Description

Technical Field

[0001] This application relates to the field of injection molded part processing technology, and in particular to an injection molded part sorting device. Background Technology

[0002] The production process of injection-molded toy parts involves injecting molten plastic raw material into a custom mold using an injection molding machine. After the raw material cools and solidifies, it forms a molded part, which includes the toy body and sprue. Sprue is waste material left in the raw material flow channel during the injection molding process. After the molded part is removed from the mold, it needs to undergo subsequent processes such as separating the product body and sprue before it can become a qualified toy component. Therefore, the molded part removal process is a key step connecting injection molding and subsequent processes, and it directly affects the smoothness of toy injection-molded part production.

[0003] In related technologies, after the injection mold is opened, the robotic arm drives the gripping component to move into the mold, and the molded part is taken out of the mold by the gripping component. Then the whole molded part is transferred to a designated area.

[0004] However, after the existing robotic arm picks up and transfers the molded parts as a whole, the operator needs to separate the product body from the sprue material one by one, which consumes extra time. Moreover, the manual separation speed is difficult to match the picking rhythm of the robotic arm and the production cycle of the injection molding machine, which can easily lead to the accumulation of molded parts in the temporary storage area, further slowing down the overall production process. Utility Model Content

[0005] To address the aforementioned problems, this application provides an injection molded part sorting device.

[0006] The injection molded part sorting device provided in this application adopts the following technical solution: A sorting device for injection molded parts includes a material picking mechanism and a support frame. The material picking mechanism includes a suction component and a clamping component. The clamping component is disposed in the middle of the support frame, and the suction component is disposed at the end of the support frame. The clamping component is used to clamp sprue material, and the suction component is used to clamp the product body. The support frame is slidably disposed.

[0007] By adopting the above technical solution, the clamping component holds the sprue material, the suction component suctions the corresponding product body, and the transfer is completed in conjunction with the sliding setting of the carrier frame. The clamping component and the suction component maintain an independent gripping state during the sliding transfer of the carrier frame. Not only can separation and transfer be achieved simultaneously, but the sprue material and the product body can also be transferred to the corresponding collection area according to the preset path to complete the classification and collection. Since the separation and classification actions are completed simultaneously with the transfer, the subsequent manual intervention is reduced. The operation speed can match the production cycle of the injection molding machine, effectively reducing the accumulation of molded parts in the temporary storage area due to the lag of manual separation and the confusion of classification. This reduces the occurrence of slowdown in the overall production process and ensures the continuity and efficiency of the production process.

[0008] Preferably, the suction assembly includes multiple suction cups and multiple first connecting tubes, the suction cups and the first connecting tubes are fixedly connected and communicate with each other, and the first connecting tubes are connected to an external air supply device.

[0009] By adopting the above technical solution, multiple suction cups form contact with the product body, and with the first connecting pipe of each suction cup connected to an external air supply device, the negative pressure suction of the suction cups can be adjusted to ensure that the product body is always stably adsorbed during the transfer process.

[0010] Preferably, it further includes a drive mechanism, the drive mechanism including a robotic arm, the support frame including a plurality of first support rods and a plurality of second support rods, the first support rods being connected to the robotic arm, the second support rods being fixed to the first support rods and perpendicular to each other, and the robotic arm being slidably disposed.

[0011] By adopting the above technical solution, the first and second support rods are fixed and perpendicular to each other, forming a stable three-dimensional support structure. This provides a stable installation benchmark for the clamping and suction components. The spacing between the clamping and suction components is rationally planned to ensure that the actions of the clamping component clamping the sprue and the suction component suctioning the product body do not interfere with each other. The robotic arm is fixedly connected to the first support rod. The robotic arm drives the first support rod to move, which in turn drives the support frame to move. When the robotic arm drives the support frame to slide and transfer, the clamping and suction components always maintain an independent gripping state, simultaneously completing the separation of the product body and the sprue. They are then transferred to the corresponding collection areas according to a preset path for classification and collection. The separation and classification actions are completed simultaneously with the transfer, reducing subsequent manual intervention. The operating speed can match the production cycle of the injection molding machine, ensuring the continuity and efficiency of the production process.

