Description

Technical Field

[0001] This utility model relates to the field of battery cell processing equipment technology, and in particular to a multi-faceted flipping clamp for battery cells. Background Technology

[0002] In the production and manufacturing process of new energy batteries, the cells often need to go through multiple processes such as cleaning, gluing, and testing before and after packaging. In order to ensure processing accuracy and safety, special fixtures are usually used to fix the cells.

[0003] However, most existing battery cell clamps use a single-directional fixing method, meaning that after the battery cell is fixed to the operating table by a cylinder or robotic arm, its position and orientation remain stationary. This static clamping method means that the bottom of the battery cell and the sides covered by the clamp cannot be directly exposed to the processing head (such as a cleaning nozzle or inspection probe). If multiple sides of the battery cell need to be fully covered, the production line often needs to be stopped, and the battery cell needs to be manually removed, flipped, and re-fixed, or multiple processes need to be set up to transfer the battery cell to different workstations for reorientation. This traditional operation mode not only leads to a cumbersome production process and low work efficiency, but also makes it very easy to cause bumps or scratches to the surface of the battery cell during repeated manual handling and secondary clamping, making it difficult to meet the high-efficiency and high-yield production requirements of modern production lines.

[0004] Therefore, this utility model proposes a multi-faceted flipping clamp for battery cells to overcome the shortcomings of the prior art. Utility Model Content

[0005] In the existing technology, battery cell processing fixtures usually adopt a static fixing method in one direction, which results in blind spots in the processing of the bottom and obscured sides of the battery cell. To achieve all-round processing, manual intervention is required to flip the cell or transfer it multiple times. This leads to problems such as cumbersome production process, low work efficiency, easy damage to the surface of the battery cell caused by manual handling, and low reliability. The present invention aims to provide a battery cell multi-face flipping clamping fixture with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a multi-faceted flipping clamp for battery cells, including: a support fixing plate; and a clamping assembly and a flipping assembly disposed on the support fixing plate.

[0007] The clamping assembly includes a fixed support fixedly connected to the top of the support plate, a clamping feed screw guide rail fixedly connected inside the fixed support, a clamping servo motor fixedly connected to one end of the clamping feed screw guide rail, and a support frame slidably connected to the clamping feed screw guide rail via a feed block. The clamping servo motor drives the support frame to move horizontally. The flipping assembly includes a lateral flipping mechanism and a central lifting mechanism. The lateral flipping mechanism includes a flipping servo motor fixedly connected to the outside of the support frame and a flipping clamping fixture rotatably connected to the inside of the support frame. The output shaft of the flipping servo motor passes through the support frame and is fixedly connected to the flipping clamping fixture. The central lifting mechanism includes a hydraulic cylinder body installed inside the support plate, a hydraulic push rod slidably connected to the top of the hydraulic cylinder body, a horizontal rotary lifting cylinder fixedly connected to the top of the hydraulic push rod, and a fixture fixedly connected to the top of the horizontal rotary lifting cylinder.

[0008] Furthermore, the clamping assembly drives the support frame to perform horizontal displacement through the clamping feed screw guide rail, thereby causing the lateral flipping mechanism to move closer to or away from the fixture on the central lifting mechanism. The lateral flipping mechanism and the central lifting mechanism cooperate in spatial position through the movement of the support frame to realize the handover, clamping and attitude adjustment of the battery cell.

[0009] Preferably, the clamping assembly further includes a slide rail disposed on the top of the support fixing plate and a slider slidably connected to the slide rail. The slide rail is located inside the fixed support and parallel to the clamping feed screw guide rail. The top of the slider is fixedly connected to the bottom of the support frame. Through the cooperation between the slider and the slide rail, the weight of the support frame is assisted in bearing and guidance is provided to ensure the stability of the movement process.

[0010] Preferably, the flipping assembly further includes a soft pad fixedly connected to one side of the flipping clamping fixture and a retraction probe movably connected inside the soft pad. The soft pad is located on the side of the flipping clamping fixture away from the flipping servo motor. The detection end of the retraction probe passes through the soft pad and extends to the outside, and is used to contact the surface of the battery cell before the soft pad during clamping to trigger sensing.

[0011] Preferably, the other end of the shrink probe is movably connected to the flip clamping fixture, and an elastic reset member is connected between the shrink probe and the flip clamping fixture. The shrink probe is configured to retract into the soft pad when it is subjected to force on the contact cell surface, and the elastic reset member is used to realize automatic reset after the external force is removed.

[0012] Preferably, the flipping assembly further includes a pressure relief valve connected to the left side of the hydraulic cylinder body and a protective plate fixedly connected to the rear side of the hydraulic cylinder body. The protective plate extends vertically upward to shield the hydraulic cylinder body, thereby preventing external debris or liquid from damaging the hydraulic system.

