Description

Technical Field

[0001] The invention belongs to the technical field of ultrasonic torsion welding, and in particular relates to an assembly line processing type ultrasonic torsion welding device. Background Art

[0002] Ultrasonic welding is a process in which an ultrasonic generator converts a 50 / 60 Hz current into 15, 20, 30 or 40KHz electrical energy. The converted high-frequency electrical energy is converted again into mechanical motion of the same frequency by a transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude-changing rod devices that can change the amplitude. The welding head transmits the received vibration energy to the joint of the workpiece to be welded, and in this area, the vibration energy is converted into heat energy by friction to melt the plastic. Ultrasonic waves can not only be used to weld hard thermoplastics, but also to process fabrics and films.

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Please refer to Figures 1 - 8 , the present invention provides a technical solution: an ultrasonic torsional welding device for pipeline processing, including a base 1, on which there are two horizontal and vertical threaded rods 4 for driving each mold clamping base 5 slidably arranged on the base 1 to move in an L-shaped pipeline. Above the mold clamping base 5 at the L-shaped corner, there is an ultrasonic torsional welder 6 moved by a lifting assembly 2. The lifting assembly 2 is in transmission connection with the two threaded rods 4 through a transmission assembly 3, and is used to drive the horizontal threaded rod 4 to rotate when the ultrasonic torsional welder 6 rises, and drive the vertical threaded rod 4 to rotate when the ultrasonic torsional welder 6 descends.

[0032] In this embodiment, the lifting assembly 2 that controls the ultrasonic torsional welder 6 is in transmission connection with the two horizontal and vertical threaded rods 4 that control the L-shaped pipeline movement of the mold clamping base 5 through the transmission assembly 3. When the ultrasonic torsional welder 6 rises after welding, it drives the mold clamping base 5 to move along the longitudinal groove 112 to move the welded material out of the welding point, for the export of the material; when the ultrasonic torsional welder 6 descends after welding, it drives the receiving part to move along the horizontal groove 111 to move the material to be welded into the welding point, for the import of the material.

[0033] Please refer to Figure 1 , Figure 3 and Figure 4A U-shaped stand 21 is provided on the side of the base 1, and a motor 22 of the lifting assembly 2 is provided on the upper end of the stand 21. A first screw 23 is fixedly installed on the output shaft of the motor 22. A slider 24 is screwed to the first screw 23 to drive the slider 24 to perform a limited lifting movement along the stand 21. An ultrasonic torsional welder 6 is installed on the side of the slider 24.

[0034] In this embodiment, vertical grooves are provided on both sides of the inner wall of the stand 21, and the slider 24 slides along the vertical grooves through the protrusions, so that the motor 22 is started, and the motor 22 drives the first screw 23 to rotate. The rotation of the first screw 23 drives the slider 24 to move up and down along the stand 21, thereby realizing the lifting and lowering of the ultrasonic torsion welding machine 6 and welding the material on the mold base 5 located at the corner of the L-shaped slide groove 11.

[0035] See also Figure 1 , Figures 3 - 8 The upper surface of the base 1 is provided with two horizontal and vertical slide grooves 11 with an inverted "convex" cross section, which are a horizontal groove 111 and a vertical groove 112 respectively. The two slide grooves 11 form an L shape. A threaded rod 4 is rotatably arranged on the bottom side of each slide groove 11. The slide seat 51 of the mold clamping seat 5 is screwed with the threaded rod 4 through a semi-threaded groove 52 arranged on the side, so as to move the mold clamping seat 5 along the slide groove 11. The transmission assembly 3 includes a rotating rod 31 fixed to the bottom of the first screw rod 23, and a limiting sleeve 32 is sleeved on the outer side of the rotating rod 31. The upper and lower ends of the limiting sleeve 32 are respectively fixedly connected with a first output bevel gear 33 and a second output bevel gear 34. A straight rod 35 is arranged on the side of the limiting sleeve 32. The straight rod 35 is connected to the slider 24 through an elastic rope 36, so that the limiting sleeve 32 is driven to rise by the slider 24. A transverse screw 41 in the threaded rod 4 is rotatably disposed inside the transverse groove 111, and the transverse screw 41 is screwed in contact with a transverse screw groove 521 provided on the lateral side of the slide seat 51, so as to move the mold clamping seat 5 along the transverse groove 111. A first pulley 373 is rotatably disposed at one end of the transverse screw 41, and a second input bevel gear 371 is rotatably disposed at the lower side of the second output bevel gear 34, and a second pulley 372 is coaxially disposed on the second input bevel gear 371, and the first pulley 373 and the second pulley 372 are connected through a first belt 374.

