Embodiment 1
[0036] figure 2 It is a structural schematic diagram of Embodiment 1 of the present invention; image 3 It is a side view of Embodiment 1 of the present invention; as figure 2 , image 3 As shown, the lead frame electroplating blanking device includes a substrate 6 . A front fixing plate 71 and a rear fixing plate 72 are installed on the lower surface of the base plate 6 , and a slit 73 is formed between the front fixing plate 71 and the rear fixing plate 72 . When blanking, the slit 73 is used for positioning the steel strip. The substrate 6 is provided with a through hole 61 .
[0037] A cylinder 1 is fixedly mounted on the upper surface of the substrate 6 , and the cylinder 1 has a reciprocating piston rod 101 , and a connecting fork 2 is mounted on the end of the piston rod 101 . Cylinder 1 acts as a reciprocating drive.
[0038] A boss 31 is arranged on the rotary lever 3 . The rotating lever 3 passes through the through hole 61 , the end 32 of the rotating lever...
Embodiment 2
[0045] Figure 5 It is a structural schematic diagram of Embodiment 2 of the present invention; Figure 6 It is a side view of Embodiment 2 of the present invention; as Figure 5 , Figure 6 As shown, the lead frame electroplating blanking device includes a substrate 6 . A front fixing plate 71 and a rear fixing plate 72 are installed below the base plate 6 , and a slit 73 is formed between the front fixing plate 71 and the rear fixing plate 72 . The substrate 6 is provided with a through hole 61 .
[0046] A cylinder 1 is fixedly mounted on the upper surface of the substrate 6 , and the cylinder 1 has a reciprocating piston rod 101 , and a connecting fork 2 is mounted on the end of the piston rod 101 . Cylinder 1 acts as a reciprocating drive.
[0047] The rotating lever 3 passes through the through hole 61 , the end 32 of the rotating lever 3 is located above the substrate 6 , and the end 33 is located below the substrate 6 . A rotating shaft 43 is installed at the thr...
Embodiment 3
[0052] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that there is no through hole 61 on the substrate 6 . The cylinder 1 , the piston rod 101 and the connection fork 2 are all arranged under the base plate 6 , and the rotary lever 3 is also located under the base plate 6 . All the other structures are the same as in Example 1.
[0053] The use principle of this embodiment is the same as that of Embodiment 1.

Abstract
The invention discloses an electroplating and blanking device for a lead frame, which is characterized by comprising a positioning device and a force applying device, wherein the positioning device is used for positioning a steel belt for clamping the lead frame, and the force applying device is used for applying force on a pinchcock for clamping the lead frame; after the positioning device positions the steel belt, the positions of the positioning device and the force applying device allow the force applying device to apply acting force on the pinchcock in the moving process; and the pinchcock is positioned on a moving path of the force applying device, and the force applying device pushes the pinchcock when moving, so that the pinchcock removes clamping force on the lead frame. The electroplating and blanking device for the lead frame can quickly remove the clamping force of the pinchcock on the lead frame, and has low labor intensity and high efficiency. The electroplating and blanking device can be matched with the traveling speed of the steel belt to be set to automatic blanking, so that the efficiency is higher. The risk of accidental injury is reduced. The invention can be suitable for needs of mass production.
Description
technical field [0001] The invention relates to a lead frame electroplating blanking device. Background technique [0002] Such as figure 1 As shown, when electroplating a lead frame, a plurality of lead frames 13 are suspended by steel strips 11 for electroplating. figure 1 Only one lead frame 13 is shown. A spring clip 12 is installed on the steel strip 11 , and the spring spring clip has a clip foot 121 , and the clip foot 121 has a section 122 parallel to the steel strip 11 . The clamping foot 121 of the spring clip 12 passes through the steel strip 11 , and the part 122 parallel to the steel strip 11 and the steel strip 11 clamp the lead frame 13 by the elastic force of the spring clip 12 . During the electroplating process, the spring clip 12 fixes the lead frame 13 on the steel strip 11 and moves with the steel strip 11; after the electroplating is completed, the lead frame 13 needs to be separated from the steel strip. The blanking process is as Figure 4 As sho...
