Description

Technical Field

[0001] This utility model relates to the technical field of perovskite battery manufacturing equipment, and in particular to a substrate positioning mechanism and coating equipment. Background Technology

[0002] In the fabrication process of perovskite solar cells, one step involves applying a perovskite slurry to a substrate using a coating head to form a perovskite liquid film. During the coating process, the coating head needs to continuously discharge the slurry to ensure uniform filling of the head's interior, thereby improving the uniformity of slurry discharge.

[0003] During substrate coating, if the substrate's position shifts, it may cause a misalignment between the substrate's position and the coating head's coating position, resulting in the inability to form a uniform and continuous perovskite liquid film on the substrate. Furthermore, during coating, multiple substrates move sequentially downwards towards the coating head, and the coating head coats multiple substrates sequentially. Due to the spacing between the substrates, it is difficult to maintain a uniform spacing. Large gaps between adjacent substrates can lead to a significant waste of coating paste as it is coated into these gaps. Utility Model Content

[0043] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many 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 concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0044] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0045] like Figure 1 As shown, this utility model provides a substrate positioning mechanism for positioning a substrate assembly 100 comprising multiple substrates 101. After being positioned by the substrate positioning mechanism, the substrates 101 in the substrate assembly 100 can move toward the coating head of a coating equipment for coating operations. The multiple substrates 101 in the substrate assembly 100 are arranged sequentially in a front-to-back direction, and adjacent substrates 101 can be spaced apart. The front-to-back direction of the multiple substrates 101 can be parallel to the moving direction of the substrate assembly 100 toward the coating head. In this application, the substrate positioning mechanism includes a front positioning module 1, a rear positioning module 2, a left positioning module 3, and a right positioning module 4, and may also include a mounting bracket 5.

[0046] Reference Figure 2The front positioning module 1 is used to position the front end of the substrate assembly 100. The front positioning module 1 includes a front abutment unit 11 and a first mounting plate 13, and may also include a first driving assembly 12. The front abutment unit 11 is used to abut against the front end of the substrate assembly 100 to position the front end of the substrate assembly 100. The front abutment unit 11 includes a front mounting plate 111 and a plurality of front abutment members 112 mounted on the front mounting plate 111. The plurality of front abutment members 112 can be arranged sequentially along the front contour of the substrate assembly 100. For example, the substrate assembly 100 has a rectangular structure, and the front contour of the substrate assembly 100 is the front side of the rectangular structure. The plurality of front abutment members 112 are arranged sequentially along the extension direction of the front side, and the plurality of front abutment members 112 are used to simultaneously abut against the front side of the substrate assembly 100 to perform multi-point positioning of the front side of the substrate assembly 100.

[0047] Reference Figure 3 To prevent the front abutment 112 from making hard contact with the substrate assembly 100, and to prevent damage to the front abutment 112 or the substrate assembly 100 due to the large interaction force between them, an elastic member 1121 is provided between the front abutment 112 and the front mounting plate 111 in this application. The front abutment 112 can compress the elastic member 1121 when it abuts against the substrate assembly 100, thereby achieving elastic contact between the front abutment 112 and the substrate assembly 100. This reduces the impact force when the front abutment 112 contacts the substrate assembly 100 and decreases the relative force between the front abutment 112 and the substrate assembly 100 when the front abutment 112 drives the substrate assembly 100 to a predetermined position. The front mounting plate 111 may have multiple blind holes, each of which can be used to mount one front abutment 112. An elastic element 1121 is installed in the blind hole of the front mounting plate 111. One end of the elastic element 1121 abuts against the bottom wall forming the blind hole, and the other end of the elastic element 1121 abuts against the front abutment 112 accommodated in the blind hole.

