[0030] At present, the existing graphite frame assembly is to place the battery cells in the battery cell slots for coating without any reinforcement, which leads to the phenomenon that the battery cells are prone to falling when the graphite frame assembly is placed vertically.

[0031] To solve the above problems, refer to Figure 1-Figure 5 , Figure 1A partial exploded view of a frame assembly provided in an embodiment of the present application is shown. Figure 2 The schematic diagram of the first limiting member, limiting ring and driving member in the first state is shown, Figure 3 The schematic diagram of the second limiting member, limiting ring and driving member in the first state is shown, Figure 4 The schematic diagram of the first limiting member, limiting ring and driving member in the second state is shown, Figure 5 A schematic diagram of a second type of limiting member, limiting ring and driving member in a second state is shown.

[0032] The present application provides a frame assembly for carrying a battery cell 3. The frame assembly includes a frame 1 and a limit member 2. The frame 1 is provided with a carrying slot 11 for carrying the battery cell 3. The limit member 2 is located on the peripheral side of the carrying slot 11 and is rotatably connected to the frame 1. The limit member 2 is provided with a limit portion 211 extending out of the peripheral side of the limit member 2. The limit portion 211 is driven to rotate by the rotation of the limit member 2, and the limit member 2 switches between a first state and a second state. In the first state, one end of the limit portion 211 away from the limit member 2 is located on the peripheral side of the carrying slot 11, so as to facilitate the placement of the battery cell 3 into the carrying slot 11 or to remove it from the carrying slot 11. In the second state, one end of the limit portion 211 away from the limit member 2 extends into the carrying slot 11 to prevent the battery cell 3 from falling off the carrying slot 11.

[0033] It should be understood that the frame assembly includes a frame 1, the material of the frame 1 can be graphite material, the frame 1 is provided with a carrying groove 11, the carrying groove 11 is used to carry the battery cell 3, the present application does not limit the shape of the carrying groove 11, and the shape of the carrying groove 11 is conformal to the battery cell 3.

[0034] The frame assembly also includes a limit member 2 located on the side of the bearing groove 11, and the limit member 2 is rotatably connected to the frame 1. The limit member 2 can rotate around its own central axis. The present application does not limit the way in which the limit member 2 is rotatably connected to the frame 1. In one example, the limit member 2 is provided with a protrusion or a groove, and the frame 1 is provided with a corresponding groove or a protrusion, wherein the protrusion is cylindrical, and when the protrusion is engaged with the groove, the limit member 2 is rotatably connected to the frame 1. Furthermore, in order to prevent the limit member 2 from being separated from the frame 1, a corresponding limit structure can also be provided. In one example, the limit member 2 and the frame 1 can also be connected by threads. When rotating the limit member 2, it can be rotated manually by an operator, or it can be rotated by a driving member such as a motor, and the present application does not impose any restrictions.

[0035] The limiting member 2 is provided with a limiting portion 211, which extends out of the peripheral side of the limiting member 2. The limiting portion 211 can be located on the peripheral side of the bearing slot 11 or can extend into the bearing slot 11. When the limiting portion 211 is located on the peripheral side of the bearing slot 11, it does not block the battery cell 3, so that the battery cell 3 can be placed in the bearing slot 11. When the limiting portion 211 is located in the bearing slot 11, it blocks the battery cell 3, which can prevent the battery cell 3 from being separated from the bearing slot 11. In order to avoid affecting the coating of the battery cell 3, the width of the limiting portion 211 needs to be set as small as possible, and the specific size can be set according to the usage.

[0036] The present application does not limit the rotation angle of the limiting member 2, but if the limiting portion 211 extends into the supporting groove 11, and the limiting portion 211 is vertically arranged to the side wall of the supporting groove 11 where the limiting portion 211 is located, the limiting portion 211 has the best blocking effect on the battery cell 3, further preventing the battery cell 3 from detaching from the supporting groove 11.

[0037] When in use, if it is necessary to assemble or discharge the battery cell 3, it is in the first state, and the limit member 2 is rotated. The limit member 2 rotates and drives the limit portion 211 to rotate, so that the end of the limit portion 211 away from the limit member 2 is located on the peripheral side of the supporting groove 11, that is, the limit portion 211 is not located in the supporting groove 11, and does not affect the loading or discharging of the battery cell 3. At this time, it is convenient to put the battery cell 3 into the supporting groove 11 or remove it from the supporting groove 11.

