[0002] For ultra-thin 3C electronic products, the flatness of the battery is crucial to the assembly quality. To ensure the flatness of the battery, a rolling mill is usually used. However, existing battery rolling mills often result in uneven stress on the battery surface during the rolling process, leading to concentrated stress in certain areas and affecting battery lifespan, or even causing damage during the rolling process.

[0003] Therefore, there is an urgent need for a battery rolling bonding fixture to solve the above problems. Utility Model Content

[0008] The rolling assembly is disposed on the side of the pressure assembly facing the receiving groove. The rolling assembly is rotatably connected to the pressure assembly about the second direction. The rolling assembly has a circumferential rolling surface, which can rotate relative to the pressure assembly about a third direction to roll the battery to be rolled in the receiving groove.

[0009] As an improvement to the above technical solution, the rolling assembly includes a rolling roller and a rolling roller connector. The rolling roller connector has a first end and a second end that are disposed opposite to each other along the first direction. The first end of the rolling roller connector is rotatably connected to the end of the pressure assembly facing the receiving groove. The rolling roller is rotatably connected to the second end of the rolling roller connector. The outer circumferential surface of the rolling roller forms the circumferential rolling surface.

[0010] As an improvement to the above technical solution, the rolling roller includes a cylindrical roller and an elastic rubber layer. The cylindrical roller is rotatably connected to the second end of the rolling roller connector. The elastic rubber layer covers the cylindrical roller along the circumference of the cylindrical roller, and the outer circumferential surface of the elastic rubber layer forms the circumferential rolling surface.

[0011] As an improvement to the above technical solution, the pressure assembly includes a guide rod, a weight holder, and a counterweight. The guide rod is disposed on the frame and extends along the first direction and is movable relative to the frame along the first direction. The weight holder is fixedly disposed at the end of the guide rod away from the receiving groove, and the counterweight is disposed on the weight holder.

[0012] As an improvement to the above technical solution, the frame includes a worktable, a mounting bracket, and a product seat, with the product seat fixedly mounted on the worktable; the mounting bracket is fixedly mounted on the worktable, and both the drive assembly and the pressure assembly are mounted on the mounting bracket, with the receiving groove located on the side of the product seat facing the pressure assembly.

[0013] As an improvement to the above technical solution, the product holder includes a first support plate, a second support plate, and a limiting component.

[0014] As an improvement to the above technical solution, the driving component includes a driving member, which includes a cylinder and a first slider connected to the cylinder. The cylinder is fixedly mounted on the mounting bracket. The pressure component is connected to the first slider. The cylinder can drive the first slider to move, thereby driving the pressure component to move along the second direction.

[0015] As an improvement to the above technical solution, the driving component is a cylinder, and the driving assembly further includes a control valve and an air supply line. The control valve is disposed on the worktable, and the air supply line connects the driving component and the control valve. The control valve is used to control the driving component.

[0016] As an improvement to the above technical solution, a guide assembly is also included, which includes a first slide rail, a second slider, and a guide member;

[0017] The first slide rail is fixedly mounted on the mounting bracket and extends along the second direction. The first slide rail and the driving member are spaced apart along the third direction. The second slider is slidably connected to the first slide rail.

[0019] As an improvement to the above technical solution, the pressure assembly further includes a retaining ring, which is disposed on the pressure assembly and located above the guide member. The retaining ring is used to abut against the guide member to limit the position of the pressure assembly relative to the worktable along the first direction.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model discloses a battery rolling bonding fixture. A driving component can drive a pressure component to move along a second direction. The rolling component is disposed on the pressure component, and its circumferential rolling surface can rotate relative to the pressure component about its own axis perpendicular to the second direction. The pressure component applies pressure to the rolling component, allowing the pressure component to roll the battery to be rolled through the circumferential rolling surface of the rolling component. Furthermore, the rolling component can oscillate relative to the pressure component about an axis extending along the second direction, thereby allowing the battery to be rolled to circumferentially roll against the rolling component. When the contact surface is uneven, the rolling assembly can tilt the circumferential rolling surface along a third direction by swinging relative to the pressure assembly. This causes the protrusions on the surface of the battery to be rolled to be flattened towards the edge of the battery closer to the protrusion. Compared to flattening the protrusions on the surface of the battery to be rolled vertically downwards, the method of flattening the protrusions towards the edge of the battery closer to the protrusion in this invention can avoid excessive local stress during the rolling of the battery and make the stress on the battery more uniform during the rolling process. For example, when the protrusion on the surface of the battery to be rolled is close to the left end of the battery along a third direction, when the circumferential rolling surface moves to the protrusion, the rolling assembly swings relative to the pressure assembly under the action of the protrusion, causing the end of the circumferential rolling surface close to the left end of the battery to be rolled to lift up. At this time, the circumferential rolling surface is in a state where the left end is high and the right end is low. When the circumferential rolling surface in this inclined state rolls over the protrusion, it will flatten the protrusion in the direction close to the left end of the battery to be rolled.

