Description

Technical Field

[0001] The present invention relates to a chain buckling defect detection system and a detection method. Background Art

[0002] At present, most detections of chain buckling defects rely on manual visual inspection. That is, the inspector moves the chain by hand on the flat workbench to check whether there is any jamming in the chain links, so as to judge whether there is a buckling defect in the chain.

[0003] This detection method has great uncertainties. During actual operation, it cannot ensure that each chain has been effectively moved, so there is a risk of missed detection. At the same time, due to manual detection, there are individual sensory differences, resulting in risks of missed detection and misjudgment. In addition, due to factors such as attention and fatigue during manual detection, there is also a great risk of missed detection. Moreover, manual detection cannot effectively record the specific physical quantities of each chain, and data traceability cannot be achieved. Summary of the Invention

[0004] The primary technical problem to be solved by the present invention is to provide a chain buckling defect detection system that can automatically, stably and efficiently detect whether there is a buckling defect in a chain according to the above-mentioned prior art.

[0005] The further technical problem to be solved by the present invention is to provide a detection method for a chain buckling defect detection system that can automatically and efficiently detect whether there is a buckling defect in a chain according to the above-mentioned prior art.

[0006] The technical solution adopted by the present invention to solve the above primary technical problem is as follows: A chain buckling defect detection system, characterized by comprising a driving wheel, a driven wheel, a driving motor, a torque sensor and a detection processor. The chain to be detected is drivingly connected to the driving wheel and the driven wheel. The driving wheel is connected to the driving motor and driven by the driving motor to rotate. The torque sensor is arranged on the driving shaft between the driving motor and the driving wheel. The torque sensor is electrically connected to the detection processor. When the driving motor drives the driving wheel to rotate, the torque sensor real-time monitors the torque value on the driving shaft. The detection processor identifies whether there is a buckling defect in the chain to be detected according to the torque value detected by the torque sensor in real time.

[0007] As an improvement, the detection processor can identify the chain link where the buckling defect exists in the chain according to the torque value detected by the torque sensor in real time.

[0008] As a further improvement, the driven wheel is installed on a slider and can slide along the central connection line direction of the driving wheel and the driven wheel, so that chains with different length dimensions can be detected.

[0009] Preferably, the slider is connected to a driven wheel adjusting cylinder, so that the driven wheel can slide on the slider.

[0010] Further improvement, the present invention further includes an inkjet printer, which can inkjet mark the chain with buckling defects.

[0011] Further improvement, a blanking push plate is provided at the rear side of the driving wheel. The blanking push plate is connected to a blanking pushing air cylinder. After the chain detection is completed, the blanking pushing air cylinder is started. The blanking push plate moves under the push of the blanking pushing air cylinder, and then pushes the chain to make the chain disengage from the driving wheel and the driven wheel.

[0012] Further improvement, the driven wheel is arranged below the driving wheel, and a blanking conveyor belt is further provided below the driven wheel. The chain after the detection is completed can directly fall into the blanking conveyor belt.

[0013] Further improvement, a qualified product outlet and a non - qualified product outlet are provided on one side of the blanking conveyor belt.

[0014] Further improvement, the present invention further includes a camera device for detecting the shape defects of the chain to be measured. The camera device is electrically connected to the detection processor. The detection processor can identify whether there are defects in the shape of the chain to be measured according to the images taken by the camera device.

[0015] Preferably, the camera device includes a front camera, a back camera and a side camera. The front camera is connected to a transverse movement mechanism and can reciprocate under the drive of the transverse movement mechanism.

[0016] The technical solution adopted by the present invention to solve the above - mentioned further technical problems is as follows: a detection method for a chain buckling defect detection system with the above - mentioned structure, characterized in that: the chain to be measured is sleeved on the driving wheel and the driven wheel and meshed with the driving wheel and the driven wheel. The driving motor is turned on. After the rotational speeds and operations of the chain to be measured, the driving wheel and the driven wheel are stable, the acquisition data of the torque sensor is collected. After at least one complete cycle of rotation of the chain to be measured, the driving motor is turned off. The detection processor analyzes the torque data collected by the torque sensor. If the torque data of the collected data exceeds the preset maximum value, it is determined that the chain to be measured is a defective product with buckling; if the torque data of the collected data exceeds the preset minimum value, it is also determined that the chain to be measured is a defective product with buckling; if during the process of one complete cycle of rotation of the chain to be measured, the fluctuation value of the collected torque data exceeds the set fluctuation range, it is also determined that the chain to be measured is a defective product with buckling; if during the process of one complete cycle of rotation of the chain to be measured, abnormal fluctuations in the collected torque data that do not match the number of chain links occur, it is also determined that the chain to be measured is a defective product with buckling.

