Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a liquid injection sealing glue nail feeding system. Background Technology

[0002] During the production of lithium-ion batteries, electrolyte needs to be injected two or more times. After the electrolyte injection is completed, a sealing nail needs to be inserted into the injection hole of the battery to seal the injection hole and prevent the injected electrolyte from flowing out.

[0003] In existing technology, after a mechanical gripper picks up a sealing nail from a vibratory feeder, it moves to the battery's electrolyte filling hole and inserts the sealing nail. During operation, the gripper easily comes into contact with the electrolyte on the battery surface, causing corrosion damage. Furthermore, the electrolyte on the gripper directly contacts the sealing nail in the vibratory feeder, leading to contamination and adhesion of the nail, or the nail falling off during movement, resulting in wasted sealing nails or improper insertion. Utility Model Content

[0004] In view of this, the present invention provides a liquid-filled sealing nail feeding system, which avoids the electrolyte contamination of the sealing nails in the vibratory plate and solves the problem of sealing nails sticking and falling off due to electrolyte contamination.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A liquid-filled sealant nail feeding system is provided for conveying sealant nails to a nailing station in a battery. The system includes a vibratory feeder, a first robotic arm, a transfer station for nailing, and a second robotic arm. The transfer station for nailing is positioned between the first and second robotic arms. The vibratory feeder contains multiple sealant nails. The first robotic arm, positioned between the vibratory feeder and the transfer station for nailing, transfers the sealant nails from the transfer station to the nailing station. The second robotic arm, positioned between the transfer station for nailing and the nailing station, transfers the sealant nails from the transfer station for nailing to the nailing platform at the nailing station.

[0007] As can be seen from the above technical solution, the liquid-filled sealing nail feeding system provided by this utility model, by setting up a transfer nail preparation platform, a first robotic arm, and a second robotic arm, allows the first robotic arm to transfer the sealing nails in the vibratory feeder to the transfer nail preparation platform, while the second robotic arm transfers the sealing nails on the transfer nail preparation platform to the battery at the nailing station. By adding a transfer nail preparation platform and a transfer robotic arm, the second robotic arm, which is in direct contact with the battery, does not need to contact the vibratory feeder. Therefore, even if the second robotic arm gets contaminated with electrolyte during the nailing process, it will not contaminate other sealing nails in the vibratory feeder. This effectively prevents the robotic arm from leaving electrolyte when picking up sealing nails from the vibratory feeder, avoiding electrolyte contamination of the sealing nails in the vibratory feeder, and thus solving the problem of sealing nail adhesion and falling off caused by electrolyte contamination.

[0042] This utility model discloses a liquid-injected sealing nail feeding system, which avoids electrolyte contamination of the sealing nails in the vibratory feeder and solves the problem of sealing nails sticking and falling off due to electrolyte contamination.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] A single battery cell can store chemical energy and controllably convert it into electrical energy. In recyclable battery cells, the active materials can be reactivated through charging after discharge, allowing for continued use. As the smallest unit of a battery system, a single battery cell mainly consists of five core components: the positive electrode, the negative electrode, the electrolyte, the separator, and the casing. The electrolyte is a crucial component inside the battery, playing a vital role in the charging and discharging process. It not only handles ion transport but also participates in electrochemical reactions, ensuring the battery functions properly.

[0045] See Figures 1 to 17 This utility model discloses a liquid-filled sealing nail feeding system for conveying sealing nails 8 to the nailing station of a battery 6. The system includes a vibratory feeder 2, a first robotic arm 4, a transfer nail preparation platform 3, and a second robotic arm 5. The transfer nail preparation platform 3 is positioned between the first robotic arm 4 and the second robotic arm 5. The vibratory feeder 2 contains multiple sealing nails 8. The first robotic arm 4, positioned between the vibratory feeder 2 and the transfer nail preparation platform 3, transfers the sealing nails 8 from the vibratory feeder 2 to the transfer nail preparation platform 7. The second robotic arm 5, positioned between the transfer nail preparation platform 3 and the nailing station, transfers the sealing nails 8 from the transfer nail preparation platform 3 to the nailing table 7 of the nailing station.

[0046] The vibratory plate 2 vibrates to make the sealing nails 8 inside the plate into an upright position, that is, the nail head 801 facing upwards. The first robot arm 4 transfers the sealing nails 8 in the upright position to the transfer nail preparation table 3. The sealing nails 8 on the transfer nail preparation table 3 are then transferred to the top of the battery 6 by the second robot arm 5, and then the sealing nails 8 are driven into the liquid injection hole 601 on the battery 6.

