Description

Technical Field

[0001] This utility model relates to the technical field of coating machines and coating machine accessories, specifically to a die lip detection device. Background Technology

[0002] As a precision wet coating technology, its working principle involves the slurry being extruded and transferred onto the substrate through the slit of a coating die under a certain pressure and flow rate. Compared to other coating methods, it has many advantages, such as fast coating speed, high precision, and uniform wet thickness; the coating system is closed, preventing contaminants from entering during the coating process; it has high slurry utilization and can maintain the stability of slurry properties; it can perform multi-layer coating simultaneously and can adapt to different slurry viscosities and solid content ranges. The coating die mainly consists of an upper die, a lower die, a gasket, and an adjustment device. The gasket sandwiched between the upper and lower dies forms a slit and a lip communicating with the slit. The slurry is uniformly coated onto the substrate through the slit and the lip. During the coating process, the misalignment of the upper and lower lips and the inward retraction of the gasket have a significant impact on the coating quality. Figure 1 As shown, there are usually situations such as the upper lip protruding, the lower lip protruding, the upper and lower lips crossing, or the gasket shrinking inward (from left to right in the figure). Therefore, it is usually necessary to use a lip detection device to detect the amount of misalignment of the mold head and the amount of gasket shrinkage.

[0003] In related technologies, lip detection devices generally include a fixture and a laser sensor mounted on the fixture. The fixture is clamped at the lip of the coating die head, and then the laser sensor is used for detection. To ensure detection accuracy, it is generally necessary to manually move the position of the fixture at the lip along the length of the coating die head and perform multiple detections at multiple positions. This requires repeated disassembly and assembly, which is time-consuming, labor-intensive, and results in low production efficiency. Utility Model Content

[0038] The following is combined with Figures 2 to 10 The following describes embodiments of the present invention.

[0039] According to an embodiment of the present invention, a mold head lip detection device is provided, comprising: a detection platform 1 for placing a mold head 2 for detection along a first horizontal direction; a driving component disposed on the detection platform 1; and a scanning component 3 connected to the driving end of the driving component and driven by the driving component to move along the first horizontal direction for scanning and imaging the lip of the mold head 2.

[0040] It should be noted that the stroke length of the drive end of the drive component is greater than the length of the mold head 2.

[0041] In this embodiment, by setting a driving component on the detection platform 1 and a scanning component at the driving end of the driving component, when it is necessary to detect the lip of the mold head 2, the mold head 2 is placed on the detection platform 1 along the first direction, so that the moving direction of the mold head 2 and the scanning component 3 are parallel, and the position of the scanning end of the scanning component 3 corresponds to the lip of the mold head 2. Then, the scanning component 3 and the driving component are started, so that the driving component drives the scanning component to move along the first direction to scan and image the lip of the mold head 2, scanning out the contours of the upper mold lip, the gasket, and the lower mold lip, and calculating the relative position data of the three through a predetermined program, thereby detecting the misalignment of the mold head 2 and the inward shrinkage of the gasket. The scanning is automated, the scanning data is accurate, and the repeatability is high. The predetermined detection position can be set through the driving component according to actual needs, and the entire process can be scanned, reducing the dependence on workers with specific skills, saving time and labor, and improving production efficiency. It can be applied to the detection of single-layer mold heads 2 as well as double-layer mold heads 2, with a wide range of applications.

[0042] Specifically, testing platform 1 is a marble platform to improve its service life.

[0043] In one embodiment, such as Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown, the driving end of the driving component is connected to the scanning element 3 via the displacement slide 4; the displacement slide 4 is located at the driving end of the driving component, and its adjustment end is connected to the scanning element 3, for driving the scanning element 3 to move in the second horizontal direction; the second horizontal direction is perpendicular to the first horizontal direction.

[0044] In this embodiment, the drive end of the drive component is connected to the scanning component via a displacement slide 4, which facilitates the adjustment of the scanning component in the second horizontal direction. This allows for the adjustment of the position of the scanning element 3 according to actual needs, ensuring precise alignment between the scanning element 3 and the lip of the mold head 2, thereby improving adjustment accuracy.

