Description

Technical Field

[0001] This utility model relates to the field of capacitor manufacturing technology, and in particular to a rapid detection device for tape and reel dimensions. Background Technology

[0002] Tape and reel capacitors refer to capacitors packaged in tape and reel form, which facilitates automated production. During the production process, multiple capacitors are automatically bonded to the carrier tape through their respective lead structures, and the multiple capacitors are arranged sequentially and spaced apart along the length of the carrier tape. In this arrangement, the carrier tape can protect the lead structure of the capacitors and prevent multiple capacitors from being damaged by friction and collision.

[0003] After the production of taped capacitors is completed, the quality manager needs to conduct random inspections to check whether the lead spacing between the two lead structures of the capacitor and the lead height from the capacitor sealing surface to the carrier tape are consistent, in order to ensure that the taped capacitors meet the production specifications. Currently, the inspection of taped capacitors mainly relies on manual inspection by inspectors using calipers, which is inefficient and has low accuracy. Furthermore, different operating techniques of different inspectors or inconsistent force control by the same inspector may lead to inaccurate measurement data, ultimately resulting in incorrect product judgment. There is a problem of incorrectly classifying qualified and unqualified products. If qualified products are judged as unqualified, it will inevitably lead to waste and increase production costs. If unqualified products are judged as qualified, it will affect the user's use. Utility Model Content

[0017] The beneficial effects of this utility model are as follows: The rapid detection device for tape and reel dimensions provided by this utility model has a detection component on the substrate. The detection component includes two spaced lead slots, and a positioning protrusion is formed between the two lead slots. The width of the positioning protrusion is adapted to the spacing between the two lead structures of the capacitor. By placing the two lead structures of the tape and reel capacitor into the two lead slots and observing whether the two lead structures of the tape and reel capacitor can enter the two lead slots, it is possible to directly obtain whether the spacing between the two lead structures of the tape and reel capacitor meets the requirements. The length of the positioning protrusion is adapted to the spacing between the capacitor sealing surface and the supporting tape. By placing the two lead structures of the tape and reel capacitor into the two lead slots, it is possible to directly obtain whether the spacing between the two lead structures of the tape and reel capacitor meets the requirements. Within the two lead slots, by observing whether the positioning protrusion can be directly placed between the capacitor sealing surface and the carrier tape, it is possible to determine whether the spacing between the capacitor sealing surface and the carrier tape of the taped capacitor meets the requirements.

Moreover, the dimensions of the positioning protrusion and the lead slots are fixed, which can ensure the consistency of each detection result, the reliability of the detection data, and avoid the problem of product judgment error, thus avoiding resource waste and reducing production costs.

[0035] This invention provides a rapid detection device for tape and reel dimensions that significantly improves detection efficiency.

[0036] The following is combined with Figures 1-5 The technical solution provided by this utility model will be described in more detail.

[0037] This utility model provides a rapid detection device for tape and reel dimensions, including a base 1, on which a detection component is disposed;

[0038] The detection component includes two spaced lead grooves 2, and a positioning protrusion 3 is formed between the two lead grooves 2. The width of the positioning protrusion 3 is adapted to the spacing between the two lead structures of the capacitor, and the length of the positioning protrusion 3 is adapted to the spacing between the capacitor sealing surface and the carrier tape.

[0039] The rapid detection device for tape and reel dimensions provided by this utility model has a detection component on the base 1. The detection component includes two spaced lead grooves 2, and a positioning protrusion 3 is formed between the two lead grooves 2. The width of the positioning protrusion 3 is adapted to the spacing between the two lead structures of the capacitor. By placing the two lead structures of the tape and reel capacitor into the two lead grooves 2, and observing whether the two lead structures of the tape and reel capacitor can enter the two lead grooves 2, it is possible to directly obtain whether the spacing between the two lead structures of the tape and reel capacitor meets the requirements.

[0040] The length of the positioning protrusion 3 is adapted to the spacing between the capacitor sealing surface and the carrier braid. By placing the two lead structures of the braided capacitor into the two lead grooves 2, and observing that the positioning protrusion 3 can be directly placed between the capacitor sealing surface and the carrier braid, it can be determined whether the spacing between the capacitor sealing surface and the carrier braid meets the requirements.

[0041] The rapid detection device for tape and reel dimensions provided by this utility model only requires placing the two lead structures of the tape and reel capacitor into the lead groove 2 to simultaneously obtain whether the spacing between the two lead structures of the capacitor and the spacing between the capacitor sealing surface and the supporting tape meet the requirements. This greatly improves the detection efficiency. Moreover, the dimensions of the positioning protrusion 3 and the lead groove 2 are fixed, which can ensure the consistency of each detection result, the reliability of the detection data, and the absence of product judgment errors, thus avoiding resource waste and reducing production costs. Furthermore, it has very low technical requirements for the detection personnel, allowing them to learn quickly and completely eliminating disputes caused by different measurement results from different personnel. This reduces unnecessary waste in the production process, greatly improves the testing efficiency and detection coverage of tape and reel product dimensions, and effectively prevents the outflow of unqualified products.

