DETAILED DESCRIPTION

[0030] See also Figure 1-Figure 11 In an embodiment of the present invention, a lithium battery processing equipment comprises a test support frame 1 and a protective frame 2; preferably, a telescopic cylinder 3 is installed on the top of the test support frame 1, and a top plate 4 is fixedly installed on the bottom output end of the telescopic cylinder 3. The lifting and lowering of the top plate 4 can be controlled by the telescopic cylinder 3, so as to facilitate the height control of the clamping and drop test of the lithium battery to be tested. A guide block 14 is provided on the top of the top plate 4 diagonally and parallel to the sliding guide block 14. A clamping rod for clamping the lithium battery to be tested is elastically connected to the guide block 14 through a spring. A fixing component for fixing the lithium battery to be tested is provided at the bottom end of the clamping rod. When in use, The lithium battery to be tested is clamped and fixed by the fixing assembly, and then the height of the lithium battery required for the experiment is controlled by the telescopic cylinder 3. A driving mechanism for driving the clamping rod to move is provided on the top of the top plate 4. When the corresponding height is reached, the angle of the clamped lithium battery can be adjusted by the driving mechanism, so that the experiment is targeted. The protective frame 2 is arranged directly below the top plate 4. The protective frame 2 can be made of transparent material, so that when performing a lithium battery drop detection, the changes in the lithium battery can be better observed, and the protective frame 2 can also block the debris generated by the lithium battery falling, thereby preventing the debris from splashing.

[0031] See also Figure 2-Figure 7Preferably, the clamping rod includes a first support rod 7; the top end of the first support rod 7 is elastically slidably connected to the guide block 14 by a spring, and the outer periphery of the end of the first support rod 7 away from the top plate 4 is slidably connected to the sleeve 6, and the bottom end of the sleeve 6 is rotatably connected to the second support rod 8, and the fixing component is arranged at the end of the second support rod 8 away from the sleeve 6; the bottom of the inner wall of the sleeve 6 is fixedly connected to a pull rope 12, and the end of the pull rope 12 away from the sleeve 6 slides through the side wall of the first support rod 7 and is transmission-connected to the driving mechanism. When in use, when the pull rope 12 is reeled in by the driving mechanism, the pull rope 12 can make the sleeve 6 move in the direction of the first support rod 7, thereby making the second support rod 8 move upward, and then making one end of the clamped lithium battery move upward, so that the bottom side of the lithium battery contacts the landing point first in the subsequent drop test, thereby achieving the targetedness of the experiment.

[0032] Further, preferably, a movable groove is opened on one side opposite to the two groups of first support rods 7, and a limit plate 21 is slidably arranged in the movable groove. The two sides of the limit plate 21 are slidably connected to the movable groove through sliders and slide grooves, so as to provide support on the limit plate 21. The top of the limit plate 21 is elastically connected to a mounting plate 23 through a spring, and the two ends of the mounting plate 23 are fixedly connected to the end of the first support rod 7. The setting of the mounting plate 23 provides the limit plate 21 with an automatic reset function. A plurality of groups of limit holes are arranged in an array on the limit plate 21, and a limit column 211 adapted to the limit hole is fixedly arranged on the top of the inner wall of the sleeve 6. The end of the limiting column 211 is set as a semicircular structure, so that the limiting column 211 and the limiting hole are adapted more smoothly. A first telescopic hose 22 is fixedly arranged between the top of the limiting plate 21 and the mounting plate 23. The end of the first telescopic hose 22 away from the limiting plate 21 is fixedly connected to the third connecting pipe 20. The end of the third connecting pipe 20 away from the first telescopic hose 22 is transmission-connected to the driving mechanism. When the driving mechanism is pressed down, gas will be input into the first telescopic hose 22 through the third connecting pipe 20, so that the first telescopic hose 22 expands, and then the limiting plate 21 is pushed in the direction away from the limiting column 211.

