Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a battery formation device. Background Technology

[0002] Battery formation is the process of activating the positive and negative electrode materials inside the battery through specific charging and discharging methods, thereby improving the battery's overall performance, including charge / discharge performance, self-discharge, and storage capabilities. Battery formation is the initialization of the battery, activating its active materials; it is essentially an energy conversion process.

[0003] In existing battery formation processes, batteries are typically placed horizontally on a battery formation fixture, with the two tabs of the battery electrically connected to the positive and negative terminals of the fixture, respectively. These fixtures usually have at least 20-40 layers, or even more. Conventional battery formation mechanisms place the batteries vertically for formation. After stacking the battery formation fixtures, the weight of the batteries and the fixtures themselves results in uneven stress on the batteries in the upper fixtures and the lower fixtures. This uneven pressure on batteries at different positions leads to poor formation results and affects the overall performance of the battery.

[0004] Therefore, there is a need to provide a battery formation device that allows the battery formation mechanism to feed batteries when placed vertically, and to rotate the battery formation mechanism to a horizontal position during formation, so as to reduce or avoid the problem of uneven force on the battery. Utility Model Content

[0036] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0039] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0040] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0041] like Figures 1 to 6 As shown, the battery formation equipment includes a support frame 11, a flipping mechanism 12, and a battery formation mechanism 13. The flipping mechanism 12 is connected to the support frame 11, and the battery formation mechanism 13 is connected to the flipping mechanism 12. The flipping mechanism 12 includes a first drive assembly. The battery formation mechanism 13 includes an equipment frame 131, a formation clamping assembly 133, and a connecting assembly. The formation clamping assembly 133 is connected to the equipment frame 131, and the connecting assembly is movably connected to the equipment frame 131. The equipment frame 131 is fixedly connected to the first drive assembly. The connecting assembly is provided with at least one first guide member 1341, and the formation clamping assembly 133 is provided with at least one first guide groove 101. When the formation clamping assembly 133 is installed on the equipment frame 131, each first guide member 1341 is disposed in each first guide groove 101. The first drive assembly drives the battery formation mechanism 13 to flip between the vertical and horizontal directions.

[0042] Specifically, when the battery formation mechanism 13 is placed vertically, the battery is loaded, i.e., the battery is placed inside the formation clamping assembly 133. When the battery formation mechanism 13 is ready, the flipping mechanism 12 flips the battery formation mechanism 13 from the vertical direction to the horizontal direction. At this time, the battery formation mechanism 13 is placed horizontally, with adjacent batteries spaced apart, and the batteries are subjected to uniform force, which can improve the formation effect and the overall stability of the formed battery. Specifically, the support frame 11 is a rectangular frame structure, including a first frame 111 and a second frame 112 fixedly connected. The second frame 112 is set inside the first frame 111. Both the first frame 111 and the second frame 112 are welded with multiple horizontal beams and multiple vertical beams. The first drive assembly of the flipping mechanism 12 is fixedly connected to the second frame 112. The flipping mechanism 12 can drive the battery formation mechanism 13 to flip between the vertical and horizontal directions within the first frame 111. The equipment frame 131 is also a frame structure to achieve visualization and reduce the weight of the battery formation mechanism 13 itself. In this embodiment, the horizontal direction refers to the X direction, and the vertical direction refers to the Y direction.

[0043] The battery formation equipment of this utility model connects the equipment frame 131 of the battery formation mechanism 13 with the flipping mechanism 12. When the formation clamping assembly 133 is installed on the equipment frame 131, the battery formation mechanism 13 is placed vertically. At this time, the battery is fed into the formation clamping assembly 133. Then, the first guide member 1341 of the control connection assembly is set in the first guide groove 101 of the formation clamping assembly 133 for guidance and limitation. The flipping mechanism 12 drives the battery formation mechanism 13 to flip from the vertical direction to the horizontal direction, so that the battery formation mechanism 13 performs formation on the battery when it is placed horizontally. This can reduce or avoid uneven force on the battery, improve the formation effect of the battery and the overall performance of the battery after formation.

