Description
technical field
The utility model relates to a kind of camera installation, particularly relates to a kind of superposing type voice coil motor.
Background technology
As shown in Figure 1 and Figure 2, the voice coil motor commonly used comprises yoke plate 1 ', upper cover 2 ', upper shell fragment 3 ', magnet 4 ', lower gasket 5 ', coil 6 ', support 7 ', lower shell fragment 8 ', terminal 9 ' and lower cover 10 '.Traditional production technology is points three sections and assembles, that is, leading portion semi-finished product assembling, the assembling of stage casing semi-finished product and the assembling of back segment semi-finished product.Specifically comprise: on first tool, yoke plate 1 ', upper cover 2 ', upper shell fragment 3 ', magnet 4 ' are fitted together, make leading portion semi-finished product; Coil 6 ', support 7 ', lower shell fragment 8 ' fit together by second tool, makes stage casing semi-finished product; Lower gasket 5 ', terminal 9 ', lower cover 10 ' fit together with stage casing semi-finished product by the 3rd tool, makes back segment semi-finished product and assemble with leading portion semi-finished product, making complete VCM product.There is following defect in this assembly technology commonly used:
1, owing to being syllogic assembling, each section all needs a tool, and technological equipment is more, and each section of assembling all can produce certain error, can form larger cumulative errors after each section of rigging error superposition.
2, on the make section semi-finished product time, because lower shell fragment 8 ' needs pre-treatment, and this pre-treatment step is: put glue under (1) between shell fragment 8 ' and lower cover 10 ', send into baking box make it solidify, to reach the effect pre-fixed; (2) shell fragment 8 ' welds with terminal 9 ', and owing to containing rosin in scolding tin, in welding process, there is the problem of easy quick-fried tin, once quick-fried tin, tin sweat(ing) can splash down at internal mechanism, affects component start, reduces yields.After welding is good, also need lower gasket 5 ' to load onto, also need a glue in the process, whole assembling process needs a large amount of some glue to fix, and waits for that glue regular time is longer, inefficiency.
3, in each operation circulation process, also needing to wait for that other semi-finished product make after one section of semi-finished product makes could assemble, and production efficiency is low, needs to use a large amount of UV glue to pre-fix in waiting process, and cost is higher.
Utility model content
The purpose of this utility model is the superposing type voice coil motor providing a kind of precision higher.
