Description

Technical Field

[0001] The invention relates to the technical field of friction grooves, and in particular to a carbon fiber reinforced paper-based friction groove system and method. Background Art

[0002] Carbon fiber reinforced paper-based friction plates (hereinafter referred to as "paper-based friction plates" or "friction plates") are widely used in vehicle parts such as hydraulic transmissions, clutches, and wet brakes for engineering machinery. They are mainly composed of steel linings and friction paper bases on both sides of the steel linings. The friction paper bases are bonded to both sides of the steel linings to increase the friction coefficient. Generally speaking, the friction paper base components of most wet friction clutch plates are similar. Typical components include celluloid fibers, resins, and adhesives, but the use of special fillers, fibers, and other ingredients creates differences between different friction paper bases. Despite these differences, the advancement of friction paper bases lies in their porosity, compressibility, permeability (ability to breathe oil), and cost-effectiveness.

[0003] Grooving is a crucial step in the manufacturing of carbon fiber-reinforced paper-based friction plates. Grooving primarily involves cutting grooves into the friction paper substrate to facilitate the formation of cooling oil channels. Currently, Chinese vehicle friction plate manufacturers use traditional equipment, such as planers or milling machines, to create straight grooves (waffle grooves) in these plates. This process results in high scrap rates due to the tendency for the edges of the grooves to break. Furthermore, the resulting oil grooves do not achieve the desired effect, and it is difficult to maintain consistent spacing between the grooves.

[0004] Prior art 1 (CN201760815U) discloses a friction plate straight groove processing device, which mainly uses a grinder to install a milling wheel to process the friction plate straight groove. By installing a certain number of grinding wheels, different numbers of straight oil grooves can be processed, and the problem of edge collapse of the straight groove can be avoided. However, during the processing, the machine must be stopped after each oil groove is processed, and the product angle must be manually rotated, which is time-consuming and labor-intensive, and the processing efficiency is low. Moreover, after the workbench processes each friction plate, the processing time cycle is about 5 to 10 minutes, and workers need to repeat unloading and loading every 5 to 10 minutes, which is labor-intensive, inefficient, and labor-intensive.

[0005] Prior art 2 (CN201760643U) discloses a friction plate mesh oil groove processing device. It uses a mutually meshing torque input gear, an additional gear set, a torque transfer gear, and a reduction gear box to drive the rotation of the rotating disk. The friction plate is mounted on a workpiece fixed disk. The workpiece fixed disk can rotate with the rotation of the rotating disk. Therefore, during the groove processing of the friction plate, the workpiece fixed disk can be automatically rotated to realize the groove processing of the mesh oil groove. However, during the processing of this device, after each friction plate is processed, manual unloading and loading are still required. This is labor-intensive, inefficient, and labor-intensive.

[0006] Therefore, it is necessary to provide a carbon fiber reinforced paper-based friction sheet grooving system that can automatically load and unload materials, which can save labor costs, improve grooving processing efficiency, and ensure product consistency. Summary of the Invention

[0007] In order to solve the problems of low processing efficiency and inability of the oil groove processing related dimensional indicators to meet the requirements of the existing technology, the purpose of the present invention is to provide a fully automatic carbon fiber reinforced paper-based friction plate grooving system and method, which can liberate labor, save labor costs, improve grooving processing efficiency, and ensure product consistency.

[0083] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0084] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0085] In the following embodiments of the present invention, the friction plate is a carbon fiber reinforced paper-based friction plate, hereinafter referred to as "paper-based friction plate" or "friction plate".

[0086] In a first aspect, the present invention designs a gripper specifically for friction plates. During early development, existing grippers using negative pressure suction were designed, but this approach struggled to maintain a secure grip and was prone to material dropout. This dropout produced flying flakes, which could cause the friction plate to fly nearly a meter away, potentially causing safety hazards. Existing grippers using negative pressure suction also struggled to maintain a stable grip and exhibited poor reliability.

