This type of structure includes a pressing rod, a needle foot at the lower end of the pressing rod, and a spring sleeved outside the needle foot. At present, the three are assembled by manual work, which is time-consuming and laborious, and it is difficult to reduce labor costs. At the same time, the tip of the needle foot is also easy to injure the worker during assembly, so a device suitable for jump needle of compass pen is needed. SUMMARY

[0003] Based on the above problems, the present application aims to provide a compass pen jump needle machine which can quickly install the needle foot and spring of the compass pen.

[0004] In view of the above problems, the following technical scheme is provided: a compass pen jump needle machine, comprising a rack, the rack is provided with an intermittent rotating work station turntable, the outer edge of the work station turntable is provided with a plurality of pen jump grooves which are uniformly distributed along the circumferential direction thereof; the rack is further provided with a pen jump feeding station, a needle foot feeding station, a spring feeding station and a discharging station which are sequentially arranged along the rotating direction of the work station turntable and correspond to the pen jump grooves; the pen jump feeding station is provided with a feeding channel, the end of the feeding channel is connected with the pen jump groove of the station to send the pen jump into the pen jump groove; the needle foot feeding station comprises a lifting seat driven to lift by a lifting device, the lifting seat is provided with a needle head connected with a needle feeding channel, the lifting seat is further provided with a needle feeding slider, the needle feeding slider is provided with a lifting cylinder located below the needle head for receiving the falling needle foot, the lifting seat is further provided with a swing lever hinged to the lifting seat or the needle feeding slider, one end of the swing lever is located below the lifting cylinder, and the other end of the swing lever is matched with a stop block on the rack; after the lifting cylinder receives the needle foot, the lifting cylinder is pushed away from below the needle head and reaches below the pen jump, and then the lifting device drives the lifting seat to rise to make one end of the swing lever abut against the stop block and the other end of the swing lever to push the needle foot into the lower end of the pen jump; the spring feeding station comprises an installation plate which is lifted in linkage with the lifting device, the installation plate is provided with a spring channel for conveying the spring, and the installation plate is further provided with a spring feeding slider, the spring feeding slider is provided with a spring containing hole, and the spring containing hole driven by the spring feeding slider slides between below the spring channel and below the pen jump.

[0005] In the above structure, the pen jump is fed into the pen jump slot of the station turntable via the feeding channel of the pen jump feeding station. Then, the station turntable is driven to rotate by a cam divider or a servo / stepper motor, causing the pen jump to reach the needle feeding station. After receiving the needle that has fallen from the needle outlet, the lifting cylinder of the needle feeding station pushes the lifting cylinder from below the needle outlet to below the pen jump. Then, the lifting device drives the lifting seat to rise, bringing the lifting cylinder closer to below the pen jump. At the same time, as the swing arm rises with the lifting seat, one end abuts against the stop block, causing the other end to rise and push the lifting cylinder, so that the lifting cylinder... The needle feed slider rises to push the needle into the needle insertion cylinder at the bottom of the pen jump; then the station turntable drives the pen jump to the spring feeding station, where the spring falling from the spring channel enters the spring receiving hole of the spring feed slider. The spring feed slider then drives the spring in the spring receiving hole to the bottom of the pen jump. At this time, the lifting device drives the mounting plate to rise, so that the spring is sleeved outside the needle insertion cylinder to realize the installation of the spring; then the station turntable drives the pen jump to the discharge station to discharge the material. Since the lifting device simultaneously drives the needle feeding station and the spring feeding station during the lifting process, the pure mechanical linkage can ensure the reliability of the installation.

[0006] The present invention is further configured such that the pen feeding station also includes a pen feeding vibratory plate connected to the feeding channel; the needle feeding station also includes a needle feeding vibratory plate connected to the needle feeding channel; and the spring feeding station also includes a spring vibratory plate connected to the spring channel.

[0007] In the above structure, the pen jump vibratory feeder is used to arrange the pen jumps into the feeding channel; the needle foot vibratory feeder is used to arrange the needle feet into the needle feeding channel; and the spring vibratory feeder is used to arrange the springs into the spring channel.

[0008] The present invention is further configured such that the needle feeding slider is driven by a needle feeding cylinder.

[0009] In the above structure, when the needle feeding cylinder is pushed, its impact vibration can assist the needle in the needle feeding channel to fall down, thereby improving the reliability of needle feeding.

[0010] The present invention is further configured such that the spring-feeding slider is pushed by a spring-feeding cylinder.

[0011] In the above structure, when the spring-feeding cylinder is pushed, its impact vibration can assist the spring in the spring channel to fall, thereby improving the reliability of spring feeding.

[0012] The present invention is further configured such that a first abutment block is provided above the pen skip groove corresponding to the needle feeding station.

[0013] In the above structure, the first stop block prevents the pen jumper from being pushed up by the pin when the pin is attached to the pen jumper.

[0014] The invention is further configured such that a second abutment is provided above the pen skip groove corresponding to the spring feeding station.

[0015] In the above structure, the second stop block prevents the pen jump from being pushed up by the spring when the spring is mounted on the pen jump.

[0016] The present invention is further configured such that an auxiliary pressure plate is provided on the station turntable in the direction of the needle feeding station toward the spring feeding station, which is arranged along the path of the pen jump groove. The auxiliary pressure plate is provided with a guide bevel on the side near the needle feeding station for assisting in pressing down the top pressing cap of the pen jump.

[0017] In the above structure, the auxiliary pressure plate is used to assist in pressing down the pen cap of the pen jump, and the guide slant can guide the pen jump to press down.

[0018] The present invention is further configured such that the discharge station includes a stripping block located below the station turntable, the stripping block gradually tilting outward from the station turntable in the rotation direction of the station turntable; and a discharge port is provided below the stripping block.

[0019] In the above structure, when the station turntable rotates, the stripping block abuts against the lower end of the pen jump, pushing the pen jump out of the pen jump slot and causing it to fall into the discharge port.

[0020] The beneficial effects of this invention are as follows: The pen jump is fed into the pen jump slot of the station turntable via the feeding channel of the pen jump feeding station. Then, the station turntable is driven to rotate by a cam divider or a servo / stepper motor, causing the pen jump to reach the needle feeding station. After receiving the needle that has fallen from the needle outlet, the lifting cylinder of the needle feeding station pushes the lifting cylinder from below the needle outlet to below the pen jump. Then, the lifting device drives the lifting seat to rise, bringing the lifting cylinder closer to below the pen jump. At the same time, as the swing arm rises with the lifting seat, one end abuts against the stop block, causing the other end to rise and push the lifting cylinder, thus raising the pen jump. The lowering cylinder rises relative to the needle feeding slider, pushing the needle into the needle insertion cylinder at the lower end of the pen jump. Then, the station turntable drives the pen jump to the spring feeding station. The spring falling from the spring channel enters the spring receiving hole of the spring feeding slider. Then, the spring feeding slider drives the spring in the spring receiving hole to the bottom of the pen jump. At this time, the lifting device drives the mounting plate to rise, so that the spring is sleeved outside the needle insertion cylinder to realize the installation of the spring. Then, the station turntable drives the pen jump to the discharge station to discharge the material. Since the lifting device simultaneously drives the needle feeding station and the spring feeding station during the lifting process, the pure mechanical linkage can ensure the reliability of the installation.
