Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to the field of lithium battery technology. More specifically, the present disclosure relates to a vacuum suction positioning device for tab taping and a vacuum suction positioning device assembly. BACKGROUND

[0002] In a battery, a tab is a metal conductor that is drawn from the battery tab. The aforementioned metal conductor is fixed to the battery tab by welding or bonding. The current generated by the tab needs to be led out to the external circuit. As an extension of the electrode, the tab provides a low-resistance channel to effectively conduct the current generated by the electrochemical reaction inside the battery to the externally connected circuit. In addition, the tab is the interface for connecting the battery to external devices (such as circuit boards, chargers, electrical devices, etc.). Its structural design allows the battery to be easily mechanically and electrically connected to various external circuits.

[0003] In the manufacturing process of lithium ion batteries, tab taping is a key step. Specifically, tab taping can fix the shape of the cell and prevent deformation during subsequent battery packaging and use, thereby ensuring the structural stability of the battery. In addition, tab taping can also prevent the tab and the burrs on the tab from piercing the separator and causing short circuits when used improperly, thereby improving the safety performance of the battery. Tab taping provides insulation protection to prevent short circuits between the metal strip and the aluminum plastic film, and is bonded together with the aluminum plastic film by heating and hot melting during packaging to prevent liquid leakage.

[0004] When tab taping is performed, the length of the cut tape can be greater than the corresponding size of the tab to ensure that it can cover the edges of the tab. However, when using a taping head to tape the tab, the taping head cannot fix and press the two ends of the tape, which can easily cause the tape to fall off. Further, the size of the related taping head cannot be adjusted, so the same taping head cannot be compatible with tabs of different sizes. When the size of the tab changes, a new taping head needs to be replaced, which can result in higher costs and low efficiency.

[0005] Therefore, there is an urgent need to provide a vacuum suction positioning device for tab taping and a vacuum suction positioning device assembly, which can fix and press the two ends of the tape, can avoid the tape from falling off, and can avoid the tab from contacting the surrounding conductors to cause short circuits. In addition, when the size of the tab changes, the structure of the vacuum suction positioning device of the present disclosure can also be adjusted accordingly to tape the tab with a changed size, and the efficiency of taping can also be improved.

[0028] The specific embodiments disclosed herein will now be described in detail with reference to the accompanying drawings.

[0029] Figure 1 A perspective view of a vacuum adsorption positioning device for tab bonding, according to some embodiments of this disclosure, is shown. Figure 1 As shown, the vacuum adsorption positioning device includes: a first adhesive suction block 10; wherein, the first side 11 of the first adhesive suction block 10 includes a first region 12 and a second region 13; a first through hole 110 with an axis perpendicular to the first side 11 is provided on the first region 12, and a first pressing block 111 is provided in the first through hole 110, and the first pressing block 111 can move along the axial direction of the first through hole 110; one or more first suction ports 131 are provided on the second region 13.

[0030] In some embodiments, when the adhesive tape is applied, the first side 11 of the first adhesive block 10 faces the tab, the projection of the second region 13 in the direction perpendicular to the first side 11 is located on the tab, and the projection of the first region 12 in the direction perpendicular to the first side 11 is located outside the tab.

[0031] In some embodiments, the aforementioned tab can be a metal conductor led out from the battery tab. The aforementioned tab can be fixed to the battery tab by welding or bonding. The current generated by the tab needs to be led out to the external circuit, and the tab can serve as an extension of the electrode, providing a low-resistance channel to effectively conduct the current generated by the electrochemical reaction inside the battery to the externally connected circuit. In addition, the tab is the interface for the battery to connect with external devices. Its structural design enables the battery to be easily mechanically and electrically connected to various external circuits.

[0032] In some embodiments, when the tab needs to be taped, the adhesive tape can be first adsorbed on the surface of the vacuum adsorption positioning device. Specifically, the aforementioned vacuum adsorption positioning device can be based on the principle of vacuum adsorption, and a small vacuum system can be provided inside the aforementioned vacuum adsorption positioning device. When the adhesive tape needs to be adsorbed, the vacuum channel is opened, so that the air pressure inside the vacuum adsorption positioning device is rapidly reduced, which is lower than the atmospheric pressure outside. According to the principle of air pressure difference, the adhesive tape will be adsorbed on the surface of the vacuum adsorption positioning device.

