Embodiment Construction
[0024] Such as figure 1 , figure 2 , image 3 As shown, a kind of vacuum fixture for PCB board of the present invention comprises:
[0025] A bottom plate 1, a sliding device 2 is fixedly arranged below the bottom plate 1. There are two sliding devices 2, and the two sliding devices 2 are arranged below the bottom plate 1 in parallel. The sliding device 2 includes a sliding guide rail 201, a sliding block 202 arranged on the sliding guide rail 201, The sliding block 202 is fixedly connected to the lower surface of the bottom plate 1 . Handles 13 are respectively formed on both sides of the upper surface of the bottom plate 1 .
[0026] Support rods 3, the four support rods 3 are formed on the four corners of the upper surface of the bottom plate 1, the upper ends of the support rods 3 are formed with a push rod 4, and the push rod 4 is covered with a support sleeve 5 , the top end of the push rod 4 is formed with a stud 401 . The diameter of the support rod 3 is larger ...

The invention discloses a dust collection jig used for a PCB. The dust collection jig comprises a bottom plate, sliding devices, supporting rods, ejector rods, supporting plates, a top plate, first nuts, positioning rods, first gaskets, second gaskets, second nuts, a handle and the like. By arranging the supporting rods and the supporting plates above the bottom plate, a PCB substrate can be fixed above the supporting plates and is positioned through the positioning rods on the top plate, the dust collection operation can be conducted on the PCB substrate by only arranging a dust collection device above the top plate, operation is easy, the dust collection effect is good, and the labor cost is saved. A sliding device is arranged below the bottom plate, the sliding device can drive the PCB substrate above the bottom plate to slide for the small-diameter dust collection device, and therefore dust collection can be conducted on the whole substrate, and the dust collection effect is further improved. By forming positioning grooves in the top plate, forming through grooves in the supporting plates and positioning the PCB substrate through the positioning rods, the requirement for positioning PCB substrates of different sizes is met, and applicability is wide.
Description
Technical field: [0001] The invention belongs to the technical field of PCB board fixtures, in particular to a dust suction fixture for PCB boards. Background technique: [0002] PCB board, also known as printed circuit board, printed circuit board, referred to as printed board, is based on an insulating board, cut to a certain size, with at least one conductive pattern attached to it, and holes (such as component holes, fastening Holes, metallized holes, etc.), used to replace the site where electronic components were installed in the past, and to realize the interconnection between electronic components. Since this board is made by electronic printing, it is called a printed circuit board. Existing PCB boards need to drill holes in the copper board during production. After the copper board is drilled, the dust generated under the action of the high-speed drill bit will partially remain in the hole. In order to ensure product quality, the printed board body needs to be Af...