[0037] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] like Figures 1-5 As shown, this embodiment provides a battery rolling and bonding fixture, which has two perpendicular directions X, Y, and Z. The first direction X is the height direction of the battery rolling and bonding fixture. The battery rolling and bonding fixture includes a frame 1, a pressure component 2, a drive component 3, and a rolling component 4. The frame 1 is provided with a receiving groove 10 for holding the battery 100 to be rolled. The pressure component 2 is disposed on the side of the receiving groove 10 away from the frame 1. The drive component 3 is disposed on the frame 1 and is used to drive the pressure component 2 to move along the second direction Y. The rolling component 4 is disposed on the side of the pressure component 2 facing the receiving groove 10 and is rotatably connected to the pressure component 2 around the second direction Y. The pressure component 2 is used to apply force to the rolling component 4. The rolling component 4 has a circumferential rolling surface 41, which can rotate relative to the pressure component 2 around the third direction Z to roll the battery 100 to be rolled in the receiving groove 10.

[0042] The length of the circumferential rolling surface 41 along its own axis is equal to or slightly greater than the length of the battery 100 to be rolled in the receiving groove 10 along the third direction Z. In this embodiment, the circumferential rolling surface 41 is greater than the length of the battery 100 to be rolled in the receiving groove 10 along the third direction Z.

[0043] The battery rolling bonding fixture provided in this embodiment has a driving component 3 that can drive the pressure component 2 to move along the second direction Y. The rolling component 4 is disposed on the pressure component 2, and the circumferential rolling surface 41 of the rolling component 4 can rotate relative to the pressure component 2 about its own axis perpendicular to the second direction Y. The pressure component 2 applies pressure to the rolling component 4, so that the pressure component 2 can roll the battery 100 to be rolled through the circumferential rolling surface 41 of the rolling component 4. In addition, the rolling component 4 can swing relative to the pressure component 2 about an axis extending along the second direction Y, so that the battery 100 to be rolled and the circumferential surface of the rolling component 4 can be rolled together. When the surface in contact with the rolling surface 41 is uneven, the rolling assembly 4 can tilt the circumferential rolling surface 41 along the third direction Z by swinging relative to the pressure assembly 2. This causes the protrusion on the surface of the battery 100 to be rolled to be flattened towards the edge of the battery 100 closer to the protrusion. Compared to flattening the protrusion on the surface of the battery 100 vertically downward, the method of flattening the protrusion towards the edge of the battery 100 closer to the protrusion in this embodiment can avoid excessive local force on the battery 100 during rolling, and make the force on the battery 100 during rolling more uniform. For example, when the protrusion on the surface of the battery to be rolled is close to the left end of the battery to be rolled along a third direction, when the circumferential rolling surface 41 moves to the protrusion, under the action of the protrusion, the rolling component 4 swings relative to the pressure component 2, causing the end of the circumferential rolling surface 41 close to the left end of the battery to be rolled to lift up. At this time, the circumferential rolling surface 41 is in a state where the left end is high and the right end is low. When the circumferential rolling surface 41 in this inclined state rolls over the protrusion, it will flatten the protrusion in the direction close to the left end of the battery to be rolled. Similarly, when the protrusion on the surface of the battery to be rolled 100 approaches the right end of the battery to be rolled along a third direction, when the circumferential rolling surface 41 moves to the protrusion, under the action of the protrusion, the rolling assembly 4 swings relative to the pressure assembly 2, causing the end of the circumferential rolling surface 41 near the right end of the battery to be rolled to lift up. At this time, the circumferential rolling surface 41 is in a state where the right end is high and the left end is low. When the circumferential rolling surface 41 in this inclined state rolls over the protrusion, it will flatten the protrusion in the direction of approaching the right end of the battery to be rolled 100.

