[0002] The lithium iron phosphate power battery packaging device is a device used to combine lithium iron phosphate battery cells, protection boards, shells and other components into a complete battery pack. The battery cell is the core component of the battery pack and is responsible for storing and releasing electrical energy. The protection board installation device is used to install and protect the battery protection board to prevent abnormal conditions such as battery overcharging, over-discharging and short circuit. Finally, the shell packaging device encapsulates the battery cell, protection board and other components in the shell to form a complete battery pack.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 10 As shown, this embodiment provides an embodiment of a lithium iron phosphate power battery packaging device.

[0035] A lithium iron phosphate power battery packaging device, comprising a device body 1 and a conveying device 2, a battery shell 3 is placed on the conveying device 2, a clamping structure 4 is arranged on the device body 1, the clamping structure 4 comprises a plurality of first electric telescopic rods 5 fixedly mounted on the top of the device body 1, a connecting plate 6 is fixedly mounted on the output end of the first electric telescopic rod 5, a plurality of first gears 7 are movably mounted on the top of the connecting plate 6, a second gear 8 is fixedly mounted on the first gear 7, a fixing plate 9 connected to the connecting plate 6 is fixedly mounted between the first gears 7, a first tooth plate 10 is movably mounted on the connecting plate 6, a screw rod 11 connected to the fixing plate 9 is movably mounted on the first tooth plate 10, and a third gear 12 is fixedly mounted on one end of the screw rod 11;

[0036] A driving motor 13 is fixedly mounted on one end of the connecting plate 6, a fourth gear 14 meshing with the third gear 12 is fixedly mounted on the output end of the driving motor 13, a plurality of second tooth plates 15 meshing with the first gear 7 are movably mounted on the connecting plate 6, a clamping claw 16 is mounted on one end of the second tooth plate 15, and through the setting of the clamping structure 4, a structure for clamping and fixing the battery housing 3 is added to the original structure of the device body 1, so that the battery cells can be accurately positioned during the packaging process, so that the spacing between the battery cells is consistent, and the overall performance and safety of the battery pack will not be affected;

[0037] When packaging the battery, the battery shell 3 is first placed on the conveying device 2 to be conveyed on the device body 1. When the battery box is installed inside the battery shell 3, the multiple first electric telescopic rods 5 are first started to contract to drive the connecting plate 6 to descend until the second tooth plate 15 is sleeved on the outer side of the battery shell 3, and then the driving motor 13 is started to drive the fourth gear 14 to rotate. Due to the connection relationship between the fourth gear 14 and the third gear 12, when the fourth gear 14 rotates, the third gear 12 will also rotate;

[0038] The rotation of the third gear 12 can drive the screw rod 11 to rotate, and the rotation of the screw rod 11 can drive the first tooth plate 10 to move on the connecting plate 6. Since the first tooth plate 10 is in a meshing relationship with the multiple second gears 8, the first tooth plate 10 can drive the two first gears 7 to rotate relative to each other during the movement. When the two first gears 7 rotate relative to each other, they can drive the two second tooth plates 15 to move closer to or away from each other. Therefore, the spacing of the clamping claws 16 can be adjusted to clamp and fix the battery casing 3 to prevent it from shaking. The advantage of the adjustable spacing of the clamping claws 16 is that it can be suitable for clamping battery casings 3 of different specifications. The advantage of this structure is that it can prevent the battery cell from moving or dislocating during the packaging process, and prevent the instability of the packaging process from increasing the difficulty and cost of packaging.

[0039] like Figure 5 As shown, a protective shell 17 is fixedly installed on the outer side of the drive motor 13, and a plurality of heat dissipation holes 18 are opened on the protective shell 17. An inspection cover 19 is arranged on the top of the protective shell 17. The arrangement of the protective shell 17, the heat dissipation holes 18 and the inspection cover 19 can protect the drive motor 13 and prevent the drive motor 13 from being damaged by accidental contact. The heat dissipation holes 18 can dissipate the heat generated by the operation of the drive motor 13 to prevent the internal heat accumulation of the protective shell 17 and cause the drive motor 13 to malfunction. Opening the inspection cover 19 can facilitate personnel to inspect the drive motor 13 without disassembling the protective shell 17, thereby saving personnel's working time.

[0040] like Figure 5As shown, a first magnetic ring 20 is fixedly installed on the protective shell 17, and a second magnetic ring 21 magnetically connected to the first magnetic ring 20 is fixedly installed on the inner side of the inspection cover 19. Through the arrangement of the first magnetic ring 20 and the second magnetic ring 21, the inspection cover 19 can be fixed on the protective shell 17 to prevent it from falling off after the two are attracted to each other. Due to the characteristics of the first magnetic ring 20 and the second magnetic ring 21, the inspection cover 19 can be opened by directly pulling it without tools, thereby saving the time for personnel to open the inspection cover 19.

