Description

SMT three-proofing paint spraying jig

Technical Field

The utility model relates to a circuit board technical field that sprays paint especially relates to SMT three proofings tool that sprays paint.

Background

The three-proofing paint is a paint with a special formula and is used for protecting a circuit board and related equipment from being corroded by the environment. The three-proofing paint has good high and low temperature resistance; after being cured, the coating becomes a layer of transparent protective film which has excellent insulating, damp-proof, anti-creeping, shockproof, dustproof, anti-corrosion, anti-aging, corona-resistant and other performances.

The paint spraying jig in the prior art is inconvenient for quick clamping of circuit boards, and can not be used for adaptively adjusting and clamping circuit boards of different sizes, and the jig is only suitable for one circuit board and has low universality.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that exists among the prior art, and the SMT three proofings tool that sprays paint that proposes to solve the problem that exists among the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

SMT three proofings tool that sprays paint, including the base upside sets up two closing device at least, closing device includes the back shaft, the joint support board is rotated to the back shaft upper end, the backup pad middle part is equipped with the spout, sliding connection slider in the spout, the slider middle part is equipped with the slide opening that runs through, sliding connection inserted bar in the slide opening, inserted bar lower extreme fixed connection boss, fixed connection supporting spring between boss and the slider.

Preferably, the slider is i-shaped.

Preferably, the boss is a rubber block, and the lower end of the boss is conical.

Preferably, the upper end of the inserted bar is fixedly connected with a pull ring.

Preferably, the upper side of the sliding block is provided with a through threaded hole, and the threaded hole is connected with a locking bolt in a threaded fit mode.

Preferably, the upper side of the base is fixedly connected with two positioning plates, and the two positioning plates are perpendicular to each other.

The utility model has the advantages that: the utility model provides a SMT three proofings tool that sprays paint, backup pad move in the spout around back shaft rotation and cooperation slider, can be to the position of not unidimensional circuit board adjustment inserted bar to after the adjustment is accomplished, extrude at the base upside through the locking bolt, lock the slider, pull up the pull ring, place the circuit board and loosen the pull ring behind the base upside, corresponding locating hole is adjusted well to conical boss, and the clamping of accomplishing the circuit board is fixed.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

As shown in FIGS. 1-3, the utility model provides a SMT three-proofing paint spraying jig, which comprises a base 1, at least two pressing devices 2 are arranged on the upper side of the base 1, the two pressing devices are used for pressing positioning holes on two corners on the diagonal of a circuit board, each pressing device 2 comprises a supporting shaft 21, the upper end of the supporting shaft 21 is rotatably connected with a supporting plate 22, the middle part of the supporting plate 22 is provided with a chute 23, a sliding block 24 is connected in the chute 23 in a sliding way, the sliding block 24 is I-shaped, the upper side of the sliding block 24 is provided with a through threaded hole, the threaded hole is connected with a locking bolt 4 in a matching way, the middle part of the sliding block 24 is provided with a through sliding hole, an inserting rod 25 is connected in the sliding hole in a sliding way, the upper end of the inserting rod 25 is fixedly connected with a pull ring 3, the lower end of the inserting rod 25 is fixedly connected with a, the position of the inserted rod 25 can be adjusted according to circuit boards with different sizes, and after the adjustment is completed, the inserted rod is extruded on the upper side of the base 1 through the locking bolt 4 to lock the sliding block 24; like this when the clamping, only need pull ring 3 to be pulled up, place the circuit board at base 1 upside back release pull ring 3, corresponding locating hole is adjusted well to conical boss 26, the clamping of accomplishing the circuit board is fixed, two locating plates 5 of fixed connection are still gone up to base 1 upside, two locating plates 5 mutually perpendicular set up, when the fixed line board, the circuit board passes through locating plate 5 and tentatively fixes a position, adjusts corresponding inserted bar 25's position afterwards to realize quick adjustment and clamping.

When using, backup pad 22 rotates around back shaft 21 and cooperates slider 24 to remove in spout 23, can adjust the position of inserted bar 25 to the not unidimensional circuit board to after the adjustment is accomplished, extrude the upside at base 1 through locking bolt 4, lock slider 24, pull-up pull ring 3, place the circuit board and loosen pull ring 3 behind base 1 upside, corresponding locating hole is adjusted well to conical boss 26, and the clamping of accomplishing the circuit board is fixed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