[0048] Specifically, the front abutment member 112 may include a front abutment portion 1122 protruding from the front mounting plate 111 and used to abut against the substrate assembly 100, and a front mounting portion 1123 at least partially mounted inside the front mounting plate 111. At least a portion of the front mounting portion 1123 is located within a blind hole in the front mounting plate 111 and contacts the elastic member 1121. When the front mounting portion 1123 presses against the elastic member 1121 or the elastic member 1121 rebounds to reset the front mounting portion 1123, the front mounting portion 1123 will move relative to the front mounting plate 111. To reduce the frictional force generated when the front mounting portion 1123 moves relative to the front mounting plate 111, the outer side of the front mounting portion 1123 may be a steel column bushing. Multiple rolling steel balls on the steel ball bushing contact the front mounting plate 111 to reduce the frictional force generated when the front mounting portion 1123 moves relative to the front mounting plate 111.

[0049] Reference Figure 2In the front positioning module 1, the first driving component 12 is connected to the front abutment unit 11, and the first driving component 12 is used to drive the front abutment unit 11 to move toward the substrate assembly 100, so that the front abutment member 112 in the front abutment unit 11 can abut against the substrate 101 and adjust the front end position of the substrate assembly 100, thereby achieving the positioning of the front end of the substrate assembly 100. The first driving component 12 may include a first driving cylinder 121 and a first floating joint 122. The first floating joint 122 is connected to the front mounting plate 111, for example, the first floating joint 122 is fixedly connected to the front mounting plate 111 so that the first floating joint 122 can move synchronously with the front mounting plate 111. The driving rod of the first driving cylinder 121 can be connected to the first floating joint 122 to drive the front mounting plate 111 to move through the first floating joint 122. By using the first floating joint 122 in conjunction with the first driving cylinder 121, the first driving cylinder 121 can be prevented from being damaged due to stalling. By using the first driving cylinder 121 to drive the front mounting plate 111 to move, the multiple front abutment members 112 on the front mounting plate 111 can move synchronously.

[0050] When the first drive assembly 12 drives the front abutment unit 11 to move, in order to control the moving speed of the front abutment unit 11, the first drive cylinder 121 in the first drive assembly 12 can be connected to the air supply line through the first throttle valve 123. By adjusting the first throttle valve 123, the air flow supplied to the first drive cylinder 121 is adjusted, thereby controlling the driving speed of the first drive cylinder 121 and realizing the adjustment of the moving speed of the front abutment unit 11. When the front abutment unit 11 begins to move toward the substrate group 100, the moving speed of the front abutment unit 11 can be relatively fast. When the front abutment unit 11 approaches the substrate group 100, the moving speed of the front abutment unit 11 decreases to reduce the impact force when the front abutment unit 11 contacts the substrate group 100.

[0051] The first drive assembly 12 and the front abutment unit 11 can be respectively mounted on the first mounting plate 13, so that the first drive assembly 12, the front abutment unit 11, and the first mounting plate 13 form a whole. Specifically, the first drive cylinder 121 of the first drive assembly 12 can be fixedly mounted on the first mounting plate 13, and the front abutment unit 11 can be slidably mounted on the first mounting plate 13. When the first drive cylinder 121 drives the front abutment unit 11 to move, the front abutment unit 11 can slide relative to the first mounting plate 13. Specifically, the front mounting plate 111 of the front abutment unit 11 can be provided with a slide rail, and the first mounting plate 13 is provided with a slide groove that mates with the slide rail on the front mounting plate 111. The front abutment unit 11 and the first mounting plate 13 are slidably connected through the slide rail and the slide groove.

[0052] The first mounting plate 13 can be mounted on the mounting frame 5 via the first column 131, so that the first drive assembly 12 and the front abutment unit 11 are indirectly mounted on the mounting frame 5. The first column 131 is supported between the first mounting plate 13 and the mounting frame 5 to control the distance between the first mounting plate 13 and the mounting frame 5. By controlling the length of the first column 131, the height of the front abutment unit 11 can be controlled to ensure that the front abutment member 112 of the front abutment unit 11 and the base plate assembly 100 are at the same height.

