Metal ultrasonic welding seat

Abstract

This utility model provides a metal ultrasonic welding base, belonging to the field of ultrasonic welding technology. It includes a base with a clamping mechanism on its top. Two clamping plates connected to the clamping mechanism are mounted on the top of the base. The top of the base has two receiving grooves, each containing a pushing mechanism. Each pushing mechanism includes multiple springs within the receiving grooves and a lifting plate on top of the springs. The lifting plate has a grid pattern on its top and sloped ends. This utility model uses the grid pattern on the top of the lifting plate to isolate the workpiece from the base, preventing excessive adhesion. After the clamping mechanism releases the workpiece, the spring force causes the lifting plate to rise, completely separating the workpiece from the base, allowing for easy removal of the workpiece and increasing practicality.

Description

Technical Field

[0001] This utility model mainly relates to the field of ultrasonic welding technology, and specifically to a metal ultrasonic welding seat. Background Technology

[0002] The working principle of an ultrasonic metal welding machine is to use the mechanical vibration energy of ultrasonic waves (frequency exceeding 16KHz) to transmit along the rigid metal material to two closely attached objects that need to be welded. Under pressure, the surfaces of the two objects rub against each other, causing the molecular layers to penetrate and intertwine. The molecular lattices of the two weldment surfaces enter each other and recombine, thus forming a tight bond.

[0003] When welding metal, the welding stand needs to clamp the metal. However, in traditional ultrasonic welding stands, during high-power welding, the metal layer can stick to the welding stand due to the high temperature generated by friction. This causes the workpiece to stick to the welding stand after welding, making it difficult to remove the workpiece easily. Utility Model Content

[0004] This utility model mainly provides a metal ultrasonic welding base to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A metal ultrasonic welding base includes a base, a clamping mechanism is provided on the top of the base, and two clamping plates connected to the clamping mechanism are installed on the top of the base.

[0007] The base has two receiving slots on its top, and each of the two receiving slots is equipped with a pushing mechanism. The pushing mechanism includes multiple springs installed in the receiving slots and a lifting plate installed on top of the springs. The top of the lifting plate is provided with grid stripes, and both ends of the lifting plate are sloping structures.

[0008] Optionally, mounting plates are provided on both sides of the bottom of the base, and each mounting plate has two positioning holes.

[0009] Optionally, the opening width of the receiving groove is smaller than the internal width, and the pushing mechanism further includes a movable plate disposed in the receiving groove and connected to the lifting plate, wherein the width of the movable plate is greater than the opening width of the receiving groove.

[0010] Optionally, the pushing mechanism further includes multiple fixed shafts equidistantly arranged at the bottom of the receiving groove, and the bottom of the multiple springs are sleeved on the multiple fixed shafts.

[0011] Optionally, a sliding groove is provided on the top of the base between the two receiving grooves, and the clamping mechanism includes a positive and negative lead screw rotatably connected to the sliding groove, two lead nuts symmetrically slidably connected to the positive and negative lead screw, a motor connected to the positive and negative lead screw, and two connecting plates respectively installed on the top of the two lead nuts; the two clamping plates are respectively connected to the two connecting plates.

[0012] Optionally, the top of the connecting plate is provided with a threaded shaft, and the clamping plate is connected to the threaded shaft by internal and external threads.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model can effectively clamp the workpiece through a clamping mechanism and a clamping plate. The top of the base is equipped with a lifting plate. Since the grid stripes on the top of the lifting plate play a role in isolating the workpiece from the base, the workpiece will not stick to the base excessively. After the clamping mechanism releases the workpiece, the lifting plate is raised by the force of the spring, so that the workpiece is completely separated from the base. Then the workpiece can be easily removed, which increases its practicality.

[0015] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] This application provides a metal ultrasonic welding stand, as shown in the schematic diagram below. Figure 1-4 As shown. Metal ultrasonic welding base; including base 10, a clamping mechanism 30 is provided on the top of base 10, and two clamping plates 40 connected to the clamping mechanism 30 are installed on the top of base 10.

