Description
Technical Field
The invention relates to the technical field of white oil board forming, in particular to a white oil board forming and stacking method.
Background
The requirements of dimensional tolerance of a molding part are different in a processing procedure of the circuit board due to different shapes and dimensional specifications of the circuit board, and for the circuit board industry, the mechanical processing principles of the molding procedure are consistent, and only for different products, certain differences exist in the processing technology modes and mainly exist in the differences of product types. The conventional operation modes are that a base plate is additionally arranged on a machine table, a matched finished product plate is arranged on the base plate, and the machine table can be processed according to programming, and certainly, for some special products, an auxiliary base plate and the like can be additionally arranged on a matched finished product, so that the processing of products in the process is realized, and the quality requirement of the products is ensured.
The whole board white oil circuit board is not only solder resist oil or character oil, but also white oil with uniform thickness on the whole board except exposed and welded welding pads. The quality requirements of the product are as follows: 1. the white oil part must be smooth and uniform, and visual differences of cleanliness such as grinding marks, scratches and the like cannot be generated, and except for vision, the key point is the uniformity of the voltage-resistant effect of the whole circuit board after the power is switched on; 2. the positions corresponding to the routing slots and the white oil positions of the appearance positions in the board are smooth, and the phenomena of white oil burrs, edge white oil splitting and the like are avoided.
At present, the white oil board forming and stacking operation modes mainly comprise the following two modes. The first method is as follows: increase bottom plate or backing plate in white oil board bottom, this kind of lamination mode can satisfy the requirement basically to the ordinary board that does not have surface cleanliness and edge burr requirement, nevertheless to the circuit board of the whole board white oil characteristic of similarity, this kind of operation mode easily leads to 100% product quality bad appearance, this kind of bottom plate + lamination mode of circuit board, gong head, gong sword, the brush of circuit board top direct contact gong machine. In the operation engineering of machinery, a head, a cutter and a brush are directly contacted with a white oil surface, so that the white oil is seriously scratched, white oil burrs are generated at a milling groove, and the white oil at the edge of the groove is split due to heating and stress. The second method comprises the following steps: increase bottom plate or backing plate in the bottom of white oil board, increase the apron at the top of white oil board, the setting of apron has avoided the direct contact of circuit board with gong head, gong sword, brush, reduces the operation in-process, and the circuit board is unusual because of the quality that direct contact leads to. The operation mode solves the problem of poor quality caused by direct contact to a great extent, but partial scratch also occurs between the cover plate and the circuit board due to force action, and the operation mode can only be operated in a single piece, is not suitable for batch operation and has low efficiency.
