Description

Technical Field

[0001] This invention relates to the field of lithium battery assembly technology, specifically to a high-efficiency re-acting release paper tearing clamp. Background Technology

[0002] The lithium-ion battery assembly process involves systematically assembling, connecting, and protecting individual lithium-ion battery cells (square cells) to form a battery pack (or battery module) with specific voltage, capacity, and functions, in order to meet the high voltage and high capacity requirements of end devices (such as electric vehicles, energy storage systems, and consumer electronics). Its core objective is to ensure the consistency, safety, reliability, and performance stability of the battery pack.

[0003] During the assembly of lithium battery modules, foam or silicone cushioning pads with release paper are typically attached between cells and at module end plates. These release paper pads must be completely peeled off before attachment. Existing release paper removal methods use a long-stroke cylinder coupled with a gripper cylinder at the moving end to peel the release paper and transport it to a waste bin before returning to the peeling position in a reciprocating motion. However, this method uses two separate power sources—the cylinder and the gripper cylinder—resulting in a complex structure, high cost, and high failure rate. It is prone to asynchronous clamping and tearing actions, leading to release paper breakage, residue, and slippage. Furthermore, the high rigidity of the gripper cylinder can easily damage the cushioning pad, affecting battery safety.

[0004] In view of this, there is an urgent need to provide a clamping mechanism that uses only a single power source to achieve a continuous repeating action of first clamping, then pulling to tear the paper, and then resetting. This mechanism should be extremely simple in structure, reliable in operation, and does not damage the buffer pad, thus providing a highly efficient repeating paper tearing clamp to solve the problem. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a high-efficiency re-acting release paper tearing clamp.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A high-efficiency reciprocating release paper tearing clamp includes a fixed base, a single-power drive mechanism, a sliding mechanism, a clamping mechanism, and an elastic reset mechanism. The sliding mechanism includes a fixed member and two sliding members mounted on the fixed member. The fixed member is installed on the fixed base, and the two sliding members are linked and engaged. An elastic reset mechanism is assembled between the two sliding members. The clamping mechanism includes a clamping arm and a clamping stationary arm, which are respectively fixed to the two sliding members. The single-power drive mechanism is installed on the fixed base, and its output end is connected to one of the sliding members. The single-power drive mechanism drives the sliding member to reciprocate along the fixed member, and in conjunction with the elastic reset mechanism, enables the clamping mechanism to sequentially complete the continuous reciprocating actions of clamping, tearing, releasing, and resetting.

[0007] The beneficial effects of this invention are: 1. The single-power drive mechanism is used as the only power source to replace the existing dual-cylinder drive scheme, eliminating the need for additional gripper drive and supporting air circuit control components. The overall structure is simple and compact, effectively reducing the overall manufacturing cost, assembly complexity and subsequent operation and maintenance cost. 2. By setting an elastic reset mechanism between each sliding component of the sliding mechanism, the relative motion of the sliding components combined with the deformation and rebound characteristics of the elastic reset mechanism can realize the orderly timing of clamping, tearing, releasing and resetting in a purely mechanical linkage manner. It does not require precise matching of the electronic control program, effectively avoiding problems such as asynchronous clamping and tearing actions, release paper tearing, residue and clamping slippage, and greatly improving the stability and yield of paper tearing operation. 3. The overall modular layout is reasonable, with a small space occupation. It can be easily integrated and installed on the rack of lithium battery module PACK assembly equipment or module transfer mechanism, adapting to various workstation installation scenarios. It has strong versatility and can meet the continuous and stable operation requirements of automated production lines. 4. By utilizing the elastic buffering effect of the elastic reset mechanism, the clamping force is made flexible and controllable, avoiding excessive rigid clamping pressure that could damage workpieces such as lithium battery buffer pads; at the same time, the mechanism can automatically reset without manual intervention, enabling fully automated cyclic operation, adapting to continuous operation conditions on production lines, and effectively improving production efficiency and safety.

[0008] Furthermore, the fixed base includes a mounting plate, which has a guide rail mounting surface, a cylinder tailstock, and a waste bin clearance opening. The fixed base provides a unified mounting reference for the linear guide rail, cylinder, and limiting structure, ensuring the installation accuracy and coaxiality of each component.

