The upper rod body 100 can be inserted into one end of the steel wire tube 200 through the upper rod body feeding assembly 3, and the lower rod body 300 can be inserted into the other end of the steel wire tube 200 through the lower rod body feeding assembly 4. The outer sleeve 400 is sleeved on the outer surfaces of the steel wire tube 200 and the lower rod body 300 through the outer sleeve feeding assembly 7. It also includes a welding electrode 8 arranged on the frame 1 and can slide relative to the frame 1. The welding electrode 8 is located directly above the wire threading platform 2 and can slide close to or away from the wire threading platform 2.

[0028] The present invention, when in use, the steel wire tube 200 is fed to the wire threading platform 2 by the steel wire tube feeding assembly 5, the upper rod body 100 is fed through the upper rod body feeding assembly 3 located on one side of the wire threading platform 2 and inserted into one end of the steel wire tube 200, the sliding welding electrode 8 makes the welding electrode 8 close to the wire threading platform 2, and completes the welding of the upper rod body 100 and the steel wire tube 200, the lower rod body 300 is fed through the lower rod body feeding assembly 4 located on the other side of the wire threading platform 2 and inserted into the other end of the steel wire tube 200, the sliding welding electrode 8 makes the welding electrode 8 close to the wire threading platform 2, and completes the welding of the upper rod body 100 and the steel wire tube 200, The welding electrode 8 is close to the wire threading platform 2 and completes the welding of the lower rod body 300 and the steel wire tube 200. The outer sleeve 400 is then sleeved on the outer surfaces of the steel wire tube 200 and the lower rod body 300 through the outer sleeve feeding assembly 7 to obtain a fuse element product. The product is transported by the wire threading platform 2 and finally transferred to the product receiving box 6 for storage. Therefore, the automatic wire threading machine provided by the present invention can realize the wire threading and assembly of products including more than two components. The entire production process does not require manual operation, has a high degree of automation, and has high production efficiency.

[0029] Combination Figure 2 and Figure 5 As shown, the upper rod feeding assembly 3 includes a feeding box 31 fixedly connected to the frame 1 and a feeding track 33 fixedly connected to the frame 1. The height of the feeding track 33 in the vertical direction is higher than the bottom surface of the feeding box 31. A lifting plate 32 which can slide in the vertical direction is provided at the bottom of one end of the feeding box 31. The sliding lifting plate 32 can make the lifting plate 32 connected to the feeding box 31 or connected to the feeding track 33. A linear propulsion mechanism 34 is provided at one end of the feeding track 33, and a clamping claw 35 which can slide relative to the frame 1 is provided just above the other end. The upper surface of the feeding track 33 has an inwardly recessed guide groove 36. The guide groove 36 can play a guiding role when the upper rod 100 is pushed by the first driving cylinder 37. The linear propulsion mechanism 34 includes a first driving cylinder 37 fixedly connected to the frame 1, and the output shaft of the first driving cylinder 37 is slidably connected in the guide groove 36.

[0030] When in use, the lifting plate 32 slides in the vertical direction to transfer the upper rod body 100 in the feed box 31 to the feed track 33. Since the upper surface of the feed track 33 has an inwardly recessed guide groove 36, the upper rod body 100 falls into the guide groove 36, and the first driving cylinder 37 is started. The output shaft of the first driving cylinder 37 pushes the upper rod body 100 to slide until it is under the clamp 35. The clamp 35 clamps the upper rod body 100 and embeds it into the wire threading mechanism 9. The wire threading mechanism 9 drives the upper rod body 100 to rotate, and embeds the upper rod body 100 into the wire tube 200 during the rotation of the upper rod body 100.

[0031] Preferably, the height of the bottom surface of the feed box 31 in the vertical direction gradually decreases from the end far away from the lifting plate 32 to the end close to the lifting plate 32, so that the automatic feeding of the upper rod body 100 can be achieved by utilizing the height difference.

[0032] like Figure 5 As shown, the upper rod feeding assembly 3 also includes a control assembly 38 that can be pressed on the upper end of the lifting plate 32. The control assembly 38 is connected to the outer wall of the feed box 31. The control assembly 38 can be used to control the feeding rate of the upper rod 100.

[0033] Specifically, the control component 38 includes a second driving cylinder 381 fixedly connected to the outer wall of the feed box 31, a transmission rod 382 drivingly connected to the second driving cylinder 381, and the end of the transmission rod 382 away from the second driving cylinder 381 is rotatably connected to a rocker rod 383, and the rocker rod 383 is fixedly connected to a pressure rod 385 fixedly connected to a pressure block 384, and the pressure rod 385 is rotatably connected to the feed box 31, and rotating the pressure rod 385 can press the pressure block 384 on the lifting plate 32.

[0034] like Figure 3 As shown, the wire threading mechanism 9 includes a clamping mechanism 91 arranged on the frame 1 for clamping the wire tube and a driving rotating mechanism 92 that can move closer to or away from the clamping mechanism 91. The driving rotating mechanism 92 is slidably connected to the frame 1. The clamping mechanism 91 is close to the edge of the wire threading platform 2 so that the wire tube 200 on the wire threading platform 2 can be smoothly clamped into the clamping mechanism 91. The upper rod feeding assembly 3 is connected to the driving rotating mechanism 92 through the clamping claw 35. The present invention is provided with a clamping mechanism 91 for clamping and positioning during the wire threading process, thereby ensuring the stability of the wire tube 200 and the upper rod 100 during the wire threading operation and ensuring the yield rate.

