Description

Technical Field

[0001] This utility model relates to the technical field of silicon wafer string bonding, and in particular to a wire clamping structure. Background Technology

[0002] Photovoltaic silicon wafers are the core and most valuable component of a solar power generation system. Their function is to convert solar energy into electrical energy, which is then stored in batteries or used directly as a power source. In BC cells (back-contact cells, which can be combined with various circuits), before string welding, the welding wire needs to be drawn from the wire coils on both sides of the wire feeder. Since both sides need to be wire-drawn, the two wire-drawing structures consume significant structural resources and interfere with each other in terms of travel, failing to meet the requirements for both sides. Utility Model Content

[0003] One objective of this utility model is to provide a wire clamping structure that completes the wire stretching action on both sides through the same clamping support, wherein the upper wire clamp is driven by a cylinder to achieve oscillation, and together with the fixed lower wire clamp, it clamps the end of the wire.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A welding wire clamping structure includes a welding wire clamping support and two sets of clamping cylinders. The clamping cylinders are fixed to the upper end of the welding wire clamping support. Each set of clamping cylinders has several welding wire movable shafts distributed along its length. The welding wire movable shafts extend and retract laterally within the clamping cylinders. A row of lower welding wire clamps and a row of upper welding wire clamps are installed on each side of the welding wire clamping support. The lower welding wire clamps are fixed to the welding wire clamping support. The welding wire clamping support has a support cavity inside. The upper end of the upper welding wire clamp is hinged to the end of the welding wire movable shaft, and the middle part of the upper welding wire clamp is hinged to the welding wire clamping support.

[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, with one support air pipe joint for air intake and the other support air pipe joint for air outlet.

[0007] As a preferred technical solution, the welding wire clamping support is provided with a fixing rib in the middle, and the two sets of clamping cylinders are respectively located on both sides of the fixing 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 clamp is rotatably connected to the connecting rods.

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

[0010] The beneficial effects of this utility model are as follows: It provides a wire clamping structure, which controls the swing of the upper clamp of the entire row of welding wires through an integrated clamping cylinder. Under the action of the lever principle, the upper clamp of the welding wire and the fixed lower clamp of the welding wire jointly clamp the end of the welding wire, which makes it easy to stretch to the required length.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 2 As shown in this embodiment, a wire clamping structure includes a wire clamping support 1 and two sets of clamping cylinders 2. The clamping cylinders 2 are fixed to the upper end of the wire clamping support 1. Each set of clamping cylinders 2 has several wire movable shafts 3 distributed along the length direction. The wire movable shafts 3 extend and retract laterally in the clamping cylinders 2. A row of lower wire clamps 4 and a row of upper wire clamps 5 are installed on each side of the wire clamping support 1. The lower wire clamps 4 are fixed on the wire clamping support 1. The inside of the wire clamping support 1 is provided with a support cavity. The upper end of the upper wire clamp 5 is hinged to the end of the wire movable shaft 3, and the middle part of the upper wire clamp 5 is hinged to the wire clamping support 1.

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

[0019] Each clamping cylinder 2 has two support air pipe joints 6 connected to its upper end. Both 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 exhaust, so as to satisfy the upward opening and downward clamping action of the welding wire clamp 5.

[0020] The wire clamping support 1 has a fixed rib 7 in the middle. Two sets of clamping cylinders 2 are 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 wire pulling on both sides.

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

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

[0023] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
