Detailed Implementation

[0022] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0023] Reference Figure 1 and Figure 2 The present invention provides a probe aging test device, including a base 100, a fixed plate 110, a movable plate 120, a spring tester 130, and a drive assembly 140. The spring tester 130 and the drive assembly 140 are fixed on the base 100. The fixed plate 110 is connected to the input end of the spring tester 130. The fixed plate 110 and the movable plate 120 are arranged opposite to each other. The probe to be tested is installed on the fixed plate 110 or the movable plate 120. The drive assembly 140 is used to drive the movable plate 120 to move closer to or away from the fixed plate 110 to press or release the probe to be tested.

[0024] Understandably, by driving the movable plate 120 to reciprocate through the drive component 140, the probe can be automatically and repeatedly pressed or released. The spring tester 130 can monitor the pressure state of the probe in real time, which facilitates timely adjustment of the probe compression and ensures the stability of the probe compression. Thus, automatic testing can be achieved, reducing manual labor intensity, saving labor costs, and improving testing efficiency and accuracy.

[0025] In some preferred embodiments, the base 100 is horizontally arranged, and the fixed plate 110 and the movable plate 120 are both vertically arranged, which facilitates the mounting of the probe to be tested on the fixed plate 110 or the movable plate 120.

[0026] Specifically, the probe to be tested is mounted on the fixed plate 110 or the movable plate 120 by means of a probe fixing device.

[0027] Furthermore, a guide rail 150 is provided on the base 100, and a slider 160 is connected to the movable plate 120. The slider 160 is slidably connected to the guide rail 150. When the drive assembly 140 drives the movable plate 120 to move back and forth, the movable plate 120 drives the slider 160 to slide along the guide rail 150, thereby avoiding probe deviation during the test and improving the stability of the test.

[0028] Furthermore, the drive assembly 140 includes a servo motor 170, a lead screw 180 disposed on the output shaft of the servo motor 170, a lead screw nut 190 threadedly connected to the lead screw 180, and a translation seat 200 connected to the lead screw nut 190. The servo motor 170 is mounted on the base 100, the lead screw 180 is connected to the base 100 through two bearing seats 210, the movable plate 120 is connected to the top of the translation seat 200, the slider 160 is connected to the bottom of the translation seat 200, and the length direction of the lead screw 180 extends along the length direction of the guide rail 150.

[0029] It is understandable that by driving the lead screw 180 to rotate through the servo motor 170, the lead screw 180 drives the lead screw nut 190, the translation seat 200 and the movable plate 120 to move together. By controlling the speed of the servo motor 170, precise position control and speed adjustment can be achieved, thereby ensuring the accuracy of the probe aging test.

[0030] In some preferred embodiments, a sensing plate 220 is provided on one side of the translation seat 200, and two slotted photoelectric sensors 230 are provided on the base 100. The two slotted photoelectric sensors 230 are located at the start position and the end position of the translation seat 200, respectively, and the groove of the slotted photoelectric sensor 230 is used to accommodate the sensing plate 220.

[0031] When the servo motor 170 drives the translation seat 200 to move, the translation seat 200 moves the sensing plate 220 into the groove of one of the slotted photoelectric sensors 230 and triggers a signal feedback to the servo motor 170. The servo motor 170 stops, causing the movable plate 120 on the translation seat 200 to stay at the starting or ending position. This ensures the displacement accuracy of the movable plate 120, realizes closed-loop control of the movement stroke of the movable plate 120, avoids overshoot or incomplete positioning caused by transmission errors, prevents the probe from being damaged by overpressure or the movable plate 120 from colliding with the fixed plate 110, and improves the safety performance of the equipment.

[0032] Reference Figure 2 and Figure 3 Furthermore, the base 100 is also provided with a strip block 240, and two T-shaped grooves 250 are provided in the strip block 240. The length direction of the T-shaped grooves 250 extends along the length direction of the guide rail 150. The T-shaped grooves 250 are used to clamp the head of the bolt. The slotted photoelectric sensor 230 is provided with two mounting holes 260. The diameter of the mounting holes 260 is larger than the diameter of the bolt shank and smaller than the diameter of the bolt head. The two slotted photoelectric sensors 230 are fixed to the strip block 240 by bolts and nuts.

[0033] Understandably, during installation, the bolt head is first engaged in the T-shaped groove 250, and the bolt is moved along the length of the T-shaped groove 250 to the installation position of the slot-shaped photoelectric sensor 230. Then, the mounting hole 260 on the slot-shaped photoelectric sensor 230 is aligned with the bolt, and the bolt passes through the mounting hole 260. Finally, the nut is tightened on the bolt to lock the bolt head in the T-shaped groove 250, and the slot-shaped photoelectric sensor 230 is fixed on the strip block 240.

[0034] When the position of the slotted photoelectric sensor 230 needs to be adjusted, simply loosen the nut to disengage the bolt head from the T-shaped slide 250. Then, move the bolt along the length of the T-shaped slide 250 to move the slotted photoelectric sensor 230 to the desired position. Finally, tighten the nut to fix the slotted photoelectric sensor 230 in the desired position on the strip block 240. This allows for quick adjustment of the installation position of the slotted photoelectric sensor 230.

[0035] Furthermore, the sensing element 220 is fixed to one side of the translation seat 200 by bolts. The translation seat 200 is provided with a threaded hole 270, and the sensing element 220 is provided with a waist-shaped hole 280. The length direction of the waist-shaped hole 280 is vertical, and the width of the waist-shaped hole 280 is greater than the diameter of the bolt shank and less than the diameter of the bolt head, thereby facilitating the adjustment of the height position of the sensing element 220.

[0036] In some preferred embodiments, a coupling 290 is connected between the output shaft of the servo motor 170 and the lead screw 180 to facilitate the connection between the servo motor 170 and the lead screw 180, which can reduce intermediate transmission errors and further improve the displacement accuracy of the movable plate 120, thereby ensuring the accuracy of the probe aging test.

[0037] This utility model embodiment also provides a testing machine, including a housing, a control system, a storage system and the above-mentioned probe aging test device disposed in the housing. The control system is used to control the operation of the drive component 140, the storage system is used to store test data, and the spring tester 130 uploads the test data to the storage system and automatically generates a data table for recording, thereby facilitating the analysis of the test results.

[0038] Furthermore, an external impedance tester can be connected. The impedance tester is connected to a test clip via a wire. The test clip is held on the probe to facilitate reading the resistance value of the probe, and the measured resistance data is uploaded to the storage system and automatically generated into a data table for recording.

[0039] Furthermore, the top of the housing is equipped with a flip cover. When the flip cover is open, it is convenient to put in and take out the probe under test. During the test, closing the flip cover can protect the internal equipment, prevent foreign objects from entering the housing and affecting the test process, and also prevent the probe from accidentally popping out during the test.

[0040] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
