Description

Technical Field

[0001] This invention relates to a winding device. Background Technology

[0002] With the widespread use of electronic devices, the demand for batteries in electronic products such as tablets, computers, and mobile phones has also exploded.

[0003] At this point, a multi-parameter label indicating traceable information such as the battery pack's name, model, manufacturing date, and manufacturer needs to be affixed to the battery pack's casing. Furthermore, for aesthetic and durability reasons, there is a need to wrap protective labels around the battery casing.

[0004] However, when manually attaching battery labels, not only is the attaching efficiency low, but the failure rate is also high, and air bubbles appear on the two curved surfaces after attaching.

[0005] In response to this, existing technologies have proposed using cylinders to drive rollers for attaching battery tags. For example, Patent Document 1 proposes an automatic attaching device comprising an attaching assembly one and an attaching assembly two, both detachably mounted on an attaching machine. The attaching assembly one includes a roller assembly one and a cylinder assembly one for driving the roller assembly one to rotate. The cylinder assembly one includes a cylinder one for pushing the roller assembly one to rotate vertically and a cylinder two for pushing the roller assembly one to rotate horizontally. The attaching assembly two includes a roller assembly two and a cylinder assembly two for driving the roller assembly two to rotate. The cylinder assembly two includes a cylinder three for driving the roller assembly two to rotate vertically and a cylinder four for driving the roller assembly two to rotate horizontally.

[0006] However, in this patent document 1, multiple cylinders are required to drive the roller assembly to roll, and the roller assembly can only be driven to move in the vertical or horizontal direction. Therefore, the winding operation is complicated and cannot be adapted to various battery shapes such as cylindrical batteries, resulting in low winding efficiency.

[0015] Furthermore, preferably, in the winding device, the limiting track groove is provided on the limiting plate, the limiting plate can be attached and detached relative to the winding device, and through this attachment and detachment, the limiting track groove with different track paths can be replaced.

[0016] Furthermore, preferably, in the winding device, the combination of the second displacement mechanism, the roller, and the limiting track groove is arranged in pairs on both sides of the second direction.

[0021] Hereinafter, embodiments of the present invention will be described using the accompanying drawings. However, various limitations, technically preferred for carrying out the present invention, are added to the embodiments described below. Therefore, the scope of the technology disclosed herein is not limited to the following embodiments and the illustrated examples. Furthermore, the sizes, shapes, and proportions in the illustrated examples are merely illustrative and do not represent specific sizes, shapes, and proportions. In addition, in the drawings, common components in the embodiments are labeled with the same symbols, and repeated symbols and descriptions are omitted for symmetrical components.

[0022] Figure 1 An exploded view illustrating an embodiment of the winding apparatus 100 of the present invention. Figure 2 This is a perspective view schematically showing the assembled winding device 100 according to one embodiment of the present invention. Figure 3 This is a front view schematically illustrating a winding apparatus 100 according to one embodiment of the present invention. In the following description, for the winding apparatus 100, the vertical direction is taken as an example of a first direction, the left-right direction orthogonal to the first direction is taken as an example of a second direction, and the depth direction orthogonal to both the first and second directions is taken as an example of a third direction.

[0023] like Figure 1 As shown, the winding device 100 includes a cylinder 110, a slider 120, a slide rail 130, a slider 140, a roller 150, a limiting plate 160, a base plate 170, side plates 180, and a top plate 190. The base plate 170, which is placed on the table, the two side plates 180 on the left and right sides, and the top plate 190 connecting the two side plates 180 are assembled to form the support of the winding device 100.

[0024] Cylinder 110 is fixed to top plate 190. Cylinder 110 contains cylinder barrel 111, and cylinder barrel 111 contains a piston (not shown) capable of moving vertically. Air pressure drives the piston within cylinder barrel 111 to move up and down. Cylinder 110 can be a double-acting cylinder that uses air pressure to reciprocate the piston's vertical movement, or it can be a single-acting cylinder that uses air pressure to move the piston downwards and resets it using elastic force. Furthermore, in addition to air pressure, electromagnetic cylinders driven by electromagnetic force can also be considered.

[0025] Below cylinder 110, slider 120 is connected to the piston of cylinder 110. Slider 120 is an example of a first displacement mechanism. By using air pressure to push the piston of cylinder 110 up and down, slider 120, coupled to the piston, can move in the vertical direction. Alternatively, slider 120 and piston of cylinder 110 are fixedly connected to each other by a connecting rod, but it is also possible for the piston itself to serve as a rodless structure for slider 120.

[0026] Furthermore, the illustration shows an example where the slider 120 connected to the cylinder 110 serves as the first displacement mechanism, but other structures are also possible as long as the first displacement mechanism can reciprocate up and down. For example, instead of the cylinder, a guide rail along the vertical direction can be provided, and the slider mounted on the guide rail can serve as the first displacement mechanism. In this case, the slider can be driven up and down by, for example, a handle.

[0027] A slide rail 130 is mounted on the bottom surface below the slider 120. The slide rail 130 is arranged along the left-right direction of the winding device 100, and a pair of sliders 140 are provided on the slide rail 130. That is, the sliders 140 are located on the bottom surface below the slider 120 and can move freely in the left-right direction via the slide rail 130. The slider 140 is an example of a second displacement mechanism. The slider 140 is a driven mechanism. When the slider 120 is driven by the cylinder 110, the slider 140 moves left and right on the slide rail 130 due to the abutting force from the limiting track groove 161 (described later) and the object to be wound 200. That is, through the slider 120 as the first displacement mechanism and the slider 140 as the second displacement mechanism, the roller 150 (described later) can move in a plane orthogonal to the depth direction of the winding device 100.

