Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the structure of the electrode sheet 300 is shown in fig. 1. Specifically, the electrode sheet production apparatus 100 is mainly used for processing the electrode material tape 200 to form an electrode sheet 300 as shown in fig. 1. Generally, the electrode strip 200 has a plurality of protruding tabs 201 at the edge thereof, the tabs 201 are spaced apart along the length direction (i.e., the y direction in fig. 1) of the electrode strip 200, and after the electrode strip 200 is cut by the electrode sheet-making apparatus 100, a notch 202 is formed on the electrode strip, and the notch 202 is located between two adjacent tabs 201.
In the related art, the electrode material strip 200 is cut to form the notch 202 mainly by using a cutting device of the electrode sheet production apparatus 100. However, because the overall length of the electrode material strip 200 is longer, when the electrode material strip 200 is cut to form the tab 201, there may be a cutting error of the tab 201 at some positions, so there may be an error in the space between two adjacent tabs 201, there is a risk of cutting the tab 201 during cutting, and since the tab 201 is not coated with an active material, the tab itself is lighter and thinner during cutting Yi Feichu, so that notch waste cut from the tab 201 is easily adhered to the slag hole of the waste, causing the slag hole to be blocked, and affecting the normal operation of the electrode sheet production apparatus 100.
Based on this, the utility model provides the electrode slice flaking equipment 100 of the battery, which can automatically avoid the position of the tab 201 on the electrode material belt 200 when the notch 202 is cut on the electrode material belt 200, thereby being beneficial to the normal operation of the electrode slice flaking equipment 100.
The technical scheme of the utility model will be further described with reference to the examples and the accompanying drawings.
Referring to fig. 2, the present utility model provides a battery electrode sheet production apparatus 100, which includes a material belt conveying device 20, a cutting device 30, a slicing device 40, a detecting device 50 and a control device. The material belt conveying device 20 is used for driving the electrode material belt 200 to move along the feeding direction and sequentially passes through the detecting device 50, the cutting device 30 and the slicing device 40. Wherein the feeding direction is the direction in which the web 200 moves in the electrode sheet production apparatus 100 of the battery (the y direction shown in fig. 2). The cutting device 30 is used for cutting the edge of the electrode material strip 200 so as to form a gap 202 between the phase tabs 201 of the electrode material strip 200. The dicing apparatus 40 is used to cut the electrode material tape 200. The detecting device 50 is disposed upstream of the cutting device 30, and the detecting device 50 is used for detecting the spacing between two adjacent tabs 201 on the electrode material strip 200. The control device is electrically connected to the detecting device 50 and the cutting device 30, and is configured to control the cutting device 30 to pause cutting the electrode material strip 200 corresponding to two adjacent tabs 201 when the detecting device 50 detects that the spacing between the two adjacent tabs 201 on the electrode material strip 200 is different from the preset spacing.
Like this, utilize controlling means can be according to the actual interval between the two adjacent utmost point ears 201 on the electrode material area 200 that detection device 50 detected to judge and set for the interval and equal, thereby whether control cutting device 30 cuts electrode material area 200, like this, can more intelligent control cutting device 30 to electrode material area 200's cutting opportunity, avoid cutting device 30 to cut the position of utmost point ears 201 on the electrode material area 200, and then can avoid the condition of the slag notch that blocks up the waste material because of the breach waste material that cuts utmost point ear 201 produced, be favorable to the normal operating of film-making equipment.
Illustratively, the electrode material tape 200 is conveyed at a constant speed by the tape conveying device 20 in the feeding direction, and the electrode material tape 200 is cut at a certain frequency by the cutting device 30, so that the notches 202 can be formed at uniform intervals on the electrode material tape 200. When the pitch of the tabs 201 is detected to be equal to the preset pitch, the cutting device 30 cuts the notch 202 without cutting the tabs 201. When the interval between the adjacent tabs 201 is detected to be different from the preset interval, this means that the interval between the adjacent tabs 201 is abnormal, and if the cutting device 30 still cuts at the original frequency, the tabs 201 may be cut. Therefore, when the length of the material tape 200 is conveyed to the position of the cutting device 30, the cutting device 30 is controlled by the control device to suspend cutting at the position corresponding to the tab 201, so that the cutting device 30 can avoid the tab 201 and the tab 201 is prevented from being cut. As the electrode material strip 200 continues to be conveyed until the detection device 50 detects that the distance between two adjacent tabs 201 is equal to the preset distance, which means that the cutting of the section of material strip 200 can be performed again, and therefore, the control device controls the cutting device 30 to resume cutting of the section of electrode material strip 200. Therefore, by adopting the scheme of the utility model, the judging and controlling process can be simplified, and the automation degree is higher.
It can be understood that a certain time is required to elapse from the detection of the portion of the material tape 200 with abnormal spacing between the tabs 201 by the detection device 50 until the material tape 200 at the portion enters the cutting device 30, that is, a certain time difference exists between the moment when the detection device 50 detects the tab 201 and the moment when the cutting device 300 is controlled to stop cutting the material tape 200, and the time difference can be flexibly adjusted according to the actual installation distance between the detection device 50 and the cutting device 30 and the feeding speed of the material tape 200. The present embodiment is not limited to specific parameter settings during actual use of the battery electrode sheet manufacturing apparatus 100.
Illustratively, the battery electrode sheet manufacturing apparatus 100 may further be provided with a frame 10, where the material belt conveying device 20, the cutting device 30, and the slicing device 40 are all disposed on the frame 10, so that the overall structure of the battery electrode sheet manufacturing apparatus 100 can be more compact, and is convenient for transportation or installation.
