Description

Technical Field

[0001] The utility model relates to capacitor production equipment, in particular to an old chemical equipment for capacitor production. Background Art

[0002] After the production process is completed, capacitors need to be aged. Aging is a process that treats capacitors for a period of time under specific conditions (such as temperature, voltage, etc.) to simulate their long-term performance in actual use. The purpose of this is to evaluate and ensure the performance, reliability and life of the capacitor in actual use.

[0003] Specifically, aging treatment helps to identify and eliminate capacitors that may show performance degradation at an early stage. Through aging treatment, potential defects inside the capacitor can be detected, such as impurities in the dielectric, oxidation or corrosion of the electrodes, etc., which may cause the performance degradation or failure of the capacitor in actual use. In addition, aging treatment can also promote certain physical and chemical processes inside the capacitor, such as uniform distribution of electrolyte and stabilization of the plates, thereby improving the stability and performance of the capacitor. Through aging treatment, the capacitor can better adapt to the environmental conditions in actual use, such as temperature changes, voltage fluctuations, etc.

[0004] Capacitor aging requires corresponding aging equipment, and each aging equipment can perform aging tests on dozens or even hundreds of capacitors at the same time. However, the current aging equipment is not suitable for automated loading and unloading, and requires a lot of manpower costs. Therefore, how to efficiently install a large number of capacitors on aging equipment has become an urgent problem to be solved in the capacitor production industry. Different capacitors have pins of different sizes, so improving the versatility of aging equipment is also an urgent problem to be solved. Summary of the invention

[0005] The utility model provides an aging equipment for capacitor production, which solves the problem that capacitor aging equipment in the prior art is not suitable for automatic loading and unloading and has poor versatility.

[0006] The above technical problems of the utility model are mainly solved by the following technical solutions: an aging tool for capacitor production, characterized in that it includes a fixed seat, an adjustment seat and a plurality of tooling units distributed in an array, the length direction of the adjustment seat is parallel to the length direction of the fixed seat, a first sliding block is slidably mounted on the fixed seat along its length direction, and a second sliding block is slidably mounted on the adjustment seat along its length direction; the tooling units are generally in an equidistant linear array, and the array direction is consistent with the length direction of the fixed seat, the tooling units include a positive pin clamping module and a negative pin clamping module, the positive pin clamping module includes a positive pin guide fixed on the fixed seat, a positive fixed seat fixed relative to the fixed seat, A positive electrode spring piece fixed on the positive electrode fixing seat and a positive electrode clamping block fixed on the first sliding block, the negative electrode pin clamping module includes a negative electrode pin guide fixed on the fixing seat, a negative electrode fixing seat fixed relative to the adjusting seat, a negative electrode spring piece fixed on the negative electrode fixing seat and a negative electrode clamping block fixed on the second sliding block; the aging equipment also includes a driving assembly that can synchronously drive the two sliding blocks to reciprocate; a positive electrode circuit board is also provided on the fixing seat, the positive electrode spring piece is electrically connected to the printed circuit on the positive electrode circuit board, a negative electrode circuit board is also provided on the adjusting seat, the negative electrode spring piece is electrically connected to the printed circuit on the negative electrode circuit board, and the positive circuit board and the negative circuit board are respectively connected to the positive and negative circuits.

[0007] The positive pin clamping module and the negative pin clamping module of the utility model are respectively equipped with a positive pin guide and a negative pin guide. The structure of the pin guide is a funnel-shaped structure, and the opening at the lower end thereof is directly opposite to the area between the spring sheet and the clamping block. Therefore, when the two pins of the capacitor are inserted simultaneously against the two pin guides, the pins can be reliably and efficiently inserted into the area between the spring sheet and the clamping block on the lower side under the guidance of the pin guides. Then the driving component pushes the first sliding block and the second sliding block to move synchronously, so that the clamping block moves toward the side of the clamping spring sheet until the pin is firmly clamped. At this time, the aging equipment completes the fixation of the capacitor and the aging treatment can be carried out; conversely, the driving component pulls the two sliding blocks, so that the clamping block moves away from the spring sheet. At this time, the pin is released and the capacitor can be removed from the utility model. Since the utility model has a low requirement for the position accuracy of the pin, even if the pin has a certain degree of deformation or displacement, it can be inserted into place under the guidance of the pin guide. For this reason, the utility model can be matched with a manipulator to complete autonomous loading and unloading.

[0008] At the same time, the distance between the fixing seat and the adjusting seat in the utility model can be adjusted, thereby changing the distance between the positive pin clamping module and the negative pin clamping module to adapt to capacitors of different sizes, so that the utility model has better versatility.

[0009] Furthermore, the positive circuit board is provided with a PTC element connected in series with the positive spring piece. A PTC element refers to a thermistor with a positive temperature coefficient. The resistance value of this element increases with the increase of temperature and has a positive temperature coefficient characteristic. The resistance-temperature characteristic of the PTC element is that as the temperature increases, its resistance value has a minimum value (the corresponding temperature point is the Curie point) and a maximum value. Within the positive temperature coefficient range, the current flowing through the element increases, the electric power increases, and the temperature of the element increases, which increases the resistance value, thereby causing the current to decrease and the electric power to decrease. When the temperature rise caused by the electric power is balanced with the heat dissipation, the temperature and resistance value no longer change. Therefore, the PTC element in the utility model mainly plays the role of protecting capacitors and aging circuits.

[0010] Therefore, compared with the prior art, the utility model has the following characteristics: 1. Since the utility model has lower requirements on the position accuracy of the pin, even if the pin has a certain degree of deformation or offset, it can be inserted into place under the guidance of the pin guide. For this reason, the utility model can be used with a robot to complete autonomous loading and unloading; 2. At the same time, the distance between the fixed seat and the adjustment seat in the utility model can be adjusted, thereby changing the distance between the positive pin clamping module and the negative pin clamping module to adapt to capacitors of different sizes, so that the utility model has better versatility.
