Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, and in particular relates to a winding device and a coating equipment. Background Technology

[0002] In battery production, due to the relatively long length of the battery electrodes, they typically need to be wound into film rolls for easy storage and subsequent production processes. However, during the winding process, uneven tension and fluctuations in areal density can cause bulges. Severe bulges can lead to inward shrinkage and wrinkling of the electrode tabs, as well as abnormalities such as bubbles on the film surface after rolling, which significantly impact the product yield and production efficiency of subsequent processes.

[0003] In existing technologies, operators typically rely on real-time visual observation of the raised marks to determine whether feedback to the coating machine operator is needed for adjustment, which has low reliability. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a winding device and a coating equipment to solve these problems.

[0005] In view of this, the present invention provides a winding device, including a base frame and a control module, and further comprising:

[0006] A drum, which is rotatably mounted on a base frame;

[0007] An ultrasonic thickness measuring mechanism is mounted on a base frame and can be moved along a first direction to detect the thickness of a film roll on a scanning roll.

[0008] The first transmission mechanism is mounted on the base frame and is used to control the ultrasonic thickness measuring mechanism to move back and forth along the first direction.

[0009] Both the ultrasonic thickness measuring mechanism and the first transmission mechanism are connected to the control module via signals.

[0037] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0039] Example 1:

[0040] This embodiment provides a winding device, including a base frame 1 and a control module, and further including:

[0041] Drum 2 is rotatably mounted on base frame 1;

[0042] The ultrasonic thickness measuring mechanism 3 is movable along the first direction X and is mounted on the base frame 1 to detect the thickness of the film roll on the scanning roll 2.

[0043] The first transmission mechanism 4 is mounted on the base frame 1 and is used to control the ultrasonic thickness measuring mechanism 3 to move back and forth along the first direction X.

[0044] The control module is connected to the ultrasonic thickness measuring mechanism 3 and the first transmission mechanism 4 via signals.

[0045] Furthermore, it also includes a display module, which is used to display the thickness data map detected and scanned by the ultrasonic thickness measuring mechanism 3.

[0046] Furthermore, it also includes two fixed clamps 5, and the two ends of the drum 2 are rotatably connected to the base frame 1 through the two fixed clamps 5 respectively.

[0047] In this technical solution, two fixed clamps 5 are rotatably mounted on the base frame 1. The two ends of the roll 2 are respectively connected and fixed to the two clamps. A motor drives the fixed clamps 5 to rotate, thereby rotating the roll 2 to achieve the electrode winding operation. An ultrasonic thickness measuring mechanism 3 is movable along the first direction X and mounted on the base frame 1, perpendicular to the roll 2. During the rotation of the roll 2 to wind the electrode into a film roll, the operation control module causes the first transmission mechanism 4 to control the ultrasonic thickness measuring mechanism 3 to move along the first direction X. The ultrasonic thickness measuring mechanism 3 performs real-time scanning and detection of the film roll on the roll 2 and records the cumulative thickness data. Based on the cumulative thickness data, the severity of the bulges on the film roll is analyzed. When the severity of the bulges reaches the warning value, an alarm will sound and the machine will stop, reminding on-site personnel to cut the roll in advance and adjust the winding thickness in a timely manner.

[0048] It should be noted that the severity of the dent refers to the degree of protrusion of the maximum cumulative thickness value in the cumulative thickness data graph. The warning value for the severity of the dent can be reasonably set according to different electrode film rolls in the actual production process.

[0049] Furthermore, the display module is an LCD, and the control module is a programmable logic controller (PLC). The cumulative thickness data is displayed on the LCD. The winding device starts operating, and the roll 2 rotates to wind up the electrode sheet. At the same time, the PLC controls the first transmission mechanism 4 to drive the ultrasonic thickness measuring mechanism 3 to reciprocate along the first direction X on the base frame 1, thereby enabling real-time scanning and detection of the thickness of the film roll on the roll 2 at various time periods, and then displaying the cumulative thickness data on the LCD.

[0050] The severity of bulges on the film roll is analyzed based on the displayed cumulative thickness data chart to determine whether pre-cutting is necessary. When the bulge severity (maximum cumulative thickness value) on the cumulative thickness data chart exceeds the warning threshold, the PLC will also trigger an alarm function to remind on-site personnel to adjust the winding thickness in a timely manner and pre-cut the roll to reduce abnormal losses.

[0051] Example 2:

[0052] This embodiment provides a winding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0053] Furthermore, the first transmission mechanism 4 includes:

[0054] The first lead screw module 41 is mounted on the base frame 1 and is used to control the ultrasonic thickness measuring mechanism 3 to move back and forth along the first direction X.

