Description

Technical Field

[0001] The present invention relates to the technical field of copper wire measurement, and particularly to a diameter measurement mechanism for copper wire production and its working method. Background Art

[0002] During the production process of copper wire, it is necessary to measure the diameter of the copper wire in real time. When there is a problem with the diameter of the copper wire, it is necessary to detect and alarm in time to ensure the product quality of the copper wire. In the existing related technologies, since the copper wire is continuously discharged during processing, usually only two rollers are used to clamp the copper wire, and the diameter of the copper wire is measured by measuring the distance between the rollers. However, since the diameter of the copper wire itself is only a few millimeters, its diameter change is very small. Not only does the existing measurement device need to be sensitive enough, but the existing measurement method has a low measurement accuracy for such small changes and it is difficult to accurately measure the change of the copper wire diameter. Summary of the Invention

[0003] The present invention provides a diameter measurement mechanism for copper wire production and its working method, which can effectively solve the problem that the existing measurement means has a low measurement accuracy for the change of the copper wire diameter in the background art.

[0005] A frame for carrying components;

[0006] A plurality of measurement components arranged on the frame;

[0007] A measurement wire, one end of which is fixed to the frame and the other end is connected to a displacement sensor fixed on the frame;

[0008] Each measurement component includes:

[0009] A fixed roller that rotates along its own axis and is relatively fixed to the frame;

[0010] A sliding roller that rotates along its own axis and makes a linear motion of approaching and departing from the fixed roller;

[0011] A thrust mechanism for pushing the sliding roller towards the fixed roller;

[0012] The copper wire passes through between the fixed roller and the sliding roller;

[0013] Two winding wheels are respectively arranged coaxially with the fixed roller and the sliding roller;

[0014] In two adjacent measurement components, the positions of the fixed roller and the sliding roller on both sides of the copper wire are opposite;

[0015] The measuring wire passes through the wire winding wheels corresponding to the sliding rollers of each measuring component in sequence, and also passes through the wire winding wheels corresponding to the fixed rollers of the measuring components at both ends.

[0016] Furthermore, it also includes a limit block fixed on the frame; a limit hole penetrating along the moving direction of the copper wire is provided on the limit block, and the limit hole is aligned between the fixed roller and the sliding roller.

[0017] Furthermore, in each measuring component, limit plates extending radially outward are provided at both ends of the fixed roller; relief grooves are circumferentially provided at both ends of the sliding roller; the limit plates always extend into the relief grooves.

[0018] Furthermore, the sides of the fixed roller and the sliding roller are both in the shape of a cylinder.

[0019] Furthermore, it also includes a power mechanism for driving all the fixed rollers to rotate.

[0020] Furthermore, two belt pulleys are arranged in each measuring component, both belt pulleys rotate synchronously with the fixed roller, and one belt pulley in each adjacent measuring component is in transmission connection.

[0021] Furthermore, in each measuring component, it also includes a slider sliding on the frame; the sliding roller rotates on the slider;

[0022] The power mechanism includes a rotating rod rotating on the frame, an adjusting block sliding in the slider, and a spring arranged between the adjusting block and the slider; one end of the rotating rod is screwed into the adjusting block.

[0023] The present invention also provides a working method for the diameter measuring mechanism for copper wire production, which is used for the above-mentioned diameter measuring mechanism for copper wire production, and includes:

[0024] S10: Fit the fixed roller and the sliding roller of each measuring component, install the measuring wire, and record the reading of the displacement sensor at this time as L0;

[0025] S20: Pass the copper wire through all the measuring components;

[0026] S30: Read the reading L of the displacement sensor in real time, calculate ΔL = L - L0, and calculate the copper wire diameter D based on this;

[0027] S40: Output the value of the copper wire diameter D outward.

[0028] Furthermore, in step S30, the specific calculation of the copper wire diameter D is:

[0029] Establish:

[0030] ;

[0031] Among them, n is the number of measurement components; a is the distance between the centers of two fixed rollers in adjacent measurement components in the movement direction of the copper wire; b is the center distance between the fixed roller and the sliding roller in the measurement component when they are in close contact; d is the diameter of the wire winding wheel;

[0032] After solving, the positive value of D obtained is the diameter D of the copper wire.

[0033] Furthermore, in step S20, before installing the copper wire, first use a metal wire with a diameter of D0 to pass through all the measurement components, and then use steps S40 - 50 to calculate the diameter D of the copper wire once. If the difference between D and D0 is within the set range, then replace the copper wire and proceed with the subsequent measurement.

[0034] Through the technical solution of the present invention, the following technical effects can be achieved:

Thus, the present detection mechanism can accurately measure the subtle diameter change of the copper wire. At the same time, the present measurement mechanism can maintain the continuous production of the copper wire during measurement and can measure all positions of the whole copper wire, thereby effectively ensuring the production efficiency and production quality of the copper wire.