[0087] This is primarily due to the unique structure of the friction plate. It consists of a steel plate and two paper sheets, one on each side. The paper sheets have a certain porosity, making negative pressure suction difficult to achieve stable adsorption and prone to air leakage, resulting in poor reliability. Therefore, a specialized gripping mechanism for the friction plate—magnetic adsorption—is required. The magnetic attraction force matches the friction plate's gravity, the spacing of the magnetic beads matches the plate's dimensions, and the paper thickness ranges from 0.4 to 1.2 mm. The key factors for robotic gripping are shown in Table 1.

[0088] Table 1 Key factors of robot grasping

[0089]

[0090] As can be seen from Table 1, the key factors for the manipulator to successfully grasp the friction plate include the outer diameter and weight of the friction plate, the position of the manipulator's grasp, and the suction force. Due to the paper-like nature of the friction plate, a suitable manipulator must be designed to stably grasp the friction plate.

[0091] In addition to conducting suction tests, several other factors also determine the success or failure of the "manipulator" in grasping the friction plate. First, the suction area between the friction plate and the electromagnet's holding surface (diameter) should be greater than or equal to the diameter of the magnetic bead. Tests have shown that to ensure that the magnetic beads can maximize their maximum suction force, the magnetic beads must be finely adjusted on the adjustment claws (the claws used to connect and fix the magnetic beads) to ensure that the suction area between the friction plate being sucked and the electromagnet's holding surface (diameter) is greater than or equal to the diameter of the magnetic bead. Second, the surface where the three claws fit together with the magnetic bead must be adjusted. To ensure that the magnetic bead's holding surface and the adjustment claws are fully aligned, the surface where the three claws fit together with the magnetic bead must maintain a flatness of less than 0.01mm and a parallelism of less than 0.005. These tolerances require precision machining and heat treatment to achieve. Third, the rigidity of the adjustment claws must ensure stable grasping, without any up and down shaking.

[0092] Therefore, a robot structure specifically designed for friction plate processing was developed based on the characteristics of friction plates. Through extensive process validation, the present invention's friction plate gripping system, utilizing a robot (connected to a suction cup electromagnet), achieves optimal gripping performance while retaining sufficient suction margin to accommodate friction plates of varying diameters and weights. This addresses the issue of vacuum suction cups, commonly used in the automation industry, which often suffer from poor reliability in gripping paper-based friction plates.

[0093] The following specifically describes the fully automatic carbon fiber reinforced paper-based friction plate groove system containing the robot structure.

[0094] The first aspect of the present invention

[0095] See also Figure 1A first aspect of the present invention provides a grooving system for a carbon fiber-reinforced paper-based friction plate, comprising a grooving device 1, a conveying device 2, a loading device 3, a grooving indexing device 4, and an unloading device 5. Through the coordinated operation of these components, the first aspect of the present invention enables automatic loading, automatic grooving, rotational indexing, regrooving, and automatic unloading of the paper-based friction plate, thereby resolving current issues such as low precision, poor grooving consistency, and low grooving efficiency in batch grooving of friction plates.

[0096] In some embodiments of the present invention, the conveying device 2 includes a transfer platform 21 for carrying the friction plate and is configured to transport the transfer platform 21 to the loading station 71 , the notching and indexing station 72 , or the unloading station 73 .

[0097] See also Figure 1 and Figure 10 In some preferred embodiments of the present invention, the grooving system further comprises a workbench 7, which is divided into a plurality of workstations: a loading station 71, a grooving indexing station 72, and an unloading station 73. The conveying device 2 comprises a conveying slide 22 and a second drive assembly. The conveying slide 22 is slidably disposed on the workbench 7; the second drive assembly is disposed on the workbench 7 and is capable of driving the conveying slide 22 to reciprocate, thereby transporting the transfer platform 21 to the loading station 71, the grooving indexing station 72, or the unloading station 73, respectively.

