Description

Technical Field

[0001] This application relates to the field of coating equipment technology, and in particular to a coating head flipping structure and coating equipment. Background Technology

[0002] Titanium oxide organometal halide semiconductors are a new type of solar cell material. They have been widely studied due to their excellent properties, such as high light absorption intensity, tunable band gap, long carrier diffusion, and strong carrier mobility.

[0003] Currently, large-size (2.4m x 1.2m) perovskite coating machines are widely used in the production and processing of perovskite solar cells. Due to the relatively long and heavy coating head in large-size perovskite coating machines, it is difficult to rotate and move the coating head when it needs to be installed or disassembled, which brings great inconvenience to the maintenance and operation of the equipment. Utility Model Content

[0004] Therefore, it is necessary to provide a coating head flipping structure and coating equipment to address the above problems.

[0005] A coating head flipping structure for a coating device, comprising:

[0006] Mounting base, which is fitted onto the welding frame of the coating equipment;

[0007] A flipping assembly includes a flipping component and a limiting component. The flipping component is engaged with the coating head of the coating equipment and rotatably mounted on the mounting base. The limiting component protrudes from the flipping component. The flipping component is configured to be controllably rotated relative to the mounting base about the axis of the coating head, thereby driving the coating head and the limiting component to rotate synchronously.

[0008] The mounting base has a protruding mating part; when the flipping component is controlled to rotate relative to the mounting base to a preset angle around the axis of the coating head, the limiting part abuts against the mating part for limiting.

[0009] In one embodiment, of the opposing first and second sides of the flipping member, the first side is engaged with the coating head of the coating equipment, and the second side is rotatably engaged with the mounting base; the limiting member protrudes from the first side; the mounting base has the mating member protruding from its surface near the flipping member.

[0010] When the flipping component is fitted onto the mounting base, the mating component is misaligned with the flipping component; and the protruding end of the mating component is bent toward the flipping component to form a mating portion, and the mating portion is at least partially located on the moving path of the limiting portion in the direction of rotation about the axis of the coating head.

[0011] In one embodiment, the limiting member includes two limiting parts, both of which protrude from the first side surface and are spaced apart in the direction of rotation around the axis of the coating head.

[0012] Wherein, at least part of the mating part is located between the two limiting parts in the direction of rotation about the axis of the coating head; when the flipping assembly is controlled to rotate about the axis of the coating head relative to the mounting base in the forward direction to a first preset angle A, one of the two limiting parts is limited to abutting the mating part; when the flipping assembly is controlled to rotate about the axis of the coating head relative to the mounting base in the reverse direction to a second preset angle B, the other of the two limiting parts is limited to abutting the mating part.

[0013] In one embodiment, the value of the first preset angle A is equal to the value of the second preset angle B, and A=B=180°.

[0014] In one embodiment, a mounting hole is formed through a recess on the first side for the coating head to pass through.

[0015] In one embodiment, the flipping assembly further includes a grip that protrudes from the second side.

[0016] In one embodiment, the mounting base includes a base body and a rotating assembly. The base body is fitted onto the welding frame of the coating equipment, the mounting end of the rotating assembly is fitted onto the base body, and the rotating end of the rotating assembly is fitted onto the flipping component.

[0017] In one embodiment, the rotating assembly includes a connecting rod, a bearing, and a roller, wherein the bearing is sleeved on the connecting rod, and the roller is rotatably sleeved on the outer periphery of the bearing;

[0018] The rotating assembly includes two sets, and the two sets of rotating assemblies are spaced apart and coupled to the base. The flipping member is rotatably placed on the shaft rollers of the two sets of rotating assemblies.

[0019] In one embodiment, the mating member protrudes from the side of the seat body near the flipping member, and the mating member, the mating portion, and the seat body enclose a limiting space, with the flipping member at least partially located within the limiting space.

[0020] A coating apparatus includes a coating head flipping structure as described in the foregoing embodiments.

[0021] The aforementioned coating head flipping structure and coating equipment include a mounting base and a flipping assembly. The mounting base is fitted onto the welding frame of the coating equipment; the flipping assembly includes a flipping component and a limiting component. The flipping component is fitted onto the coating head of the coating equipment and rotatably fitted onto the mounting base; the limiting component protrudes from the flipping component; the flipping component is configured to be controllably rotated relative to the mounting base around the axis of the coating head, thereby driving the coating head and the limiting component to rotate synchronously. A mating component protrudes from the mounting base; when the flipping assembly is controlled to rotate relative to the mounting base around the axis of the coating head to a preset angle, both the limiting component and the mating component abut against the limiting component.