[0044] Optionally, such as Figure 1 and Figure 5As shown, the rolling assembly 4 includes a rolling roller 42 and a rolling roller connector 43. The rolling roller connector 43 has a first end and a second end that are disposed opposite to each other along a first direction X. The first end of the rolling roller connector 43 is rotatably connected to the end of the pressure assembly 2 facing the receiving groove 10. The rolling roller 42 is rotatably connected to the second end of the rolling roller connector 43. The outer circumferential surface of the rolling roller 42 forms a circumferential rolling surface 41. The rolling assembly 4 can swing relative to the pressure assembly 2 through the rotatable connection between the first end of the rolling roller connector 43 and the bottom end of the pressure assembly 2. The rolling roller 42 can rotate relative to the pressure assembly 2 through the rotatable connection between the second end of the rolling roller connector 43 and the rolling roller connector 43.

[0045] Furthermore, such as Figure 1 and Figure 5 As shown, the rolling roller 42 includes a cylindrical roller 421 and an elastic rubber layer 422. The cylindrical roller 421 is rotatably connected to the second end of the rolling roller connector 43. The elastic rubber layer 422 covers the cylindrical roller 421 circumferentially, and the outer circumferential surface of the elastic rubber layer 422 forms a circumferential rolling surface 41. The elastic rubber layer 422 can undergo elastic deformation. By covering the cylindrical roller 421 with the elastic rubber layer 422, local stress concentration is further avoided in the rolling process due to the unevenness of the surface of the battery 100 to be rolled, thereby improving the uniformity of the force on the battery 100 to be rolled.

[0046] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, the rolling roller 42 and the rolling roller connector 43, and / or the rolling roller connector 43 and the pressure assembly 2, are detachably connected, allowing the rolling roller 42 to be easily replaced. This enables the matching of a suitable rolling roller 42 based on product requirements and DOE (Design of Experiments) verification data. Specifically, different rolling rollers 42 are coated with elastic adhesive layers 422 of different hardness, and the hardness of the elastic adhesive layer 422 suitable for different batteries 100 to be rolled is verified by DOE. Preferably, the rolling roller 42 and the rolling roller connector 43, as well as the rolling roller connector 43 and the pressure assembly 2, are detachably connected. Specifically, in this embodiment, the rolling roller 42 is rotatably connected to the rolling roller connector 43 via a detachable rotating shaft, and the rolling roller connector 43 is rotatably connected to the pressure assembly 2 via a detachable rotating shaft.

[0047] Optionally, such as Figure 1 and Figure 4As shown, the pressure assembly 2 includes a guide rod 21, a weight holder 22, and a counterweight 23. The guide rod 21 is mounted on the frame 1 and extends along a first direction X, and is movable relative to the frame 1 along the first direction X. The weight holder 22 is fixedly mounted on the end of the guide rod 21 away from the receiving groove 10, and the counterweight 23 is mounted on the weight holder 22. The pressure of the pressure assembly 2 is adjusted by changing the weight of the counterweight 23. The weights of the counterweights 23 corresponding to different types of batteries 100 to be rolled are obtained based on data verified by DOE.

[0048] Furthermore, such as Figure 1 and Figure 4 As shown, the pressure assembly 2 also includes a connecting plate 25, which is fixedly connected to the bottom end of each guide rod 21. The connecting plate 25 is provided with a strip hole 251, and the top end of the roller connecting member 43 is inserted into the strip hole 251. The rotating shaft passes through the part of the roller connecting member 43 located in the strip hole 251 and rotates the roller connecting member 43 to the connecting plate 25.

