Method for detecting balance degree of pressure-maintaining equipment and pressure-maintaining device

Abstract

The invention is applicable to the field of detection equipment, and discloses a method for detecting the balance degree of pressure-maintaining equipment. The method comprises the following steps: enabling gummed paper to be pre-attached to the surface of an object to be subjected to pressure maintaining, and enabling the object to be subjected to pressure maintaining to be placed in the pressure-maintaining equipment; using the pressure-maintaining equipment for acting on the gummed paper and maintaining the pressure of the object to be subjected to pressure maintaining, so that the gummed paper is different in attaching tightness with the surface of the object to be subjected to pressure maintaining and presents different states, and the balance degree between the pressure-maintaining equipment and the object to be subjected to pressure maintaining is judged according to the state of the gummed paper. The invention further provides a pressure-maintaining device. The pressure-maintaining device comprises the pressure-maintaining equipment and the gummed paper, wherein the gummed paper can be pre-attached to the object to be subjected to pressure maintaining, is different in attaching tightness with the surface of the object to be subjected to pressure maintaining and presents different states. According to the method for detecting the balance degree of the pressure-maintaining equipment and the pressure-maintaining device, the gummed paper is attached to the surface of the object to be subjected to pressure maintaining, and after pressure maintaining is conducted on the object to be subjected to pressure maintaining, the balance degree of the pressure-maintaining equipment is judged according to different states presented by the gummed paper.

Description

technical field [0001] The invention belongs to the field of detection equipment, and in particular relates to a detection method for the balance degree of pressure-holding equipment and a pressure-holding device. Background technique [0002] The pressure holding equipment can exert a certain pressure on the items to be held. It is often used in the assembly and testing of various products, especially in the production and assembly process of electronic products. [0003] Pressure holding equipment can be divided into those with automatic calibration and balance function and those without automatic calibration function. Among them, the structure of pressure holding equipment with automatic calibration function is relatively complicated and the price is high. In order to control product costs, many manufacturers will choose relatively low-cost non- Pressure holding equipment with automatic calibration function. During the use of this kind of pressure holding equipment, it wi...

[0003] Pressure holding equipment can be divided into those with automatic calibration and balance function and those without automatic calibration function. Among them, the structure of pressure holding equipment with automatic calibration function is relatively complicated and the price is high. In order to control product costs, many manufacturers will choose relatively low-cost non- Pressure holding equipment with automatic calibration function. During the use of this kind of pressure holding equipment, it will generally judge whether the balance of the pressure holding equipment is normal through the state of a large number of finished products. The accuracy and convenience of this detection method are not good. Hidden dangers to subsequent product quality
