[0043] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0045] See also Figure 1-5 , the embodiment provided by the utility model:

[0046] like Figure 1 As shown, a segmented sequential carrier circulation system includes two linear modules 1 for connecting the carrier 2 to the upper and lower layers. The linear module 1 drives the carrier 2 connected to the lower layer to rise to the upper layer.

[0047] A multi-station bracket 3 is fixedly installed between the two linear modules 1. The multi-station bracket 3 is divided into area A, area B and area C. Areas A, B and C are all slidably connected to the carrier 2. The side wall of the multi-station bracket 3 is installed with a fork mechanism 5 for transferring the carrier 2 between areas A, B and C:

[0048] like Figure 2 As shown, the linear module 1 includes a linear guide 11, a slide 12, a fixed frame 13 and a mounting frame 14. The slide 12 is slidably connected to the side wall of the linear guide 11. The two linear guides 11 are vertically arranged at both ends of the multi-station bracket 3. The fixed frame 13 is installed on the side wall of the linear guide 11. The mounting frame 14 is fixed to the side wall of the slide 12 by screws. The top surface of the mounting frame 14 is installed with a slide rail 4, and the carrier 2 is slidably connected to the top surface of the mounting frame 14 through the slide rail 4.

[0049] The motor on the linear guide rail 11 drives the slide 12 to move up and down, so that the carrier 2 on the mounting frame 14 can move up and down, thereby being able to move and transfer the carrier 2 between the upper and lower layers of the processing platform.

[0050] The fork mechanism 5 reciprocates on the side wall of the multi-station bracket 3 through the station transfer drive mechanism 6, and the station transfer drive mechanism 6 is installed on the side wall of the multi-station bracket 3;

[0051] The workstation transfer drive mechanism 6 drives the fork mechanism 5 to move, so that the fork mechanism 5 drives the carrier 2 in areas A, B and C to move, so that the carrier 2 in area A can move 700mm to the right, and the carrier 2 reaches the first workstation in area A, so that the processing equipment performs the current 40s workstation operation on the workpiece on the carrier 2 in the first workstation in area A, and then the workstation transfer drive mechanism 6 drives the fork mechanism 5 to move, so as to move the carrier 2 on the workstation in area A to area B, and so on, so that the carrier 2 in areas A, B and C can be moved, so that the carrier 2 can be at different workstations, so that the workpiece on the carrier 2 can be processed by different equipment.

[0052] Specifically, such as Figure 4 As shown, the fork mechanism 5 includes a sliding assembly, a fork driving assembly and a rotating assembly installed on the side wall of the sliding assembly, and a docking assembly installed on the rotating assembly. The fork driving assembly drives the rotating assembly to rotate on the side wall of the sliding assembly, thereby causing the docking assembly to move in and out of the docking assembly 9 installed on the bottom surface of the carrier 2.

[0053] The specific structure of the fork mechanism 5 in this embodiment is as follows:

[0054] The sliding assembly includes a movable connecting plate 51, a first bearing seat 52, a first guide rail 7, and a slide 8. The side walls of the movable connecting plate 51 are fixedly mounted to at least three first bearing seats 52, and the slide 8 is fixedly mounted on the side wall of the movable connecting plate 51 near the multi-station bracket 3. The first guide rail 7 is fixedly mounted on the side wall of the multi-station bracket 3, and the slide 8 is slidably connected to the side wall of the first guide rail 7.

[0055] The movable connecting plate 51 is docked and installed with the two rotating components respectively through the first bearing seats 52 on the side walls.

[0056] By sliding the movable connecting plate 51 on the first guide rail 7 , the station transfer drive mechanism 6 can drive the fork mechanism 5 to move on the side wall of the multi-station bracket 3 , and at the same time, a mounting carrier for the fork mechanism 5 is provided by the first bearing seat 52 and the movable connecting plate 51 .

