Description

Technical Field

[0001] This utility model relates to the field of battery packaging technology, specifically to an automatic battery cell packaging production line. Background Technology

[0002] Traditional solar cell packaging production lines mostly employ semi-automatic or segmented automation methods, resulting in poor overall coordination and limited automation levels. While this approach can barely meet the demands of small-scale, standardized production, traditional solar cell packaging production lines are inadequate for large-scale, standardized production.

[0003] During the production of solar cells, they need to be sorted, packaged, and transported to a warehouse for storage. This process typically includes arranging, bagging, and handling the cells into the warehouse. Arranging the cells is usually done manually; workers manually stack multiple cells neatly, then bag them, pack them into cardboard or plastic boxes, and then manually move them to transfer carts. Finally, the cells are transported to the warehouse by hand.

[0004] However, the existing semi-automated production method that relies on manual operation is difficult to adapt to the needs of large-scale, high-speed production. Therefore, there is a need to provide an automated packaging production line. Utility Model Content

[0005] To overcome the above shortcomings, the purpose of this utility model is to provide an automated battery cell packaging production line that, through coordinated operation, automates the entire process of battery cell loading and packaging, significantly reducing manual intervention and improving overall production efficiency and capacity.

[0006] Technical solution: An automated packaging production line for solar cells, comprising: The feeding unit is used to transport battery cells; At least one aligning unit is provided, which is used to receive the battery cells conveyed by the feeding unit and to sort out and unload a plurality of stacked battery cells. A detection unit is used to detect the number of the assembled battery cells and whether there is any damage. A packaging unit, which is used to pack a number of qualified battery cells into a bag and package them. A transport unit for transporting a plurality of the packaged battery cells.

[0007] Furthermore, the feeding unit includes at least one feeding line, a feeding fixture, a paper-separating feeding mechanism, a conveying device, and a first transfer robot. The feeding line is used to transport the battery cells. The feeding fixture clamps the battery cells and places them on the conveying device. The conveying device transports the battery cells to the paper-separating feeding mechanism, which covers the battery cells with paper. The first transfer robot is used to transfer the battery cells covered with the paper to the lining unit.

[0008] Furthermore, the alignment unit includes an alignment platform, a blower mechanism, an alignment drive component, and a clamping component. The alignment platform is placed horizontally to receive several battery cells covered with the separator paper. The blower mechanism blows air in a direction parallel to the alignment platform. The clamping component acts on the upper surface of the battery cells to press the stacked battery cells together. The alignment drive component is used to push the sides of the stacked battery cells to make the battery cells neat and orderly.

[0009] Furthermore, the alignment platform also includes a first limiting part and a second limiting part. One side of the battery cell is attached to the first limiting part, and the other side adjacent to the first limiting part is attached to the second limiting part. The alignment platform also includes a rotating shaft, so that the alignment platform can rotate from a horizontal state to a vertical state, and the angle formed by the first limiting part and the second limiting part can be used to receive a number of battery cells.

[0010] Furthermore, the detection unit has at least four cameras for detecting several of the battery cells after they are aligned.

[0011] Furthermore, the packaging unit includes a second transfer robot, a bagging mechanism, and a pushing mechanism. The bagging mechanism and the pushing mechanism are connected via a bagging track. Several battery cells are placed on the bagging track from the detection unit via the second transfer robot. The bagging mechanism includes a bag suction cup and a spreading device. After the bagging mechanism opens and spreads the bag, the pushing mechanism is used to push several battery cells into the bag.

[0012] Furthermore, the packaging unit also includes a third transfer robot and a bag folding mechanism. The third transfer robot is used to transfer the bag containing the battery cells from the bagging mechanism to the bag folding mechanism.

[0013] Furthermore, the folding mechanism includes a folding plate and a flipping shaft. The folding plate is fixed on the flipping shaft, and the flipping shaft drives the folding plate to rotate, thereby causing the portion of the bag that extends beyond the battery cell to fold.

[0014] Furthermore, the production line also includes an NG module, which is used to recycle the battery cells that fail the inspection unit's test.

[0015] The beneficial effects of this utility model are as follows: (1) This utility model forms a continuous and efficient automatic packaging production line through multiple functional modules such as feeding unit, lining unit, detection unit, packaging unit and transportation unit, which significantly improves production efficiency, reduces manual intervention and realizes the production needs of large-scale and continuous production of battery cells; (2) The detection unit is equipped with multiple cameras to detect the number of battery cells and the surface damage in real time after the cells are arranged, so as to ensure that unqualified products are rejected before entering the packaging. In addition, an NG module is set up to recycle unqualified battery cells, thereby ensuring the quality of the packaged battery cells. (3) The alignment platform combines the blower mechanism and the alignment drive to achieve neat stacking of battery cells, which is convenient for subsequent packaging. The alignment platform can rotate from a horizontal state to a vertical state. The battery cells are supported by the first and second limiting parts. The weight of the battery cells makes each battery cell adhere to the first and second limiting parts, further improving the regularity of the battery cells. (4) The packaging unit uses a second transfer robot to accurately place the battery cells onto the bagging track. The bag is opened by the bag suction cup and the bag is opened by the stretching device. The pushing mechanism pushes the arranged battery cells into the bag, realizing high-speed and stable automatic bagging operation. At the same time, the bag folding mechanism folds the bag opening through the cooperation of the folding plate and the flipping shaft, which improves the automation level of the packaging process.

