Description

Technical Field

[0001] This utility model relates to the field of profile conveying and palletizing technology, specifically to a conveying, gripping and transferring mechanism for an L-profile palletizing machine. Background Technology

[0002] After L-shaped profiles are processed, they need to be stored. Sometimes, due to their length and weight, manual handling and stacking are not only inefficient but also extremely labor-intensive. Therefore, people use palletizers for automatic stacking. However, existing palletizers often stack one by one, using robotic arms to place each profile onto a palletizing tray. But to ensure the stability of the stacking, manual adjustments to the lower layer are required when continuing to stack on the upper layer, which is very troublesome. Therefore, it is particularly important to design a conveying, gripping, and transferring mechanism for L-shaped profile palletizers to solve the above problems. Summary of the Invention

[0003] To solve the above problems, this utility model designs a conveying, gripping, and transferring mechanism for an L-shaped profile palletizing machine. The profiles can be arranged by themselves through belt pulley conveying and L-shaped stops. The design of the transfer robotic arm assembly and the robotic arm translation mechanism can stack the arranged profiles as a whole without manual adjustment, and can continue to stack the upper layer without increasing the practicality.

[0004] To solve the above-mentioned technical problems, this utility model provides a conveying, gripping, and transferring mechanism for an L-shaped profile palletizer. The mechanism includes a main frame, a transfer robotic arm assembly, a robotic arm translation mechanism, and a robotic arm lifting mechanism. The main frame is internally divided into two areas: a palletizing temporary storage area and a paper-pulling and palletizing placement area. A pulley conveyor is installed in the palletizing temporary storage area, positioned front to back with an L-shaped stop at its rear end. A support base is located on the top of the main frame, connected to the top of the main frame via the robotic arm translation mechanism. The robotic arm lifting mechanism is vertically mounted on the top of the support base, with its output shaft passing through the support base and extending into the main frame to connect with the horizontally positioned transfer robotic arm assembly. The transfer robotic arm assembly reciprocates above the palletizing temporary storage area and the paper-pulling and palletizing placement area via the robotic arm translation mechanism.

[0005] Furthermore, the lifting mechanism of the robotic arm is a cylinder assembly with adjustable lifting height. The cylinder assembly is vertically fixed on the support base, and the output shaft end of the cylinder assembly passes through the support base, extends into the main frame, and is connected to the top of the transfer robotic arm assembly through a connector.

[0006] Furthermore, the transfer robotic arm assembly includes a horizontally arranged robotic arm body, a clamping plate assembly, a servo motor, a first gear transmission assembly, a clamping screw, and a clamping screw nut assembly. The output shaft end of the cylinder assembly extends into the main frame and is connected to the center of the top of the robotic arm body via a connector. The robotic arm body is placed left and right, and a clamping plate assembly is connected to the bottom of each end. A second slide rail is provided at the bottom of both ends of the robotic arm body. The clamping plate assembly is connected to the second slide rail via a slide groove provided at the top. The servo motor is installed in the middle section of the bottom of the robotic arm body. The output shaft of the servo motor is connected to two clamping screws via the first gear transmission assembly. The two clamping screws are arranged in a straight line and are rotatably connected to the bottom of both ends of the robotic arm body. The clamping plate assemblies on both sides are connected to the two clamping screws via the clamping screw nut assembly, and the threads on the two clamping screws are arranged in opposite directions.

[0007] Furthermore, the translation mechanism includes a translation servo motor, a second gear transmission assembly, a main shaft, a drive gear, a rack structure, and a first slide rail. The rack structure and the first slide rail are positioned front to back and fixed on the top of the main frame. The support base is slidably connected to the first slide rail via a slider located at the bottom. The translation servo motor is fixed on the support base and is connected to the main shaft via the second gear transmission assembly. The lower end of the main shaft passes through the support base and is fitted with a drive gear, which meshes with the rack structure.

[0008] Furthermore, a photoelectric sensor assembly is also installed on the main support on one side of the pulley conveyor. The photoelectric sensor assembly consists of two photoelectric sensors placed one in front of the other.

