Description

Technical Field

[0001] This utility model belongs to the field of assembly technology, specifically relating to a panel assembly device. Background Technology

[0002] The outdoor unit panel consists of sheet metal painted parts, injection molded parts, and screws. Assembly is done manually, requiring adjustment of the sheet metal painted parts' orientation, rotation and installation of the injection molded grille, and finally, screw tightening. Because the grille needs to fit tightly against the sheet metal painted parts after assembly to prevent noise from collisions during compressor operation, the installation requires significant force and is a continuous process, easily causing hand and wrist pain. Furthermore, manual visual inspection after prolonged continuous work can lead to fatigue and oversights, resulting in parts without tightened screws being moved to the next process.

They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0020] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used here to describe the spatial positional relationship of a device or feature as shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation of the device as described in the figure.

[0021] See also Figures 1 to 13 As shown, according to an embodiment of the present invention, a panel assembly device 3 is provided, which includes a grille positioning device 1, a conveying device 2, and an assembly device 3; the conveying device 2 has a positioning station 21 and an assembly station, and the conveying device 2 includes a conveying table 201, which conveys between the positioning station 21 and the assembly station in sequence; the grille positioning device 1 includes a first gripper 101, a second gripper 102, and a positioning table 103, the first gripper 101 grips the grille 4 onto the positioning table 103 for positioning, the panel component is placed in the conveying table 201, the second gripper 102 grips the grille 4 on the positioning table 103 and places it onto the conveying table 201 in the positioning station 21, the conveying table 201 in the positioning station 21 conveys to the assembly station, and the assembly device 3 assembles the grille 4 onto the panel component.

[0022] It is worth noting that the panel assembly includes injection-molded grille 4 and panel piece (sheet metal spray painting part). The injection-molded grille 4 is provided with a slot or a block, and the panel piece is provided with a block or a slot. The grille 4 is first locked onto the panel piece by rotation, and then the grille 4 and the panel piece are fastened with screws.

[0023] Specifically, firstly, the sheet metal spray-painted part (panel part) is placed on the conveyor table 201. When the conveyor table 201 reaches the positioning station 21, the first gripper 101 starts to work. The first gripper 101 grips an injection-molded grille 4 through its gripping mechanism. The first gripper 101 places the gripped grille 4 on the positioning table 103. This process is the first positioning of the grille 4, which is intended to provide a precise reference for subsequent gripping and assembly operations. After the first gripper 101 completes the placement of the grille 4, the second gripper 102 begins to operate. The second gripper 102 grips the grille 4 on the positioning table 103 and transfers it to the conveyor table 201 in the positioning station 21. The second gripper 102 then places the grille 4 onto the panel piece on the conveyor table 201. At this point, the panel piece is accurately placed in the predetermined position on the conveyor table 201. The second gripper 102 then needs to place the grille 4 in the correct position on the panel piece according to the assembly requirements of the panel piece and the grille 4, so that the grille 4 and the panel piece are initially fitted together. After the grille 4 is placed on the panel piece, the conveyor table 201 transports the panel piece and the grille 4 from the positioning station 21 to the assembly station. The assembly device 3 then begins to operate, precisely assembling the grille 4 and the panel piece according to the preset assembly program and parameters.

