Description

Technical Field

[0001] The utility model relates to the technical field of coating machines and coating machine accessories, in particular to a coating die head. Background Art

[0002] The coating die is generally composed of an upper die, a lower die and a gasket. The gasket is clamped between the upper die and the lower die to form a slurry cavity and a coating lip connected to the slurry cavity. The slurry is extruded from the coating lip and coated on the foil to form a pole piece. After the coating is completed, the lip needs to be cleaned, and the coating die needs to be opened to clean the inside of the die. Kiss coating is a method of coating the slurry on the foil with the lip of the coating die facing up or down. During the coating process, the coating lip needs to be fitted to the foil or the distance between the coating lip and the foil needs to be controlled (the distance is controlled according to the coating requirements) for coating. During the kiss coating process, it is usually necessary to adjust the angle of the coating lip according to the actual situation so that coating can be performed at an appropriate angle.

[0003] The existing coating die usually includes a base, a die body rotatably mounted on the base, and a driving mechanism connected to the die body. The coating lip of the die body rotates to a desired angle because the driving mechanism drives the die body to rotate. However, it is difficult to accurately control the adjustment angle during the adjustment process, and the control accuracy is poor. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Example 1

[0039] See also Figures 1 to 8The present embodiment provides a coating die head, comprising: a support assembly, suitable for being fixedly arranged with an external device; a die body 1, rotatably arranged on the support assembly; a driving assembly, arranged on the support assembly; an output end of the driving assembly is drivingly connected to the die body 1, suitable for driving the die body 1 to rotate on the support assembly; an angle detection component 2, arranged on the support assembly and communicatively connected with the driving assembly, suitable for detecting the rotation angle of the die body 1.

[0040] It should be noted that the die body 1 has a coating lip 11 communicating with its inner cavity.

[0041] Communication connection refers to the communication between connected devices through signal transmission interaction, including wired connection (such as through wires, network cables, etc.) and wireless connection (such as WiFi, 4G connection, etc.).

[0042] In this embodiment, when it is necessary to adjust the angle of the die body 1 to change the spraying angle of its coating lip 11, the die body 1 can be driven to rotate on the support assembly through the output end of the driving assembly, thereby adjusting the angle of the die body 1, and the rotation angle of the die body 1 is detected by the angle detection component 2 during the rotation process to obtain the inclination angle of the die body 1. The angle threshold can be set by the program. When the angle detection component 2 detects that the rotation angle of the die body 1 reaches the angle threshold, it can be fed back to the driving assembly, and the die body 1 can be controlled to stop rotating through the driving assembly to achieve precise control of the inclination angle of the die body 1 and improve the adjustment accuracy.

[0043] Example 2

[0044] As a further improvement to Example 1, Figure 1 and Figure 2 As shown, the support assembly includes a first support seat 3 and a second support seat 4 arranged at intervals; one end of the die body 1 is rotatably connected to the first support seat 3 through a first rotating shaft 5, and the other end is rotatably connected to the second support seat 4 through a second rotating shaft 6; the output end of the drive assembly is drive-connected to the first rotating shaft 5.

[0045] It should be noted that the first rotating shaft 5 and the second rotating shaft 6 are coaxially arranged.

[0046] In this embodiment, a first rotating shaft 5 and a second rotating shaft 6 are respectively provided at both ends of the die body 1, and the first rotating shaft 5 and the second rotating shaft 6 are respectively rotatably cooperated with the first support seat 3 and the second support seat 4, so as to drive the die body 1 to rotate between the first support seat 3 and the second support seat 4, thereby improving the smoothness of the rotation.

[0047] Specifically, a first bearing is provided on the first support seat 3 corresponding to the first rotating shaft 5, and the end of the first rotating shaft 5 away from the die body 1 can be rotatably set in the first bearing. A second bearing is provided on the second support seat 4 corresponding to the second rotating shaft 6, and the end of the second rotating shaft 6 away from the die body 1 can be rotatably set in the second bearing. The support strength and the smoothness of the rotation of the die body 1 are improved by the first bearing and the second bearing.