[0009] Furthermore, the fixing component of the sliding mechanism includes a linear guide rail, and the sliding component includes a front slide and a rear slide. The linear guide rail is fixedly installed on the guide rail mounting surface of the fixed base. Both the front and rear slides are slidably mounted on the linear guide rail via sliders, and the front and rear slides are linked by guide rods. The linear guide rail ensures the straightness and stability of the reciprocating motion of the front and rear slides, preventing deviation during the paper tearing action and avoiding the release paper from being torn. The guide rod linkage design provides a basis for synchronization and guidance of the front and rear slides, and also provides a reliable carrier for the subsequent installation of the elastic reset mechanism.

[0010] Furthermore, the rear slide is fixedly connected to the guide rod, and the front slide is slidably connected to the guide rod. An elastic reset mechanism is provided on the guide rod between the front and rear slides. The guide rod guides the sliding of the front slide, ensuring uniform force on the elastic reset mechanism and preventing jamming. The elastic reset mechanism achieves elastic linkage between the front and rear slides through the guide rod, providing power for the mechanical timing control of clamping followed by tearing. Simultaneously, the elastic reset mechanism allows the clamp to automatically release during the reset phase without additional drive.

[0011] Furthermore, the clamping arm is fixed to the front slide, and the clamping stationary arm is fixed to the rear slide, with their clamping surfaces forming a wedge-shaped fit. The clamping mechanism can be opened and closed simply by the relative displacement of the front and rear slides, requiring no additional clamping drive, resulting in a minimalist structure and low failure rate. Simultaneously, the wedge-shaped fit structure utilizes the relative movement of the front and rear slides to achieve a self-locking effect that tightens as the clamping progresses, preventing slippage during clamping and ensuring stable holding of the release paper.

[0012] Furthermore, both the moving and stationary arms of the clamp are provided with an anti-slip layer on their clamping surfaces. The anti-slip layer increases the friction between the clamping surface and the release paper, improves clamping reliability, and prevents the release paper from slipping off during the tearing process.

[0013] Furthermore, the single-power drive mechanism includes a cylinder, the cylinder body of which is fixedly mounted on the cylinder tailstock of the fixed base, and the piston rod is connected to the front slide via a floating joint. The cylinder is a common power source for industrial automation, with mature technology and high reliability, suitable for the continuous operation of lithium battery production lines; the floating joint can compensate for the coaxiality error between the cylinder and the slide, preventing wear or jamming of the piston rod due to lateral forces.

[0014] Furthermore, the elastic reset mechanism employs a reset spring. The spring has a fast response speed and no mechanical backlash, ensuring rapid and stable execution of clamping and reset actions, thus improving production cycle time.

[0015] Furthermore, the fixed base is equipped with a front limit seat and a rear limit seat. The front limit seat is used to limit the initial position of the front slide, and the rear limit seat is used to limit the maximum retracted position of the rear slide. The front limit seat ensures that the clamp and release paper are accurately aligned in the standby state, preventing the clamp from accidentally hitting the buffer pad body and preventing workpiece damage. The rear limit seat controls the paper tearing stroke, ensuring that the release paper is accurately fed into the waste bin after being completely torn off, avoiding residue.

[0016] Furthermore, a photoelectric sensor is installed on the side of the fixing base. The photoelectric sensor can monitor in real time whether the release paper is successfully clamped and torn off. Attached Figure Description

[0023] like Figure 1 , Figure 2 As shown, this embodiment provides a high-efficiency reciprocating release paper tearing clamp, including a fixed base 1, a single power drive mechanism 2, a sliding mechanism, a clamping mechanism, and an elastic reset mechanism; The sliding mechanism includes a fixing member 3 and two sliding members disposed on the fixing member. The fixing member 3 is installed on the fixed base 1. The two sliding members are linked and cooperated, and an elastic reset mechanism 7 is assembled between the two sliding members. The clamping mechanism includes a clamping arm 8 and a clamping arm 9, which are respectively fixed on two sliding parts. The single-power drive mechanism 2 is installed on the fixed base 1, and its output end is connected to one of the sliding parts. The single-power drive mechanism 2 drives the sliding part to reciprocate along the fixed part 3, and cooperates with the elastic reset mechanism 7 to enable the clamping mechanism to complete the continuous reciprocating action of clamping, tearing paper, releasing and resetting in sequence.