[0053] Reference Figure 4 The rear positioning module 2 is used to position the rear end of the substrate assembly 100. The rear positioning module 2 includes a rear abutment unit 21 and a first mounting plate 13, and may also include a first driving assembly 12. The structure of the rear abutment unit 21 can be similar to that of the front abutment unit 11, and the rear abutment unit 21 is used to abut against the rear end of the substrate assembly 100 to position the rear end of the substrate assembly 100. The rear abutment unit 21 includes a rear mounting plate 211 and a plurality of rear abutment members 212 mounted on the rear mounting plate 211. The plurality of rear abutment members 212 can be arranged sequentially along the rear contour of the substrate assembly 100. For example, if the substrate assembly 100 has a rectangular structure, the rear contour of the substrate assembly 100 is the rear side of the rectangular structure, and the plurality of rear abutment members 212 are arranged sequentially along the extension direction of the rear side, and the plurality of rear abutment members 212 are used to simultaneously abut against the rear side of the substrate assembly 100 to perform multi-point positioning of the rear side of the substrate assembly 100.

[0054] In the rear abutment unit 21, the rear abutment member 212 may have an elastic member 1121 disposed between it and the rear mounting plate 211. The rear abutment member 212 can compress the elastic member 1121 when it abuts against the substrate assembly 100, so that the rear abutment member 212 and the substrate assembly 100 are elastically abutted. The installation method of the elastic member 1121 corresponding to the rear abutment unit 21 is the same as the installation method of the elastic member 1121 corresponding to the front abutment unit 11, so it will not be described in detail here.

[0055] The rear abutment member 212 may include a rear abutment portion protruding from the rear mounting plate 211 for abutting against the substrate assembly 100, and a rear mounting portion at least partially mounted inside the rear mounting plate 211. At least a portion of the rear mounting portion is located within a blind hole in the rear mounting plate 211 and contacts the elastic member 1121. The outer side of the rear mounting portion may be a steel column bushing, on which a plurality of rollable steel balls are mounted to contact the rear mounting plate 211 to reduce the frictional force generated when the rear mounting portion moves relative to the rear mounting plate 211.

[0056] The first driving component 12 in the rear positioning module 2 is used to drive the rear abutting unit 21 to move toward the substrate assembly 100, so that the rear abutting member 212 of the rear abutting unit 21 can abut against the rear end of the substrate assembly 100. The first driving component 12 in the rear positioning module 2 is the same as the first driving component 12 in the front positioning module 1. In the rear positioning module 2, the first driving cylinder 121 is connected to the first floating joint 122 mounted on the rear mounting plate 211, so as to drive the rear mounting plate 211 and the rear abutting member 212 on the rear mounting plate 211 to move through the first floating joint 122; and the first driving cylinder 121 in the rear positioning module 2 can also be connected to the air supply line through the first throttle valve 123.

[0057] In the initial state, the distance between the front abutment unit 11 and the rear abutment unit 21 is greater than the length of the substrate group 100 in the front-to-back direction. When the substrate group 100 is placed in the substrate positioning mechanism, the front abutment unit 11 and the rear abutment unit 21 are driven by the corresponding first driving component 12, and the front abutment unit 11 and the rear abutment unit 21 move toward the substrate group 100, so that the distance between the front abutment unit 11 and the rear abutment unit 21 gradually changes to be the same as the length of the substrate group 100 in the front-to-back direction. At this time, the front abutment unit 11 and the rear abutment unit 21 contact the substrate group 100 to position the front and rear ends of the substrate group 100.

