Description

Technical Field

[0001] This application relates to the field of ultrasonic welding technology, and in particular to a wire-blocking mechanism. Background Technology

[0002] An ultrasonic welding machine is a device that uses high-frequency vibration waves to transmit energy to a workpiece. The friction between the workpiece surface and molecules generates high temperatures, which rapidly melt the workpiece interface. The workpiece is then cooled and shaped under certain pressure to achieve welding. It has the advantages of fast welding speed, high welding strength, and high level of automation.

[0003] During the welding process of terminals, since the end of the terminal is a wire bundle, a wire-blocking mechanism needs to be installed on the ultrasonic welding machine. The distance between the welding bundle and the wire bundle is controlled by the wire-blocking mechanism, thereby controlling the welding length. The wire-blocking mechanism is usually a baffle plate that is fixedly connected to the ultrasonic welding machine.

[0004] During the welding process, the fixed position of the baffle plate results in poor flexibility, leading to a small control range of the wire harness by the wire-blocking mechanism, which affects the final welding effect. Summary of the Invention

[0005] To help solve the problem that the fixed position of the baffle plate results in poor flexibility, leading to a small control range of the wire harness by the wire-blocking mechanism and affecting the final welding effect, this application provides a wire-blocking mechanism with the following technical solution: it includes a connecting plate, on which a mounting plate is slidably connected, and the connecting plate is provided with a sliding unit for driving the mounting plate to slide. A connecting frame is rotatably connected to the mounting plate, and the baffle plate is disposed on the connecting frame. The mounting plate is provided with a driving unit for driving the connecting frame to rotate.

[0006] In one specific implementation, the sliding unit includes a slide cylinder mounted on a connecting plate, and the mounting plate is located at the output end of the slide cylinder.

[0007] In one specific implementation scheme, the mounting plate is provided with a support base, the connecting frame is provided with a connecting hole, a pin is inserted through and rotatably connected to the connecting hole, and the end of the pin facing the support base is rotatably connected to the support base.

[0008] In one specific implementation, the support base includes a first support block disposed on a mounting plate. An arc-shaped block is provided at one end of the first support block away from the mounting plate, and a second support block is provided at one end of the arc-shaped block away from the first support block. There is a gap between the first support block and the second support block, and a pin is rotatably connected between the first support block, the second support block, and the arc-shaped block. A set screw is threaded through and connected to the arc-shaped block, and the end of the set screw facing the pin contacts the outer edge of the pin.

[0009] In one specific implementation scheme, a stabilizing bolt is provided on the second support block, and a mounting groove matching the stabilizing bolt is opened on the surface of the first support block facing the second support block. The end of the stabilizing bolt facing the mounting groove is threaded into the mounting groove.

[0010] In one specific implementation, a steel sleeve matching the connection hole is provided inside the connection hole, and the pin is rotatably connected to the inner edge of the steel sleeve.

[0011] In one specific implementation, the drive unit includes a telescopic cylinder rotatably connected to a mounting plate, and the connecting frame is rotatably connected to the output end of the telescopic cylinder via a transmission assembly.

[0012] In one specific implementation, the transmission assembly includes a mounting bracket disposed at the output end of the telescopic cylinder, the mounting bracket having a mounting shaft, the connecting frame having a mounting hole matching the mounting shaft, and the mounting shaft being rotatably connected within the mounting hole.

[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0020] This application discloses a guide rail mechanism.

[0021] Reference Figure 1 and Figure 2 The guide wire mechanism includes a connecting plate 1 connected to the machine base, a mounting plate 4 slidably connected to the connecting plate 1, a sliding unit for driving the mounting plate 4 to slide on the connecting plate 1, the sliding unit including a slide cylinder 5 mounted on the connecting plate 1, the mounting plate 4 being bolted to the output end of the slide cylinder 5, a connecting frame 3 being rotatably connected to the mounting plate 4, a baffle 2 being mounted on the connecting frame 3, and a drive unit for driving the connecting frame 3 to rotate on the mounting plate 4.

[0022] Therefore, starting the slide cylinder 5 causes the mounting plate 4 at the output end of the slide cylinder 5 to slide, thereby causing the connecting frame 3 and the baffle 2 to slide synchronously, realizing the adjustment of the horizontal position of the baffle 2. Starting the drive unit causes the connecting frame 3 to rotate relative to the mounting plate 4, thereby causing the baffle 2 on the connecting frame 3 to rotate synchronously, realizing the adjustment of the angle of the baffle 2, improving the flexibility of the position of the baffle 2, increasing the control range of the wire harness by the wire-blocking mechanism, and facilitating the control of the welding length, thereby improving the welding effect.