[0013] Preferably, the clamping assembly has two sets and is symmetrically distributed about the fixture. The clamping feed screw guide is configured to drive the two sets of support frames to clamp synchronously in opposite directions or separate in opposite directions, thereby realizing bidirectional synchronous centering clamping of the battery cell.

[0014] Preferably, the fixture has a groove-shaped structure with an open top, and the fixture is located directly below the two flip clamping fixtures. The horizontal rotary lifting cylinder is used to drive the fixture to rotate in the horizontal plane so as to adjust the processing angle of the battery cell in the horizontal direction.

[0015] Preferably, the bottom of the support fixing plate is provided with several shock-absorbing support feet, the fixed support is fixedly connected to the support fixing plate by bolts, and the clamping servo motor is fixedly connected to the clamping feed screw guide rail by a coupling, so as to improve the connection rigidity and operation stability of the overall device.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a central lifting and rotating mechanism and a side clamping and flipping mechanism, uses a hydraulic push rod in conjunction with a horizontal rotating cylinder to realize the height adjustment and horizontal rotation of the battery cell. At the same time, a servo motor drives the side clamp to perform horizontal feeding and vertical flipping. This solves the problem that the battery cell clamps in the prior art can usually only fix a single posture and cannot automatically perform multi-face reversal, resulting in blind spots in processing. It achieves the technical effect of cleaning or processing the battery cell from all directions and multiple angles without manual intervention, significantly improving production efficiency and automation.

[0018] 2. This utility model solves the problem that existing rigid clamping devices are prone to scratching or deformation of the battery cell surface due to improper force control. It achieves the technical effects of flexible protection of the battery cell, precise control of clamping force, and effective reduction of battery cell breakage rate.

[0019] 3. This utility model, by adopting a moving structure of clamping feed screw guide rail in conjunction with auxiliary slide rail and slider, utilizes the slider to share the weight of the support frame and provide guidance, which solves the problem that existing large clamps are prone to shaking and unstable operation due to high frictional resistance during long-distance movement. It achieves the technical effects of reducing operating energy consumption, ensuring smooth and stable clamping and feeding action, and improving centering accuracy. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model provides a multi-faceted flipping clamp for battery cells, which aims to solve the structural defects of existing battery cell processing and cleaning processes, which are difficult to automatically achieve multi-faceted flipping, resulting in low cleaning efficiency and easy damage to battery cells.

[0029] like Figure 1 and Figure 2As shown, the multi-faceted flipping clamping fixture for battery cells includes a support and fixing plate 3, and a clamping component 1 and a flipping component 2 disposed on the support and fixing plate 3. The support and fixing plate 3 serves as the mounting base for the overall device, and its bottom is provided with a structure for fixing, which can be stably installed on the ground or other supporting and fixing devices, providing a stable support platform for the clamping component 1 and the flipping component 2. The clamping component 1 is used to realize the opposing movement and locking of the structures on both sides of the device, while the flipping component 2 is responsible for realizing the attitude adjustment and multi-faceted flipping of the battery cells.

[0030] Specifically, the clamping assembly 1 includes a fixed support 106 fixedly connected to the top of the support plate 3. A clamping feed screw guide rail 103 is rotatably connected inside the fixed support 106. A clamping servo motor 101 is fixedly connected to one end of the clamping feed screw guide rail 103 away from the fixed support 106. The clamping servo motor 101 serves as a power source to drive the clamping feed screw guide rail 103 to rotate. A feed block is threadedly connected to the outer side of the clamping feed screw guide rail 103. A support frame 102 is fixedly connected to the top of the feed block. By driving the clamping feed screw guide rail 103 to rotate through the clamping servo motor 101, the feed block and the support frame 102 fixed thereon are driven to reciprocate in the horizontal direction, thereby achieving precise control of the position of the support frame 102. This, in turn, causes part of the structure of the flipping assembly 2 installed on the support frame 102 to move closer to or away from the center.

[0031] To further improve the stability of the support frame 102 during movement and reduce frictional resistance, a slide rail 104 is fixedly connected to the top of the support fixing plate 3. The slide rail 104 is located inside the fixed support 106, and the length direction of the slide rail 104 is parallel to the axial direction of the clamping feed screw guide rail 103. A slider 105 is slidably connected to the slide rail 104. The top of the slider 105 is fixedly connected to the bottom of the support frame 102. When the support frame 102 moves, the slider 105 slides on the slide rail 104. This dual guide structure can not only share the weight of the support frame 102 and its load, but also effectively prevent the support frame 102 from deflecting during movement, ensuring the synchronization and stability of the clamping action. At the same time, it reduces the resistance of the support frame 102 movement, reduces energy consumption, and makes the operation smoother.