[0033] When in use, in the initial state, the first support rod 7, the sleeve 6, and the second support rod 8 are in a vertical state and at the farthest end relative to the two groups of guide blocks 14. The limiting plate 21 is close to the position of the sleeve 6 under the action of its corresponding spring. At this time, the relative position between the sleeve 6 and the first support rod 7 is limited by the limiting plate 21 and the limiting column 211, the first telescopic hose 22 is in a contracted state, and the fixing components are at the same level; when performing a lithium battery drop detection, the lithium battery is placed under the top plate 4, and then the telescopic cylinder 3 is started to push the top plate 4 downward, and then the second support rod 8 is pushed to move toward the lithium battery, and through The lithium battery is fixed by the fixing assembly, and then the telescopic cylinder 3 is started to drive the top plate 4 to move upward to the corresponding height, and the clamped lithium battery is adjusted to the required angle by the driving mechanism; for example, the placed lithium battery has a wide side corresponding to the fixing assembly. At this time, in order to achieve a state in which a wide side of the bottom of the lithium battery touches the ground first, the driving mechanism can be pressed downward and then rotated to drive the lithium battery to tilt to one side, thereby achieving the state in which the required specific side touches the ground first. When the driving mechanism is pressed downward, the driving mechanism will transport gas to the first telescopic hose 22 through the third connecting pipe 20 to expand it, thereby pushing the limiting mechanism. The positioning plate 21 moves into the sliding groove, so that the first support rod 7 and the sleeve 6 have the conditions for relative movement, and the rotating driving mechanism can form a reel for the pull rope 12, thereby causing the sleeve 6 to move upward, and the upward movement of the sleeve 6 drives the second support rod 8 to move upward. At this time, when the driving mechanism drives one set of limiting plates 21 to separate from the limiting column 211, the other set of limiting plates 21 and the limiting column 211 are still in a matching state, so that the other set of sleeves 6 and the first support rod 7 cannot move relative to each other. Therefore, when one set of sleeves 6 and the second support rod 8 corresponding to the first support rod 7 move upward and then through the fixing assembly, One side of the lithium battery moves upward, and since the sleeve 6 and the second support rod 8 are rotatably connected, the two sets of sleeves 6 and the second support rod 8 will automatically adapt to the angle of the lithium battery, so that the lithium battery is tilted and the required side touches the ground first, which is beneficial to the operation of the lithium battery detection experiment. After the angle adjustment is completed, the driving mechanism is first pulled upward to shrink the first telescopic hose 22, and then the limit plate 21 is allowed to complete the limiting cooperation with the limit column 211 under the action of the first telescopic hose 22 and its corresponding spring, thereby limiting the position of the tilted lithium battery, thereby facilitating subsequent detection experiment operations.

[0034] See also Figure 2-Figure 5 , Fig.11Preferably, the fixing assembly includes a support column 11; the support column 11 is slidably arranged at the end of the second support rod 8 away from the sleeve 6, and the end of the support column 11 close to the top plate 4 is fixedly connected with a suction cup 9, through which the lithium battery is adsorbed and fixed, and the suction cup 9 can be deformed to a certain extent, and the end of the support column 11 away from the suction cup 9 is rotatably connected with a first connecting tube 10, and two groups of intersecting connecting channels 18 are arranged in the side wall of the top plate 4, and the two groups of connecting channels 18 intersect at one end away from the guide block 14, and the end where the two groups of connecting channels 18 intersect is provided with a connecting groove 191 connected to the outside, and a sealing member 19 is elastically connected to the connecting groove 191 through a spring, and the sealing member 19 and the connecting groove 191 are sealed and slidably connected, and the first connecting tube 10 is away from One end of the support column 11 is fixedly connected to an end of the connecting channel 18 away from the sealing piece 19. During use, when the suction cup 9 is not adapted to the lithium battery, the sealing piece 19 blocks the connecting groove 191 under the action of the spring, thereby making the connecting channel 18 disconnected from the outside. At this time, the lithium battery can be adsorbed and fixed by the suction cup 9. When it is necessary to release the fixation of the lithium battery by the suction cup 9, the sealing piece 19 is pressed in the direction of the connecting channel 18 to separate the sealing piece 19 from the port of the connecting groove 191, thereby making the connecting channel 18 connected to the outside through the connecting groove 191, so that the negative pressure in the suction cup 9 changes to normal, and then the lithium battery falls down under the action of its own gravity to complete the drop detection, and then the sealing piece 19 automatically resets under the action of the spring.

