The bearing plates of the first side ink pad 3, the second side ink pad 4 and the middle ink pad 2 are folded to form a closed printing table top, and the adsorption holes on the printing table top adsorb the battery pieces borne on the printing table top, so that the battery pieces are prevented from sliding in the printing process.

Optionally, as shown in fig. 7 to 8, the bearing plates of the first side ink pad 3, the second side ink pad 4 and the middle ink pad 2 are made of transparent or semitransparent materials, and light sources are disposed in the vacuum cavities of the first side ink pad 3, the second side ink pad 4 and the middle ink pad 2. In the printing process, the light that the light source sent shines to the battery piece through the loading board to the realization is polished to the battery piece, improves the location effect to the battery piece, finally promotes the printing effect.

The second slide rail 7 is arranged on the frame 1 and located on a second side of the middle ink pad 2, the second side ink pad 4 is slidably connected to the second slide rail 7, and the second side ink pad 4 slides along the second slide rail 7 between a second separated position and a second folded position.

Alternatively, as shown in figure 6, the first slide track 6 is inclined downwardly away from the intermediate pad 2, and when the first side pad 3 is slid to the first spaced apart position, the carrier plate 32 of the first side pad 3 is lower than the carrier plate 22 of the intermediate pad 2. Similarly, the second slide track 7 is inclined downwardly away from the intermediate pad 2 and the carrier plate 42 of the second side pad 4 is lower than the carrier plate 22 of the intermediate pad 2 when the second side pad 4 is slid to the second spaced apart position. Optionally, the range of the inclination angles between the first slide rail 6 and the second slide rail 7 and the horizontal plane is (0,10], the unit of the inclination angle is (0, 10), that is, the two inclination angles are the same value or different values respectively in the range of (0, 10), for example, the inclination angles between the first slide rail 6 and the horizontal plane and the second slide rail 7 are both 2 °, or the inclination angles are more flexibly set according to specific needs, for example, one inclination angle is 1 °, the other inclination angle is 2 °, and the like, which are not listed.
