Description

[Technical field]

[0001] The invention relates to automated production, automated assembly and packaging technology for capacitors, and in particular to a positioning discharge and shockproof integrated blister tray for aluminum electrolytic capacitors. [Background technology]

[0002] Capacitors are one of the electronic components used in large quantities in electronic equipment. They are widely used in circuits such as DC isolation, AC pass, coupling, bypass, filtering, tuning circuits, energy conversion and control. For example, Gree Electric Appliances, a major domestic air-conditioning manufacturer, has an annual demand of 120 million horn-type high-power capacitors.

[0003] During the storage process, capacitors will generate voltage. If the residual electricity in the capacitors is not discharged, the electronic components may be burned. Therefore, the packaging of capacitors generally puts a piece of aluminum foil under the pins of the capacitors to achieve the effect of discharge. Manufacturers of capacitors generally use carton packaging, and the capacitors are separated by knife cards in the carton. The disadvantages of this method are: first, the production and packaging of capacitors and the assembly, extraction, welding and positioning are all done manually, which has low production efficiency; second, the knife card and the capacitor are a loose structure, which cannot fix the direction of the capacitor and has limited protection; third, the aluminum foil is placed under the knife card. If such a thin material is slightly deformed, it is difficult to ensure that dozens of capacitors on it can contact the aluminum foil at the same time, and it is impossible to ensure that all are discharged.

[0004] Moreover, with the promotion of production automation technology, various manufacturers are exploring the use of blister trays to assemble capacitors, but all of them adopt single-layer blister trays with aluminum foil under the tray. The disadvantages of this method are: first, the single-layer structure requires the tray to be made of very thick materials, resulting in high costs. The single-layer structure cannot bear the weight of the tray, making it difficult to grab and move the tray as a whole; second, the aluminum foil is separated from the tray, making it difficult to recycle all packaging materials, increasing production costs; third, the production and assembly of capacitors both increase the process of grabbing aluminum foil and cardboard, affecting the efficiency of automated production.

[0005] It is precisely because of the above reasons that it is difficult for capacitor manufacturers to achieve automated processes. Most of them still use cartons and paper knife cards, a very inefficient manual assembly method. [Summary of the invention]

[0006] The present invention provides an aluminum electrolytic capacitor positioning, discharging and shockproof integrated blister tray which has a simple structure and integrates capacitor positioning and shockproof packaging. The tray adopts a double-layer structure, greatly reduces the material thickness while still greatly increasing the tray's tensile and bending strengths. The tray can be extracted as a whole without deformation, effectively reducing the cost of packaging materials. The conductive aluminum foil is connected to the tray as a whole, which is convenient for overall recycling and turnover use, and is beneficial to environmental protection and cost reduction.

[0007] The technical solution adopted by the present invention to solve its technical problem is:

[0008] An integrated blister tray for positioning, discharging and shockproofing of aluminum electrolytic capacitors is used for batch storage and transportation of multiple capacitors, including an upper tray integrally stamped from a plastic material, on which a plurality of array-arranged receiving slots for inserting and placing each capacitor are formed by a depression downward from the upper surface;

[0009] The bottom surface of each receiving groove is provided with a first pin hole and a second pin hole respectively matched with two pin sheets on the bottom surface of the capacitor;

[0010] The two pin sheets on the capacitor are mutually offset and deflected at a certain angle, and the first pin hole is offset relative to the second pin hole to form a double-hole structure positioning hole for the capacitor to be inserted into the receiving groove at a unique angle with the two pin sheets as positioning base surfaces;

[0011] The bottom of the upper tray is also connected with a lower chassis for supporting the pin sheets of the capacitor extending from the first pin hole and the second pin hole respectively. The lower chassis is recessed downward and is integrally provided with supporting grooves that partially fit with each accommodating groove of the upper tray. After the lower chassis is connected with the upper tray by a buckle, a double-layer stacked plate frame structure is formed to increase the tensile and bending strength of the upper tray.

[0012] Furthermore, among the multiple array-arranged receiving grooves, four circumferentially adjacent receiving grooves are respectively provided in the middle of each other with reinforcing rib grooves which are recessed downward from the upper surface of the upper tray and are used to increase the strength of the tray body.

[0013] Furthermore, the bottom surface of each supporting groove on the lower chassis shrinks inward to form a stepped bottom cavity groove, and the bottom of each bottom cavity groove is respectively provided with a conductive foil that contacts the two pin sheets of the capacitor and is used for self-discharging after the two pin sheets of the capacitor are electrically connected.

[0014] Furthermore, the multiple supporting grooves on the lower chassis are arranged in an array corresponding to the accommodating grooves on the upper tray, and reinforcing rib grooves are provided in the middle of four circumferentially adjacent supporting grooves, which are recessed downward from the upper surface of the lower chassis and are used to increase the strength of the tray body.

[0015] Furthermore, at least one group of arc-shaped convex rib grooves protruding inwards and used for circumferential positioning and fitting of the wall surfaces of the two are respectively provided on the buckle contact surfaces of the supporting groove of the lower chassis and the receiving groove of the upper tray.

[0016] Furthermore, the accommodating groove is a circular groove for inserting a cylindrical capacitor.

[0017] Furthermore, the bottom of the upper tray is also connected with a lower chassis for receiving the pin pieces of the capacitor extending from the first pin hole and the second pin hole respectively. The lower chassis is recessed downwardly and is provided with supporting grooves that are partially fitted with each accommodating groove of the upper tray. The bottom surface of each supporting groove shrinks inward to form a stepped bottom cavity groove. The bottom of each bottom cavity groove is respectively provided with a penetration hole for the two pin pieces of the capacitor to pass through. The bottom surfaces of all the bottom cavity grooves of the corresponding lower chassis are attached with a conductive foil that is in contact with the pin pieces of all the capacitors and is used for self-discharge after electrical connection between the two pin pieces of each capacitor. After the lower chassis is connected with the upper tray by a buckle, a double-layer stacked plate frame structure is formed to increase the tensile and bending strength of the upper tray.

