Description

Technical Field

[0001] This utility model relates to the field of carrier tape detection technology, specifically a carrier tape forming surface protrusion detection mechanism. Background Technology

[0002] In the field of electronic component manufacturing and packaging, carrier tape, as a key packaging material used to carry and transport electronic components, directly affects the subsequent assembly accuracy and reliability of electronic components. During the carrier tape forming process, defects such as bumps may appear on its surface due to various factors such as raw material quality, production equipment precision, and process parameter control. If these bumps are not detected and removed in time, they may cause damage to components, poor contact, or even affect the performance of the entire electronic device during subsequent packaging, transportation, and assembly, resulting in huge economic losses.

[0003] Therefore, efficient and accurate detection of bumps on the carrier tape forming surface is crucial. Currently, various bump detection mechanisms for carrier tape forming surfaces exist on the market, but these mechanisms still have many shortcomings in practical applications. Some testing organizations use fixed testing heads to inspect the surface of carrier tapes. However, due to the differences in specifications among different carrier tape models, it is difficult to quickly and accurately adapt the position of the testing head to carrier tapes of different widths and thicknesses, resulting in a limited testing range and poor versatility. Moreover, during the testing process, the transmission of the carrier tape may deviate due to the lack of effective limiting, making the relative position between the testing head and the carrier tape surface unstable, affecting the testing accuracy, and easily leading to missed or false detections. Meanwhile, the installation and replacement process of existing testing components is cumbersome. When a testing component malfunctions or requires replacement with different types of testing heads according to testing needs, the operation is complex and time-consuming, affecting testing efficiency. Therefore, those skilled in the art have provided a carrier tape forming surface bump testing mechanism to solve the problems mentioned in the background art. Utility Model Content

[0017] Please see Figures 1-5 This utility model provides a technical solution: A carrier tape forming surface bump detection mechanism, comprising: Inspection table 1 is equipped with a winding mechanism for winding carrier tape. The winding mechanism includes two support plates 10, side plates 34, a drive motor 11, two pulleys 12, a transmission belt 13, and two winding rollers 14. The two support plates 10 are fixedly connected to both sides of the inspection table 1, and the two winding rollers 14 are rotatably connected to the support plates 10. The two pulleys 12 are connected to the winding rollers 14 through rotating rods 15, and the two pulleys 12 are connected through the transmission belt 13. 11 is installed on the testing table 1, and the output end of the drive motor 11 is connected to one of the pulleys 12. The side plate 34 is installed on the testing table 1 by bolts, and the side plate 34 is connected to the take-up roller 14 by bearing 35. The take-up roller 14 is connected to the take-up reel 16. Both the take-up reel 16 and the bearing 35 are provided with limit blocks 17. The take-up roller 14 is provided with a limit groove 18. The limit block 17 is slidably connected in the limit groove 18, and the take-up reel 16 is connected to the take-up roller 14 by bolts. When installing the take-up reel 16, the side plate is removed and the take-up reel 16 is fitted onto the take-up roller 14. At this time, the limiting block 17 on the take-up reel 16 will slide in the limiting groove 18 of the take-up roller 14. After sliding to the appropriate position, the bolts are tightened to fix it, thus completing the positioning of the take-up reel 16. Then, the limiting block 17 on the bearing 35 is engaged in the limiting groove 18. Finally, the side plate 34 is fixed to the inspection table 1 with bolts to complete the support of the take-up roller 14.

[0018] A support frame 2 is installed on the testing table 1, an electric push rod 3 is installed on the support frame 2, a movable frame 4 is connected to the output end of the electric push rod 3, several testing components are connected to the movable frame 4, and a limit mechanism is installed on the testing table 1 through a bidirectional electric slide rail 5. Several detection components include a connector 6, a telescopic assembly, a pressure sensor 7, a connecting plate 8, and a detection head 9. The connector 6 is connected to the moving frame 4 via a snap-fit ​​assembly, and the connector 6 is connected to the connecting plate 8 via the telescopic assembly. The pressure sensor 7 is installed between the detection head 9 and the connecting plate 8. The telescopic assembly includes a first return spring 19, a fixing rod 20, and an adjusting rod 21. The fixing rod 20 is fixedly connected to the connector 6, and a first mounting groove 22 is provided on the fixing rod 20. One end of the first return spring 19 is installed in the first mounting groove 22, and the other end of the first return spring 19 is connected to the adjusting rod 21. The other end of the adjusting rod 21 is connected to the connecting plate 8.

