[0037] Example 1

[0038] like Figure 1 、 Figure 2 、 Figure 3 As shown, this embodiment discloses a material transfer device, including a horizontal moving mechanism 1, a lifting mechanism 7, a lifting base 5, a sliding member 13, and a clamping mechanism 14, wherein:

[0039] The lifting base 5 is arranged in the sealed box chamber 8 and is connected to the lifting mechanism 7 outside the sealed box chamber. The lifting mechanism 7 is used to drive the lifting base 5 to perform lifting movement in the sealed box chamber 8;

[0040] The sliding member 13 is provided on the lifting base 5 and is connected to the horizontal moving mechanism 1 outside the sealed chamber 8. The horizontal moving mechanism 1 is used to drive the sliding member 13 to perform horizontal movement on the lifting base 5;

[0041] The clamping mechanism 14 is provided on the sliding member 13 and is used for clamping materials.

[0042] During operation, the clamping mechanism 14 is driven to move to the material through the cooperation of the horizontal moving mechanism 1 and the lifting mechanism 7, and then the material is clamped by the clamping mechanism 14. Then, the clamping mechanism 14 is driven to move to the target position to be transferred through the cooperation of the horizontal moving mechanism 1 and the lifting mechanism 7, and the material is put down, thereby completing the transfer of the material between different positions.

[0043] In some embodiments, as Figure 1 As shown, the lifting mechanism 7 includes a lifting drive 6 and a first lifting transmission member 31. The lifting drive 6 is arranged outside the sealed box chamber 8. The first lifting transmission member 31 is passed through the sealed box chamber 8. The two ends of the first lifting transmission member 31 are respectively connected to the lifting base 5 and the lifting drive 6. The lifting drive 6 drives the lifting base 5 to rise and fall by driving the first lifting transmission member 31.

[0044] Specifically, the lifting drive 6 is preferably provided at the top of the sealed chamber 8, and the first lifting transmission member 31 passes through the top of the sealed chamber 8. The lifting drive 6 can be a motor, a reducer, etc. The first lifting transmission member 31 can be a reducer, etc.

[0045] In some embodiments, as Figure 1 As shown, the lifting mechanism 7 also includes a long-distance transmission member 4 and a second lifting transmission member 32. The second lifting transmission member 32 is also passed through the sealed box chamber 8. One end of the second lifting transmission member 32 is connected to the lifting drive 6 through the long-distance transmission member 4, and the other end is also connected to the lifting base 5. The lifting drive 6 drives the first lifting transmission member 31 and the second lifting transmission member 32 to achieve synchronous lifting, thereby driving the lifting base 5 to lift.

[0046] Specifically, if Figure 3 As shown, the second lifting transmission member 32 is disposed transversely. The second lifting transmission member 32 is disposed opposite the first lifting transmission member 31, and is located at different ends of the sealed chamber 8. The lifting drive 6 is preferably located at the same end as the first lifting transmission member 31. The bottom end of the first lifting transmission member 31 is connected to one end of the lifting base 5, and the bottom end of the second lifting transmission member 32 is connected to the other end of the lifting base 5. The second lifting transmission member 32 has the same or similar structure as the first lifting transmission member 31, and will not be described in detail here.

[0047] In some embodiments, as Figure 2 As shown, the lifting mechanism 7 also includes a first dynamic sealing penetration member 10, and the first lifting transmission member 31 and the second lifting transmission member 32 are each movably provided on the sealed box chamber 8 through the first dynamic sealing penetration member 10, that is, the power of the lifting drive 7 is introduced into the sealed box chamber 8 through the first dynamic sealing penetration member 10.

[0048] In some embodiments, as Figure 2 、 Figure 3 As shown, the lifting mechanism 7 also includes a lifting guide 11, which is connected to the sealed box chamber 8. The first lifting transmission member 31 and the second lifting transmission member 32 are both connected to the lifting base 5 through the lifting guide 11 to ensure that the lifting base can be lifted stably.

[0049] Specifically, the lifting guide member mainly includes a sliding shaft seat, a guide shaft and other components. The guide shaft is fixed on the sealed box chamber through the sliding shaft seat. The first lifting transmission member 31 and the second lifting transmission member 32 both pass through the guide shaft in the lifting guide member 11.

[0050] In some embodiments, as Figure 1 As shown, the horizontal moving mechanism 1 includes a horizontal moving drive 2 and a horizontal moving transmission member 12. The horizontal moving drive 2 is arranged outside the sealed box chamber 8, and the horizontal moving transmission member 12 is passed through the sealed box chamber 8. The two ends of the horizontal moving transmission member 12 are respectively connected to the horizontal moving drive 2 and the sliding member 13. The horizontal moving drive 2 drives the horizontal moving transmission member 12 to drive the sliding member 13 to perform horizontal movement on the lifting base 5.

[0051] Specifically, the horizontal motion drive 2 is also preferably located at the top of the sealed chamber 8 and is preferably positioned opposite the lifting drive 6, at different ends of the top of the sealed chamber 8. The horizontal motion transmission member 12 passes through the top of the sealed chamber 8 and is located at the same end as the second lifting drive member 32, but at a different end from the first lifting drive member 31. The horizontal motion drive 2 can be a motor reducer or similar mechanism. The horizontal motion transmission member 12 can be a belt conveyor or similar mechanism.

[0052] In some embodiments, the horizontal moving mechanism 1 also includes a dynamic second dynamic sealing penetration component, and the horizontal moving transmission component 12 is movably installed on the sealed chamber 8 through the second dynamic sealing penetration component, that is, the power of the horizontal moving drive 2 is introduced into the sealed chamber 8 through the second dynamic sealing penetration component.

