Description

Technical Field

[0001] The invention belongs to the technical field of copper wire production and relates to a copper wire pickling device. Background Art

[0002] Tinning of copper wire is a common surface treatment process, which is mainly used to improve the corrosion resistance, welding performance and conductivity of copper wire. The tinning process of copper wire is: wire laying → annealing and softening → pickling → drying → tinning → cooling → wire winding. The pickling process is to use appropriate pickling liquid to clean and activate the copper wire before it enters the tinning furnace to ensure good adhesion between the tin layer and the copper wire, so that the copper wire surface is easier to absorb tin.

[0003] The existing pickling tanks are relatively simple, such as a copper wire pickling device disclosed in a Chinese patent [patent application number 202410715463.X], which includes a pickling tank containing acid liquid; a telescopic frame is arranged on a mounting frame, and changes its own length by self-expansion; a guide frame is arranged at the lower part of the telescopic frame, and the guide frame is driven to enter and exit the acid liquid in the pickling tank through the expansion and contraction of the telescopic frame; the upper and lower ends of the telescopic frame are respectively connected to the mounting frame and the guide frame; the copper wire to be pickled is wound on the guide frame, and enters and exits the acid liquid in the pickling tank together with the guide frame. Since this pickling equipment cannot clean the surface of the copper wire, there is still oil stain attached to the surface of the copper wire, resulting in that the pickling liquid cannot fully contact the surface of the copper wire, and the pickling effect is poor.

[0004] In order to improve the pickling effect of copper wire, remove the attachments on the surface of copper wire, and make the pickling liquid fully contact the surface of copper wire, the Chinese patent discloses a tinned copper wire surface acid cleaning device [patent application number 202210585086.3], which includes a base, a support seat, a cleaning chamber, a first support frame and a salvage mechanism. The cleaning chamber also includes a flow mechanism, which includes a third transmission assembly, a connecting block and an impeller. The rear side of the inner wall of the cleaning chamber is rotatably connected with a connecting block, which is located on the right side of the second rotating shaft. The third transmission assembly is wound around the rear part of the second rotating shaft and the connecting block. An impeller is installed at the front end of the connecting block, and the impeller is located on the rear side of the brush. When the impeller rotates rapidly, the pickling liquid in the cleaning chamber is stirred rapidly, so that the pickling liquid can be fully contacted with the copper wire reel, which is beneficial to improve the pickling efficiency of the copper wire reel and facilitate the tinning of the copper wire reel. However, the flow of the pickling liquid has a weak impact on the copper wire and cannot effectively clean the oil stains and dirt on the copper wire.

[0005] Another example is a Chinese patent that discloses a pickling tank for pretreatment of tin plating on the surface of copper wire [patent application number 202311647642.6]. The pickling tank for pretreatment of tin plating on the surface of copper wire is provided with a rotatable adjustment frame. The reciprocating screw drives the fixed cylinder to rotate, so that the second magnet and the third magnet correspond to the position of the first magnet alternately. The repulsive force and attractive force between the magnets are used to drive the adjustment frame to reciprocate, thereby controlling the copper wire body guided by the lower limit wheel to swing back and forth in the pickling liquid. The copper wire body increases resistance when it swings in the reverse direction in the flowing pickling liquid, and accelerates the falling of oily impurities attached to the copper wire body. However, the amplitude of this reciprocating swing is low, which is not enough to shake off the grapefruit dirt, and the cleaning effect is still poor. Summary of the invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a copper wire pickling device, which uses a vibration component to efficiently remove oil impurities on the copper wire, exposes the surface of the copper wire to the pickling liquid, allows the pickling liquid to fully contact the surface of the copper wire, and has a good pickling effect.