[0035] See also Figure 8-Figure 9Preferably, the outer wall of the support column 11 is provided with multiple groups of strip grooves in an annular array, and the inner wall of the end of the second support rod 8 away from the sleeve 6 is rotatably connected to a limiting ring 25, and the inner ring side wall of the limiting ring 25 is fixedly connected with a strip block that slides and fits with the strip groove. Through the cooperation of the strip groove and the strip block, the support column 11 will not fall off the second support rod 8 under the restriction of the limiting ring 25; the outer ring side wall of the limiting ring 25 is provided with multiple groups of circular holes in an annular array, and the side wall of the second support rod 8 is elastically connected with a fixing column 26 that slides and fits with the circular hole. The top of the fixing column 26 and the side away from the suction cup 9 are fixedly connected with a cross plate, and the bottom of the cross plate is fixedly connected with a second telescopic hose 27, and the bottom of the second telescopic hose 27 is fixedly connected to the inner wall of the second support rod 8, and the side of the second telescopic hose 27 away from the suction cup 9 is fixedly connected with a second connecting pipe 13, and the second connecting pipe 13 is away from the second telescopic hose 27 One end passes through the side wall of the top plate 4 and is connected to the driving mechanism for transmission. When the driving mechanism transports gas into the second connecting pipe 13, the gas will enter the second telescopic hose 27 through the second connecting pipe 13, causing the second telescopic hose 27 to expand upward, thereby pushing the cross plate to move upward. The upward movement of the cross plate causes the fixing column 26 to move upward and separate from the circular hole on the limiting ring 25, thereby allowing the support column 11 to rotate. At this time, if the wide side of the lithium battery corresponds to the suction cup 9, the two groups of sleeves 6 and the first support rod 7 can be driven by the driving mechanism to move in opposite directions, thereby realizing the lithium battery tilting left and right in the vertical direction; and when the fixing column 26 and the circular hole cooperate, the limiting ring 25 cannot rotate. At this time, the driving mechanism can reel in a group of pull ropes 12 separately, thereby causing a group of sleeves 6 to move upward, thereby causing the clamped lithium battery to tilt toward the direction of the other group of sleeves 6 and the first support rod 7.

[0036] See also Figure 1-Figure 3 , Figure 5 , Figure 8-Figure 10Preferably, the driving mechanism includes two groups of rotating rollers 24; the ends of the two groups of pull ropes 12 away from the sleeve 6 are respectively wound on the corresponding rotating rollers 24, and the pull ropes 12 can be wound or spread when the rotating rollers 24 rotate, so that the sleeve 6 can move upward or downward, and the top center of the rotating roller 24 is elastically connected to a square column through a spring, and the top of the square column is fixedly connected to a first knob 16. When the first knob 16 is rotated, the rotating roller 24 can be driven to rotate through the square column, and the bottom of the first knob 16 is sealed and rotatably connected with a sealing ring. The first knob 16 is sleeved on the top of the rotating roller 24 and is sealed and slidably connected. When the first knob 16 is rotated downward When moving, the gas between the first knob 16 and the rotating roller 24 can be transported to the sealing ring. Delivery pipes 29 are fixedly connected to both sides of the bottom of the sealing ring. The delivery pipes 29 are connected to the sealing ring, and the sealing ring is connected to the inside of the first knob 16. The end of the delivery pipe 29 away from the sealing ring is fixedly connected to the third connecting pipe 20. When the first knob 16 moves downward, the gas enters the delivery pipe 29 through the sealing ring, and then enters the third connecting pipe 20 through the delivery pipe 29, and finally is transported to the first telescopic hose 22 through the third connecting pipe 20 to expand it; the rotating roller 24 corresponds to the pull rope 12 one by one, and the bottom of the rotating roller 24 is rotatably connected to the top of the top plate 4.

[0037] It should be noted that: the guide block 14 is slidably set at the bottom of the top plate 4 through an elastic column, and is set diagonally and parallel. The clamping rod can move horizontally on the guide block 14 along the extension direction of the guide block 14, and the guide block 14 can be relatively close to or relatively far away from the top plate 4. In this way, when a group of clamping rods are driven away from or close to the top plate 4 by the driving mechanism, the clamping rod can slide on the guide block 14 to adapt to the width of the lithium battery after rotating in the direction of movement of a group of clamping rods. When the two groups of clamping rods are driven to move synchronously in opposite directions through the cooperation of the driving mechanism and the pull rope 12, the two groups of guide blocks 14 will be relatively close to or far away to adapt to the rotation state of the lithium battery in the vertical direction. In addition, the first connecting tube 10, the second connecting tube 13, and the third connecting tube 20 are all flexible hoses, and will not affect the movement of the clamping rod respectively.

