Existing equipment typically performs cleaning and drying in two separate processes. Operating the crystal trays increases the number of processes and the work cycle. If these two processes are run continuously, the cleaning and drying processes interfere with each other. The drying process interferes with the final stage of cleaning, leading to incomplete cleaning. Furthermore, the incomplete cleaning in the preceding stages affects the wear and tear on the drying components. Further research and development are needed to solve these problems, meet cleaning requirements, improve work efficiency, and ensure the effectiveness of rinsing and drying so as not to affect the use of subsequent processes.

[0022] A rinsing and drying mechanism, such as Figure 1 As shown, the device includes a conveyor roller 1 for conveying crystal trays; a housing 2 is installed on the conveyor roller 1, and a rinsing assembly and a drying assembly are sequentially installed inside the housing 2 for rinsing and drying the crystal trays, respectively. A drive motor 6 for driving the conveyor roller 1 is installed on one side of the conveyor roller 1, and the output end of the drive motor 6 is connected to the conveyor roller 1. A lifting assembly for opening the housing door is installed at the front end of the housing 2. A baffle is installed between the rinsing assembly and the drying assembly. The baffle is installed inside the housing, and a channel for the crystal trays to pass through is provided on the baffle. The shape of the channel is similar to that of the crystal trays.

[0023] The rinsing assembly includes a rinsing bracket, which is fixed inside the housing 2 and positioned above the conveyor roller 1. Several rinsing nozzles 4 are mounted on the rinsing bracket. The rinsing nozzles 4 are equidistantly spaced, and their vertical surfaces are inclined. Preferably, four rinsing nozzles 4 are provided. Each rinsing nozzle 4 is connected to a water spray pipe, which passes through an external water pipe connected to the housing 2. A solenoid valve is mounted on the water pipe. The connection between the water spray pipe and the housing 2 is sealed.

[0024] The air-drying assembly includes an air-drying support frame, which is fixed inside the housing 2 and positioned above the conveyor roller conveyor 1. Several air-drying nozzles 5 are equidistantly arranged on the air-drying support frame, and their vertical surfaces are inclined. Preferably, four air-drying nozzles 5 are provided. The air-drying nozzles 5 are connected to a vacuum pipe, which passes through the housing 2 and connects to a vacuum generator. A solenoid valve is installed on the vacuum pipe. The connection between the vacuum pipe and the housing 2 is sealed.

[0025] A proximity switch 9 is provided at the end of housing 2 to detect when the crystal holder is in place.

[0026] The box 2 is installed on the conveyor roller 1.

[0027] The lifting assembly includes a lifting cylinder 3 and a lifting door 8; the lifting cylinder 3 is located on the front outer wall of the housing 2, and the front end of the cylinder rod of the lifting cylinder 3 is connected to the upper part of the lifting door 8 through a connector.

[0028] The front wall panel of the housing 2 is provided with a channel for the crystal tray to pass through, and the opening and closing is achieved by a lifting sliding door 8.

[0029] The rinsing and drying mechanism is mounted on the base 10 and can be fixed to the frame via the base 10.

[0030] The conveyor roller conveyor 1 includes a conveyor frame, on which two side frames are provided. Several transmission shafts 7 are provided between the supports of the two side frames. The several transmission shafts 7 are equidistant and their two ends are respectively located in the two side frames. The ends of the transmission shafts 7 on the same side are connected by gears and racks. One of the gears is connected to the drive shaft of the drive motor 6 to achieve drive.

[0031] The lifting cylinder 3 is mounted on the housing 2 via a cylinder mounting bracket, and a workpiece positioning sensor is mounted on the cylinder mounting bracket to detect when the crystal tray is in place.

[0032] Both the rinsing and drying components are equipped with sensors to detect the position of the workpiece and the crystal holder. Preferably, two sensors are installed in each component, and both are located inside the housing 2.

[0033] The rinsing and drying mechanism is also equipped with a PLC control system. The lifting cylinder 3, rinsing nozzle 4, drying nozzle 5, drive motor 6, proximity switch 9, solenoid valve, vacuum generator, and workpiece positioning sensor are all connected to the PLC control system. They are not limited to any specific model, as long as they can achieve their working functions.

[0034] In actual operation, the workpiece crystal tray (which can be an existing robotic arm or a gantry, or any existing equipment for transfer, without specific description or limitation) is moved to the conveyor roller 1 from the previous process. The drive motor 6 on the conveyor roller 1 starts working. The drive motor 6 is connected to a drive shaft and gears, which in turn drive the transmission shaft 7 to move as a whole, thereby moving the crystal tray forward. When the workpiece arrival sensor at the lifting cylinder 3 detects the crystal tray, the lifting cylinder 3 starts working. The cylinder rod of the lifting cylinder 3 retracts, thereby opening the lifting door 8. The front wall panel of the housing 2 is provided with a channel for the crystal tray to pass through, allowing the crystal tray to enter. In the rinsing assembly inside chamber 2, when the workpiece positioning sensor detects that the crystal tray has reached the cleaning position, it sends a feedback signal to the PLC control system. The PLC control system then sends a feedback signal to the rinsing nozzle 4 to activate, rinsing the crystal tray. While being rinsed, the crystal tray passes through a channel on the baffle and enters the drying assembly. When the workpiece positioning sensor detects that the crystal tray has reached the drying position, it sends a feedback signal to the PLC control system. The PLC control system then sends a feedback signal to the drying nozzle 5 to activate, drying the crystal tray. After drying, the crystal tray is conveyed via conveyor roller 1. When proximity switch 9 detects the crystal tray, the next process arrives to remove it, or the conveyor roller stops working. The contoured channels on the baffles prevent interference between components, and the overall enclosure 2, with its lifting door 8, reduces external interference from the rinsing assembly, minimizing wear and tear. Furthermore, the entire rinsing and drying process does not stop, shortening the work cycle and improving work efficiency.

[0035] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
