Description

Technical Field

[0001] The present invention relates to the field of wire harness or cable processing, and in particular to a terminal crimping system. Background Art

[0002] Wire harnesses, cables, and wires are commonly used components in the existing technology. During their widespread use, there is a need to dock or connect with other equipment. The connection needs to be achieved through terminals, so the wire harnesses need to be processed. The processing process includes winding, feeding, straightening, cutting, stripping, crimping, terminal delivery and other processes.

[0003] In actual engineering practice, the following problems exist:

[0004] 1. In existing wire harness processing, not only the wires but also the terminals need to be fed before the wire harness and the terminals can be docked, and crimped after docking. The terminal conveying process requires a drive structure to drive the terminal feed. Multiple terminals are fed in a strip, and then cut and crimped one by one. However, common belt conveyors often use active and driven rollers to achieve conveyor belt transportation. During the terminal strip conveying process, it needs to be cut continuously, which makes it impossible to convey it using conventional belt conveying methods.

[0005] Second, there are also methods other than roller conveying in the prior art to drive conveying and feeding, but the driving source of such feeding is generally hydraulic or pneumatic. However, the accuracy of hydraulic or pneumatic feeding is difficult to control. Even if high-precision feeding can be achieved, it requires the use of multiple components such as sensors, controllers, and communicators, which is relatively costly.

[0006] 3. In the existing technology, the trajectory control problem is an important issue for cyclic feeding.

[0007] 4. The cyclic rotation structure of the prior art will have more trajectory interference during the rotation process.

[0008] 5. The cyclic rotation structure of the prior art does not have a good structure for controlling the trajectory change.

[0009] 6. The push-type feeding in the prior art is limited to pushing a single object. The terminal conveyor belt includes multiple terminals and is soft in nature, and cannot well push the entire soft belt to move.

[0010] 7. The putter of the prior art has poor quality and short service life.

[0011] 8. During the pushing process of the push rod in the prior art, there may be unexpected return, such as motor reverse rotation, which may cause unexpected movement or damage to the conveyor belt. Summary of the Invention

[0012] In order to overcome the above problems, the present invention proposes a solution to solve the above multiple problems at the same time.

[0013] The technical solution adopted by the present invention to solve its technical problems is: a terminal crimping system, including a conveying device, a crimping device, a transfer device, and a terminal strip, the crimping device including a main body, a connecting rod, a crimping cylinder, an actuator, a cutting block, and a base, the transfer device including a rotating part, a rotating rod, a slide rail, and a slider; the slider is provided with a driving wheel, a driven wheel, and a gripper, the gripper including a gripping part and a bending part; the main body is provided with a connecting rod, and the connecting rod is provided with a crimping cylinder, the actuator can move up and down in the crimping cylinder to crimp the terminal and the wire harness, the terminal strip includes a terminal and a connecting strip, a plurality of terminals are arranged on the connecting strip, and there are gaps between the terminals, the bottom end of the actuator is provided with a cutting block to cut the connecting strip, and the base receives the terminal and the wire harness to cooperate with the actuator for crimping;

[0014] The rotating member drives the rotating rod to rotate, and a slide rail is provided at the end of the rotating rod. The slider can slide on the slide rail. The rotation of the driving wheel drives the connected driven wheel to rotate. A gripper is connected to each of the axles of the driving wheel and the driven wheel. One end of the bent portion is connected to the axle and the other end is connected to the gripping portion. The gripping portion is used to grip the wiring harness.

[0015] The conveying device includes a motor, an output shaft, a cylinder body, 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 block, a second bracket, an arm, a connecting pipe, and a block rod; the connecting belt can move along the track, the output shaft of the motor extends upward, the cylinder body is vertically connected to the upper end of the output shaft, the telescopic rod can telescopically move in the cylinder body, a piston plate is provided at one end of the telescopic rod, a spring is provided between the piston plate and the inner wall of the cylinder, the main rod is pivotally connected to the bottom of the other end of the telescopic rod, and the cylinder is connected above, the push rod is provided below the main rod, the adapter block is provided below the push rod, and the adapter block includes an inclined surface;

[0016] The first and second brackets are respectively located on both sides of the terminal strip, the first bracket is provided with the stopper, and the stopper includes a curved surface; the upper end of the second bracket is provided with the arm rod, and the front end of the arm rod is provided with a connecting tube, the connecting tube is a square tube, the connecting tube does not include a lower wall, and an opening is provided on the side wall of the connecting tube, and the side edge of the opening is pivotally provided with the stopper, the stopper can be rotated toward the inside of the connecting tube and cannot be rotated outside the connecting tube; the connecting tube and the stopper are staggered up and down;

[0017] 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 the arc surface and is squeezed by the arc surface. When the telescopic rod moves to the end of the arc surface, the cylinder pushes the blocking rod away and enters the connecting tube. Then the motor rotates in the opposite direction, the cylinder moves in the connecting tube and 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 enters the next gap.

[0018] Preferably, a groove is provided on the arm at a position where the arm is connected to the connecting pipe.

[0019] Preferably, the groove is communicated with the connecting pipe.

[0020] Preferably, the cylinder can enter the groove to reserve space for returning the blocking rod.

[0021] Preferably, the adapter block includes a push surface.

[0022] Preferably, the pushing surface includes a flat surface and a curved surface.

[0023] Preferably, the diameter of the main rod is larger than the diameter of the push rod.

[0024] Preferably, the left end of the connecting pipe is open.

[0025] Preferably, the through hole is a square hole.

[0026] Preferably, the through hole and the opening are located on the same wall surface of the connecting pipe.

[0027] The beneficial effects of the present invention are:

[0028] 1. Regarding the first point raised in the background technology, the terminal conveyor belt is pushed by pushing and returning the push rod, which solves the problem of the belt conveyor being cut off.

[0029] 2. Regarding the second point raised in the background technology, the movement of the push rod is achieved by the motor, and the approach to or separation from the terminal strip is achieved by the telescopic rod. Therefore, a large number of sensors, controllers, and communicators can be replaced by only the motor.

[0030] 3. In response to the third point raised in the background technology, two rotating tracks are constructed. When pushing, the telescopic rod and the arc surface are coordinated to complete the position control of the push feed; when returning, the return track is used to make the push rod avoid the material and return, avoiding the collision between the push rod and the material to affect the position of the material or damage the material.

[0031] 4. Regarding the fourth point raised in the background technology, a cylindrical head is provided 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 up and down, and the positions of the cylinder and the telescopic rod are also different, thereby constructing two tracks that each realize their own functions.

[0032] 5. In response to the fifth point raised in the background technology, a one-way baffle is set at the intersection of the feed and return tracks. After the cylinder pushes the one-way baffle into the return track, it is blocked by the one-way baffle and cannot return. At the same time, a groove is set on the return arm to reserve more space so that the cylinder can be distanced from the baffle, so that the one-way baffle has enough space to return.

[0033] 6. In response to the sixth and seventh points raised in the background technology, a push rod is provided at the lower end of the main rod, and an adapter block is provided at the lower end of the push rod to adapt to the gap between the 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 pushing module, and the push rod and the adapter block below adapt to the size of the gap.

[0034] 7. In response to the eighth point raised in the background technology, a pivot structure is provided between the telescopic rod and the main rod. Under normal circumstances, the main rod can only rotate in the pushing and feeding direction. Therefore, even in the event of unexpected return, such as motor reversal, the non-rigid pivot structure will not push the terminal strip to move in the opposite direction, and the bevel and rounded corners of the adapter block will not damage the material.

[0035] Note: The above designs are not listed in any particular order, and each one makes the present invention distinctive and significantly advanced compared to the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
