Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery assembly, and in particular to a lithium battery intelligent assembly device and method. Background Art

[0002] Lithium battery is a type of rechargeable battery that uses lithium ions as charge carriers. During the use of lithium batteries, the capacity or voltage of a single lithium battery usually does not meet the use requirements, so multiple single lithium batteries need to be combined into a battery system through series, parallel or series-parallel connection. The assembly of this battery system is simply referred to as lithium battery assembly.

[0003] The existing method of assembling lithium battery packs usually uses a fixing fixture on a workbench to clamp all the battery blocks by clamping at both ends. Then the operator uses tape to tie the upper and lower ends of all the battery blocks as a whole, and then installs the controller, resistance balancing board and connecting plate, and connects the wiring of the resistance balancing board to the connecting plate. Then, the wiring of the resistance balancing board and the wiring of the controller are connected by welding, and the resistance balancing board is stably connected to the top of the battery block. Then, the outer frame plate is installed. After the outer frame plate is installed, the operator puts the plastic rubber sleeve on the outer frame plate and completes the assembly of the lithium battery pack.

[0004] Although the above-mentioned assembly method is capable of quickly assembling lithium battery packs, the operator needs to continuously flip the battery blocks when tying the battery blocks with tape. The above-mentioned fixing fixture is cumbersome to operate when flipping more battery blocks, which makes it difficult to accurately tie the tape, and thus makes the overall volume have a large error after all the battery blocks are tied, affecting the overall size of the lithium battery pack; in addition, due to the lack of stability of the resistance balancing board wiring and the controller wiring when welding the resistance balancing board wiring and the connecting piece, the two are in a loose state during the welding process, which makes it easy to have cold welding, affecting the normal use of the assembled lithium battery pack.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0033] See also Figure 1-Figure 2 A lithium battery intelligent assembly device includes a storage plate 1, a vertical plate 11 is fixed symmetrically on the top of the storage plate 1, and height adjustment mechanisms 2 are symmetrically arranged on the two vertical plates 11.

[0034] The present invention clamps the battery blocks for assembling into a lithium battery pack through the cooperation of the left clamping mechanism 3 and the right clamping mechanism 4, and at the same time, the battery blocks after clamping can be moved upward through the height adjustment mechanism 2, so that it is convenient for the operator to tie all the battery blocks with tape, and the clamping range is adjusted through the length adjustment mechanism 5, so that it can quickly adapt to different numbers of battery blocks, and then different numbers of battery blocks can be assembled.

[0035] Specifically, firstly, the battery block for assembling the lithium battery pack is placed on the top of the storage plate 1, and the positive and negative electrodes of the two adjacent battery blocks are close to each other. Then, the clamping range of the left clamping mechanism 3 and the right clamping mechanism 4 is adjusted by the length adjustment mechanism 5 according to the number of battery blocks, so that the left clamping mechanism 3 and the right clamping mechanism 4 can surround all the battery blocks. Then, the two cylinders 22 are controlled to synchronously drive the left clamping mechanism 3 and the right clamping mechanism 4 to clamp and limit all the battery blocks. Then, the height adjustment mechanism 2 is used to cooperate with the left clamping mechanism 3 and the right clamping mechanism 4 to clamp and limit all the battery blocks. The mechanism 4 drives all the battery blocks to move away from the storage plate 1, and all the battery blocks are tied up with tape. After the tying is completed, the controller and the resistance balancing board are installed and welded, and then the outer frame plates at the front and rear positions and the upper and lower positions are installed by the left clamping mechanism 3 and the right clamping mechanism 4. After the installation is completed, they are connected by means of an adhesive. After the connection is completed, the clamping effect of the left clamping mechanism 3 and the right clamping mechanism 4 on the battery blocks is released, and the outer frame plates on the left and right sides are installed. After the installation is completed, the lithium battery pack is stabilized as a whole by an external plastic rubber sleeve.

[0036] See also Figure 1 , Figure 2 , Figure 3 and Figure 7The left clamping mechanism 3 includes a convex frame 31 fixed to the pushing end of the left cylinder 22, and a fixing member 32 for positioning the controller is arranged at the left end of the convex frame 31; the right clamping mechanism 4 includes a U-shaped frame 41 fixed to the pushing end of the right cylinder 22, and a plurality of groups of stabilizing members 42 are symmetrically arranged on the U-shaped frame 41 and the convex frame 31, and each group of stabilizing members 42 is composed of stabilizing members 42 symmetrically arranged front and back.

