Detailed Description
Fig. 1 is a schematic structural view of the present invention; FIG. 2 is a cross-sectional view of the present invention; FIG. 3 is a schematic view of the present invention mounted on a guide rail; referring to fig. 1 to 3, a dispensing table 1 of a die bonder suitable for DFN products is fixed on a guide rail 9 of the die bonder, two protruding surfaces 2 are arranged on the dispensing table 1, a plurality of through holes 3 are arranged in the middle of the protruding surfaces 2, a connecting air faucet 4 is arranged at one end of the dispensing table 1, and the connecting air faucet 4 is connected with the through holes 3 through a channel 5.
The two ends of the dispensing table 1 are provided with positioning blocks 6, and the positioning blocks 6 are matched with a positioning rod 10 in the middle of the guide rail 9 and are conveniently arranged on the guide rail 9; the connecting air tap 4 is connected with the vacuum converter 8 through the air pipe 7, the number of the through holes 3 of the convex surface 2 is 20-40, the diameter of the through holes 3 is 0.2-0.7 mm, the height of the convex surface 2 is 0.3-0.8 mm, the number of the through holes 3 is 22, the diameter of the through holes 3 is 0.3mm, and the height of the convex surface 2 is 0. Smm.
The DFN product is conveyed to the guide rail 9 from a material placing rack of the die bonder and then conveyed to the dispensing table 1 through the guide rail 9, at the moment, the through holes 3 are vacuumized, the DFN product is sucked by the 22 through holes 3, so that the DFN product can be tightly attached to the dispensing table 1, then the DFN product is dispensed, and the DFN product is conveyed to the next procedure through the guide rail 9 after the dispensing is finished.
In a word, the utility model discloses can make the DFN product hug closely on the platform of strickleing off the glue, avoid the point to glue unstable phenomenon, improve productivity ratio.
