First, referring to fig. 1 to 3, an exemplary material loading and unloading all-in-one machine provided in this embodiment is described, where the material loading and unloading all-in-one machine is used for loading and unloading materials 13 in a turnover box 1 having a plurality of material layers, and the turnover box 1 is provided with a first opening 11 on one side wall and a second opening 12 on the other side wall of two opposite side walls for each material layer; the loading and unloading all-in-one includes: the device comprises a rack 2, a lifting platform 21 and a first pushing mechanism 22, wherein the lifting platform 21 is arranged to enable any material layer of the turnover box 1 placed on the lifting platform to reach a loading and unloading position through lifting, the first opening 11 of the material layer is opposite to a first push rod 221 of the first pushing mechanism 22 at the loading and unloading position, the first push rod 221 is arranged to be capable of performing telescopic movement in the lifting direction vertical to the lifting platform 21, and the first push rod 221 can extend into the first opening 11 and push out materials 13 in the material layer from a second opening 12; the connecting table 3 is provided with a first conveying rail 31 and a second pushing mechanism 32, the first conveying rail 31 is located on one side, back to the first push rod 221, of the lifting table 21, when the lifting table 21 lifts one material layer of the turnover box 1 to the loading and unloading position, the first conveying rail 31 is over against the bottom wall of the second opening 12 of the material layer, and the first conveying rail 31 can convey the material 13 on the first conveying rail in the direction away from and close to the lifting table 21; the second pushing mechanism 32 is configured to push the material 13 into the material layer from the second opening 12 by the second pushing rod 321 of the second pushing mechanism 32 when the first conveying rail 31 conveys the material 13 thereon to the second opening 12.

Illustratively, the work flow of the material handling all-in-one machine is described here, as shown in fig. 2 and fig. 3, after the turnover box 1 is placed on the lifting platform 21, the lifting platform 21 lifts the turnover box 1 to the first opening 11 of the first material layer on the upper portion of the turnover box to face the first push rod 221, the first push rod 221 pushes out the material 13 in the first material layer from the second opening 12 onto the first conveying rail 31, and with continued reference to fig. 1, the first conveying rail 31 conveys the material 13 to a preset position, and then the material 13 is removed manually or by a mechanical hand to be detected or processed. After that, the processed and detected qualified material 13 is placed at the set position of the first conveying rail 31, the first conveying rail 31 conveys the material 13 to the second opening 12 of the material layer, and the second push rod 321 pushes the material 13 into the material layer, with reference to fig. 3, the lifting table 21 drives the turnover box 1 to ascend by the height of one material layer again, and then the next cycle is started. It can be understood that if the corresponding material 13 is not detected to be qualified, the step of placing the material 13 on the first conveying rail 31 is not performed, the material layer is not subjected to the step of reloading the material layer with the qualified detection material, and the lifting table 21 directly drives the turnover box 1 to ascend by the height of one material layer again to enter the next cycle.

As still another preferred embodiment of the loading and unloading all-in-one machine provided in this embodiment, with continuing reference to fig. 1 and 2, the loading and unloading all-in-one machine further includes: and the second conveying track 4 is connected with one side of the first conveying track 31, which is opposite to the lifting platform 21, and can convey the materials 13 conveyed on the first conveying track 31 in a direction away from the lifting platform 21. In this way, the second conveying rail 4 is stopped when the material 13 conveyed by the first conveying rail 31 is conveyed to the set position, and then the material 13 is removed by a human or a robot for detection or processing. So, can take away material 13 or the preset position of placing sets up respectively on the delivery track of difference, can be convenient for take away or place the action of material 13 simultaneously to save the time of material 13 loading and unloading.

So circulate, until the last material layer of bottom in the turnover case 1 rises and finishes, can lift off the material 13 in each material layer from top to bottom in the turnover case 1 to and will process and finish and detect qualified material 13 and pack back to the week vanning, then put the next turnover case 1 that is equipped with the material 13 that treats processing or treats to detect on elevating platform 21 again. Therefore, the purpose of loading and unloading the material 13 by using one machine is realized, and the cost and the use space of loading and unloading equipment are further reduced.

It should be noted that the material 13 suitable for loading and unloading of the loading and unloading all-in-one machine provided in this embodiment may be a PCB (Printed Circuit Board) to be detected or processed, or may be other kinds of materials 13. As shown in fig. 1, the first conveying track 31 and the second conveying track 4 of the present embodiment may be double belt tracks, and the material 13 is clamped between the double belt tracks for conveying.

As still another preferred embodiment of the integrated material loading and unloading machine provided in this embodiment, with reference to fig. 1, the second pushing mechanism 32 further includes a slide rail 322 disposed below the first conveying rail 31, and a base of the second push rod 321 is slidably disposed on the slide rail 322.

Thus, when the first conveying rail 31 conveys the material 13 in the direction away from the lifting table 21, the second push rod 321 can be located at a position away from the lifting table 21, and when the first conveying rail 31 conveys the material 13 to the second opening 12 of the material layer, the second push rod 321 can slide along the slide rail 322 to a position close to the lifting table 21, and then the second push rod 321 can slide along the slide rail 322 to a position away from the lifting table 21 after pushing the material 13 at the second opening 12 to the material layer.

Thus, the purpose of conveying the turnover box 1 filled with the materials 13 to be detected or processed to the lifting platform 21 can be achieved. In addition, the loading and unloading all-in-one machine can further comprise an upper turnover track 52 which is positioned on the same side of the first pushing mechanism 22 of the lifting platform 21 and is arranged at the highest position of the lifting platform 21 and used for conveying the turnover box 1 on the lifting platform 21 to a position far away from the lifting platform 21, so that the purpose of conveying the turnover box 1 filled with the detected or processed materials 13 can be achieved.

As another preferred embodiment of the loading and unloading all-in-one machine provided in this embodiment, the loading and unloading all-in-one machine may further include: and the first material sensor is used for detecting the position of the material 13 on the first conveying track 31 or detecting the material 13 at a preset position on the first conveying track 31. Thus, the position information of the material 13 detected by the first material sensor can confirm that the material 13 is placed at the preset position of the first conveying rail 31, and then the first conveying rail 31 is controlled to convey the material 13 toward the lifting table 21.

Further, this loading and unloading all-in-one can also include: and the second material sensor is used for detecting the position of the material 13 on the second conveying track 4 or detecting the material 13 at a preset position on the second conveying track 4.
