[0048] In order to understand the embodiments of the present application more clearly, the following Figures 1 to 10 The embodiments of the present application are described in detail.

[0049] like Figures 3 to 10 As shown, the present application provides a transfer device 1 for transferring material 2, the transfer device 1 comprising a frame 11, a rotating assembly 12, and a holding assembly 13. The rotating assembly 12 is rotatably disposed on the frame 11; the holding assembly 13 is movably disposed on the rotating assembly 12 along a preset direction.

[0050] Material 2 can be any component that requires adjustment during transfer. For example, in battery production, material 2 can be a cap. In subsequent production steps, the cap needs to be welded to the battery's tab. After the battery is fixed, the tab is typically in a vertically extended position, requiring the cap to be moved from a horizontal position to a vertical position to achieve welding. Transfer device 1 can conveniently transfer the cap from a horizontal position to a vertical position.

[0051] The frame 11 refers to a component that is relatively stationary with respect to the ground. The frame 11 is provided to facilitate the control of the movement of components that need to move in the transfer device 1 .

[0052] Rotating assembly 12 is rotatably mounted on frame 11. The rotational connection between rotating assembly 12 and frame 11 can be a shaft connection, a universal joint connection, a screw connection, or the like. By providing rotating assembly 12, the material 2 can be rotated during the rotation of rotating assembly 12 relative to frame 11, thereby changing the posture of material 2. It should be noted that the rotation angle of rotating assembly 12 is determined by the desired posture of material 2. For example, when adjusting material 2 from a horizontal posture to a vertical posture, the rotation angle of rotating assembly 12 is 90°.

[0053] The holding component 13 is a mechanism for holding the material 2. In some embodiments, the holding component 13 can be a mechanical gripper, which can be opened and closed to grasp and place the material 2. In still other embodiments, the holding component 13 can also be an adsorption device, which can adsorb the material 2 onto the holding component 13 through the adsorption force generated by the negative pressure member. In some other embodiments, when the material 2 is made of a magnetic material, the holding component 13 can also be a magnetic device, which can magnetically adsorb the material 2 onto the holding component 13 through magnetic force; in this case, the holding component 13 can be an electromagnet or a permanent magnet, and this embodiment of the present application does not limit this.

[0054] The movable connection between the holding component 13 and the rotating component 12 can be achieved through a guide rail slider mechanism, or through a ball screw mechanism or a screw mechanism, which is not limited in this embodiment of the present application.

[0055] The preset direction refers to the radial direction with the rotation center of the rotating assembly 12 and the frame 11 as the center. Figure 1 、 3 , 4 shown in the state of the preset direction is the vertical direction, so that the holding component 13 can approach the first station 51 and hold the material 2 located on the first station 51; and when the transfer device 1 is in Figure 5 、 6 In the state shown, the preset direction is the horizontal direction, so that the holding component 13 can approach the second workstation 61 and place the material 2 on the second workstation 2.

[0056] On the one hand, by providing a rotating assembly 12, the rotation of the rotating assembly 12 can rotate the material 2 held in the holding assembly 13 to a desired posture, thereby completing the posture and position adjustment of the material 2. On the other hand, by arranging the holding assembly 13 movably along a preset direction on the rotating assembly 12, the distance between the holding assembly 13 and the material 2 can be easily adjusted during the process of holding and placing the material 2, and the rotation of the rotating assembly 12 can transfer the material 2 from one workstation to another. Grasping, rotating, and placing are all performed in the transfer device 1, which can save the time of grasping and placing the material 2 by the robot arm, and improve production efficiency.

[0057] like Figures 3 to 5 and Figure 9 、 10 In some embodiments, the rotating assembly 11 includes a mounting member 121 and a connecting member 122. The mounting member 121 is rotatably mounted on the frame 11; the connecting member 122 is movably mounted on the mounting member 121 along a predetermined direction; and the holding assembly 13 is mounted on the connecting member 122.

[0058] Similarly, the rotational connection between the mounting member 121 and the frame 11 can be achieved by a shaft connection, a universal joint connection, a screw connection, etc. The movable connection between the connecting member 122 and the mounting member 121 can be achieved by a guide rail slider mechanism, a ball screw mechanism, or a screw mechanism.

[0059] The connection method between the holding component 13 and the connecting member 122 can be a detachable connection method such as threaded connection and snap connection, or a non-detachable connection method such as welding and bonding, which is not limited in the embodiment of the present application.

