Detailed Implementation

[0045] The term "plural" in the specification and claims of this utility model means two or more. The terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] Reference Figures 1 to 3 This utility model provides a coating device, which includes: a mounting bracket 10, an unwinding mechanism 11, a distance sensor 12, and a connecting assembly 13;

[0049] The unwinding mechanism 11 is connected to the mounting bracket 10, and the unwinding mechanism 11 is used to output the roll material 20;

[0050] One end of the connecting component 13 is connected to the mounting bracket 10, and the other end is fixedly connected to the distance sensor 12;

[0051] The signal transmitting end and the signal receiving end of the distance sensor 12 are both facing the unwinding mechanism 11, wherein the connecting component 13 has at least one rotational degree of freedom and one translational degree of freedom.

[0052] like Figure 1 As illustrated, this utility model embodiment provides a coating device for the coating process in lithium battery manufacturing, capable of applying a slurry to both surfaces of a roll material 20, such as copper or aluminum foil. Since the main improvement of this application lies in the output section of the roll material 20, the coating and baking sections are existing technologies and will not be described in detail.

[0053] Specifically, in combination Figure 1 and Figure 2 As illustrated, the coating equipment of this embodiment may include a mounting bracket 10, an unwinding mechanism 11, a distance sensor 12, and a connecting assembly 13. The mounting bracket 10 is a support structure in the coating equipment used to install and connect other structural components; it can be a support frame made of welded or bolted metal profiles. The unwinding mechanism 11 is connected to the mounting bracket 10, and a roll of material 20 can be fixed onto the roll of material 20. When the unwinding mechanism 11 rotates relative to the mounting bracket 10, it drives the roll of material 20 to rotate, outputting the roll to the station where coating is required. The forward coating mechanism and the reverse coating mechanism then apply the coating paste to both the front and back surfaces of the roll, respectively.

[0054] In this embodiment of the invention, one end of the connecting component 13 is connected to the mounting bracket 10, and the other end is fixedly connected to the distance sensor 12. The distance sensor 12 can be a non-contact ultrasonic sensor or a photoelectric sensor. After the distance sensor 12 is installed, both the signal transmitting end and the signal receiving end of the distance sensor 12 face the unwinding mechanism 11. That is, after the detection signal emitted by the signal transmitting end is directed towards the unwinding mechanism 11, the reflected signal is received and processed by the signal receiving end, thereby detecting and judging the thickness of the residual material roll on the unwinding mechanism 11. Combined with the thickness of the roll material, the length of the residual roll material can be easily calculated. Based on this, it is possible to accurately determine when the residual material roll can be cut and replaced, which helps to reduce the waste of the roll material 20. In addition, the distance sensor 12 can also be a contact mechanical limit switch. When the unwinding mechanism 11 releases material and reduces the thickness of the roll to a preset value, the mechanical limit switch is triggered, forming a prompt signal that the roll material is about to be exhausted.

[0055] Combination Figure 1 and Figure 2 As illustrated, the connecting component 13 in this embodiment of the present invention is a movable component, having at least one rotational degree of freedom and one translational degree of freedom. The axis of rotation for the rotational degree of freedom is shown below. Figure 1 The Z1 axis is shown in the diagram, and the translation direction of the translational degree of freedom is as follows: Figure 1 The Z2 axis is shown in the diagram. It is understood that the rotational and translational movements achieved by the rotational and translational degrees of freedom of the connecting component 13 can also be in other directions; this embodiment of the invention does not limit this. Furthermore, with increased degrees of freedom, it is more advantageous to achieve a wider range of position adjustments for the distance sensor 12. When the width and other dimensions of the roll material 20 mounted on the unwinding mechanism 11 change, the position of the distance sensor 12 can be adaptively adjusted to ensure that the coating equipment can effectively measure the remaining material information of roll materials 20 of different specifications.

[0056] In addition, such as Figure 3 As shown, when the coating equipment is equipped with two sets of unwinding mechanisms 11, distance sensors 12 can be installed on the roll material 20 corresponding to the two sets of unwinding mechanisms 11, and each distance sensor 12 can be connected to the mounting bracket 10 through a corresponding connecting component 13, so as to measure the thickness of the corresponding roll material 20.

[0057] Therefore, in this embodiment of the present invention, the distance sensor 12 can more accurately measure the residual material of the roll material 20 on the unwinding mechanism 11. At the same time, with the help of the movable connecting component 13, the position of the distance sensor 12 can be flexibly adjusted to meet the residual material measurement requirements of roll materials 20 of different specifications. One set of coating equipment can be applied to a variety of roll materials 20 of different specifications, which can improve the applicability of the coating equipment.

