Description

Technical Field

[0001] This utility model is an anti-misalignment positioning structure for battery cell stacking, belonging to the field of battery cell assembly. Background Technology

[0002] Sodium iron phosphate (SOF) cells, as a core component of a new type of sodium-ion battery, have shown broad application prospects in energy storage, low-speed electric vehicles, and other fields due to their advantages such as abundant raw materials, low cost, and high safety. The stacking process is a crucial step in the manufacturing of SOF cells. Using vertically arranged telescopic cylinders, a carrier plate equipped with vacuum suction cups moves vertically up and down. The vacuum suction cups firmly adhere to the cells using negative pressure, achieving stable gripping. Subsequently, a rodless cylinder is activated, moving the carrier plate horizontally to precisely transfer the cells adsorbed on the vacuum suction cups between two processes, finally placing them stably on a moving base. The moving base is equipped with multiple sets of clamps that limit the cells from all sides, ensuring that the cells do not shift or tip over during movement and guaranteeing the neatness of the stacking process. Next, an electric push rod begins to operate, driving the moving base to move back and forth between two carrier plates to receive cells from different carrier plates and complete the stacking. When the stacked battery cells reach the center area between the two carriers along with the moving base, the battery cell transfer module will activate and transfer the entire stack of battery cells to the next process for subsequent processing.

[0003] However, if the electric push rod fails to extend or retract completely during this process, the actual stopping position of the moving base will deviate from the preset center area. This will cause the stacked battery cells on the moving base to not be accurately positioned directly below the battery cell transfer module's picking area, potentially leading to misalignment during the transfer module's gripping process. This can range from failing to pick up the battery cells successfully to causing them to fall, scatter, and ultimately resulting in misaligned battery cell transfer, affecting the continuity and stability of the entire production process. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-misalignment positioning structure for battery cell stacking, so as to solve the problems mentioned in the background technology. This utility model prevents the battery cell from being placed on the moving base when the moving base has not moved to the designated position.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a misalignment prevention and positioning structure for battery cell stacking, comprising:

[0006] Base plate;

[0007] A movable base is set on the upper side of the base plate. The movable base is connected to the base plate through an adjusting component. Four pads for supporting the battery cells are evenly installed on the upper surface of the movable base. The cross-section of the pads is "I" shaped. Multiple clamps for limiting the position of the battery cells are evenly provided on the outer periphery of the pads. The clamps are connected to the movable base by screws.

[0008] There are two horizontal plates, which are symmetrically installed on the upper surface of the base plate. Horizontally arranged rodless cylinders are installed on the opposite surfaces of the two horizontal plates.

[0009] A telescopic cylinder is installed at the movable end of a rodless cylinder. A carrier plate is installed at the movable end of the telescopic cylinder. Multiple vacuum suction cups for adsorbing battery cells and connecting to the vacuum pipeline system are evenly installed on the lower surface of the carrier plate.

[0010] The snap-fit ​​part is installed at the middle of the lower surface of the carrier plate. Both ends of the snap-fit ​​part are snapped with snap-fit ​​seats, and the snap-fit ​​seats are installed on the upper surface of the movable base by screws.

[0011] Furthermore, the adjusting member includes:

[0012] The support has two parts, which are symmetrically installed on the lower surface of the movable base. The lower end of the support is connected to the base plate by screws.

[0013] The guide rail is mounted on the upper surface of the support;

[0014] A slide block is slidably mounted on a guide rail, and the slide block is connected to a movable base by screws;

[0015] An electric push rod is disposed between two supports. The cylinder end of the electric push rod is connected to one support, and the movable end of the electric push rod is connected to a movable seat. The electric push rod is arranged along the length of the support, and the support and the cross plate are arranged perpendicular to each other.

[0016] Furthermore, the movable end of the electric push rod is equipped with a connecting lug, which is installed on the lower surface of the movable seat by screws.

[0017] Furthermore, two symmetrically arranged limiting seats are installed on the side of one of the supports away from the electric push rod. The limiting seats are L-shaped, and long screws are threaded to the opposite surfaces of the two limiting seats. A blocking plate is provided between the two long screws, and the blocking plate is installed on the lower surface of the movable seat.

[0018] Furthermore, each of the two supports has multiple rectangular openings on its opposite surfaces, and these rectangular openings are arranged along the length of the support.

[0019] Furthermore, a connecting frame is installed at the cylinder end of the telescopic cylinder, and the connecting frame is connected to the movable end of the rodless cylinder by screws.

