Technical Field
[0001] This utility model belongs to the field of dryer manufacturing technology, specifically an ultrasonic riveting device for the production of glass door components for dryers. Background Technology
[0002] In dryer product design, the glass door not only serves a protective function, but its aesthetic appeal is also increasingly valued. To enhance the product's appearance and visual appeal, dryer glass doors are often decorated with glass of different shapes, such as circles, ovals, and irregular shapes. These diverse glass shapes give dryer glass doors a unique appearance, satisfying consumers' demands for product personalization. However, this design innovation also presents challenges to the production of dryer glass door frames. During the production process, to accommodate different glass shapes, the dryer glass door frame needs to have matching mounting grooves, resulting in a variety of mounting groove shapes.
[0003] Meanwhile, the isolation ring assembly is a major component of the dryer's glass door frame, serving both aesthetic and functional control purposes. The isolation ring assembly consists of an outer ring and an isolation ring. Traditionally, the connection between the outer ring and the isolation ring is achieved through hot riveting. This involves using a pre-installed plastic rivet on a component, with an electric heating plate transferring heat to the hot riveting head. The hot riveting head heats the rivet, melting it, and then blowing it up to cool and solidify it, forming an arc-shaped flanged rivet head to secure the product.
[0004] However, existing ultrasonic riveting devices typically use bolts to fix the positioning molds. This fixing method has obvious drawbacks when producing frames for different shaped glass. Every time the outer ring and isolation ring of the dryer glass door frame are changed for welding, a lot of time needs to be spent disassembling and installing the positioning molds. The operation is cumbersome and results in low production efficiency. Utility Model Content

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] Example 1:
[0029] Please see Figures 1-6 This application provides an ultrasonic riveting device for the production of glass door components for dryers, including an ultrasonic hot riveting machine body 1 and an ultrasonic hot riveting unit 2 disposed on the ultrasonic hot riveting machine body 1, used for ultrasonic hot riveting welding of the glass door frame of a washing machine. The ultrasonic hot riveting unit 2 consists of a moving component and an ultrasonic hot riveting component. The moving component is used to drive the ultrasonic hot riveting component to move along the longitudinal and transverse axes in a planar coordinate system, preferably with the cooperation of a linear guide rail and a slider 10, which is prior art and will not be elaborated further. The ultrasonic hot riveting component is also prior art, used only for ultrasonic riveting of the glass door frame of a dryer. A support platform 3 is movably mounted on the ultrasonic hot riveting machine body 1. The purpose of the support platform 3 movably mounting on the ultrasonic hot riveting machine body 1 is to enable the support platform 3 to drive the glass door frame of the dryer on it to move upwards in the direction of the ultrasonic hot riveting unit 2 on the ultrasonic hot riveting machine body 1. Combined with the movement direction of the ultrasonic hot riveting unit 2 itself, this allows for ultrasonic riveting of the glass door frame of the dryer. The frame of the machine glass door is hot-riveted at any position. A placement platform 4 is provided on the support platform 3. A pre-made groove is opened inside the placement platform 4. A wedge block 6 is slidably arranged inside the pre-made groove. A first sliding groove 8 is provided on each of the two side walls of the wedge block 6. A slider 10 is slidably connected inside the first sliding groove 8. An insert rod 9 is fixedly connected to the slider 10. A positioning mold 15 is provided above the placement platform 4. The shape of the positioning mold 15 is set to match the specific shape of the glass embedded in the frame of the dryer door. An installation frame 13 is provided on the bottom surface of the positioning mold 15. It should be noted that the installation frame 13 can be installed on the positioning mold 15 during the production process. The installation frame 13 is provided with a first slot 14 that cooperates with the insert rod 9. Specifically, when the installation frame 13 is inserted into the second slot 23 on the placement platform 4, the insert rod 9 slides into the first slot 14 to complete the positioning and installation of the positioning mold 15.
[0030] A pull rod 5 is rotatably connected above the wedge block 6 and passes through the placement platform 4, and a limit rod 22 is provided on the pull rod 5;
[0031] The top surface of the placement platform 4 is also fixedly connected to a sleeve post 11 arranged outside the tie rod 5, and the sleeve post 11 is provided with a guide groove 12 for the insertion of the limiting rod 22.
[0032] The precast groove is also equipped with a spring 7 arranged between the placement platform 4 and the wedge block 6, which is used to reset the wedge block 6.
[0033] The end of the insertion rod 9 that contacts the wedge block 6 is provided with a slope that is adapted to it, and the other end of the insertion rod 9 is also a slope.
[0034] Specifically, by inserting the mounting bracket 13 containing the positioning mold 15 into the interior of the second slot 23, the end of the mounting bracket 13 presses against the insertion rod 9, causing the insertion rod 9 to move towards the wedge block 6. Due to the first sliding groove 8 and the slider 10, the wedge block 6 is compressed and moves downwards. Meanwhile, the limiting rod 22 on the pull rod 5 slides downwards along the guide groove 12. When the insertion rod 9 is directly aligned with the first slot 14 on the mounting bracket 13, the limiting rod 22 is pulled upwards to directly above the sleeve post 11. Simultaneously, under the action of the spring 7, the wedge block 6 is reset, and the insertion rod 9 also moves accordingly. The device is reset, but at this time the insertion rod 9 can be inserted into the inside of slot 14, and the mounting bracket 13 is limited to be installed inside slot 23. Then the limiting rod 22 is rotated to make the limiting rod 22 and the sleeve 11 misaligned, that is, to position the wedge block 6, thereby realizing the quick installation of the positioning mold 15. It can replace the mold with the same as the preset glass in time, so that the positioning mold 15 fits into the connection between the dryer glass door frame and the glass, and plays a positioning role. This changes the problem that the existing positioning mold 15 is generally fixed by bolts, which makes it inconvenient to disassemble the positioning mold 15 when hot riveting different types of dryer glass door frames.
[0035] Example 2:
[0036] Based on Embodiment 1, a plurality of sliding seats 18 arranged in a circular array are provided above the support platform 3, and clamping and limiting components are provided on the sliding seats 18.
[0037] The clamping and limiting assembly includes a drive shaft rotatably connected to the sliding seat 18, and a drive component, specifically a mini motor 20, is provided at the end of the drive shaft to drive the drive shaft to rotate. A connecting frame 19 is fixedly connected to the drive shaft, and a rubber pressure block 21 is provided at the end of the connecting frame 19 away from the drive shaft. In order to facilitate the clamping and fixing of the glass door frame of the dryer, the rubber pressure block 21 is preferably made of rubber, which is economical and environmentally friendly. It can not only increase the friction between the rubber and the glass door frame of the dryer, but also will not damage the glass door frame of the dryer due to its material properties.
[0038] The main body 1 of the ultrasonic hot riveting machine is provided with several second slide grooves 16 that match the sliding seat 18, and the bottom of the sliding seat 18 is slidably connected to the inside of the second slide groove 16. Each second slide groove 16 is provided with a driving component for driving the sliding seat 18 to move, specifically a cylinder 17. The cylinder 17 is an existing product and is only used to drive the sliding seat 18 to move.
[0039] The rubber block 21 is located above the placement platform 4, and the placement platform 4 is located outside the positioning mold 15.
[0040] Specifically, the cylinder 17 pushes the sliding seat 18 to move inside the second slide groove 16, and the rubber pressure block 21 clamps and fixes the glass door frame of the dryer. This allows the position of the clamping and limiting component to be adjusted according to the size of the glass door frame of the dryer, and the glass door frame of the dryer to be fixed by the clamping and limiting component, ensuring the stability during hot riveting welding.
[0041] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
