Referring to fig. 1, an embodiment of the present application provides a rapid assembly process for a rechargeable lithium battery, including the following steps:
s1, preparing a battery cell assembly 10, a circuit board assembly 20 and a shell 30: the battery pack 10 is provided with a positive terminal 11 and a negative terminal 12, the positive terminal 11 is welded with a first conductive piece 13, and the negative terminal 12 is arranged around the first conductive piece 13; the circuit board assembly 20 has a second conductive member 21 and a third conductive member 22, which can be used as a positive electrode and a negative electrode, respectively;
s2, assembling the electric core assembly 10 and the circuit board assembly 20: placing circuit board assembly 20 at one end of electric core assembly 10, detachably connecting first conductive piece 13 and second conductive piece 21, and making third conductive piece 22 abut against negative end 12 of electric core assembly 10;
s3: packaging: the above-mentioned assembled electric core assembly 10 and circuit board assembly 20 are enclosed in the outer casing 30, and the outer end 211 of the second conductive member 21 of the circuit board assembly 20 is protruded out of the outer casing 30.
In this application, but set up respectively on electric core subassembly 10 and circuit board assembly 20 and can be each other just connect with the electrically conductive piece of burden connection, and adopt the mode that can dismantle connection and butt to realize the electricity and connect and the physical connection between the electrically conductive piece that corresponds, this kind of equipment mode can realize the fast assembly of lithium cell, improves production efficiency greatly, and the equipment quality obtains guaranteeing, reduction in production cost on the whole.
Further, referring to fig. 2 and 3, in the step S2, the detachable connection between the first conductive member 13 and the second conductive member 21 is a threaded connection, and through the threaded connection, not only the electrical connection between the positive electrode and the negative electrode is achieved, but also the physical fixation between the electric core assembly 10 and the circuit board assembly 20 is achieved.
In step S1, when the electrical core assembly 10 is prepared, the electrical core assembly 10 can be manufactured in a conventional manner, and the internal structure of the electrical core assembly 10 can be arbitrarily adjusted according to actual needs, for example, the electrical core assembly 10 can include a casing 14 and one or more electrical cores (not shown in the figure) located in the casing 14, and when there are a plurality of electrical cores, the electrical cores can be electrically connected in parallel or in series. In the present application, the external structure of the electrical core assembly 10 is mainly modified to realize the detachable connection with the circuit board assembly 20. Specifically, after the electric core assembly 10 is manufactured, the positive electrode and the negative electrode of the electric core or the electric core assembly 10 are led out of the casing to form the positive electrode terminal 11 and the negative electrode terminal 12. In this application, the positive terminal 11 is located at the very center of the housing 14, and the negative terminal 12 is surrounded by the positive terminal 11, with an insulation treatment therebetween. The first conductive member 13 includes a metal plate 131 welded to the positive terminal 11 and a metal screw 132 protruding outward from the center of the metal plate 131. When the circuit board assembly 20 is prepared, the circuit board assembly 20 includes the circuit board 23, the second conductive member 21 penetrates through the center of the circuit board 23, the inner end of the second conductive member 21 located inside the circuit board 23 is a metal nut 212, and the outer end 211 extends outside the circuit board 23. Thus, at the time of assembly in step S2, the metal screw 132 is screwed into the metal nut 212, so that the electrical connection and the physical connection of the electric core assembly 10 and the positive electrode of the circuit board assembly 20 are achieved.
Of course, the positions of the two parts can be interchanged by adopting a threaded connection mode. For example, the metal screw 132 on the first conductor 13 is changed into a metal nut, and the inner end of the second conductor 21 is changed into a metal screw; in the step S2, during assembly, the metal screw is screwed into the metal nut.
The contact between the negative end 12 of the core assembly 10 and the third conductive member 22 can be achieved in different ways while the metal screw is connected to the metal nut.
As one embodiment, in step S1, when the circuit board assembly 20 is prepared, the third conductive member 22 includes an elastic member 221 having one end soldered to an inner edge of the circuit board 23. Specifically, the elastic element 221 is a spring-type thimble, and the number of the spring-type thimbles may be one or multiple, and when the number of the spring-type thimbles is multiple, the multiple spring-type thimbles are uniformly distributed along the periphery of the second conductive element 21. In step S2, during assembly, the other end of the one or more spring-loaded pins abuts against the negative terminal 12 of the core assembly 10, so that the electrical connection between the negative terminals of the core assembly 10 and the circuit board assembly 20 is realized. Moreover, the mode of adopting this kind of spring also makes the butt effect better.
In another embodiment, only one elastic member 221, i.e. a spring, may be provided, and the spring is sleeved outside the second conductive member 21, and a first insulating member is provided between the spring and the second conductive member 21, i.e. the spring is sleeved on the first insulating member. Because the negative pole end of the electric core assembly 10 is annularly arranged along the outer side of the positive pole end, the spring sleeved on the periphery of the second conductive piece 21 corresponds to the negative pole end, in the S2 assembling step, the two can be abutted better, and the electric connection effect is better.
Specifically, in step S1, when the circuit board assembly 20 is prepared, the circuit board assembly 20 further includes a charging port 231 provided on the circuit board 23; when the shell 30 is prepared, an opening 31 is reserved on the shell 30; in step S3, during packaging, the charging port 231 is exposed from the opening 31, so as to be connected to an external power source for charging.
Specifically, in the step S1, a second insulation sheet 40 is prepared, the size of the second insulation sheet 40 matches the size of the end face of the circuit board assembly 20, and a central hole 41 is formed in the middle of the second insulation sheet; in step S3, before the electric core assembly 10 and the circuit board assembly 20 are assembled into the outer shell 30, the second insulating sheet 40 is sleeved on the circuit board assembly 20, and the end of the second conductive member 21 of the circuit board assembly 20 extends out of the central hole 41.
Specifically, in step S1, in preparing the housing 30, one end face of the housing 30 has a flange 32, the flange 32 has a center hole 33 at the center, and the other end of the housing 30 is hollow; in step S3, the above-mentioned assembled electric core assembly 10, circuit board assembly 20 and second insulation sheet 40 are inserted from one hollow end until the second insulation sheet 40 abuts against the flange 32, and the outer end 211 of the second conductive member 21 extends out of the central hole 33, and then the other end of the outer shell 30 is sealed, thereby completing the rapid assembly of the rechargeable lithium battery.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application.
