The ejector pin seat is used for fixing and placing an ejector pin, when the suction nozzle sucks the chip, the chip is firstly ejected out by the ejector pin, the chip is separated from the bearing film, and then the chip is sucked by the suction nozzle, so that the whole chip is sucked.
However, when the ejector pin is ejected, the carrier film and the chip are not easily separated, so that the chip is not easily sucked by the suction nozzle.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a slice ejector pad seat increases base adsorption area, can reduce the area of contact of chip and membrane, solves the problem that the chip absorbs the chip difficulty at the suction nozzle that the in-process of jack-up appears.
In order to solve the technical problem, the utility model provides a sheet-shaped ejector block seat, which comprises a fixed seat, a sheet-shaped ejector block, an adsorption groove and an adsorption hole;
the top surface of the fixed seat is provided with a plurality of through holes, and the flaky top blocks are correspondingly arranged in the through holes;
and the periphery of the through hole is provided with an adsorption groove and adsorption holes.
Furthermore, the bottom surface of the fixing seat is provided with a supporting frame, and the supporting frame is provided with an open slot.
Furthermore, the through holes are arranged on the top surface of the fixed seat in order, and the shapes of the through holes correspond to the sizes and the shapes of the flaky top blocks.
Furthermore, lubricating oil is arranged between the outer wall of the flaky top block and the inner wall of the fixed seat.
Furthermore, the upper surface of the flaky top block and the top surface of the fixed seat are positioned on the same horizontal plane.
Compared with the prior art, the utility model discloses following beneficial effect has at least:
the contact area between the chip and the film can be reduced by increasing the adsorption area of the base; meanwhile, the sheet-shaped top block is ejected out, the bearing film above the sheet-shaped top block is pre-separated from the chip, and the contact area between the chip and the film is reduced, so that the effect that the chip is smoothly sucked by the suction nozzle above the chip is achieved.

Detailed Description
The sheet-like top block seat of the present invention will now be described in greater detail with reference to the schematic drawings in which preferred embodiments of the invention are shown, it being understood that those skilled in the art may modify the invention herein described while still achieving the advantageous effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
The invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in a very simplified form and are not to precise scale, which is only used for the purpose of facilitating and clearly explaining the embodiments of the present invention.
As shown in fig. 1, fig. 2 and fig. 3, an embodiment of the present invention provides a sheet-shaped top block seat, which includes a fixing seat 1, a sheet-shaped top block 2, an adsorption groove 3 and an adsorption hole 4;
the top surface of the fixed seat 1 is provided with a plurality of through holes 5, and the sheet-shaped top block 2 is correspondingly arranged in the through holes 5;
and the periphery of the through hole 5 is provided with an adsorption groove 3 and an adsorption hole 4.
In this embodiment, the adsorption grooves 3 and the adsorption holes 4 can reduce the contact area between the chip 9 and the carrier film 10, reduce the adhesion between the chip 9 and the carrier film 10, and facilitate the peeling between the chip 9 and the carrier film 10. The whole sheet-shaped top block 2 moves horizontally upwards to jack up the bearing film 10 and the chip 9 above the sheet-shaped top block 2, the bearing film 10 and the chip 9 are pre-separated in the ejection process, the contact area is reduced, and the chip 9 is sucked away by the suction nozzle 8 above. The flaky top block 2 is successively lowered from two sides to the middle to be horizontal to the top surface of the fixed seat 1.
In particular, the adsorption grooves 3 and the adsorption holes 4 are not limited to this arrangement.
Furthermore, a supporting frame 6 is arranged on the bottom surface of the fixing seat 1, and an open slot 7 is formed in the supporting frame 6. In this embodiment, the opening groove 7 of the support frame 6 can realize stable installation of the sheet-shaped top block seat. When the sheet-shaped top block seats with different specifications are selected, the open grooves 7 are opened to be replaced.
Furthermore, the through holes 5 are regularly arranged on the top surface of the fixed seat 1, and the shape of the through holes 5 corresponds to the size and shape of the flaky top block 2. In this embodiment, the sheet-shaped top block 2 is correspondingly disposed in the through hole 5, and meanwhile, the through hole 5 limits the sheet-shaped top block 2, so that the sheet-shaped top block 2 is ensured to move up and down in the through hole 5, and the phenomenon of inclination is avoided.
Specifically, the through holes are not limited to this arrangement.
Furthermore, lubricating oil is arranged between the outer wall of the flaky ejector block 2 and the inner wall of the fixed seat 1. In the present embodiment, the sheet-like top block 2 can move smoothly in the through hole 5, and the sheet-like top block 2 does not collide with the through hole 5 and deform.
Furthermore, the upper surface of the flaky top block 2 and the top surface of the fixed seat 1 are in the same horizontal plane. In this embodiment, the chip 9 is placed above the sheet-shaped top block 2, and the chip 9 is kept horizontal on the carrier film 9 above the fixing seat 1 in the same plane.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
