An electric dispensing mechanism and electrode dispensing device

Abstract

This utility model discloses an electric dispensing mechanism and an electrode dispensing device. A drive motor drives a lead screw shaft, causing the lead screw nut to move up and down in the Z-direction, which in turn moves the dispensing valve up and down. A displacement detection component can detect the amount of displacement of the dispensing valve, further determining the distance of its movement. Furthermore, by sliding the dispensing valve along a guide component, its position in the X-direction can be adjusted, allowing the dispensing valve to coat ceramic slurry on substrates of different widths. This mechanism, through the coordinated arrangement of the drive motor and the lead screw shaft, precisely adjusts the height of the dispensing valve, accurately controlling the distance between the dispensing valve and the substrate, thereby precisely controlling the thickness of the ceramic coating.

Description

Technical Field

[0001] This utility model relates to the field of battery electrode production, specifically to an electric dispensing mechanism and electrode dispensing device. Background Technology

[0002] In energy storage devices such as lithium-ion batteries, the electrode is a core component. During battery operation, its edge areas may experience short circuits, corrosion, or performance degradation due to electrolyte penetration, ion migration, and mechanical stress. To overcome these drawbacks, ceramic coating processes for electrode edges have been gradually introduced. Current technologies mostly use dispensing valves to coat the electrode edges with ceramic, and control the distance between the dispensing valve and the substrate using a cylinder to control the ceramic coating thickness. However, cylinder control has low precision, requiring manual adjustment of a micro-motion platform. Manual adjustment introduces errors and hinders precise control of the dispensing valve position, resulting in an inability to accurately control the ceramic coating thickness. Utility Model Content

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0025] Please see Figure 1 This utility model provides a preferred embodiment of an electric dispensing mechanism, including a frame 1, a motor guide 2, a drive motor 3, a lead screw shaft 4, a lead screw nut 41, a displacement detection component 5, and a dispensing component 6. The Z direction is the vertical direction (height), the X direction is the horizontal direction (electrode width), and the Y direction is the horizontal direction (electrode conveying direction). The lead screw shaft 4 is arranged along the Z direction. The shaft of the drive motor 3 is connected to the lead screw shaft 4. Both the displacement detection component 5 and the dispensing component 6 are mounted on the lead screw nut 41. The displacement detection component 5 is used to detect the displacement of the dispensing component 6. The displacement of the dispensing assembly 6 is detected by the drive motor 3, which drives the lead screw shaft 4 to move the lead screw nut 41 up and down in the Z direction, thereby moving the dispensing assembly 6 up and down. The displacement detection component 5 can detect the displacement of the dispensing assembly 6 up and down and further determine the distance of the dispensing assembly 6 up and down. The motor guide 2 is mounted on the frame 1 in the Y direction. The drive motor 3 is slidably mounted on the motor guide 2 through the adapter plate 11. By sliding the adapter plate 11 along the motor guide 2, the position of the dispensing assembly 6 in the Y direction can be changed, which further facilitates the adjustment of the position of the dispensing assembly 6.

[0026] Specifically, the dispensing assembly 6 includes a dispensing guide 61 and a dispensing valve 62 arranged along the X direction. The dispensing guide 61 is fixedly mounted on the lead screw nut 41, and the dispensing valve 62 is slidably mounted on the dispensing guide 61. The height of the dispensing valve 62 can be adjusted by the cooperation of the drive motor 3 and the lead screw shaft 4 to precisely control the distance between the dispensing valve 62 and the substrate, thereby precisely controlling the thickness of the ceramic coating. Furthermore, the position of the dispensing valve 62 is adjustable in the X, Y, and Z directions, allowing for free spatial adjustment of the position of the dispensing valve 62 so that the dispensing valve 62 and the substrate are in a suitable relative position, which helps to ensure the accuracy of dispensing.

