Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, and in particular to a leveling device for processing power battery metal sheets. Background Art

[0002] A power battery refers to a battery system used to power electric vehicles. In the battery, the positive and negative metal sheets play a vital role. They not only constitute the basic structure of the battery, but also determine the battery's working mode and performance. In addition, the metal sheets may have defects such as bending and twisting during the manufacturing or transportation process. These defects will affect the accuracy and stability of subsequent processes (such as welding, coating, etc.). Straightening and flattening treatment will be used to eliminate these defects and make the metal sheets reach a qualified state.

[0003] At present, the production method adopted is to first flatten the metal sheet through a pressing roller, and then send it to the subsequent slitting process; before that, the metal sheet will be placed in a warehouse for temporary storage, and then taken out when needed. However, when the stored metal sheet material is taken out from the warehouse, foreign matter is easily attached to the surface of the metal sheet due to the placement, such as debris or residual oil left over from the production process. These impurities will affect the subsequent processing of the metal sheet. If it is directly processed without proper cleaning, it will be embedded in the material during the subsequent flattening or forming process, resulting in a decline in product quality and affecting product production.

[0004] Therefore, in view of the above problems, it is urgent to propose a leveling device for processing power battery metal sheets that can effectively clean attached impurities. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a leveling device for processing power battery metal sheets, which can effectively clean attached impurities.

Connecting plates are rotatably arranged on the mounting shafts, and a torsion spring is arranged between the connecting plates and the adjacent mounting shafts. A cleaning roller is rotatably arranged between the front ends of the two connecting plates on the same layer, and a wiping cloth is provided around the outer surface of the cleaning roller.

[0007] More preferably, it further includes a mounting plate, a limit frame and a pulley, a mounting plate is provided between the inner two sides of the lower pressure roller frame, the limit frame is symmetrically slidably provided on the mounting plate, and a pulley is rotatably provided on the plate body of the limit frame.

[0008] More preferably, it further includes an insertion rod, the installation plate is provided with insertion holes evenly spaced apart, and the limiting frame is provided with an insertion rod adapted to the insertion holes.

[0009] More preferably, a belt is further included, and a circle of belt is wound between all the rollers of the upper pressure roller frame and the lower pressure roller frame.

[0010] More preferably, a support block is further included, and the support block is symmetrically inserted between the upper pressure roller frame and the lower pressure roller frame, and the support block abuts against the upper connecting plate on the same side.

[0011] More preferably, an inclined plate is further included, and the front end of the limiting frame is provided with an inclined plate.

[0012] More preferably, the opposite sides of the two inclined plates are in an inclined expansion state away from each other.

[0013] More preferably, the highest point of the front side plate of the support block is higher than the lowest point of the upper connecting plate on the same side, so as to be suitable for contact to form a counteracting fit between the two, and the lowest point of the front side plate of the support block remains flush with the highest point of the lower connecting plate on the same side.

[0014] The utility model has the following advantages: 1. The utility model provides a cleaning roller and a wiping cloth, which cooperate to wipe the surface impurities of the metal sheet that has not been leveled, so that the clean state of the metal sheet before processing can be guaranteed, thereby ensuring that during the leveling operation of the metal sheet, there will be no interference from attached impurities to affect the overall quality, which not only achieves effective cleaning of impurities on the surface of the metal sheet, but also effectively improves the leveling quality of the metal sheet.

DETAILED DESCRIPTION

[0021] First of all, it should be noted that in the various embodiments described, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0022] Example: A leveling device for processing power battery metal sheets, such as Figures 1-4 As shown, it includes a bracket 1, a lower pressure roller frame 2, an electric push rod 3, an upper pressure roller frame 4, a mounting shaft 5, a connecting plate 6, a cleaning roller 7, a torsion spring 8 and a wiping cloth 9. The bracket 1 serves as the basic supporting structure of the entire device. The top of the bracket 1 is provided with a lower pressure roller frame 2. The front and rear sides of the lower pressure roller frame 2 are symmetrically provided with electric push rods 3 with telescopic ends facing upwards. There are four electric push rods 3 in total. An upper pressure roller frame 4 is provided between the telescopic ends of the four electric push rods 3. The distance between the upper pressure roller frame 4 and the lower pressure roller frame 2 can be adjusted by the telescopic movement of the electric push rod 3, so as to achieve the control of the thickness of the metal sheet pressure roller. The roller frame 4 and the lower pressure roller frame 2 are both provided with mounting shafts 5 on the left and right sides, and connecting plates 6 are rotatably provided on the mounting shafts 5. A torsion spring 8 is provided between the connecting plate 6 and the adjacent mounting shaft 5, and a cleaning roller 7 is rotatably provided between the front ends of the two connecting plates 6 on the same layer. The setting of the torsion spring 8 can assist the resetting operation of the connecting plate 6, and can also provide a certain pressure to the cleaning roller 7 to ensure the cleaning effect of the metal sheet. The outer surface of the cleaning roller 7 is surrounded by a wiping cloth 9, which can be torn off the cleaning roller 7, and the impurities on the surface of the metal sheet can be directly contacted and wiped through the wiping cloth 9.

