[0028] As Figures 1 to 4 shown, an automatic assembly mechanism for a rotary mirror motor includes an assembly station base 1, a screw feeding mechanism 2, a screwdriver unit, and a rotary mirror motor assembly 10. The rotary mirror motor assembly 10 is installed on the assembly station base 1. The screw feeding mechanism 2 is located on one side of the assembly station base 1 along the negative Y-axis direction, and the screwdriver unit is located on one side of the assembly station base 1 along the negative X-axis direction.

[0029] The screwdriver unit includes a screwdriver module base 3 and a screwdriver mechanism 6. The screwdriver X-axis module 4, the screwdriver Z-axis module 5, and the screwdriver Y-axis module 8 installed on the screwdriver module base 3 can respectively drive the screwdriver mechanism 6 to move in the X-axis, Z-axis, and Y-axis directions. A positioning vision mechanism 7 is installed on one side of the screwdriver mechanism 6.

[0030] A rotary mirror to-be-assembled mechanism 9 is installed on one side of the assembly station base 1 along the positive X-axis direction. The rotary mirror motor assembly 10 successively includes a rotary mirror motor 17 and a rotary mirror motor base 18 from top to bottom. The rotary mirror motor base 18 is installed on the lower rotary mirror to-be-assembled mechanism 9, and a plurality of motor fixed mounting holes 19 are provided on the rotary mirror motor base 18.

[0031] On one side of the assembly station base 1 along the negative X-axis direction, a lifting mechanism 16 is installed. The lifting mechanism 16 is a cylinder, a hydraulic cylinder or an electric push rod. The driving end at the top of the lifting mechanism 16 is connected to one side of the angle deviation correction mechanism substrate 14 above along the negative X-axis direction. On one side of the angle deviation correction mechanism substrate 14 along the positive X-axis direction, an angle deviation correction driven shaft 11 is rotatably installed. At the middle position of the bottom of the angle deviation correction mechanism substrate 14, a deviation correction motor 15 is installed. The driving end at the top of the deviation correction motor 15 is connected to the angle deviation correction driving shaft 13 above. The angle deviation correction driving shaft 13 is connected to the angle deviation correction driven shaft 11 through an angle transmission mechanism 12. The angle transmission mechanism 12 is a belt transmission mechanism, a chain transmission mechanism or a gear meshing transmission mechanism. The angle deviation correction driven shaft 11 and the angle deviation correction driving shaft 13 are respectively installed on the angle deviation correction mechanism substrate 14 through bearings.

[0032] At the bottom of the angle deviation correction driven shaft 11, an angle deviation correction pressing head is installed. The angle deviation correction pressing head is located directly above the rotating mirror motor 17. The angle deviation correction pressing head is a flexible pressing head.

[0033] The relationships among the components of the rotating mirror automatic assembly mechanism of the present utility model are as follows:

[0034] The assembly station base 1, the screw feeding mechanism 2, and the screwdriver module base 3 are fixed to the equipment table / desktop by screws. Depending on the stroke and process requirements, the screwdriver module adopts a cantilever or gantry mechanism. In this example, the cantilever layout is adopted. The screwdriver Y-direction module 8 is fixed to the screwdriver module base 3 by screws; the screwdriver X-direction module 4 is fixed to the slide plate of the screwdriver Y-direction module 8 by screws; correspondingly, the screwdriver Z-direction module 5 is fixed to the slide plate of the screwdriver X-direction module 4 by screws, forming the XYZ three-axis movement system of the entire mechanism.

[0035] On the slide plate of the screwdriver Z-direction module 5, the screwdriver mechanism 6 and the positioning vision mechanism 7 are respectively fixed by screws.

[0036] Regarding the mating relationship of the rotating mirror assembly station, the lifting mechanism 16 is fixed to the assembly station base 1 by screws, and the angle deviation correction mechanism substrate 14 is fixed to the moving end of the lifting mechanism 16 by screws. The deviation correction motor 15 is fixed to the angle deviation correction mechanism substrate 14 by screws and is directly connected to the angle deviation correction driving shaft 13; the angle deviation correction driven shaft 11 with a flexible pressing head is also fixed to the angle deviation correction mechanism substrate 14 through a bearing mechanism. The power is transmitted between the angle deviation correction driven shaft 11 and the angle deviation correction driving shaft 13 through an angle transmission mechanism 12, such as belt transmission, chain transmission, gear meshing and other transmission methods.