[0024] In this embodiment, the positioning platform 103 serves as a temporary storage and positioning platform for the grille 4 throughout the assembly process. The positioning platform 103 is equipped with positioning grooves or structures that match the shape and size of the grille 4, ensuring the accuracy and stability of the grille 4 during its initial positioning. As a transition platform for the grille 4 from the first gripper 101 to the second gripper 102, the positioning platform 103 avoids potential instability or damage that might occur when the grille 4 is directly transferred from the first gripper 101 to the second gripper 102. It provides a stable intermediate storage position for the grille 4, ensuring that the grille 4 is in the optimal posture when gripped by the second gripper 102. The first gripper 101 is responsible for gripping the grille 4 from its storage location (e.g., a tooling vehicle) and placing it on the positioning platform 103, ensuring that the grille 4 is accurately placed in its predetermined position on the positioning platform 103. When the first gripper 101 places the grille 4 on the positioning platform 103, it completes the initial positioning of the grille 4. This process provides the basis for subsequent gripping and assembly operations, ensuring that the grille 4 is in the correct position and posture on the positioning platform 103. The second gripper 102 grips the grille 4 from the positioning table 103 and transfers it to the panel piece on the conveyor table 201, ensuring that the grille 4 can be accurately placed in the predetermined position on the panel piece. When gripping the grille 4, the second gripper 102 can adjust according to the position and orientation of the grille 4 on the positioning table 103 to ensure that the grille 4 fits tightly against the panel piece when placed on it. This process is a key step in ensuring assembly quality. The operation between the positioning table 103, the first gripper 101, and the second gripper 102 is performed in a predetermined sequence. The second gripper 102 can only begin working after the first gripper 101 has completed gripping and initial positioning of the grille 4. This sequential nature ensures the continuity and stability of the entire assembly process. The positioning table 103 provides a stable intermediate storage position for the grille 4, allowing the first gripper 101 and the second gripper 102 to perform gripping and placement operations more accurately. The coordinated work between the first gripper 101 and the second gripper 102 ensures that the grille 4 maintains the correct orientation and position throughout the transfer process. If the first gripper 101 deviates slightly when placing the grille 4, the positioning structure of the positioning table 103 can correct the grille 4 and restore it to the correct position. When the second gripper 102 grips the grille 4, it can further adjust the position and posture of the grille 4 to ensure that it can be accurately placed on the panel. Through the buffering and transition effect of the positioning table 103, and the precise operation of the first gripper 101 and the second gripper 102, the entire assembly process can be carried out efficiently and stably. This synergistic effect not only improves the assembly efficiency, but also significantly improves the assembly quality and reduces errors and fatigue caused by manual operation.

[0025] In this embodiment, the device automates the entire process from gripping, positioning, transferring, assembling, to the final product of the grille 4. Compared to traditional manual assembly, automated operation significantly shortens the assembly time of individual components, thereby improving overall production efficiency. The conveyor 201 circulates between the positioning station 21 and the assembly station, enabling continuous assembly. This continuity reduces pauses and waiting times caused by manual operation, further improving production efficiency. The gripping component and assembly device 3 in the device, through precise mechanical settings and a control system, can quickly and accurately complete gripping, positioning, and assembly actions, avoiding hesitation or inaccurate actions that may occur in manual operation, thus accelerating the production pace. The positioning table 103 and gripping component ensure that the grille 4 is in a precise position and posture before assembly. During the assembly process, the assembly device 3 operates according to preset programs and parameters, ensuring that the torque and position of the screw fastening are accurate, thereby improving assembly quality. The automated assembly device 3 ensures that the assembly process of each component is completely consistent, avoiding fluctuations in assembly quality caused by individual differences, fatigue, and other factors in manual assembly. This consistency is crucial for ensuring the overall quality and performance of the product. Through precise assembly, the grille 4 fits tightly with the panel components, avoiding noise problems caused by loosening or collisions during compressor operation, thereby improving product reliability and service life. Traditional manual assembly requires workers to repeatedly perform operations such as grasping, positioning, rotating, and screwing for extended periods, easily leading to palm and wrist fatigue. This assembly device 3 automates these operations, significantly reducing the labor intensity of workers. The automation device reduces direct contact between workers and assembly parts, lowering physical fatigue and potential injuries caused by frequent operations, while also improving the working environment and worker comfort.

[0026] See also Figures 1 to 9 As shown, the positioning platform 103 includes a support platform 131, a fixed positioning element 132, and a movable positioning element 133. The fixed positioning element 132 is mounted on the support platform 131, that is, the fixed positioning element 132 is fixedly mounted on the top of the support platform 131. The movable positioning element 133 is movably disposed on the support platform 131. The movable positioning element 133 and the fixed positioning element 132 together define the outer periphery of the grille 4.

