Description

Technical Field

[0001] The invention relates to the technical field of lithium ion battery formation, in particular to a lithium ion green battery core liquid injection formation process. Background Art

[0002] Lithium-ion batteries have the characteristics of high discharge voltage, high energy density and low self-discharge. There are two main ways to inject lithium-ion green batteries: one is direct injection through the injection hole, and the other is to place the battery in the electrolyte and let the electrolyte penetrate into the battery. The injection method through the injection hole can be divided into single injection and multiple injection according to the injection amount. The measures to promote infiltration of the several injection methods are different. Among them, the single injection method promotes the infiltration of the electrolyte in the battery cell by repeated pumping and pressing, while the multiple injection method promotes the infiltration of the electrolyte in the battery cell by pressurizing.

[0003] Cell injection and formation generally refers to the initial injection of electrolyte into the battery after a single cell is placed in a casing (hard shell) or after the coating (soft package) is completed but before it is completely sealed. This process allows the electrode to be fully immersed in the electrolyte within a specific process and temperature range. After this immersion, the battery undergoes the first charge and discharge, allowing the electrode material and electrolyte to chemically react at the solid-liquid interface, forming a passivation layer covering the surface of the electrode material. This passivation layer has the characteristics of a solid electrolyte: it is an electronic insulator but an excellent conductor of lithium ions. Li ions can freely embed and detach through this passivation layer, so this passivation film is called a "solid electrolyte interface film," or SEI film for short. This process requires the use of a formation device.

[0004] There are many types of such formation methods on the market today, which can basically meet people's usage needs, but there are still certain shortcomings. During the use of existing such formation methods, workers need to manually place the injected batteries into the device and use the charging and discharging electrodes of the device to charge and discharge the batteries with a small current. After the batteries are placed in the charging and discharging frame, the workers need to manually buckle the operation. Due to the influence of the weight and volume of multiple batteries, the operation is relatively laborious, the workers' work intensity is high, and it is difficult to improve the efficiency of the formation operation of the device. Summary of the Invention

[0005] The object of the present invention is to provide a lithium-ion green battery cell injection and formation process to solve the problem of high workload of workers during use of the device proposed in the above background technology.

[0009] S2: The stepper motor drives the guide seat lifting drive structure to work. The linear rack pushes the trapezoidal guide seat to move left. During the leftward movement of the trapezoidal guide seat, the trapezoidal guide seat will lift the lower right-angle tooling through the setting of the U-shaped positioning frame and the roller body, that is, the battery supported by the main battery bracket moves upward;

[0010] S3: The main battery bracket and the auxiliary battery bracket are wrapped around the battery. At this time, the battery undergoes the first charge and discharge, i.e., the formation treatment. The main battery bracket is heated by a ceramic heating plate, so that the electrode material and the electrolyte react chemically at the solid-liquid interface, thereby forming a passivation layer covering the surface of the electrode material.

[0011] S4: After the battery is charged and discharged, the stepper motor works in the reverse direction, that is, the lower right-angle fixture and other components move downward until the lower right-angle fixture and the auxiliary battery bracket are separated, and the battery can be taken out.

[0012] The cam is fixed on the outer wall of the lower frame, and the upper and lower frames are fixed with the upper and lower frames respectively.

[0013] The sliding guide unit includes a connecting seat installed on one side of the bottom end of the lower right-angle tooling, a U-shaped positioning frame is fixed to the bottom end of the connecting seat, a roller body is rotatably installed inside the U-shaped positioning frame, the roller body contacts the inclined surface of the trapezoidal guide seat, and a control panel is installed on the outer wall of one side of the frame.

[0014] Preferably, a plurality of sets of vertical guide rails are fixed on both side outer walls of the frame, a sliding sleeve is slidably mounted on one end of the surface of the vertical guide rail, and the surface of the sliding sleeve is fixedly connected to the back surface of the lower right-angle tooling.

[0015] Preferably, a plurality of groups of ceramic heating plates are installed on the outer wall of one side of the lower right-angle tooling.

[0016] Preferably, a plurality of groups of auxiliary rotation support units are provided on the inner wall of the support frame, and the number of the auxiliary rotation support units is the same as the number of the guide seat lifting drive structures.

[0018] Preferably, the auxiliary rotation support unit includes an auxiliary rotating shaft rotatably mounted on the inner wall of the support frame, and a driven sprocket is fixed to one end of the surface of the auxiliary rotating shaft.