Detailed implementation manners

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0046] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0047] The present invention relates to a diameter measuring mechanism for copper wire production, as Figures 1 - 4 shown, including:

[0048] A frame, fixedly installed on the ground or the fixing frame of other equipment, for carrying other components of this mechanism;

[0049] A plurality of measuring components, all arranged on the frame, and the plurality of measuring components are distributed along the advancing direction of the copper wire;

[0050] The measuring wire 2, one end is fixed to the frame, and the other end is connected to a displacement sensor fixed on the frame. The displacement sensor is mainly used to measure the change amount of the position of this section of the measuring wire 2; The measuring wire 2 can be made of a material with a smooth surface and wear resistance such as a nylon rope;

[0051] The number of measuring components can be adjusted according to the measurement requirements. The more components there are, the higher the measurement accuracy of the copper wire diameter will be.

[0052] The structures of all measuring components are the same. Each measuring component includes:

[0053] A fixed roller 3 that rotates along its own axis and is relatively fixed to the frame;

[0054] A sliding roller 4 that rotates along its own axis and moves linearly towards and away from the fixed roller 3;

[0055] The copper wire passes through between the fixed roller 3 and the sliding roller 4;

[0056] A thrust mechanism that always applies a thrust to the rotating shaft of the sliding roller 4 to push the sliding roller 4 towards the fixed roller 3, so that the sliding roller 4 and the fixed roller 3 can always be in contact with the copper wire;

[0057] Two winding wheels 5 are respectively arranged coaxially with the fixed roller 3 and the sliding roller 4. The winding wheel 5 corresponding to the fixed roller 3 will always remain relatively fixed to the frame, while the winding wheel 5 corresponding to the sliding roller 4 will move along with the linear movement of the sliding roller 4;

[0058] In two adjacent measuring components, the positions of the fixed roller 3 and the sliding roller 4 on both sides of the copper wire are opposite, that is: if the forward direction of the copper wire is defined as the front, in one measuring component, the fixed roller 3 is on the left side of the copper wire and the sliding roller 4 is on the right side of the copper wire, then in the adjacent measuring component, the fixed roller 3 is on the right side of the copper wire and the sliding roller 4 is on the left side of the copper wire;

[0059] The measuring wire 2 passes through the winding wheels 5 corresponding to the sliding rollers 4 of each measuring component in turn, and also passes through the winding wheels 5 corresponding to the fixed rollers 3 of the measuring components at both ends, forming a Figure 5 snake-like shape as shown.

[0060] The specific working principle of this measuring mechanism is as follows:

[0061] When the copper wire is produced, the produced copper wire will be put into this measuring mechanism for size detection. Under the action of the thrust mechanism, the fixed roller 3 and the sliding roller 4 will always clamp the copper wire. Therefore, when the diameter of the copper wire changes, the sliding rollers 4 of each measuring mechanism will move accordingly, that is, when the diameter of the copper wire increases, the sliding roller 4 will move away from the fixed roller 3, and when the diameter of the copper wire decreases, the sliding roller 4 will move closer to the fixed roller 3; and the winding wheel 5 moves synchronously with the sliding roller 4, and the movement of the winding wheel 5 will drive the measuring wire 2, so that the position of the end of the measuring wire 2 connected to the displacement sensor changes. There is a clear corresponding relationship between the change amount of this position and the change of the copper wire diameter. Therefore, the change amount of the copper wire diameter can be calculated from this.

[0062] Different from traditional measuring mechanisms, for the measuring mechanism of the present invention, the moving distances of the sliding rollers 4 in all measuring components are accumulated onto the displacement at the end of the measuring wire 2, that is, the change in the diameter of the copper wire is amplified. Moreover, the more the number of measuring components, the greater this amplified amount, so that the present detection mechanism can accurately measure the subtle diameter changes of the copper wire. At the same time, the present measuring mechanism can maintain the continuous production of the copper wire during measurement and can measure all positions of the entire copper wire, thus effectively ensuring the production efficiency and production quality of the copper wire.

[0063] Generally, there will be rotating shafts at the centers of the fixed rollers 3 and the sliding rollers 4, and the wire winding wheels 5 will be installed on these rotating shafts. During installation, it is necessary to make the wire winding wheels 5 rotatable freely on the rotating shafts so that they can rotate independently with respect to the fixed rollers 3 or the sliding rollers 4, thereby preventing the fixed rollers 3 or the sliding rollers 4 from driving the wire winding wheels 5 to rotate when rotating and ensuring that the measuring wire 2 is not interfered with.