[0027] Specifically, when the conveyor 201 reaches the positioning station 21, the first gripper 101 starts working. The first gripper 101 grips an injection-molded grille 4 through its gripping mechanism and places the gripped grille 4 onto the support platform 131 of the positioning table 103. At this time, the fixed positioning element 132 and the movable positioning element 133 work together to accurately position the grille 4. The fixed positioning element 132 is installed on the support platform 131 to provide a stable positioning reference and ensure that the grille 4 can be aligned with its predetermined position when placed. The movable positioning element 133 is movably set on the support platform 131 and can be adjusted according to the shape and size of the grille 4. After the first gripper 101 places the grille 4 onto the support platform 131, the movable positioning element 133 will automatically or manually move to a suitable position and, together with the fixed positioning element 132, define the outer periphery of the grille 4 to ensure that the grille 4 is in a precise position and posture on the positioning table 103. After the first gripper 101 completes the placement of the grille 4, the second gripper 102 begins to move. The second gripper 102 accurately grips the grille 4 on the positioning table 103 and transfers the gripped grille 4 to the conveyor table 201 in the positioning station 21. The second gripper 102 then places the grille 4 on the panel piece on the conveyor table 201. At this time, the panel piece has been accurately placed in the predetermined position on the conveyor table 201. The second gripper 102 needs to place the grille 4 in the correct position on the panel piece according to the assembly requirements of the panel piece and the grille 4, so that the grille 4 and the panel piece are initially attached.

[0028] In this embodiment, the fixing element is installed on the support platform 131, and its position and shape are fixed. It provides a stable positioning reference for the grille 4, ensuring that the grille 4 can be aligned with its predetermined position when placed. This fixed reference can effectively reduce assembly problems caused by position deviation. The setting of the fixing element can ensure that the position and posture of the grille 4 are consistent each time it is placed. This repeatability and consistency is particularly important for mass production, ensuring that the assembly quality of each component is always kept at a high level. Since the position of the fixing element 132 is fixed, it can simplify the operation process of the first gripper 101. The first gripper 101 can place the grille 4 on the fixing element 132 according to the preset program without making complicated adjustments. The movable positioning element 133 can be adjusted according to the size and shape of the grille 4. This flexibility allows the positioning table 103 to adapt to different models of grille 4 without replacing the entire positioning table 103 or making complex resets. This is especially important for multi-variety production environments, as it can significantly improve the versatility and adaptability of the device. After the grille 4 is placed on the support table 131, the movable positioning element 133 can further adjust the position and orientation of the grille 4. Even if there is a slight deviation when the first gripper 101 places the grille 4, the movable positioning element 133 can ensure that the grille 4 is finally in the correct position by moving or adjusting. The movable positioning element 133 works together with the fixed positioning element 132 to more accurately define the outer periphery of the grille 4. This dual positioning mechanism can significantly improve the positioning accuracy of the grille 4 and ensure that the grille 4 can fit tightly with the panel parts in the subsequent assembly process.

[0029] See also Figures 1 to 9 As shown, the fixed positioning element 132 is a baffle, and the movable positioning element 133 is a cylinder. The movable positioning element 133 and the fixed positioning element 132 are arranged opposite to each other. The movable positioning element 133 pushes the outer periphery of one side of the grille 4, and the inner wall of the fixed positioning element 132 abuts against the outer periphery of the other side of the grille 4. The movable positioning element 133 and the fixed positioning element 132 define the center position of the grille 4.

