[0002] A programmer, also known as a microcontroller, is a tool used to write data to programmable integrated circuits. Programmers are primarily used for programming chips such as microcontrollers and memory chips. They mainly modify the programs stored in read-only memory (ROM). Programmers are typically connected to a computer and used in conjunction with programming software. As one of the steps in chip manufacturing, programming requires precise control of the programming points; therefore, the chip placement accuracy is critical. Current chip programming processes can be performed manually or using programming devices. However, current chip programming devices are relatively complex and involve many steps, still requiring more manpower and resulting in lower efficiency. Summary of the Invention

[0009] The corner mounting plate further includes a locking part, a connecting part, and a mounting part arranged perpendicularly to each other. One side of the connecting part is connected to the locking part, and the lower part of the connecting part is connected to the mounting part. The locking part passes through the mounting plate and contacts one side surface of the first belt, and is locked and fixed with a toothed block arranged 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 part is arranged parallel to the mounting plate, and a groove for the slide rail to be embedded is opened on the side surface of the connecting part near the mounting plate. A through hole is opened on the mounting part, and the suction rod passes through the through hole and is installed and connected to the mounting part.

[0010] A motor bracket is installed on the lower part of the mounting plate. Several second motors corresponding to the suction rod are set on the motor bracket. A second drive wheel is connected to the rotation shaft of each second motor. A second driven wheel corresponding to the second drive wheel is fitted on the lower part of the suction rod. The second drive wheel and the second driven wheel are connected by a second belt drive.

[0011] It also has a limiting bracket, which is fixedly installed on the lower part of the front side of the mounting plate. The plurality of suction rods pass through this limiting bracket respectively. The suction rods are connected to the upper plate of the limiting bracket by an active spline. The suction rods are connected to the mounting part of the corner mounting plate by a driven spline. Both the active 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. The suction rods have grooves for the balls to be embedded in. One side of the ball is embedded in the inner wall of the cylindrical shell, and the other side is embedded in the groove of the suction rod.

[0012] The programming mechanism further includes a support plate, a base plate, several pressure plates, several programming sockets, and several cylinders corresponding to the pressure plates.

[0015] The following are further improvements to the above technical solution:

[0016] 1. In the above scheme, the four first motors are arranged in two staggered rows.

[0017] 2. In the above scheme, a Y-axis anti-collision block is installed at each end of the Y-axis lead screw.

[0018] 3. In the above scheme, a baffle plate is also provided above the active spline.

[0019] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0020] 1. This invention relates to a multi-station IC chip automatic programming equipment, which automates the entire chip programming process, including chip loading, programming, and unloading, with high precision and cyclic operation, improving the accuracy, efficiency, and automation of chip programming. Furthermore, the Y-axis drive mechanism has a first sensor at each end of the Y-axis lead screw, and the X-axis drive mechanism has a first baffle corresponding to the first sensor on its lower surface of the X-axis mounting plate. The X-axis drive mechanism also has a second sensor at each end of the X-axis mounting plate, and the suction mechanism has a second baffle corresponding to the second sensor on its lower surface. These sensors limit the movement of the suction mechanism on the X-axis and the X-axis drive mechanism on the Y-axis, preventing them from escaping the worktable and causing injury to personnel. Simultaneously, data can be fed back to the control center to determine the work origin in the X and Y axes, thus ensuring the accuracy of loading and unloading, and further guaranteeing the chip programming accuracy.

[0021] 2. The multi-station IC chip automatic programming equipment of the present invention further includes a suction mechanism comprising a mounting plate fixed to a second connecting block, a plurality of first motors, and a plurality of suction rods. The plurality of first motors are respectively mounted on a motor fixing plate, which is mounted on the upper rear surface of the mounting plate. The output shafts of the first motors pass through the motor fixing plate, and a first drive wheel is mounted at the end of each output shaft. A first driven wheel is mounted below each first drive wheel. A first belt connects the first drive wheel and the first driven wheel. The plurality of suction rods are respectively fixed to the first belt via a corner mounting plate. Using motor-driven suction rods replaces the use of cylinders to drive the suction rods. Firstly, this avoids the situation where excessive force causes the chip to fly away or be damaged during cylinder driving. Secondly, motor driving can stop at any position with high precision. Furthermore, the motor speed can be reduced when the end of the suction rod approaches the programming socket, ensuring the stability of chip picking and placing. In addition, one motor drives one suction rod, allowing for accurate adjustment of the position of each suction rod, ensuring the precision of the chip picked up by the suction rod. Thirdly, the corner mounting plate... The system further includes a locking part, a connecting part, and a mounting part arranged perpendicularly to each other. One side of the connecting part is connected to the locking part, and the lower part of the connecting part is connected to the mounting part. The locking part passes through the mounting plate and contacts one side surface of the first belt, and is locked and fixed to a toothed block located on the other side of the first belt. A slide rail corresponding to the corner mounting plate is mounted on the front surface of the mounting plate. The connecting part is arranged parallel to the mounting plate, and a groove for the slide rail to be inserted is opened on the side surface of the connecting part closest to the mounting plate. A through hole is opened on the mounting part, and the suction rod passes through the through hole and... The mounting section is connected to the toothed block, which corresponds to the toothed structure of the first belt. This tightly fixes the corner mounting plate to the first belt, effectively preventing relative sliding between the corner mounting plate and the first belt. This ensures the accuracy of the suction rod fixed on the corner mounting plate, thereby ensuring the accuracy of chip picking. In addition, the sliding groove on the connecting part and the slide rail on the mounting plate play a good limiting and guiding role for the corner mounting plate, thereby ensuring the vertical movement of the suction rod and ensuring the positional accuracy of the suction rod. This further ensures the accuracy of chip placement and programming.

