[0022] Technical effects and advantages of this application:

[0023] 1. Compared with the prior art, the three-dimensional multi-angle assembly device and the assembly method of the refrigerator can fit tightly on the curved glass during the process of adsorbing and clamping the curved glass, so that the special-shaped curved glass can be stably clamped to avoid the risk of the glass falling off. The fixed suction cup rotates in the rotating connection groove by the rotating adjustment block to complete the angle adjustment of the fixed suction cup. When the rotating adjustment block moves, it moves and slides by squeezing the telescopic adjustment rod, and the telescopic adjustment rod is telescoped in the fixed connection tube and the telescopic fixing sleeve by the telescopic spring, so that the fixed suction cup can be tightly fitted and fixed to the curved glass.

[0024] 2. Compared with the prior art, the three-dimensional multi-angle assembly equipment and assembly method of the refrigerator can determine whether the fixed suction cup completely sucks the curved glass during the adsorption and clamping process, and can determine whether the curved glass is placed right side up or upside down according to the rotation angle of the fixed suction cup. The fixed suction cup can detect the air pressure between the fixed suction cup and the curved glass through a pressure sensor, thereby determining whether there is a gap between the fixed suction cup and the glass through the air pressure, and can determine whether the fixed suction cup grasps the curved glass. The telescopic length of the telescopic adjustment rod can be detected by a displacement sensor, and the bending angle of the curved glass can be determined according to the telescopic lengths of multiple sets of telescopic adjustment rods, thereby determining whether the curved glass is placed right side up or upside down.

[0025] 3. Compared with the prior art, the three-dimensional multi-angle assembly equipment and assembly method of the refrigerator can adjust the multi-angle position of the curved glass during the clamping installation process, so as to facilitate the installation and assembly of the curved glass. The flip cylinder drives the flip connection frame on the flip connection block and the suction cup connection frame connected thereto to flip, and the suction cup connection frame drives the suction cup connection block connected thereto and the curved glass adsorbed by the fixed suction cup to flip during the flipping process. The flip connection frame is driven by the telescopic push rod to rotate with the connecting shaft as the axis, and the flip connection frame rotates on the flip connection block with the active shaft as the axis during the rotation and movement. After the curved glass is flipped by ninety degrees, the curved glass can be turned and adjusted according to the direction of the curved glass being placed forward and reversed. The rotating motor drives the connecting turntable to rotate through the active shaft, and the active shaft rotates in the flip connection frame through the connecting bearing, and the suction cup connection frame can be driven by the connecting turntable to rotate, so that the curved glass can be rotated and adjusted in the up and down directions.

5. An assembly method of a three-dimensional multi-angle assembly device for a refrigerator, using the three-dimensional multi-angle assembly device for a refrigerator according to any one of claims 1 to 4, characterized in that: The assembly method comprises the following steps: Step 1: First, the external gas tank is connected to the suction cup connecting frame (5) through the gas receiving hole (52), and the installation work of the fixed suction cup (7) can be controlled by operating the operating handle (31) on the connecting frame (3), and the moving action and the fixed retracting action of the assembly device can be controlled by the remote control (32), so that the fixed suction cup (7) approaches the curved glass to be installed, and when the fixed suction cup (7) approaches the curved glass, the fixed suction cup (7) is rotated through the suction cup connecting block (6); Step 2: During the rotation of the plurality of fixed suction cups (7), the plurality of fixed suction cups (7) gradually fit the curved surface of the curved glass. During the fitting process, the fixed suction cups (7) squeeze the rotating adjustment block (73) to move and rotate in the rotating connection groove (65), and the rotating adjustment block (73) squeezes the telescopic adjustment rod (631) to telescopically move in the fixed connection tube (63).
