[0039] Example:

[0040] See also Figures 1 to 4 The sheet material transportation device in the preferred embodiment of the utility model includes a first transmission mechanism 1 and a second transmission mechanism 2 arranged in sequence along a first direction, and the first transmission mechanism 1 and the second transmission mechanism 2 are both used to transport sheet materials. The transmission directions of both are the first direction, and the first transmission mechanism 1 and the second transmission mechanism 2 are arranged adjacent to each other; the present application also includes a first storage mechanism 3 and a third storage mechanism 6 located on both sides of the first transmission mechanism 1, and the first storage mechanism 3 and the third storage mechanism 6 are arranged along the second direction, and the second direction is perpendicular to the first direction; a conveying mechanism 5 is also provided above the first transmission mechanism 1, and the conveying mechanism 5 includes a conveying drive member, a conveying support frame 501 extending along the second direction, and a first adsorption component 502 and a second adsorption component 503 connected to the conveying support frame 501 and separately arranged along the second direction. Among them, the first adsorption component 502 is close to the first storage mechanism 3, and the transport drive is used to drive the first adsorption component 502 to reciprocate between the first storage mechanism 3 and the first transmission mechanism 1, and to drive the second adsorption component 503 to reciprocate between the first transmission mechanism 1 and the third storage mechanism 6; the present application also includes a second storage mechanism located below the second transmission mechanism 2, and the second transmission mechanism 2 is correspondingly connected to a lifting mechanism 4, which is used to drive the second transmission mechanism 2 to rise and fall vertically.

[0041] Specifically, the present application sets a first storage mechanism 3 and a third storage mechanism 6 on both sides of the transmission direction of the first transmission mechanism 1, and realizes the reciprocating movement between the first transmission mechanism 1 and the first storage mechanism 3 through the first adsorption component 502 of the conveying mechanism 5. When broken battery cells are transmitted on the first transmission mechanism 1, the broken battery cells can be transferred and adsorbed to the first storage mechanism 3 through the first adsorption component 502 to prevent the broken battery cells from affecting the processing of other intact battery cells on the production line. At the same time, the present application also arranges a second storage mechanism corresponding to the bottom of the second conveying mechanism 2, and arranges a lifting mechanism 4 that drives the second conveying mechanism 2 to rise and fall vertically. When the first storage mechanism 3 is fully loaded or other reasons cause the first adsorption component 502 to be unable to unload normally, the second adsorption component 503 can be used to take the intact battery cells on the first conveying mechanism 1 to the third storage mechanism 6, and after the second conveying mechanism 2 and the first conveying mechanism 1 are vertically misaligned, the broken battery cells transmitted from the first conveying mechanism 1 can fall exactly into the second storage mechanism, so as to avoid the problem that the entire sheet material transportation device needs to stop when the first storage mechanism 3 is fully loaded or other reasons cause the first adsorption component 502 to be unable to unload normally, thereby playing a role in preventing material blockage, effectively reducing the equipment failure downtime rate, and improving equipment production capacity.

[0042] It should be noted that, assuming that the two adjacent battery cells transported from the first transmission mechanism 1 are respectively an intact battery cell and a broken battery cell, if the intact battery cell is not first placed in the third storage mechanism 6 or is taken away from the first transmission mechanism 1 and then the second transmission mechanism 2 is directly raised, the intact battery cell will also fall into the third storage mechanism 6. In this way, the intact battery cell and the broken battery cell are mixed together, increasing the complexity of processing.

[0043] As an optional embodiment of the utility model, the first transmission mechanism 1 and the second transmission mechanism 2 in the present application are both conveyor belts 202, and the first storage mechanism 3, the second storage mechanism and the third storage mechanism 6 are all material boxes, and the above-mentioned first adsorption component 502 and the second adsorption component 503 are both suction cups. The sheet material transportation device in the present application is mainly used for the transmission and cleaning of sheet materials such as battery cells. The transmission belt is suitable for the transmission of battery cells, the material box structure is used for the stacking of sheet materials, and the suction cup structure can directly adsorb and transport the battery cells. It is worth noting that the broken battery cells in the present application are not a completely broken structure, which only represents a battery cell structure with notches or cracks. The broken battery cells can be directly sucked and transported by the first adsorption component 502 in the present application.

