Description

Technical Field

[0001] The invention relates to the technical field of glass bottle quality inspection, and in particular to an online quality inspection mechanism for glass bottles. Background Art

[0002] With the continuous development of the pharmaceutical industry, the requirements for various types of drug packaging are getting higher and higher, especially the quality inspection of pharmaceutical glass bottles that are easy to cause drug deterioration. After the pharmaceutical glass bottles come off the production line, they need to be inspected for defects such as cracks or flaws. In order to reduce the workload of personnel, the existing technology usually uses an online quality inspection mechanism for glass bottles to automatically inspect them. The basic principle is to place the glass bottles to be inspected on a conveyor and then cooperate with the inspection camera for inspection, which improves the inspection efficiency while reducing the workload of personnel.

[0003] Although the above-mentioned existing online quality inspection mechanism for glass bottles can automatically inspect, reduce the workload of personnel and improve the inspection efficiency, since the inspection camera is usually fixed at a certain position, it is impossible to ensure that the glass bottles are always transported on the same horizontal line during loading. This makes it impossible for the inspection camera to fully inspect the glass bottles, which makes it easy to miss inspections, thereby reducing the inspection accuracy.

[0004] Therefore, we designed an online quality inspection mechanism for glass bottles to solve the above problems. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect" and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] See also Figure 1-6 The present invention provides a technical solution: an online quality inspection mechanism for glass bottles, comprising an inspection frame 1, a conveyor installed on the top of the inspection frame 1, and a quality inspection component installed on the top of the conveyor, and also comprising: A lifting frame 2 is fixedly mounted on the rear end of the top of the detection frame 1 in the vertical direction; The slide 3 is arranged at the front side of the lifting frame 2, and the slide 3 is located above the conveyor; There are two direction-adjusting members 4, which are obliquely and symmetrically arranged above the conveyor and are used to adjust the position of the glass bottles to be inspected being conveyed, and one of the direction-adjusting members 4 is connected to the sliding member 3; The guide members 5 have the same number as the direction-adjusting members 4 and are fixedly mounted on the ends of the direction-adjusting members 4; The number of fixed columns 6 corresponds to that of the guide members 5 and is fixedly mounted on the top of the guide members 5. A slider 7 is fixedly mounted on the top of the fixed columns 6, and an adjusting member 8 is sleeved on the slider 7. The quality inspection component includes a U-shaped frame 19, which is fixedly mounted on the top of the inspection frame 1. A CCD inspection camera 20 is arranged on the U-shaped frame 19. The CCD inspection camera 20 is located above the conveyor. A signal light 21 is arranged on the U-shaped frame 19. The signal light 21 is electrically connected to the CCD inspection camera 20. The conveyor includes two rotating rollers 22, which are symmetrically mounted on the detection frame 1. Belts 23 are tightened and sleeved on the two rotating rollers 22. A protective box 24 is fixedly mounted on one side of the detection frame 1. A motor is arranged in the protective box 24, and the motor is transmission-connected to one of the rotating rollers 22.

[0024] In the specific implementation, firstly, a plurality of glass bottles to be inspected are placed on the top of the belt 23 in sequence, and then the motor is turned on to rotate the rotating roller 22 to drive the belt 23 to move, so that the glass bottles can be conveniently transported. During the transportation process, the two inclined direction adjusting members 4 can block the offset glass bottles and guide them to the center position on the belt 23. Then the glass bottles will be transported in a directed manner between the two guide members 5, and finally they will be inspected by the CCD inspection camera 20. In this process, there is no need for personnel to manually intervene in the position of the glass bottles, and the glass bottles can be automatically adjusted to the same horizontal line, thereby avoiding the problem of missed detection by the CCD inspection camera 20 and improving the detection accuracy.

[0025] It should be noted here that the CCD inspection camera 20 is an industrial camera used in a variety of inspection scenarios. It is used to detect defects such as scratches, cracks, burrs, deformation, glue deficiency, dirt, etc. on the surface of products. Its basic principle is: determine whether the object to be inspected is in the center of the field of view of the industrial camera, and send a pulse signal to the image acquisition device. The acquisition device starts the pulse and sends it to the industrial camera and lighting equipment. The industrial camera starts scanning, and the image is scanned and output after exposure. The output signal type is determined and processed accordingly. The image signal is sent to the data buffer, and the processor or computer performs image processing and display. The computer processes, analyzes and recognizes the image, obtains measurement results or logical control variables, and controls other devices to complete related actions. When a glass bottle with a crack is detected, the signal light 21 can be flashed to remind personnel to remove defective products. Since the CCD inspection camera 20 is a prior art and is not a problem that needs to be solved in the background technology of this specification, it will not be elaborated in detail.

[0026] In addition, in order to facilitate personnel to find defective products, a display screen can be set on one side of the U-shaped frame 19, and the display screen can be connected to the CCD detection camera 20 line. The data detected by the CCD detection camera 20 can be fed back to the display screen, thereby facilitating personnel to quickly find defective products.

[0027] See also Figure 1-6As shown, a threaded screw 9 is rotatably provided on the front side of the lifting frame 2, and the slide 3 is threadedly sleeved on the threaded screw 9. A motor 10 is fixedly installed on the top of the lifting frame 2. The driving shaft of the motor 10 is transmission-connected to one end of the threaded screw 9. A limiter is inserted in the slide 3, and the limiter is arranged in the lifting frame 2. A slide groove 11 is opened on the front side of the lifting frame 2. The threaded screw 9 is rotatably installed in the slide groove 11, and the slide 3 is slidably inserted in the slide groove 11. The limiter includes a guide rod 12, which is inserted in the slide 3, and both ends of the guide rod 12 are fixedly installed in the slide groove 11.

