Therefore, research and innovation in its technology has always been the focus of industry attention.

[0003] Currently, most common firmware burning and testing equipment for integrated circuit packaging uses fixed-specification fixtures to fix integrated circuit chips in terms of mechanical structure and technical principles. During the burning and testing process, the programmer is connected to the chip through a specific electrical connection module to realize the transmission of firmware programs. As for the heat and harmful gases generated during the operation of the equipment, they mostly rely on simple ventilation holes or small fans for heat dissipation and gas exhaust. These traditional mechanical structures and technical solutions meet the basic burning and testing needs to a certain extent.

[0004] However, existing firmware programming and testing equipment for integrated circuit packaging has obvious drawbacks. Due to its fixed fixture specifications, it is difficult to adapt to integrated circuit chips of different sizes and shapes. When faced with diverse chip products, operators need to frequently change fixtures or use manual auxiliary fixing methods, which makes the fixing operation cumbersome, not only consuming a lot of time and labor costs, but also resulting in unstable fixing, which seriously affects production efficiency and product quality. Therefore, a firmware programming and testing equipment for integrated circuit packaging is proposed to solve the above problems. Summary of the Invention

[0013] As a further description of the above technical solution:

[0014] A base cabinet is fixedly connected to the bottom of the work box, and a controller is provided between the rotating bases. The bottom of the controller is fixedly connected to the bottom of the inner wall of the work box, and the rotating base is used to control the start and stop of the equipment and its parameters.

[0015] As a further description of the above technical solution:

[0016] The heat dissipation assembly includes two purification chambers. The outer walls of the purification chambers are fixedly connected to the inside of the side wall of the working chamber, and negative pressure fans are fixedly connected inside each purification chamber.

[0017] As a further description of the above technical solution:

[0018] Each purification box has a sliding groove inside, and a filter plate is slidably connected to the inner wall of each sliding groove. Each filter plate is located on the side of the negative pressure fan. Each filter plate has a handle fixedly connected to the top and a symmetrical locking block fixedly connected to the bottom.

[0019] As a further description of the above technical solution:

[0035] The fixing assembly includes a rotating base 4 made of aluminum alloy. The bottom of the rotating base 4 is rotatably connected to the inside of the work box 1 via bearings. A motor is installed inside the rotating base 4 to drive its rotation, facilitating the placement of integrated circuit modules in each receiving slot 6. Multiple receiving slots 6, formed by machining, are formed on the top of the rotating base 4 for placing integrated circuit modules. The receiving slots 6 are arranged in a circumferential shape. A programming interface 15 is fixedly connected to one side of the inner wall of each receiving slot 6. The programming interface 15 is made of metal contacts and insulating material, used for connecting to the plug of the integrated circuit module to achieve data transmission and power supply for firmware programming. A fixing box 7, made of stainless steel, is fixedly connected inside each receiving slot 6 for... The main rocker arm 9, guide rail 12, and other components are installed and fixed, providing a stable mounting base for these components. The bottom of the mounting box 7 is rotatably connected to the main rocker arm 9, which is made of alloy steel and rotates under the drive of the power assembly, thus moving the auxiliary rocker arm 10. The bottom of each main rocker arm 9 is equipped with a power assembly, and auxiliary rocker arms 10 are rotatably connected to both ends of the main rocker arm 9. The auxiliary rocker arms 10 are made of the same material as the main rocker arm 9 and are used to convert the rotation of the main rocker arm 9 into the linear motion of the sliding plate 11. Symmetrical guide rails 12, made of stainless steel, are fixedly connected to the bottom of the inner wall of the mounting box 7. The guide rails 12 provide guidance for the sliding of the sliding plate 11, ensuring that the sliding plate 11 can move stably within the mounting box 7. The top left of the guide rail 12... Sliding plates 11 are slidably connected to both sides. One end of each auxiliary rocker arm 10 is rotatably connected to the top center of the sliding plate 11 via a pin, thereby enabling the auxiliary rocker arm 10 to drive the sliding plate 11 to move. A clamping assembly is provided above each sliding plate 11 for clamping the integrated circuit module. The power assembly includes a drive motor 8, which is a device that converts electrical energy into mechanical energy. A servo motor is selected, providing high precision and stable power output. The top of the drive motor 8 is fixedly connected to the bottom of the outer wall of the fixed box 7, and the outer wall of the drive motor 8 is fixedly connected to the inside of the rotating base 4. The output end of the drive motor 8 is fixedly connected to the bottom center of the main rocker arm 9 via a coupling, providing power for the rotation of the main rocker arm 9. The clamping assembly includes a clamping plate 14. Plate 14 is made of aluminum alloy and its outer wall is covered with rubber pads for clamping integrated circuit modules. Plate 14 is located at the top of the fixed box 7. Connecting posts 13 are fixedly connected to the left and right sides of the bottom of plate 14. The bottom of each connecting post 13 is fixedly connected to the top of the sliding plate 11, which transmits the displacement of the sliding plate 11 to plate 14, enabling the movement of plate 14. A base cabinet 2 is fixedly connected to the bottom of the work box 1.

