Description

Technical Field

[0001] The invention relates to the technical field of battery production, and in particular to a lead paste coating device for a battery substrate. Background Art

[0002] The substrate of a lead-acid battery is an important component. The substrate is used as a carrier of lead paste. When producing lead-acid batteries, it is necessary to apply lead paste on the substrate so that the lead paste adheres to the surface of the substrate with a uniform thickness. This processing procedure is usually completed by a coating machine, but the existing coating machine still has the following shortcomings:

[0003] 1. The existing coating machine uses a material storage box to store and discharge lead paste, and uses a conveying mechanism to continuously convey the substrate. The lead paste falling on the substrate enters between the upper and lower pressure rollers under the drive of the substrate to achieve the coating of the lead paste on the surface of the substrate. However, in the actual production process, the lead paste falling on the substrate is prone to slipping on the surface of the substrate after contacting the upper and lower pressure rollers, resulting in insufficient lead paste coating on the surface of the substrate, and the discharge port of the material storage box is prone to blockage, which is prone to insufficient lead paste discharge, thereby affecting the coating quality of the substrate;

[0004] 2. In the actual processing process, the upper pressure roller is easy to adhere and roll up the lead paste applied on the substrate, resulting in partial loss of lead paste on the substrate. Although the lead paste on the pressure roller can be removed by a scraper, the missing part of the lead paste on the substrate needs to be filled and repaired manually, which is a more troublesome operation.

The upper edge of the left side of the scraper frame 101 just contacts the surface of the upper pressure roller 5 to scrape off the lead paste adhered to the surface of the upper pressure roller 5. The right opening of the scraper frame 101 is used to pop out the lead paste.

[0032] The working process of the present invention is as follows:

[0033] When it is necessary to apply lead paste to the surface of the lead-acid battery substrate, the substrate is placed on the first conveying mechanism 2, and one end of the substrate is passed through the gap between the upper pressing roller 5 and the lower pressing roller 6. The first conveying mechanism 2 conveys the substrate, and the lead paste in the storage box 7 is discharged to the surface of the substrate. The upper pressing roller 5 and the lower pressing roller 6 are driven to rotate by the first motor 12 and the second motor 13 respectively, so that the lead paste enters between the upper pressing roller 5 and the lower pressing roller 6 and is applied to the surface of the substrate. The substrate coated with lead paste is conveyed out by the second conveying mechanism 3.

[0034] During the process of applying the lead paste, the pushing motor 88 drives the driving disk 86 to rotate, so that the driving column 87 on the driving disk 86 slides in the straight groove ring 85, and the straight groove ring 85 drives the rack 84 to produce a linear reciprocating sliding, so that the gear 83 produces a reciprocating rotation, and the gear 83 drives the pushing plate 81 to rotate reciprocatingly through the first rotating shaft 82, so that the pushing plate 81 pushes the lead paste that falls on the substrate toward the upper pressure roller 5 and the lower pressure roller 6, so as to avoid the lead paste from sliding on the substrate and make the thickness of the lead paste applied uniform.

[0035] During the reciprocating rotation of the push plate 81, the push plate 81 drives the dredging frame 91 to slide reciprocatingly up and down through the connecting rod 93. The dredging frame 91 drives the dredging column 92 installed thereon to enter the opening at the lower end of the storage box 7 to dredge it. The dredging plate on the dredging column 92 can hook out the blocked lead paste, thereby improving the dredging effect.

[0036] When lead paste adheres to the upper pressure roller 5, the lead paste on the upper pressure roller 5 will be scraped off by its upper left edge when it rotates to the position of the scraper frame 101 and fall into the scraper frame 101. The pushing motor 88 drives the second rotating shaft 104 to rotate through the transmission belt 106. The second rotating shaft 104 drives the driving blocks 105 on both sides to rotate, so that the driving blocks 105 squeeze the two sides of the elastic plate 102. At this time, the spring 103 is compressed and stores energy. When the plane on the driving block 105 contacts the two sides of the elastic plate 102, the spring 103 releases energy, so that the elastic plate 102 slides quickly to eject the lead paste. The ejected lead paste falls to the right side of the substrate missing the lead paste. When the substrate missing the lead paste passes through the re-pressing roller 11, the ejected lead paste can be pressed to the concave area of ​​the substrate missing the lead paste, thereby repairing the missing lead paste on the substrate.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
