Description

Technical Field

[0001] This invention relates to the field of tape-packaged product manufacturing technology, specifically to a warpage measurement instrument for tape-packaged products. Background Technology

[0002] Tape and reel packaging products are semi-transparent, elastic, and strong tape materials that can be wound onto reels for continuous feeding. They possess good flexibility and mechanical strength, providing protection and positioning for electrical components. Suitable for automated roll-to-roll processing in the electronics industry, they meet the requirements for moisture protection, anti-static properties, and high-efficiency production.

[0003] In the production of sheet / roll products, warpage detection is a critical quality control step. Typically, one sheet is sampled from each roll for inspection, although some customers require testing two sheets to ensure reliability. During inspection, three equidistant points are selected laterally on the product. Using an alignment platform, the product is suspended flat at the ends. The height difference between these points is measured, and the maximum value is taken as the warpage. The warpage is generally controlled within 6mm; defective products are rejected to prevent them from entering downstream electrical applications.

[0004] The existing testing fixture is composed of multiple stainless steel units, which is simple in structure. However, during measurement, it requires frequent manual movement of the scale to take readings point by point, which is cumbersome and inefficient. In addition, this fixture relies on visual observation, which is subject to significant differences in subjective judgment by personnel, easily leading to inconsistent measurement results and poor repeatability. Summary of the Invention

[0005] The purpose of this invention is to provide a warpage measurement instrument for roll-to-roll packaged products, in order to solve the problems of existing fixtures being made of stainless steel single-piece splicing, requiring manual movement of the scale to read the data point by point, which is cumbersome, relies on visual observation, has large subjective differences, poor repeatability, and low efficiency.

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Example 1 Tape-and-roll packaging products are semi-transparent, elastic, and strong strip materials that can be wound and fed into the machine. They are widely used in automated processing in the electronics industry and must meet requirements such as moisture resistance and anti-static properties. Warpage detection is a critical quality control step in production. Typically, 1 to 2 sheets are randomly sampled from each roll, with 3 points measured laterally. Warpage is generally controlled within 6mm. However, existing fixtures are made of assembled stainless steel units, requiring manual movement of the ruler to read the measurements point by point. This process is cumbersome and inefficient; furthermore, it relies on visual observation, which is subject to significant subjective variations and has poor measurement repeatability, making it difficult to meet high-precision quality control requirements.

[0023] To address the aforementioned issues, this embodiment provides a warpage measurement instrument for tape-packaged products, such as... Figure 1 As shown, it includes a support column 1, and a positioning mechanism 2 is provided on the upper side of the support column 1. In this embodiment, the positioning mechanism 2 includes a pressure block 201 placed on the top of the support column 1, which positions the root of the tape cutting piece.

[0024] A two-dimensional moving mechanism 9 is installed on the lower side of the support column 1. A laser displacement sensor 4 is mounted on the two-dimensional moving mechanism 9. The two-dimensional moving mechanism 9 can drive the laser displacement sensor 4 to move along the horizontal X and Y directions to detect the height of the corresponding position on the tape cutting sheet. A reference block 3 is installed on one side of the support column 1. The reference block 3 cooperates with the laser displacement sensor 4 to zero the laser displacement sensor 4. The laser displacement sensor 4 is electrically connected to a display panel 5, which is used to display the detection results of the laser displacement sensor 4.

[0025] In this embodiment, the tape cutting sheet is fixed to the top of the support column 1 by the pressure block 201. The operator adjusts the two-dimensional moving mechanism 9 to drive the laser displacement sensor 4 to move laterally. First, the laser displacement sensor 4 is calibrated using the reference block 3. Then, the laser displacement sensor 4 is adjusted to move laterally at the bottom of the tape cutting sheet, thereby collecting the height of three points at the bottom of the tape cutting sheet. The specific values ​​are displayed on the display panel 5. By measuring the height difference at each point, the maximum value is taken as the warpage. Under normal conditions, the warpage is typically controlled within 6mm; exceeding 10mm is considered abnormal. If the detection result is within 6mm to 10mm, multiple measurements of the tape cutting sheet are required for multiple tests to avoid errors. Defective products will be rejected to prevent them from flowing into downstream electrical applications.

