Description

Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to film material positioning equipment and methods. Background Technology

[0002] During battery encapsulation, the aluminum-plastic film (also known as aluminum film, a smooth, opaque film with other materials encased in aluminum foil) needs to be perforated. This perforation process typically involves first using vacuum adsorption to fix the film onto a lower mold, then using an upper mold to stamp it, creating grooves in the otherwise flat film. However, using existing vacuum adsorption methods for film positioning can easily lead to displacement or floating, resulting in weak adhesion between the film and the lower mold.

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the embodiments of this application.

Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0062] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0063] This application discloses a film material positioning device and method.

[0064] Please see Figure 1 One embodiment of the film material positioning device and method provided in this application includes:

[0065] Feeding device 200, positioning device 100 and mold 300.

[0066] The mold 300 is equipped with a film material positioning area.

[0067] The feeding device 200 is used to support the unfolded film material 400 between the positioning device 100 and the mold 300. The feeding device 200 is provided with a feeding adsorption component for adsorbing or releasing the film material 400.

[0068] The positioning device 100 is used to press the film material on the feeding device 200 onto the film material positioning area of ​​the mold 300. The positioning device 100 is provided with a positioning adsorption component for adsorbing or releasing the film material 400.

[0069] The extrusion method can effectively press and fix the film material 400 onto the mold 300. Moreover, the positioning device 100 is designed with a positioning adsorption component for adsorbing or releasing the film material 400. By cooperating with the feeding adsorption component, when the positioning device 100 contacts the film material 400, the feeding adsorption component releases the film material 400 while the positioning component adsorbs it. This can prevent the film material 400 from being damaged or wrinkled due to pulling. Furthermore, the adsorption and fixing effect of the positioning adsorption component during the pressing process can more smoothly press the film material 400 onto the mold 300 and solve the problems of displacement and floating.

[0070] The above is Embodiment 1 of the film material positioning device and method provided in this application. The following is Embodiment 2 of the film material positioning device and method provided in this application. Please refer to the following for details. Figures 1 to 5 .

[0071] Based on the solution of Embodiment 1 above:

[0072] Furthermore, the film material positioning area has a first convex arc surface 31 and a first concave arc surface 41.

[0073] The first convex arc surface 31 and the first concave arc surface 41 are arranged at intervals along their own arc edges.

[0074] The positioning device 100 is provided with a second convex arc surface 11 and a second concave arc surface 12; the second convex arc surface 11 can fit with the first concave arc surface 41, and the second concave arc surface 12 can fit with the first convex arc surface 31. The arc surfaces are designed with alternating concave and convex shapes, so that after subsequent punching, the film material 400 can be folded so that the portion of film material 400 located on the first convex arc surface 31 can match the portion of film material 400 located on the first concave arc surface 41. Correspondingly, in this application, the curvature of the first concave arc surface 41 and the first convex arc surface 31 are consistent to ensure that they can fit together after subsequent folding.

[0075] Furthermore, the positioning device 100 includes a pressure plate 1, a first lifting mechanism 2, and a first control component (not shown in the figure).

[0076] The second convex arc surface 11 and the second concave arc surface 12 are provided on the pressure plate 1.

[0077] The second concave arc surface 12 and the second convex arc surface 11 are provided with a plurality of first adsorption holes (not shown in the figure); the first control component is connected to the first adsorption holes to form a positioning adsorption component; the first control component is a common solenoid valve component, used to control the adsorption or release of the membrane material 400 by the first adsorption holes.

[0078] The first lifting mechanism 2 is connected to the pressure plate 1 and is used to move the pressure plate 1 closer to or away from the mold 300. Specifically, the first lifting mechanism 2 uses extrusion to press the film material 400 onto the first convex arc surface 31 and the first concave arc surface 41 of the mold 300. By extruding the air between the film material 400 and the first convex arc surface 31 and the first concave arc surface 41, the film material 400 can be firmly adhered to the mold 300 to achieve positioning. The pressure plate 1 has a vacuum plate structure with an internal air cavity, allowing the first control group to control the ventilation of the first adsorption hole through the air cavity. The structure of the pressure plate 1 can be modified according to actual needs and is not limited.

[0079] Furthermore, the feeding device 200 includes a feeding mechanism 5 and a second control component (not shown in the figure).

[0080] The feeding mechanism 5 is used to support the unfolded film material 400 between the positioning device 100 and the mold 300. The feeding mechanism 5 is provided with a number of second adsorption holes 202.

[0081] The second control component is connected to the second adsorption hole 202 to form a feeding adsorption component. The second control component is used to control the adsorption or release of the membrane material 400 by the second adsorption hole 202.