[0022] Understandably, in the actual operation of the coating equipment, it is necessary to first assemble the coating head flipping structure with the welding frame and coating head of the coating equipment. Specifically, first, the mounting base is connected to the welding frame of the coating equipment, then the flipping component is rotated and connected to the mounting base, and finally, the corresponding connection between the coating head and the flipping component of the coating equipment is completed by using lifting fixtures.

[0023] Subsequently, when it is necessary to flip the coating head, the flipping component is controlled to rotate relative to the mounting base around the axis of the coating head, so that the flipping component drives the coating head and the limiting component to rotate synchronously. When the flipping component rotates to a preset angle, the limiting component can abut against the mating part on the mounting base to achieve precise flipping and positioning of the coating head, and can avoid the deviation that may occur when manually flipping the coating head, thereby effectively coating and improving the convenience and safety of equipment operation.

[0024] In other words, this application adds a coating head flipping structure between the welding frame and the coating head of the coating equipment. The flipping component drives the coating head and the limiting component to rotate synchronously. With the abutment and limiting effect of the limiting component and the mating component on the mounting base, the flipping and positioning action of the coating head can be accurately completed. Moreover, the coating head flipping structure is simple in structure and easy to operate. It eliminates the cumbersome process of flipping the coating head using large equipment such as lifting fixtures required in traditional coating equipment. It also effectively reduces the cost of equipment maintenance and operation and improves the user experience of the coating equipment. Attached Figure Description

[0036] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] Titanium oxide organometal halide semiconductors are a new type of solar cell material. They have been widely studied due to their excellent properties, such as high light absorption intensity, tunable band gap, long carrier diffusion, and strong carrier mobility.

[0041] Currently, large-size (2.4m x 1.2m) perovskite coating machines are widely used in the production and processing of perovskite solar cells. Due to the relatively long and heavy coating head in large-size perovskite coating machines, it is difficult to rotate and move the coating head when it needs to be installed or disassembled, which brings great inconvenience to the maintenance and operation of the equipment.

[0042] Therefore, to resolve the above issues, please refer to [link / reference needed]. Figures 1 to 4This application provides a coating device 200 in one or more embodiments. The coating device 200 includes a coating head flipping structure 100. The coating head flipping structure 100 uses a flipping member 111 to drive the coating head 21 and the limiting member 114 to rotate synchronously. Then, through the abutment and limiting of the limiting member 114 and the mating member 101, the coating head 21 can be accurately positioned during the flipping process.

[0043] Specifically, please see Figures 1 to 4 The coating head flipping structure 100 includes a mounting base 10 and a flipping assembly 11. The mounting base 10 is fitted onto the welding frame 20 of the coating equipment 200; the flipping assembly 11 includes a flipping member 111 and a limiting member 114. The flipping member 111 is fitted onto the coating head 21 of the coating equipment 200 and rotatably fitted onto the mounting base 10; the limiting member 114 protrudes from the flipping member 111; the flipping member 111 is configured to be controllably rotated relative to the mounting base 10 about the axis of the coating head 21, and to drive the coating head 21 and the limiting member 114 to rotate synchronously. A mating member 101 protrudes from the mounting base 10; when the flipping assembly 11 is controlled to rotate relative to the mounting base 10 about the axis of the coating head 21 to a preset angle, the limiting member 114 and the mating member 101 abut and limit the rotation.

[0044] Understandably, during the actual operation of the coating equipment 200, the assembly of the coating head flipping structure 100 with the welding frame 20 and coating head 21 of the coating equipment 200 needs to be completed first. Specifically, the mounting base 10 is first connected to the welding frame 20 of the coating equipment 200, then the flipping component 111 is rotated and connected to the mounting base 10, and finally the corresponding connection between the coating head 21 and the flipping component 111 of the coating equipment 200 is completed by using a lifting fixture.

[0045] Subsequently, when it is necessary to flip the coating head 21, the flipping component 111 is controlled to rotate relative to the mounting base 10 around the axis of the coating head 21, so that the flipping component 111 drives the coating head 21 and the limiting component 114 to rotate synchronously; and when the flipping component 111 rotates to a preset angle, the limiting component 114 can abut against the mating component 101 on the mounting base 10 to achieve precise flipping and positioning of the coating head 21, and can avoid the deviation that may occur when manually flipping the coating head 21, thereby effectively coating and improving the convenience and safety of equipment operation.

