Abstract

The invention discloses an automatic protection type multipath motormeter point crimping device and method and belongs to the field of mechanical and electronic integration. The problem that due to the manual crimping mode of an existing motormeter point crimping device, a motormeter is damaged easily when pressed is solved. The alarm control signal input end of an alarm circuit is connected with one switch signal output end of a relay set. The other switch signal output end of the relay set is connected with the switch control signal input end of a solenoid valve switch. The control signal input end of the relay set is connected with the control signal output end of a central processing unit. The detection pressure signal output end of a sensor module is connected with the analog signal input end of a transmitter module. The digital signal output end of the transmitter module is connected with the pressure signal input end of the central processing unit. The pressure signal output and control signal input end of the central processing unit is connected with the pressure signal input and control signal output end of a computer. The switch value signal output end of the solenoid valve switch is connected with the switch signal input end of a stroke air cylinder. The automatic protection type multipath motormeter pointer crimping device and method are suitable for crimping of motormeter pointers.

Description

technical field

[0001] The invention belongs to the field of mechatronics. Background technique

[0002] The traditional crimping method is manual crimping. There is no precise control of the pressure, resulting in damage to the motor, dial, and pointer when the pressure is too high. The central shaft will cause damage to the main shaft and seriously affect the product qualification rate. At the same time, only one watch needle can be crimped at one time, and multiple crimping is required when pressing a multi-pointer instrument. Contents of the invention

[0003] In order to solve the problem that the manual crimping method of the existing automobile meter pointer crimping device easily causes the car meter to be crushed, the present invention proposes an automatic protection type multi-channel car meter pointer crimping device and a crimping method.

[0004] The automatic protection type multi-channel automobile meter pointer crimping device of the present invention in...
