Description

Technical Field

[0001] The utility model relates to the technical field of chain detection, in particular to a chain flexibility detection device. Background Art

[0002] In the production process of a chain, multiple chain links are mainly butted end to end, and a plurality of chain fasteners are used to fasten and lock the butted chain links, so as to assemble the chain. During the process of fastening and locking the chain fasteners, when the locking force is too large or there are dust impurities remaining on the chain links, the assembled chain will be knotted, and the flexibility of the knotted part of the chain will be reduced. When using this chain, the knotted part of the chain cannot fit on the sprocket, and in severe cases, there will be tooth hitting and falling off, which poses a great safety hazard. The assembly process of a chainsaw chain is similar to that of an ordinary chain. By setting saw teeth on the chain and driving the chain to rotate at a high speed by a chainsaw, the chain can achieve a cutting function. Therefore, the flexibility detection step of the chainsaw chain is particularly important. Most of the existing chain flexibility detection methods are to manually bend the chain to detect, with too low detection efficiency, and the saw teeth on the chain are easy to cause injuries to the hands of the detection personnel. In view of this, the present utility model is proposed. Content of the Utility Model

[0003] In order to solve the problem of too low efficiency when manually detecting the flexibility of a chain, the present utility model provides a chain flexibility detection device.

Grooves for inserting the connecting buckles are formed on the side surfaces around the detecting tool. When the conveying wheel conveys the chainsaw chain to move intermittently, it drives the chain fasteners to move along the side surface of the detecting tool, and at the same time makes the connecting buckles move in the grooves.

[0019] The following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0020] Please refer to Figure 1 - Figure 2 , the chain flexibility detection device 1 of the present utility model includes a transmission component and a detection component. The transmission component includes a frame 11, a transmission wheel, and a guide wheel 12. The transmission wheel is rotatably connected to the frame 11 to intermittently transmit the chain for movement. The detection component includes a gauge 13, a camera 14, and a detection host. The gauge 13 is rectangular with rounded corners at its four sides. The gauge 13 is attached to and fixed on the frame 11. The guide wheel 12 is rotatably connected to the frame 11 and abuts against the chain to be in contact with at least two adjacent sides of the gauge 13. The camera 14 is arranged on the frame 11 and faces the gauge 13 to capture an image of the chain. The detection host is electrically connected to the camera 14 to perform flexibility detection on the chain image captured by the camera 14 and display the detection result.

[0021] The chain is intermittently transmitted by the transmission wheel, and under the action of the guide wheel 12, the chain is in contact with the gauge 13, so that when the chain is intermittently transmitted, it moves in contact with the gauge 13. By arranging the camera 14 above the gauge 13 and electrically connecting the detection host to the camera 14, the camera 14 captures an image of the chain from above the gauge 13 and transmits the chain image to the detection host, thereby detecting whether the flexibility of the chain meets the standard and displaying the detection result on the detection host for the operator to view.

[0022] By setting rounded corners on the gauge 13 and making the chain contact at least two adjacent sides of the gauge 13 under the action of the guide wheel 12, the chain bends at the rounded corners, so that the camera 14 can capture an image of the chain at the rounded corners, and the detection host detects the distance between the chain and the rounded corners, thereby detecting the flexibility of the chain bending.

[0023] When performing the flexibility detection operation on the chain, the driving wheel drives the chain to move intermittently, and the camera 14 takes an image of the chain during the stationary period of the chain. Subsequently, the detection host detects the chain to determine whether there is a knot in the current position of the chain. When it is detected that the chain does not have a knot, the driving wheel drives the chain to move once again and then stops, and the camera 14 takes an image of the chain again for the detection host to detect. By repeating this cycle, the flexibility of the entire chain can be quickly detected. Compared with the manual detection method, the detection device 1 of the present utility model can improve the efficiency of the flexibility detection of the chain and avoid the situation of injury during manual detection.

[0024] In the above embodiment, the detection host detects the chain image through an image detection algorithm to detect the distance between the chain and the side surface of the inspection tool 13. When it is detected that the distance between the chain and the inspection tool 13 is greater than the preset value, it is determined that the flexibility of the chain is unqualified, and the specific unqualified position is circled on the detection host to facilitate the operator to rework the unqualified chain. Among them, the detection host can be a computer to process the chain image and display the detection result.

