Description

Technical Field

[0001] This invention relates to the field of coating apparatus technology, and more particularly to a flow regulating mechanism, a coating die head, and a coating apparatus. Background Technology

[0002] Slot coating, a precision wet coating technology, works by extruding slurry under pressure and flow rate through the slots of a coating die and transferring it onto the substrate. Compared to other coating methods, it offers many advantages, such as high coating speed, high precision, and uniform wet thickness.

[0003] Existing coating dies consist of an upper die, a lower die, and a spacer sandwiched between them. The slurry is extruded from a coating slit and applied to the substrate. Due to factors such as slurry temperature or viscosity, the coating thickness is uneven, requiring adjustment. Therefore, a flow regulation mechanism is typically installed in the upper die to change the flow rate at the coating slit. This flow regulation mechanism comprises multiple regulating blocks and a micro-head or actuator. When flow regulation is not required, the regulating blocks are retracted into the receiving groove of the upper die. During flow regulation, the micro-head is rotated to lower the regulating blocks from the receiving groove to the coating slit.

[0004] However, the flow regulation mechanism is fixed on the upper mold head, which occupies a large vertical space. For the overall equipment assembled with this flow regulation mechanism, a large packaging box is required during transportation, and the protruding regulation device is easily damaged by collisions, which may affect the sensitivity of the regulation or even cause the regulation device to be scrapped.

[0068] This invention proposes a flow regulating mechanism applicable to coating devices, particularly slit extrusion coating devices, but not limited thereto.

[0069] Reference Figure 1 In one embodiment of the present invention, the flow regulation mechanism includes a drive component 10, a reversing component 20, and an execution component 30; the drive component 10 is adapted to be mounted on the coating die head; the input end of the reversing component 20 is drivenly connected to the output end of the drive component 10 to reverse the driving direction of the drive component 10; the execution component 30 is adapted to extend into the coating slit of the coating die head, and the input end of the execution component 30 is connected to the output end of the reversing component 20; the drive component 10 is used to drive the reversing component 20 to move and drive the execution component 30 to adjust the output amount of the coating slit.

[0070] In this embodiment, the drive component 10 may use the motor 12 as the power output component, which is not limited here.

[0071] The reversing assembly 20 can be a cam mechanism or a wedge block mechanism, etc., whichever is more specific.

[0072] The actuator 30 may be a T-block 310, or it may include an adjusting rod and an adjusting bar connected to the adjusting rod; no specific limitation is made here.

[0073] Main Reference Figure 2 When the execution component 30 is a T-shaped block 310, the T-shaped block 310 may include a rod 311 and a flow-stopping block 312 connected to one end of the rod 311, and the other end of the rod 311 is connected to the reversing component 20.

[0074] In the technical solution of this invention, the flow regulation mechanism includes a drive component 10, a reversing component 20, and an execution component 30. The drive component 10 is adapted to be mounted on the coating die head. The input end of the reversing component 20 is drivenly connected to the output end of the drive component 10 to reverse the driving direction of the drive component 10. The execution component 30 is adapted to extend into the coating slit of the coating die head, and the input end of the execution component 30 is connected to the output end of the reversing component 20. The drive component 10 is used to drive the reversing component 20 to move and drive the execution component 30 to adjust the output of the coating slit. It can be understood that by setting the drive component 10 to drive the reversing component 20 to move and drive the execution component 30 to adjust the output of the coating slit, the flow regulation function is realized. At the same time, since the reversing component 20 reverses the driving direction of the drive component 10, the entire flow regulation mechanism can be set along the length direction of the coating die head, reducing the space occupied by the flow regulation mechanism in the height direction of the whole machine, facilitating packaging and transportation, and avoiding damage caused by collision.

[0075] refer to Figure 1 and Figure 2 In one embodiment, the drive assembly 10 includes a drive board 11 and a motor 12 electrically connected to the drive board 11.

[0076] In this embodiment, the drive board 11 controls the motor 12, and the output shaft 121 of the motor 12 is connected to the input end of the commutation assembly 20.

