The fixture includes a positioning frame and a mounting plate detachably installed within the positioning frame. It also includes: mounting holes arranged in a rectangular array on the mounting plate for placing ceramic substrates; each mounting hole has a clamping part for limiting the ceramic substrate's position.

Description

Technical Field

[0001] This utility model relates to the field of special ceramic processing technology, and in particular to a fixture for metallization printing of special ceramics. Background Technology

[0002] Ceramic substrates are electronic packaging materials made from high-performance ceramic materials using precision processes. They are mainly used to support, insulate, and dissipate heat from electronic components and are core basic materials in fields such as power electronics and semiconductor packaging.

[0003] Ceramic metallization can form metal lines such as copper, gold, and silver on the ceramic surface, enabling electrical connections between the chip and external circuits. It can also enhance the thermal conductivity of the ceramic substrate. The metallization layer can rapidly diffuse the heat source of the chip through the "chip-solder-metal layer-ceramic" path. Currently, metallization printing on ceramic substrates mostly adopts screen printing technology, in which metallic pigments are printed on the surface of the ceramic substrate. Ceramic substrates come in various shapes. In the processing of circular ceramic substrates, multiple sets of circular ceramic substrates are placed in a carrier for uniform printing.

[0004] In the existing technology, there are certain problems. When printing multiple sets of ceramic substrates in batches, they need to be uniformly loaded into a carrier for clamping and fixing. However, after printing, the operator needs to remove the substrates from the carrier one by one. The operation process is cumbersome and inefficient. In addition, during the printing process, the ceramic substrates are prone to displacement or shaking, which leads to a significant reduction in printing accuracy. Therefore, we urgently need a special fixture for ceramic metallization printing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of cumbersome material output and reduced printing accuracy due to shaking in the existing technology, and to propose a special ceramic metallization printing fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A special ceramic metallization printing fixture includes a positioning frame and a mounting plate that is detachably installed within the positioning frame. It further includes: mounting holes arranged in a rectangular array on the mounting plate for placing ceramic substrates; each of the mounting holes has a clamping part for limiting the position of the ceramic substrate; when the ceramic substrate is located within the mounting hole, the surface of the ceramic substrate is flush with the mounting hole; support plates symmetrically sliding on the positioning frame; uprights symmetrically installed on the bottom wall of the positioning frame; when two sets of support plates abut against the uprights, they form a support part for supporting the mounting plate; and rectangular rows of round rods arranged coaxially with the mounting holes on the bottom wall of the positioning frame; the ends of the round rods are fixedly connected to support rods; when the ceramic substrate is located within the mounting hole, the bottom of the ceramic substrate abuts against the support rods.

[0008] To clamp the ceramic substrate, preferably, the clamping part includes at least two sets of elastic sheets disposed on the inner wall of the placement hole. The end of the elastic sheet is fixedly connected to the inner wall of the placement hole, and the other end of the elastic sheet abuts against the inner wall of the placement hole. An anti-slip pad is fixedly connected to the elastic sheet. When the ceramic substrate is located in the placement hole, the anti-slip pad abuts against its outer wall to form a clamping area.

[0009] To further improve the clamping effect, the anti-slip pad is provided with anti-slip patterns, which are strip-shaped and equidistantly arranged along the axis of the placement hole.

[0010] To support the substrate, preferably, the positioning frame is provided with symmetrical grooves, and the support plate is slidably connected in the grooves. When the support plate is pulled outward, a first working area is formed, and when the support plate is pushed inward, a second working area is formed.

[0011] To facilitate pulling out, both support plates are further fixedly connected with handles for easy gripping.

[0012] For ease of handling, preferably, a handle for gripping is fixedly connected to the mounting plate.

[0013] In order to combine the substrate with the positioning frame, preferably, the positioning frame is provided with symmetrical slides, and the two ends of the mounting plate are provided with grooves that match the slides. The slides are covered with damping pads, and when the mounting plate slides on the positioning frame, the damping pads abut against the inner wall of the grooves.

[0014] To improve installation stability, preferably, the static friction coefficient between the damping pad and the inner wall of the groove is 0.6μ-0.8μ.

[0015] To protect the ceramic substrate, the anti-slip pad is preferably made of rubber.

[0016] For mounting the positioning frame, preferably, the positioning frame has symmetrically provided threaded holes for connecting with the printing equipment, and bolts are provided in the threaded holes.

