[0039] Reference Figures 1 to 3 According to the material transfer device of the embodiment of the present invention, the material transfer device includes a frame 10, a loading and unloading mechanism 20, a transfer mechanism 30 and a turnover mechanism 40. The loading and unloading mechanism 20 is arranged on the frame 10, and the loading and unloading mechanism 20 includes a tray 11 transfer component, and a tray 11 is arranged on the output end of the tray 11 transfer component, and the tray 11 is used to carry materials; the transfer mechanism 30 is arranged on the frame 10 and is located on one side of the loading and unloading mechanism 20, and the transfer mechanism 30 includes a clamping component 31, and the clamping component 31 is used to clamp and move materials; the turnover mechanism 40 can be detachably arranged on the frame 10, and the turnover mechanism 40 is connected to the loading and unloading mechanism 20. A plurality of trays 11 can be placed on the turnover mechanism 40, and the output end of the tray 11 transfer component is connected to the tray 11 to drive the tray 11 to move back and forth between the turnover mechanism 40 and the loading and unloading mechanism 20.

[0040] A pallet 11 carrying materials is placed in the turnover mechanism 40, and the turnover mechanism 40 is connected to the loading and unloading mechanism 20, and then the pallet 11 transfer component moves the pallet 11 from the turnover mechanism 40 to the loading and unloading mechanism 20, and the clamping component 31 of the transfer mechanism 30 can take out the materials from the pallet 11, and can also pick up materials at other stations and place them on the pallet 11 in the loading and unloading mechanism 20, so that loading and unloading can be performed at the same station. After picking up materials from the pallet 11 or loading materials, the pallet 11 can be transferred to another turnover mechanism 40 through the pallet 11 transfer component, and the pallet 11 or the pallet 11 carrying materials can be moved out of the station through another turnover mechanism 40.

[0041] Therefore, it can be understood that the material transfer device according to the embodiment of the present invention has at least the following beneficial effects: through the clamping assembly 31 of the transfer mechanism 30, the material in the tray 11 on the turnover mechanism 40 can be taken out or the material can be placed in the tray 11 in the turnover mechanism 40, and after the loading or unloading is completed, the new tray 11 can be replaced by the loading and unloading mechanism 20, so that the loading and unloading are both located at the same station, thereby greatly reducing the space occupied by the structure. At the same time, since the loading and unloading can be located at the same station, the working efficiency of loading and unloading can be greatly improved.

[0042] Further, in some embodiments of the present invention, referring to Figures 1 to 3 The loading and unloading mechanism 20 is arranged between the two turnover mechanisms 40. The loading and unloading mechanism 20 also includes a lifting assembly 22. The lifting assembly 22 is arranged on the frame 10 and located on one side of the transfer mechanism 30. The tray 11 transfer assembly is arranged on the lifting assembly 22. The lifting assembly 22 is used to drive the tray 11 transfer assembly to move up and down. In order to facilitate the tray 11 transfer assembly to take out the tray 11 from the turnover mechanism 40 or to facilitate the tray 11 transfer assembly to transfer the tray 11 to the turnover mechanism 40, the tray 11 transfer assembly can move up and down following the lifting assembly 22. When it is necessary to transfer the pallet 11 from the turnover mechanism 40 on one side to the loading and unloading mechanism 20, the pallet 11 transfer component moves to the bottom of the pallet 11 to transfer the pallet 11 to the loading and unloading mechanism 20, and then waits for the loading and unloading to be completed, and the pallet 11 transfer component can transfer the pallet 11 to the turnover mechanism 40 on the other side; then the lifting component 22 moves downward, driving the pallet 11 transfer component to move downward to the bottom of the next layer of pallets 11, and the pallet 11 transfer component moves to the turnover mechanism 40 on one side and moves to the bottom of the pallet 11, and then retreats to the loading and unloading mechanism 20, and the pallet 11 can be transferred to the loading and unloading station, and the material loading and unloading work is continued, thereby completing a cycle of material loading and unloading work.

