When the lead frame 2 needs to be cleaned, a user starts the first pumping part 103 and the material conveying belt 107 through the control terminal, pumps the cleaning liquid in the water storage tank 102 through the first pumping part 103, enables the cleaning liquid to enter the water inlet on the right side of the water storage tank 102, and flows into the water storage tank 102 again from the water outlet on the right side of the water storage tank 102 through the connecting pipe, so that circulation is formed, and water in the water storage tank 102 is enabled to be water.
After the cleaning solution in the water storage tank 102 starts to move, the material conveying belt 107 drives the seven L-shaped connecting frames 108 and the sliding frames 109 and the upper parts thereof to move clockwise along the sliding grooves of the fixing frame 1071, and when one of the L-shaped connecting frames 108 and the sliding frames 109 and the upper parts thereof moves to the right part of the material conveying belt 107 and higher than the middle part thereof, taking fig. 7 and 8 as an example, the two sliding frames 109 and the fixing pins 1091 gradually move towards each other along the sliding grooves of the fixing frame 1071, so that the two sliding frames 109 and the four U-shaped frames 110 move towards each other, and the lead frame 2 is clamped and fixed by the opposite movement of the four U-shaped frames 110.
After the U-shaped frame 110 clamps and fixes the lead frame 2, the material conveying belt 107 drives the L-shaped connecting frame 108, the sliding frame 109 and the lead frame 2 clamped by the U-shaped frame 110 to move continuously, the L-shaped connecting frame 108 and the upper parts thereof move from the right part of the fixing piece 106 to the middle part of the fixing piece 106, after the L-shaped connecting frame 108 and the upper parts thereof move to the middle part of the fixing piece 106, the lead frame 2 clamped by the L-shaped connecting frame 108 and the U-shaped frame 110 is positioned in the cleaning liquid of the water storage tank 102, the lead frame 2 is immersed in the cleaning liquid of the water storage tank 102, the cleaning liquid in the water storage tank 102 cleans foreign matters on the lead frame 2, and the cleaning liquid in the water storage tank 102 washes the foreign matters remained on the lead frame 2 in the flowing process, so that the foreign matters remained on the lead frame 2 are further reduced.
In the process that the L-shaped connecting frame 108, the lead frame 2 and the upper parts of the lead frame are moved along with the material conveying belt 107, the material conveying belt 107 rotates clockwise, and under the action that the flowing direction of the cleaning liquid in the water storage tank 102 is from left to right, the cleaning liquid in the water storage tank 102 is enabled to wash the foreign matters washed out of the lead frame 2 to the right side of the lead frame 2, so that the phenomenon that the washed foreign matters are sticky to the lead frame 2 again and the lead frame 2 is not qualified is avoided.
