Technical field

The utility model relates to a kind of board, particularly a kind of surface adhering technology (Surface Mounted Technology that is applied to; SMT) board.

Background technology

Because the volume of electronic installation is more and more littler, function becomes increasingly complex, and makes that the circuit board volume in the electronic installation also must dwindle thereupon, also represents the parts density on the circuit board more and more higher simultaneously, and the assembling difficulty is more and more higher.Therefore surface adhering technology (Surface MountedTechnology has appearred; SMT) realize the configuration and the assembling of high density part.

In existing SMT flow process, can utilize carrier to come the bearer circuit plate usually, and then utilize this carrier to carry out follow-up processing procedure.Because SMT has and easily is automated, advantage such as enhance productivity and reduce cost, so SMT has become the mainstream technology of part assembling on the present circuit board.

Please see figures.1.and.2 simultaneously, Fig. 1 is the schematic side view of the part-structure of existing SMT board 10, and Fig. 2 is the schematic diagram of the conveyer belt of existing SMT board 10.After conveyer belt 12 was delivered to trading halt district 16 with circuit board 14, transport platform 18 up moved, and comes bearer circuit plate 14 so that carrier 20 passes the openwork part 22 of 12 of conveyer belts.Because conveyer belt 12 is controlled by board 10, therefore, circuit board 14 is positioned at the position in trading halt district 16 and can accurately controls.Yet, because existing SMT board 10, for example: SMT piece machine CM402 or by the British businessman get can the manufacturing of (DEK) company stencil printer, the positioning function of carrier 12 on transport platform 18 is not provided itself, when carrier 12 is positioned over position on the transport platform 18 when deviation occurring, the process of carrier 12 bearer circuit plates 14 will have problems, for example: gap (gap) can appear in 14 of carrier 12 and circuit boards, cause the carrier 12 can't bearer circuit plate 14, or carrier 12 strikes the part on the circuit board 14, and part is damaged.

Present way is the range estimation that relies on the staff, checks whether the position that carrier 12 is placed on the transport platform 18 correctly corresponds to the position that circuit board 14 is positioned at trading halt district 16.But so way not only needs a large amount of time, and reliability is not high yet

Therefore, need a kind of new board, use that accurately carrier is positioned on the transport platform.

The utility model content

The technical problems to be solved in the utility model provides a kind of surface adhering technology board (SMT board), has accurately and locating effect fast, and can reduce because the location damage part incidence that inaccuracy caused.

The technical scheme that its technical problem that solves the utility model adopts is: the utility model proposes a kind of SMT board, this board comprises at least: transport platform and carrier, and wherein transport platform has a plurality of location hole, and carrier is in order to carrying and fixation workpiece.Above-mentioned carrier has a plurality of angles, the size of these angles and location hole coupling.When carrier was placed on the transport platform, angle can insert the location hole, so that carrier is fixed in the default working region of transport platform.

Described SMT board is a SMT piece machine, perhaps is a stencil printer.

The surface of described workpiece is covered with a plurality of electronic components, and the surface of described carrier has a plurality of spaces of mating with those electronic components.

The beneficial effects of the utility model are to utilize the angle of carrier and the location hole on the transport platform to carry out carrier location, reaching accurately and locating effect fast, and reduce because the location damage part incidence that inaccuracy caused.The utility model can increase the accuracy of carrier location, reduces the required time of carrier location, therefore production line can be changed the time of carrier, is reduced to 18 minutes from originally 58 minutes, decreases the part ratio and then drops to 0.037% by 0.4%.
