Description

Technical Field

[0001] The invention relates to the technical field of metal wire processing, in particular to a device for removing an oxide layer on the surface of a tin wire. Background Art

[0002] In the field of electronic manufacturing, tin wire is a core welding material, and its performance is directly related to product quality. However, tin wire is very easy to oxidize in the natural environment, and the oxide layer formed on the surface becomes a key problem that hinders the improvement of welding quality.

[0003] For example, a Chinese patent with the announcement number CN216030021U discloses a device for removing the oxide layer on the surface of a metal wire, including a chassis and a grinding box, wherein a material storage box and a slag collection box are arranged inside the chassis, a reel roller is arranged on one side of the top surface of the chassis through a first bracket, and a reel roller is arranged on the other side of the top surface of the chassis through a second bracket, and a spray chamber is provided between the partitions symmetrically arranged on the inner wall of the grinding box, one side of the partition is the first grinding chamber, and the other side of the partition is the second grinding chamber, a first grinding roller is arranged in the first grinding chamber through a clamping plate, and a second grinding roller is arranged in the second grinding chamber through a clamping plate. By respectively setting a rough grinding roller and a fine grinding roller, the metal wire mesh can be polished twice when in use, and by setting a spray chamber between the first grinding chamber and the second grinding chamber, the outer side of the wire mesh can be sprayed with a grinding and rust removal agent, thereby better improving the removal efficiency of the oxide layer of the metal wire mesh.

[0004] However, the above-mentioned device for removing the oxide layer on the surface of the metal wire cannot adjust the grinding stroke of the metal wire, and the oxide layer thickness of different metal wires may be different. Some may be only slightly oxidized, while others may be severely oxidized. The inability to adjust the stroke means that it is difficult to accurately control the grinding amount for different oxidation degrees. This may cause the slightly oxidized metal wire to be over-grinded, affecting the surface accuracy and performance of the metal wire, while the severely oxidized metal wire will not be completely removed due to insufficient grinding.

[0020] 1. Through the design of the first motor, the first transmission wheel, the rotating column, the grinding disc, the gear, the pushing mechanism and the traction mechanism, when grinding the oxide layer on the surface of the tin wire, the tin wire can be wound around the surface of the traction mechanism, and then the tin wire is inserted from the outer surfaces of the two sets of grinding discs in the form of u and n, and the tin wire inserted from the two sets of grinding discs is wound around the outer surface of the other set of traction mechanisms, so that the two sets of traction mechanisms can rotate clockwise, and the traction mechanism can loosen and reel the tin wire, and in the process of loosening and reeling the tin wire, the tin wire can be passed through the two sets of grinding discs and polished, and then the first motor can be started to drive the first transmission belt to drive the first transmission wheel The first transmission wheel drives the grinding disc at one end of the rotating column to rotate counterclockwise, and the rotating column is driven to rotate by the gear fixed on the outer surface to drive the gear fixed on the outer surface of the other set of rotating column to rotate relatively, so that the two sets of rotating columns can drive the two sets of grinding discs to rotate synchronously and relatively, and the tin wire can pass through the two sets of grinding discs in a clockwise direction. The two sets of grinding discs can grind and remove the surface oxide layer of the tin wire passing through the outer surface through relative rotation. This relative motion increases the relative friction speed between the grinding disc and the tin wire, and can remove the oxide layer more quickly than the traditional single The directional grinding method greatly improves the grinding efficiency and reduces the time required for grinding. When the tin wire passes through the outer surface of the grinding disc in the form of U, the upper half of the outer surface of the tin wire will touch the outer surface of the grinding disc. Then, after passing through the outer surface of another set of grinding discs in the form of N, the lower half of the outer surface of the tin wire will touch the outer surface of another set of grinding discs, so that the outer surface of the tin wire passing through the two sets of grinding discs can be fully polished. This method ensures that the entire circumferential surface of the tin wire can be polished, avoiding grinding dead corners, so that the oxide layer on the surface of the tin wire is fully removed, ensuring the integrity and uniformity of the grinding effect, and making the tin wire more uniform after grinding. The tin wire is rolled up on the outer surface of the traction mechanism, and before grinding the tin wire, the staff can start the traction mechanism installed on the surface of the pushing mechanism to rotate upward or downward, so that the pushing mechanism can push or pull the tin wire on the outer surface of the traction mechanism to break away from the contact of one section from the outer surface of the grinding disk, or increase the contact of one section, so as to reduce or increase the stroke of the tin wire being ground by the grinding disk, so that the device can adapt to tin wires with different degrees of oxidation. For tin wires with a lighter degree of oxidation, the grinding stroke can be appropriately shortened to reduce unnecessary grinding and improve production efficiency. For tin wires with severe oxidation, the grinding stroke can be increased to ensure that the oxide layer is completely removed.