[0033] In some embodiments, the shape of the aforementioned vacuum adsorption positioning device can be circular, square or other shapes. It can be understood that the shape of the aforementioned vacuum adsorption positioning device can be selected according to the size of the tab. For example, when the size of the aforementioned tab is small, the shape of the aforementioned vacuum adsorption positioning device can be circular, so that sufficient adsorption force can be generated on a smaller contact area to adsorb the adhesive tape. When the size of the aforementioned tab is large, the shape of the aforementioned vacuum adsorption positioning device can be rectangular, which can provide more uniform adsorption force distribution and prevent the adhesive tape from being locally raised or detached. It can be understood that the shape of the aforementioned vacuum adsorption positioning device can be correspondingly set according to the size and shape of the tab, which can improve the adsorption effect and stability.

[0034] In some embodiments, the first side 11 of the first adhesive block 10 can be the side facing the tab, and the first side 11 can include a first region 12 and a second region 13.

[0035] In some embodiments, the first region 12 can be provided with a first pressing block 111, and a tape can be provided between the first pressing block 111 and the tab, so that the tape on the edge of the tab can be fixed together by extrusion. It can be understood that, in the direction perpendicular to the tab, the projection of the first pressing block 111 on the plane where the tab is located can be located outside the tab, and the edge of the projection can coincide with the edge of the tab. When the edge of the projection coincides with the edge of the tab, when the first pressing block 111 moves in the direction perpendicular to the tab, the side of the first pressing block 111 can continue to move downward along the edge of the tab, so that the edge of the tab can be adhered with the tape.

[0036] In some embodiments, a stage or a symmetrical pressing block can be provided below the tab, and the symmetrical pressing block can be symmetrically provided with the first pressing block 111 with respect to the tab. When the first pressing block drives the tape to move in the direction perpendicular to the tab, the first pressing block can extrude the tab together with the stage or the second pressing block, so that the tab can be adhered with the tape.

[0037] It can be understood that, one side of the first pressing block 111 towards the tab can be a first side of the first pressing block, and the other side of the first pressing block 111 away from the tab can be a second side of the first pressing block, the second side of the first pressing block can be connected with a vacuum component, and the vacuum component can provide negative pressure, so that the first pressing block 111 is adsorbed into the first through hole 110. When the tape needs to be sucked, the vacuum component can provide negative pressure to suck the first pressing block 111 into the first through hole 110.

[0038] In some embodiments, the second side of the first pressing block can also be connected with a spring. When the vacuum component provides negative pressure and sucks the first pressing block 111 into the first through hole 110, the spring can be in a compressed state; when the vacuum component stops providing negative pressure, the spring in the compressed state can be bounced out and bounce the first pressing block 111 out, and extrude the tape to the side of the tab.

[0039] In some embodiments, one or more first suction ports 131 can be formed on the second region 13, and the plurality of first suction ports 131 can be arranged in an array (for example, arranged in a rectangle or a circle, etc.).

[0040] In some embodiments, the projection of the second region 13 in the direction perpendicular to the tab can coincide with the tab, when the first pressing block 10 needs to adhere the tape, the first pressing block 10 can move towards the tab and drive the tape to move towards the tab. When the tape moves to the position adhered with the tab, at this time, the vacuum component can stop providing negative pressure, so that the tape can be adhered to the surface of the tab.

[0041] Through the arrangement of the first glue suction block, the two ends of the adhesive tape can be fixed and pressed, so that the adhesive tape can be prevented from falling off, and the problem of short circuit caused by the contact between the tab and the surrounding conductive body can be avoided.

[0042] Figure 2 A schematic diagram of a vacuum suction positioning device including a first glue pressing block and a second glue pressing block is shown. As Figure 2 shown, in some embodiments, the vacuum suction positioning device further includes a second glue suction block 20, a side of the second glue suction block 20 is movably connected with a side of the first glue suction block 10, and the side of the second glue suction block 20 can move in a direction parallel to the first side 11; wherein the second glue suction block 20 includes a third area 21 and a fourth area 22, wherein the third area 21 is an area away from the first glue suction block 10, and the fourth area 22 is an area close to the first glue suction block 10; the third area 21 is provided with a second through hole 210 with an axis perpendicular to the first side 11, and the second through hole 210 is provided with a second glue pressing block 211, the second glue pressing block 211 is movably connected with the second through hole 210, and can move along the axis direction of the second through hole 210; the fourth area 22 is provided with one or more second suction ports 231.

