The specific embodiment
Present embodiment has disclosed a kind of wave-soldering fixture, comprises carrying the pallet 110 of LED lamp plate and in order to compress the cover plate 120 of LED lamp plate.On LED lamp plate, array is placed with several LED lamp bodies, during use, on LED lamp plate, and LED lamp body and LED lamp plate is positioned between pallet 110 and cover plate 120 the vertical array arrangement of LED lamp body.Please refer to the drawing 1 to Fig. 4 has disclosed the structural representation of pallet 110.The hollow out flat board 112 that pallet 110 comprises tray frame 111 and is positioned at tray frame 111 bottoms.
Please refer to the drawing 5 has disclosed the upward view of cover plate 120.Cover plate 120 is provided with the LED through hole 121 of array arrangement, and when LED lamp body and LED lamp plate are positioned between cover plate and pallet, each LED lamp body can be corresponding one by one with above-mentioned LED through hole 121.Thereby guarantee that LED lamp body can be perpendicular on LED lamp plate in welding process.In addition, the side wall surface of cover plate 120 is outward extended with lug, in tray frame 111, depression has the groove 1111 matching with lug, when cover plate 120 is pressed on pallet 110 by LED lamp plate, lug close-fitting is in the groove corresponding with it 1111, LED lamp body is contained in LED through hole 121 inside, and the center line of LED lamp body overlaps with the center line of LED through hole 121.Said structure, in welding process, can be guaranteed the perpendicularity between LED lamp body and LED lamp plate effectively.
Lug has the first lug 122, second lug 123, the first lugs 122 relative with the first lug 122 have different overall dimensions from the second lug 123.Meanwhile, in tray frame 111, also depression has the groove 1111 matching with the first lug 122 and the second lug 123.The lug with different overall dimensions only can be pressed in the groove 1111 matching with it, thereby make the installation between pallet 110 and cover plate 120 there is foolproof function, effectively reduced LED lamp body that the setup error due to pallet 110 and cover plate 120 the causes deflection problem on LED lamp plate.
Please refer to the drawing 2, is also provided with shell fragment 130 in the tray frame 111 of present embodiment, and shell fragment 130 has stiff end 131 and free end 132, and stiff end 131 is bolted with tray frame 111.Please refer to the drawing 7, has caved inward on cover plate 120 and has pressed hole 124, and when cover plate 120 covers on pallet 110 by LED lamp plate, free end 132 is pressed on hole 124.Thereby guarantee the compression dynamics between pallet 110 and cover plate 120.
Between tray frame 111 and hollow out flat board 112, be also provided with LED lamp plate bearing frame 113, LED lamp plate can be carried on LED lamp plate bearing frame 113.In order to ensure the stable of LED lamp plate, fix, LED lamp plate bearing frame 113 caves inward and is useful on the deep gouge 1134 of carrying LED lamp plate in the one side towards tray frame 111.On the sidewall of LED lamp plate bearing frame 113, be penetrated with several tin grooves 1131 of leading.By being penetrated with several tin grooves 1131 of leading on the sidewall at LED lamp plate bearing frame 113, the scolding tin of melting is when welding section, can allow scolding tin be back to wave soldering tin bath by leading tin groove 1131, and this structure can play water conservancy diversion to the scolding tin of melting, thereby improved the welding uniformity of the pin of each LED lamp body on LED lamp plate, and can reduce on the pin that excessive scolding tin is trapped in LED lamp body, thereby cause the generation of short circuit problem.
Hollow out flat board 112 is provided with the FX 1121 of fixing above-mentioned LED lamp plate bearing frame 113 and the hollow out region 1122 that is positioned at FX 1121 inside.FX 1121 can have any shape according to the shape of LED lamp plate, and in present embodiment, FX 1121 is rectangle.On hollow out region 1122, have several the first ribs 11221 that are parallel to each other and with perpendicular several the second ribs 11222 of the first rib 11221, wherein, the first rib 11221 is parallel with one side of FX 1121.Between each root first rib 11221, formation supplies the weld groove that the scolding tin of melting flows through.Be parallel on the cross section of hollow out flat board 112, the area that LED lamp plate bearing frame 113 contains is less than the area in hollow out region 1122.LED lamp plate bearing frame 113 has caved inward and has led tin step 1132 in the one side towards hollow out flat board 112, and in present embodiment, LED lamp plate bearing frame 113 is along there is a pair of relative tin step 1132 of leading perpendicular to depression on the direct of travel of wave-soldering fixture.When wave-soldering fixture enters into scolding tin district, tin ripple drags tin welding along the weld groove of LED lamp body pin, by what cave inward at LED lamp plate bearing frame 113, lead tin step 1132 and can allow tin ripple when dragging tin, play cushioning effect, lead the tin step 1132 of leading that tin step 1132 is relative and when dragging tin, be unlikely to directly to cut off scolding tin and leave node with above-mentioned, avoid the company's of generation tin bad phenomenon when entering tin and dragging tin.
By the above-mentioned setting of leading tin groove 1131 and leading tin step 1132, can significantly reduce LED lamp body failure welding rate, improve the welding quality of LED lamp body pin.In addition in a pair of opposing sidewalls of LED lamp plate bearing frame 113, be also extended with laterally respectively for hand-held hand-held lug 1133.
Fig. 5 to Fig. 8 has also disclosed other structure of present embodiment cover plate 120.Cover plate 120 is provided with several for locating the locating dowel 125 of LED lamp plate in a close side of pallet 110, thereby guarantees that LED lamp body and LED lamp plate can accurately be positioned between pallet 110 and cover plate 120, has effectively guaranteed the perpendicularity of LED lamp body welding.Cover plate 120 is fixedly connected with handle 126 in the side away from pallet 110.In addition, cover plate 120 is provided with several for by the demoulding through hole 127 of the LED lamp plate demoulding, thereby facilitates the smooth demoulding of LED lamp plate.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