[0018] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The implementation methods of this utility model will now be described based on its overall structure.

[0020] like Figure 1 and Figure 2 As shown, this utility model discloses an automated packaging production line for battery cells, comprising: Feeding unit 2, which is used to transport battery cells 1; At least one aligning unit 3 is provided, which is used to receive the battery cells 1 conveyed by the feeding unit 2 and to sort out and unload a plurality of stacked battery cells 1. Detection unit 4 is used to detect the number of the assembled battery cells 1 and whether there is any damage; Packaging unit 5, the packaging unit 5 is used to put a number of qualified battery cells 1 into a bag and pack them; Transport unit 6, which is used to transport a plurality of packaged battery cells 1.

[0021] Using the above structure, the feeding unit 2 conveys the bulk solar cells 1 to the arranging unit 3. The arranging unit 3 arranges and stacks the conveyed solar cells 1 into neat groups. The inspection unit 4 inspects the arranged solar cells 1, identifying and removing those with incorrect quantities or damage, thus ensuring that the quality of the solar cells 1 entering subsequent processes meets the standards. The qualified solar cells 1 are automatically bagged and packaged by the packaging unit 5. Finally, the transport unit 6 transports the packaged solar cells 1 to the next process for collection or further processing. The automatic solar cell packaging production line of this invention can realize the transportation, sorting, inspection, packaging, and transport of solar cells 1 without manual intervention, significantly improving production efficiency and automation level, while ensuring the product quality and consistency of the solar cells 1, and has broad applicability.

[0022] Specifically, the feeding unit 2 includes at least one feeding line 21, a feeding fixture 22, a paper-separating feeding mechanism 23, a conveying device 24, and a first transfer robot 25. The feeding line 21 transports the battery cells 1 to the feeding position in an orderly manner. The feeding fixture 22 picks up the transported battery cells 1 and places them on the conveying device 24. The conveying device 24 transports the battery cells 1 to the paper-separating feeding mechanism 23, which covers the battery cells 1 with paper to protect them from contact or friction, thus preventing scratches or damage to the surface of the battery cells 1. The battery cells 1, now covered with paper, are then transferred by the first transfer robot 25 to the lining unit 3. Through this structure, the feeding of the battery cells 1 achieves fully automated operation from conveying, gripping, paper separation, to transfer, effectively reducing manual intervention and improving the continuity and stability of the feeding process.

[0023] Furthermore, such as Figure 3 As shown, the aligning unit 3 includes an aligning platform 31, a blower mechanism 32, an aligning drive component 33, and a clamping component 34. The aligning platform 31 is horizontally positioned to receive several battery cells 1 covered with separator paper transferred from the feeding unit 2. The aligning platform 31 serves as the reference surface for the aligning operation. The blower mechanism 32 is located on the side of the aligning platform 31 and blows air towards the side of the battery cells 1 in a direction parallel to the aligning platform 31, thereby preventing the battery cells 1 from sticking together. It also plays a role in fine-tuning the position of the battery cells 1 and assisting in the aligning. The clamping component 34 is located above the aligning platform 31 and is used to apply vertical pressure from top to bottom to the stacked battery cells 1, ensuring that the stacked battery cells 1 remain flat and in close contact. The aligning drive component 33 is located on the side of the aligning platform 31 and is used to laterally push different sides of the battery cells 1, further aligning them neatly under the clamping state to form a group of battery cells 1 with neat edges and uniform stacking.

[0024] Specifically, the aligning platform 31 also includes a first limiting part 311 and a second limiting part 312, used to limit two adjacent sides of the battery cell 1, thereby ensuring that the battery cell 1 maintains precise positioning during stacking and avoiding lateral or longitudinal slippage. One side of the battery cell 1 is attached to the first limiting part 311, and the other adjacent side is attached to the second limiting part 312, positioning the battery cell 1 on the aligning platform 31 through a two-point limiting method. Preferably, the aligning platform 31 also has a rotating shaft 313, so that the aligning platform 31 can rotate from a horizontal state to a vertical state. When the alignment platform 31 is in a horizontal state, the battery cells 1 are supported on the alignment platform 31. When the battery cells 1 are stacked to a preset number, the alignment platform 31 rotates to a vertical state. The angle formed between the first limiting part 311 and the second limiting part 312 can form a "V"-shaped structure, thereby effectively receiving and guiding several battery cells 1 to automatically fall between the first limiting part 311 and the second limiting part 312 under the action of gravity, improving the compactness and consistency of the alignment. Through the cooperation of the first limiting part 311 and the second limiting part 312, the battery cells 1 are physically limited in two directions, improving the neatness and positioning accuracy of the stacked battery cells 1.

