[0050] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0051] The following is based on the attached Figure 1 To Attachment Fig.11 The invention introduces a packaging head and a packaging device provided by the utility model.

[0052] like Figure 1 As shown, in this embodiment, the packaging head includes a first pressing component 1 and a second pressing component 2, and the first pressing component 1 and the second pressing component 2 can be pressed along a preset first direction (such as Figure 1 The two layers of aluminum-plastic film are clamped with a preset pressure and heated to perform packaging according to a preset packaging thickness.

[0053] Specifically, Figures 1 to 3 As shown, in this embodiment, the first pressing component 1 includes a first pressing member 11, a first abutting member 13 and a first stopper 12. The first abutting member 13 is arranged at an adjustable distance from the first pressing member 11 along the Z-axis direction, and has a first abutting surface 130. The first abutting surface 130 can abut against the second pressing component 2 during packaging to adjust the packaging thickness. The first stopper 12 is abutted between the first pressing member 11 and the first abutting member 13. The thickness dimension of the first stopper 12 in the Z-axis direction is along the preset second direction (such as Figure 1 The preset second direction is perpendicular to the preset first direction, and the first limit member 12 is adjustably arranged on the first pressing member 11 along the X-axis direction.

[0054] When using the packaging head, firstly, the preset packaging thickness is obtained according to the size of the battery, the size of the aluminum-plastic film used, and the sealing requirements of the battery. Then, by adjusting the position of the first stopper 12 relative to the first pressing member 11 along the X-axis direction, the distance between the first abutting member 13 and the first pressing member 11 along the Z-axis direction can be changed, thereby changing the actual packaging thickness that can be achieved between the first pressing member 1 and the second pressing member 2 when the first abutting member 13 abuts against the second pressing member 2.

[0055] For example, when the actual package thickness that can be achieved between the first pressing component 1 and the second pressing component 2 is greater than the preset package thickness, the thickness of the first limiting member 12 is changed from large to small (such as Figure 1 By moving the first stopper 12 along the side of the X-axis in the middle of the package (ie, the first contact surface 130 and the first pressing member 11 along the Z-axis direction), the distance between the first abutting surface 130 and the first pressing member 11 along the Z-axis direction is reduced, so that the actual package thickness that can be achieved between the first pressing assembly 1 and the second pressing assembly 2 can be reduced. Therefore, by moving the first stopper 12 in the direction from large to small in thickness, the actual package thickness that can be achieved between the first pressing assembly 1 and the second pressing assembly 2 can be reduced to a preset package thickness.

[0056] Similarly, when the actual package thickness that can be achieved between the first pressing component 1 and the second pressing component 2 is less than the preset package thickness, the thickness of the first limiting member 12 is increased from small to large (such as Figure 1 By moving the first stopper 12 along the other side of the X-axis in the middle of the package (ie, the other side of the X-axis in the middle of the package), the distance between the first abutting surface 130 and the first pressing member 11 along the Z-axis direction is increased, so that the actual package thickness that can be achieved between the first pressing assembly 1 and the second pressing assembly 2 can be increased. Therefore, by moving the first stopper 12 in the direction from small to large in thickness, the actual package thickness that can be achieved between the first pressing assembly 1 and the second pressing assembly 2 can be increased to a preset package thickness.

[0057] It should be noted that, in the present invention, "thickness dimension" and "package thickness" are respectively used to refer to the dimensions of parts or gaps along the Z-axis direction. At the same time, the first limiter 12 is disposed between the first pressing member 11 and the first abutting member 13, and the first limiter 12 can be disposed directly between the first pressing member 11 and the first abutting member 13, or the first limiter 12 can be disposed indirectly between the first pressing member 11 and the first abutting member 13 through an intermediate medium, or directly abut one of the first pressing member 11 and the first abutting member 13, and indirectly abut the other.

