[0002] During the photovoltaic and semiconductor product manufacturing process, silicon wafers are cut from raw silicon. These wafers are contaminated by debris and cutting fluid, necessitating a wafer cleaning machine to clean and then dry the wafers. Typically, after cleaning the wafers, a slow-lifting mechanism is used to lift the basket containing the wafers for drainage. To minimize draining time, the slow-lifting mechanism tilts one side of the basket as it is lifted.

At this time, the bracket and the flower basket on the bracket are in the trough body; when the process time is up, the first driving mechanism is used to drive the bracket and the second driving mechanism connected to the bracket and the flower basket loaded with silicon wafers placed on the bracket to move upward. When the flower basket reaches a certain height, the second driving mechanism provided at the bottom of the bracket is used to lift the horizontal flower basket to an inclined state, so that the inclined flower basket is dehydrated / drained.

[0005] However, the slow pulling device and the photovoltaic cleaning equipment having the same still have at least the following deficiencies during actual use, in other words, these are the technical problems to be solved by the present utility model.

[0006] Its second driving mechanism needs to enter the cleaning fluid, so it is easily corroded, and its effective service life is greatly shortened.

[0007] Therefore, in summary, there is an urgent need for a new type of robotic arm lifting device and photovoltaic cleaning equipment with the same to solve the barriers of existing technologies. Utility Model Content

DETAILED DESCRIPTION

[0030] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0031] As attached Figure 1-6 As shown, a robotic arm lifting device comprises a lifting plate unit 1 for hanging the distal ends of two groups of flower baskets a, and a lifting rod unit 2 arranged on the lifting plate unit 1 and located above the flower baskets a and for lifting the proximal ends of the two groups of flower baskets a.

[0032] In this embodiment, the silicon wafer b is inserted into the flower basket a. The number of columns and rows of the flower baskets a on the lifting plate unit 1 can be arranged as needed. The two ends of the flower basket a are connected to the lifting plate unit 1 and the lifting rod unit 2, respectively. To improve the efficiency of the lifting rod unit 2, two rows of flower baskets a are provided on the lifting plate unit 1. The distal end of the flower basket a is fixed to the lifting plate unit 1, and the proximal end of the flower basket a is movably connected to the lifting rod unit 2, so that the lifting rod unit 2 can simultaneously lift one end of the flower basket a. The lifting plate unit 1 can lift the flower basket a from the cleaning tank 11 by moving upward, at which time the flower basket a is in a horizontal state. The lifting rod unit 2 then moves to lift one side of the flower basket a, thereby facilitating the tilting of the flower basket a for easier drainage.

[0033] The lifting plate unit 1 includes a lifting block 101, a top horizontal plate 102 provided on the lifting block 101, and a fixed hanging plate 103 provided on the top horizontal plate 102 and used to hang the far ends of the two groups of flower baskets a.

[0034] In this embodiment, the lifting block 101 is used to move the top horizontal plate 102 up and down, which can be achieved through motor drive or manual adjustment. The top horizontal plate 102 is used to mount the lifting rod unit 2. The fixed hanging plates 103 are provided on both sides of the top horizontal plate 102 and are used to hang the distal ends of two sets of flower baskets a. One side of the flower baskets a is fixedly connected. The flower baskets a can be arranged in several rows along the vertical direction of the top horizontal plate 102.

[0035] The lifting rod unit 2 includes a vertical cylinder 201 provided on the top horizontal plate 102, a vertical rod 202 provided on the vertical cylinder 201, and a movable hanging plate 203 provided on the vertical rod 202 and used to lift the two groups of flower baskets a near their ends.

[0036] In this embodiment, the vertical cylinder 201 serves as a driving device for controlling the vertical rod 202. When the vertical rod 202 extends and retracts upward, it drives one side of the flower basket a on the movable hanging plate 203 upward, while the other side of the flower basket a is fixedly connected to the fixed hanging plate 103. Two lifting rod units 2 can be provided on the top horizontal plate 102 to lift the flower baskets a on the movable hanging plate 203, or a single lifting rod unit 2 can be provided to simultaneously lift two sets of flower baskets a.

[0037] The lifting plate unit 1 further includes a driving motor 104 , a vertical screw 105 disposed on the driving motor 104 and screwed to the lifting block 101 , and a housing 106 laterally engaged with the lifting block 101 .

[0038] In this embodiment, the lifting block 101 is mounted on the vertical screw 105. The drive motor 104 drives the lifting block 101 to move up and down. The lifting block 101 is connected to the top horizontal plate 102. The housing 106 engages the lifting block 101, protecting the lifting block 101 and ensuring smooth lifting. The drive motor 104 and the vertical screw 105 are one of the methods for driving the lifting block 101 up and down.

