Description

Technical Field

[0001] The utility model relates to the technical field of button battery processing, in particular to a button battery encapsulation device. Background Art

[0002] A button soft-pack battery refers to a type of battery with a button-like shape and an aluminum-plastic film wrapping the battery core. With the development of smart wearable device technology, the market demand for button soft-pack batteries is increasing day by day.

[0003] One of the processing procedures of button batteries is encapsulation processing. As shown in Figure 4 After the ear of the button battery 21 is bent reversely to fit on the outer side wall of the button battery 21, the tape 30 is wound around the outer side wall of the button battery 21 to fix the button battery 21 and the ear together with the tape. In this way, when the ear 22 is pulled by an external force, the aluminum-plastic film shell of the ear 22 and the button battery 20 will not be directly stressed, so the structural strength between the ear 22 and the button battery 21 can be effectively guaranteed. Among them, the tape 30 needs to be wound around the outer side wall of the button battery 21 for at least two turns.

[0004] At present, it mainly relies on workers to hold the button battery and then wind the tape 30. However, this method has the following disadvantages: First, the manual winding method is inefficient, and the winding quality varies greatly among different workers; second, as smart wearable devices become smaller and smaller, the volume of button batteries is also getting smaller and smaller, and it becomes more and more difficult to manually hold the button battery to wind the tape 30; finally, since the sizes of button batteries required by different manufacturers are also inconsistent, when changing production, workers often need a long time to adapt to the new battery volume, which is likely to affect the production cycle. Therefore, in order to solve the above deficiencies and effectively improve the encapsulation efficiency and quality of button batteries, the button battery encapsulation device of this application is proposed.

[0029] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings.

[0030] As Figure 1 shown, a button battery encapsulation device 10 includes a base 100, a material loading assembly 200 and a rotating assembly 300. The material loading assembly 200 includes a lower rotating seat 210 and a top seat 220. The lower rotating seat 210 is rotatably arranged on the base 100, and the top seat 220 is detachably arranged on the lower rotating seat 210. An adsorption hole 221 is formed in the top seat 220. The rotating assembly 300 includes a lifting driving member 310, a lifting plate 320, a rotating driving member 330, a rotating shaft 340 and a pressing seat 350. The lifting plate 320 is slidably arranged on the base 100 along the vertical direction. The lifting driving member 310 is arranged on the base 100, and the output shaft of the lifting driving member 310 is connected to the lifting plate 320. The rotating driving member 330 is arranged on the lifting plate 320. The rotating shaft 340 is slidably arranged on the base 100, and the rotating shaft 340 is connected to the output shaft of the rotating driving member 330. The pressing seat 350 is detachably arranged at one end of the rotating shaft 340 away from the rotating driving member 330, and the pressing seat 350 is located above the top seat 220. When the lifting driving member 310 is used to drive the lifting plate 320 to descend, the pressing seat 350 and the top seat 220 jointly clamp the button battery. When the rotating driving member 330 is used to drive the rotating shaft 340 to rotate, the pressing seat 350 and the top seat 220 drive the button battery to rotate.

