Description

Technical Field

[0001] This utility model relates to the field of copper wire production and processing technology, specifically a wire feeding mechanism for a copper wire processing annealing and tin plating machine. Background Technology

[0002] During the processing of copper wire, an annealing tin plating machine is needed to plate tin on its surface in order to improve the high temperature resistance and corrosion resistance of the copper wire. Existing annealing tin plating machines can operate multiple copper wires simultaneously and at equal intervals for tin plating.

[0003] However, to ensure quality, copper wires currently require cleaning processes such as acid pickling before processing. This necessitates the installation of cleaning tanks and other equipment along the wire's path, increasing costs and extending the wire's travel distance. Overall processing efficiency still has room for improvement. Utility Model Content

[0004] The purpose of this invention is to provide a wire feeding mechanism for a copper wire processing annealing and tin plating machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wire feeding mechanism for a copper wire processing annealing and tin plating machine includes:

[0007] The cleaning structure includes a cleaning box, the inside of which is provided with a liquid box slot, and a first rubber wire port is inserted and embedded on both sides of the liquid box slot. A liquid storage box is installed in the liquid box slot, and a second rubber wire port is inserted and embedded on both sides of the liquid storage box.

[0008] The feeding structure includes a shaft bracket, which is fixedly installed on the lower rear edge of the cleaning box;

[0009] The wire feeding structure is slidably installed on the front side of the cleaning box.

[0010] Furthermore, a base is fixedly installed at the bottom of the cleaning box, and a steering roller is rotatably installed on one side and the upper and lower sides of the second rubber line opening on the rear surface of the cleaning box.

[0011] Furthermore, a cover is fixedly installed at the opening of the liquid storage box by bolts, and a sealing frame is fixedly installed at the bottom of the cover to engage with the opening of the liquid storage box.

[0012] Furthermore, a tray is rotatably mounted on the upper side of the shaft frame via a bearing, a clamping shaft is fixedly mounted on the middle of the upper side of the tray, a winding shaft is sleeved on the side surface of the clamping shaft, and spring locking pins are movably embedded on both sides of the upper end of the clamping shaft.

[0013] Furthermore, the wire feeding structure includes:

[0014] A servo motor is embedded in the bottom of the cleaning box and base.

[0015] A drive shaft is rotatably mounted inside the bottom side of the cleaning box, and the drive shaft and the output end of the servo motor are linked together through a worm gear assembly.

[0016] A bidirectional lead screw is rotatably installed on the inner sides of both ends of the cleaning box. The bidirectional lead screw is linked to the drive shaft through a bevel gear set. Slide seats are screwed onto the upper and lower ends of the bidirectional lead screw.

[0017] Furthermore, the slide is fixedly installed at both ends of the base strip, a linkage shaft is rotatably installed inside the base strip, a pressure roller is fixedly sleeved on the side surface of the linkage shaft, a drive motor is fixedly installed at one end of the upper base strip, and the output end of the drive motor is linked to one end of the linkage shaft through a synchronous sprocket set.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. Copper wire raw material is supplied through the feeding structure. After passing through the cleaning structure, the copper wire is moved forward by the wire feeding structure. Dilute sulfuric acid is injected into the storage box, and the storage box is inserted into the liquid box slot. The copper wire passes through the No. 1 and No. 2 rubber wire openings on both sides and is continuously acid-washed by dilute sulfuric acid before being discharged. Both No. 1 and No. 2 rubber wire openings are made of fluororubber, which can resist the corrosiveness of dilute sulfuric acid. At the same time, the elasticity and shrinkage of the rubber itself maintain the sealing effect at the point where the copper wire passes through, preventing the dilute sulfuric acid from leaking out. This allows for simultaneous wire feeding and cleaning of the copper wire surface. During the copper wire's movement, acid residues and reactant residues on the surface of the copper wire are removed to ensure the quality and effect of subsequent processing steps such as annealing and tin plating.

[0020] 2. The servo motor rotates the transmission shaft under the transmission of the worm gear set, and then drives two bidirectional lead screws synchronously through two sets of bevel gear sets, thereby rubbing each slide to control the two base bars to move closer to each other, so that each pressure roller abuts against the upper and lower sides of the copper wire. After clamping, the drive motor drives the linkage shaft in the upper base bar under the transmission of the synchronous sprocket set, and rotates each pressure roller on the upper side to rub and move simultaneously. The clamping force ensures friction, thereby ensuring the stability of the material supply. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-6 In this embodiment of the present invention, a wire feeding mechanism for a copper wire processing annealing and tin plating machine includes a cleaning structure 1, which includes a cleaning box 101. The cleaning box 101 has a liquid box slot 103 inside, and first rubber wire openings 104 are inserted and embedded on both sides of the liquid box slot 103. A liquid storage box 106 is installed in the liquid box slot 103, and second rubber wire openings 107 are inserted and embedded on both sides of the liquid storage box 106. The feeding structure 2 includes a shaft frame 201, which is fixedly installed on the lower rear edge of the cleaning box 101. The wire feeding structure 3 is slidably installed on the front side of the cleaning box 101.

