Although specific embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0020] It should be noted that certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that technicians may use different nouns to refer to the same component. This specification and claims do not use the difference in nouns as a way to distinguish components, but use the difference in the functions of the components as the criterion for distinction. As mentioned throughout the specification and claims, "including" or "comprising" is an open term, so it should be interpreted as "including but not limited to". The subsequent description of the specification is a preferred embodiment of the present disclosure, but the description is based on the general principles of the specification and is not used to limit the scope of the present disclosure. The scope of protection of the present disclosure shall be as defined by the attached claims.

[0021] To facilitate understanding of the embodiments of the present disclosure, further explanation will be given below using specific embodiments as examples in conjunction with the accompanying drawings, and the accompanying drawings do not constitute a limitation on the embodiments of the present disclosure.

[0022] Figures 1 to 3 1 and 2 are respectively a front view, a top view and a rear view of a warpage measuring instrument provided by an exemplary embodiment of the present disclosure, as shown in FIG. Figures 1 to 3 As shown, the warpage measuring instrument includes: a measuring instrument body 1, the measuring instrument body 1 includes a base 2, a first support wall 3 and a second support wall 4 are symmetrically arranged on both sides of the base 2, and the first support wall 3 and the second support wall 4 are integrally formed with the base 2; the base 2 and the first support wall 3 and the second support wall 4 form a measuring slot 5, a feed port 6 is provided on one side of the measuring slot 5, a support platform 7 is provided on the other side of the measuring slot 5, a support frame 8 is provided above the feed port 6, a motor 9 is provided on the support platform 7, and a warpage scanning assembly is provided between the support frame 8 and the motor 9.

[0023] In this embodiment, the warpage scanning assembly is controlled by a motor and does not require human intervention, which can reduce measurement time delays caused by human factors, such as manual positioning, reading, recording and other steps, thereby improving the measurement efficiency of the warpage of objects (for example, plastic products, metal plates, semiconductor wafers, composite products, circuit boards and other precision components); in addition, the warpage scanning assembly is controlled by a motor, which can reduce error sources in human operation, including visual fatigue, inaccurate readings, and improper operation, thereby making the measurement results more stable and reliable.

[0024] In another exemplary embodiment, the warp scanning assembly includes: a screw rod 10, the screw rod 10 is parallel to the measuring slot 5, one end of the screw rod 10 is connected to the motor 9 through a coupling shaft 11, and the other end of the screw rod 10 is connected to the support frame 8 through a connecting hole 12 located in the middle of the support frame 8, and a grating bracket 13 is sleeved on the screw rod 10. Figure 4 As shown, a grating 14 is provided on the side of the grating bracket 13 facing the measuring slot 5 , and the grating 14 slides along the lead screw 10 along with the grating bracket 13 .

[0025] In this embodiment, the lead screw 10 is arranged parallel to the measuring slot 5, allowing the grating bracket 13, which is mounted on the lead screw 10, to slide precisely and smoothly along the lead screw 10. This ensures the stability and accuracy of the grating 14 during the scanning process, thereby improving the accuracy of warpage measurement. Furthermore, because the grating 14 can slide along the measuring slot 5 with the grating bracket 13, it can continuously and dynamically scan the surface of the object under test within the measuring slot 5. This dynamic scanning method can capture subtle deformations and warpage on the object's surface, providing detailed data support for subsequent measurement and analysis.

[0026] In summary, the entire scanning process is driven by a motor, eliminating the need for human intervention and achieving efficient automation. This also improves measurement efficiency and reduces errors introduced by human factors, thereby ensuring the accuracy and consistency of measurement results.

[0027] In another exemplary embodiment, a first slide rail 15 is provided on the first support wall 3 along the direction of the measuring slot 5, and a second slide rail 16 is provided on the second support wall 4 along the direction of the measuring slot 5; a first grating scanning laser sensor 17 is provided on the first slide rail 15, and the first grating scanning laser sensor 17 is connected to one side of the grating bracket 13; a second grating scanning laser sensor 18 is provided on the second slide rail 16, and the second grating scanning laser sensor 18 is connected to the other side of the grating bracket 13; the grating bracket 13 is slidably connected to the first slide rail 15 and the second slide rail 16 through the first grating scanning laser sensor 17 and the second grating scanning laser sensor 18.

[0028] In this embodiment, the dual-slide rail design not only provides guidance for the sliding of the grating bracket 13, but also enhances the overall rigidity of the scanning assembly by supporting both sides simultaneously, which helps to maintain the stability of the measurement system during high-speed or high-precision scanning, thereby improving the reliability and repeatability of the measurement results.

[0029] In another exemplary embodiment, a first laser sensor 19 is provided on the first supporting wall 3 near the support platform 7, a second laser sensor 20 is provided on the first supporting wall 3 near the support frame 8, a third laser sensor 21 is provided on the second supporting wall 4 near the support platform 7, and a fourth laser sensor 22 is provided on the second supporting wall 4 near the support frame 8, wherein the first laser sensor 19 is symmetrically arranged with the third laser sensor 21, and the second laser sensor 20 is symmetrically arranged with the fourth laser sensor 22.

[0030] During the measurement process, this embodiment configures a plurality of laser sensors, and these sensors are symmetrically arranged at different positions of the support wall, so as to accurately detect the position and shape changes of the sample, thereby improving the measurement accuracy.

[0031] In another exemplary embodiment, a plurality of function keys are provided on the support platform 7 on one side of the first support wall 3 .

[0032] In this embodiment, the plurality of function keys include a start key 23 , a pause key 24 and a reset key 25 .

[0033] Below, the present disclosure describes in detail the working principle of the warpage measuring instrument having the above structure:

[0034] First, the object to be tested is placed into the measuring slot 5 through the feed port 6. The operator presses the start button 23, which activates the motor 9 and simultaneously rotates the screw 10 via the coupling shaft. As the screw 10 rotates, the grating bracket 13, which is mounted on the screw 10, moves linearly along it. As the grating bracket 13 moves, the grating 14 also moves along the measuring slot 5, scanning the object to be tested within the slot. Throughout the scanning process, the system generates warpage values, thickness values, and other relevant warpage data in real time.

[0035] Furthermore, because both sides of grating support 13 are connected to first grating scanning laser sensors 17 on first slide rail 15 and second grating scanning laser sensors 18 on second slide rail 16, respectively, the movement of grating support 13 is simultaneously monitored by both second grating scanning laser sensors, thereby ensuring the accuracy and stability of grating scanning. Furthermore, during the scanning process of grating 14, multiple groups of laser sensors (first laser sensor 19, second laser sensor 20, third laser sensor 21, and fourth laser sensor 22) located on first support wall 3 and second support wall 4 assist in positioning grating 14 in real time and monitor the position and posture of the object to be measured in measuring slot 5, thereby improving measurement accuracy.

[0036] After the scan is completed, the measurement can be paused by pressing the pause button 24 on the support table 7, or the motor 9 can be rotated in the opposite direction by pressing the reset button 25 to drive the lead screw 10 and the grating bracket 13 to reset to the initial position and prepare for the next measurement.

[0037] To sum up, the warpage measuring instrument drives the screw 10 through the motor 9 to drive the grating bracket 13 and the grating 14 to slide along the measuring slot 5, and combines the auxiliary positioning of the laser sensor and the laser sensor to achieve accurate scanning and measurement of the object to be measured placed in the measuring slot 5.

[0038] The above are only preferred embodiments of the present disclosure and are not intended to limit the patent scope of the present disclosure. Any equivalent structure or equivalent process transformation made using the contents of the present disclosure and the drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present disclosure.
