Description

Technical Field

[0001] This utility model relates to the field of dicing blade thickness measurement technology, specifically an improved dicing blade thickness measurement device. Background Technology

[0002] A dicing blade is a precision cutting tool used in semiconductor chip manufacturing and back-end packaging processes. It functions like an extremely precise "diamond cleaver" to separate individual chips on a wafer. After the dicing blade is pressed and shaped, its dimensions need to be further inspected, including thickness. Therefore, a thickness measuring device is required to measure the thickness of the dicing blade to ensure that its thickness meets the process design standards.

[0003] An investigation revealed that a Chinese utility model patent discloses a dicing blade thickness measuring device (publication number: CN222993636U), comprising a base plate, a vertical plate on one side of the base plate, a horizontal plate at the top of the vertical plate, side plates on both sides of the vertical plate, an opening in the horizontal plate, a slide rail between the side plates, a mounting plate on the slide rail, a mounting seat on the mounting plate, a baffle on the mounting seat, a display mounting bracket at the top of the vertical plate, a display inside the display mounting bracket, and an alarm light at the top of the display mounting bracket.

[0004] Although the aforementioned patent, compared with existing technologies, uses a baffle to measure the thickness of the dicing blade, which is simple, quick, and efficient, eliminating the need for constant micrometer adjustments, it still has some shortcomings in practical use. The aforementioned patent and common measuring devices on the market typically require manual adjustment of a precision jack each time to determine whether the value meets the standard. However, in industry, only the standard needs to be met. The frequent reading and judgment process not only increases the workload of operators but may also lead to defective products flowing into the next process due to human error in reading or judgment.

[0005] Therefore, this utility model provides an improved device for measuring the thickness of a dicing blade to solve the above problems. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This invention, through the configuration of a precision micrometer, an alarm light, a first power supply connection, and a placement block, allows for precise measurement of the dicing blade's thickness after the precision micrometer is adjusted to the predetermined thickness and the blade is placed on the placement block. If the blade can be placed, the precision micrometer receives information and triggers the alarm light via the first power supply connection. If the blade cannot be placed, the circuit is open, and the light will not illuminate. This design not only reduces the workload of operators but also allows for quick judgment of whether the dicing blade's thickness meets the standard through intuitive light signals, effectively reducing measurement deviations caused by human error and improving the reliability of measurement results.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides an improved device for measuring the thickness of a dicing blade, such as... Figure 1-4 As shown, the thickness measuring device includes a base plate 1, a precision micrometer 2 fixedly connected to the base plate 1, an alarm light 3 installed on the base plate 1, a first power supply wire 4 connected to the power supply inside the precision micrometer 2, the end of the first power supply wire 4 away from the precision micrometer 2 being connected to the internal power supply of the alarm light 3, a battery 5 fixedly connected to the outer wall of the base plate 1, a second power supply wire 6 connected to the power supply inside the battery 5, the end of the second power supply wire 6 away from the battery 5 being connected to the internal power supply of the alarm light 3, a placement block 7 fixedly connected to the base plate 1, and the anvil below the precision micrometer 2 located inside the placement block 7 and parallel to the placement surface of the placement block 7.

[0026] Specifically, when it is necessary to measure the thickness of the dicing blade, first adjust the predetermined thickness of the precision micrometer 2, and use the gap between the anvil below it and the placement surface of the placement block 7 to form a suitable gap for inserting the dicing blade. Then, place the dicing blade stably on the placement surface of the placement block 7 and push it towards the anvil of the precision micrometer 2. If the dicing blade can be smoothly pushed into the anvil, the anvil part of the precision micrometer 2 will transmit the information to the alarm light 3 through the first power connection 4. At this time, the alarm light 3 will light up, indicating that the thickness of the dicing blade meets the design standard preset by the process.

