[0036] In this invention, for clarity, the following description is provided: The observer faces the attached... Figure 1 In the observation process, the observer's left front side is designated as left, the observer's right rear side as right, the observer's left rear side as rear, the observer's right front side as front, the observer's top as top, and the observer's bottom as bottom.

[0037] See Figures 1 to 16This embodiment provides an automatic flipping device, including a screen rotating carrier plate 1. The upper end surface of the screen rotating carrier plate 1 is provided with a screen mounting groove 101, and the lower end surface of the screen rotating carrier plate 1 is provided with an opening 102, which extends upward through the bottom wall of the screen mounting groove 101. The length of the screen rotating carrier plate 1 and the screen mounting groove 101 extends in the left-right direction, and the width of the screen rotating carrier plate 1 and the screen mounting groove 101 extends in the front-back direction. The left and right ends of the screen rotating carrier plate 1 are respectively movably connected to the top of the rotating table columns 2 on the left and right sides. The left or right end of the screen rotating carrier plate 1 is connected to the cylinder rotation shaft of the rotating cylinder 3, and the rotating cylinder 3 can drive the screen rotating carrier plate 1 to flip up and down. The upper end surface of the screen rotating carrier plate 1 is also provided with a plurality of pressure blocks 4 distributed sequentially along the edge of the screen mounting groove 101. The pressure blocks 4 can press or release the product 5 in the screen mounting groove 101. Functions: (1) The upper end of the rotating screen carrier plate is provided with a screen mounting groove, and the lower end of the rotating screen carrier plate is provided with an opening that extends upward through the bottom wall of the screen mounting groove. This allows the product (which can be a dual-panel screen) to be placed downward into the screen mounting groove when the rotating screen carrier plate is flipped upward. Then, when the rotating screen carrier plate is flipped downward, double-sided tape can be manually applied to the back of the product (which can be a dual-panel screen) through the opening. (2) The left and right ends of the rotating screen carrier plate are movably connected to the top of the rotating table columns on the left and right sides, respectively. The left or right end of the rotating screen carrier plate is connected to the cylinder rotation shaft of the rotating cylinder. The rotating cylinder can drive the rotating screen carrier plate to flip up and down. Driven by the rotary cylinder, the screen rotating carrier can rotate the product (which can be a double screen) up and down; (3) The upper surface of the screen rotating carrier is also provided with several pressure blocks distributed sequentially along the edge of the screen mounting slot. The pressure blocks can press down or release the product in the screen mounting slot, so that the product in the screen mounting slot can be pressed down by the pressure blocks. In this way, the product will not fall out of the screen mounting slot when the screen rotating carrier is rotated down. After the double-sided tape is pasted, the screen rotating carrier can be rotated up by the rotary cylinder first, and then the pressure blocks can be released from the product (which can be a double screen) in the screen mounting slot, so that the robot can pick up the front of the product (which can be a double screen) in the future. As can be seen from the above analysis, the technical solution of the present invention can avoid the risk of easy breakage or damage to long (1.1 to 1.2 meters) double screens when manually picking up and flipping them.

[0038] See Figures 2 to 8 The following is a detailed description of the flipping mechanism: The screen clamping mechanism is rotated 180 degrees or 195 degrees by a rotating cylinder, which makes it convenient for manual application of double-sided adhesive tape.

[0039] Specifically, the left and right ends of the screen rotating carrier plate 1 are respectively provided with screen rotating carrier plate mounting seats 6, and the left and right ends of the screen rotating carrier plate mounting seats 6 are respectively provided with a rotary drive shaft 7 and a rotary driven shaft 8; the top of the rotating table column 2 is provided with a first bearing seat 9, and the first bearing seat 9 is provided with a first bearing 10. The rotary drive shaft 7 and the rotary driven shaft 8 are respectively engaged with the first bearing 10 on the left and right sides; the rotary cylinder 3 can rotate at an angle ≥180 degrees. Function: It provides a specific structure for the left and right ends of the screen rotating carrier plate 1 to be movably connected to the top of the left and right rotating table columns 2.

[0040] Specifically, the top of the left-side rotating platform column 2 is also provided with a rotating cylinder mounting plate 11, which is located to the left of the first bearing seat 9; the rotating cylinder 3 is located on the rotating cylinder mounting plate 11, and the rotating drive shaft 7 passes through the first bearing 10 to the left and is connected to the cylinder rotation shaft of the rotating cylinder 3 through the rotating cylinder connecting flange 12; the rotating angle of the rotating cylinder 3 is set to 195 degrees, and its function is to provide a specific structure for connecting the left end of the screen rotating carrier plate 1 to the cylinder rotation shaft of the rotating cylinder 3.

