Description

Technical Field

[0001] This utility model relates to the field of profile processing, and in particular to a profile unloading device. Background Technology

[0002] Profiles are widely used in photovoltaic frames, door and window frames, and railings. During production and processing, profiles are typically loaded into a frame. To prevent collisions and maintain surface quality, spacers are placed between layers of profiles. To improve transfer efficiency, a robotic arm is used during unloading to directly grip the spacers within the frame. The arm then moves the spacers along with multiple profiles placed on them in one go. The profiles are then placed on a conveyor belt perpendicular to them, while the spacers are stored between adjacent conveyor belts. After unloading, the stored spacers are retrieved back into the frame for reuse.

[0003] Because the spacers are located below the profiles on the conveyor belt when they are stored between the conveyor belts, the spacers can only be recycled after all the profiles on the conveyor belt have been transferred. However, the process of waiting for the profiles on the conveyor belt to be transported away, recycling the spacers, and then switching to the next basket of materials is time-consuming and may cause interruptions due to untimely connections. This is not conducive to continuous assembly line operations and thus affects the overall processing efficiency of the profiles.

[0004] The technical problem to be solved by this utility model is: how to solve the problem of discontinuous profile unloading operations, which affects the overall efficiency of profile processing. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a profile unloading device, which can shorten the time for spacer recycling and improve the overall processing efficiency of profiles.

[0006] The technical solution adopted by this utility model is: a profile unloading device, including a material frame, a separation mechanism disposed on one side of the material frame, and a transfer mechanism that reciprocates between the material frame and the separation mechanism;

[0007] The material frame is used to load profiles and material support strips. The profiles are stacked in the material frame, and the material support strips are placed between two adjacent layers of profiles. Each layer of material support strips is spaced apart along the length of the profile.

[0008] The separation mechanism includes a frame, several synchronous conveyor belts and several spacer storage racks respectively installed on the frame. Each synchronous conveyor belt is spaced apart on the top of the frame along the length of the profile. Each synchronous conveyor belt is used to support and transfer the profile. Each spacer storage rack is spaced apart along the length of the profile, and each spacer storage rack corresponds to each material support spacer.

[0009] The transfer mechanism includes a robotic arm and several auxiliary spacers. Each auxiliary spacer is spaced apart on the frame along the length of the profile. The robotic arm is equipped with several main grippers and several auxiliary grippers. Each main gripper corresponds to each material support spacer, and each auxiliary gripper corresponds to each auxiliary spacer.

[0010] In some embodiments, the frame is provided with several auxiliary brackets for supporting the auxiliary spacers, and when the auxiliary spacers are placed on the auxiliary brackets, the top of the auxiliary spacers is lower than the top of the conveyor timing belt.

[0011] In some embodiments, the auxiliary bracket is provided with a receiving groove for accommodating the auxiliary spacer, the width of the top of the receiving groove being greater than the width of the bottom.

[0012] In some implementations, the storage rack is provided with a clearance groove corresponding to the main gripper.

[0013] In some embodiments, the robotic arm also includes a gripper frame, a lifting power component, and a translational power component. Each main gripper and each auxiliary gripper is mounted on the gripper frame. The lifting power component drives the gripper frame to move up and down in the vertical direction, and the translational power component drives the gripper frame to reciprocate and move horizontally on the material frame and the machine frame.

[0014] In some embodiments, a single main gripper includes two opposing long gripping bars, a first support plate respectively disposed at the bottom of the two long gripping bars, and a first gripping power component that drives the two long gripping bars to move closer or further away. The two long gripping bars are slidably connected to the gripper frame, and the first gripping power component is mounted on the gripper frame.

[0015] A single auxiliary gripper includes two opposing short gripping rods, a second support plate respectively located at the bottom of the two short gripping rods, and a second gripping power component that drives the two short gripping rods to move closer or further away. The two short gripping rods are slidably connected to the gripper frame, the second gripping power component is mounted on the gripper frame, and the height of the first support plate is lower than that of the second support plate.

[0016] In some implementations, two main grippers are grouped together, with the two main grippers of the same group being positioned on opposite sides of the gripper frame. Two auxiliary grippers are grouped together, with the two auxiliary grippers of the same group being positioned on opposite sides of the gripper frame.

[0017] In some embodiments, the transfer mechanism further includes a truss erected above the material frame and the machine frame, a lifting power component and a translational power component mounted on the truss, a translational frame and a lifting frame provided on the truss, the translational frame and the truss being slidably connected, the translational power component and the translational frame being drive-connected, the lifting frame and the translational frame being slidably connected, the lifting power component and the lifting frame being drive-connected, and the gripper frame and the lifting frame being connected.

[0018] In some implementations, detectors are provided on both the first tray and the second tray.

[0019] In some embodiments, the material frame is provided with a number of positioning grooves corresponding to the material support strips at intervals.

