Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to a testing structure and an air conditioner copper pipe testing mechanism. Background Technology

[0002] In existing technologies, copper tube processing in the air conditioning manufacturing industry, especially the bending process, typically relies on an automated feeding and cutting system to improve production efficiency and accuracy. This system mainly includes a feeding assembly for positioning and horizontal movement of the copper tube, and a cutting assembly responsible for cutting the copper tube at a designated location. In normal operation, the feeding assembly delivers the copper tube to the cutting position, where the pre-cutting clamp is released to allow the copper tube to be accurately positioned, and the cutting assembly then performs the cutting operation.

[0003] However, after long-term operation, the pre-cutting clamp may malfunction, that is, it may still clamp the copper tube when it should be loosened, causing the copper tube to bend during feeding and block the equipment. This situation is often not easy to detect in time, leading to production interruption and affecting production efficiency.

[0004] However, with long-term operation of the equipment, aging or wear of mechanical parts is inevitable, the most prominent issue being the failure of the pre-cutting clamp. As the last positioning point before copper tube cutting, the pre-cutting clamp's function is to release the copper tube momentarily before cutting, ensuring cutting accuracy. If the pre-cutting clamp fails to respond when it should release, and instead continues to incorrectly clamp the copper tube, it may cause unexpected bending of the copper tube during subsequent feeding. Bending of the copper tube not only immediately causes blockage of the conveying channel, but also, due to the hidden and sudden nature of this malfunction, it is often not detected and handled in a timely manner, thus triggering equipment shutdown, seriously affecting production progress and efficiency, and even posing a potential threat to the long-term stable operation of the equipment. Utility Model Content

[0005] The main purpose of this utility model is to provide a detection structure and an air conditioner copper pipe detection mechanism to solve the problem that copper pipe bending cannot be detected in time in the prior art, which leads to equipment downtime and reduced production efficiency.

[0006] To achieve the above objectives, according to one aspect of the present invention, a detection structure is provided. The detection structure is installed on a mounting base and located in front of a cutting assembly. A fixed space is formed between the cutting structure of the cutting assembly and the detection structure. A feeding structure is also provided on the mounting base to transport the target workpiece into the fixed space. The detection structure includes:

[0007] The detection element has a detection state to detect whether a target workpiece in a fixed space is bent. When the target workpiece in the fixed space is bent, the target workpiece is in at least partial contact with the detection element, so that the detection element switches from the detection state to the non-detection state.

[0008] An electrical connector, one end of which is connected to the detection element and the other end of which is connected to the power source, so that the detection element is in a charging state through the electrical connector;

[0009] An alarm component is connected to the detection element to trigger an alarm when the detection element is in a non-detection state.

[0010] Furthermore, the detection structure includes:

[0011] The detection body has a through-hole for the target workpiece to pass through, and the through-hole is connected to a fixed space.

[0012] When the target workpiece is bent, at least a portion of the target workpiece outside the fixed space comes into contact with the test piece.

[0013] Furthermore, when the detection component is in a non-detection state, it is in contact with the target workpiece and is in a short-circuit state;

[0014] Both the test piece and the target workpiece are made of copper.

[0015] Furthermore, the detection structure also includes:

[0016] A color recognition component is installed on the mounting base to detect the color of the target workpiece during the process of the feeding structure transporting the target workpiece to a fixed space.

[0017] Furthermore, the number of color recognition components is at least two, with one color recognition component located outside the fixed space and the other color recognition component located inside the fixed space.

[0018] Furthermore, the detection structure also includes:

[0019] Fixed components are installed on the mounting base.

[0020] A connecting component is disposed on a fixed component. The connecting component includes a first connecting portion and a second connecting portion, at least one of which is located within a fixed space for fixing a color recognition component.

[0021] Furthermore, the fixing components include:

[0022] At least two first fixing parts, and each of the at least two first fixing parts is provided with a first fixing position;

[0023] A second fixing part is disposed between at least two first fixing parts, and the second fixing part is used to install the test piece;

[0024] The mounting base is provided with a first mounting position at a position corresponding to the first fixing position. The fixing component also includes a first locking component, which is provided corresponding to the first fixing position. The first locking component can be inserted into the first fixing position so as to fix the fixing component to the mounting base through the first locking component.

[0025] Furthermore, the fixing components also include:

[0026] The detection fastener is set on the second fixing part of the fixing component. The detection fastener is provided with at least one detection fixing position. The second fixing part is provided with a second mounting position, and the second mounting position is provided in correspondence with the detection fixing position.