[0021] 2. Through the design of the electric push rod, the mounting plate and the traction mechanism, before grinding the tin wire, the staff can start the electric push rod to push or pull the mounting plate to drive the surface-mounted traction mechanism to rotate upward or downward, so that the mounting plate can push or pull the tin wire on the outer surface of the traction mechanism to break away from the contact of one section from the outer surface of the grinding disc, or increase the contact of one section, so as to reduce or increase the stroke of the tin wire being ground by the grinding disc, and avoid problems such as scratches, thinning or deformation of the tin wire surface caused by excessive grinding, so that it can adapt to the grinding needs of tin wires in different batches and states, and improve the adaptability and resilience of production.

[0022] 3. Through the design of the second motor, the connecting column, the driving wheel, the rotating shaft and the reel, when grinding the oxide layer on the surface of the tin wire, the tin wire can be firstly wound on the outer surface of the reel at the upper end, and then the tin wire is firstly set on the outer surface of the driving wheel in the form of n, and then the tin wire is inserted from the outer surfaces of the two sets of grinding discs in the form of u and n and then set on the outer surface of the other set of driving wheels in the form of u, and fixedly connected to the outer surface of the other set of reels at the lower end, and then the second motor can be started to drive the third transmission belt set on the outer surface of the output shaft to drive the third transmission wheel on the outer surface of the connecting column to rotate, so as to drive the connecting column on the bearing The seat rotates inside, so that the connecting column can drive a driving wheel fixed at one end to pull the tin wire on the outer surface, and the connecting column will drive the fourth driving belt drive shaft through the fifth driving wheel on the outer surface to rotate during the rotation process, so that the shaft can drive the wound tin wire on the outer surface to loosen and let the driving wheel to pull and transport it. In the process of this reel loosening the tin wire, another set of rotating driving wheels and reels will pull and reel the released tin wire, so that the upper and lower halves of the outer surface of the tin wire can be polished by two sets of relatively rotating grinding discs to remove the surface oxide layer during the loosening and reeling process.

[0032] like Figure 1-Figure 4 As shown, this embodiment provides a device for removing the oxide layer on the surface of tin wire, comprising: a housing 1 and two groups of rotating columns 102, the two groups of rotating columns 102 are rotatably installed in the housing 1, a first motor 104 is fixedly installed at one end of the housing 1, a first transmission belt 105 is sleeved on the outer surface of the output shaft of the first motor 104, the other end of the first transmission belt 105 is sleeved on the outer surface of the first transmission wheel 103, the first transmission wheel 103 is fixedly installed on the outer surface of one group of rotating columns 102, and the other ends of the two groups of rotating columns 102 are rotated out from the other end of the housing 1, and a grinding disc 101 is fixedly installed on the outer surface of the rotating column 102 that is rotated out, and the wheel surface of the two groups of grinding discs 101 has an embedded arc ring groove;