[0019] Preferably, the guide seat lifting drive structure includes a ball bearing seat fixed on the inner wall of the support frame, a driving shaft is rotatably installed inside the ball bearing seat, a gear disc is fixed at one end of the surface of the driving shaft, a linear rack is installed inside the support frame below the gear disc through a transverse guide unit, the linear rack and the gear disc are engaged with each other, a worm is rotatably installed on the inner wall of the support frame, a stepper motor is installed on the outer wall of one side of the support frame, the output end of the stepper motor is fixedly connected to one end of the worm, a worm wheel is fixed at one end of the surface of the driving shaft, and the worm wheel and the worm are engaged with each other.

[0020] Preferably, the lateral guide unit includes a limiting track fixed on the inner wall of the support frame, and a slide is slidably mounted on one end of the surface of the limiting track, and the top end of the slide is fixedly connected to the bottom end of the linear rack.

[0021] Preferably, the chain power transmission mechanism includes a driving sprocket fixed on one end of the worm surface, and a chain body is installed on the outer surface of the driving sprocket. The chain body is used to drive the remaining guide seat lifting drive structure, and the chain body is a straight roller chain.

[0022] Compared with the prior art, the present invention has the following beneficial effects: the green lithium-ion battery cell liquid injection and formation process uses a mechanical structure to replace manual pushing of the battery for subsequent charging steps, which can effectively reduce the workload of workers and improve the operating efficiency of the device. At the same time, it also avoids the occurrence of time differences during the formation process of different groups of batteries, ensuring that the charging and discharging time of the same batch of batteries is consistent;

[0023] (1) By setting up a structure that cooperates with each other such as a linear rack and a stepper motor, and then turning on the stepper motor through the control panel, the stepper motor drives the guide seat lifting drive structure to work, so that the gear disc can drive the linear rack, the push column and the trapezoidal guide seat to move horizontally. During the left movement of the trapezoidal guide seat, the trapezoidal guide seat will lift the lower right-angle tooling through the setting of the U-shaped positioning frame and the roller body, that is, the battery supported by the main battery bracket moves upward until the battery electrodes contact the positive and negative electrode sheets. At this time, the main battery bracket and the auxiliary battery bracket are wrapped around the battery. At this time, the battery is charged and discharged for the first time, that is, the formation treatment, and the ceramic heating plate provides the battery with a suitable charge and discharge temperature. In this process, no manual operation is required by the staff. The mechanical structure replaces the manual operation, which can effectively reduce the work intensity of the staff;

[0024] (2) By providing a structure that cooperates with each other such as a vertical guide rail and an auxiliary rotation support unit, the roller body can roll on the inclined surface of the trapezoidal guide seat during the lifting and lowering of components such as the lower right-angle tooling, and the vertical guide rail and the slide are used to improve the lifting and lowering stability of the lower right-angle tooling, making the device more stable and reliable during operation;

[0025] (3) By setting up a structure that cooperates with each other such as a chain power transmission mechanism and a linear rack, the worm will drive the linear racks and guide seat lifting drive structures of other groups through the chain power transmission mechanism to work together, that is, the worm drives the active sprocket and the chain body to rotate, and then the chain body drives the worms of the remaining groups to rotate. In this process, the auxiliary shaft rotates together with the driven sprocket, so that the other main battery brackets and the upper right-angle tooling on the device can charge, discharge and form the battery together. The staff only needs to put the battery in and take it out, which can effectively improve the operating efficiency of the device. At the same time, it also avoids the occurrence of time difference when different groups of batteries are formed, that is, the charging and discharging time of the batteries of the same batch is consistent.

DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] Embodiment 1, by Figures 1 to 8 Given,

[0037] A green lithium-ion battery cell liquid injection and formation process comprises the following steps:

[0038] S1: Place multiple groups of batteries to be charged and discharged for the first time in the arc-shaped inner groove of the main battery bracket of the liquid injection formation device.

[0039] S2: The stepper motor drives the guide seat lifting drive structure to work. The linear rack pushes the trapezoidal guide seat to move left. During the leftward movement of the trapezoidal guide seat, the trapezoidal guide seat will lift the lower right-angle tooling through the setting of the U-shaped positioning frame and the roller body, that is, the battery supported by the main battery bracket moves upward;

[0040] S3: The main battery bracket and the auxiliary battery bracket are wrapped around the battery. At this time, the battery undergoes the first charge and discharge, i.e., the formation treatment. The main battery bracket is heated by a ceramic heating plate, so that the electrode material and the electrolyte react chemically at the solid-liquid interface, thereby forming a passivation layer covering the surface of the electrode material.