[0030] Specifically, copper wire raw material is supplied through the feeding structure 2. After passing through the cleaning structure 1, the copper wire is rubbed and moved forward by the wire feeding structure 3. Dilute sulfuric acid is injected into the storage box 106, and the storage box 106 is inserted into the liquid box slot 103. The copper wire passes through the first rubber wire port 104 and the second rubber wire port 107 on both sides and is continuously acid-washed by dilute sulfuric acid before being discharged. The first rubber wire port 104 and the second rubber wire port 107 are both made of fluororubber, which can resist the corrosiveness of dilute sulfuric acid. At the same time, the elasticity and shrinkage of the rubber itself maintain the sealing effect at the point where the copper wire passes through, preventing the dilute sulfuric acid from leaking out. This achieves wire feeding and cleaning of the copper wire surface at the same time, and removes acid residue and reactant residue from the surface of the copper wire during the copper wire's movement, so as to ensure the quality and effect of subsequent annealing, tin plating and other processing steps.

[0031] Example 1

[0032] like Figure 1 As shown, in this embodiment, a base 102 is fixedly installed at the bottom of the cleaning box 101, and a steering roller 105 is rotatably installed on one side and the upper and lower sides of the second rubber line opening 107 on the rear surface of the cleaning box 101; a cover 108 is fixedly installed at the opening of the liquid storage box 106 by bolts, and a sealing frame 109 is fixedly installed at the bottom of the cover 108 to engage with the opening of the liquid storage box 106.

[0033] In this embodiment, the overall device and the support structure are fixed together by the base 102 and bolts. After the acid is filled into the storage box 106, the cover 108 is closed. The sealing effect is ensured by the locking of the sealing frame 109 with the opening on the storage box 106.

[0034] like Figure 4-6 As shown, in this embodiment, a tray 202 is rotatably mounted on the upper side of the shaft frame 201 via a bearing. A clamping shaft 203 is fixedly mounted on the middle of the upper side of the tray 202. A winding shaft 204 is sleeved on the side surface of the clamping shaft 203. Spring locking pins 205 are movably embedded on both sides of the upper end of the clamping shaft 203.

[0035] In practice, the copper wire raw material is wound and stored on the side surface of the winding shaft 204. When the wire feeding structure 3 pulls the copper wire forward, the tray 202 and the clamping shaft 203 drive the winding shaft 204 to rotate for feeding. The supplied wire passes through the middle of the first rubber wire opening 104 and the second rubber wire opening 107 in a relatively vertical state with the cooperation of multiple steering rollers 105. At the same time, the winding shaft 204 and the clamping shaft 203 are sleeved together and clamped on the upper surface of the winding shaft 204 by spring clips 205 for relative positioning and to facilitate the replacement of the winding shaft 204.

[0036] Example 2

[0037] Based on Example 1, in order to supplement the specific method of outputting copper wire through wire feeding structure 3 which was not mentioned in Example 1.

[0038] like Figure 5 As shown, in this embodiment, the wire feeding structure 3 includes: a servo motor 301, embedded in the bottom of the cleaning box 101 and the base 102; a transmission shaft 303, rotatably mounted inside the bottom side of the cleaning box 101, the transmission shaft 303 and the output end of the servo motor 301 being linked together through a worm gear set 302; a bidirectional lead screw 305, rotatably mounted inside both ends of the cleaning box 101, the bidirectional lead screw 305 being linked together with the transmission shaft 303 through a bevel gear set 304, and a slide block 306 being screwed onto the upper and lower ends of the bidirectional lead screw 305; the slide block 306 being fixedly mounted on both ends of the base strip 307, a linkage shaft 308 being rotatably mounted inside the base strip 307, a pressure roller 309 being fixedly mounted on the side surface of the linkage shaft 308, a drive motor 310 being fixedly mounted on one end of the upper base strip 307, and the output end of the drive motor 310 being linked together with one end of the linkage shaft 308 through a synchronous sprocket set 311.

[0039] In practice, the servo motor 301 rotates the transmission shaft 303 under the transmission of the worm gear set 302, and then drives the two bidirectional lead screws 305 synchronously through the two sets of bevel gear sets 304, thereby rubbing each slide 306 to slide, so as to control the two base strips 307 to move closer to each other, so that each pressure roller 309 abuts against the upper and lower sides of the copper wire. After clamping, the drive motor 310 drives the linkage shaft 308 in the upper base strip 307 under the transmission of the synchronous sprocket set 311, and rotates each pressure roller 309 on the upper side to rub and move simultaneously, using the clamping force to ensure friction, thereby ensuring the stability of the material supply.

Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
