Description

Technical Field

[0001] The invention relates to the technical field of automobile lithium battery processing, in particular to an automobile lithium battery shaping device. Background Art

[0002] Automotive lithium batteries are lithium-ion batteries used in electric vehicles or hybrid vehicles. Charging and discharging are achieved through the migration of lithium ions between the positive and negative electrodes. They are mainly composed of positive electrode materials, negative electrode materials, diaphragms, electrolytes and casings. They have the characteristics of high energy density, long cycle life and light weight. In the production process of lithium batteries, after the battery cells undergo winding or lamination processes, the internal materials may be slightly deformed due to process errors or material expansion.

Beneficial Effects

[0015] 1. The present invention separates the high-temperature oil and the cooling water flow channel through a flexible diaphragm in the double-cavity heat-conducting film. In the heating stage, the high-temperature oil squeezes the diaphragm to make it fit the inner wall of the cooling flow channel to achieve full coverage of the hot runner. In the cooling stage, the reverse operation is performed to completely replace the hot oil with cold water. This design allows the heating and cooling areas to completely overlap, eliminating the temperature difference fluctuations caused by medium residue in the traditional solution, improving the heat exchange efficiency, and avoiding medium mixing contamination, effectively improving the mold temperature control response speed, and improving the lithium battery shaping yield.

[0016] 2. When the hydraulic cylinder of the present invention drives the lifting plate, the bottom inclined driving plate and the sliding rod are linked to trigger the rotation of the rotating shaft, automatically removing the cover plate from blocking the shunt pipe and the drain pipe, thereby realizing the rapid docking of the collecting pipe and the shunt pipe. During the flow of the medium, the sealing plug will automatically open the flow channel under the pressure of the medium, and the O-ring will ensure the sealing. When the upper and lower molds are separated, the reset spring will push the limit plate to reset, and the sealing plug will close the flow channel and link the cover plate to return to its position. The whole process does not require manual intervention, which is more convenient.

[0017] 3. The toothed plate of the present invention meshes with the double gears to drive the screw to control the position of the orifice plate, and the opening and closing states of the plug and the drain pipe are controlled by the compression spring. Therefore, when hot oil is introduced, the oil pressure is increased due to the spring pressure, and the drain pipe on the other side is opened to realize the rapid drainage of cooling water. The reverse operation in the cooling stage enables the cold water to efficiently replace the hot oil, which greatly shortens the medium switching time. In addition, the present application also cooperates with the ejector plate to automatically eject the product with the lifting action, thereby realizing the automation of the entire process of shaping, cooling, and demoulding, and improving the overall production efficiency.

DETAILED DESCRIPTION

[0020] See also Figures 1 to 5 The automotive lithium battery shaping device provided by the present invention includes a workbench 1 and a heat exchange component 5. A pressure component 2 is arranged on the top of the workbench 1, and an upper mold 3 is placed on the middle bottom surface of the pressure component 2. A lower mold 4 is fixed in the center of the top of the workbench 1, and the heat exchange component 5 is arranged inside the upper mold 3 and the lower mold 4.

[0021] In some embodiments, the above-mentioned heat exchange component 5 includes a first heat-conducting pipe 501, the first heat-conducting pipe 501 is arranged inside the lower mold 4, and one end of the first heat-conducting pipe 501 is connected to the first collecting pipe 502, and the end of the first collecting pipe 502 is provided with a liquid inlet pipe 503, the other end of the first heat-conducting pipe 501 is fixed with a first diverter pipe 504, and a second collecting pipe 505 is provided above the first diverter pipe 504, one end of the second collecting pipe 505 is connected to the second heat-conducting pipe 506, and the second heat-conducting pipe 506 is fixedly connected to the upper mold 3, and the second heat-conducting pipe 506 and the first heat-conducting pipe 501 are both provided with a double-cavity heat-conducting film 507, the other end of the second heat-conducting pipe 506 is connected to the second diverter pipe 508, and a drain pipe 509 is provided below the second diverter pipe 508, and the drain pipe 509 is fixedly connected to the workbench 1.

