Description

Technical Field

[0001] The invention belongs to the technical field of printing equipment, and in particular relates to a battery steel sheet ink printer. Background Art

[0002] Battery steel sheets are a material used to manufacture battery shells or internal structural components. Battery steel sheet ink printer is a device specially used to print logos, text, patterns or anti-counterfeiting marks on battery shells. Usually, the battery steel sheet is punched into the shape of the battery shell, and then printed using an ink printer. When printing battery steel sheets, the following problems exist:

[0003] 1. When printing on the surface of battery steel sheets, the logo on the battery steel sheets is small and has high requirements for clarity, so pad printing is usually used for ink printing. However, dust, impurities and oil stains are easily attached to the surface of the steel sheets. Using a simple non-woven cloth to wipe it cannot effectively remove the impurities on the surface, resulting in the problem of weak ink bonding and easy falling off;

[0004] 2. When using a pad printer to print battery steel sheets, a single pad printing head is usually used to print one by one, which has low work efficiency.

[0005] 3. Before pad printing, the battery steel sheet needs to be positioned and clamped to ensure accurate positioning of the battery steel sheet. Usually, the battery steel sheet is clamped into the positioning groove for positioning. This positioning method is inconvenient to take, which reduces the printing efficiency, and the stability of the positioning clamping is poor. There is no precise positioning and limit between the battery steel sheet and the pad printing head. The pad printing head is prone to deflection during pad printing, which reduces the accuracy of printing. Summary of the invention

[0047] When the battery steel sheets are separated and clamped stably, the electromagnetic valve at the bottom of the ink cartridge 16 is opened, and the ink on the ink cartridge 16 flows from the electromagnetic valve to the pattern on the pad printing plate 12. When the ink outflow time reaches the set value, the electromagnetic valve is closed. At this time, the electric slide rail 3 drives the electric slider 11 to move backward, and synchronously drives the L-shaped frame 13 and the No. 1 hydraulic cylinder 23 thereon to move backward, and synchronously drives the No. 1 mounting plate 24 and the silicone pad printing head 25 thereon to move backward, and at the same time drives the No. 1 connecting plate 14 and the sliding plate 15 thereon to move backward, and then starts the No. 1 hydraulic cylinder 23, and the output end of the No. 1 hydraulic cylinder 23 begins to extend, synchronously driving the No. 1 mounting plate 24 and the silicone pad printing head 25 thereon to move backward.
