[0002] With the development of new energy vehicle products, the battery pack housing, as an important protective component of the automotive battery module, needs to take into account the requirements of lightweight, high strength and high sealing. The existing battery pack housings on the market are mainly formed by stamping and welding aluminum alloy plates. During the processing, the inner wall, side wall and weld of the battery pack housing need to be ground to avoid burrs from damaging the battery pack and affecting its safety.

[0015] In summary, the present invention has the following beneficial effects:
[0016] The grinding assembly comprises a horizontally positioned horizontal grinding component and a vertically positioned vertical grinding component, with a weld seam grinding component positioned between them. The horizontal grinding component grinds the bottom surface of the battery pack casing, while the vertical grinding component grinds the side walls. Simultaneously, the weld seam grinding component performs inclined grinding on the weld seams, enabling simultaneous grinding of the bottom plate, side walls, and weld seams in a specific area of the battery pack casing. This significantly increases the efficiency of synchronous grinding. The horizontal grinding component utilizes a horizontal guide sliding groove on a horizontal mounting plate, with a sliding horizontal guide slider within the groove. A first rotating hole is located within the guide slider, and a first grinding rotating shaft is positioned within the hole. A first grinding disc for grinding the bottom surface of the battery pack casing is coaxially fixed to this first grinding disc. A first grinding motor, which drives the rotating shaft, is coaxially fixed to the first grinding rotating shaft. During grinding of the battery pack casing, a rotary conveyor component transports the grinding assembly to a specific area. The first grinding motor drives the first grinding disc to rotate and grind the bottom surface of the battery pack casing. Simultaneously, a horizontal telescopic cylinder drives a horizontal guide slide to reciprocate within a horizontal guide sliding groove, thus grinding the horizontal bottom surface in that area. At the same time, a vertical telescopic cylinder of the vertical grinding assembly drives a vertical guide slide to reciprocate within a vertical guide sliding groove, thus grinding the sidewalls in that area. A reciprocating screw slide drives an inclined guide slider to reciprocate within an inclined guide sliding groove, thus grinding the weld seams in that area. When it is necessary to... When grinding the corner area of the battery pack casing, the rotating conveyor assembly first aligns the sidewall of the inclined mounting plate with the corner line of one side of the battery pack casing. Then, the weld grinding assembly grinds the weld on one side of the corner line. The rotating conveyor assembly then aligns the other side of the inclined mounting plate with the other side of the corner line of the battery pack casing, thus grinding the weld on the other side of the corner line. This process ensures the quality of weld grinding at the corner while avoiding the need for manual grinding, reducing grinding costs and guaranteeing the quality of weld grinding; 2.The cleaning assembly consists of a horizontal and a vertical adsorption seat assembly that completely covers the first and second grinding discs. The horizontal adsorption seat assembly has a central split cylinder and side split cylinders on both sides of the central split cylinder based on opening and closing cylinders. When the horizontal grinding assembly is grinding normally, the central and side split cylinders close to cover the first grinding disc. The slag generated during the grinding process is directly adsorbed and cleaned by the first adsorption hole in the horizontal adsorption seat assembly, preventing the slag from scattering. When it is necessary to grind the side wall at the corner, the opening and closing cylinder near the corner drives the side split cylinder to open, ensuring that the side wall of the first grinding disc can fit against the corner for comprehensive grinding. At this time, most of the slag is also adsorbed and cleaned by the horizontal adsorption seat assembly. A small portion of the slag falls vertically to the weld seam at the bottom due to gravity. The fallen slag is then absorbed and cleaned by the second adsorption hole in the inclined adsorption seat, thus achieving slag cleaning while grinding and ensuring grinding efficiency. .

Laser rangefinders 10 are fixedly connected to both ends of the inclined mounting plate 39 along the horizontal direction. A shape vision sensor 11 for detecting the corner position of the battery pack shell is also fixedly connected to the base 1. The laser rangefinders 10 can accurately measure the distance between the inclined mounting plate 39 and the corner, thereby controlling the rotary conveyor assembly 3 to drive the grinding assembly 4 to move.

A second rotary gear 354 meshing with the first rotary gear 352 is fixedly connected to the rotary shaft of the servo adjustment motor 353. The servo adjustment motor 353 drives the second rotary gear 354 to rotate, which in turn drives the first rotary gear 352 and the rotary mounting plate 36 to rotate. The gear ratio between the first rotary gear 352 and the second rotary gear 354 is not less than 2:1 to ensure the accuracy of the rotary adjustment of the grinding assembly 4.
[0027] refer to Figures 3 to 4Specifically, the horizontal grinding assembly 6 and the vertical grinding assembly 7 have the same structure. The horizontal grinding assembly 6 includes a horizontal guide sliding groove 61 opened along the horizontal direction on the horizontal mounting plate 37 and a horizontal guide slider 62 slidably connected in the horizontal guide sliding groove 61. A horizontal telescopic cylinder 63 is fixedly connected along the horizontal direction on the horizontal mounting plate 37 to drive the horizontal guide slider 62 to slide.