[0030] Specifically, the first gripper 101 grips the grille 4 and places it on the support platform 131 of the positioning platform 103. At this time, the grille 4 is roughly placed on the positioning platform 103, but has not yet reached a precise positioning state. The fixed positioning element (baffle) is installed on the support platform 131, and its inner wall abuts against the outer periphery of one side of the grille 4. The position of the baffle is fixed, providing a stable positioning reference for the grille 4. After the grille 4 is placed on the positioning platform 103, the outer periphery of one side of it will contact the inner wall of the baffle, thereby limiting the range of movement of the grille 4 in the horizontal direction. The movable positioning element 133 (cylinder) is arranged opposite to the fixed positioning element 132 (baffle). The piston rod end of the cylinder contacts the outer periphery of the other side of the grille 4. After receiving the control signal, the cylinder pushes the piston rod to extend, so that the piston rod end contacts the outer periphery of the other side of the grille 4 and applies a certain thrust. The thrust of the cylinder will push the grille 4 towards the fixed positioning element 132 (baffle) until the outer periphery of the grille 4 is tightly fitted with the inner wall of the baffle. When the grille 4 is pushed by the cylinder and tightly fitted against the baffle, the outer periphery of the grille 4 is defined by both the fixed positioning element 132 and the movable positioning element 133. Since the relative position of the baffle and the cylinder is fixed, and the direction and magnitude of the cylinder's thrust are controllable, the center position of the grille 4 is precisely defined at a predetermined position between the baffle and the cylinder. After the grille 4 is precisely positioned, the second gripper 102 begins to move. During the gripping process, the second gripper 102 makes appropriate adjustments according to the shape and size of the grille 4. After gripping, the second gripper 102 transfers the grille 4 to the panel on the conveyor table 201 for subsequent assembly operations.

[0031] In this embodiment, the outer periphery of the grille 4 is precisely defined by the relative arrangement of the baffle and the cylinder. The cylinder pushes one side of the outer periphery of the grille 4 to make it fit tightly against the baffle, thereby ensuring that the center position of the grille 4 is accurately positioned. This high-precision positioning is the basis for subsequent assembly operations and can significantly improve assembly quality. The stroke and thrust of the cylinder can be flexibly adjusted by the control system to adapt to grilles 4 of different sizes and shapes. This flexibility allows the positioning table 103 to be quickly switched to different models of grilles 4 without replacing the entire positioning table 103 or performing complex resets. Due to the mobility of the cylinder, this arrangement can adapt to various specifications of grilles 4, improving the versatility and adaptability of the device.

[0032] In one specific implementation, two fixed positioning elements 132 and two movable positioning elements 133 are provided. The two fixed positioning elements 132 are arranged adjacent to each other, and the two movable positioning elements 133 are arranged adjacent to each other. One fixed positioning element 132 and one movable positioning element 133 are arranged opposite to each other. The movement direction of the two movable positioning elements 133 is perpendicular. That is, these four components are installed on the support platform 131 in a circumferentially spaced manner. After the grille 4 is placed on the support platform 131, one movable positioning element 133 first pushes the grille 4 to abut against the opposite fixed positioning element 132, and the other movable positioning element 133 then pushes the grille 4 to abut against the opposite fixed positioning element 132. After ensuring that the grille 4 abuts against the two fixed positioning elements 132, the two movable positioning elements 133 then abut against the grille 4.

[0033] See also Figures 1 to 9 As shown, a vision inspection device is integrated on the support platform 131. The second gripper 102 is communicatively connected to the vision inspection device. The second gripper 102 adjusts the operation path according to the position data of the screw holes of the grille 4 detected by the vision inspection device.

[0034] Specifically, the first gripper 101 places the grille 4 onto the support platform 131 of the positioning table 103. A cylinder pushes the outer periphery of one side of the grille 4, making it tightly fit against the baffle, thus completing the precise positioning of the grille 4. At this point, the center position of the grille 4 is defined. After the grille 4 is precisely positioned on the positioning table 103, the vision inspection device starts working. The vision inspection device is mounted on the support platform 131, and its camera is aimed at the grille 4 to capture its image. The image processing system of the vision inspection device automatically identifies the screw hole positions on the grille 4 and analyzes the image using a preset algorithm to determine the center coordinates of each screw hole. After receiving this data, the control system of the second gripper 102 processes it quickly, calculating the optimal posture and path for gripping the grille 4 to ensure that the screw holes of the grille 4 are precisely aligned with the screw holes on the panel piece when placed on the conveyor table 201. The second gripper 102 adjusts the posture of its gripping mechanism based on the screw hole position data provided by the vision inspection device. If there is a deviation in the position of the screw holes, the second gripper 102 will adjust the position of the grille 4 by means of rotation or translation, so that its screw holes are aligned with the screw holes on the panel. This adjustment is performed in real time to ensure that the grille 4 always maintains the correct posture during the gripping and transfer of the grille 4.

