Technical Field

[0001] The present invention belongs to the technical field of disordered feeding of copper tubes, and particularly relates to a copper tube feeding mechanism. Background Art

[0002] Due to the excellent performance of copper tubes, they are used in various aspects. In particular, copper tubes are important components of air conditioners. Air conditioner copper tubes are mainly used to convey refrigerants and ensure the circulation of refrigerants. Therefore, the quality of air conditioner copper tubes is particularly important. During the use of copper tubes, it is necessary to perform welding processing on copper tubes of a certain length. When the copper tubes enter the welding line, in most cases, it is necessary for workers to individually place the cut copper tubes into the tooling fixtures one by one and then flow into the welding line for welding operations. With the increasing requirements of enterprises for production rhythm, manual feeding has disadvantages such as low efficiency and high error rate.

[0003] Therefore, it is urgent to design a copper tube feeding mechanism to solve the technical problems of low efficiency and high error rate in the existing disordered feeding of copper tubes. Summary of the Invention

Detailed implementation manners

[0027] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without creative work belong to the scope of protection of the present invention. In the description of the present invention, it should be noted that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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 the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figures 1 to 6 As shown, an embodiment of the present invention provides a copper tube feeding mechanism, including a frame 1, a driving structure, a detection structure 4, a rotating structure 5, a silo 6, a feeding structure 9 and a reset structure 10. The frame 1 is used to support the entire mechanism, and the driving structure, the detection structure 4, the rotating structure 5, the silo 6, and the feeding structure 9 are all arranged on the frame 1, so that the frame 1 supports the operation of the copper tube feeding mechanism. The frame 1 can also be connected to other structures so that the copper tube feeding mechanism and other structures can be matched. Of course, it can be understood that the copper tube feeding mechanism can also be set as other feeding structures, and pipe fittings of other materials can also be placed in the silo 6, as long as the disordered feeding of the pipe fittings is achieved. The pipe fittings are placed in the silo 6, and the pipe fittings in the silo 6 are controlled by the linkage of the driving structure, the detection structure 4 and the rotating structure 5, so that the pipe fittings are automatically dropped by the feeding structure 9, and the disordered feeding of the pipe fittings is achieved, thereby improving labor production efficiency.

[0031] Furthermore, the frame 1 is movably connected with a bin 6. A driving structure is arranged on one side of the bin 6. The driving structure is connected to the rotating structure 5. A rotatable chute structure 110 is arranged on one side of the rotating structure 5. The driving structure drives the bin 6 to move horizontally. The discharge port 62 of the bin 6 is aligned with the chute structure 110. The copper tubes 7 in the bin 6 fall into the chute structure 110 through the discharge port 62. The chute structure 110 is rotated to enable the copper tubes 7 to automatically fall along the blanking structure 9. By simultaneously driving the movement of the rotating structure 5 and the bin 6 through the driving structure, the discharge port 62 corresponds to the chute structure 110, ensuring that the copper tubes 7 fall into the chute structure 110 through the discharge port 62. Then, the chute structure 110 is rotated to change the movement posture of the copper tubes 7, and the copper tubes 7 are made to fall into the blanking structure 9, thereby realizing the disordered feeding of the copper tubes 7.

[0032] Furthermore, the frame 1 includes a first mounting plate 11, a second mounting plate 12, and a first fixing plate 13. The first mounting plate 11 and the second mounting plate 12 are vertically arranged. The number of the first mounting plates 11 includes at least two. The bottoms of at least two first mounting plates 11 are respectively vertically arranged on the upper surface of the second mounting plate 12. Of course, it can be understood that the number of the first mounting plates 11 can be two or can be set to multiple, as long as the supporting function can be realized. The first fixing plate 13 is fixedly connected to the side wall of the first mounting plate 11, so that the detection structure 4, the rotating structure 5, the driving structure, and the moving structure 3 are fixed on the first fixing plate 13.

