Description

Technical Field

[0001] This utility model relates to the field of probe technology, and in particular to a multifunctional probe testing machine. Background Technology

[0002] Traditional functional tests, such as elasticity, resistance, and compression life tests, often rely on single-function devices with cumbersome procedures, requiring significant time and manpower. This device integrates elasticity, resistance, and life testing into a single unit. It allows for the use of any single function or a combination of all three. The setup process is streamlined and entirely software-controlled, greatly improving the accuracy and reliability of parameter settings. In principle, it saves a substantial amount of time compared to traditional testing procedures. Furthermore, the mature technology and high-quality components ensure reliable and traceable test results, further guaranteeing accuracy. Test data and curves can be exported and saved, offering high ease of use. There are many devices on the market for testing resistance, elasticity, and lifespan, but they are relatively simple and have limited functions. Changing the testing function requires changing the device, which consumes a lot of time and resources. While there may be similar devices (combining elasticity, resistance, and other functions into one or three), their technology and testing accuracy still need to be verified. Existing technologies are costly in terms of manpower, time, and expenses, have cumbersome setup steps, complex processes, and are limited by certain usage environments.

[0003] Chinese patent CN211926936U discloses a multifunctional probe integrated testing machine that facilitates multi-attribute testing of probes. The machine includes a housing, a Z-axis motor, an X-axis motor, and a Y-axis motor. A Z-axis guide rod is fixedly installed inside the housing. A first cantilever beam and a second cantilever beam are fixedly mounted on the Z-axis guide rod. A first load cell and a second load cell are fixedly connected to the outer walls of the first and second cantilever beams, respectively. An insulating column is fixedly connected to the bottom of the second load cell, and a test head is fixedly mounted at the lower end of the insulating column. The X-axis motor is fixed to a base plate, which is installed at the bottom of the housing.

[0004] However, the load cell in this technical solution is susceptible to electromagnetic interference, resulting in unstable signal transmission and affecting the detection results. Furthermore, the structure of the cantilever beam with Z-axis guide rod experiences significant wear during use, leading to instability and potential wobbling. Consequently, the load cell becomes unstable, resulting in large measurement errors. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a multifunctional probe testing machine. This machine uses an elastic force sensing component to detect the elastic force of the probe, which avoids electromagnetic interference and ensures the accuracy of the test results. Combined with a resistance measuring instrument, it can quickly detect the resistance value of the probe, resulting in high working efficiency. Furthermore, the ball screw mechanism has a sufficiently stable structure, preventing the elastic force sensing component mounted on it from easily moving, thus ensuring good stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multifunctional probe testing machine includes: a base, an X-axis moving platform disposed on the base, a Y-axis moving platform slidably connected to the X-axis moving platform, a testing platform slidably connected to the Y-axis moving platform, a support seat disposed on one side of the X-axis moving platform, a lifting assembly disposed on the support seat and facing the X-axis moving platform, an elastic force sensing assembly disposed on the lifting assembly and moving together with the lifting assembly, and a resistance measuring instrument disposed on one side of the elastic force sensing assembly.

[0011] Preferably, the connecting assembly includes: a connecting plate vertically fixed to the movable block, a mounting plate horizontally disposed in the middle of the connecting plate, and a plurality of reinforcing ribs disposed between the connecting plate and the mounting plate.

[0012] Preferably, the test platform includes: a fixed base plate fixedly connected to the test plate, a brass base disposed on the fixed base plate, and a probe test holder disposed on the brass base.

[0013] Preferably, the first slide rail and the fixed base, as well as the second slide rail and the test plate, are connected by a number of sliders.

[0014] Preferably, the support base is provided with an opening that matches the height of the test platform.

[0015] Preferably, the support base and the base are fixedly connected by several vertical plates.

[0016] The beneficial effects of this utility model are as follows: (1) This utility model integrates the three functions of testing the probe's elasticity, resistance, and lifespan by repeatedly testing the probe with an elasticity sensor, a resistance measuring instrument, and a ball screw mechanism. This reduces a lot of manual operation, has a high degree of automation, improves work efficiency, and the elasticity sensor is not affected by electromagnetic fields, which can ensure the accuracy of the test results.

