Description

Technical Field

[0001] This invention relates to the field of fixtures, and in particular to a fixture capable of separating ceramics and etched leads. Background Technology

[0002] Ceramics are an industrial material, usually made from natural materials such as clay, quartz, and feldspar. They have properties such as hardness, heat resistance, wear resistance, and corrosion resistance. They can be used to protect electronic devices, providing better temperature resistance and shock resistance, and are suitable for harsh environments such as high temperature, high pressure, and high vibration.

[0003] When ceramics are used to protect electronic devices, leads (frame leads, bent frame leads, etc.) are first established for electrical signal connections. These leads need to be soldered to the ceramic one by one. However, when the entire ceramic assembly is scrapped due to problems such as incorrect lead usage or lead damage, it is necessary to re-solder and separate the ceramic and leads to ensure the subsequent use of qualified ceramics. Currently, there are very few known tooling tools for dissoldering ceramic and lead assemblies. Most of them are handmade dissoldering tools made to meet the immediate needs, which is inefficient and has a low pass rate. Therefore, we propose a tooling that can separate the ceramic and etch the leads to solve this problem. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a tooling capable of separating ceramics and etching leads. This solution involves selectively mounting a type I fixed graphite sheet, a type I sliding graphite sheet, and a type II graphite sheet above a base. To desolder the frame leads, all three types of graphite sheets are placed on the base, with the type II sheet in close contact with the support post, and the type I fixed graphite sheet in close contact with the fixed support post. The frame leads are placed between the type I sliding graphite sheet and the type II graphite sheet. To desolder the bent frame leads, only one type of fixed graphite sheet and one type of sliding graphite sheet need to be installed. The fixed graphite sheet is placed close to the pin hole, and the bent frame leads are placed between the sliding graphite sheet and the fixed support. This fills the gap in the tooling for mass desoldering lead assembly, improves the tolerance for lead damage and usage errors, and can desolder two types of ceramic components with one tooling. The mounting is convenient and efficient, highly operable, and has good ceramic positioning capability. At the same time, nickel wire is used to pass through each lead to ensure that the frame leads can be pulled out at high temperatures.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A tooling capable of separating ceramic and etched leads includes a U-shaped base with four through-holes on its surface. The through-holes are arranged in pairs on both sides of the base's short side, and each hole contains a pin. Fixed supports and contact supports are mounted on top of the base, evenly spaced on both sides of the base's long side. There are six or eight fixed supports and two contact supports. Two types of graphite sheets (Type I and Type II) are placed on top of the base. The Type I graphite sheets are further divided into fixed and sliding types. A set of rectangular through-holes runs through the surface of each Type II graphite sheet. A spring is installed between the fixed and sliding graphite sheets. Nickel wire is wound around the outside of the lead. The tooling allows for selective mounting of fixed and sliding graphite sheets on top of the base. For both movable and type II graphite sheets, to desolder the frame leads, all three types of graphite sheets—type I fixed, type I sliding, and type II—are placed on the base. The type II graphite sheet is pressed tightly against the support post, and the type I fixed graphite sheet is pressed tightly against the fixed support post. The frame leads are placed between the type I sliding graphite sheet and the type II graphite sheet. To desolder the bent frame leads, only type I fixed and type I sliding graphite sheets need to be installed. The type I fixed graphite sheet is pressed tightly against the pin hole, and the bent frame leads are placed between the type I sliding graphite sheet and the fixed support post. This fills the gap in tooling for mass desoldering lead assembly, improves the tolerance for lead damage and usage errors, and allows for the desoldering of two types of ceramic components with a single tooling. The mounting is convenient and efficient, highly operable, and provides good ceramic positioning capability. At the same time, nickel wire is used to pass through each lead to ensure that the frame leads can be pulled out at high temperatures.

