In some examples, after the terminal feeding device 100 cuts the terminal 2 on the terminal strip 23, the terminal conveying device 200 is taken away and conveyed to the crimping position 300 at the crimping station. The first knife rest 1023 on the terminal supply device 100 can clamp the terminal 2 and move to the initial position of the clamping jaw 201 under the driving of the linear sliding table transfer assembly, so that the clamping jaw 201 can take the terminal 2 away from the first knife rest 1023. Thereby improving the carrying efficiency of the terminal 2.

In some examples, the crimping device 300 of the present invention is described in conjunction with fig. 9 and 10. The crimping apparatus 300 includes a plurality of pairs of crimping dies 301 and a terminal machine 302.

Each crimping die 301 includes a first die support 3011, a first die body 3012, a first stopper 3013, a second die support 3014, a second die body 3015, and a second stopper 3016; the first die body 3012 is located on the base portion side of the terminal at the time of crimping, and the first die body 3012 is slidably inserted on the first die holder 3012; the first stopper 3013 is rotatably provided on the first mold support 3011 between a first limit position and a first avoidance position; when the first limiting piece 3013 is located at a first limiting position, the first limiting piece 3013 limits the first die body 3012 to slide, and when the first limiting piece 3013 is located at a first avoiding position, the first limiting piece 3013 removes the limitation on the first die body 3012; the second die support 3014 is arranged above the first die support 3011 in a liftable manner; the second die body 3015 is located on the vertical direction side of the terminal at the time of crimping, and the second die body 3015 is slidably engaged with the second die holder 3014; the second stopper 3015 is rotatably provided on the second die support 3014 between a second limit position and a second avoidance position; when the second stopper 3016 is located at the second stopper position, the second stopper 3016 restricts the second mold body 3015 from sliding, and when the second stopper 3016 is located at the second escape position, the second stopper 3016 releases the restriction on the second mold body 3015.

Therefore, the first die body 3012 is slidably inserted into the first die support 3011, the first stopper 3013 can limit the first die body 3012 to slide or release the limitation on the first die body 3012, the second die body 3015 can be slidably clamped on the second die support 3014, and the second stopper 3016 can limit the second die body 3015 to slide or release the limitation on the second die body 3015, so that when the first stopper 3013 and the second stopper 3016 are driven to rotate, the first die body 3012 and the second die body 3015 can be quickly replaced, the replacement efficiency of the crimping die is improved, and the quick replacement of crimping dies of different types is realized.

In some embodiments of the present invention, in conjunction with fig. 10, the first die support 3011 may have a substantially U-shaped mounting groove 30111, and the first die body 3012 is inserted into the mounting groove 30111 and slidable; in this manner, when the first mold body 3012 is mounted, the first mold body 3012 is pushed to the bottom from the entrance of the mounting groove 30111; when the first mold body 3012 is replaced, the first mold body 3012 is simply pulled out of the mounting groove 30111. In this example, the first stop 3013 can be a first swing plate, one end of which is hinged to the first die mount 3011 and the other end of which is a free end, and when the first swing plate rotates relative to the first die mount 3011, the free end of the first swing plate rotates from the first stop position to the first avoidance position or from the first avoidance position to the first stop position. Specifically, one end of the first swing plate is hinged to the first die mount 3011 via a first rotating shaft, and the other end is rotatable around the axis of the first rotating shaft by an external force. That is, when an external force is applied to the first swing plate, the free end of the first swing plate can be rotated from the first limit position to the first escape position or from the first escape position to the first limit position. It can be understood that when the free end rotates from the first avoiding position to the first limiting position, the plate body of the entire first swinging plate is located right in front of the sliding direction of the first die body 3012 to block the sliding of the first crimping die; when the free end rotates from the first limiting position to the first avoiding position, the plate body of the whole first swinging plate is staggered with the sliding direction of the first module 3012, so that the first module 3012 is not blocked. In this embodiment, when the free end of the first swinging plate rotates counterclockwise and the end of the free end extends out of the mounting slot 30111, the free end rotates from the first avoiding position to the first limiting position; when the free end of the first swinging plate rotates clockwise and the end part of the free end is positioned below the mounting groove 30111, the free end rotates from the first limit position to the first avoidance position.

Further, in order to ensure that the free end of the first swing plate is stably located at the first limit position, a damping fin is sleeved at a position where the first swing plate is hinged to the first die support 3011. The damper plate provides resistance to rotation of the first swing plate so that the first swing plate does not rotate when no external force acts.

