Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding disc feeding, in particular to a disc feeding structure of a connecting piece copper ultrasonic welding machine. Background Technique
[0002] During product production, welding is one of the important steps. Ultrasonic welding is also a thermal welding method, but the required heat is obtained by ultrasonic excitation of plastic to generate high-frequency mechanical vibration. When ultrasonic waves are directed to the surface of the plastic to be welded, the plastic particles are excited by the ultrasonic waves to make rapid vibrations and thus generate mechanical work. As it is then converted into heat, the temperature of the thermoplastic plastic will rise until it melts. The plastic at the non-welded surface will not have its temperature rise. The form of mechanical work is the continuous alternating compression and decompression of the plastic particles caused by vibration and the frictional vibration between the welded surfaces caused by vibration. The frequency of vibration is equal to the frequency of the ultrasonic waves, and its range is 20 - 40 kHz. Laser welding is one of the important aspects of the application of laser material processing technology. Automatic ultrasonic welding machines are used for the ultrasonic welding and shaping integrated forming process of connecting piece copper / aluminum foils.
[0003] The whole machine includes a multi-position synchronous handling module for material sheets, a disc transfer mechanism, secondary positioning of material sheets, an artificial disc feeding position, an ultrasonic welding module, an eight-position disc transfer module, a welding pressing device, a post-welding flattening module, and a blanking storage material conveying line. When welding copper sheets on the whole machine, the artificial disc feeding position adopts a six-station disc feeding structure. The following problems exist during the use of this structure: The six-station disc feeding structure adopts a cartridge-type positioning method. Although it can adaptively clamp copper sheets of different sizes, due to the limitations of the cartridge type, the stability of the copper sheets during clamping is not high. Moreover, during manual feeding by the operator, the position of the cartridge needs to be manually controlled to position the copper sheets, resulting in low efficiency during disc feeding. In view of this, we propose a disc feeding structure of a connecting piece copper ultrasonic welding machine. Content of the Utility Model
[0004] In view of the deficiencies of the prior art, the utility model provides a disc feeding structure of a connecting piece copper ultrasonic welding machine, which solves the problems raised in the above background technique. To achieve the above purposes, the utility model is realized through the following technical solutions: A disc feeding structure of a connecting piece copper ultrasonic welding machine includes a disc base. The disc base is connected with a feeding disc through a rotating shaft, and the rotating shaft is externally connected to a power component to drive the feeding disc to rotate on the disc base. An air pressure base is fixedly connected to the feeding disc. An automatic cartridge device is arranged inside the air pressure base. A clamping plate is arranged on the automatic cartridge device, and a positioning device for secondary positioning of the clamping plate is arranged inside the air pressure base.
[0005] Preferably, the automatic magazine device includes a pressed ring seat, a total air pressure plate, and a sub-air pressure plate. The pressed ring seat is fixedly connected to a fixed shaft through a connecting rod, and the fixed shaft is fixedly connected to the disc base. The surfaces of the total air pressure plate and the sub-air pressure plate are respectively slidably connected to the inner wall of the air pressure base. A cue stick is fixedly connected to the total air pressure plate, and the sub-air pressure plate is elastically connected to a connecting plate through a spring.
[0006] Preferably, a sealing cavity is provided inside the air pressure base between the total air pressure plate and the sub-air pressure plate.
[0007] Preferably, one side of the total air pressure plate away from the sealing cavity is elastically connected to the inside of the air pressure base through a spring. The surfaces of the cue stick and the connecting plate are respectively slidably connected to the inner wall of the air pressure base, and the top of the connecting plate is fixedly connected to a clamping plate.
[0008] Preferably, the fixed shaft is rotatably connected to a rotating shaft. The pressed ring seat is respectively provided with a clamping surface and a positioning surface, and the surface of the cue stick contacts the surface of the clamping surface.
[0009] Preferably, the positioning device includes a toothed plate. The surface of the toothed plate is elastically connected to the inside of the air pressure base through a spring, and one side of the toothed plate is fixedly connected to a passive ring through a connecting shaft.
[0010] Preferably, the surface of the toothed plate is slidably connected to the inner wall of the air pressure base, the surface of the connecting shaft is slidably connected to the inner wall of the air pressure base, and the surface of the passive ring contacts the surface of the positioning surface.
[0011] Preferably, the positioning device further includes teeth fixedly connected to the connecting plate, and the teeth are used for engaging and positioning with the toothed plate.