[0017] (2) This utility model uses a ball screw mechanism to precisely control the up-and-down reciprocating movement of the elastic sensor, which converts the rotation of the shaft into linear motion. It is easy to control, has high precision, better stability, and will not easily shake, thereby reducing the measurement error of the elastic sensor component and ensuring the accuracy of the measurement results.

[0018] In summary, this utility model has the advantages of multi-functional integration, high degree of automation, high work efficiency, accurate detection results, and small error. Attached Figure Description

[0022] Example like Figures 1-3 As shown, this embodiment provides a multifunctional probe testing machine, including: a base 1, an X-axis moving platform 2 disposed on the base 1, a Y-axis moving platform 3 slidably connected to the X-axis moving platform 2, a testing platform 4 slidably connected to the Y-axis moving platform 3, a support base 5 disposed on one side of the X-axis moving platform 2, a lifting assembly 6 disposed on the support base 5 and facing the X-axis moving platform 2, an elastic force sensing assembly 7 disposed on the lifting assembly 6 and moving together with the lifting assembly 6, and a resistance measuring instrument 8 disposed on one side of the elastic force sensing assembly 7. The elastic force sensing assembly 7 is used to test the elasticity of the probe, the resistance measuring instrument 8 is used to detect the resistance of the probe, and the lifespan of the probe can be detected by the number of times it is pressed down. The three components have clear division of labor, reducing a lot of manual operation, with a high degree of automation and improved testing efficiency.

[0023] The elasticity sensing component 7 includes an elasticity sensor 71 and a force display 72 disposed on one side of the elasticity sensor 71. The resistance measuring instrument 8 is connected to the force display 72 to ensure measurement accuracy, thereby ensuring the quality of the probe.

[0024] Meanwhile, the X-axis moving platform 2 includes: a receiving plate 21 fixedly connected to the end face of the base 1 and a plurality of first slide rails 22 disposed on the receiving plate 21 and adapted to the Y-axis moving platform 3, so that the entire test platform 4 can move on the X-axis to detect probes at different positions.

[0025] In this embodiment, the receiving plate 21 and the base 1 can be fixedly connected by multiple pins to prevent the position of the receiving plate 21 from shifting.

[0026] In this embodiment, the Y-axis moving platform 3 includes: a fixed base 31 slidably connected to the first slide rail 22, a plurality of second slide rails 32 disposed on the fixed base 31, and a test plate 33 slidably connected to the second slide rails 32 and used to support the test platform 4, so that the entire test platform 4 can move on the Y-axis to detect probes at different positions, which is highly flexible.

[0027] In this embodiment, the sliding of the fixed base 31 and the test plate 33 can be driven by a cylinder, which has a fast response speed. After one probe has finished testing, the next probe can be tested at any time. The process is simple to operate, convenient to use, and can ensure testing efficiency.

[0028] In this embodiment, limit blocks 35 are provided at both ends of the first slide rail 22 and the second slide rail 32 to prevent the fixed seat 31 and the test plate 33 from sliding out of the corresponding slide rail, so that the two slide within a limited range.

[0029] In this embodiment, the lifting assembly 6 includes: a ball screw mechanism 61 vertically mounted on the side wall of the support base 5; a receiving block 62 mounted at the bottom of the ball screw mechanism 61; a driving component 63 mounted at the top of the ball screw mechanism 61 for driving the ball screw mechanism 61 to run; and a connecting component 64 mounted on the moving block of the ball screw mechanism 61 and fixedly connected to the elastic sensing assembly 7. The driving component 63 is preferably a servo motor, used in conjunction with an encoder and a coupling, to provide maximum power for the up-and-down reciprocating movement of the elastic sensing assembly 7. The ball screw mechanism 61 converts rotation into linear motion, which is convenient to control and has high precision, and can reduce the measurement error of the elastic sensing assembly 7. The connecting component 64 can ensure the stability of the elastic sensing assembly 7 when it moves, and avoid large-amplitude shaking when it moves up and down.

[0030] In this embodiment, the connecting component 64 includes: a connecting plate 641 vertically fixedly connected to the moving block, a mounting plate 642 horizontally disposed in the middle of the connecting plate 641, and a plurality of reinforcing ribs 643 disposed between the connecting plate 641 and the mounting plate 642, which further ensures the stability of the elastic sensing component 7 when it moves, avoids its positional deviation, and ensures the accuracy of the measurement results; the reinforcing ribs 643 can ensure the stability and firmness of the entire connecting component 64, thereby extending the service life of the connecting component 64.

