Description

Technical Field

[0001] This invention relates to the field of magnetic drive conveying technology, and in particular to a conveying device. Background Technology

[0002] In fields such as automated conveying and precision manufacturing, magnetic drive conveyor systems have become core equipment for material transfer and positioning due to their advantages such as stable operation and precise positioning. A magnetic drive conveyor system consists of a mover and a track. The mover carries materials on the track for transport, and uses vacuum adsorption to fix the products in place, ensuring the stability of the conveying process.

[0003] In existing technologies, a vacuum generator is typically integrated onto the mover and powered to achieve vacuum adsorption of the product. Currently, there are two power supply methods: one is wired power supply, which uses a sliding contact line or cable chain to power the vacuum generator. This method is prone to power supply instability due to friction and bending of the lines, poses safety hazards, limits the mover's movement flexibility, and increases installation and maintenance costs. The other is wireless power supply, which uses a track-side transmitting coil and a mover-side receiving coil to transmit electrical energy to power the vacuum generator. However, this requires matching the mover's speed and position to ensure power supply efficiency, and is costly, involves energy loss, and the electromagnetic signal may interfere with precision components, affecting positioning accuracy. Furthermore, integrating the vacuum generator onto the mover leads to a more complex mover structure, increased weight, and reduced transmission efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a conveying device to address the issue that the mover needs to be additionally integrated with a vacuum generator and powered to achieve vacuum adsorption and fixation of products.

[0005] A conveying device, comprising:

[0006] The mover includes a bearing surface for bearing materials. The mover has a plurality of adsorption holes that penetrate the bearing surface. The mover also has a first air passage that communicates with the plurality of adsorption holes. The mover is used to move along a preset conveying route to convey the materials.

[0007] The negative pressure track has a negative pressure chamber, and the extension direction of the negative pressure chamber is consistent with the preset conveying route of the mover;

[0008] A negative pressure generating element, wherein the negative pressure generating element is connected to the negative pressure chamber;

[0009] A gas-converting mechanism is configured to move with the mover, and one end of the gas-converting mechanism is slidably and sealed within the negative pressure chamber. The gas-converting mechanism has a second air passage that maintains communication between the negative pressure chamber and the first air passage.

[0010] In one embodiment, the negative pressure track is further provided with an opening that extends in the same direction as and communicates with the negative pressure chamber. A first sealing element is also provided on the negative pressure track. The first sealing element has a connecting part and a covering part. The connecting part is connected to the negative pressure track, and the covering part can cover or open the opening. One end of the gas transfer mechanism enters the negative pressure chamber through the opening.

[0011] In one embodiment, a partition is provided in the negative pressure chamber, the extension direction of the partition is the same as the extension direction of the negative pressure chamber, so as to isolate the negative pressure chamber into an independent first chamber and a second chamber. The negative pressure generating element is connected to the first chamber, the opening is connected to the second chamber, and a through hole is provided through the partition, the through hole connecting the first chamber and the second chamber.

[0012] In one embodiment, the negative pressure track includes:

[0013] The track body has the aforementioned negative pressure chamber;

[0014] A support leg assembly for supporting the track body, the support leg assembly having a mounting end connected to the track body, the support leg assembly being placed on a mounting plane, and the distance between the mounting end and the mounting plane being adjustable.

[0015] In one embodiment, the outrigger assembly includes:

[0016] The support rod has the aforementioned mounting end;

[0017] A base is placed on the mounting plane, and the support rod is slidably connected to the base so that the distance between the mounting end and the mounting plane is adjustable.

[0018] In one embodiment, the gas-converting mechanism is fixed to the moving part so that the gas-converting mechanism and the moving part move together.

[0019] In one embodiment, a second seal is provided between the gas-converting mechanism and the moving part to make the gas-converting mechanism and the moving part sealed together.

[0020] In one embodiment, the moving part is recessed with a receiving groove, the receiving groove is connected to the first air passage, the other end of the air-changing mechanism is located in the receiving groove, and a second sealing element is provided between the receiving groove and the air-changing mechanism.

[0021] In one embodiment, the negative pressure generator is a vacuum pump.