[0027] The fixing component further includes a second locking component, which is correspondingly disposed with at least one detection fixing position. The second locking component can be interleaved on the corresponding detection fixing position so as to fix the detection fixing member on the second fixing part by means of the second locking component.

[0028] Furthermore, the testing of the fasteners includes:

[0029] The first fixing member is disposed on the second fixing part;

[0030] The second fixing member has a fixing surface that forms a fixed angle with the fixing surface of the first fixing member, and the detection element is disposed on the second fixing member.

[0031] According to another aspect of the present invention, an air conditioner copper pipe detection mechanism is provided, including a detection structure, which is the detection structure described above.

[0032] By introducing a detection component, this device can monitor the status of the copper tube within a fixed space in real time during the copper tube feeding process. Once an unexpected bend is detected in the copper tube, a signal change is immediately triggered on the electrical connector, causing the detection component to switch from a charging state to a non-detection state. This change in state will cause the alarm component to issue a warning signal, promptly alerting the operator to the abnormal condition of the equipment and avoiding the risk of equipment blockage and downtime caused by copper tube bending.

[0033] This detection structure, along with key components such as the feeding structure and tube cutting assembly, implements an automated detection, early warning, and response mechanism. During copper tube processing, once the detection structure senses an abnormal state, it automatically stops feeding to prevent further damage and initiates emergency procedures, minimizing the impact on production efficiency. It also reduces the workload of operators and improves the overall automation level of the production line.

[0034] Traditional copper tube processing equipment often takes a long time to detect copper tube bending problems caused by pre-cutting clamp malfunctions, by which time the equipment may have already suffered damage. This invention, however, provides early warning, allowing for timely intervention in the initial stages of copper tube bending, effectively preventing further damage to the equipment. This reduces maintenance costs and repair cycles, ensuring the continuous and stable operation of the production line. Attached Figure Description

Detailed Implementation

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] In existing technologies, copper tube processing in the air conditioning manufacturing industry, especially the bending process, typically relies on an automated feeding and cutting system to improve production efficiency and accuracy. This system mainly includes a feeding assembly for positioning and horizontal movement of the copper tube, and a cutting assembly responsible for cutting the copper tube at a designated location. In normal operation, the feeding assembly delivers the copper tube to the cutting position, where the pre-cutting clamp is released to allow the copper tube to be accurately positioned, and the cutting assembly then performs the cutting operation.

[0042] However, after long-term operation, the pre-cutting clamp may malfunction, that is, it may still clamp the copper tube when it should be loosened, causing the copper tube to bend during feeding and block the equipment. This situation is often not easy to detect in time, leading to production interruption and affecting production efficiency.

[0043] However, with long-term operation of the equipment, aging or wear of mechanical parts is inevitable, the most prominent issue being the failure of the pre-cutting clamp. As the last positioning point before copper tube cutting, the pre-cutting clamp's function is to release the copper tube momentarily before cutting, ensuring cutting accuracy. If the pre-cutting clamp fails to respond when it should release, and instead continues to incorrectly clamp the copper tube, it may cause unexpected bending of the copper tube during subsequent feeding. Bending of the copper tube not only immediately causes blockage of the conveying channel, but also, due to the hidden and sudden nature of this malfunction, it is often not detected and handled in a timely manner, thus triggering equipment shutdown, seriously affecting production progress and efficiency, and even posing a potential threat to the long-term stable operation of the equipment.

[0044] The main purpose of this utility model is to provide a detection structure and an air conditioner copper pipe detection mechanism to solve the problem that copper pipe bending cannot be detected in time in the prior art, which leads to equipment downtime and reduced production efficiency.

[0045] To address the above problems, this application first provides a detection structure, such as... Figures 1 to 2 As shown, the detection structure 1 is installed on the mounting base 2 and located in front of the cutting assembly. A fixed space is formed between the cutting structure of the cutting assembly and the detection structure 1. The mounting base 2 is also equipped with a feeding structure 3 to transport the target workpiece into the fixed space. The detection structure 1 includes:

[0046] The detection element 11 has a detection state to detect whether the target workpiece in the fixed space is bent. When the target workpiece in the fixed space is bent, the target workpiece is in at least partial contact with the detection element 11, so that the detection element 11 switches from the detection state to the non-detection state.

[0047] An electrical connector is provided, with one end connected to the detection element 11 and the other end connected to a power source, so that the detection element 11 is in a charging state through the electrical connector.

[0048] An alarm component is connected to the detection element 11 to trigger an alarm when the detection element 11 is in a non-detection state. The alarm component is electrically or signal-connected to the detection element 11.

