Description

Technical Field

[0001] The invention belongs to the field of lithium battery processing and assembly, and specifically relates to an automatic processing and assembly machine for lithium batteries. Background Art

[0002] The processing and assembly of lithium batteries includes multiple steps. One of the steps requires placing an insulating plate between every two lithium battery plates to provide isolation between the lithium battery plates to prevent direct contact and short circuit of the electrolytes. The electrolyte between the positive and negative poles of the lithium battery is transmitted through the micropores or coating on the insulating plate. This can effectively isolate the electrolyte and prevent the flow of abnormal current, thereby ensuring the safety and stability of the battery. Therefore, an insulating plate will be stacked on a lithium battery plate through an automatic multi-axis robot, and then a lithium battery plate will be stacked on this insulating plate, and so on, to complete the assembly of the insulating plate and lithium battery plate.

[0003] A patent document with publication number CN212676383U discloses a lithium battery rapid assembly and fixing device, including a fixing plate, a pressure plate provided on one side of the fixing plate, an insulating rubber plate provided between the pressure plate and the fixing plate, the fixing plate and the pressure plate being sleeved on both ends of the lithium battery, the ends of the lithium battery resting on the insulating rubber plate, and a surrounding plate provided on the outside of the lithium battery, with both ends of the surrounding plate resting on the pressure plate. The fixing plate, insulating rubber plate, and pressure plate are assembled in sequence, multiple lithium batteries are placed side by side against the bosses on the insulating rubber plate, the surrounding plate is placed on the bottom pressure plate, and the assembled fixing plates at both ends of the lithium battery are connected by a screw rod. The screw rod is adjusted so that the two ends of the lithium battery fully rest against and stretch the bosses of the insulating rubber plate to form a seal, and then filler is introduced into the feed port of the surrounding plate for reinforcement and protection.

[0004] In the traditional technical solution, glue is applied to the middle part of the lithium battery plate and the insulating plate, and then the plates are clamped and stacked one by one by an automatic robot. First, a lithium battery plate is placed on the assembly mechanism, and then an insulating plate is stacked on this lithium battery plate. The colloid between the two can stabilize the connection between the lithium battery plate and the insulating plate. Another lithium battery plate is stacked on this insulating plate, and so on to complete the assembly of the insulating plate and the lithium battery plate. In this process, the plates need to be clamped and stacked one by one, which takes a lot of time and affects the processing and assembly time of the lithium battery.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The automatic processing and assembly machine for lithium batteries described in the present invention clamps multiple lithium battery blocks through a clamping arm, and then uses a gluing machine to apply glue at the center position above the multiple lithium battery blocks. Subsequently, the multiple lithium battery blocks are inserted into the position between multiple stacked components through the clamping arm, and the lowest lithium battery block is inserted into the position between the bottom of the mechanism's I-plate and the stacked components.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Example 1

[0036] like Figure 1-4 As shown, an automatic processing and assembly machine for lithium batteries according to an embodiment of the present invention includes a multi-axis machine 2 and a clamping arm 21 installed on the side of the multi-axis machine 2. A base 1 is fixedly installed on the side of the multi-axis machine 2. A lifting platform 11 is installed above the base 1 through a lifting structure. An angle adjustment member 12 is movably installed inside the lifting platform 11. A battery assembly platform 3 is movably installed above the lifting platform 11. The battery assembly platform 3 is connected to the angle adjustment member 12. The battery assembly platform 3 includes a mechanism I-shaped plate 4 and two first sliding plates 5 and a second sliding plate 6 slidably installed inside the mechanism I-shaped plate 4. The distance between the two first sliding plates 5 is greater than the distance between the two second sliding plates 6. A superimposed member 7 is installed on the side of the first sliding plate 5.

[0037] The stacking member 7 includes an upper supporting plate 8 and a lower supporting plate 9 mounted on the sides of the first sliding plate 5. A plurality of through slots 62 are formed in the interior of the two second sliding plates 6. An electrically driven rotating plate 61 is movably mounted on the side of one of the second sliding plates 6. One end of the upper supporting plate 8 and the lower supporting plate 9 extends through the corresponding through slots 62 to a position between the two second sliding plates 6.

[0038] An insulating plate 41 is placed between the upper supporting plate 8 and the lower supporting plate 9 , and a lithium battery block 42 is placed between the two stacked components 7 .

