Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a photoresist mixer. Background Art

[0002] When the existing photoresist stirring device is filled with photoresist and needs to perform a stirring operation, it is necessary to close the tank cover with a stirring roller on the upper end of the stirring tank in advance so that the two are sealed before the stirring operation can be performed.

[0003] However, since the closed lid and the mixing tank have a simple closing method, it is easy for the closed parts to become loose and reveal gaps, which can easily cause the photoresist to overflow from the gaps during stirring.

[0004] Therefore, the conventional photoresist stirring device can be improved so as to avoid the above-mentioned problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] The utility model provides a technical solution, please refer to Figure 1-4 :

[0025] A photoresist mixer comprises a base 1, on which an electric push rod 4 is mounted, and a fixing plate 5 is fixed to the end of the electric push rod 4, on which a rotating rod 6 driven to rotate by a motor is arranged, and a polygonal groove 7 is provided at the bottom of the rotating rod 6, and a placement groove 2 matched with a stirring tank 8 is arranged on the base 1, and a card slot 3 matched with a card block 9 fixed to the outer wall of the stirring tank 8 is also provided on the base 1, a rotating rod 10 is rotatably connected in the stirring tank 8, and a stirring blade 11 is fixed to the rotating rod 10, and a polygonal block 12 is fixed to the top of the rotating rod 10, the tank mouth of the stirring tank 8 is closed by a cover plate 13, a sealing ring is provided on the bottom of the cover plate 13 and the contact part with the inner wall of the stirring tank 8 is provided, and an adjusting member for adjusting the position of the cover plate 13 is provided on the fixing plate 5.

[0026] Embodiment 2:

[0027] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the adjusting member includes a vertical rod 15 rotatably connected to the fixing plate 5, and the vertical rod 15 is connected to the cover plate 13 by threads, and the cover plate 13 is slidably connected to the rotating rod 6 and the rotating rod 10, and a limiting member for limiting the vertical rod 15 is also provided on the fixing plate 5. By rotating the vertical rod 15, the cover plate 13 can be moved in the vertical direction until the cover plate 13 closes the tank opening of the mixing tank 8.

[0028] Embodiment three:

[0029] The technical solution is basically the same as that of the first embodiment, except that Figure 2As shown, the limiting member includes a bent block 14 fixed on the fixed plate 5, and the bent block 14 is rotatably connected to the vertical rod 15, a fixed disk 16 is fixed on the vertical rod 15, and a notch 17 is provided on the fixed disk 16, and a groove 18 matching the notch 17 is provided on the fixed plate 5, and a bottom rod 20 extends into the notch 17 and the groove 18. A slider 19 is slidably connected to the vertical rod 15, and the bottom of the slider 19 is fixed to the bottom of the slider 19, and a spring 21 is sleeved on the vertical rod 15. One end of the spring 21 abuts against the lower surface of the bent block 14, and the other end abuts against the upper surface of the slider 19. Under the elastic force of the spring 21, the bottom rod 20 moves downward, and the bottom rod 20 extends into the groove 18 through the notch 17, thereby playing a limiting effect on the fixed disk 16.

[0030] In summary, when the photoresist needs to be stirred, the raw materials can be placed in the stirring tank 8, and then the stirring tank 8 can be placed in the placement groove 2, and the block 9 is engaged with the groove 3.