[0077] The drive assembly 10 may also include a fixed base, on which the motor 12 and the drive plate 11 are mounted, and the fixed base is fixed to the coating die head.

[0078] refer to Figure 2 and Figure 3 In one embodiment, the reversing component 20 may be a cam component 210, which includes a cam seat 211, a slider 212, and a cam 213. The slider 212 is slidably disposed on the cam seat 211 and is connected to the actuation component 30. Furthermore, the sliding direction of the slider 212 is perpendicular to the extension direction of the output shaft 121 of the motor 12. The cam 213 is rotatably embedded in the slider 212 and fixed on the output shaft 121 of the motor 12.

[0079] It is understandable that the rotation of motor 12 can drive cam 213 to rotate, and the rotation of cam 213 can drive slider 212 to reciprocate within cam seat 211. Slider 212 can then drive actuator 30 to move along the height direction of coating die head to adjust coating surface density.

[0080] In one embodiment, the cam seat 211 may have a groove, through which the slider 212 is slidably connected to the cam seat 211. This allows the slider 212 to reciprocate on the cam seat 211, improving the smoothness of the movement of the actuator 30 and enhancing the uniformity of the coating.

[0081] Of course, for reference Figure 2 and Figure 3 In some other embodiments, the cam seat 211 may be provided with a cross roller guide 214, and the slider 212 is slidably connected to the cam seat 211 through the cross roller guide 214, so as to greatly improve the smoothness of the slider 212 and thus improve the accuracy of flow control.

[0082] refer to Figure 2 In one embodiment, the commutation assembly 20 may further include a bearing 215, through which the output shaft 121 of the motor 12 passes and is connected to the cam 213.

[0083] In this embodiment, by adding a bearing 215, the eccentric rotation of the far end of the output shaft 121 of the motor 12 can be limited, thereby improving the motion stability of the actuator 30, enhancing the accuracy of flow control, and improving the uniformity of coating.

[0084] To further improve the accuracy of the flow regulation mechanism in regulating the flow rate, thereby improving the coating quality, refer to Figure 2In one embodiment, the reversing assembly 20 may further include a displacement measuring element disposed on the cam seat 211 for detecting the amount of displacement of the slider 212 relative to the cam seat 211.

[0085] refer to Figure 2 In one embodiment, the displacement measuring element may be a grating ruler assembly, which includes a grating ruler 216 and a grating ruler reading head 217. The grating ruler 216 is disposed between the sliding member 212 and the cam seat 211, and the grating ruler reading head 217 is disposed on the grating ruler 216 and is signal-connected to the drive board 11.

[0086] refer to Figure 2 In another embodiment, the displacement measuring element may also be an LVDT displacement sensor 218, which is disposed on the cam seat 211 and connected to the drive board 11 via signal.

[0087] Of course, in some other embodiments, reference Figure 2 Alternatively, a combination of a grating ruler assembly and an LVDT displacement sensor 218 can be used, or other displacement sensors can be used to detect the displacement of the slider 212 relative to the cam seat 211. No limitation is made here.

[0088] In one embodiment, the motor 12 is a linear motor 12; the commutation component 20 is a first wedge follower component, which may include a wedge block, a follower wheel, and a self-restoring elastic shaft; one end of the wedge block is connected to the output shaft 121 of the linear motor 12; the follower wheel abuts against the inclined surface of the wedge block; the first end of the self-restoring elastic shaft is fixedly connected to the follower wheel, and the second end of the self-restoring elastic shaft is connected to the actuation component 30.

[0089] In this embodiment, the output shaft 121 of the linear motor 12 drives the wedge block to extend forward, the follower wheel drives the self-restoring elastic shaft to press down, and then drives the actuator 30 to press down, thereby realizing flow regulation. Similarly, the output shaft 121 of the linear motor 12 drives the wedge block back to the initial position, the follower wheel rebounds under the action of the self-restoring elastic shaft, and drives the actuator 30 to rebound to the initial position.