[0032] Furthermore, in order to adapt to the clamping requirements of battery cells of different sizes and to ensure the balance of clamping force, the clamping assembly 1 is provided with two sets. The two sets of clamping assemblies 1 are symmetrically distributed on both sides of the support fixing plate 3 about the center of the device. The clamping feed screw guide rail 103 is configured as a bidirectional screw structure or two independently controlled screw structures, so that when the clamping servo motor 101 is working, it can drive the support frames 102 on both sides to move towards the center synchronously for clamping, or to separate outward to release space, providing the necessary action basis for the subsequent operation of the flipping assembly 2.

[0033] To solve the above-mentioned technical problems, the flipping component 2 of the multi-sided flipping clamping fixture for battery cells includes a lateral flipping mechanism that can realize lateral clamping and flipping. Furthermore, the lateral flipping mechanism and the aforementioned support frame 102 form a specific structural cooperation and connection relationship, thereby realizing the flexible flipping of the side of the battery cell.

[0034] Please refer to the following carefully. Figure 1 and Figure 3 The core structure will be described in detail below:

[0035] The lateral flipping mechanism in the flipping assembly 2 mainly consists of a flipping servo motor 201 and a flipping clamping fixture 202. The flipping servo motor 201, as the power output source for the flipping action, is fixedly connected to the outer wall of the support frame 102. Its output shaft passes through the support frame 102 and extends to the inner side. The flipping clamping fixture 202 is rotatably connected to the inner side of the support frame 102 and is fixedly connected to the output shaft of the flipping servo motor 201. When the flipping servo motor 201 receives a control signal and starts, its output shaft can drive the flipping clamping fixture 202 to rotate vertically. The flipping clamping fixture 202 is responsible for directly clamping the battery cell laterally. It has sufficient rigidity and clamping surface to ensure the stability of the battery cell's posture during the flipping process.

[0036] To further protect the surface of the battery cell from damage and prevent over-clamping, the flipping assembly 2 also includes a soft pad 203 fixedly connected to one side of the flipping clamping fixture 202. The soft pad 203 is located on the side of the flipping clamping fixture 202 away from the flipping servo motor 201, that is, the side directly facing the battery cell clamping surface. The soft pad 203 is made of a flexible material with a certain elasticity, which can provide buffer protection during clamping and prevent the hard fixture from directly contacting the battery cell, causing scratches or pressure damage. A mounting through hole is provided on the side of the soft pad 203 facing the battery cell. A shrinkage probe 209 is movably inserted into the mounting through hole. The detection end of the shrinkage probe 209 passes through the soft pad 203 and extends to the outside, so as to contact the battery cell surface before the soft pad 203 during the clamping process.

[0037] Meanwhile, the other end of the shrink probe 209 is movably connected to the inside of the flip clamping fixture 202, and an elastic reset element is connected between the shrink probe 209 and the flip clamping fixture 202. The shrink probe 209 is configured to retract into the soft pad 203 when it is subjected to force on the surface of the battery cell. This design constitutes a precise contact sensing mechanism. When the clamping assembly 1 drives the flip clamping fixture 202 to approach the battery cell, the shrink probe 209 first contacts the battery cell and is pushed back. By detecting the position change or force condition of the shrink probe 209, the clamping servo motor 101 can be precisely controlled to stop, thereby preventing damage to the battery cell due to excessive clamping force. This achieves flexible and safe clamping of the battery cell. After confirming that the clamping is in place and safe, the flip servo motor 201 is started, driving the flip clamping fixture 202 and the clamped battery cell to be vertically flipped, exposing the bottom or other sides of the battery cell for comprehensive cleaning or processing.

[0038] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0039] As a preferred embodiment, in order to achieve stable support for the bottom of the battery cell and cooperate with lateral clamping, the fixture 204 in the central lifting mechanism is designed as a groove-shaped or U-shaped structure with an open top. The fixture 204 is fixedly connected to the top output end of the horizontal rotary lifting cylinder 205 and is located at the center position directly below the two flip clamping fixtures 202. This structure can ensure the stability of the battery cell when initially placed. At the same time, in order to increase friction and prevent rigid contact from damaging the bottom of the battery cell, an anti-slip buffer layer is pasted on the inner wall surface of the fixture 204. The horizontal rotary lifting cylinder 205 drives the fixture 204 to adjust its angle in the horizontal plane through its rotation. With the vertical lifting of the hydraulic push rod 207, the battery cell can be adjusted to the optimal processing height and angle.

