Description

Material receiving and flattening device for winding core of film capacitor

Technical Field

The utility model relates to a film capacitor processingequipment, more specifically say, relate to a film capacitor coils the core and connects material and flatten the device.

Background

The metallized film capacitor has high insulation resistance, small capacitance loss, reliability, safety and explosion resistance, and is widely used in the fields of electronics, communication, electric power and the like.

The metallized film is the main material for making metallized film capacitor, the base material of said material is organic film, such as polyester and polypropylene, etc., and the metal is plated on the medium base material by means of vacuum coating. The capacitor is formed by winding two or more metallized films and a plain film, and the metal plating layers of the metallized films are very thin and are very easy to oxidize. If wrinkles are generated during the manufacturing process and air or moisture is contained in the wrinkles, the metal plating layer therein is easily ionized or oxidized, thereby degrading the characteristics of the capacitor and reducing the attenuation or failure of the capacitor capacity. Especially for the capacitor applied to the DC supporting occasions such as new energy automobiles, electrified locomotives, solar power generation and the like, if the capacitor fails, huge loss is brought.

When the capacitor is manufactured, material receiving and capacitor core flattening after winding are also important links, and poor flattening process or mechanical action can cause internal damage and internal wrinkle increase of the capacitor, so that the quality of the capacitor is influenced. The capacitor core after winding is supported, positioned and transferred by the translation and up-and-down movement of the V-shaped plate in the processes of material receiving and flattening, and the positions of the V-shaped plate rising when receiving materials are different due to different outer diameters of capacitors with different specifications. If the material receiving V-shaped plate rises too little, the V-shaped plate and the capacitor are too far away, and when the capacitor core falls on the V-shaped plate, the capacitor is easily damaged or deformed or the capacitor directly contacts the V-shaped plate at the end face when falling; if the above bad condition takes place during the material receiving, probably will crush the core when the follow-up flattens the process, also can produce more inside folds to cause the defective products. If connect the material V template to rise too much, the V template can directly be pressed the condenser surface and make the electric capacity receive external force to damage the electric capacity. In the flattening process, the V-shaped plate rises to flatten the circular core, and the V-shaped plate is opened into a flat plate in the rising process, if the V-shaped plate is opened too early, the capacitor core is easy to roll and fall off or change the angle; if the V-shaped plate is opened too late, the capacitor core is additionally stressed by the V-shaped plate in the flattening process and is easily extruded and deformed or generates more internal wrinkles.

Based on the risk and the inconvenient part that there are above traditional mode of flattening, need urgently to need connect material and flatten the device to improve current film capacitor winding core to guarantee the quality of flattening of film capacitor winding core.

The synchronous belt mechanism is adopted to control the lifting mechanism 2 to move horizontally, and the moving position precision is high.

Because the servo motor 2-2 has a position mode and a moment mode, different control modes can be adopted according to the working conditions of material receiving and flattening. Specifically, in the embodiment, as shown in fig. 3, the V-shaped positioning mechanism 3 has a material receiving stop position and a translation conveying position at the material receiving station under the driving of the position mode of the servo motor 2-2, the height of the V-shaped positioning mechanism 3 at the translation conveying position is lower than that at the material receiving stop position, and the minimum distance between the V-shaped positioning mechanism 3 at the material receiving stop position and the surface of the capacitor core 5 on the discharging core is 2-3 mm; the V-shaped positioning mechanism 3 is driven by a torque mode of the servo motor 2-2 to have a flattening approaching position and a flattening stopping position at the flattening station, and the flattening approaching position is used for controlling the V-shaped positioning mechanism 3 to be opened into a plane state when the top of the capacitor core 5 is about to contact with the fixed pressing plate mechanism 4. The specific working process is explained as follows:

when the capacitor core 5 is connected, the V-shaped positioning mechanism 3 is moved to the position below the material receiving station through the horizontal driving mechanism 1-2, because the initial position of the bearing plate 3-4 in the V-shaped positioning mechanism 3, the outer diameter size of the capacitor core 5 and the initial relative distance between the bearing plate 3-4 and the material discharging and core pulling of the discharging mechanism are known, the ideal material receiving position of the bearing plate 3-4 can be calculated according to the known data, the minimum distance between the bearing plate 3-4 and the surface of the capacitor core 5 is 2-3 mm which is an ideal material receiving position, the ideal material receiving position of the V-shaped positioning mechanism 3 can be ensured, the position control is convenient and the precision is high, the capacitor core 5 is effectively prevented from being damaged due to the fact that the V-shaped positioning mechanism 3 is contacted with the capacitor core 5 when the capacitor core 5 rises, and the capacitor core 5 is prevented from falling damage and angle inclination due to the too far material receiving distance, the stability and reliability of the material receiving process are ensured. The calculation method can be seen in fig. 4 and 5, knowing an angle alpha between the support plate 3-4 and the vertical direction and the radius r of the capacitor core 5 when the initial relative distance H, V from the support plate 3-4 to the discharging core pulling of the discharging mechanism is known, when the capacitor core 5 is placed on the V-shaped support plate 3-4, the distance l from the center of the capacitor core 5 to the bottom of the V-shaped support plate 3-4 can be calculated by the formula sin α r/l, at the ideal material receiving position, the minimum distance delta r between the supporting plate 3-4 and the surface of the capacitor core 5 is 2-3 mm, therefore, when the material receiving position is ideal, the distance L between the discharging core and the bottommost part of the V-shaped bearing plate 3-4 is (r + delta r)/sin alpha, and the servo motor 2-2 drives the bearing plate 3-4 to rise to the height of the ideal material receiving position from the initial position, namely the difference H-L. The technical method can be built in a control system of the film capacitance winding device, and the delta r can be set by a touch screen of the control system. After the servo motor 2-2 drives the V-shaped positioning mechanism 3 to reach an ideal positioning position, the discharging core of the discharging mechanism is pulled out, the capacitor core 5 is placed on the V-shaped supporting plate 3-4, then the servo motor 2-2 drives the V-shaped positioning mechanism 3 to descend to a translation conveying position, and the capacitor core is conveyed to the next process by the horizontal driving mechanism 1-2. The next process can be used for reaming or checking the capacitor core 5, or can be used for directly flattening.

Before flattening, the V-shaped positioning mechanism 3 and the capacitor core 5 are driven by the horizontal driving mechanism 1-2 to move to a flattening station, namely, the V-shaped positioning mechanism 3 and the capacitor core 5 are positioned right below the fixed pressing plate mechanism 4, and then the servo motor 2-2 drives the V-shaped positioning mechanism 3 to ascend in a torque mode to prepare for flattening the capacitor core 5. As shown in fig. 6, it is necessary to spread the two support plates 3-4 of the V-shaped positioning mechanism 3 to a horizontal position when the condenser core 5 is flattened, and also, since the position of the upper press plate 4-3 of the fixed press plate mechanism 4, the outer diameter of the condenser core 5 and the initial position of the support plate 3-4 are known, the height of the capacitor core 5 which needs to be raised when the capacitor core contacts the upper pressure plate 4-3 can be obtained through simple calculation, the rising height is controlled by a servo motor 2-2, when the servo motor 2-2 drives a bearing plate 3-4 to reach the flattening approach position, the control system controls the air cylinders 3-10 of the V-shaped positioning mechanism 3 to act, the two bearing plates 3-4 are opened to be in a horizontal state, and the servo motor 2-2 further drives the V-shaped positioning mechanism 3 to ascend to flatten the capacitor core 5. After the flattening is finished, the supporting plate 3-4 is kept in a plane opening state, the servo motor 2-2 is switched to a position mode to move downwards and is driven by the horizontal driving mechanism 1-2 to a subsequent process, the subsequent process can be testing, transferring or screening, and the like, and the description is omitted.
