Description

Adjustable screening-in type PCB jig frame

Technical Field

The utility model relates to the field of PCBs (printed circuit boards), in particular to an adjustable screening-in type PCB jig frame.

Background

In the manufacturing of the electronic industry, the PCB has various specifications and sizes, and when the PCB finishes certain processes, solder paste, welding slag, soldering flux and the like sometimes need to be cleaned on the surface. Different PCB specifications need to be fixed by a jig frame and then put into a cleaning machine for cleaning.

In large-scale mass production at the present stage, a corresponding jig frame is generally adopted for one specification of a PCB. And the equivalent is few, or the sample stage of a plurality of products, and the PCB board of different specifications adopts different tool frames, and the corresponding tool is many, and occupation space is big, and the cleaning efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an adjustable screening-in type PCB jig frame which is high in cleaning efficiency and small in occupied space.

The utility model discloses an adjustable screening-in type PCB jig frame which comprises a frame, a plurality of tool strips and a sliding block assembly, wherein the plurality of tool strips are arranged on the frame in parallel, two ends of each tool strip are arranged on the frame through the sliding block assembly, and the tool strips can slide relative to the frame through the sliding block assembly.

Preferably, the sliding block assembly comprises at least one sliding block, one end of the sliding block is detachably fixed on the frame, and the other end of the sliding block is detachably fixed on the tool strip.

Preferably, the slider is provided with a groove, and the side strip of the frame is clamped in the groove.

Preferably, the sliding block and the side edge strips are fixed by a claw screw.

Preferably, the side edge of the tool strip is provided with a clamping groove along the length extension direction.

Preferably, the end of one end of the clamping groove is in a round angle shape.

Preferably, the end of the other end of the clamping groove is closed.

Preferably, the frame is further provided with a handle.

The beneficial effects disclosed by the utility model are as follows: through slider assembly between frock strip and frame, and slider assembly is for the frame slidable, so the distance is adjustable between the frock strip, adjusts to the width of difference and can deal with the PCB board of different specifications. The PCB boards with different specifications only need to adopt the jig frame with one specification. The occupied space is greatly reduced, and the cleaning efficiency is also greatly improved.

Detailed Description

The utility model will be further elucidated and described with reference to the embodiments and drawings of the specification:

referring to fig. 1 and 3, an adjustable screen-in PCB jig frame includes a frame 10, a plurality of tool bars 20, and a slider assembly 30. The plurality of tool bars 20 are mounted in parallel to the frame 10. Both ends of the tool bar 20 are mounted to the frame 10 by the slider assemblies 30, and the tool bar 20 is slidable with respect to the frame 10 by the slider assemblies 30.

Referring to fig. 2 and 4, the slide assembly 30 includes at least one slide 32, one end of the slide 32 is detachably fixed to the frame 10, and the other end of the slide 32 is detachably fixed to the tool bar 20.

The slide block 32 is provided with a groove 34, and the side edge strip 12 of the frame 10 is clamped in the groove 34.

The sliding block 32 and the side bar 12 are fixed by a claw screw 40.

The side edge of the tool strip 20 is provided with a clamping groove 22 along the length extending direction. The end of one end of the clamping groove 22 is a round angle. The end of the other end of the clamping groove 22 is closed. When the PCB board inserts, the draw-in groove of fillet can be fine avoid the fish tail of face.

The frame 10 is also provided with a handle 50.

The beneficial effects disclosed by the utility model are as follows: through slider assembly between frock strip and frame, and slider assembly is for the frame slidable, so the distance is adjustable between the frock strip, adjusts to the width of difference and can deal with the PCB board of different specifications. The PCB boards of various different specifications only need to adopt the tool frame of a specification. The occupied space is greatly reduced, and the cleaning efficiency is also greatly improved.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