[0035] Specifically, the clamping mechanism 91 includes two sliding jaws 93 that are arranged opposite to each other and can slide relative to each other. The wire tube 200 is located between the two sliding jaws 93. The driving rotation mechanism 92 includes a cylinder 94 fixedly connected to the frame 1 and a motor 96 slidably connected to the frame 1. The cylinder 94 is driven and connected to the motor 96 through a connecting plate 95. The end of the motor 96 close to the clamping mechanism 91 is provided with a driving turntable 97 that can be inserted into the upper rod body 100, and the driving turntable 97 is fixedly connected to the output shaft of the motor 96.

[0036] When in use, the clamping jaws 35 transfer the upper rod body 100 and insert it into the driving turntable 97. The motor 96 drives the driving turntable 97 to rotate, thereby driving the upper rod body 100 to rotate synchronously. The cylinder 94 pushes the motor 96 to slide close to the clamping mechanism 91 by pushing the connecting plate 95. At this time, the wire tube 200 is clamped between the two sliding clamping jaws 93, and the upper rod body 100 completes the wire threading action while rotating.

[0037] like Figure 1 As shown, the lower rod feeding assembly 4 can adopt the same structure as the upper rod feeding assembly 3, and complete the feeding and welding of the lower rod 300 through the same mechanical action. Therefore, the present invention utilizes the wire threading mechanism 9 and the welding electrode 8 to realize the wire threading operation between the upper rod 100 and the steel wire tube 200, and between the steel wire tube 200 and the lower rod 300, thereby ensuring the accuracy of the welding position between the two components.

[0038] The outer sleeve feeding assembly 7 can be just a pneumatic clamp that directly clamps the outer sleeve 400 and is sleeved on the outside of the steel wire tube 200 and the lower rod body 300, or it can be as follows Figure 1 The vibrating plate shown is connected to a discharge pipe, and a negative pressure is provided in the discharge pipe. The outer sleeve 400 is transported through the discharge pipe under the negative pressure, and then transferred and sleeved by the pneumatic clamp, which can ensure the orderliness of the sleeve process.

[0039] Combination Figure 1 and Figure 4 As shown, the wire threading platform 2 includes a shelf plate 21 fixedly connected to the frame 1 and having a plurality of clamping grooves 22 arranged in parallel on the upper surface. One end of the shelf plate 21 is connected to a wire tube feeding assembly 5, and the other end is connected to a product receiving box 6. A push plate 23 is slidably connected to the bottom of the shelf plate 21, which can push the wire tube 200 from one clamping groove 22 to the next adjacent clamping groove 22. The push plate 23 reciprocates in the vertical and horizontal directions to realize the step-by-step pushing of the wire tube 200. A roller assembly 24 is arranged in the clamping groove 22, and the rotation direction of the roller assembly 24 is The roller assembly 24 is perpendicular to the pushing direction of the pushing plate 23, and includes at least two groups of rollers 25 with opposite rotation directions. The same group of rollers 25 is located in the same clamping groove 22. In this way, when the wire tube 200 is pushed into the clamping groove 22 with the rollers 25, it can slide to the left or right side of the shelf plate 21 driven by the rollers 25. A clamping assembly for clamping the wire tube 200 can also be provided on the side of the shelf plate 21. After the wire tube 200 is transported into the clamping assembly by the rollers 25, the clamping assembly clamps the wire tube 200, and then the upper rod body 100 or the lower rod body 300 is embedded and welded.

[0040] The working principle of the present invention is as follows: when in use, the steel wire tube 200 is fed into the clamping groove 22 of the shelf plate 21 by the steel wire tube feeding assembly 5, the pushing plate 23 pushes the steel wire tube 200 one by one according to the clamping groove 22, and the roller 25 pushes the steel wire tube 200 to slide toward the edge of the wire threading platform 2 until the steel wire tube 200 slides into the clamping mechanism 91, and the lifting plate 32 located on one side of the wire threading platform 2 slides in the vertical direction to transfer the upper rod 100 in the feed box 31 to the feed track 33. Since the upper surface of the feed track 33 has an inwardly concave guide The upper rod 100 falls into the guide groove 36, and the first driving cylinder 37 is started. The output shaft of the first driving cylinder 37 pushes the upper rod 100 to slide until it is below the clamping claw 35. The clamping claw 35 transfers the upper rod 100 and inserts it into the driving turntable 97. The motor 96 drives the driving turntable 97 to rotate, thereby driving the upper rod 100 to rotate synchronously. The cylinder 94 pushes the motor 96 by pushing the connecting plate 95 to slide close to the clamping mechanism 91. At this time, the wire tube 200 is clamped between the two sliding clamping claws 93, and the upper rod 100 completes the wire threading action while rotating, slides the welding electrode 8 to make the welding electrode 8 close to the wire threading platform 2, and completes the welding of the upper rod body 100 and the steel wire tube 200. After the welding is completed, the steel wire tube 200 with the upper rod body 100 continues to move under the action of the push plate 23, and is driven by the roller 25 in the opposite direction of the previous rotation, and is transferred to the other side of the wire threading platform 2. The lower rod body 300 is fed through the lower rod body feeding assembly 4 located on the other side of the wire threading platform 2 and inserted into the other end of the steel wire tube 200. The operation steps are the same as those of the upper rod body 1 00, the sliding welding electrode 8 brings the welding electrode 8 close to the wire threading platform 2, and completes the welding of the lower rod body 300 and the steel wire tube 200, and the outer sleeve 400 is then sleeved on the outer surfaces of the steel wire tube 200 and the lower rod body 300 through the outer sleeve feeding assembly 7 to obtain a fuse element product, and the product is finally transferred to the product receiving box 6 for storage through the transportation of the wire threading platform 2. Therefore, the automatic wire threading machine provided by the present invention can realize the wire threading and assembly of products including more than two components. The entire production process does not require manual operation, has a high degree of automation, and has high production efficiency.