[0058] Optionally, refer to Figure 2 The connecting assembly 13 includes a fixed base 131 and a linkage mechanism 132;

[0059] The fixed base 131 is connected to the mounting bracket 10, one end of the linkage mechanism 132 is hinged to the fixed base 131, and the other end of the linkage mechanism 132 is fixed to the distance sensor 12.

[0060] Specifically, in one implementation, such as Figure 2As shown, the connecting assembly 13 of this embodiment may include a fixed base 131 and a linkage mechanism 132. The fixed base 131 is used to support and fix the linkage mechanism 132 on the mounting bracket 10. The fixed base 131 is connected to the mounting bracket 10, and the fixed base 131 and the mounting bracket 10 can maintain a relatively static fixed connection, or the fixed base 131 can slide and lock on the mounting bracket 10. One end of the linkage mechanism 132 is hinged to the fixed base 131, and the hinge axis of the linkage mechanism 132 relative to the fixed base 131 is the Z1 axis shown in the figure. The linkage mechanism 132 is fixed to the distance sensor 12. In some embodiments, the distance sensor 12 is fixed to the opposite end of the linkage mechanism 132 and the fixed base 131 that are hinged. When the linkage mechanism 132 rotates around the Z1 axis, it correspondingly drives the distance sensor 12 to move within the horizontal plane XOY shown in the figure. The distance sensor 12 can be translated to different positions to make room for loading and unloading of roll materials 20 of different specifications and sizes. It can also be moved to a position that matches the roll material 20 of the corresponding specifications and sizes to accurately and effectively measure the thickness of the remaining material.

[0061] Optionally, refer to Figure 2 The mounting bracket 10 is provided with a first sliding structure 101, and the fixing seat 131 is provided with a second sliding structure 1311. The first sliding structure 101 and the second sliding structure 1311 are slidably connected, and the fixing seat 131 can slide to the target position and be fixed relative to the mounting bracket 10.

[0062] Specifically, in one implementation, such as Figure 2 As shown, the mounting bracket 10 is provided with a first sliding structure 101, and the fixing seat 131 is provided with a second sliding structure 1311. One of the first sliding structure 101 and the second sliding structure 1311 can be a guide rail, and the other can be a groove. The guide rail is embedded in the groove, and the two can slide relative to each other. For example, the first sliding structure 101 can be a guide rail protruding from the surface of the mounting bracket 10, extending in a direction parallel to the Z1 axis shown in the figure. The second sliding structure 1311 can be a groove recessed from the surface of the fixing seat 131. Through the cooperation of the groove and the guide rail, the fixing seat 131 can slide relative to the mounting bracket 10 in a direction parallel to the Z1 axis shown in the figure. When the fixing seat 131 slides to a position that does not affect the operation of the unwinding mechanism 11, screws or other parts can be used to fix the fixing seat 131 in the corresponding position to prevent it from falling freely.

[0063] Therefore, when a thicker roll of material 20 needs to be installed onto the unwinding mechanism 11, the fixing seat 131 can be slid upwards to make room for the installation of the roll of material 20. Thus, by designing the fixing seat 131 and the mounting bracket 10 as a sliding connection structure, it is also easier for the fixing seat 131, the linkage mechanism 132, and the distance sensor 12 to avoid the roll of material 20.

[0064] Optionally, refer to Figure 2 The linkage mechanism 132 includes a first link 1321 and a second link 1322;

[0065] One end of the first connecting rod 1321 is hinged to the fixed base 131, and the other end is provided with a clamping structure 13211; the second connecting rod 1322 is fixed in the clamping structure 13211.

[0066] Distance sensor 12 is fixedly connected to the second link 1322.

[0067] Specifically, in one implementation, such as Figure 2 As shown, the linkage mechanism 132 of this utility model embodiment may include two linkages, one being a first linkage 1321 and the other a second linkage 1322. One end of the first linkage 1321 is hinged to the fixed base 131, and the axis of rotation of the hinge is the Z1 axis shown in the figure. The other end of the first linkage 1321 has a clamping structure 13211. The second linkage 1322 is fixed in the clamping structure 13211 along the Z2 axis shown in the figure. At the same time, the end of the second linkage 1322 is fixedly connected to the distance sensor 12.

[0068] Combination Figure 2 As illustrated, when the first link 1321 rotates around the Z1 axis, it can cause the second link 1322 and the distance sensor 12 to swing together in the horizontal plane XOY. Switching and adjusting the horizontal position of the distance sensor 12 can avoid interference and collision with the wider roll material 20. In addition, when the position of the second link 1322 is adjusted up and down along the Z2 axis, the height position of the distance sensor 12 can be switched and adjusted, which can avoid interference and collision with the thicker roll material 20.

