Description

Technical Field

[0001] The invention relates to a control method and a system for suppressing wire pile-up phenomenon in a wire drawing welding process, belonging to the technical field of wire drawing welding. Background Art

[0002] In a normal working environment, the wire drawing welding device equipped with a well-designed buffer structure can ensure that the welding wire can pass through the device smoothly and continuously during precision wire drawing welding operations, thanks to its efficient buffer and adjustment mechanism, effectively avoiding wire pile-up caused by speed mismatch or mechanical vibration. This buffer structure not only optimizes the welding process, but also significantly improves welding quality and stability.

[0003] However, when the operation is improper or the equipment is not well maintained, wire pile problems will occur, which seriously threatens the smooth progress of the welding process. For example, if the surface temperature of the welding wire is too high or the cleanliness is insufficient during welding, wire sticking is very likely to occur, causing the welding wire to accumulate in the wire feeding tube, resulting in wire pile; at the same time, if key components in the buffer structure such as the guide wheel or the slider are worn, it may cause the midpoint to drift, resulting in wire pile; in addition, the overall displacement of the buffer structure, whether due to mechanical looseness or external force impact, will directly affect the stability of the wire feeding; what's more, if the sensor is damaged due to aging, short circuit or external interference, it will not be able to accurately monitor and adjust the wire feeding speed, further exacerbating the risk of wire pile.

[0004] Once wire pile occurs, it will not only affect the quality of the welded joint, but may also damage the welding equipment. Currently, the main way to deal with wire pile problems relies on the immediate intervention of on-site operators, who need to manually pull out the bent and piled wires from the narrow wire feeding tube one by one. This process is not only labor-intensive, time-consuming and labor-intensive, increasing unnecessary labor costs, but also directly leads to the stagnation of the production line, seriously reducing production efficiency. Summary of the invention

[0005] The present invention aims to overcome the shortcomings of the prior art and provides a control method and system for suppressing wire accumulation during wire drawing welding. The method and system can obtain a slider position data set where wire accumulation will occur in a buffer structure. By using the slider position data set, when the position of the slider is in the slider position data set and the slider stays at the position for a preset time, the wire feeding speed in the wire drawing welding device is controlled to prevent wire accumulation and improve welding efficiency.

[0006] To achieve the above object, the present invention is implemented by adopting the following technical solutions: On the one hand, the present invention provides a control method for suppressing wire pile phenomenon in a wire drawing welding process, comprising: Periodically calibrating the slider position data of the buffer structure in the wire drawing welding device; Based on the calibrated slider position data and wire accumulation conditions, a slider position data set for generating wire accumulation during wire drawing welding is obtained; When the current position of the slider is in the slider position data set and the time the slider stays at the position is a preset value, the wire feeding speed is controlled to suppress the wire pile phenomenon.

[0007] Optionally, the slider position data of the buffer structure in the wire drawing welding device is periodically calibrated, wherein the calibration process includes: Control the wire feeding speed of the wire drawing motor in the wire drawing welding gun to 0, so that the welding wire is in a stationary state; When the welding wire is stationary, the power-assist mechanism is used to feed the welding wire, and the welding wire is transported from the power-assist mechanism to the wire drawing welding gun, so that the welding wire in the buffer structure is bent, thereby driving the slider to move in the direction of the power-assist mechanism; When the slider stops during the movement toward the power-assisting mechanism and the dwell time reaches a first preset value t1, the position information is obtained through the angle sensor and recorded as the first slider position value Pmax; The wire is withdrawn by the assisting mechanism, and the welding wire is conveyed from the wire drawing welding gun to the assisting mechanism, so that the welding wire in the buffer structure is gradually straightened, thereby driving the slider to move in the direction of the wire drawing welding gun; When the slider stops during its movement toward the wire drawing welding gun and the dwell time reaches a first preset value t1, the position information is obtained through the angle sensor and recorded as the second slider position value Pmin; Based on the first slider position value Pmax and the second slider position value Pmin, the slider midpoint position value p1 is calculated.

[0008] Optionally, the first preset value t1 is 200ms.

