Description

Technical Field

[0001] This utility model relates to the field of packaging production line technology, specifically to an assembly control system for washing machine drum parts. Background Technology

[0002] In the production of washing machine drum parts, the assembly process is extremely critical. Currently, the assembly of most washing machine drum parts relies on manual operation. For large components, manual assembly is inefficient and it is difficult to guarantee assembly accuracy. Furthermore, prolonged manual work can lead to fatigue, further reducing assembly quality and efficiency. With the development of industrial automation, those skilled in the art are constantly exploring improvements. For example, Chinese Patent Publication No. CN207087435U discloses a robotic arm for molding plastic parts for washing machine drums, which achieves positioning by locating from the center hole of the drum plastic part, combined with internal contact and external clamping. However, for washing machine drum parts with specific structures and assembly requirements, existing solutions still have shortcomings, lacking an efficient and precise assembly control system to meet the needs of large-scale production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an assembly control system for washing machine drum parts.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An assembly control system for washing machine drum parts includes a production line and drum parts placed on the production line. An inclined slide is provided at the inlet end of the production line, and a robot arm is provided at the inlet end of the production line.

[0006] The roller part is cylindrical in shape, with four vertical ridges on its outer side wall and a positioning post in the middle of its bottom.

[0007] The assembly line has side guards on both sides and a motor for driving the assembly line is located on its side.

[0008] The inclined slide is curved and its bottom connects to the inlet of the production line;

[0009] The robotic arm has a drive mechanism installed at its end. Each end of the drive mechanism is equipped with a gripping mechanism, and a camera is positioned between the gripping mechanisms. The camera is positioned facing the positioning post of the roller part. The drive mechanism drives the gripping mechanism to contact the outer wall between the four edges, and the assembly is performed under the action of the robotic arm.

[0010] This technical solution uses a combination of an assembly line and an inclined slide to deliver the washing machine drum parts to a robotic arm. The robotic arm integrates a camera and a clamping mechanism. The camera captures the positioning pins of the drum parts, and the clamping mechanism moves to the outer wall of the drum parts and clamps them, thereby improving the assembly efficiency of large components. Specifically, the inclined slide is at a certain angle, allowing the roller parts produced in the previous process to slide down to the entrance of the production line by gravity. A motor is installed on the side of the production line, driving the conveyor belt to circulate. The side of the conveyor belt is equipped with guards, some of which are designed to accommodate missing edges for the removal process. The production line conveys the parts forward at a certain speed, while a robotic arm is located at the exit of the production line. The robotic arm is a six-degree-of-freedom robotic arm that can move freely between the production line and the assembly line. The improvement lies in the tooling at the end of the robotic arm. The tooling consists of three parts: a camera, a clamping mechanism, and a drive mechanism. The camera transmits the captured images to the controller on the robotic arm, thereby detecting the positioning post of the roller part. With the positioning post as the center and the diameter of the roller part known, the drive mechanism drives the clamping mechanism to expand to both sides, which can accommodate roller parts of different diameters. This allows for quick positioning and clamping of the roller parts, and then assembly according to the specified positions. It should be noted that this utility model only improves the structural hardware; the controller uses conventional programs, and this utility model does not make any improvements to the software, thus meeting the protection requirements of a utility model.

[0011] In addition, the assembly control system for the washing machine drum parts proposed above according to this utility model may also have the following additional technical features:

[0012] According to one embodiment of the present invention, the motor drives the belt on the production line to rotate in a cycle, and the side flanges on both sides of the belt are provided with notches, and the notches are provided with rejection stations.

[0013] According to one embodiment of the present invention, the camera is a high-resolution industrial camera that acquires images of the positioning columns inside the roller part in real time.

[0014] According to one embodiment of the present invention, the driving mechanism includes a driving motor and driving rods located on both sides of the driving motor, and a clamping mechanism is located on the driving rods on both sides.

[0015] According to one embodiment of the present invention, the clamping mechanism is a clamp with silicone on the inner side. The clamp moves in a telescopic motion under the drive mechanism. The two clamps respectively span the diameter of the roller part and clamp between the four edges of the outer wall.

[0016] According to one embodiment of the present invention, the robotic arm has a built-in controller. The input end of the controller is connected to the camera, and the output end of the controller is connected to the robotic arm, the drive mechanism, and the clamping mechanism respectively via a bus.

[0017] According to one embodiment of the present invention, the robotic arm is a six-degree-of-freedom robotic arm, which is fixed to one side of the outlet end of the production line by a bracket.

[0018] According to one embodiment of the present invention, the controller is an Omron PLC control device, which controls the maximum speed of the robot arm, enabling it to grasp at least 20 roller parts per minute.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] By combining the assembly line with the inclined slide, the washing machine drum parts are delivered to the robotic arm. The robotic arm integrates a camera and a clamping mechanism. The camera captures the positioning pins of the drum parts, and the clamping mechanism moves to the outer wall of the drum parts and clamps them, thereby improving the assembly efficiency of large parts.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1 As shown, this embodiment provides an assembly control system for a washing machine drum part 3, including a production line 2 and a drum part 3 placed on the production line 2. An inclined slide 1 is provided at the inlet end of the production line 2, and a robot arm 4 is provided at the inlet end of the production line 2.

[0026] Roller part 3 is cylindrical in shape, with four vertical ridges on its outer side wall and a positioning post in the middle of its bottom.

[0027] Production line 2 has side guards on both sides and a motor for driving production line 2 is installed on its side;

[0028] Inclined slide 1, which is arc-shaped, has its bottom connected to the inlet of the flow line 2;

[0029] The robotic arm 4 has a drive mechanism 5 installed at its end. The two ends of the drive mechanism 5 are respectively provided with clamping mechanisms 6, and a camera 7 is provided between the clamping mechanisms 6. The camera 7 is positioned facing the positioning post of the roller part 3. The drive mechanism 5 drives the clamping mechanism 6 to contact the outer wall between the four edges, and the assembly is carried out under the drive of the robotic arm 4.

