DETAILED DESCRIPTION

[0029] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, in one embodiment, a pipe detection mechanism 100 is provided, comprising a carrying body 110 and a length detection module 120. The carrying body 110 is provided with a first detection station 111 for carrying the pipe 20. A positioning member 112 for positioning and cooperating with one end of the pipe 20 is provided on one side of the first detection station 111, and a avoidance hole 113 is provided on the other side. The length detection module 120 is located on a side of the carrying body 110 close to the avoidance hole 113, and comprises a driving member 121, a mounting seat 122 transmission-connected to the driving member 121, a detection member 123, and a pressing member 124 mounted on the mounting seat 122. The detection member 123 is configured to detect the length of the pipe 20 when the driving member 121 drives the pressing member 124 through the avoidance hole 113 through the mounting seat 122 and presses the pipe 20 against the positioning member 112.

[0031] When the pipe fitting detection mechanism 100 in the above embodiment is used, after the pipe fitting 20 is transported to the first detection station 111, the driving member 121 drives the mounting seat 122 to move in the direction close to the supporting body 110, so that the clamping member 124 passes through the avoidance hole 113 and abuts against the end of the pipe fitting 20 away from the positioning member 112, so as to press the pipe fitting 20 tightly against the positioning member 112. At this time, the detection member 123 corresponds to the length of the detection pipe fitting 20, which can effectively avoid the risks of manual missed detection, misjudgment, etc., and improve the detection accuracy and efficiency of the pipe fitting 20.

[0032] The driving member 121 may be configured as a telescopic cylinder, a telescopic hydraulic rod, a telescopic motor or other linear drive structures. The pressing member 124 may be configured as a pressing rod, a pressing column or other pressing structures.

[0033] Among them, the detection member 123 can be set as a device that directly detects the length of the pipe fitting 20 (such as a visual sensor or an industrial camera, etc.), or it can be set as a device that indirectly detects the length of the pipe fitting 20 by detecting the position of one end of the pipe fitting 20 away from the positioning member 112, or by detecting the movement displacement of the clamping member 124 (such as a displacement sensor).

[0034] like Figure 3 As shown, the detection member 123 further includes a length sensor 1231 mounted on the mounting seat 122 and provided with an elastically compressible probe 1232. The pressing member 124 includes a pressing push rod 1241, one end of which is transmission-connected to the probe 1232, and the other end is arranged corresponding to the avoidance hole 113. The mounting seat 122 has a detection position. When the driving member 121 drives the mounting seat 122 to move along the axis of the avoidance hole 113 to the detection position, the pressing push rod 1241 presses the pipe 20 against the positioning member 112 and compresses the probe 1232, so that the length sensor 1231 detects the length of the pipe 20. In this way, the pipe 20 is transported to the first inspection station 111, and the driving member 121 drives the mounting seat 122 to move in the direction close to the supporting body 110, so that the clamping member 124 passes through the avoidance hole 113 and presses the pipe 20 tightly against the positioning member 112. Then, the driving member 121 continues to drive the mounting seat 122 to move in the direction close to the supporting body 110. At this time, the clamping push rod 1241 is blocked by the pipe 20 and cannot continue to move, and is forced to push the probe 1232 of the length sensor 1231 in the opposite direction to compress until the mounting seat 122 moves to the inspection position, so that the length sensor 1231 indirectly detects the length of the pipe 20 through the compression amount of the probe 1232, thereby improving the practicality of the pipe inspection mechanism 100.

[0035] It should be noted that the pipe detection mechanism 100 in this embodiment needs to be calibrated using a length standard before detecting the length of the pipe 20 .

[0036] like Figure 2 and Figure 3 As shown, optionally, a guide portion is provided on the mounting seat 122, and the guide portion cooperates with the pressing push rod 1241 to guide along the axis direction of the avoidance hole 113. In this way, the guide portion can guide the pressing push rod 1241, ensuring that the pressing push rod 1241 stably and reliably passes through the avoidance hole 113 along the axis direction of the avoidance hole 113 and presses the pipe 20 against the positioning member 112, thereby improving the reliability of the pipe detection mechanism 100.

[0037] The guide portion may be configured as a guide groove, a guide hole 1223 , a guide bracket or other guide structures.

[0038] like Figure 2 and Figure 3 As shown, in one embodiment, the mounting seat 122 is provided with a first mounting portion 1221 and a second mounting portion 1222 spaced apart along the axial direction of the avoidance hole 113. The length sensor 1231 is mounted on the first mounting portion 1221, and the second mounting portion 1222 is located on a side of the first mounting portion 1221 close to the avoidance hole 113. The guide portion is provided as a guide hole 1223, and the guide hole 1223 is provided on the second mounting portion 1222. In this way, the mounting seat 122, the first mounting portion 1221, and the second mounting portion 1222 are arranged to form a groove, and the probe 1232 is correspondingly located in the groove, so that the first mounting portion 1221 and the second mounting portion 1222 can both block external objects, reduce interference caused by contact between external objects and the probe 1232, ensure that the probe 1232 can be accurately and reliably elastically compressed, and improve the detection accuracy of the pipe detection mechanism 100.