[0041] S4: After the battery is charged and discharged, the stepper motor works in the reverse direction, that is, the lower right-angle fixture and other components move downward until the lower right-angle fixture and the auxiliary battery bracket are separated, and the battery can be taken out.

[0042] The liquid injection and formation device includes a frame 1. Lower right-angle fixtures 3 are slidably mounted on the outer walls of both sides of the frame 1. A main battery bracket 4 is fixed to the inner wall of the lower right-angle fixture 3. The surface of the main battery bracket 4 is provided with evenly spaced arc-shaped inner grooves. An upper right-angle fixture 5 is fixed to the outer wall of the frame 1 above the lower right-angle fixture 3. A secondary battery bracket 502 is fixed to the inner wall of the upper right-angle fixture 5. The structure of the secondary battery bracket 502 is the same as that of the main battery bracket 4. Workers place multiple groups of batteries to be charged and discharged for the first time in the arc-shaped inner grooves of the main battery bracket 4.

[0043] The top of the upper right-angle tooling 5 is equipped with positive and negative electrode sheets 501, and the outer wall of one side of the lower right-angle tooling 3 is equipped with multiple sets of ceramic heating sheets 301. The ceramic heating sheets 301 are used to heat the main battery bracket 4 to provide a suitable charging and discharging environment for the battery;

[0044] A support frame 6 is fixed to the outer walls of both sides of the frame 1. A lifting drive assembly for driving the lower right-angle tooling 3 to rise and fall is provided inside the support frame 6. The lifting drive assembly includes multiple sets of guide seat lifting drive structures 15 and a chain power transmission mechanism 16. The guide seat lifting drive structure 15 includes a ball bearing seat 1505 fixed to the inner wall of the support frame 6. A driving shaft 1502 is rotatably installed inside the ball bearing seat 1505. The ball bearing seat 1505 improves the rotational stability of the driving shaft 1502 and the worm gear 1503.

[0045] A toothed disc 1504 is fixed to one end of the surface of the driving shaft 1502. A linear rack 12 is installed inside the support frame 6 below the toothed disc 1504 via a transverse guide unit 11. The linear rack 12 and the toothed disc 1504 are meshed with each other. A worm 1501 is rotatably mounted on the inner wall of the support frame 6. A stepper motor 13 is mounted on the outer wall of one side of the support frame 6. When the stepper motor 13 is turned on through the control panel 101, the stepper motor 13 drives the guide seat lifting drive structure 15 to operate.

[0046] The output end of the stepper motor 13 is fixedly connected to one end of the worm 1501. A worm wheel 1503 is fixed to one end of the surface of the driving shaft 1502. The worm wheel 1503 and the worm 1501 engage with each other. The stepper motor 13 drives the worm 1501, the worm wheel 1503, and the driving shaft 1502 to rotate.

[0047] Multiple groups of tappets 1401 are slidably mounted on the outer wall of one side of the support frame 6. The number of tappets 1401 is the same as that of the guide seat lifting drive structure 15. The multiple groups of tappets 1401 have a trapezoidal guide seat 14 fixed at one end.

[0048] Since the toothed disc 1504 and the linear rack 12 are meshed with each other, the toothed disc 1504 can drive the linear rack 12 to move horizontally, and then the linear rack 12 pushes the trapezoidal guide seat 14 to move leftward;

[0049] A sliding guide unit is provided at the bottom end of the lower right-angle tooling 3. The sliding guide unit includes a connecting seat 7 installed on one side of the bottom end of the lower right-angle tooling 3. A U-shaped positioning frame 8 is fixed to the bottom end of the connecting seat 7. A roller body 9 is rotatably installed inside the U-shaped positioning frame 8. The U-shaped positioning frame 8 is made of an aluminum alloy component. The roller body 9 is a PU roller. During the lifting process of the lower right-angle tooling 3 and other components, the roller body 9 can roll on the inclined surface of the trapezoidal guide seat 14;

[0050] During the leftward movement of the trapezoidal guide seat 14, the trapezoidal guide seat 14 will lift the lower right-angle tooling 3 through the arrangement of the U-shaped positioning frame 8 and the roller body 9, that is, the battery supported by the main battery bracket 4 moves upward until the battery electrodes contact the positive and negative electrode sheets 501;

[0051] The main battery bracket 4 and the auxiliary battery bracket 502 are wrapped around the battery. At this time, the battery undergoes the first charge and discharge, i.e., the formation process, which causes the electrode material and the electrolyte to react chemically at the solid-liquid interface, thereby forming a passivation layer covering the surface of the electrode material. Manual operation by the staff is eliminated, and the mechanical structure replaces manual operation, which can effectively reduce the workload of the staff.

