The described cross section wearing silk rod 50 is wavy setting, namely arranges in multiple continuous print W shape; The front and back width wearing silk rod 50 is corresponding with the length of described porcelain tube 11; End face and the bottom surface of wearing silk rod 50 are provided with some spaced holddown grooves 51, the V-shaped setting of the cross section of holddown groove 51 in the present embodiment, and the holddown groove 51 of the end face and bottom surface of wearing silk rod 50 shifts to install; Understandably, this wears the handle that silk rod 50 also comprises side.
Below, by introducing the manufacture method of this SMD fuse, described for making using method and the effect thereof of the tool of SMD fuse to describe; The manufacture method of this SMD fuse comprises the steps:
Step one, cap in pressure; Described porcelain tube 11 and two shrinkage pool caps 14 are provided, by each shrinkage pool cap 14 respectively with the two ends pressing of porcelain tube 11; Particularly, as shown in Figure 4, described porcelain tube 11 is arranged in hollow, roughly in rectangular-shaped; The two ends size of porcelain tube 11 reduces and forms stage portion; The middle part of porcelain tube 11 is provided with the cavity 110 running through two ends; Each shrinkage pool cap 14 is arranged in square lid, comprise cover plate 140 and from cover plate 140 periphery towards the vertically extending side plate 141 of porcelain tube 11, the center of this cover plate 140 is provided with circular perforation 145, cover plate 140 from perforation 145 peripheries towards porcelain tube 11 stretch flange formability 146;
In the present embodiment, as shown in Figure 5, porcelain tube 11 and the bonding processes of shrinkage pool cap 14 are by cap presser 20 auto-stitching; This cap presser 20 comprises porcelain tube transport way 21, first cap transport way 22, second cap transport way 23, rolling disc 24 and finished product Efferent tube 25.One end of described porcelain tube transport way 21 connects a porcelain tube charging tray (not shown), other end connection of rotating dish 24; The top of the first cap transport way 22, second cap transport way 23 connects a charging tray 26 respectively, and each charging tray 26 is built with described shrinkage pool cap 14;
Described rolling disc 24 is placed in vertical direction, and namely the central shaft of rolling disc 24 extends in the horizontal direction.The two ends of this rolling disc 24 connect a mount pad 27 respectively, and this rolling disc 24 is arranged on mount pad 27 by rotating shaft 240.The middle part of rolling disc 24 is provided with central channel 245 annularly spaced apart, and the end of corresponding described porcelain tube transport way 21 is arranged to receive the porcelain tube 11 that porcelain tube transport way 21 transmits; The left and right sides of rolling disc 24 each central channel 245 corresponding arranges storage tank 248 respectively, described storage tank 248 rotates Moving plate 24 circumferentially-spaced, and the bottom of corresponding first cap transport way 22, the second cap transport way 23 of difference, to receive the shrinkage pool cap 14 that the first cap transport way 22, second cap transport way 23 transmits.Described storage tank 248 is provided with thimble 29 away from the part of described central channel 245.Be provided with cam structure (not shown) in described mount pad 27, this cam structure is connected with described thimble 29;
When rolling disc 24 outwards rotates, when central channel 245 runs to below porcelain tube transport way 21, receive porcelain tube 11; Storage tank 248 receives shrinkage pool cap 14 when running to the below of the first cap transport way 22, second cap transport way 23; Then, rolling disc 24 rotates towards finished product Efferent tube 25, the promotion that thimble 29 in storage tank 248 is subject to cam structure is made and being reciprocated, thus the shrinkage pool cap 14 in storage tank 248 is pressed to porcelain tube 11 two ends of central channel 245, thus the two ends of porcelain tube 11 and shrinkage pool cap 14 are fastened; The porcelain tube 11 completing cap in pressure flows out from central channel 245 through finished product Efferent tube 25;
Step 2, wears fuse; Use described eyelet strip 40, the porcelain tube 11 being pressed into shrinkage pool cap 14 in step one is placed on eyelet strip 40; Rock eyelet strip 40, make porcelain tube 11 fitly be arranged in embedded groove 41; Wherein, because porcelain tube 11 is in rectangular-shaped, the side angle lapping of porcelain tube 11 snaps in embedded groove 41 backward, and the top of embedded groove 41 can avoid porcelain tube 11 to be retained in position between adjacent embedded groove 41 well; When porcelain tube 11 is fitly arranged in after in each embedded groove 41 of eyelet strip 40, ready fuse 13 is passed porcelain tube 11 and the shrinkage pool cap 14 of alinement in embedded groove 41.Understandably, whole porcelain tubes 11 can be put on by a fuse 13, also fuse 13 can wear porcelain tube 11 in an embedded groove 41 in other embodiments;
Step 3, around wearing silk rod; The porcelain tube 11 completing threading is wrapped in and wears on silk rod 50, make all roughly concordant with the front-back wearing silk rod 50 setting in the two ends of all porcelain tubes 11;
Step 4, welds a cap; Electric iron and scolding tin are provided, the same side of the porcelain tube 11 worn on silk rod 50 is welded, fuse 13 is welded with the shrinkage pool cap 14 of this end; Particularly, the temperature controlling range of described electric iron is 390 DEG C ~ 450 DEG C; Cool after completing welding;
Step 5, fills with quartz sand; The porcelain tube 11 completing weldering one cap in step 4 is put into ready quartz sand 12, makes one end that porcelain tube 11 does not weld upward, quartz sand 12 is pushed on porcelain tube 11 and cover, quartz sand 12 is entered and fills up porcelain tube 11; Particularly, quartz sand 12 can be pushed on one end that porcelain tube 11 do not weld by instruments such as hairbrush and fill, until cover porcelain tube 11; Understandably, after step 5 end-of-fill, entirely can be examined the porcelain tube 11 of filling with sand by microscope;
Step 6, welds two caps; Electric iron and scolding tin are provided, the one end of not welding completing the porcelain tube 11 of filling with quartz sand is welded; Wear on silk rod 50 because each porcelain tube 11 is still wrapped in, electric iron can weld rapidly;
Step 7, trimming; Exited from wearing silk rod 50 rotation by the porcelain tube 11 completing weldering two cap, now adjacent porcelain tube 11 is linked together by fuse 13; Use pliers to be cut off by the outward extending fuse 13 in each porcelain tube 11 two ends, keep the smooth of two ends scolding tin as far as possible;
Step 8, presses outer cap; Described outer cap 16 is provided, by each outer cap 16 respectively with the two ends pressing of porcelain tube 11 completing trimming; Particularly, the cap presser 20 in step one is used outer cap 16 to be pressed together on the two ends of porcelain tube 11, unlike, the length of the central channel 245 of cap presser 20 is longer than the central channel 245 in step one after adjustment, to adapt to the porcelain tube 11 in completing steps seven.
Seen from the above description, use eyelet strip 40 in the step 2 of the manufacture method of described SMD fuse, use in step 3 to step 6 and wear silk rod 50, processing can be carried out to SMD fuse 10 in bulk, greatly improve the efficiency of manufacture, reduce production cost.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not 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 range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
