specific Embodiment approach

[0052] Specific implementation method: combined Figure 1 to Figure 15 Further explain the working principle of this application.

[0053] The discharge method of the storage mechanism 200 is to first place the frame tray 300 with the lead frame 1 stacked in the rectangular space formed by the angle steel 210 before the work, so that the card slot 303 is matched with the card bar 211, and the support seat 220 is facing to the middle. protruding, the bottom surface of the rectangular slot 301 is supported by the top surface of the support block 222 . When discharging, the lifting block 410 rises up to the set height, so that the rib 302 is inserted into the strip groove 411, and then the support seat 220 is retracted to both sides, and the lifting block 410 fully supports the frame tray 300 at this time; The lifting block 410 moves downward to set the height. At this time, the bottom frame tray 300 is in contact with the top surface of the transport tray 130, and the rib 302 i...

Abstract

The invention provides a feeding device for lead frame assembly. The device comprises: a conveying mechanism, which comprises a pair of conveying rails and a driving apparatus, wherein the driving apparatus is provided with a conveying disc in a sliding mode, the top of the conveying disc is provided with a plurality of parallel limiting grooves, and the top face of the rear section of each conveying rail is provided with a heightening strip; a storage mechanism, which is arranged at the front end of the conveying mechanism and used for stacking the frame trays upwards, wherein angle steel is located above the conveying rails, a gap is reserved between the bottom face of the angle steel and the conveying face of the conveying rails, the storage mechanism further comprises a pair of supporting seats, and at least two supporting blocks are arranged on the side wall, facing the middle of the conveying mechanism, of each side baffle, upper inclined surfaces are arranged above the front ends of the supporting blocks, the bottoms of the frame trays are provided with rectangular grooves corresponding to the supporting blocks and provided with ribs corresponding to the limiting grooves, and the ribs are in clearance fit in the limiting grooves; and a lifting mechanism, which comprises a pair of lifting blocks that move up and down in the vertical direction. The frame trays can be automatically output, labor is saved, and production efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the lead frame assembly technology in the field of semiconductor packaging, in particular to a material feeding device for lead frame assembly. Background technique [0002] The existing assembly device for multi-layer structure lead frame places multiple lead frames of a product on the same frame tray according to a certain position sequence, and then takes materials and assembles them. The existing production method manually assembles the lead frames The frame tray with multiple lead frames is placed on the conveyor line of the assembly equipment, and then the frame tray is driven by the conveyor line to move to different stations for grabbing and assembly. This method requires long-term arrangements for operators to place frame trays at the loading position of the device, which takes up a lot of labor, and the degree of automation of the device is low, which affects production efficiency. Contents of the invention [0003...
