[0034] Reference Figures 2 to 6 An embodiment of the utility model provides a coating device, including: a gasket 10, an upper die head 12 and a lower die head 11, the gasket 10 is located between the extrusion gap formed by the upper die head 12 and the lower die head 11; scales 106A are set at both ends of the gasket 10, and the upper die head 12 and / or the lower die head 11 are provided with a main scale 106B matching the scale 106A.

[0035] In the above embodiment, a technical solution is adopted in which a scale 106A with the same scale is set at the same height position at both ends of the gasket 10, and a main scale 106B with the same scale is set at the same height position at both ends of the upper die head 12 and / or the lower die head 11. When the gasket 10 is installed with the die head, the gasket 10 can be installed on the scale line at the same height position at both ends of the upper die head 12 and / or the lower die head 11 according to the scale position of the main scale 106B at both ends of the upper die head 12 and / or the lower die head 11, so that when the gasket 10 is installed with the die head, it can be accurately The gasket 10 is positioned between the extrusion gap formed by the upper die head 12 and the lower die head 11, and since main scale 106B scale lines are provided at both ends of the upper die head 12 and / or the lower die head 11, when the gasket 10 is installed, the scale 106A at both ends of the gasket 10 cooperates with the main scale 106B at both ends of the upper die head 12 and / or the lower die head 11 respectively. The parallelism of the gasket 10 can be ensured by only keeping the main scale 106B installed at both ends of the gasket 10 on the upper die head 12 and / or the lower die head 11 consistent with the scale line values ​​of the scale 106A.

[0036] It is understandable that the scales 106A and the matching main scales 106B provided at both ends of the gasket 10 are engraved on the same side, which can achieve a matching effect. Figure 4 and Figure 5When the main scale 106B is engraved on the two ends of the surface of the upper die head 12 used to clamp the gasket 10 with the lower die head 11, the scale 106A on the gasket 10 and the main scale 106B on the upper die head 12 are located on the same side, which is convenient for the installation and positioning of the gasket 10 and the upper die head 12; similarly, when the main scale 106B is engraved on the two ends of the surface of the lower die head 11 used to clamp the gasket 10 with the upper die head 12, the installation of the gasket 10 is consistent with the above method. When the scale 106A scale is set on both sides of the two ends of the gasket 10, the main scale 106B scale is set at the place where the upper die head 12 and the lower die head 11 cooperate and contact with it. When installing the gasket 10, the gasket 10 can be installed in cooperation with the upper die head 12 or the lower die head 11, and there is no need to distinguish whether the scales of the scale 106A and the main scale 106B are on the same side, which is convenient for positioning the gasket 10 and the die head when installing.

[0037] Optional, see Figures 2 to 5 Adjustment parts 100 are provided at both ends of the gasket 10 , and micrometers 13 are provided at both ends of the top of the upper die head 12 . The micrometer 13 is connected with the adjustment part 100 to adjust the position and / or parallelism of the gasket 10 .

[0038] In the above embodiment, adjusting parts 100 are provided at both ends of the gasket 10, and micrometers 13 are provided at both ends of the top of the upper die head 12. Through the cooperation between the micrometer 13 and the adjusting part 100, the gasket 10 can be adjusted to move between the extrusion gap formed by the upper die head 12 and the lower die head 11, so as to adjust the relative position of the gasket 10 and the die head. In addition, adjusting parts 100 and micrometer 13 are provided at both ends of the gasket 10 and the micrometer 13, respectively. The purpose of adjusting the gasket 10 can be achieved by adjusting both ends at the same time or adjusting one end in place and then adjusting the other end.

[0039] It can be understood that in the above scheme, since the two ends of the gasket 10 are provided with a scale 106A, the matching upper die head 12 and / or lower die head 11 are provided with a main scale 106B, the main scale 106B and the scale 106A cooperate with each other and can be combined to form a vernier caliper or another one-thousandth scale set in the die head. By cooperating the adjustment part 100 of the gasket 10 with the micrometers 13 at both ends of the upper die head 12, the micrometer 13 can be connected with the combination of the main scale 106B and the scale 106A to correspond to each other, that is, the position of the scale 106A and the main scale 106B in the gasket 10 can be adjusted by adjusting the scale position of the external micrometer 13, and the specific position degree of the gasket 10 between the gap formed by the upper die head 12 and the lower die head 11 can be achieved by observing and recording the degree of the micrometer 13, and the parallelism data of the gasket 10 can be obtained by whether the values ​​of the readings of the micrometers 13 at both ends are consistent, so as to realize the positioning and adjustment of the position of the gasket 10 in the extrusion gap formed by the upper die head 12 and the lower die head 11.

