Description

Technical Field

[0001] The invention relates to the technical field of PCB board hole plugging, and in particular to a clean vacuum resin hole plugging machine. Background Art

[0002] PCB, Chinese name for printed circuit board, also known as printed circuit board, is an important electronic component, the support of electronic components, and the carrier of electrical connection of electronic components. Because it is made by electronic printing technology, it is called "printed" circuit board.

[0003] Traditionally, the production of PCB boards requires the use of a screen printer to plug holes. The specific operation can be roughly divided into two steps. First, the stencil fixed on the screen printer is aligned with the PCB board, and then the screen printer plugs holes in the PCB board through the stencil. Most existing stencils use an "aluminum sheet + mesh" structure. Traditional whole-board plugging has the risk of the front plugging head sealing strip being stained with ink on the oily surface, thus contaminating the oily surface. Summary of the invention

[0004] The object of the present invention is to provide a clean vacuum resin plugging machine to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a clean vacuum resin plugging machine, comprising a machine body, a vacuum chamber body is arranged inside the machine body, a sealing chamber door is arranged on the top of the vacuum chamber body, a clamping plate seat is fixedly installed, a plug module that can be lifted and slid is arranged inside the vacuum chamber body, the plug module comprises a module frame and two groups of plug bases, the two groups of the plug bases are detachably installed on both sides of the module frame, and the two groups of the plug bases are driven by a translation driving device to slide in relative directions, a front plug and a rear plug are fixedly installed on the inner sides of the two groups of the plug bases, a single-strand seal is installed on the outer side of the front plug, a double-strand seal is installed on the outer side of the rear plug, and an oil outlet is arranged inside the rear plug, the oil outlet is located on the inner side of the double-strand seal, and the height of the single-strand seal in the vertical direction is lower than the height of the oil outlet on the PCB board surface, and the translation driving device drives the front plug and the rear plug to approach each other to clamp the PCB board.

[0006] Preferably, a lifting drive is provided between the two ends of the plug module and the vacuum chamber body, the lifting drive is an electric screw assembly, and the two ends of the plug module are slidably matched with the inner walls of both sides of the vacuum chamber body, and the lifting drive drives the plug module to lift vertically.

[0007] Preferably, an electric control cabinet is provided on one side of the machine body, and a touch screen is provided above the electric control cabinet.

[0008] Preferably, the outside of the front plug and the rear plug are respectively provided with engaging grooves for installing a single-strand seal and a double-strand seal.

[0009] Preferably, the module frame includes two groups of cross frames and two groups of guide rods, two ends of the cross frame are respectively slidably matched with the two groups of guide rods, and the plug base is snap-fitted and installed on the outside of the cross frame.

[0010] Preferably, both ends of the cross frame are fixedly connected with linear bearings, and the linear bearings are slidably sleeved on the outside of the guide rod.

[0011] Preferably, the translation drive device is a cylinder, which is installed on the outside of the cross frame, and a connecting plate is fixedly connected to the outside of the cylinder.

[0014] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0015] 1. The present invention vertically hangs the whole board circuit board on the clamping plate seat in the vacuum chamber, and draws vacuum. The front plug and the rear plug are pushed by the cylinder to clamp the board. The ink begins to fill the holes of the board that need to be plugged with resin. At the same time, the plug module is controlled to move downward. The rear plug uses a double-strand seal and the front plug uses a single-strand seal. The plugging process is from top to bottom. The single-strand seal is on the oiling surface of the board and is lower than the single-strand seal, so that the plugging of the whole board will not scrape the oiling hole position on the PCB board surface, and will not pollute the oiling panel surface. The front plug with a single-strand seal can completely avoid the risk of the seal sticking to the ink on the oiling surface and polluting the oiling surface, thereby achieving the purpose of plugging the whole board and selectively plugging the holes, while reducing the production time and cost of the jig, reducing the complex process of plugging the holes of the traditional silk screen printing machine, and completely replacing the traditional silk screen printing machine;

[0016] 2. The present invention configures the module frame as a combination of a cross frame and a guide rod, and utilizes the sliding of linear bearings to support the sliding of the two groups of plug bases towards or away from each other, thereby ensuring the precise matching of the front plug and the rear plug. By providing a card slot inside the plug base, the plug base can be snap-fitted and installed on the outside of the cross frame, and the plug base and the cross frame are locked by inserting a pin into the pin hole. This ensures that the plug base is firmly installed while facilitating disassembly, replacement or maintenance of the plug base, further improving the convenience and adaptability of the equipment.
