DETAILED DESCRIPTION

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0044] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0045] Reference Figure 1-4 An embodiment of the present invention provides a sealing device, comprising a base 1, and a workpiece fixing mechanism and a scraping mechanism provided on the base 1, wherein the scraping mechanism has a leveling mechanism. Specifically, the workpiece fixing mechanism comprises the following parts:

[0046] A lifting portion 2 is longitudinally and movably disposed on the base 1;

[0047] The first support portion 3 maintains a horizontal sliding connection with the lifting portion 2, such as by a first slide rail mechanism 6;

[0048] The adsorption part 4 is horizontally rotatably connected to the first support part 3, and the adsorption part 4 is used to connect to the product placement plate (JIG plate);

[0049] The first touch portion 5 is used for holding by a human hand and is movably connected to the first support portion 3 and is in transmission cooperation with the adsorption portion 4;

[0050] Based on the above, during the sealing process, when the device places the capacitor evenly on the product placement tray, the product placement tray is sucked by the adsorption part 4, and by manipulating the first touch part 5, the adsorption part 4 can be rotated horizontally under the transmission action, so that the adsorption side of the adsorption part 4 is facing downward, and when the copper paste tray on the scraping mechanism is located below, the first support part 3 moves down, and the capacitor contacts the paste material, thereby completing the sealing; compared with the prior art, in the utility model, the rotation of the adsorption part 4 can be controlled by hand, so it is more flexible in direction control, so that multiple capacitors can better contact with the paste material, thereby ensuring the sealing quality; in the utility model, the first touch part 5 can adopt a push rod structure, which is convenient for manual holding and manipulation.

[0051] Further, refer to Figure 1 The first support portion 3 is also provided with a second touch portion 7, which is a push rod structure. The second touch portion 7 allows for better manual force application when manipulating the movement of the first support portion 3.

[0052] Further, refer to Figure 1 The action direction of the first slide rail mechanism 6 is parallel to the rotation axis of the adsorption part 4, so that when the adsorption platform is manually controlled to move back and forth, it is not easy to affect the stability of the adsorption part 4, thereby further ensuring the quality of the end sealing.

[0053] Further, refer to Figure 1-4 The adsorption part 4 includes a vacuum adsorption platform 402, which is equipped with a vacuum control valve 401. Specifically, the vacuum control valve 401 is fixedly set on the lifting part 2 and located below the first support part 3, so as to be easy to touch by human hands.

[0054] Further, refer to Figure 1-4Regarding the transmission method, specifically, a gear 8 is fixedly provided on the vacuum adsorption platform 402, which maintains a coaxial axis with the rotation direction of the vacuum adsorption platform 402. A rack 9 is slidably provided on the first support portion 3 and meshes with the gear 8. The first touch portion 5 is connected to the rack 9. When the first touch portion 5 moves, the gear 8 is driven to rotate through the rack 9 to complete the adjustment of the direction of the vacuum adsorption platform 402. This transmission method can fully ensure the accuracy of the direction adjustment process of the vacuum adsorption platform 402.

[0055] Further, refer to Figure 1-2 As for the longitudinal movement of the lifting part 2, specifically, a lifting screw 10 is provided on the base 1. The lifting part 2 slides longitudinally with the base 1 and maintains threaded cooperation with the lifting screw 10. By rotating the lifting screw 10, the lifting process of the lifting part 2 can be controlled, and the height of the lifting part 2 can be accurately controlled to facilitate the end sealing process.

[0056] Further, refer to Figure 1 The present invention also includes a digital display module 11 and a rotation angle detection module. The rotation angle detection module is connected to the digital display module 11 and is used to detect the rotation angle of the lifting screw 10. This design can intuitively display the longitudinal movement information of the adsorption platform during the sealing process for easy observation by personnel. For the rotation angle detection module, a proximity switch can be used, which can be set on the base 1.

[0057] Further, refer to Figure 1-2 The lifting part 2 is also fixedly connected to a supporting foot 12. When the lifting part 2 moves down to the extreme position, the supporting foot 12 forms an overlap on the base 1, thereby ensuring the stability of the lifting part 2 and thus ensuring the stability of the vacuum adsorption platform 402.

