Description

Technical Field

[0001] The present application relates to the technical field of coating die heads, and in particular to a quantitative adjustment device for coating die head gaskets. Background Art

[0002] The coating die head consists of an upper die head, a lower die head and a gasket sandwiched therebetween. A cavity is opened on the lower die head, and the slurry enters the cavity from the feed port. A notch is set at the front end of the gasket for the slurry to flow out. The upper die head, the lower die head and the gasket are surrounded to form a coating slit. The slurry passes through the coating slit and is squeezed from the coating lip to the substrate on the coating roller, forming a functional layer on the substrate.

[0003] However, during the installation of the gasket, a millimeter-level error will have a great impact on the coating effect. Especially when the coating die head is used for a long time, the coating die head lip is worn and needs to be disassembled and ground. The grinding of the coating die head lip causes the shrinkage between the gasket and the coating die head lip to change.

[0004] The installation method of the die head gasket is still to rely on the cooperation of multiple people to determine whether the gasket is installed in place based on naked eye observation and touch, which has a large error. The coating die head with insufficient gasket installation accuracy will cause the coating size and surface density to fail to meet the process requirements during the production process, so the gasket needs to be reinstalled, which will lead to waste of materials such as slurry and current collector, affecting material utilization. Summary of the invention

[0005] The embodiment of the present application provides a quantitative adjustment device for a coating die head gasket to solve the problem in the related art that the die head gasket has a large installation error, resulting in the coating size and surface density not meeting the process requirements.

[0006] The embodiment of the present application provides a quantitative adjustment device for a coating die head gasket, comprising:

[0007] A positioning substrate, wherein the positioning substrate is provided with a reference surface parallel to the coating die head gasket, and the reference surface is provided with a positioning pin for connecting with the coating die head gasket;

[0008] A positioning support plate is located at one end of the positioning base plate and is provided with an overlap surface that fits with the lip of the coating die head, and the overlap surface is perpendicular to the reference surface.

[0009] In the embodiment of the present application, before the coating die head gasket is clamped between the upper and lower coating dies, the positioning pins on the positioning substrate are first connected to the positioning holes on the coating die head gasket.

[0010] Then the coating die head gasket is installed between the upper and lower coating die heads, and the coating die head gasket and the coating die head are positioned with high precision by fitting the overlapping surface of the positioning plate with the coating die head lip of any coating die head.

[0011] After the coating die head gasket and the coating die head are positioned with high precision by using the quantitative adjustment device, the coating die head gasket is kept inwardly retracted inside the coating die head lip at a set size, thereby improving the installation accuracy and efficiency of the coating die head gasket and reducing the difficulty of manual positioning.

[0012] In some embodiments: the positioning pin is a cylindrical pin, at least two positioning pins are provided and are spaced apart from each other, and the coating die head gasket is provided with positioning holes that are compatible with the positioning pins.

[0013] In some embodiments: the distance between the positioning hole and the front end surface of the coating die head gasket is smaller than the distance between the positioning pin and the overlapping surface.

[0014] In some embodiments: the height of the positioning pin protruding from the reference plane is not greater than the thickness of the coating die gasket.

[0015] In some embodiments: the positioning substrate and the positioning support plate are integrally formed structures of metal materials, and the side of the positioning support plate away from the overlapping surface smoothly transitions with the positioning substrate through an arc.

[0016] In some embodiments: one end of the positioning plate away from the positioning substrate is provided with a barb extending obliquely toward the positioning substrate.

[0017] In some embodiments: the positioning substrate is a rectangular structure, and the positioning support plate is located at one end of the positioning substrate and extends along the width direction of the positioning substrate.

[0018] In some embodiments: a square piece is provided on the outer periphery of the coating die gasket, a through hole is opened on the square piece, and a positioning column adapted to the through hole is provided on the coating die.

[0019] In some embodiments: the thickness of the square sheet is the same as the thickness of the coating die gasket.

[0020] In some embodiments: the positioning pin includes a tapered section and a constant diameter section connected to each other, and the constant diameter section is fixedly connected to the positioning substrate.

[0021] The beneficial effects of the technical solution provided by this application include:

[0022] An embodiment of the present application provides a quantitative adjustment device for a coating die gasket. Since the quantitative adjustment device for a coating die gasket of the present application is provided with a positioning substrate, the positioning substrate is provided with a reference plane parallel to the coating die gasket, and a positioning pin for connecting with the coating die gasket is provided on the reference plane; a positioning support plate, the positioning support plate is located at one end of the positioning substrate, and is provided with a lap joint surface that is in contact with the lip of the coating die, and the lap joint surface and the reference plane are perpendicular to each other.

