Description

Technical Field

[0001] This utility model relates to the field of semiconductor testing technology, specifically a spring probe extension and retraction detection device. Background Technology

[0002] Spring probes are electronic connection components widely used in electronic testing, charging connections, and precision instruments. Their core function is to achieve stable electrical contact through the elastic action of a spring. They typically consist of a needle tip, spring, needle tube, and tail connection structure, and are characterized by high precision, wear resistance, and vibration resistance, enabling reliable signal transmission or power conduction within confined spaces.

[0003] In the existing technology, the extension and retraction detection of spring probes is often carried out manually by pulling the probe. When the probe is stretched to its limit, the length of the probe after stretching is measured by a measuring instrument.

[0004] There are still some shortcomings in the existing technology. When the manual stretching probe moves, the stretching distance cannot be measured in real time during the measurement process, which can easily cause certain errors in the detection process and affect the accuracy of the detection process. Therefore, we propose a spring probe telescopic detection device. Utility Model Content

[0005] The purpose of this invention is to provide a spring probe telescopic detection device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spring probe telescopic detection device, including a mounting plate; The tail block is positioned above the mounting plate; A needle tube is fixedly connected to the top of the tail block; A spring is fixedly connected to the bottom of the inner wall of the needle tube; The other end of the spring is fixedly connected to a limit block; A probe is fixedly connected to the top of the limiting block; And a tensioning assembly disposed on the top of the mounting plate, the tensioning assembly including a support platform fixedly connected to the center of the top of the mounting plate, the bottom of the inner wall of the support platform being slidably connected to the bottom of the tail block, a first U-shaped frame fixedly connected to the top left side of the support platform, a T-shaped groove formed on the inner side wall of the first U-shaped frame, a drive motor fixedly connected to the center of the top of the first U-shaped frame, a lead screw fixedly connected to the output end of the drive motor, the bottom outer wall of the lead screw being rotatably connected to the bottom of the inner wall of the first U-shaped frame via a bearing, a sleeve block being threadedly connected to the outer wall of the lead screw, a T-shaped block being fixedly connected to the left side of the sleeve block, the left end outer wall of the T-shaped block being slidably connected to the inner wall of the T-shaped groove, the sleeve... A connecting block is fixedly connected to the right side of the connecting block, and a rectangular frame is fixedly connected to the right end of the connecting block. An electric push rod is fixedly connected to the inner wall of the rectangular frame, and a positioning block is fixedly connected to the output end of the electric push rod. The inner wall of the positioning block is slidably connected to the top outer wall of the probe. By setting up a tensioning component, the operator can turn on the drive motor to make the lead screw rotate. When the lead screw rotates, after the T-slot and T-block limit the connection block, it will cause the connection block to move upward along the outer wall of the lead screw. When the connection block moves upward, it will pull the rectangular frame upward through the connecting block. When the rectangular frame moves upward, it can drive the probe to stretch upward, thereby realizing the telescopic detection of the probe.

[0007] Preferably, the stretching assembly further includes an indicator block fixedly connected to the right side of the rectangular frame. A scale is slidably connected to the inner wall of the other end of the indicator block. A second U-shaped frame is fixedly connected to the top of the scale. The bottom left side of the second U-shaped frame is fixedly connected to the top right side of the support platform. When the rectangular frame stretches the probe upward, it will drive the indicator block to move upward along the outer wall of the scale. The value on the scale surface corresponding to the indicator block is the extension length of the probe, thereby realizing the extension detection process.

[0008] Preferably, the support platform is further provided with a fixing component. The fixing component includes a screw threaded to the inner wall of the front of the support platform. An adjusting block is fixedly connected to the outer wall of one end of the screw, and a clamping plate is rotatably connected to the other end of the screw. One side of the clamping plate is slidably connected to the outer wall of the tail block, and a limiting rod is fixedly connected to the other side of the clamping plate. The outer wall of the limiting rod is slidably connected to the inner wall of the front of the support platform. By setting up the fixing component, when the operator places the tail block inside the support platform and needs to fix the tail block, the operator rotates the two adjusting blocks to make the screw rotate. During the rotation of the screw, the clamping plate is limited by the limiting rod, which will cause the clamping plate to move until the two clamping plates squeeze the two sides of the tail block, thereby fixing the tail block and improving the stability during the detection process.

