Description

Technical Field

[0001] The present invention relates to the technical field of adhesive-blocking foam cutting, and in particular to a laser cutting device and process for adhesive-blocking foam for a battery pack of a new energy vehicle. Background Art

[0002] During the production of new energy power batteries, it is necessary to install rubber-blocking foam inside the battery box. The rubber-blocking foam can provide functions such as heat insulation and buffering for the new energy power batteries, prevent the accumulation of internal stress of the battery, thereby reducing the risk of battery cell bulging and extending the battery life. The rubber-blocking foam needs to be cut into appropriate size before being installed in the battery box of the new energy power battery, so a cutting device is required.

[0003] Nowadays, there are many ways to cut the foam of battery pack, such as laser cutting and die cutting. Among them, laser cutting has certain advantages in cutting the foam of battery pack. Through high-temperature laser cutting, the incision is smooth and neat, the cutting speed is fast, there is no contact and the effect is good, which can improve the accuracy of battery packaging, so it is widely used.

[0004] A foam laser cutting machine with publication number CN220093428U in the prior art is provided with a moving structure on the base and corresponding programs are input into two servo motors and a cylinder, so that the laser can move quickly in the up and down, front and back, left and right directions, making the cutting efficiency higher. By providing an adjustment structure in the adjustment box, the distance between the two pulleys can be adjusted according to the size of the cut, so that the two pulleys can better fix the foam and make the cut foam edge smoother.

