Description

Technical Field

[0001] This invention relates to the field of wire harness or cable processing, and more specifically to a hydraulic cable processing system. Background Technology

[0002] Wire harnesses, cables, and wire wires are commonly used components in existing technologies. During their widespread application, there is a need for docking or connecting with other equipment. When connecting, terminals are required to achieve docking. Therefore, wire harnesses need to be processed. The processing includes winding, feeding, straightening, cutting, stripping, crimping, and terminal feeding, among other processes.

[0003] In practical engineering work, the following problems exist:

[0004] In existing wire harness processing technology, not only is wire feeding required, but also terminal feeding is necessary before the wire harness and terminals can be connected, and only after connection can crimping be applied. The terminal feeding process requires a drive structure to propel the terminals forward; multiple terminals are fed in a strip, then cut and crimped one by one. However, common belt conveyors often use drive rollers and driven rollers to achieve the conveyor belt transport. During the terminal belt transport process, continuous cutting is required, which makes conventional belt conveyor methods unsuitable.

[0005] Second, existing technologies also include methods to drive the conveying feed other than roller conveying, but the driving source for this feed is generally hydraulic or pneumatic. However, the accuracy of hydraulic or pneumatic feed is difficult to control. Even if high-precision feed can be achieved, it requires multiple components such as sensors, controllers, and communicators, which results in high costs.

[0006] Third, the trajectory control problem in existing technologies involving cyclic feed is a significant issue.

[0007] Fourth, existing circular rotation structures experience significant trajectory interference during rotation.

[0008] Fifth, existing circular rotation structures lack effective control over trajectory changes.

[0009] VI. Existing push-feed technology is limited to pushing a single object. Terminal conveyor belts include multiple terminals and are soft, making it difficult to effectively push the entire soft belt.

[0010] 7. Existing push rods are of poor quality and have a short lifespan.

[0011] 8. In the existing technology, during the push rod pushing process, there may be unexpected return such as motor reversal, which will cause unexpected movement or damage to the conveyor belt. Summary of the Invention

[0012] To overcome the above problems, the present invention proposes a solution that addresses multiple problems simultaneously.

[0013] The technical solution adopted by this invention to solve its technical problem is: a hydraulically controlled cable processing system, including a terminal strip, a wire harness, a cutting device, a wire stripping device, a terminal conveying device, a crimping device, and a hydraulic control system; the wire stripping device strips the insulation from the end of the wire harness, the cutting device cuts the wire harness, and the stripped end of the cut wire harness is inserted into a terminal and then crimped by the crimping device; the driving structure of the wire stripping device includes an upper stripping cylinder and a lower stripping cylinder, the driving structure of the cutting device includes a cutting cylinder, and the driving structure of the crimping device includes a crimping cylinder; the hydraulic control system includes an oil tank, a filter, an oil pump, a check valve, a first reversing valve, a second reversing valve, a third reversing valve, an accumulator, a pressure gauge, and a throttle valve; the oil pump and A filter is connected between the oil tanks. The output end of the oil pump is connected to the first to third oil circuits. In the first oil circuit, the oil circuit is connected to both ends of the crimping cylinder after passing through the first check valve and the first reversing valve. A pressure gauge is connected between the lower pressing end of the crimping cylinder and the first reversing valve, and an accumulator is connected between the lifting end of the crimping cylinder and the first reversing valve. In the second oil circuit, the oil circuit is connected to the first branch and the second branch in parallel after passing through the second check valve and the second reversing valve. The first branch is connected to one end of the upper peeling cylinder and the lower peeling cylinder, and the second branch is connected to the other end of the upper peeling cylinder and the lower peeling cylinder, respectively. In the third oil circuit, the oil circuit is connected to both ends of the cut-off cylinder after passing through the third check valve and the third reversing valve. A throttle valve is connected between the cut-off cylinder and the third reversing valve.

[0014] The terminal strip includes terminals and a connecting strip. Multiple terminals are arranged on the connecting strip with gaps between them. The terminal conveying device includes a motor, an output shaft, a cylinder, a telescopic rod, a main rod, a push rod, an adapter block, a cylinder, a piston plate, a spring, a track, a first bracket, a stop block, a second bracket, an arm, a connecting pipe, and a stop bar. The connecting strip can move along the track. The output shaft of the motor extends upward. The cylinder is vertically connected to the upper end of the output shaft. The telescopic rod can extend and retract within the cylinder. A piston plate is provided at one end of the telescopic rod, and a spring is provided between the piston plate and the inner wall of the cylinder. The other end of the telescopic rod is pivotally connected to the main rod below and to the cylinder above. The push rod is provided below the main rod, and the adapter block is provided below the push rod. The adapter block includes an inclined surface.

