Description

Technical Field

[0001] The present invention relates to the technical field of crimping of cable harnesses and terminals, and specifically to an automatic processing device for cable harnesses and terminals. Background Art

[0002] By applying external force, the contact surface between the wire and the terminal is strongly combined, mainly by relying on the upper and lower blades of the crimping die and the force of the crimping machine. During crimping, the crimping ring of the terminal wraps the bare wire, and the crimping ring is mechanically pressed to cause the metal to deform within a specified limit, enabling the stranded wire and the contact material to deform symmetrically, thereby achieving good mechanical strength and electrical continuity.

[0003] However, in the existing crimping process, generally, the part of the wire exposed by manually stripping the cable is inserted into the crimping ring of the terminal by hand, and then directly placed on the lower supporting die of the crimping machine by hand. Then, the crimping machine is started, and the upper crimping die presses the crimping ring where the wire is placed. The entire process requires the cooperation of both hands and the crimping machine needs to be started midway. Therefore, the skill level and operation proficiency of the operator have an important impact on the crimping quality. When new employees operate, problems such as the terminal head not meeting the standard and the terminal being distorted and deformed may occur, increasing the defective rate of the finished product.

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0037] See also Figure 1 , Figure 2 and Figure 3, a cable harness and terminal automatic processing device, comprising: a frame 1, a lower supporting die 11 fixedly connected to the upper end of the horizontal section of the frame 1, and an upper crimping die 12 slidably connected to the vertical section of the frame 1; the lower supporting die 11 and the upper crimping die 12 are existing crimping devices, wherein the upper crimping die 12 is driven to move up and down by an existing hydraulic cylinder.

[0038] Continue to refer to Figure 1 , Figure 2 and Figure 3 , an extension mounting block 2 is provided at the upper end of the horizontal section of the frame 1 and on the front side of the lower supporting die 11, and a lapping limit block 3 is provided at the upper end of the horizontal section of the frame 1 and on the right side of the lower supporting die 11.

[0039] A pre-placement mechanism 21 is provided at the upper end of the extension mounting block 2 and close to the direction of the lower supporting die 11 for placing the cable; a wire straightening mechanism 22 for pressing and straightening the wire is slidably provided at the rear side of the pre-placement mechanism 21; a pushing mechanism 23 is provided on the front side of the pre-placement mechanism 21 and slidably on the extension mounting block 2, and a protective cover (as Figure 1 shown) is commonly provided above the wire straightening mechanism 22 and the pushing mechanism 23, and the protective cover is fixedly connected to the upper end of the horizontal section of the frame 1. The protective cover is made of transparent plastic products for convenient observation of the internal operation.

[0040] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 10 , a terminal limiting mechanism 31 is provided at the upper end of the lapping limit block 3 for limiting and fixing the terminal; the structure of the terminal is as Figure 10 shown, and it is composed of a crimping ring and a connecting piece integrally welded on the crimping ring.

[0041] During specific operation, first place the cable on the pre-placement mechanism 21. Correspondingly, the wire with the peeled part of one end of the cable is placed on the wire straightening mechanism 22. At the same time, place the connecting piece of the terminal on the lapping limit block 3 for limiting, and place the crimping ring of the terminal correspondingly on the lower supporting die 11. The pushing mechanism 23 will cooperate with the pre-placement mechanism 21 and the wire straightening mechanism 22 to clamp the cable together. Then, straighten the wire at one end of the cable through the wire straightening mechanism 22. The straightened wire is pushed into the crimping ring inside the terminal by the movement of the pushing mechanism 23. Then, drive the upper crimping die 12 to move towards the lower supporting die 11 through the hydraulic cylinder for crimping.

[0042] Refer to Figure 1 , Figure 2 , Figure 5 and Figure 9, a sliding groove 20 is formed in the extending mounting block 2 from front to back. On one side of the extending mounting block 2 close to the lower supporting die 11 and on both sides of the sliding groove 20, limiting sliding grooves 201 for the sliding of the wire straightening mechanism 22 are formed. The pre-placement mechanism 21 includes a placement component 210 arranged at the upper end of the extending mounting block 2 through two left and right connecting frames. The placement component 210 includes a pre-placement frame 211 fixedly connected between the two connecting frames. An arc-shaped placement groove 212 composed of two left and right semi-arcs is formed in the middle of the pre-placement frame 211. The upper end of the pre-placement frame 211 is elastically connected with a pressing frame 214 through a spring telescopic rod 213. A pressing groove 215 corresponding to the arc-shaped placement groove 212 is formed in the middle of the bottom end of the pressing frame 214. The arc-shaped placement groove 212 and the pressing groove 215 are butted to form two circular structures.