[0005] Although the above-mentioned device can improve the cutting effect of the rubber-blocking foam, there are still some defects in the actual cutting process. Since the laser cutting table lacks loading and unloading components, during the cutting process of the rubber-blocking foam, workers are required to take out the cut rubber-blocking foam and then place the rubber-blocking foam on the laser cutting table for cutting.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figure 1-9 A laser cutting device for blocking glue foam of a battery pack of a new energy vehicle is shown, comprising a cutting platform 1, and a laser cutting mechanism 2 arranged on the cutting platform 1. The laser cutting mechanism 2 can perform laser cutting according to a specified pattern. It is a mature technology in the prior art and will not be described in detail here. A storage frame 3 is provided at one end of the cutting platform 1, and a discharge port 38 is provided at the bottom end of the storage frame 3 close to the cutting platform 1. The discharge port 38 facilitates the discharge of the blocking glue foam. Both ends of the inner side of the storage frame 3 are fixedly connected with baffles 4 for limiting the position of the foam. A discharge port 5 is provided at the other end of the cutting platform 1, and a discharge mechanism for discharging the finished foam product is provided on the discharge port 5. A material cart 12 is provided in the discharge port 5, and a sorting mechanism for sorting foam products is provided on the material cart 12. An electric telescopic cylinder 6 is fixedly connected between the baffle plate 4 and the inner side of the storage frame 3. An L-shaped plate 7 is fixedly connected to the top of the cutting platform 1 and located on both sides of the storage frame 3. A U-shaped frame 8 is provided on both sides of the discharge port 38. A sliding plate 9 is slidably connected to the inner side of the U-shaped frame 8. Both ends of the sliding plate 9 are fixedly connected to a push plate 10 on one side thereof. A top plate 11 is fixedly connected to the top of the U-shaped frame 8. The output end of the electric telescopic cylinder 6 passes through the storage frame 3 and is fixedly connected to the side wall of the top plate 11. A feeding mechanism for controlling the position of the push plate 10 is provided on the L-shaped plate 7. The feeding mechanism includes a round rod 13, an L-shaped push plate 14 is fixedly connected to the top of the sliding plate 9 and is arranged through the top of the U-shaped frame 8, a plurality of upper springs 15 are fixedly connected between the inner side of the U-shaped frame 8 and the side wall of the sliding plate 9, and the upper springs 15 are convenient for pushing the sliding plate 9 and the push plate 10 to reset, the round rod 13 is slidably connected to the top of the L-shaped push plate 14, and a lower spring 16 is fixedly connected between the outer wall of the round rod 13 and the top of the L-shaped push plate 14, and the lower spring 16 is convenient for pushing the bottom end of the round rod 13 into the groove 21 and moving according to the specified route, and an upper straight groove 17 is opened on the top of the L-shaped plate 7, and the bottom end of the round rod 13 is inserted in On the inner side of the upper straight groove 17, an upper inclined groove 18 is provided at one end of the upper straight groove 17, and a vertical groove 19 is provided at the other end of the upper straight groove 17. A lower straight groove 20 is provided between the upper inclined groove 18 and the vertical groove 19. An inwardly sunken groove 21 is provided at one end of the lower straight groove 20 away from the material storage frame 3. The connection between the groove 21 and the lower straight groove 20 is inclined. The bottom of the round rod 13 is set as a smooth arc surface, which is convenient for the round rod 13 to slide out of the groove 21 more smoothly. A slot 22 is provided on the inner wall of the material storage frame 3 and at a position corresponding to the push plate 10. The setting of the slot 22 avoids obstruction of the push plate 10 from being inserted into both sides of the rubber-blocking foam, which affects the normal feeding of the device; When laser cutting the rubber-blocking foam surface, first stack the rubber-blocking foam to be cut in the storage frame 3 in sequence. At this time, the rubber-blocking foam at the lowest end will fall between the push plates 10, and then control the electric telescopic cylinder 6 to start and drive the top plate 11 and the U-shaped frame 8 to move, thereby driving the push plate 10 and the sliding plate 9 to move, so as to push the foam at the bottom of the storage frame 3 out of the discharge port 38, and at the same time drive the L-shaped push plate 14 and the round rod 13 to slide on the inner side of the upper straight groove 17, and then when the electric telescopic cylinder 6 pushes the rubber-blocking foam into the storage frame 3, the rubber-blocking foam surface in the storage frame 3 will fall under its own gravity, and then the electric telescopic cylinder 6 pushes the rubber-blocking foam to the middle of the cutting platform 1; During this process, the round rod 13 will be driven to slide out of the upper straight groove 17 and into the upper inclined groove 18, thereby driving the L-shaped push plate 14 to gradually slide to both sides, thereby driving the sliding plate 9 and the push plate 10 to slide to both sides and gradually compressing the upper spring 15. Then, when the foam moves to the middle of the cutting platform 1, the push plate 10 will directly move out from both sides of the rubber blocking foam surface, and the round rod 13 will move to the other end of the upper inclined groove 18 and be located above the groove 21. Then, under the elastic force of the lower spring 16, the bottom of the round rod 13 will be pushed into the groove 21, and then the electric telescopic cylinder 6 can be controlled to start resetting, thereby driving the U-shaped frame 8, the L-shaped push plate 14 and the round rod 13 to reset. The step is restricted, so the round rod 13 is driven to slide in the lower straight groove 20 under the thrust of the U-shaped frame 8, and gradually slides out of the groove 21, and at the same time stretches the lower spring 16 upward, and then when the round rod 13 moves to the other end of the lower straight groove 20, the U-shaped frame 8 moves to the initial position, and releases the sliding restriction on the round rod 13, and then pushes the sliding plate 9 and the push plate 10 to reset under the elastic force of the upper spring 15, and drives the L-shaped push plate 14 and the round rod 13 to slide from the vertical groove 19 into the upper straight groove 17, thereby moving the push plate 10 to both sides of the rubber-blocking foam, and repeats this process to realize automatic loading of the device, and finally the laser cutting mechanism 2 can be controlled to start automatic cutting of the rubber-blocking foam.

