[0001] The present application relates to the field of gel electrolyte lithium battery, in particular to a gel electrolyte lithium battery processing equipment. BACKGROUND

[0002] The lithium battery electrolyte is the carrier of ion transmission in the battery, which is generally composed of lithium salt and organic solvent. The electrolyte plays a role in conducting ions between the positive and negative electrodes of the lithium battery, and is the guarantee for the lithium ion battery to obtain high voltage, high specific energy and other advantages. The electrolyte is generally prepared by mixing high-purity organic solvent, electrolyte lithium salt, and necessary additives under certain conditions and in a certain proportion.

Since the conventional battery core package needs to be manually taken out after actual liquid injection, the empty core package to be injected can be placed in the corresponding injection position, which leads to low overall injection efficiency. Therefore, we improve it and propose a gel electrolyte lithium battery processing equipment. SUMMARY

[0008] As the preferred technical scheme of the present application, one side of the plurality of driving wheels on the single connecting seat is jointly engaged with a toothed plate, and the surface of the connecting seat is further provided with an exposed groove. Wherein, the toothed plate can make the rotating rod drive the limiting seat to rotate after sliding in the interior of the connecting seat, so that the sealed battery core bag after liquid injection is rotated to the position corresponding to the exposed groove.

[0009] As the preferred technical scheme of the present application, the middle part of the connecting plate downwardly extends a supporting part, and the transmission structure comprises a transmission wheel movably arranged in the interior of the supporting part and a left toothed plate and a right toothed plate respectively engaged on both sides of the transmission wheel. Wherein, one end of the left toothed plate is fixed with one end of the toothed plate through a transmission rope.

[0010] As the preferred technical scheme of the present application, the surface of the transmission rope is provided with a guide wheel, and the bending part of the transmission rope can be guided in transmission under the action of the guide wheel.

[0011] As the preferred technical scheme of the present application, the transmission structure further comprises a sliding seat fixed on the bottom wall of the right toothed plate, and one end of the sliding seat penetrates through the exterior of the supporting part and is fixed with an upper driving protrusion. Wherein, the surface of the sliding seat is sleeved with a spring, and under the action of the spring force, the upper driving protrusion is made to slide in the direction away from the supporting part in the natural state.

Since the limiting seat and the exposed groove are in a non-corresponding state at this time, the connecting seat can effectively support the empty battery core package; In this way, when it rotates to the next station, the liquid injection operation can be performed. After the liquid injection and packaging are completed, the upper driving protrusion and the lower driving protrusion move to the transfer position. The transmission structure subjected to the resistance will drive the rotating rod and the limiting seat thereon to rotate, so that the limiting seat rotates to the corresponding position of the exposed groove. In this way, the battery core package after liquid injection can directly fall into the collection box below. Therefore, it is not necessary to manually take out the battery core package and place a new battery core package, which saves the operation process and facilitates the improvement of overall processing efficiency.