[0035] In this embodiment, the vision inspection device can accurately capture the position data of the screw holes in the grille 4. The second gripper 102 adjusts its gripping posture and placement position in real time based on this data to ensure that the screw holes in the grille 4 are precisely aligned with the screw holes on the panel component. This high-precision alignment reduces assembly problems caused by positional deviations and improves assembly quality. In traditional assembly processes, screw hole alignment usually relies on manual visual inspection and adjustment, which is prone to errors and fatigue-related mistakes. This setup, through automated detection and adjustment, greatly reduces manual intervention and improves the consistency of assembly accuracy. The collaborative work of the vision inspection device and the second gripper 102 automates the gripping and placement process. The vision inspection device can quickly detect the screw hole position, and the second gripper 102 can quickly adjust its posture and perform operations based on the detection results, reducing the time required for manual operation. The vision inspection device provides real-time feedback, and the second gripper 102 can dynamically adjust based on this data. This real-time capability makes the entire assembly process smoother, reduces repeated adjustments and rework time caused by positional deviations, and thus improves production efficiency. The visual inspection device can identify the screw hole positions of grilles 4 of different sizes and shapes. The second gripper 102 makes corresponding adjustments based on this data. This flexibility allows the assembly device 3 to quickly switch to different models of grilles 4 without replacing the entire positioning table 103 or readjusting the equipment, which significantly improves the versatility and flexibility of the device. Through the rapid detection of the visual inspection device and the real-time adjustment of the second gripper 102, the device can quickly switch between grilles 4 of different specifications without complicated equipment adjustments.

[0036] See also Figures 1 to 9 As shown, the assembly device 3 includes a grid rotating device 5, and the assembly station includes a grid rotating station 22. The second gripper 102 places the grid 4 onto the conveyor table 201 in the positioning station 21. At this time, the grid 4 is placed on the panel piece. The conveyor table 201 in the positioning station 21 transports the grid to the grid rotating station 22. The working end of the grid rotating device 5 acts on the conveyor table 201 in the grid rotating station 22 so that the grid rotating device 5 drives the grid 4 to rotate and install it on the panel piece.

[0037] Specifically, the second gripper 102 places the grille 4 onto the panel piece on the conveyor table 201 in the positioning station 21. At this point, the grille 4 and the panel piece are initially attached, but the final assembly is not yet complete. The conveyor table 201 in the positioning station 21 transports the assembly containing the grille 4 and the panel piece to the grille rotation station 22. The working end of the grille rotation device 5 is located above or to the side of the grille rotation station 22. Depending on the configuration, its working end can be a rotating shaft, a rotating arm, or other suitable structure. The device is in a standby state before the assembly arrives at the rotation station, ready to rotate the grille 4. The rotation station is usually equipped with sensors (such as photoelectric sensors, proximity switches, etc.) to detect whether the assembly on the conveyor table 201 has accurately arrived at the rotation station. Once the assembly is detected to be in place, the sensor sends a signal to the control system of the grille rotation device 5 to start the rotation operation. The working end (such as a rotating shaft or rotating arm) of the grille rotating device 5 contacts the grille 4. This contact can be direct contact with the edge of the grille 4 or clamping a specific part of the grille 4 using a clamping device. This contact method must ensure that the grille 4 is not damaged and that sufficient rotational torque is provided. The drive mechanism (such as a motor or cylinder) of the grille rotating device 5 is activated, driving the working end to rotate. The rotation direction and angle are set according to the assembly requirements of the grille 4 and the panel component. For example, if the grille 4 needs to rotate around a certain axis to align with the screw holes on the panel component, the drive mechanism will operate according to the preset rotation angle and direction. After the grille 4 is rotated to the correct position, screws are fastened to the connection between the grille 4 and the panel component, completing the final assembly.

