Description

Technical Field

[0001] This utility model relates to the field of brazing production and manufacturing technology, and in particular to a mold for processing the end face of a ceramic packaging shell. Background Technology

[0002] Brazing is a process that involves heating and filling a workpiece with a low-temperature metal material (below its melting point) to form a joint. During brazing, the base metal does not melt; instead, molten filler metal is drawn into the joint through capillary action, thus achieving the connection. Therefore, after brazing, the filler metal spreads across the entire surface of the metal frame. To avoid affecting subsequent capping and to improve the flatness of the seal, end-face treatment is required. The end-face treatment process typically includes grinding, inspection, and cleaning. The detailed functions of each step are as follows:

[0003] Grinding: The end face of the brazed ceramic encapsulation shell, including the sealing surface, is treated. The end face is placed face down on the gauze paper, and the shell is repeatedly ground by hand to remove excess silver and copper solder from the end face.

[0004] Inspection: The sealing and polishing status of each polished ceramic package shell is checked one by one to ensure there is no solder residue or other polishing defects.

[0005] Cleaning: The polished ceramic encapsulation shell is blown away with an air gun to remove polishing dust.

[0006] In summary, the sequence and function of these work segments together ensure the quality and reliability of the end-face processing.

[0007] In the existing technology, when processing the cross-section of specific ceramic packaging shells, such as small-sized shells and shells with bent leads, protection is often not provided, and manual grinding is carried out directly by hand. On the one hand, this will cause the grinding edge to collapse, increasing the product defect rate, and only one can be ground at a time, which is slow. On the other hand, the pressure on the lead will cause the lead to deform, resulting in the failure of the bent lead.

[0008] Therefore, there is an urgent need for a mold for processing the end face of ceramic packaging shells to solve the above technical problems. Utility Model Content

[0009] The purpose of this utility model is to provide a mold for the end face processing of ceramic packaging shells. This mold can protect the cross-section of ceramic packaging shells of specific models during grinding, reduce direct manual contact with ceramic packaging shells, improve the end face processing yield, and at the same time avoid critical positions of leads, increase the stress area, and significantly reduce the difficulty of manual operation.

[0010] To achieve the aforementioned objectives, the present invention employs the following technical solution: a mold for end-face processing of ceramic encapsulation shells, comprising a main body plate. Multiple limiting grooves are provided on the upper surface of the main body plate, and multiple limiting bosses are provided within the limiting grooves. The top surface of the limiting bosses is flush with the upper surface of the main body plate or located inside the limiting grooves. The shell to be polished is embedded into the limiting groove of the mold, with the sealing surface facing upwards. The limiting bosses within the limiting grooves directly contact the ceramic portion of the shell to limit its position, while simultaneously avoiding the lead wire location, thus protecting the brazing lead wires and preventing deformation during polishing. After the shell is fixed, the mold is inverted onto sandpaper, and the back of the acrylic mold is manually pressed down for repeated polishing. This allows for simultaneous end-face processing of multiple ceramic encapsulation shells, thereby improving production efficiency. After polishing, the ceramic encapsulation shells are removed and replaced, and the process is repeated cyclically to achieve efficient and stable end-face processing.

[0011] Furthermore, the limiting boss is integrally set on the bottom wall of the limiting groove. The position of the limiting boss cannot be changed. It is designed and processed according to the cross-section of the ceramic encapsulation shell of a specific model. The main plate is made of acrylic material. Acrylic material has high transparency, good weather resistance, is easy to process, has a variety of varieties, and is convenient to use.

[0012] Furthermore, the bottom wall of the limiting groove is evenly provided with multiple insertion holes, and the lower end of the limiting boss is provided with a plug rod that matches the insertion hole. By providing multiple insertion holes, the limiting boss can be inserted into different insertion holes through the plug rod. This can change the placement position of the limiting boss, thereby making it applicable to different types and shapes of ceramic packaging shells, reducing the types of molds, and making it easy to operate and highly applicable.

