DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0028] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] As disclosed in the background technology, there are three main packaging ideas for improving the vibration resistance of the core package in the prior art: one is to fix the internal core package by waisting at an appropriate position in the length direction of the aluminum shell surface; the second is to fix the core package by injecting glue into the inner bottom of the aluminum shell; the third is to reduce the gap between the core package and the aluminum shell by putting a rubber ring on the core package to improve the vibration resistance of the core package. Among them, the method of fixing the core package by injecting glue into the inner bottom of the aluminum shell has become the mainstream choice of capacitor manufacturers because it is easier to implement. However, the capacitor industry currently does not have a mature automated packaging equipment with the function of injecting glue into the inner bottom of the capacitor aluminum shell. Basically, it is mainly based on manual injection of glue into the inner bottom of the capacitor aluminum shell.

[0031] At the same time, one of the effective methods of existing technology to improve the sealing effect of products is to apply sealant to the surface of the product sealing part to seal the gap between the sealing part and the lead terminal and the gap between the sealing part and the aluminum shell; however, the capacitor industry currently does not have mature automated packaging equipment with the function of injecting glue to the surface of the capacitor sealing part, and basically relies on manual injection of glue to the surface of the capacitor sealing part.

[0032] The method of manually injecting glue inside and on the surface of the aluminum shell has the following disadvantages:

[0033] 1. During manual operation, multiple links need to be operated in series. For example, in the process of injecting glue into the aluminum shell, it is necessary to inject glue into the aluminum shell first, then put the core package into the aluminum shell, and then put the semi-finished product into the oven for drying to preliminarily solidify the glue inside the aluminum shell, and finally seal it manually. The workload of workers is large, the time is long and the efficiency is low, which is not suitable for mass production.

[0034] 2. The manual operation speed is limited, which may cause the core package to absorb moisture in the air due to long-term exposure to the air, affecting product performance and reliability; at the same time, manual operation may cause product contamination, affecting product performance and reliability.

[0035] 3. There is a lot of discreteness in manual work, which leads to large differences in the weight and uniformity of glue distribution inside and outside different products, which has a great impact on the fixing effect of the internal core package and the sealing effect of the sealing part surface.

[0036] 4. The glue material itself and the waste gas and waste liquid it produces during the operation may be harmful to the human body.

[0037] 5. The high temperature during the glue drying process can easily cause burns.

[0038] In order to solve the above problems, the present invention provides an automated packaging device, and some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0039] First embodiment

[0040] Please refer to Figures 1 to 3 (The dotted line in the figure indicates the direction of product movement). This embodiment provides an automated packaging device 100 that can realize an automated glue injection process, realize internal glue injection and surface glue injection, ensure the product's vibration resistance and sealing performance, and avoid a series of problems caused by manual operation. At the same time, it can ensure that the glue distribution is uniform and has little difference, thereby ensuring the consistency of the product.

[0041] The automated packaging equipment 100 provided in this embodiment includes a core package conveying production line 110, a feeding vibration plate 120, an aluminum shell glue injection device 130, a combination device 140, a sealing waist device 150 and a surface glue injection device 160. The core package conveying production line 110 extends to the downstream of the aluminum shell glue injection device 130 to provide core packages. The feeding vibration plate 120 is used to realize the feeding of the aluminum shell 210. The aluminum shell glue injection device 130 is arranged downstream of the feeding vibration plate 120 to inject glue into the aluminum shell 210. 0 internal glue injection, the combined device 140 is arranged downstream of the aluminum shell glue injection device 130 and downstream of the core package conveying production line 110, and is used to put the core package into the aluminum shell 210 and form a semi-finished product 200, the sealing and waisting device 150 is located downstream of the combined device 140, and is used to perform curling sealing and waisting on the semi-finished product 200, and the surface glue injection device 160 is arranged downstream of the sealing and waisting device 150, and is used to perform surface glue injection on the semi-finished product 200 after curling sealing and waisting.

