DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model:

[0017] As shown in the figure, a low-cost magnetic drive conveying structure includes a base 12. A linear guide rail 11 is arranged above the base 12. The mover mechanism 2 is L-shaped. One end of its side is provided with a mounting seat 21. A slider 24 is fixed to the bottom of the mounting seat 21. The mover mechanism 2 drives and slides along the linear guide rail 11 through the slider 24, and the slider 24 slides along the linear guide rail 11. The slider 24 is fixed to the bottom of the mounting seat 21. A plurality of power magnet groups 22 and a plurality of induction magnet groups 23 are arranged at intervals at the bottom of the other side of the mover mechanism 2. A plurality of brackets 13 are provided on one side of the base 12 opposite to the linear guide rail 11. A displacement sensor 15 is fixed on the bracket 13. The displacement sensor 15 and the bracket 13 are provided with a fixing plate 14 extending into the interior of the mover mechanism 2. One end of the fixing plate 14 close to the mounting seat 21 is fixed with a magnetic drive stator 16. The magnetic drive stator 16 is located below the power magnet group 22. When the magnetic drive stator 16 is energized, it can drive the upper power magnet group 22 through the magnet, so as to drive the mover mechanism 2 to move along the linear guide rail 11; the displacement sensor 15 is located below the induction magnet group 23.

[0018] When the length of the mover mechanism 2 allows it to be relatively long, a plurality of power magnet groups 22 can be arranged on the mover mechanism 2. The length of the magnetic drive stator 16 is 300 mm. One of the embodiments is as Figure 3 shown. The plurality of power magnet groups 22 include a magnet group one 221, a magnet group two 222, a magnet group three 223, and a magnet group four 224, which are arranged at intervals of 300 mm in sequence. The total length of the linear guide rail 11 is 2400 mm. Then, two magnetic drive stators 16 are required, namely a magnetic drive stator one 161 and a magnetic drive stator two 162. The center distance between the magnetic drive stator one 161 and the magnetic drive stator two 162 is 1200 mm. As Figure 3The moving element mechanism 2 shown has a first state, a second state, a third state, and a fourth state during the forward movement. The first state is when the fourth magnet group 224 is directly above the first magnetic drive stator 161, and the first magnetic drive stator 161 is energized to drive the fourth magnet group 224 to move to the right; in the second state, the fourth magnet group 224 is about to leave the range of the first magnetic drive stator 161, and the first magnet group 221 is about to enter the range of the second magnetic drive stator 162. A part of the fourth magnet group 224 is in contact with the first magnetic drive stator 161, and a part of the first magnet group 221 is in contact with the second magnetic drive stator 162, and a constant magnetic driving force can still be provided for the moving element mechanism 2; in the third state, the first magnet group 221 is about to leave the range of the second magnetic drive stator 162, and the second magnet group 222 is about to enter the range of the second magnetic drive stator 162, and the magnetic driving force received by the moving element mechanism 2 comes from the second magnet group 222 and the first magnet group 221; in the fourth state, the third magnet group 223 is about to leave the range of the second magnetic drive stator 162, and the fourth magnet group 224 is about to enter the range of the second magnetic drive stator 162; from this, it can be seen that at any moment, a magnet group with the same area corresponds to the magnetic drive stator 16, that is, the thrust generated by the motor drive is constant. At the same time, the length of the displacement sensor 15 can be the same as that of the magnetic drive stator 16, or an integer multiple of the length of the magnetic drive stator 16. For example, Figure 5 As shown in the illustration given, if the length of the displacement sensor 15 is twice that of the magnetic drive stator 16, and the length of the magnetic drive stator 16 is 300 mm, then the length of the displacement sensor 15 is 600 mm. Then, the spacing of the induction magnet groups 23 provided on the moving element mechanism 2 also needs to be set to 600 mm. The length of the moving element mechanism 2 is 1200 mm, so two induction magnet groups 23 need to be installed. The two induction magnet groups 23 are the first induction magnet group 231 and the second induction magnet group 232 respectively. The center spacing between the first induction magnet group 231 and the second induction magnet group 232 is 600 mm. When the full length of the linear guide 11 is 2400 mm, two displacement sensors 15 with a length of 600 mm need to be installed. The two displacement sensors 15 are the first displacement sensor 151 and the second displacement sensor 152 respectively. The center distance between the first displacement sensor 151 and the second displacement sensor 152 is 1200 mm.

