The utility model has the advantages of realizing the automatic aluminum spraying, spraying aluminum homogeneously, having high productive efficiency, saving energy, reducing the waste, and reducing the production cost and the like.
Description
Technical field
The utility model belongs to the manufacture technology field of piezoresistive wafer, is specifically related to the automatic aluminium-plated machine of a kind of piezoresistive wafer.
Background technology
Piezoresistive wafer both ends of the surface aluminium-plated is the important procedure in the resistor disc production process, by aluminium-plated, can form the firm metal aluminium lamination of one deck bonding on the resistor disc surface, form electrode, this electrode layer can make the high-tension current that is applied on the resistor disc evenly distribute in lamellar body inside and pass through.Existing aluminium-plated be to adopt vertical spraying, being about to resistor disc vertically is stuck on the rotating disk, rotate rotating disk during spraying, majority is by manually holding spray gun, make it parallel with horizontal plane, spraying then, the shortcoming of this spraying coating process is that to be subjected to gravity effect be not to scatter to the four sides to the aluminium powder after the spray gun ejection, but the trend of falling is downwards arranged, if if the pressure less stable of spray gun will directly cause the aluminium electrode that sprays inhomogeneous.Hand spray is because artificial factor causes the non-uniform phenomenon in the spraying process.If the inhomogeneous or spraying of electrode layer spraying is thin, thicker, cause easily all that resistor disc its surface when square-wave test is breakdown, through-current capability reduces.In addition, hand spray efficient is lower, cost height (monolithic raw material and energy consumption cost are up to 0.47 yuan), and the amount of labour is big, and bigger to operator's health effect.Therefore, prior art exists: aluminium-plated inhomogeneous, the resistor disc poor performance is breakdown easily, and through-current capability reduces, and production efficiency is low, and consumable quantity is big, the deficiency of manufacturing cost height.
Summary of the invention
The purpose of this utility model is that design is a kind of can be aluminium-plated automatically, aluminium-plated evenly, can alleviate labor strength, production efficiency height, the automatic aluminium-plated machine of energy-saving and cost-reducing piezoresistive wafer.
For achieving the above object, the main technical schemes that the utility model adopted is to change existing vertical spraying into the plane spraying, conveyer promptly is set, aluminium-plated device, the conveyer belt level of body conveyer is contained on the body, aluminium-plated device vertically is located on the body of top of conveyer belt, thereby constitutes the automatic aluminium-plated machine of a kind of piezoresistive wafer.
Adopt such scheme, the spray gun of aluminium-plated device is contained on the guide rail, can move along guide rail, and make spray gun vertical with horizontal plane, then resistor disc is placed on the conveyer belt side by side, the conveyer belt direction of transfer is vertical with the moving direction of spray gun on guide rail, like this when side by side resistor disc moves forward to the spray gun below along with conveyer belt, because the translational speed of spray gun is more faster than the transfer rate of conveyer belt, therefore can realize even spraying to whole row's resistor disc surfaces of aluminum electrode layer.This improved benefit is that effectively to have eliminated the spraying that causes owing to gravity effect inhomogeneous, and when guaranteeing aluminium-plated effect, improved the automaticity of production efficiency (Φ 60mm model resistor disc can realize per hour spraying 9000) and aluminium-plated operation greatly, (250,000 yuan of scrap build expenses, 0.25 yuan of the aluminium-plated process energy consumption of monolithic and the cost of raw material) with low cost.Owing to be provided with two aluminium-plated devices, when an end face is aluminium-plated finish after, manually only need the resistor disc turn-over, with the transmission of conveyer belt, another aluminium-plated device can be finished the aluminium-plated of other end, has alleviated working strength of workers.Compared with prior art, have can realize aluminium-plated automatically, aluminium-plated evenly, the production efficiency height, energy-saving and cost-reducing, remarkable advantage such as reduce production costs.
