Abstract
Description
Technical Field
[0001] This utility model belongs to the field of microwave plasma cleaning machine technology, and more specifically, it relates to a material pushing mechanism for a microwave plasma cleaning machine. Background Technology
[0002] With the increasing integration of electronic circuits, the shrinking of chip feature sizes, and the research and application of new materials, the requirements for surface treatment and cleaning are becoming increasingly stringent. Plasma surface cleaning technology has become an important means to improve product reliability and yield, and is an indispensable step in the production process. In a vacuum chamber, high-energy, disordered plasma is generated under certain pressure using a radio frequency power supply. This plasma bombards the surface of the product being cleaned, achieving the cleaning purpose.
[0003] Plasma cleaning is a novel high-tech technology that utilizes plasma to clean electronic products that are difficult to clean using conventional methods, while also meeting the new process requirements of non-destructive cleaning and corrosion inhibition. Currently, plasma cleaning equipment is classified into three types based on excitation frequency: low-frequency, radio-frequency (medium-frequency), and microwave plasma cleaners. Among these, microwaves have the highest discharge frequency, the greatest gas ionization degree, extremely low self-bias voltage, low ion impact, minimal damage to devices, and do not produce ultraviolet radiation. Due to these advantages, microwave plasma is irreplaceable in certain processes.
[0004] The existing automatic feeding device of plasma cleaners has the following drawbacks: Before use, the plasma cleaner needs to be fed into the machine. Most plasma cleaners require the sealed door to be opened during feeding, and the material needs to be manually moved to the designated cleaning station. This makes the feeding process of the plasma cleaner complicated and labor-intensive, and requires improvement by the staff. Utility Model Content

[0023] Please see Figures 1 to 3 This utility model provides a technical solution: a feeding mechanism for a microwave plasma cleaner, including a mounting bracket 1, a material carrier 2 fixedly connected to the bottom of the mounting bracket 1, a cylinder frame 3 fixedly connected to the surface of the mounting bracket 1, a lifting cylinder 4 on the cylinder frame 3, a lifting block 5 fixedly connected to the piston rod of the lifting cylinder 4, a sliding assembly 6 between the lifting block 5 and the surface of the mounting bracket 1, the sliding assembly 6 including a slide rail 61 located on the surface of the mounting bracket 1, and a sliding block 62 fixedly connected to the bottom of the lifting block 5, the sliding block 62 being slidably connected to the slide rail 61. A rack 7 fixedly connected to the side wall of the lifting block 5, limiting blocks 8 fixedly connected to both ends of the rack 7, a driven gear 9 meshing with one side of the rack 7, a rotating shaft 10 fixedly connected to the center of the driven gear 9, a first bearing seat 11 rotatably connected to the bottom of the rotating shaft 10, the first bearing seat 11 being fixed to the surface of the mounting bracket 1, and a second bearing seat 12 rotatably connected to the end of the rotating shaft 10 away from the mounting bracket 1, the second bearing seat 12 being fixed to the surface of the mounting bracket 1 by a stabilizing bracket 13.
[0024] The rotating shaft 10 is also provided with a fixedly connected swing rod 14. An electric telescopic rod 15 is provided at the end of the swing rod 14, and a gripping clamping assembly 16 is provided at the end of the output shaft of the electric telescopic rod 15. The gripping clamping assembly 16 includes a telescopic plate 1601 located at the end of the output shaft of the electric telescopic rod 15, a first rotary clamping cylinder 1602 and a second rotary clamping cylinder 1603 located on the surface of the telescopic plate 1601. The first rotary clamping cylinder 1602 and the second rotary clamping cylinder 1603 are synchronously controlled and driven, and the gripper surfaces of the first rotary clamping cylinder 1602 and the second rotary clamping cylinder 1603 are provided with anti-slip pads 17.

[0025] The specific usage and function of this embodiment: The wafer products that need to be cleaned are placed on the carrier rack 2. Then, the lifting cylinder 4 drives the lifting block 5 and the rack 7 on its surface to move upward. Since the surface of the rack 7 is meshed with the driven gear 9 on one side, the driven gear 9 rotates counterclockwise, thereby driving the fixedly connected rotating shaft 10 to rotate. The swing rod 14 located on the rotating shaft 10 rotates together. After the swing rod 14 drives the gripping and clamping assembly 16 at the head to the designated surface of the carrier rack 2, the gripping position of the gripping and clamping assembly 16 is flexibly adjusted by the electric telescopic rod 15 according to the actual gripping requirements. The first and second rotary clamping cylinders 1602 and 1603 on the surface of the telescopic plate 1601 operate, adjusting the angle. Pneumatic grippers on both sides clamp the wafer tray on the surface of the carrier rack 2. Then, the lifting cylinder 4 retracts its piston rod, causing the rack 7 to move downwards, resulting in the clockwise rotation of the driven gear 9. This causes the swing rod 14, the gripping and clamping assembly 16, and the wafer tray to rotate upwards. After reaching the designated cleaning station, the first and second rotary clamping cylinders 1602 and 1603 release the pneumatic grippers, completing the feeding process at the cleaning station. The entire process is simple to operate and convenient to use, enabling rapid and stable transport of large batches of wafers. It boasts a high degree of automation, reduces manual handling, and significantly improves cleaning efficiency.
