[0002] Photovoltaic silicon wafers usually need to be cleaned during the production process. Usually, multiple photovoltaic silicon wafers are placed in a graphite boat, and then the multiple graphite boats are stacked and placed in a flower basket. Then, the flower baskets are manually placed in multiple cleaning tanks in the cleaning mechanism in turn. Since the flower baskets are large in size and heavy in weight, the labor intensity of manually carrying the flower baskets is high. Even some automatic handling systems must be used with suitable flower baskets, that is, the cleaning mechanism must be used with the flower basket, which undoubtedly increases the cleaning cost of photovoltaic silicon wafers. Patent CN116259564A discloses a cleaning system for photovoltaic silicon wafers, which is used to support the upper graphite boat by setting a reprinting device in the cleaning tank, so that multiple layers of graphite boats can be placed in the cleaning tank to replace the flower basket. However, due to the setting of the reprinting device, the internal space of the cleaning tank is occupied, the width of the cleaning tank is increased, and the cleaning tank cannot be used in places with limited site space.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0023] See attached Figure 1-3As shown, a cleaning tank in this embodiment includes a tank body 1 with an opening at the upper end, and the tank body 1 defines a cleaning chamber 11, and a graphite boat 2 is placed in the cleaning chamber 11 for cleaning. A flap device 3 is provided in the length direction of the cleaning chamber 11 for placing the graphite boat 2. Since the volume of the cleaning chamber 11 is relatively large, if only one layer of graphite boat 2 is placed, the cleaning chamber 11 will undoubtedly be wasted. Therefore, by providing a flap device 3, the flap device 3 can separate the cleaning chamber 11 to achieve the vertical spacing of the graphite boat 2 in the cleaning chamber 11, and the graphite boat 2 will not come into contact during the stacking process. This improves the utilization rate of the cleaning chamber 11. In addition, since a flap device is provided in the length direction of the cleaning chamber 11, the width of the cleaning tank will not be increased additionally, and the cleaning tank has a compact structure, which is suitable for workplaces with limited floor space for the cleaning tank.

[0024] See attached Figure 4 As shown, each flap device 3 includes at least one rotating rod 33 located in the cleaning chamber 11, and the rotating rod 33 rotates under the drive of the corresponding flip driving member 31, and the flip driving member 31 is fixed on the tank body 1 and is located outside the cleaning chamber 11. The flip driving member 31 is connected to the rotating rod 33 through a connecting rod assembly 32 to drive the rotating rod 33 to rotate. A support assembly 34 is fixed on the rotating rod 33 to rotate synchronously with it to achieve up and down flipping. The support assembly 34 is used to support the graphite boat 2 located on the second layer. When the graphite boat 2 located below the support assembly 34 is taken and placed, the support assembly 34 swings to a vertical state to avoid interfering with the taking and placing of the graphite boat 2 below. When the support assembly 34 swings to a horizontal state, the graphite boat 2 can be placed on the support assembly 34.

[0025] The flip device 3 is used to support the graphite boat 2 through a pair of support assemblies 34 that can be flipped up and down. When the graphite boat 2 under the support assembly 34 is placed, the flip driving member 31 drives the support assembly 34 to flip upward to a vertical state. The support assembly 34 now makes way for the graphite boat 2 below, and the graphite boat 2 can be placed under the support assembly 34. After the graphite boat 2 under the support assembly 34 is placed, the flip driving member 31 drives the support assembly 34 to flip downward to a horizontal state. At this time, the support assembly 34 separates the cleaning chamber 11, and the graphite boat 2 can be placed on the support assembly 34, so that the graphite boat 2 can be placed in multiple layers in the cleaning chamber 11.

[0026] In some embodiments, at least one group of flap devices 3 is provided, and two flip devices 3 mirror-imaged and arranged on both sides of the tank body 1 in the length direction form a group, and the two flip devices 3 in a group are located at the same height, and a group of flip devices 3 divides the cleaning tank into two layers, upper and lower layers, to support both ends of the graphite boat 2. The support components 34 of the flip devices 3 on both sides support both ends of the graphite boat 2 respectively. Since the flip devices 3 on both sides support a group of graphite boats at the same time, the pressure of the graphite boat 2 on a group of flip devices 3 is reduced, the stability of the graphite boat 2 is improved, and the service life of the flip devices 3 is extended.

[0027] In some embodiments, N groups of flipping devices 3 of different heights are provided. The support assembly 34 on each group of flipping devices 3 has a different height, and the support assembly 34 can divide the cleaning chamber 11 into N+1 layers, and the graphite boats 2 can be placed in the cleaning chamber 11 in N+1 layers from bottom to top. During the placement of the graphite boats 2, the support assembly 34 swings from bottom to top to a horizontal position in sequence.