[0017] Compared with the prior art, this utility model provides a special ceramic metallization printing fixture, which has the following beneficial effects:

[0018] 1. This special ceramic metallization printing fixture, through the setting of a mounting plate and placement holes, has several placement holes on the mounting plate, which can be circular or square to adapt to various types of ceramic substrates. The attached figure shows a circular placement hole. When the ceramic substrate is placed into the placement hole, it will directly contact the anti-slip texture on the anti-slip pad, and the elasticity of the elastic sheet will be used to squeeze the side wall of the ceramic substrate, thereby achieving the limitation of the ceramic substrate. It can adapt to ceramic substrates of different sizes of the same type, effectively improving the adaptability of the mounting plate to ceramic substrates and further improving the production and processing efficiency.

[0019] 2. This special ceramic metallization printing fixture, through the setting of support plates, when the ends of the two sets of support plates are located within the positioning frame, the bottom of the support plate will abut against the end of the upright, and the upright will provide support for the support plate. At this time, when the mounting plate is placed within the positioning frame, the bottom of the mounting plate will contact the upper surface of the support plate, so that the upper surface of the mounting plate is at the same level as the surface of the positioning frame, which facilitates the subsequent printing process and provides stable placement for the mounting plate. At this time, the bottom of the ceramic substrate will contact the support rod on the round rod, and multiple sets of support rods will support the ceramic substrate in the placement hole, thereby realizing secondary positioning of the ceramic substrate. This effectively prevents the ceramic substrate from shifting during the printing process, ensuring printing accuracy and improving the clamping stability of the ceramic substrate.

[0020] 3. This special ceramic metallization printing fixture, through the setting of round rods and support rods, releases the support plate from the positioning frame when the support plate is outside the positioning frame, allowing the positioning plate to move downward within the positioning frame. When the positioning plate moves downward, the support rods provide an upward thrust to the bottom of the ceramic substrate, causing the ceramic substrate to detach from the anti-slip pad on the elastic sheet, thus completing the unloading of the ceramic substrate. Because the elastic sheet is convex, the bottom of the unloaded ceramic substrate will contact the upper end of the elastic sheet and provide support, preventing the ceramic substrate from re-entering the placement hole. This achieves a convenient unloading process after printing on the ceramic substrate, avoiding the need for operators to unload one by one, improving unloading efficiency and further enhancing production efficiency.

[0021] 4. This special ceramic metallization printing fixture, through the setting of damping pads, will contact the damping pads on the slide when the mounting plate is placed into the positioning frame. The damping pads reduce the downward sliding distance of the mounting plate, and the friction coefficient between the damping pads and the grooves further achieves the limiting effect on the mounting plate and improves the printing accuracy.

[0022] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention effectively improves the adaptability to circular ceramic substrates of different sizes, enhances the stability of ceramic substrate placement, avoids shaking during printing, and effectively improves processing accuracy.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0030] Example:

[0031] Reference Figures 1-4A special ceramic metallization printing fixture includes a positioning frame 1 and a mounting plate 2 that is detachably installed inside the positioning frame 1. A handle 12 for hand gripping is fixedly connected to the mounting plate 2. The positioning frame 1 has symmetrically opened threaded holes 16 for connecting with printing equipment, and bolts 17 are provided in the threaded holes 16. Here, the positioning frame 1 is fixedly installed with the transport equipment on the printing equipment by bolts 17. When the positioning frame 1 is fixed, the mounting plate 2 can be put in to form a complete fixture, which is convenient for operators to assemble.

[0032] It also includes placement holes 3 arranged in a rectangular array on the mounting plate 2 for placing ceramic substrates. Each of the multiple placement holes 3 is provided with a clamping part for limiting the ceramic substrate. When the ceramic substrate is located in the placement hole 3, the surface of the ceramic substrate is on the same plane as the placement hole 3. The clamping part includes at least two sets of elastic sheets 8 provided on the inner wall of the placement hole 3. The end of the elastic sheet 8 is fixedly connected to the inner wall of the placement hole 3, and the other end of the elastic sheet 8 abuts against the inner wall of the placement hole 3. An anti-slip pad 9 is fixedly connected to the elastic sheet 8. When the ceramic substrate is located in the placement hole 3, the anti-slip pad 9 abuts against its outer wall to form a clamping area. The anti-slip pad 9 is made of rubber and has anti-slip texture. The anti-slip texture is strip-shaped and equidistantly arranged along the axial direction of the placement hole 3. A handle 12 for hand grip is fixedly connected to the mounting plate 2.

[0033] Here, the mounting plate 2 has several placement holes 3, which can be circular or square to accommodate various types of ceramic substrates. The attached diagram shows a circular placement hole 3. When the ceramic substrate is placed into the placement hole 3, it will directly contact the anti-slip texture on the anti-slip pad 9, and the elasticity of the elastic sheet 8 will be used to press against the side wall of the ceramic substrate, thereby limiting the position of the ceramic substrate. It can also accommodate ceramic substrates of different sizes of the same type, effectively improving the compatibility of the mounting plate 2 with ceramic substrates and further improving production efficiency.