[0031] It should be noted that the lower turntable 210 is mounted on the base 100 through bearings, enabling the lower turntable 210 to rotate relative to the base 100. The top seat 220 is detachably mounted on the lower turntable 210. The top seat 220 is used to support the button cell. Since the sizes of button cells are inconsistent, the top seat 220 is configured to be detachably mounted relative to the lower turntable 210, and can be replaced with a correspondingly adapted top seat 220 according to the specific diameter of the button cell. Further, adsorption holes 221 are formed in the top seat 220. The adsorption holes 221 are used to communicate with an external vacuum generator. In this way, negative pressure is formed in the adsorption holes 221, causing the button cell to be adsorbed and fixed on the end face of the top seat 220. The lifting plate 320 is mounted on the base 100 through a slide rail. For example, the base 100 includes a vertical plate 110 and a horizontal plate 120. The horizontal plate 120 is disposed on the vertical plate 110. The lifting plate 320 is mounted on the vertical plate 110 through a slide rail, enabling the lifting plate 320 to perform a lifting motion relative to the vertical plate 110. The lifting driving member 310 is mounted on the vertical plate 110, and the output shaft of the lifting driving member 310 is connected to the lifting plate 320. In this way, the lifting driving member 310 is utilized to drive the lifting plate 320 to perform a lifting motion. In one embodiment, the lifting driving member 310 is a linear power source such as a cylinder. The rotary driving member 330 is mounted on the lifting plate 320. One end of the rotating shaft 340 is connected to the output shaft of the rotary driving member 330, and the other end of the rotating shaft 340 passes through the horizontal plate 120. The pressing seat 350 is fixedly mounted on the bottom end of the rotating shaft 340, and the pressing seat 350 is aligned with the top seat 220. In this way, when the lifting driving member 310 drives the lifting plate 320 to descend so that the pressing seat 350 and the top seat 220 jointly clamp the button cell, the rotary driving member 330 drives the rotating shaft 340 to rotate, so that the pressing seat 350, the top seat 220 and the button cell rotate synchronously. In this way, the worker only needs to bond one end of the tape to the outer sidewall of the button cell before the button cell rotates. As the button cell rotates, the tape can wind around the button cell for one week to complete encapsulation. It should be noted that since both the top seat 220 and the pressing seat 350 are of a detachable and replaceable structure, and the clamping distance between the top seat 220 and the pressing seat 350 is also adjustable, structures adapted to different sizes of button cells can be replaced. In this way, compared with the existing operation of relying on workers to hold the button cell for encapsulation, the present application is more suitable for encapsulation processing of small batches of button cells with different sizes, and can effectively improve the encapsulation efficiency and encapsulation quality.

[0032] As Figure 2 and Figure 3As shown, in one embodiment, the lower turntable 210 includes a turntable body 211 and a positioning post 212. The turntable body 211 is rotatably arranged on the base 100. The axis of the positioning post 212 coincides with the rotation center of the turntable body 211. An air hole 2121 is formed in the axis of the positioning post 212. A positioning groove 222 communicating with the adsorption hole 221 is formed in the top seat 220. The positioning post 212 is adaptively inserted into the positioning groove 222 so that the adsorption hole 221 communicates with the air hole 2121.

[0033] It should be noted that the turntable body 211 is installed on the base 100 by using a bearing. The positioning post 212 is located at the rotation center position of the turntable body 211. An air hole 2121 is formed in the positioning post 212, and a positioning groove 222 is formed in the top seat 220, where the positioning post 212 and the positioning groove 222 are adapted to each other. In this way, when the top seat 220 is sleeved on the turntable body 211, the positioning post 212 is adaptively inserted into the positioning groove 222, so that the center of the top seat 220 is aligned with the center of the positioning post 212. The adsorption hole 221 communicates with the air hole 2121. In this way, when the button battery is placed on the top end face of the top seat 220, the button battery is adsorbed and fixed on the top seat 220, and the button battery can rotate following the top seat 220.

[0034] In one embodiment, the positioning post 212 is a frustum of a cone or a frustum of a pyramid. In this way, when the top seat 220 is sleeved on the positioning post 212, the top seat 220 and the positioning post 212 are coaxially arranged. In this way, the top seat 220 can be quickly disassembled and assembled. Among them, the top seat 220 and the turntable body 211 are locked and fixed by fasteners such as screws.

[0035] As Figure 2 and Figure 3 shown, in one embodiment, a sealing ring 230 is arranged on the surface of the turntable body 211, and the sealing ring 230 abuts against the bottom surface of the top seat 220.

[0036] In this way, when replacing different top seats 220, the sealing ring 230 can be used to eliminate the gap between the top seat 220 and the turntable body 211.

[0037] As Figure 1 shown, in one embodiment, the rotating shaft 340 includes a shaft body 341 and an upper turntable 342. The shaft body 341 is slidably arranged on the base 100. One end of the shaft body 341 is connected to the output shaft of the rotation driving member 330. The upper turntable 342 is coaxially arranged at the other end of the shaft body 341, and the upper turntable 342 is aligned with the lower turntable 210. The pressing seat 350 is detachably arranged on the lower side surface of the upper turntable 342.

