Description

Technical Field

[0001] This utility model belongs to the field of robotic arm technology, and in particular relates to a robotic arm with a cooling structure. Background Technology

[0002] Injection molding is a molding method that combines injection and molding. At a certain temperature, plastic material that has been completely melted by a screw is injected into a mold cavity under high pressure. After cooling and solidification, a molded product is obtained. After injection molding, the workpiece needs to be transferred and unloaded by a robot.

[0003] Existing injection molding robots are prone to deformation during workpiece transfer due to the high surface temperature of the workpiece immediately after injection molding. Therefore, we propose a robot with a cooling structure. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a robotic arm with a cooling structure, thereby preventing workpiece deformation during transport.

[0005] In view of this, the present invention provides a robotic arm with a cooling structure, including a working frame, a transfer frame fixedly connected to the inner wall of the working frame, a transfer motor fixedly connected to one end of the transfer frame, a transfer belt fixedly connected to the output end of the transfer motor, a transfer base fixedly connected to the outer wall of the transfer belt, a transfer guide rail provided at the connection between the transfer base and the transfer frame, a mounting base fixedly connected to the outer wall of the transfer base, a cooling perforated plate fixedly connected to the outer wall of the mounting base, cooling heads provided in the holes of the cooling perforated plate, a refrigeration assembly provided at the bottom end of the transfer frame, a transfer plate fixedly connected to the outer wall of the cooling perforated plate, and a transfer column fixedly connected to the outer wall of the transfer plate.

[0006] Based on the above structure, the sliding of the transfer base drives the transfer plate on the outer wall of the mounting base to slide synchronously, thereby transferring the injection molded workpiece from inside the injection molding machine through the transfer column. At the same time, the cooling component works to cool the transfer column on the outer wall of the transfer plate through the cooling head. The temperature of the transfer column decreases, thereby cooling the injection molded workpiece, realizing the cooling and transfer operation of the injection molded workpiece.

[0007] Preferably, the mounting base forms a horizontal sliding structure with the transfer belt and the transfer base and the transfer guide rail. In this embodiment, it is convenient for the transfer motor to work so that the transfer base can slide horizontally along the outer wall of the transfer guide rail through the transfer belt. The sliding of the transfer base causes the transfer plate on the outer wall of the mounting base to slide synchronously, so as to realize the reciprocating sliding operation of the transfer plate.

[0008] Preferably, the cooling heads are arranged in a rectangular array along the shape of the cooling perforated plate. In this embodiment, this facilitates the operation of the cooling assembly by cooling the transfer columns on the outer wall of the transfer plate through the cooling heads. The temperature of the transfer columns is reduced, thereby uniformly cooling the injection molded workpiece.

[0009] Preferably, the transfer columns are perpendicular to the transfer plate and are equidistantly distributed along the outer wall of the transfer plate. In this embodiment, it is beneficial to transfer the injection molded workpiece to the transfer columns on the outer wall of the transfer plate by the ejector pin, thus avoiding the injection molded workpiece from falling off.

[0010] Preferably, a feeding frame is fixedly connected to the top of the inner working frame, a feeding motor is fixedly connected to the bottom of the feeding frame, a feeding belt is provided at the output end of the feeding motor, a bracket is fixedly connected to the outer wall of the feeding belt, a feeding guide rail is provided at the connection between the bracket and the feeding frame, a flipping motor is fixedly connected to the outer wall of the bracket, a flipping seat is fixedly connected to the output end of the flipping motor, a flipping frame is fixedly connected to the outer wall of the flipping seat, a suction cup is fixedly connected to the outer wall of the flipping frame, and a feeding platform is provided below the suction cup. In this embodiment, the bracket slides to drive the suction cup on the outer wall of the flipping frame to come into contact with the injection molded workpiece on the outer wall of the transfer column. The suction cup uses negative pressure to detach the injection molded workpiece from the transfer column and move it away. Then, the flipping motor works to drive the flipping frame on the outer wall of the flipping seat to flip to a horizontal state. Then, the suction cup stops working, and the injection molded workpiece falls onto the feeding platform by its own gravity, realizing the feeding operation of the injection molded workpiece.

