Technical Field

[0001] The present application relates to the technical field of glue pressing and welding, and in particular, to a glue pressing and welding method and a glue pressing and welding device. Background Art

[0002] Ultrasonic welding converts 220 volts, 50 Hz or 60 Hz into 15 KHz, 20 KHz, 30 KHz or 40 KHz electrical energy. The converted high-frequency electrical energy is converted again into mechanical motion of the same frequency through a transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude transformers such as transducers that can change the amplitude. The welding head transmits the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy through friction to melt the plastic. The compression welding method uses ultrasonic welding to weld the zipper chain and tape together through the plastic workpiece. In the traditional compression welding method, the ultrasonic welding machine outputs ultrasonic waves in a time mode as the welding mode, resulting in insufficient consistency in compression welding and poor quality of compression welding.

[0029] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0030] Embodiment 1

[0031] like Figure 1 As shown, the adhesive bonding method of the embodiment of the present application includes the following steps:

[0032] Step S100: the ultrasonic welding machine outputs ultrasonic waves in an energy mode as a welding mode, and the ultrasonic energy output by the ultrasonic welding machine is within a preset range;

[0033] Step S200: amplifying the ultrasonic amplitude output by the ultrasonic welding machine by a preset ratio and then outputting the ultrasonic wave with the amplitude changed;

[0034] Step S300: The welding head descends to the lower mold for welding, and the welding head transmits the ultrasonic wave after amplitude change to the lower mold, and welds the two plastic workpieces, the zipper chain and the tape located above the lower mold and below the welding head together.

[0035] In the glue welding method of the embodiment of the present application, the ultrasonic welding machine outputs ultrasonic waves in an energy mode, which can achieve the consistency of the ultrasonic output energy output by the ultrasonic welding machine each time, so that the consistency of each glue welding is strong. The ultrasonic amplitude is amplified by a preset ratio. The welding head descends to the lower mold for welding, and the welding head transmits the ultrasonic wave after the amplitude is changed to the lower mold, and welds the two plastic workpieces located above the lower mold and below the welding head, the zipper chain and the tape together. The core of the glue welding that welds the plastic workpiece, the zipper chain and the tape together is energy. In the glue welding method of the embodiment of the present application, the ultrasonic welding machine adopts an energy mode, which can ensure that the ultrasonic welding machine releases constant energy stably throughout the process of glue welding; and can also ensure that the amplitude meets the requirements of glue welding. The quality of glue welding is stable, which improves the firmness of the chain and the tape fixed together, and ensures the water washing performance and physical properties.

[0036] During the implementation, the steps of lowering the welding head to the lower die for welding specifically include:

[0037] During the welding head descending stage, the difference between the actual descending air pressure output by the control cylinder and the descending target air pressure is less than or equal to the preset error value of the descending air pressure;

[0038] During the welding stage of the welding head, the difference between the actual welding gas pressure output by the control cylinder and the welding target gas pressure is less than or equal to the preset error value of the welding gas pressure;

[0039] Among them, the cylinder is used to provide the pressure required for the welding head to descend and weld. The descending target pressure is greater than the welding target pressure. The descending target pressure is the target pressure output by the cylinder during the welding head descending stage, and the welding target pressure is the target pressure output by the cylinder during the welding head welding stage.

[0040] The descending target pressure is greater than the welding target pressure, so that the target of the up and down reciprocating motion of the welding head includes a faster descending speed of the welding head, so as to achieve a rapid descent of the welding head; the target of the up and down reciprocating motion of the welding head also includes that when the welding head is welded, the welding target pressure is set according to the requirements of the glue welding process. Through the cooperation of the pressure sensor and the proportional valve, the output of the cylinder is feedback controlled so that the actual descending pressure output by the cylinder is as close to the descending target pressure as possible, and the actual welding pressure output by the cylinder is as close to the welding target pressure as possible.

[0041] In implementation, the preset range of the ultrasonic energy is any value greater than or equal to 250 joules and less than or equal to 300 joules;

[0042] Alternatively, the preset range of the ultrasonic energy is 280 joules.

[0043] In implementation, the preset ratio of the transducer amplitude amplification is any value greater than or equal to 2.25 and less than or equal to 2.5;

[0044] Alternatively, the preset ratio of the transducer amplitude amplification is 2.25.

