Description
Technical field
The utility model relates to a kind of driving mechanism, especially relates to a kind of driving mechanism that is used for printed circuit board (PCB) (PCB) wet process equipment plate feeding device.
Background technique
The mode of plate feeding device is in printed circuit board (PCB) (PCB) wet process: 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 roller.
The driving mechanism of existing plate feeding device mainly contains following three kinds of modes:
Monolateral transmission.Refer to drive a main drive shaft with a motor via reducer, sprocket chain bar, main drive shaft 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 both relatively rotate.This driving mode has following inevitable defective: because the roller shaft size generally all is about 10mm, and length is generally more than 700mm, the non-stress end of roller shaft have only a termination to receive moment of torsion, so can produce irregular jumping phenomena (referring to Fig. 1).This jumping phenomena can produce two kinds of bad phenomenon: the roller transmission speed at roller shaft two ends can produce difference, the conveying of pcb board between live roller can produce by the phenomenon of non-stress end to the force side skew so, if this side-play amount is excessive, pcb board can produce the reaction non-uniform phenomenon, quality for pcb board causes very big influence, and serious will cause scrapping of pcb board; In addition, because the roller two ends are equipped with fixed block, the jumping phenomena of non-stress end can make the two ends unbalance stress, long-time use can cause the roller shaft distortion, cause pcb board between roller, to produce inclined to one side plate, flap, clamp, cause quality bad, cause sometimes that pcb board is large batch of to be scrapped.
The bilateral transmission of dual-motor: this kind of drive is equal to the simple combination of two monolateral transmissions.Both sides drive the main drive shaft on both sides respectively respectively with a motor via reducer, chain mechanism, two main drive shafts 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.Two motors carry out the adjusting of speed respectively with frequency variator, reach the conformity of two ends speed according to this.Theoretically, this driving mechanism is the conformity that can reach two ends speed, but because the otherness of electric machine structure, and the error of frequency variator existence, in fact can not reach this effect, two ends still can produce no small speed variation, and this is verified in the application of reality.In fact inconsistent because of adjacent two shaft speed, still can cause pcb board in production is advanced, to produce and pull phenomenon, cause phenomenons such as plate distortion, inclined to one side plate, cause quality bad.
The bilateral transmission of single motor Single Side: this kind of drive is meant with a motor in a side drive, the main drive shaft by speed reducer, commutator, chain mechanism drive both sides on an axle.This driving mechanism has overcome the otherness of electric machine structure in the two transmissions of dual-motor and the defective of frequency variator error, but because motor is installed in a side of transmission, the transmission situation of major axis can produce jumping phenomena as shown in Figure 1 equally on the speed reducer.Because the jumping phenomena of axle on the speed reducer, can produce deviation by commutator, chain mechanism driving equally to the speed on the transmission shaft on both sides, thereby cause live roller two ends velocity deviation, still can produce the phenomenon of inclined to one side plate, flap, clamp, cause quality bad.
The model utility content
The purpose of this utility model just provides a kind of driving mechanism that is used for printed circuit board (PCB) wet process equipment plate feeding device, and it has avoided the distortion of roller shaft and the deviation of two ends roller rotational velocity effectively, and axle head is beated and also reduced greatly.
For achieving the above object, the driving mechanism that is used for printed circuit board (PCB) wet process equipment plate feeding device of the present utility model, comprise motor and speed reducer, speed reducer exports the main drive shaft 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, it is characterized in that: described motor and speed reducer are installed in the centre of plate feeding device, the output shaft of speed reducer is the two ends outputs, two axial ends turns to by commutator, sprocket wheel is housed on commutator output shaft and the main drive shaft and passes through the chain transferring power.
On the basis of the above, the utility model also can be done further improvement:
Described commutator is the bevel gear commutator.
On the described sprocket wheel link chain mechanism chain stretching device is housed.
The beneficial effects of the utility model: because motor and speed reducer are installed in the centre of plate feeding device, the output shaft of speed reducer is the two ends outputs, the force part of deceleration arbor is in the centre, the monolateral length of output shaft just is equivalent to half of the bilateral transmission of above-mentioned single motor like this, beating of deceleration arbor non-stress end will reduce greatly like this, and the stressing conditions on deceleration arbor both sides is identical with transmission speed, the power that is transported on the live roller is also just consistent with speed, reduced the inclined to one side plate phenomenon that causes owing to transmission speed is inconsistent greatly, and the two ends of roller shaft are stressed about the same, effectively avoided the distortion situation of axle, the inclined to one side plate that produces owing to shaft distortion, flap, bad phenomenon such as clamp also greatly reduce, and manufacture the transmission capacity guarantee that provides strong for pcb board.