[0023] like Figure 4As shown, it also includes a mounting plate 10, a limit frame 11 and a pulley 12. A mounting plate 10 is arranged between the left and right sides of the lower pressure roller frame 2. The limit frame 11 is symmetrically slidably arranged on the mounting plate 10. The limit frame 11 is in a forward extending state as a whole, and a recess is formed at a position adjacent to the cleaning roller 7 to adapt to the shape of the cleaning roller 7. At the same time, the limit frame 11 can slide left and right on the mounting plate 10 to adjust its position. The top of the limit frame 11 is a spacer plate body, which can cooperate to limit the two sides of the moving metal sheet, and a pulley 12 is rotatably arranged on the plate body of the limit frame 11. The pulley 12 can assist the movement of the metal sheet, thereby ensuring the position of the metal sheet and the stability of the leveling operation process.

[0024] like Figure 4 As shown, it also includes an insertion rod 13, and insertion holes are evenly spaced on the mounting plate 10, and the limiting frame 11 is inserted with an insertion rod 13 adapted to the insertion hole. The setting of the insertion rod 13 can fix the position between the limiting frame 11 and the mounting plate 10.

[0025] like Figure 1 As shown, a belt 14 is also included. A circle of belt 14 is wound between all the rollers on the upper pressure roller frame 4 and the lower pressure roller frame 2, which is used to transmit power and ensure the synchronous operation of each roller. At the same time, the belt is directly in contact with the metal sheet being leveled through the belt, so that the pressure roller of the metal sheet can be subjected to more uniform force.

[0026] like Figure 3 As shown, a support block 15 is also included. The support block 15 is symmetrically inserted between the upper pressure roller frame 4 and the lower pressure roller frame 2. The highest point of the front side plate of the support block 15 is higher than the lowest point of the upper connecting plate 6 on the same side, so as to be suitable for contact to form a fit between the two, so that the support block 15 can be in contact with the upper connecting plate 6 on the same side, and can fix the position of the upper connecting plate 6 after rotation, and the lowest point of the front side plate of the support block 15 is kept flush with the highest point of the lower connecting plate 6 on the same side.

[0027] like Figure 4 As shown, an inclined plate 16 is also included. The front ends of the two limit frames 11 are each provided with an inclined plate 16. The two inclined plates 16 are in an inclined expansion state facing away from each other to one side, which can guide the entry of the metal sheet.

[0028] When it is necessary to use this device, the staff first places the device on a horizontal work surface to ensure that the bracket 1 is in a stable state, and then pushes the connecting plate 6 at the upper position upward, and the connected torsion spring 8 is deformed by the force, and then the connecting plate 6 rotates on the mounting shaft 5, thereby driving the cleaning roller 7 between the two connecting plates 6 to be synchronously lifted up, and then the staff pushes the support blocks 15 on both sides toward the direction close to the connecting plate 6, so that the support blocks 15 on both sides are respectively embedded between the two connecting plates 6 on the same side, and the upper and lower ends of the support blocks 15 are respectively against the connecting plates 6 on the upper and lower sides, thereby against the position of the upward-lifted connecting plate 6 and the cleaning roller 7 to stabilize the overall position, and then the staff performs the processing according to the need The specifications of the metal sheet are used to slide and adjust the positions of the limit frames 11 on both sides, so that the limit frames 11 can slide left and right on the mounting plate 10. After the positions of the two are adjusted, the insertion rod 13 can be inserted. The insertion rod 13 is inserted into the limit frame 11 and then enters the jack on the mounting plate 10 to fix the adjusted position of the limit frame 11. Then, one end of the metal sheet that needs to be leveled can be passed through between the cleaning rollers 7 and then between the lower pressure roller frame 2 and the upper pressure roller frame 4. Then, the support block 15 can be operated in reverse to make the upper connecting plate 6 break away from the restriction of the support block 15, and then the torsion spring 8 is reset, so that the connecting plate 6 and the cleaning roller 7 are reset, and at the same time, the cleaning roller 7 on the lower side is cooperated to clamp the metal sheet, and the cleaning roller 7 surface The wiping cloth 9 on the surface comes into direct contact with the metal sheet, and then the lower pressure roller frame 2 and the upper pressure roller frame 4 are started to operate. The metal sheet is pushed backward with the operation, and first passes between the two cleaning rollers 7. The two cleaning rollers 7 rotate accordingly, and then the impurities attached to the surface of the metal sheet are wiped and cleaned by the wiping cloth 9 to ensure that it is in a clean state before the leveling operation. Then, the limiting frames 11 on both sides are used to limit the moving metal sheet to ensure that the position of the metal sheet will not shift during the entry process and the position is in a stable state. The pulley 12 will assist in pushing the metal sheet when it enters between the limiting frames 11, and then the metal sheet will gradually enter the lower pressure roller frame 2 and the upper pressure roller frame 4 as it moves, and the electric push rod 3 is started. The drive of the electric push rod 3 adjusts the distance between the upper pressure roller frame 4 and the lower pressure roller frame 2, so as to cooperate with the rolling between the upper pressure roller frame 4 and the lower pressure roller frame 2 to level the metal sheet to the required thickness, and the belt 14 will cooperate with the operation of the upper pressure roller frame 4 and the lower pressure roller frame 2 to directly contact the metal sheet, so that the pressure roller of the metal sheet can be more evenly stressed, thereby ensuring that the metal sheet can be effectively leveled through the reciprocating pressure roller operation. In summary, the overall leveling of the battery metal sheet is completed. After the metal sheet is leveled, the electric push rod 3 can be driven to move the upper pressure roller frame 4 upward, take out the metal sheet, and then tear off the used wiping cloth 9 from the cleaning roller 7 for replacement, and the entire operation process can be completed.
