PCB resin selective vacuum hole plugging machine

Abstract

The invention discloses a PCB resin selective vacuum hole plugging machine which comprises a base, a storage box is fixedly connected to the middle of the lower end of the base, a transfer pump is fixedly connected to the rear portion of the lower box wall of the storage box, a conveying pipe is fixedly connected to the middle of the rear end of the transfer pump in a penetrating mode, and a fixing mechanism is fixedly connected to the middle of the upper end of the base. A sealing cover is jointly and fixedly connected between the peripheries of the upper ends of the bases, a scraping mechanism is jointly and fixedly connected between the left cover wall and the right cover wall of the sealing cover, a hole plugging machine body is fixedly connected to the left portion of the upper end of the sealing cover in a penetrating mode, and the middle of the upper end of the hole plugging machine body is fixedly connected with the end, away from a material pumping pump, of a material conveying pipe in a penetrating mode. And the right part of the upper end of the sealing cover is fixedly connected with an air exhaust mechanism. According to the PCB resin selective vacuum hole plugging machine, the whole hole plugging machine is high in stability and good in hole screening effect, extracted gas can be purified, and the PCB resin selective vacuum hole plugging machine is suitable for wide application.

Description

technical field [0001] The invention relates to the technical field of plugging machines, in particular to a PCB resin selective vacuum plugging machine. Background technique [0002] With the continuous development of the electronics industry, the resin vacuum plugging technology of the PCB circuit board as the carrier of electronic products is gradually applied to more and more circuit boards, and in the production process, in order to make the PCB circuit board more suitable for various For electronic products to play a greater role, it is necessary to continuously optimize and improve the vacuum plugging machine while making good use of the resin vacuum plugging technology; [0003] The inventors have found that at least the following problems have not been resolved in the prior art: 1. The existing plugging machine has a poor fixing effect on circuit boards, and cannot fix circuit boards of different lengths, which reduces the practicability of the machine. And there i...

Problems solved by technology

[0003] The inventors have found that at least the following problems have not been resolved in the prior art: 1. The existing plugging machine has a poor fixing effect on circuit boards, and cannot fix circuit boards of different lengths, which reduces the practicability of the machine. And there is often residual resin on the circuit board, which is troublesome to clean up; 2. When the plugging machine is in use, the gas inside the machine needs to be extracted to form a vacuum environment inside the plugging machine, but most of the existing plugging machines use The pipeline directly extracts and discharges the gas, causing the dust and odor in the gas to be directly exported and discharged. If things go on like this, it will cause certain damage to the body of the staff; therefore, we propose a PCB resin selective vacuum plugging machine