[0058] In other embodiments, one of the front positioning module 1 and the rear positioning module 2 includes a first driving component 12, while the other does not. For example, the rear abutment 212 remains in a fixed position, and the first driving component 12 drives the front abutment 112 to move toward the substrate assembly 100, reducing the distance between the front abutment 112 and the rear abutment 212. The distance between the front abutment unit 11 and the rear abutment unit 21 gradually changes to be the same as the length of the substrate assembly 100 in the front-rear direction and abuts against the substrate assembly 100, thereby positioning the front and rear ends of the substrate assembly 100. Alternatively, the front abutment 112 remains in a fixed position, and the first driving component 12 drives the rear abutment 212 to move toward the substrate assembly 100, reducing the distance between the rear abutment 212 and the front abutment 112. The distance between the rear abutment unit 21 and the front abutment unit 11 gradually changes to be the same as the length of the substrate assembly 100 in the front-rear direction and abuts against the substrate assembly 100, thereby positioning the substrate assembly 100 in the front-rear direction.

[0059] In the rear positioning module 2, the first driving component 12 and the rear abutment unit 21 can be respectively mounted on the corresponding first mounting plate 13, so that the first driving component 12, the rear abutment unit 21 and the corresponding first mounting plate 13 form a whole. Specifically, the first driving cylinder 121 of the first driving component 12 can be fixedly mounted on the corresponding first mounting plate 13, and the rear abutment unit 21 can be slidably mounted on the corresponding first mounting plate 13. The sliding mounting method of the rear abutment unit 21 and the corresponding first mounting plate 13 can be the same as the sliding mounting method of the front abutment unit 11 and the corresponding first mounting plate 13.

[0060] In the rear positioning module 2, the first mounting plate 13 is mounted on the mounting frame 5 via the first column 131, so that the first drive assembly 12 and the rear abutment unit 21 are indirectly mounted on the mounting frame 5. Furthermore, the first mounting plate 13 can be mounted on the mounting frame 5 via the first column 131, which supports the first mounting plate 13 between the first mounting plate 13 and the mounting frame 5 to control the distance between them, thereby ensuring that the rear abutment member 212 of the rear abutment unit 21 and the substrate assembly 100 can be at the same height.

[0061] Reference Figure 5 The left positioning module 3 is used to position the left end of the substrate group 100. The left positioning module 3 may include a left abutment unit 31, a second drive assembly 32, and a second mounting plate 33. The left abutment unit 31 can simultaneously abut the left ends of multiple substrates 101 in the substrate group 100 to simultaneously position the left ends of multiple substrates 101 in the substrate group 100.

[0062] The left abutment unit 31 includes a left mounting plate 312 and a plurality of left abutment members 313 mounted on the left mounting plate 312. The plurality of left abutment members 313 are arranged sequentially along the left side contour of the substrate group 100. For example, the substrate group 100 has a rectangular structure, and the left side contour of the substrate group 100 is the left side of the rectangular structure. The plurality of left abutment members 313 are arranged sequentially along the extension direction of the left side, and the plurality of left abutment members 313 are used to simultaneously abut against the left side of the substrate group 100 to perform multi-point positioning of the left side of the substrate group 100. Each substrate 101 in the substrate group 100 abuts against at least one left abutment member 313, so that the plurality of left abutment members 313 simultaneously abut against all substrates 101 in the substrate group 100. Preferably, the number of left abutment members 313 abutting against each substrate 101 in the substrate group 100 is the same. For example, each substrate 101 in the substrate group 100 abuts against three left abutment members 313.

[0063] The left abutment 313 can specifically be a cam follower, and the left abutment 313 is movably mounted on the left mounting plate 312. By adjusting the relative position between the left abutment 313 and the left mounting plate 312, multiple left abutments 313 can be adapted to the left side contour of the substrate assembly 100, for example, multiple left abutments 313 can be connected in a straight line. The movable mounting method of the left abutment 313 can adopt existing movable mounting methods, so it will not be described in detail here.