[0038] Further, preferably, a toothed ring 28 is fixedly provided at the middle of the outer periphery of the rotating roller 24, and a gear 30 is slidably fitted on the top of the sealing ring. The sealing ring and the gear 30 are mutually abutted through a step-like structure, and the gear 30 is located above the sealing ring. In this way, when one set of first knobs 16 moves downward, the gear 30 will not move downward under the support of the sealing ring on the other set of first knobs 16. When the gear 30 moves downward, the two sets of first knobs 16 can be pushed to move downward synchronously, and the gear 30 is meshed with the two sets of toothed rings 28. The gear 30 and the toothed rings 28 are meshed. In meshing cooperation, the bottom of the gear 30 is fixedly connected with an airbag 15, and the top of the gear 30 is fixedly connected with a second knob 17. The end of the airbag 15 away from the second knob 17 is fixedly connected to the second connecting tube 13. When the gear 30 moves downward, the airbag 15 will be squeezed to shrink. The contraction of the airbag 15 causes the gas inside it to be transported to the outside into the second connecting tube 13. The outer periphery of the second knob 17 and the first knob 16 is provided with a protective box 5. The bottom of the protective box 5 is fixedly connected to the top of the top plate 4. The first knob 16 and the second knob 17 can be protected by the protective box 5.

[0039] During specific use, when the lithium battery is not tested, the two groups of first support rods 7 are at the farthest ends relative to the two groups of guide blocks 14 under the action of the spring, the limit plate 21 and the limit column 211 are limited and matched, the bottom heights of the two groups of second support rods 8 are consistent, the fixing column 26 limits the position of the limit ring 25, the gear 30 and the gear ring 28 are separated, the blocking piece 19 blocks the connecting groove 191, the first telescopic hose 22 and the second telescopic hose 27 are in a retracted state, and the lengths of the first connecting tube 10 and the second connecting tube 13 are sufficient for the relative movement of the sleeve 6 and the first support rod 7; when the lithium battery is subjected to a drop safety test, the lithium battery to be tested is adsorbed and fixed by the suction cup 9, and then moved to the corresponding height. After that, the lithium battery is adjusted according to the angle of the test required. When the wide side of the lithium battery corresponds to the two groups of suction cups 9 respectively, at this time, a group of first knobs 16 can be pressed down, so that the gas in the first knobs 16 is transported to the first telescopic hose 22 through the sealing ring, the delivery pipe 29, and the third connecting pipe 20, so that its expansion pushes the limit plate 21 to separate from the limit column 211, and then the first knob 16 is rotated so that the first knob 16 drives the rotating roller 24 to rotate to reel in a group of pull ropes 12, thereby causing a group of sleeves 6 to move upward. At this time, since the two groups of limiting rings 25 are both limited, the lithium battery will move upward through the second support rod 8, the support column 11, and the suction cup 9 under the action of the upward movement of a group of sleeves 6. When the first knob 16 is pressed down, the first knob 16 moves downward to push the gear 30 downward, thereby making the two sets of second knobs 17 move downward synchronously, and the gear 30 and the gear ring 28 mesh with each other. During this process, the gear 30 moves downward to squeeze the airbag 15, so that the gas in the airbag 15 is transported to the second telescopic hose 27 through the second connecting pipe 13, causing it to expand upward, thereby driving the fixed airbag 15 to move downward. The column 26 is separated from the circular hole, so that the limiting ring 25 has the condition to rotate, and the second knob 17 is turned downward to separate the two groups of limit plates 21 from the limit column 211, and then the first knob 16 is turned to make the gear 30 drive the two groups of gear rings 28 to rotate synchronously, thereby making the two groups of rotating rollers 24 rotate synchronously. When the two groups of rotating rollers 24 rotate synchronously, one group of rotating rollers 24 reels one group of pull ropes 12, and the other group of rotating rollers 24 spreads the other group of pull ropes 12, thereby realizing that one group of first support rods 7 moves upward and the other group of first support rods 7 moves downward. At this time, the support column 11 has the condition to rotate, so the lithium battery will rotate left and right in the vertical direction, presenting a state in which one of its narrow sides touches the ground first when it falls to the ground;After the angle adjustment of the lithium battery is completed, the second knob 17 or the first knob 16 is pulled up so that the limit plate 21 and the limit column 211 cooperate again to limit the sleeve 6 and the first support rod 7. Finally, the plugging member 19 is pressed to make the connection channel 18 communicate with the outside through the connection groove 191, and then the suction cup 9 releases the adsorption and fixing state of the lithium battery, so that the lithium battery can be dropped. The operation is simple. ;