[0007] The purpose of the present invention can be achieved by the following technical solutions: a copper wire pickling device, comprising a pickling box with an upper end opening, a heat-conducting partition is fixed in the pickling box to separate the pickling box into a pickling tank and a heating chamber, and the device is characterized in that a heating plate is fixed on the lower surface of the heat-conducting partition, lead-out brackets are respectively fixed on both sides of the upper end of the pickling box, a guide roller 1 is rotatably connected to the lead-out bracket, two guide rollers 2 are rotatably connected to the bottom of the pickling tank, strip-shaped installation windows are opened on both sides of the pickling box, and a sliding device is provided on the installation window along the A vibration component that makes the copper wire vibrate in the feeding direction of the copper wire, the vibration component includes two translation slide bars and a vibration roller located between two guide rollers, limit blocks are respectively fixed at both ends of the installation window, a sliding shaft is connected between the two limit blocks, the upper end of the translation slide bar is sleeved on the sliding shaft and translates along the sliding shaft, a return spring is sleeved on the sliding shaft, one end of the return spring abuts on the limit block, and the other end abuts on the translation slide bar, the vibration roller is rotatably connected between the two translation slide bars, and a driving mechanism that drives the vibration component to vibrate back and forth is also provided in the pickling tank.

[0008] Furthermore, the driving mechanism includes a motor, a gantry lifting frame and a water-deflecting roller. A linear slide is fixed on the inner wall of the pickling tank. Both sides of the gantry lifting frame are embedded in the linear slide and can slide up and down along the linear slide. The motor is fixed to the upper end of the gantry lifting frame, and the water-deflecting roller is rotatably connected to the lower end of the gantry lifting frame. A horizontal rod is fixed on one side of the translation slide rod, and a force-bearing ball head is fixed on the outer end of the horizontal rod. A plurality of water-deflecting plates are fixed on the roller surface of the water-deflecting roller, and synchronously rotating knocking discs are fixed at both ends of the water-deflecting roller. A plurality of impact rods are evenly distributed circumferentially on the knocking disc, and a billiard ball that can hit the force-bearing ball head is fixed on the outer end of the impact rod. A synchronously rotating driven wheel is also fixed on the shaft of the water-deflecting roller, a driving wheel is fixed on the output shaft of the motor, and leather rings are mounted on the driving wheel and the driven wheel for power transmission. A block that prevents the gantry lifting frame from sliding out of the linear slide is fixed at the bottom of the linear slide.

[0009] The motor drives the water-pumping roller to rotate through the linkage of the driving wheel and the driven wheel. The water-pumping plate on the water-pumping roller pushes the pickling liquid in the pickling tank to the copper wire, and the pickling liquid flushes the surface of the copper wire. At the same time, the water-pumping roller rotates, driving the impact rods to rotate. The impact ball at the front end of the impact rod continuously hits the force-bearing ball head, pushing the horizontal rod, the translation slide rod and the vibration roller backward, and the reset spring restores the horizontal rod, the translation slide rod and the vibration roller to their original positions again and again. The vibration roller scrapes the surface of the copper wire wound thereon while constantly vibrating back and forth. At the same time, due to the movement of the vibration roller back and forth, the travel trajectory of the copper wire also moves up and down, causing the copper wire to continuously cut the liquid surface on the vertical plane in the pickling liquid and collide with the water flow brought by the water-pumping plate, so as to shake off the oil and impurities on the copper wire.

[0010] Furthermore, a mounting plate is fixed on the upper end of the pickling tank, a driving plate is fixed on one side of the gantry lifting frame, a sleeve with an internal thread is fixed on the driving plate, a screw is rotatably connected to the mounting plate, the lower end of the screw is inserted into the sleeve and threadedly connected to the sleeve, and a turntable handle is fixed on the upper end of the screw.

[0011] The upper end of the screw is the optical axis, which is rotatably connected to the mounting plate through the bearing. When the worker turns the turntable handle, the driving plate can be driven up and down. The driving plate drives the gantry lifting frame to slide along the linear slide rail, thereby changing the height position of the water-deflecting roller, adjusting the impact angle and impact force between the billiard ball and the force-bearing ball head, and finally adjusting the amplitude of the vibration roller.