[0030] This technical solution uses the cooperation of the assembly line 2 and the inclined slide 1 to send the washing machine drum part 3 to the robot arm 4. The robot arm 4 integrates a camera 7 and a clamping mechanism 6. The camera 7 captures the positioning post of the drum part 3, and the clamping mechanism 6 is moved to the outer side wall of the drum part 3 and clamped, thereby improving the assembly efficiency of large parts. Specifically, the inclined slide 1 is at a certain angle, allowing the roller parts 3 produced in the previous process to slide down to the inlet of the assembly line 2 by gravity. A motor is installed on the side of the assembly line 2, which drives the belt of the assembly line 2 to circulate. The side of the belt is equipped with a guard, and some of the guards are equipped with missing edges for the installation and rejection process. The assembly line 2 conveys forward at a certain speed, while the robot arm 4 is located at the outlet of the assembly line 2. The robot arm 4 is a six-degree-of-freedom robotic arm that can move freely between the assembly line 2 and the assembly line. The improvement lies in the tooling at the end of the robot arm 4. The tooling consists of three parts: a camera 7, a clamping mechanism 6, and a drive mechanism 5. The camera 7 transmits the captured images to the controller built into the robot arm 4, thereby detecting the positioning post of the roller part 3. With the positioning post as the center and the diameter of the roller part 3 known, the drive mechanism 5 drives the clamping mechanism 6 to expand to both sides, which can accommodate roller parts 3 of different diameters, thereby quickly positioning and clamping the roller part 3 and assembling it according to the specified position. It should be noted that this utility model only improves the structural hardware; the controller uses conventional programs, and this utility model does not make any improvements to the software, thus meeting the protection requirements of a utility model.

[0031] In addition, the assembly control system for the washing machine drum part 3 proposed above according to this utility model may also have the following additional technical features:

[0032] According to one embodiment of the present invention, the motor drives the belt on the production line 2 to rotate in a cycle, and the side flanges on both sides of the belt are provided with notches, and the notches are provided with rejection stations.

[0033] In this technical solution, the rejection station includes a rejection mechanism and a rejection line 2. The rejection mechanism drives the roller parts 3 on the line 2 to move towards the rejection line 2 by driving the rejection rod, and performs rework on the defective roller parts 3.

[0034] According to one embodiment of the present invention, the camera 7 is a high-resolution industrial camera that acquires images of the positioning column inside the roller part 3 in real time.

[0035] In this technical solution, the industrial camera transmits the high-resolution images it acquires to the controller, which then detects the positioning column information of the roller part 3 through the high-resolution images; the controller is connected to the server via a cable.

[0036] According to one embodiment of the present invention, the driving mechanism 5 includes a driving motor and driving rods located on both sides of the driving motor, and the clamping mechanism 6 is located on the driving rods on both sides.

[0037] In this technical solution, the drive motor is a servo motor, and the force applied by the clamping mechanism 6 to the roller part 3 ensures that the roller part 3 can be lifted by friction without being squeezed and deformed.

[0038] According to one embodiment of the present invention, the clamping mechanism 6 is a clamp with silicone on the inner side. The clamp moves in a telescopic motion under the drive mechanism 5. The two clamps respectively cross the diameter of the roller part 3 and are clamped between the four edges of the outer wall.

[0039] In this technical solution, the roller part 3 has four equally spaced edges. The gripper needs to avoid these four edges to prevent it from gripping the edges and causing instability and falling. The positioning post has a certain protrusion. The position of the positioning post is detected and the position of the edge is indirectly determined. The robot arm 4 adjusts the clamping angle of the clamping mechanism 6 in advance.

[0040] According to one embodiment of the present invention, the robotic arm 4 has a built-in controller. The input end of the controller is connected to the camera 7, and the output end of the controller is connected to the robotic arm 4, the drive mechanism 5, and the clamping mechanism 6 via a bus.

[0041] According to one embodiment of the present invention, the robotic arm 4 is a six-degree-of-freedom robotic arm, which is fixed to one side of the outlet end of the production line 2 by a bracket.

[0042] According to one embodiment of the present invention, the controller is an Omron PLC control device, which controls the maximum speed of the robot arm 4, enabling it to grasp at least 20 roller parts 3 per minute.

[0043] The usage process of the above embodiments is as follows:

[0044] The inclined slide 1 uses gravity to slide the roller part 3 from the previous process to the inlet of the production line 2. The motor of the production line 2 drives the belt to circulate. The side guards prevent the parts from falling, and some side guards have notches to connect to the rejection station. The roller part 3 is conveyed to the robot arm 4 by the production line 2. The robot arm 4 is a six-degree-of-freedom robotic arm. The end effector includes a camera 7, a clamping mechanism 6 and a drive mechanism 5. The camera 7 captures the image of the positioning post and transmits it to the controller. The controller controls the drive mechanism 5 to drive the clamping mechanism 6 to expand to both sides with the positioning post as the center, adapting to parts of different diameters and clamping them on the outer wall between the four edges. Then, the robot arm 4 clamps the roller part 3 to the designated position for assembly.

[0045] In addition, the drive mechanism 5 uses a servo motor and drive rod to ensure appropriate clamping force; the clamping mechanism 6 has a gripper with silicone on the inside to avoid the edges when clamping; the robot arm 4 has a built-in controller that is connected to the camera 7, the robot arm 4, the drive mechanism 5, and the clamping mechanism 6. It uses an Omron PLC control device to control the maximum speed of the robot arm 4 to ensure efficient assembly.

Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope of the claims.
