The adhesive film on the surface of the film sheet is torn off by a gluing device and the film sheet is pasted on the predetermined surface of the battery cell.

[0003] The currently used sheet feeding device conveys the storage rack along one direction. The storage rack full of film sheets moves from one end of the sheet feeding device to the feeding station first, and then the empty storage rack is conveyed from the feeding station to the other end of the sheet feeding device. In this way, two groups of workers or robotic arms need to be arranged at both ends of the sheet feeding device to complete the loading and unloading of the storage rack, resulting in high costs, and the entire sheet feeding device also occupies too much space in its extending direction. Utility Model Content

After the storage rack moves above the second station, through the setting of the second lifting piece, the storage rack at the same height transferred from the first station can be received more smoothly. After the second lifting piece receives the storage rack, it drives the storage rack to move down until the storage rack lands on the second conveying component so that it can be continuously transported by the second conveying component.

[0011] Optionally, rolling pieces are provided at the tops of the first lifting piece and / or the second lifting piece. The first lifting piece and / or the second lifting piece are in rolling cooperation with the bottom of the storage rack through the rolling pieces.

[0019] Optionally, the lifting mechanism includes a lifting drive member, a telescopic drive member and a lifting member. The telescopic drive member is transmission-connected to the lifting drive member and is arranged on the side of the loading station.

[0040] Some embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present application and are not intended to limit the protection scope of the present application.

[0041] During the production process of a battery module, it is necessary to paste a film on a predetermined surface of a battery cell. The film sheet for pasting is first stacked and stored on a storage rack, and then the film sheet on the storage rack is conveyed to a predetermined loading position through a sheet loading device. The adhesive film on the surface of the film sheet is torn off by a film pasting device and the film sheet is pasted on the predetermined surface of the battery cell.

[0042] The currently used sheet loading device conveys the storage rack along one direction. The storage rack full of film sheets first moves from one end of the sheet loading device to the loading station, and then the empty storage rack is conveyed from the loading station to the other end of the sheet loading device. In this way, it is necessary to arrange two groups of workers or robotic arms at both ends of the sheet loading device to complete the loading and unloading of the storage rack, which is costly, and the entire sheet loading device also occupies too much space in its extending direction.

[0043] Based on this, the present application provides a sheet loading device. Through the first conveying component and the second conveying component which are arranged in parallel and convey in opposite directions, it is possible to complete the loading of the full storage rack and the unloading of the empty storage rack on the same side of the first conveying component and the second conveying component, effectively reducing the use cost of the sheet loading device; moreover, the first conveying component and the second conveying component can also respectively control the feeding of the full storage rack and the discharging of the empty storage rack, thereby improving the transportation efficiency of the storage rack on the sheet loading device. Among them, the first station and the second station are transfer stations. Through the setting of the transfer component, it is possible to complete the transfer of the storage rack from the first station to the second station, thereby cooperating with the first conveying component and the second conveying component to form a continuous U-shaped transportation track.

[0044] The following will specifically elaborate on the present application through specific embodiments.

[0045] Refer to Figures 1 to 8 As shown, this embodiment provides a sheet loading device, including: a first conveying component 11, a second conveying component 12 and a transfer component 13. The first conveying component 11 is used to convey the storage rack 6 storing the sheet 7 from the feeding end along the first direction to the first station 81; the transfer component 13 is used to transfer the storage rack 6 located at the first station 81 along the second direction to the second station 82; the second conveying component 12 is used to convey the storage rack 6 located at the second station 82 along the third direction to the loading station 84 to supply the sheet 7, and the second conveying component 12 is also used to convey the empty storage rack 6 located at the loading station 84 from the loading station 84 along the third direction to the discharging end; the first direction is opposite to the third direction, and both the first direction and the third direction are perpendicular to the second direction; the feeding end and the first station 81 are respectively located at both ends of the first conveying component 11, and the discharging end and the second station 82 are respectively located at both ends of the second conveying component 12.