[0012] Furthermore, the guide roller 1 and the vibration roller are both provided with a plurality of annular grooves for limiting the lateral translation of the copper wire.

[0013] Furthermore, three guide rollers are respectively provided at both ends of the opening of the pickling box.

[0014] Furthermore, an L-shaped left support frame is fixed at the left end of the outside of the pickling box, and an L-shaped right support frame is fixed at the right end of the outside of the pickling box. An I-beam is connected between the left support frame and the right support frame, and the bottom of the pickling box is against the I-beam. A horizontal pad is fixed to the lower end of the left support frame, and a roller is connected to the lower end of the right support frame. A concave frame is also rotatably connected to the right support frame.

[0015] The concave frame rotates downward and can contact the ground, lift the roller and make it suspended in the air, so that the pickling box cannot move, avoiding displacement during work. The concave frame rotates upward, so that the roller contacts the ground, and the upper end of the right support frame is pressed down to make the horizontal pad off the ground, which can push the entire pickling box to move and facilitate the transfer of position.

[0016] Furthermore, the upper end of the left support frame has a hand-held portion bent outward, and a recovery tank for collecting pickling liquid is fixed on the hand-held portion. After the copper wire is pulled out of the pickling tank, the pickling liquid remaining on the copper wire is prevented from dripping onto the ground and causing pollution. The recovery tank is installed between the two hand-held portions to facilitate the recovery of the pickling liquid.

[0017] Furthermore, the diameter of the force-bearing ball head is greater than the diameter of the billiard ball.

[0018] Furthermore, the heating plate is built with an electric heating wire, and a power connector electrically connected to the electric heating wire is fixed on the side wall of the pickling box. The power cord is connected to an external power source, and the power cord is inserted into the power connector to energize the electric heating wire to generate heat, and the heating plate transfers the heat to the heat-conducting partition, thereby controlling the temperature of the pickling solution in the pickling tank and keeping the pickling solution within an optimal temperature range.

[0019] Compared with the prior art, this copper wire pickling device has the following advantages:

[0020] 1. The motor-driven swishing roller can not only push the water flow to impact the copper wire, but also drive the impact rod to swing to impact the force-bearing ball head, sharing a power source, saving cost and space; in the process of the vibration roller moving back and forth, the annular groove of the vibration roller rubs back and forth on the surface of the copper wire, which can scrape off most of the oil and impurities on the surface of the copper wire; at the same time, it also drives the copper wire to cut the water flow, and collide with the water flow to clean the oil and impurities attached to the surface of the copper wire. Under the dual action, impurities on the surface of the copper wire are removed, and the cleaning effect is better.

[0021] 2. Since the vibration roller vibrates continuously back and forth instead of left and right, it does not affect the lateral position of the copper wire and always keeps it at the bottom of the annular groove of the vibration roller. During the vibration, the copper wire still keeps moving on the same vertical plane, avoiding the phenomenon of adjacent copper wires jumping and entanglement.

[0022] 3. Workers can turn the turntable handle to adjust the height of the gantry lifting frame and the water-discharging roller by rotating the screw, thereby changing the distance between the billiard ball and the force-bearing ball head, and ultimately adjusting the reciprocating amplitude of the vibration roller.

[0023] 4. This copper wire pickling device is movable. By rotating the concave frame upward and switching the rollers to contact the ground, the entire pickling box can be pushed to move, making it convenient to transfer positions. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] like Figure 1 , Figure 2 , Figure 3As shown, the copper wire pickling device comprises a pickling box 1 with an opening at the upper end, a heat-conducting partition 2 is fixed in the pickling box 1 for dividing the pickling box 1 into a pickling tank 111 and a heating chamber 112, a heating plate 3 is fixed to the lower surface of the heat-conducting partition 2, lead-out brackets 4 are respectively fixed on both sides of the upper end of the pickling box 1, a guide roller 5 is rotatably connected to the lead-out bracket 4, two guide rollers 6 are rotatably connected to the bottom of the pickling tank 111, strip-shaped installation windows 113 are opened on both sides of the pickling box 1, and a vibration component for vibrating the copper wire along the feeding direction of the copper wire is slidably provided on the installation window 113.

