In the prior art, manual collection is usually adopted.

[0043] The embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0044] like Figure 1-Figure 3 As shown, the utility model proposes a battery cell conveying device, including a conveying mechanism 10, a rotating mechanism 20 and a collecting mechanism 40: wherein the conveying mechanism 10 includes a plurality of conveying lines for conveying battery cells 60; the rotating mechanism 20 includes a rotating motor 22 connected to the conveying mechanism 10, and the rotating motor 22 can drive the conveying mechanism 10 to rotate to adjust the conveying direction; specifically, the conveying mechanism 10 has a first working state and a second working state, when it is in the first working state, the conveying mechanism 10 conveys the battery cell 60 to the automated production line 80; when the rotating mechanism 20 drives the conveying mechanism 10 to rotate, the conveying mechanism 10 is in the second working state, at which time the conveying mechanism 10 conveys the battery cell 60 to the collecting mechanism 40. The collecting mechanism 40 includes a detachable material box 41 for collecting the battery cell 60; when the conveying mechanism 10 is in the second working state, the battery cell 60 is conveyed into the material box 41 to complete the collection of the battery cell 60.

[0045] In the present application, the cell conveying device is arranged between two production processes, and its function is to transfer the cell 60 from the previous production process to the automated production line 80 of the next production process; the conveying mechanism 10 has a feeding end and a discharging end, and the cell 60 enters the feeding end after the previous production process is completed, and moves to the discharging end through the conveying line. When the automated production line 80 of the next production process is operating normally, the conveying mechanism 10 is in the first state, and its discharging end is aligned with the input end of the automated production line 80, so that the cell 60 enters the next production process; when ... the discharging end is aligned with the input end of the automated production line 80, so that the cell 60 enters the next production process; when the automated production line 80 of the next production process is operating normally, the conveying mechanism 10 is in the first state, and the discharging end is aligned with the input end of the automated production line 80, so that the cell 60 enters the next production process; when the automated production line 80 is operating normally, the conveying mechanism 10 is in the first When the production line 80 fails to operate normally, the angle of the conveying mechanism 10 is adjusted by the rotating mechanism 20, so that the conveying mechanism 10 is in the second working state. In this state, the discharge end is aligned with the material box 41, driving the battery cells 60 into the material box 41, completing the collection of the battery cells 60, and then transferring the material box 41 as a whole to the next production process, thereby achieving the continuity of the production operation. Compared with the manual collection method, the collection efficiency of the battery cells 60 is significantly improved. At the same time, it has a high degree of automation and can realize continuous operation, and is not easy to cause damage to the battery cells 60.

[0046] like Figure 1 As shown, the rotating mechanism 20 also includes a rotating bracket 21 and a mounting seat 23; the conveying mechanism 10 is fixed to the rotating bracket 21; the mounting seat 23 is arranged at both ends of the rotating bracket 21, for fixing the rotating motor 22; the output end of the rotating motor 22 is connected to the side of the rotating bracket 21 close to the feeding end of the conveying mechanism 10 through a coupling 24 to drive the rotating bracket 21 to rotate, and then drive the discharging end of the conveying mechanism 10 to rotate downward and align with the material box 41, so that the battery cell 60 can enter the material box 41 through the tree hole mechanism.

[0047] The rotating bracket 21 in the present application can be a frame plate of an integrated structure, or it can be a plurality of strip-shaped slats or rods, as long as the conveying mechanism 10 can be fixed; in the present embodiment, the rotating bracket 21 includes two side panels and an elongated support plate, and the two side panels are respectively arranged on both sides of the length direction of the elongated support plate; the mounting seat 23 is provided with at least one side panel, one end of the coupling 24 is connected to the side panel of the rotating bracket 21, and the other end passes through the side panel of the mounting seat 23 and is connected to the output end of the rotating motor 22, and the two rotating motors 22 rotate synchronously to drive the rotating bracket 21 to rotate; the rotating motor 22 provides sufficient driving force for the rotating bracket 21, so that its rotation process is stable, smooth, and easier to control.

[0048] The conveying mechanism 10 in the present application can be any device that can drive the battery cell 60 to be transported; in this embodiment, Figure 4 , Figure 5As shown, the conveying mechanism 10 includes a plurality of conveying belts 11 and conveying motors 12 to form a plurality of conveying lines; the conveying belts 11 are evenly arranged along a direction perpendicular to the length of the long strip pallet and are fixed to the long strip pallet through a conveying frame, so as to drive the battery cell 60 to move.

