Description

Technical Field

[0001] The present invention relates to the technical field of coating equipment, and in particular to an alignment device and an alignment method. Background Art

[0002] When slit coating is performed on the substrate, the coating liquid extruded by the coating head is uneven each time. In order to ensure the uniformity of coating by the coating head, the coating head is pre-coated on the pre-coating roller before coating the substrate to ensure the uniformity of coating. Therefore, the pre-coating effect of the coating head directly affects the coating quality of the coating head on the substrate. In order to improve the pre-coating effect of the coating head, when the coating head is pre-coating, the coating lip of the coating head needs to be directly above the highest point of the pre-coating roller, that is, the center line of the coating lip of the coating head needs to be directly above the rotation axis of the pre-coating roller. In the prior art, the operator relies on visual observation, which not only cannot ensure that the center line of the coating lip of the coating head is just above the rotating axis of the pre-coating roller, but also reduces the pre-coating effect of the coating head, thereby reducing the coating quality and yield, and even fails to meet the production requirements, resulting in defects such as substandard coating effects. In addition, there is no fixed reference standard, which requires repeated adjustments and a long debugging time, affecting the coating efficiency of the coating equipment. At the same time, it requires a high level of experience for the operator, which increases the difficulty of operation.

[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0041] The words expressing position and direction described in the present invention are all explained by taking the accompanying drawings as examples, but they can be changed as needed, and all changes are included in the protection scope of the present invention.

[0042] Reference Figures 1 to 8 The present invention provides a positioning device 1, which is used to align the coating head 3 and the pre-coating roller 21 of the coating device 100. The number of the positioning devices 1 is preferably two, and the two positioning devices 1 can be respectively arranged near the two ends of the length direction of the pre-coating roller 21, and the two positioning devices 1 can be adjusted simultaneously. The two positioning devices 1 may include a first positioning device 11 and a second positioning device 12, the pre-coating roller 21 has a first end 211 and a second end 212 in the length direction, and the first positioning device 11 and the second positioning device 12 are respectively arranged near the first end 211 and the second end 212 of the pre-coating roller 21.

[0043] Reference Figure 1 , Figure 4, the coating device 100 may include a pre-coating component 2, a coating head 3, a first bracket 4 for mounting the coating head 3, a carrier platform 5 and an adjustment component 6. The pre-coating component 2 may be arranged at one end of the carrier platform 5 in the coating direction, and the pre-coating component 2 may include a pre-coating roller 21 and a second bracket 22 for mounting the pre-coating roller 21. The second bracket 22 is a hollow rectangular parallelepiped as a whole, and the pre-coating roller 21 may be a cylinder as a whole. The extension direction of the rotation axis of the pre-coating roller 21 is preferably parallel or substantially parallel to the length extension direction of the coating head 3. The first bracket 4 is, for example, a gantry bracket, and the first bracket 4 may include a crossbeam 41 and a first column 42 and a second column 43 respectively arranged at both ends of the crossbeam 41. The crossbeam 41 is arranged above the carrier platform 5, and the coating head 3 may be arranged on the crossbeam 41. The first bracket 4 can drive the coating head 3 to move along the supporting platform 5 in the coating direction. The two adjustment components 6 can be respectively arranged near the two ends of the length direction of the pre-coating roller 21. The adjustment components 6 are used to adjust the position of the pre-coating roller 21 in the coating direction through the second bracket 22 so that the rotation axis of the pre-coating roller 21 and the center line of the coating lip 31 of the coating head 3 are parallel to each other.

[0044] In this embodiment, the carrier 5 is, for example, a marble platform, and the upper surface of the carrier 5 can be perpendicular to the direction of gravity, that is, the upper surface of the carrier 5 is parallel to the horizontal plane, and the pre-coating roller 21 and the coating head 3 can be parallel to the upper surface of the carrier 5, that is, the pre-coating roller 21 and the coating head 3 are parallel to the horizontal plane. When the inclinometer 14 is parallel to the upper surface of the carrier 5, the inclination angle of the inclinometer 14 is zero, that is, when the inclinometer 14 is installed on the upper surface of the carrier 5, the inclination angle of the inclinometer 14 is zero. In other words, the premise of using the alignment device 1 for alignment is that the carrier 5 has been adjusted to a horizontal state, and the coating head 3 and the pre-coating roller 21 are also horizontal to the carrier 5.

