[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable, while rechargeable lithium metal batteries are superior to lithium ion batteries in terms of safety, specific capacity, and self-discharge rate. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements.

[0003] For example, in the prior art, a multi-angle flipping device for anti-drop lithium battery assembly with publication number CN114744268A clamps the lithium battery by a clamping assembly, and combines the rotation and deflection of the flip frame to achieve a flexible adjustment effect of flipping the lithium battery at any angle; however, the above patent content can achieve the convenience of flipping detection after lithium battery assembly by clamping on both sides, but it is difficult to achieve a stable clamping effect during the horizontal and vertical arrangement and assembly of multiple lithium battery cells, which is not conducive to the flipping processing effect during the assembly process;

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1-Figure 7 As shown, in the prior art, it is difficult to stably clamp multiple lithium battery cells when assembling them in a horizontal and vertical arrangement, which is not conducive to assembly and flipping processing. The following solution can be used to solve the problem;

[0035] The lithium battery assembly multi-angle flipping device with an anti-dropping mechanism in this embodiment includes a fixed platform 1, a fixed partition 11 is welded inside the fixed platform 1, a flip assembly 2 is arranged on the fixed platform 1, and the flip assembly 2 includes a flip frame 21, and the flip frame 21 is located above the top of the fixed platform 1, which is convenient for placing and removing the lithium battery before and after assembly. Support plates 22 and vertical plates 23 are welded on both sides of the top of the fixed platform 1. The support plate 22 is located in the middle of one side of the fixed platform 1, and is used to cooperate with the support shaft to support the middle of the flip frame 21. The vertical plate 23 is located at the corner on the same side of the top of the fixed platform 1 and the support plate 22, and is used to combine the lever 24 and the support shaft to realize the lifting or pressing operation of the flip frame 21;

[0036] A support shaft that contacts the corresponding support plate 22 is fixedly connected to the flip frame 21, and a lever 24 that is hinged to the corresponding vertical plate 23 is rotatably connected to the support shaft. Auxiliary rods 25 are hinged between the two sides of the flip frame 21 and the fixed platform 1. The hinge point between the auxiliary rod 25 and the fixed platform 1 is located directly below the support plate 22. The flip frame 21 is lifted by pressing down the free end of the lever 24, and during the lifting process, the flip frame 21 is caused to flip 90° with the help of the auxiliary rod 25.

[0037] The free end of the rear lifting lever 24 presses down on the flip frame 21, and in combination with the auxiliary rod 25, the flip frame 21 is prompted to continue flipping 90°. Through a lifting movement of the free end of the lever 24, the 180° flipping process of the flip frame 21 is completed, and the height of the rising or falling free end of the lever 24 is controlled, so that the flipping angle of the flip frame 21 can be fixed, and assembly and detection processes at different angles can be realized.

[0038] A receiving plate 3 is provided below the flip frame 21, which is used to support the multiple lithium battery cells before they are clamped in the flip frame 21, so as to ensure the smooth multi-faceted clamping and fixing. At the same time, the upper part of the lithium battery cell is placed on the upper outer side of the flip frame 21, so as to facilitate the tape wrapping of the multiple lithium battery cells after clamping, thereby further improving the convenience in the assembly process;

[0039] The flip frame 21 is provided with a clamping assembly 4 matched therewith, and the clamping assembly 4 includes a clamping plate 1 41 and a clamping plate 2 42 which are slidably connected inside the flip frame 21 and are distributed in a cross shape. The clamping plate 1 41 is provided with a clearance groove for the clamping plate 2 42 to pass through and slide, and one side of the clamping plate 1 41 and the clamping plate 2 42 are fixed with anti-slip pads to further increase the anti-drop effect during the clamping and flipping process;

[0040] One side of the clamping plate 1 41 and the clamping plate 2 42 are both fixedly connected with two groups of piston rods 43, the free ends of the piston rods 43 are fixedly connected with piston blocks 1 44, and the flip frame 21 is fixedly connected with a hydraulic cylinder barrel 45 that is slidably connected with the corresponding piston blocks 1 44, and the two sides of the clamping plate 1 41 are symmetrically fixedly connected with limited slides, and the flip frame 21 is provided with a sliding groove 1 that is slidably connected with the limited slide, which is used for the clamping plate 1 41 to slide horizontally in a stable manner, and the two sides of the clamping plate 2 42 are symmetrically fixedly connected with the limited slide, and the inner side wall of the flip frame 21 is provided with a sliding groove 2 that is slidably connected with the limited slide, which is used for the clamping plate 2 42 to slide horizontally in a stable manner;