[0048] Based on the above implementation, in a preferred implementation, Figure 1 and Figure 2 As shown, the angle detection component 2 is an encoder, which is communicatively connected with the driving assembly; the second rotating shaft 6 can rotate through the second supporting seat 4; the encoder is arranged on the side of the second supporting seat 4 away from the die body 1, and corresponds to the position of the second rotating shaft 6, and is suitable for detecting the rotation angle of the second rotating shaft 6.

[0049] It should be noted that one end of the second rotating shaft 6 away from the die body 1 passes through the second supporting seat 4 and extends into the encoder, so that the encoder can detect the rotation angle of the second rotating shaft 6 .

[0050] In this embodiment, an encoder is provided on the second support seat 4 to detect the rotation angle of the second rotating shaft 6, thereby obtaining the tilt angle of the die body 1, and cooperating with the driving component to improve the adjustment accuracy.

[0051] Specifically, the encoder is an angle encoder.

[0052] Based on the above implementation, in a preferred implementation, Figures 1 to 3 As shown, the coating die head also includes a locking assembly 7, which includes a first locking block 701 and a second locking block 702; one end of the first locking block 701 is hinged to one end of the second locking block 702, and the other end is connected to the other end of the second locking block 702 by a first screw; a clamping hole 703 is formed between the first locking block 701 and the second locking block 702, and the clamping hole 703 is suitable for clamping and locking the first rotating shaft 5 or the second rotating shaft 6; the second locking block 702 is fixedly arranged on the first support seat 3 or the second support seat 4.

[0053] It should be noted that the first locking block 701 and the second locking block 702 have a locking state for locking the first rotating shaft 5 or the second rotating shaft 6 , and a loosening state for loosening the first rotating shaft 5 or the second rotating shaft 6 .

[0054] In this embodiment, by setting a locking component 7, the locking component 7 can be set on the first support seat 3 to lock the first rotating shaft 5 or be set on the second support seat 4 to lock the second rotating shaft 6. When it is necessary to adjust the rotation of the die body 1, the first screw is adjusted to loosen, so that the clamping hole 703 between the first locking block 701 and the second locking block 702 is enlarged and then the first rotating shaft 5 or the second rotating shaft 6 is loosened, so that the first rotating shaft 5 or the second rotating shaft 6 can rotate in the clamping hole 703; after adjusting the inclination angle of the die body 1, the first screw is tightened to make the first locking block 701 close to the second locking block 702, so that the inner diameter of the clamping hole 703 is reduced and then the first rotating shaft 5 or the second rotating shaft 6 is locked, so as to avoid the displacement of the die body 1 and improve the stability.

[0055] Specifically, two groups of locking components 7 are provided, and the two groups of locking components 7 are respectively arranged on the first support seat 3 and the second support seat 4 to lock the first rotating shaft 5 and the second rotating shaft 6 to further improve stability.

[0056] Based on the above implementation, in a preferred implementation, Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the driving assembly includes a driving motor 8 and a reducer 9 connected in sequence; the reducer 9 is fixed on the supporting assembly; the output end of the driving motor 8 is connected to the input end of the reducer 9, and the output end of the reducer 9 is connected to the die body 1; the driving motor 8 is an encoder motor.

[0057] In this embodiment, the drive motor 8 uses an encoder motor to detect the rotation angle it adjusts, and then obtains the rotation angle of the die body 1, thereby achieving precise control of the rotation angle of the die body 1. The output torque is increased by the reducer 9, which facilitates the adjustment of the rotation angle of the die body 1 and improves stability.

[0058] Specifically, the encoder is communicatively connected with the drive motor 8 .

[0059] Specifically, the output end of the speed reducer 9 is drivingly connected to the first rotating shaft 5 .

[0060] Specifically, the output end of the reducer 9 is drivingly connected to the die body 1 through a coupling, which has a protective and buffering effect.

