Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum substrate production, and particularly relates to a pre-treatment device for aluminum substrates before pressing. Background Art

[0002] An aluminum substrate is a metal-based copper clad laminate with good heat dissipation function. Generally, a single-sided board consists of three layers, namely a circuit layer (copper foil), an insulating layer, and a metal base layer. There are also double-sided boards designed for high-end use, with a structure of circuit layer, insulating layer, aluminum base, insulating layer, and circuit layer. Very few applications are multi-layer boards, which can be formed by laminating ordinary multi-layer boards with insulating layers and aluminum bases. The insulating layer is the core technology of the aluminum substrate, mainly playing the functions of bonding, insulation, and heat conduction. The insulating layer of the aluminum substrate is the largest heat conduction barrier in the power module structure. The better the heat conduction performance of the insulating layer, the more conducive it is to the diffusion of heat generated during the operation of the device, the more conducive it is to reducing the operating temperature of the device, thereby achieving the purposes of improving the power load of the module, reducing the volume, extending the service life, and increasing the power output. Before pressing the existing aluminum layer board, in order to prevent the burrs on the aluminum layer board from piercing the insulating layer and copper layer during the pressing process, pre-treatment is carried out on the aluminum layer board through a pre-treatment device to perform burr treatment on the aluminum layer board. However, the cleaning treatment of the existing pre-treatment device is not thorough enough. Therefore, a new pre-treatment device for aluminum substrates before pressing is needed. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a pre-treatment device for aluminum substrates before pressing, which solves the problems in the above background art.

[0004] The purpose of the utility model is achieved as follows: A pre-treatment device for aluminum substrates before pressing, which includes a cylinder body. A support assembly is arranged at the lower end of the cylinder body. The upper end of the cylinder body has no top cover. A liquid outlet is arranged at the lower end of the cylinder body. An alkaline solution is contained inside the cylinder body. A treatment assembly is arranged above the cylinder body. The treatment assembly includes a left vertical plate and a right vertical plate fixedly connected to the side wall of the upper end of the cylinder body and extending upward. An immersion assembly is arranged between the left vertical plate and the right vertical plate. The immersion assembly is connected with a driving assembly. When in use, the aluminum layer board of the aluminum substrate is clamped and placed on the bearing plate of the immersion assembly. The driving assembly is used to drive the immersion assembly to move. During the movement of the immersion assembly, the aluminum layer board is driven to move synchronously, so that the aluminum layer board is immersed in the alkaline solution inside the cylinder body during the movement. There is sodium hydroxide in the alkaline solution. The strong alkalinity of the sodium hydroxide solution is used to corrode the surface of the aluminum layer board, smooth the slight burrs, and achieve the removal of the burrs on the surface of the aluminum layer board, making the burr cleaning of the aluminum layer board more thorough.

[0005] Further, the immersion liquid assembly includes a horizontal shaft. The left end of the horizontal shaft is rotatably connected to the left vertical plate. The right end of the horizontal shaft penetrates through the right vertical plate and extends to the outside of the right vertical plate, and the horizontal shaft is rotatably engaged with the right vertical plate.

The plug socket is detachably connected with a plurality of extension rods, and a clamping component is arranged at the outer end of the extension rod. The clamping component includes a bearing plate fixedly connected to the outer end of the extension rod. An outer folding part is fixedly arranged on the side wall of the bearing plate. A clamping groove is formed in the outer folding part, and a plurality of clamping ridges are fixedly arranged on the inner side wall of the clamping groove. Through the arrangement of the outer folding part and the clamping groove, it is convenient for the aluminum layer board to be stuck to the side wall of the bearing plate, and the installation and disassembly of the aluminum layer board are convenient. Through the arrangement of the clamping ridges, the friction between the aluminum layer board and the clamping groove is increased, and the aluminum layer board is clamped and fixed more firmly.

[0006] Further, the driving component includes a support plate fixedly connected to the outer side wall of the cylinder body. A motor is fixedly arranged at the upper end of the support plate. The output shaft of the motor is connected to the right end of the horizontal shaft. During use, the motor is started to drive the horizontal shaft to rotate. The rotation of the horizontal shaft drives a plurality of bearing plates to be alternately immersed in the caustic solution. The aluminum layer board is driven to be immersed in the caustic solution by electric energy, reducing the working intensity of the operators.

[0007] Further, the support component includes a first support rod, a second support rod and a third support rod, and the first support rod, the second support rod and the third support rod are all inclined. Their upper ends are fixedly connected to the lower end of the cylinder body. There are four extension rods, and the four extension rods have the same specifications. The four extension rods are arranged in an equidistant circular arrangement around the outer circumference of the horizontal shaft. There are three clamping ridges, and the three clamping ridges are fixedly arranged side by side on the inner top wall of the clamping groove.

[0008] The beneficial effects of the present utility model are as follows: By using the strong alkalinity of the sodium hydroxide solution to corrode the surface of the aluminum layer board, the slight burrs are smoothed, realizing the removal of the burrs on the surface of the aluminum layer board, making the burr cleaning of the aluminum layer board more thorough, reducing the working intensity of the operators and improving the working efficiency. During use, the motor is started to drive the horizontal shaft to rotate. The rotation of the horizontal shaft drives a plurality of bearing plates to be alternately immersed in the caustic solution. The aluminum layer board is driven to be immersed in the caustic solution by electric energy, reducing the working intensity of the operators. The aluminum layer board of the aluminum substrate is clamped and placed on the bearing plate of the immersion liquid assembly. By the action of the driving component, the immersion liquid assembly is driven to move. During the movement of the immersion liquid assembly, the aluminum layer board is driven to move synchronously, so that the aluminum layer board is immersed in the caustic solution inside the cylinder body during the movement, completing the cleaning and removal of the burrs. Through the arrangement of the outer folding part and the clamping groove, it is convenient for the aluminum layer board to be stuck to the side wall of the bearing plate, and the installation and disassembly of the aluminum layer board are convenient. Through the arrangement of the clamping ridges, the friction between the aluminum layer board and the clamping groove is increased, and the aluminum layer board is clamped and fixed more firmly.
