[0019] In the specific implementation process, the servo motor 32 is started, and under the assistance of the synchronous assembly 33, the main shaft 31 is driven to rotate, thereby driving the two groups of Y-axis cams 34 on the outer wall of the main shaft 31 to rotate, when the Y-axis cam 34 rotates, it drives the first connecting arm 352 in contact with it to move up and down, and then under the assistance of the first connecting rod 353 and the first connecting seat 351, the transfer frame 1 is driven to move up and down, so that the clamp installed on the transfer frame 1 can clamp the material on the material table.

[0020] Embodiment 2 Based on embodiment 1, this embodiment further comprises: referring to the accompanying Figures 4-7The X-axis cam 36 is fixedly arranged on the outer wall of the main shaft 31 and is located between the two groups of Y-axis cams 34, and the second connecting assembly 37 for left and right movement of the transfer frame 1 is arranged between the X-axis cam 36 and the transfer frame 1, the second connecting assembly 37 comprises a second connecting arm 371 abutting against the outer wall of the X-axis cam 36, an L-shaped connecting arm 372 movably hinged at one end of the second connecting arm 371, a support rod 374 movably hinged at the middle part of the L-shaped connecting arm 372, and a support 373 for supporting the support rod 374, and the end of the L-shaped connecting arm 372 away from the second connecting arm 371 is rotatably connected to one side of the transfer frame 1, and the end of the second connecting arm 371 away from the L-shaped connecting arm 372 is movably hinged with a mounting seat 375 for supporting the second connecting arm 371, and one end of the second connecting arm 371 and the L-shaped connecting arm 372 is provided with an auxiliary frame 376.

[0021] In the specific implementation process, the servo motor 32 is started to drive the main shaft 31 and the X-axis cam 36 fixedly connected to the outer wall of the main shaft 31 to rotate under the assistance of the synchronous assembly 33, at this time, the X-axis cam 36 drives the second connecting arm 371 in contact with it to move up and down, the second connecting arm 371 drives the L-shaped connecting arm 372 connected with it to deflect up and down around the support rod 374, and then drives the transfer frame 1 controlled by the L-shaped connecting arm 372 to move left and right, so as to realize the progressive reciprocating movement of the material at the transfer frame 1 and complete the transfer of the material.

[0022] Specifically, the working principle and operation method of the present application are as follows: Before transfer, the transfer frame 1 and the plurality of clamps installed on the transfer frame 1 are at the highest position in the up and down movement path, at this time, the clamps at the transfer frame 1 are not in contact with the material on the material table, the clamps on the transfer frame 1 correspond to each group of clamping positions on the material table one by one, for example, the first clamp on the transfer frame 1 corresponds to the first clamp station on the material table, the second clamp on the transfer frame 1 corresponds to the second clamp station on the material table, and so on.

[0023] When the transport is in progress, the servo motor 32 is started to drive the main shaft 31 to rotate with the aid of the synchronous assembly 33, and then drive the two groups of Y-axis cam 34 and X-axis cam 36 on the outer wall of the main shaft 31 to rotate simultaneously. Since the X-axis cam 36 is not the same size as the two groups of Y-axis cam 34, when the two groups of Y-axis cam 34 rotate, the distance between the outer wall of the Y-axis cam 34 and the contact position of the first connecting arm 352 changes, that is, the diameter between the center of the Y-axis cam 34 and the contact position of the first connecting arm 352 changes, so that the first connecting arm 352 can rotate around the support as the axis to drive the transport frame 1 to move downward with the aid of the first connecting seat 351 and the first connecting rod 353, until the clamp provided on the transport frame 1 can clamp the material on the material table clamping position, and then the transport frame 1 with the clamped material is driven to move upward with the aid of the Y-axis cam 34 and the first connecting assembly 35, so that the transport frame 1 returns to the initial position; At the same time, after the Y-axis cam 34 and the first connecting assembly 35 assist the transport frame 1 to move up and down to clamp and take the material, the outer wall of the X-axis cam 36 controlled by the main shaft 31 changes in diameter and rotates to the position where it contacts the second connecting arm 371, so that the one end of the second connecting arm 371 rotates up and down around the mounting seat 375 as the axis, and then drives the L-shaped connecting arm 372 hinged to the second connecting arm 371 to rotate up and down around the support rod 374 as the axis, so as to drive the transport frame 1 connected to one end of the L-shaped connecting arm 372 to move in the left and right direction to the upward material direction, for example, the No. 1 clamp on the transport frame 1 clamps the material at its position to the No. 2 clamp station on the material table in the left and right direction, and the No. 2 clamp on the transport frame 1 clamps the material at its position to the No. 3 clamp station on the material table corresponding to the No. 2 clamp station in the left and right direction, and so on, so that the material can be transferred on different material tables, so that the material can be processed in sequence on different material tables, and then the transport frame 1 with the changed left and right position is driven to move downward with the aid of the Y-axis cam 34 and the first connecting assembly 35, so that the material is transported to different positions; After the transport, the transport frame 1 moves upward to the initial position with the aid of the Y-axis cam 34 and the first connecting assembly 35, and at this time, the transport frame 1 is driven to reset in the left and right direction with the aid of the X-axis cam 36 and the second connecting assembly 37, for example, the No. 1 clamp on the transport frame 1 resets from the position corresponding to the No. 2 clamp station on the material table to the position corresponding to the No. 1 clamp station on the material table, thereby realizing progressive transport of the material.

[0024] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