[0011] Preferably, the bracket is T-shaped, and the bracket forms a sliding structure with the feeding belt and the feeding guide rail. The feeding guide rail is perpendicular to the transfer guide rail. In this embodiment, by setting the bracket in a T-shape, it is beneficial to improve the structural strength of the bracket and facilitate the operation of the feeding motor to drive the bracket to slide back and forth along the outer wall of the feeding guide rail via the feeding belt.

[0012] Preferably, the flipping frame is parallel to the transfer plate, and the suction cups correspond one-to-one with the transfer columns. In this embodiment, it is convenient for the bracket to slide and drive the suction cups on the outer wall of the flipping frame to fit against the injection molded workpieces on the outer wall of the transfer columns. The suction cups use negative pressure to detach the injection molded workpieces from the transfer columns and move them away, thereby realizing the rapid unloading operation of the injection molded workpieces.

[0013] The beneficial effects of this utility model are:

[0014] 1. This robotic arm with a cooling structure, by setting a cooling head, causes the transfer base to slide synchronously, driving the transfer plate on the outer wall of the mounting base to slide, and then transfers the injection molded workpiece from inside the injection molding machine through the transfer column. At the same time, the cooling component works to cool the transfer column on the outer wall of the transfer plate through the cooling head. The temperature of the transfer column decreases, thereby cooling the injection molded workpiece, realizing the cooling and transfer operation of the injection molded workpiece.

[0015] 2. This robotic arm with a cooling structure uses a rotating frame. The support slides to bring the suction cup on the outer wall of the rotating frame into contact with the injection molded workpiece on the outer wall of the transfer column. The suction cup uses negative pressure to detach the injection molded workpiece from the transfer column and move it away. Then, the rotating motor drives the rotating frame on the outer wall of the rotating seat to rotate to a horizontal state. Then, the suction cup stops working, and the injection molded workpiece falls onto the unloading platform by its own gravity, thus realizing the unloading operation of the injection molded workpiece.

[0025] This application discloses a robotic arm with a cooling structure, including a working frame 1. A transfer frame 2 is fixedly connected to the inner wall of the working frame 1. A transfer motor 3 is fixedly connected to one end of the transfer frame 2. A transfer belt 4 is fixedly connected to the output end of the transfer motor 3. A transfer base 5 is fixedly connected to the outer wall of the transfer belt 4. A transfer guide rail 6 is provided at the connection between the transfer base 5 and the transfer frame 2. A mounting base 7 is fixedly connected to the outer wall of the transfer base 5. A cooling perforated plate 8 is fixedly connected to the outer wall of the mounting base 7. A cooling head 9 is provided in the holes of the cooling perforated plate 8. A cooling component 10 is provided at the bottom end of the transfer frame 2. A transfer plate 11 is fixedly connected to the outer wall of the cooling perforated plate 8. A transfer column 1101 is fixedly connected to the outer wall of the transfer plate 11.

[0026] Based on the above structure, the sliding base 5 drives the sliding plate 11 on the outer wall of the mounting base 7 to slide synchronously, thereby transferring the injection molded workpiece from the injection molding machine through the transfer column 1101. At the same time, the cooling component 10 works to cool the transfer column 1101 on the outer wall of the transfer plate 11 through the cooling head 9. The temperature of the transfer column 1101 decreases, thereby cooling the injection molded workpiece and realizing the cooling and transfer operation of the injection molded workpiece.

[0027] In one embodiment, the mounting base 7 forms a horizontal sliding structure with the transfer belt 4 and the transfer base 5 and the transfer guide rail 6.

[0028] In this embodiment, the transfer motor 3 drives the transfer base 5 to slide horizontally along the outer wall of the transfer guide rail 6 via the transfer belt 4. The sliding of the transfer base 5 drives the transfer plate 11 on the outer wall of the mounting base 7 to slide synchronously, thereby realizing the reciprocating sliding operation of the transfer plate 11.

[0029] In one embodiment, the cooling heads 9 are arranged in a rectangular array along the shape of the cooling perforated plate 8.

[0030] In this embodiment, to facilitate the operation of the cooling component 10, the cooling head 9 cools the transfer column 1101 on the outer wall of the transfer plate 11, thereby reducing the temperature of the transfer column 1101 and uniformly cooling the injection molded workpiece.

[0031] In one embodiment, the transfer column 1101 is perpendicular to the transfer plate 11, and the transfer column 1101 is equidistantly distributed along the outer wall of the transfer plate 11.

