The first crossbeam 41a and the second crossbeam 41b are distributed in a horizontal direction. A clearance channel 42 is provided between the first crossbeam 41a and the second crossbeam 41b. Both the first lifting mechanism 31 and the second lifting mechanism 3 can pass through the clearance channel 42. The dual-position bracket has multiple positions along the translation direction.

[0021] The material pallet quick-change loading and unloading device described in this embodiment has a parking space for placing the pallets. The first crossbeam 41a and the second crossbeam 41b are used to support the two ends of the pallets respectively. The first lifting mechanism 31 lowers the full pallet to the parking space, and the second lifting mechanism 3 raises the full pallet on the parking space to the picking height and lowers the empty pallet to the parking space.

The lifting platforms are used to support the bottom of the material tray. The lifting platforms are set vertically opposite to the clearance channel 42, and the lifting platforms are smaller than the clearance channel 42 to ensure that the lifting platforms can pass vertically through the clearance channel 42 through the double-carriage support. The material tray can be lifted from the double-carriage support and placed on the double-carriage frame by the lifting platforms.

[0026] In one embodiment of the present invention, the lifting platform of the first lifting mechanism 31 is marked as the first lifting platform 12, the lifting platform of the second lifting mechanism 3 is marked as the second lifting platform 31, and the lifting platform of the third lifting mechanism 6 is marked as the third lifting platform.

[0027] Reference Figure 5 As shown, in one embodiment of the present invention, the second lifting platform 31 of the second lifting mechanism 3 is provided with a plurality of first positioning pins 33. The plurality of first positioning pins 33 are respectively aligned with the positioning holes of the material tray. During the process of the second lifting platform 31 rising to support the bottom of the material tray, the first positioning pins 33 are inserted into the positioning holes to position the material tray.

[0028] In one embodiment of the present invention, the second lifting platform 31 is arrayed with four first positioning pins 33.

[0029] Reference Figure 1 As shown, in one embodiment of this utility model, the linear transmission module includes a first linear transmission module 4a and a second linear transmission module 4b. The first linear transmission module 4a and the second linear transmission module 4b are used to drive the first crossbeam 41a and the second crossbeam 41b to move synchronously, ensuring that the dual-position bracket can avoid the first lifting mechanism 31, the second lifting mechanism 3 and the third lifting mechanism 6 during the translation process, and preventing interference.

[0030] Reference Figure 1 As shown, in one embodiment of the present invention, the transfer mechanism 4 further includes a transmission shaft 48 and a motor 47 that drives the transmission shaft 48 to rotate.

[0032] Reference Figure 1 and Figure 4As shown, in one embodiment of this utility model, a positioning mechanism 7 is further provided in the working area 9.

Specifically, the positioning mechanism 7 includes a horizontal baffle 71 and a plurality of positioning elements 73 provided at the bottom of the horizontal baffle 71. The plurality of positioning elements 73 are provided on opposite sides of the horizontal baffle 71. The horizontal baffle 71 is provided directly above the second lifting mechanism 3, and the horizontal baffle 71 is provided with a material picking port 72. The material picking port 72 is used for the robot arm to pass through the horizontal baffle 71 to grasp the parts on the tray. When the second lifting mechanism 3 raises the full material tray to a certain height, the two ends of the full material tray are blocked by the positioning elements 73 on both sides in the horizontal direction and cannot move laterally, ensuring that the full material tray does not shift.

[0033] Referring to Figure 4, in one embodiment of this utility model, the bottom of the horizontal baffle 71 is also connected to a plurality of support columns, which are used to stably support the horizontal baffle 71 on the working area 9.

[0035] Reference Figure 4 As shown, in one embodiment of this utility model, the positioning member 73 is configured as a plate. The plate shape is beneficial to increase its contact surface with the material tray and expand the guiding range. Furthermore, the guiding part is configured as an inclined surface with the lower end of the positioning member 73 bent.