[0032] Specifically, if Figure 5 As shown, the vibration assembly includes two translation slide bars 7 and a vibration roller 8 located between two guide rollers 6, and limit blocks 114 are fixed at both ends of the installation window 113. A sliding shaft 115 is connected between the two limit blocks 114. The upper end of the translation slide bar 7 is sleeved on the sliding shaft 115 and translates along the sliding shaft 115. A return spring 116 is sleeved on the sliding shaft 115. One end of the return spring 116 rests on the limit block 114, and the other end rests on the translation slide bar 7. The vibration roller 8 is rotatably connected between the two translation slide bars 7. A driving mechanism for driving the vibration assembly to vibrate back and forth is also provided in the pickling tank 111.

[0033] The guide roller 1 5 and the vibration roller 8 are provided with a plurality of annular grooves 26 for limiting the lateral translation of the copper wire. Only one copper wire is arranged in the annular groove 26 to prevent the copper wire from lateral translation during pickling. Guide rollers 3 27 are respectively arranged at both ends of the opening of the pickling box 1, and the guide rollers 3 27 are used to guide the copper wire to enter or leave the pickling tank 111.

[0034] like Figure 4 As shown, the driving mechanism includes a motor 9, a gantry lifting frame 10 and a water-discharging roller 11. A linear slide rail 117 is fixed on the inner wall of the pickling tank 111. Both sides of the gantry lifting frame 10 are embedded in the linear slide rail 117 and can slide up and down along the linear slide rail 117. The motor 9 is fixed to the upper end of the gantry lifting frame 10. The water-discharging roller 11 is rotatably connected to the lower end of the gantry lifting frame 10. A horizontal rod 12 is fixed to one side of the translation slide rod 7. A force-bearing ball head 13 is fixed to the outer end of the horizontal rod 12. A plurality of water-discharging plates 14 are fixed on the roller surface of the water-discharging roller 11. Synchronously rotating knocking discs 15 are fixed to both ends of the water-discharging roller 11. A plurality of impact rods 16 are evenly distributed circumferentially on the striking disc 15, and a billiard ball 17 that can hit the force-bearing ball head 13 is fixed to the outer end of the impact rod 16. The diameter of the force-bearing ball head 13 is larger than the diameter of the billiard ball 17. The billiard ball 17 squeezes the force-bearing ball head 13 to make it retreat, and the impact rod 16 continues to rotate until the billiard ball 17 passes over the force-bearing ball head 13, and the reset spring 116 drives the translation slide bar 7, the horizontal rod 12 and the force-bearing ball head 13 to reset, and the next impact rod 16 continues to drive the billiard ball 17 to squeeze the force-bearing ball head 13, and so on and so forth, so that the vibration roller 8 continues to vibrate back and forth and scrapes the copper wire thereon.

[0035] A driven wheel 18 that rotates synchronously is also fixed on the shaft of the water-discharging roller 11, a driving wheel 19 is fixed on the output shaft of the motor 9, and a leather ring 20 is mounted on the driving wheel 19 and the driven wheel 18 for power transmission. A block is fixed at the bottom of the linear slide rail 117 to prevent the gantry lifting frame 10 from sliding out of the linear slide rail 117. The motor 9 drives the water-dispensing roller 11 to rotate through the linkage of the driving wheel 19 and the driven wheel 18. The water-dispensing plate 14 on the water-dispensing roller 11 pushes the pickling liquid in the pickling tank 111 to the copper wire, and the pickling liquid flushes the surface of the copper wire. At the same time, the water-dispensing roller 11 rotates, driving the impact rods 16 to rotate. The impact ball 17 at the front end of the impact rod 16 continuously hits the force-bearing ball head 13, pushing the horizontal rod 12, the translation slide bar 7 and the vibration roller 8 backward, and the reset spring 116 restores the horizontal rod 12, the translation slide bar 7 and the vibration roller 8 to their original positions again and again. The vibration roller 8 scrapes the surface of the copper wire wound thereon while constantly vibrating back and forth. At the same time, due to the movement of the vibration roller 8 back and forth, the travel trajectory of the copper wire also moves up and down, so that the copper wire keeps cutting the liquid surface on the vertical plane in the pickling liquid, and collides with the water flow brought by the water-dispensing plate 14, so as to shake off the oil impurities on the copper wire.

