At first, shown in Fig. 3 and 4, cylinder 28 is fixed on the support member on the sliding support 12 that both sides form, and remains to be arranged on cylinder below 28 with 29 plate that are connected 10 that bond.
At this moment, temperature that produced by bonding 29 apply according to operating conditions differently, and choosing ground is to apply 5～10 seconds kinds within 170 ℃～220 ℃ of temperature ranges.
Secondly, preferably, according to binding material, pressure is 2Mpa, 40kg/cm 2
Bonding 29 vertically moves along slide rail 46 slidably by operation cylinder 28.
Fig. 5 and 6 illustrates the front view and the planimetric map of countertop unit.One milling clamp 32 is assembled on the tabular platform 31, and video camera 47 is assembled on the platform support 30, thus operator's state of sight glass 52, binding material 53 and chip for driving 45 bondings constantly.
Fig. 7 and 8 illustrates the planimetric map and the side view of chip delivery unit.The chip pin 37 fixedly critical component at place (key) (not shown) is fixed on another plate 10 and adsorbs the chip for driving 45 that leaves among the robot cell 48 under vacuum condition, and the edge is displaced sideways by operation cylinder 28 simultaneously.After this, this critical component is automatically moved to the bonding head, so that be adsorbed under vacuum condition.The chip delivery unit is turned back to its initial position by cylinder 28 and falls.After this, the operator then, is bonded in chip for driving 45 on the glass surface of placing on the countertop unit 49 by the position of video camera 47 adjusting chip delivery units.
Fig. 9 and 10 is illustrated in the robot cell's who operates on the X-Y axis front view and planimetric map.Connect plate 42 can be by being rotationally connected with ball-screw 39 on the electric machine support 44 lateral rotation.
Secondly, a plurality of chip for driving 45 are positioned to connect on the plate 42 and by chip delivery unit 50 and transmit.
At this moment, employing by as thermoplastic resin family by polystyrene resin, ethene acetic acid ester resin (EVA) or ethene acetyl resin, perhaps by the binding material of making as phenolic resin, urea resin, melanocyte resin, alkyd resin, vibrin, silicones, epoxy resin, urethane resin or the furancarbinol resin of thermosetting resin family.Binding material closely is applied on glass, and is made it fusing and chip for driving is bonded on glass by the heat of high temperature of heating plate.
More than bonding can be finished by the people unit 48 of operating machine continuously, chip delivery unit 50, countertop unit 49 and bonding head unit 51.
Operation of the present invention and effect will be described as follows in more detail.
At first, the operator is placed on a plurality of chip for driving 45 on the plate 10 of working on the X-Y axis by the ball-screw 39 that manipulation is assembled on the robot cell 48, and waits for next step.
At this moment, being assembled into heating plate 17 and the bonding 29 of bonding on the head unit 51 rises along slide rail 46 by operation cylinder 28.
After this, move into place chip for driving 45 places on plate 10 with the integrally formed casing 19 of chip delivery unit 50 and backing plate 13 by operation cylinder 28.
Then, in chip delivery unit 50, vacuum buffer pad 38 be fixed in connect on the mounting bracket on the rotary driver 36, make chip for driving 45 be adsorbed and move by air supplied in vacuum condition following moment.
The chip for driving that is adsorbed under vacuum condition is moved on the bonding 29 and is adsorbed under vacuum condition, and chip delivery unit 50 turns back to its initial position.
Then, bonder 29 falls by operation cylinder 28.
At this moment, go up and can not move by 52 surfaces because binding material 53 is bonded in glass for chip for driving 45.
Secondly, the operator utilizes X, Y and theta stage to regulate the ITO line (not shown) of impression on the glass 52 and the projection of chip for driving 45, so that they are become is identical by being contained in video camera 47 under the countertop unit 49.After this, when the operator pressed the switch (not shown), slide rail 46 moved backward by operation cylinder 28, and bonding 29 falls, thus hot pressing glass and chip for driving.
Then, after the process official hour, the one action circulation finishes along with bonding 29 rise, and then adhering device turns back to initial position.
Industrial applicability
As mentioned above, structure according to LCD panel of the present invention, the signal that produces between many data lines that are installed on the COG type LCD face glass disturbs and the EMI phenomenon is reduced, and the distortion of the signal that is transmitted via data line and input lead section is minimized.
Though the present invention is described with reference to each concrete illustrated embodiment, it also be can't help embodiment and limits, and is just limited by appended claims.Should be appreciated that those skilled in the art can change or revise embodiment under the prerequisite that does not depart from category of the present invention and spirit.