[0043] Specifically, refer to Figure 2In some embodiments of the present invention, the lifting assembly 22 includes a lifting platform 221 and a first driving member 222. The lifting platform 221 is escalably disposed on the frame 10, and the tray 11 transfer assembly is disposed on the lifting platform 221; the first driving member 222 is disposed on the frame 10, and the output end of the first driving member 222 is connected to the lifting platform 221, and the first driving member 222 drives the lifting platform 221 to rise and fall on the frame 10. The first driving member 222 can be a driving motor, which can drive the lifting platform 221 to move up and down by driving the mechanism of the lead screw pair, thereby driving the tray 11 transfer assembly on the lifting platform 221 to move up and down, so that the tray 11 transfer assembly can shuttle back and forth between the trays 11 at different heights to drive the tray 11.

[0044] The lifting assembly 22 in the above embodiment is used to drive the tray 11 transfer assembly to move in the vertical direction, so it can be imagined that the lifting assembly 22 can also be other push structures (not shown in the figure), such as a gear rack structure, a cylinder or a hydraulic cylinder, etc. In this embodiment, no specific limitation is made, and it only needs to be able to drive the tray 11 transfer assembly to move up and down.

[0045] Furthermore, in some embodiments of the present invention, the lifting assembly 22 also includes a support platform 223, which is liftably disposed on the frame 10, and the lifting platform 221 is connected to the first driving member 222 through the support platform 223, and the support platform 223 is located at both ends of the lifting platform 221. A plurality of rollers 2231 are disposed on the inner side of the end edge of the support platform 223, and the plurality of rollers 2231 are horizontally arranged, and the sides of the rollers 2231 are used to support the bottom ends of both sides of the tray 11.

[0046] It is understandable that the two ends of the lifting platform 221 are provided with supporting platforms 223 arranged opposite to each other, and a sliding mechanism is arranged on the outer side of the supporting platform 223 to be connected to the frame 10, so that the supporting platform 223 can move on the frame 10 under the sliding of the sliding mechanism, and the lifting platform 221 sandwiched between the supporting platforms 223 can move up and down. On the inner side of the two supporting platforms 223, rollers 2231 arranged in sequence are arranged on the same horizontal plane, and the axes of the rollers 2231 are arranged vertically along the moving direction of the tray 11, so that the bottom surface of the tray 11 can be pressed against the side of the rollers 2231, and through the rotating rollers 2231 and the supporting effect of the rollers 2231, the tray 11 can be quickly transferred from the turnover mechanism 40 to the loading and unloading mechanism 20 and the supporting force of the tray 11 is provided by the supporting platform 223.

[0047] Specifically, refer to Figures 1 to 3In some embodiments of the present invention, the tray 11 transfer assembly includes a second driving member 211, a slide 212, and a pusher 213. The second driving member 211 is disposed on the lifting assembly 22; the slide 212 is slidably disposed on the lifting assembly 22, the output end of the second driving member 211 is connected to the slide 212, and the second driving member 211 is used to drive the slide 212 to slide back and forth between the two turnover mechanisms 40; the pusher 213 is movably disposed on the slide 212, and the pusher 213 can be close to or away from the thrust member 111 disposed at the bottom of the tray 11. The second driving member 211 drives the slide 212 to slide back and forth between the two turnover mechanisms 40. When the slide 212 slides into the turnover mechanism 40 on one side, the pusher 213 on the slide 212 can approach the thrust member 111 at the bottom of the tray 11 and abut against the thrust member 111. Then the second driving member 211 drives the slide 212 to move toward the other side of the turnover mechanism 40 and reset to the loading and unloading mechanism 20, so that the tray 11 is transferred to the working position of the loading and unloading mechanism 20 through the pusher 213. After the loading and unloading work is completed, the second driving member 211 can drive the slide 212 to continue to move toward the other side of the turnover mechanism 40, and finally transfer the tray 11 to the turnover mechanism 40.

