Problems solved by technology

[0003] At present, there are difficulties in feeding PCB board laminators, and many presses use cylinder-type push-pull methods, which have uneven stress points, resulting in deformation, warped edges, and unevenness in lamination. At the same time The push-pull of the cylinder type is under a large force, which will reduce the service life of the cylinder. At the same time, when the operator is feeding the material, he will receive the weight of the circuit board, and the labor intensity will be high during the pushing process. Combined quality and effect

Embodiment 1

[0038] A circuit board pressing method, such as Figure 1-Figure 5As shown, including the body 1, the interior of the body 1 is provided with a cavity 2 for pressing the circuit board up and down, the cavity 2 is provided with a pressing mechanism 3 for pressing, and the front part of the body 1 is provided with a pair of cavity 2 The sealing mechanism 4 for sealing, the bottom of the body 1 is fixedly connected with the base 5, the inside of the body 1 is provided with a limit auxiliary mechanism 9 for auxiliary positioning of the circuit board, and the inside of the body 1 is fixedly installed with a pressure relief valve 7 and an inflation valve 8 ;

[0039] A circuit board pressing method comprises the following steps:

[0040] Step 1: Feeding, the operator pushes the stacked circuit boards from the position of the material inlet to the pressing table;

[0041] Step 2: seal, then the oil cylinder 41 is extended, and the airtight door 42 is controlled to rise and move. Wh...

Embodiment 2

[0054] Such as Figure 6 As shown, the limit auxiliary mechanism 9 includes a connection block 93, the surface of the connection block 93 is connected with an upper support plate 91 and a lower support plate 92 by bolts, the connection block 93 is fixedly connected with an inflation nozzle 96, the upper support plate 91 and the lower support plate Air bag bar three 95 is arranged in the cavity that support plate 92 forms, and the end of air bag bar three 95 is fixedly connected on the lower support plate 92 by bolts, and the upper support plate 91 is slidably connected with sliding connecting plate 97, and the limit of setting Auxiliary mechanism 9 makes the process of pushing the circuit board more convenient, fast, and more labor-saving, and after the inflation and deflation of the air bag strip 3 95, the position of the circuit board can be placed, avoiding manual handling Finding a location is time-consuming and labor-intensive.

[0055] In this embodiment, several push b...

Abstract

The invention relates to the technical field of circuit boards, and particularly relates to a circuit board pressing method which comprises a machine body. A cavity for pressing a circuit board up and down is arranged in the machine body, a pressing mechanism for pressing is arranged in the cavity, and a sealing mechanism for sealing the cavity is arranged at the front part of the machine body. The bottom of the machine body is fixedly connected with a base, and a limiting auxiliary mechanism for auxiliary positioning of the circuit board is arranged in the machine body. According to the circuit board pressing method, the whole circuit board pressing process can be more comprehensive through an arranged air bag strip inflation expansion pressing mode, deformation and edge warping conditions are reduced, the circuit board pressing method is very convenient, the quality of the pressed circuit board can be greatly improved, meanwhile, the rotating bearings are arranged on the two sides of the workbench so that the two sides of the circuit board are limited in the pushing process, the auxiliary sliding effect is achieved, and the circuit board is pushed more smoothly.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a circuit board pressing method. Background technique [0002] The PCB board is called a printed circuit board or a printed circuit board, and it is a provider of electrical connections for electronic components. Generally speaking, printed circuit boards: one layer / two layers of copper foil (conductive layer) are covered on the non-conductive substrate-called single / double-sided circuit boards, and then the designed circuit is printed by printing method. Print the lines to be kept (corrosion-resistant medium) on the copper foil, immerse in the corrosive liquid to corrode the copper foil without protective coating, wash off the corrosive residual liquid, position and punch holes, apply flux, etc., It's done. The role of the PCB board is like the need for crops to grow in the soil: one is to provide electrical connections between electronic components through copper foil ...
