Description

Technical Field

[0001] The present invention relates to the field of material transfer, and particularly to a transfer jig and a transfer method for MLCCs. Background Art

[0002] MLCC (Multi-layer Ceramic Capacitors) is formed by laminating ceramic dielectric films printed with electrodes (inner electrodes) in a staggered manner, sintering them at a high temperature once to form a ceramic chip, and then sealing metal layers (outer electrodes) at both ends of the chip, thus forming a monolithic-like structure.

[0003] Due to the small size of the MLCC structure, when it is necessary to regularly transfer MLCCs to a material carrier tray, either manually place each MLCC into the material receiving grooves of the material carrier tray one by one, or pour a large number of MLCCs onto the material carrier tray and then use a brush to sweep away the MLCCs that are not placed in the material receiving grooves or the excess MLCCs. Both of the above methods are time-consuming and laborious, and when using the latter method, the MLCCs may also spill outside the material carrier tray, causing loss or damage to the MLCCs.

[0004] Therefore, it is necessary to provide a new transfer jig and a transfer method for MLCCs to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a transfer jig and a transfer method for MLCCs, which can batch transfer the MLCCs stored in a storage container to the material receiving platform of a material carrier tray, and the MLCCs are placed in the receiving slots in a preset posture, avoiding manually transferring each MLCC to the material receiving platform one by one and improving the transfer efficiency.

[0006] To achieve the above purpose, the present invention provides a transfer jig for MLCCs. The MLCC is in a cuboid-like shape. The transfer jig includes:

[0007] A material carrier tray, which includes a chassis and a material receiving platform protruding from the chassis. The material receiving platform is provided with receiving slots for placing MLCCs.

[0009] After the material receiving platform of the material carrier tray is fitted into the material guiding opening, the MLCCs in the accommodating chamber can enter the accommodating slot.

[0010] Optionally, a plurality of the material receiving platforms are provided and arranged horizontally on the material carrier tray, and the container wall is provided with the same number and the same arrangement of the material guiding openings as the material receiving platforms;

[0011] A recessed portion is formed between two adjacent material receiving platforms, and a blocking portion is formed on the container wall portion between two adjacent material guiding openings;

[0012] When the material receiving platforms of the material carrier tray are respectively fitted into the corresponding material guiding openings, the blocking portion is fitted into the recessed portion.

[0013] Optionally, one of the bottom of the recessed portion and the top of the blocking portion is provided with a velcro flocked surface, and the other is provided with a velcro hook surface;

[0014] When the blocking portion is fitted into the recessed portion, the velcro flocked surface and the velcro hook surface are mutually adhered.

[0015] Optionally, the MLCC is in a shape of a quasi-rectangular parallelepiped. When the material receiving platform of the material carrier tray is fitted into the material guiding opening, the gap width between the material receiving platform and the material guiding opening is smaller than the length of the shortest side of the MLCC.

[0016] Optionally, the container wall includes a flat wall, the flat wall includes a material guiding area and a non-material guiding area, the material guiding opening is provided in the material guiding area of the flat wall, and the non-material guiding area is used for allowing the MLCC to move to the material guiding area and receiving the MLCC that has not entered the material receiving platform in the material guiding area;

[0017] When the material receiving platform of the material carrier tray is fitted into the material guiding opening, the chassis of the material carrier tray covers and closely adheres to the material guiding area.

[0018] Optionally, the material guiding area and the non-material guiding area are respectively provided at opposite ends of the flat wall.

[0019] Optionally, the depth of the accommodating slot is greater than or greater than or equal to the thickness of the MLCC when the MLCC is placed in the accommodating slot.

[0020] Optionally, the protruding height of the material receiving platform on the chassis is the same as the thickness of the portion of the container wall where the material guiding opening is provided;

[0021] When the material receiving platform of the material carrier tray is fitted into the material guiding opening, the top wall of the material receiving platform and the inner wall of the container wall are in the same plane.

[0027] (4) Tilt and shake the material carrier tray and the storage container so that the MLCCs enter the accommodation slots of the material receiving platform in a flat laying posture;

[0028] (5) Tilt the material carrier tray and the storage container so that the MLCCs that have not entered the accommodation slots move away from the material receiving platform;

[0029] Repeat steps (4)-(5) until the MLCC transfer work is completed, and then separate the material carrier tray and the storage container.

