[0003] In the actual application of a plurality of parallel magnetic suspension conveying lines, it is often necessary to transfer the workpieces on one conveying line to another conveying line.

When the mover carrying the workpieces is moved to the second conveying line, the transfer device is returned to the first conveying line to connect the first conveying line.

[0055] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0056] Figure 1 The diagram shows a top-view illustration of the connection process between two conveyor lines in the prior art. The carriers 230 on adjacent conveyor lines move in the same direction. The first conveyor line 310 is the main conveyor line, and the second conveyor line 320 is a branch line of the first conveyor line 310. The two conveyor lines lead to different target positions. For example, taking this conveyor system as an example in the field of workpiece processing, the first conveyor line 310 connects the upstream and downstream processes. Under normal circumstances, after the carrier 230 is processed in the upstream process, it is normally conveyed from left to right to the downstream process position by the first conveyor line 310. At this time, the connection device is docked in the first conveyor line 310. If a defective product is found in the upstream process, it needs to be transferred from the first conveyor line 310 to the second conveyor line 320 and discharged from the conveyor system via the second conveyor line 320 to avoid it flowing into the downstream process and causing adverse effects. After the carrier 230 carries the defective product to the connecting device, the connecting device moves the carrier 230 from the position docked with the first conveyor line 310 to the position docked with the second conveyor line 320, so that the carrier 230 can be moved from the connecting device to the second conveyor line 320, and the defective product is discharged from the normal processing conveying system by the second conveyor line 320.

[0057] Understandably, during the connection process (moving from the position docked with the first conveyor line 310 to the position docked with the second conveyor line 320) and the return process (moving from the position docked with the second conveyor line 320 to the position docked with the first conveyor line 310), the first conveyor line 310 is disconnected. For the first conveyor line 310 with a large conveying capacity, this seriously affects the normal flow of qualified products during the process of conveying defective products to the second conveyor line 320, causing congestion of the carrier component 230 on the first conveyor line 310, thereby affecting the overall conveying efficiency and processing efficiency.

[0058] Therefore, the embodiments of the first aspect of this application propose a connection device, such as... Figure 3 As shown, the connecting device includes a connecting guide rail 100 and multiple transfer mechanisms 200. The connecting guide rail 100 is used to connect various conveyor lines in series. The transfer mechanism 200 is slidably connected to the connecting guide rail 100 and can move along the length of the connecting guide rail 100, thereby enabling it to connect with different conveyor lines. It should be noted that the transfer mechanism 200 includes a connecting base 210 and a connecting guide rail 220. The connecting base 210 is slidably connected to the connecting guide rail 100, and the connecting guide rail 220 is rotatably connected to the connecting base 210. The connecting guide rail 220 is used to support the carrier 230, and the connecting guide rail 220 can connect with the conveyor rail on the conveyor line, so that the carrier 230 can move from the conveyor rail on the conveyor line to the connecting guide rail 220, or from the connecting guide rail 220 to the conveyor rail.

[0059] Based on the above structure, the connection device has at least a first connection mode and a second connection mode for the user to select. When the connection device is in the first connection mode, each transfer mechanism 200 moves in the same direction so that the carrier 230 can move with the connection guide rail 220 until the connection guide rail 220 is connected with the next conveying line in the moving direction, so that the carrier 230 can be moved to the next conveying line.

[0060] Specifically, taking the embodiment shown in Figure 4 for example, the number of transfer mechanisms 200 is consistent with the number of conveying lines, and in the initial state, one transfer mechanism 200 of the connection device is connected with the first conveying line 310 (for the convenience of subsequent description, this transfer mechanism 200 is named as the first transfer mechanism 201), and the other transfer mechanism 200 is idle (for the convenience of subsequent description, this transfer mechanism 200 is named as the second transfer mechanism 202), when the carrier 230 on the first conveying line 310 needs to be transferred to the second conveying line 320, after the carrier 230 moves to the first transfer mechanism 201, the first transfer mechanism 201 and the second transfer mechanism 202 move synchronously towards the direction of the second conveying line 320, so that the first transfer mechanism 201 is connected with the second conveying line 320, and the second transfer mechanism 202 is connected with the first conveying line 310. Further, when the first transfer mechanism 201 conveys the carrier 230 to the second conveying line 320, the first conveying line 310 can also keep the state of being connected by means of the second transfer mechanism 202, without causing congestion of other carriers 230 on the first conveying line 310.

