Description

Technical Field

[0001] This utility model belongs to the field of coating machine technology, specifically relating to a double gantry coating motion module and a coating machine. Background Technology

[0002] In slot coating equipment used to manufacture solar cells, different thin films need to be formed on the surface of the cell substrate to achieve specific functions. At this time, a coating machine is needed to coat the surface of the cell substrate and then crystallize the cell substrate to form a surface thin film. Existing coating machines usually consist of a coating platform and a gantry. The cell substrate is placed on the coating platform, the gantry sprays out the coating solution, and the blade is cleaned after coating is completed.

[0003] However, if the existing double gantry coating machine adopts a design where the gantry moves but the platform remains stationary, the movement of the gantry may cause disturbance to the coating liquid due to mechanical vibration, thereby increasing the risk of bubble formation and affecting the coating uniformity. On the other hand, if the design adopts a design where the platform moves but the gantry remains stationary, the presence of the cleaning tank will make the disassembly and assembly of the coating blades of the double gantry coating machine very inconvenient.

[0004] Therefore, overcoming the limitation of double-gantry coating machines in not being able to simultaneously handle the disassembly, assembly, and cleaning of coating blades is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0006] This disclosure provides at least one dual-gantry coating motion module and a coating machine.

[0007] In a first aspect, embodiments of this disclosure provide a double-gantry coating motion module, comprising: a fixed gantry with a common track on one side and a first independent track and a second independent track arranged in parallel on the other side; a first cleaning component that slides between the common track and the first independent track; a second cleaning component that slides between the common track and the second independent track; and a first coating blade and a second coating blade that are mounted on the fixed gantry and move along the Z-axis.

[0008] In one alternative embodiment, the first cleaning component slides parallel to its set track to enable the first coating blade to perform soaking and cleaning operations; the second cleaning component slides parallel to its set track to enable the second coating blade to perform soaking and cleaning operations.

[0009] In one optional implementation, the ratio of the length of the first independent track to the length of the shared track is not less than 2 / 3; the ratio of the length of the second independent track to the length of the shared track is not less than 2 / 3.

[0010] In one alternative embodiment, the end of the first independent track away from the fixed gantry has the same length as the common track, and the length of the end near the fixed gantry is suitable for the first cleaning component to slide as a whole to that side; the end of the second independent track away from the fixed gantry has the same length as the common track, and the length of the end near the fixed gantry is suitable for the second cleaning component to slide as a whole to that side.

[0011] In one alternative implementation, the first cleaning component and the second cleaning component are driven independently by motor leadscrews.

[0012] In one optional embodiment, the system further includes: a first separate motion platform and a second separate motion platform; the first separate motion platform is disposed on one side of the first cleaning component and carries the coating blade to disassemble the coating blade head when both the first cleaning component and the second cleaning component slide to the other side of the fixed gantry; the second separate motion platform is disposed on one side of the second cleaning component and carries the coating blade to disassemble the coating blade head when both the first cleaning component and the second cleaning component slide to the other side of the fixed gantry.

[0013] Secondly, embodiments of this disclosure also provide a coating machine, including the dual-gantry coating motion module as described above.

[0014] The beneficial effects of this utility model are that, during the cleaning and disassembly of the coating blades, the gantry does not move and therefore no air bubbles are generated, which would affect the uniformity of the coating. At the same time, when loading and unloading the coating blade head, the cleaning component can be slid to the other side by the motion module, and can be easily assembled with the separately moving platform. In addition, the separately moving platform can be kept away from the cleaning tank and gantry during the cleaning process, avoiding waste liquid splashing onto the platform and causing pollution.

The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and drawings.

[0025] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] This disclosure provides a dual-gantry coating motion module, comprising: a fixed gantry 1, with a common track 2 on one side and a first independent track 31 and a second independent track 32 arranged side-by-side on the other side; a first cleaning component 51, which slides between the common track 2 and the first independent track 31; a second cleaning component 52, which slides between the common track 2 and the second independent track 32; and a first coating blade 41 and a second coating blade 42, which are mounted on the fixed gantry 1 and move along the Z-axis. The Z-axis direction refers to the direction in which the first coating blade 41 and the second coating blade 42 move vertically up and down along the fixed gantry 1.

