Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a coating substrate. Background Technology

[0002] Perovskite solar cells and tandem solar cells mostly employ sheet coating technology to coat the functional layers. After coating is completed, the sheets are typically removed manually or using robotic arms or forks. However, the sheets are difficult to remove once they are attached to the coating platform. Improving the efficiency of sheet removal during coating operations has become a pressing technical challenge for the industry. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a coating platform that is easy to remove after the coating operation on the coating substrate is completed.

[0004] To achieve the above objectives, this application provides a coating substrate, comprising: The base body has a coating platform on it, which is used to place the coating substrate; Both the substrate body and the coating platform are provided with multiple through holes, and the through holes on the substrate body match the through holes on the coating platform. Top rod fixing plate, the top rod fixing plate is set below the base body; The top rod fixing plate is provided with multiple top rods, which pass through the through holes on the base body and the coating platform in sequence; The lifting unit is connected to the top rod fixing plate and is used to control the protrusion size of the top rod on the surface of the coating platform.

[0005] Preferably, the lifting unit controls the protrusion size of the top rod on the coating platform surface by controlling the gap size between the top rod fixing plate and the bottom of the base body.

[0006] Preferably, the end of the push rod facing the coating platform is provided with a push pin, which is made of non-metallic material.

[0007] Preferably, the ejector pin is made of PEEK material.

[0008] Preferably, the end of the push rod facing the coating platform is provided with a chamber, and a telescopic part is provided inside the chamber; The ejector pin is connected to the telescopic part.

[0009] Preferably, the end of the chamber is provided with an end cap, through which the ejector pin passes.

[0010] Preferably, the telescopic part is a spring.

[0011] Preferably, when the spring is not compressed, the ejector pin protrudes onto the surface of the end cap.

[0012] Preferably, multiple push rods are evenly distributed on the push rod fixing plate.

[0013] Preferably, a guide tube is provided inside the through hole of the base body; The push rod penetrates the guide tube; The push rod is matched with the guide tube.

[0014] The above technical solution facilitates the placement of the coating substrate before coating begins and the removal of the coating substrate after coating is completed. The non-metallic material of the ejector pins avoids damage to the coating substrate when the ejector pins come into contact with it. The cooperation between the ejector pins and the spring ensures that each ejector pin can bear force when it rises, and that the force on each ejector pin is uniform. This avoids the phenomenon that some ejector pins do not contact the lower surface of the coating substrate when it rises, which would cause the coating substrate to be suspended in a local area and thus cause the coating substrate to shake.

[0015] Other features and advantages of this application will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing this application. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0025] Example 1 Figure 1This is a schematic diagram of the three-dimensional structure of the coating substrate according to an embodiment of this application. Figure 2 This is a side view of the coating substrate according to an embodiment of this application. Figure 3 This is a schematic diagram of the structure when the ejector pin and ejector rod are engaged according to an embodiment of this application, as shown below. Figure 1-3 As shown in the figure, the coating substrate of this application embodiment includes: substrate body 101.

[0026] The coating platform in this embodiment is used to perform coating operations on sheet material, i.e. sheet-shaped coating substrate 107.

[0027] In one exemplary embodiment, a coating platform 102 is provided on the base body 101, and the coating platform 102 is used to place the coating substrate 107.

[0028] In one exemplary embodiment, the base body 101 and the coating platform 102 may be integrally formed, as needed.

[0029] In one exemplary embodiment, the base body is made of marble, if necessary.

[0030] In one exemplary embodiment, the upper surface of the coating platform 102 is a flat surface.

[0031] In one exemplary embodiment, both the base body 101 and the coating platform 102 are provided with multiple through holes.

[0032] In one exemplary embodiment, the through holes on the base body 101 match the through holes on the coating platform 102; it can be understood that the through holes on the base body 101 correspond one-to-one with the through holes on the coating platform 102.

[0033] In one exemplary embodiment, the diameter of the through hole on the coating platform 102 is not greater than the diameter of the through hole on the base body 101 as needed. Typically, the diameter of the through hole on the coating platform 102 is smaller than the diameter of the through hole on the base body 101.

[0034] In one exemplary embodiment, the coating base of this application embodiment further includes: a top rod fixing plate 103.

[0035] In one exemplary embodiment, the top rod fixing plate 103 is disposed below the base body 101.

[0036] In one exemplary embodiment, a gap is provided between the top rod fixing plate 103 and the lower surface of the base body 101.

[0037] In one exemplary embodiment, a plurality of push rods 104 are provided on the push rod fixing plate 103.

[0038] In one exemplary embodiment, a plurality of push rods 104 are evenly distributed on the push rod fixing plate 103; the push rods 104 can be divided into multiple columns as needed, with adjacent push rods 104 in each column having the same spacing and adjacent columns having the same spacing dimension.

[0039] In one exemplary embodiment, the top rod 104 passes through the through hole on the base body 101 and the through hole on the coating platform 102 in sequence.

[0040] In one exemplary embodiment, the coating platform of this application further includes a lifting unit.

[0041] In one exemplary embodiment, the lifting unit is connected to the top rod fixing plate 103.

[0042] In one exemplary embodiment, the lifting unit is used to control the protrusion size of the top rod 104 on the upper surface of the coating platform 102.

[0043] In one exemplary embodiment, the lifting unit controls the protrusion size of the top rod 104 on the upper surface of the coating platform 102 by controlling the gap size between the top rod fixing plate 103 and the bottom of the base body 101; it can be understood that when the lifting unit controls the top rod fixing plate 103 to rise, it causes the top rod 104 to protrude on the upper surface of the coating platform 102; when the lifting unit controls the top rod fixing plate 103 to fall downward, it causes the top rod 104 to be submerged in the coating platform 102.

