Figure 2 is a perspective view illustrating Figure 1 from another perspective; and

Fig. 3 is a schematic side view illustrating the structure of a vacuum holding device and its arrangement in the feeding/discharging base.

The preferred embodiments of this creation will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of this creation can be more easily understood by those skilled in the art, so as to make a clearer definition of the protection scope of this creation.

Referring to Fig. 1 and Fig. 2, it is a preferred embodiment of the feeding/discharging base 2 of the present invention. The feeding/discharging base 2 is installed on a machine platform. Multiple inlet/discharge bases2. Since the structure of the machine is not the focus of this case, it will not be shown or described in detail here.

Referring to FIG. 1 to FIG. 3 , the loading/discharging base 2 includes a base body 3 and a vacuum holding device 4 disposed in the base body 3 . The seat body 3 has a top surface 301, a bottom surface 302 opposite to the top surface 301, a through hole 31 penetrating the top surface 301 and the bottom surface 302, and at least one vacuum groove 32 penetrating the top surface 301 and the bottom surface 302 .

The vacuum holding device 4 is disposed in the base body 3 and adjacent to the vacuum groove 32 . Referring to Fig. 3, the vacuum holding device 4 includes a fixing seat 41 arranged in the through hole 31, a sliding rod 42 longitudinally passing through the fixing seat 41 and capable of sliding relative to the fixing seat 41, and a ring sleeved on the fixing seat 41. The slide bar 42 and the elastic member 43 clamped between the slide bar 42 and the fixing seat 41, and the through hole 31 which is arranged on the top of the slide bar 42 and partially protrudes from the inlet/discharge base 2 and the rolling element 44 on the top surface 301 .

More specifically, the through hole 31 of the base body 3 has a large aperture end 311 and a small aperture end 312 with a smaller aperture than the large aperture end 311, and the fixing seat 41 of the vacuum holding device 4 is arranged on the through hole. The large aperture end 311 of the hole 31 . The fixing seat 41 has an axially extending through hole 411 , and the sliding rod 42 is disposed in the through hole 411 . Wherein, the sliding rod 42 has a rod body part 421 that can slide in the piercing hole 411 of the fixing seat 41, and a rod body part 421 arranged on the rod body part 421. The plate body portion 422 is located in the small diameter end 312 of the through hole 31 .

The elastic member 43 is looped around the body portion 421 of the sliding rod 42 and clamped between the body portion 422 and the fixing base 41 . The rolling element 44 is arranged on the plate body portion 422 , the plate body portion 422 of the slide bar 42 has a recessed area 423 for positioning the rolling element 44 , and the rolling element 44 passes through the small-diameter end 312 Partially protrudes from the through hole 31 and the top surface 301 . Through the above arrangement, when the rolling member 44 is pressed down from above, it can move slightly downward, simultaneously pressing down the plate body portion 422 of the sliding rod 42 , and then making the elastic member 43 accumulate elastic restoring force. When the pressure disappears, the elastic restoring force of the elastic member 43 will push up the plate body portion 422 of the sliding rod 42 to make the rolling member 44 return to its original position.

For existing automation equipment for packaging or testing electronic components, a plurality of electronic components (not shown) will be installed at intervals on the periphery of a turntable 9, and the turntable 9 will drive the described Electronic components move. As shown in Figure 3, when the turntable 9 moves to a proper position, the gas will be sucked through the vacuum groove 32 on the seat body 3 of the inlet/discharge base 2, so as to suck or blow out the electronic components. Turntable 9. Through the arrangement of the vacuum holding device 4, when the machine is pumped through the vacuum groove 32, the rolling member 44 can support the turntable 9, so that the edge end of the turntable 9 will not be attracted and attached to the base 3's top surface 301, so it can prevent the turntable 9 from closing the vacuum groove 32 because it is attached to the top surface 301, so that the vacuum groove 32 can continue to pump air, thereby achieving the effect of maintaining vacuum.

In addition, since the rolling member 44 can roll relative to the slide bar 42 and is not fixedly arranged on the plate body portion 422 of the slide bar 42, when the turntable 9 rotates, even if it contacts the rolling member 44, the rolling The part 44 can rotate along with the movement of the turntable 9, and there will not be too much friction between the two, so the movement of the turntable 9 will not be affected.

As can be seen from the above description, the design of the loading/discharging base 2 of the present invention through the design of the vacuum holding device 4 can keep the turntable 9 and the machine at an appropriate distance, so that the turntable 9 can be drawn by the machine when the machine is vacuumed. The rolling member 44 supports the top, so that the edge of the turntable 9 will not be attracted downward and attached to the machine table or the feeding/discharging base 2, thereby maintaining the effect of vacuum pumping and keeping the turntable 9 rotating smoothly.

The above implementation methods are only to illustrate the technical conception and characteristics of this creation. Its purpose is to let people familiar with this technology understand the content of this creation and implement it.
