Description

Technical Field

[0001] The invention relates to the technical field of battery production, and in particular to a surface treatment system for negative plate grids of power-assisted vehicle batteries. Background Art

[0002] In the manufacturing process of lead-acid batteries, the plate is the skeleton of the positive and negative plates of the battery, which is equivalent to human bones. Lead paste is applied to the grid to make the plate. At present, the advanced continuous casting process has been introduced into the grid production process of the battery industry. However, a small amount of mold release oil will remain on the surface of the grid produced by the continuous casting process, making the surface finish of the battery grid too high, which is not conducive to the combination of the lead paste and the grid. During the discharge process of the battery, the lead paste will fall off, affecting the service life of the battery. Therefore, the battery grid needs to be sandblasted and the grid surface needs to be optimized to remove the oil on the grid surface and increase the surface area and surface roughness.

[0003] The existing sandblasting operation environment is harsh. During the sandblasting of the battery grid, a large amount of dust will be generated, and the workers need to wear protective clothing. The dust contains a large amount of abrasives, which will be wasted if not recovered in time. The existing sandblasting methods are mostly operated by handheld sandblasting guns. When sandblasting, one side of the grid needs to be sandblasted first, and then the other side of the grid is sandblasted. The sandblasting efficiency is low and is not conducive to continuous sandblasting.

[0004] The patent document with publication number CN118386144A discloses a battery grid sandblasting device.

[0037] The sandblasting device comprises a second rotating shaft 14 , which is rotatably connected to the top plate of the box body 1 , passes through the top plate of the box body 1 , and is connected to a driving assembly on the box body 1 .

[0038] The driving assembly includes a second motor 11 fixed on the housing 1 , a second gear 12 is coaxially fixed on the output shaft of the second motor 11 , a third gear 13 is coaxially fixed on the upper end of the second rotating shaft 14 , and the second gear 12 is meshed with the third gear 13 .

[0039] A mounting frame 15 is fixed to the lower end of the second rotating shaft 14, and a third rotating shaft 16 is rotatably connected to one side of the mounting frame 15. A fourth gear 17 is fixed to the third rotating shaft 16. A gear ring 18 concentric with the second rotating shaft 14 is fixed to the top plate of the box body 1, and the fourth gear 17 is meshed with the gear ring 18. A connecting ring 19 is eccentrically fixed to the lower end of the third rotating shaft 16, and one end of the connecting ring 19 away from the third rotating shaft 16 is tilted downward, and one end of the connecting ring 19 away from the third rotating shaft 16 is rotatably connected to a swing rod 21, a ball head 20 is fixedly sleeved on the swing rod 21, the ball head 20 is rotatably connected to the mounting frame 15, and the swing rod 21 is tilted.

[0040] A mounting plate 22 is fixed at the lower end of the swing rod 21, and the swing rod 21 is perpendicular to the mounting plate 22. A plurality of nozzles 23 are fixed at the lower end of the mounting plate 22, and the nozzles 23 are perpendicular to the mounting plate 22. The plurality of nozzles 23 are connected to the sand supply assembly and the air supply assembly.

[0041] The sand supply assembly includes a guide hopper 34 fixed in the box 1 below the clamping drive device, the lower end of the guide hopper 34 is fixedly connected to a sand box 30, the sand box 30 is connected to the inlet end of the sand supply pump 33, and the outlet end of the sand supply pump 33 is connected to a hose. The sand supply pipe 29 passes through the second rotating shaft 14 and the third gear 13, the upper end of the sand supply pipe 29 is connected to the hose through a rotating joint, and the lower end of the sand supply pipe 29 is connected to the connecting pipe 28, and the connecting pipe 28 is connected to the nozzle 23 through the sand inlet pipe 27.

[0042] The air supply assembly includes a high-pressure air pump 26 fixed to the lower end of the mounting plate 22 . The outlet end of the high-pressure air pump 26 is connected to the air pipe 25 , and the air pipe 25 is connected to the nozzle 23 through the branch pipe 24 .

[0043] When in use, the conveyor conveys the negative grid of the battery to be processed to the feed port of the box 1, and the door panel 2 at the feed port slides upward and opens the feed port. After the negative grid of the battery enters the box 1 through the feed port, the clamps 8 on both sides clamp the two ends of the negative grid of the battery. Then, the first motor 3 starts to drive the lead screw 5 to rotate, so that the lead screw 5 drives the clamp 8 to move toward the middle of the box 1 through the slider 6, and the door panel 2 at the feed port moves downward to close the feed port to prevent sand and gravel from flying out during sandblasting. When the slider 6 and the clamp 8 drive the negative grid of the battery to move, the first gear 9 and the shield 10 move accordingly. Since there is rotation damping between the first rotating shaft 7 and the slider 6, the negative grid of the battery cannot rotate when the slider 6 and the clamp 8 drive the negative grid of the battery to move and when the negative grid of the battery is sandblasted.

[0044] When the slider 6 and the clamp 8 drive the negative grid of the battery to move below the multiple nozzles 23, the first motor 3 is turned off and the second motor 1 is started. The second motor 11 drives the second gear 12 to rotate. Under the meshing action of the second gear 12 and the third gear 13, the second shaft 14 drives the mounting frame 15 to rotate in the box 1, and the fourth gear 17 rotates around the gear ring 18. Under the meshing action of the gear ring 18 and the fourth gear 17, the fourth gear 17 drives the third shaft 16 to rotate, and the connecting ring 19 drives the swing rod 21 to swing with the ball head 20 as the rotation point, and finally the mounting plate 22 drives the multiple nozzles 23 to rotate while continuously swinging.

[0045] Since the multiple nozzles 23 rotate and swing continuously, the nozzles 23 can sandblast the surface of the battery negative grid from multiple angles. Therefore, the sides of the transverse ribs and longitudinal ribs of the battery negative grid can be effectively sandblasted during sandblasting, which can increase the sandblasting area of ​​the battery negative grid and improve the adhesion of the lead paste on the battery negative grid.

[0046] During the sandblasting process, the sand supply pump 33 delivers the sand in the sand box 30 to the nozzle 23 through the sand supply pipe 29, the connecting pipe 28 and the sand inlet pipe 27. At the same time, the high-pressure air pump 26 supplies high-pressure gas to the nozzle 23 through the air pipe 25 and the branch pipe 24. The high-pressure gas drives the sand to spray toward the negative grid of the battery through the nozzle 23 to complete the sandblasting.

[0047] The ejected sand particles flow back into the sand box 30 through the guide hopper 34 for recycling.

[0048] At the same time, since the protective cover 10 is arranged outside the first gear 9 , the ejected sand particles will not affect the first gear 9 .

[0049] After the sandblasting of the negative grid of the battery is completed, the first motor 3 is started again and the slider 6 is moved toward the discharge port. After the first gear 9 is meshed with the rack 31, the first gear 9, the first rotating shaft 7, the clamp 8 and the negative grid of the battery are rotated during the slider 6 continues to move toward the discharge port. After the negative grid of the battery is flipped 180 degrees, the electric telescopic rod 32 drives the rack 31 to move and causes the rack 31 to be misaligned with the first gear 9. The first motor 3 causes the slider 6 to move toward the feed port through the lead screw 5, and the flipped negative grid of the battery is brought to the bottom of the multiple nozzles 23 for sandblasting. After the sandblasting of both sides of the negative grid of the battery is completed, the first motor 3 is started again to move the sandblasted negative grid of the battery to the discharge port, and the door panel 2 at the discharge port is opened to take the negative grid of the battery out of the discharge port.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