[0038] In this embodiment, the grille rotation device 5 can precisely control the rotation angle of the grille 4, ensuring that the screw holes or other connecting parts on the grille 4 are precisely aligned with the corresponding parts on the panel. This precise alignment is the basis for subsequent screw fastening or other fixing operations, significantly improving assembly quality. Through automated control, the grille rotation device 5 can reduce errors caused by manual operation. When manually rotating and installing the grille 4, angular deviations or misalignments may occur. The rotation device can achieve high-precision rotation operations, ensuring consistency in each assembly. The grille rotation device 5 automates the rotation and installation process, reducing manual intervention. Workers only need to place the grille 4 on the conveyor table 201, and the subsequent rotation and installation operations are automatically completed by the device, thereby improving production efficiency. The rotation device can quickly adapt to different models of grille 4. By adjusting the rotation angle and drive parameters, it can quickly switch to different specifications of grille 4, reducing downtime caused by changing product models.

[0039] See also Figures 1 to 9As shown, the grid rotation device 5 includes a rotation drive unit 501 and a rotating disk 502. The rotating disk 502 is mounted on the drive end of the rotation drive unit 501. The rotation drive unit 501 drives the rotating disk 502 to move and rotate. When the rotating disk 502 moves to the conveyor table 201 in the grid rotation station 22, the rotating disk 502 is connected to the grid 4 away from the end face of the rotation drive unit 501. The rotating disk 502 drives the grid 4 to rotate and be mounted on the panel.

[0040] Specifically, the grid rotation device 5 is installed above or to the side of the grid rotation station 22. The rotation drive unit 501 is connected to the rotating disk 502, and the end face of the rotating disk 502 is preferably configured to connect with the grid 4. When the conveyor 201 arrives at the rotation station with the grid 4 and the panel piece, the control system of the grid rotation device 5 receives a signal and starts the rotation drive unit 501. The rotation drive unit 501 drives the rotating disk 502 to move above the conveyor 201 in the grid rotation station 22. The rotation drive unit 501 can be a motor, cylinder, or other drive device, and its configuration ensures that the rotating disk 502 can move accurately above the grid 4. The end face of the rotating disk 502 is connected to the grid 4. The connection method can be mechanical clamping (such as grippers holding the edge of the grid 4) or vacuum adsorption (such as a vacuum suction cup adsorbing the surface of the grid 4). The specific method can be flexibly selected. The rotary drive unit 501 is activated, driving the rotary disk 502 and the grille 4 connected thereto to rotate. The rotation angle and direction are set according to the assembly requirements. For example, if the grille 4 needs to rotate around a certain axis to align with the screw holes on the panel, the rotary drive unit 501 will operate according to the preset rotation angle and direction. The rotary disk 502 drives the grille 4 to rotate, so that its screw holes or other connecting parts are precisely aligned with the corresponding parts on the panel. After the grille 4 is rotated to the correct position, the screws are fastened to the connection between the grille 4 and the panel, completing the final assembly.

[0041] See also Figures 1 to 9 As shown, the end face of the rotating disk 502 facing the conveyor table 201 is provided with multiple strip grooves 521. The multiple strip grooves 521 are arranged at intervals along the circumference of the rotating disk 502, and the strip grooves 521 are pressed onto the grid 4.

