Description

technical field [0001] The invention relates to the technology of automobile electronics, in particular to the technology of a device for processing terminal pins of an integrated circuit board in an automobile electronic system. Background technique [0002] In the automotive safety system, there are terminal pins used to connect other components on the integrated circuit board. When producing each terminal pin, each terminal pin needs to be bent according to the design direction. [0003] The existing end pin bending equipment can only bend end pins of the same thickness each time. If end pins of different thicknesses are bent at the same time, the thin end pins will loosen due to insufficient clamping. As a result, the bending quality is affected, so that the thin end pins cannot meet the bending size requirements; therefore, when the end pins of the existing integrated circuit board are produced, it is necessary to use the end pin bending equipment to separate the end pi...

Problems solved by technology

[0003] The existing end pin bending equipment can only bend end pins of the same thickness each time. If end pins of different thicknesses are bent at the same time, the thin end pins will loosen due to insufficient clamping. As a result, the bending quality is affected, so that the thin end pins cannot meet the bending size requirements; therefore, when the end pins of the existing integrated circuit board are produced, it is necessary to use the end pin bending equipment to separate the end pins of different thicknesses in advance. The bending operation must be carried out in batches, and then the end pins can be inserted into the plastic shell in turn, and after being inserted into the plastic shell, sealant needs to be applied for sealing, and after the sealant is applied, it must be baked

[0004] Due to the defects of the existing terminal pin bending equipment, the production method of the existing terminal pins of the integrated circuit board has the following defects: 1) Since the terminal pins need to be bent in batches, and must be bent and then inserted into the plastic shell, And need to carry out sealing treatment, so its production time is longer, and production cost is also higher; 2) because also must carry out baking operation after coating sealant, therefore can produce certain pollution to environment, easily be engaged in this work for a long time 3) Due to many processes, bending equipment, injection molding equipment, gluing equipment and baking equipment are required, so the floor area is also large and the utilization rate of the site is low; 4) Due to different thicknesses The springback of the material after bending is different. After bending with the existing bending machine, the bending angle of the end pins with different thicknesses will be different, so the bending accuracy of the end pins is low.
