The invention discloses an EGR corrosion-resistant pressure sensor packaging device and a method of using the same. The packaging device includes a worktable, and an assembly part is arranged on the worktable. The assembly part includes a moving part and a rotating part, and a fixed part is fastened on the worktable. The pressure sensor includes a first casing, a clamping block is arranged on the first casing, a fixing block is arranged in the first casing, a second casing is arranged on the first casing, and the first casing is connected with the first casing. A chip is arranged between the two shells, and a mounting mechanism for assembling a fixing block is arranged on the packaging device. The mounting mechanism includes a conical block, a horizontal plate and a placing plate. The fixing piece is provided with a second hydraulic rod. The output end is tightly connected with the conical block, the placing plate is located above the horizontal plate, and the horizontal plate is rotatably connected with the moving part. The packaging device of the invention separately locates and installs each component of the pressure sensor, has good positioning effect and high accuracy, the fixing block fastens the chip, the operation is simple, and the pressure sensor chip is protected.
Description
technical field [0001] The invention relates to a packaging device, in particular to an EGR corrosion-resistant pressure sensor packaging device and a method of using the same. Background technique [0002] A pressure sensor is a device or device that can sense the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule. The pressure sensor is usually composed of a pressure sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. Pressure sensor is one of the most commonly used sensors in industrial practice, and it is widely used in various industrial automatic control environments. [0003] The existing pressure sensor packaging and positioning effect is poor, the assembly of parts in the packaging process is troublesome, and the processing efficiency is low, ...
