[0002] At present, in order to ensure the smooth passage of the mover trolley when magnetic drive conveying encounters track intersections, a hybrid mover structure is usually adopted, that is, the mover trolley can run on the magnetic drive straight section and can also be conveyed on the belt line / drum line through fixed friction blocks; when encountering a track intersection, a conveying turntable device is arranged at the center of the track intersection, and the mover trolley is transferred from the magnetic drive line body to the conveying turntable, the turntable rotates to the corresponding track, and then is conveyed to the magnetic drive track by the ordinary conveying line on the turntable.

[0003] In this process, the conveying speed is slow, which greatly affects the conveying efficiency. And when the mover trolley needs to be positioned on the conveying turntable, secondary positioning needs to be achieved through other mechanisms, which makes the whole system more complex and cannot achieve precise positioning. In the application scenario of magnetic drive conveying, how to achieve real-time precise positioning of the mover without using a secondary positioning mechanism during the transfer conveying process is a technical problem to be solved.

Detailed implementation manners

[0017] The technical solutions in the embodiments of the present utility model will be described below with reference to the accompanying drawings in the embodiments of the present utility model:

[0018] As shown in the figure, a turntable system based on magnetic drive transportation includes a magnetic drive track turntable 2, a mover trolley 3, and a plurality of magnetic drive tracks. The plurality of magnetic drive tracks are connected by the rotation of the magnetic drive track turntable 2, and the mover trolley 3 runs on the magnetic drive tracks and the magnetic drive track turntable 2; the mover trolley 3 includes a trolley body 31, a mover magnet 33 is provided at the bottom of the trolley body 31, a plurality of roller bearings 34 are symmetrically arranged on both sides of the mover magnet 33, and the first induction magnet group 32 and the second induction magnet group 35 are arranged opposite to each other front and back. In this embodiment, taking the number of a plurality of magnetic drive tracks as four as an example, it includes a first magnetic drive track 11, a second magnetic drive track 12, a third magnetic drive track 13, and a fourth magnetic drive track 14. The four magnetic drive tracks are distributed around the same circumference; the magnetic drive track turntable 2 includes a transition magnetic drive track 21 and a rotating turntable 25. The transition magnetic drive track 21 is arranged above the rotating turntable 25 and the length of the transition magnetic drive track 21 is greater than the diameter of the rotating turntable 25. The transition magnetic drive track 21 can make any angle of rotation along with the rotating turntable 25, and the rotation center of the transition magnetic drive track 21 is the center of the circle where the four magnetic drive tracks are located; since both ends of the transition magnetic drive track 21 are outer arcs, one ends of the first magnetic drive track 11, the second magnetic drive track 12, the third magnetic drive track 13, and the fourth magnetic drive track 14 close to the transition magnetic drive track 21 are inner arcs; both the inner arc and the outer arc are centered on the rotation center of the transition magnetic drive track 21 and the radius of the inner arc is greater than the radius of the outer arc, so that the transition magnetic drive track 21 can make any angle of rotation within the circumference surrounded by the plurality of magnetic drive tracks. The self-rotation axis of the magnetic drive track turntable 2 passes through the rotation center of the transition magnetic drive track 21 and is perpendicular to the cross-section of the rotating turntable 25. The magnetic drive track turntable 2 has a first state and a second state. When the magnetic drive track turntable 2 is in the first state, the transition magnetic drive track 21 connects the first magnetic drive track 11 and the third magnetic drive track 13; when the magnetic drive track turntable 2 is in the second state, the transition magnetic drive track 21 connects the second magnetic drive track 12 and the fourth magnetic drive track 14.