[0045] In one embodiment, such as Figure 8 and Figure 9As shown, the adjustment end of the displacement slide 4 is slidably connected to the first moving block 5 in the vertical direction; the first moving block 5 is provided with a first driving member 6; the driving end of the first driving member 6 is connected to the adjustment end of the displacement slide 4 and is used to drive the first moving block 5 to move in the vertical direction; the scanning member 3 is connected to the first moving block 5 through a connecting member.

[0046] In this embodiment, the adjustment end of the displacement slide 4 is connected to the scanning component 3 via the first moving block 5. The first moving block 5 can be driven to move vertically via the first driving component 6, which facilitates the adjustment of the scanning component in the vertical direction. This allows the position of the scanning component 3 to be adjusted according to actual needs, so that the scanning component 3 and the lip of the mold head 2 are precisely aligned, further improving the adjustment accuracy.

[0047] Specifically, such as Figure 8 and Figure 9 As shown, the first driving component 6 is a micrometer head, which is set in the vertical direction. The adjustment end of the micrometer head is rotatably connected to the adjustment end of the displacement slide 4 so as to make fine adjustments in the vertical direction and improve the adjustment accuracy.

[0048] Specifically, the displacement slide 4 includes a base, a second moving block, a second driving component, and a mounting base. The base has an adjustment end for the driving component, and the second moving block is slidably connected to the base along a second horizontal direction. The second driving component is located on the base, and its driving end is connected to the second moving block for driving the second moving block to move along the second horizontal direction. The mounting base is located on the second moving block, and the first moving block 5 is slidably connected to the mounting base. The second driving component can drive the second moving block to move in the second horizontal direction, facilitating the adjustment of the scanning component in the second horizontal direction. This allows for adjustment of the position of the scanning element 3 according to actual needs, ensuring precise alignment between the scanning element 3 and the lip of the mold head 2, thereby improving adjustment accuracy.

[0049] Specifically, the second driving component is a micrometer head, which is set along the second horizontal direction, and the adjustment end of the micrometer head is rotatably connected to the second moving block so as to make fine adjustments in the second horizontal direction and improve the adjustment accuracy.

[0050] In one embodiment, such as Figure 6 and Figure 8 As shown, the connecting part is a horizontal tooling block 7.

[0051] In this embodiment, the connector adopts a horizontally set horizontal tooling block 7, which can be used to connect the scanning part 3 when the mold head 2 is placed horizontally, so as to avoid the installation position of the scanning part 3 being too high and ensure that it is aligned with the lip of the mold head 2.

[0052] As a possible alternative implementation, it can also be, for example... Figure 7 and Figure 9 As shown, the connecting part is a vertical tooling block 8.

[0053] In this embodiment, the connector adopts a vertically arranged vertical tooling block 8, which can be used to connect the scanning part 3 when the mold head 2 is placed vertically. This can improve the installation position of the scanning part 3, and when connected, the scanning end of the scanning part 3 faces downward, which makes it easier for the scanning part 3 to be aligned with the lip of the mold head 2.

[0054] In one embodiment, such as Figure 5 As shown, the drive assembly includes a linear module 9, and the scanning element 3 is connected to the slide of the linear module 9.

[0055] In this embodiment, the driving component adopts a linear module 9, and the scanning element 3 is mounted on the slide of the linear module 9 to facilitate driving movement in the first horizontal direction.

[0056] In one embodiment, such as Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown, the drive assembly also includes a cable chain 10, which is disposed on the detection platform 1 along the first horizontal direction, and the free end of the cable chain 10 is connected to the slide table.

[0057] In this embodiment, a drag chain 10 is used to connect to the slide table, which improves the stability of the slide table during movement and ensures the detection accuracy.

[0058] In one embodiment, the scanner 3 is a 3D sensor.

[0059] In this embodiment, the scanning element 3 uses a 3D sensor, namely a 3D photoelectric sensor, to improve scanning accuracy.

[0060] In one embodiment, such as Figure 3 and Figure 10 As shown, the mold head lip detection device also includes: a plurality of positioning blocks 11, which are spaced apart on the detection platform 1 along the first horizontal direction and located on the side of the drive component close to the mold head 2, for positioning by abutting against the mold head 2.