[0025] Furthermore, the detection unit 4 is equipped with at least four cameras 41. The assembled battery cells 1 are transferred to the detection unit 4 for inspection. The stacked battery cells 1 are placed on the detection platform, and at least four cameras 41 are arranged around the detection platform at different angles to perform multi-angle, all-round image acquisition and recognition of the assembled battery cells 1. Through the recognition by the camera array 41, the quantity, arrangement, and presence of defects such as damage, missing corners, and fragments of the battery cells 1 can be accurately detected, ensuring that all battery cells 1 entering the packaging stage are qualified products.

[0026] Furthermore, the packaging unit 5 includes a second transfer robot 51, a bagging mechanism 52, and a pushing mechanism 53. The bagging mechanism 52 and the pushing mechanism 53 are connected via a bagging track 54, forming a continuous packaging process. The second transfer robot 51 receives several battery cells 1 from the detection unit 4 and places them on the bagging track 54, providing an accurate positioning basis for subsequent bagging operations. The bagging mechanism 52 includes a bagging suction cup 521 and an opening device 522. The bagging suction cup 521 picks up a pre-made bag and vacuum-adheres it to open it. The opening device 522 extends into the bag after the suction cup has positioned the opening and opens it to a fully open state, facilitating the smooth insertion of the battery cells 1. After the battery cells 1 are placed on the bagging track 54, the pushing mechanism 53 pushes them from the bagging track 54 into the opened bag, completing the bagging operation. In one feasible embodiment, the opening device 522 can be a cylinder-controlled lever, which, after being inserted into the bag, opens the bag to both sides, thereby ensuring that the battery cell 1 can be smoothly pushed into the bag. Through the above mechanism, the bag suction cup 521 of the bagging mechanism 52 and the opening device 522 work together to automatically complete the gripping, opening, and opening of the bag, avoiding manual intervention and improving bagging efficiency. The pushing mechanism 53 can be controlled by a cylinder, thereby ensuring that the battery cell 1 enters the bag stably and smoothly, avoiding tipping, jamming, or damage to the battery cell 1. The bagging process of the battery cell 1 is continuous, efficient, and highly automated, which not only significantly improves production efficiency but also reduces the uncertainty and defects that may be caused by human operation, ensuring that each group of battery cells 1 is packaged neatly and consistently.

[0027] Furthermore, the packaging unit 5 also includes a third transfer robot 55 and a bag-folding mechanism 56, used to fold the bagged battery cells 1 after they have been filled. Specifically, the third transfer robot 55 is positioned between the bagging mechanism 52 and the bag-folding mechanism 56, used to transfer the bag containing the battery cells 1 from the bagging track 54 to the working platform of the bag-folding mechanism 56. The third transfer robot 55 can adopt a multi-axis linkage structure, thereby achieving precise gripping, stable handling, and smooth release of the bag, providing a stable posture and accurate position for subsequent bag-folding processing. Figure 4 As shown, the folding mechanism 56 includes a folding plate 562 and a flipping shaft 561, used to fold the bag portion extending beyond the edge of the battery cell 1. One end of the folding plate 562 is fixedly connected to the flipping shaft 561, which can rotate around its own axis under the action of a driving device. Preferably, the driving device can be a servo motor. When the bagged battery cell 1 is delivered to the folding mechanism 56 and positioned, the folding plate 562 extends into the bag, and the flipping shaft 561 drives the folding plate 562 to rotate. The folding plate 562 rotates from its initial position along the axis of the flipping shaft 561, pushing the upper edge of the bag and folding it over, thereby folding the bag portion extending beyond the battery cell 1 backward to the top of the battery cell 1, forming a neat folded edge.

[0028] Furthermore, the production line also includes an NG module 7, used for the automatic recycling of defective battery cells 1 identified by the detection unit 4, preventing defective products from flowing into the subsequent packaging process, thereby ensuring the overall quality of the battery cells 1. Specifically, the NG module 7 is located downstream of the detection unit 4. When the detection unit 4 identifies a defect in a group or a single battery cell 1 through image recognition, quantity counting, damage judgment, etc., such as damage, missing corners, irregular shapes, misalignment, or insufficient quantity, the detection unit 4 immediately sends an NG signal to the central control system. The control system then instructs the NG module 7 to start the sorting process. The second transfer robot 51 picks up the defective battery cells 1 and places them in the NG module 7 for recycling. The NG module 7 can collect the defective battery cells 1 via guide rails for temporary storage, facilitating subsequent manual centralized inspection, rework, or scrapping. The NG module 7 achieves automatic diversion and recycling of defective products, avoiding the lag and misjudgment of manual picking, while maintaining the continuity and efficiency of the production process.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