[0039] Specifically, the multi-axis machine 2 clamps a plurality of lithium battery blocks 42 through the clamping arm 21, and then performs glue coating at the center position above the plurality of lithium battery blocks 42 through the glue coating machine, and then inserts the plurality of lithium battery blocks 42 into the position between the plurality of stacked components 7 through the clamping arm 21, and the bottom lithium battery block 42 is inserted into the position between the bottom of the mechanism I-shaped plate 4 and the stacked component 7. The plurality of insulating plates 41 are clamped and glued in the same way, and the clamping arm 21 can insert the plurality of insulating plates 41 into the plurality of stacked components 7. The spacing between the upper supporting plate 8 and the lower supporting plate 9 is smaller than the spacing between the two upper supporting plates 8 at the same level. The gluing positions of the insulating plate 41 and the lithium battery block 42 are between the two upper supporting plates 8 at the same level. Therefore, when the insulating plate 41 and the lithium battery block 42 are inserted into the battery assembly table 3, the colloid will not be affected. After the lithium battery block 42 and the insulating plate 41 are both inside the battery assembly table 3, they are simultaneously pushed outwards of the mechanism I-shaped plate 4 through the two first sliding plates 5. The stacking members 7 are moved sideways, that is, the distance between the two first sliding plates 5 is increased. The movement of the first sliding plates 5 drives the multiple stacking members 7 to move until the stacking members 7 move to the limit. At this time, there are no multiple stacking members 7 between the two second sliding plates 6. Without the stacking members 7 as partitions, the multiple lithium battery blocks 42 and the insulating plates 41 will be stacked together under the action of gravity. By stacking the multiple insulating plates 41 and the lithium battery blocks 42 at the same time, the processing and assembly efficiency of the lithium battery is accelerated. At this time, the multiple insulating plates 41 and the lithium battery blocks 42 will be initially fixed together by the colloid. Under electric drive, the two second sliding plates 6 move toward each other, narrowing the distance between them, and clamping the multiple insulating plates 41 and the lithium battery blocks 42. The electrically driven rotating plate 61 can be rotated toward the mechanism I-shaped plate 4 under electric drive until it is squeezed with the multiple insulating plates 41 and the lithium battery blocks 42. In this way, the multiple insulating plates 41 and the lithium battery blocks 42 are stacked neatly. After a period of time, the colloid cools, and the automatic processing and assembly of the insulating plates 41 and the lithium battery blocks 42 is completed.

[0040] like Figure 5-7As shown, the upper supporting plate 8 includes a first horizontal plate 81 fixedly mounted on the side of the first sliding plate 5 and a rotating member 83 mounted on the side of the first horizontal plate 81. The first horizontal plate 81 is connected to the first rotating plate 82 through the rotating member 83. Two connecting ropes 84 are installed on the other side of the first horizontal plate 81. The two connecting ropes 84 are located inside the first sliding plate 5. The lower supporting plate 9 and the upper supporting plate 8 are components made of the same structure. The lower supporting plate 9 includes a second horizontal plate 91 and a second rotating plate 92. The width of the second horizontal plate 91 is smaller than the width of the first horizontal plate 81, and the width of the second rotating plate 92 is smaller than the width of the first rotating plate 82. The sum of the width of the first rotating plate 82 and the thickness of the first horizontal plate 81 matches the height of the through-slot 62. The width of the second rotating plate 92 matches the spacing between the first horizontal plate 81 and the second horizontal plate 91.

[0041] Specifically, the first horizontal plate 81 and the first rotating plate 82 are connected by a rotating member 83, and the rotating member 83 is used to rotate the first rotating plate 82. The lower supporting plate 9 and the upper supporting plate 8 are components made of the same structure, so the second rotating plate 92 can also rotate, and the second sliding plate 6 will drive the upper supporting plate 8 and the lower supporting plate 9 to move away from the lithium battery block 42 and the insulating plate 41 until one end of the first rotating plate 82 is completely inside the through groove 62. At this time, there is no upper supporting plate 8 and the lower supporting plate 9 within the distance between the two second sliding plates 6, thereby completing the stacking of the insulating plate 41 and the lithium battery block 42. When the two second sliding plates 6 move toward each other, the insulating plate 41 and the lithium battery block 42 are clamped. Previously, the second rotating plate 92 rotated upward, and at this time the end of the second rotating plate 92 contacted the lower side of the first horizontal plate 81, and the rotating member 83 drove the first rotating plate 82 to rotate downward, and the first rotating plate 82 was in a vertical state, and the end of the first rotating plate 82 contacted the bottom of the through groove 62. At this time, it is equivalent to the first rotating plate 82 filling the vacancy of the through groove 62. When the two second sliding plates 6 move to clamp the insulating plate 41 and the lithium battery block 42, the first rotating plate 82 in the vertical state can also clamp the insulating plate 41 or the lithium battery block 42 in contact with it. By fully clamping the insulating plate 41 and the lithium battery block 42, the insulating plate 41 and the lithium battery block 42 are stacked neatly.

