Description

TECHNICAL FIELD

[0002] Insert injection molding is a process in which an insert is fixed in a proper position in an injection mold in advance, then plastic is injected for molding, and the insert is tightly embedded in the plastic after the mold is opened to obtain a product. When insert injection molding products are molded, the simplest operation method is to place the insert in the corresponding position of the injection molding mold by a mechanical hand device.

[0003] The structure of the insert is shown in Figure 15 The insert includes a plate body and extension plates extending away from the plate body from both sides of one end of the plate body, the extension plates and the plate body integrally form a T shape, and a rectangular mounting hole is formed in the plate body. When the insert is loaded into the injection mold, the two inserts need to be placed in the manner shown in Figure 15 Then the mechanical hand takes them and then sends them into the injection molding mold. However, the current operation method of placing the insert by the mechanical hand device still needs manual placement of the insert on the mechanical hand gripping position to ensure the position accuracy of the mechanical hand device in gripping the insert. Thus, the mechanical hand device needs to wait for manual placement of the insert on the mechanical hand gripping position every time the insert is transferred, which is low in automation and needs manual cooperation. If the insert is not placed by the manual cooperation, the entire injection molding process will be stopped, which will reduce the efficiency of the injection molding machine. In addition, how to take and place the insert by the mechanical hand is also a problem to be solved.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] Embodiment 1: A full-automatic insert feeding machine, like Figure 1 and Figure 2 , comprising transmission tracks 1, a mechanical hand, a distribution part, and a feeding mechanism for feeding inserts 2 (not shown in the figure) one by one to the transmission tracks 1, the distribution part moves a single insert 2 at the outlet of the transmission track 1 to a grabbing position for the mechanical hand to grab, and the side of the distribution part abuts against the outlet position of the transmission track 1; the number of the transmission tracks 1 is set to be multiple and horizontally distributed in parallel, preferably two transmission tracks 1, the feeding mechanism comprises a vibrating disc 11 for feeding inserts 2 one by one to each transmission track 1, each transmission track 1 is horizontally distributed, and the bottom of the transmission track 1 is provided with a straight vibrator 13.

[0023] The distribution of the inserts 2 in the two transmission tracks 1 is that one insert 2 is next to another insert 2, and the side of one of the adjacent two inserts 2 with the extension plate 22 is in abutment with the other, the side of the insert 2 with the extension plate 22 on one of the transmission tracks 1 is close to the side of the insert 2 with the extension plate 22 on the other transmission track 1 (as shown inFigure 11 The robot arm is provided with an end effector, and the dispensing part moves the insert 2 to the grabbing position, and then the end effector sucks the insert 2 from the dispensing part; the end effector is matched with an ejector, and when the end effector releases the suction force of the insert, the ejector ejects the insert 2 from the end effector, so that the insert 2 enters the injection mold.

[0024] The end effector is provided with a fixed plate 14 arranged on the robot arm, and the fixed plate 14 is connected with a grabbing plate 142 through two opposite vertical plates 141.

[0025] The end effector includes a fixed plate 14 arranged on the robot arm, and the fixed plate 14 is connected with a grabbing plate 142 through two opposite vertical plates 141. Figure 2 The grabbing plate 142 is provided with two suction blocks 143 matched with the shapes of the two inserts 2 output by the two transmission tracks 1. Figure 4 The suction blocks 143 are provided with corresponding holes 144 corresponding to the mounting holes 23 on the inserts 2, and the sizes of the corresponding holes 144 are greater than the sizes of the mounting holes 23. Figure 6 The suction blocks 143 are provided with suction pipes 145 on both sides of the corresponding holes 144, and the ends of the suction pipes 145 away from the suction blocks 143 are connected with a vacuum pump (not shown in the figure). Figure 8 The vacuum pump makes the suction pipes 145 generate suction force on the inserts 2, and the ejector is arranged on the fixed plate 14 and ejects the inserts 2 from the suction blocks 143 through the corresponding holes 144. The design aims to suck the inserts 2 on the grabbing position to the suction blocks 143 through the two suction pipes 145 when the inserts 2 are taken, then the robot arm moves the inserts 2 into the injection molding machine, and the suction blocks 143 place the inserts 2 into the injection mold, then the suction pipes stop suction, and the ejector ejects the inserts 2 into the injection mold through the corresponding holes 144, thereby completing the work of embedding the inserts 2 into the injection mold.

[0026] The injection mold is provided with a hole for placing the inserts 2, which is an existing structure, so the robot arm only needs to move the inserts 2 to the injection mold and opposite to the hole for placing the inserts 2, then insert a part of the suction blocks 143 with the inserts 2 into the hole for placing the inserts 2 in the injection mold, and then the ejector ejects the inserts 2 into the corresponding position of the injection mold.

