Description

Technical Field

[0001] This utility model relates to the field of light inspection technology for soft bags, and in particular to a light inspection machine compatible with multiple types of soft bags. Background Technology

[0002] During the manufacturing process of soft bags used for infusion, some defective products may be produced. If these defective products are not detected and removed in time, the soft bag inspection machine is used for drug quality inspection. Unqualified products can affect human health and cause medical accidents. In the existing technology, inspection is usually carried out by human visual observation, which is not only inefficient but also prone to visual fatigue, resulting in poor detection accuracy. There are also some technologies that use external light sources and vision components of the equipment to observe the appearance of the product and remove defective products.

[0003] A utility model patent with publication number CN219455925U discloses an infusion bag detection device, which includes a light inspection device and a first conveying device, a rotary conveying device, and a second conveying device arranged sequentially. The first conveying device is inclined upwards along the conveying direction, and the second conveying device is inclined downwards along the conveying direction. Light inspection devices are provided on the upper side of both the first and second conveying devices. By using different angles, the detection of infusion bags is achieved, thereby eliminating the influence of external light and ensuring more accurate detection and a high detection rate. However, the above-mentioned technical solutions and related technologies still have many problems, such as: First, they are not applicable to different types and sizes of soft bags because the height and angle of the vision component and the light source component from the product are different for different types of soft bags. Therefore, a lot of time is required for debugging when changing products, which restricts the improvement of detection efficiency. Second, the products are generally conveyed by belts, which are easily damaged after long-term use and need to be replaced regularly. The belt installation structure in the prior art is complex, and replacement and disassembly are time-consuming and labor-intensive, affecting the normal use of the equipment. Utility Model Content

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] (1). This utility model adjusts the height of the inspection station from the conveyor belt by setting a lifting module. The lifting is controlled by the lifting power unit or manual wheel, thereby completing the position switching of each inspection station for different products. It is compatible with different types and models of soft bag products. The lifting power unit or manual wheel can be set to adjust the fixed parameters of the product to quickly adapt to the product replacement needs. In addition, by setting the belt assembly to be independently fixed on one side, when the conveyor belt needs to be disassembled, only the side support plate needs to be removed to complete the disassembly and assembly of the conveyor belt, saving time and effort, greatly improving the debugging efficiency and disassembly and assembly efficiency of the equipment, thereby improving the inspection efficiency of the equipment.

[0021] (2). This utility model achieves the adjustment of the length and tension of the conveyor belt by setting a tensioning component.

The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] To address the limitations of existing technologies, this embodiment provides a technical solution. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0043] This utility model is a technical improvement aimed at addressing many problems commonly found in existing light inspection equipment for detecting the appearance of infusion bags. These problems generally include the incompatibility of existing light inspection machines with multiple types of infusion bags. This is because different types of infusion bags require different camera shooting positions and light source illumination positions for inspection. Therefore, when changing the type of bag, all adjustments are required, which is cumbersome, time-consuming, and labor-intensive. In addition, the conveyor belt 203 is prone to wear after long-term use, so it needs to be removed and replaced regularly. However, the traditional conveyor belt 203 has a complex structure and cannot be quickly removed, thus affecting the normal use and inspection efficiency of the overall equipment.

[0044] See appendix Figure 1-2 A light inspection machine compatible with multiple types of soft bags includes: a belt assembly 200, mounted on a base 100 and including a conveyor belt 203 for conveying the soft bags to be inspected; an inspection station, mounted on the base 100 via a lifting module 800 and whose distance from the inspection station to the conveyor belt 203 is adjustable via the lifting module 800; the lifting module 800 includes a lifting power unit fixedly mounted relative to the base 100 and a sliding plate driven by the lifting power unit to move up and down, and the inspection station is fixedly mounted relative to the sliding plate.

