Description

Technical Field

[0001] This invention relates to a screen processing equipment, and more particularly to a fully automatic screen pressing and cover installation machine. Background Technology

[0002] The screen pressing rope technique is used to fill the pre-reserved grooves on the height edge of wooden screens. During the operation, a fabric thread similar to window edge banding strip is used to fill the grooves on the height of the wooden screen, forming an unclosed loop from the starting point to the end point. The fabric thread is then cut, and aluminum alloy parts are installed on the unclosed area.

[0003] Currently, companies often use manual labor for the screen rope pressing process. One end of the fabric thread is manually positioned and fixed, and then the edge is wrapped according to the position of the groove. A small hammer is used to press it firmly while wrapping the edge. After reaching the designated position, the fabric thread is cut and pressed into the groove. After the rope pressing work is completed, the aluminum alloy parts are installed. The aluminum alloy parts are manually positioned and installed and screwed in manually.

[0004] Currently, the rope pressing technology for screens often uses manual assembly line work, which is costly and can lead to worker fatigue. The rope pressing work is done manually, and the starting and ending points are inconsistent each time, resulting in varying degrees of pressure on the fabric threads and different work precision for each person. The installation of aluminum alloy parts is also done manually, with different installation positions each time and different installation precision for each person. Summary of the Invention

A crank-type cord pressing assembly 1014 is mounted at the other end of the side of the rotating carrier plate 1010. The fabric thread gripper cylinder 1013 is used to grip the fabric thread output from the fabric thread output assembly 1011 and moves the fabric thread to the rear end of the crank-type cord pressing assembly 1014 via the longitudinal mover 1012. The crank-type cord pressing assembly 1014 is used to press the fabric thread into the slot 1a1 of the screen 1a. Since the screen 1a has slots 1a1 around its perimeter for pressing the fabric thread, this design can drive the rotating carrier plate 1010 to move around the screen 1a. When the fabric thread is pressed into the edge of the screen 1a, the rotating cylinder 109 drives the rotating carrier plate 1010 to rotate 90 degrees, so that the crank-type cord pressing assembly 1014 can continue to press the cord on the other side of the screen 1a.

[0033] In this embodiment, the fabric thread output assembly 1011 includes a storage wheel 10111 mounted on the rotating carrier plate 1010.

A cutting device 10116 is provided between the transverse guide rubber-coated roller assembly 10113 and the steering guide rubber-coated roller 10114. The cutting device 10116 is used to cut the fabric thread. This design is used for automatic feeding of the fabric thread. The fabric thread is clamped by the fabric thread clamping cylinder 1013 and moved to the rear end of the crank pressing rope assembly 1014. After the pressing rope work of the entire screen 1a is completed, the fabric thread is automatically cut by the cutter of the cutting device 10116.

[0034] In this embodiment, the crank-to-rope assembly 1014 includes a connecting rod drive servo 10141, a first compression connecting rod 10142, a second compression connecting rod 10143, two crank slide rails 10144, and a compression crank 10145.

This design is used so that when the fabric thread clamping cylinder 1013 clamps the fabric thread and moves to the rear end of the crank pressing assembly 1014, the linkage drive servo 10141 drives the first compression connecting rod 10142, which indirectly drives the second compression connecting rod 10143 to push the entire compression crank 10145 forward between the two crank slide rails 10144, so that the crank wheel 101451 presses the fabric thread into the slot 1a1 of the screen 1a.

[0035] In this embodiment, the structure of the screen loading mechanism 3 and the screen unloading moving mechanism 4 is identical. Both the screen loading mechanism 3 and the screen unloading moving mechanism 4 include an AGV moving trolley 31. The AGV moving trolley 31 moves according to a pre-set tracking route 311.

The screw lifting platform plate 32 is provided with a limiting sliding groove 321 adapted to the storage limiting frame plates 33. Through the tension springs 35 and the four-bar linkage 34 in conjunction with the four storage limiting frame plates 33, the screen 1a of the screw lifting platform plate 32 can be automatically limited. This design can be used for various models of screen 1a, and the screen 1a in the screw lifting platform plate 32 can be driven to rise or fall by the screw drive motor.

