[0024] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0025] Please refer to Figures 1 to 5 The specific embodiment of the utility model relates to a multi-station material 5 transfer mechanism, which is used for transfer between a conveyor line and a CNC machine tool. The transfer mechanism includes a frame 1, n material stopping stations 2 arranged on the frame 1 in sequence along the X direction, the X direction being the transfer direction, the frame 1 is provided with a moving part 3 movable along the X direction, the moving part 3 is connected with a lifting part 4, each material stopping station 2 is provided with a first sensor 11 for sensing the material 5, and the frame 1 is provided with a second sensor 12 for sensing the position of the moving part 3;

[0026] The method for transferring material 5 by multiplexing includes the following steps:

[0027] S1: Control the lifting member 4 to descend and separate from the material 5; sequentially obtain the sensing signals of the first sensors 11 in the reverse direction of the X direction; when the sensing signal of one of the first sensors 11 is obtained for the first time that there is no material 5, the position of the material stopping station 2 is recorded as the first position; continue to sequentially obtain the sensing signals of the first sensors 11 in the reverse direction of the X direction; when the sensing signal of one of the first sensors 11 is obtained for the first time that there is material 5, the position of the material stopping station 2 is recorded as the second position;

[0028] S2: obtaining the current position of the moving member 3 through the second sensor 12, controlling the moving member 3 to move to the second position, controlling the lifting member 4 to rise, and lifting the material 5 parked at the second position;

[0029] S3: Control the moving member 3 to move to the first position;

[0030] Repeat the above steps S1-S3.

[0031] The above steps are explained below in conjunction with a specific embodiment: take n as 5 as an example, that is, the first stop station 2, the second stop station 2, the third stop station 2, the fourth stop station 2 and the fifth stop station 2 are arranged in sequence on the frame 1 along the X direction, the first stop station 2 is a loading station, and the fifth stop station 2 is an unloading station. In a simulated case, there are materials 5 on the first stop station 2, the fourth stop station 2 and the fifth stop station 2, while there are no materials 5 on the second stop station 2 and the third stop station 2. At this time, it is first obtained that there is no material 5 on the third stop station 2, and then it is obtained that there is material 5 on the first stop station 2, and then it is obtained that there is material 5 on the first stop station 2. At this time, the position of the moving part 3 is obtained by the second sensor 12, and the moving part 3 is controlled to move to the first stop station 2, and the material 5 on the first stop station 2 is lifted up and transferred to the third stop station 2.

[0032] The above implementation mode is suitable for application in the scenario of combining with the Chinese patent with publication number CN114455277A, which discloses a device and method for delivering materials 5 of different lengths from multiple stations to the finished product area, that is, it is applied to the temporary stop and transfer of materials 5 between each processing station and the conveyor line. For example, after the CNC machine tool at one of the processing stations processes a material 5, it is first transferred to the above-mentioned first material stop station 2 by an industrial robot, and then through the above-mentioned method of the utility model, the moving part 3 is used to transfer the material 5 to a position close to the fifth material stop station 2 in turn. When the material 5 is transferred to the fifth material stop station 2, the corresponding judgment of the Chinese patent with publication number CN114455277A, which discloses a device and method for delivering materials 5 of different lengths from multiple stations to the finished product area, will be performed. When it is judged that there is currently a vacant position on the conveyor line, the material 5 at the fifth material stop station 2 is transferred to the conveyor line by the industrial robot.

[0033] As a preferred embodiment, the frame 1 is provided with a rack 13 arranged along the X direction, the moving member 3 is provided with a driving motor, the driving motor is transmission-connected with a gear 31, and the gear 31 is meshed with the rack 13;

[0034] In the transport method, in S2: controlling the moving member 3 to move to the second position specifically controls the driving motor to drive the gear 31 to rotate, and the moving member 3 moves to the second position through the meshing of the gear 31 and the rack 13;

[0035] In S3 , controlling the moving member 3 to move to the first position specifically involves controlling the driving motor to drive the gear 31 to rotate, and the moving member 3 is moved to the first position through the meshing of the gear 31 and the rack 13 .

[0036] As a preferred implementation, the frame 1 is provided with a limiting shaft 14 arranged along the X direction, and the moving member 3 is provided with a sleeve that is slidably matched with the limiting shaft 14 .

[0037] As a preferred embodiment, a material stopping platform is symmetrically arranged on both sides of the limit shaft 14, and a first arc-shaped limit groove 21 is respectively provided on the material stopping platform for the position of each material stopping station 2, and the first sensor 11 is a first proximity switch, and the first proximity switch is arranged in the first arc-shaped limit groove 21.

[0038] In the above implementation, since the material 5 is a cylindrical shaft-like part, during the transfer of the material 5, the material 5 can be limited by the first arc-shaped limit groove 21, and the first proximity switch can be used to identify whether there is material 5 parked at the current material stop station 2.

[0039] As a preferred embodiment, the second sensor 12 is a second proximity switch respectively arranged at each material stopping station 2, and the moving member 3 is provided with a stopper 32 for proximity sensing with the second proximity switch.

[0040] In the above implementation, since the moving part 3 is accurately parked at the corresponding material stopping station 2 after the last transfer, the current position information of the moving part 3 can be obtained through the signal that the second proximity switch at the position of the corresponding material stopping station 2 is blocked by the block 32, so that the next movement can be performed according to the steps.

[0041] As a preferred embodiment, the jacking member 4 includes a jacking cylinder 41 and a supporting seat 42, the cylinder body of the jacking cylinder 41 is connected to the moving member 3, the supporting seat 42 is connected to the upper end of the piston rod of the jacking cylinder 41, and the jacking seat is provided with a second arc-shaped limiting groove 421.

[0042] In the above embodiment, when transferring material 5, the material supporting seat 42 is first controlled to move downward, so as to avoid interference between the moving part 3 and the material 5 on each material stopping station 2 when moving. When moving to the target station where the material 5 needs to be transferred, the lifting cylinder 41 is controlled to lift up, so that the second arc-shaped limit groove 421 of the material supporting seat 42 limits and supports the material 5 on the material stopping station 2, so that the material 5 is separated from the first arc-shaped limit groove 21 on the material stopping station 2, and then the moving part 3 is controlled to move, so that the transfer of material 5 between the material stopping stations 2 can be realized.
