Description
Technical Field
The invention relates to the field of ultrasonic application, in particular to an intelligent planning method, device and system for an ultrasonic sewing business process.
Background
Ultrasonic sewing is a technique for realizing the processes of fusing, sewing, cutting and the like of materials by utilizing ultrasonic waves generated by high-frequency mechanical vibration. The essence is the application of ultrasonic welding in the field of clothing. Ultrasonic sewing is also widely used in garment manufacturing, particularly in some special materials, detail handling and rapid production.
The ultrasonic sewing can realize needleless sewing, and the two layers of fabrics are fused together at the molecular level under the action of ultrasonic waves, so that the traditional sewing thread is replaced. In addition, the ultrasonic sewing can be used for cutting fabrics and closing edges at the same time, so that loose fibers of the fabrics are prevented, and burrs are effectively avoided. For some parts needing fine treatment, such as pockets, necklines, cuffs and the like, the ultrasonic sewing can realize accurate sewing and fusing, and various complex patterns can be accurately cut without additional dies or cutters, so that the process quality is ensured. In some cases where multiple textile materials are desired to be combined into a composite material, ultrasonic sewing may be effective to join them together to meet specific performance requirements.
In achieving ultrasonic sewing of clothing, there are many factors that affect the sewing effect, such as material type and properties, pressure, frequency and power, welding time, and ambient temperature waiting. Different materials respond differently to ultrasound waves, some materials may be more easily melted and connected, while other materials may require higher power and time. The thickness, density, elasticity, etc. of the material also affect the sewing effect. Proper pressure can ensure that materials are in close contact under the action of ultrasonic waves, so that better connection is realized; too low a pressure may result in the materials not fusing together, while too high a pressure may damage the materials. The ambient temperature may affect the properties of the material and the sewing effect, and the melting point and elasticity of the material at different temperatures may be different.
When the cloth is sewn by ultrasonic waves, the temperature needs to be effectively controlled so as to realize the optimal sewing effect and connection quality. The temperature is related to the melting point of the cloth, and different sewing temperatures are required for different types of cloth. When the clothing is formed by combining multiple materials, different sewing positions need different sewing temperatures, and the existing scheme generally sets waiting time for cooling so as to meet the sewing requirements of different sewing temperatures. The waiting time can greatly increase the cost of ultrasonic sewing and reduce the sewing efficiency.

Example 1
The embodiment provides an intelligent planning method for an ultrasonic sewing business process, sewing is carried out according to the sequence from low sewing temperature to high sewing temperature to low sewing temperature, the temperature characteristic of an ultrasonic assembly is fully utilized, and the sewing quality is improved. The flow diagram of the intelligent planning method of the ultrasonic sewing business flow is shown in the attached figure 1 of the specification, and the specific scheme is as follows:
an intelligent planning method for an ultrasonic sewing business process comprises the following steps:
101. classifying the cloth sewn by the ultrasonic sewing device according to the melting point and melting characteristic in advance to obtain three cloth types of high-melting-point cloth, medium-melting-point cloth and low-melting-point cloth;
102. acquiring a cloth to be sewn, which at least comprises two types of cloth in the high-melting-point cloth, the middle-melting-point cloth and the low-melting-point cloth, and setting the area of a sewing platform based on the whole area of the cloth to be sewn;
103. analyzing each sewing position on the cloth to be sewn, and setting the optimal sewing temperature and sewing speed of each sewing position based on the characteristics of each sewing position including the thickness and the cloth type;
104. based on the optimal sewing temperature and the position of each sewing position, combining the sewing sequence of each sewing position, so that the optimal sewing temperature of each sewing position in the sewing sequence shows a trend from low to high to low;
105. the sewing is carried out on the sewing platform according to the sewing sequence and the corresponding sewing speed, and the heating condition of the ultrasonic sewing device is fed back by detecting the real-time temperature of the welding head and the ultrasonic transducer, so that the parameters of the cooling mechanism at least positioned at the welding head and the ultrasonic transducer are regulated in real time.
The intelligent planning method of the ultrasonic sewing business process fully considers the individuation difference of the ultrasonic sewing device and performs customized design on the type of the cloth. The power of the ultrasonic sewing device is different, and the sewing temperature interval can be different, so that the types of the clothes are classified in the sewing temperature interval. The melting point and melting characteristics of the cloth reflect to some extent its sewing temperature, and in general, the temperature generated by ultrasonic sewing is typically near the melting point of the material, but does not necessarily reach the full melting temperature of the material. The embodiment divides the types of the high-melting-point cloth, the medium-melting-point cloth and the low-melting-point cloth so as to conveniently select proper sewing temperature. In practical application, if the sewing temperature interval of the ultrasonic sewing device is large, more cloth types can be set.
