Description

Technical Field

[0001] The utility model relates to the technical field of OLED production, in particular to a disassembly and assembly jig for a line source crucible cover cleaning nozzle. Background Art

[0002] The line source crucible cover is the main container for the organic material evaporation element on the OLED production line. The nozzle and the crucible cover of the line source crucible are assembled into a whole by tightening the threads. The advantage of this structure is that if the nozzle is damaged, it can be easily replaced separately without causing the entire crucible cover to be scrapped; but the disadvantage is that the threads where the nozzle and the crucible cover are combined are easily penetrated by organic materials during use on the machine. If they cannot be cleaned thoroughly during cleaning, it may easily cause machine abnormalities. In this case, the nozzle can only be disassembled for cleaning to ensure that it is clean and meet the requirements for use on the machine.

[0003] After searching, it was found that the nozzle is cylindrical and two parallel planes were cut on both sides for disassembly with a wrench. However, the width of the plane is small and the spacing between the nozzles is small. When using a traditional wrench for disassembly and assembly, the small disassembly and assembly angle is inconvenient to operate, resulting in slow disassembly and assembly. At the same time, there is also the problem of the wrench not being tightened and slipping, causing wear of the nozzle, and uneven force during disassembly and assembly, resulting in deformation.

[0004] There is an urgent need for a linear source crucible cover cleaning nozzle disassembly and assembly fixture to solve the technical defects raised in the above technology. Utility Model Content

[0005] The purpose of the utility model is to provide a disassembly and assembly jig for cleaning a line source crucible cover nozzle, so as to solve the problem in the above background technology that the nozzle is easily damaged during disassembly.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a linear source crucible cover cleaning nozzle disassembly and assembly jig, comprising a disassembly sleeve, a fixing rod fixedly welded to the top of the disassembly sleeve, a mounting sleeve fixedly welded to the top of the fixing rod, a hand-held rod installed inside the mounting sleeve, a positioning hole provided at the front end of the hand-held rod, a positioning bolt provided at the front end of the mounting sleeve, anti-slip sleeves installed on both sides of the hand-held rod, and a reserved groove provided inside the disassembly sleeve.

[0007] Preferably, the disassembly sleeve is made of steel, the reserved groove fits closely with the external dimensions of the nozzle, and the hand-held rod is made of stainless steel.

[0008] Preferably, seven groups of positioning holes are provided, and the positioning holes are distributed at equal intervals at the front end of the handheld rod.

[0009] Preferably, the positioning bolt passes through the mounting sleeve and is embedded in the positioning hole to be threadedly connected.

[0010] Preferably, the exterior of the disassembly sleeve is provided with a corrosion-resistant layer, and the interior of the reserved groove is provided with a wear-resistant coating.

[0011] Preferably, the anti-slip sleeve is sleeved on the outside of the hand-held rod, and the outside of the anti-slip sleeve is provided with anti-slip grooves.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the linear source crucible cover cleaning nozzle disassembly and assembly jig not only realizes the function of easy disassembly and reduced damage, realizes the function of easy adjustment of torque, but also realizes the function of anti-slip and easy hand-holding;

[0013] (1) By providing a disassembly sleeve, a fixing rod, a hand-held rod and a reserved groove, the nozzle on the line source crucible cover is cylindrical, and two parallel planes are cut on both sides. When disassembling, the disassembly sleeve needs to be sleeved on the outside of the nozzle. The reserved groove inside the disassembly sleeve fits perfectly with the outside of the nozzle. When the staff rotates the hand-held rod, the disassembly sleeve can drive the nozzle to rotate and remove. The disassembly sleeve will not be loose or uneven in force, which greatly reduces the risk of damaging the nozzle during disassembly and assembly;

[0014] (2) By providing a hand-held rod, a positioning hole, a mounting sleeve and a positioning bolt, when the staff uses a disassembly and assembly jig to disassemble the nozzle of the line source crucible cover, it is necessary to first put the disassembly sleeve on the outside of the nozzle, and then hold the hand-held rod to drive the disassembly sleeve to rotate to unscrew the nozzle. The installation position of the hand-held rod is adjustable. Adjusting the hand-held rod can adjust the torque of the staff to rotate the disassembly sleeve. When adjusting, first unscrew the positioning bolt, then move the hand-held rod to the appropriate position and then use the positioning bolt to fix it. This structure realizes the function of facilitating the adjustment of torque;

[0015] (3) By providing an anti-slip cover and anti-slip grooves, the anti-slip cover can be put on the outside of the hand-held rod for use, and can be removed from the outside of the hand-held rod when the anti-slip cover is not needed. The anti-slip cover is made of rubber material, and the staff can hold the anti-slip cover when using the disassembly jig. The material of the anti-slip cover and the anti-slip grooves on the outside can increase the friction of the hand-held, thereby improving the stability of disassembly.

[0023] The disassembly sleeve 1 is made of steel, the reserved groove 7 is closely fitted with the external dimensions of the nozzle, and the hand-held rod 3 is made of stainless steel;

[0024] Specifically, if Figure 1 and Figure 2 As shown, the nozzle on the line source crucible cover is cylindrical, and two sides are cut to form two parallel planes. When disassembling, the disassembly sleeve 1 needs to be put on the outside of the nozzle. The reserved groove 7 inside the disassembly sleeve 1 fits perfectly with the outside of the nozzle. When the staff rotates the handheld rod 3, the disassembly sleeve 1 can drive the nozzle to rotate and remove it. The disassembly sleeve 1 will not be loose or uneven in force, which greatly reduces the risk of damaging the nozzle during the disassembly and assembly process.

[0025] Embodiment 2: There are seven groups of positioning holes 4, which are evenly spaced at the front end of the handle 3. The positioning bolts 9 pass through the mounting sleeve 5 and are embedded in the positioning holes 4 to form a threaded connection.

[0026] Specifically, if Figure 1 and Figure 3As shown, when disassembling the nozzle, first put the disassembly sleeve 1 on the outside of the nozzle, then hold the hand-held rod 3 to drive the disassembly sleeve 1 to rotate and unscrew the nozzle. The installation position of the hand-held rod 3 is adjustable. By adjusting the hand-held rod 3, the torque of the staff to rotate the disassembly sleeve 1 can be adjusted. When adjusting, first unscrew the positioning bolt 9, then move the hand-held rod 3 to the appropriate position and then use the positioning bolt 9 to fix it.

[0027] Example 3: The exterior of the disassembly sleeve 1 is provided with a corrosion-resistant layer 11, the interior of the reserved groove 7 is provided with a wear-resistant coating 10, the anti-slip sleeve 6 is sleeved on the exterior of the hand-held rod 3, and the exterior of the anti-slip sleeve 6 is provided with anti-slip grooves 8;

[0028] Specifically, if Figure 1 、 Figure 2 and Figure 4 As shown, the anti-slip cover 6 can be put on the outside of the hand-held rod 3 for use. When the anti-slip cover 6 is not needed, it can be removed from the outside of the hand-held rod 3. The anti-slip cover 6 is made of rubber. When the staff uses the disassembly jig, they can hold the anti-slip cover 6. The material of the anti-slip cover 6 and the anti-slip pattern 8 on the outside can increase the friction of holding.

[0029] When the staff rotates the hand-held rod 3, the disassembly sleeve 1 can drive the nozzle to rotate and remove it. There is no problem of looseness and uneven force in the disassembly sleeve 1, which greatly reduces the risk of damage to the nozzle during disassembly and assembly.
