[0035] Please refer to Figure 1 and Figure 3 The high-temperature formation cabinet 1 provided by the embodiments of the present application will be described.

[0036] The high-temperature formation cabinet 1 provided by the embodiments of the present application comprises a cabinet body 11, an air duct plate group 12 and a hot air assembly 13.

[0037] Referring to Figure 1 and Figure 3 , the inside of the cabinet body 11 is divided into the power supply compartment 111, the formation compartment 112 and the hot air compartment 113 arranged in sequence.

[0038] The cabinet body 11 is the main structure of the entire high-temperature formation cabinet 1, which divides the internal space into the power supply compartment 111, the formation compartment 112 and the hot air compartment 113 arranged in sequence.

[0039] The power supply compartment 111 is used to place the power supply equipment and the control module for providing power for the entire cabinet, and the touch panel of the control module is arranged on the outer wall of the power supply compartment 111. The power supply compartment 111 needs to ensure good heat dissipation and electrical safety performance, so a plurality of heat dissipation holes are formed on the side wall of the power supply compartment 111. The power supply compartment 111 is also provided with a side door which can be opened to overhaul the equipment in the power supply compartment 111.

[0040] The formation compartment 112 is the main area for high-temperature formation of the battery, and the hot air compartment 113 places the hot air assembly 13 to provide power and heat source for the entire hot air circulation.

[0041] Referring to Figure 3 and Figure 4 , the air duct plate group 12 divides the formation compartment 112 into the formation chamber 1126 and the air inlet duct 1127 in the formation compartment 112, the formation chamber 1126 is communicated with the hot air compartment 113 through the air return port 1122, one end of the air inlet duct 1127 is communicated with the air inlet port 1121, and the other end extends to the side of the formation chamber 1126 away from the air return port 1122. The air duct plate group 12 is installed in the formation compartment 112, which divides the formation chamber 1126 and the air inlet duct 1127 into two areas.

[0042] The formation chamber 1126 is a space for placing batteries for high-temperature formation. For example, when high-temperature formation is performed on lithium-ion batteries, multiple lithium-ion batteries can be arranged neatly in the formation chamber 1126. The formation chamber 1126 is in communication with the hot air bin 113 through the air return port 1122, so that the hot air can return to the hot air bin 113 after completing the heating of the batteries.

[0043] The function of the air inlet duct 1127 is to guide the hot air from the hot air bin 113 to the formation chamber 1126. For example, the air inlet duct 1127 can be a channel made of a metal plate or a plastic plate, and the inner surface is smooth to reduce the resistance of the hot air.

[0044] Referring to Figure 3 and Figure 4 , the hot air assembly includes a fluid driver 131 and a heater 132. The fluid driver 131 is arranged in the hot air bin 113, and is used to drive the airflow from the hot air bin 113 into the air inlet duct 1127, and from the formation chamber 1126 into the hot air bin 113 through the air return port 1122. The heater 132 is used to heat the airflow. The fluid driver 131 can be a fan or a blower, and the heater 132 can be a heating bag, an electric heating tube or a ceramic heater 132, and the heating power can be adjusted as needed. The heater 132 can be installed in the hot air bin 113 or near the air return port 1122 in the formation bin 112, as close to the fluid driver 131 as possible, so as to quickly send the heated hot air into the air inlet duct 1127.

[0045] In summary, the exhaust duct in the hot air bin 113 plays a crucial role in the fire extinguishing system of the high-temperature formation cabinet 1, which can timely remove smoke and harmful gases in emergency situations, and improve the safety and reliability of the equipment. The hot air bin 113 is also provided with a side door for the equipment in the hot air bin 113.

[0046] Based on the above structure, the high-temperature formation cabinet 1 of the embodiment of the application realizes the integration of high-temperature formation and control of the batteries by dividing the cabinet body 11 into three parts: the power supply bin 111, the formation bin 112 and the hot air bin 113. The structure is more compact. At the same time, the air duct plate set 12 is used to divide the formation bin 112 into the formation chamber 1126 and the air inlet duct 1127, which cooperates with the fluid driver 131 and the heater 132 to form a hot air circulation system. Only one fluid driver 131 is needed to realize the circulation of hot air, which reduces the cost of the equipment and improves the reliability and stability of the equipment.

