Description

Technical Field

[0001] This invention relates to the field of electronic component processing technology, and in particular to an adjustable positioning assembly device for ceramic packaging shells. Background Technology

[0002] The packaging shell of a semiconductor chip is a major component of the integrated circuit. It not only provides mechanical protection for the chip and facilitates the external connection of the chip electrodes, but also plays a fundamental role in ensuring the correct implementation of various functional parameters of the chip, the environmental conditions required for circuit use, and the manifestation of circuit characteristics.

[0003] Semiconductor chip packaging includes metal packaging, plastic packaging, and ceramic packaging. Ceramic packaging is extremely stable in terms of thermal, electrical, and mechanical properties, providing high hermeticity protection for the chip and giving it high operational reliability. Therefore, ceramic packaging is widely used in the field of semiconductor chip packaging.

[0004] The encapsulation shell sintering mainly involves sealing the metal ring frame, lead wire, and glass insulator. First, the glass insulator is fitted onto the outside of the lead wire. Then, the glass insulator is fitted into the first mounting hole on the surface of the metal ring frame to form a semi-finished product. The semi-finished product is then placed horizontally into a sintering mold, and the sintering mold is sent into a sintering furnace for sintering at high temperature. The sintering mold is generally made of graphite, which does not wet the glass insulator or adhere to the metal ring frame, making it a relatively ideal glass-metal sealing mold.

[0005] Patent application number CN201610969273.6 discloses a method for sintering microwave metal packaging shells using a graphite mold, relating to the field of metal packaging shells. The graphite mold is an integral structure with positioning grooves and recesses for positioning leads. Using this integral graphite mold to pre-position the chassis and leads ensures the dimensional accuracy of the leads after sintering the microwave metal packaging shell, while also improving the production efficiency of microwave metal packaging shell sintering.

[0006] However, existing graphite sintering molds have a simple structure and limited functions, which cannot meet the processing requirements of existing ceramic packaging shells. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable positioning assembly device for ceramic encapsulation shells.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An adjustable positioning assembly device for a ceramic encapsulation shell includes a base plate. Support rods are fixedly installed at each of the four bottom corners of the base plate, and a movable cavity is formed inside the base plate. A central block is fixedly installed at the top. Mounting holes communicating with the movable cavities are formed around the central block at the top of the base plate. A lead screw guide sleeve is rotatably installed in any one of the mounting holes. One end of the lead screw guide sleeve is threaded with a lead screw, and the other end is fixedly fitted with a first conical tooth. A connecting rod is fixedly installed on any one of the lead screws, and a fixing block is fixedly installed at the top of any one of the connecting rods. Each fixed block has multiple pin slots evenly spaced on one side near the center block. The top of the center block has a ceramic encapsulation shell bottom shell. Multiple ceramic encapsulation shell pins that match the pin slots are fixedly installed around the bottom shell of the ceramic encapsulation shell. A rotating shaft is rotatably installed on the bottom inner wall of the movable cavity. A first worm gear is fixedly sleeved on the rotating shaft and a second bevel tooth is fixedly sleeved at the top. A first worm gear that meshes with the first worm gear is rotatably installed on one side of the base plate. Each of the first bevel teeth meshes with the second bevel tooth.

[0010] Preferably, the central block has an installation cavity and four through holes communicating with the installation cavity on all four sides. A crossbar is movably installed in each of the four through holes. A rack is fixedly installed at one end of each of the four crossbars, and an extrusion plate adapted to the bottom shell of the ceramic encapsulation shell is fixedly installed at the other end. A second worm gear and a second worm are rotatably installed on the inner walls of the installation cavity. A gear is fixedly sleeved on the outer side of any second worm gear and meshes with the corresponding second worm. Any gear meshes with the corresponding rack. A fourth bevel tooth is fixedly sleeved on one end of each second worm. A motor is fixedly installed on the top inner wall of the installation cavity. A third bevel tooth is fixedly sleeved on the output shaft of the motor, and any fourth bevel tooth meshes with the third bevel tooth.

[0011] Preferably, a crank handle is fixedly sleeved at one end of the first worm gear.

[0012] Preferably, a first sliding groove is provided on the bottom inner wall of any mounting hole, and a first slider that is fixedly connected to the corresponding lead screw is slidably installed in the first sliding groove.

[0013] Preferably, a second spring is fitted onto each crossbar, with one end of the second spring fixed to the corresponding crossbar and the other end fixed to the inner wall of the corresponding through hole.

[0014] Preferably, a torsion spring is fitted onto each lead screw guide sleeve, with one end of the torsion spring fixed to the corresponding lead screw guide sleeve and the other end fixed to the inner wall of the corresponding mounting hole.

[0015] Preferably, the top of the central block has two mounting slots, and each side of the two mounting slots has a second sliding groove. A second slider is slidably installed in each of the second sliding grooves. The same first conductive sheet is fixedly installed between the two second sliders on the same side. A movable rod is fixedly installed on the top of each of the two first conductive sheets. A second conductive sheet is fixedly installed on the bottom inner wall of each of the two mounting slots. The first conductive sheet and the second conductive sheet are both electrically connected to the motor.

[0016] Preferably, a first spring is fixedly installed between each of the second sliders and the bottom inner wall of the corresponding second slide groove.

