Traditional blister packaging machines typically use a single inspection method (such as visual inspection) to reject defective products, but this method may result in missed or false detections. Furthermore, the collection and handling of defective products usually requires manual intervention, which is inefficient. Summary of the Invention

[0003] In view of the above situation and to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an automatic detection device for blister packaging machines, which solves the technical problems of existing blister packaging machines having a single detection method for medicines and low efficiency in collecting unqualified medicines.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An automatic detection device for a blister packaging machine includes: a visual rejection structure; a weight rejection structure; and a collection structure including a receiving plate, a first material frame, a second material frame, and a drive assembly. The first and second material frames are disposed at opposite ends of the receiving plate. The drive assembly is drivenly connected to the receiving plate. The waste outlets of the visual rejection structure and the weight rejection structure are arranged opposite to each other, and the receiving plate is located between the two waste outlets. The receiving plate can rotate clockwise or counterclockwise within a preset angle range under the drive assembly to pour the received defective products into the first or second material frame.

[0006] By combining visual inspection and weight inspection, the system can accurately detect substandard drugs, thereby improving product quality. At the same time, through the cooperation of the drive component and the material plate, and by using two waste bins to classify and collect substandard products, different types of substandard products can be distinguished, which is conducive to improving the efficiency of subsequent waste processing and facilitating subsequent quality analysis and problem tracing.

[0007] Optionally, the visual rejection structure includes: a first conveyor belt with a first waste outlet on one side of its output end; a visual inspection device disposed on the first conveyor belt; and a first pushing device disposed opposite to the first waste outlet, used to push the defective products detected by the visual inspection device onto the receiving plate.

[0008] Optionally, the weight rejection structure includes: a second conveyor belt, which is opposite to the conveying direction of the first conveyor belt, and has a second waste outlet on one side of its output end; a weighing sensor, which is disposed on the second conveyor belt; and a second pushing device, which is disposed opposite to the second waste outlet, for pushing the defective products detected by the weighing sensor to the receiving plate.

[0009] Optionally, the first or second pushing device includes: a telescopic mechanism disposed on one side of the conveyor belt; and a push plate connected to the movable end of the telescopic mechanism; wherein the push plate can push defective products onto the receiving plate under the drive of the telescopic mechanism.

[0010] Optionally, a third conveyor belt may also be included, wherein the first conveyor belt is connected to the second conveyor belt via the third conveyor belt.

[0011] Optionally, the driving assembly includes: a rotating rod; a connecting rod, which is perpendicular to the rotating rod, with one end connected to the rotating rod and the other end connected to the bottom of the receiving plate; and a driving motor, which is drivingly connected to the rotating rod, and the rotating rod can rotate clockwise or counterclockwise under the drive of the driving motor.

[0012] Optionally, a weighing sensor is provided on the receiving plate, and a visual inspection device is provided above the receiving plate.

[0013] Optionally, a guide plate is provided on the side of the first and second material frames away from the receiving plate. The guide plate is inclined toward the receiving plate, and there is a gap between the lower inclined end of the guide plate and the material frame.

[0014] Optionally, the receiving plate has a negative pressure chamber inside, and the upper surface of the receiving plate is provided with a plurality of adsorption holes that communicate with the negative pressure chamber. The negative pressure chamber is connected to a negative pressure generating device through a telescopic pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By combining visual inspection and weight inspection, this invention achieves accurate detection of substandard drugs, thereby improving product quality. Furthermore, compared to the traditional method of collecting waste in a single bin, this invention utilizes a drive assembly and a material plate, along with two waste bins, to classify and collect substandard products. This allows for the differentiation of different types of substandard products, improving the efficiency of subsequent waste processing and facilitating subsequent quality analysis and problem tracing.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figures 1-3 As shown in the figure, this utility model application provides an automatic detection device for a blister packaging machine, including: a visual rejection structure 1, a weight rejection structure 2, and a collection structure 3.