[0009] With the above structure, this utility model can arrange the profiles by means of belt pulley conveying and L-shaped stop blocks. The arrangement of the profiles can be stacked as a whole through the design of the transfer robotic arm assembly and the robotic arm translation mechanism. The upper layer can be stacked without manual adjustment, which increases the practicality. Moreover, this utility model also has the advantages of simple stacking, convenient use and high efficiency. Attached Figure Description

[0020] The present invention will be further described in detail below through specific embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3The conveying and gripping transfer mechanism for an L-shaped profile palletizer shown includes a main frame 1, a transfer robotic arm assembly, a robotic arm translation mechanism, and a robotic arm lifting mechanism. The main frame 1 is divided into two areas: a front and a rear, which are respectively a palletizing temporary storage area and a paper-pulling and palletizing placement area. A belt conveyor 2 is installed in the palletizing temporary storage area. The belt conveyor is placed front and rear, and an L-shaped stop 3 is installed at its rear end. A support base 4 is installed on the top of the main frame. The support base is connected to the top of the main frame through the robotic arm translation mechanism. The robotic arm lifting mechanism is vertically installed on the top of the support base. Its output shaft end passes through the support base and extends into the main frame to connect with the horizontally placed transfer robotic arm assembly. The transfer robotic arm assembly reciprocates above the palletizing temporary storage area and the paper-pulling and palletizing placement area through the robotic arm translation mechanism. This invention uses a belt pulley conveyor in conjunction with an L-shaped stop to allow the profiles to arrange themselves. The design of the transfer robotic arm assembly and the robotic arm translation mechanism allows the arranged profiles to be stacked as a whole without manual adjustment, thus increasing practicality. Moreover, this invention also has the advantages of simple stacking, convenient use, and high efficiency.

[0022] like Figure 3 The lifting mechanism of the robotic arm shown is a cylinder assembly 5 with adjustable lifting height. The cylinder assembly is vertically fixed on the support base, and the output shaft end of the cylinder assembly passes through the support base, extends into the main frame, and is connected to the top of the transfer robotic arm assembly via connector 18. This utility model uses the cylinder assembly to drive the transfer robotic arm assembly to complete the overall grasping and placement of the profile.

[0023] like Figure 3 and Figure 5The shown transfer robotic arm assembly includes a horizontally arranged robotic arm body 6, a clamping plate assembly 7, a servo motor 8, a first gear transmission assembly 9, a clamping screw 10, and a clamping screw nut assembly. The clamping plate assembly is a long strip placed horizontally front to back. The output shaft end of the cylinder assembly extends into the main frame and is connected to the center of the top of the robotic arm body through a connector. The robotic arm body is placed left to right, and a clamping plate assembly is connected to the bottom of each end. A second slide rail 11 is provided at the bottom of both ends of the robotic arm body. The clamping plate assembly is connected to the second slide rail through a slide groove provided at the top. The servo motor is installed in the middle section of the bottom of the robotic arm body. The output shaft of the servo motor is connected to two clamping screws through the first gear transmission assembly. The two clamping screws are arranged in a straight line and are rotatably connected to the bottom of both ends of the robotic arm body. The clamping plate assemblies on both sides are connected to the two clamping screws through the clamping screw nut assembly, and the threads on the two clamping screws are arranged in opposite directions. During operation, the cylinder assembly is first activated by the PLC controller to lower the workpiece. Then, the servo motor is started to rotate the two clamping screws. The clamping plate assemblies on both sides move towards each other to clamp the workpiece under the cooperation of the rotating clamping screws and clamping screw nut assemblies. After clamping, the lifting cylinder assembly is used to raise the workpiece. Then, the translation mechanism is activated to move the handling robotic arm assembly with the workpiece. After translation, the workpiece continues to lower and is placed on the movable tray in the paper palletizing area.

[0024] like Figure 4 The translation mechanism shown includes a translation servo motor, a second gear transmission assembly 12, a main shaft 13, a drive gear 14, a rack structure 15, and a first slide rail 16. The rack structure and the first slide rail are positioned front-to-back and fixed to the top of the main frame. A support base is slidably connected to the first slide rail via a slider 17 located at the bottom. The translation servo motor is fixed to the support base and connected to the main shaft via the second gear transmission assembly. The lower end of the main shaft passes through the support base and is fitted with a drive gear, which meshes with the rack structure. In this invention, the translation servo motor drives the drive gear to rotate. Since the rack structure is stationary, the rotating drive gear, under the action of the meshing rack structure, moves the support base along the first slide rail.

[0025] A photoelectric sensor assembly is also installed on the main support on one side of the aforementioned pulley conveyor. The photoelectric sensor assembly consists of two photoelectric sensors placed one in front of the other. When both photoelectric sensors detect the profile simultaneously, the robotic arm lifting mechanism is activated to grab it. This design allows for real-time monitoring of whether the number of profiles arranged on the pulley conveyor meets the requirements for overall stacking.

[0026] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