[0027] The end effector includes a fixed plate 14 arranged on the robot arm, and the fixed plate 14 is connected with a grabbing plate 142 through two opposite vertical plates 141. Figure 6 The grabbing plate 142 is provided with two suction blocks 143 matched with the shapes of the two inserts 2 output by the two transmission tracks 1. Figure 7The ejector includes a moving plate 146 arranged on the side of the grabbing plate 142 away from the suction block 143. The grabbing plate 142 is provided with a plurality of guide rods 147 penetrating the moving plate 146. The moving plate 146 is provided with an electric cylinder 148 on the side away from the grabbing plate 142. The piston rod of the electric cylinder 148 extends vertically downward and is fixed to the plate surface of the grabbing plate 142 penetrating the moving plate 146. The corresponding hole 144 on the suction block 143 penetrates the upper end surface of the grabbing plate 142. The moving plate 146 is provided with a top rod 149 moving in the corresponding hole 144. The end of the top rod 149 moving out of the corresponding hole 144 is provided with a pointed end 1491. On the one hand, the pointed end 1491 of the top rod 149 is arranged to enter the mounting hole 23 of the insert 2. On the other hand, the pointed end 1491 is arranged to abut against the hole wall of the mounting hole 23 after entering the mounting hole 23, thereby pushing the insert 2. At this time, the rod diameter of the top rod 149 is greater than the hole diameter of the mounting hole 23.

[0028] As Figure 2 and Figure 4 and Figure 6 Two vibrating plates 11 are used to feed the inserts 2 into two parallel transmission tracks 1 one by one, so that the inserts 2 are closely arranged in the transmission tracks 1. At this time, the straight vibrator 13 moves the inserts 2 on the transmission tracks 1 away from the vibrating plates 11, thereby moving out of the outlets of the transmission tracks 1. The distributor moves the single insert 2, so that the inserts 2 on each transmission track 1 are moved to the grabbing position of the robot one by one. Then, the robot moves the grabbing plate 142 to the grabbing position, so that the two suction blocks 143 are opposite to and contact the two inserts 2. Then, the air suction pipe 145 starts to suck air, thereby sucking the inserts 2 to the suction blocks 143. Finally, the robot moves the inserts 2 to the injection mold of the injection molding machine. Then, the suction of the inserts 2 is released, so that the ejector pushes the inserts 2 into the injection mold. The above process realizes the automatic placement of the two inserts 2 into the grabbing position of the robot, so as to facilitate the automatic grabbing of the robot. After grabbing, the inserts are pushed into the injection mold, thereby improving the automation degree of the insert 2 feeding, reducing the labor, facilitating the whole injection molding process, and improving the efficiency of the injection molding machine.

[0044] As shown in Figures 9-14 , the working principle of the distributing member: First step: two vibration plates 11 respectively deliver inserts 2 into two transmission tracks 1 one by one until the first insert 2 enters the straight track 16 at the outlet of the transmission track 1, at this time each roller 1671 rolls on the upper end surface of the first insert 2, when one end of the first insert 2 passes through the aperture of the through hole 1663 and is detected by the position sensor two 1667, at this time the position sensor two controls the electric cylinder three 1633 to push the long strip plate 165 upward, so that the rectangular block 1662 moves upward until the roller two 1668 on the positioning rod 1665 abuts against the lower end surface of the first insert 2, and the positioning rod 1665 moves into the sliding groove 1664 by a part, compressing the compression spring 1666 to have elastic restoring force, and the elastic restoring force does not limit the first insert 2 to continue to slide into the straight track 16; when the first insert 2 does not pass through the through hole 1663, the positioning rod 1665 and the rectangular block 1662 are located in the through hole 1663, and the compression spring 1666 is in a natural state; Second step: as the first insert 2 continues to enter the straight track 16, the mounting hole 23 on the first insert 2 moves to the opposite side of the positioning rod 1665, the positioning rod 1665 moves upward under the action of the restoring force of the compression spring 1666, and is automatically inserted into the mounting hole 23, realizing the positioning of the first insert 2; Third step: the electric cylinder two 164 drives the two straight tracks 16 to move, so that the straight tracks 16 are out of position with the transmission tracks 1, and the straight tracks 16 are located directly below the adjusting frame 171; Fourth step: the piston rod of the electric cylinder three 1633 extends upward and drives the long strip plate 165 to move upward, thereby supporting the lower end surface of the first insert 2 to move upward, at this time the positioning rod 1665 is in the mounting hole 23, as the rectangular block 1662 moves upward, the first insert 2 moves in the direction of the adjusting frame 171, if the first insert 2 can pass into the adjusting frame 171, it indicates that the direction of the first insert 2 is correct, if the direction of the first insert 2 is not correct, it will be clamped at the lower end surface of the adjusting frame 171 and press the pressure sensor, the pressure sensor senses the pressure and sends a signal to the controller, the controller first controls the electric cylinder three 1633 to drive the long strip plate 165 to move downward by a distance, and then controls the motor 166 to rotate by 180°, at this time the direction of the first insert 2 is turned correctly, the electric cylinder three 1633 drives the long strip plate 165 to move upward again, so that the first insert 2 passes into the adjusting frame 171 until the upper end surface of the first insert 2 moves to the upper end surface of the adjusting frame 171, at this time it is the grabbing position of the mechanical hand.

[0045] The above steps can be repeated to realize the continuous feeding of the inserts 2; When the upper end surface of the first insert 2 moves to the upper end surface of the adjusting frame 171, a position sensor three can be arranged on the inner wall of the adjusting frame 171, and then the mechanical arm is moved into the cabinet 15 to be grabbed, or other sensors can be arranged to control the mechanical arm, which is not limited herein.
