Description
Technical field
The utility model relates to the plate feeding device of printed circuit board (PCB) (PCB) wet process equipment.
Background technology
The mode of plate feeding device is in existing printed circuit board (PCB) (PCB) wet process equipment: horizontal many upper roller shafts and bottom roller axle, on the axle roller is housed, the relatively rotating of upper and lower roller shaft roller drives the pcb board be clipped between the upper and lower roller and carries between upper and lower live roller.The driver train form mainly contains following dual mode: monolateral transmission: refer to drive the main driving axle that is arranged in plate feeding device one side with a motor via reducer, sprocket chain bar, main driving axle is equipped with driving gear, the driven gear engagement of itself and last or bottom roller axle one end is with it to rotate, and the same end of upper and lower roller shaft also is equipped with pitch wheel makes two roller shafts relatively rotate.The bilateral transmission of double-motor: this type of drive is equal to the simple combination of two monolateral transmissions, the plate feeding device both sides drive the main driving axle on both sides respectively respectively with a motor via reducer, wheel chain mechanism, two main driving axles all are equipped with gear, by being with it to rotate with the driven gear engagement of last or bottom roller axle one end, pitch wheel all is equipped with at the two ends of upper and lower roller shaft makes both relatively rotate.
Cooresponding roller size of existing above-mentioned two kinds of type of drive and spacing find that in practice weak point is all arranged, patrilineal line of descent with only one son in each generation is moving can be because of the axle center in rotation process, can cause deflection, promptly less at the circumference of gear one side running orbit, opposite side is then bigger, will form certain degree of dip like this and cause the not steady of transmission plane, hardboard can not be subjected to very big the influence greatly because of its rigidity, but (thickness is between 0.018-1.0mm for soft board, long and wide between 100-610mm) just cannot, its suppleness is fine, but does not almost have rigidity, can not move on the roller of the sort of spacing, at first, because the driving axle center skew, soft board just can not move by pulsation-free in the above, can be offset along degree of dip.Secondly, the spacing and the spacing between the roller sheet in the roller axle center that patrilineal line of descent with only one son in each generation is moving are big, meeting board falling, roll bending, knuckle, clamp when plank is walked in the above.At last, because driving axle center both sides speed is inconsistent, also just will inevitably cause stressed inconsistently, will produce plank and pull power, cause the plank distortion, if this deflection will cause quality bad above certain scope, severe patient will cause scrapping.The mode of bilateral transmission can the monolateral driving axle center of balance beat, because all having, both sides beat, and this beating of having cancelled each other, but existing bilateral transmission is when transmitting soft board, because the resin in the middle of the soft board does not have rigidity, very soft, the staggered scope of the adjacent rollers of the roller spacing of existing this roller diameter and same roller shaft, adjacent rollers axle and roller shaft in the heart apart between the conveyer of design proportion on move, the phenomenon of knuckle, clamp still can appear.
The utility model content
The purpose of this utility model just provides and a kind ofly can effectively avoid the distortion of roller shaft and the deviation of two ends roller velocity of rotation, reduces axle head and beats, and the printed circuit board (PCB) wet process equipment plate feeding device of knuckle, clamp phenomenon can not occur when transmitting soft board.
For achieving the above object, the plate feeding device of this printed circuit board (PCB) wet process equipment, comprise driver train and the upper and lower roller shaft of roller is housed, it is characterized in that: described roller diameter D satisfies: 22≤D≤40mm, the roller spacing a of same roller shaft satisfies: 10≤a≤30mm, the staggered scope b of the adjacent rollers of adjacent rollers axle satisfies: 0＜b≤15mm, roller shaft satisfy 10≤L≤35mm apart from L in the heart.
On the basis of the above, basis is novel also can do further improvement:
Described driver train is the bilateral transmission of single motor: a motor that is arranged on the plate feeding device below, slow down by reductor, the output shaft of drop-gear box is the two ends outputs, two axial ends turns to by deflector, the deflector output shaft drives the main driving axle on both sides by the wheel link chain mechanism, main driving axle is equipped with driving gear, its rotation is with in the driven gear engagement of itself and last or bottom roller axle one end, on, the same end of bottom roller axle also is equipped with pitch wheel makes two roller shafts relatively rotate, and the friction force of roller shaft upper roller and pcb board is being carried pcb board up and down between live roller.
Described deflector is the crowngear deflector.
This later-model beneficial effect: adopt the bilateral transmission of single motor, can effectively avoid the distortion of roller shaft and the deviation of two ends roller velocity of rotation, reducing axle head beats, and adopted the staggered scope of adjacent rollers of roller spacing through the roller diameter of repeatedly practising and same roller shaft, adjacent rollers axle and roller shaft in the heart apart between design proportion, make knuckle, clamp phenomenon when the transmission soft board, not to occur.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the schematic top plan view of the utility model embodiment 1.
Fig. 2 is the driver train scheme drawing of the utility model embodiment 1.
Fig. 3 is the driver train scheme drawing of the utility model embodiment 2.
Among the figure: 1 motor, 2 drop-gear boxs, 3 driving gears, 4 main driving axles, 5 roller shafts, 6 roller shaft driven gears, 7 roller shaft engaging gears, 8 reduction gearbox output shafts, 9 deflectors, 10 sprocket wheels, 11 chains, 12 chain stretching devices.
The specific embodiment
Embodiment 1 illustrated in figures 1 and 2, this printed circuit board (PCB) wet process equipment plate feeding device, comprise the motor and the drop-gear box that are separately positioned on the plate feeding device both sides, drop-gear box exports the main driving axle that driving gear is installed to, its rotation is with in the driven gear engagement of driving gear and last or bottom roller axle one end, on, the same end of bottom roller axle also is equipped with pitch wheel makes both relatively rotate, wherein roller diameter D satisfies: 22≤D≤40mm, the roller spacing a of same roller shaft satisfies: 10≤a≤30mm, the staggered scope b of the adjacent rollers of adjacent rollers axle satisfies: 0＜b≤15mm, roller shaft satisfy 10≤L≤35mm apart from L in the heart.
The roller spacing of the driver train of plate feeding device and roller diameter that is adopted and same roller shaft in this printed circuit board (PCB) wet process equipment, staggered scope of the adjacent rollers of adjacent rollers axle and roller shaft be the design proportion between the distance in the heart, the flow process that is fit to soft board more, be staggered and allow soft board pulsation-free on roller move, can not fall into between the roller sheet because local pressure is big, prove that in this world staggered pattern in this scope is to allow the pulsation-free scope of soft board operation, limp is smooth and easy, the plate amount is little partially, fluctuation in the traveling process is very little, will advance as the pulsation-free on several hither planes, solve the inclined to one side plate when the flexible PCB plate wiring board that send thickness below 0.2mm of the plate feeding device in the existing installation effectively, flap, the problem that clamp is serious.
Embodiment of the present utility model 2 shown in Figure 3, only be to have adopted the bilateral transmission of single motor with the precedent difference, by a motor-driven, slow down by reductor, deceleration arbor two ends are equipped with deflector, drive the main driving axle on both sides again by the wheel link chain mechanism, and main driving axle is equipped with gear, drive the rotation of live roller axle up and down by gear meshing, the friction force of roller shaft upper roller sheet and pcb board is being carried pcb board up and down between live roller.