[0047] Referring to Figure 3 and Figure 4The cabinet body 11 further comprises a first partition plate 114 and a second partition plate 115. The first partition plate 114 is located between the formation chamber 112 and the hot air chamber 113. The second partition plate 115 is located between the power supply chamber 111 and the formation chamber 112. The return air inlet 1122 is arranged on the second partition plate 115. The second partition plate 115 is further provided with an air inlet 1121 which communicates the air inlet channel 1127 with the hot air chamber 113. The air inlet 1121 is a passage through which the hot air enters the formation chamber 112. The return air inlet 1122 is a passage through which the hot air returns from the formation chamber 112 to the hot air chamber 113.

[0048] The first partition plate 114 is located between the formation chamber 112 and the hot air chamber 113, separating the two chambers. The first partition plate 114 can prevent the hot air in the hot air chamber 113 from directly spreading to other areas of the formation chamber 112, ensuring that the hot air can flow according to the predetermined air channel. In addition, the first partition plate 114 also provides support and fixation for the fluid driver 131 and the heater 132 installed in the hot air chamber 113. Specifically, the first partition plate 114 can be a plate with good thermal insulation performance, avoiding the high temperature in the formation chamber 112 from affecting the equipment in the hot air chamber 113.

[0049] The second partition plate 115 is located between the power supply chamber 111 and the formation chamber 112, separating the power supply equipment in the power supply chamber 111 from the battery and the hot air circulation system in the formation chamber 112, improving the safety and stability of the equipment. The second partition plate 115 is provided with an air inlet 1121 and a return air inlet 1122, allowing the hot air to circulate between the formation chamber 112 and the hot air chamber 113. The return air inlet 1122 can be one or more circular or rectangular openings, the size of which can be designed according to the flow and flow rate of the hot air. The design of the position and size of the air inlet 1121 and the return air inlet 1122 needs to consider the uniform distribution and circulation efficiency of the hot air, to ensure that the battery can be formed in a uniform high temperature environment.

[0050] Referring to Figure 3 and Figure 4 The air duct plate set 12 comprises a first air duct plate 121 and a second air duct plate 122 arranged in the formation chamber 112. One end of the first air duct plate 121 is vertically connected to one end of the second air duct plate 122. One end of the first air duct plate 121 is connected to the first partition plate 114. A first gap 11271 is formed between the first air duct plate 121 and the top wall of the formation chamber 112. The air inlet 1121 communicates with the first gap 11271. The second air duct plate 122 is parallel to the second partition plate 115. A second gap 11272 is formed between the second air duct plate 122 and the second partition plate 115. The air inlet channel 1127 comprises the first gap 11271 and the second gap 11272. The formation chamber 1126 is located on the side of the second air duct plate 122 away from the second gap 11272. The second air duct plate 122 is provided with a first ventilation hole 1221 which communicates the second gap 11272 and the formation chamber 1126.

[0051] That is, a first gap 11271 is formed between the first air duct plate 121 and the top wall of the formation bin 112, and a second gap 11272 is formed between the second air duct plate 122 and the second partition plate 115. The first gap 11271 and the second gap 11272 are connected to form an air inlet 1127. The air inlet 1121 is in communication with the first gap 11271, so that the hot air in the hot air bin 113 can enter the air inlet 1127. The second air duct plate 122 is provided with a first air hole 1221 in communication with the second gap 11272 and the formation chamber 1126, so as to ensure that the hot air can enter the formation chamber 1126 from the air inlet 1127. Specifically, the first air hole 1221 can be multiple, for example, 10, which are uniformly arranged on a section of the second air duct plate 122.

[0052] Based on the above structure, the fluid driver 131 in the hot air bin 113 drives the hot air to enter the first gap 11271 from the air inlet 1121, then pass through the second gap 11272, and then enter the formation chamber 1126 through the first air hole 1221 on the second air duct plate 122. The design of the air inlet 1127 ensures that the hot air can flow along the predetermined path, improves the efficiency and uniformity of the hot air circulation, and thus ensures that the battery can be subjected to uniform high temperature during the formation process.

