Description

Technical Field

[0001] The present application relates to the technical field of metal ultrasonic welding, and in particular to an assembly mechanism of a full-wave welding head and an ultrasonic welding machine. Background Art

[0002] The ultrasonic welding machine converts electrical energy into mechanical energy through the energy conversion system, and uses the ultrasonic welding head as the driving component. The part to be welded on the welded part is set between the welding head and the base. Under the action of pressure and amplitude, the high-frequency vibration of the welding head causes atomic diffusion and bonding between the metals, thereby achieving the welding effect, thereby realizing the welding of the joint parts of the welded parts.

[0003] In the prior art, full-wave welding heads usually use screws or top screws to clamp the whole body, so as to complete the fixed assembly of the full-wave welding head. Among them, the full-wave welding head includes a main welding head and a transmission column for supporting the main welding head. However, there are too many components that need to be fixed on the welding head structure, and the manual assembly requirements are high. Once the assembly deviation occurs during the assembly process, the welding head will be misaligned, so that the full-wave welding head structure after installation has slight ultrasonic leakage, and the full-wave welding head installed in this way may be warped, broken, etc. during the welding process. Utility Model Content

[0004] In order to improve the assembly accuracy of a full-wave welding head, the present application provides an assembly mechanism of a full-wave welding head and an ultrasonic welder.

[0007] By adopting the above technical solution, the full-wave welding head and the connecting parts are assembled by using elastic connecting parts, the misalignment of the welding head is corrected and the assembly accuracy of the welding head is improved, the problem of too many assembly components and high manual assembly requirements is solved, and the full-wave welding head is helped to achieve ultrasonic resonance during work.

[0008] Preferably, a boss is provided at the end of the transmission column, a mounting hole is provided on the elastic connecting member, the boss passes through the mounting hole, and the outer diameter of the boss matches the inner diameter of the mounting hole.

[0009] By adopting the above technical solution, the installation of the elastic connecting piece is facilitated by setting the boss, and the thickness of the transmission column of full-wave welding heads of different specifications is different, but the outer diameter of the boss can be customized to be the same, so that full-wave welding heads of different specifications can be installed on the elastic connecting piece.

[0010] Preferably, the connecting member comprises a connecting plate and a connecting block provided on the connecting plate, the elastic connecting member is provided on the connecting block; and further comprises an adjusting assembly, the adjusting assembly comprises an adjusting slot provided on the connecting plate, and a first adjusting column provided on the connecting block, the adjusting slot is provided along the length direction of the transmission column, and the first adjusting column is slidably connected in the adjusting slot.

[0011] By adopting the above technical solution, the distance between the two connecting blocks can be adjusted by adjusting the position of the first adjusting column relative to the adjusting slot, so that full-wave welding heads of different lengths can be used.

[0012] Preferably, a node groove is provided on the transmission column or the connecting member, and a clamping assembly is provided on the connecting member or the transmission column corresponding to the node groove, the clamping assembly includes a clamping member, and the node groove and the clamping member are arranged relative to each other, the node groove is arranged at the node of the transmission column, and the clamping member is used to abut against the node of the transmission column.

[0013] By adopting the above technical scheme, during the operation of the welding machine, the clamping member always presses the transmission column and abuts against the node groove. The setting of the clamping member cooperates with the ultrasonic resonance to ensure that the central axis of the ultrasonic component is on the same axis, and the clamping member slides in the fixed block through the elastic reset member support, so that the rigid support of the clamping member on the transmission column is transformed into flexible support, reducing the impact of the ultrasonic vibration operation of the full-wave welding head on the overall stability of the welding device, ensuring that the clamping member always presses the transmission column and abuts against the node groove during the operation of the welding device, avoiding the welding head from being suspended, reducing the possibility of the full-wave welding head being lifted up and broken during the welding process, and avoiding the welding head from crushing the spring sheet hole fixing position, causing cracks and welding head deviation.

[0014] Preferably, the clamping assembly also includes a connecting block arranged on the connecting member or the transmission column, the connecting block is provided with a guide groove, the clamping member is slidably arranged in the guide groove corresponding to the node groove, and a limiting portion is arranged at the end of the clamping member near the node groove.

[0015] By adopting the above technical solution and providing the limiting portion, it is possible to avoid as much as possible that the abutting piece falls off from the guide groove during the welding process.

[0016] Preferably, a compression spring is arranged in the guide groove, and two ends of the compression spring in the elastic direction abut against the bottom of the guide groove and the abutting member respectively.