[0025] In the embodiment of the present utility model, the chain includes a chainsaw chain 2. The chainsaw chain 2 includes chain links 21, saw teeth 22, chain buckles 23, and connection buckles 24. The chain links 21 are connected end to end through the connection buckles 24. The saw teeth 22 and the connection buckles 24 are both connected between two chain links 21. Grooves for inserting the connection ports are provided on the side surfaces around the inspection tool 13. When the conveyor wheel drives the chainsaw chain 2 to move intermittently, it drives the chain buckle 23 to move along the side surface of the inspection tool 13, and at the same time makes the connection buckle 24 move in the groove.

[0026] By guiding the chainsaw chain 2 through the guide wheel 12, the upper and lower sides of the chainsaw chain 2 are attached to the side surface of the inspection tool 13. By providing grooves on the side surfaces around the inspection tool 13 for the connection buckle 24 to move in, under the intermittent transmission of the driving wheel on the chain, the chainsaw chain 2 moves along the side surface of the inspection tool 13, and the limiting effect of the groove on the connection buckle 24 prevents the chainsaw chain 2 from jumping, thereby avoiding inaccurate chain images taken by the camera 14 and resulting in inaccurate detection results for the chainsaw chain 2.

[0027] In the embodiment of the present utility model, the detection component includes a camera 14 bracket. The camera 14 bracket is L-shaped and one end is fixed to the frame 11, and the other end faces directly above the inspection tool 13 for the camera 14 to be connected, so that the camera 14 takes a chain image downward from above the inspection tool 13 to facilitate the detection host to detect the chain image to determine whether there is a knot in the chain.

[0028] In an embodiment of the present utility model, the detection assembly includes a camera 14 bracket. The camera 14 bracket is a gantry. Both sides of the camera 14 bracket are located on both sides of the inspection fixture 13 and are slidably connected to the frame 11. The camera 14 is slidably connected to the camera 14 bracket to detect the chain at different positions of the inspection fixture 13. During the process of the chain moving around the inspection fixture 13, the position of the gantry and the position of the camera 14 on the gantry can be adjusted to enable the camera 14 to capture chain images at different positions of the inspection fixture 13, thereby detecting the spacing between the chain and the inspection fixture 13 at different angles and improving the diversity of chain detection.

[0029] In an embodiment of the present utility model, slide rails are provided on the frame 11 on both sides of the inspection fixture 13, and pulleys slidably connected to the slide rails are provided on the camera 14 bracket. When it is necessary to adjust the position of the camera 14 bracket, the camera 14 bracket is pushed to make the pulley slide along the slide rail and adjust the position of the camera 14 bracket, thereby adjusting the position of the camera 14 to enable the camera 14 to take pictures of the chain at different positions of the inspection fixture 13, thereby detecting the spacing between the chain and the inspection fixture 13 at different angles and improving the diversity of chain detection.

[0030] In an embodiment of the present utility model, a camera 14 base is connected to the camera 14, and a chute for the camera 14 base to be slidably connected is provided on the camera 14 bracket. When it is necessary to adjust the position of the camera 14 bracket, the camera 14 is pushed to make the camera 14 base slide along the chute and adjust the position of the camera 14 to enable the camera 14 to take pictures of the chain at different positions of the inspection fixture 13, thereby detecting the spacing between the chain and the inspection fixture 13 at different angles and improving the diversity of chain detection.

[0031] In an embodiment of the present utility model, the width dimension range of the inspection fixture 13 is 70 mm - 90 mm, and the fillet dimension range around the inspection fixture 13 is 12 mm - 25 mm, so that when the conveyor wheel conveys the chain to move intermittently, the chain is driven to move along the side surface of the inspection fixture 13, and the chain passes through the fillets around the inspection fixture 13, so that the chain is bent at least twice. Then, the camera 14 detects the spacing between the chain and the inspection fixture 13 at different positions of the inspection fixture 13, and the detection host judges whether the chain is knotted according to the spacing between the chain and the inspection fixture 13, thereby improving the detection accuracy of the chain.

[0032] In an embodiment of the present utility model, two guide wheels 12 are provided. The two guide wheels 12 are respectively rotatably connected to the frame 11 on both sides of the inspection fixture 13 and abut against the chain to be attached to three adjacent side surfaces of the inspection fixture 13. Since the fillet dimensions on both sides of the spacing are different, when the chain is attached to three adjacent side surfaces of the inspection fixture 13, the chain can be bent to different degrees. Then, when the camera 14 captures the chain image, the detection host can detect the flexibility of the chain when it is bent to different degrees, thereby improving the diversity of chain detection.

Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.