[0043] Continue to refer to Figure 5 and Figure 9 , the wire straightening mechanism 22 includes a sliding connecting rod 221 slidably connected in the limiting sliding groove 201 and a straightening component 222 commonly connected between the two sliding connecting rods 221. The straightening component 222 has the same structure as the placement component 210. The difference is that the lengths of the pre-placement frame 211 and the pressing frame 214 on the placement component 210 are both greater than the lengths of the pre-placement frame 211 and the pressing frame 214 on the straightening component 222.

[0044] The placement component 210 is provided to initially place the cable on the arc-shaped placement groove 212 of the placement component 210. A plurality of balls (not shown in the figure) for facilitating the movement of the cable are rotatably arranged in the arc-shaped placement groove 212 of the placement component 210. When the pressing frame 214 at the upper end of the placement component 210 is not clamped, it is convenient to push the cable to move. Correspondingly, the exposed wire at the peeled end of the cable is placed on the arc-shaped placement groove 212 of the straightening component 222. Rubber pads matching their shapes are fixedly bonded in both the arc-shaped placement groove 212 and the pressing groove 215 of the straightening component 222. First, the diameters of the two circular structures formed by the arc-shaped placement groove 212 and the pressing groove 215 on the straightening component 222 are both smaller than the diameters of the two circular structures formed by the arc-shaped placement groove 212 and the pressing groove 215 on the placement component 210. Second, the friction between the two circular structures on the straightening component 222 and the wire is increased, which is convenient for subsequent wire straightening operations.

[0045] Refer to Figure 5 , Figure 9 and Figure 11 , under the action of the spring telescopic rod 213, there is a certain distance between the pressing frame 214 and the pre-placement frame 211 initially, which is convenient for the placement of the cable. When the pressing frame 214 moves downward, the spring telescopic rod 213 will be correspondingly compressed, and the bottom end of the pressing frame 214 can completely fit the upper end of the pre-placement frame 211.

[0046] Refer to Figure 5 and Figure 9

[0046]

[0047] The elastic connection mechanism 24 is provided to enable the wire straightening mechanism 22 to move towards the lower supporting die 11 when the pushing mechanism 23 contacts the top contact round block 242. Under the initial acting force of the compression spring 243, the pre-placement frame 211 on the placement component 210 and the pre-placement frame 211 on the wire straightening component 222 are in contact in the front-rear direction. When the two pressing frames 214 are in contact, the passive telescopic rod 244 is completely compressed in the circular groove. The passive telescopic rod 244 is provided for two purposes. On the one hand, when the wire straightening component 222 moves backward, the pre-placement frame 211 and the pressing frame 214 on the wire straightening component 222 move synchronously. On the other hand, when the pressing frame 214 on the pre-placement frame 211 presses downward, it can drive the pressing frame 214 on the wire straightening component 222 to press downward synchronously.

[0048] Refer to Figure 5 and Figure 6

[0046]

[0049] One side of the pressing frame 214 on the placement component 210 is fixedly connected with a mating trapezoidal block 4. On the upper end of the sliding block 231, an L-shaped pushing rod 41 is fixedly connected corresponding to one side of the mating trapezoidal block 4. A rectangular pushing block 42 is integrally formed at the rear side of the bottom end of the L-shaped pushing rod 41.

[0050] Start the electric slider to drive the sliding block 231 to move backward, and the cable will gradually enter between the elastic clamping blocks 232. The elastic clamping blocks 232 are placed in an eight-shape to facilitate the entry of the cables. In the process of moving the sliding block 231, the L-shaped push rod 41 is synchronously driven to move. The front side of the matching trapezoidal block 4 is provided with a slope, and the rectangular push block 42 will gradually cooperate with the matching trapezoidal block 4. During the contact between the rectangular push block 42 and the matching trapezoidal block 4, the clamping frame 214 will be driven to move downward until the bottom end of the rectangular push block 42 contacts the top end of the matching trapezoidal block 4. At this time, the clamping frame 214 is in contact with the pre-placement frame 211.

[0051] Continue reading Figure 5 and Figure 6 , the sliding block 231 is provided with a through hole 51 at the position corresponding to the top contact round rod 241 from front to back, and the left and right sides of the sliding block 231 are provided with a clearance groove 52 near the rear end, the clearance groove 52 is connected with the through hole 51, the top of the clearance groove 52 passes through the top of the sliding block 231, and a connecting limit groove 53 is provided between the two clearance grooves 52, and baffle plates 54 are arranged in the clearance grooves 52 to slide up and down, the vertical section of the baffle plates 54 is located at the position of the through hole 51, and the horizontal section of the baffle plates 54 extends to the side of the sliding block 231, and a connecting rod 55 is fixedly connected in the middle of the two baffle plates 54, and the connecting rod 55 slides up and down in the connecting limit groove 53; correspondingly, a lifting block 56 is fixedly connected to the front side of the pre-placement rack 211 in the placement component 210, and the upper end of the lifting block 56 is inclined near the front side.

