Description

Ultrasonic welding equipment

The invention provides a welding device, in particular to an ultrasonic welding device for welding at least two linear metal end faces.

The use of ultrasonic high-frequency vibration energy to produce welding effects is a very common processing process. For example, for industrial wires (or, for example, multi-strand leads/harnesses), at least two wires/multi-strand leads (harnesses), by super The sonic generator achieves that the exposed metal ends are welded together. Among them, there is a design to make sliding smoother and withstand strong deformation stress. Therefore, the lifting and moving module is designed to be closer to the welding work area to achieve the function of short arm and high resistance to torsion, but these designs are not It is necessary to pay more attention to its sliding margin tolerance, and because of the sliding loose fitting margin, the large area and large pressure (ie, multiple wires/multi-stranded leads/harness, or thicker leads/harness conditions) are often used in welding. Under pressure, the gap between the gathering mold and the working horn, as well as the gap between the upper mold backing plate and the working horn, is opened. As a result, it is bound to process and manufacture very precise welding equipment, but it is easy to maintain and repair. Complex, on the contrary, if it is not very precise processing and manufacturing, it is very easy to cause poor welding action due to the aforementioned disadvantages, or cause welded workpieces/finished products (for example, at least two bare ends of multi-strand lead wires are connected to each other and braided ) Poor quality of excessive hair embryos.

Another design is to make the process smooth and simplify the maintenance work. Usually the precision roller slide rail is used as the mobile carrier of the lifting mechanism. However, in order to provide the requirement to withstand great torsion stress, a larger slide rail must be selected. However, in order not to occupy too much space in the welding work area, the slide rail structure must be "substantially far away" from the center welding position of the welding work area of the welding device. As a result, not only the overall volume of the welding device is greatly increased, but also The sliding rail structure with long arm is far away from the welding work area, and its deflection will be very large when welding with large load force, which will cause excessive roughness in the welded product during heavy load work.

The embodiment of the present invention is to provide an ultrasonic welding equipment, which can effectively improve the defects that may be generated by the existing ultrasonic welding machine.

The purpose of the present invention is to provide an ultrasonic welding equipment, which allows the movable gathering structure and the movable welding structure to be fast and laterally limited in the compressed space relative to the object to be welded (for example, at least two bare ends of the multi-strand lead). , And the lifting slide rail module can be a cross roller slide rail, a lifting movement module, a lateral movement module and a cylinder rod assembly groove that controls the lifting movement to be integrated to reduce the volume. It not only optimizes the movable welding structure, but also makes The lifting movement module and the lateral movement module are closest to the welding position of the work center on the ultrasonic working surface to improve the welding accuracy. It can solve the problems of the conventional welding range of the object to be welded, which is disadvantageous to the precise positioning of the operation, easy to shift, and the welding device is too large.

Another object of the present invention is to provide an ultrasonic welding device that can accurately, quickly and concisely apply the position and/or welding pressure on the object to be welded.

The adjustment method in the above-mentioned first stage; the screw 332 of the movable gathering structure 30 rotates relative to the rotating bearing seat 331, so that the screw 332 in rotation corresponds to the blind hole 3332 of the axial nut with the threaded portion 3323, and the axial guidance is generated. The limiting body 33 can exhibit a forward sliding movement parallel to the axis of the screw 332. During the axial advancing movement, the limiting body 333 (including the gathering lateral limiting surface 3331) can be adjusted to be parallel to the axis of the screw 332. The ultrasonic working surface 221 moves forward horizontally, so that the gathering lateral limit surface 3331 can be adjusted to be laterally and vertically confined to the upper side of the ultrasonic working surface 221 from the gathering origin R2 to The lateral position of the gathering end R3 (the X direction in Figure 8). Among them, the definition of the loading welding position is based on the compression space P used to insert the two bare metal ends of the two to-be-welded objects 80, 80' into the compression space P along the insertion direction, and form a mutual end-to-end The ground is stacked on the ultrasonic working surface 221.

The third stage: the assembly body 431 and the welding body 432 of the lateral movement module 43 are first driven by the lateral driving cylinder 452 of the movable welding structure 40 in the sliding groove 422 of the lifting movement body 421 and parallel to the super The horizontal and lateral displacement movement is carried out in the direction of the sonic working surface 221, so that the assembly body 431 and the welding body 432 are driven to appropriately "slip and protrude" out of the chute 422 and press against the gathering lateral limit surface 3331 Up (the X direction in Figure 9; that is, the welding starting point R1 moves out of the chute 422 and is located at the gathering end point R3), the welding working surface 4321 of the bottom surface of the welding body 432 after synchronous displacement is parallel to the ultrasonic working surface 221 above; afterwards, the cylinder rod 4511 is controlled by the lifting cylinder 451 to quickly drive (pull down) the lifting movement body 421 to perform a descending sliding movement (in the Y direction in Figure 9), and at the same time, the welding work surface 4321 Corresponding parallel to the ultrasonic working surface 221 close to each other (as shown in Fig. 9), the instant downward pressure channel generated by the rapid descending sliding movement of the lifting moving body 421 can be used to make the already "slip protruding" out of the chute 422 The welding working surface 4321 can quickly and strongly press down the bare ends of the waiting welding object 80, 80' to face the ultrasonic working surface 221, and the ultrasonic high-frequency vibration of the ultrasonic welding head 22 exerts supersonic waves. The sonic energy is applied to the ultrasonic working surface 221, so that the bare ends of the objects 80, 80' waiting to be welded can be quickly and accurately ultrasonically welded and fixed to each other.

The fourth stage: After the bare ends of the objects 80, 80' waiting to be welded are quickly and accurately connected to each other by ultrasonic welding, the lifting cylinder 451 of the movable welding structure 40 controls the cylinder rod 4511 to drive (upward upwards). Moving) The lifting and moving body 421 performs ascending and sliding movement, so that the assembly body 431 and the welding body 432 of the lateral movement module 43 are first away from the ultrasonic welding head 22 and the ultrasonic working surface 221 and the welded workpiece (ie the original In order to wait for the welding objects 80, 80' to expose the ends), the assembly body 431 and the welding body 432 are driven to “slide and retract” laterally together in the chute 422 (that is, move into the chute 422 from the gathering end R3) And the back is located at the welding starting point R1), synchronously the welding working surface 4321 is moved backward from the gathering end point R3 into the chute 422 and back at the welding starting point R1.