[0049] Optionally, such as Figure 1 and Figure 2 As shown, the frame 1 includes a worktable 11, a mounting bracket 12, and a product base 13, with the product base 13 fixedly mounted on the worktable 11. The mounting bracket 12 is also fixedly mounted on the worktable 11, and both the drive assembly 3 and the pressure assembly 2 are mounted on the mounting bracket 12. A receiving slot 10 is located on the side of the product base 13 facing the pressure assembly 2. By providing the mounting bracket 12 on the worktable 11, the installation of the drive assembly 3 and the pressure assembly 2 is facilitated.

[0050] Optionally, such as Figure 1 and Figure 3 As shown, the product holder 13 includes a first support plate 131, a second support plate 132, and a limiting component 133. The first support plate 131 is fixedly disposed on the side of the worktable 11 facing the pressure component 2, the second support plate 132 is fixedly disposed on the side of the first support plate 131 facing the pressure component 2, the receiving groove 10 is disposed on the side of the second support plate 132 facing the pressure component 2, and the limiting component 133 is disposed on the first support plate 131 to limit the battery 100 to be rolled into the receiving groove 10, so as to prevent the battery 100 to be rolled into the receiving groove 10 from coming out of the receiving groove 10 during the rolling process. The battery rolling and bonding fixture in this embodiment is designed with two product seats 13 for the batteries 100 to be rolled. The receiving groove 10 is designed to ensure the stability of the batteries 100 after they are placed in. The position of the batteries 100 to be rolled is fixed by the product seats 13 to prevent the batteries 100 from moving during the reciprocating rolling process. The first support plate 131 is detachably connected to the worktable 11 by screws. The product seats 13 can be replaced as a whole according to the type of batteries 100 to be rolled.

[0051] Furthermore, such as Figure 1 and Figure 3 As shown, the limiting component 133 includes a stop block 1331, a sliding plate 1332, and a rotating block 1333. The stop block 1331 is fixedly disposed on the first support plate 131. The two stop blocks 1331 are spaced apart along the second direction Y. The first support plate 131 is located between the two stop blocks 1331 and is spaced apart from both stop blocks 1331 along the second direction Y. The slide plate 1332 and the stop block 1331 are arranged in a one-to-one correspondence. The slide plate 1332 is slidably disposed on the first support plate 131 and is located between the corresponding stop block 1331 and the second support plate 132. The slide plate 1332 has a first working position close to the second support plate 132 and a second working position away from the second support plate 132, and can slide between the first working position and the second working position. The side of the slide plate 1332 close to the second support plate 132 is provided with a pressing protrusion 13321 protruding in the direction close to the second support plate 132. When the slide plate 1332 is in the first working position, the pressing protrusion 13321 is at least partially located above the receiving groove 10 to limit the battery 100 to be rolled into the receiving groove 10. When the slide plate 1332 is in the second working position, the projection of the pressing protrusion 13321 along the first direction X is located outside the receiving groove 10. Rotating block 1333 and stop block 1331 are arranged in a one-to-one correspondence. Rotating block 1333 has a fifth end and a sixth end arranged opposite to each other. The fifth end of rotating block 1333 is rotatably disposed on the side of the corresponding stop block 1331 facing the second bearing plate 132. The rotation axis between rotating block 1333 and the corresponding stop block 1331 extends along the second direction Y. Stop block 1331 has a third working position and a fourth working position. When stop block 1331 is in the third working position, slide plate 1332 can slide from the first working position to the second working position. When stop block 1331 is in the fourth working position, the sixth end of rotating block 1333 is clamped between the corresponding slide plate 1332 and the corresponding stop block 1331 so that slide plate 1332 stays in the first working position. In this embodiment, the first support plate 131 is provided with a second slide rail that corresponds one-to-one with the slide plate 1332. The slide plate 1332 is slidably connected to the corresponding second slide rail, thereby realizing the sliding of the slide plate 1332 relative to the first support plate 131.

[0052] Optionally, such as Figure 1 and Figure 2 As shown, the drive assembly 3 includes a drive member 31, which includes a cylinder 311 and a first slider 312 connected to the cylinder 311. The cylinder 311 is fixedly mounted on the mounting bracket 12. The pressure assembly 2 is connected to the first slider 312. The cylinder 311 can drive the first slider 312 to move, thereby driving the pressure assembly 2 to move along the second direction Y. The drive member 31 drives the pressure assembly 2 along the second direction Y.