[0053] Referring to Figure 3 and Figure 4 , the air duct plate set 12 further comprises an arc-shaped air deflector 123, which is arranged at the connection between the first gap 11271 and the second gap 11272. One end of the arc-shaped air deflector 123 is connected to the top wall of the formation bin 112, and the other end is connected to the second air duct plate 122, so as to guide the airflow from the first gap 11271 into the first air hole 1221.

[0054] The arc-shaped air deflector 123 is fixedly connected to the top wall of the formation bin 112 and the second air duct plate 122 by welding or bolt connection, so as to ensure that it will not be loose or displaced during the flow of hot air. The arc-shaped air deflector 123 is arranged at the connection between the first gap 11271 and the second gap 11272, and divides the second gap 11272 into an arc inside and an arc outside. The end of the first gap 11271 and the first air hole are located in the arc inside.

[0055] The arc-shaped air guide plate 123 can guide the air flow from the first gap 11271 into the first air vent 1221. During the hot air circulation process, after the hot air enters the first gap 11271 from the air inlet 1121, since the direction of the air flow is not perpendicular to the second air duct plate 122, an air guide device is needed to guide the air flow to smoothly enter the second gap 11272 and the first air vent 1221. The arc-shaped design of the arc-shaped air guide plate 123 can make the air flow change direction more smoothly, reducing the resistance and energy loss of the air flow. When the hot air comes out of the first gap 11271, the arc-shaped air guide plate 123 can smoothly guide the air flow to the first air vent 1221 on the second air duct plate 122, so that the hot air can quickly and uniformly enter the formation chamber 1126, improving the efficiency of hot air circulation and the formation effect. Such design can ensure that the battery can fully contact the hot air during the formation process, thereby achieving uniform high-temperature formation.

[0056] With reference to Figure 3 and Figure 4 The air duct plate set 12 further comprises a third air duct plate 124, which is arranged in the formation bin 112. The third air duct plate 124 is parallel to the first partition plate 114. One end of the third air duct plate 124 is connected to the first air duct plate 121, and the other end is connected to the bottom wall of the formation bin 112. The third air duct plate 124 and the first partition plate 114 form an air return duct 1128. The formation chamber 1126 is located on the side of the third air duct plate 124 away from the air return duct 1128. The third air duct plate 124 is provided with a second air vent 1241 that communicates the formation chamber 1126 and the air return duct 1128. The third air duct plate 124 and the first partition plate 114 form an air return duct 1128. Understandably, there is a gap between the third air duct plate 124 and the first partition plate 114, which is the air return duct 1128. In the hot air circulation system, the air return duct 1128 functions to guide the hot air from the formation chamber 1126 back to the hot air bin 113. The formation chamber 1126 is located on the side of the third air duct plate 124 away from the air return duct 1128. When the hot air completes heating the battery in the formation chamber 1126, it enters the air return duct 1128 through the second air vent 1241 on the third air duct plate 124. The second air vent 1241 can be a circular hole, and the number can be multiple, evenly distributed on the third air duct plate 124, to ensure that the hot air can uniformly enter the air return duct 1128 from the formation chamber 1126.

[0057] Based on the above structure, the hot air is driven by the fluid driver 131 from the hot air bin 113, enters the first gap 11271 through the air inlet 1121, then enters the second gap 11272 guided by the arc-shaped air deflector 123, and then enters the formation chamber 1126 through the first air hole 1221 on the second air duct plate 122. After heating the battery in the formation chamber 1126, the hot air enters the return air duct 1128 through the second air hole 1241 on the third air duct plate 124, and finally returns to the hot air bin 113, completing a complete hot air circulation. Such a design enables the hot air to circulate efficiently in the formation bin 112, ensuring that the battery can be uniformly heated during high-temperature formation, improving the formation effect and the working efficiency of the equipment.

[0058] With reference to Figure 3 and Figure 4 The heater 132 is arranged in the return air duct 1128. The return air duct 1128 is a channel for the hot air returning from the formation chamber 1126 to the hot air bin 113. By arranging the heater 132 here, the hot air that has passed through the formation chamber 1126 and whose temperature may have decreased can be reheated during the circulation of the hot air. In this way, it can be ensured that the temperature of the hot air can be maintained at a relatively high level before re-entering the air inlet 1127 and the formation chamber 1126, so as to ensure the high-temperature formation effect on the battery.

