Detailed implementation manners

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] Embodiment 1:

[0054] When producing a cover plate structure of a certain model, in order to reduce production costs and improve production efficiency, a production process of separately producing the plate parts and fasteners is adopted; the plate parts are large in area and have a large amount of material (cover plates with a length and width both exceeding 1M), and a rolling forming process is used to produce the raw materials and cut them into plate parts of a predetermined size. The fasteners adopt an efficient injection molding process with multiple parts in one mold, and later an ultrasonic automatic welding device is used for welding and assembling. This process can improve production efficiency, avoid using super-large molds, and reduce production costs. Based on this production process, an embodiment of the present invention provides an ultrasonic automatic welding device for ultrasonic welding of plate part 1 and fastener 10 to produce the cover plate structure, such as Figures 1-12 shown. The ultrasonic automatic welding device includes: a base 4, a side frame 2, an ultrasonic welding module 3, a rotating shaft 6, a feeding tray 7, a feeding component 8, and a positioning seat 9.

[0055] A rotating shaft 6 is rotatably installed in the base 4. The rotating shaft 6 is precisely controlled by a servo motor 5 / external power to rotate the angle (for example, the plate part 1 uses an intelligent operation console, and the rotating shaft 6 is linked with the power equipment of the intelligent operation console). A feeding tray 7 is fixedly installed on the rotating shaft 6. The feeding tray 7 includes at least two working stations. A positioning seat 9 is installed at the first working station among the two working stations, and a feeding component 8 is installed at the second working station among the two working stations. The feeding component 8 and the feeding tray 7 cooperate to transfer the fastener 10 to the positioning seat 9. A side frame 2 is fixedly installed on one side of the base 4, and the ultrasonic welding module 3 is fixedly installed on the side surface of the side frame 2.

[0056] When in use, the plate part 1 is manipulated manually / by an intelligent operation console, and the fastener 10 is placed in the vibrating feeder. The end 11 of the vibrating feeder is connected to the feeding component 8. The feeding component 8 and the feeding tray 7 cooperate to transfer the fastener 10 to the positioning seat 9. The plate part 1 is located on the tabletop above the base 4. After the position is confirmed, the ultrasonic welding module 3 operates to perform ultrasonic welding of the plate part 1 and the fastener 10.

[0057] Specifically, the positioning seat 9 includes: a main body block 901. A positioning port is arranged on the side surface of the main body block 901. The positioning port has a guiding inclined surface 903 and a guiding vertical surface 904 located at the top of the guiding inclined surface 903. A cross block 905 is fixedly installed at the guiding vertical surface 904. The guiding inclined surface 903 is parallel to the inclined surface of the fastener 10. When the fastener 10 is pushed towards the guiding inclined surface 903, it can move obliquely upward based on the guidance of the guiding inclined surface 903. The top end of the fastener 10 exposes the platform at the top of the base 4, and the top end of the fastener 10 contacts the bottom surface of the plate part 1. When the ultrasonic welding module 3 presses down, the upper part of the side port of the fastener 10 abuts against the upper part of the cross block 905 to realize the positioning and fixation of the fastener 10. The ultrasonic welding module 3 generates ultrasonic vibration and pressure to weld the plate part 1 and the fastener 10 together.

[0058] In one embodiment, the base 4 includes a main shell 4b and a motor shell 4a which are distributed up and down. A mounting plate 4c is fixedly connected to the inner side of the main shell 4b. The mounting plate 4c needs to bear weight. A beam frame can be designed for auxiliary support at the connection between the main shell 4b and the mounting plate 4c. The rotating shaft 6 is rotatably installed on the mounting plate 4c through a bearing. The top end of the rotating shaft 6 is located inside the main shell 4b, and the bottom end of the rotating shaft 6 is located inside the motor shell 4a. A servo motor 5 is fixedly installed on the inner side of the motor shell 4a. The top output end of the servo motor 5 is connected to the bottom end of the rotating shaft 6 through a coupling. The loading tray 7 is located in the main shell 4b above the mounting plate 4c. The servo motor 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 rotates synchronously with the loading tray 7 to switch the working position of the loading tray 7.