[0046] The sheet feeding device provided in this embodiment can complete the feeding work of the fully loaded storage rack 6 and the discharging work of the empty storage rack 6 on the same side of the first conveying component 11 and the second conveying component 12 through the first conveying component 11 and the second conveying component 12 that are arranged in parallel and convey in opposite directions, effectively reducing the use cost of the sheet feeding device; moreover, the first conveying component 11 and the second conveying component 12 can also respectively control the feeding of the fully loaded storage rack 6 and the discharging of the empty storage rack 6, thereby improving the transportation efficiency of the storage rack 6 on the sheet feeding device. Among them, the first station 81 and the second station 82 are transfer stations. Through the setting of the transfer component 13, the transfer work of the storage rack 6 from the first station 81 to the second station 82 can be completed, thereby cooperating with the first conveying component 11 and the second conveying component 12 to form a continuous U-shaped transportation track.

[0047] Specifically, the first direction and the third direction can both be horizontal directions to ensure that the fully loaded or empty storage rack 6 can smoothly transport the film sheet 7 on the first conveying component 11 and the second conveying component 12. Among them, the second direction can be a horizontal direction, so that the first conveying component 11, the transfer component 13 and the second conveying component 12 form a U-shaped transportation track on the horizontal plane. The second direction can also be a vertical direction, so that the first conveying component 11, the transfer component 13 and the second conveying component 12 form a U-shaped transportation track on the vertical plane. That is to say, the second conveying component 12 can be located directly above the first conveying component 11. When the fully loaded storage rack 6 moves to the first station 81, the transfer component 13 lifts the storage rack 6 at the first station 81 upward to the second station 82. At this time, the second conveying component 12 is located above the first conveying component 11, which can prevent the first conveying component 11 from blocking the feeding station 84 and affecting the feeding work of the film sheet 7 at the feeding station 84; further, the second conveying component 12 can also be located diagonally above or diagonally below the first conveying component 11. At this time, the second direction is an inclined direction at a certain angle with the vertical direction. The second direction can be perpendicular to the first direction and the third direction, or can form an acute angle or an obtuse angle with the first direction and the third direction.

[0048] In some embodiments, the first conveying component 11 and the second conveying component 12 can be conveyor belts or other conveying structures.

[0049] Continue to refer to Figures 1 to 5As shown, the transfer assembly 13 includes a transfer member 131 and a transfer driving member 132. The transfer member 131 is installed at the driving end of the transfer driving member 132. The transfer driving member 132 drives the transfer member 131 to reciprocate in the second direction, so as to drive the transfer member 131 to push the storage rack 6 at the first station 81 to the second station 82. Specifically, the transfer member 131 can be a plate-like structure, which pushes the side surface of the storage rack 6 in the horizontal direction, so as to realize the movement of the storage rack 6 along the horizontal second direction. The transfer member 131 can also be a structure that supports the bottom of the storage rack 6 in the vertical direction, so as to realize the movement of the storage rack 6 along the vertical or inclined second direction.

[0050] Furthermore, the transfer member 131 can also be a connecting structure such as a clamping jaw or a suction cup that can facilitate connection to or detachment from the storage rack 6. The transfer driving member 132 can be a driving structure such as a linear motor, a cylinder, or an electric cylinder that can drive the transfer member 131 to reciprocate in the second direction. The transfer driving member 132 can also include a transmission structure composed of a motor and a transmission belt extending along the second direction, as long as it can realize the reciprocating movement of the transfer member 131 in the second direction.

[0051] Continue to refer to Figure 4 、 Figure 5 and Figure 7 As shown, the transfer assembly 13 further includes a first lifting member 1331 and a second lifting member 1332. The first lifting member 1331 and the second lifting member 1332 are correspondingly arranged at the first station 81 and the second station 82. The first lifting member 1331 can rise a set height in the vertical direction, so that the storage rack 6 at the first station 81 is separated from the first conveying assembly 11. The second lifting member 1332 can rise to a position flush with the first lifting member 1331 in the vertical direction.

