Description

Technical Field

[0001] The present application relates to the technical field of conveyor lines, and in particular to a transport device. Background Art

[0002] With the development of society, logistics conveyor lines are widely used in various industries. Using conveyor lines to move workpieces can shorten the time it takes to transfer workpieces between workers and increase production processing speed. Overhead cranes are a key automated handling system in semiconductor manufacturing plants. They use cranes sliding on elevated tracks to automatically transport materials. This system can significantly improve material transportation efficiency, reduce labor costs, and minimize contamination risks, thereby improving the overall production process.

[0003] In related technologies, an overhead crane conveying system includes a conveyor line, a crane, a carrier, and a control system. The conveyor line is installed on the factory ceiling to move the crane. The crane moves along the conveyor line, and a carrier is fixed to the crane to place materials on the carrier. The control system controls the crane's movement to achieve material transportation. However, during the transportation process, the crane is usually equipped with a power supply system to provide power to the crane. This can easily cause the crane to be heavy and require a large amount of power during transportation, resulting in low transportation efficiency of the conveying system. Utility Model Content

[0035] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] In the technology of related overhead crane conveying systems, the trolley generally needs to be equipped with a lifting mechanism. On the one hand, the lifting mechanism needs to be powered, and a power supply track is usually set up in the conveying system to supply power to the trolley and the lifting mechanism. On the other hand, the installation of a lifting mechanism easily makes the trolley heavier, and greater power is required during the conveying process.

[0037] For the above situation, please see Figure 1-Figure 4 The present application proposes a transport device 1, including a mover 10, a conveyor line assembly 20 and a transfer assembly 30. The mover 10 has a load-bearing cavity 13, which can carry a workpiece 2. The mover 10 moves on the conveyor line assembly 20 to transport the workpiece 2 carried in the load-bearing cavity 13.

[0038] The conveyor line assembly 20 is magnetically coupled with the mover 10 and drives the mover 10 to move. The conveyor line assembly 20 includes a main conveyor line 21, an auxiliary conveyor line 22 and a switching stator 23. The main conveyor line 21 and the auxiliary conveyor line 22 are arranged at an angle. For example, the main conveyor line 21 and the auxiliary conveyor line 22 are perpendicular to each other and are arranged at right angles.

[0039] like Figure 2As shown, the switching stator 23 is arranged between the main conveying line 21 and the auxiliary conveying line 22, that is, the switching stator 23 is arranged at the bifurcation between the main conveying line 21 and the auxiliary conveying line 22, which can realize the diversion or merging of the motion path of the mover 10. After passing through the switching stator 23, one motion path of the mover 10 can be divided into multiple motion paths, or, multiple motion paths of the mover 10 can be merged into one motion path after passing through the switching stator 23.

[0040] Specifically, such as Figure 1 As shown, the switching stator 23 includes a first conveying end 231, a second conveying end 232 and a third conveying end 233. A first conveying path is formed between the first conveying end 231 and the second conveying end 232, and a second conveying path is formed between the first conveying end 231 and the third conveying end 233. The first conveying path coincides with the extension direction of the main conveying line 21, and the second conveying path extends from the main conveying line 21 to the direction of the auxiliary conveying line 22. The first conveying path and the second conveying path are both used to supply the mover 10 with movement, wherein the first conveying path and the second conveying path can lead to different motion paths so that the mover 10 can switch to different motion paths in the process of passing through the switching stator 23.

[0041] like Figure 5 As shown, the transfer component 30 is arranged adjacent to the auxiliary conveyor line 22. The transfer component 30 includes a control component 31 and a transfer component 32. The control component 31 is electrically connected to the transfer component 32. The control component 31 is used to drive the transfer component 32 to transfer the workpiece 2 to the carrying cavity 13, or the control component can also drive the transfer component 32 to take out the workpiece 2 in the carrying cavity 13. It is easy to understand that the transfer component 30 can play a role in loading or unloading the mover 10. For example, the mover 10 is transported on the main conveyor line 21. During the transportation process, the mover 10 can change the movement path by switching the stator 23, and then load or unload on the auxiliary conveyor line 22, and finally return to the main conveyor line 21 through the switching stator 23 to continue transportation.

[0042] Among them, the working path of the transfer member 32 can be set according to actual conditions. For example, the storage position of the workpiece 2 is located below the auxiliary conveyor line 22. At this time, the transfer member 32 can slide vertically to transfer the workpiece 2; for another example, the storage position of the workpiece 2 is located on the side of the auxiliary conveyor line 22. At this time, the transfer member 32 can slide horizontally to transfer the workpiece 2; for another example, the workpiece 2 is provided with storage points below and on the side of the auxiliary conveyor line 22. At this time, the transfer member 32 can slide vertically and the transfer member 32 can also slide horizontally, making the transfer of the workpiece 2 more convenient, and the setting of the transfer component 30 is more time-saving and labor-saving than manually transferring the workpiece 2. In addition, the transfer component 30 in this embodiment can also be set so that the transfer member 32 transfers the workpiece 2 in any direction, changing the way the workpiece 2 is loaded from a fixed single direction, so that the transfer component 30 can transfer the workpiece 2 set at various positions, further improving the convenience of transferring the workpiece 2.

