[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner only, and therefore only show the components related to the present invention, and directions and references (e.g., up, down, left, right, etc.) may only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not to be taken in a limiting sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0019] Embodiment 1, as Figure 1 and Figure 2 As shown, a magnetic suction conveying device comprises a lifting mechanism 1 and a carrying mechanism 2 connected to the output end of the lifting mechanism 1; The transport mechanism 2 includes two brackets 201 arranged opposite to each other, a steel cable 202 is connected between the two brackets 201, a conveying rod 203 is mounted on the steel cable 202, and the conveying rod 203 is provided with a conveying wheel 204 for mounting it on the steel cable 202 and driving the conveying rod 203 to move along the steel cable 202, and a clamping wheel 205 which is lifted and arranged below the conveying wheel 204 and is used to cooperate with the conveying wheel 204 to clamp the steel cable 202. The outer peripheral walls of the conveying wheel 204 and the clamping wheel 205 both have recesses for the steel cable 202 to be embedded. When the conveying rod 203 is on the steel cable 202, it is driven by the conveying wheel 204 to move along the steel cable 202.

[0020] The lifting mechanism 1 includes two hydraulic rods 101, which correspond to two brackets 201 one by one and the output end of each hydraulic rod 101 is connected to the corresponding bracket 201; when the object 3 needs to be transported, the hydraulic rod 101 is started, and the hydraulic rod 101 can drive the carrying mechanism 2 below it to rise and fall synchronously.

[0021] The top of the transmission rod 203 is rotatably connected to a magnetic rod 206, which is internally installed with an electromagnet. The bottom of the transmission rod 203 is mounted with an object 3, which can be a cargo or a scanner. The scanner can be used to monitor the assembly line. Each bracket 201 is provided with a magnetic attraction portion, which includes an attraction section 2011 that generates attraction with the magnetic rod 206 and a holding section 2012 for mounting the magnetic rod 206 attracted with the attraction section 2011 on the bracket 201. A magnet is embedded in the attraction section 2011. When the magnetic rod 206 and the suction section 2011 are attracted to each other, the suction section 2011 and the supporting section 2012 jointly support the transmission rod 203. When the magnetic rod 206 and the suction section 2011 repel each other, the magnetic rod 206 rotates away from the bracket 201. After the transmission rod 203 loses its supporting force, it is mounted on the steel cable 202 and the object 3 is transmitted.

[0022] In the initial state, the magnetic rod 206 is attracted to the suction section 2011 of one of the brackets 201, and the suction section 2011 and the holding section 2012 work together to fix the magnetic rod 206, thereby holding the transmission rod 203, so as to reduce the force acting on the steel cable 202, thereby increasing the service life of the steel cable 202; When the device is working, the lifting mechanism 1 first adjusts the height of the transport mechanism 2 so that the device body is at the working height, and then the magnetic rod 206 changes its polarity and repels the suction section 2011 of the bracket 201. At this time, the magnetic rod 206 is pushed away, and while it rotates to disengage from the bracket 201, the transmission rod 203 loses its support and is then mounted on the steel cable 202. The clamping wheel 205 moves up and cooperates with the transmission wheel 204 to clamp the steel cable 202. Then the transmission wheel 204 rotates to drive the transmission rod 203 and the object 3 thereon to move along the steel cable 202 to the desired position. The lifting mechanism 1 drives the transport mechanism 2 to move downward, so that the object 3 reaches the specified position.

[0023] like Figure 5 As shown, the magnetic rod 206 is an asymmetric water drop arc structure, one side is a flat surface 2061, the other side is an arc surface 2062, and the connection between the two is provided with an arc support surface 2063, which is an asymmetric arc, and the center of the arc deviates to the end with the arc and increases the arc; The upper surface of one of the two brackets 201 is provided with the above-mentioned magnetic attraction part, which is the upper magnetic attraction part. The attraction section 2011 of the upper magnetic attraction part is an inclined surface that matches the plane 2061 of the magnetic attraction rod 206, and the holding section 2012 is a horizontal surface that matches the supporting surface 2063. When the upper magnetic attraction part is attracted to the magnetic attraction rod 206, the inclined surface is in contact with the plane 2061 of the magnetic attraction rod 206, and the horizontal surface is in contact with the supporting surface 2063 of the magnetic attraction rod 206, and the two cooperate to hold the magnetic attraction rod 206; when the electromagnet inside the magnetic attraction rod 206 changes its polarity and repels the magnet inside the inclined surface, the magnetic attraction rod 206 is pushed away and rotates in a clockwise direction to disengage from the upper magnetic attraction part of the bracket 201, and a limiting portion for limiting the rotation range of the magnetic attraction rod 206 is provided on the transmission rod 203; The magnetic attraction part is provided on the lower surface of another bracket 201 as a lower magnetic attraction part, and the lower magnetic attraction part is an arc-shaped groove, and its suction section 2011 is a first arc-shaped groove wall matched with the arc surface 2062, and the holding section 2012 is a second arc-shaped groove wall matched with the supporting surface 2063; when the transmission rod 203 runs to the position of the other bracket 201, the magnetic attraction rod 206 contacts the bracket 201, and the bracket 201 pushes the magnetic attraction rod 206 to rotate counterclockwise, and as the transmission rod 203 continues to run, the magnetic attraction rod 206 is stuck in the arc-shaped groove. The arc surface 2062 of the magnetic rod 206 is attracted to the first arc groove wall of the lower magnetic part, and the supporting surface 2063 of the magnetic rod 206 is fitted with the second arc groove surface so that the magnetic rod 206 is stuck in the arc groove. At this time, the device is in standby mode, and the transmission rod 203 can be temporarily docked on the bracket 201. When the transmission rod 203 needs to return to the steel cable 202, the electromagnet inside the magnetic rod 206 stops supplying power. At this time, the magnetic rod 206 naturally falls due to gravity and brings the transmission rod 203 back to the steel cable 202.

