Description

Technical Field

[0001] The utility model relates to the technical field of on-site detection, in particular to an on-site detection device. Background Art

[0002] In-situ detection devices play a vital role in many fields such as industrial automation, warehouse management, logistics tracking and security monitoring. Their main function is to accurately determine whether an object is in a predetermined position or state, thereby ensuring smooth production processes, accurate inventory management and the implementation of safety measures. However, most of these devices rely on a single in-situ detection method or use multiple detection points based on the same physical principle to achieve their functions.

[0003] Although a single detection method has low cost and simple structure, it is susceptible to environmental interference. For example, photoelectric sensors may give false alarms due to dust or light changes, weight sensors may lose accuracy due to long-term loads, and magnetic induction sensors may fail due to external magnetic fields. False alarms or failures caused by these environmental factors will directly affect the accuracy and reliability of the system. In order to address this problem, some systems use a design that sets multiple detection points based on the same physical principle, which improves the fault tolerance of the system to a certain extent, because even if one detection point fails, other detection points can continue to work, thereby reducing the impact of a single detection point failure on the entire system. However, when the same physical factor that causes the detection point failure (such as power failure, line damage, or sensor aging) affects multiple detection points at the same time, these detection points may fail at the same time, making it impossible for the system to accurately determine the in-place status of the item.

[0029] like Figure 1 , Figure 2 , Figure 3As shown, an in-situ detection device provided in this embodiment includes: a shell 1, a detection board 11 is arranged in the shell 1, a placement groove 12 is arranged on the shell 1, the placement groove 12 is used to place objects, and the side walls of the shell 1 located on both sides of the placement groove 12 are respectively provided with infrared emitting elements 13 and infrared receiving elements 14, and the infrared emitting elements 13 and the infrared receiving elements 14 are both electrically connected to the detection board 11. When an object is placed in the placement groove 12, the sending and receiving path from the infrared emitting element 13 to the infrared receiving element 14 is blocked by the object. A mounting hole 15 is provided at the bottom of the placement groove 12, and a micro switch assembly 2 is detachably connected to the mounting hole 15, and the micro switch assembly 2 is electrically connected to the detection board 11. The micro switch assembly 2 includes a micro switch 21, and the upper end portion of the micro switch 21 extends into the placement groove 12. When an object is placed in the placement groove 12, the micro switch 21 is pressed by the bottom of the object.

[0030] Specifically, the housing 1 is made of a sturdy and durable material with dustproof and waterproof properties to protect the internal components from environmental interference. The detection board 11 has a built-in microprocessor or logic circuit and can make judgments based on, for example, a preset threshold. The infrared emitting element 13 and the infrared receiving element 14 should be of high sensitivity and low power consumption to ensure accurate detection of the presence of objects at a long distance. The micro switch 21 should be of a long life and high reliability to meet long-term and frequent use requirements. When installing the device, ensure the alignment accuracy between the infrared emitting element 13 and the infrared receiving element 14, and ensure good contact between the micro switch assembly 2 and the bottom of the object. During debugging, the dual detection mechanism is calibrated and verified to ensure its accuracy and reliability.

[0031] In this embodiment, a placement slot 12 for placing objects is provided on the housing 1. An infrared emitting element 13 and an infrared receiving element 14 are respectively installed on the side walls of the placement slot 12. Both elements are electrically connected to the detection board 11. When an object is placed in the placement slot 12, the object will block the transmission and reception path between the infrared emitting element 13 and the infrared receiving element 14. At this time, the infrared receiving element 14 cannot receive the signal sent by the infrared emitting element 13. This change can be obtained by the detection board 11. A mounting hole 15 is provided at the bottom of the placement slot 12 for installing a micro switch assembly 2. The micro switch assembly 2 is electrically connected to the detection board 11. The micro switch assembly 2 includes a micro switch 21, and its upper end portion extends into the placement slot 12. When an object is placed in the placement slot 12, the bottom of the object will press the micro switch 21, triggering the closed or open state of the micro switch 21. This pressing condition can be obtained by the detection board 11. The detection board 11 can comprehensively judge whether there is an object placed in the placement slot 12 according to the pressing condition of the micro switch 21 and / or the blocking condition of the infrared transceiver path.

