Abstract
Description
Technical Field
[0001] This utility model relates to the field of filament winding machine technology, specifically to a filament winding machine with a cutting mechanism. Background Technology
[0002] Single-helix filament winding machines play a crucial role in lighting product manufacturing. These machines efficiently wind metal wire onto a core wire according to a predetermined pitch and number of turns, forming the desired single-helix structure. This automated production method significantly improves production efficiency, reduces labor costs, and ensures filament consistency and quality.
[0003] In existing technologies, after a traditional filament winding machine completes the winding of a filament section, it needs to be cut. This cutting process often requires separate operation or manual assistance. During manual cutting, it is difficult to precisely control the cutting length and the smoothness of the cut. If the cutting length deviates too much, it will reduce the compatibility of the filament with the lamp holder and bracket during assembly. If the cut is uneven, it may cause the filament to break or have poor contact during subsequent welding and encapsulation processes, ultimately affecting the performance stability of the electric light source. Furthermore, during manual cutting, operators must be in close contact with the high-speed rotating winding components or sharp cutting tools, posing a safety hazard of cuts.
[0004] This invention proposes a filament winding machine with a cutting mechanism to solve the problem that the cutting process of existing winding machines often needs to be carried out separately or rely on manual assistance. When cutting manually, it is difficult to accurately control the cutting length and cut flatness of the filament. Utility Model Content

[0024] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.
[0025] Example 1: This example provides a filament winding machine with a cutting mechanism, such as... Figure 1 As shown, this invention solves the problem that the cutting process of existing filament winding machines often requires separate operation or manual assistance, and that it is difficult to accurately control the cutting length and cut flatness of the filament during manual cutting. The invention includes a base plate 1, a vertical plate 2 fixedly installed at one end of the top of the base plate 1, a moving structure 3 at the other end of the top of the base plate 1, a winding structure 4 at the upper end between the vertical plate 2 and the moving structure 3, a reciprocating translational structure 5 at the top of the base plate 1, a cutting structure 6 on the side of the vertical plate 2 near the reciprocating translational structure 5, the cutting structure 6 being located between the winding structure 4 and the reciprocating translational structure 5, and a measuring structure 7 on the side of the vertical plate 2 near the winding structure 4, and the measuring structure 7 being located above the winding structure 4.
[0026] Combination Figure 1 and Figure 2 In an embodiment of this utility model, the cutting structure 6 includes an electric push rod 61, which is fixedly inserted inside the vertical plate 2. The telescopic end of the electric push rod 61 is fixedly mounted with a mounting base 62. The mounting base 62 is rotatably connected to a rotating rod 63. A stepper motor 64 is fixedly mounted at the bottom of the mounting base 62 to drive the rotating rod 63 to rotate. A cutting shear 65 is fixedly sleeved on the outside of the rotating rod 63.
[0027] Combination Figure 1 and Figure 2 In an embodiment of this utility model, the cutting structure 6 further includes two sets of guide rods 66, which are respectively fixedly connected to the upper and lower ends of the right end of the mounting base 62. The ends of the two sets of guide rods 66 that are away from the mounting base 62 pass through the vertical plate 2. The surface of the vertical plate 2 is provided with guide holes 67 for cooperating with the guide rods 66.
[0028] Combination Figure 1 and Figure 3 In an embodiment of this utility model, the measuring structure 7 includes a horizontal plate 71, which is fixedly connected to the top of the vertical plate 2 near the center of the bottom plate 1. A laser rangefinder 72 is fixedly connected to the bottom of the horizontal plate 71. A controller is installed at the lower end of one side of the vertical plate 2. The output end of the laser rangefinder 72 is electrically connected to the input end of the controller. The output end of the controller is electrically connected to the input ends of the electric push rod 61 and the stepper motor 64, respectively.
