Description
Technical field
The foot device for being used for SOP chips on a kind of CD writers is the utility model is related to, belongs to recording device technical field.
Background technology
SOP is encapsulated（Small Out-Line Package）IC chip using surface mount formats encapsulate, be to popularize most
Extensive surface mount package, pin centre-to-centre spacing 1.27mm, number of pins are 8~44, are widely used in electronics industry.
Last procedure of the pin forming of SOP chips as encapsulation, is typically completed using special forming jig
's.At present, as electronic product develops towards frivolous direction, in actual production process, sometimes according to customer demand, it is necessary to
The SOP chips for having completed packaging process are done into the adjustment of further pin, it is existing to form the chip that thickness after paster can be smaller
Have in technology also without such adjusting apparatus.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided is used for SOP cores on a kind of CD writers
The foot device of piece, chip pin can be adjusted while burning, to form the smaller chip of thickness after paster.
According to technical scheme provided by the utility model, the foot device of SOP chips, its feature are used on the CD writers
It is：Including track, installation base pressure bar is arranged in rail base, is feeding position of the chip in track directly over base pressure bar；
Left and right sides vertical sliding sets overhead gage above the track, and the top of overhead gage sets stopping means；In the track
Pin pressing plate is fixed in the left and right sides respectively, and the end of pin pressing plate is extended in track；When chip injection, the left and right sides
Pin pressing plate stretch into the length of track and cover the chip pins of chip both sides, also, when chip is moved to most on base pressure bar
During height, the lower surface of pin pressing plate and the plastic body of chip are generally aligned in the same plane.
Further, the pin pressing plate is stretched into by mounting hole installed in the left and right sides of track with adjustment pin pressing plate
Length in track.
Further, it is provided for blocking the chip baffle plate of chip on front side of the base pressure bar.
Further, the rear and front end of the overhead gage wears guide rod respectively, and guide rod is slidably matched with overhead gage, guide rod
Top sets stopping means.
Further, spring is set between the stopping means and overhead gage.
Further, the stopping means uses limited cap.
It is used for the foot device of SOP chips on CD writers described in the utility model, is filled by installing presser feet on CD writers
Put, chip pin can be adjusted while burning, to form the chip that thickness after paster can be smaller, so as to reach client
Demand, the device is simple to operate, can greatly simplify process, reduces production cost.

Fig. 2 is Fig. 1 side view.
Fig. 3 is Fig. 1 top view.
Fig. 4 is the base pressure bar raised state schematic diagram.
Description of reference numerals：1- limited caps, 2- guide rods, 3- springs, 4- overhead gages, 5- pins pressing plate, 6- chip pins, 7-
Plastic body, 8- base pressures bar, 9- chips baffle plate, 10- tracks, 11- chips.
Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
In the description of detailed description below, coordinate reference Fig. 1, using the left and right directions in Fig. 1 as left and right, above-below direction
To be upper and lower, after the direction of vertical paper inwardly is, before the direction of vertical paper outwardly is.
As shown in FIG. 1 to 3, the foot device of SOP chips, including track are used on CD writers described in the utility model
10, installation base pressure bar 8 is arranged in the bottom of track 10, is feeding position of the chip 11 in track 10 directly over base pressure bar 8；Institute
State the top of track 10 left and right sides and overhead gage 4 is set, the rear and front end of overhead gage 4 wears guide rod 2, guide rod 2 and overhead gage 4 respectively
It is slidably matched, the top of guide rod 2 sets limited cap 1, and spring 3 is set between limited cap 1 and overhead gage 4；In the track 10
Pin pressing plate 5 is fixed in the left and right sides respectively, and the end of pin pressing plate 5 is extended in track 10, when 11 injection 10 of chip,
The length that the pin pressing plate 5 of the left and right sides stretches into track 10 covers the chip pin 6 of the both sides of chip 11, also, works as chip 11
When being moved to maximum height on base pressure bar 8（When i.e. overhead gage 4 contacts with limited cap 1）, lower surface and the chip 11 of pin pressing plate 5
Plastic body 7 be generally aligned in the same plane.
In order to adapt to the work of the presser feet of different chip pins 6, the pin pressing plate 5 can be arranged on track by mounting hole
10 left and right sides, the distance stretched into by mounting hole come adjustment pin pressing plate 5 in track 10, to ensure the chip of different length
Pin 6 can be pressed onto the plastic body same plane with chip 11 by pin pressing plate 5 well, smaller so as to obtain thickness after paster
Chip.
In addition, it is provided for blocking the chip baffle plate 9 of chip 11 in the front side of the base pressure bar 8.
Operation principle of the present utility model：Chip 11 is slipped to pin pressing plate 5 by upper track 10 and kept off by chip baffle plate 9
Firmly, base pressure bar 8 withstands chip 11 and overhead gage 4 from chip 11 is bottom up, and chip 11 de-orbits 10 bottom up movements
So that chip pin 6 contacts with fixed pin pressing plate 5, continue up top and be pressed onto chip pin 6 and the plastic body of chip 11
Same plane, so as to form a kind of smaller chip of thickness after paster.
