Description

Technical Field

[0001] The utility model relates to the technical field of crucible cleaning jigs, in particular to a line source crucible cleaning jig. Background Art

[0002] Currently, in the OLED evaporation process, the line source crucible is mainly filled with organic materials, and the organic materials are evaporated onto the glass substrate through physical deposition. The temperature and environmental control requirements are extremely high during the entire process, so the cleaning of the line source crucible is also very strict.

[0003] The existing line source crucible includes a crucible cover 1 and a crucible body 2. Figure 1 As shown, a protrusion 3 is provided on the bottom surface of the crucible cover 1. Figure 2 As shown, a groove 4 corresponding to the shape and size of the protrusion 3 is provided on the top surface of the crucible body 2, so as to prevent the crucible cover 1 from moving horizontally on the crucible body 2. A plurality of nozzles 5 are provided on the crucible cover 1. When the crucible cover 1 is cleaned by sandblasting, it is necessary to avoid the sandblasting directly spraying the nozzle 5. At the same time, when the crucible cover 1 and the crucible body 2 are installed, a plurality of through holes 6 are provided on the edges of the crucible cover 1 and the crucible body 2 to facilitate the bolts to pass through the crucible cover 1 and the crucible body 2 and connect with the nuts. Therefore, during the sandblasting process, the surfaces where the crucible cover 1 and the crucible body 2 contact each other and the through holes 6 should be avoided. Utility Model Content

[0004] The utility model aims to provide a line source crucible cleaning jig, which can protect the nozzle on the crucible cover, the bottom surface of the crucible cover and the top surface of the crucible body during sandblasting cleaning.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] A line-source crucible cleaning jig includes a crucible lid jig for covering the top surface of the crucible lid and a crucible body jig for covering the bottom surface of the crucible lid and the top surface of the crucible body. The crucible lid jig includes a nozzle slot for covering the nozzle on the crucible lid. The nozzle cover protects the nozzle during sandblasting. The crucible body jig protects both the bottom and top surfaces of the crucible lid, preventing uneven contact between the crucible body and lid from affecting the seal between the lid and the crucible body.

[0007] Furthermore, a through groove is provided in the middle of the crucible jig, which is used to allow sandblasting sand and gravel to enter the crucible through the through groove and clean the inner wall of the crucible.

[0008] Furthermore, the length of the nozzle slot is greater than the overall length of all nozzles on the crucible cover, so that all nozzles on the crucible cover can be covered by the length of the nozzle slot.

[0009] Furthermore, the nozzle slot is provided with at least one partition plate positioned on opposite sides of the nozzle, along with the end of the nozzle slot. When the nozzle slot is covering the nozzle, the partition plate's surface facing one of the nozzle slot's ends and the surface of the nozzle slot's end facing the partition plate each contact a nozzle. This partition plate serves to prevent the nozzle from being positioned while also limiting the position of the crucible cover jig on the crucible cover.

[0010] Furthermore, a chamfer is provided between the partition and the inner wall of the nozzle slot, which facilitates cleaning of the nozzle slot and prevents sand and gravel from being stuck in the gap between the nozzle slot and the partition.

[0011] Furthermore, the bottom end height of the partition is higher than the bottom end height of the crucible cover jig. Its function is to prevent the partition from lifting the crucible cover jig through the design of the partition size, thereby avoiding the formation of a gap between the crucible cover jig and the crucible cover.

[0012] Furthermore, each corner of the crucible jig is provided with a mounting hole corresponding to a through-hole at the corner of the crucible lid. This facilitates the mounting of the crucible jig to the crucible lid and the crucible body. By providing mounting holes only at the corners of the crucible jig, rather than providing mounting holes that correspond one-to-one with the through-holes along the edge of the crucible jig, the crucible jig can be secured to the crucible lid or the crucible body while the through-holes on the edge of the crucible lid or the crucible body are shielded by the crucible lid jig. The through-holes at the corners, which require bolts to pass through, also serve as shielding and protection.

[0013] Furthermore, a limiting groove having the same shape and size as the groove on the top surface of the crucible body is provided on the top surface of the crucible body, so as to prevent the crucible body jig from shifting horizontally on the bottom surface of the crucible cover through the provision of the limiting groove.

[0014] Furthermore, a limiting ring having the same shape and size as the protrusion on the bottom surface of the crucible cover is provided on the bottom surface of the crucible body to prevent the crucible body jig from translating on the top surface of the crucible body through the provision of the limiting ring.