[0052] When the sliding block 231 slides a certain distance in the sliding groove 20, the top contact round block 242 will contact the baffle plate 54, and the baffle plate 54 follows the sliding of the sliding block 231 to push the top contact round block 242. In the process of the baffle plate 54 pushing the top contact round block 242, the bottom end of the rectangular pushing block 42 is always in contact with the matching trapezoidal block 4, and the clamping frame 214 on the pushing mechanism 23 is in a fit with the pre-placement frame 211 to straighten the wire. When the top contact round rod 241 drives the wire straightening mechanism 22 to completely detach from the wire, the straightening operation is completed. At this time, the bottom end of the rectangular pushing block 42 is no longer in contact with the matching trapezoidal block 4, and the clamping frame 214 will return to its original position under the action of the spring lifting and retracting rod 213, and the clamping frame 214 no longer clamps the cable and the wire.

[0053] See also Figure 2 , Figure 4 , Figure 7 and Figure 8, the terminal limiting mechanism 31 includes a stepped placement table 311 fixedly connected to the upper end of the overlapping limiting block 3. A side limiting block 312 is integrally formed on the right side of the stepped placement table 311. The side limiting block 312 is a hollow frame structure. Through grooves communicating with its interior are formed on the front and rear sides of the side limiting block 312. Rubber extrusion blocks 313 are slidably connected in the through grooves. The two rubber extrusion blocks 313 are connected by an elastic cord. An inclined surface is provided on one side of the rubber extrusion block 313 close to the stepped placement table 311. A rectangular fitting groove 314 is formed at the upper end of the stepped placement table 311. The position of the rectangular fitting groove 314 corresponding to the side limiting block 312 is communicated with the interior of the side limiting block 312. A fitting stop block 315 is connected to the interior of the side limiting block 312 by a spring telescopic rod. The upper end of the fitting stop block 315 located in the rectangular fitting groove 314 is provided with an inclined surface; an L-shaped through hole 32 is formed on the front side of the overlapping limiting block 3. The vertical section of the L-shaped through hole 32 is communicated with the rectangular fitting groove 314.

[0054] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , a pressing mechanism 6 is provided on the right side of the upper crimping die 12 through a connecting plate. The pressing mechanism 6 includes an adaptive telescopic rod 61 fixedly connected to the bottom end of the connecting plate. The telescopic end of the adaptive telescopic rod 61 is fixedly connected with a fitting insertion block 62. The fitting insertion block 62 is composed of two rectangular columns of different sizes up and down. A spring is fixedly connected between the fitting insertion block 62 and the bottom end of the fixed end of the adaptive telescopic rod 61; it should be noted here that the initial distance between the fitting insertion block 62 and the stepped placement table 311 is greater than the height of the terminal, which is convenient for loading and unloading the terminal. An L-shaped limiting rod 63 is fixedly connected to the right side corresponding to the sliding block 231. A rectangular groove 631 for fitting and inserting the bottom end of the fitting insertion block 62 is formed on the rear side of the L-shaped limiting rod 63.

[0055] When the pre-placement mechanism 21 no longer clamps and limits the cable, the sliding block 231 continues to move to the right, which will drive the cable to continue to move in the direction of the lower supporting die 11 until the straightened wire enters the crimping circle of the terminal. At this time, the L-shaped limiting rod 63 enters the L-shaped through hole 32 and abuts against the side wall of the horizontal section of the L-shaped through hole 32.

[0056] The bottom end of the mating plug block 62 is lower than the bottom end of the upper crimping die 12. When the upper crimping die 12 drives the pressing mechanism 6 to move downward synchronously, the bottom end of the mating plug block 62 first enters the rectangular mating groove 314. Here, it should be noted that the elasticity of the spring between the mating plug block 62 and the adaptive telescopic rod 61 is much greater than that of the spring telescopic rod. The mating plug block 62 will push the mating stop block 315, and the spring telescopic rod connecting the mating stop block 315 will be compressed, synchronously driving the mating stop block 315 to enter the hollow part of the side limit block 312 from the rectangular mating groove 314. During the movement of the mating stop block 315, it will drive the two rubber extrusion blocks 313 to move away from each other. The side of the two rubber extrusion blocks 313 away from each other is closely attached to the connecting part of the terminal, further limiting the terminal to prevent the terminal and the wire from shifting during the crimping process. When the mating plug block 62 continues to descend until the lower part of the mating plug block 62 is inserted into the rectangular groove 631, after the mating plug block 62 is inserted into the rectangular groove 631, it can further stabilize the position of the sliding block 231 and prevent the sliding block 231 that pushes the cable from shifting. When the upper crimping die 12 completes the docking of the terminal and the wire, the upper crimping die 12 moves upward, which will synchronously unlock the sliding block 231 and the terminal connecting part, and take out the terminal from the terminal limiting mechanism 31 and synchronously bring out the crimped cable.