[0032] This embodiment realizes dual detection of the presence of items by combining infrared cross-beam detection and physical press detection, effectively reducing the problem of false alarms or failures caused by a single detection method. Even if one of the detection mechanisms (such as infrared detection) fails due to environmental interference, the other detection mechanism (such as a micro switch) can continue to work, ensuring that the system can accurately determine the presence of items, improving the system's fault tolerance and overall reliability. The dual detection mechanism enables the device to adapt to more complex detection environments and conditions, and can meet the needs of in-situ detection in different scenarios. In addition, the micro switch assembly 2 in this embodiment is detachably connected, and the user can flexibly choose a single infrared cross-beam detection, or a dual detection combining infrared cross-beam detection and physical press detection according to the detection needs. It is flexible and convenient to use and has strong adaptability.

[0033] Alternatively, if Figure 4 As shown, the micro switch assembly 2 also includes a housing 22, the upper end of the housing 22 is provided with a downwardly extending mounting groove 221, the micro switch 21 is arranged in the mounting groove 221, the upper end portion of the micro switch 21 extends out of the mounting groove 221, the lower end of the micro switch 21 is connected to an elastic member, the lower end of the elastic member is connected to a pressure sensor, and the pressure sensor is electrically connected to the detection board 11.

[0034] Specifically, the micro switch assembly 2 includes a housing 22, and the upper end of the housing 22 is provided with a mounting groove 221 extending downward, and the mounting groove 221 provides a stable and protected installation environment for the micro switch 21. The micro switch 21 is arranged in the mounting groove 221, and its upper end part extends out of the mounting groove 221 so as to contact the object placed in the placement groove 12. The housing 22 is made of a sturdy and corrosion-resistant material to ensure its stability and reliability in long-term use. The setting of the mounting groove 221 can take into account the convenience of installation and removal of the micro switch 21, as well as the contact area and angle between the micro switch 21 and the object. The lower end of the micro switch 21 is connected to an elastic member, which is made of a material with high elasticity, fatigue resistance and corrosion resistance. Its shape and size should be optimized according to the requirements of the micro switch 21 and the pressure sensor to ensure the accuracy and stability of pressure transmission. The lower end of the elastic member is connected to a pressure sensor for detecting the pressure applied by the object to the micro switch 21. The pressure sensor should be a high-precision, low-power and easy-to-calibrate model. During the installation and debugging process, the pressure sensor is calibrated and verified to ensure the accuracy and reliability of its measurement results. When an object is placed in the placement slot 12 and contacts the micro switch 21, the pressure of the object is transmitted to the pressure sensor through the micro switch 21 and the elastic member. The pressure sensor is electrically connected to the detection board 11. When a pressure change is detected, the pressure sensor sends a corresponding electrical signal to the detection board 11. The detection board 11 can comprehensively judge whether there is an object placed in the placement slot 12 and the pressure of the object according to preset rules and thresholds. At the same time, the detection board 11 can also have the ability to communicate with a host computer or a display device so that the detection results can be displayed in real time or transmitted to relevant personnel.

[0035] In this optional embodiment, by introducing a pressure sensor, direct detection of the pressure of the object can be achieved, thereby improving the accuracy of judging the in-place status of the object. The pressure sensor can sense the slight pressure changes of the object on the micro switch 21, further enhancing the sensitivity of the detection. And by adjusting the sensitivity of the pressure sensor or setting different pressure thresholds, accurate detection of different objects can be achieved, so that the in-place detection device of this embodiment can be applicable to the detection of objects of different weights or pressure ranges. In addition to judging whether the object is in place, this embodiment can also provide additional information about the pressure or weight of the object, which can be used for further applications such as object classification, inventory management or security monitoring, simplifying the operating process, avoiding the use of additional weight detection equipment, and thus optimizing the user experience.

