Description

Technical Field

[0001] The utility model relates to a battery feeding short-circuit prevention mechanism, belonging to the technical field of lithium battery production. Background Art

[0002] The operating principle of cylindrical lithium batteries is similar to that of conventional lithium-ion batteries, generating electricity through a chemical reaction. During charging, lithium ions in the positive electrode material dissolve and migrate to the surface of the negative electrode material, forming a thin electrolyte film. During discharge, the lithium electrolyte film is carried away by the current, and lithium ions dissolve from the negative electrode material and return to the positive electrode material, releasing electricity.

[0003] The structure of a cylindrical lithium battery primarily consists of a positive electrode, negative electrode, electrolyte, separator, and outer casing. The positive electrode material can be lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), lithium nickel cobalt manganese oxide (LiNiMnCoO2 or NMC), lithium nickel cobalt aluminum oxide (LiNiCoAlO2 or NCA), lithium iron phosphate (LiFePO4), and lithium titanate (Li4Ti5O12). The negative electrode material is typically carbon. The electrolyte is an organic solvent containing a lithium salt. The separator is located between the positive and negative electrodes to prevent internal short circuits. The outer casing is typically made of steel or aluminum to protect the battery's internal components, including the cell and electrolyte.

[0004] The inventors have discovered that the prior art has at least the following technical problems:

[0005] During the production process of cylindrical lithium batteries, lithium batteries need to be removed from the battery box and placed on a battery conveyor belt. Since the lithium battery shells are usually made of steel or aluminum shells during the production process, when electromagnets are used to directly suck them out, collisions between batteries can easily cause short circuits, causing damage to the batteries. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a battery loading and short-circuit prevention mechanism to avoid the short-circuit phenomenon caused by the battery being taken out.

[0007] The battery feeding and short-circuit prevention mechanism of the utility model comprises a battery receiving assembly and a battery removing assembly respectively mounted on both sides of the battery conveyor belt;

[0008] The battery removal assembly includes a support frame I installed on one side of the battery conveyor belt, a telescopic cylinder is installed on the support frame, an electromagnet is installed on the telescopic rod of the telescopic cylinder, and an insulating shell is installed on the outside of the electromagnet;

[0009] The battery accommodating assembly includes a support frame II installed on one side of the battery conveyor belt. The support frame II is correspondingly installed with two side plates for accommodating the battery box body, and a baffle is installed at one end of the side plate for blocking the battery in the battery box body.

[0010] Furthermore, the baffle is made of a transparent plate.

[0011] Furthermore, the telescopic cylinder adopts a cylinder arrangement, guide plates are installed on both sides of the cylinder, and guide rods with sliding fit are installed on the electromagnet corresponding to the guide plates.

[0012] Furthermore, a positioning plate is provided on the support frame II corresponding to the baffle.

[0013] Furthermore, the battery removal assembly also includes a protective shell installed outside the support frame I.

[0014] Furthermore, the distance between the lowermost end of the baffle and the battery conveyor belt is greater than . times the diameter of the battery.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model effectively avoids short circuit caused by collision during the removal of the battery through the design of the insulating shell outside the electromagnet and the baffle of the battery receiving assembly.

[0017] The utility model can automatically take the battery out of the battery box body and place it on the battery conveyor belt, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] like Figures 1 to 3 As shown, the battery loading and short-circuit prevention mechanism of the present invention comprises a battery receiving assembly 1 and a battery removing assembly 3 correspondingly mounted on both sides of a battery conveyor belt 2;

[0029] The battery removal assembly 3 includes a support frame I 34 mounted on one side of the battery conveyor belt 2, a telescopic cylinder 33 is mounted on the support frame, an electromagnet 32 ​​is mounted on the telescopic rod of the telescopic cylinder 33, and an insulating shell 31 is mounted on the outside of the electromagnet 32;

[0030] When the telescopic cylinder 33 is extended, the insulating shell 31 outside the electromagnet 32 ​​abuts against one end of the battery 4 opposite. At this time, current passes through the electromagnet 32, and the electromagnet 32 ​​attracts the battery. As the telescopic rod of the telescopic cylinder 33 is reset, the electromagnet 32 ​​cuts off the current, and the battery 4 is placed on the battery conveyor belt 2.

[0031] The battery accommodating assembly 1 includes a support frame II 13 installed on one side of the battery conveyor belt 2, and two side plates 12 for accommodating the battery box body 5 are correspondingly installed on the support frame II 13. A baffle 11 for blocking the battery 4 in the battery box body 5 is installed at one end of the side plate 12.

[0032] The baffle 11 is made of a transparent plate. The transparent plate can be made of organic glass (acrylic plate) or other materials, such as polycarbonate (PC) plate, PVC, PS plate, etc. This allows inspectors to clearly observe the arrangement of the batteries 4 within the battery case 5, preventing the batteries 4 from being misplaced and becoming stuck during removal.

[0033] The telescopic cylinder 33 is arranged in an air cylinder configuration, with guide plates 331 correspondingly mounted on both sides of the air cylinder, and guide rods 321 slidably mounted on the electromagnet 32 ​​corresponding to the guide plates 331 .

[0034] The guide rods 321 are symmetrically arranged on both sides of the cylinder, and the movement of the cylinder is made more stable through the sliding cooperation between the guide rods 321 and the guide plates 331 .

[0035] A positioning plate 131 is further provided on the support frame II corresponding to the baffle 11 .

[0036] The battery removal assembly 3 further includes a protective shell 35 installed outside the support frame I 34.

[0037] The distance between the lower end of the baffle 11 and the battery conveyor belt 2 is greater than 1.2 times the diameter of the battery 4, so that the battery 4 can be easily removed from the battery receiving assembly 1.

[0038] The battery conveyor belt 2 is provided with a number of raised bars, through which the batteries 4 are separated and positioned.

[0039] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up and down, does not constitute a limitation of the present invention and is only for the convenience of description.