[0019] The setting methods of the displacement sensor 15 and the magnetic drive stator 16 include, but are not limited to, the above intervals, but all follow the following method: The length of each section of the magnetic drive stator 16 is denoted as N. If the contact of a group of dynamic magnetic steel groups 22 with the magnetic drive stator 16 can meet the power required for the operation of the mover mechanism 2, then the center distance between two adjacent dynamic magnetic steel groups 22 is also N. The length of the mover mechanism 2 is L, and the length of the dynamic magnetic steel group 22 is P. N, L, P, and S satisfy P < N and L ≥ P + N*(S - 1) (S is a positive integer). Then the number of required dynamic magnetic steel groups 22, S ≤ [(L - P) / N + 1], and when S ≥ 2, the magnetic drive stators 16 can be arranged at intervals. The center distance between two adjacent magnetic drive stators 16 is S*N, and a magnetic drive transmission line with a length of L only requires one group of magnetic drive stators 16. This way of structural optimization not only reduces the cost of the magnetic drive stator 16 but also correspondingly reduces the cost of the driver controller of the magnetic drive stator. The length of the displacement sensor 15 is M, then the distance between multiple induction magnetic steel groups 23 arranged on the mover mechanism 2 is M, and the length of the induction magnetic steel group 23 is Q (Q is much smaller than M). When L ≥ Q + M*(S1 - 1) (S1 is a positive integer), then S1 ≤ [(L - Q) / M + 1]. It can be seen that when S1 ≥ 2, the displacement sensors 15 can be arranged at intervals, and the center distance between adjacent displacement sensors 15 is S1*M. The relationship between M and N can also be M = aN, where a is a positive integer. For example, the length of a magnetic drive stator 16 is 300 mm, then the center distance between adjacent dynamic magnetic steel groups 22 among multiple dynamic magnetic steel groups 22 arranged on the mover mechanism 2 is also 300 mm. The length of the mover mechanism 2 is 1200 mm, then four groups of dynamic magnetic steel groups 22 are arranged on the mover mechanism 2, and the distance between adjacent magnetic steel groups is 300 mm. A 300-mm-long magnetic drive stator 16 is only required for a 1200-mm-long track, and the other 900 mm does not require a magnetic drive stator 16, saving 75% of the layout of the magnetic drive stator 16. Similarly, the above method can also be used for the layout of the displacement sensor 15. The length of the displacement sensor 15 is an integer multiple of 300 mm. For example, if the length of the displacement sensor 15 is 600 mm, then the center distance between adjacent induction magnetic steel groups 23 arranged on the mover mechanism 2 is also 600 mm. Two induction magnetic steel groups 23 are arranged on the 1200-mm mover mechanism 2, and the center distance between adjacent displacement sensors 15 is 1200 mm, saving 50% compared with laying the displacement sensor along the full length. At any time, there is an induction magnetic steel group 23 within the range of the displacement sensor 15. If the length of the displacement sensor 15 is 300 mm, then the center distance between adjacent induction magnetic steel groups 23 arranged on the mover mechanism 2 is also 300 mm. Four induction magnetic steel groups 23 are arranged on the 1200-mm mover mechanism 2, and the center distance between adjacent displacement sensors 15 is 1200 mm, saving 75% compared with laying the displacement sensor along the full length. Similarly, at any time, there is an induction magnetic steel group 23 within the range of the displacement sensor 15.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
