Description

Technical Field

[0001] The invention relates to the technical field of cable harness and terminal crimping, in particular to automatic processing equipment for cable harness and terminal. Background Art

[0002] The contact surface of the wire and the terminal is strongly bonded by external force, mainly by the upper and lower blades of the crimping die and the power of the crimping machine. During crimping, the crimping ring of the terminal wraps around the bare wire, and the crimping ring is mechanically compressed to deform the metal within the specified limits, so that the stranded wire and the contact material deform symmetrically, thereby achieving good mechanical strength and electrical continuity.

[0003] However, in the existing crimping process, the cable is usually stripped manually to expose the wire part and inserted into the crimping ring of the terminal, and then placed manually on the lower supporting die of the crimping machine. The crimping machine is then turned on, and the upper crimping die presses the crimping ring on which the wire is placed. The whole process requires the cooperation of both hands, and the crimping machine needs to be turned on in the middle. Therefore, the skill level and proficiency of the operator have an important impact on the crimping quality. When new employees operate, problems such as the terminal protruding not meeting the standard and the terminal twisting and deformation may occur, which increases the defective rate of the finished product.

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 3A cable harness and terminal automatic processing equipment includes: 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 equipment, wherein the upper crimping die 12 is driven up and down by an existing hydraulic cylinder.

[0038] Continue reading Figure 1 , Figure 2 and Figure 3 An extended mounting block 2 is provided at the upper end of the horizontal section of the frame 1 and located in front of the lower supporting mold 11, and an overlap limit block 3 is provided at the upper end of the horizontal section of the frame 1 and located on the right side of the lower supporting mold 11.

[0040] See also Figure 1 , Figure 2 , Figure 4 and Fig.10 The terminal limiting mechanism 31 is arranged at the upper end of the overlap limiting block 3 and is used to limit and fix the terminal; the structure of the terminal is as follows Fig.10 As shown, it consists of a crimping ring and a connecting piece integrally welded to the crimping ring.

[0041] During the specific operation, the cable is first placed on the pre-placement mechanism 21, and correspondingly, the exposed wire of a stripped portion of the cable is placed on the wire straightening mechanism 22. At the same time, the terminal connector is placed on the overlap limit block 3 for limiting, and the crimping ring of the terminal is correspondingly placed on the lower supporting mold 11. The pushing mechanism 23 will cooperate with the pre-placement mechanism 21 and the wire straightening mechanism 22 to clamp the cable together, and then the wire at one end of the cable is straightened by the wire straightening mechanism 22. The straightened wire is pushed into the crimping ring in the terminal by the movement of the pushing mechanism 23, and then the upper crimping mold 12 is driven by the hydraulic cylinder to move in the direction of the lower supporting mold 11 for crimping.

[0042] See also Figure 1 , Figure 2 , Figure 5 and Fig. 9, a sliding groove 20 is provided on the extension mounting block 2 from front to back, and a limiting sliding groove 201 for the wire straightening mechanism 22 to slide is provided on one side of the extension mounting block 2 close to the lower supporting mold 11 and on both sides of the sliding groove 20. The pre-placement mechanism 21 includes a placement component 210 arranged on the upper end of the extension mounting block 2 through two left and right connecting frames, and the placement component 210 includes a pre-placement frame 211 fixedly connected between the two connecting frames, and an arc-shaped placement groove 212 composed of two left and right semi-arcs is provided in the middle of the pre-placement frame 211, and a pressing frame 214 is elastically connected to the upper end of the pre-placement frame 211 through a spring lifting and retracting rod 213, and a pressing groove 215 corresponding to the arc-shaped placement groove 212 is provided in the middle of the bottom end of the pressing frame 214, and the arc-shaped placement groove 212 and the pressing groove 215 are connected to form two circular structures.

[0043] Continue reading Figure 5 and Fig. 9 The wire straightening mechanism 22 includes a sliding connecting rod 221 slidably connected in the limiting slide groove 201 and a straightening component 222 connected between the two sliding connecting rods 221. The straightening component 222 has the same structure as the placement component 210, except 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 set to initially place the cable on the arc-shaped placement groove 212 of the placement component 210. A plurality of rolling balls (not shown in the figure) are rolled in the arc-shaped placement groove 212 on the placement component 210 to facilitate the movement of the cable. When the clamping 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 one end of the cable that has been stripped is placed on the arc-shaped placement groove 212 of the straightening component 222. The arc-shaped placement groove 212 and the clamping groove 215 on the straightening component 222 are fixedly bonded with rubber pads that match their shapes. Firstly, the diameters of the two circular structures formed by the arc-shaped placement groove 212 and the clamping groove 215 on the straightening component 222 are smaller than the diameters of the two circular structures formed by the arc-shaped placement groove 212 and the clamping groove 215 on the placement component 210. Secondly, the friction between the two circular structures on the straightening component 222 and the wire is increased, which facilitates the subsequent straightening of the wire.

[0045] See also Figure 5 , Fig. 9 and Fig.11 Under the action of the spring lifting and retracting rod 213, there is a certain distance between the clamping frame 214 and the pre-placement frame 211 at the beginning, which is convenient for the placement of the cables. When the clamping frame 214 moves downward, it will correspondingly compress the spring lifting and retracting rod 213, and the bottom end of the clamping frame 214 can completely fit the upper end of the pre-placement frame 211.