[0038] Both the visual waste rejection structure 1 and the weight-based waste rejection structure 2 have waste outlets at their output ends, and the two waste outlets are positioned opposite each other.

[0039] The collecting structure 3 includes a receiving plate 31, a first material frame 32, a second material frame 33, and a driving assembly 34.

[0040] A receiving plate 31 is positioned between the two waste outlets of the visual rejection structure 1 and the weight rejection structure 2, and is used to receive the non-conforming drugs rejected by the rejection structures. A first material frame 32 and a second material frame 33 are respectively positioned at both ends of the receiving plate 31; that is, the front and rear sides of the receiving plate 31 have two waste outlets, and the left and right ends have two material frames. A drive assembly 34 is positioned below the receiving plate 31 and is driven by the receiving plate 31. Under the drive of the drive assembly 34, the receiving plate 31 can rotate clockwise or counterclockwise within a preset angle range, thereby pouring the received non-conforming drugs into the first material frame 32 or the second material frame 33.

[0041] As an implementation scenario, the visual rejection structure 1 in this scenario includes: a first conveyor belt 11, a visual inspection device 12, and a first pushing device 13. The visual inspection device 12 is positioned above the first conveyor belt 11 and is used to perform visual inspection of the medicines, identifying defective products such as those with damage, foreign objects, or abnormal colors. A first waste outlet 111 is provided on one side of the output end of the first conveyor belt 11, and the first pushing device 13 is provided on the other side corresponding to the first waste outlet 111. The first pushing device 13 is used to push the defective medicines detected by the visual inspection device 12 onto the receiving plate 31. The visual inspection device 12 adopts existing technology, utilizing a camera and image processing system, and can acquire and analyze medicine images in real time.

[0042] As an implementation scenario, the weight rejection structure 2 in this scenario includes: a second conveyor belt 21, a weighing sensor, and a second pushing device 22. The weighing sensor is installed on the second conveyor belt 21 to detect the weight of the medicine and can identify defective products such as missing or extra pieces. The conveying direction of the second conveyor belt 21 is opposite to that of the first conveyor belt 11, that is, if the first conveyor belt 11 conveys from left to right, then the second conveyor belt 21 conveys from right to left. A second waste outlet 211 is provided on one side of the output end of the second conveyor belt 21. The second waste outlet 211 and the first waste outlet 111 are respectively arranged on both sides of the receiving plate 31. The second pushing device 22 is provided on the other side of the second conveyor belt 21 corresponding to the second waste outlet 211. The second pushing device 22 is used to push the defective materials detected by the weighing sensor onto the receiving plate 31.

[0043] Optionally, the first pushing device 13 includes a telescopic mechanism 131 and a push plate 132. The telescopic mechanism 131 can be an electric push rod or cylinder installed on one side of the first conveyor belt 11. The movable end of the telescopic mechanism 131 passes through the side wall of the main body of the first conveyor belt 11 and is connected to the push plate 132. The push plate 132 can push out the medicine on the surface of the first conveyor belt 11 under the drive of the telescopic mechanism 131.

[0044] Optionally, the second pushing device 22 has the same structure as the first pushing device 13, that is, the second pushing device 22 includes a telescopic mechanism and a push plate.

[0045] In one embodiment, the output end of the first conveyor belt 11 and the input end of the second conveyor belt 21 are connected by a third conveyor belt. In use, the medicine is inspected by the visual inspection device 12 on the first conveyor belt 11, and then conveyed to the second conveyor belt 21 via the third conveyor belt, where its weight is measured. In another embodiment, the output end of the second conveyor belt 21 is connected to the input end of the first conveyor belt 11 via the third conveyor belt. That is, the medicine is first weighed on the second conveyor belt 21, and then conveyed to the first conveyor belt 11 via the third conveyor belt for inspection by the visual inspection device 12.