[0022] In one embodiment, the conveying device further includes:

[0023] A magnetic drive transport track is provided with a drive component, which includes an armature winding for magnetic coupling with the mover to drive the mover to move along the magnetic drive transport track. A negative pressure track is provided on the outer or inner side of the magnetic drive transport track.

[0024] The aforementioned conveying device, by setting up a negative pressure track and a negative pressure generating element independent of the mover, and by connecting the negative pressure chamber of the negative pressure track with the adsorption hole of the mover through a gas conversion mechanism, allows the negative pressure generated by the negative pressure generating element to be transmitted to the adsorption hole of the mover. There is no need to integrate a vacuum generating device on the mover, nor is there a need for an additional power supply. The mover only needs to have an adsorption hole and a first air passage, which simplifies the structure of the mover, reduces the weight of the mover itself, makes the movement of the mover more flexible and convenient, and improves the transmission efficiency. The gas conversion mechanism moves with the mover, and one end of it is sealed and slidably connected to the negative pressure chamber, so that the movement of the mover is not restricted and the stability of the connection between the negative pressure chamber and the adsorption hole can be guaranteed.

[0042] like Figures 1-3 As shown, this application provides a conveying device, which includes a mover 1, a negative pressure track 2, a negative pressure generator 3, and a gas conversion mechanism 4. The mover 1 includes a bearing surface 11 for bearing materials. The mover 1 has a plurality of adsorption holes 12 that penetrate the bearing surface 11. The mover 1 also has a first air passage 13 that communicates with the plurality of adsorption holes 12. The mover 1 is used to move along a preset conveying route to convey materials. The negative pressure track 2 has a negative pressure chamber 21. The extension direction of the negative pressure chamber 21 is consistent with the preset conveying route of the mover 1. The negative pressure generator 3 is connected to the negative pressure chamber 21. The gas conversion mechanism 4 is configured to move with the mover 1, and one end of the gas conversion mechanism 4 is sealed and slidably connected to the negative pressure chamber 21. The gas conversion mechanism 4 has a second air passage 41 that maintains communication between the negative pressure chamber 21 and the first air passage 13.

[0043] The negative pressure generator 3 is connected to the negative pressure chamber 21 of the negative pressure track 2. The operation of the negative pressure generator 3 creates a negative pressure environment in the negative pressure chamber 21. The air transfer mechanism 4 can move with the mover 1. One end of the air transfer mechanism 4 is sealed and slidably located in the negative pressure chamber 21. The second air passage 41 of the air transfer mechanism 4 maintains the connection between the negative pressure chamber 21 and the first air passage 13 of the mover 1. The first air passage 13 of the mover 1 is connected to several adsorption holes 12 that penetrate the bearing surface 11. The negative pressure in the negative pressure chamber 21 can be transmitted to the adsorption holes 12 through the second air passage 41 and the first air passage 13. When the bearing surface 11 of the mover 1 carries the material, the adsorption holes 12 generate an adsorption force due to the negative pressure, thereby fixing the material on the bearing surface 11, effectively preventing the material from shaking, shifting or even falling off during the conveying process, and ensuring the stability of the material conveying.

[0044] This conveying device uses an independent negative pressure track 2 and a negative pressure generator 3, and connects the negative pressure chamber 21 of the negative pressure track 2 with the adsorption hole 12 of the mover 1 through a gas transfer mechanism 4. This allows the negative pressure generated by the negative pressure generator 3 to be transmitted to the adsorption hole 12. There is no need to integrate a vacuum generator on the mover 1, nor is there an additional power supply. The mover 1 only needs to have an adsorption hole 12 and a first air passage 13, which simplifies the structure of the mover 1, reduces its weight, makes the movement more flexible and convenient, and improves the transmission efficiency. The gas transfer mechanism 4 moves with the mover 1, and one end of it is sealed and slidably connected in the negative pressure chamber 21, so that the movement of the mover 1 is not restricted and the stability of the connection between the negative pressure chamber 21 and the adsorption hole 12 can be guaranteed.