[0064] The left abutment unit 31 may further include a partition plate 311, which is fixedly mounted on the left mounting plate 312. The partition plate 311 is positioned between adjacent substrates 101 in the front-to-back direction and can abut against adjacent substrates 101 respectively, thereby limiting the spacing between adjacent substrates 101 in the front-to-back direction. When the substrate group 100 is placed in the substrate positioning mechanism, the partition plate 311 is located between adjacent substrates 101 in the front-to-back direction, and the partition plate 311 can be spaced apart from adjacent substrates 101. When the front abutment unit 11 and / or the rear abutment unit 21 abut against the substrate group 100, the substrates 101 in the substrate group 100 abut against the partition plate 311 under the drive of the front abutment unit 11 and / or the rear abutment unit 21, thereby making the spacing between adjacent substrates 101 the same as the thickness of the partition plate 311. By controlling the thickness of the partition plate 311, the spacing between adjacent substrates 101 can be controlled, thereby allowing multiple substrates 101 to be evenly distributed, and the spacing between adjacent substrates 101 can be a predetermined value. When the spacing between multiple substrates 101 is a predetermined value, multiple substrates 101 can be coated continuously, and the liquid curtain formed by the coating head is not interrupted, significantly reducing the waste of coating slurry.

[0065] The second driving assembly 32 is connected to the left abutment unit 31 and drives the left abutment unit 31 to move toward the substrate assembly 100, so that the left abutment member 313 in the left abutment unit 31 can abut against the substrate 101 and adjust the position of the left end of the substrate assembly 100, thereby achieving the positioning of the left end of the substrate assembly 100. The second driving assembly 32 may include a second driving cylinder 321 and a second floating joint 322. The second floating joint 322 is connected to the left mounting plate 312, for example, the second floating joint 322 is fixedly connected to the left mounting plate 312 so that the second floating joint 322 can move synchronously with the left mounting plate 312. The driving rod of the second driving cylinder 321 can be connected to the second floating joint 322 to drive the left mounting plate 312 to move through the second floating joint 322. By using the second floating joint 322 in conjunction with the second driving cylinder 321, the second driving cylinder 321 can be prevented from being damaged due to jamming. By using the second driving cylinder 321 to drive the left mounting plate 312 to move, the multiple left abutment members 313 on the left mounting plate 312 can move synchronously. At the same time, the partition plate 311 can move synchronously between adjacent substrates 101.

[0066] When the second drive assembly 32 drives the left abutment unit 31 to move, in order to control the moving speed of the left abutment unit 31, the second drive cylinder 321 in the second drive assembly 32 can be connected to the air supply line through the second throttle valve 323. By adjusting the second throttle valve 323, the air flow supplied to the second drive cylinder 321 is adjusted, thereby controlling the driving speed of the second drive cylinder 321 and realizing the adjustment of the moving speed of the left abutment unit 31. When the left abutment unit 31 begins to move toward the substrate group 100, the moving speed of the left abutment unit 31 can be relatively fast. When the left abutment unit 31 approaches the substrate group 100, the moving speed of the left abutment unit 31 decreases to reduce the impact force when the left abutment unit 31 contacts the substrate group 100.

[0067] The second drive assembly 32 and the left abutment unit 31 can be respectively mounted on the second mounting plate 33, so that the second drive assembly 32, the left abutment unit 31 and the second mounting plate 33 form a whole. The second drive cylinder 321 of the second drive assembly 32 can be fixedly mounted on the second mounting plate 33, and the left abutment unit 31 can be slidably mounted on the second mounting plate 33. When the second drive cylinder 321 drives the left abutment unit 31 to move, the left abutment unit 31 can slide relative to the second mounting plate 33. Specifically, the left mounting plate 312 of the left abutment unit 31 can be provided with a slide rail, and the second mounting plate 33 is provided with a slide groove that mates with the slide rail on the left mounting plate 312. The left abutment unit 31 and the second mounting plate 33 are slidably connected through the slide rail and the slide groove.