[0047] This utility model discloses a liquid-filled sealant nail feeding system. It includes a transfer nail preparation platform 3, a first robotic arm 4, and a second robotic arm 5. The first robotic arm 4 transfers the sealant nails 8 from the vibratory feeder 2 to the transfer nail preparation platform 3, while the second robotic arm 5 transfers the sealant nails 8 from the transfer nail preparation platform 3 to the battery 6 at the nailing station. By adding a transfer nail preparation platform 3 and a transfer robotic arm, the second robotic arm 5, which is in direct contact with the battery 6, does not need to contact the vibratory feeder 2. Therefore, even if the second robotic arm 5 becomes contaminated with electrolyte during nailing, it will not contaminate other sealant nails 8 in the vibratory feeder 2. This effectively prevents electrolyte residue when the robotic arm picks up the sealant nails 8 from the vibratory feeder 2, avoiding electrolyte contamination of the sealant nails 8 in the vibratory feeder 2, and thus solving the problem of sealant nails sticking and falling off due to electrolyte contamination.

[0048] To broaden the applicability of the first robotic arm 4, it is a vacuum suction cup robotic arm. The first robotic arm 4 includes a main pipeline 401 and a vacuum suction port 402, as follows: Figure 4 As shown, the main pipeline 401 is connected to a vacuum system, which is a commonly used device in the prior art and will not be described in detail here. The cavity of the main pipeline 401 is connected to a vacuum suction port 402, which is used to suck up the sealing nails 8 inside the vibratory plate 2.

[0049] To facilitate adjustment of the clamping force when the sealing nail 8 is inserted into the injection hole 601, the second robotic arm 5 is a gripper robotic arm. Specifically, the second robotic arm 5 includes a pusher rod 502 and a gripper 501, as shown below. Figure 5 As shown, the gripper 501 is used to grip the sealing nail 8. The structure and drive structure of the gripper 501 are existing technologies. To prevent electrolyte from contaminating the gripper 501, the second robotic arm 5 is also equipped with a nail pusher 502, which is coaxially arranged with the center of the gripper 501, as shown... Figure 5 As shown, the push rod 502 is disposed at the nail head 801 end of the sealant nail 8 on the gripper 501. The push rod 502 moves along its axis under the drive of the drive device, and the direction of movement is as shown in the figure. Figure 5The arrow in the diagram indicates the direction of the sealant nail 8. When it is necessary to insert the sealant nail 8 held by the gripper 501 into the injection hole 601, the clamping force of the gripper 501 is reduced to the set value. At this time, the gripper 501 uses only a small clamping force to limit the sealant nail 8, and controls the drive device to drive the push rod 502 to move downward until the sealant nail 8 is inserted into the injection hole 601.

[0050] Furthermore, the driving device can be a pneumatic cylinder or an electric cylinder, or other linear drive devices commonly used by those skilled in the art, and is not limited here.

[0051] In this design, a battery 6 is placed on the nailing platform 7. When the gripper 501 moves to the position where the sealing nail 8 it holds corresponds to the injection hole 601 on the battery 6, the distance between the gripper 501 and the surface of the battery 6 furthest from the nailing platform 7 is D1mm, and the total length of the sealing nail 8 is D2mm. The range of D1-D2 is 15.5-27.5mm, specifically any value among 15.5mm, 18mm, 21.5mm, 25mm, and 27.5mm, or any value between any two values. By setting the range of D1-D2 within the above range, it is convenient to drive the sealing nail 8 into the injection hole 601, and at the same time, it is convenient for the gripper 501 to hold the sealing nail 8 and move it smoothly above the injection hole 601. If the values ​​of D1 and D2 are too large, the initial position of the sealing nail 8 will be too far from the injection hole 601. When the sealing nail 8 is driven into the injection hole 601 by the push rod 502, it is prone to tilting, reducing the efficiency of driving the nail in. If the values ​​of D1 and D2 are too small, the sealing nail 8 may easily interfere with other structures on the battery 6 (such as terminals) during its movement above the injection hole 601. Furthermore, the range of D1mm is 20-30mm, specifically any value of 20mm, 22mm, 25mm, 28mm, or 30mm, or a value between any two of these values. The range of D2mm is 2.5-4.5mm, specifically any value of 2.5mm, 3mm, 3.5mm, 4mm, or 4.5mm, or a value between any two of these values.

