[0015] A method for using a fully automatic eutectic bonding device comprises the following steps:
[0016] Step 1: Place the coated base at the top center of the base platform, place the chip at the bottom of the pneumatic suction cup, the chip pushes the clamping plate, the clamping plate drives the card plate to move, the card plate drives the reset spring to stretch, and the air pump is started at the same time. Through the settings of the suction pipe, the connecting ring, and the pneumatic suction cup, the chip is adsorbed, and through the settings of the exhaust pipe, the conversion box, the vertical pipe, and the elastic rope, the piston drives the magnetic block to move down, the magnetic block drives the magnetic ring to move down, the magnetic ring drives the cross block to move down, the cross block drives the limit shell to move down, the cross block drives the diamond ring to move down, and the diamond ring drives the connecting ring to move down, thereby solving the problem of inaccurate positioning during chip patching;
[0017] Step 2: When the magnetic block descends, it drives the round rod to move downward. During the downward movement of the round rod, it touches the rotating plate. The untouched end of the rotating plate moves upward, so that the rotating plate pushes the square plate to rise. The square plate drives the track block to rise. The track block drives the connecting block to rise. The connecting block drives the elastic plate to rise. During the rising process of the elastic plate, it comes into contact with the vibration spring, causing the vibration spring to reciprocate. The vibration spring drives the base to reciprocate, thereby solving the problem of bubbles inside the adhesive on the base.
[0018] Step three: the limiting shell and the clamping plate move downward at the same time, the clamping plate drives the chip to fall, the limiting shell and the clamping plate enter the inside of the card slot, the base platform moves downward under force, the base platform drives the connecting column to move downward, the connecting column drives the slider to move downward, the slider drives the extrusion plate to move downward, the extrusion plate squeezes the airbag, and the setting of the airbag, condensation plate, venting pipe, diffusion bucket, diamond ring, connecting frame, and elastic tube is used to solve the problem of uneven cooling process.
[0019] The present invention has the following beneficial effects:
[0020] (1) In the present invention, the limit shell and the clamping plate move downward at the same time, the clamping plate drives the chip to fall, and the limit shell and the clamping plate enter the interior of the card slot, thereby enhancing the accuracy of the chip during solidification. Because the magnetic block drives the magnetic ring to move downward, the extrusion force between the chip and the base is generated based on the magnetic connection between the magnetic block and the magnetic ring, thereby preventing the extrusion force from being too large and damaging the chip and the base, thereby enhancing the protection effect of the device.
[0021] (2) In the present invention, the coated base is placed at the top center of the base platform, and the chip is placed at the bottom of the pneumatic suction cup. The chip pushes the clamping plate, and the clamping plate drives the card plate to move. The card plate drives the reset spring to stretch, thereby strengthening the device's clamping and stabilizing effect on the chip. The air pump is started, and the air pump generates suction that enters the interior of the connecting ring through the suction pipe. The suction enters the interior of the pneumatic suction cup through the connecting ring, so that the pneumatic suction cup adsorbs the chip. At the same time, the other end of the air pump is exhausted, and the airflow enters the interior of the conversion box through the exhaust pipe. The airflow enters the interior of the vertical pipe through the conversion box and pushes the piston, which drives the magnetic block to move downward, which drives the magnetic ring to move downward, which drives the cross block to move downward, and the magnetic ring slides on the outside of the vertical pipe, and the cross block drives the limit shell to move downward, which drives the diamond ring to move downward, and the diamond ring drives the connecting ring to move downward, thereby enhancing the stability during the falling process, and the base platform is always penetrated by the vertical pipe, so that the base on the base platform and the chip during the falling process can be always in an aligned state, thereby enhancing the alignment accuracy during the device patch.
[0022] (3) In the present invention, when the magnetic block descends, it drives the round rod to move downward. During the downward movement of the round rod, it touches the rotating plate. The end of the rotating plate that is not touched moves upward, so that the rotating plate pushes the square plate to rise. The square plate drives the track block to rise. The track block drives the connecting block to rise. The connecting block drives the elastic plate to rise. During the rising process of the elastic plate, it comes into contact with the vibration spring, causing the vibration spring to reciprocate. The vibration spring drives the base to reciprocate. During this vibration process, bubbles can be discharged from the inside of the adhesive, thereby enhancing the compactness of the adhesive and improving the quality between the cured chip and the base.
[0023] (4) In the present invention, the base platform is squeezed, the base platform drives the connecting column to move downward, the connecting column drives the slider to move downward, the slider drives the extrusion plate to move downward, and the extrusion plate squeezes the airbag. Due to the setting of the condensation plate, the cold air flow inside the airbag enters into the diffusion bucket through the vent pipe, thereby cooling the bottom of the base during the curing process. At the same time, the diamond ring drives the connecting frame to move downward, and the connecting frame drives the elastic tube to move downward. Due to the setting of the condenser, the cold air flow enters into the elastic tube through the conversion box, and cools the top of the chip during the curing process, thereby expanding the cooling range during the curing process and enhancing the quality of the base and the chip during the curing process.
[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