[0009] Preferably, the bottom of the mounting plate is fixedly connected with four support legs. The four support legs are equidistantly fixed at the bottom of the four corners of the mounting plate, so that the mounting plate can be stably supported by the four support legs at the bottom of the mounting plate.

[0010] Preferably, there are two positioning blocks, which are symmetrically distributed along the center plane of the rectangular frame.

[0011] Preferably, there are two clamping plates, which are located on the front and rear sides of the bottom of the tail block.

This spring probe extension / retraction detection device has the following advantages: (1) The spring probe telescopic detection device, by setting a tension component, when it is necessary to perform telescopic detection on the probe, firstly, the operator places the tail block inside the mounting plate and fixes the tail block. Then, the operator puts the probe inside the rectangular frame. Then, by turning on the electric push rod inside the rectangular frame, the output end of the electric push rod is extended and the two positioning blocks are pushed to move towards the top outer wall of the probe to fix the probe and improve the stability during the telescopic detection of the probe. Then, the operator turns on the drive motor to make the lead screw rotate. When the lead screw rotates, after the T-slot and T-block limit the socket block, the socket block will move upward along the outer wall of the lead screw. When the socket block moves upward, the rectangular frame will be pulled upward by the connecting block. When the rectangular frame moves upward, the probe can be stretched upward, thereby realizing the telescopic detection of the probe. (2) The spring probe telescopic detection device, by setting a fixing component, when the operator places the tail block inside the bearing platform and needs to fix the tail block, the operator rotates two adjusting blocks to make the screw rotate. When the screw rotates, the clamping plate is limited by the limiting rod, which will cause the clamping plate to move until the two clamping plates squeeze the two sides of the tail block, thereby fixing the tail block and improving the stability of the detection process.

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0016] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0017] Example 1 A spring probe telescopic detection device includes a mounting plate 1; Tail block 3 is positioned above mounting plate 1; A needle tube 5 is fixedly connected to the top of the tail block 3; A spring 6 is fixedly connected to the bottom of the inner wall of the syringe 5; The other end of spring 6 is fixedly connected to limit block 7; A probe 8 is fixedly connected to the top of the limiting block 7; And a tensioning assembly 41 is provided on the top of the mounting plate 1. The tensioning assembly 41 includes a support platform 411 fixedly connected to the center of the top of the mounting plate 1. The bottom of the inner wall of the support platform 411 is slidably connected to the bottom of the tail block 3. A first U-shaped frame 412 is fixedly connected to the top left side of the support platform 411. A T-shaped groove 413 is opened on the inner side wall of the first U-shaped frame 412. A drive motor 414 is fixedly connected to the center of the top of the first U-shaped frame 412. A lead screw 415 is fixedly connected to the output end of the drive motor 414. The bottom outer wall of the lead screw 415 is connected to the first U-shaped frame 412 through a bearing. The bottom of the inner wall is rotatably connected, and the outer wall of the lead screw 415 is threadedly connected to the sleeve block 416. The left side of the sleeve block 416 is fixedly connected to the T-shaped block 417. The outer wall of the left end of the T-shaped block 417 is slidably connected to the inner wall of the T-shaped groove 413. The right side of the sleeve block 416 is fixedly connected to the connecting block 418. The right end of the connecting block 418 is fixedly connected to the rectangular frame 419. The inner wall of the rectangular frame 419 is fixedly connected to the electric push rod 4110. The output end of the electric push rod 4110 is fixedly connected to the positioning block 4111. The inner wall of the positioning block 4111 is slidably connected to the top outer wall of the probe 8. By setting the tension assembly 41, during the process of performing a tension test on the probe 8, the operator first places the tail block 3 inside the mounting plate 1 and fixes it. Then, the operator places the probe 8 inside the rectangular frame 419. Subsequently, by activating the electric push rod 4110 inside the rectangular frame 419, the output end of the electric push rod 4110 extends, pushing the two positioning blocks 4111 towards the top outer wall of the probe 8, thereby fixing the probe 8 and improving the tension test process. To ensure stability, the operator then turns on the drive motor 414, causing the lead screw 415 to rotate. As the lead screw 415 rotates, the T-slot 413 and T-block 417 limit the socket block 416, causing the socket block 416 to move upward along the outer wall of the lead screw 415. As the socket block 416 moves upward, the connecting block 418 pulls the rectangular frame 419 upward. As the rectangular frame 419 moves upward, it can drive the probe 8 to stretch upward, thereby realizing the extension and retraction detection of the probe 8. The stretching assembly 41 also includes an indicator block 4114 fixedly connected to the right side of the rectangular frame 419. A scale 4113 is slidably connected to the inner wall of the other end of the indicator block 4114. A second U-shaped frame 4112 is fixedly connected to the top of the scale 4113. The bottom left side of the second U-shaped frame 4112 is fixedly connected to the top right side of the support platform 411. When the rectangular frame 419 stretches the probe 8 upward, it will drive the indicator block 4114 to move upward along the outer wall of the scale 4113. The value on the surface of the scale 4113 corresponding to the indicator block 4114 is the extension length of the probe 8, thereby realizing the extension detection process. The bottom of the mounting plate 1 is fixedly connected with four support legs 2. The four support legs 2 are fixedly connected at equal intervals at the bottom of the four corners of the mounting plate 1. The four support legs 2 at the bottom of the mounting plate 1 can provide stable support for the mounting plate 1. There are two positioning blocks 4111, and the two positioning blocks 4111 are symmetrically distributed along the center face of the rectangle 419.