[0027] If the dicing blade cannot be smoothly pushed into the anvil direction, it indicates that its thickness exceeds the preset process standard. At this time, the anvil part of the precision micrometer 2 will not trigger the alarm signal transmission, and the alarm light 3 will remain off. The battery 5 provides stable power support to the entire alarm system through the second power supply connection 6, ensuring the continuity and reliability of power supply during the measurement process. The placement surface of the placement block 7 is precision machined to ensure that the parallelism error between it and the anvil is controlled within 0.001mm, effectively avoiding measurement deviation caused by the tilt of the placement surface. In actual operation, the operator only needs to complete the adjustment, placement and pushing actions in sequence according to the above steps, and can intuitively judge whether the thickness of the dicing blade is qualified by the on / off state of the alarm light 3. The entire measurement process does not require complicated reading calculations, nor does it require frequent calibration of the parameters of the precision micrometer 2, which greatly reduces the dependence on the professional skills of the operator. This intuitive judgment method not only simplifies the operation process, but also significantly improves the measurement efficiency and reduces the misjudgment of unqualified products caused by human reading errors or operational mistakes.

[0028] The placement block 7 is provided with a cleaning edge 8, and the cleaning surface of the cleaning edge 8 is tapered.

[0029] The outer wall of the cleaning edge 8 is fixedly connected to a connecting rod 9, which is slidably connected to the base plate 1.

[0030] A spring 10 is fixedly connected to the outer wall of the cleaning edge 8 on the outer ring of the connecting rod 9. The end of the spring 10 away from the cleaning edge 8 is fixedly connected to the base plate 1.

[0031] A connecting plate 11 is fixedly connected to the end of the connecting rod 9 away from the cleaning shovel edge 8, and a squeezing cam 12 is rotatably connected to the base plate 1.

[0032] The extrusion cam 12 contacts the connecting plate 11, and the base plate 1 is equipped with a motor 13 for driving the extrusion cam 12 to rotate.

[0033] Specifically, when it is necessary to clean the impurities on the placement surface of the placement block 7 to ensure the accuracy of subsequent measurements, the operator first starts the motor 13. The motor 13 drives the extrusion cam 12 to rotate. During the rotation, the extrusion cam 12 periodically extrudes the connecting plate 11, forcing the connecting plate 11 to drive the connecting rod 9 to slide closer to the placement block 7. At this time, the spring 10 is stretched and stores elastic potential energy. As the connecting rod 9 moves, the cleaning shovel 8 at its front end also moves. Since the cleaning surface of the cleaning shovel 8 is conical, when it contacts the placement surface of the placement block 7, the conical cleaning surface can quickly insert into the gap between the impurities and the placement surface, removing the impurities. The impurities are scooped up and pushed away from the placement surface. When the cam of the squeezing cam 12 rotates to another position, the squeezing force of the squeezing cam 12 on the connecting plate 11 disappears, and the stretched spring 10 releases its elastic potential energy. Through the connecting rod 9, it drives the cleaning shovel edge 8 to move in the opposite direction, so that it returns to its initial position, waiting for the next squeezing cam 12 to squeeze the connecting plate 11 again for cleaning. This automatic cleaning structure does not require the operator to manually wipe the placement surface, avoiding scratches or secondary pollution that may be caused to the placement surface during manual cleaning. At the same time, the cleaning action is continuous and efficient, and the impurity cleaning work can be completed in a short time, further ensuring the continuity and accuracy of the dicing blade thickness measurement.

[0034] A drop hole 14 is provided on the base plate 1, and a collection box 15 is slidably connected inside the base plate 1.

[0035] Specifically, after the cleaning shovel 8 scoops up and pushes away the impurities from the placement surface of the placement block 7, the impurities will fall into the collection box 15 through the drop hole 14 under the action of gravity. The sliding connection design between the collection box 15 and the bottom plate 1 allows the operator to directly pull the collection box 15 out of the bottom plate 1 when the impurities accumulate to a certain extent, and centrally process the collected impurities. After processing, the collection box 15 can be pushed back to its original position. This structural design realizes the automated collection of impurities, avoids impurities scattering on the placement block 7 or the bottom plate 1, reduces the workload of subsequent manual cleaning of impurities, and maintains the overall cleanliness of the device, further improving the convenience and hygiene of the device during use.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