[0048] It should be noted that the pushing member 213 on the slide 212 and the thrust member 111 at the bottom of the tray 11 can be in a complementary mechanism relationship. For example, if the pushing member 213 is a slot, the corresponding thrust member 111 is a block, and the thrust member 111 can be connected to the pushing member 213, so that the slide 212 can drive the tray 11 to move; the pushing member 213 can also be a connecting rod, and the corresponding thrust member 111 is a through hole, and the pushing member 213 can be penetrated on the thrust member 111, so that the slide 212 can drive the tray 11 to move. Of course, other thrust members 111 and corresponding pushing members 213 can also be provided, as long as they can achieve connection and drive the tray 11 to move, and no specific limitation is made in this embodiment.

[0049] It should also be noted that the pushing member 213 can be moved away from and approached to the thrust member 111 by a motor or a gear rack, so the present embodiment does not specifically limit the driving method of the pushing member 213.

[0050] Furthermore, in some embodiments of the present invention, two pushers 213 are provided on the slide 212, and the two pushers 213 are arranged at intervals along the moving direction of the tray 11, and the two pushers 213 can respectively abut or move away from the thrust member 111. The two pushers are respectively located at the two ends of the slide 212. When the slide 212 is close to one side of the turnover mechanism 40, the pusher 213 at the end of the slide 212 can be engaged with the tray 11 in the turnover mechanism 40, and the tray 11 can be removed from it without a longer slide 212; and when the slide 212 slides to the other side of the turnover mechanism 40, the pusher 213 at the other end can be used to push the tray 11 into the turnover mechanism 40, so that the tray 11 is placed in place.

[0051] Reference Figures 1 to 3 In some embodiments of the invention, the loading and unloading mechanism 20 further includes a positioning assembly 23, which is arranged on the lifting assembly 22 and located on one side of the lifting assembly 22. The positioning assembly 23 includes a movable first positioning block 231, and the first positioning block 231 can be away from or can abut against the second positioning block 112 arranged on the tray 11. It can be understood that the positioning assembly 23 can move up and down following the lifting assembly 22 under the drive of the first driving member 222. Specifically, the positioning assembly 23 can be installed on the supporting platform 223, and its first positioning block 231 can be close to the tray 11, which is conducive to the first positioning block 231 and the second positioning block 112 on the tray 11. Therefore, it can be imagined that when the tray 11 transfer assembly transfers the tray 11 to the supporting platform 223 above the lifting platform 221, the first positioning block 231 can be driven by the multi-driving member to be close to the second positioning block 112 on the tray 11, thereby realizing the snap-fitting, so as to achieve the purpose of positioning the tray 11.

[0052] However, it should be noted that both the first positioning block 231 and the second positioning block 112 are provided with guiding inclined surfaces, which can cooperate with each other and are more conducive to the clamping and positioning between the two.

[0053] Reference Figure 1 as well as Figure 3 In some embodiments of the present invention, the turnover mechanism 40 includes a bracket 41 and a plurality of support racks 42. The plurality of support racks 42 are arranged on the bracket 41. The support racks 42 are arranged in a vertical direction, and the tray 11 can be placed on the support racks 42. The support racks 42 are arranged on both sides of the bracket 41, so that both sides of the tray 11 can be carried on the top of the bracket 41. A plurality of support racks 42 are arranged in a vertical direction, so that a plurality of trays 11 can be carried.

[0054] Reference Figure 1In some embodiments of the present invention, the transfer mechanism 30 includes a mechanical arm 32, and the clamping assembly 31 is detachably arranged at the output end of the mechanical arm 32. The mechanical arm 32 may have multiple movable dimensions, so that the clamping assembly 31 at its output end can pick up or release materials at various positions. And through the detachable connection mode of the clamping assembly 31, different clamping assemblies 31 can be replaced, thereby satisfying more kinds of material loading and unloading work. Therefore, it can also be imagined that the material transfer device also includes a feeding mechanism 50, which can be movably arranged on the frame 10 and located on one side of the transfer mechanism 30. The feeding mechanism 50 is used to transport materials. The feeding mechanism 50 can be a material conveying mechanism or a material storage mechanism on other workstations, etc. The transfer mechanism 30 can be used to clamp the material on the feeding mechanism 50 and place it on the tray 11, and the material on the tray 11 can also be placed in the feeding mechanism 50.

[0055] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