[0040] As a preferred embodiment, in order to ensure the safe operation of the hydraulic system and the physical protection of the structure, the central lifting mechanism is also equipped with a complete set of protective components. The hydraulic cylinder is fixedly installed inside or at the bottom of the support plate 3. The hydraulic push rod 207 is slidably connected inside the hydraulic cylinder and extends upward. A pressure relief valve 208 is connected to the left side of the hydraulic cylinder. The pressure relief valve 208 is used to monitor and regulate the pressure in the hydraulic circuit to prevent excessive pressure from damaging the pipeline or components. At the same time, a protective plate 206 is fixedly connected to the rear side of the hydraulic cylinder. The protective plate 206 extends vertically upward and is higher than the height of the main body of the hydraulic cylinder, thus forming a physical barrier to prevent external debris, cleaning fluid splashes, or accidental collisions from damaging the precision hydraulic components.

[0041] In a preferred embodiment, to ensure the reusability accuracy of the detection mechanism, the resetting action of the shrink probe 209 is achieved through a built-in elastic component. An elastic resetting element, such as a compression spring, is provided inside the flip clamping fixture 202 at the connection point with the shrink probe 209. One end of the elastic resetting element abuts against the inner wall of the flip clamping fixture 202, and the other end abuts against the shrink probe 209. When the external force is removed, the elastic resetting element releases elastic potential energy to drive the shrink probe 209 to push outward and reset, waiting for the next sensing trigger.

[0042] In a preferred embodiment, to achieve bidirectional synchronous clamping to improve efficiency and ensure smooth power transmission, the clamping assembly 1 is symmetrically distributed on the support plate 3. The clamping feed screw guide rail 103 is designed as a bidirectional screw structure, that is, the threads at both ends of the screw turn in opposite directions, or two sets of independently controlled screw guide rails are used. When the clamping servo motor 101 drives the screw to rotate, the two side support frames 102 can synchronously move towards the center to apply symmetrical clamping force to the battery cell. The output shaft of the clamping servo motor 101 and the screw end of the clamping feed screw guide rail 103 are fixedly connected by a coupling. At the same time, the bottom of the support plate 3 is provided with several shock-absorbing support feet, which effectively absorb the vibration generated during the operation of the device and improve the stability of the whole machine.

[0043] The working principle of this utility model's multi-faceted flipping clamp for battery cells is as follows:

[0044] When using this device, the battery cell to be processed is first placed inside the fixture 204. At this time, the fixture 204 is located below the center of the two flip clamping fixtures 202. The drive system is started, and the hydraulic push rod 207 slides and rises and falls inside the hydraulic cylinder, driving the top horizontal rotating lifting cylinder 205 and the fixture 204 to adjust to the preset working height. At the same time, the horizontal rotating lifting cylinder 205 drives the fixture 204 to rotate in the horizontal plane according to the processing requirements. With the help of external cleaning or testing equipment, the sides of the battery cell are initially processed. During this process, the protection plate 206 always provides shielding and protection for the hydraulic cylinder. The pressure relief valve 208 adjusts the hydraulic system pressure in real time to maintain stable system operation and prevent abnormal pressure from damaging the equipment.

[0045] When the battery cell needs to be vertically flipped to process other sides, the clamping servo motor 101 is started, driving the clamping feed screw guide rail 103 to rotate. Through the screw drive, the support frames 102 on both sides move synchronously towards the center. The slider 105 at the bottom of the support frame 102 slides smoothly on the slide rail 104. The cooperation between the slide rail 104 and the slider 105 not only reduces the frictional resistance of the support frame 102 movement and reduces energy consumption, but also ensures the straightness and stability of the feed action. As the support frame 102 gets closer, the retraction probe 209 installed on the flipping clamping fixture 202 contacts the surface of the battery cell first. After being squeezed, it overcomes the resistance of the elastic reset member and retracts into the soft pad 203. This contact action triggers position feedback or pressure detection, controlling the clamping servo motor 101 to stop feeding. At this time, the soft pad 203 is just tightly attached to the side of the battery cell to complete the flexible clamping, effectively preventing the battery cell from being deformed or damaged due to excessive clamping force.

[0046] After the battery cell is firmly clamped by the flip clamping fixtures 202 on both sides, the hydraulic push rod 207 drives the fixture 204 to descend and make way to reserve flipping space. Then, the flip servo motor 201 is started. The output shaft of the flip servo motor 201 drives the flip clamping fixture 202 and the clamped battery cell to rotate and flip in the vertical direction, thereby exposing the bottom or top surface of the battery cell that was originally covered, completing the all-round cleaning or processing of the battery cell. After all the processes are completed, the flip servo motor 201 is reset, and the clamping servo motor 101 reverses to drive the support frame 102 to separate and release the battery cell, completing the entire work cycle.

[0047] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the protection scope of the claims.