[0022] The pressure-applying assembly 2 includes a frame 201, the frame 201 is placed on the top of the workbench 1, and a hydraulic cylinder 202 is fixed at the top center of the frame 201, a lifting plate 203 is connected to the bottom of the hydraulic cylinder 202, and the lifting plate 203 is slidably connected to the frame 201, a pressure sensor 204 is arranged at the bottom of the lifting plate 203, and a mounting plate 205 is fixed to the bottom of the pressure sensor 204; The specific operation is as follows: the first heat-conducting pipe 501 and the second heat-conducting pipe 506 are separated into two flow channels by using the flexible heat-conducting diaphragm inside the double-cavity heat-conducting film 507. Therefore, during the shaping process of the battery core, when the temperature needs to be increased, the oil at the specified temperature is transported to one of the liquid inlet pipes 503 through the external pump body. Since there are two flow channels inside the first collecting pipe 502, and one end of the outlet is respectively connected to the two flow channels inside the double-cavity heat-conducting film 507, during use, the double-cavity heat-conducting film 507 will be deformed under the pressure of the oil, so that the central diaphragm fits with the inner wall of the other flow channel, so that only high-temperature oil can be stored in the first heat-conducting pipe 501, and the two flow channels inside the first shunt pipe 504, the second collecting pipe 505 and the second shunt pipe 508 are the same as the first collecting pipe 502, and are also respectively connected to the two flow channels inside the double-cavity heat-conducting film 507, so that the high-temperature oil can also flow to the second heat-conducting pipe 506. The heat pipe 501 is distributed in a bent shape inside and outside the lower end of the lower mold 4, and the second heat pipe 506 is distributed in a bent shape inside the upper mold 3, so that the product is heated evenly during the hot pressing process and the shaping effect is enhanced. When the product needs to be cooled after hot pressing and shaping, it is only necessary to discharge the hot oil inside the double-cavity heat-conducting film 507 first, and then pass cold water from another liquid inlet pipe 503 into another flow channel of the double-cavity heat-conducting film 507 through an external pump body. Similarly, the diaphragm inside the double-cavity heat-conducting film 507 will deform again, thereby fitting with the other side, so that only cold water is stored in the first heat pipe 501 and the second heat pipe 506. Therefore, in the process of temperature control, the heating part and the cooling part are in the same position and are evenly distributed inside the mold, which is beneficial to improving the effect of heat exchange. At the same time, the heat exchange medium will not interfere with each other. In the heat exchange process, by discharging another heat exchange medium, the heat transfer between the heat exchange media is reduced, and the loss of heat exchange efficiency is reduced.

[0023] See also Figure 6 and Figure 7 A connecting component 6 is provided at the top of the first diversion pipe 504 and the drain pipe 509.

[0024] In some embodiments, the connecting component 6 includes a rotating shaft 601, and the outer sides of the upper ends of the first diversion pipe 504 and the discharge pipe 509 are rotatably connected to the rotating shaft 601, and a torsion spring 602 is arranged on the outer side of the lower end of the rotating shaft 601, and a sliding rod 603 is fixed to the bottom of the torsion spring 602, and the sliding rod 603 is fixedly connected to the rotating shaft 601, and a cover plate 604 is arranged on the top of the rotating shaft 601, and driving plates 605 are symmetrically arranged at both ends of the bottom of the mounting plate 205, and the bottom of the driving plate 605 is inclined, and the driving plate 605 corresponds to the sliding rod 603 one by one, and the lower ends of the second collecting pipe 505 and the second diversion pipe 508 are both provided with leak-proof components 7, and the leak-proof components 7 on both sides are oriented in opposite directions.

[0025] The anti-leakage component 7 includes an O-ring 701, and the O-ring 701 is embedded on the outer side of the lower end of the second collecting pipe 505 and the second diversion pipe 508, and a fixing ring 702 is fixed inside the second collecting pipe 505 and the second diversion pipe 508, a sealing plug 703 is provided on one side of the fixing ring 702, and a connecting rod 704 is arranged in the middle of the sealing plug 703, the end of the connecting rod 704 is connected to the limiting plate 705, and a return spring 706 is provided on one side of the limiting plate 705.