[0034] Support plates 4 slide symmetrically on the positioning frame 1. Vertical rods 5 are symmetrically installed on the bottom wall of the positioning frame 1. When the two sets of support plates 4 abut against the vertical rods 5, a support part is formed to support the placement plate 2. Slide grooves 10 are symmetrically opened on the positioning frame 1, and the support plates 4 are slidably connected in the slide grooves 10. When the support plates 4 are pulled outward, a first working area is formed. When the support plates 4 are pushed inward, a second working area is formed. A handle 11 is fixedly connected to both sets of support plates 4 for easy gripping. Round rods 6 are arranged in a rectangular row at the bottom of the positioning frame 1, and the round rods 6 are coaxial with the placement hole 3. A support rod 7 is fixedly connected to the end of the round rod 6. When the ceramic substrate is located in the placement hole 3, the bottom of the ceramic substrate abuts against the support rod 7.

[0035] Here, in the first working area, when the ends of the two sets of support plates 4 are located inside the positioning frame 1, the bottom of the support plate 4 will abut against the end of the upright 5, and the upright 5 will provide support for the support plate 4. At this time, when the placement plate 2 is placed inside the positioning frame 1, the bottom of the placement plate 2 will contact the upper surface of the support plate 4, so that the upper surface of the placement plate 2 and the surface of the positioning frame 1 are at the same level, which facilitates the subsequent printing process and provides stable placement for the placement plate 2. At this time, the bottom of the ceramic substrate will contact the support rod 7 on the round rod 6, and multiple sets of support rods 7 will support the ceramic substrate in the placement hole 3, thereby realizing the secondary positioning of the ceramic substrate, effectively ensuring that the ceramic substrate will not be displaced during the printing process, ensuring the printing accuracy, and improving the clamping stability of the ceramic substrate.

[0036] Here, in the second working area, when the support plate 4 is located outside the positioning frame 1, the support for the mounting plate 2 is released, allowing the mounting plate 2 to move downward within the positioning frame 1. When the mounting plate 2 moves downward, the support rod 7 provides an upward thrust to the bottom of the ceramic substrate, causing the ceramic substrate to detach from the anti-slip pad 9 on the elastic sheet 8, thus completing the unloading of the ceramic substrate. Because the elastic sheet 8 is convex, the bottom of the unloaded ceramic substrate will contact the upper end of the elastic sheet 8 and provide support, preventing the ceramic substrate from re-entering the placement hole 3. This achieves a convenient unloading process after printing on the ceramic substrate, avoiding the need for operators to unload one by one, improving unloading efficiency and further enhancing production efficiency.

[0037] The positioning frame 1 has symmetrically arranged slide rails 13, and the two ends of the mounting plate 2 have grooves 14 that match the slide rails 13. The slide rails 13 are covered with damping pads 15. When the mounting plate 2 slides on the positioning frame 1, the damping pads 15 abut against the inner wall of the grooves 14. The static friction coefficient between the damping pads 15 and the inner wall of the grooves 14 is 0.6μ-0.8μ, preferably 0.7μ. The mounting plate 2 can be held on the positioning frame 1 without displacement without the application of external force. Here, when the mounting plate 2 is placed into the positioning frame 1, it will contact the damping pads 15 on the slide rails 13. The damping pads 15 are used to reduce the sliding distance of the mounting plate 2, and the friction coefficient between the damping pads 15 and the grooves 14 further achieves the limiting effect on the mounting plate 2 and improves the printing accuracy.

[0038] In this invention, the operator places the ceramic substrate into the corresponding placement hole 3, uses the elastic sheet 8 and anti-slip pad 9 to limit the ceramic substrate, and ensures that the surface of the ceramic substrate and the surface of the mounting plate 2 are on the same horizontal plane. Then, the operator aligns the groove 14 of the mounting plate 2 with the slide 13 on the positioning frame 1, and pushes the mounting plate 2 downward into the positioning frame 1. The damping pad 15 provides resistance when the mounting plate 2 moves until the bottom of the mounting plate 2 contacts the support plate 4, and stops pushing the mounting plate 2. In this state, the support rod 7 on the round rod 6 contacts the bottom of the ceramic substrate. After printing is completed, the operator pulls out the support plates 4 on both sides, presses the mounting plate 2 downward along the slide 13 again, and uses the support rod 7 to push the ceramic substrate out of the placement hole 3, thus completing the simultaneous discharge of the ceramic substrate.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