[0061] In this embodiment, by setting a positioning block 11, the mold head 2 is placed on the detection platform 1, and the mold head 2 is limited by abutting against the positioning block 11, thereby achieving precise positioning, keeping it at a predetermined distance from the scanned part 3, and ensuring that it is set along the first horizontal direction, improving detection accuracy and facilitating installation.

[0062] In one embodiment, such as Figure 10 As shown, the mold head lip detection device also includes a fixing block 12. The mold head 2 has fixing blocks 12 on both sides of its length direction. The fixing block 12 has a first waist hole 13 along the vertical direction. The first waist hole 13 is connected to the lower mold of the mold head 2 by a first screw. The fixing block 12 has a second waist hole 14 along the first horizontal direction. The second waist hole 14 is connected to the detection platform 1 by a second screw.

[0063] In this embodiment, a fixing block 12 is set to connect the lower mold of the mold head 2 and the detection platform 1. The first waist hole 13 and the second waist hole 14 are set to facilitate appropriate adjustment during installation, improve the fault tolerance rate, and can be adapted to install mold heads 2 of different sizes, with a wide range of applications. Fixing the lower mold of the mold head 2 on the detection platform 1 facilitates scanning, and when the mold head 2 needs to be adjusted after the detection is completed, it is easy to disassemble the upper mold, thereby adjusting the position of the upper mold and the lower mold as well as the position of the shim.

[0064] Specifically, such as Figure 1 and Figure 2 As shown, the mold lip detection device also includes an electrical cabinet 15, which is electrically connected to the drive assembly and the scanning component 3 to provide power.

[0065] Specifically, the mold lip detection device also includes a protective cover 16, which is installed on the detection platform 1 and has an opening facing the mold 2, making it easy to install the mold 2 for detection; the bottom of the detection platform 1 is equipped with an electrical cabinet 15 and a storage cabinet, and the periphery of the installation cabinet is equipped with an exhaust vent 17, which can make the whole unit integrated and improve space utilization; the bottom of the detection platform 1 is equipped with casters 18 for movement and support legs 19 for fixing.

[0066] Specifically, such as Figure 1 As shown, the mold lip detection device also includes a controller, a display screen 20, and a mouse and keyboard assembly 21 and an execution button 22 for operation. The controller and the display screen 20 are both electrically connected to the electrical cabinet 15. The display screen 20 is mounted on the protective cover 16. The mouse and keyboard assembly 21, the execution button 22, the display screen 20, the drive assembly, and the scanning component 3 are all communicatively connected to the controller so that the scanning analysis results can be displayed on the display screen 20 for operation.

[0067] The specific working principle of the mold head lip detection device provided in this embodiment is as follows: When it is necessary to detect the lip of the mold head 2, the mold head 2 is placed on the detection platform 1 along the first direction, and the lower mold is fixed on the detection platform 1 on both sides by fixing blocks 12. The position of the 3D sensor is adjusted in the vertical direction and the second horizontal direction by the first driving member 6 and the second driving member, so that the scanning end of the 3D sensor is aligned with the lip of the mold head 2. Then, the scanning component is driven by the linear mold head 2 to move along the first direction to scan and image the lip of the mold head 2, scanning out the contours of the upper mold lip, the gasket, and the lower mold lip, and calculating the relative position data of the three through a predetermined program, thereby detecting the lip of the mold head 2. When there are problems with the misalignment of the die head 2 and the inward shrinkage of the gasket, adjustments can be made by disassembling the upper die based on the scanning results until it is qualified. The scanning data is accurate and has high repeatability. The predetermined detection position can be set according to actual needs through the drive component, or the entire process can be scanned. This reduces the dependence on workers with specific skills, saves time and labor, and improves production efficiency. It can be applied to the detection of single-layer die head 2 as well as double-layer die head 2. The working stroke of the linear module 9 can be adjusted according to the length of the die head 2. It has a wide range of applications and solves the problem that the existing lip detection device uses a clamp to hold the lip of the coating die head 2, which requires repeated disassembly and assembly during detection, which is time-consuming, labor-intensive, and has low production efficiency.

[0068] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