[0039] like Figure 3 As shown, optionally, a limiting portion 1242 is provided at one end of the pressing push rod 1241 away from the avoidance hole 113. The probe 1232 is in transmission connection with the limiting portion 1242 and is configured to limit the limiting portion 1242 to the second mounting portion 1222 when the pressing push rod 1241 is not pressing the pipe 20 at the first inspection station 111. In this way, before and after the pressing push rod 1241 presses the pipe 20 at the first inspection station 111, the probe 1232 can limit the pressing push rod 1241 through the limiting portion 1242, so that the position of the pressing push rod 1241 relative to the mounting seat 122 remains fixed, avoiding other secondary problems caused by the movement or shaking of the pressing push rod 1241, and improving the reliability of the pipe inspection mechanism 100.

[0040] Specifically in this embodiment, the limiting portion 1242 is configured as a limiting plate. The outer diameter of the limiting plate is larger than the inner diameter of the guide hole 1223 and is integrally formed with the pressing push rod 1241. A pressing block 1243 is mounted on the end of the pressing push rod 1241 away from the limiting portion 1242. The outer wall profile of the pressing block 1243 is adapted to the inner wall profile of the avoidance hole 113. The positioning member 112 is provided with a reference surface for close contact with the end face of the pipe fitting 20. The reference surface is arranged parallel to the outer end face of the pressing block 1243.

[0041] like Figure 2 As shown, in one embodiment, a mounting hole 114 is provided on a side of the first inspection station 111 away from the avoidance hole 113. A positioning member 112 is removably mounted in the mounting hole 114. This allows the positioning member 112 to be flexibly replaced to accommodate different pipes 20 as needed, thereby improving the practicality of the pipe inspection mechanism 100.

[0042] The positioning member 112 may be configured as a positioning seat, a positioning block, or other positioning structures. In other embodiments, the positioning member 112 may also be integrally formed with the supporting body 110 .

[0043] like Figure 4 As shown, in one embodiment, a pipe production line 10 is provided, comprising a mounting body 200 having a material-removing station 201, a material-unloading mechanism 300, a conveying mechanism 400, and the pipe inspection mechanism 100 of any of the above-described embodiments. The material-unloading mechanism 300 is mounted on the mounting body 200 and is used to convey pipes 20 to the material-removing station 201. The conveying mechanism 400 is used to convey the pipes 20.

[0044] In the above-described embodiment, when the pipe production line 10 is in use, the unloading mechanism 300 first unloads the pipe 20 and transports it to the material-waiting station 201. Next, the transport mechanism 400 transports the pipe from the material-waiting station 201 to the first inspection station 111. Then, the length detection module 120 is activated to detect the length of the pipe 20. Finally, after the pipe 20 is inspected, the transport mechanism 400 moves the pipe 20 to the next process step, and the above steps are repeated, achieving automatic and continuous inspection of the pipe 20 and improving the practicality of the pipe production line 10.

[0045] like Figure 2 and Figure 4As shown, the pipe production line 10 optionally further includes a sorting mechanism 500 and a controller. The carrier body 110 is further provided with a material unloading station 115. A material guide 116 is provided at the material unloading station 115. The material guide 116 interfaces with the sorting mechanism 500 and is configured to guide the pipes 20 at the material unloading station 115 to the sorting mechanism 500 when the transport mechanism 400 transports the pipes 20 to the material unloading station 115. The sorting mechanism 500 is used to sort and transport the inspected pipes 20. The controller is communicatively connected to the material unloading mechanism 300, the pipe inspection mechanism 100, the transport mechanism 400, and the sorting mechanism 500. In this way, the standard length and detection tolerance are pre-set in the length detection module 120. The length detection module 120 detects the actual length of the pipe 20 and determines whether the pipe 20 is qualified based on the actual length, the standard length, and the detection tolerance. The length detection module 120 feeds back the detection results to the controller, so that the controller can control the sorting mechanism 500 to classify and transport the pipe 20 according to the detection structure, thereby improving the practicality of the pipe production line 10.

[0046] The material guiding portion 116 may be configured as a material guiding rail, a material guiding slope, or other structures capable of guiding the pipe fittings 20 at the unloading station 115 to the sorting mechanism 500 .

[0047] Specifically, in this embodiment, the unloading mechanism 300, the transport mechanism 400, the pipe inspection mechanism 100, and the sorting mechanism 500 are all mounted on the mounting body 200. The controller can be configured as a single-chip microcomputer, a programmable logic controller, or other control structure. The controller can be connected to the unloading mechanism 300, the pipe inspection mechanism 100, the transport mechanism 400, and the sorting mechanism 500 via a data cable, electrical wires, Bluetooth, wireless network communication technology, or other communication methods.

[0048] The sorting mechanism 500 can be configured as any conventional structure capable of sorting and conveying the pipes 20. Specifically, in this embodiment, the sorting mechanism 500 includes a sorting body 510 with at least two sorting channels 511, a rotary cylinder connected to a controller, and a swing arm 520 connected to the rotary cylinder. The rotary cylinder is used to drive the swing arm 520 to swing, causing it to switch between sorting channels 511.