[0046] As an implementation scenario, in this scenario, the drive assembly 34 includes a rotating rod 341, a connecting rod 342, and a drive motor 343. One end of the connecting rod 342 is connected to the bottom of the receiving plate 31, and the other end is connected to the rotating rod 341. The connecting rod 342 is set perpendicular to the rotating rod 341. One end of the rotating rod 341 is connected to the drive motor 343. The rotating rod 341 can rotate clockwise or counterclockwise under the action of the drive motor 343.

[0047] In this method of use, the conveyor belt, pushing device, vision inspection device 12, weighing sensor, and drive motor are all electrically connected to the controller for intelligent control. When the vision inspection device 12 detects a defective drug, the first pushing device 13 pushes the defective drug onto the receiving plate 31. After receiving the defective drug, the drive motor 343 drives the receiving plate 31 to rotate clockwise, pouring the defective drug into the first material frame 32. When the weighing sensor detects a defective drug, the second pushing device 22 pushes the defective drug onto the receiving plate 31. After receiving the defective drug, the drive motor 343 drives the receiving plate 31 to rotate counterclockwise, pouring the drug that is out of weight into the second material frame 33. By combining vision inspection and weight detection, accurate detection and classification collection of defective drugs are achieved, improving production efficiency.

[0048] Example 2

[0049] Based on Example 1, in this example, as Figure 4 As shown, a guide plate 35 is provided on the side of the first material frame 32 and the second material frame 33 away from the receiving plate 31. The guide plate 35 is inclinedly set on one side of the material frame via a vertical plate, with the lower inclined end of the guide plate 35 facing the receiving plate 31, and there is a gap between the lower inclined end of the guide plate 35 and the material frame. In use, when the receiving plate 31 is rotated clockwise or counterclockwise by a certain angle, such as 30°~60°, the lower inclined end of the receiving plate 31 faces the guide plate 35, causing the medicine to fall onto the guide plate 35 and then be guided into the material frame by the guide plate 35. This avoids unqualified medicines falling directly into the material frame and causing violent impact, and prevents unqualified medicines from being damaged during rejection.

[0050] Example 3

[0051] Based on Example 1, in this example, as Figure 5 As shown, the receiving plate 31 has a negative pressure chamber 311 inside. Several adsorption holes 312 communicating with the negative pressure chamber 311 are opened on the upper surface of the receiving plate 31. The negative pressure chamber 311 is connected to a negative pressure generating device via a telescopic pipe 313. In use, when the connecting rod 342 is driven to rotate, the negative pressure generating device simultaneously provides negative pressure to the negative pressure chamber 311. The negative pressure generates an adsorption force on the unqualified medicine through the adsorption holes 312. When the receiving plate 31 rotates 90° clockwise or counterclockwise, the negative pressure is disconnected, and the unqualified medicine is released. This reduces the falling height of the unqualified medicine, minimizing damage caused by falling from a height.

[0052] Example 4

[0053] Based on any of the above embodiments, in this embodiment, a weighing sensor may also be provided on the receiving plate 31, and a visual inspection device may also be provided above the receiving plate 31. In use, the added weighing sensor and visual inspection device can be used to re-check and inspect the unqualified medicines pushed out by the pushing device.

[0054] As one method of use, during use, each electrical appliance is electrically connected to the controller, which performs intelligent control. When the first pushing device 13 or the second pushing device 22 pushes the unqualified medicine onto the receiving plate 31, after the receiving plate 31 receives the unqualified medicine, the weighing sensor and visual inspection device on the receiving plate 31 re-inspect the medicine. When the appearance is unqualified, the receiving plate 31 rotates clockwise, and the unqualified medicine is poured into the first material frame 32. When the weight is unqualified, the receiving plate 31 rotates counterclockwise, and the unqualified medicine is poured into the second material frame 33.

[0055] Any aspects not described in detail in this embodiment are techniques known in the art.

[0056] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