[0049] In the present application, there is a sufficient distance between the rotating bracket 21 and the collecting mechanism 40, and they are staggered in the vertical direction to accommodate the rotation of the rotating bracket 21;

[0050] Furthermore, the present application also includes a correction mechanism 30, which includes a correction base plate 31, a first guide rail 33 and a correction motor 32; the mounting seats 23 are all fixed on the correction base plate 31; the first guide rail 33 is arranged along a transmission direction perpendicular to the battery cell 60 and is located at the lower part of the correction base plate 31; the correction motor 32 drives the correction base plate 31 to slide back and forth along the first guide rail 33, driving the conveying mechanism 10 to move back and forth to achieve adjustment of the position of the battery cell 60.

[0051] Normally, the position of the conveyor line should correspond to the position of the battery cell 60 after it is output from the previous production process. However, in the actual production process, it is difficult to avoid the battery cell 60 from being offset. In this case, it is difficult for the battery cell 60 to enter the conveyor line, and it is easy to be damaged or even cause the conveying mechanism 10 to stop operating. By setting up a correction mechanism 30, when the position of the battery cell 60 and the conveyor line is offset, the conveyor mechanism 10 is adjusted to move the position of the conveyor line to align with the battery cell 60, so that the battery cell 60 can smoothly enter the conveyor line. Then the correction mechanism 30 adjusts the conveyor mechanism 10 again to return the conveyor line to the initial position, so as to adjust the position of the battery cell 60, so that the battery cell 60 can enter the material box 41 or the input end of the automated production line 80 through the conveyor line, thereby ensuring the continuity of the production operation and the quality of the battery cell 60.

[0052] Furthermore, the correction mechanism 30 also includes a displacement sensor 34 for detecting the offset between the battery cell 60 and the conveyor line, and faces the conveyor mechanism 10 to detect the position of all conveyor lines and battery cells 60 on the conveyor mechanism 10. When the displacement sensor 34 detects that the position of a column of battery cells 60 at the output end of the previous production process is offset, the offset direction and offset signals are transmitted to the controller, and the controller controls the correction mechanism 30 to operate, so that the correction bottom plate 31 drives the conveyor line to move to the position of the battery cell 60, so that the battery cell 60 can enter the conveyor line smoothly, and then the correction mechanism 30 adjusts the conveyor line back to the initial position again to adjust the position of the battery cell 60. In this application, the movement displacement and movement speed of the correction mechanism 30 are coordinated with the position and transmission speed of the battery cell 60, that is, the first displacement is completed before the battery cell 60 enters the conveyor line, and the second displacement is completed before the battery cell 60 leaves the conveyor line, so that the battery cell 60 can realize automatic position correction during the transmission process, and the correction process is fast, accurate and reliable.

[0053] Furthermore, the collecting mechanism 40 further includes a second guide rail 42, and the material box 41 is slidably connected to the second guide rail 42 to realize the transfer of the material box 41 as a whole to the next production process. When the material box 41 is full of battery cells 60, the material box 41 is pulled out from one end of the slide rail and replaced with a new material box 41, and the material box 41 full of battery cells 60 is transferred to the next production process, so that continuous operation can be realized.

[0054] Furthermore, the material box 41 is provided with a plurality of silos 411 arranged in alignment with the conveyor belt 11, and the bearing surface of the silos 411 is parallel to the conveyor line when the conveying mechanism 10 is in the second working state. In this embodiment, when the conveying mechanism 10 is in the first working state, the conveyor line is in a horizontal state; when the conveying mechanism 10 is in the second working state, the discharge end of the conveyor line is tilted downward, and the bearing surface of the silo 411 away from the conveying mechanism 10 is also tilted downward, and the two are tilted at the same angle, so that the battery cell 60 enters the silo 411 without changing the transmission direction, avoiding damage to the battery cell 60; and the entrance of the silo 411 is lower than the discharge end of the conveyor belt, so as to ensure that the next battery cell 60 can be neatly stacked on the previous battery cell 60. It can be understood that when the conveying mechanism 10 is in the first working state, the entrance of the silo 411 is also lower than the discharge end of the conveyor belt. In this embodiment, the tilt angle of the bearing surface of the silo 411 is the rotation angle of the conveying structure 10.

