Technical Field

[0001] This application relates to the field of material collection technology, and more particularly to a collection device. Background Technology

[0002] Taking the tabs of lithium batteries as an example, during the process of cutting tabs on the roll substrate, the cut waste material will automatically fall off. Existing equipment cannot effectively collect the waste material, which increases the difficulty of waste recycling, resulting in a low utilization rate of the roll substrate and also increases the cost of lithium batteries. Utility Model Content

[0003] This application relates to a collection device capable of collecting processed materials or waste.

[0004] This application provides a collection device, including a suction plate and a first driving member. The suction plate includes a first surface and a second surface that are disposed opposite to each other along its own thickness direction. Both the first surface and the second surface are capable of adsorbing a target object. The first driving member is driven to the suction plate and is capable of driving the suction plate to rotate so that the first surface or the second surface faces the target object.

[0005] In this application, when the target object is electrode waste from the electrode cutting process, the electrode waste is adsorbed by a suction plate and then transported to the next process or stored in a collection module to facilitate the secondary use of the electrode waste, thereby improving the material utilization rate. Taking the electrode cutting of lithium batteries as an example, this improves the utilization rate of the electrode substrate and helps to reduce the overall cost of the electrode and lithium battery.

[0006] After the first surface of the suction plate adsorbs the target object, the first driving component can drive the suction plate to rotate, so that the second surface of the suction plate faces the target object. At this time, the first surface can release the adsorption of the target object, so that the target object falls into the next process or collection module. At the same time, the second surface can adsorb the next target object, thereby improving the adsorption efficiency of the suction plate on the target object.

Alternatively, the second driving component includes at least a first cylinder and a second cylinder.

The second cylinder is driven to the fourth fixing plate, and the second fixing plate is mounted on the fourth fixing plate. The first cylinder and the second cylinder can drive the third fixing plate and the fourth fixing plate to move synchronously in the thickness direction of the suction plate, so as to drive the first fixing plate, the second fixing plate, and the first driving component to move synchronously.

[0011] In one possible design, the collecting device further includes a collecting module located on the side of the suction plate away from the target object along the thickness direction of the suction plate; the collecting module is capable of moving toward or away from the suction plate along a second direction, the second direction being perpendicular to the thickness direction of the suction plate, and the second direction being parallel to or having an angle greater than zero with the first direction.

[0012] In one possible design, the collection device further includes a fifth fixing plate, one of which is provided with a slide rail and the other with a slider, the slide rail and the slider cooperating; the collection device further includes a third driving member, the third driving member being drivenly connected to the collection module, the third driving member being able to drive the collection module to move in a second direction, so that the slider moves along the slide rail.

[0026] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0027] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0028] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0029] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0030] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0031] This application provides a collection device, such as... Figure 1 As shown, the collection device includes a suction plate 1, such as Figure 2 As shown, the suction plate 1 includes a first surface 11 and a second surface 12 arranged opposite to each other along its own thickness direction Z. Both the first surface 11 and the second surface 12 can adsorb the target object. The target object can be the material formed after the substrate is punched, or it can be the waste material formed during the punching of the substrate. For example, during the punching of the electrode tab on the substrate, the target object is the electrode tab waste. For ease of description, the following will take the electrode tab waste during the punching of the electrode tab as the example.

[0032] In this embodiment, when the target object is electrode waste, after the electrode waste is adsorbed by the suction plate 1, the suction plate 1 can transport the electrode waste to the next process or store it in the collection module 1B, so as to facilitate the secondary use of the electrode waste, thereby improving the material utilization rate. Taking the electrode punching of lithium battery as an example, it improves the utilization rate of electrode substrate, which is conducive to reducing the overall cost of electrode and lithium battery.

[0033] The adsorption of the target object by the suction plate 1 can be vacuum adsorption, electrostatic adsorption, etc. This application embodiment does not specifically limit the adsorption method of the suction plate 1. In this embodiment, such as... Figure 2 As shown, the first surface 11 and the second surface 12 of the suction plate 1 are both provided with a plurality of vacuum adsorption holes 13. The suction plate 1 adsorbs the target object on the surface by the negative pressure in the vacuum adsorption holes 13, and cancels the adsorption effect on the target object by canceling the negative pressure in the vacuum adsorption holes 13, so that the suction plate 1 can switch between adsorption and cancellation of adsorption.

[0034] like Figure 1 As shown, the collecting device also includes a first driving member 2, which is driven to connect with the suction plate 1. The first driving member 2 can drive the suction plate 1 to rotate around the first direction X, so that the first surface 11 or the second surface 12 of the suction plate 1 faces the target object.