[0046] In other words, this application adds a coating head flipping structure 100 between the welding frame 20 and the coating head 21 of the coating equipment 200. The flipping component 111 drives the coating head 21 and the limiting component 114 to rotate synchronously. With the abutment and limiting effect of the limiting component 114 and the mating component 101 on the mounting base 10, the flipping and positioning action of the coating head 21 can be accurately completed. Moreover, the coating head flipping structure 100 has a simple structure and is easy to operate. It eliminates the cumbersome process of flipping the coating head 21 using large equipment such as lifting fixtures required by the traditional coating equipment 200. It also effectively reduces the cost of equipment maintenance and operation and improves the user experience of the coating equipment 200.

[0047] In some embodiments, see Figure 2 and Figure 3 Of the first and second opposing sides of the flipper 111, the first side mates with the coating head 21 of the coating equipment 200, and the second side is rotatably mated to the mounting base 10. A limiting member 114 protrudes from the first side. A mating member 101 protrudes from the surface of the mounting base 10 near the flipper 111. When the flipper 111 is mated to the mounting base 10, the mating member 101 is misaligned with the flipper 111; and the protruding end of the mating member 101 is bent toward the flipper 111 to form a mating portion 102. The mating portion 102 is at least partially located on the moving path of the limiting portion 115 in the direction of rotation about the axis of the coating head 21.

[0048] It is understandable that during the controlled rotation of the flipping member 111, the coating head 21 and the limiting member 114 rotate synchronously around the axis, since at least part of the mating part 102 is disposed on the moving path of the limiting part 115, the limiting member 114 will gradually approach the mating member 101; and when the flipping member 111 rotates to the preset angle, the limiting member 114 will abut against the mating part 102 to limit the further rotation of the flipping member 111, thereby achieving precise positioning of the coating head 21 at the preset angle.

[0049] In some embodiments, see Figure 3 and Figure 4 The limiting member 114 includes two limiting portions 115, both of which protrude from the first side surface and are spaced apart in the direction of rotation about the axis of the coating head 21. The mating portion 102 is at least partially located between the two limiting portions 115 in the direction of rotation about the axis of the coating head 21. When the flipping assembly 11 is controlled to rotate in the forward direction relative to the mounting base 10 about the axis of the coating head 21 to a first preset angle A, one of the two limiting portions 115 is limited and abuts against the mating portion 102. When the flipping assembly 11 is controlled to rotate in the reverse direction relative to the mounting base 10 about the axis of the coating head 21 to a second preset angle B, the other of the two limiting portions 115 is limited and abuts against the mating portion 102.

[0050] It is understood that, in the direction of rotation around the axis of the coating head 21, two limiting parts 115 are spaced apart on the first side of the flipping member 111, and the mating part 102 is located between the two limiting parts 115; then the opposite ends of the mating part 102 are respectively close to one of the two limiting parts 115.

[0051] Specifically, for ease of understanding, the two opposite ends of the mating part 102 are defined as the first end and the second end, respectively, and the two limiting parts 115 are defined as the first limiting part 115 and the second limiting part 115, respectively. The first end is closer to the first limiting part 115, and the second end is closer to the second limiting part 115. There is a first gap distance between the first end and the first limiting part 115, and a second gap distance between the second end and the second limiting part 115. It is also defined that the direction of rotation from the first limiting part 115 to the second limiting part 115 around the axis of the coating head 21 is positive, and the direction of rotation from the second limiting part 115 to the first limiting part 115 around the axis of the coating head 21 is negative.

[0052] Thus, when the flipping assembly 11 rotates forward, the second limiting part 115 abuts against the second end of the mating part 102 after rotating to the first preset angle A, and the distance moved by the second limiting part 115 by rotating the preset angle A is equal to the second interval distance. Correspondingly, when the flipping assembly 11 rotates in the reverse direction, the first limiting part 115 abuts against the first end of the mating part 102 after rotating to the second preset angle B, and the distance moved by the first limiting part 115 by rotating the preset angle B is equal to the first interval distance.

[0053] Because the first interval distance has three possibilities: greater than, less than, or equal to the second interval distance. Specifically, when the first interval distance is greater than the second interval distance, the preset angle A is greater than the second preset angle B; when the first interval distance is equal to the second interval distance, the preset angle A is equal to the second preset angle B; and when the first interval distance is less than the second interval distance, the preset angle A is less than the second preset angle B.

