For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0040] The embodiment of the present invention provides a belt conveyor foreign body removal device, such as Figure 1 to Figure 7 As shown, it includes a conveyor belt 101, and a first visual unit 103, an adjustment mechanism 200, a second visual unit 104 and a clamping mechanism 300 are fixedly installed in sequence on the side of the conveyor belt 101 along its conveying direction through supporting legs 102.

[0041] The first visual unit 103 and the second visual unit 104 have the same structure. Figure 5 As shown, the top of the support leg 102 is fixed to the middle of the mounting seat 105 through a connecting rod, and a camera 106 is fixedly installed on the side of the mounting seat 105 close to the upstream of the conveyor belt 101. The camera 106 is used to identify foreign objects in the transported objects on the conveyor belt 101. A rangefinder 107 is fixedly installed on the side of the mounting seat 105 close to the downstream of the conveyor belt 101. The rangefinder 107 is used to measure the height value of the identified foreign objects.

[0042] The adjustment mechanism 200 and the clamping mechanism 300 are respectively fixedly mounted on the support leg 102 through the displacement mechanism 400. Figure 2 As shown, the displacement mechanism 400 includes a first guide rail 401, a third motor 402, a first sliding block 403, a second guide rail 404, a fourth motor 405, and a second sliding block 406. The leg 102 is fixed to the first guide rail 401, the third motor 402 is fixedly installed at the end of the first guide rail 401, the output end of the third motor 402 is drivingly connected to the first sliding block 403, the first sliding block 403 is slidably configured in the first guide rail 401, the first sliding block 403 is fixed to the second guide rail 404, the fourth motor 405 is fixedly installed at the end of the second guide rail 404, the output end of the fourth motor 405 is drivingly connected to the second sliding block 406, and the second sliding block 406 is used to install the adjustment mechanism 200 or the clamping mechanism 300.

[0043] Among them, the third motor 402 can be driven and connected to the first sliding block 403 through a screw, the output end of the third motor 402 is coaxially fixed with the screw, and the screw is threadedly connected to the first sliding block 403, thereby realizing the third motor 402 driving the first sliding block 403 to slide back and forth along the first guide rail 401.

[0044] Of course, the third motor 402 can also be a linear motor, and the output end of the third motor 402 is directly fixed to the first sliding block 403 , thereby ensuring that the third motor 402 can drive the first sliding block 403 to slide back and forth along the length direction of the first guide rail 401 .

[0045] The driving connection mode between the fourth motor 405 and the second sliding block 406 is the same as the driving connection mode between the third motor 402 and the first sliding block 403 .

[0046] Among them, the first guide rail 401 is horizontally arranged perpendicular to the length direction of the conveyor belt 101, and the second guide rail 404 is vertically arranged, so that the reciprocating sliding of the first sliding block 403 and the reciprocating sliding of the second sliding block 406 can realize the reciprocating sliding of the adjustment mechanism 200 and the clamping mechanism 300 along the direction perpendicular to the conveyor belt 101 and the reciprocating sliding in the vertical direction respectively.

[0047] For further explanation of the present invention, see Figure 3 , 4 The adjustment mechanism 200 includes a turntable 201, which is fixed to the second sliding block 406. A first motor 202 is fixedly installed on the turntable 201. The output end of the first motor 202 is coaxially fixed with the worm 203. The worm 203 is meshed with the worm wheel 204. The worm wheel 204 is coaxially fixed with the rotating shaft 205. The rotating shaft 205 is rotatably installed on the turntable 201, and the rotating shaft 205 is coaxially fixed with the mounting plate 206.

[0048] The bottom of the mounting plate 206 is fixedly connected to the first end of the support shaft 207, the second end of the support shaft 207 is hinged to the middle of the adjustment plate 208, one side of the adjustment plate 208 is hinged to the first end of the electric telescopic rod 209, and the second end of the electric telescopic rod 209 is hinged to the lower surface of the mounting plate 206.

[0049] A second motor 210 is fixedly installed at one end of the adjustment plate 208 away from the electric telescopic rod 209. The output end of the second motor 210 passes through the adjustment plate 208 and is coaxially fixed to the first pulley 211. The first pulley 211 is driven by a second pulley 213 through a plurality of transmission belts 212. The second pulley 213 is rotatably installed at one end of the adjustment plate 208 close to the electric telescopic rod 209.

[0050] An air pipe 214 is fixedly installed on one side of the mounting plate 206 close to the electric telescopic rod 209. The first end of the air pipe 214 is fixedly installed on the adjusting plate 208, and the second end of the air pipe 214 is connected to the high-pressure air pipe. The high-pressure gas transported in the air pipe 214 can disperse the materials near the foreign object, making it convenient to observe the foreign object and measure its height value.

[0051] The present invention, through the above structure, can achieve the evacuation of materials near the foreign object in cooperation with the detection of the first visual unit 103, and adjust the position and orientation of the foreign object through the adjustment mechanism 200, so as to facilitate further observation of the foreign object and measurement of the height value.