[0019] During carrier tape production, the bumps on the carrier tape surface can significantly impact downstream customers' tape packaging and sealing processes. Bumps can lead to poor sealing, affecting the product's airtightness and integrity, and can also cause tape jamming, reducing production efficiency. Therefore, accurate detection of bumps on the carrier tape surface is crucial.

[0020] During testing, one end of the carrier tape is fixed to the take-up reel 16. The controller 32 starts the drive motor 11, and the output of the drive motor 11 drives one of the pulleys 12 to rotate. Through the transmission belt 13, the other pulley 12 also rotates, thereby driving the two take-up rollers 14 to rotate synchronously. The take-up reel 16 rotates together with the take-up rollers 14 to realize the winding and transmission of the carrier tape. The support plate 10 provides single-sided support for the take-up rollers 14, ensuring the stable rotation of the take-up rollers 14 while facilitating the loading and unloading of the carrier tape. This testing mechanism has an online testing function, which can perform testing in real time during the carrier tape production process. During the testing process, a photoelectric sensor 33 is installed on the support frame 2. When the carrier tape moves to the testing position, a pause signal is triggered. After receiving the photoelectric signal, the controller 32 pauses the drive motor and starts the electric push rod 3 to press down for testing. The testing head 9 contacts the surface of the carrier tape, and the carrier tape stops transporting and winding. The pressure sensor 7 monitors the contact pressure between the two in real time and feeds the pressure signal back to the controller 32. If the pressure is abnormal, the controller 32 will adjust the electric push rod 3 to change the height of the moving frame 4, or adjust it through the adaptive extension and retraction of the first reset spring 19 in the telescopic assembly to ensure that the contact pressure between the testing head 9 and the surface of the carrier tape is moderate. The testing head 9 and the pressure sensor 7 of this testing mechanism have been carefully selected and calibrated to detect protrusions with a height of less than 0.05 to 0.08 mm, which meets the current requirements for the sensitivity and accuracy of protrusion detection on the surface of the carrier tape. This effectively avoids the impact of protrusions on the surface of the carrier tape on the downstream customer's tape packaging production, and prevents problems such as poor sealing and tape jamming that reduce production efficiency. When there are bumps on the carrier tape surface, the detection head 9 is squeezed, the pressure sensor 7 will detect the pressure change and transmit the signal to the controller 32. The controller 32 will then issue a corresponding prompt signal and resume operation after the detection is completed.

[0021] The engaging assembly includes an L-shaped engaging block 23, a push block 24, and a second return spring 25. A second mounting groove 26 is provided on the connector 6. One end of the second return spring 25 is installed in the second mounting groove 26, and the other end of the second return spring 25 is connected to the L-shaped engaging block 23. The push block 24 is fixedly connected to the L-shaped engaging block 23. An engaging groove 27 is provided on the moving frame 4. The L-shaped engaging block 23 passes through the second mounting groove 26 and engages in the engaging groove 27. For the installation of the detection components, push the push block 24 to compress the second return spring 25, so that the L-shaped locking block 23 moves completely into the second mounting slot 26. Then, connect the connector 6 to the moving frame 4. After releasing the push block 24, the L-shaped locking block is locked into the locking slot 27 on the moving frame 4 under the action of the second return spring 25, thus completing the installation of the detection components. According to the actual detection requirements, several detection components can be installed on the moving frame 4, and the distance between the connectors 6 can be adjusted to adapt to carrier tapes of different widths. The limiting mechanism includes a fixed frame 28, two telescopic rods 29, two third return springs 30, and two pulleys 31. The fixed frame 28 is mounted on the bidirectional electric slide rail 5. The third return springs 30 are sleeved on the outside of the telescopic rods 29. The two ends of the third return springs 30 and the telescopic rods 29 are respectively connected to the fixed frame 28 and the pulleys 31.

[0022] The bidirectional electric slide rail 5 drives the limiting mechanism to move as a whole, enabling the device to adapt to carrier belts of different widths. At the same time, under the elastic force of the third return spring 30, the telescopic rod 29 will extend and retract, causing the pulley 31 to always keep in contact with both sides of the carrier belt, thereby limiting the lateral displacement of the carrier belt during transmission and ensuring the accuracy of the detection position.

[0023] In the above embodiment, a controller 32 is fixedly installed on the support frame 2. The controller 32 is electrically connected to the electric push rod 3, the bidirectional electric slide rail 5, the pressure sensor 7 and the drive motor 11.

[0024] It should be noted that the specific models and specifications of the controller 32, electric push rod 3, bidirectional electric slide rail 5, pressure sensor 7 and drive motor 11 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
