Description

Springboard is prevented in intensive mechanical drilling

Technical Field

The utility model relates to a processing technology field is chewed to the drill, specifically is a springboard is prevented in intensive mechanical drilling.

Background

In PCB board production process, often need see at the multiply wood and carry out high density and punch, especially BGA current leads when passing through the hole site, can break the PCB base plate because the jump pin, consequently more broken PCB board can appear in high density drilling process, can beat the crackle because the jump pin on the product even, when the product dispatches from the factory and carries out secondary operation or use, appears breakage to influence product quality.

For example, according to the technical scheme disclosed in the patent of a battery protection PCB (patent No. CN201620925510), intensive hole sites are punched in a mode of combining multiple punching and layered punching, although the qualification rate of the PCB is ensured to a certain extent, the loss of machinery is aggravated due to the increase of punching frequency, and the production efficiency is directly reduced.

Disclosure of Invention

The utility model provides a springboard is prevented in intensive mechanical drilling in order to solve the problem of the needle jump of punching among the prior art.

In order to solve the technical problem, the utility model discloses a following technical scheme:

The utility model provides an intensive mechanical drilling springboard, includes top plate, locating hole, blotter and fixed plate, the fixed plate lower surface is fixed with the PCB board, is equipped with the top plate on the fixed plate, be equipped with the locating hole on the top plate, be equipped with the space between top plate and the fixed plate, set up the blotter between top plate and the fixed plate.

Further, the number of the cushion pads is more than or equal to 4.

Furthermore, the fixed plate is a good thermal conductor, so that heat can be conveniently transferred out and then discharged.

The upper plate is provided with dense positioning holes which are communicated with each other.

The buffer cushion is of an elastic structure.

The buffer pad slides between the upper plate and the fixing plate, and the position of the buffer pad between the upper plate and the fixing plate changes along with punching.

A gel layer is arranged between the fixing plate and the PCB, and the thickness of the gel layer is within the range of 0.1mm-0.35 mm.

Intensive locating hole on the upper plate can assist and prevent that the springboard carries out the radiating while, can prevent the cracked accident of PCB board because of the jumper pin leads to.

It is visible by above technical scheme, the utility model discloses following beneficial effect has:

1. The utility model discloses simple structure, simple to operate sets up the gel layer owing to be close to one side of PCB board, not only can the shock attenuation, can also keep being connected with the PCB board.

2. The utility model discloses the probability of the time leap needle can effectively be reduced and punch can reduce the damaged probability of PCB board.

3. The utility model discloses use and processing and relevant trade.

Drawings

In order to more clearly illustrate the technical solutions of the present invention or the prior art, the drawings used in the following description will be briefly described, and it is obvious for those skilled in the art that other drawings can be obtained without creative efforts.

Fig. 1 is a schematic structural diagram provided by the present invention.

Wherein: 1. an upper plate; 2. positioning holes; 3. a cushion pad; 4. and (7) fixing the plate.

Detailed Description

In order to make the technical solutions in the present invention better understood, the following description of the present invention with reference to the accompanying drawings will be made clear and fully descriptive of the technical solutions in the present invention, and it is obvious that the description is only a part of the present invention, not all of it. Based on the utility model provides a, all other that ordinary skilled in the art obtained under the prerequisite of not making the creative work all should belong to the scope protected by the utility model.

Example 1

Referring to fig. 1, an intensive mechanical drilling anti-jumping plate includes an upper plate 1, a positioning hole 2, a cushion pad 3 and a fixing plate 4, wherein a lower surface of the fixing plate 4 is fixed to a PCB, the fixing plate 4 is provided with the upper plate 1, the upper plate 1 is provided with the positioning hole 2, a gap is formed between the upper plate 1 and the fixing plate 4, and the cushion pad 3 is disposed between the upper plate 1 and the fixing plate 4.

The number of the cushion pads 3 is more than or equal to 4, the fixing plate 4 is a good thermal conductor, the upper plate 1 is provided with dense positioning holes 2, the positioning holes 2 are communicated with each other, and the cushion pads 3 are of elastic structures.

The buffer pad 3 slides between the upper plate 1 and the fixing plate 4, the buffer pad 3 changes along with the punching position between the upper plate 1 and the fixing plate 4, a gel layer is arranged between the fixing plate 4 and the PCB, and the thickness of the gel layer is within the range of 0.1mm-0.35 mm.

To sum up, compared with the prior art, the utility model, have simpler structure and more convenient operation process, can effectively avoid the problem of jump needle.

Example 2

The buffer pad 3 slides between the upper plate 1 and the fixing plate 4, the buffer pad 3 changes along with the punching position between the upper plate 1 and the fixing plate 4, a gel layer is arranged between the fixing plate 4 and the PCB, and the thickness of the gel layer is 0.25 mm.