[0090] refer to Figures 4 to 6In one embodiment, the reversing component 20 may be a second wedge-shaped follower component 230, which includes a lead screw 231, a nut seat 232, a first wedge block 233, a second wedge block 234, an elastic element 235, and two slide rails 236. The lead screw 231 is connected to the output shaft 121 of the motor 12. The nut seat 232 is disposed on the lead screw 231. The first wedge block 233 is fixed on the nut seat 232. The second wedge block 234 is adapted to the first wedge block 233 and is connected to the actuation component 30. The elastic element 235 pulls the first wedge block 233 and the second wedge block 234 together. The nut seat 232 is disposed on one of its slide rails 236 so that the nut seat 232 moves in a first direction. The second wedge block 234 is disposed on the other slide rail 236 so that the second wedge block 234 moves in a second direction.

[0091] Among them, the elastic element 235 can preferably be a tension spring, but is not limited here.

[0092] In this embodiment, the first direction can be the horizontal direction, that is, the length direction of the coating die head; the second direction can be the height direction of the coating die head.

[0093] In this embodiment, the lead screw 231 reverses the driving direction of the motor 12. Driven by the motor 12, the lead screw 231 moves the first wedge block 233, and through the second wedge block 234, it drives the actuator 30 to move in the second direction. The elastic element 235 can tighten the first wedge block 233 and the second wedge block 234 to ensure that both wedge blocks can return to their initial positions.

[0094] In addition, in this embodiment, a displacement measuring device can also be used to detect the displacement of the second wedge block 234 relative to the first wedge block 233 to improve control accuracy. The displacement measuring device can also be a grating ruler assembly or an LVDT displacement sensor 218, etc., and is not limited here.

[0095] refer to Figure 4 and Figure 5 In order to protect the cam assembly 210 or the wedge follower assembly and improve the service life of the commutation assembly 20, in one embodiment, the commutation assembly 20 further includes a commutation housing 240, which covers the cam assembly 210 / first wedge follower assembly / second wedge follower assembly 230.

[0096] The present invention also proposes a coating die head, which includes a flow regulating mechanism. The specific structure of the flow regulating mechanism is as described in the above embodiments. Since the coating die head proposed in the present invention includes all the solutions of all embodiments of the above flow regulating mechanism, it has at least the same technical effects as the flow regulating mechanism, which will not be described in detail here.

[0097] In one embodiment of the present invention, the coating die head includes a first die head, a second die head, and at least one flow regulating mechanism; the first die head is provided with at least one slot; the second die head is connected and fixed to the first die head and forms a coating slit communicating with the slot; the number of flow regulating mechanisms is the same as the number of slots, and the flow regulating mechanism is installed on the first die head and extends into the coating slit through the slot.

[0098] In this embodiment, the first mold head has a receiving groove, and at least one flow regulating mechanism is fixed in the receiving groove.

[0099] In other words, the flow regulating mechanism of the present invention can be fixed to the first die head without changing the size of the existing coating die head. Only a fixing hole needs to be opened on the die head to fix the flow regulating mechanism. This results in a small change in the volume of the coating die head and eliminates the need for extensive cutting of the die head. Alternatively, the flow regulating mechanism can be housed in a receiving groove. In this way, the overall volume of the coating die head can be reduced without increasing the space occupied, greatly saving space, facilitating packaging and transportation, and preventing damage from collisions.

[0100] To further protect the flow regulating mechanism, in one embodiment, a protective cover is provided on the receiving groove.

[0101] In one embodiment, a protruding beam is provided on the first mold head along its length direction, the drive assembly 10 of the flow regulating mechanism is fixed on the protruding beam, and the protruding beam is provided with a through hole for the output end of the drive assembly 10 to pass through. In this way, the drive assembly 10 of the flow regulating mechanism can be installed conveniently, improving the ease of assembly.

[0102] The present invention also proposes a coating apparatus, which includes a coating die head. The specific structure of the coating die head is as described in the above embodiments. Since the coating apparatus proposed in this invention includes all schemes of all embodiments of the above-described coating die head, it has at least the same technical effects as the coating die head, which will not be described in detail here.

[0103] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
