DETAILED DESCRIPTION
[0026] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 3 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.
[0027] Figure 1 It is a structural diagram of an embodiment of a lead frame stamping and feeding device of the utility model; Figure 2 1 is a cross-sectional view of an adjusting member of a lead frame of a preferred embodiment of the present invention. Figure 1 and Figure 2 As shown, the lead frame stamping feeding device provided in this embodiment is arranged at the feed port of the stamping machine and is located between the external material rack and the stamping die, and the metal strip roll is placed on the material rack, and one end of the metal strip 4 of the metal strip roll is pulled through the lead frame stamping feeding device provided in this embodiment and then enters the stamping die, ensuring that the metal strip 4 will be cleaned by the lead frame stamping feeding device provided in this embodiment before stamping, thereby ensuring the quality of the processed lead frame. At this time, the lead frame stamping feeding device provided in this embodiment includes: a mounting frame 1, a support frame 2, and a decontamination component 3.
[0028] Specifically, one end of the mounting frame 1 is fixedly mounted at the feed port of the punching machine. At this time, a plurality of connection holes are provided on the frame at the feed port of the punching machine, and a plurality of assembly holes corresponding to the connection holes are provided on one end of the mounting frame 1 fixed to the punching machine, and the assembly holes and the connection holes are fixedly connected by bolts, thereby realizing the stable installation of the mounting frame 1 at the feed port of the punching machine. In addition, the other end of the mounting frame 1 is extended along the feed direction of the feed port, which facilitates the subsequent installation of the decontamination component 3 on the conveying path of the metal strip 4.
[0029] Specifically, two support frames 2 are provided. During installation, both support frames 2 are installed on the mounting frame 1, so that the support frame 2 is installed at the feed port of the punching machine. Moreover, the two support frames 2 are symmetrically arranged on both sides of the feed direction, so that there is a gap between the two support frames 2, which provides installation and working space for the subsequent installation of the dirt removal component 3. At the same time, it also provides conditions for both ends of the subsequent dirt removal component 3 to be supported to improve the installation stability.
[0030] Specifically, the decontamination assembly 3 is arranged between the two support frames 2. At this time, the decontamination assembly 3 includes an upper pressing plate 31, a lower pressing plate 32 and a decontamination strip 33. During installation, both ends of the upper pressing plate 31 and the lower pressing plate 32 are installed on the support frame 2, so that the upper pressing plate 31 and the lower pressing plate 32 are stably installed. At the same time, the upper pressing plate 31 and the lower pressing plate 32 are stacked up and down and placed horizontally in the feeding direction, so that the upper pressing plate 31 and the lower pressing plate 32 can form a clamping structure, which provides conditions for the subsequent arrangement of the decontamination strip 33 between the upper pressing plate 31 and the lower pressing plate 32 to clamp. In addition, decontamination strips 33 are installed on the opposite surfaces of the upper pressing plate 31 and the lower pressing plate 32. Pressure is applied to the two decontamination strips 33 through the upper pressing plate 31 and the lower pressing plate 32. At this time, the metal strip 4 to be processed passes between the two decontamination strips 33 and enters into the stamping die. The decontamination strips 33 contact the surface of the passing metal strip 4, thereby removing impurities such as oil and dust on the metal strip 4, thereby avoiding the impurities on the metal strip 4 affecting the stamping operation of the stamping die, thereby ensuring the processing quality of the lead frame. It is worth pointing out that a feeding assembly is provided at the feed port of the punching machine, and the feeding assembly includes a mounting seat, an upper pressure roller and a lower pressure roller. The mounting seat is installed on the frame at the feed port of the punching machine, and the upper pressure roller and the lower pressure roller are both rotatably installed on the mounting seat. At the same time, the upper pressure roller and the lower pressure roller are arranged in parallel in the state of upper and lower layers, and the axial directions of the upper pressure roller and the lower pressure roller are perpendicular to the feeding direction, so that all the rotation directions of the upper pressure roller and the lower pressure roller are arranged along the feeding direction. At this time, the upper pressure roller or the lower pressure roller is connected to a rotary drive to realize the rotation of the upper pressure roller and the lower pressure roller. When feeding, the metal strip 4 passes through between the upper pressure roller and the lower pressure roller and is pressed by the upper pressure roller and the lower pressure roller. The rotation of the upper pressure roller or the lower pressure roller pulls the metal strip 4 to move in the feeding direction, thereby realizing the feeding operation.
[0031] More specifically, the dirt removal strip 33 is made of wool felt, which can be purchased and used directly, and has good flexibility. It will not scratch the metal strip 4 when removing impurities such as oil, dust, etc., further ensuring the quality of the processed lead frame.
