[0032] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:
[0033] like Figures 1 to 5 As shown, an anti-tab deflection device 10 according to an embodiment of the present disclosure includes a rubber stopper component 100, a first packaging component 200 and a second packaging component 300. The rubber stopper component 100 is provided with a device accommodating channel 1001, a positive tab limiting groove 1002 and a negative tab limiting groove 1003. The extension direction of the positive tab limiting groove 1002 is parallel to the extension direction of the negative tab limiting groove 1003. The device accommodating channel 1001 passes through the rubber stopper component 100 in the thickness direction and is connected to the positive tab limiting groove 1002 and the negative tab limiting groove 1003 in the length direction. The rubber stopper component 100 is located between the first packaging component 200 and the second packaging component 300.
[0034] The first package assembly 200 includes a first package base 210 and a tab flattening member 220 . The second package assembly 300 includes a second package base 310 and a tab separator 320 . The tab flattening member 220 is fixed to the first package base 210 , and the tab separator 320 is fixed to the second package base 310 .
[0035] The tab flattening piece 220 defines a separation groove 2201 , with a first pressing boss 221 and a second pressing boss 222 protruding from both sides of the separation groove 2201 . The end surface of the first pressing boss 221 is parallel to the end surface of the second pressing boss 222 .
[0036] The tab separator 320 is provided with a separation boss 321 , and a first pressing platform 322 and a second pressing platform 323 are provided on both sides of the separation boss 321 . The first pressing boss 221 and the second pressing boss 222 are respectively in contact with the first pressing platform 322 and the second pressing platform 323 .
[0037] Furthermore, the first packaging component 200 and the second packaging component 300 can move relative to each other, so that the tab flattening member 220 and the tab separator 320 are respectively disposed inside the device accommodating channel 1001 .
[0038] In this embodiment, during the process of packaging the battery, the packaging device first places the positive electrode tab and the negative electrode tab of the battery in the positive electrode tab limiting groove 1002 and the negative electrode tab limiting groove 1003 respectively, and then the telescopic motor of the packaging device drives the second packaging component 300 to move vertically upward, so that the partition boss 321 passes through the device accommodating channel 1001 and fills the space between the positive electrode tab and the negative electrode tab. The positive electrode tab is adjacent to one side of the partition boss 321, and the part located in the device accommodating channel 1001 abuts against one side of the partition boss 321. The negative electrode tab is adjacent to one side of the partition boss 321, and the part located in the device accommodating channel 1001 abuts against the other side of the partition boss 321, so that the positive electrode tab and the negative electrode tab are stretched apart by the partition boss 321, and the positive electrode tab and the negative electrode tab are respectively fixed in the positive electrode tab limiting groove 1002 and the negative electrode tab limiting groove 1003.
[0039] Furthermore, the telescopic motor of the packaging device drives the first packaging component 200 to move vertically downward, the first crimping boss 221 and the second crimping boss 222 are arranged in the device accommodating channel 1001, the separation boss 321 abuts against the separation groove 2201, and the first crimping boss 221 abuts against the first crimping platform 322, and the second crimping boss 222 abuts against the second crimping platform 323, so that the positive electrode tab is tightly fixed between the first crimping boss 221 and the first crimping platform 322, and the negative electrode tab is tightly fixed between the second crimping boss 222 and the second crimping platform 323. Between the crimping platforms 323; after the separation boss 321 abuts against the separation groove 2201, since the first packaging component 200 and the second packaging component 300 are relatively arranged and can move relative to each other, the telescopic motor of the packaging equipment drives the second packaging component 300 to move vertically upward, and then drives the first packaging component 200 to move vertically downward, which will make the first packaging component 200 and the second packaging component 300 abut against each other at the top sealing part of the battery. Finally, the packaging equipment heats the first packaging component 200 and the second packaging component 300 to complete the packaging process of the battery.