[0045] Reference Figure 4 , Figure 7 , Figure 8The pre-coating assembly 2 may further include a third bracket 23, the second bracket 22 may be arranged on the third bracket 23, the third bracket 23 may provide support for the second bracket 22, and the third bracket 23 may be arranged on the support platform 5. The two adjustment assemblies 6 may include a first adjustment assembly 61 and a second adjustment assembly 62, and the first adjustment assembly 61 and the second adjustment assembly 62 may be arranged respectively near the first end 211 and the second end 212 in the length direction of the pre-coating roller 21. The structures of the first adjustment assembly 61 and the second adjustment assembly 62 are preferably the same, and the first adjustment assembly 61 and the second adjustment assembly 62 may both include a fixing block 63, a connecting plate 64, a first adjusting member 65 and a second adjusting member 66, the fixing block 63 may be arranged on the third bracket 23, the connecting plate 64 may be arranged on the second bracket 22, the fixing block 63 and the connecting plate 64 may be connected by the first adjusting member 65 and the second adjusting member 66, and the first adjusting member 65 and the second adjusting member 66 may both be screws.

[0046] Reference Figure 8 , the first adjusting member 65 can be connected to one of the fixed block 63 and the connecting plate 64, and one end of the first adjusting member 65 can abut against the other of the fixed block 63 and the connecting plate 64. By adjusting the first adjusting member 65, the fixed block 63 and the connecting plate 64 can be moved away from each other. Since the position of the fixed block 63 is fixed, the connecting plate 64 can drive the second bracket 22 to move away from the fixed block 63, and then the pre-coating roller 21 can be moved away from the fixed block 63. In this embodiment, the first adjusting member 65 is connected to the fixed block 63, and the first adjusting member 65 and the fixed block 63 can be connected by threads, and one end of the first adjusting member 65 abuts against the connecting plate 64. For example, when the first adjusting member 65 is rotated clockwise, the first adjusting member 65 moves in the direction of the connecting plate 64, so that the first adjusting member 65 can push the connecting plate 64 to move away from the fixed block 63, and the connecting plate 64 drives the pre-coating roller 21 to move away from the fixed block 63.

[0047] Reference Figure 8, the second adjusting member 66 can be connected to the fixed block 63 and the connecting plate 64 at the same time. By adjusting the second adjusting member 66, the fixed block 63 and the connecting plate 64 can be brought closer to each other. Since the position of the fixed block 63 is fixed, the connecting plate 64 can drive the second bracket 22 to move closer to the fixed block 63, and then the pre-coating roller 21 can be moved closer to the fixed block 63. The second adjusting member 66 and the fixed block 63 can be connected by threads, and one end of the second adjusting member 66 can be embedded in or pass through the connecting plate 64, and the second adjusting member 66 and the connecting plate 64 can be connected by threads. For example, when the second adjusting member 66 is turned clockwise, due to the effect of the threads, the connecting plate 64 is pulled closer to the fixed block 63, and the connecting plate 64 drives the pre-coating roller 21 to move closer to the fixed block 63. The second adjusting member 66 can not only adjust the position of the pre-coating roller 21, but also fix the position of the connecting plate 64, thereby fixing the second bracket 22 to the third bracket 23, thereby ensuring that the position of the pre-coating roller 21 will not shake. When the adjustment of the second adjusting member 66 is completed, the position of the pre-coating roller 21 is also fixed.

[0048] In some embodiments, the adjustment component 6 only needs to be provided with one adjustment member (not shown), and the adjustment member can be a double-threaded member, that is, two sections of threads are respectively provided at both ends of the adjustment member, and the threads at both ends are respectively connected to the fixed block 63 and the connecting plate 64. When the adjustment member is rotated, the fixed block 63 and the connecting plate 64 can be close to each other or away from each other. As an example, when the adjustment member is rotated clockwise, the fixed block 63 and the connecting plate 64 can be close to each other, and when the adjustment member is rotated counterclockwise, the fixed block 63 and the connecting plate 64 can be away from each other.

[0049] Reference Figure 1 The coating device 100 may further include a driving device 7, which may be a linear motor, for example, which extends in the coating direction and may be disposed on both sides of the carrier 5. The driving device 7 is used to drive the first bracket 4 to move in the coating direction, and the first bracket 4 drives the coating head 3 to move in the coating direction. The coating device 100 may further include a guide rail 8, which extends in the coating direction and may be disposed on both sides of the carrier 5. The first bracket 4 may be slidably connected to the guide rail 8, so that the movement of the first bracket 4 is more stable. The driving device 7 may drive the first bracket 4 to move back and forth along the guide rail 8 in the coating direction.

