Specific embodiment
In order to illustrate more clearly of the present invention, the present invention is done further below with reference to preferred embodiments and drawings
It is bright.Similar component is indicated in attached drawing with identical appended drawing reference.It will be appreciated by those skilled in the art that institute is specific below
The content of description is illustrative and be not restrictive, and should not be limited the scope of the invention with this.
The present invention provides a kind of localization methods of support pin of printed circuit board, include the following steps:
1) template is made
As shown in Figure 1, production one piece of template 1 identical with printed circuit board to be produced, the geomery of template 1 with it is to be generated
Production printed circuit board is identical, or chooses the finished product printed circuit board scrapped or make identical with printed circuit board to be produced
Experimental plate is exemplarily.
2) locator is made
As in Figure 2-4, a columnar locator 2 is made, the internal diameter of locator 2 is equal or slightly larger than 3 bottom of thimble
The height of the outer diameter of seat, locator 2 is greater than the distance between template 1 and thimble fixed station 4.Thimble 3 is stepped shaft structure, including
Pedestal diameter lesser support end and be relatively large in diameter, support end and pedestal are coaxially disposed.
3) supporting point is determined
The position of supporting point and quantity are pre-set, with printed circuit board to be produced part placement position phases
It adapts to, supporting point needs to avoid the sensitizing ranges such as component and measuring point, and reserved safe spacing 1mm.That is, according to be generated
The components' placement of printed circuit board is produced to determine position and the quantity of supporting point, the position of supporting point will meet apart from supporting point
Component and measuring point are not provided in 1mm radius, the quantity of supporting point can guarantee thimble to the firm branch of printed circuit board
Support.
4) location hole is opened up
Location hole 11 is opened up by the center of circle of supporting point in template 1, the diameter of location hole 11 is equal or slightly larger than locator 2
Outer diameter.
5) thimble is placed
Template 1 is put into track, is transmitted in printing machine, then locator 2 is inserted into location hole 11, makes locator 2
Bottom is contacted with the surface of thimble fixed station 4, is then put into thimble 3 inside it from the top of locator 2, thimble 3 is along positioning
The inner surface of device 2 slides down to the surface of thimble fixed station 4, and is absorbed and fixed at top by the magnet on 3 pedestal of thimble
On needle fixed station surface, finally extracts locator 2 and be inserted into next positioning hole, whole thimbles 3 are successively placed into thimble and are consolidated
Determine the surface of platform 4.
6) template is taken away
After whole thimbles 3 are in place, take template 1 and locator 2 away, obtain the support pin of printed circuit board of accurate positioning
3。
Since the diameter of location hole 11 is equal or slightly larger than the outer diameter of locator 2, and locator 2 is inserted into location hole 11
Afterwards, the bottom surface of locator 2 contacts fitting with thimble fixed station surface, it is ensured that the axle center of locator 2 and the center of circle weight of location hole
It closes.The outer diameter of 3 pedestal of thimble is equal or slightly larger than due to the internal diameter of locator 2 again, it is ensured that the axis of 3 support end of thimble and fixed
The axis of position device 2 is overlapped, so that the axis of 3 support end of thimble is overlapped with the circle of location hole 11, improves the standard of the positioning of thimble 3
True property.
Thimble 3 is located at the lower section of printed circuit board, and the inner space of printing machine is small, and producers are difficult to put on thimble
To accurate location.Method of the invention can place thimble 3 in the top of template inside the printing machine of internal narrow space,
The operation of personnel easy to produce, while the position of thimble 3 can be accurately positioned prevents thimble 3 from damaging and has mounted on circuit board
Component.
As shown in Figs 1-4, the invention also discloses a kind of positioning devices of support pin of printed circuit board, including template 1
With locator 2.Template 1 is set as identical as the geomery of printed circuit board to be produced, offers on template 1 and is with supporting point
The location hole 11 in the center of circle.Locator 2 is set as columnar structured, and the internal diameter of locator 2 is equal or slightly larger than the outer of 3 pedestal of thimble
Diameter, the outer diameter of locator 2 are equal to or slightly less than the diameter of location hole 11, and the height of locator is greater than template 1 and thimble fixed station 4
The distance between.
Thimble 3 is set as stepped shaft structure in present embodiment, including bottom diameter lesser support end and be relatively large in diameter
Seat, support end and pedestal are coaxially disposed.
As shown in figure 4, locator 2 is inserted into location hole 11, when using positioning device of the invention due to locator 2
Height be greater than the distance between template 1 and thimble fixed station, be bonded the bottom surface of locator 2 and the surface of thimble fixed station 4
Contact, ensure that the axis of locator 2 is overlapped with the center of circle of location hole 11.Then thimble 3 is put into it from the top surface of locator 2
Inside, since the internal diameter of locator 2 is equal or slightly larger than the outer diameter of 3 pedestal of thimble, thimble 3 can be along the inner surface of locator 2
Sliding reaches the surface of thimble fixed station 4, and is absorbed and fixed on thimble fixed station 4 under the magnet effect on 3 pedestal of thimble.
So that operator can place thimble 3 in the top of template 1, and slided by locator 2 positioned at 1 lower section of template
On thimble fixed station 4.Meanwhile template 1 and locator 2 can guarantee that the position of thimble 3 is accurate, reduce conventional printing support pendulum
Put bring risk.
Template 1 can be the finished product printed circuit board scrapped or experimental plate identical with printed circuit board to be produced, into one
Reduce production cost to step.Template 1 is to be made of clear material in the present embodiment, it is preferable that template 1 is by acrylic material
Material is made, and locator 2 is also made of acrylic material, and such structure observes the situation of movement of thimble 3 convenient for operator, improves
The accuracy in place of thimble 3.
Further, the top of locator 2 is equipped with flange 21, and flange 21 is by the outer surface convex shaped at the top of locator
At.Since the outer diameter of flange 21 is greater than the diameter of location hole 11, locator 2 only has one end that can pass through location hole 11,
When taking template 1 away, locator 2 can be taken away together, improve the convenience of this positioning device.
In order to distinguish the direction that template 1 enters printing machine, arrow has been portrayed on 1 surface of template in present embodiment, the arrow
Head is directed toward the traffic direction of template 1, prevents from template direction putting mistake, causes the positional fault of thimble 3.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention may be used also on the basis of the above description for those of ordinary skill in the art
To make other variations or changes in different ways, all embodiments can not be exhaustive here, it is all to belong to this hair
The obvious changes or variations that bright technical solution is extended out are still in the scope of protection of the present invention.
