Description

Technical Field

[0001] The utility model relates to the field of crystal bonding machines, in particular to a feeding device for a crystal bonding machine. Background Art

[0002] A crystal bonder is a device used to solidify crystals. It is mainly used to prepare crystal materials, such as silicon wafers, semiconductor crystals, etc. Crystal bonders are usually used in the semiconductor industry and optoelectronics industry to produce various electronic and optical devices. When a crystal bonder is in production, a loading device is required for loading.

[0003] The existing feeding device of the crystal bonding machine places the material tray under the adsorption part, and then moves the adsorption part downward to adsorb the material from the material tray to load the crystal bonding machine. However, since the position of the adsorption part is fixed, when the material tray model is different, the position of the material may also be different, resulting in the adsorption part being unable to adsorb the material.

[0004] Therefore, a feeding device for a die bonder has been developed which can adjust the position of a rubber sleeve so as to adapt to different types of trays. Utility Model Content

[0005] In order to overcome the disadvantage of the existing crystal bonder feeding device that the position of the material may be different when the material tray model is different, resulting in the adsorption part being unable to adsorb the material, the utility model provides a crystal bonder feeding device which can adjust the position of the rubber sleeve to adapt to different types of material trays.

[0006] Technical solution: A feeding device for a crystal bonding machine includes a base plate, a trackless cylinder, a sliding frame, an electric push rod, a connecting frame and a mounting plate. The rear side of the base plate is connected to the trackless cylinder, the sliding frame is slidably connected to the trackless cylinder, the upper part of the sliding frame is connected to the electric push rod, the telescopic end of the electric push rod is connected to the connecting frame, and the lower side of the connecting frame is connected to the mounting plate.

[0007] As an improvement of the above solution, it also includes limit bars. The upper sides of the front and rear parts of the bottom plate are connected with left and right limit bars. The material tray is limited by the limit bars to prevent the material tray from moving.

[0008] As an improvement to the above solution, the limiting strips are all L-shaped structures.

[0009] As an improvement of the above scheme, it also includes a ventilation pipe, a sleeve and a rubber sleeve. A plurality of groups of grooves are opened on the mounting plate, each group consists of nine grooves, and a ventilation pipe is slidably connected between the grooves of each group. A plurality of sleeves are connected to the ventilation pipe, and a plurality of rubber sleeves are connected to the lower side of the ventilation pipe. The mounting plate is moved downward so that the rubber sleeve contacts the material, and then the vacuum pump is started to put the ventilation pipe in a vacuum state so that the material is adsorbed on the rubber sleeve.

[0010] As an improvement of the above solution, the ventilation pipe is made of a hose material.

[0011] As an improvement of the above scheme, it also includes nuts, the sleeves are all threadedly connected with nuts, the nuts are all in contact with the mounting plate, so that the nuts are re-contacted with the mounting plate to fix the ventilation pipe.

[0012] The utility model rotates the nut to move the nut upward on the sleeve to separate from the mounting plate, and then slides to adjust the position of the vent pipe on the groove so that the rubber sleeve corresponds to the position of the material on the material tray, thereby achieving the effect of being able to adjust the position of the rubber sleeve to adapt to different types of material trays.
