Description

Technical Field

[0001] The utility model relates to the technical field of mobile phones, and particularly relates to a linear magnetic levitation conveyor belt structure. Background Technique

[0002] The working principle of the linear magnetic levitation conveyor belt mainly depends on the magnetic levitation technology and the principle of linear motor. Specifically, it cuts the servo motor perpendicular to the axis and straightens and extends it into a track, and the mover with magnets (i.e., the object to be conveyed) will move horizontally on the track. Through the action of the magnetic field, the conveyed item can be suspended on the conveyor line and maintain the suspended state of the object through the magnetic force balance control technology, realizing non-contact transmission. At the same time, through the motion control algorithm, multiple movers can be independently controlled to achieve synchronous or asynchronous flexible transmission;

[0003] This linear magnetic levitation conveyor belt is mainly used in material handling, assembly, testing and other links, especially in environments that require dust-free, noise-free and high-precision positioning, such as semiconductor manufacturing, pharmaceutical production and mobile phone assembly processes. When this linear magnetic levitation conveyor belt is applied to mobile phone assembly, the semi-finished mobile phones can be moved to the corresponding processing areas one by one.

[0004] However, when using the linear magnetic levitation conveyor belt as a conveying device on the mobile phone production line, since the positions of multiple sliders inside the linear magnetic levitation conveyor belt cannot be exchanged, when one of the sliders gets stuck at a certain position on the equipment, the subsequent moving sliders can only stop behind this slider until this slider moves forward, so that the subsequent blocked sliders can continue to move. This leads to the situation that when moving the semi-finished mobile phone to a processing position with a longer processing time compared to other processes through the slider, the subsequent moving sliders can only stay behind this slider, resulting in the blockage of the production line and affecting the production efficiency of mobile phones. Therefore, it does not meet the existing requirements, and for this reason, we propose a linear magnetic levitation conveyor belt structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a linear magnetic levitation conveyor belt structure to solve the problems raised in the above background technique.

This leads to the situation that when moving the semi-finished mobile phone to a processing position with a longer processing time compared to other processes through the slider, the subsequent moving sliders can only stay behind this slider, resulting in the blockage of the production line and affecting the production efficiency of mobile phones.

[0016] 1. When this device is used in mobile phone production, the robotic arm for long-time process treatment of the mobile phone is installed on one side of the first mobile maglev conveying short rail. Then, the semi-finished mobile phone is placed on the upper end face of the sliding table.

Then, the robotic arm installed on one side of the first mobile maglev conveying short rail can perform long-time process treatment on the semi-finished mobile phone located above the first mobile maglev conveying short rail. And then, the sliding table moving along the first maglev conveying rail will move to another first mobile maglev conveying short rail through the second mobile maglev conveying short rail connected to the first maglev conveying rail at this time. After the process treatment of the semi-finished mobile phone is completed, the first mobile maglev conveying short rail can be pulled back to its original position through the stepping motor.

[0017] 2. When the second movable magnetic levitation conveying short rail is moved to the position where the first movable magnetic levitation conveying short rail was originally located, the positioning motor can move the external thread positioning column upward.

If the second movable magnetic levitation conveying short rail moved here is not completely aligned with the first magnetic levitation conveying rail, the position of the second movable magnetic levitation conveying short rail can be adjusted by the push of the flat cone. Through the above technical solution, the alignment accuracy between the second movable magnetic levitation conveying short rail and the first magnetic levitation conveying rail can be improved.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] The first magnetic levitation conveying rail 2 (model number KNK3005), stepper motor 8 (model number DM542), and thread transmission rod 9 (model number M16) mentioned in the present utility model can be obtained by purchasing from the market or customizing privately.

[0025] Please refer to Figures 1 to 4, an embodiment provided by the present utility model: a linear magnetic levitation conveyor belt structure, including a magnetic levitation conveyor belt base 1. On one side of the upper end surface of the magnetic levitation conveyor belt base 1, a first magnetic levitation conveyor track 2 is fixedly provided. In front of the first magnetic levitation conveyor track 2, there are a plurality of first movable magnetic levitation conveyor short tracks 5. In front of the first first movable magnetic levitation conveyor short track 5 counted from front to back, there is a second magnetic levitation conveyor track 4, and the cross-sectional shapes of the first magnetic levitation conveyor track 2, the second magnetic levitation conveyor track 4, and the first movable magnetic levitation conveyor short track 5 are the same;

[0026] On one side of the first movable magnetic levitation conveyor short track 5, there is a second movable magnetic levitation conveyor short track 7. On both sides of the surface of the second movable magnetic levitation conveyor short track 7 facing the first movable magnetic levitation conveyor short track 5, a connecting block 6 is fixedly provided, and the surface of the connecting block 6 facing the first movable magnetic levitation conveyor short track 5 is fixed to the first movable magnetic levitation conveyor short track 5;

[0027] Below the second movable magnetic levitation conveyor short track 7, there is an L-shaped support base 18 fixed to the magnetic levitation conveyor belt base 1. On one side inside the L-shaped support base 18, a stepping motor 8 is fixedly installed. The output shaft of the stepping motor 8 is connected to a threaded transmission rod 9 through a coupling. The threaded transmission rod 9 horizontally penetrates through the first movable magnetic levitation conveyor short track 5 and the second movable magnetic levitation conveyor short track 7. The threaded transmission rod 9 is threadedly connected to the first movable magnetic levitation conveyor short track 5 and the second movable magnetic levitation conveyor short track 7, and on both sides of the threaded transmission rod 9, there is a guide rod 10 that horizontally penetrates through the first movable magnetic levitation conveyor short track 5 and the second movable magnetic levitation conveyor short track 7.

