The first embodiment is as follows:
referring to fig. 1, 3 to 14, an embodiment of an ultrasonic welding bottom die device 100 according to the present invention is disclosed. The ultrasonic welding bottom die device 100(100a) disclosed in various embodiments of the present application is directed to ultrasonic welding performed after a water filter (or filter paper) is placed on an empty cup 80 in a hole 2-1 formed at an edge of a rotating disc 2 and uniformly or non-uniformly in a ring shape by an ultrasonic welding device 4 including the ultrasonic welding bottom die device 100(100a), and the position of the empty cup 80 before the ultrasonic welding is performed is adjusted, so that an ultrasonic welding head 201 of vertical lifting movement included in the ultrasonic welding device 4 is accurately aligned with the bottom of the empty cup 80, and thus ultrasonic welding operation is performed on the water filter (or filter paper placed above the water filter) placed at the bottom of the empty cup 80. The hollow cup 80 is formed in a cylindrical shape having axial symmetry and has an opening at the top.
In the present embodiment, the ultrasonic welding die assembly 100 is disposed below the rotating disk 2 having the hole 2-1 and rotating, and belongs to a part of the ultrasonic welding apparatus 4 shown in fig. 16. A ring of flared lips 83 is formed at the top opening of the hollow cup 80 to rest at the edge of the hole 2-1 through the lips 83. The hole 2-1 of the rotary disc 2 is inserted into and accommodated in the hollow cup 80, then rotated to the upper side of the ultrasonic welding bottom die device 100, and extended into the bottom of the hollow cup 80 through the ultrasonic welding head 201 which moves vertically to perform ultrasonic welding.
Specifically, the ultrasonic welding bottom die device 100 includes: a cup stand component vertically assembled from top to bottom, a supporting seat 30, a driving device 50 connected with and driving the supporting seat 30 to do lifting movement, and a sliding mechanism connected with the supporting seat 30 laterally. The bottom of the supporting seat 30 forms an inverted first adjusting groove 320, and the end of the top rod 501 of the driving device 50 is provided with an adjusting column 502 movably configured to be embedded into the first adjusting groove 320. The driving device 50 is selected from an air cylinder, an electric cylinder, a linear motor or other driving devices with a driving support base 30, and the driving device can be electrically connected with a control system such as a PLC control system or a control system based on a single chip Microcomputer (MCU) through a lead so as to control and drive the cup holder assembly to perform an ascending motion and support the empty cup body 80 when rotating to the upper side of the cup holder assembly according to the hole 2-1 of the rotating disc 2.
Referring to fig. 1, 2, 7 and 8, the cup holder assembly is composed of a cup holder ring 10 and a connecting plate 20 which are vertically assembled, and a plurality of first through holes 121 for compressed air to flow through are formed in the side portion of the cup holder ring 10. The cup supporting ring 10 is provided with a flange 102 transversely near the bottom of the connecting plate 20, the flange 102 forms a plurality of second through holes 103 arranged in a ring shape, and the connecting plate 20 forms a third through hole 203 with internal threads so as to penetrate through the second through holes 103 and the third through hole 203 through bolts. During assembly, bolts may be used to extend through the second through holes 103 and threadably engage with tapped blind holes or tapped through holes (not shown) correspondingly disposed on the upper surface of the connection plate 20. The cup supporting ring 10 is composed of a cup supporting body 101 with an open structure at two ends in the vertical direction, and one or more first through holes 121 can be opened at the side of the cup supporting body 101.
In this embodiment, the top of the cup supporting ring 10 is opened to form a receiving cavity 131 for partially supporting and receiving the empty cup 80, the receiving cavity 131 is higher than the empty cup 80, and forms an annular inclined plane 111 partially attached to the sidewall 82 of the empty cup 80. The bottom 81 of the hollow cup 80 forms a step-shaped contraction portion 812 protruding inward and downward, and is suspended at the bottom of the accommodating cavity 131. The bottom of the annular chamfer 111 forms a ring of steps 112 to support the bottom edge of the empty cup 80 by the steps 112. When the water filter disc is welded to the bottom of the empty cup body 80, only the edge of the water filter disc is welded to the bottom step 811 of the empty cup body. The constricted portion 812 of the hollow cup 80 is suspended in the receiving cavity 131.
The first through hole 121 may be connected with a compressed air introduction pipe (not shown). When ultrasonic welding is performed, because the side wall 82 of the empty cup 80 is tightly attached to the annular inclined surface 111, compressed air can be introduced into the first through hole 121 to separate the side wall 82 from the annular inclined surface 111, so that the empty cup 80 is prevented from jumping in the hole 2-1 of the rotating disc 2 in the process of descending the cup holder assembly, and the stability and smoothness of the whole process of removing the empty cup 80 by the discharging device 5 in fig. 17 after the empty cup 80 is transferred to the hole 2-1 are ensured.