[0013] Furthermore, the bottom wall of the limiting groove is provided with multiple parallel guide grooves, and an adjusting rod is rotatably inserted into the side wall of the main body plate. One end of the adjusting rod is located outside the main body plate, and the other end extends into the guide groove and is rotatably connected to the side wall of the guide groove. The limiting boss is threadedly connected to the adjusting rod. Rotating the adjusting rod can drive the corresponding limiting boss to move along the length direction of the guide groove. The outer surface of the adjusting rod located in the guide groove is provided with external threads, and the lower end of the limiting boss is provided with a threaded hole. The adjusting rod with external threads passes through the threaded hole. When the adjusting rod is rotated, the limiting boss can be driven to move along the guide groove, thereby adjusting the position of the limiting boss. The adjustment accuracy is higher, the applicability is stronger, and it can be used for more end face shapes and structures of ceramic packaging shells.

[0014] Furthermore, a knob is provided at the end of the adjustment rod located outside the main body plate. The outer surface of the knob is covered with a layer of soft material. The knob facilitates the rotation of the adjustment rod, and the soft material helps to protect the user's hands.

[0015] Furthermore, the limiting groove is quadrilateral, and each of the four corners of the limiting groove is chamfered, which is required for machining, thus facilitating the cutting process.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This mold can be made of acrylic material, which is easy to process, has a simple structure, a long service life, and wide applicability;

[0018] 2. Special molds are designed for small-sized housings and housings with bent leads, which can avoid critical positions of the leads, protect the leads, increase the stress area, and significantly reduce the difficulty of manual operation.

[0019] 3. Design a multi-row mold according to the size of the ceramic packaging shell, that is, multiple limiting grooves, each limiting groove is used to install one ceramic packaging shell end face, and multiple ceramic packaging shells are polished at one time, which helps to improve production efficiency;

[0020] 4. By using a mold for end face processing, the ceramic encapsulation shell is placed upside down on sandpaper during use, and the back of the mold is held down manually to reduce direct manual contact with the ceramic encapsulation shell and improve the yield of end face processing.

[0021] 5. The limiting boss is set to be movable. By changing the position of the limiting boss, it can be applied to the end face of ceramic packaging shells of different types and shapes, thereby reducing the types of molds, and is easy to operate and highly applicable.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Of course, the specific embodiments described herein are only for explaining this utility model and are not intended to limit it.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a mold for processing the end face of a ceramic encapsulation shell, including a main body plate 1. Multiple limiting grooves 2 are provided on the upper surface of the main body plate 1, and multiple limiting bosses 3 are provided within the limiting grooves 2. The top surface of the limiting bosses 3 is flush with the upper surface of the main body plate 1 or located inside the limiting grooves 2. The shell to be polished is embedded into the limiting groove of the mold, with the sealing surface facing upwards. The limiting bosses 3 within the limiting grooves 2 directly contact the ceramic part of the shell to limit its position, while also avoiding the lead wire location, thus protecting the brazing lead wire and preventing deformation during polishing. After the shell is fixed, the mold is inverted onto sandpaper, and the back of the acrylic mold is manually pressed and repeatedly polished. Multiple ceramic encapsulation shells are simultaneously subjected to end-face processing to improve production efficiency. After grinding, the ceramic encapsulation shells are removed and replaced, and the operation is repeated to achieve efficient and stable end-face processing. The limiting boss 3 is integrally set on the bottom wall of the limiting groove 2 and is integrally processed. The position of the limiting boss 3 cannot be changed. It is designed and processed according to the cross-section of the specific model of ceramic encapsulation shell. The main plate 1 is made of acrylic material. Acrylic material has high transparency, good weather resistance, is easy to process, has a variety of types, and is convenient to use. The limiting groove 2 is quadrilateral, and chamfers are set at the four corners of the limiting groove 2. The chamfers are required for machining, which facilitates the cutting tool.

