In this embodiment, the workpiece 10 is generally rectangular in structure, and optionally, the workpiece 10 may be circular or other irregular shapes.

[0086] The carrier plate 20 is provided with a through hole 21 and mounting portions 22 provided on both sides of the through hole 21 in the first direction X.

The first direction X, the second direction Y and the third direction Z are perpendicular to each other, so as to reduce the positioning mechanism 31 and the supporting mechanism 40 from being lower or higher than the first surface 221, which may cause the carrying workpiece 10 (see Figure 1 ) Risk of instability in the edge part.

[0089] Please continue reading Figure 2 and Figure 3In some embodiments, each positioning mechanism 31 includes a positioning plate 311 and two first fasteners 312, and the positioning plate 311 is connected between the two mounting portions 22. The first mounting grooves 3111 are provided at both ends of the positioning plate 311, and the first mounting grooves 3111 have a first bottom wall 3111A and a first side wall 3111B. The mounting portion 22 is further provided with a supporting surface 223 connected to the first surface 221 and the second surface 222, and the supporting surface 223 is configured to support the first side wall 3111B, and the first bottom wall 3111A is configured to support the second surface 222.

The first fastener 312 is configured to pass through the first fastening hole 224 and the second fastening hole 3111C to fasten the positioning plate 311 to the mounting portion 22, thereby improving the connection tightness and stability between the positioning plate 311 and the mounting portion 22.

[0090] Please continue reading Figure 2 and Figure 3 In some embodiments, the mounting portion 22 is further provided with a positioning hole 225 spaced apart from the first fastening hole 224, and the first bottom wall 3111A is provided with a protrusion 3111D, which is configured to extend into the positioning hole 225. The protrusion 3111D extends into the positioning hole 225 to improve the accuracy of the positioning plate 311 being installed on the mounting portion 22.

[0091] Please continue reading Figure 2 and Figure 3 In some embodiments, each positioning mechanism 31 further includes a positioning member 313, which is telescopically connected to the positioning plate 311 and is used to position the workpiece 10 (see Figure 1 ), improving the stability of the workpiece 10 when it is located on the positioning mechanism 31.

The screw portion 3131 is provided in the mounting hole 3112 and is partially exposed outside the mounting hole 3112. The screw portion 3131 is provided with a receiving cavity 3131A and a guide hole 3131B connected to the receiving cavity 3131A. The guide hole 3131B is provided at one end of the screw portion 3131 close to the first surface 221. One end of the positioning portion 3132 is slidably limited and connected to the receiving cavity 3131A, and the other end extends out of the guide hole 3131B to position the workpiece 10 (see FIG. 1 ). Figure 1The stopper 3134 is disposed in the accommodating cavity 3131A, and the elastic portion 3133 elastically abuts between the positioning portion 3132 and the stopper 3134. When the workpiece 10 is placed on the positioning plate 311, the elastic portion 3133 reacts on the positioning portion 3132 to abut the positioning portion 3132 for positioning the workpiece 10, thereby improving the stability of the positioning member 313 when positioning the workpiece 10.

The projection of the guide hole 3131B in the third direction Z is located within the projection range of the accommodating cavity 3131A in the third direction Z. Under the action of the elastic portion 3133, the guide block 3132A drives the positioning pin 3132B to position the workpiece 10. The guide block 3132A located in the accommodating cavity 3131A reduces the risk of the positioning pin 3132B being separated from the screw portion 3131 during the process of positioning the workpiece 10.

[0094] Please also read Figure 3 , Figure 4 and Figure 5 In some embodiments, the positioning member 313 also includes a fastening portion 3135, which is disposed on the side of the positioning plate 311 away from the second surface 222, and the fastening portion 3135 is connected to the portion of the screw portion 3131 extending out of the mounting hole 3112, thereby reducing the risk of the screw portion 3131 detaching from the positioning plate 311.

[0095] Please refer again Figure 2 and Figure 3 In some embodiments, the support mechanism 40 includes a support member 41 and a second fastener 42, and the support member 41 is connected to the second surface 222. The mounting portion 22 is further provided with a sliding hole 226 that penetrates the first surface 221 and the second surface 222, and the sliding hole 226 and the first fastening hole 224 are arranged along the second direction Y.

The second bottom wall 4111 is provided with a connecting hole 4113, and the second fastener 42 passes through the sliding hole 226 and the connecting hole 4113 in sequence to connect the support member 41, thereby improving the connection tightness and stability between the support member 41 and the mounting portion 22.

[0098] In this embodiment, the carrying device 100 includes two supporting mechanisms 40, which are arranged in parallel between two positioning mechanisms 31 to carry the workpiece 10. It can be understood that in order to adapt to workpieces 10 of different sizes, the number of supporting members 41 can be increased or decreased to improve the versatility of the carrying device 100. When carrying workpieces 10 of different sizes or models, different models of positioning mechanisms 31 and supporting mechanisms 40 can be replaced.

[0099] Please also read Figure 1 and Figure 3 In some embodiments, the supporting device 100 further includes a plurality of support columns 50, which are arranged at intervals on one side of the supporting plate 20 close to the second surface 222. The support columns 50 increase the height of the supporting plate 20 and reduce the risk of the supporting plate 20 being placed unsteadily on a plane due to the protruding positioning mechanism 31 and the supporting mechanism 40 on the second surface 222.
