Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to an electrode transfer tool. Background Technology

[0002] After die-cutting, lithium-ion battery electrodes are stacked in a cartridge holder, and then the cartridge holder containing the electrodes is transferred to the stacking or baking station. Typically, the cartridge holder includes a base plate and multiple uprights mounted on the base plate. These uprights form a confining space with a top opening, and the electrodes are placed into the cartridge holder from top to bottom through the opening. However, vibrations and bumps may occur during the transfer of the cartridge holder, causing the electrodes to shift position and potentially collide with and damage the uprights of the cartridge holder.

[0003] In existing technologies, some cartridge boxes are equipped with a top pressing mechanism, which is movably connected to the column. After the cartridge box is loaded with electrode sheets, the top pressing mechanism presses down on the top electrode sheets to prevent them from shifting during transportation. However, on the one hand, having a top pressing mechanism for each cartridge box increases the total cost of the electrode sheet transfer equipment; on the other hand, the top pressing mechanism makes the process of loading or unloading electrode sheets from the cartridge box inconvenient, affecting overall efficiency.

[0004] Therefore, there is an urgent need for an electrode transfer tool to solve the above problems. Utility Model Content

The limiting block is configured to position the magazine assembly along a second direction.

[0012] As an optional solution, the limiting block is provided with a sliding groove, and the height adjustment mechanism includes a sliding seat that can slide along the sliding groove so that the pressure plate assembly can be located above the limiting area or avoid the limiting area in the vertical direction.

The mounting plate is connected to the height adjustment mechanism, the pressing module is disposed on the lower side of the mounting plate, the elastic element connects the mounting plate and the pressing module, and the pressing module can squeeze the elastic element and form elastic pressing on the electrode sheet.

[0014] As an optional solution, the pressure plate assembly further includes a guide limiting member, which includes a sliding part and a limiting part. The cross-sectional area of ​​the limiting part is larger than that of the sliding part. The first end of the sliding part is connected to the pressing module, and the second end passes through the mounting plate and slides with the mounting plate. The limiting part is connected to the second end of the sliding part and is located on the side of the mounting plate opposite to the pressing module.

[0029] The beneficial effects of this utility model are:

[0030] This utility model discloses an electrode transfer fixture, comprising a clip assembly, a base assembly, a height adjustment mechanism, and a pressure plate assembly. In use, the clip assembly is first placed at the upstream station (e.g., the die-cutting station). Electrodes processed at the upstream station are sequentially loaded into the clip assembly through the opening at the top of the limiting cavity. At this point, there is no obstruction above the clip assembly, ensuring convenient electrode placement and improving electrode transfer efficiency. After the electrode collection is complete, the clip assembly is placed in the limiting area of ​​the base assembly. The height of the pressure plate assembly is then adjusted using the height adjustment mechanism, allowing it to extend into the limiting cavity from the opening and press against the uppermost electrode. The cooperation between the clip assembly and the pressure plate assembly limits and fixes the electrode, preventing damage due to positional shifts during transfer and improving electrode transport safety. When the electrode transfer fixture reaches the downstream station (e.g., stacking or baking),… When the electrode is in the working station, the pressure plate assembly is raised by the height adjustment mechanism and placed outside the clip assembly to facilitate the removal of the clip assembly from the base assembly. At this time, there is no obstruction above the opening of the clip assembly, which ensures the convenience of electrode removal and improves the electrode transfer efficiency. In addition, to improve the electrode transfer efficiency, multiple clip assemblies are usually set up in the actual production process. For example, one clip assembly is needed to receive the electrode to be processed at the upstream station, one clip assembly is needed to transfer the electrode between the upstream and downstream stations, and one clip assembly is needed to unload the electrode at the downstream station. The base assembly, height adjustment mechanism and pressure plate assembly of the electrode transfer fixture can be used as common structures and only used in conjunction with different clip assemblies during the transfer process between the two stations. Therefore, it is not necessary to configure a pressure plate assembly, base assembly and height adjustment mechanism for each clip assembly, thereby reducing the total cost of electrode transfer production.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0042] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] This embodiment provides an electrode transfer fixture, such as Figure 1 and Figure 2 As shown, the electrode transfer fixture includes at least one clip assembly 10, a base assembly 20, a height adjustment mechanism 30, and a pressure plate assembly 40. The clip assembly 10 has a limiting cavity 101 for accommodating the electrode 50. The top of the limiting cavity 101 has an opening for inserting and removing the electrode 50 into the limiting cavity 101, which can limit the electrode 50 in a horizontal plane. The base assembly 20 has a limiting area, and at least one clip assembly 10 can be selectively placed in the limiting area. The height adjustment mechanism 30 is connected to the base assembly 20, and the pressure plate assembly 40 is connected to the height adjustment mechanism 30. The height adjustment mechanism 30 is used to adjust the height of the pressure plate assembly 40 so that the pressure plate assembly 40 can extend into the limiting cavity 101 from the opening and press against the electrode 50.

