Abstract

The application discloses a battery shell cover sealing ring embedding structure and particularly relates to the technical field of air compressors. The sealing ring is prepositioned by the anti-deviation device, and the sealing ring is finally compressed after the battery upper cover is lowered, so that the position constraint of the sealing ring is formed before the sealing ring is compressed by the battery upper cover. The consistency and stability of the subsequent shell cover sealing are improved. The sealing ring is carried by the moving frame to pass through the space between the battery upper cover and the battery shell laterally, so that the sealing ring transfer path and the clamping position of the battery upper cover avoid each other. Different specifications of the sealing rings are stored respectively. The moving frame is moved to the corresponding material placing box according to the specification of the current battery shell to take the material. When the battery shells of different specifications are switched, the material placing box does not need to be frequently emptied and replaced with a whole batch of sealing rings, the preparation time required for specification switching is shortened, and the adaptability of the embedding structure to different specifications of the battery shells is improved.

Description

Technical Field

[0001] This invention relates to the field of battery case cover sealing technology, specifically to a battery case cover sealing ring embedding structure. Background Technology

[0002] With the rapid development of new energy vehicles and energy storage equipment, the number of power batteries and energy storage batteries used is constantly increasing. The battery casing is usually used to house the battery cells, connecting components, and battery management components. To prevent external moisture, dust, and other impurities from entering the battery casing, a sealing ring is usually installed between the battery casing and the battery cover. The sealing ring is compressed and deformed by bolt tightening, pressing, or other methods to form a sealed structure.

[0003] In the current assembly process of battery casing and battery cover, the sealing ring is usually made of flexible material. After being transported and placed on the surface of the battery casing, it is prone to shrinkage, displacement, or local warping due to its own elasticity. When the battery cover is lowered and pressed in, it may further move due to contact friction, making it difficult for the sealing ring to be stably maintained in the predetermined sealing position, affecting the sealing consistency between the battery casing and the battery cover. At the same time, the feeding, transportation, and clamping and pressing of the sealing ring and the battery cover usually need to be carried out in steps. The movement interference between the sealing ring transportation mechanism and the battery cover is prone to occur, requiring multiple repositioning or repositioning of the battery cover, which affects the assembly efficiency. In addition, the sealing ring size varies for different battery casing specifications. When switching product specifications, it is necessary to frequently change the feeding components or rearrange the sealing ring, resulting in cumbersome changeover operations and limited adaptability of the assembly structure to different product specifications. Summary of the Invention

[0004] The purpose of this invention is to provide a battery casing cover sealing ring embedding structure to solve the problems mentioned in the background art.

[0005] The main technical problem solved by this invention is: After the sealing ring is transported and placed on the surface of the battery case, it is prone to shrinkage, displacement or local warping due to its own elasticity. When the battery cover is lowered and pressed, it may also move further due to contact friction. The sealing ring is difficult to keep stably in the predetermined sealing position, which affects the sealing consistency between the battery case and the battery cover.

[0006] This invention can be achieved through the following technical solutions: A battery casing cover sealing ring embedding structure includes a substrate. A limiting unit for defining the battery casing is provided in the middle of the upper surface of the substrate. Material boxes for supporting sealing rings of corresponding specifications are provided on both sides of the limiting unit. A lifting plate for pushing the sealing ring of corresponding specifications to rise is provided in each material box. Both sides of the substrate are equipped with synchronously moving linear guides. Each linear guide has an L-shaped connecting frame mounted on its slider. The ends of the two connecting frames are connected to the same moving frame. The moving frame is equipped with an adsorption unit that fixes the sealing ring inside the material box. Above the limiting unit, there is a clamping unit for fixing the battery cover. There is an initial height difference between the clamping unit and the limiting unit for the moving frame to slide through. The upper surface of the battery casing is equipped with an anti-deviation component that works in conjunction with the sealing ring.

[0007] A further technical improvement of the present invention is that: the anti-deviation component includes a rectangular block disposed on the surface of the battery case and inserted into the sealing ring, and positioning posts for positioning the sealing ring are provided at the outer and inner edges of the rectangular block; The inner cavity of the battery cover has a limiting protrusion that works in conjunction with the limiting groove on the sealing ring.