[0061] It can be understood that in other embodiments (not shown in the figure), the number of transfer mechanisms 200 can also be more than the number of conveying lines, for example, referring to the embodiment of Figure 4 , the connection device includes three transfer mechanisms 200, i.e., the first transfer mechanism 201, the second transfer mechanism 202 and the third transfer mechanism 200, along the direction from the first conveying line 310 to the second conveying line 320, the second transfer mechanism 202 is idle, the first transfer mechanism 201 is connected with the first conveying line 310, and the third transfer mechanism 200 is connected with the second conveying line 320, when the three transfer mechanisms 200 move in the same direction, the second transfer mechanism 202 is connected with the first conveying line 310, the first transfer mechanism 201 is connected with the second conveying line 320, and the third transfer mechanism 200 is idle. In this embodiment, when there is no carrier 230 on the first conveying line 310 that needs to be transferred to the second conveying line 320, the second conveying line 320 can also keep the state of being connected, so as to convey the carrier 230 on the second conveying line 320.

[0062] When the transfer device is in the second transfer mode, the transfer rails 220 of the adjacent conveying lines are rotated and docked to enable the carriers 230 to move onto the transfer rails 220 of the next conveying line and return with the rotation of the transfer rails 220 until the transfer rails 220 are docked with the next conveying line, and then the carriers 230 move onto the next conveying line.

[0063] Specifically, taking the embodiment shown in Figure 5 the number of transfer mechanisms 200 on the transfer device is consistent with the number of conveying lines, in the initial state, one transfer mechanism 200 of the transfer device is docked with the first conveying line 310 (for the convenience of subsequent description, this transfer mechanism 200 is named as the first transfer mechanism 201), and the other transfer mechanism 200 is docked with the second conveying line 320 (for the convenience of subsequent description, this transfer mechanism 200 is named as the second transfer mechanism 202), when the carriers 230 on the first conveying line 310 need to be transferred to the second conveying line 320, after the carriers 230 move onto the first transfer mechanism 201, the first transfer mechanism 201 and the second transfer mechanism 202 rotate, it can be understood that the rotating actions of the first transfer mechanism 201 and the second transfer mechanism 202 can occur simultaneously or sequentially.

[0064] When the first transfer mechanism 201 and the second transfer mechanism 202 rotate to the conveying directions of the transfer rails 220 of the two mechanisms coincide, the first transfer mechanism 201 and the second transfer mechanism 202 move towards each other to dock the two mechanisms, so that the carriers 230 can move from the transfer rail 220 of the first transfer mechanism 201 to the transfer rail 220 of the second transfer mechanism 202, and then the first transfer mechanism 201 and the second transfer mechanism 202 move away from each other until they return to the positions corresponding to the conveying lines, and then the first transfer mechanism 201 and the second transfer mechanism 202 return and rotate to connect the first conveying line 310 and the second conveying line 320. It can be understood that compared with the prior art in which a single transfer mechanism 200 transfers the carriers 230 between two conveying lines, the speed of the transfer in the present application is greatly improved by using two transfer mechanisms 200 that can be docked.

[0065] For example, when both transfer mechanisms 200 move towards each other and the distance of the movement towards each other is equal, the movement stroke of each transfer mechanism 200 of the transfer device is shortened by half, and the transfer efficiency is doubled. In other embodiments, for example, Figure 8As shown, considering that the conveying amount on the first conveying line 310 is greater than the conveying amount of the second conveying line 320, thereby, after the first transfer mechanism 201 and the second transfer mechanism 202 are rotated to coincide with the conveying directions of the connection rails 220, the first transfer mechanism 201 that is in butt joint with the first conveying line 310 remains stationary, and the second transfer mechanism 202 is close to the first transfer mechanism 201, thereby reducing the moving stroke of the first transfer mechanism 201 and reducing the line breakage time of the first conveying line 310.

