Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic packaging, and specifically discloses a metal packaging cover plate sealing automatic welding device. BACKGROUND

[0002] Traditional cover plate type metal packaging usually uses parallel seam welding equipment, which belongs to resistance welding. First, the local high temperature caused by the resistance heat effect in the welding process is easy to cause thermal damage to the packaging substrate or electronic components, especially for heat-sensitive materials (such as glass insulating substrate, polymer sealant, etc.), which may cause thermal deformation or performance degradation. Second, due to uneven distribution of welding pressure and mechanical contact limitation of seam welding electrodes, micro pores or oxidized inclusions are easy to be generated in the welding seam area, which limits the packaging air tightness level and makes it difficult to meet the vacuum packaging requirements of high reliability scenarios (such as space-level devices).

[0003] For example, the application number 2023110327201 discloses a chip packaging structure and a chip packaging method, which includes a chip and a protective cover plate. The chip has a first surface, and a functional area is formed on the first surface. The protective cover plate includes an upper cover plate and a support structure formed on the first surface of the upper cover plate. The protective cover plate is metal-bonded to the first surface of the chip, and the support structure is located between the upper cover plate and the chip. The functional area is located in the cavity surrounded by the first surface of the protective cover plate and the chip. The support structure is selected from glass.

[0004] For the welding interface of heterogeneous materials, brittle intermetallic compounds are easy to form, which significantly reduces the fatigue resistance of the joint. At the same time, the fluctuation of contact resistance caused by electrode wear during the welding process will affect the consistency of the welding seam, which may cause welding through or virtual welding defects in miniaturized packaging. In high-frequency welding operations, electromagnetic interference affects the surrounding precision circuit, and it is difficult to achieve uniform melting of complex curved or asymmetric structure cover plates, which further limits its applicability in advanced packaging fields. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a metal packaging cover plate sealing automatic welding device to solve the technical problems of thermal damage, poor material compatibility, and insufficient sealing of traditional packaging methods.

[0006] In order to achieve the above object, the present application provides the following technical scheme: a metal packaging cover plate sealing automatic welding device, comprising a first base and a third base, a connecting column is arranged on the first base, a rotating device is arranged on the connecting column, a fixing frame is arranged at the output end of the rotating device, a workbench is fixedly connected to the fixing frame, and a packaging mechanism for packaging is arranged in the workbench; a table top is arranged on the workbench, and a processing assembly is placed on the table top; an upper feeding mechanism for moving the processing assembly to the packaging mechanism is arranged on the third base. The processing assembly is moved to the packaging mechanism by the upper feeding mechanism, and then the metal cover plate is welded on the electronic component base by the packaging mechanism, so that the welding work of the electronic component base and the metal cover plate is completed, and a plurality of electronic component bases and metal cover plates can be welded at one time, so that the processing efficiency can be improved.

The partition plate is arranged between the first carrier plate and the second carrier plate, and the partition plate has a certain distance when the metal cover plate moves, so that the metal cover plate can impact on the electronic component base at a very high speed.

[0009] Further, the feeding mechanism comprises a clamping frame fixedly connected to the third base, a plurality of groups of first fixing blocks are arranged on the two sides of the clamping frame, and a movable frame is arranged between the plurality of groups of first fixing blocks; a sliding groove is formed in the first fixing block, and inclined blocks are fixedly connected to the two sides of the movable frame, and the two groups of inclined blocks are slidably clamped in the plurality of groups of sliding grooves.

[0011] Further, two groups of limiting blocks are fixedly connected to the movable frame, a limiting groove is formed in the first loading plate, and the two groups of limiting blocks are slidably clamped in the two groups of limiting grooves; a second connecting block is arranged on the clamping frame, a rotatable roller is arranged on the roller, and the roller is in contact with the second loading plate. The roller can limit the second loading plate, the limiting block can limit the first loading plate, so that the processing assembly is fixed on the movable frame, and when the processing assembly needs to be separated from the movable frame, the processing assembly is fixed, the movable frame is horizontally moved, and the processing assembly is separated from the movable frame.

[0012] Further, a clamping mechanism is arranged on the first base, the clamping mechanism comprises a pneumatic cylinder, a second base is fixedly connected to the first base, the pneumatic cylinder is fixedly connected to the second base, a first matching block is fixedly connected to the extension end of the pneumatic cylinder, a rotatable second matching block is arranged on the first matching block, a clamping block is fixedly connected to the second matching block, and the clamping block is in contact with the first loading plate.

The material taking mechanism can move the first loading plate to a specified position, and a worker performs subsequent processing.

[0014] The working principle and beneficial effects of the present scheme are that:

[0015] In use, the worker first fixes the processing assembly on the feeding mechanism, moves the processing assembly to the table top through the feeding mechanism, then the worker starts the cylinder to drive the clamping block to fix the processing assembly on the table top, then removes the feeding mechanism from between the clamping block and the table top, and the packaging mechanism welds the metal cover plate on the electronic component base through the packaging mechanism. When welding, the shaped coil discharges rapidly, generates a peak pulse current with extremely high value instantaneously, and generates a huge Lorentz force to drive the metal cover plate to move at an ultra-high speed. The metal cover plate passes through the fixing groove and collides with the electronic component base at a high speed. The extremely high pressure and metal jet generated in the instant collision act to remove the surface contamination layer and promote the metallurgical combination between the two clean metal surfaces in the solid state, thereby completing the welding of the metal cover plate and the electronic component base.

[0016] When welding the metal cover plate, there is a copper foil between the electromagnetic pulse welding device and the metal cover plate, which is used for temporary electromagnetic shielding. The copper foil distorts the internal magnetic field distribution of the device to prevent significant interference to the electronic component base during electromagnetic pulse welding. Moreover, the copper foil only covers the non-functional area and does not affect the normal welding of the electronic component base and the metal cover plate. BRIEF DESCRIPTION OF DRAWINGS