[0037] The height adjustment mechanism 2 includes a vertical groove 21 opened on the vertical plate 11, and a sliding column 211 is slidably connected in the vertical groove 21. The opposite ends of the two sliding columns 211 are connected to the cylinder 22, and a positioning component 23 is commonly provided between the end of the sliding column 211 away from the cylinder 22 and the vertical plate 11; the positioning component 23 includes a limit plate 231 fixed to the end of the sliding column 211 away from the cylinder 22, and the limit plate 231 is symmetrically provided with positioning holes 232 front and back, and a plurality of vertically arranged coordination holes 233 are linearly and evenly arranged on the vertical plate 11 and located at the rear side of the vertical groove 21, and a positioning pin is commonly connected between the positioning hole 232 and the coordination hole 233 at the corresponding position, and a fixing rod 234 is fixed to the side of the limit plate 231 away from the cylinder 22.

[0038] Through the left clamping mechanism 3 and the right clamping mechanism 4, all battery blocks can be positioned by pressing the battery blocks at the left and right ends. At the same time, the resistance balancing plate, connecting plate and controller can be assisted in positioning through the fixing component 32 and the stabilizing component 42, and the installation of the three can be facilitated. The height of the left clamping mechanism 3 and the right clamping mechanism 4 can be adjusted by the height adjustment mechanism 2, which can facilitate the operator to tie all the clamped battery blocks with tape.

[0039] Specifically, the battery blocks are first placed on the top of the storage plate 1, and the positive and negative poles of the two adjacent battery blocks are close to each other. Then, the two cylinders 22 push the convex frame 31 and the U-shaped frame 41 to clamp the battery blocks. After all the battery blocks are clamped, the positioning function of the positioning pins is released. Then, the fixed rods 234 on the left and right sides are lifted at the same time to push the sliding column 211, the cylinder 22 and all the battery blocks upward, so that the battery blocks move upward to a certain height. After the movement is completed, the positioning pins are inserted into the positioning holes 232 and the matching holes 233 again, and the operator can tape all the battery blocks at the upper and lower positions, so that all the battery blocks form a whole.

[0040] See also Figure 3-Figure 4The length adjustment mechanism 5 includes a limiting groove 51 arranged at the opposite ends of the U-shaped frame 41 and the convex frame 31, and a moving plate 511 is slidably connected in each limiting groove 51, and a position adjustment member 52 is arranged between the moving plate 511 and the U-shaped frame 41 or the convex frame 31, and the moving plate 511 is also connected to the stabilizing member 42 through the avoidance member 53; the position adjustment member 52 includes a synchronous plate 521 fixed on the moving plate 511 symmetrically up and down, and the synchronous plate 521 is located on the side of the moving plate 511 away from the moving plate 511 corresponding to the front and rear positions, and the positions corresponding to the synchronous plates 521 on the convex frame 31 and the U-shaped frame 41 are provided with locking holes 522, and the locking holes 522 and the synchronous plates 521 at the corresponding positions are commonly connected with limiting pins.

[0041] The length adjustment mechanism 5 is used to adjust the lengths of the U-shaped frame 41 and the convex frame 31, so that the U-shaped frame 41 and the convex frame 31 can clamp different numbers of battery blocks, while ensuring the clamping stability of the U-shaped frame 41 and the convex frame 31 during the clamping process, and the number of stabilizing members 42 can be adjusted according to the number of battery blocks through the avoidance member 53.

[0042] Continue reading Figure 3-Figure 4 The fixing member 32 includes an avoidance groove symmetrically opened at the left end of the convex frame 31, the two avoidance grooves are located at the raised part of the convex frame 31, each avoidance groove is slidably connected with a clamping plate 321, and rubber pads are arranged on the opposite sides of the two clamping plates 321, a two-way threaded rod 322 is rotatably installed at the left end of the convex frame 31, the two-way threaded rod 322 is threadedly connected to each clamping plate 321, a crank is fixed at the front end of the two-way threaded rod 322, and a receiving structure for supporting the bottom of the controller is arranged at the left end of the bottom of the convex frame 31; the receiving structure includes a lower extension column 323 fixed at the left end of the bottom of the convex frame 31, a receiving plate 325 is connected to the lower extension column 323 through a vertical sliding sleeve 324, a square plate 326 is fixed to the bottom of the lower extension column 323, and a vertical spring is connected between the square plate 326 and the receiving plate 325.