[0017] By adopting the above technical solution, the compression spring can be used for buffering and shock absorption, reducing the vibration and impact caused by mechanical movement, and can be used for flexible support of the transmission column to improve the stability of the welding machine during operation.

[0018] Preferably, a contraction cavity is formed at one end of the connecting block away from the clamping member, and the contraction cavity is connected to the guide groove; a piston rod is provided on the clamping member, and the end of the piston rod away from the clamping member passes through the guide groove and is slidably arranged in the contraction cavity.

[0019] By adopting the above technical solution, when the transmission column is working, the vibration drives the abutment to move close to the bottom wall of the guide groove. At this time, the piston rod shrinks to the inside of the contraction chamber. The air in the contraction chamber is compressed due to the pressure of the piston rod, which increases the air pressure in the contraction chamber, thereby causing the piston rod to push the abutment outward, and the abutment is pushed to move toward the node groove on the transmission column until it hits the bottom of the node groove. Therefore, during the operation of the welding device, the abutment always presses the transmission column and hits in the node groove.

[0020] Preferably, a return spring is sleeved on the piston rod, and two ends of the return spring in the elastic direction abut against the bottom of the guide groove and the abutting member respectively.

[0021] By adopting the above technical solution, the setting of the reset spring facilitates the timely reset of the slider, reducing the possibility of insufficient pressing force of the slider against the node groove due to failure of the compressed air between the piston rod and the contraction chamber. In addition, the reset spring is sleeved on the piston rod, which saves installation space compared to the reset spring connected between the piston rod and the top wall of the contraction chamber or arranged outside the piston rod.

[0022] Preferably, a groove is provided on the side wall of the transmission column close to the connecting member, and the connecting member is provided with a top support member corresponding to the groove; the top support member includes a top support rod arranged on the connecting member, and a ball arranged on the top support rod close to the end of the transmission column, and the ball is plug-fitted into the groove.

[0023] By adopting the above technical solution, the setting of the top support rod further enhances the stability of the connection between the connecting plate and the full-wave welding head, reduces the possibility of the full-wave welding head being suspended or offset, and the setting of the ball bearing inserted in the groove is mainly used to cooperate with ultrasonic resonance to improve the safety of welding work.

[0024] On the other hand, an ultrasonic welding machine provided by the present application adopts the following technical solution:

[0025] An ultrasonic welding machine includes a connection drive component, a pressure trigger control component and a full-wave welding head, wherein the pressure trigger control component is installed at the output end of the connection drive component, the full-wave welding head includes a main welding head and a transmission column for supporting the main welding head, and the full-wave welding head is installed at the output end of the pressure trigger control component through the above-mentioned full-wave welding head assembly mechanism, and the two ends of the full-wave welding head are respectively provided with an amplitude modulation device and a balance rod.

[0026] By adopting the above technical solution, the full-wave welding head can be installed using the above-mentioned assembly structure, the misalignment of the welding head can be corrected and the assembly accuracy of the welding head can be improved, the problem of too many assembly components and high manual assembly requirements can be solved, and the full-wave welding head can enter the ultrasonic resonance state more stably during work.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The operator needs to install a welding head that meets the requirements on the welding device according to the welding requirements of the object to be welded. First, rotate the full-wave welding head until the welding head body is vertically downward, and then install the full-wave welding head on the connecting plate on the welding machine through the spring sheet. Since the welding device uses the longitudinal transmission of ultrasonic vibration, the longitudinal transmission is a coaxially installed transducer that harmonizes the energy of ultrasonic vibration through a coaxially connected amplitude modulator and transmits it to the full-wave welding head. At this time, the welding machine works, driving the connecting plate to drive the entire full-wave welding head to touch the object to be welded, and welding can be achieved. After the transducer and the amplitude modulation device are coaxially connected to the end of the transmission column, in order to maintain the balanced vibration of the full-wave welding head during operation, an elastic fastening member is set between the transmission column and the connecting plate to correct the misalignment of the welding head and improve the assembly accuracy of the welding head, solve the problem of too many assembly components and high requirements for manual assembly, and help the full-wave welding head reach an ultrasonic resonance state during work.