[0049] By introducing the detection element 11, this mechanism can monitor the status of the copper tube in the fixed space in real time during the copper tube feeding process. Once an unexpected bend in the copper tube is detected, a signal change on the electrical connector is immediately triggered, causing the detection element 11 to switch from the charging state to the non-detection state. This change in state will cause the alarm component to issue a warning signal, promptly reminding the operator to pay attention to the abnormal condition of the equipment and avoiding the risk of equipment blockage and downtime caused by copper tube bending.

[0050] This detection structure, along with key components such as the feeding structure 3 and the tube cutting assembly, implements an automated detection, early warning, and response mechanism. During copper tube processing, once the detection structure 1 detects an abnormal state, it can automatically stop feeding to prevent further damage and initiate emergency procedures to reduce the impact on production efficiency. It also reduces the workload of operators and improves the overall automation level of the production line.

[0051] Traditional copper tube processing equipment often takes a long time to detect copper tube bending problems caused by pre-cutting clamp malfunctions, by which time the equipment may have already suffered damage. This invention, however, provides early warning, allowing for timely intervention in the initial stages of copper tube bending, effectively preventing further damage to the equipment. This reduces maintenance costs and repair cycles, ensuring the continuous and stable operation of the production line.

[0052] Furthermore, detection structure 1 includes:

[0053] The detection body 111 has a through-hole for the target workpiece to pass through, and the through-hole is connected to the fixed space.

[0054] When the target workpiece is bent, the target workpiece outside the fixed space comes into at least partial contact with the detection element 11, wherein the through position is a through hole.

[0055] By establishing a through-hole on the detection body 111, the target workpiece can pass smoothly during normal feeding. When the target workpiece, i.e., the copper tube, bends, the bent portion will contact a part of the structure of the detection element 11, triggering a change in the detection state. This design makes bending detection more accurate, reduces the false alarm rate, and also avoids interference during normal processing, thus improving the reliability and accuracy of the detection.

[0056] The through-hole design ensures that the contact between the detection body 111 and the target workpiece is limited to when the copper tube is bent. This means that during normal operation, the copper tube can pass directly through the through hole into the fixed space, and the detection structure will not come into direct contact with the copper tube, thus avoiding possible damage to the surface of the copper tube and maintaining product quality.

[0057] When the detection component 11 detects an abnormal bend in the target workpiece, it immediately changes its detection status and triggers an alarm mechanism. Operators can quickly locate the problem area and isolate the abnormal copper tube to prevent it from entering the subsequent process, thus reducing interference and unnecessary waste of resources in subsequent processing stages.

[0058] Furthermore, when the detection element 11 is in a non-detection state, the detection element 11 is in contact with the target workpiece, and the detection element 11 is in a short-circuit state;

[0059] Both the test piece 11 and the target workpiece are made of copper.

[0060] In this embodiment, if the copper tube is not bent, it will not come into contact with the detection element 11, and the detection element 11 will always be in an energized state. If the copper tube is bent, at least a part of the copper tube will come into contact with the detection element 11, thereby causing the detection element 11 to change from an energized state to a short-circuit state. In this way, it is possible to accurately determine whether the copper tube is bent, and thus accurately determine whether the pre-cutting clamp is blocked.

[0061] Because copper has excellent electrical conductivity, when the detection element 11 comes into contact with the target workpiece (the bent copper tube), a short circuit is immediately formed. This change in state can be quickly captured by the detection system without any additional time delay. This instantaneous signal feedback greatly accelerates the detection speed of abnormal situations, ensuring timely anomaly management on the production line.

[0062] A short circuit, as a clear electrical state change, ensures the high sensitivity of the detection system. Even a slight bend in the copper tube or a small contact area can reliably trigger a short circuit in the detection element 11, ensuring that all abnormalities can be effectively identified and improving the comprehensiveness and accuracy of the detection.

[0063] Since the detection component 11 and the target workpiece are made of the same material, the contact resistance between them is low. This ensures that the transmission of electrical signals is stable and reliable when a short circuit is formed, reduces electrical instability caused by material differences, and makes the acquisition of detection signals more stable.

[0064] By utilizing the characteristic that a short circuit can be formed when two copper components of the same material come into contact, the design of the detection circuit can be simplified, avoiding the use of complex sensing elements and signal processing units.

[0065] Furthermore, detection structure 1 also includes:

[0066] Color recognition component 12 is mounted on mounting base 2 to detect the color of target workpiece during the process of feeding structure 3 conveying target workpiece to fixed space.

