Description

Material bonding unit and material bonding test apparatus including the same {Materials bonding unit and bonding material tester}

The present invention relates to a material adhesion unit and a material adhesion test apparatus comprising the same.

Bonding automotive materials is mostly progressed through welding, but recently, the use of adhesives is gradually increasing as an alternative to welding automotive materials. In particular, the use of adhesives has been actively promoted for the purpose of shock absorption due to soundproofing, waterproofing and vibration of automobile assembly parts.

For the purpose of evaluating the adhesion of automobile materials, the quality of materials and adhesives is evaluated through the production of test specimens. The test specimen manufacturing process is to assemble the space material at the end of the material, measure the length from the assembled space member, and mark the adhesive coating area of the material with a line. Fix the space material. In other words, two space members corresponding to the thickness and area of the adhesive for the test purpose are assembled at regular intervals.

The process is repeated and continuously until the fixing of the space material of the prepared material is completed.

When the fixing of the space member for controlling the thickness and area of the adhesive to be applied for the experimental purpose of the prepared material is completed, a certain thickness of the adhesive is applied to the surface portion of the material whose thickness and area are controlled. When the application of the adhesive is completed on the surface of the plurality of material seated at regular intervals, another material is placed in close contact with the upper side opposite to the longitudinal direction of the material on which the adhesive is applied. At this time, the excess adhesive in the controlled thickness and area protrudes from side to side, and the protruding adhesive is removed using a knife, and a pair of materials attached to the upper and lower adhesives is fixed using a clip.

Then, the contact material up and down in the lengthwise direction through the applied adhesive is charged into the oven fixed with a clip and baking is carried out at the temperature and time of the experimental purpose.

The material fixed by baking is cooled at room temperature for a certain time, and the material after cooling is removed from the tape, space member and clip assembled for adhesive application and control purposes. Evaluate.

Evaluation of adhesiveness using the automotive materials described above requires a very large amount of evaluation materials depending on the adhesive, the type of material applied, the test method, and the conditions, and a problem of time delay occurs due to repetitive operations and processes. In particular, it takes a lot of time for the adhesive thickness and the application area to be controlled for the experimental purpose as the length measurement and the tight fixation of the repetitive space using the tape proceed.

In addition, for the subsequent tensile experiments, since the adhesive is applied between the materials protruded in different directions in the longitudinal direction and stacked up and down, the fixing of the upper and lower materials using the clips is inevitable, and the upper and lower contact fixing of the materials using the clips is oven In the baking process, there is a problem of causing deformation due to interference with the material, and thus, there is a disadvantage in that it is time delay as well as an experiment cost and an expense due to the repeated production of the evaluation material.

In addition, there is a problem that the adhesive is protruded from side to side in the process of being inserted into the oven and baked in the fixed state of the upper and lower materials by the clip, and it is difficult to remove the clip, and also the material by the clip during the heating process in the oven. Due to the nonuniform heat transfer therebetween, there is also a problem that the reliability of the experiment is lowered due to nonuniform coagulation of the adhesive.

Therefore, it is necessary to study the material adhesion unit and the material adhesion test apparatus including the same for solving the above problems.