[0026] The specific operation is as follows: the hydraulic cylinder 202 on the frame 201 drives the lifting plate 203 to move downward, so that when the upper mold 3 and the lower mold 4 are docked, the driving plate 605 will also be driven to contact the slide bar 603. Since the bottom of the driving plate 605 is inclined, the slide bar 603 will rotate the rotating shaft 601 under its limit, so that the cover plate 604 can be automatically moved away from the top of the first shunt pipe 504 and the drain pipe 509, and the second collecting pipe 505 can be inserted into the first shunt pipe 504 and the drain pipe 509 to automatically complete the docking operation. Later, when the internal heat exchange medium is transported, the pressure of the heat exchange medium will push the sealing plug 703, so that the first heat conducting pipe 501 and the second heat conducting pipe 506 is internally circulated, and the use of O-ring 701 can improve the sealing performance during the connection process. After shaping, when the upper mold 3 is separated from the lower mold 4, the reset spring 706 will push the limit plate 705 under the limit of the fixed ring 702, and the connecting rod 704 will pull the sealing plug 703 to make it close to the fixed ring 702, so that a certain pressure can be used to seal the lower end of the second collecting pipe 505 and the second diverter pipe 508. At the same time, the driving plate 605 is separated from the sliding rod 603, and the torsion spring 602 will drive the rotating shaft 601 to reset, so that the cover plate 604 will cover the top of the first diverter pipe 504 and the drain pipe 509 again, so that no additional manual operation is required, which is more convenient.

[0027] See also Figure 1 , Figure 2 and Figure 8 One end of the discharge pipe 509 is connected to the adjustment component 8.

[0028] The adjustment component 8 includes a bracket 801, a bracket 801 is fixed on one side of the workbench 1, and an electric push rod 802 is placed on the top of the bracket 801, a toothed plate 803 is connected to the bottom of the electric push rod 802, and gears 804 are meshed on both sides of the toothed plate 803, a screw sleeve 805 is fixed inside the gear 804, and the outer side of the screw sleeve 805 is rotatably connected to a fixed box 806, and the fixed box 806 is fixedly connected to the workbench 1, a screw 807 is threadedly connected to the inner side of the screw sleeve 805, and a hole plate 808 is fixed to one side of the screw 807, and the hole plate 808 slides with the fixed box 806 The middle part of the orifice plate 808 is slidably connected with a guide rod 809, and a plug 810 is fixed to the guide rod 809, and a compression spring 811 is provided on one side of the plug 810, and a stripping assembly 9 is connected to one side of the lifting plate 203, and the stripping assembly 9 includes a bracket 901, a bracket 901 is fixed to one side of the lifting plate 203, and the bracket 901 is L-shaped, a pin plate 902 is provided at the lower end of the bracket 901, and the pin plate 902 is slidably connected to the lower mold 4, and the inner sliding connection of the pin plate 902 is a limit rod 903, and the limit rod 903 is fixedly connected to the workbench 1.

[0029] It should be noted that when the middle of the toothed plate 803 is located between the two gears 804, the positions of the orifice plates 808 inside the two fixed boxes 806 are flush, and when one end of the toothed plate 803 is moved between the two gears 804 by the electric push rod 802, the two gears 804 will rotate in different directions, so that through the screw sleeve 805 and the screw rod 807, one orifice plate 808 is close to the plug 810, and the compression spring 811 can be used to provide a larger elastic force, while the other orifice plate 808 is close to the plug 810. 8 will approach the screw sleeve 805 and pull the plug 810 through the guide rod 809 to separate it from the drain pipe 509. Therefore, when hot oil is introduced into one of the drain pipes 509, the oil pressure is increased by using the relatively elastic compression spring 811, and the end of the other drain pipe 509 is not blocked, so the cooling water inside can flow out directly. Therefore, the oil inside the double-cavity heat-conducting membrane 507 can squeeze out the cooling water and be quickly discharged from the double-cavity heat-conducting membrane 507 to reduce interference.

[0030] During cooling, it is only necessary to make the electric push rod 802 drive the tooth plate 803 to move back, so that the plug 810 in the hot oil can be separated from the drain pipe 509, and the plug 810 in the cold water can be tightly attached to the drain pipe 509. At this time, cooling water is transported through the external pump body. Similarly, the hot oil inside the double-cavity heat-conducting membrane 507 can be quickly squeezed out, so that the cooling water fills the inside of the double-cavity heat-conducting membrane 507, thereby improving the efficiency of switching the heat exchange medium. Subsequently, when the lifting plate 203 drives the upper mold 3 and the lower mold 4 to separate, it will also drive the ejector plate 902 to slide upward along the limit rod 903 through the bracket 901, so that the product inside the lower mold 4 can be automatically ejected, which is convenient for unloading.