[0033] Furthermore, the moving structure 3 includes a slide rail 14 and a slider 15. The slide rail 14 is arranged on the first fixing plate 13. The number of the slide rails 14 can include one, two, or multiple. Each slide rail 14 is provided with a slider 15, so that the slider 15 can slide on the slide rail 14. Of course, it can be understood that the number of the sliders 15 and the slide rails 14 is not specifically limited here. The number of the sliders 15 and the slide rails 14 is designed according to the size structure of the bin 6.

[0034] Furthermore, the bin 6 is fixedly connected to the slider 15. The slide rail 14 drives the slider 15 to move horizontally, so that the bin 6 moves horizontally along the first fixing plate 13. Furthermore, the discharge port 62 of the bin 6 is driven to move horizontally. The discharge port 62 is blocked or the discharge port 62 is aligned with the positioning groove 111 of the chute structure 110 to realize the blanking of the copper tubes 7.

[0035] Of course, it can be understood that as an alternative embodiment, the moving structure 3 can also be set as a cylinder, and the bin 6 is driven to move horizontally by the cylinder. However, the slide rail 14 and the slider 15 are superior to the cylinder because the stroke of the cylinder is smaller. Therefore, the adjustment range of using the slide rail 14 and the slider 15 is larger. Of course, it can also be set according to the actual moving stroke requirement of the bin 6.

[0036] As a preferred embodiment, the cross-sectional area of the silo 6 has an inverted triangular structure, so that the arrangement of the copper tubes 7 shows a trend of gradually decreasing along each row, thereby realizing the disordered feeding of the copper tubes 7. Due to the self-weight of the copper tubes 7, the copper tubes 7 freely fall.

[0037] Furthermore, the interior of the silo 6 has a receiving chamber, and the receiving chamber includes a first side wall 63 and a second side wall 64. The first side wall 63 and the second side wall 64 intersect to form an included angle. Of course, it can be understood that the first side wall 63 and the second side wall 64 are inclined, and the included angle formed by the first side wall 63 and the second side wall 64 is not greater than 120°, so that the copper tubes 7 can freely and quickly fall, ensuring the continuity of the falling of the copper tubes 7. At the bottom where the first side wall 63 and the second side wall 64 intersect, there is a discharge port 62, and the discharge port 62 is arranged at the bottom of the silo 6, so that the copper tubes 7 fall to the discharge port 62 under the action of their own gravity for discharging.

[0038] As a preferred embodiment, the diameter of the discharge port 62 is greater than one times the outer diameter of the copper tube 7 and less than two times the outer diameter of the copper tube 7, so that one copper tube 7 falls to the discharge port 62 for discharging, avoiding the discharging of two copper tubes 7. Of course, it can be understood that the diameter of the discharge port 62 is preferably slightly greater than one times the outer diameter of the copper tube 7, so that each copper tube 7 can be discharged in sequence, realizing the rapid feeding of each copper tube 7.

[0039] Furthermore, a conveying wheel 61 is arranged in the silo 6. The conveying wheel 61 is connected to a driving motor, and the driving motor drives the rotation of the conveying wheel 61. The conveying wheel 61 rolls with the copper tubes 7 in the receiving chamber of the silo 6, and the friction between the conveying wheel 61 and the copper tubes 7 is used to accelerate the falling of the copper tubes 7. As a preferred embodiment, the material of the conveying wheel 61 is made of plastic material to avoid damaging the copper tubes 7 during the friction between the conveying wheel 61 and the copper tubes.

[0040] Furthermore, the discharge port 62 of the silo 6 has a certain length and can accommodate multiple copper tubes 7 arranged in sequence to realize the rapid feeding of the copper tubes 7 and avoid the feeding time of the copper tubes 7 being prolonged due to the copper tubes 7 falling into the discharge port 62 in sequence.

[0041] Furthermore, a positioning block 103 is arranged on the outer wall of the silo 6. The positioning block 103 is used to support the inverted triangular structure at the bottom of the silo 6, so that the silo 6 is stably arranged on the slider 15.