[0040] In the above-mentioned device 10 for preventing the tab from tilting, during the process of packaging the battery, the partition boss 321 is passed through the device accommodating channel 1001, filling the space between the positive tab and the negative tab, so that the positive tab is adjacent to one side of the partition boss 321, and the negative tab is adjacent to one side of the partition boss 321, and is respectively stretched apart by the partition boss 321, and the positive tab and the negative tab are respectively fixed in the positive tab limiting groove 1002 and the negative tab limiting groove 1003, thereby preventing the positive tab and the negative tab from tilting during the packaging process.
[0041] Furthermore, driven by the telescopic motor, the first crimping boss 221 and the second crimping boss 222 of the tab flattening member 220 are inserted into the device accommodating channel 1001, and the positive tab and the negative tab on the first crimping platform 322 and the second crimping platform 323 are flattened and fixed, thereby further preventing the positive tab and the negative tab from being skewed during the packaging process. At the same time, it can also prevent the positive tab and the negative tab from being bent or folded during the packaging process, thereby improving the pass rate of the anti-tab skew device 10 during the packaging process.
[0042] like Figure 5As shown, in one embodiment, the top of the separating boss 321 is a wedge-shaped structure, and the separating boss 321 is adapted to the outer contour of the separating groove 2201. In this embodiment, due to the wedge-shaped structure of the top of the separating boss 321, the cross-section of the top of the separating boss 321 gradually increases from the top to the sides, forming an inclined surface. During the insertion of the separating boss 321 into the separating groove 2201, the presence of the inclined surface can prevent the sidewalls of the separating boss 321 from colliding with the positive and negative electrode tabs, thereby preventing the positive and negative electrode tabs from warping during the packaging process.
[0043] like Figure 1 As shown, in one embodiment, the top of the first packaging base 210 includes a first abutting portion 211, and the top of the second packaging base 310 includes a second abutting portion 311, with the first abutting portion 211 and the second abutting portion 311 being disposed opposite each other. In this embodiment, the telescopic motor of the packaging device first drives the second packaging base 310 to move vertically upward, allowing the separation boss 321 to insert into the separation groove 2201, and then drives the first packaging base 210 to move vertically downward, causing the first crimping boss 221 and the second crimping boss 222 of the tab flattening member 220 to abut the first crimping platform 322 and the second crimping platform 323 on the tab separator 320, respectively. Simultaneously, the first abutting portion 211 and the second abutting portion 311 abut against each other in the battery's top sealing area. Because the width of the abutment between the first abutting portion 211 and the second abutting portion 311 is smaller than the width of the battery tab insulation adhesive, the packaging device can accurately complete the packaging process in the battery's top sealing area.
[0044] like Figure 1 and Figure 3 As shown, in one embodiment, the first packaging component 200 also includes a first fixing bolt 230, the tab flattening piece 220 is provided with a first bolt hole 2202, and the first fixing bolt 230 threadably connects the tab flattening piece 220 to the first packaging component 200 through the first bolt hole 2202, and the second packaging component 300 also includes a second fixing bolt 330, the tab separator 320 is provided with a second bolt hole 3201, and the second fixing bolt 330 threadably connects the tab separator 320 to the second packaging component 300 through the second bolt hole 3201. In this embodiment, since the tab flattening piece 220 is fixed to the first packaging base 210 by the first fixing bolt 230, and the tab separator 320 is fixed to the second packaging base 310 by the second fixing bolt 330, when the first packaging component 200 and the second packaging component 300 abut against each other, the separation boss 321 of the tab separator 320 and the separation groove 2201 of the tab flattening piece 220 can accurately abut against each other, thereby improving the accuracy of the tab deflection prevention device 10 during the packaging process.
[0045] like Figure 1 As shown, in one embodiment, the first packaging base 210 and the second packaging base 310 are respectively provided with a first base mounting hole 2101 and a second base mounting hole 3101, which are respectively used to connect to the output end of the first telescopic motor and the output end of the second telescopic motor of the packaging device. In this embodiment, since the first packaging base 210 is connected to the output end of the first telescopic motor through the first base mounting hole 2101, and the second packaging base 310 is connected to the output end of the second telescopic motor through the second base mounting hole 3101, during the packaging process of the packaging device packaging the battery, the first packaging assembly 200 and the second packaging assembly 300 can be firmly connected to the first telescopic motor and the second telescopic motor, thereby preventing the first packaging base 210 and the second packaging base 310 from deviating during the packaging process, thereby improving the accuracy of the anti-tab skew device 10 during the packaging process.