[0036] A mounting plate 21 is fixed to the upper end of the pickling tank 111, a driving plate 22 is fixed to one side of the gantry lifting frame 10, a sleeve 23 with an internal thread is fixed to the driving plate 22, a screw rod 24 is rotatably connected to the mounting plate 21, the lower end of the screw rod 24 is inserted into the sleeve 23 and is threadedly connected to the sleeve 23, and a turntable handle 25 is fixed to the upper end of the screw rod 24. The upper end of the screw rod 24 is an optical axis, which is rotatably connected to the mounting plate 21 through a bearing. When a worker rotates the turntable handle 25, the driving plate 22 can be driven to rise and fall, and the driving plate 22 drives the gantry lifting frame 10 to slide along the linear slide rail 117, thereby changing the height position of the water-discharging roller 11, adjusting the impact angle and impact strength of the billiard ball 17 and the force-bearing ball head 13, and finally adjusting the amplitude of the vibration roller 8.

[0037] An L-shaped left support frame 28 is fixed to the left end of the outside of the pickling box 1, and an L-shaped right support frame 29 is fixed to the right end of the outside of the pickling box 1. An I-beam 30 is connected between the left support frame 28 and the right support frame 29. The bottom of the pickling box 1 is against the I-beam 30. A horizontal pad 31 is fixed to the lower end of the left support frame 28, and a roller 32 is connected to the lower end of the right support frame 29. A concave frame 33 is also rotatably connected to the right support frame 29. The concave frame 33 rotates downward and can contact the ground, lift the roller 32, and make the roller 32 suspended in the air, so that the pickling box 1 cannot move, avoiding displacement during work. The concave frame 33 rotates upward, then the roller 32 is switched to contact the ground, and the upper end of the right support frame 29 is pressed down with force to make the horizontal pad 31 separate from the ground, which can push the entire pickling box 1 to move and facilitate the transfer of position.

[0038] The upper end of the left support frame 28 has a hand-held portion 34 bent outward, and a recovery tank 35 for collecting pickling liquid is fixed on the hand-held portion 34. After the copper wire is pulled out of the pickling tank 111, the pickling liquid remaining on the copper wire is prevented from dripping onto the ground and causing pollution. The recovery tank 35 is installed between the two hand-held portions 34 to facilitate the recovery of the pickling liquid.

[0039] The heating plate 3 has an electric heating wire 36 built in, and a power connector 37 electrically connected to the electric heating wire 36 is fixed on the side wall of the pickling box 1. The power line is connected to an external power source, and the power line is inserted into the power connector 37 to energize the electric heating wire 36 for heating. The heating plate 3 transfers the heat to the heat-conducting partition 2, thereby controlling the temperature of the pickling solution in the pickling tank 111, so that the pickling solution is kept within an optimal temperature range.

[0040] Working process: the copper wire enters from the right guide roller 1 5, passes through the right guide roller 3 27, guide roller 2 6 and vibration roller 8, passes through the left guide roller 2 6 and guide roller 3 27, and finally is pulled out from the left guide roller 1 5. Turn the turntable handle 25, adjust the height of the water-dispensing roller 11, start the motor 9, drive the water-dispensing roller 11 to rotate, the water-dispensing plate 14 drives the water to flow to the vibration roller 8, and drives the vibration roller 8 to vibrate back and forth, scraping and shaking off the oil and impurities on the copper wire, facilitating the pickling operation in the second half and improving the pickling effect.

[0041] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