[0008] A further technical improvement of the present invention is that: the limiting unit includes a fixed side plate that abuts against one side of the battery case, and movable side plates that are close to or far apart from each other are slidably installed at both ends of the inner wall of the fixed side plate; An opening is provided on the side of the substrate away from the fixed side plate. A slot is provided inside the opening. A sliding lifting component that abuts against the other side of the battery case is installed inside the slot. A through groove is provided on the upper surface of the slot that communicates with the opening.

[0009] A further technical improvement of the present invention is that: the sliding lifting component includes a ramp at the bottom of the slotted inner cavity, a limiting frame that slides along the other side of the battery case is provided at the top of the slotted inner cavity, a clamping plate is installed inside the limiting frame and is limited thereto, a spring is sleeved on the outside of the clamping plate that extends into the limiting frame, and an abutment part that contacts the ramp is provided at the bottom of the clamping plate, and the top surface of the clamping plate is flush with the through groove.

[0010] A further technical improvement of the present invention is that a pushing cylinder is installed on one side of the inner cavity of the slot, and the size of the slot is larger than the size of the through slot, and the pushing end of the pushing cylinder is fixed to one side of the limiting frame; The top surface of the slotted inner cavity is provided with a sliding groove, which slides in a limiting frame.

[0011] A further technical improvement of the present invention is that the adsorption unit includes a lifting plate that is lifted and installed at the top of the inner cavity of the movable frame, and an adsorption plate for fixed-point adsorption of several points on the sealing ring is installed on the bottom surface of the lifting plate.

[0012] A further technical improvement of the present invention is that: the clamping unit includes a U-shaped support frame, a mounting base is fixedly installed in the middle of the bottom surface of the support frame, and two driven bevel gears driven by the driving bevel gear are rotatably installed inside the mounting base. A transmission screw is fixed at the end of each driven bevel gear, and the end of the transmission screw is rotatably arranged with the corresponding side of the support frame. Each drive screw has a threaded clamping component inside to hold the battery cover.

[0013] A further technical improvement of the present invention is that: a sliding rod is installed inside the support frame, the clamping member includes a limiting member, the bottom surface of the limiting member is connected to a clamping cylinder, and the limiting member is slidably arranged with the sliding rod, and the two driving ends of the clamping cylinder are respectively connected to clamping blocks that clamp the edge of the battery cover.