[0067] This application sets up a color recognition component 12, which can identify whether the color of the target workpiece is consistent with the color of the detection component 11. When the color of the target workpiece is consistent with the color of the detection component 11, the following process will be performed. When the color of the target workpiece is inconsistent with the color of the detection component 11, the target workpiece with inconsistent color will be removed.

[0068] The color recognition component 12 can monitor the color of the target workpiece in real time, ensuring that only workpieces whose color matches that of the inspection component 11 can continue to be processed. This precise color matching mechanism effectively avoids further processing of defective products (such as "black tubes"), significantly improving the accuracy and efficiency of product quality control.

[0069] When the color of the target workpiece does not match the color of the inspection piece 11, the color recognition component 12 will immediately send a signal, instructing a robot or other removal device to remove the workpiece with the mismatched color. This setup reduces reliance on human labor, avoids production errors caused by human misjudgment, and improves the automated screening capability of the production line.

[0070] Working in conjunction with the feeding structure 3, the color recognition component 12 ensures that only qualified workpieces enter the fixed space for subsequent processing, avoiding production interruptions caused by defective products entering the system. This process optimization maintains production continuity, avoids unnecessary downtime, and improves production efficiency.

[0071] Furthermore, the number of color recognition components 12 is at least two, with one color recognition component 12 disposed outside the fixed space and the other color recognition component 12 disposed inside the fixed space.

[0072] Specifically, the number of color recognition components 12 is set to two to ensure the accuracy of detection, because in actual use, the color recognition components 12 may be damaged. When one color recognition component 12 is damaged, the other color recognition component 12 can continue to perform detection.

[0073] The configuration of two color recognition components 12 is equivalent to establishing a double detection defense. First, the color recognition component outside the fixed space can perform preliminary color recognition on the target workpiece. Once an abnormal color is detected, it can immediately prevent the unqualified workpiece from entering the next processing step. Second, the internal color recognition component 12 performs a secondary confirmation after the workpiece enters the fixed space, ensuring that no one is missed. This double protection improves the accuracy and reliability of the detection.

[0074] In practical applications, any detection equipment may face the risk of malfunction or performance degradation. By setting up two color recognition components 12, even if one fails, the other can continue to work normally, maintaining the continuity and stability of color detection and ensuring uninterrupted judgment of workpiece status on the production line.

[0075] Furthermore, detection structure 1 also includes:

[0076] Fixing component 13 is mounted on mounting base 2;

[0077] A connecting component 14 is disposed on a fixing component 13. The connecting component 14 includes a first connecting portion 141 and a second connecting portion 142. At least one of the first connecting portion 141 and the second connecting portion 142 is located in a fixed space for fixing the color recognition component 12.

[0078] Specifically, the bottom of the fixing component 13 is provided with a mounting groove, the shape of which is consistent with the shape on the mounting base 2, and the groove opening size is larger than the groove bottom size, which can ensure the stability of the mounting groove installation. The connecting component 14 is Z-shaped and includes a first connecting part 141 and a second connecting part 142. The first connecting part 141 and the second connecting part 142 are arranged in parallel. A third connecting part is also provided between the first connecting part 141 and the second connecting part 142. The extension direction of the third connecting part is perpendicular to both the first connecting part 141 and the second connecting part 142. Furthermore, the extension directions of the first connecting part 141 and the second connecting part 142 are opposite. The first connecting part 141 is located in a fixed space and is used to fix the color recognition component. In this embodiment, the color recognition component 12 is specifically a photoelectric sensor, which can detect the appearance / color of the target component and accurately capture subtle color differences. By using the color recognition component 12, the color of the target component can be accurately identified.

[0079] The mounting groove design at the bottom of the fixing component 13 has a groove opening size larger than the groove bottom size, which ensures that the fixing component 13 is firmly installed on the mounting base 2. Even in the vibration environment of high-speed operation of the production line, the stability of the detection structure can be maintained, avoiding detection deviations caused by loose installation, and improving the reliability and accuracy of detection.

[0080] The Z-shaped structure of the connecting component 14, through its layout including the first connecting part 141, the second connecting part 142, and the third connecting part, allows the color recognition component 12 to be flexibly positioned inside and outside a fixed space. This design allows the color recognition component to adjust its position according to detection needs, achieving optimal detection angle and accuracy whether for initial color screening or secondary confirmation, thus enhancing the adaptability of the detection structure to different production scenarios.

[0081] The first connecting part 141 extends deep into the fixed space, ensuring that the color recognition component 12 can identify the color of the target workpiece at close range with high clarity. This design avoids color recognition errors that may occur during long-distance detection, especially in low light or obstructed conditions, thus improving detection accuracy.

