Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery module assembly, and in particular to a clamping device and method for packaging lithium battery modules. Background Art

[0002] Lithium batteries are important energy storage components in the fields of electric vehicles, energy storage power stations, etc. However, lithium battery modules are susceptible to external environmental influences during transportation, storage and installation. In particular, vibration and impact may cause damage to the internal structure of the battery, thereby affecting battery performance and even causing safety issues. Therefore, lithium batteries need to be packaged before transportation. When packaging, the lithium battery needs to be clamped and fixed by a clamping device to facilitate subsequent packaging.

[0003] The Chinese utility model patent with announcement number CN221367941 U discloses a lithium battery module packaging device, including an operating table and an auxiliary extrusion unit. Through the setting of the auxiliary extrusion unit, when packing lithium battery modules of different heights, the height of the clamping plate can be adaptively adjusted, so that even if the extrusion unit presses against the lower side of the clamping plate, the upper side of the clamping plate can also clamp the lithium battery module under the action of the auxiliary extrusion unit, thereby making the upper and lower parts of the lithium battery module evenly stressed, thereby ensuring the clamping of the lithium battery module and improving the efficiency and quality of lithium battery module packaging. Although the device can clamp the lithium battery module, before the device clamps the lithium battery module, after the personnel complete a packing, they need to remove the packed lithium battery module and then manually place the lithium battery module for packaging. Therefore, the packaging is difficult and inefficient, and the personnel need to manually pull the strapping tape back and forth for packaging, which further increases the difficulty of lithium battery module packaging and reduces the efficiency of lithium battery module packaging.

[0004] The Chinese utility model patent with the announcement number CN219728628U discloses a clamping device for packing lithium battery modules, including two clamping parts and a driving part, the two clamping parts are arranged in parallel, the driving part is connected to one of the clamping parts to drive the clamping part to move relative to the other clamping part, the two clamping parts each include a mounting plate, a plurality of fixings and a plurality of adjusting parts, the two mounting plates are arranged in parallel, each fixing part is perpendicular to the mounting plate; each adjusting part is respectively connected to two adjacent fixings; the clamping device for packing lithium battery modules also includes a top limiter, and the top limiter is arranged above the two clamping parts. When the device is working, after the personnel completes a packing, they also need to remove the packed lithium battery module and then manually place the lithium battery module for packing, which cannot be operated in a flow-line manner, and the packing difficulty is high and the packing efficiency is low. The personnel also need to manually pull the packing belt back and forth for packing, which further increases the difficulty of packing lithium battery modules and reduces the packing efficiency of lithium battery modules. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a clamping device and method for packing lithium battery modules. By providing a conveying member that can be tilted and has a conveying channel and a clamping member with a clamping space, when the conveying member is tilted, the lithium battery module on the conveying member slides onto the clamping member, and the staff does not need to remove the packed lithium battery modules and then place the lithium battery modules one by one, thereby improving the packing efficiency of the lithium battery modules. In order to achieve the above purpose, the present invention is implemented through the following technical solutions:

[0006] In a first aspect, the present invention provides a clamping device for packaging a lithium battery module, comprising:

[0007] Supporting members;

[0008] A conveying member, comprising a conveying unit and a telescopic unit, wherein the conveying unit has a conveying channel for conveying lithium battery modules along a preset path, one end of the conveying unit is hinged to the supporting member, and the other end is connected to the supporting member through the telescopic unit to realize lifting of the end;

[0009] The clamping member is located near the hinged side of the conveying unit and the supporting member, and includes a first rotating plate and a second rotating plate, and a clamping space for clamping the lithium battery module is formed therebetween. The lithium battery module can enter the clamping space through the conveying channel.

[0010] As a further implementation, the conveying unit includes a support frame, and a through slot of the support frame and a plurality of guide rollers arranged in the through slot together form the conveying channel.

[0011] As a further implementation method, the telescopic unit includes a first push rod, one end of which is hinged to the conveying unit, and the other end is a telescopic end provided with a first moving rod, two limit rods are symmetrically provided at the end of the first moving rod, and the supporting member has a guide groove that cooperates with the limit rod.

[0012] As a further implementation, side grooves are provided on both sides of the guide groove, and the limiting rod extends into the side grooves.

[0013] As a further implementation, the first rotating plate is configured with a second push rod for driving the first rotating plate to rise and fall, and a motor for driving the first rotating plate to rotate.

[0014] As a further implementation method, a plurality of bottom holes and elastic limiting units are arranged therein on the clamping surface of the first rotating plate, and the elastic limiting unit includes a spring and a bottom rod connected thereto, the spring is installed in the bottom hole, and the bottom rod partially extends into the bottom hole, and the area where the elastic limiting unit is provided can completely cover the lithium battery module.

