Description

Technical Field

[0001] The present invention relates to the technical field of bonding devices, and more specifically to an automated material bonding device and method thereof. Background Art

[0002] A material bonding device realizes the bonding of materials by applying a certain pressure and temperature to the materials, causing the surfaces of the materials to melt, flow, and solidify. Existing bonding devices include ultrasonic welding machines and sealing machines. During the production of baby pull-up diaper materials, an ultrasonic welding machine is used to bond the pull-up diaper materials. Inside a roller-type ultrasonic welding machine, there is an ultrasonic generator that converts industrial-frequency alternating current into high-frequency alternating current. This high-frequency electrical signal is transmitted to the ultrasonic transducer. When the high-frequency electrical signal acts on the piezoelectric ceramic, the piezoelectric ceramic generates high-frequency telescopic vibrations. The frequency of this vibration is the same as the frequency of the input electrical signal. Then, the vibration is transmitted to the roller-shaped welding head. When the welding wheel rolls on the surface of the workpiece, the ultrasonic vibration energy is transmitted to the contact surface of the workpiece through the welding wheel. Under the combined action of ultrasonic vibration and a certain pressure, the molecules on the surface of the workpiece start to vibrate violently, generating frictional heat. This frictional heat causes the materials on the surface of the workpiece to rapidly heat up to near the melting point, the materials undergo plastic deformation, and the molecules penetrate and diffuse into each other. As the welding wheel rolls, the welding area continuously expands, and finally a firm connection between the workpieces is achieved.

[0003] For example, a carbon fiber ultrasonic sealing machine with the publication number CN209177039U in the prior art uses the vibration principle of ultrasonic waves to perform a series of processing operations such as edge sewing, fusion welding, fusion cutting, and embossing on the workpieces passing through it by an ultrasonic welding roller. The ultrasonic welding roller can perform edge sewing and fusion welding on the workpieces.

[0004] However, the above prior art still has the following problems when in use: When bonding the pull-up diaper materials, it is necessary for the staff to manually adjust the position of the materials and hold the materials for bonding. However, due to the softness of the materials, during the advancing process, the materials are prone to shift, affecting the straightness of the bonding. At the same time, due to the rotation of the welding roller, the staff's palm is easily touched by the welding roller and injured, with low safety. Based on this, the present invention provides an automated material bonding device and method thereof. Summary of the Invention

By measuring the distance between the limit plate and the welding roller with a scale, it is convenient to accurately adjust the position of the limit plate. The limit plate and the limit roller are used in cooperation to limit the pull-up diaper materials, thereby further improving the bonding effect of the pull-up diaper materials. Then, the ultrasonic generator, the ultrasonic transducer, and the welding roller cooperate to achieve continuous welding of the pull-up diaper materials, so as to solve the problems presented in the above background art.

[0041] A limiting assembly 5 is fixedly provided on the top of the welding table 31. The limiting assembly 5 includes a limiting plate 51. Two connecting plates 52 are provided on the top of the limiting plate 51. The two connecting plates 52 are respectively disposed in front of and behind the welding roller 33. A plurality of limiting rollers 53 are rotatably provided on one side of each of the two connecting plates 52. The connecting plates 52 are fixed to the top of the limiting plate 51 by electric push rods one 54. Moreover, two sliders 55 are fixedly provided on one side of the limiting plate 51 away from the welding roller 33. Two sliding grooves 56 are machined on the top of the welding table 31. The sliders 55 are slidably disposed in the sliding grooves 56. Threaded fasteners 57 are connected to the tops of the two sliders 55. The bottom of the threaded fastener 57 abuts against the inner wall of the sliding groove 56. A scale 58 is fixedly embedded in the top of the welding table 31. The distance between the limiting plate 51 and the welding roller 33 can be accurately adjusted through the scale 58.

[0042] A supporting assembly 6 is fixedly provided at the bottom of the processing tabletop 1. Specifically, the supporting assembly 6 includes a supporting frame 61. Receiving grooves 62 are formed on both sides of the top of the supporting frame 61. Electric push rods four 63 are fixedly provided inside the two receiving grooves 62.

[0043] A foot switch 15 is fixedly provided on the top of the supporting frame 61. The number of the foot switches 15 is multiple. The multiple foot switches 15 are respectively used to control the electric push rod one 54, the electric push rod two 47, the stepping motor 45, the ultrasonic generator 43, and the ultrasonic transducer.

[0044] In actual use, first, according to the welding position of the pull-up diaper material, loosen the fastening bolts 57 on the two sliders 55, then use the scale 58 to measure the distance between the left side of the limit plate 51 and the right side of the welding roller 33, precisely adjust the position of the limit plate 51, and then tighten the fastening bolts 57. Then, use the foot switch 15 to control the first electric push rod 54 to extend, driving the connecting plate 52 and the multiple limit rollers 53 to move upward, so that the limit rollers 53 are away from the welding table 31. Place the pull-up diaper material on the welding table 31, and make the right end of the pull-up diaper material abut against the left side of the limit plate 51. Then, use the limit rollers 53 to move downward and press on the pull-up diaper material. Then, use the foot switch 15 to control the second electric push rod 47 to extend, driving the mounting bracket 41 to move downward. After pressing the welding roller 33 on the surface of the pull-up diaper material, start the ultrasonic generator 43. The ultrasonic generator 43 generates high-frequency electrical signals and transmits them to the ultrasonic transducer 44 through the connecting wire. The ultrasonic transducer 44 converts the electrical signals into ultrasonic vibrations. The ultrasonic vibrations are transmitted by the ultrasonic transducer 44 to the welding roller 33. The welding roller 33, driven by the sprocket group 46 and the stepping motor 45, rotates while transmitting ultrasonic energy to the pull-up diaper material, causing the molecules on its surface to vibrate violently and generate frictional heat, rapidly raising the temperature of the surface of the pull-up diaper material to the melting point or reaching the viscous flow state. The welding roller 33 applies a certain pressure to prompt the pull-up diaper material to come into close contact and fuse together. As the welding roller 33 and the support roller 10 roll, the pull-up diaper material moves continuously backward, thereby achieving continuous welding.

[0045] Refer to the attached drawings of the specification Figures 1-3 , Figure 5 and Figure 9 , a rectangular groove 7 is also opened on one side of the top of the welding table 31. An installation plate 8 is fixedly arranged inside the rectangular groove 7. A servo motor 9 is fixedly arranged inside the installation plate 8. A support roller 10 is fixedly sleeved on the output shaft of the servo motor 9. The support roller 10 is arranged below the welding roller 33. By cooperating the support roller 10 with the welding roller 33, the pull-up diaper material can be driven to move stably, thereby improving the welding straightness of the pull-up diaper material.

[0046] Moreover, lifting plates 12 are fixedly arranged on both sides of the welding table 31. Two electric push rods three 13 are fixedly arranged at the bottom ends of the two lifting plates 12. The two electric push rods three 13 are fixedly connected to the bottom of the processing table 1 through fixing plates 14. By driving the welding table 31 to lift through the electric push rods three 13, it is convenient for the staff to disassemble the installation plate 8 and replace the servo motor 9 and the support roller 10 on the installation plate 8.
