Technical Field

[0001] This invention relates to the field of battery production, specifically to a pressurized heating device. Background Technology

[0002] In the lithium battery production process, lithium battery modules need to be pressurized and heated. The traditional method is to place stacked lithium batteries on a fixture, apply pressure by pressing with the fixture, and then transport the lithium batteries and the fixture together into an oven for heating. The traditional pressurization and heating method has low efficiency. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a pressurized heating device, the detailed technical solution of which is as follows:

[0004] A pressurized heating device includes a mounting bracket and several pressurized heating chambers, wherein:

[0005] The mounting bracket has several receiving cavities;

[0006] Each pressurized heating box can be removably inserted into a receiving cavity. The pressurized heating box is equipped with a pressurizing mechanism and a heating mechanism. The pressurizing mechanism is used to compress the lithium battery module located in the pressurized heating box, and the heating mechanism is used to heat the lithium battery module.

[0007] This invention allows stacked lithium batteries to be placed directly into the housing, enabling automatic pressurization and heating of the lithium battery modules, thereby improving the pressurization and heating efficiency of the lithium battery modules.

[0008] In some embodiments, the pressurized heating chamber includes a chamber body and a flip cover. The chamber body is provided with a material inlet for picking up and putting in lithium battery modules. The flip cover is located at the material inlet. When the flip cover is flipped upward, the material inlet is opened. When the flip cover is flipped downward, the material inlet is closed.

[0009] By setting a flip-top cover, the pressurized heating chamber can be opened and closed, ensuring that the pressurized heating chamber remains closed during the processing.

[0010] In some embodiments, a flip-connecting assembly is provided on the housing at the upper edge of the feed inlet, and the upper end of the flip cover is connected to the flip-connecting assembly; a flip-drive assembly is provided on the mounting bracket, and the flip-drive assembly drives the flip-connecting member to rotate, thereby causing the flip cover to flip up and down.

[0011] The automatic opening and closing of the flip cover is achieved through the cooperation of the flip drive component and the flip connection component.

[0012] In some embodiments, a baffle is attached to the inner wall of the flip cover.

[0013] By setting a baffle on the inner wall of the flip cover, the inner wall of the flip cover is prevented from contacting the lithium battery module.

[0014] In some embodiments, the pressurizing mechanism includes a lifting drive mechanism and a pressure plate, wherein the lifting drive mechanism is connected to the top wall of the pressurizing heating box, and the pressure plate is connected to the drive end of the lifting drive mechanism, and the lifting drive mechanism drives the pressure plate to press down to compress the lithium battery module.

[0015] A simple pressurizing mechanism is provided, which drives the pressure plate to press down through a lifting drive mechanism to squeeze the lithium battery module.

[0016] In some embodiments, the pressurized heating chamber is provided with multiple pressurized heating stations, each pressurized heating station can hold a set of lithium battery modules, and each pressurized heating station is provided with a set of pressurizing mechanism and a set of heating mechanism.

[0017] By setting up multiple pressurization and heating stations inside the pressurization and heating chamber, the pressurization and heating chamber of the present invention can simultaneously perform pressurization and heating treatment on multiple sets of lithium battery modules, which greatly improves the processing efficiency.

[0018] In some embodiments, each heating mechanism includes a heating lamp tube disposed on the side of the corresponding pressurized heating station.

[0019] By using heating lamps placed on the side of the pressurized heating station to heat the battery module located at that pressurized heating station at close range, the heating effect is improved.

[0020] In some embodiments, the pressurized heating box is provided with a power socket; the pressurized heating device also includes a plurality of power supply mechanisms corresponding one-to-one with a plurality of accommodating cavities. The power supply mechanism includes a power plug drive mechanism and a power plug. The power plug drive mechanism is connected to the mounting bracket, and the power plug is connected to the drive end of the power plug drive mechanism and matches the power socket. When the power plug drive mechanism drives the power plug to move toward the power socket, the power plug engages with the power socket; when the power plug drive mechanism drives the power plug to move away from the power socket, the power plug disengages from the power socket.

[0021] By installing a power socket on the pressure heating box and a power plug driven by a power plug drive mechanism in each accommodating cavity, when the pressure heating box is inserted into the accommodating cavity, the power plug can quickly connect with the power socket on the pressure heating box to supply power to the pressure heating box. When the pressure heating box is removed from the accommodating cavity, the power plug can quickly disconnect from the power socket on the pressure heating box.

[0022] In some embodiments, the pressurized heating box is provided with a gas source socket; the pressurized heating device also includes a plurality of gas supply mechanisms corresponding one-to-one with a plurality of accommodating cavities. The gas supply mechanism includes a gas source plug drive mechanism and a gas source plug. The gas source plug drive mechanism is connected to the mounting bracket, and the gas source plug is connected to the drive end of the gas source plug drive mechanism and matches the gas source socket. When the gas source plug drive mechanism drives the gas source plug to move toward the gas source socket, the gas source plug engages with the gas source socket; when the gas source plug drive mechanism drives the gas source plug to move away from the gas source socket, the gas source plug disengages from the gas source socket.

