[0044] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The following describes the embodiments by referring to the attached Figures 1 - 9 The described embodiments are exemplary and are intended to explain the embodiments of the present invention, and should not be construed as a limitation to the present invention.

[0046] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0047] In the embodiments of the present invention, unless otherwise clearly specified and limited, terms such as "mounted", "connected", "coupled", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0048] In one embodiment of the present invention, as Figures 1 - 9 shown, a pipe automatic loading device is provided, which includes a frame 10, and a material taking mechanism 20, a limiting and pressing mechanism 30, and at least two sets of loading mechanisms 40 provided on the frame 10. The two loading mechanisms 40 are drivingly connected and arranged side by side; the two loading mechanisms 40 each include a loading assembly 41, a chain transmission assembly 42, and a clamping and positioning assembly 43; the loading assembly 41 is connected to the side of the frame 10 and is located at the front end of the chain transmission assembly 42, and is used for loading the pipe 50; the chain transmission assembly 42 is used for conveying the pipe 50 loaded by the loading assembly 41; the limiting and pressing mechanism 30 is located at the front end of the chain transmission assembly 42, and is used for limiting the single-pass of the pipe 50; the clamping and positioning assembly 43 is arranged at the tail end of the chain transmission assembly 42, and is used for clamping and positioning the pipe 50 conveyed to the tail end of the chain transmission assembly 42; the material taking mechanism 20 is located on one side of the tail end of the chain transmission assembly 42, and the material taking mechanism 20 is used for adsorbing the clamped and positioned pipe 50 and moving the pipe 50 to the next working station.

[0049] Specifically, for the automatic pipe feeding device according to the embodiments of the present invention, the feeding assembly 41, the chain conveying assembly 42, and the clamping and positioning assembly 43 are all connected to the frame 10. The number of the feeding mechanisms 40 can be multiple groups, but at least two groups. During use, the pipes 50 are placed on the two feeding assemblies 41. The two feeding assemblies 41 are drivingly connected and arranged side by side to ensure the stable and synchronous transportation of the pipes 50. Since the limiting and pressing mechanism 30 is located at the front end of the chain conveying assembly 42, the feeding assembly 41 conveys the pipes 50 onto the chain conveying assembly 42, and the pipes 50 are transported from the front end to the tail end by the two chain conveying assemblies 42. Among them, the limiting and pressing mechanism 30 can preset parameters according to the thickness of the pipes 50, so that when the pipes 50 pass through the limiting and pressing mechanism 30 for material limiting, only one pipe 50 can pass through the limiting and pressing mechanism 30 at a time. The pipes 50 passing through the limiting and pressing mechanism 30 are conveyed to the clamping and positioning assembly 43 by the chain conveying assembly 42. The clamping and positioning assembly 43 clamps and positions the pipes 50. The material taking mechanism 20 moves in the direction close to the feeding mechanism 40 to adsorb the positioned pipes 50, and then moves the pipes 50 in the direction away from the feeding mechanism 40. In this way, the precise automatic feeding of the pipes 50 is realized, saving labor costs, time and effort, and having high efficiency.

[0050] Further, the two chain conveying assemblies 42 are connected by being connected to the first rotating rod 61, and the first rotating rod 61 is connected to the first transmission element 60. In this way, the synchronous operation of the two chain conveying assemblies 42 is realized, ensuring the stability of the pipes 50 during transmission.

[0051] Further, each of the two feeding assemblies 41 includes a feeding frame 411, a belt 412, a winding drum 413, and a fixed roller 414. The winding drum 413 and the fixed roller 414 are both rotatably connected to the frame 10, and the winding drum 413 is located below the fixed roller 414. The horizontal height of the highest point of the feeding frame 411 is greater than the horizontal height of the conveying surface of the chain conveying assembly 42. The feeding frame 411 is fixedly connected to the frame 10. One end of the belt 412 is connected to the top of the feeding frame 411, and the other end is wound around the fixed roller 414 and connected to the winding drum 413. The two winding drums 413 are connected by a second rotating rod 71, and the second rotating rod 71 is connected to the second transmission element 70. When the second transmission element 70 is started, it drives the second rotating rod 71 to rotate. The second rotating rod 71 drives the winding drum 413 to rotate, and the winding drum 413 winds up the belt 412, causing the pipes 50 placed on the belt 412 to move upward. Since the horizontal height of the highest point of the feeding frame 411 is greater than the horizontal height of the conveying surface of the chain conveying assembly 42, when the belt 412 is tightened, it is ensured that the pipes 50 in contact with the belt 412 can enter the chain conveying assembly 42 along the belt 412. In this way, the lifting feeding of the pipes 50 is realized.

