Follow-up cutting and inserting mechanism and pole piece and diaphragm compounding equipment

Abstract

According to the follow-up cutting and inserting piece mechanism and the pole piece diaphragm composite equipment, after one-time inserting piece is completed, a mounting base drives a cutter and a traction assembly to integrally retreat in the direction away from an inserting piece station, and in the process, the traction assembly continues to convey materials in the direction close to the inserting piece station, so that the materials are fed at a constant speed all the time. After the mounting base retreats by a certain distance (smaller than the required pole piece width), the mounting base drives the cutter and the traction assembly to integrally move towards the direction close to the piece inserting station, when the moving speed of the mounting base is consistent with the moving speed of the material, the traction assembly stops, and the cutting driving piece drives the cutter to cut off the material; and finally, the cut-off materials are obtained through the sheet inserting station, and sheet inserting is conducted. The moving distance of the mounting base is small, the mechanism size is reduced, and the movement distance is reduced, so that the sheet inserting speed is increased; and the materials move towards the direction close to the sheet inserting station at a constant speed all the time, pause is not needed, and efficiency is improved.

[0001] The invention relates to the field of battery pole pieces, and in particular to a follow-up cutting and inserting mechanism and pole piece diaphragm composite equipment. Background Art

[0002] During the battery production process, the pole pieces need to be cut so that the cut pole pieces can adapt to batteries of different design structures and specifications. In the prior art, the pole pieces are cut in a fixed manner. After being cut by a cutter, the pole pieces are transported to the inserting station by the pole piece clamps.

DETAILED DESCRIPTION

[0041] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work belong to the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. For example, fixed connection / fixed installation can be selected according to the needs of screw connection, bolt connection, pin connection, key connection, bonding, mortise and tenon connection, welding, riveting and other methods. For example, detachable connection can be selected according to the needs of screw connection, bolt connection, threaded connection, snap connection, mortise and tenon connection, Velcro connection and other methods. The various technical features in the invention can be combined interactively without conflicting with each other.

[0042] See also Figure 1-4The preferred embodiment of the present invention provides a follow-up cutting insert mechanism 1, including a translation component 2, a cutting component 3, and a traction component 4; the translation component 2 includes a moving part 21 and a fixed part 22, the moving part 21 is slidably connected to the fixed part 22, the sliding direction of the moving part 21 is the feeding direction, and the moving part 21 includes a mounting seat 211; the cutting component 3 includes a cutting drive component 31 and a cutter 32, the cutting drive component 31 is used to drive the cutter 32 to cut the material, the cutting drive component 31 is installed on the fixed part 22, and the cutter 32 is connected to the mounting seat 211; the traction component 4 is connected to the mounting seat 211, and the traction component 4 is used to continue to feed forward during the retreat of the moving part 21. Since the cutter 32 and the traction assembly 4 are connected to the mounting seat 211, in the process of conveying the material to the inserting station, the mounting seat 211 drives the cutter 32 and the traction assembly 4 to move as a whole. After completing one insertion, the mounting seat 211 drives the cutter 32 and the traction assembly 4 to retreat as a whole in the direction away from the inserting station. In this process, the traction assembly 4 continues to convey the material in the direction close to the inserting station, and the difference between the speed of the traction assembly 4 conveying the material and the retreat speed of the mounting seat 211 is equal to the moving speed of the material itself, so that the material is always in a uniform feeding state. After the mounting seat 211 retreats a certain distance (less than the required pole piece width), the mounting seat 211 drives the cutter 32 and the traction assembly 4 to move as a whole in the direction close to the inserting station. When the moving speed of the mounting seat 211 is consistent with the moving speed of the material itself, the traction assembly 4 stops. At this time, the moving speed of the cutter 32 is consistent with the moving speed of the material itself, and the two are relatively stationary. The cutting drive 31 drives the cutter 32 to cut the material, and finally the inserting station obtains the cut material and inserts the sheet. During the entire process, the moving distance of the mounting seat 211 is less than the required pole piece width, which saves the space required for the action and is beneficial to reducing the size of the mechanism. The reduced action distance is beneficial to increasing the insertion speed; and the material moves at a uniform speed in the direction close to the insertion station without stopping, thereby improving efficiency.