[0036] In this embodiment, the second input bevel gear 371 rotates unidirectionally. It only rotates when the first screw rod 23 drives the slider 24 to descend, and does not rotate vice versa. Specifically, the unidirectional rotation is achieved through a built-in one-way bearing. Since the first pulley 373 and the second pulley 372 are not in the same plane, the first belt 374 connecting the two in transmission is in a twisted state. Specifically, when welding is performed, the motor 22 drives the first screw rod 23 to rotate. The first screw rod 23 moves the slider 24 downward along the vertical frame 21. When the sliding seat 51 descends below two-thirds of the height of the vertical frame 21, the tensioning rope 36 becomes slack, and the limiting sleeve 32 descends under its own weight, so that the second output bevel gear 34 meshes with the second input bevel gear 371 below the side. The unidirectional second input bevel gear 371 drives the coaxial second pulley 372 to rotate. The second pulley 372 drives the first pulley 373 to rotate through the first belt 374. The first pulley 373 drives the transverse screw rod 41 to rotate. The transverse screw rod 41 drives the sliding seat 51 located in the transverse groove 111 and screwed thereto to move inward along the transverse groove 111, so as to move each mold clamping seat 5 in the transverse groove 111 along the transverse groove 111, and thus move the material to the corner of the L-shaped chute 11, that is, directly below the ultrasonic torsional welder 6.

[0037] Please refer to Figure 1 、 Figures 3 - 8 As shown in FIGS. 1 and 2, two transverse and longitudinal chutes 11 with an inverted "convex" cross-section are provided on the upper surface of the base 1, namely a transverse groove 111 and a longitudinal groove 112. The two chutes 11 form an L shape. A threaded rod 4 is rotatably provided on the bottom side of each chute 11. The sliding seat 51 of the mold clamping seat 5 is screwed to the threaded rod 4 through a semi-threaded groove 52 provided on the side, for the mold clamping seat 5 to move along the chute 11. The transmission assembly 3 includes a rotating rod 31 fixed to the bottom of the first screw rod 23. A limiting sleeve 32 is sleeved outside the rotating rod 31. The upper and lower ends of the limiting sleeve 32 are respectively fixedly connected with a first output bevel gear 33 and a second output bevel gear 34. A straight rod 35 is provided on the side of the limiting sleeve 32. The straight rod 35 is connected to the slider 24 through a tensioning rope 36, for the limiting sleeve 32 to be driven by the slider 24 to rise. A longitudinal screw rod 42 in the threaded rod 4 is rotatably provided inside the longitudinal groove 112. The longitudinal screw rod 42 is in threaded engagement with a longitudinal threaded groove 522 provided on the longitudinal side of the sliding seat 51, for the mold clamping seat 5 to move along the longitudinal groove 112. The front end of the longitudinal screw rod 42 is a smooth rod 385. A third pulley 383 is provided at the front end of the smooth rod 385. A first input bevel gear 381 is rotatably provided above the side of the first output bevel gear 33. The first input bevel gear 381 is coaxially provided with a fourth pulley 382. The third pulley 383 and the fourth pulley 382 are in transmission connection through a second belt 384.

