The wave-soldering pallet

Technical field

The utility model relates to and is used for printed board is placed on the pallet that crest welder carries out wave-soldering.

Background technology

At present, from the reliability of wave-soldering technology and the compactedness requirement of printed board design, wave-soldering technology has been adopted in increasing printed board.Printed board is being placed in the process of carrying out wave-soldering in the crest welder; Usually need use pallet; Its concrete structure comprises: supporting plate; Offer several welding windows on the supporting plate, the edge that each welding window is relative is provided with the step of shelving that matches with the appearance and size of corresponding printed board, and supporting plate is respectively arranged with several printed board hold down gags in the both sides of each welding window; Supporting plate is provided with the retaining frame around welding window, the both sides, bottom surface of supporting plate are provided with the step of shelving that matches with the delivery track of crest welder.In actual production process, because supporting plate is not general, and the appearance and size of printed board is not quite similar, and makes that the kind of pallet is more and more, has increased the making maintenance cost of pallet, has increased production cost; In order to reduce the making maintenance cost of pallet, make that pallet can be multiplexing, just must unified appearance and size be processed in various printed boards, so just restricted the design of printed board, make to design and have to sacrifice some costs and performance sometimes.In fact, along with the continual renovation of product, partial tray also can be scrapped along with the stopping production of relevant printed board.

The utility model content

The utility model technical problem to be solved is: a kind of basic framework is general can to reduce the wave-soldering pallet of making maintenance cost thereby provide.

For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the wave-soldering pallet, comprise upper and lower pallet, and following pallet comprises bottom plate; Offer down welding window on the bottom plate; Be respectively arranged with the step of shelving that matches with the appearance and size of mounting plate on the relative edge of following welding window, the both sides of bottom plate are respectively arranged with several mounting plate hold down gags, the both sides, the back side of bottom plate be respectively arranged with crest welder on conveying match shelve step; Described top tray comprises mounting plate; Offer welding window on several on the mounting plate; Be respectively arranged with the step of shelving that matches with the appearance and size of corresponding printed board on the edge that welding window is relative on each, mounting plate is respectively arranged with several printed board hold down gags in the both sides of each welding window.

Described bottom plate is provided with the retaining frame around following welding window.

Described top tray hold down gag comprises: be fixed on the following housing screw on the bottom plate, be set with spring and following pressure strip on the following housing screw; Described printed board hold down gag comprises: be fixed on the last housing screw on the mounting plate, be set with spring and last pressure strip on the last housing screw.

Described pallet down or retaining frame are provided with the printed board hold down gag.

Described printed board hold down gag comprises: be fixed on the housing screw on bottom plate or the retaining frame, be set with elastic spring on the housing screw.

Be provided with spring between described elastic spring and the housing screw.

The beneficial effect of the utility model is: the described pallet of the utility model; Following pallet as its basic framework can multiplexingly need not change; What possibly change is and the closely-related top tray of concrete printed board; And the manufacturing cost of top tray is less than 1/3rd of following pallet, thereby greatly reduces the making maintenance cost, reduced production cost.
