Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic cell processing, and specifically relates to an automatic stacking device for non-compliant photovoltaic cell strings. Background Technology

[0002] A crystalline solar panel is a device that converts solar energy into electrical energy using the photovoltaic effect. Also known as a photovoltaic solar panel, it typically consists of multiple photovoltaic cells that absorb sunlight and convert it into direct current (DC) electricity. These panels can be installed on rooftops, the ground, or other suitable areas of buildings to generate or supply electricity. As an important means of clean energy generation, photovoltaic solar panels are receiving increasing attention and are being widely used.

[0003] During the processing of crystalline solar cells, it is usually necessary to inspect the cell strings with attached busbars for compliance. If any are found to be non-compliant (NG), they must be separated from the compliant ones and reworked. In existing technology, the separation of NG cell strings is typically done manually by removing them directly from the conveyor line, while compliant strings continue to be conveyed forward. This method requires additional manual labor to re-sort the removed NG cell strings, making the process more cumbersome and increasing labor costs. Therefore, this invention provides an automatic stacking device for NG photovoltaic cell strings. Utility Model Content

[0004] To address the aforementioned issues, this invention provides an automatic stacking device for non-compliant (NG) photovoltaic cell strings. This device can automatically lift and stack NG cells without manual collection. After stacking, the NG cell strings are arranged in an orderly manner, facilitating subsequent rework operations. It is more convenient to use and saves labor costs.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic stacking device for non-compliant photovoltaic cell strings includes a conveying mechanism, a conveyor line, and a stacking mechanism. The conveying mechanism is located at the front end of the conveyor line, which includes a main conveyor line and an auxiliary conveyor line. The main conveyor line consists of two four-segment conveyor belts, and the auxiliary conveyor line consists of three-segment conveyor belts. A gap is provided between the two four-segment conveyor belts, and the stacking mechanism is located within the gap.

[0007] As a preferred technical solution, the system also includes a frame, in which the conveying mechanism, conveyor line, and stacking mechanism are disposed.

[0008] As a preferred technical solution, both the main conveyor line and the auxiliary conveyor line are connected by a motor, a main drive shaft, and a driven shaft.

[0009] As a preferred technical solution, the conveying mechanism includes a telescopic end and a fixed end, the fixed end is connected to the conveyor line, the telescopic end and the fixed end are slidably connected, the telescopic end is provided with a conveying roller and a conveying guide wheel, and the fixed end is provided with a limit switch for controlling the sliding extension and retraction of the telescopic end.

[0010] As a preferred technical solution, auxiliary support discs are provided on both sides of the conveying roller.

[0011] As a preferred technical solution, a gripping handle is provided at the front of the telescopic end.

[0012] As a preferred technical solution, a limiting block is provided at the fixed end for limiting the extension and retraction of the telescopic end.

[0013] As a preferred technical solution, the stacking mechanism includes a stepper motor, a transmission belt, a support frame, and a stacking bracket. The stepper motor is connected to the stacking bracket via the transmission belt. The support frame has slide rails on both sides, and the stacking bracket is slidably connected to the slide rails. The stacking bracket has several stacking columns, and a stacking position is formed between two adjacent stacking columns. The stacking position is located in the gap between the two four-segment conveyor belts.

[0014] As a preferred technical solution, the stack support is provided with 20 stack positions.

[0015] As a preferred technical solution, a CCD camera is also installed above the conveyor line.

[0016] Beneficial effects:

[0017] This invention utilizes a conveying mechanism to transport battery strings to other workstations. The main and auxiliary conveyor lines connect to this mechanism. During transport, if the CCD camera detects a qualified battery string, it is conveyed out from the other end of the conveyor line. If a non-compliant battery string is detected, a stacking mechanism lifts and separates the non-compliant battery strings one by one on the conveyor line for stacking. The conveying mechanism features a telescopic design, retracting into the frame for easy access by maintenance personnel during equipment maintenance. This facilitates maintenance and allows for the automatic lifting and stacking of non-compliant battery strings without manual collection.

[0028] During operation, the battery string is transferred to other workstations via the conveyor mechanism 2.

If the CCD camera detects that the battery string is qualified during the transfer process, it is transferred out from the other end of the conveyor line 3.

Specifically, the telescopic end 21 and the fixed end 22 can be slidably connected via slide rails and sliders, allowing the telescopic end 21 to slide relative to the fixed end 22. The telescopic end 21 can be driven to slide by a cylinder or manually pushed. The telescopic end 21 is equipped with a conveying roller 23 and a conveying guide wheel 24, and the fixed end 22 is equipped with a limit switch 27 for controlling the sliding extension and retraction of the telescopic end 21. The telescopic end 21 can extend and retract along the fixed end 22, controlled by the limit switch 27.

[0032] Specifically, auxiliary support discs 25 are provided on both sides of the conveying roller 23, and the auxiliary support discs 25 play a supporting role in conveying.

[0033] Specifically, a gripping handle 26 is provided at the front of the telescopic end 21, which can be used to push the telescopic end 21 to slide, thereby retracting it into the frame 1.

[0034] Specifically, a limiting block 28 is provided at the fixed end 22 to limit the extension and retraction of the telescopic end 21. The limiting block 28 is used to limit the extension and retraction.

[0035] Specifically, the stacking mechanism 4 includes a stepper motor 41, a transmission belt 42, a support frame 43, and a stacking bracket 44.
