Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic welding, and in particular to a block pressing mechanism for an ultrasonic welding machine and an ultrasonic welding machine. Background Art

[0002] Ultrasonic metal welding technology uses the mechanical vibration energy of ultrasonic frequencies to connect the same or different metals for conductive connection. It is often used to weld thin wires or thin sheets of non-ferrous metals such as copper, silver, aluminum, and nickel. The welding process of the existing ultrasonic welding device for the wire bundle and the metal terminal is usually: first position the metal terminal, then make the two pressure blocks symmetrically arranged on the left and right sides of the metal terminal approach each other so that the two pressure blocks and the metal terminal form a U-shaped space, then the wire bundle is extended into the U-shaped space for bundling, and finally the welding head presses the wire bundle down on the metal terminal and performs wave welding; wherein the width of the U-shaped space is adjusted by adjusting the distance between the two pressure blocks, thereby controlling the width of the wire bundle. In the current ultrasonic welding device, the pressure block is driven by a cylinder to translate linearly, and the piston rod of the cylinder is parallel to the translation direction of the pressure block, and there are two pressure blocks symmetrically arranged, so the length of the device in the translation direction of the pressure block needs to be designed to be relatively large, which is not conducive to space saving and miniaturization of the device.

[0009] Furthermore, an adjusting bolt is provided on the fixing seat at a side of the first sliding groove away from the connecting block, and the adjusting bolt is threadedly connected to the fixing seat and extends into the first sliding groove to limit the stroke of the first sliding block.

[0010] An ultrasonic welding machine comprises a stand and a bottom mold mechanism, a terminal positioning mechanism, a wire clamping mechanism, a welding head mechanism and two pressing block mechanisms as described above, which are arranged on the stand, wherein the terminal positioning mechanism is located at the rear of the bottom mold mechanism in the longitudinal direction, the wire clamping mechanism is located at the front of the bottom mold mechanism in the longitudinal direction, the welding head mechanism is located above the bottom mold mechanism, and the two pressing block mechanisms are symmetrically arranged on both sides of the bottom mold mechanism in the lateral direction.

[0029] refer to Figure 4 The present application provides an ultrasonic welding machine, which is mainly used for welding a wire harness and a metal terminal. The ultrasonic welding machine includes a stand 11 and a bottom mold mechanism 12, a terminal positioning mechanism 13, a wire clamping mechanism 14, a welding head mechanism 15 and two pressing block mechanisms 16 arranged on the stand 11, wherein the terminal positioning mechanism 13 is located at the rear of the bottom mold mechanism 12 in the longitudinal direction, the wire clamping mechanism 14 is located at the front of the bottom mold mechanism 12 in the longitudinal direction, the welding head mechanism 15 is located above the bottom mold mechanism 12, and the two pressing block mechanisms 16 are symmetrically arranged on both sides of the bottom mold mechanism 12 in the transverse direction.

[0030] The terminal positioning mechanism 13 is used to position the metal terminal; the bottom mold mechanism 12 is used to support the lower surface of the welding end of the metal terminal; the two pressing block mechanisms 16 are used to make the two pressing blocks 165 approach each other, and when the two pressing blocks 165 are close to each other, they together with the upper surface of the welding end of the metal terminal form a U-shaped space, and the U-shaped space is used to bundle the wire bundle. By adjusting the distance between the two pressing blocks 165, the width of the U-shaped space can be adjusted, thereby controlling the width of the wire bundle; the wire clamping mechanism 14 is used to clamp the wire bundle after the welding end of the wire bundle extends into the U-shaped space; the welding head mechanism 15 is used to make the welding head enter the U-shaped space from the upper end of the U-shaped space and press down the wire bundle, and wave welding is performed after the wire bundle is pressed.

[0031] refer to Figures 1 to 3 In the present application, the pressing block mechanism 16 includes a fixed seat 161, a first cylinder 162, a first slider 163, a second slider 164 and a pressing block 165. The fixed seat 161 has a first slide groove 1611 opened in the longitudinal direction and a second slide groove 1612 opened in the transverse direction. The first slide groove 1611 and the second slide groove 1612 overlap in the vertical direction and are connected at the overlap through a strip hole 1613 opened in the transverse direction. The first cylinder 162 is installed on the fixed seat 161 and the piston rod is extended and retracted in the longitudinal direction. The first slider 163 is connected to the output end of the first cylinder 162 and is slidably installed on the first slide groove 1611. An inclined groove 1631 is provided on the first slider 163 along a direction inclined to the longitudinal and transverse directions. The second slider 164 is slidably installed on the second slide groove 1612. A vertical rod 1641 is provided on the second slider 164. The vertical rod 1641 passes through the strip hole 1613 and extends into the inclined groove 1631. The pressing block 165 is connected to one end of the second slider 164.