[0015] As a further implementation, the outer diameter of the first rotating plate is smaller than the outer diameter of the second rotating plate.

[0016] As a further implementation, rubber pads are provided on the clamping surfaces of the first rotating plate and the second rotating plate.

[0017] As a further implementation, the clamping member further includes a base plate, and the second rotating plate is rotatably connected to the base plate.

[0018] In a second aspect, the present invention provides a working method of the clamping device for packaging lithium battery modules according to the first aspect, comprising the following steps:

[0019] The lithium battery module to be packaged is placed on the conveying unit. The telescopic unit drives one end of the conveying unit to rise so that the conveying unit is tilted, and then the lithium battery module on the conveying unit slides to the second rotating plate. The first rotating plate and the second rotating plate clamp the lithium battery module together. The rotation of the first rotating plate drives the lithium battery module and the second rotating plate to rotate together. The staff wraps the packing tape around the lithium battery module for packaging, and removes it after packaging. The subsequent lithium battery modules to be packaged automatically slide to the second rotating plate until all lithium battery modules are packaged.

[0020] The beneficial effects of the present invention are as follows:

When the conveying member is tilted, the lithium battery module on the conveying member slides onto the clamping member, the lithium battery module is clamped by the clamping member, and the lithium battery module is driven to rotate by the clamping member, so that the staff can pack the lithium battery modules conveniently. After packing, the staff removes the packaged lithium battery modules, and the lithium battery modules on the conveying part can automatically slide onto the clamping member, so that the staff does not need to remove the packaged lithium battery modules and then place the lithium battery modules one by one, thereby improving the packing efficiency of the lithium battery modules.

The clamping surface of the first rotating plate of the present invention is provided with a plurality of elastic limiting units, and the area provided with the elastic limiting units can completely cover the lithium battery module. When the lithium battery module is clamped by the first rotating plate, the first rotating plate will synchronously drive the plurality of elastic limiting units to move together until the bottom rod contacts the top of the lithium battery module. When the lithium battery module contacts the bottom rod, the bottom rod compresses the spring, and the bottom rod that is not squeezed limits the lithium battery module, thereby making the lithium battery module more stable when being packaged, avoiding side slipping of the lithium battery module when being packaged, and improving the stability of the lithium battery module when being packaged.

DETAILED DESCRIPTION

[0038] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0039] Embodiment 1

[0040] In a typical embodiment of the present invention, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a clamping device for packaging lithium battery modules includes a supporting member 1, a conveying member 2 and a clamping member 3, wherein the conveying member 2 and the clamping member 3 are both installed above the supporting member 1.

[0041] like Figure 5 and Figure 6 As shown, the support member 1 includes a base 11, a foot 12, a guide groove 13, a side groove 14 and a bracket 15. The top of the base 11 is symmetrically sunken to form two guide grooves 13, and the inner wall of the guide groove 13 is symmetrically formed along its length direction to form two side grooves 14, and the top of the base 11 is fixedly connected to the bracket 15.

[0042] like Figure 6 and Figure 7 As shown, the conveying member 2 includes a conveying unit and a telescopic unit. The conveying unit has a conveying channel for conveying lithium battery modules along a preset path. One end of the conveying unit is hinged to the support member 1, and the other end is connected to the support member 1 through the telescopic unit to achieve the lifting of the end. After the end is lifted, the conveying unit is tilted as a whole, and the lithium battery module placed on the conveying unit can slide from the high end to the low end.

[0043] The conveying unit 2 includes a support frame 21, a through slot 22 of the support frame 21 and a plurality of guide rollers 23 arranged in the through slot 22 together form a conveying channel. The through slot 22 is arranged along the direction of the conveying channel. A plurality of guide rollers 23 are rotatably connected in the through slot 22 along its length direction. The support frame 21 of the conveying unit is hinged to the bracket 15 of the support member 1.

[0044] The telescopic unit includes a first push rod 24, one end of which is hinged to the support frame 21 of the conveying unit, and the other end is a telescopic end provided with a first moving rod 25, and two limit rods 26 are symmetrically provided at the end of the first moving rod 25, and the support member 1 has a guide groove 13 to cooperate with the limit rod 26. In this embodiment, the first push rod 24 is an electric push rod. It can be understood that in some other embodiments, other driving methods can also be used, not limited to the electric push rod in this example.

[0045] Side grooves 14 are provided on both sides of the guide groove 13, and the limiting rods 26 extend into the side grooves 14. The first push rod 24 drives the first moving rod 25 to move, and the limiting rod 26 on the first moving rod 25 cooperates with the guide groove 13 and the side groove 14, so that the first push rod 24 rotates around the support frame 21, and then drives the support frame 21 to rotate around the bracket 15, so as to achieve the purpose of tilting the support frame 21. At this time, the lithium battery module on the support frame 21 slides under the action of the guide roller 23.

