DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Embodiment 1

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides a technical solution: an ultrasonic welding machine, comprising a workbench 1 and an ultrasonic welding machine 2, the ultrasonic welding machine 2 is fixedly connected to the outer wall of the workbench 1, a feeding assembly 5 is mounted on the inner wall of the workbench 1, and the feeding assembly 5 comprises: an adjusting mechanism 51, the adjusting mechanism 51 is mounted inside the workbench 1, a feeding mechanism 52 is mounted on the inner wall of the workbench 1, and a fixing mechanism 53 is mounted on the outer wall of the feeding mechanism 52;

[0032] The adjusting mechanism 51 includes a handle 511, which is mounted on the surface of the workbench 1. A connecting gear 512 is fixedly connected to the outer wall of one end of the handle 511. A first gear ring 513 is meshed on the surface of the connecting gear 512, and the first gear ring 513 is slidably connected to the inner wall of the workbench 1. A transmission gear 514 is meshed on the surface of the first gear ring 513. A ratchet 515 is fixedly connected to the outer wall of the transmission gear 514. A connecting shaft 516 is rotatably connected to the outer wall of the transmission gear 514. A pawl 517 is rotatably connected to the outer wall, a spring sheet 518 is connected to the outer wall of the connecting shaft 516, and the surface of the spring sheet 518 fits with the surface of the pawl 517, a first cross universal joint 5110 is fixedly connected to the outer wall of one end of the connecting shaft 516, a connecting sleeve 5111 is fixedly connected to the outer wall of one end of the first cross universal joint 5110, a connecting rod 5112 is slidably connected to the inner wall of the connecting sleeve 5111, and a second cross universal joint 5114 is fixedly connected to the outer wall of one end of the connecting rod 5112.

[0033] When in use, when the welding surface of the welding material is an inclined surface, the wave handle 511 rotates counterclockwise to drive the connecting gear 512 to rotate. Through the meshing between the connecting gear 512 and the first gear ring 513, the connecting gear 512 can drive the first gear ring 513 to rotate inside the workbench 1 when rotating. When the first gear ring 513 rotates, it drives the transmission gear 514 to rotate through the meshing with the transmission gear 514. Through the arrangement of the ratchet 515 and the pawl 517, the loading tray 5212 can be fed by rotating clockwise. The transmission gear 514 is driven to rotate on the surface of the first gear ring 513 through the connecting sleeve 5111 and the connecting shaft 516. At this time, the transmission gear 514 drives the ratchet 515 to rotate, so that the ratchet 515 squeezes the pawl 517 to rotate on the surface of the connecting shaft 516 and squeezes the spring sheet 518. Then, the spring sheet 518 is forced to push the pawl 517 to reset, so that the transmission gear 514 will not drive the connecting shaft 516 to rotate. When the first gear ring 513 rotates counterclockwise, the transmission gear 514 drives the ratchet 515 to rotate. The ratchet wheel 515 squeezes the pawl 517 and pushes the connecting shaft 516 to rotate, so that the connecting shaft 516 drives the loading plate 5212 to rotate around the ball cage 5210 through the first cross universal joint 5110, the connecting sleeve 5111, the connecting rod 5112 and the second cross universal joint 5114. When in use, the position of the transmission gear 514 on the surface of the first gear ring 513 and the rotation of the handle 511 can adjust the angle of the loading plate 5212, so that the inclined surface of the welding material can be welded with the ultrasonic welding. The machine 2 remains vertical. Through the arrangement of the first cross universal joint 5110, the connecting sleeve 5111, the connecting rod 5112 and the second cross universal joint 5114, when the tilted loading tray 5212 rotates, the first cross universal joint 5110 and the second cross universal joint 5114 will drive the angles of the connecting sleeve 5111 and the connecting rod 5112 to change as the loading tray 5212 rotates. At the same time, the connecting rod 5112 will perform telescopic movement inside the connecting sleeve 5111, thereby improving the overall usability of the device.

[0034] See also Figure 3 As shown in the figure, a support shaft 519 is rotatably connected to the outer wall of the connecting shaft 516, and one end of the support shaft 519 is slidably connected to the inner wall of the first gear ring 513.

[0035] When in use, the support shaft 519 is slidably engaged with the inner wall of the first gear ring 513, so that the transmission gear 514 can be limited and supported, so that the transmission gear 514 can always mesh with the first gear ring 513, thereby improving the overall usability of the device.

[0036] See also Figure 5 As shown in the figure, a limiting block 5113 is fixedly connected to the outer wall of the connecting rod 5112, and the limiting block 5113 is slidably connected to the connecting sleeve 5111 through the connecting rod 5112.

[0037] When in use, the connecting rod 5112 can be limited by the setting of the limit block 5113, so that the connecting rod 5112 can slide inside the connecting sleeve 5111, and the connecting sleeve 5111 can drive the connecting rod 5112 to rotate synchronously when rotating, thereby improving the overall usability of the device.

[0038] See also Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown in the figure, the feeding mechanism 52 includes a driving motor 521, which is installed inside the workbench 1. A connecting disk 522 is fixedly connected to the outer wall of one end of the driving motor 521, and a clamping block 523 is fixedly connected to the outer wall of the connecting disk 522. A rotating shaft 524 is rotatably connected to the inner wall of the workbench 1, and a turntable 525 is fixedly connected to the outer wall of the rotating shaft 524. A clamping groove 526 is provided on the outer wall of the turntable 525, and a first sliding groove 527 is provided on the outer wall of the top end of the rotating shaft 524.

A ball cage 5210 is rotatably connected to the outer wall of the top end of the rotating shaft 524, and a second sliding groove 5211 is provided on the inner wall of the ball cage 5210. A feeding disk 5212 is fixedly connected to the outer wall of the top end of the ball cage 5210.