[0009] To desolder the frame leads, install the type II graphite sheet above the base, then insert the lead assembly into the through hole with the ceramic facing inward and the lead facing outward, with the lead facing outward and the type II graphite sheet pressed tightly against the support. Then, place a type I fixed graphite sheet and a type I sliding graphite sheet on the base. The type I sliding graphite sheet is attached to one side of the frame lead ceramic, and the type I fixed graphite sheet abuts against the fixed support. Insert the large end of the spring clip crosswise between the type I fixed graphite sheet and the type I sliding graphite sheet with the top facing down to ensure that the product is fixed.

[0010] To desolder the bent frame lead wire, place a type of fixed graphite sheet and a type of sliding graphite sheet on the base. Then, arrange the lead wire assembly in the order of ceramic facing inward and lead wire facing outward on the fixed support. Multiple layers can be placed vertically. The type of sliding graphite sheet should abut against one side of the ceramic of the bent frame lead wire, and the type of fixed graphite sheet should abut against the abutting support. Insert the large end of the spring clip crosswise between the type of fixed graphite sheet and the type of sliding graphite sheet with the top facing down to ensure that the product is fixed. Note that the connecting part that affects the pulling down of the bent frame lead wire needs to be cut off first.

[0011] Furthermore, the bottom of one type of sliding graphite sheet is provided with a relief groove corresponding to the pin hole. When the sliding graphite sheet moves, it can avoid the pin in the pin hole through the relief groove, thereby reducing the interference to the sliding graphite sheet.

[0012] Furthermore, the through hole and the two opposing supports are staggered so that the lead wire protruding from the through hole can avoid the opposing supports and avoid affecting subsequent processing.

[0013] Furthermore, the top of the base has two slots corresponding to the type II graphite sheet and the type I fixed graphite sheet, respectively. The slots are located between the fixed support and the abutting support. When assembling the fixture, the type II graphite sheet and the type I fixed graphite sheet are inserted into the slots, so that the installation of the type II graphite sheet and the type I fixed graphite sheet is stable. This prevents the type II graphite sheet or the type I fixed graphite sheet from deflecting due to unbalanced force during the welding process, which would affect the overall fixing effect of the fixture.

[0014] Preferably, the flared portion of the slot is provided with a guide flare, and a clamping plate is rotatably connected inside the slot. The distance between the two clamping plates is the same as the thickness of the type II graphite sheet and the type I fixed graphite sheet. The clamping plates are fitted against the sidewall of the guide flare, and an elastic element is fixedly connected between the lower end of the clamping plate and the inner wall of the slot. The clamping plates assist in fixing the type II graphite sheet and the type I fixed graphite sheet. When installing the type II graphite sheet and the type I fixed graphite sheet, the clamping plates open outwards, so that the opening of the slot faces... With its wider outward extension, the Type II graphite sheet and the Type I fixed graphite sheet can quickly and accurately enter the slot, reducing installation difficulty. After the Type II graphite sheet and the Type I fixed graphite sheet are installed, the clamping plate clamps the outside of the Type II graphite sheet and the Type I fixed graphite sheet to fix them. At the same time, this can play a guiding role while preventing the guide area (tilted part) from affecting the fixing distance of the Type II graphite sheet and the Type I fixed graphite sheet.

[0015] Preferably, two stabilizing seats are installed at the bottom of the sliding graphite sheet. The stabilizing seats are arranged in a cross shape with the bottom surface of the sliding graphite sheet. The stabilizing seats are in contact with the inner wall of the base. When the sliding graphite sheet moves, the stabilizing seats slide against the inner wall of the base, so that the sliding graphite sheet always remains parallel to the long side of the base. This avoids the sliding graphite sheet from deflecting due to unbalanced force during the desoldering process, which would affect the overall fixing effect of the tooling.

[0016] Furthermore, the bottom of the sliding graphite sheet is provided with a rotating groove corresponding to the stabilizing seat. The top of the stabilizing seat is fixedly connected to a rotating shaft that is rotatably connected to the rotating groove. The inner wall of the rotating groove is fixedly connected to four fixed protrusions arranged in a circumferential array. The outer side of the rotating shaft is provided with symmetrically distributed elastic protrusions, which are distributed within the intervals of the fixed protrusions. Through the cooperation of the elastic protrusions and the fixed protrusions, the elastic protrusions are clamped by the fixed protrusions, thereby locking the rotating shaft and the stabilizing seat. In use, the stabilizing seat is set perpendicular to the bottom edge of the sliding graphite sheet, making the sliding graphite sheet more stable. When disassembling and storing, the stabilizing seat is rotated to be parallel to the bottom edge of the sliding graphite sheet for easy stacking and storage.