[0030] The accommodation chamber of the storage container of the present invention can store MLCCs in a quasi-rectangular parallelepiped shape. A material guiding opening communicating with the accommodation chamber is provided on the container wall of the storage container. A material receiving platform protrudes from the bottom plate of the material carrier tray.

After the material receiving platform of the material carrier tray is fitted into the material guiding opening, by performing operations such as flipping, shaking, and tilting while maintaining the fitted state of the material carrier tray and the storage container, the MLCCs in the accommodation chamber can enter the accommodation slots. Since the width of the accommodation slots is greater than or greater than or equal to the length of the shortest side of the MLCC and less than the lengths of the other sides of the MLCC except the shortest side, the posture of the MLCC placed in the accommodation slots is restricted, and under the action of tilting and shaking, the MLCCs are placed in the accommodation slots in a preset posture, thereby realizing the transfer of the MLCCs to the material carrier tray and presenting a regular placement posture, avoiding the need to manually transfer the MLCCs to the material carrier tray one by one, saving time and effort, improving efficiency, and being easy to operate.

[0039] In order to explain in detail the technical content, structural features, achieved purposes and effects of the present invention, the following is described in detail in combination with the embodiments and with reference to the drawings.

[0040] Please refer to Figures 1 to 3 and Figures 6 to 7 , to achieve the above object, the present invention discloses a transfer jig for MLCC. The MLCC is in the shape of a quasi-rectangular parallelepiped. The transfer jig includes a material carrier tray 1 and a storage container 2. Among them, the material carrier tray 1 includes a chassis 11 and a material receiving table 12 protruding from the chassis 11. The material receiving table 12 is provided with a receiving slot 13 for placing the MLCC. The width of the receiving slot 13 is greater than or equal to the length of the shortest side of the MLCC and less than the lengths of the other sides of the MLCC except the shortest side. The storage container 2 includes a container wall 21 and a receiving chamber 24 formed by the container wall 21. The receiving chamber 24 is used for storing the MLCC. A material guiding opening 22 communicating with the receiving chamber 24 is formed on the container wall 21. The material guiding opening 22 is used for fitting the material receiving table 12 of the material carrier tray 1. After the material receiving table 12 of the material carrier tray 1 is fitted in the material guiding opening 22, the MLCC in the receiving chamber 24 can enter the receiving slot 13.

[0041] The accommodating chamber 24 of the storage container 2 of the present invention can store MLCCs. A material guiding opening 22 communicating with the accommodating chamber 24 is formed on the container wall 21 of the storage container 2. A material receiving platform 12 protrudes from the bottom plate 11 of the material carrier tray 1. The material receiving platform 12 is provided with a receiving slot 13. The material receiving platform 12 can be fitted into the material guiding opening 22. After the material receiving platform 12 of the material carrier tray 1 is fitted into the material guiding opening 22, by performing operations such as flipping, shaking, and tilting while maintaining the fitted state of the material carrier tray 1 and the storage container 2, the MLCCs in the accommodating chamber 24 can enter the receiving slot 13. Since the width of the receiving slot 13 is greater than or greater than or equal to the length of the shortest side of the MLCC and less than the lengths of the other sides of the MLCC except the shortest side, the posture of the MLCC placed in the receiving slot 13 is restricted. And under the action of tilting and shaking, the MLCCs are placed in the receiving slot 13 in a preset posture, so as to realize the transfer of the MLCCs to the material carrier tray 1 and present a regular placement posture, avoiding the need to manually transfer the MLCCs to the material carrier tray 1 one by one, saving time and effort, improving efficiency, and being easy to operate.

[0042] Specifically, in some embodiments, the MLCC, as Figure 3 shown, is in a shape similar to a cuboid. Its shortest side is the bottom edge of the side surface of the MLCC, and the other sides refer to the sides with lengths different from the shortest side.