[0023] Therefore, before the coating die gasket is clamped between the upper and lower coating dies, the present application first uses the positioning pins on the positioning substrate to connect with the positioning holes on the coating die gasket. Then the overlapping surface of the quantitative adjustment device is fitted with the coating die lip of a coating die, so as to pre-fix the relative position of the coating die gasket and the coating die. Again, after the coating die gasket is installed on the above-mentioned coating die, the quantitative adjustment device is removed. Finally, another coating die and the above-mentioned coating die with the coating die gasket installed are connected to each other and then clamped. In this way, the requirements for the proficiency of personnel in installing the coating die gasket are reduced, and at the same time, the probability of coating quality problems due to installation problems is reduced, and the production cost is effectively reduced.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] The embodiment of the present application provides a quantitative adjustment device for a coating die head gasket, which can solve the problem in the related art that the die head gasket installation error is large, resulting in the coating size and surface density not meeting the process requirements.

[0034] See also Figures 1 to 4 As shown, the embodiment of the present application provides a quantitative adjustment device for coating a die head gasket, and the quantitative adjustment device 30 includes:

[0035] The positioning substrate 31 is provided with a reference surface 33 which is parallel to the coating die head gasket 20 , and a positioning pin 35 which is connected to the coating die head gasket 20 is provided on the reference surface 33 .

[0036] The positioning plate 32 is fixed to one end of the positioning base plate 31 . The positioning plate 32 is provided with an overlap surface 34 which is in contact with the coating die lip 11 . The overlap surface 34 and the reference surface 33 are perpendicular to each other.

[0037] Since the coating die gasket 20 is clamped between the upper and lower coating dies 10 and retracted inside the coating die lip 11 , a coating slit is formed between the coating die gasket 20 and the coating die lips 11 of the upper and lower coating dies 10 .

[0038] In the embodiment of the present application, before the coating die gasket 20 is clamped between the upper and lower coating dies 10, the positioning pin 35 on the positioning substrate 31 is first connected to the positioning hole 21 on the coating die gasket 20. Then, the overlapping surface 34 of the quantitative adjustment device 30 and the coating die lip 11 of a coating die 10 are fitted to achieve high-precision positioning, thereby pre-fixing the relative position of the coating die gasket 20 and this coating die 10. Again, after the coating die gasket 20 is installed on the above-mentioned coating die 10, the quantitative adjustment device 30 is removed. Finally, another coating die 10 and the above-mentioned coating die 10 with the coating die gasket 20 installed are connected to each other and clamped.

[0039] The coating die gasket 20 and the coating die 10 are first pre-positioned with high precision using the quantitative adjustment device 30, and then the coating die gasket 20 and the coating die 10 are installed, so as to keep the coating die gasket 20 inwardly retracted within the coating die lip 11 at a set size, thereby improving the installation accuracy and efficiency of the coating die gasket 20 and reducing the difficulty of manual positioning.

[0040] In some alternative embodiments: See Figures 3 to 5 As shown, an embodiment of the present application provides a quantitative adjustment device for a coating die head gasket. The positioning pin 35 of the quantitative adjustment device 30 is preferably but not limited to a cylindrical pin. There are at least two positioning pins 35 and they are spaced apart from each other. A positioning hole 21 that is compatible with the positioning pin 35 is opened on the coating die head gasket 20.

[0041] The distance between the positioning hole 21 and the front end surface of the coating die gasket 20 (i.e., the surface close to the coating die lip 11) of the embodiment of the present application is smaller than the distance between the positioning pin 35 and the lap surface 34. In this way, when the coating die gasket 20 is positioned and installed by using the quantitative adjustment device 30, the coating die gasket 20 can be retracted into the coating die lip 11 according to the set size.

[0042] Furthermore, the distance between the positioning hole 21 and the front end surface of the coating die gasket 20 (i.e., the side close to the coating die lip 11) and the distance between the positioning pin 35 and the lap surface 34 can be adjusted according to the actual inward shrinkage requirement of the coating die gasket 20 relative to the coating die lip 11.

