Embodiment Construction
[0012] The specific implementation cases of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.
[0013] The first step: place the size parts 4 to be assembled, the right small parts 8, and the left small parts 10 on the part loading seat 13;
[0014] Step 2: Move the mechanical arm so that the clamp is located above the tool table, and control the opening and closing of the clamp so that it can pick up the adsorption needle. Control the movement of the mechanical arm, move the clamp that has picked up the adsorption needle to the part loading seat 13, turn on the vacuum generating device, absorb the right micro-sized part 8 on the part loading seat 13, and move it to the assembly fixed base 5 above;
[0015] Step 3: Place the right tiny part 8 above the right diameter hole 15 on the assembly and fixing base 5, and keep it parallel to the edge of the assembly and fixing base 5 under the detection of th...

The invention belongs to the technical field of precise assembly, in particular to an assembly method for miniature parts. The assembly method for the miniature parts is characterized by comprising the steps of firstly placing a miniature spring piece onto an assembly base with a vacuum adsorption device, opening a vacuum adsorption solenoid valve after the position is well adjusted, adsorbing and fixing the miniature part with the size being several millimeters by a diameter hole positioned in the base, spotting an adhesive, operating an manipulator to pick the miniature parts with the sizes being dozens of microns, adjusting the position, placing onto the miniature parts with the sizes being several millimeters, rotating a swing part, adjusting a pressure plate, and ensuring that an adsorption block of a clamp, the miniature parts and the base are fixed on an assembly clamp unit at the same time, so the positions and gestures of the miniature parts are kept, the method is suitable for the assembly of the miniature pars, the positions of the miniature parts can be fixed in the assembly process without disturbance and deformation, and the assembly precision is improved.
Description
technical field [0001] The invention belongs to the technical field of precision assembly, and relates to an assembly method of miniature parts. Background technique [0002] Precision assembly is the key to the manufacture of precision micro-miniature products. In recent years, domestic and foreign researches on automatic assembly systems and assembly methods for micro-miniature parts have achieved certain results. However, for the precise assembly of multiple micro-small parts with large size spans, different shapes, and relative position and attitude requirements, such as rigid parts with a large size of tens of millimeters, and flexible parts with a small size of a few millimeters, traditional The best assembly method is to assemble relatively large parts first, and then assemble smaller parts. With this assembly method, the positions of the post-assembled parts with smaller dimensions are not easy to fix and are easily disturbed and deformed by force during the assembl...