[0043] In some embodiments, the aforementioned vacuum suction positioning device can include a first glue suction block 10 and a second glue suction block 20. The side of the first glue suction block 10 can be movably connected with the side of the second glue suction block 20. Specifically, the side of the first glue suction block 10 facing the second glue suction block 20 can be a second side 102 of the first glue suction block, the side of the second glue suction block 20 facing the first glue suction block 10 can be a second side 24 of the second glue suction block, and the side of the second glue suction block 20 facing the tab can be a first side 23 of the second glue suction block.

[0044] In some embodiments, the first side 102 of the first glue suction block can be provided with a first opening, the second side 24 of the second glue suction block can be provided with a second opening opposite to the first opening, and the vacuum suction positioning device can further include a first connecting rod 25, one end of the first connecting rod 25 can be located in the first opening and movably connected with the first opening. The other end of the first connecting rod 25 can be located in the second opening and movably connected with the second opening.

[0045] It can be understood that, through the arrangement of the aforementioned connecting rod, the aforementioned first glue suction block 10 and the second glue suction block 20 can reciprocate along the first connecting rod, so that the distance between the first glue suction block 10 and the second glue suction block 20 can be adjusted. When the size of the tab changes, the operation of gluing the new tab can be realized by adjusting the distance between the first glue suction block 10 and the second glue suction block 20.

[0046] In some embodiments, the aforementioned third area 21 can be provided with a second glue pressing block 211, and the aforementioned second glue pressing block 211 and the tab can be provided with a tape, so that the tape on the edge of the tab can be fixed together by extrusion. It can be understood that, along the direction perpendicular to the tab, the projection of the second glue pressing block 211 on the plane where the tab is located can be located outside the tab, and the edge of the aforementioned projection can also coincide with the edge of the tab. When the edge of the projection coincides with the edge of the tab, when the second glue pressing block 211 moves along the direction perpendicular to the tab, the side of the aforementioned second glue pressing block 211 can continue to move downward along the edge of the tab, so that the edge of the tab can be glued with the tape.

[0047] In some embodiments, the aforementioned second through hole 210 can be provided with a limiting block 2101, and the aforementioned limiting block can be provided with a limiting block through hole along the direction perpendicular to the tab. The end of the aforementioned second glue pressing block 211 towards the tab can be a second glue pressing block first end 2111, and the end of the aforementioned second glue pressing block 211 away from the tab can be a second glue pressing block second end 2112. In some embodiments, the aforementioned second glue pressing block 211 can be arranged in a stepped shape, and the size of the aforementioned second glue pressing block second end 2112 can be greater than the size of the aforementioned second glue pressing block first end 2111. Specifically, the size of the aforementioned second glue pressing block first end 2111 can be equal to or less than the size of the limiting block through hole, and the aforementioned second glue pressing block first end 2111 can penetrate through the aforementioned limiting block through hole. The size of the aforementioned second glue pressing block second end 2112 can be greater than the size of the aforementioned limiting block through hole, and the aforementioned second glue pressing block second end 2112 can abut against the aforementioned limiting block 2101, thereby achieving limiting.

[0048] In some embodiments, the projection of the aforementioned fourth area 22 along the direction perpendicular to the tab can coincide with the tab. In some embodiments, the aforementioned fourth area 22 can form one or more second suction ports 231, and the aforementioned plurality of second suction ports 231 can be arranged in an array. The aforementioned second suction port can suction the tape to the second glue pressing block 211.

[0049] By setting up the first adhesive suction block 10 and the second adhesive suction block 20, the two ends of the adhesive tape can be fixed and pressed tightly, preventing the tape from falling off and thus avoiding contact between the tab and surrounding conductors, which could cause a short circuit. Furthermore, when the size of the tab changes due to replacing different batches, the structure of the vacuum adsorption positioning device disclosed herein can be adjusted accordingly to apply adhesive to the tab after the size change, thereby improving the efficiency of the adhesive application.

[0056] In some embodiments, the third side of the third glue suction block 30 can be provided with one or more third openings. It can be understood that the first opening, the second opening, and the third opening are inside.