[0042] Furthermore, a pushing component 53 is arranged between the driving structure and the rotating structure 5. The driving structure synchronously drives the silo 6 to move horizontally and the rotating structure 5 to rotate, so that the discharge port 62 of the silo 6 is aligned with the chute structure 110, thereby realizing the automatic falling of the copper tubes 7.

[0043] Specifically, the driving structure includes a motor 2, which is fixedly arranged on the first fixing plate 13. The motor 2 is arranged on one side of the first mounting plate 11. The motor shaft of the motor 2 penetrates through the first fixing plate 13 and extends to the other side of the first fixing plate 13. The motor shaft is connected to the cam 51, so that the rotation of the motor 2 drives the rotation of the cam 51.

[0044] Further, the third mounting plate 16 is arranged on the slider 15. The material bin 6 is connected to the third mounting plate 16. The third mounting plate 16 is provided with a third roller 55. After the cam 51 rotates, the cam 51 abuts against the third roller 55. As the cam 51 continues to rotate, the cam 51 drives the third roller 55 to move in a direction away from the cam 51, so that the third mounting plate 16 moves in a direction away from the cam 51, and then drives the slider 15 to move in a direction away from the cam 51, thereby causing the material bin 6 to move in a direction away from the cam 51. Therefore, the cam 51 drives the discharge port 62 of the material bin 6 to align with the positioning groove 111 of the chute structure 110, thus realizing the automatic blanking of the copper tube 7.

[0045] As a preferred embodiment, the shape of the cam 51 is oval, so that the cam 51 has a major axis and a minor axis. When the cam 51 is in the initial state, that is, the discharge port 62 of the material bin 6 is blocked and the material bin 6 is not aligned with the positioning groove 111 of the chute structure 110. At this time, the angle between the axis where the major axis of the cam 51 is located and the vertical direction is set as an acute angle. Preferably, the angle between the axis where the major axis of the cam 51 is located and the vertical direction is set as an acute angle, and the acute angle is set as 30°. During the blanking process of the copper tube 7, the angle between the axis where the major axis of the cam 51 is located and the vertical direction continues to increase, so that the cam 51 drives the material bin 6 to move closer to the chute structure 110, and the discharge port 62 of the material bin 6 aligns with the positioning groove 111 of the chute structure 110, realizing the free blanking of the copper tube 7.

[0046] Further, a bracket 52 is arranged on the cam 51. Extension plates are arranged on the opposite sides of the bracket 52. The extension plates cooperate with the detection structure 4, and the detection structure 4 detects the extension plates, thereby detecting the rotation angle of the cam 51.

[0047] Specifically, the detection structure 4 includes a positioning plate 41 and a sensor 43. The positioning plate 41 is fixedly connected to the first fixing plate 13 and is used for fixing the detection structure 4. The positioning plate 41 is arranged in an L-shaped plate structure. An adjusting plate 42 is arranged on the positioning plate 41. The adjusting plate 42 is perpendicular to the positioning plate 41. A plurality of adjusting holes are arranged on the adjusting plate 42, and the plurality of adjusting holes are used to adjust the position of the sensor 43, so that the sensor 43 can more quickly detect the rotation angle of the cam 51, and the sensor 43 can be adjusted according to the position height of the cam 51.

[0048] Further, the sensor 43 is disposed on the block structure of the concave-shaped structure, so that the extension plate is accommodated within the concave-shaped structure. Then, the rotation of the cam 51 drives the extension plate to move within the block structure of the concave-shaped structure, enabling the sensor 43 to detect the position of the extension plate, thereby determining the rotation angle of the cam 51, and further controlling the rotation or stop of the motor 2, so as to achieve the rapid feeding of the copper tube 7.

