Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery production, in particular to a 1E-level battery pole group slot-entering device. Background Art

[0002] Lead-acid batteries consist of positive and negative plates, separators, plastic components, and related lead parts. Both positive and negative plates are typically pasted. This process involves adding sulfuric acid, water, and additives to fine lead powder with an average particle size of 3-5 μm. The paste is then applied to the lead alloy grid surface via extrusion. The plate active material produced in this manner has a large surface area and excellent electrolyte absorption, ensuring rapid battery charging and discharging. Electrical equipment (including batteries) used in critical facilities such as nuclear power plants must meet IEC 60783-1E standards. Such equipment must be highly reliable and able to continue operating for a sufficient period after an accident to ensure safe reactor shutdown and subsequent operation. This creates higher quality and safety requirements for 1E-rated batteries. Currently, the process for inserting lead-acid battery cell clusters into the battery cell typically involves a cylinder-driven ram, which presses vertically against the positive and negative busbars of the cell cluster, pressing the cell cluster to the bottom of the cell. In current production, when the existing slot-entering mechanism is inserting the electrode group into the slot, the edge of the partition is likely to interfere with the edge of the battery slot, and the coated paper of the side plate is scratched and rolled up, accumulating at the position of the through-wall welding hole, which is likely to cause lead explosion in the subsequent through-wall welding process. Utility Model Content

[0003] Technical problems to be solved by utility models

[0004] In response to the technical problem that the edges of the partitions are easily interfered with the edges of the battery slot during the insertion of the existing lead-acid battery pole groups into the battery slot, the utility model provides a 1E-level battery pole group insertion device, which can compress the partition paper at the bottom of the partial pole column to avoid the interference between the edges of the partition and the edges of the battery slot.

[0005] Technical Solution

[0006] In order to solve the above problems, the technical solution provided by the present invention is as follows:

[0007] A 1E-level battery pole group slotting device includes a downward pressing assembly, including a downward pressing drive cylinder and multiple groups of pressure hammers, the pressure hammers are distributed according to the groups of battery pole groups and fixed to a fixed plate, the fixed plate is connected to the output end of the downward pressing drive cylinder, and a blocking assembly is provided between the pressure hammers of adjacent groups; the blocking assembly includes a wedge block and a flat pulling drive cylinder, the wedge block is rotatably connected to the downward pressing assembly through a connecting pin, the tip of the wedge block faces the group gap of the battery pole group, the output end of the flat pulling drive cylinder is connected to the wedge block to form a lever structure with the connecting pin as the fulcrum.

[0008] The downward pressure assembly includes a downward pressure drive cylinder and multiple groups of pressure hammers. These hammers are arranged according to the different groups of battery cell clusters and fixed to a plate (fixed plate). The fixed plate is connected to the output of the downward pressure drive cylinder, which means that when the cylinder is actuated, the entire fixed plate will drive all the pressure hammers to move together. Blocking components are provided between adjacent pressure hammers to prevent interference between the pressure hammers and ensure that each pressure hammer can act independently on its corresponding battery cell cluster. The downward pressure drive cylinder is used to drive the pressure hammers, which are used to press down the battery cell cluster. The wedge block is used to press down the separator paper to prevent it from rolling up and causing subsequent defects. The separator paper is located in the group gaps of the battery cell cluster. The horizontal pull drive cylinder and connecting pin are used to adjust the angle of the wedge block so that the tip of the wedge block faces the group gap of the battery cell cluster to prevent it from being inserted. The lever structure formed facilitates the control of the horizontal pull drive cylinder.

[0009] Optionally, the output end of the horizontal pull drive cylinder is connected to the same end of the wedge block as is connected to an anti-loosening spring, and the other end of the anti-loosening spring is connected to a spring fixing plate, and the spring fixing plate is fixed to the fixing plate.

[0010] One end of the anti-loosening spring is connected to the same end of the wedge block (i.e., the side connected to the pull-drive cylinder), while the other end is connected to a spring retaining plate. This spring retaining plate is fixed to the integral retaining plate, creating a stable structure that allows the wedge block to move smoothly when subjected to the pull-drive cylinder's force and return to its original position under the spring's force when no force is applied. In the absence of external forces, the anti-loosening spring ensures that the wedge block remains in its set position, preventing displacement caused by mechanical vibration or other external factors. When the pull-drive cylinder pulls the wedge block, the anti-loosening spring is compressed. Once the cylinder's force is removed, the spring pushes the wedge block back to its original position. The wedge block can be precisely inserted into the gap between the battery cell groups and quickly reset after the operation is completed, avoiding interference with other components. The presence of the anti-loosening spring improves the system's response speed and repeatability, contributing to improved production efficiency and quality.

[0011] Optionally, a limiting block is fixedly connected to the lower side of the fixed plate, and the limiting block cooperates with the upper end of the wedge block to limit the position, and the limiting block is located on the outer side of the wedge block.

[0012] The stopper is fixed below the fixed plate and interacts with the upper end of the wedge block to act as a limiter. Specifically, its location outside the wedge block means that when the wedge block moves under the action of the horizontal pull drive cylinder, the stopper acts as a physical boundary, limiting the maximum range of movement of the wedge block. The stopper effectively prevents mechanical damage to the wedge block due to operational errors or control system failures, thereby improving the safety and reliability of the entire system.

[0013] Optionally, a buffer pad is provided on the contact surface between the limiting block and the wedge block.

[0014] The cushion absorbs the impact of the wedge block contacting the stopper, reducing direct collisions between machine parts, thereby reducing wear rates and the risk of equipment damage. By reducing hard contact, the cushion also reduces noise levels and improves the working environment.