[0044] like Figures 1 to 5As shown, the first drive assembly includes a drive member 1211, a first transmission structure 1212, and a second transmission structure 1213. The drive member 1211 is fixedly connected to the support frame 11. The first transmission structure 1212 is connected to the drive end of the drive member 1211. The second transmission structure 1213 is connected to the equipment frame 131. The first transmission structure 1212 and the second transmission structure 1213 mesh. When the drive member 1211 drives the first transmission structure 1212 to rotate the second transmission structure 1213, the battery formation mechanism 13 flips between the vertical and horizontal directions. Specifically, the driving component 1211 includes a first motor 12111, a reducer 12112, and a second rotating shaft 12113. The reducer 12112 is connected to the driving end of the first motor 12111, and the second rotating shaft 12113 is connected to the reducer 12112. The reducer 12112 can drive the second rotating shaft 12113 to rotate. The first transmission structure 1212 is fixedly connected to the second rotating shaft 12113. When the second rotating shaft 12113 rotates, the first transmission structure 1212 drives the second transmission structure 1213 to rotate. The drive unit 1211 also includes a third fixed seat 12116 and a fourth fixed seat 12117. One end of the second rotating shaft 12113 passes through the third fixed seat 12116 and the other end of the second rotating shaft 12113 passes through the fourth fixed seat 12117. The second rotating shaft 12113 can rotate within the third fixed seat 12116 and the fourth fixed seat 12117. The first transmission structure 1212 is disposed between the third fixed seat 12116 and the fourth fixed seat 12117. In addition, there are two first transmission structures 1212, which are spaced apart. The reducer 12112 is disposed between the two first transmission structures 1212. The first transmission structure 1212 is preferably a gear. The second transmission structure 1213 is a sector gear, and the central angle of the second transmission structure 1213 is greater than or equal to 90 degrees, preferably 90°, 120°, 240°, 270° or 360°, etc.; the number of the second transmission structures 1213 is set in correspondence with the number of the first transmission structures 1212.

[0045] like Figure 7As shown, in another preferred embodiment, the driving component 1211 includes a first cylinder 12114, which is fixedly connected to the second frame 112 of the support frame 11. The first transmission structure 1212 includes a rack 12121, a rack base 12122, and a first guide rail 12123. The rack base 12122 is slidably mounted on the first guide rail 12123 and is connected to the telescopic rod of the first cylinder 12114. The rack 12121 is connected to the rack base 12122 and is positioned along the length of the rack base 12122. The rack 12121 meshes with the second transmission structure 1213, which is a sector gear. The telescopic rod of the first cylinder 12114 drives the rack base 12122 and the rack 12121 to move along the length of the first guide rail 12123, thereby driving the second transmission structure 1213 to rotate. This converts the linear motion of the first cylinder 12114 into the rotation of the sector gear. Since the equipment frame 131 is fixedly connected to the second transmission structure 1213, the rotation of the second transmission structure 1213 can be converted into the synchronous rotation of the battery formation mechanism 13. In this embodiment, it is preferable to have one or two transmission structures 1212 and 1213.

[0046] like Figures 1 to 5 As shown, the first drive assembly also includes a first rotating shaft 1214, a first fixed seat 1215, and a second fixed seat 1216. The first fixed seat 1215 and the second fixed seat 1216 are respectively fixedly connected to the support frame 11, that is, the first fixed seat 1215 and the second fixed seat 1216 are respectively fixedly connected to the second frame 112 of the support frame 11. The fixed connection method is preferably welding, which can improve the stability and reliability of the connection. The first rotating shaft 1214 is set through the first fixed seat 1215 and the second fixed seat 1216. The equipment frame 131 is fixedly connected to the first rotating shaft 1214. When the equipment frame 131 rotates, the first rotating shaft 1214 can rotate relative to the first fixed seat 1215 and the second fixed seat 1216 to reduce the friction force when the equipment frame 131 rotates.