[0017] Compared with the prior art, the advantages of the present invention are as follows: it can realize the detection of actual physical quantities during chain buckling, and has very high consistency and stability, avoiding the missed - detection defects caused by manual detection.

[0021] As Figure 1 and Figure 2 shown, the chain buckling defect detection system includes a frame 1. The frame 1 may include a flat desktop and a bracket provided on the flat desktop. A driving wheel 2, a driven wheel 3, a driving motor 4, a torque sensor 5, a display screen 6, and a chassis 7 are provided on the frame 1. A data collector, a detection processor, and a memory are provided in the chassis 7. The chain 8 to be measured is meshed and connected with the driving wheel 2 and the driven wheel 3. The driving wheel 2 is connected to the driving motor 4 and driven to rotate by the driving motor 4. The torque sensor 5 is disposed on the driving shaft between the driving motor 4 and the driving wheel 2. The torque sensor 5 is electrically connected to the detection processor through the data collector. When the driving motor 4 drives the driving wheel to rotate, the torque sensor 5 monitors the torque value on the driving shaft in real time, and sends the detected torque value to the detection processor through the data collector. The detection processor identifies whether there is a buckling defect in the chain to be measured according to the torque value collected by the data collector. At the same time, the data collector also sends the collected torque value to the memory for storage for later traceability and inspection. In addition, the detection processor can also identify the link where the buckling defect exists in the chain according to the torque value detected by the torque sensor in real time.

[0022] In this embodiment, the driven wheel 3 is disposed below the driving wheel 2; the driven wheel 3 is installed on a slider 10, and the slider 10 is connected to a driven wheel adjusting cylinder 11, so that the driven wheel can slide on the slider along the center connection line direction of the driving wheel and the driven wheel; a blanking push plate 11 is provided at the rear side of the driving wheel 2, and the blanking push plate 11 is connected to a blanking pushing cylinder 12; a blanking conveyor belt 13 is further provided below the driven wheel 3, and a qualified product outlet 131 and an unqualified product outlet 132 are provided on one side of the blanking conveyor belt 13.

[0023] The support 1 is also provided with a camera device for detecting the shape defects of the chain to be measured. The camera device is electrically connected to the detection processor, and the detection processor can identify whether there are defects in the shape of the chain to be measured according to the images captured by the camera device. In this embodiment, the camera device includes a front camera 14 arranged on the front side of the chain 8 to be measured and the driving wheel 2, a rear camera 15 arranged on the rear side of the chain 8 to be measured and the driving wheel 2, and a side camera 16 arranged on the side of the chain 8 to be measured and the driving wheel 2. The front camera 14 is connected to the transverse movement mechanism 17 and can reciprocate under the drive of the transverse movement mechanism 17. A coding device 18 is arranged on one side of the blanking conveyor belt 13, and the coding device 18 can code and mark the chains with buckling defects.

[0024] After the equipment is started, the chain to be measured is manually hung on the driving wheel and the driven wheel and meshed with the driving wheel and the driven wheel. After the chain to be measured is installed in place, the front camera 14 moves to the detection position under the drive of the transverse movement mechanism 17. The detection position is located directly in front of the chain 8 to be measured and the driving wheel 2. At the same time, the driven wheel adjusting cylinder 11 is started to lower the driven wheel 3 to tension the chain to be measured. Then the driving motor is turned on. After the rotational speed and operation of the chain to be measured, the driving wheel and the driven wheel are stable, the acquisition data of the torque sensor is collected. After at least one complete cycle of rotation of the chain to be measured, the driving motor is turned off. The detection processor analyzes the torque data collected by the torque sensor. If the torque data of the collected data exceeds the preset maximum value, it is determined that the chain to be measured is a defective product with buckling; if the torque data of the collected data exceeds the preset minimum value, it is also determined that the chain to be measured is a defective product with buckling; if during the process of one complete cycle of rotation of the chain to be measured, the fluctuation value of the collected torque data exceeds the set fluctuation range, it is also determined that the chain to be measured is a defective product with buckling; if during the process of one complete cycle of rotation of the chain to be measured, the collected torque data shows abnormal fluctuations that do not match the number of chain links, it is also determined that the chain to be measured is a defective product with buckling. At the same time, according to the position of the chain where the buckling value exceeds the preset maximum value or the preset minimum value or the fluctuation value in the torque data, it is the link in the chain where the buckling defect exists.
