[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 2 to 4This utility model provides a technical solution: an automatic tape winding device for PTC chip components, including a worktable 1, a feeding device mounting base 31 on the worktable 1, a tape feeding device 2 rotatably connected to one side of the feeding device mounting base 31, a tape feeding cylinder 4 on the discharge side of the tape feeding device 2, the tape feeding cylinder 4 being a sliding cylinder, the tape feeding cylinder 4 being fixed to the worktable 1 by bolts, and a feeding plate 41 bolted to the output end of the tape feeding cylinder 4, the surface of the feeding plate 41... The feeding plate 41 has a groove, into which the tape is embedded. The movement of the feeding plate 41 drives the tape feeding device 2 to feed the tape, causing the tape roll to rotate and unload. Side plates 5 are fixed on both sides of the feeding plate 41 on the worktable 1. The side plates 5 have round holes, and a rotating shaft is connected to the bearing in the round hole. The first synchronous pulley 51 is sleeved on the rotating shaft. Bolts are connected to the surfaces of the first synchronous pulley 51 and the rotating shaft, so that the first synchronous pulley 51 and the rotating shaft rotate together. Through holes are opened on the end faces of the rotating shaft and the first synchronous pulley 51. A clamping plate 75 is inserted into the through hole. The end of the clamping plate 75 has a clamping groove for placing the PTC chip assembly. The clamping plates 75 at both ends are used to clamp the PTC chip assembly. The extension and retraction of the clamping plates 75 is controlled by a pressure cylinder 71. The clamping plate 75 is first extended to the middle, then the PTC chip assembly is placed between the clamping plates 75 for initial positioning. The PTC chip assembly is then clamped by the clamping plates 75, and adhesive tape is simultaneously adhered to the lower surface of the PTC chip assembly. The feed plate 41 is retracted, and the rotation of the first synchronous pulley 51 is controlled, causing the clamping plate 75 to drive the PTC chip assembly to rotate. In this way, the rotation of the first synchronous pulley 51 causes the insulating tape to be wrapped around the PTC chip assembly. At the same time, the number of rotations is controlled to ensure that the number of tape turns on each PTC chip assembly is the same. In summary, by rotating the first synchronous pulley 51, the clamping plate 75 and the PTC chip assembly rotate together, so that the tape is wrapped around the PTC chip assembly, which improves the tape wrapping efficiency and ensures the consistency of the product.

[0024] A tape tensioning cylinder 3 is fixed to the workbench 1 by bolts. The output end of the tape tensioning cylinder 3 is connected to the feeding device mounting base 31 by bolts. The position of the feeding mounting base 31 is controlled by the extension and retraction of the tape tensioning cylinder 3, which further controls the distance between the tape feeding device 2 and the tape feeding cylinder 4, adjusts the tension on the tape, keeps the tape in a tensioned state, and improves the quality of tape winding.

[0025] like Figure 2 and 4As shown, the tape winding motor 6 is fixed on the workbench 1. The tape winding motor 6 is located on the outside of the side plate 5. The output end of the tape winding motor 6 is connected to the rotating shaft 61 through the coupling 62. The two ends of the rotating shaft 61 extend out of the side plates 5 on both sides. The rotating shaft 61 is rotatably connected to the side plate 5. The two ends of the rotating shaft 61 are also fitted with second synchronous pulleys 52. The rotating shaft 61 and the second synchronous pulleys 52 rotate synchronously. The second synchronous pulleys 52 are connected to the first synchronous pulleys 51 through a synchronous belt. The rotation of the tape winding motor 6 increases the driving force, causing the rotating shaft 61 and the second synchronous pulleys 52 to rotate. The first synchronous pulley 51 is further rotated through the transmission of the synchronous belt, thereby driving the first synchronous pulley 51 to rotate and causing the tape to be wound on the PTC chip assembly.

[0026] The worktable 1 also has a discharge translation cylinder 8 and a product gripping cylinder 81. The product gripping cylinder 81 is fixed on the output end of the discharge translation cylinder 8. The discharge translation cylinder 8 is fixed on one side of the PTC chip assembly. The product gripping cylinder 81 is used to clamp the wound PTC chip assembly. The discharge translation cylinder 8 is used to control the position of the product gripping cylinder 81 so that the wound PTC chip assembly moves to the discharge station.

[0027] A cylinder mounting plate 7 is also fixed to the outer side of the side plate 5. The cylinder mounting plate 7 is fixed to the worktable 1. A pressing cylinder 71 is fixed to the outer surface of the cylinder mounting plate 7. A sleeve 72 is connected to the output end of the pressing cylinder. A roller 74 is inserted into the sleeve 72. The roller 74 can rotate inside the sleeve 72. The roller 74 is connected to the clamping plate 75. A cover plate 73 is fixed to the other end face of the sleeve 72. The roller 74 is set inside the sleeve 72 by the cover plate 73. The extension and retraction of the pressing cylinder 71 controls the extension and retraction of the sleeve 72, so that the roller 74 and the clamping plate 75 extend and retract together to clamp the PTC chip assembly. At the same time, the roller 74 can rotate inside the sleeve 72. Furthermore, the clamping plate 75 can rotate, which facilitates the rotation of the PTC chip assembly for tape winding.

[0028] like Figure 3 As shown, a rectangular hole is provided on the workbench 1, and a lifting cylinder 91 is provided below the rectangular hole. The lifting cylinder 91 is fixed on the lower surface of the workbench 1. A cutting blade 9 is connected to the output end of the lifting cylinder 91. The cutting blade 9 is located on the outside of the clamping plate 75. The tape is cut using the cutting blade 9.

[0029] A clamping groove is provided in the middle part of the end of the clamping plate 75. The clamping groove is used to make way for the wires coming out from the side of the PTC chip assembly, so that the clamping plate 75 can clamp the assembly with wires coming out from one side or the assembly with wires coming out from both sides, thus expanding the applicability of the device.

[0030] like Figure 1As shown, a protective cover 10 is fixed on the workbench 1. The protective cover 10 completely blocks the material discharge process, preventing hair and material debris from sticking to the adhesive surface of the tape and improving product performance.

[0031] The tape wrapping process:

[0032] First, the extension and retraction of the tape feeding cylinder 4 causes the feeding plate 41 to extend, driving the tape to feed. Simultaneously, the clamping plate 75 extends, placing the PTC chip assembly between the clamping plates 75 and clamping it. The feeding plate 41 extends below the clamping plates 75, placing the lower surface of the PTC chip assembly on the tape. Then, the feeding plate 41 retracts, rotating the first synchronous pulley 51, causing the clamping plates 75 and the PTC chip assembly to rotate, thus winding the tape around the PTC chip assembly. After the chip assembly is wrapped, the extension and retraction of the discharge translation cylinder 8 and the product gripping cylinder 81 are controlled to move the PTC chip assembly to one side of the cutting edge 9, so that the tape is above the cutting edge 9. At the same time, the PTC chip assembly to be wrapped with tape is placed between the clamping plates 75 and held by the clamping plates 75. The tape is cut by the cutting edge 9. Finally, the PTC chip assembly is moved to the discharge station by the discharge translation cylinder 8 and the product gripping cylinder 81.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