[0017] In this invention, an adjustable positioning and assembly device for ceramic packaging shells first secures the bottom shell of the ceramic packaging shell onto the center block. Based on the specific length of the ceramic packaging shell pins, the distance between the four fixed blocks and the center block is adjusted. Turning the crank handle drives the rotation of the first worm gear, which in turn drives the rotation of the first worm wheel and the rotating shaft. This, in turn, drives the rotation of the second bevel gear, which in turn drives the rotation of the four first bevel gears, which in turn drives the rotation of the four lead screw guide sleeves. This causes the lead screw to move outward, which in turn moves the four fixed blocks outward. Alternatively, turning the crank handle in the opposite direction moves the four fixed blocks inward. This adjusts the distance between the fixed blocks and the center block, allowing the entire device to be adjusted according to the length of the ceramic packaging shell pins. This device is suitable for positioning and assembling various specifications of packaging shells, offering good applicability and a wider range of applications. Finally, the ceramic packaging shell pins are inserted into the corresponding pin slots.

[0018] When the bottom shell of the ceramic encapsulation housing is engaged with the central block, the weight of the bottom shell itself causes the movable rod and the first conductive plate to move downwards. When the first conductive plate moves to contact the second conductive plate, the power supply device immediately supplies power to the motor. The motor drives the rotation of the motor, and the third bevel gear drives the rotation of the four fourth bevel gears, which in turn drives the rotation of the four second worm gears. The second worm gears drive the rotation of their corresponding second worm wheels, which in turn drives the rotation of their corresponding gears. The gears drive the corresponding racks to move outwards, which in turn drives the corresponding extrusion plates to move outwards. The extrusion plates press against the inner side of the bottom shell of the ceramic encapsulation housing, thus quickly positioning the bottom shell. This invention has a simple structure, is easy to use, provides better positioning effect, and allows for rapid assembly. It is applicable to the field of electronic component sintering and processing technology. Attached Figure Description

[0040] In this invention, a mounting cavity is provided in the central block 8, and through holes communicating with the mounting cavity are provided on all four sides. A crossbar 29 is movably installed in each of the four through holes. A rack 31 is fixedly installed at one end of each of the four crossbars 29 by bolts, and an extrusion plate 28 adapted to the bottom shell 10 of the ceramic encapsulation shell is fixedly installed at the other end by bolts. A second worm gear 35 and a second worm 26 are rotatably installed on the inner walls of the mounting cavity through bearings. A gear 32 is fixedly sleeved on the outer side of any second worm gear 35 and meshes with the corresponding second worm 26. Any gear 32 meshes with the corresponding rack 31. A fourth bevel tooth 34 is fixedly sleeved on one end of each second worm 26. A motor 25 is fixedly installed on the top inner wall of the mounting cavity by bolts. A third bevel tooth 27 is fixedly sleeved on the output shaft of the motor 25. Any fourth bevel tooth 34 meshes with the third bevel tooth 27.

[0041] In this invention, a crank handle 33 is fixedly sleeved at one end of the first worm gear 14.

[0042] In this invention, a first sliding groove is provided on the bottom inner wall of any mounting hole 2, and a first slider that is fixedly connected to the corresponding lead screw 6 is slidably installed in the first sliding groove.

Turning the rocker handle 33 drives the rotation of the first worm gear 14, which in turn drives the rotation of the first worm wheel 19 and the rotating shaft 18. This, in turn, drives the rotation of the second bevel gear 16. The second bevel gear 16 then drives the rotation of the four first bevel gears 17, which in turn drives the rotation of the four lead screw guide sleeves 15. This causes the lead screw 6 to move outward, which in turn causes the four fixing blocks 12 to move outward. Alternatively, turning the rocker handle 33 in the opposite direction causes the four fixing blocks 12 to move inward. This adjusts the distance between the fixing blocks 12 and the center block 8, allowing the entire device to be adjusted according to the length of the ceramic encapsulation shell pins 9. This method is suitable for positioning and assembling various specifications of encapsulation shells, offering good applicability and a wider range of applications. Finally, the ceramic encapsulation shell pins 9 are secured into the corresponding pin slots 11.

[0048] When the bottom shell 10 of the ceramic encapsulation shell is engaged with the center block 8, the weight of the bottom shell 10 itself causes the movable rod 24 and the first conductive plate 23 to move downwards. When the first conductive plate 23 moves to contact the second conductive plate 22, the power supply device immediately supplies power to the motor 25. The motor 25 drives the rotation of the third bevel gear 27, which in turn drives the rotation of the four fourth bevel gears 34, thereby driving the rotation of the four second worm gears 26. The second worm gears 26 drive the rotation of the corresponding second worm wheel 35, which in turn drives the rotation of the corresponding gear 32. The gear 32 drives the corresponding rack 31 to move outwards, which in turn drives the corresponding extrusion plate 28 to move outwards. The extrusion plate 28 presses the inner side of the bottom shell 10 of the ceramic encapsulation shell, thus quickly positioning the bottom shell 10 of the ceramic encapsulation shell. This invention has a simple structure, is easy to use, has a better positioning effect, and allows for rapid assembly. It is applicable to the field of electronic component sintering processing technology.