[0045] It should be noted that the number and arrangement of the adsorption holes 12 are not limited and can be set freely and flexibly according to the needs of the material to be fixed.

[0046] In some optional embodiments, the mover 1 has a chamber that communicates with a plurality of adsorption holes 12, and the chamber is also connected to a first air passage 13, thereby enabling the first air passage 13 to communicate with all of the adsorption holes 12. In other optional embodiments, the plurality of adsorption holes 12 are interconnected, with one of the adsorption holes 12 communicating with the first air passage 13, thereby enabling the first air passage 13 to communicate with all of the adsorption holes 12.

[0047] Optionally, such as Figure 2 , Figure 3As shown, the negative pressure track 2 also has an opening 22, which extends in the same direction as the negative pressure chamber 21 and communicates with it. A first sealing element 23 is also provided on the negative pressure track 2. The first sealing element 23 has a connecting part and a covering part. The connecting part is connected to the negative pressure track 2, and the covering part can cover or open the opening 22. One end of the gas-converting mechanism 4 enters the negative pressure chamber 21 through the opening 22. The gas-converting mechanism 4 can enter the negative pressure chamber 21 through the opening 22, so that the negative pressure chamber 21 communicates with the second air passage 41. The covering part of the first sealing element 23 can fit against the gas-converting mechanism 4 and the negative pressure track 2 during the movement of the gas-converting mechanism 4 to achieve dynamic sealing. Even if the gas-converting mechanism 4 moves continuously along the direction of the opening 22, the first sealing element 23 can automatically adjust its shape according to the positional changes of the gas-converting mechanism 4, better ensuring the airtightness of the negative pressure chamber 21, thereby ensuring a continuous and stable negative pressure environment within the negative pressure chamber 21.

[0048] In some alternative embodiments, such as Figure 3 As shown, there are two first sealing elements 23. The connecting parts of the two first sealing elements 23 are respectively located on both sides of the opening 22 on the negative pressure track 2, and the covering parts of the two first sealing elements 23 together cover the opening 22. During the movement of the air transfer mechanism 4, the two first sealing elements 23 can work together and adjust their shape according to the position and movement state of the air transfer mechanism 4 to achieve a better sealing structure with the air transfer mechanism 4, ensuring good airtightness of the negative pressure chamber 21.

[0049] Optionally, such as Figure 2 , Figure 3 As shown, a partition 24 is provided in the negative pressure chamber 21. The extension direction of the partition 24 is the same as the extension direction of the negative pressure chamber 21, so as to isolate the negative pressure chamber 21 into an independent first chamber 211 and a second chamber 212. The negative pressure generating element 3 is connected to the first chamber 211, and the opening 22 is connected to the second chamber 212. A through hole 241 is provided on the partition 24, which connects the first chamber 211 and the second chamber 212. The negative pressure generator 3 is directly connected to the first chamber 211, causing the first chamber 211 to generate negative pressure. The negative pressure is then transmitted to the second chamber 212 through the through hole 241, and then to the second air passage 41. After the negative pressure chamber 21 is divided into the first chamber 211 and the second chamber 212 by the partition 24, the first chamber 211 focuses on sealing the connection with the negative pressure generator 3, and the second chamber 212 focuses on sealing the opening 22. This disperses the risk of sealing failure and ensures a stable negative pressure environment in the negative pressure chamber 21, thereby improving the stability of the conveying device.

[0050] It should be noted that the number and position of the through holes 241 are set according to actual needs, and are not limited in this embodiment.

[0051] Optionally, such as Figure 1 , Figure 2 As shown, the negative pressure track 2 includes a track body 25 and a support leg assembly 26. The track body 25 has the aforementioned negative pressure chamber 21. The support leg assembly 26 supports the track body 25 and has a mounting end connected to the track body 25. The support leg assembly 26 is placed on a mounting plane, and the distance between the mounting end and the mounting plane is adjustable. The adjustable support leg assembly 26 can easily adjust the track body 25 to a suitable height for good docking and cooperation with other components, such as conveyor belts and conveyor tracks in a conveying device.

