[0039] This application provides a transfer device 10, such as... Figures 1 to 3 As shown, the transfer device 10 includes a frame 100, a material transfer mechanism 200, and a moving mechanism 300. The material transfer mechanism 200 includes a first gripping component 210 and a second gripping component 220. The moving mechanism 300 is used to drive the material transfer mechanism 200 to move relative to the frame 100. The first gripping component 210 grips the material 20 in the first material box 400 and flips the gripped material 20. The second gripping component 220 grips the flipped material 20 on the first gripping component 210 and places the flipped material 20 in the second material box 500. By designing the first gripping component 210 and the second gripping component 220 to cooperate, the transfer device 10 can automatically flip and transfer the material 20, eliminating the need for manual flipping and transfer of the material 20 in the first material box 400. This saves labor costs, improves production efficiency, and avoids damage such as scratches to the material 20 during the material transfer process without human contact.

[0040] In some embodiments, the transfer device 10 can be used in the production process of an electronic atomizing device. For example, the material 20 can be a liquid storage component of the electronic atomizing device, and the transfer device 10 can be used for the flipping and transfer of the liquid storage component.

[0041] In some embodiments, the first gripping component 210 is rotatable relative to the second gripping component 220. The first gripping component 210 is configured to flip between a first position and a second position. When the first gripping component 210 flips from the first position to the second position, it can cause the gripped material 20 to flip. When the first gripping component 210 flips from the second position to the first position, it can grip the material 20 in the first material box 400.

[0042] In some embodiments, the moving mechanism 300 can drive the material transfer mechanism 200 to move between the first material box 400 and the second material box 500.

[0043] In some embodiments, the first gripping component 210 may be rotated 180° from the first position toward the second gripping component 220 to the second position, and the first gripping component 210 may also be rotated 180° from the second position toward the direction away from the second gripping component 220 to the first position.

[0044] In some embodiments, the first position and the second position of the first gripping component 210 may be located on the same horizontal plane. When the first gripping component 210 is in the second position, the height of the first gripping component 210 is lower than that of the second gripping component 220. The first gripping component 210 is flipped downwards to avoid the second gripping component 220 during the flipping process.

[0045] In some embodiments, the material transfer mechanism 200 further includes a support 230, a moving mechanism 300 connected between the frame 100 and the support 230, a first gripping assembly 210 and a second gripping assembly 220 mounted on the support 230, and the first gripping assembly 210 and the support 230 being rotatably connected. The moving mechanism 300 drives the support 230 to move relative to the frame 100, thereby causing the first gripping assembly 210 and the second gripping assembly 220 to move relative to the frame 100.

[0046] In some embodiments, the material transfer mechanism 200 further includes a second drive assembly 240, which drives the first gripping assembly 210 to rotate. The second drive assembly 240 is mounted on the bracket 230 and is connected between the bracket 230 and the first gripping assembly 210.

[0047] In some embodiments, such as Figure 4 As shown, the second drive assembly 240 includes a first pulley 241, a second pulley 242, and a transmission belt 243. The transmission belt 243 is connected between the first pulley 241 and the second pulley 242. The first pulley 241 is fixedly connected to the first clamping assembly 210. The second pulley 242 is mounted on a bracket 230. A drive motor 244 is mounted on the bracket 230. The drive motor 244 is used to drive the second pulley 242 to rotate, so that the second pulley 242 drives the first pulley 241 to rotate through the transmission belt 243, thereby causing the first pulley 241 to drive the first clamping assembly 210 to flip.

[0048] In some other embodiments, the drive motor 244 can also be directly connected to the first gripping component 210, so that the drive motor 244 directly drives the first gripping component 210 to flip.

[0049] In some embodiments, the drive motor 244 can rotate forward or reverse so that after the first gripping component 210 is flipped from the first position to the second position in a counterclockwise direction, it can be flipped from the second position to the first position in a clockwise direction.

[0050] In some other embodiments, the first gripping component 210 may also rotate in only one direction, rotating 180° to flip over and then rotating 360° to return to its original position.

[0051] In some embodiments, such as Figure 3As shown, the material transfer mechanism 200 includes a third drive assembly 250, which is connected between the second gripping assembly 220 and the bracket 230. The third drive assembly 250 is used to drive the second gripping assembly 220 to move along the first direction Z, so that the second gripping assembly 220 moves toward the material 20 flipped on the first gripping assembly 210. The third drive assembly 250 is also used to drive the second gripping assembly 220 to move along the first direction Z, so that the material 20 gripped by the second gripping assembly 220 moves toward the second material box 500. The first direction Z is the vertical direction. When the first gripping component 210 is in the second position, the third driving component 250 can drive the second gripping component 220 to descend relative to the first gripping component 210 to grip the material 20 that has been flipped on the first gripping component 210. After the second gripping component 220 grips the material 20, the first gripping component 210 can be flipped from the second position to the first position to avoid the second gripping component 220 in the vertical direction. The third driving component 250 can drive the second gripping component 220 to descend so that the second gripping component 220 is at least partially lower than the first gripping component 210 to place the material 20 in the second material box 500.