[0045] See appendix Figure 3-5The belt assembly 200 includes several independently driven belt conveyor units connected end-to-end. Each belt conveyor unit is configured to be independently fixed on one side. One side is equipped with a belt drive component 202 to drive the conveyor belt 203, while the other side is fixedly supported by a side support plate 201. This connection can be understood as ensuring that the soft bags conveyed by the previous belt conveyor unit can be smoothly conveyed to the next belt conveyor unit. Furthermore, the belt drive component 202 is installed on one side of each belt conveyor unit to drive the conveyor belt 203, while the other side is fixedly supported by the side support plate 201. This means that the drive of the conveyor belt 203 is all installed on one side, while the other side is only supported and fixed by the side support plate 201. This facilitates easy disassembly and assembly by simply removing and installing the side support plate 201. A gap exists between the conveyor belts 203 of the two belt conveyor units. This gap is used for the camera to photograph the soft bags and allows the soft bags to pass through smoothly. Specifically, the conveyor belt 203 is rotatably mounted between the drive roller 209 and the adjusting roller 204. The drive roller 209 is rotatably mounted at both ends on the side uprights 208, with one end driven to rotate by the belt drive component 202. The adjusting roller 204 is rotatably mounted at both ends on adjusting extension plates 205 on the two side uprights 208. The position of the adjusting extension plates 205 on the side uprights 208 is adjusted by a tensioning component. The two side uprights 208 are respectively supported by side supports 210 and side support plates 201. 1. Mounted on the base 100. It can be understood that the adjusting roller 204 and the driving roller 209 are both located between the two side plates 208. The driving roller 209 is driven to rotate by the belt drive unit and its two ends are rotatably mounted between the two side plates 208. The two ends of the adjusting roller 204 are mounted on the side plates 208 through the adjusting extension plate 205. The two ends of the adjusting roller 204 are rotatably mounted on the side plates 208. Here, the belt drive unit 202 can be a rotary motor or other rotary drive unit. The tensioning assembly includes a fixed base 206 fixedly installed relative to the side plate 208 and a belt adjusting screw 207 spirally installed through the fixed base 206. The end of the belt adjusting screw 207 passes through the fixed base 206 and abuts against the adjusting extension plate 205. The adjusting extension plate 205 is provided with an elongated guide hole. The adjusting extension plate 205 and the side plate 208 are fastened together by an adjusting screw passing through the elongated guide hole. It can be understood that the fixed base 206 is fixedly installed with the side plate 208, the belt adjusting screw 207 is threadedly installed with the fixed base 206, and the end of the belt adjusting screw 207 abuts against the adjusting extension plate 205. When adjustment is needed, the belt adjusting screw 207 is rotated, and the belt adjusting screw 207 will move closer to or further away from the adjusting extension plate 205. At this time, the position of the adjusting extension plate 205 can be positioned by adjusting the position of the adjusting screw on the adjusting extension plate 205 and then tightening it.

