Description

Technical Field

[0001] This application relates to the field of conveying technology, and particularly to a conveyor line. Background Art

[0002] With the development of society, logistics conveyor lines are widely used in various industries. By using conveyor lines to move workpieces, the time for workers to transfer workpieces can be shortened, thereby improving the efficiency of production and processing.

[0003] Generally, a conveyor line includes a plurality of stators and at least one rotor. The plurality of stators are arranged in a specific direction to define the movement path of the rotor. Some conveyor lines are also provided with a bifurcation part, and the rotor can be branched into different movement paths at the bifurcation part.

[0004] In some conveyor lines in the related art, permanent magnets are provided on the rotor, and coils extending to different movement paths are provided at the bifurcation part. When the rotor moves to the bifurcation part, by energizing a coil on one side, a magnetic attraction force is generated between the coil and the permanent magnet on the rotor. Under the guiding action of this magnetic attraction force, the rotor will be guided to the corresponding movement path, thereby realizing the switching of the movement path. However, for a conveyor line adopting this structure, there are relatively strict limiting conditions for the weight of the rotor, the size of the permanent magnet, the distance between the permanent magnet and the coil, etc., which makes the control difficult and the commutation efficiency low.

[0040] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the following further details the present application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] In the description of the present application, it should be understood that if there are terms such as "upper", "lower", "left", "right", etc. indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, it is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0042] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as implying or indicating relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0043] In the description of the present application, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0044] In some conveyor lines in the related art, a permanent magnet is provided on the mover, and coils extending to different movement paths are provided at the bifurcation part. When the mover moves to the bifurcation part, by energizing a coil on one side, a magnetic attraction force is generated between the coil and the permanent magnet on the mover. Under the guiding action of this magnetic attraction force, the mover will be guided into the corresponding movement path, thereby realizing the switching of the movement path. However, for the conveyor line with this structure, there are relatively strict limiting conditions for the weight of the mover, the size of the permanent magnet, the distance between the permanent magnet and the coil, etc., which makes the control difficult and the commutation efficiency low.

[0045] Based on the above situation, the embodiment of the present application proposes a conveyor line, aiming to provide a relatively simple and easy-to-implement structure for switching the movement path of the mover, so as to reduce the control difficulty and improve the commutation efficiency.

[0046] Figure 1 Schematic diagram of the structure of the conveyor line provided by an embodiment of the present application; Figure 2 Schematic diagram of the structure of the conveyor line provided by an embodiment of the present application from another perspective (bottom perspective of the conveyor line); Figure 3 For Figure 2 Enlarged schematic diagram of part A in Figure 4 For Figure 2 Enlarged schematic diagram of part B in. As Figures 1 to 4As shown in the figure, the conveyor line 1 in the embodiment of the present application includes a mover 10, a switching stator 20, a commutation assembly 30, and a transfer mechanism 60. The switching stator 20 includes a first conveying end 21, a second conveying end 22, and a third conveying end 23. A first conveying path 24 is formed between the first conveying end 21 and the second conveying end 22, and a second conveying path 25 is formed between the first conveying end 21 and the third conveying end 23. The commutation assembly 30 includes a guiding member 31 and a driving member 32. The driving member 32 is connected to the guiding member 31 to drive the guiding member 31 to move between a first position and a second position. The guiding member 31 has a first guiding portion 311 and a second guiding portion 312. When the guiding member 31 is in the first position, the first guiding portion 311 can guide the mover 10 to move along the first conveying path 24. When the guiding member 31 is in the second position, the second guiding portion 312 can guide the mover 10 to move along the second conveying path 25. The transfer mechanism 60 is used to transfer the workpiece 2 to the mover 10.

[0047] Among them, the switching stator 20 is arranged at the bifurcation of the conveyor line 1 to realize the diversion or confluence of the movement paths. That is to say, one movement path can be divided into multiple movement paths after passing through the switching stator 20, or multiple movement paths can converge into one movement path after passing through the switching stator 20. Exemplarily, in Figure 2 the shown conveyor line 1, there are two switching stators 20, which are respectively Figure 2 the switching stators 20 shown in part A and part B in Figure 2 In the structure shown in part A in Figure 3 , the guiding member 31 is in the first position (please refer to Figure 2 ). In Figure 4 the structure shown in part B in

[0048] the guiding member 31 is in the second position (please refer to Figure 4 ).