[0022] Please refer to Figures 1 to 9 As shown in the drawings, the present application provides a technical solution: a gel electrolyte lithium battery processing equipment, comprising a processing bin 1, the bottom of the processing bin 1 is fixed with a rotating motor 11, the output end of the rotating motor 11 is connected with a support structure 2, a limiting piece 21 is arranged in the support structure 2 for placing a battery core package with liquid injection, and a transmission structure 3 is arranged in the inside of the support structure 2, and the limiting piece 21 can be rotated under the action of the transmission structure 3, so that the sealed battery core package after liquid injection is pushed to fall into a collection box 4; The side wall of the processing bin 1 is also fixed with a support plate 12, the support structure 2 and the collection box 4 are located above the support plate 12, the surface of the support plate 12 has a through groove penetrating the output end, the support plate 12 does not rotate synchronously with the output end, the surface of the support plate 12 has an annular groove 13, the center of the annular groove 13 is concentrically arranged with the rotation point of the output shaft, and a lower driving protrusion 14 is arranged in the annular groove 13 corresponding to the position of the collection box 4; The support structure 2 comprises a connecting disc 24 fixed to the output end of the rotating motor 11, connecting plates 22 distributed on the four sides of the connecting disc 24, and a connecting seat 23 fixed to the end of the connecting plate 22; The limiting piece 21 comprises a rotating rod 210 movably arranged on the surface of the connecting seat 23 and a limiting seat 211 fixed to the surface of the rotating rod 210, the limiting seat 211 is used for supporting the inserted core package, so as to avoid the core package from being placed on the connecting seat 23 in an inclined position, and the accuracy of subsequent liquid injection is ensured, one end of the rotating rod 210 extends into the inside of the connecting seat 23 and is fixed with a driven wheel 212, one side of the driven wheel 212 is engaged with a driving wheel 213 movably connected with the side wall of the connecting seat 23, and the driven wheel 212 and the driving wheel 213 can rotate in the inside of the connecting seat 23 without tilting and shaking; A toothed plate 214 is meshed with one side of the multiple driving wheels 213 on a single connecting seat 23. The surface of the connecting seat 23 is also provided with an exposure groove 230. The size of the exposure groove 230 is slightly larger than the size of the core-packed battery after liquid injection and packaging. The tooth plate 214 slides inside the connecting seat 23 to enable the rotating rod 210 to drive the limiting seat 211 to rotate, so that the battery core pack sealed after injection is rotated to a position corresponding to the exposing groove 230; A support portion 220 extends downward from the middle of the connecting plate 22, and the transmission structure 3 includes a transmission wheel 31 movably arranged inside the support portion 220 and a left tooth plate 32 and a right tooth plate 33 respectively engaged with both sides of the transmission wheel 31. Figure 7 As shown, the left tooth plate 32 and the right tooth plate 33 can only slide along the height direction of the support portion 220 without shaking left and right, thereby ensuring the accuracy of engagement with the transmission wheel 31; One end of the left tooth plate 32 is fixed to one end of the tooth plate 214 via a transmission rope 34; The transmission rope 34 is provided with a guide wheel 35 on its surface. The guide wheel 35 can guide the bending portion of the transmission rope 34. There are multiple guide wheels 35, which are distributed at the bending positions of the transmission rope 34, so as to guide the transmission rope 34 in the transmission state to meet the actual power transmission requirements. The transmission structure 3 further includes a sliding seat 36 fixed to the bottom wall of the right tooth plate 33. One end of the sliding seat 36 passes through the outside of the support portion 220 and is fixed with an upper driving protrusion 37. In a natural state, the bottom surface of the upper driving protrusion 37 is lower than the top surface of the lower driving protrusion 14. The surface of the sliding seat 36 is provided with a spring 38, and under the action of the spring 38, the upper driving protrusion 37 slides in a direction away from the support portion 220 in a natural state; The support plate 12 is provided with a placement position 120, a liquid injection position 121, a packaging position 122 and a transfer position 123 on its four sides; The front of the processing chamber 1 is provided with an operating rubber sleeve 15 at a position corresponding to the placement position 120. The arm can be extended into the interior of the processing chamber 1 through the operating rubber sleeve 15, and the empty battery cell can be placed on the limit seat 211 by operating the rubber sleeve 15. The front of the processing chamber 1 is provided with a liquid injection mechanism 16 at a position corresponding to the liquid injection position 121. The front of the processing chamber 1 is provided with a packaging mechanism 17 at a position corresponding to the packaging position 122. The collecting box 4 is placed on the processing chamber 1 at a position corresponding to the transfer position 123. like Figure 3As shown, the collection box 4 is inclined to be placed on the side wall of the processing bin 1. After the collection box 4 in the inclined state collects the packaged core package battery, the collected core package battery can slide towards the low end of the collection box 4. In this way, the collected core package battery can be arranged in order and compactly. The packaged core package battery does not need to be taken out after each packaging. The subsequent empty core package battery can be placed and injected with liquid. Only the collection box 4 needs to be taken out and replaced regularly. The tooth plate 214 is provided with a guide plate 215 at one end away from the transmission rope 34. The surface of the guide plate 215 is sleeved with a supporting spring 216. One end of the supporting spring 216 is fixed to the surface of the guide plate 215, and the other end is fixed to the surface of the tooth plate 214. The setting of the guide plate 215 can ensure the stability of the sliding state of the tooth plate 214, and also meet the synchronous driving of the plurality of driving wheels 213, so as to realize the synchronous rotation of the limiting seat 211. As shown, Figure 4 When liquid injection is needed, the empty core package to be injected is placed in the limiting seat 211 on the placement position 120. After the plurality of empty core battery packages on the single connecting seat 23 are placed in position in turn, the rotating motor 11 rotates clockwise at this time. The output end drives the connecting disc 24 to rotate synchronously. The empty core battery package after placement is completed is rotated to the next station and stopped. At this time, the liquid injection mechanism 16 on the liquid injection position 121 injects the gel electrolyte into the empty core battery package. After the injection is completed, the rotating motor 11 continues to rotate, so that the core package battery after liquid injection moves below the packaging mechanism 17. At this time, the core package battery after liquid injection is packaged by the action of the packaging mechanism 17. Then the rotating motor 11 further rotates, so that the packaged core package battery rotates at the position of the transfer position 123. When the connecting seat 23 driven by the rotating motor 11 is about to rotate to the position of the transfer position 123, the upper driving protrusion 37 on the supporting part 220 will be in contact with the lower driving protrusion 14 on the side, and the upper driving protrusion 37 subjected to the contact will drive the sliding seat 36 to slide upwards. The sliding seat 36 slides upwards, which drives the right side tooth plate 33 on one side to slide. At this time, the left side tooth plate 32 is driven by the transmission wheel 31 to move downwards synchronously. The left side tooth plate 32 in the downward movement state drives the tooth plate 214 to slide through the transmission rope 34. The tooth plate 214 in the sliding state synchronously rotates the plurality of driving wheels 213 meshing with one side. The driving wheels 213 mesh with the driven wheels 212 on one side. The driven wheels 212 driven by the meshing drive the rotating rods 210 on the driven wheels 212 to rotate synchronously. The limiting seat 211 on the rotating rod 210 rotates from the state of closely contacting the side wall of the connecting seat 23 to the state of corresponding to the lower exposed groove 230. When the connecting seat 23 rotates toFigure 6 At this time, the upper driving protrusion 37 is moved to the highest point position by the resistance of the lower driving protrusion 14; In this state, the battery core package in the limiting seat 211 will fall to the inside of the corresponding collecting box 4 below through the exposing groove 230. Since the collecting box 4 is in an inclined state, the battery core packages collected in the collecting box 4 in this state will slide to one side, so as to promote the compactness between each other and improve the overall collecting effect; When the rotating motor 11 rotates again by 90 degrees, the lower driving protrusion 14 will contact the upper driving protrusion 37, and the upper driving protrusion 37 not subjected to the resistance will slide back under the action of the spring 38, so as to make the tooth plate 214 and the corresponding limiting seat 211 rotate back synchronously for the next insertion of the empty battery core package; Thus, it is not necessary to take out the battery core package after the limiting seat 211 is encapsulated, so as to improve the overall work efficiency.

[0023] The above embodiments are only used to illustrate the present application and not to limit the technical solutions described in the present application. Although the present application has been described in detail with reference to the above embodiments, the present application is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement of the present application without departing from the spirit and scope of the present application is covered in the scope of claims of the present application.
