Comprehensive above-mentioned and combine accompanying drawing, the operation principle in the face of the two-way intermittent transmission of the present invention mechanism 100 is described in detail down:
Directly over the moving seat 1 of said holder of said two-way intermittent transmission mechanism 100 heater 500 is installed; Said heater 500 is tabular; And be parallel to each other with the moving seat 1 of said holder; During work, intake roller 300 rotates along a direction, and said substrate 200 is carried on the intake roller 300 and along the b direction and moves.In the time of directly over said substrate 200 moves to said intake roller 200, said intake roller 200 stops operating, and said rotating shaft electric motor 52 rotates and drives said eccentric wheel 53; Said eccentric wheel 53 rotates; Because said eccentric wheel 53 radiuses are different, when the wheel face of said eccentric wheel 53 was raised said roller 33 with the wheel face slide relative of said roller 33, said roller fixed head 34 rose and also promotes said lifting support 31 risings; And then promote the moving seat 1 of said holder and rise; When the moving seat 1 of said holder rises to the horizontal plane of said substrate 200 said substrate 200 held up and continue to rise, when the maximum side of said eccentric wheel 53 radiuses turned to peak, said rotating shaft electric motor 52 stopped operating; At this moment, the moving seat 1 of said holder arrives peak and stops to rise.Simultaneously, said lead screw motor 41 is rotated and is driven said ball screw 42, and said ball screw 42 rotates said feed screw nut 43 is moved along the b direction, and then drives the moving seat of said holder 1 along continuous straight runs to the translation of b direction through said transverse slat 13 and said support arm 12.In the time of directly over the moving seat 1 of said holder moves to said heater 500, said lead screw motor 41 stops operating, and makes the moving seat 1 of said holder stop translation.At this moment, said rotating shaft electric motor 52 startups are rotated further, and a side and said roller 33 that said eccentric wheel 53 radiuses are little are tangent, and 1 time said substrate 200 of general who has surrendered of the moving seat of holder described in this process is positioned over said heater 500 tops and heats.After heating is accomplished; Said rotating shaft electric motor 52 rotates to drive and stops after said eccentric wheel 53 holds up said substrate 200; Said lead screw motor 41 rotate continue with said substrate 200 move to output roller 400 directly over after stop; Said rotating shaft electric motor 52 rotates said substrate 200 declines again and is positioned on the said output roller 400, and said output roller 400 rotates sends said substrate 200 into subsequent processing.At last, said lead screw motor 41 drives said ball screw 42 to counter-rotation, makes the moving seat 1 of said holder move to original position, prepares next substrate of transmission.
Because the present invention drives said rotating shaft 51 through using a rotating shaft electric motor 52, makes said rotating shaft 51 drive some said eccentric wheels 53 simultaneously, utilize that different radii has the characteristics of differing heights on the said eccentric wheel 53 when rotating; Make a plurality of said elevating mechanisms 3 realize moving up and down, thereby moving seat 1 of said holder and said horizontal mobile mechanism 4 can be risen or descend simultaneously, utilize said lead screw motor 41 to drive said ball screw 42 again and drive said feed screw nut 43; The moving seat 1 of said holder can level be moved around, and, make the moving seat 1 of said holder of bearing substrate 200 realize rising off and on or descending through rotating the intermittence of control motor; And move around off and on; Thereby realize being input on the said heater 500 substrate 200 and outwards output again after heating, whole process automation degree is high, can reduce labour intensity greatly; And utilize said ball screw 42 to drive; The moving seat 1 of said holder is moved can greatly improve production efficiency accurately, fast, reduces production costs.
The operation principle of input, output roller 300,400 and heater 500 that the two-way intermittent transmission of the present invention mechanism 100 is involved is well known to those of ordinary skill in the art, no longer does detailed explanation at this.
Above disclosedly be merely preferred embodiments of the present invention, can not limit the present invention's interest field certainly with this, the equivalent variations of therefore doing according to claim of the present invention still belongs to the scope that the present invention is contained.