[0068] The second mounting plate 33 can be mounted on the mounting frame 5 via the second column 331, so that the second drive assembly 32 and the left abutment unit 31 are indirectly mounted on the mounting frame 5. The second column 331 is supported between the second mounting plate 33 and the mounting frame 5 to control the distance between the second mounting plate 33 and the mounting frame 5. By controlling the length of the second column 331, the height of the left abutment unit 31 can be controlled to ensure that the left abutment member 313 of the left abutment unit 31 and the base plate assembly 100 are at the same height.

[0069] Reference Figure 6 The right positioning module 4 is used to position the right end of the substrate group 100. The right positioning module 4 may include a right abutment unit 41, a second driving component 32, and a second mounting plate 33. The right abutment unit 41 can simultaneously abut the right ends of multiple substrates 101 in the substrate group 100 to simultaneously position the right ends of multiple substrates 101 in the substrate group 100.

[0070] The right abutment unit 41 includes a right mounting plate 411 and a plurality of right abutment members 412 mounted on the right mounting plate 411. The plurality of right abutment members 412 are arranged sequentially along the right side contour of the substrate group 100. For example, the substrate group 100 has a rectangular structure, and the right side contour of the substrate group 100 is the right side of the rectangular structure. The plurality of right abutment members 412 are arranged sequentially along the extension direction of the right side, and the plurality of right abutment members 412 are used to simultaneously abut against the right side of the substrate group 100 to perform multi-point positioning of the right side of the substrate group 100. Each substrate 101 in the substrate group 100 abuts against at least one right abutment member 412, so that the plurality of right abutment members 412 simultaneously abut against all substrates 101 in the substrate group 100. Preferably, the number of right abutment members 412 abutting against each substrate 101 in the substrate group 100 is the same, for example, each substrate 101 in the substrate group 100 abuts against three right abutment members 412.

[0071] To prevent the right abutment 412 from making hard contact with the substrate assembly 100, and to prevent damage to the right abutment 412 or the substrate assembly 100 due to the large interaction force between them, an elastic member 1121 is provided between the right abutment 412 and the right mounting plate 411 in this application. The right abutment 412 can compress the elastic member 1121 when it abuts against the substrate assembly 100, thereby achieving elastic contact between the right abutment 412 and the substrate assembly 100. This reduces the impact force when the right abutment 412 contacts the substrate assembly 100 and decreases the relative force between the right abutment 412 and the substrate assembly 100 when the right abutment 412 drives the substrate assembly 100 to a predetermined position. The right mounting plate 411 may have multiple blind holes, each of which can be used to mount one right abutment 412. An elastic element 1121 is installed in the blind hole of the right mounting plate 411. One end of the elastic element 1121 abuts against the bottom wall forming the blind hole, and the other end of the elastic element 1121 abuts against the right abutting element 412 accommodated in the blind hole.

[0072] Specifically, the right abutment member 412 may include a right abutment portion 4121 protruding from the right mounting plate 411 and used to abut against the substrate assembly 100, and a right mounting portion 4122 at least partially mounted inside the right mounting plate 411. At least a portion of the right mounting portion 4122 is located within a blind hole in the right mounting plate 411 and contacts the elastic member 1121. When the right mounting portion 4122 presses against the elastic member 1121 or the elastic member 1121 rebounds to reset the right mounting portion 4122, the right mounting portion 4122 will move relative to the right mounting plate 411. To reduce the frictional force generated when the right mounting portion 4122 moves relative to the right mounting plate 411, the outer side of the right mounting portion 4122 may be a steel column bushing. Multiple rolling steel balls on the steel ball bushing contact the right mounting plate 411 to reduce the frictional force generated when the right mounting portion 4122 moves relative to the right mounting plate 411.

[0073] The right abutment unit 41 may also include a partition plate 311, which is fixedly mounted on the right mounting plate 411. The partition plate 311 is used to be disposed between adjacent substrates 101 in the front-back direction and can abut against adjacent substrates 101 respectively, so as to limit the spacing between adjacent substrates 101 in the front-back direction.

