Description

Technical Field

[0001] This invention belongs to the field of battery testing technology, and in particular relates to a lithium battery testing and flipping device. Background Technology

[0002] After production, batteries need to undergo various tests to determine whether they meet performance requirements. During the testing process, lithium batteries need to be frequently rotated for wiring harness connections and to check for leaks.

[0003] Chinese Patent Application Publication No. CN113401627A discloses an automatic flipping and pitch-changing device for soft-pack batteries. Multiple battery flipping components are mounted on a chassis, capable of sliding on the chassis. A cam-driven power assembly is fixed to the chassis to drive each battery flipping component to slide on the chassis. When using this invention, the battery flipping components clamp and fix the battery and can rotate the battery at a certain angle. The cam-driven power assembly drives each battery flipping component to slide on the chassis, causing the battery flipping components to move away from or towards each other. This flipping and pitch-changing structure can simultaneously realize the pitch change and flipping of the battery at the same workstation, reducing equipment space occupation, shortening battery transportation distance, and improving battery processing efficiency. However, in the above flipping method, when the battery is not unloaded, the flipping device is in an idling state, which easily leads to a waste of flipping resources. Furthermore, the multi-station battery flipping components lack linkage and adjustability during flipping, failing to meet the adjustment and processing needs of multi-angle flipping during battery testing, indicating room for improvement. Summary of the Invention

Multiple limiting blocks are rotatably connected to the support ring in a circumferential direction, and the limiting blocks are inserted into the ratchet limiting tooth groove to limit the unidirectional rotation of the ratchet ring. Multiple limiting springs are fixedly connected to the support ring in a circumferential direction. The other end of the limiting spring 805 is fixedly installed on one side of the limiting block 804, and the multiple limiting springs 805 and multiple limiting blocks 804 are arranged one-to-one.

[0014] As a further description of the above technical solution:

[0015] The flipping mechanism includes a first fixed plate, which is fixedly installed on one side of the outer wall of the protective frame. Support sleeves are fixedly connected to both sides of the top of the first fixed plate, and a moving rod is slidably connected inside the support sleeves on both sides. A push cylinder is fixedly installed at one end of the moving rod. The bottom of the push cylinder is fixedly installed on one side of the outer wall of the first fixed plate through a mounting plate. A third spring is sleeved on the outer side of the other end of the moving rod, and the two ends of the third spring are fixedly connected to the support sleeve and one side of the end of the moving rod, respectively. Multiple drive racks are provided on the outer wall of the moving rod, and the drive racks are located at the bottom of the driven adjusting gear.

[0016] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

The material discharge belt is located at the bottom of the protective frame and the material drop trough.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, when testing is required, after the battery is placed into the fixture frame by an external loading robotic arm, the first electric push rods on both sides can drive the push plate to clamp and limit the side wall of the battery. After the battery is in place, the fixture frame can pull the placement plate downward by a rotating rod on one side. The driven adjusting gear on one side of the fixture frame can move downward and mesh with the drive rack at the corresponding position at the bottom. Pushing the cylinder can drive the moving rod and the drive rack to move. The movement of the drive rack can drive the meshed driven adjusting gear to rotate. The rotation of the driven adjusting gear can drive the rear fixture frame and the inner battery to flip. The meshing control of the flipping transmission is achieved by the battery's own gravity, which is beneficial to realize the transmission flipping control of the multi-station fixture frame after the battery is placed, avoid the idle consumption of the multi-station fixture frame, meet the testing and processing needs in multi-station testing, and improve the flipping efficiency of testing and processing.

[0024] 2. In this invention, through the designed ratchet limiting mechanism, when the drive rack drives the driven adjusting gear and the inner connected support ring to rotate, the support ring can contact the ratchet limiting tooth groove through the limiting block to drive the rear ratchet ring to rotate. The ratchet ring can drive the rear rotating rod, the fixture frame, and the inner battery to rotate. By setting the ratchet limiting mechanism, the adaptation to the single-sided transmission of the drive rack is realized, which is convenient for controlling the drive rack to reset after adjustment. Furthermore, because the limiting directions of the ratchet rings on both sides are different, it is beneficial to readjust the angle of the fixture frame through the angle adjustment mechanism on the other side after the flipping mechanism has flipped and adjusted. This facilitates independent control of the appropriate test angle for a single workstation and improves the adaptability of the test angle adjustment.