[0037] The mirror rotating mechanism to be assembled 9 is placed on the assembly station base 1 manually or by other automated means, and the mirror rotating motor assembly 10 is placed on the mirror rotating mechanism to be assembled 9 manually or by other automated means.

[0038] When the mirror rotating motor and mirror automatic assembly mechanism is working, first, the mirror rotating mechanism to be assembled 9 and the mirror rotating motor assembly 10 are sequentially placed on the assembly station base 1 manually or by other automated means to complete the material preparation. At this time, the angle between the mover and the stator mechanism of the mirror rotating motor assembly 10 is a random value.

[0039] After the process is started, the lifting mechanism 16 drives the angle deviation correction mechanism base plate 14 to descend, so that the flexible pressing head of the angle deviation correction driven shaft 11 fixed on the angle deviation correction mechanism base plate 14 through the bearing mechanism presses on the upper end surface of the mirror rotating motor assembly 10. While preventing damage to the appearance of the mirror rotating motor assembly 10, the flexible end surface of the angle deviation correction driven shaft 11 also restricts the five-degree-of-freedom of the mover of the mirror rotating motor assembly 10, and only allows the mover of the mirror rotating motor assembly 10 to rotate controllably only in the horizontal plane during the angle deviation correction work.

[0040] Then, the positioning vision mechanism 7, driven by the XYZ three axes of the screwdriver X-direction module 4, the screwdriver Y-direction module 8, and the screwdriver Z-direction module 5, calculates the angle of the mover of the mirror rotating motor assembly 10 from above. Then, the deviation correction motor 15 performs corresponding rotation actions according to the calculation results of the vision positioning data, drives the angle deviation correction driven shaft 11 to perform angle deviation correction through the direct connection of the angle deviation correction driving shaft 13 and the angle transmission mechanism 12, so that the angle of the mirror rotating motor 17 rotates to the set position and can maintain the position, exposing the assembly positioning holes of the mirror rotating motor base 18 (i.e., the motor fixing and mounting holes 19).

[0041] Then, the screwdriver mechanism 6, driven by the XYZ three axes of the screwdriver X-direction module 4, the screwdriver Y-direction module 8, and the screwdriver Z-direction module 5, first goes to the screw feeding mechanism 2 to pick up the screws for assembly. Then, the screwdriver mechanism 6, driven by the XYZ three axes of the screwdriver X-direction module 4, the screwdriver Y-direction module 8, and the screwdriver Z-direction module 5, directly performs the screw assembly work on the exposed assembly positioning holes of the mirror rotating motor assembly 10 (i.e., the motor fixing and mounting holes 19) according to the positioning data of the previous positioning vision mechanism 7. According to the number of screws to be assembled, the actions of picking up the screws for assembly - screw assembly are cycled in sequence until all the screws are assembled.

[0042] Among them, the structures and working principles of the above-mentioned screwdriver mechanism 6, mirror rotating motor assembly 10, positioning vision mechanism 7 and other devices are all conventional technologies in the field.

[0043] If production traceability is required, at this time, the positioning vision mechanism 7 can be driven by the XYZ three axes of the screwdriver X-axis module 4, the screwdriver Y-axis module 8, and the screwdriver Z-axis module 5 to visually inspect the assembly condition of the rotary mirror motor assembly 10 from above and record the assembly information for uploading to the production management system.

[0044] Finally, the screwdriver mechanism 6 returns to the initial waiting position under the drive of the XYZ three axes of the screwdriver X-axis module 4, the screwdriver Y-axis module 8, and the screwdriver Z-axis module 5; the lifting mechanism 16 also rises to lift the angle deviation correction mechanism substrate 14, so that the angle deviation correction driven shaft 11 is disengaged from the rotary mirror motor assembly 10, and then the assembled rotary mirror to-be-assembled mechanism 9 - rotary mirror motor assembly 10 integrated finished product material is taken away manually or by other automated means.

[0045] So far, the automatic assembly process of the rotary mirror motor rotary mirror has been completed. According to subsequent requirements, the equipment is prepared for the next working cycle.

[0046] By using a flexible angle deviation correction mechanism and under the control of visual positioning, precise angle deviation correction of the rotary mirror motor can be performed, so that the fixed hole positions are exposed when the rotary mirror motor is assembled to achieve automated screw locking assembly work. Through the means of parameter monitoring of the automatic screwdriver and visual inspection, the automatic upload of various assembly parameters can be realized, and the traceability of the assembly results can be achieved.
