Background technology
The operation principle of feeding machine with rolling wheel structure is the end face that is compressed material by top roller, and the feeding roller below the driving mechanism transmission is in the push feed of the back side of material.In IC punching formation equipment, the integrated circuit overwhelming majority is arranged on the lead frame, be the key of whole feed mechanism and how can accurately lead frame be transported in the middle of the mould rapidly and when abnormal conditions occur, can handle problems fast, at present common feeding style is that form by the material toggling pin transmits, but this mode has two drawbacks: 1. need to design corresponding mechanism and break away from the band correcting action and prepare feeding again at this insertion band, and so forth; 2. dialling pin damages band under specific circumstances easily and be not easy processing when appearance is unusual.
The utility model content
The technical problems to be solved in the utility model is the feed mechanism complex operation in the existing integrated circuits punching formation equipment, occurs being difficult for when unusual handling, and a kind of simple to operation, feeding machine with rolling wheel structure fast and accurately is provided for this reason.
The technical solution of the utility model is: the feeding machine with rolling wheel structure that is used for IC punching formation equipment, it comprises base and the transporting rail that is used for transmitting lead frame that is positioned on the base, described base near transporting rail one end is provided with the lead frame flattening mechanism, is provided with the driving mechanism of roller hold-down mechanism and driving rolls hold-down mechanism in the transporting rail.
Lead frame flattening mechanism in the such scheme comprise by motor-driven some upper roll wheels and with the opposed lower roll wheel of upper roll wheel each interval.
Roller hold-down mechanism in the such scheme comprises lever, pillar with the flexible connection of lever one end, the last contact roller of fixedlying connected with the lever other end and the following contact roller that is in transmission connection with driving mechanism, loosen cylinder near being connected with the roller that normality is in contraction state on the lever of pillar one side, the fulcrum of described lever loosens between cylinder and the last contact roller at roller, be provided with the spring that is in compressive state between described pillar inside and the base and make lever provide downward pressure and following contact roller to compress for contact roller, when roller loosens cylinder and loosens, to the downward pressure of lever the last contact roller that is positioned at the balance pivot opposite side is upwards lifted.
Driving mechanism in the such scheme comprises the rotating shaft that flexibly connects with following contact roller, and described rotating shaft is connected with decelerator by shaft coupling, and described decelerator is connected with servomotor.
Transporting rail in the such scheme is provided with adjusting screw(rod) and makes the width-adjustable of transporting rail.
The beneficial effects of the utility model are that lead frame process lead frame flattening mechanism leveling earlier is delivered to the roller hold-down mechanism that is driven by driving mechanism by transporting rail again, and whole process need not the people and operates by hand, and is quick and convenient accurate, high efficiency.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises base 15 and the transporting rail 6 that is used for transmitting lead frame that is positioned on the base, described base near transporting rail one end is provided with lead frame flattening mechanism 5, is provided with the driving mechanism of roller hold-down mechanism and driving rolls hold-down mechanism in the transporting rail.
The lead frame flattening mechanism can be by motor-driven some upper roll wheels 13 and with the opposed lower roll wheel 14 of upper roll wheel each interval.Leave the gap that can supply lead frame to pass through between upper roll wheel and the lower roller shaft, the quantity of upper roll wheel and lower roll wheel without limits, in order to reach better leveling effect, the quantity of upper roll wheel and lower roll wheel is The more the better, for example can be 2 upper roll wheels and 3 lower roll wheels, perhaps 3 upper roll wheels and 4 lower roll wheels, or the combination of other arbitrary number, last roll shaft and lower roller shaft can be fixed on the base by mount pad.
The roller hold-down mechanism comprises contact roller 10 and following contact roller 11, go up between contact roller and the following contact roller under the normality and compress mutually, be connected with lever 8 on the last contact roller, the fulcrum of lever is located at the lever middle part, the other end of lever is connected with pillar 9, the pillar below links to each other with base 15 by spring, the normality lower spring is in impaction state, can give the reaction force that makes progress of lever that is movably connected on the pillar like this, thereby make be positioned at last a contact roller downward pressure of acquisition of balance pivot opposite side so that compress through lead frame, for the ease of adjusting the degree that compresses between contact roller and the following contact roller, can loosen cylinder 7 being connected with the roller that normality is in contraction state near the lever of pillar one side, this roller loosens cylinder between the fulcrum of lever and pillar and is in contraction state under the normality, when in the needs adjustment during contact roller roller loosen cylinder and loosen to press down and offset the reaction force that the pillar lower spring is given lever, make that going up contact roller can abovely lift and break away from contact roller down.
Driving mechanism comprises the rotating shaft 4 that flexibly connects with following contact roller, and rotating shaft is connected with decelerator 2 by shaft coupling 3, and described decelerator is connected with servomotor 1, makes servomotor can drive down contact roller and rotate that following contact roller and then drive are gone up contact roller and rotated.
In order to adapt to the needs of different in width lead frame, can be provided with the width that adjusting screw(rod) 12 can adjustable track and then satisfy the feeding demand of different in width lead frame at transporting rail.
The utility model use is as follows: lead frame is at first sent into the lead frame flattening mechanism, enter transporting rail after the leveling through upper roll wheel and lower roll wheel, the horizontal plane of the last contact roller of the roller hold-down mechanism in the transporting rail and the contact of following contact roller and upper roll wheel and the slit between the lower roll wheel of lead frame flattening mechanism are in the same horizontal plane, driving mechanism drives down, and contact roller rotates, go up contact roller and rotate push feed thereby following contact roller drives, contact roller under making during contact roller roller loosen that cylinder is in retracted mode in the needs adjustment and then by lever principle contact roller being raised to break away from.
