Description

Technical Field

[0001] This invention relates to the field of graphite sheet feeding technology, and in particular to a graphite sheet feeding method and feeding device. Background Technology

[0002] like Figure 1 As shown, graphite sheet 80 is an important industrial material widely used in battery manufacturing, industrial furnace linings, chemicals, electronics, and other fields. The graphite sheet 80 has a first through hole 801 at its center. The first through hole 801 has the following functions: 1. It can serve as a heat dissipation channel to help dissipate the heat generated by the graphite sheet during operation; 2. Without affecting structural strength, the central opening can reduce material usage, thereby reducing the overall weight; 3. It is used to adapt to shafts or rods of specific equipment, facilitating the connection and fixation of the graphite sheet with other components.

[0003] Currently, there are two common methods for feeding graphite sheets:

[0004] I. Manual Loading: This method relies on workers to manually place graphite sheets into designated locations on processing equipment or production lines. However, manual loading has some significant drawbacks, especially in large-scale production and modern automated manufacturing environments: manual loading is slow, particularly when frequent changes or handling of large quantities of graphite sheets are required, making it incomparable to automated equipment; for heavy or large graphite sheets, manual handling and loading are very laborious, increasing the physical burden on workers; human factors can easily lead to inaccurate placement or omissions, especially after high-intensity or long-term work, where the error rate may increase.

[0005] Second, a vibrating feeder is used to uniformly transport graphite sheets to the designated position. However, when using a vibrating feeder to transport graphite sheets, excessive collisions and friction between the graphite sheets, as well as the tendency for overloading, can cause accumulation and pressure in the feeder, which can easily lead to the graphite sheets breaking.

[0006] Therefore, there is an urgent need to design a graphite sheet feeding device and method that is efficient, accurately positioned, and meets the requirements for automated feeding. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention discloses a graphite sheet feeding method and feeding device.

[0008] The technical solution adopted in this invention is as follows:

[0009] Firstly, a method for feeding graphite sheets is provided, including the following steps:

[0010] S1. Graphite sheets are loaded into separators, and the separators loaded with graphite sheets are stacked in a single first feeding unit of the feeding mechanism; if the current first feeding unit is full of separators loaded with graphite sheets, it is rotated to the next first feeding unit by a rotary mechanism, and the separators loaded with graphite sheets are stacked until each first feeding unit is full of separators loaded with graphite sheets; wherein, the feeding mechanism has a second feeding unit with an empty space;

[0011] S2. The first feeding unit, filled with a separator containing graphite sheets, rotates to the transfer mechanism; the transfer mechanism picks up the graphite sheets from the separator and transfers them to the storage mechanism;

[0012] Determine whether there is a graphite sheet inside the isolation sheet; if there is a graphite sheet, the transplanting mechanism continues to pick up the graphite sheet from the isolation sheet and transplant it to the designated location; if there is no graphite sheet, proceed to step S3;

[0013] S3. The second feeding unit rotates to the clamping mechanism, and the clamping mechanism clamps the separator sheet without graphite sheet to the second feeding unit until the second feeding unit is full of the separator sheet.

[0014] In one embodiment of the present invention, before the rotary mechanism rotates the feeding mechanism, the locking unit locks the first feeding unit and the second feeding unit.

[0015] In one embodiment of the present invention, in step S2, after the transplanting mechanism picks up the graphite sheet, it determines whether the thickness of the graphite sheet meets a preset value; if it does, the transplanting mechanism picks up the graphite sheet in the isolation sheet and transplants it to the storage mechanism; if it does not meet the preset value, the transplanting mechanism picks up the graphite sheet in the isolation sheet and transplants it to a designated location.

[0016] In one embodiment of the present invention, in step S3, for each graphite-free separator placed into the second feeding unit, the lifting mechanism lowers by the height of one separator until the second feeding unit is full of graphite-free separators.

[0017] Secondly, a graphite sheet feeding device is provided, comprising:

[0018] The feeding mechanism includes multiple first feeding units and one second feeding unit; the first feeding units are used to stack separators loaded with graphite sheets; the second feeding unit is used to stack separators without graphite sheets.

[0019] A rotary mechanism is used to rotate the feeding mechanism;

[0020] A transplanting mechanism is used to pick up the graphite sheets from the separator and transplant them to a storage mechanism;

[0022] In one embodiment of the present invention, both the first feeding unit and the second feeding unit include a base and a set of limiting posts disposed on the base; the position of the limiting posts on the base is adjustable.

[0023] In one embodiment of the present invention, the feeding mechanism further includes a plurality of locking units for locking the first feeding unit and the second feeding unit; the locking unit includes a support and a locking block slidably connected to the support; the locking block slides along its length direction.