[0040] Optional, such as Figure 4As shown, the gasket 10 is provided with a joint portion 101 along the width direction, the joint portion 101 is connected to the adjustment portions 100 at both ends, and the scale 106A is provided on the joint portion 101. The gasket 10 also includes baffles 102, which are connected to the joint portions 101 at both ends, and a coating opening is formed between the baffles 102.

[0041] In the above embodiment, the joint 101 is used to connect the adjustment part 100 and the baffle 102 respectively, an opening is formed between the joints 101, and the scale 106A is set on the joint 101. Since the joint 101 is set along the width direction of the gasket 10, it can be positioned and adjusted with the matching main scale 106B in the width direction of the gasket 10. The baffle 102 is used to block the paint on both sides, and a coating opening is formed between the baffles 102. The paint can be squeezed out from the coating opening for coating the electrode.

[0042] It should be noted that the scale 106A is set on the joint 101 to cooperate with the upper die 12 and / or the lower die 11, so that the installation position of the gasket 10 in the die can be clearly determined and the parallelism of the gasket 10 in the die can be confirmed through the readings at both ends. Specifically, when the gasket 10 is installed inside the die, the coating opening and the gasket body of the gasket 10 are respectively located at the front and rear ends of the die, and the joint 101 is arranged along the width direction of the gasket 10. After the scale 106A is set, it cooperates with the main scale 106B set by the upper die 12 and / or the lower die 11 to adjust the specific position of the gasket 10 before and after the die, and the parallelism of the gasket 10 installed in the die is judged by whether the values ​​of the main scale 106B at both ends are consistent with those of the scale 106A. It can be understood that when the main scale 106B at both ends are consistent with the reading values ​​of the scale 106A, it can be confirmed that the two ends of the gasket 10 are on the same horizontal line in the die, and when the main scale 106B at both ends are inconsistent with the reading values ​​of the scale 106A, it can be confirmed that the two ends of the gasket 10 are not on the same horizontal line in the die and are in an inclined state.

[0043] It can be understood that the adjustment part 100 is arranged at both ends of the gasket 10, which means that the adjustment part 100 is located at the tail of both ends of the gasket body in the length direction, the joint part 101 is connected to the adjustment part 100, the joint part 101 is located at both ends of the gasket 10 and is arranged along the width direction of the gasket 10, and an opening is formed between the joint parts 101, which means that since the joint parts 101 at both ends of the gasket 10 are not connected, the whole forms a structure with only one coating opening. When the gasket 10 is arranged between the gap formed by the upper die head 12 and the lower die head 11, the coating can only be squeezed out from the coating opening onto the foil. During coating, due to the pressure of the slurry in the die head, the slurry will undergo a certain advection and diffusion process after being squeezed onto the foil. Therefore, the front and rear position adjustment of the gasket 10 will directly affect the final coating width. Since the scale 106A is disposed on the joint 101, when the position of the scale 106A is adjusted, the gasket 10 can be moved backward or forward relative to the die head, that is, the position of the coating opening can be adjusted by adjusting the readings of the scale 106A and the main scale 106B, thereby adjusting the coating width.

[0044] Optional, such as Figure 4 , Figure 7 As shown, the adjusting portion 100 is provided with a protrusion 1000, and an adjusting rod 131 is provided at the bottom of the micrometer 13, and the adjusting rod 131 abuts against the protrusion 1000. The adjusting portion 100 is provided with an adjusting hole 1001 and / or an adjusting slot, and the adjusting rod 131 is provided at the bottom of the micrometer 13, and a clamping block 132 is provided at the bottom end of the adjusting rod 131, and the clamping block 132 is clamped with the adjusting hole 1001 and / or the adjusting slot.

[0045] In the above embodiment, the adjustment part 100 is the edge part at both ends of the gasket 10, and is provided with a protrusion 1000 perpendicular to the gasket 10. The protrusion 1000 can be abutted and cooperated with the adjustment rod 131 at the bottom of the micrometer 13. The micrometer 13 can be rotated to achieve the purpose of adjusting the gasket 10 to move downward. Furthermore, the adjustment part 100 is provided with an adjustment through hole and / or an adjustment groove, and a clamping block 132 is provided on the adjustment rod 131. The clamping block 132 is clamped with the adjustment hole 1001 and / or the adjustment groove. Rotating the micrometer 13 can not only make the gasket 10 move backward but also move it forward, thereby achieving the purpose of freely adjusting the position and parallelism of the gasket 10 in the adjustment direction.

