Description
Technical field
The utility model is specifically related to a kind of nozzle unit of loader, belongs to the process equipment technical field manufacturing semiconductor microelectronics device.
Background technology
Nozzle unit described in the utility model be matched by the vacuum soldering tip of trip bolt and loader to fill, and described nozzle unit is communicated with vacuum source by soldering tip, and loader is used to chip and chi frame equipped mutually.
When load, nozzle unit utilizes negative pressure of vacuum picked up by chip and be contained on chi frame by chip; But existing nozzle unit head has rounded chip adsorption zone (as shown in Figure 3), the contact area of it and chip is larger, like this in load process, therefore nozzle unit can cause chip surface and weigh wounded, make chip surface impaired, reduce the qualification rate of load, and its adsorption capacity is less; Easily cause absorption chip failure, and affect load work efficiency.
Summary of the invention
The purpose of this utility model is: provide one can improve load qualification rate, reduce the nozzle unit of loader chip surface being caused to damage in load process, to overcome the deficiencies in the prior art.
In order to achieve the above object, the technical solution of the utility model: a kind of nozzle unit of loader, comprise suction nozzle rod and suction nozzle, described suction nozzle rod lower end and suction nozzle load, the axis of suction nozzle rod has the first vacuum runner, and the axis of suction nozzle has the second vacuum runner, and the first vacuum runner communicates with the second vacuum runner, and the head of suction nozzle has vacuum sucking holes, and vacuum sucking holes is connected with the second vacuum runner; Its innovative point is: the head of described suction nozzle has the adsorption zone for absorbent core sheet, and the shape of adsorption zone is square and its surrounding is greater than the surrounding of chip, and described vacuum sucking holes is positioned at the centre of the adsorption zone of described chip.
In technique scheme, described suction nozzle rod is cylindrical metal suction nozzle rod, and described suction nozzle is by the high temperature resistant bakelite suction nozzle formed in circular cone shape nozzle head and in cylindric suction nozzle body of rod one.
In technique scheme, the body of rod of described suction nozzle rod seals load by boss through hole matching pair and suction nozzle body of rod tight fit.
The good effect that the utility model has is: after adopting the nozzle unit of above-mentioned loader, owing to reducing the contact area of nozzle head and chip, the head reducing suction nozzle, because of the damage for chip effective coverage after wearing and tearing, overcomes the defect that chip surface is impaired; And enhance adsorption capacity, effectively improve absorption chip and implement the work efficiency of load and improve load qualification rate.Achieve the purpose of this utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the structural representation of prior art chips adsorption zone.
Embodiment
Below in conjunction with accompanying drawing and the embodiment that provides, the utility model is further described, but is not limited thereto.
As shown in Figure 1, 2, a kind of nozzle unit of loader, comprise suction nozzle rod 1 and suction nozzle 2, described suction nozzle rod 1 lower end and suction nozzle 2 load, the axis of suction nozzle rod 1 has the first vacuum runner 1-1, and the axis of suction nozzle 2 has the second vacuum runner 2-1, and the first vacuum runner 1-1 communicates with the second vacuum runner 2-1, and the head of suction nozzle 2 has vacuum sucking holes 2-2, and vacuum sucking holes 2-2 is connected with the second vacuum runner 2-1; And its: the head of described suction nozzle 2 has the adsorption zone 2-3 for absorbent core sheet, and the shape of adsorption zone 2-3 is square and its surrounding is greater than the surrounding (being namely greater than the effective coverage that chip inner ring has electrical property) of chip, described vacuum sucking holes 2-2 is positioned at the centre of the adsorption zone 2-3 of described chip.
As shown in Figure 1, in order to make the utility model structure simple, compact, described suction nozzle rod 1 is cylindrical metal suction nozzle rod, and described suction nozzle 2 is by the high temperature resistant bakelite suction nozzle formed in circular cone shape nozzle head 2-4 and in cylindric suction nozzle body of rod 2-5 one.
As shown in Figure 1, be equipped with mutually for the ease of suction nozzle rod 1 and suction nozzle rod 2, the body of rod 1-2 of described suction nozzle rod 1 seals load by boss through hole matching pair 3 and suction nozzle body of rod 2-5 tight fit.
Head due to suction nozzle 2 described in the utility model has the adsorption zone 2-3 for absorbent core sheet, and the shape of adsorption zone 2-3 is square and its surrounding is greater than chip surrounding (being namely greater than the effective coverage that chip inner ring has electrical property), therefore, reduce the contact area of nozzle head and chip, the head reducing suction nozzle, because of the damage for chip effective coverage after wearing and tearing, overcomes the defect that chip surface is impaired; And enhance adsorption capacity, effectively improve absorption chip and implement the work efficiency of load and improve load qualification rate.
The utility model lab scale effect shows, and its effect is well-content.