[0012] As can be seen from the above technical solutions, the disc loading structure of a connecting piece copper ultrasonic welding machine provided by the embodiments of this specification has at least the following beneficial effects:
[0013] (1). By setting the automatic magazine device, the present invention utilizes the rotation of the loading disc to drive the two clamping plates to perform automatic clamping and separation, improving the loading efficiency of the operator for the copper sheet. After the elastic clamping of the clamping plates, the positioning device is used to secondarily fix the clamping plates, thereby improving the effect of the clamping plates for clamping and loading copper sheets of different sizes.
[0014] (2) The utility model squeezes and positions the cue within a certain range through the pressed ring seat, thereby achieving the effect of automatic clamping and separation of the clamping plates. During the rotation of the pneumatic base, the squeezing of the cue on the pressed ring seat drives the movement of the total pneumatic plate. The movement of the total pneumatic plate generates air pressure to drive the sliding of the sub-pneumatic plate. The sub-pneumatic plate drives the upper clamping plate on the connecting plate to move through a spring. At this time, the two clamping plates move relatively closer. During the approaching process, elastic clamping of the copper sheet inside the two clamping plates is achieved. At the same time, affected by the spring on the connecting plate, the clamping plates can perform self-adaptive clamping work on the copper sheet, so that the clamping plates can perform automatic clamping work on copper sheets of different sizes.
[0015] (3) The utility model drives the passive ring to gradually squeeze the positioning surface by rotating the pneumatic base. After being stressed and squeezed, the passive ring drives the toothed plate to move towards the connecting plate through the connecting shaft. After moving, the toothed plate will engage and position the teeth, thereby achieving the effect of rigidly positioning the upper clamping plate on the connecting plate by using the toothed plate. After the clamping plates perform automatic elastic self-adaptive clamping work, the clamping plates are fixed for the second time, thereby improving the effect of clamping and loading copper sheets of different sizes by the clamping plates.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0024] Embodiment 1
[0025] Please refer to Figure 1 - Figure 5 As shown in the figure, a disk loading structure of a connecting piece copper ultrasonic welding machine includes a disk base 1. The disk base 1 is connected to a loading disk 3 through a rotating shaft 2. The rotating shaft 2 is externally connected to a power component to drive the loading disk 3 to rotate on the disk base 1. A plurality of circularly arrayed air pressure bases 4 are fixedly connected to the loading disk 3. An automatic magazine device 5 is arranged inside the air pressure base 4. A clamping plate 6 is arranged on the automatic magazine device 5. A positioning device 7 for secondary positioning of the clamping plate 6 is arranged inside the air pressure base 4.
[0026] In this embodiment, the automatic magazine device 5 includes a pressed ring seat 51, a total air pressure plate 52, and a sub-air pressure plate 53. The pressed ring seat 51 is fixedly connected to a fixed shaft 54 through a connecting rod. The fixed shaft 54 is fixedly connected to the disk base 1. The surfaces of the total air pressure plate 52 and the sub-air pressure plate 53 are respectively slidably connected to the inner wall of the air pressure base 4. A ball rod 55 is fixedly connected to the total air pressure plate 52. The sub-air pressure plate 53 is elastically connected to a connecting plate 56 through a spring. The surfaces of the ball rod 55 and the connecting plate 56 are respectively slidably connected to the inner wall of the air pressure base 4. The top of the connecting plate 56 is fixedly connected to the clamping plate 6. During the rotation of the air pressure base 4, the ball rod 55 is squeezed on the pressed ring seat 51 to drive the total air pressure plate 52 to move. The movement of the total air pressure plate 52 generates air pressure to drive the sub-air pressure plate 53 to slide. The sub-air pressure plate 53 drives the clamping plate 6 on the connecting plate 56 to move through the spring. At this time, the two clamping plates 6 move relatively closer, and during the approaching process, the copper sheets inside the two clamping plates 6 are elastically clamped. At the same time, affected by the spring on the connecting plate 56, the clamping plate 6 can perform self-adaptive clamping work on the copper sheets, so that the clamping plate 6 can perform automatic clamping work on copper sheets of different sizes. A sealing cavity 57 is opened between the total air pressure plate 52 and the sub-air pressure plate 53 inside the air pressure base 4. The side of the total air pressure plate 52 away from the sealing cavity 57 is elastically connected to the inside of the air pressure base 4 through a spring. By setting the automatic magazine device 5, the ball rod 55 is subjected to range squeezing and positioning by the pressed ring seat 51, so as to achieve the effect of automatic clamping and separation of the clamping plate 6, and improve the loading efficiency of the operator for the copper sheets.
