Abstract
Description
Technical Field
[0001] The utility model relates to the field of measuring instruments, in particular to a silk-screen hole-to-edge measuring instrument. Background Art
[0002] Conventional measurement of the distance from the screen printing hole to the glass edge uses a steel ruler or caliper. These two measurement methods have the following shortcomings:
[0003] 1) The steel ruler is simple to measure and easy to read, but the resolution is too low (resolution 0.5mm), and the positioning error is large (it cannot accurately locate the center of the silk screen hole), which easily leads to large errors when reading.
[0004] 2) Although the caliper has a high precision, it is also difficult to accurately locate the center of the silk screen hole and it is difficult to keep the measurement parallel to the glass surface. Therefore, the actual measurement error is large, and the vernier caliper is rarely used in actual applications.
[0005] Therefore, we propose a silk screen hole to edge measuring instrument to solve the above problems. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings and implementation examples.
[0019] Please refer to Figures 1 to 3 The instrument consists of three core components: an L-shaped base frame 1, a digital dial indicator 2, and a zeroing plate 3. The L-shaped base frame 1 serves as the supporting framework for the entire measuring instrument. Its inner side is securely connected to a connecting plate 4, forming a practical receiving slot 5 between the two. Mounting slots 6 are cleverly positioned within the L-shaped base frame 1 to facilitate the installation and securing of other components.
[0020] As a precision measuring tool, the digital micrometer 2 is securely mounted on the L-shaped base 1, its output terminal tightly connected to the movable base 7. The design of the movable base 7 allows for a flexible threaded connection to the L-shaped base 1 via screws 8. The ends of the screws 8 also form a rotational connection with the movable base 7, significantly enhancing the convenience and accuracy of measurement. The movable base 7 is equipped with not only a reference hole 9 but also a marking film 10 for precise alignment with the reference hole 11 on the zero calibration plate 3.
[0021] The bottom of the connecting plate 4 cleverly secures a lamp holder 12, while the top of the lamp holder 12 is embedded and secured with a plastic tube 13. The top of the plastic tube 13 is equipped with an LED lamp bead 14, providing the necessary illumination for the measurement process. Furthermore, the connecting plate 4 also features a light hole 15, which is aligned with the LED lamp bead 14, ensuring smooth light transmission.
[0022] To further enhance the stability and practicality of the measuring instrument, several support heads 16 are installed on the connecting plate 4 and the L-shaped base frame 1 opposite the receiving slot 5. These support heads 16 not only provide a stable support for the object to be measured, but also ensure the smooth progress of the measurement process.
[0023] In addition, the bottom of the movable base 7 is flush with the top inner wall of the L-shaped base 1, which makes the measurement more accurate and reliable. The detachable connection design between the digital dial indicator 2 and the L-shaped base 1 makes the entire measuring instrument more convenient to carry and maintain.
[0024] When using this measuring instrument for measurement, first check whether the measuring tools (i.e., digital dial indicator 2 and LED lamp 14) are functioning properly and whether the zero calibration plate 3 has any noticeable deformation. Then, perform the zero calibration operation. This involves pressing the power button on the LED lamp 14 and digital dial indicator 2. Place the zero calibration plate 3 into the receiving slot 5 with its edge against the inside of the L-shaped base 1. Adjust the movable seat 7 and rotating screw 8 to align the reference hole 11 on the marking film 10 with the reference hole 9. Finally, press the ZERO button on the digital dial indicator 2 to complete the zero calibration.
[0025] Now, it's time to begin the actual measurement. Place the glass to be measured into the holding tank 5, with its edge against the inside of the L-shaped base frame 1. Then, align the reference hole 11 on the marking film 10 with the reference hole 9. Now, read the value on the digital micrometer 2 to obtain the measurement result. It's worth noting that by using zero calibration plates 3 with different ranges, it's also possible to measure the distance from different silkscreen holes to the edge.
[0026] Furthermore, the measuring instrument utilizes a unique five-point support system. When measuring glass, the upper surface is supported by four points, and the lower surface is supported by one point (the support head 16 serves as the support point). This support system automatically locks the glass under its own weight, regardless of whether the glass surface is flat or curved, thus ensuring stable positioning and accurate measurement readings.
[0027] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
