Description

Technical Field

[0001] This utility model relates to the field of SMT tape bonding technology, and in particular to an SMT tape bonding fixture. Background Technology

[0002] In paper production and other continuous production industries, such as SA (Self-Service) stations, non-stop roll changing is required to improve production efficiency and reduce downtime. Traditional roll changing methods require machine shutdown, which leads to reduced production efficiency and increased costs. Therefore, the research and application of non-stop roll changing technology has become an urgent need in the industry.

[0003] The core of the roll-changing technology that allows for continuous operation during production lies in the coordination of two sets of working wheels. Specifically, the roll to be replaced is mounted on a drive wheel, and the rotation of the movable working wheel slowly pushes out the old roll while simultaneously loading the new one. Connecting the old and new rolls is crucial and requires auxiliary tools. Existing SMT tape bonding methods involve manually cutting both sides, applying adhesive, pressing, and peeling. Manual bonding is inefficient, inaccurate in positioning, and prone to malfunctions after installation.

[0004] Therefore, we propose a novel SMT tape bonding fixture. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing SMT tape bonding methods, which involve manually cutting, applying adhesive, pressing, and peeling the tape on both sides. These manual bonding methods are inefficient, have inaccurate bonding positioning, and are prone to malfunctions after being installed on the machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an SMT tape bonding fixture, comprising a fixture body, two sets of cover plate hinges connected to the rear end of the fixture body, cover plate bodies connected to the surfaces of the two sets of cover plate hinges, a knife holder connected to one side of the cover plate body, rotating cover magnets symmetrically arranged at both the front and rear ends of the top surface of the fixture body, two sets of rotating cover bodies connected to the center of the top surfaces on both sides of the fixture body, two sets of material cavity positioning stops provided on the top surface of the fixture body, tape cutting positioning posts connected to both sides of the upper material cavity positioning stops, tape bonding positioning posts connected to both the front and rear ends of the lower material cavity positioning stops, and a knife edge avoidance position provided at the center of the upper material cavity positioning stops.

[0007] Furthermore, the blade is internally connected to the tool holder, and the cover plate body is rotatably connected to the fixture body via a cover plate hinge.

[0008] Furthermore, the position and size of the rotating cover body are matched with the position and size of the two sets of rotating cover magnetic stones, and the rotating cover body and the rotating cover magnetic stones form a magnetic connection.

[0009] Furthermore, the surface of the material strip adhesive positioning post is provided with a backing paper, and an adhesive layer is connected to the top of the backing paper.

[0010] Furthermore, a face paper is attached to the top of the adhesive layer.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this utility model, the positioning pin of the fixture is used to position the cutting and pasting position of the product, thus solving the problem of scrap caused by product misalignment. The upper and lower opening and closing structure of the fixture solves the problems of large burrs and deformation during the product cutting process. The fixture is a lightweight mechanical structure design that does not require power and is not limited by the place of use. Attached Figure Description
