In summary, the first driving part 3 and the second driving part 4 are designed on the bracket 1 to drive the carrier 2 to intermittently move on the first guide rod 11 and the second guide rod 12, so as to facilitate the processing; the transfer part 5 is designed to transfer the workpiece P processed on the first guide rod 11 to the second guide rod 12 for further processing; the first guide rod 11 and the second guide rod 12 are respectively arranged on the upper side and the lower side of the bracket 1 to form a double-layer design, so that the three-dimensional space can be fully utilized, and the occupied area is reduced; the first guide rod 11 and the second guide rod 12 can limit the guide block 20 on the carrier 2, so that the carrier 2 can be prevented from deviating in the moving process, and the processing precision of the workpiece P is improved; in addition, the plurality of carriers 2 intermittently move for processing, so that the processing continuity of the workpiece P can be improved.

Referring to fig. 4-8 and 11-12, the carrier 2 includes a carrier plate 21 and a limiting component 22, the carrier plate 21 is provided with a storage slot 210, and the guide block 20 is mounted on the carrier plate 21; the position-limiting component 22 is mounted on the carrier 21 and can limit the workpiece P in the storage slot 210.

Specifically, the article placing groove 210 is used for placing the workpiece P, and the limiting component 22 is used for limiting the workpiece P, so that the workpiece P is completely fixed in the article placing groove 210; the design can avoid the workpiece P from shaking in the moving and machining process so as to improve the machining precision.

Referring to fig. 4-8 and fig. 11-12, further, the structure of the limiting assembly 22 is various, for easy understanding, the limiting assembly 22 of the present invention includes a pressing block 221 and an elastic member 222, a moving column 211 is vertically disposed on the support plate 21, and a supporting plate 212 is disposed on one end of the moving column 211 away from the support plate 21; the pressing block 221 is positioned above the object holding groove 210 and is connected with the moving column 211 in a sliding way, so that the pressing block 221 is far away from or attached to the carrier plate 21, and a processing groove 2210 corresponding to the object holding groove 210 is further arranged on the pressing block 221; the elastic member 222 is disposed on the pressing block 221, and two ends of the elastic member 222 respectively abut against the pressing block 221 and the abutting plate 212; when the pressing piece 221 is attached to the carrier plate 21, the elastic member 222 is in a normal state, and the pressing piece 221 abuts against the side edge of the workpiece P placed in the placement groove 210.

Specifically, in general, the pressing piece 221 abuts against the carrier plate 21, and the elastic piece 222 is in a normal state; when the workpiece P needs to be placed in the placing groove 210, the pressing block 221 is shifted upwards, so that the pressing block 221 is far away from the carrier plate 21, and in the process, the elastic member 222 stores energy and compresses; after the workpiece P is placed, the pressing block 221 is released, the elastic member 222 releases energy and recovers, the pressing block 221 is driven to move downwards to be attached to the support plate 21, and the pressing block 221 abuts against the edge of the limited workpiece P, so that the workpiece P can be limited in the storage groove 210; when the workpiece P needs to be taken out, the pressing block 221 is shifted to move upward, so that the pressing block 221 is far away from the carrier plate 21.

Specifically, when the carrier 2 moves onto the bearing block 54, the blocking column 23 blocks the second sensing part 9, and at this time, the second sensing part 9 sends a command to the second air cylinder 81 to control the extension of the telescopic shaft of the second air cylinder 81, so that the clamping column 82k is clamped into the clamping hole 21k;

when the bearing block 54 moves down, the stop pillar 23 is far away from the second sensing member 9, and the second sensing member 9 sends a command to the second cylinder 81 within a specific time to control the telescopic shaft of the second cylinder 81 to contract, so that the locking pillar 82k is separated from the locking hole 21k.

It should be noted that it takes a certain time for the carrier block 54 to move down from the first guide bar 11 to the second guide bar 12, and when the stop pillar 23 is far away from the second sensing member 9, the second sensing member 9 should send a command to the second cylinder 81 when the carrier block 54 reaches the second end of the second guide bar 12.

The second sensing member 9 may be an infrared sensor or an optical fiber sensor.

It should also be noted that while embodiments of the present application have been shown and described, it would be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the application.