[0046] like Figure 8 and Fig. 9 As shown, the clamping member 3 is located near the hinged side of the conveying unit and the supporting member 1, and includes a first rotating plate 38 and a second rotating plate 39, and a clamping space for clamping the lithium battery module is formed therebetween. The lithium battery module can enter the clamping space through the conveying channel.

[0047] During operation, the lithium battery modules to be packaged are placed on the conveying part, and the telescopic part is extended and retracted to make the conveying part rotate around the supporting member 1, thereby making the conveying part tilt, so that the lithium battery modules on the conveying part slide onto the clamping member 3, and the lithium battery modules are clamped by the clamping member 3, and the clamping member 3 is rotated relative to the supporting member 1 to drive the lithium battery modules to rotate, so that the staff can pack the lithium battery modules conveniently, and after packaging, the staff removes the packaged lithium battery modules, and the lithium battery modules on the conveying part can automatically slide onto the clamping member 3, so that the staff do not need to remove the packaged lithium battery modules and then place the lithium battery modules one by one, thereby improving the packaging efficiency of the lithium battery modules.

[0048] The clamping member 3 also includes a top plate 31 and a base plate 32. The bottom of the top plate 31 is fixedly connected to the top of the base 11. The top of the top plate 31 is fixedly connected to the base plate 32. An L-shaped bracket 33 is fixedly connected to one side of the top of the base plate 32. The top of the base plate 32 is rotatably connected to a second rotating plate 39, which is located on one side of the top frame 33. A reinforcing plate 34 is fixedly connected to one side of the top frame 33. A second push rod 35 is fixedly connected to the top of the top frame 33. The telescopic end of the second push rod 35 is connected to a second moving rod 36. The bottom of the second moving rod 36 is fixedly connected to a motor 37, and the output end of the motor 37 is connected to a first rotating plate 38. The second push rod 35 drives the first rotating plate 38 to rise and fall vertically, and the motor 37 drives the first rotating plate 38 to rotate. In this embodiment, the second push rod 35 is an electric push rod. It can be understood that in some other embodiments, other driving methods can also be used, not limited to the electric push rod in this example.

[0049] The outer diameter of the first rotating plate 38 is smaller than the outer diameter of the second rotating plate 39 , which facilitates the subsequent packaging operation.

[0050] Rubber pads 310 are disposed on the clamping surfaces of the first rotating plate 38 and the second rotating plate 39 to increase the friction force on the lithium battery module and provide buffer protection.

[0051] like Fig.10 , Fig.11 , Fig.12 As shown, the clamping surface of the first rotating plate 38 is provided with a plurality of bottom holes 312 and elastic limiting units arranged therein, the elastic limiting unit includes a spring 313 and a bottom rod 311 connected thereto, the spring 313 is installed in the bottom hole 312, the bottom rod 311 partially extends into the bottom hole 312, and the area provided with the elastic limiting unit can completely cover the lithium battery module.

[0052] When the lithium battery module is clamped by the first rotating plate 38, the first rotating plate 38 will synchronously drive the multiple elastic limiting units to move together until the bottom rod 311 contacts the top of the lithium battery module. When the lithium battery module contacts the bottom rod 311, the bottom rod 311 compresses the spring, and the bottom rod 311 that is not squeezed limits the lithium battery module, thereby making the lithium battery module more stable when packaged, avoiding side slippage of the lithium battery module when packaged, and improving the stability of the lithium battery module when packaged.

[0053] Embodiment 2

[0054] This embodiment provides a working method of the clamping device for packaging lithium battery modules according to the first embodiment, comprising the following steps:

[0055] Place the base 11 at the position where it is needed. After the base 11 is placed stably, the base 11 is made more stable by the cooperation of the foot 12. Then, the lithium battery module to be packaged is placed on the support frame 21 of the conveying unit. The first push rod 24 of the telescopic unit drives one end of the support frame 21 of the conveying unit to rise so as to tilt the support frame 21 of the conveying unit, thereby allowing the lithium battery module on the support frame 21 of the conveying unit to slide onto the second rotating plate 39. The first rotating plate 38 and the second rotating plate 39 jointly clamp the lithium battery module. The first rotating plate 38 rotates and drives the lithium battery module and the second rotating plate 39 to rotate together. The staff wraps the strapping tape around the lithium battery module for packaging, and removes it after packaging. The subsequent lithium battery modules to be packaged automatically slide onto the second rotating plate 39 until all lithium battery modules are packaged.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
