Problems solved by technology

Although the above-mentioned automatic detection line for magnetic steel thermostats can continuously detect the magnetic steel thermostats, it still requires employees to observe the triggering and reset of the magnetic steel thermostats in real time, and the labor cost is high; more importantly, It is monitored after the bimetal is assembled into the thermostat. If an unqualified thermostat is found, the bimetal of the thermostat must be disassembled for maintenance, and the maintenance cost is very high.

Embodiment 1

[0028] As shown in the figure, the bimetal automatic detection equipment of this embodiment includes a conveyor belt 1, a jump detection cabin 2, a reset detection cabin 3 and a controller (not shown in the figure, mature technology such as a single-chip microcomputer can be used as the controller ), the two detection cabins are equipped with an exit and an entrance, and an independent temperature control unit (including but not limited to heaters, temperature sensors); the conveyor belt 1 passes through the jump detection cabin 2 and reset detection sequentially along the conveying direction Cabin 3; the conveyor belt 1 is a long thin sheet structure, which is continuously driven by the driving wheel and the driven wheel, and positioning support holes 11 are arranged at intervals on it, and the depth of the positioning support holes 11 is much smaller than when the bimetal sheet 4 is placed vertically The height of jump detection cabin 2 is provided with non-jump zone 21 and j...

Embodiment 2

[0042] Such as figure 2 As shown, different from Embodiment 1, in this embodiment, there is also a transition chamber 10 that is not equipped with a heating device between the jump detection chamber 2 and the reset detection chamber 3, and the conveyor belt 1 and the second support wall 8 Pass through the transition chamber 10; the temperature of the transition chamber 10 (151°C to 167°C) is between the jump detection chamber 2 and the reset detection chamber 3; The defective product recovery area 6 below the conveyor belt 1. Because the temperature difference between the jump detection cabin 2 and the reset detection cabin 3 is relatively large, the transition cabin 10 can be set to reduce the temperature of the bimetal 4 rapidly, thereby reducing the length of the conveyor belt 1. If the bimetal 4 is in the transition cabin 10 When reset occurs, it will fall into the defective product recycling area 6 . The defective products in the defective product recovery area 6 are t...

Abstract

This invention proposes a full-automatic detection device for a bimetallic strip. Whether the jumping change temperature and the resetting temperature of the bimetallic strip meet the requirements or not can be automatically detected. The full-automatic detection device for the bimetallic strip comprises a conveying belt, a jumping change detection cabin, a resetting detection cabin and a controller; positioning supporting holes are formed in the conveying belt at intervals; the jumping change detection cabin is sequentially provided with a non-jumping-change area and a jumping-change area in the conveying direction of the conveying belt; the resetting detection cabin is sequentially provided with a non-resetting area and a resetting area in the conveying direction of the conveying belt; an inclined first supporting arm and an inclined second supporting arm are arranged on the two sides of the conveying belt correspondingly; the first supporting arm extends to the tail end of the jumping change detection cabin from the front of the jumping change detection cabin; the second supporting arm extends to the rear of the resetting detection cabin from the jumping-change area; the full-automatic detection device for the bimetallic strip is provided with unqualified product recycling areas at the positions corresponding to the non-jumping-change area and the non-resetting area, and at the tail end of the jumping change detection cabin, and the tail end of the conveying belt; and the full-automatic detection device for the bimetallic strip is provided with a qualified product recycling area at the position corresponding to the resetting area.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, and in particular relates to a bimetal automatic detection device. Background technique [0002] The bimetal sheet is also called a thermal bimetal sheet. Since the thermal expansion coefficients of each component layer are different, when the temperature changes, the deformation of the active layer is greater than that of the passive layer, so that the whole bimetal sheet will bend to the side of the passive layer. , then the curvature of the composite material changes to produce deformation. Among them, the higher expansion coefficient is called the active layer; the lower expansion coefficient is called the passive layer. Utilizing the above principles, the bimetal has been widely used in thermostats. [0003] In order to ensure the accuracy of the snap switch action, that is, to ensure that the snap switch deforms within the predetermined operating temperature range and resets wi...
