DETAILED DESCRIPTION
[0026] This application is based on the inventor's discovery and understanding of the following facts and problems:
[0027] The hemming wheel in the related art has a fixed size of hemming groove, which makes it difficult to adapt to battery cells of different specifications and different hemming requirements.
[0028] Specifically, if the width of the hemming groove is too wide relative to the thickness of the battery cell, it is difficult for the battery cell to be accurately centered in the hemming groove, which can easily lead to inconsistent glue widths on both sides. If the depth of the hemming groove is too shallow relative to the required hemming width of the battery cell, it is difficult to achieve the required hemming width. If different hemming wheels are replaced for different battery cells and different hemming requirements, the radial runout and eccentricity of the hemming wheel need to be tested after reinstallation. If the test does not meet the standard, it needs to be reinstalled, which is time-consuming and laborious.
[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.
[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] The following describes an edge wrapping wheel 1 according to an embodiment of the utility model with reference to the accompanying drawings.
[0033] like Figure 1-Figure 4 As shown, the hemming wheel 1 according to the embodiment of the utility model includes a base 10, an overflow wall 20, an hemming cover 30, an upper depth adjustment ring 40 and a lower depth adjustment ring 50 (the up and down directions are shown by the arrows in the figure and are only for the convenience of expression, not for limiting the actual setting direction).
[0034] The overflow glue wall 20 extends along the circumference of the base 10, and the overflow glue wall 20 is provided with an overflow glue hole 21. The edge cover 30 is raised and lowered and is provided on the overflow glue wall 20. The upper depth adjustment ring 40 is detachable and the radial thickness is selectively provided on the edge cover 30. The lower depth adjustment ring 50 is detachable and the radial thickness is selectively provided on the base 10. The upper depth adjustment ring 40, the lower depth adjustment ring 50 and the overflow glue wall 20 jointly define a glue encapsulation groove, and at least a portion of the overflow glue hole 21 is connected to the glue encapsulation groove.
[0035] Specifically, the edge cover 30 covers at least a portion of the overflow glue wall 20. The lower end surface of the upper depth adjustment ring 40, the upper end surface of the lower depth adjustment ring 50 and the outer peripheral surface of the overflow glue wall 20 together define a glue encapsulation groove. In some embodiments, there are multiple overflow glue holes 21 arranged in an array on the overflow glue wall 20, and the edge cover 30 covers the upper end of the overflow glue wall 20 and covers a portion of the peripheral surface of the overflow glue wall 20 from top to bottom and covers a portion of the multiple overflow glue holes 21. The edge cover 30 covers the overflow glue holes 21 other than the glue encapsulation groove.
[0036] It should be understood here that "radial thickness can be selectively installed" refers to the radial thickness of the upper depth adjustment ring 40 and the lower depth adjustment ring 50 that can be selectively installed. For example, multiple upper depth adjustment rings 40 with different radial thicknesses and multiple lower depth adjustment rings 50 with different radial thicknesses can be prepared, and the upper depth adjustment rings 40 and the lower depth adjustment rings 50 with corresponding radial thicknesses are selected according to the required rubber lagging width and installed on the edge cover 30 and the base 10.
[0037] Before hemming, the hemming cover 30 is raised or lowered according to the thickness of the battery cell to be hemmed to adjust the distance between the upper depth adjustment ring 40 and the lower depth adjustment ring 50, thereby adjusting the width of the hemming groove. According to the required hemming width, the upper depth adjustment ring 40 and the lower depth adjustment ring 50 of the corresponding radial thickness are selected and installed on the hemming cover 30 and the base 10, thereby adjusting the depth of the hemming groove.
[0038] During the hemming process, the edge of the battery cell is fitted into the hemming groove, and the hemming glue is injected into the overflow glue wall 20. The hemming glue enters the hemming groove from the overflow glue hole 21 to hem the battery cell passing through the hemming groove.
[0039] According to the hemming wheel 1 of the embodiment of the utility model, an upper depth adjustment ring 40 and a lower depth adjustment ring 50 are provided so that the upper depth adjustment ring 40 and the lower depth adjustment ring 50 are removable and the radial thickness can be selectively installed. Compared with the hemming wheel with a fixed groove depth in the related art, the depth of the hemming groove can be adjusted by selecting upper depth adjustment rings 40 and lower depth adjustment rings 50 with different radial thicknesses, thereby facilitating meeting different hemming width requirements and having stronger applicability.
