Description
Technical Field
[0001] The utility model belongs to the field of semiconductor chip COF packaging, and particularly relates to an arc-shaped support rail for improving material strip tearing. Background Art
[0002] In the existing technology, COF is a soft film assembly technology for fixing integrated circuits (ICs) on material strips (flexible circuit boards). At the ILB station of COF, after the IC chip is pressed onto the PI film of the material strip, the gold ball under the chip will bond with the wires in the PI film. This process is called inner wire bonding. At present, the track of the ILB station is a straight support rail. The bonding area is where the IC crystal uses the gold layer on the back to the gold-plated surface in the center of the fixed frame for an instant high temperature mechanical compression welding. The track is disconnected in the bonding area to leave a gap for the punch to move up and down and press. The disadvantage is that the straight support rail is easy to pass the traction belt under the support rail when the material strip is passed, or the material strip is transferred to the gap when it is punched, and the punching depression hits the fracture of the auxiliary rail, causing the product material strip to be damaged and torn, which also affects production efficiency. Utility Model Content
[0003] The purpose of the utility model is to provide an arc-shaped support rail for improving the tearing of material strips, which can shorten the spacing of the disconnected gaps of the linear support rail in the bonding area, prevent the material strip from being sunken and scratched or collided with the support seat; effectively reduce the abnormal occurrence rate of material strip transmission caused by punching sunken, reduce product losses, and improve production efficiency.
[0004] The purpose of the utility model is achieved as follows: an arc-shaped support rail for improving the tearing of a material strip, comprising a transmission guide rail 1 and a transmission guide rail 2 spaced apart from each other, the transmission guide rail 1 and the transmission guide rail 2 are distributed along the same straight line and have the same height, a support seat is provided between the transmission guide rail 1 and the transmission guide rail 2, the surface height of the support seat is lower than the height of the transmission guide rail 1, support beams are provided on the left and right sides of the transmission guide rail 1 and the transmission guide rail 2, the support beams are parallel to the length direction of the transmission guide rail 1, placement grooves are provided on the left and right opposite sides of the two support beams, the left and right sides of the shielding cover plate are respectively supported on the bottom inner walls of the two placement grooves, the transmission guide rail 1 and the transmission guide rail 2 are provided with an arc-shaped guide rail extending downward at the opposite ends, and the two arc-shaped guide rails are symmetrically distributed front to back.
[0005] The utility model is used for conveying material belts. A lifting punch is correspondingly provided above the support seat. The gap between the first and second transmission guide rails enables the punch to bond the material belt portion on the support seat. The shielding cover is made of transparent plastic material to prevent dust and other foreign particles from falling on the material belt product. The arc guide rail plays a supporting role when the punch moves, and can also guide the material belt transmission. Compared with the prior art, the beneficial effects of the utility model are: the spacing between the two sections of the support rails can be reduced. When the material belt is conveyed after being dented by the punching hole, it can be buffered by the arc auxiliary rail. After buffering, the material belt can be continuously and smoothly conveyed, reducing the abnormal occurrence rate of scratches and collisions between the material belt and the support seat, reducing product losses, and improving production efficiency; the arc buffer auxiliary rail is suitable for the operation of material belt products with a width of 35, 48, and 70 mm, does not affect the machine change operation, and has good adaptability.

The two connecting plates are respectively hinged to the left and right sides of the corresponding transmission guide rail via a rotating shaft.

The two screw holes on the side of the transmission guide rail are fixed, and after the mounting portion is rotated, the bolts pass through the corresponding two adjusting holes of the mounting portion and are fixed to the transmission guide rail, so that the arc guide rail can be rotated around the rotating shaft to adjust the angle position.
[0008] As a further improvement of the utility model, a row of equally spaced side positioning blocks are arranged on both sides of the surfaces of the first and second transmission guide rails, and the side positioning blocks are arranged in an isosceles trapezoidal shape. The side positioning blocks on both sides position the left and right sides of the material belt.
[0009] As a further improvement of the utility model, bases are provided correspondingly below the transmission guide rail 1, the transmission guide rail 2 and the two supporting beams.