[0042] like Figure 6 As shown, a semi-arc groove 85 is opened on the side of the first horizontal plate 81 , and two pulling ropes 851 are installed inside the semi-arc groove 85 . The two pulling ropes 851 are fixedly connected to the corresponding connecting ropes 84 .

[0043] A plurality of driving components 86 are also installed inside the first sliding plate 5. The driving components 86 include a fixed motor 861 fixedly installed inside the first sliding plate 5. One side of the fixed motor 861 is fixedly connected to two winding wheels 862 through an axis. The two winding wheels 862 are movably installed inside the first sliding plate 5. The two winding wheels 862 reel in the corresponding connecting ropes 84. One fixed motor 861 and winding wheel 862 correspond to the upper support plate 8, and one fixed motor 861 and winding wheel 862 correspond to the lower support plate 9.

[0044] Specifically, when the first rotating plate 82 or the second rotating plate 92 needs to rotate, it can be controlled by the corresponding driving component 86 and electrically driven by the fixed motor 861. The fixed motor 861 can drive the two winding wheels 862 to rotate, so that the corresponding connecting rope 84 and the pulling rope 851 are wound or unwound. One end of the pulling rope 851 is fixedly connected to the side of the semi-arc groove 85, and the first rotating plate 82 is rotatably installed on the side of the first horizontal plate 81 through the rotating component 83. Therefore, the pulling rope 851 is wound and unwound, which drives the first rotating plate 82 to rotate. When the first rotating plate 82 rotates to the required angle, the first rotating plate 82 is fixed by the fixed structure to complete the rotation of the first rotating plate 82 or the second rotating plate 92, and a plurality of first rotating plates 82 or second rotating plates 92 can be rotated at the same time.

[0045] Example 2

[0046] like Figure 8-9 As shown, compared with Example 1, another embodiment of the present invention is: the rotating member 83 includes a fixed shaft 831 fixedly connected to the inner wall of the semi-arc groove 85, a plurality of annular grooves 832 are opened inside the fixed shaft 831, a rotating cylinder 833 is movably installed inside the annular groove 832, a connecting strip 834 is fixedly connected to the side of the rotating cylinder 833, one side of the connecting strip 834 is fixedly connected to the first rotating plate 82, a connecting spring 835 is installed inside the rotating cylinder 833, one end of the connecting spring 835 is fixedly connected to the inner wall of the annular groove 832, and the other end is fixedly connected to the inner wall of the rotating cylinder 833.

[0047] Specifically, when the first rotating plate 82 is in a horizontal state and is used to support the insulating plate 41 or the lithium battery block 42, the connecting spring 835 inside the rotating cylinder 833 is in a compressed state. Under the electric drive of the fixed motor 861, the winding wheel 862 rotates to unwind the connecting rope 84. Under the action of the restoring force of the connecting spring 835, the first rotating plate 82 rotates downward. At this time, the fixed shaft 831 is fixed due to its fixed connection with the side wall of the semi-arc groove 85. At this time, the rotating cylinder 833 and the connecting bar 834 will rotate downward together with the first rotating plate 82. Through the same steps and principles, the second rotating plate 92 will rotate upward. When the second rotating plate 92 and the first rotating plate 82 are both in a vertical state, the subsequent clamping steps corresponding to the insulating plate 41 or the lithium battery block 42 are completed.

[0048] like Figure 8 As shown, a sliding block 8331 is fixedly installed on one side of the rotating cylinder 833 , a semi-circular groove 8321 is opened on the inner wall of the annular groove 832 , and the sliding block 8331 is movably installed inside the semi-circular groove 8321 .

[0049] Specifically, during the rotation of the first rotating plate 82, the rotating cylinder 833 and the sliding block 8331 will rotate along with the first rotating plate 82. When the first rotating plate 82 is in a horizontal state for supporting the insulating plate 41 or the lithium battery block 42, the sliding block 8331 will contact the top side wall of the semicircular ring groove 8321. When the first rotating plate 82 is in a vertical state for the clamping step, the sliding block 8331 slides to the bottom of the semicircular ring groove 8321, and the sliding block 8331 contacts the bottom side wall of the semicircular ring groove 8321. The setting of the sliding block 8331 and the semicircular ring groove 8321 limits the first rotating plate 82, ensuring that when the pull rope 851 is wound, the first rotating plate 82 is in a horizontal state, and when the pull rope 851 is unwound, the first rotating plate 82 is in a horizontal state. Under these circumstances, the first rotating plate 82 is in a vertical state, so as to avoid the incorrect rotation angles of the first rotating plate 82 and the second rotating plate 92, which would affect the subsequent assembly steps. Moreover, in the present device, in order to minimize the hard collision between the insulating plate 41 and the lithium battery block 42 caused by stacking, it is necessary to minimize the distance between the insulating plate 41 inserted into the battery assembly station 3 and the lithium battery block 42. Therefore, it is necessary to design thinner upper support plate 8 and lower support plate 9. The present device can rotate the first rotating plate 82 by pulling it through the rope through the setting of the connecting rope 84, the first horizontal plate 81, the rotating member 83 and the first rotating plate 82, so as to avoid setting an electric rotating structure inside the upper support plate 8 or the lower support plate 9 to occupy a large amount of space, which is beneficial to the subsequent use of lithium batteries.