[0059] In one embodiment, the fastener 10 is an iron plastic-coated part, and the structure of the loading tray 7 can be designed by magnetic attraction. The specific loading tray 7 includes: a cylinder shell 701, a cover body 702, a magnetic ejection assembly 704, and a guide frame 703.

[0060] The top end of the barrel shell 701 is open, so it is convenient to install the magnetic pop-up component 704 inside the barrel shell 701, and the cover body 702 is fixedly installed at the top end opening of the barrel shell 701. The cover body 702 and the barrel shell 701 form an annular cavity structure, and the magnetic pop-up component 704 is fixedly installed on the inner side of the barrel shell 701. The length direction of the magnetic pop-up component 704 is arranged along the radial direction of the barrel shell 701. There are multiple magnetic pop-up components 704, and the multiple magnetic pop-up components 704 are distributed in a ring array. The guide frame 703 is fixedly connected to the base 4 through the bracket. The bracket should be designed on the outside of the guide frame 703 to avoid affecting the coordination between the guide frame 703 and the magnetic pop-up component 704, and the guide frame 703 is located below the barrel shell 701. The guide frame 703 is used to guide the magnetic pop-up component 704 to be retracted and popped out at the first working station.

[0061] like Figure 8 As shown in the figure, the barrel shell 701 will rotate with the rotating shaft 6, and the magnetic pop-up component 704 will also rotate accordingly, constantly switching the position of the magnetic pop-up component 704, and the guide frame 703 is fixedly connected to the base 4 through the bracket (the guide frame 703 does not rotate), and the guide frame 703 controls the retraction action of guiding the magnetic pop-up component 704, which includes two processes: 1. During the rotation from the first working station to the second working station, it adopts a slow and stable manner to gradually retract the magnetic pop-up component 704. During this process, the magnetic pop-up component 704 does not carry the fastener 10; 2. During the rotation from the second working station to the first working station, the pop-up component 704 carries the fastener 10, and the guide frame 703 can stably limit the magnetic pop-up component 704, and release the magnetic pop-up component 704 at the first working station, and the magnetic pop-up component 704 automatically pops out.

[0062] In one embodiment, the specific installation structure of the barrel housing 701: A sleeve is fixedly arranged at the center of the barrel housing 701. The sleeve is sleeved on the rotating shaft 6 and is fixed by pressing with a nut. A step is designed at a position on the rotating shaft 6 corresponding to the bottom of the sleeve, and a set of nuts is connected to the top end of the rotating shaft 6.

[0063] In one embodiment, the magnetic attraction and ejection assembly 704 includes: a channel body 7041, a mounting block 7042, a strong magnetic block 7045, a push head 7043, a first spring 7044, a linkage frame 7046, and a second spring 7047.

[0064] The channel body 7041 is fixedly connected to the inner side of the barrel housing 701. One end of the channel body 7041 away from the center of the barrel housing 701 is open. The channel body 7041 is along the radial direction of the barrel housing 701. The mounting block 7042 is slidably installed inside the channel body 7041, and a strong magnetic block 7045 is fixedly installed at one end of the mounting block 7042 away from the center of the barrel housing 701. The strong magnetic block 7045 can attract the fastener 10. One end of the mounting block 7042 close to the center of the barrel housing 701 is connected to a push head 7043. The end of the push head 7043 is arc-shaped and abuts against the side surface of the linkage frame 7046. The first end of the first spring 7044 is fixedly connected to the mounting block 7042, and the second end of the first spring 7044 is fixedly connected to one end of the channel body 7041 close to the center of the barrel housing 701. The first spring 7044 is in an extended state, and the elastic force of the first spring 7044 makes the mounting block 7042 have a tendency to slide inward. The top end of the linkage frame 7046 is rotatably connected to the top of the channel body 7041. The linkage frame 7046 is located on the side of the push head 7043 close to the center of the barrel housing 701. The bottom end of the linkage frame 7046 extends downward and is located inside the guide frame 703. The first end of the second spring 7047 is fixedly connected to the bottom of the barrel housing 701, and the second end of the second spring 7047 is fixedly connected to the upper side of the linkage frame 7046 of the barrel housing 701. The second spring 7047 makes the second end and the linkage frame 7046 have an upward rotation tendency. When the linkage frame 7046 rotates upward, it will push the push head 7043 and the mounting block 7042 to slide outward against the elastic force of the first spring 7044. Actually, when in use, the linkage frame 7046 is restricted by the guide frame 703.

