Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery preparation, and specifically relates to a processing kit for the remaining base material of lithium evaporation. Background Art

[0002] As an important energy storage device widely used in fields such as portable electronic devices, electric vehicles, and energy storage systems at present, the performance of lithium-ion batteries is crucial for the service life and performance of devices. However, traditional lithium-ion batteries have problems such as capacity attenuation, short cycle life, and insufficient safety after long-term cyclic charge and discharge. These problems mainly stem from the performance limitations of the battery cathode material and the interface problems between the electrolyte and the electrode material. In traditional lithium-ion batteries, the cathode material is usually composed of compounds of lithium ions, such as lithium cobalt oxide (LCO), lithium nickel manganese cobalt oxide (NMC), etc. These materials are prone to structural changes during the charge and discharge process, resulting in battery capacity attenuation and cycle life decline. In addition, the interface problems between the electrolyte and the electrode material also limit the performance improvement of the battery. For example, the decomposition of the electrolyte, the formation of the solid electrolyte interface layer, etc. These problems will cause adverse effects such as increased internal resistance and reduced safety of the battery.

[0003] The lithium evaporation technology is introduced as a method to improve battery performance. By forming a thin film on the cathode of a lithium-ion battery, the above problems can be effectively solved. Lithium evaporation can improve the energy density, cycle life, and safety of the battery. With the popularization of the advantages of lithium evaporation technology, the current commercial lithium evaporation process basically follows the evaporation method of heating the lithium source in a vacuum in the reactor. The evaporation method refers to a high-speed continuous winding type vacuum lithium evaporation device and a method for realizing substrate lithium evaporation using the same proposed in a Chinese patent (publication number: CN107177820B), which clarifies the currently common evaporation method. For the further improved process of this method, first, the substrate of the lithium mixture is evaporated, and then the remaining substrate after evaporation is mixed with an alloy. After mixing with the alloy and cooling, it is pressed into a lithium ingot. In view of the inconvenience of complex operations in the vacuum state reactor for the current improved process of this step, targeted improvements are made.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0024] As a further solution of the present utility model: The material discharging assembly includes two electric telescopic rods fixed on the surface of the base. One ends of the two electric telescopic rods are jointly movably connected by a pin shaft to a transmission plate. The other end of the transmission plate is movably connected by a pin shaft to a transmission frame. The transmission frame is fitted and slides on both sides of the base.

[0032] In this solution, the bottomless crucible is heated by a heater to perform the evaporation coating process. After the evaporation coating is completed, an alloy is added to the remaining base material in the bottomless crucible and gradually mixed under the heating action. When the mixing is gradually completed, two electric telescopic rods and an electromagnetic lock of the discharging component are started. As the electric telescopic rod extends, one end of its transmission plate moves along with the movement of the electric telescopic rod, causing the transmission plate to lose the support for the transmission frame. The transmission frame moves under the pulling force of the tension spring and pushes the transverse partition out of the base. At this time, the base material and alloy mixture in the bottomless crucible fall into the forming chamber and are above the stamping die. Its heat is quickly cooled through the heat dissipation grooves on the surface of the forming chamber. At the same time, the electric telescopic rod shortens, and the discharging component resets. The transverse partition closes the top of the forming chamber. Then, the hydraulic rod jacks up the stamping die, causing the stamping die to slide from the base into the forming chamber and cooperate with the transverse partition to extrude and form it in the forming chamber. This method can realize the automatic recovery and treatment of the remaining materials after evaporation coating, and can achieve highly automated treatment without opening in a vacuum reactor, which is convenient for the recycling and reuse of materials.

