Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding equipment, and more specifically, to a robotic ultrasonic welding device. Background Technology

[0002] Ultrasonic welding equipment for robotic arms is an automated system that combines robotic arm motion control with ultrasonic welding technology. Ultrasonic welding equipment is an advanced technology that uses high-frequency vibration energy to achieve material joining. It is suitable for welding thermoplastics, metals and composite materials, requires no solder, is environmentally friendly and produces strong joints. It covers industries such as electronics, automotive, medical and packaging, and is especially suitable for scenarios in automated production lines with high requirements for speed and quality.

[0003] Existing robotic ultrasonic welding equipment has some problems in practical use. For example, an ultrasonic welding device with a robotic arm, disclosed in CN217803392U, can be placed in the usage location, but the device is large and requires multiple workers to move it when it needs to be moved to the usage location, which is cumbersome and inconvenient for convenient transfer and use. At the same time, the workpiece can be clamped and limited by the side clamps, but the limiting effect is poor. During processing, the workpiece is prone to displacement and separation, which affects the processing effect and makes it inconvenient to conveniently limit and clamp the workpiece.

[0004] Therefore, we have made improvements to this and proposed a robotic ultrasonic welding device. Utility Model Content

[0005] The purpose of this utility model is to address the current problems of inconvenient equipment transfer and use, and inconvenient material clamping and limiting.

[0006] To achieve the above objectives, the present invention provides the following technical solution: Robotic ultrasonic welding equipment is used to improve the above problems.

[0007] The application is as follows: An ultrasonic welding device for robotic arms includes a mounting box with wheels at the bottom. The mounting box contains a tray for placing materials to be welded, clamping assemblies arranged on both sides of the tray, and an ultrasonic welding machine. The clamping assemblies include two opposing clamping plates, two pairs of opposing clamping blocks, and a clamping drive unit. Each pair of clamping blocks is slidably connected to the mounting plate. The clamping drive unit drives the two mounting plates to move towards each other or away from each other. Each clamping plate slides along the inner wall of the mounting box at both ends and has two through slots. Each pair of clamping blocks has a right-angled triangular cross-section that passes through the through slot of the corresponding clamping plate and partially extends to the other side of the clamping plate. The inclined surfaces of the two clamping plates in each pair are far apart from each other. In the initial state, the inclined surfaces of the two clamping plates in each pair abut against the outside of the through slot of the clamping plate.

[0008] Preferably, the clamping drive unit includes a first self-locking motor and a bidirectional threaded rod connected to the output shaft of the first self-locking motor; the bidirectional threaded rod is provided with two connecting blocks, and the two mounting plates move towards each other or away from each other along the bidirectional threaded rod through the corresponding connecting blocks.

[0009] The mounting plate has two axially extending grooves. Each groove contains a first spring and a guide block. One end of the first spring is fixedly connected to one side of the groove, and the other end is connected to the guide block. Both ends of the guide block pass through the groove. The clamping block is fixedly connected to the guide block.

[0010] A guide rod is provided through the facing surfaces of the two clamping plates. One end of the guide rod is connected to the clamping plate, and the other end is provided with a limiting head.

[0011] The mounting box has positioning slots on both sides, and a connecting frame and two push plates are rotatably mounted in the positioning slots. The two push plates are arranged vertically and one end is rotatably connected to the connecting frame. The other end of the two push plates is rotatably connected to a vertical plate. A pressing block is fixedly connected to the outside of the vertical plate. The pressing block has a first inclined surface. An extension plate is provided on one side of the pressing block. The extension plate has a second inclined surface opposite to the first inclined surface. The lower part of the extension plate extends to the mounting box and is connected to a support plate.

[0012] A limiting plate is connected to the outer side of the extension plate, and a second spring is connected between the limiting plate and the bottom of the positioning groove.

[0013] A second self-locking motor is provided on the outside of the mounting box, which drives the connecting frame to rotate; the side end face of the upright plate slides along the inner side of the mounting box.