[0015] Optionally, the pressing hammer is facing the busbar of the battery pole group.

[0016] The position of the pressure hammer is aligned with the busbar in the battery group, ensuring that when the group is installed into the battery housing (battery slot), each pressure hammer can accurately apply force to the corresponding busbar, thereby achieving precise positioning and assembly.

[0017] Optionally, the group gaps of the battery pole group are gaps of the polar columns, and the length of the wedge block is greater than the height of the polar columns.

[0018] Make sure the separator paper is compressed to the bottom of the polarizer post. If it is too short, it will not be pressed to the bottom.

[0019] Optionally, the width of the tip of the wedge block is less than half the width of the group gap of the battery pole group.

[0020] The tip of the wedge is designed to be narrower than half the width of the gap between the battery cell groups. This means that the narrowest part (the tip) of the wedge can easily pass through the gap without getting stuck or causing resistance. This design ensures that when the wedge is inserted into the gap, it can minimize the contact area with both sides of the gap, thereby reducing the squeezing or scratching of the battery cell groups.

[0021] Optionally, the connecting pin is located directly above the group gap of the battery pole group.

[0022] When the connecting pin is positioned directly above the gap, the wedge can move in a straight line along the gap during insertion, reducing friction and contact between the wedge and both sides of the gap, thereby making the operation easier. This design helps prevent the wedge from deviating from its target position during insertion, ensuring that it can smoothly enter the gap and perform its intended function. The positioning of the connecting pin ensures a more certain path for the wedge during operation, reducing uncertainty caused by positional deviations and improving the operational accuracy of the entire device. Because the wedge can move accurately along the gap, uncertainty during operation is reduced and the reliability of the device is improved.

[0030] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0031] Example

[0032] Combined with attachment Figure 1-3 A 1E-level battery pole group slotting device includes a pressing component and a barrier component, and the pressing component and the barrier component are both fixed on the lower plate surface of the fixed plate 2.

[0033] The pressing assembly includes a pressing drive cylinder 1 and multiple groups of pressing hammers 3. In this embodiment, there are three groups of pressing hammers 3, one group is a pair, corresponding to the two busbars 5 of the battery group. The pressing hammers 3 are directly opposite to the busbars 5 of the battery group. The outside of the battery group is a battery slot 4, which is combined with the attached Figure 1 A pole group separator 6 is provided between the battery pole groups parallel to the viewing plane.

[0034] The pressure hammers 3 are distributed according to the groups of battery poles and fixed to the fixed plate 2. The fixed plate 2 is connected to the output end of the downward driving cylinder 1. A barrier component is provided between adjacent groups of pressure hammers 3.

[0035] The blocking assembly includes a wedge block 9 and a flat-pull drive cylinder 12. The wedge block 9 is rotatably connected to the pressing assembly via a connecting pin 8. The tip of the wedge block 9 faces the group gap of the battery pole group. The output end of the flat-pull drive cylinder 12 is connected to the wedge block 9 to form a lever structure with the connecting pin 8 as the fulcrum. The group gap of the battery pole group is the gap of the eccentric pole column 7. The length of the wedge block 9 is greater than the height of the eccentric pole column 7. The width of the tip of the wedge block 9 is less than half the width of the group gap of the battery pole group. The connecting pin 8 is located directly above the group gap of the battery pole group. Since the position of the connecting pin 8 is fixed and aligned with the gap, it is easier to check and correct the position of the wedge block 9 when maintaining or adjusting the device, ensuring that it is always in optimal working condition. By ensuring that the connecting pin 8 is located directly above the gap, the interference of the wedge block 9 with other components during the insertion and withdrawal process can be minimized, thereby avoiding problems that may be caused by mechanical interference. This effectively avoids interference between the edges of the separator and the battery container 4, and reduces the accumulation of coated paper, thereby improving the quality and efficiency of battery assembly. By precisely controlling the movements of the hammer 3 and the horizontal pull drive cylinder 12, the battery group can be correctly installed in place, while also reducing potential problems in subsequent processes.

[0036] Observe the fit of the wedge block 9 in the gap between the offset column 7 and the battery slot 4. If the fit is not good, start the horizontal pull drive cylinder 12 to extend or retract it, and adjust the deflection angle of the wedge block 9 to keep it fit with the group gap.

[0037] The output end of the pull-action drive cylinder 12 is connected to the same end of the wedge block 9 as the anti-loosening spring 10. The other end of the anti-loosening spring 10 is connected to a spring retaining plate 112, which is affixed to the fixed plate 2. The anti-loosening spring 10 is in a tensioned state, with the anti-loosening spring 10 and spring retaining plate 112 positioned outside the wedge block 9. During commissioning, the pull-action drive cylinder 12 also extends outward, causing the wedge block 9 to tilt at a certain angle. During this process, the anti-loosening spring 10 exerts a reverse tensile force, preventing the wedge block 9 from loosening.

[0038] A limit block 13 is fixed to the bottom of the fixed plate 2. The limit block 13 cooperates with the upper end of the wedge block 9 to limit the position. The limit block 13 is located outside the wedge block 9. In combination with the anti-loosening spring 10 mentioned above, the limit block 13 and the anti-loosening spring 10 work together to ensure that the wedge block 9 can not only accurately reach the target position when performing a task, but also smoothly return to the track after the task is completed, without getting stuck or falling off the track.

[0039] The contact surface between the stopper 13 and the wedge block 9 is provided with a cushion. This cushion is typically made of an elastic material such as rubber or polyurethane, which has excellent shock absorption and wear resistance. Depending on the operating environment and load requirements, cushion materials of varying hardness and thickness can be selected.

[0040] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