[0041] The working process of each component during runtime:

[0042] The rotating platform column 2 can be fixed on both sides of the Y-axis motion base plate 26 as support points for the flipping platform. The first bearing seat 9 serves as the rotation center of the flipping platform. The rotary cylinder mounting plate 11 is installed on the rotating platform column 2 as the fulcrum of the rotary cylinder. The rotary cylinder 3 is fixed on the rotary cylinder mounting plate 11. When the cylinder rotation shaft moves, the torque is transmitted to the rotary drive shaft 7 through the rotary cylinder connecting flange 12. The rotary drive shaft 7 drives the screen rotation carrier plate mounting seat 6 and the screen rotation carrier plate 1 to rotate together, realizing the entire flipping platform flipping 195 degrees. As can be seen from the above analysis, this equipment can flip the product to a 195-degree tilt angle, so that the back of the screen is flipped upwards, which greatly facilitates the manual application of double-sided tape to the back of the product.

[0043] See Figures 9 to 12 The clamping mechanism is described in detail below: a cylinder is used as the force to press the screen and keep it in the Z-axis direction.

[0044] Specifically, the front and rear sides of the screen rotating carrier plate 1 are respectively provided with gripper push arm rotating shafts 13 extending left and right. The left and right ends of the gripper push arm rotating shafts 13 are respectively engaged with the second bearings 15 in the second bearing seats 14. The second bearing seats 14 are located on the side wall of the screen rotating carrier plate 1. The gripper push arm rotating shafts 13 are connected to the middle of the gripper push arm 16. The top end of the gripper push arm 16 is connected to the gripper adapter strip 17 extending left and right. The bottom end of the gripper push arm 16 is connected to the drive device. The gripper adapter strip 17 is connected to the pressure block mounting strip 18 extending left and right. The pressure block mounting strip 18 is provided with several pressure blocks 4 distributed sequentially in the left and right direction. The end of the pressure block 4 away from the pressure block mounting strip 18 is bent towards the length edge of the screen mounting groove 101. Function: Driven by the drive device, the gripper push arm 16 can be rotated around the gripper push arm rotating shaft 13, thereby causing the pressure blocks 4 to press and release the product 5.

[0045] Specifically, the pressure block 4 includes a first screen Z-direction pressure block 401, a second screen Z-direction pressure block 402, and a third screen Z-direction pressure block 403. The length of the first screen Z-direction pressure block 401 is shorter than the length of the second screen Z-direction pressure block 402, and the length of the second screen Z-direction pressure block 402 is shorter than the length of the third screen Z-direction pressure block 403. Among the pressure block mounting strips 18 on both the front and rear sides, one side of the pressure block mounting strip 18 is equipped with the first screen Z-direction pressure block 401 and the second screen Z-direction pressure block 402, and the other side of the pressure block mounting strip 18 is equipped with the first screen Z-direction pressure block 401 and the third screen Z-direction pressure block 403. Function: By setting pressure blocks 4 of different lengths, the product 5 can be better pressed down.

[0046] Specifically, the driving device is a cylinder 19. Cylinder bearing seats 20 are respectively provided on the front and rear sides of the lower end face of the rotating carrier plate 1. A third bearing (not shown in the figure) is provided inside the cylinder bearing seat 20. The third bearing cooperates with the cylinder rotation shaft 21 extending left and right, and the cylinder rotation shaft 21 is connected to the cylinder 19. The bottom end of the gripper push arm 16 is provided with a cylinder push arm rotating shaft 22 extending left and right. The cylinder push arm 23 of the cylinder 19 is movably connected to the cylinder push arm rotating shaft 22. Function: This provides the specific structure of the driving device, thereby enabling the gripper push arm 16 to rotate around the gripper push arm rotating shaft 13. When the cylinder push arm 23 is working, the cylinder 19 also rotates around the cylinder rotation shaft 21.

[0047] The working process of each component during runtime:

[0048] The second bearing seat 14 and the cylinder bearing seat 20 are fixed on the screen rotating carrier plate, serving as the static connection support point of the entire motion mechanism. After the screen positioning structure completes X / Y positioning, the cylinder 19 is pushed out, and the cylinder push arm 23 drives the gripper push arm 16 to swing around the gripper push arm rotation axis 13. The gripper adapter strip 17 is fixed on the gripper push arm 16, and the pressure block mounting strip 18 is fixed on the gripper adapter strip 17. The first screen Z-direction pressing block 401, the second screen Z-direction pressing block 402, and the third screen Z-direction pressing block 403 are respectively fixed on the pressure block mounting strip 18. As the gripper push arm 16 swings, the dual-screen module (product) is pressed or released.