[0028] The cross-sectional shapes of the first movable maglev conveying short rail 5 and the second movable maglev conveying short rail 7 are the same, and the lengths of the first movable maglev conveying short rail 5 and the second movable maglev conveying short rail 7 are also the same; on one side of the upper end surface of the first maglev conveying rail 2, a sliding table 3 is installed, and the first maglev conveying rail 2 is fixed to the maglev conveyor belt base 1 by bolts; when this device is used in mobile phone production, a robotic arm for long-time processing of mobile phones is installed on one side of the first movable maglev conveying short rail 5, and then the semi-finished mobile phone is placed on the upper end surface of the sliding table 3. After that, when the sliding table 3 moves along the first maglev conveying rail 2 to the upper end surface of the first movable maglev conveying short rail 5, the movement of the sliding table 3 is stopped. Then, the stepping motor 8 will be automatically started. The stepping motor 8 can drive the threaded transmission rod 9 connected thereto to rotate. When the threaded transmission rod 9 rotates, the first movable maglev conveying short rail 5 and the second movable maglev conveying short rail 7 that are threadedly connected thereto but movably penetrated by the guide rod 10 will move on the outer surface of the threaded transmission rod 9. At this time, the first movable maglev conveying short rail 5 is moved away from between the first maglev conveying rail 2 and the second maglev conveying rail 4, and the second movable maglev conveying short rail 7 is moved to the position where the first movable maglev conveying short rail 5 originally was, for the subsequent movement of the sliding table 3. Then, the semi-finished mobile phone located above the first movable maglev conveying short rail 5 can be subjected to long-time processing by the robotic arm installed on one side of the first movable maglev conveying short rail 5. After that, the sliding table 3 moving along the first maglev conveying rail 2 will move to another first movable maglev conveying short rail 5 through the second movable maglev conveying short rail 7 connected to the first maglev conveying rail 2 at this time. When the processing of the semi-finished mobile phone is completed, the first movable maglev conveying short rail 5 can be pulled back to its original position by the stepping motor 8. Through the above technical solution, the situation of blockage in the mobile phone production line can be prevented.

[0029] At the middle position of the lower end surfaces of both the first movable maglev conveying short rail 5 and the second movable maglev conveying short rail 7, a planar conical positioning groove 11 is provided, and below the first movable maglev conveying short rail 5, a positioning motor 15 fixedly installed inside the maglev conveyor belt base 1 is provided; when the second movable maglev conveying short rail 7 is moved to the position where the first movable maglev conveying short rail 5 originally was, the positioning motor 15 will be started accordingly.

[0030] Above the positioning motor 15, there is an internal thread groove 12. Inside the internal thread groove 12, there is an external thread positioning post 13 that matches its internal thread. In the middle position of the lower end face of the external thread positioning post 13, there is a square transmission groove 17. Inside the square transmission groove 17, there is a square rotating shaft 16 inserted, and the lower end face of the square rotating shaft 16 is connected to the output shaft of the positioning motor 15 through a coupling; the cross-sectional shape of the inner wall of the square transmission groove 17 is square, the outer surface of the square rotating shaft 16 fits with the inner wall of the square transmission groove 17, and the square rotating shaft 16 is slidably connected with the square transmission groove 17; the top end of the external thread positioning post 13 is a flat cone 14, and the shape of the flat cone 14 corresponds to the shape of the inner wall of the flat cone positioning groove 11; by driving the connected square rotating shaft 16 to rotate through the positioning motor 15, since the outer surface of the square rotating shaft 16 fits with the inner wall of the square transmission groove 17 located at the lower end face of the external thread positioning post 13, when the square rotating shaft 16 rotates, the external thread positioning post 13 will rotate along with it. When the external thread positioning post 13 rotates, under the transmission of the internal thread in the internal thread groove 12, the rotating external thread positioning post 13 will move up and down accordingly. At this time, when moving the external thread positioning post 13 upward, as the external thread positioning post 13 rises, the flat cone 14 located at the top end of the external thread positioning post 13 will gradually enter the inside of the flat cone positioning groove 11 located at the lower end face of the second mobile magnetic levitation conveying short rail 7. If the second mobile magnetic levitation conveying short rail 7 that moves is not completely aligned with the first magnetic levitation conveying rail 2, the position of the second mobile magnetic levitation conveying short rail 7 can be adjusted by the push of the flat cone 14. Through the above technical solution, the alignment accuracy between the second mobile magnetic levitation conveying short rail 7 and the first magnetic levitation conveying rail 2 can be improved.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description.