[0053] In some embodiments, as Figure 2 As shown, a horizontal motion guide is provided on the lifting base 5, and a sliding member 13 is provided on the horizontal motion guide.

[0054] Specifically, the horizontal motion guide can be a guide rail arranged on the lower surface of the lifting base 5, and a groove adapted to the guide rail is provided on the upper surface of the sliding member 13. The clamping mechanism 14 is provided on the lower surface of the sliding member 13. The sliding member 13 slides on the guide rail through the groove, thereby realizing horizontal movement, and then driving the clamping mechanism 14 to move in the horizontal direction.

[0055] In some embodiments, as Figure 4 As shown, the device further includes a horizontal movement adjustment mechanism 9, which is disposed on the lifting base 5 and is used to adjust the lifting base to a horizontal and tensioned state. Specifically, the horizontal movement adjustment mechanism 9 can be similar to a tensioning device that can be adjusted up and down, forward and backward, such as a movable adjustment block, and achieves its function by adjusting a drive wheel at one end of the horizontal movement transmission member 12.

[0056] In some embodiments, the device further comprises an automatic control mechanism (not shown in the figure), which comprises a first detector, a second detector and a controller.

[0057] Specifically, the first detector is electrically connected to the controller, and is used to detect the horizontal position of the clamping mechanism 14 and transmit the detected horizontal position information to the controller.

[0058] The second detector is electrically connected to the controller, and is used to detect the position height of the clamping mechanism 14 and transmit the detected position height information to the controller.

[0059] The controller is electrically connected to the horizontal moving drive 2, the lifting drive 2, and the clamping mechanism respectively. The controller is preset with initial position information set according to the position of the material. The controller is used to receive the horizontal position information transmitted by the first detector, and compare it with the initial position information to determine whether the clamping mechanism 14 moves horizontally to above the position of the material. When it is confirmed that the horizontal movement of the clamping mechanism 14 reaches above the position of the material, the horizontal moving drive 2 is controlled to be closed, and the lifting drive 6 is controlled to start to lower the clamping mechanism 14 to a height that is convenient for clamping the material. The controller is also used to receive the position height information transmitted by the second detector, and compare it with the initial position information to determine whether the clamping mechanism 14 is lowered to a height that is convenient for clamping the material. When it is confirmed that the position height of the clamping mechanism 14 reaches a height that is convenient for clamping the material, the lifting drive 6 is controlled to be closed, and the clamping mechanism 14 is controlled to clamp the material. Moreover, after the clamping mechanism clamps the material, the lifting drive is controlled to start again to raise the clamping mechanism and the material clamped therein. The specific rising position height can be pre-set in the controller according to demand, for example, rising back to the clamping height. The position height of the mechanism 14 before being lowered, when the clamping mechanism rises to the pre-set position height, the lifting drive 6 is controlled to be closed again, and the horizontal movement drive 2 is controlled to start again to move the clamping mechanism and the clamped material to the target position to which the material is to be transferred. The controller is also preset with target position information set according to the target position to which the material is to be transferred. The controller is also used to compare the horizontal position information transmitted by the received first detector with the target position information to determine whether the clamping mechanism 14 has moved horizontally to above the target position. When it is confirmed that the clamping mechanism 14 has moved horizontally to above the target position, the horizontal movement drive 2 is controlled to be closed again, and the lifting drive 6 is controlled again to start to lower the clamping mechanism 14 to a height that is convenient for placing the material to the target position. The controller is also used to compare the position height information transmitted by the received second detector with the target position information to determine whether the clamping mechanism 14 has been lowered to the height for placing the material to the target position. When it is confirmed that the position height of the clamping mechanism 14 has reached the height for placing the material to the target position, the lifting drive 6 is controlled to be closed again, and the clamping mechanism is controlled to release the material to complete the material transfer. The controller can also be used to control the clamping mechanism to return to its initial position after the material transfer is completed. The control process is similar to the material transfer process and will not be described in detail here.

[0060] Taking the transfer of material from position A to position B as an example, the working process of the material transfer device of this embodiment is described in detail as follows:

[0061] Assuming that the initial state of the device is that the clamping mechanism 14 is in the highest position, first, the horizontal movement drive 2 is started, and the horizontal movement transmission member 12 is driven to move the clamping mechanism 14 set on the sliding member 13 to above position A, and the horizontal movement drive 2 is turned off. Then, the lifting drive 6 is started to drive the first lifting transmission member 31 and the second lifting transmission member 32 to rise and fall synchronously to lower the clamping mechanism 14 along with the lifting base 5 to a height convenient for the clamping mechanism 14 to clamp the material, and the lifting drive 6 is turned off. Then, the clamping mechanism 14 is controlled to clamp the material, and then the lifting drive 6 is started again to lift the clamping mechanism 14 along with the lifting base 5 to a high place (at least to ensure that it will not be obstructed during the subsequent horizontal movement), and the lifting drive 6 is turned off again and the horizontal movement drive 2 is turned on again to move the material along with the clamping mechanism 14 to above position B, and the horizontal movement drive 2 is turned off again. Finally, the lifting drive 6 is started again to lower the material along with the clamping mechanism 14 until the material is stably placed at position B, and the clamping mechanism 14 is controlled to release the material to complete the material transfer. After the material transfer is completed, the lifting drive 6 can be started again to lift the clamping mechanism 14 to a high position to prepare for the next material transfer.

[0062] The material transfer device of this embodiment can realize the transfer of materials at different positions inside the sealed box chamber. In addition, components with high maintenance frequency, such as the lifting drive in the lifting mechanism and the horizontal moving drive in the horizontal moving mechanism, are all located outside the sealed box chamber. The maintenance frequency of the components inside the sealed box chamber is very low, which is not only easy to operate, safe and convenient, but also easy to inspect and maintain.