[0033] Among them, the two ends of the housing 1 are rotatably installed with pushing mechanisms 2 in opposite shapes, and the traction mechanisms 3 are fixedly installed on the upper surface of one group of the two pushing mechanisms 2 and the lower surface of the other group, and the outer surface of one group of the traction mechanisms 3 is wound with tin wire, so that the tin wire is inserted from the outer surfaces of the two groups of grinding discs 101 in the form of u and n, and the tin wire inserted from the two groups of grinding discs 101 is wound on the outer surface of the other group of traction mechanisms 3, so that the two groups of traction mechanisms 3 can drive the tin wire clockwise to loosen and reel;

[0034] Among them, the two sets of pushing mechanisms 2 installed in opposite rotation can respectively drive the traction mechanism 3 to rotate upward or downward, so that the pushing mechanism 2 can push or pull the tin wire on the outer surface of the traction mechanism 3 to break away from the contact of a segment from the outer surface of the grinding disk 101, or increase the contact of a segment, so as to reduce or increase the stroke of the tin wire being ground by the grinding disk 101. Gears 106 are fixedly installed on the outer surfaces of the two sets of rotating columns 102, and the two sets of gears 106 are meshed, so that the two sets of grinding disks 101 can be synchronously driven to rotate relative to each other.

[0035] Through the design of the first motor 104, the first transmission wheel 103, the rotating column 102, the grinding disc 101, the gear 106, the pushing mechanism 2 and the traction mechanism 3, when grinding the oxide layer on the surface of the tin wire, the tin wire can be wound around the outer surface of the traction mechanism 3, and then the tin wire is inserted from the outer surface of the two groups of grinding discs 101 in the form of u and n, and the tin wire passed through the two groups of grinding discs 101 is wound around the outer surface of the other group of traction mechanism 3, so that the two groups of traction mechanisms 3 can rotate clockwise, and the traction mechanism 3 can loosen and reel the tin wire, and in the process of loosening and reeling the tin wire, the tin wire can be passed through the two groups of grinding discs 101 and polished, and then the first motor 104 can be started to drive the first transmission belt 1 05 drives the first transmission wheel 103 to rotate counterclockwise, so that the first transmission wheel 103 can drive the grinding disc 101 at one end of the rotating column 102 to rotate counterclockwise, and the rotating column 102 will be driven to rotate through the gear 106 fixedly installed on the outer surface to drive the gear 106 fixedly installed on the outer surface of the other set of rotating columns 102 to rotate relatively, so that the two sets of rotating columns 102 can drive the two sets of grinding discs 101 to rotate synchronously and relatively, so that the tin wire can pass through the two sets of grinding discs 101 clockwise. In the process, the two sets of grinding discs 101 will grind the tin wire passing through the outer surface to remove the surface oxide layer through relative rotation. This relative movement increases the relative friction between the grinding disc 101 and the tin wire. The rubbing speed is high, and the oxide layer can be removed more quickly. Compared with the traditional single-direction grinding method, the grinding efficiency is greatly improved, and the time required for grinding is reduced. When the tin wire passes through the outer surface of the grinding disk 101 in the form of a U, the upper half of the outer surface of the tin wire will touch the outer surface of the grinding disk 101, and then after passing through the outer surface of another set of grinding disks 101 in the form of an n, the lower half of the outer surface of the tin wire will touch the outer surface of another set of grinding disks 101, so that the outer surface of the tin wire passing through the two sets of grinding disks 101 can be fully polished. This method ensures that the entire circumferential surface of the tin wire can be polished, avoiding grinding dead corners, so that the oxide layer on the surface of the tin wire is fully removed, ensuring the grinding effect. Integrity and uniformity, the polished tin wire is rolled up on the outer surface of the traction mechanism 3, and before polishing the tin wire, the staff can start the upward or downward rotation of the traction mechanism 3 installed on the surface of the pushing mechanism 2, so that the pushing mechanism 2 can push or pull the tin wire on the outer surface of the traction mechanism 3 from the outer surface of the polishing disk 101 to break away from a segment of contact, or increase a segment of contact, so as to reduce or increase the stroke of the tin wire being polished by the polishing disk 101, so that the device can adapt to tin wires with different degrees of oxidation. For tin wires with a lighter degree of oxidation, the polishing stroke can be appropriately shortened to reduce unnecessary polishing and improve production efficiency. For tin wires with severe oxidation, the polishing stroke can be increased to ensure that the oxide layer is completely removed.