[0052] The implementation process of the above function is as follows: when the camera 106 in the first visual unit 103 recognizes a foreign object on the conveyor belt 101, the height value of the foreign object is first calculated by the rangefinder 107, and then the displacement mechanism 400 adjusts the position of the adjustment mechanism 200 according to the observed position of the foreign object. First, the adjustment mechanism 200 is located directly above the foreign object. At this time, the first motor 202 drives the worm 203 to rotate, and drives the worm wheel 204, the rotating shaft 205 and the mounting plate 206 to rotate circumferentially through the meshing relationship between the worm 203 and the worm wheel 204. The material near the foreign object is evacuated through the air pipe 214 installed at the bottom of the mounting plate 206, making the foreign object more prominent, facilitating the second observation and judgment of the foreign object, and after the material near the foreign object is evacuated, it is convenient to grasp and remove the foreign object later.

[0053] After the above actions are completed, the adjustment mechanism 200 is further driven downward by the displacement mechanism 400 and adjusted to the point where the lower surface of the transmission belt 212 contacts the foreign object. At this time, the second motor 210 is started and the transmission belt 212 is driven to rotate by the first pulley 211. The position and orientation of the foreign object are adjusted by the friction between the transmission belt 212 and the foreign object, thereby realizing multi-angle and multi-directional observation and judgment of the foreign object, thereby increasing the accuracy of foreign object detection.

[0054] In the above process, when the adjustment mechanism 200 is adjusted downward by the displacement mechanism 400, in order to facilitate the adjustment of foreign objects, the adjustment plate 208 can be tilted by adjusting the extension and retraction of the electric telescopic rod 209, so that the position where the transmission belt 212 contacts the foreign object can be more convenient for adjusting the foreign object.

[0055] Among them, the structure composed of the support shaft 207, the adjustment plate 208, the electric telescopic rod 209, and the air pipe 214 is symmetrically distributed in two groups about the center of the installation plate 206. This structure makes the adjustment mechanism 200 more stable during the process of completing the above-mentioned actions.

[0056] For further explanation of the present invention, see Figure 6 , 7The clamping mechanism 300 includes a mounting plate 301, on which the mounting plate 301 is fixedly mounted, and on which the electric cylinder 303 is mounted, a first mounting frame 302 is mounted at the bottom of the mounting plate 301, on which the first end of the second mounting frame 304 is fixedly mounted, and in which the second mounting frame 304 is provided a driving rod 305 which reciprocates along its height direction, and the middle part of the driving rod 305 is fixed to the output end of the electric cylinder 303, and on both ends of the driving rod 305 are respectively fixedly mounted connecting seats 306, on which the first end of the connecting rod 307 is rotatably mounted, and the second end of the connecting rod 307 is rotatably mounted on the sleeve ring 308, and the sleeve ring 308 is sleeved on the sleeve rod 309 and can reciprocate along its length direction, and the first end of the sleeve rod 309 is hinged to the second end of the second mounting frame 304, and the second end of the sleeve rod 309 is fixed to the clamping plate 310.

[0057] The structure consisting of the connecting seat 306, the connecting rod 307, the ring 308, the sleeve rod 309, and the clamping plate 310 is symmetrically distributed in two groups about the center of the second mounting frame 304, so that the clamping plates 310 in the two groups of structures can be close to or away from each other to achieve the clamping or release of foreign objects.

[0058] The present invention further detects whether the foreign object is accurate after position adjustment by configuring the second visual unit 104 between the adjustment mechanism 200 and the clamping mechanism 300. When it is determined that the foreign object is accurate, the height value of the foreign object at this time is calculated by the second visual unit 104, so that the position and height adjustment of the clamping mechanism 300 can be achieved through the displacement mechanism 400, which facilitates the clamping and removal of the foreign object.

[0059] During the process of adjusting the position of the clamping mechanism 300, the expansion and contraction of the output end of the electric cylinder 303 can cooperate to achieve the clamping and removal of foreign objects. The expansion and contraction of the electric cylinder 303 can adjust the position of the driving rod 305, and drive the connecting rod 307 and the ring 308 to run synchronously through the connecting seat 306. When the driving rod 305 moves in the direction close to the electric cylinder 303, the ring 308 drives the sleeve rod 309 to rotate around the hinge axis of its first end. At this time, the two clamping plates 310 are separated from each other. Conversely, when the driving rod 305 moves in the direction away from the electric cylinder 303, the two clamping plates 310 approach each other. By the two clamping plates 310 approaching or moving away from each other, the clamping and release of foreign objects can be smoothly achieved.

[0060] In order to facilitate the mutual coordination between various mechanisms, the present invention is also provided with a controller 500, which is respectively connected to the first visual unit 103, the second visual unit 104, the first motor 202, the electric telescopic rod 209, the second motor 210, the electric cylinder 303, the second guide rail 404, and the fourth motor 405 for signal collection and processing of information, and issuing instructions to realize the normal operation of various mechanisms.

[0061] Through the above-mentioned structure and control method, foreign objects on the conveyor belt 101 can be successfully identified, and the clamping mechanism 300 can be driven to successfully clamp and remove the foreign objects. This method improves the accuracy of foreign object identification, avoids problems such as incomplete foreign object removal due to failure to identify foreign objects, or material waste due to incorrect foreign object identification.

[0062] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention.