[0042] In this embodiment, the automated packaging equipment 100 is suitable for capacitor products, wherein the capacitor products include an aluminum shell 210 and a core package encapsulated inside the aluminum shell 210. The aluminum shell 210 uses a glue injection process to ensure the anti-vibration performance of the capacitor product, and the packaging surface also uses a glue injection process to ensure the sealing of the capacitor product. In this embodiment, the feeding vibration plate 120 is used to realize the vibration feeding of the aluminum shell 210, and then the aluminum shell glue injection device 130 is used to complete the glue injection action inside the aluminum shell 210, and the core package is placed in the aluminum shell 210 using the combination device 140 to complete the assembly of the semi-finished product 200. Finally, the sealing and waisting actions are completed using the sealing waist device 150, and then the surface glue injection device 160 is used to complete the surface glue injection to ensure its sealing. The whole process does not require manual participation, avoiding manual operation, and the process is simple and efficient. At the same time, the glue injection effect is good, avoiding the core package from being exposed to the air for a long time, and ensuring the reliability and performance of the product. And the consistency is good, ensuring the product quality, and also avoiding the problem of harmful environment and health caused by manual operation.

[0043] It should be noted that the upstream and downstream in this embodiment refer to the upstream or downstream in the movement direction of the aluminum shell 210, the core package or the semi-finished product 200, wherein the aluminum shell 210, the core package and the semi-finished product 200 are different components of the capacitor product. The aluminum shell 210 passes through the loading vibration plate 120, the aluminum shell injection device 130 and the assembly device 140 in sequence, the core package is provided by the core package conveying production line 110, and the semi-finished product 200 assembled by the assembly device 140 passes through the sealing waist device 150 and the surface injection device 160 in sequence, moving from upstream to downstream.

[0044] In this embodiment, a first drying tunnel 170 is further provided between the assembly device 140 and the sealing waist-binding device 150. The first drying tunnel 170 is provided downstream of the assembly device 140, and the sealing waist-binding device is provided downstream of the first drying tunnel 170. The first drying tunnel 170 is used to dry the semi-finished product 200 so that the glue inside the semi-finished product 200 is at least partially cured. Specifically, the first drying tunnel 170 is used to dry the glue inside the aluminum shell 210 so that it can be pre-cured, ensure a certain molding structure, and facilitate the subsequent sealing waist-binding action.

[0045] In this embodiment, a second drying tunnel 180 is further provided downstream of the surface glue injection device 160. The second drying tunnel 180 is used to dry the semi-finished product 200 after the surface glue injection, so that the glue on the surface of the semi-finished product 200 is at least partially cured. Specifically, the second drying tunnel 180 is used to dry the glue on the surface of the aluminum shell 210 so that it can be pre-cured to prevent the surface glue from flowing and affecting the sealing performance during subsequent actions.

[0046] In this embodiment, a pan-swing device 190 is further provided downstream of the second drying tunnel 180. The pan-swing device 190 is provided with a plurality of receiving holes for assembling the semi-finished product 200. The pan-swing device 190 is used to swing and fix the semi-finished product 200. Specifically, the plurality of receiving holes in the pan-swing device 190 can fix a plurality of semi-finished products 200. Each semi-finished product 200 is placed in the receiving hole with the body facing downward and the lead wire facing upward, so as to ensure that the glue that is initially cured inside the aluminum shell 210 of the semi-finished product 200 and at the sealing portion does not flow.

[0047] In this embodiment, after the staggering device 190 performs staggering, the plurality of semi-finished products 200 may be put into the drying oven again and baked for a period of time to ensure that the glue inside the aluminum shell 210 and on the surface of the sealing portion is completely cured.

[0048] In this embodiment, the surface glue injection device 160 includes a glue injection interface and a turntable. The turntable is used to carry the semi-finished product 200 and drive the semi-finished product 200 to rotate. The glue injection interface is set on one side of the turntable, and is used to inject glue to the semi-finished product 200 in a rotating state. Specifically, when injecting glue on the surface, the semi-finished product 200 is injected while rotating 360 degrees, thereby ensuring the uniformity of the surface injection. In addition, the sealing waist device 150 uses the sealing member 230 to complete the sealing operation of the aluminum shell 210. At the same time, this embodiment can optimize the aluminum shell curling shape of the sealing member 230, and leave a gap between the end of the aluminum shell 210 and the sealing member 230, so that the glue can flow to the gap between the sealing member 230 and the aluminum shell 210, thereby ensuring that all areas of the surface of the sealing member 230 are evenly injected with glue.

