Each positioning device 21 includes a rotary base 211 and a plurality of positioning columns 212. The rotary base 211 is rotatably arranged on the frame 1 relative to the frame 1 around its own rotation axis, and the positioning columns 212 are connected to different positions of the rotary base 211.

[0045] In this embodiment, the frame 1 is the main body of the conveying device, is the carrier of all functions, has a suitable external shape size and sufficient structural strength, provides an installation basis for the positioning mechanism 20, and the bottom surface is installed with casters 7 for moving and transporting. The positioning mechanism 2 fixes the parts to be transported. Among them, the positioning column 212 is a component for positioning the parts. A plurality of positioning columns enclose a space imitating the shape of the parts, realizing the positioning of the parts stored in the conveying device. By adjusting the position of the positioning column 212 on the rotary base 211, the positioning of parts with different shapes and sizes can be realized, greatly improving the compatibility and flexibility of the conveying device. The rotary base 211 is set as a polygonal structure, preferably a quadrilateral, providing four working positions in four directions. The rotary base 211 can rotate around its own rotation axis on the frame 1 to realize multi-directional operation and multi-directional positioning.

[0046] Optionally, as shown in Figure 5 , the positioning column 212 can be optionally equipped with different numbers of long positioning columns 2121, short positioning columns (not shown in the figure) and special positioning columns 2122 according to requirements to realize flexible positioning. Specifically, the main feature of the special positioning column 2122 is that there are two legs at the part inserted into the rotary base 211, which can prevent the positioning column from rotating, and the structure at the upper end is used for positioning the parts and can be designed according to the parts to be transported.

[0047] Optionally, the positioning post 212 uses a metal mandrel with a plastic outer coating to protect the appearance of the transported parts from being scratched by the metal mandrel.

[0048] Preferably, the rotary base 211 is provided with array holes 2111; a locking plate 213 that rotates relative to the rotary base 211 is provided at the lower end of the rotary base 211. The lower end of the positioning post 212 passes through the array holes 2111 and is connected to the locking plate 213, and the locking plate 213 locks the positioning post 212. The array holes 2111 provide mounting holes for the positioning post 212 at different positions on the rotary base 211, and the positioning post 212 is locked by the locking plate 213.

[0049] Further, a number of stepped holes 2131 are arranged on the locking plate 213; a groove necking 2123 is provided at the lower end of the positioning post 212, and the groove necking 2123 passes through the array holes 2111 and is connected to the stepped holes 2131. The locking plate 213 is located below the rotary base 211 and can rotate relative to the rotary base 211. When the bottom of the positioning post 212 passes through the array holes 2111, the groove necking 2123 of the positioning post 212 will protrude from the rotary base 211 and penetrate into the large end of the stepped holes 2131 of the locking plate 213. Rotate the locking plate 213 so that the small end of the stepped holes 2131 is stuck on the groove necking 2123 to realize the locking of the positioning post 212 and prevent it from disengaging upward.

[0050] Optionally, another solution for the locking plate 213 to lock the positioning post 212: the locking plate 213 is arranged to be translatable relative to the rotary base 211. When the bottom of the positioning post 212 passes through the array holes 2111, the groove necking 2123 of the positioning post 212 will protrude from the rotary base 211 and penetrate into the large end of the stepped holes 2131 of the locking plate 213. At this time, translate the locking plate 213 so that the small end of the stepped holes 2131 is stuck on the groove necking 2123 to realize the locking of the positioning post 212.

[0051] Optionally, the stepped holes 2131 can be one or more of triangular holes, trapezoidal holes, and drop-shaped holes.

[0052] Preferably, the flexible positioning and conveying device of this embodiment further includes a base 4, a slewing bearing 5, and a transition ring 6; the base 4 is connected to the upper part of the frame 1, the slewing bearing 5 is fixed to the upper part of the base 4, the transition ring 6 is fixed to the upper part of the slewing bearing 5, and the locking plate 213 is rotatably connected to the upper part of the transition ring 6.

