Example 1

As shown in fig. 1, a blanking device for a screw heading machine of this embodiment includes a PLC control section, a vibration plate 10 for arranging semi-finished screws in order, a belt conveyor 20 for conveying the semi-finished screws horizontally, a photoelectric sensor 30 for detecting the position of the semi-finished screws, a detection mechanism 40 for detecting whether the semi-finished screws are qualified or not, and a pushing cylinder 50 for removing the semi-finished screws whose detection result is unqualified. The vibration disk 10 is arranged below the discharge end of the screw heading machine. The feeding end of the belt conveyor 20 is connected with the discharging end of the vibration disc 10.

The photoelectric sensor 30, the detection mechanism 40 and the pushing cylinder 50 are sequentially arranged at intervals along the movement direction of the semi-finished screw and are electrically connected with the PLC control part. The PLC control part may be an existing PLC component, which can acquire the detection data returned by the photoelectric sensor 30 and the detection result of the detection mechanism 40 in real time, and control the actions of the detection mechanism 40 and the pushing cylinder 50 according to the position detection data and the heading quality detection result of the semi-finished screw. Since the distance between the photoelectric sensor 30 and the detecting mechanism 40 is fixed, the movement speed of the semi-finished screw is fixed, and thus, the delay time parameter of the action of the detecting mechanism 40 can be written into the PLC. Similarly, because the distance between the detection mechanism 40 and the pushing cylinder 50 is fixed, the movement speed of the semi-finished screw is fixed, and thus, the delay time parameter of the action of the pushing cylinder 50 can be written into the PLC, thereby realizing automatic and accurate control.

Preferably, the photoelectric sensor 30, the detecting mechanism 40 and the pushing cylinder 50 in this embodiment are disposed on the same side of the belt conveyor 20, so as to reduce the occupied area and improve the convenience of operation and maintenance.

The belt conveyor 20 includes a frame, a conveyor belt, a driving roller, a driven roller, and a gear reduction motor for driving the driving roller to rotate. Under the action of the vibration disk 10, the semi-finished screws to be detected are orderly arranged on the conveyor belt at intervals. The vibration plate 10, the belt conveyor 20 and the photoelectric sensor 30 are well known in the art, and will not be described in detail herein.

Preferably, the gear reduction motor is electrically connected with the PLC control part, namely, the PLC control part is used for controlling the start and stop of the gear reduction motor so as to further improve the automation degree of the device. The photoelectric sensor 30 and the pushing cylinder 50 are fixedly arranged on the frame of the belt conveyor 20.

The working principle of this embodiment is as follows:

firstly, under the action of a vibration disc 10, semi-finished screws discharged by a screw heading machine are sequentially arranged on a conveyor belt of a belt conveyor 20 at intervals in order, and when the semi-finished screws on the conveyor belt pass through a photoelectric sensor 30, the photoelectric sensor 30 detects signals and transmits the signals to a PLC control part;

then, the PLC controls the detection mechanism 40 to act according to the position detection data, namely, the detection mechanism 40 detects when the corresponding semi-finished screw reaches the detection range of the detection mechanism 40 according to the preset delay time parameter of the action of the detection mechanism 40;

finally, the PLC controls the pushing cylinder 50 to act/not act according to the detection result of the detection mechanism 40, namely if the detection result is unqualified, the corresponding semi-finished screw acts according to the preset delay time parameter of the pushing cylinder 50 when reaching the action range of the pushing cylinder 50, and the piston rod of the pushing cylinder 50 extends outwards to remove the unqualified semi-finished screw and resets; if the detection result is qualified, the pushing cylinder 50 does not act, and the corresponding semi-finished screw continues to move to blanking.

The screw head quality can be automatically detected in the blanking process, unqualified semi-finished screw after the head is finished is timely screened, namely, the qualified semi-finished screw can enter the subsequent process, the subsequent processing difficulty and the defective product production cost are effectively reduced, and therefore screw processing efficiency, finished product quality and yield are remarkably improved.

Example 2

This embodiment is substantially the same as the main body structure of embodiment 1, except for the improvement of the detection mechanism 40.

As shown in fig. 1, the detection mechanism 40 includes an image recognition module, and a ring light source 41 and an industrial camera 42 electrically connected to the PLC control part. The annular light source 41 is arranged on one side of the industrial camera 42, which is close to the belt conveyor 20, and plays a role in providing observation light and weakening interference of ambient light, so that accuracy and precision of photographing detection are ensured. The industrial camera 42 includes an FA lens 43, and the FA lens 43 is disposed coaxially with the annular light source 41 to further ensure accuracy and precision of photographing detection. The signal input end and the signal output end of the image recognition module are respectively connected with the industrial camera 42 and the PLC control part.

By adopting the technical scheme, the PLC control part controls the annular light source 41 to be started and the industrial camera 42 to photograph according to the position detection data, and receives the detection result transmitted back by the image recognition module. The image recognition module may be a computer equipped with image recognition software for receiving and displaying the image photographed by the industrial camera 42, processing the photographed image, and transmitting the processed result to the PLC control section. The image recognition software part in the computer can be realized by adopting the existing software, and various defective product images can be preset for comparison, and the description is omitted here.

As shown in fig. 1 and 2, the detecting mechanism 40 further includes a base 44, a horizontal support rod 45 and a vertical support rod 46 for adjusting the assembly positions of the ring-shaped light source 41 and the industrial camera 42.

As shown in fig. 1, a push plate 60 is fixedly installed at one end of the piston rod of the pushing cylinder 50 away from the cylinder body. The two ends of the push plate 60 extend outwards to form a material blocking section 61.

By adopting the technical scheme, the contact area between the piston rod of the pushing cylinder 50 and the semi-finished screw can be increased, so that the thrust received by the semi-finished screw is more uniform, and meanwhile, the blocking section 61 can play a role in limiting and guiding the movement of the semi-finished screw, thereby improving the pushing stability.

As shown in fig. 1, a reject collection box 70 used in combination with the pushing cylinder 50 is provided on one side of the belt conveyor 20. A material guiding inclined plate 80 is arranged between the unqualified product collection box 70 and the belt conveyor 20.

By providing the guide sloping plate 80, the movement of the semi-finished screw is limited and guided. That is, when the semi-finished screw whose detection result is failed passes through, the pushing cylinder 50 is operated, and the pushing plate 60 pushes the semi-finished screw onto the guiding inclined plate 80, and then enters the reject collecting box 70.

In the present utility model, the devices and components not described in the structure are all commercially available devices or components.
