In fact, the left milling assembly 200, the right milling assembly 300 and the upper milling assembly 400 can be milling mechanical arms or follow-up mechanisms that cooperate with milling assemblies, which can respectively mill the left side, right side and upper side of the battery module to mill off the end plates on the left and right sides of the battery module and the upper busbar; the clamp assembly 500 can be a mechanical clamp for clamping the battery module, etc., for clamping the battery module and fixing the position of the battery module, so as to cooperate with the left milling assembly 200, the right milling assembly 300 and the upper milling assembly 400 to disassemble the battery module; Figure 4 As shown, the transverse moving assembly 600 can be a single-axis follow-up moving assembly, which can drive the clamp assembly 500 to move forward and backward so that the battery module fixed on the clamp assembly 500 enters or leaves the processing position in the frame 100.

[0045] The specific working principle of the battery module milling center of the utility model is as follows: in the initial state, the transverse movement component 600 drives the clamp component 500 to move to the front side of the frame 100, and clamps the battery module to be milled on the clamp component 500 on the front side of the frame 100; the transverse movement component 600 drives the battery module fixed on the clamp component 500 to move backward to the processing position of the frame 100, and the left milling component 200, the right milling component 300 and the upper milling component 400 work simultaneously, and respectively mill the left side, the right side and the upper side of the battery module to mill off the end side plates on the left and right sides of the battery module and the upper bus; after milling, the transverse movement component 600 drives the battery module fixed on the clamp component 500 to move forward to the front side of the frame 100, removes the milled battery module, and enters the next working cycle.

[0046] The battery module milling center of the utility model cooperates with the frame 100, the left milling assembly 200, the right milling assembly 300, the upper milling assembly 400, the clamp assembly 500 and the transverse movement assembly 600 to simultaneously mill the three sides of the battery module without adjusting the orientation of the battery module, thereby shortening the disassembly time of the battery module and improving the disassembly efficiency.

[0047] Specifically, Figure 2As shown, the frame 100 is preferably provided with a left opening 110, a right opening 120, an upper opening 130, a front opening 140 and a rear opening 150.

[0049] It is worth mentioning that in the process of disassembling the battery module, the battery may be damaged, causing battery leakage or short circuit, causing the battery core to burn, and causing a fire accident. Figure 1 , Figure 2 , Figure 5 , Figure 7 , Figure 8 and Fig.10As shown, the battery module milling center of the utility model preferably also includes an explosion-proof box 700 arranged on the rear side of the frame 100, and the frame 100 is provided with a smoke sensor or / and a temperature sensor for detecting the battery module (in fact, the smoke sensor or / and the temperature sensor can be installed at the frame and located on the upper side of the battery module processing position, and the smoke sensor or / and the temperature sensor are omitted in the accompanying drawings), and the rear opening 150 is provided with a discharge plate 160 that is inclined downward from the front to the back and is used to guide the battery module into the explosion-proof box 700, and the clamp assembly 500 is installed with a discharge assembly 800 that is connected to the smoke sensor or / and the temperature sensor for communication and is used to push the battery module onto the discharge plate 160. In fact, the explosion-proof box 700 can be filled with substances for preventing and extinguishing the combustion of single cells; when the left milling assembly 200, the right milling assembly 300 and the upper milling assembly 400 are milling the battery module in the position frame 100 and fixed on the module assembly, when the smoke sensor and / or the temperature sensor detects that the battery module generates smoke or / and the temperature is too high, an emergency signal is sent out. After receiving the signal, the left milling assembly 200, the right milling assembly 300 and the upper milling assembly 400 stop processing, the clamp assembly 500 releases the clamping of the battery module, the unloading assembly 800 lifts the battery module and the punch clamp assembly 500 flips the unloading plate 160, and introduces it into the explosion-proof box 700 under the guidance of the unloading plate 160, thereby reducing the occurrence of fire accidents.

Before the battery module enters the explosion-proof box 700, the opening and closing cylinder 730 drives the cover body to open; after the battery module enters the explosion-proof box 700, the opening and closing cylinder 730 drives the cover body to close the upper opening 130 of the box body 710, which can prevent the battery module from exploding and splashing to a certain extent.

[0051] In this embodiment, if Figure 5 , Figure 6 and Figure 8As shown, the clamp assembly 500 preferably includes a clamp base 510 installed at the output end of the transverse movement assembly 600, two movable clamps 520 which are symmetrically arranged and connected to the clamp base 510 for left and right sliding, and a clamping drive mechanism 530 installed on the clamp base 510 for driving the two movable clamps 520 to move closer or away from each other. The movable clamp 520 is provided with a front positioning surface 521 for positioning the front side of the battery module, a bottom positioning surface 522 for positioning the lower side of the battery module, and a side positioning surface 523 for positioning the left or right side of the battery module. In fact, the driving mechanism can be a screw rod rotatably connected to the clamp base 510 and a servo motor driving the screw rod to rotate. The screw rod is provided with a first threaded portion and a second threaded portion with opposite rotation directions and the same lead. The two movable clamps 520 are respectively threadedly connected to the first threaded portion and the second threaded portion. The servo motor drives the screw rod to rotate forward and reversely to drive the movable clamp 520 to move so as to clamp the battery module; the front positioning surface 521 can be realized by setting a positioning block, and the side positioning surface 523 and the bottom positioning surface 522 can be realized by setting a positioning groove, thereby realizing the clamping and positioning of the battery module.

[0052] Specifically, Figure 7 and Figure 8 As shown, in the present embodiment, the unloading assembly 800 preferably includes a lifting cylinder 810 for lifting the battery module or clamping the battery module in cooperation with the front positioning surface 521, and a transverse cylinder 820 installed on the clamp assembly 500 and used to drive the lifting cylinder 810 to move forward and backward; when the battery module needs to be lifted, the upper extension of the lifting cylinder 810 retracts and is located at the front of the lower part of the battery module, and the upper extension of the lifting cylinder 810 pushes up to lift the front part of the battery module, and the transverse cylinder 820 drives the lifting cylinder 810 to move backward, so that the battery module continues to flip onto the unloading plate 160, ensuring the transfer of the battery module; when the battery module needs to be clamped, the lifting cylinder 810 is located behind the battery module, and the upper extension of the lifting cylinder 810 pushes up to the top of the bottom surface of the battery module, and the transverse cylinder 820 drives the lifting cylinder 810 to move forward to cooperate with the front positioning surface 521 to clamp the battery module.

[0053] It should be noted that if Figure 1 and Fig. 9As shown, the battery module milling center of the utility model also preferably includes a distance measuring component 900 that is connected to the left milling component 200, the right milling component 300, the upper milling component 400, the fixture component 500 and the traverse component 600.

In fact, the distance between the left end cover plate and the right end cover plate of the battery module on the fixture component 500 can be measured respectively through the two groups of the first distance measuring components 910, so as to control the left milling component 200 and the right milling component 300 to perform more accurate milling; at the same time, since the busbar contour on the upper side of the battery module is relatively duplicated, the distance detection of the busbar is accelerated through the two groups of the second distance measuring components 920, so as to control the upper milling component 400 to perform more accurate milling.

[0054] Specifically, Fig. 9 As shown, the first distance measuring component 910 and the second distance measuring component 920 preferably include a YZ two-axis translation stage 911 and a laser distance measuring sensor 912 installed at the output end of the YZ two-axis translation stage 911.