[0033] When the electromagnetic lock is started, its electromagnet adsorbs the counterweight block, causing the limiting groove at the bottom of the sliding pin to slide out. When the electromagnetic lock moves a certain distance with the transmission rack and then loses power, at this time, the limiting groove at the bottom of the sliding pin slides on the surface of the push rod. At this time, as the material discharging component moves independently with the transverse partition for opening and closing, when the material discharging component resets, under the action of the gravity of the counterweight block, the limiting groove at the bottom of its sliding pin is reinserted into the card slot. When stamping and forming, as the transmission rack of the material discharging component moves, under the action of the sliding pin, the card slot and the limiting groove limit and drive the push rod to move synchronously, so that the push rod pushes the forming chamber out of the base until the base material stamped and formed in the forming chamber drops and can reset under the action of the tension spring. This method can realize automatic material discharging operation, and the overall operation of associating with the material discharging component and interrupting the associated movement are coordinated with each other.

Detailed implementation mode

[0045] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0046] As Figures 1 to 8 shown, a device for processing the remaining substrate of lithium evaporation plating includes:

[0047] Base 1;

[0048] Bottomless crucible 2;

[0049] The bottomless crucible 2 is fixedly connected to the upper surface of the base, and a heater 17 for heating the internal substrate is wound inside the bottomless crucible 2;

[0050] Transverse partition plate 4;

[0051] The transverse partition plate 4 penetrates and slides on the upper surface of the inner wall of the base 1, and the upper surface of the transverse partition plate 4 is hermetically attached to the lower surface of the bottomless crucible 2;

[0052] Blanking assembly 6;

[0053] The blanking assembly 6 is installed on one side of the base 1 and is used to control the horizontal reciprocating movement of the transverse partition plate 4;

[0054] Forming chamber 5;

[0055] The forming chamber 5 penetrates and slides on one side of the base 1, and both the upper surface and the lower surface of the forming chamber 5 are through-shaped;

[0056] Stamping moving die 13;

[0057] The stamping moving die 13 is arranged below the forming chamber 5, and the surface of the stamping moving die 13 is fitted with the inner wall of the forming chamber 5;

[0058] Hydraulic rod 12;

[0059] The top end of the hydraulic rod 12 is fixedly connected to the upper surface of the inner wall of the stamping moving die 13 and is used to control the vertical linear movement of the stamping moving die 13;

[0060] Two push rods 9;

[0061] One end of the push rod 9 is fixedly connected to one side of the molding chamber 5, and the push rod 9 penetrates and slides on the surface of the base 1;

[0062] Electromagnetic lock 7;

[0063] The electromagnetic lock 7 is installed on the surface of the unloading component 6 and is used to control the synchronous and / or asynchronous movement of the push rod 9 and the unloading component 6.

[0064] The whole device is installed on one side of the cavity baffle of the reactor through the baffle mounting flange 18. Then, the heater 17 is started to heat the material in the bottomless crucible 2 to realize the evaporation coating process. After the evaporation coating is completed, the remaining base material and alloy are gradually mixed in the bottomless crucible 2, and the heating effect is used to promote the mixing process. Then, the two electric telescopic rods 61 and the electromagnetic lock 7 of the unloading component 6 are started. When the electromagnetic lock 7 is started, the limiting groove 75 at the bottom of the sliding pin 71 slides out by adsorbing the counterweight block 73. As the transmission frame 63 moves, the electromagnetic lock 7 is powered off, and the limiting groove 75 at the bottom of the sliding pin 71 slides on the surface of the push rod 9, thereby releasing the support of the transmission plate 62 on the transmission frame 63. The transmission frame 63 moves under the pulling force of the tension spring 64, pushing the diaphragm 4 out of the base 1, so that the mixture falls into the molding chamber 5. The heat dissipation grooves 15 on the surface of the molding chamber 5 quickly cool down the mixture. At the same time, the electric telescopic rod 61 shortens, the unloading component 6 resets, and the diaphragm 4 closes the top of the molding chamber 5. Subsequently, the hydraulic rod 12 jacks up the stamping die, so that the die slides from the base 1 into the molding chamber 5 and cooperates with the diaphragm 4 to extrude and form the mixture. Finally, as the transmission frame 63 of the unloading component 6 moves, under the action of the sliding pin 71, the push rod 9 pushes the molding chamber 5 out of the base 1 until the stamped base material in the molding chamber 5 drops, completing the entire process flow.

