Description

Technical Field

[0001] This utility model relates to the field of battery electrode testing technology, specifically to a device for automatically detecting and adjusting the thickness of the coating. Background Technology

[0002] Lead paste coating of battery electrodes is a crucial step in lead-acid battery production. In large-scale production, automated coating equipment is typically used. A common type is the extrusion coating machine, which works by using a screw or piston to force lead paste from a hopper and evenly coat it onto a continuously moving grid through nozzles. This method achieves high-speed, uniform coating, improving production efficiency and product quality stability. After coating, the electrode thickness needs to be checked. This ensures consistent battery performance and allows for timely detection of problems during the coating process, enabling adjustments to equipment and process parameters.

[0003] For example, patent document CN222418920U discloses a battery electrode thickness testing device. This device includes a sealed container and a pressure plate. The sealed container is used to place the battery electrode, and the pressure plate is placed on the upper surface of the battery electrode. The sealed container is provided with an injection port for injecting electrolyte into the sealed container. That is, external electrolyte is injected into the sealed container through the injection port. The electrolyte flows through the pressure plate to the surrounding area and seeps into the electrode, making the electrode wet. The sealed container is also provided with a sensing and measuring unit for detecting the displacement change of the pressure plate in the thickness direction of the battery electrode. That is, as the immersion time of the electrode increases, the thickness of the electrode changes and acts on the pressure plate, thereby causing the pressure plate to displace in the thickness direction. In this way, the swelling thickness of the battery electrode can be obtained by automatically sensing and measuring the thickness change of the pressure plate by the sensing and measuring unit. At the same time, the thickness change trend of the battery electrode can also be monitored in real time.

[0004] The aforementioned device can automatically sense the thickness of the battery electrode sheets, but it still has certain shortcomings: During use, the battery electrode sheets are placed horizontally on the bottom wall of a sealed container, and then a pressure plate is placed on the upper surface of the battery electrode sheets. It can be seen that the device requires time to place the battery electrode sheets into the sealed container, cannot be arranged on the same production line as the battery electrode sheet coating device, and has slow real-time feedback, affecting the efficiency of adjusting equipment and process parameters. Utility Model Content

[0005] This invention provides an automated device for detecting and adjusting the thickness of a coating, thereby solving the technical problem in the prior art where the detection device provides slow real-time feedback, which affects the efficiency of adjusting equipment and process parameters.

[0006] To solve the above problems, the device for automatically detecting and adjusting the coating thickness provided by this utility model adopts the following technical solution:

[0007] An automated device for detecting and adjusting the thickness of a coating, comprising:

[0008] A conveyor frame, used to connect the battery electrode paste coating production line, has a conveyor belt for receiving the coated battery electrodes;

[0009] A limiting assembly is mounted on the conveyor frame and located above the conveyor belt, with a gap between the limiting assembly and the conveyor belt for the battery electrode to pass through;

[0010] The detection component includes a 3D camera mounted on the upper side of the conveyor belt and a controller that is connected to the 3D camera. The 3D camera is used to take pictures of the battery electrodes and transmit the data to the controller. The controller stores reference plane height information for analysis by comparing the picture data with the reference plane height difference.

[0011] The controller signal is connected to the battery electrode coating production line for real-time feedback.

[0012] The beneficial effects of the automated detection and adjustment device for coating thickness provided by this utility model are as follows: After coating, the battery electrode sheet is transported from the production line to the conveyor frame and moves onto the conveyor belt of the conveyor frame. The stability of the battery electrode sheet can be ensured by the limiting component. Through the detection component, the 3D camera can take pictures of the battery electrode sheet and transmit them to the controller. The controller can analyze the height difference between the picture data and the reference surface. After analysis, the information can be fed back to the coating equipment in real time to facilitate the adjustment of the coating equipment's process parameters. The whole process realizes automated detection and establishes a fast response mechanism, which can provide a rapid reference for the coating equipment. It effectively solves the technical problem of slow real-time feedback of the detection device in the prior art, which affects the efficiency of adjusting the equipment and process parameters.

[0013] Furthermore, the limiting component is a pressure roller, which is arranged perpendicular to the conveyor belt. Vertical columns extending vertically are arranged on both sides of the width of the conveyor frame. The two ends of the pressure roller are rotatably mounted on the corresponding columns. The pressure roller is used to press against the battery electrode.

