Description

Technical Field

[0001] This utility model relates to the field of new energy battery processing technology, and in particular to a cold heading device for new energy battery terminals. Background Technology

[0002] A new energy battery is a device that can store and release electrical energy. It is mainly used in new energy vehicles, energy storage systems, portable electronic devices and other fields. It can store a large amount of electrical energy. The battery cell terminals are an important part of the battery. They are responsible for guiding the electrical energy inside the battery out for use by external devices.

[0003] In the production of battery terminals, a cold heading process is required to achieve the desired shape. For example, Chinese Patent Publication No. CN118477963A discloses a stamping equipment for processing battery cell terminals, including a stamping table and a mounting frame fixedly installed on its top. A hydraulic cylinder is fixedly inserted into the top of the mounting frame, and a cold heading fixture for stamping the battery cell terminals is fixedly installed at the extended end of the hydraulic cylinder. A protective mechanism to prevent worker injury is provided on one side of the cold heading fixture. The mounting frame also has a coating mechanism for cleaning and lubricating several stamping grooves of the cold heading fixture. Oil is sprayed from the output ends of several spray pipes to wash the inner walls of the several stamping grooves of the cold heading fixture, flushing out debris. Simultaneously, the sprayed polishing oil fills the overflow storage tank, ensuring that the openings of the several stamping grooves of the cold heading fixture are all immersed in polishing oil, thus achieving the effect of evenly coating them with polishing oil, reducing the probability of damage to the cold heading fixture, and ensuring its service life.

[0004] In practice, lubricant needs to be sprayed around the electrode during processing to prevent damage. However, there is a lack of measures for collecting or recycling the lubricant after it is sprayed, and the processing time increases the cost of electrode processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot collect or recycle lubricant, and to propose a cold heading device for new energy battery terminals.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cold heading device for new energy battery terminals is designed, including a frame. A forming unit and a liquid supply unit are provided on the top of the frame. A collection box is provided on the side of the frame. The collection box is equipped with a feeding assembly and a filtration structure. The feeding assembly is used to feed the terminals and separate the coolant. The filtration structure is used to filter impurities inside the separated coolant.

[0008] Furthermore, the feeding assembly includes a guide plate, a plurality of rollers are rotatably connected to the bottom notch portion of the guide plate, a pair of guide posts are fixedly connected to both sides of the guide plate, and a pair of guide grooves are provided on the top two side walls of the collection box, with the guide posts and guide grooves being slidably connected.

[0009] Furthermore, it also includes a motor, which is fixedly connected to the bottom of the frame. The motor shaft has an eccentrically rotating connecting arm via a connector, and the other end of the connecting arm is rotatably connected to the guide plate.

[0010] Furthermore, the filter structure includes at least one pair of filter elements, each filter element having a cylindrical structure and an annular portion fixedly connected to its top opening. The volume of the plurality of filter elements decreases progressively, so that the plurality of filter elements are arranged in an inner and outer manner.

[0011] The bottom of the collection box is provided with a stepped hole for connecting the infusion tube, and the outermost annular part is engaged in the stepped hole.

[0012] Furthermore, the top of the annular portion is recessed inward on the side near the axis to form a first positioning structure, and its bottom is recessed inward on the side away from the axis to form a second positioning structure. The annular portions on the inner and outer sides are joined together by the first positioning structure and the second positioning structure.

[0013] Furthermore, protrusions and locking holes are respectively provided on the top of the first positioning structure and the second positioning structure, and the locking holes on adjacent sides are inserted into the protrusions and fixed by friction.

[0014] The present invention provides a cold heading device for new energy battery terminals, which has the following advantages: The present invention has a feeding assembly at the top of the collection box. The guide plate is driven to move back and forth by a motor and a connecting arm. On the one hand, the movement of the guide plate prevents the terminals from accumulating and affecting the feeding. On the other hand, the shaking during the feeding process causes the lubricating fluid adhering to the surface of the terminals to enter the collection box, reducing the difficulty of subsequent cleaning. In addition, multiple filter elements are also provided in the collection box. The multiple filter elements are stacked together, which can improve the reliability of filtering impurities in the lubricating fluid. On the other hand, cleaning the filter elements will not affect the normal use of the equipment. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A cold heading device for new energy battery terminals includes a frame 1, a forming unit 2 and a liquid supply unit 3 on the top of the frame 1, and a collection box 4 on the side of the frame 1. The collection box 4 contains a feeding assembly 5 and a filter structure 6. The feeding assembly 5 is used to feed the terminals and separate the coolant, and the filter structure 6 is used to filter impurities inside the separated coolant.

[0024] In some embodiments, the liquid supply unit 3 includes a liquid delivery pipe, which is connected to the liquid supply equipment and the nozzle. The nozzle is located on the side below the output end of the forming unit 2 and is used to spray lubricating liquid onto the electrode raw material to prevent damage caused by excessive friction during the cold forging process of the electrode.

