[0029] A protection and fixing tooling for high-voltage copper bars of a power lithium battery. This fixing tooling cooperates with the copper bar installation position of the battery pack to achieve the positioning and installation of the copper bars, and includes:

[0030] The main cover panel 1 and the sub-cover panel 2 connected in a split manner;

[0031] A plurality of rectangular card slots 11 are penetrated on the surface of the main cover panel 1;

[0032] A transparent plate is installed at the open end of the rectangular card slot 11;

[0033] A light strip 3 is installed inside the rectangular card slot 11;

[0034] The copper bar passes through the rectangular card slot 11 and is pre-tightened and fixed, and each group of copper bars is spaced apart by the corresponding rectangular card slot 11 to prevent cross-connection installation.

[0035] The main cover panel 1 and the sub-cover panel 2 can be used separately or in combination;

[0036] Round holes 4 are respectively opened at the joint parts of the main cover panel 1 and the sub-cover panel 2;

[0037] The nylon tie passes through the round hole 4 and is tied to realize the combined use of the main cover panel 1 and the sub-cover panel 2.

[0038] The outer surfaces of the main cover panel 1 and the sub-cover panel 2 are made of insulating and fireproof materials.

[0039] Specifically, a protection and fixing tooling for high-voltage copper bars of a power lithium battery has a main cover panel 1 and a sub-cover panel 2. The main cover panel 1 and the sub-cover panel 2 can be used separately or together. Round holes 4 are respectively opened on the main cover panel 1 and the sub-cover panel 2. When used in combination, the nylon tie is used to pass through the round hole 4 to tie the two tightly. Among them, according to the installation sequence of the copper bars, a plurality of rectangular card slots 11 are penetrated on the main cover panel 1. When in use, the copper bar passes through the gap of the rectangular card slot 11 and then is fixed. A transparent plate is installed on the surface of the rectangular card slot 11, and the light strip 3 is also installed on the inner circumference of the rectangular card slot 11 and is located inside the transparent plate.

[0040] Among them, the outer surfaces of both the main cover panel 1 and the sub-cover panel 2 are coated with insulating and fireproof materials.

[0041] Further, according to the actual assembly state of the power battery pack, the fixing tooling can be divided into two parts, the front part and the rear part, for combined use. When only the copper bars at the front end of the battery pack need to be assembled, such as replacing a single copper bar, only the main cover panel 1 can be used to pre-tighten or fasten the copper bars. When only the copper bars at the rear end of the battery pack need to be assembled, only the parts of the main cover panel 1 and the sub-cover panel 2 can be used to achieve the function of preventing misassembly of the copper bars. When all the copper bars of the whole battery pack need to be assembled, the main cover panel 1 is placed at the front end of the battery pack, and the sub-cover panel 2 is placed at the rear end of the battery pack. A round hole 4 is provided at the connecting part of the main cover panel 1 and the sub-cover panel 2. After using a nylon tie to pass through the round hole 4 and bundle the main cover panel 1 and the sub-cover panel 2, they can be used in combination.

[0042] When positioning and installing the copper bars, according to the installation sequence of the copper bars, the copper bars are passed through the gaps of the rectangular card slots 11 of the main cover panel 1 and pre-tightened and fixed, corresponding to the copper bar installation positions of the battery pack respectively. The intervals between the rectangular card slots 11 play a role in preventing misassembly of the copper bars, preventing copper bar short circuits caused by copper bar cross-connection. During the installation process, the installation positions of the copper bars are confirmed by the lengths of the rectangular card slots 11. A light strip 3 is provided on the main cover panel 1, which is convenient for positioning and fixing the present utility model in the battery pack box body, realizing the positioning of the copper bars, ensuring the fixation of the copper bars in the battery box body, avoiding shaking interference, and at the same time solving the problem of fixing special-shaped / multi-bent copper bars.

[0043] (This tooling is used in combination with an artificial intelligence robot) Embodiment 1:

[0044] First, in the present application, the light strip 3 has a light strip control system, and the light strip control system can regulate the color change of the light strip. Specifically, during actual assembly, the light strip can be set with a reasonable lighting sequence according to the installation sequence of the copper bars. For example, the lights are divided into three colors. When the yellow light is on, it means that the installation position of the copper bar is to be operated. When the green light is on, it means that the installation position of the copper bar is operated correctly. When the red light is on, it means that there is an operation error (or omission) at the position of the copper bar. According to the installation sequence, the lights at the corresponding installation positions light up in turn.

[0045] Along with the lighting sequence of the light strip, it can work together with an artificial intelligence robot equipped with light recognition or infrared receiving and transmitting functions. Before pre-tightening / fastening the copper bars, confirm the high-voltage part of the battery pack where the copper bars are installed this time, the model of the copper bars, and the number of the copper bars. When the robot recognizes the yellow light-on information, it performs the operations of pre-tightening and fastening the copper bar bolts. When the robot recognizes the green light-on information, it detects the torque and then retracts the working arm. When the robot receives the red light-on information, it stops working and alarms. If the robot does not support light recognition or infrared receiving and transmitting functions, the light strip information can be output as a signal recognizable by the robot and transmitted through the robot connection.

[0046] This tooling can be connected to an intelligent robot to achieve the function of automatically controlling the copper bar assembly, realizing the intelligence of the production line while avoiding errors in copper bar assembly, saving labor and improving efficiency.

[0047] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