[0046] In this embodiment, the electrode transfer fixture can be used by first placing the clip assembly 10 at the upstream station (e.g., the die-cutting station). Electrodes 50 processed at the upstream station are then sequentially loaded into the clip assembly 10 through the opening at the top of the limiting cavity 101. At this time, there is no obstruction above the clip assembly 10, ensuring convenient placement of the electrode 50 and improving the transfer efficiency. After the electrode 50 is collected, the entire clip assembly 10 is placed in the limiting area of ​​the base assembly 20. The height of the pressure plate assembly 40 is then adjusted by the height adjustment mechanism 30, allowing the pressure plate assembly 40 to extend into the limiting cavity 101 from the opening and press against the uppermost electrode 50. The cooperation between the clip assembly 10 and the pressure plate assembly 40 limits and fixes the electrode 50, preventing damage due to positional shifts during transfer and improving the safety of electrode transport. When the electrode transfer fixture reaches the downstream station (e.g., the stacking or baking station), the height adjustment mechanism 30... The pressure plate assembly 40 is raised and placed above the clip assembly 10 to facilitate the removal of the clip assembly 10 from the base assembly 20. At this time, the opening of the clip assembly 10 is unobstructed, thus ensuring the convenience of removing the electrode 50 and improving the transfer efficiency of the electrode 50. In addition, to improve the transfer efficiency of the electrode 50, multiple clip assemblies 10 are set up for coordinated transfer in the actual production process. For example, when one clip assembly 10 receives the electrode 50 to be processed at the upstream station, one clip assembly 10 transfers the electrode 50 between the upstream and downstream stations, and one clip assembly 10 unloads the electrode 50 at the downstream station. The base assembly 20, height adjustment mechanism 30 and pressure plate assembly 40 of the electrode transfer fixture can be used as common structures and only used in conjunction with different clip assemblies 10 when transferring between two stations. Therefore, it is not necessary to configure a pressure plate assembly 40, base assembly 20 and height adjustment mechanism 30 for each clip assembly 10, thereby reducing the cost of transfer production.

[0047] like Figure 1 As shown, in this embodiment, the electrode 50 is a rectangular electrode. The magazine assembly 10 includes a magazine base plate 11 and several posts 12. The posts 12 are mounted on the upper side of the magazine base plate 11, thereby forming a limiting cavity 101 with a top opening. This design is not only simple in structure but also lightweight. In this embodiment, the magazine assembly 10 includes four posts 12. The four posts 12 together form a limiting cavity 101 with a cross-sectional size approximately matching that of the electrode 50, thus reliably limiting the position of the electrode 50 in the horizontal plane. In this embodiment, the cross-section of the posts 12 is L-shaped, and each post 12 surrounds one corner of the electrode 50. That is, the posts 12 surround and protect the easily damaged parts of the electrode 50, thereby further improving the safety of the electrode 50 during transport. It is understood that in other embodiments, the specific structure of the magazine assembly 10 is not limited, as long as it can form a limiting cavity 101 with a top opening that can limit the electrode 50 in the horizontal plane.