[0024] In order to ensure that the cut and formed rubber-blocking foam falls neatly onto the material cart 12, the unloading mechanism includes an unloading frame 23, and top grooves 24 are opened on both sides of the top of the unloading port 5. A pair of unloading frames 23 are provided, and the unloading frames 23 are slidably connected to the inner side of the top groove 24. A plurality of support rods 25 are fixedly connected to the side close to the unloading frame 23 at equal distances. Through the setting of the support rods 25, the formed foam can be shielded to prevent the formed foam from moving downward when the formed foam surface is not completely moved to the top of the unloading port 5. The foam cannot be neatly placed on the material cart 12 due to tilting and falling. The top of the unloading frame 23 is rotatably connected to a roller 26. An adjustment plate 27 is fixedly connected to the inner side of the L-shaped plate 7 and the U-shaped frame 8 is far away from the side. The adjustment plate 27 is evenly spaced on the side close to the U-shaped frame 8. The adjustment groove 28 is tilted near the side of the U-shaped frame 8, and the middle of the other side of the adjustment groove 28 is tilted. A pair of return springs 29 are fixedly connected between the inner side of the top groove 24 and the unloading frame 23. After the laser cutting is completed, the electric telescopic cylinder 6 can be controlled to continue to start and repeat the above-mentioned loading operation, and when the U-shaped frame 8 drives the to-be-cut rubber-blocking foam to be moved out of the material storage frame 3, the side end of the U-shaped frame 8 will push the cut rubber-blocking foam on the cutting platform 1 to move, and at the same time, the U-shaped frame 8 drives the adjustment plate 27 to move, so that the cut rubber-blocking foam is moved to the side of the material cart 12, and when the cut and formed foam is moved to the top of the discharge port 5, the adjustment groove 28 on the side wall of the adjustment plate 27 will move to the side of the roller 26, thereby releasing the squeezing of the roller 26, and then pulling the discharge frame 23 to move to both sides under the elastic force of the reset spring 29, so that the support rod 25 is moved out of the discharge port 5, and the roller 26 is pushed into the adjustment groove 28, thereby releasing the restriction on the discharge port 5, and then the cut and formed rubber-blocking foam is removed from the discharge port 5. The waste material on the outside of the rubber-blocking foam will continue to move under the limit of the support rod 25 and will not fall off. Then, with the continued movement of the adjustment plate 27, the roller 26 will continue to slide to both sides along the inclined surface in the middle of the inner side of the adjustment groove 28 (at this time, the slide bar 36 slides to the other end of the transverse groove 33). Then, the roller 26 is gradually squeezed out from the inclined surface on the other side of the adjustment groove 28, and pushes the discharge frame 23 to reset, while stretching the reset spring 29. Then, under the continued push of the U-shaped frame 8, the molded foams are discharged one by one onto the material cart 12, and finally the waste material is discharged from the cutting platform 1.

[0025] In order to prevent the rubber-blocking foam from falling onto the material cart 12 from a too high place, and from swinging during the falling process, so that the material cart 12 cannot be neatly arranged, the sorting mechanism includes a sorting plate 30, which is slidably connected to the inner side of the material cart 12, and a pair of movable grooves 31 are provided on the side wall of the material cart 12. An L-shaped slide plate 32 is fixedly connected to the side wall of the sorting plate 30 through the movable groove 31. The L-shaped slide plate 32 is provided with a plurality of transverse grooves 33 equidistantly on one side of the cutting platform 1, and a lower inclined groove 34 is provided between the plurality of transverse grooves 33. The bottom ends of the lower inclined grooves 34 are provided with inwardly recessed card grooves 35, and the inner side of the card groove 35 and the connection with the lower inclined groove 34 are inclinedly arranged, and the spacing between the transverse grooves 33 is the same as the thickness of the rubber-blocking foam; A slide bar 36 is slidably connected through the side wall of the blanking frame 23, and an extrusion spring 37 is fixedly connected between the side wall of the slide bar 36 and the inner side of the blanking frame 23. The end of the slide bar 36 is set to a smooth arc surface, so that the slide bar 36 can slide out of the inner side of the card slot 35 more smoothly. When the electric telescopic cylinder 6 drives the unloading mechanism to operate, it will drive the unloading frame 23 to move back and forth, and then drive the slide bar 36 in the unloading frame 23 to move back and forth. When the material cart 12 is pushed into the unloading port 5, the slide bar 36 will be inserted into the transverse groove 33, and then when the unloading frame 23 drives the slide bar 36 to move back and forth, it will drive the end of the slide bar 36 to move in the transverse groove 33. Then, when the unloading frame 23 moves to the specified position, the slide bar 36 moves to the side of the card slot 35, and then under the elastic force of the extrusion spring 37, the slide bar 36 is pushed into the card slot 35, and then the unloading frame 23 is pushed to reset under the extrusion of the adjustment plate 27. Since there is a step between the card slot 35 and the transverse groove 33 and is restricted, the slide bar 36 will slide into the lower inclined groove 34 and compress the extrusion spring 37. Since the blanking frame 23 cannot move up and down, the L-shaped slide plate 32 will be pushed downward under the extrusion of the slide bar 36, thereby driving the sorting plate 30 to move downward, and then the slide bar 36 slides out of the lower inclined groove 34 and slides into the transverse groove 33 at the other end. This is repeated. Each time the blanking frame 23 opens and the foam falls onto the sorting plate 30, the sorting plate 30 is driven to move downward a certain distance, which can prevent the foam from falling from a higher distance and ensure that the foam falls neatly on the material cart 12.