[0036] Alternatively, if Figure 5As shown, both sides of the upper end of the shell 22 are provided with outwardly extending blocks 222, and both sides of the lower end of the shell 1 located at the mounting hole 15 are provided with first elastic buckles 16, and the first elastic buckle 16 is provided with a limit block 161 extending toward the mounting hole 15. When the shell 22 is connected to the mounting hole 15, the lower end of the block 222 abuts against the upper end of the limit block 161.

[0037] Specifically, both sides of the upper end of the shell 22 are provided with a block 222 extending outward, and the block 222 is used as a connecting piece to cooperate with the first elastic buckle 16 on the shell 1. Both sides of the lower end of the shell 1 located at the mounting hole 15 are provided with a first elastic buckle 16, and the first elastic buckle 16 has a certain elasticity and can be deformed under the action of external force. The first elastic buckle 16 is provided with a limit block 161 extending toward the mounting hole 15, and the limit block 161 is used to abut against the lower end of the block 222, so as to limit the shell 22 from moving out of the mounting hole 15. The shape and size of the block 222 and the limit block 161 can be optimized according to the specific structure of the shell 22 and the shell 1 to ensure that the fit between them is tight and stable. At the same time, the lower end of the block 222 and the upper end of the limit block 161 can have a certain friction coefficient to increase the friction between them and prevent the shell 22 from sliding in the mounting hole 15. The first elastic buckle 16 has sufficient elasticity and resilience to ensure that the shell 22 can be deformed and restored to its original state when the shell 22 is pushed into the mounting hole 15. At the same time, the elasticity of the first elastic buckle 16 should be moderate, which can withstand the thrust of the shell 22 and will not be damaged due to excessive deformation. The shape, size and position of the mounting hole 15 can be determined according to the specific structure of the shell 22 and the housing 1 to ensure that the shell 22 can be accurately installed at the mounting hole 15. At the same time, the inner wall of the mounting hole 15 should be smooth and burr-free to avoid jamming or damage during the pushing process of the shell 22. When connecting the shell 22 and the mounting hole 15, the speed and force of pushing should be controlled to avoid damage to the block 222 or excessive deformation of the first elastic buckle 16 due to excessive speed or excessive force. At the same time, it should be ensured that after the block 222 completely passes through the limit block 161, the first elastic buckle 16 can quickly restore its original state and abut against the lower end of the block 222.

[0038] In this optional embodiment, when the housing 22 needs to be connected to the mounting hole 15, the upper end of the housing 22 is first aligned with the mounting hole 15, and then the first elastic buckle 16 is deformed to the side away from the mounting hole 15, so that the upper end of the housing 22 is inserted into the mounting hole 15 from the bottom, and then the first elastic buckle 16 is released to restore the deformation of the first elastic buckle 16, so that the limit block 161 on the first elastic buckle 16 abuts against the lower end of the block 222 on the housing 22, preventing the housing 22 from moving out of the mounting hole 15, thereby firmly connecting the housing 22 to the mounting hole 15. Through the cooperation of the block 222, the first elastic buckle 16 and the limit block 161, a firm connection of the housing 22 at the mounting hole 15 is achieved, and the housing 22 is prevented from loosening or falling off due to vibration or external force during use, and the installation process is simple and efficient. When the housing 22 needs to be removed, the first elastic buckle 16 is deformed toward the side away from the mounting hole 15 , so that the limiting block 161 is away from the clamping block 222 , and then the housing 22 is taken out from below the mounting hole 15 .

[0039] Optionally, a guiding slope is provided at one end of the limiting block 161 away from the first elastic buckle 16 , and the guiding slope is inclined toward a side away from the mounting hole 15 .

