Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a glue rolling activation mechanism. Background Art

[0002] During the production of digital batteries, PSA tape (pressure-sensitive adhesive) needs to be attached to the battery cells to prevent relative displacement or even separation between the battery cells and the PSA tape during subsequent transportation. The PSA tape must be partially pre-activated when applying the PSA tape.

[0003] The traditional activation method is to press the PSA tape and the battery cell vertically by pressing the rubber block upward. During the pressing process, the rubber block pre-activates the entire area of the PSA to be activated. Affected by the flatness of the rubber block and the battery cell surface, only some areas can be effectively pressed and activated. It can neither achieve the expected activation effect nor avoid the risk of relative displacement or even separation between the battery cell and the PSA tape during subsequent transportation. In addition, the traditional activation method is to use dual power in the vertical and lateral directions to achieve roller glue activation, but dual-power roller glue activation will increase the equipment's action response time and cannot meet the line laying requirements of some scenarios.

[0046] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0047] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like used in the present invention to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0048] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0049] Furthermore, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0050] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0052] like Figure 1 As shown, this embodiment provides a rubber rolling activation mechanism having a first direction X and a second direction Y intersecting each other, with the first direction X and the second direction Y being arranged at an acute angle. The rubber rolling activation mechanism includes a power output module 100 and a rubber rolling activation module 200. The rubber rolling activation module 200 is disposed at the output end of the power output module 100. The power output module 100 can drive the rubber rolling activation module 200 to move along the first direction X.

[0053] It should be noted that the glue roller activation module 200 is usually pressed upward to press the PSA tape onto the battery cell when in use. Therefore, in order to facilitate the description of this embodiment and simplify the description, the term "moving along the first direction" in this embodiment refers to upward movement in the vertical direction, but it does not indicate or imply that the glue roller activation mechanism of this embodiment must have a specific orientation, be constructed and operated in a specific orientation, and it should not be understood as a limitation on the present invention.

[0054] In a preferred embodiment, the power output module 100 of this embodiment is preferably a cylinder, that is, the rubber roller activation module 200 is arranged at the piston end of the cylinder; in other embodiments, the power output module 100 can also be other power mechanisms that can realize the movement of the rubber roller activation module 200 in the first direction X, such as a cam mechanism, a worm gear mechanism, an oil cylinder, etc., and therefore it cannot be understood as a limitation of the present invention.

[0055] In some embodiments, the number of power output modules 100 is one, that is, one power output module 100 alone provides power for the roller glue activation module 200 to move in the first direction X, and the action is correspondingly rapid; and the use of a single power output module 100 can reduce the occupied volume of the roller glue activation mechanism, which can meet the line laying requirements of most scenarios.

[0056] In a specific embodiment, Figures 1-6 As shown, the rubber rolling activation module 200 includes a support assembly 210, a rubber rolling assembly 220, a guide assembly 230 and an elastic activation assembly 240; the support assembly 210 is connected to the output end of the power output module 100 so as to be movable along the first direction X, the guide assembly 230 is mounted on the support assembly 210 and extends along the second direction Y, the rubber rolling assembly 220 is connected to the guide assembly 230 and extends along the first direction X, the elastic activation assembly 240 is mounted on the support assembly 210 along the second direction Y, the elastic activation assembly 240 is connected to the guide assembly 230, and the elastic activation assembly 240 can drive the rubber rolling assembly 220 to move along the second direction Y, that is, the elastic activation assembly 240 can provide a certain pre-tightening force for the rubber rolling assembly 220, so that the rubber rolling assembly 220 can move along the second direction Y of the guide assembly 230, and the rubber rolling assembly 220 can flexibly pre-activate the PSA tape part according to the flatness of the battery cell surface to ensure that the expected activation effect is achieved, while avoiding the risk of relative displacement or even separation between the battery cell and the PSA tape during subsequent transportation.

[0057] It should be understood that when the power output module 100 drives the rubber roller assembly 220 to press the PSA tape and the battery cell along the first direction X, the rubber roller assembly 220 will be moved along the second direction Y along the guide assembly 230 due to the reaction force of the PSA tape and the battery cell, and the elastic activation assembly 240 ensures that the rubber roller assembly 220 is always in contact with the PSA tape and the battery cell.

[0058] In addition, after the rubber rolling assembly 220 and the PSA tape come into contact with the battery cell, the elastic activation assembly 240 is set to enable the rubber rolling assembly 220 to continue to press upward in the first direction X and simultaneously perform lateral (horizontal) rubber rolling activation, without the need to use dual power in the vertical and lateral directions to achieve the rubber rolling activation action, thereby reducing the action response time.

