Abstract:
The present invention relates to a nozzle and adjust module of chemicals when wafers are processed during the IC manufacturing process. After wafers are loaded on a chuck of a reaction chamber, five chemicals required for the manufacturing process are transported into the passages, and are sprayed on the surfaces of rotating wafers via different nozzles. The centrifugal effect due to the rotation of a main motor is exploited to coat the chemicals on the whole wafer quickly and uniformly. The present invention can apply to both closed and open reaction chambers. The spray head of the present invention has a specially designed angle, and has level adjusting and height adjusting functions so that high flexibility in the manufacturing process can be obtained.
Abstract:
An adjustment and automatic inward-contraction and outward-expansion machanism, and particularly a single mechanism that provides the function of variable specification adjustment as well as automatic inward-contraction and outward-expansion of the claw arms during operation is described. The mechanism includes a worm provided for driving the worm gear and other related devices in rotation so that a cylindrical groove cam is engaged in motion up and down. With the cylindrical groove cam in motion up and down and further by means of L-type steering block, push and pull rod and four-bar linkage, claws are provided for specification adjustment. During the operation of the machine and when the roller of the plunge rod under L-type steering block is in rotation along the groove of the cylindrical groove cam, due to the undulations of groove, the plunge rod is in motion up and down and causes the contraction and expansion of the claw arms by means of the L-type steering block, the push and pull rod and the four-bar linkage, so as to meet the requirement of expanding the mouth of the bag and the operations prior to the sealing treatment. The present mechanism not only can adjust the distance between the claw arms subject to the specification of the bag directly by means of the worm but also can perform the function of automatic contraction and expansion of the claw arms when the bag is properly located at a specific position so as to cooperate with the external structure for the preformance of expanding the mouth of the bag, charging the bags and the thermal sealing treatment.
Abstract:
A method and apparatus for unclosing and enclosing the flaps of a package carton, so that cartons can be transported along the transportation path without shifting backward or shifting away from the transportation path. The method consists of (a) disposing a package carton on a first transportation slab with the opening of the package carton facing downward; (b) continuously guiding the package carton in the longitudinal direction of the first transportation slab; (c) folding the leading first flap in an upward and forward direction, and guiding the leading first flap to lap on a second transportation slab, then urging the lagging first flap to lap on the second transportation slab; (d) folding the second pair of flaps to trap the second transportation slab between the opening of the package carton and the second pair of flaps; (e) guiding the second pair of flaps to skip from underneath the second transportation slab and to lap on a third transportation slab; (f) folding the leading first slap in a downward and backward direction to trap the third transportation slab between the opening of the package carton and the leading first flap, and guiding the leading first flap to lap on a fourth transportation slab; (g) folding the lagging first flap in a downward and forward direction to trap the fourth transportation slab between the opening of the package carton and the lagging first flap; and (h) guiding the lagging first flap to lap on a fifth transportation slab.

Abstract:
A vacuum apparatus of rotary motion entry is disclosed, which comprises: a shaft sleeve, disposed on a cavity wall of a vacuum system; a rotary shaft, ensheathed by the shaft sleeve; and a transmission set, connected to the rotary shaft for driving the same; wherein, the rotary shaft is disposed passing through a hole formed on the base of the shaft sleeve while there are a first bearing, a second bearing, a sealing ring and a shaft seal being arranged separately inside the hole. Moreover, the shaft seal has a flake-like lip flange formed extending toward the center of the hole, that is capable of being extended away from the vacuum system by the inserting of the rotary shaft into the hole, and thereby, enabling the lip flange to engage with the rotary shaft tightly by the atmospheric pressure and thus isolating the outside world from the vacuum system.