[0035] In this embodiment, after the first surface 11 of the suction plate 1 adsorbs the target object, the first driving member 2 can drive the suction plate 1 to rotate, so that the second surface 12 of the suction plate 1 faces the target object. At this time, the first surface 11 can cancel the adsorption of the target object, so that the target object falls into the next process or the collection module 1B. At the same time, the second surface 12 can adsorb the next target object, thereby improving the adsorption efficiency of the suction plate 1 on the target object.

[0036] The first driving component 2 can be a motor, cylinder, etc. The specific structure and type of the first driving component 2 are not specifically limited in the embodiments of this application.

[0037] In one embodiment, such as Figure 3 As shown, the first driving component 2 is directly connected to the suction plate 1 to simplify the connection structure between the first driving component 2 and the suction plate 1, thereby reducing the overall size of the collection device and lowering the cost of the collection device.

[0038] In another embodiment, such as Figure 1 and Figure 4As shown, the collecting device also includes a first connecting rod 3. Along the first direction X, one end of the first connecting rod 3 is connected to the suction plate 1, and the other end of the first connecting rod 3 is driven to be connected to the first driving member 2. That is, the first driving member 2 and the suction plate 1 are indirectly connected through the first connecting rod 3. The first driving member 2 drives the suction plate 1 to rotate around the first direction through the first connecting rod 3. The first direction is perpendicular to the thickness direction of the suction plate 1.

[0039] In this embodiment, the first driving member 2 and the suction plate 1 are indirectly connected by the first connecting rod 3, which helps to increase the distance between the suction plate 1 and the first driving member 2 and to reduce the extension length of the first driving member 2, thereby helping to extend the service life of the first driving member 2 and improve the working stability of the suction plate 1 and the collection device.

[0040] The outline shape of the first connecting rod 3 can be circular or rectangular, or, as shown in the figure. Figure 4 As shown, at least a portion of the outline of the first connecting rod 3 is trapezoidal, that is, one end of the first connecting rod 3 has a larger diameter and the other end has a smaller diameter. The first connecting rod 3 is connected to the first driving member 2 through the end with the larger diameter, thereby improving the connection reliability between the first connecting rod 3 and the first driving member 2. The first connecting rod 3 is connected to the suction plate 1 through the end with the smaller diameter, thereby reducing the required size of the suction plate 1, reducing the cost of the suction plate 1, and at the same time, reducing the weight of the suction plate 1, thereby reducing the difficulty for the first driving member 2 to drive the suction plate 1 to rotate.

[0041] In one embodiment, such as Figure 4 As shown, along the first direction X, one side of the suction plate 1 is directly or indirectly connected to the first driving member 2, while the other side of the suction plate 1 is suspended to simplify the connection structure of the suction plate 1.

[0042] In another embodiment, such as Figure 1 As shown, the collecting device also includes a first fixing plate 4, a second fixing plate 5, and a second connecting rod 6. Along the first direction X, the first fixing plate 4 is located between the first connecting rod 3 and the first driving member 2, and the first connecting rod 3 is rotatably connected to the first fixing plate 4. Along the first direction X, the second fixing plate 5 is located on the side of the suction plate 1 away from the first driving member 2. One end of the second connecting rod 6 is connected to the suction plate 1, and the other end of the second connecting rod 6 is rotatably connected to the second fixing plate 5.

[0043] In this embodiment, a first connecting rod 3 and a second connecting rod 6 are respectively connected to both sides of the suction plate 1, which increases the installation stability of the suction plate 1, reduces the risk of the suction plate 1 tilting, and also reduces the force exerted by the suction plate 1 on the first connecting rod 3, thereby helping to extend the service life of the first connecting rod 3.

[0044] like Figure 1As shown, the collecting device also includes a second driving member 7, which is drivenly connected to the first fixed plate 4, the second fixed plate 5 and the first driving member 2 respectively; the second driving member 7 can drive the first fixed plate 4, the second fixed plate 5 and the first driving member 2 to move synchronously along the thickness direction Z of the suction plate 1, so as to drive the suction plate 1 to move along its own thickness direction Z.

[0045] In this embodiment, the second driving member 7 drives the suction plate 1 to move, which can reduce the distance between the suction plate 1 and the target object in the thickness direction Z of the suction plate 1. This reduces the risk that the target object will fall to the outside of the suction plate 1 and cause the suction plate 1 to fail to adsorb the target object, thereby increasing the accuracy and reliability of the suction plate 1 in adsorbing the target object, and thus improving the working reliability of the collection device.