Illustratively, low melting point garments include cotton, hemp, silk, and the like, with sewing temperatures of about 100 ℃ to 150 ℃, such garments having lower melting points and lower sewing temperatures. The medium-melting-point cloth comprises wool, nylon, polyethylene, polypropylene and the like, and the sewing temperature is about 150 ℃ to 220 ℃. And the high-melting-point clothing mainly comprises thermosetting plastics, composite materials and special coating materials, and the sewing temperature is about 220 ℃ to 300 ℃. The sewing temperature range of the composite material may vary depending on the combination of different fibers. The particular coating material, such as a water-repellent, wind-repellent coating, etc., will vary in temperature range depending on the type of coating. Many other types of materials are also contemplated in practice, each having different characteristics and uses. Before sewing the cloth, the cloth needs to be classified into proper types according to the characteristics of the cloth, and proper optimal sewing temperature is selected.
The cloth to be sewn has specificity, and only aims at cloth types at least comprising two types of cloth in high-melting-point cloth, medium-melting-point cloth and low-melting-point cloth. When the cloth has various melting points at the positions to be sewn, the sewing sequence needs to be reasonably adjusted. If the cloth to be sewn is made of one material, the sewing sequence does not need to be excessively adjusted. In addition, the cloth to be sewn in the embodiment may have a special shape, unlike the conventional garment, which is relatively fixed in size, so that the size of the sewing platform needs to be adjusted. By way of example, a foldable plate body can be arranged on the sewing platform, the plate body can be unfolded when needed, and the plate body can be folded when not needed, so that the expandability of the sewing platform can be realized.
In this embodiment, each portion to be sewn on the cloth to be sewn is referred to as a sewing portion, and characteristics including length, thickness, material and position of each sewing portion on the cloth to be sewn are analyzed. The length determines the sewing time at the position, the thickness and the material determine the sewing temperature and the sewing speed at the position, and the position determines the sewing sequence at the position. The optimal sewing temperature and sewing speed of each sewing position are set based on the characteristics of each sewing position including the thickness and the cloth type, the cloth type of each sewing position is only needed to be judged, the sewing temperature interval corresponding to the cloth type is selected, and the relevant optimal sewing temperature can be selected by combining the thickness. The optimal sewing temperature can be a specific temperature or a temperature range.
Preferably, the intelligent planning method of the ultrasonic sewing business process of the embodiment constructs a comparison relation table of sewing temperatures in advance, and the optimal sewing temperature can be obtained only by looking up the related data in the table. Specifically, respectively constructing the comparison relation between the sewing speed interval and the sewing temperature interval of the high-melting-point cloth, the middle-melting-point cloth and the low-melting-point cloth under one or more preset standard thicknesses; calculating the sewing speed of the sewing position in a corresponding sewing speed interval by analyzing the difference value between the thickness of the sewing position and each standard thickness; judging the type of the cloth to which the sewing position belongs, and selecting one from sewing temperature intervals corresponding to the type of the cloth as the optimal sewing temperature. Generally, the thickness of the sewing part and the sewing speed are approximately in linear relation, a standard sewing thickness is set, and the sewing speed of the sewing part is obtained according to the linear relation. In addition, the thickness also affects the sewing temperature to a certain extent, and when the thickness exceeds the standard thickness, a higher temperature can be selected in the temperature interval as the optimal sewing temperature.
After the optimal sewing temperature of each sewing position is obtained, the sewing sequence can be constructed. Based on the optimal sewing temperature and the position of each sewing position, the sewing sequence of each sewing position is combined, so that the optimal sewing temperature of each sewing position in the sewing sequence shows a trend from low to high to low. The sewing sequence is carried out according to the sequence of low, high and low, so that the ultrasonic sewing device can gradually sew, the temperature of the welding head is fully utilized to quicken the sewing of the clothing, and meanwhile, the sewing device cannot be in a high-temperature state for a long time, and the negative influence caused by the temperature is reduced.
The temperature generated by the ultrasonic vibration may locally melt the surface of the material. This helps to bond the two pieces together, forming a strong joint. Too low a temperature may result in insufficient melting and weak connection; excessive temperatures may result in excessive melting and damage to the material. The proper temperature can increase the efficiency of the sewing because the material can be melted and joined more easily over a range of temperatures. However, excessive temperatures may result in wasted energy and may require additional cooling steps. The temperature of the welding head can be utilized to accelerate the temperature of the cloth to rise to the sewing temperature. Preferably, the acquiring process of the sewing sequence specifically includes: sequencing all sewing positions in sequence according to the optimal sewing temperature, and determining the positions of one or more sewing positions in the sewing sequence when the optimal sewing temperature is highest to obtain an initial sequence group; and sequentially determining the sewing positions around the initial sequence group by taking the sewing positions in the initial sequence group as starting points according to the principle of taking the optimal sewing temperature as the main and the position as the auxiliary until the sewing sequence is established. Further preferably, when the highest optimal sewing temperature corresponds to a plurality of sewing positions at the same time, all possible arrangement sequences are planned; sequentially analyzing the moving distance and the moving mode of a preset moving mechanism required by each arrangement sequence, selecting one or more arrangement sequences with the shortest moving distance and the simplest moving mode from the moving distances, and combining the starting point and the end point of the arrangement sequences to obtain a final starting sequence group if other sewing positions with optimal sewing temperature exist around the sewing position.