[0040] Specifically, the guide slope is inclined toward the side away from the mounting hole 15, forming a gradually expanding space. When the block 222 of the housing 22 begins to contact the stop block 161, the guide slope can guide the block 222 to smoothly enter the space above the stop block 161. The angle of the guide slope can be optimized according to the shape and size of the block 222 of the housing 22 to ensure that the block 222 can move smoothly along the slope without generating too much resistance. The length of the slope should be long enough to provide enough space and time for the block 222 to gradually adapt to the space above the stop block 161 to avoid sudden impact and deformation. Under the action of the guide slope, the first elastic buckle 16 needs to have stronger elasticity and recovery to cope with the deformation and recovery of the block 222 when it passes. The material of the buckle has good elasticity and durability to ensure that stable performance can be maintained during long-term use. Due to the existence of the guide slope, the matching accuracy of the mounting hole 15 and the housing 22 needs to be higher to ensure that the block 222 can accurately move along the guide slope and reach the space above the stop block 161.

[0041] In this optional embodiment, when the housing 22 is pushed into the mounting hole 15, the block 222 first contacts the guide bevel. Due to the inclined design of the guide bevel, the block 222 can gradually move upward along the bevel, while pushing the limit block 161 (through the elasticity of the first elastic buckle 16) to deform. When the block 222 completely passes through the guide bevel and reaches the space above the limit block 161, the first elastic buckle 16 quickly returns to its original state, and the limit block 161 abuts against the lower end of the block 222 again to complete the connection. When disassembling the housing 22, due to the presence of the bevel, the block 222 is more easily separated from the limit block 161 when moving outward, thereby reducing the difficulty of disassembly. Therefore, the guide bevel enables the block 222 of the housing 22 to pass through the limit block 161 more easily, reducing the resistance and friction during the connection process, not only speeding up the connection speed, but also reducing the heat and wear generated by friction, and extending the service life of the product. Moreover, the guiding bevel can ensure that the block 222 always moves along the correct path during the connection process, avoiding connection failure due to misalignment or jamming, improving the reliability and stability of the connection, and ensuring a firm connection of the housing 22 at the mounting hole 15.

[0042] Alternatively, if Figure 1 As shown, the placement slot 12 is a through slot, and the transmitting and receiving path from the infrared emitting element 13 to the infrared receiving element 14 is perpendicular to the extending direction of the placement slot 12 .

[0043] Specifically, the placement slot 12 is a through slot that passes through both ends of its side wall, so that an object can enter or leave from either end, making it convenient to place or take out the object. The extension direction of the placement slot 12 is perpendicular to the transceiver path between the infrared emitting element 13 and the infrared receiving element 14, ensuring that the propagation path of the infrared light is perpendicular to the extension direction of the placement slot 12, thereby improving the accuracy of detection.

[0044] In this optional embodiment, the placement slot 12 is a through slot that runs through both ends of its side walls, so that the cross-section of the shell 1 is roughly "concave" in shape, and the user can more flexibly choose the method of placing or removing objects. Moreover, the transmitting and receiving path between the infrared emitting element 13 and the infrared receiving element 14 is perpendicular to the extension direction of the placement slot 12, which helps to reduce interference of light during propagation and improve the accuracy of infrared detection, so that the system can more reliably judge the existence characteristics of the object in the placement slot 12.

[0045] Alternatively, if Figure 1 As shown, the housing 1 is also provided with a status indicator light 17 , which is electrically connected to the detection board 11 , and is used to indicate the in-place status of the object according to the judgment result of the detection board 11 .

[0046] Specifically, the status indicator light 17 is a component that can emit light of different colors or brightness, which is arranged on the housing 1 and electrically connected to the detection board 11. The status indicator light 17 can intuitively reflect the status of the item in place, that is, it emits light of a color or brightness when the item is in place, and emits another color or is off when the item is not in place. After the detection board 11 determines the status of the item in place, the status indicator light 17 can intuitively reflect the status of the item in place. The user can intuitively understand the status of the item in place by directly observing the state changes of the status indicator light 17. The visual feedback method is simple and intuitive, easy to understand and operate, and improves the user's operating convenience and experience.

