Technical Field

[0001] The present invention relates to the technical field of assembly equipment, and particularly to a fixing and combining device for a butterfly wing non-damaging needle. Background Art

[0002] The fixing and combining device for a butterfly wing non-damaging needle is mainly used to safely and stably connect the needle with an infusion tube or a blood collection device, etc., and can effectively fix the position of the needle after connection. The materials are respectively placed on a feeding device, which is usually a device with a conveyor belt or a vibrating disk. Through the uniform conveyance of the conveyor belt or the vibration of the vibrating disk, the butterfly wing non-damaging needle and the infusion tube are orderly conveyed to the assembly station, and the interface of the butterfly wing non-damaging needle is accurately aligned with the connection end of the infusion tube through a mechanical clamp or an automatic alignment device, and the interface of the needle body is slowly inserted into the connection end of the infusion tube through a pushing device. During the assembly process of the needle body and the plastic pipe fitting, due to the influence of plastic raw materials, additives, uneven mixing of raw materials, mold accuracy, mold wear, mold temperature, and injection pressure, etc., there may be some slight differences in the inner wall dimensions of some plastic pipe fittings. Within the tolerance range, there may be dimensional errors, resulting in different insertion difficulties of the needle body. If the inner wall dimension is smaller, the insertion difficulty of the needle body is greater, and the needle body may not be completely inserted into the interior of the plastic pipe fitting. If forced insertion is carried out, the plastic pipe fitting may be deformed, affecting the assembly effect of the needle body and the plastic pipe fitting. For this reason, we propose a fixing and combining device for a butterfly wing non-damaging needle. Summary of the Invention

Detailed implementation mode

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1 Please refer to Figures 1 to 9 , the present invention provides a technical solution: a fixing and combining device for a butterfly wing non-invasive needle, including: the first operating frame 11, an infusion tube 12 is arranged between two groups of the first operating frames 11, and a splint 13 is arranged on the outer wall of the infusion tube 12. A clamping groove 14 is opened on the inner wall of the splint 13. A needle body 15 is inserted into the top of the infusion tube 12. A clamping block 16 is arranged at the top of the needle body 15, and the tail of the clamping block 16 is provided with the second operating frame 17. One end of the second operating frame 17 is slidably connected inside the clamping block 16. When the clamping block 16 drives the needle body 15 to move upward, the end of the second operating frame 17 slides inside the clamping block 16; It further includes: an operating assembly 2, the operating assembly 2 is arranged on the outer wall of the splint 13, and the infusion tube 12 is fixed through the operating assembly 2 to increase the stability of the assembly of the infusion tube 12 and the needle body 15; A monitoring assembly 3, the monitoring assembly 3 is arranged on the top of the clamping block 16, and the extrusion force received by the clamping block 16 is monitored through the monitoring assembly 3 to monitor the insertion difficulty of the needle body 15; An auxiliary assembly 4, the auxiliary assembly 4 is arranged on the outer wall of the pipe orifice of the infusion tube 12 to assist in the assembly operation of the infusion tube 12 and the needle body 15; The heating component 5 is arranged outside the needle body 15. According to the insertion difficulty of the needle body 15 monitored by the monitoring component 3, the heating power of the heating component 5 is adjusted, so as to quickly adjust the heating temperature of the needle body 15, facilitate the softening of the socket end of the infusion tube 12, and reduce the assembly difficulty between the needle body 15 and the infusion tube 12. After the operating component 2 fixes the infusion tube 12, the machine tool controls the second operating frame 17 to work and drives the clamping block 16 to clamp the needle body 15. After clamping the needle body 15, the machine tool controls the second operating frame 17 to rotate until the needle body 15 is at the top of the infusion tube 12, and then controls the second operating frame 17 to move downwards. The second operating frame 17 drives the needle body 15 to move downwards to realize the assembly and docking operation between the needle body 15 and the infusion tube 12. By monitoring the assembly difficulty of the needle body 15 through the monitoring component 3 and adjusting the heating heat of the heating component 5 according to the assembly difficulty, it is convenient for the softening of the socket end of the infusion tube 12, reduces the insertion difficulty of the needle body 15, and improves the assembly efficiency. By heating the physical properties of the material of the infusion tube 12, the force required for the needle to insert into the hose can be significantly reduced. This not only reduces the labor intensity of the operator, but also avoids problems such as the needle body bending, deforming or the hose being damaged due to excessive insertion force. The lower insertion difficulty enables the operator to more accurately control the insertion depth and angle of the needle body, thereby improving the assembly accuracy and ensuring the accurate connection position between the needle body and the hose. Since the insertion process becomes smoother, the operation time extension and product scrapping caused by difficult insertion are reduced, thereby improving the overall production efficiency and reducing the production cost. A reasonable heating temperature can make the hose material deform uniformly during the insertion process, avoiding material damage caused by local stress concentration. This helps to improve the durability and reliability of the product and reduce the possibility of problems such as leakage or connection loosening during use.