[0064] In the measuring mechanism of the present invention, the frame includes a plurality of mounting seats 11 for mounting each measuring component. The outer shape of the mounting seat 11 is a centrosymmetric shape, so that the structural shapes of the mounting seats 11 used for each measuring component are the same. During the assembly process, only by rotating the mounting seat 11 at the corresponding position by 180°, the requirements that the positions of the fixed rollers 3 and the sliding rollers 4 of adjacent measuring components are opposite can be achieved, thereby reducing the production and assembly costs. A plurality of clamping blocks 12 with only half the thickness of the mounting seat 11 can also be provided on the side of the mounting seat 11. When two adjacent mounting seats 11 are combined, the clamping blocks 12 of the two mounting seats 11 will fit together, so that the corresponding relationship between the positions of the mounting seats 11 is more accurate.

[0065] In the mounting seat 11 corresponding to each measuring component, a sliding groove for the slider 7 to slide is provided. The sliding roller 4 rotates on the slider 7, and the side walls of the sliding groove fit against both sides of the slider 7, thereby precisely restricting the movement track of the slider 7. When needed, limit blocks 6 can also be fixedly installed on one side or both sides of each mounting seat 11; a limiting hole 61 penetrating along the moving direction of the copper wire is provided on the limit block 6, and the limiting hole 61 is aligned between the fixed roller 3 and the sliding roller 4. During measurement, the copper wire passes through the limiting hole 61, and the position of the copper wire is restricted to a certain extent through the limiting hole 61, so that the copper wire will not have excessive skew deviation. The limiting hole 61 preferably adopts a waist-shaped hole structure, and the length direction of the waist-shaped hole is parallel to the connection line of the fixed roller 3 and the sliding roller 4, leaving a certain space for the possible movement of the copper wire.

[0066] In addition to limiting the copper wire by the limiting block 6, in each measuring component, limiting plates 31 extending radially outward are provided at both ends of the fixed roller 3; relief grooves 41 are circumferentially provided at both ends of the sliding roller 4; the length of the limiting plate 31 extending outward is controlled so that when the sliding roller 4 moves to any position it can reach, the limiting plate 31 can always extend into the relief groove 41, thereby forming an annular cavity for the copper wire to pass through between the fixed roller 3 and the sliding roller 4, thus preventing the copper wire from deviating out of the space between the fixed roller 3 and the sliding roller 4. Once such a limiting structure is available, the sides of the fixed roller 3 and the sliding roller 4 can both be set in a cylindrical shape, so that the distance between the fixed roller 3 and the sliding roller 4 can be guaranteed to be equal to the diameter of the copper wire regardless of the position of the copper wire.

[0067] The fixed roller 3 and the sliding roller 4 can be set in the same shape, and both are respectively installed on the mounting seat 11 and the slider 7 through the bushing 9, so that it is not necessary to specifically distinguish between the fixed roller 3 and the sliding roller 4 during the manufacturing process, thereby saving the manufacturing cost. The limiting plate 31 can be an independent component. After determining the fixed roller 3, the limiting plate 31 is installed on the fixed roller 3 to fill its relief groove.

[0068] Both ends of the measuring wire 2 are preferably detachably connected between the frame and the displacement sensor. In this way, when the measuring wire 2 is wound around the measuring component, the measuring wire 2 can be detached separately first for convenient operation, and then connected to the frame and the displacement sensor after the measuring wire 2 is wound. Threaded sleeves, hooks and other structures can be provided at both ends of the measuring wire 2 to achieve its detachable function.

[0069] If the copper wire is used to drive the rotation of the fixed roller 3 and the sliding roller 4, the friction between the copper wire and the two rollers will be very large, which is likely to damage the outer surface of the copper wire. To avoid this problem, a power mechanism for driving the rotation of all the fixed rollers 3 is also provided in this measuring mechanism, so that the fixed roller 3 can change from passive rotation to active rotation, thereby effectively protecting the outer surface of the copper wire.

[0070] Since the fixed roller 3 has no requirement for driving the copper wire, but the synchronism of the rotation of the fixed rollers 3 between each measuring component is required to be relatively high. Therefore, in this measuring mechanism, two belt pulleys 32 are provided in each measuring component, and both belt pulleys 32 rotate synchronously with the fixed roller 3, and one belt pulley 32 in each adjacent measuring component is connected by a belt drive, so that all the fixed rollers 3 can be connected together for synchronous rotation, and when the number of measuring components is changed, this structure can also conveniently realize the connection of the fixed rollers 3 between any number of measuring components. The belt pulley 32 and the winding wheel 5 are preferably arranged on both sides of the mounting seat 11 respectively to avoid interference between the belt and the measuring wire 2.

