Description

Technical Field

[0001] The utility model relates to the technical field of pole piece production equipment, in particular to a tail glue detection mechanism for pole piece production. Background Art

[0002] With the development and maturity of new energy technologies, the application of lithium batteries is becoming increasingly widespread. The actual production process of lithium batteries involves multiple production steps, requiring multiple different production equipment to complete different production steps and ultimately achieve lithium battery production. If the equipment has a low degree of automation, multiple human workers will be required to assist in production, consuming a large amount of manpower, material resources, and time. This not only leads to high production costs for lithium batteries, but also significantly reduces production efficiency. Furthermore, manual assistance in production is prone to human contact, introducing pollution sources and reducing the production quality of lithium batteries.

[0003] For example, during electrode production, a color code is typically affixed to the end of the coil to remind users to replace the coil. When the color code appears, it indicates that the coil is nearing completion and needs to be replaced. Manual monitoring to confirm when the color code appears on the coil end requires 24 / 7 synchronization with the production line, which is quite labor-intensive. Furthermore, if the color code appears and the operator is not on site, it can easily lead to delayed coil replacement, which in turn causes production line downtime. Therefore, a device is needed that can monitor the coil around the clock and promptly identify when the color code appears on the coil. Utility Model Content

[0004] In view of the above shortcomings, the technical problem to be solved by the present invention is to provide a tail glue detection mechanism for electrode production, which is used to monitor the coil and identify the color marks appearing on the coil.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a tail glue detection mechanism for electrode production, comprising two symmetrically arranged sensor fixing components, and the electrode passes between the two sensor fixing components; both sensor fixing components are provided with sensor components, and the two sensor components are arranged in opposite directions to detect the electrode passing between the two sensor fixing components and the color of the electrode tail glue color code.

[0007] As a preferred solution of the present invention, a flat mounting groove is formed on the outer circumferential surface of the fixing rod and is arranged along the length direction of the fixing rod.

[0008] As a preferred solution of the present invention, a plurality of mounting holes equidistantly arranged along the length direction of the fixing rod are formed in the mounting flat groove.

[0009] As a preferred solution of the present invention, the sensor fixing assembly further includes a sensor fixing bracket, the sensor fixing bracket is fixed on the outer circumferential surface of the fixing rod, and the sensor assembly is mounted on the sensor fixing bracket.

[0010] As a preferred solution of the present invention, the sensor fixing bracket includes a color mark sensor fixing bracket and a through-beam photoelectric sensor fixing bracket, and the color mark sensor fixing bracket and the through-beam photoelectric sensor fixing bracket are arranged in parallel along the length direction of the fixing rod.

[0011] As a preferred solution of the present invention, a first mounting slot is formed on one end of the color mark sensor fixing bracket connected to the fixing rod, and a second mounting slot is formed on one end of the through-beam photoelectric sensor fixing bracket connected to the fixing rod.

[0012] As a preferred solution of the present invention, the color mark sensor fixing frame and the through-beam photoelectric sensor fixing frame are both L-shaped structures.

[0013] As a preferred solution of the present utility model, the sensor assembly includes a color mark sensor and a through-beam photoelectric sensor, and the color mark sensor and the through-beam photoelectric sensor located on the same sensor fixing assembly are electrically connected; the color mark sensors located on different sensor fixing assemblies are arranged oppositely, and the through-beam photoelectric sensors located on different sensor fixing assemblies are arranged oppositely.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: by respectively arranging sensor assemblies on two sensor fixing assemblies, the two sensor assemblies monitor whether there is a pole piece passing between the two sensor assemblies, and monitor the color of the pole piece tail glue color mark to obtain the remaining status of the roll material; at the same time, the two sensor assemblies arranged on the two sensor fixing assemblies can monitor the front and back sides of the pole piece, and there is no need to limit the forward and reverse installation directions and the forward and reverse travel directions of the roll material, thereby avoiding the situation where the single sensor assembly cannot detect the roll material color mark due to the mismatch between the roll material installation direction and the setting position of the single sensor assembly.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0020] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements described without departing from the scope of the present application. Various examples may appropriately omit, replace, or add various processes or components. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted, or combined. In addition, features described in some examples may be combined in other examples.

[0021] See also Figure 1 , Figure 1 The figure shows a schematic diagram of a tail glue detection mechanism for electrode production provided by an embodiment of the present application. Figure 1 As shown, a tail glue detection mechanism for electrode production includes two symmetrically arranged sensor fixing components 1, and the electrode passes through the two sensor fixing components 1; each of the two sensor fixing components 1 is provided with a sensor component 2, and the two sensor components 2 are arranged in opposite directions to detect the electrode passing between the two sensor fixing components 1 and the color of the electrode tail glue color code.

[0022] Specifically, the sensor fixing assembly 1 is mounted on an external frame, with a gap formed between the two sensor fixing assemblies 1 for the electrode to pass through. The plane formed by the two symmetrically arranged sensor fixing assemblies 1 is perpendicular to the electrode's travel surface, preventing the electrode from scraping against the sensor fixing assembly 1 or the sensor assembly 2 mounted thereon, which could damage the electrode surface. The two sensor assemblies 2, mounted on the two sensor fixing assemblies 1, can simultaneously monitor the front and back sides of the electrode, eliminating the need to specify the forward and reverse installation directions or forward and reverse travel directions of the web. This prevents a single sensor assembly 2 from failing to detect the color mark on the web due to a mismatch between the web's installation direction and the location of a single sensor assembly 2.