[0019] The operating component 2 includes a first connecting frame 21 and a second connecting frame 22 fixed on both sides of the surface of the clamping plate 13. A guiding rod 23 is inserted inside the first connecting frame 21, and a screw rod 24 is threadedly connected inside the second connecting frame 22. The end face of the screw rod 24 is fixedly connected to the output shaft of the motor 25. The outer walls of the guiding rod 23 and the screw rod 24 are both rotatably connected to a first support frame 26, and the bottom of the first support frame 26 is fixed on the surface of the first operating frame 11, which is convenient for clamping and fixing the placed infusion tube 12, making the docking and insertion of the needle body 15 and the infusion tube 12 more stable and improving the stability of the assembly.

[0020] After the infusion tube 12 moves between the two clamping plates 13, the motor 25 works to drive the screw rod 24 to rotate. When the screw rod 24 rotates, under the cooperation of the internal thread of the second connecting frame 22, the two second connecting frames 22 move closer to each other. The second connecting frame 22 drives the clamping plate 13 to move synchronously. The clamping plate 13 drives the first connecting frame 21 to move synchronously. The first connecting frame 21 moves on the outer wall of the guiding rod 23. After the second connecting frame 22 drives the clamping plate 13 to move synchronously, the clamping groove 14 presses against the outer wall of the infusion tube 12 to realize the clamping and fixing operation of the infusion tube 12.

[0021] The monitoring component 3 includes a pressure-bearing plate 31 pressing against the top of the clamping block 16, and a sliding rheostat 32 is fixed to the top of the pressure-bearing plate 31. A first spring 33 is sleeved outside the sliding rheostat 32, and a fixing plate 35 is fixed to the top of the first spring 33. The movement of the pressure-bearing plate 31 drives the sliding rheostat 32 to move synchronously. At the same time, the first spring 33 is in a compressed and energy-storing state. The degree of extrusion force on the pressure sensor 38 by the first spring 33 is used to judge the difficulty of inserting the needle body 15 into the infusion tube 12. The greater the pushing force for inserting the needle body 15 into the interior of the infusion tube 12, the greater the extrusion force on the first spring 33, and the greater the judged difficulty of inserting the needle body 15 into the interior of the infusion tube 12, realizing the monitoring operation of the insertion difficulty of the needle body 15.

[0022] The outer wall of the fixing plate 35 is fixed to the inner wall of the protective sleeve 34, and a third connecting frame 39 is fixed to the outer wall of the protective sleeve 34, and the third connecting frame 39 is connected to the second operating frame 17, realizing the shielding and protection operation of the pressure sensor 38.

[0023] A connecting ring 36 is fixed to the bottom of the fixing plate 35, and a sliding piece 37 is arranged on the inner wall of the connecting ring 36. The sliding piece 37 is slidably connected to the surface of the sliding rheostat 32. A pressure sensor 38 is fixed to the top of the fixing plate 35, and the pressure sensor 38 is fixed to the inner wall of the protective sleeve 34. By the movement of the sliding piece 37 on the surface of the sliding rheostat 32, the change of the resistance value is realized. The change of the resistance value controls the heating power of the heating resistance wire 57. The degree of extrusion force on the pressure sensor 38 by the first spring 33 is used to judge the docking condition between the needle body 15 and the infusion tube 12. When the pressure sensor 38 monitors a change in pressure, the signal is transmitted to the controller. After the signal is transmitted to the controller, the heating resistance wire 57 is powered on, and the heating resistance wire 57 starts to work, realizing the monitoring operation of the docking condition between the needle body 15 and the infusion tube 12.