[0038] When the battery cell 3 is assembled, it is necessary to limit the battery cell 3 in the second state, rotate the limit member 2, the limit member 2 rotates and drives the limit portion 211 to rotate, so that the end of the limit portion 211 away from the limit member 2 extends into the supporting groove 11 to prevent the battery cell 3 from detaching from the supporting groove 11.

[0039] The present application sets a limit member 2 at the frame 1, and the state of the limit member 2 can be set according to different situations, so that when assembling or discharging the battery cell 3, the limit member 2 is located on the peripheral side of the supporting groove 11, and the limit member 2 does not block the supporting groove 11. After the assembly is completed, the limit member 2 extends into the supporting groove 11 to block the battery cell 3, which can effectively prevent the battery cell 3 from falling when the frame 1 is placed vertically in HWCVD (hot wire chemical vapor deposition), reduce the generation of fragments, and through effective limiting, the battery cell 3 can be made to fit more closely in the supporting groove 11, effectively isolating the occurrence of the plating wrap phenomenon, improving production efficiency, and increasing product yield.

[0040] Reference Figure 2-Figure 7 , Figure 6 An exploded view of the first limiting member and limiting ring provided in an embodiment of the present application is shown. Figure 7 An exploded view of a second type of limiting member and limiting ring provided in an embodiment of the present application is shown.

[0041] In some optional embodiments, the frame 1 is penetrated by a mounting hole, a limiting ring 12 is installed in the mounting hole, a first guide portion 121 is provided on the inner wall of the limiting ring 12, the limiting member 2 is provided in a cylindrical shape, the limiting member 2 is located in the inner cavity of the limiting ring 12 and is coaxially arranged with the limiting ring 12, a second guide portion 221 is provided on the outer wall of the limiting member 2, either the first guide portion 121 or the second guide portion 221 is a spiral groove, and the other is a protrusion located in the spiral groove. The frame 1 is penetrated by a mounting hole, the mounting hole is in the shape of a circular hole, the limiting ring 12 is provided in a circular ring, the limiting ring 12 is located in the mounting hole and is detachably connected to the frame 1, so as to facilitate the assembly of the limiting ring 12 and the limiting member 2, and the connection method can be connected by means of snap connection, etc., which is not limited in this application. The limiting member 2 is located in the inner cavity of the limiting ring 12 and the two are coaxially arranged.

[0042] The limiting ring 12 is provided with a first guide portion 121 relative to the side wall of the limiting member 2, and the limiting member 2 is provided with a second guide portion 221 relative to the side wall of the limiting ring 12. When the second guide portion 221 slides relative to the first guide portion 121, the limiting member 2 moves along the axial direction of the limiting ring 12 and rotates around its own central axis, so that the limiting member 2 can rotate, thereby adjusting the limiting portion 211 to be located in the bearing groove 11 or on the peripheral side of the bearing groove 11. The present application can adjust the rotation angle of the limiting member 2 by adjusting the length of the spiral groove, thereby facilitating operator control, for example: the length of the spiral groove is set to only allow the limiting member 2 to rotate 90°, and the position of the limiting portion 211 of the limiting member 2 is controlled by forward or reverse rotation, for example: when the limiting member 2 rotates forward 90°, the limiting portion 211 is located on the peripheral side of the bearing groove 11, and when the limiting member 2 rotates reversely 90°, the limiting portion 211 extends into the bearing groove 11.

[0043] In one example, the first guide portion 121 is a protrusion, the second guide portion 221 is a spiral groove, the first guide portion 121 is located in the second guide portion 221 , and the second guide portion 221 extends spirally along the outer circumference of the limiting member 2 .

[0044] In one example, the second guide portion 221 is a protrusion, the first guide portion 121 is a spiral groove, the second guide portion 221 is located in the first guide portion 121 , and the first guide portion 121 extends spirally along the inner circumference of the limiting ring 12 .

[0045] The present application does not limit the position of the limiting portion 211 due to the axial position of the limiting member 2 in the limiting ring 12. For example, when the limiting member 2 rises and rotates relative to the limiting ring 12, the limiting portion 211 extends into the bearing groove 11 or can be located on the peripheral side of the bearing groove 11; when the limiting member 2 descends and rotates relative to the limiting ring 12, the limiting portion 211 can be located on the peripheral side of the bearing groove 11 and also extend into the bearing groove 11.

[0046] In one example, the limit member 2 rotates while rising relative to the limit ring 12, and the limit portion 211 is located on the peripheral side of the supporting slot 11 to facilitate placing the battery cell 3 into the supporting slot 11; when the battery cell 3 is placed in the supporting slot 11, the limit member 2 rotates while descending relative to the limit ring 12, and the limit portion 211 extends into the supporting slot 11 to limit the battery cell 3, thereby preventing the battery cell 3 from detaching from the supporting slot 11 and making the battery cell 3 fit the supporting slot 11 more closely.