[0041] To eliminate the problem of uneven pressure of hydraulic oil entering multiple groups of hydraulic cylinder barrels 45, which causes the sliding jam of clamp plate 1 41 and clamp plate 2 42, the piston rod 43 on clamp plate 1 41 is fixedly connected to the limiting slide plate, and its corresponding hydraulic cylinder barrel 45 is installed on the outside of the flip frame 21, and the corresponding hydraulic cylinder barrel 45 on clamp plate 2 42 is installed on the inside of the flip frame 21, so as to avoid the problem that one of the hydraulic cylinder barrels 45 on clamp plate 1 41 or clamp plate 2 42 cannot be installed.

[0042] A movable plate 12 is slidably connected to the fixed partition 11, and a lifting plate 13 is fixedly connected to the bottom of the movable plate 12. An electric push rod 14 is symmetrically fixedly connected between the lifting plate 13 and the fixed partition 11. The movable plate 12 driven by the electric push rod 14 cooperates with the clamping assembly 4, the receiving plate 3 and the flipping assembly 2 in sequence to achieve a multi-functional driving effect of a single power source.

[0043] A support rod 26 that contacts the bottom of the flip frame 21 is fixedly connected between the vertical plates 23, and is used to cooperate with the auxiliary rod 25 and the support shaft to provide multi-point support for the flip frame 21. A connecting rod 27 is fixedly connected between the ends of the lever 24. A movable block 15 is slidably connected to the fixed platform 1, and a pull rod 28 is hinged between the movable block 15 and the connecting rod 27. A spring 16 is fixedly connected between the bottom of the movable block 15 and the fixed platform 1, and a push plate 17 is welded to one side of the movable block 15.

[0044] After the electric push rod 14 drives the lifting plate 13 to descend and contact with the pushing plate 17, it drives the movable block 15 to compress the spring 16 to move, and drives the two groups of levers 24 to lift the flip frame 21 through the pull rod 28 and the connecting rod 27, and combines with the auxiliary rod 25 to cause the flip frame 21 to flip 90°. When the lifting plate 13 rises, the movable block 15 resets and moves upward under the compression elasticity of the spring 16, and again drives the two groups of levers 24 to press down the flip frame 21 through the pull rod 28 and the connecting rod 27, and combines with the auxiliary rod 25 to cause the flip frame 21 to continue to flip 90°, thereby completing the 180° flipping of the flip frame 21. The electric push rod 14 carries the lifting plate 13 and combines with the spring 16 to control the stop position of the movable block 15 during the descent or ascent process, so as to realize the fixation of any flip angle of the lithium battery, which is convenient for multi-angle detection and processing.

[0045] A hydraulic cylinder barrel 46 is fixedly installed on the top of the fixed partition 11, and a piston block 47 is slidably connected inside the hydraulic cylinder barrel 46. A connecting pipe 48 is fixedly connected between the hydraulic cylinder barrel 46 and one of the hydraulic cylinder barrels 45. The multiple hydraulic cylinder barrels 45 are connected through connecting pipes 49. The hydraulic oil in the hydraulic cylinder barrel 46 is injected into the interior of one of the hydraulic cylinder barrels 45 through the connecting pipe 48 by the sliding of the piston block 47 in the hydraulic cylinder barrel 46, and then injected into the interiors of the remaining hydraulic cylinder barrels 45 through the connecting pipes 49;

[0046] Combined with the cooperation between the upper limit slide plate of the clamp plate 1 41 and the slide groove 1, and the cooperation between the upper limit slider of the clamp plate 2 42 and the slide groove 2, multiple piston blocks 1 44 are combined with the piston rod 43 to push the clamp plate 1 41 and the clamp plate 2 42 to move, and combined with the inner walls on both sides of the flip frame 21, multiple lithium battery cells distributed in a rectangular array in the vertical and horizontal directions are clamped and fixed in a multi-faceted stable manner.