[0032] The pressing block mechanism 16 drives the first slider 163 to move longitudinally along the first slide groove 1611 through the first cylinder 162. Since the vertical rod 1641 on the second slider 164 penetrates the bar hole 1613 and extends into the inclined groove 1631 of the first slider 163, the vertical rod 1641 will be driven to move along the bar hole 1613 when the first slider 163 moves longitudinally, thereby driving the second slider 164 to move transversely along the second slide groove 1612, that is, to achieve the transverse movement of the pressing block 165. In the pressing block mechanism 16 of the present application, the stroke direction of the first cylinder 162 and the stroke direction of the pressing block 165 are perpendicular to each other, which reduces the length of the pressing block mechanism 16 compared with the previous arrangement of the stroke in the same direction. For the ultrasonic welding machine, it is provided with two symmetrically arranged pressing block mechanisms 16. By adopting the pressing block mechanism 16 of the present application, the length of the device in the transverse direction can be effectively reduced, which is conducive to space saving and miniaturization of the device.

[0033] In the ultrasonic welding machine, specifically, refer to Figure 4 The stand 11 has a lower end and an upper end opposite to the lower end, the lower end has a table top 111, the bottom mold mechanism 12, the terminal positioning mechanism 13 and the wire clamping mechanism 14 are arranged on the table top 111, the welding head mechanism 15 is arranged at the upper end of the stand 11, the pressing block mechanism 16 is installed on the stand 11 and is vertically located between the bottom mold mechanism 12 and the welding head mechanism 15, so that the pressing block mechanism 16 is suspended above the table top 111.

[0034] More specifically, see Figure 4 The stand 11 has two side panels 112, and the two side panels 112 are respectively located at the two ends of the desktop 111 in the horizontal direction. The lower end of the side panel 112 is fixedly connected to the desktop 111, and the upper end of the side panel 112 is fixedly connected to the upper end of the stand 11. The upper end of the stand 11, the desktop 111 and the two side panels 112 together form a storage space. The bottom mold mechanism 12, the terminal positioning mechanism 13, the wire clamping mechanism 14, the welding head mechanism 15 and the two pressing block mechanisms 16 are arranged in the storage space, and the two pressing block mechanisms 16 are installed on the two side panels 112 one by one.

[0035] Furthermore, a block pressing vertical driving mechanism is provided on the side plate 112, and the block pressing vertical driving mechanism includes a second cylinder and a vertical guide rail, the second cylinder and the vertical guide rail are fixedly mounted on the side plate 112, the driving end of the second cylinder is connected to the fixed seat 161 of the block pressing mechanism 16, and the fixed seat 161 of the block pressing mechanism 16 is also slidably mounted on the vertical guide rail.

[0036] During the welding process, copper wire will fall off, so the desktop 111 needs to be cleaned after a period of time. By suspending the two pressing block mechanisms 16, an empty space can be left on the desktop 111, which is convenient for cleaning the desktop 111, thereby saving space on the desktop 111 and facilitating cleaning of the desktop 111. The vertical position of the pressing block 165 can be adjusted by setting a pressing block vertical driving mechanism, and the pressing block 165 can also be ensured to press the metal terminal downward.

[0037] In the pressing mechanism 16, reference Figure 1 In this embodiment, the pressing block 165 of the pressing block mechanism 16 is L-shaped, and the upper end of the pressing block 165 is fixedly connected to the second slider 164. In this way, when the pressing block mechanism 16 is suspended above the desktop 111, the pressing block 165 can adapt to the spatial distribution.

[0038] In the block pressing mechanism 16, the first cylinder 162 is located on one side of the first slide slot 1611 in the vertical direction. Further, the second slide slot 1612 and the first cylinder 162 are located on the same side of the first slide slot 1611 in the vertical direction, so that the first cylinder 162 is arranged on one side of the second slide slot 1612 in the longitudinal direction. Figure 1 and Figure 2 In this embodiment, the first cylinder 162 and the second chute 1612 are located below the first chute 1611, and the first cylinder 162 is arranged at the rear of the second chute 1612 in the longitudinal direction. Such an arrangement can make the structure of the block pressing mechanism 16 more compact, which is conducive to the miniaturization of the ultrasonic welding machine.

[0039] In the block pressing mechanism 16, one end of the first slider 163 is located in the first slide slot 1611, and the other end extends out of the first slide slot 1611. The driving end of the first cylinder 162 is connected to the end of the first slider 163 extending out of the first slide slot 1611 through a connecting block 166. Figure 1 In this embodiment, the front end of the first slider 163 is located in the first slide groove 1611, and the rear end extends out of the first slide groove 1611. The driving end of the first cylinder 162 is at the rear in the longitudinal direction, and the rear end of the first slider 163 is connected to the driving end of the first cylinder 162 through a connecting block 166.

[0040] In the block pressing mechanism 16, an adjusting bolt 167 is provided on the fixing seat 161 at a side of the first slide slot 1611 away from the connecting block 166. The adjusting bolt 167 is threadedly connected to the fixing seat 161 and extends into the first slide slot 1611 to limit the travel of the first slider 163. Figure 1 and Figure 2In this embodiment, an adjusting bolt 167 is threadedly connected to the front of the first slider 163 on the fixing seat 161. By adjusting the length of the adjusting bolt 167 extending into the first slide slot 1611, the stroke of the first slider 163 can be adjusted, thereby limiting the lateral translation distance of the pressing block 165, and then controlling the width of the U-shaped space after the two pressing blocks 165 approach each other in the ultrasonic welding machine, thereby controlling the width of the wire harness.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
