Description

Technical Field

[0001] The utility model relates to the field of measuring jigs, in particular to a REEL measuring jig. Background Art

[0002] Chips are typically made from single-crystal silicon wafers. After dicing, the wafers are cut into multiple small crystals, or IC chips. These chips are typically spaced and fixed to a tape using a substrate. During the production process, the factory uses a recirculating REEL. After repeated use, the REEL's shape deteriorates beyond the specified specifications (deformation), potentially causing product defects during in-factory use. Factories regularly measure the REEL, typically using a vernier caliper. However, the softness of the REEL can lead to inaccurate readings during this process.

[0003] Inaccurate measurement will lead to misjudgment of the accuracy of REEL. In order to solve the above problems, we propose a REEL measurement fixture. Utility Model Content

[0004] The purpose of the utility model is to provide a REEL measuring jig, which has the advantage of being able to optimize the measuring technique and increase accuracy.

[0005] The above technical objectives of the present utility model are achieved through the following technical solutions: a REEL measuring jig, comprising a base plate, the top of the base plate is fixedly connected to a pillar, the interior of the pillar is rotatably connected to a rotating rod through a bearing, the surface of the rotating rod is fixedly sleeved with a clamping block 1, the surface of the rotating rod is also slidably connected to a clamping block 2, the surface of the rotating rod is sleeved with a fixed clamp, the internal thread of the fixed clamp is connected to an adjusting knob, one end of the adjusting knob is rotatably connected to the fixed clamp through a bearing, a movable platform is provided on the top of the base plate, the top of the movable platform is fixedly connected to a measuring plate, and two measuring slots are provided inside the measuring plate.

[0006] By adopting the above technical solution, the clamping and positioning of the REEL can be achieved by providing a support, a bearing, a rotating rod, a clamping block 1, a clamping block 2, a fixed clamp and an adjustment knob. By providing a measuring plate and opening a measuring slot inside the measuring plate, the REEL is driven to rotate inside the measuring slot by rotating the rotating rod. Whether the REEL is deformed can be measured by whether it can smoothly pass through the inside of the measuring slot. Compared with measuring the deformation of the REEL on both sides through a vernier caliper, the fixture is more accurate in measuring the deformation of the REEL and has higher measurement efficiency.

[0007] The present invention is further configured as follows: a receiving groove is provided on the top of the bottom plate, the movable platform is located inside the receiving groove, and the top of the movable platform and the top of the bottom plate are on the same horizontal line.

[0008] The above technical solution is adopted to store the mobile station through the provision of the storage slot.

[0009] The utility model is further configured as follows: both sides of the storage groove are connected with a slide groove, and the interior of the slide groove is slidably connected to a slider fixedly connected to the moving platform.

[0010] The above technical solution is adopted to guide the movement of the mobile platform forward and backward by setting the sliding groove and the slider, and can facilitate the position adjustment of the mobile platform by sliding inside the storage groove.

[0011] The utility model is further configured as follows: the internal thread of the movable platform is connected with a positioning knob, and the bottom end of the positioning knob is in contact with the bottom plate.

[0012] By adopting the above technical solution, the positioning knob is set and tightened so that its bottom end contacts the bottom plate. The friction between the bottom plate and the bottom end of the positioning knob is used to limit the movable platform and prevent the movable platform from sliding.

[0013] The utility model is further configured as follows: the surface of the rotating rod is used for sleeve-mounting the REEL, and the interior of the measuring groove is used for sliding contact with the REEL.

[0014] Using this technical solution, after the rotating rod and REEL are installed, the REEL is clamped and positioned by contacting one side of the REEL with clamping block one, contacting clamping block two with the other side of the REEL, and contacting the fixed clamp with clamping block two. By tightening the adjustment knob clockwise, clamping block two deforms, thereby clamping the surface of the rotating rod. If the REEL rotates through the measuring slot and detects no deformation, the measurement indicates that the REEL has deformed. If the REEL cannot pass through the measuring slot, the measurement result indicates that the REEL has deformed.

[0015] In summary, the present invention has the following beneficial effects:

[0016] The utility model can achieve the clamping and positioning of the REEL by providing a support, a bearing, a rotating rod, a clamping block 1, a clamping block 2, a fixed clamp and an adjusting knob. By providing a measuring plate and opening a measuring slot inside the measuring plate, the REEL is driven to rotate inside the measuring slot by rotating the rotating rod. Whether the REEL is deformed can be measured by whether the REEL can smoothly pass through the inside of the measuring slot. Compared with measuring the data of whether the REEL is deformed by the fixture through the two sides of the vernier caliper, the measurement data of whether the REEL is deformed is more accurate and the measurement efficiency is higher.

