[0018] See attached document Figure 1-5A crucible lid flipping and cleaning device includes a conveyor line 10, a flipping section 70, and a cleaning section 80. The flipping section 70 is installed at the input end of the conveyor line 10, and the cleaning section 80 is installed at the output end of the conveyor line 10. The flipping section 70 includes a rotary motor 701, a rotary shaft 702, a rotary rectangular frame 703, clamping plates 704, and cross braces 706. The two ends of the rotary shaft 702 are rotatably mounted on the conveyor line 10. The rotary rectangular frame 703 is installed in the middle of the rotary shaft 702. Two cross braces 706 are installed at the upper end of the conveyor line 10. A clearance groove 707 is formed between the two cross braces 706 to allow the rotary rectangular frame 703 to rotate. Two clamping plates 704 are installed at one end of the rotary rectangular frame 703, and a slot 708 for the crucible lid to enter is left at that end. A counterweight 709 is installed at the other end of the rotary rectangular frame 703. A rotary motor 701 is installed below the conveyor line 10, driving either end of a rotating shaft 702. The cleaning section 80 includes a roller brush 801, a rubber roller 802, a drive motor 803, and a rectangular frame 804. A rectangular frame 804 is installed above the conveyor line 10. Multiple sets of rubber rollers 802 and roller brushes 801 are alternately installed within the rectangular frame 804. The ends of the rubber rollers 802 and roller brushes 801 rotate on the side plates of the rectangular frame 804. A drive motor 803 is installed on the outer side of one side plate of the rectangular frame 804. The drive motor 803 drives one end of the multiple sets of rubber rollers 802 and roller brushes 801 via multiple pulleys and a synchronous belt. A gap is left between the multiple sets of rubber rollers 802 and roller brushes 801 and the conveyor rollers of the conveyor line 10 for the crucible lid to pass through. The rotary motor drives the rotating shaft via a sprocket and chain, which is existing technology; this invention is not limited to this drive structure.

[0019] The clamping plates 704 are designed as two plates, one above the other. The outer sides of each clamping plate 704 are fixed to the rotating rectangular frame 703 via clamping cylinders 710. The front telescopic end of the clamping cylinder 710 is connected to the middle of the back side of the clamping plate 704, and the rear end of the clamping cylinder 710 is mounted on the upper or lower side of the rotating rectangular frame 703 via a U-shaped plate 7041. The clamping plates 704 can move up and down within a rectangular groove running vertically through the center of the rotating rectangular frame 703. The slot 708 for the crucible lid to enter is connected to the rectangular groove. The clamping cylinders control the effective clamping action of the clamping plates to meet the clamping requirements.

[0020] Conveying rollers 101 are installed between the outer sides of the two cross braces 706 and the two side plates of the conveyor line 10. Since the flipping action of the flipping section requires clearance from the groove, the longer conveying rollers of the conveyor line are adjusted to short and narrow conveying rollers, saving space while still maintaining the original conveying drive function. The length of the conveying rollers can be adjusted according to actual needs; the main purpose is to convey the rectangular cover of the crucible without interfering with the operation of the flipping section.

[0021] Guide rods 7042 are installed on the back side of the clamping plate 704 near both sides, and guide sleeves for guiding the guide rods 7042 are installed on the U-shaped plate 7041. The guide rod 7042 guide sleeve design ensures stable and safe clamping of the clamping plate. Polyurethane gaskets are also installed on the inner side of the clamping plate for protection.

[0022] An inductive switch 711 is installed on the front and rear sides of the two cross braces 706. The design of the two inductive switches ensures that the flipping part can effectively monitor the entry and exit of the rectangular cover 100 of the crucible, and operate in an orderly manner.

[0023] The rectangular frame 804 of the cleaning section 80 is covered with a cover plate 805, and an inverted U-shaped cover 806 is also installed on the conveyor lines 10 on both sides of the cleaning section 80. A U-shaped groove 807 is designed below the cleaning section 80 and the two U-shaped covers, and the U-shaped groove is installed below the conveyor line 10. The cover plate, the inverted U-shaped cover, and the lower U-shaped groove are designed to prevent dust from overflowing. The dust eventually settles in the U-shaped groove and can be cleaned periodically. The length of the inverted U-shaped cover is designed to prevent dust from overflowing from both ends. The upper end of the inverted U-shaped cover can also be designed with an openable flip-top for easy observation and cleaning operations. The cover plate is designed to be flip-up for easy opening.

[0024] The groove 708 for the crucible lid to enter is designed with a cylindrical buffer positioning bracket 712 installed on the upper and lower layers of the opening. The upper end of the cylindrical buffer positioning bracket 712 is installed at the upper and lower positions of the opening through a connector, and the lower end of the cylindrical buffer positioning bracket 712 can be supported on the brackets 102 on both sides of the conveyor line 10.

[0025] In use, the robotic arm removes the rectangular lid 100 of the crucible from the rectangular groove of the crucible and places it on a designated conveyor line for cleaning. The rectangular lid 100, transported by the conveyor line, reaches the flipping section. A sensor switch detects the arrival signal of the rectangular lid 100, and the rotating rectangular frame of the flipping section is normally horizontal. The groove for the crucible lid is aligned with the conveyor path, ensuring that the rectangular lid 100 is transported along the conveyor rollers on both sides of the conveyor line into the groove for the crucible lid. At this time, the upper and lower clamping cylinders synchronously drive the upper and lower clamping plates to clamp the crucible lid. The rotary motor controls the rotating rectangular frame to rotate 180 degrees via the rotating shaft, causing the rectangular lid... With the inner side of the plate facing upwards, the upper and lower clamping cylinders control the clamping plates to release their grip. The rectangular cover plate is then conveyed to the cleaning section by the conveyor rollers of the conveyor line. When the induction switch detects that the rectangular cover plate has left the slot for the crucible cover to enter, the flipping part rotates in the opposite direction to reset. When the rectangular cover plate enters the cleaning section, the rubber rollers of the cleaning section and the conveyor rollers of the conveyor line clamp the rectangular cover plate and pull it forward, so that the rectangular cover plate passes smoothly between the roller brush and the conveyor rollers of the conveyor line. While passing through the roller brush, the inner side of the rectangular cover plate is cleaned. Under the action of multiple sets of rubber rollers and roller brushes, the inner side of the rectangular cover plate of the crucible is effectively cleaned. Then, the cleaned rectangular cover plate is sent to the next process through the conveyor line.
