Description

Technical Field

[0001] The utility model relates to the technical field of square batteries, in particular to a semi-automatic film coating machine for square batteries. Background Art

[0002] Prismatic batteries are a common type of battery with a rectangular or square shape. These batteries are commonly used in a variety of electronic devices, such as remote controls, laptops, watches, and even some medical devices. They are often called "lithium-ion prismatic batteries" or "button batteries" because most of them are made of lithium ions and have a flat circular positive electrode and a larger negative electrode as well as an insulated and sealed metal casing. Prismatic cells usually need to be packaged with insulating film to prevent short circuits and protect the cell surface from the external environment. The insulating film can effectively reduce the direct contact between the cell and the external environment, ensuring the safety and stability of the cell.

[0003] The existing square battery cell packaging insulation film is manually operated, which is not only inefficient, but also sometimes fails to tighten the insulation film, resulting in wrinkles on the square surface of the insulation film. Utility Model Content

[0004] The utility model aims to provide a semi-automatic film wrapping machine for square batteries, which has the advantages of adjusting the height of the insulating film when wrapping the square battery so that the insulating film can be tightly attached to the surface of the square battery, thereby improving the film wrapping speed and solving the problem of low efficiency and easy wrinkling of manual film wrapping of square batteries.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a semi-automatic coating machine for square batteries, comprising a fixed plate, a spring and a roller, support plates are respectively welded on both sides of the top of the fixed plate, two support plates are respectively embedded with a bearing 1, two inner rings of the bearings 1 are respectively fixedly installed with a fixing rod 1, and two opposite ends of the fixing rods 1 are respectively installed with a cylinder 1, a fixing frame is welded at the front end of the fixed plate, springs are symmetrically installed at the top of the fixing frame, and retaining frames are installed at the bottom of the two springs, two bearings 2 are respectively embedded with both sides of the retaining frame, two inner rings of the bearings 2 are respectively fixedly installed with a fixing rod 2, and two opposite ends of the fixing rods 2 are respectively installed with a cylinder 2, a connecting frame is symmetrically installed on the top of the fixed frame, and rollers are respectively rotatably installed on the inner sides of the two connecting frames.

[0006] When using the semi-automatic film coating machine for square batteries in the technical solution, the fixing seat provides support for the fixing plate, the square battery is placed between the two clamping plates, the two cylinders push the two clamping plates to clamp and fix the square battery, the insulating film is rolled between the two clamping rollers, the two cylinders push the two clamping rollers to move and clamp and fix the insulating film, and one end of the insulating film is fixed on the surface of the square battery after it is untied, and the hand wheel is used to rotate the fixing rod one, and the fixing rod one drives the square battery to rotate through the cylinder one and the clamping plate. When the square battery rotates, the insulating film is wrapped to the surface, and the square battery will exert a tensile force on the insulating film during the wrapping process. The spring at the top of the retaining frame will be extended when subjected to the tensile force, and will shrink after the tensile force disappears. The retaining frame rises and falls with the extension and contraction of the spring, and when the retaining frame rises and falls, the movable rod moves in the movable hole, and the roller rotates with the rise and fall of the movable rod. The friction between the roller and the movable rod reduces the lifting speed of the movable rod.

[0007] Preferably, clamping plates are respectively installed at opposite ends of the two cylinders, and the two clamping plates are parallel to each other. The two cylinders push the two clamping plates to clamp and fix the square battery.

[0008] Preferably, a hand wheel is installed at one end of the fixing rod 1 on one side of the top of the fixing plate. The fixing rod 1 can be rotated using the hand wheel.

[0009] Preferably, clamping rollers are respectively installed at opposite ends of the two cylinders 2, and the two clamping rollers are parallel to each other. The two cylinders 2 push the two clamping rollers to move and clamp and fix the insulating film.

[0010] Preferably, a movable hole is opened on the fixed frame on the opposite side of the two rollers, and a movable rod is installed on the top of the retaining frame, and the top of the movable rod passes through the movable hole, and the movable rod contacts the two rollers. The movable rod limits the retaining frame, and when the retaining frame is raised or lowered, the movable rod moves in the movable hole, and the roller rotates with the lifting and lowering of the movable rod. The friction between the roller and the movable rod reduces the lifting speed of the movable rod, thereby preventing the retaining frame from shaking.

[0011] Preferably, fixing seats are respectively installed at the four corners of the bottom of the fixing plate, and the fixing seats are perpendicular to the bottom of the fixing plate. The fixing seats provide support force for the fixing plate.

[0012] Preferably, the retaining frame is perpendicular to the fixing plate, and the retaining frame will not be skewed when it is raised or lowered.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model fixes the insulating film inside the retaining frame by arranging a spring and a retaining frame. After the insulating film is untied, one end is fixed on the surface of the square battery. A hand wheel is used to rotate a fixing rod. The fixing rod drives the square battery to rotate through a cylinder and a clamp. When the square battery rotates, the insulating film is wrapped to the surface. The square battery applies a tensile force to the insulating film during the wrapping process. The spring at the top of the retaining frame is extended when subjected to the tensile force, and then contracts after the tensile force disappears. The retaining frame rises and falls as the spring is extended and contracted. When the retaining frame is lifted and lowered, the movable rod moves in the movable hole, and the roller rotates as the movable rod is lifted and lowered. The friction force generated by the roller and the movable rod reduces the lifting speed of the movable rod, so that the height of the insulating film is adjusted when the square battery is wrapped, so that the insulating film can be tightly attached to the surface of the square battery, thereby improving the wrapping speed.
