Description

Technical Field

[0001] This invention belongs to the field of membrane material cutting technology, and particularly relates to a precision laser cutting machine for membrane materials. Background Technology

[0002] In the field of film processing in intelligent heat treatment production lines, especially in the precision cutting process of adhesive films for new energy batteries, laser cutting technology has been widely used in the forming and processing of adhesive films due to its advantages of high cutting efficiency and smooth cut edges.

[0003] However, existing laser cutting equipment mostly uses a flat cutting method, which cannot simulate the actual assembly shape, bending angle, and bonding state of the adhesive film on new energy batteries. This leads to problems such as dimensional deviations, edge wrinkling, and poor bonding when the cut adhesive film is bonded to the corners and curved surfaces of new energy batteries, requiring secondary trimming, which increases processing costs and assembly losses. At the same time, the cutting posture of existing equipment is fixed, and it is impossible to flexibly adjust the bending angle and bonding angle at the corners of the adhesive film. This makes it difficult to adapt to the processing needs of adhesive films of different specifications and shapes of new energy batteries, resulting in poor versatility and requiring frequent replacement of special fixtures or equipment, increasing the equipment investment of enterprises. In addition, existing equipment mostly uses a single pressing or adsorption method to position and fix the adhesive film, which is not stable enough. The adhesive film is prone to slippage and wrinkles during the spreading, bending, and cutting process, resulting in cutting deviations and affecting the consistency of cutting quality. This cannot meet the automation and high-precision production requirements of intelligent heat treatment production lines, thus restricting the processing efficiency and product qualification rate of the production line.

[0004] To address these issues, we propose a precision laser cutting machine for membrane materials. Summary of the Invention

A round rod is rotatably connected to the inner wall of the U-plate, and a second motor is fixedly connected to the side wall of the U-plate. The output end of the second motor passes through the side wall of the U-plate and is fixedly connected to one end of the round rod.

[0009] Preferably, each of the round rods has a connecting plate fixedly connected to its wall, and each of the connecting plates has a first electric telescopic rod fixedly connected to its side wall, with a fixing plate fixedly connected to the telescopic end of each of the first electric telescopic rods.

[0010] Preferably, an air pump is fixedly connected to the top sidewall of the mounting shell. The air inlet of the air pump extends inward through the sidewall of the mounting shell. The sidewall of the mounting shell is provided with multiple adsorption holes. The adsorption holes communicate with the internal space of the mounting shell, and the adsorption holes and the fixing plate are located on the same side of the mounting shell.

[0011] Preferably, the corner angle adjustment assembly includes a fixed cylinder fixedly connected to the top side wall of the base plate, an annular electric slide rail fixedly connected to the inner top wall of the fixed cylinder, two annular sliding plates slidably connected to the top side wall of the annular electric slide rail, and two clamping plates fixedly connected to the top side wall of each annular sliding plate.

[0012] Preferably, the top side wall of the fixed cylinder is provided with a hinge, and guide plates are fixedly connected to both sides of the hinge. The side walls of the two clamps at the top of the annular slide plate abut against the side walls of the corresponding guide plates.

[0013] Preferably, the auxiliary simulation component includes a third groove formed in the side wall of the base plate, a third electric slide rail fixedly connected to the inner wall of the third groove, a third sliding plate slidably connected to the side wall of the third electric slide rail, a bent rod fixedly connected to the top side wall of the third sliding plate, a second electric telescopic rod fixedly connected to one end of the bent rod, an L-plate fixedly connected to the telescopic end of the second electric telescopic rod, a third motor fixedly connected to the top side wall of the L-plate, a mounting rod rotatably connected to the bottom side wall of the L-plate, the output end of the third motor passing through the side wall of the L-plate and fixedly connected to one end of the mounting rod, a plurality of third electric telescopic rods fixedly connected to the rod wall of the mounting rod, and a locking block fixedly connected to the telescopic end of each of the third electric telescopic rods.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By simulating the coordinated operation of the fixing component, corner angle adjustment component, and auxiliary simulation component, the actual assembly shape, bending angle, and bonding state of the adhesive film on the new energy battery can be completely replicated. This allows the adhesive film cutting process to be carried out under real-world usage conditions, effectively avoiding problems such as dimensional deviations, edge wrinkling, and poor bonding that occur when the adhesive film is cut flat and then bonded to the corners and curved surfaces of the new energy battery in existing technologies. This significantly improves the accuracy of the adhesive film cutting, ensuring that the cut adhesive film can be directly adapted to the assembly of the new energy battery without secondary trimming, reducing processing costs and assembly losses. The corner angle adjustment component allows for flexible adjustment of the bending angle at the corners of the adhesive film, and the simulated fixing component allows for adjustment of the tilt of the mounting shell. The angled design, combined with the position adjustment of the auxiliary simulation components, can adapt to the different positions and angles of adhesive film cutting for new energy batteries. No special fixtures or equipment need to be replaced, significantly expanding the equipment's applicability. It employs a dual fixing method of negative pressure adsorption and mechanical clamping. A negative pressure is created in the adsorption holes on the mounting shell by an air pump, tightly adsorbing the adhesive film onto the surface of the mounting shell. Simultaneously, the first electric telescopic rod drives the fixing plate to perform segmented clamping and positioning of the adhesive film. This dual fixing structure works together to ensure that the adhesive film has no gaps, wrinkles, or slippage with the simulated bonding surface throughout the entire process of spreading, bending, and cutting. This effectively avoids cutting deviations caused by adhesive film displacement, further improving the consistency of cutting quality. Attached Figure Description