[0024] In one embodiment of the present invention, the gripping mechanism includes a first linear motion unit, a lifting block connected to the movable part of the first linear motion unit, a gripping drive source disposed on the top of the first linear motion unit, and a gripper connected to the actuating part of the gripping drive source.

[0025] In one embodiment of the present invention, the transplanting mechanism includes a first linear module that moves along a first direction, a second linear module that moves along a second direction, a third linear module disposed on a movable portion of the first linear module and moving along a third direction, and a suction unit connected to the third linear module; the first linear module is disposed on the movable portion of the second linear module.

[0026] In one embodiment of the present invention, a lifting mechanism is further included; the lifting mechanism includes a second linear motion unit and a support block disposed on the working part of the second linear motion unit; the support block can enter the second feeding unit in a third direction.

[0027] In one embodiment of the present invention, a judging mechanism is further included for determining whether the thickness of the graphite sheet absorbed by the transplanting mechanism meets a preset value; the judging mechanism includes a base and a first sensing element and a second sensing element disposed on the same side of the base; the first sensing element is located above the second sensing element.

[0028] The technical solution of the present invention has the following advantages compared with the prior art:

[0057] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present invention. Furthermore, in all embodiments, the same reference numerals denote the same elements.

[0058] Example 1

[0059] Reference Figure 2 As shown, a method for feeding graphite sheets includes the following steps:

[0060] S1. Graphite sheets 80 are loaded into separators 90, and separators 90 loaded with graphite sheets 80 are stacked in a single first feeding unit of the feeding mechanism 10; if the current first feeding unit is full of separators 90 loaded with graphite sheets 80, it is rotated to the next first feeding unit by the rotary mechanism 20, and the separators 90 loaded with graphite sheets 80 are stacked until each first feeding unit is full of separators 90 loaded with graphite sheets 80; wherein, the feeding mechanism 10 has a second feeding unit with an empty space;

[0061] S2. The first feeding unit, which is filled with the separator 90 containing graphite sheets 80, rotates to the transfer mechanism 50; the transfer mechanism 50 picks up the graphite sheets 80 from the separator 90 and transfers them to the storage mechanism 70.

[0062] Determine whether there is a graphite sheet 80 inside the isolation plate 90; if there is a graphite sheet 80, the transplanting mechanism 50 continues to pick up the graphite sheet 80 inside the isolation plate 90 and transplant it to the designated location; if there is no graphite sheet 80, proceed to step S3;

[0063] S3. The second feeding unit rotates to the clamping mechanism 30. The clamping mechanism 30 clamps the isolation sheet 90 without graphite sheet 80 to the second feeding unit until the second feeding unit is full of isolation sheet 90.

[0064] This embodiment provides a graphite sheet feeding method that allows for continuous feeding, significantly improving production efficiency and reducing downtime; it also enables the placement of graphite sheets with higher precision and consistency, reducing human error.

[0065] In this embodiment, before the rotary mechanism 20 rotates the feeding mechanism 10, the locking unit 13 locks the first feeding unit and the second feeding unit.

[0066] In this embodiment, in step S2, after the transplanting mechanism 50 picks up the graphite sheet 80, it determines whether the thickness of the graphite sheet 80 meets the preset value; if it does, the transplanting mechanism 50 picks up the graphite sheet 80 in the isolation sheet 90 and transplants it to the storage mechanism 70; if it does not meet the preset value, the transplanting mechanism 50 picks up the graphite sheet 80 in the isolation sheet 90 and transplants it to the designated location.

[0067] In this embodiment, in step S3, for each graphite-free separator 90 placed into the second feeding unit, the lifting mechanism 40 lowers by the height of one separator 90 until the second feeding unit is filled with graphite-free separators 90.

[0068] Example 2

[0069] Combination Figure 3 and Figure 4 A graphite sheet feeding device includes a feeding mechanism 10, a rotary mechanism 20, a transfer mechanism 50, and a clamping mechanism 30.

[0070] The feeding mechanism 10 includes multiple first feeding units and one second feeding unit. The first feeding units are used to stack separator sheets 90 loaded with graphite sheets 80. The second feeding unit is used to stack separator sheets 90 without graphite sheets 80.

[0071] The rotary mechanism 20 is used to rotate the feeding mechanism 10.

[0072] The transplanting mechanism 50 is used to pick up the graphite sheet 80 inside the isolation sheet 90 and transplant it to the storage mechanism 70.

[0073] The clamping mechanism 30 is used to clamp the separator 90 without graphite sheet 80 to the second feeding unit.

