Description

[Technical Field]

[0001] This invention relates to the field of battery technology, and more particularly to an external packaging device for lithium battery production. [Background Technology]

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become mainstream. Lithium-ion batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Due to their high technological requirements, only companies in a few countries produce these lithium metal batteries. In the later stages of lithium-ion battery production, after the batteries are stacked together, a plastic sealing film is added to the outside of the battery stack. This film is then heated to shrink and cover the outside of the battery.

[0003] Existing external packaging equipment used in lithium battery production heats the outside of the battery unevenly during use, resulting in a concentrated heat source. This can cause uneven heating of the plastic sealant, preventing it from shrinking and covering properly. Furthermore, the residual heat inside the heating chamber of the equipment usually dissipates slowly after use, leading to a waste of thermal energy.

[0004] Therefore, it is necessary to provide an external packaging device for lithium battery production to overcome the above-mentioned defects. [Summary of the Invention]

[0005] The purpose of this invention is to provide an external packaging device for lithium battery production, which aims to improve the existing external packaging devices for lithium battery production. During use, the heating of the outer side of the battery is not uniform enough, the heat source is relatively concentrated, which easily causes uneven heating of the plastic film and makes it unable to shrink and cover. In addition, after the use is completed, the residual heat inside the heating chamber of the device usually dissipates slowly, resulting in the waste of heat energy.

[0006] To achieve the above objectives, the present invention provides an external packaging device for lithium battery production, comprising a base, a conveyor belt mounted on the top of the base, a heating frame connected to the top of the base, mounting frames fixedly mounted on the middle of both sides of the inner wall of the heating frame, a packaging heating tube fixedly mounted inside the mounting frame, a top pipe connected to the top of the inner wall of the heating frame, a top box fixedly connected to the top of the heating frame, a hot air blower fixedly mounted on the bottom of the inner wall of the top box, a connecting pipe fixedly connected to the output end of the hot air blower, one end of the connecting pipe being connected to the top pipe, a support plate fixedly connected to the bottom of the base, and a [missing information - likely a device or equipment] fixedly mounted on the top of the support plate. A heat collection box has a first fan installed on one side of the bottom of its inner wall. The input end of the first fan is connected to a heat absorption pipe, which is connected to one side of a heating frame. A second fan is installed on the other side of the bottom of the inner wall of the heat collection box. The output end of the second fan is connected to a heat exhaust pipe, which is connected to the other side of the heating frame. Limiting guide mechanisms for limiting the battery are installed on the bottom of both sides of the inner wall of the heating frame. The limiting guide mechanism includes a moving plate, several electric telescopic rods, and several guide rollers. One side of the moving plate is connected to the output end of several electric telescopic rods, and the other side of the moving plate is connected to one side of several guide rollers.

[0007] In a preferred embodiment, a switch panel is fixedly installed on one side of the front of the base. The conveyor belt, the encapsulation heating tube, the first fan, the second fan, the hot air blower, and the electric telescopic rod are all electrically connected to an external power source through the switch panel. The switch panel is used to control the conveyor belt, the encapsulation heating tube, the first fan, the second fan, the hot air blower, and the electric telescopic rod.

[0008] In a preferred embodiment, the end of the connecting pipe away from the hot air blower is fixedly connected to the top of the top pipe, and the connecting pipe is used by the hot air blower to blow hot air into the heating frame.

[0009] In a preferred embodiment, the bottom of the top pipe is fixedly connected to a plurality of ventilation hoods for uniform air blowing, and the plurality of ventilation hoods are arranged vertically downward.

[0010] In a preferred embodiment, the heat-absorbing pipe is connected to the interior of one side of the heating frame at one end away from the first fan, and the heat-dissipating pipe is connected to the interior of the other side of the heating frame at one end away from the second fan.

[0011] In a preferred embodiment, the inner wall of the heat collection box is fixedly connected with an insulation pad to reduce heat loss, and a vent valve for venting the heat collection box is installed at the bottom of one side of the heat collection box. The insulation pad improves the heat preservation effect of the heat collection box.