[0014] A further technical improvement of the present invention is that a guide groove is provided on the upper surface edge of the substrate and on the side adjacent to the linear guide rail, and the guide groove is slidably disposed with the moving frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The sealing ring is pre-positioned by the anti-deviation component, and the sealing ring is finally pressed together after the battery cover is lowered. This ensures that the sealing ring is positionally constrained before being pressed by the battery cover, improving the consistency and stability of the subsequent cover sealing. The moving frame carries the sealing ring laterally through the space between the battery cover and the battery case without having to remove the battery cover from the assembly area first. This allows the sealing ring transport path to avoid the clamping position of the battery cover. By setting material boxes on both sides of the limiting unit to hold the sealing rings of the corresponding specifications, sealing rings of different specifications can be stored separately. The moving frame moves to the corresponding material box according to the current battery case specification to retrieve the material. When switching between different battery case specifications, it is not necessary to frequently empty the material box and replace the entire batch of sealing rings, shortening the preparation time required for specification switching and improving the adaptability of the mounting structure to different battery case specifications. 2. By setting a limiting unit and a sliding lifting component, the battery case slides in through the opening, pushing the battery case close to the fixed side plate, so that the battery case completes the position correction with the fixed side plate as the positioning reference. During the movement of the limiting frame, its top is guided and limited by the slide groove, so that the limiting frame slides stably in the set direction. As the abutting part gradually moves from the low position of the slope to the high position, the slope generates an upward component force on the abutting part, so that the clamping plate gradually moves upward relative to the limiting frame. At the same time, the spring sleeved on the outside of the clamping plate is compressed. The fixed side plate and the clamping plate limit the battery case from opposite sides, and the two movable side plates limit it from the other two sides, so that the battery case forms a four-sided positioning state to adapt to battery cases of different specifications. 3. By setting up a clamping unit, two driven bevel gears driven by a driving bevel gear are set inside the mounting base. Two transmission screws drive the corresponding clamping parts to move closer or further away synchronously. This allows the clamping unit to change the distance between the two clamping parts according to the size of different battery cover sizes. This makes the same clamping unit applicable to battery covers of various sizes, reducing the need to replace the entire clamping fixture when changing battery cover sizes. A clamping cylinder drives two clamping blocks to clamp the corresponding edges of the battery cover in opposite directions. This allows the battery cover edges to be acted on from both sides, reducing the problem of the battery cover shifting easily when using a single-sided pushing clamp. Furthermore, the clamping space between the two clamping blocks can form a certain clamping effect on the edges of the battery cover, improving the stability of the battery cover during lifting and lowering.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0020] Please see Figures 1-6As shown, the present invention provides a battery case cover sealing ring embedding structure, including a substrate 1. A limiting unit for limiting the battery case is provided in the middle of the upper surface of the substrate 1. Material boxes 22 for carrying sealing rings of corresponding specifications are provided on both sides of the limiting unit. Each material box 22 is provided with a lifting plate 23 for pushing the sealing ring of corresponding specifications to move upward. Both sides of the substrate 1 are equipped with synchronously moving linear guide rails 2. Each linear guide rail 2 has an L-shaped connecting frame 27 installed on its slider. The ends of the two connecting frames 27 are connected to the same moving frame 5. The moving frame 5 is equipped with an adsorption unit that is fixed to the sealing ring inside the material box 22. Above the limiting unit, there is a clamping unit for fixing the battery cover. There is an initial height difference between the clamping unit and the limiting unit for the sliding frame 5 to pass through. The upper surface of the battery casing is equipped with an anti-deviation component that works in conjunction with the sealing ring.

[0021] In use, the battery case to be assembled is first placed in the limiting unit on the upper surface of the substrate 1. The limiting unit limits the position of the battery case, so that the sealing ring installation area on the upper surface of the battery case is in the preset assembly position. At the same time, the sealing rings that match the current battery case specifications are pre-stacked in the corresponding material box 22, and the sealing rings are centrally supported by the material box 22. As the upper sealing rings are removed one by one, the lifting plate 23 moves upward in the material box 22, lifting the remaining sealing rings as a whole, so that the uppermost sealing ring is always kept at the set height that is convenient for the adsorption unit to pick up the material, reducing the situation where the adsorption unit needs to constantly change the material picking stroke due to the gradual decrease of the number of sealing rings in the material box 22.

[0022] After the battery case is positioned, the linear guide rails 2 on both sides of the substrate 1 move synchronously. The two linear guide rails 2 drive the moving frame 5 to move along the substrate 1 through the connecting frame 27. During the movement, the moving frame 5 is supported and guided by both sides, which reduces the deviation caused by the force on one side of the moving frame 5, so that the adsorption unit set inside the moving frame 5 can move back and forth between the material box 22 and the battery case relatively stably.

[0023] When the moving frame 5 moves above the storage box 22 containing the current specification sealing ring, the adsorption unit moves downward relative to the moving frame 5 and contacts the uppermost sealing ring in the storage box 22. The sealing ring is fixed in a multi-point surface manner through adsorption. After adsorption is completed, the adsorption unit returns to its original position, causing the adsorbed sealing ring to detach from the storage box 22. The lifting plate 23 then continues to push the remaining sealing rings in the storage box 22 upward, so that the next sealing ring is replenished to the preset material picking height for the next installation operation.

[0024] After the sealing ring is fixed by the adsorption unit, the linear guide rails 2 on both sides continue to synchronously drive the moving frame 5 to move towards the direction of the limiting unit. At this time, the battery cover is fixed by the clamping unit above the limiting unit and held above the battery case. Since there is an initial height difference between the clamping unit and the limiting unit for the moving frame 5 to pass through, when the battery cover is in the upper waiting position, the moving frame 5 can carry the sealing ring through the space between the battery cover and the battery case laterally without first moving the battery cover out of the assembly area, thus avoiding the sealing ring transport path from the clamping position of the battery cover.