[0050] Working principle: The multi-axis machine 2 clamps multiple lithium battery blocks 42 through the clamping arm 21, and then the glue-coating machine applies glue at the center position above the multiple lithium battery blocks 42. Subsequently, the multiple lithium battery blocks 42 are inserted into the position between the multiple stacked components 7 through the clamping arm 21. The bottom lithium battery block 42 is inserted into the position between the bottom of the mechanism I-plate 4 and the stacked component 7. In the same way, multiple insulating plates 41 are clamped and glued. The clamping arm 21 can insert multiple insulating plates 41 into multiple The spacing between the upper supporting plate 8 and the lower supporting plate 9 is smaller than the spacing between the two upper supporting plates 8 at the same level. The gluing positions of the insulating plate 41 and the lithium battery block 42 are between the two upper supporting plates 8 at the same level. Therefore, when the insulating plate 41 and the lithium battery block 42 are inserted into the battery assembly table 3, the colloid will not be affected. After the lithium battery block 42 and the insulating plate 41 are both inside the battery assembly table 3, they are simultaneously pushed outwards of the mechanism I-shaped plate 4 through the two first sliding plates 5. The stacking members 7 are moved sideways, that is, the distance between the two first sliding plates 5 is increased. The movement of the first sliding plates 5 drives the multiple stacking members 7 to move until the stacking members 7 move to the limit. At this time, there are no multiple stacking members 7 between the two second sliding plates 6. Without the stacking members 7 as partitions, the multiple lithium battery blocks 42 and the insulating plates 41 will be stacked together under the action of gravity. By stacking the multiple insulating plates 41 and the lithium battery blocks 42 at the same time, the processing and assembly efficiency of the lithium battery is accelerated. At this time, the multiple insulating plates 41 and the lithium battery blocks 42 will be initially fixed together by the colloid. Under electric drive, the two second sliding plates 6 move toward each other, narrowing the distance between them, and clamping the multiple insulating plates 41 and the lithium battery blocks 42. The electrically driven rotating plate 61 can be rotated toward the mechanism I-shaped plate 4 under electric drive until it is squeezed with the multiple insulating plates 41 and the lithium battery blocks 42. In this way, the multiple insulating plates 41 and the lithium battery blocks 42 are stacked neatly. After a period of time, the colloid cools, and the automatic processing and assembly of the insulating plates 41 and the lithium battery blocks 42 is completed.

[0051] During the rotation of the first rotating plate 82, the rotating cylinder 833 and the sliding block 8331 will rotate along with the first rotating plate 82. When the first rotating plate 82 is in a horizontal state for carrying the insulating plate 41 or the lithium battery block 42, the sliding block 8331 will contact the top side wall of the semicircular ring groove 8321. When the first rotating plate 82 is in a vertical state for the clamping step, the sliding block 8331 slides to the bottom of the semicircular ring groove 8321, and the sliding block 8331 contacts the bottom side wall of the semicircular ring groove 8321. The setting of the sliding block 8331 and the semicircular ring groove 8321 limits the first rotating plate 82, ensuring that when the pull rope 851 is wound up, the first rotating plate 82 is in a horizontal state, and when the pull rope 851 is unwound , the first rotating plate 82 is in a vertical state, avoiding the incorrect rotation angle of the first rotating plate 82 and the second rotating plate 92, which affects the subsequent assembly steps. Moreover, in this device, in order to minimize the hard collision between the insulating plate 41 and the lithium battery block 42 caused by stacking, it is necessary to minimize the distance between the insulating plate 41 inserted into the battery assembly table 3 and the lithium battery block 42. Therefore, it is necessary to design thinner upper support plate 8 and lower support plate 9. Through the setting of the connecting rope 84, the first horizontal plate 81, the rotating member 83 and the first rotating plate 82, this device can rotate the first rotating plate 82 by pulling the rope, avoiding the setting of an electric rotating structure inside the upper support plate 8 or the lower support plate 9 to occupy a large amount of space, which is beneficial to the subsequent use of lithium batteries.