[0017] Furthermore, the outer surfaces of both the fixed bump and the elastic bump are arc-shaped, and the outer arc surfaces of the fixed bump and the elastic bump fit together.

[0018] Preferably, the spring is V-shaped, with the two sides of the V-shaped opening tapering inwards. A rotating wheel is rotatably connected to the outer wall of the spring, and an outer plate is fixedly connected to the outer side of the rotating wheel. A shell covering the outer side of the rotating wheel is fixedly connected to the inner side of the spring. By setting a movable outer plate on the outer side of the spring, the outer plate adjusts its posture according to the angle between the spring and the type of fixed graphite sheet and the type of sliding graphite sheet, so that the surface of the outer plate is always in contact with the surfaces of the type of fixed graphite sheet and the type of sliding graphite sheet. This increases the contact area between the spring and the type of fixed graphite sheet and the type of sliding graphite sheet, making the installation of the spring more stable and preventing the spring from slipping off between the type of fixed graphite sheet and the type of sliding graphite sheet.

[0019] Furthermore, the surface of the outer plate is textured with friction patterns to further enhance the stability of the spring clip installation.

[0020] 3. Beneficial effects

[0021] Compared with the prior art, the advantages of this invention are:

[0022] 1. This solution involves selecting and mounting three types of graphite sheets—Type I fixed graphite sheets, Type I sliding graphite sheets, and Type II graphite sheets—above the base. To desolder the frame lead wire, all three types of graphite sheets are placed on the base, with the Type II sheets flush against the support pillar and the Type I fixed graphite sheets flush against the fixed support pillar. The frame lead wire is placed between the Type I sliding graphite sheets and the Type II graphite sheets. To desolder the bent frame lead wire, only Type I sheets need to be installed. The system consists of a fixed graphite sheet and a sliding graphite sheet. The fixed graphite sheet is placed close to the pin hole, and the bent frame lead wire is placed between the sliding graphite sheet and the fixed support. This fills the gap in the tooling for batch unsoldering lead wire assemblies, improves the tolerance for lead wire damage and usage errors, and allows for the unsoldering of two types of ceramic components with one tooling. The assembly is convenient and efficient, highly operable, and has good ceramic positioning capability. At the same time, nickel wire is used to pass through each lead wire to ensure that the frame lead wire can be pulled out at high temperatures.

[0023] 2. The clamping plate assists in fixing the Type II graphite sheet and the Type I fixed graphite sheet. When installing the Type II graphite sheet and the Type I fixed graphite sheet, the clamping plate opens outward, making the opening of the slot extend and widen outward. The Type II graphite sheet and the Type I fixed graphite sheet can quickly and accurately enter the slot, reducing the installation difficulty. After the Type II graphite sheet and the Type I fixed graphite sheet are installed, the clamping plate clamps on the outside of the Type II graphite sheet and the Type I fixed graphite sheet to fix them. At the same time, this can play a guiding role while preventing the guide area (tilted part) from affecting the fixing distance of the Type II graphite sheet and the Type I fixed graphite sheet.

[0024] 3. Through the cooperation of the elastic protrusion and the fixed protrusion, the elastic protrusion is clamped by the fixed protrusion, which locks the rotating shaft and the stabilizing seat. When in use, the stabilizing seat is set perpendicular to the bottom edge of the sliding graphite sheet, making the sliding graphite sheet more stable. When disassembling and storing, rotate the stabilizing seat to be parallel to the bottom edge of the sliding graphite sheet for easy stacking and storage.