[0048] Specifically, the switching stator 20 includes a first conveying end 21, a second conveying end 22, and a third conveying end 23. A first conveying path 24 is formed between the first conveying end 21 and the second conveying end 22, and a second conveying path 25 is formed between the first conveying end 21 and the third conveying end 23. The second conveying end 22 and the third conveying end 23 can lead to different movement paths. In this way, when the mover 10 passes through the switching stator 20, it can be switched to the corresponding movement path.

[0049] The commutation assembly 30 includes a guide member 31 and a driving member 32. The driving member 32 is used to drive the guide member 31 to move. The guide member 31 has a first guiding portion 311 and a second guiding portion 312. It can be understood that both the first guiding portion 311 and the second guiding portion 312 guide the mover 10 in a contacting manner. That is to say, when the guide member 31 is in the first position, the mover 10 contacts the first guiding portion 311 during the process of passing through the switching stator 20, and thus is guided by the first guiding portion 311, so that the mover 10 moves along the first conveying path 24; when the guide member 31 is in the second position, the mover 10 contacts the second guiding portion 312 during the process of passing through the switching stator 20, and thus is guided by the second guiding portion 312, so that the mover 10 moves along the second conveying path 25.

[0050] The transplanting mechanism 60 is used to transfer the workpiece 2 to the mover 10. That is to say, the transplanting mechanism 60 can transfer the workpiece 2 from the storage position to the mover 10, so as to facilitate the conveying of the workpiece 2 by the conveying line 1. In this way, compared with manually transferring the workpiece 2, it is more time-saving and labor-saving.

[0051] In the conveying line 1 in the embodiment of the present application, a commutation assembly 30 is provided. By making the guide member 31 in the commutation assembly 30 be in the first position or the second position, the first guiding portion 311 or the second guiding portion 312 guides the mover 10, so as to guide the mover 10 onto different conveying paths, thereby realizing the selection and switching of the movement path of the mover 10. This way of guiding the mover 10 by contacting the mover 10 has fewer limiting conditions compared with the way of guiding the mover 10 by coils and permanent magnets. Therefore, the control difficulty is lower and it is relatively easy to implement. In addition, because this contact guiding method has better stability, a faster commutation speed can also ensure stable commutation. Therefore, it is also beneficial to improve the commutation efficiency.

[0052] It can be understood that the conveying line 1 further includes at least one track stator 70. Each track stator 70 is provided with a conveying path. The track stator 70 can be connected to the switching stator 20. When the number of track stators 70 is multiple, the multiple track stators 70 can be connected in sequence to construct the movement path of the mover 10. Among them, the track stator 70 can have different forms. For example, it can be linear or curved. Different forms of track stators 70 can be combined together, so as to form diverse movement paths.

[0053] The transplanting mechanism 60 can be arranged close to the track stator 70, especially close to the linear track stator 70. In this way, it is beneficial to reduce the difficulty of the transplanting mechanism 60 transferring the workpiece 2 to the mover 10.

[0054] Figure 5 ForFigure 2 Schematic diagram of one of the switching stators in the conveyor line shown; Figure 6 is Figure 2 Schematic diagram of another switching stator in the conveyor line shown. As Figures 3 to 6 shown, in some embodiments, the driving member 32 includes a main body portion 321 and a telescopic portion 322 connected to the main body portion 321. The telescopic portion 322 is connected to the guiding member 31 to drive the guiding member 31 to move along a linear trajectory. The switching stator 20 includes a stator body 26 and a guide rail 27 connected to the stator body 26. The guide rail 27 defines a first conveying path 24 and a second conveying path 25. When the guiding member 31 is in the first position, the first conveying path 24 is in a conducting state. When the guiding member 31 is in the second position, the second conveying path 25 is in a conducting state.

[0055] The driving member 32 includes a main body portion 321 and a telescopic portion 322 connected to the main body portion 321. It can be understood that the telescopic portion 322 can telescopically move relative to the main body portion 321, thereby driving the guiding member 31 to move along a linear motion trajectory. Exemplarily, the driving member 32 can be a device capable of outputting linear motion such as a cylinder, a hydraulic cylinder, an electric push rod, etc. In a preferred example, the driving member 32 is a cylinder, which has a relatively fast telescopic speed and stable operation, and is beneficial to improving the commutation speed of the commutation assembly 30.

[0056] The switching stator 20 includes a stator body 26 and a guide rail 27 connected to the stator body 26. The guide rail 27 can limit the motion trajectory of the mover 10 during the motion process. Therefore, the first conveying path 24 and the second conveying path 25 can be defined by the guide rail 27.

