[0031] See Figures 1-10 The diagram schematically illustrates an automatic ultrasonic welding machine for adapter plates according to the present disclosure, comprising a frame 1. The frame 1 is equipped with a first transfer feeding device 2, a second transfer feeding device 3, a first pick-and-place device 11, a second pick-and-place device 12, a first detection component 13, a second detection component 14, a rotary worktable 4, an ultrasonic welding device 15, a flattening and pressure-holding device 5, a feeding device 16, and a transfer receiving device 6. The first pick-and-place device 11, the second pick-and-place device 12, the ultrasonic welding device 15, the flattening and pressure-holding device 5, and the feeding device 16 are sequentially arranged along the circumference of the rotary worktable 4. The first pick-and-place device 11 corresponds and cooperates with the first transfer feeding device 2, the first detection component 13, and the rotary worktable 4, respectively. The second pick-and-place device 12 corresponds and cooperates with the second transfer feeding device 3, the second detection component 14, and the rotary worktable 4, respectively. The feeding device 16 corresponds and cooperates with the transfer receiving device 6 and the rotary worktable 4, respectively. The ultrasonic welding device 15 can be one, two or more, and the ultrasonic welding device 15 is a conventional mechanism in the prior art.

[0032] The rotary worktable 4 is equipped with a welding fixture assembly 7. As the rotary worktable 4 rotates, the welding fixture assembly 7 can be sequentially matched with the first material handling device 11, the second material handling device 12, the ultrasonic welding device 15, the flattening and pressure holding device 5, and the unloading device 16. The number and arrangement of the welding fixture assembly 7 are determined according to the specific situation. Usually, for each station rotated by the rotary worktable 4, the first material handling device 11, the second material handling device 12, the ultrasonic welding device 15, the flattening and pressure holding device 5, and the unloading device 16 each correspond to a welding fixture assembly 7, which is more efficient.

[0033] During use, the first piece of material is stored on the first feeding device, and the second piece of material is stored on the second feeding device. The tray for placing the processed product is placed on the transfer receiving device 6. The rotating worktable 4 rotates, so that the welding fixture assembly 7 on the rotating worktable 4 corresponds and cooperates with the first picking and placing device 11, the second picking and placing device 12, the ultrasonic welding device 15, the flattening and pressure holding device 5, and the unloading device 16 in sequence. The first picking and placing device 11 first picks up the first piece of material from the first transfer feeding device 2, and then the first picking and placing device 11 cooperates with the first detection assembly 13. The first detection assembly 13 detects the position of the first piece of material and whether there are any defects, etc., and then the first picking and placing device 11 then places the first piece of material... The material is precisely placed into the welding fixture assembly 7 of the rotary worktable 4. Similarly, the second material pick-up and drop-off device 12 picks up the second piece of material from the second transfer feeding device 3. The second detection assembly 14 detects the second piece of material and then precisely places the second piece of material on the first piece of material in the welding fixture assembly 7. Then, the ultrasonic welding device 15 welds the second piece of material and the first piece of material in the welding fixture assembly 7. Then, the flattening and pressure holding device 5 flattens and pressures the welded product to ensure the quality of the product. Finally, the unloading device 16 picks up and places the processed product from the welding fixture assembly 7 into the material tray on the transfer receiving device 6 for collection. This operation is continuously repeated, thereby realizing fast, accurate and stable ultrasonic automatic welding of the transfer piece.

[0034] The first transplanting and feeding device 2 includes a first base plate 21, a first lifting component 24, and a first driving mechanism 22. The first driving mechanism 22 drives the first base plate 21 to move horizontally and linearly back and forth. A first fixture plate 23 is arranged sequentially on the first base plate 21 along its direction of movement. There can be one, two, or more first fixture plates 23. A first feeding section 231 for stacking the first piece of material is provided on the first fixture plate 23. There can be one, two, or more first feeding sections 231. The first feeding section 231 can be surrounded by one, two, or more first limiting plates 232. The first limiting plates 232 are installed on the first fixture plate 23. When the first picking and feeding device 11 picks up material, the first lifting component 24 first lifts the first piece of material stacked in the first feeding section 231 upwards, so that the first picking and feeding device 11 can pick up the first piece of material more easily.

[0035] The first drive mechanism 22 can be a cylinder, hydraulic cylinder, electric cylinder, linear module, etc. The first lifting assembly 24 is usually located below the first base plate 21. The first lifting assembly 24 includes a push rod and a drive mechanism such as a cylinder, hydraulic cylinder, electric cylinder, linear module, etc., that drives the push rod to move up and down. The first base plate 21 and the first fixture plate 23 are respectively provided with clearance through holes for the push rod to pass through. The top of the push rod can also be provided with a top block, which can be an elastic block, etc.