[0025] 3. In this invention, the designed drive rack allows the driven adjusting gear to slide outside the moving rod when it moves downward and contacts the teeth of the drive rack. When the driven adjusting gear and the teeth of the drive rack do not match, the continuous pressing force can cause the drive rack to slide outside the moving rod. The partially displaced drive rack can buffer the impact of the material falling from the driven adjusting gear and fully mesh with the teeth of the driven adjusting gear, thereby improving the meshing stability of the material falling from the driven adjusting gear and avoiding the impact of non-meshing on the flipping and positioning effect.

[0026] 4. Through the designed angle adjustment mechanism, after the flipping mechanism flips the fixture frame, the second electric push rod of the other side angle adjustment mechanism can extend and drive the hinge block to move upward. The upward movement of the hinge block can drive the push plate to push the connecting rod and the flipping disk to rotate. The rotation of the flipping disk can drive the support ring and ratchet ring on this side to rotate the rotating rod and the fixture frame in the direction that can drive the rotation. When the fixture frame rotates, the ratchet ring on the other side and the driven adjustment gear can idle through the ratchet structure to avoid affecting the position maintenance of the driven adjustment gear and the rest of the fixture frame. The fixture frame that can be flipped in reverse independently improves the stability of handling multi-station fixture frames during testing. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-7 and Figure 10 The present invention provides a technical solution: a lithium battery test flipping device, including a support frame 1, a protective frame 2 fixedly installed on the top of the support frame 1, and a plurality of clamping mechanisms 3 slidably connected to the inner cavity of the protective frame 2;

[0041] The clamping mechanism 3 includes a clamping frame 301, with rotating rods 306 fixedly connected to both sides of the clamping frame 301. The rotating rods 306 are slidably connected to grooves opened on both sides of the inner cavity of the protective frame 2. A positioning mechanism 4 is sleeved on the outside of each rotating rod 306, and the positioning mechanism 4 is fixedly installed on one side of the inner cavity of the protective frame 2. Each rotating rod 306 is equipped with a ratchet limiting mechanism 8, and each ratchet limiting mechanism 8 is respectively fixedly mounted with a driven adjusting gear 9 and an angle adjusting mechanism 6. The ratchet limiting mechanisms 8 limit rotation in opposite directions, used to limit the transmission direction through the ratchet limiting mechanisms 8. The angle adjusting mechanism 6 is fixedly installed... On one side of the positioning mechanism 4, a flipping mechanism 5 is fixedly installed on one side of the outer wall of the protective frame 2. The flipping mechanism 5 is located at the bottom of multiple driven adjusting gears 9 and is used for meshing transmission after the battery is positioned inside the protective frame 2. Two guide rods 302 are fixedly connected to both sides of the inner cavity of the clamp frame 301, and a support plate 303 is connected between two adjacent guide rods 302. A first electric push rod 304 is fixedly installed on one side of the support plate 303. A push plate 305 is fixedly installed at one end of the output shaft of the first electric push rod 304. An arc-shaped fitting part is provided on one side of the push plate 305. The positioning mechanism 4 includes a positioning plate 401, and the positioning plate 401 is sleeved with On the outer side of the rotating rod 306 at the corresponding position, telescopic rods 402 are fixedly connected to both sides of the bottom of the positioning plate 401. The bottom end of the telescopic rod 402 is fixedly connected to the bottom of the inner cavity of the protective frame 2. A first spring 403 is sleeved on the outer wall of the telescopic rod 402. The two ends of the first spring 403 are fixedly connected to the bottom of the positioning plate 401 and the outer side of the fixed part of the telescopic rod 402, respectively. The flipping mechanism 5 includes a first fixing plate 501, which is fixedly installed on one side of the outer wall of the protective frame 2. Support sleeves 509 are fixedly connected to both sides of the top of the first fixing plate 501, and moving rods 502 are slidably connected inside the support sleeves 509 on both sides. Furthermore, a push cylinder 506 is fixedly installed at one end of the moving rod 502. The bottom of the push cylinder 506 is fixedly installed on one side of the outer wall of the first fixed plate 501 through the mounting plate 507. A third spring 508 is sleeved on the outer side of the other end of the moving rod 502. The two ends of the third spring 508 are fixedly connected to the support sleeve 509 and one side of the end of the moving rod 502, respectively. Multiple drive racks 503 are provided on the outer wall of the moving rod 502. The drive racks 503 are located at the bottom of the driven adjusting gear 9. Through the designed third spring 508, the transmission stability of the moving rod 502 can be guaranteed, and the moving rod 502 can be prevented from shaking or deviating.

