The frame 300 is substantially a rectangular parallelepiped, and the length direction of the frame 300 extends along the X-axis direction, the width direction extends along the Y-axis direction, and the height direction extends along the Z-axis direction. As shown in fig. 3, the top of the frame 300 includes a first side 311, a second side 312, a third side 313 and a fourth side 314, and as shown in fig. 4, the calibration assemblies 400 are provided in at least two sets, for example, the calibration assemblies 400 may be provided on the first side 311 and the second side 312, respectively.

In one embodiment, as shown in fig. 4, the workpiece calibration system further includes a limit switch 600, the limit switch 600 is used to stop the movement of the table 500 in one direction, for example, the table 500 moves in a first direction, and after the workpiece on the table 500 impacts the calibration assembly 400, the table 500 continues to move in the first direction until the limit switch 600 is triggered and the table 500 stops moving in the first direction. If the limit switch 600 is activated and the workpiece on the table 500 still does not strike the calibration assembly 400, the workpiece can be manually pushed to strike the calibration assembly 400.

In one embodiment, the limit switch 600 is disposed on the frame 300, and the limit switch 600 is in signal connection with the driving assembly 100.

In one embodiment, as shown in fig. 6, the first guide member 110 extends along the X-axis direction, the second guide member 140 extends along the Y-axis direction, and the first guide member 110 and the second guide member 140 can be installed in the same plane, that is, the first guide member 110 and the second guide member 140 do not need to be distributed in different planes along the Z-axis direction, so that the Z-direction height of the driving assembly 100 is reduced, and the motion stability is improved.

In one embodiment, as shown in fig. 7, the first slider 120 includes a first arm 123 and a second arm 124 perpendicular to each other, the first arm 123 of the first slider 120 is provided with a slider 125 slidably connected to the first guide 110, and the second arm 124 of the first slider 120 is provided with a second guide 140.

In one embodiment, when the moving portion 102 is a suction cup, in order to ensure that the suction cup rotates unintentionally during movement and improve the firmness of suction, the firmness of installation of the suction cup needs to be ensured. The second driving member 160 includes a second moving end 162 and a second fixed end 161, and the second moving end 162 can slide relative to the second fixed end 161 along the second direction. The second sliding member 150 is fixed with a connecting seat 153, the second moving end 162 is fixed on the connecting seat 153, and the moving part 102 is fixed on the second sliding member 150. The fixed connection in this embodiment may be performed by bolts. Similarly, the second arm 124 may also be provided with a connecting seat 153, and the first moving end 132 is fixed on the connecting seat 153 of the second arm 124.

In one embodiment, as shown in FIG. 5, the workpiece correction system further comprises a limit switch 600, the limit switch 600 may be disposed on the correction assembly 400, and the limit switch 600 is in signal communication with the drive assembly 100. In other embodiments, the limit switch 600 may be disposed on the rack. The limit switch 600 is used to stop the movement of the workpiece in one direction. For example, the suction cup sucks the workpiece to move along a first direction, the workpiece impacts the calibration assembly 400, then the limit switch 600 on the calibration assembly 400 is triggered, and the driving assembly 100 receives a signal of the limit switch 600 and stops driving the workpiece to move along the direction. In one embodiment, when the workpiece moves in the first direction and strikes one of the limit switches 600, the driving assembly 100 receives the trigger signal from the limit switch 600, stops driving the workpiece to move in the first direction, and starts moving the workpiece in the second direction, and when the workpiece again strikes another correction assembly 400 and strikes the limit switch 600 thereon, the driving assembly 100 receives the trigger signal and stops driving the workpiece to move. In other embodiments, at least two limit switches 600 are provided, and the limit switches 600 may be provided on the rack 300.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