[0046] See appendix Figure 1-2 The conveyor belt 203 includes an uphill section, a horizontal section, and a downhill section. The inspection stations include an inlet inspection station 300 at the inlet of the conveyor belt 203, inspection stations a400 and b500 on the uphill section, a bottle cap inspection station 600 on the horizontal section, inspection stations b500 and a400 on the downhill section, and a rejection station 700 at the outlet of the conveyor belt 203. It is understood that the bottoms of the uphill and downhill sections of the conveyor belt 203 are installed between the inclined base plate 101 and the machine base 100, i.e., the bottom of the inclined base plate 101 is installed on the machine base 100 via supports of different heights. The side supports 210 and side support plates 201 of the conveyor belt 203 are both installed on the inclined base plate 101. This allows for the setting of uphill and downhill sections. In the intermediate horizontal section, the side supports 210 and side support plates 201 of the belt conveyor unit are both mounted on a horizontal base plate. The bottom of this horizontal base plate is mounted on the machine base 100 via supports. The inlet inspection station 300 is used to inspect foreign objects and some appearance defects on the inner edge of the soft bag liquid. Inspection stations a400 and b500 are used to inspect foreign objects and appearance defects on the upper and lower surfaces of the soft bag liquid. The bottle cap inspection station 600 is used to inspect the appearance of the soft bag bottle caps. The rejection station 700 is used to reject unqualified soft bags. It is understood that the belt assembly 200 is equipped with a through-beam sensor before each inspection point to sense the product position and respond with visual imaging. See Appendix. Figure 3-5The entrance detection station 300 includes a main camera 302 that slides and rises with the slide plate, two side cameras 301, and two strip light sources 303 that are fixedly installed relative to the side plate 208. It can be understood that the two side cameras 301 are located on both sides of the main camera 302, and the strip light sources 303 are located on both sides of the conveyor belt 203. The main camera 302 is vertically slidably mounted on an adjusting support plate 3021, which is fixedly installed relative to the slide plate. The adjusting support plate 3021 has elongated holes. The adjusting screw passes through the elongated hole and is fixedly installed relative to the main camera 302. A main camera adjusting screw 3023 is also installed on the adjusting support plate 3021. This main camera adjusting screw 3023 passes through the adjusting support plate 3021 and is threadedly installed onto the lifting block 3022 of the main camera 302. It can be understood that the lifting block 3022 is fixedly installed relative to the main camera 302. When the main camera adjusting screw 3023 rotates, it drives the lifting block 3022 to rise and fall vertically, thereby adjusting the height of the main camera 302. The side-view camera 301 is installed at both ends in the arc-shaped positioning groove of the camera mounting plate by adjusting screws and is secured by adjusting screws. It can be understood that the side-view camera 301 is installed in the arc-shaped positioning groove of the camera mounting plate by adjusting screws. Loosening the adjusting screws allows the side-view camera 301 to slide along the arc-shaped groove with the adjusting screws, while tightening the adjusting screws allows the side-view camera 301 to be positioned on the camera mounting plate. See Appendix. Figure 6-8The detection station a400 includes a top camera 402 that slides and rises with the slide plate, and line light sources 900 located on both sides of the top camera 402. It also includes a U-shaped light source 401 located directly below the top camera 402. The line connecting the center of the U-shaped light source 401 and the top camera 402 passes through the gap between two adjacent conveyor belts 203. The position of the top camera 402 and the U-shaped light source 401 in the direction of the line connecting them is adjustable. It can be understood that the position adjustment of the top camera 402 is based on the same principle as the adjustment of the main camera 302, which is to adjust the height of the camera by rotating the adjusting screw. The two ends of the line light source 900 are installed in the arc-shaped positioning groove of the light source mounting plate 901 by adjusting screws and are fastened by adjusting screws. Loosening the adjusting screws allows the line light source 900 to slide along the arc-shaped positioning groove with the adjusting screws, and tightening the adjusting screws achieves the positioning of the line light source 900. The detection station b500 includes a top surface light source 502 that slides and rises with the slide plate, two line light sources 900 mounted on both sides of it, and a bottom camera 501 that slides and rises with the base 100. The line connecting the bottom camera 501 and the top surface light source 502 passes through the gap between two adjacent conveyor belts 203. The two ends of the line light source 900 are mounted in the arc-shaped positioning groove of the light source mounting plate 901 by adjusting screws and secured with adjusting screws. It can be understood that the bottom camera 501 and the base 100 are moved up and down by a motor, thus achieving the raising and lowering of the bottom camera 501. Loosening the adjusting screws allows the line light source 900 to slide along the arc-shaped positioning groove with the adjusting screws, while tightening the adjusting screws positions the line light source 900. See Appendix. Figure 10 The rejection station 700 includes a rejection power unit 701 rotatably mounted relative to the machine base 100. The rejection power unit 701 preferably uses a cylinder, but other linear power components can also be used. The power end of the rejection power unit 701 is rotatably mounted to one end of the rejection belt 702, and the other end of the rejection belt 702 is rotatably mounted on the machine base 100 and connected to the output end of the acceleration belt 703. It can be understood that the two ends of the rejection belt 702 at its inlet are rotatably mounted on the machine base 100 via rollers, and the outlet end of the rejection belt 702 is a free end. The side plates 208 on both sides are connected to the power end of the rejection power unit 701 via rotating shafts. When the power end of the rejection power unit 701 performs linear motion, it can drive the rejection belt 702 to rotate along one end, thereby achieving the rejection of defective products. See Appendix. Figure 9The bottle cap detection station 600 includes a bottle cap detection camera 601 and a bottle cap detection light source 602. The bottle cap detection camera 601 and the bottle cap detection light source 602 are slidably mounted on a support plate 603 via a connecting rod 604. The support plate 603 is fixedly mounted relative to the side support 210 of the belt assembly 200. The connecting rod 604 has scale lines to facilitate adjustment of the vertical position of the bottle cap detection camera 601 and the bottle cap detection light source 602. The bottle cap detection camera 601 is fixedly mounted to the bottom end of the connecting rod 604 by adjusting screws. The bottle cap detection light source 602... The bottom end of the connecting rod 604 is fastened by adjusting screws. It can be understood that the body of the bottle cap detection camera 601 is connected to the connecting rod 604 by a rotating shaft. The gap between the body of the bottle cap detection camera 601 and the connecting rod 604 is locked by screws at both ends of the rotating shaft to fix the angle of the bottle cap detection camera 601. The bracket of the bottle cap detection light source 602 is connected to the connecting rod 604 by a rotating shaft. The gap between the bracket of the bottle cap detection light source 602 and the connecting rod 604 is locked by screws at both ends of the rotating shaft to fix the angle of the bottle cap detection light source 602.

[0047] When using the equipment of this invention to inspect infusion bags, the bags to be inspected are placed into the inlet inspection station 300 by the previous process or manually. The lifting module 800 can be adjusted in advance based on the bag model, thereby adjusting the height of each inspection station. The bags pass through the inlet inspection station 300, the uphill inspection station a400, the uphill inspection station b500, the cap inspection station 600, the downhill inspection station b500, the downhill inspection station a400, and the rejection station 700. This process completes the inspection of foreign objects on the liquid edge, upper and lower surfaces, and appearance of the bags, and rejects defective products. The height of the main camera 302 at the inspection station 300 can be finely adjusted by adjusting the position of the main camera 302 using the main camera adjusting screw 3023. The tension of one end of the conveyor belt 203 of each belt conveyor unit can be adjusted by adjusting the extension plate 205. At the same time, the illumination angle of the light source at each inspection station can be adjusted. In addition, when the conveyor belt 203 needs to be disassembled, the distance between the adjusting roller and the side plate 208 is shortened by adjusting the tensioning component to loosen the conveyor belt. Then, the side support plate 201 is removed, and the conveyor belt 203 is pulled out from the side, which allows for disassembly of the conveyor belt 203. The process is convenient, quick, and saves time and effort.