[0043] It should be noted that the main conveyor line 21 and the auxiliary conveyor line 22 are both formed by splicing multiple track stators 221. The first conveying end 231 can be connected to the track stator 221 on the main conveyor line 21, and the third conveying end 233 can be connected to the track stator 221 on the auxiliary conveyor line 22. The workpiece 2 can be a wafer box or a silicon wafer box. The conveyor line assembly 20 in the embodiment of the present application can replace the overhead crane conveyor line in a traditional wafer factory, and the mover 10 can replace the smart car in a traditional wafer factory, that is, the mover 10 carries the wafer box or silicon wafer box. In the embodiment of the present application, the mover 10 and the transfer assembly 30 are separately provided. After the mover 10 reaches the designated position on the auxiliary conveyor line 22, the transfer assembly 30 can transfer the workpiece 2 set at various positions to the mover 10, making the transfer of the workpiece 2 more convenient. At this time, the mover 10 can only assume the function of conveying the workpiece 2. Compared with the traditional smart car, the mover 10 has a smaller overall mass, is lighter, and has a faster speed, thereby reducing the track load and improving the efficiency during transportation. At the same time, the conveyor line assembly 20 in the present application has a lane-dividing and merging function. A separate auxiliary conveyor line 22 is provided in the conveyor line assembly 20 to divide the lanes for the mover 10 to obtain or exchange wafer boxes, which does not affect the transportation of other movers 10 in the main conveyor line 21, thereby further improving the transportation efficiency.

[0044] See Figure 3In some embodiments of the present application, the main conveyor line 21 and the auxiliary conveyor line 22 each include at least one track stator 221, the track stator 221 is magnetically coupled with the mover 10, and each track stator 221 is provided with a conveying path. The track stator 221 can be connected to the switching stator 23. When there are multiple track stators 221, multiple track stators 221 can be spliced ​​in sequence to construct the motion path of the mover 10. Among them, the track stator 221 can have different forms, for example, a straight line or a curved line, and track stators 221 of different forms can be combined together to form a variety of motion paths. The transfer component 30 can be arranged close to the track stator 221, especially close to the straight track stator 221, so that it is helpful to reduce the difficulty of the transfer component 30 to transfer the workpiece 2 to the mover 10.

[0045] Among them, a first socket 2211 is opened on the track stator 221, and the first socket 2211 can be used to plug in the power cord and the optical fiber. The power cord can transmit electrical energy to the track stator 221 and the armature winding in the switching stator 23, and the optical fiber can transmit signals to the track stator 221 and the switching stator 23. At the same time, the first socket 2211 is opened on the side of the track stator 221 away from the mover 10, which not only facilitates the cable plugging, but also avoids the first socket 2211 being set on the side and interfering with the mover 10 and other components.

[0046] Please continue to see Figure 3 In some embodiments of the present application, the transfer assembly 30 includes a first moving member 33 and a second moving member 34. The first moving member 33 and the second moving member 34 are both provided with a control member 31 and a transfer member 32. The transfer member 32 on the first moving member 33 can move vertically to transfer the workpiece 2, and the transfer member 32 on the second moving member 34 can move horizontally to transfer the workpiece 2. The first moving member 33 and the second moving member 34 are both arranged adjacent to the auxiliary conveyor line 22. The first moving member 33 and the second moving member 34 are separate and spaced apart. The transfer member 32 on the first moving member 33 is the first transfer member, and the transfer member 32 on the second moving member 34 is the second transfer member. In other words, the first transfer member and the second transfer member are completely independently provided, and their movements do not affect each other, thereby avoiding interference between the workpiece 2 during horizontal and vertical movements. At the same time, the first moving part 33 and the second moving part 34 are separately and independently arranged, that is, the first transfer part and the second transfer part can separately transfer the workpiece 2 at different positions, thereby increasing the range of the workpiece 2 that can be transferred by the transportation device, and can more flexibly adapt to workpieces 2 of various specifications, thereby improving the transportation diversity of the transportation device 1.