[0032] More specifically, both ends of the upper pressing plate 31 and the lower pressing plate 32 are provided with adjusting members 34, and the two adjusting members 34 are respectively mounted on the two support frames 2, that is, both ends of the upper pressing plate 31 and the lower pressing plate 32 are mounted on the support frame 2 through the adjusting members 34, so that the adjusting members 34 serve as the intermediate structure for the upper pressing plate 31 and the lower pressing plate 32 to be mounted on the support frame 2. In addition, both adjusting members 34 deflect in a plane perpendicular to the upper pressing plate 31 and the lower pressing plate 32, so that the upper pressing plate 31 and the lower pressing plate 32 can achieve an angle flip. As the metal strip 4 is continuously used, the diameter of the metal strip coil gradually decreases, resulting in a change in the height of the metal strip 4 when it is drawn out from the metal strip coil. In addition, since the height of the feed port of the punching machine cannot be adjusted, the angle of the metal strip 4 relative to the feed port of the punching machine will change. If the angle of the upper pressure plate 31 and the lower pressure plate 32 cannot be adjusted, the resistance caused by the metal strip 4 when passing through the gap between the upper pressure plate 31 and the lower pressure plate 32 will increase, and the upper pressure plate 31 and the lower pressure plate 32 can achieve angular deflection through the adjustment part 34, thereby adapting to the change in the feeding angle of the metal strip 4, and always maintaining the upper pressure plate 31 and the lower pressure plate 32 parallel to the strip surface of the metal strip 4, so as to facilitate the feeding of the metal strip 4.
[0033] More specifically, the support frame 2 for installing the adjustment member 34 includes a vertical pole 21 and a sleeve block 22. At this time, the vertical pole 21 is arranged vertically upward, and the lower end of the vertical pole 21 is fixedly installed on the mounting frame 1. Preferably, the lower end of the vertical pole 21 is welded to the mounting frame 1. At the same time, the sleeve block 22 is sleeved on the corresponding vertical pole 21 and temporarily fixed on the corresponding vertical pole 21. When the height of the sleeve block 22 needs to change, it can be achieved by sliding the sleeve block 22 on the vertical pole 21. When the sleeve block 22 needs to maintain stability, the sleeve block 22 can be temporarily fixed on the vertical pole 21, thereby meeting the feeding of metal strips 4 of different specifications and sizes, and the structure is more flexible.
[0034] More specifically, a locking screw 23 is further provided between the sleeve block 22 and the corresponding vertical pole 21. At this time, a penetrating locking hole is opened on the sleeve block 22, and the locking hole is a threaded hole. At the same time, a threaded end of a locking screw 23 is inserted into the locking hole and threadedly connected, and the threaded end of the locking screw 23 is against the vertical pole 21. When the locking screw 23 is loosened, the sleeve block 22 can slide on the corresponding vertical pole 21 to adjust the height of the sleeve block 22. When the locking screw 23 is tightened, the sleeve block 22 is temporarily fixed on the corresponding vertical pole 21 to maintain the stability of the position of the sleeve block 22.
[0035] More specifically, the adjusting member 34 disposed between the support frame 2 and the upper pressing plate 31 and the lower pressing plate 32 further includes a connecting sleeve 341, a bearing 342 and a fork frame 343. During installation, the connecting sleeve 341 is arranged horizontally and one end of the connecting sleeve 341 is fixed to the sleeve block 22 of the support frame 2 on the corresponding side. Preferably, the connecting sleeve 341 and the sleeve block 22 are welded. In addition, the bearing 342 is arranged in the connecting sleeve 341 and the outer ring is fixed on the connecting sleeve 341, so that the bearing 342 is stably installed on the connecting sleeve 341. In addition, the fork frame 343 is arranged in a "Y" shape, so that the fork frame 343 has an independent end and a fork end. During installation, the independent end of the fork frame 343 is inserted into the bearing 342, and the independent end of the fork frame 343 is inserted into the inner ring of the bearing 342 and fixed on the inner ring of the bearing 342, so that the fork frame 343 can be stably installed on the support frame 2 and can rotate on the support frame 2. In addition, the forked end of the fork frame 343 is arranged toward the other support frame 2, so that the forked ends of the two fork frames 343 can be arranged relative to each other, providing installation space for the subsequent installation of the upper pressing plate 31 and the lower pressing plate 32. During installation, the same end of the upper pressure plate 31 and the lower pressure plate 32 are both arranged in the fork end of the same fork frame 343, and the same end of the upper pressure plate 31 and the lower pressure plate 32 are respectively installed on the two fork arms 3431 at the fork end, thereby realizing the installation requirement that the same end of the upper pressure plate 31 and the lower pressure plate 32 are installed on the same fork frame 343, so that the upper pressure plate 31 and the lower pressure plate 32 can rotate relative to the support frame 2 through the fork frame 343, the bearing 342, and the connecting sleeve 341, thereby realizing the adjustment of the angle of the upper pressure plate 31 and the lower pressure plate 32, and at the same time, it also ensures that the rotation of the upper pressure plate 31 and the lower pressure plate 32 can maintain a synchronous state, ensuring that the upper pressure plate 31 and the lower pressure plate 32 can always maintain a relatively parallel state, thereby facilitating the passage of the metal belt 4.