The sewing sequence is low-high-low, the highest temperature can be determined first, and then other temperatures can be determined sequentially from the highest temperature to both sides. The sewing parts with relatively close positions can be bound in sequence, and other temperatures can be determined in sequence from the lowest temperature and the highest temperature of the sewing parts to the two sides. There are many ways to determine the sewing sequence, and only one or more temperatures need to be determined preferentially, and other temperatures can be determined by taking the temperature of the part as a starting point.
When the sewing sequence is concerned, not only the temperature but also the position of the sewing position are considered. In practical applications, the switching between sewing positions is usually achieved by moving the cloth by means of a moving mechanism on the ultrasonic sewing device. In the case of movement, it is also necessary to reduce the power consumption of the moving mechanism as much as possible in consideration of the moving mode and the moving path of the moving mechanism. At the same time, complex shapes may require specific angles and methods to achieve an effective connection, and the movement mechanism may also take into account relevant factors when moving.
The sewing is carried out on the sewing platform according to the sewing sequence and the corresponding sewing speed, and the heating condition of the ultrasonic sewing device is fed back by detecting the real-time temperature of the welding head and the ultrasonic transducer, so that the parameters of the cooling mechanism at least positioned at the welding head and the ultrasonic transducer are regulated in real time. In the embodiment, the cooling devices are respectively arranged at the welding head and the ultrasonic transducer for cooling treatment so as to improve the cooling effect. The cooling mechanism at the horn is defined as a first cooling mechanism and the cooling mechanism at the ultrasonic transducer is defined as a second cooling mechanism.
Preferably, a first cooling parameter of a first cooling mechanism positioned at the welding head is set according to the sewing sequence; a safe temperature interval of the ultrasonic transducer is obtained in advance, and a second cooling parameter of a second cooling mechanism positioned at the ultrasonic transducer is set based on the safe temperature interval; adjusting parameters of a first cooling mechanism according to the real-time temperature of the welding head by taking the first cooling parameters as references; and adjusting parameters of the second cooling mechanism according to the real-time temperature at the ultrasonic transducer by taking the second cooling parameters as references. The first cooling parameter and the second cooling parameter are equivalent to normal parameters of the cooling mechanism, and when the temperature fluctuates, the parameters only need to float up and down.
The present embodiment optimizes the setting of the cooling mechanism in view of the particularities of the ultrasonic transducer and the possible effects of vibration on the weld. Specifically, a supporting plate is suspended and erected at the joint of the welding head and the ultrasonic transducer, so that the supporting plate is not contacted with the welding head and the ultrasonic transducer; analyzing whether the first cooling mechanism can influence the vibration frequency of the welding head when the first cooling mechanism operates at the maximum power so as to set a safe distance between the first cooling mechanism and the welding head; the first cooling mechanism is arranged on the supporting plate, and the minimum distance between the first cooling mechanism and the welding head is not smaller than the safety distance; constructing a semi-closed space surrounding the ultrasonic transducer based on the supporting plate, wherein the semi-closed space is suspended around the ultrasonic transducer, and one end of the ultrasonic transducer extends out of the semi-closed space to be connected with the welding head; the second cooling mechanism frame is arranged on one or more side surfaces of the semi-enclosed space, and the preset air outlet and the cooling mechanism are arranged on two opposite side surfaces. The semi-enclosed space is arranged to protect the ultrasonic transducer, so that the heat in the ventilation space of the air outlet needs to be set.
Illustratively, a plurality of cooling devices are set in the second cooling mechanism, so that the second cooling mechanism has a plurality of levels of cooling modes, and each level of cooling mode corresponds to a temperature interval of a group of ultrasonic transducers; and selecting a cooling mode with a corresponding grade according to a temperature interval to which the real-time temperature of the ultrasonic transducer belongs. The second cooling mechanism is located at the ultrasonic transducer, which generates a higher heat generation amount, and thus requires a plurality of levels of cooling modes. In fig. 3, the second cooling mechanism includes two cooling fans. Likewise, the cooling level may also be set for the first cooling mechanism.
The embodiment provides an intelligent planning method for an ultrasonic sewing business process, which is used for sewing clothes compounded by multiple melting point materials according to the sewing temperature from low to high and then to low, ensuring that each sewing is performed under the optimal temperature condition, fully utilizing the temperature characteristic of an ultrasonic assembly, and reducing the shutdown and repair time caused by temperature abnormality, thereby improving the sewing quality and sewing efficiency.
