Description

Technical Field

[0001] This utility model relates to the field of flat panel product screen measurement technology, and in particular to a measuring fixture. Background Technology

[0002] During the design and prototyping of tablet products, various parameters need to be tested to verify and optimize the product design. Among these tests, screen gap and breakage measurement are crucial quality control steps in the prototyping and design phases, serving as important tools for evaluating product tolerances, IP ratings, and structural strength. Due to the small number of products produced during the design and prototyping stages, the industry primarily uses manual measurement methods for screen gaps and breakages, employing appropriate rulers. However, limitations in operator skill levels make it difficult to ensure consistency in measurement points when measuring multiple tablet samples. This results in measurements being taken at different points, leading to erroneous results and misleading design optimization. Furthermore, measuring screen gaps and breakages requires multiple adjustments to the product position and separate measurements, making the process cumbersome and inefficient. Utility Model Content

Each floating calibrator is provided with an indicator portion corresponding to the scale line on the scale marker, and at least one of the floating calibrators is provided on the base in the area corresponding to each scale marker.

[0005] In one embodiment, the base has a rectangular plate structure. The four side walls of the base include two first side surfaces that are opposite to each other and extend along the length of the base, and two second side surfaces that are opposite to each other and extend along the width of the base.

Detailed Implementation

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Please see Figure 1This utility model discloses a measuring fixture that can reduce measurement errors and improve measurement efficiency. The measuring fixture includes a base 100 and a calibration component. The base 100 is used to support the product (flat product) to be measured and provides a space for product measurement operations. The calibration component provides movable indicators during product measurement to accurately indicate the corresponding dimensional parameters of the product. Specifically, the upper surface of the base 100 has a rectangular placement slot 110 for accommodating the product. The inner contour shape of the rectangular placement slot 110 is adapted to the outer contour shape of the product; that is, the flat product itself is a rectangular plate structure. When the flat product is placed in the rectangular placement slot 110, the circumferential side of the flat product abuts against the inner circumferential side of the rectangular placement slot 110. Scale markings 120 are provided on the four sides of the opening of the rectangular placement slot 110 on the upper surface of the base 100. Each scale marking 120 includes several scale lines arranged sequentially and evenly along the length or width direction of the rectangular placement slot 110, facilitating accurate positioning when the floating calibrator moves. The scale lines at the end of the scale marker 120 are aligned with the corner of the rectangular placement slot 110, ensuring that the edges of the products are aligned with the initial scale lines of the scale marker 120 after the products are placed into the rectangular placement slot 110, thus guaranteeing measurement accuracy. In this embodiment, four scale markers 120 arranged in a circular path are provided on the edge of the slot opening of the rectangular placement slot 110. Two opposing scale markers 120 are arranged along the length of the rectangular placement slot 110, and the other two opposing scale markers 120 are arranged along the width of the rectangular placement slot 110. In addition, one end of the scale line of the scale marker 120 adjacent to the rectangular placement slot 110 extends to the opening of the rectangular placement slot 110. In this way, when the product is placed into the rectangular placement slot 110, the distance between the scale line and the edge of the product can be reduced, avoiding large reading errors caused by parallax due to the scale line being far from the product edge, thereby improving the accuracy of the measurement results. The calibration assembly includes multiple floating calibrators 200 mounted on the side of the base 100 and whose positions are adjustable along the length or width of the base 100. That is, the floating calibrators 200 can move along the length or width of the base 100 to adjust their calibrated positions. Each floating calibrator 200 has an indicator portion corresponding to a scale line on the scale marker 120. In this embodiment, the size of the indicator portion on the floating calibrator 200 needs to meet the following requirement: when the indicator portion corresponds to the corresponding scale line, the indicator portion contacts the end of the scale line away from the rectangular placement groove 110, or the indicator portion partially overlaps the end of the scale line away from the rectangular placement groove 110, to reduce the distance between the indicator portion and the scale line, thereby further reducing reading errors. The upper surface of the base 100 is provided with several grooves spaced apart to form scale lines, thus preventing the scale lines from interfering with the movement of the indicator portion of the floating calibrator.In this embodiment, at least one floating calibrator 200 is provided on the base 100 corresponding to the area of ​​each scale marker 120, so that the operator can measure the relevant parameters of the product from multiple directions. In actual measurement, multiple floating calibrators 200 can be set at intervals in the area where each scale marker 120 is located, according to specific measurement needs. That is, the number of floating calibrators 200 in each direction can be increased or decreased as needed. For example, the corresponding floating calibrators 200 can be fixed at multiple preset points on the scale marker 120. When measuring the product, it is only necessary to determine whether the corresponding part of the product corresponds to the corresponding floating calibrator 200 to determine whether the size of the product is qualified.

