Then, manipulator 61 orders about top camera 81 and draw frame machine 62 moves to this service position, the end face of the chip 200 on top camera 81 pairs of charging trays 214 identifies and locates, this chip 200 is sent to chip positioning mechanism 51 by chip suction nozzle 6211 from absorption chip 200 on charging tray 214 by the suction nozzle 621 of draw frame machine 62, now pre-pressure head drives cylinder 623 not work, chip positioning mechanism 51 vacuum suction is with fixed chip 200, filming-drawing mechanism 52 matches to even up with the pressure head 32 of diaphragm feeding device 30 output strains diaphragm 400, film cutting machine structure 53 cuts off by the diaphragm 400 of evening up according to the instruction of controller, squeeze-film mechanism 54 is drawn the diaphragm 400 after being cut off and is pressed to by this diaphragm 400 and fits with the chip 200 at place of chip positioning mechanism 51, chip positioning mechanism 51 in the horizontal direction movement coordinates squeeze-film mechanism 54 to realize successively to the pad pasting of two chips 200, thus realize the laminating of diaphragm 400 and chip 200.
Meanwhile, support 300 is one group with 6 and installs in support carrier 310, multiple support carrier 310 transmits successively on transmission guide rail 41, when be located at laminating station 41a place sensor sensing to support carrier 310 time, the pushing tow cylinder being positioned at laminating station 41a bottom according to the instruction of controller moves upward, and makes this support carrier 310 upwards jack-up extremely disengaging transmission guide rail 41.
Then; manipulator 61 orders about the motion that the suction nozzle 621 of draw frame machine 62 and pre-pressure head 622 do straight line and rotation, send the chip after laminating 200 and diaphragm 400 to support 300 place of laminating station 41a by the suction nozzle 621 moved by chip suction nozzle 6211 and the corresponding suction of diaphragm suction nozzle 6212.In transport process, identify by the bottom surface of bottom camera 82 pairs of chips 200 and locate, in conjunction with top camera 81 pairs of supports 300 identification and location with the placement location adjusting chip 200.When the height of distance bracket carrier 310 is 0.1mm; pre-pressure head drives cylinder 623 to order about pre-pressure head 622 and does rectilinear motion to abutting against with diaphragm 400; manipulator 61 continues to order about suction nozzle 621 and pre-pressure head 622 moves downward; make diaphragm 400 be close on support carrier 310, chip 200 is crimped on support 300.Manipulator 61 orders about draw frame machine 62 and repeats above-mentioned action, 6 chip 200 correspondences is transmitted on 6 supports 300 successively.Then, be positioned at the hot-pressing point of electric heating iron 71 above laminating station 30a hot pressing 6 chips 200 successively under the driving of heater travel mechanism 72, make the hot melt adhesive layer of support 300 be melted to liquid state from solid-state, realize chip 200 with this and fit with the hot pressing of support 300.
Finally, after having fitted, according to the instruction of controller, pushing tow cylinder moves downward, and makes the support carrier 310 at laminating station 41a place continue to transmit.
Compared with prior art, the chip 200 after pad pasting by after chip 200 surface laminating diaphragm 400, then conforms on support 300 by chip attachment machine 100 of the present utility model.First; chip feeding device 20 and diaphragm feeding device 30 are positioned at the same side of carriage conveyor 40; chip transfer apparatus 60 is between chip feeding device 20 and diaphragm feeding device 30; film sticking apparatus 50 is between chip transfer apparatus 60 and diaphragm feeding device 30, and hot-press arrangement 70 is positioned at the top of the support of transmission.Wherein, chip 200 and diaphragm 400 are bonded to each other under the cooperation of chip transfer apparatus 60 and film sticking apparatus 50; after pad pasting; chip 200 fits on the support 300 that carriage conveyor 40 transmits by hot-press arrangement 70 hot pressing under the driving of chip transfer apparatus 60; complete machine structure is simple and compact; decrease the movement travel at attachment process chips conveyer 60, also need not set up other transporting apparatus again, correspondingly reduce cost.Secondly, in attachment process, to the attachment of the attachment of chip 200 and diaphragm 400 and chip 200 and support 400 all by the identification of industrial camera 80 with locate to realize accurate attachment, improve attachment efficiency, effectively ensure that the accuracy of attachment.Moreover, because diaphragm 400 has been pasted on chip 200 surface, not only solve the air spots of attachment process chips 200 and the problem of collsion damage.And the more important thing is the crushing resistance that improve chip 200, effectively achieve harmless attachment.Finally, the laminating of chip 200 and support 300 realizes the laminating between chip 200 and support 300 by the hot pressing of hot-press arrangement 70.Therefore, again it can be transmitted by support carrier 310 in carriage conveyor 40 after gluing is first carried out to support 300 in outside, improve attachment efficiency with this.During laminating, only the PUR of curdled appearance need be liquefied by hot-press arrangement 70 and can realize the laminating of chip 200 and support 300.Thus chip attachment machine 100 of the present utility model does not need to put glue and attachment in real time to chip 200 or support 300, therefore the equipment such as set-point adhesive dispenser, glue amount control device is not needed, further simplify complete machine structure, also simplify technique, effectively reduce cost.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