[0047] If the limiting member 2 is to move relative to the limiting ring 12, a pulling force may be applied to the end of the limiting member 2 provided with the limiting portion 211, or a pushing force may be applied to the end of the limiting member 2 away from the limiting portion 211, and this application does not limit this. At the same time, the pulling force or pushing force may be applied manually, or by a driving member such as a push rod, and this application does not limit this.

[0048] In some optional embodiments, at least two first guide portions 121 are provided and are spaced apart along the circumference of the limiting ring 12, and the second guide portion 221 corresponds to the first guide portion 121. At least two first guide portions 121 are provided, which may be two, three or four, and the present application does not limit this. The number of second guide portions 221 is provided corresponding to the number and position of the first guide portions 121. The provision of at least two first guide portions 121 and second guide portions 221 improves the stability of the movement of the limiting member 2 relative to the limiting ring 12. In one example, four first guide portions 121 are provided, and four second guide portions 221 are provided.

[0049] In some optional embodiments, a driving member 4 is further included, and the driving member 4 is located at one end of the limiting member 2 away from the limiting portion 211, and the driving member 4 is used to drive the limiting member 2 to move in the limiting ring 12. The driving member 4 is located at one end of the limiting member 2 away from the limiting portion 211, that is, the driving member 4 provides thrust to the limiting member 2, and the driving member 4 and the limiting member 2 are rotatably connected or abutted, so as to avoid affecting the rotation of the limiting member 2. The driving member 4 can be a driving member such as a push rod, a cylinder, a hydraulic cylinder, etc. that can push the limiting member 2 to move in the limiting ring 12, and this application does not limit it.

[0050] Reference Figure 2-Figure 5 In some optional embodiments, the driving member 4 includes a first driving block 41, a second driving block 42 and a push rod 43. The first driving block 41 is rotatably connected to the end of the limiting member 2 away from the limiting portion 211, and the first driving block 41 is also provided with a first inclined surface 411; the second driving block 42 is provided with a second inclined surface 421, and the second inclined surface 421 is in contact with the first inclined surface 411; the push rod 43 is connected to the second driving block 42, and the push rod 43 is used to push the second driving block 42 to move toward or away from the first driving block 41, so that the first driving block 41 moves toward or away from the limiting portion 211.

[0051] The first drive block 41 is rotatably connected to the end of the limiter 2 away from the limiter 211. The present application does not restrict the rotatable connection between the first drive block 41 and the limiter 2. The rotatable connection can be achieved through the cooperation of the rotation groove and the rotation block, or through other forms. The first drive block 41 and the limiter 2 can rotate with each other, that is, the first drive block 41 does not affect the rotation of the limiter 2 in the limiter ring 12. The first drive block 41 is provided with a first inclined surface 411, that is, the first drive block 41 is provided with a large end and a small end, and the large end of the first drive block 41 is rotatably connected to the limiter 2.

[0052] The second driving block 42 is provided with a second inclined surface 421, that is, the second driving block 42 is provided with a large end and a small end, the small end of the second driving block 42 faces the limiting member 2, and the second inclined surface 421 is in contact with the first inclined surface 411. The second driving block 42 is also connected to the push rod 43. When the push rod 43 pushes the second driving block 42 to move, the second driving block 42 moves toward the first driving block 41. Since the first inclined surface 411 and the second inclined surface 421 are in contact with each other, the second driving block 42 drives the first driving block 41 to have a driving force to move along the axial direction of the limiting member 2, that is, the limiting member 2 is driven to move in the limiting ring 12 through the cooperation of the first guide portion 121 and the second guide portion 221, thereby completing the rotation of the limiting member 2.

[0053] The setting of the first driving block 41 and the second driving block 42 can change the force direction of the push rod 43 from the axial force along the limit member 2 to the radial force along the limit member 2, thereby changing the length direction of the push rod 43, so that the length direction of the push rod 43 is changed from extending along the height direction of the frame 1 to extending along the length or width direction of the frame 1, thereby reducing the volume of the frame assembly and making it more convenient to use the present application.