[0052] In some embodiments, the third drive component 250 is an electric slide, which can drive the second gripping component 220 to rise and fall relative to the bracket 230.

[0053] In some embodiments, such as Figure 7 As shown, the moving mechanism 300 includes a first conveying member 310, a second conveying member 320, and a mounting member 330. The mounting member 330 is slidably connected to the frame 100, and the material transfer mechanism 200 is slidably connected to the mounting member 330. The first conveying member 310 is connected between the mounting member 330 and the frame 100, and the second conveying member 320 is connected between the material transfer mechanism 200 and the mounting member 330. The first conveying member 310 is used to drive the mounting member 330 to move relative to the frame 100 along the second direction Y, so that the mounting member 330 drives the material transfer mechanism 200 to move between the first material box 400 and the second material box 500. The second conveying member 320 is used to drive the material transfer mechanism 200 to move relative to the mounting member 330 along the first direction Z, where the first direction Z is vertical and the first direction Z is perpendicular to the second direction Y. The first conveyor 310 and the second conveyor 320 cooperate to allow the material transfer mechanism 200 to move in the YZ plane, so that the material transfer mechanism 200 can move between the first material box 400 and the second material box 500 in the horizontal direction, and achieve lifting and lowering in the vertical direction to clamp or place the material 20.

[0054] In some embodiments, the second conveyor 320 is connected between the bracket 230 and the mounting member 330. The second conveyor 320 is used to drive the bracket 230 to move relative to the mounting member 330 along the first direction Z, so as to drive the first clamping assembly 210 and the second clamping assembly 220 to move along the first direction Z.

[0055] In some embodiments, the first conveyor 310 and the second conveyor 320 are linear guides, the extension direction of the first conveyor 310 is the second direction Y, and the extension direction of the second conveyor 320 is the first direction Z.

[0056] In some embodiments, the frame 100 includes a first frame 110 and a second frame 120 arranged in parallel, the mounting member 330 is flat and connected between the first frame 110 and the second frame 120, and the material transfer mechanism 200, the first material box 400 and the second material box 500 are disposed in the space between the first frame 110 and the second frame 120.

[0057] In some other embodiments, the moving mechanism 300 further includes a third conveying component, the first conveying member 310 and the third conveying component are slidably connected, the third conveying component is used to drive the first conveying member 310 to move relative to the frame 100 along a third direction, the third direction is perpendicular to the plane containing the first direction Z and the second direction Y, the first direction Z, the second direction Y and the third direction constitute a three-dimensional space, the moving mechanism 300 can drive the material transfer mechanism 200 to move in the three-dimensional space.

[0058] In some embodiments, such as Figure 2 As shown, the material transfer mechanism 200 also includes a pressing component 260, which is used to flatten the material 20 placed in the second material box 500. Specifically, the material 20 may be elliptical in shape. When the second gripping component 220 places the material 20 into the second material box 500, the material 20 may be uneven. The pressing component 260 can press down to flatten the material 20, ensuring that the material 20 is placed flat so that the material 20 in the second material box 500 can be directly used in the next process.

[0059] In some embodiments, such as Figure 2 and Figure 6 As shown, the pressing component 260 is installed on the second clamping component 220. When the third drive component 250 drives the second clamping component 220 to rise and fall, the pressing component 260 can follow the second clamping component 220 to rise and fall. The pressing component 260 includes a pressing member 261 and a fourth drive component 262. The fourth drive component 262 is used to drive the pressing member 261 to move toward the second material box 500, so that the pressing member 261 presses against the material 20 transferred to the second material box 500.

[0060] In some embodiments, a fourth driving component 262 is connected between the second clamping component 220 and the pressing member 261. The fourth driving component 262 is used to drive the pressing member 261 to move relative to the second clamping component 220 along a first direction Z. The second clamping component 220 is provided with a clamping space 2201. The pressing member 261 is configured to be inserted into the clamping space 2201 when the second clamping component 220 clamps the material 20. When the second clamping component 220 clamps the material 20, the pressing member 261 is located above the material 20. When the second clamping component 220 places the material 20 into the second material box 500, the fourth driving component 262 drives the pressing member 261 to press down, pressing the material 20 against the second material box 500, so that the material 20 is flat.

[0061] In some embodiments, the process of the transfer device 10 flipping and transferring the material 20 includes the following steps:

[0062] Step 1: As Figure 2 As shown, the first conveyor 310 and the second conveyor 320 drive the material transfer mechanism 200 to move above the first material box 400. The second drive assembly 240 drives the first gripping assembly 210 to rotate 180° to the first position so that the first gripping assembly 210 grips the material 20 in the first material box 400. At this time, the material 20 gripped by the first gripping assembly 210 is in its original state.

