Abstract
The utility model relates to a but work or material rest structure of going up of automatically regulated size, it includes work or material rest base (1), go up and seted up inside and outside multiunit bumping post notch (2) on the work or material rest base (1), be provided with bumping post (3) in bumping post notch (2), bumping post (3) are including last cylinder (31) and lower cylinder (32), cylinder (32) and bumping post notch (2) actuation mutually down. The utility model relates to a but last work or material rest structure of automatically regulated size, its adjustment bumping post position that can be more convenient has improved production efficiency, can avoid because of the product quality that bumping post position control elasticity knob wearing and tearing cause is unusual, has still reduced the encapsulation manufacturing cost in addition.
Description
Technical Field
The utility model relates to a but last work or material rest structure of automatically regulated size is applied to bearing of integrated circuit packaging in-process lead frame, belongs to semiconductor package equipment technical field.
Background
When a semiconductor packaging frame product is packaged, a lead frame needs to be placed on a base of an upper material frame for a chip mounting machine to absorb and then carry out chip mounting operation. The retaining columns on the periphery of the upper material rack base are used for fixing the lead frame to prevent the lead frame from moving, when lead frames of different sizes are replaced, the retaining column tightness knob of the upper material rack needs to be loosened firstly, then the positions of the 6 retaining columns are manually adjusted according to the size of the lead frame, and finally the retaining column tightness knob of the upper material rack is screwed. The above method has the following disadvantages:
1. when lead frames with different sizes are replaced, the positions of 6 stop posts need to be manually adjusted, so that the operation is complicated, and the production efficiency is low;
2. the elastic knob of the material loading rack stop post is easy to wear after being used for a long time, so that the stop post is not fixed tightly, and the frame is deformed abnormally after the lead frame moves.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a but material rest structure on automatically regulated size is provided to above-mentioned prior art, its adjustment bumping post position that can be more convenient has improved production efficiency, can avoid the product quality because of bumping post position control elasticity knob wearing and tearing cause unusually, has still reduced the encapsulation manufacturing cost in addition.
The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a but automatic adjustment size's last work or material rest structure, it includes the work or material rest base of going up, go up the work or material rest base and seted up inside and outside multiunit bumping post notch, be provided with the bumping post in the bumping post notch.
Optionally, the bumping post includes upper column body and lower column body, lower column body and bumping post notch actuation mutually.
Optionally, the upper material rack base is made of iron, and the lower column body is made of a magnet.
Optionally, the upper column is made of aluminum.
Optionally, the upper column body and the lower column body are connected by a connecting screw.
Optionally, the connection screw is a double-thread screw.
Optionally, every group bumping post notch all includes notch, lower notch, left notch and right notch.
Optionally, the number of the upper notch and the lower notch is 2, and the number of the left notch and the right notch is 1.
Compared with the prior art, the utility model has the advantages of:
the utility model relates to a but automatic size regulation's last work or material rest structure, its operation of manual adjustment bumping post position when having cancelled the not unidimensional lead frame of change has improved production efficiency, and has stopped from the design face because of the product quality abnormity that bumping post position control elasticity knob wearing and tearing cause, has reduced encapsulation manufacturing cost.
