[0029] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0030] Example 1
[0031] like Figure 1 and Figure 2 As shown, a vision inspection milling mechanism includes a slide plate 100, a lifting assembly 200 mounted on the slide plate 100, a carriage 300 mounted on the drive end of the lifting assembly 200, and a milling assembly 400 and a detection assembly 500 mounted on the carriage 300. The milling assembly 400 and the detection assembly 500 are spaced apart along the X direction. The carriage 300 is slidably connected to the slide plate 100 to ensure the stability of the carriage 300 during Z-direction movement.
[0032] Specifically, the slide plate 100 is slidably mounted on the truss 700, and the truss 700 drives the slide plate 100 to perform XY direction movements. The truss 700 is existing technology. The lifting assembly 200 adopts a linear module. The entire mechanism is controlled by a control cabinet.
[0033] By installing the milling assembly 400 and the inspection assembly 500 on the carriage 300, the mechanism can simultaneously perform both weld inspection and weld milling functions. The structure is compact, the integration is improved, and the floor space is reduced.
[0034] like Figure 1 and Figure 3As shown, the milling assembly 400 includes a slider 410, a connecting block 420, a milling machine 430, a mounting block 440, a dust cover 450, a floating assembly 460, and a first driving member. The slider 410 is slidably mounted on the carriage 300. The milling machine 430 is connected to the slider 410 via the connecting block 420. The mounting block 440 is mounted on the slider 410 and positioned below the connecting block 420. The dust cover 450 is positioned directly below the milling machine 430, and the milling cutter on the milling machine 430 extends into the dust cover 450. The dust cover 450 is connected to the mounting block 440 via the floating assembly 460. The dust cover 450 is connected to a cleaning device (not shown in the figure) via a dustproof pipe. The floating assembly 460 is slidably connected to the slider 410. The first driving member is mounted on the carriage 300 and is used to drive the slider 410 to move along the Z direction.
[0035] Specifically, the milling machine 430 is existing technology; the bottom of the dust cover 450 is open, and the side of the dust cover 450 is provided with an air blowing hole 451. The air blowing hole 451 is connected to the air blowing equipment through an air pipe, so that the welding slag and debris inside the dust cover 450 generate an air vortex, so that the dust pipe can suck up the dust; the first driving component is a cylinder; the cleaning equipment can be a vacuum cleaner.
[0036] By setting the floating group 460, the dust cover 450 is kept in close contact with the battery cell during the milling process, so that the welding slag and debris generated during the milling process of the milling machine 430 are sealed inside the dust cover 450. The welding slag and debris are effectively controlled and prevented from flying outwards. This achieves the dust prevention effect and avoids short circuits in the battery cell.
[0037] like Figure 3 and Figure 4 As shown, the floating assembly 460 includes a floating block 461, a corner plate 462, a sliding shaft 463, and an elastic element 464. The floating block 461 is positioned below the mounting block 440. The floating block 461 is connected to the dust cover 450 via the corner plate 462, which is slidably connected to the slider 410. One end of the sliding shaft 463 is connected to the floating block 461, and the other end of the sliding shaft 463 slides through the mounting block 440. The elastic element 464 is sleeved on the sliding shaft 463, with one end abutting against the floating block 461 and the other end abutting against the mounting block 440. Specifically, the elastic element 464 is a spring.
[0038] During the downward movement of the first driving component driving the slider 410, the dust cover 450 first contacts the battery cell. As the slider 410 continues to move downward, it forces the dust cover 450 to move upward, and the elastic element 464 is compressed until the milling cutter on the milling machine 430 descends into place.
[0039] like Figure 3 and Figure 4As shown, the milling assembly 400 also includes a displacement limiting group 470, which includes a displacement sensor 471, a displacement contact block 472, and a displacement limiting block 473. The displacement sensor 471 is mounted on the mounting block 440, and the displacement contact block 472 is mounted on the floating block 461. The displacement sensor 471 and the displacement contact block 472 are correspondingly arranged. The displacement limiting block 473 is mounted on the mounting block 440 and is disposed between the mounting block 440 and the floating block 461.
[0040] By setting the displacement limit group 470, the downward displacement of the milling machine 430 is limited to prevent the milling machine 430 from descending too much and causing over-milling of the weld, thus ensuring the milling quality.
[0041] When the milling cutter on the milling machine 430 descends to the target position, the dust cover 450 moves upward due to the reaction force of the battery cell. The displacement contact block 472 moves upward and contacts the displacement sensor 471. The displacement sensor 471 sends a signal, and the milling machine 430 stops descending. If the displacement sensor 471 is damaged and fails to send a signal in time, the displacement limit block 473 acts as a hard limit to prevent the milling cutter from continuing to descend and causing over-milling of the weld.
[0042] like Figure 1 and Figure 3 As shown, the milling assembly 400 also includes a dust collection box 480 and an anemometer; the dust collection box 480 is installed on the dustproof duct and is located next to the dust cover 450 to prevent welding slag from flowing back onto the battery cell when the cleaning equipment is switched or stopped, thereby further avoiding battery cell short circuits; the anemometer is installed on the carriage 300.