[0042] In this embodiment, the design of the spoke grooves 521 increases the contact area between the rotating disk 502 and the grille 4, allowing the gripping force to be distributed more evenly on the surface of the grille 4. This evenly distributed gripping force effectively prevents the grille 4 from sliding or shifting during rotation, thereby improving the stability of the rotation operation. The spacing of the spoke grooves 521 can accommodate grilles 4 of different shapes and sizes. Even if the edges of the grille 4 are irregular, the spoke grooves 521 can ensure sufficient contact area between the grille 4 and the rotating disk 502 through pressing, thus achieving stable gripping and rotation. Because the spoke grooves 521 ensure a tight contact between the grille 4 and the rotating disk 502, the rotation drive unit 501 can more precisely control the rotation angle. This precise control is key to ensuring the alignment of the grille 4 with the screw holes of the panel component, thereby improving the assembly accuracy. The spacing of the bar grooves 521 can distribute the pressure applied by the rotating disk 502 to multiple points, rather than concentrating it in a certain area. This distributed pressure can further protect the surface of the grid 4 and reduce deformation or damage caused by excessive local pressure. The depth and width of the bar grooves 521 can be adjusted according to the thickness of the grid 4, thereby adapting to grids 4 of different thicknesses. This flexibility allows the rotating disk 502 to be applicable to grids 4 of various specifications, enhancing the versatility and adaptability of the device.

[0043] See also Figures 1 to 13 As shown, the assembly device 3 also includes a screw fastening device 6 and a vision assembly device 3. The assembly station includes a screw fastening station 23. The conveyor table 201 in the grid rotation station 22 is transported to the screw fastening station 23. The vision assembly device 3 identifies the position of the screw hole on the grid 4. The working end of the screw fastening device 6 moves to the position of the screw hole on the grid 4 to complete the screw fastening.

[0044] Specifically, the grille 4 and panel assembly, having undergone rotation and installation at the grille rotation station 22, are conveyed by the conveyor 201 to the screw fastening station 23. The screw fastening station 23 is equipped with a positioning device (such as a positioning baffle, sensor, etc.) to confirm whether the assembly on the conveyor 201 has accurately reached the designated position. Once the assembly arrives at the screw fastening station 23, the positioning device sends a signal to notify the screw fastening device 6 to prepare to start work. A vision assembly device 3 (such as a high-precision camera) is installed above or to the side of the screw fastening station 23, with its lens aimed at the connection point between the grille 4 and the panel assembly. After activation, the vision assembly device 3 begins to capture the positions of the screw holes on the grille 4. The vision assembly device 3 uses image processing algorithms to identify the center position of the screw holes and converts this positional data into machine-readable coordinate information. The working end of the screw fastening device 6 (such as an electric screwdriver or other screw fastening tool) moves above the first screw hole based on the screw hole position data provided by the vision assembly device 3. The screw supply system (such as a vibratory feeder, screw conveyor track, etc.) delivers screws to the working end of the screw fastening device 6. The screw supply system ensures that the screws accurately reach the clamping position of the fastening tool. After the working end of the screw fastening device 6 clamps the screw, it precisely inserts the screw into the screw holes of the grille 4 and the panel component based on the screw hole position data provided by the vision assembly device 3. During insertion, the device performs the screw fastening operation according to a preset torque, ensuring the screw is fastened in place without damaging the components. After the screw fastening device 6 completes the fastening operation, the vision assembly device 3 checks the fastened screws again to confirm that they are properly fastened and without loosening. If any defects are found, the device will issue an alarm, and the worker can manually repair them.

[0045] In this embodiment, the vision assembly device 3 can accurately identify the screw hole positions, and the screw fastening device 6 performs precise screw fastening operations based on these position data. This high-precision fastening operation can significantly improve assembly quality and reduce assembly problems caused by incorrect screw fastening. The automated screw fastening device 6 reduces errors caused by manual operation and improves the consistency of assembly accuracy. When manually fastening screws, problems such as inconsistent torque and loose screws are prone to occur, while the automated device can avoid these problems. The screw fastening device 6 automates the screw fastening process and reduces manual intervention. Workers only need to place the assembly on the conveyor table 201, and the subsequent fastening operation is automatically completed by the device, thereby improving production efficiency. The device can quickly complete the screw fastening operation, reducing the assembly time of a single component. By optimizing the fastening path and increasing the fastening speed, the device can complete the fastening of multiple screws in a short time. Precise fastening reduces assembly problems caused by improper screw fastening, such as loose screws or loose fit between panel parts and grille 4. These problems are common in traditional manual assembly, while the screw fastening device 6 can significantly reduce the occurrence of these problems. By reducing assembly errors, the overall quality and reliability of the product are improved, and the after-sales maintenance and rework costs caused by assembly problems are reduced.

