Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of contact lens care solution processing, in particular to a packaging film photoelectric detection mechanism for a contact lens care solution bottle. Background Art
[0002] After the contact lens care solution is canned into the bottle, it needs to be covered with a packaging film. Because the care solution belongs to the medical device industry, there are high requirements for product sealing packaging and product qualification rate. Conventional detection methods cannot effectively detect transparent plastic films that are tightly attached to the packaged objects, that is, packaging films, and have a high screening rate.
[0003] Therefore, a photoelectric detection mechanism for the packaging film of a contact lens care solution bottle is proposed to solve the above-mentioned problems. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a photoelectric detection mechanism for a packaging film of a contact lens care solution bottle, which has the advantages of being able to detect whether a packaging film is sleeved on a contact lens care solution bottle and to separate contact lens care solution bottles that are not sleeved with a packaging film from contact lens care solution bottles that are sleeved with a packaging film, thereby solving the above-mentioned problems.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a photoelectric detection mechanism for packaging film of contact lens care solution bottles, comprising a conveyor platform and a weighing seat, a first fixing rod and a second fixing rod being fixedly connected to the front side of the conveyor platform, two photoelectric switches and an electric push rod being fixedly connected to the top of the first fixing rod and the top of the second fixing rod respectively, and the electric push rod being connected to a power source via a lead through the photoelectric switch.
[0006] Furthermore, a care liquid bottle body is placed on the conveying platform, and a packaging film body is sleeved on the care liquid bottle body.
[0007] Furthermore, a shading plate is fixedly connected to the rear side of the conveying platform, and the shading plate corresponds to the photoelectric switch.
[0008] Furthermore, a third fixing rod is fixedly connected to the rear side of the conveying platform, a buffer bucket is fixedly connected to the bottom of the third fixing rod, and a through pipe is fixedly connected to the bottom of the buffer bucket.
[0009] Furthermore, a storage frame is provided on the top of the weighing seat, the inner bottom wall of the storage frame is an inclined surface, and the inside of the buffer bucket and the inner bottom of the storage frame are respectively provided with a first rubber layer and a second rubber layer.
[0010] Furthermore, an audible and visual indicator is arranged on the front side of the weighing seat.
[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0012] The packaging film photoelectric detection mechanism for the contact lens care solution bottle has a conveying platform driving the care solution bottle body to move, and the photoelectric switch emits infrared rays. The infrared rays are emitted to the care solution bottle body and are transmitted to the photoelectric switch after reflection. Because there is a gap between the packaging film body and the care solution bottle body and the materials are different, the care solution bottle body with or without the packaging film body has different reflection signals. If there is no packaging film body, the photoelectric switch is turned on, and the electric push rod pushes out the care solution bottle body without the packaging film body. The previous photoelectric switch is turned on for a longer time than the next photoelectric switch, and the time length is the time between the care solution bottle body being pushed by the conveying platform and passing through the two photoelectric switches. The two photoelectric switches are turned on at the same time, and the electric push rod is energized to avoid false triggering. The piston of the electric push rod pushes the care solution bottle body that is not sleeved with the packaging film body away from the conveying platform, and the care solution bottle body that is not sleeved with the packaging film body falls into the storage frame through the buffer bucket and the through pipe. When the weight of the care solution bottle body in the storage frame reaches the set value, the sound and light prompter sends out a sound and light warning to remind the user to take away the care solution bottle body temporarily stored in the storage frame.

DETAILED DESCRIPTION
[0017] 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 in 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.
[0018] See also Figure 1-3 , an embodiment provided by the utility model:
[0019] A photoelectric detection mechanism for packaging film of contact lens care solution bottles comprises a conveying platform 1 and a weighing seat 11. A first fixing rod 2 and a second fixing rod 4 are fixedly connected to the front side of the conveying platform 1. A photoelectric switch 3 and an electric push rod 5 are fixedly connected to the top of the first fixing rod 2 and the top of the second fixing rod 4 respectively. The electric push rod 5 is electrically connected to the photoelectric switch 3 through a wire.
[0020] Furthermore, the conveying platform 1 serves to convey the care solution bottle body 6 .
[0021] Furthermore, the first fixing rod 2 is fixedly connected to the photoelectric switch 3 to maintain the stability of the photoelectric switch 3. The photoelectric switch 3 serves to detect whether the packaging film body 601 is sleeved on the care liquid bottle body 6.
[0022] Furthermore, the second fixing rod 4 is fixedly connected to the electric push rod 5 to maintain the stability of the electric push rod 5. After the electric push rod 5 is started, the piston can be extended or retracted, and the body of the care liquid bottle 6 can be pushed away from the conveying platform 1.
[0023] Furthermore, the shading plate 7 serves to shield the light emitted by the photoelectric switch 3 .
[0024] Furthermore, the third fixing rod 8 is fixedly connected to the buffer bucket 9 to maintain the stability of the buffer bucket 9. A first rubber layer 901 is provided on the buffer bucket 9 to prevent the care liquid bottle body 6 from being damaged by collision. The through tube 10 serves to limit the falling trajectory of the care liquid bottle body 6.
[0025] Furthermore, the storage frame 12 serves to temporarily store the care solution bottle body 6 , and the second rubber layer 1201 prevents the care solution bottle body 6 from being damaged by collision.
[0026] Furthermore, the weighing base 11 plays the role of weighing the weight of the care liquid bottle body 6 in the storage frame 12. When the weighing base 11 measures that the weight of the care liquid bottle body 6 in the storage frame 12 reaches a certain threshold, the sound and light prompter 13 emits a prompt sound and a prompt light to remind the user to take away the care liquid bottle body 6 temporarily stored in the storage frame 12.
[0027] Working principle: the conveyor 1 drives the care liquid bottle body 6 to move, and the photoelectric switch 3 emits infrared rays. The infrared rays are emitted to the care liquid bottle body 6 and are transmitted to the photoelectric switch 3 after reflection. Because there is a gap between the packaging film body 601 and the care liquid bottle body 6 and the materials are different, the reflection signals of the care liquid bottle body 6 with or without the packaging film body 601 are different. If there is no packaging film body 601, the photoelectric switch 3 is turned on, and the electric push rod 5 pushes out the care liquid bottle body 6 without the packaging film body 601. The previous photoelectric switch 3 is turned on for a longer time than the next photoelectric switch 3, and the duration is the care liquid bottle body. 6 is pushed by the conveyor platform 1 through the time between the two photoelectric switches 3. The two photoelectric switches 3 are turned on at the same time, and the electric push rod 5 is energized to avoid false triggering. The piston of the electric push rod 5 pushes the care liquid bottle body 6 that is not sleeved with the packaging film body 601 away from the conveyor platform 1, and the care liquid bottle body 6 that is not sleeved with the packaging film body 601 falls into the storage frame 12 through the buffer bucket 9 and the through pipe 10. When the weight of the care liquid bottle body 6 in the storage frame 12 reaches the set value, the sound and light prompter 13 sends out a sound and light warning to remind the user to take away the care liquid bottle body 6 temporarily stored in the storage frame 12.
[0028] In summary, the packaging film photoelectric detection mechanism for contact lens care solution bottles can detect whether a packaging film is sleeved on the contact lens care solution bottle, and separate the contact lens care solution bottles that are not sleeved with the packaging film from the contact lens care solution bottles that are sleeved with the packaging film, etc., thus solving the problems raised in the background technology.
