Abstract
Description
Technical Field
[0001] The utility model relates to an assembly tool for a pulse capacitor, in particular to a shell installation tool for a high-energy storage pulse capacitor. Background Art
[0002] With the development of modern science and technology, new demands have been put forward for electronic components, and the demand for energy storage density of capacitors is particularly urgent. Improving the energy storage density of capacitors and reducing the volume and weight of power supply systems have become urgent demands for miniaturization and lightweight of new concept high-energy power supply systems. High-energy storage pulse capacitors (generally metallized film capacitors) are an important component of the energy storage system of high-power pulse power supplies, and the volume of capacitors occupies the main part of the power supply system.
[0003] One of the bottlenecks in the development of high-energy pulse capacitors is insulation treatment, among which the shell installation process (i.e. the process of installing the capacitor core into the metal shell) is an important link that affects the insulation performance of the capacitor. Shell installation is an undetectable and untestable process, which is the process of assembling the capacitor core covered with an insulating protective layer into the metal shell.
[0004] In order to avoid damaging the insulating protective layer by clamping the capacitor core group, the traditional shell installation method of high-energy storage pulse capacitors generally adopts a manual shell installation method by multiple people. The shell is pre-placed flat on the ground with its open end at one horizontal end. Multiple people work together to push the core group into the shell, and then the product is placed upright to complete the shell installation.
[0005] The traditional shell installation method of high-energy pulse capacitors has the following defects: for high-energy pulse capacitors, the core group is very large and weighs tens of kilograms, while the movable space inside the shell is only a few centimeters. It is particularly difficult for the operator to manually install such a bulky core group into the narrow shell. It is necessary to adjust the position many times, the steps are cumbersome, the shell installation efficiency is low, and it is easy to cause abrasion and scratches on the insulating protective layer of the core group (especially the folded protective layer at the junction of the end faces), which ultimately leads to failure of the insulation test and requires reprocessing, which reduces the pass rate and increases the rework cost. Utility Model Content
[0006] The purpose of the utility model is to solve the above problems and provide a casing tool for a high-energy storage pulse capacitor which can better protect the insulating layer and is efficient.
[0007] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0008] The cam is secured to the bottom of the base and has a spring that allows the cam to move along the length of the base so that the cam can move along the length of the base, the spring having a cam portion that is secured to the bottom of the base and a spring that allows the cam to move along the length of the base.
[0009] Preferably, in order to improve the thrust and stability of the pushing cylinder, the pushing cylinder is a hydraulic cylinder and has two push rods.
[0010] Preferably, for ease of control, a control button for controlling the push cylinder is provided on the panel of the base.
[0011] The beneficial effects of the utility model are:
[0012] The utility model selectively installs a support plate on the base, connects the bottom baffle plate and the side baffle plates on the support plate, installs ball bearings on corresponding areas of the support plate and the side baffle plates, installs a pushing cylinder in the base and its push rod is rotatably connected to the support plate. When in use, the metal shell of the high-energy storage pulse capacitor is placed on the support plate and limited by the bottom baffle plate and the side baffle plates, the capacitor core group of the high-energy storage pulse capacitor is placed on the ball bearings of the support plate and contacts with the ball bearings of the side baffle plates, thus limiting the metal shell and the capacitor core group accordingly. Then, the support plate is rotated upward by the pushing cylinder, and with the assistance of manual labor, the capacitor core group can be easily pushed into the metal shell to achieve the purpose of shell installation, reduce the difficulty of shell installation, improve the shell installation efficiency, avoid or significantly reduce the damage to the insulating protective layer of the capacitor core group during the shell installation process, and improve the product quality stability and reliability.

[0015] The utility model is further described below in conjunction with the accompanying drawings:
[0016] like Figure 1 As shown, the shell installation tooling of the high energy storage pulse capacitor of the utility model comprises a base 1, a push cylinder 2 and a support plate 6, the first end of the two ends of the horizontal support plate 6 is connected to the lower end of the vertical bottom baffle 10 (it can be an integrally formed structure or an independently processed and interconnected structure), one side of the support plate 6 is connected to the lower side of the vertical side baffle 7 (it can be an integrally formed structure or an independently processed and interconnected structure), the bottom baffle 10 and the support plate 6, the side baffle 7 and the support plate 6, and the bottom baffle 10 and the side baffle 7 are respectively perpendicular to each other, the support plate 6 is installed above the base 1 and its first end is connected to the top plate of the base 1 (not marked in the figure) One end of the support plate 6 is rotatably connected to the support plate 6 by a hinge through a pin 9, and an area A between the second end and the middle part of the two ends (this area is just defined as area A for the convenience of citing its relationship later) and an area B on the side baffle 7 corresponding to the area A (this area is just defined as area B for the convenience of corresponding to the quoted area A) are respectively installed with a plurality of freely rotatable balls 5 (the installation method is determined according to specific needs and can be easily achieved by using existing technology), the base 1 is provided with an inner cavity and a base through hole 4 is provided on its top plate, the push cylinder 2 is installed in the inner cavity of the base 1 and the end of its push rod 3 passes through the base through hole 4 and is rotatably connected to the bottom of the support plate 6.
[0017] Preferably, in order to improve the thrust and stability of the push cylinder 2, the push cylinder 2 is a hydraulic cylinder and has two push rods 3. For easy control, a control button 8 for controlling the push cylinder 2 is provided on the panel of the base 1 (controlling the operation of a push cylinder such as a hydraulic cylinder or a pneumatic cylinder by a button is a prior art).
[0018] like Figure 2 As shown, when in use, firstly, the push rod 3 of the push cylinder 2 is retracted through the control button 8, so that the support plate 6 is in a horizontal position, and silicone oil is applied on the support plate 6 and the surface of the insulating protective layer of the capacitor core group 11 of the high energy storage pulse capacitor; then, the metal shell 12 of the high energy storage pulse capacitor is placed on the support plate 6 by other equipment such as a forklift or a micro crane, so that the open end of the metal shell 12 faces the direction close to the ball 5, and one side of the metal shell 12 is closely contacted with the side baffle 7 by manual assistance, at this time, the limit of the metal shell 12 is achieved. Then, the capacitor core group 11 is placed on the ball 5 on the support plate 6 (in order to avoid damaging the insulating layer, it is best to use manual handling), and one side of the capacitor core group 11 is in close contact with the ball 5 on the side baffle 7. At this time, the limited placement of the capacitor core group 11 is completed; the relative position between the placed capacitor core group 11 and the metal shell 12 is determined by the installation height of the ball 5, and the installation height of the ball 5 is determined by the actual gap between the capacitor core group 11 and the metal shell 12, which can be designed and assembled in advance.
[0019] Then, the push rod 3 of the push cylinder 2 is extended through the control button 8, and the extension length is determined according to the actual situation. The staff assists and slightly supports the capacitor core group 11, so that the capacitor core group 11 slowly slides into the metal shell 12; after the capacitor core group 11 is completely entered into the metal shell 12, the push rod 3 of the push cylinder 2 is extended to a greater length, so that the metal shell 12 is closer to the open end and faces upward, and then the metal shell 12 loaded with the capacitor core group 11 is moved to the ground through other equipment, and the excess silicone oil on the surface of the support plate 6 and the metal shell 12 is cleaned before entering the subsequent assembly process.