[0057] In addition, when the guiding member 31 is in the first position, the first conveying path 24 is in a conducting state, so that the guiding member 31 can smoothly move along the first conveying path 24. Similarly, when the guiding member 31 is in the second position, the second conveying path 25 is in a conducting state, so that the guiding member 31 can smoothly move along the second conveying path 25.

[0058] As Figures 3 to 6 shown, in some embodiments, the switching stator 20 further includes a first limiting member 41 and a second limiting member 42. The first limiting member 41 and the second limiting member 42 are fixed to the guide rail 27. When the guiding member 31 is in the first position, it abuts against the first limiting member 41. When the guiding member 31 is in the second position, it abuts against the second limiting member 42.

[0059] The first limiting member 41 and the second limiting member 42 are used to limit the guiding member 31. When the driving member 32 drives the guiding member 31 to move to the first position, the guiding member 31 abuts against the first limiting member 41. In this way, it can be ensured that the guiding member 31 can stop at the first position more precisely. Similarly, when the driving member 32 drives the guiding member 31 to move to the second position, the guiding member 31 abuts against the second limiting member 42. In this way, it can be ensured that the guiding member 31 can stop at the second position more precisely. Thus, the positioning accuracy of the guiding member 31 can be improved, and position deviation can be prevented.

[0060] Please refer to Figure 3 , in some embodiments, both the first limiting member 41 and the second limiting member 42 include a main body 411 and a blocking portion 412. The main body 411 is used to abut against the guiding member 31, and the blocking portion 412 is connected to one end of the main body 411 away from the guide rail 27.

[0061] Among them, the main body 411 is used to limit the guiding member 31. Specifically, when the guiding member 31 is in the first position, it abuts against the main body 411 of the first limiting member 41, and when the guiding member 31 is in the second position, it abuts against the main body 411 of the second limiting member 42. Thus, the positioning accuracy of the guiding member 31 is improved. On this basis, the first limiting member 41 and the second limiting member 42 are respectively provided with a blocking portion 412. The blocking portion 412 is connected to one end of the main body 411 away from the guide rail 27. When the guiding member 31 is in the first position, a part of the structure of the guiding member 31 is located between the guide rail 27 and the blocking portion 412 of the first limiting member 41. When the guiding member 31 is in the second position, a part of the structure of the guiding member 31 is located between the guide rail 27 and the blocking portion 412 of the second limiting member 42. In this way, through the blocking action of the blocking portion 412, it can be avoided that the guiding member 31 tilts or warps to the side away from the guide rail 27 due to factors such as gravity, which is beneficial to ensuring that the guiding member 31 can stably play a guiding role.

[0062] As Figures 3 to 6 shown, in some embodiments, the switching stator 20 further includes a buffer member 50. The buffer member 50 is located on the side of the guiding member 31 away from the driving member 32. The buffer member 50 is fixed to the guide rail 27, and the guiding member 31 contacts the buffer member 50 when it is in the first position.

[0063] The buffer member 50 is located on the side of the guiding member 31 away from the driving member 32. That is to say, during the extension process of the telescopic portion 322 of the driving member 32, the guiding member 31 will contact the buffer member 50. The buffer member 50 is used for buffering and limiting. Specifically, if the set stroke of the telescopic portion 322 is exactly equal to the movement stroke of the guiding member 31, when the guiding member 31 moves to the first position, it abuts against the buffer member 50 with a relatively small force. If the moving speed or weight of the mover 10 is relatively large, the set stroke of the telescopic portion 322 may also be relatively large correspondingly, such that the set stroke of the telescopic portion 322 may be greater than the movement stroke of the guiding member 31. In this case, there will be a relatively large abutting force between the guiding member 31 and the first limiting member 41. At this time, the buffer member 50 can protect the first limiting member 41. That is to say, the guiding member 31 contacts the buffer member 50 before contacting the first limiting member 41, and the buffer member 50 buffers and dissipates the force of the guiding member 31, thereby avoiding damage caused by excessive impact force between the guiding member 31 and the first limiting member 41.

[0064] Exemplarily, the buffer member 50 can be a device with a buffering function such as a spring or a buffer.

[0065] In some embodiments, the switching stator 20 has a first conveying path 24 and a second conveying path 25, that is, it has two conveying paths.

[0066] In some other embodiments, the switching stator 20 can also have a third conveying path, that is, it has three conveying paths. Specifically, the switching stator 20 further includes a fourth conveying end, and a third conveying path is formed between the first conveying end 21 and the fourth conveying end. The commutation assembly 30 further includes a second guiding member 31 and a second driving member 32, and the second driving member 32 is connected to the second guiding member 31 to drive the second guiding member 31 to move between a third position and a fourth position. Wherein, when the second guiding member 31 is in the third position, it can guide the mover 10 to move along the first conveying path 24, and when the second guiding member 31 is in the fourth position, it can guide the mover 10 to move along the third conveying path.