[0052] In another embodiment of the present invention, as Figures 1 - 6As shown, the limiting and pressing mechanism 30 includes a first sensor (not labeled in the drawings), a pressing component 31, and an auxiliary ejecting component 32. The pressing component 31 and the auxiliary ejecting component 32 are arranged opposite to each other vertically. The pressing component 31 is disposed above the chain conveying component 42, and the auxiliary ejecting component 32 is connected to the side of the chain conveying component 42. The first sensor is located on the side of the pressing component 31 away from the feeding component 41, and the first sensor is electrically connected to the pressing component 31 and the auxiliary ejecting component 32 respectively. Specifically, the first sensor, the pressing component 31, and the auxiliary ejecting component 32 are all arranged on the frame 10. The pressing component 31 is slidably connected to the top of the frame 10, the auxiliary ejecting component 32 is slidably connected to the bottom of the frame 10, and the first sensor is located beside the pressing component 31 and the auxiliary ejecting component 32. When the pipe 50 is fed to the chain conveying component 42 by the feeding component 41, the pressing component 31 and the auxiliary ejecting component 32 approach each other, and the distance between them only allows one pipe 50 to pass through. After the pipe 50 passes through the pressing component 31, the first sensor senses the pipe 50. Since the first sensor is electrically connected to the pressing component 31 and the auxiliary ejecting component 32 respectively, the pressing component 31 moves downward, or the auxiliary ejecting component 32 moves upward, or the pressing component 31 moves downward while the auxiliary ejecting component 32 moves upward, so as to press the pipe 50 located between the pressing component 31 and the auxiliary ejecting component 32, preventing multiple pipes 50 from passing through the pressing component 31 and the auxiliary ejecting component 32 at the same time, and avoiding affecting the clamping and positioning of the pipe 50 by the clamping and positioning component 43. After the pipe 50 is taken by the material taking mechanism 20, the first sensor drives the pressing component 31 to reset.

[0053] In another embodiment of the present invention, as Figures 1 - 4 shown, the pressing component 31 includes a downward pressing driving member 311, a moving frame 312, and a pressing seat 313. The downward pressing driving member 311 is disposed on the top of the frame 10, and the moving frame 312 is connected to the moving end of the downward pressing driving member 311. The pressing seat 313 is disposed at the bottom of the moving frame 312, and a guiding inclined surface 3131 is provided on the side of the pressing seat 313 close to the feeding component 41. Specifically, the downward pressing driving member 311 is fixedly connected to the frame 10. When the feeding component 41 feeds materials, since a guiding inclined surface 3131 is provided on the side of the pressing seat 313 close to the feeding component 41, the guiding inclined surface 3131 enables the pipe 50 to enter the chain conveying component 42 better. After the pipe 50 passes through once, the downward pressing driving member 311 drives the moving frame 312 to move downward, the moving frame 312 drives the pressing seat 313 to move downward, and the pressing seat 313 and the auxiliary ejecting component 32 press the pipe 50 tightly.

[0054] In another embodiment of the present invention, as Figures 1 - 3 and Figure 6As shown, the auxiliary blanking component 32 includes a driving motor 321, a motor fixing seat 322, a lead screw 323, a moving plate 324, a first driving cylinder 325 and a blanking plate 326; the motor fixing seat 322 is connected to the frame 10, the driving motor 321 is arranged on the motor fixing seat 322, the output end of the driving motor 321 is connected to the lead screw 323, and the moving plate 324 is rotationally connected to the lead screw 323; the first driving cylinder 325 is fixed on the moving plate 324, the blanking plate 326 is connected to the moving end of the first driving cylinder 325, and the first driving cylinder 325 is used to drive the blanking plate 326 to move up and down. Specifically, the motor fixing seat 322 is used to fix the driving motor 321 beside the chain conveying component 42. Since the main shaft of the driving motor 321 is connected to the lead screw 323, the driving motor 321 can drive the lead screw 323 to rotate. Also, the moving plate 324 is rotationally connected to the lead screw 323, and the first driving cylinder 325 is fixedly connected to the moving plate 324. When the lead screw 323 rotates, the moving plate 324 moves relative to the lead screw 323, thereby driving the first driving cylinder 325 to move horizontally, and further adjusting the position of the blanking plate 326 to meet the requirements.

[0055] In another embodiment of the present invention, as Figures 1 - 3 and Figure 7 shown, the limiting and pressing mechanism 30 further includes a material blocking component 33. The material blocking component 33 includes a first linear driving member 331 and a material blocking plate 332. The first linear driving member 331 is arranged on the top of the frame 10 and beside the downward pressing driving member 311; the material blocking plate 332 is connected to the moving end of the first linear driving member 331 and is driven by the first linear driving member 331 to move linearly up and down. Specifically, the material blocking component 33 is arranged on the same side as the pressing component 31. After the pipe 50 passes through the pressing seat 313, the first linear driving member 331 drives the material blocking plate 332 to move downward to block the conveyance of the pipe 50 and prevent multiple pipes 50 from passing through the pressing seat 313, which affects the normal positioning and clamping of the clamping and positioning component 43.