[0009] Optionally, based on the calibrated slider position data and wire accumulation conditions, a slider position data set for generating wire accumulation during wire drawing welding is obtained, including: The current position information of the slider during the wire drawing welding process is obtained through the angle sensor, that is, the current slider position value P2; Calculate the percentage P of the current slider position based on the current slider position value P2, the first slider position value Pmax and the slider midpoint position value p1; When the percentage P of the current slider position is ≥95%, and the dwell time of the slider at the current position reaches the wire stacking preset value t, it is determined that the current position of the slider meets the wire stacking condition; When the percentage P of the current slider position is less than 95%, or the dwell time of the slider at the current position does not reach the wire stacking preset value t, it is determined that the current position of the slider does not meet the wire stacking condition; During the wire drawing welding process, all slider positions that meet the wire stacking conditions are recorded to form a slider position data set for generating wire stacking.

[0010] Optionally, the calculation formula for the percentage P of the current slider position is expressed as follows: P = (P2-P1) / (Pmax-P1) Among them, P1 is the midpoint position value of the slider after calibration, and Pmax is the first slider position value.

[0011] Optionally, the wire stacking preset value t=500ms.

[0012] Optionally, when the current position of the slider is in the slider position data set and the time the slider stays at the position is a preset value, the wire feeding speed is controlled to suppress the wire pile phenomenon, including: Obtain the wire feeding speed V and continuous wire feeding time t3 of the power assist motor during the wire drawing welding process; Based on the wire feeding speed V of the assisting motor during wire stacking and the continuous wire feeding time t3, the adjustment speed V1 is calculated; The current position of the slider during wire drawing welding is obtained through the angle sensor; When the current position of the slider is in the slider position data set and the dwell time is the preset value t2, the wire feeding speed of the power assist motor is controlled by adjusting the speed V1: If the adjustment speed V1 ≥ 0, the wire feeding speed of the power assist motor is controlled to be the adjustment speed V1; If the adjustment speed V1<0, the wire feeding speed of the power assist motor is controlled to be 0.

[0013] Optionally, the calculation formula of the adjustment speed V1 is expressed as follows: V1=V *[1- (t3 / t)] Here, * indicates multiplication.

[0014] Optionally, the preset value t2=100ms.

[0015] On the other hand, the present invention provides a control system for suppressing wire pile phenomenon during wire drawing welding, comprising: A calibration module, used for periodically calibrating the slider position data of the buffer structure in the wire drawing welding device; An acquisition module, used for acquiring a slider position data set for generating wire piles during wire drawing welding based on the calibrated slider position data and wire pile conditions; The control module is used to control the wire feeding speed and suppress the wire pile phenomenon when the current position of the slider is in the slider position data set and the time the slider stays at the position is a preset value.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The control method for suppressing wire accumulation during wire drawing welding proposed in the present invention can obtain a slider position data set where wire accumulation will occur in a cache structure, and utilize the slider position data set to prevent wire accumulation from occurring by controlling the wire feeding speed in the wire drawing welding device when the position of the slider is within the slider position data set and the time the slider stays at the position is a preset value, thereby improving welding efficiency.

[0020] In order to facilitate understanding of the control method and system for suppressing wire pile phenomenon in wire drawing welding process provided by the present application, its application scenario is first described. In the prior art, the wire drawing welding device with a buffer structure is composed of an assist mechanism 3-1, a buffer structure 4, and a wire drawing welding gun 3-2; Figure 2 As shown, a power-assisting motor is provided inside the power-assisting mechanism 3-1, and a wire-drawing motor is also provided inside the wire-drawing welding gun 3-2, both of which are used for conveying and withdrawing the welding wire 2; a buffer structure 4 is placed between the power-assisting mechanism 3-1 and the wire-drawing welding gun 3-2, and includes two wire feeding hoses (a first wire feeding hose 6 and a second wire feeding hose 7) which can move relative to each other, and an outer sleeve 5 which is sleeved on the outside of the two wire feeding hoses, one end of the two wire feeding hoses are respectively connected to the wire-drawing welding gun and the power-assisting mechanism, and the other ends (free ends) are sleeved on each other and can slide relatively; a slider 4-1 is provided on the wire feeding hose (the first wire feeding hose 6) connected to the power-assisting mechanism, and when wire drawing welding is performed, the welding wire 2 may pile up when being transported in the two wire feeding hoses, thereby causing the two wire feeding hoses to move relative to each other, and the slider also has a slider fluctuation range.

