the protection component (5) and the lead frame transferring component (8) are sequentially arranged along the moving direction of the conveying belt (2), so that the jig plate (11) sequentially passes through the protection component (5) and the lead frame transferring component (8) under the action of the conveying belt (2), the lead frame transferring component (8) is used for transferring the welded lead frame (10) to the collecting tray, the second positioning component (7) and the fifth air cylinder are arranged on the underframe (1) and correspond to the position of the lead frame transferring component (8), the positioning component (7) is used for stopping the jig plate (11) under the lead frame transferring component (8), and the fifth air cylinder is used for separating the jig plate (11) from the shelving component (9).
9. The integrated coil soldering point device according to claim 8, wherein the lead frame transfer unit (8) comprises a frame (801), an electric screw (802) mounted on the frame (801), a transfer frame (803) is mounted on a moving seat of the electric screw (802), a plurality of hooks (805) are uniformly and movably mounted on the transfer frame (803) through a plurality of electric cylinders (804), and the electric cylinders (804) can hook up the lead frame (10) in cooperation with the hooks (805), so that the position of the lead frame (10) is transferred.
10. A method of operation using an integrally formed coil solder joint arrangement as claimed in claim 8, comprising the steps of:
s1, firstly, placing a lead frame (10) and a coil on a jig plate (11) according to corresponding positions;
s2, then the placing component (9) is driven by the conveying belt (2) to drive the jig plate (11) to move along the direction of the conveying belt (2), so that when the lead frame (10) and the coil reach the position right below the welding component (4) under the driving of the jig plate (11), the jig plate (11) stops right below the welding component (4) under the positioning action of the positioning component (7), and simultaneously the welding component (4) welds the lead frame (10) and the coil together under the protection of the protection component (5);
s3, after the welding operation is finished, the jig plate (11) falls onto the conveyor belt (2), the welded lead frame (10) and the coil move along with the conveyor belt (2) by a transverse distance, namely, the row distance of the hollowed-out structure (504), and then are lifted up by the protection component (5), and the coil and the lead frame (10) form a molten ball shape when being welded by laser, and the molten ball is not solidified at the moment, so that the bulge of the welding spot position can be flattened under the action of the protection component (5);
s4, after the flattening operation is completed, the jig plate (11) moves to the position right below the lead frame transfer assembly (8) along with the conveyor belt (2);
s5, stopping the jig plate (11) under the lead frame transferring assembly (8) by the positioning assembly (7), separating the jig plate (11) from the placing assembly (9) by the air cylinder five, transferring the lead frame (10) by the lead frame transferring assembly (8), and transferring the welded lead frame (10) to the next compression molding process.
