Along the second turntable 2, the frame is equipped with a second detection device, a long tooth assembly feeding device, a box cover feeding device, a double-headed screw machine 82, and a feeding device.

[0021] Specifically, there are six first positioning devices 11, which are evenly distributed on the first turntable 1, and six second positioning devices 21, which are evenly distributed on the second turntable 2. The first turntable 1 and the second turntable 2 are horizontally alternated and rotated at 60-degree intervals. That is, the horizontal height of the two turntables is preferably the same. The two turntables are set relatively close to each other without interfering with each other. Each time the two turntables rotate, the positions of the two adjacent first positioning devices 11 (B) and second positioning devices 21 (A) remain unchanged.

[0022] The long tooth assembly feeding device includes a first vibrating plate with a first conveying track mounted on the frame, a grease cylinder 103 fixed on the frame, a first gantry robot 101 that transfers the long tooth assembly on the first conveying track to the grease cylinder 103, and a second gantry robot 102 that transfers the long tooth assembly on the grease cylinder 103 to the assembly to be assembled on the second positioning fixture 21 at the corresponding position; the bottom of the grease cylinder 103 is connected to the grease pump 105 through a hose 104.

The opening of the grease cylinder 103 is provided with a positioning step that is adapted to the long tooth assembly. Initially, the grease cylinder 103 is filled with grease. After the first gantry robot 101 moves the long tooth assembly onto the grease cylinder 103, grease adheres to the gears of the long tooth assembly. Then, the second gantry robot 102 moves the long tooth assembly on the grease cylinder 103 to the assembly part on the second positioning fixture 21 at the corresponding position, thereby realizing automated grease addition.

[0024] The gear feeding device includes a second vibrating disc with a second conveying track mounted on the frame, and a third gantry robot 31 on a first positioning device 11 that moves the gear to the corresponding position. The shaft of the gear moves upward. The first positioning device 11 is provided with a groove that matches the gear. The groove matches the bottom of the gear so that the gear can be limited on the first positioning device 11. The box feeding device includes a third vibrating plate with a third conveying track mounted on the frame, and a fourth truss manipulator 41 that sends the box to the corresponding position on the first positioning fixture 11 and the assembly to be assembled. The box has a hole and the shaft with a gear has a stepped protrusion. At this time, the box is conveyed upside down, and the shaft passes through the hole and is limited by the step, so that the box is limited on the first positioning fixture 11.

[0025] The first detection device includes a first sensor 51 mounted on the frame, used to detect whether a box cover on the first positioning device 11 at the corresponding position is upside down on the gear with shaft; The aforementioned rocker arm feeding device includes a fourth conveying track and a fourth vibrating plate mounted on the frame, a fifth truss manipulator 52 on the first positioning fixture 11 that conveys the rocker arm to the corresponding position, and the rocker arm also has holes that limit it on the protrusion of the step.

[0026] The aforementioned flipping and feeding device includes a sixth gantry robot 61 mounted on the frame, used to flip and transfer the component to be processed on the first positioning fixture 11 at the corresponding position to the adjacent second positioning fixture 21. The gantry robot adopts existing technology. Existing robots have flipping functions and some do not. Other robots in this utility model may not have flipping functions, but the fifth gantry robot 52 needs to have flipping functions. A rotary cylinder is set at the end of the robot, and the rotary cylinder is connected to the gripper to achieve a 180-degree flip so that the box that is upside down on the first positioning fixture 11 is transferred to the second positioning fixture 21 in the correct position. The upper surface of the second positioning device 21 has a groove that matches the box body in the correct position (after being rotated 180 degrees) to limit the position of the box body.

[0027] The second detection device includes a second sensor 71 mounted on the frame, used to detect whether the flipped box exists on the second positioning device 21 at the corresponding position.

[0028] The box cover feeding device includes a sixth vibrating plate with a sixth conveying track mounted on the frame, and a seventh truss robot 81 that sends the box cover to the assembly part on the second positioning fixture 21 at the corresponding position; The double-headed screwdriver 82 includes two single-headed screwdrivers mounted on a frame, which screw screws from the cover into the box body to fix the cover to the box body.

[0029] The unloading device includes an eighth gantry robot 91 mounted on the frame, used to transfer the assembled workpiece from the second positioning fixture 21 at the corresponding position to the unloading area.

[0030] Working principle: Initially, the two turntables rotate at corresponding time intervals, and there are no workpieces on the first positioning fixture 11 and the second positioning fixture 21. The third gantry robot 31 moves the gear with shaft to the first positioning fixture 11, and the first turntable 1 rotates to the next station. The fourth gantry robot 41 moves the box (which is upside down during the vibratory feeder transport) to the first positioning fixture 11. The first turntable 1 rotates, and the first sensor 51 detects whether the workpiece is present. The first turntable 1 rotates to the next station. The fifth gantry robot 52 moves the rocker arm to the first positioning fixture 11, and the first turntable 1 rotates to the next station. The single-head screw machine 53 screws in the screws, and the first turntable 1 rotates to the next station. The sixth gantry robot 61 flips the upside-down box to its correct position and moves it to the nearest second positioning fixture 21. Each station cycles in this manner. The second turntable 2 rotates to the next station. The second sensor 71 detects whether the workpiece is still there or whether it has been successfully flipped. The second turntable 2 rotates to the next station. The first gantry robot 101 transfers the long tooth assembly to the grease cylinder 103, and grease is applied to the gears of the long tooth assembly. Then, the second gantry robot 102 transfers the long tooth assembly on the grease cylinder 103 to the part to be assembled on the second positioning fixture 21 at the corresponding position. The second turntable 2 rotates to the next station. The seventh gantry robot 81 delivers the box cover to the part to be assembled. The second turntable 2 rotates to the next station. The double-headed screw machine 82 screws in the screws. The second turntable 2 rotates to the next station. The eighth gantry robot 91 transfers the assembled part to the unloading area. Each station cycles in this manner, thus realizing fully automated production.