[0058] Further, refer to Figure 1-4 The scraping mechanism of the present invention further includes the following parts:

[0059] A second support portion 13 is connected to the base 1 via a second slide rail mechanism 14, and the second slide rail mechanism 14 extends below the entire workpiece fixing mechanism;

[0060] The copper paste platform 15 is fixedly connected to the second support portion 13 and is used to place the paste material;

[0061] In the present invention, when performing the scraping operation, the paste material is placed on the copper paste platform 15, and the material is flattened by the leveling mechanism, so that the second support part 13 drives the copper paste platform 15 to move to the bottom of the workpiece fixing mechanism, and then the end sealing is completed by moving the vacuum adsorption platform 402. The second slide rail mechanism 14 extends to the bottom of the workpiece fixing mechanism, so that when the device as a whole is sealing, the workpiece fixing mechanism as a whole does not need to perform a large-scale horizontal movement, and the copper paste platform 15 can be directly moved to the bottom of the vacuum adsorption platform 402. The copper paste platform 15 is lighter than the workpiece fixing mechanism. Therefore, by setting it to be movable, it is more convenient and flexible when aligning, and the end sealing process is simpler.

[0062] Further, refer to Figure 1-2 The second supporting portion 13 is also fixedly connected to a third touch portion 16 , and its structure is the same as above. The third touch portion 16 makes it easier to operate the movement of the copper paste platform 15 .

[0063] Furthermore, the copper paste platform 15 and the second support portion 13 can be set to a detachable connection mode to facilitate the cleaning of the copper paste platform 15. Specifically, for the disassembly mode, a plurality of first quick-change knobs 17 are threadedly connected to the second support portion 13. The first quick-change knobs 17 cooperate with the second support portion 13 to clamp the copper paste platform 15 to complete the fixation of the copper paste platform 15. When the first quick-change knob 17 is screwed, the position of the copper paste platform 15 on the second support portion 13 can also be fine-tuned, thereby increasing the practical effect.

[0064] Further, refer to Figure 1-3 The present invention also includes an anti-drip portion 18, which is used to receive the paste material and maintain a relatively fixed arrangement with the second support portion 13. During the scraping process, when the leveling mechanism leaves the copper paste platform 15, the anti-drip portion 18 can receive the material dripping from the leveling mechanism to keep the entire device tidy. The anti-drip portion 18 can adopt a box body structure; as for the fixing method here, specifically, the anti-drip portion 18 can be fixedly connected to the second support portion 13 or the copper paste platform 15.

[0065] Further, refer to Figure 1-4 , the leveling mechanism described in the utility model includes:

[0066] A connecting portion 19 is connected to the base 1 in a longitudinal sliding manner, and there are at least two connecting portions 19;

[0067] The paste knife 20 and the scraper knife 21 are fixedly mounted on the two connecting parts 19 respectively;

[0068] Driving mechanisms 22 , the number of which corresponds to the connecting parts 19 , and the connecting parts 19 are kept in longitudinal motion by the driving mechanisms 22 ;

[0069] By operating the two driving mechanisms 22 separately, the longitudinal movement of the paste knife 20 and the scraper knife 21 can be independently controlled, so as to better complete the material flattening process and accurately control the laying thickness of the material, thereby improving the end sealing quality;

[0070] Reference Figure 2 From the perspective, the process of capacitor sealing of the present invention is that the paste knife 20 is first pressed down, and the copper paste platform 15 is moved to the rightmost side in the figure, so that the scraper knife 21 is pressed down, and the copper paste platform 15 is moved to the leftmost side. The vacuum adsorption platform 402 rotates and flips with the JIG plate carrying the capacitor, and then moves down. The sealing process is completed by the movement of the second touch part 7. Then, the adsorption platform is controlled by the lifting screw 10 to complete the final recovery, and the vacuum adsorption platform 402 is rotated and reset again to release the adsorption of the platform and then carry out unloading.

[0071] Further, refer to Figure 1-4 The driving mechanism 22 includes a downward pressing toggle clamp 22a and a connecting rod 22b. The downward pressing toggle clamp 22a is hingedly connected to the base 1, and the two ends of the connecting rod 22b are respectively hingedly connected to the connecting part 19 and the downward pressing toggle clamp 22a. By controlling the swing of the downward pressing toggle clamp 22a, the longitudinal movement of the paste knife 20 or the scraper knife 21 can be accurately controlled for easy operation.

[0072] Further, refer to Figure 2 The blade ends of the paste returning knife 20 and the paste scraping knife 21 are both inclined, and the two maintain symmetrical shapes, so that when returning the paste and scraping the paste, the inclined surface can form a shoveling and pressing effect on the material, thereby further ensuring the quality of material laying.

[0073] Furthermore, the paste knife 20 and the scraper 21 are both detachably connected to the connecting portion 19, so similarly, the paste knife 20 and the scraper 21 can be taken down for cleaning. Figure 1-4 As shown, the paste knife 20 and the scraper knife 21 can be connected to the connecting portion 19 via a second quick-change knob 23 .

[0074] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