[0029] 2. During the operation of the welding machine, the slider always presses the transmission column and contacts the node groove. The setting of the slider cooperates with the ultrasonic resonance to ensure that the central axis of the ultrasonic component is on the same axis, and the slider slides in the fixed block through the elastic reset member to support the sliding of the slider on the transmission column. The rigid support of the slider on the transmission column is transformed into a flexible support, reducing the possibility of warping and breaking of the full-wave welding head during the welding process, and reducing the impact of the ultrasonic vibration of the full-wave welding head on the overall stability of the welding device.

[0041] The connecting member 2 includes a connecting plate 21, which is in the shape of a rectangular plate as a whole. Two connecting blocks 22 are vertically arranged on one side of the connecting plate 21 close to the full-wave welding head 1, and the two connecting blocks 22 are respectively arranged on the two short-dimension sides of the connecting plate 21. The main welding head 111 and the spare welding head 112 are both arranged between the two connecting blocks 22, and in this embodiment, the spare welding head 112 is arranged close to the connecting plate 21, and the connecting plate 21 is provided with a clearance groove 211 corresponding to the spare welding head 112. A fan-shaped clearance opening is provided on the side of the connecting block 22 away from the connecting plate 21, and the elastic connecting member 3 is installed on the outer sides of the two connecting blocks 22 that are separated from each other by bolts and a pressure ring.

[0042] The elastic connector 3 can be set as a circular spring sheet or a fan-shaped spring sheet, and when it is set as a fan-shaped spring sheet, the open mouth of the fan-shaped spring sheet faces the object to be welded, so that the fan-shaped spring sheet can be used to avoid. A mounting hole 31 is set at the center of the elastic connector 3, and bosses 121 are coaxially fixedly set on the end faces of both ends of the transmission column 12. The elastic connector 3 is sleeved on the boss 121 through the mounting hole 31, and the shape of the boss 121 matches the inner diameter of the mounting hole 31.

[0043] An arcuate groove 122 is provided on the side wall of the transmission column 12 near the connecting block 22, and a supporting member 5 is provided on the corresponding groove 122 of the connecting block 22. The supporting member 5 includes a supporting rod 51 and a ball 52. The supporting rod 51 passes through the connecting block 22 and is fixed to the end of the connecting block 22 away from the connecting member 2 by bolts. The ball 52 is rotatably embedded in the end of the supporting rod 51 extending out of the connecting block 22 and located in the clearance opening. The ball 52 and the groove 122 are plug-fitted, and the ball 52 is set to abut against the bottom of the groove 122 to enhance the stability of the welding work.

[0044] Two sets of abutment components 4 are also arranged on the same side of the connection plate 21 where the connection block 22 is arranged, and the abutment components 4 are arranged on the inner side of the fixing block 41 close to the clearance groove 211. Figure 3The clamping assembly 4 includes a fixed block 41 and a clamping member 42. An arc-shaped node groove 123 is provided on the side of the transmission column 12 close to the connecting plate 21, corresponding to the clamping member 42. A guide groove 411 is provided in the fixed block 41 on one side facing the node groove 123 in a vertical direction perpendicular to the connecting plate 21, and the clamping member 42 is movably arranged in the guide groove 411. The node groove 123 is arranged at the node of the transmission column 12, and the clamping member 42 is used to abut against the node of the transmission column 12. A limiting portion 412 is integrally formed at the open portion of the fixed block 41 close to the guide groove 411, and a section of the clamping member 42 close to the bottom of the guide groove 411 is integrally formed with a clamping block 43. When the clamping member 42 moves toward the transmission column 12, the clamping block 43 can abut against the limiting portion 412, thereby preventing the clamping member 42 from falling off from the fixed block 41. By utilizing the principle of gas compression, when the transmission column 12 is working, the vibration drives the clamping member 42 to move toward the bottom of the guide groove 411. The gas in the guide groove 411 is compressed due to the compression movement of the clamping member 42, so that the air pressure in the guide groove 411 increases, thereby causing the clamping member to move toward the transmission column 12, thereby realizing the elastic reciprocating motion of the clamping member 42 relative to the guide groove 411.

[0045] Preferably, the abutting assembly 4 further includes a compression spring 44, the two ends of which in the elastic direction are respectively abutted against the abutting member 42 and the bottom of the guide groove 411, and when the compression spring 44 is in a natural state, the abutting block 43 is abutted against the limiting portion 412. In addition, a rubber pad 421 is fixedly provided on one side of the abutting member 42 facing the node groove 123, and the rubber pad 421 is used to reduce the wear between the abutting member 42 and the transmission column 12.