[0047] Alternatively, in some embodiments, the first moving member 33 and the second moving member 34 are provided in combination, that is, the first moving member 33 and the second moving member 34 are connected, and the first transport member and the second transport member are kinematically coupled. In this case, the second transport member can first obtain the workpiece 2 from where the workpiece 2 is placed, and then the workpiece 2 is transported by the second transport member and approaches the first transport member until the workpiece 2 is transferred to the first transport member, thereby allowing the first transport member to transport the workpiece 2 to the mover 10 on the auxiliary conveyor line 22. The combination of the first moving member 33 and the second moving member 34 can increase the transportation range of the workpiece 2 and make the placement of the workpiece 2 more flexible and changeable.

[0048] In some embodiments, the first moving member 33 includes a first track (not shown in the figure) extending in the vertical direction, and the transfer member 32 is connected to the first track in a vertical sliding manner to transfer the workpiece 2 vertically. The second moving member 34 includes a second track (not shown in the figure) extending in the horizontal direction, and the transfer member 32 is connected to the second track in a horizontal sliding manner to transfer the workpiece 2 horizontally. When the first moving member 33 and the second moving member 34 are separate and spaced apart, the first track and the second track are separated, and when the first moving member 33 and the second moving member 34 are combined, the first track is connected to the second track. It is easy to understand that this embodiment limits the moving position and direction of the transfer member 32 by setting a track for the transfer member 32 to move, so that the movement of the transfer member 32 is more regular and the transfer member 32 is prevented from being displaced during movement.

[0049] Among them, the transfer component 30 can be a fork mechanism, which realizes the transfer of the workpiece 2 by the fork mechanism, and the drive of the fork mechanism can be realized by belt transmission, linear motor transmission or pneumatic mechanism. Therefore, the transfer component 30 can be at least one of belt transmission, linear motor transmission and pneumatic transmission. It can be understood that the first track and the second track and the transfer member 32 can be transmitted by only one of the above three transmission methods, or they can be combined in pairs, or the three transmission methods can be combined with each other to transmit together. Taking the transfer member 32 and the first track as an example of belt transmission, the first track can include a motor and a synchronous belt, and a friction block can be set on the transfer member 32. The motor is used to drive the synchronous belt to move. The friction block on the transfer member 32 and the synchronous belt frictionally cooperate, so that the movement of the synchronous belt can drive the movement of the friction block, and then drive the transfer member 32 to move.

[0050] See Figure 4 In some embodiments of the present application, the mover 10 includes a mover 10 body and a clamp 12. The mover 10 body is connected and magnetically coupled to the conveyor line assembly 20. The clamp 12 is arranged on the mover 10 body. The clamp 12 and the mover 10 body together form a bearing cavity 13.

[0051] Specifically, when the mover 10 moves on the auxiliary conveyor line 22 to a position close to the transfer assembly 30, the transfer member 32 can directly transfer the workpiece 2 to the bearing cavity 13. At this time, the clamp 12 on the main body of the mover 10 can clamp the workpiece 2, that is, the clamp 12 can provide a clamping force for the transportation of the workpiece 2 to ensure the transportation stability of the workpiece 2. A blocking portion 15 can be provided on the side of the clamp 12 away from the main body of the mover 10 (that is, the bottom of the clamp 12). After the clamp 12 clamps the workpiece 2, the blocking portion 15 at the bottom of the clamp 12 can contact the bottom of the workpiece 2, thereby preventing the workpiece 2 from falling out of the bearing cavity 13. Among them, the mover 10 also includes a permanent magnet array 14 arranged on the main body of the mover 10. The permanent magnet array 14 is magnetically coupled with the armature winding on the track stator 221 or the switching stator 23, thereby driving the mover 10 to move on the conveyor line assembly 20.

[0052] In some embodiments of the present application, the transfer component 30 also includes a sensor (not shown in the figure) arranged on the transfer member 32, and the sensor is electrically connected to the control member 31. The sensor is used to detect the distance from the mover 10 to the transfer member 32. The sensor is also used to transmit the detected data to the control member 31 so that the control member 31 drives the transfer member 32 to work.

[0053] It is easy to understand that when the sensor detects that the distance between the mover 10 and the transfer member 32 reaches a preset value, the sensor transmits the relevant data signal to the control member 31, so that the control member 31 drives the transfer member 32 to move, so that when the mover 10 reaches the designated position on the auxiliary conveying line 22, the transfer member 32 can promptly transfer the workpiece 2 to the bearing cavity 13 of the mover 10, thereby reducing the waiting time of the mover 10 and improving the conveying efficiency of the workpiece 2 in the transport device 1. Among them, a reflective strip can be set on the mover 10 to reflect the signal emitted by the sensor so that the sensor can detect the distance between the mover 10 and the transfer member 32; the preset value of the distance from the mover 10 to the transfer member 32 can be set according to actual conditions; the designated position of the mover 10 on the auxiliary conveying line 22 refers to the position where the transfer member 32 transfers the workpiece 2 to the bearing cavity 13 of the mover 10.