[0026] In order to limit the position of the material cart 12, the side walls of the cutting platform 1 and the two sides of the discharge port 5 are rotatably connected with the positioning plates 39 through torsion springs, and the side walls of the cutting platform 1 and the upper parts of the positioning plates 39 are fixedly connected with limit blocks 40 for limiting the flipping position of the positioning plates 39. Through the setting of the limit blocks 40, the flipping position of the positioning plates 39 can be limited. When the material cart 12 is pushed into the discharge port 5, the two positioning plates 39 are first pushed downward to flip downward, and the torsion springs are compressed, thereby releasing the obstruction at the discharge port 5. The material cart 12 can be pushed into the discharge port 5, and then the positioning plate 39 can be loosened. Subsequently, the positioning plate 39 is pushed to flip and reset under the elastic force of the torsion spring, and is stuck on the side wall of the material cart 12 to limit the movement of the material cart 12. Then the L-shaped slide plate 32 can be pulled upward to drive the sorting plate 30 to slide upward. At this time, the slide bar 36 can be pressed to compress the extrusion spring 37 to avoid affecting the upward sliding of the L-shaped slide plate 32. Then the sorting plate 30 is pushed to the top, and the slide bar 36 can be loosened to ensure that the slide bar 36 is inserted into the horizontal groove 33.

[0027] A laser cutting and assembly process for a new energy vehicle battery pack adhesive foam comprises the following steps: Step 1: Loading: First, stack the rubber-blocking foam to be cut in the material storage frame 3 in sequence, and then start the electric telescopic cylinder 6 to drive the sliding plate 9 and the pushing plate 10 to move, so as to push the rubber-blocking foam at the bottom of the material storage frame 3 to the middle of the cutting platform 1; Step 2: Reset. Then the electric telescopic cylinder 6 starts to reset, and the pushing plate 10 is driven to reset through the feeding mechanism, and moves to both sides of the bottom rubber-blocking foam in the storage frame 3; Step 3: Cutting, then the laser cutting mechanism 2 can be controlled to start laser cutting of the rubber blocking foam; Step 4, unloading. After the laser cutting is completed, the electric telescopic cylinder 6 can be controlled to start, and the operation in step 1 can be repeated. When the electric telescopic cylinder 6 drives the U-shaped frame 8 to move, it will push the cut rubber-blocking foam on the cutting platform 1 to move. Then, when the cut rubber-blocking foam moves to the top of the unloading port 5, it will fall onto the material cart 12 through the unloading mechanism. At the same time, the waste around the cut product will be discharged from the outside of the unloading port 5 and fall from the cutting platform 1, thereby realizing automatic loading and unloading of the device.