[0042] It is understandable that by setting two lead slots 2, the two lead structures of the capacitor can be placed in the two lead slots 2. The two lead slots 2 can limit the maximum distance and the minimum distance between the two lead structures, thereby ensuring that as long as the two lead slots 2 can be placed in the two lead slots 2, it can be confirmed that the distance between the two lead structures meets the requirements.

[0043] In some embodiments of this utility model, the width of the positioning protrusion 3 is the minimum distance between two adjacent lead wire structures.

[0044] In some of the embodiments of this utility model described above, since the spacing between the two lead structures has a certain tolerance range, as long as it is within the set range, it can be said that the spacing between the two lead structures meets the requirements.

[0045] Therefore, the width of the positioning protrusion 3 is the same as the minimum distance between two adjacent lead structures. The width of the positioning protrusion 3 can be used to directly confirm whether the minimum distance between the two lead structures meets the requirements.

[0046] In some embodiments of this utility model, the distance between the two outer sidewalls of the two lead grooves 2 that are far apart from each other is the maximum value of the distance between two adjacent lead structures.

[0047] In some embodiments of the present invention described above, the distance between the two outer sidewalls of the two lead slots 2 that are far apart from each other is the maximum value of the distance between two adjacent lead structures, thereby ensuring that as long as the two lead structures can be placed in the two lead slots 2, it can be said that the distance between the two lead structures meets the requirements, the detection can be completed quickly, and the detection accuracy and efficiency can be guaranteed.

[0048] In some embodiments of this utility model, the detection component further includes a positioning post 4, which is disposed on one side of the positioning protrusion 3 and is adapted to the positioning hole on the bearing tape.

[0049] In some embodiments of this utility model described above, the detection component further includes a positioning post 4, which is disposed on one side of the positioning protrusion 3. The positioning post 4 is adapted to the positioning hole on the carrier tape. During detection, the positioning hole on the carrier tape is fixed on the positioning post 4, and then the tape capacitor is placed downwards. The two lead structures of the tape capacitor can be placed into the lead groove 2. If the distance between the two lead structures is too large or too small, the two lead structures cannot be placed into the two lead grooves 2. If the gap between the capacitor sealing surface and the carrier tape is too large or too small, it cannot pass through the positioning protrusion 3. Thus, the detection can be completed quickly and efficiently, improving detection efficiency and ensuring detection quality.

[0050] It should be noted that the positioning post 4 is adapted to the positioning hole on the bearing tape, and the positioning post 4 is located on one side of the positioning protrusion 3 along its length, that is, the positioning post 4 is located between the two lead grooves 2 of the base 1.

[0051] In some embodiments of this utility model, the distance between the positioning post 4 and the positioning protrusion 3 is the same as the distance between the positioning hole and the capacitor sealing surface.

[0052] In some of the embodiments of this utility model described above, the distance between the positioning post 4 and the positioning protrusion 3 is the same as the distance between the positioning hole and the capacitor sealing surface. This ensures that after the positioning hole of the tape capacitor is aligned with the positioning post 4, the two lead wire structures of the tape capacitor can correspond exactly to the two lead wire slots 2, thereby ensuring improved detection efficiency and rapid completion of the detection.

[0053] In some embodiments of this utility model, the base 1 is further provided with a bearing boss 7, which is disposed on the second side of the positioning protrusion 3, and the second side is the side away from the positioning post 4.

[0054] In some embodiments of the present invention described above, a bearing boss 7 is provided on the substrate 1. The bearing boss 7 is located on the side away from the positioning post 4. The bearing boss 7 is used to support the boss plug of the tape capacitor.

[0055] It should be noted that tape and reel capacitors are generally provided with a platform plug and a boss plug. When the tape and reel capacitor is provided with a platform plug, the platform plug is flush with the sealing surface of the tape and reel capacitor, and in this case, there is no need to provide a supporting boss 7. When the tape and reel capacitor is provided with a boss plug, the boss plug will protrude towards the sealing surface of the tape and reel capacitor. In this case, the supporting boss 7 supports the boss plug, thereby ensuring that the tape and reel capacitor is more stable.

[0056] In some embodiments of this utility model, a capacitor limiting block 5 is provided on the base 1, and the capacitor limiting block 5 is located on the side of the bearing boss 7 away from the positioning post 4.