[0098] In order to improve efficiency, two transfer platforms 21 are provided. Of course, the number of transfer platforms can also be increased as needed. In some preferred embodiments of the present invention, the transfer platform 21 includes a first transfer platform 211 and a second transfer platform 212, which are fixedly connected to each other; that is, the first transfer platform 211 and the second transfer platform 212 are both fixed on the conveyor slide 22. As the conveyor slide 22 moves, the first transfer platform 211 can reciprocate to the loading station 71 or the groove indexing station 72, and the second transfer platform 212 can reciprocate to the groove indexing station 72 or the unloading station 73. Thus, through the reciprocating movement of the two transfer platforms 21, efficiency is improved while achieving batch production of grooves.

[0099] In some embodiments of the present invention, the loading device 3 is configured at the loading station 71. The loading device 3 is mainly used to transfer the friction plate located in the silo to the first transfer platform 211 to achieve automatic loading. The loading device 3 includes a first grabbing and transporting assembly 31 and a first driving assembly 32. The first grabbing and transporting assembly 31 is used to grab the friction plate 8. The first driving assembly 32 is used to drive the first grabbing and transporting assembly 31 to move and transfer the friction plate 8 to the transfer platform 21. During specific use, first, the first driving assembly 32 drives the first grabbing and transporting assembly 31 to move to the silo. Then, the mechanical claw of the first grabbing and transporting assembly 31 moves downward to absorb and grab the friction plate. After that, the first driving assembly 32 drives the first grabbing and transporting assembly 31 to move to the loading station. The mechanical claw of the first grabbing and transporting assembly 31 moves downward to place the friction plate on the first transfer platform 211 to achieve automatic loading.

[0100] In some embodiments of the present invention, the groove indexing device 4 is disposed at the groove indexing station 72. The groove indexing device 4 includes a second grabbing and handling assembly 41. The second grabbing and handling assembly 41 is used to grab the friction plate 8 on the transfer platform 21, rotate it, and then place the rotated friction plate 8 on the transfer platform 21. During specific use, first, the mechanical claw of the second grabbing and handling assembly 41 moves downward, then suction-grabs the friction plate, and then rotates the mechanical claw to adjust the configuration angle of the friction plate relative to the second transfer platform 212. When the second transfer platform 212 moves to the groove indexing station, the mechanical claw of the second grabbing and handling assembly 41 moves downward to place the friction plate on the second transfer platform 212, thereby achieving automatic groove indexing.

[0101] In some embodiments of the present invention, the unloading device 5 is disposed at the unloading station 73. The unloading device 5 is primarily used to transfer the friction plate located on the second transfer platform 212 out of the unloading station 73, thereby achieving automatic unloading. The unloading device 5 includes a third grabbing and handling assembly 51 and a third drive assembly 52. ​​The third grabbing and handling assembly 51 is used to grab the friction plate 8 on the transfer platform 21. The third drive assembly 52 is used to drive the third grabbing and handling assembly 51 to move the friction plate 8. During operation, the mechanical claw of the third grabbing and handling assembly 51 first moves downward to absorb and grab the friction plate located on the second transfer platform 212. Then, the third drive assembly 52 drives the third grabbing and handling assembly 51 out of the unloading station 73, thereby achieving automatic unloading.

[0102] See also Figure 1 and Figures 5 and 6In some embodiments of the present invention, two grooving devices 1 are provided, one disposed between the loading station 71 and the grooving indexing station 72 and the other disposed between the grooving indexing station 72 and the unloading station 73. As the transfer platform 21 moves, the grooving devices 1 can perform grooving on the friction plate 8 on the transfer platform 21. By combining the two grooving devices 1 with the grooving indexing device 4, two grooving operations can be performed on the friction plate.