[0052] A control panel 101 is mounted on the outer wall of one side of the frame 1 . The output end of the single chip microcomputer inside the control panel 101 is electrically connected to the ceramic heating plate 301 and the input end of the stepping motor 13 .

[0053] Example 2, based on Example 1, Figure 1 、 Figure 2 、 Figure 3 and Figure 4The chain power transmission mechanism 16 includes a driving sprocket 1601 fixed to one end of the surface of the worm 1501. The outer surface of the driving sprocket 1601 is mounted with a chain body 1602. The chain body 1602 is used to drive the remaining guide seat lifting drive structure 15. The chain body 1602 is a straight plate roller chain. When the worm 1501 rotates, the worm 1501 will drive the other groups of linear racks 12 and the guide seat lifting drive structure 15 to work together through the chain power transmission mechanism 16.

[0054] The worm 1501 drives the active sprocket 1601 and the chain body 1602 to rotate, and the chain body 1602 then drives the remaining groups of worms 1501 to rotate. During this process, the auxiliary shaft 1001 rotates together with the driven sprocket 1002, so that the other main battery brackets 4 and the upper right-angle tooling 5 on the device can charge, discharge and form the batteries together. The staff only needs to put the batteries in and take them out, which can effectively improve the operating efficiency of the device. At the same time, it also avoids the occurrence of time difference when different groups of batteries are formed, that is, the charging and discharging time of the batteries in the same batch is consistent.

[0055] Example 3, based on Example 1, Figure 1 and Figure 2 It is given that a plurality of sets of vertical guide rails 2 are fixed on the outer walls of both sides of the frame 1, and a sliding sleeve is slidably installed on one end of the surface of the vertical guide rail 2. The surface of the sliding sleeve is fixedly connected to the back of the lower right-angle tooling 3. The vertical guide rails 2 and the sliding sleeve are arranged to improve the lifting stability of the lower right-angle tooling 3, making the device more stable and reliable during operation.

[0056] A plurality of auxiliary rotation support units 10 are provided on the inner wall of the support frame 6. The number of the auxiliary rotation support units 10 is the same as the number of the guide seat lifting drive structure 15. The auxiliary rotation support unit 10 includes an auxiliary rotating shaft 1001 rotatably mounted on the inner wall of the support frame 6. A driven sprocket 1002 is fixed to one end of the surface of the auxiliary rotating shaft 1001.

[0057] The lateral guide unit 11 includes a limiting rail 1101 fixed on the inner wall of the support frame 6. A slide 1102 is slidably installed on one end of the surface of the limiting rail 1101. The top of the slide 1102 is fixedly connected to the bottom end of the linear rack 12. The linear rack 12 will drive the slide 1102 to slide on the limiting rail 1101, and the horizontal movement stability of the linear rack 12 is improved through the lateral guide unit 11.

[0058] When the embodiment of the present application is in use, the staff first places multiple groups of batteries to be charged and discharged for the first time in the arc-shaped inner groove of the main battery bracket 4, and then turns on the stepper motor 13 through the control panel 101. The stepper motor 13 drives the guide seat lifting drive structure 15 to work, that is, the stepper motor 13 drives the worm 1501, the worm wheel 1503, and the driving shaft 1502 to rotate, and the ball bearing seat 1505 improves the rotation stability of the driving shaft 1502 and the worm wheel 1503. Since the toothed disc 1504 and the linear rack 12 are engaged with each other, the toothed disc 1504 can drive the linear rack 12 to move horizontally, and then the linear rack 12 pushes the trapezoidal guide seat 14 to move left. In the process of the trapezoidal guide seat 14 moving left, the trapezoidal guide The seat 14 will lift the lower right-angle tooling 3 through the setting of the U-shaped positioning frame 8 and the roller body 9, that is, the battery supported by the main battery bracket 4 moves upward until the battery electrodes are in contact with the positive and negative electrode sheets 501. At this time, the main battery bracket 4 and the auxiliary battery bracket 502 are wrapped around the battery. At this time, the battery undergoes the first charge and discharge, that is, the formation treatment, and the main battery bracket 4 is heated by the ceramic heating plate 301 to provide a suitable charge and discharge environment for the battery, so that the electrode material and the electrolyte react chemically at the solid-liquid two-phase interface, thereby forming a passivation layer covering the surface of the electrode material. No manual operation is required by the staff in this process. The mechanical structure replaces the manual operation, which can effectively reduce the work intensity of the staff.
