Abstract

The utility model discloses a micro focal spot 3D (three-dimensional) imaging based objective table for CT (computed tomography), which comprises a base, a fixing frame and an objective support table, wherein the fixing frame is vertically fixed onto the base, and the objective support table is partially and fixedly arranged on the fixing frame. The fixing frame is further provided with a Z-axis lifting mechanism capable of vertically moving and being positioned on the fixing frame, the objective support table comprises a tray, a carbon fiber fixing board, a movable cover board, an annular gear upper cover board and an annular gear are sequentially arranged above the tray from top to bottom, and a carbon fiber board for holding a detected object is detachably fixed on the carbon fiber fixing board. The objective table has the advantages that an imaging system is used for large-area SMT (surface mounted technology) check analysis and large-plane object CT imaging and is also the fastest imaging structure, welding conditions of components after PCB (printed circuit board) SMT in large area can be quickly imaged under the condition of planar rotation, and tasks which cannot be completed by traditional computed tomography are completed.

Description

CT based on little focal spot 3D imaging uses objective table

Technical field

The utility model relates to a kind of detection system, and particularly a kind of CT based on little focal spot 3D imaging uses objective table.

Background technology

Utilizing X ray to make the detected material fast imaging accomplish inspection in quality of welding spot detection method commonly used at present analyzes; But during to large tracts of land PCB SMT inspection analysis and imaging; Under the situation of plane rotation, be difficult to imaging rapidly; Common check system can't make the checked property perfect imaging, and causes situation such as regional area flase drop and false retrieval, influences work efficiency and product quality.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of CT based on little focal spot 3D imaging to use objective table, and this system provides multivariant object image-forming method, makes object image-forming more accurate, has accelerated the detected material image taking speed simultaneously.

The utility model for the technical scheme that solves its technical matters and adopt is: a kind of CT based on little focal spot 3D imaging uses objective table; It comprises that base, the fixed mount and the partial fixing that vertically are fixed on the base are arranged on the loading saddle on the fixed mount; Also be provided with one on the said fixed mount and can vertical moving be positioned Z axle elevating mechanism on the fixed mount; Said loading saddle comprises pallet, and the pallet top is disposed with carbon fibre fixed head, removable cover ring gear upper cover plate and ring gear from top to bottom, detachably is fixed with one on the said carbon fibre fixed head and supplies to place the carbon fiber board that detects thing; Said ring gear comprises outer tooth disk and interior fluted disc; Outer tooth disk is fixed on the pallet, and interior fluted disc is provided with the gear teeth and with respect to the outer tooth disk axial rotation, pallet be provided with one with the wheel disk drive device of tooth mesh; Said ring gear upper cover plate piecemeal activity is arranged on the top of the Z axle elevating mechanism that can drive its vertical displacement movement; Said ring gear upper cover plate X axis both sides are provided with first linear guides; And removable cover along the X axis both sides can X to slip be embedded with first linear guides on; The axial both sides of said removable cover Y are provided with second linear guides, and the carbon fibre fixed head along the axial both sides of Y can Y to slip be embedded with second linear guides on.

As the further improvement of the utility model, to being respectively arranged with the guide rail drive unit, said guide rail drive unit comprises: ball screw, shaft coupling, motor and holder along X, Y in the below of said pallet.

The beneficial effect of the utility model is: this imaging system is used for large tracts of land SMT inspection analysis and big planar object CT imaging; Also be imaging arrangement the most efficiently, it can make welding situation imaging soon under the situation of plane rotation of the components and parts behind the big plane P CB SMT; Solved the traditional CT impossible mission; 360 degree rotations when ring gear provides the CT imaging.