[0103] In the existing grooving equipment, the friction plate is mounted on the workpiece fixing plate by clipping. Such an installation is not suitable for the automated grooving processing of the friction plate. Therefore, in the first aspect of the present invention, a transfer platform that drives a magnetic attraction structure is provided, which is suitable for the automated grooving processing of the friction plate while stabilizing the friction plate. In some embodiments of the present invention, the transfer platform 21 includes a first transfer platform 211 and a second transfer platform 212, which are fixedly connected to each other; the first transfer platform 211 and the second transfer platform 212 are both provided with a first magnetic attraction component, and the first magnetic attraction component is used to magnetically attract the friction plate 8. The first magnetic attraction component is an electromagnetic coil wound around the two transfer platforms. By energizing, the electromagnetic coil generates an electromagnetic attraction force to adsorb and fix the friction plate. In this way, during the two grooving processes, since the friction plate is stably adsorbed on the transfer platform, two stable groovings of the friction plate can be achieved, thereby improving the grooving accuracy.

[0104] The distances between the first and second gripping and handling assemblies 31 and 41, the distance between the second and third gripping and handling assemblies 41 and 51, and the distance between the first and second transfer platforms 211 and 212 are all equal. This allows the transfer platforms to be precisely moved to the corresponding workstations for grooving the friction plate.

[0105] In some embodiments of the present invention, the first grabbing and handling assembly 31, the second grabbing and handling assembly 41, and the third grabbing and handling assembly 51 all feature a second magnetic assembly 6 for magnetically attracting the friction plate 8. During early development, existing gripping manipulators using negative pressure suction were designed. However, this approach struggled to achieve secure attachment and was prone to material dropout. This resulted in collisions between the friction plates, causing fragmentation and discs to fly, obliterating the mechanical workspace and potentially causing safety accidents. This is primarily due to the unique structure of the friction plates. The friction plates are composed of a steel plate and two paper sheets, positioned on either side of the steel. The paper sheets have a certain porosity, making negative pressure suction difficult to achieve stable attachment and prone to degassing, resulting in poor reliability. Therefore, the present invention, in its first aspect, designs a specialized gripping structure specifically for friction plate attachment. This structure utilizes magnetic attraction from the second magnetic assembly 6 to securely and securely hold the friction plate. Furthermore, by rationally designing key factors such as the matching of the magnetic attraction force with the friction plate's gravity and the matching of the spacing of the magnetic beads with the friction plate's dimensions, stable gripping of the friction plate is achieved.

[0106] In some preferred embodiments of the present invention, the first grabbing and transporting assembly 31, the second grabbing and transporting assembly 41, and the third grabbing and transporting assembly 51 are all provided with waist-shaped grooves, and each second magnetic attraction assembly 6 includes a connecting rod 61 and a magnetic column 62, one end of the connecting rod 61 is mounted on the waist-shaped groove, and the other end of each connecting rod 61 is fixedly connected to the magnetic column 62. Specifically, the multiple magnetic columns 62 on the first grabbing and transporting assembly 31 are all arranged on the same plane; the multiple magnetic columns 62 on the second grabbing and transporting assembly 41 are all arranged on the same plane; and the multiple magnetic columns 62 on the third grabbing and transporting assembly 51 are all arranged on the same plane. The connecting rod is fixedly mounted on the waist-shaped groove by bolts to achieve stable installation of the magnetic column 62, and due to the setting of the waist-shaped groove, the time spacing of the multiple magnetic columns 62 can be designed to match friction plates of different sizes.

[0107] See also Figures 2 to 4 In some embodiments of the present invention, the first grabbing and handling assembly 31 includes a first robotic arm assembly and a first linear drive assembly 313.

