Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic spraying technology, specifically a spraying device for alumina electronic ceramics. Background Technology
[0002] Alumina electronic ceramics are ceramic materials with alumina (Al2O3) as the main component. They are widely used in the electronics industry. Alumina electronic ceramics have high melting point, high hardness, excellent electrical insulation properties and thermal stability. These characteristics make them play an important role in electronic devices.
[0003] Spray coating can form a wear-resistant coating on the surface of the substrate, thereby better protecting the internal substrate and reducing the impact of friction damage during use. However, during spraying, the ceramic substrate needs to be positioned first. Existing positioning mechanisms are generally clamped on the surface of the substrate, especially when clamping and spraying tubular ceramic substrates, which will affect the uniformity of spraying on the surface of the ceramic substrate and affect the overall spraying effect. Therefore, further improvements can be made. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides the following technical solution: a spraying device for alumina electronic ceramics, comprising a cabinet, a cabinet door hinged to the front of the cabinet, a partition fixedly installed inside the cabinet, a control box located inside the cabinet and below the partition, a rotating seat fixedly installed at the center of the top side of the partition, a support and positioning component for positioning a cylindrical ceramic substrate from the inside being provided on the top of the rotating seat, and uniform spraying components for spraying being provided on the left and right inner walls and the back wall of the cabinet.
[0005] As an optimization, the support positioning assembly includes a fixed cylinder fixedly installed at the top center of the rotating seat. A screw is rotatably connected inside the fixed cylinder. A geared motor is fixedly installed inside the rotating seat, and the bottom end of the screw is connected to the output end of the rotating seat through a coupling. A lifting ring is slidably connected inside the fixed cylinder, and the screw is screwed into the lifting ring. Support plates are fixedly installed in an array on the outer side of the lifting ring. An expandable and retractable support member is provided between the support plate and the top end of the fixed cylinder. By starting the geared motor, the screw will rotate inside the lifting ring, which will in turn drive the support plate to rise and fall with the lifting ring, thus causing the support member to expand or retract.
[0006] As an optimization, the outer side of the fixed cylinder is provided with four sliding grooves, and the support plate is slidably connected in the sliding grooves.
[0007] As an optimization, the support includes supports fixedly installed on the top side of the support plate and the outer side of the top of the fixed cylinder. Rotating plates are rotatably connected inside both supports, and the rotating plates on both sides are symmetrically arranged. Abutment plates are hinged to the ends of the rotating plates on both sides. Rubber pads are fixedly installed on the outer side of the abutment plates, and a balancer is provided between the rotating plates on both sides to maintain their balance. The support plate is raised and lowered by the lifting ring, which pushes and pulls the rotating plate on one side, thus supporting the abutment plate to expand or contract outward.
[0008] As an optimization, the balancing component includes a support rod that is slidably inserted between the two rotating plates, with rotating columns rotatably connected to both ends of the support rod. A slide rail is provided in the middle of the rotating plate, and the rotating columns are rotatably connected within the slide rail.
[0009] As an optimization, the uniform spraying assembly includes a slide rail fixedly installed on the inner wall of the cabinet. A reciprocating lead screw is rotatably connected inside the slide rail, and a reciprocating slider is slidably connected inside the slide rail. The reciprocating slider is sleeved on the outside of the reciprocating lead screw. A connector is fixedly installed at the center of one side of the front of the reciprocating slider. Feed hoses are inserted into both sides of the connector. A spray head is fixedly installed at the center of the front of the connector.
[0010] The beneficial effects of this utility model are:
[0011] 1. The alumina electronic ceramic spraying device uses a screw that rotates inside a lifting ring, which in turn drives a support plate to rise and fall with the lifting ring. This pushes and pulls a rotating plate on one side, causing the support plate to expand outward. This, in turn, causes a rubber pad to press against the inner wall of the cylindrical ceramic substrate for positioning and support. This facilitates positioning of the ceramic substrate from the inside, preventing the ceramic substrate from being partially unsprayable due to external clamping and positioning, thus improving the spraying quality.
[0012] 2. This alumina electronic ceramic spraying device uses a reciprocating screw that rotates inside a reciprocating slider. This causes the reciprocating slider to slide up and down along the inner wall of the slide rail, which in turn drives the spray head to spray the ceramic substrate located in the center evenly. Furthermore, the rotating seat also drives the ceramic substrate to rotate, thus enabling uniform spraying of the ceramic substrate from all directions and improving the spraying effect.

[0018] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 A spraying device for alumina electronic ceramics includes a cabinet 1, a cabinet door 2 hinged to the front of the cabinet 1, a partition 3 fixedly installed inside the cabinet 1, a control box 4 located inside the cabinet 1 and below the partition 3, a rotating seat 5 fixedly installed at the center of the top side of the partition 3, a support and positioning component 6 for positioning a cylindrical ceramic substrate from the inside is provided on the top of the rotating seat 5, and uniform spraying components 7 for spraying are provided on the left and right inner walls and the back wall of the cabinet 1.