[0058] Furthermore, the abutment connection between the first abutment surface 130 and the second pressing component 2 can be either a direct abutment connection between the first abutment surface 130 and the second pressing component 2, or an indirect abutment connection between the first abutment surface 130 and the second pressing component 2 through an intermediate medium (the intermediate medium can be a product to be packaged); it can be either only moving the first pressing component 1 so that the first pressing component 1 moves toward the second pressing component 2, or only moving the second pressing component 2 so that the second pressing component 2 moves toward the first pressing component 1. As long as the first stopper 12 can be moved along the X-axis direction to change the distance between the first abutment component 13 and the first pressing component 11 along the Z-axis direction, so that the actual packaging thickness that can be achieved between the first pressing component 1 and the second pressing component 2 changes, it falls within the scope of protection of the present utility model.

[0059] In the packaging head, the first stopper 12 whose thickness dimension is reduced along the X-axis direction is abutted between the first pressing member 11 and the first abutment 13, so that by moving the first stopper 12 along the X-axis direction, the distance between the first abutment 13 and the first pressing member 11 can be changed, so that the actual packaging thickness that can be achieved between the first pressing component 1 and the second pressing component 2 is changed, so that the actual packaging thickness can be quickly and conveniently made the same as the preset packaging thickness, meeting the requirements of battery packaging with different thickness requirements or sealing requirements, avoiding multiple replacement of the packaging head, thereby improving production efficiency, simplifying the production process, and reducing production costs. In addition, compared with directly adjusting the distance between the first abutment 13 and the first pressing member 11 along the Z-axis direction, the distance between the first abutment 13 and the first pressing member 11 can be adjusted more accurately by moving the first stopper 12, reducing the difficulty of adjusting the packaging accuracy, and also conducive to improving the packaging quality and product quality.

[0060] like Figures 4 to 6 As shown, in the present invention, the thickness dimension of the first stopper 12 is reduced along the X-axis direction, and the first stopper 12 can be set as a wedge-shaped member, that is, the first stopper 12 has two opposite surfaces 120, and the distance between the two opposite surfaces 120 in the Z-axis direction gradually decreases along the X-axis direction, so that the first stopper 12 has a reduced thickness dimension. Of course, the two opposite surfaces 120 can be either curved surfaces or flat surfaces, or one is a curved surface and the other is a flat surface, all of which are within the scope of protection of the present invention.

[0061] Specifically, in this embodiment, Figure 5As shown, the first limiting member 12 is a trapezoidal member having a first surface and a second surface opposite to each other, and the distance between the first surface and the second surface gradually decreases. The first surface abuts against the first pressing member 11, and the second surface abuts against the first abutting member 13. Specifically, the first surface can be a plane, and the second surface can be an inclined surface. The first limiting member 12 abuts against the first abutting member 13 and is provided with a first limiting portion 123 and a second limiting portion 124 on one side thereof. The first abutting member 13 is limitedly arranged between the first limiting portion 123 and the second limiting portion 124 along the X-axis direction to prevent the first limiting member 12 and the first abutting member 13 from being separated during the movement of the first limiting member 12.

[0062] like Figure 6 As shown, the first abutment member 13 has an inclined abutment surface, which is opposite to and inclined to the first abutment surface 130. Furthermore, the inclined abutment surface of the first abutment member 13 is adapted to the shape of the inclined second surface of the first limiting member 12. The inclined setting ensures that when the first limiting member 12 moves, the angle of the first abutment surface 130 relative to the horizontal plane remains unchanged, thereby avoiding the phenomenon of poor uniformity of the packaging thickness at the first abutment surface 130 after the first limiting member 12 is moved.

[0063] like Figure 5 , Figure 7 and Figure 8 As shown, the first pressing member 11 is provided with a limit member guide protrusion 112, and the first limit member 12 is provided with a limit member guide groove 121. The limit member guide protrusion 112 is inserted into the limit member guide groove 121 to slide and connect the first pressing member 11 and the first limit member 12 along the X-axis direction. The length directions of the limit member guide protrusion 112 and the limit member guide groove 121 are both arranged along the X-axis direction to ensure that the first limit member 12 can move along the X-axis direction, and ensure that there is an accurate correspondence between the moving distance of the first limit member 12 along the X-axis direction and the distance between the first abutting member 13 and the first pressing member 11 along the Z-axis direction, so as to facilitate ensuring the adjustment accuracy of the packaging thickness.