[0039] The lifting rod unit 2 further includes a transverse connecting plate 204 provided on the vertical rod 202 and used to connect a plurality of the movable hanging plates 203 . At least two of the movable hanging plates 203 are provided on the transverse connecting plate 204 .

[0040] In this embodiment, when multiple rows of flower baskets a are required to be arranged in the vertical direction of the top horizontal plate 102, the horizontal connecting plate 204 can connect the movable hanging plates 203 in the same direction, so that the vertical rod 202 can simultaneously lift two columns and multiple rows of flower baskets a, thereby improving the use effect of the vertical rod 202.

[0041] The lifting plate unit 1 further includes a fixed plate 107 disposed on the top transverse plate 102 and used for fixedly connecting the fixed hanging plate 103 and movably connecting the movable hanging plate 203 . The transverse connecting plate 204 is movably connected to the movable hanging plate 203 .

[0042] In this embodiment, the fixed plate 107 is disposed on the top horizontal plate 102 and is used to connect with the fixed hanging plate 103 and the movable hanging plate 203. The two fixed plates 107 on either side of the distal ends of the two flower baskets a are fixedly connected to the two fixed hanging plates 103; only one fixed plate 107 is provided on the proximal ends of the two flower baskets a for movable connection with the movable plate 103. The vertical rod 202 is fixedly attached to the transverse connecting plate 204, which is provided with the mounting waist hole 207. The movable hanging plate 203 is correspondingly provided with the connecting plate mounting rod 205. The connecting plate mounting rod 205 is loosely engaged with the mounting waist hole 207, thereby movably connecting the transverse connecting plate 204 to the movable hanging plate 203. Similarly, the movable hanging plate 203 is provided with a retaining hole 208. The fixed plate 107 near the two sets of flower baskets a is provided with a movable plate mounting rod 206. The movable plate mounting rod 206, through the clearance fit between the retaining hole 208, allows the movable hanging plate 203 to be movably connected to the fixed plate 107. A basket pressure sensor and an induction plate are respectively provided on the fixed plate 107 and the movable hanging plate 203 near the two sets of flower baskets a. These sensors trigger each other to detect whether a flower basket a is left in the washing tank. During normal operation, the transverse movable frame 12 drives the flower basket a on the lifting plate unit 1 to move to the cleaning tank 11 for processing. In the natural state, under the influence of gravity, the connecting plate mounting rod 205 and the movable plate mounting rod 206 are respectively located at the upper ends of the mounting waist hole 207 and the limiting waist hole 208. When the flower basket a is left in the cleaning tank 11, the remaining flower basket a contacts and lifts the flower basket a on the lifting plate unit 1. Under the influence of the lifting force, the connecting plate mounting rod 205 and the movable plate mounting rod 206 respectively move to the lower ends of the mounting waist hole 207 and the limiting waist hole 208, thereby causing the basket pressure sensor and the sensor sheet to trigger each other, thereby detecting that the flower basket a is left in the cleaning tank 11. In order to protect the flower basket a on the lifting plate unit 1, the lowering operation of the lifting plate unit 1 needs to be stopped.

[0043] The fixed hanging plate 103 and the movable hanging plate 203 are provided with clearance fitting rods 3 for hanging the flower basket a.

[0044] In this embodiment, the clearance-fitting rod 3 is used to suspend the flower basket a. At the same time, the clearance-fitting rod 3 is clearance-fitted with the flower basket a. When the vertical rod 202 lifts one side of the flower basket a, the reserved gap is sufficient to allow the flower basket a to be tilted in a high or low position without damaging the flower basket a or affecting the normal lifting of the vertical rod 202.

[0045] At least two of the vertical rods 202 are disposed on the transverse connecting plate 204 .

[0046] In this embodiment, in order to ensure the stability and lifting effect of the vertical rods 202 in lifting the flower basket a, the number of the vertical rods 202 on the transverse connecting plate 204 is no less than two.

[0047] A photovoltaic cleaning device comprises the mechanical arm lifting device.

[0048] In this embodiment, the photovoltaic cleaning equipment includes the robotic arm lifting device.

[0049] The cleaning device further comprises a cleaning tank 11 and a transversely movable frame 12 disposed on the cleaning tank 11 and used for mounting the lifting plate unit 1 .

[0050] In this embodiment, the cleaning tank 11 is used to clean the silicon wafer b on the flower basket a. The cleaning tank 11 is usually provided with multiple ones to clean the flower basket a multiple times. The function of the horizontal movable frame 12 is to move the flower basket a on the lifting plate unit 1 to the next procedure to realize automated processing.