[0056] In another embodiment of the present invention, as Figures 1 - 5As shown, the clamping and positioning component 43 includes a second sensor (not labeled in the drawings) disposed on the frame 10, a flipping and clamping member 431, and a shaping and positioning member 432. The flipping and clamping member 431 is located beside the chain conveying component 42, and the flipping and clamping member 431 and the shaping and positioning member 432 are disposed opposite to each other. The flipping and clamping member 431 is used to clamp and fix the pipe 50 conveyed above the flipping and clamping member 431. The second sensor is electrically connected to the flipping and clamping member 431 and the shaping and positioning member 432 respectively, and the second sensor is disposed beside the flipping and clamping member 431. Specifically, both the flipping and clamping member 431 and the shaping and positioning member 432 are located at the tail end of the chain conveying component 42. When the pipe 50 is conveyed by the chain conveying component 42 and passes through the second sensor, the second sensor transmits an electrical signal to the flipping and clamping member 431 and the shaping and positioning member 432. The flipping and clamping member 431 is activated to clamp and fix the pipe 50, and then the shaping and positioning member 432 is activated to shape the pipe 50. In this way, the position of the pipe 50 is adjusted to meet the normal material taking of the material taking mechanism 20. When the material taking mechanism 20 takes the material, the shaping and positioning member 432 and the flipping and clamping member 431 release the fixation on the pipe 50.

[0057] Further, the second sensor is electrically connected to the chain conveying component 42. When the second sensor detects the pipe 50, the chain conveying component 42 stops rotating. After the pipe 50 is taken by the material taking mechanism 20, the chain conveying component 42 operates normally.

[0058] In another embodiment of the present invention, as Figure 8As shown, the flipping clamping member 431 includes a mounting base 4311, a retaining pipe plate 4312, a flipping plate 4313, a double-acting cylinder 4314, a second driving cylinder 4315, and a cylinder fixing seat 4316. The mounting base 4311 is connected to the frame 10 and is located beside the chain conveying assembly 42. The retaining pipe plate 4312 is connected to the mounting base 4311, and the horizontal height of the retaining pipe plate 4312 is greater than the horizontal height of the conveying surface of the chain conveying assembly 42. The flipping plate 4313 is hinged to the mounting base 4311. The double-acting cylinder 4314 is arranged on the flipping plate 4313, and clamping pipes 4318 for clamping the pipe 50 are respectively arranged at two moving ends of the double-acting cylinder 4314. The cylinder fixing seat 4316 is connected to the bottom of the frame 10 and is located at the bottom of the chain conveying assembly 42. The second driving cylinder 4315 arranged obliquely is connected to the cylinder fixing seat 4316, and the telescopic end of the second driving cylinder 4315 is connected to the bottom of the flipping plate 4313. Specifically, when the pipe 50 is conveyed, the horizontal height of the flipping clamping member 431 is less than the horizontal height of the conveying surface of the chain conveying assembly 42. In this way, the flipping clamping member 431 is prevented from affecting the transportation of the pipe 50. When the pipe 50 passes the second sensor, the flipping clamping member 431 is located below the pipe 50. The cylinder fixing seat 4316 and the mounting base 4311 are not on the same vertical horizontal line, so that the second driving cylinder 4315 is arranged obliquely. The telescopic end of the second driving cylinder 4315 extends obliquely upward. Since the flipping plate 4313 is hinged to the mounting base 4311 and the telescopic end of the second driving cylinder 4315 is hinged to the flipping plate 4313, the flipping plate 4313 flips outward. At this time, the two clamping pipes 4318 on the double-acting cylinder 4314 are arranged perpendicular to the pipe 50, and the pipe 50 is located between the two clamping pipes 4318. Then, the double-acting cylinder 4314 drives the two clamping pipes 4318 to move towards each other, thereby clamping the pipe 50. The retaining pipe plate 4312 is located on the side of the fixing seat close to the material taking mechanism 20 and beside the double-acting cylinder 4314. The retaining pipe plate 4312 extends vertically upward, and the upper end of the retaining pipe plate 4312 extends out of the conveying surface of the chain conveying assembly 42, so as to prevent the pipe 50 from falling from the tail end of the chain conveying assembly 42.