[0025] When the moving frame 5 moves the adsorption unit above the battery case and aligns the sealing ring with the sealing installation position on the upper surface of the battery case, the moving frame 5 stops moving. The adsorption unit moves downward, gradually bringing the sealing ring closer to the upper surface of the battery case. Because the anti-deviation component cooperates with the sealing ring, it restricts the position of the sealing ring during the falling and initial installation process, so that the sealing ring falls into the corresponding position according to the preset installation contour, reducing the local displacement of the flexible sealing ring caused by its own weight, inertia or the release of the adsorption unit.

[0026] Once the sealing ring and anti-deviation component have engaged and are stably positioned at a predetermined location on the upper surface of the battery casing, the adsorption unit releases its adsorption of the sealing ring and resets upwards, leaving the sealing ring on the battery casing. Subsequently, the moving frame 5, driven synchronously by the two linear guide rails 2, retracts from between the battery casing and the battery cover and moves back to the area where the material box 22 is located, preparing for the next sealing ring retrieval.

[0027] After the movable frame 5 exits between the battery casing and the battery top cover, the clamping unit moves the fixed battery top cover downwards, gradually bringing it closer to the battery casing. Since the sealing ring is pre-positioned on the upper surface of the battery casing by the anti-deviation component, it is less likely to slip laterally during the descent of the battery top cover. As the battery top cover continues to descend, it applies pressure to the sealing ring, stably clamping it between the battery top cover and the battery casing, thus completing the assembly of the battery casing, sealing ring, and battery top cover.

[0028] When it is necessary to install sealing rings on battery cases of different specifications, the corresponding material boxes 22 on both sides of the substrate 1 are selected according to the specifications of the battery case for feeding. The moving frame 5 moves to the corresponding side and the adsorption unit extracts the sealing ring of the matching specifications. There is no need to re-feed all the sealing rings every time the battery case specifications are changed, so that the device can adapt to the sealing assembly requirements of battery cases of different specifications.

[0029] See Figure 1 As shown, the anti-deviation component includes a rectangular block 20 disposed on the surface of the battery case and inserted into the sealing ring. Positioning posts 21 for positioning the sealing ring are provided at the outer and inner edges of the rectangular block 20. The inner cavity of the battery cover has a limiting protrusion that works in conjunction with the limiting groove on the sealing ring.

[0030] After the moving frame 5 moves directly above the battery case, the adsorption unit moves downward, gradually placing the sealing ring on the sealing installation position on the upper surface of the battery case. During the descent of the sealing ring, the rectangular block 20 set on the surface of the battery case first cooperates with the corresponding insertion position on the sealing ring. The rectangular block 20 initially defines the position of the sealing ring, making the overall installation outline of the sealing ring correspond to the sealing area of ​​the battery case. The positioning posts 21 set on the outer and inner edges of the rectangular block 20 respectively limit the sealing ring from the inner and outer sides. When the flexible sealing ring is released and tends to elastically contract or deform locally, the positioning posts 21 located on the inner and outer sides together restrict the lateral movement of the sealing ring, keeping the sealing ring near the rectangular block 20 and the preset sealing area, thereby forming a pre-positioned state for the sealing ring composed of insertion positioning and inner and outer side limiting.

[0031] After the moving frame 5 exits the assembly area, the clamping unit drives the battery cover downwards. As the battery cover gradually approaches the battery casing, the limiting protrusions on the top surface of the inner cavity of the battery cover gradually enter the corresponding limiting grooves on the sealing ring. The limiting protrusions maintain their engagement with the limiting grooves on the sealing ring, restricting the sealing ring from sliding laterally along the surface of the battery casing during the process of the battery cover contacting and pressing the sealing ring. At the same time, the rectangular block 20 and the positioning post 21 on the side of the battery casing continue to restrict the position of the sealing ring from below, so that the sealing ring is positioned by the battery casing side and the battery cover side respectively.