[0052] To ensure that the sealant nails 8 on the transfer nail preparation table 3 remain in the correct nail position, the transfer nail preparation table 3 includes a table surface 301, on which at least one first limiting hole 302 for placing the sealant nails 8 is provided. Figures 7 to 9 The first limiting hole 302 is correspondingly set with the sealing nail 8. This corresponding setting includes not only corresponding position and the same quantity, but also that the size and shape of the sealing nail 8 inserted into the first limiting hole 302 are the same as those of the first limiting hole 302. For example... Figure 10 The diagram shown is a structural schematic of the sealant nail 8 after it is inserted into the first limiting hole 302.

[0053] To facilitate the placement of the sealing nail 8 within the first limiting hole 302, the hole axis of the first limiting hole 302 is set perpendicular to the platform 301. One or more first limiting holes 302 can be provided; this is not limited here.

[0054] In one embodiment, a plurality of first limiting holes 302 are provided on the platform 301 along the length direction of the platform 301. Correspondingly, a plurality of first gripping parts are provided on the first robotic arm 4 along a straight line. The number of first limiting holes 302 is the same as the number of first gripping parts, and their arrangement spacing and position are corresponding, so that the first gripping parts and the first limiting holes 302 are arranged in a one-to-one correspondence, so that when all the first gripping parts of the first robotic arm 4 have gripped the sealing nails 8, there are a sufficient number of first limiting holes 302 on the platform 301 to place the sealing nails 8. In one embodiment, four first limiting holes 302 are provided on the platform 301, and the four first limiting holes 302 are evenly distributed along the length direction of the platform 301, such as... Figure 8 and Figure 9 As shown.

[0055] To prevent air in the first limiting hole 302 from affecting the insertion of the sealing nail 8, a vent 303 is provided on the side of the transfer nail preparation platform 3. The vent 303 is connected to the first limiting hole 302, so that when the sealing nail 8 is inserted into the first limiting hole 302, the air in the first limiting hole 302 is discharged along the vent 303, which facilitates the smooth insertion of the sealing nail 8 into the first limiting hole 302.

[0056] The sealant nail 8 includes a nail head 801 and a nail body 802, such as... Figure 11 As shown. Preferably, the nail head 801 and the nail body 802 are an integral structure. Specifically, the sealant nail 8 has a cylindrical structure, and the diameter of the nail head 801 is larger than the diameter of the nail body 802. The nail body 802 includes a stepped sealing section 8021 and a tail section 8022. The diameter of the sealing section 8021 is larger than the diameter of the tail section 8022, and the tail section 8022 is located at the end of the sealing section 8021 away from the nail head 801. By setting the diameter of the tail section 8022 to the thinnest section on the sealant nail 8, it is easier for the sealant nail 8 to be inserted into the first limiting hole 302 or the injection hole 601. To improve the stability of the sealant nail 8 placed on the first limiting hole 302, such as... Figure 10 As shown, the first limiting hole 302 is a stepped hole, and the tail section 8022 of the sealing nail 8 and part of the sealing section 8021 are placed in the first limiting hole 302.

[0057] Specifically, the vibratory feeder 2 includes a main body 201 and a limiting plate 202 connected to the main body 201, such as... Figures 12 to 14As shown, the limiting plate 202 is provided with a plurality of second limiting holes 2021 arranged in a row. The disk body 201 is connected to the vibration platform, which is an electromagnetic vibration platform. When the electromagnetic vibration platform vibrates, it drives the vibrating disk 2 and the sealing nails 8 inside it to vibrate. Part of the nail body 802 of the sealing nail 8 enters into the second limiting hole 2021, so that the sealing nail 8 is in a positive nail posture. Further, the diameter of the second limiting hole 2021 is larger than the diameter of the tail section 8022 and smaller than the diameter of the sealing section 8021. When the sealing nail 8 is inserted into the second limiting hole 2021, it is the tail section 8022 that is inserted into the second limiting hole 2021. Figure 15 As shown. To facilitate the identification of the posture of the sealing nails 8 within the vibratory feeder 2, the liquid-filled sealing nail feeding system of this invention also includes a first detection device (not shown in the figure). The first detection device is positioned above the vibratory feeder 2, and its specific location and height are such that its field of vision can cover the entire limiting plate 202. Using an electromagnetic vibration platform, intermittent vibration can be achieved, resulting in lower energy consumption compared to the vibratory discs in the prior art that require continuous vibration.

[0058] To accommodate different models of sealing nails 8, the limiting plate 202 is detachably connected to the disc body 201. By replacing different limiting plates 202, the limiting requirements of different sealing nails 8 can be met. The diameter and hole spacing of the second limiting hole 2021 on the limiting plate 202 are different for different models of sealing nails 8.