[0027] The operating principle of the present invention is now described as follows: In this invention, when the adhesive film in the membrane material needs to be laser-cut, the annular electric slide rail 42 in the corner angle adjustment component 4 is first started. The annular electric slide rail 42 drives the two annular slide plates 43 to move relative to each other. The annular slide plates 43 drive the corresponding clamping plates 44 to move synchronously. The clamping plates 44 push the corresponding guide plates 46 to deflect around the hinge 45, thereby adjusting the included angle formed between the two guide plates 46 so that the included angle is consistent with the actual use angle at the corner of the outer wall of the new energy battery. After the angle adjustment is completed, the annular electric slide rail 42 is stopped. Subsequently, the first motor 38 in the simulated fixing component 3 is started, the first motor 38 drives the support rod 39 to rotate, and the support rod 39 drives the mounting shell 310 to rotate synchronously, so that the tilt angle of the mounting shell 310 matches the tilt angle of the guide plate 46. After the angle is adjusted to the correct position, the first motor 38 is turned off. Then, the first electric slide rail 32 and the second electric slide rail 36 are started, driving the first sliding plate 33 and the second sliding plate 37 to move in linkage, so that the side wall of the mounting shell 310 is tightly attached to the side wall of the corresponding guide plate 46, thereby completely simulating the assembly form and bending posture of the adhesive film when it is actually used on the outer wall of the new energy battery. Then, the take-up drum wrapped with adhesive film is placed outside the locking block 510 of the auxiliary simulation component 5. Multiple third electric telescopic rods 59 are controlled to extend synchronously, so that the locking block 510 is tightened and fixed from the inner wall of the take-up drum. The second electric telescopic rod 55 is controlled to start, driving the take-up drum to move towards the mounting shell 310, pulling the free end of the adhesive film to the outer wall surface of the mounting shell 310. At the same time, the third motor 57 is controlled to start, and the third motor 57 drives the mounting rod 58 and the take-up drum to rotate, so as to realize the automatic unwinding and smooth spreading of the adhesive film. At the same time, the air pump 318 is started, and the air pump 318 extracts the air inside the mounting shell 310, so that the adsorption hole 319 forms a negative pressure adsorption force to initially position and adsorb the end of the adhesive film; then the second motor 314 at the corresponding position is started, and the second motor 314 drives the round rod 313 and the connecting plate 315 to rotate 180°, and then the first electric telescopic rod 316 is extended, so that the fixing plate 317 mechanically presses and fixes the end of the adhesive film. After the end is fixed, the third electric slide rail 52 is started, which drives the take-up drum to move along the set path. With the continuous unwinding action of the third motor 57, the adhesive film is continuously and smoothly unfolded and tightly adhered to the outer wall surface of the mounting shell 310. In the area where the adhesive film adheres to the mounting shell 310, the second motor 314 and the first electric telescopic rod 316 at the corresponding positions are controlled in sequence to make the fixing plate 317 press and position the adhesive film in sections. With the negative pressure adsorption effect of the adsorption hole 319, the adhesive film is ensured to adhere to the outer wall of the mounting shell 310 without gaps, wrinkles, or slippage. After the adhesive film passes through the area of ​​the guide plate 46 and adheres to the outer wall of the mounting shell 310 on the other side, repeat the above adsorption and pressing steps to make the adhesive film completely adhere to the mounting shell 310 and guide plate 46 combination structure that simulates the shape of a new energy battery. After the adhesive film is spread in place, control the third electric slide rail 52 to stop moving to complete the shape simulation and positioning fixation of the adhesive film in actual use. Finally, the cutting assembly 6 is activated, controlling the third electric slide rail 52 to drive the fourth slide plate 61 to move, moving the laser cutting gun 66 to one side of the cutting station; controlling the fourth electric telescopic rod 65 to move, so that the laser cutting gun 66 is fed to the appropriate cutting height; then controlling the fifth electric slide rail 63 to drive the fifth slide plate 64 to move up and down, in conjunction with the laser output of the laser cutting gun 66, to perform high-precision laser cutting on the adhesive film in a simulated bending and bonding state; By simulating the actual assembly angle, bending shape, and bonding state of the adhesive film on new energy batteries, the positioning and laser cutting of the adhesive film under real-world operating conditions are achieved. This improves the intuitiveness of the cutting position and the processing accuracy, enhances the intelligence and automation level of the adhesive film laser cutting, and is suitable for continuous operation in intelligent heat treatment production lines.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