[0036] like Figure 5 As shown, the pushing mechanism 2 includes two sets of mounting plates 202, which are mounted at both ends of the casing 1 in opposite rotations. The upper and lower halves of the two ends of the casing 1 are respectively rotatably mounted with electric push rods 201, and the piston rods of the two sets of electric push rods 201 are respectively rotatably mounted on the upper and lower surfaces of the mounting plates 202 and fixedly mounted in the docking plate 203.

[0037] The two sets of electric push rods 201 can push the two sets of mounting plates 202 to rotate upward or downward, and then the two sets of mounting plates 202 can respectively drive the traction mechanism 3 to rotate upward or downward, and then the mounting plates 202 can push or pull the tin wire on the outer surface of the traction mechanism 3 to break away from the contact of a section from the outer surface of the grinding disc 101, or increase the contact of a section.

[0038] Through the design of the electric push rod 201, the mounting plate 202 and the traction mechanism 3, before grinding the tin wire, the staff can start the electric push rod 201 to push or pull the mounting plate 202 to drive the surface-mounted traction mechanism 3 to rotate upward or downward, so that the mounting plate 202 can push or pull the tin wire on the outer surface of the traction mechanism 3 to break away from the contact of a section from the outer surface of the grinding disk 101, or increase the contact of a section, so as to reduce or increase the stroke of the tin wire being ground by the grinding disk 101, and avoid problems such as scratches, thinning or deformation of the tin wire surface caused by excessive grinding, so that it can adapt to the grinding needs of tin wires in different batches and states, and improve the adaptability and resilience of production.

[0039] like Figure 6-Figure 7 As shown, the traction mechanism 3 includes two groups of connecting plates 301, and the two groups of connecting plates 301 are respectively fixedly mounted on the upper surface of one group of mounting plates 202 and the lower surface of the other group of mounting plates 202, and the upper and lower surfaces of the two groups of connecting plates 301 are respectively fixedly mounted with the second motor 302, the outer surface of the output shaft of the second motor 302 is sleeved with a third transmission belt 312, the other end of the third transmission belt 312 is sleeved on the outer surface of the third transmission wheel 311, and a connecting column 304 is fixedly mounted at one end of the third transmission wheel 311, and the connecting column 304 is rotatably mounted in a bearing seat 313, the bearing seat 313 is fixedly mounted on the mounting plate 202, and a driving wheel 305 is fixedly mounted on the outer surface of the connecting column 304.

[0040] Among them, a V-shaped ring groove is opened on the outer surface of the driving wheel 305, and an anti-slip rubber strip 314 is arranged in the V-shaped ring groove of the driving wheel 305. A U-shaped frame 303 is fixedly installed at one end of the connecting plate 301, and a rotating shaft 306 is rotatably installed at one end of the U-shaped frame 303. A reel 307 is inserted on the outer surface of the rotating shaft 306, and a fourth transmission wheel 310 is fixedly installed on the outer surface of the rotating shaft 306. A fourth transmission belt 309 is sleeved on the outer surface of the fourth transmission wheel 310, and the other end of the fourth transmission belt 309 is sleeved on the outer surface of the fifth transmission wheel 308. The fifth transmission wheel 308 is fixedly installed on the outer surface of the connecting column 304, and the fourth transmission belt 309 is located in the U-shaped frame 303.