[0043] When the MLCC enters the receiving slot 13, the MLCC can only contact the bottom surface of the receiving slot 13 with the side surface and the bottom surface where the shortest side is located, and the shortest side needs to be horizontally arranged in the receiving slot 13. That is to say, the MLCC can lie flat in the receiving slot 13 with the bottom surface or stand upright in the receiving slot 13 with the side surface. By tilting and shaking the transfer jig, the MLCCs standing upright in the receiving slot 13 can be set in a flat placement posture.

[0044] Please refer to Figure 1 and Figure 7 , specifically, when the material receiving platform 12 of the material carrier tray 1 is fitted into the material guiding opening 22, the gap width between the material receiving platform 12 and the material guiding opening 22 is less than the length of the shortest side of the MLCC, so as to prevent the MLCCs from falling from the accommodating chamber 24 of the storage container 2 onto the bottom plate 11 of the material carrier tray 1. Preferably, when the material receiving platform 12 of the material carrier tray 1 is fitted into the material guiding opening 22, the gap width between the material receiving platform 12 and the material guiding opening 22 can be as small as possible so that the material receiving platform 12 and the material guiding opening 22 are in close contact.

[0045] Furthermore, if the cross-section of the material receiving platform 12 and the shape of the material guiding opening 22 are both rectangular, the difference between the width of the material guiding opening 22 and the width of the material receiving platform 12 can be set to be less than the length of the shortest side of the MLCC, and the difference between the length of the material guiding opening 22 and the length of the material receiving platform 12 can be set to be less than the length of the shortest side of the MLCC.

[0046] Specifically, the container wall 21 of the storage container 2 can be made of a transparent material, which is convenient for the operator to directly observe the state and position of the MLCCs inside the storage container 2. Also, the friction between the inner wall of the container wall 21 and the MLCCs should be as small as possible. Therefore, the container wall 21 can be a transparent acrylic board or transparent glass.

[0047] It can be understood that the storage container 2 can be in the shape of a cuboid, or in the shape of other polyhedrons, or even in an irregular shape, as long as there is a container wall 21 that is a planar wall 222. This application does not make specific restrictions here.

[0048] Please refer to Figure 2 and Figure 4 , preferably, the storage container 2 is in the shape of a cuboid, which is easy to place on the operating table. A planar wall 222 of the storage container 2 includes a material guiding area 212 and a non-material guiding area 211. The material guiding opening 22 is provided in the material guiding area 212 of the planar wall 222. The non-material guiding area 211 is used for the MLCCs to move to the material guiding area 212 and to receive the MLCCs that have not entered the material receiving table 12 in the material guiding area 212. When the material receiving table 12 of the material carrier 1 is fitted into the material guiding opening 22, the chassis 11 of the material carrier 1 covers and closely adheres to the material guiding area 212. When the storage container 2 and the material receiving table 12 are turned over so that the material receiving table 12 faces upward and the material guiding opening 22 faces downward, the MLCCs are gathered in the non-material guiding area 211, and then tilted toward the material guiding area 212 so that the MLCCs move to the material guiding area 212 and enter the receiving slot 13. After the action of guiding the MLCCs into the receiving slot 13 is completed, it is tilted toward the non-material guiding area 211 to make the MLCCs that have not entered the receiving slot 13 in the material guiding area 212 return to the non-material guiding area 211 again.

[0049] It can be understood that the shape of the material guiding area 212 is the same as that of the material carrier 1, and when the material receiving table 12 of the material carrier 1 is fitted with the material guiding opening 22, the chassis 11 can cover and fit the material guiding area 212, thereby preventing the MLCCs from falling outside the transfer jig during the transfer process.

[0050] Furthermore, the material guiding area 212 and the non-material guiding area 211 are respectively provided at opposite ends of the planar wall 222. When performing the transfer operation on the MLCCs, the transfer jig can be directly tilted toward one of the two ends of the planar wall 222 to make the MLCCs move to the material guiding area 212 or the non-material guiding area 211.