[0040] In addition, by providing an edge wrapping cover 30 and arranging an upper depth adjustment ring 40 on the edge wrapping cover 30, the edge wrapping cover 30 can be raised and lowered to cover the glue overflow wall 20. Compared with the edge wrapping wheel with a fixed groove width in the related art, the width of the edge wrapping groove can be adjusted by raising and lowering the edge wrapping cover 30, thereby facilitating the edge wrapping requirements of battery cells of different thicknesses, having stronger applicability, and facilitating the placement of the battery cell in the center of the edge wrapping groove, thereby facilitating the consistency of the glue wrapping width on both sides of the battery cell, and facilitating the glue wrapping effect.
[0041] In addition, since the depth of the hemming groove of the hemming wheel 1 can be adjusted by disassembling and assembling the upper depth adjustment ring 40 and the lower depth adjustment ring 50, and the groove width can be adjusted by raising and lowering the hemming cover 30, compared with the hemming wheel in the related art, there is no need to disassemble and assemble the hemming wheel 1 as a whole, and there is no need to retest the radial runout and eccentricity, and the adjustment operation is more convenient, saving time and effort.
[0042] Therefore, the hemming wheel 1 according to the embodiment of the utility model has the advantages of strong applicability, reliable hemming effect, and convenient operation.
[0043] The following describes an edge wrapping wheel 1 according to a specific embodiment of the utility model with reference to the accompanying drawings.
[0044] In some specific embodiments of the present invention, Figure 1-Figure 4 As shown, the hemming wheel 1 according to the embodiment of the utility model includes a base 10 , an overflow glue wall 20 , an hemming cover 30 , an upper depth adjustment ring 40 and a lower depth adjustment ring 50 .
[0045] Optionally, the radial cross-sectional shape of the upper depth adjustment ring 40 can be selectively installed on the edge cover 30, and the radial cross-sectional shape of the lower depth adjustment ring 50 can be selectively installed on the base 10. It should be understood here that "the radial cross-sectional shape can be selectively installed" refers to the radial cross-sectional shapes of the upper depth adjustment ring 40 and the lower depth adjustment ring 50 that can be selectively installed. For example, multiple upper depth adjustment rings 40 with different radial cross-sectional shapes and multiple lower depth adjustment rings 50 with different radial cross-sectional shapes can be prepared, which can facilitate the formation of rubber-coating grooves with different radial cross-sections, thereby testing the effects of rubber-coating grooves of different shapes on the rubber-coating effect, and facilitating the best rubber-coating effect by adjusting the shape of the rubber-coating groove.
[0046] Specifically, Figure 1 and Figure 2 As shown, the hemming wheel 1 also includes a bottom plate 60, the base 10 is rotatably disposed on the bottom plate 60, and the overflow glue wall 20 is connected to the base 10 and rotates with the base 10. Specifically, the lower surface of the base 10 has a positioning protrusion, and the upper surface of the bottom plate 60 has a positioning groove, and the positioning protrusion is rotatably engaged in the positioning groove. The lower end surface of the overflow glue wall 20 is connected to the upper end surface of the base 10 through a fastener. In this way, the overflow glue wall 20 can be driven to rotate by rotating the base 10, which is convenient for realizing the relative movement of the hemming groove and the battery cell, and is convenient for improving the uniformity of the hemming. In addition, the arrangement of the bottom plate 60 can facilitate the arrangement of other structures, for example, the driving device can be arranged on the bottom plate 60.
[0047] More specifically, Figure 1 and Figure 2As shown, the hemming wheel 1 further includes a rotation drive device 70 and a lifting drive device 80. The rotation drive device 70 is connected to the base 10 to drive the base 10 to rotate, and the lifting drive device 80 is arranged on the bottom plate 60 and connected to the hemming cover 30 to drive the hemming cover 30 to rise and fall. Specifically, the rotation drive device 70 is a servo motor and the motor shaft is connected to the base 10 through a threaded fastener, and a bearing is provided between the motor shaft and the bottom plate 60. The lifting drive device 80 is a linear motor and is connected to the hemming cover 30 through a connecting rod. In this way, it is convenient to drive the base 10 to rotate, to drive the hemming cover 30 to rise and fall, and feedback control of the rotation speed and the groove width can be achieved by cooperating with the detection device.