[0082] The design of the fixed component 13 and the connecting component 14 facilitates disassembly and reassembly. When the color recognition component 12 needs maintenance or replacement, the operator can easily remove the component from the first connecting part 141 or the second connecting part 142 for processing without disassembling the entire device, which greatly simplifies the maintenance process and shortens downtime.

[0083] Furthermore, the fixing component 13 includes:

[0084] At least two first fixing parts 131, and each of the at least two first fixing parts 131 is provided with a first fixing position 132;

[0085] The second fixing part 133 is disposed between at least two first fixing parts 131, and the second fixing part 133 is used to install the detection piece 11;

[0086] The mounting base 2 is provided with a first mounting position corresponding to the first fixing position 132. The fixing component 13 also includes a first locking component, which is provided corresponding to the first fixing position 132. The first locking component can be inserted into the first fixing position 132 so as to fix the fixing component 13 to the mounting base 2 through the first locking component.

[0087] Specifically, the fixing component 13 is U-shaped and is arranged perpendicular to the arrangement direction of the two first fixing parts 131. The height of the second fixing part 133 is less than the height of the first fixing part 131. The detection component 11 is disposed on the second fixing part 133. The first mounting position and the first fixing position 132 are both bolt holes, and the first locking component is a bolt.

[0088] The cooperation of the first locking component (e.g., a bolt) with the first fixing position 132 and the first mounting position ensures a firm connection between the fixing component 13 and the mounting base 2. This stable fixing method avoids component displacement caused by vibration or external force, maintains the detection accuracy of the detection component 11 and the color recognition component 12, and enhances the stability of the overall detection system.

[0089] The design of at least two first fixing parts 131 not only provides multiple mounting points but also allows the color recognition component 12 to be flexibly installed in different positions according to production requirements. At the same time, this design also supports adjusting the relative positions of the components when needed to optimize detection results and adapt to different stages of the production line or changes in working conditions.

[0090] The second fixing part 133 is used to mount the detection component 11. Its height is designed to be lower than that of the first fixing part 131, allowing the detection component 11 to be closer to the target workpiece, thus achieving high-precision contact detection. This precise positioning helps to improve the sensitivity and accuracy of the detection, ensuring immediate feedback on the workpiece status.

[0091] Furthermore, the fixing component 13 also includes:

[0092] The detection fastener 134 is disposed on the second fixing part 133 of the fixing component 13. The detection fastener 134 is provided with at least one detection fixing position, and the second fixing part 133 is provided with a second mounting position, which is provided in correspondence with the detection fixing position.

[0093] The fixing component 13 further includes a second locking component, which is correspondingly disposed with at least one detection fixing position. The second locking component can be interleaved on the detection fixing position corresponding to it, so as to fix the detection fixing member 134 on the second fixing part by means of the second locking component.

[0094] Specifically, the detection fixture 134 is a detection table, and the detection fixture 11 and the detection fixture 134 are fixed together by bolts. The detection fixing position and the second mounting position are both bolt holes, and the second locking component is a locking bolt.

[0095] The detection fixture 134 (such as a detection table) is connected to the detection piece 11 through at least one detection fixing position, ensuring the precise fixation of the detection piece 11. This design enables the detection piece 11 to be stably positioned in the ideal detection position, improving the accuracy and consistency of the detection, especially in situations requiring precise contact or position detection of the workpiece.

[0096] The second fixing part 133 is connected to the second locking component (e.g., locking bolt) between the second fixing part 133 and the detection fixing part 134, forming a stable double-layer fixing structure, which further enhances the stability of the detection part 11 on the fixing part 13. Even under the high-intensity operation of the production line, the detection part 11 can be firmly installed, avoiding detection errors caused by loose parts.

[0097] The detection fixing position on the detection fixture 134 cooperates with the second mounting position on the second fixing part 133, allowing the detection fixture 11 to be finely adjusted when necessary to adapt to changes in different workpiece sizes or detection requirements. This fine-tuning capability improves the adaptability and flexibility of the detection structure, ensuring detection results under different production conditions.

[0098] The combination of the second locking component and the detection fixing position forms a modular connection between the detection component 11 and the detection fixing component 134. This design facilitates the replacement or upgrading of the detection component 11 without requiring large-scale adjustments to the entire detection structure, reducing maintenance costs and simplifying the equipment upgrade process.

[0099] Furthermore, the inspection fastener 134 includes:

[0100] The first fastener is disposed on the second fastening part 133;

[0101] The second fixing member has a fixing surface that forms a fixed angle with the fixing surface of the first fixing member. The detection member 11 is disposed on the second fixing member. The first fixing member and the second fixing member are L-shaped.