[0059] In some embodiments, please combine Figure 3-Figure 6 To understand, the support assembly 210 includes a base 211 and a guide rail support block 212; the base 211 is connected to the output end of the power output module 100, the power output module 100 can drive the base 211 to move along the first direction X, the elastic activation assembly 240 is installed on the base 211 along the second direction Y, the guide rail support block 212 is connected to the base 211, the guide rail support block 212 is provided with a first inclined surface 2121 extending along the second direction Y, and the guide assembly 230 is provided on the first inclined surface 2121 along the second direction Y.

[0060] It should be noted that, in some embodiments, since there are multiple PSA strips between the PSA tape and the battery cell that need to be pressed together, the number of guide rail support blocks 212 can be multiple, and they are arranged on the base 211 in an intermittent manner. Each guide rail support block 212 is provided with a guide component 230 and a rolling glue component 220, and the number of elastic activation components 240 is multiple, and they correspond one-to-one to the guide components 230 respectively; in other embodiments, the guide rail support block 212 can also be an integral structure, and multiple guide components 230 are arranged in parallel on the guide rail support block 212, and a rolling glue component 220 is installed on each guide component 230. The number of elastic activation components 240 is multiple, and they correspond one-to-one to the guide components 230 respectively.

[0061] In some embodiments, in order to facilitate the assembly of the guide component 230 and the elastic activation component 240 and to reduce the volume of the roller activation mechanism, a first step surface 2111 and a second step surface 2112 are provided on the side of the base 211 away from the power output module 100, the guide rail support block 212 is provided on the first step surface 2111, the elastic activation component 240 is provided on the second step surface 2112, and the first inclined surface 2121 forms an acute angle β with the first step surface 2111.

[0062] In some embodiments, the acute angle β satisfies: 40°≤β≤60°, preferably the acute angle β=50°.

[0063] In the above embodiment, since the rubber rolling assembly 220 exerts pressure on the PSA tape and the battery cell, in order to ensure that the elastic activation assembly 240 can always provide a pre-tightening force in the second direction Y to the guide assembly 230, the height of the plane where the first step surface 2111 is located in the first direction X is limited to be higher than the height of the plane where the second step surface 2112 is located, so that the elastic activation assembly 240 provides the guide assembly 230 with a pre-tightening force in the second direction Y, so as to ensure that the rubber rolling assembly 220 performs lateral (horizontal direction) rubber rolling activation synchronously during the continued upward pressure process, without the need to use dual power in the vertical and lateral directions to realize the rubber rolling activation action, thereby reducing the action response time.

[0064] In some embodiments, in order to prevent the guide assembly 230 from derailing, a positioning block 213 is provided at the end of the guide rail support block 212 away from the base 211. The positioning block 213 is placed on the end of the first inclined surface 2121 away from the elastic activation assembly 240. The positioning block 213 is used to limit the guide assembly 230 in the second direction Y to limit the effective stroke of the guide assembly 230 in the second direction Y.

[0065] In some embodiments, the guide assembly 230 includes a linear guide rail 233, a guide slider 231 and a mounting seat 232; the linear guide rail 233 is provided on the first inclined surface 2121 and extends along the second direction Y, the guide slider 231 is slidably connected to the linear guide rail 233, the mounting seat 232 is connected to the guide slider 231, the rubber rolling assembly 220 is connected to the mounting seat 232, and the elastic activation assembly 240 is connected to the mounting seat 232; in this way, the elastic activation assembly 240 can apply an elastic force in the second direction Y to the mounting seat 232, and when the rubber rolling assembly 220 presses on the PSA tape and the battery cell, the rubber rolling assembly As the component 220 continues to be pressed upward, the PSA tape and the battery cell apply a reaction force opposite to the first direction X to the rubber rolling assembly 220. After the component force of the reaction force overcomes the elastic force of the elastic activation assembly 240, the mounting seat 232 moves in the second direction Y along the linear guide rail 233. As the rubber rolling assembly 220 continues to be pressed upward, the rubber rolling assembly 220 moves a certain distance in the transverse (horizontal) direction, thereby synchronously performing transverse (horizontal) rubber rolling activation on the PSA tape and the battery cell, without using dual power in the vertical and lateral directions to realize the rubber rolling activation action, thereby reducing the action response time.