[0043] In this embodiment, the translation assembly 2 also includes a translation drive member 23, the stator of the translation drive member 23 is fixedly connected to the fixed member 22, the mover of the translation drive member 23 is fixedly connected to the moving member 21, and the moving member 21 is slidably set on the fixed member 22 through the translation drive member 23. Specifically, the translation drive member 23 is a linear motor. The linear motor does not require additional devices to convert rotational motion into linear motion. It has a simple structure, which is conducive to reducing weight and volume. The linear motor can realize direct transmission, eliminate various positioning errors caused by intermediate links, and has high positioning accuracy.

[0044] In other embodiments, the translation drive member may also be a cylinder, which has a large load, can adapt to applications with high torque output, and has rapid movement and quick response.

[0045] See also Figure 1 and Figure 5The cutting assembly 3 further includes a first cutting guide rail 33, a lifting plate 39, a second cutting guide rail 34 and a translation plate 35. The first cutting guide rail 33 is mounted on the fixing member 22 in a direction perpendicular to the feeding direction. The cutting driving member 31 is used to drive the lifting plate 39 to slide along the first cutting guide rail 33. The second cutting guide rail 34 is mounted on the lifting plate 39 in a direction parallel to the feeding direction. The translation plate 35 is slidably connected to the second cutting guide rail 34. A connecting hole 212 is provided on the mounting seat 211. A connecting rod 351 is connected between the translation plate 35 and the cutter 32. The connecting rod 351 is passed through the connecting hole 212. The cutting driving member 31 drives the lifting plate 39 to slide along the first cutting guide rail 33. The lifting plate 39 drives the translation plate 35 to move in a direction perpendicular to the feeding direction, so that the cutter 32 moves in a direction perpendicular to the feeding direction, thereby completing the cutting of the material. The connecting rod 351 can abut against the inner wall of the connecting hole 212, and the mounting seat 211 can drive the connecting rod 351 to move together. The connecting rod 351 drives the translation plate 35 to move along the second cutting guide rail 34, so that the cutter 32 can move in the feeding direction. The cutter 32 can move in two directions at the same time, so that the cutter 32 can complete the cutting of the material during the uniform feeding process of the material.

[0046] See also Figure 3 In this embodiment, a drag chain 25 is connected between the mounting seat 211 and the fixing member 22, and the drag chain 25 is used to store, pull and protect the pipeline.

[0047] See also Figure 5 and Figure 6 The cutting drive component 31 includes a cutting motor 311 and a crankshaft 312. The rotating shaft of the cutting motor 311 is connected to the crankshaft 312, and the crankshaft 312 is connected to the lifting plate 39. The crankshaft 312 can convert the rotation of the cutting motor 311 into the linear motion of the lifting plate 39. In this mechanism, the cutter 32 moves a small distance during cutting but the cutting frequency is high. Therefore, the lifting plate 39 is required to perform a linear motion with a high frequency but a small reciprocating distance. The characteristics of the crankshaft 312 are suitable for such requirements.

[0048] Specifically, the crankshaft 312 includes a first drive shaft 313, a drive block 314 and a second drive shaft 315. The length directions of the first drive shaft 313 and the second drive shaft 315 are the same as the feeding direction.

One end of the second drive shaft 315 is rotatably connected to the drive block 314, and the other end is fixedly connected to the lifting plate 39. The first drive shaft 313 is driven to rotate by the rotating shaft of the cutting motor 311, and the first drive shaft 313 drives the drive block 314 to rotate, so that the end of the second drive shaft 315 connected to the drive block 314 rotates, and the other end of the second drive shaft 315 drives the lifting plate 39 to move up and down.

[0049] See also Figure 1 and Figure 2 The follow-up cutting insert mechanism 1 also includes a pressure plate assembly 5, which is used to fix the cut material; the pressure plate assembly 5 includes a first pressure plate 51, a second pressure plate 52 and a guide plate 64, the first pressure plate 51 and the second pressure plate 52 are arranged opposite to each other, and the first pressure plate 51 is connected to the translation plate 35 through a bracket 511, and the second pressure plate 52 is connected to the mounting seat 211, and one side of the guide plate 64 is located between the first pressure plate 51 and the second pressure plate 52, and the other side is bent toward the direction close to the cutter 32. During the cutting process of the cutter 32, driven by the translation plate 35, the first pressure plate 51 and the cutter 32 move synchronously, ensuring that the first pressure plate 51 and the second pressure plate 52 can clamp the cut material at the first time of cutting the material to prevent the cut material from falling. The guide plate 64 can guide the cut material to ensure that the cut material enters between the first pressure plate 51 and the second pressure plate 52.