[0059] In one specific embodiment, a first connecting hole 2012 is provided on the disk body 201, and the first connecting hole 2012 is disposed on the support ring platform 2011, such as... Figure 17 As shown. A second connecting hole 2022 is provided on the limiting plate 202 at a position corresponding to the first connecting hole 2012, as shown. Figure 16 As shown, the limiting plate 202 and the disk body 201 are connected by a connector that is connected within the first connecting hole 2012 and the second connecting hole 2022. This structural connection enables a detachable connection between the limiting plate 202 and the disk body 201. It can be understood that the first connecting hole 2012 is a threaded hole, the second connecting hole 2022 is a through hole, and the connector is a connecting screw or a connecting bolt, which passes through the second connecting hole 2022 and is threaded into the first connecting hole 2012.

[0060] In another embodiment, the limiting plate 202 and the disk body 201 are connected by a snap-fit ​​detachable connection. That is, one of the limiting plate 202 and the disk body 201 is provided with a slot, and the other is provided with a buckle, with the slot and buckle corresponding to each other. Specifically, a buckle is provided on the surface of the limiting plate 202 that contacts the disk body 201, and a slot is provided on the disk body 201 at a position corresponding to the buckle, with the buckle snapping into the slot.

[0061] To facilitate the automatic supply of sealing nails 8 to the vibratory feeder 2, the liquid-filled sealing nail feeding system of this utility model also includes a nail hopper 1. For automatic nail supply, the nail hopper 1 is mounted on the vibratory platform. The side of the nail hopper 1 has a nail outlet 101 that communicates with the vibratory feeder 2. Figure 2 As shown, the nail outlet 101 is connected to the opening on the side of the vibratory plate 2. When the vibratory platform vibrates, it vibrates and transmits the sealing nails 8 in the nail hopper 1 to the vibratory plate 2. The vibratory plate 2 and the nail hopper 1 can share a single vibratory platform, or they can each be set on a separate vibratory platform; this is not limited here.

[0062] To facilitate the addition of glue nails to the glue nail hopper 1, a feeding port is provided on the top surface of the glue nail hopper 1, and a conical feed hopper 102 is provided at the feeding port location, such as... Figure 2 As shown, by setting a conical feed hopper 102, the added glue nails can smoothly enter the glue nail hopper 1, avoiding waste caused by glue nails spilling.

[0063] To facilitate monitoring of the sealing nails 8 at the transfer nail preparation station 3, the liquid-filled sealing nail supply system of this invention also includes a second detection device (not shown in the figure), which is positioned above the transfer nail preparation station 3. Similarly, to monitor the nailing status at the battery 6, the liquid-filled sealing nail supply system of this invention also includes a third detection device (not shown in the figure), which is positioned at the nailing station 7, specifically diagonally above the battery 6. The specific height and angle relative to the battery 6 can be set by those skilled in the art as needed, preferably with a field of view covering all the liquid filling holes 601 positions of the battery 6. The first, second, and third detection devices are CCD cameras.

[0064] This invention relates to a liquid-filled sealing nail feeding system. An electromagnetic vibration platform drives a vibratory plate 2 to vibrate, causing the sealing nails 8 to rotate. A first detection device identifies the orientation of the sealing nails 8, ensuring they remain upright. A first robotic arm 4, a vacuum suction cup robotic arm, vacuum-adsorbs the sealing nails 8 from the vibratory plate 2 and places them on a transfer and preparation table 3. The second detection device positions the nails, ensuring they are precisely inserted into the first limiting hole 302. Simultaneously, a third detection device at the nailing table 7 ensures accurate nailing. This liquid-filled sealing nail feeding system allows for rapid compatibility and replacement of the sealing nails 8 simply by replacing the limiting plate 202 within the vibratory plate 2, saving on replacement costs.

[0065] This utility model discloses a liquid-filled sealing glue nail feeding system. It comprises a transfer nail preparation platform 3, a first robotic arm 4, and a second robotic arm 5. The first robotic arm 4 is solely responsible for transporting the glue nails to the transfer nail preparation platform 3, while the second robotic arm 5 transports the glue nails from the transfer nail preparation platform 3 to the battery 6. The first robotic arm 4 is a vacuum suction cup robotic arm that vacuum-releases the glue nails to the preparation position on the transfer nail preparation platform 3. The push rod 502 on the second robotic arm 5 pushes the sealing glue nail into the liquid injection hole 601, thus avoiding direct contact between the robotic arm and the surface of the battery 6. This prevents electrolyte contamination of the gripper 501, extends the service life of the gripper 501, and avoids contamination of the sealing glue nails 8 inside the vibratory feeder 2, reducing glue nail wear.