[0028] Below each of the pair of sliders 140, a pair of arms 141 are integrally provided with the slider 140, and the pair of arms 141 are opposite each other in the depth direction of the winding device 100. The roller 150 is inserted through a shaft 151, and by locking the shaft 151 to the pair of arms 141 of the slider 140 in the depth direction of the winding device 100, the roller 150 is fixed to the slider 140 and can rotate freely about the shaft 151.

[0029] Roller 150 is a mechanism for winding the object 200. It is cylindrical and its diameter and length are matched to the shape and size of the object 200. For example, the shaft 151 can be attached to or detached relative to the arm 141 of the slider 140, and rollers 150 of different sizes can be replaced, thereby facilitating the winding of different objects 200.

[0030] On both sides of the winding device 100 in the depth direction, limit plates 160 are respectively installed, and slots are cut into each limit plate 160, which are called limit track slots 161. In the figure, a pair of limit track slots 161 are shown to match a pair of left and right sliders 140. The limit plates 160 are installed, for example, between a pair of side plates 180 and can be freely installed and removed relative to the side plates 180. Alternatively, the limit plates 160 may be provided only on one side in the depth direction.

[0031] Each arm 141 of the slider 140 is provided with a limiting member 142, which is locked in the limiting track groove 161 of the limiting plate 160. For example, the limiting member 142 is a roller, which is locked in the limiting track groove 161 by a snap-fit ​​and can move along the track path of the limiting track groove 161. Alternatively, the limiting member 142 can also be a bolt, which passes through the limiting track groove 161 of the limiting plate 160 and is fixed to the slider 140, and can move along the track path of the limiting track groove 161.

[0032] The limiting track groove 161 has a track path that matches the position, size and shape of the object to be rolled 200. The displacement path of the roller 150 is restricted by the displacement of the limiting member 142 along the track path of the limiting track groove 161, so as to implement the rolling matching the object to be rolled 200.

[0033] Furthermore, the displacement path of the roller 150 is restricted so that the roller 150 always maintains a predetermined preload on the winding surface of the workpiece 200. Considering the size of the workpiece being wound as a battery, this predetermined preload is preferably 1 mm. By maintaining a predetermined preload on the winding surface of the workpiece 200 by the roller 150, the generation of air bubbles can be effectively prevented.

[0034] Furthermore, by attaching and detaching the limiting plate 160 relative to the winding device 100 (side plate 180), the limiting plate 160 with a different track path 161 can be replaced, thereby enabling winding for different objects 200 to be wound.

[0035] In the base plate 170 of the winding device 100, a groove is provided for accommodating the item to be wound 200 or a fixture carrying the item to be wound 200, thereby fixing the position of the item to be wound 200. The item to be wound 200 is, for example, a battery, and a label 210 is to be wound. With the winding device 100 of the embodiment, winding for different types of batteries can be realized. For example, by changing the track path of the limiting track groove 161, winding for cylindrical batteries or rectangular batteries with rounded corners can be realized. In addition, the item to be wound 200 can also be other daily necessities, electronic products, etc., and the item to be wound can be other objects that can be attached, such as protective films, in addition to labels.

[0036] The illustration shows the limiting track groove 161 having a track path that combines a short vertical path and a quarter-circular path. The short vertical path reduces initial sliding resistance, allowing the piston force from the cylinder 110 to reliably move the roller 150 and apply the aforementioned preload to the winding surface of the object to be wound 200. The quarter-circular path, for example, is a track path adapted to a cylindrical battery, enabling the roller 150 to wind the label 210 of the object to be wound 200 (which is a cylindrical battery) while maintaining the aforementioned preload during winding.

[0037] For the winding process performed by the winding device 100 of the embodiment, initially, the roller 150 and the limiting member 142 are locked on the slide rail 130, and the limiting member 142 is fixed on the limiting track groove 161. With each up-and-down reciprocation of the cylinder 110, the limiting member 142 moves along the limiting track groove 161, completing the winding of one object 200, and returning to the initial position. Thus, the winding device 100 of the embodiment achieves winding with high flatness, good quality, and less likelihood of generating air bubbles.

[0038] Furthermore, the illustration shows a configuration where the winding device 100 is arranged in pairs along its left-right direction, consisting of sliders 140, rollers 150, and limiting track grooves 161. This allows multiple rollers to be driven by a single cylinder, enabling the winding of various shapes and sizes of objects 200 to be wound in one operation. However, depending on the actual winding requirements, the combination of sliders 140, rollers 150, and limiting track grooves 161 can also be provided only on one side in the left-right direction.

[0039] The embodiments of the present invention have been described above with reference to the accompanying drawings. These embodiments are merely specific examples of the present invention, used to understand the invention, and are not intended to limit the scope of the invention. Those skilled in the art can make various modifications, combinations, and reasonable omissions of elements in the embodiments based on the technical concept of the present invention, and the resulting methods are also included within the scope of the present invention.