[0071] The thrust mechanism can be simply implemented by setting an elastic structure between the frame and the slider 7. However, for copper wires with different diameters, if the elastic force of the elastic structure cannot change correspondingly, then when measuring large-diameter copper wires, excessive pressure will be exerted on the copper wire, resulting in damage to the copper wire. To solve the above problems, as Figure 3 shown, this measuring mechanism is provided with a rotatable screw rod 81 on the frame, an adjusting block 82 that slides within the slider 7, and a spring 83 provided between the adjusting block 82 and the slider 7; one end of the screw rod 81 is threadedly screwed into the adjusting block 82. By rotating the screw rod 81, the position of the adjusting block 82 can be adjusted, thereby controlling the compression degree of the spring 83 and realizing the adjustment of the thrust magnitude of the thrust mechanism.

[0072] The present invention also relates to a working method of a diameter measuring mechanism for copper wire production, which is used for the above-mentioned diameter measuring mechanism for copper wire production, and includes:

[0073] S10: Fit the fixed roller 3 and the sliding roller 4 of each measuring component. When necessary, the screw rod 81 can be rotated to adjust the thrust magnitude of the thrust mechanism on the sliding roller 4; then install the measuring wire 2. At this time, it is the limit position of this mechanism (which can be regarded as the position where the diameter of the copper wire is 0). It is necessary to ensure that the displacement sensor is slightly extended and can generate a reading at this moment, so that this measuring mechanism can accurately reflect this limit position, and record the reading of the displacement sensor at this time as L0;

[0074] S20: Pass the copper wire through all the measuring components;

[0075] S30: Read the reading L of the displacement sensor in real time, calculate △L = L - L0, and calculate the copper wire diameter D based on this;

[0076] S40: Output the value of the copper wire diameter D outward. When outputting, the copper wire diameter D can be judged to determine whether the copper wire diameter D is within the range of the qualified copper wire diameter set in this production. If not, an alarm is issued.

[0077] In step S30, the specific calculation of the copper wire diameter D is as follows:

[0078] Establish:

[0079] ;

[0080] where n is the number of measuring components; a is the distance between the centers of two fixed rollers 3 in the copper wire movement direction in adjacent measuring components; b is the center distance between the fixed roller 3 and the sliding roller 4 in the measuring component when they are in close contact; d is the diameter of the wire winding wheel 5;

[0081] After solving, the positive value of D is the copper wire diameter D.

[0082] The specific principle of this calculation formula is as follows:

[0083] In two adjacent measuring components, since the diameter of the winding wheel 5 is relatively small, the portion of the measuring line 2 wrapped around the winding wheel 5 can be approximately regarded as a straight line. In this case, the measuring line 2 between the two winding wheels 5 can be regarded as the hypotenuse of a complete right triangle.

[0084] When in the extreme position (i.e. when the fixed roller 3 and the sliding roller 4 are in close contact), Figure 5 As shown, the lengths of the two right-angled sides of the right triangle are a and b+2·d / 2=b+d. At this time, the reading of the displacement sensor is L0.

[0085] Now the total distance H0 that the measuring line 2 wraps around the measuring component is (n-1) the hypotenuse of the right triangle. Add two vertical sides b+d, that is ;

[0086] After the copper wire passes between the fixed roller 3 and the sliding roller 4, as the sliding roller 4 moves, Figure 6 As shown, one endpoint of the hypotenuse of the right triangle moves upward by D, and the other endpoint of the hypotenuse moves downward by D, and the width remains unchanged. Then the lengths of the two right-angled sides of the new right triangle are a and b+d+2D respectively.

[0087] Now the length of the hypotenuse of each right triangle is ;

[0088] Now the total distance H that the measuring line 2 wraps around the measuring component is (n-1) the hypotenuse of the right triangle. Add two vertical sides b+d+D, that is ;

[0089] At this time, the connection point between the measuring line 2 and the frame remains unchanged, while the connection point between the displacement sensors of the measuring line 2 moves by △L=L-L0. The extra △L is the extra distance of the measuring line 2 on the measuring component, that is, △L=H-H0.

[0090] Combining the above formulas, we can obtain:

[0091] ;

[0092] In the above formula, except for D, all other data are known values, so the size of the copper wire diameter D can be solved based on this.

[0093] To determine whether there are problems with this measuring mechanism itself, it is preferable to first conduct a trial measurement in step S20 to test the accuracy of this measuring mechanism, that is: before installing the copper wire, first pass a metal wire with a diameter of D0 through all the measuring components. This metal wire needs to be re-measured before each installation to obtain an accurate D0, and the material hardness of the metal wire is preferably higher than that of the copper wire to prevent deformation of the metal wire during the trial measurement from affecting the trial measurement results; then use steps S40 - 50 to calculate the diameter D of the copper wire once. If the difference between D and D0 is within the set range, it indicates that the state of this measuring mechanism is good, and then the copper wire can be replaced for subsequent formal measurement.

[0094] The above has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