As shown in fig. 1, 2, and 15, the slide mechanism includes: a guide rail 41, a slide block 42 vertically movable up and down along the guide rail, and a mounting block 44 laterally mounted to the slide block. The rotatable disk 2 extends horizontally and laterally into the upper portion of the cup holder assembly. The cup holder assembly is driven by the driving device 50 to reciprocate under the rotating disc 2. The supporting seat 30 is composed of a vertical positioning block 31 partially enclosing the mounting block 44 and a horizontal supporting block 32 arranged below the cup holder assembly, the vertical positioning block 31 forms a second adjusting groove 34 partially accommodating the mounting block 44 along the vertical direction, and the extending direction of the first adjusting groove 320 is parallel to the vertical positioning block 31. As shown in fig. 6, the sliding block 42 is laterally protruded from both sides of the mounting block 44 and a side adjacent to the vertical positioning block 31, so that the mounting block 44 is laterally inserted into the second adjustment groove 34. A blind hole 441 with internal threads is arranged on one side of the mounting block 44 close to the vertical positioning block 31, the vertical positioning block 31 is provided with four through holes 311, and the through holes 311 are horizontally penetrated through by bolts to be screwed with the blind hole 441, so that the supporting seat 30 is mounted on the side part of the mounting block 44. The support base 30 is L-shaped.
The horizontal support block 32 is provided with a plurality of through holes 321, which are vertically arranged, and bolts can be used to penetrate through the through holes 321 from the bottom of the horizontal support block 32 and extend to the through holes 204 with internal threads formed in the connecting plate 20, so as to integrally and fixedly connect the support base 30 with the connecting plate 20 in the cup holder assembly.
As shown in fig. 9 to 12, in the present embodiment, two flanges 3203 are protruded from the bottom of the horizontal supporting block 32 in opposite directions to divide the first adjusting groove 320 into a first sliding cavity 3201 and a second sliding cavity 3202. The width of the first sliding cavity 3201 is greater than the width of the second sliding cavity 3202, and the receiving portion 512 is integrally embedded in the first sliding cavity 3201, and the flange 3203 is vertically clamped by the receiving portion 512 and the abutting column 532. The end formed by the receiving portion 512 and the top wall of the first sliding cavity 3201 are separated from each other, so that a gap 3205 is formed; the pinch post 522 and the flange 3203 are separated from each other, thereby forming a gap 3206. The diameter d4 of the pinch post 522 is less than the width d1 of the flange 3203. The width d2 of the first sliding cavity 3201 is greater than the maximum width d3 of the receiving portion 512 during rotation. The height d5 of the receiving portion 512 along the vertical square is smaller than the depth of the first sliding cavity 3201 along the vertical direction. The receiving portion 512 and the abutting post 532 can jointly clamp the flange 3203 in the vertical direction when the receiving portion 512 is plugged into the first sliding cavity 3201. The shape formed by the cross section of the abutment post 532 is not particularly limited as long as the abutment post 532 can abut laterally against the lower bead of the flange 3203. Because clearance 3205, clearance 3204 and clearance 3206 are formed, it is more convenient not only to make the regulation post 502 transversely fill in first adjustment tank 320, simultaneously because supporting seat 30 and drive arrangement 50 separate from each other and make accessible regulation seat 62 and mount pad 63 along the positional relationship of horizontal direction, finely tune the horizontal position that the regulation post 502 put into first adjustment tank 320, make the axis of ejector pin 501 (being axisymmetric structure) of drive arrangement 50 coincide with the axis of cup stand subassembly all the time, thereby correct the fine setting when ultrasonic bonding die block device 100 and empty cup 80 and hole 2-1 have the off-centre along the vertical direction.
In the present embodiment, the receiving portion 512 is configured as a regular hexagon. During the rotation of the adjusting post 502, a gap 3204 is formed between the side of the receiving portion 512 and the side wall of the first sliding cavity 3201. The accommodating portion 512 can laterally plug the driving device for driving the cup holder assembly into the first adjusting groove 320 through the adjusting column 502 arranged at the top of the driving device from the opening at the two sides of the first adjusting groove 320, so that the cup holder assembly for supporting the empty cup body 80 in the ultrasonic welding bottom die device 100 can be quickly replaced while the height of the cup holder assembly in the initial state can be adjusted by rotating the adjusting column 502 and the ejector rod 501.