[0049] It should be noted that, in order to increase the heat dissipation capacity of the product, the glue inside the aluminum shell 210 in this embodiment preferably uses glue with a certain thermal conductivity, such as glue doped with thermal conductive materials. Of course, the glue on the surface of the aluminum shell 210 can also use glue with thermal conductivity.

[0050] In this embodiment, a horizontal conveying track 121 is further provided between the feeding vibration plate 120 and the aluminum shell glue injection device 130. The horizontal conveying track 121 is located downstream of the feeding vibration plate 120, and the aluminum shell glue injection device 130 is located on the side of the horizontal conveying track 121 away from the feeding vibration plate 120. The horizontal conveying track 121 is used to carry multiple aluminum shells 210 sent out by the feeding vibration plate 120 and arrange the multiple aluminum shells 210 together. Specifically, the horizontal conveying track 121 is used to neatly arrange the multiple aluminum shells 210, which is convenient for the aluminum shell glue injection device 130 to complete the glue injection, and also convenient for the assembly device 140 to continuously remove the multiple aluminum shells 210 and assemble them with the multiple core packs, further improving the assembly efficiency.

[0051] In this embodiment, a detection device 131 is further provided downstream of the aluminum shell glue injection device 130, and the detection device 131 is used to detect the glue injection status of the plurality of aluminum shells 210, and discharge the aluminum shells 210 with poor glue injection from the horizontal conveying track 121. The glue injection here can be completed by using a pneumatic glue injection system or a quantitative pump, and the detection of the presence of glue can be achieved by using a sensor detection or the like.

[0052] In this embodiment, a glue detection mechanism 161 is also provided between the surface glue injection device 160 and the second drying tunnel 180, which is used to detect the semi-finished parts 200 after glue injection, and timely check the semi-finished parts 200 with poor glue injection, so as to ensure that the surfaces of all semi-finished parts 200 are evenly glued, and the defective parts are automatically discharged before entering the second drying tunnel 180, and the glue on the surface can be manually wiped off and then manually put into the glue injection place for glue injection again. Preferably, the glue detection mechanism 161 can be directly provided on the surface glue injection device 160, and its detection principle is the same as that of the detection device 131, which will not be described in detail here.

[0053] The core package conveying production line 110 includes a core package oven 111, a robot assembly 113 and an insulation box 115. The core package oven 111 contains a plurality of racks, each of which is arranged with a plurality of iron bars, each of which is used to fix and support a plurality of core packages. The insulation box 115 is arranged downstream of the core package oven 111. The robot assembly 113 is arranged between the core package oven 111 and the insulation box 115, and is used to take the rack out of the core package oven 111. The robot assembly 113 is also used to take at least one of the iron bars off the rack and put it into the insulation box 115. The combination device 140 is arranged downstream of the insulation box 115. Specifically, a plurality of racks are stacked in the core package oven 111, and an opening is provided on one side of the core package oven 111. The robot assembly 113 can take out one of the racks through the opening, and the rack taken out by the robot assembly 113 is gradually moved outward from the top of the core package oven 111, and is only moved outward by the distance between two iron bars each time, so as to facilitate the unloading of a single iron bar.

[0054] In this embodiment, the core package conveying production line 110 further includes an empty rack unloading device 117, which is disposed between the core package oven 111 and the heat preservation box 115 and is located below the manipulator assembly 113, and is used to carry empty racks. Specifically, after the multiple iron bars on the racks are unloaded one after another, the empty racks are sent to the empty rack unloading device 117 by the manipulator assembly 113 for stacking. After all racks in the batch have completed unloading, the alarm device can be used to warn the operator to remove all empty racks in the batch and prepare for the next batch of operations.

[0055] The manipulator assembly 113 includes a first manipulator and a second manipulator that are adjacently arranged. The first manipulator is used to take the rack out of the core package oven 111, and the second manipulator is used to take at least one iron bar on the rack and put it into the heat preservation box 115. The first manipulator is also used to put the empty rack into the empty rack unloading device 117. Of course, the manipulator assembly 113 here can also use multiple manipulators to jointly complete the actions of taking out the rack and unloading the iron bars.