[0038] It should be noted that the shaft body 341 is slidably mounted on the base 100. For example, a linear bearing is mounted on the cross plate 120 of the base 100, and the shaft body 341 is adaptively passed through the linear bearing, so that the shaft body 341 can rotate relative to the cross plate 120 and can also slide through the cross plate 120. In this way, when the rotary driving member 330 drives the shaft body 341 to rotate relative to the cross plate 120, when the lifting driving member 310 drives the lifting plate 320 to perform a lifting motion, the shaft body 341 drives the upper rotating seat 342 to perform a lifting motion relative to the cross plate 120.

[0039] In one embodiment, the structure of the upper rotating seat 342 is the same as that of the lower rotating seat 210. In this way, the structure of the upper rotating seat 342 is set to be the same as that of the lower rotating seat 210. Correspondingly, the structure of the pressing seat 350 is set to be the same as that of the top seat 220. In this way, it is convenient to quickly assemble the pressing seat 350 on the upper rotating seat 342. In this way, for button batteries that need to frequently change production, have small batches, and small sizes, using the button battery encapsulation device 10 of the present application to assist in wrapping the tape around the button battery can quickly complete the assembly of the top seat 220 and the pressing seat 350 for encapsulating the button battery.

[0040] As Figure 1 shown, in one embodiment, the rotating assembly 300 further includes a top column 360 and a holding nut 370. The top column 360 is screwed onto the cross plate 120, the holding nut 370 is screwed onto the top column 360, and the holding nut 370 is screwed onto the top column 360. The top column 360 is used to abut against the lifting plate 320.

[0041] It should be noted that button batteries of different sizes often have different heights. In order to reliably clamp the button battery between the pressing seat 350 and the top seat 220, a top column 360 is screwed onto the cross plate 120, and the top of the top column 360 is used to hold the lifting plate 320. In this way, by rotating the top column 360 to adjust the distance between the top column 360 and the lifting plate 320, and then rotating the holding nut 370 to abut against the cross plate 120, the top column 360 is reliably fixed to the cross plate 120. In this way, it means that when the lifting plate 320 descends to abut against the top column 360, it descends to the lowest position. In this way, by adjusting the top column 360, the distance for clamping the button battery between the pressing seat 350 and the top seat 220 can be adjusted.

[0042] As Figure 1 shown, in one embodiment, the rotating assembly 300 further includes a displacement sensor 380 and a pressure regulating column 390. The pressure regulating column 390 is screwed onto the cross plate 120, the displacement sensor 380 is arranged on the lifting plate 320, and the displacement sensor 380 is aligned with the pressure regulating column 390.

[0043] It should be noted that, in order to precisely adjust the distance between the pressure seat 350 and the top seat 220, ensure that the button cell is reliably clamped without being damaged, a pressure regulating column 390 is installed on the cross plate 120, and a displacement sensor 380 is installed by screwing on the lifting plate 320. In this way, when a new pressure seat 350 and top seat 220 are replaced, first, the lifting driving member 310 drives the lifting plate 320 to descend, so that the pressure seat 350 and the top seat 220 are in contact with each other. Then, by rotating the pressure regulating column 390 to rise, after the pressure regulating column 390 pushes against the detection end of the displacement sensor 380, the pressure regulating column 390 is locked and fixed on the cross plate 120 by a nut, and the displacement sensor 380 is zeroed. Then, by adjusting the distance of the top column 360 relative to the cross plate 120, the top column 360 pushes the lifting plate 320 to rise. At this time, the pressure seat 350 will be lifted away from the top seat 220. At the same time, the displacement sensor 380 will display the rising distance. In this way, through the reading of the displacement sensor 380, the distance between the pressure seat 350 and the top seat 220 can be precisely adjusted, so that the button cell can be reliably clamped and fixed.

[0044] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. Among them, the installation / fixing / setting mentioned in the present utility model can be understood as including but not limited to locking and fixing by using screws / screws, welding unless otherwise specifically defined. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
