Description

Technical Field

[0001] This invention belongs to the field of terminal welding technology, and specifically relates to an ultrasonic welding and assembly machine. Background Technology

[0002] The terminal welding process generally involves the following steps: 1. Positioning and placing the plastic push block; 2. Positioning and placing the terminal; 3. Placing the insulating paper; 4. Placing the arc extinguishing plate; 5. Ultrasonic heat fusion. These steps originally required two sets of equipment (including insulating paper punching) and two workers. The components require numerous placement actions, and since the insulating paper and arc extinguishing plate are smaller than the terminal forming area, manual placement with tweezers is necessary. The assembly time after heat fusion is long and inefficient. Furthermore, when moving to the next workstation, parts may become loose or assembly may be reversed, which is detrimental to the terminal welding process. Summary of the Invention

[0054] Furthermore, the feeding vibratory feeder, feeding channel, and feeding device 303 of the present invention are all devices in the prior art, and will not be described in detail here.

[0055] refer to Figures 1-6 As shown, driver 2 is a stepper motor.

[0056] When this product is in operation, the plastic pusher block first enters the feeding channel 102 through the adjustment of the feeding vibratory feeder 101. After passing through the feeding channel 102, it is pushed towards the clamping point, which is close to the gripping mechanism 1. At this time, the driver 2 drives the rotating workstation 3 to rotate, which is driven by a stepper motor to achieve precise rotation. The terminal fixing fixture on the rotating workstation 3 reaches the corresponding assembly workstation position, that is, the pusher block positioning station 100. At this time, the longitudinal cylinder 51 of the gripping mechanism 1 drives the mounting bracket 52 and the lifting cylinder 53 to extend. Then, the lifting cylinder 53 drives its lower pneumatic gripper to move down. After reaching the position of the plastic pusher block, the pneumatic gripper 1 pneumatically closes and grasps the plastic pusher block. Then, the lifting cylinder 53 drives its lower pneumatic gripper 1 to move up. The longitudinal cylinder 51 then drives the mounting bracket 52 and the lifting cylinder 53 to move up. 3. The plastic pusher is retracted, so that it reaches the corresponding terminal fixing fixture on the rotary workstation 3. Then, the lifting cylinder 53 drives the pneumatic gripper at its lower end to move down and open and close, so that the plastic pusher is placed on the corresponding terminal fixing fixture. With this working step, the set gripping mechanism can continuously grip the plastic pusher and place it on the corresponding terminal fixing fixture. After the plastic pusher is placed on the corresponding terminal fixing fixture, the driver 2 drives the rotary workstation 3 to rotate, so that the terminal fixing fixture with the plastic pusher is moved to the position of the photoelectric detection component 103. After the photoelectric detector of the set photoelectric detection component 103 senses that the plastic pusher is placed on the terminal fixing fixture, the rotary workstation 3 continues to rotate, moving the terminal fixing fixture with the plastic pusher to the next workstation, namely the terminal positioning station 200.

[0057] When the terminal fixing fixture with the plastic pusher block moves to the terminal positioning station 200, the terminal enters the feeding channel 202 through the adjustment of the feeding vibratory plate 201. The terminal is pushed to the clamping point through the feeding channel 202, which is close to the gripping mechanism 2. The working mode of the gripping mechanism 2 is the same as that of the gripping mechanism 1. That is, after the pneumatic gripper 2 of the gripping mechanism 2 grips the terminal onto the terminal fixing fixture with the plastic pusher block, the terminal is placed on the plastic pusher block. Then the rotating work station plate 3 continues to rotate, so that the terminal fixing fixture with the terminal is moved to the position of the photoelectric detection component 203. After the photoelectric detector of the photoelectric detection component 203 senses that the terminal is placed on the terminal fixing fixture, the rotating work station plate 3 continues to rotate, moving the terminal fixing fixture with the terminal to the next work station, namely the insulating paper positioning station 300.

[0058] When the terminal fixing fixture with the terminal is placed moves to the insulating paper positioning station 300, the insulating paper strip on the insulating paper roll placement rack 301 is transferred to the insulating paper strip support plate 302, and is moved and cut by the feeding device 303. Then, the suction nozzle of the suction punch of the gripping mechanism 3 can pick up the insulating paper and move it to the terminal fixing fixture with the terminal. Then, the rotating work station disk 3 continues to rotate, moving the terminal fixing fixture with the insulating paper to the position of the re-pressing component 304. The pressure block of the re-pressing component 304 can re-press the insulating paper on the terminal fixing fixture to ensure the insulating paper is positioned and installed on the terminal. The rotating work station disk 3 continues to rotate, moving the terminal fixing fixture with the insulating paper to the next work station, namely the arc extinguishing plate positioning station 400.

[0059] When the terminal fixing fixture with insulating paper is moved to the arc extinguishing plate positioning station 400, the arc extinguishing plate enters the feeding channel 402 through the adjustment of the feeding vibrating plate 3 401. After passing through the feeding channel 3 402, it is pushed to the arc extinguishing plate clamping point, that is, the position close to the gripping mechanism 4. The pneumatic gripper 3 of the gripping mechanism 4 grips the arc extinguishing plate onto the terminal fixing fixture with insulating paper, that is, the arc extinguishing plate is placed on the insulating paper. Then the rotating work station 3 continues to rotate, moving the terminal fixing fixture with arc extinguishing plate to the position of the repressing component 2 403. The pressure block 2 of the repressing component 2 403 can repress the arc extinguishing plate on the terminal fixing fixture to ensure that the arc extinguishing plate is correctly placed. Then, the rotating work station 3 continues to rotate, moving the terminal fixing fixture with arc extinguishing plate to the next work station, that is, the hot melt positioning station 500.

[0060] After the terminal fixing fixture with the arc extinguishing plate is moved to the hot melt positioning station 500, the lifting drive cylinder 502 drives the ultrasonic generator 504 to move, so that the ultrasonic welding head of the ultrasonic generator 504 reaches the product welding position and welds the plastic push block. The ultrasonic welding head heats up and melts the plastic push block welding column, thereby fixing the components on the product. Then the rotating workstation 3 continues to rotate, moving the terminal fixing fixture with the welded terminal to the position of the photoelectric detection component 3 505. The photoelectric detector of the photoelectric detection component 3 505 is used to sense whether the terminal product is still on the corresponding terminal fixing fixture. Then, the rotating workstation 3 continues to rotate, moving the terminal fixing fixture with the welded terminal to the next workstation, namely the product receiving station 600.

[0061] When the product arrives at the product receiving station 600, the pneumatic gripper four of the gripping mechanism five can grab the welded terminal product and move it to the product receiving box 601. The process is completed. The welding of the terminal product can be completed when the rotating workstation disk 3 rotates once, which is more efficient and reduces the manual transportation and assembly links.

[0062] The ultrasonic welding machine for terminals described in this invention is an integrated automatic device that combines insulating paper cutting / component assembly and ultrasonic welding into one machine, reducing manual transportation and assembly steps. It utilizes a mature feeding mechanism and a disc-type worktable to reduce the space required for the automatic machine. The machine uses pneumatic grippers to perform clamping and feeding actions multiple times, resulting in a simple structure that is easy to adjust. Each workstation is equipped with photoelectric induction detection or re-pressure to ensure accurate component placement, improve yield, and reduce manpower to one person for operation. This increases product output efficiency and quality, which is beneficial for terminal welding production.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
