Description

Technical Field

[0001] This utility model relates to the field of terminal crimping mold technology, specifically to a feeding mechanism for an easily adjustable terminal crimping mold. Background Technology

[0002] Automotive terminals are used to connect fuses, battery terminals, and vehicle sensors. They are widely used in cars, trucks, motorcycles, RVs, off-road vehicles, engineering vehicles, and electric vehicles. Automotive terminals are connectors that connect automotive electrical systems, also known as automotive cable connectors or automotive wiring harness connectors. They are usually made of metal and can connect wires and cables for transmitting power, signals, and data. There are many different types of automotive terminals, each suitable for different application scenarios, including low voltage, high current, high temperature, and low temperature.

[0003] Chinese patent publication number "CN216214740U" discloses "A feeding mechanism for an automotive wiring harness terminal crimping mold, specifically relating to the field of mechanical technology." The mechanism includes a crimping mold fixing frame, an internal lifting groove, and feeding plates fixedly mounted on both sides of the frame. Each feeding plate has a feeding slide groove communicating with the lifting groove. Feeding ropes are threaded through both the feeding slide groove and the lifting groove. A wiring harness terminal body is connected to the surface of the feeding rope. A fixing frame is fixedly mounted on the top of the feeding plate, and the fixing frame contains... The patented "winding mechanism" uses a motor to drive a winding roller to wind the feeding rope onto the winding roller, thereby moving the feeding rope within the feeding groove in the feeding plate. This allows the wire harness terminal body on the feeding rope to be moved to the designated area to complete the feeding. The rotating roller changes the direction of movement of the feeding rope, so the winding process of the winding roller is relatively smooth. However, the feeding mechanism of the above patent lacks adjustment function. When feeding different types of terminals, it cannot quickly adjust the feeding requirements, resulting in a mediocre performance of the device. Therefore, we propose a feeding mechanism for terminal crimping molds that is easy to adjust. Utility Model Content

The end of the second connecting rod 150 is fixedly connected to the middle of the rear side wall of the guide frame 300. A convex pressing mold 160 is fixedly connected to the bottom of the inner cavity of the frame 100. A cylinder 170 is fixedly connected to the top of the frame 100. A concave pressing mold 171 is fixedly connected to the output end of the cylinder 170. Left sliding openings are provided on the upper and lower sides of the left side wall of the frame 100. The inner cavity of the left sliding groove 180 is slidably connected to the left slider 181, which is fixedly connected to the upper and lower sides of the right side wall of the mounting box 200. The upper and lower sides of the right side wall of the frame 100 are provided with right sliding grooves 190, and the inner cavity of the right sliding groove 190 is slidably connected to the right slider 191, which is fixedly connected to the upper and lower sides of the left side wall of the guide frame 300. The first motor 110 drives the screw 120 to rotate, which in turn drives the moving plate 130 to move. The moving plate 130 then drives the first connecting rod 140 and the second connecting rod 150 to move, which in turn drives the mounting box 200 and the guide frame 300 to move horizontally. Finally, by adjusting the positions of the mounting box 200 and the guide frame 300, the device can always ensure that the terminals are aligned with the crimping mold when feeding terminals of different lengths.

[0032] In summary, this makes the feeding mechanism easier to adjust and improves the feeding efficiency of the device.

[0033] Please see Figure 1-4The mounting box 200 is slidably connected to the left side wall of the frame 100, and the guide frame 300 is slidably connected to the right side wall of the frame 100. Fixing plates 210 are fixedly connected to the front and rear sides of the top of the inner cavity of the mounting box 200. A second motor 220 is fixedly connected to the inner side wall of the fixing plate 210. A take-up roller 230 is fixedly connected to the end of the power output shaft of the second motor 220. A feeding rope 240 is wound around the outer side wall of the take-up roller 230. A guide roller 250 is rotatably connected between the front and rear side walls of the inner cavity of the mounting box 200. A first electric push rod 310 is fixedly connected to the top of the inner cavity of the guide frame 300. An upper guide plate 320 is fixedly connected to the end of the first electric push rod 310. A second electric push rod 330 is fixedly connected to the middle of the bottom of the guide frame 300. The lower guide plate 340 is fixedly connected to the end of 330. Guide rods 350 are fixedly connected to the bottom left and right sides of the lower guide plate 340. The end of the guide rod 350 passes through the guide frame 300 and extends to the bottom of the guide frame 300. The end of the guide rod 350 is fixedly connected to the second limiting block 360. The lower guide plate 340 is raised and lowered by the second electric push rod 330 to adjust the position of the lower guide plate 340. Then, the upper guide plate 320 is moved vertically by the first electric push rod 310 to adjust the height of the upper guide plate 320. Finally, by adjusting the positions of the lower guide plate 340 and the upper guide plate 320, the lower guide plate 340 and the upper guide plate 320 can guide terminals of different specifications, thereby improving the stability of terminal feeding.

[0034] In summary, this enables the device to guide terminals of different specifications.

[0035] In practical use, those skilled in the art first connect the feeding rope 240 to the terminal. Then, the second electric actuator 330 drives the lower guide plate 340 to rise and fall, adjusting its position. Next, the first electric actuator 310 drives the upper guide plate 320 to move vertically, adjusting its height. The distance between the lower and upper guide plates 340 should be slightly wider than the terminal. Then, the first motor 110 drives the screw 120 to rotate, causing the screw 120 to move the moving plate 130. The moving plate 130 then moves the first connecting rod 140 and the second connecting rod 150, causing the first connecting rod 140 and the second connecting rod 150 to move respectively. The mounting box 200 and the guide frame 300 move horizontally. By adjusting the positions of the mounting box 200 and the guide frame 300, the horizontal crimping position of the terminal is aligned with the convex crimping mold 160. Then, the second motor 220 drives the take-up roller 230 to rotate, causing the feeding rope 240 to pull the terminal to the left. At this time, the terminal is pulled between the lower guide plate 340 and the upper guide plate 320, so that the lower guide plate 340 cooperates with the upper guide plate 320 to guide the terminal, thereby avoiding large swings when the terminal is fed. Finally, the terminal is pulled into the convex crimping mold 160, and the cylinder 170 is activated to drive the concave crimping mold 171 to descend, so that the concave crimping mold 171 cooperates with the convex crimping mold 160 to crimp the terminal.