[0047] like Figure 5 , Figure 6 and Figure 9As shown, the connecting assembly also includes a reciprocating drive mechanism 1342, which is fixedly connected to the device frame 131. The first guide member 1341 is connected to the reciprocating drive mechanism 1342, and the reciprocating drive mechanism 1342 can drive the first guide member 1341 to move toward or away from the first guide groove 101. Specifically, the reciprocating drive mechanism 1342 includes a second cylinder 13421, a second guide rail 13422, and a second sliding block 13423. The second cylinder 13421 and the second guide rail 13422 are respectively fixedly connected to the equipment frame 131. The second sliding block 13423 is slidably disposed on the second guide rail 13422 and is fixedly connected to the drive end of the second cylinder 13421. The first guide member 1341 is fixedly connected to the second sliding block 13423. When the second cylinder 13421 drives the second sliding block 13423 to move along the length direction of the second guide rail 13422, the second sliding block 13423 drives the first guide member 1341 to move towards or away from the first guide groove 101. That is, the second cylinder 13421 drives the first guide member 1341 to be disposed in the first guide groove 101, or the second cylinder 13421 drives the first guide member 1341 to disengage from the first guide groove 101. The first guide member 1341 is arranged along the length direction of the formation clamping assembly 133. The first guide member 1341 is preferably a strip-shaped cylindrical structure or a strip-shaped rectangular structure, but is not limited thereto.

[0048] like Figure 10 As shown, in another preferred embodiment, the reciprocating drive mechanism 1342 includes a second motor 13424, a second lead screw 13425, and a connecting block 13426. The second motor 13424 is fixedly connected to the equipment frame 131. The second lead screw 13425 is connected to the drive end of the second motor 13424. The second lead screw 13425 passes through the connecting block 13426, and the connecting block 13426 is threadedly connected to the second lead screw 13425. The first guide member 1341 is fixedly connected to the connecting block 13426. When the second motor 13424 drives the second lead screw 13425 to rotate, since the connecting block 13426 is threadedly connected to the second lead screw 13425, the rotation of the second lead screw 13425 can be converted into the linear motion of the connecting block 13426, causing the first guide member 1341 to move along the length direction of the second lead screw 13425.

[0049] like Figure 3 , Figure 4 and Figure 15As shown, the formation clamping assembly 133 includes a first end 13c and a second end 13d, the first end 13c and the second end 13d are disposed opposite to each other, a first guide groove 101 is disposed at the first end 13c, there are two first guide grooves 101, the two first guide grooves 101 are spaced apart along the width direction of the first end 13c, the electrode terminal 13311 of the formation clamping assembly 133 is located between the two first guide grooves 101; there are two first guide members 1341.

[0050] In another preferred embodiment, a first guide groove 101 is provided at the second end 13d, and two first guide grooves 101 are provided, and two second guide members 1341 are provided.

[0051] In another preferred embodiment, both the first end 13c and the second end 13d are provided with first guide grooves 101. The first end 13c has two first guide grooves 101, and the second end 13d has two first guide grooves 101. There are four first guide members 1341 and two reciprocating drive mechanisms 1342. One reciprocating drive mechanism 1342 is correspondingly arranged with the first end 13c of the formation clamping assembly 133, and the other reciprocating drive mechanism 1342 is correspondingly arranged with the second end 13d of the formation clamping assembly 133. The two first guide members 1341 on the same side are connected to the second sliding block 13423 or the connecting block 13426. This makes it easier for the formation clamping assembly 133 to adapt to different types of battery formation equipment. In addition, four reciprocating drive mechanisms 1342 can be provided, with two reciprocating drive mechanisms 1342 fixedly connected to the top of the equipment frame (the top refers to the area above the clamping component 133 when the equipment frame 131 is set in a vertical direction), and two reciprocating drive mechanisms 1342 fixedly connected to the bottom of the equipment frame (the bottom refers to the area below the clamping component 133 when the equipment frame 131 is set in a vertical direction).