[0057] The fork drive assembly includes a cylinder 56 and a fixed block 54. The cylinder 56 is fixedly mounted on the side wall of the fixed connecting plate through a connecting frame. The piston end of the cylinder 56 is fixedly mounted to the fixed block 54 by screws. The side wall of the fixed block 54 is installed with a guide wheel 55. The rotating assembly includes a rotating rod 53, a fork plate 57 and a fork groove 58. The side wall of the rotating rod 53 is fixedly connected to the inner ring of at least three first bearing seats 52 installed on the side wall of the movable connecting plate 51. The side wall of the rotating rod 53 is fixedly mounted with a fork plate 57. The end of the fork plate 57 is provided with a fork groove 58, and the guide wheel 55 is located in the fork groove 58.

[0058] During specific operation, the cylinder 56 drives the fixed block 54 to move up and down, and then the guide wheel 55 located in the fork groove 58 also moves up and down, so that the guide wheel 55 slides in the fork groove 58, and drives the fork plate 57 to swing along the rotating rod 53 as the center of the circle and rise or fall according to the piston end of the cylinder 56, so that the rotating rod 53 can also rotate within the rotation range of the fork plate 57 to provide power for the docking assembly to move in and out.

[0059] like Figure 5 As shown, the docking assembly includes a fork follower 59 and a cam 591. The fork follower 59 is fixedly mounted on the end of the rotating rod 53, and the cam 591 is mounted on the top of the fork follower 59. The docking assembly 9 includes a limit frame 91 and a limit slot 92. The limit frame 91 is fixedly mounted on the bottom surface of the carrier 2, and the limit slot 92 is provided on the bottom surface of the limit frame 91. The cam 591 mounted on the top of the fork follower 59 rotates in and out of the limit slot 92.

[0060] The rotating rod 53 rotates within the rotation range of the fork plate 57, so that the fork follower 59 installed on the end can also float with the rotation of the fork plate 57, prompting the cam 591 to rotate in and out of the limit groove 92. When rotating in, the cam 591 is placed in the limit groove 92, so that when the fork mechanism 5 moves, it drives the carrier 2 to slide on the A area, B area and C area of ​​the multi-station bracket 3. When the cam 591 rotates out of the limit groove 92, the current carrier 2 stops moving at the designated station, so that the equipment at the station can process the workpiece on the carrier 2.

[0061] In order to ensure the stability of the rotating rod 53 during rotation, the side wall of the rotating rod 53 located outside the movable connecting plate 51 is also fixedly connected to the inner ring of the first bearing seat 52, and the side wall of the first bearing seat 52 is slidably connected on the second guide rail 10. The first bearing seat 52 restricts the part of the rotating rod 53 located outside the movable connecting plate 51, thereby ensuring the stable rotation of the fork follower 59 installed at the end of the rotating rod 53.

[0062] In order to facilitate the sliding of the carrier 2 on areas A, B and C of the multi-station bracket 3, a slide rail 4 is fixedly installed on the top surface of the multi-station bracket 3. The carrier 2 is slidably connected on the stations in areas A, B and C through the slide rail 4 to facilitate the transfer of the carrier 2.

[0063] As the specific structure of the station transfer drive mechanism 6 in this embodiment:

[0064] like Figure 4As shown, the workstation transfer drive mechanism 6 includes a servo motor 61, an active synchronous wheel 62, a synchronous belt 63, a driven synchronous wheel 64, a second bearing seat 65, a screw 66, a nut 67 and a connecting seat 68. The output shaft of the servo motor 61 is connected to the internal key of the active synchronous wheel 62, and the active synchronous wheel 62 is connected to the side wall of the driven synchronous wheel 64 through the synchronous belt 63. The end of the screw 66 is connected to the internal key of the driven synchronous wheel 64, and the two ends of the screw 66 are respectively fixedly connected to the inner ring of the second bearing seat 65. The second bearing seat 65 is installed on the side wall of the multi-station bracket 3. The inside of the nut 67 is threadedly connected to the side wall of the screw 66 located between the two second bearing seats 65. The bottom of the connecting seat 68 is fixedly connected to the side wall of the nut 67, and the top of the connecting seat 68 is fixedly installed with the side wall of the movable connecting plate 51 by screws.

