[0033] The utility model provides the following preferred embodiments:

[0034] Embodiment 1, as Figure 1-Figure 7 As shown, an automatic capping device for photoresist products includes a first conveyor belt 11, through which gallon bottles to be capped can be conveyed, and the filled gallon bottles can be automatically conveyed to the capping station, and also includes a side plate 15, a column 14, a feeding mechanism, a tightening mechanism and a positioning mechanism, the column 14 is fixed to the top of one side of the first conveyor belt 11, and the side plate 15 is installed on one side of the column 14;

[0035] The tightening mechanism includes an electric clamp 26, a mounting plate 20, a rotating assembly and a lifting assembly. The mounting plate 20 is slidably arranged on one side of the side plate 15. The electric clamp 26 is located below the mounting plate 20 and is rotatably connected to the mounting plate 20 through a bearing. The rotating assembly is located between the mounting plate 20 and the electric clamp 26. The lifting assembly is installed between the mounting plate 20 and the side plate 15. The rotating assembly is used to drive the electric clamp 26 to rotate, and the lifting assembly is used to drive the electric clamp 26 to rise and fall. At the same time, the electric clamp 26 can grasp the bottle cap, so that the bottle cap can be tightened by the cooperation of the rotating assembly, the lifting assembly and the electric clamp 26.

[0036] The feeding mechanism includes a second conveyor belt 12, a feeding plate 27, a baffle 29 and a pushing assembly. The second conveyor belt 12 is fixed to one side of the first conveyor belt 11 and is located at the top of the first conveyor belt 11. The second conveyor belt 12 is used to transport bottle caps. The feeding plate 27 is located at one end of the second conveyor belt 12 close to the column 14, and the feeding plate 27 is slidably arranged on the column 14. The baffle 29 is fixedly installed at the top of the feeding plate 27 and close to one side of the second conveyor belt 12. The baffle 29 is used to block the bottle caps on the second conveyor belt 12. The pushing assembly is located between the feeding plate 27 and the column 14. The bottle caps above the second conveyor belt 12 can be moved to the top of the feeding plate 27. When the pushing assembly is working, it can drive the feeding plate 27 to move, so that the bottle caps on the feeding plate 27 can be pushed to the capping station;

[0037] The feeding mechanism can automatically convey the bottle caps one by one to the top of the capping station and align them with the mouth of the gallon bottle. The tightening mechanism can drive the caps to rotate to tighten the bottle caps.

[0038] The positioning mechanism includes two positioning plates 32 and two telescopic components. The two positioning plates 32 are symmetrically arranged on both sides below the electric clamp 26. Each telescopic component is installed on one side of a positioning plate 32. The telescopic components can drive the positioning plates 32 to move, so that the two positioning plates 32 can be moved to both sides of the gallon bottle to be capped, thereby realizing the positioning of the gallon bottle and ensuring the stability of the subsequent capping.

[0039] like Figure 1-Figure 7 As shown, the pushing assembly includes a second cylinder 28 and a push plate 39. The second cylinder 28 is fixedly installed on one side of the column 14, and the push plate 39 is fixedly installed on the end of the feeding plate 27 away from the side plate 15. The output end of the second cylinder 28 is fixedly connected to the push plate 39. When the second cylinder 28 is working, it can drive the feeding plate 27 to move through the push plate 39 to realize the feeding of the bottle caps.

[0040] like Figure 1-Figure 7 As shown, the end of the baffle plate 29 away from the push plate 39 forms a channel for the bottle caps to move, and the width of the feed plate 27 matches the outer diameter of a single bottle cap. When in use, when the feed plate 27 is moving, the channel is first aligned with the second conveyor belt 12. When the second conveyor belt 12 is transporting the bottle caps, since the width of the feed plate 27 matches the outer diameter of a single bottle cap, the first bottle cap on the second conveyor belt 12 will be moved onto the feed plate 27, and then the second cylinder 28 drives the feed plate 27 to move, so that the feed plate 27 can push the bottle caps on the feed plate 27 to the capping station for subsequent capping operations. At the same time, the feed plate 27 can drive the baffle plate 29 to move when moving, so that the baffle plate 29 can block the second conveyor belt 12, that is, the bottle caps can be loaded one by one.