[0044] Preferably, the first conveying mechanism 1 and the second conveying mechanism 2 in the present application adopt a step-by-step transmission mode, which will pause after transmitting a unit distance to facilitate the handling mechanism 5 to remove the broken battery cells from the first conveying mechanism 1, and at the same time reserve time for the lifting mechanism 4 to lift the second conveying mechanism 2, so that the broken battery cells can be transmitted to the second storage mechanism.

[0045] Optionally, the sheet material transport device in the present application can be used not only to transport battery cells and clean up broken battery cells, but also to transport other materials that need to be cleaned of defective products.

[0046] Specifically, in the present application, the adjacent arrangement of the first transmission mechanism 1 and the second transmission mechanism 2 refers to a state in which the output end of the first transmission mechanism 1 is connected to the input end of the second transmission mechanism 2 or the gap between the two does not affect the transmission of the battery cell between the two. During the transmission process, the first transmission mechanism 1 corresponds to a certain transmission kinetic energy given to the battery cell. Even if there is a certain gap between the first transmission mechanism 1 and the second transmission mechanism 2, the battery cell can still cross the gap and be transmitted to the second transmission mechanism 2. Therefore, in the actual setting process, the gap distance between the first transmission mechanism 1 and the second transmission mechanism 2 can be adjusted according to the size of the transported battery cell to ensure the normal transmission of the battery cell.

[0047] Further preferably, the transmission path of the first transmission mechanism 1 in the present application is provided with a first station and a second station in sequence, and the first station is provided with a visual inspection mechanism 8 located above the first transmission mechanism 1, and the transport drive drives the first adsorption assembly 502 to move back and forth between the second station and the first storage mechanism 3. Specifically, the visual inspection mechanism 8 is used to take pictures to identify the state of the battery cell, such as whether it is a broken piece. When the battery cell moves on the first transmission mechanism 1, it first passes through the first station and is identified by the visual inspection mechanism 8 to see if it is a broken piece, and then moves to the second station. When the battery cell is a broken battery cell, the broken battery cell moved to the second station can be taken to the first storage mechanism 3 by the transport mechanism 5; when the battery cell is a normal battery cell, the battery cell can be transported to the next processing station by the first transmission mechanism 1 and the second transmission mechanism 2. Furthermore, when the first storage mechanism 3 is fully loaded or other reasons cause the first adsorption component 502 to be unable to unload normally, and the visual inspection mechanism 8 detects that there are broken fragments on the first station, the second adsorption component 503 will take the intact battery cells that have been moved to the second station and place them in the third storage mechanism 6, and when the broken fragments arrive at the second station, the lifting mechanism 4 drives the second transmission mechanism 2 to lift, and after the second transmission mechanism 2 is vertically misaligned with the first transmission mechanism 1, the broken fragments move from the second station to the second storage mechanism.

[0048] Optionally, the visual inspection mechanism 8 in the present application also has the function of identifying whether the battery cell is skewed, and a skewed battery cell refers to a battery cell with a large angle deviation in the battery cell position. When the visual inspection mechanism 8 identifies a skewed battery cell at the first station, the skewed battery cell at the second station can be transported to the third storage mechanism 6 through the second adsorption component 503, and then the skewed battery cell in the third storage mechanism 6 can be loaded and corrected.

[0049] Further, as a preferred embodiment of the utility model, in the second direction of the present application, the third storage mechanism 6 is further provided with a fourth storage mechanism 7 on the side away from the first transmission mechanism 1, and the transport mechanism 5 further includes a third adsorption assembly 504 connected to the transport support frame 501, the second adsorption assembly 503 is located between the first adsorption assembly 502 and the third adsorption assembly 504, and the transport drive is used to drive the third adsorption assembly 503 to and from the third storage mechanism 6 and the fourth storage mechanism 7. The fourth storage mechanism 7 is mainly used to place separators. Since the third storage mechanism 6 is used to store distorted or partially cached battery cells, the distorted and normal battery cells can also be reprocessed in subsequent processes. In order to avoid direct contact between stacked battery cells to damage the battery cells (when the battery cells are back-contact batteries, this problem will exist), a piece of separator paper needs to be placed between adjacent battery cells. Based on this, the present application is provided with a corresponding fourth storage mechanism 7, and the separator paper in the fourth storage mechanism 7 is taken out by the third adsorption assembly 504 and placed in the third storage mechanism 6, so that separator paper is placed between the vertically stacked battery cells to avoid direct contact between adjacent battery cells. Specifically, every time a good battery cell or a distorted battery cell is placed in the third storage mechanism 6, a piece of separator paper in the fourth storage mechanism 7 is taken out and placed in the third storage mechanism 6 through the third adsorption component 504, and then another battery cell is placed in the third storage mechanism 6, and this process is repeated.