[0020] Furthermore, two support plates are installed on the back of each of the two horizontal plates, and the lower ends of the support plates are connected and fixed to the base plate by screws.

[0021] Furthermore, the upper surface of the carrier plate is uniformly provided with multiple through holes, the upper end of the vacuum suction cup passes through the through holes, and the upper end of the vacuum suction cup is threaded with two nuts for limiting the relative position of the vacuum suction cup and the carrier plate.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. The locking part on the lower surface of the carrier plate forms a precise docking structure with the locking seat on the moving base. The locking part can only engage with the locking seat when the moving base is fully in the preset position, at which point the vacuum suction cup will release the battery cell. If the electric push rod does not extend or retract to the full extent, causing the moving base to shift, the locking part and the locking seat will not match, and the battery cell will not be lowered into the moving base, thus avoiding transfer errors caused by positional deviations of the battery cell from the source.

[0024] 2. The "I"-shaped pad on the moving base provides stable support for the battery cells. Multiple clamping blocks around its perimeter form a surrounding limit on the battery cells, working in conjunction with snap-fit ​​positioning to ensure that the battery cells maintain a neat posture during stacking and movement, reducing displacement caused by slight shaking. Two carrier plates correspond to different processes. Through the coordinated action of rodless cylinders and telescopic cylinders, battery cells can be alternately fed to the moving base. Driven by an electric push rod, the moving base receives and stacks the cells in an orderly manner. The limiting effect of the clamping blocks ensures that each layer of battery cells is aligned, improving stacking accuracy.

[0025] 3. The long screw on the limit seat can be adjusted by rotating to change its extension length. Together with the baffle plate under the moving seat, it can precisely limit the maximum travel of the moving seat and avoid overtravel problems caused by overload of the electric push rod.

[0039] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0040] Example:

[0041] Please see Figures 1-4 This utility model provides a technical solution: a positioning structure for preventing misalignment during battery cell stacking, including a base plate 1, a movable seat 2 disposed on the upper side of the base plate 1, two supports 21 symmetrically mounted on the lower surface of the movable seat 2, the lower ends of the supports 21 connected to the base plate 1 by screws, multiple rectangular openings on the opposite surfaces of the two supports 21 arranged along the length of the supports 21, a guide rail 23 mounted on the upper surface of the supports 21, a slide 25 slidably mounted on the guide rail 23, the slide 25 connected to the movable seat 2 by screws, and an electric push rod 22. The electric push rod 22 is positioned between two supports 21. The cylinder end of the electric push rod 22 is connected to one of the supports 21. The movable end of the electric push rod 22 is equipped with a connecting ear 24. The connecting ear 24 is installed on the lower surface of the movable seat 2 by screws. The connecting ear 24 connects the movable end of the electric push rod 22 to the movable seat 2. The electric push rod 22 is arranged along the length of the support 21. The support 21 and the cross plate 4 are arranged perpendicular to each other. During the extension and retraction of the electric push rod 22, it drives the movable seat 2 to move. The movable seat 2 drives the slider 25 to move along the guide rail 23, thereby limiting the movement trajectory of the movable seat 2.

[0042] See Figures 1-4Four pads 27 for supporting the battery cell 5 are evenly installed on the upper surface of the movable base 2. The cross-section of the pads 27 is "I" shaped. Multiple clamps 26 for limiting the position of the battery cell 5 are evenly provided on the outer periphery of the pads 27. The clamps 26 are connected to the movable base 2 by screws. There are two horizontal plates 4, which are symmetrically installed on the upper surface of the base plate 1. Two support plates 42 are installed on the back of each of the two horizontal plates 4. The lower end of the support plates 42 is connected and fixed to the base plate 1 by screws. The support plates 42 serve to connect the base plate 1 and the horizontal plates 4.

[0043] Two horizontally arranged rodless cylinders 41 are installed on opposite sides of the two horizontal plates 4. A connecting frame 32 is installed on the cylinder end of the telescopic cylinder 3. The connecting frame 32 is connected to the movable end of the rodless cylinder 41 by screws. A carrier plate 31 is installed on the movable end of the telescopic cylinder 3. Multiple vacuum suction cups 33 for adsorbing the battery cell 5 and connecting to the vacuum pipeline system are evenly installed on the lower surface of the carrier plate 31. Multiple through holes are evenly opened on the upper surface of the carrier plate 31. The upper end of the vacuum suction cup 33 passes through the through holes. Two nuts for limiting the relative position of the vacuum suction cup 33 and the carrier plate 31 are threaded to the upper end of the vacuum suction cup 33. Four "I"-shaped pads 27 installed on the upper surface of the moving base 2 can provide a stable support base for the battery cell 5 and prevent the battery cell 5 from tilting when placed.

