Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a buffer pad cutting device for new energy battery boxes. Background Technology

[0002] The rapid development of new energy vehicles and energy storage equipment has driven the continuous iteration and widespread application of new energy battery technology. As a core power or energy storage component, the safety and stability of new energy batteries directly affect the overall operational efficiency of the equipment. The battery box, as the load-bearing and protective structure of the battery, plays a crucial role in fixing, cushioning, and protecting the battery. To cope with the impact of vibrations and shocks during transportation and use, buffer pads are usually installed inside the battery box. The elastic deformation of the buffer pads absorbs energy, reducing the impact of external forces on the battery and ensuring the safety of the battery structure.

[0003] After the buffer pads are manufactured, they need to be precisely cut according to the internal dimensions of battery boxes of different specifications. Most existing buffer pad cutting devices are only equipped with basic cutting structures. Although they can achieve basic cutting functions, during the cutting process, buffer pad material debris easily adheres to the surface of the cutting blade. If these debris cannot be removed in time, it will not only lead to problems such as dimensional deviations and uneven cuts in subsequent cutting, but also affect the cutting accuracy and quality.

[0017] Example: Please see Figure 1 - Figure 9 This utility model provides a technical solution: a buffer pad cutting device for a new energy battery box, including a support plate 1, a cutting opening 23 on the support plate 1, an upper operating frame 2 fixedly connected to the upper end of the support plate 1, a cutting blade 5 arranged on the inner side of the upper operating frame 2, a lifting plate 3 fixedly connected to the upper end of the cutting blade 5, a lifting cylinder 4 fixedly connected to the upper end of the upper operating frame 2, the output end of the lifting cylinder 4 penetrating through the upper side wall of the upper operating frame 2 and fixedly connected to the upper end of the lifting plate 3, a dust suction mechanism arranged above the upper operating frame 2, the cutting blade 5 located directly above the cutting opening 23, a pressing mechanism arranged on both the left and right sides of the cutting blade 5, and a bottom cleaning mechanism arranged below the support plate 1; Limiting slides 6 are provided on both the front and rear side walls of the upper operating frame 2. The front and rear ends of the lifting plate 3 extend into the two limiting slides 6 respectively. A limiting slide rod 7 is fixedly connected to the upper inner wall of the limiting slide 6. The lower end of the limiting slide rod 7 passes through the lifting plate 3 and is fixedly connected to the lower inner wall of the limiting slide 6. The clamping mechanism includes a cleaning clamping box 8. The left and right side walls of the cutting blade 5 are provided with chip collection grooves 13. The adjacent ends of the two cleaning clamping boxes 8 extend into the chip collection grooves 13. The lower side wall of the cleaning clamping box 8 is provided with a negative pressure suction port 12, which is located in the chip collection groove 13. A negative pressure is generated in the cleaning clamping box 8 through the suction pipe 18. The debris generated when the cutting blade 5 cuts the buffer pad is sucked into the chip collection groove 13 and collected into the collection box 17 through the negative pressure suction port 12 and the suction pipe 18, so as to realize the real-time cleaning of debris on the surface of the cutting blade 5. The vacuuming mechanism includes a negative pressure pump 16 and a collection box 17. The negative pressure pump 16 is connected to the collection box 17 at its input end. The collection box 17 is connected to two vacuum pipes 18 and 19. The end of the vacuum pipe 19 away from the collection box 17 is connected to the bottom cleaning mechanism. The end of the vacuum pipe 18 away from the collection box 17 passes through the cleaning and pressing box 8 and is connected to the cleaning and pressing box 8. Several sliding rods 9 are fixedly connected to the upper end of the cleaning and pressing box 8. The upper end of the sliding rod 9 passes through the lifting plate 3 and is fixedly connected to the top plate 11. Abutment spring 10 is sleeved on the sliding rod 9. The upper and lower ends of the abutment spring 10 are fixedly connected to the adjacent side walls of the lifting plate 3 and the cleaning and pressing box 8, respectively. The lifting cylinder 4 drives the lifting plate 3 to descend vertically along the limiting slide 6 and the limiting slide rod 7, and drives the cutting blade 5 to move down synchronously. During the descent, the cleaning and pressing boxes 8 on both sides of the cutting blade 5 first contact the buffer pad on the support plate 1. Under the elastic force of the abutment spring 10 and the limiting spring 20, the cleaning and pressing box 8 forms a stable pressing on the buffer pad to prevent the material from shifting during cutting. The bottom cleaning mechanism includes a bottom cleaning box 21 fixed to the lower end of the support plate 1. The bottom cleaning box 21 has two left-right symmetrical infrared detection devices 24 and two left-right symmetrical rotating rollers 25. The rotating rollers 25 are located above the infrared detection devices 24. The suction pipe 29 is connected to the bottom cleaning box 21. A cleaning motor 22 is fixedly connected to the front end of the bottom cleaning box 21. The output end of the cleaning motor 22 passes through the front wall of the bottom cleaning box 21 and is fixedly connected to the front end of one of the rotating rollers 25. The two rotating rollers 25 are driven by gears. Several cleaning brushes 27 and several wiping plates 28 are fixedly connected to the side wall of the rotating rollers 25. The cleaning brushes 27 and several wiping plates 28 are arranged alternately. Cleaning plates 26 are provided on the side of the two rotating rollers 25 away from each other. The front and rear ends of the cleaning plates 26 are fixedly connected to the front and rear inner walls of the bottom cleaning box 21, respectively. The end near the rotating roller 25 has a toothed design; when the lower end of the cutting blade 5 passes through the cutting opening 23 and enters the bottom cleaning box 21, after the infrared detection device 24 detects the cutting blade 5, the cleaning motor 22 drives the two rotating rollers 25 to rotate in opposite directions through gear transmission. The cleaning brush 27 and wiping plate 28 on the rotating roller 25 sweep and wipe the debris. The toothed structure of the cleaning plate 26 further scrapes off the debris attached to the rotating roller 25. At the same time, the negative pressure pump 16 sucks the debris in the bottom cleaning box 21 into the collection box 17 through the suction pipe 19, completing the debris collection under the workbench. Two symmetrically arranged limiting plates 14 are fixedly connected to the inner rear wall of the upper operating frame 2. The limiting plates 14 have through holes 15. The first suction pipe 18 is located in the through hole 15. The first suction pipe 18 is fitted with a limiting spring 20. The two ends of the limiting spring 20 are fixedly connected to the cleaning pressing box 8 and the adjacent side wall of the limiting plate 14, respectively. During the cutting process, the limiting spring 20 is used to limit the first suction pipe 18 to prevent the first suction pipe 18 from falling below the cutting blade 5 and being cut. After the cutting blade 5 rises, the first suction pipe 18 is also limited. The lower end of the cutting blade 5 is V-shaped. By having the tip contact the buffer pad first, the cutting force can be concentrated at the tip position, which significantly reduces the initial cutting resistance, making the cutting easier and the cutting process smoother. Furthermore, the progressive cutting makes the cut neater and smoother, reducing the generation of burrs and debris.