[0057] In some of the embodiments of this utility model described above, a capacitor limiting block 5 is provided on the substrate 1, and a tape capacitor placement area is formed between the capacitor limiting block 5 and the bearing boss 7. During testing, after the two lead structures of the tape capacitor are placed into the lead groove 2, the main body of the tape capacitor enters the capacitor placement area, which can effectively protect the tape capacitor and the lead structure and avoid deformation of the lead structure.

[0058] In some embodiments of this utility model, a tape limiting block 6 is also provided on the base 1, and the tape limiting block 6 is located on the side of the positioning post 4 away from the positioning protrusion 3.

[0059] In some embodiments of this utility model, a tape limiting block 6 is provided on the substrate 1, and a tape placement area is formed between the tape limiting block 6 and the positioning protrusion 3. During testing, after the positioning hole on the tape of the tape capacitor corresponds to the positioning post 4, the tape is placed in the tape placement area. Then, the capacitor body of the tape capacitor is placed in the capacitor placement area. By observing that the two lead structures can be inserted into the lead groove 2 and the positioning protrusion 3 can pass through the tape and the capacitor sealing surface, the test is completed.

[0060] In some embodiments of this utility model, the detection components are provided in multiple groups; and / or, the detection components are provided in 25 groups.

[0061] In some embodiments of this invention described above, multiple sets of detection components can simultaneously complete multiple tests, significantly improving testing efficiency. Specifically, the detection components are provided in 25 sets, enabling simultaneous testing of a tape-and-reel capacitor consisting of 25 individual capacitors. This significantly improves efficiency and effectively ensures that the tape-and-reel capacitor is not affected during the testing process, avoiding potential damage and guaranteeing testing quality.

[0062] In some embodiments of this utility model, multiple sets of the detection components extend sequentially along the width direction of the positioning protrusion 3.

[0063] In some of the embodiments of this utility model described above, multiple sets of detection components extend sequentially along the width direction of the positioning protrusion 3, and the detection of the tape capacitor is completed simultaneously by multiple sets of detection components, which greatly improves efficiency.

[0064] Example 1:

[0065] The present invention provides a rapid detection device for tape and braid dimensions, comprising a base 1 on which 25 sets of detection components are provided; each set of detection components includes two spaced lead grooves 2, and a positioning protrusion 3 is formed between the two lead grooves 2. The width of the positioning protrusion 3 is adapted to the spacing between the two lead structures of the capacitor, and the length of the positioning protrusion 3 is adapted to the spacing between the capacitor sealing surface and the carrier tape. The 25 sets of detection components extend sequentially along the width direction of the positioning protrusion 3.

[0066] Specifically, since the distance between the two lead structures meets the requirements within a reasonable tolerance range, the width of the positioning protrusion 3 is the minimum distance between two adjacent lead structures. The distance between the two outer sidewalls of the two lead grooves 2 that are far apart from each other is the maximum distance between two adjacent lead structures.

[0067] Furthermore, the detection component also includes a positioning post 4, which is disposed on the base 1 and located on the first side of the positioning protrusion 3. The positioning post 4 is adapted to the positioning hole on the bearing tape, and the distance between the positioning post 4 and the positioning protrusion 3 is the same as the distance between the positioning hole and the capacitor sealing surface.

[0068] It is understood that the 25 sets of detection components include 25 sets of positioning posts 4, each set of positioning posts 4 being matched with every two spaced lead wire grooves 2.

[0069] During the testing of tape and reel capacitors, the 25 positioning holes on the carrier tape are respectively fitted onto the 25 sets of positioning posts 4, and then several capacitor bodies are placed on the base in sequence. The test can be completed by observing whether the positioning protrusions 3 can be exposed. If any positioning protrusion cannot be exposed, it means that the lead structure corresponding to the positioning protrusion 3 or the size between the capacitor sealing surface and the carrier tape does not meet the requirements, and the test can be completed quickly.

[0070] Furthermore, the substrate 1 is also provided with a tape limiting block 6 and a capacitor limiting block 5. The tape limiting block 6 is located on the side of the positioning post 4 away from the positioning protrusion 3, and the capacitor limiting block 5 is located on the side of the bearing protrusion 7 away from the positioning post 4.

[0071] Specifically, the tape and reel size rapid detection device provided by this utility model is made of copper material, and the edge of the lead groove 2 is chamfered to facilitate the lead wire structure entering the lead groove 2.

[0072] Example 2:

[0073] The difference between this embodiment 2 and embodiment 1 is that the base 1 is further provided with a bearing boss 7, which is located on the second side of the positioning protrusion 3, and the second side is the side away from the positioning post 4.