[0025] 4. By setting a movable outer plate on the outside of the spring, the outer plate adjusts its posture according to the angle between the spring and the type of fixed graphite sheet and the type of sliding graphite sheet, so that the surface of the outer plate is always in contact with the surfaces of the type of fixed graphite sheet and the type of sliding graphite sheet. This increases the contact area between the spring and the type of fixed graphite sheet and the type of sliding graphite sheet, making the installation of the spring more stable and preventing the spring from slipping off between the type of fixed graphite sheet and the type of sliding graphite sheet.

[0040] Example:

[0041] Please see Figure 1-4 A tooling capable of separating ceramics and etched leads includes a U-shaped base 1. The surface of the base 1 has four through-holes 2, arranged in pairs on both sides of the short side of the base 1. Pins are installed in the holes 2. Above the base 1 are fixed supports 3 and abutment supports 4, evenly spaced on both sides of the long side of the base 1. There are six or eight fixed supports 3 and two abutment supports 4. A graphite sheet 5 and two... The graphite sheet 6 is of type I and type II. Type I graphite sheet 5 is divided into type I fixed graphite sheet 51 and type I sliding graphite sheet 52. Type II graphite sheet 6 has a set of rectangular through holes 61 extending from front to back on its surface. A spring 7 is installed between type I fixed graphite sheet 51 and type I sliding graphite sheet 52. Nickel wire is wound around the outside of the lead wire. To unsolder the frame lead wire, the type II graphite sheet 6 is installed above the base 1, and then the lead wire assembly is inserted into the through holes 61 with the ceramic facing inwards and the lead wire facing outwards. The second type of graphite sheet 6 is tightly attached to the support post 4. Then, a first type of fixed graphite sheet 51 and a first type of sliding graphite sheet 52 are placed on the base 1. The first type of sliding graphite sheet 52 is attached to one side of the ceramic lead wire in the frame, and the first type of fixed graphite sheet 51 abuts against the fixed support post 3. The large end of the spring piece 7 is inserted crosswise between the first type of fixed graphite sheet 51 and the first type of sliding graphite sheet 52 with the large end facing down to ensure that the product is fixed. If it is necessary to desolder and bend the frame lead wire, place the first type of fixed graphite sheet 51 and the first type of sliding graphite sheet 52 on the base 1, and then place the lead wire... The components are arranged in order, with the ceramic facing inward and the lead wire facing outward, and are fitted onto the fixed support 3. Multiple layers can be placed vertically. A type of sliding graphite sheet 52 abuts against one side of the bent frame lead wire ceramic, and a type of fixed graphite sheet 51 abuts against the abutting support 4. The large end of the spring piece 7 is inserted crosswise between the type of fixed graphite sheet 51 and the type of sliding graphite sheet 52 with the top facing down to ensure that the product is fixed. Note that the connecting part that affects the pulling down of the bent frame lead wire needs to be cut off first. At the same time, a nickel wire is used to pass through each lead wire to ensure that the frame lead wire can be pulled out at high temperature.

[0042] The bottom of the sliding graphite sheet 52 is provided with a relief groove 53 corresponding to the pin hole 2. When the sliding graphite sheet 52 moves, it can avoid the pin in the pin hole 2 through the relief groove 53, reducing the interference to the sliding graphite sheet 52. The through hole 61 is offset from the two abutting support pillars 4, so that the lead wire protruding from the through hole 61 can avoid the abutting support pillars 4, avoiding affecting subsequent processing.