[0012] Preferably, a connecting component is provided between the second support rod and the suction cup, and the suction cup is fixed to the second support rod through the connecting component.

[0013] By adopting the above technical solution, the suction cup and the second support rod are fixed together by a connecting component. The connecting component realizes the positioning and installation of the suction cup on the second support rod, ensuring that the spacing between each suction cup is accurately matched with the gripping point of the product body. At the same time, it reduces the loosening and falling off of the suction cup due to changes in negative pressure suction or the sliding vibration of the robotic arm during the transfer process, ensuring that the product body is always stably adsorbed.

[0014] Preferably, the connecting component is slidably disposed on the second bearing rod.

[0015] By adopting the above technical solution, the connecting component is slidably set on the second support rod, so that the suction cup does not need to slide along the second support rod to adjust its position, and can adapt to the gripping point requirements of products of different sizes and shapes.

[0016] Preferably, the clamping assembly includes a gripper cylinder, which is disposed between the suction assemblies.

[0017] By adopting the above technical solution, the clamping component uses a gripper cylinder. The gripper cylinder has a stable and controllable clamping force, which reduces the slippage or deformation of the sprue material during the transfer process. The gripper cylinder is slidably set on the second bearing rod, which can form a coordinated adjustment with the sliding connection component of the suction component. According to the relative position of the sprue material and the product body in different product molding parts, the position of the gripper cylinder and the suction cup are adjusted synchronously.

[0018] Preferably, the clamping assembly further includes a second connecting pipe, which is fixedly connected to and communicates with the gripper cylinder, and the second connecting pipe is externally connected to an air supply device.

[0019] By adopting the above technical solution, the fixed connection and communication between the second connecting pipe and the gripper cylinder allows the air source of the air supply equipment to be transmitted to the inside of the gripper cylinder. This enables the gripper cylinder to output a suitable clamping force by adjusting the air source pressure according to the material, thickness, and size of the sprue material, thereby reducing the slippage of the sprue material during the transfer process due to insufficient clamping force.

[0020] Preferably, the drive mechanism further includes a drive component that drives the robotic arm to slide.

[0021] By adopting the above technical solution, the drive component can control the sliding trajectory, speed, and stopping position of the robotic arm. This allows the gripper cylinder to accurately align with the sprue grabbing point and the suction component to precisely adhere to the product's adsorption surface. It also enables the robotic arm to move the separated sprue and product to the preset sorting and collection area, reducing material misplacement caused by displacement deviation. At the same time, the drive component can flexibly adjust the robotic arm's sliding speed according to the injection molding machine's production rhythm and material transfer distance, further ensuring the stability of the overall production rhythm. In summary, this application includes at least one of the following beneficial technical effects: 1. By using the clamping component in the middle of the carrier frame and the suction component at the end, the clamping component and the suction component maintain an independent gripping state during the sliding and conveying process of the carrier frame. This allows for the simultaneous separation and conveying of the product body and the sprue material, and also enables the two to be conveyed to the corresponding collection areas according to a preset path for classification and collection. The separation and classification actions are completed simultaneously with the conveying, greatly reducing subsequent manual intervention. The operation speed can match the production cycle of the injection molding machine, effectively reducing the problem of temporary storage area accumulation caused by the lag in manual separation and chaotic classification of molded parts, thereby reducing the problem of slowing down the overall production process and effectively ensuring the continuity and efficiency of the production process. 2. The suction cup can make contact with the product body. With the help of the external air supply equipment, the negative pressure suction of the suction cup is adjusted through the first connecting pipe to ensure that the product body always maintains a stable adsorption state during the sliding and transfer of the carrier frame. There will be no displacement or falling off, which provides a reliable adsorption guarantee for the synchronous separation and classified transfer of the product body and the sprue material. 3. With its stable and controllable clamping force, the gripper cylinder can effectively reduce the slippage or deformation of sprue material during the transfer process, ensuring the reliability of sprue material gripping. At the same time, the gripper cylinder is slidably set on the second support rod, which can form a coordinated adjustment with the suction component. The position of the gripper cylinder and the suction cup can be adjusted synchronously according to the relative position of the sprue material and the product body in different product molding parts.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses an injection molded part sorting device. (Refer to...) Figure 1 A sorting device for injection molded parts includes a picking mechanism and a carrier frame 3. The picking mechanism includes a suction component 1 and a clamping component 2. The suction component 1 and the clamping component 2 are used to pick up the product body and clamp the sprue material, respectively. The carrier frame 3 is slidably arranged so that the suction component 1 and the clamping component 2 can move synchronously. First, it slides to the injection molding machine so that the suction component 1 can accurately pick up the product body and the clamping component 2 can stably clamp the sprue material. Then, the carrier frame 3 continues to slide to the corresponding position so that the picking mechanism can efficiently complete the sorting of the product body and the sprue material in the designated area.