A controller 3 is installed between the rotating bases 4. The controller 3 consists of a metal shell and internal electronic components. The bottom of the controller 3 is fixedly connected to the bottom of the inner wall of the work box 1 by bolts. The rotating bases 4 are used to control the start / stop and parameters of the equipment.To facilitate staff operation of the equipment for firmware flashing and testing;

[0036] Referring to Figures 4 and 5, the heat dissipation assembly includes two purification chambers 5. In the firmware burning and testing equipment for integrated circuit packaging, the heat dissipation assembly plays a crucial role in heat dissipation and air purification. The purification chambers 5 are made of stainless steel, possessing good corrosion resistance and strength. The outer walls of the purification chambers 5 are fixedly connected to the inside of the side wall of the work chamber 1 via bolts, accommodating components such as the negative pressure fan 18 and filter plate 16, providing space for heat dissipation and air purification. Negative pressure fans 18 are fixedly connected inside each purification chamber 5. The negative pressure fan 18 is a device that generates negative pressure by rotating fan blades driven by a motor. It consists of a motor, fan blades, and a frame. The motor uses copper coils and silicon steel sheets, efficiently converting electrical energy into mechanical energy. The fan blades are made of plastic, offering lightweight and high airflow. Features: The frame is made of metal to fix the motor and fan blades, ensuring stable operation. When the negative pressure fan 18 is working, the high-speed rotation of the fan blades creates negative pressure inside the purification chamber 5, drawing hot air and harmful gases from inside the working chamber 1 into the purification chamber 5, achieving air flow and heat discharge. Each purification chamber 5 has a sliding groove 19, formed by machining on the inner wall, to guide the filter plates 16. Filter plates 16 are slidably connected to the inner wall of each groove 19. The filter plates 16 consist of multiple layers of filter material, including activated carbon filters and HEPA filters, effectively adsorbing and filtering harmful substances in the air. The filter plates 16 filter smoke and harmful gases drawn into the purification chamber 5, ensuring efficient airflow and heat discharge. For air purification, the filter plates 16 are all located on the side of the negative pressure fan 18. This layout allows the air to be purified by passing through the filter plates 16 before passing through the negative pressure fan 18. Each filter plate 16 has a handle 17 fixedly connected to its top. The handle 17 is made of plastic, allowing operators to pull or push the filter plate 16 for installation and removal. Each filter plate 16 has symmetrical locking blocks 24 fixedly connected to its bottom. The locking blocks 24 are made of metal and cooperate with the locking boxes 20 to secure the filter plate 16. Each filter plate 16 also has symmetrical locking boxes 20 at its bottom. The locking boxes 20 are made of stainless steel, offering high strength and wear resistance, and are used to install the locking ball 23, the limiting plate 22, and the limiting spring. Components such as spring 21 provide structural support for locking the filter plate 16. The outer wall of the locking box 20 is fixedly connected to the inside of the purification box 5. The locking box 20 has symmetrical locking balls 23 slidably connected inside. The side walls of the locking balls 23 are fixedly connected to limit the movement range of the locking balls 23 and prevent them from falling out of the locking box 20. Limiting springs 21 are provided on the side of the limiting plate 22. The limiting springs 21 are made of spring steel and have good elasticity. The function of the limiting springs 21 is to push the locking balls 23 into the locking block 24 when the filter plate 16 is installed in place, so as to lock the filter plate 16. One end of the limiting springs 21 is fixedly connected to the side wall of the limiting plate 22, and the other end of the limiting springs 21 is fixedly connected to the inside of the locking box 20.

[0037] Working principle: When using the firmware burning and testing equipment for integrated circuit packaging, the operator first places the integrated circuit module on top of the fixing box 7 inside the receiving slot 6. Then, the drive motor 8 drives the main rocker arm 9 to start rotating. The rotation of the main rocker arm 9 causes the auxiliary rocker arms 10 at both ends to swing. The swing of the auxiliary rocker arms 10 causes the sliding plates 11 on both sides to slide towards the center under the limit of the guide rail 12. The displacement of the guide rail 12 causes the clamping plate 14 to move towards the center through the connecting column 13 at its top until the side wall of the clamping plate 14 contacts the side wall of the integrated circuit module, thus completing the fixation of the integrated circuit module and achieving the effect of quickly fixing integrated circuit modules of different sizes.

[0038] Then, the device at the bottom of the rotating base 4 drives the rotating base 4 to rotate. The staff put the integrated circuit modules into the receiving slot 6 one by one. After all the integrated circuit modules are fixed, the staff connects the plug of the integrated circuit module to the burning interface 15 inside the receiving slot 6. Then, the staff performs firmware burning operation on the integrated circuit through the rotating base 4. During the burning operation, the integrated circuit module will generate heat and produce smoke and harmful gases. At this time, the negative pressure fan 18 inside the purification box 5 on one side of the work box 1 starts to work to generate negative pressure, which draws the hot air and harmful gases inside the work box 1 into the work box 1. Then, under the filtration of the filter plate 16, the hot air and the purified air are discharged from the purification box 5.

[0039] When the filter plate 16 needs to be replaced, the operator first pulls the handle 17 upwards. The handle 17 causes the filter plate 16 to slide upwards along the inner wall of the slide groove 19. The displacement of the filter plate 16 causes the two locking blocks 24 at its bottom to also move upwards. When the locking blocks 24 move, their outer walls press against the locking balls 23, causing the limiting plate 22 and the locking balls 23 to retract into the locking box 20. The limiting spring 21 is compressed. When the locking blocks 24 are completely disengaged from the locking box 20, the operator can remove the filter plate 16 and then insert the new filter plate 16 into the slide groove 19. At this time, the locking blocks 24 re-enter the locking box 20, and the limiting spring 21 pushes the locking balls 23 to engage in the recess on the outer wall of the locking blocks 24, thus completing the limiting of the filter plate 16. This achieves the effect of quickly replacing the filter plate 16 and ensuring the stable operation of the equipment.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
