Description

Technical Field

[0001] The invention relates to the technical field of material transfer, and in particular to a precisely positioned coil material docking mechanism. Background Art

[0002] When the existing cantilever shaft AGV docks small rolls of materials, it is generally positioned based on the AGV as a whole. The sensor on the AGV cantilever shaft detects the center difference between the AGV cantilever shaft and the equipment cantilever shaft, and then moves forward slowly and continuously adjusts its posture to eventually achieve a state where the two cantilever shafts are concentric. However, the positioning accuracy of the AGV body is limited, and currently only the docking height can be adjusted, and the horizontal deviation cannot be accurately adjusted. When the AGV cantilever shaft carries materials, there will be deflection, forming an angle between it and the cantilever shaft of the equipment, and in severe cases, it cannot be docked. In addition, due to the limited overall positioning accuracy of the AGV, the vehicle body needs to be slowly adjusted during docking, resulting in a long docking time and low material transfer efficiency.

[0020] Description of the accompanying drawings: 100 connecting frame, 110 shaft body, 111 limiting block, 1111 limiting groove, 120 supporting pulley, 130 bushing, 200 mounting seat, 300 horizontal adjustment assembly, 310 first rotating drive member, 320 first adjusting cam, 321 cam portion, 322 adapter portion, 330 origin sensor, 400 deflection adjustment assembly, 410 second rotating drive member, 420 second adjusting cam, 500 cantilever shaft. DETAILED DESCRIPTION

[0021] The embodiments of the present invention are described in detail below. Figures 1 to 5 The embodiment of the present invention provides a precisely positioned coil docking mechanism, comprising a connecting frame 100, a mounting seat 200, a horizontal adjustment assembly 300, a deflection adjustment assembly 400 and a cantilever shaft 500. The connecting frame 100 is used to install the entire coil docking mechanism on the lifting gantry of the AGV, the cantilever shaft 500 is installed on the mounting seat 200, the mounting seat 200 is slidably and rotatably connected to the connecting frame 100, the horizontal adjustment assembly 300 is used to drive the mounting seat 200 and the cantilever shaft 500 to move horizontally relative to the connecting frame 100, and the deflection adjustment assembly 400 is used to drive the mounting seat 200 and the cantilever shaft 500 to deflect relative to the connecting frame 100.

[0022] The coil docking mechanism is provided with a horizontal adjustment component 300 and a deflection adjustment component 400, which can adjust the horizontal deviation and deflection deviation of the cantilever shaft 500 during docking, so that the cantilever shaft 500 of the detection AGV can be concentric with the docking shaft of the docking device, and achieve precise positioning and docking. During docking, the detection AGV can be quickly moved to a specific position for preliminary positioning, and then there is no need to use the AGV overall positioning. Instead, the horizontal deviation and deflection deviation of the cantilever shaft 500 are adjusted through the coil docking mechanism to smoothly perform the positioning and docking of the cantilever shaft 500 and the docking shaft, which can reduce the positioning accuracy requirements of the AGV body, greatly shorten the time required for positioning and docking, and improve production efficiency.

[0023] Further, refer to Figure 2 and Figure 3The connecting frame 100 is provided with an axis body 110, and the mounting seat 200 is slidably and rotatably connected to the axis body 110. The horizontal adjustment assembly 300 is used to drive the mounting seat 200 to slide along the axis body 110. When the mounting seat 200 slides along the axis body 110, the cantilever shaft 500 on the mounting seat 200 can be driven to slide relative to the connecting frame 100, thereby adjusting the horizontal deviation of the cantilever shaft 500. The deflection adjustment assembly 400 is used to drive the mounting seat 200 to rotate around the axis body 110. When the mounting seat 200 rotates around the axis body 110, the cantilever shaft 500 on the mounting seat 200 can be driven to deflect around the axis body 110, thereby adjusting the deflection deviation of the cantilever shaft 500. Further, the mounting seat 200 is slidably and rotatably connected to the axis body 110 through the bushing 130. The bushing 130 can serve as a support and guide when the mounting seat 200 moves horizontally, so that the horizontal movement of the mounting seat 200 is smoother. Furthermore, two bushings 130 are provided on both sides of the mounting base 200 , and an origin sensor 330 is provided on the mounting base 200 , which can be used as a reference point for horizontal adjustment.

[0024] Further, the horizontal adjustment assembly 300 includes a first rotary drive member 310 and a first adjustment cam 320. The first rotary drive member 310 is mounted on the mounting seat 200. The first adjustment cam 320 is fixedly mounted on the output end of the first rotary drive member 310. The rotation axis of the first adjustment cam 320 is in the vertical direction, and the first adjustment cam 320 is rotatably connected to the shaft body 110 or the connecting frame 100. The first rotary drive member 310 is fixedly mounted on the mounting seat 200. When the first rotary drive member 310 drives the first adjustment cam 320 to rotate, the distance between the first adjustment cam 320 and the mounting seat 200 will change. The first adjustment cam 320 is rotatably connected to the shaft body 110 or the connecting frame 100, so it will be limited by the shaft body 110 or the connecting frame 100 in the horizontal direction, thereby reacting to the mounting seat 200, and finally causing the mounting seat 200 to slide relative to the connecting frame 100 along the shaft body 110, thereby adjusting the deviation of the cantilever shaft 500. Furthermore, the first rotary driving member 310 may be a rotary motor or the like.