[0031] Example 2

[0032] like Figure 3 As shown, the main difference from Embodiment 1 is that the limiting boss 3 is designed to be detachable. That is, multiple insertion holes 4 are evenly arranged on the bottom wall of the limiting groove 2, and the lower end of the limiting boss 3 is provided with a plug rod that matches the insertion hole 4. By providing multiple insertion holes 4, the limiting boss 3 can be inserted into different insertion holes 4 through the plug rod. This allows the placement position of the limiting boss 3 to be changed, thereby making it suitable for different types and shapes of ceramic encapsulation shells, reducing the types of molds, and making it easy to operate and highly applicable.

[0033] Example 3

[0034] like Figure 4As shown, the main difference from Embodiment 1 is that the limiting boss 3 is movable, the bottom wall of the limiting groove 2 is provided with multiple parallel guide grooves 5, and an adjusting rod 6 is rotatably inserted into the side wall of the main body plate 1. One end of the adjusting rod 6 is located outside the main body plate 1, and the other end extends into the guide groove 5 and is rotatably connected to the side wall of the guide groove 5. The limiting boss 3 is threadedly connected to the adjusting rod 6. Rotating the adjusting rod 6 can drive the corresponding limiting boss 3 to move along the length direction of the guide groove 5. The outer surface of the adjusting rod 6 located in the guide groove 5 is provided with external threads. The lower end of the 3 is provided with a threaded hole, and the adjusting rod 6 with external thread passes through the threaded hole. When the adjusting rod 6 is rotated, the limiting boss 3 can be driven to move along the guide groove 5, thereby adjusting the position of the limiting boss 3. The adjustment accuracy is higher and the applicability is stronger, which can be used for more end face shapes and structures of ceramic encapsulation shells. The end of the adjusting rod 6 located outside the main body plate 1 is provided with a knob 7. The outer surface of the knob 7 is covered with a layer of soft material. The setting of the knob 7 makes it easy to rotate the adjusting rod 6, and the soft material helps to protect the user's hands.

[0035] The working principle of this utility model is as follows: The shell to be polished is embedded in the limiting groove 2 of the mold with the sealing surface facing upward. The limiting boss 3 in the limiting groove 2 directly contacts the ceramic part of the shell to limit the shell. At the same time, it can avoid the lead wire position and protect the brazing lead wire to avoid deformation during polishing. After the shell is fixed, the mold is inverted on sandpaper, and the back of the mold is manually held and polished repeatedly. This allows for the simultaneous end-face treatment of multiple ceramic encapsulated shells, thereby improving production efficiency. After polishing, the ceramic encapsulated shell is removed and replaced. This cycle is repeated to achieve efficient and stable end-face processing.

[0036] The advantages of this mold are:

[0037] Example 1 is a mold made of acrylic material, which has a simple structure, is easy to process, has a long service life, and is widely applicable. The molds in Example 2 and Example 3 are not limited by material. Special molds are designed for small-sized shells and bent lead wire shells to avoid critical positions of the lead wires, protect the lead wires, and increase the force-bearing area, significantly reducing the difficulty of manual operation.

[0038] The multi-row mold is designed according to the size of the ceramic encapsulation shell, that is, multiple limiting grooves 2. Each limiting groove 2 is used to install one ceramic encapsulation shell end face. Multiple ceramic encapsulation shells are polished at one time, which helps to improve production efficiency. When using the mold for end face processing, the ceramic encapsulation shell is upside down on the sandpaper and the back of the mold is held manually, which reduces direct manual contact with the ceramic encapsulation shell and improves the end face processing yield.

[0039] The limiting boss 3 is designed to be movable. By changing the position of the limiting boss 3, it can be applied to the end face of ceramic packaging shells of different types and shapes, thereby reducing the types of molds and making it easy to operate and highly applicable.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
