Description

TECHNICAL FIELD

[0001] The present application belongs to the field of medical tool detection, and particularly relates to a defect detection device for medicinal glass bottles. BACKGROUND

[0002] With the development of industrial technology, modern medical tool detection technology is developing more and more perfect, and medicinal glass bottles need to be precisely detected when they are shipped. The distortion of the profile of a medicinal glass bottle directly affects the capacity of the medicinal glass bottle, which can easily lead to inaccurate drug loading of the medicinal glass bottle. Therefore, it is necessary to detect whether the profile of the medicinal glass bottle is distorted.

[0003] The patent CN114460097B discloses a medicinal ampoule glass bottle detection device, which relates to the technical field of medicinal ampoule glass bottle detection. The device has the advantages of using a magnifying glass for measurement and improving detection accuracy. The technical scheme is as follows: a vertical rod is arranged on a desktop, a horizontal plate is arranged on the vertical rod, a vertical plate is slidably connected to the horizontal plate, parallel first and second placing plates are arranged at the upper and lower ends of the vertical plate, a magnifying glass is embedded in the first placing plate, a transparent observation plate is arranged on the second placing plate for observing the ampoule glass bottle below the second placing plate, and a driving member is arranged on the horizontal plate to drive the vertical plate to move along the length direction of the horizontal plate.

[0004] The device has the following defects in use: first, the detection of the glass bottle is not accurate, and the glass bottle can be easily broken when moving to the next station; second, the detection of the glass bottle is carried out in a constant temperature environment, and the glass bottle can be broken due to its own stress in the case of sudden temperature drop or rise. SUMMARY

[0005] The present application aims to solve the problems in the background art. The defect detection device for medicinal glass bottles comprises a suction rod, a copper ring, a metal spring, an electromagnet, an iron block, a buzzer and a red indicator light. Before the suction rod, the copper ring and the metal spring are inserted into the medicinal glass tube, the electromagnet is powered to attract the iron block and bend the metal spring inward. This allows the contact roller to retract inward and pass through the bottle opening. When the electromagnet is powered off, the metal spring returns to a straight state. If there is an uneven place on the inner wall of the medicinal glass tube, the contact roller and the metal spring will be bent. If the metal spring contacts the copper ring, it indicates that the profile of the medicinal glass tube is distorted. After the metal spring contacts the copper ring, the buzzer and the red indicator light are triggered. Therefore, unqualified medicinal glass tubes can be picked out by the staff, thereby solving the problems mentioned in the background art.

[0006] To solve the above problems, the present invention provides the following technical solution: a defect detection device for pharmaceutical glass bottles, comprising a feeding hopper, a conveying channel at the bottom of the feeding hopper, the top opening of the conveying channel connecting to the bottom opening of the feeding hopper, an observation mechanism on the front sidewall of the feeding hopper and the conveying channel, a vibration mechanism on the sidewall of the conveying channel, and a feeding mechanism at the right end of the conveying channel; three detection ports are provided on the front sidewall of the conveying channel, a contour detection mechanism on the sidewall of the left detection port, and expansion detection mechanisms on the sidewalls of the two right detection ports; the contour detection mechanism includes a detection platform on the front sidewall of the conveying channel, and a propulsion cylinder on the front sidewall of the detection platform; the propulsion cylinder... The cylinder's output end is equipped with a telescopic rod, and the end of the telescopic rod is equipped with a propulsion plate. Two copper plates are provided on the rear side wall of the propulsion plate, and two metal springs are provided on the outer side of the copper plates. The two sets of copper plates and metal springs are symmetrically arranged around the axis of the propulsion plate. A contact roller is provided on the outer side wall of the end of the metal spring, and a suction mechanism is provided on the inner side wall of the end of the metal spring. A copper square ring is provided on the end of the copper plate, and the copper square ring is fitted onto the outer side wall of the metal spring, with a gap between the inner side wall of the copper square ring and the outer side wall of the metal spring. The copper plate is connected to the positive terminal of a DC power supply, and the metal spring is connected to the negative terminal of a DC power supply. The power circuit is also connected to a power-on indicator mechanism. A medicine bottle rotation mechanism is provided above and below the propulsion plate.

[0007] In use, the pharmaceutical glass bottle to be processed is put into the hopper. The last bottle stops at the discharge channel. The propulsion cylinder drives the propulsion disc forward a distance, allowing the copper sheet and metal spring to be inserted into the pharmaceutical glass tube. During the rotation of the pharmaceutical glass bottle driven by the rotating mechanism, there are uneven parts on the inner wall of the pharmaceutical glass bottle, which will cause it to bend due to contact with the roller and metal spring. If the metal spring contacts the copper square ring, it indicates that the outline of the pharmaceutical glass tube is excessively twisted. After the metal spring contacts the copper square ring, it will be energized and trigger the energization indicator mechanism, so that the operator can pick out the unqualified pharmaceutical glass tube.