[0053] The base 4 is used to support the slewing bearing 5, and the slewing bearing 5 is a bearing used to support the stable rotation of the positioning device 21. The transition ring 6 provides a rotation space for the locking plate 213, and the locking plate 213 rotates on the circular shaft of the transition ring 6 to realize rotation relative to the rotary base 211.

[0054] Preferably, the conveying device further includes a hand insertion pin 214 which sequentially passes through the rotary base 211 and the locking plate 213 and is connected to the base 4. Openings corresponding in position are provided on the rotary base 211, the locking plate 213 and the base 4 for the hand insertion pin to pass through, and the positioning device 21 is locked and stopped from rotating through the hand insertion pin 214.

[0055] Preferably, at least one positioning device 21 in each group of positioning mechanisms 2 is slidably arranged in the first direction. Optionally, only one positioning device 21 can be slidably arranged in the first direction, or two or more positioning devices 21 can be slidably arranged in the first direction, or all the positioning components 21 can be slidably arranged in the first direction.

[0056] By operating at least one positioning device 21, the distance between this positioning device 21 and the adjacent positioning device 21 can be adjusted, so that each group of positioning mechanisms 2 can fix parts with different lengths, thereby further improving the versatility of the conveying device.

[0057] Furthermore, a slide rail 81 extending in the first direction is provided on the frame 1, and a slider 82 that slides on the slide rail 81 is provided at the lower end of the base 4 of the slidably arranged positioning device 21. In each slidably arranged positioning device 21, by operating the slider 82 to linearly slide relative to the slide rail 81 with low resistance, the base 4, the slewing support 5, the transition ring 6 and the positioning device 21 can be driven to slide, so as to facilitate the adjustment of the spacing.

[0058] Still further, a positioning hole plate 83 is provided between the frame 1 and the slide rail 81, and a number of positioning holes are provided on the positioning hole plate 83; a positioning pin 84 passes through the base 4 and is connected to the positioning hole. The base is locked at different positions.

[0059] Preferably, there are multiple groups of positioning mechanisms 2, and the multiple groups of positioning mechanisms 2 are arranged at intervals in a second direction intersecting with the first direction (such as Figure 1 the direction indicated by the arrow b in the figure). Optionally, there can be only one group of positioning mechanisms 2, or at least two groups. Preferably, there are multiple groups of positioning mechanisms 2, and the multiple groups of positioning mechanisms 2 are arranged at intervals in a second direction intersecting with the first direction. Multiple groups of positioning mechanisms 2 can position multiple parts simultaneously, improving the transportation efficiency of the transportation device. Optionally, the included angle between the first direction and the second direction can be 30°, 60°, 100°, etc. In this embodiment, the first direction and the second direction are perpendicular, and the first direction is the width direction of the frame 1, and the second direction is the length direction of the frame 1.

[0060] Preferably, the slewing base 211 is configured as a double layer. The double-layer slewing bases are connected together by connecting columns, and the same array of holes 2111 are formed in the upper and lower layers, which means that the depth of the array of holes 2111 is increased and the mating surface between the positioning posts 212 and the slewing base 211 is extended. The longer the mating surface, the higher the positioning accuracy. At the same time, the weight of the slewing base 211 is reduced, and the labor intensity of the workers is alleviated.

[0061] A positioning block 215 is provided at the upper end of the slewing base 211. The positioning block 215 serves an auxiliary positioning function and can be designed in different shapes according to different transported parts.

[0062] The working process of the flexible positioning and conveying device described in this embodiment is as follows: Place the parts to be transported on one or more slewing bases 211, adjust the distance between the fixing devices 21 through the sliders 82 to adapt to the size of the parts, insert the positioning pins 84 into the positioning holes on the positioning hole plate 83 to fix the positioning device 21; Select and match the positioning posts 212 and positioning blocks 215 that adapt to the size and shape of the parts, insert the positioning posts 212 into the array of holes 2111 and the stepped holes 2131 at appropriate positions in sequence, rotate the locking plate 213 to lock the positioning posts 212, and position the positioning blocks 215 at appropriate positions; The hand insertion pins 214 pass through the slewing base 211 and the locking plate 213 in sequence and are connected to the base 4 to lock and stop the rotation of the positioning device 21; Transport the parts through the casters.