[0036] More specifically, the two ends of the lower pressing plate 32 are fixedly mounted on the fork arms 3431 corresponding to the two fork frames 343. Preferably, connecting screws are provided between the lower pressing plate 32 and the fork arms 3431 of the two fork frames 343, and the two ends of the lower pressing plate 32 are fixed to the fork arms 3431 of the two fork frames 343 by the connecting screws. At the same time, adjusting rods 311 are provided between the two ends of the upper pressing plate 31 and the corresponding fork arms 3431 on the two fork frames 343, and the adjusting rods 311 serve as the connecting structure between the upper pressing plate 31 and the fork arms 3431 of the two fork frames 343. At this time, the fork arms 3431 corresponding to the upper pressing plate 31 are provided with adjustment holes 312. During installation, one end of the adjustment rod 311 is fixed to the side of the upper pressing plate 31 away from the lower pressing plate 32. Preferably, the adjustment rod 311 and the upper pressing plate 31 are welded so that the adjustment rod 311 and the upper pressing plate 31 can form an integral structure, which provides conditions for the subsequent adjustment rod 311 to guide the upper pressing plate 31. In addition, the other end of the adjustment rod 311 is passed through the adjustment hole 312 on the corresponding fork arm 3431, and the adjustment rod 311 can slide along its axial direction in the corresponding adjustment hole 312, thereby realizing the position adjustment of the upper pressing plate 31 relative to the fork arm 3431, so that the spacing between the upper pressing plate 31 and the lower pressing plate 32 can change, thereby adapting to the passage of metal strips 4 of different thicknesses. In addition, a clamping spring 313 is sleeved on each adjusting rod 311, and the two ends of the clamping spring 313 are respectively pressed against the upper pressure plate 31 and the corresponding fork arm 3431, that is, the clamping spring 313 provides the upper pressure plate 31 with a thrust to move toward the lower pressure plate 32, so that the upper pressure plate 31 approaches the lower pressure plate 32, thereby clamping the two decontamination strips 33 to clean the impurities on the metal belt 4.
[0037] More specifically, the end of each adjusting rod 311 away from the end connected to the upper pressure plate 31 is a threaded head structure, and a limiting nut 314 is installed on each threaded head structure. That is, after the adjusting rod 311 is inserted into the corresponding adjusting hole 312, the limiting nut 314 is installed on the threaded head. The limiting nut 314 forms a limiting structure at the end of the adjusting rod 311, which prevents the adjusting rod 311 from escaping from the adjusting hole 312, thereby providing higher safety.
[0038] More specifically, a guide sleeve 315 is also provided on each fork arm 3431 with an adjustment hole 312. At this time, the guide sleeve 315 is coaxially arranged with the corresponding adjustment hole 312 and the adjustment rod 311, and one end of the guide sleeve 315 is fixedly connected to the corresponding fork arm 3431. Preferably, the guide sleeve 315 and the corresponding fork arm 3431 are also welded. The axial length of the adjustment hole 312 is extended by the guide sleeve 315, so that when the adjustment rod 311 slides relative to the adjustment hole 312, the guide sleeve 315 and the adjustment hole 312 can jointly guide the adjustment rod 311, thereby further improving the stability of the adjustment rod 311 when moving.
[0039] Figure 3 This is a cross-sectional view of the installation of the upper pressing plate and the decontamination strip of a preferred embodiment of the utility model. Figure 1 and Figure 3 As shown, a plurality of protruding limiting teeth 316 are provided on the side surfaces opposite to each other of the upper pressure plate 31 and the lower pressure plate 32. When the two decontamination strips 33 are subsequently installed between the upper pressure plate 31 and the lower pressure plate 32, the opposite sides of the two decontamination strips 33 can respectively abut against the limiting teeth 316 on the upper pressure plate 31 and the lower pressure plate 32, thereby avoiding the problem of dragging the decontamination strip 33 when the metal belt 4 passes through the gap between the two decontamination strips 33, ensuring the stability of the decontamination strip 33 after installation and ensuring the decontamination effect.