[0046] Optional, such as Figures 3 to 5As shown, the gasket 10 also includes a gasket body, and a plurality of positioning sliding holes 103 are arranged side by side on the gasket body, so that the position of the gasket 10 can be slidably adjusted without opening the mold. The upper die head also includes a plurality of fastening holes 120 and a plurality of through holes 121, and the lower die head is provided with a plurality of threaded holes 110 that match the fastening holes 120 and the through holes 121; the upper die head 12 and the lower die head 11 are fixedly connected by bolts passing through the through holes 121 and the threaded holes 110, and the upper die head 12 and the lower die head 11 are also fastened by bolts passing through the fastening holes 120, the positioning sliding holes 103 and the threaded holes 110. The gasket body and the joint 101 are both provided with a plurality of avoidance holes 104, which are used to avoid the fastening bolts when the upper die head 12 and the lower die head 11 are fastened.

[0047] In the above embodiment, a plurality of positioning slide holes 103 are arranged side by side at the main body of the gasket 10. When the positioning slide holes 103 are fixed in the extrusion gap formed by the upper die head 12 and the lower die head 11, the gasket 10 is fixed and does not move due to the friction between the contact surfaces of the gasket 10 and the upper die head 12 and the lower die head 11. When the position or parallelism of the gasket 10 needs to be adjusted, it is only necessary to loosen the bolts fastening the upper die head 12 and the lower die head 11, so that the gasket 10, the upper die head 12 and the lower die head 11 are in contact and are not affected by the interaction force, and there is no need to loosen the upper die head 12 and the lower die head 11. 11 is completely disassembled, and at this time, by adjusting the value of the micrometer 13, the values ​​of the scale 106A and the main scale 106B can be adjusted, and then the position of the gasket 10 can be adjusted. The gasket 10 can slide within the length range of the positioning slide hole 103, so that the position of the gasket 10 can be adjusted while ensuring that the gasket 10 moves within a specified range. In addition, since the position of the gasket 10 can be adjusted by the micrometer 13 without opening the mold, the time spent on adjusting the gasket 10 can be effectively reduced, and at the same time, it is avoided that when the upper die head 12 and the lower die head 11 are completely disassembled in the prior art, part of the slurry will overflow, thereby causing the slurry to be scrapped.

[0048] It is understandable that when adjusting the gasket 10, the upper die head 12 and the lower die head 11 are not completely disassembled, but are only released from the fixed joint state under stress. At this time, there are bolts or other fasteners in the positioning slide hole 103, which can ensure that the gasket 10 does not fall and can slide within the length range of the positioning slide hole 103. The upper die head 12 is provided with a fastening hole 120 that matches the positioning slide hole 103, which is used to loosen the upper die head 12 and the lower die head 11 through fasteners, such as bolts, when adjusting the position of the gasket 10. After the adjustment is completed, the gasket 10 is fastened between the upper die head 12 and the lower die head 11 through the fasteners and the fastening holes 120.

[0049] Specifically, the upper die head 12 is provided with a plurality of through holes 121, and the lower die head 11 is provided with a plurality of threaded holes 110 matching with the through holes 121 for matching with the fastening bolts. When the upper die head 12 is fixedly connected with the lower die head 11, the bolt body passes through the through hole 121, and the bottom of the bolt is provided with an external thread matching with the threaded hole 110 to achieve the fastening of the upper die head 12 and the lower die head 11.

[0050] It is understandable that the gasket 10 and the joint 101 are both provided with a plurality of avoidance holes 104, the diameter of the avoidance holes 104 is larger than the diameter of the fastener body, and when the upper die head 12 and the lower die head 11 are loosened, the avoidance holes 104 and the bolt body are in a loose state, and the gasket 10 can move.

[0051] Optional, such as Figure 4 As shown, the baffle plate 102 is also provided with a plurality of through holes for the upper die head 12 and / or the lower die head 11 to cooperate with each other to form a flow channel.

[0052] It can be understood that the baffle 102 can be provided with a plurality of through holes according to actual conditions, wherein the shape of the through holes is determined by specific requirements, including regular rectangles, circles, triangles or any irregular shapes, which cooperate with the upper die head 12 and / or the lower die head 11 to form a delivery channel for conveying other coatings, and can fully utilize the gasket 10 material to form a multi-channel coating device 1.

[0053] Optional, such as Figure 2 , Figure 3 , Figure 5 As shown, the micrometer 13 is provided with a mounting frame 130, and the micrometer 13 is fixedly connected to the upper die head 12 or the lower die head 11 through the mounting frame 130. The micrometer 13 is provided with the mounting frame 130, which is convenient for disassembling or replacing the micrometer 13, and is convenient for spot inspection and maintenance of the coating device 1 before production.

[0054] It can be understood that when the micrometer 13 is installed on the upper die 12 through the mounting bracket 130, the direction of the protrusion 1000 or the adjustment groove set on the gasket 10 is consistent with that of the micrometer 13, that is, the protrusion 1000 or the adjustment groove is toward the side of the upper die 12, and when the micrometer 13 is installed on the lower die 11 through the mounting bracket 130, the protrusion 1000 or the adjustment groove is toward the side of the lower die 11, and they can cooperate with each other to ensure the adjustment effect of the gasket 10.