[0047] A piston tube 410 is fixedly connected to one side of the piston block 47, and an adjusting rod 411 is slidably connected to the piston tube 410, a U-shaped plate 412 is fixedly connected to the adjusting rod 411, and the inner walls of both sides of the U-shaped plate 412 are slidably connected to the movable plate 12 to improve the stability of the U-shaped plate 412 during horizontal movement, a guide pin is fixedly connected to the U-shaped plate 412, and a guide groove 18 slidably connected to the guide pin is provided on the movable plate 12, and the guide groove 18 includes a vertical section and an oblique section smoothly transitioned and connected to the bottom of the vertical section;

[0048] An adjusting pin is inserted into the adjusting rod 411, and a plurality of adjusting holes adapted to the adjusting pin are equidistantly provided on the piston tube 410. The cross section of the adjusting pin is a T-shaped structure (its shape feature is not specifically shown in the figure), and the end of the adjusting pin is limited by an R-shaped pin after passing through the piston tube 410 to prevent the adjusting pin from being separated from the adjusting rod 411 and the piston tube 410;

[0049] An adjustment port is provided on one side of the fixing platform 1 above the fixing partition 11, which is used to plug the adjustment pin into the adjustment holes at different positions on the piston tube 410, and adjust the initial content of the hydraulic oil in the hydraulic cylinder barrel 2 46 and the hydraulic cylinder barrel 1 45, so as to change the initial positions of the clamping front clamping plate 1 41 and the clamping plate 2 42, and realize the clamping effect in the assembly process of lithium batteries of different sizes;

[0050] A plurality of lithium battery cells distributed in a rectangular array in the vertical and horizontal directions are placed in the flip frame 21 and supported by the receiving plate 3. The electric push rod 14 pushes the lifting plate 13 to carry the movable plate 12 to move downward. At this time, the guide pin on the U-shaped plate 412 slides in the oblique section in the guide groove 18, and along with the downward movement of the movable plate 12, the U-shaped plate 412 is pushed to slide in the hydraulic cylinder barrel 2 46 through the adjusting rod 411 and the piston tube 410 carrying the piston block 2 47 until the guide pin enters the vertical section in the guide groove 18, and the hydraulic oil in the hydraulic cylinder barrel 2 46 is injected into the interior of the plurality of hydraulic cylinder barrels 1 45 through the connecting pipe 1 48 and the connecting pipe 2 49, so that the clamping assembly 4 performs multi-sided stable clamping and fixing of the plurality of lithium battery cells.

[0051] A telescopic sleeve 31 is fixedly connected between each corner of the bottom of the receiving plate 3 and the fixed partition 11, which is used to limit the receiving plate 3 to move only in the up and down directions. A spring 2 32 is fixedly connected between the receiving plate 3 and the fixed partition 11 and on the outside of the telescopic sleeve 31. The spring 2 32 provides an elastic supporting force for the receiving plate 3 to ensure the receiving effect of multiple lithium battery cells before clamping.

[0052] Example 2: Please refer to Figure 7-Figure 9 As shown, after the stable clamping is completed, the elastic support force provided by the two springs to the receiving plate is only used, and the problem that the clamping assembly cannot be combined to provide a stable anti-slip fixing effect during the subsequent assembly of the lithium battery can be solved by the following solution;

[0053] In this embodiment, a T-shaped groove is provided at the bottom of the receiving plate 3, and a T-shaped block 34 sliding therewith is fixedly connected in the T-shaped groove through a spring 33, an L-shaped limit block 35 is fixedly connected to the bottom of the T-shaped block 34, and a limit plate 413 slidingly connected to the fixed partition 11 is fixedly connected to the adjusting rod 411;

[0054] After the adjusting rod 411 is horizontally moved by the guide groove 18 on the movable plate 12 in combination with the guide pin, the limiting plate 413 follows the adjusting rod 411 and moves to the bottom of the L-shaped limiting block 35, and in combination with the limiting of the multiple sets of telescopic sleeve rods 31, the receiving plate 3 is stably supported, so that the multiple lithium battery cells can be connected in series and parallel by spot welding, and the whole assembly of the multiple lithium battery cells above the flip frame 21 is wrapped with tape;

[0055] In addition, the setting of the limit plate 413 can offset the downward pressure force generated on the end of the adjusting rod 411 during the guiding process of the guide groove 18 on the guide pin, thereby reducing the contact force between the piston block 47 and the hydraulic cylinder barrel 46 and increasing the service life of the piston block 47.