[0055] Drive motor 42 is used to drive the first lead screw module 41 to move.

[0056] Furthermore, it also includes:

[0057] The second transmission mechanism 6 connects the first transmission mechanism 4 to the base frame 1.

[0058] The second transmission mechanism 6 is used to adjust the position of the first transmission mechanism 4 in the second direction Y.

[0059] Furthermore, the second transmission mechanism 6 includes:

[0060] The second lead screw module 61 is mounted on the first lead screw module 41.

[0061] The first control knob 62 is used to drive the second lead screw module 61 to move.

[0062] Furthermore, it also includes:

[0063] The third transmission mechanism 7 and the second transmission mechanism 6 are connected to the base frame 1 through the third transmission mechanism 7;

[0064] The third transmission mechanism 7 is used to adjust the position of the second transmission mechanism 6 in the third direction Z.

[0065] Furthermore, the third transmission mechanism 7 includes:

[0066] The third lead screw module 71, and the second lead screw module 61 are mounted on the third lead screw module 71;

[0067] The second control knob 72 is used to drive the third lead screw module 71 to move.

[0068] In this technical solution, the first transmission mechanism 4 can be composed of a drive motor 42 and a first lead screw module 41. The ultrasonic thickness measuring mechanism 3 is installed on the first lead screw module 41. The drive motor 42 drives the first lead screw module 41 to move, thereby driving the ultrasonic thickness measuring mechanism 3 to move back and forth smoothly along the first direction X, so as to realize the thickness measurement of the film roll on the lower roll 2.

[0069] The second transmission mechanism 6 can be composed of a second lead screw module 61 and a first control knob 62. The first lead screw module 41 is mounted on the second lead screw module 61. By rotating the first control knob 62, the lead screw of the second lead screw module 61 is controlled to rotate, thereby driving the first lead screw module 41 to move in the second direction Y, thereby realizing the position adjustment of the ultrasonic thickness measuring mechanism 3 in the second direction Y.

[0070] The third transmission mechanism 7 can be composed of a third lead screw module 71 and a second control knob 72. The second lead screw module 61 is installed on the third lead screw module 71. By rotating the second control knob 72, the lead screw of the third lead screw module 71 is controlled to rotate, thereby driving the second lead screw module 61 to move in the third direction Z, thereby realizing the position adjustment of the ultrasonic thickness measuring mechanism 3 in the third direction Z.

[0071] In addition, both the second transmission mechanism 6 and the third transmission mechanism 7 include a locking knob 9. The locking knob 9 is used to lock and fix the first control knob 62 and the second control knob 72 to prevent the first control knob 62 and the second control knob 72 from being accidentally touched, which would affect the position of the ultrasonic thickness measuring mechanism 3.

[0072] In summary, the second transmission mechanism 6 allows for fine-tuning of the position of the ultrasonic thickness measuring mechanism 3 in the second direction Y, ensuring that the ultrasonic thickness measuring mechanism 3 is always directly above the roll 2, thus guaranteeing accurate thickness measurement of the film roll on the roll 2. The third transmission mechanism 7 allows for adjustment of the position of the ultrasonic thickness measuring mechanism 3 in the third direction Z, ensuring a safe distance is maintained between the ultrasonic thickness measuring mechanism 3 and the roll 2.

[0073] Example 3:

[0074] This embodiment provides a winding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0075] Furthermore, the ultrasonic thickness measuring mechanism 3 includes:

[0076] The ultrasonic main unit is mounted on the base frame 1 and can be moved along the first direction X.

[0077] An ultrasonic probe is mounted on an ultrasonic transducer and is used to transmit and receive ultrasonic pulses.

[0078] In this technical solution, the ultrasonic main unit consists of three parts: a transmitting circuit, a receiving circuit, and a counting and display circuit. The transmitting circuit is responsible for generating a high-frequency electrical signal and converting it into a high-voltage pulse wave, i.e., an ultrasonic signal. The ultrasonic signal is transmitted to the membrane roll on the roller 2 through the ultrasonic probe. The receiving circuit receives the ultrasonic signal reflected back from the membrane roll on the roller 2. The ultrasonic signal is usually filtered and amplified. The counting and display circuit is responsible for processing the received signal and calculating the time difference of the ultrasonic reflected wave (i.e., the time from transmission to reception of the ultrasonic signal). Using this time difference, the thickness of the membrane roll can be calculated, and the result is displayed on the liquid crystal display.