[0054] See Figure 5-Figure 7 In some embodiments of the present application, the transport device 1 further includes a reversing assembly 40, which is disposed on the main conveying line 21 or the auxiliary conveying line 22. The reversing assembly 40 includes a connecting member 41 and a driving member 42, and the driving member 42 is connected to the connecting member 41 to drive the connecting member 41 to move between the first position and the second position.

[0055] Furthermore, the switching stator 23 includes a stator body 234 and a guide rail (not shown in the figure) connected to the stator body 234. The guide rail can limit the movement trajectory of the mover 10 during movement. Therefore, the guide rail can define a first conveying path and a second conveying path. When the connector 41 is in the first position, the connector 41 connects the guide rail and the main conveying line 21, the first conveying path is in a conducting state, and the mover 10 can move on the main conveying line 21 via the first conveying path; when the connector 41 is in the second position, the guide rail and the auxiliary conveying line 22 are connected, the second conveying path is in a conducting state, and the mover 10 can move from the main conveying line 21 to the auxiliary conveying line 22 via the second conveying path.

[0056] In some embodiments, as Figure 7 As shown, the stator body 234 includes a first split 2341 and a second split 2342, the two ends of the first split 2341 are respectively the first conveying end 231 and the second conveying end 232, and the two ends of the first split 2341 are connected to the two main conveying lines 21, the first end of the second split 2342 is connected to the middle part of the first split 2341, the second end of the second split 2342 is the third conveying end 233, and the other end of the second split 2342 is connected to the auxiliary conveying line 22.

[0057] For example, the first split 2341 is in a straight line, the second split 2342 is in an arc shape, and the connecting member 41 is also in a straight line. When the connecting member 41 is in the first position, the connecting member 41 is located at the first end of the second split 2342, that is, the two ends of the connecting member 41 are respectively connected to the two main conveying lines 21, so that the guide rail and the main conveying line 21 are connected to form a complete movement path through the connecting member 41, and at this time the connecting member 41 will block the second conveying path leading to the second split 2342, thereby providing a guiding role for the movement of the mover 10, so that the mover 10 The mover 10 can only move on the main conveying line 21 via the first conveying path; when the connecting member 41 is in the second position, the connecting member 41 leaves the second split 2342. At this time, the middle part of the first split 2341 is connected to the second split 2342, and due to the existence of the second split 2342, the guide rail and the main conveying line 21 are disconnected. When the mover 10 moves from the main conveying line 21 to the middle part of the first split 2341 on the switching stator 23, the mover 10 will move to the second conveying path under the guidance of the second split 2342, and move toward the auxiliary conveying line 22.

[0058] It should be noted that when the connecting member 41 is in the first position, it can block the second conveying path, thereby guiding the mover 10 to move on the first conveying path. When the connecting member 41 is in the second position, it can avoid the second conveying path and disconnect the connection between the guide rail and the main conveying line 21, so that the mover 10 moves on the second conveying path. The connecting member 41 switches its position to guide the mover 10 to different conveying paths, thereby selecting and switching the movement path of the solid line mover 10. Compared with the method of guiding the mover 10 through coils and permanent magnets, this method does not have too many restrictions, so the control difficulty is lower and it is easier to implement. In addition, since this guiding method has better stability, setting the commutation speed faster can also stabilize the commutation, so it is also beneficial to improve the commutation efficiency.

[0059] Furthermore, in some embodiments, Figure 1 As shown, the main conveyor line 21 and the auxiliary conveyor line 22 are arranged vertically, the reversing component 40 is arranged on the auxiliary conveyor line 22, and the driving member 42 drives the connecting member 41 to move along a straight line trajectory, thereby reducing the movement difficulty of the reversing component 40, making the movement of the connecting member 41 simpler and more stable, and also conducive to improving the reversing efficiency.

[0060] Furthermore, in some embodiments of the present application, the reversing assembly 40 also includes a first limit member and a second limit member (not shown in the figure), and the first limit member and the second limit member are both fixed on the auxiliary conveying line 22; wherein, when the connecting member 41 is in the first position, the connecting member 41 abuts against the first limit member, and when the connecting member 41 is in the second position, the connecting member 41 abuts against the second limit member.

[0061] Specifically, the first and second position-limiting members are used to limit the position of the connecting member 41. When the driving member 42 drives the connecting member 41 to the first position, the connecting member 41 abuts the first position-limiting member, thereby ensuring that the connecting member 41 can be relatively accurately stopped in the first position. Similarly, when the driving member 42 drives the connecting member 41 to the second position, the connecting member 41 abuts the second position-limiting member, thereby ensuring that the connecting member 41 can be relatively accurately stopped in the second position. This improves the positioning accuracy of the connecting member 41 and prevents positional deviation.
