Embodiment 1

[0021] The structure of this embodiment, such as figure 1 As shown, a lead frame paper tape recovery and cleaning equipment includes a box body 1, a support device 4 is fixed on the bottom wall of the box body 1, and a winding device 2 and a cleaning device 2 are fixed on the front wall of the box body 1 from top to bottom. device 3 , the winding device 2 is connected with a driving device 5 arranged in the box body 1 .

[0022] The driving device 5 drives the winding device 2 to run, so that the winding device 2 can wrap the paper tape 6 compactly and neatly, so that the recovered paper tape 6 is easy to use, and the cleaning device 3 can absorb the impurities and dirt adsorbed on the surface of the paper tape 6 to ensure that the paper tape 6 Clean, avoid scratching the lead frame when using the paper tape 6, avoid scrapping the lead frame, and reduce production costs.

Embodiment 2

[0024] In this embodiment, on the basis of Embodiment 1, further, the winding device 2 includes a first rotating shaft 202 and a second rotating shaft 204 penetrating and fixed on the front wall of the box body 1, and the first rotating shaft 202 is sleeved There is a first material tray 201, a second material tray 203 is sleeved on the second rotating shaft 204, and a guide wheel 205 is fixed between the first material tray 201 and the second material tray 203, and the guide wheel 205 is There are 2 to 4 tension adjustment shafts 206 fixed on the side, and the paper tape 6 is wound on the first tray 201, the guide wheel 205, the tension adjustment shaft 206 and the second tray 203 in turn, and the guide wheel 205 ensures that the wound paper tape 6 The end face is neat, and the tension adjustment shaft 206 ensures that the paper tape 6 wrapped tightly under a certain tension ensures a compact and neat winding paper tape 6, making the recycled paper tape 6 easy to use.

Embodiment 3

[0026] In this embodiment, on the basis of Embodiment 1, further, the cleaning device 3 includes two collection boxes 301 respectively fixed on the underside of the first tray 201 and the second tray 203, and the two collection boxes The back sides of 301 are all communicated with and fixed with one end of the air intake pipe 303 pierced on the front wall of the box body 1, and the other ends of the two air intake pipes 303 are connected and fixed on the vacuum pump 302 arranged in the box body 1, and the vacuum pump is started 302, the vacuum pump 302 makes the collection box 301 form a vacuum negative pressure state through the air intake pipe 303, thereby sucking the impurities and dirt adsorbed on the surface of the paper tape 6 into the collection box 301, ensuring that the paper tape 6 is clean and avoiding scratches when using the paper tape 6 Rubbing the lead frame avoids scrapping the lead frame and reduces production costs.

Abstract

The invention discloses lead frame paper tape recycling and cleaning equipment. The equipment comprises a box body, a supporting device is fixed to the bottom wall of the box body, a winding device and a cleaning device are sequentially fixed to the front wall of the box body from top to bottom, and the winding device is connected with a driving device arranged in the box body. The driving devicedrives the winding device to operate, so that the winding device compactly and neatly winds paper tape, and the recycled paper tape is convenient to use. The cleaning device can suck out impurities and dirt adsorbed on the surface of the paper tape, it is ensured that the paper tape is clean, a lead frame is prevented from being scratched when the paper tape is used, the lead frame is prevented from being scrapped, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of semiconductor integrated circuit equipment, in particular to a recovery and cleaning equipment for lead frame paper tapes. Background technique [0002] As the chip carrier of the semiconductor integrated circuit, the lead frame realizes the electrical connection between the lead-out end of the chip internal circuit and the outer lead wire by means of the bonding gold wire, forms a key structural part of the electrical circuit, and acts as a bridge connecting the external wire. The lead frame is an electronic An important basic component in the information industry. The production of lead frame has two kinds of stamping method and etching method. The stamping method mainly includes four processes of stamping, electroplating, forming and sorting. The thickness of copper strip material commonly used in lead frame production is between 0.1-0.254mm. In mass stamping production, paper tapes are widely used as turnover ...