[0036] The first base plate 21 is provided with first positioning blocks 211 that cooperate with the first fixture plate 23. The number and arrangement of the first positioning blocks 211 are determined according to specific circumstances. The first fixture plate 23 is provided with a first handle 233 and a first locking element 234. The first locking element 234 can be a rotary plunger, etc. The first fixture plate 23 is first positioned by each of the first positioning blocks 211, and then the first locking element 234 locks the first fixture plate 23 onto the first base plate 21, making it more stable, reliable, and easier to operate. The first handle 233 facilitates the overall removal and placement of the first fixture plate 23. See also Figure 5 As shown, the first fixture plate 23 is provided with first positioning blocks 211 on three sides, and the first positioning blocks 211 on both sides are respectively provided with cover edges. The cover edges can prevent the first fixture plate 23 from moving up and down. The first locking member 234 locks the first fixture plate 23 onto the first base plate 21. By removing the first locking member 234, the first fixture plate 23 can be taken out in the horizontal direction.

[0037] A first sensing switch 26, such as a photoelectric switch or an infrared sensing switch, can also be installed on the first base plate 21. The first sensing switch 26 is used to detect the position of the first piece of material in the first feeding zone 231, so that the first feeding device 11 can pick up the material more accurately. A first linear slide rail 25 or other guiding mechanism that cooperates with the linear movement of the first base plate 21 can also be installed on the frame 1.

[0038] The second transplanting feeding device 3 and the transplanting receiving device 6 are basically the same in structure as the first transplanting feeding device 2, and will not be described in detail here. For example, the transplanting receiving device 6 includes a base plate and a driving mechanism such as a cylinder, oil cylinder, electric cylinder, and linear module that drives the base plate to move horizontally and linearly. A material tray for receiving materials is positioned on the base plate.

[0039] The first pick-and-place device 11 and the second pick-and-place device 12 have basically the same structure. Here, we take the first pick-and-place device 11 as an example. The first pick-and-place device 11 includes a first suction head 111, a second drive mechanism 112, and a first robotic arm 113. The first robotic arm 113 can be a six-axis robotic arm, a swing arm robotic arm, etc. The second drive mechanism 112 can be a cylinder, a hydraulic cylinder, an electric cylinder, a linear module, etc. The first suction head 111 is used to pick up the first piece of material. The first suction head 111 can be a contour suction head, etc. The second drive mechanism 112 drives the first suction head 111 to move up and down. The first robotic arm 113 drives the second drive mechanism 112 and the first suction head 111 to move together, thereby picking up and placing the first piece of material. The unloading device 16 has a similar structure to the first pick-and-place device 11. The first robotic arm 113 can also be replaced with other suitable drive mechanisms such as a cylinder, a hydraulic cylinder, an electric cylinder, a linear module, etc.

[0040] The structures of the first detection component 13 and the second detection component 14 are basically the same; here, we take the first detection component 13 as an example. The first detection component 13 includes a first support 131, on which a first camera 132 and a first material box 133 are mounted. The first camera 132 is used to photograph and inspect the first sheet material picked up by the first material handling device 11, and the first material box 133 is used to collect defective sheets. The first camera 132 can be a CCD camera, etc. The first support 131 can also be equipped with a first light source 134, optical glass, a sliding table, a linear module, etc., which cooperate with the first camera 132. The sliding table, linear module, etc., facilitate adjustment of the position of the first camera 132. The first light source 134 can be a coaxial light source, a ring light source, a strip light source, a backlight source, a surface light source, etc. The first camera 132 can also be replaced by other detection mechanisms such as a line laser detector, a 3D scanner, a three-dimensional scanner, or a three-dimensional intelligent sensor.

[0041] The flattening and pressure-holding device 5 includes a second support 51, on which a pressure-holding head 52 and a third drive mechanism 53 for driving the pressure-holding head 52 to move up and down are mounted. The third drive mechanism 53 can be a cylinder, hydraulic cylinder, electric cylinder, linear module, etc. The pressure-holding head 52 is located above the welding fixture assembly 7. When the welded product rotates to the area below the pressure-holding head 52, the third drive mechanism 53 drives the pressure-holding head 52 to move downward, so that the pressure-holding head 52 presses the product to flatten and hold pressure, eliminating stress deformation caused by welding.

[0042] The welding fixture assembly 7 includes a first fixture base 71, a movable cover plate 72 disposed on the first fixture base 71, and a fourth drive mechanism 73. The first fixture base 71 is located above the rotary table 4. The first fixture base 71 is provided with a first positioning groove 711 for positioning and placing the first piece of material. The movable cover plate 72 is provided with a first positioning through hole 721 for the second piece of material to pass through. The first positioning groove 711 on the first fixture base 71 can be one, two, or more. The fourth drive mechanism 73 can be a cylinder, hydraulic cylinder, electric cylinder, linear module, etc. The fourth drive mechanism 73 can drive the movable cover plate 72 to open and close relative to the first fixture base 71. Before placing the first piece of material, the movable cover plate 72 is open relative to the first fixture seat 71. After the first material handling device 11 places the first piece of material into the first positioning groove 711, the fourth drive mechanism 73 drives the movable cover plate 72 to move, so that the fourth drive mechanism 73 covers the first fixture seat 71. At this time, the first positioning groove 711 is located below the first positioning through hole 721. Then, after the second material handling device 12 places the second piece of material into the first positioning through hole 721, the second piece of material is accurately placed on the first piece of material along the first positioning through hole 721, making the structure more compact and stable.