[0008] Furthermore, the medicine bottle rotation mechanism includes a torsion bridge fixedly installed on the upper and lower side walls of the conveying channel. A pressing cylinder is installed on the side wall of the torsion bridge facing away from the conveying channel. A pressing plate is installed at the end of the telescopic rod of the pressing cylinder. Two forked shaft brackets are installed at the end of the pressing plate. A torsion motor is installed on the side wall of each forked shaft bracket. A torsion roller is installed on the output shaft of the torsion motor. Torsion grooves matching the torsion rollers are installed on the upper and lower side walls of the conveying channel.

[0009] During use, the pressing cylinder drives the pressing plate toward the torsion groove until the four torsion rollers are inserted into the torsion groove and adhere to the outer wall of the pharmaceutical glass bottle. At the same time, the four torsion motors drive the torsion rollers to rotate and drive the pharmaceutical glass tube held inside to rotate.

[0010] Furthermore, the observation mechanism includes an observation notch on the front side wall of the feed hopper, with a glass plate inserted inside the observation notch, and a wire groove is provided on the front side wall of the conveying channel.

[0011] If a pharmaceutical glass bottle gets stuck or breaks during transport, staff can spot the problem by observing the location of the notch and the groove, and then remove the damaged bottle.

[0012] Furthermore, the vibration mechanism includes two vibration motors, one of which is located at the top of the conveying channel and the other at the bottom of the conveying channel.

[0013] During use, the pharmaceutical glass bottle is continuously conveyed into the conveying channel by a vibrating motor.

[0014] Furthermore, the feeding mechanism includes a feeding channel at the end of the conveying channel, a feeding cylinder is provided on the front side wall of the feeding channel, and a push rod is provided at the output end of the feeding cylinder, which can extend into the interior of the feeding channel.

[0015] During use, the completed pharmaceutical glass bottles are pushed down by the push rod of the feeding cylinder, and the bottles slide out along the feeding channel for collection.

[0016] Furthermore, the attraction mechanism includes an attraction rod at the center of the propulsion disk, an electromagnet is provided at the end of the attraction rod, and an iron block is provided on the inner side wall of the end of the metal spring, and the electromagnet and the two iron blocks can be attracted by electricity.

[0017] When in use, before the suction rod, copper sheet and metal spring are inserted into the medicine glass tube, the electromagnet is energized to attract the iron block, causing the metal spring to bend inward. This allows the resisting roller to retract inward and pass through the bottle mouth. When the electromagnet is de-energized, the metal spring returns to its straight state.

[0018] Furthermore, the power-on indicator mechanism includes a buzzer and a red indicator light connected to the power supply circuit.

[0019] When in use, the metal spring contacts the copper square ring, which will energize and trigger the buzzer and red indicator light, allowing staff to pick out the substandard medical glass tubes.

[0020] Furthermore, the expansion detection mechanism includes an expansion platform on the front side wall of the conveying channel. An electric push rod is provided on the outer side wall of the expansion platform. A propulsion head is provided on the telescopic rod of the electric push rod. A central rod is provided on the side wall of the propulsion head. An air bladder is provided on the outer side of the central rod. An air machine is provided at the top of the conveying channel. The air machine is connected to the inside of the air bladder through an air supply pipe and the propulsion head. The air temperature output by the air machine on the left is 30 degrees Celsius, and the air temperature output by the air machine on the right is 90 degrees Celsius.

[0021] During use, the electric push rod drives the push head, center rod, and air bladder to insert into the pharmaceutical glass tube. At this time, the air pump starts to inject high-pressure air into the air bladder through the air supply pipe, which can then detect whether the pharmaceutical glass tube can be burst. The air temperature injected into the air bladder a second time is 90 degrees Celsius, which can then detect whether the pharmaceutical glass tube has cracks after a sudden temperature change, and can also detect whether the pharmaceutical glass tube still has the ability to resist bursting after a sudden temperature change.