A first grinding disc 66 for grinding the bottom surface of the battery pack housing is fixedly connected to the shaft. A first grinding motor 67 for rotating the first grinding rotating shaft 65 is fixedly connected to the horizontal guide slider 62. The first grinding motor 67 drives the first grinding disc 66 to rotate to grind the bottom surface of the battery pack housing. At the same time, the horizontal telescopic cylinder 63 drives the horizontal guide slide 62 to reciprocate within the horizontal guide sliding groove to complete the grinding of the horizontal bottom surface in this area. The diameter of the first grinding disc 66 is equal to the width of the horizontal mounting plate 37, thus achieving the grinding of the edge of the battery pack housing and avoiding interference.
[0028] refer to Figure 2 Specifically, the vertical grinding assembly 7 includes a vertical guide sliding groove formed along the vertical direction on a vertical mounting plate and a vertical guide slider slidably connected within the vertical guide sliding groove.

A second grinding motor that drives the second grinding rotating shaft to rotate is fixedly connected to the vertical guide slider. The vertical telescopic cylinder drives the vertical guide slide to slide back and forth within the vertical guide sliding groove, thereby completing the grinding of the side wall in this area.
[0029] refer to Figure 2 and Figure 4Specifically, the weld grinding assembly 8 includes an inclined guide sliding groove 81 horizontally formed on an inclined mounting plate 39 and an inclined guide slider 82 slidably connected within the inclined guide sliding groove 81. A reciprocating screw slide 83, horizontally arranged and used to drive the inclined guide slider 82 to slide, is fixedly connected to the inclined mounting plate 39. A third rotating hole 84 is formed in the inclined guide slider 82 in a direction perpendicular to the inclined mounting plate 39. A third grinding rotating shaft 85 is rotatably connected within the third rotating hole 84.

The reciprocating screw slide 83 drives the inclined guide slider 82 to reciprocate within the inclined guide sliding groove 81, thereby completing the grinding of the weld in this area. The use of the reciprocating screw slide ensures that the weld grinding rod 86 has sufficient grinding stroke. In order to ensure that the weld grinding rod 86 can grind the weld at the corner point, the diameter of the weld grinding rod 86 is larger than the diameter of the third grinding rotating shaft 85 so that when the inclined guide slider 82 moves to both ends of the inclined guide sliding groove 81, the weld grinding rod 86 can contact the corner point, thereby realizing the grinding at the right angle corner. A tapered stabilizing platform 88 is fixedly connected to one end of the inclined guide slider 82 near the weld grinding rod 86. The stabilizing platform 88 has a stabilizing rotation hole 89 for the third grinding rotating shaft 85 to rotate.

A second adsorption chamber 99 is provided in the inclined adsorption seat 97 to connect the second adsorption holes 98. A second adsorption tube 910 is connected to the outside of the second adsorption chamber 99. By setting the inclined adsorption seats 97 at the upper and lower ends of the third grinding rotating shaft 85, the welding slag that is ground off can be adsorbed synchronously during the welding process, so as to avoid the welding slag from flying at the weld and to further adsorb the fallen welding slag.

When the horizontal grinding assembly 6 is grinding normally, the central split cylinder 922 and the side split cylinders 923 close to cover the first grinding disc 66. The first grinding disc 66 grinds... The slag powder generated during the process is directly adsorbed and cleaned by the first adsorption hole 93 in the horizontal adsorption seat assembly 92, preventing the slag powder from scattering. When it is necessary to grind the side wall at the corner, the opening and closing cylinder 924 near the corner drives the side split cylinder 923 to open, so as to ensure that the side wall of the first grinding disc 66 can fit with the corner to achieve full grinding. At this time, most of the slag powder is also adsorbed and cleaned by the horizontal adsorption seat assembly 92. A small part of the slag powder falls vertically to the bottom weld due to gravity. The fallen slag powder is absorbed and cleaned by the second adsorption hole 98 in the inclined adsorption seat 97, thus achieving cleaning of slag powder while grinding, ensuring grinding efficiency.
[0032] Brief description of the usage process: When grinding the battery pack casing, the rotary conveyor assembly 3 transports the grinding assembly 4 to a certain area. The first grinding motor 67 drives the first grinding disc 66 to rotate and grind the bottom surface of the battery pack casing. Simultaneously, the horizontal telescopic cylinder 63 drives the horizontal guide slide 62 to reciprocate within the horizontal guide sliding groove, thus completing the grinding of the horizontal bottom surface in that area. At the same time, the vertical telescopic cylinder 73 of the vertical grinding assembly 7 drives the vertical guide slide 72 to reciprocate within the vertical guide sliding groove 71, thus completing the grinding of the sidewalls in that area. The screw slide 83 drives the inclined guide slider 82 to reciprocate within the inclined guide sliding groove 81, thereby completing the grinding of the weld seam in that area. When it is necessary to grind the corner area of the battery pack housing, the conveying assembly 3 is first rotated so that the side wall of the inclined mounting plate 39 is in contact with the corner line on one side of the battery pack housing. Then the weld grinding assembly 8 grinds the weld seam on one side of the corner line. Then the conveying assembly 3 is rotated again so that the other side of the inclined mounting plate 39 is in contact with the other side of the corner line of the battery pack housing, thereby grinding the weld seam on the other side of the corner line.