[0043] Please see Figure 1-6 The base 1 has two slots 8 on its top, corresponding to the type II graphite sheet 6 and the type I fixed graphite sheet 51 respectively. The slots 8 are located between the fixed support column 3 and the abutting support column 4. When assembling the fixture, the type II graphite sheet 6 and the type I fixed graphite sheet 51 are inserted into the slots 8, making the installation of the type II graphite sheet 6 and the type I fixed graphite sheet 51 stable and preventing the type II graphite sheet 6 or the type I fixed graphite sheet 51 from deflecting due to unbalanced force during the welding process, which would affect the overall fixing effect of the fixture. The slots 8 have guide flares 81 at their flared ends. The slots 8 are rotatably connected to clamping plates 82. The distance between the two clamping plates 82 is the same as the thickness of the type II graphite sheet 6 and the type I fixed graphite sheet 51. The clamping plates 82 fit against the side wall of the guide flares 81. The lower end of the clamping plates 82 and the slots 8 are connected to the side wall of the guide flares 81. An elastic element 83 is fixedly connected between the inner walls of the two materials. The clamping plate 82 assists in fixing the type II graphite sheet 6 and the type I fixed graphite sheet 51. When installing the type II graphite sheet 6 and the type I fixed graphite sheet 51, the clamping plate 82 opens outward, making the opening of the slot 8 extend and widen outward. The type II graphite sheet 6 and the type I fixed graphite sheet 51 can quickly and accurately enter the slot 8, reducing the installation difficulty. After the type II graphite sheet 6 and the type I fixed graphite sheet 51 are installed, the clamping plate 82 clamps the outside of the type II graphite sheet 6 and the type I fixed graphite sheet 51 to fix them. At the same time, this can play a guiding role while preventing the guiding area (inclined part) from affecting the fixing distance of the type II graphite sheet 6 and the type I fixed graphite sheet 51.

[0044] Two stabilizing seats 54 are installed at the bottom of a sliding graphite sheet 52. The stabilizing seats 54 are arranged in a cross shape with the bottom surface of the sliding graphite sheet 52. The stabilizing seats 54 are in contact with the inner wall of the base 1. When the sliding graphite sheet 52 moves, the stabilizing seats 54 slide against the inner wall of the base 1, so that the sliding graphite sheet 52 always remains parallel to the long side of the base 1. This prevents the sliding graphite sheet 52 from deflecting due to unbalanced force during the desoldering process, which would affect the overall fixing effect of the fixture. The bottom of the sliding graphite sheet 52 has a rotating groove 55 corresponding to the stabilizing seat 54. The top of the stabilizing seat 54 is fixedly connected to a rotating shaft 56 that is rotatably connected to the rotating groove 55. The inner wall of the rotating groove 55 is fixedly connected to four circular... The fixed protrusions 57 are arranged in a circumferential array, and the outer side of the rotating shaft 56 is provided with symmetrically distributed elastic protrusions 58. The elastic protrusions 58 are distributed within the intervals of the fixed protrusions 57. The outer surfaces of both the fixed protrusions 57 and the elastic protrusions 58 are arc-shaped, and the outer arc surfaces of the fixed protrusions 57 and the elastic protrusions 58 fit together. Through the cooperation of the elastic protrusions 58 and the fixed protrusions 57, the elastic protrusions 58 are clamped by the fixed protrusions 57, thereby locking the rotating shaft 56 and the stabilizing seat 54. In use, the stabilizing seat 54 is set perpendicular to the bottom edge of the sliding graphite sheet 52, making the sliding graphite sheet 52 more stable. When disassembling and storing, the stabilizing seat 54 is rotated until it is parallel to the bottom edge of the sliding graphite sheet 52, which facilitates stacking and storage.

[0045] Please see Figure 1-10 The spring piece 7 is V-shaped, with the two sides of the V-shaped opening tapering inwards. A rotating wheel 71 is rotatably connected to the outer wall of the spring piece 7. An outer plate 72 is fixedly connected to the outer side of the rotating wheel 71. A shell covering the outer side of the rotating wheel 71 is fixedly connected to the inner side of the spring piece 7. Friction textures are provided on the surface of the outer plate 72 to further enhance the stability of the spring piece 7 during installation. By providing a movable outer plate 72 on the outer side of the spring piece 7, the outer plate 72 will adjust its posture according to the angle between the spring piece 7 and the type of fixed graphite sheet 51 and the type of sliding graphite sheet 52, so that the surface of the outer plate 72 is always in contact with the surfaces of the type of fixed graphite sheet 51 and the type of sliding graphite sheet 52. This increases the contact area between the spring piece 7 and the type of fixed graphite sheet 51 and the type of sliding graphite sheet 52, making the installation of the spring piece 7 more stable and preventing the spring piece 7 from slipping off between the type of fixed graphite sheet 51 and the type of sliding graphite sheet 52.