[0059] In another embodiment of the present invention, as Figure 8As shown, the flipping and clamping member 431 further includes a support roller 4317. The support roller 4317 is rotatably connected to the flipping plate 4313 and is located beside the double-acting cylinder 4314. The support roller 4317 is used to support the pipe 50. Specifically, when the flipping and clamping member 431 clamps the pipe 50, the support roller 4317 flips along with the flipping plate 4313. After flipping, the horizontal height of the highest point of the support roller 4317 is greater than the horizontal height of the conveying surface of the chain conveying assembly 42. The support roller 4317 supports the pipe 50, causing the pipe 50 to be separated from the chain conveying assembly 42. And due to the arrangement of the support roller 4317, it is convenient for the shaping and positioning member 432 to adjust the pipe 50 in the length direction.

[0060] In another embodiment of the present invention, as Figures 1 - 3 and Figure 9 shown, the shaping and positioning member 432 includes a second linear driving member 4321, a material shaping plate 4322, and an elastic positioning member 4323. The second linear driving member 4321 and the elastic positioning member 4323 are respectively located on both sides of the frame 10. The material shaping plate 4322 is connected to the moving end of the second linear driving member 4321, and the material shaping plate 4322 is disposed opposite to the elastic positioning member 4323. The elastic positioning member 4323 is disposed opposite to the flipping and clamping member 431. Specifically, when the position of the pipe 50 in the horizontal direction needs to be adjusted, after the pipe 50 is clamped by the flipping and clamping member 431, the second linear driving member 4321 drives the material shaping plate 4322 to move towards the pipe 50. The material shaping plate 4322 contacts the side end of the pipe 50 and pushes the pipe 50 towards the elastic positioning member 4323. The support roller 4317 rolls accordingly, facilitating the movement of the pipe 50 until one end of the pipe 50 contacts the elastic positioning member 4323 and compresses the elastic positioning member 4323. The pipe 50 is positioned and fixed by the flipping and clamping member 431 and the shaping and positioning member 432, and the pipe 50 is positioned to a fixed position to ensure the accuracy of material taking.

[0061] Further, the elastic positioning member 4323 includes a travel switch 43231, a mounting bracket 43232, a fixing plate 43233, four slide bars 43234, and four springs 43235. The mounting bracket 43232 is fixedly connected to the frame 10. The four slide bars 43234 are respectively slidably connected to the mounting bracket 43232. The four springs 43235 are respectively sleeved on the corresponding slide bars 43234. The four slide bars 43234 are all fixedly connected to the fixing plate 43233. There is a gap between the fixing plate 43233 and the mounting bracket 43232. The travel switch 43231 is installed on the mounting bracket 43232. The contact of the travel switch 43231 is arranged within the gap between the fixing plate 43233 and the mounting bracket 43232, and the travel switch 43231 is electrically connected to the second linear driving member 4321. When the blanking plate 4322 pushes the pipe 50 into contact with the fixing plate 43233 and pushes the fixing plate 43233 outwards, the fixing plate 43233 compresses the spring 43235, and the slide bar 43234 slides relative to the mounting bracket 43232, realizing the movement of the fixing plate 43233 towards the travel switch 43231 until the fixing plate 43233 contacts the contact of the travel switch 43231. The travel switch 43231 controls the second linear driving member 4321 to drive the blanking plate 4322 to reset. In this way, the positioning of the pipe 50 is ensured to be accurate.

[0062] In another embodiment of the present invention, as Figure 1 shown, the material taking mechanism 20 includes a lifting assembly 21, a horizontal linear driving assembly 22, and a pipe magnetic adsorption assembly 23. The horizontal linear driving assembly 22 is arranged on the top of the frame 10. The lifting assembly 21 is arranged on the moving end of the horizontal linear driving assembly 22. The pipe magnetic adsorption assembly 23 is arranged on the moving end of the lifting assembly 21 and is used to adsorb the pipe 50 on the clamping and positioning assembly 43. Specifically, after the flipping clamping member 431 and the shaping and positioning member 432 position the pipe 50, the horizontal linear driving assembly 22 drives the pipe magnetic adsorption assembly 23 to move towards the clamping and positioning assembly 43 until the pipe magnetic adsorption assembly 23 is located above the pipe 50. Then, the lifting assembly 21 drives the pipe magnetic adsorption assembly 23 to move downwards. The pipe magnetic adsorption assembly 23 is energized to generate a magnetic force to adsorb the pipe 50. The flipping clamping member 431 and the shaping and positioning member 432 release the clamping of the pipe 50. The lifting assembly 21 drives the pipe magnetic adsorption assembly 23 to move upwards, and the horizontal linear driving assembly 22 drives the pipe magnetic adsorption assembly 23 to move away from the feeding mechanism 40 to transport the pipe 50 to the next working station.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