[0066] It should be explained that, in the process of rotating the first transfer mechanism 201 and the second transfer mechanism 202 to coincide with the conveying directions of the connection rails 220 of the two, as shown in Figure 5 and Figure 6 As shown, the connection rails 220 of the first transfer mechanism 201 and the connection rails 220 of the second transfer mechanism 202 can rotate in the same direction or in the opposite direction, which is specifically adapted according to the conveying directions of the connection rails 220 and the conveying lines.

[0067] As shown in Figure 3 It should be explained that the connection device in the figure includes two transfer mechanisms 200, and in other specific embodiments, the number of transfer mechanisms 200 can be specifically adjusted according to the number of conveying lines. As can be understood, in the embodiment shown in Figure 4 to Figure 8 As shown, the conveying lines are parallel and arranged in parallel, and the connection rails 100 extend perpendicular to the conveying lines, and in other embodiments, since the connection rails 220 of the connection device of the present application can rotate relative to the connection base 210, the conveying lines can also be arranged at a certain angle, and the connection rails 100 can be arranged at an arbitrary angle.

[0068] Based on the above, the connection device of the present application has two connection modes, whether it is the first connection mode that shortens the line breakage time of the conveying line through the compensation position, or the second connection mode that shortens the connection stroke of the transfer mechanism 200, which can shorten the line breakage time of the conveying line, reduce the congestion probability of the conveying line, and improve the conveying efficiency of the conveying line. And, based on the rotatable connection between the connection rails 220 and the connection base 210, the connection device can adapt to different connection modes according to specific application scenarios, and can be applied to conveying systems in which the conveying lines and the connection rails 100 intersect at an acute angle or an obtuse angle.

[0069] As shown in Figure 2 It is a connection process schematic diagram of the prior art connection device, which is shown from the perspective of top view. In Figure 2In the embodiment, the two conveying lines are arranged side by side, and the conveying directions of the two conveying lines are opposite, that is, the moving directions of the carrier 230 on the first conveying line 310 and the second conveying line 320 are opposite, the connecting device is arranged at one end of the conveying line, when the carrier 230 on the first conveying line 310 is conveyed to the right to the connecting device, the connecting device supports the carrier 230 to translate until it is connected with the second conveying line 320, so as to convey the carrier 230 to the second conveying line 320. It should be noted that the carrier 230 is marked with a triangle, and the triangle is located at the front end of the carrier 230. It should be explained that the triangle is to facilitate the reader to more clearly see the change of the moving posture of the carrier 230, and should not be considered as a limitation of the scheme of the present application.

[0070] In the prior art as shown in Figure 2 When the carrier 230 moves on the first conveying line 310, the direction from the rear end to the front end of the carrier 230 is the same as the conveying direction of the first conveying line 310, when the carrier 230 moves on the second conveying line 320, the direction from the rear end to the front end of the carrier 230 is opposite to the conveying direction of the second conveying line 320, the moving posture of the carrier 230 changes, because the moving posture of the workpiece is consistent with the carrier 230, therefore, the moving postures of the workpiece on the first conveying line 310 and the second conveying line 320 are different. On the one hand, the wind resistance, friction and the like change during the movement of the workpiece, on the other hand, the clamping point of the workpiece changes when it is discharged, and needs to be adjusted again.

[0071] Therefore, in order to solve the problem of different moving postures in the prior art, the posture of the carrier 230 is adjusted during the connection process in the embodiment, so that when the connecting guide rail 220 is connected with the conveying guide rail of the second conveying line 320, the direction from the rear end to the front end of the carrier 230 is the same as the conveying direction of the second conveying line 320 when it moves. Specifically, as shown in Figure 7 When the carrier 230 is located on the connecting guide rail 220, the connecting guide rail 220 rotates relative to the connecting base 210, so that the moving postures of the carrier 230 on the first conveying line 310 and the second conveying line 320 are the same.