[0027] In some embodiments, specifically, the first cleaning component 51 slides parallel to its set track to enable the first coating blade 41 to perform soaking and cleaning operations; the second cleaning component 52 slides parallel to its set track to enable the second coating blade 42 to perform soaking and cleaning operations.

[0028] In some embodiments, specifically, the ratio of the length of the first independent track 31 to the length of the common track 2 is not less than 2 / 3; the ratio of the length of the second independent track 32 to the length of the common track 2 is not less than 2 / 3.

[0029] In some embodiments, specifically, the end of the first independent track 31 away from the fixed gantry 1 has the same length as the common track 2, and the length of the end near the fixed gantry 1 is suitable for the first cleaning component 51 to slide as a whole to that side; the end of the second independent track 32 away from the fixed gantry 1 has the same length as the common track 2, and the length of the end near the fixed gantry 1 is suitable for the second cleaning component 52 to slide as a whole to that side.

[0030] In some embodiments, specifically, the first cleaning component and the second cleaning component are driven independently by motor leadscrews.

[0031] In some embodiments, specifically, there is a first separate motion platform 61 and a second separate motion platform 62; the first separate motion platform 61 is disposed on one side of the first cleaning component, and carries the coating blade for disassembly of the coating blade head when both the first cleaning component 51 and the second cleaning component 52 slide to the other side of the fixed gantry 1; the second separate motion platform 62 is disposed on one side of the second cleaning component 52, and carries the coating blade for disassembly of the coating blade head when both the first cleaning component 51 and the second cleaning component 52 slide to the other side of the fixed gantry 1.

[0032] Please see Figure 1 ,like Figure 1As shown, in this state, the first cleaning component 51 and the second cleaning component 52 slide directly below the first coating blade 41 and the second coating blade 42, respectively, and then move the first coating blade 41 and the second coating blade 42 in the Z-axis direction to perform a blistering operation.

[0033] Please see Figure 2 ,like Figure 2 As shown, in this state, the first cleaning component 51 and the second cleaning component 52 slide directly below the first coating blade 41 and the second coating blade 42, respectively, and then move the first coating blade 41 and the second coating blade 42 in the Z-axis direction to perform cleaning operations.

[0034] Please see Figure 3 ,like Figure 3 As shown, in this state, both the first cleaning component 51 and the second cleaning component 52 slide to the right side of the fixed gantry 1, exposing the first coating blade 41. Then, the first separate motion platform 61 moves to the blade removal position, slowly loosens the connecting bolts between the coating blade and the gantry beam, and the gantry Z-axis slowly rises, exiting the removal position. The first separate motion platform 61 moves the first coating blade 41 to the removal position, where the blade is manually removed, completing the removal of the coating blade head.

[0035] Please see Figure 4 ,like Figure 4 As shown, in this state, both the first cleaning component 51 and the second cleaning component 52 slide to the left side of the fixed gantry 1, exposing the second coating blade 42. Then, the second separate motion platform 62 moves to the blade removal position, slowly loosens the connecting bolts between the coating blade and the gantry beam, and the gantry Z-axis slowly rises and exits the removal position. The second separate motion platform 62 moves the second coating blade 42 to the removal position, where the blade is manually removed, completing the removal of the coating blade head.

[0036] Please see Figure 5 ,like Figure 5 As shown, in a second aspect, embodiments of this disclosure also provide a coating machine, including the aforementioned double-gantry coating motion module, wherein the double-gantry coating motion module is disposed below the first coating blade 41 and the second coating blade 42, according to... Figures 1 to 4 The position shown is relative to the coating blade installed on the fixed gantry 1, which allows for convenient soaking, cleaning and disassembly of the coating blade.

[0037] In summary, during the cleaning and disassembly of the coating blades, the gantry remains stationary, preventing air bubbles from affecting the uniformity of the coating. Furthermore, when loading and unloading the coating blades, the cleaning assembly can be slid to the other side via the motion module for easy assembly with the separately moving platform. Additionally, the separately moving platform can be kept away from the cleaning tank and gantry during the cleaning process, preventing waste liquid from splashing onto the platform and causing contamination.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