[0020] The beneficial effects of this utility model are as follows: The profile unloading device of this application, by setting auxiliary spacers and secondary grippers, does not function during normal unloading operations (the secondary grippers are not working and remain open). When the main gripper transfers the last layer of material-supporting spacers and profiles in the material frame to the machine frame, the profiles fall onto the conveyor belt, and the material-supporting spacers fall into the spacer storage rack. Then, the material-supporting spacers in the spacer storage rack are retrieved, and the main gripper reaches down to the spacer storage rack to grab the bottommost material-supporting spacer. Simultaneously, the auxiliary gripper picks up the material support bar, and the robotic arm transfers the material support bar, auxiliary bar, and profiles on the conveyor belt into the material frame. Then, the main gripper releases the material support bar, allowing it to fall into the material frame. Next, the robotic arm transfers the auxiliary bar and the profiles on it back to the frame, allowing the profiles to fall onto the conveyor belt, completing the material support bar recycling operation. This shortens the material support bar recycling cycle, avoids long-term interruptions in the profile processing process, and improves the overall work efficiency of profile processing.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please see Figures 1 to 8This invention relates to a profile unloading device 100, which is the first embodiment of the present invention. Its purpose is to solve the problem of excessively long interruptions in existing profile unloading operations, affecting the continuity of assembly line operations and ultimately reducing the overall processing efficiency of profiles. The profile unloading device 100 includes a material frame 10, a separation mechanism 20 disposed on one side of the material frame 10, and a transfer mechanism that reciprocates between the material frame 10 and the separation mechanism 20. The material frame 10 is used to load profiles and material support strips 11. The profiles are stacked within the material frame 10, and the material support strips 11 are disposed between adjacent layers of profiles, with each layer of material support strips 11 spaced apart along the length of the profile. The separation mechanism 20 includes a frame 21, several synchronous conveyor belts 22 respectively mounted on the frame 21, and several material support strip storage racks 23. Each synchronous conveyor belt 22 extends along the length of the profile. The profile unloading device 100 of this application is arranged at intervals along the length of the profile on the top of the frame 21. Each synchronous conveyor belt 22 is used to support and transfer the profile. Each spacer storage rack 23 is arranged at intervals along the length of the profile, and each spacer storage rack 23 corresponds to each material support spacer 11. The transfer mechanism includes a robot arm 30 and several auxiliary spacers 40. Each auxiliary spacer 40 is arranged at intervals along the length of the profile on the frame 21. The robot arm 30 is equipped with several main grippers 31 and several auxiliary grippers 32. Each main gripper 31 corresponds to each material support spacer 11, and each auxiliary gripper 32 corresponds to each auxiliary spacer 40. The profile unloading device 100 of this application can shorten the time for spacer recycling and improve the overall processing efficiency of the profile.

[0034] like Figure 1 and Figure 2 As shown, the material frame 10 is provided with a plurality of positioning grooves 12 corresponding to the material support strips 11 at intervals. The positioning grooves 12 on the material frame 10 correspond one-to-one with the strip storage rack 23 on the frame 21. Preferably, the positioning grooves 12 and the strip storage rack 23 are on the same central axis, so that the material support strips 11 can be moved back and forth between the material frame 10 and the strip storage rack 23 by direct horizontal movement.

[0035] like Figure 3 and Figure 4 As shown, the frame 21 is provided with several auxiliary brackets 211 for supporting the auxiliary spacers 40. In order to avoid the auxiliary spacers 40 interfering with the profiles on the conveyor belt 22, when the auxiliary spacers 40 are placed on the auxiliary brackets 211, the top of the auxiliary spacers 40 is lower than the top of the conveyor belt 22.

[0036] Furthermore, the auxiliary bracket 211 is provided with a receiving groove (not shown in the figure) for accommodating the auxiliary spacer 40. The width of the top of the receiving groove is greater than the width of the bottom. By providing a receiving groove on the auxiliary bracket 211, the position of the auxiliary spacer 40 on the auxiliary bracket 211 can be limited, so that the auxiliary gripper 32 can grab or put down the auxiliary spacer 40, thereby improving the positioning accuracy. The receiving groove has a structure that is wider at the top and narrower at the bottom, which can play a guiding role, so that the auxiliary spacer 40 can be placed into the receiving groove.

[0037] Please refer to the following: Figure 3 and Figure 4 Each conveyor belt 22 is driven by a servo motor mounted on the frame. The servo motor drives each conveyor belt 22 to operate simultaneously through a transmission shaft and a chain. This ensures that each conveyor belt 22 rotates synchronously, thus ensuring that the profile does not sway due to the different speeds of each conveyor belt 22. This makes the profile conveying smoother and also saves power components.

[0038] like Figure 4 As shown, the spacer storage rack 23 has oppositely arranged side plates and oppositely arranged end plates forming a chamber for accommodating the material support spacer 11. Preferably, in order to facilitate the removal of the stored material support spacer 11 from the spacer storage rack 23, clearance grooves 231 corresponding to the main gripper 31 are provided on opposite sides of the spacer storage rack 23.