[0032] See Figure 1 and Figure 2 As shown, the limiting unit includes a fixed side plate 3 that abuts against one side of the battery case, and movable side plates 4 that are slidably installed at both ends of the inner wall of the fixed side plate 3, which are close to or far apart from each other. An opening is provided on the side of the substrate 1 away from the fixed side plate 3. A slot 12 is provided in the opening. A sliding lifting component that abuts against the other side of the battery case is installed inside the slot 12. A through groove communicating with the opening is provided on the upper surface of the slot 12.

[0033] First, place the battery case into the limiting unit through the opening on the side of the base plate 1 away from the fixed side plate 3, so that one side of the battery case gradually approaches and abuts against the inner wall of the fixed side plate 3, and the fixed side plate 3 forms a fixed reference for positioning the battery case.

[0034] After the battery case enters the limiting unit, the movable side plates 4 at both ends of the inner wall of the fixed side plate 3 are adjusted according to the current size of the battery case, so that the two movable side plates 4 move closer or further apart from each other, and move to the corresponding positions on the two sides adjacent to the battery case. The two movable side plates 4 limit the battery case from both sides, so that the battery case is kept in the set position in the direction parallel to the fixed side plate 3. At the same time, by changing the distance between the two movable side plates 4, the limiting unit can adapt to battery cases of different widths.

[0035] During the sliding process, the sliding lifting component moves upward, and its upper part extends through the through groove on the upper surface of the slot 12 to the top of the substrate 1 and abuts against the corresponding side of the battery case, pushing the battery case to press against the fixed side plate 3. This allows the battery case to complete the position correction with the fixed side plate 3 as the positioning reference, reducing the possibility of deviation in the overall assembly position caused by the gap between the battery case and the fixed side plate 3 after initial placement.

[0036] See Figure 2 and Figure 4 As shown, the sliding lifting component includes a ramp 17 at the bottom of the inner cavity of the slot 12, a limiting frame 13 that slides along the other side of the battery case at the top of the inner cavity of the slot 12, a clamping plate 7 that is movable and limited inside the limiting frame 13, a spring 14 that is sleeved on the outside of the clamping plate 7 that extends into the limiting frame 13, and an abutment part 16 that contacts the ramp 17 at the bottom of the clamping plate 7, and the top surface of the clamping plate 7 is flush with the through groove. A push cylinder 15 is installed on one side of the inner cavity of the slot 12, and the size of the slot 12 is larger than the size of the through slot. The push end of the push cylinder 15 is fixed to one side of the limiting frame 13. The top surface of the inner cavity of the slot 12 is provided with a sliding groove 18, which slides and limits the movement of the limiting frame 13.

[0037] After the battery case is placed in place, the cylinder 15 is extended, and its pushing end drives the limiting frame 13 to move along the slot 12 towards the other side of the battery case. During the movement of the limiting frame 13, its top is guided and limited by the slide groove 18, so that the limiting frame 13 slides stably in the set direction. As the abutting part 16 gradually moves from the low position of the ramp 17 to the high position, the ramp 17 generates an upward component force on the abutting part 16, so that the clamping plate 7 gradually moves upward relative to the limiting frame 13. At the same time, the spring 14 sleeved on the outside of the clamping plate 7 is compressed. After the clamping plate 7 moves upward, its upper part extends above the base plate 1 through the through groove, thus changing from the initial non-protruding state to a working state that can limit the battery case. While maintaining the upward extension, the clamping plate 7 continues to move laterally with the limiting frame 13 until the clamping plate 7 abuts against the side of the battery case away from the fixed side plate 3. The fixed side plate 3 and the clamping plate 7 limit the battery case from opposite sides, and cooperate with the two movable side plates 4 to limit it from the other two sides, so that the battery case forms a four-sided positioning state.

[0038] After the battery casing is positioned, the moving frame 5 carries the sealing ring between the battery casing and the battery top cover, and places the sealing ring on the upper surface of the battery casing. The rectangular block 20 and the positioning post 21 pre-position the sealing ring. Then, the moving frame 5 retracts, and the clamping unit drives the battery top cover to descend, so that the limiting protrusion on the top surface of the inner cavity of the battery top cover engages with the limiting groove on the sealing ring, further completing the press-fitting between the battery top cover, the sealing ring, and the battery casing. During this process, the clamping plate 7 always maintains a restriction on one side of the battery casing, making it less likely for the battery casing to move due to the external forces generated by the placement of the sealing ring and the pressing-fitting of the battery top cover.