[0053] Furthermore, such as Figure 1 and Figure 2 As shown, the driving component 31 is a cylinder, and the driving assembly 3 also includes a control valve 32 and a venting pipe. The control valve 32 is mounted on the worktable 11, and the venting pipe connects the driving component 31 and the control valve 32. The control valve 32 is used to control the driving component 31. Controlling the extension and retraction of the cylinder by controlling the opening and closing of the venting pipe is a conventional technique in the art, and the specific control method is not described here. By manually moving the control valve 32, the driving component 31 is controlled to drive the pressure assembly 2 and the rolling assembly 4 to reciprocate in the second direction, achieving multiple rolling of the battery 100 to be rolled. In this embodiment, the driving component 31 is a rodless cylinder, and the control valve 32 is a mechanical control valve. The specific control method of the control valve 32 over the rodless cylinder is common knowledge in the art and is not described here.

[0054] Optionally, such as Figure 1 and Figure 2 As shown, the battery rolling bonding fixture provided in this embodiment also includes a guide assembly 5, which includes a first slide rail 51, a second slider 52, and a guide member 53. The first slide rail 51 is fixedly mounted on the mounting bracket 12 and extends along the second direction Y. The first slide rail 51 and the drive member 31 are spaced apart along the third direction Z. The second slider 52 is slidably connected to the first slide rail 51. The first slide rail 51 and the second slider 52 cooperate with the drive member 31 to guide the pressure assembly 2 along the second direction Y. The guide member 53 has a third end and a fourth end that are arranged opposite each other along the third direction Z. The third end of the guide member 53 is fixedly connected to the first slider 312, and the fourth end is fixedly connected to the second slider 52. The pressure assembly 2 is connected to the guide member 53 and can move with the guide member 53 along the second direction Y, and can move relative to the guide member 53 along the first direction X.

[0055] Furthermore, the guide member 53 includes a support plate 531 and a limiting guide plate 532. One end of the support plate 531 is fixedly connected to the first slider 312, and the other end is fixedly connected to the second slider 52. The limiting guide plate 532 is fixed to the side of the support plate 531 facing away from the worktable 11. The guide rod 21 is slidably disposed on the limiting guide plate 532 and can slide relative to the limiting guide plate 532 along the first direction X. The limiting guide plate 532 serves to guide the guide rod 21. In this embodiment, four guide rods 21 are provided, and the four guide rods 21 are spaced apart.

[0056] Furthermore, such as Figure 1 and Figure 4As shown, the pressure assembly 2 also includes a retaining ring 24, which is disposed on the pressure assembly 2 and located above the guide member 53. The retaining ring 24 abuts against the guide member 53 to limit the position of the pressure assembly 2 relative to the worktable 11 along the first direction X. In this embodiment, the retaining ring 24 is used to limit the lowest position of the pressure assembly 2 relative to the worktable 11. When it is necessary to adjust the lowest position of the guide rod 21, the retaining ring 24 is loosened, and the retaining ring 24 is slid relative to the guide rod 21 as needed. Then, the retaining ring 24 is tightened again to secure it to the guide rod 21. At this time, the height of the guide rod 21 can be limited by the cooperation between the retaining ring 24 and the limiting guide plate 532. The height of the rolling roller 42 is adjusted by the retaining ring 24 so that the battery rolling and bonding fixture can be adapted to the battery 100 and product seat 13 of different thicknesses.

[0057] Optionally, such as Figure 1 and Figure 2 As shown, the guide assembly 5 also includes a stroke limiter 54, which is detachably connected to the first slide rail 51 to limit the movement range of the pressure assembly 2 along the second direction Y. The stroke limiter can be quickly adjusted according to the size of the battery 100 to be rolled, and can be flexibly matched.

[0058] The battery rolling bonding fixture provided in this embodiment can avoid the subjective influence of manual rolling and product defects caused by improper manual operation, thereby improving the yield rate.

[0059] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
