Description

Technical Field

[0001] This utility model relates to the field of sodium battery processing technology, specifically to a sodium battery electrode welding mechanism. Background Technology

[0002] Sodium batteries are batteries that use sodium ions as charge carriers. They have the ability to charge and store electricity and can replace lithium batteries as power supply mechanisms in certain fields. During charging, sodium ions pass through the electrolyte via the positive electrode material and then enter the negative electrode material. Electrons then reach the negative electrode through the external circuit, thus realizing the charging operation. Discharging is the reverse process.

[0003] The electrodes of this device are mostly made of layered transition metal oxide (NaxTMO2), and then fixed to the surface of the battery by a welding mechanism. Most of these welding mechanisms have a station to fix the sodium battery, and then weld the electrodes from the left and right sides. However, the battery sizes vary, and it is often difficult to adjust the position of the feeding mechanism. Manually holding the metal sheet is also very dangerous. There is an urgent need for an automatically adjustable feeding mechanism.

[0004] Now, a novel sodium battery electrode welding mechanism is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sodium battery electrode welding mechanism to solve the problem of inconvenient metal sheet feeding mentioned in the background art.

[0007] As a further technical solution of this utility model, the output end of the motor is fixedly connected to the worm gear, and the worm gear is meshed with the top of the worm wheel.

[0008] As a further technical solution of this utility model, the left side of the worm gear is fixedly connected to the lead screw, and the ferrule is symmetrically sleeved on the front and rear ends of the outer side of the metal sheet.

[0009] As a further technical solution of this utility model, a retaining sleeve is provided on both sides of the cavity. A groove is longitudinally provided in the center of the retaining sleeve, and a rotating wheel is movably connected to the lower sides of the groove. A cavity is provided at the bottom of the retaining sleeve. A gear disk one is longitudinally movably connected to the left side of the cavity, and a gear disk two is longitudinally movably connected to the right side of the cavity. A motor two is installed on the lower right side of the cavity. Support plates are fixed on both sides of the top of the base, and a cylinder is fixed on the outer side of the support plate. An electric heater is fixed on the side of the piston rod of the cylinder, and a welding head is installed on the side of the electric heater.

[0010] As a further technical solution of this utility model, the top of the output end of the second motor is fixedly connected to the second gear disk, and the first gear disk and the second gear disk are horizontally meshed.

[0011] As a further technical solution of this utility model, the tops of the first gear disk and the second gear disk are respectively fixedly connected to the rotating wheel, and the rotation directions of the first gear disk and the second gear disk are opposite.

[0012] As a further technical solution of this utility model, a movable groove is provided between the front and rear ends inside the bottom of the fixed base, and a screw is movably connected between the front and rear ends inside the movable groove. The front and rear ends of the screw are respectively threadedly connected to threaded sleeves, and a pressure block is fixed on the top of the threaded sleeve. A sponge block is fixed on the surface of the pressure block, and a motor is fixed at the center below the front end of the fixed base.

[0013] As a further technical solution of this utility model, the output end of the motor is fixedly connected to the screw, and the pressure block and the threaded sleeve are on the same vertical plane.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this sodium battery electrode welding mechanism not only realizes the adjustment of the feeding position and facilitates the pushing of electrode sheet raw materials, but also prevents the battery body from shaking. (1) By fixing the sleeves at the front and rear ends of the top of the sleeve block respectively, the battery body is placed horizontally in the fixed seat for clamping. The motor at the right rear is started to rotate the worm gear, which meshes and pushes the worm wheel at the bottom. The screw is rotated horizontally in the horizontal groove to guide the sleeve block and the sleeves at the front and rear ends to move in opposite directions, so that the metal sheet is attached to both sides of the battery body. The piston rod of the cylinder guides the welding head to approach the battery body. When the electric heater generates heat, the metal sheet is hot-pressed and welded to both sides of the battery body to become electrodes. (2) By setting a cavity at the bottom of the card sleeve, the metal sheet is inserted longitudinally into the front and rear symmetrical card sleeves. The motor two at the bottom of each card sleeve is started and the gear disk two is rotated. The gear disk two meshes with and pushes the gear disk one on the side, guiding the rotating wheels on both sides of the groove to rotate in the opposite direction, pushing the metal sheet from back to front, so that it can be welded to the left and right sides of the battery body. No manual operation is required, and automatic feeding is achieved. (3) By fixing a sponge block on the surface of the pressure block, the battery body is placed horizontally in the slot of the fixing seat, and the motor is started to rotate the screw together, so that the front and rear symmetrical threaded sleeves slide along the moving groove. The pressure block above the threaded sleeve is attached to the front and rear ends of the battery body through the sponge block, which prevents the battery body from loosening and can also improve the accuracy of welding electrodes. Here, the sponge block can automatically change according to the shape of the battery body, making the clamping very firm. Attached Figure Description