[0026] After collecting a set of data, the laser displacement sensor 4 can be adjusted to move back and forth, thereby switching the detection point and selectively collecting 2 to 4 sets of detection results to improve the detection effect.

[0027] As an alternative, the two-dimensional adjustment mechanism includes two sets of linear motion modules arranged perpendicularly to each other, such as... Figure 1 As shown, the laser displacement sensor 4 is moved laterally and backward by two sets of threaded screws, thereby changing the detection point position, quickly achieving lateral positioning, and collecting data.

[0028] It should be emphasized that the core improvement of this embodiment lies in replacing the traditional manual reading method with a two-dimensional moving mechanism 9 driving the laser displacement sensor 4, thereby achieving faster and more accurate warpage detection. Two sets of mutually perpendicular linear moving modules drive the laser displacement sensor 4 to move precisely along the X and Y directions via threaded screws, automatically switching detection points without the need for manual handling of the ruler. The reference block 3 is used to zero the sensor, eliminating zero-point drift errors. During detection, the sensor horizontally collects the height of three points at the bottom of the cut piece, and the data is displayed in real time on the display panel 5. The maximum height difference is taken as the warpage. This solves the pain points of traditional fixtures, such as cumbersome operation, large visual errors, and poor repeatability.

[0029] Example 2 In Example 1, when the root of the tape cutter is fixed by the pressure block 201, it is difficult to determine whether the tape cutter is placed according to the standard or whether there is a deviation. Without a calibration or reference alignment structure, the tape cutter is easily misplaced, which makes the detection data too large or too small, affecting the subsequent judgment of the detection results.

[0030] To solve the above problems, such as Figures 2-4 As shown, the positioning mechanism 2 includes a positioning seat 202 rotatably mounted on the top of the support column 1. A movable pressure block 203 is rotatably mounted on one side of the positioning seat 202, forming an opening and closing clamping surface between the movable pressure block 203 and the positioning seat 202. The positioning seat 202 has a positioning groove 2023 for placing and limiting the position of the tape cutting sheet. The movable pressure block 203 has a positioning protrusion 2031 that cooperates with the positioning groove 2023. Figure 4 As shown, the surfaces of the positioning protrusion 2031 and the positioning groove 2023 are coated with an anti-slip coating. A rotating handle 207 is fixedly mounted on the rotation axis of one end of the positioning seat 202 for adjusting the forward or upward position of the clamping opening. A pull-out control assembly is provided on the positioning seat 202 for controlling the clamping state of the movable pressure block 203. A support boss 102 is provided on the upper side of the support column 1 for supporting the rear side of the positioning seat 202 when the clamping opening is facing upward, such as... Figure 4 As shown.

[0031] The positioning seat 202 has a guide hole 2021. The pull-out control component includes a push-pull rod 204 that slides inside the guide hole 2021. The movable pressure block 203 is made of magnetic metal, such as iron. Preferably, an iron fixing layer is fixedly installed on the inner side. A strong magnet 206 is fixedly installed at one end of the push-pull rod 204 near the movable pressure block 203. An elastic element 205 is provided between the push-pull rod 204 and the guide hole 2021. The elastic element 205 is used to elastically maintain the magnetic attraction state between the push-pull rod 204 and the movable pressure block 203.

[0032] An auxiliary plate 2022 is fixedly installed on the positioning seat 202. The auxiliary plate 2022 is located on one side of the guide hole 2021. The push-pull rod 204 can be pushed or pulled by the auxiliary plate 2022.