[0060] The installation of the mounting member 121 and the connecting member 122 enables the installation of the rotating assembly 12 and the holding assembly 13 on the transfer device 1 , which has a simple and reliable structure.

[0061] like Figures 3 to 5 As shown, in some embodiments, a guide rail 1211 extending along a preset direction is provided on the mounting member 121, and a slider 1221 is provided on the connecting member 122, and the slider 1221 is movably provided on the guide rail 1211; or a guide rail extending along a preset direction is provided on the connecting member 122, and a slider is provided on the mounting member 121, and the slider is movably provided on the guide rail.

[0062] That is, one of the guide rail and the slider is arranged on the mounting member 121, and the other is arranged on the connecting member 122. The movable connection between the connecting member 122 and the mounting member 121 is realized by the guide rail and slider mechanism, and the structure is simple.

[0063] like Figure 9 and Figure 10 As shown, in some embodiments, the transfer device 1 further includes a drive assembly 14, which includes a first drive member 141 and a second drive member 142. The first drive member 141 is drivingly connected to the mounting member 121; the second drive member 142 is drivingly connected to the connecting member 122.

[0064] The first driving member 141 is a member that drives the mounting member 121 to rotate relative to the frame 11. Specifically, the first driving member 141 can be a motor, a gear mechanism, or the like. The first driving member 141 can also be a rack and pinion mechanism.

[0065] The second driving member 142 is a member that drives the connecting member 122 to move relative to the mounting member 121. Specifically, the second driving member 142 can be a member such as an electric cylinder, an air cylinder, or a hydraulic cylinder. For example, when the movable connection between the connecting member 122 and the mounting member 121 is a guide rail slider mechanism, the electric cylinder, air cylinder, or hydraulic cylinder can be used to push the slider to move along the guide rail. The second driving member 142 can also be a motor. For example, when the movable connection between the connecting member 122 and the mounting member 121 is a screw connection, the motor can be used to drive the screw to rotate to achieve movement of the nut relative to the screw.

[0066] like Figure 7 and Figure 8 As shown, in some embodiments, the first driving member 141 includes a gear 1411 and a rack 1412. The gear 1411 is fixedly disposed on a side of the mounting member 121 away from the connecting member 122; the rack 1412 is movably disposed on the frame 11 and meshed with the gear 1411.

[0067] The movable connection between the rack 1412 and the frame 11 can be achieved through a guide rail slider mechanism, or through a ball screw mechanism or a screw mechanism.

[0068] By providing gear 1411 and rack 1412, when rack 1412 moves relative to frame 11, it drives gear 1411 to rotate, thereby driving rotation assembly 12 to rotate. Compared to a motor drive, the rack-and-pinion mechanism converts the movement of the rack into the rotation of the gear. The gear rotates at a slower speed, making it easier to control the rotation angle of rotation assembly 12. No speed reducer is required, making the transfer device 1 simpler in structure.

[0069] like Figures 3 to 5 and Figure 7 、 8 As shown, in some embodiments, the rotating assembly 12 further includes a rotating shaft 123 that passes through the frame 11 , and one end of the rotating shaft 123 is fixedly connected to the gear 1411 , and the other end is fixedly connected to the mounting member 121 .

[0070] Similarly, the connection between the rotating shaft 123 and the gear 1411 can be a detachable connection such as a threaded connection or a snap connection, or a non-detachable connection such as welding or bonding, and the present embodiment does not limit this. The connection between the rotating shaft 123 and the mounting member 121 can be a detachable connection such as a threaded connection or a snap connection, or a non-detachable connection such as welding or bonding, and the present embodiment does not limit this.

[0071] The rotational connection between the rotating assembly 12 and the frame 11 is achieved by providing the rotating shaft 123 , and the structure is simple and reliable.

[0072] In some embodiments, the transfer device 1 further includes a rolling bearing disposed between the frame 11 and the rotating shaft 123 . By disposing the rolling bearing, the friction between the frame 11 and the rotating shaft 123 can be reduced, thereby increasing the service life of the transfer device 1 .

[0073] like Figures 3 to 10 As shown, in some embodiments, the second driving member is a pushing rod 142 rotatably disposed on the frame 11, and the pushing rod 142 includes a first pushing portion 1421. The end of the first pushing portion 1421 away from the frame 11 pushes the connecting member 122 to move along a preset direction during rotation.