[0048] like Figure 2 As shown, two mutually perpendicular directions within the horizontal plane are defined as the first direction and the second direction, respectively. The base assembly 20 includes a base plate 21, two side plates 22, and a limiting block 23. The two side plates 22 are disposed opposite each other on the base plate 21 along the first direction, and the limiting block 23 is connected to the base plate 21. The two side plates 22 and the limiting block 23 enclose a limiting area. When the magazine assembly 10 is placed in the limiting area, the two side plates 22 respectively limit the magazine assembly 10 along the first direction, and the limiting block 23 positions the magazine assembly 10 along the second direction, thereby ensuring that the magazine assembly 10 can be aligned vertically with the pressure plate assembly 40, and ensuring that the pressure plate assembly 40 can accurately extend from the opening of the magazine assembly 10 into the limiting cavity 101. In this embodiment, the base plate 21 and the two side plates 22 can be integrally formed, or they can be formed separately and then connected and fixed by a fastening structure. Optionally, the limiting block 23 is disposed between the two side plates 22. In other embodiments, if the dimension of the side plate 22 along the second direction is small, the limiting block 23 may not be located between the two side plates 22.

[0049] like Figure 2 As shown, the limiting block 23 is provided with a sliding groove 231, and the height adjustment mechanism 30 includes a sliding seat 34. The sliding seat 34 can slide along the sliding groove 231 so that the pressure plate assembly 40 can be located above the limiting area or vertically avoid the limiting area. When the magazine assembly 10 is placed on the base assembly 20, the sliding seat 34 can be pushed to the end of the sliding groove 231 away from the limiting area so that the pressure plate assembly 40 vertically avoids the limiting area, ensuring that there is no obstruction above the limiting area, thereby improving the ease of operation when the magazine assembly 10 is placed on the base assembly 20; after the magazine assembly 10 is placed in the limiting area, the sliding seat 34 is pushed to the end of the sliding groove 231 close to the limiting area so that the pressure plate assembly 40 is located directly above the limiting area so that the pressure plate assembly 40 can accurately extend into the limiting cavity 101 of the magazine assembly 10. Similarly, when removing the magazine assembly 10 from the base assembly 20, the pressure plate assembly 40 is first raised above the magazine assembly 10 by the height adjustment mechanism 30. Then, the sliding seat 34 is pushed to the end of the slide groove 231 away from the limiting area, so that the pressure plate assembly 40 avoids the limiting area in the vertical direction, ensuring that there is no obstruction structure above the limiting area, and improving the ease of operation when removing the magazine assembly 10 from the base assembly 20.

[0050] In this embodiment, as Figure 2As shown, the slide groove 231 extends along the first direction, and the limiting block 23 is provided with a stop 232 at both ends of the slide groove 231 along the first direction. The stop 232 is used to limit the position of the sliding seat 34 along the first direction. Specifically, when the sliding seat 34 abuts against the stop 232 near the limiting area, the pressure plate assembly 40 is located directly above the limiting area. When the sliding seat 34 abuts against the stop 232 away from the limiting area, the pressure plate assembly 40 avoids the limiting area in the vertical direction. In addition, the two stop 232 can also prevent the sliding seat 34 from coming out of the two ends of the slide groove 231 in the first direction. Optionally, the longitudinal section of the sliding seat 34 is "I" shaped, while the cross section of the slide groove 231 is "⊥" shaped. After the sliding seat 34 is inserted into the slide groove 231, it can limit the sliding seat 34 in the vertical direction, preventing the sliding seat 34 from coming out of the slide groove 231 in the vertical direction.

[0051] like Figure 2 and Figure 3 As shown, the height adjustment mechanism 30 also includes a support rod 31, a mounting base 32, and a transmission assembly 33. The lower end of the support rod 31 is connected to a sliding seat 34. The mounting base 32 can slide vertically relative to the support rod 31. The pressure plate assembly 40 is connected to the mounting base 32. The transmission assembly 33 drives the mounting base 32 and the support rod 31 and is configured to receive power input. When the power source drives the transmission assembly 33, the mounting base 32 slides vertically relative to the support rod 31, thereby driving the pressure plate assembly 40 to move up and down. In this embodiment, the transmission assembly 33 can be driven manually. In this case, the electrode transfer fixture does not need an electric drive source or power distribution, thus simplifying the structure and reducing costs. Of course, in other embodiments, an electric drive source can input power to the transmission assembly 33 to cause the mounting plate to move up and down relative to the support rod 31.

