The lead frames are firstly leveled by the lead frame leveling mechanism and then are transmitted to the idler pressing mechanism driven by the driving mechanism through the transmission rail, the whole process does not need to be operated manually, and therefore the idler wheel feeding mechanism for the integrated circuit punching and molding device has the advantages of being fast, convenient and accurate, and high in working efficiency.
Description
Technical field
The present invention relates to roller feeding mechanism, particularly relate to the roller feeding mechanism for IC punching formation equipment.
Background technology
The operation principle of roller feeding mechanism is by the end face of roller compression material above, by the back side push feed of the material-feeding rolling wheels below driving mechanism transmission at material.In IC punching formation equipment, the integrated circuit overwhelming majority arranges on the lead frames, and how accurately lead frame to be transported to rapidly in the middle of mould and the key that problem is whole feed mechanism can be processed when abnormal conditions occur fast, feeding style common is at present transmitted by the form of material toggling pin, but this mode has two drawbacks: 1. need to design corresponding mechanism and prepare feeding again to depart from band correcting action and to insert band at this, and so forth; 2. pulling needle is easily damaged band under specific circumstances and is not easy process when occurring abnormal.
Summary of the invention
The technical problem to be solved in the present invention is the feed mechanism complex operation in existing IC punching formation equipment, not easily processes when occurring abnormal, provides a kind of simple to operation, roller feeding mechanism fast and accurately for this reason.
Technical scheme of the present invention is: for the roller feeding mechanism of IC punching formation equipment, it comprises base and is positioned at the transporting rail for transmitting lead frame on base, the described base near transporting rail one end is provided with lead frame flattening mechanism, is provided with the driving mechanism of roller compression mechanism and driving rolls hold-down mechanism in transporting rail.
Lead frame flattening mechanism in such scheme comprises by motor-driven some upper roll wheels and is spaced opposed lower roll wheel with upper roll wheel.
Roller compression mechanism in such scheme comprises lever, the pillar be flexibly connected with lever one end, the upper contact roller be fixedly connected with the lever other end and the lower contact roller be in transmission connection with driving mechanism, on the lever of pillar side, be connected with the roller that normality is in contraction state loosen cylinder, the fulcrum of described lever loosens between cylinder and upper contact roller at roller, being provided with the spring being in compressive state between described pillar inside and base makes lever provide downward pressure and lower contact roller to compress to contact roller, to the pressure that lever is downward, the upper contact roller being positioned at balance pivot opposite side is upwards lifted when roller loosens when cylinder loosens.
Driving mechanism in such scheme comprises the rotating shaft be flexibly connected with lower contact roller, and described rotating shaft is connected with decelerator by shaft coupling, and described decelerator is connected with servomotor.
Transporting rail in such scheme is provided with the width-adjustable that adjusting screw(rod) makes transporting rail.
The invention has the beneficial effects as follows that lead frame is first delivered to by transporting rail the roller compression mechanism driven by driving mechanism again through the leveling of lead frame flattening mechanism, whole process is without the need to people's manual operations, and accurately quick and convenient, operating efficiency is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the transporting rail 6 for transmitting lead frame that the present invention includes base 15 and be positioned on base, the described base near transporting rail one end is provided with lead frame flattening mechanism 5, is provided with the driving mechanism of roller compression mechanism and driving rolls hold-down mechanism in transporting rail.
Lead frame flattening mechanism can be by motor-driven some upper roll wheels 13 and be spaced opposed lower roll wheel 14 with upper roll wheel.The gap can passed through for lead frame is left between upper roll wheel and lower roller shaft, the quantity of upper roll wheel and lower roll wheel does not limit, better effect is flattened in order to reach, the quantity of upper roll wheel and lower roll wheel is The more the better, can be such as 2 upper roll wheels and 3 lower roll wheels, or 3 upper roll wheels and 4 lower roll wheels, or the combination of other arbitrary number, upper roll shaft and lower roller shaft can be fixed on base by mount pad.
Roller compression mechanism comprises contact roller 10 and lower contact roller 11, above mutually compress between contact roller and lower contact roller under normality, upper contact roller is connected with lever 8, the fulcrum of lever is located at its intermediate part, the other end of lever is connected with pillar 9, be connected with base 15 by spring below pillar, normality lower spring is in impaction state, like this can to one, the lever be movably connected on pillar reaction force upwards, thus make the upper contact roller being positioned at balance pivot opposite side obtain a downward pressure and then compress the lead frame of process, for the ease of adjusting the compression degree between upper contact roller and lower contact roller, the roller that normality is in contraction state can be connected with loosen cylinder 7 on the lever near pillar side, this roller loosens cylinder between the fulcrum and pillar of lever and is in contraction state under normality, when needing adjustment upper contact roller, roller loosens cylinder and loosens to press down and counteract pillar lower spring to the reaction force of lever, contact roller can be lifted above and depart from lower contact roller.
Driving mechanism comprises the rotating shaft 4 be flexibly connected with lower contact roller, and rotating shaft is connected with decelerator 2 by shaft coupling 3, and described decelerator is connected with servomotor 1, makes servomotor that lower contact roller can be driven to rotate, and lower contact roller and then the upper contact roller of drive rotate.
In order to adapt to the needs of different in width lead frame, can be provided with on transporting rail adjusting screw(rod) 12 can adjustable track width so that meet the feeding demand of different in width lead frame.
Use procedure of the present invention is as follows: first lead frame sends into lead frame flattening mechanism, transporting rail is entered after the leveling of upper roll wheel and lower roll wheel, the horizontal plane of the upper contact roller of the roller compression mechanism in transporting rail and the contact of lower contact roller and the gap between the upper roll wheel of lead frame flattening mechanism and lower roll wheel are in same level, driving mechanism drives lower contact roller to rotate, lower contact roller drives upper contact roller to rotate thus push feed, make roller loosen cylinder to be in retracted mode when the upper contact roller of needs adjustment and then to make upper contact roller raise the lower contact roller of disengaging by lever principle.