[0052] In some optional embodiments, there are multiple support leg assemblies 26, which are spaced apart along the extension direction of the negative pressure track 2. By setting multiple support leg assemblies 26 to jointly support the track body 25, when a single support leg assembly 26 fails, other support leg assemblies 26 can still provide support, preventing significant damage. When the installation plane is not level, each support leg assembly 26 can be adjusted to make the track body 25 level.

[0053] Optionally, such as Figure 2 As shown, the support leg assembly 26 includes a support rod 261 and a base 262. The support rod 261 has the aforementioned mounting end, and the base 262 is placed on the mounting plane. The support rod 261 is slidably connected to the base 262 so that the distance between the mounting end and the mounting plane is adjustable.

[0054] In some optional embodiments, the support rod 261 is threaded, and the base 262 is correspondingly provided with a threaded hole. The distance between the mounting end and the mounting plane can be changed by adjusting the screw depth of the support rod 261. In another optional embodiment, the support rod 261 is slidably located within the base 262. The support leg assembly 26 also includes a locking element, such as a bolt or screw. Both the support rod 261 and the base 262 are provided with oblong holes or a set of spaced threaded holes. The locking element is passed through the corresponding oblong hole or threaded hole to fix the support rod 261 to the base 262. When it is necessary to adjust the distance between the mounting end and the mounting plane, the locking element is released and the support rod 261 is slid.

[0055] In some alternative embodiments, the gas-converting mechanism 4 is driven by a drive mechanism, and its speed, trajectory and other parameters are exactly the same as those of the mover 1, so that the gas-converting mechanism 4 moves with the mover 1.

[0056] In other alternative embodiments, such as Figure 4 As shown, the gas-converting mechanism 4 is fixed to the moving element 1 so that the gas-converting mechanism 4 moves with the moving element 1. The gas-converting mechanism 4 is fixed to the moving element 1 and can be completely synchronized with the movement of the moving element 1, thereby enabling the gas-converting mechanism 4 to stably transmit the negative pressure of the negative pressure track 2 to the moving element 1, so that the moving element 1 can stably adsorb materials.

[0057] Optionally, such as Figure 3 As shown, a second sealing element 5 is provided between the gas conversion mechanism 4 and the mover 1 to ensure a sealed connection between the gas conversion mechanism 4 and the mover 1. By providing the second sealing element 5, the connection between the first air passage 13 and the second air passage 41 can be well sealed, preventing fluctuations in the negative pressure at the adsorption hole 12 due to poor sealing at the connection, and ensuring that the mover 1 can stably adsorb materials.

[0058] In some alternative embodiments, such as Figure 3 As shown, the moving part 1 has a recessed receiving groove 14, which communicates with the first air passage 13. The other end of the air conversion mechanism 4 is located within the receiving groove 14, and a second sealing element 5 is provided between the receiving groove 14 and the air conversion mechanism 4. The recessed receiving groove 14 on the moving part 1 provides space for the air conversion mechanism 4, eliminating the need for complex alignment and adjustment during installation, thus ensuring the connection between the first and second pipes. On the other hand, it provides space for the second sealing element 5, ensuring that the second sealing element 5 can stably seal the connection between the air conversion mechanism 4 and the moving part 1.

[0059] Optionally, the negative pressure generating element 3 is a vacuum pump.

[0060] Optionally, such as Figure 1 As shown, this conveying device also includes a magnetic drive conveying track 6, on which a driving component is laid. The driving component includes an armature winding, which is used to magnetically couple with the mover 1 to drive the mover 1 to move along the magnetic drive conveying track 6. A negative pressure track 2 is set on the outer or inner side of the magnetic drive conveying track 6. The negative pressure track 2 is set on the outer or inner side of the magnetic drive conveying track 6, making full use of the space around the track and eliminating the need for a large amount of additional independent space to arrange the negative pressure system. The electric drive winding is magnetically coupled with the mover 1, providing power for the movement of the mover 1 on the magnetic drive conveying track 6. Compared with the traditional mechanical drive method, this reduces the contact and friction between moving parts, thereby reducing vibration and noise generation and realizing high-speed material conveying.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
