[0002] In the chip manufacturing process, the programming step is a crucial step in writing programs or data into the chip. Traditional chip programming equipment typically uses a fixed material handling structure or a single-axis robot for picking and placing materials, which has the following technical drawbacks: a single-axis robot can only pick up and place one chip at a time, which cannot meet the high-efficiency requirements of batch programming; fixed fixtures are difficult to adapt to the variable distance requirements of chips of different sizes, which can easily lead to positioning errors; existing equipment lacks multi-station collaborative capabilities, and the feeding, programming, and unloading processes require manual intervention, resulting in low automation.

[0018] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] Reference Figures 1-6 As shown, this embodiment provides a chip programming device, including a machine base 1 and a programming fixture 2 mounted on the machine base 1. The machine base 1 is equipped with a three-axis gantry loading and unloading module 3. The three-axis gantry loading and unloading module 3 includes Y-axis slide rails 4 on both sides of the programming fixture 2, X-axis slide rails 5 mounted on the two Y-axis slide rails 4, and Z-axis slide rails 6 perpendicularly mounted on the X-axis slide rails 5. The Z-axis slide rail 6 is equipped with a variable-pitch pick-and-place module 7. The variable-pitch pick-and-place module 7 includes a lifting seat 8 mounted on the Z-axis slide rail 6, an X-axis linear variable-pitch module 9 mounted on the lifting seat 8, and two Y-axis linear variable-pitch modules 10 mounted on the X-axis linear variable-pitch module 9. The Y-axis linear variable-pitch module 10 is equipped with at least two picks 11.

[0021] In the chip programming placement device of this invention, the Y-axis and X-axis slide rails drive the entire variable-pitch pick-and-place module to move horizontally, precisely positioning it above the loading station, programming fixture, and unloading station. The Z-axis slide rail drives the variable-pitch pick-and-place module to rise and fall, completing the picking and placing actions. The X-axis linear variable-pitch module 9 and the Y-axis linear variable-pitch module 10 are used to adjust the relative distance between multiple pick-and-place devices. This constructs an automated execution mechanism capable of precise positioning in three-dimensional space and flexible adjustment of the gripping distance; the variable-pitch pick-and-place module adjusts the pick-and-place device spacing through the X-axis and Y-axis linear variable-pitch modules to adapt to chips of different sizes; the pick-and-place device (vacuum nozzle) completes chip gripping and release; it supports simultaneous pick-and-place of multiple chips, improving efficiency by more than 50%; the variable-pitch function is compatible with various chip specifications, reducing equipment changeover time and facilitating automated loading and unloading, eliminating manual operation; the three-axis linkage ensures positioning accuracy; the variable-pitch function lays the foundation for adapting to different products and improves the equipment's versatility.

[0022] Specifically, the X-axis linear variable pitch module 9 includes a transverse linear slide rail 12 located at the front end of the lifting base 8 and two transverse slide tables 13 located on the transverse linear slide rail 12. The Y-axis linear variable pitch module 10 is located on the transverse slide tables 13. In this embodiment, the X-axis variable pitch module is further defined as consisting of a transverse linear slide rail and two transverse slide tables. The two Y-axis variable pitch modules are respectively mounted on the two transverse slide tables. By driving the two transverse slide tables to move towards or away from each other on the transverse linear slide rail, the overall spacing adjustment of the two Y-axis variable pitch modules (and all the suction devices on them) in the X direction is realized; this is the first pitch change, used to adapt to the width change of the material tray in the X direction.

[0023] Specifically, the Y-axis linear variable pitch module 10 includes two material pick-up seats 15 respectively mounted on two transverse slides 13, a longitudinal guide rail 101 located inside the two material pick-up seats 15, and two longitudinal slides 102 mounted on the longitudinal guide rails 101. The suction device 11 is vertically mounted on the longitudinal slides 102. Two connecting blocks 103 are respectively connected to the two longitudinal slides 102 on the outer side of each material pick-up seat 15. A Y-axis variable pitch cylinder 16 is located on the outer side of each material pick-up seat 15. The connecting block 103 is provided with racks 104 respectively. The outer side of the material taking seat 15 is provided with intermediate gears 105 that mesh with the two racks 104. The piston rod of the Y-direction variable pitch cylinder 16 is connected to the connecting block 103. The material taking seat 15 is provided with receiving grooves through both sides for the two connecting blocks 103 to be inserted. The two connecting blocks 103 are provided with longitudinal sliding grooves. The racks 104 are located in the longitudinal sliding grooves, and the intermediate gears 105 are inserted into the longitudinal sliding grooves.