[0043] The clamping plate 321 with rubber pads in the fixing member 32 can clamp and position the controller, and the receiving plate 325 can quickly limit the height of the controller. At the same time, the controller can be clamped and protected by the rubber pads.

[0044] Specifically, after the tape binding of all the battery blocks is completed, the controller is placed at the left end of the convex frame 31 and between the two clamping plates 321. Then, the height of the controller is adjusted by pressing the controller downward and pressing the controller against the receiving plate 325. After the position of the controller is determined, the operator manually shakes the handle and rotates the bidirectional threaded rod 322. As the bidirectional threaded rod 322 rotates, the two clamping plates 321 will cooperate with the rubber pads to position and clamp the controller. After the controller is positioned, an insulating plate is inserted between the controller and the battery block on the left. Then, the controller, the insulating plate used to separate the controller and the battery block, and the battery block are connected together through an adhesive. After the connection is completed, a connecting plate can be put between the positive and negative poles of adjacent battery blocks, and a resistance balancing plate and wiring of the resistance balancing plate can be installed between the positive and negative poles of each battery block.

[0045] See also Figure 3 , Figure 4 , Figure 5 and Figure 8 The avoidance component 53 includes a limiting sleeve 531 fixed on the side of the moving plate 511 corresponding to the front and rear positions away from the moving plate 511, and an oblique slide plate 532 is slidably connected in the limiting sleeve 531. The top of the oblique slide plate 532 is connected to the stabilizing component 42 through a connecting plate. An oblique hole is formed on the oblique slide plate 532, and a circular hole is formed on the limiting sleeve 531. The circular hole and the oblique hole at the corresponding position are connected with an avoidance nail.

[0046] The stabilizing member 42 includes an elastic telescopic rod fixed on the top of the convex frame 31 or the U-shaped frame 41, and a rotating pressure plate 421 is rotatably installed on the telescopic end of the elastic telescopic rod. Positioning plates 422 are symmetrically fixed to the top of the elastic telescopic rod. Each positioning plate 422 is provided with a circular hole. An L-shaped mounting plate 423 is fixed on the top of the rotating pressure plate 421. A mounting hole is provided on the horizontal section of the L-shaped mounting plate 423. A fixing pin is connected between the mounting hole and the circular hole at the corresponding position, and the fixing pin slides through the rotating pressure plate 421.

[0047] The stabilizing member 42 is used to stabilize the resistance balancing plate, the wiring and the connecting piece of the resistance balancing plate, so as to facilitate the subsequent welding of the wiring of the controller and the wiring of the resistance balancing plate, and the stabilizing member 42 located on the movable plate 511 is avoided by the avoidance member 53, so that when the length adjustment mechanism 5 adjusts the length of the convex frame 31 or the U-shaped frame 41 according to the number of battery blocks, it can also press the wiring and the connecting piece of the resistance balancing plate at the position of the added battery block.

[0048] Specifically, when the resistance balancing plate and the wiring of the resistance balancing plate are installed, the rotating pressure plate 421 is located outside the area formed by the convex frame 31 and the U-shaped frame 41. Then the operator pulls the rotating pressure plate 421 upward until the rotating pressure plate 421 is above the connecting piece and the resistance balancing plate. Then the fixing pin is removed and the rotation state of the rotating pressure plate 421 is adjusted, so that the rotating pressure plate 421 is rotated to the inside of the area formed by the convex frame 31 and the U-shaped frame 41. After the rotation is completed, the rotation angle of the rotating pressure plate 421 can be fixed by the fixing pin. At this time, the rotating pressure plate 421 will be pressed against the wiring and the top of the connecting piece of the resistance balancing plate due to the action of the elastic telescopic rod, thereby stabilizing the wiring and the connecting piece of the resistance balancing plate. After stabilization is completed, the operator can weld the wiring of the resistance balancing plate and the wiring between the controller.

[0049] See also Figure 3 , Figure 5 , Figure 6 and Fig. 9 Two groups of pressing structures are symmetrically arranged on the U-shaped frame 31, each group of pressing structures is composed of pressing structures symmetrically arranged up and down, the positions of the pressing structures and the stabilizing member 42 are staggered with each other, the pressing structure includes an elastic telescopic rod fixed on the top of the U-shaped frame 31, and a lower pressure plate 311 is rotatably installed on the top of the elastic telescopic rod, and the vertical section and horizontal section of the U-shaped frame 41 are both provided with pressing structures.