Preferably, as shown in fig. 13, the ultrasonic welding die assembly 100 according to the present embodiment further includes: a base adjustment device 60 disposed at the bottom of the driving device 50. The base adjustment device 60 includes: a base 61 for accommodating the guide rail 41, an adjusting seat 62 and a mounting seat 63 partially embedded in the adjusting seat 62. The base 61 is composed of a vertical base 611 and a horizontal base 612, and the vertical base 611 forms a third regulation groove 614 that partially receives the guide rail 41. The adjustment seat 62 forms a fourth adjustment groove 621 that partially receives the mounting seat 63. The mounting seat 63 forms a plurality of first kidney-shaped holes 631, the extending direction of the first kidney-shaped holes 631 is perpendicular to the vertical base 611, the driving device 50 is vertically disposed above the horizontal base 612, and the extending direction of the fourth adjusting groove 621 is perpendicular to the extending direction of the first adjusting groove 320, so as to realize the longitudinal movement of the mounting seat 63 in the fourth adjusting groove 621, and to adjust the relative position between the mounting seat 63 and the adjusting seat 62.
The guide rail 41 is vertically installed in a third adjustment groove 614 vertically disposed on one side of the vertical base 611 facing the driving device 50, the third adjustment groove 614 is provided with a plurality of blind holes 6141 with internal threads, the guide rail 41 is provided with a plurality of through holes 411, and the guide rail horizontally extends through the through holes 411 by using bolts and is fixed with the blind holes 6141 in a threaded manner. The driving device 50 is screwed through the through hole 632 from the bottom of the mounting base 63 and extends into a blind hole (not shown) formed in the bottom of the driving device 50 to connect the driving device 50 and the mounting base 63. Meanwhile, bolts are used to penetrate through the first kidney-shaped hole 631 and are screwed and fixed with the through hole 622 formed in the fourth adjusting groove 621, and the inner wall surface of the through hole 622 may be provided with internal threads or not. Further, the bolt passing through the first kidney-shaped hole 631 further extends downward through the through hole 622 and then is screwed into four through holes 613 with internal threads formed in the horizontal adjustment base 612. Of course, the aforementioned internally threaded through-hole 613 may also be configured as an internally threaded blind hole. Through the technical scheme, the cup holder has the advantages of convenience in installation and reliable structure, and meanwhile, the installation seat 63 is partially accommodated by the fourth adjusting groove 621, and the fourth adjusting groove 621 and the vertical base 611 are vertically arranged, so that the horizontal twisting phenomenon possibly occurring after the driving device 50 is fixed on the installation seat 63 is prevented, and the cup holder assembly can be accurately aligned to the bottom of the hollow cup body 80.
Referring to fig. 8 to 12, in the present embodiment, the adjusting column 502 is composed of a receiving portion 512, a contracting column 522, an abutting column 532 and a stud 542 with external threads, which are coaxially disposed, and is screwed to a blind hole 503 with internal threads formed at an end of the top rod 501 through the stud 542 in a vertical direction, and the adjusting column 502 is selected to adjust a vertical extending distance of the stud 542 extending into the blind hole 503, so as to adjust the top rod 501 to drive the cup holder assembly to rise to an upper limit position and a lower limit position in the vertical direction, thereby adjusting a pressure applied by the bottom of the ultrasonic welding head 201 and the hollow cup 80 and a stroke of the ultrasonic welding head 201, and collecting, verifying and adjusting various welding process parameters such as a welding pressure and a welding effect adopted by the ultrasonic welding head 201.

The stopper 43 is provided with two through holes and is screwed and fixed with a blind hole 312 with internal threads opened at the side of the vertical positioning block 31 by using bolts to penetrate through the through holes. During the process that the driving device 50 drives the cup holder assembly to move upwards, the vertical positioning block 31 synchronously drives the limiting block 45 to move upwards, and the cup holder assembly stops when reaching the set height. The buffer 451 performs buffering and decelerating on an object acting on the buffer 451 through a built-in damper until the object stops, so as to play a protection role. Because of the inertia of the cylinder driving mode, in the embodiment, the applicant skillfully introduces the buffer 451, so that when the cup holder assembly reaches the set height, the top rod of the buffer 451 (which is always located below the limiting block 45) is in contact with the stop block 43, and thus the process of driving the cup holder assembly to perform the ascending motion by the driving device 50 is smoother. The buffer 451 can also be wired to the PLC control system to indicate the current position of the cup holder assembly. The damper 451 may be an electromagnetic damper, a pneumatic damper, or a hydraulic damper.
As shown in fig. 8, 13, 14, and 16, the ultrasonic welding die assembly 100 further includes: a bracket 70 vertically arranged and connected with the base adjusting device 60.