[0042] The specific implementation method is as follows: When testing is required, after the battery is placed into the clamp frame 301 by an external loading robotic arm, the push plate 305 can be driven by the first electric push rods 304 on both sides to clamp and limit the side wall of the battery. Furthermore, the designed arc-shaped fitting part ensures the clamping and fitting friction between the push plate 305 and the side wall of the battery, preventing slippage. Simultaneously, after the battery is positioned, the clamp frame 301 can pull the positioning plate 401 downwards via a rotating rod 306 on one side. The downward movement of the positioning plate 401 compresses the telescopic rod 402 and the external first spring 403. The first spring 403 can absorb the impact generated during the top positioning using its own elasticity, and the clamp frame 301 moves downwards under the weight of the battery. When the 1 and the positioning plate 401 are in place, the driven adjusting gear 9 on one side of the fixture frame 301 can move downward and mesh with the drive rack 503 at the corresponding position at the bottom. The cylinder 506 is pushed to work, which can drive the moving rod 502 and the drive rack 503 to move. The movement of the drive rack 503 can drive the meshed driven adjusting gear 9 to rotate. The rotation of the driven adjusting gear 9 can drive the rear fixture frame 301 and the inner battery to flip. Thus, the meshing control of the flipping transmission can be achieved by the weight of the battery itself. This is beneficial to realize the transmission flipping control of the multi-station fixture frame 301 after the battery is positioned, avoid the idle consumption of the multi-station fixture frame 301, meet the testing and processing needs in the multi-station testing situation, and improve the testing and processing flipping efficiency.

[0043] Please see Figures 1-2 and Figures 8-9 The ratchet limiting mechanism 8 includes a ratchet ring 801. A ratchet limiting tooth groove is provided on one side of the ratchet ring 801, and the ratchet ring 801 is fixedly connected to one side of the rotating rod 306. A support ring 803 is rotatably connected to the inner cavity of the ratchet ring 801. Multiple connecting plates 802 are fixedly connected to one side of the support ring 803, and the connecting plates 802 are fixedly connected to one side of the driven adjusting gear 9 or the angle adjusting mechanism 6 at the corresponding position. Multiple limiting blocks 804 are rotatably connected to the support ring 803 in a circumferential direction, and the limiting blocks 804 are inserted into the ratchet limiting tooth groove to limit the unidirectional rotation of the ratchet ring 801. Multiple limiting springs 805 are fixedly connected to the support ring 803 in a circumferential direction, and the other end of the limiting spring 805 is fixedly installed on one side of the limiting block 804. The multiple limiting springs 805 and the multiple limiting blocks 804 are arranged one-to-one.

[0044] The specific implementation method is as follows: Through the designed ratchet limiting mechanism 8, when the drive rack 503 drives the driven adjusting gear 9 and the inner connected support ring 803 to rotate, the support ring 803 can contact the ratchet limiting tooth groove through the limiting block 804 to drive the rear ratchet ring 801 to rotate. The ratchet ring 801 can drive the rear rotating rod 306, the fixture frame 301 and the inner battery to rotate. Thus, the ratchet limiting mechanism 8 can be set to adapt to the single-sided transmission of the drive rack 503, which is convenient to control the drive rack 503 to reset after adjustment. Furthermore, because the limiting directions of the two ratchet rings 801 are different, it is beneficial to readjust the angle of the fixture frame 301 through the other side angle adjustment mechanism 6 after the flipping mechanism 5 flips and adjusts. This facilitates independent control of the adapted test angle and improves the adaptability of the test angle adjustment.

[0045] Please see Figure 1-7 A sliding hole is provided on one side of the drive rack 503, and the drive rack 503 is slidably connected to the outside of the moving rod 502 by a slider. Both sides of the drive rack 503 are fixedly connected to the second fixing plate 504 by the second spring 505. The second fixing plate 504 is fixedly connected to the outside of the moving rod 502.

[0046] The specific implementation method is as follows: When the driven adjusting gear 9 moves downward and contacts the teeth of the drive rack 503, when the driven adjusting gear 9 and the teeth of the drive rack 503 do not match, the continuous pressing force of the falling position can drive the drive rack 503 to slide outside the moving rod 502. The partially displaced drive rack 503 can buffer the impact of the material falling from the driven adjusting gear 9, and can fully mesh with the teeth of the driven adjusting gear 9, thereby improving the meshing stability of the driven adjusting gear 9 and the drive rack 503 when falling, and avoiding the impact of non-meshing on the flipping positioning effect.

