AI Technical Summary
Technical Problem
Existing sheet attaching devices for semiconductor wafers require time-consuming and costly replacement of adhesive sheets, which can be operator-dependent and prone to failure due to insecure connections, especially with wider sheets and increased wafer sizes.
Method used
A sheet connecting device using adhesive rollers to separate and connect adhesive sheets by forming a separation section, followed by heat welding or adhesive bonding to ensure secure attachment without additional adhesive members.
Benefits of technology
Facilitates rapid, cost-effective, and reliable connection of adhesive sheets, reducing waste and production downtime by eliminating the need for separate adhesive members and ensuring secure attachment even with wide sheets.

Abstract
[Problem] To provide a sheet connection device that can reliably connect a plurality of bonding sheets. [Solution] A sheet connection device 1 connects an upstream-side first bonding sheet S1 and a downstream-side second bonding sheet S2, and comprises: upstream-side adhesive rollers 10, 10; a joining part 20 and a cutting part 30 that are provided on the downstream side; and feeding rollers 40, 40 that are on the downstream side of these. The cutting part 30 can cut the second bonding sheet S2 in the width direction to form a connection-receiving end section SE2, and the adhesive rollers 10, 10 feed a connection end section SE1 of the first bonding sheet S1 toward the downstream side while sandwiching the same between the adhesive rollers 10, 10, thereby separating the first bonding sheet S1 into an adhesive sheet SA and a peel sheet SP and forming a separated section 50. The feeding rollers 40, 40 feed the second bonding sheet S2 toward the connection end section SE1, thereby inserting the connection-receiving end section SE2 into the separated section 50, and the joining part 20 connects the connection end section SE1 and the connection-receiving end section SE2 by adhesion or welding.
