[0025] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0026] like Figures 1 to 5 As shown, a battery cell laser scribing streamline includes a placement platform 1 for placing a battery cell 100, a centering and positioning component 2, a limit component 3, an insert 4, a lateral movement module 5 and a laser scribing mechanism 7.

[0027] Specifically, Figure 1 and 2 As shown, the placement surface of the placement platform 1 has a groove 13 that exposes a portion of the bottom surface of the battery cell 100, and the side of the groove 13 is open to facilitate the insertion of the hand 4 along the first direction. In this embodiment, the placement platform 1 includes a bottom plate 11 and at least two placement plates 12 connected to the bottom plate 11 at intervals along the second direction, wherein the bottom plate 11 and the groove 13 are formed between two adjacent placement plates 12. The bottom of the placement platform 1 is connected to a base 9 through a group of columns 8.

[0028] like Figure 2 and 3 As shown, the centering and positioning assembly 2 is used to center and position the battery cell 100 located on the placement platform 1 along a second direction perpendicular to the first direction, and includes two side clamps 21 arranged opposite to each other, a rotating arm 22 and a first driving member 23, wherein the side clamps 21 are connected to a first slide 24 having a slide groove 241, and the first slide 24 is slidably connected to the placement platform 1 along the second direction; both ends of the rotating arm 22 are connected to slide bars 25, and the two slide bars 25 are respectively slidably arranged in two slide grooves 241; the first driving member 23 drives the rotating arm 22 to rotate relative to the placement platform 1. In this embodiment, the first driving member 23 is preferably a servo motor.

[0029] In the centering and positioning assembly 2, the connection position of the side clamping plate 21 on the first slide 24 is adjustable along the second direction. The side clamping plate 21 is provided with a long first adjustment hole, in which a first locking screw is arranged, and the first locking screw is screwed to the first slide 24.

[0030] In the centering and positioning assembly 2 , a first hollow groove is formed on the positioning surface of the side clamping plate 21 to prevent the side clamping plate 21 from being adsorbed and attached to the battery cell 100 , which is not conducive to the separation of the two.

[0031] When in use, driven by the first driving member 23 , the rotating arm 22 rotates, driving the two first slide seats 24 to move toward each other, so that the two side clamping plates 21 move toward each other together to center and position the battery cell 100 .

[0032] like Figure 2 and 3 As shown, the limiting assembly 3 is used to limit the battery cell 100 located on the placement platform 1 along the first direction, and includes a first limiting plate 31, a second slide 32 and a second driving member 33. The second slide 32 is slidably connected to the placement platform 1 along the first direction, and the first limiting plate 31 is connected to the second slide 32; the second driving member 33 drives the second slide 32 to slide. In this embodiment, the second driving member 33 is preferably a cylinder.

[0033] In the limit assembly 3 , the installation position of the first limit plate 31 on the second slide seat 32 is adjustable along the first direction. The first limit plate 31 is provided with a second elongated adjustment hole, in which a second locking screw is arranged, and the second locking screw is screwed to the second slide seat 32 .

[0034] In the limiting assembly 3 , a second hollow groove is formed on the positioning surface of the first limiting plate 31 to prevent the first limiting plate 31 from being adsorbed and attached to the battery cell 100 , which is not conducive to the separation of the two.

[0035] When in use, driven by the second driving member 33 , the first slide seat 32 slides along the first direction relative to the placement platform 1 , so that the first limiting plate 31 pushes the battery cell 100 to move to a preset position along the first direction.

[0036] It should be noted that after the battery cell 100 is placed on the placement platform 1, the battery cell 100 can be positioned in the first direction by using the limiting assembly 3, and then the battery cell 100 can be positioned in the second direction by using the centering and positioning assembly 2; the battery cell 100 can also be positioned in the second direction by using the centering and positioning assembly 2 and then slightly released, and then the battery cell 100 can be positioned in the first direction by using the limiting assembly 3, and then the battery cell 100 can be positioned in the second direction by using the centering and positioning assembly 2 again.