[0022] Compared with the prior art, the embodiments of this application have the following main advantages:

[0023] Firstly, when using this device, the pharmaceutical glass bottles to be processed are fed into the hopper. Under the action of the vibrating motor, the bottles are continuously conveyed into the conveying channel. The last bottle stops at the discharge channel. Simultaneously, the pressing cylinder drives the pressing plate towards the torsion groove until four torsion rollers are inserted into the torsion groove and adhere to the outer wall of the pharmaceutical glass bottle. Four torsion motors simultaneously drive the torsion rollers to rotate, which in turn drives the internally clamped pharmaceutical glass tube to rotate. The pushing cylinder drives the pushing disc forward a certain distance, allowing the suction rod, copper sheet, and metal spring to insert into the pharmaceutical glass. Inside the tube, before the suction rod, copper sheet, and metal spring are inserted into the pharmaceutical glass tube, the electromagnet is energized to attract the iron block, causing the metal spring to bend inward. This allows the contact roller to retract inward and pass through the bottle opening. When the electromagnet is de-energized, the metal spring returns to its straight state. If there are uneven areas on the inner wall of the pharmaceutical glass bottle, the contact roller and metal spring will bend. If the metal spring contacts the copper square ring, it indicates that the outline of the pharmaceutical glass tube is excessively distorted. After the metal spring contacts the copper square ring, it will energize and trigger the buzzer and red indicator light, allowing the staff to pick out the substandard pharmaceutical glass tubes.

[0024] Secondly, the electric push rod drives the push head, center rod and airbag to be inserted into the medicine glass tube. At this time, the air machine starts to inject high-pressure air into the airbag through the air supply pipe, so as to detect whether the medicine glass tube can be burst. The air temperature injected into the airbag for the second insertion is 90 degrees, so as to detect whether the medicine glass tube has cracks after a sudden temperature change, and can also detect whether the medicine glass tube still has the ability to resist bursting after a sudden temperature change.

During the rotation of the pharmaceutical glass bottle driven by the rotating mechanism, there are uneven parts on the inner side wall of the pharmaceutical glass bottle, which will cause it to bend due to contact with the roller 408 and the metal spring 406. If the metal spring 406 contacts the copper square ring 410, it indicates that the outline of the pharmaceutical glass tube is excessively twisted. After the metal spring 406 contacts the copper square ring 410, it will be energized and trigger the energization indicator mechanism, so that the workers can pick out the unqualified pharmaceutical glass tubes.

[0039] In further embodiments of the present invention, such as Figures 1-3 As shown, the medicine bottle rotating mechanism includes a torsion bridge 6 fixedly installed on the upper and lower side walls of the conveying channel 2. A pressing cylinder 601 is installed on the side wall of the torsion bridge 6 facing away from the conveying channel 2.

[0040] In this embodiment, the pressing cylinder 601 drives the pressing plate 602 to move toward the twist groove 605 until the four twisting rollers 604 are inserted into the twist groove 605 and attached to the outer wall of the pharmaceutical glass bottle. At the same time, the four twisting motors 603 drive the twisting rollers 604 to rotate and drive the pharmaceutical glass tube clamped inside to rotate.

[0041] In further embodiments of the present invention, such as Figure 1 , 4 As shown, the observation mechanism includes an observation notch 101 on the front side wall of the feed hopper 1, and a glass plate is installed inside the observation notch 101.

[0047] In further embodiments of the present invention, such as Figures 6-7 As shown, the attraction mechanism includes an attraction rod 404 at the center of the push plate 403. An electromagnet 407 is provided at the end of the attraction rod 404, and an iron block 409 is provided on the inner side wall of the end of the metal spring 406. The electromagnet 407 and the two iron blocks 409 can be attracted together by electricity.

[0048] In this embodiment, before the suction rod 404, copper sheet 405 and metal spring 406 are inserted into the pharmaceutical glass tube, the electromagnet 407 is energized to attract the iron block 409, causing the metal spring 406 to bend inward. This allows the abutment roller 408 to retract inward and pass through the bottle mouth. When the electromagnet 407 is de-energized, the metal spring 406 returns to its straight state.

[0049] In a further embodiment of the present invention, the power-on indicator mechanism includes a buzzer and a red indicator light connected to the power supply circuit.

[0052] In this embodiment, the electric push rod drives the push head 503, the center rod 504 and the air bag 505 to be inserted into the pharmaceutical glass tube. At this time, the air pump 501 starts to inject high-pressure air into the air bag 505 through the air supply pipe 502, so as to detect whether the pharmaceutical glass tube can be burst. The air temperature injected into the air bag 505 for the second insertion is 90 degrees, so as to detect whether the pharmaceutical glass tube has cracks after a sudden temperature change, and can also detect that the pharmaceutical glass tube still has the ability to resist bursting after a sudden temperature change.
