Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing technology, and in particular to a lithium battery sealing body conveying device. Background Technology

[0002] The lithium battery sealing body (also called a sealing cap or sealing plate) is a crucial part of the lithium battery structure. It primarily seals the battery's external structure, ensuring the safety of the internal chemicals and electrolyte, and plays a vital role in the battery's performance and safety. The patent disclosed in CN220077828U, titled "A Novel Lithium Battery Cell Transfer and Tilting Device," likely addresses this issue. This device features automated transfer equipment and vacuum suction arms capable of efficiently and stably gripping and transporting goods. The suction cup spacing on the vacuum suction arms is adjustable. The goods (lithium battery sealing bodies) picked up by the vacuum suction arms are typically transferred to a shelf, some of which have grooves to hold the sealing bodies. However, as the sealing bodies are conveyed and eventually converge, a positioning mechanism is used to adjust the spacing between them to match the distance between the suction cups and the grooves, ensuring the distance between the sealing bodies equals the distance between the suction cups and the grooves. However, when changing batches, the groove spacing on the same-sized placement plate will become larger or smaller. At this time, the previous positioning mechanism will no longer be able to separate the lithium battery seal body according to the specified spacing, and thus will no longer be able to perform its function. Utility Model Content

[0003] The purpose of this invention is to address the problem that the center-to-center spacing of lithium battery sealing bodies of different sizes is different, and that a specific positioning mechanism cannot adaptively adjust it, by proposing a lithium battery sealing body conveying device.

[0004] The technical solution of this utility model is as follows: A lithium battery sealing body conveying device, including a feeding mechanism and a conveying mechanism. The feeding mechanism is provided with lithium battery sealing bodies that are conveyed to the conveying mechanism. It also includes: multiple support frames that are interconnected and arranged on the conveying mechanism. Vacuum suction cup arms are provided inside the support frames. Multiple linear drive mechanisms that drive the vacuum suction cup arms to move up, down, left, and right are also provided inside the support frames; a placement plate that is stacked in the support frames to place the goods on the vacuum suction cup arms. The placement plate has multiple grooves with the same spacing; and multiple baffles fixedly installed on the support frames. The upper surface of one of the baffles is provided with a positioning mechanism that is replaced according to the spacing between the grooves.

[0005] Optionally, the positioning mechanism includes an L-shaped bracket fixedly mounted on the baffle, a cylinder fixedly connected to the top of the L-shaped bracket, a driving plate fixedly connected to the piston rod of the cylinder, and a first positioning plate corresponding to the placement plate fixedly connected to the cylinder on the side of the driving plate away from the placement plate. The first positioning plate has multiple first positioning slots arranged in a linear pattern and corresponding to the grooves on the placement plate.

[0006] Optionally, the positioning mechanism further includes a second positioning plate and a third positioning plate movably mounted on the L-shaped bracket. The second positioning plate has multiple second positioning slots, and the third positioning plate has multiple third positioning slots. The first positioning plate is connected to the driving plate by a first bolt, and the second and third positioning plates are connected to the L-shaped bracket by a second bolt. The first and second bolts are of the same type and have the same spacing.

[0007] Optionally, the support frame is provided with a conveying track for receiving and feeding the lithium battery sealing body in the feeding mechanism. The conveying track is located directly below the vacuum suction cup arm and has a sliding slot for the first positioning plate, the second positioning plate and the third positioning plate to be inserted. The conveying track is provided with a conveying groove for the lithium battery sealing body to slide to the bottom of the vacuum suction cup arm. The bottom of the vacuum suction cup arm is provided with multiple suction cups that are adjustable according to the groove spacing.

[0008] Optionally, a guide plate is fixedly connected to the top of the L-shaped bracket, and guide rods are movably connected to both ends of the guide plate.

[0009] Optionally, a pair of guide rods are symmetrically arranged at both ends of the top of the L-shaped bracket.

[0010] Optionally, the bottom end of the support frame is fixedly connected to a base for support.

[0011] Optionally, the support frame is made of modular aluminum alloy and is connected by bolts, pins, corner brackets or quick-release fasteners.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes a combination of a vacuum suction cup arm, a linear drive mechanism, a placement plate, grooves, and a positioning mechanism. Based on the spacing between the grooves on different batches of placement trays, the corresponding first, second, or third positioning plate can be quickly replaced. This ensures that the distance between the sealed lithium batteries held by the suction cup is precisely consistent with the spacing of the grooves on the placement plate, preventing accidental gripping or misalignment by the suction cup and thus improving the accuracy of the entire handling process.

[0014] Furthermore, because the positioning mechanism can flexibly adapt to different groove spacings, it can quickly handle lithium battery seals of different sizes and batches. This flexible system adaptability provides greater flexibility to the production line, enabling rapid switching between production modes to meet the needs of different customers or products.