[0069] Optionally, refer to Figure 2 The rotation axis Z1 of the rotational degree of freedom intersects the axis L of the unwinding mechanism 11 in a non-plane, and the rotation axis Z1 is in the vertical plane. The translation axis Z2 of the translational degree of freedom is parallel to the rotation axis Z1.

[0070] Specifically, in one implementation, such as Figure 2 As shown, in this embodiment of the invention, the rotation axis Z1 of the connecting component 13 and the mounting bracket 10, which is hinged together, can intersect with the axis L of the unwinding mechanism 11 in a non-plane manner. For example, Z1 and L can be perpendicular in space. Figure 2As illustrated, the length of the fixed base 131 is parallel to the X-axis, and its end away from the mounting bracket 10 is hinged to the first connecting rod 1321. The rotation axis Z1 of both is parallel to the Z-axis. When the first connecting rod 1321 rotates around the rotation axis Z1, it causes the distance sensor 12 to move in the horizontal plane XOY to avoid the roll material 20. In addition, the translation axis Z2 of the translational degree of freedom is parallel to the rotation axis Z1. When the second connecting rod 1322 moves up and down along the Z2 axis, it causes the distance sensor 12 to move in the Z direction to avoid the roll material 20.

[0071] Optionally, refer to Figure 2 and Figure 4 The clamping structure 13211 includes a first clamping arm 13211a, a second clamping arm 13211b, and an adjusting bolt 13211c;

[0072] The first end of the first clamping arm 13211a and the first end of the second clamping arm 13211b are connected as one unit. The second end of the first clamping arm 13211a and the second end of the second clamping arm 13211b are separated by an adjustment slot 13212. A clamping hole 13213 is formed between the first clamping arm 13211a and the second clamping arm 13211b. The adjustment slot 13212 is connected to the clamping hole 13213.

[0073] The adjusting bolt 13211c passes through the second end of the first clamping arm 13211a, the adjusting slot 13212, and the second end of the second clamping arm 13211b. The adjusting bolt 13211c is used to fix the first clamping arm 13211a and the second clamping arm 13211b together.

[0074] Specifically, in one implementation, such as Figure 2 and Figure 4 As shown, the first connecting rod 1321 in this embodiment of the present invention can be a rod-shaped part formed in one piece, with a hinge hole at one end for connecting to the fixed base 131, and a clamping structure 13211 at the other end for fixing and connecting the second connecting rod 1322. Combined with... Figure 4 As illustrated, the other end of the second connecting rod 1322 is separated to form a first clamping arm 13211a and a second clamping arm 13211b. The first end of the first clamping arm 13211a and the first end of the second clamping arm 13211b are connected as one unit. The portion separating the second end of the first clamping arm 13211a and the second end of the second clamping arm 13211b forms an adjusting slot 13212. Furthermore, a clamping hole 13213 is formed between the first clamping arm 13211a and the second clamping arm 13211b, and the adjusting slot 13212 communicates with the clamping hole 13213.

[0075] After the second connecting rod 1322 passes through the clamping hole 13213, the adjusting bolt 13211c is then passed through the second end of the first clamping arm 13211a, the adjusting slot 13212, and the second end of the second clamping arm 13211b. Tightening the adjusting bolt 13211c will reduce the gap in the adjusting slot 13212, thus clamping and fixing the second connecting rod 1322. When it is necessary to adjust the position of the second connecting rod 1322, the adjusting bolt 13211c is loosened in the opposite direction to increase the gap in the adjusting slot 13212, allowing the second connecting rod 1322 to move up and down easily and flexibly.

[0076] Optionally, refer to Figure 2 The distance sensor 12 includes a sensor base 121;

[0077] The sensor base 121 is provided with a strip hole 1211, and a tightening bolt 122 is connected to each end along the length of the strip hole 1211;

[0078] The end of the second connecting rod 1322 near the unwinding mechanism 11 extends into the strip hole 1211, and the two tightening bolts 122 clamp and fix the second connecting rod 1322.

[0079] Specifically, in one implementation, such as Figure 2 As shown, the distance sensor 12 of this utility model embodiment includes a sensor base 121, with a strip-shaped hole 1211 on the sensor base 121. The end of the second connecting rod 1322 near the unwinding mechanism 11 extends into the strip-shaped hole 1211. When the sensor base 121 and the second connecting rod 1322 are not yet fastened, the two can move relative to each other along the length direction of the strip-shaped hole 1211, thereby further adjusting the position of the distance sensor 12.