[0024] like Figure 4 As shown, the transmission rod 203 is equipped with a driving motor 213, a driving pulley 207 connected to the output end of the driving motor 213, a driven pulley 208, and a belt 209 wound around the driving pulley 207 and the driven pulley 208, the clamping wheel 205 is connected to the belt 209, and a slider 212 is installed on the clamping wheel 205, and a slide rail 214 matched with the slider 212 is provided on the transmission rod 203, and the driving pulley 207 and the driven pulley 208 are distributed up and down; start the driving pulley 207, the driving pulley 207 drives the belt 209 to rotate, the belt 209 drives the clamping wheel 205 to move up, the clamping wheel 205 and the transmission wheel 204 clamp the steel cable 202, and during the process, the slider 212 cooperates with the slide rail 214 to guide the lifting and lowering of the clamping wheel 205.

[0025] The bracket 201 includes two cantilevers in an "L"-shaped structure, one of which is an upper cantilever 2013, whose long arm is connected to the lifting mechanism 1, and whose short arm cooperates with the magnetic rod 206; the other cantilever is a lower cantilever 2014, whose short arm is connected to the long arm of the upper cantilever 2013, and the long arm is connected to the steel cable 202.

[0026] like Figure 3 As shown, the lower cantilever 2014 is equipped with a telescopic motor 211 for controlling the telescopic movement of the steel cable 202 and a stress detector 210 for detecting the stress of the steel cable 202. The stress detector 210 transmits a signal to the telescopic motor 211 through a controller. After receiving the signal, the telescopic motor 211 controls whether the steel cable 202 is curled or relaxed to control the stress of the entire steel cable 202 to adapt to the working mode under different working environments. When the steel cable 202 is adjusted, the magnetic rod 206 pops open under the action of the repulsive electromagnetic force, causing the transmission rod 203 to fall onto the steel cable 202.

[0027] Working principle: S1: Start the hydraulic rod 101, which drives the transport mechanism 2 to move up and down so that the transport mechanism 2 is at a working height; S2: The stress detector 210 detects the stress of the steel cable 202 and adjusts the tension of the steel cable 202 to the required tension; S3: The electromagnet in the magnetic rod 206 changes polarity, and repels the magnet in the bracket 201. The magnetic rod 206 is pushed away and rotates away from the bracket 201. At the same time, the transmission rod 203 loses its support and is mounted on the steel cable 202. Figure 6-Figure 8 As shown; S4: The clamping wheel 205 moves upward to clamp the steel cable 202 between the transmission wheel 204 and the clamping wheel 205; S5: The transmission wheel 204 starts to rotate, driving the transmission rod 203 and the object 3 thereon to move along the steel cable 202. Fig. 9 As shown; S6: When the object 3 is transported to the top of the designated location, the conveying rod 203 stops moving, and the hydraulic rod 101 drives the transport mechanism 2 to move downward so that the object 3 falls accurately to the working location; S7: The conveying rod 203 continues to move forward. When the conveying rod 203 moves to the end of the steel cable 202 (i.e., the right bracket), the bracket 201 pushes the magnetic rod 206 to rotate and as the conveying rod 203 continues to move, the magnetic rod 206 is stuck in the arc groove of the bracket 201. At the same time, the magnetic rod 206 and the arc groove of the bracket 201 are attracted to each other. At this time, the device is in a standby state waiting for the next task of transporting the object 3. Figure 10-12 As shown; if the device enters the shutdown state, the transmission rod 203 moves back to the position of the left bracket, and the magnetic rod 206 is attracted to the magnetic portion of the left bracket.

[0032] Working principle: S1: Start the hydraulic rod 101, which drives the transport mechanism 2 to make a rough adjustment so that the transport mechanism 2 is roughly at the working height; S2: Start the lifting motor 105, and drive the transport mechanism 2 to accurately adjust the up and down distance through the cooperation of the worm gear 107, the worm 106 and the lead screw 108; S3: The stress detector 210 detects the stress of the steel cable 202 and adjusts the tension of the steel cable 202 to the required tension; S4: The first driving wheel 109 below the lifting rod 103 rotates to drive the circular track 104 to rotate, thereby driving the carrying mechanism 2 to rotate synchronously; S5: The second driving wheel 110 on the top of the bracket 201 rotates to drive the carrier mechanism 2 to rotate, and the two brackets 201 always maintain 180 degrees relative to each other, and the circular track 104 does not move; S6: The electromagnet in the magnetic rod 206 changes its polarity, and repels the magnet inside the left bracket.