[0014] A hydraulic cylinder is provided on one side of the mounting box, a splicing plate is mounted on the hydraulic cylinder, an ultrasonic welding machine is mounted on the splicing plate, and a welding head is mounted on the ultrasonic welding machine.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The clamping drive unit uses the clamping block to push the two clamping plates to move towards each other to clamp the left and right sides of the workpiece. At the same time, the part of the clamping block that extends out of the through slot of the clamping plate can clamp the front and back of the workpiece, thus realizing reliable limiting clamping of the workpiece. (2) When moving the installation box, the installation box is equipped with pulleys for auxiliary movement and transportation. When it needs to be supported and fixed after being moved to the use position, the second self-locking motor can be turned on to drive the connecting frame to rotate. The push plates on both sides of the connecting frame can push the upright plate outward. The pressing block on the upright plate can cooperate with the inclined surface to drive the extension plate down. The limiting plate on the extension plate squeezes the second spring. The support plate on the extension plate can be attached to the ground for support. The moving wheels can be lifted up to avoid the moving pulleys affecting the stability of use.

[0023] like Figure 1-6 As shown, this embodiment proposes a robotic ultrasonic welding device, including a mounting box 1. A tray 2 is fixedly connected to the middle of the mounting box 1 for placing the workpiece to be welded. A bidirectional threaded rod 4 extends in the left-right direction inside the mounting box 1, such as... Figure 4 As shown, one end of the bidirectional threaded rod 4 is rotatably connected to the mounting box 1, and the other end is connected to a first self-locking motor 3. The first self-locking motor 3 drives the bidirectional threaded rod 4 to rotate. Connecting blocks 5 are threaded onto both threads of the bidirectional threaded rod 4, and a mounting plate 6 is fixedly connected to each connecting block 5. Figure 3 As shown, in a preferred embodiment, the bottom surface of the connecting block 5 is in contact with the bottom surface inside the mounting box 1, which ensures that the connecting block 5 can move smoothly by being supported by the contact of the bottom surface inside the mounting box 1 when moving left and right.

[0024] Please combine Figure 1 and Figure 5 Two clamping blocks 9 are symmetrically and slidably arranged on a single mounting plate 6, and the cross-section of a single clamping block 9 is a right-angled triangle. Simultaneously, a clamping plate 10 is also provided on the inner side of the two mounting plates 6 (i.e., the side closer to the support plate 2). The clamping plate 10 can slide along the inner wall of the mounting box 1. In one embodiment, the inner wall of the mounting box 1 has a clamping plate groove, and both ends of the clamping plate 10 are disposed in the groove and slide along the groove. Symmetrically arranged through slots are formed on the clamping plate 10, and a single clamping block 9 extends through the corresponding through slot to the inner side of the clamping plate 10, with the inclined surface of the clamping block 9 abutting against the support plate 2. On the outside of the through groove of the clamping plate 10, a right-angled surface of each of the four clamping blocks 9 is respectively arranged around the front and rear sides of the workpiece; thus, as the two mounting plates 6 move towards each other, the inclined surfaces of the clamping blocks 9 abut against the outside of the through groove of the clamping plate 10, and the clamping blocks 9 can push the clamping plate 10 to move towards each other. After the clamping plate 10 moves and clamps the workpiece, under the push of the mounting plate 6, the through groove of the clamping plate 10 limits the clamping blocks 9, so that the two clamping blocks 9 located on the same mounting plate 6 move towards each other, thereby clamping the workpiece from front to back. Example

[0025] In this embodiment, please refer to Figure 3 and Figure 5 Based on embodiment 1, a single mounting plate 6 has two axially extending grooves. A first spring 7 is fixedly connected in the grooves, and a guide block 8 is fixedly connected to the other end of the first spring 7. The two ends of the guide block 8 pass through the grooves to the left and right, and can also move back and forth along the grooves. The clamping block 9 is fixedly connected to the guide block 8 and slides back and forth along the grooves through the guide block 8. The first spring 7 ensures that the clamping block 9 can smoothly push the clamping plate 10 to move.