[0043] The first positioning groove 711 is provided with material guiding limit blocks 713 around its perimeter. The number and arrangement of the material guiding limit blocks 713 are determined according to the specific situation. The material guiding limit blocks 713 can also be provided with material guiding slopes to facilitate the first piece of material to be better placed into the first positioning groove 711. The first positioning through hole 721 can also be provided with material guiding slopes around its perimeter to facilitate the second piece of material to be better entered into the first positioning through hole 721.

[0044] One end of the movable cover plate 72 is provided with a first rotating shaft 722. The first rotating shaft 722 and the movable cover plate 72 can be connected by fasteners such as screws. The first positioning groove 711 is located on one side of the first rotating shaft 722. The first fixture seat 71 is provided with a first support 712 that is hinged to both ends of the first rotating shaft 722. One end of the first rotating shaft 722 can be provided with a flange for limiting. The other end of the first rotating shaft 722 can be locked by an elastic retaining ring or nut. One end of the fourth drive mechanism 73 is hinged to the movable cover plate 72, and the other end of the fourth drive mechanism 73 is hinged to the first fixture seat 71. Supports that are hinged to the fourth drive mechanism 73 can be provided on the movable cover plate 72 and the first fixture seat 71, respectively. During use, the fourth drive mechanism 73 drives the movable cover plate 72 to rotate up and down around the first rotating shaft 722 as the central axis, so that the movable cover plate 72 opens and closes relative to the first fixture seat 71, making the operation more convenient, stable and reliable.

[0045] The frame 1 is equipped with a second lifting assembly 8 that corresponds to and cooperates with the ultrasonic welding device 15 and the flattening and pressure holding device 5 respectively. The second lifting assembly 8 is located below the rotary table 4. The welding fixture assembly 7 also includes a first top plate 74 located below the rotary table 4. The first top plate 74 is fixedly connected to the lower end of the first guide rod 75, and the upper end of the first guide rod 75 is fixedly connected to the first fixture seat 71. The rotary table 4 is equipped with a first guide sleeve 41 that cooperates with the first guide rod 75. A first spring 76 is sleeved on the first guide rod 75. The top of the first spring 76 presses against the rotary table 4, and the bottom of the first spring 76 presses against the first top plate 74. The number and arrangement of the first guide rod 75, the first guide sleeve 41 and the first spring 76 are determined according to the specific situation. When the rotary worktable 4 drives the welding fixture assembly 7 to rotate to the position corresponding to the ultrasonic welding device 15 and the flattening and pressure holding device 5, that is, when the welding fixture assembly 7 moves to the position corresponding to the second lifting assembly 8, the second lifting assembly 8 first lifts the welding fixture assembly 7 upward as a whole, and then welds and holds pressure on the product in the welding fixture assembly 7, which can reduce the load on the rotary worktable 4, etc. The first spring 76 has a buffer protection function, and the first spring 76 can also make the welding fixture assembly 7 automatically reset, which is safer and more reliable.

[0046] The second lifting component 8 typically includes a top plate and a drive mechanism that drives the top plate to move up and down. The drive mechanism can be a pneumatic cylinder, hydraulic cylinder, electric cylinder, linear module, etc.

[0047] The rotary worktable 4 is driven by the fifth drive mechanism 42, which includes a rotary motor, a hollow shaft motor, a hollow rotary table, a rotary cylinder, etc. The center of the rotary worktable 4 is provided with a third support 43, which is connected to the rotation module of the electric slip ring 44. The rotation axis of the rotary worktable 4 and the electric slip ring 44 are the same, which makes it easier to arrange circuits and air passages.

[0048] The lower surface of the rotary table 4 is provided with first contact blocks 45 corresponding one-to-one with the welding fixture assembly 7. The frame 1 is provided with positioning wheel assemblies 17 that can cooperate with the first contact blocks 45. When the welding fixture assembly 7 rotates to the positions corresponding to the first material handling device 11, the second material handling device 12, the ultrasonic welding device 15, the flattening and pressure holding device 5, and the unloading device 16, the positioning wheel assembly 17 cooperates with the first contact blocks 45 for positioning, resulting in higher precision, greater safety, stability, and reliability. The positioning wheel assembly 17 typically includes a bracket, on which a positioning wheel and a spring cooperating with the positioning wheel are provided, allowing the positioning wheel to elastically engage with the first contact block 45. The frame 1 can also be equipped with a sensor switch for detecting the position of the positioning wheel assembly 17, such as a photoelectric switch or an infrared sensor switch. The sensor switch and the positioning wheel assembly 17 can more accurately ensure the rotational position of the positioning wheel assembly 17.

[0049] A protective cover can be installed on the frame 1, and all relevant devices are located within the protective cover. The protective cover can also be equipped with multiple layers of warning lights, safety light curtains, etc., making it safer and more reliable. The bottom of the frame 1 can be equipped with casters with adjusting blocks, which facilitates the overall movement and leveling of the equipment, making operation convenient and improving the flexibility and stability of the equipment.