[0082] The feeding mechanism 5 is provided with an avoidance area that cooperates with the mold 300 and the avoidance positioning device 100.

[0083] Furthermore, the feeding mechanism 5 includes a feeding base 51 and a support 52.

[0084] Two support members 52 are installed alternately on the feeding base 51, forming a clearance area between them. Each support member 52 is provided with a second adsorption hole 202. The feeding base 51 can be a plate-shaped structure, while the support member 52 can be a strip-shaped structure; the specific design can be customized according to actual needs without limitation. Each support member 52 also has an internal air chamber to facilitate the second control component in controlling the ventilation of the second adsorption hole 202; this is also not limited.

[0085] Furthermore, both support members 52 are slidably mounted on the feeding base 51 with adjustable displacement, so that the distance between the two support members 52 is adjustable. This design can accommodate the fixing of various sizes of film material 400, further improving applicability.

[0086] Furthermore, regarding the adjustable and movable design, the feeding base 51 is provided with a guide rail 511, and the support member 52 is provided with a guide groove 521 that slides with the guide rail 511, thereby realizing the sliding connection between the support member 52 and the feeding assembly.

[0087] The support member 52 has a countersunk hole 522 that penetrates itself. The guide rail 511 has multiple threaded holes 512 spaced along its length that can correspond to and mate with the countersunk hole 522. A fastener is movably inserted into the countersunk hole 522 and threadedly engaged with the threaded hole 512 to securely connect the support member 52 to the guide rail 511. This fastener can be a screw or bolt, which passes through the countersunk hole 522 and mates with the threaded hole 512 to fasten the support member 52 to the guide rail 511. When adjustment of displacement is required, the fastener is loosened, the support member 52 is slid to the designated position, and then the fastener is tightened again, making operation convenient. In addition, the countersunk hole 522 can be an oval-shaped countersunk hole 522, which can increase the displacement adjustment range to meet the needs of fine adjustment and make the adjustment accuracy more accurate. Those skilled in the art can make appropriate design variations based on this, without limitation.

[0088] Furthermore, a scale 513 is provided on one side of the guide rail 511 on the feeding base 51, or scale lines are directly drawn, so that displacement adjustment can be made more accurately and the use is more convenient.

[0089] Furthermore, the feeding device 200 also includes a second lifting mechanism 6.

[0090] The second lifting mechanism 6 is connected to the feeding mechanism 5 and is used to drive the feeding mechanism 5 to move along the cooperation direction between the positioning device 100 and the mold 300. Taking the pressure plate 1 of the positioning device 100 and the mold 300 as being vertically aligned, the second lifting mechanism 6 also drives the feeding mechanism 5 to move vertically. By setting the second lifting mechanism 6, the position of the film material 400 can be adjusted, making it more convenient to use.

[0091] Furthermore, it also includes a third lifting mechanism 7.

[0092] The third lifting mechanism 7 is connected to the mold 300 and is used to drive the mold 300 to move along the direction of the positioning device 100 and the mold 300, that is, to drive the mold 300 to move closer to or away from the pressure plate 1. By setting the third lifting mechanism 7, the mold 300 can also have a lifting control function, so that it can be used in conjunction with the first lifting mechanism 2 to improve the efficiency of the cooperation between the mold 300 and the pressure plate 1.

[0093] In this application, the first lifting mechanism 2, the second lifting mechanism 6, and the third lifting mechanism 7 can all be lifting cylinder mechanisms. For specific design, please refer to existing lifting cylinder devices, which will not be elaborated here.

[0094] Furthermore, the mold 300 is designed to include two independent first mold body 3 and second mold body 4.

[0095] The first mold body 3 and the second mold body 4 are parallel and spaced apart. The first convex arc surface 31 is provided on the first mold body 3, and the first concave arc surface 41 is provided on the second mold body 4. There are two third lifting mechanisms 7, which are connected to the first mold body 3 and the second mold body 4 respectively. With this design, the first convex arc surface 31 and the first concave arc surface 41 can be controlled separately, so as to control the contact sequence between each arc surface and the film material 400. Compared with the method of lifting together to achieve bonding, the film material 400 can be bonded to the first convex arc surface 31 and the first concave arc surface 41 without creases, and the bonding effect is better.