[0067] The third conveying path and the second conveying path 25 can be located on opposite sides of the first conveying path 24. Exemplarily, the third conveying path and the second conveying path 25 can be symmetrically arranged with respect to the center line of the first conveying path 24, or the third conveying path and the second conveying path 25 can be arranged in a staggered manner along the extending direction of the first conveying path 24.

[0068] Based on the case where the switching stator 20 has three conveying paths, the commutation assembly 30 further includes a second guiding member 31 and a second driving member 32. The second driving member 32 is used to drive the second guiding member 31 to move. When the second guiding member 31 is in the third position, it can guide the mover 10 to move along the first conveying path 24, and when the second guiding member 31 is in the fourth position, it can guide the mover 10 to move along the third conveying path. With such a setting, by controlling the movement of the guiding member 31 and the second guiding member 31, the mover 10 can be selectively guided into one of the three conveying paths.

[0069] Figure 7 The structural schematic diagram of the mover provided by an embodiment of the present application is as Figure 7 shown. In some embodiments, the mover 10 includes a mover body 11 and rollers 12. The rollers 12 are rotatably arranged on the mover body 11, and the mover body 11 is provided with a permanent magnet array 13. The switching stator 20 includes a stator body 26 and a guide rail 27 connected to the stator body 26. The stator body 26 is provided with an armature winding, and the armature winding is used for magnetic coupling with the permanent magnet array 13 to drive the mover 10 to move, and the rollers 12 cooperate with the guide rail 27.

[0070] By coupling the armature winding with the permanent magnet array 13, the mover 10 can be driven to move. During the movement of the mover 10, the rollers 12 of the mover 10 roll on the guide rail 27. On the one hand, the guide rail 27 can provide a guiding function for the mover 10 during the movement of the mover 10. On the other hand, the mover 10 is supported on the guide rail 27 through the rollers 12, so that the mover 10 can move relatively stably.

[0071] In one of the embodiments, the number of the rollers 12 is multiple. A part of the rollers 12 are first rollers 121, and another part of the rollers 12 are second rollers 122. The first rollers 121 are configured to roll along the top surface of the guide rail 27, and the top surface of the guide rail 27 is the surface of the guide rail 27 close to the stator body 26. The second rollers 122 are configured to roll along the side surface of the guide rail 27. Among them, the second rollers 122 are also used to abut against the first guiding portion 311 or the second guiding portion 312, so as to move along the first conveying path 24 under the guiding action of the first guiding portion 311, or move along the second conveying path 25 under the guiding action of the second guiding portion 312.

[0072] It can be understood that the setting directions of the first rollers 121 and the second rollers 122 are different. Exemplarily, the axle of the first rollers 121 is arranged in the horizontal direction, and the wheels of the second rollers 122 are arranged in the vertical direction, so that the first rollers 121 can be supported on the top surface of the guide rail 27, and the second rollers 122 can be supported on the side surface of the guide rail 27.

[0073] By providing the first roller 121 and the second roller 122, the mover 10 is supported by the guide rail 27 in both the horizontal and vertical directions. Thus, the mover 10 can move more stably during the movement process.

[0074] In addition, when the guide member 31 is in the first position, the mover 10 abuts against the first guiding portion 311 and rolls along the first guiding portion 311 during the process of passing through the switching stator 20; when the guide member 31 is in the second position, the mover 10 abuts against the second guiding portion 312 and rolls along the second guiding portion 312 during the process of passing through the switching stator 20. It can be seen that the second roller 122 can also form a supporting effect with the guide member 31, enabling the mover 10 to move relatively stably during the commutation process.

[0075] In one of the embodiments, the mover 10 further includes a carrying portion 14, which is connected to the mover body 11 and is used for carrying the workpiece 2 to be conveyed. In this way, the conveyance of the workpiece 2 can be realized through the movement of the mover 10.

[0076] Please refer to Figure 6 , in some embodiments, the switching stator 20 includes a stator body 26 and a guide rail 27 connected to the stator body 26. The guide rail 27 defines a first conveying path 24 and a second conveying path 25. The guide rail 27 is formed with a first guiding surface 271, and the second guiding portion 312 has a second guiding surface 3121. Both the first guiding surface 271 and the second guiding surface 3121 are arc-shaped surfaces. When the guide member 31 is in the second position, the second guiding surface 3121 is tangent to the side surface of the guide rail 27 located on one side of the first conveying path 24, and the second guiding surface 3121 is also tangent to the first guiding surface 271.