[0012] In a preferred embodiment, the bottom of the front side and the bottom of the back side of the heating frame are both fixedly connected to a reinforcing plate for reinforcing the heating frame, and the reinforcing plate is fixedly connected to the surface of the base.

[0013] In a preferred embodiment, the top of both sides of the heating frame is fixedly connected to a fixing plate for side blocking, and the bottom of the fixing plate is connected to a plurality of heat-insulating plastic curtains to reduce heat loss inside the heating frame. The heat-insulating plastic curtains can reduce the outward discharge of heat inside the heating frame.

[0014] In a preferred embodiment, the bottom of the heating frame is fixedly connected to the top surface of the base, and an observation window is provided in the middle of the front of the heating frame to facilitate observation of the interior of the heating frame, so that the condition inside the heating frame can be viewed.

[0015] In a preferred embodiment, the two limiting guide mechanisms are symmetrically arranged, and one end of the plurality of electric telescopic rods away from the moving plate is fixedly connected to the surface of the inner wall of the heating frame.

[0016] The external packaging equipment for lithium battery production provided by this invention involves activating a conveyor belt to transport batteries into a heating frame. A packaging heating pipe in the middle of the inner wall of the heating frame heats and thermally packages the passing batteries. A hot air blower, through connecting pipes and a top pipe, blows air into the heating frame, resulting in more uniform heat distribution and better packaging of the batteries. As the batteries pass through the heating frame, a limiting and guiding mechanism is activated. The first fan of the limiting and guiding mechanism extends and pushes a guide roller to the side of the battery, guiding and limiting the battery to prevent displacement or tilting during transport. After the battery packaging is completed, the first fan is activated to draw hot air from inside the heating frame into a heat collection box through a heat absorption pipe for storage, thereby reducing heat energy waste. Later, a second fan can be activated to draw the hot air back into the heating frame through a heat exhaust pipe for reuse. [Attached Image Description]

[0028] Please see Figure 1-6In an embodiment of the present invention, an external packaging device for lithium battery production is provided, comprising a base 1, a conveyor belt 2 mounted on the top of the base 1, a heating frame 3 connected to the top of the base 1, mounting frames 11 fixedly mounted on the middle of both sides of the inner wall of the heating frame 3, a packaging heating tube 12 fixedly mounted inside the mounting frame 11, a top tube 13 connected to the top of the inner wall of the heating frame 3, a top box 8 fixedly connected to the top of the heating frame 3, a hot air blower 20 fixedly mounted on the bottom of the inner wall of the top box 8, a connecting pipe 21 fixedly connected to the output end of the hot air blower 20, one end of the connecting pipe 21 connected to the top tube 13, a support plate 6 fixedly connected to the bottom of the base 1, a heat collection box 7 fixedly mounted on the top of the support plate 6, a first fan 15 mounted on one side of the bottom of the inner wall of the heat collection box 7, a heat absorption pipe 17 connected to the input end of the first fan 15, the heat absorption pipe 17 connected to one side of the heating frame 3, and the other side of the bottom of the inner wall of the heat collection box 7 A second fan 16 is installed, and the output end of the second fan 16 is connected to a heat exhaust pipe 18. The heat exhaust pipe 18 is connected to the other side of the heating frame 3. Limiting guide mechanisms 22 for limiting the battery are installed at the bottom of both sides of the inner wall of the heating frame 3. The limiting guide mechanism 22 includes a moving plate 24, several electric telescopic rods 25 and several guide rollers 26. One side of the moving plate 24 is connected to the output end of several electric telescopic rods 25, and the other side of the moving plate 24 is connected to one side of several guide rollers 26. In this embodiment, after the stacked batteries are packaged with a sealing film, they are placed on the conveyor belt 2. The conveyor belt 2 is started to transport the batteries into the heating frame 3. The sealing heating pipe 12 in the middle of the inner wall of the heating frame 3 heats and heats the passing batteries to perform heat sealing, so that the sealing film is heated and tightened. The hot air blower 20 can blow air evenly into the heating frame 3 through the connecting pipe 21 and the top pipe 13, so that the batteries are more evenly distributed.

