Abstract
The utility model discloses a kind of device for being used to eliminate the small clearance display screen out-of-flatnesses of LED, including pcb board, back drill hole, the back drill hole are offered on the pcb board）Circumference on copper post pad is installed, copper post is installed, for the copper post also with copper post pad solder, the bottom of the copper post is dentation on the back drill hole.Its is simple in construction for the utility model, easy for installation, and can ensure copper post will not can so ensure the flatness for shielding body with the contact surface of casing and LED face height because PCB tolerance has influenceed.
Description
Technical field
It the utility model is related to a kind of device for being used to eliminate the small clearance display screen out-of-flatnesses of LED.
Background technology
With the miniaturization of the display device of LED display, the display pixel spacing of display screen is more done smaller, has reached
Below 1mm, so the flatness requirement more and more higher to display screen, too big yet with PCB thickness deviation, flatness is difficult
Reach desirable, so that engineer is in order to make display surface smooth, and the structure for having done many regulations is put down to adjust lamp face
Whole degree, operation are very troublesome.
Utility model content
The purpose of this utility model is to provide a kind of device for being used to eliminate the small clearance display screen out-of-flatnesses of LED, its knot
Structure is simple, easy for installation, and can ensure copper post will not have with the contact surface of casing and LED face height because of PCB tolerance
Influenceed, so can so ensure the flatness for shielding body.
In order to achieve the above object, the technical solution of the utility model is：
It is a kind of to be used to eliminate the devices of the small clearance display screen out-of-flatnesses of LED, including pcb board, offer the back of the body on the pcb board
Drilling, the back drill hole）Circumference on copper post pad is installed, copper post is installed on the back drill hole, the copper post also with copper
Post pad solder, the bottom of the copper post is dentation.
The external diameter of the dentation of the copper post is less than the aperture in back drill hole.
Arc cell body is further opened with the copper post.
10 back drill holes are offered on the pcb board.
The row of 10 back drill holes point 3 are opened on pcb board, and 2 row of wherein PCB both sides open up 3 back drill holes, institute respectively
State and 1 row totally 4 back drill holes are opened up among pcb board.
The beneficial effects of the utility model are：Its is simple in construction for the utility model, easy for installation, can ensure copper post with
The contact surface of casing and LED face height will not can so ensure to shield the smooth of body because PCB tolerance has influenceed
Degree.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of copper post.
Embodiment
Embodiment 1
A kind of device for being used to eliminate the small clearance display screen out-of-flatnesses of LED as shown in Figure 1, including pcb board 1, the pcb board
Offer back drill hole 2 on 1, the depth in back drill hole be more than design structure theoretical size add PCB tolerance and bore process tolerance it
With, copper post pad 3 is installed on the circumference in the back drill hole 2, copper post 4 is installed on the back drill hole 2, the copper post 4 also with
Copper post pad 3 welds, and the bottom of the copper post 4 is dentation.
The external diameter of the dentation of the copper post 4 is more than the aperture in back drill hole 2, copper post is not being damaged the situation of pcb board
It can press on pcb board, and can enough has certain intensity, and copper post is not easy to shift.
Arc cell body 5 is further opened with the copper post 4, the radius of the arc cell body is R0.2, plays the work of protection copper post
With.
10 back drill holes 2 are offered on the pcb board 1.
10 back drill holes 2 divide 3 row to be opened on pcb board 1, and 2 row of wherein PCB both sides open up 3 back drill holes respectively
2,1 row totally 4 back drill holes 2 are opened up among the pcb board, are played uniform difference, are ensured its flatness.
First the back side SMD components attachment welding of LED lamp panel is finished, is then attached to the pcb board for posting component is counter
On smooth platform, copper post is pressed in the pcb with the tool of limit for height with hydraulic cutting presser, then again used copper post and copper post edge pad
Tin welding, the lamp plate for the copper post that pressed is being gone to mount lamp face LED.
A kind of device for being used to eliminate the small clearance display screen out-of-flatnesses of LED of the present embodiment, its is simple in construction, installation side
Just, can ensure copper post will not be because PCB tolerance have influenceed with the contact surface of casing and LED face height, this
Sample can ensure the flatness for shielding body.