[0077] When the guide member 31 is in the second position, one end of the second guiding surface 3121 is tangent to the side surface of the guide rail 27 located on one side of the first conveying path 24, and the other end of the second guiding surface 3121 is tangent to the first guiding surface 271 formed on the guide rail 27, which makes the transition between the second guiding surface 3121 and the guide rail 27 smooth. In this way, when the mover 10 is guided by the second guiding portion 312 and enters the second conveying path 25, no obvious vibration or jitter will occur, which is beneficial to improving the movement stability of the mover 10.

[0078] In one of the embodiments, the plane where the end face of the first conveying end 21 is located and the plane where the end face of the third conveying end 23 is located have a first intersection line, and the centers of the first guiding surface 271 and the second guiding surface 3121 are both located on the first intersection line.

[0079] With such a setting, the second guiding surface 3121 is tangent to the first guiding surface 271 and has the same curvature as the first guiding surface 271. In this way, when the mover 10 is guided to the second conveying path 25, it can move along an arc trajectory with a constant radius of curvature. This is beneficial to keeping the mover 10 moving at a constant speed, thus making the movement of the mover 10 more stable.

[0080] Figure 8 The structural schematic diagram of the transplanting mechanism provided by an embodiment of the present application is as follows. Figure 1 、 Figure 8 As shown, in some embodiments, the transplanting mechanism 60 includes a lifting component 61, a transplanting component 62, and a carrier 63. The carrier 63 is used to carry the workpiece 2. The carrier 63 is connected to the transplanting component 62, and the transplanting component 62 is connected to the lifting component 61. The lifting component 61 is used to change the height of the carrier 63, and the transplanting component 62 is used to approach the mover 10 and place the workpiece 2 on the mover 10.

[0081] The process of the transplanting mechanism 60 transferring the workpiece 2 to the mover 10 is as follows: The lifting component 61 drives the carrier 63 to lift and lower, so that the carrier 63 and the mover 10 are at the same height position. Then the transplanting component 62 approaches the mover 10, and the carrier 63 carrying the workpiece 2 moves to the carrying part 14 of the mover 10. Then the lifting component 61 drives the carrier 63 to descend, so that the workpiece 2 falls on the carrying part 14 of the mover 10. After that, the transplanting component 62 retracts, and the lifting component 62 returns to the original height to prepare for transferring a new workpiece 2 next time.

[0082] Specifically, the transplanting component 62 is a translation device that can drive the carrier 63 to move horizontally. Thus, the transplanting component 62 can approach the mover 10 and deliver the carrier 63 to the carrying part 14 of the mover 10.

[0083] In some embodiments, the workpiece 2 can be a wafer cassette or a silicon wafer cassette. The conveying line 1 in the embodiments of the present application can replace the intelligent cart in the traditional wafer factory. That is, the mover 10 carries the wafer cassette or the silicon wafer cassette. Compared with the traditional intelligent cart, the mover 10 has the characteristics of being lighter and having a smaller weight, thus reducing the track load. And the conveying line in the present application has the function of lane splitting and merging. As Figure 1 shown, the conveying line 1 is provided with a separate lane for obtaining / interacting with the wafer cassette, without affecting the conveyance of other movers in the main lane, thereby improving the conveying efficiency.

[0084] In other embodiments, as Figure 1As shown, the transplanting mechanism 60 can also be used to unload the workpiece 2 from the mover 10. That is, the mover 10 only bears the transportation function. After the mover 10 travels along the main path to a shunt fork in front of a certain process equipment, it turns into this branch path, and then transfers the workpiece 2 to the transplanting mechanism 60. Subsequently, the mover 10 flows back to the main path through the branch path and enters the next process. Thereby, the conveying efficiency and process efficiency are improved.

[0085] In some embodiments, the conveying line 1 in the embodiments of the present application can be arranged inside a semiconductor wafer fabrication plant. The transplanting module can be arranged above the EFEM (Equipment Front End Module) position and is used to be responsible for handing over the wafer cassette with the equipment EFEM. During the movement process, the mover 10 does not need to bear the movement of the EFEM. Thus, the load of the mover 10 is reduced. After the mover 10 runs to the designated position, the transplanting mechanism 60 realizes the operation on the workpiece 2.

[0086] The above content is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