[0046] like Figure 2 As shown, in one embodiment, the rubber blocking assembly 100 includes a front rubber blocking strip 110 and a rear positioning block 120, the rear positioning block 120 is provided with a positive ear limiting groove 1002 and a negative ear limiting groove 1003, the front rubber blocking strip 110 is provided with a positive ear groove 1101 and a negative ear groove 1102, the positive ear limiting groove 1002 is connected to the positive ear groove 1101, the negative ear limiting groove 1003 is connected to the negative ear groove 1102, and the device accommodating channel 1001 is arranged between the front rubber blocking strip 110 and the rear positioning block 120. In this embodiment, during the process of placing the positive electrode tab and the negative electrode tab, the positive electrode tab and the negative electrode tab are first respectively passed through the positive electrode tab groove 1101 and the negative electrode tab groove 1102, and then the positive electrode tab and the negative electrode tab pass through the device accommodating channel 1001 and are respectively fixed in the positive electrode tab limiting groove 1002 and the negative electrode tab limiting groove 1003. Since the positive electrode tab groove 1101 and the positive electrode tab limiting groove 1002 are arranged in parallel with each other, and the negative electrode tab groove 1102 and the negative electrode tab limiting groove 1003 are arranged in parallel with each other, the positive electrode tab and the negative electrode tab can be accurately fixed in the positive electrode tab limiting groove 1002 and the negative electrode tab limiting groove 1003, thereby avoiding the positive electrode tab and the negative electrode tab from being skewed and offset in the rubber blocking assembly 100.
[0047] like Figure 2As shown, in one embodiment, the extension direction of the device accommodating channel 1001 is perpendicular to the extension direction of the positive tab limiting groove 1002 and the negative tab limiting groove 1003. In this embodiment, since the device accommodating channel 1001 passes through the rubber stopper assembly 100, and the extension direction of the device accommodating channel 1001 is perpendicular to the extension direction of the positive tab limiting groove 1002 and the negative tab limiting groove 1003, it is conducive to the accurate insertion of the tab separator 320 and the tab flattening member 220 into the device accommodating channel 1001, avoiding the problem of the packaging equipment crushing the rubber stopper assembly 100 due to the inaccurate position of the device accommodating channel 1001, thereby improving the stability of the anti-tab skew device 10.
[0048] like Figure 2 As shown, in one embodiment, the front blocking rubber strip 110 includes a avoidance block 111, which is integrally connected to a side wall of the front blocking rubber strip 110 that is away from the rear positioning block 120. The avoidance block 111 is located between the positive ear groove 1101 and the negative ear groove 1102, and a positive insulating rubber avoidance groove 1103 and a negative insulating rubber avoidance groove 1104 are respectively provided on both sides of the avoidance block 111. In this embodiment, since a layer of positive ear insulation glue and a layer of negative ear insulation glue are respectively arranged between the positive ear and the negative ear of the battery and the aluminum-plastic film, when the positive ear and the negative ear are placed in the glue blocking assembly 100, the positive electrode insulation glue avoidance groove 1103 and the negative electrode insulation glue avoidance groove 1104 can prevent the positive ear insulation glue and the negative ear insulation glue from abutting against the front glue blocking strip 110, thereby avoiding the positive ear and the negative ear from bending or warping due to the abutment of the insulation glue against the front glue blocking strip 110, thereby ensuring that the positive ear and the negative ear can be accurately placed in the glue blocking assembly 100.