[0014] Furthermore, each of the columns is slidably mounted with a slider, and the end of the pressure roller is rotatably mounted on the slider. There is also a spring fitted on the column between the upper end of the column and the slider. The spring is used to press the pressure roller downward so that the pressure roller stably presses against the surface of the battery electrode.

[0015] Furthermore, the number of pressure rollers is two, and the two pressure rollers are distributed at both ends of the conveyor belt in the direction of movement.

[0016] Furthermore, the limiting component also includes a pressure plate, which is arranged perpendicular to the conveyor belt and located between two pressure rollers. The two ends of the pressure plate are fixed to both sides in the width direction of the conveyor frame, and there is also a gap between the pressure plate and the conveyor belt for the battery electrode to pass through.

[0017] Furthermore, the detection assembly includes a fixed frame mounted on a conveyor frame, the fixed frame having a housing extending into the upper side of the conveyor belt, and two 3D cameras arranged at the lower end of the housing, the two 3D cameras being used to take pictures of the two rows of battery electrodes respectively.

[0018] Furthermore, a computer for operation by an operator is arranged on the upper side of the mounting frame, and the computer constitutes the controller. Attached Figure Description

The controller stores reference surface height information for analysis by comparing the picture data with the reference surface height difference. The controller is connected to the battery electrode paste coating production line for real-time feedback.

[0029] like Figure 1 and Figure 2 As shown, the limiting component is a pressure roller 6, which is arranged vertically to the conveyor belt 2. Vertical columns 7 extending vertically are arranged on both sides of the width of the conveyor frame 1. The two ends of the pressure roller 6 are rotatably mounted on the corresponding columns 7. The pressure roller 6 is used to press against the battery electrode 3.

[0030] Specifically, each of the columns 7 is slidably mounted with a slider 8, and the end of the pressure roller 6 is rotatably mounted on the slider 8. A spring 9, fitted onto the column 7, is also located between the upper end of the column 7 and the slider 8. The spring 9 is used to press the pressure roller 6 downwards, so that the pressure roller 6 stably presses against the surface of the battery electrode 3. In other embodiments, the spring 9 can be replaced by a rubber block. Of course, in other embodiments, the pressure roller 6 can be directly rotatably mounted on the column 7, without the spring 9.

[0031] In this embodiment, there are two pressure rollers 6, which are distributed at both ends of the conveyor belt 2 in the direction of movement. In other embodiments, the number of pressure rollers 6 can be adjusted according to the actual situation, and there can be three or four.

[0032] In this embodiment, the limiting component also includes a pressure plate 10, which is arranged perpendicular to the conveyor belt 2 and located between two pressure rollers 6.

The pressure plate 10 and the conveyor belt 2 also have a gap for the battery electrode 3 to pass through.

[0033] like Figure 1As shown, the detection assembly includes a fixed frame 11 mounted on the conveyor frame 1. The fixed frame 11 has a housing 12 extending into the upper side of the conveyor belt 2. Two 3D cameras 4 are arranged at the lower end of the housing 12, and the two 3D cameras 4 are used to take pictures of the two rows of battery electrode sheets 3 respectively. A computer 5 for operation by the operator is arranged on the upper side of the fixed frame 11, and the computer 5 constitutes the controller. In this way, this device actually has the function of adjusting the coating thickness. That is, through the signal connection between the controller and the coating equipment, feedback data is transmitted in real time so that the coating equipment can adjust the process parameters and thus adjust the coating thickness.

[0034] The working principle of the automated detection and adjustment device for coating thickness provided by this utility model is as follows: After coating, the battery electrode 3 is transported from the production line to the conveyor frame 1 and moves onto the conveyor belt 2 of the conveyor frame 1. The stability of the battery electrode 3 can be ensured by the limiting component. Through the detection component, the 3D camera 4 can take pictures of the battery electrode 3 and transmit them to the controller. The controller can analyze the height difference between the picture data and the reference surface. After analysis, the information can be fed back to the coating equipment in real time to facilitate the adjustment of the process parameters of the coating equipment. The whole process realizes automated detection and establishes a fast response mechanism, which can provide a fast reference for the coating equipment.