[0028] In some embodiments, each set of flap devices 3 has two pairs of support components 34, so that the flap devices 3 can support two graphite boats 2 at the same time. When the graphite boat 2 is placed at the bottom of the cleaning tank, the support components 34 of the two sets of flap devices 3 are in a vertical state. After the two graphite boats 2 are placed at the bottom of the tank, the support components 34 of the two sets of flap devices 3 are flipped down to a horizontal state. When the support components 34 are flipped to a horizontal state, two more graphite boats 2 can be placed on the two sets of flap devices 3. When the cleaning is completed, the unloading device first takes out the graphite boat 2 on the flap device 3, and then the support components 34 of the flap device 3 swing to a vertical state, and the unloading device then takes out the graphite boat 2 at the bottom of the tank. Each set of flap devices 3 can also have three, four or five pairs of support components 34. The specific number of support components 34 set on each flip device 3 depends on the actual situation and is not limited in this application.

[0029] In some embodiments, the support assemblies 34 on the same rotating rod 33 are arranged in parallel, that is, all the support assemblies 34 can be located in the same horizontal plane, that is, the cleaning chamber 11 can be divided into two layers, upper and lower. In some embodiments, the support assembly 34 includes a support rod 341 and a support plate 342 connected to the support rod 341, and the two support rods 341 are symmetrically arranged on both sides of the support plate 342 and connected to the rotating rod 33. The rotating rod 33 can drive the support plate 342 to flip. The graphite boat 2 is supported by the support plate 342. By setting the support plate 342, graphite boats 2 of different specifications can be supported, thereby improving the application range of the cleaning tank.

[0030] In some embodiments, a through hole 3421 is provided on the surface of the support plate 342 against the boat foot, and the through hole 3421 connects the boat foot and the cleaning tank. Since the cleaning tank stores cleaning agent during cleaning, the through hole 3421 is provided on the support assembly 34 so that the cleaning agent can clean the boat foot and avoid the occurrence of a cleaning dead corner when the graphite boat 2 is cleaned.

[0031] In some embodiments, the connecting rod assembly 32 includes a swing rod 1 321, a rotating rod 322, a swing rod 2 323, a linkage rod 324 and a swing rod 3 325 connected in sequence. The flip driving member 31 includes a telescopic shaft, the flip driving member 31 is hinged to the tank body 1, one end of the swing rod 1 321 is hinged to the telescopic shaft of the flip driving member 31, and the other end of the swing rod 1 321 is fixedly connected to the rotating rod 322. The rotating rod 322 vertically passes through the cleaning tank and is located at the upper end of the cleaning tank. The swing rod 2 323 is arranged parallel to the swing rod 1 321 and one end is fixedly connected to the part of the rotating rod 322 located in the cleaning tank, and the other end is hinged to the end of the linkage rod 324, the other end of the linkage rod 324 is hinged to one end of the swing rod 325, and the other end of the swing rod 325 is fixedly connected to the rotating rod 33.

[0032] When the flip driving member 31 is extended and retracted up and down, the swing rod 322 is pushed to rotate by the swing rod 1 321, thereby driving the swing rod 322 to rotate along its own axis. During the rotation process, the swing rod 322 drives the swing rod 2 323 to flip up and down synchronously with the swing rod 1 321. During the flip process, the swing rod 2 323 drives the swing rod 3 325 to flip up and down through the connecting rod 324. Since the swing rod 3 325 and the rotating rod 33 are fixed, the swing rod 3 325 drives the rotating rod 33 to rotate along its own axis during the up and down swing process, thereby realizing the up and down flipping of the support assembly 34. The flip driving member 31 is located outside the cleaning chamber 11, and drives the rotating rod 33 located in the cleaning chamber 11 to rotate (that is, the support assembly 34 swings) through the connecting rod assembly 32. Moreover, through the connecting rod assembly 32, the rotating rod 322 located above the cleaning liquid can drive the rotating rod 33 located in the cleaning liquid to rotate, thereby preventing the cleaning liquid from leaking from the rotating rod 322.

[0033] In some embodiments, the connecting rod assembly 32 further includes a bearing 326, which is sleeved on the rotating rod 322 and is located in the through hole of the tank body 1 when the rotating rod 322 passes through the tank body 1, connecting the tank body 1 and the rotating rod 322. The arrangement of the bearing 326 reduces the friction between the rotating rod 322 and the tank body 1 during the rotation process, which facilitates the flipping of the flip assembly 3.

[0034] Working process: The graphite boat 2 is directly clamped by the manipulator and placed in the cleaning tank. A flipping device is provided in the cleaning tank, and the support plate 342 is driven to flip by the flipping drive 31. When the graphite boat 2 located under the support plate 342 is taken and placed, the support plate 342 swings to a vertical state to avoid interference with the taking and placing of the graphite boat 2 below. When the support plate 342 swings to a horizontal state, the graphite boat 2 can be placed on the support plate 342, which greatly improves the utilization rate of the cleaning tank. After cleaning, the graphite boat 2 is taken out of the cleaning tank by the transfer mechanism.
