Initially, the first support block 3141 on the support plate 314 and the second support block 3151 on the vertical movable plate 315 are both supported below the two sides of the material tray 90; when the material tray is lowered, the support plate 314 moves backward to separate the first support block 3141 from the material tray 90, and only the second support block 3151 supports the material tray.

If the bearing is not installed in place, the material picking rod 42 will be lifted up and hit the shaft end of the buffer cylinder 453, causing the buffer cylinder 453 to move upward. The lifting and lowering of the shaft of the buffer cylinder 453 is detected by a sensor (not shown in the figure). When the sensor senses that the shaft of the buffer cylinder 453 is lifted up, it means that the bearing is not installed in place, that is, the gear box bearing combination is judged to be a defective product; otherwise, it is judged to be a good product.

[0061] In addition, a CCD camera 50 for detecting whether the bearing is oiled and a proximity sensor for determining whether there is a gasket under the bearing are provided at the corresponding bearing mounting mechanism 40 on the frame 10 (the proximity sensor can sense whether there is a metal gasket, not shown in the figure). A bad bearing collection component 60 for collecting unqualified bearings and a bad product collection component 70 for collecting unqualified products assembled in the tooth box bearing are also provided on the frame 10; the bad bearing collection component 60 is located on the side of the material picking rod 42, and includes a bad bearing collection bin 61 and a collection bin driving cylinder 62 for driving the bad bearing collection bin 61 to move (collecting bearings that are not oiled or / and do not have gaskets); the bad product collection component 70 is located on the side of the tail end of the tooth box conveying mechanism 20, and includes a bad product collection bin 71, a material picking suction cup 72, and a bad product transfer drive component 73 for driving the material picking suction cup 72 to reciprocate between the tail end of the tooth box conveying mechanism 20 and the bad product collection bin 71 (adopting a motor, a screw rod and a slider, the motor drives the screw rod to rotate, and the rotation of the screw rod drives the slider to move on the screw rod), the material picking suction cup 72 is installed on the output end (installed on the slider) of the bad product transfer drive component 73, and has a cylinder to drive it to rise and fall to pick up materials. The above-mentioned flip assembly +25 is arranged between the rear end of the tooth box conveying mechanism 20 and the defective product collection bin 71 to flip the defective products to a flat state for the material suction cup 72 to absorb and transfer.

[0062] In addition, a material moving mechanism 80 is provided between the above-mentioned material tray supporting device and the empty material tray recovery device, and is used to move the bearings that fall into the upper material tray of the transfer device to the bearing mounting mechanism. The material moving mechanism 80 includes a material picking component 81 and a material feeding component 82. The material picking component 81 is located above the transfer device, and the material feeding component 82 is connected between the material picking component 81 and the bearing mounting mechanism. The material taking assembly 81 includes a frame 811, a material taking clamp 812 that can move horizontally and rise and fall, a horizontal driving device 813 that drives the material taking clamp 812 to move horizontally, and a vertical driving device 814 that drives the material taking clamp 812 to rise and fall. The horizontal driving device 813 has a horizontal sliding plate 8131 that can slide horizontally on the frame 811; the vertical driving device 814 is installed on the horizontal sliding plate 8131, and the material taking clamp 812 is installed on the output end of the vertical driving device 814; the feeding assembly 82 is a belt transmission assembly, and the material taking clamp 812 reciprocates between the transfer device and the feeding assembly 82. Both the horizontal driving device 813 and the vertical driving device 814 adopt the matching mode of motor, screw rod and slider. This principle is a common mode and will not be repeated here; at the same time, a cylinder or other driving mode can also be adopted.

[0063] The assembly method of the gear box bearing assembly machine comprises the following steps:

[0064] S1, the tooth box conveying mechanism conveys the tooth box to the bearing installation mechanism, and the tooth box fixing device fixes the tooth box;

[0065] S2, stacking the trays carrying the bearings into the receiving area of ​​the tray supporting device in sequence; the vertical moving plate and the supporting plate cooperate with each other to drive the trays gradually downward to the transfer device;

[0066] S3, the transfer device drives the tray carrying the bearing to a position between the tray supporting device and the empty tray recovery device;

[0067] S4, the material taking component and the material conveying component cooperate to transfer the bearing on the material tray to the bottom of the bearing installation mechanism, and check whether the bearing is oiled and whether it has a gasket. If it is not oiled and / or has no gasket, the bearing is transferred to the bad bearing collection bin; the good product is installed in the gear box by the bearing installation mechanism;

[0068] S5. The tray with the bearing removed is moved to the empty tray recovery device for recovery;

[0069] S6. During the bearing installation process, the pick-up rod detects whether the bearing is installed in place. The gear box bearing assembly that is not installed in place will be transferred to the defective product collection bin;

[0070] S7. Good quality gear box bearing assemblies are discharged by the gear box conveying mechanism.
