Description

Technical Field

[0001] The present invention relates to the technical field of silicon wafer string welding, and in particular to a welding wire clamping structure. Background Art

[0002] Photovoltaic solar wafers are the core and most valuable component of solar power generation systems. The wafer's function is to convert solar energy into electricity, which is then stored in batteries or used directly as a load. In BC batteries (back-contact batteries, which can be combined with various circuits), before string welding, the welding wire must be pulled from the wire reels in the wire feeders on both sides. Since wire pulling is required on both sides, the two wire clamping and pulling structures consume considerable structural resources and interfere with each other's travel, failing to meet bilateral requirements. Summary of the Invention

[0003] One object of the present invention is to provide a welding wire clamping structure that completes the welding wire stretching action on both sides through the same clamping support, wherein a cylinder is used to drive the welding wire upper clamp to achieve swing, and together with the fixed welding wire lower clamp, the end of the welding wire is clamped.

[0006] As a preferred technical solution, the upper end of each clamping cylinder is connected to two support air pipe joints, both of which are connected to the support cavity, one support air pipe joint for air intake and the other support air pipe joint for air outlet.

[0007] As a preferred technical solution, a fixed rib is provided in the middle of the welding wire clamping support, and the two groups of clamping cylinders are respectively located on both sides of the fixed rib.

[0008] As a preferred technical solution, connecting rods are installed on both sides of the welding wire clamping support, and the middle part of the welding wire upper clamp is rotatably connected to the connecting rods.

[0009] As a preferred technical solution, connecting sheets are formed on both sides of the upper end of the welding wire upper clamp, and a connecting groove is provided on the side of the outer end of the welding wire movable shaft, and the connecting sheet is located in the connecting groove.

[0010] The beneficial effects of the present invention are: providing a welding wire clamping structure, which controls the swing of the entire row of welding wire upper clamps through an integrated clamping cylinder, and under the action of the lever principle, the welding wire upper clamp and the fixed welding wire lower clamp jointly clamp the end of the welding wire, making it easy to stretch it to the required length.

[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0017] like Figures 1 to 2 As shown, in this embodiment, a welding wire clamping structure includes a welding wire clamping support 1 and two groups of clamping cylinders 2, the clamping cylinders 2 are fixed to the upper end of the welding wire clamping support 1, and each group of clamping cylinders 2 is provided with a plurality of welding wire movable shafts 3 distributed along the length direction, the welding wire movable shafts 3 are laterally extended and retracted in the clamping cylinders 2, and a row of welding wire lower clamps 4 and a row of welding wire upper clamps 5 are installed on both sides of the welding wire clamping support 1, the welding wire lower clamps 4 are fixed on the welding wire clamping support 1, and a support cavity is provided inside the welding wire clamping support 1, the upper end of the welding wire upper clamp 5 is hinged to the end of the welding wire movable shaft 3, and the middle part of the welding wire upper clamp 5 is hinged to the welding wire clamping support 1.

[0018] The entire welding wire clamping support 1 moves to the left and right sides respectively to clamp and stretch the end of the welding wire. When clamping the end of the welding wire, the upper welding wire clamp 5 is in the open state, and the clamping cylinder 2 is ventilated so that the air pressure in the support cavity pushes out the welding wire movable shaft 3. When the upper end is connected to the welding wire movable shaft 3, the middle part of the upper welding wire clamp 5 begins to swing downward around the welding wire clamping support 1, and the lower end of the upper welding wire clamp 5 will clamp the welding wire together with the lower welding wire clamp 4 to assist the pulling-out action, so that the operation of pulling the welding wire on both sides can be realized on the same welding wire clamping support 1, saving structure.

[0019] The upper end of each clamping cylinder 2 is connected to two support air pipe joints 6, and the two support air pipe joints 6 are connected to the support cavity. One support air pipe joint 6 is for air intake, and the other support air pipe joint 6 is for air discharge, so as to meet the upward opening and downward clamping of the welding wire clamp 5.

[0020] A fixed rib 7 is provided in the middle of the welding wire clamping support 1, and two groups of clamping cylinders 2 are respectively located on both sides of the fixed rib 7. Under the action of the fixed rib 7, the overall structure is more stable and is not affected by the pulling of the welding wire on both sides.

[0021] Connecting rods 8 are installed on both sides of the welding wire clamping support 1, and the middle part of the welding wire upper clamp 5 is rotatably connected to the connecting rod 8. The existence of the connecting rod 8 enables the entire row of welding wire upper clamps 5 on the same side to swing synchronously, and multiple welding wires can be pulled at the same time.

[0022] Connecting plates 9 are formed on both sides of the upper end of the welding wire upper clamp 5, and a connecting groove 10 is provided on the outer end side of the welding wire movable shaft 3. The connecting plate 9 is located in the connecting groove 10. The above structure is easy to install, and the welding wire upper clamp 5 with the connecting plate 9 can be driven to move only by relying on the connecting groove 10 of the welding wire movable shaft 3.

[0023] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be covered within the scope of protection of the present invention.