[0066] In some embodiments, the elastic activation component 240 includes a limit block 241, a limit rod 242 and a compression spring 243; the limit block 241 is provided on the base 211, specifically on the second step surface 2112, the limit block 241 is provided with a second inclined surface 2411, the plane where the second inclined surface 2411 is located intersects with the plane where the first inclined surface 2121 is located, the limit rod 242 is movably installed on the limit block 241 along the second direction Y, one end of the limit rod 242 is connected to the mounting seat 232, the compression spring 243 is sleeved on the limit rod 242, and the two ends of the compression spring 243 are respectively in contact with the limit block 241 and the mounting seat 232. Under the action of the limit block 241, the limit rod 2 42 can only move along the second direction Y. Therefore, the limit rod 242 is placed on the same plane after being connected to the mounting seat 232 to avoid interference in movement after the limit rod 242 is connected to the mounting seat 232. In addition, the two ends of the compression spring 243 are respectively in contact with the limit block 241 and the mounting seat 232, so that the compression spring 243 always provides a pre-tightening elastic force to the mounting seat 232, so that the mounting seat 232 always has a tendency to move away from the limit block 241, so as to ensure that the rubber rolling assembly 220 performs lateral (horizontal direction) rubber rolling activation synchronously during the continued upward pressing process, without the need to use dual power in the vertical and lateral directions to realize the rubber rolling activation action, thereby reducing the action response time.

[0067] In some embodiments, the second inclined surface 2411 and the second step surface 2112 form an acute angle θ, wherein the acute angle θ satisfies: θ+β=90°, and when the acute angle β is preferably 50°, the acute angle θ is preferably 40°.

[0068] In some embodiments, the plane where the first inclined surface 2121 is located is perpendicular to the plane where the second inclined surface 2411 is located, thereby facilitating the design and installation of the guide assembly 230 and the elastic activation assembly 240, reducing the difficulty of processing and assembly, and at the same time enabling the elastic force of the compression spring 243 to act entirely on the mounting seat 232 and the limit block 241.

[0069] In some embodiments, the rubber rolling assembly 220 includes a support 221 and a rubber-wrapped roller 222; wherein, the support 221 is fixed to one end of the mounting seat 232 away from the elastic activation assembly 240, and the rubber-wrapped roller 222 is rotatably mounted on the support 221; to ensure that the rubber-wrapped roller 222 can exert positive pressure on the PSA tape and the battery cell, the support 221 is connected to the mounting seat 232 in a vertical direction, and the compression spring 243 provides a vertical component of force so that the rubber-wrapped roller 222 exerts a positive pressure activation effect on the PSA tape.

[0070] In other embodiments, the rubber rolling assembly 220 also includes a fastener 223, which is detachably connected to the support 221, and the rubber-coated roller 222 is installed between the fastener 223 and the support 221; by providing a detachable fastener 223, the rubber-coated roller 222 can be disassembled, replaced or cleaned. At the same time, rubber-coated rollers 222 of different lengths can be selected for PSA tapes of different sizes to ensure that the rubber-coated roller 222 can fully roll and activate the PSA tape, thereby improving the expected activation effect.

[0071] The working process of this utility model is as follows: Figures 1-6 As shown, the power output module 100 starts the lifting and rolling rubber activation module 200 to move as a whole along the first direction X, so that the rubber roller 222 rises to contact the PSA tape and the battery cell. The PSA tape and the battery cell exert a reaction force on the rubber roller 222 opposite to the first direction X. Driven by the reaction force, the rubber roller 222 and the mounting seat 232 retreat along the linear guide 233 in the direction opposite to the second direction Y. The compression spring 243 provides an elastic force to the mounting seat 232, which is vertical. The longitudinal force causes the rubber-wrapped roller 222 to activate the PSA strip under pressure. When the power output module 100 is still lifted upward in the first direction X, the rubber-wrapped roller 222 is displaced laterally to achieve rolling of the PSA strip. After the rubber rolling is completed, the power output module 100 drives the rubber rolling activation module 200 to descend, and the rubber-wrapped roller 222 is separated from the PSA tape and the battery cell. The rubber-wrapped roller 222 moves and resets in the second direction Y under the elastic force of the compression spring 243, waiting for the next rubber rolling activation operation.

[0072] In summary, the embodiment of the present invention provides a rubber rolling activation mechanism, which enables the rubber rolling assembly 220 to move along the inclined direction by obliquely setting the guide assembly 230 on the support assembly 210, and the elastic activation assembly 240 can provide a certain pre-tightening force for the rubber rolling assembly 220, so that the rubber rolling assembly 220 can flexibly pre-activate the PSA rubber strip part according to the flatness of the battery cell surface, ensuring that the expected activation effect is achieved, and at the same time avoiding the risk of relative displacement or even separation between the battery cell and the PSA tape during subsequent transportation; in addition, the provision of the elastic activation assembly 240 can enable the rubber rolling assembly 220 to synchronously perform lateral rubber rolling activation during the rising process, without the need to use dual power in the vertical and lateral directions to realize the rubber rolling activation action, thereby reducing the action response time, and the use of a single power output module 100 can meet the line laying requirements of most scenarios.
