[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a feeding structure for a battery cell backing double-sided adhesive tape machine. Background Technology

[0002] With the rapid development of new energy vehicles, consumer electronics, and energy storage industries, the demand for lithium-ion battery cells is increasing daily, placing higher demands on the precision, efficiency, and reliability of their manufacturing processes. In the subsequent module assembly process of battery cells, it is often necessary to attach double-sided tape to their backs for fixing, heat conduction, or insulation. The battery cell double-sided tape attaching machine is a dedicated automated equipment that completes this process. Existing equipment uses pneumatic or servo-driven grippers to directly grip and transport battery cells. Although this method is simple in structure, it has obvious drawbacks: the grippers are in hard contact with the surface of the battery cell, which can easily cause indentations or even scratches on the smooth aluminum-plastic film or metal shell surface of the battery cell, seriously affecting the product's appearance and quality, resulting in a low yield rate. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a feeding structure for a battery cell backing double-sided adhesive tape machine, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a feeding structure for a battery cell double-sided adhesive applicator, characterized in that it includes a frame, a feeding conveyor line set on the frame, and a robot arm that can transport the battery cell from the feeding position to the adhesive applicator position. The execution end of the robot arm is provided with a suction cup assembly, which includes a non-contact Bernoulli suction cup for avoiding damage to the surface of the battery cell.

[0005] As a further technical solution of this utility model, the suction cup assembly includes a mounting plate, and at least one Bernoulli suction cup is disposed on the mounting plate.

[0006] As a further technical solution of this utility model, the mounting plate is also provided with at least one flexible contact sponge suction cup, and the Bernoulli suction cup and the sponge suction cup cooperate with each other to pick up the battery cell.

[0007] As a further technical solution of this utility model, there are two Bernoulli suction cups, which are located at opposite corners of the mounting plate; there are also two sponge suction cups, which are distributed at the other two opposite corners of the mounting plate.

[0008] As a further technical solution of this utility model, a leveling mechanism is provided between the mounting plate and the end effector of the robot arm, and the leveling mechanism is a floating joint or a flexible cylinder.

[0009] As a further technical solution of this utility model, a fiber optic sensor or visual detector for detecting whether the battery cell has been successfully picked up is also provided on one side of the suction cup assembly.

[0010] As a further technical solution of this utility model, the Bernoulli suction cup is connected to a vacuum circuit system, and the vacuum circuit system is equipped with a precision pressure regulating valve for adjusting the adsorption pressure and a pressure sensor for detecting the vacuum degree.

[0011] As a further technical solution of this utility model, the feeding conveyor line is a belt conveyor line, a roller conveyor line, or a flexible vibrating plate.

[0012] This utility model provides a feeding structure for a battery cell backing double-sided tape application machine, which has the following advantages compared with the prior art: 1. The feeding structure for a battery cell backing double-sided tape attaching machine designed in this paper adopts a non-contact Bernoulli suction cup as the core picking component, which utilizes its unique hydrodynamic properties to generate adsorption force. Compared with the existing technology, it avoids physical contact with the battery cell surface, fundamentally eliminating the surface scratches, indentations and contamination problems that may be caused by traditional suction cups or mechanical grippers, and significantly improving the product yield. 2.

The feeding structure for a battery cell backing double-sided tape applicator designed in this paper equips the Bernoulli suction cup with an intelligent air circuit system that includes a precision pressure regulating valve and a pressure sensor, and integrates a high-sensitivity detection sensor.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a feeding structure technical solution for a battery cell backing double-sided tape application machine: like Figure 1 As shown, the device includes a frame 1, a feeding conveyor line 2 mounted on the frame 1, and a robotic arm 3 that can transport the battery cell 100 from the feeding position to the adhesive application position. The robotic arm 3 has a suction cup assembly 4 at its end. The suction cup assembly 4 includes a non-contact Bernoulli suction cup 41 to avoid damaging the surface of the battery cell 100. The Bernoulli suction cup 41 generates a high-speed airflow through compressed air, creating a low-pressure zone between the suction cup and the surface of the battery cell 100 according to Bernoulli's principle, thus generating an adsorption force. During operation, it maintains a gap of 0.1–0.5 mm with the surface of the battery cell 100, achieving non-contact gripping, avoiding physical contact between the traditional suction cup and the surface of the battery cell 100, reducing surface damage such as scratches and indentations, and improving product yield.

