An electrode sheet coating processing and drying structure

Abstract

This utility model discloses an electrode coating processing and drying structure. A clamping mechanism holds the electrode sheet, which, with the cooperation of a trolley and a slide rail, transports the electrode sheet to the drying unit. The electrode sheet enters the heating chamber through a first clearance notch. A hot air blower stably inputs hot air into the heating chamber through a hot air inlet to complete preheating or drying. The entire drying process requires no manual operation, conforming to the trend of automation in manufacturing. This not only reduces the labor intensity of workers but also lowers the risk of workers being burned by heating equipment or electrode sheets. Furthermore, the automatically controlled trolley moves along the slide rail, effectively ensuring consistent heating time. During drying and heating, the electrode sheet and the heating chamber remain relatively stationary, ensuring uniform heating of each electrode sheet and resulting in more consistent coating quality. This effectively solves the technical problem of high labor intensity associated with manual preheating and drying in current electrode coating processing, achieving improved coating processing quality and safety.

Description

Technical Field

[0001] This utility model belongs to the technical field of electrode sheet production, and specifically relates to an electrode sheet coating processing and drying structure. Background Technology

[0002] Electrode sheets are widely used in battery and heater manufacturing and water electrolysis processes. To improve the stability of battery charge and discharge cycles, the heat transfer performance of heaters, or the electrolysis efficiency, appropriate coatings need to be brushed onto the electrode sheets to create a coating with corresponding effects on the electrode sheet surface.

[0003] Now it is necessary to... Figure 1 The electrode sheet shown is coated, and two different coatings are applied to both sides of the electrode sheet in the thickness direction. The electrode sheet 1 includes an electrode body 12, which is a long strip. One end of the electrode body extends vertically to form a transition section 13, and the free end of the transition section extends away from the other end of the electrode body and bends to form a mating section 14. The coating process of the electrode sheet includes loading, preheating, brushing, drying and unloading. Currently, preheating and drying are mostly done manually, that is, workers operate heating equipment or move the electrode sheet to expose it to hot airflow or heat radiation for a certain period of time so that the coating can be brushed on or the surface coating can be cured. This operation is not only labor-intensive and inefficient, but also makes it difficult to ensure the consistency of heating time and the uniformity of heating when manually operating heating equipment or moving the electrode sheet, which can easily lead to inconsistent coating quality. In addition, there is a risk of workers being burned by heating equipment or the electrode sheet. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide an electrode sheet coating processing and drying structure, which solves the technical problem of high labor intensity in the current electrode sheet coating processing where preheating and drying are done manually, and achieves the effect of improving coating processing quality and safety.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An electrode sheet coating processing and drying structure includes a transport unit and a drying unit. The transport unit includes a slide rail on a worktable. The drying unit is located on one side of the slide rail. A trolley that can move along the slide rail is provided on the slide rail at the drying unit. The trolley is provided with a clamping mechanism for clamping the electrode sheet.

[0007] The drying unit includes a heating box with a hot air inlet communicating with the interior. The hot air inlet is connected to an external hot air blower via an air pipe. The heating box also has a first clearance notch communicating with the interior, which allows an electrode sheet held by a clamping mechanism to move along a slide rail through the interior of the heating box.

[0008] Furthermore, the clamping mechanism adopts a two-finger rotating jaw. The two jaws of the two-finger rotating jaw extend toward the side where the drying unit is located. The two jaws of the two-finger rotating jaw are rod-shaped and parallel to each other. The opposing surfaces of the two jaws are raised to form a clamping part for clamping the electrode sheet. The end of the clamping part is V-shaped and matches the thickness of the electrode sheet to stably clamp the electrode sheet.

[0009] Furthermore, the slide rail is connected end to end in a ring and includes four straight segments and an arc segment connected in sequence. The drying unit is located outside the straight segments of the slide rail. The heating box is a cuboid. The length direction of the heating box is perpendicular to the straight segment. The first clearance notch penetrates the heating box along the width direction and extends to the end face facing the trolley in the length direction. The shape of the first clearance notch corresponds to the projection shape of the two grippers and the electrode sheet held by the two grippers in the width direction of the heating box.

[0010] Furthermore, a high-temperature solenoid valve and a manual ball valve are installed on the air pipe connecting the hot air blower and the heating box.

[0011] Furthermore, the inner side of the slide rail is provided with a ring-shaped belt that is concentric with the slide rail. Guide wheels are provided at the four arc segments on the inner side of the belt. Each guide wheel is driven by a motor. The inner side of the belt and the outer circular surface of the guide wheel are both toothed and meshed. The trolley is fixedly connected to the belt.

[0012] Furthermore, the trolley and the belt are fixedly connected by bolts. The shank of the bolt extends outward through the belt and is threaded into the trolley. A clearance groove is formed on the outer circumference of the guide wheel to allow space for the bolt head.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the electrode coating processing and drying structure described in this utility model, the clamping mechanism holds the electrode sheet and, with the cooperation of the trolley and slide rail, transports the electrode sheet to the drying unit. The electrode sheet enters the heating chamber through the first clearance notch. The hot air blower stably inputs hot air into the heating chamber through the hot air inlet to complete the drying of the coating on the surface of the electrode sheet. The entire drying process after loading does not require manual operation and is automatically driven by machinery, which is in line with the trend of automation in manufacturing. This not only reduces the labor intensity of workers but also reduces the risk of workers being burned by heating equipment or electrode sheets. In addition, the automatically controlled trolley moves along the slide rail. After the two grippers and the clamped electrode sheet enter the heating chamber through the first clearance notch, the trolley stops. During drying and heating, the electrode sheet and the heating chamber are relatively stationary, which can effectively ensure the consistency of heating time. During drying and heating, the electrode sheet and the heating chamber are relatively stationary, and the heating conditions of each electrode sheet are the same, which can make the coating quality of each electrode sheet more uniform. This can effectively solve the technical problem of high labor intensity caused by manual preheating and drying in the current electrode coating processing, and achieve the effect of improving coating processing quality and safety.