[0056] A linkage plate 19 is fixedly connected to the top of one side of the movable plate 12, and a guide slope 36 is fixedly provided on the inner side of the corner of the L-shaped limit block 35. After the clamping and assembly of the lithium battery is completed, the electric push rod 14 drives the lifting plate 13 to carry the movable plate 12 to continue to move downward, and the vertical section in the guide groove 18 restricts the guide pin, so as to continuously ensure that the clamping plate 1 41 and the clamping plate 2 42 can stably clamp the battery cell;

[0057] Then, the linkage plate 19 on the movable plate 12 contacts the guide slope 36 on the L-shaped limit block 35. Under the guidance of the guide slope 36, the L-shaped limit block 35 is forced to move horizontally and drive the T-shaped block 34 to compress the spring three 33. The L-shaped limit block 35 is separated from the limit plate 413. Then, the linkage plate 19 contacts the horizontal section on the L-shaped limit block 35 to drive the receiving plate 3 to move downward to avoid interference with the flipping of the flip frame 21.

[0058] Example 3: Please refer to Figure 1-Figure 9 As shown, the present invention also provides a method for using a lithium battery assembly multi-angle flip device with an anti-drop mechanism, comprising the following steps:

[0059] Step 1: Place multiple lithium battery cells in the flip frame 21, and receive the bottom of the multiple lithium battery cells through the receiving plate 3, the electric push rod 14 pushes the lifting plate 13 to carry the movable plate 12 to move downward, at this time, the guide pin on the U-shaped plate 412 slides in the oblique section in the guide groove 18, and with the downward movement of the movable plate 12, pushes the U-shaped plate 412 to slide in the hydraulic cylinder barrel 46 with the piston block 2 47 through the adjusting rod 411 and the piston tube 410;

[0060] Until the guide pin enters the vertical section of the guide groove 18, the hydraulic oil in the hydraulic cylinder barrel 2 46 is injected into the interior of the plurality of hydraulic cylinder barrels 1 45 through the connecting pipe 1 48 and the connecting pipe 2 49, so that the plurality of piston blocks 1 44 in combination with the piston rod 43 push the clamping plate 1 41 and the clamping plate 2 42 to move, and in combination with the inner walls on both sides of the flip frame 21, the plurality of lithium battery cells are clamped and fixed;

[0061] Step 2: Driven by the adjusting rod 411, the limiting plate 413 moves to the bottom of the L-shaped limiting block 35, and combined with the limiting of the multiple sets of telescopic sleeve rods 31, the receiving plate 3 is stably supported, so that the multiple lithium battery cells can be connected in series and parallel by spot welding, and the whole assembly of the multiple lithium battery cells above the flip frame 21 is wrapped with tape;

[0062] Step 3: By plugging the adjustment pin on the adjustment rod 411 into the adjustment holes at different positions on the piston tube 410, the initial positions of the clamping front clamping plate 1 41 and the clamping plate 2 42 can be changed, thereby achieving the clamping and flipping effect during the assembly of lithium batteries of different sizes;

[0063] Step 4: The electric push rod 14 drives the lifting plate 13 to carry the movable plate 12 to continuously move downward, and the vertical section in the guide groove 18 restricts the guide pin to continuously ensure that the clamping plate 1 41 and the clamping plate 2 42 stably clamp the battery cell. The linkage plate 19 on the movable plate 12 cooperates with the guide slope 36 on the L-shaped limit block 35, forcing the L-shaped limit block 35 to move horizontally to compress the spring 3 33 and separate from the limit plate 413. After that, the linkage plate 19 contacts the horizontal section on the L-shaped limit block 35, driving the receiving plate 3 to compress the spring 2 32 downward to avoid interference with the flipping of the flip frame 21.

[0064] Step 5: Then the lifting plate 13 contacts the pushing plate 17, driving the movable block 15 to compress the spring 16, and then as the lifting plate 13 rises, the movable block 15 returns to its original position and moves upward under the compression elasticity of the spring 16. In this process, the two groups of levers 24 are driven by the pull rod 28 and the connecting rod 27 to first lift and then press down the flip frame 21, and with the cooperation of the auxiliary rod 25, the flip frame 21 is flipped 180°;

[0065] During the flipping process, the electric push rod 14 can be stopped at any time to fix the flipping angle of the lithium battery, which is convenient for multi-angle detection and processing. The movable plate 12 is then driven by the electric push rod 14 to move upward, and the clamping plate 1 41, the clamping plate 2 42, the L-shaped limit block 35 and the receiving plate 3 are reset to lift the flipped lithium battery. The whole assembly of multiple lithium battery cells located above the flip frame 21 is wrapped with tape to complete the assembly processing of the lithium battery cells.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