[0023] Preferably, the sensor fixing assembly 1 includes a fixing support 1-1, a fixing rod 1-2 and a sensor fixing bracket 1-3; the sensor fixing assembly 1 is installed on the electrode production equipment through the fixing support 1-1, so that the sensor fixing assembly 1 is located on the travel path of the electrode; the fixing rod 1-2 is fixed on the fixing support 1-1, and the length of the fixing rod 1-2 is greater than the width of the electrode; the sensor fixing bracket 1-3 is fixed on the outer circumference of the fixing rod 1-2, and the sensor assembly 2 is installed on the sensor fixing bracket 1-3 and faces the electrode.

[0024] Preferably, a mounting flat groove 1-21 is formed on the outer circumferential surface of the fixing rod 1-2 and is arranged along the length direction of the fixing rod 1-2. The sensor fixing bracket 1-3 fits in the mounting flat groove 1-21, which is convenient for positioning the sensor fixing bracket 1-3 when the sensor fixing bracket 1-3 is installed on the fixing rod 1-2; a plurality of mounting holes 1-22 are formed in the mounting flat groove 1-21, and the sensor fixing bracket 1-3 is fixed on the fixing rod 1-2 through the mounting holes 1-22; at the same time, since the mounting holes 1-22 are equidistantly arranged along the length direction of the fixing rod 1-2, the position of the sensor fixing bracket 1-3 on the fixing rod 1-2 can be changed by changing the mounting holes 1-22 that match the sensor fixing bracket 1-3, so as to facilitate monitoring of pole pieces of different widths.

[0025] Preferably, the sensor fixing bracket 1-3 includes a color mark sensor fixing bracket 1-31 and a through-beam photoelectric sensor fixing bracket 1-32. The color mark sensor fixing bracket 1-31 and the through-beam photoelectric sensor fixing bracket 1-32 are arranged parallel to the length direction of the fixing rod 1-2 to ensure that the color mark sensor 2-1 and the through-beam photoelectric sensor 2-2 arranged on the color mark sensor fixing bracket 1-31 and the through-beam photoelectric sensor fixing bracket 1-32 are located on the same plane.

[0026] Preferably, a first mounting slot 1-311 is formed on one end of the color mark sensor fixing bracket 1-31 connected to the fixing rod 1-2, and a second mounting slot 1-321 is formed on one end of the opposing photoelectric sensor fixing bracket 1-32 connected to the fixing rod 1-2. The first mounting slot 1-311 and the second mounting slot 1-321 cooperate with the mounting hole 1-22 on the fixing rod 1-2 to fix the color mark sensor fixing bracket 1-31 on the fixing rod 1-2. At the same time, the position of the color mark sensor fixing bracket 1-31 on the fixing rod 1-2 can be adjusted by changing the position of the first mounting slot 1-311 and the second mounting slot 1-321 cooperating with the mounting hole 1-22 on the fixing rod 1-2 to adapt to different electrode widths.

[0027] Preferably, the color mark sensor fixing bracket 1-31 and the opposing photoelectric sensor fixing bracket 1-32 are both L-shaped structures; one end of the color mark sensor fixing bracket 1-31 is connected to the fixing rod 1-2, and the other end fixes the color mark sensor 2-1; one end of the opposing photoelectric sensor fixing bracket 1-32 is connected to the fixing rod 1-2, and the other end fixes the opposing photoelectric sensor 2-2.

[0028] Preferably, the sensor assembly 2 includes a color mark sensor 2-1 and a through-beam photoelectric sensor 2-2. The color mark sensor 2-1 is used to detect the color of the color mark of the electrode tail glue, and the through-beam photoelectric sensor 2-2 is used to determine whether a electrode passes between two symmetrically arranged sensor fixing assemblies 1. When a electrode passes between the two sensor fixing assemblies 1, an obstruction will be formed between the two through-beam photoelectric sensors 2-2, and the through-beam photoelectric sensor 2-2 cannot receive the signal emitted by the through-beam photoelectric sensor 2-2 set oppositely; therefore, the color mark sensors 2-1 located on different sensor fixing assemblies 1 are arranged relative to each other, and the through-beam photoelectric sensors 2-2 located on different sensor fixing assemblies 1 are arranged relative to each other. At the same time, the color mark sensor 2-1 and the opposing photoelectric sensor 2-2 located on the same sensor fixing component 1 are electrically connected, and the working state of the color mark sensor 2-1 is controlled by the opposing photoelectric sensor 2-2. When the opposing photoelectric sensor 2-2 detects that a pole piece has passed through, the color mark sensor 2-1 works synchronously to detect the color of the color mark of the tail glue of the pole piece that has passed through; when the opposing photoelectric sensor 2-2 detects that no pole piece has passed through, the color mark sensor 2-1 enters standby state to save energy consumption.