[0041] Among them, the outer surface of the reel 307 at the upper end is rolled up with tin wire, and then the tin wire is first put on the outer surface of the driving wheel 305 in the form of n, and then the tin wire is inserted from the outer surfaces of the two groups of grinding discs 101 in the form of u and n and is then put on the outer surface of another group of driving wheels 305 in the form of u, and is fixedly connected to the outer surface of another group of reels 307 at the lower end. The two groups of reels 307 can loosen and reel the tin wire respectively, and then the two groups of grinding discs 101 can grind the upper and lower halves of the outer surface of the tin wire to remove the surface oxide layer during the loosening and reeling process.

[0042] Through the design of the second motor 302, the connecting column 304, the driving wheel 305, the rotating shaft 306 and the reel 307, when grinding the oxide layer on the surface of the tin wire, the tin wire can be firstly wound on the outer surface of the reel 307 at the upper end, and then the tin wire is firstly sleeved on the outer surface of the driving wheel 305 in the form of n, and then the tin wire is inserted from the outer surfaces of the two groups of grinding discs 101 in the form of u and n and then sleeved on the outer surface of the other group of driving wheels 305 in the form of u, and fixedly connected to the outer surface of the other group of reels 307 at the lower end, and then the second motor 302 can be started to drive the third transmission belt 312 sleeved on the outer surface of the output shaft to drive the third transmission wheel 311 on the outer surface of the connecting column 304 to rotate, so as to drive the connecting column 304 to rotate. The bearing seat 313 rotates, so that the connecting column 304 can drive the driving wheel 305 fixed at one end to pull the tin wire on the outer surface, and the connecting column 304 will drive the fourth driving belt 309 to drive the rotating shaft 306 to rotate through the fifth driving wheel 308 on the outer surface during the rotation, so that the rotating shaft 306 can drive the wound tin wire on the outer surface to loosen and let the driving wheel 305 to pull and transport it. In the process of this reel 307 loosening the tin wire, another set of rotating driving wheels 305 and reel 307 will pull and reel the released tin wire, so that the upper and lower halves of the outer surface of the tin wire can be polished by two sets of relatively rotating grinding discs 101 to remove the surface oxide layer during the loosening and reeling process.

[0043] In this embodiment, in order to more clearly describe the relationship between the controlled grinding stroke and the oxidation degree of the tin wire, a linear function can be introduced to establish the connection between the two, as follows:

[0044] Assume that the oxidation degree of the tin wire is x (the value range can be set according to the actual situation, for example, 0≤x≤10, where 0 means no oxidation and 10 means the most severe oxidation), and the grinding stroke is y (the unit can be a length unit such as millimeter), the following linear function can be established:

[0045] y=kx+b; k is the slope, which represents the influence coefficient of oxidation degree on grinding stroke; b is the intercept, which represents the basic grinding stroke when the oxidation degree is 0.

[0046] Example:

[0047] Suppose that it is determined through experiments that k=2, b=10, that is, the function is y=2x+10.

[0048] When the oxidation degree of the tin wire is x=2 (mild oxidation), substituting it into the function yields: y=2x2+10=14 (mm). At this time, the grinding stroke calculated according to the function is 14 mm.

[0049] When the oxidation degree of the tin wire is x=8 (severe oxidation), substituting it into the function yields: y=2x8+10=26 (mm). At this time, the grinding stroke is 26 mm.

[0050] Technical effect:

[0051] Precisely control the grinding stroke: By establishing a functional relationship, the required grinding stroke can be accurately calculated according to the oxidation degree of the tin wire, avoiding blind grinding and improving the accuracy and efficiency of grinding.

[0052] Adapt to different oxidation degrees: For tin wires with different oxidation degrees, the grinding stroke can be automatically adjusted to ensure that the oxide layer is completely removed while reducing excessive grinding of the tin wire and protecting the surface quality of the tin wire.

[0053] Improve production efficiency: Reasonably adjust the grinding stroke according to the degree of oxidation. For tin wire with a lighter degree of oxidation, the grinding time can be shortened, thereby improving the overall production efficiency.

[0054] Easy to operate and manage: The staff can quickly calculate the appropriate grinding stroke by measuring the oxidation degree of the tin wire, which is easy to operate and manage, and is also conducive to the automatic control of the equipment.