[0052] Through the setting of the first lifting member 1331, when the storage rack 6 is transferred from the first station 81 to the second station 82, the bottom of the storage rack 6 can be separated from the first conveying assembly 11, avoiding interference between the storage rack 6 and the first conveying assembly 11 and the second conveying assembly 12. After the storage rack 6 moves above the second station 82, through the setting of the second lifting member 1332, the storage rack 6 at the same height transferred from the first station 81 can be received more smoothly. After the second lifting member 1332 receives the storage rack 6, it drives the storage rack 6 to move down until the storage rack 6 lands on the second conveying assembly 12, so that it can be continuously transported by the second conveying assembly 12.

[0053] In some further embodiments, rolling elements 134 are provided on the tops of the first lifting member 1331 and / or the second lifting member 1332. The first lifting member 1331 and / or the second lifting member 1332 are in rolling cooperation with the bottom of the storage rack 6 through the rolling elements 134. Among them, the rolling elements 134 can be structures such as rollers, balls or Mecanum wheels, etc., so as to reduce the friction between the bottom of the storage rack 6 and the first lifting member 1331 and / or the second lifting member 1332 when the transfer member 131 pushes the storage rack 6 on the first lifting member 1331 towards the second lifting member 1332, and can also improve the stability of the storage rack 6 during movement; specifically, when the rolling element 134 is a Mecanum wheel, it can not only provide a reliable and stable supporting force for the bottom of the storage rack 6, but also realize rolling friction with the first lifting member 1331 and / or the second lifting member 1332 when the storage rack 6 moves in the first direction, the second direction or the third direction.

[0054] Continue to refer to Figure 4 As shown, the transfer assembly 13 further includes a transfer track provided between the first lifting member 1331 and the second lifting member 1332. The transfer track extends in the second direction. The transfer track includes a transfer plane 136, and the transfer plane 136 is flush with the first lifting member 1331 after rising by a set height; it should be noted that when the storage rack 6 moves from the first lifting member 1331 to the second lifting member 1332, the storage rack 6 first disengages from the first lifting member 1331, then moves onto the transfer plane 136 of the transfer track, and then moves onto the second lifting member 1332. Specifically, the bottom of the storage rack 6 can be in contact with two or three of the first lifting member 1331, the transfer track, and the second lifting member 1332 at the same time.

[0055] Through the setting of the transfer track, the gap between the first lifting member 1331 and the second lifting member 1332 can be filled, so that the storage rack 6 can always be reliably supported during the process of moving from the first station 81 to the second station 82.

[0056] In some embodiments, the transfer track further includes two groups of first track baffles 1351 arranged in the first direction. The two groups of first track baffles 1351 are spaced apart by a set distance, and the set distance is not less than the length of the storage rack 6 in the first direction. A transfer path for the storage rack 6 to move from the first station 81 to the second station 82 is formed between the two groups of first track baffles 1351. Specifically, the two first track baffles 1351 extend in the second direction, and the two first track baffles 1351 can limit the storage rack 6 in the first direction; further, the transfer path formed between the two first track baffles 1351 can stably limit the storage rack 6, so that the storage rack 6 can move along the set route.

[0057] Further, one of the first track baffles 1351 is located between the first station 81 and the second station 82, and its length is not greater than the length of the gap between the first station 81 and the second station 82 in the second direction. The other first track baffle 1351 extends from the end of the first station 81 away from the second station 82 to the end of the second station 82 away from the first station 81, and its length is equivalent to the total length of the first station 81, the second station 82, and the gap between the first station 81 and the second station 82 in the second direction. That is to say, the longer first track baffle 1351 can limit the storage rack 6 located at the first station 81 and the second station 82 in the first direction.

