As shown in fig. 1 and fig. 2, when the inductor and the frameless transformer are designed for complete machine assembly, in order to prevent the inclination of the product when being inserted and fix the pin positions, a PCB 2 is added under the inductor or the frameless transformer as a bottom board to solve the above two problems. But adding a PCB board does not fully accommodate the shape of an inductive or frameless transformer. The PCB is a plane with a flat surface, the arc-shaped inductor and transformer products are not easy to fix on the PCB, the prior method of dispensing is adopted for fixing, and in order to ensure more reliable dispensing, a small PCB block 1 is respectively added at the left side and the right side for fixing, so as to reduce the glue amount and the reliability and operability of dispensing.

However, when the existing PCB structure is assembled, because each part has no reference for positioning limitation and is fool-proof, the existing PCB structure is positioned by manpower during production and processing, and the position of the small epoxy board can be positioned by a large amount of increased working hours, so that the small epoxy board does not have the phenomena of dislocation and the like. The process time is long and the production efficiency is low when the product is produced, so that the cost is increased, the appearance is poor in quality, and reworking and scrapping are caused.

SUMMERY OF THE UTILITY MODEL

To foretell not enough among the prior art, the utility model provides a convex electronic components dress board auxiliary device, the concave recess of establishing of electronic components surface circular arc and bottom plate surface is tangent, and pin hole is inserted to electronic components's pin to carry out the point to the pin hole and glue, and the back tangent point of gluing is three points altogether with 2 pins, can be stable fix electronic components on the device surface, and the pin hole can realize fixing a position, reduces the equipment time with a measure of preventing staying, improves production efficiency, yield and reliability, reduction in production cost.

In order to achieve the above object, the utility model discloses a solution is: the utility model provides a convex electronic components dress board auxiliary device, includes the bottom plate, bottom plate upper surface concave be equipped with the tangent convex recess of electronic components surface circular arc, still set up the pin hole that is used for inserting the electronic components pin on the bottom plate.

Furthermore, the curvature radius of the arc-shaped groove is larger than that of the surface arc of the electronic component.

Furthermore, the number of the pin holes is 2, and the pin holes are respectively arranged on two sides of the arc-shaped groove.

Furthermore, the electronic components are inductors and frameless transformers.