[0038] In this embodiment, the first input bevel gear 381 rotates in one direction. It only rotates when the first screw rod 23 drives the slider 24 to rise, and does not rotate vice versa. Specifically, the one-way rotation is achieved through a built-in one-way bearing. Specifically, the motor 22 drives the first screw rod 23 to reverse and drive the slider 24 to move upward. When the slider 24 rises to two-thirds of the height of the vertical frame 21, the tensioning rope 36 pulls the limit sleeve 32 to move upward along the rotating rod 31, so that the first output bevel gear 33 meshes with the first input bevel gear 381 above the side. The first input bevel gear 381 drives the coaxial fourth pulley 382 to rotate. The fourth pulley 382 rotates through the second belt 384 and the third pulley 383. The third pulley 383 drives the coaxial optical rod 385 to rotate. The rotation of the optical rod 385 drives the longitudinal screw rod 42 to rotate. The longitudinal screw rod 42 drives the slide seat 51 screwed thereto in the longitudinal groove 112 to move outward along the longitudinal groove 112, so as to move the positions of each slide seat 51 in the longitudinal groove 112 and the mold clamping seat 5 above the slide seat 51. After the ultrasonic torsion welding machine 6 completes welding, it drives the welded material to move outward along the longitudinal groove 112 during the rising process to perform the next operation.

[0039] Please refer to Figure 1 、 Figures 4 - 5 , the mold clamping seat 5 is inserted into the upper surface of the slide seat 51, and the slide seat 51 is set to be rectangular. Semi-threaded grooves 52 are opened on adjacent two side surfaces, and balls are arranged on the bottom surface.

[0040] In this embodiment, the mold clamping seat 5 is detachably installed on the slide seat 51 by inserting the insertion block into the insertion hole of the slide seat 51. On the one hand, it is convenient to observe the direction of the semi-threaded groove 52 on the side of the slide seat 51, fit it into the chute 11, and be screwed with the threaded rod 4 in the chute 11. On the other hand, it is convenient to take the mold clamping seat 5 out of the slide seat 51 to adjust the material on the mold clamping seat 5 and adjust the mold clamping seat 5. Transverse screw grooves 521 and longitudinal screw grooves 522 with semi-circular cross-sections are respectively arranged on two adjacent side surfaces of the slide seat 51. The transverse screw groove 521 is used to be screwed with the transverse screw rod 41 in the transverse groove 111, and the longitudinal screw groove 522 is used to be screwed with the longitudinal screw rod 42 in the longitudinal groove 112. Balls are arranged at the bottom of the slide seat 51, which is convenient for the threaded rod 4 to drive the slide seat 51 to move along the chute 11.

[0041] Working principle and usage process of the present invention: After the present invention is installed, the material is placed on the mold clamping base 5, and then the motor 22 is started. The motor 22 drives the first screw rod 23 to rotate. The first screw rod 23 moves the slider 24 downward along the vertical frame 21. The slider 24 drives the ultrasonic torsional welder 6 installed on its side to descend. When the sliding seat 51 descends below two-thirds of the height of the vertical frame 21, the tensioning rope 36 becomes slack, and the limiting sleeve 32 descends under its own weight, so that the second output bevel gear 34 meshes with the second input bevel gear 371 below the side. The one-way second input bevel gear 371 drives the cross screw rod 41 to rotate through the second belt pulley 372, the first belt 374 and the second belt pulley 372. The cross screw rod 41 drives the sliding seat 51 located in the cross groove 111 and screwed thereto to move inward along the cross groove 111, so as to move the positions of each sliding seat 51 in the cross groove 111 and the mold clamping base 5 above the sliding seat 51, so as to move the material to the corner of the L-shaped chute 11. At this time, the ultrasonic torsional welder 6 descends to a suitable position to process the material on the mold clamping base 5 located at the corner of the L-shaped chute 11.

[0042] When the welding is completed, the motor 22 drives the first screw rod 23 to reverse and drive the slider 24 to move upward. The slider 24 drives the ultrasonic torsional welder 6 to move upward accordingly. When the slider 24 rises to two-thirds of the height of the vertical frame 21, the tensioning rope 36 pulls the limiting sleeve 32 to move upward along the rotating rod 31, so that the first output bevel gear 33 meshes with the first input bevel gear 381 above the side. The first input bevel gear 381 drives the optical rod 385 to rotate through the third belt pulley 383, the second belt 384 and the fourth belt pulley 382. The rotation of the optical rod 385 drives the longitudinal screw rod 42 to rotate. The longitudinal screw rod 42 drives the sliding seat 51 located in the longitudinal groove 112 and screwed thereto to move outward along the longitudinal groove 112, so as to move the positions of each sliding seat 51 in the longitudinal groove 112 and the mold clamping base 5 above the sliding seat 51.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