[0065] This solution realizes the automatic recycling of the remaining materials after the evaporation coating process. Through the coordinated action of devices such as the electric telescopic rod 61 and the electromagnetic lock 7, the remaining base material and alloy are mixed and stamped, reducing resource waste and manual operation, improving production efficiency and product quality, while simplifying the operation process, reducing production costs, and having significant economic and environmental benefits.

[0066] Specifically, as Figure 1 shown, a heat preservation layer 3 is arranged on the surface of the bottomless crucible 2, and a baffle mounting flange 18 for closed installation is arranged on the upper surface of the heat preservation layer 3.

[0067] The presence of the heat insulation layer 3 can effectively reduce heat dissipation, ensure uniform heating of the material in the bottomless crucible 2 by the heater 17, and thus guarantee the smooth progress of the evaporation coating process. The application of the heat insulation layer 3 makes the entire technological process more reliable and efficient, providing an important guarantee for the improvement of product quality and the increase of production efficiency.

[0068] Specifically, as Figure 5 shown, the material discharging assembly 6 includes two electric telescopic rods 61 fixed on the surface of the base 1. One ends of the two electric telescopic rods 61 are jointly movably connected to a transmission plate 62 through a pin shaft. The other end of the transmission plate 62 is movably connected to a transmission frame 63 through a pin shaft. The transmission frame 63 is fitted and slidably arranged on both sides of the base 1. Two tension springs 64 are fixed on the surface of the transmission frame 63, and the other ends of the tension springs 64 are fixedly connected to the surface of the base 1.

[0069] Through the cooperation with the electric telescopic rod 61, the movement of the material discharging assembly 6 is realized. The transmission plate 62 moves when the electric telescopic rod 61 extends, and then pushes the transmission frame 63 to move, ultimately causing the cross partition plate 4 to slide out of the base 1 and realizing the blanking process of the mixture.

[0070] The tension springs 64 ensure the stable movement and position fixation of components such as the transmission plate 62 and the transmission frame 63 by providing restoring force and supporting force. When the material discharging assembly 6 is reset, the tension springs 64 can quickly restore each component to the initial state, ensuring the continuity and stability of the entire technological process. In addition, the tension springs 64 can also apply a restoring force to the transmission plate 62 and the transmission frame 63 to keep them tightly connected during the working process, avoiding loosening or deviation.

[0071] Specifically, as Figure 2 and Figure 4 shown, the bottom surface of the base 1 is fixedly connected with a bottom support frame 11. A tension plate 14 for maintaining the shape is fixedly connected to the surface of the bottom support frame 11. A plurality of reinforcing rib plates 8 are arranged on the inner wall and the bottom surface of the bottom support frame 11.

[0072] The tension plate 14 can provide structural support force for the bottom support frame 11, so that when the bottom support frame 11 bears the reaction force of the support hydraulic rod 12, its deformation force can be converted into the pulling force on the tension plate 14, improving the structural strength of the bottom support frame 11. At the same time, with the cooperation of the reinforcing rib plates 8, the bottom of the bottom support frame 11 will not be deformed.

[0073] Specifically, as Figure 8 shown, the electromagnetic lock 7 includes a clamping frame 72 fixed on the upper surface of the transmission frame 63, and also includes a sliding pin 71 slidably penetrating through the upper surface of the transmission frame 63. A counterweight block 73 is fixedly connected to the upper surface of the sliding pin 71. A limiting groove 75 is opened at the bottom end of the sliding pin 71. An electromagnet 74 for adsorbing the counterweight block 73 is fixedly connected to the inner wall of the clamping frame 72.

[0074] The electromagnet 74 can be supported by the card holder 72. At the same time, the counterweight 73 can provide a downward pressure on the sliding pin 71, enabling the sliding pin 71 to move upward when the electromagnet 74 cooperates for adsorption.