[0047] The angle adjustment mechanism 6 includes a flipping plate 601, which is fixedly connected to a support ring 803 and a connecting plate 802 at a corresponding position. A connecting rod 602 is hinged to one side of the flipping plate 601 via a pin, and a push plate 603 is hinged to the other end of the connecting rod 602. A hinge block 604 is hinged to the bottom of the push plate 603 via a pin, and a second electric push rod 605 is fixedly connected to the bottom of the hinge block 604. A connecting seat 606 is fixedly connected to the bottom of the second electric push rod 605, and a connecting seat 606 is fixedly connected to one side of the landing plate 401. A material dropping groove for the battery to fall into is opened at the bottom of the inner cavity of the protective frame 2, and a discharge belt 7 is fixedly installed inside the support frame 1. The discharge belt 7 is located at the bottom of the protective frame 2 and the material dropping groove.

[0048] The specific implementation method is as follows: Through the designed angle adjustment mechanism 6, when the flipping mechanism 5 flips the fixture frame 301, the second electric push rod 605 of the other side angle adjustment mechanism 6 can extend and drive the hinge block 604 to move upward. The upward movement of the hinge block 604 can drive the push plate 603 to move upward. The movement of the push plate 603 can drive the connecting rod 602 and the flipping disk to rotate. The rotation of the flipping disk 601 can drive the support ring 803 and the ratchet ring 801 on this side to rotate the rotating rod 306 and the fixture frame 301 in the direction that can drive the rotation. When the fixture frame 301 rotates, the ratchet ring 801 on the other side and the driven adjustment gear 9 can rotate freely through the ratchet structure to avoid affecting the position maintenance of the bottom driven adjustment gear 9 and the other fixture frames 301. By using the fixture frame 301 that can be flipped in reverse independently, the processing stability of the multi-station fixture frame 301 during testing is improved.

[0049] Working principle: During use, when a lithium battery needs to be tested, the external loading robotic arm places the battery into the clamp frame 301. The first electric push rods 304 on both sides then drive the push plate 305 to clamp and limit the battery's sidewalls. After the battery is positioned, the clamp frame 301 pulls the positioning plate 401 downwards via a rotating rod 306 on one side. The downward movement of the positioning plate 401 compresses the telescopic rod 402 and the external first spring 403. The first spring 403 absorbs the impact generated during the top positioning using its own elasticity. The battery's gravity moves the fixture frame 301 and the positioning plate 401 downwards. The driven adjusting gear 9 on one side of the fixture frame 301 moves downwards and meshes with the drive rack 503 at the corresponding position at the bottom. This pushes the cylinder 506 to work, causing the moving rod 502 and the drive rack 503 to move. The drive rack 503 moves, causing the meshed driven adjusting gear 9 to rotate. The rotation of the driven adjusting gear 9 causes the rear fixture frame 301 and the inner battery to flip over. Thus, the battery's own gravity is used to achieve meshing control of the flipping transmission.

[0050] When the drive rack 503 drives the driven adjusting gear 9 and the inner connected support ring 803 to rotate, the support ring 803 contacts the ratchet limiting tooth groove through the limiting block 804, causing the rear ratchet ring 801 to rotate. The ratchet ring 801 drives the rear rotating rod 306, the clamp frame 301 and the inner battery to rotate. Through the setting of the ratchet limiting mechanism 8, the adaptation to the single-sided transmission of the drive rack 503 is realized, which makes it convenient to control the drive rack 503 to reset after adjustment.

[0051] When the driven adjusting gear 9 moves downward and contacts the teeth of the drive rack 503, when the driven adjusting gear 9 and the teeth of the drive rack 503 do not match, the continuous pressing force of the falling drive rack 503 causes the drive rack 503 to slide outside the moving rod 502. The partially displaced drive rack 503 buffers the impact of the falling material from the driven adjusting gear 9 and fully meshes with the teeth of the driven adjusting gear 9.

[0052] When the flipping mechanism 5 flips the fixture frame 301, the second electric push rod 605 of the angle adjustment mechanism 6 on the other side extends and drives the hinge block 604 to move upward. The upward movement of the hinge block 604 drives the push plate 603 to move upward. The movement of the push plate 603 drives the connecting rod 602 and the flipping disk to rotate. The rotation of the flipping disk 601 drives the support ring 803 and ratchet ring 801 on this side to rotate the rotating rod 306 and the fixture frame 301 in the direction of rotation. When the fixture frame 301 rotates, the ratchet ring 801 on the other side and the driven adjusting gear 9 rotate freely through the ratchet structure to avoid affecting the position maintenance of the driven adjusting gear 9 and the rest of the fixture frame 301.
