Technical Field

[0001] The utility model relates to the technical field of ultrasonic welding machines, in particular to a guided and positioned power board ultrasonic welding machine. Background Art

[0002] The power board is an important electronic component that is responsible for converting, distributing and stabilizing the input power, providing stable and appropriate power to various components of the equipment.

[0003] Existing ultrasonic welding machines are unable to position the power board when welding it. Most of them have a notch at the bottom of the welding head so that the power board will not move inside the notch. However, the models and sizes of power boards vary, so it is necessary to change the size of the notch at the bottom, which is extremely inconvenient. At the same time, this equipment uses a positioning wheel, but the positioning wheel will wear out after long-term use and needs to be replaced. The traditional positioning wheel has a single fixing method and is difficult to disassemble. Utility Model Content

[0007] As a preferred technical solution of the present invention, the torsion spring is located between the rotating L-block and the fixed rod, and both ends of the torsion spring are overlapped with the fixed rod and the rotating L-block respectively.

[0008] As a preferred technical solution of the present invention, a circular groove is provided at the bottom of the insertion block, and the diameter of the circular groove is the same as the diameter of the top of the locking pin.

[0009] As a preferred technical solution of the present invention, there are two positioning wheel assemblies, and the two positioning wheel assemblies are symmetrically arranged inside the fixing bar.

[0013] 2. The guided positioning power board ultrasonic welding machine presses down the extension block on the outer wall of the lock pin, thereby moving the lock pin downward, so that the lock pin disengages from the circular groove at the bottom of the insertion block, and then the spring contracts. At this time, the mounting block is pulled outward, so that the mounting block drives the insertion block to move out from the inside of the rotating L block. At this time, the mounting block and the positioning rotating wheel are replaced. BRIEF DESCRIPTION OF THE DRAWINGS

In the above structure, a strip groove is provided on the top of the base 1, and the number of the strip grooves is two. The two strip grooves are located on both sides of the fixed bar 6, and the fixed bar 6 and the pulling plate 5 are connected by the strip groove.

[0023] In a preferred embodiment, the positioning wheel assembly 7 includes an adjustment seat 701, a fixed rod 702 is fixedly installed at the bottom of the adjustment seat 701, and a rotating L block 703 is rotatably sleeved on the outer wall of the fixed rod 702. The inner wall of the rotating L block 703 is respectively provided with a torsion spring 704 and a spring 709, and the inner wall of the rotating L block 703 is slidably connected with an insertion block 706. The outer wall of the insertion block 706 is fixedly installed with a mounting block 705. The bottom of the mounting block 705 is rotatably connected to a positioning rotating wheel 707, and the inner wall of the rotating L block 703 is slidably connected to the locking pin 708. In the above structure, when one of the positioning rotating wheels 707 overlaps the outer wall of the power board, the positioning rotating wheel 707 is pushed by the driving force, thereby pushing the mounting block 705, and the rotating L block 703 is driven to rotate by the mounting block 705, so that the positioning rotating wheel 707 on the other side moves toward the outer wall of the other side of the power board, thereby enabling the positioning wheel assembly 7 to position a corner of the power board.

[0024] In a preferred embodiment, the torsion spring 704 is located between the rotating L block 703 and the fixed rod 702, and the two ends of the torsion spring 704 are respectively overlapped with the fixed rod 702 and the rotating L block 703.

When the rotational force of the rotating L block 703 disappears, the torsion spring 704 drives the rotating L block 703 to reset the structure.

[0025] In a preferred embodiment, a circular groove is provided at the bottom of the insertion block 706, and the diameter of the circular groove is the same as the top diameter of the locking pin 708. In the above structure, the insertion block 706 is fixed by inserting the locking pin 708 into the insertion block 706.

[0026] In a preferred embodiment, there are two positioning wheel assemblies 7 , and the two positioning wheel assemblies 7 are symmetrically arranged inside the fixing bar 6 . In the above structure, one side of the power board can be positioned by the two positioning wheel assemblies 7 .

[0027] In a preferred embodiment, the number of pulling plates 5, fixing bars 6 and connecting rods 10 is two, and the two pulling plates 5, fixing bars 6 and connecting rods 10 are symmetrically arranged on both sides of the inner wall of the base 1, and the two connecting rods 10 are rotatably connected to the two pulling plates 5 at one end away from the rotating plate 9. In the above structure, by starting the cylinder 4, the cylinder 4 drives the pulling plate 5 to move, and the movement of the pulling plate 5 drives the fixing bar 6 and one end of the connecting rod 10 to move, and the other end of the connecting rod 10 drives one end of the rotating plate 9 to move, and the rotating plate 9 rotates on the outer wall of the fixed seat 8. At this time, the rotation of the rotating plate 9 drives one end of the connecting rod 10 on the other side to move, and then pulls the pulling plate 5 on the other side toward the middle, so that the pulling plates 5 and the fixing bars 6 on both sides move toward the middle at the same time, and the two sides of the power board are positioned by the positioning wheel assembly 7 inside the two fixing bars 6.

[0028] Working principle: when using this device, the power board is placed on the top of the base 1, and the cylinder 4 is started at this time, so that the cylinder 4 drives the pulling plate 5 to move, and the movement of the pulling plate 5 drives the fixed bar 6 and one end of the connecting rod 10 to move, and the other end of the connecting rod 10 drives one end of the rotating piece 9 to move, so that the rotating piece 9 rotates on the outer wall of the fixed seat 8. At this time, the rotation of the rotating piece 9 drives one end of the connecting rod 10 on the other side to move, and then pulls the pulling plate 5 on the other side to move toward the middle, so that the pulling plates 5 and the fixing bars 6 on both sides move toward the middle at the same time, and the two sides of the power board are positioned by the positioning wheel assembly 7 inside the two fixing bars 6, so that the power board is located at the bottom of the ultrasonic welding device 3. At this time, the ultrasonic welding device 3 is started, and the ultrasonic welding device 3 is used to When the power board is welding, and the positioning rotating wheel 707 needs to be replaced, the extension block on the outer wall of the locking pin 708 is pressed downward, so that the locking pin 708 moves downward, so that the locking pin 708 disengages from the circular groove at the bottom of the insertion block 706, thereby causing the spring 709 to contract. At this time, the mounting block 705 is pulled outward, so that the mounting block 705 drives the insertion block 706 to move out from the inside of the rotating L block 703. At this time, the mounting block 705 and the positioning rotating wheel 707 are replaced. When the distance between the positioning wheel assembly 7 needs to be adjusted, the rotating disk 12 is rotated, so that the rotating disk 12 drives the double-headed screw 11 to rotate. The double-headed screw 11 drives the two adjustment seats 701 to move toward the middle through the thread on the outer wall, thereby driving the two positioning wheel assemblies 7 to move toward the middle for adjustment.
