The present embodiment places an article to be transported on the first stage 1, the first stage 1 moves on the first rail 31 in the first direction, and then the first stage 1 and the article are transferred onto the second stage 2, and then the first stage 1 and the article are transported to the other direction by the second stage 2. Therefore, when the assembly line is replaced to transport articles, the articles are transported and transferred from one assembly line to another assembly line without using machines or manpower, the assembly line transportation efficiency is improved, and the production cost is reduced.

In this embodiment, the first object stage 1 and the second object stage 2 may be a transportation cart, and a driving device, such as a motor, is installed in the transportation cart, and the transportation cart is driven by the motor to move on the transportation rail 3.

In one embodiment, the first rail 31 and the second rail 32 are perpendicular to each other, the first stage 1 moves vertically on the first rail 31, and the second stage 2 moves laterally on the second rail 32.

In the prior art, a bend is generally used in a transverse track and a vertical track to connect the two tracks, and when a transport trolley moves on the bend, articles carried by the transport trolley fall off due to a larger centrifugal force. More seriously, the transport trolley can turn over in the curve, which causes bad production accidents and damages to the transport trolley and the goods. In this embodiment, the second object stage 2 can smoothly transition the first object stage 1 from the first track 31 to the second track 32, and the problem that the first object stage 1 turns over or the article falls off does not occur.

The slope length and the inclination angle of the slope structure 311 may be determined according to the height of the second stage 2. For example, assuming that the height of the second stage 2 is H, the slope length of the slope structure 311 is L, and the inclination angle is α, sin α is H/L according to the sine formula. The height H of the second stage 2 is a known fixed value, in this embodiment H may be 10cm, the inclination angle α is generally not greater than 30 °, in this embodiment 20 ° is selected, and the length of the slope is calculated to be about 29 cm.

The brushless DC motor consists of permanent magnet rotor, multi-pole winding stator, position sensor, etc. The position sensor commutates the current of the stator winding along a certain sequence according to the change of the rotor position (namely, the position of the rotor magnetic pole relative to the stator winding is detected, a position sensing signal is generated at the determined position, the position sensing signal is processed by the signal conversion circuit to control the power switch circuit, and the winding current is switched according to a certain logic relation). The operating voltage for the stator windings is provided by an electronic switching circuit controlled by the position sensor output.

The position sensor is of three types, namely a magnetic-sensing type, a photoelectric type and an electromagnetic type. A brushless DC motor using a magnetic position sensor, in which a magnetic sensor device (e.g., a Hall element, a magnetodiode, a magnetoresistor, or an ASIC) is mounted on a stator assembly to detect a change in a magnetic field generated when a permanent magnet and a rotor rotate.

A brushless DC motor using photoelectric position sensor has a photoelectric sensor on stator, a light shielding plate on rotor, and light source (LED or small bulb). When the rotor rotates, the photosensitive element on the stator intermittently generates pulse signals according to a certain frequency due to the action of the light shielding plate.

A brushless dc motor using an electromagnetic position sensor is a brushless dc motor in which an electromagnetic sensor element (e.g., a coupling transformer, a proximity switch, an LC resonant circuit, etc.) is mounted on a stator assembly, and when the position of a permanent magnet rotor changes, the electromagnetic effect causes the electromagnetic sensor to generate a high-frequency modulation signal (whose amplitude changes with the rotor position).

In one embodiment, the motors of the first stage 1 and the second stage 2 may be three-phase asynchronous motors (Triple-phase asynchronous motors), which are motors powered by 380V three-phase alternating currents (120 degrees out of phase), and since the rotating magnetic fields of the rotors and the stators of the three-phase asynchronous motors rotate in the same direction and at different rotating speeds, there is a slip ratio, so the motors are called three-phase asynchronous motors. The rotating speed of the rotor of the three-phase asynchronous motor is lower than that of a rotating magnetic field, and the rotor winding generates electromotive force and current due to relative motion between the rotor winding and the magnetic field and interacts with the magnetic field to generate electromagnetic torque so as to realize energy conversion. Compared with single-phase asynchronous motor, the three-phase asynchronous motor has good running performance and can save various materials.

In this embodiment, the motor has a single-layer winding structure. The single-layer winding is the winding with only one effective coil side embedded in each stator slot, so that the total number of the coils is only half of the total slot number of the motor. The single-layer winding has the advantages that the process is simple and has fewer winding wire turns; the utilization rate of the groove is improved without interlayer insulation; the single-layer structure does not have interphase breakdown faults and the like.

Can be suitable for various workshop operation environments.

In one embodiment, the first stage 1 and the second stage 2 can be made of aluminum alloy, which has the characteristics of low density, good mechanical properties, good processability, no toxicity, easy recycling, good electrical conductivity, heat conductivity, and corrosion resistance. The aluminum alloy material can make first objective table 1 and 2 quality of second objective table lighter, and intensity is higher, can adapt to harsher workshop environment.