[0056] A cutting mechanism is provided at the outlet of the heat preservation box 115 for cutting off the multiple core packages on the iron bar one by one, so as to facilitate the subsequent combination with the aluminum shell 210 under the action of the combination device 140.

[0057] The working principle of the automated packaging equipment 100 provided in this embodiment is as follows:

[0058] Multiple racks from the same batch are put into the core package oven 111, and multiple iron bars welded with core packages are arranged on each rack. The robot assembly 113 for lifting the racks automatically lifts the rack arranged at the top, and the racks lifted by the robot assembly 113 are gradually moved outward from the top of the side of the core package oven 111, and are only moved outward by the distance of two iron bars each time.

[0059] When one of the iron bars is removed from the oven, the robot assembly 113 transfers the iron bar to the heat preservation box 115 for standby use. When all the iron bars on the rack are removed, the empty rack will automatically unload to the empty rack unloading device 117 downstream, and automatically complete the stacking of all the empty racks in the batch. After all racks in the batch have completed unloading, the equipment alarms that the batch is over, and the empty racks are manually removed to prepare for the next batch.

[0060] A plurality of aluminum shells 210 are automatically loaded from the loading vibration plate 120 to the horizontal conveying track 121 and arranged neatly, and the internal glue injection action is completed by the aluminum shell glue injection device 130, and the detection is completed by the detection device 131, and the aluminum shells 210 with poor glue injection will be automatically discharged.

[0061] The single iron bar is cut off at the outlet of the heat preservation box 115 , and the multiple core packages are cut off from the iron bar and combined with the aluminum shell 210 under the action of the combining device 140 .

[0062] The semi-finished product 200 formed by combining the aluminum shell 210 and the core package by the combining device 140 is dried while moving in the first drying tunnel 170 , and the initial curing of the glue inside the aluminum shell 210 is completed at the exit of the first drying tunnel 170 .

[0063] The semi-finished product 200 after the initial solidification of the glue inside the aluminum shell 210 completes the waisting and curling sealing at the sealing waisting device 150, and the semi-finished product 200 after the waisting and curling sealing completes the surface glue injection operation of the sealing part 230 at the surface glue injection device 160. In order to ensure that the surface of the sealing part 230 can be evenly coated with glue, the surface glue injection device 160 adopts the method of rotating the semi-finished product 200 while injecting glue, and at the same time optimizes the curling shape, leaving a gap between the end of the aluminum shell 210 and the sealing part 230, so that the glue can flow to the gap between the sealing part 230 and the aluminum shell 210, thereby ensuring that all areas of the surface of the sealing part 230 are evenly injected with glue.

[0064] The semi-finished product 200 with the glue injected on the sealing surface is placed in the second drying tunnel 180 for preliminary drying, and it is ensured that the glue on the surface of the sealing part 230 at the exit of the second drying tunnel 180 has been initially solidified.

[0065] After the glue on the surface of the sealing part 230 is initially cured, the semi-finished part 200 will be automatically placed on a plate by the swinging device 190. The multiple accommodating holes in the swinging device 190 can fix multiple semi-finished parts 200. Each semi-finished part 200 is placed in the accommodating hole with the body facing downward and the lead facing upward to ensure that the glue that has initially cured inside the aluminum shell 210 of the semi-finished part 200 and at the sealing part will not flow.

[0066] Finally, the entire tray of semi-finished products 200 will be placed in a drying oven and baked for a period of time to ensure that the glue inside the aluminum shell 210 and on the surface of the sealing member 230 is completely cured.

[0067] In this embodiment, the performance test is conducted on the product that has passed the automated packaging equipment 100, and the following table is obtained, which can further prove that the glue injection method of the core package inside and outside the present application has a good glue injection effect and ensures the reliability and performance of the product. Among them, Table 1 is a conventional product, that is, a product without glue injection, and Table 2 is a product provided in this embodiment, that is, a product with glue fixed at the bottom of the aluminum shell and sealant on the surface of the sealing member.
