The servo motor is used for driving the lead screw and further driving the mounting box to ascend and descend, so that potential quality safety hazards caused by power transmission of a synchronous belt are avoided; the installation mode that a vertical beam is indirectly installed on an installation box in the prior art is omitted, the horizontal big arm is directly installed on the installation box, and the final droop amount of the end of the horizontal big arm can be effectively reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a flower basket lifting Y-axis robot used for the turnover of silicon wafers in the flower basket. Background Art

[0002] In the manufacturing process of solar cells, the surface of silicon wafers has been adsorbed with various impurities after being processed through multiple processes such as slicing, grinding, chamfering, and polishing. Therefore, they need to be cleaned before diffusion to eliminate various pollutants and to make a velvet structure (velveting) that can reduce the reflection of sunlight on the surface. The cleanliness of the cleaning directly affects the yield and reliability of the solar cells. During the cleaning process, silicon wafers usually need to be loaded into baskets in batches, and then the baskets containing silicon wafers are lifted and lowered by a manipulator turnover device to achieve cleaning, transfer, drying, etc.

[0003] At present, the horizontal arm of the Y-axis robot in the industry is generally installed on a vertical beam, and the vertical beam is installed on the mounting box of the screw nut; the servo motor outputs power to the synchronous pulley, and the power is transmitted through the synchronous belt to drive the ball screw mechanism, thereby driving the screw nut mounting box to move up and down, realizing the lifting and lowering of the Y-axis robot arm; the structure of the above-mentioned prior art has the following shortcomings:

[0004] The traditional Y-axis robot used for Y-axis lifting of flower baskets transmits power through a synchronous belt, which has the risk of breakage and poses quality and safety risks to the equipment. Moreover, the horizontal arm of the Y-axis robot is connected to the screw nut mounting box through a vertical beam. The horizontal arm will accumulate and amplify the deformation of the vertical beam, causing the end of the horizontal arm to sag severely. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a flower basket lifting Y-axis robot, comprising a vertically arranged Y-axis spindle, a control box arranged on the Y-axis spindle and a servo motor controlled by the control box, a slide rail vertically and symmetrically arranged on the Y-axis spindle along the Y-axis, a mounting box installed between the slide rails on both sides through a slider, a screw rod arranged in the Y-axis and connected to the mounting box with a thread rotation, and a horizontal arm installed on the side of the mounting box in the X-axis;

[0006] The X-upward end of the screw rod is connected to the top plate of the Y-axis spindle through a rotating shaft, the screw rod is rotationally connected to the mounting box through a thread, and the other end of the screw rod is connected to the output end of the servo motor.

[0007] Wherein: the horizontal arm is installed on the side of the installation box through an L-shaped connecting plate and locking bolts.

[0008] Furthermore: a reducer is also arranged between the servo motor and the screw rod.

[0009] Furthermore: a coupling is also arranged between the reducer and the screw rod.

[0010] Further: a buffer corresponding to the top plate of the Y-axis spindle is provided at the upper end of the installation box.

[0011] Furthermore: a lifting height sensor is also provided on the installation box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The servo motor is used to drive the screw rod and then drive the installation box to rise and fall, replacing the synchronous belt drive method in the prior art, which solves the quality and safety risks of synchronous belt power transmission;

[0014] 2. The installation method of indirectly installing the horizontal boom on the installation box through the vertical beam in the prior art is cancelled, and the horizontal boom is directly installed on the installation box, which can effectively reduce the final sagging amount of the horizontal boom end.