[0074] When the substrate assembly 100 is placed in the substrate positioning mechanism, the partition plate 311 in the left abutment unit 31 can be located on the left side of the substrate assembly 100, and the partition plate 311 in the right abutment unit 41 can be located on the right side of the substrate assembly 100. Two partition plates 311 are provided between adjacent substrates 101, namely the partition plate 311 in the left abutment unit 31 and the partition plate 311 in the right abutment unit 41. The two partition plates 311 are used together to separate adjacent substrates 101. In other embodiments, only the left abutment unit 31 or only the right abutment unit 41 may include a partition plate 311, and adjacent substrates 101 may be separated by only one partition plate 311.

[0075] In the right positioning module 4, the second driving component 32 is connected to the right abutment unit 41, and the second driving component 32 is used to drive the right abutment unit 41 to move toward the substrate assembly 100, so that the right abutment member 412 in the right abutment unit 41 can abut against the substrate 101 and restrict the right end position of the substrate assembly 100, thereby achieving the positioning of the right side of the substrate assembly 100. The second driving component 32 may include a second driving cylinder 321 and a second floating joint 322. The second floating joint 322 is connected to the right mounting plate 411, for example, the second floating joint 322 is fixedly connected to the right mounting plate 411 so that the second floating joint 322 can move synchronously with the right mounting plate 411. The driving rod of the second driving cylinder 321 can be connected to the second floating joint 322 to drive the right mounting plate 411 to move through the second floating joint 322. By using the second floating joint 322 in conjunction with the second driving cylinder 321, the second driving cylinder 321 can be prevented from being damaged due to jamming. By using the second driving cylinder 321 to drive the right mounting plate 411 to move, the multiple right abutment members 412 on the right mounting plate 411 can move synchronously. At the same time, the partition plate 311 can move synchronously between adjacent substrates 101.

[0076] In the right positioning module 4, when the second drive assembly 32 drives the right abutment unit 41 to move, the second drive cylinder 321 in the second drive assembly 32 can be connected to the air supply line through the second throttle valve 323 to control the moving speed of the right abutment unit 41. By adjusting the second throttle valve 323, the air flow supplied to the second drive cylinder 321 is adjusted, thereby controlling the driving speed of the second drive cylinder 321 and realizing the adjustment of the moving speed of the right abutment unit 41. When the right abutment unit 41 begins to move toward the substrate group 100, the moving speed of the right abutment unit 41 can be relatively fast. When the right abutment unit 41 approaches the substrate group 100, the moving speed of the right abutment unit 41 decreases to reduce the impact force when the right abutment unit 41 contacts the substrate group 100.

[0077] In the initial state, the distance between the left abutting unit 31 and the right abutting unit 41 is greater than the width of the substrate group 100 in the left-right direction. When the substrate group 100 is placed in the substrate positioning mechanism, the left abutting unit 31 and the right abutting unit 41 are driven by the corresponding second driving components 32, and the left abutting unit 31 and the right abutting unit 41 move toward the substrate group 100, so that the distance between the left abutting member 313 of the left abutting unit 31 and the right abutting member 412 of the right abutting unit 41 gradually changes to be the same as the length of the substrate group 100 in the left-right direction. At this time, the left abutting member 313 of the left abutting unit 31 and the right abutting member 412 of the right abutting unit 41 contact the substrate group 100 to position the left and right ends of the substrate group 100. Meanwhile, the partition plate 311 on the left abutting unit 31 and the partition plate 311 on the right abutting unit 41 are located between adjacent substrates 101. When the substrate group 100 is abutted by the front abutting unit 11 and the rear abutting unit 21, the adjacent substrates 101 abut against the corresponding partition plate 311 to adjust the spacing between the adjacent substrates 101.