[0059] With reference to Figure 5 and Figure 6 One side of the formation bin 112 is provided with an access opening 1123, and the side of the formation bin 112 away from the access opening 1123 is provided with a maintenance opening 1124 and a cable opening 1125. The cabinet body 11 further comprises a cabinet door 116 for closing the access opening 1123, a maintenance door 117 for closing the maintenance opening 1124, and a baffle 118 for closing the cable opening 1125.

[0060] When performing the high-temperature formation operation of the battery, the operator can put the battery to be formed into the formation chamber 1126 through this opening, and take out the formed battery after the formation is completed.

[0061] The side of the formation bin 112 away from the access opening 1123 is provided with a maintenance opening 1124 and a cable opening 1125. When the equipment fails or needs to be maintained regularly, the maintenance personnel can enter the inside of the formation bin 112 through the maintenance opening 1124 to perform inspection and maintenance work.

[0062] The cable opening 1125 is used for passing various cables such as power supply lines, signal lines, etc. These cables are connected to the equipment in the formation bin 112 and the external power supply, control system, etc. The arrangement of the cable opening 1125 can make the arrangement of the cables more orderly and standardized, and also facilitate the replacement and maintenance of the cables when needed.

[0063] The cabinet door 116 can be made of metal or plastic material, with certain strength and sealing. The cabinet door 116 can be connected with the cabinet 11 by hinges or sliding rails, etc., to facilitate opening and closing. When the battery formation operation is performed, the cabinet door 116 is closed to prevent hot air leakage and ensure the temperature stability in the formation chamber 1126. At the same time, the cabinet door 116 can also play a certain safety protection role to prevent personnel from accidentally touching the equipment in the formation chamber 1126.

[0064] The maintenance door 117 is provided to close the maintenance port 1124. The maintenance door 117 is in a closed state in normal times to ensure the sealing and safety of the formation chamber 112. When maintenance work is needed, maintenance personnel can open the maintenance door 117 to enter the inside of the formation chamber 112.

[0065] The baffle 118 is used to close the cable port 1125. The baffle 118 can be a metal plate or a plastic plate, which is fixed on the cabinet 11 by bolts or buckles, etc. When the cable passes through the cable port 1125, the baffle 118 can close the cable port 1125.

[0066] Referring to Figure 5 and Figure 6 , the high-temperature formation cabinet 1 further comprises a fire-fighting pipeline 14 and a drainage pipeline 15. The fire-fighting pipeline 14 extends from the side of the formation chamber 112 away from the inlet and outlet port 1123 to the upper end of the formation chamber 1126, and the drainage pipeline 15 has one end located at the bottom wall of the formation chamber 1126 and the other end extending from the side of the formation chamber 112 away from the inlet and outlet port 1123.

[0067] The fire-fighting pipeline 14 extends from the side of the formation chamber 112 away from the inlet and outlet port 1123 to the upper end of the formation chamber 1126. The fire-fighting pipeline 14 enters the formation chamber 112 from the outside of the formation chamber 112 through a special hole in the wall of the formation chamber 112, and extends to the upper end of the formation chamber 1126. Such an arrangement can ensure that the fire-fighting medium can quickly and effectively cover the key areas of the formation chamber 1126 in the event of an emergency such as a fire. Understandably, the fire-fighting pipeline 14 is connected with a spray head in the formation chamber 112, which can spray when a fire occurs. The main role of the fire-fighting pipeline 14 is to provide fire extinguishing medium such as water, dry powder, carbon dioxide, etc. in the event of an emergency such as a fire in the high-temperature formation cabinet 1, to quickly extinguish the fire source and protect the equipment and personnel safety.

[0068] One end of the drain pipe 15 is connected to the bottom wall of the formation chamber 1126, usually in a sealed manner, to prevent water leakage. The other end extends outside the formation chamber 112 through the wall of the formation chamber 112, so as to drain the accumulated water in the formation chamber 1126. During the formation process, a small amount of water may be generated due to various reasons, such as battery leakage, condensation of moisture in the air, etc. The role of the drain pipe 15 is to timely drain these accumulated water from the formation chamber 1126, so as to maintain a dry environment in the formation chamber 1126 and ensure the formation quality of the battery and the normal operation of the equipment. At the same time, the drain pipe 15 can also drain the waste water after cleaning the formation chamber 1126, facilitating the maintenance and cleaning of the equipment.

