Description

Technical Field

[0001] The utility model belongs to the field of aging equipment for electronic devices, and particularly relates to an oven and an oven tray for aging capacitors and lithium batteries. Background Art

[0002] Capacitors and lithium batteries have electrode foils inside. During the production process, they go through multiple complex manufacturing processes, which can cause varying degrees of damage to the oxide films on the surface of the electrode foils, especially the positive electrode foil. Therefore, capacitors need to be aged, that is, by applying a rated aging voltage and aging for a certain period of time in a constant high-temperature environment, in order to repair the damaged oxide films of the electrode foils. For large-diameter capacitors and lithium batteries, due to their large volume and high capacity, etc., currently, manual aging is still mostly used. Workers need to insert capacitors and lithium batteries onto a special loading rack, put the special loading rack into the oven, power on the special loading rack, set electrical parameters, and set the aging time. All these processes need to be completed manually, resulting in low production efficiency and a large number of defective products caused by human factors. These situations all bring unnecessary losses to the manufacturers of capacitors and lithium batteries.

[0003] Current aging equipment includes dynamic aging equipment and static aging equipment. In the dynamic aging equipment, a feeding mechanism inserts capacitors and lithium batteries onto a rack equipped with special fixtures. Through chain transmission, a manipulator grabs the entire rack onto the transmission chain of a tunnel furnace. Conductive devices are provided at both ends of the rack and are connected to each fixture. The rack makes intermittent movements in the tunnel furnace. Since contact brush power supply is used, continuous power supply cannot be achieved. In the static aging equipment, workers rely on manual operation to insert capacitors and lithium batteries onto special fixtures. However, manual operation not only has low work efficiency but also easily causes problems such as insecure clamping of aging materials and reverse insertion of electrodes. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an oven and an oven tray for aging capacitors and lithium batteries, which can fully integrate the advantages of high automation and high production efficiency of dynamic aging and continuous power supply and full-process monitoring of static aging.

[0005] The utility model is realized as follows. An oven tray for aging capacitors and lithium batteries includes a tray main body. Aging monitoring modules, wireless communication modules, and multiple special loading racks are arranged on the tray main body. Materials are clamped on the special loading racks. Conductive wires are arranged at each station on the special loading racks for clamping materials and are electrically connected to the aging monitoring modules. During the aging process of the materials, the aging monitoring modules will monitor the aging process of the materials and transmit the monitoring data to the upper computer in real time through the wireless communication modules for the upper computer to judge the quality of the materials and give timely feedback.

[0006] Based on the same inventive concept, the utility model further provides a capacitor and an oven for a lithium battery aging device. The oven includes a chain conveying mechanism, a continuous power supply component, and a plurality of the above-mentioned oven trays. The oven is divided into a loading / unloading station, an aging station, and a pre-unloading detection station; the chain conveying mechanism is used to drive a plurality of the oven trays to reciprocate between the loading / unloading station, the aging station, and the pre-unloading detection station, so that the oven trays are recycled in the oven;

[0007] The continuous power supply component is used to continuously supply power to all oven trays.

[0008] Further, the oven has an upper and a lower space. The chain conveying mechanism includes a lower conveying chain, a side lifting chain, an upper conveying chain, and a side lowering chain. Among them, the lower conveying chain is located in the lower space, the upper conveying chain is located in the upper space, and the side lifting chain and the side lowering chain are respectively located on the left and right sides of the oven; the oven trays are driven by the combined traction of the lower conveying chain, the side lifting chain, the upper conveying chain, and the side lowering chain to perform a cyclic reciprocating motion inside the oven;

[0009] One or more groups of feeding special rack lifting mechanisms are arranged at fixed positions in the lower space of the oven. When the oven tray moves to the position of the feeding special rack lifting mechanism, the feeding special rack lifting mechanism will lift the corresponding feeding special rack to facilitate loading and unloading operations;

[0010] After each feeding special rack is loaded at the loading / unloading station, the lower conveying chain moves the oven tray to the next feeding special rack for loading. When an oven tray completes the loading action, the side lifting chain lifts one oven tray upward, the side lowering chain moves one oven tray downward, and the upper conveying chain moves one oven tray to the right, and this cycle repeats in sequence.

[0011] Further, the continuous power supply component includes an L - pole conductive bar fixed on the oven, an N - pole conductive bar fixed on the oven, and two groups of brush electrodes installed on the oven tray; the L - pole conductive bar and the N - pole conductive bar are insulated from the oven and are distributed in a rectangular shape.

The oven also arranges a short section of N - pole conductive bar and L - pole conductive bar at the turning position where the oven tray moves to assist the oven tray to achieve continuous power supply at the turning point; the two groups of brush electrodes installed on the oven tray are diagonally distributed up and down, and each group of brush electrodes has three elastic contact heads arranged in a triangular shape. One group of brush electrodes includes one N - pole contact head and two L - pole contact heads, and the other group of brush electrodes includes one L - pole contact head and two N - pole contact heads; during the entire reciprocating motion process, at least one of the L - pole contact heads and N - pole contact heads on each oven tray is in corresponding contact with the L - pole conductive bar and N - pole conductive bar fixed on the oven to ensure continuous power supply.

[0012] Further, multiple temperature zones with different temperatures are provided at the aging station of the oven to meet the precise temperature control requirements for each aging stage; the oven trays are divided into a high-temperature end and a normal-temperature end according to the regions where they are located. The materials are clamped on the special loading rack at the high-temperature end, and the aging monitoring module and the wireless communication module are arranged at the normal-temperature end.

[0013] Further, an oven loading and unloading switch clamping mechanism is also provided in the oven. The oven loading and unloading switch clamping mechanism includes a left positioning cylinder, an opening clamp bearing, an opening clamp cylinder, an auxiliary positioning cylinder assembly, a right positioning cylinder, and a right positioning top block; when the special loading rack lifting mechanism lifts the special loading rack to the loading and unloading height, the right positioning cylinder pushes the right positioning top block installed on the linear guide rail to move forward. Four groups of the auxiliary positioning cylinder assemblies arranged front and rear act, and then the left positioning cylinder acts to precisely position the special loading rack; the opening clamp cylinders arranged side by side drive the opening clamp bearing installed on the linear guide rail to reciprocate to complete the opening and clamping actions; each group of cylinders can be individually controlled, and cooperate with the loading manipulator to reciprocate the material loading actions in sequence. After the loading is completed, the positioning cylinders at the front, rear, left, and right positions retract in sequence, and the special loading rack lifting mechanism retracts, and the special loading rack returns to the oven tray inside the oven.
