[0032] The following is a preferred embodiment of an ACF feeding and attaching device provided by the utility model that can solve the above technical problems.

[0033] Please refer to Figure 1-Figure 3 In the figures, units with similar structures are represented by the same reference numerals.

[0034] The utility model provides an ACF feeding and attaching device, which comprises an ACF feeding reel 11, an attaching robot 12, a material pulling robot 13, a first cutting component 14, and a second cutting component 15.

[0035] The first cutting assembly 14 is located at one end of the second cutting assembly 15 close to the attaching robot 12, and the first cutting assembly 14 is used to cut the ACF provided by the ACF supply reel 11 into ACF finished sheets. Figure 4 The ACF finished sheet includes a laminated ACF glue body 21 and a film 22. The second cutting assembly 15 is used to cut the ACF provided by the ACF feeding reel 11 into a waste glue block 23, so that the film 22 on the subsequent ACF finished sheet has an extended section relative to the ACF glue body 21. The extended section forms an easy-to-tear handle of the film 22, which is convenient for subsequent film tearing operations.

[0036] The material pulling robot 13 is arranged on the side of the first cutting component 14 away from the second cutting component 15. The material pulling robot 13 is used to pull the ACF cut by the second cutting component 15 out to a set length for cutting by the first cutting component 14, wherein the pulled long strip can be controlled by the material pulling robot 13, so that the first cutting component 14 can cut out ACF finished sheets that meet the user's different length requirements.
