Description

A bar device for preventing the inclination of the material box in AD8312 equipment

technical field

The invention belongs to the technical field of semiconductor packaging, in particular to a bar device for preventing the inclination of a material box in AD8312 equipment.

Background technique

The semiconductor production process consists of wafer fabrication, wafer testing, chip packaging, and post-package testing. Semiconductor packaging and testing refers to the process of processing the tested wafers to obtain independent chips according to the product model and functional requirements. There are as many as dozens of types of equipment popular in the die placement (DA) section of the semiconductor packaging field. According to the manufacturer, there are HITACHI, SHINKAWA, ESEC, ASM, ACCURACY and so on. The operating principles of the above-mentioned companies' equipment are similar. Feeding, dispensing, film loading, and output to the magazine (magazine), most of the film loading operates according to this process.

ASM AD8312 is a high-speed chip loading machine developed and designed by ASM company that can process 12-inch wafers. It has high UPH, stable glue drawing and loading operations, simple and easy-to-learn operation, and is very suitable for small and medium-sized chips in packaging factories. widely. However, in the actual production process of each packaging factory, when the magazine is unloaded from the unloader (magazine unloader), the frame in the magazine unloader will be impacted and deformed, and the magazine will be tilted on the unloading platform or even when the magazine is being replaced. The tilting of the material box occurs when the box is loaded. Due to the unreasonable design of the retaining bar for fixing the material box on the original discharge platform of the AD8312, the position of the bar is too low and fixed in the X-axis direction, and the material boxes of different sizes all use the same retaining device, which cannot be used to fix the material box. to great effect. When the material box is transported to the position of the loader cylinder through the belt at the bottom of the platform, the material box will tilt, and the frame in the material box will slide out of the material box. When the gap between the material box and the equipment is too large, manually push it horizontally When loading the material box, if the frame leaks out, it will hit the equipment and cause the frame to deform.

In order to solve the above technical problems, the present invention proposes a bar device for preventing the inclination of the material box in AD8312 equipment, including: a rectangular bar body, a horizontal chute in the X-axis direction, a slider, and a fixed screw knob on the slider And the threaded through hole for the screw knob to pass through, wherein the bar body is vertically fixedly connected with the slider, the slider is stuck in the horizontal chute and can slide left and right in the X-axis direction, and at the same time, in the Y-axis direction, the bar The body is set at 1/3~1/2 of the height of the material box. By changing the position of the bar body in the X and Y axis directions, the material box is better fixed and closer to the side of the equipment, preventing the material box from tilting and causing the frame to leak out and hit the side of the equipment, resulting in deformation and scrapping.

Contents of the invention

A bar device for preventing the inclination of the material box in AD8312 equipment, comprising: a rectangular bar body 1, a transverse chute 2 in the X-axis direction, a slider 3, and a fixed screw knob 31 and a supply screw knob 31 are arranged on the slider 3 The threaded through hole 32 passed through, wherein the bar body 1 is vertically fixedly connected with the slider 3, the slider 3 is stuck in the transverse chute 2 and can slide left and right in the X-axis direction, and at the same time, in the Y-axis direction, the gear The bar body 1 is set at 1/3-1/2 of the height of the material box.

By setting the transverse chute 2 and the slider 3 device, the bar body 1 fixedly connected to the slider 3 can move left and right in the X-axis direction according to the size of the material box, and the bottom of the screw knob 31 can be rotated by turning the screw knob 31. The end is in close contact with the bottom end of the transverse slide groove 2, and the position of the bar body 1 in the X-axis direction is fixed by the friction generated by the pressure in the vertical direction. This setting makes the material box closer to the equipment, thereby reducing the distance between the side of the material box and the equipment, so that the material box will not tilt during the loading process, so that the frame leaks out and hits the side of the equipment, resulting in deformation and scrapping. Secondly, the position of the original bar body 1 in the AD8312 device is lower, which cannot effectively fix the material box. In this way, when the material box is conveyed by the belt at the bottom of the platform to the position of the loader cylinder, the material box will tilt. After the bar body 1 is set at 1/3~1/2 of the height of the material box, it can play a good role in fixing the material box as a whole, and the material box will not be tilted due to friction, inertia, etc. during the transmission process. In addition, the material box is close to the equipment, so the frame in the material box will not hit the side of the equipment and be deformed and scrapped.

Preferably, the bar device for preventing the inclination of the material box in the AD8312 equipment has one or two symmetrical "L" shaped bar brackets 11 on the bar body 1 . Due to the limited contact area between the rectangular bar body 1 and the material box and the position of the bar in the Y-axis direction is fixed, when the size of the material box changes greatly, the position of the bar in the Y-axis direction cannot be realized. Effective fixation of the material box. When one or two symmetrical "L" shaped bar brackets 11 are provided on the bar body 1, the effective area between the bar and the material box can be increased, and the fixing effect of the material box is significantly improved, and the material box is loaded And there will be no inclination during the transmission process.

Preferably, the bar device for preventing the inclination of the material box in the AD8312 equipment, the bar body 1 and the bar bracket 11 are made of stainless steel, and at the position in contact with the material box, outside the bar body 1 and the bar bracket 11 Wrapped in plastic. The stainless steel material is widely used and the rigidity is relatively high. The contact position between the bar body 1 and the bar bracket 11 and the material box is set with plastic, which can avoid metallic friction between the bar device and the material box, and prolong the service life of the material box and the bar device. .

Preferably, the bar device for preventing the inclination of the material box in the AD8312 equipment, the bar body 1 and the bar bracket 11 are hollow structures, so that the bar device is lightweight.

Preferably, the bar device for preventing the inclination of the magazine in the AD8312 equipment is provided with a plurality of threaded blind holes 21 that can be matched with the screw knob 31 at the bottom of the transverse chute 2 . Screwing the screw knob 31 into the threaded blind hole 21 can make the position of the bar in the X-axis direction more stable. The threaded blind hole 21 at the corresponding position in the X-axis direction can be selected according to the size of the different material boxes to fix the bar.