[0033] In this embodiment, after the test is completed, the auxiliary plate 2022 can be pulled with one finger to push the push-pull rod 204, which will cause the strong magnet 206 to squeeze the movable pressure block 203, thereby increasing the gap between the movable pressure block 203 and the positioning seat 202, making it easier to remove the tape cutting piece and avoiding wear of the clamping opening caused by direct dragging.

[0034] When it is necessary to load the wafer, the positioning seat 202 can be rotated 90° by rotating the handle 207, so that the bottom of the positioning seat 202 falls on the support boss 102 for stable support, with the clamping opening facing upward. Then, push the auxiliary plate 2022 with one finger, and use the force to pull the push-pull rod 204, which moves the strong magnet 206 away from the movable pressure block 203. The magnetic force released by the strong magnet 206 is not enough to support the gravity of the movable pressure block 203, thereby causing the movable pressure block 203 to separate from the positioning seat 202, exposing the positioning groove 2023.

[0035] Place the bottom of the tape cutter piece into the positioning groove 2023, as follows. Figure 5 As shown, ensure that the bottom of the tape cutting sheet is in parallel contact with the positioning groove 2023, and then push the movable pressure block 203. Due to the influence of the strong magnet 206, it will adhere to one side of the positioning seat 202, so that the positioning protrusion 2031 cooperates with the positioning groove 2023 to clamp the tape cutting sheet.

[0036] Then, by rotating the handle 207, the positioning seat 202 is rotated 90° in the opposite direction, so that the positioning seat 202 is reset, which facilitates subsequent testing operations.

[0037] It should be emphasized that the core improvement of this embodiment lies in replacing the simple clamping block 201 with a magnetic push-pull rod 204 assembly, enabling rapid loading and precise alignment of the cut pieces. When loading, rotating the handle 207 rotates the positioning seat 202 90° so that the clamping opening faces upwards. Pushing the auxiliary plate 2022 with one finger pulls the push-pull rod 204, causing the strong magnet 206 to move away from the movable clamping block 203, automatically separating it under gravity and exposing the positioning groove 2023 for placing the piece. After placement, the movable clamping block 203 automatically adheres due to magnetic attraction, and the positioning protrusion 2031 cooperates with the positioning groove 2023 to complete the limiting. When removing the piece, pulling the auxiliary plate 2022 with one finger causes the strong magnet 206 to squeeze the movable clamping block 203, increasing the gap for easier removal and preventing wear on the clamping opening. The positioning groove 2023 and the protrusion are coated with an anti-slip coating to ensure the cut pieces are placed parallel, eliminating data deviations caused by misalignment. The entire process can be completed with a single finger operation, improving loading efficiency and positioning accuracy.

[0038] Example 3 In the above embodiment, the tape cutting sheet is prone to elastic deformation due to inertia during the flipping process, resulting in up-and-down swaying and displacement of the tape cutting sheet within the positioning groove 2023. To improve efficiency, workers may also pinch the tape cutting sheet with their hands. However, during this pinching process, workers typically wear gloves for measurement, reducing their fingertip sensitivity. This can lead to the application of pushing force to overcome the swaying, causing the tape cutting sheet to move.

[0039] To address the aforementioned issues, buffer support brackets 7 are installed on both sides of the support column 1. Each buffer support bracket 7 includes counterweight arms 701 movably mounted on both sides of the support column 1. Support arms 702 are movably connected to the ends of the counterweight arms 701. A buffer pressure rod 704 is fixedly mounted on the front side of the support arm 702. The surface of the buffer pressure rod 704 is made of plastic foam to absorb the vibration of the tape cutting sheet. Adjustable arms 703 are movably connected to both sides of the support column 1, with the ends of the adjustable arms 703 movably connected to the ends of the support arms 702 near the counterweight arms 701. A one-way damper 8 is movably connected to the support column 1, enabling rapid stretching and slow compression. The output end of the one-way damper 8 is movably connected to the counterweight arms 701.

