Description

Technical Field

[0001] The utility model relates to the technical field of jewelry handicraft processing, and more specifically to an automatic discharging device for a jewelry injection molding machine. Background Art

[0002] In daily production, the temperature of the blank products demolded from the injection molding machines for jewelry and handicrafts is very high. Few manufacturers still manually remove the materials wearing anti-scalding gloves. Most manufacturers have purchased robots to replace them, which is not only efficient, but also improves production safety and reduces the incidence of injuries.

[0003] However, in actual production, the manufacturer found that the customized robot and the original injection molding machine control system in the factory were independent, and there would be a coordination problem here. The time for the robot to reach in and out of the injection molding machine box to pick up materials must match the time of opening and closing the injection molding machine box door. When the robot was first installed in the factory, the robot manufacturer would help debug the robot program to achieve matching time. However, during later use, such as power outages in the workshop, maintenance of the injection molding machine, etc., the robot needs to be re-debugged to match the time, which is more troublesome. The robot manufacturer's visit not only incurs expenses, but also may not be timely, which will affect the production progress, so the jewelry manufacturers are also complaining. Utility Model Content

[0004] The purpose of the utility model is to overcome the above defects of the prior art and provide an automatic discharging device for a jewelry injection molding machine. The box door of the injection molding machine is removed and replaced by a box door configured on a mechanical mobile phone frame. The baffle is the box door. In this way, the baffle and the manipulator can consistently self-adapt to the coordination time in the same control program, which saves the troubles of jewelry manufacturers. In any case of power outage in the workshop, maintenance of the injection molding machine, etc., the production progress will not be affected.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical scheme: an automatic discharging device of a jewelry injection molding machine, comprising a pair of first frames and second frames distributed vertically but independently of each other, a rodless cylinder arranged along its length direction is provided on the first frame, a slide is provided on the piston of the rodless cylinder, a rotating cylinder with horizontal rotational movement is provided on the slide, an arm extending horizontally outward is provided on the rotating cylinder, a finger cylinder is provided on the free end of the arm, and a conveyor belt arranged along its length direction is provided on the second frame, characterized in that a first gantry is provided on one end of the first frame, a pair of sliding sleeves arranged side by side are provided on the first gantry, a sliding rod is provided in each of the two sliding sleeves, and a shaft sleeve is provided on each of the two free ends of each sliding rod, and the four shaft sleeves are mounted on a baffle in a matrix manner, a lifting cylinder is provided between the two sliding sleeves on the first gantry, a fisheye joint bearing is provided on the free end of the cylinder shaft of the lifting cylinder, and the fisheye joint bearing is mounted on the baffle.

[0006] The utility model removes the box door of the injection molding machine and configures the box door on the mechanical mobile frame instead. The baffle is the box door. In this way, the baffle and the manipulator can always self-adapt to the time in the same control program, which saves the troubles of the jewelry manufacturers. The production progress will not be affected by any power outage in the workshop, maintenance of the injection molding machine, etc.

[0007] The first frame and the second frame exist independently. The first frame can flexibly adjust its position to allow the baffle to align with the removed injection molding machine box door, so that the baffle fits the box door without any difference. At the same time, the second frame can flexibly adjust its coordination position with the first frame and the robot of the next program, killing two birds with one stone.

[0008] Preferably, a vertical expansion area of ​​the baffle is larger than a vertical expansion area of ​​the first gantry.

[0009] The baffle can be enlarged as soon as possible to cover the robot arm, thereby sealing the window of the injection molding machine and replacing the injection molding machine cabinet door.

[0010] Preferably, a second gantry is provided in the middle of the second frame, and at least one cooling fan is provided on the second gantry.

[0011] The temperature of the blank products demoulded by the injection molding machine for jewelry and handicrafts is very high. When they are transported on the conveyor belt, there is no other interference, so they can be equipped with a cooling fan for cooling.

[0012] Preferably, there are three cooling fans, one of which is arranged in the middle of the second gantry, and the other two are symmetrically distributed on both sides of the second gantry.

[0013] One cooling fan blows in the direction of the conveyor belt feeding, one cooling fan blows on the way, and one cooling fan blows in the direction of the conveyor belt passing the material. The material is cooled by blowing at three angles.

[0014] Preferably, a pair of face-to-face parallel push cylinders are provided at the end of the second frame away from the first frame, and a push plate is respectively provided on the free end of the cylinder shaft of the two parallel push cylinders. The two push plates face each other to perform a clutch movement of approaching and separating.

[0015] The jewelry and handicraft blanks are transported by the conveyor belt and bumpy on the way, and their positions on the conveyor belt will change to some extent. When they are transported to the end of the second rack, the robot of the next program will grab them. If the positions are not at the same point, it will be difficult for the robot to grab them. Therefore, a pair of push plates are arranged at the end of the second rack to push the jewelry and handicraft blanks to the center of the conveyor belt from both sides. In this way, the position is fixed each time, and it is convenient for the robot to grab them, thereby improving work efficiency.

[0016] Beneficial effect: The utility model removes the box door of the injection molding machine and configures the box door on the robot frame instead, so that the box door and the robot can consistently self-adapt to the coordination time in the same control program.