[0015] The first and second supports are located on both sides of the terminal strip. The first support is provided with the stop block, which includes an arc surface. The upper end of the second support is provided with the arm, and the front end of the arm is provided with a connecting tube. The connecting tube is a square tube, excluding the lower wall. The side wall of the connecting tube is provided with an opening, and the side of the opening is pivotally connected to the stop rod. The stop rod can rotate inward into the connecting tube but cannot rotate outward. The connecting tube and the stop block are staggered vertically.

[0016] In the pushing position, the adapter block is inserted into the gap to push the terminal strip to move. As the motor drives the rotation, the telescopic rod abuts against and is squeezed by the arc surface. When the telescopic rod moves to the end of the arc surface, the cylinder pushes away the stop bar and enters the connecting tube. Subsequently, the motor rotates in the opposite direction, the cylinder moves in the connecting tube while the telescopic rod returns to its original position. After the telescopic rod returns to its original position, driven by the spring force, the telescopic rod drives the cylinder to disengage from the through hole on the connecting tube and extend forward so that the adapter block can enter the next gap.

[0017] Preferably, a groove is provided on the arm at the position where it connects to the connecting pipe.

[0018] Preferably, the groove is in communication with the connecting pipe.

[0019] Preferably, the cylinder can enter the groove to reserve space for the return of the stop bar.

[0020] Preferably, the adapter block includes a pushing surface.

[0021] Preferably, the pushing surface includes a plane and an arc surface.

[0022] Preferably, the diameter of the main rod is larger than the diameter of the push rod.

[0023] Preferably, the left end of the connecting pipe is open.

[0024] Preferably, the through hole is a square hole.

[0025] Preferably, the through hole and the opening are located on the same wall surface of the connecting pipe.

[0026] The beneficial effects of this invention are:

[0027] Firstly, regarding the first point raised in the background technology, the terminal conveyor belt is pushed by pushing and returning the push rod, thus solving the problem of belt conveyor being cut off.

[0028] Second, regarding the second point raised in the background technology, the movement of the push rod is achieved by a motor, and the approach or disengagement from the terminal strip is achieved by a telescopic rod. Therefore, a large number of sensors, controllers, and communicators can be replaced by a motor alone.

[0029] Thirdly, in response to the third point raised in the background technology, two rotational trajectories were constructed. During the pushing process, the position control of the push feed was completed by the cooperation of the telescopic rod and the arc surface. During the return process, the return track was used to make the push rod avoid the material and return to its original position, so as to avoid the collision between the push rod and the material affecting the position of the material or damaging the material.

[0030] Fourthly, in response to the fourth point raised in the background technology, a cylindrical head is set on the push rod module to cooperate with the return track. With the help of the telescopic rod and the arc surface, the arc surface and the return track are staggered vertically, and the positions of the cylinder and the telescopic rod are also different, thus constructing two tracks that each perform their own functions.

[0031] Fifth, regarding the fifth point raised in the background technology, a one-way stop is set at the intersection of the feed and return tracks. After the cylinder pushes open the one-way stop and enters the return track, it is blocked by the one-way stop and cannot return to its original position. At the same time, a groove is set on the return arm to reserve more space so that the cylinder can pull away from the stop, so that the one-way stop has enough space to return to its original position.

[0032] VI. Regarding points 6 and 7 in the background art, a push rod is set at the lower end of the main rod, and an adapter block is set at the lower end of the push rod to adapt to the gap between two terminals in the terminal strip. The inclined surface of the adapter block is inserted into the gap, and the plane of the adapter block pushes the terminal strip forward. The large size of the main rod increases the structural strength of the push module, and the push rod and the adapter block below adapt to the size of the gap.

[0033] VII. Regarding point 8 in the background technology, a pivot structure is set between the telescopic rod and the main rod. Under normal conditions, the main rod can only rotate in the direction of pushing and feeding. Therefore, even if there is an undesirable return, such as the motor reversing, the non-rigid pivot structure will not push the terminal belt to move in the opposite direction, and the inclined surface and rounded corner of the adapter block will not damage the material.

[0034] Note: The above designs are not in any particular order, and each one makes the present invention different from the prior art and a significant advancement. Attached Figure Description