[0055] In this embodiment, the silo 411 is a square box body with an opening, which has three side surfaces and a supporting surface, wherein two opposite side surfaces correspond to the width direction of the battery cell 60, and the distance between the two side surfaces is greater than the specification width of the battery cell 60, so that the battery cell 60 can smoothly enter the silo 411.

[0056] In this embodiment, the rotating bracket 21 has a cavity for installing the conveying motor 12. Each conveying line is equipped with a conveying motor 12. The conveying motor 12 is placed in the rotating bracket 21. At the same time, the discharge end of the conveyor belt 11 extends to the outside of the rotating bracket 21, so that the rotating bracket 21 will not cause obstruction to the rotation of the discharge end of the conveyor belt 11.

[0057] Furthermore, the first guide rail 33, the second guide rail 42 and the correcting motor 32 are all fixed to the same base plate 50, and the correcting motor 32 is fixed between the first guide rail 33 and the second guide rail 42, and is connected to the correcting base plate 31 through the connecting plate 35; because the discharge end of the conveyor belt 11 extends to the outside of the rotating bracket 21 and is aligned with the material box 41 after rotation, there is enough space between the rotating bracket 21 and the material box 41 for installing the correcting motor 32, which can not only reduce the volume of the overall device, but also help to protect the correcting motor 32 and ensure its precise operation.

[0058] In this embodiment, the displacement sensor 34 is also fixed to the base plate 50 and is respectively arranged on the outside of the two mounting seats 23 through a bracket. One end of the bracket on which the displacement sensor 34 is installed extends toward the direction of the conveying mechanism 10, so that the displacement sensor 34 can detect the positions of all battery cells 60.

[0059] In this embodiment, in order to keep the material box 41 fixed during the collection of battery cells 60, the material box 41 is fixed to the bottom plate 50 by a positioning piece. When the material box 41 is full of battery cells 60, the positioning piece is removed to facilitate the removal of the material box 41 through the second guide rail 42. At the same time, the material box 41 has a handle for the operator to hold.

[0060] Furthermore, the rotating motor 22, the displacement sensor 34 and the correcting motor 32 are all connected to the controller, which is used to control the rotation of the rotating bracket 21, realize the conversion between the first working state and the second working state of the conveying mechanism 10, and control the movement of the correcting base plate 31 to adjust the position of the battery cell 60.

[0061] A production device provided with the battery sheet conveying device as described above, such as Figure 6 , Figure 7As shown, it includes a dryer 70, several battery cell conveying devices and an automated production line 80; when the conveying mechanism 10 of the battery cell conveying device is in the first working state, the output end of the dryer 70, the conveyor belt 11 of the conveying mechanism 10 and the input end of the automated production line 80 are aligned in sequence to realize the transmission of the battery cell 60; at the same time, the collecting mechanism 40 of the battery cell conveying device is located below the input end of the automated production line 80. When the automated production line 80 fails, the conveying mechanism 10 rotates to align with the material box 41. After the battery cell 60 is collected by the material box 41, the material box 41 is moved out of the whole and transferred to the next production process.

[0062] In this embodiment, a plurality of cell conveying devices are installed on the outer wall of the dryer 70 and are arranged one-to-one corresponding to the output ends of the dryer 70 .

[0063] A battery cell conveying device proposed in the present application integrates the functions of battery cell transmission and collection. When an automated production line fails, the conveying mechanism can be rotated through a rotating mechanism to align with the collecting mechanism, thereby realizing automated collection of the battery cells. Compared with manual collection of battery cells, the battery cell collection efficiency is significantly improved; by setting up a correction mechanism, the position of the battery cell can be adjusted in time to ensure smooth transmission of the battery cell; whether it is the transmission process or the collection process of the battery cell, there is no need to frequently stop the transmission of the battery cell, thereby realizing continuous operation.

[0064] The present application also proposes a production equipment equipped with the battery cell conveying device, which forms a combined structure with a dryer and an automated production line. It can not only transfer the battery cells to the automated production line, but also adjust the position of the battery cells. Moreover, when the automated production line fails, the battery cells can be automatically collected. The working state of the battery cell conveying device is converted through a controller, and the degree of automation is high and safe and controllable, ensuring the continuity of production operations.

[0065] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