[0055] By introducing the above linear function, the working process of the device for removing the oxide layer on the surface of the tin wire can be better quantified and controlled, thereby improving the performance and production efficiency of the device.

[0056] The working steps of this scheme are summarized and sorted out according to the above technical scheme: when grinding the oxide layer on the surface of the tin wire, the tin wire can be firstly wound around the outer surface of the reel 307 at the upper end, and then the tin wire is firstly sleeved on the outer surface of the driving wheel 305 in the form of n, and then the tin wire is inserted from the outer surfaces of the two sets of grinding discs 101 in the form of u and n and then sleeved on the outer surface of another set of driving wheels 305 in the form of u, and fixedly connected to the outer surface of another set of reels 307 at the lower end, and then the second motor 302 can be started to drive the third transmission belt 312 sleeved on the outer surface of the output shaft to drive the third transmission wheel 311 on the outer surface of the connecting column 304 to rotate, so as to drive the connecting column 304 to rotate in the bearing seat 313, and then The connecting column 304 can drive the driving wheel 305 fixed at one end to pull the tin wire on the outer surface, and the connecting column 304 will drive the fourth driving belt 309 to drive the rotating shaft 306 to rotate through the fifth driving wheel 308 on the outer surface during the rotation, so that the rotating shaft 306 can drive the wound tin wire on the outer surface to loosen and let the driving wheel 305 to pull and transport it. During the process of the reel 307 loosening the tin wire, another set of rotating driving wheels 305 and reel 307 will pull and reel the loosened tin wire, so that the tin wire can pass through the two sets of grinding discs 101 during the loosening and reeling process. Before the tin wire is driven, the staff can start the electric push rod 201 to push or pull the mounting plate 202 to drive the connecting plate 30 The driving wheel 305 rotatably mounted on the surface of the driving wheel 305 rotates upward or downward, so that the mounting plate 202 can push or pull the tin wire on the outer surface of the driving wheel 305 to break away from the contact of a section from the outer surface of the grinding disc 101, or increase the contact of a section, so as to reduce or increase the stroke of the tin wire being ground by the grinding disc 101. Then, the first motor 104 can be started to drive the first transmission belt 105 to drive the first transmission wheel 103 to rotate counterclockwise, so that the first transmission wheel 103 can drive the grinding disc 101 at one end of the rotating column 102 to rotate counterclockwise, and in the process of the rotating column 102 being driven to rotate, the gear 106 fixedly mounted on the outer surface of the rotating column 102 drives another group of gears 106 fixedly mounted on the outer surface of the rotating column 102 to rotate relatively together. Then, the two groups of rotating cylinders 102 can drive the two groups of grinding discs 101 to rotate synchronously relative to each other, so that when the tin wire passes through the two groups of grinding discs 101 in a clockwise manner, the two groups of grinding discs 101 can grind and remove the surface oxide layer of the tin wire passing through the outer surface by relative rotation. This reverse motion increases the relative friction speed between the grinding discs 101 and the tin wire, which can remove the oxide layer more quickly. When the tin wire passes through the outer surface of the grinding disc 101 in the form of u, the upper part of the outer surface of the tin wire will touch the outer surface of the grinding disc 101, and then after passing through the outer surface of the other group of grinding discs 101 in the form of n, the lower part of the outer surface of the tin wire can touch the outer surface of the other group of grinding discs 101.Thus, the outer surface of the tin wire passing through the two sets of grinding discs 101 can be fully polished.

[0057] In summary: the grinding stroke of the tin wire by the grinding disk 101 can be reduced or increased, so that the device can adapt to tin wires with different degrees of oxidation. For tin wires with a lighter degree of oxidation, the grinding stroke can be appropriately shortened to reduce unnecessary grinding and improve production efficiency. For tin wires with severe oxidation, the grinding stroke can be increased to ensure that the oxide layer is completely removed.