[0052] In this embodiment, as Figure 2 As shown, the support rod 31 extends vertically. The mounting base 32 is provided with a through groove 321, which extends vertically. The support rod 31 passes through the through groove 321 and slides within it. This means that the support rod 31 not only provides support but also guides the movement of the mounting base 32. Optionally, the cross-section of the support rod 31 includes a rounded edge, and correspondingly, the cross-section of the through groove 321 also includes a corresponding rounded edge, thereby ensuring the smoothness of the lifting and lowering process of the mounting base 32.

[0053] like Figure 3As shown, the transmission assembly 33 includes a rack 331, a gear 332, a rotating shaft 333, a worm gear 334, and a worm 335. The rack 331 is mounted on the support rod 31 and extends vertically. The gear 332 is rotatably mounted on the mounting base 32 via the rotating shaft 333 and meshes with the rack 331. The worm gear 334 is connected to the rotating shaft 333. The worm 335 is rotatably mounted on the mounting base 32 and engages with the worm gear 334. When the worm 335 is driven to rotate, the worm gear 334, the rotating shaft 333, and the gear 332 rotate synchronously. Based on the meshing relationship between the gear 332 and the rack 331, the gear 332 drives the rotating shaft 333, the worm gear 334, the worm 335, and the mounting base 32 to move up and down synchronously along the rack 331, thereby achieving height adjustment of the pressure plate assembly 40. Furthermore, it should be noted that the worm gear 334 and worm 335 have a self-locking function. Therefore, when the pressure plate assembly 40 is adjusted to a certain height, it can be stably maintained at that height without the need for an additional locking structure. This not only simplifies the structure but also makes operation more convenient. Of course, in other embodiments, the specific structure of the transmission assembly 33 is not limited to this. As long as it can drive the mounting base 32 to move up and down along the support rod 31 when power is input, it is acceptable. For transmission assemblies 33 without a self-locking function, an additional locking structure can be provided to lock the positions of the mounting base 32 and the support rod 31.

[0054] In this embodiment, as Figure 2 As shown, the mounting base 32 is also provided with a clearance groove 322, which extends vertically through the mounting base 32 and communicates with the through groove 321. The clearance groove 322 is used to avoid the installation of the rack 331. The height adjustment mechanism 30 also includes a handle 35, which is connected to the worm gear 335 and is used by the user to hold and drive the worm gear 335 to rotate, improving the convenience of operation. In this embodiment, the mounting base 32 is also provided with a receiving cavity, which communicates with the clearance groove 322. At least part of the transmission component 33 is disposed in the receiving cavity, thereby protecting the transmission component 33, avoiding transmission failure caused by external interference factors, and improving the service life of the electrode transfer fixture.

[0055] like Figure 2 and Figure 4As shown, the pressure plate assembly 40 includes a mounting plate 41, an elastic element 42, and a pressing module 43. The mounting plate 41 is connected to the height adjustment mechanism 30. In this embodiment, the mounting plate 41 is connected to the mounting base 32. The pressing module 43 is disposed on the lower side of the mounting plate 41. The elastic element 42 connects the mounting plate 41 and the pressing module 43. The pressing module 43 can squeeze the elastic element 42 and elastically press against the electrode 50. On the one hand, when the pressure plate assembly 40 and the electrode 50 are adjusted to press against each other by the height adjustment mechanism 30, the pressing module 43 can generate a certain amount of compression in the elastic element 42, so that the pressing module 43 presses against the electrode 50 with a certain pre-tightening force, which ensures that the electrode 50 is reliably fixed and does not cause the electrode 50 to be damaged due to excessive force. On the other hand, during the transfer of the electrode 50, if the electrode transfer fixture is bumped, the elastic element 42 can play a certain buffering role, filter a certain amount of vibration, reduce the micro-displacement of the electrode 50 caused by vibration, and thus reduce the risk of damage to the electrode 50. Optionally, in this embodiment, the pressure plate assembly 40 includes a plurality of elastic elements 42, which are evenly arranged between the mounting plate 41 and the pressing module 43, thereby making the force on the pressing module 43 more uniform and the force exerted by the pressing module 43 on the electrode 50 more uniform.

