Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, and in particular to an integrated industrial protective device for hand safety monitoring, to prevent operators from accidentally entering dangerous areas during pharmaceutical production and causing safety accidents. Background Technology

[0002] Crushers and similar equipment are frequently used in the production of traditional Chinese medicine. Crushers use a motor to drive a rotating cutter head, employing shearing force to crush the raw materials. During operation, operators sometimes need to hold the herbs by hand to avoid excessive grinding caused by repeated crushing. For example, when crushing long, thin herbs like akebia stems or mulberry branches, the operator holds one end of the herb and inserts the other end into the rotating cutter head for cutting. During this process, the operator's hands are close to the cutter head and other hazardous operating areas, posing a risk of injury.

[0003] To prevent operators from accidentally entering dangerous operating areas and getting injured, some existing stamping machines, injection molding machines, and other equipment are generally equipped with light curtain sensors. These sensors use infrared light curtains to detect objects obstructing the operation and trigger the equipment's safety mechanism. However, light curtain sensors are not suitable for installation on the crushers and other equipment currently used by our company. This is because light curtain sensors cannot distinguish the type of obstructing object. While the light curtain sensor will trigger the safety mechanism when it detects an operator's hand entering the dangerous operating area, it will also trigger the safety mechanism when it detects materials such as medicinal herbs, thus preventing the equipment from operating normally.

[0004] Therefore, how to reduce production safety risks for the many different types and models of production equipment that our company currently has is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this invention is to provide an integrated industrial protective device for hand safety monitoring, which can be flexibly and conveniently installed on various types and models of existing production equipment, and can reduce production safety risks.

[0006] To achieve the above objectives, this utility model provides an integrated industrial protective device for hand safety monitoring, comprising a main body, a snake tube bracket, and a magnetic base. The main body includes a shell, a camera module, a processor, a signal output interface, and a power interface. The camera module is fixedly installed at the front end of the shell, and the processor is fixedly installed inside the shell. The signal output interface and the power interface are both installed on the shell, and the power interface supplies power to the camera module and the processor. The camera module and the signal output interface are both electrically connected to the processor. The snake tube bracket includes a snake tube and a first support body and a second support body fixedly connected to both ends of the snake tube. The first support body is connected to the main body, and the second support body is connected to the magnetic base.

[0007] In a preferred embodiment, a heat sink is mounted on the housing. The heat sink includes a heat conductor and multiple heat sinks fixed on the heat conductor. The heat conductor is located inside the housing, and the heat sinks are partially or entirely located outside the housing.

[0008] In a preferred embodiment, multiple heat sinks are arranged in parallel to each other, and a convection channel is formed between two adjacent heat sinks. By bending the coil, the direction of the convection channel between the heat sinks can be made consistent with the natural convection direction in the ambient air.

[0009] In a preferred embodiment, the housing is made of engineering plastic, and the heat sink is integrally formed with the housing.

[0010] In a preferred embodiment, the main body further includes a fill light for providing illumination to the camera module, the fill light being fixedly mounted on the housing.

[0011] In a preferred embodiment, the fill light is a ring fill light, which is coaxially arranged with the camera lens of the camera module.

[0012] In a preferred embodiment, the supplemental light is electrically connected to the processor to automatically adjust its brightness according to the lighting conditions of the operating area.

[0013] In a preferred embodiment, the first support body and the second support body are both threadedly connected to the main body and the magnetic base, respectively.

[0014] In a preferred embodiment, the signal output interface is an M12 aviation plug.

[0015] In a preferred embodiment, the coercivity of the magnetic base is not less than 600 kA / m, the remanence is not less than 0.48 T, and the load-bearing capacity of the serpentine tube is not less than 2 kg.

[0016] The difference between this invention and existing technologies lies in that the integrated industrial protective device for hand safety monitoring provided by this invention includes a main body equipped with a camera module, a processor, and a signal output interface. The main body is connected to a magnetic base via a serpentine bracket. While different types and models of production equipment vary in their working principles, dimensions, and operating areas, they all contain components that generate vibrations such as rotation, shearing, and crushing. Therefore, the beds of these machines are generally made of shock-absorbing cast iron. This invention's protective device can be easily installed at an appropriate position on the bed of these machines via the magnetic base. Furthermore, the serpentine bracket connecting the main body and the magnetic base allows the main body to be positioned at any suitable location and angle, ensuring that the camera module's lens is aimed at the hazardous operating area. Simultaneously, the camera module on the main body can collect image information from the operating area. The processor receives and analyzes the image data to determine if a person's hand is present within the monitored area. When a person's hand is detected, the processor's control signal output interface immediately outputs a corresponding electrical signal, triggering the equipment's protective action. Therefore, the integrated industrial protective device for hand safety monitoring provided by this utility model can be flexibly and conveniently installed on various types and models of existing production equipment, and can reduce production safety risks.