[0058] In a further embodiment, the transfer track further includes a second track baffle 1352. The second track baffle 1352 extends along the first direction or the third direction. The second track baffle 1352 is disposed on the side of the second station 82 away from the first station 81 and / or the second track baffle 1352 is disposed on the side of the first station 81 away from the second station 82, so as to further improve the stability of the storage rack 6 when it is located at the first station 81 and / or the second station 82, and prevent the storage rack 6 from falling from the first station 81 or the second station 82 along the second direction outside the first conveying assembly 11 or the second conveying assembly 12.

[0059] Specifically, the second track baffle 1352 can be a separate plate-like structure or can be formed by bending one of the first track baffles 1351 by 90 degrees.

[0060] In some further embodiments, the sheet feeding device further includes a position sensor 3 and a lifting mechanism 2 disposed at the feeding station 84. The storage rack 6 includes a bracket for limiting the sheet 7 and a support member 611 for supporting the sheet 7. The support member 611 is configured to lift and lower within the bracket driven by the lifting mechanism 2. The position sensor 3 is disposed above the feeding station 84 and is used to detect whether the uppermost sheet 7 in the storage rack 6 located at the feeding station 84 has risen in place.

[0061] Among them, the position sensor 3 can be a pair of photoelectric sensors. The emitting end and the receiving end are located on the same horizontal plane and are respectively located on both sides of the feeding station 84. When the uppermost sheet 7 rises in place, the uppermost sheet 7 can block the light transmission between the emitting end and the receiving end of the position sensor 3, so that the position sensor 3 detects that the uppermost sheet 7 has moved in place, and the position sensor 3 gives a signal to the lifting mechanism 2 to stop further lifting.

[0062] In some embodiments, the lifting mechanism 2 includes a lifting drive member 21, a telescopic drive member 22 and a lifting member 23. The telescopic drive member 22 is transmission-connected to the lifting drive member 21 and is arranged on the side of the loading station 84. The lifting member 23 is installed at the driving end of the telescopic drive member 22 or the driving end of the lifting drive member 21. The telescopic drive member 22 is used to drive the lifting member 23 to move closer to or away from the storage rack 6. The lifting drive member 21 is used to drive the lifting member 23 to reciprocate in the vertical direction. The lifting member 23 is used to lift the support member 611 located at the loading station 84 upward.

[0063] Specifically, the lifting member 23 can be a plate-shaped structure, so that the film body 7 of the plate-shaped structure can be lifted stably. The lifting drive member 21 and the telescopic drive member 22 can be one or more structures such as a linear motor, a cylinder, and an electric cylinder.

[0064] It should be noted that there is a gap between every two adjacent sheets 7 in the vertical direction that is greater than the thickness of the lifting member 23, so that the lifting member 23 can be inserted between any two adjacent sheets 7. Furthermore, when lifting the sheet 7 upward, the lifting member 23 can be extended to the bottom of the lowest sheet 7, and then moved upward a certain distance each time to allow the top sheet 7 to rise into place and complete the loading. The lifting member 23 can also only lift the top sheet 7 into place each time to complete the loading. The lifting member 23 can also lift two or more sheets 7 each time until all the sheets 7 above the lifting member 23 have completed the loading in turn, and then move downward to the bottom of two or more sheets 7. The specific selection can be made according to the load-bearing capacity of the lifting member 23 and other requirements.

[0065] Continue to refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, the storage rack 6 includes at least two sheet accommodating spaces 61 arranged side by side, and each sheet accommodating space 61 is provided with a support 611 for supporting the sheet 7; the sheet loading device also includes a rotating mechanism 4, which is used to drive the storage rack 6 located at the loading station 84 to rotate horizontally by a predetermined angle to control at least two sheet accommodating spaces 61 to move to the loading position in sequence, wherein the movement of the sheet accommodating space 61 to the loading position means that the projection of the sheet accommodating space 61 in the vertical direction coincides with the projection of the position for taking the sheet, and the sheet 7 in the sheet accommodating space 61 is lifted into place and the loading work can be completed. The setting of the rotating mechanism 4 can enable a storage rack 6 to transport multiple rows of sheets 7 at the same time, thereby significantly improving the loading efficiency of the sheets 7. This loading method can not only improve the loading efficiency, but also control the overall height of the storage rack 6 and improve the stability of the storage rack 6 during transportation.