[0036] Reference Figure 4 As shown, in one embodiment of the present invention, the bottom of the horizontal baffle 71 is also provided with a plurality of second positioning pins 75. The second positioning pins 75 are used to insert into the positioning holes of the tray to achieve precise positioning of the tray. The second positioning pins 75 are set higher than the positioning member 73, the purpose of which is to first use the positioning member 73 to guide the tray and ensure that the second positioning pins 75 are aligned with the positioning holes of the tray.

[0037] Reference Figure 1 As shown, in one embodiment of this utility model, a full material tray storage mechanism 8a is also provided in the full material tray storage area 2. The full material tray storage mechanism 8a is located directly above the first lifting mechanism 31. The full material tray storage mechanism 8a is used to stack and store multiple full material trays, which can speed up the feeding efficiency. The full material tray storage mechanism 8a unlocks the bottom full material tray with the help of a release mechanism, so that it can automatically fall onto the double-position bracket.

[0038] Reference Figure 3and Figure 5 As shown, in one embodiment of the present invention, the first lifting mechanism 31 further includes a first cylinder 11 for driving the first lifting platform 12 to rise and fall. The first lifting mechanism 31 is exactly the same as the third lifting mechanism 6, and will not be described again. The second lifting mechanism 3 further includes a second cylinder 32 for driving the second lifting platform 31 to rise and fall.

[0039] Reference Figure 1 As shown, in one embodiment of this utility model, the first lifting mechanism 31, the second lifting mechanism 3, and the third lifting mechanism 6 are all located between the first linear transmission module 4a and the second linear transmission module 4b, so that the lifting platform can vertically pass through the avoidance channel 42.

[0040] Reference Figure 7 As shown, in one embodiment of this utility model, the plurality of parking spaces include a first parking space 43 and a second parking space 44 distributed along the translation direction. The first parking space 43 and the second parking space 44 can each hold a material tray. When the first parking space 43 is located in the full material tray storage area 2, the second parking space 44 is located in the working area 9. Similarly, when the first parking space 43 is located in the working area 9, the second parking space 44 is located in the empty material tray storage area 5.

[0041] Reference Figure 6 As shown, in one embodiment of this utility model, positioning supports are provided on both the first parking space 43 and the second parking space 44. The positioning supports are used to support and position the material tray to prevent the material tray from shifting laterally and detaching from the double parking space bracket. Specifically, the positioning supports include a first positioning support 46a and a second positioning support 46b. The first positioning support 46a and the second positioning support 46b are respectively disposed on the first crossbeam 41a and the second crossbeam 41b, and the inner side of the first positioning support 46a and the second positioning support 46b are provided with positioning recesses 46a1. The positioning recesses 46a1 are matched with the material tray. When the material tray is placed on the first parking space 43 and the second parking space 44, one end of the material tray is located in the positioning recess 46a1 of the first positioning support 46a, and the other end of the material tray is located in the positioning recess 46a1 of the second positioning support 46b.

[0042] The working principle of the material tray quick switching loading and unloading device described in this utility model is as follows: During loading, the full pallet storage mechanism 8a places the bottom full pallet on the first lifting platform 12. Then, the first lifting platform 12 descends to place the full pallet on the first parking space 43. At the same time, the second lifting platform 31 descends to place the empty pallet on the second parking space 44. Subsequently, the double parking space support moves towards the empty pallet storage area 5 until the first parking space 43 is moved to the working area 9 and the second parking space 44 is moved to the empty pallet storage area 5. Then, the second lifting platform 31 lifts the full pallet of the first parking space 43 to the picking height. After the full pallet is positioned by the positioning mechanism 7, feeding begins. At the same time, the third lifting platform lifts the empty pallet on the second parking space 44 to the empty pallet storage mechanism 8b for stacking and storage. Finally, the first parking space 43 is moved back to the full pallet storage area 2 and the second parking space 44 is moved back to the working area 9, and this cycle repeats.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