[0064] Of course, in some other embodiments, the limiter guide protrusion 112 may be disposed on the first limiter 12 , and the limiter guide groove 121 may be disposed on the first pressing member 11 , which also falls within the scope of protection of the present utility model.

[0065] like Figures 6 to 8As shown, the first pressing member 11 is provided with an abutment member guiding protrusion 113, and the first abutment member 13 is provided with an abutment member guiding groove 131. The abutment member guiding protrusion 113 is inserted into the abutment member guiding groove 131 to slide and connect the first pressing member 11 and the first abutment member 13 along the Z-axis direction. The length directions of the abutment member guiding protrusion 113 and the limiting member guiding groove 121 are both arranged along the Z-axis direction to ensure that the first abutment member 13 can move along the Z-axis direction, and also ensure that there is an accurate correspondence between the moving distance of the first limiting member 12 along the X-axis direction and the distance between the first abutment member 13 and the first pressing member 11 along the Z-axis direction, which is further conducive to ensuring the adjustment accuracy of the packaging thickness.

[0066] Similarly, in some other embodiments, the abutment member guiding protrusion 113 may be provided on the first abutment member 13 , and the abutment member guiding groove 131 may be provided on the first pressing member 11 , which also falls within the scope of protection of the present utility model.

[0067] Preferably, in this embodiment, the position-limiting member guiding groove 121 is a dovetail groove, and the position-limiting member guiding protrusion 112 is a dovetail tenon. When the dovetail tenon is slidably inserted in the dovetail groove, the first position-limiting member 12 and the first pressing member 11 can be limited not only along the length direction of the dovetail groove (i.e., the X-axis direction), but also along the depth direction of the dovetail groove (i.e., the Z-axis direction), which is helpful to prevent the first position-limiting member 12 from being separated from the first pressing member 11.

[0068] like Figure 7 As shown, in this embodiment, the first pressing member 11 is further provided with a first protruding portion 111. During packaging, the first protruding portion 111 can clamp the aluminum-plastic film with the second pressing assembly 2 according to a preset pressure to perform packaging. In this embodiment, the first protruding portion 111 and the first abutting member 13 are arranged along a preset third direction (such as Figure 7 The first protrusion 111 and the first abutment 13 are arranged in a plurality of directions, so that the consistency of the package thickness between the first protrusion 111 and the second pressing assembly 2 at different positions along the X-axis direction can be improved during packaging, and the phenomenon of the package thickness gradually decreasing along the X-axis direction can be avoided, and the packaging quality and product quality can also be improved. The first protrusion 111 can have a built-in heating component, so that when the aluminum-plastic film is clamped between the first protrusion 111 and the second pressing assembly 2, the aluminum-plastic film is heated according to a preset temperature to achieve heat sealing.

[0069] Optionally, along the Y-axis direction, the first abutment member 13 and the first stopper 12 are provided on both sides of the first protrusion 111. During packaging, the first abutment member 13 and the first stopper 12 provided on both sides of the first protrusion 111 are adjusted respectively, which is beneficial to improving the consistency of the packaging thickness between the two sides of the first protrusion 111 and the second pressing assembly 2 along the Y-axis direction, avoiding the phenomenon that the packaging thickness gradually decreases along the Y-axis direction, thereby improving the packaging quality and product quality.

[0070] In this embodiment, the above-mentioned abutment member guide groove 131 is a dovetail groove, which is provided on the first abutment member 13; the above-mentioned abutment member guide protrusion 113 is a dovetail tenon, which is provided on the first protrusion 111. When the dovetail tenon is slidably inserted in the dovetail groove, the first abutment surface 130 and the first pressing member 11 can be limited along the length direction of the dovetail groove (i.e., the Z-axis direction), and the first abutment surface 130 and the first pressing member 11 can be limited along the depth direction of the dovetail groove (i.e., the Y-axis direction), which is conducive to preventing the first abutment member 13 from being separated from the first pressing member 11.

