Abstract
Description
Technical Field
[0001] This utility model relates to the field of MLCC wafer arrangement technology, and in particular to an automatic device for MLCC wafer arrangement. Background Technology
[0002] MLCCs are among the most widely used passive components in modern electronic circuits, boasting advantages such as small size, large capacitance, and high stability. Their manufacturing process is extremely complex and precise, primarily involving: dielectric slurry preparation, casting, internal electrode printing, stacking, lamination, cutting, adhesive removal, sintering, end electrode coating, electroplating, and testing. The "layout" process, also known as "mounting" or "layout," specifically refers to the orderly placement of pre-sintered green ceramic blocks (tiny cubes formed after lamination and cutting) into specific positions on a sintering plate (or firing plate). This process is crucial in connecting the preceding forming process with the subsequent sintering process, and its quality and efficiency directly impact product yield, production efficiency, and production costs.
[0003] Currently, MLCCs typically require manual operation during wafer layout. This method is inefficient, with a limited number of wafers per person per day, which cannot meet the needs of modern large-scale production. Furthermore, it is easily affected by operator fatigue, skill level, and emotional fluctuations, making it difficult to maintain consistent placement, angle, and force, resulting in large fluctuations in product yield. Utility Model Content

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.
[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0024] Example 1
[0025] An automatic device for MLCC stacking, such as Figure 1-4 As shown, the device includes an adsorption sheet assembly, which includes a base 1. A support plate 16 is provided on the top of the base 1. A conveying assembly for conveying is provided on one side of the support plate 16. A support frame 7 is provided on the top of the base 1. An electric slide 8 is provided on one side of the support frame 7. A connecting frame 9 is provided on one side of the electric slide 8. A fixing plate 6 is provided at the bottom of the connecting frame 9. Several sets of columns are arranged sequentially at the bottom of the fixing plate 6. A connecting plate 26 is provided at the bottom of the columns. An electromagnet 20 is provided on the top of the connecting plate 26. Several sets of electromagnets 20 are arranged sequentially. An adsorption plate 19 is detachably provided at the bottom of the electromagnet 20. A feeding assembly for centralized feeding and a vibration assembly for vibration dispersion are provided on one side of the support plate 16.
[0026] In use, the MLCC material is fed into the feeding assembly and conveyed to the conveying assembly. During conveying, the MLCC material is vibrated by the vibration assembly to evenly disperse it and prevent accumulation that could affect adsorption and film formation. The electric slide 8 controls the movement of the connecting frame 9 and the fixing plate 6. Moving the fixing plate 6 moves the position of the connecting plate 26. Moving the connecting plate 26 away from the conveying assembly allows the adsorption plate 19 to be mounted on it. The adsorption plate 19 contains magnetic material; energizing the electromagnet 20 at the top of the connecting plate 26 generates magnetism, allowing the connecting plate 26 to adsorb and fix the adsorption plate 19 upon contact. After fixing, the adsorption plate 19 and the connecting plate 26 can be controlled to move to the conveying component. The MLCC material can be adsorbed by the magnetism of the adsorption plate 19. The MLCC material has a certain magnetism and will be attracted to the adsorption plate 19. By adsorbing it onto the adsorption plate 19, the wafer arrangement can be completed quickly, which can effectively improve efficiency. At the same time, no manual operation is required, which solves the problem of low manual efficiency and inability to complete large-scale production. It can also increase the accuracy of wafer arrangement and avoid fluctuations in yield. After the wafer arrangement is completed by adsorption, the adsorption plate 19 is controlled to move away from the conveying component and the power supply of the electromagnet 20 is disconnected, thereby releasing the fixation of the adsorption plate 19 and making it easy to remove it. After removal, it can be piled up and collected. After a large amount is collected, it can be transported to the sintering area for sintering treatment.
[0027] The conveying assembly includes a first motor compartment 24, which is mounted on one side of a support plate 16. Two sets of first output shafts 15 are connected to the output end of one side of the first motor compartment 24. One end of each first output shaft 15 is rotatably mounted through the support plate 16. Each first output shaft 15 has a pulley, through which a first conveyor belt 14 is mounted. A second motor compartment 25 is located on one side of the support plate 16. Two sets of second output shafts 18 are connected to the output end of one side of the second motor compartment 25. One end of each second output shaft 18 is rotatably mounted through the support plate 16. Each second output shaft 18 also has a pulley, through which a second conveyor belt 23 is mounted. Two sets of blocking frames 21 are located on one side of the support plate 16, their positions adapted to the first conveyor belt 14 and the second conveyor belt 23, respectively. A guide plate 10 is located on one side of the support plate 16, its position adapted to the first conveyor belt 14 and the second conveyor belt 23.