[0023] Reference Figure 1 and Figure 2 The top of the connecting frame 3 is provided with a sliding groove 16. An adjusting rod 17, matching the size of the sliding groove 16, is slidably connected within the sliding groove 16. A baffle 2 is bolted to the adjusting rod 17. The connecting frame 3 is provided with a fixing unit for fixing the position of the adjusting rod 17. The fixing unit includes an oblong hole 18 on the adjusting rod 17, through which an adjusting bolt passes. The bottom of the sliding groove 16 is provided with an adjusting groove 19 matching the size of the adjusting bolt. One end of the adjusting bolt facing the adjusting groove 19 is threaded into the adjusting groove 19. Therefore, the operator can remove the adjusting rod 17 from the connecting frame 3 by unscrewing the bolt, making the adjusting rod 17 and the baffle 2 detachable. The position of the adjusting rod 17 in the sliding groove can be easily and conveniently adjusted through the oblong hole 18, providing greater flexibility.

[0024] Reference Figure 1 and Figure 2The mounting plate 4 is provided with a support base 6, and the connecting frame 3 is provided with a connecting hole 7. A pin 8 is inserted and rotatably connected in the connecting hole 7. In this embodiment, the pin 8 can be a shouldered pin 8, which reduces the possibility of impurities entering between the pin 8 and the connecting hole 7 and improves compactness. The support base 6 includes a first support block 9 provided on the mounting plate 4. An arc-shaped block 10 is fixedly connected to one end of the first support block 9 away from the mounting plate 4. A second support block 11 is fixedly connected to one end of the arc-shaped block 10 away from the first support block 9. There is a gap between the first support block 9 and the second support block 11, and the pin 8 is rotatably connected between the first support block 9, the second support block 11 and the arc-shaped block 10. A set screw is inserted and threaded on the arc-shaped block 10. The end of the set screw facing the pin 8 contacts the outer edge of the pin 8. The end of the set screw limits the position of the pin 8 and reduces the possibility of the pin 8 shifting position and causing positional deviation.

[0025] Reference Figure 1 and Figure 2 A stabilizing bolt is mounted on the second support block 11. A mounting groove matching the size of the stabilizing bolt is formed on the surface of the first support block 9 facing the second support block 11. One end of the stabilizing bolt, facing the mounting groove, passes through the gap between the first support block 9 and the second support block 11 and is threaded into the mounting groove. Therefore, the operator can adjust the gap between the first support block 9 and the second support block 11 by rotating the stabilizing bolt, thereby tightening the pin 8, reducing the possibility of pin 8 displacement, and improving the stability of the connecting frame 3 when rotating along the pin 8.

[0026] Reference Figure 1 and Figure 2 A steel sleeve 12 matching the size of the connecting hole 7 is installed inside the connecting hole 7. The pin 8 is rotatably connected to the inner edge of the steel sleeve 12. In this embodiment, the steel sleeve 12 is made of SKD11 mold steel material, which has high hardness, excellent wear resistance and good toughness.

[0027] Reference Figure 1 and Figure 2 The drive unit includes a telescopic cylinder 13 rotatably connected to the mounting plate 4. A connecting frame 3 is rotatably connected to the output end of the telescopic cylinder 13 via a transmission assembly. In this embodiment, the telescopic cylinder 13 is specifically a pen-shaped swing cylinder. The transmission assembly includes a mounting bracket 14 disposed at the output end of the telescopic cylinder 13. A mounting shaft 15 is mounted on the mounting bracket 14. The connecting frame 3 has a mounting hole matching the size of the mounting shaft 15, and the mounting shaft 15 is rotatably connected within the mounting hole. Therefore, activating the telescopic cylinder 13 causes the mounting bracket 14 at the output end of the telescopic cylinder 13 to extend and retract. Through the linkage principle, the connecting frame 3 rotates around the pin 8, thereby causing the connected baffle 2 to adjust its angle.

[0028] The implementation principle of this application embodiment is as follows: Activating the sliding unit drives the mounting plate 4 to slide, thereby driving the connecting frame 3 and the baffle 2 to slide synchronously, realizing the adjustment of the position of the baffle 2 in the horizontal direction; Activating the telescopic cylinder 13 drives the mounting frame 14 at the output end of the telescopic cylinder 13 to extend and retract, causing the connecting frame 3 to rotate around the pin 8, thereby driving the baffle 2 on the connecting frame 3 to rotate synchronously, realizing the adjustment of the angle of the baffle 2. The structure is compact, improves the flexibility of the position of the baffle 2, increases the control range of the wire-blocking mechanism on the wire harness, facilitates the control of the welding length and thus improves the welding effect. The position accuracy of the wire-blocking mechanism is higher and it is not easy to shake when blocking the wire.
