[0001] The utility model relates to the technical field of magnetic levitation conveying devices, and specifically relates to a magnetic levitation conveying device. Background Technique

[0002] Magnetic levitation technology refers to a technology that uses magnetic force to overcome gravity to suspend an object. Suspension technologies mainly include magnetic levitation, optical levitation, acoustic levitation, air current suspension, electric suspension, particle beam suspension, etc. Among them, magnetic levitation technology is relatively mature, and there are many forms of realizing magnetic levitation technology. It can be mainly divided into passive suspension with system self-stabilization and active suspension without system self-stabilization, etc.;

[0003] Magnetic levitation is mainly applied to maglev high-speed trains. A maglev train is a new type of transportation composed of a contactless magnetic force support, magnetic force guidance, and linear drive system. There are mainly superconducting electric maglev trains, conventional electromagnetic suction type high-speed maglev trains, and conventional electromagnetic suction type medium and low-speed maglev trains. Magnetic levitation can also be applied to the transportation during the production and assembly of mobile phone parts, shortening the transmission time of mobile phone parts and improving the assembly or production efficiency of mobile phones.

[0004] However, when mobile phone parts are transported by magnetic levitation, due to the limitation of the production site, there are curved corners on the conveying line, resulting in the inability of the parts to turn autonomously when passing through the corners and the need for intervention, so there is a risk of retention when the parts pass through the corners; Therefore, it does not meet the existing requirements, and for this reason, we propose a magnetic levitation conveying device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a magnetic levitation conveying device to solve the problems mentioned in the above background technique, that is, when mobile phone parts are transported by magnetic levitation, due to the limitation of the production site, there are curved corners on the conveying line, resulting in the inability of the parts to turn autonomously when passing through the corners and the need for intervention, so there is a risk of retention when the parts pass through the corners.

The tops of the plurality of support columns are fixed with a magnetic levitation conveying line. Two conveying line side guards are fixed on the upper surface of the magnetic levitation conveying line.

An elastic connecting piece is fixed between one of the corner guiding and protecting parts and one of the conveying line side guards. A limiting plate is fixed inside this conveying line side guard. One end of the corner guiding and protecting part close to this limiting plate is lapped with a guiding plate. The guiding plate is in an inclined state and one end thereof is attached to the inner surface of the conveying line side guard where the limiting plate is installed.

[0007] Preferably, the elastic connecting piece is an elastic metal piece and is bent in a V shape in the middle. Both ends of the elastic connecting piece are bent in a 90-degree arc and are respectively fixed to one side guardrail of the conveying line and the corner guiding and protecting piece.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] As Figures 1 to 4 shown, a maglev conveying device, the top ends of a plurality of support columns 1 are fixed with a maglev conveyor line 2, two conveyor line side guardrails 3 are fixed on the upper surface of the maglev conveyor line 2, and a plurality of corner guiding and protecting parts 4 are arranged above the corners of the maglev conveyor line 2. The plurality of corner guiding and protecting parts 4 are evenly distributed around the center of the corner of the maglev conveyor line 2. An elastic connecting piece 6 is fixed between one of the corner guiding and protecting parts 4 and one of the conveyor line side guardrails 3. A limiting plate 7 is fixed on the inner side of this conveyor line side guardrail 3. One end of the corner guiding and protecting part 4 close to the limiting plate 7 is lapped with a guiding plate 5. The guiding plate 5 is in an inclined state and one end thereof is attached to the inner surface of the conveyor line side guardrail 3 where the limiting plate 7 is installed. The conveyor line side guardrail 3 and the corner guiding and protecting part 4 are used to guide the turning of the parts being transported on the surface of the maglev conveyor line 2, reducing the impact between the parts and the corner guiding and protecting part 4 while enabling the parts to turn smoothly, ensuring that the parts will not stay at the corner of the maglev conveyor line 2.