[0074] This embodiment provides a graphite sheet feeding device that can adapt to graphite sheets of different sizes, is easy to integrate with existing production lines, and realizes automation of the entire production process.

[0075] In this embodiment, as Figure 3 As shown, the feeding mechanism 10 includes seven first feeding units and one second feeding unit, which means that the feeding mechanism 10 has eight stations.

[0076] In this embodiment, combined with Figure 6 and Figure 7 The separator 90 includes a circular substrate 901, with a second through hole 902 at the center of the substrate 901 and a third notch 903 at the edge of the substrate 901. The diameter of the first through hole 801 of the graphite sheet 80 is smaller than the diameter of the second through hole 902.

[0077] In this embodiment, as Figure 8 As shown, both the first and second feeding units include a base 12 and a set of limiting posts 11 disposed on the base 12. The position of the limiting posts 11 on the base 12 is adjustable. Specifically, the base 12 is a circular component, and a first notch 122 is formed on the edge of the base 12. The first notch 122 is used to cooperate with a third notch 903 to indicate the correct installation of the isolation piece 90 and to subsequently avoid the support block 42 of the lifting mechanism 40 from entering the second feeding unit. At least one set of adjusting holes 121 are symmetrically formed on the base 12 about the first notch 122. The opening direction of the adjusting holes 121 is along the radial direction of the base 12. Generally, the adjusting holes 121 are oblong grooves.

[0078] According to the diameter of the graphite sheet 80, the position of the limiting post 11 on the base 12 is adjusted, and the limiting post 11 is fixed by passing a screw or bolt through the adjustment hole 121, so as to accommodate graphite sheets 80 of different sizes.

[0079] In this embodiment, the feeding mechanism 10 further includes eight locking units 13 for locking the first feeding unit or the second feeding unit. Each locking unit 13 includes a support 131 fixed to the rotary plate 21 and a locking block 133 slidably connected to the support 131. The locking block 133 slides along its length. Specifically, the locking unit 13 also includes a guide rod 132, a slider 135, and a guide rail 136. One end of the guide rod 132 is fixed to the support 131. The guide rod 132 passes axially through the locking block 133 and is slidably connected to it. The guide rail 136 is fixed to the rotary plate 21, and the slider 135 slides along the direction of the guide rail 136. The slider 135 is fixed to the bottom of the locking block 133.

[0080] Furthermore, such as Figure 9 As shown, to further fix the first or second feeding unit onto the rotary plate 21, the locking unit 13 also includes a pull member 134 disposed on the locking block 133. The pull member 134 can be a knob, which allows the operator to push the locking block 133 to lock the first or second feeding unit, preventing the first or second feeding unit from moving or rotating during the rotation of the rotary plate 21, and protecting the feeding mechanism 10, the isolation plate 90, and the graphite sheet 80.

[0081] Furthermore, an identification hole 137 is provided on the locking block 133 near the base 12. The identification hole 137 is used to determine whether the locking unit 13 locks the first feeding unit or the second feeding unit. Specifically, a first photoelectric sensor (not shown in the figure) is pre-installed below the rotary plate 21, and the rotary plate 21 has a channel for the light beam of the first photoelectric sensor to pass through. The first photoelectric sensor is used to determine whether the locking unit 13 locks the first feeding unit or the second feeding unit. When the locking block 133 locks the first feeding unit or the second feeding unit, the light beam emitted by the first photoelectric sensor is interrupted by the locking block 133, thereby detecting that the locking unit 13 has locked the first feeding unit or the second feeding unit; when the locking block 133 does not lock the first feeding unit or the second feeding unit, the light beam emitted by the first photoelectric sensor passes through the channel and the identification hole 137, thereby detecting that the locking unit 13 has not locked the first feeding unit or the second feeding unit.

[0082] In this embodiment, as Figure 10As shown, the rotary mechanism 20 includes a rotary drive source 22 and a rotary plate 21 connected to the working part of the rotary drive source 22. The rotary plate 21 is used to install eight stations of the feeding mechanism 10. Furthermore, the rotary plate 21 has eight second notches 211 on its edge. The second notches 211 are used to cooperate with the first notches 122 to indicate the correct installation of the first and second feeding units and to subsequently avoid the support block 42 of the lifting mechanism 40 entering the second feeding unit. The rotary drive source 22 can employ a cam divider to convert continuous rotational motion into intermittent, evenly distributed stepping motion, facilitating the stacking of the isolation sheet 90 loaded with graphite sheets 80 by the operator. The rotary plate 21 is then connected to the output shaft of the rotary drive source 22.

[0083] Furthermore, the input shaft of the rotary drive source 22 is equipped with a cam 23, and a second photoelectric sensor 24 is mounted on the rotary drive source 22. Each time the rotary drive source 22 rotates, the cam 23 blocks the light from the second photoelectric sensor 24, generating a pulse signal. The number of rotations can be determined by counting these pulses.