[0018] Working principle: During operation, the lifting cylinder 4 drives the lifting plate 3 to descend vertically along the limiting slide 6 and the limiting slide rod 7, causing the cutting blade 5 to move down synchronously. During the descent, the cleaning and pressing boxes 8 on both sides of the cutting blade 5 first contact the buffer pad on the support plate 1. Under the elastic force of the abutment spring 10 and the limiting spring 20, the cleaning and pressing boxes 8 form a stable pressing on the buffer pad, preventing material displacement during cutting. At the same time, the negative pressure pump 16 starts, generating negative pressure in the cleaning and pressing box 8 through the suction pipe 18. The debris generated when the cutting blade 5 cuts the buffer pad is sucked into the chip collection groove 13, and then through the negative pressure suction port 12 and the suction pipe 18. 8. The debris is collected in the collection box 17, realizing real-time cleaning of the surface of the cutting blade 5. When the lower end of the cutting blade 5 passes through the cutting opening 23 and enters the bottom cleaning box 21, after the infrared detection device 24 detects the cutting blade 5, the cleaning motor 22 drives the two rotating rollers 25 to rotate in opposite directions through gear transmission. The cleaning brush 27 and wiping plate 28 on the rotating rollers 25 sweep and wipe the debris. The toothed structure of the cleaning plate 26 further scrapes off the debris attached to the rotating rollers 25. At the same time, the negative pressure pump 16 sucks the debris in the bottom cleaning box 21 into the collection box 17 through the suction pipe 19, completing the collection of debris under the workbench. After the cutting is completed, the lifting cylinder 4 drives the cutting blade 5 to rise and reset. The cleaning and pressing box 8 moves upward under the action of the abutment spring 10, waiting for the next cutting cycle.