[0046] In one embodiment, such as Figure 5 As shown, the second driving component 7 is one in number. The collecting device also includes a larger substrate 8. The first fixing plate 4, the second fixing plate 5, and the first driving component 2 are all mounted on the substrate 8. The second driving component 7 is drivenly connected to the substrate 8. The second driving component 7 can drive the substrate 8 to move along the thickness direction Z of the suction plate 1. The substrate 8 drags the first fixing plate 4, the second fixing plate 5, and the first driving component 2 to move synchronously along the thickness direction Z of the suction plate 1. The first fixing plate 4 and the second fixing plate 5 drive the suction plate 1 to move synchronously along its own thickness direction through the first connecting rod 3 and the second connecting rod 6, respectively, so that the suction plate 1 moves closer to or away from the target object. For example, Figure 5 As shown, a through hole 81 is provided on the substrate 8. The target object adsorbed by the suction plate 1 can fall off to the bottom of the substrate 8 through the through hole 81, so as to facilitate the collection of the target object.

[0047] In this embodiment, the second driving member 7 drives the first fixing plate 4, the second fixing plate 5, the first driving member 2 and the suction plate 1 to move synchronously through a base plate 8, which simplifies the connection structure between the second driving member 7 and the first fixing plate 4, the second fixing plate 5 and the first driving member 2, thereby simplifying the overall structure of the collection device.

[0048] In another embodiment, such as Figure 1As shown, the second driving component 7 includes at least a first cylinder 71 and a second cylinder 72. Along the first direction X, the first cylinder 71 and the second cylinder 72 are located on both sides of the suction plate 1. The collecting device also includes a third fixing plate 9 and a fourth fixing plate 1A. The first cylinder 71 is driven to the third fixing plate 9. The first fixing plate 4 and the first driving component 2 are both mounted on the third fixing plate 9. The second cylinder 72 is driven to the fourth fixing plate 1A. The second fixing plate 5 is mounted on the fourth fixing plate 1A. The first cylinder 71 and the second cylinder 72 can drive the third fixing plate 9 and the fourth fixing plate 1A to move synchronously in the thickness direction Z of the suction plate 1, so as to drive the first fixing plate 4, the second fixing plate 5 and the first driving component 2 to move synchronously, thereby driving the suction plate 1 to move synchronously along its own thickness direction Z, so as to make the suction plate 1 approach or move away from the target object.

[0049] In this embodiment, the synchronous movement of the first cylinder 71 and the second cylinder 72 drives the third fixed plate 9 and the fourth fixed plate 1A to move synchronously, thereby realizing the synchronous movement of the first fixed plate 4, the second fixed plate 5, the first driving member 2 and the suction plate 1. This helps to reduce the structure of the third fixed plate 9 and the fourth fixed plate 1A, thereby reducing the material cost of the third fixed plate 9 and the fourth fixed plate 1A, and thus reducing the cost of the collection device. At the same time, it also increases the selectivity of the setting position, quantity and model of the second driving member 7, which is more conducive to improving the working efficiency of the second driving member 7.

[0050] like Figure 1 As shown, the collecting device also includes a collecting module 1B. Along the thickness direction Z of the suction plate 1, the collecting module 1B is located on the side of the suction plate 1 away from the target object. Along the second direction Y, the collecting module 1B can move toward or away from the suction plate 1. The second direction Y is perpendicular to the thickness direction Z of the suction plate 1, and the second direction Y is parallel to the first direction X or has an angle greater than zero. Figure 1 Taking the second direction Y as an example, which is perpendicular to the first direction X.

[0051] In this embodiment, after the suction plate 1 adsorbs the target object, the target object can be stored in the collection module 1B. After a certain number of target objects are stored in the collection module 1B, they are transported together to the next process for packaging or reuse. Temporarily storing the target objects in the collection module 1B can improve the working efficiency of the collection device.

[0052] The collection module 1B is positioned on the side of the suction plate 1 away from the target object. After the target object is adsorbed by the first surface 11 of the suction plate 1, the first driving member 2 can drive the suction plate 1 to rotate around the first direction X, so that the first surface 11 faces the collection module 1B and the second surface 12 faces the next target object. After the first surface 11 releases its adsorption of the target object, the target object falls into the collection module 1B under the action of gravity. At the same time, the second surface 12 adsorbs the next target object. Therefore, by positioning the collection module 1B on the side of the suction plate 1 away from the target object, and in conjunction with the double-sided adsorption function of the suction plate 1, the working efficiency of the collection device can be further improved.

