[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0031] As Figures 1-5 shown, in one embodiment, a sensor dynamic aging test equipment includes: an aging workbench 1, the aging workbench 1 is divided into multiple layers by a fixed plate 11, and product fixing devices 2 are symmetrically arranged on the fixed plate 11 for installing and fixing the product to be tested; a movement device 3 is arranged between the product fixing devices 2 for driving the induction block 5 to reciprocate; circuit control devices 4 are symmetrically arranged outside the product fixing devices 2 for monitoring the test circuit.

[0032] Furthermore, a display screen 8 is arranged on one side of the aging workbench 1, and a switching power supply 9 is arranged on the top of the aging workbench 1.

[0033] Exemplarily, the aging workbench 1 is divided into 4 layers, with 2 rows of product fixing devices 2 on each layer and 24 products in each row. Thus, 192 products can be aged simultaneously, and different categories or batches of products can be aged in a hierarchical control manner. It is overall flexible and efficient, saves space, and is suitable for batch product aging.

[0034] As Figures 1-5 shown, in this embodiment, the product fixing device 2 includes an operating handle 21, an elastic telescopic clip 22, and a V-shaped fixing seat 23. Among them, the operating handle 21 is arranged at the top of the fixing seat 23, and the elastic telescopic clip 22 is arranged in the middle of the fixing seat 23. During the test, the operating handle 21 is toggled to drive the elastic telescopic clip 22 to fix the product to be tested mounted on the V-shaped fixing seat 23.

[0035] Furthermore, the fixing seat 23 is also provided with a rubber pad 24, which plays a role in buffering and reducing the impact force.

[0036] As Figures 1-5 shown, in this embodiment, the motion device 3 includes a guide rail 31, a motor 32, and a cam 33. Among them, the motor 32 is fixed at one end of the fixing plate 11, and the motor 32 is connected with the cam 33. The cam 33 abuts against the guide rail 31, and a spring 34 is also connected to the middle of the guide rail 31. During the test, the motor 32 drives the cam 33 to rotate to drive the guide rail 31 to move, and cooperates with the spring 34 to drive the guide rail 31 to reset, realizing the reciprocating telescopic motion of the guide rail 31.

[0037] Furthermore, two rows of induction blocks 5 are equidistantly installed on the guide rail 31, which are respectively paired with the centers of the products to be tested on both sides. The state of the products is cyclically switched through the telescopic motion of the guide rail 31.

[0038] As Figures 1-5 shown, in this embodiment, the circuit control device 4 includes a wiring seat 41 and a signal indicator light 42. Among them, each circuit control device 4 can be connected to multiple products to be tested, and each row corresponds to multiple circuit control devices 4.

[0039] Exemplarily, when some products have problems, the power supply of this circuit can be locally controlled and disconnected through the power switch. All circuit control modules are powered by a 220V AC to 24V 14A switching power supply 9.

[0040] As Figures 1-5 shown, in this embodiment, a signal collector 6 is arranged at a corner of the fixing plate 11 for collecting and outputting signals.

[0041] Exemplarily, the signal collector 6 is a 48-channel digital signal acquisition module with Modbus communication function. After the output signal of the aging product is connected to the acquisition module, the data is transmitted to the display screen 8 through Modbus communication for real-time display and dynamic aging counting. The test status and cycle count of each aging product are displayed on the display screen 8 in real time. For products on different layers, they can be viewed by clicking the touch button. After a batch of products is aged, the count can be cleared.

[0042] As Figures 1-5 shown, in this embodiment, a time relay 7 is provided at one end of the product fixing device 2 for cyclically turning on and off (2s) the power supply test circuit.

[0043] Working principle: To ensure the reliable function of the inductive proximity sensor, each product needs to be powered on and aged after production, and during the aging period, the load and dynamic output are cyclically switched. In addition to the inductive proximity sensor, it can also be flexibly extended to the aging of other types of sensors (such as speed sensors).

[0044] During the test, connect the cable of the product to be aged to the three corresponding card seats of power supply, ground, and output of the circuit control device 4, and then install the product on the fixed seat 23 through the elastic telescopic clip 22; supply power through the circuit control device 4. The induction block 5 on the guide rail 31 of the moving device 3 corresponds to each product. When the motor 32 drives the guide rail 31 to perform telescopic reciprocating motion through the cam 33, it drives the induction block 5 to cyclically switch between the induction and non-induction states with the product. The high and low levels of the product output port are alternately output, and the output signal is sampled by the signal collector 6 for digital quantity, and then the sampled signal is connected to the display screen 8 through Modbus communication to display the real-time status and dynamic count of the aging product; the staff only needs to check the status and count of the product in the display screen 8, and take out the corresponding product if any abnormality is found.

[0045] Through the above technical solutions, the present application can age different categories or batches of products in layers, simulate the actual working environment of the products, perform load dynamic aging tests, effectively improve the product reliability and test efficiency, and monitor and count the product output status in real time, effectively reducing the labor cost.

[0046] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