[0050] Further preferably, a third conveying mechanism is provided downstream of the second conveying mechanism 2 along the first direction, and the conveying direction of the third conveying mechanism is also the first direction. The third conveying mechanism is used to receive the battery cells at the second conveying mechanism 2 and transport them to the next station. The sheet material transport device in the present application also needs to transport the battery cells to the subsequent stations for processing or other treatments. In order to ensure the stable connection between the battery cells and the subsequent stations, the present application sets the second conveying mechanism 2 to a liftable form. When the broken fragments are collected, the second conveying mechanism 2 is lowered to the same height as the first conveying mechanism 1 and the third conveying mechanism, and then the battery cells transmitted by the first conveying mechanism 1 can continue to be transmitted backward to the third conveying mechanism.

[0051] Further, as a preferred embodiment of the utility model, the lifting mechanism 4 in the present application includes a telescopic cylinder 401, which is arranged on the side of the transmission direction of the second transmission mechanism 2, and the telescopic end of the telescopic cylinder 401 is arranged vertically, and a lifting plate 402 is also arranged between the telescopic cylinder 401 and the second transmission mechanism 2, one end of the lifting plate 402 is connected to the telescopic end of the telescopic cylinder 401, and the other end is connected to the second transmission mechanism 2. In the present application, the lifting plate 402 can be driven to rise and fall vertically by the telescopic cylinder 401, and the lifting plate 402 correspondingly drives the second transmission mechanism 2 to move vertically, thereby realizing the vertical overlap or separation of the second transmission mechanism 2 and the first transmission mechanism 1. At the same time, the lifting plate 402 allows the telescopic cylinder 401 to be arranged on the side of the second transmission mechanism 2, so as to avoid the problem of mutual interference between the telescopic cylinder 401 and the second storage mechanism when the telescopic cylinder 401 is arranged below the second transmission mechanism 2, so as to ensure that after the second transmission mechanism 2 is lifted, the broken battery slices can fall into the second storage mechanism normally.

[0052] Further preferably, the lifting plate 402 in the present application includes a first end 403 and a second end 404 arranged along the second direction, wherein the first end 403 is higher than the second end 404, the first end 403 is connected to the telescopic cylinder 401, and the second end 404 is connected to the second transmission mechanism 2. Since the telescopic cylinder 401 needs to drive the second transmission mechanism 2 to rise and fall vertically, the telescopic end of the telescopic cylinder 401 is arranged vertically, which makes the overall dimension of the telescopic cylinder 401 longer in the vertical direction, while the transmission table of the first transmission mechanism 1 and the second transmission mechanism 2 are at the same height in the normal transmission state. In order to avoid the overall dimension of the telescopic cylinder 401 causing the overall table of the first transmission mechanism 1 and the second transmission mechanism 2 to rise, the present application correspondingly sets the lifting plate 402 as a high and low folding line structure, which makes the bottom surface height of the second transmission mechanism 2 lower than the telescopic end height of the telescopic cylinder 401, thereby ensuring that the installation space of the telescopic cylinder 401 is sufficient.

[0053] Further preferably, both the first transmission mechanism 1 and the second transmission mechanism 2 are conveyor belts 202. In the present application, the conveyor belt 202 of the second transmission mechanism 2 has a size in the first direction close to the size of the sheet material in the first direction to improve work efficiency. Preferably, the conveyor belt 202 of the second transmission mechanism 2 in the present application is driven to rotate by the belt drive 201 beside it, and the size of the conveyor belt 202 in the first direction is 1 to 2 times the size of the sheet material in the first direction, that is, the length of the second transmission mechanism 2 can accommodate at least one battery cell.

[0054] Correspondingly, the first adsorption assembly 502, the second adsorption assembly 503 and the third adsorption assembly 504 in the present application have the same structure, and all of them include a telescopic rod arranged vertically, one end of the telescopic rod is slidably connected to the transport support frame 501, and the transport drive is used to drive the telescopic rod to move on the transport support frame 501, and the other end of the telescopic rod is provided with an adsorption plate, and a plurality of suction cup structures are correspondingly arranged on the adsorption plate, and the battery tray is taken and placed by the suction cup structure. Optionally, in addition to the above-mentioned adsorption structure, the transport mechanism 5 in the present application can also adopt other clamping and transporting structures such as a manipulator.