[0049] Further, the pushing assembly 53 includes a guide rail 532 which is fixedly connected to the frame 1. A slidable moving block 533 is arranged on the guide rail 532. A first roller 535 is disposed on the moving block 533, and a rotatable second roller 536 is arranged on the moving block 533, so that the cam 51 abuts against the first roller 535, driving the moving block 533 to move in a direction away from the cam 51, and the second roller 536 abuts against the rotating structure 5, thereby realizing the rotation of the rotating structure 5.

[0050] Specifically, a contact block 534 is arranged on the moving block 533, and the contact block 534 is connected to the first roller 535. A connecting shaft 537 is arranged at the bottom of the moving block 533, and the connecting shaft 537 is used to connect the second roller 536.

[0051] As Figure 7 shown, the guide rail 532 is fixedly arranged on the first fixing plate 13, and the guide rail 532 is disposed below the cam 51, so that after the cam 51 rotates, the cam 51 can abut against the first roller 535, thereby driving the first roller 535 to move in a vertical direction away from the cam 51. The first roller 535 is arranged on the moving block 533, and the moving block slides vertically on the guide rail 532, so that the second roller 536 arranged at the bottom of the moving block 533 moves in a vertical direction away from the cam 51. As a preferred embodiment, the shape of the moving block 533 can be set as an L-shaped block structure, so that the directions where the first roller 535 and the second roller 536 are located are perpendicular to each other, and further the first roller 535 and the second roller 536 can move in different directions.

[0052] Further, the second roller 536 is rotatably arranged on the moving block 533, so that the second roller 536 can rotate along the rotating shaft 541. The rolling of the second roller 536 can drive the rotation of the rotating structure 5. Of course, it can be understood that according to the different rotation directions of the cam 51, the second roller 536 can be driven to roll in the clockwise or counterclockwise direction, and further drive the rotating structure 5 to rotate in the clockwise or counterclockwise direction.

[0053] Further, the rotating structure 5 includes a connecting block 54. The connecting block 54 and the support block 8 are connected by a rotating shaft 541. The support block 8 is fixedly connected to the frame 1, and the rotating shaft 541 is connected to the chute structure 110, so that the pushing assembly 53 abuts against the connecting block 54, and the rotation of the connecting block 54 drives the chute structure 110 to rotate simultaneously.

[0054] Specifically, through holes are provided on the connecting block 54, and one end of the through hole is connected to the rotating shaft 541, so that the second roller 536 abuts against the connecting block 54. The second roller 536 drives the rotation of the connecting block 54, so that the connecting block 54 drives the rotation of the rotating shaft 541, and further drives the rotation of the chute structure 110, thereby realizing the transportation of the copper tube 7 on the chute structure 110 to the blanking structure 9, so that the copper tube 7 automatically drops.

[0055] Furthermore, the connecting block 54 and the chute structure 110 are respectively arranged at both ends of the rotating shaft 541. A support block 8 is arranged in the middle of the rotating shaft 541. An installation hole 82 is provided on the support block 8, and the rotating shaft 541 is arranged in the installation hole 82. Both ends of the rotating shaft 541 extend out of both ends of the support block 8. A first stepped surface 81 and a second stepped surface 83 are provided on the support block 8. The second stepped surface 83 of the support block 8 is matched with the convex edge provided on the side wall of the connecting block 54. The support block 8 abuts against the second stepped surface 83, and then the connecting block 54 drives the rotation of the rotating shaft 541, so that the chute structure 110 rotates synchronously.

[0056] Furthermore, the chute structure 110 includes a third body 112. A positioning groove 111 is provided on the top surface of the third body 112. The positioning groove 111 runs through the top surface of the third body 112. The groove body of the positioning groove 111 is adapted to the outer diameter of the copper tube 7, so that the copper tube 7 just falls into the positioning groove 111.