[0026] In addition, such as Figure 4 As shown, a guide rod 11 is provided through the mounting plate 6. One end of the guide rod 11 is connected to the clamping plate 10, and the other end of the guide rod 11, which passes through the mounting plate 6, is provided with a limiting head, which helps to limit the travel of the clamping plate 10 to a certain extent. Example

[0027] Please see Figure 2 , Figures 4-6This application also proposes a mechanism for stabilizing the device, namely, a support plate 20 is attached to the ground for support, avoiding the impact of moving pulleys on the stability of use. Specifically, positioning grooves are provided on both sides of the mounting box 1, and a connecting frame 13 and two push plates 14 are rotatably mounted in the positioning grooves; the two push plates 14 are arranged vertically and one end of each is rotatably connected to the connecting frame 13, and the other end of the two push plates 14 is rotatably connected to a vertical plate 15, and a pressing block 16 is fixedly connected to the outside of the vertical plate 15; the pressing block 16 has a first inclined surface; an extension plate 19 is provided on one side of the pressing block (16), and the extension plate 19 has a second inclined surface opposite to the first inclined surface; the lower part of the extension plate 19 extends to the mounting box 1 and is connected to the support plate 20.

[0028] Furthermore, a second self-locking motor 12 is installed on the mounting box 1. The output shaft of the second self-locking motor 12 is fixedly connected to the connecting frame 13. The second self-locking motor 12 drives the connecting frame 13 to rotate inside the mounting box 1. The push plate 14 pulls the corresponding upright plate 15 closer or pushes it away. The upright plate 15 also drives the pressing block 16 to be pulled closer or pushed away. Through the cooperation between the pressing block 16 and the inclined surface of the extension plate 19, when the pressing block 16 is pushed away, it applies downward pressure to the extension plate 19 and pushes out the support plate 20.

[0029] Furthermore, a second spring 17 is fixedly connected inside the mounting box 1, and a limiting plate 18 is fixedly connected to the other end of the second spring 17. The limiting plate 18 is connected to the extension plate 19, and the second spring 17 provides a certain restoring force to the extension plate 19.

[0030] In other embodiments, such as Figure 6 As shown, in a preferred embodiment, a splicing plate 22 is mounted on the hydraulic cylinder 21, an ultrasonic welding machine 23 is mounted on the splicing plate 22, and a welding head 24 is mounted on the ultrasonic welding machine 23.

[0031] Specifically, when using this robotic ultrasonic welding equipment: (in conjunction with...) Figure 1-6 When moving the installation box 1, the installation box 1 is equipped with pulleys for auxiliary movement and transportation. When it needs to be supported and fixed after being moved to the use position, the second self-locking motor 12 can be turned on to drive the connecting frame 13 to rotate. The push plates 14 on both sides of the connecting frame 13 can push the upright plate 15 to move outward respectively. The pressing block 16 on the upright plate 15 can cooperate with the inclined surface to drive the extension plate 19 to move downward. The limiting plate 18 on the extension plate 19 presses the second spring 17. The support plate 20 on the extension plate 19 can be attached to the ground for support, so as to avoid the pulleys affecting the stability of use during movement.

[0032] When limiting the material, the material can be placed on the pallet 2. When the first self-locking motor 3 drives the bidirectional threaded rod 4 to rotate, the connecting blocks 5 on both sides drive the mounting plate 6 to move inward. The clamping plate 10 set on the mounting plate 6 can clamp the material from left to right. When the mounting plate 6 continues to move, it applies pressure to the clamping plate 10. The through hole of the clamping plate 10 can push the inclined surfaces of the clamping blocks 9 on both sides to move inward. When the clamping plate 10 moves, it can move smoothly by the guidance and support of the guide rod 11. When the clamping block 9 moves, it can squeeze the first spring 7 by the guide block 8. The clamping blocks 9 on both sides can clamp the material from front to back, which can improve the installation and limiting effect. The hydraulic cylinder 21 drives the splicing plate 22 to move down, and the welding head 24 on the welding component 23 is attached to the material, which can be subjected to ultrasonic welding processing.

[0033] The reverse direction drives the bidirectional threaded rod 4 to rotate, and the mounting plates 6 connected on both sides move outward. The clamping plate 10 is not blocked by the material. Under the push of the first spring 7, the guide block 8 and the clamping block 9 are reset, releasing the clamped material for subsequent clamping. The equipment can be controlled by the panel controller.

[0034] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, as well as all technical solutions and improvements that do not depart from the spirit and scope of practicality, are covered within the scope of the claims of the present utility model.