[0052] like Figure 4 , Figure 15 and Figure 16As shown, a first pulley 13a and a second pulley 13b are provided in the first guide groove 101. The first pulley 13a and the second pulley 13b are arranged opposite to each other. When the first guide member 1341 is arranged in the first guide groove 101, the first pulley 13a and the second pulley 13b abut against or contact the first guide member 1341. Specifically, the axis of the first pulley 13a and the axis of the second pulley 13b are both perpendicular to the axis of the first guide member 1341. The formation clamping assembly 133 includes a plurality of stacked cell formation clamps 1331, with adjacent cell formation clamps 1331 spaced apart. Each cell formation clamp 1331 is provided with a first guide groove 101. The first guide groove 101 includes a first groove segment 1011, a second groove segment 1012 and a third groove segment 1013 connected in sequence. The second groove segment 1012 is located between the first groove segment 1011 and the third groove segment 1013. The first pulley 13a is connected in the first groove segment 1011 and the second pulley 13b is connected in the third groove segment 1013. At least a portion of the first pulley 13a and at least a portion of the second pulley 13b protrude from the groove wall of the second groove segment 1012. Multiple cell formation fixtures 1331 are stacked and placed in the formation clamping assembly 133 at once, reducing repetitive labor for workers. A first pulley 13a is fixedly connected to the wall of the first groove segment 1011 by screws, and a second pulley 13b is fixedly connected to the wall of the third groove segment 1013 by screws. The depth of the first groove segment 1011 is less than the depth of the second groove segment 1012, and the depth of the third groove segment 1013 is less than the depth of the second groove segment 1012. The first pulley 13a and the second pulley 13b are installed on the same horizontal plane. The battery formation mechanism 13 requires a certain amount of pressure when forming the battery. When the battery formation mechanism 13 is flipped from a vertical direction to a horizontal direction, pressure needs to be applied to each cell formation fixture 1331 of the battery formation mechanism 13. The sliding of the first pulley 13a and the second pulley 13b on the first guide member 1341 reduces friction and ensures that the force on each cell formation fixture 1331 is uniform. It is understandable that when the battery formation mechanism 13 is flipped from the vertical direction to the horizontal direction, if the first pulley 13a is located above the first guide member 1341, the first pulley 13a will be attached to the first guide member 1341.

[0053] like Figure 12 , Figure 14 as well as Figure 17 As shown, the battery formation equipment also includes a contact switching mechanism 132, which is movably connected to the equipment frame 131. The formation clamping assembly 133 is provided with electrode terminals 13311, which are elastic. When the formation clamping assembly 133 is installed in the equipment frame 131, the contact switching mechanism 132 is in elastic contact with and electrically connected to the electrode terminals 13311.

[0054] like Figure 11 , Figure 12 and Figure 14 As shown, the contact switching mechanism 132 includes at least one set of first drivers 1321 and contact assemblies 1322. The first drivers 1321 are fixedly connected to the device frame 131, and the contact assemblies 1322 are connected to the driving end of the first drivers 1321. The contact assemblies 1322 are correspondingly arranged with the electrode terminals 13311. The first drivers 1321 can drive the contact assemblies 1322 to move towards or away from the electrode terminals 13311. Since the contact assembly 1322 is long, it is preferable to have two sets of first drivers 1321, which are spaced apart along the length of the contact assembly 1322 to increase the stability of the contact assembly 1322 during movement.

[0055] like Figure 11 , Figure 12 and Figure 14 As shown, the contact assembly 1322 includes a first connecting plate 13223, a contact copper busbar 13221, and multiple leads 13222. The first connecting plate 13223 is preferably a rectangular plate. The first connecting plate 13223 is fixedly connected to the driving end of the first driver 1321. The contact copper busbar 13221 is fixedly connected to the first connecting plate 13223. The first connecting plate 13223 is used to support the contact copper busbar 13221. The first driver 1321 can drive the first connecting plate 13223 and the contact copper busbar 13221 to move towards or away from the electrode terminal 13311. The contact copper busbar 13221 is provided with multiple parallel electrode slots 103. Each electrode slot 103 extends along the length of the contact copper busbar 13221. Each lead 13222 is respectively disposed in each electrode slot 103. Each electrode slot 103 is used for electrical connection with the electrode terminal 13311.

[0056] Preferably, the first driver 1321 is a driving cylinder, the cylinder body of which is fixedly connected to the equipment frame 131. The first connecting plate 13223 of the contact assembly 1322 is fixedly connected to the telescopic end of the driving cylinder. When the telescopic end of the driving cylinder extends or retracts, it can drive the first connecting plate 13223 and the contact copper busbar 13221 to move along the axial direction of the driving cylinder, thereby realizing the electrical connection between the contact copper busbar 13221 and the electrode terminal 13311 of the formation clamping assembly 133.