[0029] This demonstrates that the clamping component 2 clamps the sprue material, the suction component 1 suctions the product body, and the transfer is completed in conjunction with the sliding setting of the carrier frame 3. The clamping component 2 and the suction component 1 maintain an independent gripping state during the sliding transfer process of the carrier frame 3. Not only can separation and transfer be achieved simultaneously, but the sprue material and the product body can also be transferred to the corresponding collection area according to the preset path to complete the classification and collection. Since the separation and classification actions are completed simultaneously with the transfer, the subsequent manual intervention is reduced. The operation speed can match the production cycle of the injection molding machine, effectively reducing the accumulation of molded parts in the temporary storage area due to the lag of manual separation and the confusion of classification. This reduces the occurrence of slowdown in the overall production process and ensures the continuity and efficiency of the production process.

[0030] Specifically, the support frame 3 includes multiple first support rods 31 and multiple second support rods 32. In this embodiment, there are two of each of the first support rods 31 and the second support rods 32. The second support rods 32 are fixed to the first support rods 31 and perpendicular to each other. The two first support rods 31 are parallel to each other, and the two second support rods 32 are parallel to each other.

[0031] Specifically, the suction component 1 in the material handling mechanism includes multiple suction cups 11 and multiple first connecting pipes 12. In this embodiment, referring to... Figure 2 Each suction assembly 1 is equipped with a suction cup 11 and a first connecting tube 12. The suction cup 11 is circular and has a recessed space inside. When it comes into contact with the product body and air is expelled, it can generate an adsorption force. The first connecting tube 12 is a flexible plastic tube with a certain degree of flexibility. The first connecting tube 12 is connected to an external air supply device. One end of the first connecting tube 12 is fixedly connected to and communicates with the suction cup 11, and the other end of the first connecting tube 12 is connected to an external air supply device. When the air supply device draws air, a negative pressure is formed inside the suction cup 11, thereby adsorbing the product body. In addition, there are two sets of suction assemblies 1. The two sets of suction assemblies 1 are located at both ends of the clamping assembly 2 and installed at the end of the support frame 3.

[0032] Reference Figure 3 and Figure 4 Meanwhile, a connecting component 5 is provided between the second bearing rod 32 and the suction cup 11. The connecting component 5 includes a connecting plate 51, a fastening bolt 52 and a fastening nut 53. The second bearing rod 32 is provided with a sliding groove 321. The fastening bolt 52 passes through the fastening plate and further through the sliding groove 321. The fastening nut 53 is built into the sliding groove 321 and is threadedly engaged with the fastening bolt 52. The suction nozzle is fixed to the end of the connecting plate 51 away from the fastening bolt 52.

[0033] This explains that during sliding, the fastening bolt 52 and the fastening nut 53 are loosened first. Since the fastening nut 53 is built into the sliding groove 321 of the second bearing rod 32, and the fastening bolt 52 is threadedly connected to the nut after passing through the connecting plate 51, the clamping force between the bolt and the nut is released in the loosened state. The connecting plate 51 can drive the suction cup 11 to slide freely along the extension direction of the sliding groove 321. At this time, the operator can adjust the suction cup 11 to the optimal position according to the size, shape and gripping point requirements of the product body.