[0054] In other words, by setting two limiting parts 115, this application can achieve precise positioning of the coating head 21 at different preset angles when rotating in the forward and reverse directions, thereby meeting the flipping requirements of the coating equipment 200 in different operating scenarios and improving the flexibility and adaptability of the coating head 21 flipping.

[0055] In some embodiments, see Figure 3 and Figure 4 The value of the first preset angle A is equal to the value of the second preset angle B, and A=B=180°.

[0056] Understandably, during the actual operation of the coating equipment 200, the working end of the coating head 21 needs to be placed vertically downward along the direction of gravity. When it is necessary to repair or replace the working end of the coating head 21, the coating head 21 needs to be flipped so that its working end faces upward, so that the working end of the coating head 21 avoids other parts of the coating equipment 200, making maintenance and replacement operations convenient.

[0057] Therefore, this application sets both the first preset angle A and the second preset angle B to 180°, enabling the coating head 21 to achieve precise 180° rotation and positioning during both forward and reverse rotations through the precise contact between the limiting part 115 and the mating part 102. This ensures that the coating head 21 rotates 180° forward from its initial position vertically downward along the direction of gravity to the opposite position, and then rotates 180° backward from the opposite position back to its initial position. The opposite position allows the working end of the coating head 21 to avoid obstructing other components of the coating equipment 200 and is fully exposed, greatly facilitating operation of the working end of the coating head 21 by maintenance personnel.

[0058] In some embodiments, see Figure 3 and Figure 4 A mounting hole 112 is formed through a recess on the first side, which is used for the coating head 21 to pass through.

[0059] Understandably, the size and shape of the mounting hole 112 need to match the outer diameter of the coating head 21 so that the coating head 21 can be tightly inserted therein, effectively preventing the coating head 21 from shaking or shifting during the flipping process and providing a stable mounting base for the coating head 21.

[0060] In some embodiments, see Figure 3 and Figure 4 The flipping assembly 11 also includes a grip 113, which protrudes from the second side.

[0061] Understandably, when it is necessary to flip the coating head 21, the operator can directly hold the grip 113 and apply an appropriate torque to drive the flipper 111 to rotate around the axis of the coating head 21. The grip 113 facilitates manual control of the flipper 111 by the operator and allows the operator to more precisely control the flipping speed.

[0062] In some embodiments, see Figure 3 and Figure 4 The flipping assembly 11 also includes a mounting member 116, which is connected between the flipping assembly 111 and the coating head 21.

[0063] In some embodiments, see Figure 1 and Figure 2The mounting base 10 includes a base body 103 and a rotating assembly 104. The base body 103 is fitted onto the welding frame 20 of the coating equipment 200. The mounting end of the rotating assembly 104 is fitted onto the base body 103, and the rotating end of the rotating assembly 104 is fitted onto the flipping component 111.

[0064] Specifically, the rotating assembly 104 includes a connecting rod 1041, a bearing 1042, and a roller 1043. The bearing 1042 is sleeved on the connecting rod 1041, and the roller 1043 is rotatably sleeved on the outer periphery of the bearing 1042. The rotating assembly 104 includes two sets, and the two sets of rotating assemblies 104 are spaced apart and connected to the base 103. The flipping member 111 is rotatably placed on the roller 1043 of the two sets of rotating assemblies 104.

[0065] It is understandable that by setting two sets of rotating components 104 and rotatably placing the flipping component 111 on the rollers 1043 of the two sets of rotating components 104, the rolling characteristics of the rollers 1043 can be used to reduce the frictional resistance of the flipping component 111 during rotation, making the flipping component 111 rotate more smoothly and steadily.

[0066] In some embodiments, see Figure 1 and Figure 2 The mating part 101 protrudes from the side of the seat 103 near the flipping part 111. The mating part 101, the mating part 102 and the seat 103 enclose a limiting space 105, and the flipping part 111 is at least partially located within the limiting space 105.

[0067] Understandably, the limiting space 105 formed by the mating part 101, the mating portion 102, and the seat 103 can effectively limit the rotation range of the flipping part 111. During the rotation of the flipping part 111, the limiting space 105 can provide a clear movement boundary for the flipping part 111, preventing the flipping part 111 from colliding or interfering with other components due to excessive rotation, which helps to ensure the accuracy and safety of the coating head 21 flipping action.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