[0043] The embodiment of the present application has three positioning pins 35, and the corresponding coating die head gasket 20 also has three positioning holes 21. The three positioning pins 35 and the three positioning holes 21 are arranged in a herringbone structure to prevent the coating die head gasket 20 from changing position in the quantitative adjustment device 30.

[0044] In some alternative embodiments: See Figure 3 and Figure 5As shown, an embodiment of the present application provides a quantitative adjustment device for a coating die gasket, wherein the height of a positioning pin 35 of the quantitative adjustment device 30 protruding from a reference plane 33 is not greater than the thickness of the coating die gasket 20, and preferably the height of the positioning pin 35 protruding from the reference plane 33 is the same as the thickness of the coating die gasket 20.

[0045] The positioning substrate 31 and the positioning support plate 32 are integrally formed structures of metal materials. The side of the positioning support plate 32 facing away from the lap surface 34 is smoothly transitioned to the positioning substrate 31 through an arc to remove burrs between the positioning substrate 31 and the positioning support plate 32, making it convenient to hold the quantitative adjustment device 30 to position and install the coating die head gasket 20.

[0046] In some alternative embodiments: See Figure 3 and Figure 5 As shown, an embodiment of the present application provides a quantitative adjustment device for a coating die gasket, and a positioning support plate 32 of the quantitative adjustment device 30 is provided with a barb 36 extending obliquely toward the positioning substrate 31 at one end thereof. The barb 36 is used to prevent the quantitative adjustment device 30 from falling off the coating die lip 11 when positioning the coating die gasket 20.

[0047] The positioning substrate 31 is preferably but not limited to a rectangular flat plate structure. The positioning support plate 32 is located at one end of the positioning substrate 31 and extends along the width direction of the positioning substrate 31. The positioning substrate 31 and the positioning support plate 32 are interconnected to form an "L"-shaped structure, which is convenient for the processing and manufacturing of the quantitative adjustment device 30.

[0048] In some alternative embodiments: See Figure 5 As shown, an embodiment of the present application provides a quantitative adjustment device for a coating die gasket, wherein the outer periphery of the coating die gasket 20 positioned by the quantitative adjustment device 30 is provided with a square piece 22 , and the thickness of the square piece 22 is the same as the thickness of the coating die gasket 20 .

[0049] A through hole 23 is formed on the square sheet 22 , and a positioning column matched with the through hole 23 is formed on the coating die 10 . The coating die gasket 20 and the coating die 10 are assembled by assembling the through hole 23 and the positioning column.

[0050] In some alternative embodiments: See Figure 3 and Figure 4 As shown, the embodiment of the present application provides a quantitative adjustment device for a coating die head gasket, wherein the positioning pin 35 of the quantitative adjustment device 30 includes a conical section and a constant diameter section connected to each other, and the constant diameter section is fixedly connected to the positioning substrate 31. The diameter of the constant diameter section is equal to the inner diameter of the positioning hole 21, and the diameter of the conical section is slightly smaller than the inner diameter of the positioning hole 21, so as to facilitate the positioning pin 35 to be inserted into the positioning hole 21.

[0051] How it works

[0052] The embodiment of the present application provides a quantitative adjustment device for a coating die gasket. Since the quantitative adjustment device for a coating die gasket of the present application is provided with a positioning substrate 31, the positioning substrate 31 is provided with a reference plane 33 which is parallel to the coating die gasket 20, and a positioning pin 35 which is connected to the coating die gasket 20 is provided on the reference plane 33; a positioning support plate 32, the positioning support plate 32 is located at one end of the positioning substrate 31, and is provided with a lap surface 34 which is in contact with the coating die lip 11, and the lap surface 34 is perpendicular to the reference plane 33.

[0053] Therefore, before the coating die gasket 20 is clamped between the upper and lower coating dies 10, the present application first uses the positioning pin 35 on the positioning substrate 31 to connect with the positioning hole 21 on the coating die gasket 20. Then the overlapping surface 34 of the quantitative adjustment device 30 is fitted with the coating die lip 11 of a coating die 10 to pre-fix the relative position of the coating die gasket 20 and the coating die 10. Again, after the coating die gasket 20 is installed on the above-mentioned coating die 10, the quantitative adjustment device 30 is removed. Finally, another coating die 10 and the above-mentioned coating die 10 with the coating die gasket 20 already installed are connected to each other and then clamped. The present application reduces the requirements for the installation proficiency of personnel, and at the same time reduces the probability of coating quality problems due to installation problems, effectively reducing production costs.