[0036] In this embodiment, the three-axis air gripper assembly 8 includes a gripper lateral movement mechanism 81 and a lateral movement carrier 82 connected to the gripper lateral movement mechanism 81. One end of the lateral movement carrier 82 is equipped with a pulley drive motor 83 and a drive pulley 84 connected to the pulley drive motor 83. The other end of the lateral movement carrier 82 is equipped with a driven pulley 85 and a gripper lifting cylinder 86. A transmission belt 87 connects the drive pulley 84 and the driven pulley 85. A lifting connecting plate 88 is provided at the upper end of the lifting output shaft of the gripper lifting cylinder 86, and a lifting rotating spindle 89 is provided at the lower end of the lifting connecting plate 88. A rotating bearing seat 810 is fixed at the lower end of the driven pulley 85, and a gripper mounting plate 811 is provided below the rotating bearing seat 810.

This design allows the air gripper 813 to hold the aluminum part 2a output by the aluminum part storage and conveying device 9, rise and move back a certain distance, and then indirectly drive the driven pulley 85 to rotate 180 degrees through the pulley drive motor 83. This causes the lifting rotating spindle 89 to rotate 180 degrees with the cooperation of the locking groove and the locking protrusion, thereby rotating the aluminum part 2a held by the air gripper 813 by 180 degrees. Then, the gripper lifting cylinder 86 drives the entire lifting rotating spindle 89 to descend to the height of the aluminum part 2a to be assembled on the screen 1a.

[0037] In this embodiment, the aluminum component storage and conveying device 9 includes an aluminum component storage bin 91. An aluminum component conveyor belt 92 is installed at the bottom of the aluminum component storage bin 91. Several aluminum components 2a are stacked inside the aluminum component storage bin 91.

Under the influence of gravity, the U-shaped aluminum part cover plate at the bottom of the aluminum part storage bin 91 is conveyed forward by the aluminum part conveyor belt 92 and slides down into the aluminum part loading groove 94 via the guide ramp 93. When the through-beam sensor detects aluminum part 2a, the aluminum part conveyor belt 92 stops conveying. The aluminum part loading groove 94 is provided with an avoidance clamping opening 95 adapted to the air gripper 813, which facilitates the air gripper 813 to exit from the aluminum part loading groove 94. The aluminum component 2a is clamped; the aluminum component mounting area 7 includes a concave plate groove 96 adapted to the screen 1a. One side of the concave plate groove 96 is provided with an avoidance notch 97 adapted to the U-shaped aluminum component cover plate. This design allows the screen 1a to be fitted into the concave plate groove 96. Positioning push plates can be added to the four sides of the concave plate groove 96 except for one side of the avoidance notch 97, thereby positioning the screen 1a in the concave plate groove 96. Then, the aluminum component clamped by the air gripper 813 is inserted into the screen 1a.

[0038] In this embodiment, the screw-driving mechanism 5 includes a four-axis screw-driving device 51 and a CCD camera 52 located on the side of the four-axis screw-driving device 51.

[0039] In this embodiment, the working process of the present invention is as follows: At the start of the work, the screen model to be processed is selected on the control panel in the MCU control system. The AGV moving trolley of the screen loading mechanism loads the screen in the waiting area. After loading is completed, the AGV moving trolley follows the track to the rope pressing work area. The screen three-axis moving mechanism moves to the rope pressing work area and moves down the suction cup to pick up and lift the screen. After lifting to the specified height, it waits for the rope pressing device to respond. After the rope pressing device finishes its work, it cuts the screen. At this time, the screen three-axis moving mechanism moves the screen above the aluminum part mounting area and moves it down. The aluminum parts are placed on the concave plate loading slot to await installation. At this time, the aluminum parts are transported by the aluminum parts conveyor belt on the aluminum parts storage and conveying device. The three-axis air gripper assembly clamps and installs the aluminum parts. After the aluminum parts are installed, the three-axis moving mechanism of the screen continues to move the screen, moving the screen to the AGV moving trolley at the screen unloading moving mechanism and placing it on the AGV moving trolley. At this time, the AGV moving trolley moves forward to the screw installation area. After taking pictures with the CCD camera, the screws are installed one by one by the four-axis screw-driving device. After the trolley in this area is fully loaded, it drives into the processing completion area to wait for unloading.