[0028] In the description of this application, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0030] The integrated industrial protective device for hand safety monitoring provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] like Figure 1 , Figure 2 As shown, the integrated industrial protective device for hand safety monitoring provided by this utility model includes a main body 1, a serpentine support 2, and a magnetic base 3. As... Figure 3 , Figure 4 As shown, the main body 1 includes a housing 11, a camera module 12, a processor (not shown in the figure), a signal output interface 13, and a power interface (not shown in the figure).

[0032] The outer casing 11 is preferably made of engineering plastic, giving the main body 1 good mechanical strength and electrical insulation properties. Functional areas such as a camera module 12 mounting position, a processor mounting position, and a signal output interface 13 mounting position are formed inside the outer casing 11, thereby achieving precise positioning and fixation of the device. The camera module 12 is fixedly mounted on the front end of the outer casing 11, with its camera lens located at the center of the front end of the main body 1, used to capture images of the device's operating area. The camera lens of the camera module 12 is preferably a high-definition camera. The processor is fixedly mounted inside the outer casing 11 and electrically connected to the camera module 12. It is used to analyze and process the image data captured by the camera module 12 in real time to determine the target status within the monitored area and output control signals. The processor is an embedded processor with computing power and storage capacity.

[0033] like Figure 3 , Figure 4 As shown, the signal output interface 13 is located on the rear panel of the housing 11. The signal output interface 13 is electrically connected to the processor and is used to receive control signals output by the processor and transmit these control signals to the control system of production equipment such as crushers to control the connected production equipment. The signal output interface 13 preferably uses an M12 aviation connector, which conforms to industrial standards and has a good protection level. The power interface is installed on the housing 11 and can be connected to an external power source to power the camera module 12 and the processor. The power interface preferably uses a 24V DC power interface.

[0034] The magnetic base 3 includes a cylindrical shell and a permanent magnet encapsulated inside the shell. The magnetic base 3 is used to firmly attach the entire device to the surface of a substrate made of cast iron, steel, or other materials of the production equipment. Figure 3 As shown, the serpentine tube support 2 includes a serpentine tube 21 and a first support body 22 and a second support body 23 fixedly connected to both ends of the serpentine tube 21. The serpentine tube 21 adopts a flexible metal tube structure, which has good tensile strength and corrosion resistance, and the internal metal core material can be bent arbitrarily and maintain its shape. Preferably, the coercivity of the magnetic base 3 is not less than 600 kA / m, the remanence is not less than 0.48 T, and the load-bearing capacity of the serpentine tube 21 is not less than 2 kg. The first support body 22 is connected to the main body 1, and the second support body 23 is connected to the magnetic base 3. Preferably, both the first support body 22 and the second support body 23 are connected to the main body 1 and the magnetic base 3 respectively by threads to achieve quick installation.

[0035] The integrated industrial protective device for hand safety monitoring provided in the above embodiments requires, first and foremost, to be fixed to existing equipment during use. Specifically, as shown... Figure 5As shown, first, select an appropriate position on the bed 4 of the existing production equipment such as the crusher, then attach the magnetic seat 3 to the bed 4, then bend the snake tube 21 of the snake tube support 2 so that the high-definition camera of the camera module on the main body 1 can be aimed at the dangerous operating area on the equipment, then connect the power cord to the power interface, and connect the signal output interface 13 to the production equipment with the data cable.

[0036] When the integrated industrial protection device provided by this utility model is in operation, refer to Figure 6 As shown, the system is first started. At this time, the camera module 12 continuously captures images of the operating area of ​​the device in real time. The processor receives the image data and analyzes it to determine whether there is a target (hand) of interest in the monitored operating area. The processor analyzes the captured images to determine if there is a hand in the image. An appropriate existing algorithm model can be used, such as MediaPipe Hands. MediaPipe Hands is an open-source gesture recognition model from Google, based on deep learning and traditional computer vision methods. It can detect and recognize hands and return the coordinates of 21 key points. MediaPipe Hands uses two neural networks for hand recognition: a Palm Detector model and a Hand Landmark Model model, which can detect and recognize both hands simultaneously.