[0071] Continue to refer to Figure 4 , Figure 8 and Fig. 9 As shown, in this embodiment, the first abutment member 13 includes an overall thickness adjustment abutment member 1301 and a first tab thickness adjustment abutment member 1302, the first stopper member 12 includes an overall thickness adjustment stopper member 1201 and a first tab thickness adjustment stopper member 1202, the overall thickness adjustment stopper member 1201 is abutted between the first pressing member 11 and the overall thickness adjustment abutment member 1301, and the first tab thickness adjustment stopper member 1202 is disposed between the first pressing member 11 and the first tab thickness adjustment abutment member 1302. The overall thickness adjustment abutment member 1301 can directly abut a certain part of the product to be packaged (e.g., the aluminum-plastic film outside the battery tab) against the second pressing assembly 2 during packaging, thereby adjusting the packaging thickness between the first protrusion 111 and the second pressing assembly 2. The first tab thickness adjustment abutment 1302 can directly abut against another part of the product to be packaged, such as the tab of the battery, during packaging, so that the packaging thickness between the first tab thickness adjustment abutment 1302 and the second pressing assembly 2 is different from the packaging thickness between the first protrusion 111 and the second pressing assembly 2, thereby meeting the requirements for local packaging thickness at different positions of the product.

[0072] In this embodiment, the packaging head also includes an adjusting component 3, which is fixedly connected to the first pressing part 11 and transmission-connected to the first limiting part 12. The adjusting component 3 can drive the first limiting part 12 to move along the X-axis direction, thereby adjusting the distance between the first abutting surface 130 and the first pressing part 11.

[0073] like Figures 8 to 9 As shown, the adjustment assembly 3 includes a micrometer 31 and a fixed bracket 33, the fixed bracket 33 is fixedly connected to the first pressing piece 11, the housing 311 of the micrometer 31 is fixedly connected to the first pressing piece 11 by means of a clamp 32, a fastener, etc., the adjustment end 312 of the micrometer 31 is movably arranged along the X-axis direction, and the adjustment end 312 is fixedly connected to the first stopper 12. By adjusting the length of the adjustment end 312 of the micrometer 31 extending out of the housing 311, the first stopper 12 can be accurately moved along the X-axis direction. At the same time, the first stopper 12 can also reduce the pressure on the micrometer 31 during packaging, thereby reducing the wear of the micrometer 31 and ensuring its accuracy and service life.

[0074] Optionally, in the present embodiment, the first position-limiting member 12 is provided with a locking hole 125 and a connecting hole 126, which are connected to each other, the adjusting end 312 of the micrometer 31 is inserted into the connecting hole 126, and the locking screw is passed through the locking hole 125 and fixedly connected to the adjusting end 312, so as to fix the adjusting end 312 and the first position-limiting member 12. Of course, in some other embodiments, the adjusting end 312 and the first position-limiting member 12 may also be fixedly connected by means of snap connection, bonding, etc., which is not specifically limited in the present utility model.

[0075] like Fig.10 , Fig.11 As shown, the overall thickness adjustment stopper 1201 and the first tab thickness adjustment stopper 1202 are respectively connected with a micrometer 31. Among them, since the thickness of the tab is increased between the first tab thickness adjustment abutment 1302 and the second pressing assembly 2 compared with the thickness between the overall thickness adjustment abutment 1301 and the second pressing assembly 2, the extension length of the adjustment end 312 of the micrometer 31 connected to the first tab thickness adjustment stopper 1202 is shorter, and the extension length of the adjustment end 312 of the micrometer 31 connected to the overall thickness adjustment stopper 1201 is longer, so as to meet the requirements of the local packaging thickness at different positions of the product.

[0076] like Figure 2 , Figure 3 As shown, in this embodiment, the second pressing component 2 includes a second pressing member 21, a second abutting member 23 and a second stopper 22. Among them, the second pressing member 21 is provided with a second protruding portion 211, and the second protruding portion 211 can clamp the product to be packaged between the first abutting member 13 or the first protruding portion 111 during packaging, so as to package it with a preset pressure and packaging thickness. In some embodiments, the second protruding portion 211 can also have a built-in heating component, so that when the aluminum-plastic film is clamped between the second protruding portion 211 and the first pressing component 1, the aluminum-plastic film is heated according to a preset temperature to achieve heat sealing.