[0024] This embodiment aims to overcome the shortcomings of existing release paper tearing mechanisms, which often employ dual-cylinder combinations for drive, resulting in complex structures, high component costs, and cumbersome pneumatic control. It also addresses issues such as asynchronous clamping and tearing actions relying on electronic timing matching, easy tearing and residue of release paper, slippage during clamping, workpiece damage from rigid clamping, the need for manual resetting, and poor integration adaptability. By adopting a single power source combined with a sliding mechanism and an elastic resetting mechanism in a purely mechanical linkage structure, the overall layout is simplified, manufacturing costs and maintenance difficulty are reduced, and fully automatic and orderly timing actions for clamping, tearing, releasing, and resetting are achieved. This ensures stable and reliable tearing operations, flexible and controllable clamping force to prevent workpiece damage, and a compact, easy-to-install, and highly versatile design that meets the continuous and efficient operation requirements of automated lithium battery module PACK production lines.

[0025] Specifically: The fixed base 1 includes a mounting base plate, which has a guide rail mounting surface, a cylinder tailstock, and a waste bin clearance opening. The fixed base 1 provides a unified mounting reference for the linear guide rail, cylinder, and limiting structure, ensuring the installation accuracy and coaxiality of each component; at the same time, the waste bin clearance opening can directly connect to the equipment's waste collection device, simplifying the release paper collection process, and facilitating the overall installation of the clamps on different models of PACK equipment or transfer modules, demonstrating strong adaptability.

[0026] The fixing component 3 of the sliding mechanism includes a linear guide rail, and the sliding component includes a front slide 4 and a rear slide 5. The linear guide rail is fixedly installed on the guide rail mounting surface of the fixed base 1. Both the front slide 4 and the rear slide 5 are slidably mounted on the linear guide rail by sliders, and the front slide 4 and the rear slide 5 are linked by a guide rod 6. The linear guide rail ensures the straightness and stability of the reciprocating motion of the front and rear slides 5, preventing deviation in the paper tearing action and avoiding the release paper from being torn. The linkage design of the guide rod 6 provides a synchronous and guiding basis for the front and rear slides 5, and at the same time provides a reliable carrier for the subsequent installation of the elastic reset mechanism 7.

[0027] The rear slide 5 is fixedly connected to the guide rod 6 (e.g., by thread), and the front slide 4 is slidably connected to the guide rod 6 (a guide hole is provided at a corresponding position on the front slide 4, through which the guide rod 6 slides and engages with the front slide 4, ensuring that the front slide 4 can slide smoothly along the axial direction of the guide rod 6). An elastic reset mechanism 7 is provided on the guide rod 6 between the front slide 4 and the rear slide 5. The guide rod 6 guides the sliding of the front slide 4, ensuring that the elastic reset mechanism 7 is subjected to uniform force and avoiding jamming. The elastic reset mechanism 7 achieves elastic linkage between the front and rear slides 5 through the guide rod 6, providing power for the mechanical timing control of clamping followed by tearing paper. Simultaneously, the elastic reset mechanism 7 allows the clamp to automatically release during the reset phase without additional drive.

[0028] The clamping arm 8 is fixed (e.g., by bolts) to the front slide 4, and the clamping arm 9 is fixed to the rear slide 5. The clamping surfaces of the two are wedge-shaped, with a wedge angle ranging from 30° to 45°. The clamping mechanism can be opened and closed simply by the relative displacement of the front and rear slides 5, without any additional clamping drive, resulting in a very simple structure and low failure rate. At the same time, the wedge-shaped structure can utilize the relative movement of the front and rear slides 5 to achieve a self-locking effect that tightens as the clamping progresses, preventing slippage during clamping and ensuring stable clamping of the release paper. The guiding effect of the wedge-shaped surface can also automatically center the release paper, reducing the alignment accuracy requirements between the clamp and the release paper and simplifying equipment debugging.

[0029] Both the clamping surfaces of the movable clamp arm 8 and the stationary clamp arm 9 are provided with an anti-slip layer. The anti-slip layer can be made of a flexible material (such as rubber or silicone) with a thickness of 0.5-1mm. This can increase the friction between the clamping surface and the release paper, improve clamping reliability, and prevent the release paper from slipping during the tearing process. It can also prevent the rigid metal surface from scratching the release paper.