[0065] In one embodiment, the guide frame 703 includes an integrally provided semi-circular section 7031, a tapered section 7032, and a transition section 7033. The transition section 7033 is installed between the first end of the semi-circular section 7031 and the first end of the tapered section 7032. The second end of the tapered section 7032 is offset from the second end of the semi-circular section 7031. The distance between the second end of the semi-circular section 7031 and the center of the barrel housing 701 is less than the distance between the second end of the tapered section 7032 and the center of the barrel housing 701.

[0066] During the rotation of the semi-circular section 7031 from the second working station to the first working station, it ensures the stability of the magnetic attraction and ejection component 704. During the rotation of the tapered section 7032 from the first working station to the second working station, it gradually retracts the magnetic attraction and ejection component 704 in a slow and stable manner. The transition section 7033 maintains a smooth connection between the semi-circular section 7031 and the tapered section 7032.

[0067] In one embodiment, the feeding component 8 includes: a first channel 801, a second channel 804, a telescopic member 802, and a push plate assembly 803.

[0068] The first channel 801 is fixedly connected to the base 4, and the first channel 801 is arranged along the radial direction of the feeding tray 7 to guide the fastening member 10 to move to the side position of the feeding tray 7. The second channel 804 is fixedly connected to the base 4, and the second channel 804 is perpendicular to the first channel 801. The end of the second channel 804 communicates with the side of the end of the first channel 801 away from the feeding tray 7. A guiding strip 805 is fixedly connected to the inner side of the second channel 804, and the guiding strip 805 corresponds to the side opening of the fastening member 10, which is used to guide the sliding of the fastening member 10. The telescopic member 802 is fixedly connected to the base 4, and the push plate assembly 803 is slidably connected to the end of the first channel 801 away from the feeding tray 7. The telescopic end of the telescopic member 802 is fixedly connected to the push plate assembly 803.

[0069] The incoming material (fastening member 10) from the end 11 of the vibrating feeder smoothly enters the second channel 804, and under the forward pushing action of the rear material, it passes through the second channel 804 and enters the interior of the first channel 801. The fastening member 10 in the first channel 801 is pushed forward by the push plate assembly 803 driven by the telescopic member 802, and the side of the fastening member 10 close to the feeding tray 7 is attracted by the magnetic attraction and ejection component 704 on the side of the feeding tray 7.

[0070] In one embodiment, an arc-shaped relief opening 902 is provided on the main body block 901 and on the side of the positioning opening to allow the fastening member 10 attracted by the side of the feeding tray 7 to rotate through, so as to ensure that the fastening member 10 can smoothly enter the positioning opening of the main body block 901.

[0071] In one embodiment, a jack is provided on the main body block 901, and an installation strip 906 is inserted into the jack. The cross block member 905 is slidably engaged with the installation strip 906. A guiding portion 9061 is provided at one end of the installation strip 906 to facilitate the replacement / installation of the cross block member 905.

[0075] S2. The operator places the plate member 1 on the base 4, and then starts the ultrasonic welding module 3. The ultrasonic welding module 3 presses down the plate member 1. The plate member 1 contacts the top end of the fastener 10. During the continuous pressing process, the upper part of the side port of the fastener 10 abuts above the cross-block 905, realizing the positioning and fixing of the fastener 10.