[0040] A linkage mechanism 6 is provided on one side of the support column 1 for adjusting the support angle of the counterweight arm 701. The linkage mechanism 6 includes a drive wheel 601 coaxially fixedly connected to the rotation axis of the positioning seat 202. A connecting shaft 604 is fixedly provided on one side of the support column 1, and a transmission wheel 602 is rotatably mounted at the end of the connecting shaft 604. The transmission wheel 602 and the drive wheel 601 are in a transmission engagement, for example... Figure 7 As shown, the transmission effect is achieved through the transmission belt 605. A rotating sleeve 603 is rotatably mounted on the connecting shaft 604, and the rotating sleeve 603 is fixedly connected to the counterweight arm 701. A driving block 6031 is eccentrically fixed inside the rotating sleeve 603, and a transmission block 6021 is eccentrically fixed inside the transmission wheel 602. The transmission block 6021 can drive the driving block 6031 to rotate synchronously in the forward direction. After the transmission block 6021 reverses and resets, the driving block 6031 also freely resets in the reverse direction. A storage groove 101 is provided on the front side of the support column 1 to store the buffer pressure rod 704.

[0041] In this embodiment, when the film needs to be loaded, rotating the handle 207 causes the positioning seat 202 to rotate 90°. At this time, the drive wheel 601 drives the transmission wheel 602 to rotate via the transmission belt 605. The transmission wheel 602 drives the drive block 6031 to perform circular motion via the transmission block 6021. Figure 8 As shown in (a), the drive block 6031 drives the rotating sleeve 603 to rotate, which in turn drives the counterweight arm 701 to perform circular motion. The counterweight arm 701 drives the support arm 702 to move, and the adjusting arm 703 rotates upward under the action of the support arm 702, while simultaneously applying a pushing force to the support arm 702. Figure 5 As shown, this allows the buffer lever 704 to be lifted.

[0042] After the tape cutting sheet is assembled, rotating the handle 207 causes the positioning seat 202 to rotate 90° in the opposite direction, resetting the positioning seat 202. This, in turn, causes the transmission block 6021 to reset via the drive wheel 601, transmission belt 605, and transmission wheel 602, thus removing the support from the drive block 6031. Figure 8As shown in (b), the counterweight arm 701 begins to move downwards under the action of gravity. The counterweight arm 701 drives the support arm 702 to move, and the adjusting arm 703 swings downwards under the action of the support arm 702, while applying a pulling force to the support arm 702, causing the adjusting arm 703 to retract and send the buffer rod 704 into the storage slot 101. The one-way damper 8 applies resistance to the counterweight arm 701, so that the step of storing the buffer rod 704 can be carried out slowly.

[0043] When the positioning seat 202 rotates 90° in the opposite direction, the tape cutting sheet will fall onto the buffer pressure bar 704. The buffer pressure bar 704 will absorb the inertia of the tape cutting sheet. At the same time, the buffer pressure bar 704 will slowly move away from the tape cutting sheet, so that the tape cutting sheet can slowly detach from the buffer pressure bar 704. After the tape cutting sheet loses its inertia, it will quickly settle down, which facilitates subsequent data acquisition.

[0044] It should be emphasized that the core improvement of this embodiment lies in the automatic elimination of inertia after the cut piece is flipped, achieved through the coordinated action of the buffer support 7 and the linkage mechanism 6, without the need for manual intervention affecting accuracy. When the rotating handle 207 drives the positioning seat 202 to rotate 90°, the linkage mechanism 6 synchronously drives the weight arm 701 to rise, and the foam buffer pressure rod 704 moves upward to receive the cut piece; after the positioning seat 202 resets, the transmission block 6021 loses support, and the weight arm 701 slowly moves downward under gravity with the help of the one-way damper 8, while the buffer pressure rod 704 simultaneously descends and is stored in the storage slot 101. At the moment of flipping, the cut piece falls onto the buffer pressure rod 704, the foam material absorbs the elastic vibration, and the buffer pressure rod 704 descends slowly to allow it to smoothly detach and quickly settle. No gloves are required to press throughout the process, avoiding the risk of displacement caused by fingertip force, ensuring the accuracy of subsequent laser data acquisition, and achieving automated connection from flipping to settling.