[0046] refer to Figure 4 In addition, in order to adapt to full-wave welding heads 1 of different lengths, the present embodiment further includes an adjustment component 6, which includes an adjustment slot 61 provided on the connecting plate 21, a plurality of first adjustment columns 62 provided on the side of the connecting block 22 away from the full-wave welding head 1, and a plurality of second adjustment columns 63 provided on the fixed block 41 away from the full-wave welding head 1, and the first adjustment column 62 and the second adjustment column 63 are both slidably connected in the adjustment slot 61. The length direction of the adjustment slot 61 is parallel to the length direction of the transmission column 12, and in the present embodiment, there are four adjustment slots 61, two in a group, and the two groups of adjustment slots 61 are distributed at both ends of the length direction of the connecting plate 21. The first adjustment column 62 and the second adjustment column 63 can be fixedly provided on the connecting plate 21 by bolts, and by adjusting the positions of the first adjustment column 62 and the second adjustment column 63 in the adjustment slot 61, the distance between the connecting blocks 22 and the distance between the fixed blocks 41 can be adjusted to adapt to full-wave welding heads 1 of different lengths.

[0047] The implementation principle of the assembly mechanism of a full-wave welding head in Example 1 of the present application is as follows: when installing the full-wave welding head 1, firstly, the full-wave welding head 1 needs to be rotated to the point where the main welding head 111 or the spare welding head 112 is vertically downward to meet the welding requirements of different objects to be welded; and then the boss 121 is fixed together by the elastic connector 3 in cooperation with the top support rod 51, thereby fixing the transmission column 12. At the same time, the sliding abutment 42 on the connector 2 is inserted into the node groove 123 under the elastic abutment of the compression spring 44, and contacts the bottom of the node groove 123, so as to ensure as much as possible that during the operation of the welding device, the abutment 42 always presses the transmission column 12 and contacts the node groove 123.

[0048] Embodiment 2:

[0049] Embodiment 2 of the present application discloses an assembly mechanism for a full-wave welding head.

The contraction chamber 413 is provided at one end of the guide groove 411 away from the clamping block. The piston rod 45 is provided at the clamping member 42 close to the contraction chamber 413, the length direction of the piston rod 45 is parallel to the moving direction of the clamping member 42, and the end of the piston rod 45 away from the clamping member 42 is provided in the contraction chamber 413. In addition, a return spring 46 is sleeved on the piston rod 45, and the two ends of the return spring 46 in the elastic direction are respectively abutted against the bottom of the guide groove 411 and the clamping member 42.

[0051] The implementation principle of the assembly mechanism of a full-wave welding head in Example 2 of the present application is: using the principle of gas compression, when the transmission column 12 is working, the vibration drives the clamping member 42 to move toward the bottom of the guide groove 411, and at this time the piston rod 45 shrinks into the contraction chamber 413. Due to the compression movement of the piston rod 45, the air in the contraction chamber 413 is compressed, which increases the air pressure in the contraction chamber 413, thereby causing the piston rod 45 to push the clamping block outward.

[0054] refer to Figure 6 An ultrasonic welding machine includes a connecting drive component 71, a pressure trigger control component 72 and a full-wave welding head 1, wherein the pressure trigger control component 72 is installed at the output end of the connecting drive component 71. The full-wave welding head 1 is installed at the output end of the pressure trigger control component 72 through the above-mentioned assembly mechanism, wherein the connecting member 2 is connected to the output end of the pressure trigger control component 72.

[0055] One end of the transmission column 12 is coaxially connected to a transducer and an amplitude modulation device 73, and the end of the transmission column 12 away from the amplitude modulation device 73 is coaxially fixed with a balance bar 74. The balance bar 74 amplifies the mechanical vibration or speed and concentrates the ultrasonic energy on a smaller area, so that the overall resonant output of the full-wave welding head 1, the amplitude modulation device 73 and the balance bar 74 meets the vibration standard.

[0056] The implementation principle of the assembly mechanism of a full-wave welding head in Example 3 of the present application is as follows: the full-wave welding head 1 is installed on the output end of the pressure trigger control component 72 through the above-mentioned assembly mechanism, thereby improving the assembly accuracy of the full-wave welding head 1 on the ultrasonic welding machine; when the connection drive component 71 is started to work, the pressure trigger control component 72 generates pressure data and triggers welding, and the full-wave welding head 1 can avoid warping, breakage, etc. during the welding process as much as possible.