[0041] like Figure 6 As shown, one end of the clamping claw 16 is fixedly installed with a first fixed frame 22 connected to the second tooth plate 15, and the second tooth plate 15 and the first fixed frame 22 are both provided with connecting holes 23. A first plug rod 24 is movably installed inside the connecting hole 23, and a clamping bolt 25 is fixedly installed at one end of the first plug rod 24. A plurality of protrusions 26 are fixedly installed at the other end of the first plug rod 24. Through the arrangement of the first fixed frame 22, the connecting hole 23, the first plug rod 24, the clamping bolt 25 and the protrusion 26, after the first plug rod 24 is inserted into the interior of the connecting hole 23, the first plug rod 24 is rotated. After an insert rod 24 adjusts the angle of the bolt 25 to be perpendicular to the angle of the connecting hole 23, the second tooth plate 15 can be fixed inside the first fixed frame 22 to prevent it from falling off. The first insert rod 24 is rotated to adjust the angle of the bolt 25 to be consistent with the connecting hole 23, and the first insert rod 24 can be pulled out, thereby facilitating the disassembly and replacement of the clamping claw 16 when it is damaged. The multiple protrusions 26 set at the other end of the first insert rod 24 can prevent the person's hands from slipping when rotating the first insert rod 24, thereby facilitating the installation and disassembly of the first insert rod 24.

[0042] like Figure 7 As shown, a slide groove 27 is provided on the connecting plate 6, and a slider 28 connected to the second tooth plate 15 is movably installed inside the slide groove 27. Through the arrangement of the slide groove 27 and the slider 28, the friction between the second tooth plate 15 and the connecting plate 6 can be reduced, so that the slider 28 can slide more smoothly inside the slide groove 27, which can not only reduce the wear between the second tooth plate 15 and the connecting plate 6, but also improve the working efficiency of the clamping structure 4.

[0043] like Figure 3 As shown, a plurality of telescopic legs 29 are installed at the bottom of the device body 1, and a plurality of universal wheels 30 are arranged on the device body 1. Through the arrangement of the telescopic legs 29 and the universal wheels 30, when the device body 1 needs to move, the plurality of telescopic legs 29 are simultaneously started to retract until the universal wheels 30 touch the ground, and the device body 1 can be shifted under the rolling of the plurality of universal wheels 30. After the movement of the device body 1 is completed, the telescopic legs 29 are started to extend so that the universal wheels 30 touch the ground, so that the universal wheels 30 can leave the ground and be suspended in the air. With the support of the plurality of telescopic legs 29, the stability of the device body 1 can be ensured, thereby saving the time for personnel to carry the device body 1.

[0044] like Figure 4 As shown, a material transport trolley 31 is provided on one side of the conveying device 2, and a second electric telescopic rod 32 is fixedly installed on the top of the material transport trolley 31, and a placement box 33 is installed on the telescopic end of the second electric telescopic rod 32. Through the arrangement of the material transport trolley 31, the second electric telescopic rod 32 and the placement box 33, when the battery pack is packaged, it will be transported to one end of the conveying device 2, and then the material transport trolley 31 will move to one end of the conveying device 2, and then the second electric telescopic rod 32 will be started to extend to drive the placement box 33 to lift it upward so that it is at the same level as the conveying device 2. The battery pack after packaging can enter the interior of the placement box 33, and then be transported to the next work area by the material transport trolley 31. Automated handling can save labor.

[0045] like Figure 7 As shown, a through hole 34 is provided on the placement box 33, a fixing frame 35 connected to the placement box 33 is fixedly installed on the outer side of the through hole 34, a third electric telescopic rod 36 is fixedly installed on the inner side of the fixing frame 35, and a suction cup 37 connected to the battery shell 3 is fixedly installed on the output end of the third electric telescopic rod 36. Through the arrangement of the through hole 34, the fixing frame 35, the third electric telescopic rod 36 and the suction cup 37, when the packaged battery shell 3 enters the interior of the placement box 33, multiple third electric telescopic rods 36 are started at the same time to drive the suction cup 37 to move until it is adsorbed on the battery shell 3, which can improve the stability of the battery shell 3, thereby preventing the battery shell 3 from falling due to inertia when the material transport trolley 31 moves.

