Description

Bistable electronic sensor aging detection device

Technical Field

The invention relates to the technical field of mechanical equipment, in particular to a bistable electronic sensor aging detection device.

Background

Many types of devices and systems exhibit inherently reduced failure rate characteristics over an early lifetime. The relatively high early failure rate is generally attributed to the inherent uncertainty in the production process. Aging has long been recognized as an effective method of detecting and eliminating early failure of components or systems prior to delivery. Without aging, defective parts may be delivered to the user's hands, resulting in expensive field repairs and reputational damage. Sensors, like other products, can fail for various reasons at any time, and some have defective failures, such as short/open circuits, that cause the product to fail to operate properly. The potential defects cause the product to be temporarily usable, but in use, the defects are quickly exposed, and the product cannot work normally. The aging detection is to eliminate the potential unqualified sensors which may fail early, so that the sensors can work under load to cause defects to appear in a short time, and faults are avoided in use. The aging can remove the defective products as early as possible so as to carry out corresponding technical improvement, and the aging is an important means for quality control.

The traditional aging test method is to arrange a post, the tester manually ages the sensor, the aging test method needs to consume a large amount of manpower and material resources, the working efficiency is not high, the aging performance can not be accurately controlled even if aging is passed, and the long-time running stability of the product can not be ensured.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 3, in order to ensure the accuracy and reliability of the detection, the aging detection device 2 is disposed in a housing 1, the housing includes a housing frame 13 and a plurality of panels 14 for sealing the housing frame 13 and forming a closed cavity therein, the panels located on the front side are arranged as a split door structure, and a handle structure is disposed on the outer surface of the panels. The closed cavity in the shell is divided into an upper detection cavity and a lower power cavity by a middle crosspiece.

The internal surface of panel is provided with a plurality of and detects position 11, and the surface electricity is connected and is provided with and detects the count indicating assembly that 11 quantity of position correspond, according to size and occupation space's rationality, proposes to detect the position and sets up quantity and control for 300, detects the position including detecting the contact and being used for the detection seat of fixed product.

An aging detection device 2 is movably arranged in the accommodating cavity of the shell 1, and the aging detection device 2 is driven by the driving component 3 to carry out aging detection on the bistable electronic sensor 12 on the detection position 11.

Aging detection device 2 includes mounting bracket 21 and sets up a plurality of magnets 22 on the mounting bracket, and mounting bracket 21 is frame rack construction, and the equipartition has a plurality of magnets 22 on the frame crosspiece that is located on the outer peripheral face of frame, and the quantity that sets up of magnet sets up according to operating condition.

Drive assembly 3 sets up in the power cavity, including driving motor 31, drive connection 32, guide bar 33, driving motor 31 passes through mounting panel 34 to be fixed at the lower extreme of casing skeleton, drive connection 32 includes the connecting rod, the ejector pin passes through fixing mechanism to be fixed on the lower frame crosspiece of mounting bracket, be provided with the guide bar inserted block on the frame crosspiece of mounting bracket, the both ends of guide bar 33 are fixed in on the middle crosspiece of casing skeleton 13, when making the mounting bracket be the up-and-down motion by drive assembly 3 drive, can only follow the direction action of guide bar, make mounting bracket 21 when being the up-and-down motion, it is more steady.

When the mounting bracket is driven by the driving component 3 to move up and down, the auxiliary balancing component can adjust the gravity balance of the mounting bracket and reduce the output power of the driving component, and the auxiliary balancing component comprises a pulley 41, a chain 42 and a balance block 43. Pulley 41 includes first pulley and second pulley, all be fixed in on casing skeleton 13 through fixing device, wherein first pulley position sets up in the center department of mounting bracket, at the vertical support chassis that adds in mounting bracket middle part, the chain 42 is fixed in the junction of crosspiece and support chassis in the middle of the mounting bracket, guarantee the bearing capacity of mounting bracket and the weight balance when going up and down, the chain passes through first pulley and second pulley in proper order after, the end is vertical to hang down and is equipped with a balancing piece 43, be located the gravity of the control balancing piece of being convenient for, we adopt the weight as gravity balance mechanism.

When the driving component 3 outputs power to jack up the mounting frame upwards, the weights can act downwards due to jacking of the mounting frame, and therefore stress balance of the whole frame is achieved.
