Description

Technical Field

[0001] This utility model relates to the field of chip capacitor feeding technology, and in particular to a novel MLCC feeding device. Background Technology

[0002] In the testing and sorting process of MLCCs (multilayer ceramic capacitors), the loading stage is a key step in achieving automated production. Currently, mainstream manufacturers generally adopt a structure combining multiple tangential tracks with vacuum adsorption to guide the MLCCs into the slots on the test tray. This structure typically includes a vacuum base, a test tray, and eight independently set tangential tracks. During the rotation of the test tray, the MLCCs are precisely placed into the slots through the tangential engagement between the slots and the tracks, and with the help of vacuum adsorption, thus completing the entire process of loading, testing, and sorting.

[0003] However, this traditional structure has many limitations. First, due to the large number of independent tracks, the precision requirements for component machining are extremely high, leading to a significant increase in manufacturing costs. Second, each track needs to be equipped with a corresponding sensor for material detection, which not only increases system complexity and equipment costs, but also, due to the irregular movement of materials, is prone to problems such as false detection, material shortage, or blockage, affecting the stability and efficiency of equipment operation. In addition, the traditional structure lacks an effective material dispersion and limiting cleaning mechanism, which easily causes MLCC accumulation and jamming, further reducing the success rate of material feeding.

A wedge block is fixedly provided on one side inside the sector-shaped block, and an air knife is provided on the wedge block. An air knife is provided on the other side inside the sector-shaped block.

[0005] Preferably, the wedge is fixed to the sector block by bolts, and the wedge forms a 25° angle with the bottom of the sector block.

[0006] Preferably, the air knife is composed of several air holes opened on the wedge block, with the air holes facing the test plate, for blowing away the accumulated MLCC material.

[0014] This utility model provides a novel MLCC feeding device, which, compared with the prior art:

[0015] 1. This utility model adopts an innovative trackless structure design, which achieves efficient MLCC insertion through the synergistic action of air knives and scrapers, replacing the traditional multi-track vacuum adsorption structure. The device uses air knives one and two set inside the fan-shaped block to work together, combined with the limiting and cleaning functions of scrapers one and two, to effectively prevent material from accumulating too high and improve the uniformity of material distribution, thereby significantly improving the success rate of MLCC insertion. In addition, the design of the wedge block and the bottom of the fan-shaped block forming a 25° angle further optimizes the airflow direction, making it easier for MLCCs to follow the rotation of the test disc and improving the stability of feeding.

[0016] 2. The present invention has a simplified structure, which reduces the dependence on processing precision and avoids the high cost and high maintenance requirements brought about by the traditional 8 independent tangential track structure. At the same time, the material accumulation status in the sector block is monitored in real time by full-material optical fiber, and the start and stop of the feeder are automatically controlled to ensure that the material quantity is maintained within a reasonable range, thereby improving the degree of automation and operating efficiency.

[0027] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please refer to Figures 2 to 7 This utility model provides a novel MLCC feeding device, including a test plate 2, which is driven by a motor 4, which is a DD motor. A vacuum base 1 is installed on the lower side of the test plate 2, and several acupoints 3 are provided on the upper side of the test plate 2. The acupoints 3 adsorb MLCCs through the negative pressure provided by the vacuum base 1, ensuring that they will not shift or fall off during rotation.

[0029] A sector-shaped block 7 is set around the test tray 2. The inside of the sector-shaped block 7 is a hollow cavity used to accommodate the feeding-related functional components. The upper side of the sector-shaped block 7 is fixedly connected to the flipping arm 6. The flipping arm 6 is rotatably mounted on the base 5 via a rotating shaft. The base 5 is mounted on the large plate of the equipment, so that the entire sector-shaped block 7 and the test tray 2 assembly can be flipped 90 degrees and fixed through the flipping arm 6, which facilitates the quick disassembly, cleaning or replacement of the test tray 2.

[0030] A wedge 8 is provided on one side inside the sector block 7. The wedge 8 is fixedly connected to the sector block 7 by bolts, and its working surface forms a 25° angle with the bottom of the sector block 7. Several air holes are opened on the wedge 8 to form an air knife 9. The air holes are arranged facing the test plate 2 and are used to blow air onto the surface of the test plate 2 to disperse the accumulated MLCC material and make it evenly distributed, thereby improving the success rate of MLCC falling into the cavity 3.

[0031] On the other side inside the fan-shaped block 7, there is a second air knife 10 with its air blowing holes facing the notch 12 area of ​​the scraper 11. This is used to help blow off MLCCs that have not entered the cavity 3, and to prevent material accumulation from affecting subsequent feeding.

[0032] The fan-shaped block 7 is also equipped with a scraper 11. The scraper 11 is located between the air knife 9 and the air knife 2 10. Several notches 12 corresponding to the positions of the acupoints 3 are opened on its lower side to avoid MLCCs that have entered the acupoints and block excess materials that have not entered the acupoints. The scraper 11 can effectively prevent MLCCs that accidentally enter other areas from interfering with the subsequent testing and sorting process.

[0033] A scraper 2 13 is provided on the outer edge of the fan-shaped block 7. The scraper 2 13 is located on one side of the air knife 2 10 and is used to further scrape off MLCCs that have not fully entered the acupoint 3 or are stuck on the edge of the acupoint 3. In order to facilitate installation and replacement, the scraper 2 13 is fixed in the slot 15 opened on the side of the fan-shaped block 7 by plugging in, so as to achieve quick installation and removal.

[0034] In addition, the sector block 7 is equipped with a full-material optical fiber 14, which is located on one side of the scraper 11. It is used to monitor the material accumulation status inside the sector block 7 in real time. When the MLCCs accumulate to the sensing area of ​​the full-material optical fiber 14, the control system will automatically control the feeder to stop feeding to prevent material overflow. When the material decreases, the feeder will restart, thereby maintaining the stability of the number of MLCCs inside the sector block 7 and improving the level of automation control.

[0035] Compared with traditional feeding mechanisms ( Figure 1 (See schematic diagram of traditional feeding mechanism). This utility model abandons the traditional feeding structure that combines 8 independent tangential tracks with vacuum adsorption. It innovatively adopts a trackless design. Through the synergistic effect of structures such as air knife 19, air knife 20, scraper 11 and scraper 23, it achieves efficient and stable insertion of MLCCs into the cavity. This structure not only significantly reduces the requirements for the machining accuracy of parts and reduces the manufacturing and maintenance costs of equipment, but also improves the automation level and operational stability of the system through the setting of full-load optical fiber 14. It is suitable for the continuous and efficient production needs of MLCC testing and sorting machines.

[0036] In summary, MLCC material enters the test tray 2 through an external feeding system. Air knife 9 disperses the accumulated material through the air holes on the wedge block 8 to prevent excessive material accumulation and improve the uniformity of material distribution. The test tray 2 rotates under the drive of the DD motor, moving the cavity 3 to the material area. The negative pressure adsorption provided by the vacuum base 1 allows the MLCC to be stably inserted into the cavity. Scraper 11, in conjunction with its lower notch 12, blocks material that has not entered the cavity. Air knife 10 blows off excess material through the notch 12. Scraper 13 further removes MLCCs that have not been completely inserted into the cavity or are stuck at the edge of the cavity 3 to ensure accurate feeding. Full material fiber optic cable 14 monitors the material quantity in real time and automatically controls the start and stop of the feeder to maintain a stable material supply.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