[0045] In implementation, the welding target gas pressure is any value greater than or equal to 0.1 MPa and less than or equal to 0.3 MPa; the descending target gas pressure is any value greater than or equal to 0.4 MPa and less than or equal to 0.6 MPa;

[0046] Alternatively, the welding target gas pressure is 0.2 MPa; and the descending target gas pressure is 0.5 MPa.

[0048] like Figure 2 , Figure 3 and Figure 4 As shown, the adhesive bonding device of the embodiment of the present application includes:

[0049] Transducer 110;

[0050] A welding head 120 is fixed to the lower end of the output shaft of the transducer 110;

[0051] An ultrasonic welding machine, connected to the transducer 110, the ultrasonic welding machine is used to output ultrasonic waves in an energy mode as a welding mode, and the ultrasonic energy output by the ultrasonic welding machine is within a preset range;

[0052] Among them, the transducer 110 amplifies the ultrasonic amplitude output by the ultrasonic welding machine by a preset ratio and outputs the ultrasonic wave with modified amplitude; the welding head 120 descends to the external lower mold for welding, and the welding head 120 transmits the ultrasonic wave with modified amplitude to the lower mold to weld the plastic workpiece, the zipper chain and the tape located above the lower mold together.

[0053] In the glue welding device of the embodiment of the present application, the ultrasonic welding machine outputs ultrasonic waves in an energy mode, which can achieve the consistency of the ultrasonic output energy output by the ultrasonic welding machine each time, so that the consistency of each glue welding is strong. The ultrasonic amplitude is amplified by a preset ratio through a transducer. The welding head descends to the lower mold for welding, and the welding head transmits the ultrasonic wave after amplitude change to the lower mold, and welds the plastic workpiece, the zipper chain and the tape located above the lower mold and below the welding head together. The core of the glue welding that welds the plastic workpiece, the zipper chain and the tape together is energy. In the glue welding device of the embodiment of the present application, the ultrasonic welding machine adopts an energy mode, which can ensure that the ultrasonic welding machine releases constant energy stably throughout the process of glue welding; the transducer can also ensure that the amplitude meets the requirements of glue welding. The quality of glue welding is stable, which improves the firmness of the chain and the tape fixed together, and ensures the water washing performance and physical properties.

[0054] In implementation, such as Figure 2As shown, the glue pressing welding device also includes:

[0055] The cylinder 400 is used to provide the pressure required for the welding head 120 to descend and weld;

[0056] A pressure sensor 410 is provided at the output end of the cylinder 400 and is used to sense the actual output pressure of the cylinder;

[0057] A proportional valve is connected to the cylinder and the pressure sensor, and is used to control the output ratio of the cylinder; the proportional valve is used to control the difference between the actual descending air pressure output by the cylinder and the descending target air pressure to be less than or equal to the preset error value of the descending air pressure during the welding head descending stage; the proportional valve is also used to control the difference between the actual welding air pressure output by the cylinder and the welding target air pressure to be less than or equal to the preset error value of the welding air pressure during the welding head welding stage;

[0058] Among them, the descending target air pressure is the target air pressure output by the cylinder during the descending stage of the welding head, and the welding target air pressure is the target air pressure output by the cylinder during the welding stage of the welding head. The descending target air pressure is greater than the welding target air pressure.

[0059] The descending target pressure is greater than the welding target pressure, so that the target of the up and down reciprocating motion of the welding head includes a faster descending speed of the welding head, so as to achieve a rapid descent of the welding head; the target of the up and down reciprocating motion of the welding head also includes that when the welding head is welded, the welding target pressure is set according to the requirements of the glue welding process. Through the cooperation of the pressure sensor and the proportional valve, the output of the cylinder is feedback controlled so that the actual descending pressure output by the cylinder is as close to the descending target pressure as possible, and the actual welding pressure output by the cylinder is as close to the welding target pressure as possible.

[0060] Embodiment 3

[0061] The glue pressing welding device of the embodiment of the present application has the following features based on the second embodiment.

[0062] During implementation, the glue welding device also includes:

[0063] An adjustment seat, to which the transducer is fixed;

[0064] A fixing seat, the adjusting seat is installed below the fixing seat;

[0065] An adjustment component is connected to the adjustment seat and the fixed seat, and the adjustment component is used to adjust the angle of the adjustment seat relative to the fixed seat, so as to adjust the angle of the welding head relative to the fixed seat.