[0039] When in use, connect an external power source to start the driving motor 521 to drive the connecting disk 522 to rotate. When the connecting disk 522 rotates, it can push the block 523 to make a circular motion with the connecting disk 522 as the center, so that the block 523 enters the interior of the card slot 526 and pushes the turntable 525 and the rotating shaft 524 to rotate. Through the engagement of the steel ball 528, the rotating shaft 524 can drive the loading disk 5212 to rotate through the ball cage 5210 during rotation, thereby intermittently and continuously loading the welding material, greatly increasing the production efficiency. When the angle of the loading disk 5212 is tilted, the steel ball 528 will slide on the surface of the first slide groove 527 and the second slide groove 5211, so that the rotating shaft 524 can continue to drive the loading disk 5212 to rotate through the steel ball 528, thereby improving the overall usability of the device.

[0040] See also Figure 3 As shown in the figure, the top of the rotating shaft 524 is circular, and a plurality of first slide grooves 527 are provided on the circular top of the rotating shaft 524 , and a retaining frame 509 is slidably connected to the outer wall of the steel ball 528 .

[0041] When in use, the retaining frame 509 can ensure that when the loading tray 5212 rotates, the multiple groups of steel balls 528 can be maintained on the same horizontal line, thereby improving the overall usability of the device.

[0042] See also Figure 2As shown in the figure, a cylinder 3 is fixedly connected to the inner wall of the workbench 1, and a rubber pad 4 is fixedly connected to the outer wall of one end of the cylinder 3.

[0043] During use, when the ultrasonic welding machine 2 is welding the welding material, the cylinder 3 pushes the rubber pad 4 to move toward the upper material tray 5212, so that the rubber pad 4 squeezes the surface of the upper material tray 5212 and deforms. The force exerted by the cylinder 3 on the rubber pad 4 on the surface of the upper material tray 5212 can support the upper material tray 5212, so that the upper material tray 5212 can remain stable when the ultrasonic welding machine 2 is working, thereby improving the overall usability of the device.

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown in the figure, the fixing mechanism 53 includes a hand wheel 531, which is mounted on the surface of the feeding mechanism 52. A second gear ring 532 is fixedly connected to the outer wall of one end of the hand wheel 531, and a bevel gear 533 is meshed on the outer wall of the second gear ring 532. A threaded rod 534 is fixedly connected to the outer wall of the bevel gear 533. A fixed platform 535 is threadedly connected to the outer wall of the threaded rod 534. A baffle 536 is fixedly connected to the outer wall of the fixed platform 535. A rotating block 537 is rotatably connected to the inner wall of the fixed platform 535. A driving block 538 is rotatably connected to the outer wall of the rotating block 537. A spring 539 is fixedly connected to the outer wall of one end of the driving block 538. One end of the spring 539 A connecting block 5310 is fixedly connected to the outer wall of one end of the connecting block 5310, a push plate 5311 is fixedly connected to the outer wall of one end of the connecting block 5310, a sliding block 5312 is fixedly connected to the outer wall of the pushing plate 5311, an oil bin 5313 is provided inside the pushing plate 5311, a connecting groove 5314 is provided inside the pushing plate 5311, a return spring 5315 is fixedly connected to the inner wall of the connecting groove 5314, a telescopic rod 5316 is fixedly connected to the outer wall of one end of the return spring 5315, a through hole 5317 is provided between the connecting groove 5314 and the oil bin 5313, a limiting groove 5318 is provided on the outer wall of the fixing platform 535, and the limiting groove 5318 is slidably connected to the sliding block 5312.

[0045] When in use, first place the welding material on the surface of the fixed platform 535, then pull the rotating block 537 upward to drive the driving block 538 to pull the push plate 5311 to slide on the surface of the fixed platform 535 through the spring 539 and the connecting block 5310, and at this time, the slider 5312 slides inside the limiting groove 5318, thereby ensuring the balance of the push plate 5311, thereby pushing the push plate 5311 to move toward the baffle 536, and the telescopic rod 5316 on the surface of the push plate 5311 and the baffle 536 squeezes the two ends of the welding material. After being squeezed, the telescopic rod 5316 on the surface of the welding material will push the telescopic rod 5316 to slide inside the push plate 5311 and the baffle 536, and squeeze the hydraulic oil inside the connecting groove 5314, and the hydraulic oil will pass through the through hole after being squeezed. 5317 enters the interior of the oil bin 5313 and pushes the telescopic rod 5316 that is not in contact with the welding material to move outward, thereby squeezing the surface of the welding material and fixing the welding material of irregular shape. When the welding material is not located directly below the ultrasonic welding machine 2, the hand wheel 531 is turned to drive the second gear ring 532 to rotate. Through the engagement of the second gear ring 532 with the bevel gear 533, the second gear ring 532 can drive the bevel gear 533 and the threaded rod 534 to rotate when it rotates. Through the rotation of the threaded rod 534, the rotational motion of the fixed platform 535 and the threaded rod 534 can be converted into a linear motion of the fixed platform 535 on the surface of the loading tray 5212, thereby moving the welding material to directly below the ultrasonic welding machine 2, thereby improving the overall ease of use of the device.

[0046] See also Figure 8 As shown in the figure, the surfaces of the baffle plate 536 and the push plate 5311 are both provided with a telescopic rod 5316, and the telescopic rod 5316 forms a telescopic structure through a return spring 5315 and a connecting groove 5314.

[0047] When in use, when the telescopic rod 5316 is not subjected to force, the return spring 5315 can push the telescopic rod 5316 to return to its original position.