[0023] Example:

[0024] Please see Figure 2 and Figure 3An electrode sheet coating processing and drying structure includes a transport unit and a drying unit. The transport unit includes a slide rail 31 mounted on a worktable 21. The drying unit is located on one side of the slide rail 31. A trolley 32 that can move along the slide rail 31 is provided on the slide rail 31 at the drying unit. The trolley 32 is provided with a clamping mechanism for clamping the electrode sheet 1. In this embodiment, the clamping mechanism adopts a two-finger rotating gripper 4 (an existing product, i.e., a rotating finger cylinder or electric rotating finger with two grippers 43, as shown in Figure 4). The two-finger rotating gripper 4 includes a power body 41. One end of 41 is rotatably connected to a rotating table 42. The rotating table 42 integrates two gripper seats that can be retracted and opened. The two grippers 43 are designed and processed as needed and can be detachably connected to the gripper seats for clamping and flipping the electrode sheet 1. In addition, the two grippers 43 of the two-finger rotating gripper 4 extend toward the side where the drying unit is located. The two grippers 43 of the two-finger rotating gripper 4 are rod-shaped and parallel to each other. On the opposing surfaces of the two grippers 43, there are protrusions forming a clamping part 44 for clamping the electrode sheet 1. The end of the clamping part 44 is V-shaped and matches the thickness of the electrode sheet 1 to stably clamp the electrode sheet 1.

[0025] The drying unit includes a heating box 61, which has a hot air inlet 62 communicating with the interior. The hot air inlet 62 is connected to an external hot air blower (not shown in the figure) via an air pipe 63. The heating box 61 has a first clearance notch 65 communicating with the interior. The first clearance notch 65 allows the electrode sheet 1, which is held by the clamping mechanism, to move along the slide rail 31 through the interior of the heating box 61.

[0026] In the electrode coating processing and drying structure of this utility model, the clamping mechanism clamps the electrode sheet 1 and, with the cooperation of the trolley 32 and the slide rail 31, transports the electrode sheet 1 to the drying unit. The electrode sheet 1 enters the heating chamber 61 through the first clearance notch 65. The hot air blower stably inputs hot air into the heating chamber 61 through the hot air inlet 62 to complete the drying of the coating on the surface of the electrode sheet 1. The entire subsequent drying process after loading does not require manual operation and is automatically driven by machinery, which conforms to the trend of automation in manufacturing. This not only reduces the labor intensity of workers but also reduces costs. There is a risk of workers being burned by the heating equipment or electrode 1. In addition, the automatically controlled trolley 32 moves along the slide rail 31. After the two grippers and the clamped electrode 1 enter the heating box through the first clearance notch, the trolley stops. During the drying heating, the electrode 1 and the heating box are relatively stationary, which can effectively ensure the consistency of heating time and the same heating condition of each electrode 1, so that the coating quality of each electrode 1 is more uniform. It can effectively solve the technical problem of high labor intensity in the current electrode 1 coating process where preheating and drying are done manually, and achieve the effect of improving the coating processing quality and safety.

[0027] Please see Figure 2 and Figure 3The slide rail 31 is connected end to end in a ring and includes four straight segments and an arc segment connected in sequence. The drying unit is located outside the straight segments of the slide rail 31. The two grippers 43 of the two-finger rotating gripper 4 are perpendicular to the straight segments. The heating box 61 is a cuboid, and the length direction of the heating box 61 is perpendicular to the straight segment. The first clearance notch 65 penetrates the heating box 61 along the width direction and extends to the end face facing the trolley 32 in the length direction. The shape of the first clearance notch 65 corresponds to the projection shape of the two grippers 43 and the electrode sheet 1 held by the two grippers 43 in the width direction of the heating box 61. In this way, while ensuring that the two-finger rotating gripper 4 can hold the electrode sheet 1 smoothly, the area of ​​the first clearance notch 65 on each surface of the heating box 61 can be minimized, thereby reducing the leakage of hot air during preheating and drying, which is conducive to reducing energy consumption, shortening the preheating and drying time, and accelerating the coating processing progress.

[0028] Please see Figure 3 In this embodiment, the trolley 32 is driven by the following structure: a belt 33 is provided on the inner side of the slide rail 31 in a ring shape and concentric with the slide rail 31. Guide wheels 34 are provided at the four arc segments on the inner side of the belt 33. Each guide wheel 34 is driven by a motor 39. The inner side of the belt 33 and the outer surface of the guide wheel 34 are toothed and meshed. The trolley 32 is fixedly connected to the belt 33. The trolley 32 and the belt 33 are fixedly connected by bolts (not shown in the figure). The shank of the bolt passes through the belt 33 and is threadedly connected to the trolley 32. A relief groove 35 is provided on the outer surface of the guide wheel 34 to allow space for the bolt head. In this way, while improving the transmission accuracy of the belt 33, interference between the belt 33 and the trolley 32 and the transmission of the belt 33 is avoided.

[0029] Please see Figure 2 In this embodiment, a high-temperature solenoid valve 66 and a manual ball valve 67 are provided on the air pipe 63 connecting the hot air blower and the heating box 61. This means that during debugging, the air intake of the heating box 61 can be set by the manual ball valve 67, and during production and processing, the preheating and drying time can be precisely controlled by the high-temperature solenoid valve 66, which is beneficial to improving the coating processing quality.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