[0072] It should be explained that in Figure 7Only one transfer mechanism 200 is shown, and it can be understood that in the first connection mode, only the transfer mechanism 200 carrying the carrier 230 needs to be rotated by 180 degrees, and the remaining transfer mechanisms 200 do not need to be rotated synchronously. In the second connection mode, the rotation directions of the first transfer mechanism 201 and the second transfer mechanism 202 are adjusted, so that the first transfer mechanism 201 carrying the carrier 230 is rotated by 90 degrees and then connected with the second transfer mechanism 202, and the second transfer mechanism 202 carrying the carrier 230 continues to rotate by 90 degrees in the same direction and then connects with the second conveying line 320. In the connection process, the adjustment of the workpiece moving posture is completed.

[0073] In some embodiments, the connection device includes a first driving member, a second driving member, and a third driving member. The first driving member is used to drive the connection base 210 to slide relative to the connecting guide rail 100. The second driving member is used to drive the connection guide rail 220 to rotate relative to the connection base 210. The third driving member is used to drive the carrier 230 to move relative to the connection guide rail 220. The first driving member, the second driving member, and the third driving member can be linear motors, air cylinders, lead screws, magnetic drive structures, etc. Preferably, the first driving member is a linear motor, the second driving member is a DD motor, and the third driving member is a magnetic drive structure, which includes a magnetic drive stator arranged on the connection guide rail 220 and a magnetic drive rotor arranged on the carrier 230.

[0074] It can be understood that the overall structure of the linear motor is relatively flat, so that the entire connection device is more compact and occupies less space. In addition, since the first driving member needs to drive the connection base 210, the connection guide rail 220, the carrier 230, and the workpiece to move relative to the connecting guide rail 100, the load is large. Therefore, selecting a linear motor is beneficial to the stable and accurate movement of the above-mentioned components, and is also beneficial to ensuring the connection accuracy of the connection guide rail 220. In addition, the second driving member adopts a DD motor, which has the advantages of large torque, large load, and flat structure, and is suitable for the application scenario of the embodiments of the application. The third driving member adopts a magnetic drive structure. The magnetic field of the magnetic drive stator on the connection guide rail 220 changes and interacts with the magnetic field of the magnetic drive rotor on the carrier 230, thereby driving the carrier 230 to move, so as to realize the high-speed, high-precision, and high-flexibility operation of the carrier 230.

[0075] In some embodiments, as Figure 8As shown, when the connecting device is in the second connecting mode, according to the amount of the first conveying line 310 and the second conveying line 320, different docking schemes can be selected, so as to further improve the conveying efficiency of each conveying line. For example, if the conveying amount of the first conveying line 310 and the second conveying line 320 is similar, the two connecting rails 220 of the adjacent conveying lines are rotated, and then the two transfer mechanisms 200 move towards each other to realize docking and transition of the carrier 230. If the conveying amount of the first conveying line 310 is greater than that of the second conveying line 320, the first transfer mechanism 201 corresponding to the first conveying line 310 does not move after rotation, and the second transfer mechanism 202 corresponding to the second conveying line 320 moves close to the first transfer mechanism 201 and docks.

[0076] In some embodiments, the conveying lines are arranged in sequence along the horizontal direction, and the connecting rail 100 extends along the horizontal direction to connect the conveying lines in series. Each conveying line is arranged in the horizontal plane, which is beneficial to arranging the loading and unloading positions on both sides of each conveying line. Alternatively, the conveying lines are arranged in sequence along the vertical direction, and the connecting rail 100 extends along the vertical direction to connect the conveying lines in series, thereby facilitating reduction of the floor space occupied by the conveying system.

[0077] In some embodiments, the transfer mechanism 200 further comprises an adjusting member connected with the connecting base 210 and the connecting rail 220, respectively, to adjust the distance between the connecting rail 220 and the connecting base 210. Specifically, taking the example of the conveying lines arranged in sequence along the horizontal direction, if the heights of the conveying rails of the conveying lines are different, the distance between the connecting rail 220 and the connecting base 210 can be adjusted by the adjusting member to adjust the height of the connecting rail 220, so as to dock with conveying rails of different heights.