[0025] The frame 1 is located below the forming unit 2 and is equipped with a conveying mechanism. The formed electrode is conveyed to the guide plate 51 through the conveying mechanism. The guide plate 51 moves back and forth to unload the electrode and to help clean the lubricant adhering to the outside of the electrode.

[0026] Furthermore, the feeding assembly 5 includes a guide plate 51, with several rollers rotatably connected to the bottom notch portion of the guide plate 51, and a pair of guide posts 52 fixedly connected to both sides of the guide plate 51. The collection box 4 has a pair of guide grooves 41 on its top two side walls, and the guide posts 52 are slidably connected to the guide grooves 41.

[0027] It is worth mentioning that several rollers are arranged at an angle to facilitate the feeding of the pole piece, and there is a drain groove between adjacent rollers. The lubricant enters the collection box 4 through the drain groove. Of course, the distance between the drain grooves on adjacent sides is smaller than the diameter of the pole piece.

[0028] Furthermore, it also includes a motor 53, which is fixedly connected to the bottom of the frame 1. The shaft end of the motor 53 has an eccentrically rotating connecting arm 55 through a connecting piece 54, and the other end of the connecting arm 55 is rotatably connected to the guide plate 51.

[0029] In specific operation, the motor 53 drives the connector 54 to rotate the connecting arm 55. Due to the eccentric rotation between the connector 54 and the connecting arm 55, the connecting arm 55 can drive the guide plate 51 to move back and forth.

[0030] Specifically, the guide post 52 is slidably connected in the guide groove 41 to improve the stability between the collection box 4 and the guide plate 51, and also to limit the sliding of the guide plate 51.

[0031] More specifically, the filter structure 6 includes at least one pair of filter elements 61, each filter element 61 having a cylindrical structure and an annular portion 62 fixedly connected to its top opening. The volume of the plurality of filter elements 61 decreases progressively, so that the plurality of filter elements 61 are arranged in an inner and outer manner.

[0032] The bottom of the collection box 4 is provided with a stepped hole 42 for communicating with the infusion tube, and the outermost annular part 62 is engaged in the stepped hole 42.

[0033] In general, the top of the annular portion 62 is recessed inward on the side near the axis to form a first positioning structure 621, and the bottom of the annular portion 62 is recessed inward on the side away from the axis to form a second positioning structure 622. The annular portions 62 on the inner and outer sides are joined together by the first positioning structure 621 and the second positioning structure 622.

[0034] Finally, protrusions 63 and locking holes 64 are respectively provided on the top of the first positioning structure 621 and the second positioning structure 622. The locking holes 64 on adjacent sides are inserted into the protrusions 63 and fixed by friction.

[0035] In this embodiment, the first positioning structure 621 and the second positioning structure 622 are identical in structure and are arranged relative to each other. Specifically, as shown in the figure... Figure 6 As shown, the positioning structure includes a recess and a protrusion. The protrusion is located inside the recess. The two positioning structures are in an S-shape. The pair of annular parts 62 can close together by engaging their recesses with the protrusions of the other.

[0036] Specifically, the multiple filter elements 61 are arranged in an inner and outer manner, so that if the innermost filter element 61 becomes clogged, it can be disassembled individually without affecting the normal operation of the equipment, which helps to reduce the downtime of the equipment.

[0037] It should be added that the filter element 61 is a cylindrical filter screen, the annular part 62 is preferably made of a material with deformation ability such as rubber or plastic, the protrusion 63 is integrally formed with the annular part 62, and the diameter of the protrusion 63 is slightly larger than the locking hole 64. So when the protrusion 63 and the locking hole 64 are inserted, they can be closed together by friction.

[0038] Of course, to further improve the fastening between the pair of annular portions 62, a protruding structure can also be provided on the top of the protruding post 63. When the protruding structure is inserted into the locking hole 64, it will abut against each other and slide by means of abutting deformation, so that the annular portion 62 can be fixed by the protruding structure.

[0039] Working method: During operation, several filter elements 61 are arranged in order of size, and the annular portions 62 on both sides are fixed by inserting the protrusions 63 and the locking holes 64. Then the filter elements 61 are placed in the stepped holes 42.

[0040] Then, the forming unit 2, together with the liquid supply unit 3, cold forges the electrode raw material. The formed electrode is placed on the guide plate 51 by the conveying guide plate. The motor 53 drives the connector 54 to rotate the connecting arm 55, so that the connecting arm 55 can drive the guide plate 51 to move back and forth to feed the guide post and to shake the lubricant adhering to the outer periphery of the electrode post into the collection box 4.

[0041] Finally, the lubricant is recovered through filter element 61.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