[0056] like Figure 4 As shown, the pressure plate assembly 40 also includes a guide and limiting member 44, which includes a sliding part 441 and a limiting part 442. The cross-sectional area of ​​the limiting part 442 is larger than that of the sliding part 441. The first end of the sliding part 441 is connected to the pressing module 43, and the second end passes through the mounting plate 41 and slides in cooperation with the mounting plate 41. The limiting part 442 is connected to the second end of the sliding part 441 and is located on the side of the mounting plate 41 away from the pressing module 43. On the one hand, the sliding cooperation between the sliding part 441 and the mounting plate 41 can guide the movement of the pressing module 43, preventing the pressing module 43 from tilting relative to the mounting plate 41 and affecting the uniformity of pressing the electrode 50. On the other hand, the setting of the limiting part 442 can ensure a reliable connection between the mounting plate 41 and the pressing module 43, preventing them from separating from each other. It is understandable that when the pressure plate assembly 40 does not press against the pressure plate 50, the limiting part 442 abuts against the surface of the mounting plate 41 away from the pressing module 43, and at this time the elastic member 42 is in its original length state or slightly compressed state.

[0057] In this embodiment, the pressure plate assembly 40 includes four guide limiting members 44, which are arranged at the four corners of the pressing module 43. In other embodiments, the number of guide limiting members 44 can be flexibly adjusted according to actual needs, and is not limited here.

[0058] like Figure 4As shown, the elastic element 42 is sleeved on the sliding part 441. This arrangement allows the guide limiting element 44 to also guide the deformation direction of the elastic element 42, ensuring smoother movement of the pressing module 43 relative to the mounting plate 41. In this embodiment, one elastic element 42 is sleeved on each guide limiting element 44.

[0059] like Figure 4 As shown, the pressing module 43 includes a main body plate 431 and a contact plate 432. The first ends of the elastic member 42 and the sliding part 441 are both connected to the main body plate 431. The contact plate 432 is disposed on the side of the main body plate 431 opposite to the mounting plate 41 and is used to contact the electrode 50. The contact plate 432 is made of a flexible material. By making the part of the pressing module 43 that contacts the electrode 50 made of a flexible material, rigid collisions between the pressing module 43 and the electrode 50 during contact can be avoided, thereby preventing damage to the electrode 50 from impacts. Optionally, the contact plate 432 is made of rubber.

[0060] In this embodiment, the main body plate 431 includes a first protrusion 4311 located on the side of the mounting plate 41. The contact plate 432 includes a second protrusion 4323 located below the first protrusion 4311. The first protrusion 4311 and the second protrusion 4323 are connected by fasteners 433, thereby achieving a fixed connection between the main body plate 431 and the contact plate 432. Optionally, multiple sets of the first protrusion 4311 and the second protrusion 4323 can be provided to ensure the reliability of the connection between the main body plate 431 and the contact plate 432. Of course, in other embodiments, the main body plate 431 and the contact plate 432 can also be connected by adhesive bonding, which is not specifically limited here.

[0061] like Figure 4 As shown, the contact plate 432 includes a body portion 4321 and anti-slip protrusions 4322. The body portion 4321 is connected to the main plate 431, and the anti-slip protrusions 4322 are disposed on the lower side of the body portion 4321. The anti-slip protrusions 4322 are used to press against the electrode 50. By providing the anti-slip protrusions 4322, horizontal relative displacement between the electrode 50 and the pressing module 43 can be prevented during transportation, thereby improving the fixing effect of the pressure plate assembly 40 on the electrode 50 and thus improving the safety of the electrode 50 during transportation. Optionally, in this embodiment, the contact plate 432 includes a plurality of anti-slip protrusions 4322, which are evenly arranged on the body portion 4321.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. For those skilled in the art, based on the concept of this utility model, there will be changes in the specific implementation methods and application scope.
