[0002] With the development of electronic sensing technology, laser ranging and image processing technology, modern warp testers have gradually integrated high-precision displacement sensors, non-contact laser scanning modules and real-time data processing systems. They can quickly capture micron-level deformation and automatically analyze warp curves and parameters through software. They are widely used in semiconductor, PCB, composite material and other fields to improve product quality and process optimization efficiency.

[0003] A warpage tester disclosed in Chinese patent CN210036678U includes a control box, a worktable, and a distance sensor. The worktable is mounted on the control box and is used to place materials. The distance sensor is slidably mounted on the worktable and is used to slide relative to the worktable under the control of the control box to measure the distance between itself and various points on the material.

[0004] The existing warpage tester described above fixes the distance sensor to a slider, which is then slidably mounted on a guide rail bracket, allowing the distance sensor to move along the guide rail to adjust its detection position. However, this method of installing the distance sensor has the following drawbacks: First, the sensor and slider are fixedly connected, requiring tools for assembly and disassembly, making the process cumbersome; second, it lacks a quick positioning structure, necessitating repeated calibration of the reference position after reinstallation, thus affecting efficiency.

[0005] To address the aforementioned problems, this utility model proposes a warpage tester that is easy to install and position. Utility Model Content

A limiting groove 21 is opened on the bottom side of the connecting post 5. The limiting rod 20 is inserted and engaged with the limiting groove 21.

[0029] A distance measuring sensor 6 is fixedly installed at the end of the connecting column 5 that is away from the fixed column 3.

[0030] In this embodiment of the invention: a placement rack 7 is fixedly installed on the inner bottom surface of the fixing frame 1, and an anti-slip groove 8 is provided on the upper surface of the placement rack 7. The placement rack 7 provides a stable support surface, and the anti-slip groove 8 prevents the object being tested from sliding, ensuring the accuracy of the test.

[0031] In this embodiment of the utility model: the inner wall of the fixing frame 1 is provided with side sliding grooves 9 on both sides, and a movable plate 10 is slidably installed inside the two side sliding grooves 9. A T-shaped sliding groove 11 is provided on the lower end surface of the movable plate 10, and a T-shaped slider 12 is slidably installed inside the T-shaped sliding groove 11. The bottom end of the T-shaped slider 12 is fixedly connected to the fixing post 3.

[0032] In this embodiment of the utility model: a fixing plate 22 is fixedly installed at one end of the limiting rod 20 away from the irregular block 17, a pull ring 23 is fixedly installed on the lower end face of the fixing plate 22, and a second spring 24 is fixedly connected to both sides of the upper end face of the fixing plate 22. The other end of the second spring 24 is fixedly connected to the outer wall of the fixing column 3. This facilitates manual operation of the limiting rod 20, and the second spring 24 provides a stable restoring force.

[0033] In this embodiment of the invention: rectangular sliding grooves 25 are provided on both sides of the inner side of the sliding groove 4, and rectangular sliders 26 are fixedly installed on both sides of the connecting post 5 and the irregular block 17. The rectangular sliders 26 slide in cooperation with the rectangular sliding grooves 25. The rectangular guide structure ensures accurate positioning when the connecting post 5 is inserted, preventing skewing.

[0034] Working principle:

[0035] When installing the ranging sensor 6, the operator must accurately align the mounting end of the connecting post 5 with the entrance of the slide groove 4. Guided by the cooperation of the rectangular slide groove 25 and the rectangular slider 26, ensure that the limiting groove 21 on the connecting post 5 maintains a vertically downward orientation and smoothly slides into the slide groove 4. During this installation process, the front end face of the connecting post 5 contacts the irregularly shaped block 17 and applies a pushing force, forcing the irregularly shaped block 17 to slide smoothly along the inner wall of the slide groove 4. This action simultaneously causes the first spring 18 to undergo uniform compression deformation. The movement of the irregularly shaped block 17, through the cooperation of its inclined groove 19 and the inclined surface of the limiting rod 20, precisely guides the limiting rod 20 to move downwards in the vertical direction, allowing the limiting rod 20 to completely exit the internal space of the slide groove 4. At this time, the second spring 24, having lost its restraint, elastically elongates. When the connecting post 5 continues to move downward until its limiting groove 21 is accurately aligned with the installation position of the limiting rod 20, the restoring force of the second spring 24 is transmitted through the fixing plate 22, pushing the limiting rod 20 into the limiting groove 21 to form a reliable mechanical lock, thereby completing the quick installation and fixing of the ranging sensor 6. During disassembly, the operator needs to apply vertical downward force to the pull ring 23, which drives the limiting rod 20 to move downward against the elastic force of the second spring 24 through the fixing plate 22, so that the limiting rod 20 is completely freed from the constraint of the limiting groove 21. At this time, the restoring force of the first spring 18 pushes the irregular block 17 to slide outward, thereby smoothly pushing the connecting post 5 out of the slide groove 4, realizing the safe disassembly of the ranging sensor 6.

[0036] During position adjustment, the starter motor 16 drives the screw 15 to rotate, which in turn drives the connecting block 14 to make precise lateral linear movement along the guide groove 13 through threaded transmission, thereby causing the electric telescopic rod 2 and the distance sensor 6 to move laterally as a whole. Simultaneously, by controlling the extension or retraction of the telescopic end of the electric telescopic rod 2, the fixed column 3 and the distance sensor 6 are adjusted longitudinally. The T-shaped slide groove 11 on the moving plate 10 and the T-shaped slider 12 at the bottom of the fixed column 3 form a precise fit, ensuring that the fixed column 3 maintains a stable trajectory during movement and effectively preventing deviation or swaying. This adjustment mechanism, through the coordinated work of the motor 16 and the electric telescopic rod 2, can achieve precise positioning of the distance sensor 6 in both horizontal and vertical directions, meeting the needs of different measurement scenarios.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