[0049] like Figure 2 As shown, in one embodiment, the rubber stopper assembly 100 is further provided with a waist-shaped fixing through-hole 1004, and the waist-shaped fixing through-hole 1004 is located on one side of the rear positioning block 120. In this embodiment, the rubber stopper assembly 100 is fixed to the packaging device via the waist-shaped fixing through-hole 1004 bolts. Since the two ends of the waist-shaped fixing through-hole 1004 are symmetrical circles, the middle is processed to form a long hole parallel to the axis of the waist-shaped fixing through-hole 1004, thereby forming a long strip-shaped hole with semicircular ends and a straight line in the middle. When the rubber stopper assembly 100 is fixed to the packaging device, the fastening bolts can be fixed at different positions in the middle part of the waist-shaped fixing through-hole 1004, so that the rubber stopper assembly 100 can adjust its position according to the shape of different batteries, thereby improving the flexibility of the tab deflection prevention device 10.
[0050] A battery packaging device comprises any one of the above-mentioned tab deflection preventing devices 10. In this embodiment, during the process of packaging the battery, the packaging device first places the positive electrode tab and the negative electrode tab of the battery in the positive electrode tab limiting groove 1002 and the negative electrode tab limiting groove 1003 respectively, and then the telescopic motor of the packaging device drives the second packaging component 300 to move vertically upward, so that the partition boss 321 passes through the device accommodating channel 1001 and fills the space between the positive electrode tab and the negative electrode tab. The positive electrode tab is adjacent to one side of the partition boss 321, and the part located in the device accommodating channel 1001 abuts against one side of the partition boss 321. The negative electrode tab is adjacent to one side of the partition boss 321, and the part located in the device accommodating channel 1001 abuts against the other side of the partition boss 321, so that the positive electrode tab and the negative electrode tab are stretched apart by the partition boss 321, and the positive electrode tab and the negative electrode tab are respectively fixed in the positive electrode tab limiting groove 1002 and the negative electrode tab limiting groove 1003. Furthermore, the telescopic motor of the packaging device drives the first packaging component 200 to move vertically downward, the first crimping boss 221 and the second crimping boss 222 are arranged in the device accommodating channel 1001, the separation boss 321 abuts against the separation groove 2201, and the first crimping boss 221 abuts against the first crimping platform 322, and the second crimping boss 222 abuts against the second crimping platform 323, so that the positive electrode tab is tightly fixed between the first crimping boss 221 and the first crimping platform 322, and the negative electrode tab is tightly fixed between the second crimping boss 222 and the second crimping platform 323. Between the crimping platforms 323; after the separation boss 321 abuts against the separation groove 2201, since the first packaging component 200 and the second packaging component 300 are relatively arranged and can move relative to each other, the telescopic motor of the packaging equipment drives the second packaging component 300 to move vertically upward, and then drives the first packaging component 200 to move vertically downward, which will make the first packaging component 200 and the second packaging component 300 abut against each other at the top sealing part of the battery. Finally, the packaging equipment heats the first packaging component 200 and the second packaging component 300 to complete the packaging process of the battery.
[0051] Compared with the prior art, the present disclosure has at least the following advantages:
[0052] 1. In the above-mentioned anti-tab skew device 10, during the battery packaging process, the partition boss 321 is inserted into the device accommodating channel 1001, filling the space between the positive tab and the negative tab, so that the positive tab is adjacent to one side of the partition boss 321, and the negative tab is adjacent to one side of the partition boss 321, and is respectively supported by the partition boss 321, and the positive tab and the negative tab are respectively fixed in the positive tab limiting groove 1002 and the negative tab limiting groove 1003, thereby preventing the positive tab and the negative tab from skewed during the packaging process.
[0053] 2. Driven by the telescopic motor, the first crimping boss 221 and the second crimping boss 222 of the tab flattening member 220 are inserted into the device accommodating channel 1001, and flatten and fix the positive tab and the negative tab on the first crimping platform 322 and the second crimping platform 323, thereby further preventing the positive tab and the negative tab from being skewed during the packaging process. At the same time, it can also prevent the positive tab and the negative tab from being bent or folded during the packaging process, thereby improving the qualified rate of the anti-tab skew device 10 during the packaging process.
[0054] The above-described embodiments merely represent several implementation methods of the present disclosure.