[0017] like Figure 2 As shown, the suction cup assembly 4 includes a mounting plate 42, on which at least one Bernoulli suction cup 41 is disposed; the mounting plate 42 provides support and positioning for the suction cups, keeping each suction cup on the same plane, improving the structural stability and installation accuracy of the suction cup assembly 4, and providing a foundation for stable gripping.

[0018] like Figure 1 and Figure 2As shown, at least one flexible contact sponge suction cup 43 is also provided on the mounting plate 42. The Bernoulli suction cup 41 and the sponge suction cup 43 cooperate with each other to pick up the battery cell 100. The Bernoulli suction cup 41 provides the main suction force, and the sponge suction cup 43 provides auxiliary stability and buffering during the movement, maintaining the advantages of non-contact gripping, while improving the stability and placement accuracy of the handling process.

[0019] like Figure 2 As shown, there are two Bernoulli suction cups 41, located at opposite corners of the mounting plate 42; there are two sponge suction cups 43, distributed at the other two opposite corners of the mounting plate 42; the diagonal arrangement makes the adsorption force evenly distributed, and the four suction cups together form a support system, reducing the tilting or shaking of the battery cell 100 during transportation and improving the stability of the transportation process.

[0020] like Figure 3 As shown, a leveling mechanism 5 is provided between the mounting plate 42 and the execution end of the robot arm 3. The leveling mechanism 5 is a floating joint or a flexible cylinder. The leveling mechanism 5 allows the suction cup assembly 4 to make small angle adaptive adjustments to keep it parallel to the surface of the battery cell 100, promote the uniform distribution of the Bernoulli air film, improve the adsorption force, and reduce the risk of edge collision.

[0021] like Figure 3 As shown, a fiber optic sensor or vision detector 6 is also provided on one side of the suction cup assembly 4 to detect whether the battery cell 100 has been successfully picked up; the sensor detects whether there is a battery cell 100 at the suction cup position and feeds the signal back to the control system to monitor the gripping status, detect any missed or detached abnormalities in a timely manner, and improve production reliability.

[0022] like Figure 3 As shown, the Bernoulli suction cup 41 is connected to a vacuum circuit system, which is equipped with a precision pressure regulating valve 7 for adjusting the adsorption pressure and a pressure sensor 8 for detecting the vacuum level. The pressure sensor 8 monitors the adsorption vacuum level and adjusts the air intake pressure through the precision pressure regulating valve 7 to maintain the adsorption force, thereby controlling and maintaining the adsorption force and adapting to the gripping needs of different specifications of battery cells 100.

[0023] like Figure 1 As shown, the feeding conveyor line 2 is a belt conveyor line, roller conveyor line or flexible vibrating plate; the type of conveyor line is selected according to different production needs to transport the battery cells 100 to the feeding station, improve the flexibility of the connection between the equipment and the previous process, and enhance the coordination of the production line.

[0024] The working principle of this invention is as follows: When the system receives a loading command, the vacuum circuit system is activated. Compressed air is precisely regulated by the precision pressure regulating valve 7 and delivered to the non-contact Bernoulli suction cup 41 at a predetermined pressure and flow rate. The pressure sensor 8 monitors the air circuit pressure in real time to ensure stable air supply parameters. The robotic arm 3 moves the suction cup assembly 4 to the loading station. The high-speed airflow ejected from the Bernoulli suction cup 41 forms a low-pressure area below it. According to Bernoulli's principle, a pressure difference is generated between this low-pressure area and the surrounding atmospheric pressure, thereby forming an upward suction force. During this process, the suction cup maintains a stable micro-gap of 0.1-0.5mm between itself and the surface of the battery cell 100, achieving non-contact gripping. During the adsorption process, the flexible contact sponge suction cup 43 works in conjunction with the Bernoulli suction cup 41. The Bernoulli suction cup 41 provides the main adsorption force, while the sponge suction cup 43 plays an auxiliary stabilizing and buffering role. The leveling mechanism 5 automatically adjusts the posture of the suction cup assembly 4 to keep it parallel to the surface of the battery cell 100, ensuring uniform distribution of the adsorption force. A fiber optic sensor or vision detector 6 monitors the grasping status in real time to confirm whether the battery cell 100 has been successfully picked up. The vacuum air path system continuously monitors the adsorption status through the pressure sensor 8 and dynamically adjusts the airflow parameters through the precision pressure regulating valve 7 to adapt to the grasping requirements of different specifications of battery cells 100. The robotic arm 3 smoothly transports the battery cell 100 to the adhesive application station. During placement, the sponge suction cup 43 contacts the work platform before the Bernoulli suction cup 41, providing a cushioning effect to ensure that the battery cell 100 is gently and accurately placed in place.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
