Description

Technical Field

[0001] This utility model relates to the technical field of silicon nitride substrate adhesive removal clamping fixtures, and in particular to a vertical adhesive removal clamping fixture for silicon nitride substrates. Background Technology

[0002] Silicon nitride substrates are ceramic circuit boards or packaging carriers made from high-purity silicon nitride powder through ceramic preparation processes (such as tape casting, dry pressing, hot pressing sintering, gas pressure sintering, etc.). They are used to carry and connect electronic components (such as chips and power devices) and provide functions such as electrical insulation, thermal diffusion, and mechanical support.

[0003] However, existing silicon nitride substrates cannot be vertically stably arranged or the vertical spacing is not adjustable when vertically dispensing adhesive, resulting in easy contact between substrates, poor air venting, and uneven adhesive dispensing. They cannot be adapted to vertical adhesive dispensing clamping of different types of silicon nitride substrates, reducing the practicality of the device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vertical adhesive application clamping fixture for silicon nitride substrates.

[0005] The purpose of this utility model is achieved as follows: A vertical adhesive removal clamping fixture for silicon nitride substrates includes: a base plate, on which an elastic clamping mechanism is provided, the elastic clamping mechanism including a fixed side plate, the fixed side plate being fixedly connected to the upper end of the base plate, the fixed side plate being provided in multiple sets, the two sets of fixed side plates corresponding one to one, a placement cavity being formed between the two sets of fixed side plates, and a clamping plate being provided in the fixed side plate, the clamping plate being slidably connected to the fixed side plate through an elastic clamping assembly.

[0006] Preferably, the elastic clamping assembly includes a fixed post and a sliding post. The fixed post is fixedly disposed inside the fixed side plate, and the sliding post is slidably disposed inside the fixed post. The end of the sliding post away from the fixed post is fixedly connected to the outer wall of the clamping plate. A fixed rod is inserted inside the sliding post, and a spring is wound around the surface of the fixed rod. One end of the spring is connected to the end of the sliding post inserted inside the fixed post.

[0007] Preferably, the other end of the spring is connected to a damper, which is installed inside the fixed column.

[0008] Preferably, a slider is fixedly connected to the side wall of the sliding column, and the slider is slidably disposed inside the sliding groove, which is opened inside the fixed column.

[0009] Preferably, the base plate has an internal mounting groove, and mounting bolts are installed inside the mounting groove and mounted on the mounting surface.

[0010] Preferably, an auxiliary fixing mechanism is provided on the fixed side plate. The auxiliary fixing mechanism includes a pressure plate, which is slidably disposed inside the fixed side plate. An adjusting screw is installed inside the pressure plate and is installed inside the fixed side plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes the cooperation of a fixed side plate, a placement cavity, an elastic clamping assembly, a clamping plate, a fixed column, a sliding column, a fixed rod, a spring, and a damper to pull the clamping plate to both sides, vertically placing the silicon nitride substrate inside the placement cavity. When the clamping plate is released, the sliding column compresses the spring, putting the spring into a compressed, stored state. After the silicon nitride substrate is placed in the placement cavity, the clamping plate is slowly released, and the spring force automatically moves the clamping plate closer to the silicon nitride substrate until the clamping plate elastically clamps the silicon nitride substrate, achieving adaptive clamping. It can elastically clamp silicon nitride substrates of different sizes. This vertical adhesive removal clamping fixture for silicon nitride substrates uses elastic clamping to vertically and adaptively clamp the silicon nitride substrate, matching the fixing of multiple types of silicon nitride substrates without damaging the substrate, thus improving the practicality and stability of the device.

[0012] 2. This utility model, through the cooperation of the pressure plate and the adjusting screw, after the side of the silicon nitride substrate is limited, the adjusting screw can be rotated to adjust the position of the pressure plate inside the fixed side plate, so that the bottom surface of the pressure plate slightly presses against the upper end of the silicon nitride substrate. This can achieve the effect of auxiliary fixation with the elastic clamping mechanism without compressing the silicon nitride substrate. The vertical glue discharge clamping fixture for silicon nitride substrate can use the pressure plate set on the top surface to provide top auxiliary fixation for the silicon nitride substrate, which improves stability without compressing the silicon nitride substrate, thus improving the practicality and stability of the device.