[0050] Specifically, refer to Figure 2 , Figure 3 , Figure 6 , Figure 8, the first alignment device 11 and the second alignment device 12 may each include: an alignment base 13 and an inclinometer 14, the inclinometer 14 may be mounted on the alignment base 13, and the inclinometer 14 may be arranged parallel to the upper surface of the support platform 5. When the coating head 3 and the pre-coating roller 21 are aligned, the alignment base 13 is mounted on the pre-coating roller 21, and the alignment base 13 can be abutted against the side 32 of the coating head 3 by moving the first bracket 4 and bringing the coating head 3 close to the alignment base 13. The structures and dimensions of the two alignment bases 13 are preferably the same or substantially the same, and the two alignment bases 13 can be processed simultaneously to ensure the accuracy and consistency of the two alignment bases 13, especially to ensure the consistency of the first surface 1311 and the groove 1313 of the mounting portion 131 of the two alignment bases 13 and the contact portion 1321 of the alignment portion 132, thereby improving the alignment accuracy and precision of the coating head 3 and the pre-coating roller 21. After the coating head 3 and the pre-coating roller 21 are aligned, the first alignment device 11 and the second alignment device 12 can be removed from the pre-coating roller 21 .

[0051] Reference Figure 2 The alignment base 13 may further include a bearing portion 133, the bearing portion 133 having a third surface 1331, the third surface 1331 of the bearing portion 133 may be arranged parallel to the first surface 1311 of the mounting portion 131, and the bearing portion 133 is used to bear the inclinometer 14, that is, the inclinometer 14 may be arranged on the third surface 1331 of the bearing portion 133. The inclinometer 14 may be arranged on one side of the end of the alignment base 13 close to the pre-coating roller 21, that is, the inclinometer 14 is arranged toward the operator, so that the operator can observe the displayed value of the inclinometer 14, improve the adjustment efficiency, and shorten the debugging time.

[0052] Specifically, refer to Figure 2 , Figure 3 , Figure 6 , Figure 8 The alignment base 13 may be L-shaped as a whole, and may include a mounting portion 131 and an alignment portion 132, and the mounting portion 131 may be connected to the alignment portion 132. The mounting portion 131 may have a first surface 1311 and a second surface 1312 that are arranged opposite to each other, and the first surface 1311 of the mounting portion 131 may be planar as a whole, and the first surface 1311 of the mounting portion 131 may be provided with a groove 1313, and the mounting portion 131 may be mounted on the pre-coating roller 21 through the groove 1313, and the groove 1313 not only facilitates the mounting of the alignment on the pre-coating roller 21, but also facilitates the positioning between the alignment base 13 and the pre-coating roller 21, and prevents the alignment base 13 from falling off the pre-coating roller 21.

[0053] Reference Figure 3 , Figure 6, the groove 1313 may have a first inclined surface 13131 and a second inclined surface 13132, the first inclined surface 13131 and the second inclined surface 13132 may both be planar, and the first inclined surface 13131 and the second inclined surface 13132 may respectively form point contact with the pre-coating roller 21. The first inclined surface 13131 and the second inclined surface 13132 may also both be cambered, and the first inclined surface 13131 and the second inclined surface 13132 may match a part of the surface of the pre-coating roller 21, so that the first inclined surface 13131 and the second inclined surface 13132 may respectively form surface contact with the pre-coating roller 21. In this embodiment, the first inclined surface 13131 and the second inclined surface 13132 are both planar.

[0054] The first inclined surface 13131 and the second inclined surface 13132 are preferably symmetrically arranged. The first inclined surface 13131 and the second inclined surface 13132 may be symmetrically arranged about a center line of the groove 1313 .

[0055] The alignment portion 132 is protruding from the second surface 1312 of the mounting portion 131. A contact portion 1321 may be provided on one side of the alignment portion 132 facing the side 32 of the coating head 3. The contact portion 1321 extends toward the side 32 of the coating head 3. The contact portion 1321 is preferably provided at one end of the alignment portion 132 away from the mounting portion 131. The contact portion 1321 is used to abut against the side 32 of the coating head 3. The contact portion 1321 and the side 32 of the coating head 3 preferably form a point contact. The surface of the contact portion 1321 may be in an arc shape. Of course, the surface of the contact portion 1321 may also be in other shapes, as long as the contact portion 1321 can contact the side 32 of the coating head 3.