[0074] The cross section of the push rod 142 can be a regular shape such as a circle or a square, or can be an irregular shape composed of a combination of line segments and / or arcs, and the embodiment of the present application does not limit this.

[0075] By setting the first pushing portion 1421, as Figure 3 and Figure 4 As shown, the push rod 142 rotates counterclockwise relative to the frame 11. At this time, the downward movement of the first pushing portion 1421 pushes the connecting member 122 downward, so that the holding component 13 is close to the material 2, which is convenient for holding the material 2.

[0076] like Figures 3 to 10 As shown, in some embodiments, the pushing rod 142 further includes a second pushing portion 1422 , which is arranged perpendicular to the first pushing portion 1421 . The end of the second pushing portion 1422 away from the frame 11 pushes the connecting member 122 to move along a preset direction during rotation.

[0077] The second pushing portion 1422 is disposed perpendicular to the first pushing portion 1421. In some embodiments, as Figure 6 As shown, the vertical foot of the second pushing portion 1422 and the first pushing portion 1421 coincides with the rotation center of the pushing rod 142 and the frame 11. In other embodiments, as Figure 7 and Figure 8 As shown, the vertical feet of the second pushing portion 1422 and the first pushing portion 1421 do not coincide with the rotation center of the pushing rod 142 and the frame 11. Figure 6 and Figure 7 As shown, the rotation angle of the rotating assembly 12 can be 90°, at which time the material 2 can be adjusted from a horizontal state to a vertical state (or the material 2 can be adjusted from a vertical state to a horizontal state); Figure 8 As shown, the rotation angle of the rotating component 12 can also be other angles, and the angle of rotation of the rotating component 12 is set according to the posture that the material 2 needs to be adjusted.

[0078] By setting the second pushing portion 1422, as Figures 6 to 8As shown, when the rotating component 12 rotates to the predetermined position, the pushing rod 142 rotates clockwise relative to the frame 11. At this time, the second pushing portion 1422 pushes the connecting member 122 to move in the preset direction, so that the holding component 13 is close to the unloading station, which facilitates the transfer of the material 2 to the next station.

[0079] like Figure 6 As shown, in some embodiments, the vertical foot of the second pushing portion 1422 and the first pushing portion 1421 coincides with the rotation center of the pushing rod 142 and the frame 11 .

[0080] The vertical feet of the second pushing portion 1422 and the first pushing portion 1421 coincide with the rotation center of the pushing rod 142 and the frame 11 , that is, the vertical feet of the second pushing portion 1422 and the first pushing portion 1421 intersect at the rotation center of the pushing rod 142 and the frame 11 .

[0081] When the material 2 is adjusted from the horizontal state to the vertical state (or from the vertical state to the horizontal state), as shown in FIG. Figure 6 As shown, when the rotating assembly 12 rotates to the predetermined position, the push rod 142 rotates clockwise relative to the frame 11. At this time, because the vertical foot of the second push portion 1422 and the first push portion 1421 coincides with the rotation center of the push rod 142 and the frame 11, the second push portion 1422 will move horizontally to the left at the moment of rotation, thereby pushing the connecting member 122 to the left, thereby moving the holding assembly 13 closer to the unloading station. In other words, after the vertical foot of the second push portion 1422 and the first push portion 1421 coincides with the rotation center of the push rod 142 and the frame 11, the entire force of the second push portion 1422 (rather than the component force) is used to push the connecting member 122 to move, thereby maximizing the driving force and achieving the most significant driving effect.

[0082] like Figures 3 to 10 As shown, in some embodiments, a first roller 1423 is provided at one end of the first pushing portion 1421 away from the frame 11 ; and / or a second roller 1424 is provided at one end of the second pushing portion 1422 away from the frame 11 .

[0083] That is, in some embodiments, the first pushing portion 1421 is provided with a first roller 1423 at one end facing away from the frame 11, or the second pushing portion 1422 is provided with a second roller 1424 at one end facing away from the frame 11; while in other embodiments, the first pushing portion 1421 is provided with a first roller 1423 at one end facing away from the frame 11, and the second pushing portion 1422 is provided with a second roller 1424 at one end facing away from the frame 11.

[0084] The first roller 1423 and the second roller 1424 are wheels that can rotate around their own axes.

