The bottom surface of the connecting plate 3 is fixed with a material rack 4, and both sides of the material rack 4 are slidably connected. Two guide rods 5 are fixed to the inner side of the passivation box 1. The outer sides of the two guide plates 6 are provided with guide grooves 7. The inner sides of the two guide grooves 7 are slidably connected with sliders 8. One end of the slider 8 is fixed with a connecting rod 9, and one end of the connecting rod 9 passes through the outer side of the material rack 4 and extends to the inside and is fixed with a guide rail 10. The inner side of the guide rail 10 is slidably connected with a plurality of sliding blocks 11, and a plywood 12 is fixed on one side of the plywood 12, and an anti-slip pad 13 is fixed on one side of the plywood 12.

The guide rail 10 is parallel to the guide rod 5, and the guide rail 10 is perpendicular to the splint 12, and the multiple splints 12 are parallel;

[0023] After the aluminum veneer is placed on the unloading rack 4, the cylinder 2 drives the unloading rack 4 to move downward along the guide rod 5 into the passivation liquid through the connecting plate 3. During this process, the slider 8 on the connecting rod 9 moves downward along the guide groove 7 on the guide plate 6. In the process of sliding from the inclined section of the guide groove 7 to the vertical section, the slider 8 pushes the guide rail 10 toward the middle through the connecting rod 9. The guide rail 10 pushes the clamping plate 12 and the anti-slip pad 13 toward the middle through the sliding block 11, thereby clamping the aluminum veneer. During this process, the clamping plate 12 drives the second connecting block 19 to slide downward along the second movable groove 18 on the second connecting rod 17 through the vertical rod 20. After the clamping plate 12 clamps the aluminum veneer, the second connecting block 19 moves to the end of the second movable groove 18, so that The vertical rod 20 pulls the top splint 12 to move upward, and the sliding block 11 on the splint 12 slides along the guide rail 10.

Through the above process, multiple aluminum veneers can be placed at one time and during the passivation process, multiple aluminum veneers can be arranged at equal intervals, so that the passivation liquid can fully contact the outside of each aluminum veneer, thereby solving the problem of only being able to process one aluminum veneer at a time and low work efficiency.

[0024] The specific usage and function of this embodiment: After the aluminum veneer is placed on the unloading rack 4, the cylinder 2 drives the unloading rack 4 to move downward along the guide rod 5 into the passivation solution through the connecting plate 3. During this process, the slider 8 on the connecting rod 9 moves downward along the guide groove 7 on the guide plate 6. In the process of sliding from the inclined section of the guide groove 7 into the vertical section, the slider 8 pushes the guide rail 10 toward the middle through the connecting rod 9. The guide rail 10 pushes the clamping plate 12 and the anti-slip pad 13 toward the middle through the sliding block 11, thereby clamping the aluminum veneer. During this process, the clamping plate 12 drives the second connecting block 19 along the vertical rod 20. The second movable groove 18 on the second connecting rod 17 slides downward. After the splint 12 clamps the aluminum veneer, the second connecting block 19 moves to the end of the second movable groove 18, so that the vertical rod 20 pulls the top splint 12 to move upward, and the sliding block 11 on the splint 12 slides along the guide rail 10. At the same time, the top splint 12 drives the first connecting rod 14 to move upward. When the first connecting block 16 on the lower aluminum veneer moves to the end of the first movable groove 15, it drives the lower splint 12 to move upward. By calculating downward, multiple aluminum veneers are arranged at equal intervals, so that the passivation liquid can fully contact the outside of each aluminum veneer.
