Description

Technical Field

[0001] The utility model relates to the technical field of solar cell production, in particular to a graphite boat cleaning device. Background Art

[0002] As the most important fixture for coating, the graphite boat needs to be cleaned frequently due to its service life. The graphite boat is generally used for 4 days and the processing cycle is 1 day. The first step in the processing is to clean the graphite boat, which takes 14 hours.

[0003] The graphite boat cleaning equipment currently in widespread use includes the following cleaning process: pickling (7 hours) → spraying (0.5h) → water washing (2h) → air drying (25min). Considering the structural design and capacity calculation, the number of pickling tanks in the graphite boat cleaning equipment is 10, the number of spray tanks is 1, the number of water washing tanks is 9, and the number of air drying tanks is 1. Under normal circumstances, such a number of tank body composition structures can meet production needs. However, when the robot is abnormal or the graphite boat is cleaned centrally, it is easy for the pickling tank to wait for the spray tank to be empty, resulting in the graphite boat not being able to leave the boat, or the graphite boat in the water washing tank to wait for the air drying tank to be empty. If the pickling tank is over-pickled, it will affect the service life of the graphite boat and easily produce batch defects. And if you have to wait for the next tank to be empty, it will waste production capacity, resulting in the boat not being able to be loaded in time, and also waste production costs. Therefore, it is urgent to develop a graphite boat cleaning equipment to overcome the above problems. Utility Model Content

[0038] Example

[0039] The utility model will be further described below in conjunction with the accompanying drawings.

[0040] like Figures 1 to 7 As shown, a graphite boat cleaning device provided in this embodiment includes a box body 1, in which an upper temporary storage chamber and a lower cleaning chamber which are interconnected are arranged one above and one below the box body 1, a plurality of trough bodies 2 are arranged in parallel at the bottom of the lower cleaning chamber, a lower transverse movement assembly is installed on the inner wall of the lower cleaning chamber, the lower transverse movement assembly includes a vertically arranged lower track 3, a hook assembly moves on the lower track 3, the hook assembly is used to pick up the graphite boat, a plurality of temporary storage racks 4 are arranged in parallel in the upper temporary storage chamber, an upper transverse movement assembly is installed on the inner wall of the upper temporary storage chamber, the upper transverse movement assembly includes an upper track 5 which is equal to the number of the temporary storage racks 4, the upper track 5 is arranged vertically, and when the upper track 5 is docked with the lower track 3, the hook assembly moves from the lower track 3 to the upper track 5.

[0041] The working principle and beneficial effects of the above technical solution are:

[0042] The utility model discloses a graphite boat cleaning device. When the graphite boat is sent into the device for cleaning, a hook assembly picks up the graphite boat, and the hook assembly moves upward on a lower track 3, thereby lifting the graphite boat to a suitable position, and then the graphite boat is transported to the top of a target tank body 2 through a lower transverse moving assembly, and the hook assembly moves downward on the lower track 3, thereby placing the graphite boat in the target tank body 2, and then the lower transverse moving assembly retreats, thereby separating the hook assembly from the graphite boat, and then moving upward to separate from the tank body 2.

[0043] When taking the boat, it reaches the top of the target tank body 2 under the action of the lower transverse movement assembly, the hook assembly moves downward on the lower track 3 and contacts the position of the graphite boat, and then with the cooperation of the lower transverse movement assembly, the hook assembly moves upward on the lower track 3, so that the hook assembly lifts the graphite boat and moves vertically upward to detach from the tank body 2, and reaches the next target tank body 2 under the action of the lower transverse movement assembly, and the boat placing action is repeated.

[0044] When an abnormality occurs and causes the tank to be blocked, after the hook assembly reaches the destination tank body 2 and completes the boat-taking action, the hook assembly will carry the graphite boat and continue to move vertically upward, and move from the lower track 3 to the upper track 5, so as to reach the upper side of the temporary storage rack 4. Then the upper transverse movement assembly works, thereby driving the hook assembly on the upper track 5 to move horizontally, and the hook assembly drives the graphite boat to move directly above the temporary storage rack 4. The hook assembly moves downward on the upper track 5, and after placing the graphite boat on the temporary storage rack 4, the hook assembly detaches from the graphite boat and leaves the temporary storage rack 4, so as not to affect the original tank body to continue cleaning the next set of graphite boats. After the tank blockage is alleviated, the hook assembly promptly lifts the graphite boat on the temporary storage rack 4 to the next destination tank to continue the cleaning process until the entire cleaning process is completed.

[0045] The utility model provides a graphite boat cleaning device, the purpose of which is to reduce the situation where the graphite boat is over-washed when the tank is blocked due to external factors or abnormal manipulators, occupying the cleaning tank and wasting work efficiency.