[0069] With reference to Figure 3 and Figure 4 The formation chamber 112 is provided with a plurality of formation chambers 112, and each formation chamber 112 is arranged in a stacked manner from bottom to top. The air duct plate group 12 and the hot air assembly 13 correspond to each formation chamber 112 one by one.

[0070] The formation chamber 112 is provided with a plurality of formation chambers 112, and each formation chamber 112 is arranged in a stacked manner from bottom to top. For example, two formation chambers 112 can be provided, and the horizontal partition plate between each formation chamber 112 is separated upward and downward. This stacked arrangement can make full use of space and improve the integration and production efficiency of the equipment.

[0071] The air duct plate group 12 and the hot air assembly 13 correspond to each formation chamber 112 one by one. For each formation chamber 112, there is a set of independent air duct plate group 12. This set of air duct plate group 12 divides the formation chamber 1126, the air inlet duct 1127 and the air return duct 1128 in the formation chamber 112, to ensure that the hot air can circulate in the formation chamber 112. Similarly, each formation chamber 112 is equipped with an independent hot air assembly 13, so that the flow and temperature of the hot air can be independently controlled according to the actual needs of each formation chamber 112, to improve the precision and stability of the formation. For example, when forming different specifications of batteries, the parameters of the hot air assembly 13 of a certain formation chamber 112 can be adjusted to meet the specific formation requirements.

[0072] In summary, the stacked arrangement of the plurality of formation chambers 112, and the one-to-one correspondence of the air duct plate group 12 and the hot air assembly 13 to the formation chamber 112, enable the high-temperature formation cabinet 1 to simultaneously perform formation operation on different specifications of batteries, improving the flexibility and production efficiency of the equipment.

[0073] In addition, the hot air bin 113 is also provided with an exhaust duct for a fire smoke exhaust duct. The exhaust duct is used to timely exhaust smoke and harmful gas in the hot air bin 113 in the event of an emergency such as a fire. The exhaust duct is usually connected to an external fire smoke exhaust system, and when a fire signal is detected, the exhaust function is automatically started to rapidly exhaust the smoke and harmful gas in the hot air bin 113, thereby ensuring the safety of the equipment and personnel.

[0074] The high-temperature formation device also includes a power supply, a control module, a needle bed, a negative pressure module, and the high-temperature formation cabinet 1 described above. The power supply and the control module are arranged in the power supply bin 111, the needle bed is arranged in the formation chamber 1126, and the negative pressure module is arranged in the hot air bin 113. The negative pressure module is used to provide negative pressure to the battery liquid injection port in the needle bed.

[0075] The power supply is arranged in the power supply bin 111 to provide power support for the entire high-temperature formation device.

[0076] The control module is also arranged in the power supply bin 111 and is used to control and adjust various parts of the high-temperature formation device. The control module can receive signals from various sensors such as temperature sensors and pressure sensors, and control the power supply, the hot air assembly 13, and the negative pressure module according to pre-set programs and parameters. The control module can include a touch panel, buttons, and other structures installed on the outside of the power supply bin 111 for operation by an operator.

[0077] The needle bed is arranged in the formation chamber 1126 and is used to place and electrically connect the battery. The probes on the needle bed can contact the electrodes of the battery to perform charging, discharging, and testing operations on the battery.

[0078] The negative pressure module is arranged in the hot air bin 113 and is used to provide negative pressure to the battery liquid injection port in the needle bed. During the battery formation process, it is sometimes necessary to inject electrolyte into the battery. The negative pressure module can be connected to the battery liquid injection port on the needle bed through a pipeline to provide a certain negative pressure to help the electrolyte smoothly enter the battery.

[0079] During the operation of the high-temperature formation device, the power supply provides power to each part, and the control module controls the entire device. The battery on the needle bed is subjected to high-temperature formation in the formation chamber 1126, and the hot air assembly 13 provides the required high-temperature environment for the battery by circulating hot air. At the same time, the negative pressure module provides negative pressure to the battery liquid injection port as needed to ensure smooth injection of electrolyte. Each part cooperates to complete the high-temperature formation and liquid injection of the battery, improving the efficiency and quality of battery production.