[0031] In summary, when using the automotive lithium battery shaping device of the present invention, the battery cell is first placed in the lower mold 4, and then the hydraulic cylinder 202 on the frame 201 is started to drive the lifting plate 203 to move downward, so that the upper mold 3 and the lower mold 4 are docked, and at the same time, the driving plate 605 is driven to contact the slide bar 603, and the slide bar 603 will rotate the rotating shaft 601 under its limit, so that the cover plate 604 can be automatically moved away from the top of the first shunt pipe 504 and the drain pipe 509, and the second collecting pipe 505 can be inserted into the first shunt pipe 504 and the drain pipe 509 to automatically complete the docking operation, and then, the electric push rod 802 is started to move one end of the tooth plate 803 between the two gears 804, and the two gears 804 will rotate in different directions, so that a hole plate 808 is close to the plug 8 through the screw sleeve 805 and the screw rod 807. 10, the compression spring 811 can be used to provide a larger elastic force, and the other orifice plate 808 will be close to the screw sleeve 805, and the plug 810 will be pulled by the guide rod 809 to separate it from the drain pipe 509. After that, when the temperature needs to be increased, the oil of the specified temperature is transported to one of the inlet pipes 503 through the external pump body. Since there are two flow channels inside the first header 502, and one end of the outlet is respectively connected with the two flow channels inside the double-cavity heat-conducting film 507, and the two flow channels inside the first shunt pipe 504, the second header 505 and the second shunt pipe 508 are the same as the first header 502, and are also respectively connected with the two flow channels inside the double-cavity heat-conducting film 507. Moreover, the pressure of the heat exchange medium will push the sealing plug 703, so that the first heat-conducting pipe 501 and the second heat-conducting pipe 506 are in communication. In addition, the use of O-ring 701 can improve the sealing performance during the connection process, so that the high-temperature oil can flow into the second heat-conducting pipe 506 and then flow into the drain pipe 509. At this time, the compression spring 811 with greater elasticity can be used to increase the oil pressure, and the end of the other drain pipe 509 is not blocked, so the internal cooling water can flow out directly, and the double-cavity heat-conducting film 507 will deform under the squeeze of the oil, so that the central diaphragm fits with the inner wall of the other flow channel, and the cooling water is quickly squeezed out of the double-cavity heat-conducting film 507 to reduce interference. At the same time, the first heat-conducting pipe 501 is distributed in a bent shape inside and outside the lower end of the lower mold 4, and the second heat-conducting pipe 506 is distributed in a bent shape inside the upper mold 3. Inside, so that the product is heated evenly during the hot pressing process, then, during the pressing process, the pressure sensor 204 is used to monitor the pressure. Later, when the product needs to be cooled, it is only necessary to make the electric push rod 802 drive the tooth plate 803 to move back, so that the plug 810 in the hot oil can be separated from the drain pipe 509, and the plug 810 in the cold water can be tightly attached to the drain pipe 509, and then the cold water is passed from the other inlet pipe 503 to the other flow channel of the double-cavity heat-conducting film 507 through the external pump body, and the diaphragm inside the double-cavity heat-conducting film 507 will be deformed again, so as to fit with the other side, so that only cold water is stored in the first heat-conducting pipe 501 and the second heat-conducting pipe 506, and the product is quickly cooled down; Finally, after shaping, the hydraulic cylinder 202 drives the lifting plate 203 to move upward to separate the upper mold 3 from the lower mold 4. The reset spring 706 will push the limit plate 705 under the limit of the fixed ring 702, and the connecting rod 704 will pull the sealing plug 703 to make it close to the fixed ring 702, so that a certain pressure can be used to seal the lower ends of the second collecting pipe 505 and the second diverter pipe 508. At the same time, the driving plate 605 is separated from the sliding rod 603, and the torsion spring 602 will drive the rotating shaft 601 to reset, so that the cover plate 604 will cover the top of the first diverter pipe 504 and the drain pipe 509 again. At the same time, the lifting plate 203 will also drive the ejector plate 902 to slide upward along the limit rod 903 through the bracket 901, so that the product inside the lower mold 4 can be automatically ejected for easy unloading.
