Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of OLED evaporation, and particularly to a point source crucible taking and placing device. BACKGROUND

[0002] With the progress of technology, the mainstream technology of the display industry has gradually developed from the early LCD to OLED, even Micro LED, QLED and the like, and various technologies play different roles in the market. Among them, the OLED display panel has the advantages of thin thickness, low power consumption, bendable and flexible display, and the like, and has become the development trend of the next generation of panel displays in recent years.

[0003] At present, the most commonly used method for mass production of OLED devices is evaporation. Organic materials are sublimated or vaporized by heating, and finally condense and deposit on a glass substrate to form a functional film layer. Different functional film layers are matched to emit colors visible to the naked eye under the driving of current. The current cathode metal layer is generally evaporated by a point source crucible. The point source crucible is the most frequently disassembled component during the maintenance, addition or replacement of materials.

[0004] As shown in Figure 1 and Figure 2 , the existing evaporation source device includes a circular shell 200 and an upper cover 208. The shell 200 is provided with a cavity for accommodating a crucible. A crucible placing seat 206 is arranged on the bottom wall of the cavity. In use, the crucible 100 is placed on the crucible placing seat 206. The inner wall of the shell is connected with a side upper heating wire 201 and a side lower heating wire 204 through a heating wire fixing ring 203. The crucible 100 is heated by the side upper heating wire 201 and the side lower heating wire 204. A reflecting plate 205 is further arranged on the inner wall of the cavity to play a heat preservation role. An upper cover positioning annular groove 207 is further arranged on the top surface of the shell. The bottom of the upper cover 208 is provided with a protrusion. When the upper cover is installed on the top of the shell, the protrusion is sleeved into the upper cover positioning annular groove 207. An inner baffle 202 is arranged between the side lower heating wire and the crucible. The upper edge of the inner baffle 202 is higher than the upper edge of the side lower heating wire 204 and lower than the lower edge of the side upper heating wire 201.

[0005] In order to ensure the heating effect, the structure of the crucible body 100, the side upper heating wire 201, the side lower heating wire 204, the inner baffle 202 and the heating wire fixing ring 203 is very compact. Since the height of the inner baffle 202 is limited by the heating effect, it is only a little higher than the height of the side lower heating wire 204. The inner baffle 202 cannot shield the side upper heating wire 201, resulting in that the side upper heating wire 201 and the heating wire fixing ring 203 are completely exposed.

[0006] When the personnel take and place the crucible, if wanting to take out or place the crucible quickly, and easy to cause the collision of the crucible and the heating wire fixing ring and the side part of the heating wire exposed outside, the side part of the heating wire is usually the brittle material, after the collision, the side part of the heating wire is easy to be damaged, causing the equipment to be down and to be repaired.If the personnel take out or place slowly, the material is exposed in the atmosphere for a long time, causing the material to be polluted, causing unnecessary economic loss. SUMMARY

DETAILED DESCRIPTION

[0031] Please refer to Figures 1 to 10 The application provides a point source crucible taking and placing device, which is detachably connected with a shell 200 of an evaporation source device, and comprises a top cover 306. The bottom of the top cover 306 is connected with an inner guide tube 303 for separating the side upper heating wire 201 of the evaporation source device and the crucible body 100. The length of the inner guide tube 303 extends to the inner baffle 202 of the evaporation source device, so that the side upper heating wire 201 of the evaporation source device is isolated from the crucible body 100 by the inner guide tube 303. The top cover 306 is provided with a taking and placing hole 307 for the crucible body 100 to enter and exit the chamber. The diameter of the taking and placing hole 307 is greater than the outer diameter of the crucible body and less than the inner diameter of the heating wire fixing ring 203, so that the taking and placing device does not affect the taking and placing operation of the crucible body by hand. The axis of the inner guide tube 303 coincides with the axis of the taking and placing hole 307. When the crucible body is taken out of the evaporation source device, the upper cover is detached from the shell, and the taking and placing device is installed on the shell. The side upper heating wire is isolated by the inner guide tube. During the taking and placing process, only the outer wall of the crucible body collides with the inner wall of the inner guide tube, so that the safety of the heating wire fixing ring 203 and the side upper heating wire 201 of the evaporation source device during the taking and placing process of the crucible body is improved.

