Description

Technical Field

[0001] This utility model relates to the field of solar cell technology, and in particular to a cutting device for solar cell production. Background Technology

[0002] In the field of solar cell manufacturing, the cutting process is a crucial step affecting cell quality and production efficiency. While traditional laser cutting technology offers advantages such as speed and precision, the high temperatures generated during the cutting process can cause micro-cracks and thermal damage at the cell edges, severely impacting the cell's mechanical strength and photoelectric conversion efficiency. Statistics show that solar cells cut using laser technology have an average fragmentation rate exceeding 1.2%, and a heat-affected zone width exceeding 100μm. This not only increases production costs but also hinders further improvements in cell performance. However, existing cutting equipment for solar cell production still suffers from problems such as unstable cell clamping, inconsistent and continuous cell transport, and inaccurate cell cutting.

[0003] Therefore, it is essential to invent a cutting device for the production of solar cells. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a cutting device for solar cell production, solving the issues that existing solar cell cutting devices still suffer from instability in clamping solar cells, instability in continuously transporting solar cells, and instability in accurately cutting solar cells. A cutting device for solar cell production includes a solar cell conveyor belt, an auxiliary support conveyor belt, solar cells, a support frame, a drive track, a waterjet cutting structure, and a water inlet pipe. The solar cell conveyor belt and the auxiliary support conveyor belt are mounted side-by-side on the ground via a bracket, with the solar cells clamped inside the solar cell conveyor belt and the auxiliary support conveyor belt. The support frame is fixedly mounted on the outside of the solar cell conveyor belt and the auxiliary support conveyor belt. The drive track is fixedly mounted above the support frame, and the waterjet cutting structure is slidably mounted on the drive track. The water inlet pipe is fixedly mounted above the waterjet cutting structure.

[0005] The battery cell conveyor belt includes a support base, a positioning support plate, a first conveyor belt and a second conveyor belt, with the support base fixedly installed at both ends of the positioning support plate, and the first and second conveyor belts installed inside the support base.

[0006] The waterjet cutting structure includes an inner substrate, an outer substrate, a sliding wheel, and a waterjet structure. The inner substrate is fixedly installed on both sides of the waterjet structure, and the outer substrate is located outside the two sets of inner substrates. The sliding wheel is rotatably installed between the inner substrate and the outer substrate, and the sliding wheel is slidably installed on the drive rail.

[0007] The internal structure of the battery cell conveyor belt is completely identical to that of the auxiliary support conveyor belt. The first and second conveyor belts can clamp one side of the battery cell, and the auxiliary support conveyor belt clamps the other side of the battery cell. The positioning support plate is made of a set of stainless steel metal plates, and a guide slope is provided on the inner side of the entry end of the positioning support plate.

[0008] The water jet cutting structure can reciprocate on the drive track, and the direction of movement of the water jet cutting structure is consistent with the direction of movement of the battery cell. The sliding wheel is composed of several sets, one of which can be driven to rotate actively by a motor to form a drive wheel; the water outlet of the water jet structure faces directly downward, and the water jet structure is perpendicular to the battery cell.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The battery cell conveyor belt of this utility model works in conjunction with the auxiliary support conveyor belt to achieve bilateral clamping and fixing of the battery cells using the first and second conveyor belts, and is precisely positioned by the 30° guide slope of the positioning support plate; its support base ensures that the parallelism error of the conveyor belt is <0.1mm, and at the same time keeps the movement speed of the water jet cutting structure on the drive track synchronized. Under the stable support of the support frame, vibration is effectively suppressed, and finally high-precision, non-destructive cutting of the battery cells is achieved.

[0010] The water jet cutting structure of this utility model uses a rigid frame composed of an inner and outer substrate, combined with the precise movement of sliding wheels on a drive track, to drive the water jet structure to complete high-pressure water jet cutting. The water jet structure uses a sapphire nozzle to spray vertically downwards, achieving cold cutting under continuous water supply from the inlet pipe, effectively avoiding thermal damage. At the same time, the active drive of the sliding wheels achieves synchronous control with the speed of the battery cell conveying, ensuring the quality of the cut. Attached Figure Description