[0029] See Figure 1-6 A switch panel 5 is fixedly installed on one side of the front of the base 1. The conveyor belt 2, the encapsulated heating tube 12, the first fan 15, the second fan 16, the hot air fan 20, and the electric telescopic rod 25 are all electrically connected to an external power supply through the switch panel 5. The end of the connecting pipe 21 away from the hot air fan 20 is fixedly connected to the top of the top pipe 13. Several ventilation hoods 14 for uniform air blowing are fixedly connected to the bottom of the top pipe 13. Several ventilation hoods 14 are set vertically downward. In this embodiment, when the hot air fan 20 is started, hot air can be circulated into the top pipe 13 through the connecting pipe 21. Finally, the hot air inside the top pipe 13 is evenly blown out into the heating frame 3 through the ventilation hoods 14.

[0030] See Figure 1-6The end of the heat-absorbing pipe 17 away from the first fan 15 is connected to the interior of one side of the heating frame 3, and the end of the heat-dissipating pipe 18 away from the second fan 16 is connected to the interior of the other side of the heating frame 3. A heat-insulating pad 19 to reduce heat loss is fixedly connected to the surface of the inner wall of the heat collection box 7. A vent valve 23 for venting the heat collection box 7 is installed at the bottom of one side of the heat collection box 7. A reinforcing plate 4 for reinforcing the heating frame 3 is fixedly connected to the bottom of the front and the bottom of the back of the heating frame 3. The reinforcing plate 4 is fixedly connected to the surface of the base 1. After the battery encapsulation is completed in this embodiment, the first fan 15 is started to work and the residual hot air inside the heating frame 3 is drawn into the heat collection box 7 through the heat-absorbing pipe 17 for storage, thereby avoiding the waste of heat energy. Later, the hot air can be drawn back into the heating frame 3 for reuse by starting the second fan 16 through the heat-dissipating pipe 18.

[0031] See Figure 1-6 The top of both sides of the heating frame 3 is fixedly connected with a fixing plate 9 for side partitioning. The bottom of the fixing plate 9 is connected with several heat-insulating plastic curtains 10 to reduce heat loss inside the heating frame 3. The bottom of the heating frame 3 is fixedly connected to the surface of the top of the base 1. The center of the front of the heating frame 3 is provided with an observation window 27 for easy observation of the inside of the heating frame 3. Two limiting guide mechanisms 22 are symmetrically arranged. The ends of several electric telescopic rods 25 away from the moving plate 24 are fixedly connected to the surface of the inner wall of the heating frame 3. In this embodiment, when the battery passes through the inside of the heating frame 3, the limiting guide mechanism 22 can be activated by the switch panel 5. The first fan 15 of the limiting guide mechanism 22 extends and pushes the guide roller 26 to move to the side of the battery to guide and limit the battery, so as to prevent the battery from shifting or tilting during transportation.

[0032] In practical use, the external packaging equipment for lithium battery production of this invention involves packaging stacks of batteries with packaging films and placing them on a conveyor belt 2. The conveyor belt 2 is activated via a switch panel 5 to transport the batteries into a heating frame 3. The packaging heating tube 12 in the middle of the inner wall of the heating frame 3 heats and thermally seals the passing batteries, causing the packaging film to tighten due to heat. Furthermore, the hot air blower 20 blows air into the heating frame 3 through the connecting pipe 21 and the top pipe 13, resulting in a more uniform heat distribution. The batteries are heated more evenly inside the heating frame 3, leading to better packaging. Additionally, as the batteries pass through the heating frame 3, the heat distribution is improved. The limiting guide mechanism 22 is activated via the switch panel 5. The first fan 15 of the limiting guide mechanism 22 extends and pushes the guide roller 26 to move to the side of the battery to guide and limit the battery, preventing it from shifting or tilting during transportation. After the battery encapsulation is completed, there is still residual heat inside the heating frame 3. The first fan 15 is activated via the switch panel 5 to draw the hot air inside the heating frame 3 into the heat collection box 7 through the heat absorption pipe 17 for storage, thereby avoiding the waste of heat energy. Later, the second fan 16 can be activated to draw the hot air back into the heating frame 3 through the heat exhaust pipe 18 for reuse, saving energy.
