[0002] After leaving the factory, terminals are usually connected in a string by material strips to form connected terminals. When performing subsequent welding, the connected terminals need to be cut and then ultrasonically welded. In existing equipment, cutting and welding are completed by different processes, which makes the equipment structure complex, occupies a lot of space, and has low processing efficiency. Utility Model Content

[0003] To address the technical problems in the prior art, this utility model provides a crimping and cutting device for wire harnesses, including a base, one side of which is recessed to form a receiving space. A base felt is fixedly installed on the bottom surface of the receiving space, and a connecting terminal is installed on the base felt. The connecting terminal is slidably connected to the base felt via a feeding assembly. A welding assembly is installed on the top surface of the receiving space via a lifting cylinder. The device also includes a fixed base, which is installed on the side of the receiving space and above the welding assembly. The welding head of the welding assembly extends through the middle of the fixed base to directly above the base felt. A cylinder fixing plate is fixedly installed on the side of the fixed base away from the side. Left and right clamping mechanisms for fixing the connecting terminal are installed at both ends of the cylinder fixing plate, and the left and right clamping mechanisms are located on both sides of the welding head. A cutting cylinder is installed in the middle of the cylinder fixing plate. A cutting die mechanism is connected to the telescopic end of the cutting cylinder. The cutting die mechanism is located on the side of the welding head away from the fixed base. The cutting die mechanism moves closer to or away from the connecting terminal under the action of the cutting cylinder.

[0004] Furthermore, a sliding groove plate is installed on the cylinder fixing plate, and a vertical groove is opened in the middle of the sliding groove plate, and the die-cutting mechanism is slidably installed in the sliding groove.

[0005] Furthermore, two pressure plates are fixedly installed on the slide plate. The two pressure plates are located on both sides of the slide, and one side of the pressure plate extends into the slide. The two pressure plates and the slide form a limiting space, and the die-cutting mechanism is slidably installed in the limiting space.

[0006] Furthermore, the die-cutting mechanism includes a die-cutting fixing seat, a die, and a connecting block. The die-cutting fixing seat is engaged with the telescopic end of the cutting cylinder and is slidably installed within the limiting space. The die is fixedly connected to the bottom of the die-cutting fixing seat through the connecting block. The die moves closer to or away from the connecting terminal under the drive of the cutting cylinder.

[0007] Furthermore, the left and right clamping mechanism includes two clamping blocks arranged opposite to each other. Each clamping block includes a telescopic cylinder, an adjusting seat, and a pressing block. The telescopic cylinder is fixedly installed at the bottom of the cylinder fixing plate. The pressing block is connected to the telescopic end of the telescopic cylinder through the adjusting seat. The two pressing blocks are arranged opposite to each other.

[0009] Furthermore, two vertical linear guide rails are symmetrically installed on the side of the receiving space. The two linear guide rails are located on both sides of the welding head. The fixed base is installed on the two linear guide rails and slides towards the top surface of the receiving space under the action of the two linear guide rails.

[0010] Beneficial effects:

[0011] 1. In this utility model, the cutting of the connected terminal and the ultrasonic welding process are integrated into one unit by setting up a base felt, a feeding assembly, a welding assembly, a fixed base, a cutting cylinder, left and right clamping mechanisms, and a die-cutting mechanism. This optimizes the equipment structure, reduces the space occupancy rate, and improves processing efficiency. The specific working process is as follows: First, the feeding assembly feeds the connected terminal onto the base felt, ensuring continuous and stable feeding. Then, the left and right clamping mechanisms press down to press the terminal onto the base felt. Next, the cutting cylinder drives the die-cutting mechanism to move downwards to cut and separate the terminal from the material strip. After the material strip is cut, the cutting cylinder moves the die-cutting mechanism upwards. Finally, the lifting cylinder controls the welding assembly to weld the terminal and cable. After welding is completed, the left and right clamping mechanisms rise, and the feeding assembly feeds the next terminal from the material strip onto the base felt, repeating the above process.

[0012] 2. In this utility model, the lateral displacement of the die-cutting mechanism can be limited by the sliding plate and the sliding groove, so that it moves in a straight line in the vertical direction, ensuring the accuracy of the cutting position; combined with the setting of two pressure plates, the front and rear displacement of the die-cutting mechanism can be limited, preventing it from falling out of the sliding groove during movement or cutting, ensuring safety; the setting of the die-cutting fixing seat, die, and connecting block can facilitate the assembly and disassembly of the die, making it easy to replace and maintain.

[0013] 3. In this utility model, by setting up two clamping blocks including a telescopic cylinder, an adjusting seat, and a clamping block, the telescopic cylinder can be used to move the clamping block up and down, thereby facilitating the disassembly or fixing of the terminal; combined with the locking bolt and the setting of the clamping block slidingly connected to the adjusting seat, the distance between the two clamping blocks can be adjusted, thereby adjusting the contact area between the clamping block and the top of the terminal, improving the fixing strength, and also enabling the fixing of terminals of different widths.