[0056] When in use, by adjusting the position of the pre-coating roller 21 and / or the position of the coating head 3, when the inclination angles of the two inclinometers 14 are the same, the rotation axis of the pre-coating roller 21 and the center line of the coating lip 31 of the coating head 3 are parallel to each other; when the inclination angles of the two inclinometers 14 are both preset values, the center line of the coating lip 31 of the coating head 3 is located directly above the rotation axis of the pre-coating roller 21.

[0057] Before installing the alignment device 1 to the pre-coating roller 21, place the alignment base 13 on the supporting platform 5 and install the inclinometer 14 on the base, the inclinometer 14 and the supporting platform 5 are parallel to each other at this time, and the inclinometer 14 is reset to zero, that is, when the inclinometer 14 is set horizontally, the inclination angle of the inclinometer 14 is zero. When in use, that is, when aligning the coating head 3 and the pre-coating roller 21, the two alignment devices 1 are respectively set close to the two ends of the length direction of the pre-coating roller 21, that is, the first alignment device 11 and the second alignment device 12 are respectively set close to the first end 211 and the second end 212 of the pre-coating roller 21. After the mounting portion 131 is installed on the pre-coating roller 21, the mounting portion 131 can rotate along the circumference of the pre-coating roller 21 through the groove 1313, so that the contact portion 1321 of the alignment portion 132 can abut against the side 32 of the coating head 3. By adjusting the position of the pre-coating roller 21 and / or the position of the coating head 3, when the inclination angles of the two inclinometers 14 are the same, the rotation axis of the pre-coating roller 21 and the center line of the coating lip 31 of the coating head 3 can be parallel to each other. When the inclination angles of the two inclinometers 14 are both preset values, the center line of the coating lip 31 of the coating head 3 can be located directly above the rotation axis of the pre-coating roller 21, that is, the coating head 3 is located directly above the highest point of the pre-coating roller 21.

[0058] In this embodiment, the first bracket 4 is first driven by the driving device 7 to move along the guide rail 8 toward the alignment device 1, so that the side 32 of the coating head 3 is close to the alignment device 1, and then the contact portion 1321 of the alignment portion 132 can be manually abutted against the side 32 of the coating head 3. By comparing the values ​​displayed by the two inclinometers 14, one of the inclinometers 14 is used as a reference, and the position of the pre-coating roller 21 is adjusted by the adjusting component 6, so that the values ​​displayed by the two inclinometers 14 are equal, which means that the coating head 3 and the pre-coating roller 21 are parallel to each other at this time. If the inclination angles of the two inclinometers 14 are both preset values, it means that the coating head 3 is located directly above the highest point of the pre-coating roller 21 at this time. If the inclination angles of the two inclinometers 14 are equal and not preset values, the first bracket 4 can be driven by the driving device 7 to drive the coating head 3 to move until the inclination angles of the two inclinometers 14 are both preset values, which means that the coating head 3 is located directly above the highest point of the pre-coating roller 21 at this time. During the alignment process, the groove 1313 of the mounting portion 131 is always connected to the pre-coating roller 21. In some embodiments, when the inclination angles of the two inclinometers 14 are equal and not the preset value, the position of the pre-coating roller 21 can also be adjusted by adjusting the component 6 so that the inclination angles of the two inclinometers 14 are both the preset value, so that the coating head 3 is located directly above the highest point of the pre-coating roller 21.

[0059] In the present application, by arranging the inclinometer 14 on the alignment base 13, the inclination angle of the inclinometer 14 can be used as a reference standard during adjustment, that is, the inclinometer 14 digitizes the position between the pre-coating roller 21 and the coating head 3, and the position between the pre-coating roller 21 and the coating head 3 can be judged by the visualized inclinometer 14. That is, the position of the pre-coating roller 21 and the coating head 3 are adjusted according to the difference in the inclinometer angles and the readings of the two inclinometers 14, which not only improves the alignment between the coating head 3 and the pre-coating roller 21, but also improves the alignment between the coating head 3 and the pre-coating roller 21. The accuracy can ensure that the coating lip 31 of the coating head 3 is directly above the highest point of the pre-coating roller 21, that is, it ensures that the center line of the coating lip 31 of the coating head 3 is directly above the rotation axis of the pre-coating roller 21, thereby improving the pre-coating effect of the coating head 3, thereby improving the coating quality of the coating head 3 on the substrate, and greatly shortening the debugging time, avoiding the shutdown of the coating equipment 100 due to the alignment of the coating head 3 and the pre-coating roller 21, thereby improving the coating efficiency of the coating equipment 100, and at the same time reducing the difficulty of debugging and reducing the experience requirement for the operator.