[0039] See Figure 6 As shown, the adsorption unit includes a lifting plate 24 that is lifted and installed at the top of the inner cavity of the movable frame 5, and an adsorption plate 25 that is installed on the bottom surface of the lifting plate 24 for fixed-point adsorption of several points on the sealing ring.

[0040] During material handling, the two linear guide rails 2 synchronously move the movable frame 5 to above the material box 22 containing the corresponding size sealing ring, so that the adsorption plate 25 is basically aligned vertically with the uppermost sealing ring in the material box 22. Subsequently, the lifting plate 24 moves downward relative to the movable frame 5, and simultaneously moves the adsorption plate 25 closer to the sealing ring.

[0041] When the adsorption plate 25 descends to the set height, several adsorption points on it contact or approach the predetermined adsorption positions on the sealing ring, and simultaneously generate an adsorption effect. Since the adsorption positions are distributed along the overall contour of the sealing ring, the sealing ring is not lifted upward by a single position, but is supported by multiple adsorption points, so that each part of the sealing ring is subjected to a relatively dispersed lifting effect.

[0042] After multi-point adsorption is completed, the lifting plate 24 moves upward, driving the adsorption plate 25 and the adsorbed sealing ring to move upward as a whole, so that the sealing ring separates from the lower sealing ring in the material box 22. Since the sealing ring is simultaneously fixed at multiple positions by the adsorption plate 25, during the process of the sealing ring detaching from the material box 22 and subsequent lateral transfer, the situation of the sealing ring sagging, folding, twisting or local stretching caused by localized force can be reduced, so that the sealing ring as a whole remains in an unfolded state close to its predetermined installation contour.

[0043] See Figure 1 and Figure 3 As shown, the clamping unit includes a U-shaped support frame 6. A mounting base 8 is fixedly installed in the middle of the bottom surface of the support frame 6. Two driven bevel gears 19 driven by the driving bevel gear are rotatably installed inside the mounting base 8. A transmission screw 9 is fixed to the end of each driven bevel gear 19. The end of the transmission screw 9 is rotatably set with the corresponding side of the support frame 6. Each drive screw 9 has a threaded clamping component for holding the battery cover. The support frame 6 has a sliding rod installed inside. The clamping component includes a limiting component 11. The bottom surface of the limiting component 11 is connected to a clamping cylinder. The limiting component 11 is slidably arranged with the sliding rod. The two drive ends of the clamping cylinder are respectively connected to clamping blocks 10 that clamp the edge of the battery cover.

[0044] Before clamping the battery cover, the driving bevel gear is activated according to the current size of the battery cover. When the driving bevel gear rotates, it simultaneously drives the two driven bevel gears 19 to rotate. The two driven bevel gears 19 drive the corresponding transmission screws 9 to rotate synchronously. Since the two transmission screws 9 are threadedly connected to the corresponding clamping parts, when the transmission screws 9 rotate, the two clamping parts move synchronously along the lateral side of the support frame 6 under the action of threaded transmission, thereby causing the two clamping parts to move closer to or further away from each other.

[0045] After the two clamping members move to positions corresponding to the two edges of the battery cover, the adjustment action of the transmission screw 9 stops. At this time, the two clamping members are located on opposite sides of the battery cover. The clamping cylinder on the bottom surface of the limiting member 11 then operates. Since each clamping cylinder has two driving ends, the two driving ends drive the corresponding clamping blocks 10 to move closer to each other, so that the two clamping blocks 10 clamp the battery cover from both sides of the edge. By driving the two clamping blocks 10 to move towards each other through the same clamping cylinder, the corresponding edge of the battery cover gradually enters between the two clamping blocks 10 and is clamped by both sides. The clamping members on both sides of the support frame 6 clamp the battery cover at different positions, so that the battery cover maintains a stable posture during the lifting, suspension and lowering pressing process.