[0057] An air suction pipe can be provided to suck the adhesive tape. In some embodiments, electromagnetic suction devices, electrostatic suction devices, vacuum suction devices, etc. can also be used. Preferably, a vacuum suction device can be selected. One end of the aforementioned vacuum suction device can be connected to a vacuum generator or a negative pressure device through a pipe.

It can be understood that the first pressing block 111 can be connected with the first pipe, which can reduce the arrangement of the vacuum component, thereby reducing the size of the device. In some embodiments, when the vacuum component provides negative pressure and sucks the first pressing block 111 into the first through hole 110, the spring can be in a compressed state; when the vacuum component does not provide negative pressure, the spring in the compressed state can be ejected and the first pressing block 111 can be ejected, thereby the pressing plate 113 can be ejected and the adhesive tape can be squeezed onto the side of the tab.

[0063] In some embodiments, the first adhesive block 10 is further provided with a second pipe connected with the first pressing block, for providing suction force to the first pressing block 111 to drive the first pressing block 111 to move in a direction perpendicular to the first side 11.

[0064] In some embodiments, the first adhesive block 10 can be provided with a vacuum component, and the first pressing block 111 can share a pipe with the first opening. Specifically, one end of the first pressing block 111 can be connected with the first pipe, and the first pressing block 111 can use the same vacuum component with the first opening, which can reduce the waste of space.

[0065] In some embodiments, the first adhesive block 10 can be further provided with a plurality of vacuum components, which can include a first vacuum component and a second vacuum component. Specifically, the first opening can be connected with the first vacuum component through the first pipe, and the first pressing block 111 can be connected with the second vacuum component through the second pipe. It can be understood that when the size of the adhesive tape is large and the weight is heavy, the first opening needs to provide a larger suction force to adsorb the adhesive tape. At this time, the first pressing block 111 and the first opening can independently use different vacuum components to provide a larger suction force.

[0066] Through the arrangement of the second pipe, the stability of the adsorbed adhesive tape can be ensured when the adhesive tape is heavy, and the situation of falling due to insufficient suction force can be avoided.

[0067] In some embodiments, the aforementioned vacuum adsorption positioning device further comprises a connecting plate 40, a first end of the connecting plate is movably connected with the first suction block 10, a second end of the connecting plate 40 is connected with the second suction block 20, and a third end of the connecting plate 40 is movably connected with the third suction block 30, wherein the second end of the connecting plate 40 is located between the first end of the connecting plate 40 and the third end of the connecting plate 40.

[0068] In some embodiments, the aforementioned connecting plate 40 can connect the first suction block 10, the second suction block 20 and the third suction block 30, so as to avoid the dislocation of the adhesive tape or the gap between the adhesive tape and the tab caused by unstable connection of the suction blocks during the gluing.

[0069] In some embodiments, the present disclosure further provides a vacuum adsorption positioning device assembly for tab gluing, wherein the vacuum adsorption positioning device comprises a first vacuum adsorption positioning device and a second vacuum adsorption positioning device, the first vacuum adsorption positioning device and the second vacuum adsorption positioning device are any one of the vacuum adsorption positioning devices for tabs disclosed in the present disclosure, and the tab can be located between the first vacuum adsorption positioning device and the second vacuum adsorption positioning device, wherein the first vacuum adsorption positioning device and the second vacuum adsorption positioning device are symmetrically arranged along the tab.

[0070] Through the design of the aforementioned vacuum adsorption positioning device assembly, the two ends of the adhesive tape can be fixed and compressed, and the adhesive tape can be prevented from falling off, so as to avoid the problem of short circuit caused by the contact between the tab and the surrounding conductive body. In addition, when the size of the tab changes due to the replacement of different batches of tabs, the structure of the vacuum adsorption positioning device of the present disclosure can also be adjusted accordingly to glue the tab with changed size, which can improve the gluing efficiency.

[0071] Although the embodiments of the present disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided only by way of example. Many modifications, changes and alternative ways can be conceived by those skilled in the art without departing from the spirit and scope of the present disclosure. It should be understood that various alternatives to the embodiments of the present disclosure described herein can be employed in practicing the present disclosure. The appended claims are intended to define the scope of protection of the present disclosure and thus cover the equivalents or alternatives within the scope of the claims.