[0014] 4. In this utility model, the setting of two linear guide rails makes it easy to move and fix the base, thereby increasing the distance between the base felt and the die-cutting mechanism, which facilitates the maintenance of the base felt and other structures. At the same time, it can also expose the welding components for easy maintenance. Attached Figure Description

[0029] This utility model provides a crimping and cutting device for wire harnesses, such as... Figure 1 , Figure 2 and Figure 3 As shown, the system includes a base 1, one side of which is recessed to form a receiving space 2. A base felt 3 is fixedly installed on the bottom surface of the receiving space 2. A connecting terminal 4 is installed on the base felt 3, and the connecting terminal 4 is slidably connected to the base felt 3 via a feeding assembly. A welding assembly 5 is installed on the top surface of the receiving space 2 via a lifting cylinder. The system also includes a fixed base 6, which is installed on the side of the receiving space 2 and located above the welding assembly 5. The welding head of the welding assembly 5 extends through the middle of the fixed base 6 to directly above the base felt 3. Specifically, a connecting groove is formed at the bottom middle of the fixed base 6, and the welding head horizontally passes through the connecting groove. A cylinder fixing plate 7 is fixedly installed on the side away from the side. The cylinder fixing plate 7 has left and right clamping mechanisms 8 for fixing the connecting terminal 4 at both ends. The left and right clamping mechanisms 8 are located on both sides of the welding head. A cutting cylinder 9 is installed in the middle of the cylinder fixing plate 7.

The die-cutting mechanism 10 is located on the side of the welding head away from the fixed base 6. By setting the die-cutting mechanism 10 and the welding head at intervals, interference between the two when they move up and down can be avoided. The die-cutting mechanism 10 moves closer to or away from the connecting terminal 4 under the action of the cutting cylinder 9.

[0030] In this embodiment, the cutting of the connected terminal 4 and the ultrasonic welding process can be integrated into one unit by setting up the base felt 3, feeding assembly, welding assembly 5, fixed base 6, cutting cylinder 9, left and right clamping mechanism 8 and die-cutting mechanism 10, which optimizes the equipment structure, reduces the space occupation of the equipment, and improves processing efficiency. The specific working process is as follows: First, the feeding assembly feeds the connected terminal 4 onto the base felt 3. The feeding assembly can ensure continuous and stable feeding. Then, the left and right clamping mechanism 8 presses down to press the terminal onto the base felt 3. Next, the cutting cylinder 9 drives the die-cutting mechanism 10 to move downward to cut and separate the terminal from the material strip. After the material strip is cut, the cutting cylinder 9 moves the die-cutting mechanism 10 upward. Finally, the lifting cylinder controls the welding assembly 5 to perform welding operation on the terminal and the cable. After welding is completed, the left and right clamping mechanism 8 rises, and the feeding assembly feeds the next terminal on the material strip into the base felt 3, and the above is repeated.

[0031] In this utility model, preferably, such as Figures 1 to 5 As shown, a sliding groove plate 11 is installed on the cylinder fixing plate 7. A vertical groove is opened in the middle of the sliding groove plate 11. The die-cutting mechanism 10 is slidably installed in the groove. Two pressure plates 12 are fixedly installed on the sliding groove plate 11. The two pressure plates 12 are located on both sides of the groove, and one side of the pressure plate 12 extends into the groove. The two pressure plates 12 and the groove form a limiting space. The die-cutting mechanism 10 is slidably installed in the limiting space. The die-cutting mechanism 10 includes a die-cutting fixing seat 101, a die 102, and a connecting block 103. The die-cutting fixing seat 101 is engaged with the telescopic end of the cutting cylinder 9 and is slidably installed in the limiting space. The die 102 is fixedly connected to the bottom of the die-cutting fixing seat 101 through the connecting block 103. The die 102 moves closer to or away from the connecting terminal 4 under the drive of the cutting cylinder 9.

[0032] In this embodiment, the lateral displacement of the die-cutting mechanism 10 can be limited by the sliding plate 11 and the sliding groove, so that it moves in a straight line in the vertical direction, ensuring the accuracy of the cutting position; combined with the setting of the two pressure plates 12, the front-back displacement of the die-cutting mechanism 10 can be limited to prevent it from falling out of the sliding groove during movement or cutting, ensuring safety; the die-cutting fixing seat 101, the die-cutting mold 102 and the connecting block 103 can be set up and disassembled in a convenient way, making it easy to replace and maintain.

[0033] In this utility model, preferably, such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the left and right clamping mechanism 8 includes two clamping blocks arranged opposite each other. Each clamping block includes a telescopic cylinder 81, an adjusting seat 82, and a clamping block 83. The telescopic cylinder 81 is fixedly installed on the bottom of the cylinder fixing plate 7. The clamping block 83 is connected to the telescopic end of the telescopic cylinder 81 through the adjusting seat 82. The two clamping blocks 83 are arranged opposite each other.

The bottom of the adjusting seat 82 is provided with a locking bolt 84. The clamping block 83 is slidably connected to the adjusting seat 82 and locked by the locking bolt 84. The sliding direction of the clamping block 83 and the adjusting seat 82 is closer to or farther away from the top middle of the connecting terminal 4.

[0034] In this embodiment, by setting up two clamping blocks including a telescopic cylinder 81, an adjusting seat 82, and a clamping block 83, the telescopic cylinder 81 can be used to move the clamping block 83 up and down, thereby facilitating the disassembly or fixing of the terminal; combined with the locking bolt 84 and the slidable connection between the clamping block 83 and the adjusting seat 82, the distance between the two clamping blocks 83 can be adjusted, thereby adjusting the contact area between the clamping block 83 and the top of the terminal, improving the fixing strength, and also enabling the fixing of terminals of different widths.

[0035] In this utility model, preferably, such as Figure 1 , Figure 2 and Figure 3 As shown, two vertical linear guide rails 13 are symmetrically installed on the side of the receiving space 2. The two linear guide rails 13 are located on both sides of the welding head. The fixed base 6 is installed on the two linear guide rails 13 and slides toward the top surface of the receiving space 2 under the action of the two linear guide rails 13.

[0036] In this embodiment, the two linear guide rails 13 facilitate the movement of the fixed base 6, thereby increasing the distance between the base felt 3 and the die-cutting mechanism 10, making it easier to maintain the base felt 3 and other structures. At the same time, the welding components 5 can be exposed for easy maintenance.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