[0066] Specifically, the transducer, the welding head, the adjustment seat, the fixing seat and the adjustment assembly constitute a welding head assembly. The welding head assembly can reciprocate up and down during the adhesive bonding process.

[0067] The glue-pressed welding device of the embodiment of the present application includes a welding head assembly, and the welding head assembly includes a transducer, a welding head, an adjustment seat, a fixed seat and an adjustment assembly. The transducer, the welding head and the adjustment seat are fixed together, and the fixed relationship is that the welding head is fixed to the lower end of the output shaft of the transducer, and the adjustment seat is fixed to the transducer. The adjustment seat is installed below the fixed seat, and the adjustment assembly connects the adjustment seat and the fixed seat. The angle of the adjustment seat relative to the fixed seat can be adjusted by the adjustment assembly, thereby adjusting the angle of the welding head relative to the fixed seat. The function of the fixed seat is to fix the entire welding head assembly. After the fixed seat fixes the entire welding head assembly, the angle of the adjustment seat relative to the fixed seat can be adjusted by adjusting the elements in the assembly, so that the angle of the transducer and the welding head fixed as one with the adjustment seat relative to the fixed seat can be adjusted, that is, after the welding assembly is fixed, the angle of the welding head can be adjusted. The glue-pressed welding device of the embodiment of the present application, through a welding assembly with a simple structure, can realize that after the welding assembly is fixed by the fixed seat, the welding head can adjust the angle by adjusting the assembly, so that the difficulty of adjusting the welding head is relatively small, and the requirements for the adjustment personnel are relatively low.

[0068] In implementation, such as Figure 2 As shown, the fixing seat comprises a U-shaped fixing seat horizontal plate 141 and two fixing seat vertical plates 142, and the two fixing seat vertical plates 142 are fixed on the outer sides of the two arms of the fixing seat horizontal plate 141;

[0069] The adjustment seat comprises:

[0070] Two adjustment seat transverse plates 131, the two adjustment seat transverse plates 131 are respectively installed on the inner sides of the two fixed seat vertical plates 142, and the two adjustment seat transverse plates 131 are arranged opposite to each other and have a gap;

[0071] An adjustment seat fixing ring 132, the adjustment seat fixing ring 132 is fixed to the outer peripheral surface of the output shaft of the transducer 110, and is fixed on the two adjustment seat transverse plates 131; wherein the output shaft of the transducer 110 is located at the interval between the two adjustment seat transverse plates 131;

[0072] The adjustment assembly includes an adjustment screw 151 , and the adjustment screw 151 passes through an adjustment threaded hole reserved on the fixing seat transverse plate 141 and abuts against the adjustment seat transverse plate 131 .

[0073] The opening of the U-shaped fixing seat horizontal plate is used to provide a space for accommodating the output shaft of the transducer and the fixing ring of the adjustment seat, and the fixing seat vertical plate serves as the installation base of the adjustment seat.

[0074] The two adjustment seat transverse plates are respectively installed on the inner sides of the two fixed seat vertical plates, arranged oppositely and with a gap. In this way, the gap between the two adjustment seat transverse plates provides space for the output shaft of the transducer to pass through, and at the same time, the two adjustment seat transverse plates are used as a fixing base for the adjustment seat fixing ring. When the glue dispensing position is relatively shallow, turn the adjustment screw at this position downward to apply a downward force to the adjustment seat transverse plate, so that the adjustment seat transverse plate can produce a small range of inclination, thereby achieving the adjustment of the adjustment seat transverse plate, and then the adjustment seat fixing ring fixed thereto produces a small range of inclination, thereby causing the welding head to have a small range of inclination. When the glue dispensing position is relatively high, turn the adjustment screw at this position upward, and the glue dispensing will push the adjustment screw to move upward.

[0075] In implementation, such as Figure 2 As shown, there are four adjusting screws 151;

[0076] One threaded hole for adjustment is reserved at each of the four corners of the fixed seat transverse plate 141 , and the four adjustment screws 151 pass through the four threaded holes for adjustment and abut against the adjustment seat transverse plate.

[0077] In this way, the welding head can be tilted and adjusted in a small range in four directions through four adjustment screws.

