Description

Technical Field

[0001] The invention relates to a feeding process and system of a cell passivation machine, belonging to the technical field of solar cell production. Background Art

[0002] In the photovoltaic industry, the processing of the cut surface of the cell is a crucial link. The cut surface of the cell is repaired by coating with a passivation machine, thereby achieving the purpose of improving the power generation rate of the cell.

[0003] However, in the cell passivation process, efficient, accurate and stable feeding technology and equipment are the key to ensure the smoothness of the entire production process and stable product quality. Cells need to be shaped before entering the passivation machine. Traditional feeding methods have problems such as inaccurate positioning, slow feeding speed, and damage to the cells. This not only affects production efficiency, but also causes irreversible damage to the cells, reducing the yield rate.

[0004] Therefore, this application aims to develop an efficient, intelligent, and low-damage cell passivation machine loading process and equipment, which can achieve precise positioning, rapid grasping and placement of cell cells, while ensuring that no physical damage is caused to the cell cells during the entire loading process, so as to meet the photovoltaic industry's demand for efficient and high-quality production and promote technological progress and industrial upgrading in the photovoltaic industry. Summary of the invention

[0005] In view of the above deficiencies in the prior art, the present invention provides a feeding process and system for a battery cell passivation machine that can achieve efficient, safe and damage-free feeding of battery cells by optimizing the feeding process and improving the accuracy and intelligence level of the equipment.

[0006] The feeding process of the cell passivation machine of the present invention comprises the following steps:

[0007] S1. After the battery cells arrive, pick up a single battery cell and align and stack it on the pallet of the alignment station;

[0008] S2. When the stacking reaches the set number, the pallet and the entire stack of cells are placed into the passivation carrier;

[0009] S3, sending the passivation carrier into the passivation machine;

[0010] S4, after the passivation is completed and the battery cells are removed, the loading system receives the passivation carrier with the pallet;

[0011] S5. Take out the pallet in the passivation carrier and place it in the alignment station, and the passivation carrier waits for filling.

[0012] Steps S1 to S5 are repeated repeatedly.

[0013] The pallet is used to support the battery cells and serves as a platform for stacking the battery cells.

[0014] In the step S1, after the battery cells are received, the positions and angles of the single battery cells are first corrected at the correction station, so that the positions and angles of all the single battery cells are consistent when they are picked up, which is convenient for the subsequent picking and stacking.

[0015] In step S2, the front of the passivation carrier is opened, and the pallet and the whole stack of battery cells are placed horizontally into the passivation carrier through the front opening. In addition, the top surface of the passivation carrier is also provided with an opening, and the opening of the top surface is provided with an upper cover. After the upper cover is opened, the pallet and the battery cells are placed from the front, and the upper cover is closed after the placement is completed.

[0016] In step S3, after the battery cell is placed in, the passivation carrier is turned 90 degrees so that the front opening of the box body faces upward, so that the cut surface of the battery cell faces upward, and then the passivation carrier is sent into the passivation machine to facilitate the subsequent cooperation with the passivation machine to passivate the side walls of the battery cell.

[0017] During the process, the battery cells are transported in a horizontal state, and the transport robot can stabilize the entire stack of battery cells by applying a small force to prevent them from being damaged by clamping (a larger clamping force is required when the entire stack of battery cells is in a vertical state).

[0018] A feeding system for a battery cell passivation machine, comprising:

[0019] Suction cup gripping mobile module for picking up and transporting single battery cells;

[0020] A tray for supporting the battery cells;

[0021] An alignment device for stacking and aligning the stack of cells;

[0022] A handling device for carrying pallets and stacks of cells;

[0023] Passivation carriers for loading pallets and stacks of cells;

[0024] A fully loaded carrier transfer line for feeding the passivation carriers into the passivation machine;

[0025] The suction cup grabbing mobile module can pick up a single battery cell and transport it to the pallet of the alignment device for stacking. The alignment device can stack the entire stack of battery cells neatly. The handling device can send the pallet and the entire stack of battery cells into the passivation carrier. The fully loaded carrier transmission line can send the passivation carrier loaded with battery cells into the passivation machine.

[0026] Wherein, the alignment device includes a sorting box for holding battery cells. The sorting box can be tilted so that the battery cells in the box can be aligned with their long and short sides after sliding. The side of the sorting box is also provided with a wind knife that can blow air into the sorting box to promote the alignment of the battery cells in the box. The relative height of the wind knife and the sorting box is adjustable so that the air outlet of the wind knife always acts on the top battery cell area that has just been stacked; the wind knife can output airflow into the gap between the battery cells, assist the battery cells to slide in the regular box, and can also provide the thrust required for the alignment of the battery cells. The side of the sorting box is also provided with a detection device for monitoring whether the battery cells are neatly stacked. When the battery cells are not neatly aligned under the tilting effect of the sorting box and the boosting effect of the wind knife, the detection device feeds back a signal to the long side regularization mechanism and / or the short side regularization mechanism, and the long and short sides of the stacked battery cells are aligned through thrust.

[0027] The passivation carrier described in the present invention includes a box body with openings on the front and top surfaces, and an openable and closable upper cover is provided on the top of the box body. The upper cover is fixed by claws with self-resetting (self-locking) functions on both sides of the top of the box body. When the upper cover is closed, the support plate and the entire stack of battery cells in the box body can be pressed and fixed.

[0028] The present invention also includes a cover opening and closing mechanism, which includes a claw that can push the claws to both sides, and also includes a cover lifting module that can grab the cover and drive it to rise and fall. After the claw pushes the claws of the passivation carrier to both sides, the cover lifting module can drive the cover to detach from the top of the box body; after the support plate and the whole stack of battery cells are placed in the box body, the cover lifting module drives the cover to fall, the claw is reset to the middle and the claw locks the cover.

[0029] The present invention also includes a flipping mechanism that can flip the passivation carrier 90 degrees so that the front opening of the box body faces upward, and the flipping mechanism includes an L-shaped placement seat for placing the passivation carrier. The manipulator transports the passivation carrier to the L-shaped placement seat, and the L-shaped placement seat is driven by a flipping motor to complete the flipping action to realize the flipping of the passivation carrier. The flipped passivation carrier is sent to the passivation machine through the fully loaded carrier transmission line.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. High efficiency: By optimizing the loading process, the rapid picking, stacking, alignment and feeding of battery cells are realized, which greatly improves the production efficiency. The use of automated and intelligent equipment and systems realizes real-time monitoring and feedback of the position and status of battery cells, reduces manual intervention, improves the automation level of the entire production line, and improves the intelligence level of the production process.

[0032] 2. Safety and low damage: The battery cells are supported by a pallet, which effectively prevents damage to the battery cells in subsequent processes. During the transportation process, the battery cells are in a horizontal state, which reduces the force required by the handling manipulator and prevents the battery cells from being clamped or dropped. The passivation carrier ensures the stability of the battery cells during the transmission and passivation process.

[0033] 3. Improve the yield rate: reduce the damage of the cell during the loading process, improve the accuracy and efficiency of the passivation treatment, and significantly improve the yield rate and product quality of the cell. The implementation of the present invention not only meets the photovoltaic industry's demand for efficient and high-quality production, but also promotes the technological progress and industrial upgrading of the photovoltaic industry, and provides strong support for the sustainable development of the industry.