[0021] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example

[0022] like Figure 1 As shown, an embodiment of the present invention provides a control method for suppressing wire pile phenomenon in wire drawing welding process, comprising the following steps: S01: periodically calibrating the position data of the slider 4-1 of the buffer structure 4 in the wire drawing welding device; S02: based on the calibrated slider position data and wire accumulation conditions, obtaining a slider position data set for generating wire accumulation during wire drawing welding; S03: When the current position of the slider is in the slider position data set and the time the slider stays at the position is a preset value, the wire feeding speed is controlled to suppress the wire pile phenomenon.

[0023] Specifically, the wire drawing welding device mentioned in the present invention can refer to the patent "A structure for welding wire buffering" with announcement number CN 220739907 U.

[0024] The wire drawing welding gun 3-2 and the assisting mechanism 3-1 mentioned above can be respectively represented by the push-draw wire welding gun (the push-draw wire welding gun includes the second wire feeding mechanism) and the first wire feeding mechanism of the patent; the buffer structure 4 can be represented by the components between the first wire feeding mechanism and the second wire feeding mechanism of the patent (two wire feeding hoses, outer sleeve); it should be noted that the first wire feeding mechanism of the patent is a wire pushing device, which is only used for pushing wire, while the assisting mechanism 3-1 of the present invention can be used for pushing and drawing wire (wire feeding and wire withdrawing operations); The components between the first wire feeding mechanism and the second wire feeding mechanism, i.e., the buffer structure 4 of the present invention specifically include: two wire feeding hoses and an outer sleeve 5; the two wire feeding hoses are nested, wherein a part of the structure of one wire feeding hose is placed inside the other wire feeding hose, and the two wire feeding hoses have part of the structure overlapped together, and the two wire feeding hoses can slide relative to each other. Specifically, one end of one of the two wire feeding hoses is connected to the first wire feeding mechanism (wire drawing welding gun 3-2), and one end of the other wire feeding hose is connected to the second wire feeding mechanism (assisting mechanism 3-1), and the welding wire 2 is transported from the first wire feeding mechanism to the second wire feeding mechanism along the inner holes of the two wire feeding hoses. It should be understood that the inner holes of the two wire feeding hoses are divided into three sections, which include the inner hole sections of the two wire feeding hoses and the inner hole sections of the overlapping parts of the two wire feeding hoses; wherein, when the welding wire 2 is transported, it passes through the inner hole section of one wire feeding hose, the inner hole section of the overlapping parts of the two wire feeding hoses, and the inner hole section of the other wire feeding hose in sequence.

[0025] The outer sleeve 5 is sleeved on the outer circumference of the two wire feeding hoses, and the outer sleeve plays a role in protecting and fixing the two wire feeding hoses; the outer sleeve 5 is also connected between the first wire feeding mechanism (the power-assisting mechanism 3-1) and the second wire feeding mechanism (the wire drawing welding gun 3-2), that is, the two ends of the outer sleeve 5 are respectively fixedly connected to the first wire feeding mechanism (the power-assisting mechanism 3-1) and the second wire feeding mechanism (the wire drawing welding gun 3-2). There is also a space reserved between the outer sleeve 5 and the wire feeding hose for the welding wire buffer, which can be realized by providing a sufficiently large inner diameter of the outer sleeve; The control method for suppressing wire accumulation during wire drawing welding proposed in the present invention can obtain a slider position data set where wire accumulation will occur in a cache structure. When the position of the slider is within the slider position data set and the time the slider stays at the position is a preset value, the wire feeding speed in the wire drawing welding device is controlled to prevent wire accumulation and improve welding efficiency.

[0026] In this embodiment, in step S01, when the slider position data of the buffer structure 4 in the wire drawing welding device is periodically calibrated, every three days is a cycle, and the calibration method specifically includes the following: Control the wire feeding speed of the wire drawing motor in the wire drawing welding gun 3-2 to be 0, so that the welding wire 2 is in a stationary state; When the welding wire 2 is stationary, the power-assist mechanism 3-1 is used to perform wire feeding operation, and the welding wire 2 is conveyed from the power-assist mechanism 3-1 to the wire drawing welding gun 3-2, so that the welding wire 2 in the buffer structure 4 is bent, thereby driving the slider 4-1 to move in the direction of the power-assist mechanism 3-1; When the slider 4 - 1 stops during its movement toward the power-assisting mechanism 3 - 1 and the dwell time reaches a first preset value t1, the position information is acquired through the angle sensor and recorded as the first slider position value Pmax; The wire retracting operation is performed through the assisting mechanism 3-1, and the welding wire 2 is conveyed from the wire drawing welding gun 3-2 to the assisting mechanism 3-1, so that the welding wire 2 in the buffer structure 4 is gradually straightened, thereby driving the slider 4-1 to move in the direction of the wire drawing welding gun 3-2; When the slider 4-1 stops during its movement toward the wire drawing welding gun 3-2 and the dwell time reaches the first preset value t1, the position information is obtained through the angle sensor and recorded as the second slider position value Pmin; Based on the first slider position value Pmax and the second slider position value Pmin, the slider midpoint position value p1 is calculated, as shown below: p1 = (Pmax + Pmin) / 2 Specifically, when the wire drawing motor is not operating, the power-assisting motor inside the power-assisting mechanism 3-1 is used to perform wire feeding operation, and the welding wire 2 is delivered to the wire drawing welding gun 3-2 through the buffer structure 4 (two wire feeding hoses); at this time, since the wire drawing motor inside the wire drawing welding gun 3-2 does not perform wire feeding movement, the welding wire 2 is piled up in the buffer structure 4, so that the relative distance between the two wire feeding hoses becomes longer, and the slider 4-1 (limiting block) connected to the wire feeding hose moves toward the power-assisting mechanism 3-1 until it reaches the maximum range and stops, and stops exceeding the first preset value t1, and the position value, i.e., the first slider position value Pmax, is recorded; The power-assisting motor inside the power-assisting mechanism 3-1 is used to perform the wire retracting operation, and the welding wire 2 is retracted from the wire-drawing welding gun 3-2 to the power-assisting mechanism 3-1 through the buffer structure 4 (two wire feeding hoses); at this time, the welding wire 2 stacked in the buffer structure 4 is gradually straightened, so that the relative distance between the two wire feeding hoses becomes shorter, and the slider 4-1 (limit block) connected to the wire feeding hose moves toward the direction of the wire-drawing welding gun 3-2 until it reaches the minimum range and stops, and stops exceeding the first preset value t1, and the position value, i.e., the second slider position value Pmin, is recorded.

[0027] Specifically, in this embodiment, the first preset value t1 is 200 ms.

[0028] In this embodiment, in step S02, based on the calibrated slider position data and wire accumulation conditions, a slider position data set for generating wire accumulation during wire drawing welding is obtained, which specifically includes: The information of the current position of the slider is obtained through the angle sensor, that is, the current slider position value P2; Based on the current slider position value P2, the first slider position value Pmax and the slider midpoint position value p1, the percentage P of the current slider position is calculated; the calculation formula of the percentage P of the previous slider position is expressed as follows: P = (P2-P1) / (Pmax-P1) When the percentage P of the current slider position is ≥95%, and the dwell time of the slider at the current position reaches the wire stacking preset value t, it is determined that the current position of the slider meets the wire stacking condition; When the percentage P of the current slider position is less than 95%, or the dwell time of the slider at the current position does not reach the wire stacking preset value t, it is determined that the current position of the slider does not meet the wire stacking condition; During the wire drawing welding process, all slider positions that meet the wire stacking conditions are recorded to form a slider position data set for generating wire stacking.

[0029] Specifically, the preset value t of the wire stacking time is 500 ms.

[0030] In this embodiment, in step S03, when the current position of the slider is in the slider position data set and the time the slider stays at the position is a preset value, the wire feeding speed is controlled to suppress the wire pile phenomenon, specifically including: Obtain the wire feeding speed V and continuous wire feeding time t3 of the power assist motor during the wire drawing welding process; Based on the wire feeding speed V of the assist motor during wire stacking and the continuous wire feeding time t3, the adjustment speed V1 is calculated using the following formula: V1=V *[1- (t3 / t)] The current position of the slider during wire drawing welding is obtained through the angle sensor; When the current position of the slider is in the slider position data set and the dwell time is the preset value t2, the wire feeding speed of the power assist motor is controlled by adjusting the speed V1: If the adjustment speed V1 ≥ 0, the wire feeding speed of the power assist motor is controlled to be the adjustment speed V1; If the adjustment speed V1<0, the wire feeding speed of the power assist motor is controlled to be 0.

The above-mentioned specific implementation methods are merely illustrative and not restrictive.