[0018] Please combine Figure 1-3The base 100 has a rectangular plate-like structure. The four side walls of the base 100 include two first side surfaces 101 that are opposite each other and extend along the length of the base 100, and two second side surfaces 102 that are opposite each other and extend along the width of the base 100. The first side surfaces 101 are perpendicular to the second side surfaces 102. A first I-shaped groove 103 is formed on the first side surface 101, extending along the length of the base 100 and penetrating through the two second side surfaces 102. A second I-shaped groove 104 is formed on the second side surface 102, extending along the width of the base 100 and penetrating through the two first side surfaces 101. A floating calibrator 200 is installed at both the first I-shaped groove 103 and the second I-shaped groove 104. The first I-shaped groove 103 and the second I-shaped groove 104 are used to limit the sliding path of the floating calibrator 200 along the length or width of the base 100, so as to avoid frequent changes in the position of the floating calibrator 200 along the thickness direction of the base 100 during position adjustment, and to reduce the difficulty of position adjustment of the floating calibrator 200. Furthermore, the first I-beam groove 103 includes a first limiting area 1031 and a first notch 1032 that communicates with the first limiting area 1031 and penetrates the first side surface 101. The dimension of the first notch 1032 along the thickness direction of the base 100 is smaller than the dimension of the first limiting area 1031 along the thickness direction of the base 100. The second I-beam groove 104 includes a second limiting area 1041 and a second notch 1042 that communicates with the second limiting area 1041 and penetrates the second side surface 102. The dimension of the second notch 1042 along the thickness direction of the base 100 is smaller than the dimension of the second limiting area 1041 along the thickness direction of the base 100. In other words, the inner side of the first I-beam groove 103 (the side of the first I-beam groove 103 adjacent to the rectangular placement groove 110) along the thickness direction of the base 100 is larger than the outer side of the first I-beam groove 103 (the side of the first I-beam groove 103 away from the rectangular placement groove 110) along the thickness direction of the base 100; the inner side of the second I-beam groove 104 (the side of the second I-beam groove 104 adjacent to the rectangular placement groove 110) along the thickness direction of the base 100 is larger than the outer side of the second I-beam groove 104 (the side of the second I-beam groove 104 away from the rectangular placement groove 110) along the thickness direction of the base 100, so as to cooperate with the corresponding part on the floating calibrator 200 to limit the floating calibrator 200 along the width direction of the first I-beam groove 103 or the width direction of the second I-beam groove 104, and prevent the floating calibrator 200 from falling off the base 100.

[0019] The floating calibrator 200 includes an L-shaped pointer 210, a nut 220, and a screw 230. The L-shaped pointer 210 includes a horizontal portion 211 located above the base 100 and near the edge of the upper surface of the base 100, and a vertical portion 212 fixedly connected to one end of the horizontal portion 211 facing away from the rectangular placement groove 110 and abutting against the first side 101 or the second side 102. One end of the horizontal portion 211 near the rectangular placement groove 110 forms an indicator portion. The nut 220 is slidably installed in the first limiting area 1031 or the second limiting area 1041. The screw 230 passes through the vertical portion 212 and the first notch 1032 of the L-shaped pointer 210 and is threadedly connected to the nut 220, or the screw 230 passes through the vertical portion 212 and the second notch 1042 of the L-shaped pointer 210 and is threadedly connected to the nut 220. That is, the vertical portion 212 of the L-shaped pointer 210 has a through hole for the screw 230 to pass through. In this embodiment, the distance between the lower surface of the horizontal portion 211 of the L-shaped pointer 210 and the upper surface of the base 100 is greater than 0. That is, the horizontal portion 211 of the L-shaped pointer 210 is suspended above the base 100, or the horizontal portion 211 of the L-shaped pointer 210 forms a cantilever above the base 100. This avoids the problem of the horizontal portion 211 of the L-shaped pointer 210 being scratched when it moves along the length or width direction of the base 100 under the drive of the screw 230, due to contact between the horizontal portion 211 of the L-shaped pointer 210 and the upper surface of the base 100, thus extending the service life of the L-shaped pointer 210. Furthermore, the outer contour shape of the nut 220 is adapted to the inner contour shape of the first limiting area 1031 or the inner contour shape of the second limiting area 1041. In particular, in this embodiment, the nut 220 has a rectangular block structure, and a threaded hole is provided on one side of the nut 220 for the screw 230 to be inserted. By adapting the outer contour shape of the nut 220 to the inner contour shape of the first limiting area 1031 or the second limiting area 1041, the nut 220 can be limited, allowing it to slide only along the length direction of the first I-beam groove 103 or the second I-beam groove 104. This prevents the nut 220 from rotating synchronously with the screw 230, ensuring the reliability of the screw 230 locking the L-shaped pointer 210. Thus, when measuring the product, simply loosen the screw 230, moving it away from the product. This reduces the pressure of the screw head on the vertical part 212 of the L-shaped pointer 210, releasing the constraint of the screw head and the side of the base 100 on the L-shaped pointer 210. This unlocks the floating calibrator 200, allowing the screw head to be pulled along the length or width direction of the base 100, causing the screw head to move synchronously with the nut 220 and the L-shaped pointer 210, thereby adjusting the position of the floating calibrator 200.Once the floating calibrator 200 has moved to the preset position, simply rotate the screw 230 in the opposite direction so that the screw head of the screw 230 presses against the vertical part 212 of the L-shaped pointer 210, thereby positioning the L-shaped pointer 210 and fixing the floating calibrator 200 on the base 100. This locks the floating calibrator 200 to prevent measurement errors caused by the movement of the floating calibrator 200 during the measurement process.