[0030] The single-power drive mechanism 2 includes a cylinder. The cylinder body is fixedly mounted on the cylinder tailstock of the fixed base 1, and the piston rod is connected to the front slide 4 through a floating joint 13. The cylinder is a general-purpose power source for industrial automation, with mature technology and high reliability, suitable for the continuous operation of lithium battery production lines. The extension and retraction speed of the cylinder can be adjusted by the inlet throttle valve to meet the clamping and tearing requirements of release paper of different specifications. The floating joint 13 can compensate for the coaxiality error between the cylinder and the slide, avoiding wear or jamming of the piston rod due to lateral force.

[0031] The elastic reset mechanism 7 uses a reset spring, which is sleeved on the guide rod 6. One end of the spring abuts against the rear end face of the front slide 4, and the other end abuts against the front end face of the rear slide 5. In its natural state, it is slightly pre-tightened, ensuring that the front and rear slides maintain their initial relative positions during standby. The spring has a fast response speed and no mechanical backlash, ensuring rapid and stable execution of clamping and reset actions, thus improving production cycle time. At the same time, the spring is a standard part, which is low in cost, easy to purchase, and convenient to maintain and replace, reducing the equipment's operation and maintenance costs. Moreover, the spring force can be adjusted by the pre-tightening force to adapt to release papers of different thicknesses and materials, and the clamping force is controllable, avoiding breaking the release paper or damaging the buffer pad.

[0032] The fixed base 1 is equipped with a front limit seat 10 and a rear limit seat 11. The front limit seat 10 is used to limit the initial position of the front slide 4, and the rear limit seat 11 is used to limit the maximum retracted position of the rear slide 5. Adjustable limit bolts can be installed at both the front limit seat 10 and the rear limit seat 11, so that the limit position can be adjusted according to different product specifications. The front limit seat 10 can ensure that the clamp and the release paper are accurately aligned in the standby state, avoiding accidental contact between the clamp and the buffer pad body, and preventing damage to the workpiece. The rear limit seat 11 can control the tearing stroke, ensuring that the release paper is accurately sent into the waste bin after being completely torn off, avoiding residue. The limit seats can be adjusted to adapt to different product specifications, making changeover and debugging simple, without the need to modify the program, thus improving the versatility of the equipment.

[0033] A photoelectric sensor 12 (such as PM-T45P-2) is installed on the side of the fixed base 1. The photoelectric sensor 12 can be fixed to the mounting plate of the fixed base 1 by a bracket, with the detection end aligned with the clamping port of the clamping mechanism. The photoelectric sensor 12 can be connected to the control system and alarm system of the PACK equipment via wires. The photoelectric sensor 12 can monitor in real time whether the release paper is successfully clamped and torn. When tearing, residue, or clamping failure occurs, it can promptly feed back a signal to the control system, triggering an alarm or shutdown to prevent defective products from flowing into the next process; it provides closed-loop feedback for the equipment, improves the automation and intelligence level of the paper tearing process, and reduces the cost of manual inspection; at the same time, the photoelectric sensor 12 is a non-contact detection, with no mechanical wear, fast response speed, and does not affect the normal operation of the clamp.

[0034] The working principle of the above structure: During operation, the clamp assembly relies on the fixed base 1 as the installation reference and is powered by a single-power drive mechanism 2 for reciprocating motion. Through the cooperation of the sliding mechanism, clamping mechanism, and elastic reset mechanism 7, the clamping, tearing, releasing, and resetting actions are achieved through pure mechanical linkage, resulting in fully automatic sequential actions. The specific working process is as follows: 1. Workstation debugging a. Move the paper-tearing clamp of this embodiment to the corresponding paper-tearing station of the product, and adjust the height of the fixed base 1 so that the clamping mouth is aligned with the height of the release paper of the product's buffer pad. After adjustment, lock the fixed base 1 to the frame or module transfer mechanism of the PACK assembly equipment to provide a stable installation benchmark for subsequent operations. b. Adjust the initial positions of the front and rear slides to the corresponding initial positions of the product and lock them, so that the clamping mechanism's clamping arm 9 is aligned with the edge of the release paper bottom in the standby state, without interfering with the buffer pad body, thus avoiding collisions and damage to the workpiece when in standby. c. Adjust the airflow rate of the cylinder inlet throttle valve so that the cylinder can achieve gentle clamping in the initial stage of retraction, avoiding the breakage of thin release paper due to a sudden increase in clamping force, and ensuring the gentleness of the clamping action. d. Adjust the preload of the reset spring to the product-compatible clamping force (this can be achieved by adjusting the initial distance between the front and rear slides) to ensure reliable release paper clamping and prevent slippage during paper tearing, while also avoiding excessive rigid clamping pressure that could damage the buffer pad. e. Adjust the cylinder stroke to the corresponding paper-tearing stroke of the product to ensure that the release paper is completely torn off and can be accurately fed into the waste bin of the PACK equipment. Complete all debugging work of the product and enter the initial standby state.

