the first step is as follows: the turnover mechanism 41 clamps the intermediate component from the assembly base 14, and when clamping, the turnover fingers 4111 first extend into the allowance port 141, then clamp the intermediate component and move out, and finally the turnover mechanism 41 turns the intermediate component 180 °.
The second step is that: the rotary clamp 42 is moved to the upper part of the middle assembly, the overturning clamp finger 4111 is located in the gap 4255 of the assembling clamp 425, after the clamping head 4253 clamps the middle assembly, the rotary clamp 42 is moved to the upper part of the vision camera 431, and the middle assembly is rotated to a target position according to the angle deviation detected by the vision camera 431.
The third step: the shell clamp 52 moves the shell 8 above the jacking mechanism 44, and the mounting hole 81 of the shell 8 is opposite to the jacking head 441; at the same time, the rotary clamp 42 moves the intermediate assembly above the housing 8, with the feelers of the lighter 6 facing the mounting holes 81 and the inner hole 4411 of the head 441.
The fourth step: the lifting head 441 is lifted to support the igniter 6, and the probe of the igniter 6 extends into the inner hole 4411 of the lifting head 441. The rotary clamp 42 and the jacking head 441 synchronously move downwards, and after the middle assembly is placed in the mounting hole 81 of the shell 8, the rotary clamp 42 releases the middle assembly.
The utility model discloses can realize the high-efficient assembly of ignition device 6, packing ring 7 and casing 8, and can effectively reduce the destruction to the product in assembling process.
The foregoing is only a preferred embodiment of the present invention, which is illustrative, not limiting. Those skilled in the art will appreciate that many variations, modifications, and equivalents may be made thereto without departing from the spirit and scope of the invention as defined by the appended claims.
