Description

Technical Field

[0001] The utility model belongs to the field of semiconductor COF packaging, and in particular relates to a dual IC product operation supporting device. Background Art

[0002] During COF packaging production, the wafer is first cut into several small IC chips, and then each IC chip is bonded and fixed on the flexible circuit board (material strip) through a bonding machine. The flexible circuit board is transmitted on the guide rail, and the bonding machine fixes the IC and the substrate of the material strip. For the material strip product with two ICs fixed on the substrate, if a defective IC appears, it is necessary to use a punch to punch out the defective IC on the material strip. The problem is: for the material strip product with two ICs fixed on the substrate, the punched holes are larger, resulting in a larger bend of the material strip at the punching point of the double IC material strip product during punching, and the material strip is easily scratched on the horizontal support track, causing damage to the material strip. Utility Model Content

[0003] The utility model aims to provide a dual IC product operation support device, which can prevent the material strip from bending when punching the material strip, causing the material strip to scrape against the support rail and cause wear, thereby protecting the material strip and ensuring the normal operation of the machine.

[0004] The purpose of the utility model is achieved as follows: a dual IC product operation support device, including two parallel side guides, the cross-section of the side guides is L-shaped, the side guides include a horizontal portion and a vertical portion, the horizontal portions of the two side guides are relatively arranged, a lower support rail is arranged between the two side guides, a material strip is placed on the lower support rail along the length direction, the left and right side edges of the material strip are respectively supported on the corresponding horizontal portions of the side guides, the width of the material strip is set corresponding to the spacing of the vertical portions of the guide rails on both sides, the lower support rail includes a horizontal guide body, the front and rear ends of the guide body are provided with arc-shaped guide portions, the left and right sides of the upper surface of the guide body are arranged in sequence and equidistantly along the length direction with a plurality of upwardly protruding arc-shaped support portions, the guide body is fixed to the base by a plurality of fasteners, and a plurality of mounting holes for the fasteners to pass through are opened on the guide body.

[0005] The material belt of the utility model moves on the lower supporting guide rail under the driving action of the material discharge tray and the material collection tray. The guide rails on both sides provide position-limiting support to the left and right edges of the material belt, so that the movement of the material belt is more stable and smooth, and the operation is safer. By adding a plurality of upwardly protruding arc-shaped supporting parts to the left and right edges of the lower supporting guide rail, a spacing is left between the lower surface of the material belt and the horizontal part of the side guide rail. Compared with the prior art, the beneficial effects of the utility model are: not only the friction between the lower surface of the material belt and the lower supporting guide rail is reduced during transmission, but also when punching holes in the material belt, the material belt is prevented from bending and causing the material belt to scrape against the supporting rail and cause wear, thereby protecting the material belt and ensuring the normal operation of the machine.

[0006] As a further improvement of the present invention, the thickness of the guide rail body is 6.4-6.6 mm, the top height of the support portion is 1.4-1.6 mm, and the width of the guide rail body is 24-26 mm.

[0007] As a further improvement of the present invention, 3-5 mounting holes are arranged at intervals on the guide rail body. The multiple mounting holes make the connection between the lower support guide rail and the base more secure, and the mounting holes are countersunk holes, so that the fasteners will not scratch the material strip.

[0008] As a further improvement of the utility model, at least two parallel connecting strips are longitudinally arranged on the outer side of the side guide rails, and a fixed transverse beam is arranged corresponding to the outer sides of the two side guide rails. A plurality of longitudinal fixed strips are arranged on the fixed transverse beam corresponding to each connecting strip, and waist-shaped grooves are arranged on the fixed strips, screw holes are arranged on the connecting strips, and the outward end of the connecting strips is supported on the corresponding fixed strips, and the fastening bolts pass downward through the corresponding screw holes and waist-shaped grooves, and nuts for locking the fixed strips are sleeved on the ends of the fastening bolts. After loosening the fastening bolts, the spacing between the two side guide rails can be adjusted by longitudinally moving the connecting strips of the side guide rails relative to the waist-shaped grooves of the fixed strips of the fixed transverse beams to adapt to material strips of different widths.

[0009] As a further improvement of the utility model, at least two lower support rails are provided, and a lower support seat is provided between the two adjacent lower support rails. A punch is provided above the support seat, and the support seat between the two lower support rails facilitates the punch to be raised and lowered to punch holes in the material strip.