[0114] To achieve vibration reduction and improve stability for the notching device 1, the notching power assembly 17 of the spindle 15 and the mating surfaces of the column 11 are guaranteed to have a parallelism of less than 0.01, ensuring a fully fitted installation. High-precision angular contact bearings are selected for the support seat bearings at the front end of the spindle 15, and a preload is applied after installation to prevent axial movement. In the notching power assembly 17 of the spindle 15, the parallelism of the spindle rotation axis to the power base is 0.01. In the slide drive assembly 13 and slide assembly 12 of the column 11, the perpendicularity between the column 11 and the front of the slide is 0.015mm, and the perpendicularity between the column 11 and the side of the slide is 0.02. Furthermore, the worktable 7 also uses HT200, which has a vibration-absorbing effect. This improves the vibration reduction function and stability of the notching device 1.

The slide is slidably mounted on the column 11, with a sidewall of the slide secured to the nut, which is threadedly connected to a screw.

The slide drive assembly 13 includes a slide drive motor and a screw.

Start the conveying device 2, which conveys the first transfer platform 211 and the second transfer platform 212 to the groove indexing station 72 and the unloading station 73, respectively. At the same time, the groove engraving device 1 located on the side of the loading station 71 grooves the friction plate 8 on the first transfer platform;

[0125] The second grabbing and transporting assembly 41 is started. The second grabbing and transporting assembly 41 grabs the friction plate 8 on the first transfer platform 211 and rotates it to adjust the configuration angle of the friction plate 8 on the second transfer platform 212 .

[0126] S3, start the conveying device 2, and the conveying device 2 conveys the first transfer platform 211 and the second transfer platform 212 to the loading station 71 and the groove transfer station 72 respectively;

[0127] The first driving assembly 32 is started, and the first driving assembly 32 drives the first grabbing and transporting assembly 31 to move. The first grabbing and transporting assembly 31 grabs the friction plate 8 and transports it to the first transfer platform 211;

[0128] At the same time, the second grabbing and transporting assembly 41 is started, and the second grabbing and transporting assembly 41 places the friction plate 8 on the second transfer platform 212;

[0129] S4. Start the conveying device 2, which conveys the first transfer platform 211 and the second transfer platform 212 to the groove indexing station 72 and the unloading station 73, respectively. At the same time, the two groove carving devices 1 respectively groove the friction plates 8 on the first transfer platform 211 and the second transfer platform 212;

[0130] The second grabbing and transporting assembly 41 is started. The second grabbing and transporting assembly 41 grabs the friction plate 8 on the first transfer platform 211 and rotates it to adjust the configuration angle of the friction plate 8 on the second transfer platform 212 .

[0131] The third grabbing and transporting assembly 51 is started to grab the friction plate 8 on the second transfer platform 212, and the third driving assembly 52 is started to drive the third grabbing and transporting assembly 51 to move, so as to unload the friction plate 8.

[0132] S5. Repeat steps S3 to S4 to achieve automatic grooving of the friction plate 8.

[0133] Figure 11 The flow chart of the configuration of two transfer stations of the groove engraving method provided in the second aspect of the present invention. Wherein, transfer station ① represents the first transfer station; transfer station ② represents the second transfer station. Figure 11As shown in the figure, when the notching system is fully prepared, in the "original position", transfer table No. 1 is at the loading position, while transfer table No. 2 is at the rotating position, and there is no transfer table at the unloading position.

[0134] During the "first cycle loading": Transfer Table No. 1 is at the loading position, the loading position component starts to move, grabs the two friction plates on the storage tray at the same time and places them on Transfer Table No. 1, at this time there is no material on Transfer Table No. 2 at the rotation position, so the rotation position component does not move; when the material on Transfer Table No. 1 is finished, Transfer Tables No. 1 and 2 move to the right at the same time and are positioned directly below the first grooving spindle. At this time, the Y-axis grooving spindle completes the grooving operation of the product in the first direction on Transfer Table No. 1, such as: "first cycle rotation direction", at this time Transfer Table No. 1 moves to the rotation position, the grooving indexing component starts to move, grabs the products on the transfer table at the same time and rotates them 90°, then pauses and waits, at the same time Transfer Table No. 2 moves to the unloading position, because there is no material (no product) on the transfer table, the unloading position component does not move.