[0049] See Figure 13 The following is a detailed description of the screen positioning mechanism: a cylinder is used as the force to move the screen to the designated position in the X / Y direction.

[0050] Specifically, at least two screen Y-direction positioning and pushing cylinder assemblies 24 are provided on the front or rear edge of the screen mounting slot 101, and at least one screen X-direction positioning and pushing cylinder assembly 25 is provided on the left or right edge of the screen mounting slot 101. Structural relationship explanation: After the product 5 (which can be a dual-screen module) is placed in the screen mounting slot 101, the screen X-direction positioning and pushing cylinder assembly 25 pushes the dual-screen module (product) to the left in the X direction, bringing it closer to the left and holding it there, thus achieving positioning in the X direction; the two sets of screen Y-direction positioning and pushing cylinder assemblies 24 push the dual-screen module (product) to the rear in the Y direction, bringing it closer to the rear and holding it there, thus achieving positioning in the Y direction. This ensures that the position of the dual-screen module (product) is consistent each time the robot grasps it. Therefore, this equipment can achieve consistent product positioning for robots in upstream and downstream processes.

[0051] Specifically, the bottom ends of the left and right rotating platform columns 2 extend downwards and connect to the left and right ends of the Y-axis motion base plate 26, respectively. A flipping space is provided between the screen rotating carrier plate 1 and the Y-axis motion base plate 26, allowing the screen rotating carrier plate 1 to flip up and down within the flipping space. Function: The rotating platform columns are mounted on the Y-axis motion base plate, providing the screen rotating carrier plate with a flipping space while simultaneously driving the movement of the screen rotating carrier plate.

[0052] See Figures 14 to 16 The following is a detailed description of the screen transmission mechanism: The clamping mechanism and the screen are moved backward and transmitted through the linear motion module to facilitate robot grasping.

[0053] Specifically, the automatic flipping device also includes a machine platform 27, with a machine platform panel 28 on the top of the machine platform 27. Y-axis auxiliary linear guide rails 29 extending forward and backward are respectively provided on the left and right sides of the machine platform panel 28. Y-axis lifting blocks 30 are respectively provided on the left and right sides of the bottom of the Y-axis moving base plate 26, and the Y-axis lifting blocks 30 on the left and right sides slide forward and backward with the Y-axis auxiliary linear guide rails 29 on the left and right sides, respectively. Function: The Y-axis moving base plate 26 can move forward and backward along the Y-axis auxiliary linear guide rails 29.

[0054] Specifically, a Y-axis linear module 31 extending forward and backward is provided in the middle of the equipment platform 28. The Y-axis linear module 31 is connected to the middle of the Y-axis motion base plate 26 and drives the Y-axis motion base plate 26 to move forward and backward. Function: By installing the Y-axis linear module and the Y-axis auxiliary linear slide rail on the equipment platform, the Y-axis linear module can be used to drive the Y-axis motion base plate 26 to move forward and backward along the Y-axis auxiliary linear slide rail, thereby ensuring smooth movement of the Y-axis motion base plate.

[0055] Specifically, the Y-axis motion cable chain 32 is mounted on the Y-axis motion base plate 26 to protect the wiring harness and air pipes from scratching during equipment operation. The human-machine interface touch screen 33 and the equipment operation button box 34 are located on the right rear side of the equipment platform 28. The human-machine interface touch screen 33 is used for editing and operating the equipment operation interface, and the equipment operation button box 34 includes start, pause, reset, and emergency stop buttons. The rear side of the equipment platform 27 has an electrical box door. The interior of the equipment platform 27 contains electrical controls, servo motor drivers, etc. The Y-axis linear module can be controlled by the servo motor driver to position at any point, enabling the robot to pick up the screen in the next process.

[0056] Action Description: The Y-axis linear module 31 is driven by a servo motor to provide power and precise movement to the Y-axis motion base plate 26 in the Y-axis direction, completing the Y-axis positioning work. Note: Position 1 of the Y-axis motion base plate 26 is the manual operation position (at this time, the product is flipped 180 degrees under the action of the rotary cylinder, and the back is facing up for double-sided tape application). Position 2 of the Y-axis motion base plate 26 is the robot's loading and unloading position (at this time, the product is flipped back to the front).

[0057] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