[0021] Please see Figure 2-3The support positioning component 6 includes a fixed cylinder 8 fixedly installed at the top center of the rotating seat 5. A screw 9 is rotatably connected inside the fixed cylinder 8. A geared motor is fixedly installed inside the rotating seat 5, and the bottom end of the screw 9 is connected to the output end of the rotating seat 5 through a coupling. A lifting ring is slidably connected inside the fixed cylinder 8, and the screw 9 is screwed into the lifting ring. A support plate 10 is fixedly installed on the outer side of the lifting ring. An expandable and retractable support member is provided between the support plate 10 and the top end of the fixed cylinder 8. By starting the geared motor, the screw 9 will rotate inside the lifting ring, which will in turn drive the support plate 10 to move up and down with the lifting ring. Therefore, the support member will expand or retract, which will facilitate supporting the cylindrical ceramic substrate from the inside or retracting it to remove it.
[0022] Please see Figure 2-3 The outer side of the fixed cylinder 8 is provided with four sliding grooves, and the support plate 10 is slidably connected in the sliding grooves. The sliding of the support plate 10 in the sliding grooves restricts the lifting ring, preventing the lifting ring from rotating with the screw 9 and thus preventing it from lifting.
[0023] Please see Figure 2-3 The support includes a support fixedly installed on the top side of the support plate 10 and the outer side of the top of the fixed cylinder 8. A rotating plate 11 is rotatably connected inside the support on both sides, and the rotating plates 11 on both sides are symmetrically arranged. A stop plate 12 is hinged to the end of the rotating plate 11 on both sides. A rubber pad 13 is fixedly installed on the outer side of the stop plate 12, and a balance member is provided between the rotating plates 11 on both sides to maintain their balance. The support plate 10 is raised and lowered by the lifting ring, which pushes and pulls the rotating plate 11 on one side. Therefore, the stop plate 12 is supported to expand or contract outward. When it is supported and expanded, the rubber pad 13 will be driven to press against the inner wall of the cylindrical ceramic substrate for positioning support. When it is contracted, it will no longer provide positioning support for the cylindrical ceramic substrate, making it easy to remove.
[0024] Please see Figure 2-3 The balancing component includes a support rod 14 that is slidably inserted between two rotating plates 11. Both ends of the support rod 14 are rotatably connected to rotating columns 15. A slide rail 16 is provided in the middle of the rotating plate 11, and the rotating columns 15 are rotatably connected in the slide rail 16. When the rotating plate 11 is pushed or pulled and deflected, the rotating columns 15 will roll along the inner wall of the slide rail 16, thereby ensuring that the support rod 14 can stably maintain the balance of the two rotating plates 11.
[0025] Please see Figure 4The uniform spraying component 7 includes a slide rail 17 fixedly installed on the inner wall of the cabinet 1. A reciprocating screw 18 is rotatably connected inside the slide rail 17, and a reciprocating slider 19 is slidably connected inside the slide rail 17. The reciprocating slider 19 is sleeved on the outside of the reciprocating screw 18. A connector 20 is fixedly installed at the center of one side of the front of the reciprocating slider 19. Feed hoses 21 are inserted into both sides of the connector 20. A nozzle 22 is fixedly installed at the center of the front of the connector 20. By rotating the reciprocating screw 18 inside the reciprocating slider 19, the reciprocating slider 19 will slide up and down along the inner wall of the slide rail 17, thereby driving the nozzle 22 to uniformly spray the ceramic substrate located in the center.
[0026] When in use, first, the ceramic substrate that needs to be sprayed is placed on the outside of the support and positioning component 6. Then, by starting the reduction motor, the screw 9 is driven to rotate inside the lifting ring, which will drive the support plate 10 to rise and fall with the lifting ring, that is, push and pull the rotating plate 11 on one side, so the abutment plate 12 is supported and expanded outward, which will drive the rubber pad 13 to press against the inner wall of the cylindrical ceramic substrate for positioning and support.
[0027] Then, the reciprocating screw 18 rotates inside the reciprocating slider 19, which causes the reciprocating slider 19 to slide up and down along the inner wall of the slide rail 17, thereby driving the nozzle 22 to spray the ceramic substrate located in the center evenly. Furthermore, the rotating seat 5 will also drive the ceramic substrate to rotate, thus enabling the ceramic substrate to be sprayed evenly from all directions.
[0028] Similarly, when the screw 9 is rotated in the opposite direction by the geared motor, the abutment 12 can be retracted inward, thus eliminating the need for positioning and support of the cylindrical ceramic substrate, making it easy to remove the ceramic substrate after spraying.
[0029] In summary, the alumina electronic ceramic spraying device uses a screw 9 that rotates inside a lifting ring, which in turn causes the support plate 10 to move up and down with the lifting ring. This pushes and pulls the rotating plate 11 on one side, thus lifting the abutment plate 12 and expanding it outward. This causes the rubber pad 13 to press against the inner wall of the cylindrical ceramic substrate for positioning and support, thereby facilitating the positioning of the ceramic substrate from the inside and preventing the ceramic substrate from being partially uncoated due to external clamping and positioning, thus improving the spraying quality.
[0030] The reciprocating screw 18 rotates inside the reciprocating slider 19, causing the reciprocating slider 19 to slide up and down along the inner wall of the slide rail 17. This, in turn, drives the spray head 22 to spray the ceramic substrate located in the center evenly. Furthermore, the rotating seat 5 also drives the ceramic substrate to rotate, thus enabling the ceramic substrate to be sprayed evenly from all directions, improving the spraying effect.