[0020] In one embodiment, the horizontal portion 211 of the L-shaped pointer 210 has a triangular plate-like structure, and one end of the horizontal portion 211 adjacent to the rectangular placement slot 110 has a tapered structure to form an indicating portion. That is, the width of the horizontal portion 211 of the L-shaped pointer 210 gradually decreases along the direction close to the rectangular placement slot 110. Preferably, the horizontal portion 211 of the L-shaped pointer 210 has an acute-angled isosceles triangle structure. In addition, in this embodiment, a handle 240 is fixed to one end of the screw 230 facing away from the nut 220. The handle 240 constitutes the screw head of the screw 230 and is used to provide an operating part when rotating the screw 230. Preferably, the handle 240 is provided with anti-slip texture to increase the friction coefficient of the handle 240 surface and prevent slippage when rotating the handle 240, thereby reducing the difficulty of locking and unlocking the floating calibrator 200.

[0021] It should be noted that in this embodiment, an L-shaped notch 105 is provided at each of the four corners of the base 100, and the L-shaped notch 105 communicates with the first I-beam groove 103 and the second I-beam groove 104. That is, a total of four L-shaped notches 105 are provided at the four corners of the base 100. The L-shaped notches 105 separate the adjacent first I-beam groove 103 and second I-beam groove 104. In this way, when assembling and disassembling the floating calibrator 200, multiple floating calibrators 200 on the four sides of the base 100 can be assembled and disassembled at the same time, without having to assemble and disassemble the floating calibrators 200 on each side one by one in sequence. This avoids interference when assembling and disassembling the floating calibrators 200 on adjacent sides, thereby improving the efficiency of assembling and disassembling the floating calibrator 200 on the base 100.

[0022] Please see Figure 4In one embodiment, the bottom surface of the rectangular placement slot 110 is provided with a foot pad clearance slot or foot pad clearance hole 130 corresponding to the product foot pad. That is, the corresponding slot or hole in the rectangular placement slot 110 for accommodating the product foot pad can either penetrate through the lower surface of the base 100 or be provided on the bottom surface of the rectangular placement slot 110 without penetrating the lower surface of the base 100. By providing a foot pad clearance slot or foot pad clearance hole 130 on the bottom surface of the rectangular placement slot 110, the measurement error caused by the soft foot pad at the bottom of the product can be avoided. The inner wall surface of the rectangular placement slot 110 is provided with a button clearance slot 140 corresponding to the product button and penetrating through the upper surface of the base 100. The button clearance slot 140 is used for both clearance of the product power switch button and restriction of the product positioning orientation, thereby preventing mistaken insertion of the product into the rectangular placement slot 110.

[0023] The measuring fixture of this invention features scale markers 120 around the base 100, with at least one adjustable floating calibrator 200 at each scale marker 120. The pointing position of the floating calibrator 200 can be adjusted as needed. When manually measuring screen gaps and the discontinuity between the screen and the casing, the product in the rectangular placement slot 110 is pushed to one corner of the slot, ensuring contact between the product and at least two adjacent inner walls of the slot. By fixing the corresponding floating calibrators 200, the measurement points for each sample are identical, reducing or even eliminating measurement errors and preventing erroneous measurement results from misleading design optimization. Simultaneously, when the product is positioned, adjusting the position of the corresponding floating calibrators 200 allows for the measurement of screen gaps and discontinuities, effectively improving measurement efficiency and facilitating efficient and accurate data acquisition, providing timely and accurate data support for design optimization.

[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0025] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
