Description

Technical Field

[0001] This utility model belongs to the technical field of special equipment for ceramic capacitor manufacturing, and specifically relates to a light source vision device. Background Technology

[0002] Multilayer ceramic capacitors (MLCCs), also known as surface mount capacitors, are manufactured by applying ceramic slurry onto a carrier film (PET film) through the injection port of a casting machine. The film is then dried in an oven to produce a ceramic film with a certain thickness, strength, and uniform density. The casting state of the ceramic slurry on the carrier film before drying directly affects the quality of the resulting ceramic film. In related technologies, the drying equipment disclosed in CN115732230A and CN207797649U involves directly drying the slurry in an oven / drying chamber after coating, which is not conducive to timely inspection of the slurry coating state on the carrier film and detection of coating defects. Therefore, it is necessary to provide a device that can inspect the ceramic slurry coating state and defects in real time during the ceramic film preparation process. Utility Model Content

[0003] The purpose of this invention is to provide a device that can inspect the coating status and defects of ceramic slurry in real time during the preparation of ceramic films.

[0004] To achieve the above objectives, the technical solution specifically provided by this utility model is as follows:

[0005] A light source vision device is disposed on the frame of a casting and drying equipment and located between the slurry casting unit and the drying unit, comprising:

[0006] A cold light source is installed on the top surface of the rack;

[0007] The light-transmitting panels are spaced parallel to the top surface of the frame and positioned above the cold light source;

[0008] The enclosure is mounted on the frame, and a pair of side plates of the enclosure have through slots for the carrier film to pass through, and the top cover or at least one side plate of the enclosure is a transparent plate; the cold light source and the light-transmitting plate are both located inside the enclosure.

[0009] By adopting the above technical solution, after the slurry is coated onto the carrier film in the casting unit, it sequentially passes through the through-grooves on opposite sidewalls of the cover along with the carrier film, and then enters the drying unit for drying. The light-transmitting plate supports the carrier film as it passes through the cover. Light emitted from the cold light source passes through the light-transmitting plate and illuminates the back side of the carrier film. At this time, the operator can easily visually inspect the casting state of the ceramic slurry using the transparent plate, enabling timely detection of production defects and adjustment of equipment operating parameters based on observations. The cover also allows the carrier film to operate in a relatively enclosed environment, significantly reducing the possibility of external impurities contaminating the incompletely cured ceramic slurry. Simultaneously, the selection of a cold light source minimizes the negative impact of heat generated by the light source on the ceramic film.

[0010] It should be noted that, in this application, "cold light source" refers to a light source whose light-emitting principle does not rely on high temperatures, whose own temperature is relatively low during light emission, and whose spectrum contains a low proportion of infrared radiation. The light emission of a "cold light source" does not occur through heating the filament to incandescence (thermal radiation) like an incandescent lamp, but rather through other physical mechanisms (such as electroluminescence, photoluminescence, chemiluminescence, etc.). Compared to hot light sources such as incandescent and halogen lamps with equivalent light output, their temperature during light emission is much lower; the proportion of invisible infrared radiation (heat) in the light they emit is very small, with most of the energy concentrated in the visible light range, resulting in less heat absorption by the object when it shines on it. Therefore, the negative impact of heat generation from the light source on the ceramic film can be minimized.

[0011] Furthermore, the cover includes a rectangular frame and a cover hinged to the frame; the frame is formed by a pair of long side plates and a pair of short side plates, with a through slot in the long side plate, and the cover is hinged to one of the short side plates. The cover can be rotated to open and close, facilitating maintenance and cleaning operations.

[0012] Furthermore, the cover includes a top frame and side frames that are perpendicular to each other, and transparent plates are installed on both the top frame and the side frames; a slot is opened on the short side plate on one side of the cover for the side frame to be inserted. This increases the visible area, reduces blind spots, and makes it easier to inspect the flow state of the ceramic slurry.

[0013] Furthermore, the width of the side frame away from the top frame is greater than the thickness of the short side plate, and the top surface of the frame is provided with several elastic supports for supporting the side frames. The elastic supports can act as a buffer when the cover is fastened, reducing noise generated during the cover fastening process.

[0014] Furthermore, the elastic support is a rubber block fixedly installed on the frame.

[0015] Furthermore, the top frame is mounted to the short side plate via hinges on its outer edge away from the side frame, and a gas spring is provided between the short side plate and the top frame.

[0016] Furthermore, the light-transmitting plate is a glass plate, which has good light transmittance and is more conducive to visual inspection of the ceramic slurry casting state.

[0017] Furthermore, two light-transmitting plates are arranged at parallel intervals.

[0018] Furthermore, the light-transmitting plate is installed using mounting components at its four corners; each mounting component includes pads, connecting rods, and pressure blocks fixed to the frame; the light-transmitting plate has through holes for the connecting rods to pass through; the connecting rods are connected to the pads and pressure blocks at their respective ends. This installation method allows for easy disassembly of the light-transmitting plate, especially when the cold light source needs to be replaced, repaired, or cleaned.

[0019] Furthermore, the top surface of the pad has a recessed groove, and a floating element is located within the groove. An elastic element is provided between the floating element and the bottom wall of the groove. The floating element and the elastic element help to keep the light-transmitting plate stable. This installation method can eliminate the shaking of the light-transmitting plate caused by factors such as dimensional deviations and installation allowances, which is conducive to the smoother operation of the carrier film and the production of high-quality ceramic films.

[0020] Furthermore, the light-transmitting plate is flush with the lower edge of the through groove. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the present application will be further described in detail below with reference to the accompanying drawings.

[0033] [Example 1]

[0034] A light source vision device, referring to Figure 1 and Figure 2 It is installed on the frame 1 of the casting and drying equipment, and located between the slurry casting unit 12 and the drying unit 13 (e.g., Figure 7 The system includes a cold light source 2, a light-transmitting plate 3, and a cover 4 that covers the cold light source 2 and the light-transmitting plate 3.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The cold light source 2 is a lamp panel embedded in the top surface of the frame 1. In this embodiment, an LED lamp panel is selected, which emits white light after being powered on. The light-transmitting plate 3 is a transparent glass plate, which is fixedly installed by the mounting assembly 6. It is parallel to the cold light source 2 and spaced apart from the cold light source 2. The white light emitted by the cold light source 2 can pass through the light-transmitting plate 3.

[0036] Reference Figure 1 , Figure 2 and 4The cover 4 comprises a frame 41 fixed to the frame 1 and a cover 42 hinged to the frame 41. The frame 41 is rectangular, formed by a pair of long side plates 411 and a pair of short side plates 412 joined together at their ends. The two long side plates 411 are positioned opposite each other, and each long side plate 411 has a rectangular through slot 4111 for the carrier film to pass through. The two short side plates 412 are also positioned opposite each other. The cover 42 is hinged to the top of one of the short side plates 412. A pair of gas springs 43 located inside the cover 4 are positioned between the short side plate 412 and the cover 42. One end of each gas spring 43 is hinged to the short side plate 412, and the other end is hinged to the cover 42, allowing the cover 42 to be supported when it is rotated open.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The cover 42 includes a top frame 421 and a side frame 422 that are perpendicular to each other and fixedly connected. A short frame on one side of the top frame 421 is hinged to a short side plate 412, and the movable end of a gas spring 43 is hinged to a triangular protrusion in the middle of the long frame of the top frame 421. A transparent plate 423 is installed inside the top frame 421, allowing observation of the ceramic slurry casting process on the carrier film inside the cover 4 from the top of the cover 4.

[0038] Reference Figure 1 , Figure 2 and Figure 4 Another short side plate 412 has a slot 4221 for the side frame 422 to be inserted into, and the slot 4221 extends to the top of the short side plate 412 to form an opening. A transparent plate 423 is also installed inside the side frame 422, so the inside of the cover 4 can also be visually inspected from the side frame 422.

[0039] Reference Figure 2 , Figure 3 and Figure 4 The width of the side frame 422 away from the top frame 421 is greater than the thickness of the side short plate, and extends inward towards the cover 4. A pair of elastic support members 5 are provided at the top of the frame 1. In this embodiment, the elastic support members 5 are all fixed rubber blocks. When the cover 42 is closed, the top of the elastic support member 5 abuts against the side frame 422. A handle 4222 is provided on the outer side of the side frame 422 to facilitate opening / closing the cover 42. When the cover 42 is closed, noise is not easily generated under the support of the elastic support members 5.