[0078] In implementation, such as Figure 2 and Figure 3 As shown, the glue pressing welding device also includes:

[0079] Four pairs of mounting screws 160, two pairs of mounting screws 160 respectively pass through the fixing seat vertical plates 142 and penetrate into the two arms of the fixing seat horizontal plate 141, and fix the two fixing seat vertical plates 142 on the outer sides of the arms of the fixing seat horizontal plate 141; thus, the two fixing seat vertical plates are fixed on the outer sides of the two arms of the fixing seat horizontal plate;

[0080] Two pairs of mounting screws 160 respectively pass through the fixed seat vertical plate 142 and penetrate into the two adjustment seat horizontal plates 131; thus, the two adjustment seat horizontal plates are respectively fixed to the inner sides of the two fixed seat vertical plates.

[0081] The adjustment seat horizontal plate is installed on the inner side of the fixed seat vertical plate by installing screws, and the adjustment screws are used for adjustment, so that the adjustment range through the adjustment screws is small, generally the adjustment range is greater than or equal to 0.01 mm and less than or equal to 0.02 mm.

[0082] Specifically, Figure 2As shown, the adjustment seat transverse plate 131 is a stepped adjustment seat transverse plate, and the higher side of the adjustment seat transverse plate 131 is fixed to the fixed seat vertical plate 142 , and the adjustment seat fixing ring 132 is fixed to the lower side of the adjustment seat transverse plate 131 .

[0083] The step-shaped adjusting seat transverse plate has a simple structure and provides a fixing space for the adjusting seat fixing ring.

[0090] The welding head body of the welding head is provided with a heat dissipation channel, and the heat dissipation channel is parallel to the welding head texture, so that the cooling airflow providing device cools the cooling airflow through the heat dissipation channel through the pipeline. The heat dissipation channel is provided in the welding head to directly cool the welding head, and the cooling of the welding head is more efficient.

[0093] The upper end portion 122 - 2 of the welding head body has at least one heat dissipation channel 121 .

[0094] The closer to the welding head pattern, the higher the temperature and the higher the need for heat dissipation. Therefore, more heat dissipation channels are provided at the lower end of the welding head body.

[0095] In implementation, such as Figure 4 As shown, the welding head pattern includes:

[0096] A plurality of straight lines 123-1, wherein the straight lines 123-1 are arranged at intervals around the end of the lower end portion of the welding head body;

[0097] A plurality of diagonal lines 123 - 2 are formed in the surrounding straight lines, and the diagonal lines are formed by a plurality of diagonal line protrusions arranged at intervals.

[0098] The method of straight lines on all sides and diagonal lines in the middle is adopted, which ensures the beauty of the welding lines formed by the welding head lines.

[0099] In implementation, the angle between the length direction of the twill and the length direction of the straight grain is greater than or equal to 30 degrees and less than or equal to 60 degrees;

[0100] The intervals between the straight lines are greater than or equal to 0.25×1.41 mm and less than or equal to 0.35×1.41 mm, the intervals between the diagonal lines are greater than or equal to 0.25 mm and less than or equal to 0.35 mm, and the intervals between the diagonal line bumps are greater than or equal to 0.25 mm and less than or equal to 0.35 mm.

[0101] The welding lines formed by the welding head lines are beautiful, and the effect of water washing and ironing of the welding lines formed by the welding head lines is also guaranteed.

[0102] Specifically, the angle between the length direction of the twill and the length direction of the straight grain is 45 degrees;

[0103] The intervals between the straight lines are 0.3×1.41 mm, the intervals between the diagonal lines are 0.3 mm, and the intervals between the diagonal protrusions are 0.3 mm.

[0104] like Figure 5 As shown, the interval between the oblique protrusions is L, and the interval between the straight lines is 1.41L.

[0105] In this way, the intervals between the straight lines are larger than the intervals between the oblique protrusions, and the intervals between the straight lines can conduct away the heat in the intervals between the oblique protrusions.

[0106] The welding lines formed by the welding head lines are beautiful, and the effect of water washing and ironing of the welding lines formed by the welding head lines is also guaranteed.

[0112] The base and support frame are the installation foundation of the entire glue welding device. The cylinder is used as the power device for the vertical plate to reciprocate up and down, so that the vertical plate reciprocates up and down along the guide groove, so that the welding head assembly fixed to the vertical plate also reciprocates up and down as a whole.

[0113] In implementation, such as Figure 2 and Figure 3 As shown, the glue pressing welding device also includes:
