Description

Technical Field

[0001] The present disclosure relates to the technical field of coil production, and in particular to an automated copper coil winding device. Background Art

[0002] Automated copper coil winding equipment is a key piece of equipment in the electronics manufacturing industry, used to efficiently and accurately wind the copper coils used in various electronic components. These components are widely used in transformers, inductors, relays, and other fields, and they place extremely high demands on the product's electrical performance and reliability.

[0003] During the winding process, copper wire may not adhere tightly due to a lack of sufficient adhesion, resulting in unstable winding quality. This can cause problems such as loose coils and irregular arrangement, which in turn affects the electrical performance and reliability of the product. Therefore, methanol needs to be dripped into the copper wire during the winding process to soften the self-adhesive layer of the copper wire and activate its viscosity, so that it has sufficient adhesion and can adhere tightly during the winding process. However, in the existing technology, methanol is usually dripped manually. Manual dripping of methanol requires continuous monitoring and manual operation by operators, which greatly reduces production efficiency. At the same time, manual operation also increases uncertainty and interruption risks in the production process. Moreover, when dripping methanol manually, due to human operational errors and reaction time limitations, it is difficult to ensure that the amount of solution dripped each time is accurate. This can lead to inconsistent adhesion of the copper wire, affecting product quality and performance. Therefore, the development of a winding device with automatic methanol dripping is of great significance for improving production efficiency, ensuring product quality, and realizing intelligent manufacturing.

This significantly reduces manual intervention time and significantly improves production efficiency. Automated operation reduces the risk of production interruptions caused by human factors, such as operator errors and fatigue, ensuring the continuity and stability of the production process.

[0063] like Figure 1 - Figure 4 As shown, the automatic copper coil winding device disclosed in the present disclosure includes a base 10, and a servo tension mechanism 20, a solution transmission component 30, a wire arrangement mechanism 40, a winding rotation mechanism 50, a clamping and cutting wire transfer component 60, a pressing mechanism 70 and a clamping column closing mechanism 80 arranged on the base 10;

[0064] The solution transmission assembly 30 includes a solution storage container 301 for storing the bonding solution, a power member 302, a liquid supply mechanism 303, and a dropper 304. One end of the dropper 304 is connected to the solution storage container 301, and the other end is provided through the power member 302 and connected to the liquid supply mechanism 303. The power member 302 is located vertically above the liquid supply mechanism 303, so that there is a certain height difference between the power member 302 and the liquid supply mechanism 303, and the liquid supply mechanism 303 is located between the servo tension mechanism 20 and the winding rotation mechanism 50. Methanol can be selected as the bonding solution. The power member 302 adopts a peristaltic pump, and the peristaltic pump model MT-410 can be selected. The peristaltic pump is a positive displacement pump that uses a hose to transport fluid. Its working principle is similar to human intestinal peristalsis. It promotes liquid flow by squeezing the hose. It is an efficient, stable, and easy-to-maintain liquid delivery device. The methanol in the solution storage container 301 is transferred to the liquid supply mechanism 303 through the dropper 304 by the power member 302.

[0065] The shearing line transfer assembly 60 includes a shearing line mechanism 601 and a cam transfer mechanism 602. One end of the shearing line mechanism 601 is connected to the cam transfer mechanism 602, and the shearing line transfer assembly 60 is located on the side of the winding rotation mechanism 50 away from the liquid supply mechanism 303; the cam transfer mechanism 602 moves in the horizontal direction and in the vertical direction, that is, the cam transfer mechanism 602 moves toward or away from the winding rotation mechanism 50 in the horizontal direction and moves upward or downward in the vertical direction, and one end of the shearing line mechanism 601 is connected to the cam transfer mechanism 602, so that the movement of the cam transfer mechanism 602 can drive the shearing line mechanism 601 to do the same movement; one end of the shearing line mechanism 601 is fixedly connected to the cam transfer mechanism 602, and can be bolted; the end of the shearing line mechanism 601 away from the cam transfer mechanism 602 is used to clamp the copper wire 90;

[0066] The wire arranging mechanism 40 is arranged below the servo tension mechanism 20. The wire arranging mechanism 40 is used to cooperate with the winding of the winding rotation mechanism 50. The wire arranging mechanism 40 makes a linear motion in the horizontal direction close to or away from the winding rotation mechanism 50. Every time the winding rotation mechanism 50 makes a circle, the wire arranging mechanism 40 moves to the corresponding position. The specific moving distance and direction of the wire arranging mechanism 40 are selected according to actual conditions. The movement of the wire arranging mechanism 40 is driven by a servo motor. For example, the winding rotation mechanism 50 makes 5 circles in one cycle. The first circle is the acceleration stage, the second to fourth circles are the uniform speed stage, and the fifth circle is the deceleration stage. stage, then when winding the first circle, the wire arranging mechanism 40 moves from the initial position to the direction close to the winding rotating mechanism 50, then moves away from the winding rotating mechanism 50, and returns to the initial position, which is a reciprocating motion. When winding the second circle, the wire arranging mechanism 40 moves toward the winding rotating mechanism 50, and when winding the third circle, the wire arranging mechanism 40 moves away from the winding rotating mechanism 50, and returns to the initial position. When winding the fourth circle, the wire arranging mechanism 40 moves toward the winding rotating mechanism 50, and when winding the fifth circle, the wire arranging mechanism 40 moves away from the winding rotating mechanism 50, until the winding rotating mechanism 50 completes 5 circles, and the wire arranging mechanism 40 stops moving;

[0067] One end of the winding rotation mechanism 50 is a clamping end, and a clamping post closing mechanism 80 is provided at the clamping end. The clamping post closing mechanism 80 is used to control the clamping and loosening of the clamping end.

[0068] The pressing mechanism 70 is provided near the wire clamping end, and the pressing mechanism 70 and the wire winding rotating mechanism 50 are located on the same axis; the pressing mechanism 70 is used to press the wire winding rotating mechanism 50 axially;

[0069] One end of the copper wire 90 is sequentially arranged along the servo tension mechanism 20, the solution transmission assembly 30, and the clamping and shearing wire transfer assembly 60, and the clamping and shearing wire mechanism 601 clamps one end of the copper wire 90. The clamping and shearing wire mechanism 601 is moved by the cam transfer mechanism 602 so that the copper wire 90 is placed at the clamping end.

[0070] The solution transmission component 30 can automatically and continuously drip the solution, that is, methanol, without the need for continuous monitoring and manual operation by the operator, which greatly reduces the time of manual intervention and significantly improves production efficiency; automated operation reduces the risk of production interruption caused by human factors, such as operational errors, fatigue, etc., and ensures the continuity and stability of the production process; the precise coordination of the power part 302 and the liquid supply mechanism 303 can accurately control the amount of solution dripped each time, avoiding errors and uncertainties during manual operation, ensuring consistent bonding effect of the copper wire, and improving product quality and performance; and the automated winding device can ensure consistent winding accuracy and bonding effect of the product, thereby improving the overall quality and performance of the product.

[0071] Furthermore, in this embodiment, the liquid supply mechanism 303 includes a liquid impregnated shell 3031 , and the liquid impregnated shell 3031 is a hollow cavity structure;

[0072] The liquid-impregnated housing 3031 has a first extension 3032 and a wire entry hole 3033 on one side thereof, which is close to the servo tension mechanism 20. An anti-jump device 3034 is provided on the end of the first extension 3032 away from the liquid-impregnated housing 3031. The anti-jump device 3034 is a cam-shaped structure and is connected to the first extension 3032 via a bearing.

[0073] The liquid impregnation housing 3031 has a wire outlet on one side close to the winding rotation mechanism 50, and the wire outlet is provided with a wire nozzle 3035;

[0074] The upper surface of the liquid impregnation shell 3031 is provided with a liquid inlet hole 3036, and the dripping tube 304 is connected to the liquid inlet hole 3036, so that the liquid flows from the dripping tube 304 into the interior of the liquid impregnation shell 3031;

[0075] The copper wire 90 is wound around the anti-jump device 3034 , and penetrates into the interior of the liquid-impregnated housing 3031 through the wire inlet hole 3033 and exits through the wire outlet hole through the wire nozzle 3035 .

[0076] Furthermore, in this embodiment, the liquid-impregnated shell 3031 has a second extension portion 3037 at the edge near the liquid inlet hole 3036, and the second extension portion 3037 has a positioning hole adapted to the drip tube 304, and the drip tube 304 is passed through the positioning hole and connected with the liquid inlet hole 3036; since the drip tube 304 needs to pass through the power part 302 and then connect with the liquid supply mechanism 303, and the power part 302 and the liquid supply mechanism 303 have a certain height difference, the drip tube 304 directly connected with the liquid supply mechanism 303 is easy to detach from the liquid inlet hole 3036 or shake, resulting in unstable liquid feeding, so by passing the drip tube 304 through the positioning hole, the drip tube 304 can be stabilized and limited to prevent the drip tube 304 from shaking and detaching from the liquid inlet hole 3036.

[0077] Furthermore, in this embodiment, the surface of the anti-jumping device 3034 that contacts the copper wire 90 is made of ceramic material; the surface made of ceramic material can make the jumping fluctuation during winding very small, further preventing the copper wire from jumping; in order to better prevent the copper wire from jumping, the surface of the anti-jumping device 3034 that contacts the copper wire 90 is mirror polished, and a ceramic rib is also provided to more effectively prevent the copper wire from jumping.

[0078] Furthermore, in this embodiment, the winding rotation mechanism 50 includes a servo motor 501, a coupling 502, a bearing seat 503, a clamping column 504, an upper guide mold 505 and a lower guide mold 506. The output end of the servo motor 501 is rotatably connected to one end of the bearing seat 503 through the coupling 502.

[0079] The wire clamping column 504, the upper guide mold 505 and the lower guide mold 506 are connected to form a wire clamping end, and the wire clamping end is rotatably connected to the end of the bearing seat 503 away from the coupling 502; the pressing mechanism 70 specifically presses the lower guide mold 506 to cooperate with the winding rotation mechanism 50 to complete the winding.

[0080] When the wire clamping post 504 is in the open position, the wire clamping post 504 is in the open position, and the wire clamping post 504 is in the open position, so that the wire clamping post 504 can be clamped.

[0081] In summary, based on the structure of the above-mentioned automated copper coil winding device, the specific winding process is described below:

[0082] One end of the copper wire 90 is sequentially arranged along the servo tension mechanism 20, the solution transmission assembly 30, and the clamping and shearing wire transfer assembly 60, and the clamping and shearing wire mechanism 601 clamps one end of the copper wire 90. The movement of the cam transfer mechanism 602 places the copper wire 90 at the clamping end, that is, the copper wire 90 is placed at the clamping post 504. The clamping post closing mechanism 80 contracts so that the clamping post 504 clamps the copper wire 90. The clamping and shearing wire mechanism 601 returns to its initial position through the movement of the cam transfer mechanism 602. The servo tension mechanism 20 cooperates with the winding rotation mechanism 50 to ensure that the tension of the copper wire 90 is constant.

[0083] The servo motor 501 of the winding rotation mechanism 50 is started, causing the wire clamping end to start rotating. The wire arranging mechanism 40 cooperates with the winding rotation mechanism 50 to perform winding. After winding a specified number of turns of a single product (for example, 5 turns), the pressing mechanism 70 starts pressing, specifically pressing the lower guide mold 506, while the winding rotation mechanism 50 continues to rotate and wind. After the winding is completed, the wire clamping and cutting mechanism 601 moves to the appropriate position through the movement of the cam transfer mechanism 602, and clamps and cuts the wound copper wire 90. The wire clamping column closing mechanism 80 performs an ejection movement to release the wire clamping column 504 from the copper wire 90.

[0084] During the winding process, the power component 302 needs to pump the adhesive solution into the liquid supply mechanism 303 at intervals. The adhesive solution is methanol, so that the copper wire 90 is provided with methanol to activate the self-adhesive layer of the copper wire 90 to soften and activate the viscosity, achieving the effect of bonding while winding. Moreover, due to the interval dripping, the amount of adhesive solution is not excessive, so the primer layer of the copper wire is not damaged.

[0085] As can be seen from the above, the power component 302 adopts a peristaltic pump, so by controlling the roller of the peristaltic pump to roll and rotate along the liquid flow direction of the dropper tube 304 to squeeze the dropper tube 304, the liquid in the dropper tube 304 can flow into the liquid supply mechanism 303 as needed.

[0086] Furthermore, in this embodiment, the automated copper coil winding device further includes a control component 100, and the servo tension mechanism 20, the solution transmission component 30, the wire arrangement mechanism 40, the winding rotation mechanism 50, the clamping and shearing wire transfer component 60, the pressing mechanism 70, and the clamping column closing mechanism 80 are all electrically connected to the control component 100, and the copper wire 90 is wound using the winding processing method through the control component 100;

[0087] The automatic copper coil winding device also includes a warning light 110, which is electrically connected to the control component 100 and is used to respond to alarm information.

[0088] Furthermore, in this embodiment, the winding processing method includes:

[0089] Before winding, set the winding speed V, the number of turns N of a single product and the single dripping amount P of the bonding solution, and calculate and set the dripping time interval △t of the bonding solution;

[0090] Winding is performed according to the dripping time interval △t to form a copper coil, and the first completed copper coil is subjected to an adhesion test. A processing strategy is selected based on the adhesion test result, and the processing strategy includes a parameter unchanged strategy and a dripping increment strategy;

[0091] If the adhesion test passes, the parameter unchanged strategy is executed;

[0092] If the adhesion test fails, an alarm message is issued and the drip increment strategy is executed;

[0093] Parameter-invariant strategies include:

[0094] The remaining copper wire 90 is wound according to the parameters set this time;

[0095] The drip-increment strategy includes:

[0096] The single dripping amount P of the bonding solution is increased by △P, and the winding process is repeated and the adhesion test is performed until the adhesion test passes; that is, the single dripping amount P of the bonding solution is increased by △P each time until the adhesion test passes. After the adhesion test passes, the winding process of the remaining copper wires 90 is performed according to the final value of the last increment; the optimal value of △P is △P=0.1P, so the single dripping amount of the bonding solution after each change is P*(1+0.1P).

[0097] Furthermore, in this embodiment, the calculation of the dripping time interval Δt specifically includes:

[0098] Measure and obtain the actual temperature W in the environment S , actual relative humidity H S , the amount of adhesive solution adsorbed by copper wire 90X S , and the volatilization rate U of the adhesive solution of the copper wire 90 between the liquid supply mechanism 303 and the winding rotation mechanism 50, and the dripping time interval Δt is calculated according to the following formula:

[0099] △t=△t L *(1+C)

[0100] C=K1*[(W S / W L ) / (H S / H L )]+K2*[(V*N) / L]+K3*[X S *(1-U) / P]

[0101] Among them, △t L Indicates the theoretical standard time interval; C is the adjustment coefficient; W L H is the optimal theoretical temperature value for winding processing; L is the optimal theoretical relative humidity value for winding processing; V represents the set winding speed; N represents the set number of turns of a single product; L represents the length of the dropper 304; P represents the set single drop volume of the bonding solution; K1 represents the environmental adjustment coefficient; K2 represents the winding adjustment coefficient; K3 represents the volatilization adjustment coefficient of the bonding solution;

[0102] Since the solution is methanol, and there is a certain distance between the copper wire 90 and the winding rotating mechanism 50 after it passes through the nozzle 3035, a certain amount of methanol will evaporate. Therefore, the calculation of the volatility U is: measure the amount of solution X at the point where the copper wire 90 passes through the nozzle 3035 C1 , for example, X C1 = 0.025 mL, measure the solution volume X of the copper wire 90 before the winding rotating mechanism 50 is wound C2 , for example, X C2=0.020mL, then the volatility U = (0.025-0.020) / 0.025 = 0.2;

[0103] Here is an example:

[0104] Winding speed V = 100r / min, number of turns of a single product N = 5, single drop volume of bonding solution P = 0.05mL, actual temperature W S =25℃, actual relative humidity H S =50%, the amount of adsorption of the adhesive solution X S =0.025mL, volatility U=0.2;

[0105] △t L =5s, W L =20℃, H L =25%, L=50cm, K1=0.4, K2=0.015, K3=0.5;

[0106] C=0.4*[1.25 / 2]+0.015*[500 / 50]+0.5*[0.02 / 0.05]=0.6;

[0107] Then △t=5*(1+0.6)=8s.

[0108] Furthermore, in this embodiment, the adhesion test specifically includes:

[0109] Measure and obtain the maximum tensile force F of the copper ring max , resistance value R S and the actual axial thickness Z S , calculate the adhesion performance coefficient E according to the following formula:

[0110] E=b1*(F max / F L )+b2*(R S / R L )+b3*(Z S / Z L )

[0111] Among them, F L Indicates the theoretical standard tension value; R L Indicates the theoretical optimal resistance value; Z L represents the theoretical axial thickness of the copper ring; b1, b2 and b3 are weight coefficients, and b1+b2+b3=1; the area here represents the cross-sectional area of ​​the copper ring;

[0112] If E≥1, the copper ring is judged to have passed the adhesion test;

[0113] If E<1, the copper ring is judged to have failed the adhesion test;

[0114] Here is an example:

[0115] Maximum tensile force of the copper ring F max =65N, resistance value R S =11Ω, actual axial thickness Z S =3.2cm;

[0116] F L =60N, R L =10Ω, Z L =3cm, b1=0.4, b2=0.2, b3=0.4;

[0117] E=0.4*(65 / 60)+0.2*(11 / 10)+0.4*(3.2 / 3)=1.08>1;

[0118] Therefore, the adhesion test of the copper ring passed.