Alternatively, the cutting device 30 may be a punch press capable of punching the electrode strip 200 to form the gap 202; alternatively, the cutting device 30 may be a laser cutting device, and the electrode material tape 200 is cut by laser cutting to form the notch 202. Generally, the notch 202 may be V-shaped, U-shaped, etc.
Alternatively, the detection device 50 may be a CCD image detection device (charge coupled device), a laser sensor, an infrared sensor, or the like. The detection device 50 may be disposed within the frame 10 or outside the frame 10, but upstream of the cutting device 30, so that the tab 201 is detected before the web 200 reaches the cutting device 30. The control device can be a chip module such as a singlechip, a micro control unit and the like or a computer, and can be directly arranged on the frame 10 or arranged outside the frame 10 and connected with the detection device 50 and the cutting device 30 in a wired or wireless mode. In addition, the control device can be provided with a control panel so as to be convenient for an operator to operate.
In some embodiments, the control device is further electrically connected to the slicing device 40, and the control device is further configured to control the slicing device 40 to suspend cutting of the electrode material strip 200 corresponding to the two adjacent tabs 201 when the detection device 50 detects that the spacing between the two adjacent tabs 201 on the electrode material strip 200 is different from the preset spacing.
Specifically, when the interval between the adjacent tabs 201 is detected to be equal to the preset interval, the interval between the adjacent tabs 201 meets the manufacturing requirement, and at this time, the electrode material strip 200 is sliced, so that the electrode sheet 300 meeting the design requirement can be obtained, that is, the length of the electrode sheet 300 in the feeding direction and the position of the tab on the electrode sheet 300 can meet the design requirement. When the gap between the adjacent tabs 201 is detected to be different from the preset gap, the gap between the adjacent tabs 201 is abnormal, and when the part of the material belt 200 is transported to the position of the slicing device 40, the control device controls the slicing device 40 to not slice the electrode material belt, so that no battery pole piece is generated. Until the detecting device detects that the pitch of the next tab 201 is equal to the preset pitch, the control device controls the slicing device 40 to slice again, and the electrode material strip 200 of the cut part is discharged and forms a waste sheet. In this way, the length of the waste sheet is not equal to the length of the genuine electrode sheet 300, and the waste sheet can be easily distinguished from the genuine electrode sheet 300 and removed by sieving.
It can be understood that there is a certain time difference between the time when the portion of the material strip 200 with abnormal spacing between the tabs 201 is detected by the detecting device 50 and the time when the portion of the material strip 200 enters the slicing device 40, and the time difference can be flexibly adjusted according to the actual installation distance between the detecting device 50 and the slicing device 40 and the feeding speed of the material strip 200. The debugging principle is the same as that of the cutting device 30, and will not be described here again.
In some embodiments, referring to fig. 2, 3 and 6, in order to enable the electrode strip 200 to enter the strip conveying device 20 better, the battery electrode strip manufacturing apparatus 100 further includes a feeding roller 71 and a feeding plate 72, the feeding plate 72 is connected to a side of the cutting device 30 facing away from the slicing device 40, the feeding roller 71 is disposed on a side of the feeding plate 72 facing away from the cutting device 30 corresponding to the feeding plate 72, the feeding roller 71 is used for carrying the electrode strip 200, and the feeding plate 72 is disposed at an angle to the feeding direction so as to guide the electrode strip 200 to enter the cutting device 30.
Thus, both the feeding roller 71 and the main driving roller 22 can provide tension for the electrode material belt 200, so that the electrode material belt 200 is kept flat, and the feeding stability of the electrode material belt 200 is further improved. The feeding roller 71 can provide tension for the electrode material strip 200 to smoothly enter the cutting device 30 so as to improve the reliability of cutting gaps. The feeding plate 72 can provide guidance for the electrode material strip 200 during feeding, so that the electrode material strip 200 enters the cutting device 30 from different feeding angles and can keep a substantially horizontal direction, thereby avoiding the problems of bending, stacking or deflection of the electrode material strip 200 during feeding and improving the use reliability of the electrode sheet producing device 100.
In some embodiments, the feeding plate 72 includes two feeding plates 72 disposed opposite each other in a direction perpendicular to the feeding direction. Each feeding plate 72 comprises a first guide plate 721 and a second guide plate 722 which are sequentially connected, the second guide plate 722 is connected to the cutting device 30 and parallel to the feeding direction, and the first guide plate 721 is connected to one end of the second guide plate 722, which is far away from the cutting device 30, and is arranged at an angle to the feeding direction. The interval between the two first guide plates 721 is gradually reduced in the feeding direction to guide the electrode material tape 200 into between the two second guide plates 722. That is, the two first guide plates 721 are arranged in a flared manner at the end facing away from the slicing device 40 and in a necked-down manner at the end facing toward the slicing device 40. In particular, the spacing between the two second guide plates 722 is substantially equal to the spacing of the two first guide plates 721 toward the cutting device 30, so that the electrode material tape 200 can be better guided into between the two second guide plates 722.
By arranging the feeding plate 72 into the first guide plate 721 and the second guide plate 722 which are arranged at an angle, the first guide plate 721 can guide the electrode material strip 200 with a larger feeding angle to a state with a smaller included angle with the feeding direction, so that the electrode material strip 200 can smoothly enter the cutting device 30.

In some embodiments, the number of the cutting devices 30 may be two, and the two cutting devices 30 are respectively disposed along the width direction of the electrode material tape 200 to cut the two side edges of the electrode material tape 200 in the width direction. With the simultaneous operation of the two cutting devices 30, the notches 202 can be punched simultaneously for the positions on both sides of the electrode material tape 200. Thus, the notch 202 can be formed on both sides of the electrode material strip 200 in the width direction, and the corners of the cut electrode sheet 300 are chamfered, so that the cutting efficiency of the electrode sheet production apparatus 100 of the battery is improved.