[0046] See also Figure 5 and Fig. 9 The straightening component 222 is slidably connected to the placement component 210 through an elastic connection mechanism 24, and the elastic connection mechanism 24 includes a top-contact round rod 241 fixedly connected to the pre-placement frame 211 on the straightening component 222 near the side of the pre-placement mechanism 21, and the top-contact round rod 241 slides through the front end of the pre-placement frame 211 on the placement component 210, and the front end of the top-contact round rod 241 is integrally formed with a top-contact round block 242, and a compression spring 243 is fixedly connected between the top-contact round block 242 and the pre-placement frame 211 on the placement component 210, and circular grooves are provided at the opposite ends of the clamping frame 214 on the placement component 210 and the clamping frame 214 on the straightening component 222, and a passive telescopic rod 244 is fixedly connected in the circular groove.

[0047] The elastic connection mechanism 24 is provided to push the wire straightening mechanism 22 to move toward the lower supporting mold 11 when the pushing mechanism 23 contacts the top contact round block 242. Under the initial force of the compression spring 243, the wire straightening mechanism 22, the pre-placement rack 211 on the placement component 210 and the pre-placement rack 211 on the straightening component 222 are in contact in the front-to-back direction, and the passive telescopic rod 244 is completely compressed in the circular groove when the front and rear clamping frames 214 are in contact. The passive telescopic rod 244 is provided so that, on the one hand, the pre-placement rack 211 and the clamping frame 214 on the straightening component 222 move synchronously when the straightening component 222 moves backward, and on the other hand, when the clamping frame 214 on the pre-placement rack 211 is pressed downward, it can drive the clamping frame 214 on the straightening component 222 to be pressed downward synchronously.

[0048] See also Figure 5 and Figure 6 The pushing mechanism 23 includes a sliding block 231 slidably connected to the sliding groove 20 through an electric slider. A receiving groove is provided at the upper end of the sliding block 231. Elastic clamping blocks 232 are fixedly connected on both sides of the receiving groove for facilitating the clamping of the cable. The elastic clamping blocks 232 are S-shaped. The elastic clamping blocks 232 on both sides are arranged in an eight-shaped shape. The distance between the two elastic clamping blocks 232 gradually decreases from the back to the front.

[0049] A matching trapezoidal block 4 is fixedly connected to one side of the clamping frame 214 on the placement component 210, and an L-shaped push rod 41 is fixedly connected to one side of the matching trapezoidal block 4 at the upper end of the sliding block 231, and a rectangular push block 42 is integrally formed on the rear side of the bottom end of the L-shaped push 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 8The terminal limiting mechanism 31 includes a stepped placement platform 311 fixedly connected to the upper end of the overlapped limiting block 3, and a side limiting block 312 is integrally formed on the right side of the stepped placement platform 311. The side limiting block 312 is a hollow frame structure, and the front and rear sides of the side limiting block 312 are provided with a through groove connected to the inside thereof, and a rubber extrusion block 313 is slidably connected in the through groove. The two rubber extrusion blocks 313 are connected by an elastic rope, and a rubber extrusion block 313 is provided on one side close to the stepped placement platform 311. An inclined surface is provided, and a rectangular matching groove 314 is provided at the upper end of the stepped placement table 311. The rectangular matching groove 314 corresponds to the position of the side limit block 312 and is connected to the inside of the side limit block 312. The inside of the side limit block 312 is connected to a matching block 315 through a spring telescopic rod, and the upper end of the matching block 315 is located in the rectangular matching groove 314 and is provided with an inclined surface; an L-shaped through hole 32 is provided on the front side of the overlap limit block 3, and the vertical section of the L-shaped through hole 32 is connected to the rectangular matching groove 314.

[0054] See also 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, and the pressing mechanism 6 includes an adaptive telescopic rod 61 fixedly connected to the bottom end of the connecting plate, and the telescopic end of the adaptive telescopic rod 61 is fixedly connected to a matching plug-in block 62, and the matching plug-in block 62 is composed of two upper and lower rectangular columns of different sizes, and a spring is fixedly connected between the matching plug-in 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 matching plug-in 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, and an L-shaped limit rod 63 is correspondingly fixedly connected to the right side of the sliding block 231, and a rectangular groove 631 is provided on the rear side of the L-shaped limit rod 63 for matching and plugging with the bottom end of the matching plug-in block 62.

[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 mold 11 until the straightened wire enters the crimping ring of the terminal. At this time, the L-shaped limit 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-in block 62 is lower than the bottom end of the upper crimping die 12. When the upper crimping die 12 synchronously drives the pressing mechanism 6 to move downward, the bottom end of the mating plug-in block 62 first enters the rectangular mating groove 314. Here, it should be noted that the elasticity of the spring between the mating plug-in block 62 and the adaptive telescopic rod 61 is much greater than the elasticity of the spring telescopic rod. The mating plug-in block 62 will push the mating block 315, and the spring telescopic rod connected to the mating block 315 will be compressed, synchronously driving the mating block 315 from the rectangular mating groove 314 into the hollow part of the side limit block 312. When the mating stopper 315 moves, it will drive the two rubber extrusion blocks 313 to move away from each other. The two rubber extrusion blocks 313 are close to the connector of the terminal, which further limits the terminal to avoid deviation during the crimping process of the terminal and the wire. The mating plug-in block 62 continues to descend until the lower part of the mating plug-in block 62 is mated with the rectangular groove 631. After the mating plug-in block 62 is plugged with the rectangular groove 631, the position of the sliding block 231 can be further stabilized to avoid the position deviation of the sliding block 231 that pushes the cable to move. When the upper crimping die 12 completes the docking of the terminal and the wire, the upper crimping die 12 moves upward, which will simultaneously unlock the sliding block 231 and the terminal connector, and take out the terminal on the terminal limiting mechanism 31 and simultaneously bring out the crimped cable.