[0054] In some optional embodiments, a first elastic member 5 is provided between the limit ring 12 and the limit member 2, and the first elastic member 5 is elastically deformed along the extension direction of the central axis of the limit member 2. Among them, the first elastic member 5 can be an elastic member such as a disc spring and a spring, which is not limited in this application. In one example, the first elastic member 5 is a spring and covers the limit member 2, so as to prevent the first elastic member 5 from being skewed during elastic deformation. One end of the first elastic member 5 is connected to the limit ring 12, which can be connected by bonding, plugging, abutting, etc., which is not limited in this application. The other end of the first elastic member 5 is connected to the end of the limit member 2 away from the limit portion 211, which can also be connected by bonding, plugging, abutting, etc., which is not limited in this application. The end of the limit member 2 away from the limit portion 211 is also provided with a chassis to facilitate the connection of the first elastic member 5.

[0055] During operation, when the limit member 2 is forced to move toward the limit portion 211, the first elastic member 5 is compressed. When the thrust or pull of the limit member 2 is removed, the first elastic member 5 returns to its original position, driving the limit member 2 to move away from the limit portion 211, thereby eliminating the need for the operator to manually or through a driving member to operate the return of the limit member 2, thereby improving the convenience of operation.

[0056] Reference Figure 1 and Figure 8 , Figure 8 The structure diagram of the connecting frame, the driving member and the limiting member provided in the embodiment of the present application is shown.

[0057] In some optional embodiments, a plurality of bearing slots 11 are provided, a plurality of limit members 2, a plurality of driving members 4 and a plurality of first elastic members 5 are provided, and a plurality of driving members 4 are connected by a connecting frame 6. The frame 1 is provided with a plurality of bearing slots 11, and the plurality of bearing slots 11 are arranged at intervals along the length direction and the width direction of the frame 1. The provision of a plurality of bearing slots 11 facilitates the simultaneous carrying of a plurality of battery cells 3, thereby improving the processing speed of the battery cells 3. In order to limit and fix a plurality of battery cells 3, a plurality of limit members 2, a plurality of driving members 4 and a first elastic member 5 are also provided. Each bearing slot 11 corresponds to at least two limit members 2 to ensure the limitation of the battery cells 3.

[0058] In order to facilitate the operator to control the rotation of multiple limit members 2 at the same time, a connecting frame 6 is provided, and the connecting frame 6 connects multiple driving members 4. The connecting frame 6 can be connected to multiple first driving blocks 41, multiple second driving blocks 42, and multiple push rods 43. The present application does not limit the connection position of the connecting frame 6 and the driving member 4. In one example, the connecting frame 6 is connected to multiple second driving blocks 42 and multiple push rods 43. If the operator wants to drive the limit member 2 to rotate, the operator can control the connecting frame 6 to control the movement of multiple driving members 4 at the same time.

[0059] In some optional embodiments, a push plate 61 is provided at one end of the connecting frame 6, and a second elastic member 62 is connected to the other end. The end of the second elastic member 62 away from the connecting frame 6 is connected to the frame 1, and the second elastic member 62 elastically deforms along the moving direction of the first driving block 41.

[0060] A push plate 61 is provided at one end of the connecting frame 6. The operator can push or pull the push plate 61 to apply force to the connecting frame 6, and then apply force to the push rod 43. A second elastic member 62 is provided at one end of the connecting frame 6 away from the push plate 61. The second elastic member 62 is connected to the frame 1 at one end away from the connecting frame 6. The second elastic member 62 can be an elastic member such as a spring or a disc spring, and this application does not limit it. The second elastic member 62 elastically deforms along the moving direction of the first drive block 41. The setting of the second elastic member 62 can enable the connecting frame 6 to drive the drive member 4 to return to its original position without the need for additional operation by the operator, thereby improving the convenience of this application. Among them, a plurality of second elastic members 62 are provided and are arranged at intervals along the length of the connecting frame 6, thereby increasing the driving force for returning the connecting frame 6.

[0061] When in use, the operator applies force to the push plate 61, the push plate 61 drives the connecting frame 6 to move, the connecting frame 6 drives the push rod 43 to move, the push rod 43 drives the second drive block 42 to move toward the first drive block 41, so that the first drive block 41 moves toward the limit portion 211, and the second elastic member 62 is in a compressed state. When the force applied to the push plate 61 is removed, the second elastic member 62 returns to its original position, the second elastic member 62 drives the connecting frame 6 to move, the connecting frame 6 drives the push rod 43 to move, the push rod 43 drives the second drive block 42 to move away from the first drive block 41, so that the first drive block 41 moves away from the limit portion 211.

