specific Embodiment approach 1
[0036] Specific implementation mode one: refer to figure 1 and 2 Specifically explaining this embodiment, the pressure feedback-based fully automatic pointer pressing method described in this embodiment includes the following steps:
[0037] Collect the information of the previous station and judge whether the information of the previous station is qualified. When the information of the previous station is qualified, start to execute step 1, otherwise stop the pressing.
[0038] Step 1: During the pressing process of the pointer, the pressure between the pointer cap and the end of the motor shaft is collected in real time,
[0039] After collecting the pressure between the pointer cap and the end of the motor shaft, delay 50ms and then perform step 2.
[0040] Step 2: Calculate the corresponding pressing depth of the pointer cap in real time according to the pressure,
[0041] Step 3: Within the standard pressure range, when the press-fit depth of the pointer cap correspond...
specific Embodiment approach 2
[0049] Embodiment 2: The pressure feedback-based fully automatic pointer pressing system described in this embodiment includes the following modules:
[0050] Initialize the module:
[0051] Collect the information of the previous station, and judge whether the information of the previous station is qualified,
[0052] When the information of the last station is qualified, start the pressure acquisition module,
[0053] When the information of the previous station is unqualified, the driver will alarm.
[0054] Pressure acquisition module: During the pointer press-fitting process, the pressure between the pointer cap and the end of the motor shaft is collected in real time,
[0055] Delay module: After collecting the pressure between the pointer cap and the end of the motor shaft, delay 50ms before starting the pressing depth acquisition module.
[0056] Pressing depth acquisition module: Calculate the corresponding pointer cap pressing depth in real time according to the p...

Abstract
The invention discloses a full-automatic pointer press-fitting system and method based on pressure feedback, and relates to the technical field of instrument assembly. The system and method aim to solve the problems of large pressure deviation and large pointer height deviation due to adoption of a fixed height press-fitting mode in the prior art of instrument press fitting. According to the full-automatic pointer press-fitting system and method, in order to ensure product consistency, according to the principle that the actual pressure reacts in real time on the pointer height, the pressure and the pointer height are comprehensively considered, and the pressure and the pointer height are guaranteed to meet the control requirement; and meanwhile, the pressure and the press fitting depths are subjected to quantitative model establishment, the press fitting depths are divided into five stages, and the relationships between the five stages of press fitting depths and the pressure are established correspondingly. The method can reduce the pressure deviation and the pointer height deviation, and can improve the product quality while ensuring the product consistency.
Description
technical field [0001] The invention belongs to the technical field of instrument assembly, and in particular relates to press-fitting of instrument pointers. Background technique [0002] Pointer press-fitting is an important process in the assembly of automobile instruments, and all manufacturers are committed to developing the most reliable press-fitting method to ensure assembly quality. Most of the existing pointer press-fitting adopts the method of fixing the press-fitting height, that is, it is considered that the friction between the pointer shaft and the motor shaft of each instrument is exactly the same. The actual situation is that each set of instruments cannot be completely consistent due to factors such as the gap between the structural parts and the position of the motor shaft. With the continuous improvement of product quality requirements of OEMs, the fixed-height press-fitting method will lead to large pressure deviations and pointer height deviations, whi...