[0021] The elastic connecting piece 6 is an elastic metal piece and is bent in a V shape in the middle. The two ends of the elastic connecting piece 6 are bent in a 90-degree arc and are respectively fixed to one of the conveyor line side guardrails 3 and the corner guiding and protecting part 4. The elastic connecting piece 6 with elasticity connects the corner guiding and protecting part 4, enabling the corner guiding and protecting part 4 to move a certain distance in the direction of being impacted and elastically approach the conveyor line side guardrail 3 after being hit, reducing the impact force of the parts on the corner guiding and protecting part 4, avoiding damage to the parts, and the elastic reset of the corner guiding and protecting part 4 is driven when the parts leave.

[0022] The corner guiding and protecting part 4 includes a connecting piece 41. The connecting piece 41 is fixed to one end of the elastic connecting piece 6. One side of the connecting piece 41 is fixed with an arc piece 42. The other side of the arc piece 42 is fixed with a guiding piece 43. The other side of the guiding piece 43 is fixed with a protecting bending piece 44. The guiding piece 43 is inclined and has a smooth surface. The protecting bending piece 44 is arc-shaped and one side edge thereof fits the rear surface of the guiding piece 43. The arc piece 42 is arc-shaped so that the guiding piece 43 can bend towards the side guardrail 3 of the conveying line after being stressed. The existence of the protecting bending piece 44 makes the side edge of the guiding piece 43 a smooth arc surface, enabling the parts to smoothly move from the surface of one guiding piece 43 to the surface of another guiding piece 43. During this process, the guiding piece 43 will not damage the parts.

[0023] An inserting plate 8 is fixed to the inner side of the end of the guiding plate 5 that fits the side guardrail 3 of the conveying line. The end of the inserting plate 8 away from the guiding plate 5 is inserted between the limiting plate 7 and the side guardrail 3 of the conveying line. A groove is provided inside the limiting plate 7. An arc-shaped depression 9 is provided on the inner side of the end of the inserting plate 8 connected to the limiting plate 7. The arc-shaped depression 9 makes the outer surface of the end of the limiting plate 7 form an arc-shaped protrusion, and the arc-shaped protrusion is clamped in the groove inside the limiting plate 7. The limiting plate 7 and the inserting plate 8 are used to limit the position of the guiding plate 5, ensuring that the guiding plate 5 shields the end of the corner guiding and protecting part 4, preventing the parts from directly entering between the corner guiding and protecting part 4 and the side guardrail 3 of the conveying line and staying on the surface of the maglev conveying line 2.

[0024] Working principle: First, connect the power supply of the maglev conveying device and start it. After the power supply is connected, the parts are transported from one end of the maglev conveying line 2 to the other end. When the parts reach the corner of the maglev conveying line 2, the parts first come into contact with the surface of the guiding plate 5 or the frontmost corner guiding and protecting part 4. After the parts come into contact with the corner guiding and protecting part 4, a force pointing towards the side guardrail 3 of the conveying line is generated on the corner guiding and protecting part 4. At this time, the guiding piece 43 drives the protecting bending piece 44 to bend in an arc around the center of the arc piece 42 towards the side guardrail 3 of the conveying line. During this process, the parts interact with the surface of the guiding piece 43 and deflect in angle. The parts are transferred from the surface of this corner guiding and protecting part 4 to the surface of the next corner guiding and protecting part 4. After the parts come into contact with the next corner guiding and protecting part 4, the parts also exert a thrust on the guiding piece 43, causing the guiding piece 43 to drive the protecting bending piece 44 to bend in an arc around the center of the arc piece 42 towards the side guardrail 3 of the conveying line. During this process, the parts deflect by an angle again until the parts come into contact with the last corner guiding and protecting part 4. At this time, the corner guiding and protecting part 4 completes a 90-degree deflection, ensuring that the parts conveyed on the surface of the maglev conveying line 2 smoothly complete the forward direction conversion at the corner of the maglev conveying line 2 and will not stay at the corner of the maglev conveying line 2, improving the conveying efficiency of the parts.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