[0053] like Figure 1 As shown, the collection device also includes a fifth fixing plate 1C. One of the fifth fixing plate 1C and the collection module 1B is provided with a slide rail 1C1, and the other is provided with a slider (not shown in the figure). The slide rail 1C1 cooperates with the slider. The collection device also includes a third driving member (not shown in the figure). The third driving member is drivenly connected to the collection module 1B. The third driving member can drive the collection module 1B to move along the second direction Y, so that the slider moves along the slide rail 1C1.

[0054] In this embodiment, when the third driving member drives the collection module 1B to move along the second direction Y, the slider can move along the slide rail 1C1, thereby improving the accuracy of the movement direction of the collection module 1B and also facilitating the control of the movement distance of the collection module 1B.

[0055] like Figure 1 As shown, the collection module 1B includes at least a tray 1B1 and multiple limiting posts 1B2. The limiting posts 1B2 are installed on the tray 1B1. In a plane perpendicular to the thickness direction Z of the suction plate 1, the multiple limiting posts 1B2 are arranged at intervals and form a collection space for accommodating the target object.

[0056] In this embodiment, within the plane containing the first direction X and the second direction Y, the limiting post 1B2 can restrict the movement of the target object on the tray 1B1, thereby reducing the risk of the target object falling off the tray 1B1 and being damaged during the movement of the collection module 1B.

[0057] In one embodiment, such as Figure 1 As shown, the limiting post 1B2 extends along a third direction, which is parallel to the thickness direction Z of the suction plate 1.

[0058] In this embodiment, the third direction is parallel to the thickness direction Z of the suction plate 1, which reduces the difficulty of installing the limiting post 1B2 on the support plate 1B1.

[0059] Alternatively, in one embodiment, such as Figure 6 As shown, the third direction has a greater than zero angle with the thickness direction Z of the suction plate 1.

[0060] In this embodiment, the third direction has an angle greater than zero with the thickness direction Z of the suction plate 1. During the falling process of the target object, the limiting post 1B2 can guide the target object so that the target object can fall accurately into the collection space enclosed by the limiting post 1B2.

[0061] like Figure 1 As shown, the collecting device also includes a punching module 1D, which includes at least a cutter 1D1 and a cutting edge 1D2. Along the thickness direction Z of the suction plate 1, a portion of the cutter 1D1 can be inserted into the cutting edge 1D2 to punch the raw material and form the target object. Along the thickness direction Z of the suction plate 1, the suction plate 1 is located on the side of the cutting edge 1D2 away from the cutter 1D1.

[0062] In this embodiment, the suction plate 1 is located on the side of the blade 1D2 away from the cutter 1D1. After the punching module 1D punches the target object, the target object can fall directly onto the first surface 11 or the second surface 12 of the suction plate 1, thereby reducing the difficulty of the suction plate 1 adsorbing the target object.

[0063] In summary, the working process of the collection device provided in this application embodiment is as follows, taking the punching of electrode tabs and the collection of electrode tab waste as an example:

[0064] S1: Place the electrode substrate on the punching platform 1D3;

[0065] S2: The substrate inside the cutting edge 1D2 is punched to form electrode waste.

[0066] S3: The electrode waste falls onto the first surface 11 of the suction plate 1, and the suction plate 1 adsorbs the electrode waste;

[0067] S4: The first driving component 2 drives the suction plate 1 to rotate around the first direction X, so that the first surface 11 faces the collection module 1B and the second surface 12 faces the punching module 1D;

[0068] S5: The second driving component 7 drives the suction plate 1 to move along its own thickness direction Z, so that the suction plate 1 moves closer to the collection module 1B;

[0069] S6: The first surface 11 of the suction plate 1 stops adsorbing the electrode waste, the electrode waste falls onto the tray 1B1, and the electrode waste is limited in the collection space by the limiting post 1B2;

[0070] S7: The second driving component 7 drives the suction plate 1 to move along its own thickness direction Z, so that the suction plate 1 approaches the punching module 1D;

[0071] S8: The punching module 1D works again, and the electrode waste falls onto the second surface 12 of the suction plate 1;

[0072] S9: The first driving member 2 drives the suction plate 1 to rotate around the first direction X, so that the second surface 12 faces the collection module 1B and the first surface 11 faces the punching module 1D; repeat the above steps S3 to S6 to complete the collection of the tab waste.

[0073] In this embodiment, the suction plate 1 can transport and store the electrode waste in the collection module 1B, so as to facilitate the secondary use of the electrode waste, thereby improving the material utilization rate of the electrode substrate and helping to reduce the cost of the electrode and lithium battery.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
