Problems solved by technology
[0002] T-squares are widely used in engineering drawing, teaching, and measurement. The existing T-squares on the market are mainly made of PMMA materials through adhesives. The bonding method of this type of T-squares not only uses chemical bonding Toxic materials such as solvents and other toxic materials, and this bonding method makes it impossible to accurately locate the sticking part, there is a large error in the sticking accuracy, and the sticking structure is not firm, causing the T-square to crack or loosen. The connection method seriously affects the accuracy and structural strength of the T-square

The invention discloses an ultrasonic bonding method for a J-shaped ruler. One end of a main ruler of the J-shaped ruler is connected to the middle of an auxiliary ruler of the J-shaped ruler in a J-shaped manner; and under the condition that pressure of 2.0 to 6.5 Mpa is applied to a joint of the main ruler of the J-shaped ruler and the auxiliary ruler of the J-shaped ruler, the joint is welded by ultrasonic welding equipment and then hardened. According to a theory that the ultrasonic welding equipment welds a thermoplastic material, the J-shaped ruler is bonded under the condition of no toxicity and no harmfulness; furthermore, the method has the advantages of high bonding speed and high bonding precision; and therefore, the structural strength of the J-shaped ruler is effectively improved, and the measurement error of the J-shaped ruler is reduced.
Description
technical field [0001] The invention relates to a T-square bonding method, in particular to an ultrasonic bonding method for a T-square. Background technique [0002] T-squares are widely used in engineering drawing, teaching, and measurement. The existing T-squares on the market are mainly made of PMMA materials through adhesives. The bonding method of this type of T-squares not only uses chemical bonding Toxic materials such as solvents and other toxic materials, and this bonding method makes it impossible to accurately locate the sticking part, there is a large error in the sticking accuracy, and the sticking structure is not firm, causing the T-square to crack or loosen. The connection method has seriously affected the accuracy and structural strength of the T-square. Contents of the invention [0003] The purpose of the present invention is to provide a T-square ultrasonic bonding method, which is non-toxic and can effectively improve the bonding accuracy and str...