[0077] The second abutment 23 is similar to the first abutment 13, and is arranged at an adjustable distance from the second pressing member 21 along the Z-axis direction, and the second abutment 23 has a second abutment surface, and the second abutment surface can abut against the first protrusion 111 of the first pressing component 1 or the first abutment 13 to adjust the packaging thickness between the second pressing component 2 and the first pressing component 1. The second limiting member 22 is similar to the first limiting member 12, and is abutted between the second pressing component 21 and the second abutment 23, and the thickness dimension of the second limiting member 22 is reduced along the X-axis direction. At the same time, the second limiting member 22 is adjustable in position along the X-axis direction to the second pressing component 21 to adjust the distance between the second abutment surface and the second pressing component 21. By changing the distance between the second abutment surface and the second pressing component 21, the effect of adjusting the packaging thickness between the second pressing component 2 and the first pressing component 1 can be achieved.

[0078] Optionally, in this embodiment, the second abutment 23 includes a second tab thickness adjustment abutment 2301, the second stopper 22 includes a second tab thickness adjustment stopper 2201, and the second tab thickness adjustment stopper 2201 is abutted between the second pressing member 21 and the second tab thickness adjustment abutment 2301. The first pressing assembly 1 includes two integral thickness adjustment abutments 1301, and along the Y-axis direction, the second tab thickness adjustment abutment 2301 is located between one of the integral thickness adjustment abutments 1301 and the first tab thickness adjustment abutment 1302, so that when packaging the battery, it abuts against the first protrusion 111 located between the integral thickness adjustment abutment 1301 and the first tab thickness adjustment abutment 1302, so as to facilitate the adjustment and control of the local packaging thickness from the tab to the edge of one side of the battery.

[0079] Optionally, in this embodiment, the positive and negative tabs of the battery are located on the same side, and the first pressing assembly 1 includes two first tab thickness adjustment abutments 1302, which are used to control the packaging thickness at the positive tab and the negative tab, respectively. The second abutment 23 includes a tab middle thickness adjustment abutment 2302, and the second stopper 22 includes a tab middle thickness adjustment stopper 2202, which is abutted between the second pressing member 21 and the tab middle thickness adjustment abutment 2302. A first protrusion 111 is arranged between the two first pole ear thickness adjustment abutments 1302, and corresponding to the first protrusion 111, under the action of the pole ear middle thickness adjustment limiter 2202, the pole ear middle thickness adjustment abutment 2302 can maintain a preset distance with the second pressing member 21 along the Z-axis direction and abut the aluminum-plastic film between the positive pole ear and the negative pole ear against the first protrusion 111, thereby controlling the packaging thickness between the positive pole ear and the negative pole ear.

[0080] Optionally, in this embodiment, the second abutment 23 includes an airbag side thickness adjustment abutment 2303, and the second limiting member 22 includes an airbag side thickness adjustment limiting member, and the airbag side thickness adjustment limiting member is abutted between the second pressing member 21 and the airbag side thickness adjustment abutment 2303. Along the Y-axis direction, the airbag side thickness adjustment abutment 2303 is located between another overall thickness adjustment abutment 1301 and the first tab thickness adjustment abutment 1302, so that when packaging the battery, it abuts against the first protrusion 111 located between the overall thickness adjustment abutment 1301 and the first tab thickness adjustment abutment 1302, so as to facilitate the adjustment and control of the local packaging thickness from the tab to the edge of one side of the battery.

[0081] Preferably, in the second pressing assembly 2, one of the second pressing member 21 and the second limiting member 22 is provided with a limiting member guide groove 121, and the other is provided with a limiting member guide protrusion 112, and the limiting member guide protrusion 112 is limitedly inserted in the limiting member guide groove 121, so as to slide and connect the second pressing member 21 and the second limiting member 22 along the X-axis direction. One of the second pressing member 21 and the second abutting member 23 is provided with an abutting member guide groove 131, and the other is provided with an abutting member guide protrusion 113, and the abutting member guide protrusion 113 is limitedly inserted in the abutting member guide groove 131, so as to slide and connect the second pressing member 21 and the second abutting member 23 along the X-axis direction. The second pressing member 21 and the second limiting member 22 can be prevented from being separated by the limiting member guiding groove 121 and the limiting member guiding protrusion 112, and the second pressing member 21 and the second abutting member 23 can be prevented from being separated by the abutting member guiding groove 131 and the abutting member guiding protrusion 113. Furthermore, preferably, the limiting member guiding groove 121 and the abutting member guiding groove 131 are dovetail grooves, and the limiting member guiding protrusion 112 and the abutting member guiding protrusion 113 are dovetail tenons, so as to achieve a better limiting connection effect.