[0047] In this optional embodiment, the introduction of the status indicator light 17 enables the user to directly understand the status of the item in place by visual means, without relying on other external devices or systems, thereby improving the user's operational convenience and experience. As a component of the system, the status indicator light 17 can reflect the status of the item in place in real time. When the system fails or is abnormal, the user can observe the status of the status indicator light 17 to promptly discover and take corresponding measures, thereby enhancing the reliability and stability of the system. In addition, the status indicator light 17 is simple and intuitive, easy to maintain and replace. When the indicator light fails or is damaged, the user can easily replace or repair it, reducing the maintenance cost of the system.

[0048] Alternatively, if Figure 6 As shown, the housing 1 is provided with second elastic buckles 18 on both side walls of the placement slot 12 , and the second elastic buckles 18 are used to fix the objects.

[0049] Specifically, the second elastic buckle 18 is usually made of a material with a certain elasticity, such as spring steel or plastic, which can be deformed when subjected to external force and return to its original shape after the external force disappears, so that the second elastic buckle 18 can fit objects of different sizes and shapes tightly. When the object is placed in the placement position inside the shell 1, it will contact the second elastic buckles 18 on both sides. Since the second elastic buckles 18 have a certain elasticity, they will deform appropriately according to the size and shape of the object, so as to tightly wrap the object, and ensure the stability and accuracy of the object during the detection process through an adaptive fixing method. When using it, the user only needs to put the object into the placement position and gently push or press it so that the second elastic buckle 18 fits tightly with the object. The operation is simple and convenient, and no additional tools are required.

[0050] In this optional embodiment, the adaptive fixing function of the second elastic buckle 18 can ensure that the object will not move or shake during the detection process, thereby improving the accuracy and reliability of the detection. The second elastic buckle 18 enables the in-situ detection device to be applicable to objects of different sizes and shapes, enhancing its versatility and flexibility. And because the second elastic buckle 18 has a certain elasticity, it can provide a certain buffering and protection effect on the object while fixing the object, avoiding damage caused by excessive clamping.

[0051] Alternatively, if Figure 6 As shown, avoidance grooves 19 are provided on the side walls of the placement groove 12 corresponding to the second elastic buckle 18, and the avoidance groove 19 extends to the side away from the placement groove 12, and the second elastic buckle 18 includes a connecting section 181, an elastic section 182 and a movable section 183 that are integrally connected, the connecting section 181 is connected to the bottom of the placement groove 12, the elastic section 182 protrudes to the side away from the avoidance groove 19 to form an arc structure, the movable section 183 extends to one end close to the avoidance groove 19, and the end of the movable section 183 away from the elastic section 182 extends into the avoidance groove 19.

[0052] Specifically, the avoidance groove 19 extends to the side away from the placement groove 12, providing sufficient moving space for the active section 183 of the second elastic buckle 18, ensuring that the active section 183 can move smoothly and elastically deform when subjected to the pressure of the object. The second elastic buckle 18 is formed by the connection section 181, the elastic section 182 and the active section 183 connected as one body, and is responsible for adaptively fixing the detected object. The connection section 181 is connected to the bottom of the placement groove 12 to ensure the stable installation of the second elastic buckle 18. The elastic section 182 is designed as an arc structure, which can move to one side of the avoidance groove 19 when subjected to pressure, thereby absorbing the impact force of the object. The active section 183 extends to one end close to the avoidance groove 19, and extends into the avoidance groove 19 at the end away from the elastic section 182, so that the active section 183 can move freely in the avoidance groove 19 and adjust adaptively according to the shape and size of the object. In order to further improve the stability and reliability of the system, it can be considered to optimize the material selection of the second elastic buckle 18. For example, a higher strength elastic material is used to improve the deformation ability and restoring force of the elastic section 182. At the same time, the shape and size of the avoidance groove 19 can also be fine-tuned to better match the activity requirements of the second elastic buckle 18. In addition, some auxiliary fixing mechanisms can be added to enhance the fixing effect of the system, such as adding anti-slip pads or locking devices.