[0035] 2. Initial standby state After debugging, the sliding parts of the sliding mechanism (front slide 4, rear slide 5) maintain their initial relative positions under the preload of the elastic reset mechanism 7 (reset spring). The clamping mechanism (clamping arm 8, clamping arm 9) is in the open state, and the clamping arm 9 is aligned with the bottom edge of the release paper of the product cushioning pad, without contacting the cushioning pad body, waiting for the paper tearing operation command. At this time, the photoelectric sensor 12 is in the standby detection state, does not detect the release paper, and does not trigger the alarm.

[0036] 3. Clamping Phase When the single-power drive mechanism 2 (cylinder) receives the work command and begins to retract, its piston rod pulls the sliding component (front slide 4) of the sliding mechanism through the floating joint 13 to move first. The other set of sliding components (rear slide 5) does not move synchronously under the elastic force of the elastic reset mechanism 7. A relative displacement is generated between the two sets of sliding components, which compresses the elastic reset mechanism 7 (reset spring). This relative displacement causes the clamping arm 8 and the clamping stationary arm 9 of the clamping mechanism to move closer to each other and close. The wedge-shaped fit forms a self-locking effect, which realizes the stable clamping of the product release paper. Because the flow rate of the throttle valve and the spring preload have been adjusted in advance, the clamping action is gentle and the force is moderate. It neither breaks the release paper nor damages the buffer pad body. At this time, the photoelectric sensor 12 detects the release paper, determines that the clamping is successful, and sends a feedback signal to the control system to execute the next paper tearing action.

[0037] 4. Paper tearing stage As the cylinder continues to retract, the elastic reset mechanism 7 (reset spring) is compressed to its limit. Its elastic force pushes the two sets of sliding parts (front slide 4 and rear slide 5) to move smoothly backward along the fixed part 3 (linear guide rail) of the sliding mechanism. The clamping mechanism remains clamped, driving the clamped release paper to move backward synchronously, completely tearing the release paper from the product surface to ensure no residue. At the same time, because the cylinder stroke has been adjusted in advance, after the paper is torn, the front slide 4 and rear slide 5 move to the corresponding position in the waste bin to prepare for subsequent release and material dropping.

[0038] 5. Release and Reset Phase After the paper is torn, the single-power drive mechanism 2 (cylinder) reverses its action. Its piston rod pushes the sliding part (front slide 4) back through the floating joint 13. The elastic reset mechanism 7 (reset spring) releases its elastic potential energy, causing the rear slide 5 to reset. This, in turn, drives the clamping mechanism's moving arm 8 to separate from the clamping stationary arm 9, automatically opening and releasing the release paper. The released release paper waste falls into the waste bin under gravity through the waste bin clearance opening of the fixed base 1, completing the collection. At this time, the photoelectric sensor 12 detects that the release paper has detached from the clamping opening, determines that the paper tearing is successful, and sends a feedback signal to the control system. Finally, the front slide 4 returns to the initial standby position, the rear slide 5 resets synchronously, and the entire mechanism returns to its initial state, waiting for the next work cycle. In subsequent operations, the process of standby-clamping-tearing-releasing-reset can be repeated continuously without repeated debugging.

[0039] If the release paper clamping fails (photoelectric sensor 12 does not detect the release paper), the control system will trigger a shutdown alarm. The operator can check the alignment of the clamping jaws, the spring preload, and the position of the release paper, and restart the equipment after adjustment. If the spring is stuck and the front and rear slides cannot move synchronously, the guide rod 6 and the spring can be disassembled, impurities on the guide rod surface can be cleaned, and grease can be applied to ensure smooth sliding. If there is release paper tear residue, the cylinder stroke and spring preload can be adjusted to ensure sufficient clamping force and that the tearing stroke is in place.