[0057] Furthermore, in the embodiment provided by the present invention, when the silo 6 is in the initial position, the discharge port 62 of the chute is blocked by the end face of the support block 8. The cam 51 drives the silo 6 to move at the same time, so that the discharge port 62 is aligned with the positioning groove 111 to realize the blanking of the copper tube 7. At this time, the cam 51 drives the rotation of the connecting block 54. Then, while the copper tube 7 falls into the positioning groove 111, the third body 112 rotates, so that the copper tube 7 rotates in the counterclockwise direction, and the copper tube 7 changes from a horizontal state to a vertical state, and then the copper tube 7 freely falls from the blanking structure 9 to realize the disordered feeding of the copper tube 7.

[0058] Furthermore, the blanking structure 9 includes a first body 92 and a second body 93. The first body 92 and the second body 93 are connected by a fixed shaft 94. Of course, it can be understood that the first body 92 and the second body 93 have the same shape and structure. The first body 92 and the second body 93 form a receiving groove 91. The copper tube 7 provided on the positioning groove 111 rotates by a certain angle, so that the copper tube 7 falls into the receiving groove 91.

[0059] As a preferred embodiment, a positioning groove 111 is provided on the chute structure 110. The positioning groove 111 is used to accommodate the copper tube 7. After the symmetry axes of the positioning groove 111 and the accommodating groove 91 are extended and intersected, an included angle is formed, so that the copper tube 7 falls from the bin 6 into the positioning groove 111 and rotates to the accommodating groove 91, thereby realizing the automatic feeding of the copper tube 7.

[0060] Furthermore, a reset structure 10 is provided on the frame 1. The reset structure 10 is connected to the bin 6. After the driving structure stops applying an external force, the reset structure 10 drives the bin 6 to move, so that the rotating structure 5 blocks the discharge port 62 to prevent the copper tube 7 from falling.

[0061] Specifically, the reset structure 10 includes a mounting block 101. The mounting block 101 is fixedly arranged on the first fixing plate 13. An elastic member is arranged on the mounting block 101. As a preferred embodiment, the elastic member can be set as a spring 102. When the external force applied by the cam 51 disappears, the restoring force of the spring 102 drives the bin 6 to return to the initial position, so that the embodiment provided by the present invention realizes automatic feeding or automatic stop of feeding, ensures the continuity of feeding, and avoids the accumulation of continuously falling copper tubes 7.

[0062] The operation process of the copper tube feeding mechanism provided by the present invention is as follows: When the copper tube feeding mechanism provided by the embodiment of the present invention is in operation, a copper tube 7 of a fixed length intercepted is manually placed into the bin 6. The internal structure of the bin 6 is an inverted triangular structure. There is a discharge port 62 with a certain length below the inverted triangle. The copper tubes 7 in the bin 6 will enter the discharge port 62 and be arranged in sequence under the action of gravity and their own shapes. The bin 6 is installed on the third mounting plate 16. The bin 6 is connected to the frame 1 through a guide rail 532. When feeding, the bin 6 is horizontally displaced to the right by the rotation of the cam 51 installed on the left side of the bin 6, and the spring 102 push rod installed on the right side of the bin 6 resets the bin 6. When the bin 6 provided by the embodiment of the present invention moves to the feeding position, the conveying wheel 61 in the feeding channel rotates to accelerate the copper tube 7 to fall out of the feeding channel. The conveying wheel 61 is driven by a motor. The driving motor is installed on the frame 1. The operation signal of the motor comes from the sensor 43 installed on the cam 51. When the cam 51 rotates, it pushes the bin 6 to move, and the signal of the sensor 43 is input, and the motor moves. The lower part of the cam 51 contacts the pushing component 53. During the rotation of the cam 51, while pushing the bin 6 to move, it also moves the pushing component 53 below it downward. The pushing component 53 is connected to the frame 1 through a guide rail 532 and a sliding member 531, drives the rotating shaft 541 to rotate, and the chute structure 110 containing the copper tube 7 rotates, and the copper tube 7 falls into the feeding structure 9 below the chute. The feeding structure 9 is provided with an optical fiber sensor 43 to detect whether there is material in the accommodating groove 91, and the copper tube 7 changes from the horizontal direction to the vertical direction.