[0060] As a preferred embodiment, the mounting portion 131 and the alignment portion 132 can be arranged perpendicularly to each other, or the mounting portion and the alignment portion 132 can be arranged non-perpendicularly. In the present embodiment, the mounting portion 131 and the alignment portion 132 are arranged perpendicularly to each other, and in the direction perpendicular to the rotation axis of the pre-coating roller 21, the distance from the center line of the groove 1313 to the contact point where the contact portion 1321 contacts the side 32 of the coating head 3 is equal to the distance from the center line of the coating lip 31 of the coating head 3 to the side 32 of the coating head 3. When the mounting portion 131 and the alignment portion 132 are arranged perpendicularly to each other, the contact point where the contact portion 1321 contacts the side 32 of the coating head 3 is the front end point of the contact portion 1321 facing the side 32 of the coating head 3, that is, the distance from the center line of the groove 1313 to the front end point of the contact portion 1321 facing the side 32 of the coating head 3 is equal to the distance from the center line of the coating lip 31 of the coating head 3 to the side 32 of the coating head 3. The equality in this application refers to being within the allowable error range, such as within an error of ±10%, and is not absolutely equal.

[0061] When the mounting portion 131 and the alignment portion 132 are arranged perpendicular to each other, by adjusting the position of the pre-coating roller 21 and / or the position of the coating head 3, when the preset values ​​of the inclination angles of the two inclinometers 14 are both zero, the center line of the coating lip 31 of the coating head 3 and the center line of the groove 1313 are both located directly above the rotation axis of the pre-coating roller 21.

[0062] As a preferred method, refer to Figure 6A protective member 15 may be provided on the second surface 1312 of the mounting portion 131. The protective member 15 may be in the shape of a flat plate as a whole. The protective member 15 is disposed toward the coating head 3 and is used to prevent the coating head 3 from colliding with the mounting portion 131. The protective member 15 is preferably made of a soft material, so that the coating head 3 can be prevented from colliding with the mounting portion 131 and being damaged, thereby extending the service life of the coating head 3.

[0063] Reference Fig. 9 The present invention also provides an alignment method, using two alignment devices 1 as described above to align the coating head 3 and the pre-coating roller 21 of the coating device 100, including: steps S10 to S30.

[0064] Step S10: Install two alignment devices 1 close to both ends of the pre-coating roller 21 in the length direction.

[0065] Specifically, step S10 may include: step S11 - step S12.

[0066] Step S11: Place the two alignment bases 13 on the leveled supporting platform 5, the supporting portion 133 of the alignment base 13 can be parallel to the supporting platform 5, and then install the two inclinometers 14 on the supporting portions 133 of the two alignment bases 13 respectively, and reset the two inclinometers 14 to zero.

[0067] Step S12: Install the first alignment device 11 and the second alignment device 12 close to the first end 211 and the second end 212 of the pre-coating roller 21 in the length direction, respectively, and the grooves 1313 of the first alignment device 11 and the second alignment device 12 are respectively arranged to fit the first end 211 and the second end 212 of the pre-coating roller 21 in the length direction.

[0068] Step S20 : ​​moving the first bracket 4 to drive the coating head 3 to move toward the contact portion 1321 of the alignment portion 132 , so that the contact portion 1321 of the alignment portion 132 abuts against the side surface 32 of the coating head 3 .

[0069] Specifically, the driving device 7 is used to drive the first bracket 4 to move toward the alignment device 1 along the guide rail 8 in the coating direction, and the first bracket 4 can drive the coating head 3 to move toward the alignment device 1 in the coating direction until the side 32 of the coating head 3 and the contact portion 1321 of the alignment portion 132 are close to each other, and then the two alignment bases 13 are manually rotated respectively so that the contact portions 1321 of the two alignment bases 13 are close to the side 32 of the coating head 3 and abut against the side 32 of the coating head 3.