[0050] An internal pressure structure is provided on the convex frame 31, the U-shaped frame 41 and the movable plate 511. The internal pressure structure includes square grooves opened on opposite sides of two corresponding movable plates 511 at the front and rear. An internal pressure block 540 is slidably connected in each square groove. A plurality of internal springs are connected between the internal pressure block 540 and the square groove. A positioning slope is provided on the top of the internal pressure block 540.

[0051] The pressing structure and the internal pressure structure are used to install the outer frame plates at the front and rear positions and the upper and lower positions. The positions of the outer frame plates at the upper and lower positions are quickly fixed by the lower pressure plate 311, so as to facilitate fixing the positions of all the outer frame plates and connecting the outer frame plates and the battery blocks. The internal pressure block 540 can avoid the installation of the outer frame plates when the outer frame plates at the front and rear positions are installed, and at the same time make the outer frame plates close to the battery blocks, so that the size accuracy of the battery blocks and the outer frame plates is higher after the connection is completed.

[0052] Specifically, when the wiring of the resistance balancing board and the wiring between the controller are welded and connected, the stability of the stabilizing member 42 is released to the left and right. At this time, the rotating pressure plate 421 will be located outside the area formed by the convex frame 31 and the U-shaped frame 41, and then the outer frame plate is inserted into the position of the inner pressure block 540, and the outer frame plate will press the inner pressure block 540 into the square groove, so that the outer frame plate is inserted between the inner pressure block 540 and the battery block, and then the upper and lower outer frame plates are pressed against the upper and lower positions of the outer frame plates at the front and rear positions, and the elastic telescopic rod is extended by pulling up the lower pressure plate 311 until the lower pressure plate 311 can press against the upper and lower positions after rotation. The side of the outer frame plate is placed, and then the lower pressing plate 311 is rotated, so that the outer frame plates at the front and rear positions are positioned by the lower pressing plates 311 at the upper and lower positions, and the outer frame plates at the upper and lower positions are fixed by three groups of lower pressing plates 311. After the outer frame plates are fixed, the operator connects the outer frame plates at the front and rear upper and lower positions and the battery blocks through insulating double-sided tape. After the connection between the outer frame plates and the battery blocks is completed, the convex frame 31 and the U-shaped frame 41 can be controlled to release the clamping effect on the battery blocks, and the outer frame plates at the left and right positions can be installed. After the installation is completed, the lithium battery pack is stabilized as a whole with an external plastic rubber sleeve.

[0053] In addition, the present invention also provides a lithium battery intelligent assembly method, and the specific assembly method steps are as follows: S1, first place multiple battery blocks for installing the lithium battery pack on the top of the storage plate 1 and place them between the convex frame 31 and the U-shaped frame 41, and then adjust the position of the movable plate 511 through the position adjustment component 52 according to the number of battery blocks.

[0054] S2. After the position adjustment of the movable plate 511 is completed, the two cylinders 22 are controlled to synchronously push the convex frame 31 and the U-shaped frame 41 to complete the combination of all battery blocks. The positive and negative poles on the assembled battery blocks are in a state of being close to each other. Then, the positioning member 23 is used to adjust the height of all battery blocks and the fixing tape is wound.

[0055] S3. After all the battery blocks are combined with tape, an insulating plate is then pasted on the left end of the leftmost battery block, and the controller is installed through the fixing member 32. At the same time, connecting plates are installed on the positive and negative poles of the two adjacent battery blocks, and the resistance balancing plate and the wiring of the resistance balancing plate are installed on the connecting plates. At the same time, the wiring of all connecting plates and the resistance balancing plate is stabilized by a stabilizing member 42, and then the circuits of the controller and the wiring of all the resistance balancing plates are welded.

[0056] S4. After the controller circuits and all resistance balancing board connections are welded, outer frame plates are placed on the outside of all battery blocks at the front, back, top and bottom positions, and connected with adhesive. The two cylinders 22 are then controlled to synchronously pull the convex frame 31 and the U-shaped frame 41 away from the battery blocks. The battery blocks, outer frame plates, resistance balancing boards and controllers are then removed, and the outer frame plates on the left and right sides are installed.
