Principle of work:
First step: Primary Location.
This process first by rotary work station rotating disk vacuum slot 72 sticking eight chips 111 and transfer, after vacuum slot frame 71 is transplanted on position corresponding above cope match-plate pattern 211, put in conical through-hole 211 by disposable for eight chips 111, described conical through-hole 211 is that chip 111 puts into the centre of cylindric blind hole 222 through hole, adopt conical design, because chip 111 may angle of arrival skew and the situation such as mal-position on vacuum slot 72, because conical through-hole 211 is larger at the large circular opening diameter of cope match-plate pattern 21 upper surface, even if there is the most serious skew in chip 111, also can put in conical through-hole 211, when vacuum slot sticking chip 111 enters from large circular open, when the chip 111 of skew moves downward in conical through-hole 211, tapered wall can be subject to more and more extrude, in the process, chip 111 position of skew obtains preliminary corrections, when moving to the small circular opening part of conical through-hole 211, chip 111 position preliminary corrections terminates, now vacuum slot 72 suction disappears, simultaneously under the pull of vacuum effect of aperture 221, chip 111 is just drawn in the cylindric blind hole 222 of lower bolster 22, now chip 111 Primary Location in the cylindric blind hole 222 of described lower bolster 22, the pull of vacuum of aperture 221 disappears, vacuum slot frame 71 rises and resets, because chip 111 is generally rectangle, so the diameter design of cylindric blind hole 222 is become just can hold described chip 111 when designing mould, make chip 111 that the straight-line displacement in other directions can not be able to occur around center rotating in blind hole 222, and the degree of depth of cylindric blind hole 222 is more than or equal to the thickness of chip 111, make chip 111 can not expose the upper surface of described lower bolster 22, this integrated knock hole design is compared with the design of the movable holddown of present technology, precision is higher, and this precision also can not reduce along with mold movement, and existing movable holddown may offset after multiple bearing, precision reduces greatly, must again correct.
After eight chips 111 are by eight border circular areas of Primary Location at lower bolster 22, as Fig. 5, first step completes.
Second step: mould is separated and transfer.
Control system 5 can make slide block 23 be separated with cope match-plate pattern 21 with lower bolster 22 by solenoid control first cylinder 11, and make lower bolster 22 be moved to the left stopping immediately below the first bracing frame 30, the center one_to_one corresponding of the position of eight vacuum slots 312 herein on the first bracing frame 30 and eight cylindric blind holes 222 of lower bolster 22, as Fig. 2, now second step is complete.
Third step: finally locate.
In this process, camera 4 to immediately below lower bolster 4 to take pictures imaging, and image is sent to control system 5, after control system 5 receives image, carry out image procossing, and extract the angle position feature of image chips 111, compare with standard value, and calculate the angle departing from standard value of each chip 111, finally angle parameter is converted to electric signal to be sent to eight stepping motors 311 and to carry out rotation correction, control system 5 controls the second driver train 32 by Controlling solenoid valve subsequently, first bracing frame 30 is pressed down, eight vacuum slots 312 are abutted and adsorbs the center-point of described eight chips 111, although eight chips 111 angle in cylindric blind hole 222 is different, as Fig. 5, but the Central Symmetry point of rectangular dies 111 is all positioned on the central axis of blind hole 222, utilize this character of rectangle, as long as eight vacuum slots 312 face the central axis of blind hole 322, be easy to the Central Symmetry point of absorption chip 111 and chip 111 is rotated in blind hole 222, eight stepping motors 311 drive eight corresponding angles of each spinning of vacuum slot 312, chip 111 so just can be made to correct on all four standard angle angle value, as Fig. 6, now third step is complete, whole process terminates.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
