Description

Technical Field

[0001] The present invention relates to the technical field of supercapacitor manufacturing, and in particular to a button-type supercapacitor negative electrode cover tray. Background Art

[0002] The production of button-type supercapacitors is characterized by a large number of capacitors and a small size. In the early stage of button-type supercapacitor production, the processes of electrode dispensing, punching, liquid injection, positive and negative electrode buckling were all performed manually, with low production efficiency; moreover, the transfer of electrode shells from one process to the next was also performed individually, with low material transfer efficiency. With the advancement of technology, the production process of supercapacitors has gradually adopted multiple manipulators to be carried out simultaneously. Compared with manual labor, the assembly speed of manipulators is fast and the precision is high. In addition, the production efficiency is further improved by using multiple manipulators at the same time. However, the equipment cost is very high when multiple manipulators are used at the same time, and a large production space is required. The production of supercapacitors requires an environment with high cleanliness and low humidity. The larger the production space, the greater the purchase cost of equipment such as dehumidifiers to create the production environment and the energy consumption cost of maintaining the operation of the equipment will be greatly increased. Therefore, production enterprises are in urgent need of a tray that can hold dozens to hundreds of negative electrode caps at one time, so that a large number of negative electrode caps can be operated at one time in the corresponding process, and the entire tray of negative electrode caps can be transferred at one time during the material transfer process. At the same time, these trays can be stacked vertically to reduce the occupancy of the operating table. Summary of the invention

[0003] The present invention provides a button-type supercapacitor negative electrode cover tray to meet the above requirements.

[0004] The technical solution of the present invention is: a button-type supercapacitor negative electrode cover tray, including a tray body and a positioning hole, characterized in that the tray body is provided with a cover support arranged closely, the cover support includes a shoulder support, a bottom support concentric with the shoulder support, and an assembly hole at the bottom concentric with the bottom support; the top of each of the two ends of the tray body in the length direction has a tray shoulder, and the bottom has a tray foot.

[0005] In this structure, the plate is made of plastic or metal and can withstand baking at temperatures above 100°C for a long time without deformation.

[0006] In this structure, the distance between the centers of two adjacent shoulder pads is 1-3 mm larger than the diameter of the shoulder pad.

[0007] In this structure, the diameters of the shoulder support and the bottom support are 0.05-0.15 mm larger than the diameters of the shoulder and bottom of the capacitor negative electrode cover, respectively, and the heights of the shoulder support and the bottom support are respectively equal to the heights of the shoulder and bottom of the capacitor negative electrode cover.

[0008] In this structure, the height of the plate shoulder is 0.5-1mm, and the height of the plate foot is 1-3mm.

[0009] The advantages of the present invention are that, depending on the size of the button-type supercapacitor, dozens to hundreds of negative electrode caps can be placed at one time, so that the processes of dispensing, punching, injecting and fastening can be completed at one time for the above-mentioned large number of negative electrode caps, which greatly improves the production efficiency compared with the traditional method of operating only one negative electrode cap at a time.

[0010] The present invention is designed with a tray shoulder and a tray foot, which are used in conjunction with each other to achieve the stacking of trays, thereby reducing the occupation of the production table by materials.

[0011] With the aid of the present invention, the negative electrode caps can be transferred as a single tray or as a plurality of trays stacked together at one time. Compared with transferring the negative electrode caps individually, the material transfer efficiency is greatly improved.

[0012] The design of the tray shoulder and tray foot of the present invention allows a gap to exist between adjacent trays when the trays are stacked, making it easier to take the trays during the production process.

[0013] The cover tray of the present invention is closely arranged, which reduces the generation of scraps in the electrode sheet punching process. The electrode sheet accounts for the main cost of supercapacitor production. The reduction of scraps means a reduction in production costs.

[0014] The cover support of the present invention is composed of a shoulder support, a bottom support and an assembly hole. This three-level structural design enables the shoulder and bottom of the negative electrode cover to fit tightly with the shoulder support and bottom support of the tray, ensuring that the negative electrode cover remains stable during the production process; and the design of the assembly hole ensures accurate positioning in subsequent processes.

[0022] Example 1

[0023] like Figures 1 to 6 As shown, a button-type supercapacitor negative electrode cover tray comprises a tray body (1) and a positioning hole (2). The tray body is provided with cover supports (3) arranged closely, and the cover supports (3) comprise a shoulder support (31), a bottom support (32) concentric with the shoulder support (31), and an assembly hole (33) at the bottom concentric with the bottom support (32). Both sides of the tray body (1) in the length direction are provided with tray shoulders (4) and tray feet (5).

[0024] The tray (1) is made of plastic or metal. Since the electrode drying process requires the tray and the negative electrode to be placed in a vacuum oven for baking, the tray is required to be able to withstand baking at a temperature above 100° C. for a long time without deformation.

[0025] In consideration of the structural characteristics of the human palm, the length and width of the tray should be designed to allow workers to repeatedly hold the tray firmly without causing hand fatigue.

[0026] In order to reduce the generation of scraps, the cover supports are arranged closely, and the distance between the centers of two adjacent shoulder supports (31) is 1-3 mm larger than the diameter of the shoulder supports (31).

[0027] In order to enable the negative electrode cover to smoothly enter and exit the cover support (3) and ensure subsequent accurate alignment, the diameters of the shoulder support (31) and the bottom support (32) are respectively 0.05-0.15 mm larger than the shoulder and bottom diameters of the capacitor negative electrode cover.

[0028] In order to make the negative electrode cover fit tightly with the cover support (3) without affecting the operation of subsequent processes, the heights of the shoulder support (31) and the bottom support (32) are respectively equal to the heights of the shoulder and bottom of the capacitor negative electrode cover.

[0029] The bottom of the cover support (3) is provided with an assembly hole (33) which is concentric with the bottom support (32). In the subsequent process, a fixture can pass through the assembly hole (33) to absorb the negative electrode cover for subsequent assembly.

[0030] The top of the tray body (1) has a tray shoulder (4) at each end in the length direction, and the bottom has a tray foot (5). The tray shoulders (4) and the tray feet (5) are used together to achieve stacking of trays. The height of the tray shoulder (4) is 0.5-1mm, and the height of the tray foot (5) is 1-3mm. When multiple trays are stacked, there is a gap between the bottom of the tray body (1) of the upper tray and the top of the tray body (1) of the lower tray of two adjacent trays, which facilitates the relative movement between the trays and also facilitates the stacking and taking of the trays.

[0031] The disc body (1) is provided with four symmetrically distributed positioning holes for aligning the pole pieces in processes such as punching, dispensing, and injecting liquid.

[0032] In actual use, a plurality of negative electrode caps are placed in one piece on each cap support (3) of the tray of the present invention through a specific device, and subsequent processes such as dispensing glue, punching, pressing, and injecting liquid can be completed in one piece on the tray. The negative electrode caps can be transferred in one piece, or the trays can be stacked and then transferred in one piece.
