Description

Technical Field

[0001] This utility model relates to the field of terminal welding technology, and to a multi-angle terminal feeding mechanism based on wire harness welding. Background Technology

[0002] An ultrasonic terminal welding machine has an anvil and a welding head arranged opposite each other. The anvil is positioned on the welding platform. By lowering the welding head to a set position above the anvil, the terminal and the core wire can be clamped between the welding head and the anvil. Then, the ultrasonic generator emits electrical energy with a certain frequency of oscillation, which is converted into high-frequency mechanical vibration by the transducer and amplitude modulator and output from the welding head. The high-frequency vibration of the welding head is transmitted to the terminal and the core wire, so the surfaces of the terminal and the core wire rub against each other to form a fusion between the molecular layers, thereby performing welding.

[0003] A terminal feeding mechanism is required during welding. Due to space constraints, the existing feeding mechanism is relatively complex and costly. Moreover, the feeding angle is mostly fixed. When customers need to change the terminal feeding angle, the machine needs to be disassembled and adjusted again, which is time-consuming and labor-intensive. Utility Model Content

[0004] To address the technical problems in the prior art, this utility model provides a multi-angle terminal feeding mechanism based on wire harness welding, including a fixed base. A pushing component, a hopper for placing terminals, a transfer component, and an adjusting component are sequentially installed on the fixed base. The terminal slides out of the hopper and connects to the transfer component under the action of the pushing component, and is transferred to the adjusting component and connected to it under the action of the transfer component. The adjusting component includes a four-claw cylinder and a rotary cylinder. The rotary cylinder is fixedly installed on the fixed base and located at the end of the transfer component away from the hopper. The four-claw cylinder is installed on the rotary cylinder and is rotatably connected to the fixed base under the action of the rotary cylinder. The terminal is connected to the four-claw cylinder under the action of the moving component and is conveyed to the next workstation via the four-claw cylinder.

[0005] Furthermore, the fixed base includes a material pushing fixed base plate and a mechanism fixed base plate. The mechanism fixed base plate is fixedly installed on the bottom of the material pushing fixed base plate by bolts, and the two are arranged perpendicularly. The material pushing assembly and the hopper are installed on the material pushing fixed base plate, and the transfer assembly and the rotary cylinder are installed on the mechanism fixed base plate.

[0006] Furthermore, both the material pushing base plate and the mechanism base plate are provided with a plurality of positioning holes. The material pushing assembly, the hopper, the transfer assembly, and the rotary cylinder are each provided with positioning posts that match the plurality of positioning holes. The material pushing assembly, the hopper, the transfer assembly, and the rotary cylinder are all connected to the material pushing base plate and the mechanism base plate through the positioning posts and positioning holes.

[0007] Furthermore, the pushing assembly includes a pushing cylinder and a material push rod. The pushing cylinder is fixedly installed at one end of the fixed base, and the telescopic end of the pushing cylinder is fixedly connected to the material push rod. The end of the material push rod away from the pushing cylinder is slidably installed at the discharge port of the hopper. The terminal slides out of the discharge port and connects to the transfer assembly under the drive of the material push rod.

[0008] Furthermore, the transfer assembly includes a gripper cylinder and a rodless cylinder. The rodless cylinder is fixedly mounted on a fixed base and located between the hopper and the rotary cylinder. The gripper cylinder is fixedly mounted on the piston of the rodless cylinder. The gripper cylinder is connected to the discharge port or the four gripper cylinders.

[0009] Furthermore, a proximity sensor is installed on the hopper to monitor the number of terminals.

[0010] Beneficial effects: 1. This utility model, through the arrangement of a pushing component, a hopper for placing terminals, a transfer component, and an adjustment component, facilitates continuous terminal feeding during welding. It features a simple structure and low cost. Combined with a 4-jaw cylinder and a rotary cylinder, the rotary cylinder drives the 4-jaw cylinder to rotate, thereby adjusting the terminal feeding angle to meet different customer needs for feeding angles. It requires no disassembly and occupies little space. The working process is as follows: the pushing cylinder drives the material push rod, sequentially feeding the terminals from the hopper. After the terminals are in place, they are clamped by the jaw cylinder and transported to the holding plate on the 4-jaw cylinder by the rodless cylinder. The 4-jaw cylinder is then driven to perform secondary positioning and correction of the terminals, awaiting the next workstation for welding. If the customer needs to adjust the terminal feeding angle due to placement space or other factors, such as requiring a 90-degree feeding angle, the rotary cylinder is then driven to rotate the 4-jaw cylinder by 90 degrees.

[0011] 2. In this utility model, the arrangement of the material feeding mechanism with a fixed base plate for pushing and a fixed base plate for the mechanism and the vertical connection between the two can make the structure of the feeding mechanism compact and further reduce its space occupation; the arrangement of positioning holes and positioning columns can facilitate the quick installation of the material feeding component, hopper, transfer component and rotary cylinder, thereby improving installation efficiency.