[0039] like Figure 5 and Figure 6 As shown, the robotic arm 30 also includes a gripper frame 33, a lifting power component 34, and a translational force component 35. Each main gripper 31 and each auxiliary gripper 32 are mounted on the gripper frame 33. The lifting power component 34 drives the gripper frame 33 to move up and down in the vertical direction, and the translational force component 35 drives the gripper frame 33 to reciprocate and translate on the material frame 10 and the frame 21.

[0040] Preferably, both the translational motion component 35 and the lifting motion component 34 are servo motors.

[0041] Specifically, a single main gripper 31 includes two opposing long gripping rods 311, a first support plate 313 respectively disposed at the bottom of the two long gripping rods 311, and a first gripping power component 312 for driving the two long gripping rods 311 to move closer or further away. The two long gripping rods 311 are slidably connected to the gripper frame 33, and the first gripping power component 312 is mounted on the gripper frame 33.

[0042] Each auxiliary gripper 32 includes two opposing short gripping rods 321, a second support plate 323 respectively disposed at the bottom of the two short gripping rods 321, and a second gripping power component 322 for driving the two short gripping rods 321 closer to or further away from each other. The two short gripping rods 321 are slidably connected to the gripper frame 33. The second gripping power component 322 is mounted on the gripper frame 33. The height of the first support plate 313 is lower than that of the second support plate 323. This arrangement can prevent interference between the gripping material spacer 11 and the auxiliary spacer 40 when the material spacer 11 is being gripped simultaneously.

[0043] The main gripper 31 and the auxiliary gripper 32 with the above structure can grasp the spacer bar by lifting it, which can prevent the spacer bar from deforming and thus prevent the profile from rolling on the spacer bar due to deformation, making the transfer of the spacer bar and the profile bar more stable.

[0044] In this embodiment, both the first gripping power component 312 and the second gripping power component 322 are cylinders, and each long gripping rod 311 corresponds to one first gripping power component 312, and each short gripping rod 321 corresponds to one second gripping power component 322. In other embodiments, other power components that can achieve the same function can also be used as the first gripping power component 312 and the second gripping power component 322, such as hydraulic cylinders, electric actuators, or motors.

[0045] Preferably, both the first tray 313 and the second tray 323 are equipped with detectors, which are used to detect whether the trays correspond to the spacers, thereby improving the accuracy of gripping. Optionally, the detectors on the first tray 313 and the second tray 323 are through-beam sensors.

[0046] To ensure balanced force when gripping the spacer bar, two main grippers 31 are grouped together, with the two main grippers 31 in the same group positioned on opposite sides of the gripper frame 33. When gripping the material support spacer bar 11, the two main grippers 31 on both sides grip both ends of the material support spacer bar 11. Similarly, two auxiliary grippers 32 are grouped together, with the two auxiliary grippers 32 in the same group positioned on opposite sides of the gripper frame 33. When gripping the auxiliary spacer bar 40, the two auxiliary grippers 32 on both sides grip both ends of the auxiliary spacer bar 40.

[0047] To facilitate the installation of the robotic arm 30, the transfer mechanism also includes a truss 50 erected above the material frame 10 and the frame 21. The lifting power component 34 and the translational power component 35 are installed on the truss 50. The truss 50 is provided with a translation frame 51 and a lifting frame 52. The translation frame 51 is slidably connected to the truss 50. The translational power component 35 is drivenly connected to the translation frame 51. The lifting frame 52 is slidably connected to the translation frame 51. The lifting power component 34 is drivenly connected to the lifting frame 52. The gripper frame 33 is connected to the lifting frame 52.

[0048] Specifically, a first guide rail is provided on the truss 50, and a first slider that slides with the first guide rail is provided on the translation frame 51. Similarly, a second guide rail is provided on the lifting frame 52, and a second slider that slides with the second guide rail is provided on the translation frame 51.

[0049] The profile unloading device 100 of this application, by setting an auxiliary partition 40 and a secondary gripper 32, does not function during normal unloading operations. The secondary gripper 32 remains open. When the main gripper 31 transfers the last layer of material support partition 11 and profile in the material frame 10 to the frame 21, the profile falls onto the conveyor belt 22, and the material support partition 11 falls into the partition storage rack 23. Then, the material support partition 11 in the partition storage rack 23 is retrieved. The main gripper 31 reaches down to the partition storage rack 23 to grab the bottommost material support partition 11, while the secondary gripper... The robot arm 30 picks up the auxiliary spacer 40 and transfers the material support spacer 11, the auxiliary spacer 40, and the profile on the conveyor belt 22 together into the material frame 10. Then, the main gripper 31 releases the material support spacer 11 so that it falls into the material frame 10. Next, the robot arm 30 transfers the auxiliary spacer 40 and the profile on it back to the frame 21 so that the profile falls onto the conveyor belt 22, completing the recovery operation of the material support spacer 11. This shortens the recovery cycle of the material support spacer 11, avoids long-term interruptions in the profile processing, and improves the overall work efficiency of profile processing.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