[0028] In operation, the motors in the first motor compartment 24 and the second motor compartment 25 are activated to control the rotation of the first output shaft 15 and the second output shaft 18. The rotation of the first output shaft 15 and the second output shaft 18 drives the pulleys, synchronously controlling the rotation of the first conveyor belt 14 and the second conveyor belt 23. MLCC material discharged by the unloading assembly falls onto the first conveyor belt 14, which then transports it. A set of blocking frames 21 blocks the MLCC material during transport, organizing the disordered material and ensuring it is evenly arranged and adjusted to a suitable angle. After arrangement and angle adjustment, the continuously transported MLCC material from the bottom layer will evenly flow from the arranged MLCC material. The MLCC materials pass through the conveyor belt, and the passing MLCC materials are relatively neat and have consistent angles. The guide plate 10 can assist in the conveying. The MLCC materials passing through a set of blocking frames 21 will slide off the guide plate 10 onto the second conveyor belt 23 for continued conveying. When the connecting frame 9 moves, the adsorption plate 19 can be moved to the second conveyor belt 23. The second conveyor belt 23 can convey the MLCC materials, and the other set of blocking frames 21 can block the MLCC materials. After blocking, the materials can be evenly arranged. After arrangement, the adsorption plate 19 can adsorb the neatly arranged MLCC materials. After adsorption, the MLCC materials can be arranged. After adsorption, the empty areas can be filled by the continuous conveying of the second conveyor belt 23, which facilitates the subsequent adsorption and arrangement.
[0029] The feeding assembly includes a fixed bracket 13, which is installed on the top of the support plate 16. A limit frame 12 is provided on one side of the fixed bracket 13, and a feeding funnel 11 is installed through the limit frame 12. The position of the feeding funnel 11 is adapted to the first conveyor belt 14.
[0030] When in use, the MLCC material that needs to be arranged can be poured into the feeding funnel 11. After pouring, it can be sent to the first conveyor belt 14 through the opening at the bottom of the feeding funnel 11. After the feeding is completed, the first conveyor belt 14 can be started to transport the material. The feeding funnel 11, together with its large opening at the top, makes feeding more convenient and faster.
[0031] The vibration assembly includes a speed-regulating motor 17, which is mounted on one side of the support plate 16. The output end of the speed-regulating motor 17 is connected to a mounting shaft 28. One end of the mounting shaft 28 is rotatably disposed through the support plate 16, and a cam 27 is provided on the mounting shaft 28.
[0032] In use, the size and position of the cam 27 are adapted to the first conveyor belt 14. The speed-regulating motor 17 can start and control the rotation of the mounting shaft 28 and the cam 27. The rotation of the cam 27 can cause the first conveyor belt 14 to vibrate. After the MLCC material is conveyed onto the first conveyor belt 14, it can be sorted by vibration. With the help of the blocking frame 21, the angle correction and arrangement can be completed quickly, making the arrangement of the sheets more convenient.
[0033] To facilitate the replacement of the adsorption plate 19, such as Figure 2 As shown, a support platform 22 is provided on the top of the base 1, and the size of the support platform 22 is adapted to the adsorption plate 19.
[0034] In use, the adsorption plate 19 can be moved to the support platform 22 by the connecting frame 9. After it is moved into place, the power supply of the electromagnet 20 is turned off, and the adsorption plate 19 with the plate arrangement completed can be placed on the support platform 22. After placement, it is easy to remove and collect. After removal, a new adsorption plate 19 can be placed on the support platform 22. After placement, the adsorption plate 19 can be easily adsorbed and fixed by the connecting plate 26.
[0035] To assist in the replacement of the adsorption plate 19, such as... Figure 1 , 2 As shown in Figure 4, a rotary motor 2 is installed on the top of the base 1. A rotary shaft 3 is connected to the output end of the rotary motor 2. A rotary frame 4 is installed on the rotary shaft 3. The rotary frame 4 is L-shaped. A gripping disc 5 is installed through the rotary frame 4. Several sets of mechanical grippers are installed at the bottom of the gripping disc 5.
[0036] In use, the position of the gripping disc 5 can be adjusted by starting the rotary motor 2 to control the rotation of the rotating shaft 3 and the rotating frame 4. By controlling the rotation of the gripping disc 5, the two sets of gripping discs 5 can be moved synchronously. The mechanical gripper of one set of gripping discs 5 can grip and fix the adsorption plate 19 to be replaced. The other set of gripping discs 5 can grip the adsorption plate 19 that has been arranged on the support platform 22. After that, by rotating the gripping disc 5 to change its position, the adsorption plate 19 to be replaced can be moved to the support platform 22. At the same time, the adsorption plate 19 that has been arranged can be transferred from the support platform 22. After the transfer, the gripping and fixing can be released to facilitate its stacking and collection. Releasing the mechanical gripper of the other set of gripping discs 5 can lower the adsorption plate 19. After being lowered, the adsorption plate 19 falls on the support platform 22, which facilitates the movement of the connecting plate 26 for adsorption and fixing. The transfer and replacement of the adsorption plate 19 can be completed automatically without manual operation, thereby effectively increasing the arrangement efficiency.
[0037] Example 2
[0038] To increase the frequency and effect of vibration, refer to... Figure 3 An automatic device for MLCC stacking is provided. Compared with embodiment 1, this embodiment has the following improvements: the cam 27 is arranged in a circular pattern with four sets of protrusions, and the corners of the protrusions are provided with arc-shaped curved surfaces.
[0039] During use, the four sets of protrusions around the cam 27 can increase the vibration frequency and effect of the first conveyor belt 14 when it rotates. The arc-shaped surface can reduce the friction between the cam and the first conveyor belt 14, thereby effectively extending the service life and greatly reducing wear.