[0012] 3. In this utility model, the proximity sensor enables real-time monitoring of the number of terminals, avoiding insufficient terminal quantity and ensuring the continuous and stable operation of the feeding mechanism. Attached Figure Description

[0022] This utility model provides a multi-angle terminal feeding mechanism based on wire harness welding, such as Figure 1 and Figure 2As shown, the device includes a fixed base 1, on which a pushing assembly 2, a hopper 3 for placing terminals, a transfer assembly 4, and an adjusting assembly 5 are sequentially mounted. The terminals slide out of the hopper 3 and connect to the transfer assembly 4 under the action of the pushing assembly 2, and are transferred to the adjusting assembly 5 and connected to it. The pushing assembly 2 includes a pushing cylinder 21 and a material push rod 22. The pushing cylinder 21 is fixedly installed at one end of the fixed base 1, and its telescopic end is fixedly connected to the material push rod 22. The end of the material push rod 22 away from the pushing cylinder 21 is slidably installed at the outlet of the hopper 3. The terminals slide out of the outlet and connect to the transfer assembly 4 under the action of the material push rod 22. The adjusting assembly 5 includes four clamps. The transfer assembly 4 includes a gripper cylinder 51 and a rotary cylinder 52. The rotary cylinder 52 is fixedly mounted on the fixed base 1 and located at the end of the transfer assembly 4 away from the hopper 3. The four-grip gripper cylinder 51 is mounted on the rotary cylinder 52 and is rotatably connected to the fixed base 1 under the action of the rotary cylinder 52. The transfer assembly 4 includes a gripper cylinder 41 and a rodless cylinder 42. The rodless cylinder 42 is fixedly mounted on the fixed base 1 and located between the hopper 3 and the rotary cylinder 52. The gripper cylinder 41 is fixedly mounted on the piston of the rodless cylinder 42. The gripper cylinder 41 is connected to the discharge port or the four-grip gripper cylinder 51. The terminal is transferred from the discharge port to the four-grip gripper cylinder 51 under the drive of the gripper cylinder 41 and is conveyed to the next station through the four-grip gripper cylinder 51.

[0023] In this embodiment, the arrangement of the pusher assembly 2, the hopper 3 for placing terminals, the transfer assembly 4, and the adjustment assembly 5 facilitates continuous feeding of terminals during welding. The structure is simple and the cost is low. Combined with the arrangement of the four-claw cylinder 51 and the rotary cylinder 52, the rotary cylinder 52 can drive the four-claw cylinder 51 to rotate, thereby adjusting the angle of terminal feeding to meet the needs of customers for different feeding angles. It does not require disassembly and occupies little space.

[0024] like Figure 1 and Figure 2 As shown, the working process is as follows: the pusher cylinder 21 drives the material pusher 22 to sequentially send out the terminals from the hopper 3. After the terminals are in place, they are clamped by the gripper cylinder 41 and transported to the holding plate on the four-grip cylinder 51 by the rodless cylinder 42. The four-grip cylinder 51 is then driven to perform secondary positioning and correction of the terminals, ready for the next station, i.e., welding. If the customer needs to adjust the terminal feeding angle due to placement space or other factors, such as requiring 90-degree feeding, the rotary cylinder 52 is then driven to rotate the four-grip cylinder 51 by 90 degrees.

[0025] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the fixed base 1 includes a pusher fixing base plate 11 and a mechanism fixing base plate 12. The mechanism fixing base plate 12 is fixedly installed on the bottom of the pusher fixing base plate 11 by bolts, and the two are arranged perpendicularly. The pusher assembly 2 and the hopper 3 are installed on the pusher fixing base plate 11, and the transfer assembly 4 and the rotary cylinder 52 are installed on the mechanism fixing base plate 12. Both the pusher fixing base plate 11 and the mechanism fixing base plate 12 are provided with a plurality of positioning holes. The pusher assembly 2, the hopper 3, the transfer assembly 4 and the rotary cylinder 52 are provided with positioning posts that match the plurality of positioning holes. The pusher assembly 2, the hopper 3, the transfer assembly 4 and the rotary cylinder 52 are all connected to the pusher fixing base plate 11 and the mechanism fixing base plate 12 through the positioning posts and positioning holes.

[0026] In this embodiment, the arrangement of the material feeding mechanism with the material feeding base plate 11, the mechanism fixing base plate 12 and the vertical connection between the two can make the structure of the feeding mechanism compact and further reduce its space occupation; the arrangement of the positioning holes and positioning columns can facilitate the quick installation of the material feeding component 2, the hopper 3, the transfer component 4 and the rotary cylinder 52, thereby improving the installation efficiency.

[0027] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, a proximity sensor 6 is installed on the hopper 3, and the proximity sensor 6 is used to monitor the number of terminals.

[0028] In this embodiment, the proximity sensor 6 enables real-time monitoring of the number of terminals, preventing insufficient terminal quantity and ensuring the continuous and stable operation of the feeding mechanism.

[0029] 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.

[0030] 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.