[0025] The top of the base 10 is provided with two receiving slots 11, and each of the two receiving slots 11 is provided with a pushing mechanism 20. The pushing mechanism 20 includes multiple springs 23 provided in the receiving slots 11 and a lifting plate 21 provided on the top of the springs 23. The top of the lifting plate 21 is provided with grid stripes, and both ends of the lifting plate 21 are sloping structures.

[0026] It should also be noted that all electrical components in this device are externally powered and electrically connected to a conventional PLC controller.

[0027] For details, please refer to the appendix. Figure 1 The base 10 has mounting plates 50 on both sides of the bottom, and each mounting plate 50 has two positioning holes.

[0028] It should be noted that, in this embodiment, the welding seat can be installed on a desktop by installing threads in the positioning holes on the mounting plate 50.

[0029] For details, please refer to the appendix. Figure 2The opening width of the receiving groove 11 is smaller than the internal width. The pushing mechanism 20 also includes a movable plate 22 disposed in the receiving groove 11 and connected to the lifting plate 21. The width of the movable plate 22 is greater than the opening width of the receiving groove 11.

[0030] It should be noted that in this embodiment, the movable plate 22 is confined within the receiving groove 11, thereby limiting the lifting distance of the lifting plate 21, thus better separating the metal and the welding seat.

[0031] For details, please refer to the appendix. Figure 2 The feeding mechanism 20 also includes multiple fixed shafts 24 that are equidistantly arranged at the bottom of the receiving groove 11, and multiple springs 23 are fitted onto the multiple fixed shafts 24 at their bottoms.

[0032] It should be noted that in this embodiment, the spring 23 can be restricted by the fixed shaft 24 to prevent the spring 23 from tilting and failing to rebound.

[0033] For details, please refer to the appendix. Figure 3 The base 10 between the two receiving slots 11 has a sliding groove 12 on its top. The clamping mechanism 30 includes a positive and negative lead screw 31 rotatably connected to the sliding groove 12, two lead nuts 32 symmetrically slidably connected to the positive and negative lead screw 31, a motor 33 connected to the positive and negative lead screw 31, and two connecting plates 34 respectively installed on the top of the two lead nuts 32; the two clamping plates 40 are respectively connected to the two connecting plates 34.

[0034] It should be noted that in this embodiment, the operation of the motor 33 can cause the positive and negative lead screws 31 to rotate. Since the threads at both ends of the positive and negative lead screws 31 are opposite, the two lead nuts 32 will move closer or further away from each other, thereby causing the clamping plate 40 to clamp the metal and change the position of the lifting plate 21.

[0035] For details, please refer to the appendix. Figure 4 The top of the connecting plate 34 is provided with a threaded shaft 35, and the clamping plate 40 is connected to the threaded shaft 35 by internal and external threads.

[0036] It should be noted that, in this embodiment, since the types of metals to be ultrasonically welded are different and have different shapes, the clamping plate 40 can be disassembled and then a suitable clamping plate 40 can be installed to clamp the metals with different shapes, thus ensuring the ultrasonic welding effect.

[0037] The specific operation method of this utility model is as follows:

[0038] First, place the metal to be welded between the two clamping plates 40 of the base 10, and then start the clamping mechanism 30 to weld the metal. When the connecting plate 34 is in the middle section of the lifting plate 21, the top height of the lifting plate 21 is the same as the top height of the base 10.

[0039] After clamping, ultrasonic welding is performed. After welding, the grid stripes on the top of the lifting plate 21 act as a barrier between the workpiece and the base 10, preventing the workpiece from sticking excessively to the base 10. Then, the clamping mechanism 30 operates again to release the workpiece. As the connecting plate 34 moves outward, the lifting plate 21 loses downward pressure. The lifting plate 21 rises due to the force of the spring 23, thus completely separating the workpiece from the base 10. The workpiece can then be easily removed.

[0040] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