[0082] It should be noted that when the battery is bottom-side sealed, in the first pressing assembly 1, the first abutting surface 130 of the first abutting member 13 and the thermal sealing surface of the first protruding portion 111 can be adjusted to be flush in the Z-axis direction. Similarly, in the second pressing assembly 2, the second abutting surface of the second abutting member 23 and the thermal sealing surface of the first protruding portion 111 can also be adjusted to be flush in the Z-axis direction, thereby ensuring the consistency of various areas of the aluminum-plastic film during bottom-side sealing.

[0083] It is understandable that when the second pressing assembly 2 is provided with the second abutment member 23 and the second stopper 22, the packaging head also includes a second adjustment assembly 3 to adjust the position of the second stopper 22 along the X-axis direction. Similar to the first stopper 12, the second stopper 22 is provided with a locking hole 125 and a connecting hole 126, which are connected, and the adjustment end 312 of the micrometer 31 is inserted into the connecting hole 126, and the locking screw is passed through the locking hole 125 and fixedly connected to the adjustment end 312, so as to fix the adjustment end 312 and the second stopper 22.

[0084] Similar to the first limiting member 12 , the second limiting member 22 may also be provided with the first limiting portion 123 and the second limiting portion 124 to prevent the second limiting member 22 and the second abutting member 23 from being separated, which will not be repeated in the present invention.

[0085] The utility model also provides a packaging device, which includes a first driving end and a second driving end, the first driving end is equipped with a first pressing component 1 of the packaging head, and the second driving end is equipped with a second pressing component 2 of the packaging head. The first driving end and the second driving end can move toward each other along the Z-axis direction to perform packaging according to a preset packaging thickness.

[0086] Of course, in some other embodiments, the first driving end may only drive the first pressing assembly 1 to move toward the second pressing assembly 2 along the Z-axis direction, and the second driving end may keep the second pressing assembly 2 in place, or the second driving end may only drive the second pressing assembly 2 to move toward the first pressing assembly 1 along the Z-axis direction, and the first driving end may keep the first pressing assembly 1 in place. As long as the distance between the first pressing assembly 1 and the second pressing assembly 2 can be made variable along the Z-axis direction, it is within the scope of protection of the present utility model.

[0087] In the packaging device, the first stopper 12 whose thickness dimension is reduced along the X-axis direction is abutted between the first pressing member 11 and the first abutment 13, so that by moving the first stopper 12 along the X-axis direction, the distance between the first abutment 13 and the first pressing member 11 can be changed, so that the actual packaging thickness that can be achieved between the first pressing component 1 and the second pressing component 2 is changed, so that the actual packaging thickness is quickly and conveniently made the same as the preset packaging thickness, meeting the requirements of battery packaging with different thickness requirements or sealing requirements, avoiding multiple replacements of packaging heads, thereby improving production efficiency, simplifying production processes, and reducing production costs. In addition, compared with directly adjusting the distance between the first abutment 13 and the first pressing member 11 along the Z-axis direction, the distance between the first abutment 13 and the first pressing member 11 can be adjusted more accurately by moving the first stopper 12, reducing the difficulty of adjusting the packaging accuracy, and also helping to improve packaging quality and product quality.

[0088] In this embodiment, the first pressing component 1 is arranged below the second pressing component 2, and in some other embodiments, the second pressing component 2 can also be arranged below the first pressing component 1, or the second pressing component 2 can be arranged on one side of the first pressing component 1, so that the two can move toward each other in the horizontal direction or in other directions at an angle to the horizontal direction to encapsulate the product, and this is not specifically limited in the present invention.

[0089] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
