Abstract

The invention provides a bolt sequential tightening tool applied to a lithium battery and belongs to the technical field of lithium battery assemblies. The bolt sequential tightening tool applied to the lithium battery comprises a shell, two guide pins, at least four supporting blocks, a plurality of indicator lamps, a plurality of photoelectric sensor groups, a plurality of label groups and a PLC; the shell is longitudinally provided with a plurality of first light holes, a plurality of second light holes and two third light holes; the side edge of the shell is provided with at least four notches; the periphery of each third light hole is circularly provided with a plurality of threaded holes; the two guide pins are inserted into the corresponding third light holes and are locked to the corresponding threaded holes by bolts; the at least four supporting blocks are locked to the side edge of the shell through the notches respectively; the plurality of indicator lamps are arranged in the corresponding second light holes; the plurality of photoelectric sensor groups are arranged at the periphery of the first light holes respectively; the plurality of label groups are arranged at theperiphery of the first light holes respectively; and the PLC is electrically connected with the indicator lamps and the photoelectric sensor groups. The bolt sequential tightening tool has the advantages that reminder on a sequence and a torque of the bolt tightening process, whether all the bolts are screwed in or not and the bolt screwing process are achieved, and the qualified rate of assemblyof the lithium battery is greatly increased.

Description

technical field

[0001] The invention relates to the technical field of lithium battery assembly, in particular to a sequential tightening tool for bolts applied to lithium batteries. Background technique

[0002] Lithium batteries need to be assembled after production is completed. During the assembly process, the screwing depth and torque of bolts directly affect the assembly quality of lithium batteries, and there are many parts that need to be tightened with bolts. Traditionally, there are two methods of robot tightening and manual tightening. Due to the high cost of robots, small-scale production workshops usually use manual tightening. However, the traditional manual tightening method has the following disadvantages:

[0003] 1. There is no prompt for the order of bolt tightening, but there are a large number of bolts to be tightened, which makes the employees tighten in disorder, which is not standardized; 2. There is no prompt for the torque of bolt tightening, which...

Embodiment Construction

[0029] Please refer to Figure 1 to Figure 5 As shown, a preferred embodiment of a bolt sequence tightening tool 100 applied to a lithium battery in the present invention includes:

[0030] An aluminum shell 1 is longitudinally provided with a plurality of first light holes 11 for tightening bolts, a plurality of second light holes 12 and two third light holes 13 for installing indicator lights 4, and the side is provided with at least Four notches 14; a plurality of threaded holes 16 are arranged around the third light hole 13;

[0031] Two guide pins 2 are inserted into the third light hole 13, and locked on the threaded hole 16 by bolts; the guide pin 2 is used to guide the tightening tool 100 so that it is compatible with the lithium battery 9 to be assembled. carry out alignment;

[0032] At least four support blocks 3 are locked to the side of the housing 1 through the notches 14; the support blocks 3 are used to support the tightening tool 100 on the lithium battery 9...