[0096] In use, the first lifting mechanism 2 moves the pressure plate 1 closer to the mold 300. Taking the vertical alignment of the pressure plate 1 and the mold 300 as an example, this means the pressure plate 1 moves downward. When the second convex arc surface 11 of the pressure plate 1 contacts the film material 400 on the feeding mechanism 5, the first control component controls the first suction hole to absorb the film material 400. At the same time, the second control component controls the second suction hole 202 to release the film material 400, thus achieving the fixed transfer of the film material 400. Afterward, the third lifting mechanism 7 connected to the second mold body 4 moves the second mold body 4 upward, so that the first concave arc surface 41 on the second mold 300 fits against the second convex arc surface 11 on the pressure plate 1. Then, the third lifting mechanism 7 connected to the first mold body 3 moves the first mold body 3 upward, so that the first convex arc surface 31 of the first mold body 3 fits against the second concave arc surface 12 on the pressure plate 1. Afterward, the first control component controls the first suction hole to release the film material 400, so that the film material 400 is fixed on the mold 300. The positioning operation performed in this sequence allows the film 400 to adhere to the first convex arc surface 31 and the first concave arc surface 41 without creases, resulting in a better adhesion effect.

[0097] Furthermore, to achieve automatic linkage between the first and second control components, the first control component is designed to send a signal to the second control component when it detects that the pressure plate 1 has adsorbed the film material 400 located on the feeding mechanism 5. This causes the second control component to respond to the signal by controlling the feeding mechanism 5 to release the film material 400, thereby achieving automatic linkage control. Additionally, the first control component is also used to issue an alarm signal when it detects an abnormality in the adsorption of the film material 400 by the pressure plate 1. Abnormal situations include, but are not limited to, prolonged non-adsorption due to insufficient material, and abnormal falling of the film material 400 after adsorption.

[0098] Of course, other detection devices (not shown in the figure) can also be added for detection. The detection device is electrically connected to the first control component and the second control component, and is used to detect whether the second convex surface 11 contacts the film material 400 on the feeding mechanism 5. The first control component is used to control the pressure plate 1 to adsorb the film material 400 when the detection device detects that the second convex surface 11 contacts the film material 400 on the feeding mechanism 5. The second control component is used to control the feeding mechanism 5 to release the film material 400 when the detection device detects that the second convex surface 11 contacts the film material 400 on the feeding mechanism 5. The detection device can be an infrared, laser or other ranging device, which is set on the side of the pressure plate 1 and is used to detect the distance between the pressure plate 1 and the film material 400 on the feeding mechanism 5. Since the distance of the second convex surface 11 relative to the ranging device is known, the distance fed back by the ranging device will change continuously when the pressure plate 1 moves down. When the distance reached is equal to the relative distance between the ranging device and the second convex surface 11, it can be regarded as the second convex surface 11 contacting the film material 400. Those skilled in the art can make appropriate design variations based on this, without any restrictions.

[0099] like Figure 6 As shown, this application also discloses a film material positioning method, applied to the film material positioning equipment of Embodiment 1 or Embodiment 2 above, comprising:

[0100] S1, when the positioning device comes into contact with the film material on the feeding device, the feeding adsorption component is controlled to release the film material, and the positioning adsorption component is controlled to adsorb the film material.

[0101] S2, the control positioning device presses the adsorbed film material onto the positioning area of ​​the mold.

[0102] The above method can be controlled by a control device. Specifically, before step S1, in response to background instructions or operation instructions issued by the user through the device operation interface, the first lifting mechanism 2 is controlled to move the pressure plate 1 toward the mold 300 until the second convex arc surface 11 on the pressure plate 1 contacts the film material 400 on the feeding mechanism 5.

[0103] Specifically, step S1 involves obtaining the distance between the second convex arc surface 11 and the film material 400 located on the feeding mechanism 5. When the distance is zero, it is determined that the pressure plate 1 is in contact with the film material 400 on the feeding mechanism 5. At this time, the pressure plate 1 is controlled by the first control component to adsorb the film material 400, and the feeding mechanism 5 is controlled by the second control component to release the film material 400.

[0104] In step S2, specifically, the first lifting mechanism 2 is controlled to move the compression closer to the mold 300 until the film material 400 adsorbed on the pressure plate 1 is pressed and fixed onto the first convex arc surface 31 and the second concave arc surface 12 of the mold 300. It should be noted that when the mold 300 is the one in the above embodiment 2, which includes a first mold body 3 and a second mold body 4, the third lifting mechanism 7 connected to the second mold body 4 is controlled to move the second mold body 4 upward so that the first concave arc surface 41 on the second mold 300 fits against the second convex arc surface 11 on the pressure plate 1. Then, the third lifting mechanism 7 connected to the first mold body 3 is controlled to move the first mold body 3 upward so that the first convex arc surface 31 of the first mold body 3 fits against the second concave arc surface 12 on the pressure plate 1. Then, the first control component is controlled to release the film material 400 from the first adsorption hole so that the film material 400 is fixed onto the mold 300.

[0105] The above provides a detailed description of the film material positioning equipment and method provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