[0048] Furthermore, the edge cover 30 and the glue overflow wall 20 can be relatively rotatably matched. Specifically, when the base 10 drives the glue overflow wall 20 to rotate, the edge cover 30 does not rotate with the glue overflow wall 20. In this way, on the one hand, it is convenient to connect the edge cover 30 with the lifting drive device 80 and the glue injection pipeline, and on the other hand, it is convenient to set a detection device on the edge cover 30.
[0049] Advantageously, the edge cover 30 is provided with a liquid level detection device for detecting the liquid level of the edge glue in the overflow glue wall 20 and / or a viscosity detection device for detecting the viscosity of the edge glue in the overflow glue wall 20. This makes it easy to detect the remaining amount and viscosity of the edge glue, and to replenish the edge glue in time and adjust the viscosity of the edge glue in time.
[0050] More advantageously, a glue injection tube 31 is provided on the edge wrapping cover 30, and a flow detection device for monitoring the injection flow is provided on the glue injection tube 31. In this way, it is convenient to inject glue into the overflow glue wall 20 through the glue injection tube 31, and the injection flow can be detected by the flow detection device, so as to adjust the injection flow in time to ensure the edge wrapping effect.
[0051] Figure 1-Figure 4 The following are some examples of hemming wheels 1 according to the present invention. Figure 4 As shown, the upper depth adjustment ring 40 includes two upper half rings 41, which are detachably connected, and the lower depth adjustment ring 50 includes two lower half rings 51, which are detachably connected. Specifically, the two upper half rings 41 are respectively installed on the edge cover 30 by fasteners, and the two upper half rings 41 abut against each other after installation, and the two lower half rings 51 are respectively installed on the base 10 by fasteners, and the two lower half rings 51 abut against each other after installation. In this way, the upper depth adjustment ring 40 and the lower depth adjustment ring 50 can be easily disassembled and assembled.
[0052] Advantageously, if Figure 1-Figure 4As shown, at least one of the upper depth adjustment ring 40 and the lower depth adjustment ring 50 is provided with a groove width detection device for detecting the axial width of the rubber coating groove. Specifically, the groove width detection device includes a groove width detection receiving device 91 and a groove width detection transmitting device 92, one of which is provided on the upper depth adjustment ring 40 and the other is provided on the lower depth adjustment ring 50. The groove width detection device is electrically connected to the lifting drive device 80. In this way, the width of the rubber coating groove can be detected, which is convenient for feedback adjustment of the width of the rubber coating groove.
[0053] Alternatively, if Figure 1-Figure 3 As shown, a scale 22 is provided on the overflow wall 20. In this way, the width of the glue encapsulation groove can be determined by the scale 22, and the position of the battery cell in the glue encapsulation groove can be checked during the hemming process, so as to confirm whether the battery cell is centered in the glue encapsulation groove. The device can also be used in conjunction with the groove width detection device, for example, by comparing and verifying with the groove height detection sensor to reduce errors and prevent sensor failure.
[0054] More advantageously, if Figure 1-Figure 3 As shown, the bottom plate 60 is provided with a glue collecting groove 61 arranged around the base 10 and a glue discharge groove 62 connecting the glue collecting groove 61 and the edge of the bottom plate 60. In this way, the glue collecting groove 61 can be used to collect the excess edge glue overflowing the glue encapsulation groove, and the glue discharge groove 62 can be used to guide the collected edge glue, so as to facilitate the recycling of the edge glue.
[0055] Specifically, the diameter of the overflow glue hole 21 is preferably 0.4-1.2 mm, and the overflow glue holes 21 are arranged on the overflow glue wall 20 in a plurality of circles spaced apart along the axial direction of the overflow glue wall 20, and each circle includes a plurality of overflow glue holes 21 spaced apart along the circumferential direction of the overflow glue wall 20. Preferably, each circle includes 80-150 overflow glue holes 21. The interval between two adjacent circles in the axial direction of the overflow glue wall 20 is 1-1.5 mm. The depth of the hemming groove is preferably 0.3-1.5 mm.
[0056] Other structures and operations of the hemming wheel 1 according to the embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.