[0045] Working principle: The operator first rotates the positioning seat 202 90° by rotating the handle 207, so that the clamping opening faces upward, and the bottom of the positioning seat 202 is stably supported on the support boss 102. At this time, the drive wheel 601 drives the transmission wheel 602 to rotate through the transmission belt 605. The transmission wheel 602 drives the drive block 6031 to make a circular motion through the transmission block 6021. The rotating sleeve 603 rotates accordingly, the counterweight arm 701 makes a circular motion and drives the support arm 702 to move. The adjusting arm 703 rotates upward under the action of the support arm 702 and applies a pushing force. The buffer pressure rod 704 is then raised and placed in the receiving position.

[0046] Subsequently, the operator pushes the auxiliary plate 2022 with one finger, using the force to pull the push-pull rod 204. The strong magnet 206 moves away from the movable pressure block 203, and the magnetic force is insufficient to support the weight of the movable pressure block 203. The movable pressure block 203 separates from the positioning seat 202, exposing the positioning groove 2023. The bottom of the tape cutting sheet is then smoothly placed into the positioning groove 2023, ensuring parallel contact with the positioning groove 2023. After releasing the auxiliary plate 2022, the elastic element 205 maintains the magnetic attraction between the push-pull rod 204 and the movable pressure block 203. The strong magnet 206 attracts the movable pressure block 203 to adhere to one side of the positioning seat 202. The positioning protrusion 2031 cooperates with the positioning groove 2023 to achieve precise clamping and positioning of the tape cutting sheet.

[0047] The operator rotates the positioning seat 202 90° in the opposite direction by rotating the handle 207, resetting the positioning seat 202 so that the clamping opening faces forward. At this time, the linkage mechanism 6 operates in reverse. After the transmission block 6021 is reset, the drive block 6031 loses support, and the counterweight arm 701 begins to move downward under the action of gravity, driving the support arm 702 to move. The adjusting arm 703 swings downward and applies a pulling force, slowly sending the buffer pressure rod 704 into the storage slot 101. After the positioning seat 202 flips, the tape cutting sheet falls onto the buffer pressure rod 704. The plastic foam material on the surface of the buffer pressure rod 704 absorbs the elastic deformation and up-and-down swaying of the tape cutting sheet caused by inertia. The one-way damper 8 applies resistance to the counterweight arm 701, causing the buffer pressure rod 704 to slowly move away from the tape cutting sheet. The tape cutting sheet gradually loses support and quickly settles, preventing displacement in the positioning slot 2023.

[0048] The operator, wearing gloves, first moves the laser displacement sensor 4 to the reference block 3 for zeroing calibration. After calibration, the two-dimensional moving mechanism 9 is adjusted to move the laser displacement sensor 4 laterally along the horizontal X and Y directions at the bottom of the tape cutter sheet, sequentially collecting height data at three equidistant points. The specific values ​​are displayed in real time on the display panel 5. By calculating the height difference between each point and the reference surface, the maximum value is taken as the warpage of the tape cutter sheet. Under normal conditions, the warpage is typically controlled within 6mm to prevent it from affecting downstream electrical applications. If necessary, multiple measurements of the tape cutter sheet should be taken for repeated testing to avoid errors from a single measurement.

[0049] After all tests are completed, the operator pulls the auxiliary plate 2022 with one finger, using the force to push the push-pull rod 204. The strong magnet 206 squeezes the movable pressure block 203, making the gap between the movable pressure block 203 and the positioning seat 202 larger, so that the tape cutting piece can be taken out easily and the clamping mouth can be worn out due to direct dragging, thus completing the entire testing process.

Those skilled in the art should understand that this application is not limited to the above embodiments.
