Description
Technical field
The utility model relates to circuit board mounting technology field, especially a kind of antistatic the turn of the screw work for circuit board
Dress.
Background technique
As the design of circuit board and chip is more and more accurate, becomes increasingly complex, the requirement to circuit board ESD protection is also got over
Come higher, especially in automobile industry, for standard requirements in the assembling process of circuit board, human body cannot directly contact circuit board, need
Carry out complete anti-static precautions.
Currently, the fixed mode on the shell of circuit board, most of still to make to be screwed, robot the turn of the screw is used
If fixation, puts into larger and different product and need to be arranged different program and cutter head, general medium-sized and small enterprises are difficult to hold
By, thus at present the turn of the screw process mostly or by manually being operated, installation standard requirements direct labor must dress prevent it is quiet
Electric hand protector just can be carried out operation.However, direct labor dresses antistatic hand since the screw of fixed car circuit board is generally smaller
Placing screws and the turn of the screw operation cannot be carried out after set well, so that production efficiency is low.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of stubborn spiral shell of the antistatic used for circuit board assembly
Silk tooling under conditions of meeting ESD protection requirement, can be rapidly completed the placement and the turn of the screw operation of screw, improve work
Make efficiency.
In order to solve the above technical problems, technical solution adopted in the utility model is as follows.
A kind of antistatic the turn of the screw tooling for circuit board, including flat insulating substrate, insulating substrate correspond to PCB
The position of screw hole offers for being oriented to screw, is tightened up a screw hole with guaranteeing that screw can vertically fall into shell on circuit board
Targeting port, offer component in several embedded PCB circuit boards on the bottom face that insulating substrate and PCB circuit board fit
Groove.
A kind of above-mentioned antistatic the turn of the screw tooling for circuit board, the insulating substrate are soft insulating substrate.
A kind of above-mentioned antistatic the turn of the screw tooling for circuit board, the targeting port includes being coaxially disposed from top to bottom
The top perisotomice diameter of upper conical pilot hole and inferior pyramidal pilot hole, the upper conical pilot hole is greater than bottom perisotomice diameter, under
The bottom perisotomice diameter of conical pilot hole is greater than top perisotomice diameter, and the bottom perisotomice diameter and inferior pyramidal of upper conical pilot hole are led
Top perisotomice diameter to hole is equal and is all larger than the diameter that the diameter of screw rod on screw is less than screw upper cap nut, and inferior pyramidal is led
It is greater than the height of screw nut to the height in hole and is lower than the length of screw rod.
Due to using above technical scheme, technological progress acquired by the utility model is as follows.
The utility model is applied in the assembling process of circuit board, can be avoided direct labor and directly contacts circuit board, has
Effect reduces static electricity on human body's damage caused by circuit board, and can guarantee that screw rapid vertical is placed on above positioning port,
Fast and easy the turn of the screw operation, substantially increases production efficiency.
Detailed description of the invention
Fig. 1 is the top view of the utility model；
Fig. 2 is the side view of the utility model；
Fig. 3 is the schematic diagram under the utility model use state.
Wherein: 1. toolings, 11. insulating substrates, 12. upper conical pilot holes, 13. inferior pyramidal pilot holes, 14. grooves, 2.PCB
Circuit board, 3. shells, 4. components, 5. screws, 6. screw holes, 7. screwdrivers.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
A kind of antistatic the turn of the screw tooling for circuit board, structure is as depicted in figs. 1 and 2, including flat exhausted
Edge substrate 11, insulating substrate are made using antistatic insulating soft material, the mountable PCB to be installed of the shape of insulating substrate
The shape of circuit board is made, so that human body will not touch circuit after guaranteeing that insulating substrate is covered in PCB circuit board
Plate.
The position that insulating substrate corresponds to screw hole in PCB circuit board 2 offers targeting port, for being oriented to screw, with
Guarantee that screw can vertically fall into the screw hole on shell 3；It is opened on the bottom face that insulating substrate 11 fits with PCB circuit board 2
Equipped with several grooves 14, component for being embedded in PCB circuit board is avoided in the mistake by PCB circuit board installation on the shell
Component is squeezed in journey.
The effect of targeting port is smoothly to make screw vertically into the screw hole top to shell, to reach this purpose, guiding
Mouth is arranged for structure as shown in Figure 2, specifically: including the upper conical pilot hole 12 being coaxially disposed from top to bottom and inferior pyramidal
Pilot hole 13；The top perisotomice diameter of upper conical pilot hole 12 is greater than bottom perisotomice diameter, is put into screw to facilitate；Inferior pyramidal is led
It is greater than top perisotomice diameter to the bottom perisotomice diameter in hole 13, to guarantee that screw can be screwed into place；The bottom of upper conical pilot hole 12
The top perisotomice diameter of portion's perisotomice diameter and inferior pyramidal pilot hole 13 is equal, and the diameter for being all larger than screw rod on screw is less than screw
The diameter of upper cap nut, the height of inferior pyramidal pilot hole 13 are greater than the height of screw nut and are lower than the length of screw rod, be used for
Guaranteeing can be perpendicular to screw hole after screw is put into.
When the utility model is used, reeded end face is arranged in insulating substrate first to place downward on circuit boards, so
Screw is put into targeting port afterwards, in the process, need to guarantee the nut of screw upward, screw rod downward.Not to screw
When applying active force, because targeting port inside diameter is less than head diameter, screw is just fixed, while guaranteeing screw face spiral shell
Silk mouth can guarantee screw in power at this point, carrying out the turn of the screw operation using screwdriver because tooling material is soft materials
Continue decline under effect and reach screw hole, and rotate into and tighten, achievees the purpose that circuit board being fixed on shell.
