are respectively located on both sides of the first guide column 13. A second guide groove 15 is opened on the cylinder body along the vertical direction. The two second guide columns 14 are respectively in conflict with the groove walls on both sides of the second guide groove 15.
[0040] In this way, the first guide groove 12, the second guide groove 15, the first guide column 13 and the second guide column 14 can limit and guide each other, effectively preventing the slide 11 from deviating during the lifting process, and improving the welding effect of the welding machine 2 on the insulating strip.
[0041] In this embodiment, combined with Figure 3 As shown, a guide rod 16 is provided at the upper end of the welding seat 1, and the guide rod 16 extends in the vertical direction. A guide hole 17 is also provided on the connecting seat 20, and the guide rod 16 is slidably inserted into the guide hole 17 along its axial direction. The guide rod 16 and the guide hole 17 cooperate with each other, which can further prevent the sliding seat 11 from deflecting during the lifting process.
[0042] In this embodiment, if Figure 1 and Figure 3 As shown, the welding seat 1 is also provided with two L-shaped wheel frames 21, one end of the wheel frame 21 extends from the welding seat 1 to the welding machine 2 and a rotatable running wheel 18 is provided at the end thereof, the two running wheels 18 are respectively located on both sides of the bottom of the welding machine 2, and the rotation axis of the running wheel 18 extends along the horizontal direction. A limit block 19 is also provided at the bottom of the welding machine 2, and the limit block 19 is located between the two running wheels 18 and on the side of the welding head 10 close to the welding seat 1.
[0043] The two walking wheels 18 can drive the welding machine 2 to approach the insulating strip in the horizontal direction, and the limit block 19 can limit the welding machine 2 in the horizontal direction, so as to facilitate the welding machine 2 to accurately weld the insulating strip; at the same time, during welding, the two walking wheels 18 can also be supported under the photovoltaic module to improve the stability of the photovoltaic module during welding.
[0044] The implementation principle of a positioning welding mechanism in the embodiment of the present application is:
[0045] During welding, the welding seat 1 is driven by the running wheels 18 to move horizontally toward the photovoltaic module. When the limit block 19 contacts the side of the photovoltaic module, the welding seat 1 stops moving.
[0046] The driving module 3 drives the welding machine 2 to descend. During the descent of the welding machine 2, the positioning column 4 contacts the insulating strip in advance. Then, the welding machine 2 continues to descend, and the positioning column 4 is continuously compressed until the welding head 10 contacts the insulating strip.
[0047] The positioning column 4 is pressed against the insulating strip under the action of the spring and the welding machine 2, and the welding head 10 welds the insulating strip;
[0048] After welding is completed, the driving module 3 drives the welding machine 2 to rise, and then the welding seat 1 is driven by the walking wheels 18 to move away from the photovoltaic module.
[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