[0032] In this embodiment, it is advantageous to transfer the injection molded workpiece to the transfer column 1101 on the outer wall of the transfer plate 11 by the ejector pin, thereby preventing the injection molded workpiece from falling off.

[0033] In one embodiment, a feeding frame 12 is fixedly connected to the top of the inner part of the working frame 1, a feeding motor 13 is fixedly connected to the bottom of the feeding frame 12, a feeding belt 14 is provided at the output end of the feeding motor 13, a bracket 15 is fixedly connected to the outer wall of the feeding belt 14, a feeding guide rail 16 is provided at the connection between the bracket 15 and the feeding frame 12, a flipping motor 17 is fixedly connected to the outer wall of the bracket 15, a flipping seat 18 is fixedly connected to the output end of the flipping motor 17, a flipping frame 19 is fixedly connected to the outer wall of the flipping seat 18, a suction cup 20 is fixedly connected to the outer wall of the flipping frame 19, and a feeding platform 21 is provided below the suction cup 20.

[0034] In this embodiment, the bracket 15 slides to cause the suction cup 20 on the outer wall of the flipping frame 19 to come into contact with the injection molded workpiece on the outer wall of the transfer column 1101. The suction cup 20 uses negative pressure to detach the injection molded workpiece from the transfer column 1101 and move it away. Then, the flipping motor 17 works to drive the flipping frame 19 on the outer wall of the flipping seat 18 to flip to a horizontal state. Then, the suction cup 20 stops working, and the injection molded workpiece falls onto the unloading platform 21 by its own gravity, realizing the unloading operation of the injection molded workpiece.

[0035] In one embodiment, the bracket 15 is T-shaped and forms a sliding structure between the bracket 15 and the feeding guide rail 16 via the feeding belt 14. The feeding guide rail 16 is perpendicular to the transfer guide rail 6.

[0036] In this embodiment, by setting a "T"-shaped bracket 15, it is beneficial to improve the structural strength of the bracket 15 and facilitate the operation of the feeding motor 13, which drives the bracket 15 to slide back and forth along the outer wall of the feeding guide rail 16 via the feeding belt 14.

[0037] In one embodiment, the flipping frame 19 is parallel to the transfer plate 11, and the suction cups 20 correspond one-to-one with the transfer columns 1101.

[0038] In this embodiment, the suction cup 20 on the outer wall of the rotating frame 19 is slidably driven by the bracket 15 to fit against the injection molded workpiece on the outer wall of the transfer column 1101. The suction cup 20 uses negative pressure to detach the injection molded workpiece from the transfer column 1101 and move it away, thereby realizing the rapid unloading operation of the injection molded workpiece.

[0039] In this embodiment, the robotic arm with a cooling structure operates as follows: First, the workpiece is injection molded by an injection molding machine. Then, the injection molded workpiece is transferred to the transfer column 1101 on the outer wall of the transfer plate 11 by an ejector pin. Next, the transfer motor 3 operates, driving the transfer base 5 to slide horizontally along the outer wall of the transfer guide rail 6 via the transfer belt 4. The sliding of the transfer base 5 causes the transfer plate 11 on the outer wall of the mounting base 7 to slide synchronously, thereby transferring the injection molded workpiece from inside the injection molding machine via the transfer column 1101. At the same time, the cooling component 10 operates, cooling the transfer column 1101 on the outer wall of the transfer plate 11 through the cooling head 9. The temperature of the transfer column 1101 decreases, thereby cooling the injection molded workpiece, realizing the cooling and transfer operation of the injection molded workpiece.

[0040] Next, when the transfer plate 11 moves to one side of the flipping frame 19, the unloading motor 13 operates and drives the bracket 15 to slide back and forth along the outer wall of the unloading guide rail 16 via the unloading belt 14. The sliding of the bracket 15 causes the suction cup 20 on the outer wall of the flipping frame 19 to come into contact with the injection molded workpiece on the outer wall of the transfer column 1101. The suction cup 20 uses negative pressure to detach the injection molded workpiece from the transfer column 1101 and move it away. Then, the flipping motor 17 operates and drives the flipping frame 19 on the outer wall of the flipping seat 18 to flip to a horizontal state. Then, the suction cup 20 stops working, and the injection molded workpiece falls onto the unloading table 21 by its own gravity, realizing the unloading operation of the injection molded workpiece.