[0023] By setting a gas source socket on the pressurized heating box and setting a gas source plug driven by a gas source plug drive mechanism at each accommodating cavity, when the pressurized heating box is inserted into the accommodating cavity, the gas source plug can quickly connect with the gas source socket on the pressurized heating box to supply gas to the pressurized heating box, and when the pressurized heating box is removed from the accommodating cavity, the gas source plug can quickly disconnect from the gas source socket on the pressurized heating box.

[0024] In some embodiments, the gas supply mechanism further includes a position adjustment component disposed on a mounting bracket, and a gas source plug drive mechanism connected to the position adjustment component. The position adjustment component is used to adjust the position of the gas source plug so that the gas source plug is aligned with the gas source socket.

[0025] By setting a position adjustment component, the position of the gas source plug can be adjusted so that the gas source plug is aligned with the gas source socket.

[0026] In some embodiments, the position adjustment component includes an X-axis translation mechanism and a Y-axis translation mechanism, wherein: the X-axis translation mechanism is connected to the mounting bracket, the Y-axis translation mechanism is connected to the X-axis translation mechanism, and the air source plug drive mechanism is connected to the Y-axis translation mechanism. The X-axis translation mechanism is used to adjust the position of the air source plug in the X-axis direction, and the Y-axis translation mechanism is used to adjust the position of the air source plug in the Y-axis direction.

[0027] By combining the X-axis translation mechanism and the Y-axis translation mechanism, the position of the air source plug is adjusted in the X-axis and Y-axis directions, ensuring that the air source plug is aligned with the air source socket.

[0028] In some embodiments, the gas source socket is provided with a guide hole, and the gas source plug is provided with a guide rod that matches the guide hole.

[0029] The guide rod and guide hole work together to guide the movement of the gas source plug, further ensuring that the gas source plug can be accurately inserted into the gas source socket. Attached Figure Description

[0054] The above-mentioned objectives, features and advantages of the present invention will become more apparent and understandable. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] Traditional pressurized heating methods involve placing stacked lithium batteries on a fixture, applying pressure by pressing them together with the fixture, and then transporting the lithium batteries, along with the fixture, into an oven for heating. This pressurized heating method has low efficiency.

[0056] In view of this, the present invention provides a pressurizing and heating device that can directly place stacked lithium batteries into a closed box, thereby automatically pressurizing and heating the lithium battery module and improving the pressurizing and heating efficiency of the lithium battery module.

[0057] like Figure 1 As shown, the pressurized heating device provided by the present invention includes a mounting bracket 10 and several pressurized heating boxes 20, wherein:

[0058] The mounting bracket 10 has several receiving cavities.

[0059] Each pressurized heating box 20 can be removably inserted into a receiving cavity. The pressurized heating box 20 is equipped with a pressurizing mechanism and a heating mechanism. The pressurizing mechanism is used to compress the lithium battery module located in the pressurized heating box 20, and the heating mechanism is used to heat the lithium battery module.

[0060] Figure 1 In this embodiment, the mounting bracket 10 has nine accommodating cavities. In actual use, the pressurized heating box 20 can be inserted into all nine accommodating cavities, at which point the pressurized heating device is in a fully loaded state, and its processing capacity reaches its maximum. Of course, the pressurized heating box 20 can also be inserted into only one or a few of the accommodating cavities, while the remaining accommodating cavities remain unloaded.

[0061] like Figure 2 and Figure 3 As shown, the pressurized heating box 20 includes a box body 21 and a flip cover 22. The box body 21 is provided with a material port for taking out and putting in lithium battery modules, and the flip cover 22 is located at the material port.

[0062] When the control flip cover 22 flips upward, the material inlet is opened. At this time, the lithium battery module to be processed can be put into the box 21, or the processed lithium battery module can be taken out from the box 21.

[0063] When the control flip cover 22 flips downward, the material inlet is closed. At this time, the box 21 is in a closed state, and the pressurizing mechanism and heating mechanism can heat and pressurize the lithium battery module placed in the box 21.

[0064] To enable automatic opening and closing of the flip cover 22, optionally, a flip connecting assembly 23 is provided on the upper edge of the feed inlet on the housing 21, and the upper end of the flip cover 22 is connected to the flip connecting assembly 23. Correspondingly, a flip driving assembly 13 is provided on the mounting bracket 10, which can drive the flip connecting assembly 23 to rotate, thereby causing the flip cover 22 to flip up and down.

[0065] Optionally, to prevent the inner wall of the flip cover 22 from contacting the lithium battery module, such as... Figure 4 As shown, a baffle 28 is connected to the inner wall of the flip cover 22.

[0066] Optional, such as Figure 4 and Figure 5 As shown, the pressurizing mechanism 26 includes a lifting drive mechanism 261 and a pressure plate 262. The lifting drive mechanism 261 is connected to the top wall of the pressurizing heating box 20, and the pressure plate 262 is connected to the drive end of the lifting drive mechanism 261. When the lifting drive mechanism 261 drives the pressure plate 262 to press down, the pressure plate 262 presses on the lithium battery module, thereby squeezing the lithium battery module.