[0018] Example 2 The difference from Embodiment 1 is that this embodiment discloses a fixing component, such as... Figure 5 As shown: The support platform 411 is also equipped with a fixing component 42. The fixing component 42 includes a screw 421 threadedly connected to the inner wall of the front of the support platform 411. An adjusting block 422 is fixedly connected to the outer wall of one end of the screw 421, and a clamping plate 423 is rotatably connected to the other end of the screw 421. One side of the clamping plate 423 is slidably connected to the outer wall of the tail block 3, and a limit rod 424 is fixedly connected to the other side of the clamping plate 423. The outer wall of the limit rod 424 is slidably connected to the inner wall of the front of the support platform 411. When the operator places the tail block 3 inside the support platform 411 and needs to fix the tail block 3, the operator rotates the two adjusting blocks 422 to cause the screw 421 to rotate. During the rotation of the screw 421, the clamping plate 423 is limited by the limiting rod 424, which causes the clamping plate 423 to move until the two clamping plates 423 press against both sides of the tail block 3, thereby fixing the tail block 3 and improving the stability during the detection process. There are two clamping plates 423, which are located on the front and back sides of the bottom of the tail block 3.

[0019] Working principle: During the extension and retraction test of probe 8, the operator first places the tail block 3 inside the mounting plate 1 and fixes it. Then, the operator places probe 8 inside the rectangular frame 419. Subsequently, by activating the electric push rod 4110 inside the rectangular frame 419, the output end of the electric push rod 4110 extends, pushing the two positioning blocks 4111 towards the top outer wall of probe 8, thereby fixing probe 8 and improving the stability during the extension and retraction test of probe 8. Subsequently, the operator turns on the drive motor 414 to make the lead screw 415 rotate. When the lead screw 415 rotates, the T-slot 413 and the T-block 417 limit the socket block 416, which will cause the socket block 416 to move upward along the outer wall of the lead screw 415. When the socket block 416 moves upward, it will pull the rectangular frame 419 upward through the connecting block 418. When the rectangular frame 419 moves upward, it can drive the probe 8 to stretch upward, thereby realizing the extension and retraction detection of the probe 8. When the rectangular frame 419 stretches the probe 8 upward, it will cause the indicator block 4114 to move upward along the outer wall of the scale 4113. The value on the surface of the scale 4113 corresponding to the indicator block 4114 is the extension length of the probe 8, thereby realizing the extension detection process. When the operator places the tail block 3 inside the support platform 411 and needs to fix the tail block 3, the operator rotates the two adjusting blocks 422 to cause the screw 421 to rotate. During the rotation of the screw 421, the clamping plate 423 is limited by the limiting rod 424, which causes the clamping plate 423 to move until the two clamping plates 423 press against both sides of the tail block 3, thereby fixing the tail block 3 and improving the stability during the testing process.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above.