[0078] In other embodiments, one of the left positioning module 3 and the right positioning module 4 includes a second driving component 32, while the other does not. For example, the right abutment 412 remains in a fixed position, and the second driving component 32 drives the left abutment 313 to move toward the substrate assembly 100. At the same time, the distance between the left abutment 313 and the right abutment 412 decreases, and the distance between the left abutment 313 and the right abutment 412 gradually changes to be the same as the length of the substrate assembly 100 in the left-right direction, so as to position the left and right ends of the substrate assembly 100; or, the left abutment 313 remains in a fixed position, and the second driving component 32 drives the right abutment 412 to move toward the substrate assembly 100. At the same time, the distance between the right abutment 412 and the left abutment 313 decreases, and the distance between the right abutment 412 and the left abutment 313 gradually changes to be the same as the length of the substrate assembly 100 in the left-right direction, so as to position the left and right ends of the substrate assembly 100. When the position of the right abutment member 412 remains unchanged, the right abutment unit 41 may not be provided with a partition plate 311, or the partition plate 311 of the right abutment unit 41 may be located between adjacent substrates 101 in the initial position; when the position of the left abutment member 313 remains unchanged, the left abutment unit 31 may not be provided with a partition plate 311, or the partition plate 311 of the left abutment unit 31 may be located between adjacent substrates 101 in the initial position.

[0079] In the right positioning module 4, the second driving component 32 and the right abutment unit 41 can be respectively mounted on the second mounting plate 33, so that the second driving component 32, the right abutment unit 41 and the second mounting plate 33 form a whole. Specifically, the second driving cylinder 321 of the second driving component 32 can be fixedly mounted on the second mounting plate 33, and the right abutment unit 41 can be slidably mounted on the second mounting plate 33. When the second driving cylinder 321 drives the right abutment unit 41 to move, the right abutment unit 41 can slide relative to the second mounting plate 33. Specifically, the right mounting plate 411 of the right abutment unit 41 can be provided with a slide rail, and the second mounting plate 33 is provided with a slide groove that mates with the slide rail on the right mounting plate 411. The right abutment unit 41 and the second mounting plate 33 are slidably connected through this slide rail and slide groove.

[0080] In the right positioning module 4, the second mounting plate 33 can be mounted on the mounting frame 5 via the second column 331, so that the second drive assembly 32 and the right abutment unit 41 are indirectly mounted on the mounting frame 5. The second column 331 is supported between the second mounting plate 33 and the mounting frame 5 to control the distance between the second mounting plate 33 and the mounting frame 5. By controlling the length of the second column 331, the height of the right abutment unit 41 can be controlled to ensure that the right abutment member 412 of the right abutment unit 41 and the base plate assembly 100 are at the same height.

[0081] Mounting bracket 5 is used to install on the main structure of the coating equipment so that the front positioning module 1, rear positioning module 2, left positioning module 3 and right positioning module 4 mounted on mounting bracket 5 are installed on the main structure of the coating equipment, and the front positioning module 1, rear positioning module 2, left positioning module 3 and right positioning module 4 can be located at the same height.

[0082] When positioning the substrate 101, the front abutting unit 11, rear abutting unit 21, left abutting unit 31, and right abutting unit 41 respectively abut against the substrate group 100 to position the substrate group 100 in four directions (front, back, left, and right). Simultaneously, adjacent substrates 101 are separated by a partition plate 311 to ensure that the spacing between adjacent substrates 101 is a predetermined value, thereby completing the positioning of the substrate group 100. After the substrate group 100 is positioned, the multiple substrates 101 in the substrate group 100 can move sequentially towards the coating head for continuous coating operations. Specifically, the substrate group 100 may include two substrates 101, and the substrate positioning mechanism can position two substrates 101 at a time.

[0083] This invention also provides a coating apparatus for coating substrates 101 in a substrate assembly 100. The coating apparatus includes a coating head and the aforementioned substrate positioning mechanism. After the substrate assembly 100 is positioned by the substrate positioning mechanism, the substrates 101 in the substrate assembly 100 move sequentially toward the coating head to continuously perform coating operations.

[0084] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