[0135] When the system determines that there is no material on transfer table No. ② at the unloading position and the rotation position has rotated the product 90° and is waiting in place, transfer tables No. 1 and No. ② move left at the same time and enter the "second cycle of rotating products and loading new products". At this time, transfer table No. ② with no material arrives at the rotation position, and the rotation position component moves to place the above-mentioned product rotated 90° on the empty transfer table No. ②. At the same time, transfer table No. 1 at the loading position performs loading operations.

[0136] When a new round of materials is completed on transfer table No. 1, transfer tables No. 1 and 2 move to the right at the same time again, that is, the new product on transfer table No. 1 is grooved in the first direction; the product on transfer table No. 2 after rotating 90° in the first cycle is grooved in the second direction, such as: "unloading is completed in the second cycle of rotation direction"; at this time, transfer table No. 1 moves to the rotation position, and the groove transfer assembly starts to move, sucking up the two new products on the transfer table and rotating them 90°, then pausing to wait. At the same time, the product on transfer table No. 2 that has completed the groove operation in the second direction moves to the unloading position, and the unloading position assembly starts to move, placing the products with grooves in both directions on the conveyor belt of the dust removal equipment.

[0137] When the system determines that there is no material on transfer table No. ② at the unloading position and the rotation position has rotated the product 90° and is waiting in place, transfer tables No. 1 and ② will move to the left at the same time again and enter the "third cycle of unloading and rotating products and loading new products". At this time, the material has been unloaded and it is empty; transfer table No. ② arrives at the rotation position, and the rotation position component moves to place the product that has been engraved in the first direction and rotated 90° and paused to wait in the second cycle on the empty transfer table No. ②. At the same time, transfer table No. 1, which has no material at the loading position, performs the third round of loading operation.

[0138] When the third round of new materials is completed on transfer table No. 1, transfer tables No. 1 and 2 move to the right at the same time again, that is, the third round of new products on transfer table No. 1 are grooved in the first direction, and the products on transfer table No. 2 are grooved in the second direction after rotating 90° in the second cycle, such as: "Unloading is completed in the third cycle of rotation direction". At this time, transfer table No. 1 moves to the rotation position, and the groove transfer assembly starts to move, sucking up the two new products on the third round on the transfer table at the same time and rotating them 90°, then pausing to wait. At the same time, the new products on transfer table No. 2 that have completed the second cycle and the second direction move to the unloading position, and the unloading position assembly starts to move, placing the products with grooves carved in both directions on the conveyor belt of the dust removal equipment again.

[0139] The above description is repeated in sequence to complete the automatic loading and unloading control of the friction groove.

[0140] The grooving system provided in the first aspect and the grooving method provided in the second aspect of the present invention overcome the frequent loading and unloading issues associated with traditional friction plate grooving, reducing worker labor intensity and nearly doubling loading and unloading efficiency and the grooving process's production capacity. Product consistency is significantly improved, with a grooving qualification rate exceeding 98%. This method significantly transforms the capabilities and capabilities of the friction plate straight groove processing and automotive parts processing industries, improving production efficiency and reducing costs. It is expected to save approximately 50% annually. Once successfully developed, this product can be promoted throughout the automotive parts processing industry, demonstrating significant market potential. Application on a single production line is expected to more than double production capacity, significantly enhance the consistency of mass production, and generate an estimated annual output value of over 500,000 yuan.

[0141] The productivity of the notching system of the first aspect and the notching method of the second aspect of the present invention is compared with that of the conventional notching equipment (prior art 2), as follows:

[0142] Taking the groove of a friction plate with an outer diameter of φ262 as an example, the production capacity of the traditional groove engraving equipment (prior art 2) and the groove engraving system provided by the first aspect of the present invention is compared.