[0084] In this embodiment, as Figure 11 As shown, the gripping mechanism 30 includes a first linear motion unit 33, a lifting block 35 connected to the movable part of the first linear motion unit 33, a gripping drive source 31 disposed on the top of the first linear motion unit 33, and a gripper 32 connected to the actuating part of the gripping drive source 31. The first linear motion unit 33 can be a commercially available linear module. The gripping drive source 31 can be a gripper cylinder. The movable part of the first linear motion unit 33 is connected to a connecting seat 34, and the lifting block 35 is fixed to the connecting seat 34. The gripper 32 is detachably connected to the gripping drive source 31, thereby adapting to graphite sheets 80 of different diameters.

[0085] It should be noted that "detachable connection" means that the gripper 32 and the action part of the gripping drive source 31 can be fixedly connected by fastening elements such as bolts. When it is necessary to disassemble or separate the gripper 32 and the action part of the gripping drive source 31, the fastening elements can be loosened, the gripper 32 can be removed from the action part of the gripping drive source 31, and a gripper 32 of other sizes can be replaced.

[0086] In this embodiment, as Figure 13 As shown, the transplanting mechanism 50 includes a first linear module 51 that moves in a first direction, a second linear module 52 that moves in a second direction, a third linear module 53 that is located on the movable part of the first linear module 51 and moves in a third direction, and a suction unit 54 connected to the third linear module 53. The first linear module 51 is located on the movable part of the second linear module 52. Wherein, as... Figure 3As shown, a local coordinate system is established, with the first direction of motion being the X-axis, the second direction being the Y-axis, and the third direction being the Z-axis. The suction unit 54 can be a vacuum suction head.

[0087] In this embodiment, a third photoelectric sensor (not shown in the figure) can be installed above the first feeding unit near the transplanting mechanism 50. The third photoelectric sensor is used to determine whether there is a graphite sheet 80 inside the isolation plate 90. Specifically, when there is no graphite sheet 80 inside the isolation plate 90, the light beam emitted by the third photoelectric sensor can pass through the second through hole 902, thereby detecting that there is no graphite sheet 80 inside the isolation plate 90; when there is a graphite sheet 80 inside the isolation plate 90, the light beam emitted by the third photoelectric sensor is interrupted by the graphite sheet 80, thereby detecting that there is a graphite sheet 80 inside the isolation plate 90. Obviously, the installation position of the third photoelectric sensor is designed according to the diameter of the second through hole 902 of the isolation plate 90.

[0088] In this embodiment, as Figure 12 As shown, the graphite sheet feeding device also includes a lifting mechanism 40. The lifting mechanism 40 includes a second linear motion unit 41 and a support block 42 disposed on the working part of the second linear motion unit 41. The support block 42 can enter the second feeding unit in a third direction. The second linear motion unit 41 can be a commercially available electric cylinder. In the initial state, the working part of the second linear motion unit 41, together with the support block 42, enters the second feeding unit. Each time a separator 90 without graphite sheet 80 is placed in the second feeding unit, the second linear motion unit 41 drives the support block 42 to descend by the height of one separator 90, so that the second feeding unit can hold the next separator 90 without graphite sheet 80.

[0089] In this embodiment, as Figure 14 As shown, the graphite sheet feeding device also includes a judgment mechanism 60 for determining whether the thickness of the graphite sheet 80 picked up by the transfer mechanism 50 meets a preset value. The judgment mechanism 60 includes a base 61 and a first sensing element 62 and a second sensing element 63 disposed on the same side of the base 61. The first sensing element 62 is located above the second sensing element 63. Specifically, the first sensing element 62 and the second sensing element 63 can be selected from sensors suitable for measuring thickness, such as ultrasonic sensors, laser sensors, capacitive sensors, or inductive sensors. The first sensing element 62 and the second sensing element 63 are precisely mounted on the upper and lower sides of the graphite sheet 80, and the measuring surfaces of the first sensing element 62 and the second sensing element 63 are parallel to the surface of the graphite sheet 80. The thickness can be indirectly calculated by measuring the influence of the graphite sheet 80 on the signals of the first sensing element 62 and the second sensing element 63. For example, for an ultrasonic sensor, the thickness h can be calculated using the sound velocity v and the signal propagation time t (assuming the sound wave propagates round trip in the graphite sheet 80):

[0090]

[0091] The graphite sheet feeding method in this embodiment is the same as the graphite sheet feeding method provided in Embodiment 1, and will not be described again here.

[0092] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0093] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