[0055] In addition, it should be noted that it is preferred that the first adsorption component 502, the second adsorption component 503 and the third adsorption component 504 are moved laterally at the same time by the same drive to improve work efficiency.

[0056] The working process of the sheet material transport device in the utility model is as follows:

[0057] The visual inspection mechanism 8 identifies the battery cell that is transferred to the first conveying mechanism 1 and is located at the first station. When the battery cell is a broken battery cell, the broken battery cell is transported to the second station along the first conveying mechanism 1, and the first adsorption component 502 descends and adsorbs the broken cell. Then, the first adsorption component 502 is transported along the transport support frame 501 to the top of the first storage mechanism 3, and the first adsorption component 502 descends and delivers the broken battery cell into the first storage mechanism 3. When the first storage mechanism 3 is full of broken battery cells or other reasons cause the first adsorption component 502 to be unable to unload normally, and at this time, the first adsorption component 502 Another broken fragment is detected at a workstation, and the second adsorption component 503 adsorbs the intact battery cell in front of the broken fragment at the second workstation and transports it to the third storage mechanism 6; the broken fragment is then transported to the connection position of the first conveying mechanism 1 and the second conveying mechanism 2, the telescopic cylinder 401 drives the lifting plate 402 to lift, and the second conveying mechanism 2 rises accordingly, and the broken battery cell falls forward into the second storage mechanism as it is transported by the first conveying mechanism 1, and the telescopic cylinder 401 drives the second conveying mechanism 2 to descend, and the first conveying mechanism 1 and the second conveying mechanism 2 are at the same height again to continue conveying the battery cells.

[0058] When the visual inspection mechanism 8 identifies a normal battery cell, the battery cell is transported to the second transport mechanism 2 along with the first transport mechanism 1 , and then the battery cell is transported to the next station by the second transport mechanism 2 .

[0059] Further, as another optional embodiment of the utility model, the present application also includes a sheet material transportation device, which includes a first transmission mechanism 1 and a second transmission mechanism 2 arranged in sequence along a first direction, the first transmission mechanism 1 and the second transmission mechanism 2 are used to transport sheet materials, and the transmission direction of both is the first direction, and the first transmission mechanism 1 and the second transmission mechanism 2 are arranged adjacent to each other, and the surface of the second transmission mechanism 2 is provided with adsorption holes; and a first storage mechanism 3 located on the side of the first transmission mechanism 1, the first storage mechanism 3 is used to store fragment materials; a conveying mechanism 5 is also provided above the first transmission mechanism 1, the conveying mechanism 5 includes a conveying drive member, a conveying support frame 501 extending along the second direction, and a first adsorption component 502 connected to the conveying support frame 501, the conveying drive member is used to drive the first adsorption component 502 to reciprocate between the first storage mechanism 3 and the first transmission mechanism 1, so as to transport the fragment materials transmitted on the first transmission mechanism 1 to the first storage mechanism 3; a second storage mechanism is also provided below the second transmission mechanism 2, and the second transmission mechanism 2 is correspondingly connected to a lifting mechanism 4, and the lifting mechanism 4 is used to drive the second transmission mechanism 2 to rise and fall vertically.

[0060] Specifically, the present application sets a first storage mechanism 3 beside the first conveying mechanism 1, and realizes the reciprocating movement of sheet materials between the first storage mechanism 3 and the first conveying mechanism 1 through the handling mechanism 5, so as to transfer the broken battery cells on the first conveying mechanism 1 to the first storage mechanism 3, so as to avoid the broken battery cells being transported to the next processing station through the second conveying mechanism 2; at the same time, when the first storage mechanism 3 is fully loaded and needs to be replaced or other reasons cause the first adsorption component 502 to be unable to unload normally, the previous intact battery cell of the broken piece is first transported to the second conveying mechanism 2, and the adsorption hole of the second conveying mechanism 2 adsorbs the battery cell, and then the second conveying mechanism 2 is driven to rise through the lifting mechanism 4, and the broken battery cell located at the second station on the first conveying mechanism 1 is transferred to the second storage mechanism; then the second conveying mechanism 2 descends back to its position, and the intact battery cell previously adsorbed on the second conveying mechanism 2 can continue to be transported to the next station, which improves the cleaning efficiency of the production line for broken battery cells without affecting the overall transportation efficiency of the battery cells.

[0061] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