[0043] like Figure 1 , Figures 3-5 As shown, the milling assembly 400 also includes a buffer limiting group 490, which includes a buffer 491, a limiting bolt 492, and a buffer block 493. The buffer 491 and the limiting bolt 492 are installed at the bottom of the carriage 300, and the buffer block 493 is installed on the slider 410. Specifically, there are two milling assemblies 400, which are respectively arranged on both sides of the slider 410.
[0044] The buffer 491, limit bolt 492 and buffer block 493 are designed to provide flexible buffering and hard limit when the slider 410 moves down to the end of its stroke, so as to avoid rigid collision and excessive downward movement.
[0045] To monitor whether the milling cutter on the milling machine 430 has broken at all times, a reflection sensor is installed on the angle plate 462.
[0046] like Figure 1 and Figure 5As shown, the detection component 500 includes a fixed group 510 and an adjusting group 520; the fixed group 510 and the adjusting group 520 are arranged along the X direction. By cooperating with the fixed group 510 and the adjusting group 520, the distance between the adjusting group 520 and the fixed group 510 is adjustable to accommodate the spacing between the terminals of different product cells, thereby improving the practicality and versatility of the mechanism.
[0047] like Figure 5 As shown, the fixed assembly 510 includes a first 3D profiler 511, a first camera 512 and a first vertical plate 513. The first 3D profiler 511 is mounted below the slide 300 via the first vertical plate 513, and the first camera 512 is mounted on the side of the slide 300 away from the slide plate 100.
[0048] like Figure 5 and Figure 6 As shown, the adjustment group 520 includes a second 3D profilometer 521, a second camera 522, a second vertical plate 523, and a second drive member 524. The second vertical plate 523 is slidably mounted on the slide 300. The second 3D profilometer 521 is mounted below the slide 300 via the second vertical plate 523. The second camera 522 is connected to the second vertical plate 523. The second drive member 524 is mounted on the slide 300 and is used to drive the second vertical plate 523 to move along the X direction.
[0049] Specifically, the slide 300 has a through hole for the second vertical plate 523 to pass through; the second driving component 524 includes a motor, a lead screw, and a lead screw nut. The lead screw is installed on the slide 300 and positioned between the slide plate 100 and the slide 300. The motor drives the lead screw to rotate, and the lead screw nut is sleeved on the lead screw. The lead screw nut is connected to the second vertical plate 523. This is prior art and will not be described further here; the adjustment group 520 is set in three groups. In one group, the second camera 522 is set on the same side as the first camera 512. In the other two groups, the second camera 522 is set on the side of the slide plate 100 away from the slide 300; a light source is installed at the bottom of the slide 300, and the light source is positioned below the first camera 512 and the second camera 522.
[0050] The first camera 512 and the second camera 522 are used to acquire surface images of the weld, and the first 3D profilometer 511 and the second 3D profilometer 521 are used to acquire contour images of the weld, thereby ensuring detection accuracy.
[0051] like Figure 1 and Figure 5As shown, the vision inspection milling mechanism also includes a limiting component 600; the limiting component 600 includes a limiting plate 610 and a limiting pin 620. The limiting plate 610 is mounted on the top of the slide plate 100, and the limiting pin 620 is mounted on the top of the carriage 300. The limiting plate 610 has a limiting hole for the insertion of the limiting pin 620. The limiting component 600 is provided to provide limiting protection when the vision inspection milling mechanism is being maintained.
[0052] During operation, the truss 700 drives the slide plate 100 to move in the XY direction until the detection component 500 reaches the cleaned battery cell. The detection component 500 detects whether the weld is too high. If it is too high, it controls the milling component 400 to perform a shearing operation.
[0053] Example 2
[0054] This embodiment further defines the truss 700 in Embodiment 1, such as... Figure 2 , Figures 5-7 As shown, the truss 700 includes a base frame 710, a crossbeam 720, a first drive assembly 730, and a second drive assembly 740. The two ends of the crossbeam 720 are respectively attached to the base frame 710 and slide in cooperation with the base frame 710. The first drive assembly 730 is mounted on the base frame 710 and is used to drive the crossbeam 720 to move in the Y direction. The second drive assembly 740 is mounted on the crossbeam 720 and is used to drive the slide plate 100 to move in the X direction.
[0055] Specifically, there are two crossbeams 720, which are arranged side by side along the Y direction to form a dual workstation, further improving the processing efficiency; the two ends of the crossbeams 720 are respectively connected to the base frame 710 by means of a mounting plate, and the mounting plate is slidably connected to the base frame 710.
[0056] Both the first drive assembly 730 and the second drive assembly 740 include a motor, a gear, and a rack. The gear is installed at the output end of the motor and meshes with the rack. In the first drive assembly 730, the motor is installed on the mounting plate, and the rack is installed on the base frame 710 and extends along the Y direction. In the second drive assembly 740, the motor is installed on the slide plate 100, and the rack is installed on one side of the crossbeam 720 and extends along the X direction.
