Abstract
Description
Technical fields:
[0001] This utility model relates to the field of manufacturing technology of auxiliary equipment for packaging finished immunochromatographic test strip products. Specifically, it is a product quantitative packaging device with reasonable structure, reliable operation, and the ability to quantitatively adjust the packaging quantity according to needs. Background technology:
[0002] Immunochromatographic assays utilize antigen-antibody immunological reactions and chromatographic reactions, presented as dry strip test strips, to achieve rapid and accurate colorimetric detection of analytes. In the development of clinical medical testing technology, it is now possible to detect over 100 antigens, including various hormones, cancer antigens, viruses, bacteria, antibodies, synthetic antigens, and drug abuse markers. Immunochromatographic test strips are strip-shaped, small in size, and lightweight. During storage and transportation, they are packaged in test strip cards or sealed bags. For ease of sale, test strips are packaged in pre-defined quantities. Currently, the packaging process requires manual counting, which can lead to errors and omissions, and is costly and inefficient. Summary of the Invention:
[0003] This invention addresses the shortcomings and deficiencies of existing technologies by proposing a quantitative packaging device for immunochromatographic test strips that can significantly improve the accuracy and efficiency of packaging at the factory.
[0004] This utility model achieves its purpose through the following measures:
[0005] A product quantitative packaging device is characterized by comprising a hopper, a product gripping mechanism, a product conveying mechanism, and a counting mechanism. The hopper has a material inlet, the product gripping mechanism is arranged opposite to the material inlet, and the hopper and the product gripping mechanism are arranged above the product conveying mechanism. The product gripping mechanism is provided with a negative pressure material suction cup and a linear piston cylinder for driving the negative pressure material suction cup to approach / move away from the material inlet of the hopper. After the negative pressure material suction cup is driven by the linear piston cylinder to suck up the material at the material inlet, it is driven by the linear piston cylinder to leave the material inlet and release the negative pressure, so as to put the gripped material onto the product conveying mechanism.
[0006] The counting mechanism of this utility model includes a PLC controller, a first position sensor for detecting the movement of the product gripping mechanism, and an alarm. The PLC controller is connected to the first position sensor and the alarm. The first position sensor is located on the side of the product gripping mechanism and is installed via a support plate. The first position sensor is used to collect position data at the closest distance between the negative pressure material suction cup and the material inlet of the hopper. The first position sensor is implemented using an infrared sensor or a photoelectric switch. Furthermore, a verification position sensor is also provided for verifying the quantitative counting of products. The verification position sensor is connected to the PLC controller and is located on the side of the product conveying mechanism to detect the number of products currently conveyed on the conveying mechanism. Furthermore, at least two verification position sensors can be provided.
[0007] The hopper and the product gripping mechanism of this invention are arranged in a straight line and have an angle with the horizontal direction. The vertical position of the hopper is higher than the vertical position of the product gripping mechanism. The negative pressure suction cup in the product gripping mechanism reciprocates along the straight line between the hopper and the product gripping mechanism under the drive of the linear piston cylinder.
[0008] The product conveying mechanism of this utility model adopts a conveyor belt type conveying mechanism, including a frame, a conveyor belt, a conveyor drive motor, a drive roller, and a driven roller. The conveyor belt is horizontally arranged below the hopper and the product gripping mechanism. In the product conveying mechanism, the conveyor belt transports the material from the end close to the product gripping mechanism to the end far away from the product gripping mechanism.
[0009] The present invention further describes that the bottom plate of the hopper is inclined and slopes down from the rear end of the hopper to the feeding port at the front end of the hopper. The hopper is provided with a material sorting frame, which is installed above the feeding port. The material sorting frame is strip-shaped and its rear end curves outward to sort the materials sent out of the feeding port in the hopper. Furthermore, the hopper is also provided with a material pushing component that pushes the material to be taken towards the feeding port. The material pushing component includes a push plate and a push plate guide component. The push plate guide component is arranged along the material pushing direction. Furthermore, the push plate guide component adopts a guide bar and a sliding sleeve. The sliding sleeve is connected to the push plate and sleeved on the guide bar. The guide bar is arranged along the material pushing direction in the hopper. Furthermore, in order to ensure stable pushing of the material, two parallel guide bars are provided and located on both sides of the hopper. The sliding sleeves on the guide bars are fixedly connected to the push plate.
[0010] This utility model product is packaged in a flexible packaging bag. The test strip itself is small and lightweight, resulting in a single, individually packaged product that is sheet-like and enclosed in a flexible packaging bag. Under the suction of the negative pressure suction cup, it can be pulled out along the feeding port of the hopper. Afterwards, closing the negative pressure at the rear end of the suction cup allows it to detach from the suction cup as it moves away from the feeding port, falling onto the conveyor belt of the material conveying mechanism. The material conveying mechanism then transports it to a packaging box located at the end of the conveyor belt. During the material's descent, in order to… To prevent the material from migrating backward with the negative pressure suction cup or getting stuck in a certain position due to deformation and stacking of the product packaging bag, a guide plate is provided above the material conveying mechanism corresponding to the material landing area. The guide plate is connected to the frame via a bracket. The guide plate has a smooth surface. Furthermore, the guide plate has a smooth surface that slopes downward along the material conveying direction. In addition, the guide plate has a smooth surface that slopes downward in an arc shape along the material conveying direction to buffer the impact force when the material falls after detaching from the negative pressure suction cup, so that it lands smoothly on the conveyor belt.
[0011] In operation, this invention uses a PLC controller in the counting mechanism to set the number of materials to be grabbed according to the packaging specifications. The first position sensor and the verification position sensor monitor the number of times materials are grabbed and the number of materials conveyed, thereby ensuring that products are picked up and packaged in a quantitative manner. When abnormal conditions such as incorrect picking or omission occur, the PLC controller outputs an alarm signal through an alarm device. The alarm device prompts the operator to troubleshoot the fault in time through indicator lights and a buzzer.
[0012] Compared with the prior art, this utility model can complete continuous, efficient and accurate quantitative sorting and packaging, and has significant advantages such as reasonable structure, simple operation and accuracy. Attached image description:

[0019] The counting mechanism of this utility model includes a PLC controller 8, a first position sensor 6 for detecting the action of the product gripping mechanism, and an alarm 9. The PLC controller 8 is connected to the first position sensor 6 and the alarm 9. The first position sensor 6 is located on the side of the product gripping mechanism and is installed via a support plate.

Furthermore, a verification position sensor 7 is provided for verifying the quantitative counting of products. The verification position sensor 7 is connected to the PLC controller and is located on the side of the product conveying mechanism to detect the number of products currently conveyed on the conveying mechanism. Furthermore, at least two verification position sensors 7 can be provided.
[0020] The hopper 1 of this utility model is arranged in a straight line with the product gripping mechanism and has an angle with the horizontal direction. The vertical position of the hopper 1 is higher than the vertical position of the product gripping mechanism. The negative pressure suction cup 4 in the product gripping mechanism reciprocates along the straight line between the hopper 1 and the product gripping mechanism under the drive of the linear piston cylinder 5.
[0021] The product conveying mechanism of this utility model adopts a conveyor belt type conveying mechanism, including a frame 10, a conveyor belt 11, a conveyor drive motor, a drive roller, and a driven roller. The conveyor belt is horizontally arranged below the hopper and the product gripping mechanism. In the product conveying mechanism, the conveyor belt transports the material from the end close to the product gripping mechanism to the end far away from the product gripping mechanism.
[0022] The present invention further describes that the bottom plate of the hopper 1 is inclined and slopes down along the rear end of the hopper 1 to the feeding port 2 at the front end of the hopper. The hopper 1 is provided with a material sorting frame 12, which is installed above the feeding port 2. The material sorting frame 12 is strip-shaped and its rear end curves outward to sort the materials sent out of the feeding port in the hopper 1. Furthermore, the hopper 1 is also provided with a material pushing component that pushes the material to be taken towards the feeding port. The material pushing component includes a push plate 13 and a push plate guide component 14. The push plate guide component is set along the material pushing direction. Furthermore, the push plate guide component adopts a guide bar and a sliding sleeve. The sliding sleeve is connected to the push plate and sleeved on the guide bar. The guide bar is set along the material pushing direction in the hopper. Furthermore, in order to ensure stable pushing of the material, two parallel guide bars are provided and located on both sides of the hopper. The sliding sleeves on the guide bars are fixedly connected to the push plate.
[0023] This utility model product is packaged in a flexible packaging bag. The test strip itself is small and lightweight, resulting in a single, individually packaged product that is sheet-like and enclosed in a flexible packaging bag. Under the suction of the negative pressure suction cup, it can be pulled out along the feeding port 2 of the hopper 1. Afterwards, the negative pressure at the rear end of the negative pressure suction cup is turned off, allowing the product to detach from the suction cup as it moves away from the feeding port and fall onto the conveyor belt of the material conveying mechanism. The material conveying mechanism then transports the product to a packaging box located at the end of the conveyor belt. During the material's descent, measures are taken to prevent... The falling position may be affected by the negative pressure suction cup moving towards the rear or by the product packaging bag being deformed and stacked, causing it to get stuck at a certain position. A guide plate 15 is provided above the material conveying mechanism corresponding to the material falling area. The guide plate 15 is connected to the frame via a bracket. The guide plate 15 has a smooth surface. Furthermore, the guide plate has a smooth surface that slopes downward along the material conveying direction. In addition, the guide plate 15 has a smooth surface that slopes downward in an arc shape along the material conveying direction to buffer the impact force when the material falls after leaving the negative pressure suction cup, so that it falls smoothly onto the conveyor belt.

In this example, the verification position sensor 7 is set on the sorting beam 16, and a downward-sloping unloading plate is provided at the end of the product conveying mechanism. A second composite position sensor 7 is provided at the feeding end of the unloading plate for verifying the quantity of material that finally enters the packaging box.
[0027] In operation, this invention uses a PLC controller in the counting mechanism to set the number of materials to be grabbed according to the packaging specifications. The first position sensor and the verification position sensor monitor the number of times materials are grabbed and the number of materials conveyed, thereby ensuring that products are picked up and packaged in a quantitative manner. When abnormal conditions such as incorrect picking or omission occur, the PLC controller outputs an alarm signal through an alarm device. The alarm device prompts the operator to troubleshoot the fault in time through indicator lights and a buzzer.