[0055] Optional, such as Figure 4 As shown, the gasket 10 is also provided with a plurality of positioning grooves 105, which are used to limit the placement of the gasket 10 when not in use. It can be understood that the gasket 10 is a consumable part in the coating device 1, and multiple gaskets need to be prepared for spare. When placed, the positioning grooves 105 cooperate with other components to overlap and place multiple gaskets 10 to prevent them from falling.

[0056] The actual operation process of the coating device is:

[0057] Install the gasket 10: first install the gasket 10 on the upper die head 12 or the lower die head 11, and read the scales 106A and the main scale 106B on both sides and confirm the parallelism. After confirming that the gasket 10 is in a parallel state on the upper die head 12 or the lower die head 11 and recording the readings of the scales 106A and the main scale 106B on both sides, fix the gasket 10 on the upper die head 12 or the lower die head 11 through the fixing hole 120, and finally close the lower die head 11 and the upper die head 12, and the bolts pass through the through holes 121 and cooperate with the nuts to lock the upper die head 12 and the lower die head, so as to install the gasket 10 in the die head.

[0058] Adjusting the gasket 10: In actual use, the coating width is affected by the position of the gasket 10 between the upper die 12 and the lower die 11. The position of the gasket 10 determines the actual coating area between the die and the substrate. If the position of the gasket 10 is improper, the coating area will be too wide or too narrow, thus affecting the coating width. Therefore, if it is necessary to adjust the front and rear position of the gasket 10 between the upper die 12 and the lower die 11, loosen the bolts in the fixing hole 120 and the through hole 121, and then adjust the front and rear position of the gasket 10 between the upper die 12 and the lower die 11 by screwing the micrometer 13 to complete the position adjustment of the gasket 10. Finally, tighten the fixing hole 120 and the through hole 121 in turn to fix the gasket 10, so as to achieve the purpose of adjusting the position of the gasket 10, and finally achieve the purpose of adjusting the coating width of the coating surface during coating. Furthermore, in the actual coating process, the coating surface density is also affected by the position and parallelism of the gasket 10 between the upper die 12 and the lower die 11. When the position or parallelism of the gasket 10 changes, the gap between the die and the substrate may become uneven, which will cause uneven distribution of the coating material on the substrate. Therefore, in order to ensure the stability and consistency of the coating surface density, when adjusting the position of the gasket 10, it is usually necessary to adjust the parallelism to ensure that the gap between the die and the substrate is uniform, so as to achieve uniform distribution of the coating material. When adjusting, first adjust the front and rear position of the gasket 10 between the upper die 12 and the lower die 11 by screwing the micrometer 13 to complete the position adjustment of the gasket 10, and then fine-tune until the values ​​of the micrometers 13 at both ends of the die are consistent, so as to ensure the parallelism of the gasket 10, and finally tighten the fixing holes 120 and the through holes 121 in sequence to achieve the fixation of the gasket 10, so as to achieve the purpose of adjusting the position and parallelism of the gasket 10.

[0059] In summary, the utility model provides a coating device, including a gasket 10, an upper die head 12 and a lower die head 11, the gasket 10 is located between the extrusion gap formed by the upper die head 12 and the lower die head 11; scales 106A are set at both ends of the gasket 10, and the upper die head 12 and / or the lower die head 11 are provided with a main scale 106B matching the scale 106A. The utility model sets rulers 106A at both ends of the gasket 10, and sets matching main rulers 106B at both ends of the upper die head 12 and / or the lower die head 11. When the die head and the gasket 10 are installed, the rulers 106A and the main rulers 106B at both ends cooperate with each other, so that the position of the gasket 10 can be accurately positioned between the extrusion gap formed by the upper die head 12 and the lower die head 11 during installation. In addition, since the main ruler 106B and the ruler 106A are set at both ends, the parallelism of the die head and the gasket 10 during installation can be guaranteed, and the cooperation between the ruler 106A and the main ruler 106B is conducive to adjusting the position and parallelism of the gasket 10. At the same time, micrometers 13 are provided at both ends of the die head. By linking the micrometer 13 with the gasket 10, the main scale 106B and the scale 106A of the gasket 10 can be reflected by the micrometer 13. In actual use, there is no need to completely disassemble the upper die head 12 and the lower die head 11, and the position of the gasket 10 can be adjusted by the micrometer 13, which can effectively reduce the time spent on adjusting the gasket 10 and avoid the situation in the prior art that when the upper die head 12 and the lower die head 11 are completely disassembled, part of the slurry overflows, thereby causing the slurry to be scrapped, and can effectively solve the technical problem in the prior art that the die head and the gasket 10 of the coating device 1 cannot be accurately positioned during installation.