Detailed Implementation

[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] like Figure 1-4 The present invention provides one embodiment as shown: A vertical adhesive removal clamping fixture for silicon nitride substrates. The base plate 111 used in this application is a product that can be directly purchased on the market. Its principle and connection method are existing technologies well known to those skilled in the art. Includes: a base plate 111, on which an elastic clamping mechanism 2 is provided, the elastic clamping mechanism 2 includes a fixed side plate 211, the fixed side plate 211 is fixedly connected to the upper end of the base plate 111, multiple sets of fixed side plates 211 are provided, two sets of fixed side plates 211 correspond one to one, a placement cavity 213 is formed between the two sets of fixed side plates 211, a clamping plate 215 is provided in the fixed side plate 211, and the clamping plate 215 is slidably connected to the fixed side plate 211 through an elastic clamping assembly 214; Using the vertical adhesive removal clamping fixture for silicon nitride substrates, pull the clamping plates 215 to move to both sides, and place the silicon nitride substrate vertically inside the placement cavity 213. At this time, the elastic element inside the elastic clamping assembly 214 is in a compressed and stored state. After the silicon nitride substrate is positioned, slowly release the clamping plates 215. The two sets of clamping plates 215 can be used to limit the silicon nitride substrate on both sides, and can elastically clamp silicon nitride substrates of different sizes.

[0021] The elastic clamping assembly 214 includes a fixed post 216 and a sliding post 217. The fixed post 216 is fixedly disposed inside the fixed side plate 211, and the sliding post 217 is slidably disposed inside the fixed post 216. One end of the sliding post 217 away from the fixed post 216 is fixedly connected to the outer wall of the clamping plate 215. A fixed rod 218 is inserted inside the sliding post 217, and a spring 219 is wound around the surface of the fixed rod 218. One end of the spring 219 is connected to the end of the sliding post 217 inserted inside the fixed post 216. When the elastic clamping assembly 214 drives the clamping plate 215 to elastically clamp, and pulls the clamping plate 215 to move away from the center of the placement cavity 213, the sliding column 217 squeezes the spring 219, so that the spring 219 is in a compressed and stored state. After the silicon nitride substrate is placed in the placement cavity 213, the clamping plate 215 is slowly released. The elastic force of the spring 219 can automatically drive the clamping plate 215 to move closer to the silicon nitride substrate until the clamping plate 215 elastically clamps the silicon nitride substrate, which can achieve adaptive clamping.

[0022] The other end of the spring 219 is connected to the damper 220, which is installed inside the fixed post 216; The damper 220 can decompose the potential energy generated by the spring 219 and prevent the spring 219 from vibrating repeatedly.

[0023] A slider 221 is fixedly connected to the side wall of the sliding column 217. The slider 221 is slidably disposed inside the slide groove 222, which is opened inside the fixed column 216. When the sliding column 217 moves, the slider 221 slides synchronously inside the groove 222, thereby limiting the sliding column 217 and making its sliding more stable.

[0024] The base plate 111 has an internal mounting groove 224, and a mounting bolt 223 is installed inside the mounting groove 224 and is mounted on the mounting surface. The base plate 111 is assembled onto the mounting surface using mounting bolts 223, which is simple to operate and ensures a secure installation.

[0025] An auxiliary fixing mechanism 3 is provided on the fixed side plate 211. The auxiliary fixing mechanism 3 includes a pressure plate 311, which is slidably disposed inside the fixed side plate 211. An adjusting screw 312 is installed inside the pressure plate 311. Using this silicon nitride substrate vertical adhesive removal clamping fixture, after the side limit of the silicon nitride substrate is reached, the adjusting screw 312 can be rotated to adjust the position of the pressure plate 311 inside the fixed side plate 211, so that the bottom surface of the pressure plate 311 slightly presses against the upper end of the silicon nitride substrate. This can achieve the effect of auxiliary fixation in conjunction with the elastic clamping mechanism 2, without compressing the silicon nitride substrate.

[0026] Working principle: Using this silicon nitride substrate vertical adhesive removal clamping fixture, pull the clamping plate 215 to move to both sides, vertically placing the silicon nitride substrate inside the placement cavity 213. Release the clamping plate 215, at which point the sliding column 217 compresses the spring 219, putting the spring 219 into a compressed and stored state. After placing the silicon nitride substrate in the placement cavity 213, slowly release the clamping plate 215. The elastic force of the spring 219 can automatically drive the clamping plate 215 closer to the silicon nitride substrate until the clamping plate 215 elastically clamps the silicon nitride substrate, achieving adaptive clamping and elastically clamping silicon nitride substrates of different sizes.

[0027] Using this silicon nitride substrate vertical adhesive removal clamping fixture, after the side limit of the silicon nitride substrate is reached, the adjusting screw 312 can be rotated to adjust the position of the pressure plate 311 inside the fixed side plate 211, so that the bottom surface of the pressure plate 311 slightly presses against the upper end of the silicon nitride substrate. This can achieve the effect of auxiliary fixation in conjunction with the elastic clamping mechanism 2, without compressing the silicon nitride substrate. The operation is now complete.

[0028] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
