And the number of the guide wheels 123 is multiple. The multiple guide wheels 123 cooperate with the driving idler 122 to determine the moving path of the chain on the workbench 110.

[0039] Reference Figures 1 - 3 , the cleaning member 130 includes at least two air knives 131 arranged oppositely. The two air knives 131 are respectively located on both sides of the chain. By arranging the opposite air knives 131, it is used to blow and clean both sides of the chain to avoid impurities remaining on the chain and affecting subsequent operations.

[0040] Of course, in other embodiments of the present invention, the number of the air knives 131 can also be one, three, four, etc. The specific number of the air knives 131 is not limited.

[0041] And, in order to enable the air knives 131 to blow and clean the chain directly, the workbench 110 can be provided with a first groove 111, and both the two air knives 131 are installed in the first groove 111.

[0042] Reference Figures 1 - 3, in order to detect different sides of the chain, the image acquisition component 140 can include a first acquisition component 141, a second acquisition component 142, and a third acquisition component 143. The first acquisition component 141 is arranged on the upper side of the chain, the second acquisition component 142 is arranged on the lower side of the chain, and the third acquisition component 143 is arranged beside the chain. It should be noted that the side beside the chain can be understood as the left side or the right side of the chain.

[0043] Specifically, the first acquisition component 141 includes a first support rod 1411, a first light source 1412, and a first camera 1413. The first support rod 1411 is connected to the workbench 110 and extends towards the upper side of the workbench 110. The first light source 1412 and the first camera 1413 are both arranged on the first support rod 1411. The first support rod 1411 is used to support the first light source 1412 and the first camera 1413, and the first light source 1412 is used to provide illumination so that the first camera 1413 can obtain chain image information with sufficient brightness.

[0044] The second acquisition component 142 includes a second support rod 1421, a second light source 1422, and a second camera 1423. The second support rod 1421 is connected to the workbench 110 and extends towards the lower side of the workbench 110. The second light source 1422 and the second camera 1423 are both arranged on the second support rod 1421. The second support rod 1421 is used to support the second light source 1422 and the second camera 1423, and the second light source 1422 is used to provide illumination so that the second camera 1423 can obtain chain image information with sufficient brightness.

[0045] In addition, in order to avoid occlusion during image acquisition of the second camera, the workbench 110 can be provided with an acquisition hole 113, and the acquisition hole 113 is arranged corresponding to the second camera 1423.

[0046] The third acquisition component 143 includes a third camera 1431 and a third light source 1432. The third camera 1431 and the third light source 1432 are both arranged beside the chain. In this embodiment, the third camera 1431 and the third light source 1432 are respectively located on the left and right sides of the chain, and the third light source 1432 provides illumination so that the third camera 1431 can obtain chain image information with sufficient brightness.

[0047] Moreover, in order to make the third camera 1431, the third light source 1432 and the chain relatively flush, the workbench 110 can be provided with a second groove 112, and both the third camera 1431 and the third light source 1432 are accommodated in the second groove 112.

[0048] It should be noted that each camera is used to accurately measure the roller diameter, chain plate thickness, inner width of inner link, inner width of outer link, and the presence or absence of sleeves of the chain by collecting image information.

[0049] ReferenceFigures 1 - 3 The chain detection device 100 further includes a brake member 150, which is sequentially arranged with the driving member 120 along the moving direction of the chain, and an image acquisition member 140 is arranged between the brake member 150 and the driving member 120. Specifically, a third acquisition member 143 is arranged between the brake member 150 and the driving member 120.

[0050] In the working state, the driving member 120 is used to pull the chain to move, and the braking member 150 is used to brake the chain. During the braking action, the chain portion between the two can be tensioned and stretched, thereby facilitating better image acquisition and making the detection effect more accurate.

[0051] refer to Figures 1 - 3 The brake member 150 includes a brake 151 and a brake wheel 152 which are connected in a transmission manner. The brake 151 and the brake wheel 152 are both arranged on the workbench 110, and the brake wheel 152 cooperates with the chain. Specifically, the brake 151 is a magnetic powder brake 151. The brake 151 generates a braking force, which drives the brake wheel 152 to move, and the cooperation between the brake wheel 152 and the chain produces a braking effect on the chain.

[0052] In addition, the brake component 150 also includes a dividing plate 153 and a sensor 154. The dividing plate 153 is transmission-connected to the brake wheel 152. The dividing plate 153 is provided with at least two slots 1531 along the circumferential direction. The sensor 154 is disposed on the workbench 110 and is used to output information representing the motion state of the slots 1531. The sensor 154 communicates with the image acquisition component 140.

[0053] It is worth noting that the brake wheel 152 can specifically be a sprocket or other structure that can generate braking resistance to the chain, and its specific structural form is not limited.

[0054] In this embodiment, the number of notches 1531 is twenty, and the twenty notches 1531 are evenly arranged along the axial direction of the indexing plate 153, so that the central angle between two adjacent notches 1531 is 18°. The sensor 154 is a photoelectric switch and has a U-shaped structure. The indexing plate 153 extends into the inner side of the U-shape of the photoelectric switch. The photoelectric switch can obtain the rotation rate of the indexing plate 153, and then generate a pulse signal. The photoelectric switch can transmit the pulse signal to the first camera 1413, the second camera 1423 and the third camera 1431, so that the operation time and interval of each camera are more accurate.

[0055] Of course, in other embodiments of the present invention, the number of the slots 1531 can also be three, nine, ten, etc., and there is no limitation on the specific number of the slots 1531. Of course, the number of the slots 1531 can also be related to the number of sprocket teeth of the brake wheel 152. Generally, the number of the slots 1531 is half of the number of sprocket teeth.

[0056] Reference Figures 1 - 3 , in order to make the movement of the chain on the workbench 110 more regular, the chain detection device 100 may further include a limit block 160, which is arranged on the workbench 110 and used to abut against the chain. Moreover, in addition to limiting, one end of the limit block 160 can rotate around a fulcrum to facilitate the placement of the chain.

[0057] In this embodiment, the limit block 160 can be an arc-shaped structure or a cuboid structure, which can respectively abut and limit the arc segment and the straight segment of the chain, thereby preventing the chain from being easily bent and deformed during movement.

[0058] It should be noted that the chain detection device 100 further includes a controller, which can be an industrial computer, a single-chip microcomputer of the STM-32 series, or a PLC. The controller can be a separate module in the device or can be arranged in a certain camera. The controller communicates with the sensor 154 and each camera at the same time. The camera is used to transmit the acquired image information to the controller, and the controller processes, identifies, measures, and determines the image. If unqualified products appear, they are stored by the controller.

[0059] Of course, the chain detection device 100 can also include an alarm, which can be a speaker, a color-changing lamp, or a multi-color warning lamp. When the chain has a detection failure, the controller sends a signal to the alarm, and the speaker or the color-changing lamp gives an alarm prompt to the staff so as to process the defective products in time.