[0024] When the clamping block 16 needs to drive the needle body 15 to dock with the infusion tube 12, the protective sleeve 34 is pushed. The protective sleeve 34 indirectly pushes the clamping block 16, so that the clamping block 16 drives the clamped needle body 15 to dock with the infusion tube 12. During the docking and insertion process, the clamping block 16 presses against the pressure-bearing plate 31. During the assembly process, the insertion difficulty of the needle body 15 is proportional to the pushing force of the clamping block 16. The greater the insertion difficulty of the needle body 15, the greater the pressing force of the needle body 15 against the clamping block 16, so that the greater the pressing force of the clamping block 16 against the pressure-bearing plate 31. The pressure-bearing plate 31 moves inside the protective sleeve 34, and the pressure-bearing plate 31 drives the sliding rheostat 32 to move synchronously. At this time, the first spring 33 is in a compressed and energy-storing state. The greater the pressing force of the needle body 15 against the clamping block 16, the greater the compression degree of the first spring 33. When the sliding rheostat 32 moves, the sliding piece 37 moves on the surface of the sliding rheostat 32, realizing the change of the resistance value of the sliding rheostat 32. The greater the insertion difficulty of the needle body 15, the smaller the adjusted resistance value of the sliding rheostat 32.

[0025] The auxiliary component 4 includes a support frame 41 fixed on the surface of the splint 13, and a connecting block 42 is fixed on the surface of the support frame 41, and a heating ring 43 is fixed on the surface of the connecting block 42. The heating ring 43 is used to auxiliary heat the plug end of the infusion tube 12 to soften the plug end of the infusion tube 12, thereby facilitating the insertion and docking of the needle body 15 and the infusion tube 12.

[0026] An extraction member 44 is fixed to the top of the heating ring 43, and an extraction cylinder 45 is provided on the side of the extraction member 44. The extraction cylinder 45 is arranged on the top of the plug end of the infusion tube 12. When the monitoring component 3 detects that the insertion of the needle body 15 is difficult, it is judged that there is a possibility that debris blocks the plug end of the infusion tube 12. At this time, the controller receives a signal and controls the extraction cylinder 45 to start working. The negative pressure suction force generated by the extraction member 44 extracts the debris inside the infusion tube 12 through the extraction cylinder 45. If the debris is extracted, the difficulty of inserting the needle body 15 into the infusion tube 12 is reduced.

[0027] Embodiment 2 The heating assembly 5 includes a support frame three 51 fixed on the surface of the operating frame one 11, a heating ring 52 is fixed between two groups of support frames three 51, and the needle body 15 passes through the heating ring 52 to facilitate the heating operation of the needle body 15.

[0028] The inner wall of the heating ring 52 is provided with a slot 53 , and the inner wall of the slot 53 is rotatably connected to a rotating plate 54 , a conduction block 55 is fixed to the bottom of the rotating plate 54 , and the conduction block 55 is pressed against the surface of the needle body 15 to achieve heat conduction, thereby facilitating heating of the needle body 15 .

[0029] A spring 2 56 is fixed to the lower end of the surface of the rotating plate 54, and the end face of the spring 2 56 is fixed to the inner wall of the slot 53. A heating resistor 57 is fixed to the upper end of the surface of the rotating plate 54. During the docking process between the needle body 15 and the infusion tube 12, the needle body 15 presses against the conduction block 55, pushing the conduction block 55 to move away from the needle body 15. The conduction block 55 drives the rotating plate 54 to rotate. At this time, the spring 2 56 is in a compressed and force-storing state. The heat generated by the heating resistor 57 is transmitted to the conduction block 55 through the rotating plate 54. The conduction block 55 presses against the needle body 15 to transmit the heat to the needle body 15, thereby achieving the purpose of heating the needle body 15.

[0030] The smaller the resistance value after adjustment of the sliding rheostat 32, the greater the circuit power, which makes the heating power of the heating resistor wire 57 greater, making it easier to quickly provide heat to the needle body 15, heat the needle body 15, and transfer the heat to the bottom of the needle body 15. After the needle body 15 is heated, the needle body 15 softens the socket end of the infusion tube 12. After the socket end of the infusion tube 12 is softened, it is easier to insert the needle body 15, reducing the difficulty of inserting the needle body 15.
