[0025] Example

[0026] In order to solve the defects of manual fastener detection in the prior art, reference Figure 1 and Figure 2 As shown, the utility model discloses a fastener height detection device, comprising:

[0027] A vibrating plate 10, the output end of which is connected to a feeding channel 11;

[0028] A testing machine 20, a fastener temporary placement groove 21 is provided on one side of the testing machine, a feeding channel is connected to the fastener, a side-opened material discharge groove 23 is provided on the other side of the testing machine, and a fastener slot 22 is provided between the fastener temporary placement groove and the material discharge groove;

[0029] A material discharge line 30, the material discharge line is arranged inside the material discharge chute;

[0030] A detection mechanism 40, the detection mechanism includes a contact detection probe 42 and a rotary pressing cylinder 41, the rotary pressing cylinder is arranged on a detection machine corresponding to the outside of the fastener slot, and the contact detection probe is arranged on a detection machine corresponding to the fastener slot and the rotary pressing cylinder;

[0031] The loading and unloading material handling mechanism 50 includes a truss 51, two linear drive modules 52, two lifting drive modules 53 and two pneumatic clamps 54. The two linear drive modules are arranged on the crossbeam of the truss, the two lifting drive modules are respectively connected to the two linear drive modules, and the two pneumatic clamps are respectively connected to the two lifting modules;

[0032] The defective product recovery trough 60 is arranged above the middle of the material discharge trough.

[0033] Here, the contact detection probe is specifically described. Before setting the contact detection probe, a fastener of standard length should be placed in the fastener slot, and then the contact detection probe is installed on the detection machine and the measuring end of the contact detection probe is in contact with the pressing block of the rotating downward pressure cylinder. At this time, the value formed by the measuring end of the contact detection probe contacting the pressing block of the rotating downward pressure cylinder is the reference value.

[0034] If the reference value is 2mm, when the value formed by the measuring end of the contact detection probe contacting the pressing block of the rotating pressing cylinder is 0mm, then the length of the fastener is the standard fastener size plus 2mm;

[0035] When the value formed by the measuring end of the contact detection probe contacting the pressing block of the rotating pressing cylinder is 4mm, the length of the fastener is the standard fastener size minus 2mm;

[0036] After the inspection of a fastener is completed, the value of the contact inspection probe will return to the reference value.

[0037] In one specific scheme, the inspection machine is equipped with a guide ramp 80 at the conveying end of the unloading conveyor line, and a qualified product recovery trough 90 is placed under the guide ramp. The qualified fasteners are unloaded by the unloading conveyor line and recovered by the qualified product recovery trough after passing the guide ramp.

[0038] In one specific solution, the two linear drive modules are rodless cylinders, and the two lifting drive modules are respectively fixed on the slides of the two rodless cylinders. Driven by the two rodless cylinders, the two lifting drive modules can move horizontally on the crossbeam of the truss.

[0039] In one of the specific solutions, the two lifting drive modules are both pneumatic slides, and the two pneumatic grippers are respectively fixed on the slides of the two pneumatic slides. Driven by the two pneumatic slides, the two pneumatic grippers can perform lifting movements.

[0040] In order to ensure that the pneumatic clamp can smoothly grasp the fastener, the two clamping jaws 541 of each pneumatic clamp of the utility model are provided with grooves 5411 adapted to the head of the fastener on the clamping surface.

[0041] In one of the specific schemes, a stand 70 is arranged above the middle of the material discharge trough, and a positioning groove 71 is opened on the table top of the stand. The unqualified product recovery trough is placed in the positioning groove, which can not only ensure the positioning of the unqualified product recovery trough, but also facilitate the operator to take and place.

[0042] In summary, the specific operation process of the utility model is as follows:

[0043] In the first step, the vibration plate vibrates and transports the fasteners to be fastened through the feeding channel to the fastener temporary storage groove;

[0044] In the second step, one of the linear drive modules first drives the lifting drive module to the top of the fastener temporary placement slot. After it is in place, the lifting drive module drives the pneumatic gripper to descend, and the pneumatic gripper grabs the fastener (after grabbing the fastener, the lifting drive module drives the pneumatic gripper to reset). Then, the linear drive module drives the lifting drive module to the top of the fastener slot. After it is in place, the lifting drive module drives the pneumatic gripper to descend, and the pneumatic gripper places the grabbed fastener into the fastener slot.

[0045] The third step is to rotate the pressing cylinder to drive the pressing block to rotate and make the pressing block press the fastener. When the contact detection probe contacts the pressing block of the rotating pressing cylinder, it can quickly detect whether the fastener is qualified (after the contact detection probe completes the detection, the rotating pressing cylinder drives the pressing block to reset);

[0046] In the fourth step, another linear drive module drives the lifting drive module to the top of the fastener slot. After it is in place, the lifting drive module drives the pneumatic gripper to descend to clamp the inspected fastener (after the pneumatic gripper clamps the fastener, the lifting drive module drives the pneumatic gripper to reset), and according to the detection results of the contact detection probe, the linear drive module drives the lifting drive module to the unload assembly line or to the unqualified recovery tank. When the qualified fasteners are on the unload assembly line, the unload assembly line moves with the fasteners and passes through the guide ramp to the qualified product recovery tank.