[0046] See also Figures 1 to 13 As shown, the conveying device 2 is equipped with multiple blocking lifting devices 7. The blocking lifting device 7 is a cylinder. The positioning station 21 and the assembly station are respectively equipped with blocking lifting devices 7. The blocking lifting device 7 is used to lift the conveying table 201 of the corresponding station according to the assembly requirements.

[0047] Specifically, the conveyor table 201 is transported by a conveyor belt. The positioning station 21, the grid rotation station 22, and the screw fastening station 23 are arranged sequentially along the conveyor belt's transport direction. Each conveyor table 201 will pass through these stations in sequence. To improve installation efficiency, multiple conveyor tables 201 are placed on the conveyor belt simultaneously. When the conveyor table 201 reaches the corresponding station, the panel parts are first corrected by guide rails on both sides of the belt. That is, the distance between the guide rails is adjustable. For example, when the conveyor table 201 reaches the positioning station 21, the blocking lifting device 7 rises to position the conveyor table 201 at the designated position. The second gripper 102 places the grid 4 into the corresponding assembly hole of the panel part. After the action is completed, the blocking lifting device 7 descends, and the belt conveyor sequentially transports the parts to the subsequent stations.

[0048] In this embodiment, multiple conveyor platforms 201 are placed side by side on the conveyor belt. Each conveyor platform 201 passes sequentially through a positioning station 21, a grid rotation station 22, and a screw fastening station 23. This multi-station setup allows multiple parts to be assembled simultaneously at different stations, greatly improving production efficiency. After a conveyor platform 201 completes assembly at a station, the blocking lifting device 7 descends, and the conveyor belt automatically moves the conveyor platform 201 to the next station. Simultaneously, the next conveyor platform 201 enters the current station for operation. This continuous production method reduces downtime and improves the efficiency of the entire assembly line. The blocking lifting device 7 (cylinder) corresponding to each station can rise when the conveyor platform 201 reaches the designated position, precisely blocking the movement of the conveyor platform 201 and stopping it at the designated position. This precise positioning is the basis for subsequent assembly operations, ensuring that the operation at each station is performed in the correct position.

[0049] See also Figures 1 to 13 As shown, the first gripper 101 and the second gripper 102 are robots.

[0050] In this embodiment, the robot, through its built-in high-precision sensors and control system, can accurately perform grasping and placement operations. Based on preset programs and position data, the robot can precisely grasp and place the grille 4 into the designated position, ensuring the assembly accuracy of the grille 4 and the panel component. The robot can complete the same task with extremely high repeatability, and the consistency of each grasping and placement operation is very high, reducing errors caused by manual operation and ensuring consistent quality for each assembly. The robot can achieve fully automated grasping and placement operations, reducing human intervention. This automation not only improves production efficiency but also reduces downtime and errors caused by manual operation. The robot can complete some dangerous or highly repetitive tasks, reducing the risk of safety accidents caused by improper operation or fatigue of workers.

[0051] It is worth noting that in this embodiment, the entire device is typically composed of multiple subsystems, including a conveying device 2, a gripping device (robot), a positioning device, a rotating device, a screw fastening device 6, a vision inspection device, etc. These devices are coordinated and managed by a central control system (such as a PLC, industrial computer, or robot controller). The central control system is responsible for receiving signals from each device and sending instructions to each device to ensure the smooth progress of the entire assembly process.