[0046] like Fig. 9 and Fig.10 As shown, a fixing block 38 is fixedly installed at the output end of the second electric telescopic rod 32, and a plurality of mounting holes 39 are opened on the fixing block 38. A spring 40 is fixedly installed inside the mounting hole 39, and a clamping block 41 is fixedly installed at one end of the spring 40. A second fixing frame 42 connected to the fixing block 38 is fixedly installed at the bottom of the placement box 33, and a plurality of clamping holes 43 used in conjunction with the clamping block 41 are opened on the second fixing frame 42. By setting the fixing block 38, the mounting holes 39, the spring 40, the clamping block 41, the second fixing frame 42 and the clamping holes 43, when the fixing When the block 38 is inserted into the second fixed frame 42, the card block 41 will be squeezed and contracted to the inside of the mounting hole 39. When the card block 41 moves to the position of the card hole 43, the card block 41 will pop out and engage in the inside of the mounting hole 39 under the elastic action of the spring 40, so that the fixed block 38 can be fixed in the second fixed frame 42 to prevent it from falling off. At the same time, pressing multiple card blocks 41 to shrink them to the inner side of the second fixed frame 42 can remove the fixed block 38 from the second fixed frame 42, so that it is convenient to disassemble and replace the placement box 33 when it is damaged.

[0047] like Fig. 9 and Fig.10 As shown, a plurality of limit plates 44 are fixedly mounted on the second fixed frame 42, a push block 45 is movably mounted between the limit plates 44, a limit rod 46 is fixedly mounted on one end of the push block 45, a limit hole 47 adapted to the limit rod 46 is opened on the clamping block 41, a plurality of plug holes 48 are opened on the limit plate 44, a second plug rod 49 connected to the push block 45 is installed on the limit plate 44, and the limit plate 44, the push block 45, the limit rod 46, the limit hole 47, the arrangement of the socket 48 and the second plug rod 49, when the block 41 is engaged in the socket 43, the push block 45 is pushed so that the limiting rod 46 is inserted into the inside of the limiting hole 47, which can limit the block 41 and prevent the block 41 from being accidentally touched and causing its contraction. When the limiting rod 46 is inserted into the limiting hole 47, the second plug rod 49 is inserted into the socket 48 until it is connected with the bolt 25, thereby improving the stability of the limiting rod 46 in the limiting hole 47.

[0048] In this embodiment, if Figure 1-Figure 10 As shown, the working process of a lithium iron phosphate power battery packaging device provided in this embodiment is as follows:

[0049] When packaging the battery, the battery shell 3 will first be placed on the conveying device 2 so that it can be conveyed on the device body 1. When the battery box is installed inside the battery shell 3, the multiple first electric telescopic rods 5 are first started to contract to drive the connecting plate 6 to descend until the second tooth plate 15 is sleeved on the outside of the battery shell 3, and then the driving motor 13 is started to drive the fourth gear 14 to rotate. Due to the connection relationship between the fourth gear 14 and the third gear 12, the third gear 12 will also rotate when the fourth gear 14 rotates.

[0050] The rotation of the third gear 12 can drive the screw rod 11 to rotate, and the rotation of the screw rod 11 can drive the first tooth plate 10 to move on the connecting plate 6. Since the first tooth plate 10 is in a meshing relationship with the multiple second gears 8, the first tooth plate 10 can drive the two first gears 7 to rotate relative to each other during the movement. When the two first gears 7 rotate relative to each other, they can drive the two second tooth plates 15 to move closer to or away from each other. Therefore, the spacing of the clamping claws 16 can be adjusted to clamp and fix the battery casing 3 to prevent it from shaking. The advantage of the adjustable spacing of the clamping claws 16 is that it can be suitable for clamping battery casings 3 of different specifications. The advantage of this structure is that it can prevent the battery cell from moving or dislocating during the packaging process, and prevent the instability of the packaging process from increasing the difficulty and cost of packaging.

[0051] In summary, in the present embodiment, according to a lithium iron phosphate power battery packaging device of the present embodiment, the protective shell 17, the heat dissipation holes 18 and the inspection cover 19 are arranged to protect the drive motor 13 and prevent the drive motor 13 from being damaged by accidental contact. The heat dissipation holes 18 can dissipate the heat generated by the operation of the drive motor 13 to prevent the internal heat accumulation of the protective shell 17 from causing the drive motor 13 to fail. Opening the inspection cover 19 can facilitate personnel to inspect the drive motor 13 without disassembling the protective shell 17, thereby saving personnel's working time. Through the arrangement of the first magnetic ring 20 and the second magnetic ring 21, the two can attract each other to fix the inspection cover 19 on the protective shell 17 to prevent it from falling off. Due to the characteristics of the first magnetic ring 20 and the second magnetic ring 21, the inspection cover 19 can be opened by directly pulling it without tools, thereby saving personnel time to open the inspection cover 19.

