[0002] Lithium-ion batteries have advantages such as high specific energy, many cycle usage times, and long storage time. They are widely used not only in portable electronic devices (such as mobile phones, digital video cameras, and laptop computers), but also in large and medium-sized electric devices such as electric vehicles, electric bicycles, and electric tools. Therefore, the performance requirements for lithium-ion batteries are getting higher and higher.

[0004] However, there are many batteries and large sizes in the CTP module, and there are no raw materials to restrain the module. Therefore, during the lifting process of the module, it is easy to deform, resulting in poor consistency of the module, and even the situation of cell detachment may occur.

[0125] In the present invention, specifically, each front clamping jaw mechanism 70 includes a front clamping jaw 71, a front clamping jaw fixing screw 72, and a front clamping jaw anti-drop ring 73.

[0126] The front jaw anti - detachment ring 73 is fixed to the left or right rear end of the front - insert - plate mechanism fixing part 32 in the front - insert - plate mechanism 30.

[0127] The front jaw anti - detachment ring 73 is fixedly connected to the upper end of the vertically - distributed front jaw 71 through the front - jaw fixing screw 72.

[0128] Specifically, the front - jaw mechanism 70 is located on the front side of the front - insert - plate mechanism 30.

[0129] Specifically, the front jaw in the front - jaw mechanism 70 is in contact with the front - insert - plate mechanism fixing part 32 in the front - insert - plate mechanism 30.

[0130] In the present invention, specifically, each rear - jaw mechanism 80 includes a rear jaw 81, a rear - jaw fixing screw 82, and a rear - jaw anti - detachment ring 83.

[0131] The rear - jaw anti - detachment ring 83 is fixed to the left or right rear end of the main frame 100.

[0132] The rear - jaw anti - detachment ring 83 is fixedly connected to the upper end of the vertically - distributed rear jaw 81 through the rear - jaw fixing screw 82.

[0133] Specifically, the rear - jaw mechanism 80 is located on the rear side of the rear - insert - plate mechanism 50.

[0134] Specifically, the rear jaw 81 in the rear - jaw mechanism 80 is in contact with the rear - insert - plate mechanism fixing part 52 in the rear - insert - plate mechanism 50.

[0135] In the present invention, specifically, the bottoms of the front jaw 71 and the rear jaw 81 are on the same horizontal plane.

[0136] In the present invention, specifically, the battery module 90 includes a battery - module main body.

[0137] The battery - module main body includes a plurality of batteries arranged separately.

[0138] A battery top cover 93 is provided on the top of the battery - module main body.

[0140] On the two module end - plates 91, at positions corresponding to the front insert - plate 31 in the front - insert - plate mechanism fixing part 32 and the rear insert - plate 51 in the rear - insert - plate mechanism 50, longitudinally - distributed insert - plate insertion grooves are provided.

[0141] The insert - plate insertion grooves are used for inserting the front insert - plate 31 or the rear insert - plate 51.

[0142] It should be noted that for the present invention, the module lifting tool can be connected to a lifting device (such as a crane) through the lifting ring 61. The lifting ring 61 can move on the lifting ring adjusting block 62 to adjust the position following the center of gravity of the lifting tool and the module, so as to keep the lifting tool horizontal.

[0143] For the present invention, the rear plug-in plate mechanism 50 and the rear jaw structure 80 are fixed and non-adjustable. The front plug-in plate mechanism 30 and the front jaw structure 70 can be moved through the progressive mechanism 10. Rotate the rotary handle 11 to move it to the corresponding position. Then lower the lifting tool until the suction cup 41 can contact the battery upper cover 93 on the top of the battery module 90. The front and rear plug-in plate mechanisms are inserted into the module end plate 91 (specifically, the plug-in plate therein is inserted into the groove). At the same time, the suction cup 41 sucks the battery in the battery module, and turn on the existing negative pressure device connected to the suction cup mechanism, so that the suction cup 41 tightly adsorbs the battery in the battery module. Then adjust the front and rear jaws to fix them to the lifting holes (i.e., the grooves where the plug-in plates are inserted) on the module end plate.

[0144] After the front and rear plug-in plate mechanisms are fixed to the module end plate, the extrusion force of the module can be recorded according to the reading of the pressure sensor 21. An alarm value can be set, and when the extrusion force exceeds the limit, an audio alarm is given.

[0145] For the present invention, after all three lifting methods (specifically including: the fixed lifting method of the front and rear plug-in plate mechanisms and the module end plate, and the lifting of the battery in the battery module by the suction cup) are fixed in place, the battery module can be lifted to perform the operation of putting the module into the box.

[0146] In summary, compared with the prior art, the multifunctional lifting tool for a battery module provided by the present invention has a scientific structural design, can realize the lifting operation of a battery module (such as an existing CTP battery module), prevent the module from deforming during lifting, and avoid the situation of battery detachment, which has great practical significance.

[0147] By applying the present invention, starting from the lifting method, three lifting methods can be used simultaneously to prevent the module from deforming during lifting. Compared with the current traditional lifting tools, the lifting safety of the present invention for the module is greatly increased. Using the suction cup to suck the battery can effectively prevent the module from deforming during lifting.

[0148] For the present invention, the module lifting tool uses three lifting methods to lift the module. Each of the three methods can complete the lifting alone, and multiple methods can be used simultaneously, greatly increasing the safety. The suction cup lifting method can further ensure that the module does not deform and the battery does not fall off during lifting.

[0149] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