[0019] The first magnetic drive track 11, the second magnetic drive track 12, the third magnetic drive track 13, and the fourth magnetic drive track 14 all include a track body 111. On both sides of the track body 111, there are first guide rails 112. On the outer side of one of the first guide rails 112, there is a first Hall displacement sensor 114. In the middle of the track body 111, there is a first motor coil 113; the first Hall displacement sensor 114 senses the position of the first induction magnet group 32 to obtain the accurate position of the mover trolley on the magnetic drive track. When the mover trolley 3 is on the first magnetic drive track 11, the mover magnet 33 corresponds to the first motor coil 113 to provide magnetic driving force for the mover trolley 3, and the first induction magnet group 32 corresponds to the first Hall displacement sensor 114 to provide the accurate position of the mover trolley 3. The six roller bearings 34 and the two first guide rails 112 form a moving pair. When the first motor coil 113 is energized, it drives the mover magnet 33 to move. The first Hall displacement sensor 114 senses the position of the first induction magnet group 32 in real time and realizes the high-precision control of the motor. The movement of the mover trolley 3 on the second magnetic drive track 12, the third magnetic drive track 13, and the fourth magnetic drive track 14 is the same.

[0020] The magnetic drive track turntable 2 includes a transition magnetic drive track 21 and a rotating turntable 25. On both sides of the transition magnetic drive track 21, there are second guide rails 23. On the outer sides of the two second guide rails 23, there are a second Hall displacement sensor 22 and a third Hall displacement sensor 26 respectively. In the middle of the two second guide rails 23, there is a second motor coil 24. Since the two ends of the transition magnetic drive track 21 are outer arcs, the center of the outer arc is the rotation center of the transition magnetic drive track 21, and the second Hall displacement sensor 22 and the third Hall displacement sensor 26 are mirror-symmetrically arranged. When the mover trolley 3 is on the magnetic drive track turntable 2, the mover magnet 33 corresponds to the second motor coil 24, the first induction magnet group 32 corresponds to the second Hall displacement sensor 22, the second induction magnet group 35 corresponds to the third Hall displacement sensor 26, and the six roller bearings 34 and the two second guide rails 23 form a moving pair. When the second motor coil 24 is energized, it drives the mover magnet 33 to move. The mover trolley 3 is driven by magnetic force before, during, and after the transfer.

[0021] Both ends of the transition magnetic drive track 21 are in the shape of outer arcs. The inner arcs of several magnetic drive tracks and the outer arcs at both ends of the transition magnetic drive track 21 are concentric and have the same track height, with a slight gap reserved to ensure the smooth rotation of the transition magnetic drive track 21. When the mover trolley 3 transitions between the transition magnetic drive track 21 and the first magnetic drive track 11, the motor coil is energized to provide a moving thrust. Since both ends of the transition magnetic drive track 21 are in the shape of outer arcs and both ends of the second Hall displacement sensor 22 and the third Hall displacement sensor 26 are linear, there is a certain distance between the second Hall displacement sensor 22 and the third Hall displacement sensor 26 and both ends of the transition magnetic drive track 21. And because the end of the first magnetic drive track 11 is an inner arc, there is also a certain distance between the first Hall displacement sensor 114 and the end of the first magnetic drive track 11. Therefore, the Hall displacement sensors at the transition section between the inner arc and the outer arc are arranged in a disconnected manner, and there is a situation where the position of the mover trolley 3 cannot be recognized in this transition section. For this reason, a first induction magnet group 32 and a second induction magnet group 35 arranged front and back relative to each other are fixed on both sides of the mover trolley 3. When the mover trolley 3 passes through the transition section, the first induction magnet group 32 passes through the transition section first. At this time, the first induction magnet group 32 does not provide a position feedback signal. And the second induction magnet group 35 on the other side is on the complete Hall displacement sensor, and the second induction magnet group 35 performs normal position feedback. After the first induction magnet group 32 passes through the transition section, it starts to work normally and provides a position feedback signal. In this way, the position feedback of the whole line is realized, ensuring the position accuracy.

[0022] In an automated production line body, the utility model can be arranged on the main magnetic drive conveyor line body to realize a 180° or any angle turn of the mover trolley 3, and the requirement of real-time precise positioning of the mover trolley 3 can be met without secondary positioning.

[0023] The above embodiments are only a part of the embodiments of the utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.