[0027] Example

[0028] like Figure 1 , Figure 2 Figure 3As shown, this utility model proposes a lithium battery sealing body conveying device, including a feeding mechanism 1 and a conveying mechanism 2. The conveying mechanism 2 includes a vibrating feeding mechanism. A motor drives the disc to vibrate. The motor generates vibration through an eccentric shaft, causing the disc and the material inside (such as the lithium battery sealing body) to vibrate, roll, slide, or jump. This vibration guides the sealing body along the disc surface, ultimately delivering it to a designated position. The feeding mechanism 1 contains lithium battery sealing bodies 5 that are conveyed to the conveying mechanism 2. The most basic function of the lithium battery sealing body 5 is to prevent external substances (such as air, moisture, etc.) from entering the battery, and to prevent leakage of electrolyte or gas inside the battery, ensuring the stability and safety of the battery. Lithium batteries produce gas during use, and in practice, they usually have a certain pressure release function (such as a safety valve). Simultaneously, when the internal pressure of the battery is too high, the lithium battery sealing body 5 can automatically release gas to prevent the battery from expanding or exploding. Furthermore, the lithium battery sealing body 5 has a positive electrode connection terminal (such as copper foil or aluminum foil) connected to the positive electrode plate of the battery. It connects the battery seal to the battery electrodes through welding or other connection methods, completing the current conduction of the battery. The lithium battery seal 5 sometimes also involves thermal management, especially in the design of high-energy-density batteries. The lithium battery seal 5 contains heat-conducting materials to help dissipate heat better inside the battery and prevent overheating. Finally, the lithium battery seal 5 sometimes also incorporates safety designs to avoid the risk of internal short circuits when the battery is subjected to impact or pressure. For example, the safety valve on the lithium battery seal 5 can automatically disconnect or release pressure under certain conditions, thereby reducing the risk of short circuits or overcharging. Furthermore, the conveying mechanism 2 is equipped with multiple interlocking support frames 21. The support frames 21 are made of modular aluminum alloy and are connected by bolts, pins, corner brackets, or quick-release fasteners. A base 28 for support is fixedly connected to the bottom of the support frame 21. A vacuum suction cup arm 23 is installed inside the support frame 21. The vacuum suction cup arm 23 is a robotic arm that uses vacuum suction to grasp, transport, and place objects. It combines suction cup technology and robotics technology, and is widely used in industrial automation, production lines, logistics, and assembly, especially suitable for handling irregular, fragile, or smooth-surfaced items, such as lithium battery seals 5. The support frame 21 also houses at least three linear drive mechanisms 22 that move the vacuum suction cup arm 23 up, down, left, and right. The principle behind the coordinated movement of multiple linear drive mechanisms to achieve three-dimensional motion lies in coordinating the independent movements of multiple linear drive systems, enabling the object to freely position and move in three-dimensional space. Specifically, when an object needs to move freely in space along the X, Y, and Z axes (i.e., the three axes of the three-dimensional coordinate system), at least three linear drive mechanisms are required.These drive mechanisms, through precise control and coordination, enable objects to translate independently in three directions, thereby achieving position control in three-dimensional space. A placement plate 25, stacked within the support frame 21, holds the goods on the vacuum suction cup arm 23. The placement plate 25 has multiple equally spaced grooves 26. Multiple baffles 27 are fixedly mounted on the support frame 21 to protect the mechanisms within the support frame 21 from damage. One of the baffles 27 has a positioning mechanism on its upper surface that allows it to be replaced according to the spacing between the grooves 26.

[0029] In this embodiment, as shown... Figure 4 As shown, the positioning mechanism also ensures consistent spacing during gripping, preventing the lithium battery sealing body 5 from being accidentally sucked in or not being gripped when the suction cup 24 grasps it, thus reducing defects in the production process. Furthermore, quickly changing the positioning mechanism and ensuring consistent spacing of the lithium battery sealing body 5 during suction cup gripping can effectively improve the efficiency of the production line. Especially in situations where production batches change frequently, quickly adjusting the positioning mechanism to adapt to different spacing variations can significantly reduce downtime caused by manual adjustments or equipment resets.

[0030] Please see further. Figure 4 , Figure 5 The positioning mechanism includes an L-shaped bracket 3 fixedly installed on the baffle 27. A guide plate 6 is fixedly connected to the top of the L-shaped bracket 3. Guide rods 61 are movably connected to both ends of the guide plate 6. The guide rods 61 are used to guide the lithium battery sealing body 5 to the correct placement position, ensuring that each lithium battery sealing body 5 can be accurately aligned with the predetermined contact point or terminal. A pair of guide rods 61 are symmetrically arranged at both ends of the top of the L-shaped bracket 3. A cylinder 31 is fixedly connected to the top of the L-shaped bracket 3. A driving plate 32 is fixedly connected to the piston rod of the cylinder 31. A first positioning plate 33 corresponding to the placement plate 25 is fixedly connected to the cylinder 31 on the side away from the driving plate 32. A plurality of first positioning slots 34 are arranged in a linear pattern and correspond to the grooves 26 on the placement plate 25. The first positioning slots 34 are arc-shaped grooves that hold the lithium battery sealing body 5. When the first positioning plate 33 moves toward the lithium battery sealing body 5, the lithium battery sealing body 5 can be automatically separated, and the separation distance is equal to the distance of the grooves 26 on the corresponding placement plate 25.

