Description

Electronic component conveying method and device

The present invention relates to a conveying method and device, and more particularly, to an electronic component conveying method and device for conveying electronic components by a turntable.

Generally speaking, after the manufacture of electronic components such as passive components or LED components, they usually need to undergo testing, sorting and packaging procedures. These equipment for testing, sorting and packaging are often equipped with multiple containers around the periphery. The turntable of the slot is used to transport electronic components. The turntable is intermittently rotated against the machine table, and the electronic components are accommodated in the container to be transported; when the turntable rotates intermittently, the The electronic components in the container will rub against the machine table, which will not only damage the electronic components, but also cause scratches on the machine table after a period of use.

In order to reduce the above-mentioned deficiencies, the technology disclosed in the Bulletin No. I563585 "Method and Device for Handling Electronic Components" was developed, which uses the first negative pressure suction force and the second negative pressure suction force to suck the electronic components against the grooves of the turntable. The inner edge is pressed against the pressing sheet above the turntable to reduce the friction caused by the contact between the bottom of the electronic component and the table top of the machine.

In the conventional technology disclosed in Announcement No. I563585 "Method and Device for Handling Electronic Components", when handling electronic components, the negative pressure suction only attracts the side of the electronic components facing the inner edge of the container, resulting in the electronic components not being adsorbed. The other side may still be affected by gravity and fall into contact with the machine table, especially when handling electronic components with heavy weight, this is more likely to happen.

In other words, an object of the present invention is to provide a method for conveying electronic components that can reduce the contact between the electronic components and the machine table.

Another object of the present invention is to provide an electronic component conveying device which can reduce the contact between the electronic component and the machine table.

Please refer to FIGS. 2 and 3 , the turntable B and the cover C are both disc-shaped and have the same outer diameter. The turntable B can be driven by a driver (not shown) to link the cover C to the machine synchronously. The table A is rotated intermittently in the counterclockwise direction, and after receiving the electronic components W sent from a feeding channel D, the container B1 transports the electronic components W through the intermittent rotating flow path; The machine table A is provided with a ring-shaped restricting piece E, which is arranged on the periphery of the turntable B and the cover C and surrounds the container B1, so as to prevent the electronic components W from being transported during the conveying process. It is thrown out of the container B1 by centrifugal force; the restricting piece E is provided with a feeding section E1 with no space and no enclosure for the feeding channel D to be connected to the container B1; the restricting piece E is another There is a discharge section E2 with no space and no enclosure for the electronic components W to discharge the container B1; the rotation of the turntable B makes the container B1 move from the feed section E1 to the discharge section E2. The rotation angle is greater than 180 degrees; A ring-shaped top cover F is disposed above the restricting piece E, the inner diameter of which is smaller than the outer diameter of the cover C, so that a part of the top cover F covers the top of the cover C.

Please refer to FIG. 3 , the air groove A1 is concave downward from the machine table A to form a circular ring with a hollow section A11, and is horizontally arranged on the upper surface of the machine table A. The hollow section Section A11 corresponds to the feeding channel D; the outer diameter of the air channel A1 is smaller than the outer diameter of the turntable B and the air channel A1 is set between the outer edge B11 of the container B1 and the inner edge B12 of the container B1 ; The width of the recessed area of this air groove A1 on the machine table A is less than the length and width of the electronic component W, so that the electronic component W will not drop in the air groove A1; the air groove A1 and the A plurality of first air holes A2 on the machine table A that can pass through the positive pressure communicate with each other, and the first air holes A2 are arranged in the air groove A1 at a fixed distance.