[0024] In this embodiment, the Y-axis linear variable pitch module 10 includes a pick-up base, a longitudinal guide rail, a longitudinal slide, a connecting block, a Y-axis variable pitch cylinder, a rack, and an intermediate gear. Its core is a gear-rack synchronous reverse mechanism. The Y-axis variable pitch cylinder pushes one of the connecting blocks to move, the rack on that connecting block drives the intermediate gear to rotate, and the intermediate gear then drives the rack on the other connecting block to move in the opposite direction. This causes the two connecting blocks to drive their respective longitudinal slides and the pick-up devices on them to move synchronously and in opposite directions on the pick-up base. This achieves precise and synchronous adjustment of the spacing between the two pick-up devices in the Y direction on a single pick-up base. It also achieves a second pitch change to adapt to the spacing of the chips in the Y direction. The synchronous reverse movement ensures that the centers of the two pick-up devices are always located on the centerline of the pick-up base, resulting in symmetrical movement, balanced force, and prevention of jamming, thus improving adjustment accuracy and stability. The design of the receiving groove and longitudinal slide makes the structure compact and protects the transmission components.

[0025] Specifically, each of the feeding seats 15 has three pickers 11, two of which are located on the longitudinal slides 102 of the longitudinal guide rail 101, and the third is located inside the feeding seat 15 and arranged between the two longitudinal slides 102. In this embodiment, the two movable pickers are used to pick up chips with standard spacing and can adapt to different sizes by varying the spacing. The fixed middle picker can be used to pick up chips of a specific size or to provide auxiliary support and balance. This layout increases the number of chips picked up at one time without increasing the complexity of the drive, further improving efficiency and enhancing the flexibility of the layout.

[0026] Specifically, the bottom of the suction device 11 is equipped with a vacuum nozzle 17 that connects to a negative pressure device. Vacuum suction is a non-contact, non-destructive material handling method, particularly suitable for precision electronic components. It has a simple structure, is easy to control, and allows for rapid gripping and release, which is beneficial for high-speed operations.

[0027] Specifically, the front end of the machine tool 1 is provided with a loading station 18 and a discharging station 19 on both sides, respectively. The loading station 18 and the discharging station 19 are located between the burning fixture 2 and the Y-axis slide rails 4 on both sides. In this embodiment, it is clear that the loading station and the discharging station are located on both sides of the front end of the machine tool, between the burning fixture and the Y-axis slide rails; the layout logic is clear and the process is smooth. The movement range of the three-axis module can efficiently cover these three core stations, avoiding unnecessary idle strokes and optimizing the equipment cycle time.

[0028] Specifically, the Y-axis slide rail 4 includes two parallel Y-axis guide rails and a first worm gear transmission assembly located at one end of the Y-axis guide rails. The Y-axis guide rails are provided with a Y-axis lead screw connected to the worm wheel of the first worm gear transmission assembly. A synchronous shaft 23 is connected between the worms of the two first worm gear transmission assemblies. A Y-axis drive motor for driving the worm of the first worm gear transmission assembly to rotate is provided on one side of the Y-axis slide rail 4. A Y-axis slide table 25 that is threadedly connected to the Y-axis lead screw is slidably provided on the Y-axis guide rails.

[0029] Furthermore, the X-axis slide rail 5 includes a gantry frame 26, an X-axis guide rail 27 mounted on the crossbeam of the gantry frame 26, and a second worm gear transmission assembly mounted on the X-axis guide rail 27. The X-axis guide rail 27 is provided with an X-axis lead screw connected to the worm wheel of the second worm gear transmission assembly. One side of the X-axis slide rail 5 is provided with an X-axis drive motor 29 that drives the worm of the second worm gear transmission assembly to rotate. An X-axis slide table 28 that is threadedly connected to the X-axis lead screw is slidably mounted on the X-axis guide rail 27. The bottom ends of both sides of the gantry frame 26 are connected to two Y-axis slide tables 25.

[0030] In this embodiment, the Y-axis and X-axis slide rails adopt a "worm gear + lead screw" drive method, and a synchronous shaft ensures the synchronous movement of the two Y-axis slide rails. The drive motor reduces speed and changes the transmission direction through the worm gear assembly, driving the lead screw to rotate, thereby driving the linear motion of the slide table. The synchronous shaft forcibly connects the worm gears on both sides to ensure absolute synchronization of movement. This provides a high-rigidity, high-precision drive solution capable of withstanding heavy loads on the gantry frame and solves the synchronization problem of dual Y-axis drive. The worm gear transmission has a self-locking function to prevent the gantry frame from sliding down when power is off, ensuring safety and reliability. The synchronous shaft design fundamentally eliminates the asynchrony error that may occur in dual-motor drive, ensuring that the X-axis slide rail is always perpendicular to the Y-axis guide rail, resulting in extremely high motion accuracy.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above embodiments only illustrate one or more implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