[0063] Step Two: The first conveyor 310 drives the material transfer mechanism 200 to move above the second material box 500; simultaneously, as Figure 3 As shown, the second drive assembly 240 drives the first gripping assembly 210 to rotate 180° to the second position. At this time, the material 20 also rotates 180° with the first gripping assembly 210 from its original state to its flipped state; as Figure 4 As shown, the third drive component 250 drives the second gripping component 220 to descend to a designated position to clamp the material 20 held by the first gripping component 210. At this time, the first gripping component 210 releases the material 20.

[0064] Step 3: As Figure 5 As shown. The second drive assembly 240 drives the first gripping assembly 210 to rotate 180° to the first position, and the second conveyor 320 drives the material transfer mechanism 200 to move to the designated position above the second material box 500; the third drive assembly 250 drives the second gripping assembly 220 to descend, and the second gripping assembly 220 places the material 20 into the second material box 500 and then releases it; the fourth drive assembly 262 drives the pressing member 261 to press down and flatten the material 20, ensuring that the material 20 is placed flat.

[0065] Repeat the above steps so that the transfer device 10 transfers all of the material 20 from the first material box 400 to the second material box 500.

[0066] In some embodiments, such as Figure 2 As shown, the first gripping assembly 210 includes a first connector 212 and a plurality of first gripping members 211 disposed on the first connector 212. The first gripping members 211 are used to grip the material 20. The first connector 212 is used to simultaneously drive the plurality of first gripping members 211 to flip. The second gripping assembly 220 includes a plurality of second gripping members 221. The number of second gripping members 221 is the same as the number of first gripping members 211, and the positions of the first gripping members 211 and the positions of the second gripping members 221 are set in a one-to-one correspondence.

[0067] In some embodiments, the second clamping component 220 includes a second connector 222, and the second clamping component 221 is at least partially fixedly connected to the second connector 222. A third driving component 250 is disposed between the second connector 222 and the bracket 230. The third driving component 250 is used to drive the second connector 222 to rise and fall, thereby driving the second clamping component 221 to rise and fall.

[0068] In some embodiments, the fourth drive assembly 262 is connected between the second connector 222 and the pressing member 261. There can be two fourth drive assemblies 262, with each of the two fourth drive assemblies 262 connected to one end of the second connector 222. Figure 6 As shown, the pressing member 261 includes a connecting portion 2611 and a plurality of pressing portions 2612 fixedly connected to the connecting portion 2611. The connecting portion 2611 may be elongated and connected between two fourth drive components 262. The pressing portions 2612 may be rod-shaped and arranged along the length of the connecting portion 2611. The connecting portion 2611 is inserted into the clamping space 2201 of the plurality of second clamping members 221. The positions of the pressing portions 2612 correspond one-to-one with the positions of the second clamping members 221. The pressing portions 2612 are used to press against the material 20 respectively. The fourth drive components 262 are used to drive the connecting portion 2611 to press down, thereby driving the pressing portions 2612 to press against the material 20.

[0069] In some embodiments, the first material box 400 and the second material box 500 may be rectangular, and both the first material box 400 and the second material box 500 are provided with a plurality of receiving slots for placing materials 20. The plurality of receiving slots on the first material box 400 and the second material box 500 may be arranged in rows and columns, with the receiving slots in each row arranged in a direction perpendicular to the second direction Y. The arrangement direction of the plurality of first gripping members 211, the arrangement direction of the plurality of second gripping members 221 and the arrangement direction of the receiving slots in each row are parallel, so that the first gripping component 210 can simultaneously grip an entire row of materials 20 from the first material box 400, and the second gripping component 220 can simultaneously place an entire row of materials 20 into the second material box 500.

[0070] In some embodiments, the number of first grippers 211 and second grippers 221 can both be 12, so as to simultaneously flip and transfer 12 materials 20. In some other embodiments, the number of first grippers 211 can also be 1, 3, 6, 15, 20, or any value between the above numbers.

[0071] In some embodiments, the first gripper 211 and the second gripper 221 can be pneumatic grippers, which are devices that use compressed air as power to grip or hold workpieces. In some other embodiments, the first gripper 211 and the second gripper 221 can also be electrically driven to grip the material 20.

[0072] In some embodiments, the fourth drive component 262 may be a pressure member 261 driven by compressed air or electricity to press against the material 20.

[0073] The transfer device 10 provided in this application, by setting a first clamping component 210 and a second clamping component 220, can realize the flipping and transfer of material 20 from the first material box 400 to the second material box 500, thereby achieving automated flipping and transfer of material 20, improving the transfer efficiency of material 20, saving labor costs, and increasing production efficiency. At the same time, it reduces the contact between people and material 20, ensuring the integrity of material 20, which is conducive to improving product quality.
