Description

Technical Field

[0001] This application relates to the technical field of RFID die bonding production, and in particular to a six-position rotary pickup and bonding device for wafers. Background Technology

[0002] With the continuous development of technology, the demand for RFID chip bonding is also increasing. RFID chip bonding generally consists of an antenna of 10-30 micrometers and an IC chip connected to the antenna feed point. RFID chip bonding can store relevant information and usually uses radio signals. When the tag receives the signal, it returns the signal to the reader, and the reader reads the information in the tag.

[0003] In related technologies, the speed of picking up and bonding RFID die bonding is the key to the equipment during the production of RFID die bonding. Existing die bonding components all use a module to drive the bonding head to move back and forth quickly between two positions: picking up the die and bonding the die, to complete the picking up and bonding of RFID die bonding and complete the production of related RFID die bonding.

[0004] Regarding the aforementioned technologies, single-head pick-and-place assembly components have only one die bonding head. It must reciprocate between picking up and bonding the die, thus making it impossible to simultaneously complete the die picking and bonding operations, which affects RFID die bonding production.

The fixed block rotates, thereby driving the adsorption device to rotate. A support plate is fixed to the fixed block, providing support for the installation of the adsorption components. A sliding plate drives a limiting plate to slide elastically, providing support for the installation of the wafer suction nozzle. The wafer suction nozzle is connected to a vacuum intake rotary joint, thereby controlling the pickup of the wafer.

[0011] Optionally, the adsorption assembly further includes a suction nozzle sleeve rod, which is sleeved on the wafer suction nozzle and passes through the limiting plate and is rotatably connected to the limiting plate.

[0012] By adopting the above technical solution, the nozzle sleeve is installed on the limiting plate, and the nozzle sleeve provides support for the installation of the wafer nozzle, thereby enabling the wafer nozzle to be installed on the limiting plate and move vertically along the worktable.

The fixing plate is fixed to the worktable, the sliding plate is provided with an abutment groove, the cam is located in the abutment groove and the cam is rotatably connected to the fixing plate, and the cam abuts against the side wall of the abutment groove.

[0014] By adopting the above technical solution, the fixed plate provides support for the installation of the sliding plate and also provides support for the installation of the cam. The abutment groove provides space for the placement of the cam.

[0026] Optionally, the adsorption device further includes a buffer spring, which is sleeved on the wafer suction nozzle. One end of the buffer spring is fixedly connected to the limiting plate, and the other end is fixedly connected to the wafer suction nozzle.

[0027] By adopting the above technical solution, a buffer spring is sleeved on the wafer pick-up nozzle. When the wafer pick-up nozzle moves excessively downward, it retracts into the nozzle sleeve, and the buffer spring is compressed. After the pick-up operation is completed, the buffer spring returns to its original length, thereby returning the wafer pick-up nozzle to its initial position.

[0028] Optionally, the adsorption device further includes a sleeve buffer spring, which is sleeved on the wafer suction nozzle. One end of the sleeve buffer spring is fixedly connected to the limiting plate, and the other end is fixedly connected to the wafer suction nozzle.

[0061] The implementation principle of a six-position rotary chip picking and bonding device in this application embodiment is as follows: the first motor 21 drives the fixed block 24 to rotate, thereby driving the adsorption device 3 to rotate.

[0062] When the wafer is rotated to the wafer position, the second click drives the cam 433 to rotate, which in turn drives the sliding plate 431 to slide. At this time, the contact block 434 contacts the contact wheel 326, causing the limiting plate 323 to move downward, so that the wafer suction nozzle 325 can pick up the wafer. When the wafer suction nozzle 325 moves too far downward, the buffer spring 324 works to protect the wafer suction nozzle 325. When the contact block 434 is no longer in contact with the contact wheel 326, the limiting plate 323 returns to its original position.

[0063] Subsequently, the support plate 31 rotates to the detection component 44, and the camera 444 determines the position of the wafer. Then, for unqualified wafers, correction is performed. The correction motor 331 drives the micro guide sleeve 321 to rotate through the cooperation of the support wheel 332 and the correction synchronous wheel 333, which in turn drives the wafer suction nozzle 325 to rotate, and performs the correction operation on the wafer.

[0064] The wafer is then released in the feeding zone to prepare for the next wafer pick-up.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