[0022] 3. The multi-station IC chip automatic programming device of the present invention has a motor bracket mounted on the lower part of its mounting plate. Several second motors corresponding to the suction rods are mounted on this motor bracket. A second drive wheel is connected to the rotation shaft of each second motor. A second driven wheel corresponding to the second drive wheel is fitted onto the lower part of each suction rod. The second drive wheel and the second driven wheel are connected by a second belt drive. The second motors provide the suction rods with movement in the U-axis direction, i.e., rotational movement, which allows for fine-tuning of the chip rotation, further improving the chip positioning accuracy and ensuring programming accuracy. Secondly, it also has a limiting bracket, which is fixedly mounted on the lower part of the front side of the mounting plate. The suction rods pass through this limiting bracket. The suction rods are connected to the upper plate of the limiting bracket via an active spline, and the suction rods are connected to the mounting part of the corner mounting plate via a driven spline. Both the active and driven splines include a cylindrical shell and at least two rows of balls vertically arranged on the inner wall of the cylindrical shell. The suction rod has grooves for ball bearings to be embedded in. One side of the ball bearing is embedded in the inner wall of the cylindrical outer shell, and the other side is embedded in the groove of the suction rod. Through the setting of the active spline, the rotation of the second motor is transmitted to the second driven wheel, and then to the suction rod through the active spline, realizing the rotational movement of the suction rod. In addition, the setting of the driven spline, together with the active spline, forms two support points for the suction rod, ensuring the structural stability of the suction rod and thus ensuring the working accuracy of the suction rod. Furthermore, it also has a calibration mechanism, which further includes an upper camera and a lower camera. The upper camera is mounted on the suction mechanism, and the lower camera is mounted on the substrate and is positioned opposite to the upper camera. The setting of the calibration mechanism can calibrate the position of the chip in the X / Y axis and circumferential direction when the chip to be burned is small or the pins are too dense. The chip position is corrected by the X / Y axis drive mechanism and the rotation drive of the second motor, ensuring the accuracy of the chip position placed in the burning socket, thereby realizing high-precision burning of precision chips.

[0023] 4. The multi-station IC chip automatic programming equipment of the present invention has an X-axis anti-collision device installed on the surface of the X-axis nut away from the X-axis motor. The number of the plurality of first motors is four, arranged in two staggered rows. The staggered arrangement of the motors in two rows can save installation space and 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 requirements. Secondly, there is a baffle above the active spline. The baffle limits the spline and prevents 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 capture the metal parts, i.e., the chip pins, more clearly, thereby ensuring the calibration accuracy of the chip. Attached Figure Description

[0064] When using the aforementioned multi-station IC chip automatic programming equipment, the entire process of chip loading, programming, and unloading is fully automated, with high precision and cyclic operation, improving the accuracy, efficiency, and automation of chip programming. Secondly, through sensor settings, it can limit the movement of the suction mechanism on the X-axis and the X-axis drive mechanism in the Y-axis direction, preventing them from rushing off the operating table and causing injury to personnel. Simultaneously, it can feed data back to the control center to determine the operating origin in the X and Y axes, thus ensuring the accuracy of loading and unloading, further guaranteeing the chip programming accuracy. Thirdly, it uses a motor-driven suction rod instead of a cylinder to drive the suction rod, which avoids the problems associated with cylinder-driven systems. Excessive force can cause the chip to fly away or be damaged. The motor drive can stop at any position with high precision, and the motor speed can be reduced when the end of the suction rod approaches the programming socket, ensuring stability in chip picking and placing. Furthermore, one motor drives one suction rod, allowing precise adjustment of the position of each rod to ensure accurate chip placement. Additionally, the toothed block design corresponds to the toothed structure of the first belt, tightly fixing the corner mounting plate to the first belt, effectively preventing relative slippage between the corner mounting plate and the first belt, ensuring the precision of the suction rod fixed to the corner mounting plate, and thus ensuring accurate chip picking. Moreover, the sliding groove on the connecting part and the slide rail on the mounting plate provide good support for the corner mounting plate. The limiting and guiding function ensures the vertical movement of the suction rod, guaranteeing its positional accuracy and further ensuring the placement and programming accuracy of the chip. Secondly, the second motor provides the suction rod with movement along the U-axis, i.e., rotational motion, allowing for fine-tuning of the chip's rotation, further improving chip positioning accuracy and ensuring programming accuracy. Thirdly, the active spline transmits the rotational motion of the second motor to the second driven wheel, which in turn transmits it to the suction rod via the active spline, realizing the suction rod's rotational movement. Furthermore, the driven spline, together with the active spline, forms two support points for the suction rod, ensuring structural stability and thus guaranteeing its operational accuracy. Finally, the calibration mechanism... When programming chips that are small or have densely packed pins, the chip's position in the X / Y axes and circumferential direction can be calibrated. The chip position is corrected by the rotation drive of the X / Y axis drive mechanism and the second motor, ensuring the accuracy of the chip's position in the programming socket, thus achieving high-precision programming of precision chips. Furthermore, the staggered arrangement of the motors in two rows saves installation space and solves the problem of the motor's width exceeding the distance between the two suction rods, ensuring that the distance between the two suction rods is within the processing requirements. Additionally, the baffle design limits the spline, preventing it from popping out. Finally, the red light source ensures clearer imaging of the metal parts, i.e., the chip pins, thus guaranteeing the calibration accuracy of the chip.