[0031] In this embodiment, the elastic sensor 71 is mounted on the mounting plate 642 and externally connected to the force display 72.

[0032] In this embodiment, the test platform 4 includes: a fixed base plate 41 fixedly connected to the test plate 33, a brass base 42 disposed on the fixed base plate 41, and a probe test seat 43 disposed on the brass base 42. The fixed base plate 41 is generally made of Peek sheet material, which is insulating and will not scratch the probe, thus ensuring the integrity of the probe. The brass base 42 has good machinability and can be quickly milled with high-density array pin holes, making it easy to replace and low in cost. The probe test seat 43 (usually with spring clips) can ensure that each probe being tested is in uniform 360° contact with the internal brass hole wall to reduce errors.

[0033] In this embodiment, the first slide rail 22 and the fixed base 31, as well as the second slide rail 32 and the test plate 33, are connected by a number of sliders 34. The sliders 34 can prevent the fixed base 31 and the test plate 33 from directly rubbing against their corresponding slide rails, thereby reducing wear and ensuring service life. In addition, the first slide rail 22 and the second slide rail 32 are both linear.

[0034] In this embodiment, the support base 5 is provided with an opening 51 that matches the height of the test platform 4 to avoid interference between the two, so that each probe on the test platform 4 can be detected.

[0035] In this embodiment, the support base 5 and the base 1 are fixedly connected by several vertical plates 52, which ensures the stability between the two and makes the structure more robust, thereby ensuring the smooth progress of the testing work.

[0036] In this embodiment, the resistance measuring instrument 8 is connected to the force display 72 via a 485 communication line. One end of the test port of the resistance measuring instrument 8 is connected to the brass base 42 of the test platform 4, and the other end is connected to the test fixture. Specifically, the connection can be fixed by bolts. The test fixture can be gripped by a robotic arm or manual tweezers.

[0037] In this embodiment, the test page of the force display 72 software is arranged according to the process, the page is clear and easy to understand, and the steps are performed one by one with clear hierarchy; it can also set the pressing distance, calibrate the number of movements, adjust the motor speed, etc., and display the current position of the test head and the target position in real time.

[0038] In this embodiment, the steps set by the testing machine can be saved and reused, and the testing process does not require manual intervention, which greatly saves manpower and testing costs. Moreover, the process is efficient, the setting functions and testing speed are optional, the application is wide-ranging, the process is simple, the functions are comprehensive, and it is easy and convenient to use. The testing machine also integrates resistance, elasticity and life testing functions. The setting steps only need to be done once and can be saved and reused, which greatly reduces the user's operation time and realizes fully automated testing.

[0039] Of course, you can first use anti-static tweezers to pick up the probe, place the probe into the probe test holder 43, and move the test holder directly under the test fixture. Then, move the sensor fixing assembly to touch the probe.

[0040] In this embodiment, the test page of the force display 72 is provided with an operation panel 73, and the specific labeling of the operation panel 73 is as follows: Current position: the bottom surface of the test fixture; Target location: the distance from the reference point to the downward pressure; Set a reference point: that is, take the current position as the starting point (zero point); Remote emergency stop: Controls the servo motor to stop working; Number of exercises: You can set the number of tests; Current number of exercises: Displays the total number of tests performed; Manual speed: Allows control of the servo motor's downward pressing speed; Reset: Return to the starting point.

[0041] Additionally, assuming the probe's travel distance is 5.5mm, set the current position as the reference point on the test page, the downward pressure distance as -5.0mm, the number of movements as 100,000, and the speed as 100%. Click "Auto Start." On the test page, the probe's resistance increases as the downward pressure travels and decreases as it travels upwards; the probe's elasticity also increases as the downward pressure travels and decreases as it travels upwards. The tester should observe the changes in resistance and elasticity after 10,000, 30,000, 50,000, 80,000, and 100,000 probe presses and compare them with the previous results. The normal probe lifespan is around 200,000 cycles, while some high-end test probes can reach around 500,000 cycles.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