[0015] The utility model has the beneficial effects:

[0016] 1. The nozzle cover can protect the nozzle on the crucible cover when the crucible cover is sandblasted and cleaned; the crucible body fixture can protect both the bottom surface of the crucible cover and the top surface of the crucible body, thereby preventing the contact surface between the crucible body and the crucible cover from being uneven and affecting the sealing of the crucible cover and the crucible body when they are closed;

[0017] 2. By setting the partition, the position of the crucible cover fixture on the crucible cover can be restricted while avoiding the nozzle position. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] A line source crucible cleaning fixture, such as Figure 3 、 Figure 4 As shown, the crucible lid jig 7 includes a crucible lid jig 7 for covering the top surface of the crucible lid 1 and a crucible body jig 8 for covering the bottom surface of the crucible lid 1 and the top surface of the crucible body 2. The crucible lid jig 7 includes a nozzle slot 9 for covering the nozzle 5 on the crucible lid 1. The nozzle slot 9 covers the nozzle 5, protecting the nozzle 5 on the crucible lid 1 during sandblasting. The crucible body jig 8 protects both the bottom surface of the crucible lid 1 and the top surface of the crucible body 2, preventing uneven contact between the crucible body 2 and the crucible lid 1 from affecting the seal when the crucible lid 1 and the crucible body 2 are closed.

[0029] Specifically, such as Figure 5 As shown, a through slot 15 is provided in the middle of the crucible jig 8. The function of the through slot 15 is to allow the sand and gravel used for sandblasting to pass through the through slot 15 into the crucible body 2 to clean the inner wall of the crucible body 2.

[0030] Specifically, such as Figure 3 As shown, the length of the nozzle slot 9 is greater than the overall length of all nozzles 5 on the crucible cover 1. Its function is to cover all nozzles 5 on the crucible cover 1 through the design of the length of the nozzle slot 9.

[0031] Specifically, such as Figure 3 As shown, the nozzle slot 9 is provided with at least one partition 10 for positioning itself on opposite sides of the nozzle 5 with the end of the nozzle slot 9. When the nozzle slot 9 covers the nozzle 5, the partition 10 contacts one nozzle 5 on one side of the nozzle slot 9 facing one end, and on the side of the nozzle slot 9 facing the partition 10. The partition 10 serves to prevent the nozzle 5 from being positioned while limiting the position of the crucible lid jig 7 on the crucible lid 1.

[0032] Specifically, such as Figure 3As shown, a chamfer 11 is provided between the baffle 10 and the inner wall of the nozzle slot 9. The chamfer 11 facilitates cleaning of the nozzle slot 9 and prevents sand and gravel from being stuck in the gap between the nozzle slot 9 and the baffle 10.

[0033] Specifically, such as Figure 3 As shown, the bottom end height of the partition 10 is higher than the bottom end height of the crucible cover jig 7. Its function is to prevent the partition 10 from lifting the crucible cover jig 7 through the design of the size of the partition 10, thereby avoiding the formation of a gap between the crucible cover jig 7 and the crucible cover 1.

[0034] Specifically, such as Figure 4 As shown, each corner of the crucible jig 8 is provided with a mounting hole 12 corresponding to the through hole 6 at the corner position of the crucible cover 1. The purpose of the mounting hole 12 is to facilitate the installation of the crucible jig 8 to the crucible cover 1 and to facilitate the installation of the crucible jig 8 to the crucible body 2.

[0035] Specifically, such as Figure 4 As shown, a limiting groove 13 having the same shape and size as the groove 4 on the top surface of the crucible body 2 is provided on the top surface of the crucible body jig 8. Its function is to prevent the crucible body jig 8 from shifting horizontally on the bottom surface of the crucible cover 1 through the setting of the limiting groove 13.

[0036] Specifically, such as Figure 5 As shown, a limiting ring 14 having the same shape and size as the protrusion 3 on the bottom surface of the crucible cover 1 is provided on the bottom surface of the crucible body 2. The limiting ring 14 can prevent the crucible body fixture 8 from translating on the top surface of the crucible body 2.

[0037] The working principle of this embodiment is described as follows: when the crucible cover 1 needs to be sandblasted, the nozzle slots 9 of the crucible cover jig 7 are aligned with the nozzles 5 and covered on the crucible cover 1, so that all the nozzles 5 are located in the nozzle slots 9. The crucible body jig 8 is installed on the bottom of the crucible cover 1. After the bolts are passed through the through holes 6 on the crucible cover 1 and the mounting holes 12 on the crucible body jig 8, the bolts are connected with nuts and the sandblasting cleaning can be carried out.

[0038] When the crucible body 2 needs to be sandblasted, the crucible body jig 8 is installed on the top of the crucible body 2, and bolts are passed through the through holes 6 on the crucible body 2 and the mounting holes 12 on the crucible body jig 8. After connecting the bolts with nuts, sandblasting can be performed.

[0039] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Based on the technical essence of the present invention and within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement of the above embodiment shall still fall within the scope of protection of the technical solution of the present invention.