[0085] By providing the first roller 1423 and / or the second roller 1424 , when the push rod 142 pushes the connecting member 122 , the sliding friction between the two can be converted into rolling friction, thereby reducing the wear between the push rod 142 and the connecting member 122 and improving the service life of the transfer device 1 .

[0086] like Figures 3 to 5 as well as Figure 9 、 Figure 10 As shown, in some embodiments, the transfer device 1 further includes an elastic member 16 , which is disposed on a side of the connecting member 122 away from the push rod 142 , and one end of the elastic member 16 abuts against the connecting member 122 , and the other end abuts against the mounting member 121 .

[0087] The elastic member 16 can be made of an elastic material such as rubber, or it can be a spring. The elastic member 16 can be removably sandwiched between two opposing surfaces of the connecting member 122 and the mounting member 121. Specifically, a recessed portion can be provided on the opposing surfaces of the connecting member 122 and / or the mounting member 121, and the elastic member 16 can be placed in the recessed portion. In this case, it should be noted that the length of the elastic member 16 should be greater than the depth of the recessed portion to ensure that the elastic member can be compressed and provide a buffering effect. Of course, the elastic member 16 can also be directly fixed to the opposing surfaces of the connecting member 122 and / or the mounting member 121.

[0088] By arranging the elastic member 16, on the one hand, when the pushing rod 142 pushes the connecting member 122 to move, it can play a buffering role to prevent the connecting member 122 and the mounting member 121 from colliding and being damaged; on the other hand, by arranging the elastic member 16 on the side of the connecting member 122 away from the pushing rod 142, when the pushing rod 142 removes the pushing force, the connecting member 142 can return to its original position under the action of the elastic force, thereby reducing the number of driving members.

[0089] like Figure 9 and Figure 10 As shown, in some embodiments, the transfer device 1 further includes a power source 17, which includes: a first cam 171 and a first connecting rod 172 and / or a second cam 173 and a second connecting rod 174. The first connecting rod 172 connects the first cam 171 and the rack 1412; the second connecting rod 174 connects the second cam 173 and the second driving member.

[0090] That is, in some embodiments, the power source 17 includes a first cam 171 and a first connecting rod 172, and a cam-connecting rod mechanism is provided to drive the rack to move. In this case, a motor, gear, etc. can be used to drive the second driving member, or a cam-connecting rod mechanism can be used to drive the second driving member; in other embodiments, the power source 17 includes a second cam 173 and a second connecting rod 174, and a cam-connecting rod mechanism is provided to drive the second driving member. In this case, a motor, electric cylinder, air cylinder, etc. can be used to drive the rack, or a cam-connecting rod mechanism can be used to drive the rack; in some further embodiments, the power source 17 includes a first cam 171, a first connecting rod 172, a second cam 173 and a second connecting rod 174, that is, a cam-connecting rod mechanism is used to drive the rack and the second driving member.

[0091] like Figure 10 As shown, by providing a first cam 171 and a first connecting rod 172 , the first cam 171 drives the first connecting rod 172 to move when it rotates, and the first connecting rod 172 drives the rack to move, thereby driving the rotating assembly 12 to rotate.

[0092] like Figure 10 As shown, by providing a second cam 173 and a second connecting rod 174 , the second cam 173 drives the second connecting rod 174 to move when it rotates, and the second connecting rod 174 drives the second driving member to rotate, thereby driving the pushing rod 142 to push the connecting member 122 .

[0093] It should be noted that when the power source 17 includes the first cam 171, the first connecting rod 172, the second cam 173, and the second connecting rod 174, the first cam 171 and the second cam 173 can be fixedly arranged on the same rotating shaft, and the rotation of the rotating shaft drives the rotation of the first cam 171 and the second cam 173, which can simplify the structure of the transfer device 1. Of course, the first cam 171 and the second cam 173 can also be fixedly arranged on different rotating shafts, and the rotation of the different rotating shafts can respectively drive the rotation of the first cam 171 and the second cam 173, thereby facilitating the control of the rotation direction and speed of the first cam 171 and the second cam 173.

[0094] like Figures 3 to 9 As shown, in some embodiments, the holding assembly includes a negative pressure portion 131 and an adsorption portion 132 connected to the negative pressure portion 131 , and the adsorption portion 132 is used to absorb the material 2 .