[0046] After the battery cover is clamped, the support frame 6 remains above the battery case, ensuring that the battery cover and the battery case within the lower limiting unit are vertically aligned. At this time, an initial height difference is maintained between the battery cover and the battery case to allow the moving frame 5 to pass through. The moving frame 5 can carry the sealing ring adsorbed by the adsorption plate 25 into the space between them and place the sealing ring at a predetermined position on the upper surface of the battery case.

[0047] When replacing battery covers of different sizes and specifications, there is no need to replace the entire clamping unit. Simply drive the active bevel gear again, and the two driven bevel gears 19 will synchronously drive the corresponding transmission screws 9 to rotate, so that the two clamping parts are adjusted to the position corresponding to the current battery cover. Then, the clamping cylinder and clamping block 10 are used to complete the clamping, which can adapt to battery covers of different widths or different shapes and sizes.

[0048] See Figure 1 As shown, a guide groove 26 is provided on the upper surface edge of the substrate 1 and on one side adjacent to the linear guide rail 2. The guide groove 26 is slidably disposed with the movable frame 5.

[0049] When the two linear guides 2 move synchronously, they drive the movable frame 5 to move along the base plate 1 through the corresponding connecting frame 27. While the movable frame 5 moves, its corresponding part slides synchronously along the guide groove 26. The guide groove 26 further restricts the movement direction of the movable frame 5, enabling the movable frame 5 to reciprocate between the two material boxes 22 and the limiting unit along a predetermined path.

[0050] In use, the present invention uses an anti-deviation component to pre-position the sealing ring and uses the battery cover to press the sealing ring in place after it is lowered. This ensures that the sealing ring is already positionally constrained before being pressed by the battery cover, improving the consistency and stability of the subsequent sealing of the cover. The moving frame 5 carries the sealing ring laterally through the space between the battery cover and the battery case without having to remove the battery cover from the assembly area first. This allows the sealing ring transport path to avoid the clamping position of the battery cover. By setting material boxes 22 on both sides of the limiting unit to hold the sealing rings of the corresponding specifications, sealing rings of different specifications can be stored separately. The moving frame 5 moves to the corresponding material box 22 according to the current battery case specification to retrieve the material. When switching between different battery case specifications, it is not necessary to frequently empty the material box 22 and replace the entire batch of sealing rings, shortening the preparation time required for specification switching and improving the adaptability of the mounting structure to different battery case specifications. By setting a limiting unit and a sliding lifting component, the battery case slides in through the opening, pushing the battery case close to the fixed side plate 3, so that the battery case completes the position correction with the fixed side plate 3 as the positioning reference. During the movement of the limiting frame 13, its top is guided and limited by the slide groove 18, so that the limiting frame 13 slides stably in the set direction. As the abutment part 16 gradually moves from the low position of the ramp 17 to the high position, the ramp 17 generates an upward component force on the abutment part 16, so that the clamping plate 7 gradually moves upward relative to the limiting frame 13, and at the same time compresses the spring 14 sleeved on the outside of the clamping plate 7. The fixed side plate 3 and the clamping plate 7 limit the battery case from the opposite sides respectively, and cooperate with the two movable side plates 4 to limit it from the other two sides, so that the battery case forms a four-sided positioning state to adapt to different specifications of battery cases. By setting up a clamping unit, and by setting two driven bevel gears 19 inside the mounting base 8, which are driven by the active bevel gear, and by driving the corresponding clamping parts synchronously closer or further away through two transmission screws 9, the clamping unit can change the distance between the two clamping parts according to the size of the battery cover of different specifications. This allows the same clamping unit to be applicable to battery covers of various sizes, reducing the need to replace the entire clamping fixture after changing the battery cover size. By using a clamping cylinder to drive two clamping blocks 10 to clamp the corresponding edges of the battery cover in opposite directions, the edges of the battery cover are subjected to the combined action of both sides, reducing the problem of the battery cover shifting easily when using unilateral pushing clamping. Furthermore, the clamping space between the two clamping blocks 10 can form a certain clamping effect on the edges of the battery cover, improving the stability of the battery cover during lifting and lowering.