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] Example 1:

[0024] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A REEL measuring fixture includes a base plate 1, a support 2 is fixedly connected to the top of the base plate 1, a rotating rod 3 is rotatably connected to the interior of the support 2 through a bearing, a clamping block 4 is fixedly sleeved on the surface of the rotating rod 3, and a clamping block 2 5 is slidably connected to the surface of the rotating rod 3, a fixed clamping hoop 6 is sleeved on the surface of the fixed clamping hoop 6, an adjusting knob 7 is connected to the internal thread of the fixed clamping hoop 6, and one end of the adjusting knob 7 is rotatably connected to the fixed clamping hoop 6 through a bearing, a moving platform 8 is provided on the top of the base plate 1, and a measuring plate 9 is fixedly connected to the top of the moving platform 8, and two measuring plates are provided inside the measuring plate 9. The REEL is clamped and positioned by providing a support 2, a bearing, a rotating rod 3, a clamping block 1 4, a clamping block 2 5, a fixed clamp 6 and an adjusting knob 7. A measuring plate 9 is provided and a measuring slot 10 is opened inside the measuring plate 9. The REEL is driven to rotate inside the measuring slot 10 by rotating the rotating rod 3. Whether the REEL can smoothly pass through the inside of the measuring slot 10 can be measured to determine whether the REEL is deformed. Compared with measuring the REEL on both sides using a vernier caliper, the fixture is more accurate in measuring the deformation of the REEL and has higher measurement efficiency.

[0025] Furthermore, a storage groove 11 is provided on the top of the base plate 1, and the movable platform 8 is located inside the storage groove 11. The top of the movable platform 8 and the top of the base plate 1 are on the same horizontal line. The storage groove 11 is provided to store the movable platform 8.

[0026] Furthermore, both sides of the storage groove 11 are connected with a slide groove 12, and the inside of the slide groove 12 is slidably connected to a slider 13 fixedly connected to the movable platform 8. Through the setting of the slide groove 12 and the slider 13, the movement of the movable platform 8 is guided forward and backward, and the position of the movable platform 8 can be adjusted by sliding inside the storage groove 11.

[0027] Furthermore, the internal thread of the movable platform 8 is connected with a positioning knob 14, and the bottom end of the positioning knob 14 contacts the base plate 1. By setting the positioning knob 14, the positioning knob 14 is tightened so that its bottom end contacts the base plate 1. The friction force between the base plate 1 and the bottom end of the positioning knob 14 can be used to limit the movable platform 8 to prevent the movable platform 8 from sliding.

[0028] Furthermore, the surface of rotating rod 3 is used to fit the REEL, and the interior of measuring slot 10 is designed to slide in contact with the REEL. After rotating rod 3 and REEL are fitted, the REEL is positioned by contacting one side of the REEL with clamping block 1 4, contacting clamping block 2 5 with the other side of the REEL, and fixing clamp 6 with clamping block 2 5. By tightening adjustment knob 7 clockwise, clamping block 2 5 deforms, thereby clamping the surface of rotating rod 3. By rotating the REEL through measuring slot 10, it can be measured that the REEL has not deformed. If the REEL cannot pass through measuring slot 10, the measurement result indicates that the REEL has deformed.

[0029] Brief description of the usage process:

[0030] During the test, first rotate the adjusting knob 7 counterclockwise to push one side of the fixing hoop 6 away from the other side of the fixing hoop 6 through the reverse thread of the adjusting knob 7, thereby expanding the internal space of the fixing hoop 6 and making it unable to clamp the rotating rod 3;

[0031] Then remove the fixed clamp 6, then remove the clamping block 2 5, and fit the REEL onto the surface of the rotating rod 3, pushing one side of the REEL into contact with the clamping block 1 4. After fitting the clamping block 2 5 onto the surface of the rotating rod 3 and pushing it into contact with the REEL, fit the fixed clamp 6 onto the rotating rod 3, pushing one side of the fixed clamp 6 into contact with the clamping block 2 5. By rotating the adjustment knob 7 clockwise, the threads of the adjustment knob 7 pull the two sides of the fixed clamp 6 together. At this time, the internal space of the fixed clamp 6 shrinks, clamping it to the surface of the rotating rod 3. At this time, the REEL cannot rotate on the surface of the rotating rod 3 due to the friction between the clamping blocks 1 4 and the clamping block 2 5 on both sides. Only when the rotating rod 3 rotates, which drives the clamping block 1 4 to rotate, and the clamping block 1 4 drives the REEL to rotate, can the REEL rotate.

[0032] Then push the moving platform 8 to move inside the receiving groove 11 until the inside of the measuring groove 10 is set to the REEL. Figure 3After the position of the moving platform 8 is determined, the positioning knob 14 is tightened so that the threaded end of the positioning knob 14 contacts the top of the bottom plate 1, and the position of the moving platform 8 is limited by friction.

[0033] By rotating the fixed clamp 6, it drives the rotating rod 3 inside it to rotate, and the rotation of the rotating rod 3 drives the clamping block 1 4 to rotate. The friction between the clamping block 1 4 and the clamping block 2 5 limits the position of the REEL. When the clamping block 1 4 rotates, the REEL also rotates. By the REEL rotating inside the measuring slot 10 and the REEL passing through the measuring slot 10 normally, the REEL measurement result is judged as no deformation or deformation.

[0034] The REEL cannot pass through the measuring groove 10 . During the rotation process, the applied force increases. Furthermore, by observing that the REEL has obvious deviation inside the measuring groove 10 , it is determined that the REEL measurement result is deformed.

[0035] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