[0053] In this optional embodiment, when the detected object is placed in the placement slot 12, it will contact the elastic section 182 of the second elastic buckle 18. Since the elastic section 182 is designed as an arc structure, it can move toward the avoidance slot 19 when under pressure, absorb the impact force of the object, and drive the movable section 183 to move toward the avoidance slot 19. When the object is completely placed in the placement slot 12, the elastic section 182 returns to its original state, and the elastic section 182 fits tightly to the outside of the object under the action of elastic force to fix the object. Through the avoidance slot 19 and the second elastic buckle 18, the placement slot 12 can adaptively fix objects of different shapes and sizes. In addition, the arc structure and elastic deformation ability of the second elastic buckle 18 enable it to absorb the impact force of the object, reduce the system vibration or damage caused by the impact generated when the object is placed, thereby improving the stability and reliability of the system.

[0054] Optionally, anti-slip grooves are provided on the surfaces of one side of the two elastic sections 182 that are close to each other.

[0055] Specifically, the anti-slip pattern is usually a texture composed of a series of tiny protrusions or grooves, which can increase the friction between the second elastic buckle 18 and the object, thereby preventing the object from sliding or falling off during the detection process. When the object to be detected is placed in the placement position and fixed by the second elastic buckle 18, the anti-slip pattern can increase the contact area and friction between the second elastic buckle 18 and the object, thereby preventing the object from sliding or falling off due to external forces (such as vibration, impact, etc.) during the detection process, ensuring the stability and accuracy of the object during the detection process. In addition, the anti-slip pattern can adapt to the objects to be detected of different materials. Whether it is metal, plastic or other materials, the anti-slip pattern can provide sufficient friction to ensure that the object is firmly fixed in the placement position.

[0056] In this optional embodiment, by adding anti-skid patterns, the fixing effect of the second elastic buckle 18 on the detected object is further enhanced, preventing the object from sliding or falling off during the detection process, thereby improving the accuracy and reliability of the detection. The anti-skid patterns can also improve the safety of the device. In some occasions where objects need to be strictly fixed (such as quality inspection on a production line), the anti-skid patterns can ensure that the objects will not fall off or be damaged due to external forces, thereby avoiding potential safety hazards. The anti-skid patterns make users feel more assured and convenient when using the device. They do not need to worry about the objects falling off or being damaged due to unstable fixation, thereby improving user satisfaction and trust.

[0057] Optionally, transparent protective covers are respectively provided on the outer sides of the infrared emitting element 13 and the infrared receiving element 14 , and the transparent protective covers are fixedly connected to the housing 1 .

[0058] Specifically, as a protective layer for the infrared emitting element 13 and the infrared receiving element 14, the transparent protective cover plays a vital role. It can be made of highly transparent, wear-resistant, and corrosion-resistant materials, such as glass, transparent plastic, etc. These materials can ensure smooth transmission of infrared signals while providing sufficient protection. The design shape and size of the transparent protective cover match the infrared emitting element 13 and the infrared receiving element 14 to ensure that it fits tightly and completely covers these elements.

[0059] In this optional embodiment, the transparent protective cover can prevent dust, moisture, dirt and other external factors from contaminating or damaging the infrared emitting element 13 and the infrared receiving element 14, thereby extending the service life of the elements and improving the reliability and stability of the entire device. In addition, the transparent protective cover provides a certain mechanical protection for the infrared emitting element 13 and the infrared receiving element 14, helping to prevent external objects from directly hitting or damaging the elements, thereby improving the durability of the entire device.

[0060] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
