At the same time, data can be fed back to the control center to determine the operation origin in the X-axis and Y-axis directions, thereby ensuring the precision of loading and unloading and further ensuring the chip programming precision.

[0022] 2. The high-efficiency programming device for a chip according to the present invention, wherein the chip suction mechanism further includes a mounting plate fixedly installed with a second connecting block, a plurality of first motors, and a plurality of suction rods. The plurality of first motors are respectively installed on a motor fixing plate, and this motor fixing plate is installed on the upper part of the rear surface of the mounting plate. The output shafts of the first motors respectively pass through the motor fixing plate, and the ends of the output shafts of the first motors are respectively installed with first driving wheels. A first driven wheel is respectively installed below each of the first driving wheels. A first belt is connected between the first driving wheel and the first driven wheel. The plurality of suction rods are respectively fixedly installed with the first belt through a corner mounting plate. By using a motor to drive the suction rod instead of a cylinder to drive the suction rod, first, the situation that the chip is catapulted or damaged due to excessive force in the cylinder drive can be avoided. Moreover, the motor drive can stop at any position with high precision, and the motor can be decelerated when the end of the suction rod approaches the programming seat to ensure the stability of chip picking and placing. In addition, one motor drives one suction rod, and the position of each suction rod can be accurately adjusted to ensure the accuracy of the position of the chip sucked by the suction rod. Second, the corner mounting plate further includes a locking portion, a connecting portion, and a mounting portion that are perpendicular to each other in pairs. One side of the connecting portion is connected to the locking portion, and the lower part of the connecting portion is connected to the mounting portion. The locking portion passes through the mounting plate and contacts one side surface of the first belt, and is locked and fixed with a toothed block provided on the other side of the first belt. A slide rail corresponding to the corner mounting plate is installed on the front surface of the mounting plate. The connecting portion is arranged parallel to the mounting plate, and a chute for the slide rail to be embedded is opened on one side surface of the connecting portion close to the mounting plate. A through hole is opened on the mounting portion, and the suction rod passes through the through hole and is installed and connected with the mounting portion. The setting of the toothed block, corresponding to the toothed structure of the first belt, tightly fixes the corner mounting plate and the first belt, effectively preventing relative sliding between the corner mounting plate and the first belt, ensuring the accuracy of the suction rod fixed on the corner mounting plate, and thus ensuring the suction accuracy of the chip. In addition, the setting of the chute on the connecting portion and the slide rail on the mounting plate plays a good limiting and guiding role for the corner mounting plate, thereby ensuring the movement of the suction rod in the vertical direction, ensuring the position accuracy of the suction rod, and further ensuring the placement accuracy and programming accuracy of the chip.

[0023] 3. The high-efficiency chip programming device of the present invention has a motor bracket installed at the lower part of the mounting plate. A number of second motors corresponding to the suction rods are provided on this motor bracket. A second driving wheel is respectively connected to the rotating shaft of each second motor. A second driven wheel corresponding to the second driving wheel is sleeved on the lower part of the suction rod. The second driving wheel and the second driven wheel are connected by a second belt. The setting of the second motor provides the movement of the suction rod in the U-axis direction, that is, rotational movement, which can perform rotational fine-tuning on the chip, further improving the positioning accuracy of the chip, thereby ensuring the programming accuracy. Secondly, it also has a limit bracket, which is fixedly installed at the lower part of the front side of the mounting plate. The several suction rods respectively pass through this limit bracket. The suction rod is connected to the upper plate of the limit bracket by a driving spline, and the suction rod is connected to the mounting part of the corner mounting plate by a driven spline. Both the driving spline and the driven spline include a cylindrical shell and at least two rows of balls vertically arranged on the inner wall of the cylindrical shell. Grooves for the balls to be embedded are opened on the suction rod. One side of the balls is embedded in the inner wall of the cylindrical shell, and the other side is embedded in the groove of the suction rod. Through the setting of the driving spline, the rotational movement of the second motor is transmitted to the second driven wheel and then to the suction rod through the driving spline, realizing the rotational movement of the suction rod. In addition, the setting of the driven spline forms two support points for the suction rod with the driving spline, ensuring the structural stability of the suction rod, thereby ensuring the operation accuracy of the suction rod. Thirdly, it also has a calibration mechanism, which further includes an upper camera and a lower camera. The upper camera is installed on the suction mechanism, and the lower camera is installed on the substrate and is arranged face to face with the upper camera. The setting of the calibration mechanism can calibrate the position of the chip in the X / Y axes and the circumferential direction when the programmed chip is small or the pins are too dense, and correct the chip position through the X / Y axis driving mechanism and the rotational driving of the second motor, ensuring the accuracy of the chip position placed in the programming seat, thereby realizing the high-precision programming of precision chips.