[0095] The negative pressure unit 131 is a component capable of providing negative pressure. The negative pressure unit 131 can provide a negative pressure environment to the adsorption unit 132, allowing the material 2 to be adsorbed on the adsorption unit 132. In some embodiments, the negative pressure unit 131 can also be a vacuum device, so that the negative pressure it provides reaches a vacuum state, thereby increasing the adsorption force of the adsorption unit 132 and improving the absorption effect of the material 2.

[0096] like Figure 1 and Figure 2 As shown, on the other hand, the present application provides a conveying system, which includes a transfer device 1, a first workstation 3 and a second workstation 4. The first workstation 3 and the second workstation 4 are located in the rotation plane of the rotating component 12, and the transfer device 1 is used to transfer the material 2 from the first workstation 3 to the second workstation 4.

[0097] The first and second workstations 3 and 4 refer to two specific fixed locations within a conveyor system. In some embodiments, the first and second workstations 3 and 4 may be locations within a process, where the corresponding production process is completed. In other embodiments, the first and second workstations 3 and 4 may be pallet fixtures installed on a conveyor line, which transfer material 2 to another location for the corresponding production process after completing the transfer.

[0098] The first station 3 and the second station 4 are located in the rotation plane of the rotating component 12, that is, before rotation, the rotating component can directly pick up the material 2 from the first station 3, and the rotating component 12 can also directly place the material on the second station 4 after rotating from the first station 3 to the second station 4. No additional mechanical gripper is required to complete the transfer of the material 2 from the first station 3 to the transfer device 1 and from the transfer device 1 to the second station 4. The transfer process is continuous and the production efficiency is high.

[0099] By providing the transfer device 1, after the holding assembly 13 grabs the material 2 at the first station 3, the rotation of the rotating assembly 12 can rotate the material 2 held in the holding assembly 12 to the second station 4. While transferring the material 2 from the first station 3 to the second station 4, the material's posture is adjusted. By changing the positions of the first station 3 and the second station 4 within the rotation plane of the rotating assembly, the transfer device 1 can adapt to the material 2's different postures, ensuring a consistent transfer action.

[0100] like Figure 1 As shown, in some embodiments, the conveying system further includes a first conveying line 5 and / or a second conveying line 6. The first conveying line 5 is provided with a plurality of first pallets 51, and the first conveying line 5 sequentially conveys the plurality of first pallets 51 to the first workstation 3; the second conveying line 6 is provided with a plurality of second pallets 61, and the second conveying line 6 sequentially conveys the plurality of second pallets 61 to the second workstation 4.

[0101] That is, in some embodiments, the conveying system includes the first conveying line 5 or the second conveying line 6 ; while in other embodiments, the conveying system includes the first conveying line 5 and the second conveying line 6 .

[0102] By providing the first conveyor line 5 and / or the second conveyor line 6, the time required for the loading and unloading of the material 2 can be transferred to other processes, thereby enabling the loading, transfer, and unloading of the material to be performed simultaneously. This avoids the situation where the loading, transfer, and unloading of the material are all performed in the transfer process, which would otherwise require separate execution, increasing production time and affecting production efficiency.

[0103] Specifically, such as Figures 1 to 10 As shown, when loading, the material 2 is placed in the first tray 51, and each first tray 51 is transported by the first conveyor line to the first workstation 3.

[0104] During transfer, the push rod 142 of the transfer device 1 rotates counterclockwise, causing the first push portion 1421 to push the holding assembly 13 toward the first station 3. Under the action of the negative pressure portion 131, the suction portion 132 absorbs the material 2 located on the first station 3. Then, the push rod 142 rotates clockwise, causing the holding assembly 13 to move away from the first station 3 under the drive of the elastic member 16. Subsequently, the rotation assembly 12 rotates, rotating the material 2 from a horizontal position to a vertical position. Finally, the push rod 142 rotates clockwise, causing the second push portion 1422 to push the holding assembly 13 toward the second station 4. The negative pressure portion 131 stops operating, and the suction portion 132 places the material 2 on the second tray 61 located in the second station 4, completing the adjustment of the material 2 from a horizontal position to a vertical position and the transfer of the material 2 from the first station 3 to the second station 4.

[0105] During unloading, the second conveyor line 6 drives the second tray 61 to move and convey the material 2 to the next process.

[0106] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