[0078] In some embodiments, the connecting rail 100 is provided with a first limiting part, and the connecting base 210 is provided with a second limiting part. The first limiting part and the second limiting part cooperate to limit the displacement of the connecting base 210 relative to the connecting rail 100. It can be understood that the first limiting part can be a limiting protrusion, and the second limiting part can also be a limiting protrusion, so that the first limiting part and the second limiting part abut to limit the relative movement of the connecting base 210 and the connecting rail 100. In the embodiments of the present application, the first limiting part is an induction slot 110 as shown in the drawings, and the second limiting part is an induction blocking piece 240. When the induction blocking piece 240 is inserted into the induction slot 110 with the movement of the connecting base 210, the controller issues an instruction to limit the further movement of the connecting base 210.

[0079] ​The embodiment of the second aspect of the application provides a conveying system, which comprises a plurality of conveying lines and the transfer device mentioned in any one of the above embodiments, and the transfer device is used for transfer connection of the carrying member 230 on each conveying line. It can be understood that, since the transfer efficiency of the transfer device is high, the conveying system has a short line waiting time and high conveying efficiency.

[0080] The embodiment of the third aspect of the application provides a transfer method, which is applied to the conveying system mentioned above. As shown in the figure, Figure 9 The transfer method comprises the following steps:

[0081] S100, acquiring current position information of the carrying member 230 needing to be transferred;

[0082] It can be understood that the transfer mechanism 200 is also provided with a position sensor, which is used for sensing the position information and the rotation angle of the carrying member 230. It can be understood that, in combination with the magnetic drive sub on the carrying member 230 and the magnetic drive sub on the transfer guide rail 220, the position sensor can respond to the magnetic field signal to acquire the current position information of the carrying member 230, or the position information can be acquired through a photoelectric sensor, an infrared sensor and the like.

[0083] S200, acquiring target position information of the carrying member 230;

[0084] It can be understood that the target position information of the carrying member 230 can be acquired according to the scanning of the trace code on the workpiece, for example, after the workpiece has undergone an upstream processing procedure, the trace code on the workpiece is scanned, and it is acquired that the next procedure needs to be performed, so that the carrying member 230 is conveyed to a processing position of the next procedure through the conveying system. The target position information of the carrying member 230 can also be obtained through a preset program of the controller, or through a new instruction of the controller.

[0085] S300, planning a transfer mode of the transfer device based on the current position information and the target position information to realize transfer connection of the carrying member 230 between the conveying lines.

[0086] Specifically, as shown in the figure, Figure 10 In step S300, the following steps are further included:

[0087] S310, planning a conveying path of the carrying member 230 in combination with layout information of each conveying line;

[0088] Understandably, in addition to considering current and target location information, the layout information of each conveyor line can also be taken into account. Specifically, the layout information can include the arrangement sequence, angle, track height, and location of connecting devices of each conveyor line, thereby planning the shortest conveying path for the carrier 230. Furthermore, the current conveying volume on each conveyor line can be combined to rationally plan the conveying path of the carrier 230 to avoid congested sections.

[0089] S320. Based on the layout information of the conveyor lines on the conveying path, plan the moving distance and / or rotation angle of the connecting device.

[0090] Understandably, when the control connection device is in the first connection mode, the moving distance of the connection device needs to be set according to the spacing of the conveyor line. When the control connection device is in the second connection mode, the rotation angle of the connection guide rail 220 needs to be set according to the intersection angle between the conveyor guide rail of the conveyor line and the connection guide rail 220 of the connection device.

[0091] Furthermore, step S320 also includes the following steps:

[0092] S321. Based on the movement attitude information at the target location, plan the rotation angle of the connecting device.

[0093] Understandably, reference Figure 7 As shown, if there are requirements for the movement posture of the workpiece, the carrier 230 needs to be rotated during the connection process to ensure that the movement posture of the workpiece remains consistent on different conveyor lines.

[0094] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