[0018] Furthermore, the multiple supporting grooves on the lower chassis are arranged in an array shape corresponding to the accommodating grooves on the upper tray, and in the middle of the four circumferentially adjacent supporting grooves, there are also reinforcing rib grooves that are recessed downward from the upper surface of the lower chassis and are arranged flush with the bottom cavity groove, which are used to increase the strength of the tray body and support and position a conductive foil.

[0019] Furthermore, among the plurality of receiving grooves arranged in an array, four receiving grooves adjacent to each other in the circumferential direction are respectively provided in the middle of each of them, and a reinforcing cylindrical column is provided which is recessed downward from the upper surface of the upper tray and has a bottom surface higher than the bottom surface of the receiving groove, and is used to increase the strength of the tray body;

[0020] The height difference between the bottom surface of the reinforcing cylindrical column and the bottom surface of the receiving groove forms a receiving cavity for receiving the two pins of the capacitor extending outward, and the bottom surfaces of all the reinforcing cylindrical columns on the bottom side of the upper tray are also glued or welded with a flat film for replacing the lower chassis and contacting the first pin and the second pin extending outward from the capacitor on the bottom side of the upper tray respectively; the flat film is glued or welded to the upper tray to form a double-layer stacked plate frame structure for increasing the tensile and bending strength of the upper tray;

[0021] The flat film is provided with aluminum foil strips corresponding to each row of receiving slots on the upper tray, and the aluminum foil strips are in contact with two pin sheets of all capacitors in each row of receiving slots and are used for self-discharging after all capacitors are electrically connected.

[0022] Furthermore, the front and rear sides of the upper tray are recessed inwardly to provide a first positioning side groove and a second positioning semicircular groove for positioning the tray body when the capacitor is to be loaded or unloaded, and a plurality of second positioning semicircular grooves are respectively staggeredly arranged on the inner sides of the first positioning side grooves on the front and rear sides of the upper tray; the corresponding left and right sides of the upper tray are also recessed inwardly to provide a third positioning side groove distributed obliquely to the opposite sides and used for positioning the tray body when the capacitor is to be loaded or unloaded.

[0023] The beneficial effects of the present invention are:

[0024] The present invention integrates intelligent positioning, discharge, shockproof and packaging of capacitors, and is used for batch storage, transportation, discharge and convenient grabbing of automated equipment for multiple capacitors. The bottom buckle of the upper tray is connected with the lower chassis. After the lower chassis is connected with the upper tray buckle, a double-layer stacked plate frame structure is formed to increase the tensile and bending strength of the upper tray; this structure is compared with a single structure, while reducing the material by 20%, and the bending strength of the tray is doubled. A circular aluminum foil is attached to the circular hole of the lower tray. After the pins of the capacitor pass through the holes of the upper tray, they contact the aluminum foil, which can release the residual electricity of the capacitor and avoid the accumulated charge of the capacitor. The overall structure of this positioning, discharge and shockproof integrated blister packaging tray is simple, not easy to deform, convenient for automatic storage and automatic taking, and the tray as a whole can be recycled and reused, which can reduce the production and assembly links of capacitors, reduce the process of automated production, and improve production efficiency.

[0025] In the present invention, the bottom surface of each receiving groove on the upper tray is provided with a first pin hole and a second pin hole respectively matched with the two pin pieces on the bottom surface of the capacitor; the two pin pieces on the capacitor are mutually offset and deflected at a certain angle, and the first pin hole is offset relative to the second pin hole to form a double-hole structure positioning hole in which the capacitor uses the two pin pieces as the positioning base surface and is positioned and inserted into the receiving groove at a unique angle; in this way, the overall double-layer structure is adopted, and the single-layer structure is simple and easy to process, and is not easy to deform. While greatly reducing the material thickness, the tensile and bending strength of the tray is still greatly increased, and the tray can be extracted as a whole without deformation, which effectively reduces the cost of packaging materials. It is convenient to automatically store and automatically take out the capacitor, which can reduce costs and improve work efficiency. Moreover, the aluminum foil is bonded to the tray, so that the tray as a whole can be recycled, the product is environmentally friendly and effectively reduces production costs.

[0026] Moreover, the bottom buckle of the upper tray is connected to the lower chassis or the stepped tray groove. After the lower chassis or the stepped tray groove are respectively connected to the buckle of the upper tray, a double-layer stacked plate frame structure is formed to increase the tensile and bending strength of the upper tray, effectively increasing the tensile and bending strength of the upper tray, and facilitating the storage and transportation of capacitors.

[0027] At the same time, a conductive foil, a conductive foil strip, or a conductive foil paper is respectively arranged on the lower chassis or plastic plate corresponding to the lower side of the upper tray, which is in contact with the pin sheet on each capacitor. It is used for self-discharging of the capacitor after the electrical connection is made, preventing the capacitor from generating corona during storage, and improving the reliability of the product.

[0028] In addition, the front and rear sides of the upper tray are recessed inwardly to provide a first positioning edge groove and a second positioning semicircular groove for positioning the tray body when the capacitor is to be loaded or unloaded. Correspondingly, the left and right sides of the upper tray are also recessed inwardly to provide a third positioning edge groove distributed obliquely to the opposite sides and used for positioning the tray body when the capacitor is to be loaded or unloaded. In this way, the capacitor can be automatically positioned during the loading and unloading process, thereby realizing automated loading and unloading operations.