[0057] like Figures 15 to 17As shown, each cell formation fixture 1331 also includes a formation tray 13312. Electrode terminals 13311 are electrically connected to the formation tray 13312. Each electrode terminal 13311 includes six pins 13311a, each pin 13311a having an elastic structure. Specifically, the formation tray 13312 includes a first connecting surface 13312a, which is located at one end of the formation tray 13312 near the contact copper busbar 13221. The first connecting surface 13312a is recessed in the direction away from the contact copper busbar 13221 to form six pin slots 105. Adjacent pin slots 105 are spaced apart. Each pin 13311a is respectively located within its respective pin slot 105 and electrically connected to the formation tray 13312. At least part of the structure of 13311a extends beyond the first connecting surface 13312a to facilitate elastic contact and electrical connection between each pin 13311a and each pin slot 105. Each pin 13311a is preferably a spring sheet. When the pin 13311a contacts the electrode slot 103, the pin 13311a is compressed under the pressure of the contact copper busbar 13221 and achieves electrical connection with each lead 13222. When the contact copper busbar 13221 is removed, each pin 13311a restores its elastic deformation.

[0058] like Figure 17 As shown, the six pins 13311a are the charging positive terminal, charging negative terminal, heating positive terminal, heating negative terminal, and two communication terminals; the pin slots 105 also have six pins, which are respectively set to correspond to the six pins 13311a.

[0059] Preferably, after the electrode terminals 13311 of each cell formation fixture 1331 are stacked, the pins 13311a with the same function are located in the same column. For example, when the battery formation mechanism 13 is placed vertically, the charging positive terminals of two adjacent cell formation fixtures 1331 in the vertical direction are located in the same column.

[0060] like Figure 8 and Figure 9 As shown, the contact switching mechanism 132 also includes a limiting seat 1324, which is fixedly connected to the equipment frame 131. The fixing connection method is preferably bolt connection or welding. Each lead wire 13222 is connected to the limiting seat 1324. The limiting seat 1324 is used to fix and limit each lead wire 13222 to prevent the lead wires 13222 from getting tangled during the movement of the contact assembly 1322.

[0061] Please continue to refer to Figure 8 and Figure 9The contact switching mechanism 132 also includes a second guide 1325, which includes a base 13251 and a second guide rod 13252. The base 13251 is fixedly connected to the equipment frame 131. One end of the second guide rod 13252 is fixedly connected to the contact assembly 1322, and the other end of the second guide rod 13252 passes through the base 13251. When the contact assembly 1322 moves, the second guide rod 13252 can move within the base 13251 to guide the contact assembly 1322 and prevent the contact assembly 1322 from shifting during movement. Specifically, the base 13251 is provided with a first through hole, and the equipment frame 131 is provided with a second through hole 107. The first through hole and the second through hole 107 are correspondingly arranged. The second guide rod 13252 includes a guide part 13252a and a limiting part 13252b that are fixedly connected. The guide part 13252a is provided through the first through hole and the second through hole 107. The outer diameter of the limiting part 13252b is larger than the outer diameter of the guide part 13252a, and the outer diameter of the limiting part 13252b is larger than the inner diameter of the first through hole. When the contact assembly 1322 extends out and cooperates with the electrode terminal 13311, the limiting part 13252b abuts against the base 13251 to limit the second guide rod 13252 and prevent the second guide rod 13252 from falling off. Two second guide members 1325 are provided, and the two second guide members 1325 are arranged along the length direction of the first connecting plate 13223 to increase the stability and reliability of the contact copper busbar 13221 when it moves.

[0062] Preferably, the battery formation equipment further includes a control system, a first sensor, and a second sensor. The first sensor and the second sensor are electrically connected to the control system. The first drive assembly, the formation clamping assembly 133, the connecting assembly, and the contact switching mechanism 132 are all electrically connected to the control system. The second sensor is used to sense whether the first guide member 1341 is disposed in the first guide groove 101. When the second sensor senses that the first guide member 1341 is disposed in the first guide groove 101, the second sensor feeds back an electrical signal to the control system. The control system drives the first drive assembly to rotate the equipment frame 131 and the battery formation mechanism 13 from the vertical direction to the horizontal direction. When the first sensor senses that the battery formation mechanism 13 has rotated to the horizontal direction, it feeds back a signal to the control system. The control system controls the contact switching mechanism 132 to move toward the direction close to the battery formation mechanism 13 and to electrically connect with the electrode terminals 13311 of the battery formation mechanism 13. The control system can control the formation clamping assembly 133 to perform the battery formation operation.