[0044] In one exemplary embodiment, the lifting unit can be an existing lifting mechanism. That is, how the lifting unit specifically achieves lifting control and the specific mechanism connection relationship are not the innovation of this application. The lifting unit of this application adopts the existing technical solution and is only used to drive the top rod fixing plate 103 to move synchronously in the vertical direction during lifting. For example, the lifting end of the lifting unit is a plate-shaped structure, which is attached to the bottom of the top rod fixing plate 103.

[0045] In one exemplary embodiment, the top rod 104 is provided with a pin 106 at one end facing the coating platform 102, that is, the upper end of the top rod 104 is provided with a pin 106, and the lower end of the top rod 104 is fixed on the top rod fixing plate 103.

[0046] In one exemplary embodiment, the diameter of the ejector pin 106 is not greater than the diameter of the ejector rod 104, and typically the diameter of the ejector pin 106 is smaller than the diameter of the ejector rod 104.

[0047] In one exemplary embodiment, the end of the ejector pin 106 facing the coating substrate 107 is flat as needed. This can be understood as the ejector pin 106 and the coating substrate 107 being in surface contact rather than sharp point contact when they are in contact.

[0048] In one exemplary embodiment, the ejector pin 106 is made of a non-metallic material. The non-metallic material is chosen to avoid damage to the coating substrate 107 when the ejector pin 106, which is made of metallic material, is raised.

[0049] In one exemplary embodiment, the ejector pin 106 is made of PEEK material.

[0050] In one exemplary embodiment, PEEK material is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, easy processing and high mechanical strength; PEEK, or polyether ether ketone, has corrosion resistance, aging resistance, wear resistance and strong flexibility.

[0051] In one exemplary embodiment, the top rod 104 has a cavity at one end facing the coating platform 102, that is, the upper end of the top rod 104 has a cavity, and a telescopic part 108 is provided in the cavity.

[0052] In one exemplary embodiment, the telescopic portion 108 may be a spring, if necessary.

[0053] In one exemplary embodiment, the length of the spring in its uncompressed state is not greater than the length of the chamber, as required.

[0054] In one exemplary embodiment, the ejector pin 106 is connected to the telescopic portion 108, that is, the lower end of the ejector pin 106 is connected to the upper end of the spring.

[0055] In one exemplary embodiment, the lower part of the ejector pin 106 is provided with an end as needed to increase the lower surface area of ​​the ejector pin 106 so that the spring can support the ejector pin 106.

[0056] In one exemplary embodiment, the end of the chamber is provided with an end cap 109, and the ejector pin 106 passes through the end cap 109; it can be understood that the end cap 109 is provided with a small hole, the diameter of which is larger than the diameter of the ejector pin 106 and smaller than the diameter of the spring.

[0057] In one exemplary embodiment, when the spring is not compressed, the ejector pin 106 protrudes on the surface of the end cap 109; it can be understood that when the upper part of the ejector pin 106 does not support the coating substrate 107, the ejector pin 106 protrudes on the upper surface of the end cap 109.

[0058] In one exemplary embodiment, a guide tube 105 is provided in the through hole of the base body 101 as needed, and the top rod 104 passes through the guide tube 105.

[0059] In one exemplary embodiment, the push rod 104 is matched with the guide tube 105.

[0060] In one exemplary embodiment, the guide tube 105 is used to limit the offset of the push rod 104 as the push rod 104 moves up and down with the push rod fixing plate 103.

[0061] In an exemplary embodiment, when the coating platform of this application is coating the coating substrate 107, the push rod fixing plate 103 first moves downward until the upper end of the push pin 106 no longer protrudes from the upper surface of the coating platform 102, and then the coating substrate 107 is placed on the coating platform 102. After the coating operation of the coating substrate 107 is completed, the lifting unit controls the push rod fixing plate 103 to rise, driving the push pin 106 to rise and lift the coating substrate 107, so that the lower surface of the coating substrate 107 is separated from the contact with the coating platform 102. Since there is a gap between the lower surface of the coating substrate 107 and the upper surface of the coating platform 102, the coating substrate 107 can be easily removed from the coating platform 102.

[0062] In an exemplary embodiment, when the ejector pin 106 is raised, the weight of the coating substrate 107 will exert a downward force on the ejector pin 106. Due to the cooperation between the ejector pin 106 and the spring, each ejector pin 106 can contact the coating substrate 107, that is, the force on each ejector pin 106 is uniform, thus avoiding the phenomenon of the coating substrate 107 shaking when the ejector pin 106 is raised.

[0063] In one exemplary embodiment, the coating substrate 107 in this application embodiment is, for example, glass.

[0064] In one exemplary embodiment, the movement direction of the top rod fixing plate 103 in this application embodiment is perpendicular to the upper surface of the coating platform 102.

[0065] In one exemplary embodiment, all push rods 104 and all push pins 106 in this application embodiment are of the same size.

[0066] In an exemplary embodiment, when preparing for coating operations by placing the coating substrate 107 on the coating platform 102, the ejector pin 106 can be raised first, i.e., the ejector pin 106 can be raised on the upper surface of the coating platform 102. Then, the coating substrate 107 covers all the ejector pins 106. After the coating substrate 107 is in full contact with the ejector pins 106, the ejector pins 106 lower the coating substrate 107 until it is attached to the upper surface of the coating platform 102. Because there is a gap between the coating substrate 107 and the coating platform 102, it is convenient to place the coating substrate 107 on the coating platform 102 when using grippers, forks, or manual handling.