[0070] Step S30: adjusting the position of the pre-coating roller 21 in the coating direction through the adjusting component 6, and / or adjusting the position of the coating head 3 in the coating direction through the first bracket 4, so that the inclination angles of the two inclinometers 14 are both preset values.

[0071] Specifically, step S30 may include: step S31 - step S32.

[0072] Step S31: By comparing the displayed values ​​of the two inclinometers 14, taking one of the inclinometers 14 as a reference, the position of the pre-coating roller 21 in the direction of the coating head 3 is adjusted by the first adjusting member 65 and the second adjusting member 66 of the adjustment assembly 6 until the inclination angle of the inclinometer 14 of the second alignment device 12 is equal to the inclination angle of the inclinometer 14 of the first alignment device 11.

[0073] As an example, taking the inclinometer 14 of the first alignment device 11 as a reference, when the inclination angle of the inclinometer 14 of the second alignment device 12 is greater than the inclination angle of the inclinometer 14 of the first alignment device 11, the second end 212 of the pre-coating roller 21 can be moved in a direction away from the fixed block 63 by rotating the first adjusting member 65 of the second adjusting assembly 62 until the inclination angle of the inclinometer 14 of the second alignment device 12 is equal to the inclination angle of the inclinometer 14 of the first alignment device 11. When the inclination angle of the inclinometer 14 of the second alignment device 12 is less than the inclination angle of the inclinometer 14 of the first alignment device 11, the second end 212 of the pre-coating roller 21 can be moved in a direction close to the fixed block 63 by rotating the second adjusting member 66 of the second adjusting assembly 62 until the inclination angle of the inclinometer 14 of the second alignment device 12 is equal to the inclination angle of the inclinometer 14 of the first alignment device 11. When the adjustment of the second adjusting member 66 of the second adjusting assembly 62 is completed, the position of the pre-coating roller 21 is fixed. When the inclination angle of the inclinometer 14 of the second alignment device 12 is equal to the inclinometer 14 of the first alignment device 11, it means that the coating head 3 and the pre-coating roller 21 are parallel to each other. During the adjustment process, the contact portions 1321 of the two alignment portions 132 always abut against the side surface 32 of the coating head 3, and the grooves 1313 of the two mounting portions 131 are always arranged in contact with the pre-coating roller 21.

[0074] Step S32: The first bracket 4 is driven by the driving device 7 to drive the coating head 3 to move in the coating direction until the inclination angles of the two inclinometers 14 are both preset values, which means that the coating head 3 is located directly above the highest point of the pre-coating roller 21, that is, the center line of the coating lip 31 of the coating head 3 can be located directly above the rotation axis of the pre-coating roller 21. When the mounting portion 131 and the alignment portion 132 are arranged perpendicular to each other, the first bracket 4 is driven by the driving device 7 to drive the coating head 3 to move in the coating direction until the preset values ​​of the inclination angles of the two inclinometers 14 are both zero, which means that the coating head 3 is located directly above the highest point of the pre-coating roller 21, that is, the center line of the coating lip 31 of the coating head 3 and the center line of the groove 1313 can both be located directly above the rotation axis of the pre-coating roller 21.

[0075] As an example, the mounting portion 131 and the alignment portion 132 are arranged perpendicular to each other. When the inclination angle of each inclinometer 14 is greater than zero, the mounting portion 131 is tilted upward as a whole, and the driving device 7 can be used to drive the coating head 3 to move in a direction away from the contact portion 1321 until the inclination angles of the two inclinometers 14 are both zero. When the inclination angle of each inclinometer 14 is less than zero, the mounting portion 131 is tilted downward as a whole, and the driving device 7 can be used to drive the coating head 3 to move in a direction close to the contact portion 1321 until the inclination angles of the two inclinometers 14 are both zero. The position of the driving device 7 at this time can be recorded by the controller (not shown) of the coating device 100. Each time the coating head 3 needs to be pre-coated, the controller can control the driving device 7 to move the coating head 3 to a preset position, which can ensure that the driving device 7 can move the coating head 3 to just above the highest point of the pre-coating roller 21. During the adjustment process, the contact portions 1321 of the two alignment portions 132 are always in contact with the side surface 32 of the coating head 3 , and the grooves 1313 of the two mounting portions 131 are always in contact with the pre-coating roller 21 .

A person skilled in the art may change, modify, substitute and modify the above embodiments within the scope of the invention without departing from the principles and purpose of the present invention.