[0075] The limiting groove 75 can cooperate with the card slot 10 to achieve horizontal limitation.

[0076] Specifically, as Figure 5 shown, a sealing ring 16 for maintaining sealing is fixedly connected to the inner wall of the base 1. The surface of the sealing ring 16 is attached to the surface of the transverse partition 4 to maintain the sealing of the horizontal movement of the transverse partition 4.

[0077] The sealing ring 16 can be attached to the surface of the transverse partition 4, enabling the transverse partition 4 to always maintain good sealing when sliding out and sliding in, avoiding leakage.

[0078] Specifically, as Figure 7 shown, a card slot 10 for cooperating with the limiting groove 75 to lock is provided at one end of the push rod 9, and a plurality of heat dissipation grooves 15 are provided on one side of the forming chamber 5.

[0079] The heat dissipation grooves 15 are on one side of the forming chamber 5, enabling the heat inside to be conducted to the forming chamber 5, which can assist in rapid cooling and accelerate the cooling time required for stamping.

[0080] Specifically, as Figure 2 shown, the bottom end of the hydraulic rod 12 is fixedly connected to the inner wall of the bottom support 11.

[0081] Specifically, as Figure 6 shown, two limiting side plates 19 are fixedly connected to the surface of the base 1, and the two limiting side plates 19 are respectively attached to both sides of the transmission frame 63.

[0082] The limiting side plates 19 can limit the transmission frame 63, keeping the transmission frame 63 sliding in the groove on the surface of the base 1 without slipping off and maintaining the stability of the movement.

[0083] Working principle:

[0084] When this solution is in use, it is integrally installed on one side of the cavity baffle of the reactor through the baffle mounting flange 18. Then, the heater 17 heats the inside of the bottomless crucible 2 for evaporation coating. After the evaporation coating is completed, an alloy is added to the remaining base material in the bottomless crucible 2 and gradually mixed under the action of heating. When the mixing is gradually completed, the two electric telescopic rods 61 and the electromagnetic lock 7 of the material discharging assembly 6 are started. As the electric telescopic rod 61 extends, one end of its transmission plate 62 moves along with the movement of the electric telescopic rod 61. When one end of the transmission plate 62 moves, the other end also moves under the action of the transmission frame 63. When the electromagnetic lock 7 is started, its electromagnet 74 adsorbs the counterweight 73, so that the limiting groove 75 at the bottom of its sliding pin 71 slides out. When the electromagnetic lock 7 moves a certain distance along with the transmission frame 63 and then powers off, at this time, the limiting groove 75 at the bottom of the sliding pin 71 slides on the surface of the push rod 9. At this time, the supporting distance of the transmission plate 62 to the transmission frame 63 changes. The transmission frame 63 moves under the pulling force of the tension spring 64 and pushes the transverse partition 4 out of the base 1. As the transverse partition 4 releases the closed state of the bottom of the bottomless crucible 2, the base material and alloy mixture in the bottomless crucible 2 fall into the forming chamber 5 and are above the stamping die. Its heat quickly cools down through the heat dissipation grooves 15 on the surface of the forming chamber 5. At the same time, the electric telescopic rod 61 shortens and the material discharging assembly 6 resets. The transverse partition 4 closes the top of the forming chamber 5. When the material discharging assembly 6 resets, under the gravity of the counterweight 73, the limiting groove 75 at the bottom of its sliding pin 71 is reinserted into the clamping groove 10. Then, the hydraulic rod 12 jacks up the stamping die, so that the stamping die slides from the base 1 into the forming chamber 5 and cooperates with the transverse partition 4 to extrude and form it in the forming chamber 5. When stamping and forming, as the transmission frame 63 of the material discharging assembly 6 moves, under the action of the sliding pin 71, the clamping groove 10 and the limiting groove 75 are limited to drive the push rod 9 to move synchronously, so that the push rod 9 pushes the forming chamber 5 out of the base 1 until the base material stamped and formed in the forming chamber 5 drops and then resets under the action of the tension spring 64.