[0080] Combination Figure 2 As illustrated, once the distance sensor 12 is positioned correctly, the second connecting rod 1322 can be clamped from both sides via the tightening bolts 122 at both ends of the strip hole 1211, thus fixing the distance sensor 12 to the end of the second connecting rod 1322. It can be understood that when the position of the distance sensor 12 needs to be readjusted, the tightening bolts 122 on both sides can be rotated simultaneously to change the relative position of the distance sensor 12 and the second connecting rod 1322.

[0081] Optionally, refer to Figures 5 to 7 The distance sensor 12 is a laser sensor, and the distance sensor 12 also includes two pairs of laser transceivers 123;

[0082] One pair of laser transceivers 123 has their signal transmitting and receiving ends facing the surface of the roll of the unwinding mechanism 11, while the other pair of laser transceivers 123 has their signal transmitting and receiving ends facing the surface of the roll material 20.

[0083] Specifically, in one implementation, such as Figure 5 and Figure 6 As shown, the mid-range sensor 12 in this embodiment is a laser sensor. Compared to ultrasonic sensors and contact-type mechanical switches, laser sensors have higher sensitivity. For example, the detection accuracy of a commonly used ultrasonic sensor is ±3mm, while the detection accuracy of the laser sensor in this embodiment can be ±0.1mm. Therefore, the high-precision laser sensor can more accurately measure the remaining thickness of the roll material 20.

[0084] Combination Figure 7 As illustrated, the distance sensor 12 in this embodiment of the present invention may include two pairs of laser transceivers 123, each pair of laser transceivers 123 including a transmitter and a receiver. The signal transmitting and receiving ends of one pair of laser transceivers 123 face the surface of the unwinding mechanism 11, and are used to measure the distance H1 between the distance sensor 12 and the surface of the unwinding mechanism 11. The signal transmitting and receiving ends of the other pair of laser transceivers 123 face the surface of the roll material 20, and are used to measure the distance H2 between the distance sensor 12 and the surface of the roll material 20. The difference between H1 and H2 is the remaining thickness of the roll material 20.

[0085] Optionally, refer to Figure 8 The coating equipment also includes a controller 14 and a display 15;

[0086] The display 15 and the distance sensor 12 are both electrically connected to the controller 14. The controller 14 calculates the real-time remaining amount of the roll material 20 based on the real-time parameters of the distance sensor 12 and displays the real-time remaining amount through the display 15.

[0087] Specifically, in one implementation, such as Figure 8As shown, the coating equipment of this embodiment further includes a controller 14 and a display 15. The controller 14 is a control module with an internal processor for data analysis and processing, such as a PLC controller. The display 15 can be a screen fixed on the mounting bracket 10. The display 15 and the distance sensor 12 are both electrically connected to the controller 14. The distance sensor 12 can transmit the previously measured distances H1 and H2 to the controller 14. After processing and calculation, the controller 14 can display the real-time remaining amount of the roll material 20 on the display 15, allowing the operator to make a timely and intuitive judgment on whether to replace the roll material 20, so as to ensure the continuity of the production rhythm. In addition, in practical applications, the light source of the laser sensor in this embodiment can be a red semiconductor laser with a wavelength of 660nm visible light. After the laser sensor scans and obtains the distances H1 and H2, the controller 14 can display a 3D image of the roll material 20 and the unwinding mechanism 11 spool on the display 15. The area corresponding to distance H1 is displayed in blue, and the area corresponding to distance H2 is displayed in red.

[0088] Optionally, refer to Figure 9 The coating equipment also includes a drive unit 16;

[0089] The drive device 16 is fixedly connected to the mounting bracket 10, and the output end of the drive device 16 is fixedly connected to the connecting component 13. The drive device 16 is used to drive the connecting component 13 to move the distance sensor 12 to a preset position.

[0090] Specifically, in one implementation, such as Figure 9 As shown, the coating equipment of this embodiment of the present invention also includes a driving device 16, which can be fixedly connected to the mounting bracket 10, and the output end of the driving device 16 is fixedly connected to the connecting assembly 13. For example, the driving device 16 can be a device formed by a motor, a reducer, and a transmission mechanism. The rotating shaft of the motor is connected to the input shaft of the reducer, the output shaft of the reducer is connected to the driving member of the transmission mechanism, and the driven member of the transmission mechanism is connected to the fixed base 131. The transmission mechanism can convert circular motion into linear motion, so that the driving device 16 can automatically drive the connecting assembly 13 to move the distance sensor 12 to a preset position, which can avoid errors caused by manual adjustment.

[0091] Finally, it should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