[0049] Specifically, in this embodiment, a support rack is mounted on the mounting body 200 and is positioned between the unloading mechanism 300 and the pipe inspection mechanism 100. A material removal station 201 is located on the support rack. The pipe production line 10 also includes a photoelectric sensor 202, which is communicatively connected to the controller. The photoelectric sensor 202 is mounted on the support rack and is configured to trigger when a pipe 20 is delivered to the material removal station 201.

[0050] The blanking mechanism 300 can be configured as any structure in the prior art that can blank the pipe 20 .

[0051] like Figure 5 As shown, specifically in this embodiment, the unloading mechanism 300 includes a hopper 310 for inputting and storing pipes 20, a motor 321, a reducer 322 drivingly connected to the motor 321, a coupling 323 drivingly connected to the reducer 322, a drive shaft 324 drivingly connected to the coupling 323, a unloading roller 325 sleeved on the drive shaft 324, and a proximity sensor 326. The unloading roller 325 is rotatably disposed below the hopper 310 to rotatably convey the pipes 20. The proximity sensor 326 is located at the discharge position of the unloading roller 325 to detect the discharged pipes 20 (i.e., the proximity sensor 326 is configured to be triggered when the unloading roller 325 moves the pipes 20 to the discharge position but does not release the pipes 20). When both the proximity sensor 326 and the photoelectric sensor 202 are triggered, the controller controls the motor 321 to stop operating.

[0052] like Figure 2 As shown, in one embodiment, the supporting body 110 is further provided with a second inspection station 117 for supporting the pipe 20, and a third inspection station 118 for supporting the pipe 20. The pipe inspection mechanism 100 also includes an outer diameter inspection module and an inner diameter inspection module. The outer diameter inspection module is installed at the second inspection station 117 and is used to detect the outer diameter of the pipe 20. The inner diameter inspection module is installed at the third inspection station 118 and is used to detect the inner diameter of the pipe 20. In this way, the length inspection module 120, the outer diameter inspection module, and the inner diameter inspection module can respectively inspect the length, outer diameter, and inner cavity of the pipe 20, thereby improving the practicality of the pipe inspection mechanism 100.

[0053] The positions of the first inspection station 111, the second inspection station 117, and the third inspection station 118 can be interchanged according to actual needs. The outer diameter detection module can be configured as any structure in the prior art capable of detecting the outer diameter of the pipe 20. The inner diameter detection module can be configured as any structure in the prior art capable of detecting the inner diameter of the pipe 20.

[0054] like Figure 2 and Figure 4 As shown, further, the material-taking station 201, the first detection station 111, the second detection station 117, the third detection station 118 and the material-unloading station 115 are arranged along a preset linear direction (such as Figure 2The pipes 20 are arranged sequentially (in the direction indicated by A in FIG), and the spacing between any two adjacent workstations is the same. The transport mechanism 400 is used to simultaneously transport the pipes 20 at the material removal station 201, the pipes 20 at the first inspection station 111, the pipes 20 at the second inspection station 117, and the pipes 20 at the third inspection station 118. In this way, each workstation can share a single transport mechanism 400 to transport the pipes 20, reducing the number of transport mechanisms 400 and lowering the cost of the pipe production line 10.

[0055] like Figure 6 As shown, the transport mechanism 400 optionally includes a first linear slide 410 mounted on the mounting body 200, a second linear slide 420 mounted on the first linear slide 410, and a transport base 430 mounted on the second linear slide 420. The first linear slide 410 is used to drive the second linear slide 420 to move perpendicular to a preset linear direction. The second linear slide 420 is used to drive the transport base 430 to move along a preset linear direction. The preset linear direction can be set to a horizontal direction or an inclined direction. The transport base 430 is provided with at least one supporting portion 431 for supporting the pipe 20. Each supporting portion 431 is arranged corresponding to a respective workstation on the supporting body 110, so as to be able to simultaneously transport the pipe 20 at the waiting station 201, the pipe 20 at the first inspection station 111, the pipe 20 at the second inspection station 117, and the pipe 20 at the third inspection station 118.

[0056] Specifically in this embodiment, the support portion 431 can be configured as a support trough. There are two support troughs, which are spaced sequentially along a predetermined linear direction, and the spacing between any two adjacent support troughs is the first spacing. The spacing between any two adjacent stations among the material pickup station 201, the first inspection station 111, the second inspection station 117, the third inspection station 118, and the unloading station 115 is the second spacing. The first spacing is equal to the second spacing.

[0057] In other embodiments, the transport mechanism 400 may further include a robotic arm and a mechanical clamp mounted at the end of the robotic arm. The mechanical clamp has multiple clamping stations to simultaneously clamp and hold the pipe 20 at the material removal station 201, the pipe 20 at the first inspection station 111, the pipe 20 at the second inspection station 117, and the pipe 20 at the third inspection station 118.

[0058] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0059] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0060] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0061] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0062] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0063] It should also be understood that when explaining the connection relationship or positional relationship of elements, even if not explicitly described, the connection relationship and positional relationship should be interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately," "approximately," or "substantially" can mean within one or more standard deviations, which is not limited here.

[0064] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