[0067] Optional, such as Figure 4 and Figure 5 As shown, the pressurized heating chamber 20 is equipped with multiple pressurized heating stations, each capable of holding a set of lithium battery modules. Each pressurized heating station also includes a pressurizing mechanism 26 and a heating mechanism. This arrangement allows each pressurized heating chamber 20 to simultaneously pressurize and heat multiple sets of lithium battery modules, further improving the processing efficiency of the invention. Optionally, each heating mechanism includes a heating lamp 27 mounted on the mounting bracket 10 and located on the side of the corresponding pressurized heating station. The heating lamp 27 located on the side of the pressurized heating station provides close-range heating to the battery module located at that station, further enhancing the heating effect.

[0068] like Figure 3 and Figures 6 to 7 As shown, a power socket 24 is provided on the pressurized heating box 20. A set of power supply mechanisms 11 is provided on the mounting bracket 10 at the position corresponding to each accommodating cavity.

[0069] The power supply mechanism 11 includes a power plug drive mechanism 111 and a power plug 112. The power plug drive mechanism 111 is connected to the mounting bracket 10, and the power plug 112 is connected to the drive end of the power plug drive mechanism 111 and is matched with the power socket 24.

[0070] After the pressurized heating chamber 20 is installed into the accommodating cavity, the power socket 24 on the pressurized heating chamber 20 is brought close to the power supply mechanism 11 at the corresponding position. At this time, the power plug 112 is driven by the power plug drive mechanism 111 to move toward the power socket 24, thus achieving the connection between the power plug 112 and the power socket 24. The power supply mechanism 11 then begins to supply power to the pressurized heating chamber 20.

[0071] After heating and heat treatment are completed, the power plug 112 moves away from the power socket 24 via the power plug drive mechanism 111, thus detaching the power plug 112 from the power socket 24. The power supply mechanism 11 then stops supplying power to the pressurized heating chamber 20.

[0072] like Figure 3 and Figures 8 to 10 As shown, the pressurized heating box 20 is equipped with a gas source socket 25. A set of gas supply mechanisms 12 is provided on the mounting bracket 10 at the positions corresponding to each accommodating cavity. The gas supply mechanism 12 includes a gas source plug drive mechanism 122 and a gas source plug 123. The gas source plug drive mechanism 122 is connected to the mounting bracket 10, and the gas source plug 123 is connected to the drive end of the gas source plug drive mechanism 122 and matches the gas source socket 25.

[0073] After the pressurized heating box 20 is installed into the accommodating cavity, the gas source socket 25 on the pressurized heating box 20 is brought close to the corresponding gas supply mechanism 12. At this time, the gas source plug 123 is driven by the gas source plug drive mechanism 122 to move toward the gas source socket 25, thus achieving the connection between the gas source plug 123 and the gas source socket 25. The gas supply mechanism 12 then begins to supply gas to the pressurized heating box 20.

[0074] After heating and heat treatment are completed, the gas source plug 123 is driven away from the gas source socket 25 by the gas source plug drive mechanism 122, thus detaching the gas source plug 123 from the gas source socket 25. The gas supply mechanism 12 then stops supplying gas to the pressurized heating box 20.

[0075] Optional, such as Figure 8 and Figure 9 As shown, the gas supply mechanism 12 also includes a position adjustment assembly 121, which is mounted on the mounting bracket 10. The gas source plug drive mechanism 122 is connected to the position adjustment assembly 121. The position adjustment assembly 121 is used to adjust the position of the gas source plug 123 so that the gas source plug 123 is aligned with the gas source socket 25.

[0076] like Figure 10 As shown, optionally, the position adjustment assembly 121 includes an X-axis translation mechanism 1211 and a Y-axis translation mechanism 1212, wherein: the X-axis translation mechanism 1211 is connected to the mounting bracket 10, the Y-axis translation mechanism 1212 is connected to the X-axis translation mechanism 1211, and the air source plug drive mechanism 122 is connected to the Y-axis translation mechanism 1212. The X-axis translation mechanism 1211 is used to adjust the position of the air source plug 123 in the X-axis direction, and the Y-axis translation mechanism 1212 is used to adjust the position of the air source plug 123 in the Y-axis direction.

[0077] Driven by the combined X-axis translation mechanism 1211 and Y-axis translation mechanism 1212, the position adjustment component 121 adjusts the position of the air source plug 123 in the X-axis and Y-axis directions, thereby ensuring that the air source plug 123 is aligned with the air source socket 25.

[0078] like Figure 10 As shown, optionally, the gas source socket 25 is provided with a guide hole 251, and the gas source plug 123 is provided with a guide rod 124 that matches the guide hole. The gas source plug drive mechanism 122 drives the gas source plug 123 to move toward the gas source socket 25, and the guide rod 124 on the gas source plug 123 is inserted into the guide hole 251 of the gas source socket 25, so that the gas source plug 123 can be inserted into the gas source socket 25 more accurately and stably.

Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of the invention should fall within the protection scope of the invention.
