The utility model proposes a kind of circuit board detecting auxiliary devices.

In the utility model embodiment, as shown in Figures 1 to 3, which includes clamp system and survey Test-run a machine structure, the clamp system includes the cylinder 2 being mounted in fixed link 23 and loaded on the handgrip component on cylinder 2, described to grab Hand component includes respectively symmetrically set on the drive rod 21 and clamp arm 22 of the axis two sides of cylinder 2, one end hinge of the drive rod 21 It is connected to the piston rod of cylinder, the other end and the middle part of clamp arm 22 are hinged, and the rear end of clamp arm and the cylinder body of cylinder 22 are hinged, cylinder 22 Piston rod it is flexible when, push two clamp arm to swing by drive rod so that the front of two clamp arm by be located at two clamp arm front it Between circuit board to be detected clamping or unclamp；The mechanism for testing includes pedestal 1, lateral separation set on the two of 1 top of pedestal Support plate 11, both ends are loaded on the lateral slide guide bar 12 of two support plates 11, are slidably loaded on slide guide bar 12 and can be along slide guide bar 12 The sliding block 13 of transverse shifting, can vertical movement be installed on the lifters 15 and tension spring (not shown) of sliding block 13, the lifters 15 lower end is passed down through sliding block 13 and installs the probe card 14 for being used for detection circuit board, and the sliding block 13 can be along 12 band of slide guide bar Dynamic probe card 14 is moved between the position above two clamp arm being located above two clamp arm and leave, the tension spring (not shown) Lower end is connected with probe card 14, and upper end is connected with sliding block 13, when being pressed downward compeling lifters 15, probe card can be driven to overcome tension spring Pulling force move down and offset with circuit board below.Specifically, the fixed link 23 is fixedly arranged on pedestal 1,

When work, after circuit board (not shown) is moved between the front positioned at two clamp arm, it is driven by the cylinder its piston Bar stretches out, and pushes drive rod that two clamp arm is driven to be rocked to circuit board clamping by piston rod；Then, sliding block 13 is pushed to drive probe Plate 14 is to the position of circuit board；Then, the pulling force that urgent lifters drive probe card to overcome tension spring is pressed downward to be moved downward to It offsets with the measuring point to be checked of circuit board, the detection of circuit board can be carried out, after the completion of detection, unclamp lifters 13, make probe card Under the pulling force effect of tension spring, the upward reset movement together with lifters waits circuit board detecting next time to work.

In the utility model embodiment, the quantity of slide guide bar 12 at least two, such as have two, three, four or The case where person is more, is as shown in Figure 1 two.The sliding block 13 has the guide through hole (not shown) through its both lateral sides wall, The sliding block is slidably set in slide guide bar 12 by guide through hole, keeps the sliding block 13 laterally past along the slide guide bar 12 It is multiple mobile.Specifically, the quantity of the guide through hole is consistent with the quantity of slide guide bar 12, as shown in Figure 1, the case where being two.

Specifically, the quantity of the tension spring be it is multiple, such as two, three, four or more, in the present embodiment, The tension spring is two, and the both ends of the tension spring are detachably connected with the sliding block 13 and the probe card 14 respectively, described After tension spring uses for a long time and fatigue failure occurs, the easy to disassemble and tension spring that more renews.

Specifically, sliding block 13 offers the vertical guide hole 16 through its upper and lower surface, lifters 15 and vertical 16 phase of guide hole Suitable, the lower end of lifters 15 is passed through and is detachably connected after the vertical guide hole 16 with probe card 14 (such as by screw or card Buckle structure is detachably connected), to replace corresponding probe card when the circuit board of different size need to be detected, to improve this reality With novel versatility, to adapt to the detection demand of different circuit boards, in addition, vertical guide hole 16 can make the vertical of lifters 15 Movement is oriented to, it is ensured that the probe on probe card 14 is uniformly contradicted with circuit board, to guarantee detection accuracy.

Specifically, the piston rod of the cylinder fixed (such as being locked by nut 25) has free bearing 24, the drive rod One end is articulated on free bearing 24, when the piston rod of the cylinder 2 stretches out, drives the drive rod 21 to be moved along, the driving Mobile drive 2 clamp arm 22 of bar 21 do expansion action；When the piston rod of the cylinder 2 retracts, the drive rod is driven 21 move backward, and mobile drive 2 clamp arm 22 of the drive rod 21 tighten movement, are thusly-formed a fixture Opening and clamping process.

Further, the front of the apparent surface of two clamp arm 22 offers the limiting slot 25 through its front bulkhead, After circuit board to be detected is inserted into slot, the piston rod of cylinder 2, which stretches out and passes through drive rod, drives two clamp arm 22 to draw close swing in advance Determine angle, circuit board clamping to be detected can be consolidated, to carry out the probe in detecting work of circuit board.Specifically, the slot of limiting slot Wall is covered with one layer of rubber pad 26, and rubber pad 26 plays insulation and buffer function, with protection circuit plate.When will be electric as cylinder When the clamping of road plate, unclamp circuit board, can grasp by the way that the control switch being electrically connected with cylinder is arranged, and by staff Control switch is realized, or setting sensor is realized to incude.

Further, the top of lifters 15 stretches out vertical guide hole 16 upwards and is connected with handle 17, can be by pressing handle Hand 17 is to push 15 downlink of lifters.Specifically, 17 horizontal size of handle (such as length or width) is greater than vertical guide hole 16, Enter vertical guide hole 16 to avoid handle 17.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model Transformation, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