[0037] When the equipment is operating normally and the operator's hand is not in the operating area, the processor does not detect the hand, and the camera module 12 continues to collect images of the operating area in real time. The processor continues to analyze and process the received image data. When the operator's hand appears in the operating area, the processor detects the hand and immediately outputs a corresponding alarm control electrical signal through the signal output interface 13, stopping the equipment. When the operator's hand leaves the operating area, the processor does not detect the hand. At this time, the processor outputs a corresponding normal operation electrical signal through the signal output interface 13, and the equipment operates normally. Simultaneously, the camera module 12 continues to collect images of the operating area in real time, and the processor continues to analyze and process the received image data. Therefore, the integrated industrial safety device provided by this utility model can effectively reduce production safety risks.

[0038] It should be noted that the integrated industrial protective device for hand safety monitoring provided by this utility model can be used not only for the safety protection of equipment in the pharmaceutical production field, but also for the safety protection of production equipment in other fields.

[0039] In a preferred embodiment of this utility model, such as Figure 4As shown, a heat sink is installed on the outer casing 11. The heat sink includes a heat conductor (not shown) and multiple heat sink fins 15 fixed on the heat conductor. The heat conductor is located inside the outer casing 11, and the heat sink fins 15 are partially or entirely located outside the outer casing 11. In this embodiment, by providing a heat sink, the heat generated by electronic devices such as the processor inside the outer casing 11 can be conducted to the outside, ensuring stable operation of the device.

[0040] Based on the above embodiments, and more preferably, the multiple heat sinks 15 are arranged parallel to each other, and a convection channel is formed between adjacent heat sinks 15. By bending the serpentine tube 21, the direction of the convection channel between the heat sinks 15 can be made consistent with the natural convection direction in the ambient air. In this embodiment, by setting the multiple heat sinks 15 to be parallel to each other to form a convection channel, they can cooperate with the serpentine tube 21. Utilizing the characteristic that the serpentine tube 21 can be bent and positioned arbitrarily, the direction of the convection channel between the heat sinks 15 can be consistent with the natural convection direction of the airflow generated by equipment such as crushers during operation. This allows the electronic equipment in the housing 11 to obtain better heat dissipation, thereby improving the operational stability of the components in the main body 1.

[0041] In this utility model, the outer shell 11 is made of engineering plastic, and the heat sink and the outer shell 11 are integrally formed by injection molding or other methods.

[0042] In some operating conditions, the lighting in the equipment's operating area is poor, causing the camera module 12 to capture images in low light. This results in an extremely low recall rate when the processor processes and analyzes the images, meaning it cannot identify clearly visible human hands. To address this issue, in a preferred embodiment, such as... Figure 4 As shown, the main body 1 also includes a fill light 14 for providing illumination to the camera module 12, and the fill light 14 is fixedly mounted on the housing 11.

[0043] Based on the above embodiments, and more preferably, the fill light 14 is a ring fill light, which is coaxially arranged with the camera lens of the camera module 12. In this embodiment, the ring fill light can provide uniform, shadow-free illumination for the camera module 12, avoiding shadows caused by unilateral light that reduce the recognition rate.

[0044] In this invention, preferably, the supplementary light 14 is electrically connected to the processor to automatically adjust its brightness according to the lighting conditions of the operating area. When the processor analyzes and processes the images of the operating area of ​​the device captured in real time by the camera module 12, and finds that the lighting in the operating area is too dim or too bright, the processor adjusts the output power of the supplementary light 14 to ensure that the camera module 12 can obtain clear images under various external lighting conditions. The supplementary light 14 preferably uses an LED light source with appropriate power and color temperature.

[0045] In summary, the integrated industrial protective device for hand safety monitoring provided by this utility model has the following beneficial effects:

[0046] 1. Easy to install and debug, suitable for various types and models of existing production equipment. This device can be quickly installed onto the metal surface of the production equipment via the magnetic base 3. The snake tube 21 can be bent and positioned arbitrarily, so the monitoring angle and position of the camera can be adjusted by bending the snake tube 21 as needed. Installation and debugging are simple and convenient, suitable for various types and models of existing production equipment.

[0047] 2. High integration, small size, and light weight. This utility model integrates core components such as the camera module 12, processor, and fill light 14 into a single housing 11, forming a main body 1. This results in a compact structure, small footprint, and ease of installation and maintenance. The housing 11 of the main body 1 can have dimensions of 80mm x 70mm x 150mm, and the main body 1 can weigh 350g.

[0048] 3. Adopting industrial standards, suitable for harsh industrial environments. This utility model uses industrial standard components such as M12 aviation plugs and engineering plastic shells, providing a high level of protection and making it suitable for harsh industrial environments.

[0049] 4. Simple maintenance. This utility model adopts an integrated design, with a simple and reliable structure, low failure rate, and low maintenance cost.

[0050] The order of the above embodiments is for ease of description only and does not represent the superiority or inferiority of the implementation methods.

[0051] Finally, it should be noted that although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