[0061] Based on the above implementation, in a preferred implementation, Figures 4 to 8As shown, the coating die also includes: a cleaning component 10, which is detachably connected to the die body 1; the cleaning end of the cleaning component 10 seals and covers the coating lip 11 of the die body 1; the die body 1 is provided with at least one switch valve 14 connected to its inner cavity, and the switch valve 14 is suitable for connecting to an external liquid supply device to provide a cleaning liquid.

[0062] It should be noted that the die body 1 has a feed port 13 communicating with its inner cavity.

[0063] In this embodiment, when the inner cavity of the die body 1 needs to be cleaned after coating is completed, a cleaning component 10 is set on the die body 1 to seal the coating lip 11 of the die body 1, and then the switch valve 14 is connected to the external liquid supply equipment through a pipeline. The cleaning liquid is provided by the external liquid supply equipment and then enters the inner cavity of the die body 1 through the switch valve 14. After the inner cavity of the die body 1 and the coating lip 11 are cleaned, the cleaning liquid is discharged through the feed port 13 to avoid the cleaning liquid from being discharged through the coating lip 11, thereby improving the cleaning effect; when coating is required, the cleaning component 10 can be disassembled.

[0064] Specifically, the die body 1 is provided with an emptying hole 12 communicating with the inner cavity thereof, and the switch valve 14 is arranged in the emptying hole 12 . The switch valve 14 is communicated with the inner cavity of the die body 1 through the emptying hole 12 .

[0065] Based on the above implementation, in a preferred implementation, Figures 4 to 8 As shown, the cleaning component 10 includes: a sealing cover 1001, having a cleaning chamber 1002 and an open end connected to the cleaning chamber 1002, and being detachably sealed and connected to the die body 1; the opening size of the open end is adapted to the size of the coating lip 11, and is suitable for covering the coating lip 11.

[0066] In this embodiment, when the inner cavity of the die body 1 needs to be cleaned, the coating lip 11 is covered by the open end of the sealing cover 1001 and the cleaning cavity 1002, and then the sealing cover 1001 is sealed and connected to the die body 1, and the cleaning liquid is introduced into the switch valve 14 for cleaning to improve the cleaning effect.

[0067] Based on the above implementation, in a preferred implementation, Figure 5 and Figure 8 As shown, a sealing strip 1003 for sealing the coating lip 11 is detachably connected in the cleaning chamber 1002 .

[0068] In this embodiment, a sealing strip 1003 is provided in the cleaning chamber 1002 to seal the coating lip 11, thereby improving the sealing effect and preventing the cleaning liquid after cleaning from entering the cleaning chamber 1002 through the coating lip 11, and preventing the cleaning liquid after cleaning from remaining in the cleaning chamber 1002, resulting in incomplete cleaning, thereby further improving the cleaning effect on the inner cavity of the die body 1 and the coating lip 11.

[0069] Specifically, the sealing strip 1003 is bonded to the inner wall of the cleaning chamber 1002 to facilitate installation and removal.

[0070] Specifically, the sealing strip 1003 is made of silicone or rubber to avoid damaging the coating lip 11 .

[0071] Based on the above implementation, in a preferred implementation, Figures 6 to 8 As shown, the two ends of the sealing cover 1001 are respectively provided with a liquid inlet 1004 and a liquid outlet 1005 connected to the cleaning chamber 1002, and the liquid inlet 1004 is suitable for connecting with an external liquid supply device; the liquid inlet 1004 and the liquid outlet 1005 are both detachably sealed with a blocking block 1006.