[0050] A tension spring 512 is connected between the bracket 511 and the mounting seat 211; a pressure plate slider 513 is connected to the bracket 511, and a pressure plate guide rail 514 is installed on the mounting seat 211. The pressure plate slider 513 is slidably connected to the pressure plate guide rail 514, and the pressure plate guide rail 514 is arranged in a direction perpendicular to the feeding direction. During the cutting process of the cutter 32, the pressure plate guide rail 514 can guide the movement of the first pressure plate 51. When the bracket 511 is raised, the end of the tension spring 512 is pulled apart, and the tension spring 512 will try to pull its end back, so that the first pressure plate 51 and the second pressure plate 52 can be clamped together.

[0051] See also Figure 7 and Figure 8 The follow-up cutting insert mechanism 1 further includes a dust removal assembly 6, which is located between the cutter 32 and the pressure plate assembly 5; the dust removal assembly 6 includes a dust removal box 61 and a dust removal cover 62, the opening of the dust removal box 61 faces the cutter 32, the dust removal cover 62 is arranged at the opening of the dust removal box 61, the dust removal box 61 is mounted on the mounting seat 211, and the dust removal cover 62 is provided with a dust suction hole 621, which is connected to the inside of the dust removal box 61. Specifically, the dust removal box 61 is mounted on the mounting seat 211, and the dust removal assembly 6 can absorb dust on the material during the material conveying process.

[0052] See also Figure 3 In this embodiment, the dust removal component 6 also includes a dust removal pipe 63, which is connected to the inside of the dust removal box 61. By connecting the dust removal pipe 63 to a negative pressure source, a negative pressure can be formed on the surface of the dust suction hole 621, thereby collecting the dust on the material into the dust removal box 61.

[0053] See also Figure 2The cutting assembly 3 also includes a cutting guide rod 36, which is installed on the mounting seat 211 in a direction perpendicular to the feeding direction. The cutter 32 is connected to the cutting guide rod 36 through a connecting block 37, and the connecting block 37 is slidably connected to the cutting guide rod 36. During the cutting process of the cutter 32, the connecting block 37 can drive the cutter 32 to slide along the cutting guide rod 36, thereby guiding the movement of the cutter 32.

[0054] In this embodiment, one end of the connecting rod 351 is connected to the translation plate 35 , and the other end is connected to the connecting block 37 . When the translation plate 35 drives the connecting rod 351 to move, the connecting block 37 drives the cutter 32 to move.

[0055] See also Figure 2 , a dust removal pressure plate 38 is provided on the connecting block 37, see Figure 7 The dust removal plate 38 is connected to the dust removal cover 62. A dust removal guide rod 65 is provided in the dust removal box 61. The length direction of the dust removal guide rod 65 is perpendicular to the feeding direction. The dust removal cover 62 is slidably connected to the dust removal guide rod 65. Figure 8 When the cutter 32 is cutting, the connecting block 37 drives the dust cover 62 to move downward along the dust guide rod 65 to avoid the cutter 32. Fig. 9 After cutting is completed, the cutter 32 is lifted up, and the dust removal cover 62 rises along the dust removal guide rod 65 and is flush with the second pressing plate 52, so that the material passes smoothly.

[0056] See also Figure 2 and Figure 7 The cutting guide rod 36 is sleeved with a first coil spring 361, which is located below the connecting block 37. The first coil spring 361 can play a buffering role when the connecting block 37 moves, so that the cutter 32 can cut the material more gently. The dust removal guide rod 65 is sleeved with a second coil spring 651, which is located below the dust removal cover 62. The second coil spring 651 can play a buffering role when the dust removal cover 62 moves, and transmits the buffering force to the cutter 32, further improving the softness of the cutter 32 in cutting the material.

[0058] The traction assembly 4 also includes a seam adjustment drive 44 and a seam adjustment guide 47. The seam adjustment drive 44 is mounted on the mounting seat 211. The seam adjustment drive 44 is used to drive the driven roller 42 to move toward or away from the active roller 41 to adjust the distance between the driven roller 42 and the active roller 41. The seam adjustment guide 47 includes a linear bearing 451 and a seam adjustment guide rod 45. The seam adjustment guide rod 45 is slidably connected to the linear bearing 451. The linear bearing 451 is mounted on the mounting seat 211. The length direction of the seam adjustment guide rod 45 is perpendicular to the feeding direction.