[0028] In specific implementation, based on the above implementation, by turning on the motor 10, the threaded screw 9 rotates, so that the slide 3 can drive the adjustment member 4 and the guide member 5 to rise and fall, and can guide glass bottles of different heights, thereby improving the scope of application.

[0029] See also Figure 1-6 The two adjusting members 4 are provided with a plurality of placement grooves on opposite sides thereof, and guide wheels 13 are rotatably mounted in the placement grooves, and part of the guide wheels 13 is located outside the placement grooves. By providing the guide wheels 13, the friction of the glass bottle can be reduced when it slides along the adjusting member 4, thereby effectively reducing the wear on the glass bottle, and facilitating the CCD detection camera 20 to detect the glass bottle.

[0030] See also Figure 1-6 The two guide members 5 are provided with cleaning members 14 on opposite sides thereof. The cleaning members 14 are wiping sponges. By providing the cleaning members 14, the outer surface of the glass bottle during the conveying process can be wiped, and the adhered dust can be wiped off, thereby further improving the detection effect of the CCD detection camera 20.

[0031] It should be noted here that in order to prevent the cleaning piece 14 from being unable to be wiped normally due to excessive dust adhesion, we can set a sub-Velcro on one side of the guide piece 5, and then set a mother Velcro on one side of the cleaning piece 14. When in use, the cleaning piece 14 is installed on the guide piece 5 through the sub-Velcro and the mother Velcro. When replacement is needed, just follow the above principle to ensure continuous wiping of the glass bottle.

[0032] See also Figure 1-6A bidirectional screw rod 16 is rotatably installed on one side of the adjusting member 8, and the slider 7 is threadedly sleeved on the bidirectional screw rod 16. A motor 17 is fixedly installed on one side of the adjusting member 8. The driving shaft of the motor 17 is transmission-connected to one end of the bidirectional screw rod 16. A guide member is inserted in the slider 7, and the guide member is arranged in the adjusting member 8. A limit rail 25 is provided on one side of the slide 3, and one of the direction-adjusting members 4 is slidably inserted in the limit rail 25. A support rod 26 is fixedly installed in the limit rail 25, and the direction-adjusting member 4 is slidably sleeved on the support rod 26. An adjusting groove 15 is provided on one side of the adjusting member 8, and the bidirectional screw rod 16 is rotatably installed in the adjusting groove 15. The slider 7 is slidably inserted in the adjusting groove 15. The guide member includes a guide rod 18, which is inserted in the slider 7, and both ends of the guide rod 18 are fixedly installed in the adjusting groove 15.

[0033] In specific implementation, on the basis of the above implementation, by turning on the motor 17, the bidirectional screw 16 is rotated, so that the two sliders 7 will drive the fixed column 6, the guide member 5 and the adjustment member 4 to move away from or approach each other along the direction set by the guide rod 18. During this process, one of the adjustment members 4 can slide in the limit rail 25 along the direction set by the support rod 26, and the distance between the two adjustment members 4 and the guide member 5 can be adjusted, so that it can be suitable for glass bottles of different widths, thereby further improving its scope of application.

[0034] Before use, the electrical appliances involved in the online quality inspection mechanism need to be connected to an external power supply. A battery pack can also be installed on the inspection frame 1 in an area that does not hinder the operation of other components, and a protective film can be wrapped on the battery pack. The battery pack is then electrically connected to the electrical appliances through a line to power the electrical appliances, thereby ensuring the normal operation of the electrical appliances. Since connecting electrical appliances to an external power supply or installing a battery pack are both existing technologies and are not problems that need to be solved in the background technology of this specification, they will not be elaborated on.

[0035] Working principle: When in use, first place multiple glass bottles to be inspected on the top of the belt 23 in sequence, then turn on the motor to rotate the rotating roller 22 to drive the belt 23 to move, which can facilitate the transportation of the glass bottles. During the transportation process, the two tilted adjustment members 4 can block the offset glass bottles and guide them to the center position on the belt 23. Then the glass bottles will be transported along the two guide members 5, and finally cooperate with the CCD detection camera 20 to detect them. In this process, there is no need for personnel to manually intervene in the position of the glass bottles. The glass bottles can be automatically adjusted to the same horizontal line, thereby avoiding the problem of missed detection by the CCD detection camera 20 and improving the detection accuracy; It should be noted here that by providing the guide wheel 13, the friction of the glass bottle when sliding along the direction adjustment member 4 can be reduced, thereby effectively reducing the wear on the glass bottle and facilitating the CCD detection camera 20 to detect the glass bottle; In addition, it should be noted that, by providing the cleaning member 14 , the outer surface of the glass bottle during the transportation process can be wiped, and the adhered dust can be wiped off, thereby further improving the detection effect of the CCD detection camera 20 .

[0036] By turning on the motor 10 and rotating the threaded screw 9, the slide 3 can drive the direction-adjusting member 4 and the guide member 5 to rise and fall, and can guide glass bottles of different heights, thereby improving the scope of application. By turning on the motor 17 and rotating the bidirectional screw 16, the two slide blocks 7 can drive the fixed column 6, the guide member 5 and the direction-adjusting member 4 to move away from or closer to each other along the direction in which the guide rod 18 is set. During this process, one of the direction-adjusting members 4 can slide in the limit rail 25 along the direction in which the support rod 26 is set, and the distance between the two direction-adjusting members 4 and the guide member 5 can be adjusted, so that it can be suitable for glass bottles of different widths, thereby further improving its scope of application.