[0041] like Figure 1-Figure 7As shown, the rotating assembly includes a motor 21, a first gear 22, a second gear 23 and a rotating shaft 24. The rotating shaft 24 is rotatably arranged at the bottom end of the mounting plate 20 through a bearing. The electric clamp 26 is fixedly mounted at the bottom end of the rotating shaft 24. The second gear 23 is fixedly sleeved on the surface of the rotating shaft 24. The first gear 22 is rotatably arranged below the mounting plate 20, and the first gear 22 and the second gear 23 are meshed with each other. The motor 21 is fixedly mounted on the top of the mounting plate 20, and the output end of the motor 21 is fixedly connected to the first gear 22. When the electric clamp 26 needs to rotate, the motor 21 is controlled to work, and the motor 21 can drive the first gear 22 to rotate. Since the first gear 22 and the second gear 23 are meshed with each other, the first gear 22 can drive the second gear 23 to rotate when it rotates, so that the rotating shaft 24 can drive the electric clamp 26 to rotate, thereby rotating the bottle cap clamped in the electric clamp 26.

[0042] like Figure 1-Figure 7 As shown, an angle sensor 25 for detecting the rotation angle of the rotating shaft 24 is installed below the mounting plate 20 and on the surface of the rotating shaft 24. The angle sensor 25 can detect the rotation angle of the rotating shaft 24 and can detect the tightening parameters during the capping process.

[0043] like Figure 1-Figure 7 As shown, the lifting assembly includes a first cylinder 16, a sleeve rod 17 and an insertion rod 18. The first cylinder 16 is fixedly mounted on a side surface of the side plate 15, the output end of the first cylinder 16 is fixedly connected to the top end of the sleeve rod 17, the insertion rod 18 is inserted into the inside of the sleeve rod 17, and the bottom end of the insertion rod 18 is fixedly connected to the mounting plate 20.

[0044] like Figure 1-Figure 7 As shown, a force sensor 19 is fixed between the insertion rod 18 and the sleeve rod 17. The force sensor 19 can detect the force of screwing the cap. When the electric clamp 26 needs to move downward to screw the cap, the first cylinder 16 is controlled to work. The first cylinder 16 can drive the sleeve rod 17 to move downward, and the mounting plate 20 can be driven downward through the insertion rod 18, thereby driving the electric clamp 26 to move downward, and the rotating assembly can drive the cap to rotate to tighten the bottle cap.

[0045] like Figure 1-Figure 7As shown, each telescopic assembly includes a fixed seat 30, a third cylinder 31, two vertical plates 34 and two guide rods 33. The fixed seat 30 is fixedly installed on one side of the first conveyor belt 11, and the third cylinder 31 is fixedly installed on the top of the fixed seat 30. The output end of the third cylinder 31 is fixedly connected to the positioning plate 32. When the bottle cap needs to be positioned, the third cylinder 31 is controlled to work, and the third cylinder 31 can drive the positioning plate 32 to move, so that the positioning plate 32 can contact the bottle body to fix the bottle body, thereby ensuring the stability of the bottle body during the capping process. The two vertical plates 34 are symmetrically fixed on the top of the fixed seat 30, and each guide rod 33 is slidably set on a vertical plate 34. One end of each guide rod 33 is fixedly connected to the positioning plate 32. When the positioning plate 32 moves, it can drive the guide rod 33 to slide inside the vertical plate 34 to play a guiding role.

[0046] like Figure 1-Figure 7 As shown, a through-beam laser sensor 35 is fixed to the top of each fixing seat 30. The through-beam laser sensor 35 can detect the position of the bottle mouth, thereby realizing the alignment between the bottle cap and the bottle mouth.

[0047] like Figure 1-Figure 7 As shown, a protective cover 13 is detachably installed on the top of the column 14 by bolts, and the four sides of the protective cover 13 are made of transparent materials. A mounting frame is fixed under the second conveyor belt 12, and an emergency stop button 37 and an alarm 38 are installed on the mounting frame. By setting safety protection measures such as the protective cover 13, the emergency stop button 37 and the alarm 38, the operator can be prevented from being injured during the operation of the equipment. A jamming wheel 36 is installed on the rotating shaft of the first conveyor belt 11 and the second conveyor belt 12, and a rotation detector is installed inside the jamming wheel 36. When the conveyor belt operates normally, several rotating shafts and the conveying rollers of the rotating shafts are continuously rotating, so the jamming wheel is also continuously rotating. When the conveyor belt is stuck, the rotating shaft no longer rotates, and the jamming wheel stops rotating accordingly. At this time, when the rotation detector detects that the jamming wheel does not rotate, that is, when the rotating shaft and the conveying rollers on the rotating shaft stop rotating, it is determined that the conveyor belt is stuck, so that the equipment has fault self-diagnosis and alarm functions to ensure the reliability and safety of the equipment.

[0048] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