[0044] Multiple clamping blocks 26 evenly distributed around the periphery of the pad 27 form a surrounding limit around the battery cell 5. Together with the snap-fit ​​part 6 and snap-fit ​​seat 61 between the carrier plate 31 and the moving seat 2, they can ensure that the battery cell 5 maintains a neat arrangement during the stacking process and the transfer process driven by the moving seat 2, effectively reducing the positional deviation caused by slight vibration of the equipment or the inertia of movement.

[0045] Two carrier plates 31 correspond to different process steps. Under the coordinated action of the horizontal drive of the rodless cylinder 41 and the vertical extension of the telescopic cylinder 3, the gripped battery cells 5 can be alternately transferred to the top of the moving seat 2. The moving seat 2, driven by the electric push rod 22, moves smoothly along the guide rail 23 and receives the battery cells 5 in an orderly manner, gradually completing the stacking operation. During this process, the clamping block 26 limits the positioning of each layer of battery cells 5, ensuring that each layer of battery cells 5 is precisely aligned, significantly improving the overall accuracy of the battery cell stacking.

[0046] See Figures 1-4The locking part 6 is installed at the center of the lower surface of the carrier plate 31. Both ends of the locking part 6 are fitted with locking seats 61, which are screwed onto the upper surface of the movable seat 2. The locking part 6 on the lower surface of the carrier plate 31 and the locking seats 61 on the movable seat 2 form a precise docking structure with a strict positional correspondence. Only when the movable seat 2 is fully driven to the preset position by the electric push rod 22 can the locking part 6 successfully engage with the locking seat 61. At this time, the vacuum suction cup 33 will initiate the release procedure, placing the adsorbed battery cell 5 onto the movable seat 2. Conversely, if the electric push rod 22 fails to extend or retract completely, causing the movable seat 2 to deviate from the preset position, the positions of the locking part 6 and the locking seat 61 will be misaligned, preventing effective docking. In this case, the vacuum suction cup 33 will not release the battery cell 5, and the battery cell 5 will not be lowered onto the movable seat 2, thus fundamentally eliminating the transfer error caused by the inaccurate position of the battery cell 5.

[0047] Working principle:

[0048] The locking base 61 has a built-in pressure sensor. When the movable base 2 reaches the preset position precisely, the locking part 6 and the locking base 61 are fully engaged. The pressure sensor is squeezed and triggers a conduction signal. This signal is transmitted to the control unit of the vacuum pipeline system, such as the solenoid valve controller. Vacuum system on / off control: After receiving the conduction signal, the control unit instructs the solenoid valve in the vacuum pipeline to switch to the "venting" state, cuts off the negative pressure connection between the vacuum generator and the vacuum suction cup 33, and at the same time introduces a small amount of compressed air into the vacuum suction cup 33, so that the negative pressure in the vacuum suction cup 33 disappears, and the battery cell is stably placed on the movable base 2 under the action of gravity.

[0049] Signal interruption during misalignment: If the position of the movable seat 2 is offset, the locking part 6 and the locking seat 61 cannot engage, the pressure sensor is not triggered, and the control unit always receives a "disconnect signal". At this time, the solenoid valve remains in the "vacuum" state, and the vacuum suction cup 33 continuously maintains negative pressure, firmly adsorbing the battery cell. Even if the operator accidentally operates the release button, the vacuum system will not perform the release action because the mechanical triggering condition is not met, ensuring that the battery cell is not mistakenly lowered.

[0050] See Figure 1 and Figure 4On the side of a support 21 facing away from the electric push rod 22, two symmetrically arranged limiting seats 7 are installed. The limiting seats 7 have an L-shaped structure, and each of the two limiting seats 7 has a long screw 71 threadedly connected to its opposite surface. A blocking plate 72 is provided between the two long screws 71 and is installed on the lower surface of the movable seat 2. The long screws 71 on the limiting seats 7 can be rotated to adjust their extension length. When the movable seat 2 moves under the drive of the electric push rod 22, the blocking plate 72 at its bottom will cooperate with the long screws 71—the extension length of the long screws 71 determines the farthest position that the blocking plate 72 can reach, thereby precisely limiting the maximum travel of the movable seat 2. This design can effectively prevent the movable seat 2 from exceeding the preset range due to overload of the electric push rod 22, ensuring that the movable seat 2 always moves smoothly within the set safe travel range.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
