Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. Material feeding unit for triode trimmer, constitute as shown in figure 1, including lift seat 1, be connected with lift portion 2 and guide bar 3 on the lift seat 1 respectively, one side of lift seat 1 is equipped with the pay-off mouth 4 of U-shaped, the opening direction of pay-off mouth 4 is vertical downwards, can dismantle on the lift seat 1 all around of pay-off mouth 4 and be connected with installation piece 5, be equipped with a plurality of mounting grooves 6 on the installation piece 5 side by side, equal lock is connected with the backup pad 7 that is located pay-off mouth 4 on every mounting groove 6, backup pad 7 symmetry sets up the left and right sides at pay-off mouth 4, the mounting groove 6 at lift seat 1 front and back both ends is connected respectively at the both ends of backup pad 7, one side of pay-off mouth 4 is equipped with flitch 8, the width of flitch 8 is less than the interval between the backup pad 7 of both sides, the external connection of flitch 8 has the driving piece, this driving piece can select for use the cylinder.
The wire guide frame is characterized by further comprising a conveying wheel 9 positioned on the shaping machine, a rubber layer is coated on the surface of the conveying wheel 9, the lower end of the conveying wheel 9 is attached to the wire guide frame, and a rotating motor is connected to the outside of the conveying wheel 9; the shaping machine comprises a shaping frame 100, wherein the top of the shaping frame 100 is detachably connected with a pressing plate 200, a placing cavity for accommodating a lead frame is formed between the pressing plate 200 and the shaping frame 100, the lower end of a conveying wheel 9 penetrates through the pressing plate 200 and extends into the placing cavity, an opening is formed in one side of the placing cavity, and a shaping plate 300 which is rotatably connected with the shaping frame 100 is arranged in the opening; when the chip carrier shaping device is used, one side of a pin of the lead frame is positioned in the placing cavity, one side of a chip carrier of the lead frame is positioned in the opening, and the shaping plate 300 extrudes and bends the chip carrier in the opening after rotating, so that the chip carrier forms a uniform bending angle after being extruded, and the shaping effect is achieved.