[0037] In the battery cell laser scribing flow line, the top surface of the insert 4 is provided with a plurality of vacuum adsorption holes 43 for adsorbing and fixing the battery cell 100. Specifically, as Figure 4As shown, the insert 4 includes an insert body 41 and an insert portion 42, and each vacuum adsorption hole 43 is opened on the top surface of the insert portion 42; the insert portion 42 is provided with a first avoidance hole 421 for avoiding the placement platform 1; the top surface of the insert portion 42 is also provided with a second avoidance hole 422 along the first direction, so that the laser scribing mechanism 7 can scribing the battery cell 100 located on the insert portion 42; both ends of the second avoidance hole 422 are through.

[0038] The lateral movement module 5 is connected to the insert body 41, and is used to drive the insert 4 to move back and forth along the first direction. In this embodiment, the lateral movement module 5 is preferably an electric linear slide. The top surface of the insert body 41 is connected to a second limit plate 44 for limiting the battery cell 100, and the second limit plate 44 is arranged opposite to the first limit plate 31 along the first direction.

[0039] When in use, driven by the lateral movement module 5 , the inserting hand 4 moves along the first direction so that the inserting portion 42 is inserted into the groove 13 of the placement platform 1 , so as to adsorb and fix the positioned battery cell 100 on the top surface of the inserting portion 42 .

[0040] In order to ensure the position accuracy of the battery cell 100 on the inserting hand 4, a lifting drive mechanism for driving the inserting hand 4 to move up and down can be added. After the insertion portion 42 of the inserting hand 4 moves and inserts into the groove 13, the lifting drive mechanism drives the inserting hand 4 to move upward, so that the insertion portion 42 fits the bottom surface of the battery cell 100, and the battery cell 100 is fixed by adsorption through each vacuum adsorption hole 43. The lifting drive mechanism can use two lifting cylinders, the fixed end of the lifting cylinder is connected to the moving end of the transverse module 5, and the piston end of the lifting cylinder is connected to the inserting hand 4.

[0041] It should be noted that the placement platform 1 can be designed to be able to place two battery cells 100 side by side along the first direction; accordingly, the insertion portion 42 of the insert 4 can be designed to be able to adsorb and fix two battery cells 100 arranged side by side along the first direction; in this way, it can cooperate with the laser scribing mechanism 7 to realize the processing of two battery cells 100 at a time, thereby improving the working efficiency.

[0042] like Figure 1 and 5 As shown, the laser scribing mechanism 7 is located above the insert 4, and is used to scribing the battery cell 100 adsorbed and fixed on the insert 4. In this embodiment, the laser scribing mechanism 7 includes a laser, a preheater, and an air atomizing nozzle. When the battery cell 100 moves to the scribing position with the insert 4, the laser emits a laser, and the temperature difference between the air atomizing nozzle and the laser is used to finally realize the cracking process through thermal expansion and contraction. The structure of the laser scribing mechanism 7 is prior art, so its structure and working principle are not described in detail.

[0043] In order to prevent the water mist sprayed by the air atomizing nozzle from falling on the equipment and affecting the operation of the equipment, a receiving plate 6 can be arranged below the insert 4.

[0044] In addition, the cell laser scribing line also includes a visual inspection component for visually inspecting the cell 100 after scribing to ensure the scribing quality. The visual inspection component includes an industrial camera and a light source.

[0045] The battery cell laser scribing streamline of the utility model is used by placing the battery cell 100 on the placement platform 1, and accurately positioning the battery cell 100 on the placement platform 1 through the centering positioning component 2 and the limiting component 3; under the drive of the transverse movement module 5, the inserter 4 is inserted into the groove 13 of the placement platform 1, and the battery cell 100 is fixed by the vacuum adsorption holes 43; under the drive of the transverse movement module 5, the inserter 4 and the battery cell 100 fixed by the inserter 4 move together along the first direction, so that the battery cell 100 moves to the slicing position; the laser scribing mechanism 7 slices the battery cell 100; after the slicing is completed, under the drive of the transverse movement module 5, the inserter 4 continues to move along the first direction to move the sliced ​​battery cell 100 to the unloading position.

[0046] The battery cell laser scribing streamline realizes the automatic continuous conveying and laser scribing processing of the battery cell 100, and improves the efficiency of automatic operation. After the battery cell 100 is scribed, it is directly fed to the gripping mechanism in a consignment state, so that the gripping mechanism can take away the scribed battery cell 100. There is no conflict between the structures, and the feeding speed can be significantly improved, which is conducive to improving the scribing efficiency of the battery cell 100.

[0047] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