[0052] By setting the first fixed frame 22, the connecting hole 23, the first plug rod 24, the bolt 25 and the protrusion 26, after the first plug rod 24 is inserted into the interior of the connecting hole 23, the first plug rod 24 is rotated to adjust the angle of the bolt 25 to be perpendicular to the angle of the connecting hole 23, and the second toothed plate 15 can be fixed inside the first fixed frame 22 to prevent it from falling off. The first plug rod 24 is rotated to adjust the angle of the bolt 25 to be consistent with the connecting hole 23, and the first plug rod 24 can be pulled out, so as to facilitate the disassembly and replacement of the clamping claw 16 when it is damaged. The multiple protrusions 26 set at the other end of the first plug rod 24 can make it convenient for people to prevent their hands from slipping when rotating the first plug rod 24, thereby facilitating the installation and disassembly of the first plug rod 24.

[0053] By setting the slide groove 27 and the slider 28, the friction between the second tooth plate 15 and the connecting plate 6 can be reduced, so that the slider 28 can slide more smoothly inside the slide groove 27, which can not only reduce the wear between the second tooth plate 15 and the connecting plate 6, but also improve the working efficiency of the clamping structure 4. By setting the telescopic legs 29 and the universal wheels 30, when the device body 1 needs to move, the multiple telescopic legs 29 are started to retract at the same time until the universal wheels 30 touch the ground, and the device body 1 can be shifted under the rolling of the multiple universal wheels 30. After the device body 1 moves, the telescopic legs 29 are started to extend so that the ground contacts the ground, which can make the universal wheels 30 leave the ground and be suspended in the air. Under the support of the multiple telescopic legs 29, the stability of the device body 1 can be ensured, thereby saving the time for people to carry the device body 1.

[0054] Through the arrangement of the material transport trolley 31, the second electric telescopic rod 32 and the placement box 33, when the battery pack is packaged, it will be transported to one end of the conveying device 2, and then the material transport trolley 31 will move to one end of the conveying device 2, and the second electric telescopic rod 32 will be started to extend to drive the placement box 33 to lift it upward so that it is at the same level as the conveying device 2. The packaged battery pack can enter the interior of the placement box 33, and then be transported to the next work area by the material transport trolley 31. Automated handling can save labor.

[0055] Through the arrangement of the through hole 34, the fixing frame 35, the third electric telescopic rod 36 and the suction cup 37, when the packaged battery shell 3 enters the interior of the placement box 33, multiple third electric telescopic rods 36 are started at the same time to drive the suction cup 37 to move until it is adsorbed on the battery shell 3, which can improve the stability of the battery shell 3, thereby preventing the battery shell 3 from falling due to inertia when the material transport cart 31 moves.

[0056] Through the arrangement of the fixing block 38, the mounting hole 39, the spring 40, the clamping block 41, the second fixing frame 42 and the clamping hole 43, when the fixing block 38 is inserted into the second fixing frame 42, the clamping block 41 will be squeezed and contracted to the inside of the mounting hole 39. When the clamping block 41 moves to the position of the clamping hole 43, the clamping block 41 will pop out and engage in the inside of the mounting hole 39 under the elastic action of the spring 40, thereby fixing the fixing block 38 in the inside of the second fixing frame 42 to prevent it from falling off.

[0057] The staff presses multiple blocks 41 at the same time to shrink them to the inner side of the second fixed frame 42, and can take the fixed block 38 out of the second fixed frame 42, so as to facilitate the disassembly and replacement of the placement box 33 when it is damaged. Through the setting of the limiting plate 44, the pushing block 45, the limiting rod 46, the limiting hole 47, the plug hole 48 and the second plug rod 49, when the block 41 is engaged in the card hole 43, the pushing block 45 is pushed so that the limiting rod 46 is inserted into the inside of the limiting hole 47, which can limit the block 41 and prevent the block 41 from being accidentally touched and causing its contraction. When the limiting rod 46 is inserted into the limiting hole 47, the second plug rod 49 is inserted into the plug hole 48 until it is connected with the bolt 25, thereby improving the stability of the limiting rod 46 in the limiting hole 47.

[0058] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0059] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0060] The above description shows and describes several preferred embodiments of the present invention, but as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field. Changes and variations made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