[0065] The specific movement process is as follows: the servo motor 61 transmits the transmission between the active synchronous wheel 62, the synchronous belt 63, and the driven synchronous wheel 64, so that the screw rod 66 can rotate in the second bearing seat 65, so that the nut 67 moves on the side wall of the screw rod 66, and changes the movement direction according to the rotation direction of the screw rod 66, thereby driving the connecting seat 68 and the movable connecting plate 51 to move, so that the fork mechanism 5 can move on the side wall of the multi-station bracket 3, thereby enabling the carrier 2 to move from the mounting frame 14 of the linear module 1 to the A, B and C area stations of the multi-station bracket 3.

[0066] Specifically, when the carrier 2 on the workstation in area A needs to be transferred, the cylinder 56 of the fork mechanism 5 drives the cam 591 on the fork follower 59 to rotate into the limit groove 92, and then the workstation transfer drive mechanism 6 drives the fork mechanism 5 to slide on the first guide rail 7 and the second guide rail 10 respectively, so that the carrier 2 slides to area B. There are 17 carriers 2 in area B. The fork mechanism 5 drives the carrier 2 to move 500mm to the right to reach the first working position of the 17 workstations in area B. The positioning cylinder 56 on the carrier 2 drives the triangular positioning block to insert into the positioning profiling block of the carrier 2 to operate in the first position for 10s. At the same time, the cam 591 on the fork follower 59 of the fork mechanism 5 rotates out of the limit groove 92, and then the fork mechanism 5 drives the carrier 2 to move 500mm to the left again. Move the 17 carriers 2 in area B 100mm to the right and reach the second working position of the 17 workstations in area B. After 10s of operation, the workstation transfer drive mechanism 6 moves the 17 carriers 2 in area B 100mm to the right and reaches the third working position of the 17 workstations in area B. After 10s of operation, the workstation transfer drive mechanism 6 drives the fork mechanism 5 to move the 17 carriers 2 in area B 100mm to the right and reach the fourth working position of the 17 workstations in area B. After 10s of operation, the workstation transfer drive mechanism 6 and the fork mechanism 5 move the 17 carriers 2 in area B 200mm to the right, so that the carriers 2 in area B move one workstation to the right. The positioning cylinder 56 drives the triangular positioning block to insert into the positioning profiling block of the carrier 2. The servo motor 61 of the 17 workstations in area B drives the fork mechanism 5 to extend to the 5th workstation position in area A to start the next cycle.

[0067] The servo motors 61 of the five workstations in area C drive the fork mechanism 5 to extend to the fourth working position of the 17th workstation in area B. The unlocking cylinder 56 of the fork mechanism 5 at the 17th workstation in area B is opened. After the workstation operation is completed, areas A, B and C move synchronously.

[0068] Area A moves 700mm so that each carrier 2 on the 5 workstations in area A moves forward one workstation, Area B moves 200mm so that each carrier 2 on the 17 workstations in area B moves forward one workstation, and Area C moves 650mm so that each carrier 2 on the 5 workstations in area C moves forward one workstation.

[0069] Carrier 2 arrives at the first station in area C, and the positioning cylinder 56 drives the triangular positioning block to insert into the positioning profiling block of carrier 2, and the equipment starts the current 40s station operation.

[0070] The cylinder 56 on the fork mechanism 5 drives the cam 591 on the fork follower 59 to rotate out of the limit groove 92, so that the fork mechanism 5 is separated from the carrier 2. The servo motor 61 drives the fork mechanism 5 to move 650mm to the left. After the workstation operation is completed, the next carrier 2 conveying cycle begins. Each cycle time is 40s, and the carrier 2 is conveyed to the right lifting linear module 1 in turn, thereby completing the partitioned timing transfer process of the carrier 2 cycle.

[0071] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