[0072] In this embodiment, a liquid inlet hole 1004 and a liquid outlet hole 1005 are respectively provided at both ends of the sealing cover 1001. When the inner cavity of the die body 1 is cleaned, the liquid inlet hole 1004 and the liquid outlet hole 1005 are sealed by a block 1006 to prevent the cleaning liquid from flowing out through the liquid inlet hole 1004 and the liquid outlet hole 1005 after passing through the coating lip 11, thereby affecting the cleaning effect of the inner cavity of the die body 1. When the cleaning of the inner cavity of the die body 1 is completed, the block 1006 can be removed, the liquid inlet hole 1004 can be connected to an external liquid supply device through a water inlet pipe, and the liquid outlet hole 1005 can be connected to an external recovery device through a sewage pipe. The cleaning liquid provided by the external liquid supply device enters the cleaning cavity 1002 of the sealing cover 1001 through the liquid inlet hole 1004 to clean the coating lip 11. At this time, the cleaning of the outer side of the coating lip 11 can be included, and then the cleaning liquid flows out from the liquid outlet hole 1005 to complete the cleaning of the coating lip 11.

[0073] Based on the above implementation, in a preferred implementation, Figure 8 As shown, a sealing ring 1007 is provided at the open end of the sealing cover 1001 .

[0074] It should be noted that the sealing ring 1007 is arranged around the opening of the open end.

[0075] In this embodiment, a sealing ring 1007 is provided between the open end of the sealing cover 1001 and the die body 1 to further improve the sealing effect and prevent leakage of the cleaning liquid during the cleaning process.

[0076] Specifically, a sealing groove for installing the sealing ring 1007 is provided at the open end of the sealing cover 1001 to facilitate the installation of the sealing ring 1007 .

[0077] Specifically, the sealing cover 1001 is connected to the die body 1 by a second screw, which is convenient for installation and disassembly.

[0078] The specific working principle of the coating die provided in this embodiment is as follows: when it is necessary to adjust the angle of the die body 1 to change the spraying angle of its coating lip 11, the first rotating shaft 5 can be driven to rotate by the driving motor 8 and the reducer 9, and then the die body 1 can be driven to rotate between the first support seat 3 and the second support seat 4, so as to adjust the angle of the die body 1, and during the rotation process, the rotation angle of the die body 1 is detected by the encoder and the encoder motor to improve the detection accuracy, so as to obtain the inclination angle of the die body 1, and the angle threshold can be set by the program. When the angle detection member 2 detects that the rotation angle of the die body 1 reaches the angle threshold, it can be fed back to the drive component, and the die body 1 is controlled to stop rotating by the drive component to achieve precise control of the inclination angle of the die body 1, thereby improving the adjustment accuracy, and at the same time, the first rotating shaft 5 or the second rotating shaft 6 is locked by the locking component 7 to avoid the deviation of the die body 1 and improve the stability; when the inner cavity of the die body 1 needs to be cleaned after the coating is completed, a sealing strip 1003 is set in the sealing cover 1001, and at the same time, a sealing strip 1003 is set in the sealing cover 1001, and at the same time, a sealing strip 1003 is set in the sealing cover 1001. The block 1006 seals the liquid inlet 1004 and the liquid outlet 1005, and seals the open end of the sealing cover 1001 to cover the coating lip 11, and fixes the sealing cover 1001 on the die body 1 by a second screw, and then the switch valve 14 is connected to the external liquid supply device through a pipeline, and the cleaning liquid is provided by the external liquid supply device and then enters the inner cavity of the die body 1 through the switch valve 14, and the inner cavity of the die body 1 and the coating lip 11 are cleaned and then discharged through the feed port 13, completing the cleaning of the inner cavity of the die body 1. After the inner cavity of the die body 1 is cleaned, the sealing strip 1003 and the blocking block 1006 are disassembled, and then the liquid inlet 1004 can be connected to the external liquid supply device through the water inlet pipe, and the liquid outlet 1005 can be connected to the external recovery device through the sewage pipe. The cleaning liquid provided by the external liquid supply device enters the cleaning cavity 1002 of the sealing cover 1001 through the liquid inlet 1004 to clean the coating lip 11. At this time, the cleaning of the outer side of the coating lip 11 can be included, and then the cleaning liquid flows out from the liquid outlet 1005 to complete the cleaning of the coating lip 11. The technical problem that it is difficult to accurately grasp the adjustment angle and the control accuracy of the existing coating die during the adjustment process is solved.

[0079] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