[0027] The displacement detection component 5 includes a displacement sensor 51 and a dial indicator 52. Both the displacement sensor 51 and the dial indicator 52 are mounted on the lead screw nut 41. The output end of the displacement sensor 51 is unidirectionally electrically connected to the input end of the drive motor 3. The displacement sensor 51 can convert the mechanical displacement of the dispensing valve 62 into an electrical signal and send the electrical signal to the drive motor 3 for feedback control. The operator can accurately understand the specific displacement value through the dial indicator 52, so as to facilitate the operator's judgment.

[0028] Please see Figure 4-5The dispensing assembly 6 also includes an adjusting member 63. The dispensing valve 62 is mounted on the adjusting member 63. The adjusting member 63 is slidably mounted on the dispensing guide member 61 in the X direction. The adjusting member 63 is used to adjust the position of the dispensing valve 62 in the X and Z directions. The distance that the dispensing valve 62 slides along the dispensing guide member 61 can be precisely controlled by the adjusting member 63. In addition, the adjusting member 63 can also help adjust the height of the dispensing valve 62, which further facilitates its use.

[0029] Please see Figure 5 In this embodiment, the dispensing guide 61 includes a first slide rail 611 and a first slider 612, with the first slider 612 slidably connected to the first slide rail 611; the adjusting member 63 includes a manual displacement stage 631, with the dispensing valve 62 installed at the moving end of the manual displacement stage 631, and the fixed end of the manual displacement stage 631 installed on the first slider 612 via a mounting plate 632. Real-time manual adjustment can be achieved by rotating the knob of the manual displacement stage 631 for rapid response, and during adjustment in the X direction, the mounting plate 632 drives the first slider 612 to slide along the first slide rail 611 to reduce friction during movement in the X direction.

[0030] To further ensure the accuracy of movement in the X direction, a first scale 633 is provided along the length of the first slide rail 611, and a first pointer 634 is provided on the mounting plate 632. The tip of the first pointer 634 faces the first scale 633. As the dispensing valve 62 moves along the X direction, the first pointer 634 moves along the first scale 633. By recording the first and last positions of the first pointer 634 on the first scale 633, the specific displacement value in the X direction can be calculated.

[0031] Please see Figure 2-3 In this embodiment, the motor guide 2 includes a second slide rail 21 and a second slider 22. The second slider 22 is slidably connected to the second slide rail 21, and the adapter plate 11 is fixedly installed on the second slider 22. The cooperation between the second slider 22 and the second slide rail 21 can reduce friction in the Y direction, making the drive motor 3 move more smoothly in the Y direction.

[0032] The frame 1 is provided with a slot 12 along the Y direction. The adapter plate 11 is provided with a limit bolt 111. The head of the limit bolt 111 is slidably disposed in the slot 12. During the movement of the adapter plate 11 along the Y direction, the limit bolt 111 moves along the length direction of the slot 12. The cooperation between the slot 12 and the limit bolt 111 can further limit the movement of the adapter plate 11 in the Y direction, reduce the sway or shaking of the adapter plate 11, and make the movement process more stable.

[0033] To further ensure the accuracy of movement in the Y direction, a second scale 13 with its length along the Y direction is provided on the frame 1, and a second pointer 14 is provided on the adapter plate 11 with the tip of the second pointer 14 pointing towards the second scale 13. As the adapter plate 11 moves along the Y direction, the second pointer 14 moves along the second scale 13. By recording the first and last positions of the second pointer 14 on the second scale 13, the specific displacement value in the Y direction can be calculated.

[0034] A preferred embodiment of this utility model also provides an electrode dispensing device, including a conveying mechanism and an electric dispensing mechanism as described in the above embodiment. The conveying mechanism is located below the dispensing valve 62 and is used to convey the substrate. By cooperating with the drive motor 3 and the lead screw 4, the height of the dispensing valve 62 can be precisely adjusted to precisely control the distance between the dispensing valve 62 and the substrate, thereby precisely controlling the thickness of the ceramic coating.

[0035] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