[0025] Further, refer to Figure 2 A limiting block 111 is fixedly mounted on the shaft body 110, and the limiting block 111 is provided with a limiting groove 1111, and the lower part of the limiting groove 1111 has an opening. Figure 3The first adjusting cam 320 includes a cam portion 321 and an adapter portion 322. The cam portion 321 is fixedly mounted on the output shaft of the first rotating driving member 310, so that the rotation axis of the cam portion 321 coincides with the output shaft of the first rotating driving member 310. The adapter portion 322 is rotatably connected to the cam portion 321, and the rotation axis of the adapter portion 322 deviates from the rotation axis of the cam portion 321. The adapter portion 322 extends into the limiting groove 1111 from the opening at the lower part of the limiting groove 1111, thereby being restricted by the limiting block 111. Therefore, when the first rotating driving member 310 drives the first adjusting cam 320 to rotate, the eccentric installation of the adapter portion 322 causes the horizontal distance between the adapter portion 322 and the mounting seat 200 to change, and the adapter portion 322 is restricted by the limiting block 111, so it will react to the mounting seat 200, so that the mounting seat 200 slides horizontally along the shaft body 110. The present coil docking mechanism uses the rotation of a cam to convert into horizontal sliding of the mounting seat 200, rather than using a screw slide rail structure commonly used in traditional deviation correction. On the one hand, the layout of the internal components of the mounting seat 200 can be more reasonable, saving internal space and making the structure of the coil docking mechanism more compact. On the other hand, the rotation of a cam is used to convert into horizontal sliding of the mounting seat 200, which is more conducive to adjusting the horizontal sliding of the mounting seat 200 with a small stroke, thereby facilitating more precise adjustment of the horizontal deviation of the cantilever shaft 500.

[0026] Further, refer to Figure 4 and Figure 5The deflection adjustment assembly 400 includes a second rotary drive member 410 and a second adjustment cam 420. The second rotary drive member 410 is mounted on the mounting seat 200. The second adjustment cam 420 is fixedly mounted on the output end of the second rotary drive member 410. The rotation axis of the second adjustment cam 420 is in the horizontal direction, and the second adjustment cam 420 abuts against the connecting frame 100. The second rotary drive member 410 can drive the second adjustment cam 420 to rotate, so as to drive the mounting seat 200 to swing around the shaft body 110. When the second rotary drive member 410 drives the second adjustment cam 420 to rotate, the distance between the second adjustment cam 420 and the connecting frame 100 will change. Relying on the abutment force between the second adjustment cam 420 and the connecting frame 100, it acts on the mounting seat 200, so that the mounting seat 200 swings around the shaft body 110, and finally adjusts the deflection deviation of the cantilever. Furthermore, a support pulley 120 is rotatably mounted on the connecting frame 100, and the second adjusting cam 420 abuts against the support pulley 120. The support pulley 120 serves as a support for the second adjusting cam 420, which can reduce the abutment area between the second adjusting cam 420 and the support pulley 120, reduce friction, and make the second adjusting cam 420 rotate more smoothly, thereby better driving the mounting seat 200 to swing around the shaft body 110. Furthermore, the axis of the second adjusting cam 420 is perpendicular to the axis of the support pulley 120, that is, the axis of the support pulley 120 is in the vertical direction. When the horizontal adjustment assembly 300 drives the mounting seat 200 to move horizontally relative to the connecting frame 100, the second adjusting cam 420 and the support pulley 120 will also move relative to each other in the horizontal direction. At this time, the support pulley 120 can rotate around its own axis, thereby reducing friction during horizontal movement and reducing wear.

[0027] Furthermore, two second adjustment cams 420 are provided in the direction of horizontal movement of the mounting seat 200, and the two second adjustment cams 420 are arranged on both sides of the mounting seat 200, and two supporting pulleys 120 are also provided accordingly, so that when the second adjustment cams 420 drive the mounting seat 200 to deflect, the mounting seat 200 is subjected to a more balanced force. Furthermore, a rotating shaft can be provided on the mounting seat 200, and the two second adjustment cams 420 are respectively fixedly installed at both ends of the rotating shaft, and a driven gear is fixedly installed on the rotating shaft. The second rotating driving member 410 can adopt a structure such as a rotating motor, and a driving gear is installed at the output end of the rotating motor, and the driving gear is meshed and connected with the driven gear. When the rotating motor is started, the driving gear will transmit power to the driven gear, so that the driven gear drives the rotating shaft to rotate, and then drives the second adjustment cams 420 at both ends of the rotating shaft to rotate.

[0028] The present coil docking mechanism has an axle 110 installed on the connecting frame 100. The axle 110 is both a supporting and guiding structure for the horizontal movement of the entire mounting seat 200 and a central axis for deflection adjustment. At the same time, two adjustment cams are arranged in the mounting seat 200. The rotation and conversion of the adjustment cams are utilized to realize the horizontal adjustment and deflection adjustment of the mounting seat 200. The two adjustment structures are cleverly combined, which saves the internal space of the mounting seat 200 and makes the structure of the mounting seat 200 more compact.