[0031] The positioning mechanism also includes a second positioning plate 35 and a third positioning plate 37 movably mounted on the L-shaped bracket 3. The second positioning plate 35 and the third positioning plate 37 operate on the same principle as the first positioning plate 33. The second positioning plate 35 has multiple second positioning slots 36, and the third positioning plate 37 has multiple third positioning slots 38. The first positioning plate 33 is connected to the driving plate 32 by a first bolt, and the second positioning plate 35 and the third positioning plate 37 are connected to the L-shaped bracket 3 by a second bolt. The first bolt and the second bolt are of the same type and have the same spacing.

[0032] Furthermore, the support frame 21 is internally equipped with a conveyor track 4 that transports the lithium battery sealing bodies 5 within the receiving and feeding mechanism 1. The main function of the conveyor track 4 is to achieve automated transportation of materials or products. Through the design of the track, materials can be continuously and stably transported from one place to another, thereby improving production efficiency and reducing manual intervention. At the same time, using the conveyor track 4 can also reduce manual handling time, avoid material loss during transmission, and improve the working efficiency of the production line. Modern conveyor tracks 4 often combine automation technology, using sensors and control systems to achieve precise control, automatic detection, sorting, and steering functions. Furthermore, the conveyor track 4 can also ensure that materials remain stable during transportation, preventing accidents such as leakage, collision, or falling, and is especially suitable for transporting fragile or hazardous materials. The conveyor track 4, located directly below the vacuum suction cup arm 23, has sliding slots 42 for the first positioning plate 33, the second positioning plate 35, and the third positioning plate 37 to engage. Inside the conveyor track 4 is a conveyor chute 41 for the lithium battery sealing body 5 to slide to the location directly below the vacuum suction cup arm 23. A conveyor belt is installed within the conveyor chute 41 to move the lithium battery sealing body 5 to a designated position. The bottom of the vacuum suction cup arm 23 has multiple suction cups 24, adjustable according to the spacing of the grooves 26. Each suction cup 24 is a device that uses vacuum principles to grasp, move, or manipulate objects. It is typically made of soft and elastic materials such as rubber, silicone, or polyurethane, allowing it to adhere tightly to the object's surface. When the suction cup 24 contacts an object, negative pressure is generated by evacuating air, creating an adhesive force between the suction cup 24 and the object's surface, thus firmly gripping the object. Due to the pressure difference, the internal pressure of the suction cup 24 is much lower than the external environmental pressure, causing the suction cup to adhere firmly to the object's surface. Finally, once suction cup 24 contacts and successfully adheres to the object, the suction cup arm can move the object. After the task is completed, the vacuum is released to allow the suction cup to release the object.

[0033] In this embodiment, when a lithium battery sealing body conveying device is required, such as Figure 1 and Figure 4 As shown, the lithium battery sealing body 5 in the feeding mechanism 1 is transported via the conveying chute 41 in the conveying track 4 to the area directly below the suction cup 24 at the bottom of the vacuum suction cup arm 23. Figure 3 and Figure 5As shown, at this time, the first positioning plate 33, the second positioning plate 35, or the third positioning plate 37 is replaced according to the spacing of the grooves 26 on the placement plate 25, so that the spacing between the first positioning slot 34 on the first positioning plate 33, the second positioning slot 36 on the second positioning plate 35, or the third positioning slot 38 on the third positioning plate 37 is equal to the spacing of the grooves 26 on the placement plate 25. When the first positioning plate 33 is installed on the driving plate 32, the cylinder 31 at the top of the L-shaped bracket 3 is activated. The cylinder 31 pushes the driving plate 32 and the first positioning plate 33 to move in sequence. The first positioning plate 33 moves along the sliding slot 42 to the multiple lithium battery sealing bodies 5 in the conveying chute 41 until the first positioning slot 34 is engaged with the corresponding lithium battery sealing body 5. At the same time, as Figure 4 As shown, the spacing between the suction cups 24 at the bottom of the vacuum suction cup arm 23 needs to be adjusted beforehand to correspond with the first positioning slot 34. Finally, the vacuum suction cup arm 23 can be started. For example... Figure 3 and Figure 4 As shown, the suction cups 24 at the bottom of the vacuum suction cup arm 23 all pick up the lithium battery seal body 5 in the corresponding first positioning slot 34. Then, through the cooperation of multiple linear drive mechanisms 22 and the vacuum suction cup arm 23, the suction cups 24 at the bottom of the vacuum suction cup arm 23 pick up the lithium battery seal body 5 and transport it to the groove 26 on the placement plate 25. This operation is repeated until all the grooves 26 on the placement plate 25 are filled. When replacing the second positioning plate 35 or the third positioning plate 37, the above operation is performed simultaneously, which will not be elaborated here.

[0034] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