[0062] In some optional embodiments, the limit member 2 includes a main body 22 and a limit head 21 that are detachably connected, the main body 22 is rotatably connected to the frame 1, and the limit head 21 is correspondingly provided with one or at least two limit parts 211. The limit member 2 with at least two limit parts 211 is located between at least two bearing grooves 11.

[0063] The main body 22 and the limit head 21 are detachably connected, so that the main body 22 can replace the limit head 21. The connection method can be bolted or threaded. The present application does not limit the connection method between the main body 22 and the limit head 21. The limit head 21 can be provided with one limit portion 211, or two limit portions 211 or other number of limit portions 211. In one example, part of the limit head 21 is provided with one limit portion 211, and part of the limit head 21 is provided with two limit portions 211, and the two limit portions 211 are symmetrical along the center of the limit head 21. When the limiting member 2 is only located on the circumferential side of one loading slot 11, at this time, it is only necessary to set a limiting member 2 with a limiting portion 211 on the circumferential side of the loading slot 11; when the limiting member 2 is located on the circumferential sides of two loading slots 11, it is necessary to set a limiting member 2 with two limiting portions 211 between the two loading slots 11. The limiting member 2 with two limiting portions 211 can extend into the two loading slots 11 at the same time to limit the battery cell 3, and can also be located on the circumferential sides of the two loading slots 11 at the same time without affecting the insertion of the battery cell 3.

[0064] Reference Figure 1-Figure 8 , the present application also includes a coating device, including a frame assembly as described in any of the above items. The frame assembly is used to carry the battery cell 3, and the frame assembly includes a frame 1 and a stopper 2. The frame 1 is provided with a bearing slot 11 for carrying the battery cell 3; the stopper 2 is located on the peripheral side of the bearing slot 11 and is rotatably connected to the frame 1, and the stopper 2 is provided with a stopper 211 extending from the peripheral side of the stopper 2. The stopper 2 rotates to drive the stopper 2 to rotate, and the stopper 2 switches between a first state and a second state; in the first state, one end of the stopper 211 away from the stopper 2 is located on the peripheral side of the bearing slot 11, so as to facilitate placing the battery cell 3 in the bearing slot 11 or detaching from the bearing slot 11; in the second state, one end of the stopper 211 away from the stopper 2 extends into the bearing slot 11 to prevent the battery cell 3 from falling off from the bearing slot 11.

[0065] The present application sets a limit member 2 at the frame 1, and the state of the limit member 2 can be set according to different situations, so that when assembling or discharging the battery cell 3, the limit member 2 does not block the supporting groove 11. After the assembly is completed, the limit member 2 extends into the supporting groove 11 to block the battery cell 3, which can effectively prevent the battery cell 3 from falling when the frame 1 is placed vertically in the HWCVD, reduce the generation of fragments, and through effective limiting, the battery cell 3 can be made to fit more tightly in the supporting groove 11, effectively isolating the generation of the plating bypass phenomenon, improving production efficiency, and increasing product yield.

[0066] The technical solution provided by this embodiment is described below in conjunction with specific application scenarios.

[0067] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 , it is described as an example that when the limiting member 2 moves upward and rotates so that the limiting portion 211 is located around the bearing groove 11, and when the limiting member 2 moves downward and rotates so that the limiting portion 211 extends into the bearing groove 11.

[0068] When the battery cell 3 needs to be assembled or discharged, in the first state, the operator applies force to the push plate 61, the push plate 61 drives the connecting frame 6 to move, the connecting frame 6 drives the push rod 43 to move, the push rod 43 drives the second driving block 42 to move toward the first driving block 41, so that the first driving block 41 moves toward the limiting portion 211, at this time, the second elastic member 62 is in a compressed state. The first driving block 41 drives the limiting member 2 to move in the limiting ring 12, and then the limiting member 2 rotates while completing the upward movement, so that the limiting portion 211 is located on the peripheral side of the bearing slot 11, so as to facilitate the assembly or discharge of the battery cell 3, at this time, the first elastic member 5 is in a compressed state.

[0069] When the battery cell 3 is assembled and in the second state, the force on the push plate 61 is removed, the second elastic member 62 returns to its position, the second elastic member 62 drives the connecting frame 6 to move, the connecting frame 6 drives the push rod 43 to move, the push rod 43 drives the second drive block 42 to move away from the first drive block 41, so that the first drive block 41 moves away from the limiting portion 211, the first elastic member 5 also returns to its position, driving the limiting portion 211 to move downward and rotate at the same time, so that the limiting portion 211 is located in the supporting groove 11, limiting the battery cell 3 to prevent the battery cell 3 from falling off from the supporting groove 11.

[0070] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