[0032] Specifically, the inner diameter of the inner guide tube 303 is equal to the diameter of the taking and placing hole 307.

[0033] Specifically, the top cover 306 is a circular structure.

[0034] Specifically, the bottom of the top cover 306 is provided with an outer guide tube 305. The inner diameter of the outer guide tube 305 matches the outer diameter of the shell 200. When the taking and placing device is installed on the shell, the outer guide tube 305 is sleeved on the outer wall of the shell 200. The axis of the outer guide tube 305 coincides with the axis of the inner guide tube 303, and the length of the outer guide tube 305 is greater than the length of the inner guide tube 303. When the taking and placing device is installed, the outer guide tube 305 first contacts the outer surface of the shell, which plays a guiding role during the installation of the taking and placing device, and avoids the contact between the inner guide tube 303 and the heating wire fixing ring and the side upper heating wire during the installation process, thereby preventing the damage of the side upper heating wire.

[0035] Specifically, the bottom of the top cover 306 is provided with a positioning boss 304, the outer diameter of the positioning boss 304 matches the inner diameter of the upper cover positioning annular groove of the shell 200, when the taking and placing device is installed on the shell, the positioning boss 304 is sleeved in the upper cover positioning annular groove 207 of the shell 200. After the top cover 306 is covered on the shell, the positioning boss 304 is inserted into the upper cover positioning annular groove 207, and the function of accurately positioning the taking and placing device is achieved.

[0036] Specifically, the top of the top cover 306 is provided with a plurality of through holes 301, and the screws pass through the through holes 301 and are screw-connected with the shell 200. The top cover 306 is fixed on the shell through the screws.

[0037] Specifically, the top of the top cover 306 is provided with a grabbing ring 302. The grabbing ring 302 is arranged to facilitate personnel to grab the taking and placing device.

[0038] When the taking and placing device of the application is used, the upper cover is first removed from the shell, and then the taking and placing device is installed on the outer side of the shell. When installing, the outer guide pipe 305 first contacts the outer surface of the shell, and plays a guiding role in the installation process of the taking and placing device, avoiding the contact between the inner guide pipe 303 and the heating wire fixing ring and the side upper heating wire during the installation process, which causes damage to the side upper heating wire. When the bottom of the top cover contacts the top of the shell, the positioning boss 304 is inserted into the upper cover positioning annular groove 207, and the function of accurately positioning the taking and placing device is achieved. Then, the taking and placing device is fixed on the shell through the screws.

[0039] After the taking and placing device is installed, the lower end surface of the inner guide pipe is below the upper end surface of the inner baffle of the evaporation source device, so that the side upper heating wire of the evaporation source device and the crucible body 100 are completely separated by the inner guide pipe. Therefore, when the crucible body is taken out of the chamber of the shell or placed into the chamber, only the outer wall of the crucible body will rub against the inner wall of the inner guide pipe, and the crucible body will not collide with the side upper heating wire.

[0040] Therefore, the operator can no longer carefully take out or place the crucible body in the prior art, and the replacement efficiency can be improved. At the same time, material waste caused by long-term exposure to the atmosphere is also avoided. At the same time, the heating wire fixing ring and the side upper heating wire are also protected, and the production cost is reduced.

[0041] The application can solve the problem that the heating wire and the heating wire fixing ring on the side are damaged due to collision caused by personnel operation when the point source crucible is added or replaced or is regularly maintained, avoid unnecessary downtime and unnecessary cost budget, improve work efficiency, avoid the problem that the material is polluted or the cavity atmosphere is poor due to long-time opening of the cavity, affect the device effect, reduce the production time and material cost, and improve the product effect.

[0042] Although the specific embodiments of the application are described above, those skilled in the art should understand that the specific embodiments described are only illustrative, and are not used to limit the scope of the application, and equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the application should be covered within the scope of the claims of the application.
