[0039] Please refer to Figures 1 to 4 The utility model provides a kind of classification of injection molding piece discharging device, including manipulator 1, support frame 2, first discharge pipe 3, second discharge pipe 4, first material box 5 and second material box 6.

[0040] Among them, the support frame 2 is used to install first discharge pipe 3 and second discharge pipe 4. The first discharge pipe 3 and second discharge pipe 4 are mirror image, and the first discharge pipe 3 and second discharge pipe 4 form inverted V shape together. The manipulator 1 is used to move injection molding piece (for example, helmet plug buckle) out of injection molding machine, and make injection molding piece be respectively put into first discharge pipe 3 and second discharge pipe 4, and the first material box 5 is located below first discharge pipe 3, and the second material box 6 is located below second discharge pipe 4, so that the first material box 5 and the second material box 6 can receive injection molding piece discharged by two different discharge pipes respectively.

[0041] It can be seen that by installing first discharge pipe 3 and second discharge pipe 4 on support frame 2, different shapes of plastic parts can be conveyed in different discharge pipes, so as to fall into different material boxes, realizing the classification of a plurality of shapes of plastic parts, without manual classification of plastic parts in the same material box, so as to reduce labor cost.

[0042] In addition, by making first discharge pipe 3 and second discharge pipe 4 form inverted V shape together, the discharge point of manipulator 1 can be located at the same position, so as to ensure that manipulator 1 can put two shapes of plastic parts at a time.

[0043] As Figures 1 to 3 Indicated, in a preferred embodiment of the present application, the manipulator 1 includes driving assembly 11, turnover cylinder 12 and material taking plate 13.

[0044] The tilting cylinder 12 is mounted on the drive assembly 11, which drives the tilting cylinder 12 to move in the X-axis, Y-axis and Z-axis directions. The material taking plate 13 is connected to the power output end of the tilting cylinder 12. When the tilting cylinder 12 is working, the material taking plate 13 can swing between the vertical plane and the horizontal plane, so that the material taking plate 13 can take out the plastic part in the injection molding machine (at this time, the material taking plate 13 is perpendicular to the horizontal plane). When the drive assembly 11 drives the tilting cylinder 12 to move to the upper end of the two feed tubes, the material taking plate 13 can put the material down (at this time, the material taking plate 13 is parallel to the horizontal plane).

[0045] To ensure that the material picker plate 13 can remove the injection molded part from the injection mold, a material picker rod 14 is provided on the side of the material picker plate 13 away from the flipping cylinder 12. The material picker rod 14 can extend into the plastic part (such as a buckle), and when the material picker rod 14 moves upward, it can support the plastic part, thereby enabling the transfer of the plastic part.

[0046] In addition, two sets of picking rods 14 are arranged side by side, each set of picking rods 14 is used to transfer plastic parts of the same shape. When the drive assembly 11 drives the tilting cylinder 12 and the picking plate 13 to move above the two feeding tubes, and the picking plate 13 is tilted to be parallel to the horizontal plane, the two sets of picking rods 14 are exactly above the inlet of the two feeding tubes, thereby enabling the robot arm 1 to feed two different shapes of plastic parts into the two feeding tubes at the same time.

[0047] It is understandable that the activities of the robotic arm 1 can be realized through programming, and of course, the use of sensors can also be used to make the picking plate 13 move automatically and accurately to the picking and unloading positions of the plastic parts.

[0048] like Figure 1 As shown, in a preferred embodiment of the present invention, both the first discharge pipe 3 and the second discharge pipe 4 include a guide section 301 and a feed section 302; the guide section 301 is inclined downward so that the plastic parts falling into the pipe can fall into the central area of ​​the material box, avoiding the accumulation of plastic parts on one side of the material box and affecting the collection of plastic parts.

[0049] The feeding section 302 is located at the upper end of the guiding section 301 and is connected to the guiding section 301; the two feeding sections 302 are arranged side by side, thereby ensuring that when the picking plate 13 is flipped to be parallel to the horizontal plane, the two sets of picking rods 14 are exactly above the feeding ports of the two feeding pipes.

[0050] like Figure 1 As shown, in a preferred embodiment of the present invention, the drive assembly 11 includes a frame 111, a Y-axis drive mechanism 113, an X-axis drive mechanism 112, a Z-axis drive mechanism 114, a movable seat 115, a limit switch 116, and a controller.

[0051] The controller controls the operation of the X-axis driving mechanism 112, the Y-axis driving mechanism 113 and the Z-axis driving mechanism 114. The X-axis driving mechanism 112, the Y-axis driving mechanism 113 and the Z-axis driving mechanism 114 are all prior art, and the operation principle is consistent with the existing ball screw 721 linear module.

[0052] The Y-axis driving mechanism 113 is arranged on the rack 111, the X-axis driving mechanism 112 is arranged on the output end of the Y-axis driving mechanism 113, the Z-axis driving mechanism 114 is arranged on the output end of the X-axis driving mechanism 112, and the movable seat 115 is connected with the output end of the Z-axis driving mechanism 114, and the movable seat 115 is connected with the turnover cylinder 12 through the movable frame arranged downwardly. Therefore, through the cooperation of the Y-axis driving mechanism 113, the X-axis driving mechanism 112 and the Z-axis driving mechanism 114, the turnover cylinder 12 provided with the material taking plate 13 can be moved in the X, Y and Z directions, so that the mechanical arm 1 can normally discharge materials.

[0053] The travel switch 116 is arranged on the lower side of the Z-axis driving mechanism 114, and the travel switch 116 is used for detecting the movable seat 115, so as to control the lowest position of the downward movement of the movable seat 115, thereby avoiding that the dropping position of the plastic part is too high, and the situation that the plastic part is broken due to collision when falling into the material box can be improved. The controller is electrically connected with the travel switch 116. When the travel switch 116 detects the movable seat 115, the controller can control the Z-axis driving mechanism 114 and the turnover cylinder 12 based on the detection signal of the travel switch 116, so that the movable seat 115 can stop moving downwardly, and the turnover cylinder 12 can also turn over the material taking plate 13, so that the plastic part can fall into the discharge pipe.

[0054] As shown in Figure 1 and Figure 4 In a preferred embodiment of the utility model, the support frame 2 includes a support column 201 and a cross beam 202 horizontally arranged on the upper end of the support column 201. The support column 201 can be moved, and when injection molding production is not needed, the support frame 2 can be moved to the edge of the production site. The first discharge pipe 3 and the second discharge pipe 4 can be detachably arranged on the end of the cross beam 202, and the discharge pipe does not need to be installed by welding, thereby reducing the installation difficulty of the discharge pipe.

[0055] In order to realize detachable installation of the first downcomer pipe 3 and the second downcomer pipe 4, the support frame 2 further comprises an L-shaped connecting piece 203; one side of the L-shaped connecting piece 203 is detachably connected (for example by screwing) on the first downcomer pipe 3 and the second downcomer pipe 4, and the other side of the L-shaped connecting piece 203 is detachably connected on the cross beam 202, so that through one connecting piece, simultaneous installation of two downcomer pipes can be realized.

[0056] The above merely describes the preferred embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields, or the like made by using the content of the present application specification and drawings under the inventive concept of the present application are included in the patent protection scope of the present application.