[0066] In some further embodiments, the rotation mechanism 4 includes a rotation driving member 41 and a lifting driving member 42. The fixed end of the rotation driving member 41 is fixedly connected to the driving end of the lifting driving member 42. The movable end of the rotation driving member 41 abuts against the storage rack 6 located at the loading station 84. The lifting driving member 42 is used to drive the rotation driving member 41 to reciprocate in the vertical direction, and the rotation driving member 41 is used to drive the storage rack 6 to rotate in the horizontal plane. By providing the lifting driving member 42, when driving the storage rack 6 at the loading station 84 to rotate, the storage rack 6 can be separated from the second conveying assembly 12, thereby reducing the interference caused by the second conveying assembly 12 to the rotation of the storage rack 6. Among them, the lifting driving member 42 can lift the storage rack 6 before driving the storage rack 6 to rotate, and then lower the storage rack 6 onto the second conveying assembly 12 before the lifting mechanism 2 lifts the sheet body 7 on the storage rack 6, so as to improve the stability of the storage rack 6 when the lifting mechanism 2 lifts the sheet body 7.

[0067] Specifically, the rotation driving member 41 can be a structure such as a rotary cylinder or a motor, and the lifting driving member 42 can be a structure such as a linear motor, a cylinder or an electric cylinder.

[0068] Continue to refer to Figure 1 、 Figure 4 and Figure 5 As shown, the sheet loading device further includes a blocking mechanism 5. There is a third station 83 between the feeding end and the first station 81. The blocking mechanism 5 is provided at at least one of the first station 81, the second station 82, the third station 83 and the loading station 84. The blocking mechanism 5 can be lifted and lowered in the vertical direction to block and limit the storage rack 6 above. Among them, the third station 83 can be a position opposite to the loading station 84 in the second direction, that is, the position where the storage rack 6 moves a size of itself in the second direction along the first station 81. Limiting the storage rack 6 at the third station 83 can prevent the storage rack 6 that has not been transported from the first station 81 to the second station 82 from colliding with the storage rack 6 moving from the third station 83 to the first station 81. It should be understood that there can be at most one storage rack 6 between the first station 81 and the second station 82. That is to say, before the storage rack at the second station 82 is transported to the loading station 84, no storage rack 6 will be transported from the third station 83 to the first station 81, and at this time the first station 81 is an empty position.

[0069] Continue to refer to Figure 3As shown, an outer retaining ring 62 is provided on the outer circumference of the storage rack 6. Among them, the outer retaining ring 62 of the storage rack 6 located at the first station 81 can abut against the outer retaining ring 62 of the storage rack 6 located at the third station 83, and the outer retaining ring 62 of the storage rack 6 located at the second station 82 can abut against the outer retaining ring 62 of the storage rack 6 located at the loading station 84. Thus, it can be ensured that the storage rack 6 can achieve the limit of two adjacent stations through the outer retaining ring 62. It should be understood that when the storage rack 6 is located at the loading station 84, its outer retaining ring 62 is coaxially arranged with the output shaft of the rotary driving member 41. Thus, it can be ensured that when the storage rack 6 located at the loading station 84 rotates, it will not rub against the surrounding structures, affecting the stability of the storage rack 6 during rotation.

[0070] Specifically, the blocking mechanism 5 may include structures such as a linear motor, an electric cylinder, a cylinder, etc. that can be telescoped in the vertical direction; through the setting of the blocking mechanism 5, by raising the blocking mechanism 5, the blocking mechanism 5 can block and limit the storage rack 6 above it or moving towards it, preventing it from continuing to move and colliding with the storage rack 6 that has passed through the blocking mechanism 5.