[0029] In use, the filament is wound through the winding structure 4. During the winding process, the horizontal plate 71 measures the geometric parameters such as the length and diameter of the filament and transmits the information to the controller. When the filament length reaches the preset value of the controller, the controller starts the stepper motor 64 and controls the electric push rod 61 to extend. The stepper motor 64 drives the rotating rod 63 to rotate, which in turn drives the cutting shears 65 to rotate. The extension of the electric push rod 61 causes the mounting base 62 to move to the left. The cutting shears 65 then rotate to cut the filament, achieving automatic cutting that is convenient, fast, and precise.
[0030] Example 2: Reference Figure 1 To solve the problem that the winding machine cannot evenly wind the filament, a reciprocating translation structure 5 is provided, including two sets of support plates 51, both of which are fixedly connected to the top of the base plate 1. A one-way threaded column 52 is rotatably connected between the two sets of support plates 51. A servo motor 53 is fixedly installed on the outer side of the right support plate 51 to drive the one-way threaded column 52 to rotate. A threaded sleeve 54 is screwed onto the outer side of the one-way threaded column 52. A guide sleeve 55 is fixedly connected to the top of the threaded sleeve 54. A light rod 56 is fixedly connected to one end of the two sets of support plates 51 near the one-way threaded column 52. A movable sleeve 57 is slidably sleeved on the outer side of the light rod 56. The top of the movable sleeve 57 is fixedly connected to the bottom of the threaded sleeve 54.
[0031] The filament passes through the guide sleeve 55 and is wound around the outside of the winding structure 4. During the winding process, the servo motor 53 is started. When the servo motor 53 is working, it drives the one-way threaded post 52 to rotate. Since the one-way threaded post 52 is threadedly connected to the threaded sleeve 54, and the threaded sleeve 54 slides evenly with the guide rod 56 through the movable sleeve 57, the rotation of the one-way threaded post 52 can drive the threaded sleeve 54 to move left and right. When the threaded sleeve 54 moves left and right, it drives the guide sleeve 55 to move left and right, thereby evenly winding the filament around the outside of the winding structure 4.
[0032] Example 3: Reference Figure 1 and Figure 3 To address the problem of inconvenience in replacing the winding spool 41 in existing winding machines, a movable structure 3 is provided, including an electric telescopic rod 31, which is fixedly installed at the top of the base plate 1 away from the vertical plate 2. A fixed plate 32 is fixedly inserted inside the electric telescopic rod 31. A movable plate 33 is fixedly installed at the telescopic end of the fixed plate 32. A pulley 34 is rotatably installed at the bottom of the movable plate 33. A slide rail 35 is provided on the top of the base plate 1 for sliding cooperation with the pulley 34.
[0033] Combination Figure 1In an embodiment of this utility model, the wire winding structure 4 includes a wire winding spool 41, with connecting blocks 42 fixedly connected to both ends of the wire winding spool 41. A connecting groove 43 is rotatably connected to the top of the vertical plate 2 and the moving plate 33 near the center of the bottom plate 1, for engaging with the connecting blocks 42. A drive motor 44 is fixedly installed on the outer side of the vertical plate 2 for driving the right-end connecting groove 43 to rotate.
[0034] Combination Figure 1 In an embodiment of this utility model, the wire winding structure 4 also includes two locking bolts 45, which are respectively screwed onto the top of the two sets of connecting grooves 43. The top of each of the two sets of connecting blocks 42 is provided with a screw hole 46 for threaded connection with the locking bolts 45.
[0035] When the wire winding spool 41 needs to be replaced, first unscrew the locking bolt 45 from the inside of the screw hole 46 to release the fixing effect of the locking bolt 45 on the connecting block 42. Then, control the electric telescopic rod 31 to retract and drive the moving plate 33 to move to the left. The moving plate 33 drives the pulley 34 to slide inside the slide rail 35, making the moving plate 33 move more smoothly. When the moving plate 33 moves to the left, it drives the left end connecting groove 43 to move until the left end connecting groove 43 separates from the left end connecting block 42. Then, pull the wire winding spool 41 to move to the left, so that the right end connecting groove 43 separates from the right end connecting block 42. Then, replace the wire winding spool 41 with a new one.
[0036] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
