Description

Technical Field

[0001] The utility model belongs to the technical field of PCB milling cutter production and relates to a table cleaning device for a PCB milling cutter bar forming press. Background Art

[0002] PCB Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, the support body of electronic components, and also the carrier of electrical connection of electronic components. Because it is made by electronic printing technology, it is called printed circuit board. In the process of PCB processing, PCB milling cutter is needed to cut grooves on the board to facilitate circuit design, so PCB milling cutter has been widely used.

[0003] When producing PCB milling cutters, powder raw materials need to be pressed into rods and then sintered to form them. When the molding press presses the powder, the powder raw materials need to be filled into the lower mold. A small amount of powder will fall onto the table of the molding press, which requires the operator to clean it regularly, increasing the operator's labor intensity.

[0004] Based on this, we designed a table cleaning device for PCB milling cutter bar forming press. Utility Model Content

[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and propose a table cleaning device for a PCB milling cutter bar forming press. The technical problem to be solved by the device is: how to realize automatic cleaning of the table of the PCB milling cutter forming press and reduce the labor burden of the operator.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0008] A slide groove is provided on the swing arm, and a slider is slidably provided in the slide groove, and the connecting pipe passes through the slider. A plurality of positioning holes are provided on one side of the slide groove, and a hand bolt is threadedly connected in one of the positioning holes, and the end of the hand bolt is against the slider.

[0009] With the above structure, the operator can change the position of the slider in the slide groove, change the position of the dust hood, and then lower and fix it by hand-tightening the bolts, so that the device can be applied to forming press tables with different layouts, expanding the scope of application of the device.

[0010] The width of the dust collection hood gradually decreases from top to bottom.

[0011] With the above structure, when the dust hood absorbs the powder below, the structure that is wide at the top and narrow at the bottom can increase the wind speed and suction force of the lower opening of the dust hood, thereby improving the suction effect.

[0012] The support column is provided with a sliding hole, and a lifting rod is slidably arranged in the sliding hole. The cover body is fixedly connected to the lifting rod. A sealing ring is provided under the cover body, and the sealing ring is against the inner edge of the aggregate barrel. The aggregate barrel is placed on the mounting base.

[0013] With the above structure, when the aggregate barrel is full of powder, the operator can lift the cover upwards and then replace the empty aggregate barrel or pour out the powder in the aggregate barrel, which is convenient for the operator to recycle the powder.

[0014] A filter is provided below the cover body, and the filter is located below the exhaust hole.

[0015] With the above structure, when the gas in the collecting barrel is discharged outward, the filter can prevent the powder from being discharged along with the gas, thereby improving the collection effect.

[0016] The wall of the aggregate barrel is made of transparent material.

[0017] The above structure makes it convenient for the operator to observe the amount of powder collected inside the aggregate barrel and to process the filled aggregate barrel in time.

[0018] Compared with the existing technology, the table cleaning device for PCB milling cutter bar forming press has the following advantages:

[0019] 1. Through the collection barrel, fan, venturi tube and hose, the adsorption effect of the venturi tube is used to adsorb the powder on the molding press table and carry it to the collection barrel, realizing the effect of automatic powder collection. It does not require manual cleaning by the operator, reducing the labor burden of the operator.

[0020] 2. The position of the dust hood is changed by the slider and the hand-tightening bolts, thereby changing the moving trajectory of the dust hood, so that the mounting base can adapt to more installation positions. The device can be applied to forming press tables with different layouts, expanding the scope of application of the device.

[0021] 3. Through the lifting rod, cover and sealing ring, the operator only needs to lift the cover to take and put the aggregate barrel. With the transparent aggregate barrel, it is convenient for the operator to replace the empty aggregate barrel or pour out the powder in the aggregate barrel, which is convenient for powder recycling.