[0034] During fixing, after the position of the suction cup 11 is determined, tighten the fastening bolt 52. The fastening bolt 52 and the nut in the sliding groove 321 are gradually locked through thread engagement, so that the connecting plate 51 abuts against the outer wall of the second bearing rod 32. At the same time, the nut in the sliding groove 321 forms a reverse clamping force with the groove wall of the sliding groove 321, fixing the connecting plate 51 in the current position and ensuring that the position of the suction cup 11 remains stable.

[0035] Furthermore, the clamping assembly 2 includes a gripper cylinder 21 and a second connecting pipe 22. The gripper cylinder 21 is disposed between the two sets of suction assemblies 1 and is disposed on the second bearing rod 32. The second connecting pipe 22 is also a plastic hose and is connected to an external air supply device. When the air supply device supplies air, the gripper of the gripper cylinder 21 will close, thereby clamping the sprue material.

[0036] Furthermore, the drive mechanism includes a robotic arm 6 and a drive assembly 7. The robotic arm 6 is fixedly connected to the first support rod 31. The drive assembly 7 includes a first linear module 71, a second linear module 72, and a third linear module 73. The robotic arm 6 achieves vertical sliding through the first linear module 71, the first linear module 71 achieves horizontal sliding through the second linear module 72, and the second linear module 72 achieves vertical sliding through the third linear module 73.

[0037] This explains that the robotic arm 6 achieves vertical sliding through the first linear module 71. The first linear module 71 drives the robotic arm 6 to move downwards into the injection molding machine. Then, the suction component 1 and the clamping component 2 complete the suction of the injection-molded product body and the clamping of the sprue. Subsequently, the robotic arm 6 moves upwards and disengages from the injection molding machine. Next, the third linear module 73 drives the second linear module 72, which in turn pulls the first linear module 71 and the robotic arm 6 to move together to the sorting area for the product body and the sprue. At this time, the external air supply device stops supplying air, the gripper cylinder 21 releases, and the sprue falls to the corresponding sprue sorting area. Afterwards, the second linear module 72 drives the first linear module 71, moving the robotic arm 6 to the sorting area for the product body. The external air supply device stops supplying air again, the suction cup 11 no longer generates suction force, and the product body falls to the corresponding product body sorting area, completing the entire material picking and sorting operation.

[0038] The implementation principle of the injection molded part sorting device in this application embodiment is as follows: The third linear module 73 first drives the second linear module 72, the first linear module 71, and the robotic arm 6 to adjust to the corresponding workstation side of the injection molding machine. Then, the second linear module 72 drives the first linear module 71 and the robotic arm 6 to slide horizontally to directly above the injection molding machine. Finally, the first linear module 71 drives the robotic arm 6 to move downward, so that the two sets of suction components 1 at the end of the support frame 3 are aligned with the product body, and the gripper cylinder 21 in the middle is aligned with the sprue material, until the suction cup 11 is attached to the product body and the gripper cylinder 21 is located on both sides of the sprue material. When the external air supply device is started, air is drawn from the first connecting pipe 12 of the suction component 1, creating a negative pressure inside the suction cup 11 to firmly adsorb the product body. At the same time, air is supplied to the second connecting pipe 22 of the clamping component 2, and the jaws of the gripper cylinder 21 close, stably clamping the sprue material and completing the synchronous gripping of the injection molded part. The first linear module 71 drives the robotic arm 6 to move vertically upwards, causing the support frame 3 and the gripped product body and sprue material to detach from the injection molding machine until they rise to a safe transfer height. The third linear module 73 drives the second linear module 72 to slide. The second linear module 72 drives the first linear module 71, the robotic arm 6 and the support frame 3 to slide horizontally to directly above the sprue material sorting area. At this time, the external air supply device stops supplying air to the second connecting pipe 22, the gripper cylinder 21 releases its gripper, and the sprue material naturally falls to the preset sprue material collection area. The second linear module 72 drives the first linear module 71 to slide. The first linear module 71 continues to drive the robotic arm 6 to slide to directly above the product body sorting area. The external air supply device stops pumping air to the first connecting pipe 12, the negative pressure of the suction cup 11 disappears, the product body detaches from the suction cup 11 and falls to the preset product body collection area.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
