Description

Technical Field

[0001] The utility model relates to the field of winding machines, in particular to a lead-free solder wire winding machine with adjustable tension force. Background Art

[0002] Lead-free solder wire is a solder used for electronic soldering. Its main component is tin but it does not contain lead. This solder is used to replace the traditional lead-containing solder to reduce the harm to the environment and health. During the production process of lead-free solder wire, it needs to be wound into a winding disc through a winding device to reduce the occupied space and facilitate packaging, transportation and use.

[0003] In the prior art, during the winding process of lead-free solder wire, an appropriate tension force needs to be maintained. If the tension force is too large, the solder wire is likely to break; if the tension force is too small, the winding will be loose, thus affecting the winding effect of the lead-free solder wire. However, it is difficult to adjust the tension force of the lead-free solder wire during the winding process of traditional winding machines, thus affecting the production efficiency of lead-free solder wire. In addition, during the winding process of the winding disc, the lead-free solder wire is likely to accumulate unevenly on the winding disc, forming a winding layer with uneven height. This not only affects the appearance of the winding, but also is likely to cause looseness or knotting during the subsequent processing, seriously affecting the use effect of the lead-free solder wire.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be intermediate components present at the same time.

[0035] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific embodiments.

[0036] As Figures 1 to 5 shown, the embodiment of the present utility model provides a lead-free solder wire winding machine with adjustable tension, including a wire winding disc 1, a wire winding motor 2, a lateral movement mechanism 3, a lifting mechanism 4, a lifting seat 5, a wire winding roller 6, and a wire winding guide roller assembly 7;

[0037] The output shaft of the wire winding motor 2 is connected to the wire winding disc 1, and the wire winding disc 1 is used for winding the lead-free solder wire; by rotating the wire winding disc 1, the lead-free solder wire can be wound on the wire winding disc 1 for easy packaging, transportation, and subsequent use.

[0038] The lifting mechanism 4 is located at the side end of the winding disc 1. The lifting mechanism 4 is connected to the lifting seat 5. The wire winding guide roller assembly 7 and the wire winding roller 6 are both arranged on the lifting seat 5. The lead-free solder wire passes through the wire winding guide roller assembly 7 and the wire winding roller 6 in sequence and winds into the winding disc 1. The lifting mechanism 4 is used to adjust the winding height position between the lead-free solder wire and the winding disc 1. The wire winding guide roller assembly 7 can guide the lead-free solder wire to smoothly enter the wire winding roller 6 along a preset path. The wire winding roller 6 can control the position and direction of the lead-free solder wire entering the winding disc 1, ensuring that the lead-free solder wire can be wound on the winding disc 1 stably and evenly. The lifting mechanism 4 can adjust the relative height between the wire winding roller 6 and the winding disc 1, so that the lead-free solder wire can be wound on the winding disc 1 evenly, avoiding the problem of uneven winding.

[0039] The lateral movement mechanism 3 is connected to the lifting mechanism 4. The lateral movement mechanism 3 is used to adjust the distance between the wire winding roller 6 and the winding disc 1, thereby adjusting the tension of the lead-free solder wire during the winding process, so that the lead-free solder wire maintains an appropriate tension during the winding process, preventing breakage and loosening phenomena, and improving the winding quality and production efficiency.

[0040] As Figure 3 shown, the wire winding guide roller assembly 7 includes a connecting bracket 70, a first wire guide roller 71 and a second wire guide roller 72. The connecting bracket 70 is arranged at the side end of the lifting seat 5. The two first wire guide rollers 71 are horizontally arranged up and down at the end of the connecting bracket 70. The second wire guide roller 72 is arranged between the first wire guide roller 71 and the wire winding roller 6, and the two second wire guide rollers 72 are respectively arranged vertically on the connecting bracket 70. When the lead-free solder wire passes through the first wire guide roller 71 and the second wire guide roller 72, it will be subjected to certain friction and stretching effects, so that the lead-free solder wire is gradually straightened and corrected, avoiding bending and deformation of the lead-free solder wire in different directions.

[0041] As Figure 3 shown, further, a guide wire groove 700 for the lead-free solder wire to pass through is provided in the middle of the first wire guide roller 71 and the second wire guide roller 72. The setting of the guide wire groove 700 can prevent the lead-free solder wire from shifting during the winding process.

[0042] As Figure 1 and Figure 2As shown in the figure, further, the lifting mechanism 4 includes a support base 41, a reduction motor 42, a lead screw 43, a nut seat 44, and a slide rail 45. The support base 41 is connected to the lateral movement mechanism 3. The lead screw 43 is vertically arranged on the support base 41. The output shaft of the reduction motor 42 is connected to the bottom of the lead screw 43. The nut seat 44 is sleeved on the lead screw 43. The nut seat 44 is used to move along the lead screw 43 as the lead screw 43 rotates. The lifting seat 5 is connected to the nut seat 44. Two slide rails 45 are respectively arranged on both sides of the lead screw 43. The lifting seat 5 is movably connected to the slide rail 45 through a slider. The reduction motor 42 can drive the lead screw 43 to rotate, and then drive the nut seat 44 to move up and down along the slide rail 45. Since the lifting seat 5 is connected to the nut seat 44, the lifting adjustment of the lifting seat 5 is realized.

[0043] As Figure 2 shown in the figure, further, the lifting mechanism 4 further includes a first limit inductor 461, a second limit inductor 462, and an induction piece 463. The first limit inductor 461 and the second limit inductor 462 are respectively arranged at the upper and lower ends of the support base 41. Two induction pieces 463 are respectively arranged at the upper and lower ends of the lifting seat 5. The induction piece 463 is used to perform limit induction with the first limit inductor 461 or the second limit inductor 462 as the lifting seat 5 moves up and down. The settings of the first limit inductor 461 and the second limit inductor 462 can limit the lifting movement stroke of the lifting seat 5, and avoid the lifting stroke exceeding the height of the winding disc 1 and affecting the winding effect.

[0044] As Figure 1 and Figure 4 shown in the figure, further, a winding post 10 is arranged in the middle of the winding disc 1. The distance between the first limit inductor 461 and the second limit inductor 462 is equal to the height of the winding post 10. With such a setting, the movement stroke of the lifting seat 5 can be prevented from exceeding the height range of the winding post 10, and the problems of uneven winding or damage to the lead-free solder wire caused by the movement stroke of the lifting seat 5 exceeding the winding area are avoided.

[0045] As Figure 2 shown in the figure, further, a vertical chute 410 is arranged on the support base 41. The first limit inductor 461 and the second limit inductor 462 are located in the vertical chute 410. The setting of the vertical chute 410 can facilitate the operator to move the first limit inductor 461 and the second limit inductor 462 up and down according to the height of the winding disc 1 to meet different winding requirements.

[0046] As Figure 5 shown in the figure, further, the lateral movement mechanism 3 is a linear lead screw module.

[0047] As Figure 1 shown, further, it further includes a first workbench 81 and a second workbench 82. The winding disc 1 is arranged on the first workbench 81, and the transverse moving mechanism 3 is arranged on the second workbench 82. Moving pulleys 800 are respectively arranged at the bottoms of the first workbench 81 and the second workbench 82. With such a setting, the winding machine can be conveniently adjusted in position in the production workshop to quickly change the layout of the equipment according to production requirements and adapt to different working environments and production requirements.
