In the figure: the device comprises a cover plate 1, a through groove 2, a connecting block 3, a bottom plate 4, a positioning seat 5, a supporting column 6, a fixing block 7, a supporting frame 8, a supporting plate 9, a positioning column 10, a positioning sleeve 11, a cover plate 12, an LC filter 13 and a sealing groove 14.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-5, a brush soldering paste device of LC filter closing cap board, including bottom plate 4, be provided with apron 1 through positioning mechanism on the bottom plate 4, a plurality of logical grooves 2 have been seted up on the apron 1, through 7 fixedly connected with connecting block 3 of fixed block in the logical groove 2, connecting block 3 is the same with logical groove 2 profile, it forms the clearance to lead to between groove 2 and the connecting block 3, through putting into well LC filter 13 with closing cap board 12, make seal groove 14 coincide with the clearance, scribble the soldering paste on apron 1 again, the soldering paste can enter into seal groove 14 from the clearance, the temperature that puts into the time of going back to the stove case and corresponds seals the welding and accomplishes again, can weld a plurality of LC filters 13 simultaneously, be favorable to raising the efficiency, compare with manual welding, the welded is effectual, it is more pleasing to the eye.

A plurality of positioning seats 5 of fixedly connected with on the apron 1, positioning seat 5 are located logical groove 2 under, through the design that adopts positioning seat 5 to play the effect of location when placing LC filter 13, prevent the removal.

Positioning mechanism includes reference column 10, position sleeve 11, the equal fixedly connected with position sleeve 11 in both ends of bottom plate 4, the equal fixedly connected with reference column 10 in both ends of apron 1, and in reference column 10 can insert into position sleeve 11, through the design that adopts reference column 10 and position sleeve 11, plays spacing effect to apron 1 to make seal groove 14 coincide mutually with the clearance.

All fixedly connected with support column 6 all around of apron 1 through the design that adopts support column 6, plays the effect of support to apron 1.