[0024] 4. In the high-efficiency chip programming device of the present invention, an X-axis anti-collision is installed on the surface of the X-axis nut away from the X-axis motor. The number of the several first motors is 4, which are arranged in two rows staggered. The motors are arranged in two rows staggered, which can not only save the installation space but also solve the problem that the width of the motor itself is greater than the distance between the two suction rods, ensuring that the distance between the two suction rods is within the processing requirement range. Secondly, there is also a retaining piece above the driving spline. The setting of this retaining piece limits the spline to prevent the spline from popping out. Thirdly, the light source of the lower camera is a red light source. The setting of the red light source makes the camera take clearer pictures of the metal parts, that is, the chip pins, thereby ensuring the calibration accuracy of the chip.

[0065] When the above-mentioned efficient chip programming device is adopted, it realizes the full-automatic operation of chip loading, programming, and unloading during the chip programming process, with high precision, recyclable operation, and improved accuracy, efficiency, and automation of chip programming. Secondly, through the setting of sensors, it can limit the movement of the chip suction mechanism moving in the X direction and the X-axis driving mechanism moving in the Y-axis direction, preventing them from rushing out of the operating table and causing harm to personnel. At the same time, it can feedback data to the control center to determine the operation origin in the X-axis and Y-axis directions, thus ensuring the accuracy of loading and unloading and further ensuring the programming accuracy of the chip. Thirdly, it uses a motor to drive the suction rod instead of a cylinder to drive the suction rod. Firstly, it can avoid the situation of the chip being catapulted or damaged due to excessive force in cylinder driving. Moreover, the motor drive can stop at any position with high precision, and the motor can be decelerated when the end of the suction rod approaches the programming seat to ensure the stability of chip picking and placing. In addition, one motor drives one suction rod, which can accurately adjust the position of each suction rod to ensure the accuracy of the position of the chip sucked by the suction rod. Fourthly, the setting of the toothed block, corresponding to the toothed structure of the first belt, tightly fixes the corner mounting plate to the first belt, effectively preventing relative sliding between the corner mounting plate and the first belt, ensuring the accuracy of the suction rod fixed to the corner mounting plate, and thus ensuring the suction accuracy of the chip. In addition, the setting of the chute on the connecting part and the slide rail on the mounting plate plays a good role in limiting and guiding the corner mounting plate, thus ensuring the movement of the suction rod in the vertical direction, ensuring the position accuracy of the suction rod, and further ensuring the placement accuracy and programming accuracy of the chip. Fifthly, the setting of the second motor provides the movement of the suction rod in the U-axis direction, that is, rotational movement, which can perform rotational fine-tuning on the chip to further improve the positioning accuracy of the chip and thus ensure the programming accuracy. Sixthly, through the setting of the driving spline, the rotational movement of the second motor is transmitted to the second driven wheel and then transmitted to the suction rod through the driving spline to realize the rotational movement of the suction rod. In addition, the setting of the driven spline forms two support points for the suction rod with the driving spline, ensuring the structural stability of the suction rod and thus ensuring the operation accuracy of the suction rod. Seventhly, the setting of its calibration mechanism can calibrate the position of the chip in the X / Y axis and circumferential directions when the programmed chip is small or the pins are too dense, and correct the chip position through the rotational drive of the X / Y axis driving mechanism and the second motor, ensuring the accuracy of the chip position placed in the programming seat, and thus realizing the high-precision programming of precision chips. Eighthly, the motors are arranged in two rows staggered, which can not only save installation space but also solve the problem that the width of the motor itself is greater than the distance between the two suction rods, ensuring that the distance between the two suction rods is within the processing requirement range. Ninthly, the setting of the retaining piece limits the spline to prevent the spline from popping out. Tenthly, the setting of the red light source makes the camera take clearer pictures of the metal parts, that is, the chip pins, thus ensuring the calibration accuracy of the chip.