[0051] Please refer to Figure 6 and Figure 7, specifically, a plurality of material receiving platforms 12 are provided and arranged horizontally on the material carrier 1, and the container wall 21 is provided with material guiding openings 22 having the same number and the same arrangement as the material receiving platforms 12; a recessed portion 14 is formed between two adjacent material receiving platforms 12, and a blocking portion 23 is formed on the portion of the container wall 21 between two adjacent material guiding openings 22; when the material receiving platforms 12 of the material carrier 1 are respectively fitted into the corresponding material guiding openings 22, the blocking portion 23 is fitted into the recessed portion 14. The shape and size of the material receiving platform 12 match those of the corresponding material guiding opening 22. Generally, the cross-section of the material receiving platform 12 and the material guiding opening 22 can be rectangular.

[0052] Please refer to Figure 4 , Figure 6 and Figure 8 , in some embodiments, one of the bottom of the recessed portion 14 and the top of the blocking portion 23 is provided with a velcro surface 5, and the other is provided with a velcro hook surface 6; when the blocking portion 23 is fitted into the recessed portion 14, the velcro surface 5 and the velcro hook surface 6 are attached to each other. By providing velcro as the fixing device after the material receiving platform 12 and the material guiding opening 22 are fitted, when the transfer jig is tilted or shaken, it is not necessary for the operator to always hold the material carrier 1 and the storage container 2 by hand, and it is also easy to separate after the MLCC transfer is completed.

[0053] It can be understood that the bottom of the recessed portion 14 is part of the chassis 11 of the material carrier 1.

[0054] Please refer to Figure 5 , in some embodiments, a feed port 216 is formed on the container wall 21, a door body 215 movably connected to the container wall 21 is provided at the feed port 216, and the size of the feed port 216 is larger than that of the material guiding opening 22. The MLCC can be introduced into the accommodation chamber 24 of the storage container 2 through the feed port 216, rather than through the material guiding opening 22.

[0055] Please refer to Figure 6 and Figure 7 , further, the depth of the accommodation slot 13 is greater than or greater than or equal to the thickness of the MLCC when placed in the accommodation slot 13, so that when the MLCC is placed in the accommodation slot 13, it is not easily separated from the accommodation slot 13 due to the shaking or tilting of the operator. Preferably, the depth of the accommodation slot 13 can be set to be the same as the thickness of the MLCC when placed in the accommodation slot 13 to avoid stacking of the MLCC in the accommodation slot 13.

[0056] Please refer to Figure 1 and Figure 7, in some embodiments, the height of the material receiving platform 12 on the chassis 11 is the same as the thickness of the part of the container wall 21 where the material guiding opening 22 is provided; when the material receiving platform 12 of the material carrier 1 is fitted into the material guiding opening 22, the top wall 121 of the material receiving platform 12 is in the same plane as the inner wall 231 of the container wall 21. When the top wall 121 of the material receiving platform 12 is in the same plane as the inner wall 231 of the container wall 21, when transferring the MLCC, it is possible to avoid the situation of jamming the MLCC due to the unevenness between the top wall 121 of the material receiving platform 12 and the inner wall 231 of the container wall 21.

[0057] Please refer to Figures 1 to 8 , the present invention also provides a method for transferring MLCC, using the transfer jig as described above to transfer the MLCC, including:

[0058] (1) Place a number of MLCCs in the accommodation chamber 24 of the storage container 2;

[0059] (2) Orient the material guiding opening 22 of the storage container 2 upward so that the MLCC is located at the bottom of the accommodation chamber 24;

[0060] (3) Fit the material receiving platform 12 of the material carrier 1 into the material guiding opening 22, and then turn over the material carrier 1 and the storage container 2 so that the material guiding opening 22 faces downward and the material receiving platform 12 faces upward;

[0061] (4) Tilt and vibrate the material carrier 1 and the storage container 2 so that the MLCC enters the accommodation slot 13 of the material receiving platform 12 in a flat laying posture;

[0062] (5) Tilt the material carrier 1 and the storage container 2 so that the MLCC that has not entered the accommodation slot 13 moves away from the material receiving platform 12;

[0063] Repeat steps (4)-(5) until the MLCC transfer work is completed, then separate the material carrier 1 and the storage container 2.

[0064] The above-disclosed are only the preferred examples of the present invention and cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention all fall within the scope covered by the present invention.