In some embodiments, referring to fig. 10, the second die support 3014 may have hooks extending along the sliding direction of the second die body 3015, and the second die body 3015 may have a clipping platform on the side wall, so that the clipping platform clips the second die body 3015 on the hooks and can slide; thus, when the second die body 3015 is mounted, the clipping table is pushed in from one end of the clipping hook; when the second module 3015 is replaced, the second module 3015 is pulled out from the hook. In this example, the second stop 3016 can be a second swing plate having one end hinged to the second die mount 3014 and the other end being a free end, and the free end of the second swing plate rotates from the second stop position to the second retracted position or from the second retracted position to the second stop position when the second swing plate rotates relative to the second die mount 3014. Specifically, the second swing plate has one end hinged to the second die support 3014 via a second rotating shaft, and the other end rotatable around the axis of the second rotating shaft by an external force. That is, when an external force is applied to the second swing plate, the free end of the second swing plate can be rotated from the second limit position to the second escape position or from the second escape position to the second limit position. It can be understood that when the free end rotates from the second avoiding position to the second limiting position, the plate body of the entire second swing plate is located right in front of the sliding direction of the second die body 3015 to block the second crimping die from sliding; when the free end rotates from the second limiting position to the second avoiding position, the plate body of the whole second swinging plate is staggered with the sliding direction of the second module 3015, so as to release the blocking of the second module 3015. In this embodiment, when the free end of the second swing plate rotates clockwise and the end of the free end is located in the sliding direction of the second module body 3015, the free end rotates from the second escape position to the second limit position; when the free end of the second swing plate rotates counterclockwise and the end of the free end is offset from the sliding direction of the second die body 3015, the free end rotates from the second limit position to the second avoidance position.

Further, in order to ensure that the free end of the second swing plate is stably located at the second limit position, a damping fin is sleeved at a position where the second swing plate is hinged to the second die support 3014. The damper provides resistance to rotation of the second swing plate so that the second swing plate does not rotate when no external force is applied.

In some examples, the first die body 3012 includes a base plate and an anvil and a second seat disposed on the base plate, wherein the second seat is resiliently coupled to the base plate. The second mold body may be a crimper. A second cutter may be mounted on second die support 3014 and cooperate with the second blade seat to cut terminal waste from the terminals. Further, the second tool apron is elastically connected with the bottom plate through a spring. That is, when the second mold body 3015 is pressed down, the second tool seat will cooperate with the second cutter to cut the terminal waste from the terminal under the support of the spring.

With reference to fig. 9, the crimping die 301 further includes a crimping frame 3017, the crimping frame 3017 has a first bracket and a second bracket, the first bracket and the second bracket are parallel to each other and are disposed below the second bracket, the first die support 3011 is mounted on the first bracket, and the second die support 3014 is mounted on the second bracket. Wherein, the second die support 3014 is arranged on the second bracket in a lifting way. Specifically, the second die mount 3014 may be slidably mounted on the second bracket in the vertical direction, and the second die mount 3014 may be connected by a ram on the terminal machine 302, so that the second die mount 3014 may be pressed down to perform the crimping action.

In some examples, a plurality of first mold supports 3011 are horizontally arranged in parallel on the first support, a first mold body 3012 is installed on each first mold support 3011, a plurality of second mold supports 3014 are horizontally arranged in parallel on the second support, a second mold body 3015 is installed on each second mold support 3014, and the plurality of first mold bodies 3012 and the plurality of second mold bodies 3015 correspond to each other one by one to define a plurality of crimping portions together. That is, a plurality of pairs of crimping dies 301 are arranged on the crimping frame 3017, so that the plurality of pairs of crimping dies 301 can correspond to a plurality of types of terminals and electric wire designs; and the terminal machine 302 can be provided with a sliding plate 3021, so that each pair of crimping dies 301 can slide onto the pressing head to complete the crimping action under the action of the pressing head and the driving motor.

Note that the first support and the first die support 3011 are integrally formed, and a plurality of first die supports 3011 can be formed by providing a plurality of U-shaped mounting grooves 30111 on the first support. Of course, a plurality of first die supports 3011 may be assembled to the first support.

Further, the terminal machine 302 further includes: a base 3022 and a third driver 3023. A slide rail is arranged on the base 3022, the slide rail is arranged along the horizontal arrangement direction of the plurality of first die supports 3011, and the bottom surface of the crimping frame 3017 is connected with the slide rail in a sliding manner; the third driver 3023 drives the crimping frame 3017 to slide on the slide rails so that each crimping section can move. That is, the third driver 3023 can drive the entire crimp frame 3017 with the crimp dies 301 mounted thereon to slide on the base 3022; in this manner, when the crimping of the terminal and the electric wire of a different type are switched, the crimping frame 3017 is driven to move so that the second die holder 3014 corresponding to the type of the terminal is connected to the ram of the terminal machine 302, and of course, the first die holder 3011 corresponding to the second die holder 3014 also moves in synchronization. In this embodiment, the third driver 3023 may be a motor-driven screw structure.

In addition, the driving force of the terminal machine 302 for driving the crimping die 301 to complete the crimping action can be numerical control, and the numerical control can be adjusted according to the crimping height required by the terminals of different models; wherein, a pressure monitor is also arranged on the terminal machine 302 to match with the numerical control driving force to adjust the crimping height of the terminals of various types.