[0027] Furthermore, the fixed shaft 54 is rotatably connected to the rotating shaft 2. The pressed ring seat 51 is respectively provided with a clamping surface 58 and a positioning surface 59. The surface of the cue 55 contacts the surface of the clamping surface 58. The area of the pneumatic base 4 corresponding to the notch of the pressed ring seat 51 is set as the loading area. In this area, the cue 55 and the passive ring 73 will not be restricted by extrusion. At this time, the total pressure plate 52 and the toothed plate 71 are in the initial position, and the two symmetrically distributed clamping plates 6 on the pneumatic base 4 are at the farthest distance. At this time, it is convenient for the operator to place the copper sheet between the two clamping plates 6.
[0028] Embodiment 2
[0029] Please refer to Figures 3 - 5 As shown, the positioning device 7 includes a toothed plate 71 and a tooth 74 fixedly connected to the connecting plate 56. The tooth 74 is used for clamping and positioning with the toothed plate 71. The surface of the toothed plate 71 is elastically connected to the inside of the pneumatic base 4 through a spring, and the surface of the toothed plate 71 is slidably connected to the inner wall of the pneumatic base 4. One side of the toothed plate 71 is fixedly connected with a passive ring 73 through a connecting shaft 72. The surface of the connecting shaft 72 is slidably connected to the inner wall of the pneumatic base 4. The surface of the passive ring 73 contacts the surface of the positioning surface 59. After the clamping plate 6 performs elastic clamping, continue to rotate the pneumatic base 4 to drive the passive ring 73 to gradually press the positioning surface 59. After the passive ring 73 is stressed and squeezed, it drives the toothed plate 71 to move towards the connecting plate 56 through the connecting shaft 72. After moving, the toothed plate 71 will clamp and position the tooth 74, so as to use the toothed plate 71 to achieve the effect of rigidly positioning the clamping plate 6 on the connecting plate 56. After the clamping plate 6 performs automatic elastic adaptive clamping work, the clamping plate 6 is fixed for the second time, so as to improve the effect of the clamping plate 6 for clamping and loading copper sheets of different sizes.
[0030] When the disk loading structure of the copper ultrasonic welding machine for connecting pieces of the present utility model is in use, the power assembly drives the loading disk 3 on the rotating shaft 2 and the multiple pneumatic bases 4 distributed in a circular array to rotate for loading. During loading, the operator places the copper sheet on the clamping plate 6, and sets the area of the pneumatic base 4 corresponding to the notch of the pressure ring seat 51 as the loading area. In this area, the ball rod 55 and the passive ring 73 will not be restricted by extrusion. At this time, the total pressure plate 52 and the toothed plate 71 are in the initial position, and the two symmetrically distributed clamping plates 6 on the pneumatic base 4 are at the farthest distance. At this time, it is convenient for the operator to place the copper sheet between the two clamping plates 6. After placement, the power assembly drives the rotating shaft 2 to drive the loading disk 3 to rotate as a whole. During rotation, the pneumatic base 4 gradually rotates to the clamping surface 58. During the rotation of the ball rod 55 along with the pneumatic base 4, it will contact the surface of the clamping surface 58 and be guided and extruded by its upper inclined surface. The ball rod 55 will be pressed to move linearly towards the pneumatic base 4. During the movement, the ball rod 55 squeezes the constant gas in the sealing cavity 57 through the total pressure plate 52, and the air pressure drives the sub-pressure plate 53 to slide in the sealing cavity 57. During the sliding, the sub-pressure plate 53 drives the clamping plate 6 on the connecting plate 56 to move through the spring. The two clamping plates 6 perform a relative approaching movement at this time, and during the approaching, elastic clamping of the copper sheet inside the two clamping plates 6 is realized. At the same time, affected by the spring on the connecting plate 56, the clamping plate 6 can perform self-adaptive clamping work on the copper sheet, so that the clamping plate 6 performs automatic clamping work on copper sheets of different sizes. By setting the automatic spring clip device 5, the ball rod 55 is positioned by using the limited area of the clamping surface 58, so as to realize the effect of automatic clamping and separation of the clamping plate 6, and improve the loading efficiency of the operator for the copper sheet. At the same time, after the clamping plate 6 performs elastic clamping, continue to rotate the pneumatic base 4 to drive the passive ring 73 to gradually squeeze the positioning surface 59. After being stressed and squeezed, the passive ring 73 drives the toothed plate 71 to move towards the connecting plate 56 through the coupling shaft 72. After moving, the toothed plate 71 will perform clamping and positioning on the tooth 74, so as to realize the effect of rigid positioning of the clamping plate 6 on the connecting plate 56 by using the toothed plate 71. After the clamping plate 6 performs automatic elastic self-adaptive clamping work, the clamping plate 6 is fixed for the second time, so as to improve the effect of clamping and loading copper sheets of different sizes by the clamping plate 6.