[0040] Reference Figure 4 and Figure 5The top surface of the light-transmitting plate 3 is flush with the lower edge of the through groove 4111. Four sets of mounting components 6 are provided, located at the four corners of the light-transmitting plate 3. The mounting components 6 include a cylindrical pad 61 fixed to the top surface of the frame 1, with a connecting rod 62 coaxially fixed to the top surface of the pad 61. The diameter of the connecting rod 62 is smaller than the diameter of the pad 61. A through hole 4231 is opened on the light-transmitting plate 3 for the connecting rod 62 to pass through. A pressure block 63 is fixedly connected to the top of the connecting rod 62. In this embodiment, the pressure block 63 is cylindrical, and a connecting screw 631 is fixed to its bottom surface. The connecting screw 631 is threadedly connected to the connecting rod 62. This method of installing the light-transmitting plate 3 is simple and convenient, and the light-transmitting plate 3 is secure and stable after installation.

[0041] The working principle of this embodiment is as follows: After the slurry is cast onto the surface of the carrier film, the carrier film loaded with slurry passes through the through-groove 4111 and through the cover 4. The light-transmitting plate 3 supports the movement of the carrier film. The cold light source 2 emits light that illuminates the slurry from the back. At this time, the slurry casting status on the carrier film can be visually inspected in the transparent plate 423 area of ​​the cover 4, and defects such as air bubbles and uneven casting can be detected in time. The operator can adjust the equipment operating parameters in time based on the observed situation. The cover 42 includes two transparent plates 423, which maximizes the field of view and reduces blind spots, making it easier to inspect the slurry casting status. At the same time, the cover 42 is designed to be openable and closable, which facilitates disassembly, assembly, and cleaning. When inspecting the slurry casting status, keeping the cover 42 in the locked state can prevent external debris from contaminating the slurry.

[0042] [Example 2]

[0043] Based on the requirements for ceramic capacitor fabrication, the resulting ceramic diaphragm needs to be as smooth and uniform as possible, which correspondingly necessitates maximizing the stability of the equipment. Given the mounting method of the light-transmitting plate 3, it may experience slight wobbling during operation due to a certain installation allowance. This embodiment, based on Embodiment 1, further optimizes the mounting method of the light-transmitting plate 3, retaining its ease of assembly and disassembly while improving installation stability, thus minimizing any adverse effects on the ceramic diaphragm fabrication.

[0044] Reference Figure 6In this embodiment, an annular groove 611, coaxial with the connecting rod 62, is formed on the top surface of the pad 61. A floating member 64, made of rubber, is provided within the groove 611. An elastic member 65, in this embodiment a compression spring, is provided between the bottom surface of the floating member 64 and the bottom wall of the groove 611. After the light-transmitting plate 3 is installed, the floating member 64 tends to float upwards under the action of the elastic member 65, thus pressing against the bottom surface of the light-transmitting plate 3. Under the combined action of the elastic member 65, the floating member 64, and the pressure block 63, the vibration, shaking, or swaying of the light-transmitting plate 3 is suppressed to the greatest extent, allowing it to support the carrier film in a stable state, which is beneficial for preparing high-quality ceramic films. In other embodiments, an elastic pad can also be provided on the bottom surface of the pressure block 63 to further improve the installation stability of the light-transmitting plate 3.

[0045] [Example 3]

[0046] Reference Figure 7 and Figure 8 This embodiment is based on embodiment 1, with the difference being that the cold light source 2 is installed in a different way and is equipped with a double-layer light-transmitting plate 3.

[0047] The cold light source 2 is mounted and fixed by a rectangular frame-shaped mounting bracket 16. The frame 1 of the light source vision device 15 has no top plate. The mounting bracket 16 has a rectangular frame 161 around its perimeter, with elongated mounting holes 162 on the frame 161. The frame 161 fits against the four side plates of the frame 1, and bolts are inserted through the mounting holes 162 to fix the mounting bracket 16. The cold light source 2 is plate-shaped and located on the bottom surface of the mounting bracket 16, with its main body located in the hollow space of the mounting holes 162. Several L-shaped hooks 163 are fixed on the back of the mounting bracket 16, and the cold light source 2 is fixed between the L-shaped hooks 163 and the bottom surface of the mounting bracket 16. The mounting assembly 6 for fixing the light-transmitting plate 3 and the elastic support 5 for supporting the cover 42 are both located on the top surface of the mounting bracket 16.

[0048] In this embodiment, two light-transmitting plates 3 are provided, which are parallel to each other and form a gap for the carrier film to pass through. The two layers of light-transmitting plates 3 are spaced apart, which does not affect the transmission of light and does not hinder visual inspection.
